“…Since 1987, dozens of cases of HVL/HIV have been described in Brazil and other parts of the world (Ministério da Saúde, 2014; World Health Organization., 2015). Coinfection has modified the epidemiological profile due to the expansion of leishmaniasis from rural to urban areas, places with higher HIV prevalence and expanded among developing countries (Carvalho et al , 2014; Ministério da Saúde., 2015; Druzian et al , 2015), as well as developed countries (Herrador et al , 2015). According to the search criteria used, only two studies in Europe were found included among the inclusion criteria, different from the cases described in the scientific literature with the prevalence and effective distribution of LV/HIV coinfection, much more frequent in African countries than in Europe (de Albuquerque et al , 2014; Martins-Melo et al , 2014).…”

Epidemiological, clinical and laboratory aspects of human visceral leishmaniasis (HVL) associated with human immunodeficiency virus (HIV) coinfection: a systematic review

Coinfection with human visceral leishmaniasis (HVL) and human immunodeficiency virus (HIV) has become an emerging public health problem in several parts of the world, with high morbidity and mortality rates. A systematic review was carried out in the literature available in PubMed, Scielo and Lilacs related to HVL associated with HIV coinfection, seeking to analyze epidemiological, clinical and laboratory aspects. Of the 265 articles found, 15 articles were included in the qualitative analysis, which referred to the results of HVL treatment in patients coinfected with HIV. In the published articles between 2007 and 2015, 1171 cases of HVL/HIV coinfection were identified, 86% males, average age 34 years, liposomal amphotericin B was the most commonly used drug, cure rates 68 and 20% relapses and 19% deaths, five different countries, bone marrow was used in 10/15 manuscripts. HVL/HIV coinfection is a major challenge for public health, mainly due to the difficulty in establishing an accurate diagnosis, low response to treatment with high relapse rates and evolution to death. In addition, these two pathogens act concomitantly for the depletion of the immune system, contributing to worsening the clinical picture of these diseases, which requires effective surveillance and epidemiological control measures.

“…The generation of LISA map showed clusters of HVL and CVL cases, suggesting places with higher and lower need of interventions, in which 0 indicated non-significant ( P > 0.05) that showed inexistence of self-correlation; 1 had low self-correlation, with a 95% confidence level ( P = 0.05); 2, medium self-correlation and 99% confidence ( P = 0.01); and 3 indicated existence of high self-correlation and 99.9% ( P = 0.001) (Barbosa et al ., 2014; Carvalho and Nascimento, 2014; Fontoura et al ., 2016).…”

Human visceral leishmaniasis (HVL) cases are important public health problems due to their zoonotic aspect, with high rates of morbidity and mortality in Brazil. The aim of this this study was to identify spatial patterns in both rates of HVL cases in Brazilian states during the period from 2006 to 2015. This is an ecological study, using geoprocessing tools to create choropleth maps, based on secondary data from open access platforms, to identify priority areas for control actions of the disease. Data were collected in 2017 and analysed according to the global and local Moran's I, using TerraView 4.2.2 software. Similar clusters were observed in neighbouring municipalities in thematic maps of HVL, suggesting spatial similarity in the distribution of the disease in humans mainly in the North and Northeast Regions, which concentrate the states with the highest rates of HVL. Heterogeneous spatial patterns were observed in the distribution of HVL, which show municipalities that need higher priority in the intensification of disease surveillance and control strategies.

“…The use of spatial analysis and Geographic Information System (GIS) tools allows the creation of maps that help in the analysis and better understanding of spatial patterns of epidemiological data distribution, making it possible to detect areas of greater risk, as well as associated factors to indicate points with greater and smaller need for intensification and/or prioritization of control measures [ 20 , 22 – 25 ]. Although geographic distribution models have been widely applied to analyze the spatial distribution of other diseases such as visceral leishmaniasis [ 20 , 23 , 25 , 26 ], dengue [ 22 ], leprosy [ 27 ], neonatal mortality [ 24 ] and malaria [ 28 ], they have been little used in the context of diarrheal diseases [ 1 ].…”

BackgroundDiarrhea is a waterborne disease that affects children, especially those under 5 years of age. The objective of this study was to identify the spatial patterns of distribution of diarrheal disease in under 5-year-old children in the State of Tocantins, Brazil, from 2008 to 2013.MethodsGeoprocessing tools were used to carry out an epidemiological study, to prepare thematic maps in the TerraView 4.2.2 software based on secondary data. General indicators of the disease, presence of spatial dependence through the Global Moran’s Index (I) and the Spatial Association Index (LISA) were described.ResultsThere were 3,015 cases of under 5-year-old children hospitalized for diarrhea, with an average annual rate (AAR) of 4.10/1,000 inhabitants (inhab.). Among the main characteristics were: increasing rates in under 1-year-old children (6.16 to 9.66/1,000 inhabitants); children aged 1 to 4 full years (63%); males (55%); 8 deaths of under one-year-old children (75%); county of Araguaína (67%); incidence in the county of Nazaré (63.97/1,000 inhab.); prevalence and incidence in the Araguaína microregion (45%, AAR 9.38/1,000 inhab.). The presence of a cluster with spatial autocorrelation was found in the Araguaína microregion, which was statistically significant (I = 0.11, p-value < 0.03), with priority of intervention (Moran Map).ConclusionsThere was an increase in the number of hospitalizations for diarrhea in under 5–year-old children in the state of Tocantins. The spatial analysis identified clusters of priority areas for measures of maintenance and control of diarrheal diseases.
