Infectious keratitis in leprosy. (1/186)

AIM: To describe leprosy characteristics, ocular features, and type of organisms that produce infective corneal ulcers in leprosy patients. METHOD: The records of all leprosy patients admitted for treatment of corneal ulcers between 1992 and 1997 were reviewed. RESULTS: 63 leprosy patients, 53 males and 10 females, are described. 16 were tuberculoid and 47 lepromatous. 25 patients had completed multidrug therapy. 10 patients had face patches, eight had type I reaction, and 10 had type II reaction. 43 (68%) patients had hand deformities. In 54% of patients pain was absent as a presenting symptom. 19 patients gave a history of trauma. In 15 patients ulcers had also occurred on the other eye, five of them having occurred during the study period and the rest before 1992. Of the 68 eyes with corneal ulcers, 28 had madarosis, 34 had lagophthalmos, nine had ectropion, three had trichiasis, six had blocked nasolacrimal ducts, and 39 decreased corneal sensation. In 14 eyes, a previous lagophthalmos surgery had been done. 16 patients were blind at presentation. 32% of ulcers were located centrally. After treatment only 18% of the eyes showed visual improvement. Five types of fungus were cultured, two of them rare ocular pathogens. CONCLUSIONS: Corneal ulcers occur more in males and in the lepromatous group of patients. Decreased corneal sensation, lagophthalmos and hand deformity are closely associated. Indigenous treatment and late presentations were notable in many patients. Visual outcome is not good. There is increased risk of developing an ulcer in the other eye. Fungal corneal ulcers are not uncommon.  (+info)

Inhibition of apoptosis by ionomycin and zinc in peripheral blood mononuclear cells (PBMC) of leprosy patients. (2/186)

PBMC from tuberculoid (BT/TT) and lepromatous leprosy (BL/LL) leprosy patients showed spontaneous apoptosis when cultured in the absence of mitogen for 24 h, which was inhibited by anti-tumour necrosis factor-alpha (TNF-alpha) antibodies. Apoptosis was also inhibited by ionomycin and zinc, which also increased IL-2 and decreased TNF-alpha production. The increase in IL-2 production suggests a mechanism whereby dietary supplements with zinc might alter the cell-mediated immunity response in leprosy patients.  (+info)

Antibodies to sulfatide in leprosy and leprosy reactions. (3/186)

Antibodies to sulfatide have been reported in various demyelinating peripheral polyneuropathies. We have investigated the diagnostic value of these antibodies in leprosy. Anti-sulfatide IgM in leprosy patients was not significantly elevated. High anti-sulfatide IgG titers were observed in individuals from endemic areas, irrespective of their leprosy status, while western European controls were negative. No significant correlation was found between IgM or IgG antibody titers and leprosy classification, although multibacillary patients had higher anti-sulfatide IgM titers than paucibacillary patients. In addition, 23 patients developing leprosy reactions were followed longitudinally. Antibody titers in these patients fluctuated slightly during the follow-up period. There was no association with the occurrence of leprosy reactions or treatment. Thus, IgG titers against sulfatides are high in both leprosy patients and healthy controls in endemic areas, whereas such antibodies are not found in western European controls, suggesting that these antibodies are induced by environmental factors, such as microorganisms.  (+info)

Differential representations of memory T cell subsets are characteristic of polarized immunity in leprosy and atopic diseases. (4/186)

We identified functionally polarized subsets of CD4 memory T cells on the basis of the expression of CD11a, CD45RA and CD62L. Within the several phenotypically distinct subsets of CD4 memory cells are two that, upon stimulation, produce primarily IL-4 (MT(2), CD45RA(-)CD62L(+)CD11a(dim)) or primarily IFN-gamma (MT(1), CD45RA(-)CD62L(-)CD11a(bright)). In addition, four other phenotypically distinct subsets of CD4 cells have unique cytokine profiles. To determine the clinical relevance of the representation of these cell types, we analyzed blood from patients with the chronic diseases leprosy and atopy. These diseases are characterized as immunologically polarized, since T cell responses in affected individuals are often strongly biased towards T(h)1 (dominated by IFN-gamma production) or T(h)2 (IL-4 production). We show here that this polarization reflects homeostatic or differentiation mechanisms affecting the representation of the functionally distinct subsets of memory CD4 T cells, MT(1) and MT(2). Significantly, the representation of the MT(1) and MT(2) subsets differs dramatically between subjects with tuberculoid leprosy (a T(h)1 disease), or lepromatous leprosy or atopic disease (T(h)2 diseases). However, there was no difference in the cytokine profiles of these or any of the other finely resolved CD4 subsets, when compared between individuals across all disease states. Thus, it is the representation of these subsets in peripheral blood that is diagnostic of the polarized state of the immune system.  (+info)

Granulomatous reaction to intradermal injection of lepromin (Mitsuda reaction) is linked to the human NRAMP1 gene in Vietnamese leprosy sibships. (5/186)

The Mitsuda test, which measures the specific immune response against intradermally injected lepromin, has a high prognostic value for susceptibility or resistance to the lepromatous form of leprosy. A sib-pair linkage analysis between the Mitsuda response and the NRAMP1 gene was done among 20 nuclear families with leprosy (totaling 118 sibs) from Ho Chi Minh City, Vietnam. All family subjects were genotyped for several intragenic and flanking NRAMP1 markers, leading to the definition of a fully informative NRAMP1 haplotype. Significant linkage was observed between NRAMP1 and Mitsuda reaction when considered either as a quantitative (P<.002) or as a categorical (P=.001) trait. Separate analyses among healthy and affected sibs showed evidence for linkage in both subsamples, indicating that linkage between the Mitsuda reaction and NRAMP1 is independent of leprosy status. These results support the view that NRAMP1 plays a regulatory role for the development of acquired antimycobacterial immune responses as determined by in vivo Mitsuda test reaction.  (+info)

Vasculitic neuropathy in a patient with inactive treated lepromatous leprosy. (6/186)

