This research aims to evaluate the prevalence and predictors of Occult HCV among hemodialysis (HD) patients who achieved 24 weeks sustained virological response (SVR) after treatment with direct-acting antiviral agents (DAA) by detection of viral RNA in their peripheral blood mononuclear cells.
In maintenance hemodialysis (MHD) patients, hepatitis C virus (HCV) infection is common and may be associated with poor clinical outcomes. A lot of treatment options for HCV have rapidly evolved over the past 5 years and various treatment choices for patients with advanced CKD are currently available.1 The reappearance of HCV infection months or years after sustained virologic response (SVR) may be due to the persistence of HCV in tissue cells in spite of being undetected in serum. This situation is known as occult hepatitis C infection (OCI).2 OCI is now a challenging entity in the field of post hepatitis management and follow-up. OCI is described when HCV-RNA is detectable in liver and/or peripheral blood mononuclear cells (PBMCs) in patients with undetectable serum HCV-RNA. To our knowledge , this is the first research to issue this problem in dialysis patients after treatment with direct acting antiviral drugs.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| participants | Experimental | Immediately after confirmation of 24 weeks SVR after the end of treatment, we will collect samples of peripheral blood from each patient into EDTA tube and test for HCV RNA in peripheral blood mononuclear cells (PBMCs) . All patients included in this study will be subjected to full history taking and thorough clinical examination. The initial pre treatment data of the patients will be revised including body mass index (BMI), pre treatment status (naïve,experienced), pretreatment viral load by sensitive real-time HCV PCR technique, liver function tests, complete blood count, prothrombin time, international normalized ratio , Child-Pugh score, MELD score and FIB-4 score . |

This research is a cross sectional study. Target population: thirty patients with end-stage renal disease (ESRD) receiving hemodialysis treatment from different dialysis centers in Alexandria will be enrolled in the study after achieving sustained virological response 24 weeks after the end of treatment with directly acting antiviral drugs (DAADs).will be screened for the presence of occult HCV infection.
