Adverse events were reported in 5.88% of patients, including hypotension, vasovagal reflex, and one case of facial edema and urticaria. No procedure-related deaths were observed. TPE sessions were conducted in accordance with the guidelines of the ASFA, with 50% of procedures classified as Category I.

In this single-center, retrospective study, patients with pulmonary transplant AMR who received a TPE-containing treatment regimen were examined. Mean fluorescence intensity (MFI) and Class distribution of DSAs were examined before/after 5 TPE and again after 8 TPE in the subset of patients who received an extended course of TPE. Fifty-two patients who completed 5 TPE were included. Testing of serum at 1:1 and 1:16 prior to initiation of TPE demonstrated that Class II DSAs occurred more frequently and at a higher MFI compared to Class I DSAs. After completing 5 TPE, for both 1:1 and 1:16 testing, the MFI of DSAs decreased significantly regardless of Class. For 4 patients with persistent DSAs, extending the course of TPE to 8 procedures did not cause an additional significant decline in the MFI of DSAs. Four patients developed de novo DSAs during the course of 5 TPE. Development of de novo DSAs was not associated with plasma exposure during TPE and was associated with high morbidity. In conclusion, completion of 5 TPE during treatment for pulmonary transplant AMR is associated with significant declines in DSAs regardless of HLA Class. Extending the course of TPE for DSAs which persist despite 5 TPE may be of limited benefit.
