    Abstract Background/aims: Portal hypertension complicating liver cirrhosis is associated with vascular resistance, possibly due to overexpression of humoral vasoconstrictors, including endothelin. The study aimed to evaluate the efficacy of serum endothelin-1 levels as a noninvasive predictor of early esophageal rebleeding (within 5 days) following endoscopic treatment.
    Materials and methods: Of the patients presented to the endoscopy unit at Mansoura University Hospital, 50 patients were chosen for this study on the basis of endoscopically proven acute esophageal variceal bleeding consequent to hepatitis C viral infection complicated by liver cirrhosis and portal hypertension. Routine laboratory parameters and serum endothelin-1 levels were assessed prior to endoscopic treatment. Patients were divided into 2 groups depending on the development of early postendoscopic rebleeding. Group A consisted of 16 patients who developed rebleeding, while group B included 34 patients who did not. Statistical analysis was performed to determine the predictors of rebleeding.
    Results: Multivariate logistic regression demonstrated that endothelin-1 level (P < .001) and serum albumin level (P = .04) were independent risk factors for early rebleeding. The most efficient cutoff value for endothelin-1 levels in predicting variceal rebleeding within the 5 days after endoscopic intervention was 65.29, which had an 88.2% specificity, 87.5% sensitivity, 88% accuracy, and area under the curve value of 0.89. In addition, hemoglobin, albumin, and creatinine levels were significantly different between bleeding and nonrebleeding groups (P = .03, P = .014, and P <.001, respectively), as was the duration of hospital stay (P < .001).
    Conclusion: Serum endothelin-1 levels appear to be a reliable, practical, noninvasive predictor of early variceal rebleeding and related comorbidities such as the severity of kidney affection and duration of hospital stay.

    Abstract The RECK gene, a tumor suppressor gene, inhibits angiogenesis, invasion, and tumor metastasis. Epigenetic regulation of the RECK gene constitutes a potent approach to the molecular basis of liver malignancy. This study aims to evaluate the promoter methylation status of the RECK gene and its serum level in patients with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) and the potential association of RECK gene methylation with clinical criteria of HCC. One hundred and fifty-five subjects were included (healthy control [55], chronic HCV patients [55], HCV-related HCC patients [45]). The methylation status of the RECK gene promoter and serum RECK level were investigated by methylation-specific PCR and enzyme-linked immunosorbent assay techniques, respectively. RECK gene promoter hypermethylation was recorded in 46.7% of HCC patients, and 10.9% of HCV patients, but not in control subjects (0%). It was related to RECK protein level, varices, edema, ascites, lymph node metastasis, vascular invasion, and the largest diameter of focal lesions. Meanwhile, it was not associated with focal lesion number nor distant metastasis of HCC. In conclusion, RECK gene promoter hypermethylation is linked to HCV genotype-4-related HCC. Moreover, different degrees of RECK gene promoter methylation are associated with serum RECK level, lymph node metastasis, and vascular invasion, which could prove its pathogenic role in hepatocarcinogenesis in chronic HCV-infected patients.

    Abstract The current study aimed to investigate the diagnostic value of glycated albumin (GA), glycated hemoglobin (HbA1c), and a number of routine biomarkers as noninvasive indicators of liver fibrosis in patients with chronic hepatitis C (CHC). One hundred patients with CHC were subjected to full medical history and examination, in addition to ultrasound-guided liver biopsy and histopathological examination for assessment of liver fibrosis stage. GA and HbA1c values, GA/HbA1c ratio, liver function tests, complete blood count, and alpha fetoprotein (AFP) were determined. A novel noninvasive index, dubbed Fibrosis Prediction Score (FPS), was selected for predicting significant liver fibrosis based on total bilirubin, glycated albumin, platelet count, age, and AFP. A validation study for FPS was applied on archival data which include 66 diabetics' patients. The FPS had area under the curve (AUC) of 0.92 for classification of patients with significant fibrosis with 81% sensitivity and 95% specificity. The AUCs of FPS in predicting advanced fibrosis and cirrhosis were 0.86 and 0.82, respectively. Comparison of AST-to-platelet ratio index (APRI) and FIB-4 with FPS indicated increased sensitivity and specificity of FPS over APRI and FIB4 in both significant and advanced fibrosis. FPS has a good sensitivity and specificity for prediction of significant and advanced liver fibrosis in patients with CHC.

