Transplant Transmitted Infections

Ensuring the gift of life is safely delivered

For certain health conditions, transplantation of solid organs, tissues, or cells from a donor to a recipient is often the only cure.

End-stage organ failure is estimated to affect more than six million people worldwide.1 Advancements in surgical techniques, immunosuppression, donor–recipient matching, and antimicrobial agents have all contributed to increase patient success during transplant procedures.2 

However, complications due to infection after transplantation are one of the main causes of post-operative morbidity and mortality— including rejection or loss of the graft or the transplant, among other challenges.3

Donor-derived infections highlight the need for pre-transplant screening

Due to high demand for organs and cells, every potential donor should be considered. However, this can open the possibility of transmitting infections and to a lesser extent malignancy, from the donor organ to the immunosuppressed recipient, possibly affecting long-term organ function.4

Addressing this requires an appropriate assessment of the potential risks of infections pre-transplantation (including the use of donations testing positive for treatable infections) to ensure a successful graft.

Opportunistic infection can cause post-transplant complications if not managed

Immunosuppressive regimes are critical in controlling organ rejection but can increase the susceptibility of patients to certain infections.5 Cytomegalovirus (CMV) is one of the major sources of transplant-transmitted infections, affecting about 60-100% of adults after transplantation.6 Other notable pathogens include BK virus (BKV), Epstein-Barr virus (EBV), Herpes Simplex Virus (HSV), Varicella Zoster Virus (VZV), Toxoplasma gondii (Toxo), human Adenovirus (hADV) and, more recently, SARS-CoV-2.7-9

Pre- and post-transplantation laboratory testing is critical to making the most out of every donation and to ensuring patients get the life-saving surgeries they need.

Clinical laboratorians play a key role in the success of transplant programs

Minimizing risk requires comprehensive and reliable pre- and post-transplant testing.

From initial screening to post-transplantation follow-up, several samples are needed to run multiple tests for possible pathogens. Across serologic and molecular testing, increased automation, broad testing menus, and streamlined workflows are enabling laboratories to more efficiently process samples and identify potentially problematic pathogens.
