Leprosy in Colombia: A look from life experience.

Leprosy continues to be stigmatized, causing harm to fundamental rights, pain and hopelessness in those who have suffered from it and their families. From its relationship with public and mental health, effective strategies must be implemented to reduce stigma and unlearn myths and wrong perceptions, support families, and improve quality of life through early care and detection. This article shows that those affected by leprosy are capable, functional people with much to contribute to society anywhere in the world.

An evaluation of mental health integration in the neglected tropical diseases program in Zamfara, North-west Nigeria.

BACKGROUND: Mental health and neglected tropical diseases (NTDs) are critical in healthcare systems, especially in low- and middle-income countries. Several policies are planned or designed by health stakeholders to address the mental health needs of people affected by NTDs. Still, the impact of such policies seems to be of no consequence. METHODS: The GAD-7 and PHQ-9 tools were used to determine the rate of depression and anxiety, respectively, among people affected by skin NTDs (leprosy and lymphatic filariasis [LF]) in Zamfara State, North-west Nigeria. The study also evaluated the barriers to the uptake of mental health services for people affected by skin NTDs in the state. We assessed 48 people affected by NTDs (leprosy, 32; lymphatic filariasis, 16) along with a corresponding 48 people who served as controls in the study. Qualitative interviews were carried out with the participants to elicit the barriers to mental health services for people affected by NTDs. Additionally, 48 selected healthcare workers from the state were assessed for their skills and capacity to offer mental health services. RESULTS: We found anxiety disorder present in 100% of the people living with LF and in 62% of the people living with leprosy. Depression was also found in 56% and 75% of the people living with leprosy and LF, respectively. An assessment of the barriers to the uptake of mental health services reveals that most people with NTDs are constrained by a lack of money to visit hospitals, the fear of stigmatisation and discrimination and long distances to health centres. Regarding the healthcare workers, the skills and capacity to offer mental health services were very low. CONCLUSIONS: We conclude that for mental health services to be integrated into the community health system for people with NTDs, there should be a concerted effort by all stakeholders and the intervention should be context specific instead of generalised. CONTEXTE: La santé mentale et les maladies tropicales négligées (MTN) sont des problématiques centrales dans la santé, en particulier dans les pays à revenu faible ou intermédiaire. Plusieurs politiques sont conçues par les acteurs de la santé publique pour répondre aux besoins de soins en santé mentale pour les personnes touchées par les MTN. Pourtant, le bilan reste mitigé quant à l'efficacité de ces soins. MÉTHODES: Les outils GAD-7 et PHQ-9 ont été utilisés pour déterminer le taux de dépression et d'anxiété chez les personnes atteintes de MTN cutanées (lèpre et filariose lymphatique) dans l'État de Zamfara, au nord-ouest du Nigeria. L'étude a également évalué les obstacles à l'utilisation des services de santé mentale pour les personnes atteintes de MTN cutanées dans l'État. Nous avons évalué 48 personnes atteintes de MTN (lèpre : 32, filariose lymphatique : 16) ainsi que 48 personnes correspondantes qui ont servi de témoins dans l'étude. Des entretiens qualitatifs ont été menés avec les participants afin d'identifier les obstacles aux services de santé mentale pour les personnes atteintes de MTN. En outre, 48 professionnels de la santé sélectionnés dans l'État ont été évalués pour déterminer leurs compétences et leur capacité à offrir des services de santé mentale. RÉSULTATS: Nous avons trouvé des troubles anxieux chez 100% des personnes atteintes de filariose lymphatique et chez 62% des personnes atteintes de lèpre. La dépression touche 56% et 75% des personnes vivant avec la lèpre et la filariose lymphatique respectivement. Une évaluation des obstacles à l'utilisation des services de santé mentale révèle que la plupart des personnes atteintes de MTN sont limitées par le manque d'argent pour se rendre à l'hôpital, la peur de la stigmatisation et de la discrimination, et les longues distances à parcourir pour se rendre dans les centres de santé. Les compétences et les capacités des professionnels de la santé à offrir des services de santé mentale sont très faibles. CONCLUSION: L'efficacité d'un protocole de soins pour les patients atteints de MTN (traitant la pathologie physique et d'éventuelles pathologies psychiatriques associées) nécessite une intégration des services de santé mentale dans le système de santé communautaire. ANTECEDENTES: La salud mental y las enfermedades tropicales desatendidas (ETDs), son fundamentales en los sistemas sanitarios, especialmente en los países de renta baja y media. Las partes interesadas en la sanidad planean o diseñan varias políticas para abordar las necesidades de salud mental de las personas afectadas por ETDs. Sin embargo, el impacto de dichas políticas parece ser nulo. MÉTODOS: Se utilizaron las herramientas GAD-7 y PHQ-9 para determinar la tasa de depresión y ansiedad, respectivamente, entre las personas afectadas por ETDs cutáneas (lepra y filariasis linfática) en el Estado de Zamfara, al noroeste de Nigeria. El estudio también evaluó las barreras para la aceptación de los servicios de salud mental por parte de las personas afectadas por ETDs cutáneas en el Estado. Se evaluó a 48 personas afectadas por ETDs (lepra: 32; filariasis linfática: 16) y a otras 48 que sirvieron de control en el estudio. Se llevaron a cabo entrevistas cualitativas con los participantes para determinar las barreras a los servicios de salud mental para las personas afectadas por ETDs. Además, se evaluaron las habilidades y la capacidad para ofrecer servicios de salud mental de 48 profesionales sanitarios del Estado. RESULTADOS: Encontramos trastorno de ansiedad presente en el 100% de las personas que vivían con filariasis linfática y en el 62% de las personas que vivían con lepra. También se encontró depresión en el 56% y el 75% de las personas que vivían con lepra y filariasis linfática respectivamente. Una evaluación de los obstáculos para la utilización de los servicios de salud mental revela que la mayoría de las personas con ETDs se ven limitadas por la falta de dinero para acudir a los hospitales, el miedo a la estigmatización, la discriminación y las largas distancias hasta los centros sanitarios. Por parte del personal sanitario, los conocimientos y la capacidad para ofrecer servicios de salud mental eran muy escasos. CONCLUSIONES: Para que los servicios de salud mental para personas con ETD se integren en el sistema sanitario comunitario, debe haber una concertación entre todas las partes interesadas y la intervención debe ser específica para cada contexto en lugar de generalizada.

