To elucidate the molecular action of 8-methoxypsoralen plus UVA (PUVA), a standard dermatological therapy, we used K5.hTGF-beta1 transgenic mice exhibiting a skin phenotype and cytokine abnormalities with strong similarities to human psoriasis. We observed that impaired function of CD4+CD25+ regulatory T cells (Tregs) and increased cytokine levels of the IL-23/Th17 pathway were responsible for ...

Case Report A 53-year-old male anaesthetist with a widespread, histologically proven psoriasis vulgaris was treated with oral photochemotherapy (PUVA) after failure of multiple intensive topical treatments and poor response to UVA-UVB phototherapy. PUVA was begun according to our standard protocol: 2 h after oral administration of 5-MOP 100 mg (Geralen , 1.2 mg/kg body weight), the patient was ...

Background and aim: Psoriasis is one of the most common inflammatory skin disorders with a genetic background. Several treatment modalities have been used, including systemic and bath PUVA. The aim of this study was to evaluate the efficacy of systemic and bath PUVA in the treatment of psoriasis in Razi Hospital.Materials and methods: This retrospective database study was done in Razi Hospital ...

BACKGROUND Bath-PUVA-photochemotherapy has become a useful alternative to oral PUVA therapy due to a number of advantages over systemic PUVA, for example, no ophthalmologic risk and nausea, and a lower cumulative UVA doses. However, its major disadvantage is the logistical requirement for bath tubs in practice and some patients feel uncomfortable to share the same bath with others. Topical psor...

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...

Antigen Ki-67 is a non-histone nuclear protein, closely connected with cell proliferation. Determining Ki-67 allows for a quick and reliable evaluation of the growth fraction of the studied cell population. It serves as a marker of proliferative activity in neoplasms and other diseases with excessive cell proliferation such as psoriasis. Evaluation of Ki-67 expression in epidermal cells was per...

Cutaneous T-cell lymphoma (CTCL) constitutes a malignant proliferative disease involving mostly CD4(+) T cells arising in the skin. Because of the lack of curative treatment options, interferons (IFN) have been introduced into the therapy of CTCL. Although effective even in advanced disease, response rates were about 50% and the duration of response was short. To improve the results of interfer...
