The PSORS1 locus in the major histocompatibility complex region is the major genetic determinant for psoriasis vulgaris. Within the PSORS1 region reside at least three potential candidate genes for psoriasis susceptibility. Specific allelic variants of the genes HLA-Cw*6, HCR*WWCC, and CDSN*5 are strongly associated with psoriasis vulgaris and are in strong(More)
Pustulosis palmoplantaris (PPP) is a common chronic skin disease, which is very resistant to treatment. It is not known why the lesions are located in the palms and soles. There are few studies of the disease and in particular studies of the histology. Fifty-nine patients with PPP answered a questionnaire concerning their medical history and 39 of them were(More)
The serum levels of zinc and retinol-binding protein (RBP) have been determined in 173 patients with acne and compared with those of a control group. The RBP is a specific transport protein and its level in plasma reflects the amount of vitamin A available to the tissues. Patients with severe acne were found to have lower levels of RBP than either patients(More)
OBJECTIVES To find out whether patients with psoriatic arthritis (PsoA) have an increased prevalence of antibodies to gliadin (AGA) and of coeliac disease. METHODS One hundred and fourteen PsoA patients with skin disease of 20+/-13 yr and joint disease of 11+/-10 yr duration answered a questionnaire concerning their medical history and underwent clinical(More)
Pro-vitamin A(beta-carotene) and the predominant forms of vitamin A in human skin (retinol and dehydroretinol) were analyzed in hydrolyzed specimens from 4 cadavers and 22 healthy subjects. Beta-carotene was identified in extracts of epidermis by its specific absorption spectrum. Vitamin A was determined by high-pressure liquid chromatography. The(More)
In a previous screening study, 16% of patients with psoriasis had IgA and/or IgG antibodies to gliadin (AGA). The aim of the present study was to evaluate the effect of a gluten-free diet (GFD) in 33 AGA-positive and six AGA-negative psoriasis patients. Of the 33 AGA-positive patients, two had IgA antibodies to endomysium (EmA) and 15 an increased number of(More)
Palmoplantar pustulosis is characterized by pustule formation in the acrosyringium. Nearly 50% of palmoplantar pustulosis sera produce immunofluorescence of the palmar papillary endothelium from healthy subjects, but also of the endothelium of normal parathyroid gland. With a case-control design the levels of calcium and parathyroid hormone in serum were(More)
Concentrations of selenium in whole blood and plasma in 113 patients with moderate to severe psoriasis were compared with those in 104 healthy reference subjects. Most of the patients (85%) had had their psoriasis for at least 10 years and all had previously been treated with PUVA baths. Selenium concentrations both in whole blood and plasma were decreased(More)
Elevated serum triglyceride and low serum HDL cholesterol levels have been reported to be risk factors for occlusive vascular disease. In 20 middle-aged men with psoriasis the serum lipoprotein pattern was compared with that in a group of healthy middle-aged men. In thirteen of the 20 patients the psoriasis was mild to moderate and in seven patients it was(More)
