Endothelial cell nitric oxide production in acute chest syndrome. (1/62)

Acute chest syndrome (ACS) is the most common form of acute pulmonary disease associated with sickle cell disease. To investigate the possibility that alterations in endothelial cell (EC) production and metabolism of nitric oxide (NO) products might be contributory, we measured NO products from cultured pulmonary EC exposed to red blood cells and/or plasma from sickle cell patients during crisis. Exposure to plasma from patients with ACS caused a 5- to 10-fold increase in S-nitrosothiol (RSNO) and a 7- to 14-fold increase in total nitrogen oxide (NO(x)) production by both pulmonary arterial and microvascular EC. Increases occurred within 2 h of exposure to plasma in a concentration-dependent manner and were associated with increases in endothelial nitric oxide synthase (eNOS) protein and eNOS enzymatic activity, but not with changes in nitric oxide synthase (NOS) III or NOS II transcripts, inducible NOS (iNOS) protein nor iNOS enzymatic activity. RSNO and NO(x) increased whether plasma was obtained from patients with ACS or other forms of vasoocclusive crisis. Furthermore, an oxidative state occurred and oxidative metabolites of NO, particularly peroxynitrite, were produced. These findings suggest that altered NO production and metabolism to damaging oxidative molecules contribute to the pathogenesis of ACS.  (+info)

An in vitro system for efficiently evaluating gene therapy approaches to hemoglobinopathies. (2/62)

A variety of gene therapy strategies are under development for the treatment of sickle cell anemia and other hemoglobinopathies. A number of alternative vectors have been developed to transfer and express the beta-globin gene and other therapeutic molecules, but none has resulted in efficient transduction and stable long-term expression in primary hematopoietic cells. One reason for this problem is that most vectors are initially evaluated in immortalized cell lines which may not faithfully recapitulate the biology of primary erythroid cells. In order to provide a more relevant system for efficiently evaluating alternative vector constructs for beta-globin disorders, we have developed (1) a simple method for generating primary human red blood cell (RBC) precursors in liquid culture established with mononuclear cells obtained from normal donors as well as patients with Hb SC disease; (2) a high titer retroviral vector which can be easily modified to optimize gene transfer and transgene expression; and (3) methods for transducing the RBC precursors at high efficiency. The development of simple and efficient methods and reagents for generating and transducing primary human RBC precursors provides a facile and effective means for screening alternative gene therapy strategies.

Helicobacter pylori infection in sickle cell disease. (3/62)

Abdominal pain is a common presenting symptom in adults with sickle cell disease (SCD). One case of Helicobacter pylori gastritis has been reported in a child with sickle cell anemia. H. pylori-induced peptic ulcer disease (PUD) has not previously been reported in adults with SCD. We report eight cases of H. pylori infection in adult sickle cell patients presenting with acute or recurrent abdominal pain and/or gastrointestinal bleeding. In all cases, H. pylori serology (IgG) was positive, and three patients had gastric or duodenal ulcer by endoscopic examination. All patients responded to H. pylori treatment with complete resolution of symptoms by 4 weeks. The prevalence of H. pylori infection in SCD is unknown, but patients may be at increased risk for H. pylori-induced PUD and complications due to pre-existing anemia, increased nonsteroidal anti-inflammatory drug use, and alloimmunization which may delay necessary transfusion. It is important that the differential diagnosis of abdominal pain in adults with SCD include nonsickle cell-related disorders such as PUD. When confirmed, a definitive etiology of PUD must be determined so that appropriate treatment strategies can be initiated promptly and excess morbidity avoided.  (+info)

Sickle cell disease and age at menarche in Jamaican girls: observations from a cohort study. (4/62)

AIMS: (1) To investigate the distribution of age at menarche in a representative sample of 99 patients with homozygous sickle cell (SS) disease, 69 with sickle cell haemoglobin C (SC) disease, and 100 controls with a normal haemoglobin (AA) genotype followed in a cohort study from birth. (2) To explore the determinants of the age at menarche. METHODS: Children ascertained in a newborn screening programme were followed prospectively from birth to age 18-26.5 years with regular assessments of height, weight, pubertal stage, and haematological indices at the Sickle Cell Clinic of the University Hospital of the West Indies. RESULTS: All subjects have now reached menarche and the mean age in normal controls (13.0 years) was significantly earlier than in SC disease (13.5 years) or SS disease (15.4 years). Greater weight and earlier age at menarche was the only association significant across all genotypes although additional contributions occurred from fetal haemoglobin and red cell count in SS disease. Alpha thalassaemia, which ameliorates many of the effects of SS disease, had no discernible effect on menarche. CONCLUSIONS: Mean age at menarche is delayed by 0.5 years in SC disease and by 2.4 years in SS disease. Weight appears to be the principle determinant of age at menarche.  (+info)

