Introduction:Leprosy is an infectious disease that can cause disability and physical sequelae when not treated early.Objective:To describe the epidemiological profile of leprosy in Bacabal, state of Maranhão. Methodology:This was a cross-sectional, retrospective, quantitative study on leprosy cases reported to the Notifiable Diseases Information System from 2008 to 2017. Data were analyzed using descriptive statistics. Results:A total of 1,309 cases were diagnosed, in the age group of 20 to 34 years (25.7%), male (60.2%), black race (39.8%), with elementary education (63.5%), and working in agriculture (32.3%). Primary care reported most cases (49.9%), and the majority of cases were from urban areas (78.7%). The predominant operational classification was multibacillary cases (76%), in the dimorphic clinical form (60.9%), from 2 to 5 multiple lesions (33%), without affected nerves (60.6%), and no physical disability (45.5%). Only 43% of cases underwent bacilloscopy, and multibacillary polychemotherapy with 12 doses was the most common treatment, accounting for 75.8% of diagnosed cases. Most cases were classified as new (77.8%) and were detected by spontaneous demand (38.5%), and more than Half were cured (80.3%).Conclusions: Leprosy is a disease endemic to the region and represents a public health challenge due to the high magnitude of cases. The importance of educational activities focusing on prevention through an active search for early diagnosis is highlighted to track cases and contacts in the community toreduce physical sequelae, which are crucial in combating the disease (AU).

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.

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.

To evaluate the prevalence of Mycobacterium leprae and Mycobacterium lepromatosis in road killed armadillos identified along Brazilian regions, samples of liver, spleen, muscle, ear, nose and tail were collected on highways from 78 animals. The armadillos were of four different species, Cabassous tatouay, Dasypus novemcinctus, Dasypus septemcinctus and Euphractus sexcinctus. After DNA extraction from two tissues, specific primers were used for the detection of each pathogen using SYBR green qualitative Real-Time PCR, and amplicons were sequenced. The species with the highest prevalence was D. novemcinctus, mainly in the Central-West, South, and Southeast regions of Brazil. We detected M. leprae DNA in 32 (41 %) of the 78 individuals and M. lepromatosis DNA was not identified in any of the examined samples. The zoonotic component of leprosy may play a role in the transmission of the disease in endemic areas in which environmental conditions and contact with reservoirs must be investigated.

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.

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.

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 21.05â¯% and 47.36â¯% in the leprosy-negative group, and 77.7â¯% and 52.6â¯% in the leprosy-positive group. Of the 270 leprosy patients, 158 (58.5â¯%) presented with inflammatory leprosy reactions. Of those, 72 (59.5â¯%) had neuritis, 35 (48.6â¯%) had reverse reactions, and 28 (38.9â¯%) had ENL in both Brazilian states. Leprosy patients with anti-Leishmania IgG seropositivity were 3.25 times more likely to develop neuritis (95â¯% 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.

BACKGROUND: The high levels of recent transmission of leprosy worldwide demonstrate the necessity of epidemiologic surveillance to understand and control its dissemination. Brazil remains the second in number of cases around the world, indicating active transmission of Mycobacterium leprae (M. leprae) in the population. At this moment, there is a consensus that the bacillus is transmitted by inter-human contact, however, different serologic, molecular, and histopathological approaches indicate the existence of non-human transmission sources. METHODS AND RESULTS: The qPCR assay was used to amplify the molecular targets 16S RNAr and RLEP, in samples of liver, spleen, and ear of wild animals belonging to Didelphimorphia and Rodentia orders, in highly endemic areas of Mato Grosso, Brazil. The RLEP repetitive sequence was positive in 202 (89.0%) samples, with 96 (42.3%) of these also being positive for the 16S gene. Regarding the collection sites, it was observed that the animals were found in areas profoundly deforested, close to urban areas. CONCLUSIONS: Our results suggest that wild animals can play an important role in the maintenance of M. leprae in endemic regions with major anthropic action in Brazil. Therefore, integrating human, animal, and environmental health care with the One Health initiative is highly efficient for the development of effective strategies to contain and control leprosy in Brazil.

BACKGROUND: To analyse the temporal trends and spatiotemporal distribution of leprosy relapse in Brazil from 2001 to 2021. METHODS: An ecological study with a temporal trend approach and space-time analysis of leprosy relapse in Brazil was carried out with data from the Notifiable Diseases Information System. RESULTS: A total of 31 334 patients who experienced leprosy relapse were identified. The number of recurrent cases tended to increase throughout the study period, and this increase was significant among females and in almost all age groups, except for those <15, 50-59 and ≥70 y. Several clusters of high- and low-risk patients were identified across all regions with a heterogeneous distribution. CONCLUSIONS: The burden of relapse showed an increasing trend in some groups and was distributed in all regions.