Prevalence of oral manifestations of leprosy: a systematic review and meta-analysis.

OBJECTIVE: To evaluate the prevalence of oral manifestations of leprosy. STUDY DESIGN: This systematic review with meta-analysis was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and included cross-sectional studies by 2 independent reviewers in 2 phases, who reported bacilloscopic-confirmed oral manifestations of leprosy. Studies were selected based on predetermined eligibility criteria. Searches in 6 main databases were performed, such as PubMed/MEDLINE, Embase, Scopus, Web of Science, LILACS/BVS, and LIVIVO, in addition to the gray literature. The risk of bias was assessed using the JBI Checklist for Analytical Cross-Sectional Studies, and the quantitative synthesis of the data was performed using the Jamovi 2.3 application. RESULTS: Ten studies were included, and the meta-analysis was performed with 917 patients with different types of leprosy. The overall prevalence of oral alterations was 6.0% (95% IC, 0.02-0.11; I2 = 97.01%; Q = 75.56), with plaques (27.2%), infiltrations (18.1%), and macules (15.1%) being the most prevalent fundamental lesions, especially in multibacillary patients. CONCLUSIONS: Even though there is no oral pathognomonic lesion of leprosy, this infectious disease can manifest in oral tissues in different ways, depending mainly on the leprosy type and stage of treatment.

Nutritional Status in Leprosy Patients: A Systematic Review and Meta-analysis.

BACKGROUND: Leprosy, a chronic mycobacterial disease, is frequently accompanied by malnutrition. However, it is important to regularly assess the nutritional state of leprosy patients in a resource-poor nation like India, where undernutrition is widespread. OBJECTIVES: This study aimed to compare the nutritional status of leprosy patients to that of normal individuals using the body mass index. METHODS: The electronic databases PubMed, Google Scholar, and Embase were used to conduct an open literature search. From 1st January 2000 to 31st January 2023, all articles were screened using the following MeSH terms: (nutrition OR body mass index OR body weight) AND (leprosy OR lepra) to find possibly relevant articles. RESULTS: This meta-analysis includes five research studies with a total of 1173 individuals (363 patients in the leprosy group and 810 patients in the non-leprosy group). The weighted mean difference (WMD) for BMI studies was -17.88 (95% CI -27.65 to -8.12), showing that there was a significant difference in BMI < 18.5 between leprosy patients and non-leprosy patients. There was a significant difference in DDS score and HFIAS score between patients with leprosy and non-leprosy. In a total of 342 leprosy patients, 206 developed deformities. CONCLUSION: This research increases our understanding of nutrition and leprosy. The results found that people with leprosy are nutritionally at a distinct disadvantage when compared to non-leprosy patients. It emphasises the several ways in which diet may generate circumstances that increase the risk of leprosy.

