RESUMO

AIM: Acute kidney injury (AKI) is one of the main causes of morbidity and mortality in cases of envenomation by venomous snakes. The present study was carried out to investigate the clinical and laboratory manifestations in accidents with venomous snakes and the risk factors associated with AKI in these accidents. METHODS: A retrospective study was carried out with patients victims of snakebite admitted to a reference centre. AKI was defined according to the RIFLE and AKIN criteria. RESULTS: A total of 276 patients were included, of which 230 (83.7%) were males. AKI was observed in 42 cases (15.2%). The mean genus involved in the accidents was Bothrops (82.2%). Mean age of patients with AKI was higher than in patients without AKI (43 ± 20 vs. 34 ± 21 years, P = 0.015). The time elapsed between the accident and medical care was higher in the AKI group (25 ± 28 vs. 14 ± 16h, P = 0.034), as well as the time elapsed between the accident and the administration of antivenom (30.7 ± 27 vs. 15 ± 16 h, P = 0.01). Haemodialysis was required in 30% of cases and complete renal function recovery was observed in 54.8% of cases at hospital discharge. There were four deaths, none of which had AKI. Factors associated with AKI were haemorrhagic abnormalities (P = 0.036, OR = 6.718, 95% CI: 1.067-25.661) and longer length of hospital stay (P = 0.004, OR = 1.69, 95% CI 1.165-2.088). CONCLUSION: Acute kidney injury is an important complication of snakebite accidents, showing low mortality, but high morbidity, which can lead to partial renal function recovery.

RESUMO

Ophidic accidents are an important public health problem due to their incidence, morbidity and mortality. An increasing number of cases have been registered in Brazil in the last few years. Several studies point to the importance of knowing the clinical complications and adequate approach in these accidents. However, knowledge about the risk factors is not enough and there are an increasing number of deaths due to these accidents in Brazil. In this context, acute kidney injury (AKI) appears as one of the main causes of death and consequences for these victims, which are mainly young males working in rural areas. Snakes of the Bothrops and Crotalus genera are the main responsible for renal involvement in ophidic accidents in South America. The present study is a literature review of AKI caused by Bothrops and Crotalus snake venom regarding diverse characteristics, emphasizing the most appropriate therapeutic approach for these cases. Recent studies have been carried out searching for complementary therapies for the treatment of ophidic accidents, including the use of lipoic acid, simvastatin and allopurinol. Some plants, such as Apocynaceae, Lamiaceae and Rubiaceae seem to have a beneficial role in the treatment of this type of envenomation. Future studies will certainly find new therapeutic measures for ophidic accidents.

RESUMO

The aim of this study was to describe the epidemiological profile of snakebite accidents reported by the toxicological assistance center in Fortaleza, Ceará, Brazil. Database information on snakebite accidents was analyzed regarding the period from January 2003 to December 2011. A total of 1063 cases were found. The accidents occurred during the rainy months (March, April and May), in urban areas (52.3%), affecting individuals younger than 50 years and predominantly among males (70.7%). The lower limbs were the most frequently affected body area (33.7%). Most accidents involved non-venomous snakes (76.1%). The genus Bothrops was the main one involved in venomous accidents (83%). It is expected that this study can be used as the substrate to improve healthcare surveillance and implementing better measures for the treatment of this population.

RESUMO Os acidentes ofídicos são importante problema de saúde pública devido à incidência, morbidade e mortalidade. Aumento do número de casos tem sido registrado no Brasil nos últimos anos. Vários estudos apontam para a importância do conhecimento das complicações clínicas e do tratamento adequado desses acidentes. Entretanto o conhecimento dos fatores de risco não é suficiente, e existe número crescente de óbitos devido a esses acidentes no Brasil. Neste contexto, a injúria renal aguda (IRA) aparece como uma das principais causas de óbito e sequela nestas vítimas, que são principalmente homens trabalhadores de zonas rurais. Os gêneros Bothrops e Crotalus são os principais responsáveis pelo envolvimento renal nos acidentes ofídicos na América do Sul. O presente estudo faz uma revisão da literatura sobre a IRA causada pela picada das serpentes dos gêneros Bothrops e Crotalus em suas diversas características, enfatizando a abordagem terapêutica mais adequada para estes casos. Estudos recentes tem sido realizados para a busca de terapias complementares para o tratamento dos acidentes ofídicos, incluindo o uso de ácido lipóico, sinvastatina e alopurinol. Algumas plantas, como a Apocynaceae, Lamiaceae e Rubiaceae parecem ter papel benéfico no tratamento destes envenenamentos. Estudos futuros irão certamente encontrar novas estratégias terapêuticas para os acidentes ofídicos. .

RESUMO O objetivo deste estudo é descrever o perfil epidemiológico dos acidentes ofídicos atendidos e notificados ao Centro de Assistência Toxicológica (CEATOX), em Fortaleza, Ceará, Brasil. Foram analisadas informações sobre os acidentes ofídicos relativos ao período compreendido entre janeiro de 2003 a dezembro de 2011, por meio de banco de dados. Os resultados demonstraram 1063 casos notificados ao CEATOX, Ceará. Os acidentes ocorreram principalmente em meses chuvosos (março, abril e maio), em áreas urbanas (52,3%), em uma faixa etária menor de 50 anos, acometendo predominantemente o sexo masculino (70,7%). Os membros inferiores foram os locais mais afetados (33,7%). A maior parte dos acidentes envolveu serpentes não peçonhentas (76,1%). O gênero Bothrops foi o maior responsável pelos acidentes com serpentes peçonhentas (83%). Espera-se que os dados da casuística obtida sirvam de ferramenta para o planejamento de medidas de saúde voltadas para prevenção e atendimento mais adequado da população em estudo. .
