Abstract

We sought to evaluate a possible link between parvovirus B19 infection and the clinical and laboratory expression of systemic lupus erythematosus (SLE). SLE patients were examined to evaluate their clinical status and disease activity. A complete Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score was obtained for each patient. In addition, we determined the level of systemic involvement throughout the course of the disease. Blood levels of IgM and IgG antibodies to parvovirus B19, levels of anti-dsDNA, C3, and C4 were measured. A PCR real-time assay was used to determine the presence of parvovirus B19 genetic material. The viral genome was found in sera of 2 of 51(3.9%) patients with SLE. There was no correlation between viral serology and the clinical and serological parameters of the disease. More SLE patients with secondary antiphospholipid syndrome (APS) had IgG and IgM antibodies to the virus (p < 0.029 and p < 0.018, respectively). These patients also had a higher titer of IgG antibodies to parvovirus B19 compared to SLE patients without APS. In this group of SLE patients, no association was found between parvovirus infection and the presence or activity of SLE. The results of the study suggest an association between parvovirus infection and antibody production directed against phospholipids.[MediaObject not available: see fulltext.].
