Basel: A Hotspot for Drug Discovery and Development Against Poverty-Related Diseases.

In discussion with Lukas Meier from the Swiss Tropical and Public Health Institute (Swiss TPH), Lutz Hegemann, Head of Novartis Global Health and Sustainability and Marcel Tanner, President of the Swiss Academies of Arts and Sciences, give their opinions on the changes that occurred in drug discovery and development for poverty-related diseases over the past 30 years. They emphasise the power of public-private partnerships and provide their points of views on what needs to be done in the future to ensure that the poorest of the poor also have access to important therapies.

Energy poverty, government expenditure, and institution factors in Sub-Saharan Africa countries: evidence based on a panel threshold model.

This article investigates the relationship between energy poverty and public expenditure for a sample of 20 Sub-Saharan countries over the period 2006-2020. This paper focuses on three research objectives. First is using a panel data threshold model with fixed effects proposed by Hansen (J Econom 93(2):345-368, 1999) to detect the presence of the nonlinear effect of public expenditure on energy poverty. Second, we try to explain the effect of public expenditure transmission channels on energy poverty. Third, we explore the impact of public expenditure on energy poverty considering the role of institution factors. Thus, our analysis approves the existence of a link between energy poverty and public expenditure with a threshold of about 17.65% of GDP. In addition, CO2 emissions can accelerate the growth of energy poverty in SSA countries. Indeed, the results show that in countries with high energy poverty, there is a bidirectional causal link between CO2 emissions and energy poverty. This would provide a better understanding of the relationship between public expenditure and energy poverty suggesting useful implications for policymakers in targeting sustainable energy.

The effect of conditional cash transfers on the control of neglected tropical disease: a systematic review.

BACKGROUND: Neglected tropical diseases (NTDs) are diseases of poverty and affect 1·5 billion people globally. Conditional cash transfer (CCTs) programmes alleviate poverty in many countries, potentially contributing to improved NTD outcomes. This systematic review examines the relationship between CCTs and screening, incidence, or treatment outcomes of NTDs. METHODS: In this systematic review we searched MEDLINE, Embase, Lilacs, EconLit, Global Health, and grey literature websites on Sept 17, 2020, with no date or language restrictions. Controlled quantitative studies including randomised controlled trials (RCTs) and observational studies evaluating CCT interventions in low-income and middle-income countries were included. Any outcome measures related to WHO's 20 diseases classified as NTDs were included. Studies from high-income countries were excluded. Two authors (AA and TH) extracted data from published studies and appraised risk of biases using the Risk of Bias in Non-Randomised Studies of Interventions and Risk of Bias 2 tools. Results were analysed narratively. This study is registered with PROSPERO, CRD42020202480. FINDINGS: From the search, 5165 records were identified; of these, 11 studies were eligible for inclusion covering four CCTs in Brazil, the Philippines, Mexico, and Zambia. Most studies were either RCTs or quasi-experimental studies and ten were assessed to be of moderate quality. Seven studies reported improved NTD outcomes associated with CCTs, in particular, reduced incidence of leprosy and increased uptake of deworming treatments. There was some evidence of greater benefit of CCTS in lower socioeconomic groups but subgroup analysis was scarce. Methodological weaknesses include self-reported outcomes, missing data, improper randomisation, and differences between CCT and comparator populations in observational studies. The available evidence is currently limited, covering a small proportion of CCTs and NTDs. INTERPRETATION: CCTs can be associated with improved NTD outcomes, and could be driven by both improvements in living standards from cash benefits and direct health effects from conditionalities related to health-care use. This evidence adds to the knowledge of health-improving effects from CCTs in poor and vulnerable populations. FUNDING: None.

A resilience building collaboration: A social identity empowerment approach to trauma management in leprosy-affected communities.

