Article Synopsis
  • Ferroportin disease is a rare genetic disorder causing excess iron in the body, possibly more common than previously thought, but often underdiagnosed due to high costs and unclear genetic testing criteria.
  • The study developed a scoring system based on various clinical factors to improve screening for this condition, using data from over 1,300 patients to create a weighted score that aids diagnosis.
  • The scoring system showed a sensitivity of 93.6% and is proposed for use in regular clinical practice to help identify and manage patients with ferroportin disease effectively.

Juvenile hemochromatosis is a rare autosomal recessive disease due to variants in the Hemojuvelin (HJV) gene. Although biological features mimic HFE hemochromatosis, clinical presentation is worst with massive iron overload diagnosed during childhood. Our study describes clinical features and results of genetic testing for a group of patients initially referred for a hepcidino-deficiency syndrome and for whom HJV hemochromatosis was finally diagnosed.

Background: Doxorubicin Transdrug (DT), a nanoformulation of doxorubicin, was demonstrated to overcome the chemoresistance of hepatocellular carcinoma (HCC) in preclinical models. Its efficacy and safety were thus investigated in phase I and randomised phase II trials in unresectable HCC.

Patients And Methods: Phase I was a single dose of DT through the hepatic intra-arterial (HIA) route, dose-escalating 3+3 trial, evaluating five-dose levels from 10 to 40 mg/m with maximal tolerated dose (MTD) as primary endpoint.

Introduction: There is still uncertainty regarding the efficacy and optimal modalities of extracorporeal shock wave lithotripsy (ESWL) in the treatment of chronic pancreatitis. The aims of the present study were to assess the safety and the efficacy of ESWL, either alone or followed by therapeutic endoscopic retrograde cholangiopancreatography (adjuvant ERCP) and to determine predictive factors of efficacy, in a real-life setting.

Patients And Methods: This study included all consecutive patients who underwent an ESWL in a single University Hospital between 2001 and 2012.

Background Data: In compensated cirrhotics with early hepatocellular carcinoma (HCC-cirr), upfront liver resection (LR) and salvage liver transplantation (SLT) in case of recurrence may have outcomes comparable to primary LT (PLT).

Objective: An intention-to-treat (ITT) analysis comparing PLT and SLT strategies.

Methods: Of 130 HCC-cirr patients who underwent upfront LR (group LR), 90 (69%) recurred, 31 could undergo SLT (group SLT).

Background: Resection and liver transplantation (LT) are the only curative options for hepatocellular carcinoma in cirrhotic patients (HCC-cirr).

Objective: We tried to define the best primary intention-to-treat strategy in patients undergoing either resection or LT for early single HCC-cirr (≤5 cm).

Methods: From 1990 to 2010, 198 patients with early HCC-cirr underwent either resection (group R, n = 97) or LT (group T, n = 101) as the primary procedure.

Hepatitis E is currently diagnosed after all other causes of hepatitis have been excluded. Moreover, HEV testing is not performed to prevent blood transmission in developed countries. We report here on the case of a patient with acute hepatitis while receiving potentially hepatotoxic medications for autoimmune disorders, with low-level autoimmune markers and negative "standard" viral markers; it was finally determined that he was suffering from transfusion-transmitted hepatitis E.

No treatment is recommended for silent gallstones. The diagnosis of acute cholecystitis is based on clinical and biological signs and on abdominal sonography. Early laparoscopic cholecystectomy is the treatment of choice, except in case of severe (grade III) cholecystitis where a percutaneous cholecystostomy associated with antibiotic therapy is recommended.

Aim: To study predictive factors of thyroid dysfunction associated with interferon-alpha (IFNalpha) therapy in chronic hepatitis C (CHC) and to describe its long-term evolution in a large population without previous thyroid dysfunction.

Methods: We performed a follow-up of thyroid function and detection of thyroid antibodies in 301 patients treated for CHC with IFNalpha from 1999 to 2004.

Results: Thyroid disorder developed in 30/301 (10%) patients with a mean delay of 6 +/- 3.

Article Synopsis
  • The study assessed how well ciprofloxacin and cefotaxime penetrated into bile in patients with blocked bile ducts after receiving antibiotics via IV.
  • Biliary penetration was low for both drugs, with ciprofloxacin showing better, but still inadequate, levels compared to cefotaxime.
  • Common liver function tests did not effectively predict how much of the antibiotics would reach the bile.

Aims: Steatosis may increase oxidative stress, which is counteracted by cellular enzymatic (cytosolic and mitochondrial superoxide dismutases (Cu/Zn-SOD and Mn-SOD), glutathione peroxidase (GPx), catalase) and non-enzymatic antioxidant systems. We aimed to determine, in patients with non-alcoholic fatty liver disease (NAFLD), the level of antioxidant defenses (1) in liver biopsies, to demonstrate the existence of oxidative stress; (2) in erythrocytes and plasma, to determine whether their antioxidant defenses reflect liver oxidative stress.

Methods: Erythrocyte and plasma antioxidant defenses were prospectively studied in two groups of 16 patients: patients with NAFLD and controls.
