Over 200,000 new cases of leprosy are detected each year, of which approximately 7% are associated with grade-2 disabilities (G2Ds). For achieving leprosy elimination, one of the main challenges will be targeting higher risk groups within endemic communities. Nevertheless, the socioeconomic risk markers of leprosy remain poorly understood. To address this gap we systematically reviewed MEDLINE/PubMed, Embase, LILACS and Web of Science for original articles investigating the social determinants of leprosy in countries with > 1000 cases/year in at least five years between 2006 and 2016. Cohort, case-control, cross-sectional, and ecological studies were eligible for inclusion; qualitative studies, case reports, and reviews were excluded. Out of 1,534 non-duplicate records, 96 full-text articles were reviewed, and 39 met inclusion criteria. 17 were included in random-effects meta-analyses for sex, occupation, food shortage, household contact, crowding, and lack of clean (i.e., treated) water. The majority of studies were conducted in Brazil, India, or Bangladesh while none were undertaken in low-income countries. Descriptive synthesis indicated that increased age, poor sanitary and socioeconomic conditions, lower level of education, and food-insecurity are risk markers for leprosy. Additionally, in pooled estimates, leprosy was associated with being male (RR = 1.33, 95% CI = 1.06–1.67), performing manual labor (RR = 2.15, 95% CI = 0.97–4.74), suffering from food shortage in the past (RR = 1.39, 95% CI = 1.05–1.85), being a household contact of a leprosy patient (RR = 3.40, 95% CI = 2.24–5.18), and living in a crowded household (≥5 per household) (RR = 1.38, 95% CI = 1.14–1.67). Lack of clean water did not appear to be a risk marker of leprosy (RR = 0.94, 95% CI = 0.65–1.35). Additionally, ecological studies provided evidence that lower inequality, better human development, increased healthcare coverage, and cash transfer programs are linked with lower leprosy risks. These findings point to a consistent relationship between leprosy and unfavorable economic circumstances and, thereby, underscore the pressing need of leprosy control policies to target socially vulnerable groups in high-burden countries.
Background Social protection interventions might improve tuberculosis outcomes and could help to control the epidemic in Brazil. The aim of this study was to evaluate the independent effect of the Bolsa Familia Programme (BFP) on tuberculosis treatment outcomes in Brazil. Methods We prospectively recruited and followed up individuals (aged ≥18 years) who initiated tuberculosis treatment at 42 health-care centres across seven cities in Brazil, between March 1, 2014, and April 30, 2017. Patients were interviewed at health-care centres and information about individual characteristics, socioeconomic status, living conditions, lifestyle, and comorbidities was recorded. Patients were separated into two groups according to BFP beneficiary status: BFP (exposed) or non-BFP (not exposed). Treatment outcome (cure, dropout, death, or development of drug-resistant tuberculosis or treatment failure) was recorded after 6 months of therapy. Pearson's χ² test and ANOVA were used to compare tuberculosis treatment outcomes between the two groups, and we estimated the propensity score of being a beneficiary of the BFP using a logit model. We used multinomial regression models to evaluate the effect of the BFP on tuberculosis treatment outcomes. Findings 1239 individuals were included in the study, of whom 196 (16%) were beneficiaries of the BFP and 1043 (84%) were not. After 6 months of treatment, 912 (87%) of 1043 patients in the non-BFP group and 173 (88%) of 196 patients in the BFP group were cured of tuberculosis, 103 (10%) patients in the non-BFP group and 17 (9%) patients in the BFP group had dropped out, and 25 (3%) patients in the non-BFP group and six (3%) patients in the BFP group had died. Three (<1%) of 1043 patients in the non-BFP group developed drug-resistant tuberculosis. Being a BFP beneficiary had a positive effect for cure (average effect 0•076 [95% CI 0•037 to 0•11]) and a negative effect for dropout (-0•070 [-0•105 to 0•036]) and death (-0•002 [-0•021 to 0•017]). Interpretation BFP alone had a direct effect on tuberculosis treatment outcome and could greatly contribute to the goals of the WHO End TB Strategy.

BackgroundLeprosy is a chronic infectious disease neglected, caused by Mycobacterium leprae, considered a public health problem because may cause permanent physical disabilities and deformities, leading to severe limitations. This review presents an overview of the results of epidemiological studies on leprosy occurrence in childhood in Brazil, aiming to alert health planners and managers to the actual need to institute special control strategies.Methodology/Principal findingsData collection consisted of an electronic search for publications in eight databases: Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scientific Electronic Library Online (SciELO), PuBMed, Biblioteca Virtual em Saúde (BVS), SciVerse Scopus (Scopus), CAPES theses database, CAPES journals database and Web of Science of papers published up to 2016. After apply selection criteria, twenty-two papers of studies conducted in four different regions of Brazil and published between 2001 and 2016 were included in the review. The leprosy detection rate ranged from 10.9 to 78.4 per 100,000 inhabitants. Despite affecting both sexes, leprosy was more common in boys and in 10-14-year-olds. Although the authors reported a high cure proportion (82–90%), between 1.7% and 5.5% of the individuals developed a disability resulting from the disease.Conclusions/SignificanceThe findings of this review shows that leprosy situation in Brazilian children under 15 years is extremely adverse in that the leprosy detection rate remains high in the majority of studies. The proportion of cases involving disability is also high and reflects the difficulties and the poor effectiveness of actions aimed at controlling the disease. The authors suggest the development of studies in spatial clusters of leprosy, where beyond the routine actions established, are included news strategies of active search and campaigns and actions of educations inside the clusters of this disease. The new agenda needs to involve the precepts of ethical, humane and supportive care, in order to achieve a new level of leprosy control in Brazil.