OBJECTIVES: Communities affected by leprosy encounter multiple traumas and adversities and are some of the poorest in the world. A diagnosis of leprosy can have catastrophic implications for peoples social, health, and economic circumstances. In this article, we describe a reciprocal collaboration with a nongovernmental organization (NGO) that supports people affected by leprosy, trauma, and adversity in rural Nepal. We offer a social identity-based empowerment approach for two reasons. We argue this approach is particularly suited to support those impacted by trauma and its psychological aftermath as those affected are disproportionately from disempowered and marginalized groups. Second, we know that people gain strength from others with whom they share experiences. METHOD: We offer longitudinal data (N = 71) to support this model of a mutually respectful, participatory, and collaborative approach with the Nepal Leprosy Trust (NLT), a social development NGO. RESULTS: Findings of mediation analysis highlight that where a traumatic experience is highly stigmatized and isolating there is value in a group-based, self-help approach that emphasizes empowerment. CONCLUSION: A group-based approach that focuses on increasing knowledge and collective social resources is empowering for those affected by leprosy and adversity, because these resources build resilience.

Undernutrition, food insecurity, and leprosy in North Gondar Zone, Ethiopia: A case-control study to identify infection risk factors associated with poverty.

BACKGROUND: Ethiopia has over 3,200 new cases of leprosy diagnosed every year. Prevention remains a challenge as transmission pathways are poorly understood. Susceptibility and disease manifestations are highly dependent on individual host-immune response. Nutritional deficiencies, such as protein-energy malnutrition, have been linked to reduced cell-mediated immunity, which in the case of leprosy, could lead to a higher chance of active leprosy and thus an increased reservoir of transmissible infection. METHODOLOGY/PRINCIPAL FINDINGS: Between June and August 2018, recently diagnosed patients with leprosy and individuals without known contact with cases were enrolled as controls in North Gondar regional health centers. Participants answered survey questions on biometric data, demographics, socioeconomic situation, and dietary habits. Descriptive statistics, univariate, and multivariate logisitic regression examined associations between undernutrition, specifically body mass index (BMI), middle upper arm circumference (MUAC), and leprosy. Eighty-one participants (40 cases of leprosy, 41 controls) were enrolled (75% male) with an average age of 38.6 years (SD 18.3). The majority of cases were multibacillary (MB) (90%). There was a high prevalence of undernutrition with 24 (29.6%) participants underweight (BMI <18.5) and 17 (21%) having a low MUAC. On multivariate analysis, underweight was significantly associated with leprosy (aOR = 9.25, 95% CI 2.77, 30.81). Also found to be associated with leprosy was cutting the size of meals/skipping meals (OR = 2.9, 95% CI 1.0, 8.32) or not having enough money for food (OR = 10, 95% CI 3.44 29.06). CONCLUSIONS/SIGNIFICANCE: The results suggest a strong association between leprosy and undernutrition, while also supporting the framework that food insecurity may lead to undernutrition that then could increase susceptibility to leprosy. In conclusion, this study highlights the need to study the interplay of undernutrition, food insecurity, and the manifestations of leprosy.

Looking for NTDs in the skin; an entry door for offering patient centered holistic care.

INTRODUCTION: The majority of neglected tropical diseases (NTDs) have established primary skin manifestations or associated clinical feature. Skin NTDs often result in physical impairment and disfigurement, which can lead to disability. Skin diseases have been proposed as an entry point for integrated NTDs control. However, the magnitude and overlap of skin NTDs is poorly understood. METHODOLOGY: An institution-based cross-sectional study was done using medical records of dermatology patients between July 2017 and June 2018 in a dermatology service in Northeast Ethiopia. A total of 661 patient records were selected using simple random sampling. RESULTS: A total of 656 complete records were included in analysis. Skin NTDs constituted 17.2% (n = 113) of the overall of skin diseases. Of skin NTDS, cutaneous leishmaniasis (n = 40; 35.4%), leprosy (n = 38; 33.6%), and scabies (n = 31; 27.4%) were the most common. Additionally, there were four cases of mycetoma. Of the non NTDs, poverty-related infections such as superficial fungal (n = 118; 21.1%) and bacterial (n = 33; 5.2%) infections were also frequent. Tinea capitis was the most common superficial fungal infections. Impetigo and cellulitis were the predominant bacterial infections. CONCLUSIONS: Skin NTDsand other poverty related skin infections were common at the dermatology service. Dermatological services could act as a good entry point for integrated management of skin NTDs. Future studies should assess how different preventive strategies like contact tracing, early diagnosis and mass drug administration can be integrated.

