Tacrolimus ointment 0.1% in pityriasis alba: an open-label, randomized, placebo-controlled study.

BACKGROUND: Pityriasis alba (PA) is a frequent reason for dermatological consultation because of its chronic course, tendency to relapse and aesthetic impact. OBJECTIVES: In view of its strong association with atopic dermatitis, the objective of this open-label study was to assess the efficacy and safety of tacrolimus ointment in the treatment of PA compared with the efficacy of moisturizers. PATIENTS/METHODS: The study population consisted of 60 individuals of phototype III or IV according to Fitzpatrick's classification, aged 6-21 years. Patients were randomly assigned to one of two groups. Subjects in group A were instructed to apply tacrolimus ointment 0.1% twice daily, 12 h apart, on all hypopigmented macules. Standard moisturizers with SPF 20 sunscreen were used on all lesions applied at least 30 min apart from the tacrolimus ointment. Subjects in group B used solely the same moisturizers with sunscreen. Hypopigmented areas were evaluated at baseline and weeks 0, 3, 6 and 9 by investigators for scaling, hypopigmentation and pruritus on a scale of 0-3. Patient satisfaction was also recorded on a scale of 0-3. All adverse effects were recorded. RESULTS: A statistically significant improvement through time, in hypopigmentation, pruritus and scaling was observed in both groups during the course of 9 weeks. Hypopigmentation resolved from a baseline score of 2.38+/-0.64 to 1.15+/-0.54 at week 3, 0.46+/-0.51 at week 6 and 0.00+/-0.00 at week 9 for the group applying tacrolimus ointment 0.1%. The difference in improvement between the two groups was statistically significant on all three assessments for hypopigmentation (P<0.001), and for pruritus on week 6 and 9 assessments (P<0.05). Three patients (11.5%) in the tacrolimus group reported a mild transient sensation of burning. All patients in the tacrolimus group reported they were completely satisfied or just satisfied with the treatment compared with only 50% of patients using the placebo. CONCLUSIONS: Tacrolimus ointment 0.1% appears to be an effective and safe treatment for PA.

Poikiloderma of Civatte: a clinical and epidemiological study.

BACKGROUND: Although a common dermatosis, idiopathic poikiloderma of the face and neck has not been studied in depth for decades. OBJECTIVES: To reassess the clinical and epidemiological characteristics of poikiloderma of Civatte (PC). MATERIAL AND METHODS: Fifty consecutive patients with PC. Evaluation included history taking and physical examination. Epidemiological and clinical parameters were recorded and analysed. The literature from 1923 until today, was reviewed thoroughly. RESULTS: The frequency of PC among dermatologic patients was estimated to be 1.4%. There were 34 females (68%) and 16 males in the present study. The mean age at diagnosis was 47.8 years for females and 61.7 years for males. The majority (88%) had skin phototype II or III. Among females, 26 were at their peri-menopausal stage, including three cases of iatrogenic menopause. Four patients reported that other blood-related family members also had PC. The v and the sides of the neck and the upper chest were most often affected in a symmetric distribution. The face (preauricular and parotid region) was involved in 19 patients (38%). The erythemato-telangiectatic clinical type predominated (58%), followed by the mixed (22%) and the pigmented type (20%). Almost half of the patients (46%) were symptomatic (itching, burning and 'flushing'). The mean duration from onset to diagnosis was 6.2 years according to the patients' report. The course was usually slowly progressive (82%) and irreversible. CONCLUSIONS: PC shows characteristic features, supporting the theory that it represents a distinct entity. It is rather common in Greece. Although menopausal women predominated in our cohort, men were not uncommonly affected and were diagnosed at an older age. Based on the predominating clinical feature, PC can be classified into three clinical forms. Symmetry and sparing of the anatomically shaded areas of the neck are highly characteristic for PC. Face involvement was not as common and as severe as it had been considered in the past. Recognition of clinical type is important for the selection of the most appropriate treatment, which, despite the advent of novel modalities, remains problematic.

Randomized placebo-controlled trial of a flavonoid-rich plant extract-based cream in the treatment of rosacea.

