Abstract The diagnosis of cryptogenic liver disease is made when after extensive evaluations, recognizable etiologies chronic are excluded. In this study, the presence hepatitis C virus (HCV) RNA was tested in peripheral blood mononuclear cells (PBMCs) taken from Iranian patients who although were found negative for plasma HCV and anti‐HCV antibodies, suffered unknown etiology. From September 2007 to March 2010, 69 Tehran with etiology referred our center enrolled present study. PBMCs...

Background: Occult hepatitis C virus (HCV) infection is a new entity described by the presence of HCV-RNA in liver biopsy and/or peripheral blood mononuclear cell (PBMC) specimens, and undetectable levels or absence anti HCV antibodies plasma current laboratory methods. Objectives: To evaluate detection PBMC specimens transplant candidates with cryptogenic cirrhosis reverse transcriptase-nested polymerase chain reaction (RT-nested PCR). Patients Methods: From November 2007 to March 2013, 45...

Fatigue is common in primary biliary cirrhosis (PBC). Altered central serotonergic neurotransmission may be involved its pathogenesis. This multicenter, randomized, double-blind, placebo-controlled, crossover trial evaluated the efficacy of ondansetron, a selective 5-HT3 receptor subtype antagonist, for treating fatigue PBC. A design was chosen, allowing subjects to serve as their own controls—appropriate evaluate fatigue, subjective symptom. Sixty patients with clinically stable PBC,...

Liver transplantation is the global treatment of end-stage liver diseases. Since patients' survival rate has been improved, patient may experience reductions in physical, cognitive, and psychosocial functions after influencing their adherence to care treatment. The transplant complex should be considered when health providers make decisions regarding This qualitative study aimed explore factors self-management among recipients treatment.In this study, 23 interview sessions were carried out...

OBJECTIVES Length of stay is considered an important surrogate for transplant survival rate and resource utilization. Therefore, in the present study, our aim was to determine factors affecting length hospital stay. MATERIALS AND METHODS We retrospectively analyzed records patients who underwent liver at Tehran University Medical Sciences Liver Transplantation Center from March 2014 2016. RESULTS For final analyses, there were 161 adult recipients, including 106 males (65.8%) 55 females...