A 46 year old Asian male with previously treated lepromatous leprosy developed a stepwise multifocal sensory disturbance 25 years later. Neurophysiology demonstrated marked deterioration from previous studies. Sural nerve biopsy disclosed a vasculitic process superimposed on inactive lepromatous leprosy. Immunocytochemical stains for mycobacterial antigen showed deposits within nerve and vessel walls. A delayed vasculitic neuropathy precipitated by persisting mycobacterial antigen is proposed.  (+info)

A role for CD40-CD40 ligand interactions in the generation of type 1 cytokine responses in human leprosy. (7/186)

The interaction of CD40 ligand (CD40L) expressed by activated T cells with CD40 on macrophages has been shown to be a potent stimulus for the production of IL-12, an obligate signal for generation of Th1 cytokine responses. The expression and interaction of CD40 and CD40L were investigated in human infectious disease using leprosy as a model. CD40 and CD40L mRNA and surface protein expression were predominant in skin lesions of resistant tuberculoid patients compared with the highly susceptible lepromatous group. IL-12 release from PBMC of tuberculoid patients stimulated with Mycobacterium leprae was partially inhibited by mAbs to CD40 or CD40L, correlating with Ag-induced up-regulation of CD40L on T cells. Cognate recognition of M. leprae Ag by a T cell clone derived from a tuberculoid lesion in the context of monocyte APC resulted in CD40L-CD40-dependent production of IL-12. In contrast, M. leprae-induced IL-12 production by PBMC from lepromatous patients was not dependent on CD40L-CD40 ligation, nor was CD40L up-regulated by M. leprae. Furthermore, IL-10, a cytokine predominant in lepromatous lesions, blocked the IFN-gamma up-regulation of CD40 on monocytes. These data suggest that T cell activation in situ by M. leprae in tuberculoid leprosy leads to local up-regulation of CD40L, which stimulates CD40-dependent induction of IL-12 in monocytes. The CD40-CD40L interaction, which is not evident in lepromatous leprosy, probably participates in the cell-mediated immune response to microbial pathogens.  (+info)

Anti-inflammatory drugs block cytokine mRNA accumulation in the skin and improve the clinical condition of reactional leprosy patients. (8/186)

The aim of this study was to investigate in what ways in vivo anti-inflammatory treatment affects cytokine mRNA expression in situ in both erythema nodosum leprosum and reversal reaction patients. Serial biopsies were collected from the patients undergoing leprosy reactions before and during pentoxifylline (n = 7) or thalidomide (n = 3) treatment for erythema nodosum leprosum and prednisone (n = 3) for reversal reaction. Clinical evolution of the skin lesion was assessed during the study and semiquantitative reverse transcription-polymerase chain reaction was used to investigate cytokine mRNA expression at the lesion site. Results showed expression of interferon-gamma, interleukin-6, interleukin-10, interleukin-12 p40, and tumor necrosis factor-alpha in all patients tested at the onset of reactional episodes, but interleukin-4 mRNA was rarely detected in the lesions (n = 4). Follow-up analysis showed that, irrespective of the drugs used, tumor necrosis factor-alpha mRNA was diminished in 10 of the 13 patients tested. A concomitant decrease of mRNA accumulation was also observed for interferon-gamma (nine of 11 patients), interleukin-6 (nine of 11), and interleukin-12 p40 (six of eight). An inhibitory effect on interleukin-10 mRNA was likewise seen after thalidomide and pentoxifylline, but not subsequent to prednisone treatment. The data also demonstrated that cytokine mRNA inhibition correlates to the resolution of the inflammatory response in situ (n = 10), whereas the persistence/enhancement of cytokine message expression after treatment was associated with worsening of the skin condition, as seen in three erythema nodosum leprosum patients whose maintenance of local inflammation was accompanied by the appearance/persistence of interleukin-4 gene expression in situ subsequent to anti-inflammatory treatment. In summary, the participation of cytokines in leprosy inflammatory episodes seems to be directly associated with the patients' clinical evolution following therapy for reaction.  (+info)

Lepromatous leprosy is a type of leprosy, a chronic infectious disease caused by the bacterium Mycobacterium leprae. In this form of the disease, there is a widespread and diffuse involvement of the skin, mucous membranes, and peripheral nerves. The bacteria multiply slowly and spread to the skin, upper respiratory tract, and peripheral nerves.

In lepromatous leprosy, the immune response is weak, allowing for extensive bacterial multiplication and widespread tissue damage. The skin lesions are typically numerous, pale, and have a smooth surface. Nerve involvement can lead to loss of sensation, muscle weakness, and deformities, particularly in the hands and feet.

Lepromatous leprosy is a more severe form of the disease compared to tuberculoid leprosy, which has a stronger immune response and localized skin lesions. Both forms of the disease are treatable with multidrug therapy (MDT), recommended by the World Health Organization (WHO) for all leprosy patients. Early diagnosis and treatment can prevent disability and reduce transmission.

Leprosy, also known as Hansen's disease, is a chronic infectious disease caused by the bacterium Mycobacterium leprae. It primarily affects the skin, peripheral nerves, mucosal surfaces of the upper respiratory tract, and the eyes. The disease mainly spreads through droplets from the nose and mouth of infected people.

Leprosy is characterized by granulomatous inflammation, which leads to the formation of distinctive skin lesions and nerve damage. If left untreated, it can cause progressive and permanent damage to the skin, nerves, limbs, and eyes. However, with early diagnosis and multidrug therapy (MDT), the disease can be cured, and disability can be prevented or limited.

The World Health Organization (WHO) classifies leprosy into two types based on the number of skin lesions and bacteriological index: paucibacillary (one to five lesions) and multibacillary (more than five lesions). This classification helps determine the appropriate treatment regimen.

Although leprosy is curable, it remains a public health concern in many developing countries due to its stigmatizing nature and potential for social exclusion of affected individuals.

"Mycobacterium leprae" is a slow-growing, rod-shaped, gram-positive bacterium that is the causative agent of leprosy, a chronic infectious disease that primarily affects the skin, peripheral nerves, and mucosal surfaces of the upper respiratory tract. The bacterium was discovered in 1873 by Gerhard Armauer Hansen, a Norwegian physician, and is named after him as "Hansen's bacillus."

