Participatory development of a community mental wellbeing support package for people affected by skin neglected tropical diseases in the Kasai province, Democratic Republic of Congo.

BACKGROUND: Skin neglected tropical diseases (NTDs) produce signs and symptoms that are often physically challenging, stigmatizing and have a negative impact on the mental wellbeing of people affected. In the Democratic Republic of Congo (DRC), little is known about the mental wellbeing experiences of people affected by skin NTDs and support is lacking. We collaborated with ongoing NTD programs, the Ministry of Health and people affected to evidence experiences and opportunities for change and co-developed a mental wellbeing support package for people affected and local health system actors. METHODS: This implementation research study used the photovoice method alongside key-informant interviews to evidence mental wellbeing challenges in people affected by skin NTDs and explore opportunities for change. These were used to co-develop a skin NTD mental wellbeing support package with people affected, community members and local health system actors through a participatory workshop. RESULTS: Stigma, discrimination, decreased livelihoods and mental wellbeing challenges were evidenced by people affected by skin NTDs, their communities and health system actors. Participants identified and co-established community-led peer support groups, strengthened with basic knowledge on psychosocial support, and income-generating or recreational initiatives to support mental wellbeing of people affected by skin NTDs. CONCLUSIONS: Co-developing a support package with persons affected, community members and health system actors is a step towards holistic care for people affected by skin NTDs and promotes uptake and ownership of intervention components. CONTEXTE: Les maladies tropicales négligées (MTN) cutanées produisent des signes et des symptômes qui sont souvent difficiles à supporter physiquement, ils sont également stigmatisants et ont un impact négatif sur le bien-être mental des personnes touchées. En République Démocratique du Congo (RDC), on sait peu de choses sur le bien-être mental des personnes atteintes de MTN cutanées, et le soutien fait défaut. Nous avons collaboré avec les programmes de lutte contre les MTN en cours, le ministère de la santé et les personnes touchées pour mettre en évidence les expériences et les possibilités de changement, et nous avons élaboré un programme de soutien au bien-être mental pour les personnes touchées et les acteurs du système de santé local. MÉTHODES UTILISÉES: Cette étude de recherche sur la mise en œuvre a utilisé la méthode photovoice, ainsi que des entretiens avec des informateurs clés, afin de mettre en évidence les problèmes de bien-être mental des personnes touchées par les MNT cutanées. Ces éléments ont été utilisés pour élaborer un programme de soutien au bien-être mental des MNT cutanées avec les personnes concernées, les membres de la communauté et les acteurs du système de santé local dans le cadre d'un atelier participatif. RÉSULTATS: La stigmatisation, la discrimination, la diminution des moyens de subsistance et les problèmes de bien-être mental ont été mis en évidence par les personnes atteintes de MTN cutanées, leurs communautés et les acteurs du système de santé. Les participants ont identifié et mis en place des groupes communautaires de soutien par les pairs, renforcés par des connaissances de base en matière de soutien psychosocial, et des initiatives génératrices de revenus/récréatives pour soutenir le bien-être mental des personnes touchées par les MTN cutanées. CONCLUSIONS: L'élaboration d'un ensemble de mesures de soutien en collaboration avec les personnes concernées, les membres de la communauté et les acteurs du système de santé, constitue une étape vers une prise en charge holistique des personnes atteintes de MNT cutanées et favorise l'adoption et l'appropriation des composantes de l'intervention. ANTECEDENTES: Las enfermedades tropicales desatendidas (ETDs) cutáneas producen signos y síntomas que a menudo suponen un reto físico, estigmatizan y tienen un impacto negativo en el bienestar mental de las personas afectadas. En la República Democrática del Congo (RDC), se sabe poco sobre las experiencias de bienestar mental de las personas afectadas por ETDs cutáneas, y falta apoyo. Colaboramos con los programas en curso sobre las ETDs, el Ministerio de Sanidad y las personas afectadas para poner de manifiesto las experiencias y las oportunidades de cambio, y desarrollamos de manera conjunta un paquete de apoyo al bienestar mental para las personas afectadas y los agentes del sistema sanitario local. MÉTODOS: Este estudio de investigación utilizó el método fotovoz, junto con entrevistas a informantes clave, para poner de manifiesto los desafíos de bienestar mental de las personas afectadas por ETDs cutáneas y explorar las oportunidades de cambio. Estos datos se utilizaron para desarrollar un paquete de apoyo al bienestar mental de manera conjunta con las personas afectadas por las ETDs cutáneas, los miembros de la comunidad y los actores del sistema sanitario local a través de un taller participativo. RESULTADOS: El estigma, la discriminación, la disminución de los medios de subsistencia y los problemas de bienestar mental fueron evidenciados por las personas afectadas por ETD cutáneas, sus comunidades y los agentes del sistema sanitario. Los participantes identificaron y establecieron conjuntamente grupos de apoyo entre pares dirigidos por la comunidad, fortalecidos con conocimientos básicos sobre apoyo psicosocial e iniciativasrecreativas y generadoras de ingresos para apoyar el bienestar mental de las personas afectadas por las ETD cutáneas. CONCLUSIÓNS: El desarrollo conjunto de un paquete de medidas de apoyo con las personas afectadas, los miembros de la comunidad y los actores del sistema sanitario es un paso hacia la atención holística de las personas afectadas por las NTDs a y promueve la adopción y apropiación de los componentes de la intervención.

