Diabetes mellitus and renal involvement in chronic viral liver disease.

HYPOTHESIS: Chronic viral liver disease is often associated with other conditions. Diabetes mellitus (DM) is frequently reported in this context and may play a role in the progression of the liver disease to hepatocellular carcinoma (HCC). Renal disease is also an important extrahepatic manifestation of hepatitis viral infection and its presence is associated with poor prognosis and management issues. OBJECTIVES: Our study had multiple purposes: to determine the frequency of the association between chronic viral liver disease and diabetes mellitus, evaluate the potential of diabetes mellitus as a risk factor for HCC and assess an eventual renal involvement. METHODS AND RESULTS: We included in our study a number of 246 patients with chronic liver disease, from whom 136 were diagnosed with chronic viral hepatitis and 110 with viral liver cirrhosis. These patients were assessed by using a clinical examination and a series of tests, including serum transaminase levels, serum bilirubin, serum albumin, markers of cholestasis, fasting plasma glucose levels, serum creatinine, urea, albuminuria, Addis-Hamburger test, electrophoresis of urinary proteins, abdominal ultrasound and, in some cases, CT examination. We obtained the following results: diabetes mellitus is often associated with chronic liver disease of viral etiology, having been identified in 18.29% of the patients in our study. Age above 60 in patients with chronic hepatitis (p=0.013<0.05) and presence of hepatitis C virus were particularly correlated with the presence of diabetes mellitus. Renal disease was present in 13.4% of the patients with chronic liver disease and it was especially associated with liver cirrhosis and hepatitis C virus. The most common form of renal injury was glomerulonephritis. Acute kidney injury was diagnosed only in cirrhotic patients as hepatorenal syndrome, occurring in 7.27% of the subjects, while chronic kidney disease was identified only in two cases of chronic viral hepatitis. Four patients in our study were diagnosed with HCC and none of them presented diabetes mellitus. DISCUSSION: Our study revealed that there is a significant association between diabetes mellitus and chronic viral liver disease induced by hepatitis C virus. Glomerulonephritis was the most common type of renal disease in both hepatitis patients and in those with cirrhosis. Glomerular injury was strongly correlated with the presence of hepatitis C virus than with hepatitis B virus. A connection between diabetes mellitus and hepatocellular carcinoma could not be established.

Wireless Capsule Endoscopy in Correlation with Software Application in Gastrointestinal Diseases.

Wireless capsule endoscopy is one of the most recent investigation techniques of gastrointestinal pathology. Unlike conventional upper and lower endoscopy, it has the advantages of being a noninvasive and painless procedure. One of the capsule endoscopy disadvantages is represented by the necessary time to analyze the video frames obtained. Software applications proposed in this purpose could offer support in the images evaluation. Different algorithms have been described in the literature, but further research is needed to establish the practical value of computer vision tools in gastroenterology.

Particularities of Renal Manifestations in Chronic Viral Hepatitis.

INTRODUCTION: Chronic viral hepatitis represent major health problems worldwide, with an evolution that is sometimes marked by a series of extrahepatic manifestations. Among these, kidney disease may occur, either as glomerulonephritis, and/or renal dysfunction. MATERIAL AND METHODS: The purpose of this study was to achieve a complete assessment of the liver and kidney function in a series of patients diagnosed with chronic viral hepatitis, in order to identify a possible kidney disease in this context. 104 patients with chronic viral hepatitis B and C, aged between 25 and 80, were included in the study. These patients were assessed by a series of tests that allowed us to perform a complete evaluation of both liver and kidney function: liver cytolysis enzymes, serum bilirubin, markers of cholestasis, markers of viral infection, urinalysis, albuminuria, electrophoresis of urinary proteins, urea, creatinine, and abdominal ultrasound. RESULTS: Glomerular injury was a rare finding in patients with chronic hepatitis. Patients with chronic hepatitis B had glomerular disease in 5,88 % of cases, while 10 % of the patients with hepatitis C presented this type of renal disease. Acute kidney injury was not identified in our patient group. None of the patients in the hepatitis B study group presented chronic kidney disease. CKD was present in two patients with chronic hepatitis C that had no other associated conditions.
