A delayed hypersensitivity involving the reaction between sunlight or other radiant energy source and a chemical substance to which the individual has been previously exposed and sensitized. It manifests as a papulovesicular, eczematous, or exudative dermatitis occurring chiefly on the light-exposed areas of the skin.
A nonimmunologic, chemically induced type of photosensitivity producing a sometimes vesiculating dermatitis. It results in hyperpigmentation and desquamation of the light-exposed areas of the skin.
A chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. It is manifested by lichenification, excoriation, and crusting, mainly on the flexural surfaces of the elbow and knee. In infants it is known as infantile eczema.
Any inflammation of the skin.
A contact dermatitis due to allergic sensitization to various substances. These substances subsequently produce inflammatory reactions in the skin of those who have acquired hypersensitivity to them as a result of prior exposure.

Interferon-gamma is involved in photoimmunoprotection by UVA (320-400 nm) radiation in mice. (1/26)

Ultraviolet B radiation not only inflicts tumor-initiating DNA damage, but also impairs T cell-mediated immunity relevant to survival of the initiated cells. We have reported, however, that ultraviolet A radiation, in contrast, is immunologically innocuous in hairless mice and opossums, but renders the animals resistant to the immunosuppression by ultraviolet B, or its mediator cis-urocanic acid. Ultraviolet B irradiation of skin causes abundant release of numerous cytokines (interleukin-1, interleukin-6, interleukin-10, tumor necrosis factor-alpha); notably interleukin-12 and interferon-gamma do not appear to be upregulated. A recent report has indicated that interleukin-12 protects from photoimmunosuppression in mice, but it remains unclear whether interleukin-12 acts directly or via interferon-gamma, which it is known to stimulate. Here we investigate the possible role of interferon-gamma in UVA photoimmunoprotection, using interferon-gamma gene knockout mice in comparison with control C57/BL6 mice, and the systemic contact hypersensitivity reaction (induced by sensitization through a nonirradiated skin site) to measure immunity. interferon-gamma-/- mice raised normal contact hypersensitivity responses, and were unaffected, as were C57BL control mice, by ultraviolet A exposure. In response to ultraviolet B irradiation or topical cis-urocanic acid treatment, control mice became immunosuppressed by 69% and 27%, respectively, and interferon-gamma-/- mice by 79% and 27%. When ultraviolet B exposure or cis-urocanic acid was followed by ultraviolet A irradiation, however, contact hypersensitivity was totally restored in control mice, but remained suppressed by 55% and 25%, respectively, in interferon-gamma-/- mice. Injection of recombinant interferon-gamma in the interferon-gamma-/- mice restored the ultraviolet A protective effect against cis-urocanic acid-induced immunosuppression. These observations suggest that interferon-gamma plays a part in ultraviolet A immunoprotection from the suppressive effect of ultraviolet B radiation and, and that the mechanism appears to be via antagonism by this cytokine of the cis-urocanic acid immunosuppressive action.  (+info)

Phytophotodermatitis associated with parsnip picking. (2/26)

Phytophotodermatitis to certain plant groups is a well recognised entity. The combination of sunlight exposure and contact with plants of the umbelliferae family leads to the development of painful, erythematous, and bullous lesions and later to cutaneous hyperpigmentation. Agricultural workers and many clinicians often fail to make this link when patients present with these lesions. An incident involving 11 patients is presented to high-light this problem.  (+info)

Formation of antigenic quinolone photoadducts on Langerhans cells initiates photoallergy to systemically administered quinolone in mice. (3/26)

