Hepatitis C virus infection and global kidney health: the consensus proceedings of the International Federation of Kidney Foundations
Hepatitis C virus (HCV) infection is an important cause of major morbidities including chronic liver disease, liver cancer, acute kidney injury and chronic kidney disease (CKD). Among patients with kidney disease who have HCV infection, the clinical outcomes are worse. The prevalence of HCV infection is exceptionally high among dialysis and kidney transplant patients throughout the globe. It is estimated that 5% to 25% or more of dialysis-dependent patients are affected. Almost half of all deaths in CKD patients, including HCV-infected patients, are due to cardiovascular disease, and HCV-infected patients have higher mortality. Given the importance and impact of the HCV epidemic on global kidney health, and the status of Egypt as the nation with the highest prevalence of HCV infection in the world along with its initiatives to eradicate HCV, the International Federation of Kidney Foundations convened a consensus conference in Cairo in December 2017. This article reflects the opinions and recommendations of the contributing experts and reiterates that, with the current availability of highly effective and well tolerated pharmacotherapy, CKD patients should be given priority for the treatment of HCV, as an important step towards the World Health Organization’s goal of eliminating viral hepatitis as a public health problem by 2030

Sa1057 The Impact of Normal Liver Transaminases on Hepatic Fibrosis and Response to HCV Treatment: A Cohort Egyptian Study of 4277 Patients
Human Leukocyte Antigen Class II Alleles (DQB1 and DRB1) as Predictors for Response to Interferon Therapy in HCV Genotype 4
Human leukocyte antigens class II play an important role in immune response against HCV. We investigated whether HLA class II alleles influence susceptibility to HCV infection and response to interferon therapy. HLA-DRB1 and -DQB1 loci were genotyped using PCR-SSO Luminex technology. According to our regimen, 41 (66%) of patients achieved sustained virological response to combined treatment of IFN and ribavirin. Frequencies of DQB1*0313 allele and DRB1*04-DRB1*11, DQB1*0204-DQB1*0313, DQB1*0309-DQB1*0313, and DQB1*0313-DQB1*0319 haplotypes were significantly more frequent in nonresponders than in responders. In contrast, DQB1*02, DQB1*06, DRB1*13, and DRB1*15 alleles were significantly more frequent in responders than in nonresponders. Similarly, DRB1*1301, DRB1*1361, and DRB1*1369 alleles and DRB1*1301-DRB1*1328, DRB1*1301-DRB1*1361, DRB1*1301-DRB1*1369, DRB1*1328-DRB1*1361, and DRB1*1328-DRB1*1369 haplotypes were significantly found only in responders. Some alleles and linkages showed significantly different distributions between patient and healthy groups. These alleles may be used as predictors for response to treatment or to susceptibility to HCV infection in the Egyptian population
Diffusion-weighted MRI and fibroscan vs. histopathology for assessment of liver fibrosis in chronic HCV patients: (Pilot study)
Introduction: HCV infection is responsible for liver fibrosis. Fibroscan and diffusion MRI have been proposed for non-invasive diagnosis and staging of hepatic fibrosis.
Aim of the work: To assess the accuracy of diffusion MRI and/or fibroscan in the diagnosis of liver fibrosis as compared to histopathology. Patients and methods pre-treatment laboratory work up, fibroscan, diffusion MRI of the liver and liver biopsy were done for 52 chronic HCV patients for assessment of liver fibrosis.
Results: There was a significant difference between ADC values of F0 vs. F1, F3 and F4 (P = 0.008, 0.033 and 0.015) respectively, however no significant differences were seen in the ADC values between the other different fibrosis stages. As regard the liver stiffness values, there was a significant difference between F1 and F3 (P = 0.001), F1 and F4 (P = 0.024) and between F2 and F3 (P = 0.014).There was no significant difference in the ADC values between (F0, F1, F2) on one hand and (F3, F4) on the other hand (P = 0.387), while there was a highly significant difference in the liver stiffness values between both groups (p < 0.001).