Stigma, depression and quality of life among people affected by neglected tropical diseases in Nepal.

BACKGROUND: Stigma and poor mental health are important factors influencing the quality of life (QOL) of people with neglected tropical diseases (NTDs). This study examines the relationship between stigma, depression and QOL among people affected by leprosy and lymphatic filariasis (LF) in Nepal. METHODS: A cross-sectional community-based survey was conducted among 102 NTD-affected persons (70 leprosy and 32 LF) using interview-administered questionnaires measuring the level of stigma (5-QSI-AP), symptoms of depression (PHQ-9) and QOL (WHOQOL-8). Three different regression models were developed, each using the ordinary least squares and Poisson regression to evaluate the association between stigma and QOL, depression and QOL, and stigma and depression. RESULTS: The mean scores were 21.8±4.4 for QOL, 6.6±5.6 for depression and 3.0±2.8 for stigma. Almost 17% reported the prevalence of depression symptoms. Both stigma (ß=-0.65, p<0.001) and depression (ß=-0.32, p<0.001) were associated with lower scores for QOL, while there was a significant positive relationship between stigma and depression (ß=0.92, p<0.001). Similar results were obtained from the Poisson regression models. CONCLUSIONS: The study showed a considerable burden of depression, stigma and poor QOL among study participants with leprosy and LF in Nepal. A holistic package of care that addresses the physical, mental and psychological well-being of people with NTD is required. CONTEXTE: La stigmatisation et la mauvaise santé mentale sont des facteurs importants qui influencent la qualité de vie des personnes atteintes de maladies tropicales négligées (MTN). Cette étude examine la relation entre la stigmatisation, la dépression et la qualité de vie chez les personnes atteintes de lèpre et de filariose lymphatique au Népal. MÉTHODES UTILISÉES: Une enquête communautaire transversale a été menée auprès de 102 personnes atteintes de MTN (70 de la lèpre et 32 de la filariose lymphatique) à l'aide de questionnaires administrés par entretien mesurant le niveau de stigmatisation (5-QSI-AP), les symptômes de dépression (PHQ-9) et la qualité de vie (WHOQOL-8). Trois modèles de régression différents ont été développés, chacun utilisant les moindres carrés ordinaires et la régression de Poisson pour évaluer l'association entre : (i) la stigmatisation et la QV; (ii) la dépression et la QV; et (iii) la stigmatisation et la dépression. RÉSULTATS: Les scores moyens étaient de 21,8±4,4 pour la QV, 6,6±5,6 pour la dépression, et 3,0±2,8 pour la stigmatisation. Près de 17% des personnes interrogées ont signalé la prévalence de symptômes dépressifs. La stigmatisation (ß = -0,65, p<0 001) et la dépression (ß = -0,32, p<0 001) ont été associées à des scores plus faibles pour la qualité de vie, tandis qu'il existait une relation positive significative entre la stigmatisation et la dépression (ß = 0,92, p<0 001). Des résultats similaires ont été obtenus à partir des modèles de régression de Poisson. CONCLUSIONS: L'étude a montré une incidence importante de dépression, de stigmatisation et d'une mauvaise qualité de vie parmi les participants atteints de lèpre et de FL au Népal. Il convient donc de mettre en place un ensemble de soins holistiques pour ces patients qui prendrait en compte le bien-être physique, mental et psychologique des personnes atteintes de MTN. ANTECEDENTES: La estigmatización y la mala salud mental son factores importantes que influyen en la calidad de vida de las personas con enfermedades tropicales desatendidas. las personas con enfermedades tropicales desatendidas (ETD). Este estudio examina la relación entre el estigma, la depresión y la CdV entre las personas afectadas por lepra y lepra y la filariasis linfática en Nepal. MÉTODOS: Se realizó una encuesta comunitaria transversal entre 102 personas afectadas por ETD (70 de lepra y 32 de filariasis linfática) utilizando cuestionarios entrevistas para medir el nivel de estigma (5-QSI-AP), los síntomas de depresión (PHQ- 9) y la CdV (OMS- 9). 9) y la calidad de vida (WHOQOL-8). Se desarrollaron tres modelos de regresión diferentes regresión de Poisson para evaluar la asociación entre: (i) el estigma y (ii) la depresión. entre: (i) estigma y CdV; (ii) depresión y CdV; y (iii) estigma y depresión. RESULTADOS: Las puntuaciones medias fueron 21,8±4,4 para la CdV, 6,6±5,6 para la depresión y 3,0±2,8 para el estigma. Casi el 17% informó de la prevalencia de síntomas de depresión. Tanto el estigma (ß = -0,65, p<0 001), como la depresión (ß = -0,32, p<0 001) se asociaron con puntuaciones más bajas para la CdV, mientras que hubo una relación positiva significativa entre el estigma y la depresión (ß = 0,92, p<0 001). Se obtuvieron resultados similares en los modelos de regresión de Poisson. CONCLUSIONES: El estudio mostró una carga considerable de depresión, estigma y mala CdV entre los participantes del estudio con lepra y FL en Nepal. Se requiere un paquete holístico de atención que aborde el bienestar físico, mental y psicológico de las personas con ETD.

