Summary The role of HLA antigens, and HLA-DR2 in particular, in the determination of mean sleep onset latencies (MSOLs) in multiple sclerosis (MS) was studied. It has been suggested that this antigen may play a part in the reduction of MSOLs, since nearly 100% of patients suffering from narcolepsy are DR2-positive. A multiple sleep latency test was performed in 37 patients suffering from MS without spontaneous complaints of sleep disturbances and who were typed for HLA-A, B, C, DR and DQ. The MSOL was reduced in a total of 21 patients, in only 7 of 15 DR2-positive patients and in 12 of 21 DQw1-positive patients. However, it was reduced in 13 of 16 B8- or B14-positive patients. In contrast with this, in the absence of an early sleep onset (MSOL 〉30 min), no HLA antigens were found to be over-represented when considered individually; only those patients positive for a group of cross-reacting HLA antigens (B5, B15, B18, B21 or B35) had an MSOL greater than 30min. These results suggest that the genes which code for the DR2 or DQw1 antigens, which are present in nearly 100% of narcoleptics, are not solely responsible for the appearance of an early sleep onset in MS.
