The aim of this study was to investigate the effect of iontophoresis combined with local psoralen plus ultraviolet A (PUVA) therapy in chronic foot eczema. A randomized, observer-blinded, multi-centre study was conducted in 48 patients with chronic moderate-to-severe foot eczema randomized to one of 3 groups: In the iontophoresis group local bath-PUVA was preceded by iontophoresis. In the PUVA ...

AIM Amyloidosis is a common disorder in adults. Secondary amyloidosis in patients with mycosis fungoides (MF) after photochemotherapy with 8-methoxypsoralen followed by ultraviolet A (PUVA) treatment has not been reported. Our aim is to describe the clinical and histological features of PUVA phototherapy-induced secondary amyloidosis. MATERIALS AND METHODS Sixty-one patients with MF treated w...

BACKGROUND AND OBJECTIVES A combination of 8-methoxypsoralen and ultraviolet-A radiation (PUVA) is used for the treatment of T cell-mediated disorders, including chronic graft-versus-host disease. The mechanisms of action of this therapy, referred to as extracorporeal phototherapy, have not been fully elucidated. PUVA is known to induce apoptosis in T lymphocytes collected by apheresis, however...

The association between psoriasis vulgaris and bullous pemphigoid is due to the still unclear autoimmune process. The common disease site is the dermo-epidermal junction or basal membrane zone (BMZ), with specific alterations for both diseases. Photochemotherapy (PUVA) is one of the therapeutic modalities for psoriasis and can trigger production of autoantibodies against antigens in the BMZ in ...

AIM To assess the efficacy of betamethasone dipropionate 0.05% cream plus ultraviolet B (UVB) radiation with and without additional penicillin therapy in the treatment of guttate psoriasis, and to compare the efficacies of oral psoralen plus ultraviolet A (PUVA) therapy and systemic retinoids therapy for treatment of generalized psoriasis. METHODS Sixty patients with guttate (n = 20) and gene...

BACKGROUND PUVA photochemotherapy is indicated to treat mycosis fungoides, either as monotherapy in the earlier stages of the disease or in combination with other drugs in more advanced stages of evolution. OBJECTIVES – To evaluate PUVA photochemotherapy response in patients with mycosis fungoides. METHODS From January 1996 to November 2003, 17 patients with a diagnosis of mycosis fungoides wer...

To the Editor: We report the case of an 80-yearold man with localized scleroderma, treated successfully with PUVA therapy. The patient came to our office with progressive hardening of his abdominal skin. Clinical examination (Fig. 1) showed a large (25 cm in diameter) slightly erythematous plaque that could not be pinched and made it difficult for the patient to bend down. The lesion margins we...

Ultrastructural studies were conducted in order to determine morphologic and functional differences in melanocytes and melanosomes in PUVA lentigines and solar lentigines, and light-protected buttock skin. Compared to melanocytes in solar lentigines from 7 subjects and light-protected buttock skin from 5 subjects (none of these subjects had received UV radiation therapy), melanocytes in PUVA le...

Background: Chronic graft versus host disease (ch.GVHD) is the most frequent late complication after allogenic stem-cell transplantation. Systemic immunosuppressive agents are usually required to control the disease. Psoralen plus UVA (PUVA) has been used for the treatment of ch.GVHD with variable beneficial effects. The objective of this study was to assess the efficacy and safety of a r...
