ABSTRACT
Mycoplasma hominis and Ureaplasma species are urogenital mollicutes that can cause serious donor-derived infections in lung transplant recipients. Best practices for mollicute screening remain unknown. We conducted a single center prospective study analyzing lung transplants performed from 10/5/20 - 9/5/21 whereby donor and recipient bronchoalveolar lavage (BAL) samples obtained at time of transplant underwent mollicute screening via culture and polymerase chain reaction (PCR). Of 115 total lung transplants performed, 99 (86%) donors underwent combined mollicute BAL culture and PCR testing. The study cohort included these 99 donors and their matched recipients. In total, 18 (18%) of 99 donors screened positive via culture or PCR. Among recipients, 92 (93%) of 99 had perioperative BAL screening performed, and only 3 (3%) had positive results. After transplant, 9 (9%) recipients developed mollicute infection. Sensitivity of donor screening in predicting recipient mollicute infection was 67% (6/9) via culture and 56% (5/9) via PCR. Positive predictive value (PPV) for donor culture was 75% (6/8), compared to 33% (5/15) for PCR. Donor screening via culture predicted all serious recipient mollicute infections and had better PPV than PCR; however, neither screening test predicted all mollicute infections. Independent of screening results, clinicians should remain suspicious for post-transplant mollicute infection.
