# Risk for Donor-Derived Syphilis after Kidney Transplantation, China, 2007–2022

## TL;DR

This study examines the risk of syphilis transmission through kidney transplants in China from 2007 to 2022.

## Contribution

The study identifies factors influencing donor-derived syphilis risk and suggests ceftriaxone may reduce transmission.

## Key findings

- Donor-derived syphilis was rare among kidney transplant recipients.
- Active syphilis in donors may increase transmission risk.
- Recipient treatment with ceftriaxone could reduce the risk.

## Abstract

To evaluate the risk of acquiring syphilis from a donated kidney, we evaluated kidney transplantation pairs from West China Hospital, Sichuan, China, during 2007–2022. Donor-derived syphilis was rare. Risk may be higher if donors have active syphilis and may be reduced if recipients receive ceftriaxone.
