ABSTRACT

BACKGROUND: Kerala has a history of achievements in health through acting on the distal social determinants, but certain communities like tribals were pushed back from the stream of social development and health achievements. Subsequently, the lifestyle and the poor living conditions of tribes make them more prone to several diseases including skin diseases. However, neither the burden nor the situation of the same in the tribal population in several parts including Kerala is seldom assessed. MAIN BODY: The lack of awareness about the symptoms, complications, and management options as a part of the social backwardness has led to the concentration of certain diseases like Leprosy among the tribal community. In addition, the tribal population is under the threat of infectious diseases of public health significance like Leishmaniasis (CL). The tribal population owing to ignorance neglects the skin lesions or uses their local remedies. Tribes might have been using many local remedies for their issues, but the emerging skin diseases may not be amenable to local remedies and often impose significant public health concerns. Developing and maintaining an effectively functioning health system in these difficult-to-reach terrains is also a challenge. The pattern of skin diseases among tribals residing in environmentally sensitive localities is an indicator for the need for more social, economic and geospatial inclusion. Skin lesions of the tribal population should be kept under active surveillance activities through the integrated health information platform (IHIP) and it should follow a vigilant public health response if there are clusterings. A dedicated evidence-based system should be developed to diagnose and treat skin diseases of tribal people residing away from the availability of specialist care using local resources and community-level workers. CONCLUSION: The rampant skin diseases among tribals are the product of their unacceptable socio-economic status and living conditions. It could only improve through interventions focusing on social determinants of health. Improvements in the living conditions of tribals are sustainable long-term solutions, but such solutions should be coupled with medium-term and short-term strategies.

ABSTRACT

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.

ABSTRACT

INTRODUCTION: Leprosy and lymphatic filariasis (LF) are among the most disabling neglected tropical diseases (NTDs) that affect the citizens of Mozambique, especially in the Northern provinces. The irreversible impairments caused by these NTDs often lead to psychosocial consequences, including poor mental wellbeing, stigma and reduced social participation. Limited data on these consequences are available for Mozambique, which are urgently needed to better understand the true disease burden and support advocacy for scaling up interventions. METHODS: A cross-sectional mixed-methods study was conducted. Mental distress was assessed with the Self Reporting Questionnaire (SRQ-20), participation restriction was assessed with the Participation Scale Short (PSS) and perceived stigma was assessed with the Explanatory Model Interview Catalogue affected persons stigma scale (EMIC-AP). Additionally, semi-structured interviews were conducted with persons affected by leprosy or LF. RESULTS: In total, 127 persons affected by leprosy and 184 persons affected by LF were included in the quantitative portion of the study. For the qualitative portion, eight semi-structured interviews were conducted. In both disease groups, mental distress was found in 70% of participants. Moreover, 80% of persons affected by leprosy and 90% of persons affected by LF perceived stigma. Moderate to extreme participation restriction was found in approximately 43% of persons affected by leprosy and in 26% of the persons affected by LF. Persons affected by leprosy and LF felt excluded from society and experienced financial problems. More severe disabilities were associated with more severe outcomes for mental wellbeing, participation restriction and stigma. By contrast, participation in a self-care group was suggested to have a positive impact on these outcomes. CONCLUSION: The findings provide evidence that persons affected by leprosy and LF must not only confront physical impairments but also experience significant disability in the psychosocial domain, including mental distress, participation restriction and stigma. These challenges must be urgently addressed by NTD programmes to promote the inclusion and wellbeing of persons affected by NTDs.

ABSTRACT

Leprosy is a chronic infectious disease that has a slow evolution and is characterized by dermatoneurological involvement. The health challenges surrounding this disease are closely related to the stigma that results from the physical disabilities it causes. This is due to its high rate of late diagnosis and the peculiar deformities that occur in its advanced stage. Evaluate the clinical and epidemiological aspects of patients with plantar lesions who were treated for leprosy in a dermatology referral unit. This is a cross-sectional exploratory field study that was conducted at the Reference Center in Tropical Dermatology and Venereology Alfredo da Matta (FUHAM), in Manaus, Amazonas, Brazil. We evaluated 36 patients with disabilities as a result of leprosy and who had plantar lesions. The most common ulcer site was the medial region of the plantar surface, which presented dryness and maceration with yellowish seropurulent exudate, fibrinous tissue and grade 2 depth. The study made it possible to observe the evolution of plantar ulcers resulting from the disease process, then evaluate them and discuss recommendations regarding the treatment and prevention of this type of physical disability.

