Genetic diversity of Mycobacterium leprae: Need to move towards genome-wide approaches.

ABSTRACT: Leprosy, an ancient disease, continues to be a public health concern as it remains endemic in several countries. After reaching the elimination target (1/10,000) as a public health problem in 2005 in India, around 1.2 lakh cases have been detected every year over the last decade indicating active transmission of leprosy bacillus (Mycobacterium leprae). Single-nucleotide polymorphisms (SNPs), genomic insertions/deletions and variable-number tandem repeats (VNTRs) have been identified as genetic markers for tracking M. leprae transmission. As the leprosy bacilli cannot be cultured in vitro, molecular testing of M. leprae genotypes is done by polymerase chain reaction-based sequencing which provides a practical alternative for the identification of strains as well as drug resistance-associated mutations. Whole-genome sequencing (WGS) of M. leprae directly from clinical samples has also proven to be an effective tool for identifying genetic variations which can further help refine the molecular epidemiological schemes based on SNPs and VNTRs. However, the WGS data of M. leprae strains from India are scarce, being responsible for a gross under-representation of the genetic diversity of M. leprae strains present in India and need to be addressed suitably. Molecular studies of leprosy can provide better insight into phylogeographic markers to monitor the transmission dynamics and emergence of antimicrobial resistance. An improved understanding of M. leprae transmission is essential to guide efficient leprosy control strategies. Therefore, this review compiles and discusses the current status of molecular epidemiology, genotyping and the potential of genome-wide analysis of M. leprae strains in the Indian context.

Task sharing for the management of leprosy by nurses in a tertiary healthcare setting of Northern India.

BACKGROUND: This study aimed to assess the effectiveness of nurse-led interventions in managing leprosy due to a shortage of dermatologists and other healthcare professionals. METHODS: A total of 100 leprosy patients were divided into experimental (n=50) and control groups (n=50). The intervention included face-to-face counseling by a trained nurse, motivational videos and exercise demonstrations. The control group received standard care. The primary outcome of interest was treatment adherence (Adherence to Refills and Medications Scale); other assessed outcomes included changes in perceived stigma (Stigma Assessment and Reduction of Impact scale), depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder seven-item) and quality of life (WHO QOL-BREF Scale) from baseline to week 8. RESULTS: The intervention group had better treatment adherence (p<0.001). At baseline, moderately severe and severe depression prevalence was 18% and 28%, respectively, and anxiety was 25%, with no intergroup differences. Anxiety significantly decreased in the intervention group (p<0.001), but depression remained similar (p=0.291). Perceived stigma improved notably, especially in disclosure of concern (p<0.001), internal stigma (p<0.001) and anticipated stigma (p<0.001). Quality of life scores improved in the intervention group vs controls. CONCLUSION: Nurse-led interventions effectively enhanced quality of life and treatment adherence and reduced anxiety, depression and perceived stigma among leprosy patients. The study recommends strengthening the capacity of nurses for active involvement in leprosy care.

The Centenary of the Leprosy Relief Association (Lepra)-a moment for celebration and reflection†.

The year 2024 is the Centenary of the foundation of the Leprosy Relief Association (Lepra), formerly the British Empire Leprosy Relief Association (BELRA). The name of the organization changed to the LEProsy Relief Association (LEPRA) in 1976 but has been known as Lepra since 2008. Over the years it has worked closely with members and office holders of the Royal Society of Tropical Medicine and Hygiene. Its work has encompassed activities from the earliest initiatives to ensure appropriate living conditions for those with the disease to the development of leprosy chemotherapy. However, this has now evolved into a strong partnership between the UK- and India-based Lepra hubs, which are carrying out research and public health initiatives ranging from elimination of prejudice against those with leprosy to adopting the recently launched WHO programme for skin NTDs to facilitate integrated control and management regimens. The fight against leprosy has always been a partnership between a wide variety of disease-specific NGOs, health-care workers and international health agencies. The story of Lepra illustrates the central role of these partnerships and national as well as international collaboration.

Nutritional Status in Leprosy Patients: A Systematic Review and Meta-analysis.

