Evaluation of two multidrug regimen in hospitalised multibacillary cases.

Fifty three multibacillary leprosy cases were treated with two regimens of MDT L1 consisting of Rifampicin, Dapsone and Ethionamide and L2 consisting of Rifampicin, Dapsone and clofazimine. The results were compared at regular intervals and at the end of the study (24 months). Clinical inactivity, bacteriological negativity, ENL reactions, upgrading reactions were seen in L1 group in 65%, 4.54%, 50% and 41% of cases respectively while 65%, 25.8%, 30% and 45% respectively in L2 regimen group. Zero percent morphological Index was achieved in all cases in L1 regimen 90% in L2 regimen cases. No viability was found on mouse foot pad inoculation after 6 months in L1 while after 18 months in L2 cases.

A study of palmar ridge malformation in leprosy.

Palmar ridge malformation of 150 male leprosy patients (50 multibacillary and 100 paucibacillary) were compared with matched controls. Significantly high incidence of ridge malformation was found on the palms of multibacillary leprosy patients. The acquired ridge atrophy was found in 32% multibacillary leprosy, 4.5% paucibacillary leprosy and 0% controls. The congenital ridge dissociation was found in 46% multibacillary leprosy, 20% paucibacillary leprosy and 22% controls. The difference is statistically significant.

Clinico-histopathological evaluation of modified pilocarpine test in early diagnosis of leprosy.

Modified pilocarpine test was done in 112 patients of which 89 cases were under investigation (Group I) and 23 cases were confirmed tuberculoid leprosy cases (Group II). In group I, 70 cases (78.6%) showed deficient sweating of varying degree and 36 cases (40.4%) showed definite histopathological changes of paucibacillary leprosy in skin. 22 cases (95.6%) in Group II showed deficient sweating. 24 cases under investigation who had deficient sweating but did not show definite histopathological changes of leprosy initially were followed up for one year and at the end of one year 10 cases (41.6%) showed confirmatory changes of leprosy on histopathological examination. The modified pilocarpine test has been found to be a simple and very useful test in early diagnosis of leprosy.

Experience with multidrug therapy in paucibacillary leprosy.

Eighty paucibacillary leprosy cases were randomly put on two different multidrug regimens for 6 months followed by dapsone monotherapy. Regimen I was according to WHO (1982) recommendations consisting of Dapsone and six once a month rifampicin. In regimen II in addition to above two constituents, clofazimine was added 100 mg on alternate days. Dapsone thereafter was continued in both the regimens upto one year. The efficacy, acceptability and side effects of multidrug regimens were observed for a period of one year. Histopathological assessment was done on completion of multidrug therapy in all cases. A comparative evaluation of effect of two multidrug regimens in paucibacillary leprosy patients is reported. Addition of clofazimine over WHO (1982) recommended regimen appears to have no added benefit. The duration of WHO (1982) recommended regimens was found to be inadequate in many cases.

Cardiovascular system in leprosy.

Involvement of cardiovascular system (CVS) in 50 multibacillary (MB) and 20 paucibacillary (PB) cases of leprosy was evaluated. 20 age and sex matched controls were also studied. In addition to detailed clinical examination and resting electro-cardiogram, Master's two step exercise test (DMT) was also carried out to find out the occult and asymptomatic cardiac involvement. We have not found any significant symptomatic or electrocardiographic evidence of CVS involvement in various groups of leprosy.
