Liver disease progression from chronic hepatitis C virus (HCV) infection to hepatocellular carcinoma (HCC) is associated with an imbalance between T-helper 1 and T-helper 2 cytokines. Evaluation of cytokines as possible candidate biomarkers for prediction of HCC was performed using soluble Fas (sFas), soluble tumor necrosis factor receptor-II (sTNFR-II), interleukin-2 receptor (IL-2R) and interleukin-8 (IL-8).

Combined pegylated interferon-α and ribavirin therapy has sustained virological response (SVR) rates of 54% to 61%. Pretreatment predictors of SVR to interferon therapy have not been fully investigated yet. The current study assesses a group of chemokines that may predict treatment response in Egyptian patients with chronic HCV infection. CXCL5, CXCL9, CXCL11, CXCL12, CXCL 13, CXCL 16 chemokines and E-Cadherin were assayed in 57 chronic HCV patients’ sera using quantitative ELISA plate method. All studied patients were scheduled for combined pegylated interferon alpha and ribavirin therapy (32 patients received pegylated interferon α 2b, and 25 patients received pegylated interferon α 2a). Quantitative hepatitis C virus RNA was done by real time RT-PCR and HCV genotyping by INNOLIPAII. There was no significant difference (p > 0.05) in baseline HCV RNA levels between responders and non-responders to interferon. A statistically significant difference in CXCL13 (p = 0.017) and E-Cadherin levels (P = 0.041) was reported between responders and nonresponders at week 12. Significant correlations were found between changes in the CXCL13 levels and CXCL9, CXCL16, E-cadherin levels as well as between changes in E-cadherin levels and both CXCL16 and ALT levels that were maintained during follow up. Also, significant changes have been found in the serum levels of CXCL5, CXCL13, and CXCL16 with time (before pegylated interferon α 2 a and α 2 b therapy, and at weeks 12 and 24) with no significant difference in relation to interferon type and response to treatment. Serum levels of CXCL13 and E-Cadherin could be used as surrogate markers to predict response of combined PEG IFN-α/RBV therapy, especially at week 12. However, an extended study including larger number of patients is needed for validation of these findings. NCT01758939

Background: Solid organ transplantation (SOT) service has been disrupted during the current coronavirus disease 2019 (COVID-19) pandemic, which deferred the service in most centers worldwide. As the pandemic persists, there will be an urgency to identify the best and safest practices for resuming activities as areas re-open. Resuming activity is a difficult issue, in particular, the decision of reopening after a period of slowing down or complete cessation of activities. Objectives: To share our experience in resuming living donor liver transplantation (LDLT) in the context of the COVID-19 pandemic in the Liver Transplantation Unit of El-Manial Specialized Hospital, Cairo University, Egypt, and to review the obstacles that we have faced. Material and methods: This study is a single-center study. We resumed LDLT by the 26th of August 2020 after a period of closure from the 1st of March 2020. We have taken a lot of steps in order to prevent COVID-19 transmission among transplant patients and healthcare workers (HCWs). Results: In our study, we reported three LDLT recipients, once resuming the transplantation till now. All our recipients and donors tested negative for SARS-CoV-2 by nasopharyngeal RT-PCR a day before the transplantation. Unfortunately, one of them developed COVID-19 infection. We managed rapidly to isolate him in a single room, restricting one team of HCWs to deal with him with strict personal protective measures. Finally, the patient improved and was discharged in a good condition. The second patient ran a smooth course apart from FK neurotoxicity which improved with proper management. The third patient experienced a sharp rise in bilirubin and transaminases on day 14 that was attributed to drug toxicity vs. rejection and managed by discontinuing the offending drugs and pulse steroids. In addition, one of our head nurses tested positive for SARS-CoV-2 that was manageable with self-isolation. Conclusion: Careful patient, donor, personnel screening is mandatory. Adequate supply of personal protective equipments, effective infection control policies, and appropriate administrative modifications are needed for a safe return of LDLT practice.
