Bleeding risk and reproductive capacity among patients with factor XIII deficiency: a case presentation and review of the literature.
Factor XIII deficiency is an uncommon, inherited bleeding disorder that usually manifests in infancy or early childhood, involving both boys and girls. We present the case of a woman who had experienced two previous intracranial bleeding events, and was treated before and during her current pregnancy with factor XIII concentrate. Her pregnancy was successful, and she experienced an uncomplicated vaginal delivery. To better understand the issues surrounding bleeding, reproductive capacity, and management of factor XIII deficiency during pregnancy, we conducted a systematic literature review using MEDLINE from 1966 to December 1998. We also examined the bibliographic references from all articles, and included all cases, case reports, or case series of patients with factor XIII deficiency. We retrieved data on 117 patients from 37 articles, the majority of which had type II deficiency. Among untreated patients with type II factor XIII deficiency, the literature suggests an elevated mortality rate due to uncontrolled bleeding and intracranial hemorrhage. Because of its high degree of efficacy, the evidence supports the use of life long prophylactic therapy with at least monthly infusions of factor XIII concentrate, including during pregnancy. The opinion that women with type II factor XIII deficiency have inevitable recurrent abortions, or that men are sterile, is not well substantiated. No data were found on whether treatment alters male reproductive capacity. A policy of universal factor XIII replacement, starting in childhood, will likely enable more patients to attain reproductive status. The development of an international data registry would optimally address both bleeding risk and reproductive capacity among patients with factor XIII deficiency.
