RESUMO

BACKGROUND: Dupilumab (an anti-interleukin-4-receptor-α monoclonal antibody) blocks signalling of interleukin 4 and interleukin 13, type 2/Th2 cytokines implicated in numerous allergic diseases ranging from asthma to atopic dermatitis. Previous 16-week monotherapy studies showed that dupilumab substantially improved signs and symptoms of moderate-to-severe atopic dermatitis with acceptable safety, validating the crucial role of interleukin 4 and interleukin 13 in atopic dermatitis pathogenesis. We aimed to evaluate the long-term efficacy and safety of dupilumab with medium-potency topical corticosteroids versus placebo with topical corticosteroids in adults with moderate-to-severe atopic dermatitis. METHODS: In this 1-year, randomised, double-blinded, placebo-controlled, phase 3 study (LIBERTY AD CHRONOS), adults with moderate-to-severe atopic dermatitis and inadequate response to topical corticosteroids were enrolled at 161 hospitals, clinics, and academic institutions in 14 countries in Europe, Asia-Pacific, and North America. Patients were randomly assigned (3:1:3) to subcutaneous dupilumab 300 mg once weekly (qw), dupilumab 300 mg every 2 weeks (q2w), or placebo via a central interactive voice/web response system, stratified by severity and global region. All three groups were given concomitant topical corticosteroids with or without topical calcineurin inhibitors where inadvisable for topical corticosteroids. Topical corticosteroids could be tapered, stopped, or restarted on the basis of disease activity. Coprimary endpoints were patients (%) achieving Investigator's Global Assessment (IGA) 0/1 and 2-point or higher improvement from baseline, and Eczema Area and Severity Index 75% improvement from baseline (EASI-75) at week 16. Week 16 efficacy and week 52 safety analyses included all randomised patients; week 52 efficacy included patients who completed treatment by US regulatory submission cutoff. This study is registered with ClinicalTrials.gov, NCT02260986. FINDINGS: Between Oct 3, 2014, and July 31, 2015, 740 patients were enrolled: 319 were randomly assigned to dupilumab qw plus topical corticosteroids, 106 to dupilumab q2w plus topical corticosteroids, and 315 to placebo plus topical corticosteroids. 623 (270, 89, and 264, respectively) were evaluable for week 52 efficacy. At week 16, more patients who received dupilumab plus topical corticosteroids achieved the coprimary endpoints of IGA 0/1 (39% [125 patients] who received dupilumab plus topical corticosteroids qw and 39% [41 patients] who received dupilumab q2w plus topical corticosteroids vs 12% [39 patients] who received placebo plus topical corticosteroids; p<0·0001) and EASI-75 (64% [204] and 69% [73] vs 23% [73]; p<0·0001). Week 52 results were similar. Adverse events were reported in 261 (83%) patients who received dupilumab qw plus topical corticosteroids, 97 (88%) patients who received dupilumab q2w, and 266 (84%) patients who received placebo, and serious adverse events in nine (3%), four (4%), and 16 (5%) patients, respectively. No significant dupilumab-induced laboratory abnormalities were noted. Injection-site reactions and conjunctivitis were more common in patients treated with dupilumab plus topical corticosteroids-treated patients than in patients treated with placebo plus topical corticosteroids. INTERPRETATION: Dupilumab added to standard topical corticosteroid treatment for 1 year improved atopic dermatitis signs and symptoms, with acceptable safety.

RESUMO

The aim of this study is the evaluation of the relation between the sensitisation to outdoor and indoor fungi and allergy to peanuts and walnuts in atopic dermatitis patients aged 14 years and older. The complete dermatological and allergological examinations were performed in all included patients; the occurrence of food allergy to peanuts and walnuts was recorded (specific IgE, skin prick test, history of allergic reaction) and the sensitisation to mixture of outdoor fungi and indoor fungi was also examined (skin prick test, specific IgE). The statistical evaluation of the relation between the sensitisation to outdoor and indoor fungi and the occurrence of food allergy to peanuts and walnuts was performed; 329 patients were included in the study, 110 men and 219 women, the average age 26.8 years. The sensitisation to outdoor fungi was recorded in 91 patients (28%), the sensitisation to indoor fungi was recorded in 61 patients (18.5%), the occurrence of food allergy to peanuts was confirmed in 90 (27%) patients and to walnuts in 121 (36.7%) patients. We confirmed, that patients suffering from sensitisation to outdoor fungi suffer significantly more from food allergy to peanuts and walnuts. The significant relation between the sensitisation to indoor fungi and food allergy to peanuts and walnuts was not confirmed.