"Mycobacterium leprae" has a unique cell wall that contains high amounts of lipids, which makes it resistant to many common disinfectants and antibiotics. It can survive and multiply within host macrophages, allowing it to evade the immune system and establish a chronic infection.

Leprosy is a treatable disease with multidrug therapy (MDT), which combines several antibiotics such as dapsone, rifampicin, and clofazimine. Early diagnosis and treatment can prevent the progression of the disease and reduce its transmission to others.

Tuberculoid leprosy is a form of leprosy caused by the bacterium Mycobacterium leprae. It is one of the two major forms of the disease, with the other being lepromatous leprosy.

Tuberculoid leprosy typically presents with fewer lesions (generally less than five) that are well-defined, asymmetric, and dry. The lesions can be hypopigmented or erythematous and may have a raised border. Nerve involvement is common in tuberculoid leprosy, leading to symptoms such as numbness, muscle weakness, and paralysis.

The disease primarily affects the skin, peripheral nerves, and mucosa of the upper respiratory tract. Tuberculoid leprosy is characterized by a strong cell-mediated immune response, which can lead to the destruction of mycobacteria but may also cause tissue damage. It is generally a milder form of the disease compared to lepromatous leprosy and responds well to treatment with multidrug therapy (MDT).

"Borderline leprosy," also known as "borderline tuberculoid leprosy (BT)," is a type of leprosy that falls in the middle of the clinical spectrum of the disease. It has features of both tuberculoid and lepromatous leprosy, but they are not well-defined. The immune response in borderline leprosy is unstable, which means that the condition can either improve or deteriorate over time.

In borderline leprosy, there are usually a few well-defined lesions with some sensory loss. The bacteria are present in the skin and nerves, but they have not yet caused extensive damage. Treatment for borderline leprosy is similar to that of other forms of leprosy, which typically involves multidrug therapy (MDT) recommended by the World Health Organization (WHO).

It's important to note that leprosy is a curable disease, and early diagnosis and treatment can prevent complications and reduce transmission.

Erythema nodosum is a type of inflammation that occurs in the fatty layer of the skin, causing painful, red or purple bumps (nodules) to form. It is a type of panniculitis, which refers to any condition that causes inflammation of the fatty layer of tissue beneath the skin.

Erythema nodosum is often associated with a variety of underlying conditions, such as infections (e.g., streptococcus, tuberculosis), medications (e.g., sulfa drugs, oral contraceptives), inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis), and pregnancy.

The bumps associated with erythema nodosum typically appear on the shins, ankles, knees, or other areas of the legs, although they can also occur on the arms, hands, or face. The bumps may be tender to the touch, warm, and swollen, and they may cause pain or discomfort when walking or standing for prolonged periods.

In most cases, erythema nodosum resolves on its own within a few weeks to several months, although symptoms can be managed with medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids. Treating the underlying condition is also important for resolving erythema nodosum and preventing recurrences.

Leprosstatic agents are substances or drugs that have a specific effect on the bacterium that causes leprosy, also known as Mycobacterium leprae. These agents are used in the treatment and prevention of leprosy, a chronic infectious disease that primarily affects the skin, peripheral nerves, and mucosal surfaces of the upper respiratory tract.

The most common leprostatic agents are antibiotics, which target the bacterial cells and inhibit their growth or kill them. The two main antibiotics used to treat leprosy are dapsone and rifampicin, which are often given in combination with other drugs such as clofazimine to prevent the development of drug-resistant strains of the bacteria.

Leprosstatic agents are usually administered orally or by injection, and the duration of treatment can vary depending on the severity of the disease and the patient's response to therapy. It is important to note that early detection and treatment of leprosy can help prevent the progression of the disease and reduce the risk of transmission to others.

Lepromin is not a medical condition but rather a diagnostic test used in the diagnosis and classification of leprosy, a chronic infectious disease caused by the bacterium Mycobacterium leprae. The Lepromin test measures the cell-mediated immunity of an individual to the bacteria that causes leprosy.

The test involves injecting two types of antigens derived from M. leprae, one more soluble and the other less soluble, into the skin of the forearm. The response of the immune system to these antigens is then observed after 24 hours (for the soluble antigen) and 48 hours (for the less soluble antigen).

A positive reaction to the more soluble antigen indicates a strong cell-mediated immunity, which is associated with tuberculoid leprosy, a milder form of the disease. A positive reaction to the less soluble antigen suggests a weaker cell-mediated immunity and is associated with lepromatous leprosy, a more severe form of the disease.

It's important to note that the Lepromin test has limited availability and is not widely used in many parts of the world due to its complexity and the need for specialized laboratory facilities.

Multibacillary (MB) leprosy, also known as lepromatous leprosy, is a type of leprosy that is characterized by the widespread dissemination of the bacterium Mycobacterium leprae throughout the body. It is one of two major forms of leprosy, with the other being paucibacillary (PB) leprosy.

In MB leprosy, there are typically numerous skin lesions that may be widespread and often have a symmetrical distribution. The lesions can appear as nodules, plaques, or macules and can be hypopigmented or erythematous. They may also have a characteristic appearance with loss of sensation due to nerve damage.

MB leprosy is characterized by the presence of large numbers of bacilli in the skin lesions and nasal mucosa, as well as involvement of multiple nerves leading to deformities and disabilities if left untreated. The diagnosis of MB leprosy is usually made based on clinical examination, skin smears, and/or biopsy.

MB leprosy is treated with a multidrug therapy (MDT) regimen recommended by the World Health Organization (WHO), which includes rifampicin, dapsone, and clofazimine for at least 12 months. Early diagnosis and treatment of MB leprosy can prevent disability and reduce transmission.

Dapsone is a medication that belongs to a class of drugs called sulfones. It is primarily used to treat bacterial skin infections such as leprosy and dermatitis herpetiformis (a skin condition associated with coeliac disease). Dapsone works by killing the bacteria responsible for these infections.

In addition, dapsone has anti-inflammatory properties and is sometimes used off-label to manage inflammatory conditions such as vasculitis, bullous pemphigoid, and chronic urticaria. It is available in oral tablet form and topical cream or gel form.