ABSTRACT

OBJECTIVE: This study aims to develop and validate predictive models that assess the risk of leprosy development among contacts, contributing to an enhanced understanding of disease occurrence in this population. METHODS: A cohort of 600 contacts of people with leprosy treated at the National Reference Center for Leprosy and Health Dermatology at the Federal University of Uberlândia (CREDESH/HC-UFU) was followed up between 2002 and 2022. The database was divided into two parts: two-third to construct the disease risk score and one-third to validate this score. Multivariate logistic regression models were used to construct the disease score. RESULTS: Of the four models constructed, model 3, which included the variables anti-phenolic glycolipid I immunoglobulin M positive, absence of Bacillus Calmette-Guérin vaccine scar and age ≥60 years, was considered the best for identifying a higher risk of illness, with a specificity of 89.2%, a positive predictive value of 60% and an accuracy of 78%. CONCLUSIONS: Risk prediction models can contribute to the management of leprosy contacts and the systematisation of contact surveillance protocols.

ABSTRACT

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. CONCLUSION: 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.

ABSTRACT

OBJECTIVE: To analyze the temporal trend of healthcare services quality indicators to reduce leprosy in Brazil, over a 20-year period. METHODS: This is an epidemiological study with a temporal trend, whose data were extracted from the Notifiable Diseases Information System. Indicators were constructed from the Ministry of Health Technical-Operational Manual that presents the Guidelines for Surveillance, Care and Elimination of Leprosy as a Public Health Problem. For trend analysis of the selected indicators, the Prais-Winsten model was used and the Average Annual Growth Rate (AAGR) was also calculated. RESULTS: In the 20-year time series investigated here, 732,959 cases of leprosy were reported in Brazil. The trend was stationary for: new leprosy cases cure rate (ß=-0.000; p=0.196; AAGR=-0.2), new leprosy cases drop out rate (ß=-0.001; p=0.147; AAGR=-0.4), new leprosy cases contact tracing rate (ß=-0.001; p=0.112; AAGR=1.6), new cases of leprosy with degree physical disability assessment rate among new cases (ß=-0.000; p=0.196; AAGR=-0.2) and cases cured in the year with the degree of physical disability assessed (ß=0.002; p=0.265; AAGR=0.5); while the indicator of recurrence rate among cases reported in the year (ß=0.019; p<0.001; AAGR=0.5) showed an increasing trend. CONCLUSION: Based on the evaluation of indicators to assess the quality of healthcare services to reduce leprosy, it was evident that Brazil has major challenges for its full implementation, with improvements being necessary in the quality of care service offered to the population.

ABSTRACT

BACKGROUND: Although leprosy, a neglected tropical disease, has been eliminated (<1 case per 10 000 population) in South Africa (SA) since 1926, according to the World Health Organization, new cases continue to be reported. The management of leprosy poses several challenges, including patient adherence, education and insufficient training of healthcare practitioners. OBJECTIVES: To describe the biographical profile, clinical manifestations and treatment outcomes in patients with leprosy in KwaZulu-Natal Province. METHODS: This retrospective study aimed to analyse the clinical data of leprosy patients in SA from 2002 to 2022. Data collected included patient demographics, comorbidities, cutaneous and neurological manifestations of leprosy, complications, treatment and adverse reactions. Descriptive statistics were used to summarise the data. RESULTS: The study analysed the clinical data of 194 leprosy patients from 2002 to 2022. The majority of patients were male and middle aged, with a disproportionate representation of black South Africans. Regarding socioeconomic status, 80% were unemployed and 40% were social grant recipients. Most cases were clustered in urban centres and diagnosed at secondary care facilities, with 15% being HIV positive. The majority of patients (90%) were classified as having multibacillary leprosy. Common symptoms included upper respiratory tract involvement, hair loss and painful nerves, with the face and limbs being most frequently affected. Cutaneous morphology predominantly included plaques and hypopigmented patches, while neurological signs included ulnar nerve tenderness, muscle weakness and sensory deficits. Debilitating neurological complications were found in one-fifth of patients. Despite initiation of multidrug therapy in most patients, a significant proportion (27.3%) did not complete the full course of treatment, and treatment reactions were noted in 33.5% of patients. CONCLUSION: These findings emphasise the urgent need for enhanced patient and healthcare worker education, particularly in primary healthcare settings, to improve adherence to treatment, advocate for prophylactic measures and prevent new cases. Achieving leprosy-free status in SA requires the collaboration of many role-players to address these challenges and improve healthcare practices.