Quinolone antibacterial agents are well known to cause photoallergy as a side-effect. Murine photoallergy to fluoroquinolones is a T cell-mediated immune response, evoked either by systemic fluoroquinolone and subsequent exposure of skin to ultraviolet A light or by subcutaneous injection of fluoroquinolone-photomodified epidermal cells. In this photosensitivity, epidermal Langerhans cells may be photomodified initially with the drug and thus present photohaptenic moieties to sensitize and restimulate T cells. Although we have shown that Langerhans cells photocoupled in vitro with fluoroquinolones are capable of stimulating sensitized T cells, it remains unclear whether systemically given fluoroquinolone photomodifies Langerhans cells upon ultraviolet A irradiation of the skin and the Langerhans cells become photohapten-bearing, T cell-stimulatory cells. In a murine model of fleroxacin photoallergy induced by intraperitoneal injection of the drugs plus ultraviolet A irradiation of skin, we found that Langerhans cells as well as keratinocytes are photoderivatized with fleroxacin as demonstrated with a fluoroquinolone-specific monoclonal antibody. Langerhans-cell-enriched epidermal cells prepared from mice treated with fleroxacin and ultraviolet A induced proliferation of sensitized T cells, indicating that photomodified Langerhans cells are functional. There was an optimal range of ultraviolet A dose to quantitatively and qualitatively form fleroxacin-photomodified Langerhans cells, as excess ultraviolet A rather reduced the photoantigen-presenting capacity of Langerhans cells presumably because of drug phototoxicity. Our study suggests that Langerhans cells serve as photoantigen-presenting cells in drug photoallergy.  (+info)

Quinolone-photoconjugated major histocompatibility complex class II-binding peptides with lysine are antigenic for T cells mediating murine quinolone photoallergy. (4/26)

Fluoroquinolone antibacterial agents cause photosensitivity dermatitis as an adverse effect and can function immunologically as photohapten. In a murine model of quinolone photoallergy, Langerhans cells are photomodified with a systemically given quinolone upon ultraviolet A irradiation of skin and thus present photohaptenic moieties to sensitize and restimulate T cells. The aim of this study is to determine the site of peptides/proteins photobound to quinolones and to assess the T cell antigenicity of quinolone-photocoupled peptides using Langerhans cells as photoadduct-presenting cells. On an amino acid composition analysis, lysine was preferentially degraded in bovine serum albumin that was ultraviolet A-conjugated with a representative quinolone ofloxacin. An affinity chromatographic study using a quinolone photoadduct-specific monoclonal antibody as ligand demonstrated preferential photocoupling of ofloxacin with a lysine-containing peptide. CD4+ T cells were purified from lymph nodes of BALB/c mice sensitized subcutaneously with ofloxacin-photomodified epidermal cells and from those sensitized epicutaneously via barrier-disrupted skin with a major histocompatibility complex class II (I-Ad)-binding, ofloxacin-photoconjugated peptide. These immune T cells proliferated in vitro in response to Langerhans cells loaded with class II-binding, lysine-containing peptides when photomodified with ofloxacin. Furthermore, epicutaneous application of the ofloxacin-photoconjugated peptide was able to prime mice for subsequent elicitation of photoallergy evoked with systemic ofloxacin and ultraviolet A light. This study suggests that lysine affords quinolone photocoupling of peptides and quinolone-photomodified peptides on class II molecules stimulate pathogenetic T cells in quinolone photoallergy.  (+info)

Delayed reactivation of haloperidol induced photosensitive dermatitis by methotrexate. (5/26)

A man whose psoriasis was well controlled on methotrexate treatment developed pellagra-like photosensitive dermatitis when he started taking haloperidol. Reactivation of his dermatitis was observed with methotrexate as a recall photosensitivity phenomenon. This false photosensitivity reaction of methotrexate is an important but rarely encountered adverse effect. A possible interaction between methotrexate and haloperidol is emphasised.  (+info)

Ultraviolet radiation causes less immunosuppression in patients with polymorphic light eruption than in controls. (6/26)

