Using sevoflurane inhalation sedation or sleep within dental treatment: the tiny assessment.
Hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) incidence will be diminishing due to use of direct acting antiviral agents (DAA), but there is still constant risk for HCC development. Elevated serum g-glutamyl transpeptidase (GGT) activity is associated with increased risk of liver cancer. In our study we tried to determine whether change in GGT activity may be useful in identifying patients with elevated risk of HCC development after DAA treatment.

The study population consisted of 111 patients with chronic hepatitis C (CHC) treated with DAA. Laboratory tests [alanine aminotransferase (ALT), GGT, a-fetoprotein (AFP)] and liver stiffness measurement (using FibroScan) were performed at the beginning and at the end of therapy.

Pre-treatment ALT activity, GGT activity and AFP concentration in patients with CHC were directly associated with the stage of liver fibrosis. Elimination of HCV after DAA treatment caused significant reduction in serum GGT activity and was not associated with pre-treatment liver fibrosis. AFP concentration was significantly lower after treatment. It was observed regardless of pre-treatment AFP concentration, but the largest reduction was demonstrated in the group of patients with advanced fibrosis. In multivariate analysis there was no significant difference in GGT activity after treatment only in patients with pre-treatment normal AFP concentration and advanced liver fibrosis.

Patients who after achieving a sustained virological response (SVR) did not lower both AFP concentration and GGT activity may have higher risk of HCC development. Special monitoring may be required in patients with advanced liver fibrosis and normal AFP concentration before treatment.

Intrahepatic covalently closed circular DNA (cccDNA) is the main cause of hepatitis B virus (HBV) persistence. Therefore, a noninvasive serum biomarker that can reflect intrahepatic cccDNA is required for evaluation of HBV virological, biochemical activity and therapeutic response. Aim of the study was to assess serum hepatitis B pregenomic RNA in low viremia patients (HBV DNA < 2000 IU/ml) and high viremia (HBV DNA > 2000 IU/ml).

This study was carried out on two groups of chronic hepatitis B patients group A - 40 patients with low viremia (HBV DNA < 2000 IU/ml); group B - 40 patients with high viremia (HBV DNA > 2000 IU/ml when diagnosed). They were assessed before treatment and after 6 months of treatment (entecavir 0.5 mg/24 h). Serum HBV pregenomic RNA was quantified using RT-PCR.

Pregenomic RNA (pgRNA) was significantly lower in group A than in group B (before treatment). Moreover, it was significantly lower after 6 months of treatment than before treatment in group B. A significant positive correlation was observed between pgRNA and HBV DNA in groups A and B (before treatment); however, after 6 months of treatment of group B patients, although 35 patients had undetectable HBV DNA, they showed detectable levels of serum pgRNA and pgRNA > 4000 IU/ml was associated with virological and biochemical activity.

Serum HBV pregenomic RNA might be a promising marker for assessment of HBV virological, biochemical activity and evaluating therapeutic responses.

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, with poor treatment outcomes often because of delayed diagnosis. The aim of this study was to assess the co-incidence of cirrhosis, alcohol abuse, hepatitis B virus (HBV) or hepatitis C virus (HCV) infection and fatty liver disease in patients in the population of north-eastern Poland, to analyse the usefulness of α-fetoprotein (AFP) in the diagnosis of HCC and to assess the effectiveness of HCC treatment in this group.

The study involved 104 patients diagnosed with HCC. The age, sex, comorbidities, HCC risk factors and levels of AFP were analysed. The effect of antiviral therapy of HCV and HBV on HCC development was observed and the effectiveness of therapies used in the treatment of HCC was assessed.

Over 90% of patients with HCC were older than 45 years. The incidence of HCC was higher in men than in women. Patients with HCC were also diagnosed with cirrhosis (72%), alcohol abuse (35%), HCV infection (35%), HBV infection ufficient screening for HCC. Partial hepatectomy and radiofrequency ablation show comparable effectiveness in the treatment of HCC.
Ultrasound surveillance for hepatocellular carcinoma (HCC) among cirrhotic patients is the currently used modality but it is operator dependent. Combining a tumor marker with ultrasound may improve sensitivity for early HCC detection. Our aim was to assess the galectin-3 level among HCC and cirrhotic patients on top of chronic hepatitis C to evaluate its possible role as a tumor marker for HCC surveillance among cirrhotic patients.