Coverage of preventive measures and surveillance for neglected tropical diseases in hard-to-reach communities in Ghana.

BACKGROUND: Neglected tropical diseases (NTDs) are a major public health burden which mainly affects poor populations living in tropical environments and hard-to-reach areas. The study sought to examine coverage of preventive efforts, and case surveillance for NTDs in hard-to-reach communities in Ghana. METHODS: The study investigated treatment efforts for lymphatic filariasis (LF), and onchocerciasis and schistosomiasis/soil transmitted helminths (SCH/STH) at household level, in difficult-to-access communities in Ghana. A total of 621 households were sampled from 6 communities in the Western, Oti and Greater Accra regions. RESULTS: Over 95% of the households surveyed were covered under mass drug administration (MDA) campaigns for lymphatic filariasis (LF) and onchocerciasis. More than 80% of households had received at least two visits by community drug distributors under the MDA campaigns in the last two years preceding the study. In addition, over 90% of households in the LF and onchocerciasis endemic communities had at least one member using anthelminthic medications under the MDA campaigns in the 12 months preceding the study. However, households where no member had taken anthelminthic medications in 12 months preceding the study were over 6 times likely to have someone in the household with LF. CONCLUSIONS: This study determined that SCH/STH, LF and onchocerciasis are of serious public health concern in some communities in Ghana. There is an urgent need for holistic practical disease control plan involving both financial and community support to ensure total control of NTDs in difficult-to-access communities is achieved.

Broadening the research landscape in the field of snakebite envenoming: Towards a holistic perspective.

Snakebite envenoming (SBE) is a neglected tropical disease that kills and maims hundreds of thousands of people yearly, particularly in impoverished rural settings of the Global South. Understanding the complexity of SBE and tackling this disease demands a transdisciplinary, One Health approach. There is a long-standing research tradition on SBE in toxinology and human medicine. In contrast, other disciplines, such as veterinary medicine or social sciences, still need to be better developed in this field, especially in countries with a high incidence of SBE. Broadening the disciplinary landscape, connecting various research approaches, methods, and data across disciplines and sectors, and engaging with communities affected by SBE in implementing evidence-based solutions are needed. This review summarizes areas that require strengthening to better understand the complexity of SBE and to generate a robust body of knowledge to be translated into effective public health interventions.

Assessing the cost-effectiveness of integrated case management of Neglected Tropical Diseases in Liberia.

