Background and Objectives: Tuberculosis (TB) is an important cause of childhood morbidity and mortality with different clinical presentations and outcomes as compared to TB in adults. The present study was designed to compare these differences and to determine if childhood TB was an important predictor of adverse outcome following treatment under the Revised National Tuberculosis Control Program (RNTCP). Materials and Methods: Retrospective record based study of cases registered between January 2008 and December 2011, at the Amdanga TB Unit (TU), West Bengal. Results: Of the total 1,508 cases notified, 3.4% were childhood TB. Differences with adult TB were noted in the number of cases categorized as cat II and III in children (P = 0.012 and 0.000, respectively). New smear positive pulmonary TB was significantly lower (21.6%, P = 0.000), while new extra-pulmonary TB (39.2%, P = 0.000) was significantly higher in children. Smear negative cases comprised 7.8 and 11.4% of the childhood and adult cases of TB, respectively. Retreatment cases were significantly higher in adults (P = 0.012). Among the registered new smear positive cases, the differences in favourable and adverse outcomes did not have a significant statistical difference (P = .100) . Childhood TB was not a significant risk factor for adverse outcome following treatment (adjusted odds ratio [AOR] = 0.80, 95% confidence interval [CI] = 0.28-2.32). Conclusions: The registration of childhood TB under the RNTCP in the TU was low. There were differences in the clinical presentation and treatment outcomes of TB among children and adults. Childhood TB was not a significant predictor of adverse treatment following treatment. [ABSTRACT FROM AUTHOR]

Introduction: An increased notification rate of tuberculosis (TB) in men is seen in the SAARC region. In India, the Revised National Tuberculosis Control Programme (RNTCP) detects nearly three times more male than female TB patients. Gender differences have also been reported in the clinical forms of tuberculous disease and in treatment adherence and cure rates in patients undergoing treatment for tuberculosis. The present study was undertaken to find out the sex differences in the notification rates and treatment outcomes of TB patients registered under the RNTCP in a rural tuberculosis unit (TU) in West Bengal. Materials and Methods: A retrospective record-based study was carried out among a total of 3605 cases registered under the RNTCP between January 1999 and June 2005. Notification rates of TB, clinical forms of TB and disease treatment outcomes recorded in the registers were analyzed based on genders. Outcomes were defined in accordance with the standard RNTCP definitions. The Z-test for proportion (for comparing differences in proportions), Student t-test (for comparing mean), and ?2 test (to see association) were performed for statistical analysis. Results: Among the total of 3605 patients, 2498 (69.3%) were male and 1107 (30.7%) were female with a male female ratio of 2.25:1. In patients less than 20 years of age, the notification rates among males and females were similar. In the other age groups, males were more likely to be notified compared to females and the difference was statistically significant. While new smear positive and retreatment cases were significantly more than in males, among females, new smear negative and new extrapulmonary cases were significantly higher. Among the new smear positive patients 89.4% of females were cured compared to 85.8% of males which was again significant statistically (Z=1.70, P<0.05). Male patients outnumbered females in all the unfavorable outcomes like death, failure, and default although none of the differences were statistically significant (P>0.05). Conclusion: The present study demonstrates a gender difference in the notification rates, clinical presentations and treatment outcomes of patients with tuberculosis. Integrated research is necessary to find the reasons for these differences. Such studies will be helpful in improving the efficacy of the RNTCP. [ABSTRACT FROM AUTHOR]
