Dr. Dharmendra's Enduring Influence on Leprosy: From Laboratory to Disease Control.

A stalwart of Indian dermatology, Dr. Dharmendra was particularly known for his breakthrough research on leprosy. Spanning over several decades, his work was marked by significant contributions, including the development of Dharmendra's lepromin, which served as a critical diagnostic tool and in advancing the understanding of immunological aspects of leprosy. Born in 1900 in present-day Pakistan, his early education and work experiences set the foundation for his later achievements in leprosy research. Despite the social stigma associated with the disease at the time, Dr. Dharmendra's dedication led him to take up key roles, such as the first director of the National Leprosy Control Programme and head of the Central Leprosy Teaching and Research Institute in Chengalpattu. His work significantly impacted leprosy control efforts in India. ⁤⁤His legacy was further cemented by his leadership in founding the Indian Association of Leprologists and his tireless editorial work in the Indian Journal of Leprosy. Through his publications and ongoing research, even after retirement, he continued to influence the field. Dr. Dharmendra's life and work remain a cornerstone of leprosy research, inspiring future generations. His legacy continues to be felt in the ongoing efforts to combat leprosy.

Knowledge and Practices toward Tuberculosis Case Identification among Accredited Drug Dispensing Outlets Dispensers in Magu District, Northwestern Tanzania.

Accredited Drug Dispensing Outlets dispensers (ADDO dispensers) have a crucial role in detecting and referring TB suspects. However, several studies highlight low knowledge of TB among ADDO dispensers. To facilitate this, the National TB and Leprosy Control Program trained ADDO dispensers on case identification and referral. Hence, this was a community-based cross-sectional study to determine the knowledge and practice of ADDO dispensers in the detection of active tuberculosis suspects in Magu Districts, Mwanza, Tanzania. This was a cross-sectional study that included 133 systematically selected ADDO dispensers. Out of 133 ADDO dispensers, 88 (66.9%) had attended TB training. About 108 (81%) participants had good knowledge of TB. The majority of ADDO dispensers 104 (78.4%) had poor practice toward the identification of TB cases. Attending training (AOR 4.49, CI 1.03-19.47), longer working experience (AOR 4.64, CI 1.99-10.81), and the presence of national TB guidelines (AOR 3.85, CI 1.11-13.34) was significantly associated with good self-reported TB case identification practices. Therefore, the study revealed adequate knowledge but with poor practice. Provisions to train ADDO dispensers in tuberculosis case detection and referral could yield great results.

Leprosy has been prevalent in India for a very long time. To control the prevalence rate (PR) of leprosy in India, Government of India (GOI) launched “National Leprosy Control Programme (NLCP)” with Dapsone monotherapy in 1955. The PR in 1983 was 57/10000 population. In 1983 GOI launched “National Leprosy Eradication Programme (NLEP)” with "Multi Drug Treatment (MDT)”. PR came down to <1/10000 population in 2005. World Health Organization (WHO) declared leprosy was eliminated from India in 2005. Clinicians all over India are diagnosing leprosy cases and treating them. Multi Bacillary (MB) and Pauci Bacillary (PB) cases are commonly detected. Detection of new cases reminds us that transmission of leprosy is still active in the community. We are reporting a case of leprosy. Keywords: GOI, NLCP, NLEP, MDT, WHO, MB, PB

Challenges Experienced and Observed during the Implementation of Leprosy Strategies, Sidama Region, Southern Ethiopia: An inductive thematic analysis of qualitative study among health professionals who working with leprosy programs.

Prompt diagnosis and treatment of leprosy are crucial for preventing the disease's spread as well as for avoiding negative medical and social effects and reducing the disease's burden. The likelihood of nerve damage and subsequent disability rises as the length of the diagnostic delay. We aimed to explore the challenges of health professionals faced regarding their involvement in early leprosy case detection strategies. The study employed a qualitative, descriptive and phenomenological explorative research design to answer the research questions. By the use of non-probability purposive sampling, research participants were identified. During the study, in-depth interviews were conducted to gather information regarding the experiences of health workers (medical doctors, public health officers, clinical nurses, health centre heads and regional and Woreda district health office technical and programme experts) and health extension workers. To analyse the qualitative data, inductive thematic analysis techniques were used. For analysis, open code software version 4.0 was used. The data transcription, coding, display, reduction (theme) and interpretation of the discovered results were the processes undertaken for the analysis. The findings of the study revealed that leprosy prevention and control programmes are still problematic. Themes that emerged from the data gleaned from the health workers included: lack of the existence of practice-oriented training, Integration of TB and leprosy training, lack of focus or other competing health priorities, Inadequate supportive supervision of health facilities, Multiple tasks for health workers, poor coordination and communications, lack of motivation in health workers, disruption in treatment, and Importance of training related to leprosy. Strengthening comprehensive leprosy training for health workers, carrying out efficient and thorough contact tracing, enhancing monitoring, supervision, assessment and surveillance, boosting managerial skills, lobbying political commitment, and motivating healthcare workers may help in early detection of leprosy cases strategies.

