[A case of seronegative systemic lupus erythematosus (an immunopathological study)].

A case of systemic lupus erythematosus (SLE) in a 37-year-old female is described which was primarily diagnosed as epilepsy. Immunopathologically, an immunoglobulin in the nuclei of the majority of cells in the skin biopsy and blood cells was found against the background of the lack of SLE manifestations (antinuclear factor in the circulating blood, skin lesions, etc.). Antibodies against the antigen of vascular intima are revealed in the blood by means of the indirect immunofluorescence. The epilepsy diagnosis was established due to the prevalence of the brain vessels affection (frequent loss of consciousness). The progression of the disease with the involvement of joints, heart, lungs and other organs, high indexes of the rheumatoid factor made it necessary to differentiate between rheumatoid arthritis and SLE. The immunopathological examination confirmed the SLE diagnosis. Hemosorption combined with a standard therapy was followed by the decrease of the immunopathological manifestations.