Like all medications, dapsone can cause side effects, which may include nausea, loss of appetite, and headache. More serious side effects, such as methemoglobinemia (a blood disorder that affects the body's ability to transport oxygen), peripheral neuropathy (nerve damage that causes pain, numbness, or weakness in the hands and feet), and liver damage, can occur but are less common.

It is important for patients taking dapsone to be monitored by a healthcare provider to ensure safe and effective use of the medication.

An armadillo is not a medical condition or term. It is a type of mammal that is native to the Americas, known for its distinctive armor-like shell. If you have any questions about a specific medical condition or topic, I would be happy to help if you could provide more information.

Clofazimine is an antimycobacterial medication used mainly in the treatment of leprosy (Hansen's disease) and also has some activity against Mycobacterium avium complex (MAC) infections. It is an oral riminophenazine dye that accumulates in macrophages and bacterial cells, where it inhibits mycobacterial DNA-dependent RNA polymerase. Its side effects include skin discoloration, gastrointestinal symptoms, and potential eye toxicity.

Paucibacillary leprosy is a type of leprosy that is characterized by the presence of fewer than 5 skin lesions and no bacterial growth in slit skin smears or biopsies. It is also known as tuberculoid leprosy and is caused by the Mycobacterium leprae bacteria. The condition primarily affects the nerves and skin, leading to numbness, muscle weakness, and disfigurement if left untreated. Paucibacillary leprosy tends to have a better prognosis compared to multibacillary leprosy, which is characterized by more numerous skin lesions and bacterial growth.

Bacterial antigens are substances found on the surface or produced by bacteria that can stimulate an immune response in a host organism. These antigens can be proteins, polysaccharides, teichoic acids, lipopolysaccharides, or other molecules that are recognized as foreign by the host's immune system.

When a bacterial antigen is encountered by the host's immune system, it triggers a series of responses aimed at eliminating the bacteria and preventing infection. The host's immune system recognizes the antigen as foreign through the use of specialized receptors called pattern recognition receptors (PRRs), which are found on various immune cells such as macrophages, dendritic cells, and neutrophils.

Once a bacterial antigen is recognized by the host's immune system, it can stimulate both the innate and adaptive immune responses. The innate immune response involves the activation of inflammatory pathways, the recruitment of immune cells to the site of infection, and the production of antimicrobial peptides.

The adaptive immune response, on the other hand, involves the activation of T cells and B cells, which are specific to the bacterial antigen. These cells can recognize and remember the antigen, allowing for a more rapid and effective response upon subsequent exposures.

Bacterial antigens are important in the development of vaccines, as they can be used to stimulate an immune response without causing disease. By identifying specific bacterial antigens that are associated with virulence or pathogenicity, researchers can develop vaccines that target these antigens and provide protection against infection.

In medical terms, the skin is the largest organ of the human body. It consists of two main layers: the epidermis (outer layer) and dermis (inner layer), as well as accessory structures like hair follicles, sweat glands, and oil glands. The skin plays a crucial role in protecting us from external factors such as bacteria, viruses, and environmental hazards, while also regulating body temperature and enabling the sense of touch.

Glycolipids are a type of lipid (fat) molecule that contain one or more sugar molecules attached to them. They are important components of cell membranes, where they play a role in cell recognition and signaling. Glycolipids are also found on the surface of some viruses and bacteria, where they can be recognized by the immune system as foreign invaders.

There are several different types of glycolipids, including cerebrosides, gangliosides, and globosides. These molecules differ in the number and type of sugar molecules they contain, as well as the structure of their lipid tails. Glycolipids are synthesized in the endoplasmic reticulum and Golgi apparatus of cells, and they are transported to the cell membrane through vesicles.

Abnormalities in glycolipid metabolism or structure have been implicated in a number of diseases, including certain types of cancer, neurological disorders, and autoimmune diseases. For example, mutations in genes involved in the synthesis of glycolipids can lead to conditions such as Tay-Sachs disease and Gaucher's disease, which are characterized by the accumulation of abnormal glycolipids in cells.

Xenarthra is not a medical term, but a taxonomic category in biology. It refers to the order of mammals that consists of anteaters, sloths, and armadillos. These animals are characterized by their unique skeletal and dental structures, including extra joints between their vertebrae and specialized teeth for grinding or tearing food.

While Xenarthra is not a medical term, it is worth noting that these animals have some unique adaptations that can impact their health and veterinary care. For example, anteaters have an extremely long and sticky tongue to eat ants and termites, which can make dental care challenging. Sloths have a slow metabolism and spend most of their time hanging upside down in trees, which can affect their digestion and musculoskeletal health. Armadillos are known to be carriers of leprosy, which can impact human health in certain areas where they are common.

'Mycobacterium lepraemurium' is not typically associated with human leprosy or any medical conditions affecting humans. It is a species of mycobacteria that primarily infects rodents, particularly mice and rats. This bacterium is the causative agent of a form of leprosy-like disease in these animals, known as murine leprosy.

Human infections with 'Mycobacterium lepraemurium' are extremely rare and have only been reported in a handful of cases worldwide. When they do occur, they usually result from close contact with infected rodents or their excrement. The disease caused by this bacterium in humans is typically milder than human leprosy and often resolves on its own without specific treatment.

Therefore, 'Mycobacterium lepraemurium' should not be confused with the mycobacterial species that cause leprosy in humans, such as 'Mycobacterium leprae' or 'Mycobacterium lepromatosis'.

Bacterial antibodies are a type of antibodies produced by the immune system in response to an infection caused by bacteria. These antibodies are proteins that recognize and bind to specific antigens on the surface of the bacterial cells, marking them for destruction by other immune cells. Bacterial antibodies can be classified into several types based on their structure and function, including IgG, IgM, IgA, and IgE. They play a crucial role in the body's defense against bacterial infections and provide immunity to future infections with the same bacteria.

