Lipid balance was studied in female patients with late rheumatoid arthritis, their healthy female relatives liable to autoimmune diseases, and healthy women without family history of autoimmune diseases. Previous studies showed that the relatives of patients with rheumatoid arthritis suffered from frequent stubborn common infections, which prompted us to analyze the relationship between lipid metabolism and the infectious syndrome parameters. Blood serum and cells were collected for analysis when females had no clinical symptoms of infections (in all groups) or laboratory signs of inflammatory process (in the relatives and controls). Proatherogenic shifts in serum lipid composition presumably associated with frequent lasting infections were detected in individuals liable to rheumatoid arthritis development. Elevated cholesterol content in mononuclear leukocytes in this group could lead, in turn, to dysfunctions of these cells and augment the defects of anti-infection defense. The parameters of lipid balance in patients with late rheumatoid arthritis were close to the age-specific norm.
