Although leprosy is recognised as a disease of poverty, there little evidence on the specific socioeconomic factors associated with risk. To inform targeted strategies for elimination, we investigated markers risk in Brazil.

Background The elimination strategy reduced known leprosy prevalence but the detection rate remains high in many countries, including Brazil. Brazilian imposes a limit to reduction of short term. knowledge time behaviour and spatial distribution statistics will contribute decision making for control. Method numbers newly diagnosed cases by region year from 1980 2004, prevalent 1990 2007 were fitted as parabolic function negative binomial regression models. To detect areas with increased...

Treatment default is a serious problem in tuberculosis control because it implies persistence of infection source, increased mortality, relapse rates and facilitates the development resistant strains.This study analyzed treatment determinants Amazonas State to contribute planning appropriate interventions.Observational with retrospective cohort using Brazilian Disease Notification System data from 2005 2010. A nested case design was used. Patients defaulting were considered as 'cases' those...

To evaluate the impact of Brazilian cash transfer programme (Bolsa Família Programme, BFP) on tuberculosis (TB) incidence in Brazil from 2004 to 2012.We studied surveillance data using a combination an ecological multiple-group and time-trend design covering 2458 municipalities. The main independent variable was BFP coverage outcome TB rate. All study variables were obtained national databases. We used fixed-effects negative binomial models for panel adjusted selected covariates representing...

Background Leprosy control is based on early diagnosis and multidrug therapy. For treatment purposes, leprosy patients can be classified as paucibacillary (PB) or multibacillary (MB), according to the number of skin lesions. Studies regarding a uniform regimen (U-MDT) for all have been encouraged by WHO, rendering disease classification unnecessary. Methodology findings An independent, randomized, controlled clinical trial conducted from 2007 2015 in Brazil, compared main outcomes (frequency...

Since leprosy is both treated and controlled by multidrug therapy (MDT) it important to monitor recurrent cases for drug resistance distinguish between relapse reinfection as a means of assessing therapeutic efficacy.

Abstract Background Leprosy continues to be an important cause of physical disability in endemic countries such as Brazil.

Host genetic susceptibility to leprosy has been intensively investigated over the last decades; however, there are no studies on role of variants in disease recurrence. A previous initiative identified three recurrent cases for which none M. leprae strains, as obtained first and second diagnosis, had any known genomic associated resistance Multidrug therapy; addition, whole genome sequencing indicated that same was causing two out recurrences. Thus, these individuals were suspected being...