The spectrum of central nervous system manifestations in leprosy: a systematic review of published case reports and case series.

BACKGROUND: This systematic review aimed to investigate central nervous system (CNS) involvement in leprosy by analysing multiple cohort studies, individual cases and case series. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. PubMed, Scopus and Embase databases were searched up to 8 July 2023, using a predefined search strategy. Inclusion criteria included patients diagnosed with leprosy with evidence of CNS involvement. The quality of the included cases was evaluated using the Joanna Briggs Institute checklist. RESULTS: A total of 34 records were identified, including 18 cohort studies and 16 reports describing 27 isolated cases. Autopsies revealed macroscopic changes in the spinal cord, neurofibrillary tangles and senile plaques. Mycobacterium leprae was detected in neurons of the medulla oblongata and spinal cord using PCR and phenolic glycolipid 1 staining. Cerebrospinal fluid (CSF) analysis showed inflammatory changes, increased gamma globulins and detection of Mycobacterium leprae antigens and antibodies. In 21 patients (78%), spinal cord/brachial plexus abnormities were detected. In the majority, MRI revealed T2/fluid-attenuated inversion recovery (FLAIR) hyperintensity in the cervical cord. In patients with brainstem involvement, T2/FLAIR hyperintensity was noted in the cerebellar peduncles, facial nerve nuclei and/or other cranial nerve nuclei. Brain parenchymal involvement was noted in three patients. CONCLUSIONS: This systematic review provides evidence of CNS involvement in leprosy, based on autopsy findings, neuroimaging, CSF analysis and neurophysiological studies.

Reverse Koebner phenomenon in erythema nodosum leprosum.

BACKGROUND: Erythema nodosum leprosum (ENL) is an immunologically mediated phenomenon complicating the course of leprosy. Reverse Koebner phenomenon is the term used to describe the sparing of previously injured or diseased skin by new skin lesions of the disease. METHODS: A middle-aged woman with a known case of lepromatous leprosy for the past year presented with an eruption of reddish painful nodules over her body. The lesions were found to characteristically spare the sites of previous scars. RESULTS: This sparing phenomenon of previous scar sites has been termed reverse Koebner phenomenon, a site of the body that offers greater resistance than the rest of the body to the onset of the disease, seen in various diseases, but it has never been described in ENL. CONCLUSION: This sparing of scar sites in ENL can be attributed to reverse Koebner phenomenon.

Pre- and post-surgical evaluation of the impact on Hansen disease sequealae patients' quality of life submitted to orthopedic surgery for closure of chronic plantar ulcers.

INTRODUCTION: Leprosy is a chronic infectious disease that still persists as a public health problem in Brazil. Plantar ulcers are serious complications due to leprosy neuropathy and intensify the isolation and stigma of these individuals. The difficulty in closing these lesions associated with the fetid odor negatively impact the quality of life of people with these lesions. OBJECTIVE: To evaluate the clinical, socioeconomic conditions, degree of satisfaction and quality of life (QoL) of patients after healing of chronic ulcers on feet submitted to orthopedic surgery. METHODOLOGY: This is a qualitative, exploratory, descriptive and observational study carried out with 92 people after surgical treatment of chronic leprosy plantar ulcers. These patients were submitted to a semi-structured questionnaire raising questions of an epidemiological, socioeconomic and perception of quality-of-life order, comparing before and after the surgical procedure. RESULTS: Decrease in indicators - alcohol consumption, tobacco consumption, average monthly cost of analgesic medications, fetid wound odor, foot pain and number of dressings performed weekly; Recurrence of lesions in 55.4 % of cases, related to irregular use or lack of shoes and insoles; Improvement in self-perception of Quality of Life (QoL) in 89.1 % of patients after surgery. CONCLUSION: Orthopedic surgical treatment with resection of plantar bony prominences and skin grafting is an effective therapeutic method for closing chronic plantar ulcers in leprosy, resulting in a decrease in the financial costs employed and in an important improvement in the Quality-of-Life parameters of the individuals undergoing to this procedure. The availability and regular use of shoes and insoles is crucial to prevent recurrence of these injuries.