Childhood Leprosy in Postelimination Era: A Clinico-Epidemiological Prospective Observational Study from India

Background: Although India has achieved national level elimination of leprosy in December 2005, it reports highest number of leprosy cases in the world. Incidence of leprosy amongst young children indicates active foci of transmission in the community, making it a robust epidemiological indicator to assess the progress of leprosy control programs. Aim and Objectives: To study prevalence, clinical spectrum, patterns of extracutaneous involvement, reactions, relapse, demographic profile, anthropometric characteristics of children with leprosy. Materials and Methods: A prospective observational study of children younger than 14 years old with clinical signs and symptoms of leprosy, including cases diagnosed from October 2018 through September 2020 at a tertiary hospital in Eastern India. Results: Childhood leprosy constituted of 10.4% of total new leprosy cases. Mean age observed was 11.14 ± 1.5 years. 30.4% were females and 69.6% were males. The mean average duration was 9.95 ± 12.3 months. 82.1% of children belong to below poverty line (BPL) status. 19.6% of children had malnourishment/stunting/thinness, and 55.4% had anemia. 84.1% presented with skin discoloration. The most common site affected was upper limb (57.1%). 29.2% had contact history. A single case of relapse (1.7%) was reported. Most common peripheral nerve involved was ulnar nerve (67.8%). 8.9% of children had type 1 lepra reaction, and 1.7% had type 2 lepra reaction. 73.21% presented with borderline tuberculoid clinical type of leprosy. 19.6% showed slit skin smear positivity. Conclusion: Pockets of high endemicity of childhood leprosy as detected in the current study point toward the unmet need of better healthcare facilities along with increased awareness, campaigns, and school surveys for early diagnosis and treatment for the prevention of complications and spread in community.

Integrative Health Promotion Model in Leprosy Prevention and Control Programs to Improve Quality of Life for Leprosy Survivors

Objective: Leprosy is an infectious disease that causes highly complex problems from the medical aspect to social, economic, cultural, security, and national defence issues. This research aimed to develop and analyse the effect of an integrative model on leprosy prevention and control programs to improve the life quality of leprosy survivors. Materials and Methods: This research was conducted in Madura, East Java, Indonesia. The study consists of 360 leprosy survivors. The exposed group in this study was a group of leprosy survivors living within the areas of the Ministry of Health's leprosy program, a total of 180 leprosy survivors. The unexposed groups were leprosy survivors living around the areas with the absence of Ministry of Health leprosy program, a total of 180 leprosy survivors. Results: The quality of life has a direct and positive relationship with health status (b= 0.56 ; 95% CI = 0.14 to 1.00; p=0.010), health status has a direct and positive relationship with healthy behavior (b= 0.55 ; 95% CI = 0.10 to 1.00; p=0.016), healthy behavior has a direct and positive relationship with self-efficacy (b= 0.91 ; 95% CI = 0.38 to 1.44; p=0.001), healthy behavior has a direct and positive relationship with family support (b= 0.54; 95% CI = 0.06 to 1.03; p=0.029), healthy behavior has a direct and positive relationship with attitude (b= 0.56 ; 95% CI = 0.05 to 1.09; p=0.032). Conclusion: Health status, healthy behavior, self-efficacy, family support, attitude and community support related to improving quality of life for leprosy survivors.

