Dialysis patients are often iron deficient due to a multiple factors. Ferric pyrophosphate citrate is a complex iron salt that can be given via dialysate allowing maintenance of hemoglobin (Hgb) concentration and iron balance while reducing the need for IV iron. The purpose of this study is to perform a cost evaluation of FPC and the effect it has on lowering the dose/use of ESAs and IV iron therapy. This study reviewed the same 100 hemodialysis patient's charts before and after the use of FPC. The data points that were collected and analyzed are as follows: hemoglobin, ferritin levels, average weekly ESA dosing, and IV iron replacement therapy dose. Out of 100 patients, there was no statistical difference in the average hemoglobin, ferritin, and iron saturation levels observed in the patients before and after FPC use. The average weekly dose of darbepoetin alfa per patient was 52.74 μg before the FPC group compared to 39.27 μg in the post FPC group (P < .0001). The total dose of ferric gluconate per patient was 3290.01 mg in the before FPC group and 585.60 mg in the post FPC group (P < .0001). The average total iron sucrose dose per patient in the before FPC group was 3097.92 mg versus 1216.67 mg in the post FPC group (P < .1563). When comparing FPC's cost and implementation into both of our outpatient dialysis centers, this yielded a net savings of $296 751.49.

Assessment of Safety of Remdesivir in Covid -19 Patients with Estimated Glomerular Filtration Rate (eGFR) < 30 ml/min per 1.73 m^2

PURPOSE/OBJECTIVE:Safety of remdesivir in patients with renal impairment is unknown. Incidence of liver injury secondary to remdesivir is also unknown. The objective of this study is to assess the incidence of acute kidney injury (AKI) and to trend the liver enzymes during remdesivir treatment and change in eGFR from baseline to end of treatment as well as 48 h post completion of remdesivir therapy. METHODS:This is a retrospective chart review study including adult patients admitted with COVID-19 receiving remdesivir with a baseline eGFR < 30 ml/min per 1.73 m^2 from December 2020 to May 2021. The primary outcome was to assess the incidence of AKI and hepatic injury. The secondary outcome was to assess the efficacy of remdesivir defined by change in oxygen requirement. RESULTS:Seventy-one patients were included in the study. Patients experienced an improvement in eGFR from baseline (T0) to end of remdesivir treatment (T1), as well as 48 h after the end of the treatment (T2) ( + 30.3% and + 30.6% respectively, P < .0001). Creatinine reduced from baseline (T0) to T1 and T2 (-20.9% and -20.5% respectively, P < .0001). Creatinine clearance improved from baseline to T1 and T2 ( + 26.6% and + 26.2% respectively, p < .0001). Elevation of aminotransferase (AST) was observed at T1 ( + 2.5%, P  =  .727), however, AST reduction was seen at T2 (-15.8%, P  =  .021). Elevation in alanine transaminase (ALT) was observed at T1 and T2 ( + 25% and + 12%, P  =  .004 and P  =  .137 respectively). Both direct and total bilirubin remained stable and were not significantly changed from baseline. CONCLUSION/CONCLUSIONS:Our study showed that remdesivir use in renally-impaired patients with eGFR < 30 ml/min is safe. Remdesivir may be considered as a therapeutic option in this population with COVID-19 infection.