Conclusions: Diffusion MRI can distinguish non-fibrotic liver (F0) from advanced fibrosis (F3 and F4) but cannot be used to distinguish between the intermediate stages of fibrosis-fibroscan can differentiate between (F0, F1, F2) and (F3, F4)
Association Analysis of Genetic Variants of Sodium Taurocholate Co-Transporting Polypeptide NTCP Gene \u3cem\u3e(SLC10A1)\u3c/em\u3e and HBV Infection Status in a Cohort of Egyptian Patients
Background: Single nucleotide polymorphisms (SNPs) in the SLC10A1 gene, coding for a functional receptor of hepatitis B virus (HBV), sodium taurocholate co-transporting polypeptide (NTCP), may influence the susceptibility, outcome, and disease course of HBV infection in some populations. Aim: to determine the prevalence of SNPs of the NTCP gene, rs2296651 and rs943277, and their relationship with chronic HBV infection in a group of Egyptian patients. Methods: One hundred and thirty seven patients with HBV and 65 healthy controls were enrolled, and the patients were divided into two groups; group I chronic HBV infection (68 patients with normal ALT and minimal or no liver necroinflammation or fibrosis) and group II chronic hepatitis B (69 patients with elevated ALT and moderate or severe liver necroinflammation). They were subjected to full history taking, clinical examination, laboratory investigations, abdominal ultrasound, and liver stiffness measurement using both Echosens® Fibroscan and acoustic radiation force impulse (ARFI). A real time PCR TaqMan 5′ allelic discrimination assay was applied to detect the SNPs in the NTCP gene, rs2296651 and rs943277. Results: On studying the rs2296651 variant, all controls and patients had genotype GG without any significant association with HBV infection or disease progression. However, the rs943277 variant in all controls and 98% of patients had genotype GA, except for two chronic HBV infection patients who had genotype AA, but no significant difference between patients and controls was found. The non-invasive methods for liver fibrosis assessment ARFI, AST/platelet’s ratio (APRI), and fibrosis-4 score (FIB-4) could predict the stages of fibrosis in agreement with Fibroscan with AUCOR 0.8, 0.79, and 0.76, respectively. Conclusion: These findings may suggest that there is no relation between these SNPs of the NTCP gene and the susceptibility or chronicity of HBV infection in the Egyptian population. We also suggest that the use of the non-invasive methods for liver fibrosis assessment, ARFI, FIB-4, and APRI, may decrease the need for liver biopsies in the prediction of significant hepatic fibrosis in chronic HBV patients
IP-10 Serum Level in Chronic Hepatitis C Virus Patients: Relation to Fibrosis and Response to Combined Interferon/Ribavirin Therapy
Hepatitis C virus infection and global kidney health: the consensus proceedings of the International Federation of Kidney Foundations.
Hepatitis C virus (HCV) infection is an important cause of major morbidities including chronic liver disease, liver cancer, and acute kidney injury (AKI) as well as chronic kidney disease (CKD). HCV can affect kidney health; among CKD and AKI patients with HCV infection, the clinical outcomes are worse. The prevalence of HCV infection is exceptionally high among dialysis and kidney transplant patients throughout the globe. It is estimated that 5% to 25% or more of dialysis dependent patients are affected by chronic HCV, based on the region of the world. Almost half of all deaths in CKD patients, including HCV-infected patients, are due to cardiovascular disease, and HCV infected patients have higher mortality. Given the importance and impact of the HCV epidemic on CKD and global kidney health, and the status of Egypt as the nation with highest prevalence of HCV infection in the world along with its leading initiatives to eradicate HCV, the International Federation of Kidney Foundations (IFKF) convened a consensus conference in Cairo in December 2017. This article reflects the opinions and recommendations of the contributing experts and reiterates that with the current availability of highly effective and well tolerated pharmacotherapy; CKD patients should be given priority for treatment of HCV, as an important step towards the elimination of viral hepatitis as a public health problem by 2030 according to World Health Organization and IFKF. Every country should have an action plan with the goal to improve kidney health and CKD patient outcomes
