New immunological data (Brit. med. J., 1976, 1, 183-186) lead us to a fundamental reconsideration of the immunopathological concept of multiple sclerosis (MS). The increased incidence of the infection rate during childhood, the low humoral and cell-mediated immune responses towards many bacterial and viral antigens and the presence of these specific immune deficiencies in a group of doubtful MS cases being at the first bout of the disease, led us to consider MS as a multi-specific immune deficiency disease, possibly having its origin in the genes controlling the immune response to these specific antigens. We now consider MS as being the end result of multi-specific immune deficiencies, which would explain the increased incidence of tonsillectomies, appendicectomies and repeated infections during childhood and the presence of numerous small inflammatory and pyrexic processes, often benign, but susceptible to cause in the target tissue--the central nervous tissue--the demyelinization process which could well be not specific at all. This new optic opens the way to the use of different immunotherapy regimens including transfer factor or whole lymphokines, and stimulation of the immune response with immunological adjuvants rather than immunosuppressive agents used during recent years (like steroids, ACTH) which have an antiinflammatory as well as an immunosuppressive function.
