RESUMO
Abstract We aimed to determine the effects of boric acid and quercetin on contrast media-induced nephropathy in rats. Thirty-two rats were divided into four equal groups with eight rats in each group: the control (C) group, contrast media (CM) group, contrast media plus boric acid (CMB) group, and contrast media plus quercetin (CMQ) group. Boric acid (H3(BO)3, 4% solution) at a dose of 200 mg/kg was administered by oral gavage to rats in the group CMB once daily for 4 consecutive days (days 1 to 4). Quercetin at a dose of 50 mg/kg was administered by oral gavage to rats in the CMQ group once daily for 4 consecutive days (days 1 to 4). A significant decrease was found in the serum urea and creatinine levels in the CMQ group compared with the CM group (P <0.01). The serum nitrite and nitrate levels were higher in the CM group than in the C group and were lower in the CMQ group than in the CM group (P <0.01). A significant decrease in the severity of tubular necrosis was found in the CMQ group compared to the CM group (P <0.05). Quercetin had protective effects against contrast nephropathy, but no beneficial effect of boric acid was found.
RESUMO
El objetivo de este estudio fue evaluar a los pacientes con fiebre mediterránea familiar (familial Mediterranean fever, FMF) y dolor abdominal crónico resistentes al tratamiento con colchicina. Se incluyó a 48 pacientes diagnosticados en nuestro consultorio de reumatología pediátrica que tenían dolor abdominal a pesar del tratamiento con colchicina. A todos los pacientes se los derivó a un gastroenterólogo pediátrico. Se registraron las características del dolor, tales como aparición, duración y frecuencia; se planificó una endoscopía digestiva para obtener un diagnóstico diferencial. Se determinó la presencia de una mutación del gen MEFV en 46 pacientes. La mediana de la duración del tratamiento fue de 2,8 años. Aproximadamente el 60% de los pacientes tenían dolor abdominal todos los días o de dos a tres veces a la semana; en el 73% de los casos, duró menos de tres horas. A 41 pacientes se les realizó una endoscopía digestiva alta. La gastroduodenitis es un hallazgo frecuente en los pacientes con FMF y dolor abdominal persistente a pesar del tratamiento. Los pacientes con los puntajes más altos de severidad de la enfermedad tenían inflamación digestiva grave.
The aim of the study to evaluate familial mediterranean fever (FMF) patients with chronic abdominal pain unresponsive to colchicine treatment. Forty-eight patients who diagnosed in our Pediatric Rheumatology clinics and suffering from abdominal pain despite colchicine treatment were include. All patients were referred to a pediatric gastroenterologist. The pain characteristics such as onset, duration and frequency were recorded; gastrointestinal (GI) endoscopy was planned for differential diagnosis. MEFV mutation was determined in 46 patients. The median duration of treatment was 2.8 years. Approximately 60% of the patients suffered from abdominal pain every day or 2-3 times a week, in 73% of the cases it lasted less than three hours. Forty-one patients underwent upper GI endoscopy. Gastroduodenitis is a common finding in persisting abdominal pain despite therapy of FMF patients. The patients with the highest disease severity scores had severe inflammation within the entire GI system.
