Given the success of direct-acting antivirals (DAAs) in treating hepatitis C (HCV), interest is growing in utilizing solid organs from allografts with active HCV to expand donor availability.
To review post-transplant outcomes and patient survival in HCV-negative recipients receiving solid organ transplants (SOT) from viraemic, that is, HCV+/NAT+ (nucleic acid testing) allografts.
A literature search was conducted on PubMed and EMBASE from 01/01/2007 to 4/17/2021 for articles matching eligibility criteria. Two authors independently screened titles and abstracts. Disagreements were solved by a third independent reviewer. Methodological quality assessment was done using a modified Newcastle-Ottawa scale (NOS). Data synthesis was done qualitatively using median, ranges and percentages.
Thirty-five studies were included (or 852 SOTs): 343 kidney, 233 heart, 204 liver, and 72 lung transplants from viraemic allografts. Of the recipients eligible for sustained virological response at 12 weeks (SVR12) calculation, 100% achieved cure from HCV. No deaths/graft failures were reported to be related to HCV transmission. Seven SOT recipients had viral relapse, with all seven patients treated successfully. Four patients developed fibrosing cholestatic hepatitis with complete resolution post-treatment.
Transplanting viraemic organs into uninfected individuals can become the standard of care for patients who do not have contraindications to DAAs.