Application of a physiotherapeutic protocol associated with photobiomodulation for the treatment of leprosy patients.

Leprosy is a chronic infectious disease characterized by acute inflammatory episodes that affect the skin and peripheral nerves and can develop progressive and irreversible disabilities and deformities. In addition, drug therapy and physiotherapy offer resources and techniques capable of mitigating the consequences of neural lesions, but neural lesions can occur before, during, and even after drug treatment. Thus, new treatments are needed. Photobiomodulation (PBM) might be a promissor therapy since it aims to reduce the inflammatory process and restore motor and sensory functions in the affected area. This study aims to compare the evolution of neural status, pain, and functionality in patients with leprosy and neuritis after a physiotherapeutic protocol and PBM treatment. This was a randomized controlled clinical trial that analyzed a group of patients receiving a physiotherapeutic protocol (PPG) and another receiving physiotherapeutic protocol associated with PBM (PLG) (wavelength 904 nm, potency 70 mW, time per point 9 s). Our results showed when evaluating functional capacity limitations with the SALSA scale, the PLG patients improved from moderate to mild limitations. On the other hand, the PPG remained as moderate limitations. Also, the PLG showed a significant reduction in pain on the VAS scale. The neurological assessment showed that PLG improved palpation of the median, radial, and peroneal nerves. In the strength test, PLG patients improved in the 5th finger abduction and ankle dorsiflexion. Assessing sensitivity, it was identified an improvement in PLG for the ulnar nerve and tibial nerve. All those changes were statistically significant when compared to the PPG patients. Finally, the PLG patients improved disabilities, identified by the neurological assessment of the eyes, hands, and feet. In conclusion, this study demonstrated that combining a physiotherapeutic protocol with PBM treatment effectively improved functional status and reduced pain in leprosy patients.

Impact of basic psychological support on stigma and mental well-being of people with disabilities due to leprosy and lymphatic filariasis: a proof-of-concept study.

BACKGROUND: People with leprosy and lymphatic filariasis (LF)-related disabilities experience higher levels of poor mental well-being compared with the general community. Mental health services are often not available. This study was conducted to provide proof of concept that basic psychological support for people affected by neglected tropical diseases (BPS-N) can be given by peer supporters to reduce stigma, improve mental well-being and participation among clients. METHODS: The BPS-N approach was tested in a quasi-experimental design using mixed methods. To provide psychological support using the BPS-N, peer supporters were selected and trained. They supported people with leprosy- and LF-related disabilities. Preintervention and postintervention, stigma, mental well-being, depression and participation were measured through standard scales within 4 wk of the intervention; differences were tested using standard tests of significance. RESULTS: After 3 mo of intervention, the mean level of stigma had decreased (30.3 to 24, p<0.001); high mental well-being increased (0% to 13.3%, p<0.001); and moderate to severe depression decreased (88% to 47%, p<0.001). No significant change occurred in participation restrictions (87% to 92%, p=0.497). CONCLUSIONS: Psychological