"Mycobacterium" is a genus of gram-positive, aerobic, rod-shaped bacteria that are characterized by their complex cell walls containing large amounts of lipids. This genus includes several species that are significant in human and animal health, most notably Mycobacterium tuberculosis, which causes tuberculosis, and Mycobacterium leprae, which causes leprosy. Other species of Mycobacterium can cause various diseases in humans, including skin and soft tissue infections, lung infections, and disseminated disease in immunocompromised individuals. These bacteria are often resistant to common disinfectants and antibiotics, making them difficult to treat.

A granuloma is a small, nodular inflammatory lesion that occurs in various tissues in response to chronic infection, foreign body reaction, or autoimmune conditions. Histologically, it is characterized by the presence of epithelioid macrophages, which are specialized immune cells with enlarged nuclei and abundant cytoplasm, often arranged in a palisading pattern around a central area containing necrotic debris, microorganisms, or foreign material.

Granulomas can be found in various medical conditions such as tuberculosis, sarcoidosis, fungal infections, and certain autoimmune disorders like Crohn's disease. The formation of granulomas is a complex process involving both innate and adaptive immune responses, which aim to contain and eliminate the offending agent while minimizing tissue damage.

Facial dermatoses refer to various skin conditions that affect the face. These can include a wide range of disorders, such as:

1. Acne vulgaris: A common skin condition characterized by the formation of comedones (blackheads and whiteheads) and inflammatory papules, pustules, and nodules. It primarily affects the face, neck, chest, and back.
2. Rosacea: A chronic skin condition that causes redness, flushing, and visible blood vessels on the face, along with bumps or pimples and sometimes eye irritation.
3. Seborrheic dermatitis: A common inflammatory skin disorder that causes a red, itchy, and flaky rash, often on the scalp, face, and eyebrows. It can also affect other oily areas of the body, like the sides of the nose and behind the ears.
4. Atopic dermatitis (eczema): A chronic inflammatory skin condition that causes red, itchy, and scaly patches on the skin. While it can occur anywhere on the body, it frequently affects the face, especially in infants and young children.
5. Psoriasis: An autoimmune disorder that results in thick, scaly, silvery, or red patches on the skin. It can affect any part of the body, including the face.
6. Contact dermatitis: A skin reaction caused by direct contact with an allergen or irritant, resulting in redness, itching, and inflammation. The face can be affected when allergens or irritants come into contact with the skin through cosmetics, skincare products, or other substances.
7. Lupus erythematosus: An autoimmune disorder that can cause a butterfly-shaped rash on the cheeks and nose, along with other symptoms like joint pain, fatigue, and photosensitivity.
8. Perioral dermatitis: A inflammatory skin condition that causes redness, small bumps, and dryness around the mouth, often mistaken for acne. It can also affect the skin around the nose and eyes.
9. Vitiligo: An autoimmune disorder that results in the loss of pigmentation in patches of skin, which can occur on the face and other parts of the body.
10. Tinea faciei: A fungal infection that affects the facial skin, causing red, scaly, or itchy patches. It is also known as ringworm of the face.

These are just a few examples of skin conditions that can affect the face. If you experience any unusual symptoms or changes in your skin, it's essential to consult a dermatologist for proper diagnosis and treatment.

Transfer factors are natural immune system components that are passed from one individual to another, usually through blood products. They are small proteins called cytokines that are secreted by certain white blood cells (T-lymphocytes or T-cells) and function to regulate the immune system's response to foreign substances.

Transfer factors can be extracted from human blood and given to individuals with weakened immune systems, such as those undergoing chemotherapy or suffering from immune deficiency disorders, to help enhance their immune response. They have also been used in the treatment of chronic fatigue syndrome, allergies, and certain viral infections.

It's important to note that while transfer factors have shown promise in some studies, more research is needed to fully understand their effectiveness and safety.

Prothionamide is an antimicrobial medication used primarily in the treatment of tuberculosis (TB). It's a second-line drug, which means it's used when first-line treatments aren't effective or if the strain of TB is resistant to other drugs.

Prothionamide is a bacteriostatic agent, meaning it inhibits the growth of Mycobacterium tuberculosis, the bacterium that causes TB, rather than killing it outright. It does this by interfering with the bacterium's ability to synthesize its cell wall.

Like many other medications used to treat TB, prothionamide is often used in combination therapy, where it's given alongside other antimicrobial drugs, to reduce the risk of the bacteria developing resistance to the treatment.

Please note that this definition is a general overview and may not include all the potential uses, precautions, side effects, and interactions related to this drug. Always consult with a healthcare professional for medical advice.

Lymphocyte activation is the process by which B-cells and T-cells (types of lymphocytes) become activated to perform effector functions in an immune response. This process involves the recognition of specific antigens presented on the surface of antigen-presenting cells, such as dendritic cells or macrophages.

The activation of B-cells leads to their differentiation into plasma cells that produce antibodies, while the activation of T-cells results in the production of cytotoxic T-cells (CD8+ T-cells) that can directly kill infected cells or helper T-cells (CD4+ T-cells) that assist other immune cells.

Lymphocyte activation involves a series of intracellular signaling events, including the binding of co-stimulatory molecules and the release of cytokines, which ultimately result in the expression of genes involved in cell proliferation, differentiation, and effector functions. The activation process is tightly regulated to prevent excessive or inappropriate immune responses that can lead to autoimmunity or chronic inflammation.

T-lymphocytes, also known as T-cells, are a type of white blood cell that plays a key role in the adaptive immune system's response to infection. They are produced in the bone marrow and mature in the thymus gland. There are several different types of T-cells, including CD4+ helper T-cells, CD8+ cytotoxic T-cells, and regulatory T-cells (Tregs).

CD4+ helper T-cells assist in activating other immune cells, such as B-lymphocytes and macrophages. They also produce cytokines, which are signaling molecules that help coordinate the immune response. CD8+ cytotoxic T-cells directly kill infected cells by releasing toxic substances. Regulatory T-cells help maintain immune tolerance and prevent autoimmune diseases by suppressing the activity of other immune cells.

T-lymphocytes are important in the immune response to viral infections, cancer, and other diseases. Dysfunction or depletion of T-cells can lead to immunodeficiency and increased susceptibility to infections. On the other hand, an overactive T-cell response can contribute to autoimmune diseases and chronic inflammation.

