Abstract
The corona virus disease-2019 (COVID-19) pandemic has affected most of the world with varying degrees of morbidity and mortality. The presence of genetic polymorphisms may be associated with the severity and outcome of COVID-19 infection. This work aimed to evaluate the genetic polymorphisms of interleukin (IL-6) and IL-10 genes with the outcome of COVID-19 infection. This cross-sectional study was conducted on 354 patients who were classified into moderate and severe cases (including alive and deceased cases). All individuals were genotyped for one SNP for IL-6 (rs1800795) and one SNP for IL10 (rs1800896) using allelic discrimination real-time PCR technique. In this study, 198 cases were moderate, and 156 cases were severe. The risk of allele carriage of the minor allele of IL-6 rs1800795 (C) was significantly higher among the severe group when compared with that of the moderate group (p < 0.0001), while there was a mild significant difference of same allele carriage among alive cases when compared to that of deceased one (p < 0.04). Furthermore, the risk of the C allele of IL-10 rs1800896 was significantly increased in severe cases when compared with the moderate group (p < 0.0001), while there was no significant difference of the risk of the C allele in deceased cases when compared with that of alive ones (p > 0.05). In conclusion, the C allele (rs1800795) of IL-6 and the C allele (rs1800896) of IL-10 were highly significant in severe cases than in moderate cases. The C allele carriage of IL-6 showed only a significant difference between alive and deceased patients and not with the C allele of IL-10.

Abstract
Background: Hepatitis C virus (HCV) infection is a global public health burden. Chronic HCV infection leads to the development of fibrosis, cirrhosis, liver cancer, and liver failure over time.Methods: A total of 250 patients with chronic HCV infection and 299 healthy blood donors were recruited. Sixteen candidate single nucleotide polymorphisms (SNPs) in chemokine (C-C motif) ligand 2 (CCL2), CCL5, CCL8, C-C chemokine receptor 2 (CCR2), and CCR5 were genotyped in all participants.Results: The rs1024610 AA genotype was significantly associated with decreased susceptibility to chronic HCV infection. Aspartate aminotransferase (AST) levels, AST/platelet ratio index, and the fibrosis 4 score were significantly lower in the CCL2 rs1024610 T allele and haplotype ATGC carriers. Moreover, expression levels of collagen IV (C-IV) and laminin (LN) were significantly higher in patients with the CCL5 rs2280788 C allele compared to the non-carriers. Similarly, the expression levels of C-IV, LN, and hyaluronic acid were significantly higher in patients with the CCL5 haplotype, TGCT. No significant differences were identified between the SNPs/haplotypes and plasma levels of CCL2, CCL5, CCL8, CCR2, and CCR5 in the healthy controls, and the rs1024610 allele alteration had no effect on CCL2 promoter activity.Conclusions: This is the first study to report an association between CCL2 rs1024610 and the risk of chronic HCV infection in the Chinese Han population. rs1024610 and ATGC haplotype in CCL2 were reasonable candidate markers of liver abnormalities. rs2280788 and TGCT haplotype in CCL5 are likely to play a significant role in liver fibrosis during chronic HCV infection.

Abstract
Early microbial recognition by the innate immune system is accomplished by Toll-like receptors (TLRs), with resultant initiation of a pro-inflammatory response against infecting organisms. In spite of presence of an abundance of Toll-like receptors on the surface of the liver, gut bacteria does not elicit an inflammatory reaction in healthy individuals due to tolerance to these TLRs, suggesting that the inflammatory responses seen in the liver are the result of breakdown of this tolerance. While orthotopic liver transplantation is often life saving in many instances, death following this procedure is most commonly due to infection that occurs in up to 80% of transplant recipients, most commonly due to microbial causes in up to 70% of cases and viral infections in 20%, while fungal infections affect only 8% of cases. The probability of acquiring infection following hepatic transplantation is heightened due to affection of the innate immune defense mechanisms of the host following this procedure. Single nucleotide polymorphisms of TLRs have been associated with increased likelihood of either development of post-transplant infection or eradication of infecting organism. However, conflicting reports from other studies reveal that prevalence of this single nucleotide polymorphism is not increased in infected patients.

Abstract
In 2019 the British Journal of Biomedical Science published 40 articles in the various disciplines that comprise biomedical science. These were one review, 22 original articles and 17 'In Brief' short reports. Of those citing original data, the majority were in cellular pathology (14 papers), clinical chemistry (9 papers), and microbiology (6 papers: 4 in bacteriology and 2 in virology). There were 3 papers in haematology and 2 in andrology, whilst 5 papers crossed traditional discipline boundaries (such as the molecular genetics of IL6, liver function tests, and hepatocellular carcinoma). Over two-thirds of papers used techniques in molecular genetics. The present report will summarise key aspects of these publications that are of greatest relevance to laboratory scientists.

