(1) Background: The global burden of leprosy is not shared equally; with the majority of cases being diagnosed in Brazil, India, and Indonesia. Understanding the methods of active case detection (ACD) used in high and low endemic regions is vital for the development of future screening programs. (2) Methods: A systematic search of three databases, PubMed, Embase and Web of Science, was conducted for English language papers, published since the year 2000, which discussed the use of active case detection methods for leprosy screening. The paper utilised the Integrated Screening Action Model (I-SAM) as a tool for the analysis of these methods. (3) Results: 23 papers were identified from 11 different countries. The papers identified 6 different methods of active case detection: Household contact/social contact identification; door-to-door case detection; screening questionnaire distribution; rapid village surveys; school-based screening; and prison-based screening. 15 were located in high endemic regions and 8 of these were located in low endemic regions. (4) Conclusions: For selecting the appropriate methods of active case finding, the leprosy endemicity must be taken into consideration. The findings contribute to policy decision making allowing for more successful future leprosy case detection programs to be designed, ultimately reducing the global burden of the disease, and achieving the WHO\'s aim of zero leprosy.

Leprosy is still found mainly in lower-middle-income countries. Breaking the chain of leprosy transmission requires various ways, especially by increasing knowledge of leprosy prevention through health education. Although several studies have mentioned the effectiveness of health education, there is still uncertainty about the best method to use. Therefore, the review question should be answered: what forms of health education have been developed about Leprosy in the community? This review study complies with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) version 2020. The search for relevant literature involved PubMed, ScienceDirect, ERIC, Cochrane, and ProQuest databases for the studies published in the 2000 to 2023 period with the inclusion criteria such as increasing knowledge, changing attitudes and behavior, and increasing positive stigma. The quality of the study was assessed using the Critical Appraisal Skills Program, and the Risk of Bias using the Cochrane RoB tool. Overall search on databases resulted in a total of 184,681 articles. Only six studies were eligible to be included in this review. Various educational methods were used in the eligible studies, including MH Mobile, the myth or truth on Leprosy game, posters, leaflets, community meetings, tele-education the web, discussion lists, chats, activity diaries, iconographic 3D videos, classes on video streaming, video conference, case simulation, lecture, and the contact intervention (education, testimonies (direct contact), videos, and comics). All of the methods used had the potential to improve knowledge, attitude, and practice and reduce negative stigma regarding Leprosy. There is no method of health education superior to another on Leprosy prevention.

Leprosy is an infectious disease that remains a public health concern. It is caused by acid-fast Bacillus leprae, which primarily affects the skin and peripheral nerves, potentially leading to long-term disability and stigma. However, current and previous efforts have focused on developing better diagnostic and therapeutic interventions for leprosy, and its prevention needs to be addressed. In this review, we organize the currently published papers and provide updates on the global epidemiology, diagnosis, treatment, and prevention of leprosy. Several online databases, including MEDLINE (National Library of Medicine, Bethesda, MD), PubMed, EMBASE, Web of Science, and Google Scholar, were searched to collect relevant published papers. As a public health issue, the World Health Organization set the goal of leprosy elimination with a prevalence of <1 case per 10,000 people, which was achieved in 2000 and in most countries by 2010, mainly owing to the treatment of leprosy using drugs starting in 1980 and no-cost access for patients since 1995. Although diagnostic and therapeutic techniques have improved, the new occurrence of leprosy remains a critical global disease burden. With continuous technological improvements in diagnosing and treating leprosy, obtaining more relevant healthcare knowledge and preventing leprosy disability are crucial.

OBJECTIVE: to identify and synthesize, from the literature, the impacts of physical disability caused by leprosy on the quality of life of individuals receiving care within the Health Care Network.
METHODS: this is a scoping review conducted following the JBI recommendations. The databases used in the search included the Medical Literature Analysis and Retrieval System Online, Cochrane Library, Web of Science, Lilacs, Cumulative Index to Nursing and Allied Health Literature, Scopus, Embase, Leprosy Information Services, and Google Scholar.
RESULTS: 1690 documents were identified, of which 36 were included in the review. Physical disability caused by leprosy affects the quality of life in the areas of daily activities, socioeconomic aspects, psychological well-being, pain, and overall well-being.
CONCLUSIONS: we identified the impairments caused by physical disability in the quality of life, highlighting the need for prevention, promotion, and rehabilitation actions, such as screening, case management, and health education.