Oral citrulline as arginine precursor may be beneficial in sickle cell disease: early phase two results. (5/62)

L-Arginine may be a conditionally essential amino acid in children and adolescents with sickle cell disease, particularly as required substrate in the arginine-nitric oxide pathway for endogenous nitrovasodilation and vasoprotection. Vasoprotection by arginine is mediated partly by nitric oxide-induced inhibition of endothelial damage and inhibition of adhesion and activation of leukocytes. Activated leukocytes may trigger many of the complications, including vasoocclusive events and intimal hyperplasias. High blood leukocyte counts during steady states in the absence of infection are significant laboratory risk factors for adverse complications. L-Citrulline as precursor amino acid was given orally twice daily in daily doses of approximately 0.1 g/kg in a pilot Phase II clinical trial during steady states in four homozygous sickle cell disease subjects and one sickle cell-hemoglobin C disease patient (ages 10-18). There soon resulted dramatic improvements in symptoms of well-being, raised plasma arginine levels, and reductions in high total leukocyte and high segmented neutrophil counts toward or to within normal limits. Continued L-citrulline supplementation in compliant subjects continued to lessen symptomatology, to maintain plasma arginine concentrations greater than control levels, and to maintain nearly normal total leukocyte and neutrophil counts. Side effects or toxicity from citrulline were not experienced. Oral L-citrulline may portend very useful for palliative therapy in sickle cell disease. Placebo-controlled, long-term trials are now indicated.  (+info)

Neurocognitive development of young children with sickle cell disease through three years of age. (6/62)

OBJECTIVE: To determine (1) the neurocognitive development of children with sickle cell disease (SCD) from 6 months through 36 months of age, (2) the independent and combined contributions of biomedical risk and parenting risk to child neurocognitive functioning, and (3) the independent and combined contributions of biomedical risk, parent cognitive processes, and family functioning to parent adjustment. METHOD: The study sample included 89 African American children and their parents served through the Duke University-University of North Carolina Comprehensive Sickle Cell Center. Measures of cognitive and psychomotor development were obtained at 6, 12, 24, and 36 months of age, and parents completed self-report measures of the cognitive processes of daily stress and attributional style, psychological adjustment, and family functioning. RESULTS: There was no significant decrease in psychomotor functioning (PDI) over time but cognitive functioning (MDI) declined, with a significant decrease occurring between the 12- and 24-month assessment points. At 24 months, poorer cognitive functioning was associated with parenting risk, in terms of a learned-helplessness attributional style, and biomedical risk, in terms of HbSS phenotype. Levels of psychological distress within the clinical range were reported by 24% of the parents, and poorer parent adjustment was associated with high levels of daily stress, less knowledge about child development, lower expectations of efficacy, and HbSC phenotype. CONCLUSIONS: The findings indicate that young children with SCD are at risk for neurocognitive impairment and provide support for the initiation of early intervention studies to promote neurocognitive development.  (+info)

A human embryonic hemoglobin inhibits Hb S polymerization in vitro and restores a normal phenotype to mouse models of sickle cell disease. (7/62)

The principle that developmentally silenced globin genes can be reactivated in adults with defects in beta-globin gene expression has been well established both in vitro and in vivo. In practice, levels of developmental stage-discordant fetal gamma globin that can be achieved by using currently approved therapies are generally insufficient to fully resolve typical clincopathological features of sickle cell disease. The therapeutic potential of another developmentally silenced globin--embryonic epsilon globin--has been difficult to evaluate in the absence of a convenient expression system or an appropriate experimental model. The current work analyzes the antisickling properties of an epsilon -globin-containing heterotetramer (Hb Gower-2) both in vitro as well as in vivo in a well-established mouse model of sickle cell anemia. These animals, expressing 100% human Hb S, display a chronic hemolytic anemia with compensatory marrow and extramedullary erythropoiesis, abundant circulating sickled erythrocytes, and chronic tissue damage evidenced by parallel histopathological and functional deficits. By comparison, related mice that coexpress Hb S as well as Hb Gower-2 exhibit normal physiological, morphological, histological, and functional attributes. Subsequent in vitro analyses substantiate results from whole-animal studies, indicating that the polymerization of deoxygenated Hb S can be significantly slowed by relatively small quantities of Hb Gower-2. Together, the in vivo and in vitro analyses suggest that reactivation of epsilon-globin gene expression would be therapeutically beneficial to adults with sickle phenotypes, and provide a rationale for detailed investigations into the molecular basis for its developmental silencing.  (+info)