ABSTRACT

BACKGROUND: Leprosy, a neglected tropical disease, is reported in over 120 countries, with upwards of 200,000 new cases annually. This Cross-Sectional Cohort Study aimed to delineate the epidemiological profile of leprosy in a low-endemic area in southern Brazil, both before and after implementing an active search strategy. METHODS: The study examined two surveillance periods in Caçador, Santa Catarina, Brazil. The active search strategy was carried out through the application of the LSQ by the community health workers as a screening and detection tool for new cases of leprosy and this was compared with passive case detection. The first spanned from 2014 to 2020, and the second from January 2021 to August 2023. FINDINGS: 48 leprosy cases were reported throughout the study, 83.3 % of which were diagnosed as multibacillary. The first period had an average detection rate of 0.38 cases per 10,000 inhabitants, increasing to 1.19 cases per 10,000 inhabitants in the second period. Notably, there was a substantial shift in the degree of physical disability (GD), with more Grade 0 and Grade 1 disabilities observed post-active search. MAIN CONCLUSIONS: The study underscores the efficacy of active search strategies in early diagnosis, highlighting a 300 % increase in the annual average of diagnosed cases. This large number of detected cases demonstrates the high sensitivity of the LSQ. This approach significantly aids in uncovering hidden cases of leprosy, enhancing disease management and control in low-endemic areas indicating that the Ministry of Health should intensify leprosy control activities in these regions.

ABSTRACT

Parasitic co-infections are common in developing countries and can interfere with leprosy treatment, leading to an increased risk of inflammatory leprosy reactions. This study assessed serum immunoglobulin G (IgG) levels against Toxoplasma gondii and Visceral Leishmaniasis (VL) antigens in 270 leprosy patients from Brazilian states. Regarding the respective cut-offs, the prevalence of IgG seropositivity for T. gondii and VL were 21.05 % and 47.36 % in the leprosy-negative group, and 77.7 % and 52.6 % in the leprosy-positive group. Of the 270 leprosy patients, 158 (58.5 %) presented with inflammatory leprosy reactions. Of those, 72 (59.5 %) had neuritis, 35 (48.6 %) had reverse reactions, and 28 (38.9 %) had ENL in both Brazilian states. Leprosy patients with anti-Leishmania IgG seropositivity were 3.25 times more likely to develop neuritis (95 % C.I.: 1.187 - 9.154; p = 0.019). These findings are particularly relevant for clinical settings where both leprosy and parasitic diseases are prevalent and could provide essential guidance for detecting and addressing complications arising from parasitic co-infections in leprosy patients, thereby improving clinical management strategies.

ABSTRACT

BACKGROUND: Leprosy, or Hansen's disease, is a chronic infectious disease caused by Mycobacterium leprae. Togo achieved the target of eliminating leprosy as a public health problem in 2000 (less than 1 case/10 000 population). However, new cases of leprosy are still being reported. The aim of this study was to describe and map trends of leprosy cases notified in Togo from 2010 to 2022. METHODS: This was a descriptive cross-sectional study covering a thirteen-year period from January 1, 2010, to December 31, 2022. The data of the study were leprosy surveillance system's data collected monthly between 2010 and 2022. The estimated number of leprosy cases and the incidence rate of leprosy cases were reported for the whole population by region, by district, by calendar year (2010-2022) and by target sub-population (children under 15, women and people with disabilities). Observed case incidence rates were mapped by health district and by year. RESULTS: From January 1, 2010, to December 31, 2022, 1031 new cases of leprosy were diagnosed in Togo. The median age of subjects was 46 years (interquartile range: 33-60), with extremes from 4 to 96 years. Half the subjects were women (50.7%). Variations in the leprosy incidence rate by year show an increase between 2010 and 2022, from 0.7 cases /100,000 population to 1.1 /100,000 population respectively. From 2010 to 2022, the proportion of cases in children remained low, between 0 and 9%. The proportion of women fluctuated between 39.7% and 67.2% between 2010 and 2017, then stabilized at an average of 50% between 2018 and 2022. The proportion of multi-bacillary leprosy cases increased quasi-linearly between 2010 and 2022, from 70 to 96.6%. Mapping of leprosy cases showed that leprosy was notified in all Togo health districts during the study period, apart from the Lacs district, which reported no leprosy cases. CONCLUSION: Togo has achieved the elimination of leprosy as a public health problem. However, the increase in the number of new leprosy cases and the proportion of leprosy cases in children indicate that transmission of the disease is continuing and that supplementary measures are needed.