BACKGROUND: Leprosy, a chronic mycobacterial disease, is frequently accompanied by malnutrition. However, it is important to regularly assess the nutritional state of leprosy patients in a resource-poor nation like India, where undernutrition is widespread. OBJECTIVES: This study aimed to compare the nutritional status of leprosy patients to that of normal individuals using the body mass index. METHODS: The electronic databases PubMed, Google Scholar, and Embase were used to conduct an open literature search. From 1st January 2000 to 31st January 2023, all articles were screened using the following MeSH terms: (nutrition OR body mass index OR body weight) AND (leprosy OR lepra) to find possibly relevant articles. RESULTS: This meta-analysis includes five research studies with a total of 1173 individuals (363 patients in the leprosy group and 810 patients in the non-leprosy group). The weighted mean difference (WMD) for BMI studies was -17.88 (95% CI -27.65 to -8.12), showing that there was a significant difference in BMI < 18.5 between leprosy patients and non-leprosy patients. There was a significant difference in DDS score and HFIAS score between patients with leprosy and non-leprosy. In a total of 342 leprosy patients, 206 developed deformities. CONCLUSION: This research increases our understanding of nutrition and leprosy. The results found that people with leprosy are nutritionally at a distinct disadvantage when compared to non-leprosy patients. It emphasises the several ways in which diet may generate circumstances that increase the risk of leprosy.

Novel mutations found in Mycobacterium leprae DNA repair gene nth from central India.

INTRODUCTION: The importance of DNA repair enzymes in maintaining genomic integrity is highlighted by the hypothesis that DNA damage by reactive oxygen/nitrogen species produced inside the host cell is essential for the mutagenesis process. Endonuclease III (Nth), formamidopyrimide (Fpg) and endonuclease VIII (Nei) DNA glycosylases are essential components of the bacterial base excision repair process. Mycobacterium leprae lost both fpg/nei genes during the reductive evolution event and only has the nth (ML2301) gene. This study aims to characterize the mutations in the nth gene of M. leprae strains and explore its correlation with drug-resistance. METHOD: A total of 91 M. leprae positive DNA samples extracted from skin biopsy samples of newly diagnosed leprosy patients from NSCB Hospital Jabalpur were assessed for the nth gene as well as drug resistance-associated loci of the rpoB, gyrA and folP1 genes through PCR followed by Sanger sequencing. RESULTS: Of these 91 patients, a total of two insertion frameshift mutations, two synonymous and seven nonsynonymous mutations were found in nth in seven samples. Sixteen samples were found to be resistant to ofloxacin and one was found to be dapsone resistant as per the known DRDR mutations. No mutations were found in the rpoB region. Interestingly, none of the nth mutations were identified in the drug-resistant associated samples. CONCLUSION: The in-silico structural analysis of the non-synonymous mutations in the Nth predicted five of them were to be deleterious. Our results suggest that the mutations in the nth gene may be potential markers for phylogenetic and epidemiological studies.

An evaluation protocol of 'Replicability Model' project for detection and treatment of leprosy and related disability in Chhattisgarh, India.

INTRODUCTION: People affected by leprosy are at increased risk of impairments and deformities from peripheral nerve damage. This mostly occurs if diagnosis and treatment is delayed and contributes to continued transmission within the community. Champa district of Chhattisgarh state in India is an endemic area with the highest national annual case detection and disability rates for leprosy. The Replicability Model is a system strengthening intervention implemented by the Leprosy Mission Trust India in Champa that aims to promote early diagnosis and treatment of leprosy, improve on-going management of the effects of leprosy and improve welfare for the people affected by leprosy. This protocol presents a plan to describe the overall implementation of the Replicability Model and describe the barriers and facilitators encountered in the process. We will also quantify the effect of the program on one of its key aims- early leprosy diagnosis. METHODS: The replicability model will be implemented over four years, and the work described in this protocol will be conducted in the same timeframe. We have two Work Packages (WPs). In WP1, we will conduct a process evaluation. This will include three methods i) observations of replicability model implementation teams' monthly meetings ii) key informant interviews (n = 10) and interviews with stakeholders (n = 30) iii) observations of key actors (n = 15). Our purpose is to describe the implementation process and identify barriers and facilitators to successful implementation. WP2 will be a quantitative study to track existing and new cases of leprosy using routinely collected data. If the intervention is successful, we expect to see an increase in cases (with a higher proportion detected at an early clinical stage) followed by a decrease in total cases. CONCLUSION: This study will enable us to improve and disseminate the Replicability Model by identifying factors that promote success. It will also identify its effectiveness in fulfilling one of its aims: reducing the incidence of leprosy by finding and tracking cases at an earlier stage in the disease.

