Primary hyperoxaluria type 1 (PH1) is a rare, autosomal recessive disease, caused by the defect of AGXT gene encoding hepatic peroxisomal alanine glyoxylateaminotransferase (AGT). This enzyme is responsible for the conversion of glyoxylate to glycine. The diagnosis of PH1 should be suspected in infants and children with nephrocalcinosis or nephrolithiasis. Early diagnosis and treatment is crucial in preventing disease progression to end stage kidney disease (ESKD). In this study, AGXT gene sequence analyses were performed in 82 patients who were clinically suspected (hyperoxaluria and nephrolithiasis or nephrocalcinosis with or without renal impairment) to have PH1...

The incidence of hepatocellular carcinoma (HCC) in patients with thalassemia is on the rise. The 2 well recognized HCC risk factors in thalassemia are iron overload and chronic viral infection with hepatitis C. The carcinogenicity of iron is related to its induction of oxidative damage, which results in genotoxicity, and to immunologic dysregulation, which attenuates cancer immune surveillance. Chronic hepatitis B and C infections lead to necroinflammation, which can prompt progression to HCC, but an independent role of hepatitis B virus in hepatic carcinogenesis among patients with thalassemia has not been demonstrated...

Hepatitis E is an emerging viral disease in developed countries, with sporadic cases occasionally linked to the consumption of raw or undercooked pork, wild boar or deer meat. Cases due to transfusion or transplantation have also been reported. In developed countries, hepatitis E is considered a zoonosis and pig is the main reservoir. In the last few years, several studies conducted in Europe reported variable seroprevalence rates among the general population, ranging between 0.26% and 52.5%. A higher seroprevalence was described among workers who come in contact with pigs...

BACKGROUND Right lobe living donor liver transplantation (LDLT) remains the most common form of liver transplantation in Asia. However, reconstruction of the venous outflow in a right liver allograft may pose technical difficulties if hepatic venous variations are present. Recently, much emphasis has been given to the reconstruction of large and multiple inferior right hepatic veins (IRHVs). The method of reconstructive technique, type of vascular grafts, and the outcome after the procedure have been a point of debate...

BACKGROUND: Pancreatitis is a serious complication after cardiac surgery and can lead to significant morbidities and mortality. The incidence of pancreatitis is even higher in patients undergoing heart transplantation than in those undergoing other cardiac surgeries. Nevertheless, the clinical presentations of pancreatitis are frequently atypical in these patients. CASE PRESENTATION: We report a heart recipient who was complicated with acute right heart failure initially after orthotopic heart transplantation and developed devastating unanticipated hemorrhagic pancreatitis 1 month after the transplantation...

Viral hepatitis B still represents a major epidemiological issue worldwide. After recombinant vaccine administration, a titer of anti-HBs antibodies ≥ 10 IU/L has long been considered to be seroprotective. Persons without this antibody level after complete vaccination are referred to as non-responders. A progressive decline in anti-HBs levels over years is also commonly seen in responders. Recently, there has been increasing evidence that the titer of anti-HBs ≥ 10 IU/L does not provide 100 % protection against infection and clinically manifest illness...

BACKGROUND: Guidelines recommend that patients with hepatitis C virus (HCV)-related liver disease be treated for HCV before liver transplant (LT) to eliminate the virus prior to surgery. However, the unpredictability of donor organ availability may limit treatment duration. Interruption of HCV treatment with resumption post-LT is one potential solution which has not been investigated widely. METHODS: Patients from 5 clinical centres included in the large, national, noninterventional Hepa-C registry who started treatment with direct-acting antiviral agents (DAAs) while awaiting LT were identified retrospectively and followed up prospectively...

PURPOSE OF REVIEW: The current review highlights recent advances in treatment of chronic hepatitis C virus infection using new classes of agents, direct-acting antivirals (DAAs), with a focus on the evidence for their use in the setting of chronic kidney disease (CKD) stages 4-5, hemodialysis, and kidney transplantation. RECENT FINDINGS: DAA agents target-specific proteins involved in the hepatitis C virus life cycle and interrupt viral replication. Sustained virologic response, a marker of viral eradication, occurs in more than 90% of patients treated with DAA agents in the general population...

: The availability of oral direct-acting antiviral (DAAs) has altered the hepatitis C virus (HCV) treatment paradigm for both pre- and post-liver transplant (LT) patients. There is a perceived trade-off between pre- versus post-LT treatment of HCV-treatment may improve liver function but potentially decrease the likelihood of a necessary LT. Our objective was to identify LT-eligible patients with decompensated cirrhosis who would benefit (and not benefit) from pre-LT treatment based on their MELD scores...