BACKGROUND: Biological research suggests that vascular changes may play a major role in rosacea pathogenesis. Chrysanthellum indicum is a plant-based extract containing a unique combination of phenylpropenoic acids, flavonoids and saponosids, and has a well-documented effect on vascular wall permeability and increase of the mechanical resistance of capillaries. OBJECTIVE: To determine the efficacy and safety of a cream containing 1%C. indicum extract with vitamin P properties in the treatment of rosacea. METHODS: This study included 246 patients diagnosed clinically as having moderate rosacea. Patients were randomly allocated to C. indicum extract-based cream (n = 125) and placebo (n = 121) groups. Patients were advised to apply the products on their face twice a day for a 12-week period. The patients were examined at the end of each 4-week period. Severity of erythema (graded by reference to six photographs), surface of erythema and rosacea overall severity scores were recorded at each visit on days 0, 28, 56 and 84. Investigators carried out a final efficacy assessment at the end of week 12. Volunteers' final overall efficacy assessment was recorded in a self-administered questionnaire. Adverse events were identified through examination, interview and collection of comments in patients' questionnaires. RESULTS: Treatment with the C. indicum extract-based cream resulted in significant improvement (P < 0.05) in severity of erythema, overall rosacea severity compared to baseline and placebo, and investigator and patient overall efficacy assessment scores (P = 0.046 and P = 0.001, respectively) compared with placebo scores. Adverse reactions were mild, and did not differ between the C. indicum extract-based cream and the placebo groups. CONCLUSION: Chrysanthellum indicum extract-based cream is an effective and well-tolerated topical agent for the treatment of moderate rosacea. The mode of action of the active ingredient suggests that additional efficacy might be expected from combination with other topical treatments.

Pimecrolimus cream 1% vs. betamethasone 17-valerate 0.1% cream in the treatment of seborrhoeic dermatitis. A randomized open-label clinical trial.

BACKGROUND: Seborrhoeic dermatitis is a chronic inflammatory disease with remissions and exacerbations, characterized by erythema, scaling and pruritus primarily on the face, scalp and chest. Corticosteroids and antifungals are the mainstay of therapy. However, chronic use of corticosteroids is associated with side-effects such as skin atrophy and telangiectasia. Pimecrolimus, an inhibitor of calcineurin, has been used successfully in one patient with seborrhoeic dermatitis. OBJECTIVES: The objective of this randomized open-label clinical trial was to compare the efficacy and tolerability of pimecrolimus in comparison with a potent corticosteroid (betamethasone 17-valerate) in the treatment of seborrhoeic dermatitis. METHODS: Twenty patients with seborrhoeic dermatitis were included in this study, 11 patients in the pimecrolimus 1% cream group and nine patients in the betamethasone 17-valerate 0.1% cream group. Patients were instructed to use a thin layer of the study products twice daily at the lesional area and to discontinue treatment as soon as symptoms were absent. Clinical measures assessed were erythema, scaling and pruritus which were evaluated using a four-point scale (0-3). RESULTS: Both pimecrolimus and betamethasone were highly effective in the treatment of seborrhoeic dermatitis. Betamethasone reduced all three parameters, erythema, scaling and pruritus, faster than pimecrolimus, but the differences in reduction were not statistically significant. Relapses were observed more frequently and were more severe with betamethasone than with pimecrolimus. Moreover, pruritus was not observed after discontinuation of treatment from day 15 and beyond in the pimecrolimus group, whereas it was reported in most patients of the betamethasone group. This difference was statistically significant. CONCLUSIONS: It appears that pimecrolimus, a nonsteroidal topical treatment, may be an excellent alternative therapeutic modality for treating seborrhoeic dermatitis.

Asymptomatic sensitisation to grapes in a sample of workers in the wine industry.

AIMS: To assess the prevalence of sensitisation to grapes (Vitis vinifera var. agiorghitiko) in a population with repeated exposure to grape allergens through direct cutaneous contact as well as through the gastrointestinal tract. METHODS: One hundred and twenty subjects were enrolled in each of four groups: grape harvesters, winery workers in selection of grapes, winery workers operating de-stemming/crushing/pressing machines, and administrative personnel. Sensitisation to grapes was examined by skin prick-to-prick tests with fresh fruit and juice. RESULTS: Eight harvesters and five workers in grape selection had positive reaction to the grapes tested. No machine operators or administrative personnel had positive tests. The likelihood of sensitisation was estimated at 3.7% per year of occupation by logistic regression analysis. None of the employees reported symptoms associated with sensitisation to grapes. CONCLUSION: Asymptomatic sensitisation to grapes was detected only in workers handling the fruit, suggesting that sensitisation is more likely to occur through cutaneous exposure and/or minor wounding than through the gastrointestinal tract. Prevalence rates were high and the clinical impact needs to be further investigated.

A randomized trial of amorolfine 5% solution nail lacquer in association with itraconazole pulse therapy compared with itraconazole alone in the treatment of Candida fingernail onychomycosis.

