Familial alopecia areata--genetic susceptibility or coincidence?

Three generations of a not consanguineous Italian family and 40 subjects suffering from alopecia areata (AA) and residing in Northern Italy were studied. There were 321 healthy control subjects of both sexes. Six family members from three generations were affected with alopecia universalis. The subjects were HLA-phenotyped using different HLA-A, B and C antigen specificities. No significant association was found between HLA-A, B and C antigens and AA patients at the population level. Segregation analysis showed that affected members shared a common haplotype, HLA-Aw32, B18,-.

Mycosis fungoides. Peripheral T cell subsets defined by specific monoclonal antibodies.

Peripheral blood lymphocytes from 16 mycosis fungoides (MF) patients were studied using OKT series monoclonal antihuman T cell antibodies. The percentage of OKT3+ cells was in normal range for all MF patients compared with controls; the percentage of OKT4+ cells was significantly increased (p less than 0.002) in MF patients versus controls; the percentage of OKT8+ and OKT11+ cells in the MF group did not differ from controls. The OKT4+ cell expansion was apparently not dependent from the clinical stage of disease. These findings suggest that in MF patients there is a circulating OKT4+ cell expansion and, indirectly, that MF could be regarded as a helper T cell neoplasm.
