Background

Posttransplantation anemia (PTA) is common in kidney transplant recipients, but comparative data guiding optimal pharmacotherapy are limited. This real world study provides the first head to head comparison of Pegmolesatide (a novel long acting ESA) versus Roxadustat (a HIF PHI) for PTA management.

Methods

In this single center retrospective cohort study, 63 consecutive PTA patients received either subcutaneous Pegmolesatide 4 mg once every four weeks (n=27) or oral Roxadustat 100-150mg thrice weekly with dose adjustment based on hemoglobin levels (n=36) according to physician discretion. Hb, serum creatinine, eGFR and iron parameters were measured at baseline and multiple follow up time points. Adverse events were recorded.

Results

Despite lower baseline Hb and eGFR in the Pegmolesatide group, Hb rose steadily in both cohorts. The primary outcome—percentage Hb change at three months—was significantly greater with Pegmolesatide (33.0±16.8% vs. 23.8±11.2%; P=0.014). This advantage was accentuated in patients with active infection (41.3±13.9% vs. 17.5±14.9%; P=0.006). Multivariable linear regression, adjusting for treatment assignment, age, BMI, baseline Hb, baseline eGFR, albumin, baseline proteinuria, transferrin, and infection status, confirmed treatment assignment as an independent predictor of hemoglobin response. Graft function remained stable in both groups and no treatment related adverse events were reported.

Conclusion

Pegmolesatide provided superior shortterm Hb correction over Roxadustat in PTA patients, especially in those with concomitant infection. These findings warrant validation in larger prospective trials.