Measuring leprosy case detection delay and associated factors in Indonesia: a community-based study

BackgroundLeprosy is a public health burden in Indonesia with a high number of new cases every year and a high proportion of disability among new cases. Case detection delay (CDD) can contribute to ongoing transmission and increased disability chances among leprosy patients. This study aimed to establish the CDD of leprosy and the factors associated with detection delay in Indonesia.MethodCommunity-based study with a cross-sectional design. Data were collected through interviews about sociodemographic and behavioral factors, anticipated stigma, and duration of CDD. Leprosy classification and case detection methods were obtained from health service records. A random sample was taken of 126 leprosy patients registered between 1st October 2020 and 31st March 2022 in the Tegal regency in the Central Java Province. Data were analysed by descriptive and analytical statistics using multiple linear regression.ResultsThe mean CDD, patient delay, and health system delay were 13.0 months, 9.7 months, and 3.2 months, respectively. Factors associated with longer CDD are younger age (below 35 years), male, found through passive case detection, and not having a family member with leprosy. Factors associated with longer patient delay were being younger (below 35 years), being male, not having a family member with leprosy, and anticipated stigma of leprosy. It was not possible to reliably identify factors associated with health system delay.ConclusionCDD in leprosy should be reduced in Indonesia. The Indonesian National Leprosy Control Program (NLCP) is advised to adopt an integrated intervention programme combining active case detection with targeted health education to reduce CDD and thereby preventing disabilities in people affected by leprosy.

Prediction of the occurrence of leprosy reactions based on Bayesian networks.

Leprosy reactions (LR) are severe episodes of intense activation of the host inflammatory response of uncertain etiology, today the leading cause of permanent nerve damage in leprosy patients. Several genetic and non-genetic risk factors for LR have been described; however, there are limited attempts to combine this information to estimate the risk of a leprosy patient developing LR. Here we present an artificial intelligence (AI)-based system that can assess LR risk using clinical, demographic, and genetic data. The study includes four datasets from different regions of Brazil, totalizing 1,450 leprosy patients followed prospectively for at least 2 years to assess the occurrence of LR. Data mining using WEKA software was performed following a two-step protocol to select the variables included in the AI system, based on Bayesian Networks, and developed using the NETICA software. Analysis of the complete database resulted in a system able to estimate LR risk with 82.7% accuracy, 79.3% sensitivity, and 86.2% specificity. When using only databases for which host genetic information associated with LR was included, the performance increased to 87.7% accuracy, 85.7% sensitivity, and 89.4% specificity. We produced an easy-to-use, online, free-access system that identifies leprosy patients at risk of developing LR. Risk assessment of LR for individual patients may detect candidates for close monitoring, with a potentially positive impact on the prevention of permanent disabilities, the quality of life of the patients, and upon leprosy control programs.

Improved leprosy elimination efforts in Somalia, 2015–2021: achievements in a challenging environment and the way forward

Background Since leprosy was eliminated as a public health problem in 2000, trends in case detection have been declining. However, from 2015, case detection in the WHO Eastern Mediterranean (EM) region increased mainly due to reports from Somalia that re-instated the national programme. As Somalia reported 57% of new cases in the EM region in 2021, we reviewed the national control programme activities and the characteristics of reported cases to understand leprosy transmission in the country. Methods From 2012 to 2021, we extracted data from WHO’s Global Health Observatory and the national leprosy control programme’s patient register in Somalia. From 2015 onwards, leprosy cases were detected by the Federal Ministry of Health through mobile teams conducting “skin camps” in 47 districts across seven regions. We analyzed data to describe the overall case detection rate and rates per period, place and person, including severity measured by grade two disability (G2D) and multibacillary (MB) cases. Results The overall case detection rate increased 11-fold between 2012 and 2021, from 6 cases per million in 2012 to 106 cases per million in 2021 in females and from 16 cases per million in 2012 to 132 cases per million in 2021 in males. Case detection among children under 15-years of age also increased from 4 cases per million in 2012 to 13 cases per million in 2021. Initially, the proportion of MB cases and G2D at the time of diagnosis increased from 60% and 11% in 2012 to 87% and 42% in 2015 respectively, when the national programme resumed leprosy control activities. By 2021, the MB proportion decreased to 45% and G2D proportion also decreased to 2%. From 2015 to 2021, four regions in Somalia reported 77% of the new cases and 83% of cases with G2D: Lower Shabelle, Middle Juba, Lower Juba and Middle Shabelle. Conclusion “Skin-camps” for case detection were effective in finding hidden leprosy cases and reducing the delay in diagnosis over time. The constant case detection rate among the female population, equal to the male population, points to sufficient programme reach. However, low disability rates persisted among this population which could be due to continued underlying stigma. Reports of new cases among children suggest ongoing transmission requiring prevention strategies such as single dose rifampicin post-exposure prophylaxis.

