Outcomes in children with provoked venous thrombosis and antiphospholipid antibodies: findings from the Kids-DOTT trial.

ABSTRACT:

Abstract

Few studies have prospectively evaluated the incidence and outcomes in children with provoked venous thromboembolism (VTE) and transient or persistent antiphospholipid antibodies (aPLs). We compared outcomes of patients aged <21 years with a first-episode acute provoked VTE and positive aPL at diagnosis, enrolled in the Multicenter Evaluation of the Duration of Therapy for Thrombosis in Children trial. aPLs were tested at enrollment and, when positive, repeated at 6 weeks after VTE diagnosis. Subsequent testing was performed at the discretion of the treating hematologist. Of 524 patients, 116 (22%) had positive aPLs at enrollment. At follow-up, 70 (60%) had transient (n = 66) or low-titer aPLs (n = 4), 11 (10%) had persistent aPLs meeting the criteria for antiphospholipid