Skin tests are medical diagnostic procedures that involve the application of a small amount of a substance to the skin, usually through a scratch, prick, or injection, to determine if the body has an allergic reaction to it. The most common type of skin test is the patch test, which involves applying a patch containing a small amount of the suspected allergen to the skin and observing the area for signs of a reaction, such as redness, swelling, or itching, over a period of several days. Another type of skin test is the intradermal test, in which a small amount of the substance is injected just beneath the surface of the skin. Skin tests are used to help diagnose allergies, including those to pollen, mold, pets, and foods, as well as to identify sensitivities to medications, chemicals, and other substances.

Eye diseases are a range of conditions that affect the eye or visual system, causing damage to vision and, in some cases, leading to blindness. These diseases can be categorized into various types, including:

1. Refractive errors: These include myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia, which affect the way light is focused on the retina and can usually be corrected with glasses or contact lenses.
2. Cataracts: A clouding of the lens inside the eye that leads to blurry vision, glare, and decreased contrast sensitivity. Cataract surgery is the most common treatment for this condition.
3. Glaucoma: A group of diseases characterized by increased pressure in the eye, leading to damage to the optic nerve and potential blindness if left untreated. Treatment includes medications, laser therapy, or surgery.
4. Age-related macular degeneration (AMD): A progressive condition that affects the central part of the retina called the macula, causing blurry vision and, in advanced stages, loss of central vision. Treatment may include anti-VEGF injections, laser therapy, or nutritional supplements.
5. Diabetic retinopathy: A complication of diabetes that affects the blood vessels in the retina, leading to bleeding, leakage, and potential blindness if left untreated. Treatment includes laser therapy, anti-VEGF injections, or surgery.
6. Retinal detachment: A separation of the retina from its underlying tissue, which can lead to vision loss if not treated promptly with surgery.
7. Amblyopia (lazy eye): A condition where one eye does not develop normal vision, often due to a misalignment or refractive error in childhood. Treatment includes correcting the underlying problem and encouraging the use of the weaker eye through patching or other methods.
8. Strabismus (crossed eyes): A misalignment of the eyes that can lead to amblyopia if not treated promptly with surgery, glasses, or other methods.
9. Corneal diseases: Conditions that affect the transparent outer layer of the eye, such as keratoconus, Fuchs' dystrophy, and infectious keratitis, which can lead to vision loss if not treated promptly.
10. Uveitis: Inflammation of the middle layer of the eye, which can cause vision loss if not treated promptly with anti-inflammatory medications or surgery.

Rifampin is an antibiotic medication that belongs to the class of drugs known as rifamycins. It works by inhibiting bacterial DNA-dependent RNA polymerase, thereby preventing bacterial growth and multiplication. Rifampin is used to treat a variety of infections caused by bacteria, including tuberculosis, Haemophilus influenzae, Neisseria meningitidis, and Legionella pneumophila. It is also used to prevent meningococcal disease in people who have been exposed to the bacteria.

Rifampin is available in various forms, including tablets, capsules, and injectable solutions. The medication is usually taken two to four times a day, depending on the type and severity of the infection being treated. Rifampin may be given alone or in combination with other antibiotics.

It is important to note that rifampin can interact with several other medications, including oral contraceptives, anticoagulants, and anti-seizure drugs, among others. Therefore, it is essential to inform your healthcare provider about all the medications you are taking before starting treatment with rifampin.

Rifampin may cause side effects such as nausea, vomiting, diarrhea, dizziness, headache, and changes in the color of urine, tears, sweat, and saliva to a reddish-orange color. These side effects are usually mild and go away on their own. However, if they persist or become bothersome, it is important to consult your healthcare provider.

In summary, rifampin is an antibiotic medication used to treat various bacterial infections and prevent meningococcal disease. It works by inhibiting bacterial DNA-dependent RNA polymerase, preventing bacterial growth and multiplication. Rifampin may interact with several other medications, and it can cause side effects such as nausea, vomiting, diarrhea, dizziness, headache, and changes in the color of body fluids.

Cellular immunity, also known as cell-mediated immunity, is a type of immune response that involves the activation of immune cells, such as T lymphocytes (T cells), to protect the body against infected or damaged cells. This form of immunity is important for fighting off infections caused by viruses and intracellular bacteria, as well as for recognizing and destroying cancer cells.

Cellular immunity involves a complex series of interactions between various immune cells and molecules. When a pathogen infects a cell, the infected cell displays pieces of the pathogen on its surface in a process called antigen presentation. This attracts T cells, which recognize the antigens and become activated. Activated T cells then release cytokines, chemicals that help coordinate the immune response, and can directly attack and kill infected cells or help activate other immune cells to do so.

Cellular immunity is an important component of the adaptive immune system, which is able to learn and remember specific pathogens in order to mount a faster and more effective response upon subsequent exposure. This form of immunity is also critical for the rejection of transplanted organs, as the immune system recognizes the transplanted tissue as foreign and attacks it.

BCG (Bacillus Calmette-Guérin) vaccine is a type of immunization used primarily to prevent tuberculosis (TB). It contains a live but weakened strain of Mycobacterium bovis, which is related to the bacterium that causes TB in humans (Mycobacterium tuberculosis).

The BCG vaccine works by stimulating an immune response in the body, enabling it to better resist infection with TB bacteria if exposed in the future. It is often given to infants and children in countries where TB is common, and its use varies depending on the national immunization policies. The protection offered by the BCG vaccine is moderate and may not last for a very long time.

In addition to its use against TB, the BCG vaccine has also been investigated for its potential therapeutic role in treating bladder cancer and some other types of cancer. The mechanism of action in these cases is thought to be related to the vaccine's ability to stimulate an immune response against abnormal cells.

Peripheral nerves are nerve fibers that transmit signals between the central nervous system (CNS, consisting of the brain and spinal cord) and the rest of the body. These nerves convey motor, sensory, and autonomic information, enabling us to move, feel, and respond to changes in our environment. They form a complex network that extends from the CNS to muscles, glands, skin, and internal organs, allowing for coordinated responses and functions throughout the body. Damage or injury to peripheral nerves can result in various neurological symptoms, such as numbness, weakness, or pain, depending on the type and severity of the damage.

