MARABI, Phidelis M. et al. Association between coagulation indicators and menorrhagia among women in Kenya. Afr. J. Lab. Med. [online]. 2024, vol.13, n.1, pp.1-8. ISSN 2225-2010.  https://doi.org/10.4102/ajlm.v13i1.2438.

BACKGROUND: Despite the significant burden of menorrhagia (bleeding > 80 mL every menstrual cycle) among women in Western Kenya, it remains unknown whether coagulation disorders are an important underlying cause of this condition in the region OBJECTIVE: This study assessed differences in coagulation profiles, associations between menorrhagia and coagulation profiles and compared morphological features of platelets among women attending Bungoma County Referral Hospital in Kenya METHODS: A comparative cross-sectional study of women with and without menorrhagia, aged 18-45 years, was performed between December 2022 and September 2023. Sociodemographic factors, prothrombin time (PT), activated partial thromboplastin time, thrombin time, fibrinogen, international normalised ratio (INR), and platelet count were compared between groups, and associations with menorrhagia were assessed. Prothrombin time and INR levels above normal references were deemed increased RESULTS: A total of 428 (214 per group) women were included. Family history of bleeding disorders (p < 0.0001) was more frequent in menorrhagic than in non-menorrhagic women. Additionally, menorrhagic women had high PT (p < 0.0001) and high INR (p < 0.0001) levels. Menorrhagia was significantly associated with an increased PT (odds ratio = 2.129, 95% confidence interval = 1.658-2.734; p < 0.0001) and increased INR (odds ratio = 7.479, 95% confidence interval = 3.094-18.080; p < 0.0001 CONCLUSION: In this population in Western Kenya, menorrhagia was associated with a family history of bleeding disorders, increased PT, and increased INR. Routine assessment of the coagulation profile and family history of bleeding disorders is crucial for diagnosing and managing menorrhagia WHAT THIS STUDY ADDS: Our findings suggest that menorrhagic and non-menorrhagic women differ in terms of PT and INR, which may be predictive of menorrhagia.
