Bioarchaeological investigation of individuals with suspected multibacillary leprosy from the mediaeval leprosarium of St Mary Magdalen, Winchester, Hampshire, UK.

Introduction. We have examined four burials from the St Mary Magdalen mediaeval leprosarium cemetery in Winchester, Hampshire, UK. One (Sk.8) was a male child, two (Sk.45 and Sk.52) were adolescent females and the fourth (Sk.512) was an adult male. The cemetery was in use between the 10th and 12th centuries. All showed skeletal lesions of leprosy. Additionally, one of the two females (Sk.45) had lesions suggestive of multi-cystic tuberculosis and the second (Sk.52) of leprogenic odontodysplasia (LO), a rare malformation of the roots of the permanent maxillary incisors.Gap statement. Relatively little is known of the manifestations of lepromatous leprosy (LL) in younger individuals from the archaeological record.Aims and Methodology. To address this, we have used ancient DNA testing and osteological examination of the individuals, supplemented with X-ray and microcomputed tomography (micro-CT) scan as necessary to assess the disease status.Results and Conclusions. The presence of Mycobacterium leprae DNA was confirmed in both females, and genotyping showed SNP type 3I-1 strains but with a clear genotypic variation. We could not confirm Mycobacterium tuberculosis complex DNA in the female individual SK.45. High levels of M. leprae DNA were found within the pulp cavities of four maxillary teeth from the male child (Sk.8) with LO, consistent with the theory that the replication of M. leprae in alveolar bone may interfere with root formation at key stages of development. We report our biomolecular findings in these individuals and review the evidence this site has contributed to our knowledge of mediaeval leprosy.

Cardiovascular events associated with thalidomide and prednisone in leprosy type 2 reaction.

BACKGROUND: Thalidomide is the drug of choice for the treatment of type 2 leprosy reactions and is often associated with corticosteroids. The use of these drugs in multiple myeloma is associated with the risk of cardiovascular events, but there have been few studies assessing this risk in leprosy patients. OBJECTIVE: To evaluate the occurrence of cardiovascular events in patients with multibacillary leprosy and their correlation with the use of thalidomide and prednisone. METHODS: Analytical cross-sectional study of all patients diagnosed with multibacillary leprosy treated at the Dermatology Service between 2012 and 2022, using electronic medical records. Thromboembolic vascular events, both arterial and venous, including acute myocardial infarction, were considered. The main independent variable was the concomitant use of thalidomide and prednisone during follow-up. RESULTS: A total of 89 patients were included, of which 19 used thalidomide and prednisone concomitantly. There were five cardiovascular events (26.3%), three of which of deep venous thrombosis. The combined use of medications was associated with the events (PR=6.46 [3.92 to 10.65]; p<0.01). STUDY LIMITATIONS: Small number of events, single-center retrospective study. CONCLUSION: The hypothesis of an association between cardiovascular events and the concomitant use of thalidomide and prednisone is supported, but more robust prospective studies are required for a better assessment.

Negligência no diagnóstico precoce de hanseníase na atenção primária: um relato de caso / Negligence in the early diagnosis of leprosy in primary care: a case report

A hanseníase é uma doença infecciosa, transmissível, de caráter crônico, com potencial grau de incapacidade, que ainda persiste como problema de saúde pública no Brasil. A demora e a falta de conhecimento técnico para realizar o diagnóstico resulta em inúmeros prejuízos aos pacientes acometidos pela doença, sendo que, a prevenção das incapacidades está relacionada diretamente com o diagnóstico precoce da doença. Com a finalidade de evitar a negligência diagnóstica e o desenvolvimento de incapacidades físicas, ressaltamos a importância do conhecimento técnico sobre o diagnóstico e o manejo da hanseníase por profissionais da saúde em qualquer nível de atenção à saúde ou especialidade.

Hansen is an infectious disease, transmissible, of a chronic nature, with serious potential for disability, which still persists as a public health problem in Brazil. The delay and the lack of technical knowledge to carry out the diagnosis with numerous prejudices to the patients affected by the disease, since the prevention of disabilities is directly related to the early diagnosis of the disease. In order to avoid diagnostic negligence and the development of physical disabilities, we highlight the importance of technical knowledge about the diagnosis and management of training by health professionals at any level of health care or special care.

