Review Case Reports
Transient antiphospholipid antibodies associated with acute infections in children: a report of three cases and a review of the literature.
We describe two previously healthy children who had multiple ecchymoses several days after acute infection. In both cases, the prothrombin time (PT) and the activated partial thromboplastin time (APTT) were prolonged. Further examinations revealed the presence of lupus anticoagulant (LA), phosphatidylserine-dependent antiprothrombin antibodies (aPS/PT), and low serum complement. ⋯ We also describe another asymptomatic case positive for LA and aPS/PT presumably associated with cytomegalovirus infection. The prevalence of transient antiphospholipid antibodies associated with viral infections in children must be much higher than we expected. We have to take it into consideration when we see abnormal coagulation results, but the occurrence of significant bleeding symptoms is rare.

Human metapneumovirus (hMPV) is a recently discovered pathogen in respiratory tract infection. The published literature suggests milder illness severity in hMPV compared with respiratory syncytial virus (RSV) infection. In two consecutive seasons, 637 nasopharyngeal aspirates from pediatric patients were tested by hMPV polymerase chain reaction, and risk factors and clinical and laboratory items were analyzed. ⋯ In 60% of all hMPV infections, the attending physicians prescribed antimicrobial chemotherapy. We conclude that in hospitalized children, hMPV infection is as serious as RSV infection and therefore deserves the same attention. Virologic diagnosis from respiratory secretions is mandatory because clinical, laboratory, and radiological signs cannot sufficiently discriminate between viral and bacterial respiratory tract infection in infants and children.
