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.

Pyogenic granulomas following topical application of tretinoin.
Topical tretinoin is used in the treatment of acne and other dermatoses. The most common side-effects are itching, dryness and reddening of the skin. We report an additional cutaneous reaction, which occurred in patients using topical tretinoin. Pyogenic granulomas developed in two patients with acne and in one with dermatofibroma following application of tretinoin. The granulomas grew on the lesions after 2-3 weeks of therapy initiation. All patients were men and the granulomas developed in their trunk. The lesions resolved when topical tretinoin was ceased. Although the number of patients reported is too small to estimate the true incidence of this reaction, it is likely that dermatologists will encounter similar reactions in patients treated with topical tretinoin for acne or other reasons.

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.

Comparison of chloroxylenol 0.5% plus salicylic acid 2% cream and benzoyl peroxide 5% gel in the treatment of acne vulgaris: a randomized double-blind study.
A 12-week double-blind randomized study was performed to compare benzoyl peroxide 5% (BP) gel and chloroxylenol 0.5% plus salicylic acid 2% (PCMX + SA) cream (Nisal cream) for efficacy and adverse reactions. Thirty-seven volunteers participated in the study, 19 in the BP group and 18 in the PCMX + SA group. The patients applied the medication twice daily to the entire face. Clinical evaluation and lesion counts were obtained at 0, 3, 6, 9 and 12 weeks. At week 12 both groups showed a marked improvement in both inflammatory and noninflammatory lesions (60% and 54% for the BP group and 62% and 56% for and 56% for the PCMX + SA group, respectively). Although PCMX + SA showed a slightly stronger keratolytic effect throughout the study period, there was no statistically significant difference in the reduction of the papulopustules or comedones between the two groups. Adverse effects such as erythema and photosensitivity were significantly fewer in the PCMX + SA group at week 12 (p = 0.0002 and p = 0.05, respectively). These results suggest that PCMX + SA cream is as effective as BP gel in the treatment of papulopustular and comedonal acne and that it is better tolerated.

Topical adapalene gel 0.1% vs. isotretinoin gel 0.05% in the treatment of acne vulgaris: a randomized open-label clinical trial.
BACKGROUND: Topical application of isotretinoin and adapalene has proved effective in treating acne vulgaris. Both drugs demonstrate therapeutic advantages and less irritancy over tretinoin, the most widely used treatment for acne. They both act as retinoid agonists, but differ in their affinity profile for nuclear and cytosolic retinoic acid receptors. OBJECTIVE: To compare the efficacy and tolerability of adapalene gel 0.1% and isotretinoin gel 0.05% in the treatment of acne vulgaris of the face, in a randomized open-label clinical trial. METHODS: Eighty patients were enrolled and were instructed to apply adapalene gel 0.1% or isotretinoin gel 0.05% once daily over a 12-week treatment period. Efficacy determination included noninflammatory and inflammatory lesion counts by the investigator and global evaluation of improvement. Cutaneous tolerance was assessed by determining erythema, scaling and burning with pruritus. RESULTS: Adapalene and isotretinoin gels were highly effective in treating facial acne. Adapalene gel produced greater reductions in noninflammatory and inflammatory lesion counts than did isotretinoin gel, but differences between treatments were not statistically significant. Adapalene gel was significantly better tolerated than isotretinoin gel during the whole treatment period. CONCLUSIONS: The two gels studied demonstrated comparable efficacy. When adapalene and isotretinoin were compared, significantly lower skin irritation was noted with adapalene, indicating that adapalene may begin a new era of treatment with low-irritant retinoids.

Expression of SS-A/Ro and SS-B/La antigens in skin biopsy specimens of patients with photosensitive forms of lupus erythematosus.
CONTEXT: The reason that only some patients with lupus erythematosus (LE) develop autoantibodies to SS-A/Ro and SS-B/La antigens and photosensitivity is unknown. One hypothesis is that both events are related to the level of expression of these antigens in the skin. OBJECTIVE AND DESIGN: To test this hypothesis, we measured the expression of the 52-kd SS-A/Ro, 60-kd SS-A/Ro, and 48-kd SS-B/La antigens in normal sun-protected and sun-exposed skin in 14 patients with LE with photosensitivity, 12 patients with LE without photosensitivity, and 4 normal individuals. The presence of circulating antibodies to these antigens was measured in all patients. SETTING: Outpatient clinic in an academic medical center. RESULTS: We found that the expression of the 52-kd SS-A/Ro, 60-kd SS-A/Ro, and 48-kd SS-B/La antigens in skin biopsy specimens obtained from the same site was 4- to 10-fold higher in patients with LE with photosensitivity than in those patients with LE without photosensitivity (P<.001). Antigen expression was highly correlated with the presence and titer of circulating anti-SS-A/Ro and anti-SS-B/La antibodies (P<.001). CONCLUSIONS: These findings indicate that photosensitivity and the presence and titer of circulating anti-SS-A/Ro and anti-SS-B/La antibodies are both directly correlated with the expression of accessible and immunoreactive SS-A/Ro and SS-B/La antigens in the skin specimens of patients with LE. Thus, the expression of these antigens in keratinocytes may be an important determinant of the development of both SS-A/Ro and SS-B/La autoantibodies and of photosensitive forms of LE.