Identificação de um paciente com hanseníase multibacilar por meio do teste sorológico (LID) em ações de busca ativa: um relato de caso / Identification of a patient with multibacillary leprosy using the serological test (LID) in active search actions: a case report

A hanseníase é uma doença crônica e infectocontagiosa causada pelo Mycobacterium leprae (M. leprae). Apresenta alta infectividade e baixa patogenicidade. O estudo teve como objetivo relatar a identificação de um paciente com hanseníase multibacilar através do teste sorológico (LID) em ação de busca ativa. Paciente do sexo masculino, 54 anos, residente em Governador Valadares, Minas Gerais, Brasil, proveniente da busca ativa do Núcleo de Pesquisa em Hansenologia (NuPqHans/UFJF-GV), apresentou teste sorológico positivo para proteínas recombinantes do bacilo (ML0405/ML2331). Encaminhado ao Centro de Referência de Doenças Endêmicas e Programas Especiais (CREDENPES), queixando-se de lesões na pele e nódulos pelo corpo, relatou histórico de traumas na cabeça, tonturas ocasionais, dormência nos pés e sangramento nasal. O paciente apresentou resultados de baciloscopia e biopsia positivos, concluindo o diagnóstico de hanseníase multibacilar, recebendo poliquimioterapia indicada. Após três meses de tratamento observou-se redução na área/diâmetro das lesões do abdômen, indicando a eficácia do tratamento. O resultado positivo do teste sorológico, permitiu a identificação de um paciente multibacilar, até então sem diagnóstico de hanseníase. Ademais, a utilização do teste sorológico LID nas atividades de busca ativa em áreas endêmicas para realização do diagnóstico precoce pode contribuir para o conceito zero hanseníase estipulado pela Organização Mundial da Saúde. (AU).

Leprosy is a chronic and infectious disease caused by Mycobacterium leprae (M. leprae). It has high infectivity and low pathogenicity. The aim of this study was to report the identification of a patient with multibacillary leprosy using the serological test (LID) during an active search. A 54-year-old male patient, living in Governador Valadares, Minas Gerais, Brazil, from the active search of the Leprosy Research Center (NuPqHans/UFJF-GV), presented a positive serological test for recombinant bacillus proteins (ML0405/ML2331). He was referred to the Reference Center for Endemic Diseases and Special Programs (CREDENPES), complaining of skin lesions and nodules all over his body, and reported a history of head trauma, occasional dizziness, numbness in his feet, and nosebleeds. The patient presented positive bacilloscopy and biopsy results, concluding the diagnosis of multibacillary leprosy and receiving the indicated multidrug therapy. After three months of treatment, there was a reduction in the area/diameter of the lesions on the abdomen, indicating the effectiveness of the treatment. The positive result of the serological test (LID) allowed the identification of a multibacillary patient, who until then had not been diagnosed with leprosy. In addition, the use of the LID serological test in active search activities in endemic areas for early diagnosis can contribute to the zero-leprosy concept stipulated by the World Health Organization.

Multibacillary leprosy with an incubation period exceeding 50 years.

Leprosy is a chronic granulomatous infection predominantly involving the skin and peripheral nervous system. The condition is caused by infection with the obligate intracellular bacillus Mycobacterium leprae and the clinical phenotype is largely dependent on the host immune response to the organism. Transmission is suspected to occur via respiratory secretions with infection usually requiring prolonged periods of contact. The incubation period is highly variable with disease manifestations appearing up to several decades after the initial exposure. The disease can be broadly divided into 'paucibacillary' and 'multibacillary', and treatment with multidrug therapy including dapsone, clofazimine and rifampicin offers high rates of cure. Here, we report of a case of leprosy with a suspected incubation period in excess of 50 years following occupational exposure in rural Australia. To our knowledge, this incubation period is the longest reported to date.