BACKGROUND: In 2017, Liberia became one of the first countries in the African region to develop and implement a national strategy for integrated case management of Neglected Tropical Diseases (CM-NTDs), specifically Buruli ulcer, leprosy, lymphatic filariasis morbidities, and yaws. Implementing this plan moves the NTD program from many countries' fragmented (vertical) disease management. This study explores to what extent an integrated approach offers a cost-effective investment for national health systems. METHODS: This study is a mixed-method economic evaluation that explores the cost-effectiveness of the integrated CM-NTDs approach compared to the fragmented (vertical) disease management. Primary data were collected from two integrated intervention counties and two non-intervention counties to determine the relative cost-effectiveness of the integrated program model vs. fragmented (vertical) care. Data was sourced from the NTDs program annual budgets and financial reports for integrated CM-NTDs and Mass Drug Administration (MDA) to determine cost drivers and effectiveness. RESULTS: The total cost incurred by the integrated CM-NTD approach from 2017 to 2019 was US$ 789,856.30, with the highest percentage of costs for program staffing and motivation (41.8%), followed by operating costs (24.8%). In the two counties implementing fragmented (vertical) disease management, approximately US$ 325,000 was spent on the diagnosis of 84 persons and the treatment of twenty-four persons suffering from NTDs. While 2.5 times as much was spent in integrated counties, 9-10 times more patients were diagnosed and treated. CONCLUSIONS: The cost of a patient being diagnosed under the fragmented (vertical) implementation is five times higher than integrated CM-NTDs, and providing treatment is ten times as costly. Findings indicate that the integrated CM-NTDs strategy has achieved its primary objective of improved access to NTD services. The success of implementing an integrated CM-NTDs approach in Liberia, presented in this paper, demonstrates that NTD integration is a cost-minimizing solution.

A health-systems journey towards more people-centred care: lessons from neglected tropical disease programme integration in Liberia.

BACKGROUND: Neglected tropical diseases (NTDs) are associated with high levels of morbidity and disability as a result of stigma and social exclusion. To date, the management of NTDs has been largely biomedical. Consequently, ongoing policy and programme reform within the NTD community is demanding the development of more holistic disease management, disability and inclusion (DMDI) approaches. Simultaneously, integrated, people-centred health systems are increasingly viewed as essential to ensure the efficient, effective and sustainable attainment of Universal Health Coverage. Currently, there has been minimal consideration of the extent to which the development of holistic DMDI strategies are aligned to and can support the development of people-centred health systems. The Liberian NTD programme is at the forefront of trying to establish a more integrated, person-centred approach to the management of NTDs and provides a unique learning site for health systems decision makers to consider how shifts in vertical programme delivery can support overarching systems strengthening efforts that are designed to promote the attainment of health equity. METHODS: We use a qualitative case study approach to explore how policy and programme reform of the NTD programme in Liberia supports systems change to enable the development of integrated people-centred services. RESULTS: A cumulation of factors, catalysed by the shock to the health system presented by the Ebola epidemic, created a window of opportunity for policy change. However, programmatic change aimed at achieving person-centred practice was more challenging. Deep reliance on donor funding for health service delivery in Liberia limits the availability of flexible funding, and the ongoing funding prioritization towards specific disease conditions limits flexibility in health systems design that can shape more person-centred care. CONCLUSION: Sheikh et al.'s four key aspects of people centred health systems, that is, (1) putting peoples voices and needs first; (2) people centredness in service delivery; (3) relationships matter: health systems as social institutions; and (4) values drive people centred health systems, enable the illumination of varying push and pull factors that can facilitate or hinder the alignment of DMDI interventions with the development of people-centred health systems to support disease programme integration and the attainment of health equity.

A holistic approach to well-being and neglected tropical diseases: evaluating the impact of community-led support groups in Nigeria using community-based participatory research.

BACKGROUND: Neglected tropical diseases (NTDs) affect around 1 billion people, many living in the poorest parts of the world. NTDs often lead to serious long-term physical impairments. Stigma, disability, poverty and social isolation interact, resulting in poor quality of life and significant psychosocial impacts. The holistic health and psychosocial needs of persons affected by NTDs are often overlooked in integrated NTD programme design and research. Furthermore, the viewpoints of persons affected are often absent and spaces for empowerment and advocacy are limited. METHODS: Using a community-based participatory research design, our study partnered with persons affected and caregivers as co-researchers to address this gap. Through the process, we co-designed and implemented community-based support groups in Kaduna and Kwara, Nigeria, where NTDs are endemic. This paper utilises photovoice with support group facilitators (persons affected); participant observation of group meetings; rapid micronarratives with support group members; and key informant interviews with programme implementers at the state and local government area levels to explore the impact of the support groups from the perspective of people affected by NTDs and other health system actors. RESULTS: Perceived impacts of the support groups included a sense of ownership and empowerment, stigma reduction, improved self-esteem, improved health knowledge and health outcomes and capacity strengthening through vocational training. CONCLUSIONS: Support groups, as community spaces of healing, offer a low-cost holistic intervention for chronic disease and disability.

Exploring the well-being of people affected by skin NTDs in Kaduna and Kwara States, Nigeria: a photovoice and scoping review study.