It is hypothesized that polymorphic light eruption is characterized by a partial failure of ultraviolet radiation-induced immunosuppression, resulting in a delayed-type hypersensitivity response to photo-induced antigens. We aimed to study the susceptibility of PLE patients to UVR-induced immunosuppression, by measuring the strength of sensitization to 2,4-dinitrochlorobenzene after UVR exposure, and to diphenylcyclopropenone without UVR exposure, in subjects with PLE and controls. Thirteen PLE patients and 11 controls were exposed to 1 minimum erythema dose (MED) of UVR delivered from Waldmann UV-6 bulbs to the upper inner arm. Twenty-four hours later at the same site they were exposed to a sensitizing dose of 2,4-dinitrochlorobenzene. One week later they were exposed to a sensitizing dose of diphenylcyclopropenone at a nonirradiated site. Three weeks later all subjects were challenged with four doses of 2,4-dinitrochlorobenzene and four doses of diphenylcyclopropenone. The resulting increase in skin thickness was measured with Harpenden callipers and summed over the four doses, to give a single value representing the reactivity of the subject to 2,4-dinitrochlorobenzene (Sigma DN) and diphenylcyclopropenone (Sigma DP). Among all subjects, there was a very strong correlation between Sigma DN and Sigma DP (Pearson correlation 0.56, p=0.004). The strength of the reaction to 2,4-dinitrochlorobenzene relative to the reaction to diphenylcyclopropenone was significantly greater among PLE patients than controls (p=0.04 independent samples t test of Sigma DP-Sigma DN). We conclude that induction of sensitization by 2,4-dinitrochlorobenzene is suppressed less by UVR in patients with PLE than in healthy controls.  (+info)

Ultraviolet-radiation-induced erythema and suppression of contact hypersensitivity responses in patients with polymorphic light eruption. (7/26)

Ultraviolet-radiation suppresses cell-mediated immunity in healthy humans. It has been postulated that, in the short term, this immunosuppression prevents autoimmune responses to ultraviolet-radiation damaged skin. Patients with polymorphic light eruption (PLE) demonstrate abnormal responses to ultraviolet-radiation suggestive of an immune response to an ultraviolet-radiation-induced antigen. We investigated whether PLE patients (n=22) were resistant to ultraviolet-radiation-induced immunosuppression compared to skin-type, aged-matched controls (n=23). Groups of patients and controls (six subjects per group) received a single dose of solar-simulated ultraviolet-radiation of either 0, 0.6, 1 or 2 minimal erythema doses (MED). Erythema was quantified using a reflectance meter and all volunteers were sensitised on the irradiated site with dinitrochlorobenzene. Contact hypersensitivity responses (CHS) to dinitrochlorobenzene were quantified after challenge using ultrasound. Ultraviolet-radiation-induced erythema was comparable in patients and controls. CHS was comparable in unirradiated patients and controls. UVR-induced a dose-dependent suppression of CHS in all volunteers but patients were more resistant to immunosuppression after 1MED. Exposure to 1MED suppressed CHS by 78% in controls but induced less suppression in patients (44%, p < 0.01). Our data suggest that PLE patients have a flaw in their immunoregulatory response to ultraviolet-radiation it is only apparent over a narrow dose range around 1 MED.  (+info)

The effect of solar-simulated radiation on the elicitation phase of contact hypersensitivity does not differ between controls and patients with polymorphic light eruption. (8/26)

It has been suggested that polymorphic light eruption (PLE) is characterized by a failure of ultraviolet radiation (UVR)-induced immunosuppression, resulting in a type-IV hypersensitivity response to photoinduced antigens. We measured the effect of solar-simulated radiation (SSR) on the elicitation phase of contact hypersensitivity to 2,4-dinitrochlorobenzene (DNCB), in ten PLE patients and 11 controls. Subjects were given a sensitizing dose of DNCB, and 3 wk later were exposed to 0.75 and 2 minimum erythema doses (MED) of SSR on the upper inner arm. Immediately and 24 h later these sites, and a non-irradiated control site, were challenged with DNCB. The resulting increase in skin thickness was measured with high-frequency ultrasound. Overall, 2 MED caused 17%-20% suppression of elicitation responses (compared with 93% suppression of sensitization reported previously), but the effect of SSR varied greatly between subjects, with some subjects showing potentiated responses, which may be of relevance to false-positive reactions in photopatch testing. In a repeated measures general linear model, SSR overall caused significant suppression of responses (p<0.001); there was less suppression in older subjects (p=0.009) but there was no significant difference between PLE patients and age-matched normal controls. These results contrast with our previous finding of a resistance to UVR-induced suppression of sensitization to DNCB in PLE. This difference may reflect the greater importance of Langerhans cells in the sensitization phase, and is consistent with the hypothesis that PLE arises from impaired suppression of Langerhans cell activation or migration.  (+info)

Photoallergic dermatitis is a type of contact dermatitis that occurs as a result of an allergic reaction to a substance after it has been exposed to ultraviolet (UV) light. This means that when the substance (allergen) comes into contact with the skin and is then exposed to UV light, usually from the sun, an immune response is triggered, leading to an inflammatory reaction in the skin.