Tuberculosis management and referral practices among traditional medicine practitioners in Lagos, Nigeria.

Despite the potential role of Traditional Birth Attendants (TBAs) and Traditional Healers (THs), little is known about their knowledge of tuberculosis (TB) management and referral practices in Nigeria. To determine knowledge and self-reported practices of traditional birth attendants and traditional healers in managing TB in Lagos, Nigeria. A cross-sectional study of 120 THs and TBAs in three high TB burden Local Government Areas (LGAs) in Lagos, Nigeria. Data were collected between April 2018 to September 2018 through interviewer-administered questionnaires. We used Statistical Package for Social Sciences software for data analyses. Independent predictors of being TBA or TH were determined using logistic regression at the statistical significance of P<0.05 and 95% confidence interval. TB knowledge increased from 52.7% pre-test to 61.7% post-test and did not differ between TBAs and THs. Of the 120 Traditional Medical Practitioners studied, 70% (84) never treated TB; 57.3 % (69) ever referred chronic cough patients to a health facility; 90% (108) were willing to collaborate with National Tuberculosis, Leprosy and Buruli Ulcer Control Programme (NTBLCP), 85% (102) attached monetary and token incentive as a condition for the collaboration. THs had decreased odds of ever referring TB patient to the hospital (AOR: 0.3, 95% CI:0.14-0.64, P=0.002); currently referring TB patients (AOR: 0.06, 95% CI:0.02-0.17, P<0.0001) and consulting <40 patients in a year (AOR: 0.22,95% CI:0.09-0.53, P<0.0001). Majority of the THs and TBAs were willing to collaborate with NTBLCP in the identification and referral of Presumptive TB patients. We suggest that NTBLCP empowers the TBAs and THs to help with an early referral of TB patients.

The application of digital health as a nursing solution for leprosy patients during the COVID-19 pandemic: a systematic review

To analyse the effect of using digital health technology on leprosy control programmes. The systematic review comprised search on PubMed, Scopus, ScienceDirect, SAGE and ProQuest databases for interventional studies published in English language from 2013 to 2021 which used digital health technology for leprosy contact tracing, active leprosy detection, monitoring of multi-drug therapy and treatment management during the corona virus disease-2019 pandemic A standard risk of bias tool was used to evaluate bias in the studies, and the Joanna Briggs Institute protocol was used to assess the quality of the studies analysed. Of the 205 studies initially identified, 15(7.3%) were analysed in detail. Quasi-experimental studies had a low risk of bias compared to the rest. The e-leprosy framework was being used along with applications based on smartphones and artificial intelligence Digital health technology was found to be practical, accessible and effective in leprosy control programmes. Studies reported favourable findings regarding the use of digital health technology in services related to leprosy patients.

The burden of physical disability among patients with newly detected leprosy in Yunnan, China, 1990-2020: A population-based, cross-sectional survey.

BackgroundPhysical disability is the main complication of leprosy. Although understanding the leprosy rate, prevalence, spatiotemporal distribution, and physical nerve characteristic trends is crucial for the implementation of leprosy control programs and identification of remaining challenges, these data are still unclear. We assessed physical disability trends among newly detected leprosy cases over the past 31 years in 129 counties and territories in Yunnan, China.Methodology/Principal findingsWe analyzed the data of newly detected leprosy cases from the Leprosy Management Information System in Yunnan, China, from 1990–2020. All available data related to physical disability were analyzed, including demographic characteristics (sex, age, ethnicity, education level); clinical characteristics (diagnosis duration, detection mode, contact history, leprosy reaction, skin lesions, nerve lesions, disability classification); World Health Organization (WHO) leprosy physical disability indicators; and nerve and eyes, hands and feet (EHF) involvement. A total of 10758 newly diagnosed leprosy cases were identified, and 7328 (65.60%), 1179 (10.55%) and 2251 (20.15%) were associated with grade 0, 1, and 2 disability (G0D, G1D, and G2D), respectively. Male sex, older age, Han ethnicity, urban employment, a longer diagnosis duration, a contact history, greater nerve involvement, and tuberculoid-related forms of leprosy were associated with increased prevalence rates of physical disability. The rates of physical disability in newly detected leprosy cases per 1 million population decreased from 5.41, 2.83, and 8.24 in 1990 to 0.29, 0.25, and 0.54 per 1 million population in 2020, with decreases of 94.64%, 91.17%, and 93.44% in G2D, G1D and total physical disability (G1D + G2D) rates, respectively. In the same period, the proportions of G2D, G1D and total physical disability decreased from 28.02%, 14.65%, and 42.67% in 1990 to 10.08%, 11.76%, and 21.85% in 2020, with decreases of 64.03%, 19.73%, and 48.79%, respectively. Nerve thickening was more common than nerve tenderness, and claw hand, plantar insensitivity, and lagophthalmos were the most frequently reported EHF-related disabilities.ConclusionsDespite general progress in reducing the prevalence of leprosy-related physical disability, the proportion of physical disability among leprosy disease remains high, especially in specific counties. This implies that leprosy cases are being detected at a later stage and that transmission in the community still exists. Further efforts focusing on early detection are crucial for leprosy control and the elimination of the disease burden.