High frequency of ofloxacin resistance patterns of Mycobacterium leprae from India: An indication to revisit second line anti-leprosy treatment regimen.

OBJECTIVES: Drug resistance in leprosy is an emerging concern, leading to treatment failures, recurrences, and potential spread of resistant Mycobacterium leprae in the community. In this study, we aimed to assess drug resistance prevalence and patterns amongst leprosy patients at a tertiary care referral hospital in India. METHODS: Mutations in drug resistance determining regions for dapsone, rifampicin, and ofloxacin of the M. leprae genome in DNA extracted from skin biopsies of 136 leprosy patients (treatment-naive = 67, with persistent skin lesions = 35, with recurrence = 34) were analysed by polymerase chain reaction followed by Sanger sequencing. Wild-type strain (Thai-53) was used as a reference strain. RESULTS: Resistance mutations were identified in a total of 23 patients, constituting 16.9% of the cohort. Within this subset of 23 cases, resistance to ofloxacin was observed in 17 individuals (12.5%), while resistance to both dapsone and rifampicin was detected in three patients each (2.2% for both). The occurrence of ofloxacin resistance showed minimal disparity between recurrent and treatment-naive cases, at 17.6% and 16.4%, respectively. Dapsone resistance emerged in two treatment-naive cases and one case with persistent skin lesions. Notably, none of the treatment-naive cases or those with recurrence/relapse exhibited rifampicin resistance. Subsequently, no statistically significant correlation was identified between other clinical variables and the presence of antimicrobial resistance. CONCLUSIONS: The occurrence of resistance to the current multidrug therapy regimen (specifically dapsone and rifampicin) and to ofloxacin, a secondary antileprosy medication in M. leprae, represents a concerning scenario. This calls for an expansion towards bactericidal drug options and the establishment of robust surveillance for drug resistance in countries burdened with high leprosy rates. Moreover, the introduction of stringent antimicrobial stewardship initiatives is imperative. As a single centre study, it represents a limited, cross-sectional view of the real situation in the field.

A history of thalidomide in India.

In contrast to the well-known stories of the embryotoxic drug, thalidomide, in countries where it was responsible for large numbers of birth defects, there is limited information on its history in India. Its presence before 2002, when the country issued the first marketing licence for a thalidomide-containing preparation, is assumed to be negligible. This article challenges this view by showing that the drug entered the Indian subcontinent through the former Portuguese territory of Goa around 1960. We examine the subsequent development of its distribution, use and regulation in India from the mid-1960s up to the present situation. Colonial legacies are a crucial explanation for the early appearance of thalidomide on the Indian subcontinent. They also influenced its re-emergence as drug for treating leprosy reactions in India after 1965. We identify key actors in this process: the original German producer that delivered thalidomide free of charge, European doctors who worked for international non-governmental organizations, the World Health Organization (WHO), which supported clinical trials and later discouraged the use of the drug, and finally the Indian state institutions that limited its distribution and later quickly opened the way for the private sector to produce and market thalidomide and its analogues. Finally, we discuss the risk of thalidomide-induced birth defects by casting a critical look on the present state of regulatory provisions and the monitoring of birth defects in India.

Application of CL Detect™ rapid test for diagnosis and liposomal amphotericin B for treatment of cutaneous leishmaniasis: A retrospective analysis from a tertiary care centre in a non-endemic area in India.

Background Increasing urbanisation has led to the occurrence of cutaneous leishmaniasis (CL) in new areas, which was otherwise localised to endemic areas. Healthcare workers should be made aware of this entity to ensure clinical suspicion of CL and investigations needed to confirm CL. The article describes patients seen at a tertiary hospital in Delhi. Aims To establish the utility of the CL Detect Rapid test as a diagnostic tool and the efficacy of Liposomal Amphotericin B (LAmB) for the complete cure of CL patients. Methods Data of patients of CL (n = 16) was retrospectively analysed concerning diagnosis and treatment. Diagnosis rested on histopathology, real-time PCR, and CL Detect Rapid Test. Speciation of the parasite was based on the Internal transcribed spacer-I gene. Patients were treated with LAmB (i.v., 5 mg/kg up to three doses, five days apart). Results A positivity of 81.3% (95%CI, 54.4-96) was observed for CL Detect Rapid test in comparison with 100% (95%CI, 79.4-100.0) for real-time PCR and 43.8% (95%CI, 19.8-70.1) for microscopy/histopathological examination. L. tropica was the infective species in all cases. All the patients treated with LAmB responded to treatment, and 9/10 patients demonstrated complete regression of lesions, while one was lost to follow-up. Limitations It is a retrospective study, and the data includes only confirmed cases of CL at a single centre. Conclusion This study highlights the utility of CL Detect as a promising diagnostic tool and the efficacy of LAmB for the complete cure of CL.

