Introduction. Renal disease plays an important role in the prognosis and evolution of chronic liver disease, in particular in its advanced stages. The aim of our study is to analyze the prevalence of chronic liver disease (hepatitis and cirrhosis of different etiologies) and to assess possible correlations between these and impaired renal function.  Material and methods. We conducted a retrospective observational study based on data collected from observation charts of patients admitted to the 2nd Medical Clinic, Emergency County Hospital Tirgu-Mures between January 1st 2012-December 31 2013. In this study we included, based on informed consent, 401 patients with documented liver pathology, with preserved or modified renal function.  Results. Age distribution shows that 41.1% of cases occured between 51 and 60 years of age. Sex distribution shows that 65.3% of cases were male. Toxic cirrhosis was found in 40.8% of males and viral C cirrhosis in 15.1% of women. Toxic cirrhosis associated the following complications: ascites (35.7%), encephalopathy (75%), PAH (68.6%), esophageal varices and upper GI bleed (35.7%). Analyzing the risk factors of renal failure we found that increased mean values of creatinine are associated with viral B cirrhosis (p = 0.02), portal vein diameter (OR 1.37), portal hypertension (OR 1.24), male gender (OR 1.84) and the age group 61-70 yo (OR 1.04).  Conclusions. The current study demonstrated that renal function in chronic liver disease correlates with viral etiology of liver disease, its advanced stage, presence of portal hypertension, older age and male gender.