Social Determinants and Leprosy in High Endemic Regions of Myanmar: an Ecological Study between 2016 and 2019

Leprosy has been a public health problem in Myanmar for many centuries. This study aims to explore the situation of leprosy and the association between leprosy and social determinants at the township level in seven endemic regions in Myanmar. The objectives of the study are to (i) describe the incidence and severity of leprosy and the disability due to leprosy in Myanmar between 2016 and 2019, and (ii) determine the correlation between leprosy incidence and social determinants in Myanmar in 2019. We used annual surveillance data of leprosy cases between 2016 and 2019 from the National Leprosy Control Program, Myanmar, and social determinant variables from the 2019 General Administration Department Census Report of Myanmar. An ecological cross-sectional study was conducted. Univariable and multivariable analyses applying zero-inflated negative binomial regression models were used. A geographic information system mapping was used to visualize leprosy cases, disease severity, and disability due to leprosy between 2016 and 2019. The number of all leprosy indicators changing pattern was seen obvious between regions. The eastern region showed relatively an increase in detection of new cases in 2019 compared with years 2017 and 2018. The increase in the detection of multibacillary leprosy cases was also observed in the eastern region during this period. Yet, the detection of Grade-II disability cases across regions remained relatively stable throughout study years. The number of tuberculosis cases per 1,000 population was significantly correlated with leprosy incidence at the township level (risk ratio 1.27, 95% confidence interval 1.04–1.55). These findings highlight the importance of enhancing active case finding campaigns in high-endemic regions, especially the eastern states of Myanmar. Integration of leprosy and tuberculosis case-finding programmes is likely to help leverage resources and maximize efforts to cope with leprosy problems in Myanmar.

Delayed detection of leprosy cases: A systematic review of healthcare-related factors.

In new leprosy cases, grade 2 disability (G2D) is still a public health burden worldwide. It is often associated with the delayed leprosy diagnoses that healthcare systems should play a crucial role in preventing. The aim of this systematic review was to identify healthcare factors related to delays in case detection in leprosy. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) was used as a guideline in this research. The study protocol was registered in the PROSPERO (International Prospective Register of Systematic Reviews) with reference code CRD42020189274. Data was collected from five electronic databases: Embase, Medline All Ovid, Web of Science, Cochrane CENTRAL, and the WHO Global Health Library. After applying the selection criteria for original empirical studies, and after removing duplicates, we included 20 papers from 4313 records. They had been conducted in ten countries and published between January 1, 2000, and January 31, 2021. We identified three categories of healthcare factors related to delayed case. 1) Structural factors, such as i) financial and logistic issues, and geographical circumstances (which we classified as barriers); ii) Health service organization and management including the level of decentralization (classified as facilitators). 2) Health service factors, such as problems or shortages involving referral centers, healthcare personnel, and case-detection methods. 3) Intermediate factors, such as misdiagnosis, higher numbers of consultations before diagnosis, and inappropriate healthcare services visited by people with leprosy. Delays in leprosy case detection are due mainly to misdiagnosis. It is crucial to improve the training and capacity of healthcare staff. To avoid misdiagnosis and reduce detection delays, national leprosy control programs should ensure the sustainability of leprosy control within integrated health services.