Comorbidities associated with non- healing of plantar ulcers in leprosy patients.

BACKGROUND: Non-healing plantar ulcers are one of the significant causes of disability in leprosy patients. Plantar ulcers often take months or years to heal, affecting the patient's quality of life. Presence of comorbid conditions in these patients can delay wound healing. The study aimed to evaluate the role of associated comorbid conditions as risk factors in ulcer healing. METHODOLOGY/PRINCIPAL FINDINGS: A total of 66 leprosy patients with plantar ulcers registered at LEPRA Society-Blue Peter Public Health and Research Center (BPHRC), Hyderabad, India from June 2018 to June 2019 were studied. Comprehensive clinical assessment was done, including screening for comorbid conditions and treated as per the recommended guidelines. About two-thirds of the participants were aged 50 and above, of which more than half were illiterates, and 93.5% were living below the poverty line. Majority of ulcers were seen on the forefoot; with the head of meta-tarsal bone 27 (41.6%) as the commonest site, followed by calcaneum 23 (38.3%) and great toe 10 (16.6%). Mean ulcer depth was 0.61 (0.57) cm, the area was 5.24 (6.73) cm2 and ulcer volume was 4.72 (14.33) cm3. Ulcer dimensions were significantly associated with low body mass index, hypertension and smoking. CONCLUSIONS/SIGNIFICANCE: Identifying the risk factors delaying wound healing and detailed assessment of ulcers are of profound importance to predict the outcome of plantar ulcers in leprosy patients. The study findings indicate the need for better policies by the leprosy control program for the comprehensive management of plantar ulcers.

Leprosy and social deprivation: Definition of priority areas in an endemic state Northeastern Brazil. / Hanseníase e carência social: definição de áreas prioritárias em estado endêmico do Nordeste brasileiro.

INTRODUCTION: Leprosy is a disease that reserves close relation with social and economic conditions. Brazil is the only country that has not yet reached the goal of eliminating the disease as a public health problem. OBJECTIVE: This study aimed to analyze social deprivation in the municipalities of Bahia and its relation with the detection of new cases of leprosy in the population. METHODS: It is an ecological study conducted in the state of Bahia, from 2001 to 2015. Variables analyzed: detection rate of new cases, social deprivation index (SDI) and Hansen's disease in children under 15 years of age. The SDI was built on four variables: socioeconomic performance index, per capita income, proportion of extremely poor, and household density. For spatial analysis, local empirical bayesian modeling and global and local Moran statistics were used. Statistical analysis used multivariate, spatial and logistic regression, odds ratio calculation and analysis of variance. RESULTS: Leprosy showed heterogeneous distribution in the state, with concentration in the north-west and south axis. 60.4% (n = 252) of the municipalities presented very low life conditions. An association was observed between living conditions and the detection of leprosy, with higher coefficients in the municipality group with better living conditions (p < 0.001). CONCLUSION: It was concluded that the worst conditions acted as an impediment to the diagnosis, while increasing the risk of illness. Good conditions have the opposite effect.