RESUMO

BACKGROUND: A few reports demonstrate the occurrence of egg allergy in adolescent and adult patients suffering from atopic dermatitis and the association of this allergy to other food and aeroallergens. AIMS AND OBJECTIVES: The aim of this study is to evaluate the occurrence of egg allergy in patients suffering from atopic dermatitis at the age 14 years and older and to evaluate the relationship between egg allergy or egg sensitisation and the sensitisation to dust, mites, feather, and animal dander. MATERIALS AND METHODS: Complete dermatological and allergological examination was performed. These parameters were examined: food allergy and food sensitisation to egg white and yolk, to mites, animal dander (mixture), feather and dust. The statistical evaluation of the relations among egg allergy, egg sensitisation and sensitisation to mites, animal dander (mixture), feather and dust was performed. Two hundred and eighty eight patients were included in the study (90 men, 198 women, with the average age 25.2). RESULTS AND CONCLUSION: Egg allergy was recorded in 5% and egg sensitisation in 20% of patients; sensitisation to dust is recorded more often in patients with positive results in sIgE for egg white and/or yolk.

RESUMO

UNLABELLED: Aim of our study was to evaluate the importance of atopy patch testing with aeroallergens as a diagnostic method in patients suffering from atopic dermatitis. METHOD: The complet dermatological and allergological examinations were performed in 29 patients; 10 men, 19 women with the average age of 27.8 years, min. 17, max. 57 years; with the median SCORAD 24.2 points, s.d. 13.3 points. Wormwood, grass, dog dander, cat dander, dermatophagoides pharinae, dermatophagoides pteronyssinus and birch pollen were examined in diagnostic procedures. Skin prick tests, specific IgE were examined; the atopy patch tests were performed with aeroallergens for skin prick tests in concentration 1 x skin prick tests. RESULTS: Specific IgE and skin prick tests to one or more tested aeroallergens were positive altogether in 27 patients; atopy patch tests were positive only in one of these patients. CONCLUSION: For atopy patch testing with aeroallergens the concentration of 1 x skin prick tests is low to confirme the eczematic reaction in patients suffering from allergy to inhallant allergens.

RESUMO

UNLABELLED: Few studies concerning the occurrence of cow's milk allergy with the use of double-blind, placebo controlled food challenge test in adolescents and adult patients suffering from atopic dermatitis exist. AIM: To evaluate the occurrence of cow's milk allergy in adolescents and adults suffering from atopic dermatitis. METHOD: Altogether 179 persons suffering from atopic dermatitis were included in the study: 51 men and 128 women entered the study with the average age of 26.2 (s.d. 9.5 years). Complete dermatological and allergological examinations were performed. RESULTS: The positive results in specific IgE and in skin prick tests were recorded in 12% of patients. According to the open exposure tests and double-blind, placebo controlled food challenge tests these patients are only sensitized to cow's milk without clinical symptoms of allergy. Double-blind, placebo controlled food challenge test confirmed food allergy to cow milk only in one patient (worsening of atopic dermatitis), the oral allergy syndrome was observed in another one patient, occurrence of this allergy was altogether 1.1%. CONCLUSION: Cow's milk allergy rarely plays a role in the worsening of atopic dermatitis in adolescent and adult patients.

RESUMO

Sweet syndrome also termed acute febrile neutrophilic dermatosis is characterized by the abrupt onset of fever, leukocytosis and demarcated papules and nodules, which show dense neutrophilic infiltrates in histopathology. This syndrome is often associated with malignant and immunological conditions. Treatment with systemic glucocorticoids is successful. In the following we describe a case of a 66 year-old woman patient, who had skin problems after being reoperated for umbilical hernia.

