Calcipotriol vs. tazarotene as combination therapy with narrowband ultraviolet B (311 nm): efficacy in patients with severe psoriasis.

BACKGROUND: Phototherapy has been shown to be one of the most effective treatment modalities for patients with psoriasis. Nevertheless, photocombination therapies capable both of reducing cumulative ultraviolet (UV) doses and of accelerating clearance of skin lesions are important and of high interest. There have been no published studies comparing the effect of narrowband UVB irradiation in combination with topical application of tazarotene vs. calcipotriol. OBJECTIVES: To determine, in a half-side manner, whether a combination of UVB (311 nm) and tazarotene is superior to UVB (311 nm) plus calcipotriol or vice versa. METHODS: Ten patients suffering from widespread symmetrical psoriasis were treated for at least 4 weeks with topical calcipotriol and tazarotene in a half-side distribution. Additionally, the whole body was irradiated with narrowband UVB (311 nm) four times a week. Before treatment and once weekly during therapy a modified Psoriasis Area and Severity Index was estimated for each body half. The total treatment time, number of treatment sessions and cumulative UVB dose necessary for clearance of skin lesions were determined in an observer-blind fashion for each patient. Furthermore, all patients completed a quality of life questionnaire. RESULTS: Clearance of psoriasis was observed after a median of 19 treatment sessions (range 14-28) and a median cumulative UVB dose of 22.98 J cm-2 (range 9.24-58.22) simultaneously for both body halves. On the side treated with topical tazarotene gel, four patients complained of itching and dryness of the skin, and skin irritation was observed in three of them. Six patients preferred the application of tazarotene gel, while four preferred calcipotriol. CONCLUSIONS: Our clinical comparison of narrowband UVB with either topical calcipotriol or topical tazarotene revealed no significant therapeutic difference between both regimens. Although these results need to be confirmed in larger patient groups, we feel that both photocombination therapies can broaden the therapeutic options for moderate to severe psoriasis vulgaris and may reduce the cumulative UVB dose during therapy.

Treatment of chronic plaque-stage psoriasis and psoriatic arthritis with mycophenolate mofetil.

Mycophenolate mofetil (MMF), a widely used immunosuppressant in organ transplantation, is a recent addition to the therapeutic armamentarium of autoimmune and inflammatory skin disorders in dermatology. We describe 5 patients with moderate to severe chronic plaque psoriasis and 6 patients with psoriatic arthritis that was refractory to conventional systemic and/or topical antipsoriatic treatment who were treated with MMF monotherapy (2 g/d) in a 10-week study. Although MMF was tolerated well in all patients, only patients with moderate psoriasis and psoriatic arthritis improved with therapy, whereas patients with severe psoriasis did not respond to MMF. Although MMF seems to be effective and safe for blistering autoimmune diseases and pyoderma gangrenosum, our data do not allow optimistic statements on the use of MMF in severe plaque-stage psoriasis. However, MMF may develop into an interesting therapeutic alternative for patients with psoriatic arthritis.

Quantitation of herpes simplex DNA in blood during aciclovir therapy with competitive PCR ELISA.

BACKGROUND: Monitoring viral load in blood has already been introduced into clinical routine for human immunodeficiency virus and hepatitis C virus. OBJECTIVE: This study was conducted to monitor the decline of herpes simplex (HSV) viral load in the blood of a patient with gingivostomatitis herpetica prior and during acyclovir therapy. METHODS: Analysis was done by quantitative PCR ELISA using an internal quantitation standard. RESULTS: Copy numbers were 66/microl blood prior to therapy, 60 during oral medication with valaciclovir, 97 and 72 copies/microl blood during the first 2 days of intravenous acyclovir therapy, followed by a sharp decline to 8 and 9 copies on days 3 and 4. During the following days, HSV was no longer detectable. CONCLUSION: As this quantitative approach can be easily adjusted to any other PCR, it provides a reliable, easy-to-apply method for monitoring therapy, also during new antiviral clinical trials.

[Severe course of a mutilating pansclerotic circumscribed scleroderma in childhood. Clinical aspects and therapy].

Disabling pansclerotic morphea of childhood is the most severe variant of localized scleroderma. It is characterized by rapid progression of deep cutaneous fibrosis expanding over large areas of body surface. The prognosis in terms of normal life activity is poor and the disease may even take a fatal course. Presented is a case with extremely severe and rapidly progressive lesions resulting in cutaneous ulcerations joint contractures, and multilaing deformities of the extremities. Histopathological analysis revealed extensive intravascular calcinosis of the small vessels, which may be an important factor in the pathogenesis of this poorly understood disease. UVA1-phototherapy was performed and induced a softening of sclerosis and a distinct decrease of skin thickness. Based on these observations UVA1-phototherapy may be promising in the treatment of extensive sclerotic disease of this kind, and possibly other diseases accompanied by excessive sclerosis.