Ineffectiveness of cyclosporine as an adjuvant to corticosteroids in the treatment of pemphigus.
OBJECTIVE: To compare the effectiveness and the adverse effects of 2 different regimens for the treatment of pemphigus: corticosteroids alone compared with a combination of corticosteroids and cyclosporine. DESIGN: Concurrently randomized trial. SETTING: Tertiary care medical center. PATIENTS AND METHODS: We studied 33 sequential hospitalized patients with newly diagnosed pemphigus vulgaris (n=29) or pemphigus foliaceous (n=4) based on clinical, histological, and immunofluorescence criteria who had not previously been treated with systemic corticosteroids or immununosuppressive drugs. Patients were randomly assigned to treatment with methylprednisolone or prednisolone plus cyclosporine. INTERVENTION: Both groups were treated with similar initial doses of prednisolone (prednisone equivalent, 1 mg/kg), which were increased 50% every 5 to 10 days based on persistence of disease activity. One group was treated in addition with cyclosporine (5 mg/kg). MAIN OUTCOME MEASURES: Patients were followed up closely for clinical outcome based on time required to control active manifestations of the disease, induction of partial and complete remissions, total amount of corticosteroids administered, frequency of relapses, and development of complications. RESULTS: The 2 groups were similar in terms of demographics and baseline disease severity. There was no difference between groups in any of the variables used to measure response to treatment or total amount of corticosteroids administered. Complications were more common in patients who received combination therapy. CONCLUSION: Combination treatment with corticosteroids and cyclosporine, 5 mg/kg, offers no advantage over treatment with corticosteroids alone in patients with pemphigus.

Double-blind clinical study reveals synergistic action between alpha-hydroxy acid and betamethasone lotions towards topical treatment of scalp psoriasis.
OBJECTIVE: A double-blind, single-site, split-face clinical study was organized and carried out in order to evaluate the efficacy, tolerability, and safety of a glycolic acid containing scalp lotion in conjunction with a betamethasone (as the 17-valerate) scalp application against conditions of psoriasis. BACKGROUND: Alpha-hydroxy acids (AHA) have been proposed as therapeutic modalities against skin exfoliative conditions such as ichthyosis, xeroderma, and psoriasis. AHAs are hereby clinically investigated as therapeutic modalities adjuvant to corticosteroids in order to diminish systemic and topical adverse side-effects most frequently associated with use of the latter. METHODS: Twenty patients suffering from scalp psoriasis and other psoriatic conditions were included in a double-blind, split-face clinical study, using combinations of a 10% (w/w) glycolic acid scalp lotion, placebo lotion (excipients only), and a 0.1% (w/w) betamethasone scalp application, applied twice daily without any bandage for a period of 8 weeks. Clinical assessments were carried out by highly experienced physician evaluations based on a four-grade scale, prior to treatment and after 2, 4, 6 and 8 weeks. RESULTS: Improvement was observed in all cases included in the study following treatment with the 10% glycolic acid lotion. However, when equal parts of the 0.1% betamethasone lotion were combined, most of the treated sites were healed. Moreover, the duration of treatment required for healing was in this case reduced to approximately half of that needed when the glycolic acid or the betamethasone lotions were used separately for treatment. CONCLUSIONS: The present clinical study demonstrates for the first time that the effective and well tolerated therapeutic efficacy of glycolic acid scalp lotions is enhanced when used in conjunction with a 0.1% betamethasone scalp application against scalp psoriasis. This potential offers the practising dermatologist with novel treatment modes against severe skin conditions by combining topical corticosteroid with exfoliative agent therapy.