RESUMO

UNLABELLED: Few studies concerning the importance of wheat allergy affecting the course ofatopic eczema in adolescents and adult patients exist. AIM: The evaluation if wheat allergy can deteriorate the course of atopic eczema. Follow-up of patients with confirmed food allergy to wheat. METHOD: Altogether 179 persons suffering from atopic eczema were included in the study: 51 men and 128 women entered the study with an average age of 26.2 (s.d. 9.5 years) Dermatological and allergological examinations were performed, including skin prick tests, atopy patch tests, and specific serum IgE for wheat, open exposure test and double-blind, placebo-controlled food challenge test with wheat flour. RESULTS: Wheat allergy affecting the coures of atopic eczema was confirmed in eight patients (4.5%) out of 179 patients enrolled in this study by double-blind, placebo controlled food challenge test. The course of atopic eczema showed a positive trend in patients with confirmed food allergy at 3, 6, 9, 12 month follow-up (statistical evaluation with paired t-test) after the elimination of wheat flour. CONCLUSION: Wheat allergy may play an important role in the worsening of atopic eczema (acting as a triggering exacerbating factor) only in a minority of adolescents and adult patients (4.5% in our study). The diagnostic methods (skin prick test, specific IgE, atopy patch test, history) cannot be used as separated tests for the determination of food allergy to wheat in patients with atopic eczema.Open exposure tests and double-blind, placebo-controlled food challenge should be used for the confirmation of wheat allergy affecting the course of atopic eczema.

RESUMO

BACKGROUND: Goeckerman's therapy (GT) of psoriasis is based on daily application of pharmacy grade coal tar on affected skin with subsequent exposure to UV light. Disturbances in angiogenic activity are characteristic for the immunopathogenesis of psoriasis. The aim of study was to evaluate the influence of GT of psoriasis on proinflammatory and angiogenic activities expressed as changes in levels of endoglin (CD105). METHODS: Serum levels of a soluble form of endoglin were measured in peripheral blood samples of 38 patients with psoriasis before and after therapy. Sixty three otherwise healthy blood donors serve as a control group. The efficacy of GT was expressed as changes in Psoriasis Area and Severity Index (PASI). RESULTS: PASI score was significantly diminished by GT (p < 0.001). Serum levels of soluble CD105 were significantly diminished after GT. The serum level of soluble CD105 dropped from 7.85 +/- 2.26 ng/ml before therapy to 7.01 +/- 1.71 ng/ml after therapy (p = 0.0002). Compared to serum levels of soluble CD105 in healthy blood donors, serum levels of soluble CD105 in patients before GT were significantly higher (p < 0.001) and remained elevated after therapy (p < 0.001). Angiogenic activity expressed as serum endoglin is diminished in patients with psoriasis treated by GT.

RESUMO

INTRODUCTION: Atopic dermatitis (AD), a predominantly type 2 inflammatory skin disease, affects approximately 2-5% of adults, with a high burden of disease. In moderate-to-severe AD, lesions can be extensive and pruritus intense with patients experiencing skin pain, sleep and mental health disturbances, and diminished quality of life (QoL). METHODS: The objective of this study was to evaluate the efficacy of dupilumab for the treatment of AD from the patients' perspective using patient-reported outcome data from four clinical trials (CHRONOS, SOLO 1&2, and CAFÉ) in patients (N = 1553) receiving either the approved 300 mg q2w dupilumab with/without topical corticosteroids (TCS) dose or control (placebo or placebo + TCS). Patient Global Assessment of Disease Status (PGADS) was used to measure patients' well-being and Patient Global Assessment of Treatment Effect (PGATE) was used to measure treatment efficacy. Patients were asked "Considering all the ways in which your eczema affects you, indicate how well you are doing" to assess their perception of well-being and "How would you rate the way your eczema responded to the study medication?" to assess their perception of treatment effect. Possible responses for both metrics included poor, fair, good, very good, and excellent. RESULTS: In all four studies, a significantly higher proportion of dupilumab-treated patients reported "Good"/"Very Good"/"Excellent" disease status from week 2 through study end versus control (CHRONOS, 52 weeks: 69.8% vs. 25.1%; SOLO 1&2, 16 weeks: 59.5% vs. 24.6%; CAFÉ, 16 weeks: 84.1% vs. 45.4%; all P < 0.0001), and significantly more dupilumab-treated patients reported "Good"/"Very Good"/"Excellent" treatment efficacy versus control (CHRONOS: 72.6% vs. 24.8%; SOLO 1&2: 65.0% vs. 21.1%; CAFÉ, 16 weeks: 85.0% vs. 36.1%; all P < 0.0001). CONCLUSION: Adult patients with AD perceived that dupilumab with/without concomitant TCS was highly efficacious and improved overall disease status and well-being as early as week 2 and throughout treatment periods up to 1 year.