Chronic recalcitrant erythema nodosum leprosum: therapeutic dilemma and role of mycobacterium indicus pranii vaccine

Abstract Erythema nodosum leprosum is a severe immune reaction that complicates the usual course of multibacillary leprosy. There is increased activation of T-cells in erythema nodosum leprosum. Treatment modalities available to date for the management are systemic steroids, thalidomide, methotrexate, cyclophosphamide, azathioprine, minocycline, and apremilast but none of them is promising and safe. Mycobacterium indicus pranii is an atypical mycobacterium possessing strong immunomodulatory properties. The vaccine for this mycobacterium has been shown to have both immunotherapeutic and immunoprophylactic effects in multibacillary leprosy patients. We report a case of chronic recalcitrant erythema nodosum Leprosum which responded to Mycobacterium indicus pranii vaccine without any adverse effects, thereby suggesting its role as a novel therapeutic option in this reaction.

Introdução: A hanseníase é uma doença crônica, infectocontagiosa e considerada um problema de saúde pública no Brasil. O objetivo deste estudo foi descrever o seguimento farmacoterapêutico de pacientes com diagnóstico de hanseníase. Métodos: Estudo descritivo, com pacientes com hanseníase multibacilar do município de Rondonópolis, Mato Grosso. O seguimento farmacoterapêutico foi realizado a partir de uma versão adaptada do Método Dáder. Para análise de dados aplicou-se a estatística descritiva e o teste Qui-quadrado de Pearson.Resultados: Uma frequência de 95,6% dos participantes apresentou problemas relacionados aos medicamentos, 59,1% apresentaram 3 ou mais problemas, os mais frequentes foram administração errada do medicamento e interação medicamento/nutriente. A inefetividade não quantitativa foi o resultado negativo associado ao medicamento mais evidenciado. Os indivíduos acompanhados em um serviço especializado apresentaram menor número de problemas relacionados aos medicamentos quando comparados àqueles da Estratégia Saúde da Família (p = 0,027).Conclusão: A maioria dos pacientes acompanhados apresentou problemas relacionados ao uso de medicamentos. O método Dáder possibilitou realizar o seguimento farmacoterapêutico de indivíduos com hanseníase.

Introduction: Leprosy is a chronic, infectious, and contagious disease considered a public health problem in Brazil. The objective of this study was to describe the pharmacotherapy follow-up of patients diagnosed with leprosy. Methods: We conducted a descriptive study of patients with multibacillary leprosy in the city of Rondonópolis, state of Mato Grosso, Brazil. Pharmacotherapy follow-up was conducted based on an adapted version of the Dáder method. Data were analyzed using descriptive statistics and Pearson's chi-square test. Results: Drug-related problems (DRP) were reported in 95.6% of patients, among whom 59.1% had 3 or more problems DRPs. The most common DRPs were incorrect drug administration and drug-nutrient interaction. Nonquantitative ineffectiveness was the most common drug-related negative outcome. Patients monitored in a leprosy treatment center had fewer DRPs than those monitored by a Family Health Strategy team (p = 0.027). Conclusion: Most patients had DRPs. The Dáder method allowed pharmacotherapy follow-up of patients with leprosy.

Histoid leprosy presenting as a large tumor

Abstract Histoid leprosy is a rare form of multibacillary leprosy, characterized by the presence of papules, plaques, or nodules whose appearance is keloid-like, skin colored, or erythematous. Fusiform cells are the main histopathological feature. Due to the fact that it can simulate other dermatological lesions, for example, dermatofibroma and neurofibroma, it constitutes a diagnostic challenge for clinicians and pathologists. It is a bacilliferous form of leprosy, and it plays an important role in disease transmission. A case of a patient with histoid leprosy living in the Northeast Region of Brazil is reported.

Eritema nodoso hansênico com apresentação vesiculosa simulando infecção herpética: um relato de caso / Erythema nodosum leprosum with vesicular presentation simulating herpetic infection: a case report

