Prevention of experimentally induced irritant contact dermatitis by extracts of Isatis tinctoria compared to pure tryptanthrin and its impact on UVB-induced erythema.

Lipophilic extracts of Isatis tinctoria L. exhibit significant activity against several clinically relevant targets of inflammation. The alkaloid tryptanthrin was identified as one of the active principles in woad and characterised as a potent dual inhibitor of COX-2 and 5-LOX. Here, the anti-inflammatory efficacy of topical application of three different Isatis extracts and tryptanthrin was investigated in human volunteers. Two different models were used, namely the sodium lauryl sulphate (SLS)-induced irritant contact dermatitis (ICD) and UVB-induced erythema. Twenty healthy volunteers without any skin disease participated in the study. Cumulative irritant contact dermatitis was induced on test fields on the volunteers' backs by twice daily application of 0.5 % sodium lauryl sulphate over a period of four days. Half of the test fields were treated with the test substances during the eliciting phase, while the remaining test fields were treated over a period of 4 days after induction of dermatitis. In the second model, a UVB erythema on the volunteers' lower backs was induced using the double minimal erythema dose (MED). Twenty-four hours after irradiation the test fields were treated with the test substances over a period of 3 days. All reactions were assessed visually and by non-invasive bioengineering methods (evaporimetry and chromametry). Treatment with extracts during the ICD eliciting phase led to a significantly smaller increase of visual scores and transepidermal water loss compared to the untreated test field. For tryptanthrin this benefit was also observed, but the improvement was not statistically significant. When treatment was performed after completing the eliciting phase, accelerated resolution of the irritant reaction could not be observed. In the UVB erythema model anti-inflammatory effects of the test substances were not observed.

[Multilocular erythema migrans in borreliosis].

BACKGROUND: Borreliosis is the most common vector transmitted disease in childhood. Although the disease manifests with an erythema migrans in 80 % of the patients, multilocular skin manifestations are only observed in 2-18 % of these. Differential diagnoses of erythema migrans include erysipelas, persistent insect bite reaction, and fixed drug eruption, in particular when the clinical history does not reveal a tick bite. PATIENT: We report on a 5-year-old boy showing nine erythemas with central pallor on his face, trunk, arms and legs. He recalled a tick bite 3 weeks before. RESULTS: Serological studies revealed an acute infection with Borrelia burgdorferi. After antibiotic treatment with orally administered amoxicillin skin manifestations resolved within three days. During a follow-up period of six months the patient revealed no signs of persistent borreliosis. CONCLUSION: Multilocular erythema migrans is a possible manifestation of borreliosis and is classified as disseminated early infection which is frequently associated with systemic reactions, including malaise, arthritis, carditis, headache and even meningeal signs. Treatment is based on antibiotics, which should preferably be given intravenously in case of systemic signs.

Painless erythema of the hands associated with non-Hodgkin's lymphoma in a lung transplant recipient.

Acral erythema limited to the fingers or the hands has been described in systemic disease. We report the case of a 17-year-old patient who had undergone lung transplantation for cystic fibrosis. Six weeks after transplantation, rapidly growing large-cell immunoblastic non-Hodgkin's lymphoma of the lungs and mediastinum was diagnosed. Sharply demarcated, painless, glovelike erythema was found on both hands. Therapy was reduction of immunosuppression and 12 cycles of extracorporeal photophoresis. After 4 months, lymphoma was in clinical and radiologic remission. Bilateral erythema of the hands also had disappeared. Acral erythema has been reported in association with chemotherapy, collagen vascular disease, infections as with HIV, hepatitis C virus, parvovirus B19, or cytomegalovirus. None of the described associations were detected in this case.

An experimental ointment formulation of pimecrolimus is effective in psoriasis without occlusion.

Pimecrolimus (Elidel, SDZ ASM 981), a new macrolactam ascomycin derivative, was highly effective in treating plaque-type psoriasis when applied under Finn-chamber occlusion. A two-centre, randomized, double-blind, vehicle- and positive-controlled within-patient study was therefore conducted in 23 adult psoriasis patients. Pimecrolimus 1% was applied, twice daily, in an experimental ointment formulation, along with the corresponding vehicle, 0.005% calcipotriol ointment and 0.05% clobetasol-17-propionate ointment to test sites without occlusion for 21 days. Erythema, induration and scaling (score: 0 [absent] to 4 [severe]) were evaluated. The total sign score was defined as the sum of the erythema, induration and scaling scores (range 0-12). Pimecrolimus 1% ointment was significantly (p = 0.03) more effective than the corresponding vehicle, with an improvement in total sign score of 51.4% compared with 36.7% for the corresponding vehicle. Improvements with calcipotriol and clobetasol-17-propionate were 71.5% and 88.3%, respectively. No local or systemic drug-related side effects were observed in the study. We conclude that pimecrolimus 1% in the experimental ointment formulation was significantly more effective than its corresponding vehicle, but less effective than calcipotriol and clobetasol ointment. This is the first study reporting a significant therapeutic effect of pimecrolimus in an ointment formulation applied without occlusion to psoriatic plaques.

