| description | Lichen sclerosus is a skin disorder of unknown prevalence affecting both men and women, and several studies have established HLA associations in women with this disease. Autoimmune disease associations in the form of a personal and/or family history of autoimmune disease have also been shown to be related to lichen sclerosus. In this study, we examined 58 men (mean age 38 years) with lichen sclerosus, 39 of whom had histologically proven disease. HLA tissue typing by phototyping was performed on these patients and contrasted with that of 602 control subjects. There was no difference in antigen frequencies of the HLA class I loci. The patient group was found to have an increased frequency of several HLA antigens of the class II loci: DR11, 13 of 58 (22%) patients vs. 75 of 602 (13%) control subjects (P = 0.05); DR12, five of 58 (9%) patients vs. 16 of 602 (3%) control subjects (P = 0.04); DQ7, 26 of 58 (45%) patients vs. 189 of 602 (31%) control subjects (P = 0.05). There were few autoimmune disease associations: two of 58 (3%) patients had a personal history of a different autoimmune disease, two patients were found to have abnormal thyroid function and six of 58 (10%) had a first-degree relative with an autoimmune disease. There was no difference in the frequency of the autoimmune haplotype HLA A1, B8, DR3/17, DQ2 compared with the control population. HLA DQ7 has now been shown to occur more frequently in both male and female patients with lichen sclerosus, which may reflect the immunopathogenesis of the disease. Autoimmune disease associations, however, are less common in men with lichen sclerosus. |
