In this study, as part of the larger HIV Organ Policy Equity pilot study, HIV-positive to HIV-positive kidney and liver transplant recipients in the USA were examined for evidence of sustained donor-derived HIV superinfection. In this multicentre, prospective, observational study, HIV-positive to HIV-positive kidney and liver transplant recipients were followed in three hospitals in the USA. Candidates with well controlled HIV infection on ART, no active opportunistic infections, and minimum CD4 T-cell counts (>100 cells per μL for liver and >200 cells per μL for kidney per federal guidelines) were eligible to receive a kidney or liver from deceased HIV-positive donors without active infections or neoplasm. Peripheral blood mononuclear cells were collecte superinfection. One recipient had a viraemic episode (viral load of 2 080 000 copies per mL) 3 years after transplantation as a result of non-adherence to ART. Only recipient viral sequences were detected during the viraemic episode, suggesting that the donor virus, if present, was not reactivated despite temporary withdrawal of ART. These findings suggest that loss of HIV suppression due to donor-derived HIV superinfection might not be a significant clinical concern in carefully monitored ART suppressed HIV-positive organ recipients.

However, in cystic fibrosis, stimulating submucosal glands has the oppo
