J Obstet Gynaecol Res 2021 Jun 24. Epub 2021 Jun 24.

The Study Group for Hereditary Thrombophilia, Research on Blood Coagulation Abnormalities, Research Program on Rare and Intractable Diseases, The Ministry of Health, Labour and Welfare Science Research Grants, Tokyo, Japan.

Hereditary thrombophilia is a condition in which individuals are susceptible to the formation of thrombi due to a hereditary deficiency in anticoagulant factors, antithrombin (AT), protein C (PC), or protein S (PS). Many Japanese thrombophilia patients have PS deficiency, especially PS p.K196E (also called as PS Tokushima), which is exclusive to the Japanese population, and thrombosis sometimes occurs during pregnancy.

A study of hyperhomocysteinemia in cerebral venous sinus thrombosis.

Indian J Med Res 2020 Dec;152(6):584-594

Department of Neurology, Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India.

Background & Objectives: Vegetarianism may result in low vitamin B12 and acquired hyperhomocysteinemia leading to thrombotic conditions such as cerebral venous sinus thrombosis (CVST). The clinico-radiological presentation and outcome of patients with hyperhomocysteinemia may be different from those without, but there is a paucity of information. This study was undertaken to find out the relationship of homocysteine (Hcy) with vitamin B12, folic acid and methyltetrahydrofolate reductase (MTHFR) mutation in the patients with CVST, and compare clinico-radiological severity and outcome of patients with and without hyperhomocysteinemia.