    Abstract Background: Occult hepatitis B virus infection (OBI) frequently occurs in patients with chronic hepatitis C (CHC) infection, but the influence of OBI on CHC outcome is still uncertain. The aim of the present study was to clarify the clinical and pathological characteristics of OBI in CHC-related hepatocellular carcinoma (HCC).
    Patients and methods: DNA was obtained from serum and tumor tissue of patients with hepatitis C virus (HCV)-related HCC with negative HBsAg and from patients with HCV-related liver cirrhosis. HBV-DNA was detected using qPCR. Clinicopathological features were compared between patients with HCC with and without OBI.
    Results: On the basis of positive serum and tissue HBV-DNA typing, the overall frequency of OBI was 50% in patients with HCV-related HCC. HBV genotype D was the most dominant, constituting 35.3% of HCC cases. Almost 80% of patients with OBI had anti-HBc, whereas 20% of patients had no serological markers. Tissue HBV-DNA showed significant association with positive serum HBV-DNA, anti-HBc, and genotype D. There were no clinical differences between patients with HCC with and without OBI; however, patients with OBI tended to be younger. HCC cases with positive OBI were significantly associated with positive anti-HBc antibodies and late histological grades (3-4). Multivariate logistic regression analysis revealed that the presence of OBI was a predictor of more advanced HCC histological grades in patients with HCV infection.
    Conclusion: OBI was detected in 50% of HCV-infected patients with HCC. OBI was strongly associated with the presence of anti-HBc antibodies. Patients with HCC with positive OBI were younger and had more advanced HCC histological grades.

    Abstract This trial compared the rate and time of viral clearance in subjects receiving a combination of nitazoxanide, ribavirin, and ivermectin plus Zinc versus those receiving supportive treatment. This non-randomized controlled trial included 62 patients on the triple combination treatment versus 51 age- and sex-matched patients on routine supportive treatment. all of them confirmed cases by positive reverse-transcription polymerase chain reaction of a nasopharyngeal swab. Trial results showed that the clearance rates were 0% and 58.1% on the 7th day and 13.7% and 73.1% on the 15th day in the supportive treatment and combined antiviral groups, respectively. The cumulative clearance rates on the 15th day are 13.7% and 88.7% in the supportive treatment and combined antiviral groups, respectively. This trial concluded by stating that the combined use of nitazoxanide, ribavirin, and ivermectin plus zinc supplement effectively cleared the SARS-COV2 from the nasopharynx in a shorter time than symptomatic therapy.

    Abstract Background: Limited experimental and clinical evidence suggests a potential role for sofosbuvir/daclatasvir in treating COVID19. We aim to evaluate the efficacy of generic sofosbuvir/daclatasvir in treating COVID-19 patients with pneumonia.
    Research design and methods: This multicenter prospective study involved 174 patients with COVID-19. Patients were randomized into two groups. Group A (96 patients) received sofosbuvir (400 mg)/daclatasvir (60 mg) for 14 days in combination with conventional therapy. Group B (78 patients) received conventional therapy alone. Clinical, laboratory, and radiological data were collected at baseline, after 7, 14, and 28 days of therapy. Primary endpoint was rate of clinical/virological cure.
    Results: A lower mortality rate was observed in group (A) (14% vs 21%, P = 0.07). After 1 month of therapy, no differences were found in rates of ICU admission, oxygen therapy, or ventilation. Additionally, a statistically significant shorter duration of hospital stay (9% vs 12%, P < 0.01) and a faster achievement of PCR negativity at day 14 (84% versus 47%, P < 0.01) were noticed in group (A).
    Conclusion: Adding sofosbuvir/daclatasvir to conventional therapy of COVID-19 is promising. Their use is associated with shorter hospital stay, faster PCR negativity and may be reduced mortality.

