| Abstract | Parvovirus B19 infection has been associated with a variety of rheumatic manifestations/diseases, mainly rheumatoid arthritis, vasculitis and systemic lupus erythematosus (SLE). B19 infection may simulate both clinical and laboratory features of SLE, presenting either as a potential first time diagnosis of SLE or as an exacerbation of previously established disease. The similarities in both clinical and serological features of parvovirus infection and SLE at presentation may hinder the differential diagnosis between these two conditions. Hence, parvovirus B19 infection mimicking SLE usually fulfils <4 ACR criteria for SLE, rarely includes cardiac or renal involvement or presents with haemolytic anaemia, and is usually associated with short-lived, low titers of autoantibodies. Rarely, cases of multisystemic involvement solely attributed to a recent parvovirus B19 infection have been reported, rendering early accurate diagnosis of particular importance and justifying the screening for evidence of parvovirus B19 involvement in newly diagnosed cases of SLE, especially the ones with abrupt onset of symptoms along with cases of SLE flares. This review describes basic features of parvovirus B19 structure and pathogenicity and expands on the parvo-associated auto-immune manifestations particularly in relation to SLE-mimicking or SLE-triggering reported cases. The proposed mechanisms for viral-induced pathologic autoimmunity are discussed with emphasis on emerging data regarding the aberrant expression and localization of autoantigens and their potential implication in alternatively activated immunological cascades. |
