The effect of corticosteroids usage on bacterial killing, clearance and nerve damage in leprosy; part 3--Study of two comparable groups of 100 multibacillary (MB) patients each, treated with MDT + steroids vs. MDT alone, assessed at 6 months post-release from 12 months MDT.

Objective: To investigate effects of therapeutic usage of corticosteroids on M. leprae killing and clearance, on clearance of granuloma and on nerve damage in multibacillary (MB) leprosy patients.

Design: From a cohort of 400 untreated MB patients, a comparable group of 100 each receiving MDT + steroids (group A) vs MDT alone (group B) were assessed at 18 months as compared to month zero with respect to clinical and granuloma regression, M.

Effect of corticosteroid usage combined with multidrug therapy on nerve damage assessed using nerve conduction studies: a prospective cohort study of 365 untreated multibacillary leprosy patients.

The purpose of this study is to determine the extent of nerve involvement and to study the effect of corticosteroids combined with multidrug therapy on nerve damage in leprosy patients using sensory and motor nerve conduction studies. A cohort of 365 untreated multibacillary leprosy patients were prospectively studied using sensory and motor nerve conduction studies on upper and lower limb nerves. They were subgrouped as those to be treated with 12-week regimen of corticosteroids for reaction and/or neuritis or silent neuropathy of <6 months duration along with 12-month multidrug therapy (group A), and those with no reaction were treated with multidrug therapy only (group B).

Sensitivity and specificity of nerve palpation, monofilament testing and voluntary muscle testing in detecting peripheral nerve abnormality, using nerve conduction studies as gold standard; a study in 357 patients.

Objective: To determine sensitivity and specificity of clinical tools viz. nerve palpation (NP), monofilament (MF), and voluntary muscle testing (VMT), for assessing peripheral nerve function impairment (NFI) in leprosy, using nerve conduction studies (NCS) as gold standard.

Study Population And Methods: 357 untreated multibacillary (MB) leprosy patients were assessed using above tests.

The effect of corticosteroid usage on the bacterial killing, clearance and nerve damage in leprosy: a prospective cohort study: part 1--study design and baseline findings of 400 untreated multibacillary patients.

Objective: To investigate possible adverse effects of therapeutic usage of corticosteroids on the killing and clearance of M. leprae and the clearance of granuloma, in patients with multibacillary (MB) leprosy.

Design: A cohort of 400 untreated MB patients were sub-grouped into those to be treated with corticosteroids (prednisolone 40 mg daily tapered to 5 mg over 12 weeks) along with MB-MDT for reaction and/or neuritis or silent neuropathy (SN) of <6 months duration (group A), and those with no reaction and to be treated with MDT only (group B).
