Abstract

Background : Proton pump inhibitors (PPIs) are often prescribed after kidney transplantation to prevent gastrointestinal complications despite the lack of evidence. There are conflicting opinions reporting on an association between PPI prophylaxis and acute rejection. Additionally, several studies have reported increased risk of infections and hematological events of PPI use. The purpose of this study was to investigate risks of PPI prophylaxis early after kidney transplantation.
Methods : We retrospectively analyzed the records of patients who received kidney transplantations September 2016-February 2018 using standard immunosuppressive regimens. The endpoints were to compare the incidence of adverse events, biopsy-proven acute rejection (BPAR), and graft failure within three months and six months after transplantation.
Results : A total of 190 recipients were included in this study; of which 56 were included in the PPI group and 134 were included in the no-PPI group. Seven (12.5%) patients in the PPI group and five (3.7%) patients in the no-PPI group developed BPAR within three months, which was statistically significant (p=0.044). There was no significant difference in BPAR within six months (7[12.5%] vs. 9[6.7%], p=0.250, respectively). One patient taking PPI was diagnosed with graft failure. Infectious adverse events were not significantly different between the groups. Grade Ⅱ thrombocytopenia was more common in the PPI group (5[8.9%] vs. 2[1.5%], p=0.024, respectively).
Conclusion : PPI prophylaxis after kidney transplantation was associated with acute rejection and severe thrombocytopenia. Further studies are needed to investigate the association between PPI and other complications.
