Tuberculosis in Elderly Population: A Cross-Sectional Comparative Study

Background: Tuberculosis (TB) is a common but neglected infectious disease of global significance. It has a varied presentation in the elderly compared to adults. The present study was conceived to study the resemblances and differences shared in terms of clinical profile, comorbidities, and laboratory investigations by TB in adults and the elderly population. Methods: In this cross-sectional study, 68 adults and 72 elderly patients of both genders were enrolled. We collected information on demographics, comorbidities, clinical presentations, and laboratory investigations. The comparison of data between groups was done using the unpaired t-test for continuous variables and the Chi-square test for frequency distribution analysis. Results: The mean age of the adults and elderly population was 42.13 +/- 10.7 years and 68.78 +/- 7.62 years, respectively. The elderly TB group demonstrated loss of weight, appetite, the prevalence of comorbid conditions (coronary artery disease, hypertension, and malnutrition), bilateral, predominantly lower lobe, and diffuse involvement of lungs. Conclusion: As the elderly population increases, nonspecific clinical manifestations or laboratory results in this population mandate awareness of these atypical features for effective management of TB in this group.