    Abstract Background and study aims: Chronic hepatitis is characterised by increased regenerative cell proliferation, a process that makes cells more susceptible to gene mutations and development of hepatocellular carcinoma (HCC). Evaluation of the proliferative index could be a useful tool for identifying patients at risk for HCC. The current study was planned to evaluate hepatocyte proliferation in predominant causes of chronic liver disease in an attempt to investigate predictors of proliferation.
    Patients and methods: This study included 84 patients with chronic liver diseases, and they were classified into three groups: chronic hepatitis C (50 patients), non-alcoholic steatohepatitis (NASH) (20 patients) and chronic hepatitis B (14 patients). All cases were investigated by liver function tests, polymerase chain reaction (PCR) hepatitis C virus (HCV) and hepatitis B virus (HBV), routine abdominal ultrasound and liver biopsy with detection of the proliferative index using the monoclonal antibody MIBI-Ki-67.
    Results: The proliferative index was significantly higher in the chronic hepatitis C group than in the chronic hepatitis B group (P value=0.007). There were significant correlations of the Ki-67 index in both zone 1 and zones 2 and 3 with alanine aminotransferase (ALT), aspartate aminotransferase (AST) and histological activity index (HAI) score. Using the multiple regression analysis on the variables affecting proliferation, it was found that predictors of zone 1 proliferation were the following variables: ALT, age, AST and aetiological factor, in that order.
    Conclusion: HCV aetiology had significantly higher proliferation index, whereas NASH had the least. Increased HAI score is associated with higher proliferative index in either zone 1 or zones 2 and 3. Predictors of proliferation index in zone 1 were ALT, age, AST and aetiological factor.

    Abstract Introduction and aim: Hepatitis C virus (HCV) infection is a global medical problem. HLA -DRB1 alleles have an important role in immune response against HCV. The aim of this study is to clarify the contribution of HLA -DRB1 alleles in HCV susceptibility in a multicentre family-based study.
    Material and methods: A total of 162 Egyptian families were recruited in this study with a total of 951 individuals (255 with chronic hepatitis C (CHC), 588 persons in the control group(-ve household contact to HCV) and 108 persons who spontaneously cleared the virus (SVC). All subjects were genotyped for HLA -DRB1 alleles by SSP-PCR and sequence based typing (SBT) methods.
    Results: The carriage of alleles 3:01:01 and 13:01:01 were highly significant in CHC when compared to that of control and SVC groups [OR of 3 family = 5.1289, P
    Conclusions: It was concluded that among the Egyptian families, HLA-DRB1*030101, and DRB1*130101 alleles associated with the risk of progression to CHC infection, while DRB1*040101, DRB1*040501, DRB1*7:01:01and DRB1*110101 act as protective alleles against HCV infection.

    Abstract Background and aim: Extremely poor prognosis in hepatocellular carcinoma (HCC) patients with progressing disease was denoted by vascular invasion. Cytokeratin 18 (CK18) has been shown to be overexpressed in hepatocellular carcinoma so it is a valuable tumor marker; however, its role in vascular invasion is still unclear. This study aimed to predict CK18 as a predictive marker for macrovascular malignant invasion.
    Methods: The present study was conducted on three groups of patients: group I included 91 HCC patients without macrovascular invasion, group II included 34 HCC patients with radiological evidence of vascular invasion, and group III included 110 control individuals subdivided into IIIA as healthy blood donors and IIIB as post-HCV cirrhotic patients without HCC.
    Results: ROC curve of M30 fragments of CK18 was constructed for discrimination between HCC with and without macrovascular invasion. Optimum cutoff value was 304.5 ng/mL (AUC = 0.997, P < 0.001), sensitivity (100%) and specificity (98.8%). Regression analysis was conducted for prediction of macrovascular invasion within HCC patients. The following variables: higher levels of AST, M30, bilirubin, and AFP, lower levels of serum albumin, larger tumor size, child B score, and multiple lesions were associated with vascular invasion in univariate analysis. While in multivariate analysis, higher levels of AST and bilirubin and elevated levels of M30 and AFP serum were considered independent predictors for macrovascular invasion in HCC patients.
    Conclusion: The present study suggests that increased M30 fragments of CK18 levels may be useful as a possible marker of early tumor invasiveness.
