A 4-year-old boy was admitted with left hemiplegia. Thrombophilia marker examination resulted with factor V Leiden mutation heterozygosity, a deficiency of antithrombin III and a high level of factor VIII. Cranial computed tomography scan revealed an ischemic infarct in the region of right anterior cerebral artery. In the literature, combinations of multiple thrombophilia risk factors that trigger cerebral ischemic stroke in children have been emphasized. To our knowledge, this is the first child with these combinations of thrombophilia risk factors and ischemic stroke to be reported in the literature.

The objective of this study is to report a new manifestation of acute stroke following antifibrinolytic agent administration in young women carrying heterozygosity for methylene-tetrahydrofolate reductase (MTHFR) C677T. The study included two young women who developed an acute ischaemic stroke following three days of tranexamic acid administration for bleeding gynaecological disorders. Case 1, a 44-year-old woman, presented left hemiplegia, mild dysarthria and anosognosia. Brain magnetic resonance imaging showed right ischaemic fronto-temporal lesion due to subocclusion of the right middle cerebral artery. Case 2, a 49-year-old woman, developed aphasia and right hemiplegia. Neuroimaging showed left capsular and periventricular infarcts due to near occlusion of the left internal carotid artery. Thrombophilia screening, coagulation parameters, homocysteine testing, 12-lead electrocardiography, and transthoracic and transoesophageal echocardiography were unremarkable. Genetic assay showed that both patients carried heterozygosity for MTHFR C677T, in which cytosine (C) is replaced by thymidine (T) at base position 677. To our knowledge, this is the first report describing the association between genetic factors and the onset of stroke following antifibrinolytic drugs intake. These data suggest a synergic effect of plasminogen activator inhibitor and heterozygosity for MTHFR C677T on the pathogenetic mechanisms leading to ischaemic stroke in young people.

Background. In the United States, ischemic stroke in HIV-infected patients has increased by 60%. However, unexpected cardiovascular events in relatively young patients have been observed. Clinical Vignette. A 31-year-old male who presented with a 5-hour history of sudden onset slurred speech and left hemiplegia. He has medical history of HIV infection for 2 years taking ARTs. On exam, a significant left hemiparesis was noticed. Brain MRI showed right anterior corona radiata and basal ganglia acute infarction. Discussion. Several mechanisms have been proposed for the relationship between HIV infection and cardiovascular risk. (i) HIV-associated dyslipidemia: HIV-infected patients tend to develop decrease in HDL-c and LDL-c levels. ART was associated with an increase in LDL-c but little change in HDL-c. (ii) Endothelial dysfunction: certain antiretroviral agents may independently contribute to endothelial damage. (iii) Hypertension: systolic blood pressure is higher in those using ART for greater than five years. (iv) Insulin resistance and diabetes have been noticed with ART. (v) Chronic inflammation. (vi) Hypercoagulability: decrease in proteins C and S was associated with HIV infection. Conclusion. Poorly controlled HIV infection and/or the introduction of ATR might be risk factors for cardiovascular events. More studies needed to address this medical dilemma.
