Abstract Background/Aims: We aimed to describe spontaneous short-term hepatitis B Virus (HBV) DNA level fluctuations and to assess the usefulness of quantitative HBsAg (qHBsAg) in Tunisian patients with HBeAg-negative chronic HBV infection.Patients and methods: We included 174 treatment-naïve patients with chronic HBeAg-negative HBV. A one-year prospective follow-up was carried out with serial determinations of HBV DNA, alanine aminotransferase levels and qHBsAg. Patients were classified into three groups: inactive carriers (G1), patients with HBeAg negative chronic hepatitis B (CHB) (G2) and patients with indeterminate state (G3). For this latter group, a liver biopsy was indicated.Results: Only genotype D was detected. During the follow-up, 21.6% and 19.5% of patients with low initial (<2000 IU/mL) and intermediate viral load (2000-20000 IU/mL), experienced a subsequent increase in their HBV DNA levels above 2000 and 20000 IU/mL, respectively. Significant variations of HBV DNA levels (≥0.5 log10 IU/mL) were observed in 61.1% of patients at 6 months-interval. Among the 174 patients, 89 (51.1%) belonged to G1, 33 (19%) to G2 and 52 (29.9%) to G3. Fourteen patients have undergone liver biopsy, among whom 7 (50%) showed moderate to severe liver disease. Combination of HBV DNA <2000 IU/mL and qHBsAg <832 IU/mL excluded CHB in 98.4% of cases.Conclusions: This study highlights the large short-term HBV DNA fluctuations in Tunisian patients with HBeAg negative chronic HBV of genotype D. HBV DNA < 2000 IU/mL along with qHBsAg < 832 IU/mL excluded CHB in 98.4% of cases. Significant proportion of patients with indeterminate state within genotype D would have HBeAg negative CHB.

Introduction. Arteriovenous fistula is one of the complications that can occur during percutaneous liver biopsy. Hepatic arterio-venous fistula with chronic bleeding from the puncture site on the skin is extremly rare complication following percutaneous liver biopsy. Case report. The case represents a 35-year-old woman with secondary anemia caused by chronic bleeding at the site of a granuloma caused by a previous liver biopsy done 7 years ago. The patient was examined and treated for several years due to anemic syndrome. The pathological communication between the right hepatic vein, the anterior sectional branch of the portal vein and the posterior arterial sectional branch was detected on a CT scan, and proven by fistulography. Due to the failed embolization, a laparotomy was performed, where a tumor mass was found in the VI and VII segment of the liver, which communicates with the skin. Tumor mass was removed by atypical resection of VI and VII liver segments. Due to hemorrhage, re-exploration was performed, where bleeding was found from the surface of the resected liver parenchyma. Two weeks after the last operation, the patient was released for home treatment. Conclusion. Although percutaneous liver biopsy is a safe procedure, the complication in the form of bleeding occurs in less than 25% of cases and with spontaneous cessation. In our presentation, there was a complicated intrahepatic arteriovenous-portal fistula with the formation of communication with the puncture site on the skin. This is the first case of complications of this type after percutaneous liver biopsy.

Abstract Purpose The purpose of this study was to evaluate the diagnostic performance of novel ultrasound technology normalized local variance (NLV) and the standard deviation of NLV (NLV-SD) using different ROIs for hepatic steatosis in patients with metabolic-associated fatty liver disease (MAFLD) and to identify the factors that influence the NLV value and NLV-SD value, using pathology results as the gold standard. Methods We prospectively enrolled 34 consecutive patients with suspected MAFLD who underwent percutaneous liver biopsy for evaluation of hepatic steatosis from June 2020 to December 2020. All patients underwent ultrasound and NLV examinations. NLV values and NLV-SD values were measured using different ROIs just before the liver biopsy procedure. Results The distribution of hepatic steatosis grade on histopathology was 4/19/6/5 for none (< 5%)/ mild (5–33%)/ moderate (> 33–66%)/ and severe steatosis (> 66%), respectively. The NLV value with 50-mm-diameter ROI and NLV-SD value with 50-mm-diameter ROI showed a significant negative correlation with hepatic steatosis (spearman correlation coefficient: − 0.449, p = 0.008; − 0.471, p = 0.005). The AUROC of NLV (50 mm) for the detection of mild, moderate, and severe hepatic steatosis was 0.875, 0.735, and 0.583, respectively. The AUROC of NLV-SD (50 mm) for the detection of mild, moderate, and severe hepatic steatosis was 0.900, 0.745, and 0.603, respectively. NLV (50 mm) values and NLV-SD (50 mm) values between two readers showed excellent repeatability and the intraclass correlation coefficient (ICC) was 0.930 (p < 0.001) and 0.899 (p < 0.001). Hepatic steatosis was the only determinant factor for NLV value and NLV-SD value (p = 0.012, p = 0.038). Conclusion The NLV (50 mm) and NLV-SD (50 mm) provided good diagnostic performance in detecting the varying degrees of hepatic steatosis with great reproducibility. This study showed that the degree of steatosis was the only significant factor affecting the NLV value and NLV-SD value.
