Background: Leprosy is a chronic granulomatous disease caused by Mycobacterium leprae. This debilitating disease mainly affects the skin, peripheral nerves, and eyes, which may lead to progressive damage if left untreated. We conducted this study to analyze the demographic trends and clinical profiles of leprosy patients registered at Mayo Hospital, Lahore.
Methods: A retrospective, observational study was conducted utilizing available medical records of all new leprosy cases diagnosed and registered in the leprosy clinic of the Dermatology Department, Mayo Hospital, over a five-year period. Data on demographic details (age, gender) and clinical presentations were collected and analyzed.
Results: From January 2019 to December 2023, a total of 122 new cases of leprosy were registered at Mayo Hospital’s Leprosy Department, showing a decreasing trend over the years. Among these, 64 (52.5%) were male, and 58 (47.5%) were female. Three patients (2.5%) were children (<14 years). Borderline tuberculoid (BT) leprosy was the commonest type, comprising 69 (56.6%) cases, followed by 30 (24.6%) cases of tuberculoid (TT) leprosy, 16 (13.1%) cases of lepromatous leprosy (LL), and 7 (5.7%) cases of borderline lepromatous (BL). According to the WHO classification, 30 (24.6%) were paucibacillary (PB), and 92 (75.4%) were multibacillary (MB). Two patients (1.6%) presented with a type 1 reaction, and four patients (3.3%) with a type 2 reaction. Moreover, 7 patients (5.7%) presented with grade 1 deformity and 20 (16.4%) with grade 2 deformity.
Conclusion: Despite a decreasing trend in leprosy cases, leprosy remains a public health concern in Pakistan with a predominance of multibacillary disease and a considerable proportion of patients presenting with disabilities. The presence of childhood cases further shows continued transmission. Strengthening early case detection, timely initiation of multidrug therapy, and heightened public health surveillance are vital to minimise deformity and interrupt disease transmission.
