Introduction

Leprosy is caused by infection with Mycobacterium leprae. Neuropathy is often clinically silent, making early diagnosis exceptionally challenging. Nerve conduction studies (NCS) provide a more objective assessment of nerve function impairment (NFI).

Objectives

To emphasize the utility of NCS in determining NFI in leprosy patients and to highlight its role in preventing disability.

Materials and methods

Seventy-two untreated leprosy patients underwent NCS. Nerve parameters were measured at diagnosis and at 3, 6, 9, and 12 months of treatment. Mean values were analysed.

Results

69% of the patients and 29% of all the nerves examined showed NFI at the time of diagnosis. Sensory involvement (44%) predominated over motor involvement (15%), and the dierence was statistically signicant (P<0.001) at all intervals. The sural nerve (49%) and ulnar nerve (24%) were most frequently affected. In follow-up studies, improvement was observed more in motor nerves than in sensory nerves, but this was not statistically signicant (p=0.431 and p=0.945, respectively) at the end of one year. The sural nerve showed worsening (p=0.479). When comparing mean values of nerve parameters at 12 months, both improvement and worsening were observed.

Limitations

Predominantly male population and a narrow age range.

Conclusions

Our study is unique in utilizing NCS to assess the progression of neuropathy in leprosy patients undergoing MDT. NCS should be used for early diagnosis of neuropathy in leprosy patients and for the diagnosis of silent neuropathy, thus preventing disability and deformities
