Clinical spectrum and outcomes of geriatric tuberculosis emergencies in North India.

Abstract

OBJECTIVES:Despite the acute and life-threatening repercussions that tuberculosis (TB) may have on the burgeoning older population in endemic countries like India, the spectrum of geriatric TB emergencies is not adequately understood.METHODS:We performed a prospective observational study at the emergency department of an academic hospital in north India between January 2019 and June 2020, investigating the clinical and laboratory features and outcomes of active TB in older patients aged 60 years and above.RESULTS:Out of 71 geriatric TB emergencies, central nervous system disease predominated (n = 41, 57.7%), followed by pulmonary (n = 16, 22.5%), pleural TB (n = 8, 11.3%), and multisite involvement (n = 6, 8.4%). Nearly 71.8% were male, and 77.4% belonged to low socioeconomic status (lower-middle or lower class). Usual predisposing factors were tobacco smoking (38.0%), chronic alcohol use (27.0%), and diabetes mellitus (23.9%). Atypical features were more frequent with extrapulmonary TB. Only 28.2% were microbiologically confirmed cases, and rifampicin resistance was seen in only one case. The mortality rate was considerably high (24.0%), highest with pulmonary TB (37.0%).CONCLUSION:Older patients with TB emergencies have atypical presentations, diagnostic difficulties, and high mortality.