Dermatology journals from India: A critical appraisal of the journal metrics.

Background Bibliometrics refer to documents and citation-based measures that measure different aspects of performance of a journal, including impact, output and prestige. Objective The aim of this study was to collect bibliometric data of various Indian dermatology journals as well as Indian journals from other disciplines, in order to compare relative performances. Methods Journal metrics pertaining to various Indian journals, both from dermatology [Indian Journal of Dermatology, Venereology and Leprology (IJDVL), Indian Journal of Dermatology (IJD), Indian Dermatology Online Journal, Indian Journal of Pediatric Dermatology and International Journal of Trichology] and other disciplines [Indian Journal of Medical Research (IJMR), Indian Journal of Pediatrics (IJP), Indian Journal of Ophthalmology and Indian Journal of Pharmacology] were sought. Data pertaining to the following 8 metrics during the year 2021 was collected: Journal Impact factor, SCImago Journal Rank, h5-index, Eigenfactor score and normalized Eigenfactor Score, Journal Citation Indicator, Scimago Journal and Country Rank H-index, CiteScore and Source Normalized Impact per Paper. Results Among Indian dermatology journals, for the year 2021, IJDVL had the highest impact factor (2.217) and h-index (48). IJD led in terms of prestige metrics such as SCImago Journal Rank (0.403), Eigenfactor score (0.00231) and Source Normalized Impact per Paper (1.132). IJDVL underperformed with respect to an average dermatology journal on all three prestige metrics. Among selected journals from other disciplines, two (IJMR and IJP) had impact factor exceeding five, despite lagging behind IJDVL two years ago. Most had normalized scores exceeding 1, indicating better performance than an average journal from their respective fields. Limitations Non-inclusion of altmetrics related data Conclusion IJDVL is one of the leading Indian journals in the field of dermatology, followed closely by IJD. A rise in IJDVL influence is evident over the past decade, as evident by various metrics. However, the progress still trails behind the average of global dermatology journals as evident by the field-normalized journal metrics, indicating potential for further growth of journal influence.

Determinants of environmental quality in India: evidence using the bootstrapped ARDL model with structural breaks.

This current study examines the impact of renewable energy consumption, agriculture, and globalization on carbon emissions in India over the period from 1980 to 2018. For long-run estimates, we apply Gregory-Hansen's co-integration test, bootstrap ARDL approaches, fully modified ordinary least squares, and dynamic OLS. The empirical results of long-run estimates indicate that a 1% increase in renewable energy consumption, agriculture, and economic globalization will increase carbon emissions by 0.764%, 1.675%, and 0.517%, respectively. Moreover, this study confirms the detrimental effect of these variables on carbon dioxide emissions. Economic globalization coefficients indicate that the scale effect is valid in India. The 2002 economic crisis slowed down the country's growth rate, which reduced the ecological pollution. Several policy recommendations are derived from the empirical findings.

Little Doctors: Agents of change in Indian rural communities.

The child-to-child approach to health advocacy is one that draws on the strengths and agency of children to make a positive impact within their communities. The approach has been popularly used for health education in low- and middle-income countries. This article describes the 'Little Doctors' program that implemented the child-to-child approach in the towns of KC Patty and Oddanchatram, located in remote hilly regions of Tamil Nadu, India starting in 1986 to train middle- and high school children to respond to diseases prevalent in their communities along with practices for preventative measures. The program involved sessions that used a combination of creative instructional methods to engage students and provided take-home messages for them to act on with their families and community. The program was successful in creating a creative learning environment for children, offering a shift from the traditional methods of classroom instruction. Students who successfully completed the program were awarded certificates as 'Little Doctors' in their communities. Although the program did not conduct formal evaluations of the program effectiveness, students reported successfully recalling complex topics such as early signs of diseases like tuberculosis and leprosy that were prevalent in the community during the time. The program experienced several challenges and had to be discontinued despite its continued benefits to the communities.

Clinico-Epidemiological profile of new leprosy cases detected in leprosy case detection campaign in North Maharashtra during 2018-2020.

