Background

End stage renal disease (ESRD) patients (pts) are at increased risk of infections due to immune dysregulation, malnutrition, and indwelling dialysis access. After transplant (tx), pts are at further risk due to immunosuppressive therapy. Characterization of infections in large, real world samples will allow clinicians to better evaluate and understand infection risks in their patients. The objective of this study was to characterize the rates of serious and opportunistic infections in ESRD and renal tx pts.

Methods

We conducted a retrospective cohort study using the Truven Healthcare MarketScan^® Commercial Claims and Encounters and Medicare Supplemental and Coordination of Benefits database between 2000 and 2014. The ESRD cohort index date was the first of either an ESRD or dialysis claim, separated by ≥7 days. The tx cohort index date was the first of ≥2 claims related to kidney tx, separated by ≥7 days.

Results

23,433 ESRD pts on dialysis and 18,660 renal tx pts were identified. One year following the index date, the rates of serious infections were higher in ESRD than tx pts. Most serious infections required hospitalization in both groups and opportunistic infection rates were comparable (Table 1).

Conclusion

ESRD and post-tx pts experience serious infections with high rates of hospitalization indicating high burden of illness. Physicians should carefully evaluate infection risks when considering pre- and post-tx immunosuppressive regimens.