The study was conducted on 160 subjects. They were grouped as follows group 1 40 patients with HCC secondary to liver cirrhosis on top of chronic hepatitis C; group 2 40 patients with cirrhosis secondary to chronic hepatitis C; group 3 40 patients with chronic hepatitis C without advanced fibrosis; group 4 40 healthy controls. Serum galectin-3 levels were determined in all subjects using ELISA.

Serum galectin-3 level was significantly higher in HCC patients than in those with chronic hepatitis C (
< 0.001). Proteasomal inhibitor Also it was significantly higher among cirrhotic patients than in patients with chronic hepatitis C (
< 0.001). But on comparing HCC patients with cirrhotic patients, serum galectin-3 levels were not significantly different (
= 0.926).Conclusions Galectin-3 levels cannot be used as an additional method for surveillance of HCC among cirrhotic patients.

Data regarding hepatocellular carcinoma (HCC) recurrence after directly acting antivirals for hepatitis C are contradictory. Our aim was to study the HCC recurrence in patients who received directly acting antivirals after tumor ablation.

This retrospective study included all Child-Pugh A and B patients with hepatitis C related < 5 cm single or up to 3 HCC without any vascular or extrahepatic involvement whose lesions were managed using microwave or radiofrequency ablation at the Internal Medicine Department of Alexandria Faculty of Medicine, in the period from 1 January 2016 to 31 December 2016, and then received directly acting antivirals.

Data from 52 patients were analyzed. Throughout the 2 years from ablation, 42.3% of patients experienced tumor recurrence (22 out of 52 patients). In addition, two subjects died and 4 subjects were lost to follow-up before any tumor recurrence.

Although our study included both modified Child-Pugh A and B patients and included lesions up to 5 cm treated using thermal ablation, the 2-year HCC recurrence rate was similar to that previously reported after surgical resection or radiofrequency ablation of lesions up to 3 cm in Child-Pugh A patients before development of directly acting antivirals.

To investigate the efficacy and safety of Abexol and atorvastatin in patients with non-alcoholic fatty liver disease (NAFLD).Material and methods The present study had a monocentric, randomized, double-blinded, comparative design with 4 parallel groups - group 1 (Abexol), group 2 (atorvastatin), group 3 (combined therapy) and group 4 (placebo) - to which dietary recommendations and physical activity practice were provided twice a day, for 24 weeks. Significant changes in the ultrasound analysis of the liver were considered a primary efficacy variable. Insulin resistance improvement (HOMA2-IR) was considered as a co-primary efficacy criterion. Significant changes in the serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), lipid profile variables and the anthropometric variables were evaluated as secondary variables of effectiveness. Statistical analysis of all data was according to the intention to treat method.

The groups were statistically homogeneous at baseline conditions. At the end of the 6 months of treatment about 50% of the patients in all groups showed a decrease of at least one degree in echogenicity, while the rest remained the same. There were no significant changes in the values of liver enzymes or anthropometric variables evaluated. Treatment with atorvastatin and combined therapy significantly reduced levels of low-density lipoprotein-cholesterol (LDL-C) and total cholesterol. The treatments were safe and well tolerated, although in the atorvastatin group the number of adverse events reported was greater than in the rest of the groups.

Abexol and atorvastatin showed comparable efficacy and safety in patients with NAFLD, with advantages for treatment with atorvastatin with respect to its effects on the lipid profile of these patients.

Azathioprine (AZA) is an important steroid-sparing drug in the management of autoimmune hepatitis (AIH). Avoidance of its adverse events that could be severe and carry a risk of mortality in a few cases is important, preferably with cheap and easy assessments that could be feasible in developing countries with the unavailability of molecular assays. Assessment of thiopurine methyltransferase (TPMT), the key enzyme for the inactivation of AZA, as a predictor of AZA toxicity had been a matter of conflict. This work aimed to study the role of TPMT serum level assessment and other host-, disease-, and treatment-related factors in predicting AZA toxicity.

Sixty-six children with AIH, divided into two groups, were recruited. Group 1 included twelve children with AZA toxicity and group 2 included fifty-four children without AZA toxicities. Both groups were compared for demographic, clinical, laboratory, histopathological, and treatment-related factors, and serum TPMT level, measured by ELISA.

TPMT serum level was comparable in both groups (
