ABSTRACT
Objective: chronic kidney disease (CKD) is an increasing common problem in the world due to the exponential growth of diabetes mellitus, hypertension and other risk factors. The aim of this study is to investigate urinary abnormalities and risk factors for kidney disease in the general population. Methods: this study was performed from data collected during the annual World Kidney Day (WKD) campaigns, in Fortaleza, Ceará, Brazil, between 2009 and 2012. The population sought assistance spontaneously in stands placed in high people-traffic areas. Results: among 2,637 individuals interviewed, the mean age was 50.7±15.7 years and 53% were male. The main risk factors found were sedentarism (60.7%), obesity (22.7%) and smoking (19.8%). Blood pressure (BP) > 140x90 mmHg was found in 877 (33%). Increased BP was found for the first time in 527 cases (19.9%). Cardiovascular diseases were reported in 228 (8.6%). Diabetes was related by 343 (13%). Capillary blood glucose > 200 mg/dL was found in 127 (4.8%) and it was > 200 mg/dL for the first time in 30 (1.13%). Urinalysis was performed in 1,151 people and found proteinuria in 269 (23.3%). Proteinuria was most frequent in hypertension people (77.3% vs. 55.8%, p=0.0001), diabetes mellitus (22.7% vs. 15.2%, p=0.005) and elderly (42.1% vs. 30.7%, p=0.0007). Conclusion: risk factors for CKD are frequent in the general population. Many individuals had hypertension and diabetes and did not know this. It is important to regularly perform actions like WKD in order to early detect potential candidates for CKD. .
Objetivo: a doença renal crônica (DRC) é um problema crescente no mundo em razão do crescimento exponencial do diabetes mellitus, da hipertensão e de outros fatores de risco. O objetivo deste estudo é investigar alterações urinárias e fatores de risco para doença renal na população geral. Métodos: este estudo foi realizado a partir de dados coletados durante as campanhas anuais do Dia Mundial do Rim, em Fortaleza, Ceará, Brasil, entre 2009 e 2012. A população buscou atendimento espontaneamente nos stands montados em locais de alto tráfego de pessoas. Resultados: entre 2.637 indivíduos entrevistados, a média de idade foi de 50,7±15,7 anos, sendo 53% do gênero masculino. Os principais fatores de risco encontrados foram sedentarismo (60,7%), obesidade (22,7%) e tabagismo (19,8%). Pressão arterial (PA) > 140x90 mmHg foi encontrada em 877 casos (33%). Aumento da PA foi encontrado pela primeira vez em 527 casos (19,9%). Doenças cardiovasculares foram relatadas por 228 indivíduos (8,6%). Diabetes foi relatado por 343 indivíduos (13%). Glicemia capilar > 200 mg/dL foi encontrada em 127 casos (4,8%) e > 200 mg/dL pela primeira vez em 30 (1,13%). O exame de urina foi realizado por 1.151 pessoas, sendo encontrada proteinúria em 269 casos (23,3%). Proteinúria foi mais frequente em pessoas com hipertensão (77,3% vs. 55,8%, p = 0,0001), diabetes mellitus (22,7% vs. 15,2%, p = 0,005) e em idosos (42,1% vs. 30,7%, p = 0,0007). Conclusão: fatores de risco para DRC são frequentes na população geral. Muitos indivíduos tinham hipertensão e diabetes e não sabiam disso. É importante a realização de ações como o Dia Mundial do Rim com o objetivo de detectar precocemente potenciais candidatos à DRC. .
ABSTRACT
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.

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.

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 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. .

BACKGROUND: The aim of this study was to compare clinical manifestations, laboratory data, morbidity and mortality between adults and children with visceral leishmaniasis, with a focus on kidney function. METHODS: This was a retrospective cohort study with 432 patients with visceral leishmaniasis diagnosed at 1 center in the northeast of Brazil. Patients were divided into 2 groups according to age (>21 years and ≤ 21 years old). RESULTS: The time between onset of symptoms and beginning of treatment was longer in adults (89.5 versus 48.5 days, P < 0.001); signs and symptoms were similar in both groups. Failure of treatment with glucantime was more common in adults (17.6% versus 8.8%, P = 0.008). Acute kidney injury was observed in 160 patients (37.0%), and it was more severe in adults. Risk factors for acute kidney injury in adults were hypokalemia, leukopenia, chills and amphotericin B use. In children, secondary infections were found to increase the risk for acute kidney injury. Overall mortality was 8.8%, and it was significantly higher in adults (12.6% versus 4.1%, P = 0.002). CONCLUSIONS: The adult population had more severe laboratory abnormalities and a worse prognosis, possibly due to delay in diagnosis. Acute kidney injury is prevalent in both groups, and it is usually more severe in adults.