People affected by skin neglected tropical diseases (NTDs) grapple with both physical and emotional reactions that compromise their health and well-being. Multiple studies with people affected by skin NTDs have shown high levels of poor mental well-being using self-report questionnaires or psychological measures. However, few have provided in-depth documentation of lived experiences from the perspective of affected persons and there is limited consideration of how their viewpoints can be used to shape intervention design. This article draws together findings from an international scoping review and a photovoice study conducted in Kaduna and Kwara States, Nigeria. Our combined analysis, which situates the lived realities of people affected by skin NTDs within the existing evidence base, was used to inform the design of a subsequent well-being intervention. Using Meyer's (2003) minority stress model, we have illustrated that there is a synergistic relationship between mental health, chronic morbidity and disability from skin NTDs. This relationship results from a complex interplay of factors including pain and discomfort and a reduced ability to function and participate in areas such as livelihoods, food provision and education. Stigma and discrimination act as a catalyst for these functional limitations and participation restrictions, resulting in feelings of being useless, broken, shame and sadness. The critical role of participatory methods in our study emphasises how people affected by skin NTDs have multiple coping mechanisms that can be galvanised in the provision of holistic NTD care. We recommend that NTD programmes should strengthen relationships with affected persons to identify pre-existing support platforms that can be used to support the emotional and physical health and well-being of affected persons. Working with affected persons and community actors to strengthen necessary intersectoral approaches is a first step in designing and delivering such holistic care.

Global Health Impact: A Model to Alleviate the Burden and Expand Access to Treatment of Neglected Tropical Diseases.

Neglected tropical diseases (NTDs) receive relatively little research and development but have a tremendous impact on lifespan and livelihood. Here, we use existing data on the need for drugs, their efficacy, and their treatment percentages to estimate the impacts of various regimens on the global burden of several NTDs: schistosomiasis, onchocerciasis, lymphatic filariasis, and three soil-transmitted helminths (STHs) over time. For an interactive visualization of our models' results, see https://www.global-health-impact.org/. In 2015, our NTD models estimate that treatment averted 2,778,131.78 disability-adjusted life years (DALYs). Together, treatments targeting STHs together averted 51.05% of the DALYs averted from all NTD treatments, whereas schistosomiasis, lymphatic filariasis, and onchocerciasis medicines averted 40.21%, 7.56%, and 1.18%, respectively. Our models highlight the importance of focusing not just on the burden of these diseases but also on their alleviation in the effort to expand access to treatment.

Small molecules containing chalcogen elements (S, Se, Te) as new warhead to fight neglected tropical diseases.

Neglected tropical diseases (NTDs) encompass a group of infectious diseases with a protozoan etiology, high incidence, and prevalence in developing countries. As a result, economic factors constitute one of the main obstacles to their management. Endemic countries have high levels of poverty, deprivation and marginalization which affect patients and limit their access to proper medical care. As a matter of fact, statistics remain uncollected in some affected areas due to non-reporting cases. World Health Organization and other organizations proposed a plan for the eradication and control of the vector, although many of these plans were halted by the COVID-19 pandemic. Despite of the available drugs to treat these pathologies, it exists a lack of effectiveness against several parasite strains. Treatment protocols for diseases such as American trypanosomiasis (Chagas disease), leishmaniasis, and human African trypanosomiasis (HAT) have not achieved the desired results. Unfortunately, these drugs present limitations such as side effects, toxicity, teratogenicity, renal, and hepatic impairment, as well as high costs that have hindered the control and eradication of these diseases. This review focuses on the analysis of a collection of scientific shreds of evidence with the aim of identifying novel chalcogen-derived molecules with biological activity against Chagas disease, leishmaniasis and HAT. Compounds illustrated in each figure share the distinction of containing at least one chalcogen element. Sulfur (S), selenium (Se), and tellurium (Te) have been grouped and analyzed in accordance with their design strategy, chemical synthesis process and biological activity. After an exhaustive revision of the related literature on S, Se, and Te compounds, 183 compounds presenting excellent biological performance were gathered against the different causative agents of CD, leishmaniasis and HAT.

SUPPLEMENT INDIVIDUAL ARTICLES: Update on Truncal Acne: A Review of Treatments for a Neglected Disease and the Re-Emergence of Tazarotene.