INTRODUÇÃO: A hanseníase é uma doença que guarda estreita relação com as condições sociais e econômicas. O Brasil é o único país que ainda não alcançou a meta de eliminação da doença como problema de saúde pública. OBJETIVO: Este trabalho teve como objetivo analisar a associação entre a carência social dos municípios baianos e a detecção de casos novos de hanseníase na população, como instrumento para a definição de áreas prioritárias para intervenção. METODOLOGIA: Trata-se de um estudo ecológico realizado no estado da Bahia, no período de 2001 a 2015. Variáveis analisadas: coeficiente de detecção casos novos, índice de carência social (ICS) e hanseníase em menores de 15 anos. O ICS foi construído com base em quatro variáveis: índice de performance socioeconômica, renda per capita, proporção de extremamente pobres e densidade domiciliar. Na análise espacial, foram utilizadas modelagem bayesiana empírica local e estatística de Moran global e local. Na análise estatística, foram empregados regressão multivariada, espacial e logística, cálculo do odds ratio e análise de variância. RESULTADOS: A hanseníase apresentou distribuição heterogênea no estado, com concentração no eixo norte-oeste e sul. Dos municípios, 60,4% (n = 252) apresentaram muito baixa condição de vida. Observou-se associação entre as condições de vida e a detecção da hanseníase, com maiores coeficientes no grupo de município com melhor condição de vida (p < 0,001). CONCLUSÃO: As piores condições atuaram como um impeditivo ao diagnóstico, ao mesmo tempo que ampliaram o risco de adoecimento. As boas condições possuem efeito inverso.

Patients help other patients: Qualitative study on a longstanding community cooperative to tackle leprosy in India.

BACKGROUND: Although leprosy is portrayed as a disappearing disease, leprosy affected persons in India are still suffering massively. Even further, nearly 60% of the world's newly detected cases are appearing from India alone. The problem has exacerbated due to the drastic decrease of global funding after India's official declaration of 'elimination', which did not foster the actual pain of patients beyond prevalence. Leprosy patients have hardships in their lives due to disabilities, stigma and poverty; thus, they require sustained, continuous care even after release from treatment. Yet, current interventions mostly have a vertical, short-term approach, not showing much progress in lightening the burden of leprosy. In contrast, Little Flower Hospital Community (LFHC) in India has been remarkably providing holistic care for thousands of leprosy patients for 35 years. However, there has not been any research conducted to uncover the underlying factors of this longstanding leprosy control model. Therefore, this research explores the in-depth contextual attributes of this hospital community that has been able to successfully provide sustainable care for a long time even without excessive external funds. METHODS AND FINDINGS: This qualitative research used a grounded theory approach, involving 28 in-depth interviews of 11 patients, 13 workers, and 4 board members from the hospital. The interview data were inductively analyzed to examine the contextual factors of the hospital's sustainability. Open coding, axial coding and selective coding were conducted, and Glaser's Six C's model was used to create a theoretical model of the sustainability of LFHC. The fundamental cause of the sustainability was the leprosy patients' strong craving for life with dignity, despite the isolation from the society. The desire resulted in a bottom-up formation of a 'consumer-provider cooperative', where patients mutually support each other with basic treatment learned from experience. The profits earned from the patients' occupational efforts such as dairy farming, cover the costs needed to manage the hospital community, which contributes to economical sustainability. Social sustainability was established through the holistic care including psychosocial, educational, medical, and residential support. The wholesome care socially rehabilitated the patients to be included in the society with satisfaction, social justice and social cohesion. The main limitation of this study is that this study cannot be generalized due to the nature of Grounded Theory based study. CONCLUSIONS: This study investigated the determinants that made LFHC sustainable, and the findings suggested the importance of forming a cooperative community and implementing social rehabilitation for sustainable leprosy control. More exploration on transferring this model to other leprosy colonies will have great impact in maintaining sustainable care for leprosy patients. Furthermore, this research may highlight the importance of sustainable development in policies targeting neglected tropical diseases beyond leprosy as well.

Assessing the Impact of the Twin Track Socio-Economic Intervention on Reducing Leprosy-Related Stigma in Cirebon District, Indonesia.