BACKGROUND: Recurrent hepatocellular carcinoma after a patient's initial therapy, whether it is transplantation, resection, or ablation, remains a challenging clinical problem. Since recurrence occurs in 70% of all initially treated disease within 5 years, optimal management to treat this recurrence is needed. Currently, a bias exists toward mono-therapy (i.e., ablation alone, hepatic arterial therapy alone, or sorafenib therapy alone) instead of concurrent sequential therapy-as is common in other primary and metastatic disease to the liver...

BACKGROUND: Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide and the third most common cause of cancer-related deaths. Hepatic resection and liver transplantation are considered to be the preferred treatment for HCC. However, as novel therapeutic options such as image-guided locoregional therapies have emerged and been refined, the manner in which HCC is treated has changed dramatically compared with what it was considered just 2 decades earlier. SUMMARY: This study reviews the current results of various image-guided locoregional therapies for treating HCC, especially focusing on thermal ablative and transarterial techniques...

BACKGROUND: Hepatitis C is a significant cause for end-stage liver diseases and liver transplantation which affects approximate 3% of the global populations. Despite the present of several direct antiviral agents in the treatment of hepatitis C, the standard treatment for HCV is accompanied by several drawbacks such as adverse side effects, high pricing of medications and the rapid emerging rate of resistant HCV variants. OBJECTIVES: To discover potential inhibitors for HCV helicase through an optimized in silico approach...

PURPOSE: The spleen presents numerous functions, including the production of immunoglobulins and blood filtration, removing microorganisms and cellular debris. The spleen also has anatomical and functional relationship with the liver, but there are few studies on this topic. The aim of this study was to assess the effect of splenectomy and autologous spleen transplantation on both filtering functions of spleen and acetaminophen-induced hepatotoxicity. MATERIALS AND METHODS: Fifty-two BALB/c mice were randomized into four groups: splenectomized; splenectomy and splenic autotransplantation in the greater omentum; sham operated control; and non-operated control...

Many patients develop new-onset diabetes after kidney transplantation (NODAT). Its incidence and epidemiology are unknown in the Saudi population. We aimed to study the incidence, epidemiology, and outcomes of kidney transplant recipients who developed NODAT. This is a retrospective study of all adults who received kidney transplant between January 2003 and December 2009. NODAT was defined according to the criteria outlined in the 2003 International Consensus guidelines. A total of 500 patients were included in this study, 54% were male patients...

Hepatic metastases are one of the most important prognostic factors for survival among patients affected by gastrointestinal neuroendocrine tumors (NETs). The present study aims to evaluate the impact of surgery, including hepatic resection or orthotopic liver transplantation (OLT), on the outcome of patients affected by hepatic metastases from NETs, in terms of overall survival (OS). In this multicentric retrospective study, data was collected on 26 patients, who underwent surgery for hepatic metastases from NETs in two Italian University Clinics between January 1990 and December 2012; of which, 22 patients underwent hepatic resective surgery and 4 patients OLT...

BACKGROUND AND AIMS: The AFP model was shown superior to Milan criteria for prediction of HCC recurrence after liver transplantation in a French population. Our aim was to test the AFP model in a non French, post-hepatitic cirrhosis-based population of HCC candidates. METHODS: 574 patients transplanted for HCC in 4 Italian centres were studied. AFP score was assessed at last evaluation before LT. Probabilities of recurrence and survival were estimated by the log rank test or competing risk analysis and compared according to the AFP model...

Non-alcoholic steatohepatitis (NASH) is characterized by liver steatosis and inflammation. Currently, the underlying mechanisms leading to hepatic inflammation are not fully understood and consequently, therapeutic options are poor. Non-alcoholic steatohepatitis (NASH) and atherosclerosis share the same etiology whereby macrophages play a key role in disease progression. Macrophage function can be modulated via activation of receptor-ligand binding of Notch signaling. Relevantly, global inhibition of Notch ligand Delta-Like Ligand-4 (DLL4) attenuates atherosclerosis by altering the macrophage-mediated inflammatory response...

Chronic hepatitis C is a major reason for development of cirrhosis and hepatocellular carcinoma and a leading cause for liver transplantation. The development of direct-acting antiviral agents lead to (pegylated) interferon-alfa free antiviral therapy regimens with a remarkable increase in sustained virologic response (SVR) rates and opened therapeutic options for patients with advanced cirrhosis and liver graft recipients. This concise review gives an overview about most current prospective trials and cohort analyses for treatment of patients with liver cirrhosis and liver graft recipients...