BACKGROUND: Treatment failures and relapses are not uncommon in onychomycosis. Therefore, it is worthwhile to consider the combination of systemic and topical antifungals to improve the cure rates further and to reduce the duration of systemic treatment. OBJECTIVES: To evaluate and compare itraconazole pulse therapy combined with amorolfine with itraconazole alone in the treatment of Candida fingernail onychomycosis. METHODS: Ninety patients with moderate to severe Candida fingernail onychomycosis were randomized into two treatment groups of 45 subjects each. Group 1 received itraconazole pulse therapy for 2 months and applied amorolfine 5% solution nail lacquer for 6 months, while group 2 received monotherapy with three pulses of itraconazole. The primary efficacy criterion was the result of mycological examination at 3 months. The secondary criterion was the combined mycological and clinical response at 9 months. A pharmacoeconomic analysis was also performed to compare the cost-effectiveness of combined therapy vs. monotherapy. RESULTS: Eighty-five patients were analysed (73 women and 12 men, mean +/- SD age 44.2 +/- 12.9 years). Patients had a mean +/- SD of 3.64 +/- 2.0 nails involved and 228.6 +/- 148.0 mm2 of their nail surface diseased. The mean duration of onychomycosis was 11 months. Paronychial involvement was evident in 71 patients. C. albicans was isolated in 85 cases, C. parapsilosis in three and other Candida species in two cases. Side-effects were uncommon and in only one case led to withdrawal. At the 3-month visit, mycological cure was seen in 32 (74%) of 43 patients in group 1 and in 25 (60%) of 42 patients in group 2. At the 9-month visit, a global cure was seen in 40 patients (93%) in group 1 and in 34 patients (81%) in group 2. Statistical analysis showed no statistically significant difference (P > 0.1) between the two treatment groups. The cost per cure ratio was 1.63 and 1.70euro for groups 1 and 2, respectively. CONCLUSIONS: The combination of amorolfine and oral itraconazole, which interfere with different steps of ergosterol synthesis, exhibited substantial synergy. Compared with oral itraconazole alone, the combination achieved greater mycological cure and increased total cure rate. However, no statistically significant difference was documented for this number of observations. Combination treatment with amorolfine and two pulses of itraconazole is at least as safe and effective as three pulses of itraconazole, with a lower cost per patient. In our opinion, the addition of amorolfine to oral itraconazole pulse therapy is of value in the treatment of moderate to severe Candida fingernail onychomycosis.

Contact reactions to fragrances.

BACKGROUND: The most common reaction to fragrances is contact dermatitis, a delayed hypersensitivity reaction; however, other reactions include immediate contact reactions (contact urticaria) and photo-allergic reactions. Fragrance mix (FM) and balsam of Peru (BP) are used to screen for fragrance allergy. OBJECTIVE: To study the different types of allergic skin reactions to fragrance compounds. METHODS: Delayed hypersensitivity reactions to FM and BP were studied in 4,975 patients with suspected contact dermatitis by routine patch testing interpreted at 48 and 96 hours. In 664 of the patients, patch tests were read at 30 minutes to evaluate for immediate (wheal-and-flare) contact reactions and again at 48 and 96 hours. Photopatch tests to FM were performed in 111 patients with suspected photo-allergic dermatitis. RESULTS: Delayed contact reactions to FM occurred in 6.6% of females and 5.4% of males and to BP in 3.9% of females and 4.1% of males. Analysis of data over time (12 study years) showed an increased trend for reactions to fragrances, particularly in males. Sensitivity to other contact allergens (polysensitivity) was found in 62% of patients and polysensitivity presented more often with generalized contact dermatitis. The most sensitizing components of the fragrance mix that were tested in 38 patients were cinnamic alcohol, oak moss, and cinnamic aldehyde. There were 112 immediate patch test reactions to FM and 113 to BP in 664 patients. Immediate contact reactions were followed by delayed contact reactions in 13.4% of patients for FM and 8.8% for BP, representing a significant increase in the frequency of delayed contact reactions. Patients with immediate contact reactions to fragrances did not have a higher incidence of atopy (25.9%). No cases of positive photopatch test reactions to FM were seen. CONCLUSION: Fragrances commonly cause both delayed and immediate patch test reactions and patients with immediate contact reactions have an increase in delayed contact reactions to the same allergen.

Frequency of immediate reactions to the European standard series.