ΟBJECTIVES: Although Buruli ulcer, tuberculosis, and leprosy are the three most common mycobacterial diseases, One Health dimensions of these infections remain poorly understood. This narrative review aims at exploring the scientific literature with respect to the presence of animal reservoir(s) and other environmental sources for the pathogens of these infections, their role in transmission to humans and the research on/practical implementation of One Health relevant control efforts.
METHODS: The literature review was conducted using the online databases PubMed, Scopus, ProQuest and Google Scholar, reviewing articles that were written in English in the last 15 years. Grey literature, published by intergovernmental agencies, was also reviewed.
RESULTS: For the pathogen of Buruli ulcer, evidence suggests possums as a possible animal reservoir and thus having an active role in disease transmission to humans. Cattle and some wildlife species are deemed as established animal reservoirs for tuberculosis pathogens, with a non-negligible proportion of infections in humans being of zoonotic origin. Armadillos constitute an established animal reservoir for leprosy pathogens with the transmission of the disease from armadillos to humans being deemed possible. Lentic environments, soil and other aquatic sources may represent further abiotic reservoirs for viable Buruli ulcer and leprosy pathogens infecting humans. Ongoing investigation and implementation of public health measures, targeting (sapro)zoonotic transmission can be found in all three diseases.
CONCLUSIONS: Buruli ulcer, tuberculosis and leprosy exhibit important yet still poorly understood One Health aspects. Despite the microbiological affinity of the respective causative mycobacteria, considerable differences in their animal reservoirs, potential environmental sources and modes of zoonotic transmission are being observed. Whether these differences reflect actual variations between these diseases or rather knowledge gaps remains unclear. For improved disease control, further investigation of zoonotic aspects of all three diseases and formulation of One Health relevant interventions is urgently needed.

BACKGROUND: Leprosy is a chronic infectious disease caused by Mycobacterium leprae (M. leprae) that is responsible for deformities and irreversible peripheral nerve damage and has a broad spectrum of clinical and serological manifestations. Leprosy primarily affects the peripheral nerves and rarely presents with central nervous system involvement. Diagnosing leprosy can still be difficult in some cases, especially when the infection involves uncommon clinical manifestations and extracutaneous sites. Delayed diagnosis and treatment of leprosy may lead to irreversible damage and death.
METHODS: We report a case of a 30-year-old female presenting with \"repeated high fever with symptoms of headache for 14 days\". On the day of admission, physical signs of lost eyebrows and scattered red induration patches all over her body were observed. The patient\'s diagnosis was based on the clinical characteristics using a combination of metagenomic next-generation sequencing (mNGS) of cerebrospinal fluid (CSF) and slit-skin smear. After confirming Listeria meningitis and multibacillary leprosy with erythema nodosum leprosum (ENL), a type 2 reaction, she was treated with ampicillin sodium, dapsone, rifampicin, clofazimine, methylprednisolone, and thalidomide. At the 1-year follow-up, the frequency and severity of headaches have significantly decreased and a good clinical response with improved skin lesions was found.
CONCLUSIONS: This case highlights the importance of considering leprosy, which is a rare and underrecognized disease, in the differential diagnosis of skin rashes with rheumatic manifestations, even in areas where the disease is not endemic, and physicians should be alerted about the possibility of central nervous system infections. In addition, mNGS can be used as a complementary diagnostic tool to traditional diagnostic methods to enhance the diagnostic accuracy of leprosy.

