Predisposing factors for recurrent skin ulcers in leprosy.
This study was designed to determine the factors associated with recurrence of leprosy ulcers. Between April and August 1992, 55 consecutive leprosy patients admitted with skin ulcers were studied. Factors predisposing to recurrence, e.g. patient's age, disease duration, ulcer site, ulcer depth and physical deformity (taking into account neuromuscular and skeletal damage) were evaluated. Ulcer recurrence occurred in 40/55 (75%) patients. Recurrent ulceration was associated with location in the lower extremity (P = 0.02), where recurrences were more common in the midfoot and heel (P = 0.01). Recurrence was also associated with severity of physical deformity (P = 0.01), which increased the odds of recurrent ulceration by 4.2 times (95% confidence interval, 1.01-18.3). The severity of physical deformity itself was associated with the age of the patient (P = 0.04) and the disease duration (P = 0.02). In conclusion, there is a need to focus on identification of risk factors for recurrent leprosy ulceration. Targeted prevention strategies would be required if morbidity associated with recurrent skin ulceration is to be avoided.
