Moderately elevated plasma total homocyst(e)ine (tHcy) levels have been linked with cardiovascular disease. However, the findings of previous studies regarding the relationship between tHcy levels and subtypes of cerebral infarction (CI) have been conflicting. The aim of the present study was to examine this issue in a community-based case-control study performed in Hisayama Town in Japan. Fasting tHcy levels were compared among 75 CI cases, of which 43 were lacunar (LI), 24 atherothrombotic (ATI) and 8 cardioembolic infarctions (CEI), and 248 age- and sex-matched healthy controls. The mean tHcy concentrations were higher in CI than in controls (13.0 vs. 11.8 micromol/l; p = 0.018). LI and CEI also had significantly higher tHcy levels than did the corresponding controls (12.3 vs. 11.3 micromol/l for LI; p = 0.037 and 16.3 vs. 12.7 micromol/l for CEI; p = 0.036). The same tendency was also observed for ATI, but the difference was only marginally significant probably due to the small number of the cases (13.4 vs. 11.9 micromol/l; p = 0.087). After adjustment for age, sex, hypertension, serum creatinine, total protein, folate and vitamin B(12) levels, the risk of LI was not significant in the second tertile of the tHcy distribution, but significantly increased in the third compared with the first tertile (adjusted odds ratio, AOR, 3.4; 95% confidence limits, CL, 1.3-8.9; p = 0.015), while the risk of ATI was significant even in the second tertile (AOR, 5.0; 95% CL, 1.0-23.7; p = 0.042) and higher in the third tertile (AOR, 7.5; 95% CL, 1.5-38.3; p = 0.015). However, the odds ratios for CEI could not be estimated, as there was no case of CEI in the first tertile. These findings suggest that elevated tHcy is an independent risk factor for all subtypes of CI, but that its impact is higher in ATI and probably in CEI than in LI.

Background and Purpose- Cerebral infarctions complicate a variable proportion of tuberculous meningitis (TBM) cases and adversely affect outcomes. The objective of this study was to evaluate the predictors of cerebral infarcts in patients with TBM and to assess their impact on mortality. Methods- The study was based on a retrospective chart review of all patients with TBM admitted to a tertiary care hospital between 2002 and 2013. Data were collected on basic demographics, conventional vascular risk factors, radiological findings, severity of TBM, and neurological outcomes. Data were analyzed using SPSS version 19.0. Binary logistic regression was done to determine the factors predictive of cerebral infarcts and of mortality in patients with TBM. Results- A total of 559 patients were admitted with TBM during the study period. Mean age was 41.9 years (SD, 17.7 years), and 47% were women. A quarter of the patients had stage III disease. One hundred forty-four (25.8%) patients had cerebral infarcts on brain imaging of which 3 quarters were acute or subacute. Those with cerebral infarcts were more likely to be >40 years of age (adjusted odds ratio [AOR], 1.7; 95% CI, 1.1-2.7) and to have hypertension (AOR, 1.8; 95% CI, 1.1-2.8), dyslipidemia (AOR, 9.7; 95% CI, 3.8-24.8), and diabetes mellitus (AOR, 2.2; 95% CI, 1.3-3.6). Presence of cerebral infarction was an independent predictor of mortality among patients with TBM (AOR, 2.1; 95% CI, 1.22-3.5). Conclusions- Cerebral infarcts complicate a substantial proportion of TBM cases. Conventional vascular risk factors are the most important predictors of infarction, and future efforts need to focus on these high-risk patients with TBM to reduce morbidity and mortality.