The consequences of leprosy go beyond the physical, social and psychological, as leprosy can drive persons affected and their families into poverty, stigmatization and disability. This paper describes the impact of a socio-economic development (SED) intervention that uses a twin-track approach (two micro-credit models) to reduce leprosy-related stigma in Cirebon District, Indonesia. A randomized-controlled mixed-methods study design was used to test the effectiveness of the SED intervention. Three scales were used to measure stigma and participation restrictions among 30 SED clients and 57 controls, 20 in-depth interviews with SED clients and seven Focus Group Discussions (FGDs) with key persons were held and 65 profiles of the clients were written up and analysed. The qualitative data shows the socio-economic status of 44 out of 65 SED clients (67%) improved. The median family income increased by 25%, more clients reported higher self-esteem, better interaction with neighbours and less stigma than before, although disclosure concerns remained an issue. The scales indicate a positive effect of the intervention on reducing stigma (e.g., Stigma Assessment and Reduction of Impact (SARI) stigma scale mean difference total score of pre and post assessment for SED clients versus the control group was 8.5 versus 5.6). A twin track socio-economic intervention, if embedded and integrated, can increase participation, and be constructive in reducing leprosy-related stigma.

A scoping review on the field validation and implementation of rapid diagnostic tests for vector-borne and other infectious diseases of poverty in urban areas.

BACKGROUND: Health personnel face challenges in diagnosing vector-borne and other diseases of poverty in urban settings. There is a need to know what rapid diagnostic technologies are available, have been properly assessed, and are being implemented to improve control of these diseases in the urban context. This paper characterizes evidence on the field validation and implementation in urban areas of rapid diagnostics for vector-borne diseases and other diseases of poverty. MAIN BODY: A scoping review was conducted. Peer-reviewed and grey literature were searched using terms describing the targeted infectious diseases, diagnostics evaluations, rapid tests, and urban setting. The review was limited to studies published between 2000 and 2016 in English, Spanish, French, and Portuguese. Inclusion and exclusion criteria were refined post hoc to identify relevant literature regardless of study design and geography. A total of 179 documents of the 7806 initially screened were included in the analysis. Malaria (n = 100) and tuberculosis (n = 47) accounted for the majority of studies that reported diagnostics performance, impact, and implementation outcomes. Fewer studies, assessing mainly performance, were identified for visceral leishmaniasis (n = 9), filariasis and leptospirosis (each n = 5), enteric fever and schistosomiasis (each n = 3), dengue and leprosy (each n = 2), and Chagas disease, human African trypanosomiasis, and cholera (each n = 1). Reported sensitivity of rapid tests was variable depending on several factors. Overall, specificities were high (> 80%), except for schistosomiasis and cholera. Impact and implementation outcomes, mainly acceptability and cost, followed by adoption, feasibility, and sustainability of rapid tests are being evaluated in the field. Challenges to implementing rapid tests range from cultural to technical and administrative issues. CONCLUSIONS: Rapid diagnostic tests for vector-borne and other diseases of poverty are being used in the urban context with demonstrated impact on case detection. However, most evidence comes from malaria rapid diagnostics, with variable results. While rapid tests for tuberculosis and visceral leishmaniasis require further implementation studies, more evidence on performance of current tests or development of new alternatives is needed for dengue, Chagas disease, filariasis, leptospirosis, enteric fever, human African trypanosomiasis, schistosomiasis and cholera.

