Genotype and Superinfection
Hepatitis C in Renal Disease, Hemodialysis and TransplantationThis flow traces the attempt to reduce transplant-related viral danger by matching donor and recipient genotypes.

No Protective Immunity
Reinfection remains possible
Prior HCV infection does not guarantee protection against another strain. A recipient may acquire a second genotype even while already carrying one viral population.
Clinical uncertainty
Mixed infection complicates virology and may increase the unpredictability of liver disease. The transplanted kidney therefore creates a new exposure even within an already infected body.
Mismatch Crisis

Mismatch Crisis
A severe example
Reports of severe hepatitis after genotype mismatch turn a theoretical concern into a clinical warning. The recipient’s prior infection does not neutralize the incoming strain.
Limits of timing
Genotype matching could reduce danger, but organ allocation operates under time pressure. Virologic precision must compete with the urgency of transplantation.
Matching as Ideal

Matching as Ideal
A safer allocation principle
Whenever logistics permit, matching donor and recipient genotypes may reduce superinfection risk. The principle represents an effort to convert biological knowledge into allocation policy.
An incomplete solution
Matching cannot remove all transmission risk, and rapid organ decisions may make it impossible. It remains a preferred refinement rather than a universal requirement.