RESUMO

UNLABELLED: Few studies concerning the importance of food allergy in adolescents and adult patients with atopic eczema exist. The atopy patch tests with food have mostly been studied in infants and children since food allergy plays a role especially in this age group. AIM: The evaluation of the contribution of atopy patch tests in the diagnostic work-up of food allergy (to wheat, cow milk, peanuts, soya and eggs) in the patients with atopic eczema older than 14 years of age. METHOD: 120 patients were examined in the study in the diagnostic work-up of food allergy--86 women and 34 men, the mean age 26.5 (s.d. 9.8) and the median SCORAD at the beginning of the study 32.9 (s.d. 14.0). Complete dermatological and allergological examinations in the diagnostic work-up of food allergy were performed (assessment of personal history, assessment of serum specific IgE, skin prick tests, atopy patch tests, diagnostic hypoallergenic diet, food challenge tests with egg, soy, wheat, cow milk and double-blind, placebo-controlled food challenge test with cow milk and wheat. The results of atopy patch tests were compared with the results of other diagnostic methods in the diagnosis of food allergy. RESULTS: The food allergy to cow milk and wheat was confirmed in double-blind, placebo controlled food challenge test in few patients in our study (4%). The suspicion of food allergy to egg is in 8 %, to peanuts in 13 % and to soya in 4 % of patients in our study. The assessment of atopy patch tests response seems to be of great importance. The reaction in atopy patch tests with more papules has the greatest diagnostic accuracy for predicting the result of challenge tests. At the beginning and at the end of diagnostic hypoallergenic diet the severity of atopic eczema/dermatitis syndrome was recorded in all patients enrolled in the study by evaluating SCORAD. The decrease of SCORAD was statistically important. CONCLUSION: Atopy patch tests alone cannot be used as a single test for the determination of food allergy in patients with atopic eczema/dermatitis syndrome but such a test, together with other diagnostic methods, can help to trace the food allergy.

RESUMO

The Goeckerman regimen (GR) represents a local treatment of psoriasis and includes topical dermal application of crude coal tar (containing polycyclic aromatic hydrocarbons) and exposure to UV-irradiation. The aim of the study was to evaluate contribution of GR to genotoxic risk and cellular stress in pediatric patients who represent a sensitive population subgroup. Genotoxic risk (42 patients) was evaluated by using chromosomal aberrations (CA) in peripheral lymphocytes. Cellular stress (26 patients) was assessed by using heat shock proteins (Hsp70). All indicators were determined in blood samples collected before GR and immediately after GR. Decreasing of psoriasis area and severity index (PASI) score indicated higher likelihood of GR (p < 0.001). Significantly increased CA (p < 0.001) and Hsp70 (p < 0.05) indicated higher genotoxic risk and cellular stress in sensitive pediatric patients, immediately after GR.

RESUMO

Goeckerman's therapy (GT) of psoriasis is based on daily application of pharmacy grade coal tar on affected skin with subsequent exposure to UV light. The aim of this study was to evaluate the influence of Goeckerman's therapy of psoriasis on the levels of proangiogenic chemokines ENA-78 (CXCL5, Epithelial Cell Derived Neutrophil Attractant-78), GRO alpha (CXCL1, Growth-Related Oncogene), IL-8 (CXCL8, Interleukin-8), MCP-1 (CCL2, Monocyte Chemotactic (Chemoattractant) Protein 1) and RANTES (CCL5, Regulated on Activation of Normal T Cell Expressed and Secreted) in peripheral blood of 22 children's patients with psoriasis. 22 otherwise healthy children serve as a control group. The serum levels of chemokines were determined by commercial membrane protein array technique (RayBiotech, USA). Efficacy of Goeckerman's therapy was delineated by PASI score. Disease activity was significantly diminished by Goeckerman's therapy (p < 0.001). Serum levels of GRO alpha and MCP-1 in patients before GT were significantly higher than those measured in healthy blood donors (GRO alpha: p = 0.0128 and MCP-1: p = 0.0003). Serum levels of GRO alpha, MCP-1 and RANTES were significantly diminished by GT (GRO alpha: p = 0.002, MCP-1: p = 0.048 and RANTES: p = 0.0131). Compared to the healthy controls, serum level of MCP-1 remained significantly increased in psoriasis patients after GT (p < 0.0001). In conclusion, we found that the GT of psoriasis influenced the serum levels of proinflammatory and proangiogenic chemokines, especially GRO alpha, MCP-1 and RANTES. It could be the cause for decreased proangiogenic activity which is described after GT of psoriasis.