Mycophenolate mofetil: a new therapeutic option in the treatment of blistering autoimmune diseases.

BACKGROUND: Mycophenolate mofetil (MMF), an ester of mycophenolic acid (MPA), was approved by the Food and Drug Administration in 1995 and is currently primarily indicated for the prophylaxis of rejection in renal transplant patients. The drug seems also to be of value in the treatment of psoriasis and rheumatic arthritis. Recently there have been 6 reported cases of successful treatment of blistering autoimmune diseases with MMF in combination with high dose prednisone therapy. OBJECTIVE: On the basis of these reports we administered this new treatment regimen to several patients with blistering autoimmune diseases. Besides using a combination of MMF and high-dose prednisone we wanted to evaluate whether MMF monotherapy is also effective in the treatment of blistering autoimmune diseases. METHODS: We administered MMF to 5 patients who had severe pemphigus vulgaris or bullous pemphigoid. Two patients received MMF in combination with high-dose prednisone therapy and 3 patients received MMF monotherapy. To our knowledge, this is the first report of successful treatment of pemphigus vulgaris and bullous pemphigoid with MMF monotherapy. RESULTS: All patients were completely free of symptoms within 8 to 11 weeks of therapy. Patients who had received MMF monotherapy responded as well to treatment as those who received a combination of MMF and high-dose prednisone. CONCLUSION: Our experiences strongly suggest that MMF monotherapy may be effective for patients even with severe pemphigus vulgaris and bullous pemphigoid. In addition, MMF monotherapy, at least over the short term, offers the advantage of fewer side effects in comparison to immunosuppressive combination therapy and was well tolerated by our patients.

Phototherapy for atopic eczema with narrow-band UVB.

Management of atopic dermatitis has been less than satisfactory. Conventional therapy has not been particularly successful, and prolonged use of topical corticosteroids and systemic immunosuppressant drugs (eg, corticosteroids, cyclosporine, azathioprine) can result in severe cutaneous and systemic effects. We decided to evaluate the effect of UVB at 311 nm to treat 5 patients with moderate to severe atopic dermatitis. In each patient a mean cumulative dose of 9.2 J/cm2 was applied over a mean of 19 irradiations. Narrow-band UVB notably reduced atopic dermatitis after 3 weeks in all patients.

PUVA-bath photochemotherapy (PUVA-soak therapy) of recalcitrant dermatoses of the palms and soles.

PUVA-bath therapy has proven to avoid many side effects associated with oral 8-methoxypsoralen (8-MOP) treatment. In order to investigate the effectiveness of topical PUVA-bath therapy (PUVA-soak therapy) on chronic palmoplantar dermatoses, 30 patients with plaque-type psoriasis, pustular psoriasis, endogenous eczema, dyshidrotic eczema and hyperkeratotic dermatitis of the palms and soles were treated over 8 weeks with PUVA-soak using 8-MOP. No additional treatment except skin moisturising cream such as unguentum emulsificans aquosum was used during the study period. The single UVA-doses applied ranged from 0.3 to 3.0 J/cm2 (mean single dose of 1.8 J/cm2), with a mean cumulative dose of 48.6 J/cm2 per patient. Altogether 26 of 30 patients responded well within 8 weeks of treatment with 63% of all patients showing a complete remission and 23% showing considerable improvement, as shown by flattening of plaques, decreased scaling and erythema, as well as decreased vesicle and pustule formation. The condition responding best to our therapy was palmoplantar psoriasis followed by atopic eczema. Hyperkeratotic dermatitis displayed the poorest responding rates in this study. Unwanted side effects such as erythema, pain, blistering or patchy hyperpigmentation were not observed in any of the patients. We conclude that PUVA-soak therapy can be highly efficient in the treatment of palmoplantar dermatoses, especially in the management of palmoplantar psoriasis.

Treatment of severe recalcitrant dermatoses of the palms and soles with PUVA-bath versus PUVA-cream therapy.

PUVA-bath therapy developed into a first line topical PUVA therapy, and gel and cream preparations have been described as alternative modes of topical 8-MOP application. Because bath-PUVA can be difficult to manage, topical PUVA therapy using 8-MOP gel or cream preparations may become an important alternative when treating localised skin diseases. However, controlled comparisons of efficacy with this alternative topical PUVA therapy are lacking. We therefore compared the efficacy of PUVA-cream therapy with PUVA-bath therapy in 12 patients with recalcitrant dermatoses of the palms and soles using a left/right trial design. These patients responded well to both treatment modalities, meaning that both could be used successfully to treat recalcitrant dermatoses of the palms and soles.