ABSTRACT

BACKGROUND: Skin neglected tropical diseases including leprosy and Buruli ulcer (BU)are a group of stigmatizing and disability-inducing conditions and these aspects of the diseases could lead to poor mental health. The study was designed to assess the burden of poor mental health and wellbeing among persons affected by leprosy or BU in Nigeria. METHODS: A community based cross-sectional study design was employed. The study involved persons affected by leprosy or BU. Ten local government areas with the highest number of notified leprosy or BU cases between 2014 and 2018 in southern Nigeria were purposively selected. Information were obtained using Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorders-7 (GAD-7), Warwick-Edinburgh Mental Well-being Scale (WEMWBS) and OSLO Social Support Scale. Outcome measure was poor mental health/wellbeing and was determined by proportion of respondents who had depressive symptoms, anxiety disorder and poor mental wellbeing. RESULTS: A total of 635 persons affected by leprosy or BU participated in the study. The mean age of respondents was 43.8±17.0 years and highest proportion, 22.2% were in age group, 40-49 years. Majority of respondents, 50.7% were males. A higher proportion of respondents, 89.9% had depressive symptoms, 79.4% had anxiety disorders and 66.1% had poor mental wellbeing. Majority, 57.2% had poor mental health/wellbeing. Among the respondents, there was a strong positive correlation between depression and anxiety scores, (r = 0.772, p<0.001). There was a weak negative correlation between depression score and WEMWBS score, (r = -0.457, p<0.001); anxiety score and WEMWBS score, (r = -0.483, p<0.001). Predictors of poor mental health/wellbeing included having no formal education, (AOR = 1.9, 95%CI: 1.1-3.3), being unemployed, (AOR = 3.4, 95%CI: 2.2-5.3), being affected by leprosy, (AOR = 0.2, 95%CI: 0.1-0.4) and having poor social support, (AOR = 6.6, 95%CI: 3.7-11.8). CONCLUSIONS: The burden of poor mental health/wellbeing among persons affected by leprosy or BU is very high. There is need to include mental health interventions in the management of persons affected with leprosy or BU. Equally important is finding a feasible, cost-effective and sustainable approach to delivering mental health care for persons affected with leprosy or BU at the community level. Improving educational status and social support of persons affected by leprosy or BU are essential. Engaging them in productive activities will be of essence.

ABSTRACT

INTRODUCTION: Neglected tropical diseases (NTDs) mainly affect underprivileged populations, potentially resulting in catastrophic health spending (CHS) and impoverishment from out-of-pocket (OOP) costs. This systematic review aimed to summarize the financial hardship caused by NTDs. METHODS: We searched PubMed, EMBASE, EconLit, OpenGrey, and EBSCO Open Dissertations, for articles reporting financial hardship caused by NTDs from database inception to January 1, 2023. We summarized the study findings and methodological characteristics. Meta-analyses were performed to pool the prevalence of CHS. Heterogeneity was evaluated using the I2 statistic. RESULTS: Ten out of 1,768 studies were included, assessing CHS (n = 10) and impoverishment (n = 1) among 2,761 patients with six NTDs (Buruli ulcer, chikungunya, dengue, visceral leishmaniasis, leprosy, and lymphatic filariasis). CHS was defined differently across studies. Prevalence of CHS due to OOP costs was relatively low among patients with leprosy (0.0-11.0%), dengue (12.5%), and lymphatic filariasis (0.0-23.0%), and relatively high among patients with Buruli ulcers (45.6%). Prevalence of CHS varied widely among patients with chikungunya (11.9-99.3%) and visceral leishmaniasis (24.6-91.8%). Meta-analysis showed that the pooled prevalence of CHS due to OOP costs of visceral leishmaniasis was 73% (95% CI; 65-80%, n = 2, I2 = 0.00%). Costs of visceral leishmaniasis impoverished 20-26% of the 61 households investigated, depending on the costs captured. The reported costs did not capture the financial burden hidden by the abandonment of seeking healthcare. CONCLUSION: NTDs lead to a substantial number of households facing financial hardship. However, financial hardship caused by NTDs was not comprehensively evaluated in the literature. To develop evidence-informed strategies to minimize the financial hardship caused by NTDs, studies should evaluate the factors contributing to financial hardship across household characteristics, disease stages, and treatment-seeking behaviors.