Contexto: As reações hansênicas são episódios inflamatórios agudos imunomediados que podem ocorrer em indivíduos com hanseníase. Lesões atípicas de eritema nodoso hansênico (ENH) são raras e podem se apresentar como pústulas, bolhas, necrose, úlceras e, eventualmente, podem simular outras doenças como a síndrome de Sweet e eritema multiforme. Descrição do caso: Paciente do sexo masculino, 24 anos de idade, com diagnóstico prévio de hanseníase virchowiana e realização de tratamento adequado, com término da poliquimioterapia quatro anos antes de comparecer ao nosso serviço quando foi avaliado, apresentando pequenas vesículas translúcidas agrupadas sobre uma base eritematosa e áreas com crostas necróticas, simulando lesões herpéticas, na porção superior das costas, parte inferior do pescoço e haste do pênis. O exame histopatológico da biópsia cutânea foi sugestivo de reação tipo 2 e o tratamento com talidomida foi satisfatório. Discussão: As reações na hanseníase representam episódios de hipersensibilidade aguda a antígenos de Mycobacterium leprae e podem se desenvolver antes, durante ou após o término do tratamento. Acredita-se que o ENH, ou reações do tipo 2, ocorram devido à deposição de imunocomplexos em múltiplos órgãos em pacientes que apresentam a forma multibacilar. Conclusões: As reações hansênicas são desafios no manejo da hanseníase, especialmente pelo fato de a maioria das sequelas permanentes ser secundária a esses episódios inflamatórios agudos. O conhecimento das possíveis apresentações atípicas das reações hansênicas é fundamental para o diagnóstico precoce e o tratamento adequado, a fim de prevenir morbidade grave relacionada à hanseníase.

Leprosy-an unusual cause of a suspicious nodule on mammography.

A routine mammogram identified changes thought to be due to a lymph node, which was confirmed on biopsy. The lymph node was infiltrated with macrophages and showed fragmented acid-fast bacilli. The patient had been treated for leprosy some years before and was still taking thalidomide for erythema nodosum leprosum. Leprosy-associated lymphadenopathy may be identified on routine breast screening.

Cases of leprosy notified in the municipality of Parnaíba, state of Piauí, Brazil, 2007-2016

This study aimed to describe the epidemiological and clinical characteristics of leprosy cases reported in the municipality of Parnaíba, State of Piauí. This was a cross-sectional study of leprosy cases, living in Parnaíba, State of Piauí, reported to the National System of Notifiable Diseases (SINAN), from 2007 to 2016. There were 582 cases of leprosy with hyperendemic detection in the general population in 2008, 2009 and 2016; and under < 15 years of age in 2008, 2014 and 2016, with a predominance of females (53.1%), brown (62.2%), aged 20-64 years (74.7%), complete and incomplete elementary school (56.4%), housewives (20.7%), living in the urban area (87.1%), reported by primary care (69.2%). The most frequent clinical and therapeutic findings were: multibacillary operational classification (53.8%); clinical forms: undetermined (30.6%) and virchowian (24.3%); single lesion (34.8%); no affected nerves (86.7%); degree of disability zero (70.6%); bacilloscopy not performed (26.7%); therapeutic regimen 12 doses (53.7%) and no reaction (70.8%). Regarding the mode of input, predominated new case (88.8%); mode of output, cure (87.9%) and detection mode: spontaneous demand (45.8%). Out of 2,106 registered contacts, 60.6% were examined. Leprosy is endemic to Parnaíba, State of Piauí. It is noteworthy that the hyperendemic detection rates occurred during years when there was intensification of active search for contacts and cases in the population.

Magnitude and temporal trends of leprosy relapse in the state of Ceará, Brazil in the period 2001-2018

Abstract INTRODUCTION: This study analyzed the magnitude and temporal trends of leprosy relapse in Ceará in 2001-2018. METHODS: Descriptive cross-sectional and ecological-time trend studies were performed. RESULTS: We diagnosed 1,777 leprosy relapse cases. Higher prevalence of relapse was observed in men, illiterates, mixed race, multibacillary leprosy, lepromatous leprosy, and persons with visible disabilities. The proportion of relapse increased throughout the study period. CONCLUSIONS: Leprosy relapse is prevalent in certain groups.

Epidemiological characteristics and temporal trends of new leprosy cases in Brazil: 2006 to 2017 / Características epidemiológicas e tendências temporais de casos novos de hanseníase no Brasil: 2006 a 2017 / Características epidemiológicas y tendencias temporales de nuevos casos de lepra en Brasil: de 2006 a 2017

