Chronic graft versus host disease (GVHD) remains the most common late complication of allogenic stem cell transplantation and the most frequent cause of morbidity and mortality in these patients. To control this condition, immunosuppressive drugs are usually administered at a high dose and for a long time, which may result in several side effects. 5 patients with clinically and histopathologica...

BACKGROUND PUVA treatment is photochemotherapy for psoriasis that combines psoralen with UVA radiation. Although PUVA is a very effective treatment option for psoriasis, there is an absence of patient resources explaining and demonstrating the process of PUVA. Studies have shown that patients who viewed videos explaining the treatment procedures for various medical conditions had a greater unde...

We systematically reviewed the evidence concerning the ability of five systemic treatments to induce remission in patients with severe psoriasis: ultraviolet B (UVB), photochemotherapy (PUVA), methotrexate (MTX), retinoids (RET) and cyclosporin A (CYA). An elaborate literature search was performed, the validity of studies was assessed, and data were analysed. In total, 89, 193, 101, 155 and 127...

Sir, The development of melanocytic lesions following treatment with psoralen and ultraviolet A (PUVA therapy) is well documented. The first case of lentigines induced by cosmetic UVA tanning was reported in the 1980s (1), and another three cases have been published since then (2 – 5). We report the case of a woman with systemic lupus erythematosus (SLE) who developed generalized persistent mel...

Phototherapy is a widely used treatment for multiple skin diseases, but particularly in psoriasis [1,2]. Many modalities for phototherapy have been used and investigated in the treatment of psoriasis patients: UVA with psoralens (so called local or systemic PUVA), broadband UVB (BB-UVB) and narrowband UVB (NB-UVB). These UV-treatments can be given in different schemes daily, twice or thrice wee...

Psoriasis is characterized by alterations in both the epidermis and dermis of the skin. Epidermal keratinocytes display marked proliferative activation and differentiate along an "alternate" or "regenerative" pathway, while the dermis becomes infiltrated with leukocytes, particularly interleukin 2 (IL-2) receptor-bearing "activated" T cells. Psoralens, administered by the oral route, have thera...

OBJECTIVE To perform a cost-effectiveness analysis, by using a decision tree model, comparing methotrexate with PUVA therapy for moderate to severe chronic plaque psoriasis in the sanitary area of Badajoz (south-western Spain) over a one-year period. MATERIAL AND METHODS The following variables and data sources were included: efficacy (a 50 % reduction in the PASI) and safety (adverse reactio...