The symptoms of photoallergic dermatitis include redness, swelling, itching, and blistering or crusting of the skin. These symptoms typically appear within 24-72 hours after exposure to the allergen and UV light. The rash can occur anywhere on the body but is most commonly found in areas that have been exposed to the sun, such as the face, neck, arms, and hands.

Common allergens that can cause photoallergic dermatitis include certain medications, fragrances, sunscreens, and topical skin products. Once a person has become sensitized to a particular allergen, even small amounts of it can trigger a reaction when exposed to UV light.

Prevention measures for photoallergic dermatitis include avoiding known allergens, wearing protective clothing, and using broad-spectrum sunscreens that protect against both UVA and UVB rays. If a reaction does occur, topical corticosteroids or oral antihistamines may be prescribed to help relieve symptoms.

Phototoxic dermatitis is a skin reaction that occurs when certain chemicals (known as photosensitizers) in a substance come into contact with the skin and then are exposed to sunlight or artificial UV light. This results in an exaggerated sunburn-like reaction, characterized by redness, swelling, itching, and sometimes blistering of the skin. The reaction usually occurs within a few hours to a couple of days after exposure to the offending agent and light. Common causes include certain medications, essential oils, fragrances, and plants like limes, celery, and parsley. Once the irritant is no longer in contact with the skin and sun exposure is avoided, the symptoms typically resolve within a week or two. Prevention includes avoiding the offending agent and protecting the skin from sunlight through the use of clothing, hats, and broad-spectrum sunscreens.

Atopic dermatitis is a chronic, inflammatory skin condition that is commonly known as eczema. It is characterized by dry, itchy, and scaly patches on the skin that can become red, swollen, and cracked over time. The condition often affects the skin on the face, hands, feet, and behind the knees, and it can be triggered or worsened by exposure to certain allergens, irritants, stress, or changes in temperature and humidity. Atopic dermatitis is more common in people with a family history of allergies, such as asthma or hay fever, and it often begins in infancy or early childhood. The exact cause of atopic dermatitis is not fully understood, but it is thought to involve a combination of genetic and environmental factors that affect the immune system and the skin's ability to maintain a healthy barrier function.

Dermatitis is a general term that describes inflammation of the skin. It is often characterized by redness, swelling, itching, and tenderness. There are many different types of dermatitis, including atopic dermatitis (eczema), contact dermatitis, seborrheic dermatitis, and nummular dermatitis.

Atopic dermatitis is a chronic skin condition that often affects people with a family history of allergies, such as asthma or hay fever. It typically causes dry, scaly patches on the skin that can be extremely itchy.

Contact dermatitis occurs when the skin comes into contact with an irritant or allergen, such as poison ivy or certain chemicals. This type of dermatitis can cause redness, swelling, and blistering.

Seborrheic dermatitis is a common condition that causes a red, itchy rash, often on the scalp, face, or other areas of the body where oil glands are located. It is thought to be related to an overproduction of oil by the skin's sebaceous glands.

Nummular dermatitis is a type of eczema that causes round, coin-shaped patches of dry, scaly skin. It is more common in older adults and often occurs during the winter months.

Treatment for dermatitis depends on the underlying cause and severity of the condition. In some cases, over-the-counter creams or lotions may be sufficient to relieve symptoms. Prescription medications, such as corticosteroids or immunosuppressants, may be necessary in more severe cases. Avoiding triggers and irritants can also help prevent flare-ups of dermatitis.

Allergic contact dermatitis is a type of inflammatory skin reaction that occurs when the skin comes into contact with a substance (allergen) that the immune system recognizes as foreign and triggers an allergic response. This condition is characterized by redness, itching, swelling, blistering, and cracking of the skin, which usually develops within 24-48 hours after exposure to the allergen. Common allergens include metals (such as nickel), rubber, medications, fragrances, and cosmetics. It is important to note that a person must first be sensitized to the allergen before developing an allergic response upon subsequent exposures.