Abstract: Our study aims to describe trends in new case detection rate (NCDR) of leprosy in Brazil from 2006 to 2017 overall and in subgroups, and to analyze the evolution of clinical and treatment characteristics of patients, with emphasis on cases diagnosed with grade 2 physical disabilities. We conducted a descriptive study to analyze new cases of leprosy registered in the Brazilian Information System for Notificable Diseases (SINAN), from 2006-2017. We calculated the leprosy NCDR per 100,000 inhabitants (overall and for individuals aged < 15 and ≥ 15 years) by sex, age, race/ethnicity, urban/rural areas, and Brazilian regions, and estimated the trends using the Mann-Kendall non-parametric test. We analyzed the distributions of cases according to relevant clinical characteristics over time. In Brazil, there was a sharp decrease in the overall NCDR from 23.4/100,000 in 2006 to 10.3/100,000 in 2017; among children < 15 years, from 6.94 to 3.20/100,000. The decline was consistent in all Brazilian regions and race/ethnicity categories. By 2017, 70.2% of the cases were multibacillary, 30.5% had grade 1 (G1D) or 2 (G2D) physical disabilities at diagnosis and 42.8% were not evaluated at treatment completion/discharge; cases with G2D at diagnosis were mostly detected in urban areas (80%) and 5% of cases died during the treatment (leprosy or other causes). Although the frequency of leprosy NCDR decreased in Brazil from 2006 to 2017 across all evaluated population groups, the large number of cases with multibacillary leprosy, physical disabilities or without adequate evaluation, and among children suggest the need to reinforce timely diagnosis and treatment to control leprosy in Brazil.

Resumo: O estudo teve com objetivos descrever as tendências na taxa de detecção de casos novos (TDCN) de hanseníase no Brasil em 2006-2017, global e por subgrupos, e analisar a evolução das características clínicas e terapêuticas dos pacientes, com ênfase nos casos diagnosticados com incapacidade física grau 2. Realizamos um estudo descritivo par analisar casos novos de hanseníase registrados no Sistema de Informação de Agravos de Notificação (SINAN), 2006-2017. Calculamos a TDCN de hanseníase por 100.000 habitantes (global e para indivíduos < 15 e ≥ 15 anos de idade) por sexo, idade, raça/etnicidade, área urbana/rural e macrorregião do Brasil e estimamos as tendências com o teste não paramétrico de Mann-Kendall. Analisamos as distribuições de casos de acordo com características clínicas relevantes ao longo do tempo. No Brasil, houve uma queda marcante na TDCN global, de 23,4/100.000 em 2006 para 10,3/100.000 em 2017; entre crianças < 15 anos, de 6,94 para 3,20/100.000. A queda foi consistente em todas a regiões brasileiras e em todas as categorias de raça/etnicidade. Até 2017, 70,2% dos casos eram multibacilares, 30,5% apresentavam incapacidades físicas grau 1 (G1D) ou grau 2 (G2D) ao diagnóstico e 42,8% não foram avaliados ao encerramento do tratamento ou alta; os casos com G2D ao diagnóstico foram detectados majoritariamente nas áreas urbanas (80%), e 5% dos casos faleceram durante o tratamento (devido à hanseníase ou por outras causas). Embora a frequência da TDCN da hanseníase tenha diminuído no Brasil entre 2006 e 2017 em todos os grupos avaliados, o número grande de casos com hanseníase multibacilar, incapacidades físicas ou sem avaliação adequada e entre crianças sugere a necessidade de reforçar o diagnóstico e tratamento oportunos para controlar a hanseníase no Brasil.

Resumen: Se realizó este trabajo con el fin de describir la tendencia general y en subgrupos de la tasa de detección de nuevos casos de lepra (NCDR por sus siglas en inglés) en Brasil, entre 2006-2017, así como para analizar la evolución de las características clínicas y de tratamiento de los pacientes, con énfasis en los casos diagnosticados con un grado 2 de discapacidad física. Realizamos un estudio descriptivo para analizar los nuevos casos de lepra registrados en el Sistema Brasileño de Información de Enfermedades de Notificación (SINAN), 2006-2017. Calculamos la NCDR de lepra por cada 100.000 habitantes (general e individuos con una edad < 15 y ≥ 15 años) por sexo, edad, raza/etnicidad, áreas urbanas/rurales y regiones brasileñas, y estimamos las tendencias usando el test no paramétrico de Mann-Kendall. Analizamos las distribuciones de casos según las características clínicas relevantes a lo largo del tiempo. En Brasil, hubo una drástica disminución en general de NCDR de los 23,4/100.000 en 2006, a los 10,3/100.000 en 2017; entre niños < 15 años, desde los 6,94 a los 3,20/100.000. El decremento fue consistente en todas las regiones brasileñas y categorías de raza/etnicidad. En 2017, un 70,2% de los casos fueron multibacilares, un 30,5% tenían grado 1 (G1D) o 2 (G2D) discapacidad física en el diagnóstico y un 42,8% no fueron evaluados al completar el tratamiento/ser dados de alta; casos con G2D en el diagnóstico fueron en su mayoría detectados en áreas urbanas (80%) y un 5% de los casos murieron durante el tratamiento (lepra u otras causas). A pesar de la frecuencia de lepra los NCDR decrecieron en Brasil de 2006 a 2017, a través de todos los grupos de población evaluados, el elevado número de casos con lepra multibacilar, discapacidad física o sin una adecuada evaluación, y entre niños sugiere la necesidad de reforzar a tiempo el diagnóstico y tratamiento para controlar la lepra en Brasil.