peer support using the BPS-N guideline appears effective in reducing stigma and improving mental well-being and can be operationalised. However, this should be confirmed through a randomised controlled trial. CONTEXTE: Les personnes atteintes de lèpre et de handicaps liés à la filariose lymphatique (FL) souffrent davantage d'un manque de bien-être mental que le reste de la population. Les services de santé mentale ne sont souvent pas disponibles hors des zones urbaines. Cette étude a été menée pour démontrer que le soutien psychologique de base pour les personnes atteintes de MTN (BPS-N) peut être dispensé par des pairs (dans une logique de transfert de tâches) afin de réduire la stigmatisation et d'améliorer le bien-être mental et la participation des clients. MÉTHODES: L'approche du BPS-N a été testée dans le cadre d'un modèle quasi-expérimental utilisant des méthodes mixtes. Pour fournir un soutien psychologique à l'aide du BPS-N, des pairs ont été sélectionnés et formés. Ils sont venus en aide aux personnes atteintes de lèpre et de déficiences liées à la FL. Avant et après l'intervention, les éléments suivants ont été mesurés à l'aide d'échelles standardisées: niveau de stigmatisation, bien-être mental, symptômes dépressifs, et enfin, la participation sociale. Les différences ont été testées à l'aide de tests de signification standardisés. RÉSULTATS: Après 3 mois d'intervention, le niveau moyen de stigmatisation a diminué (30,3 à 24, p<0 001) ; le niveau de bien-être mental a augmenté (0% à 13,3%, p<0 001) et la dépression modérée à sévère a diminué (88% à 47%, p<0 001). Aucun changement significatif n'a été observé en ce qui concerne les restrictions de participation (87% contre 92%, p=0 497). CONCLUSIONS: Le soutien psychologique par les pairs utilisant la ligne directrice BPS-N semble efficace pour réduire la stigmatisation et améliorer le bien-être mental. Toutefois, cette efficacité doit être confirmée par un essai contrôlé randomisé. ANTECEDENTES: Las personas con lepra y discapacidades relacionadas con la filariasis linfática (FL) sufren niveles más altos de malestar mental en comparación con la comunidad en general. Los servicios de salud mental no suelen estar disponibles a nivel periférico. Este estudio se llevó a cabo para proporcionar una prueba de concepto de que el Apoyo Psicológico Básico para personas afectadas por NTDs (BPS-N) puede ser dado por compañeros de apoyo (rotación de tareas) para reducir el estigma, mejorar el bienestar mental y la participación entre los clientes. MÉTODOS: El enfoque BPS-N se probó en un diseño cuasi-experimental utilizando métodos mixtos. Para proporcionar apoyo psicológico con el BPS-N, se seleccionaron y formaron compañeros de apoyo. Apoyaron a personas con lepra y discapacidades relacionadas con la FL. El estigma, el bienestar mental, la depresión y la participación se midieron antes y después de la intervención, mediante escalas estándar; las diferencias se comprobaron mediante pruebas estándar de significación. RESULTADOS: Después de 3 meses de intervención, el nivel medio de estigma disminuyó (30,3 a 24, p<0 001); el bienestar mental alto aumentó (0% a 13,3%, p<0 001) y la depresión moderada a grave disminuyó (88% a 47%, p<0 001). No se produjeron cambios significativos en las restricciones de participación (87% frente a 92%, p=0 497)). CONCLUSIONES: El apoyo psicológico entre iguales, utilizando la guía BPS-N, parece eficaz para reducir el estigma y mejorar el bienestar mental. Sin embargo, esto debe confirmarse mediante un ensayo controlado aleatorizado.

