RESUMO
Angiotensin-converting enzyme inhibitors (ACEi) are frequently used antihypertensive medications with additional advantages such as reducing proteinuria and cardiovascular events. ACEi are commonly held at least 24 hours before a therapeutic plasma exchange (TPE) to reduce possibility of adverse events (AEs) including adverse drug reactions (ADR). The objective of this study was to determine if ACEi use increases the risk of ADR in patients receiving TPE with a conventional centrifuge-based apheresis system. This is a retrospective chart review study (n = 252; 52% male). Binary logistic regression was used to analyze the association of ACEi use and AEs. Of 171 patients who had AE during TPE, only 38 patients were taking ACEi. There was no significant association between ACEi use and AEs after adjustments (odds ratio = 0.885, 95% confidence interval: 0.468, 1.674). Our results suggest that risk of AEs is not higher in patients taking ACEi receiving TPE using a centrifuge-based machine. Randomized controlled prospective trials may be needed to further investigate this matter.
