Incidence and prognosis of different types of functional renal failure in cirrhotic patients with ascites.

Background & Aims: Hepatorenal syndrome is a well-characterized type of terminal renal failure that occurs in patients with cirrhosis with ascites. Information about other types of functional renal failure in these patients is scarce. We assessed the incidence and prognosis of different types of functional renal failure in cirrhotic patients with ascites and investigated prognostic factors for these disorders.

A prospective, multicenter, population-based study of BRAF mutational analysis for Lynch syndrome screening.

Background & Aims: Mismatch repair (MMR) deficiencies are the hallmark of tumors arising in Lynch syndrome, however, in approximately 15% of sporadic colorectal cancers (CRC) these deficiencies most often are associated with somatic methylation of the MMR gene MLH1. Recently, an oncogenic mutation in the BRAF gene has been involved in sporadic CRC showing MMR deficiencies as a result of MLH1 promoter methylation. The aim of this study was to evaluate the contribution of BRAF V600E mutation analysis in the identification of MSH2/MLH1 gene mutation carriers in newly diagnosed CRC patients.

Detection of metachronous neoplasms in colorectal cancer patients: identification of risk factors.

Purpose: Patients with colorectal cancer have a high risk of developing metachronous neoplasms. Identification of predictive factors associated with such conditions would allow individualized follow-up strategies in these patients. This study was designed to identify individual and familial factors associated with the development of metachronous colorectal neoplasms in patients with colorectal cancer.

Natural history of patients hospitalized for management of cirrhotic ascites.

Background & Aims: Since the International Ascites Club published the diagnostic criteria of refractory ascites (RA) and hepatorenal syndrome (HRS), there have been few studies assessing the natural history of ascites. The aims of this study were to define the natural history of cirrhotic ascites and to identify prognostic factors for dilutional hyponatremia (DH), RA, HRS, and survival.

Methods: Two hundred sixty-three consecutive cirrhotic patients were followed for 40.

Probability of liver cancer and survival in HCV-related or alcoholic-decompensated cirrhosis. A study of 377 patients.

Background: Although chronic alcohol intake and chronic hepatitis C may progress to cirrhosis and hepatocellular carcinoma (HCC), few data are available about survival and probability of developing HCC in decompensated cirrhosis of both aetiologies.

Methods: This study identified factors related with probability of developing HCC and survival in a cohort of 377 consecutive patients with decompensated HCV-related cirrhosis (200 cases) or alcoholic cirrhosis (177 cases) without known HCC, hospitalized for their first hepatic decompensation, as well as to evaluate differences between both aetiologies. Patients were followed for a mean period of 39 +/- 2 months.
