Nine patients with multiple sclerosis, four with relapsing‐remitting disease, and five with chronic progressive disease, together with eight healthy control, were followed for nearly a year with monthly clinical and laboratory examinations. Alpha‐ and gamma‐interferon was induced in lymphocytes with different viruses and PHA, no differences were found between healthy controls and multiple sclerosis patients. The alpha‐ and gamma‐interferon induced enzyme 2′‐5′ oligo A synthetase in lymphocytes was found to have a tendency to be lower in multiple sclerosis patients than in healthy controls. When medians of ratios of helper/suppressor blood lymphocytes in multiple sclerosis patients were compared with healthy controls, the same results were found, although higher values of ratios were found among the patients and the highest value was found in a patient with chronic progressive disease. No correlation to disease activity could be found in interferon inductions, 2′‐5′ oligo A synthetase concentrations and ratios of OKT 4 /OKT 8 . In particular no change in ratio was found in relation to five exacerbations taking place in the four multiple sclerosis patients with acute relapses.
