Safety evaluation and expanded disability status scale (EDSS) rating were performed every 3 months and in the 3rd year every 6 months and when clinical relapses occurred. Relapses were defined according to Poser criteria and annual relapse rates were calculated for the 3 year study duration and a 2 year prestudy period. As two patients reported generalised tender swelling of lymph nodes spontaneously in temporal relation to the beginning of GA injections special attention was paid to the … ER -