Immediate contact reactions (contact urticaria) can occur after skin contact with a wide range of substances. We studied the incidence of immediate contact reactions (wheal and flare) to the European standard series allergens in 664 patients. Patch tests were first examined at 30 min for immediate patch test (IPT) reactions, and again at D2 and D4 for delayed patch test (DPT) reactions. Almost all the allergens of the European standard series caused IPT reactions. IPT reactions were most commonly seen with Myroxylon Pereirae (balsam of Peru) (113 reactions), fragrance mix (112 reactions), paraben mix (30 reactions) and clioquinol (13 reactions); these reactions were followed by DPT reactions to the same substance in 13.4%, 8.8%, 10% and 7.7%, respectively. For certain substances, patients with (+) IPT reactions had a significantly higher incidence of DPT reactions to the same allergen, as compared to patients with (-) IPT reactions (fragrance compounds p<0.001, formaldehyde p<0.005, thiuram mix p<0.01, paraben mix p<0.05). Thus, perhaps the mechanisms involved in IPT reactions are not the same for all substances. At least for certain substances, an IPT reaction may be related to the development of a DPT reaction.

A study of the effect of theophylline on the anti-inflammatory potency of dexamethasone using alpha-aminoisobutyric acid uptake in rat skin fibroblasts: a possible mechanism through the glucocorticoid receptor.

The action of theophylline on the uptake of alpha-aminoisobutyric acid (AIB; an indicator of anti-inflammatory potency) stimulated by the glucocorticoid, dexamethasone, in cultured rat fibroblast monolayers was evaluated. Theophylline alone (0.1 m m) did not show significant activity (3314+/-27 cpm) compared with the baseline level (3186+/-130 cpm), but in the presence of 10 n m dexamethasone the stimulation of AIB uptake was increased to 5263+/-100 cpm, approximately to the same extent as with 100 n m dexamethasone alone (5397+/-28 cpm). Activation of glucocorticoid-receptor complexes in rat fibroblast cytosol was studied by assessing the extent of their binding to DNA-cellulose. Activated and non-activated forms of glucocorticoid-receptor complexes were analysed by DEAE-Sephadex chromatography. Theophylline (1 m m) was found to have a direct effect (0 degrees C), similar to that of heat (25 degrees C) on DNA-cellulose binding, that is approximately 64.5% and 68.7%, respectively, thus indicating that theophylline promotes activation of glucocorticoid receptors at low temperature. The effect of theophylline on the stimulation of AIB uptake by dexamethasone when considered in the light of its activation of GR receptors in the fibroblast cytosol indicates that this effect may be mediated by GR activation.

Anaphylaxis induced by lentils.

BACKGROUND: The legume food family is large and includes peanut and soybean, two of the most frequent causes of food allergy. Literature on type I hypersensitivity to lentils, also a legume, is scarce. OBJECTIVE: To describe a child with repeated anaphylactic reactions related to lentils. METHODS: Skin prick tests with both commercial and cooked extracts and serum-specific IgE measured by CAP-RIA were used to identify specific IgE antibodies to various legumes. RESULTS: An 8-year-old girl suffered four episodes of anaphylaxis related to lentils from ages 3 to 7 years. The first three involved ingestion of cooked lentils and each time smaller amounts induced symptoms. The fourth episode occurred with inhalation exposure to cooking lentil soup. Subsequently, she presented with contact urticaria from raw chickpeas and an anaphylactic reaction after ingestion of cooked chickpeas. Prick tests showed strongly positive reactions to lentil and chickpea and weaker positive reactions to peanut, pea, soybean, and white bean. CAP-RIA was class 6 to lentil; class 5 to peanut, pea, and soybean; class 4 to white bean, and class 0 to green bean. CONCLUSION: Severe type I hypersensitivity to lentils occurred in this patient and was associated with clinically relevant hypersensitivity to chickpeas. Prick tests and CAP-RIA demonstrated multiple positive reactions to other legumes.

Influence of the menstrual cycle on skin-prick test reactions to histamine, morphine and allergen.

The purpose of this study was to examine the possible influence of the phases of the menstrual cycle on dermal reactivity to skin-prick testing. We studied 15 atopic, menstruating women with seasonal rhinoconjunctivitis and/or asthma, with known sensitivity to olive and parietaria (mean age 25.2 years) and 15 non-atopic, healthy, female controls (mean age 24.7 years). Skin-prick tests with histamine, morphine, and in the atopic group with parietaria/and/or olive, were repeated three times during the same menstrual cycle, corresponding to bleeding (day 1-4), midcycle (day 12-16) and the late progesterone phase (day 24-28). None of the patients had received oral antihistamines or exogenous hormones for at least 1 month prior to testing. Results indicate a significant increase in weal-and-flare size to histamine, morphine, and parietaria on days 12-16 of the cycle, corresponding to ovulation and peak oestrogen levels. This was observed in both atopic and non-atopic women. Differences in skin reactivity to histamine and morphine between the groups were not significant. Therefore, in women, the phase of the menstrual cycle is another factor that may influence skin-test results.
