Abstract

BackgroundAmongst Sardinians the human leukocyte antigen HLA DRB1-DQB1 haplotypes *15:02-*06:01, *16:01-*05:02, *14:01-4-*05:03 are protective for multiple sclerosis MS, while *13:03-*03:01, *04:05-*03:01, *03:01-*02:01, *15:01-*06:02 and Mycobacterium avium subspecies paratubercolosis MAP are predisposing factors. We studied the correlation between MAP and HLA.

MethodsFive hundred thirty-one patients were searched for anti-MAP2694 antibodies, DRB1-DQB1 genotyping was performed. The haplotypes were classified as predisposing, neutral or protective.

ResultsAnti-MAP2694 were found in 23 % of subjects carrying one protective HLA versus 32 % without p = 0.04.

ConclusionsWe showed a lower frequency of Abs in patients with protective HLA. These haplotypes could have a protective role for both MS and MAP.
