  Background and Objective: Vitamin D, considered as a systemic hormone and important immune modulator, has emerging roles in fibrogenesis, cell cycle arrest and cancer development. The objective of this study was to investigate the association between the Vitamin D Receptor (VDR) gene polymorphisms and hepatocellular carcinoma (HCC) development and severity in Egyptians with Chronic Hepatitis B (CHB). Methods: Two hundred and eighty-five adult consecutive outpatients were enrolled, of which 108 patients with CHB and HCC, 92 patients with CHB without HCC and 85 patients with HCC without CHB. Evaluation of clinicopathological characteristics of HCC was done. Genotyping of VDR gene at TaqI, BsmI, ApaI and FokI was also performed. Results: FokI TT genotype prevalence and T allele frequency were higher in HCC patients than those without HCC. Patients carrying FokI TT genotype had significantly higher risk for HCC (p <0.05) after using FokI CC genotype as a reference and adjusting other covariates including age, gender, CHB infection time, family history of cancer and serum ∞-fetoprotein levels. Also, patients carrying FokI TT genotype had advanced disease stage of cancer, liver cirrhosis, lymph node metastasis. Conclusion: Only the SNPs of VDR gene at FokI locus (C>T) could be used as a molecular marker predicting the risk and evaluating the severity of HCC in Egyptian patients infected with CHB. Polymorphism at FokI locus was associated with increased HCC susceptibility and has a significant role in the determination of its clinicopathological characteristics.

  Background and Objective: MicroRNAs had been implicated in several malignancies. Abnormal circulating microRNA-1246 expression had been detected in HCC patients in an expanding number of studies. However, the information in literature describing the pertinent ramifications of miR-1246 in early-stage HCCs are rare and heterogeneous. This study was designed to assess the diagnostic accuracy of serum miR-1246 level in early-stage HCV-related HCC patients contrasted with chronic hepatitis C (CHC), liver cirrhosis (LC) and healthy control (HC). Materials and Methods: Two hundred HCV outpatients were doled out into 3 groups, HCC group (n = 100), CHC group (n = 30) and LC group (n = 70). Another hundred (100) age- and sex-matched healthy controls (HC) were likewise enlisted. The serum expression level of miR-1246 (by quantitative Real-Time PCR), AFP and prothrombin induced by vitamin K absence-II (PIVKA-II) were tested. Results: In HCC patients, in contrast to AFP, the serum expression levels of PIVKA-II and miR-1246 were statistically significantly increased discriminating HCC patients and early-stage HCCs not only from non-HCC patients (CHC, LC) yet additionally from HC. PIVKA-II and miR-1246, either individually or combined, had excellent diagnostic accuracies and performances as demonstrated by their ROCs and high AUCs >0.7. This serum over-expression positively correlated with the clinicopathological characteristics of both HCC and non-HCC patients. Conclusion: Serum miR-1246 level was significantly higher in HCC patients compared with non-HCC and HC and reliably discriminate early-stage HCV-related HCCs particularly when combined with PIVKA-II.

  The major challenge in inflammatory bowel disease is to achieve a sensitive and specific non invasive diagnostic marker. Recently, S100A12 (Calgranulin C) have been established to be elevated in the feces of patients with IBD. The objective was to investigate the utility of fecal S100A12, in comparison to fecal Calprotectin and standard inflammatory markers, as a screening and distinguishing marker for IBD and Irritable Bowel Syndrome (IBS) in patients with chronic diarrhea. Stool samples were obtained from 173 individuals presenting with gastrointestinal symptoms requiring endoscopy. Fecal S100A12, fecal Calprotectin and serum S100A12 levels were measured and correlated to final diagnosis and standard tests (ESR, CRP, platelet count, albumin, perinuclear anti-neutrophil and antineutrophil cytoplasmic antibodies. Full colonoscopy with histopathological examination was performed. Patients diagnosed with IBD had elevated fecal S100A12 (median 49.7 mg kg-1) and Calprotectin (median 385 mg kg-1) levels compared with the patients without IBD (n = 35, S100A12: Median 4.6 mg kg-1, p<0.0001, Calprotectin: Median 30.5 mg kg-1; p<0.0001). Both the sensitivity and specificity of fecal S100A12 (cutoff 8 mg kg-1) for the detection of IBD were 93.91 and 97%, respectively whereas fecal Calprotectin (cutoff 35 mg kg-1) gave a sensitivity of 93.96% and a specificity of 84.2%. Both fecal markers were superior to the sensitivities and specificities of any standard inflammatory test. Both fecal S100A12 and Calprotectin are sensitive markers of gastrointestinal inflammation but fecal S100A12 provided exceptional specificity in distinguishing patients with IBD from patients without IBD.

  Background and Objective: As liver biopsy had multiple procedure-related complications, the introduction of reliable noninvasive tests for accurate discrimination of NASH and liver fibrosis in patients with NAFLD are mandatory. The aim was to elucidate the diagnostic value of fibrosis-4 index (FIB-4), Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) and Cytokeratin-18 fragments (CK18-Fs) in the prediction of NASH and liver fibrosis. Materials and Methods: One hundred Egyptian patients with NAFLD selected from outpatient's clinics of Mansoura University Hospitals underwent histological examination through liver biopsy after approval and consent. The FIB-4, HOMA-IR, CK18-Fs (measured using a human ELISA Kit) and their combination in FICK-3 score were investigated for predicting NASH and liver fibrosis. Receiver operating characteristic (ROC) curves and multivariate logistic regression were analyzed. Results: In patients with NAFLD, the areas under the ROC were significantly high (AUC: 0.765, 0.700, 0.803, 0.835 for FIB-4, HOMA-IR, CK18-Fs, FICK-3 score, respectively, p = 0.05) displaying a highly statistically significant predictive ability for NASH. Significantly higher AUCs for these parameters were demonstrated predicting early-or advanced-stage liver fibrosis (AUC >0.7, p<0.01). Also, the combined FICK-3 score (the sum of FIB-4 >1.46, HOMA-IR >2.11 and CK18-Fs >307U L1) had highly significant predictive values for NASH and liver fibrosis and had the best diagnostic accuracy at a cutoff value of 1(AUC >0.8, p<0.001). Contrasted with other diagnostic scores, FICK-3 had the best diagnostic accuracy for detection of fibrotic NASH (AUC = 0.954, p<0.001) and positively correlated with the histological features of NAFLD. Conclusion: The new combination FICK-3 score was a reliable and significant predictor for NASH and liver fibrosis in NAFLD Egyptian patients.