RESUMO

BACKGROUND: Although epidemiologic data are scarce, there is no doubt that the increase in pollen allergies is going to be followed by an increase in the so-called pollen-related food allergies. The aim of this study was the evaluation of the food hypersensitivity reactions in atopic dermatitis patients and the relation to the sensitization to grass and trees. METHODS: The complete dermatological and allergological examinations were performed in all included patients; the occurrence of food hypersensitivity reactions was recorded and the sensitization to inhalant allergens (grass and trees) was examined (skin prick test, and specific IgE). The statistical evaluation of the relation between the sensitization to these inhalant allergens and the occurrence of food hypersensitivity reactions was performed. RESULTS: A total of 321 patients were included, with an average age of 26.7 years (±9.2 years) and with an average SCORAD of 33.2 (±13.3) points. The significant relation was recorded between the patients suffering from sensitization to grass and the reactions to peanuts, celery and walnuts; another significant relation was demonstrated between the patients suffering from sensitization to trees and reactions to apple, peanuts, and walnuts. In patients suffering from sensitization to grass and trees, the occurrence of food hypersensitivity reactions to tomatoes, kiwi, spices, oranges, capsicum, tangerines, and carrot was higher also, but the relation was not significant. CONCLUSION: The significant relation was found between the reactions to peanuts and walnuts and sensitization to grass and trees, another significant relation was found between the sensitization to grass and celery and between the sensitization to trees and apple.

RESUMO

BACKGROUND: Eosinophils play an important pathogenic role in atopic dermatitis (AD), but its exact function remains to be determined. AIMS AND OBJECTIVES: The aim of this study was to correlate the eosinophil count with the manifestations such as asthma bronchiale, rhinitis, level of total IgE, sensitization to mites, animal dander, bird feather, dust, mixture of grass, mixture of trees, mixture of fungi, duration of lesions (persistent or occasional during last year), family history about atopy, and onset of AD (under or above 5 year of age). MATERIALS AND METHODS: Two hundred and seventy-two patients suffering from AD at the age of 14 year or older were examined - 100 men and 172 women with the average age of 26.7±9.5 years and with the average SCORAD index of 32.9±14.1. Complete dermatological and allergological examinations were performed in all patients with the evaluation of monitored manifestations. Mann-Whitney test for difference in medians was used for statistical evaluation. RESULTS: The count of eosinophils in peripheral blood was significantly higher in patients with total IgE ≥200 IU/ml, with sensitization to dust, with persistent eczematous lesions and in patients with the onset of AD under 5 year of age. The count of eosinophils above 5% was recorded as well in patients suffering from asthma bronchiale, rhinitis, sensitization to mites, and in patients with positive family history about atopy, but the difference was not significant. On the other hand, the count of eosinophils was under 5% in patients with sensitization to animal dander, bird feather, mixture of grass and trees. CONCLUSION: Our results demonstrated the difference in the count of eosinophils in peripheral blood according to different manifestations in patients suffering from AD.

RESUMO

Six out of 10 patients with chronic wounds suffer from persistent wound pain. A multinational and multicenter randomized double-blind clinical investigation of 122 patients compared two moist wound healing dressings: a nonadhesive foam dressing with ibuprofen (62 patients randomized to Biatain Ibu Nonadhesive Coloplast A/S) and a nonadhesive foam without ibuprofen (60 patients to Biatain Non-Adhesive-comparator). Patients were recruited from September 2005 to April 2006. The ibuprofen foam was considered successful if the pain relief on a five-point Verbal Rating Scale was higher than the comparator without compromising safety including appropriate healing rate. Additional endpoints were change in persistent wound pain between dressing changes and pain at dressing change on days 1-5 (double blind) and days 43-47 (single blind). The primary response variable, persistent pain relief, was significantly higher in the ibuprofen-foam group, as compared with the comparator on day 1-5, with a quick onset of action (p<0.05). Wound pain intensity was significantly reduced with the ibuprofen foam during day 1-5 with 40% from baseline, compared with 30% with the comparator (p<0.001). At day 43-47, the patients in the ibuprofen-foam group had a significant (p<0.05) reemergence of persistent pain and pain at dressing change (p<0.05) when the active dressing was changed to the comparator. Wound healing was similar in the ibuprofen foam and comparator group. No difference in adverse events between the comparator and the ibuprofen foam with local sustained release of low-dose ibuprofen was observed in this study. It was generally found that women reported less pain intensity than men, and pain intensity decreased with increasing age. In addition, pain intensity increased with initial pain intensity and increasing wound size. This study has demonstrated that the ibuprofen-foam dressing provided pain relief and reduced pain intensity without compromising healing or other safety parameters.

