OBJECTIVES: To compare the clinical, biochemical, radiological features and the outcome of elderly and young patients with tuberculosis. METHODS: Between 1980 and 1997, 83 patients diagnosed as having tuberculosis were treated in two departments of Internal Medicine and Geriatrics. They were divided into 42 young (< 65 years) and 41 elderly (> or = 65 years) patients and differences in presentation between the two groups were analysed. RESULTS: A past history of tuberculosis was found in 10% of young and in 18% of elderly patients (p = 0.43). Cancer was more often associated with tuberculosis in elderly patients (2% vs 15%, p = 0.09). The sites of disease were similar in both groups with 2/3 of pulmonary infection. Comparison of the presenting symptoms showed no significant difference for weight loss (52% vs 66%, p = 0.31), fever (52% vs 56%, p = 0.90) and cough (33% vs 32%, p = 1). The skin testing was positive for the majority of the young adults (84% vs 58%, p = 0.11). The commonly observed biochemical abnormalities in elderly patients were an increased erythrocyte sedimentation rate (49 vs 69 mm/h: p = 0.03) and lymphocytopenia (1724 vs 1059/microliter, p < 0.01). There was no significant difference in radiographic findings between both groups with miliary tuberculosis in about 10% of patients. During the first three months of treatment, the mortality was especially high (22%) for the elderly patients. CONCLUSIONS: Comparison of the clinical and radiological features of tuberculosis in internal medicine showed no significant difference in young and elderly patients.
