Abstract:
Objective:To investigate the clinical characteristics of central nervous system tuberculosis in adults and the possible factors affecting the mortality and disability of the patients.Methods:The clinical data of patients diagnosed as "tuberculous meningitis" "tuberculous meningoencephalitis" "tuberculous cerebrospinal meningitis" or "tuberculous brain ubscess" in Huashan Hospital, Fudan University and Jing′an Branch, Huashan Hospital, Fudan University in Shanghai from January 1, 2010 to December 31, 2017 were collected, and a retrospective cohort was established. The clinical characteristics were analyzed, Medical Research Council (MRC) grade system was used to assess the severity of meningitis, and the modified Rankin Scale was used to assess the impairment of self-care. Survival rate and disability rate of the cohort were analyzed. Binary logistic regression was used for multivariate analysis. Kaplan-Meier survival curve was used for survival analysis.Results:A total of 161 patients with central nervous system tuberculosis were enrolled. Among the 161 patients, 55 cases (34.2%) were confirmed, 72 cases (44.7%) were highly suspected and 34 cases (21.1%) were suspected diagnosis. There were 56 cases (34.8%) with MRC grade Ⅰ, 76 cases (47.2%) with MRC grade Ⅱ and 29 cases (18.0%) patients with MRC grade Ⅲ before treatment. Up to January 1, 2019, ten (6.2%) patients died, 32 (19.9%) patients lost to follow-up, 119 (73.9%) patients survived. The five-year survival rate was 92.83%. There were 72 patients with no impact on life, 34 patients with moderate impact and 13 patients with severe impact. The disability rate was 39.5% (47/119). Binary logistic regression analysis showed that increasing age (odds ratio ( OR)=1.06, 95%confidence interval ( CI) 1.00 to 1.13, P=0.032) and deterioration of MRC grade during anti-tuberculosis treatment ( OR=89.00, 95% CI4.46 to 1 779.00, P=0.003) were independent risk factors for death. When severe disability and death were used as adverse outcomes, logistic regression analysis showed increasing age ( OR=1.07, 95% CI 1.01 to 1.13, P=0.035) and deterioration of MRC grade during anti-tuberculosis treatment ( OR=77.17, 95% CI4.45 to 1 337.00, P=0.003) were still independent risk factors for adverse outcomes. Conclusions:The mortality of central nervous system tuberculosis in adults in this cohort is relatively low, but the disability rate is still high. Increasing age and deterioration of MRC grade during anti-tuberculosis treatment are independent risk factors for death and disability.