Acne vulgaris of the trunk carries with it a major psychosocial impact and an unmet need for adequate management. Approximately 50% of patients with facial acne also exhibit involvement of the back, chest, and/or upper arms. The trunk poses a therapeutic challenge given its occlusion by clothing, the tendency for mechanical rubbing, a sebum physiology that differs from the face, as well as the fact that there is a large surface area for topical therapies to cover. Furthermore, truncal acne is underreported for a variety of reasons such as cultural barriers, sentiments of embarrassment, and prioritization of facial acne. To date, few medications have been studied specifically for truncal acne. In this article, an updated review of truncal acne and available therapies is provided. The most recent evidence for tazarotene, a third-generation retinoid previously approved for psoriasis and facial acne vulgaris over two decades ago, is also reviewed and compared to trifarotene, a fourth-generation retinoid that is the only approved tropical retinoid for both facial and truncal acne.

Scurvy in children - A neglected disease?

BACKGROUND: The incidences of pediatric scurvy has decreased substantially, particularly in developed countries, but there are still reports of it from developing countries. Unusual manifestations have led to delays in diagnosis and treatment. Nevertheless, there are few publications regarding misdiagnosis of scurvy. The objective is to determine dietary factors, clinical manifestations, laboratory and radiologic findings, treatment, and outcomes of scurvy cases. The occurrence of misdiagnosis and its associated factors are also explored. METHOD: The medical records of 0-18 year-old children from 2003 to 2016, diagnosed with scurvy, were included and reviewed. Clinical data, and data regarding feeding history, nutritional status, laboratory and radiologic findings, and misdiagnosis were collected. Univariate and logistic regression analysis were used for identification of the independent associated factors. RESULTS: The study consisted of 106 children. The boys-to-girls ratio was 2.2:1, and their mean age was 44.65 months ± 30.50 months. The common manifestations were refusal to walk, tenderness, and swelling at the lower extremities. Four participants had unusual manifestations including proptosis and scalp hematoma. Low serum vitamin C level and abnormal radiologic findings were detected in most patients. All of them fully recovered after receiving vitamin C supplementation. Misdiagnosis was identified in 74 cases (69%). Logistic regression analysis revealed that temperature higher than or equal to 38 °C, participants aged 3 years or below, and swelling at lower extremities were independently associated with misdiagnosis (adjusted OR 5.91, 3.78, and 3.56 respectively). CONCLUSIONS: Scurvy still exists, and misdiagnosis often occurs. Taking a careful medical history and conducting a physical examination are still the best way to diagnose scurvy.

Directrices para el tratamiento de las leishmaniasis en la región de las américas - 2 ed / Guidelines for the treatment of leishmaniasis in the region of the Americas - 2 ed

Las leishmaniasis son enfermedades infecciosas desatendidas de gran importancia en la Región de las Américas debido a su morbilidad, mortalidad y amplia distribución geográfica. De las tres formas clínicas principales, la cutánea es la más común y la visceral es la forma más grave, ya que puede causar la muerte de hasta 90% de las personas que no reciban tratamiento. En el 2013, la Organización Panamericana de la Salud (OPS) elaboró recomendaciones para el tratamiento de las leishmaniasis en la Región de las Américas utilizando la metodología de clasificación de la valoración, la elaboración y la evaluación de las recomendaciones (GRADE, por su sigla en inglés). No obstante, dada la evidencia acumulada desde entonces, se hizo necesario revisar esas recomendaciones. En esta segunda edición se presentan las recomendaciones actualizadas sobre el tratamiento de las leishmaniasis, y se detallan los esquemas y los criterios de indicación del tratamiento en el contexto regional. Estas directrices presentan modificaciones sustanciales con respecto a la primera edición. En el caso de la leishmaniasis cutánea, se ha eliminado el ketoconazol de las opciones terapéuticas, el número de especies de Leishmania para las que hay evidencia sólida de la eficacia de la miltefosina ha aumentado de dos a cuatro y la recomendación de administrar antimoniales intralesionales ahora es fuerte. Con respecto a la leishmaniasis mucosa, se incluye una recomendación fuerte sobre el uso de antimoniales pentavalentes con o sin pentoxifilina oral. Por lo que respecta a la leishmaniasis visceral, la recomendación fuerte sobre el uso de antimoniales pentavalentes y desoxicolato de anfotericina B ahora es condicional. También hay evidencia contundente en contra del uso de miltefosina en pacientes con leishmaniasis causada por Leishmania infantum. Otros cambios importantes son el desglose de las recomendaciones según si se trata de pacientes adultos o pediátricos, la inclusión de las especies de Leishmania y, en el caso de los pacientes inmunocomprometidos, la introducción de una recomendación fuerte contra el uso de antimoniales pentavalentes. Esta segunda edición es una versión revisada de la publicación Leishmaniasis en las Américas: recomendaciones para el tratamiento: https://iris.paho.org/handle/10665.2/7704

Interventions for Neglected Tropical Diseases Among Children and Adolescents: A Meta-analysis.

