OCTREOTIDE BLUNTS POSTPRANDIAL SPLANCHNIC HYPEREMIA IN CIRRHOTIC-PATIENTS - A DOUBLE-BLIND RANDOMIZED ECHO-DOPPLER STUDY

The effect of octreotide, a long-acting synthetic analog of somatostatin, on fasting and postprandial splanchnic hemodynamics was investigated in cirrhotic patients, Splanchnic hemodynamics were assessed using an echo-Doppler duplex system in a prospective, double-blind, placebo-controlled, crossover study performed on 2 separate days, 1 week apart, in 30 cirrhotic patients. Measurements of portal vein (PV) cross-sectional area (PV-A) and mean velocity (PV-V), and of superior mesenteric artery (SMA) mean velocity (SMA-V) and pulsatility index (SMA-PI) (an index of vascular resistance) were performed at baseline, 30 minutes after octreotide (200 mu g subcutaneously) or placebo administration, and 30 and 60 minutes after the ingestion of a liquid meal. In the fasted state, octreotide induced a significant decrease in PV-V (-7%) and in SMA-V (-10%) and an increase in PI (+16%). On the day of placebo administration, meal ingestion induced a significant increase in PV-V (+21%) and in SMA-V (+43%) and a decrease in PI (-21%). In contrast, meal ingestion on octreotide day induced significantly smaller increases in PV-V (+10%) and in SMA-V (+18%) and a significantly smaller decrease in PI (-10%). Octreotide, although producing a mild reduction in PV-V and SMA-V in the fasted state, markedly blunts postprandial splanchnic hyperemia in cirrhotic patients

The management of ascites in cirrhosis: report on the consensus conference of the International Ascites Club

Ascites is a common complication of cirrhosis, and heralds a new phase of hepatic decompensation in the progression of the cirrhotic process. The development of ascites carries a significant worsening of the prognosis. It is important to diagnose noncirrhotic causes of ascites such as malignancy, tuberculosis, and pancreatic ascites since these occur with increased frequency in patients with liver disease. The International Ascites Club, representing the spectrum of clinical practice from North America to Europe, have developed guidelines by consensus in the management of cirrhotic ascites from the early ascitic stage to the stage of refractory ascites. Mild to moderate ascites should be managed by modest salt restriction and diuretic therapy with spironolactone or an equivalent in the first instance. Diuretics should be added in a stepwise fashion while maintaining sodium restriction. Gross ascites should be treated with therapeutic paracentesis followed by colloid volume expansion, and diuretic therapy. Refractory ascites is managed by repeated large volume paracentesis or insertion of a transjugular intrahepatic portosystemic stent shunt (TIPS). Successful placement of TIPS results in improved renal function, sodium excretion, and general well-being of the patient but without proven survival benefits. Clinicians caring for these patients should be aware of the potential complications of each treatment modality and be prepared to discontinue diuretics or not proceed with TIPS placement should complications or contraindications develop. Liver transplantation should be considered for all ascitic patients, and this should preferably be performed prior to the development of renal dysfunction to prevent further compromise of their prognosis