Epidemiological trends of leprosy and case detection delay in East Hararghe Zone, Ethiopia: A baseline survey

Objectives Leprosy is a chronic infectious disease caused by Mycobacterium leprae and one of the world’s most neglected tropical diseases. The post-exposure prophylaxis for leprosy study (PEP4LEP) compares two integrated skin-screening approaches combined with single dose rifampicin administration to contacts of leprosy patients. The aim of this baseline survey was to describe the epidemiological trends of leprosy and estimate case detection delay in the Ethiopian study districts before the start of the intervention. Methods The study was conducted in three districts of East Hararghe zone, Oromia Region, Ethiopia. We applied descriptive retrospective study design to describe epidemiological trends of leprosy between 2010 and 2019. Fifty patients diagnosed in the six months prior to their inclusion in the study were interviewed to establish the case detection delay at baseline. The healthcare delivery system and National Leprosy Control Program are also described. Results Trends in the number of new leprosy patients detected decreased slightly over the past ten years, although the number of new child cases increased overall, suggesting ongoing transmission. The mean case detection delay was 22.4 months (95% CI: 18.6–26.3), while the median was 19.5 months. The mean patient and health system delay were 19.6 months (95% CI: 15.8–23.4) and 2.6 months (95% CI: 1.5–3.6), respectively. Conclusion Considerable leprosy case detection delays were found in the PEP4LEP study districts in Ethiopia. Efforts to reduce delay and interrupt the transmission should focus on integrating prevention and active case finding, contact tracing and providing post-exposure prophylaxis to contacts of leprosy patients.

Leprosy indicators and diagnosis delay in Mogovolas, Meconta and Murrupula district of Nampula Province, Mozambique: A baseline survey

Objectives Leprosy is a chronic infectious disease caused by Mycobacterium leprae. The PEP4LEP project will compare two integrated skin-screening interventions combined with the distribution of a single dose of rifampicin as post exposure prophylaxis (SDR-PEP) for contacts of leprosy patients. To implement the study in Mozambique, it was necessary to assess recent epidemiological indicators of leprosy and to estimate case detection delay as a main outcome indicator at baseline. Methods This was a descriptive study to establish the trend of epidemiological indicators of leprosy in the Nampula province districts Murrupula, Meconta and Mogovolas in Mozambique, between 2015 and 2019; and to calculate the average delay to diagnose leprosy cases in these districts. The National Leprosy Control Programme was also described. For the estimation of the case detection delay, 81 recently diagnosed patients were interviewed. Results There were 939 new leprosy cases detected in the three districts from 2015 to 2019, with a high proportion of disability (17.0%). The mean diagnosis delay was 26.6 months (95% CI: 18.4–34.7), while the median was 17.0 months. Multibacillary cases had an average delay of 27.9 months (95% CI: 18.6–37.1), while those with grade 2 disability had an average delay of 47.8 months (95% CI: 15.4–80.2). Conclusion The long case detection delay and high grade 2 disability rates indicate that there is a need for active case finding and chemoprophylaxis with SDR-PEP to help interrupt the chain of Mycobacterium leprae transmission in Nampula province.

Treatment outcome of pediatric tuberculosis in eastern Ethiopia.

BackgroundChildren are more vulnerable to developing active Mycobacterium tuberculosis infection which causes significant morbidity and mortality. However, the contribution of childhood tuberculosis and its treatment outcomes have not been well documented, and no research has been conducted in eastern Ethiopia.ObjectiveThis study aimed to assess the treatment outcome and its predictors of pediatric tuberculosis in eastern Ethiopia from September 1, 2017 to January 30, 2018.MethodsA retrospective study was conducted in eight selected hospitals in eastern Ethiopia. Data on 2002 children with tuberculosis was extracted by using the standard checklist of the national tuberculosis treatment format. Treatment outcomes were determined according to the standard definitions of the National Tuberculosis and Leprosy Control Programme. Data were entered into Epi Data software version 3.1 and exported to Statistical Package for Social Science (SPSS) version 20 for analysis. Bivariable and multivariable regression analyses were carried out to examine the associations between dependent and independent variables. A P-value of <0.05 was considered statistically significant.ResultThe overall successful treatment rate was 1,774 (88.6%) [95% confidence interval (CI): (80.59–97.40)]. A total of 125 (6.2%), 1,648 (82.3%), 59 (2.9%), and 19 (0.9%) children with tuberculosis (TB) were cured, completed, defaulted, and died, respectively. A high number of defaulters and deaths were reported in the age group <10 years. More children with smear-positive pulmonary TB (74.4%) were cured, while smear-negative tuberculosis had higher treatment completion rates. Being male in sex (adjusted odds ratio (AOR): 0.71, 95% CI: 0.53, 0.96) and those with human immunodeficiency virus (HIV) positive sero status (AOR: 0.51, 95% CI: 0.29, 0.90) had a lower chance of a successful treatment outcome.ConclusionIn this study, thee treatment success rate was higher than the recent World Health Organization report. Those males and HIV seropositive status were less likely to have a successful treatment outcome. Therefore, efforts should be made by each health institution in eastern Ethiopia by giving emphasis on male and HIV-positive individuals.