RESUMO

BACKGROUND: Fungi as a source of allergen are still largely neglected in basic research as well as in clinical practice. This study aimed to highlight the impact of fungal allergens in a group of patients suffering from atopic dermatitis (AD). AIMS AND OBJECTIVES: The evaluation of the sensitization to fungi in AD patients aged 14 year and older and the evaluation of the relation of fungal sensitization to the occurrence of other atopic diseases and parameters. MATERIALS AND METHODS: All patients satisfying inclusion criteria attending our hospital between 2008 and 2017 were included in the study. The complete dermatological and allergological examinations were performed in all included patients including examination of specific immunoglobulin E, skin prick test to mixture of fungi and inhalant allergens, evaluation of asthma bronchiale, rhinitis, onset of AD, family history about atopy, duration of eczematous lesions, severity of AD. Pairs of these categories were entered in the contingency tables and the Chi-square test for relationship of these variables was performed with the level of significance set below 5%. RESULTS: Three hundred and thirty-one patients were included in the study; the average age was 26.8 years. The sensitization to fungi was recorded in 100 patients (30%). In these patients, the occurrence of asthma bronchiale, rhinitis, family history about atopy, sensitization to grass and trees was significantly higher than in patients without sensitization to fungi. We did not find any significant relation between the sensitization to fungi and the severity of AD, no relation was also found between the sensitization to fungi and sensitization to mites, animal dander, bird feather, and dust. CONCLUSION: The occurrence of asthma bronchiale, rhinitis, family history about atopy, sensitization to grass and trees was significantly higher in AD patients with sensitization to fungi. No relation was found between the severity of AD and the sensitization to fungi.

RESUMO

BACKGROUND: In adult patients suffering from atopic dermatitis (AD), studies investigating the co-prevalence of AD and food allergy are still scarce, and exact data are not available. AIMS AND OBJECTIVES: To evaluate the occurrence of food allergy to peanuts in significant relation to food hypersensitivity, inhalant allergy and to asthma bronchial and rhinitis. MATERIALS AND METHODS: Altogether 332 patients of AD 14 year or older were included in the study. The complete dermatological and allergological examinations were performed in all included patients (including examination of specific immunoglobulin E, skin prick test to different food and inhalant allergens, anamnestic data about food reactions, evaluation of allergic rhinitis, and allergic asthma bronchiale). We evaluated whether there was some relation between the food allergy to peanuts and followed parameters. Pairs of these categories were entered in the contingency tables, and the Chi-square test for the relationship of these variables was performed with the level of significance set to 5%. RESULTS: Altogether 332 persons suffering from AD were included in the study of which 120 were male and 212 were female; the average age was 27.2 year. The significant relation between the allergy to peanuts and the occurrence of food hypersensitivity (FH) reactions to tomatoes, kiwi, apples, oranges, carrot and to the sensitization to grass, trees, mites, and the occurrence of rhinitis was found. CONCLUSION: The significant relation between the allergy to peanuts and the occurrence of FH reactions and the sensitization to inhalant allergens and rhinitis was found. The future studies may show if the decrease in food allergy to peanuts can lead to the decrease of the occurrence of other FH reactions and sensitization to inhalant allergens and rhinitis in AD patients.

RESUMO

Psoriasis is a chronic inflammatory skin disease which is often manifested during childhood. The present study investigated changes in the serum levels of proinflammatory cytokines and soluble forms of adhesion molecules in children with psoriasis. The observed patient group of 26 children was treated with the Goeckerman regimen. This therapy combines dermal application of crude coal tar with ultraviolet radiation. The Psoriasis Area Severity Index decreased significantly after treatment by with the Goeckerman regimen (p < 0.001). Serum levels of the proinflammatory cytokine TNF-alpha and adhesion molecules sICAM-1, sP-selectin and sE-selectin decreased after the Goeckerman regimen. The TNF-alpha and sICAM-1 decreased significantly (p < 0.05). Our findings support the complex role of these immune parameters in the immunopathogenesis of psoriasis in children. The serum level of IL-8 increased after the Goeckerman regimen. This fact indicates that the chemokine pathway of IL-8 activity could be modulated by this treatment, most likely by polycyclic aromatic hydrocarbons.