Lepra en mujeres: estigma y dolor / No disponible

La lepra o enfermedad de Hansen es una enfermedad infecciosa crónica incapacitante. Esta enfermedad permanece en el olvido de la ciencia y de la investigación en el campo de la salud; las mujeres que la padecen sufren doblemente la exclusión, por su condición de enfermas y de mujeres. Ser mujer hará que tengan menos probabilidades que los hombres de ser diagnosticadas a tiempo, aumentando el riesgo de desarrollar una discapacidad de por vida. Lo que hace que se observe, dentro de la propia exclusión de la enfermedad, una triple discriminación en las mujeres y niñas enfermas de lepra, por su género, por las discapacidades que resultan de la enfermedad y por sufrir el impacto del estigma, lo que acentúa aún más su pobreza

Leprosy or Hansen's disease is a chronic disabling infectious disease. This disease remains in the oblivion of science and research in the field of health; women who suffer from it suffer double exclusion, because they are sick and women. Being a woman will make them less likely than men to be diagnosed early, increasing the risk of developing a disability for life. What makes observed, within the exclusion of the disease itself, a triple discrimination in women and girls suffering from leprosy, by their gender, by the disabilities that result from the disease and by suffering the impact of stigma, which it further accentuates their poverty

Socioeconomic benefit to individuals of achieving 2020 targets for four neglected tropical diseases controlled/eliminated by innovative and intensified disease management: Human African trypanosomiasis, leprosy, visceral leishmaniasis, Chagas disease.

BACKGROUND: The control or elimination of neglected tropical diseases (NTDs) has targets defined by the WHO for 2020, reinforced by the 2012 London Declaration. We estimated the economic impact to individuals of meeting these targets for human African trypanosomiasis, leprosy, visceral leishmaniasis and Chagas disease, NTDs controlled or eliminated by innovative and intensified disease management (IDM). METHODS: A systematic literature review identified information on productivity loss and out-of-pocket payments (OPPs) related to these NTDs, which were combined with projections of the number of people suffering from each NTD, country and year for 2011-2020 and 2021-2030. The ideal scenario in which the WHO's 2020 targets are met was compared with a counterfactual scenario that assumed the situation of 1990 stayed unaltered. Economic benefit equaled the difference between the two scenarios. Values are reported in 2005 US$, purchasing power parity-adjusted, discounted at 3% per annum from 2010. Probabilistic sensitivity analyses were used to quantify the degree of uncertainty around the base-case impact estimate. RESULTS: The total global productivity gained for the four IDM-NTDs was I$ 23.1 (I$ 15.9 -I$ 34.0) billion in 2011-2020 and I$ 35.9 (I$ 25.0 -I$ 51.9) billion in 2021-2030 (2.5th and 97.5th percentiles in brackets), corresponding to US$ 10.7 billion (US$ 7.4 -US$ 15.7) and US$ 16.6 billion (US$ 11.6 -US$ 24.0). Reduction in OPPs was I$ 14 billion (US$ 6.7 billion) and I$ 18 billion (US$ 10.4 billion) for the same periods. CONCLUSIONS: We faced important limitations to our work, such as finding no OPPs for leprosy. We had to combine limited data from various sources, heterogeneous background, and of variable quality. Nevertheless, based on conservative assumptions and subsequent uncertainty analyses, we estimate that the benefits of achieving the targets are considerable. Under plausible scenarios, the economic benefits far exceed the necessary investments by endemic country governments and their development partners. Given the higher frequency of NTDs among the poorest households, these investments represent good value for money in the effort to improve well-being, distribute the world's prosperity more equitably and reduce inequity.

Dietary diversity and poverty as risk factors for leprosy in Indonesia: A case-control study.