"Mycobacterium bovis" is a species of slow-growing, aerobic, gram-positive bacteria in the family Mycobacteriaceae. It is the causative agent of tuberculosis in cattle and other animals, and can also cause tuberculosis in humans, particularly in those who come into contact with infected animals or consume unpasteurized dairy products from infected cows. The bacteria are resistant to many common disinfectants and survive for long periods in a dormant state, making them difficult to eradicate from the environment. "Mycobacterium bovis" is closely related to "Mycobacterium tuberculosis," the bacterium that causes tuberculosis in humans, and both species share many genetic and biochemical characteristics.

Peripheral Nervous System (PNS) diseases, also known as Peripheral Neuropathies, refer to conditions that affect the functioning of the peripheral nervous system, which includes all the nerves outside the brain and spinal cord. These nerves transmit signals between the central nervous system (CNS) and the rest of the body, controlling sensations, movements, and automatic functions such as heart rate and digestion.

PNS diseases can be caused by various factors, including genetics, infections, toxins, metabolic disorders, trauma, or autoimmune conditions. The symptoms of PNS diseases depend on the type and extent of nerve damage but often include:

1. Numbness, tingling, or pain in the hands and feet
2. Muscle weakness or cramps
3. Loss of reflexes
4. Decreased sensation to touch, temperature, or vibration
5. Coordination problems and difficulty with balance
6. Sexual dysfunction
7. Digestive issues, such as constipation or diarrhea
8. Dizziness or fainting due to changes in blood pressure

Examples of PNS diseases include Guillain-Barre syndrome, Charcot-Marie-Tooth disease, diabetic neuropathy, and peripheral nerve injuries. Treatment for these conditions varies depending on the underlying cause but may involve medications, physical therapy, lifestyle changes, or surgery.

Phenazines are a class of heterocyclic aromatic organic compounds that consist of two nitrogen atoms connected by a five-membered ring. They are naturally occurring in various species of bacteria and fungi, where they play a role in chemical defense and communication. Some phenazines have been found to have antibiotic, antifungal, and antiparasitic properties. Synthetic phenazines are also used in various industrial applications, such as dyes and pigments, and as components in some pharmaceuticals and agrochemicals.

Suppressor factors, immunologic, refer to substances that can suppress or decrease the immune response. They were first described in the 1970s and are produced by certain cells of the immune system, such as T cells. Suppressor factors help to maintain immune homeostasis and prevent overactive immune responses that can lead to autoimmune diseases or chronic inflammation.

Immunologic suppressor factors can inhibit the activation and proliferation of various immune cells, including T cells, B cells, and natural killer (NK) cells. They can also suppress the production of cytokines, which are signaling molecules that help regulate the immune response. Suppressor factors have been studied in the context of various diseases, including cancer, autoimmune disorders, and transplant rejection.

However, the concept of immunologic suppressor factors has been controversial, and their precise mechanisms of action are not fully understood. Some researchers have questioned whether they truly exist as distinct entities or whether they represent a heterogeneous group of regulatory molecules with diverse functions. Nonetheless, the study of immunologic suppressor factors remains an active area of research, as understanding how they work could lead to new therapies for a variety of diseases.

I'm sorry for any confusion, but "India" is not a medical term or concept. It is a country in South Asia, the second-most populous country in the world, known for its rich history, diverse culture, and numerous contributions to various fields including medicine. If you have any questions related to medical topics, I would be happy to help answer them!

Interferon-gamma (IFN-γ) is a soluble cytokine that is primarily produced by the activation of natural killer (NK) cells and T lymphocytes, especially CD4+ Th1 cells and CD8+ cytotoxic T cells. It plays a crucial role in the regulation of the immune response against viral and intracellular bacterial infections, as well as tumor cells. IFN-γ has several functions, including activating macrophages to enhance their microbicidal activity, increasing the presentation of major histocompatibility complex (MHC) class I and II molecules on antigen-presenting cells, stimulating the proliferation and differentiation of T cells and NK cells, and inducing the production of other cytokines and chemokines. Additionally, IFN-γ has direct antiproliferative effects on certain types of tumor cells and can enhance the cytotoxic activity of immune cells against infected or malignant cells.

Delayed hypersensitivity, also known as type IV hypersensitivity, is a type of immune response that takes place several hours to days after exposure to an antigen. It is characterized by the activation of T cells (a type of white blood cell) and the release of various chemical mediators, leading to inflammation and tissue damage. This reaction is typically associated with chronic inflammatory diseases, such as contact dermatitis, granulomatous disorders (e.g. tuberculosis), and certain autoimmune diseases.

The reaction process involves the following steps:

1. Sensitization: The first time an individual is exposed to an antigen, T cells are activated and become sensitized to it. This process can take several days.
2. Memory: Some of the activated T cells differentiate into memory T cells, which remain in the body and are ready to respond quickly if the same antigen is encountered again.
3. Effector phase: Upon subsequent exposure to the antigen, the memory T cells become activated and release cytokines, which recruit other immune cells (e.g. macrophages) to the site of inflammation. These cells cause tissue damage through various mechanisms, such as phagocytosis, degranulation, and the release of reactive oxygen species.
4. Chronic inflammation: The ongoing immune response can lead to chronic inflammation, which may result in tissue destruction and fibrosis (scarring).

Examples of conditions associated with delayed hypersensitivity include:

* Contact dermatitis (e.g. poison ivy, nickel allergy)
* Tuberculosis
* Leprosy
* Sarcoidosis
* Rheumatoid arthritis
* Type 1 diabetes mellitus
* Multiple sclerosis
* Inflammatory bowel disease (e.g. Crohn's disease, ulcerative colitis)

Immunoglobulin G (IgG) is a type of antibody, which is a protective protein produced by the immune system in response to foreign substances like bacteria or viruses. IgG is the most abundant type of antibody in human blood, making up about 75-80% of all antibodies. It is found in all body fluids and plays a crucial role in fighting infections caused by bacteria, viruses, and toxins.

