Hepatorenal failure, a well-recognized complication of established liver disease, is characterized by early renal hemodynamic changes (vasoconstriction) before clinically recognized kidney disease. This renal vasoconstriction (increased renal vascular resistance) should be detectable noninvasively by Doppler ultrasonography. We studied whether renal Doppler ultrasonography detects abnormalities...

To determine the overall gain of the hepatorenal reflex, hypertonic NaCl solutions were infused into the portal vein or inferior vena cava of anesthetized dogs at a rate of 0.01 ml/kg/min for 30 min and the urinary Na excretion measured. Infusion of 2.25% NaCl into either the portal vein or inferior vena cava had no effect. Portal infusion of 4.5% or 9% NaCl produced an increase of 36 +/- 16 or...

The preventative effect of caffeic acid phenyl ester (CAPE) against hematological, blood coagulation, and hepatorenal disturbances in cadmium (Cd) intoxication was investigated in rats. Male Wistar rats were randomly assigned into control group, Cd-group, and Cd + CAPE group. Cd intoxication was induced by intraperitoneal injection (i.p.) of CdCl2 (1 mg/kg/day) for 21 days, and CAPE was daily g...

To investigate mechanisms by which thymoquinone (TQ) can prevent methotrexate- (MTX-) induced hepatorenal toxicity, TQ (10 mg/kg) was administered orally for 10 days. In independent rat groups, MTX hepatorenal toxicity was induced via 20 mg/kg i.p. at the end of day 3 of experiment, with or without TQ. MTX caused deterioration in kidney and liver function, namely, blood urea nitrogen, creatinin...

Patient selection and survival after peritoneovenous shunting for nonmalignant ascites was assessed in 30 patients undergoing 44 peritoneovenous shunting procedures over a 5-year period. Indications for peritoneovenous shunting included refractory ascites alone, refractory ascites complicated by hepatorenal syndrome, and nonrefractory but recurrent ascites. Fifty-six percent of shunting procedu...

Renal failure is common in cirrhosis, especially in patients with ascites. It is typically secondary to one or more intercurrent events, which further compromise renal perfusion on a background of a relative reduction in renal perfusion and may have a negative impact on survival. An accurate and prompt diagnosis and treatment of renal complications in cirrhosis is therefore essential to improve...

Background. Alcoholic liver disease is a major cause of liver cirrhosis and the hepatorenal syndrome is a serious complication. Risk factors for hepatorenal syndrome (HRS) in alcoholic liver cirrhosis are not entirely explored. Aim. To assess the risk factors for hepatorenal syndrome in alcoholic liver cirrhosis. Patients and Methods. Consecutive patients with alcoholic liver disease were follo...

The vasoconstrictor terlipressin is used for type 1 hepatorenal syndrome (HRS-1) in many parts of the world and part clinical practice guidelines Europe.

OBJECTIVE To compare the accuracy of computer-aided ultrasound (US) and magnetic resonance imaging (MRI) by means of hepatorenal gradient analysis in the evaluation of nonalcoholic fatty liver disease (NAFLD) in adolescents. MATERIALS AND METHODS This prospective, cross-sectional study evaluated 50 adolescents (aged 11-17 years), including 24 obese and 26 eutrophic individuals. All adolescent...

objective(s): this study aimed to develop drugs from natural sources to overcome the side effects of many of synthetic drugs. methanol extracts of both pericarp and seeds of pleiogynium solandri were used to investigate antioxidant, hepatoprotective, and renal function protective, analgesic, and anti-inflammatory effects and to determine the chemical composition of the extract responsible for b...
