The occurrence of bullous pemphigoid (BP) in patients with psoriasis has occasionally been reported. Most previously reported cases attributed the occurrence of BP in psoriasis to photochemotherapy, such as PUVA, UVA and UVB (1–4). We describe here a patient who initially had psoriasis vulgaris and subsequently developed BP after treatment with UVA for psoriasis. Histopathologic, direct immunof...
A 41-year-old man presented with a ten-year history of recurrent erythema and swelling of skin that occurred following sun exposure even as little as ten minutes. The lesion affected only on the sun exposed area. A phototesting was carried out and revealed that urticaria was induced following ultraviolet A (UVA) and visible light exposure. Solar urticaria (SU) from UVA and visible light was dia...
Photochemotherapy, the combination of a photosensitiser and ultraviolet (UV) or visible light, is an effective treatment for skin conditions including cancer. The high mutagenicity and non-selectivity of photochemotherapy regimes warrants the development of alternative approaches. We demonstrate that the thiopyrimidine nucleosides 5-bromo-4-thiodeoxyuridine (SBrdU) and 5-iodo-4-thiodeoxyuridine...
Three age- and sex-matched groups of 30 patients with chronic plaque psoriasis were treated by photochemotherapy (PUVA). Groups I and II received routine maintenance PUVA therapy at different intervals and Group III had no maintenance treatment. The remission time after the clearance treatment with PUVA is compared with the total cumulative dose of long wave ultraviolet light (UVA). A lower mea...
Psoriasis is a chronic, inflammatory scaling disorder of the skin. Different patterns of psoriasis exist including plaque type, erythrodemic, pustular, palmoplantar and guttate. The most commonly involved sites are the elbows, knees, lumbosacral area and scalp. PUVA (Psoriasis Plus UVA) therapy [administration of oral psoralen followed by exposure to UVA (320 to 440 nm)] is widely used to treat...
Photochemotherapy-in which a photosensitizing drug is combined with ultraviolet or visible radiation-has proven therapeutic effectiveness. Existing approaches have drawbacks, however, and there is a clinical need to develop alternatives offering improved target cell selectivity. DNA substitution by 4-thiothymidine (S(4)TdR) sensitizes cells to killing by ultraviolet A (UVA) radiation. Here, we ...
Background: Treatment of early-stage mycosis fungoides (MF) consists of topical steroids, phototherapy (UVB), photochemotherapy (psoralen plus UVA [PUVA]), topical nitrogen mustard, or total skin electronbeam irradiation. It has been reported that the same effective UVB dose is safer than PUVA regarding carcinogenicity and produces fewer side effects. Narrowband UVB (311 nm) results in less irr...
BACKGROUND Localized scleroderma (LS) comprises a spectrum of sclerotic autoimmune diseases primarily affecting the dermis. Various treatment modalities have been recommended for the management of LS, but only a few studies exist regarding the efficacy of bath PUVA photochemotherapy in the treatment of LS. OBJECTIVES To evaluate the efficacy of bath PUVA photochemotherapy in the management of...
BACKGROUND Broad-band UVA, long-wave UVA1 and PUVA treatment have been described as an alternative/adjunct therapeutic option in a number of inflammatory and malignant skin diseases. Nevertheless, controlled studies investigating the efficacy of UVA irradiation in connective tissue diseases and related disorders are rare. METHODS Searching the PubMed database the current article systematicall...
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...
