Abstract

In the literature, there are case reports suggesting that Borrelia burgdorferi infection may induce autoimmune diseases dependent on antinuclear antibodies (ANA). The present study was undertaken in order to verify this possibility in a prospective manner. The study group comprised 78 consecutive patients (51 women and 27 men, median age 41.5 years) referred to our Department for the serologic diagnosis of Borrelia infection. The patients' sera were tested for Borrelia-specific IgM and IgG (Recombinant Antigen Enzyme Immunoassays, Biomedica). Antibodies against Borrelia were detected in 31 (39.7 %) persons. 15 persons (19.2 %) had positive IgM, another 15 (19.2 %)--positive IgG, and 1 person (3.2 %)--both IgM and IgG. Frequent positivity of IgM antibodies suggests that persons in the early phase of infection prevailed in the group. Tests for anti-dsDNA, anti-RNP, anti-Sm antibodies, and a screening test for systemic rheumatic diseases (ANA Rheuma Screen) were carried out using Varelisa Enzyme Immunoassays (Pharmacia and Upjohn). The spectrum of autoimmune diseases covered by these tests included SLE, MCTD, Sjogren's syndrome, scleroderma, polymyositis, and dermatomyositis. ANA were detected in 15 persons (19.2 %): anti-dsDNA in...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
