Hepatitis C virus and kidney: a strong association with different clinical aspects

Area of Science:

• Nephrology
• Hepatology
• Immunology

Background:

• Chronic hepatitis C virus (HCV) infection is linked to significant kidney disease, primarily membranoproliferative glomerulonephritis in patients with type II mixed cryoglobulinaemia.
• Clinical signs of glomerular disease in HCV patients include proteinuria and haematuria, potentially with reduced kidney function.
• The pathogenesis of HCV-mediated renal dysfunction, often involving cryoglobulins, is not fully understood, leading to varied pharmaceutical approaches.

Purpose of the Study:

• To review the primary renal manifestations of HCV infection.
• To describe the epidemiological and clinical features of HCV-related chronic kidney disease (CKD).
• To evaluate current therapeutic regimens for HCV-associated kidney disease, highlighting limitations.

Main Methods:

• Literature review of studies on HCV infection and kidney disease.
• Analysis of epidemiological and clinical data for CKD patients with HCV.
• Critical assessment of current treatment strategies and their efficacy.

Main Results:

• HCV infection adversely affects survival in patients on renal replacement therapy.
• Established safe and effective pharmaceutical regimens for HCV-related kidney disease are lacking.
• The use of anti-HCV-positive donor kidneys for transplantation is debated due to survival benefits versus concerns.

Conclusions:

• Current therapeutic regimens for HCV-associated kidney disease are limited and require improvement.
• Further research is needed to elucidate the pathogenesis and develop effective treatments.
• Management strategies for HCV in renal patients, including transplantation considerations, need careful evaluation.