Abstract
Background: HCV infection is related to aberrant methylation of several genes. RASSF1A, E-Cadherin and RUNX3 are tumour suppressor genes that may be inactivated by hypermethylation in many tumours including hepatocellular carcinoma (HCC). We hypothesized that methylation is a diagnostic biomarker for HCC in patients with HCV-related liver cirrhosis.Methods: We recruited 207 cases of HCV-related liver cirrhosis, 193 HCC patients and 53 healthy controls. Methylation-specific polymerase chain reaction for detection of circulating hypermethylated RASSF1A, E-Cadherinand RUNX3. Alpha fetoprotein (AFP) was measured by commercial immunoassay.Results: Significant hypermethylation of the three genes was found in the HCC group compared to both cirrhosis and healthy groups (P < 0.001), whereas no significant difference in hypermethylation was found between cirrhosis and healthy groups (P = 0.17, 0.50 and 0.14, respectively). No significant links were found between hypermethylated RASSF1A, E-Cadherin and RUNX3 and stages of Barcelona Clinic of Liver Cancer score (P =0.21, 0.63 and 0.98, respectively). No significant associations were found between AFP value and hypermethylated genes in cirrhosis and HCC groups (P = 0.82) except with E-Cadherin in HCC (P = 0.02). In multiple regression analysis, RASSF1A and E-Cadherin were predictors of HCC within cirrhosis cases, but only E-Cadherin was an independent risk factor for prediction of HCC in cases with low AFP (P = 0.01).Conclusions: The presence of hypermethylated serum RASSF1A, E-Cadherin and RUNX3 is linked to HCC in patients with HCV-related cirrhosis. Only E-Cadherin is an independent risk factor for prediction of HCC with low AFP. These findings may be of diagnostic value.

Abstract
Background: As hepatocellular carcinoma (HCC) arising from chronic hepatitis C virus (HCV) infection in liver cirrhosis is a major problem in public health, early and rapid prediction of HCC is urgent. We hypothesized that a single nucleotide polymorphism in the Apa1 SNP in the vitamin D receptor may help diagnosis.Methods: We recruited 3 groups: 80 HCC patients with HCV cirrhosis, 80 HCV cirrhotic patients free of HCC and 80 healthy controls. Apa1 rs7975232 SNP was detected by PCR- RFLP technique. Routine laboratory markers were determined by standard methods.Results: The Apa1 CC genotype was more frequent (75%) in HCC than in the cirrhosis (35%) and control (20%) groups (P<0.0001). CC patients were more likely to have a more severe Child-Pugh score (P=0.027) and MELD score (P<0.05). In multivariate analysis, the CC genotype out-performed AFP is determining HCC.Conclusion: Apa1 CC genotype is linked to HCC in HCV C cirrhotic patients, and so has the potential to be an independent biomarker predictor for HCC occurrence in HCV cirrhosis.

Abstract
Background and Aims: Genetic polymorphisms of Toll-like receptors (TLRs) have been proposed to affect susceptibility to HCV infection and progression to end-stage liver disease. This study was conducted to clarify the association of SNPS of TLR2 and TLR4 with clinical outcome of hepatitis C, response to treatment and development of HCC.Methods: The current study examined 3295 individuals from 725 families that were categorized into groups comprising chronic HCV (CH), spontaneous viral clearance (SC) and control subjects. Treated patients were classified into responders (RT) and non-responders (NRT). In addition, patients with liver cirrhotic (LC), and hepatocellular carcinoma (HCC) were also included. All subjects were genotyped for five single nucleotide polymorphisms (SNPs) of TLR2 and four SNPs of TLR4 and their haplotypes using allelic discrimination real-time PCR.Results: Results demonstrated strong association with allele A of rs13105517 of TLR2 and allele C of rs10116253 of TLR4 with CH in comparison to SC group. However, The peak of risk of HCC was observed with allele C of rs3804099 of TLR2 and C allele of rs10116253 TLR4 (p < 0.001).A strong association was found with allele T of rs1816702 of TLR2 and allele A of rs5030728 of TLR4 in non responder group in comparison to responders (p < 0.001). Haplotypes CAGT of TLR4 and ATAC of TLR2 showed significant association with CH and HCC groups in comparison to other groups.Conclusions: This study shows an association of minor alleles of TLR2 and TLR4 with outcome of HCV infection, response to therapy and development of HCC in cirrhotic patients.

Abstract
BACKGROUND Hepatitis C virus (HCV) related liver cirrhosis occurs in about 20% of chronically infected patients over a duration of 10-20 years, and within 5 years approximately 10-20% of these cirrhotic patients will develop hepatocellular carcinoma (HCC). Previous studies report that the X-ray repair cross-complementing group1 gene (XRCC1) is important in the risk of HCC development; however, results obtained from these studies are conflicting rather than conclusive. We hypothesised an association between single nucleotide polymorphisms (SNPs) in XRCC1 with the HCC risk on a background of chronic hepatitis C. MATERIALS AND METHODS We recruited 210 subjects, 70 with HCC, 70 with cirrhosis and 70 healthy controls. Two SNPs [c.1254C>T(rs2293035) and c.1517G>C(rs139599857)] in XRCC1 were genotyped using created restriction site-polymerase chain reaction (CRS-PCR) and PCR-restriction fragment length polymorphism (PCR-RFLP) methods. RESULTS The TT genotype, CT genotype and T-allele in c.1254C>T (rs2293035) were linked to risk of HCC compared to the CC genotype: OR 3.58 [confidence interval (CI) 95%: 1.19-10.7] p = 0.019; OR 2.16 (CI 95%: 1.04-4.47) p = 0.037 and OR 2.10 (CI 95%: 1.2-3.3) p = 0.006, respectively. Regarding c.1517G>C (rs139599857), the CC genotype, GC genotype and C-allele were linked with higher risk of developing HCC compared to GG genotype: OR 4.77 (CI 95%: 1.3-16.9), p = 0.016; OR 3.02 (CI 95%: 1.46-6.2), p = 0.002 and OR 2.4 (CI 95%: 1.4-4.0), p = 0.001, respectively. CONCLUSION We conclude that the T-allele of c.1254C>T (rs2293035) and the C allele of c.1517G>C (rs139599857) genetic variants may be associated with increased HCC risk among chronic hepatitis C patients.