Acral erythema caused by high-dose methotrexate therapy in patients with osteogenic sarcoma.

High doses of methotrexate (MTX) have been incorporated in the treatment of osteogenic sarcoma since the 1970s. Unfortunately, high-dose MTX (HD-MTX) can cause untoward side effects that may complicate the proper management of these patients. Two cases of MTX-induced acral erythema are described and the possible implications of this complication are reviewed, with a discussion of the pathophysiology of this adverse effect. Two young female patients suffering from osteogenic sarcoma received HD-MTX (12 g/m2) according to the chemotherapeutic protocol. A 17-year-old patient with osteogenic sarcoma of the head developed painful acral erythema of her palms and soles after the fifth dose of MTX, and a 22-year-old patient with osteosarcoma of the femur developed severe acral erythema after the sixth dose. The severity of the reaction was significant enough to cancel further treatment with HD-MTX in both patients. All symptoms resolved without sequellae several weeks later in both cases. Acral erythema may pose a significant albeit transient phenomenon adversely influencing chemotherapy in patients suffering from osteosarcoma and treated with HD-MTX. The pathophysiology of this side effect is not completely understood and further investigation of the pharmacokinetics of HD-MTX in this patient population is needed.

Erythema nodosum and antitubercular therapy.

OBJECTIVE: To establish the efficacy of antitubercular therapy in patients with erythema nodosum with a highly positive Mantoux test. METHODS: A retrospective analysis of all patients diagnosed with idiopathic erythema nodosum with a highly positive Mantoux reaction between 1988 and 2001 was undertaken. In the absence of any other clinical or investigative evidence of active tuberculosis they were treated with antitubercular therapy. RESULTS: Out of a total of 52 patients diagnosed with idiopathic erythema nodosum with a strongly positive Mantoux test (average of 19 mm), data could be analyzed in only 47 patients. After treatment with antitubercular drugs, new lesions stopped appearing in 45 patients within 6-8 weeks and subsided in two. The therapy was well tolerated except for jaundice in one patient and transient urticarial lesions in another. CONCLUSIONS: Antitubercular therapy definitely has a role in the management of patients with erythema nodosum, even in the absence of a detectable focus of tubercular infection, especially in regions where tuberculosis is endemic.

Accelerated reduction of post-skin-resurfacing erythema and discomfort with a combination of non-thermal blue and near infrared light.

The prolonged crusting and erythematic phases following chemical and laser skin resurfacing create discomfort and aggravate patients. Depending on the aggressiveness of the procedure, post-procedure erythema may last from three weeks to several months. iClearXL (CureLight Ltd) is a non-contact, non-thermal blue (405-420 nm)/near infrared (850-900 nm) dual-band light source emitting up to 60 J/cm2 on a 30 cm by 30 cm treatment area. The blue component of the light source has been proven to have a significant anti-inflammatory effect, whereas the near infrared component enhances vascular circulation as well as lymphatic drainage in the thin, necrotized papillary layer. Facial skin laser resurfacing was performed on twelve patients. Starting one day after resurfacing, six patients received a daily 20-minute treatment of blue (405-420 nm)/near infrared (850-900 nm) light for six consecutive days, and six control patients were treated with the usual topical care protocol. Twelve days after the procedure, the treated group had a weighted average erythema score of 0.33 as compared to 1.33 in the control group. Two months after the procedure, the treated group had a weighted average erythema score of 0.16 as compared to 0.83 in the control group. Twelve days after the procedure, the treated group had a weighted average discomfort score of 0.33 as compared to 0.83 in the control group. The tested combination of non-thermal blue (405-420 nm)/near infrared (850-900 nm) dual-band light was found to significantly shorten the duration of post-laser-resurfacing erythema and discomfort with no side effects.

Erythema nodosum in pregnant patients with coccidioidomycosis.