ABSTRACT

BACKGROUND: Post-exposure prophylaxis (PEP) using single-dose rifampicin reduces progression from infection with Mycobacterium leprae to leprosy disease. We compared effectiveness of different administration modalities, using a higher (20 mg/kg) dose of rifampicin-single double-dose rifampicin (SDDR)-PEP. METHODS: We did a cluster randomised study in 16 villages in Madagascar and 48 villages in Comoros. Villages were randomly assigned to four study arms and inhabitants were screened once a year for leprosy, for 4 consecutive years. All permanent residents (no age restriction) were eligible to participate and all identified patients with leprosy were treated with multidrug therapy (SDDR-PEP was provided to asymptomatic contacts aged ≥2 years). Arm 1 was the comparator arm, in which no PEP was provided. In arm 2, SDDR-PEP was provided to household contacts of patients with leprosy, whereas arm 3 extended SDDR-PEP to anyone living within 100 m. In arm 4, SDDR-PEP was offered to household contacts and to anyone living within 100 m and testing positive to anti-phenolic glycolipid-I. The main outcome was the incidence rate ratio (IRR) of leprosy between the comparator arm and each of the intervention arms. We also assessed the individual protective effect of SDDR-PEP and explored spatial associations. This trial is registered with ClinicalTrials.gov, NCT03662022, and is completed. FINDINGS: Between Jan 11, 2019, and Jan 16, 2023, we enrolled 109 436 individuals, of whom 95 762 had evaluable follow-up data. Our primary analysis showed a non-significant reduction in leprosy incidence in arm 2 (IRR 0·95), arm 3 (IRR 0·80), and arm 4 (IRR 0·58). After controlling for baseline prevalence, the reduction in arm 3 became stronger and significant (IRR 0·56, p=0·0030). At an individual level SDDR-PEP was also protective with an IRR of 0·55 (p=0·0050). Risk of leprosy was two to four times higher for those living within 75 m of an index patient at baseline. INTERPRETATION: SDDR-PEP appears to protect against leprosy but less than anticipated. Strong spatial associations were observed within 75 m of index patients. Targeted door-to-door screening around index patients complemented by a blanket SDDR-PEP approach will probably have a substantial effect on transmission.

ABSTRACT

Objective: To assess the effectiveness of a community-based tuberculosis and leprosy intervention in which village health teams and health workers conduct door-to-door tuberculosis screening, targeted screenings and contact tracing. Methods: We conducted a before-and-after implementation study in Uganda to assess the effectiveness of the community tuberculosis intervention by looking at reach, outputs, adoption and effectiveness of the intervention. Campaign 1 was conducted in March 2022 and campaign 2 in September 2022. We calculated percentages of targets achieved and compared case notification rates during the intervention with corresponding quarters in the previous year. We also assessed the leprosy screening. Findings: Over 5 days, campaign 1 screened 1 289 213 people (2.9% of the general population), of whom 179 144 (13.9%) fulfilled the presumptive tuberculosis criteria, and 4043 (2.3%) were diagnosed with bacteriologically-confirmed tuberculosis; 3710 (91.8%) individuals were linked to care. In campaign 2, 5 134 056 people (11.6% of the general population) were screened, detecting 428 444 (8.3%) presumptive tuberculosis patients and 8121 (1.9%) bacteriologically-confirmed tuberculosis patients; 5942 individuals (87.1%) were linked to care. The case notification rate increased from 48.1 to 59.5 per 100 000 population in campaign 1, with a case notification rate ratio of 1.24 (95% confidence interval, CI: 1.22-1.26). In campaign 2, the case notification rate increased from 45.0 to 71.6 per 100 000 population, with a case notification rate ratio of 1.59 (95% CI: 1.56-1.62). Of the 176 patients identified with leprosy, 137 (77.8%) initiated treatment. Conclusion: This community tuberculosis screening initiative is effective. However, continuous monitoring and adaptations are needed to overcome context-specific implementation challenges.
