Abstract

BACKGROUND:

The incidence of tuberculosis is high in chronic kidney disease (CKD) which needs a high index of suspicion, early diagnosis and management for gratifying outcome.

MATERIALS:

The clinical, laboratory profile, management and outcome of tuberculosis in 36 patients with chronic kidney disease between 2000 and 2005 constitute the material of this study.

RESULTS:

During this study period, over 900 chronic renal failure patients were evaluated in our unit and 36 of them were found to have tuberculosis, the incidence being 4%. In majority (69.4%), tuberculosis was observed in association with CKD Stage V. Age range was 25 - 77 years, male : female ratio was 33 : 3. Fever, malaise and weight loss were the commonest symptoms observed at presentation. Extrapulmonary tuberculosis (23 patients, 63.8%) predominated over pulmonary tuberculosis (10 patients, 36.1%). Tuberculin skin test was negative in 23 patients (63.8%). The diagnosis of tuberculosis was confirmed by tissue or specimen examination in 17 patients (47.2%) and in the rest it was empirical basing on clinical picture, pleural fluid analysis and radiological tests. All the patients were planned for a minimum period of 9-month antituberculous therapy (ATT). Of them, 17 patients (47.2%) were cured from tuberculosis and did not relapse, 9 patients (25%) died during treatment and 10 patients were lost for follow-up. Two patients were managed for anti-tuberculous therapy-related side effects: hepatotoxicity and psychosis.

CONCLUSIONS:

We observed a 4% incidence of tuberculosis in CKD. Extrapulmonary form of tuberculosis predominated over pulmonary form. Fever and malaise were important clues for suspicion of tuberculosis. Tuberculin skin test was negative in the majority. Diagnostic confirmation was possible in 47.2% of patients and in the rest it was based on clinical suspicion, pleural fluid analysis and radiological findings. Cure from tuberculosis was observed in 47.2% of patients with antituberculous therapy.