The effect of hydroxyurea on vasculopathy in a child with sickle cell disease. (8/62)

We report serial CNS findings in a girl with sickle cell disease and stroke. Religious considerations precluded transfusion and bone marrow transplantation; therefore, she received single-agent hydroxyurea therapy for almost 6 years. MR angiography showed that vascular patency improved, although diffuse cerebral atrophy slowly worsened. Hydroxyurea can be effective in treating vasculopathy, but it might not prevent the progression of parenchymal damage in advanced disease.  (+info)

Hemoglobin SC disease, also known as sickle cell-C disease or SC disorder, is a genetic blood disorder that is a variant of sickle cell anemia. It is caused by the presence of both hemoglobin S (HbS) and hemoglobin C (HbC) in the red blood cells.

Hemoglobin is the protein in red blood cells that carries oxygen throughout the body. In Hemoglobin SC disease, the abnormal HbS and HbC proteins can cause the red blood cells to become rigid, sticky, and C-shaped (sickled), which can lead to blockages in small blood vessels.

Symptoms of Hemoglibin SC disease may include anemia, fatigue, jaundice, episodes of pain (known as sickle cell crises), and an increased risk of infection. The severity of the symptoms can vary widely from person to person. Treatment typically focuses on managing symptoms and preventing complications, and may include medications, blood transfusions, and sometimes a bone marrow transplant.

Hemoglobin C is a type of hemoglobin variant, which is the oxygen-carrying protein in red blood cells. Hemoglobin C is caused by a specific genetic mutation that results in the substitution of lysine for glutamic acid at position 6 on the beta globin chain of the hemoglobin molecule.

This variant is often associated with a benign condition known as hemoglobin C trait, where an individual inherits one copy of the mutated gene from one parent and one normal gene from the other parent. People with this trait usually have no symptoms or only mild anemia, if any. However, if an individual inherits two copies of the Hemoglobin C gene (one from each parent), they will have a more severe form of hemoglobin disorder called Hemoglobin CC disease, which can cause mild to moderate hemolytic anemia and other complications.

It's important to note that Hemoglobin C is most commonly found in people of West African descent, but it can also occur in other populations with African ancestry.

Hemoglobin C disease is a genetic disorder that affects the structure and function of hemoglobin, a protein in red blood cells responsible for carrying oxygen throughout the body. The disease is caused by a mutation in the gene that produces the beta-globin chain of hemoglobin, resulting in the production of an abnormal form of hemoglobin called Hemoglobin C (HbC).

People with Hemoglobin C disease inherit one copy of the HbC gene from each parent. This means they have two copies of the mutated gene and produce mostly Hemoglobin C, instead of the normal Hemoglobin A. The presence of Hemoglobin C can cause the red blood cells to become rigid and fragile, leading to a condition called hemolytic anemia.

Symptoms of Hemoglobin C disease may include fatigue, weakness, shortness of breath, pale skin, jaundice, and dark urine. The severity of the symptoms can vary widely from person to person, with some individuals experiencing mild symptoms and others having more severe complications.

Hemoglobin C disease is a chronic condition that requires ongoing medical management, including regular monitoring of hemoglobin levels, iron status, and other blood parameters. Treatment may include blood transfusions, folic acid supplementation, and medications to manage symptoms such as anemia and pain.

It's important to note that Hemoglobin C disease is not the same as sickle cell disease, which is another genetic disorder that affects hemoglobin structure and function. While both conditions can cause hemolytic anemia, they are caused by different mutations in the beta-globin gene and have distinct clinical features and management approaches.

Abnormal erythrocytes refer to red blood cells that have an abnormal shape, size, or other characteristics. This can include various types of abnormalities such as:

1. Anisocytosis: Variation in the size of erythrocytes.
2. Poikilocytosis: Variation in the shape of erythrocytes, including but not limited to teardrop-shaped cells (dacrocytes), crescent-shaped cells (sickle cells), and spherical cells (spherocytes).
3. Anemia: A decrease in the total number of erythrocytes or a reduction in hemoglobin concentration, which can result from various underlying conditions such as iron deficiency, chronic disease, or blood loss.
4. Hemoglobinopathies: Abnormalities in the structure or function of hemoglobin, the protein responsible for carrying oxygen in erythrocytes, such as sickle cell anemia and thalassemia.
5. Inclusion bodies: Abnormal structures within erythrocytes, such as Heinz bodies (denatured hemoglobin) or Howell-Jolly bodies (nuclear remnants).

