RESUMEN
Background: Cefepime is used for the treatment of nosocomial infections and serves as a carbapenem-sparing agent for treating AmpC inducible bacteria. Cefepime induced neurotoxicity (CIN) is a well-documented adverse effect, although data describing the risk of CIN in patients with a history of seizures (HOS) remains limited. Objectives: The primary and secondary objectives were to compare the rates of CIN in patients with and without HOS and identify risk factors associated with CIN, respectively. Methods: This was a retrospective matched cohort study of patients admitted to University Hospital from January 2019 to December 2022 that were initiated on cefepime with and without a baseline HOS. Patients were matched at a rate of 1:1 by age (+/- 5 years), sex, and month of admission (+/- 1 month). Results: A total of 150 patients were included, 75 in each group. There was no statistically significant difference in CIN between the two groups (9 vs 7, P = 0.7923). The only risk factors associated with CIN were age >65 (OR, 5.8 [95% CI, 1.194-27.996]), acute kidney injury (AKI) during cefepime administration (OR, 13.8 [95% CI, 2.528-75.206]), and an intensive care unit (ICU) stay (OR, 8.6 [95% CI, 1.735-42.624]). Conclusion: There was no increased risk of CIN observed in patients with HOS. Patients age >65, AKI while receiving cefepime and those admitted to the ICU were 5.8, 13.8, and 8.6 times more likely to experience CIN. These results suggest that it may be safe to administer cefepime to patients with HOS in the appropriate clinical setting.
RESUMEN
PURPOSE: To evaluate the incidence of large bore hemodialysis catheter malfunction in the setting of COVID-19. MATERIALS AND METHODS: A retrospective review was performed of all patients who underwent placement of a temporary hemodialysis catheter after developing kidney injury after COVID-19 infection at our institution. Data collected included demographic information, procedure related information, and incidence of replacement due to lumen thrombosis. Groups were compared using students t-test for continuous variables and Fisher's exact test for nominal variables. RESULTS: Sixty-four patients (43M, mean age 63.2 ± 13.3) underwent placement of temporary hemodialysis catheter placement for kidney injury related to COVID 19 infection. Thirty-one (48.4%) of catheters were placed via an internal jugular vein (IJV) access and 33 (52.6%) of catheters were placed via a common femoral vein (CFV) access. Overall, 15 (23.4%) catheters required replacement due to catheter dysfunction. There were no differences in demographics in patients who required replacement to those who did not (p > 0.05). Of the replacements, 5/31 (16%) were placed via an IJV access and 10/33 (30.3%) were placed via a CFV access (p = 0.18). The average time to malfunction/replacement was 7.8 ± 4.8 days for catheters placed via an IJ access versus 3.4 ± 3.3 days for catheters placed via a CFV access (p = 0.055). CONCLUSION: A high incidence of temporary dialysis catheter lumen dysfunction was present in patients with COVID-19 infection. Catheters placed via a femoral vein access had more frequent dysfunction with shorter indwelling time.
