An immunological study of Lyme disease.

Abstract

84 patients in the second or third stages of serologically diagnosed Lyme disease suffering from different forms of central as well as peripheral nervous system involvement were tested for the participation of autoimmune mechanisms. Cell hypersensitivity to the encephalitogenic basic protein and to antigens from peripheral myelin was evaluated on an Opton cytopherometer according to the effect of the macrophage slowing factor--liberated during short-term incubation of sensibilized lymphocytes by the respective antigen--on the mobility of tannin-treated sheep red blood cells in an electric field. Judged by the presence of autoimmune reactions. Lyme disease has come to occupy a prominent position compared with previously examined other types of neuroinfections. An explanation can be sought in disordered immunoregulating mechanisms, even though the changes in total and active T lymphocytes were not statistically significant. Data on immunological changes are relevant for the indication of immunomodulating therapy as a suitable complement to antibiotic treatment.
