Hepatitis B (HBV) infections continue to occur in adult hemodialysis units. Occult HBV infection (serum hepatitis B surface antigen [HBsAg] negative but HBV DNA positive) may be a contributing factor in these patients. This study was designed to (1) investigate the prevalence of occult HBV infection in hemodialysis patients and (2) compare the prevalence of occult HBV infection among hepatitis C (HCV)-positive and HCV-negative hemodialysis patients. The study included 138 patients on chronic hemodialysis. Eighty-four patients were HCV positive and 54 were HCV negative. HBV DNA testing was performed by polymerase chain reaction. We also recorded general characteristics of the patients, duration of hemodialysis, and serum alanine aminotransferase and aspartate aminotransferase levels. Twenty-one (15.2%) of the 138 hemodialysis patients were HBV DNA positive. Nine (16.6%) of the 54 anti-HCV antibody negative hemodialysis patients were HBV DNA positive. Twelve (14.2%) of the 84 anti-HCV antibody positive patients were HBV DNA positive. The prevalence in anti-HCV Ab positive and negative hemodialysis patients were same (P > .05). Hemodialysis duration, demographic features, and biochemical parameters were not significantly different in patients with and without occult HBV infection in both HCV-positive and -negative hemodialysis patients (P > .05). HCV positivity is not a contributing factor to occult HBV infection in hemodialysis patients. None of the parameters tested help to distinguish patients with occult HBV infection from those who are HBV DNA negative.
The objective of this study was to investigate the effects of types of dialysis treatments on hepatitis C virus infection and the epidemiologic properties of hepatitis C virus (HCV) infection at three Baskent University hospitals, in Ankara, Adana, and Izmir, Turkey, in 655, 326, and 118 patients with end-stage renal disease, respectively. One hundred thirty patients with HCV viremia among 271 patients with end-stage renal disease seropositive for HCV were included in this cross-sectional study. HCV RNA-positive patients were classified according to the renal replacement therapies (hemodialysis or continuous ambulatory peritoneal dialysis), and viral load, transaminase levels, and distribution of genotypes were compared between these subgroups. In the continuous ambulatory peritoneal dialysis group, 26 of 165 patients (16%) were serum anti-HCV positive, and 11 of 26 patients (42%) were serum HCV RNA positive. Twenty-six percent of the patients undergoing hemodialysis were anti-HCV positive, and 49% were HCV RNA positive. The prevalence of genotype 1b was 68% and 73% for patients in the continuous ambulatory peritoneal dialysis and hemodialysis groups, respectively. No significant differences were found between the genotype 1b and the non-1b groups or between different dialysis types with regard to age and sex and serum aspartate transaminase, alanine aminotransferase, and HCV RNA levels. We conclude that HCV seropositivity may differ between different types of dialysis treatments, although viral load and genotypes may be similar in persons with end-stage renal disease and those without.
Chylous ascites is the accumulation of lipid-rich lymph in the peritoneal cavity. The usual cause in adults is lymphatic obstruction or leakage caused by malignancy. Non-malignant causes include postoperative trauma, cirrhosis, tuberculosis, pancreatitis and filariasis. A variety of treatment options have been proposed for the management of chylous ascites; however, their effectiveness in idiopathic or primary form is unknown. Here we report a case of chylous acid rapidly resolved with the treatment of fasting, total parenteral nutrition and somatostatin analogue.
Experience with endoscopic retrograde cholangiopancreatography in the pediatric population is limited. The aim of this study was to evaluate the outcomes of ERCP in the pediatric population performed by adult gastroenterologists with standard duodenoscopes. This study is a structured retrospective review of endoscopic reports, computerized and paper medical records, and radiographic images of patients under the age of 18 who underwent ERCP for any indication at a tertiary referral centre. Data regarding demographic characteristics and medical history of patients, indications, technical success rate, final clinical diagnosis, and complications were analyzed. Forty-eight children with a mean age of 13 years (range 2–17) underwent a total of 65 ERCPs. The indications of ERCP were as follows; suspected choledocholithiasis (55 %), post-liver transplantation anastomotic biliary strictures (21 %), post-surgical bile duct injury (10 %), choledochal cyst (2 %), recurrent or chronic pancreatitis (10 %), and trauma (2 %). The cannulation success rate in the overall procedure was 93.8 %. Therapeutic interventions were performed in 70.7 % of patients. Post ERCP pancreatitis was the most common complication occurring in 9.2 % of patients, and no procedure related mortality occurred. When performed by well-trained adult gastroenterologists, the use of endoscopic retrograde cholangiopancreatography with standard duodenoscopes is safe in pediatric population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
