Fifty unrelated Indian Gurkha of Nepalese origin were studied to analyse the HLA antigen profile and their relation with other populations. Haplotype B35-Cw4 occurred with highest incidence and significant positive linkage disequilibrium in Gurkhas. Haplotype A10-B8 which occurs with the highest frequency in north Indians was also observed to occur with significant positive linkage in Gurkhas. HLA profile of Gurkhas thus may be the result of long-term isolation and genetic drift.

Twenty patients with systemic lupus erythematosus (SLE) and their 51 household contacts were screened for the presence of lymphocytotoxic antibodies. A high prevalence of lymphocytotoxic antibodies (LCTAB) was observed in the patients (80% against T cells and 100% against B cells). The antibodies carried specificity for HLA-B5/35 and HLA-DR2/DR3. A high prevalence of LCTAB was also observed in contacts (55% LCTAB-T cells, 88% LCTAB-B cells) with no difference being seen between consanguineous and non-consanguineous male or female relatives.