Objective: to analyze association between tuberculosis treatment outcome, sociodemographic characteristics and receipt of social benefits. Methods: this was a cohort study conducted in Salvador, Bahia, Brazil, in the period 2014-2016; we analyzed bivariate associations between treatment outcome, sociodemographic characteristics and social benefits. Results: 216 individuals were followed, of whom 79.6% were cured; higher cure proportion was associated with schooling >9 years (87.5%; p=0.028), marital union (86.3%; p=0.031), and household density ≤2 individuals/bedroom (84.1%; p=0.013); we took as our reference individuals with schooling ≤9 years, not in marital union, and housing density >2 people/bedroom; higher cure proportion was also found among recipients of government and non-government benefits (90.5%), and among those who only received direct benefits (81.6%). Conclusion: schooling >9 years, marital union, and household density ≤2 individuals/bedroom were associated with higher cure; this outcome was more frequent among individuals receiving government and non-government benefits, and among individuals receiving only direct benefits.
BackgroundAlthough leprosy is largely curable with multidrug therapy, incomplete treatment limits therapeutic effectiveness and is an important obstacle to disease control. To inform efforts to improve treatment completion rates, we aimed to identify the geographic and socioeconomic factors associated with leprosy treatment default in Brazil.Methodology/Principal findingsUsing individual participant data collected in the Brazilian national registries for social programs and notifiable diseases and linked as part of the 100 Million Brazilian Cohort, we evaluated the odds of treatment default among 20,063 leprosy cases diagnosed and followed up between 2007 and 2014. We investigated geographic and socioeconomic risk factors using a multivariate hierarchical analysis and carried out additional stratified analyses by leprosy subtype and geographic region. Over the duration of follow-up, 1,011 (5.0%) leprosy cases were observed to default from treatment. Treatment default was markedly increased among leprosy cases residing in the North (OR = 1.57; 95%CI 1.25–1.97) and Northeast (OR = 1.44; 95%CI 1.17–1.78) regions of Brazil. The odds of default were also higher among cases with black ethnicity (OR = 1.29; 95%CI 1.01–1.69), no income (OR = 1.41; 95%CI 1.07–1.86), familial income ≤ 0.25 times Brazilian minimum wage (OR = 1.42; 95%CI 1.13–1.77), informal home lighting/no electricity supply (OR = 1.53; 95%CI 1.28–1.82), and household density of > 1 individual per room (OR = 1.35; 95%CI 1.10–1.66).ConclusionsThe findings of the study indicate that the frequency of leprosy treatment default varies regionally in Brazil and provide new evidence that adverse socioeconomic conditions may represent important barriers to leprosy treatment completion. These findings suggest that interventions to address socioeconomic deprivation, along with continued efforts to improve access to care, have the potential to improve leprosy treatment outcomes and disease control.
RESUMO Objetivo Estimar a frequência de prescrição de medicamentos potencialmente inapropriados (MPIs) para idosos institucionalizados em um hospital psiquiátrico. Métodos Estudo descritivo, transversal, baseado em análise de prescrições médicas para indivíduos com 65 anos ou mais (n = 40), elaboradas no mês de janeiro de 2013 e coletadas de prontuários médicos, em uma instituição hospitalar pública especializada em saúde mental. Foram analisadas variáveis sociodemográficas e clínicas relativas ao idoso. Os medicamentos prescritos foram categorizados, pelos Critérios de Beers (CB), em: 1) MPIs que devem ser evitados em qualquer condição clínica; 2) MPIs nas condições clínicas identificadas no estudo; 3) medicamentos que devem ser utilizados com precaução em idosos. Resultados Houve predomínio do sexo feminino (62,5%, n = 25/40). Em relação à idade, a média foi de 73 anos (66-93 anos). O tempo médio de internamento foi de 15 anos, e o principal diagnóstico foi de esquizofrenia (56,4%; n = 22/39). A prevalência de polifarmácia foi de 70%. Os medicamentos mais prescritos foram prometazina e haloperidol. Em relação aos CB, observou-se que 40,2% (n = 90/224) dos medicamentos prescritos foram classificados como MPIs em qualquer condição clínica; 38,8% (n = 87/224) foram considerados como MPIs em determinadas condições clínicas e 23,7% (n = 53/224) pertenciam à categoria dos medicamentos que devem ser utilizados com cautela em idosos. Conclusão Obteve-se elevada prevalência de MPIs para idosos, quando comparada com estudos semelhantes. Os CBs contribuíram para a análise das prescrições, possibilitando a identificação de medicamentos que podem potencializar os riscos de desenvolvimento de iatrogenias ou agravamento de patologias preexistentes.