These abnormalities can be detected through a complete blood count (CBC) and peripheral blood smear examination. The presence of abnormal erythrocytes may indicate an underlying medical condition, and further evaluation is often necessary to determine the cause and appropriate treatment.

Sickle cell anemia is a genetic disorder that affects the hemoglobin in red blood cells. Hemoglobin is responsible for carrying oxygen throughout the body. In sickle cell anemia, the hemoglobin is abnormal and causes the red blood cells to take on a sickle shape, rather than the normal disc shape. These sickled cells are stiff and sticky, and they can block blood vessels, causing tissue damage and pain. They also die more quickly than normal red blood cells, leading to anemia.

People with sickle cell anemia often experience fatigue, chronic pain, and jaundice. They may also have a higher risk of infections and complications such as stroke, acute chest syndrome, and priapism. The disease is inherited from both parents, who must both be carriers of the sickle cell gene. It primarily affects people of African descent, but it can also affect people from other ethnic backgrounds.

There is no cure for sickle cell anemia, but treatments such as blood transfusions, medications to manage pain and prevent complications, and bone marrow transplantation can help improve quality of life for affected individuals. Regular medical care and monitoring are essential for managing the disease effectively.

Hemoglobin (Hb or Hgb) is the main oxygen-carrying protein in the red blood cells, which are responsible for delivering oxygen throughout the body. It is a complex molecule made up of four globin proteins and four heme groups. Each heme group contains an iron atom that binds to one molecule of oxygen. Hemoglobin plays a crucial role in the transport of oxygen from the lungs to the body's tissues, and also helps to carry carbon dioxide back to the lungs for exhalation.

There are several types of hemoglobin present in the human body, including:

* Hemoglobin A (HbA): This is the most common type of hemoglobin, making up about 95-98% of total hemoglobin in adults. It consists of two alpha and two beta globin chains.
* Hemoglobin A2 (HbA2): This makes up about 1.5-3.5% of total hemoglobin in adults. It consists of two alpha and two delta globin chains.
* Hemoglobin F (HbF): This is the main type of hemoglobin present in fetal life, but it persists at low levels in adults. It consists of two alpha and two gamma globin chains.
* Hemoglobin S (HbS): This is an abnormal form of hemoglobin that can cause sickle cell disease when it occurs in the homozygous state (i.e., both copies of the gene are affected). It results from a single amino acid substitution in the beta globin chain.
* Hemoglobin C (HbC): This is another abnormal form of hemoglobin that can cause mild to moderate hemolytic anemia when it occurs in the homozygous state. It results from a different single amino acid substitution in the beta globin chain than HbS.

Abnormal forms of hemoglobin, such as HbS and HbC, can lead to various clinical disorders, including sickle cell disease, thalassemia, and other hemoglobinopathies.

Erythrocyte deformability refers to the ability of red blood cells (erythrocytes) to change shape and bend without rupturing, which is crucial for their efficient movement through narrow blood vessels. This deformability is influenced by several factors including the cell membrane structure, hemoglobin concentration, and intracellular viscosity. A decrease in erythrocyte deformability can negatively impact blood flow and oxygen delivery to tissues, potentially contributing to various pathological conditions such as sickle cell disease, diabetes, and cardiovascular diseases.

The Mononuclear Phagocyte System (MPS) is a network of specialized immune cells distributed throughout the body, primarily consisting of monocytes, macrophages, and dendritic cells. These cells share a common bone marrow-derived precursor and play crucial roles in innate and adaptive immunity. They are involved in various functions such as:

1. Phagocytosis: engulfing and destroying foreign particles, microbes, and cellular debris.
2. Antigen presentation: processing and presenting antigens to T-cells to initiate an adaptive immune response.
3. Cytokine production: releasing pro- and anti-inflammatory cytokines to regulate immune responses and maintain tissue homeostasis.
4. Immune regulation: modulating the activity of other immune cells, including T-cells, B-cells, and natural killer (NK) cells.

The MPS is essential for maintaining tissue integrity, fighting infections, and orchestrating immune responses. Its components are found in various tissues, including the liver (Kupffer cells), spleen, lymph nodes, bone marrow, and connective tissues.

The conjunctiva is the mucous membrane that lines the inner surface of the eyelids and covers the front part of the eye, also known as the sclera. It helps to keep the eye moist and protected from irritants. The conjunctiva can become inflamed or infected, leading to conditions such as conjunctivitis (pink eye).

