摘要
Background: The prevalence of antiphospholipid antibodies (aPLs) during acute Epstein-Barr virus (EBV) infection may be as high as 30-60%. The role of these autoantibodies in the development of antiphospholipid syndrome (APS) is not clear. Objective: To investigate the prevalence, persistence and clinical significance of aPLs in a series of patients diagnosed with acute EBV infection. Study design: A cohort of 94 patients aged 15 or older, recently diagnosed with acute EBV was retrieved. Serum samples obtained during diagnosis were tested for the presence of aPLs and anti-beta(2)GP antibodies. Patients with positive sera for aPLs were assessed for the persistence of aPLs and the development of APS. Results: The prevalence of aPLs among 94 patients with acute EBV was 37.2%. Five of 27 available serum samples were also positive for anti-beta(2) glycoprotein (anti-beta(2)GP) antibodies. Repeat testing for aPLs after a median of 21 months post acute infection (range 13-50 months) was performed in 17 of the 35 patients with positive aPL test. All 17 patients were found negative for aPL-IgG antibodies. Two of them had positive aPL-IgM antibodies and positive anti-beta(2)GP antibodies. None of the patients who had positive aPLs experienced any manifestations of APS. Conclusion: The disappearance of aPLs in the majority of the patients after acute EBV infection, along with the absence of consistent clinical findings, suggests that the detection of aPLs during acute EBV is not associated with the development APS over time.