Plasmapheresis in toxic epidermal necrolysis.
BACKGROUND: The treatment of toxic epidermal necrolysis (TEN) is usually based on the removal of the offending drug(s), fluid replacement, nutritional support, and local management. The mortality and morbidity, however, remain high and the death rate may be reduced to 10% only in special centers that use biologic dressings. Plasma exchange (PE) was proven efficacious in small series of patients and of no particular value in others. METHODS: Seven patients suffering from severe TEN covering 30%-80% of body surface area and having two or four mucous membranes involved, were included in this open study. Malignancy (Hodgkin's disease, brain tumor) and a variety of medicaments (carbamazepine, allopurinol, diphenylhydantoin, cefaclor, amoxicyllin with clavullanic acid) were considered as causally implicated. One to four PEs of 2.5 L were given on alternate days in six patients and on a daily basis in the seventh. RESULTS: All patients recovered successfully from their disease. No new lesions appeared after the first PE in four patients. Neither adverse reactions from this therapy nor sequelae from TEN were observed after a long follow-up lasting up to 8 years. CONCLUSIONS: Although PE is expensive and requires easy venous access to be performed, it could be listed in the first line of TEN therapy. The method is safe and efficacious, providing prompt relief from pain and rapid cessation of necrolysis. The alternate day PEs are considered preferable to the everyday regimen.

Heterogeneity in the expression of Ro and La antigens in human skin.
OBJECTIVE: To determine whether there are variations in the expression of Ro and La antigens in human skin. METHODS: Levels of expression of Ro and/or La antigens in 26 specimens of normal human skin (11 sun-exposed, 15 sun-protected) were measured by indirect immunofluorescence with monospecific antisera. RESULTS: Levels of expression of both antigens varied by more than 2,000-fold in the skin of different individuals. There usually was a correlation between the levels of expression of Ro and La antigens in the same skin specimen. There was no correlation found between the levels of Ro or La antigen expression and sun exposure, nor was there a correlation found between levels of antigen expression and location of the skin on the body. CONCLUSION: There is a marked heterogeneity in the expression of both Ro and La antigens in the skin of different individuals. The present study findings suggest that the levels of expression of these antigens may play a role in the propensity of some individuals to develop anti-Ro or anti-La antibodies and/or skin lesions associated with the presence of these antibodies.

Association of acanthosis nigricans with insulin resistance in patients with polycystic ovary syndrome.
This study was designed to explore the association of insulin resistance and acanthosis nigricans (AN) in patients with polycystic ovary syndrome (PCOS). Fifty women, 18-37 years old, were included in the study, and divided into five groups consisting of: (I) 10 women with PCOS, abnormal body mass index (BMI) and AN; (II) 10 women with PCOS and abnormal BMI, but without AN; (III) 10 women with PCOS, normal BMI, and no AN; (IV) 10 women with abnormal BMI, but without PCOS or AN; and (V) 10 healthy women with normal BMI. Measurement of fasting glucose and insulin levels before and after oral glucose challenge was performed. Fasting serum insulin levels were found to be significantly lower in groups III, IV and V than in groups I and II, with no significant difference between groups I and II, or between groups III, IV and V. Total insulin response following administration of glucose did not differ significantly between the groups. These findings support the view that obese PCOS patients with AN do not have significantly higher insulin resistance than obese patients without AN. Insulin resistance is a necessary, but not the only, factor leading to the development of AN in patients with PCOS. Other factors should also be considered in the pathogenesis of this cutaneous reaction.

Treatment of oral pemphigus vulgaris.
BACKGROUND: Oral pemphigus is considered to represent either an initial stage of pemphigus vulgaris that should be treated with high doses of immunosuppressive drugs to prevent its spread to the skin or a variety of the disease that does not need aggressive treatment. The absence of a widely accepted therapeutic method and the obscure nature of this disease prompted this study. METHODS: Twenty-eight patients with oral pemphigus were randomly divided into three groups. The first group received only steroids at a dose of 40 mg of prednisone equivalent. In the other two groups the same dose of steroids was administered, but combined with either 100 mg of cyclophosphamide or 5 mg/kg of cyclosporine as an adjuvant. Direct immunofluorescence studies were performed on specimens obtained from both buccal mucosa and oral skin. RESULTS: There was no significant difference in the duration of treatment required to achieve remission and in the relapse rate among the three groups. The incidence of complications was higher with combination treatment. Deposited immunoreactants were detected with equal frequency in specimens obtained from the buccal mucosa and normal skin. CONCLUSIONS: Oral pemphigus most likely represents an initial stage of a disease that can become generalized. Administration of moderate doses of steroids alone is effective in controlling the disease.