Leprosy is a leading cause of disability in India. The percentage of disability and deformity can be reduced by diagnosing leprosy at an early stage. In order to detect the hidden leprosy cases, leprosy case detection campaigns, on line with Pulse Polio Campaign have been introduced specifically for high endemic districts, by the Central Leprosy Division. Records of cases from 2018 to 2020 were evaluated retrospectively to study the trend of new cases. The present study denotes the presence of hidden undiagnosed cases in the community and will require an intensification of leprosy control activities through contact tracing and active case detection. Continued quality surveillance is required for early detection, timely management, and prevention of the spread of the disease.

Prevalence of onychomycosis in patients with diabetes mellitus: A cross-sectional study from a tertiary care hospital in North India.

Background Though diabetes mellitus (DM) is a well-recognised risk factor for onychomycosis (OM), the epidemiology of OM in diabetic patients remains largely unexplored, especially from the Indian subcontinent. Aims and objectives To estimate the prevalence of OM in diabetic patients, to identify and analyse risk factors, and correlate the severity of nail changes with glycemic control (HBA1c). Methods This cross-sectional, analytical study involved 300 diabetic patients. Patients with the clinical diagnosis of OM, supplanted by at least two of the four tests (KOH, culture, onychoscopy and nail histopathology) were considered cases of OM. Demographic and haematological profile was analysed using chi-square test/ Fischer's exact test. Logistic regression was applied to assess the independent risk factors. Results The prevalence of OM in DM patients was 34% (102/300) and significant risk factors included; age >60 years, male gender, closed shoes, disease duration >5 years, high BMI (>25) and lack of awareness about nail changes. Distal and lateral subungual OM (78%) was the commonest presentation followed by proximal subungual OM, superficial OM and total dystrophic OM. Correlation between HbA1c and the number of nails involved was found to be significant. Limitation As cases were recruited from a hospital setting, there could be chances of Berksonian bias. Conclusion The prevalence of OM in diabetic patients is high and the severity of nail changes correlates with HbA1C levels. It is important to diagnose OM early in order to treat and prevent complications.

Prevalence of post kala-azar dermal leishmaniasis (PKDL) and treatment seeking behavior of PKDL patients in Nepal.

BACKGROUND: In Nepal, the burden of post kala-azar dermal leishmaniasis (PKDL) is not known since there is no active case detection of PKDL by the national programme. PKDL patients could pose a challenge to sustain visceral leishmaniasis (VL) elimination. The objective of this study was to determine the prevalence of PKDL and assess PKDL patients' knowledge on VL and PKDL, and stigma associated with PKDL. METHODOLOGY/PRINCIPAL FINDINGS: Household surveys were conducted in 98 VL endemic villages of five districts that reported the highest number of VL cases within 2018-2021. A total of 6,821 households with 40373 individuals were screened for PKDL. Cases with skin lesions were referred to hospitals and examined by dermatologists. Suspected PKDL cases were tested with rK39 and smear microscopy from skin lesions. An integrated diagnostic approach was implemented in two hospitals with a focus on management of leprosy cases where cases with non-leprosy skin lesions were tested for PKDL with rK39. Confirmed PKDL patients were interviewed to assess knowledge and stigma associated with PKDL, using explanatory model interview catalogue (EMIC) with maximum score of 36. Among 147 cases with skin lesions in the survey, 9 (6.12%) were confirmed as PKDL by dermatologists at the hospital. The prevalence of PKDL was 2.23 per 10,000 population. Among these 9 PKDL cases, 5 had a past history of VL and 4 did not. PKDL cases without a past history of VL were detected among the "new foci", Surkhet but none in Palpa. None of the cases negative for leprosy were positive for PKDL. There was very limited knowledge of PKDL and VL among PKDL cases. PKDL patients suffered to some degree from social and psychological stigma (mean ± s.d. score = 17.89 ± 12.84). CONCLUSIONS/SIGNIFICANCE: Strengthening the programme in PKDL case detection and management would probably contribute to sustenance of VL elimination. Awareness raising activities to promote knowledge and reduce social stigma should be conducted in VL endemic areas.

Myths, misconceptions and attitudinal trends among patients with acne.

