Effective treatment is not currently available for suppressing the recurrence of genital herpes simplex virus (HSV) infections. Since intravenous immunoglobulins (IVIG) proved useful against HSV in experimental models, we treated patients with very high frequency of HSV genital recurrences (more than 15 episodes per year) with IVIG (400 mg/Kg every fourth week). The control group was treated with intermittent oral acyclovir (800 mg twice a day for one week every month). Both groups were treated for six months and, then, patients were followed-up to further six months. Both IVIG and acyclovir were effective in reducing the frequency of HSV genital recurrences as compared to base-line. However, patients treated with IVIG had a more striking reduction in the frequency of recurrences as well as both a shorter mean duration and a minor severity of the lesions as compared to acyclovir-treated patients. Furthermore, we found a trend indicating IVIG as more effective in reducing the viral load. Since in IVIG-recipients we found a strong increase of peripheral blood lymphocytes with natural killer (NK) surface phenotype, we suggest that the clinical effectiveness of IVIG treatment is probably mediated via the expansion of NK cell populations. Our study indicates that the treatment with IVIG is an effective and safe tool for suppressing the recurrences of genital HSV infections.
Topical corticosteroids are commonly used for the short-term management of seborrhoeic dermatitis (SD) of the scalp. The aim of this study was to evaluate the effectiveness, tolerance and cosmetic acceptability of desonide 0.05% solution, whose alcohol-free formulation is innovative with respect to traditional corticosteroid lotions, in the treatment of SD of the scalp. For this purpose, 155 adult subjects applied on scalp lesions desonide once daily for 1 week, on alternate days for 3 weeks, and two times a week for 4 weeks. A significant reduction of the severity of erythema, scaling and pruritus was observed (P<0.001). Interestingly, during the phase of gradual reduction of weekly applications, results were frequently maintained or improved further. Twenty patients (13%) at 4 weeks and 85 patients (58%) at 8 weeks had their scalp SD cleared. Most patients regarded the overall effectiveness, tolerability and acceptability as satisfactory; patients who had previously used common steroid lotions expressed a positive judgment on desonide solution compared to the other lotions in terms of efficacy, acceptability, rapidity of action, tolerability and persistence of effects. In conclusion, our preliminary findings indicate that desonide 0.05% solution is suitable for the short-term management of scalp SD.
Treatment of cheilitis is usually difficult and often disappointing. We evaluated the effects of a topical preparation containing vitamin E acetate (VEA® lipogel) in 254 patients (mean age, 29.5) with cheilitis of various nature and etiology, involving the vermilion region and/or the perioral skin. The most frequent form of cheilitis was that induced by oral isotretinoin; other forms were irritant contact dermatitis, atopic cheilitis, and contact allergy. Patients were instructed to apply VEA® lipogel daily; the number of daily applications was modulated on the basis of the severity of symptoms (two or three times a day in the majority of cases). After 4 weeks of treatment, clinical examination showed that the severity of symptoms and signs significantly improved (P<0.001). The response to treatment was reported as particularly rapid by 32% of patients. Patient's assessment of overall effectiveness and acceptability was positive in the majority of cases. Treatment was well tolerated; local adverse reactions were observed in 2.75% of patients and were mostly transient and mild. Our experience suggests that VEA® lipogel is an effective and safe approach to cheilitis. The safety of this preparation is also due to the presence of only a few excipients and the absence of fragrances, preservatives and colouring agents.
In order to evaluate the effect of Cyclosporin-A (CyA) at doses of 5 mg/kg per day in atopic dermatitis we studied clinical effects, immunoglobulin production, lymphocytes subset, immunphenotype and local cytokine production in seven patients before and after 3 months CyA therapy. Clinically CyA was very effective in eliminating pruritus, erythema and vescicles with no significant adverse side effects. Using flow cytometric analysis we demonstrated that CyA treatment restored an overcxpression of circulating CD25-positive cells. Similar results have been recorded with HLA-DR expression. CyA normalized the number of CD29 cells which were reduced in the blood of patients before starting treatment. Furthermore, after treatment, several eytokines (IL-2, IL-la and IL-l^) had diasappeared from the epidermis.
