Abstract
The objective of this work was to review published scientific works on leprosy as a public health problem in Brazil, and the marker of vulnerability for people with the disease. A scoping review was carried out with the descriptor 'leprosy AND vulnerability', on the Virtual Health Library (BVS) database. A total of 29 articles published between January 2016 and December 2020 that met the inclusion criteria were selected. The results pointed to scientific papers published in indexed journals and with different impact factors, with emphasis on the fact that most of the selected publications appear in journals with impact metrics that are not very significant in the eyes of the international community, even though they have national impact. The majority of the studies had municipal coverage, with emphasis on cities in the North and Northeast of Brazil. The works addressed vulnerability in leprosy using different typologies.

Soares GMMDM, Souza EAD, Ferreira AF, García GSM, Oliveira MLWDRD, Pinheiro ABDM, Santos MAMD, Ramos Junior AN. Socio-demographic and clinical factors of leprosy cases associated with the performance of the evaluation of their contacts in Ceará, Brazil, 2008-2019. ACTA ACUST UNITED AC 2021; 30:e2020585. [PMID: 34406220 DOI: 10.1590/s1679-49742021000300024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Accepted: 04/12/2021] [Indexed: 11/21/2022]
Abstract
OBJECTIVE To analyze the effect of sociodemographic and clinical characteristics of new leprosy cases as determinants in the performance of the evaluation of their contacts. METHODS This was a cross-sectional study, with a temporal approach to the evaluation indicator of 100% of contacts examined of each new case (NC) registered in the state of Ceará, Brazil, on the Notifiable Diseases Information System (SINAN), in 2008-2019. Logistic regression was used to estimate odds ratio (OR) with 95% confidence intervals (95%CI). The temporal trends were analyzed using joinpoint regression. RESULTS 23,675 NCs, 65.4% with contacts examined were analyzed. It was less likely to evaluate 100% of the registered contacts when the new cases were multibacillary (OR=1.19 - 95%CI 1.11;1.28) and with examination of contacts as an entry mode (OR=1.71 - 95%CI 1.35;2.18). There was an increasing temporal trend of the indicator (Annual Percentage Change: 2.1 - 95%CI 1.2;3.0). CONCLUSION Distinct dimensions of individual and social vulnerability among new leprosy cases influenced the persistent unsatisfactory performance of the evaluation of contacts.

Social inequalities and their association with the leprosy burden in a Brazilian city of low endemicity: An ecological study. Acta Trop 2021; 218:105884. [PMID: 33676938 DOI: 10.1016/j.actatropica.2021.105884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 02/25/2021] [Accepted: 02/26/2021] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To analyse the association between social inequalities and the leprosy burden in a low endemicity scenario in the state of São Paulo, Brazil. METHODS This ecological study was carried out in the city of Ribeirão Preto, state of São Paulo, Brazil, considering leprosy cases notified from 2006 to 2016. Regarding social inequalities, dimensions related to high household density, literacy, home occupation conditions, health conditions, household income, ethnicity and age were considered. The generalised additive model for location, scale and shape (GAMLSS) was used to verify the association between the social inequalities and leprosy burden. RESULTS The increase in men and women with no education and people with an income of 1 to 2 minimum wages was associated with a relative increase in the number of leprosy cases (7.37%, 7.10% and 2.44%, respectively). Regarding the ethnicity variables, the increase in the proportion of men (black) and women (mixed race) with no schooling was associated with a relative increase in the number of cases of the disease (10.77% and 4.02%, respectively). Finally, for people of mixed race or ethnicity, the increase in the proportion of households with 1/2 to 1 minimum wage was related to a relative decrease in the total number of cases (-4.90%). CONCLUSION The results show that the determinants associated with the increase in leprosy cases are similar to those in Brazilian hyperendemic regions, and that even in cities with low endemicity, social inequality is one of the main determinants of the disease.

Abstract
Reduction in incidence has been associated with the introduction of novel approaches, like chemo/immune-prophylaxis. Incidence determined through follow-up cohort studies can evaluate the implementation of these innovative policies towards control and prevention. We have assessed the incidence in our contacts cohort over past 33 years, considering the effect of demographic and clinical variables. Survival analysis was used to estimate the risk of leprosy. A total of 9024 contacts were evaluated, of which 192 developed leprosy, resulting in an overall incidence of 1.4/1000 person-years. The multivariate analysis showed that the major risk factors were (i) contact from MB index cases and (ii) consanguinity (iii) intra household contact. Lower risk was detected for contacts with BCG scar who were revaccinated. There was a significant decrease in accumulated risk between the 2011-2019 period compared with 1987, probably linked to the improvement in laboratory tools to monitor contacts, thereby providing early diagnosis of contacts at intake and reduction of transmission. Our findings suggest that a combination of contact surveillance and tracing, adequate neurodermatological examination, and availability of molecular tools is highly effective in supporting early diagnosis, while a second dose of the BCG vaccination can exert extra protection.