Background Despite acne being a common dermatological problem, there is a paucity of literature addressing the knowledge, attitude and practice about it. Aims/Objectives To find out what patients know about acne, its cause and treatment, as well as myths, misconceptions and attitude towards it. Methods A cross-sectional, descriptive questionnaire-based study on acne patients at Maharana Bhupal Hospital, RNT Medical College, Udaipur, Rajasthan, India. Results Most (84.8%) patients belonged to the age group of 16-25 years. The majority (63.9%) presented 12 months after the onset of acne. More than half had average knowledge, a positive attitude and good practices, related significantly to gender and education. Limitations A standardized questionnaire suitable for all dialects and regional languages would have yielded more uniform results. Conclusion Study revealed that acne patients still need to acquire accurate, adequate and easily accessible information to seek timely and appropriate treatment, and alleviate their psychological suffering.

Fractional CO2 laser with topical 1% terbinafine cream versus oral itraconazole in the management of onychomycosis: A randomized controlled trial.

Background Onychomycosis accounts for 20-40% of all nail disorders. It is difficult to cure with resistance to anti-fungal drugs, their side effects and drug interactions limiting treatment options. Itraconazole is a widely accepted oral medication used for onychomycosis while fractional CO2 laser along with a topical anti-fungal has shown promising results for nail plate clearance in onychomycosis. Aim To compare the efficacy of fractional CO2 laser with 1% terbinafine cream versus itraconazole in the management of onychomycosis. Methods A prospective, randomised, single-centre, two-arm, parallel-group interventional study was conducted at Command Hospital Air Force, Bangalore. Onychomycosis cases confirmed by KOH mount/culture-positive were included. Patients were randomly divided into two groups. Group A received 4 sessions of fractional CO2 laser every fourth week with twice-daily application of 1% terbinafine cream; Group B received one-week pulse therapy with capsule itraconazole once every four-week for three pulses. The response was assessed by Onychomycosis Severity Index, a validated onychomycosis assessment scale, at baseline and at six months. Results Group A had 50 patients with a total of 98 nails. Clinical improvement was seen in 83/98 (84.7%) nails. The average reduction in Onychomycosis Severity Index was 8.65 (P < 0.05). Group B had 50 patients with a total of 136 nails. Clinical improvement was seen in 104/136 (76.5%) nails. The average reduction in Onychomycosis Severity Index was 7.37 (P < 0.05). Both groups showed statistically significant improvement measured by 'Reduction in Onychomycosis Severity Index' at six months; however, there was no significant difference between the two arms. Limitations The main limitations of the study are the small sample size and lack of long-term follow-up to assess recurrence of infection. Conclusion Fractional CO2 laser with 1% terbinafine cream is an effective and safe method for inducing nail clearance in onychomycosis and has efficacy similar to itraconazole pulse therapy.

Determinants of patients' delay with disability in the diagnosed leprosy cases in the three major states of India: A case-control study.

BACKGROUND: Skin lesions are the most common early symptoms of leprosy, often ignored by patients at an early stage and misdiagnosed as other dermatological diseases by healthcare personnel, leading to delay in diagnosis and treatment of leprosy precipitating permanent neurological deficit, deformities and serious disabilities. AIMS: The objective is to evaluate the duration of delay and factors responsible for the delay in reporting of patients, among the newly detected leprosy cases (Grade 1 and Grade 2 disability patients). METHODS: A case-control study was conducted during 2014-2016 in three major states of India (Delhi, Gujarat and West Bengal) in 140 randomly recruited newly registered adult leprosy patients (aged 18 years and above) with Grade 2/1 disabilities (cases) and 140 Grade 0 disability patients (controls) in each of these Indian states. RESULTS: It is established that the major contributors for the delay in the early diagnosis of leprosy have been patient-related factors. The median patient delay in the three states of Delhi, Gujarat and West Bengal were five months (0.7-1.8), 2.8 months (2-14) and 12 months (2-24), respectively. LIMITATIONS: The study design is case-control and has an inbuilt reporting bias due to the retrospective nature of data collection but the data collection was carried with caution to reduce the recall bias. As the study is carried out in three states, generalisation of interpretation was cautiously executed. The matching ratio of cases and controls was 1:1 in this study, but we could not increase the controls due to operational feasibility during the conduct of the study. CONCLUSION: Patient delay is a crucial factor responsible for the disability among new leprosy cases. A higher patient delay in these three states reflects that the community is not aware about the signs and symptoms of leprosy. Reducing patient delay is very important for reducing disabilities in the newly diagnosed cases.