Pregnant patients with coccidioidomycosis develop dissemination and serious disease more frequently than do the general population. To assist in prognosis and management, we analyzed the significance of erythema nodosum in pregnant patients with coccidioidomycosis. Sixty-one pregnant patients (mean age +/- SD, 26.4 +/- 6.3 years) were evaluated. Seventy percent of the patients were Hispanic; 15%, African American; 13%, Caucasian; and 2%, unknown race. Of the 30 patients (49%) who developed erythema nodosum, 0 had disseminated disease (P = .001), 1 (3%) with pulmonary involvement required therapy for > 1 year, and 29 (97%) recovered (P = .0008). Of the 31 patients (51%) without erythema nodosum, 11 (35%) had disseminated disease, 12 (39%) required therapy for > 1 year, 17 (55%) recovered, 1 (3%) died, and 1 (3%) had an outcome that was unknown. Erythema nodosum appears to be a salient marker of a positive outcome for pregnant patients, more so than for the general population.

The role of parvovirus B19 in aplastic crisis and erythema infectiosum (fifth disease).

In 1984, simultaneous outbreaks of aplastic crisis and erythema infectiosum occurred in northeastern Ohio. Sera were analyzed from 26 patients with aplastic crisis: 24 had IgM specific for parvovirus B19, five had B19-like particles by electron microscopy, and 13 had DNA from B19; no sera from 33 controls had evidence of recent infection with B19 (P less than .0001). DNA from B19 was also detected in specimens of throat gargle and urine from two patients with aplastic crisis. Sera from 36 of 51 children with erythema infectiosum had B19-specific IgM, compared with serum from one of 42 susceptible controls (P less than .0001). DNA from B19 was detected in sera from only two of 51 patients who had erythema infectiosum. The secondary attack rates among susceptible contacts decreased with age (overall total, 49.6%). Differential rates of asymptomatic infection were observed among black (68.8%) and white (20.0%) household members (P = .003). These were the first identified simultaneous outbreaks of aplastic crisis and erythema infectiosum. Their occurrence provided an opportunity to study the epidemiology and spectrum of B19 infection with geographically and temporally matched comparison groups; our results support the hypothesis that infection with parvovirus causes these two clinical entities.

Erythema nodosum in patients with tinea pedis and onychomycosis.

To document association between erythema nodosum and concomitant fungus infection, we studied seven white women seen during a six-year period in our office practice. Five patients are presented. Unilateral erythema nodosum occurred in three patients on the same side as unilateral tinea. Tests with potassium hydroxide (KOH), cultures of nodules on Sabouraud agar and dermatophyte test medium (DTM), skin biopsy, and clinical examination ruled out nodular granulomatous perifolliculitis of Wilson. Lesions simulating erythema nodosum were produced when Trichophyton antigen was injected subcutaneously in the lower legs. All nodose and fungal lesions cleared after griseofulvin therapy. Fungus infection of feet or nails should be considered a possible cause of erythema nodosum when no other cause is apparent.

Erythema nodosum associated with diffuse, large B-cell non-Hodgkin lymphoma detected by FDG PET.

A patient is described with non-Hodgkin lymphoma and erythematous skin nodules suspected to be erythema nodosum. The patient underwent serial fluorodeoxyglucose (FDG) positron emission tomography (PET), which demonstrated normalization of FDG uptake by the lymphoma after 2 cycles of chemotherapy, but there was new abnormal uptake involving the subcutaneous tissues of the lower extremities. A typical skin lesion was sampled and showed the appearance of erythema nodosum with no evidence of lymphoma. The FDG uptake gradually diminished on serial PET imaging after treatment with nonsteroidal antiinflammatory drugs. In view of the recognized association of erythema nodosum with malignancy and the differential rate of response to chemotherapy, the lesions of erythema nodosum may be a source of a false-positive PET interpretation, and histologic assessment should be considered.

Erythema marginatum and hereditary angioedema.

OBJECTIVE: To search for anaphylatoxin activity in plasma during episodes of erythema marginatum, and to evaluate the histology of erythema marginatum by electron microscopy and immunohistologic techniques. METHODS: Plasma samples were studied for C5a activity by granulocyte aggregation, and C3 conversion by immunoelectrophoresis. A skin biopsy of erythema marginatum was done, and the tissue stained with a rabbit antibody to bradykinin. RESULTS: No plasma anaphylatoxin was found. Dense deposits of bradykinin were discovered in stromal tissue and lining endothelial cells. CONCLUSIONS: Bradykinin may be important in the causality of the erythema marginatum associated with hereditary angioedema.

UVA-induced erythema, pigmentation, and skin surface temperature changes are irradiance dependent.