BACKGROUND: Neglected tropical diseases (NTDs) are a group of communicable diseases affecting the poorest populations around the world. OBJECTIVE: To assess the effectiveness of interventions, including mass drug administration (MDA), water, sanitation, and hygiene (WASH), vector control, health education, and micronutrients supplementation, for NTDs among children and adolescents. METHODS: We conducted a literature search on the Cochrane Controlled Trials Register, Medline, and other databases until December 2020. We included randomized controlled trials and quasi-experimental studies conducted among children and adolescents. Two authors independently screened studies for relevance. Two authors independently extracted data, assessed the risk of bias, performed metaanalysis, and rated the quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation. RESULTS: We included 155 studies (231 articles) involving 262 299 participants. For soil-transmitted helminthiasis, MDA may reduce the prevalence of Ascaris, Trichuris, and hookworm by 58%, 36%, and 57%, respectively. We are uncertain of the effect of health education, WASH, and iron supplementation on soil-transmitted helminthiasis prevalence. For Schistosomiasis, health education probably reduces the intensity and prevalence of S. mansoni, whereas micronutrient supplementation may reduce anemia prevalence and the infection intensity of S. hematobium compared with no supplementation. We are uncertain of the effect of MDA and vector control on Schistosomiasis outcomes. For trachoma, health education probably reduces the prevalence of active Trachoma, whereas we are uncertain of the effect of MDA, WASH, and vector control on Trachoma outcomes. There is limited data on the effectiveness of interventions for NTDs targeting children and adolescents. CONCLUSION: Future studies are needed to evaluate the relative effectiveness and cost-effectiveness of various interventions specifically targeting children and adolescents.

Practical teaching of pathophysiology to LAFFH at the IPD outpatient clinic of FMP/FASE: Historical Repor

Undergraduate students of UNIFASE/FMP, through the Academic League of Human Physiology and Pathophysiology (Liga Acadêmica de Fisiologia e FisiopatologiaHumana -LAFFH), participate in a supervised internship to outpatient at the Infectious and Parasitic DiseasesService of FMP/FASE, authorized by Clinical Direction (October 2018). Patients received conventional therapy in addition to complementary therapy with Homeopathy, for external use for cleaning skin lesions and modulating inflammatory responses, whose mechanisms of action are already described in the scientific literature and authorized by ANVISA. Aims: Make approach of undergraduate students to Homeopathic pathophysiology. Methodology: The supervised clinical internship of LAFFH students is in two service rooms with 6 students in each, based on prior appointment due to spontaneous demand, with medical records registered by the IPD outpatient service secretary. Outpatient clinical care addresses the pathophysiology and miasms of the symptoms and signs of neglected chronic parasitic diseases prevalent in our country, identified by anamnesis and physical examination. They are correlated to biological activities in plant chemistry classes, besides official homeopathic pharmacopoeia. So, it was adopted the external use of HUD Ledum palustre 6ch for the cleansing of skin lesions with torpid evolution at IPD. Results and discussion: Two patients with edemaand varicose ulcers were treated with the ointment offered. Edema extension which was +++/4+ to both patients diminished to +/4+ in 30 days of interval. Indeed, ulcers remained at the same shape and size, but their bases were cleaned, without purulence. Novel clinical sessions did not occur because of social distancing needed. Conclusion: It has been developed a positive perception among patients and students about the action of homeopathic remedies. The practical teaching activity initiated encourages students in clinical reasoning about complementary therapeutic association with Homeopathy for patients whose evolution is below the expected prognosis with conventional therapy. Project of clinical observation will be elaborated to research ethics committee.

"Using the same hand": The complex local perceptions of integrated one health based interventions in East Africa.

BACKGROUND: Neglected Tropical Diseases (NTDs) such as soil transmitted helminths (STH) and human rabies represent a significant burden to health in East Africa. Control and elimination remains extremely challenging, particularly in remote communities. Novel approaches, such as One Health based integrated interventions, are gaining prominence, yet there is more to be learned about the ways in which social determinants affect such programmes. METHODOLOGY: In 2015 a mixed method qualitative study was conducted in northern Tanzania to determine community perceptions towards integrated delivery of two distinct healthcare interventions: treatment of children for STH and dog vaccination for rabies. In order to assess the effectiveness of the integrated approach, villages were randomly allocated to one of three intervention arms: i) Arm A received integrated mass drug administration (MDA) for STH and mass dog rabies vaccination (MDRV); ii) Arm B received MDA only; iii) Arm C received MDRV only. PRINCIPLE FINDINGS: Integrated interventions were looked upon favourably by communities with respondents in all arms stating that they were more likely to either get their dogs vaccinated if child deworming was delivered at the same time and vice versa. Participants appreciated integrated interventions, due to time and cost savings and increased access to essential health care. Analysis of qualitative data allowed deeper exploration of responses, revealing why people appreciated these benefits as well as constraints and barriers to participation in integrated programmes. CONCLUSIONS/SIGNIFICANCE: An interdisciplinary One Health approach that incorporates qualitative social science can provide key insights into complex local perceptions for integrated health service delivery for STH and human rabies. This includes providing insights into how interventions can be improved while acknowledging and addressing critical issues around awareness, participation and underlying health disparities in remote pastoralist communities.