BACKGROUND: Poverty has long been considered a risk factor for leprosy and is related to nutritional deficiencies. In this study, we aim to investigate the association between poverty-related diet and nutrition with leprosy. METHODOLOGY/PRINCIPAL FINDINGS: In rural leprosy-endemic areas in Indonesia, we conducted a household-based case-control study using two controls for each case patient (100 recently diagnosed leprosy patients and 200 controls), matched for age and gender. All participants were interviewed to collect information on their demographics, socioeconomic situation, health, and diet. Body mass index, dietary diversity score, as well as anemia and iron micronutrient profiles were also obtained. By means of univariate, block-wise multivariate, and integrated logistic regression analyses, we calculated odds ratios between the variables and the occurrence of leprosy. Unstable income (odds ratio [OR], 5.67; 95% confidence interval [CI], 2.54-12.64; p = 0.000), anemia (OR, 4.01; 95% CI, 2.10-7.64; p = 0.000), and higher household food insecurity (OR, 1.13; 95% CI, 1.06-1.21; p = 0.000) are significantly associated with an increased risk of having leprosy. Meanwhile, higher education (OR, 0.34; 95% CI, 0.15-0.77; p = 0.009) and land ownership (OR, 0.39; 95% CI, 0.18-0.86; p = 0.019) have significant protective associations against leprosy. Although lower dietary diversity, lack of food stock, food shortage, low serum iron, and high ferritin were found more commonly in those with leprosy, the occurrence of leprosy was not significantly associated with iron deficiency (OR, 1.06; 95% CI, 0.10-11.37; p = 0.963). CONCLUSIONS/SIGNIFICANCE: Food poverty is an important risk factor for leprosy susceptibility, yet the mechanisms underlying this association other than nutrient deficiencies still need to be identified. With a stable incidence rate of leprosy despite the implementation of chemoprophylaxis and multidrug therapy, improving dietary diversity through food-based approaches should be initiated and directed toward high-prevalence villages. The possible underlying factors that link poverty to leprosy other than nutrient deficiencies also need to be identified.

Guidelines for management of rheumatic diseases in developing countries from basics to real-world situation: relevance, need, and processes for development.

Guidelines or recommendations help to provide uniform standards in medical practice. The development of guidelines requires adherence to pre-defined norms prescribed by different international organizations such as the European League against Rheumatism (EULAR). We searched Pubmed and LILACS to identify published papers in five major rheumatic diseases (rheumatoid arthritis, systemic lupus erythematosus, spondyloarthropathies, osteoarthritis, and scleroderma) from different countries based on their economic prosperity and could find a lack of published literature from most economically weaker regions. Similarly, published guidelines in these rheumatic diseases were sparse from Asia and Africa, which are economically developed to a lesser extent than other regions of the world. Considering differing economic realities driving patient care in different regions of the world, unique challenges in certain geographic areas such as musculoskeletal manifestations of infectious diseases like leprosy and tuberculosis, as well as distinct risk of malignancies and other comorbid conditions, National Rheumatology societies should work towards developing more guidelines for rheumatic diseases from regions such as Asia and Africa, while following strictly the prescribed norms for the same. With a paucity of guidelines for such regions currently, an alternative (although less preferable) suggestion would be that major international societies, whose guidelines are widely read and followed the world over, should consider inputs from experts from diverse regions of the world while developing these guidelines.

Doenças infecciosas e suas correlações com indicadores socioeconômicos e demográficos: estudo ecológico em diferentes estados brasileiros / Infectious diseases and their correlations with socioeconomic and demographic indicators: an ecological study in different Brazilian states

No Brasil, as doenças infecciosas têm apresentado importante evolução em seus perfis epidemiológicos, e a população tem sofrido grandes oscilações demográficas nas últimas décadas. A concentração demográfica em um contexto de pobreza pode estar associada à expansão de algumas doenças. Partindo desta hipótese, o presente estudo avaliou, em uma abordagem ecológica, alguns indicadores socioeconômicos e demográficos de 1895 municípios brasileiros que compõem os estados do Rio de Janeiro, Minas Gerais, Rio Grande do Sul, Goiás, Acre e Pernambuco, onde as unidades do estudo foram os municípios. O período avaliado foi entre os anos 2001 a 2012. Consideramos como variáveis explicativas o índice de desenvolvimento humano municipal (IDHM) o produto interno bruto per capita, a proporção de população vivendo em pobreza extrema e o coeficiente de Gini, também a incidência de infecção pelo HIV/AIDS nos municípios analisados para a tuberculose. Como variáveis resposta, consideramos as taxas de incidência anuais para tuberculose, hanseníase, sífilis congênita e dengue, além das taxas de mortalidade específicas para doença de Chagas. Aplicou-se a correlação de Spearman para as análises. Os resultados revelaram um padrão de maior acúmulo de riqueza e desenvolvimento nas cidades onde o IDHM se correlacionou positivamente com o PIB e o tamanho da população dos municípios

