One hundred fifty-one patients (125 males and 26 females) of multibacillary leprosy (LL 88, BL 40, BB 23), registered during 1986-1992 for multidrug therapy (MDT), were analysed with reference to their disabilities before, during and after MDT. At induction 48 (31.7%) had no disability (Gr 0), 59 (39.0%) had only peripheral anaesthesia (Gr 1) and 44 (29.1%) had Gr 2 and 3 deformities with or without anaesthesia. The parallel analysis of the three groups, with nearly equal duration of symptoms, revealed that new deformities developed in only a few cases during and after MDT, least in the Gr 0 group. The crude fresh deformity incidence was 59.2 per 1,000 person years of observation. The rate of recovery from anaesthesia was higher (64%) in Gr 1 group than that (44%) in group with Gr 2, 3 deformities. No significant difference was observed between the incidence of Gr 2 deformities developed before, during and after MDT (incidence of claw-hands 9.2% before and 7.9% during and after MDT, trophic ulcers 13.9% before and 17.8% during and after MDT). Out of 19 cases which developed motor weakness during MDT and follow-up, 10 (52.6%) were instances of quite nerve paralysis. Occupational factors influenced the development of deformities but not the sex and bacterial load. Generally, the lower the Grade of disability at induction of patient for MDT, the lower the chances of new disability development and higher the chances of recovery from sensory impairments.

In a hospital based study, 362 household contacts of multibacillary leprosy patients were screened for evidence of leprosy and 54 (14.9%) were found to be having leprosy. The remaining 308 apparently healthy contacts were lepromin tested and 109 (35.4%) were observed to be negative to Mitsuda lepromin. M.w vaccine was administered intradermally to 95 of these 109 lepromin negative contacts. Sixty eight of them could be retested for lepromin A reactivity. Fifty six (82.35%) manifested lepromin conversion. The twelve subjects who did not show lepromin conversion, received a second dose of the vaccine, and eleven subsequently became lepromin positive. The overall lepromin conversion rate was thus 98.5% (67 out of 68). Follow-up of these contacts upto a period of 30 months did not demonstrate reversion of lepromin positivity back to negativity status. No untoward effects of vaccination were observed except for local ulceration at the site of vaccine administration.
