Ultrasound detection of abdominal lymph nodes in chronic liver diseases. A retrospective analysis
Aim: To retrospectively evaluate the prevalence of lymph nodes of the hepato-duodenal ligament in a group of patients with chronic liver disease of various aetiologies and to investigate what clinical, aetiological and laboratory data may lead to their appearance. Materials and methods: One thousand and three patients (554 men, 449 women) were studied, including 557 with chronic hepatitis and 446 with liver cirrhosis. The presence of lymph nodes near the trunk of the portal vein, hepatic artery, celiac axis, superior mesenteric vein and pancreas head was investigated using ultrasound. Results: Lymph nodes were detected in 394 out of the 1003 study patients (39.3%); their number ranged from …
Hemodynamic changes in splanchnic circulation after orthotopic liver transplantation in patients with liver cirrhosis
Background: Liver cirrhosis increases portal vein pressure and alters the splanchnic circulation. With Doppler sonography, we investigated the hemodynamic changes in the portal vein, superior mesenteric artery, hepatic and splenic arteries and spleen size in a group of patients with end-stage liver disease before and after orthotopic liver transplantation (OLT). Methods: Ten patients (seven male, three female; mean age = 48.8 ± 7.6 years) who underwent OLT for liver cirrhosis mainly associated with hepatitis C virus infection completed the study. The control group consisted of 10 patients matched by sex and age who had no gastroenterologic or vascular diseases. All patients underwent duplex…
Ultrasound detection of abdominal lymphadenomegaly in subjects with hepatitis C virus infection and persistently normal transaminases: a predictive index of liver histology severity.
The indications for liver biopsy in anti-HCV-positive patients with persistently normal alanine aminotransferase levels are not clearly established. Recent studies have correlated the presence of abdominal lymphoadenomegaly with disease severity in patients with chronic hepatitis C. Our study aimed to evaluate the frequency of abdominal lymphoadenomegaly in an anti-HCV positive blood donor population with persistently normal alanine aminotransferase and the relationship of abdominal lymphoadenomegaly with the severity of liver changes.Eighty-six anti-HCV positive blood donors (58 M, 28 F) with normal alanine aminotransferase were followed up for a median of 31 months (range 12-50). To evalu…
Screening for Autoantibodies to Tissue Transglutaminase Reveals a Low Prevalence of Celiac Disease in Blood Donors with Cryptogenic Hypertransaminasemia
Patients with chronic cryptogenic hypertransaminasemia are at high risk of developing celiac disease (CD). In fact, among the various serological disorders, CD patients at onset frequently present hypertransaminasemia. In this study, we evaluated usefulness and reliability of the new test for antitissue transglutaminase (tTG) in screening for CD as well as in estimating the prevalence of CD in a population of blood donors presenting unexplained hypertransaminasemia at donation. Controls were 180 consecutive healthy donors without hypertransaminasemia and 20 CD patients with known antiendomysial antibody (EmA) positivity. Out of 22,204 blood donors over a period of 2 years, we found 258 subj…
Evaluation by Ultrasound of Abdominal Lymphadenopathy in Chronic Hepatitis C
Objective: Abdominal ultrasound has shown a frequent association between abdominal lymphadenopathy (LA) and chronic liver disease, but contradictory data have been reported on its relationship with the main parameters of hepatic function. The aim of this study was to correlate the prevalence of LA in patients who were chronic hepatitis-anti-hepatitis C virus positive prospectively followed-up over the last 3 years and its relationship with biochemical and histological data. Methods: 136 RIBA II confirmed positive patients with ALT levels >2N were included. None of these had been or was at the time of study on interferon treatment. Ultrasound was performed using a Toshiba SSA 240 A apparatus…