Também foi constatado menor proporção de pessoas vivendo em extrema pobreza nestas áreas, e uma tendência de forte urbanização das doenças infecciosas incluídas neste trabalho, com taxas de incidência aumentando ao longo da década analisada para estas cidades. Os resultados sugerem ainda que a concentração de renda, de infraestrutura e serviços, cria paradoxalmente condições para uma maior ocorrência de doenças infecciosas geralmente ligadas à pobreza com diferentes vias de transmissão, seja respiratória, sexual ou por vetores. Possivelmente os centros urbanos, por conterem aglomerados de moradias precárias e grande população carcerária, contribuem para este novo panorama epidemiológico das doenças aqui elencadas, embora apresentem melhores indicadores para qualidade de vida. De tal forma, que algumas infecções se apresentam como o novo desafio às políticas públicas de controle de doenças no ambiente urbano, como exemplo a sífilis congênita. Sugere-se então, abordagens e ações multidisciplinares voltadas para a prevenção da saúde da população em geral com foco na formação dos profissionais de saúde e educação. (AU)

Doenças transmissíveis e situação socioeconômica no Brasil: análise espacial

O presente estudo tem como objetivo descrever a distribuição espacial dos indicadores epidemiológicos das doenças transmissíveis relacionadas à pobreza nos municípios brasileiros, visando demarcar áreas geográficas com concentração de morbidades e condições socioeconômicas precárias para o direcionamento de ações integradas de políticas públicas de saúde e sociais. Trata-se de estudo ecológico descritivo com abordagem espacial, tendo como unidades de análise os municípios brasileiros. A partir de dados dos sistemas de informação do Ministério da Saúde (MS) e do Instituto Brasileiro de Geografia e Estatística (IBGE), foram calculados indicadores de incidência das seguintes doenças transmissíveis relacionadas à pobreza, segundo sua relevância para a saúde pública e disponibilidade de dados: tuberculose, hanseníase, leishmaniose tegumentar, leishmaniose visceral e malária.

Household costs of leprosy reactions (ENL) in rural India.

BACKGROUND: Erythema nodosum leprosum (ENL) is a common immune-mediated complication of lepromatous (LL) and borderline lepromatous (BL) leprosy. Most patients experience chronic or multiple acute ENL over many years during an economically active period of their lives. Understanding the economic burden of ENL is essential to provide effective patient support, yet this area has not been investigated. METHODS: Ninety-one patients with LL or BL leprosy attending a leprosy hospital in Purulia district of West Bengal, India, were interviewed using a structured questionnaire. Cases (n = 53) were identified as those who had one or more episodes of ENL within the last 3 years. Controls (n = 38) had LL or BL leprosy but no history of ENL. Data were collected on household income, direct and indirect costs, and coping strategies. FINDINGS: The total household cost was Rs 1543 per month or 27.9% (IQR 13.2-52.6) of monthly household income for cases, and Rs 237 per month or 4.9% (IQR 1.7-13.4) of monthly household income for controls. Indirect costs accounted for 65% of total household costs for cases. Direct costs accounted for the remaining 35% of household costs, and resulted almost entirely from treatment-seeking in the private sector. Total household costs exceeded 40% of household income for 37.7% of cases (n = 20) and 2.6% of controls (n = 1) [1 USD = 59 INR]. INTERPRETATION: Households affected by ENL face significant economic burden and are at risk of being pushed further into poverty. Health policy should acknowledge the importance of private sector provision and the significant contribution to total household costs of lost productivity (indirect cost). Further work is needed to explore this area and identify solutions.