Significance of a neglected tropical disease: lessons from a paradigmatic case of 'success in translation'.

In a previous publication, I stressed the fundamental importance of research for improving health using as an example the control of Chagas disease in the Americas.(1) For that purpose, I analysed the major scientific breakthroughs and public health events from the 1909 discovery of Chagas disease and its causative pathogen, Trypanosoma cruzi, by Carlos Chagas,(2) through the successful control of its transmission by insect vectors in large regions of the Southern Cone countries in the 90s.(3) In the twenty years since that publication, Brazil and Latin American countries had to cope with a number of serious public health threats, old and new: (i) recrudescence of well-known diseases, such as dengue and yellow fever; (ii) emergence of viral diseases that had been restricted to other continents (Zika, Chikungunya); (iii) new epidemics (H1N1) or (iv) pandemics (COVID-19). Are there still some lessons from that success story against a neglected disease of the 90s that would be relevant today in the context of these recent challenges?

Screening the pandemic response box identified benzimidazole carbamates, Olorofim and ravuconazole as promising drug candidates for the treatment of eumycetoma.

Eumycetoma is a chronic subcutaneous neglected tropical disease that can be caused by more than 40 different fungal causative agents. The most common causative agents produce black grains and belong to the fungal orders Sordariales and Pleosporales. The current antifungal agents used to treat eumycetoma are itraconazole or terbinafine, however, their cure rates are low. To find novel drugs for eumycetoma, we screened 400 diverse drug-like molecules from the Pandemic Response Box against common eumycetoma causative agents as part of the Open Source Mycetoma initiative (MycetOS). 26 compounds were able to inhibit the growth of Madurella mycetomatis, Madurella pseudomycetomatis and Madurella tropicana, 26 compounds inhibited Falciformispora senegalensis and seven inhibited growth of Medicopsis romeroi in vitro. Four compounds were able to inhibit the growth of all five species of fungi tested. They are the benzimidazole carbamates fenbendazole and carbendazim, the 8-aminoquinolone derivative tafenoquine and MMV1578570. Minimal inhibitory concentrations were then determined for the compounds active against M. mycetomatis. Compounds showing potent activity in vitro were further tested in vivo. Fenbendazole, MMV1782387, ravuconazole and olorofim were able to significantly prolong Galleria mellonella larvae survival and are promising candidates to explore in mycetoma treatment and to also serve as scaffolds for medicinal chemistry optimisation in the search for novel antifungals to treat eumycetoma.

Drug associations as alternative and complementary therapy for neglected tropical diseases.

The present paper aims to establish different treatments for neglected tropical disease by a survey on drug conjugations and possible fixed-dose combinations (FDC) used to obtain alternative, safer and more effective treatments. The source databases used were Science Direct and PubMed/Medline, in the intervals between 2015 and 2021 with the drugs key-words or diseases, like "schistosomiasis", "praziquantel", "malaria", "artesunate", "Chagas' disease", "benznidazole", "filariasis", diethylcarbamazine", "ivermectin", " albendazole". 118 works were the object of intense analysis, other articles and documents were used to increase the quality of the studies, such as consensuses for harmonizing therapeutics and historical articles. As a result, an effective NTD control can be achieved when different public health approaches are combined with interventions guided by the epidemiology of each location and the availability of appropriate measures to detect, prevent and control disease. It was also possible to verify that the FDCs promote a simplification of the therapeutic regimen, which promotes better patient compliance and enables a reduction in the development of parasitic resistance, requiring further studies aimed at resistant strains, since the combined APIs usually act by different mechanisms or at different target sites. In addition to eliminating the process of developing a new drug based on the identification and validation of active compounds, which is a complex, long process and requires a strong long-term investment, other advantages that FDCs have are related to productive gain and gain from the industrial plant, which can favor and encourage the R&D of new FDCs not only for NTDs but also for other diseases that require the use of more than one drug.
