Leprosy case detection using schoolchildren.

An innovative method that combined awareness creation with screening of high school students by their peers was undertaken in 26 randomly selected schools in the project area of the Schieffelin Leprosy Research and Training Center, Karigiri, Vellore, India. This method entailed educating teachers and student leaders in grades 8-12 about leprosy and how to suspect leprosy among their peers. The student leaders in turn conducted a similar awareness programme for their peers and encouraged them to report if they suffered from any skin problem or skin lesion. Based on the reporting by their peers, the class leaders prepared a 'suspect list'. Within a fortnight of the awareness program, a trained leprosy worker visited the school and examined all the students on the 'suspect list'. Those diagnosed to have leprosy were referred to a medical officer, who then confirmed the diagnosis and initiated treatment. Among the 23,125 students enrolled in the 26 randomly selected schools, 234 student leaders were educated about leprosy and trained to detect suspect lesions among their peers. A total of 2200 (9.5%) children reported with skin lesions to their leaders and after screening by a leprosy supervisor and confirmation by a medical officer, 14 new cases (NCDR 6.05/10,000) were detected. This rate was found to be comparable with case detection rates of annual school surveys done during the National Leprosy Eradication Programme (NLEP), when all schoolchildren were examined. The paper suggests that schoolchildren can be used effectively in leprosy case detection and this method has the additional advantage of creating awareness among them, their teachers and communities.

Impact of leprosy on the quality of life.

Leprosy is considered by many as not merely a medical condition, but as a condition encompassing psychological, socioeconomic and spiritual dimensions that dehabilitate an individual progressively, unless properly cared for. The present study was undertaken to document the nature and extent of decreases in the quality of life (QOL) of an affected person. The World Health Organization questionnaire on quality of life was given to a representative random sample of 50 leprosy-affected persons and 50 unaffected individuals in the Bommasamudram Taluk of Chittoor District, Andhra Pradesh, India. This questionnaire explores the following six domains; physical; psychological; level of independence; social relationships; spiritual; and environmental. The mean QOL score of the cases was significantly lower than that of the controls with the exception of the spiritual domain. The mean total score for women was higher than that of males in each domain and age group. Males with deformities had a significantly lower score than those with no visible deformities. Although the scores for females with deformities were also lower than those without deformities, the differences were not statistically significant. Analyses of economic status versus the QOL scores clearly showed that they were positively correlated. The study revealed that quality of life decreased progressively in leprosy-affected persons. Women had a better QOL score than men in almost every domain. Given the secondary role of women in Indian rural society, this may simply imply an acceptance of their situation. The findings are discussed in comparison with other diseases and in the context of a poor socioeconomic environment. With modern amenities, better education and higher expectations, the perception of an individual regarding his or her own quality of life is bound to change. The need for frequent assessments and further studies along these lines is emphasized.

Epidemiological significance of first skin lesion in leprosy.

The epidemiological significance of monolesions in leprosy and the possible inferences on the mode of entry by Mycobacterium leprae into the body are presented based on data from the clinical records of the Leprosy Control Programme of Gudiyatham Taluk in India; 660 children with monolesions (335 males, 305 females) younger than 15 years of age and detected during the period 1990-1995 were included in the study. Detailed investigations on the location of monolesions were carried out and compared with a random sample of 669 normal rural children matched for age and sex. A large majority of the leprosy monolesions were in the uncovered parts of the body, with special predilection for the posterior aspects of the upper extremities and the anterior aspects of the lower extremities. Based on observation of normal children, these happen to be precisely the sites vulnerable for trauma since they are exposed to the environment where M. Leprae could enter through abraded skin and manifest as a patch. The need for further studies is emphasized.

Genomic MHC haplotyping of mutant cell lines using a novel marker.

The aim of this study was to characterize MHC mutant cell lines by studying haplospecific markers within the MHC and specifically in the 250 kilobase (kb) region between the HLA B and TNF loci. This region has been difficult to define because of the lack of appropriate markers. Spontaneous MHC mutants were isolated after immunoselection with an anti-HLA A2 monoclonal antibody and complement. Ten mutants were characterized using serological or allelic and genomic DNA markers within the HLA A to HLA DQ region of the MHC. Most mutants lost at least the 3 megabases of DNA from HLA A to HLA DQ viz the whole haplotype carrying HLA A2. Variants which have lost either HlA A alone or HLA A and HLA B were also found. The results show that it is possible to map the extent of the deletion between HLA B and TNF. Haplospecific scanning patterns for the CL region appear particularly useful.

Being a female leprosy patient in south India.

The problems of women patients as revealed by a case study of a woman patient and a questionnaire study of 100 leprosy patients (47 men and 53 women) are presented. These include, besides general ones like ignorance of facts about the disease, specific ones like lack of privacy during clinical examination, indifference towards women's feelings and difficulties in communicating with male workers. A greater sensibility towards the sentiments and problems of women patients, on the part of the health service is required to amend the situation. Recruiting more women workers might help in this regard.

Drug resistant-Mycobacterium leprae--results of mouse footpad studies from a laboratory in south India.

Out of 265 biopsies of leprosy patients received at the Experimental Pathology Laboratory of Schieffelin Leprosy Research and Training Centre from 1987 to 1997 for evaluating resistant strains of M. leprae, using the mouse footpad technique, 49 showed resistant strains of M leprae to varying concentrations of dapsone, rifampicin and clofazimine. 23 (47%) of these were from a control area. With 369 skin-smear positive multibacillary (MB) patients as the risk group (denominator), 23 (6.23%) were resistant to one or more drugs. 18 (4.88%) had dapsone resistance, 5 (1.36%) were resistant to rifampicin and 9 (2.44%) had resistance to low concentrations of clofazimine (0.0001%). Out of the 23 biopsies with drug resistance from the control area, primary dapsone resistance was seen in 7 (30%) biopsies and secondary dapsone resistance in 11 (48%). Primary rifampicin resistance was seen in 4 (17.4%) patients, secondary rifampicin resistance in 1 (4.35%) and primary clofazimine resistance in 7 (30%). 3 (13%) of the strains showed secondary clofazimine resistance. One biopsy had resistant strains to all the three drugs. In a control area where properly supervised effective multidrug therapy (MDT) was regularly administered over the years, the emergence of drug resistance is negligible. It may not be the case if the content, duration and regularity of the drug regimen were not satisfactory. Aware of the possible shortcomings in mass administration of MDT, it is emphasized that mouse footpad studies on drug resistance should be made available at least in endemic areas where the incidence of the disease has not changed despite good MDT coverage in order to monitor the emergence of drug resistance. Research into molecular biological identification of drug resistant-M.leprae should be intensified. These steps would help to institute timely measures to check the spread of any drug-resistant organisms in the community.
