Abstract

Factor VII (FVII) deficiency is the most common among rare inherited autosomal recessive bleeding disorders. It is a multifaceted disease because of the lack of a direct correlation between plasma levels of coagulation FVII and bleeding manifestations. Clinical phenotypes range from asymptomatic condition—even in homozygous subjects—to severe, life-threatening bleedings (e.g., central nervous system and gastrointestinal bleeding). Menorrhagia is a frequent type of bleeding in FVII deficiency, with a prevalence rate of two in three women aged 10 to 50 years and with a peak prevalence in teenagers. When menorrhagia is observed and once the gynecological causes are excluded, it is important to carry out a hemostasis assessment because, if an anomaly is found, specific treatment can be administered and preventive measures taken. Basic diagnostic work-up includes routine assays, prothrombin level, activated partial thromboplastin time and platelet count, followed by FVII coagulant activity measurement for isolated decreased prothrombin level. To confirm the diagnosis, FVII assay should be repeated at least once. Several treatment options are currently available for FVII deficiency: Recombinant activated Factor VII (rFVIIa), plasma-derived Factor VII, fresh frozen plasma and prothrombin complex concentrates. rFVIIa is the most used replacement therapy. Other medical therapies of menorrhagia includes hemostatic agents and hormonal treatments (combined oral contraceptives, levonorgestrel intrauterine devices), in combination or not with rFVIIa.

We report the case of a fourteen-and-a-half-year-old girl who presented menorrhagia of great abundance at the age of thirteen, the exploration of which revealed a congenital deficit in FVII.