Impact of basic psychological support on stigma and the mental well-being of people with disabilities due to leprosy and lymphatic filariasis: a postintervention evaluation study.

BACKGROUND: A peer support intervention, called basic psychological support for people affected by neglected tropical diseases (BPS-N), was piloted in India to improve mental well-being and social participation and to reduce stigma among people with disabilities due to leprosy or lymphatic filariasis. Preintervention and postintervention assessments showed improvements in mental well-being and reductions in depression and stigma. This study aimed to further evaluate this intervention at approximately 2 mo after its completion. METHODS: Scales were administered to 62 clients to measure stigma, depression, mental well-being and participation levels. Interviews with 13 clients and six peer supporters were conducted. RESULTS: Stigma scores were significantly reduced at 2 mo postintervention compared with preintervention and postintervention. The improvement in mental well-being detected at immediate postintervention had not changed significantly 2 mo later. Depression levels were higher than at postintervention, but lower than at preintervention levels. No significant differences were found in median participation scores, but the number of clients with moderate and severe participation restrictions reduced significantly from postintervention to 2 mo follow-up. Qualitative results showed that clients received information about their condition and treatment, and that some experienced positive effects on their emotions and self-esteem. CONCLUSIONS: This study provides additional evidence on the proof of concept of BPS-N. CONTEXTE: Une intervention de soutien par les pairs, appelée Soutien psychologique de base pour les personnes atteintes de maladies tropicales négligées (BPS-N), a été pilotée en Inde afin d'améliorer le bien-être mental et la participation sociale, et de réduire la stigmatisation, chez les personnes souffrant d'incapacités dues à la lèpre ou à la filariose lymphatique. Les évaluations avant et après l'intervention ont montré une amélioration du bien-être mental et une réduction de la dépression et de la stigmatisation chez ces personnes. Cette étude avait pour but d'évaluer cette intervention environ 2 mois après son achèvement. MÉTHODES: Des échelles ont été administrées à 62 clients pour mesurer la stigmatisation, la dépression, le bien-être mental et les niveaux de participation. Des entretiens ont été menés avec 13 clients et 6 pairs aidants. RÉSULTATS: Les scores de stigmatisation ont été significativement réduits deux mois après l'intervention par rapport à la situation avant et après l'intervention. L'amélioration du bien-être mental détectée immédiatement après l'intervention n'a pas changé de manière significative deux mois plus tard. Les niveaux de dépression étaient plus élevés qu'après l'intervention, mais plus bas qu'avant l'intervention. Aucune différence significative n'a été constatée dans les scores médians de participation, mais le nombre de clients ayant des restrictions de participation modérées et sévères a diminué de manière significative entre la période post-intervention et les deux mois de suivi. Les résultats qualitatifs ont montré que les clients ont reçu des informations sur leur état et leur traitement, et que certains ont ressenti des effets positifs sur leurs émotions et leur estime de soi. CONCLUSIONS: Cette étude a fourni des preuves supplémentaires de l'efficacité de la BPS-N. INTRODUCCIÓN: Una intervención de apoyo entre iguales, denominada Apoyo Psicológico Básico para personas afectadas por enfermedades tropicales desatendidas (BPS-N), se puso a prueba en la India para mejorar el bienestar mental y la participación social y reducir el estigma entre las personas con discapacidades debidas a la lepra o la filariasis linfática. Las evaluaciones previas y posteriores a la intervención mostraron mejoras en el bienestar mental y reducciones en la depresión y el estigma. El objetivo de este estudio era seguir evaluando esta intervención ∼2 meses después de su finalización. MÉTODOS: Se administraron escalas a 62 clientes para medir el estigma, la depresión, el bienestar mental y los niveles de participación. Se realizaron entrevistas con 13 clientes y 6 compañeros de apoyo. RESULTADOS: Las puntuaciones de estigma se redujeron significativamente a los 2 meses de la intervención, en comparación con antes y después de la misma. La mejora del bienestar mental detectada inmediatamente después de la intervención no había cambiado significativamente 2 meses después. Los niveles de depresión eran más altos que en el postintervención, pero más bajos que en el preintervención. No se encontraron diferencias significativas en las puntuaciones medias de participación, pero el número de clientes con restricciones de participación moderadas y graves se redujo significativamente entre el periodo posterior a la intervención y los 2 meses de seguimiento. Los resultados cualitativos mostraron que los clientes recibieron información sobre su enfermedad y tratamiento, y que algunos experimentaron efectos positivos en sus emociones y autoestima. CONCLUSIONES: Este estudio aportó pruebas adicionales sobre la prueba de concepto de la BPS-N.

Steps towards eliminating Hansen's disease stigma.

Persons affected by Hansen's disease (PAHD) can develop long-term physical disabilities and psychological problems if the disease is not managed promptly and correctly. The complex and multi-faceted nature of stigma related to Hansen's Disease, and the discrimination arising from it, demands multiple parallel steps to improve the health, well-being and lived experience of People Affected by Hansen's Disease, including: 1) adoption and pursuance of a human rights based approach; 2) revocation of discriminatory laws; 3) education and training for healthcare workers; 4) new techniques and therapies to diagnose and treat HD without side-effects and to reduce risk of disabilities; 5) elimination of stigmatising terminology.

Co-infection of Mycobacterium tuberculosis and Mycobacterium leprae Complicated by pulmonary embolism: A rare case report.

A 35-year-old male patient with lepromatous leprosy came to the emergency room (ER) due to breathlessness and chest pain. The patient was diagnosed with pulmonary tuberculosis (TB) after a bronchoscopy and started on antitubercular therapy. However, the patient continued to experience tachycardia and desaturation, and on further evaluation, Computed tomography pulmonary angiography revealed an embolus in the right descending pulmonary artery. The patient was found to have an elevated d-dimer. Further investigation revealed that the cause of the pulmonary thromboembolism (PTE) was the thalidomide medication that the patient was taking for type 2 leprosy reaction. The medication was stopped, and the patient was treated with low-molecular-weight heparin and discharged with apixaban for six months. The patient's condition improved on follow-up. This case is unique due to the rare combination of pulmonary TB, leprosy, and pulmonary embolism brought on by thalidomide administration. Physicians should be aware of the possibility of co-infection of TB and leprosy and the need to rule out thromboembolism when patients are on thalidomide.

Assessment of Clinical, Histopathological, and Bacteriological Findings in Treated Leprosy Patients with Persistent Skin Lesions: A Retrospective Cohort Study.