The current meta-analysis aims to explore the potential correlation between natural resistance-associated macrophage protein 1 (NRAMP1) (3\'-Untranslated region [3\'-UTR]) and nucleotide-binding oligomerization domain-2 (NOD2 [rs8057341]) gene polymorphisms and their association with leprosy susceptibility in both Asian and Caucasian populations. Datas were retrieved from case control studies with NOD 2 and NRAMP 1 gene polymorphism associated with leprosy disease. Leprosy emerges as a particularly distinctive ailment among women on a global scale. The NRAMP1 (3\'-UTR) and NOD2 (rs8057341) genetic variations play a crucial role in the progression of leprosy. A systematic review of relevant case-control studies was conducted across several databases, including ScienceDirect, PubMed, Google Scholar, and Embase. Utilizing MetaGenyo and Review Manager 5.4 Version, statistical analyses were carried out. Nine case-control studies totaling 3281 controls and 3062 leprosy patients are included in the research, with the objective of examining the potential association between NRAMP1 (3\'-UTR) and NOD2 (rs8057341) gene polymorphisms and leprosy risk. The review methodology was registered in PROSPERO (ID520883). The findings reveal a robust association between NRAMP1 (3\'-UTR) and NOD2 (rs8057341) gene polymorphisms and leprosy risk across various genetic models. Although the funnel plot analysis did not identify publication bias, bolstering these findings and elucidating potential gene-gene and gene-environment interactions require further comprehensive epidemiological research. This study identified a strong correlation between polymorphisms in the NOD2 (rs8057341) genes and susceptibility to leprosy across two genetic models. Further comprehensive epidemiological investigations are warranted to validate these findings and explore potential interactions between these genes and environmental factors.

Mycobacterium Indicus Pranii (MIP) vaccine is a killed vaccine developed in India for leprosy with immunotherapeutic as well as immunoprophylactic effects. MIP, earlier known as Mycobacterium welchii, is a rapidly growing non-pathogenic mycobacterium. The novelty of this bacterium is due to its translational application as an immunotherapeutic agent. When administered intradermally, the vaccine induces cell-mediated immunity in the host towards Mycobacterium leprae. It leads to faster clinical and histopathological improvement, rapid bacillary clearance, and also lepromin conversion in anergic leprosy patients. The beneficial role of the MIP vaccine in augmenting the therapeutic efficacy of Multidrug Therapy (MDT), particularly in highly bacillated leprosy patients, is well documented in various studies from India. The role of the vaccine in reactional states is controversial, with varied results in different studies. Overall, it is found to decrease the frequency of type 2 lepra reactions and is useful in recalcitrant erythema nodosum leprosum. Even though there may be an increased likelihood of type 1 reactions, no additional nerve function impairment is attributed to the vaccine in various studies. In household contacts of leprosy who are administered MIP, it is noted to confer protection from disease lasting up to 10 years. It may prove to be a cost-effective strategy in national leprosy programmes. Apart from local injection site reactions, the vaccine is relatively safe, but it is not recommended in pregnancy and lactation. This article provides an overview of the MIP vaccine\'s clinical application in the context of leprosy spanning over 40 years. It also considers the vaccine\'s possible future applications in the management of disease-related complications and achieving the long-term goal of zero leprosy.

OBJECTIVE: to identify Primary Health Care professionals\' practice in the face of leprosy.
METHODS: a scoping review, carried out between November 2022 and January 2023, conducted according to the methodological structure proposed by JBI and checklist Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews in six databases and additional literature.
RESULTS: the sample consisted of 11 articles, published between 2008 and 2022. The findings were synthesized into three categories: Early diagnosis and timely treatment; Physical disability prevention; and Household and social contact surveillance.
CONCLUSIONS: there is a need to align the practices carried out with those recommended by the Brazilian National Program for Leprosy Control and Elimination, as some were not identified in studies, which implies losses to qualified assistance directed to patient demands, with a view to control and elimination of leprosy.

Until now, leprosy remains a problem and challenge in the world because it can cause disability and morbidity in affected individuals, including problems due to the emergence of type 2 lepra reaction or erythema nodosum leprosum (ENL). The clinical picture of ENL can appear in an atypical and severe form, called ENL necroticans (ENN), which becomes a problem in diagnosis and therapy. We report a 17-year-old female with lepromatous leprosy and ENN who received therapy in the form of a combination of steroids and methotrexate. Four months after consuming this therapy, the ulcers on the patient\'s body improved, leaving atrophic and hypertrophic scars. ENN\'s unusual clinical presentation poses diagnostic difficulties in that its appearance does not follow the typical patterns, making it challenging to identify correctly. Furthermore, managing cases of ENN may necessitate supplementary treatment beyond steroids alone.
