SUMMARY INTRODUCTION: Chronic kidney disease has presented frequencies that exceed the installed capacity of dialysis services, and data on prevalence are uncertain worldwide. OBJECTIVE: The objective of this study was to analyze the epidemiological profile of patients assisted in renal replacement therapy and details on the assistance provided. METHODS: Population-based cross-sectional study with information obtained from the Unified Health System database. The research location was the state of Paraíba, and the observation period was from January 1, 2009, to December 31, 2013, n = 64,676 documents, and the variables observed were: gender; age group, race, or color; place of residence; place where the therapy was performed; vascular access; modality if hemodialysisor peritoneal dialysis; registration on the kidney transplantation list; infection by hepatitis B, C, and HIV viruses; and costs. RESULTS: A higher prevalence of request for highly complex procedure was observed in males (56.8%) and white (39%). The cities with the highest prevalence of dialysis patients were João Pessoa, Campina Grande, Santa Rita, Sousa, Bayeux, and Patos. Most of the sample referred to patients undergoing hemodialysis as a renal replacement therapy modality, with 42.2% not having definitive arteriovenous fistula access. The renal replacement therapy expenses observed were increasing, and in 2009, they accounted for 2.89% of health spending, reaching 3.32% of state health spending in 2013. CONCLUSION: Using secondary data from DATASUS to understand the population with chronic kidney disease and the assistance offered is possible.

Resumo O Brasil é o principal consumidor de agrotóxicos do mundo. O uso em larga escala destes produtos é capaz de contaminar os principais compartimentos ambientais e expor um maior número de pessoas a seus efeitos tóxicos. Portanto, realizou-se esta revisão de literatura com o objetivo de buscar subsídios para uma discussão qualificada sobre a atuação da Vigilância em Saúde Ambiental (VSA) no âmbito do Sistema Único de Saúde relacionada com a contaminação atmosférica por agrotóxicos e riscos à saúde. Doze artigos foram selecionados e analisados nesta revisão de literatura. Destes, apenas um foi publicado em periódico especializado na área da saúde pública. Apesar disso, dois estudos epidemiológicos publicados na área das ciências ambientais investigaram a associação entre o ar contaminado por agrotóxicos e desfechos específicos como, linfoma não Hodgkin (LNH) e esclerose lateral amiotrófica (ELA). Nossos achados refletem a carência de estudos abordando o tema pela saúde pública. A discussão sobre a contaminação atmosférica por agrotóxicos e riscos potenciais à saúde humana deve ser ampliada pela ciência brasileira, a fim de aprofundar o conhecimento sobre o assunto e respaldar a capacidade de atuação da VSA.

Abstract Brazil is the main consumer of pesticides in the world. Large-scale use of these products is likely to contaminate major environmental compartments and expose more people to their toxic effects. Therefore, this literature review was carried out to seek supporting elements for a qualified discussion about the performance of Environmental Surveillance (HS) within the Brazilian Unified Health System (SUS) related to air contamination by pesticides and health risks. Twelve papers were selected and analyzed in this literature review. Of these, only one was published in a specialized public health journal. Notwithstanding this, two epidemiological studies published in the field of environmental sciences investigated the association between air contaminated by pesticides and specific outcomes such as non-Hodgkin’s lymphoma (NHL) and amyotrophic lateral sclerosis (ALS). Our findings reflect the lack of studies addressing such issue by public health. The discussion on air contamination by pesticides and potential risks to human health should be expanded by Brazilian science in order to further increase knowledge on the subject and support the HS performance capacity.