Association between clinical forms of leprosy and contacts with the vaccination state with BCG in five endemic municipalities in the Brazilian Amazon

Introduction: The World Health Organization (WHO) strategy for leprosy control from 2021 to 2030 focuses on interrupting transmission, reducing autochthonous cases to zero, and using a safe and effective vaccine and chemoprophylaxis. In 2020, 127,396 new cases were registered in the world, 19,195 new cases in the Americas, and, of these, 17,979 cases in Brazil, about 93.66% of the total in the Americas. Brazil is classified as a country with a high burden of the disease, occupying the 2nd place in the world, behind only India (WHO, 2020). Análise do período de 2010-2015 em publicação recente9, apresenta as seguintes cidades no estado do Pará nas quais se observou maiores taxas de incidência (detecção): Marituba, Belém, Marabá, Parauapebas e Altamira [9]. Material and method: This is an analytical retrospective study carried out in a database - Epi-Info resulting from records of Surveillance and Seroprevalence actions in five endemic municipalities for leprosy located in the Southeast and West of Pará. The following variables were analyzed: age, sex, Clinical Classification, vaccination status with BCG, and the result of the search for IgM antibodies against PGL-1 of Mycobacterium leprae by the “In house” ELISA technique. Results: We evaluated 1551 records examined in the laboratory from 2014 to 2016, which were classified into 123 Multibacillary -MB patients (123/1551 = 7.93%); 71 Paucibacillary-PB patients (71/1551 = 4.57%); 451 Intradomicilliary Consanguineous Contacts - CCOSI (451/1551 = 29.07%) and 906 Non Consanguineous Contacts - CNCOS (906/1551 = 58.41%). 57 MB patients (13.47%), 13 PB patients (3.07%), 133 CCOSI (31.44%) and 220 CNCOS (52.00%) were positive for PGL-1. The correlation of the Classification with the vaccination status showed 57 MB patients without any BCG (57/125 = 45.6%) and only 3 patients with two doses of BCG (3/125 = 2.4%); 17 PB patients without any dose of BCG (17/69 = 24.63%); 80 CCOSI without any BCG (80/455 = 17.58%) and 171 CNCOS (171/906 = 18.87%). The odds ratio (OR) in the analysis between unvaccinated MB patients compared to CCOSI was statistically significant (OR = 14.25; p ˂ 0.0001). The study shows the importance of using the BCG vaccine in healthy contacts of patients with leprosy, as it shows the probability of unvaccinated individuals being 14.25 times more likely to become ill with Multibacillary forms compared to CCOSI. In addition, the BCG vaccine has been in use for 80 years and is the only vaccine that we can use in leprosy control programs. Conclusion: Although the leprosy epidemiological data analyzed recently (2010 - 2015) show a downward trend in the main indicators in Pará, such as the detection of new cases and prevalence, the endemic municipalities are still classified as hyperendemic for the population under 15 years of age and This proves that Surveillance is essential, as well as BCG vaccination according to the Ministry of Health Standards.

LEPROSY CONTROL PROGRAM IN VIET NAM

Abstract: The Vietnam National Leprosy Control Program (NLCP) was launched in 1982 and Multidrug Therapy (MDT) was implemented one year later (1983). Since then, remarkable progress has been achieved in reducing the disease burden. Vietnam reached the goal of leprosy elimination with the prevalence rate (PR) of less than 1 case/10, 000 population at National level in 1995 and at District level in the year 2000.&#x0D; After reaching the goal of leprosy elimination as a public health problem, in 2003 the NLCP set up the new strategy with 4 Vietnamese criteria for elimination at Provincial level. The Leprosy network was improved, and activities of the program were strengthened from Central to grassroot level. As a result, all provinces/cities gained the Vietnamese criteria of leprosy elimination in 2012.&#x0D; Although the prevalence rate has come down, new cases are being continuously detected yearly in some regions of the country. Based on the new situation of the disease, a new strategy has been developed in order to eliminate leprosy at the district level.