Rationale use of Thalidomide in erythema nodosum leprosum - A non-systematic critical analysis of published case reports.

INTRODUCTION: Thalidomide is an anti- tumor necrosis factor alpha (TNF-a) drug used mainly in the management of moderate to severe form of Erythema Nodosum Leprosum (ENL). Because of its teratogenic potential it has to be used under proper supervision. Our critical analysis tries to look into the rationale with which it has been used by means of case reports on lepra reaction. METHODS: We looked for the case reports between December 2005 to June 2019 in databases like Pubmed, Embase and other relevant resources. We used search words like "erythema nodosum leprosum(ENL)", "thalidomide", "case report" in different combinations to get relevant reports that focus on thalidomide usage atleast once at any time point during management. The information extracted were indication of thalidomide use, dose, response, outcome, complication if any, along with all the demographic details and geographical distribution. RESULTS: We found 41 case reports eligible for analysis.The information was critically evaluated. From the analysis it was found that 7 of the case report mentioned the exact indication, 4 case report showed irrational use of thalidomide in the case of neuritis without use of steroids, 7 showed proper use of Clofazimine prior to thalidomide initiation, 26 case report showed case report of rationale dose range and in 4 case reports clofazimine was used prior to thalidomide along with the rational dose of thalidomide. CONCLUSIONS: This analysis helps to guide the rationale use of thalidomide focussing on few important points that anyone should keep in mind while managing a case of ENL.

Lazarine leprosy: A unique phenomenon of leprosy.

Leprosy, a chronic granulomatous disease, has been known since ages but even today continues to baffle the clinicians with a wide spectrum of clinical, histopathological, and immunological characteristics. Leprosy reactions are mainly of two types, namely, Type 1 and Type 2. In Type 1 leprosy reaction, the preexisting lesions become erythematous, edematous, and rarely ulcerate. Ulcerating Type 1 reaction is called lazarine leprosy. Ulcerations may occur in borderline tuberculoid (BT) pole or borderline lepromatous pole but more common in BT pole. In this postelimination era of leprosy, we report an interesting case report of BT Hansen's disease with Type 1 lepra reaction with ulceration, namely, lazarine leprosy.

Clinicobacteriological evaluation of leprosy patients with 1-5 skin lesions.

Background: Mycobacterium leprae is a noncultivable mycobacteria, and diagnosis of the disease is based on its clinical and histopathological characteristics and finding the bacteria in skin scrapings and in biopsies taken from the patients. The aim of this study was to shed light on the clinical classification (based on the number of skin lesions) used extensively in the field where patients classified as paucibacillary (PB) were positive on skin smears and histopathology leading to treatment failure and drug resistance. Methods: In this study, we enrolled untreated 62 leprosy patients with 1-5 skin lesions and did a detailed bacterio-histopathological analysis by slit-skin smears (SSSs) and histopathology. Results: Of 62 patients analyzed, 15 patients came out to be multibacillary (MB) and 47 were PB by SSS and histopathology. Conclusion: The findings of the present study showed that the WHO classification of leprosy based on the number of lesions seems to be inappropriate as it considers a number of MB lesions as PB only, thus misleading the treatment strategies. Hence, it is essential that a comprehensive clinicobacteriological assessment of leprosy cases should be done to ensure the appropriate bacillary status and guiding the appropriate treatment strategy.