IgG has several important functions:

1. Neutralization: IgG can bind to the surface of bacteria or viruses, preventing them from attaching to and infecting human cells.
2. Opsonization: IgG coats the surface of pathogens, making them more recognizable and easier for immune cells like neutrophils and macrophages to phagocytose (engulf and destroy) them.
3. Complement activation: IgG can activate the complement system, a group of proteins that work together to help eliminate pathogens from the body. Activation of the complement system leads to the formation of the membrane attack complex, which creates holes in the cell membranes of bacteria, leading to their lysis (destruction).
4. Antibody-dependent cellular cytotoxicity (ADCC): IgG can bind to immune cells like natural killer (NK) cells and trigger them to release substances that cause target cells (such as virus-infected or cancerous cells) to undergo apoptosis (programmed cell death).
5. Immune complex formation: IgG can form immune complexes with antigens, which can then be removed from the body through various mechanisms, such as phagocytosis by immune cells or excretion in urine.

IgG is a critical component of adaptive immunity and provides long-lasting protection against reinfection with many pathogens. It has four subclasses (IgG1, IgG2, IgG3, and IgG4) that differ in their structure, function, and distribution in the body.

An Enzyme-Linked Immunosorbent Assay (ELISA) is a type of analytical biochemistry assay used to detect and quantify the presence of a substance, typically a protein or peptide, in a liquid sample. It takes its name from the enzyme-linked antibodies used in the assay.

In an ELISA, the sample is added to a well containing a surface that has been treated to capture the target substance. If the target substance is present in the sample, it will bind to the surface. Next, an enzyme-linked antibody specific to the target substance is added. This antibody will bind to the captured target substance if it is present. After washing away any unbound material, a substrate for the enzyme is added. If the enzyme is present due to its linkage to the antibody, it will catalyze a reaction that produces a detectable signal, such as a color change or fluorescence. The intensity of this signal is proportional to the amount of target substance present in the sample, allowing for quantification.

ELISAs are widely used in research and clinical settings to detect and measure various substances, including hormones, viruses, and bacteria. They offer high sensitivity, specificity, and reproducibility, making them a reliable choice for many applications.

Immunoglobulin M (IgM) is a type of antibody that is primarily found in the blood and lymph fluid. It is the first antibody to be produced in response to an initial exposure to an antigen, making it an important part of the body's primary immune response. IgM antibodies are large molecules that are composed of five basic units, giving them a pentameric structure. They are primarily found on the surface of B cells as membrane-bound immunoglobulins (mlgM), where they function as receptors for antigens. Once an mlgM receptor binds to an antigen, it triggers the activation and differentiation of the B cell into a plasma cell that produces and secretes large amounts of soluble IgM antibodies.

IgM antibodies are particularly effective at agglutination (clumping) and complement activation, which makes them important in the early stages of an immune response to help clear pathogens from the bloodstream. However, they are not as stable or long-lived as other types of antibodies, such as IgG, and their levels tend to decline after the initial immune response has occurred.

In summary, Immunoglobulin M (IgM) is a type of antibody that plays a crucial role in the primary immune response to antigens by agglutination and complement activation. It is primarily found in the blood and lymph fluid, and it is produced by B cells after they are activated by an antigen.

Monocytes are a type of white blood cell that are part of the immune system. They are large cells with a round or oval shape and a nucleus that is typically indented or horseshoe-shaped. Monocytes are produced in the bone marrow and then circulate in the bloodstream, where they can differentiate into other types of immune cells such as macrophages and dendritic cells.

Monocytes play an important role in the body's defense against infection and tissue damage. They are able to engulf and digest foreign particles, microorganisms, and dead or damaged cells, which helps to clear them from the body. Monocytes also produce cytokines, which are signaling molecules that help to coordinate the immune response.

Elevated levels of monocytes in the bloodstream can be a sign of an ongoing infection, inflammation, or other medical conditions such as cancer or autoimmune disorders.

'Mycobacterium tuberculosis' is a species of slow-growing, aerobic, gram-positive bacteria that demonstrates acid-fastness. It is the primary causative agent of tuberculosis (TB) in humans. This bacterium has a complex cell wall rich in lipids, including mycolic acids, which provides a hydrophobic barrier and makes it resistant to many conventional antibiotics. The ability of M. tuberculosis to survive within host macrophages and resist the immune response contributes to its pathogenicity and the difficulty in treating TB infections.

M. tuberculosis is typically transmitted through inhalation of infectious droplets containing the bacteria, which primarily targets the lungs but can spread to other parts of the body (extrapulmonary TB). The infection may result in a spectrum of clinical manifestations, ranging from latent TB infection (LTBI) to active disease. LTBI represents a dormant state where individuals are infected with M. tuberculosis but do not show symptoms and cannot transmit the bacteria. However, they remain at risk of developing active TB throughout their lifetime, especially if their immune system becomes compromised.

Effective prevention and control strategies for TB rely on early detection, treatment, and public health interventions to limit transmission. The current first-line treatments for drug-susceptible TB include a combination of isoniazid, rifampin, ethambutol, and pyrazinamide for at least six months. Multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains of M. tuberculosis present significant challenges in TB control and require more complex treatment regimens.

Mononuclear leukocytes are a type of white blood cells (leukocytes) that have a single, large nucleus. They include lymphocytes (B-cells, T-cells, and natural killer cells), monocytes, and dendritic cells. These cells play important roles in the body's immune system, including defending against infection and disease, and participating in immune responses and surveillance. Mononuclear leukocytes can be found in the bloodstream as well as in tissues throughout the body. They are involved in both innate and adaptive immunity, providing specific and nonspecific defense mechanisms to protect the body from harmful pathogens and other threats.

Concanavalin A (Con A) is a type of protein known as a lectin, which is found in the seeds of the plant Canavalia ensiformis, also known as jack bean. It is often used in laboratory settings as a tool to study various biological processes, such as cell division and the immune response, due to its ability to bind specifically to certain sugars on the surface of cells. Con A has been extensively studied for its potential applications in medicine, including as a possible treatment for cancer and viral infections. However, more research is needed before these potential uses can be realized.