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

I'm sorry for any confusion, but "holography" is not a term that has a medical definition. Holography is a technique used to create 3D images, typically using laser light. It is commonly used in non-medical fields such as data storage, art, and security features on credit cards and banknotes. I'm here to help with medical information, so please feel free to ask me about any medical topics or questions you might have!

Microcirculation is the circulation of blood in the smallest blood vessels, including arterioles, venules, and capillaries. It's responsible for the delivery of oxygen and nutrients to the tissues and the removal of waste products. The microcirculation plays a crucial role in maintaining tissue homeostasis and is regulated by various physiological mechanisms such as autonomic nervous system activity, local metabolic factors, and hormones.

Impairment of microcirculation can lead to tissue hypoxia, inflammation, and organ dysfunction, which are common features in several diseases, including diabetes, hypertension, sepsis, and ischemia-reperfusion injury. Therefore, understanding the structure and function of the microcirculation is essential for developing new therapeutic strategies to treat these conditions.

In the context of medical terminology, "lenses" generally refers to optical lenses used in various medical devices and instruments. These lenses are typically made of glass or plastic and are designed to refract (bend) light in specific ways to help magnify, focus, or redirect images. Here are some examples:

1. In ophthalmology and optometry, lenses are used in eyeglasses, contact lenses, and ophthalmic instruments to correct vision problems like myopia (nearsightedness), hypermetropia (farsightedness), astigmatism, or presbyopia.
2. In surgical microscopes, lenses are used to provide a magnified and clear view of the operating field during microsurgical procedures like ophthalmic, neurosurgical, or ENT (Ear, Nose, Throat) surgeries.
3. In endoscopes and laparoscopes, lenses are used to transmit light and images from inside the body during minimally invasive surgical procedures.
4. In ophthalmic diagnostic instruments like slit lamps, lenses are used to examine various structures of the eye in detail.

In summary, "lenses" in medical terminology refer to optical components that help manipulate light to aid in diagnosis, treatment, or visual correction.

Pulse oximetry is a noninvasive method for monitoring a person's oxygen saturation (SO2) and pulse rate. It uses a device called a pulse oximeter, which measures the amount of oxygen-carrying hemoglobin in the blood compared to the amount of hemoglobin that is not carrying oxygen. This measurement is expressed as a percentage, known as oxygen saturation (SpO2). Normal oxygen saturation levels are generally 95% or above at sea level. Lower levels may indicate hypoxemia, a condition where there is not enough oxygen in the blood to meet the body's needs. Pulse oximetry is commonly used in hospitals and other healthcare settings to monitor patients during surgery, in intensive care units, and in sleep studies to detect conditions such as sleep apnea. It can also be used by individuals with certain medical conditions, such as chronic obstructive pulmonary disease (COPD), to monitor their oxygen levels at home.

Conjunctival diseases refer to a group of medical conditions that affect the conjunctiva, which is the thin, clear mucous membrane that covers the inner surface of the eyelids and the white part of the eye (known as the sclera). The conjunctiva helps to keep the eye moist and protected from irritants.

Conjunctival diseases can cause a range of symptoms, including redness, itching, burning, discharge, grittiness, and pain. Some common conjunctival diseases include:

1. Conjunctivitis (pink eye): This is an inflammation or infection of the conjunctiva that can be caused by viruses, bacteria, or allergies. Symptoms may include redness, itching, discharge, and watery eyes.
2. Pinguecula: This is a yellowish, raised bump that forms on the conjunctiva, usually near the corner of the eye. It is caused by an overgrowth of connective tissue and may be related to sun exposure or dry eye.
3. Pterygium: This is a fleshy growth that extends from the conjunctiva onto the cornea (the clear front part of the eye). It can cause redness, irritation, and vision problems if it grows large enough to cover the pupil.
4. Allergic conjunctivitis: This is an inflammation of the conjunctiva caused by an allergic reaction to substances such as pollen, dust mites, or pet dander. Symptoms may include redness, itching, watery eyes, and swelling.
5. Chemical conjunctivitis: This is an irritation or inflammation of the conjunctiva caused by exposure to chemicals such as chlorine, smoke, or fumes. Symptoms may include redness, burning, and tearing.
6. Giant papillary conjunctivitis (GPC): This is a type of allergic reaction that occurs in response to the presence of a foreign body in the eye, such as a contact lens. Symptoms may include itching, mucus discharge, and a gritty feeling in the eye.

Treatment for conjunctival diseases depends on the underlying cause. In some cases, over-the-counter medications or home remedies may be sufficient to relieve symptoms. However, more severe cases may require prescription medication or medical intervention. It is important to consult with a healthcare provider if you experience persistent or worsening symptoms of conjunctival disease.