Since the introduction of multidrug therapy (MDT), various disabilities/morbidities due to leprosy have been prevented. However, there is a subset of patients in whom the skin lesions do not resolve completely or remain unchanged despite a full course of MDT, which is a great source of anxiety to the patient and their family members. Hence, we tried to ascertain the putative causes and risk factors of persistent skin lesions (PSLs) by analyzing the clinical, histopathological, bacteriological, and drug resistance patterns. This is a retrospective, cohort study wherein 35 patients who had PSLs after completion of MDT were included. The majority of the patients were 18 to 30 years of age, with males predominating. Borderline tuberculoid leprosy was the most common clinical spectrum observed (71.4%). The majority had PSLs distributed predominantly over photo-exposed sites (upper limbs > trunk > face). Eight patients (22.8%) had a history of contact with leprosy patients in their family, and six patients (17.1%) had associated comorbidities. Improvement in histopathological parameters such as a decrease in granuloma fraction was observed in 22 patients (62.8%) with PSLs after release from treatment in comparison with baseline. Four patients (11.4%) were noted to have drug resistance (three to rifampicin and one to dapsone). Thus, our study emphasizes that leprosy patients with PSLs after completion of MDT should undergo histopathological evaluation and drug resistance studies.

Prevalence of plantar ulcer and its risk factors in leprosy: a systematic review and meta-analysis.

BACKGROUND: Plantar ulcers are a leading complication of leprosy that requires frequent visits to hospital and is associated with stigma. The extent of burden of ulcers in leprosy and its risk factors are scant impeding the development of targeted interventions to prevent and promote healing of ulcers. The aim of this review is to generate evidence on the prevalence of plantar ulcer and its risk factors in leprosy. METHODS: Databases (Medline, Embase, Web of Science, CINAHL, BVS), conference abstracts and reference lists were searched for eligible studies. Studies were included that reported a point prevalence of plantar ulcer and/or its "risk factors" associated with development of ulcers (either causatively or predictively), including individual level, disease related and bio-mechanical factors. We followed PRISMA guidelines for this review. Random-effects meta-analysis was undertaken to estimate the pooled point prevalence of ulcers. Reported risk factors in included studies were narratively synthesised. This review is registered in PROSPERO: CRD42022316726. RESULTS: Overall, 15 studies (8 for prevalence of ulcer and 7 for risk factors) met the inclusion criteria. The pooled point prevalence of ulcer was 34% (95% CIs: 21%, 46%) and 7% (95% CIs: 4%, 11%) among those with foot anaesthesia and among all people affected by leprosy, respectively. Risk factors for developing ulcers included: unable to feel 10 g of monofilament on sensory testing, pronated/hyper-pronated foot, foot with peak plantar pressure, foot with severe deformities, and those with lower education and the unemployed. CONCLUSIONS: The prevalence of plantar ulceration in leprosy is as high as 34% among those with loss of sensation in the feet. However, the incidence and recurrence rates of ulceration are least reported. The inability to feel 10 g of monofilament appears to be a strong predictor of those at risk of developing ulcers. However, there is a paucity of evidence on identifying those at risk of developing plantar ulcers in leprosy. Prospective studies are needed to estimate the incidence of ulcers. Identifying individuals at risk of ulcers will help design targeted interventions to minimize risk factors, prevent ulcers and promote ulcer healing.

Leprosy with type 1 reaction in a patient from Ontario, Canada without recent travel misdiagnosed as vasculitic neuropathy: a case report.

BACKGROUND: Leprosy is rare within non-endemic countries such as Canada, where cases are almost exclusively imported from endemic regions, often presenting after an incubation period of as many as 20 years. Due to its rarity and prolonged incubation period, diagnosis is often delayed, which may result in neurologic impairment prior to the initiation of treatment. In this report we describe a case that is novel in its incubation period, which is the longest reported to-date and may have contributed to diagnostic delay. The case also uniquely demonstrates the challenges of distinguishing leprosy reactions from new rheumatologic manifestations in a patient with established autoimmune disease. CASE PRESENTATION: We describe an 84-year-old male patient with rheumatoid arthritis on methotrexate and hydroxychloroquine, with no travel history outside Canada for 56 years, who presented in 2019 with new-onset paresthesias and rash. His paresthesias persisted despite a short course of prednisone, and his rash recurred after initial improvement. He underwent skin biopsy in May 2021, which eventually led to the diagnosis of leprosy. He was diagnosed with type 1 reaction and was started on rifampin, dapsone, clofazimine and prednisone, with which his rash resolved but his neurologic impairment remained. CONCLUSION: This case report serves to highlight the potential for leprosy to present after markedly prolonged incubation periods. This is especially relevant in non-endemic countries that is home to an aging demographic of individuals who migrated decades ago from endemic countries. The importance of this concept is emphasized by the persistent neurologic impairment suffered by our case due to untreated type 1 reaction. We also demonstrate the necessity of skin biopsy in distinguishing this diagnosis from other autoimmune mimics in a patient with known autoimmune disease.