Human cutaneous erythemogenic and melanogenic responses to long-wave (UVA) ultraviolet radiation were investigated using irradiances ranging from 5-50 mW/cm2. Skin surface temperature changes resulting from the different irradiances were also compared. In general, threshold doses for erythema and pigmentation were higher when UVA was administered at the lowest irradiance (5 mW/cm2) than at the highest (50 mW/cm2). Erythema was maximal immediately after exposure to UVA. The most intense responses (erythema with edema, or intense pigmentation) were induced more frequently by the highest irradiance. Components of both the erythema and the pigment response to UVA are therefore irradiance-dependent. The greatest increase in skin surface temperature was observed after exposure to the highest irradiance.

An action spectrum for the elicitation of erythema in skin persistently sensitized by photobound 8-methoxypsoralen.

Human skin can be rendered persistently photosensitive by topical application of aqueous 8-methoxypsoralen (8-MOP) and exposure to a suberythemogenic dose of more than 380 nm radiation. We report an action spectrum for the elicitation of phototoxic erythema induced by a second exposure of skin pretreated in this way. After correction for unsensitized skin erythema this action spectrum resembles the absorption spectrum of the 4',5'-monoadduct of 8-MOP to DNA. This suggests that the monoadduct is the chromophore for erythema elicited by the second irradiation, and supports the DNA crosslink as the crucial photoproduct causing phototoxic erythema due to 8-MOP in human skin.

Relapsing annular erythema and myeloma successfully treated with cyclophosphamide.

We report the history of a patient, who had recurrent patches of erythema on the trunk and extremities for some years. The diagnosis of erythema elevatum diutinum or annulare centrifugum was discussed. The patient developed a monoclonal IgA lambda fraction and clinical signs of myeloma. Treatment with cyclophosphamide stopped the development of erythema and also caused the M-component to disappear. This improvement has persisted even without cytostatic treatment. Another patient with prostatic carcinoma and relapsing annular erythema was cured of his skin lesions, when his carcinoma was treated with estrogens. The literature is reviewed.

Lymphocyte response to staphylococcal enterotoxin B in patients with annular erythema associated with Sjögren syndrome.

Lymphocyte response to staphylococcal enterotoxin B (SEB) was analysed in 11 cases with Sjögren syndrome (SjS) who developed annular erythema during the course. Increased lymphocyte response against SEB was observed on day 5 in those patients who developed annular erythema at the time of examination. A similar reaction pattern was observed when Con A and PWM, but not protein A, were used as the mitogen. No significant lymphocyte response was observed in the patients in the inactive stage without annular erythema or in normal controls. Furthermore, peripheral blood lymphocytes express LFA-1 after SEB stimulation. These results suggest that lymphocytes from SjS patients react to various types of antigenic or mitogenic stimulation and that they express cell adhesion molecules, especially in patients with active annular erythema.

Spongiotic annular erythema in SS-A/SS-B antibody negative Sjögren's syndrome.

We reported four cases of Sjögren's syndrome (SjS) who manifested a new type of annular erythema that differs from the previously described annular erythema seen in anti-SS-A/SS-B antibody positive SjS in both clinical and histological findings. Characteristic histological features are the presence of spongiotic changes around the acrosyringium and perivascular lymphocytic infiltration without liquefaction degeneration or epidermal change, suggesting lupus erythematosus. No complement or immunoglobulin depositions are demonstrated along the basement membrane zone or around blood vessels. Clinically, this type of erythema usually appears on the trunk or extremities with itchy sensations, especially in summer, which contrasts with the preferential occurrence of the previously reported SjS related annular erythema on the facial skin in winter. Immunologically, all four cases lacked anti-SS-A and anti-SS-B antibodies, but possessed positive anti-microsome antibodies or thyroid tests. In three cases, metal allergy was demonstrated by patch test, which might suggest that the sweat duct is the primary target of excreted metals in this condition and that underlying SjS might play some role in the higher prevalence of metal allergy or in induction of sweat duct injury, similar to the interstitial nephritis which is now thought to be an exocrine manifestation of SjS.

Recurrent annular erythema in a case of seronegative Sjögren's syndrome.

We describe a case of Sjögren's syndrome who repeatedly developed annular erythema on her extremities. Her anti-nuclear antibody, anti-SSA/Ro antibody, and anti-SSB/La antibody were all negative. Characteristics of the annular erythema included a tendency to appear on the extremities especially in summer, spontaneous regression after 1-2 weeks, and residual slight pigmentation. The histological findings revealed dermal perivascular lymphocytic infiltration admixed with some neutrophils. Slight exsudative changes were found in the upper dermis. There were no epidermal changes. This case suggests the existence of annular erythema which may not be related to the anti-SSA/Ro or anti-SSB/La antibody. Unknown factors other than those antibodies may be involved in the pathogenesis of the annular erythema.
