HLA-antigens and the prognosis of multiple sclerosis.

The histocompatibility pattern of 160 patients with multiple sclerosis (MS) living in the epidemiological area of Southern Lower Saxony was determined and compared to a control population. The only significant difference was the more frequent occurrence of DW2 in the patient group (44% vs. 21%). Taking a progression index (grade of disability divided by the duration of the disease) as a measure for prognosis no difference could be found between the DW2 positive and the DW2 negative patients. The reason why we could not confirm the worse prognosis for DW2 positive patients found by Jersild et al. (1973) and Raun et al. (1980) remains to be investigated.
