Abstract

Lymphatic filariasis presents a spectrum of manifestations with infection-free asymptomatics at one end and elephantiasis at the other. In order to determine if any HLA antigens are associated with the development of elephantiasis, we compared the HLA frequencies in 55 elephantiasis patients with those in 40 controls consisting of individuals older than 45 years of age without any signs of elephantiasis. The only significant difference in class I antigen frequencies was observed for B27, which was present in 11% of the patients and absent in the controls. More differences were observed in HLA class II antigen frequencies. Both DR3 and the 2B3 epitope (on DQ6, DQ8, and DQ9 molecules) were significantly decreased in patients with elephantiasis whereas the DQ5 frequency was significantly higher in patients than in controls. Analysis of specific antibody isotype profiles revealed that DQ5-positive individuals had increased levels of antifilarial IgG3, an isotype known to be involved in tissue damage. These data suggest that HLA class II genes may control the course of Brugian filariasis by influencing the T-cell-dependent antibody repertoire.