Total knee arthroplasty for neuropathic arthropathy in a patient with leprosy.

Patients with leprosy are known to tend to develop neuropathic arthropathy, known as Charcot joint. There are no case reports of total knee arthroplasty (TKA) in patients with leprosy with polyarticular neuropathic arthropathy, and the results are unknown. In this study, we report a case of TKA in a patient with leprosy with polyarticular neuropathic arthropathy and discuss its outcomes and indications. Right TKA using the NexGen Legacy Constrained Condylar Knee implant was performed in a 62-year-old man with neuropathic arthropathy in multiple joints with clinical symptoms, particularly in the right knee. Seven years post-operation, the American Knee Society Score-knee and -function, which represent knee function and activities of daily living on a scale of 100 points, were significantly improved compared with preoperative values, from 30 to 99 points and 0 to 60 points, respectively. Indications for arthroplasty for neuropathic arthropathy should be carefully considered in each individual case. In this case, the patient had neuropathic arthropathy in multiple joints; however, TKA was performed because recovery of function in the right knee was expected to significantly improve the patient's activities of daily living, and a good mid-term clinical outcome was achieved. Therefore, indications for arthroplasty should be considered in patients with systemic neuropathic arthropathy such as leprosy, and with accurate assessment and appropriate implant selection, good long-term outcomes may be expected.

Overview and Current Advances in Dapsone Hypersensitivity Syndrome.

PURPOSE OF REVIEW: As a sulfone antibacterial agent, dapsone has been widely used to treat leprosy. Moreover, dapsone is also used in many immune diseases such as herpetic dermatitis because of its anti-inflammatory and immunomodulatory effects. However, dapsone can cause several adverse effects, the most serious being dapsone hypersensitivity syndrome. Dapsone hypersensitivity syndrome is characterized by a triad of eruptions, fever, and organ involvement, which limits the application of dapsone to some extent. RECENT FINDINGS: In this article, we review current research about the interaction model between HLA-B*13:01, dapsone, and specific TCR in dapsone-induced drug hypersensitivity. In addition to the proposed mechanisms, we also discussed clinical features, treatment progress, prevalence, and prevention of dapsone hypersensitivity syndrome. These studies reveal the pathogenesis, clinical features, and prevalence from the perspectives of genetic susceptibility and innate and adaptive immunity in dapsone hypersensitivity syndrome, thereby guiding clinicians on how to diagnose, prevent, and treat dapsone hypersensitivity syndrome.

Exploration of Neurofilament Light Chain and Nerve Ultrasound in Leprotic Neuropathy.

OBJECTIVES: To explore neurofilament light chain (NfL) levels in leprotic neuropathy compared to controls, and to determine if the changes correlate with ultrasonographic nerve findings. METHODS: Individuals with leprosy with signs or symptoms suggestive of peripheral nerve involvement were recruited. They were evaluated by clinical examination, functional scores, laboratory assessments (including NfL), nerve conduction studies (NCS), and ultrasound. Ultrasound was conducted in bilateral median, ulnar, tibial, fibular, sural, and vagus nerves as well as cervical roots 5 and 6. Results were compared to age, sex, and body mass index matched healthy controls. RESULTS: A total of 320 nerves from 20 patients and 480 nerves from 30 controls were evaluated. NfL was significantly elevated in those with leprosy with a mean and standard deviation of 7.50 + 2.83 compared with 3.42 + 1.18 in controls (P < .001). Ultrasound showed focal enlargement of the nerves, particularly at entrapment sites. Additionally, there were noticeable changes in neural Doppler signal, echogenicity, and epineural thickness among the measured nerve sites. NfL levels in those with leprosy correlated closely with nerve cross-sectional area at all sites (P < .05). Functional and clinical assessment scores correlated with NfL and sonographic cross-sectional area as well (P ≤ .05). CONCLUSIONS: NfL is elevated in leprotic neuropathy. Ultrasound showed specific morphological changes in individuals with leprosy, and nerve enlargement correlated with NfL levels. Thus, both modalities may be useful for the diagnosis, prognosis, and disease monitoring in those with leprotic neuropathy, and further investigations are warranted.
