Summary
Hepatitis C virus (HCV) infection is common in kidney disease patients, causing kidney damage. While HCV-positive kidney transplant recipients show better survival than dialysis patients, allograft survival is reduced due to disease recurrence.
Area of Science:
- Nephrology
- Hepatology
- Infectious Diseases
Background:
- Hepatitis C virus (HCV) is a frequent complication in patients with kidney disease, often leading to glomerular diseases and end-stage renal disease (ESRD).
- Regular monitoring for proteinuria, hematuria, and estimated glomerular filtration rate is recommended for HCV-infected patients.
- Membranoproliferative glomerulonephritis is the most prevalent glomerular disease associated with HCV infection.
Purpose of the Study:
- To review the impact of Hepatitis C virus infection on kidney disease progression and patient outcomes.
- To evaluate the role of kidney transplantation in HCV-positive dialysis patients.
- To assess the effect of dialysis and transplantation on liver fibrosis progression and occult HCV infection.
Main Methods:
- Review of existing literature on Hepatitis C virus infection in kidney disease, dialysis, and kidney transplantation.
- Analysis of patient survival data comparing HCV-positive and HCV-negative individuals in dialysis and transplant settings.
- Examination of factors influencing kidney allograft survival in HCV-positive recipients.
Main Results:
- HCV infection can cause glomerular disease, potentially leading to ESRD requiring dialysis or transplantation.
- Survival rates are lower for HCV-positive dialysis patients compared to HCV-negative counterparts.
- HCV-positive kidney transplant recipients demonstrate better survival than HCV-positive dialysis patients, but lower allograft survival than HCV-negative recipients due to disease recurrence or de novo occurrence.
Conclusions:
- Kidney transplantation should be considered for dialysis patients with HCV infection who do not achieve sustained virological response.
- While transplantation improves survival compared to dialysis for HCV patients, strategies to mitigate kidney allograft disease recurrence are needed.
- Occult HCV infection is unlikely in dialysis and kidney transplant patients, and dialysis/transplantation do not significantly worsen liver fibrosis.

01:25Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
01:24Chronic Kidney Disease II: Clinical Manifestations
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...
01:28Kidney Transplant I: Introduction
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
01:26Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow
Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug binding...
