Substantial variation was found in the duration and selection of antibiotic prophylaxis for patients with delayed sternal closure after cardiothoracic operation. Broad-spectrum antimicrobial agents and extended durations of antibiotic prophylaxis were not associated with benefits in the incidence of sternal wound infection and may increase the risk of adverse effects.
Dual antiplatelet therapies differed in both MACE and bleeds in a real-world setting of PCI. Prasugrel was associated with fewer MACE, whereas clopidogrel had fewer major bleeding events.
Background Standard dose ganciclovir (SD-GCV) for treatment of CMV infection/disease is 5 mg/kg every 12 hours, although higher doses (7.5–10 mg/kg every 12 hours) may be considered for resistant CMV. Literature on safety/efficacy of high dose GCV (HD-GCV) is limited. We sought to evaluate safety and clinical outcomes of SD-GCV vs HD-GCV strategies. Methods Retrospective single center study of adult SOT recipients with CMV viremia from 1/1/2017-1/31/2019 who received IV GCV therapy. Primary objective was to compare incidence of cytopenias between SD-GCV and HD-GCV. Secondary outcomes compared CMV viremia clearance, incidence of CMV disease and recurrent viremia within 30 days, granulocyte colony stimulating factor (G-CSF) use, and antiviral resistance testing rates. Results We evaluated 121 patients: 74 received SD-GCV, 47 received HD-GCV. Baseline characteristics were similar between groups. Most patients received a liver transplant (46% SD vs 36% HD) and had D+/R- CMV serostatus (55.4% SD vs 68% HD). Induction immunosuppression occurred in 75%, mostly with anti-thymocyte globulin. Median baseline CMV viral loads were similar (4620 IU/mL SD vs 7770 IU/mL HD, p=0.25). Incidence of cytopenias was similar between groups: leukopenia (43% SD vs 43% HD, p=0.96), neutropenia (15% SD vs 13% HD, p= 0.75), thrombocytopenia (24% SD vs 31% HD, p=0.62). HD-GCV did not significantly impact CMV clearance (HR: 0.79 [95% CI 0.52–1.21], p=0.27). There was no difference in incidence of CMV disease (35% SD vs 38% HD, p=0.72) or incidence of recurrent CMV viremia (15% SD vs 28% HD, p=0.098). G-CSF requirement was not different (23.7% SD vs 14.3% HD, p=0.295), however, patients on HD-GCV received more doses of G-CSF (median 2 SD vs 5 HD, p=0.001). More patients in HD-GCV group were tested for antiviral resistance: 15 (21%) SD vs 20 (43%) HD, p=0.01. Of these, there was no difference in rate of resistance detection (7/15 (47%) SD vs 11/20 (55%) HD, p=0.95). Conclusion Therapy with HD-GCV did not demonstrate increased incidence of cytopenias compared to SD-GCV, nor did we observe improved time to CMV clearance or incidence of CMV disease between groups. Opportunities exist for improving stewardship of antiviral resistance testing and use of G-CSF when considering HD-GCV therapy. Disclosures All Authors: No reported disclosures
Background: Clotrimazole troches are used as prophylaxis against oropharyngeal candidiasis post-transplant and have limited systemic absorption. Following several occurrences of tacrolimus concentration fluctuations after clotrimazole discontinuation, its use as prophylaxis was discontinued post-kidney transplant. Methods:We conducted a retrospective cohort study to evaluate the effect of clotrimazole prophylaxis on tacrolimus trough concentrations post-kidney transplant.The study included adult patients who received a kidney transplant at Cleveland Clinic Main Campus from August 1, 2019 to July 1, 2020 and were maintained on per-protocol, standard-dose tacrolimus through 90 days post-transplant. Patients were excluded if they received cyclosporine, systemic antifungals, strong CYP3A4 inhibitors or inducers, or a simultaneous multiorgan transplant. The primary objective was to compare tacrolimus trough concentrations before and after completion of clotrimazole prophylaxis. Secondary objectives were to compare the time to first post-transplant goal tacrolimus trough concentration, the rate of for-cause allograft biopsies within 90 days after transplant, and the incidence and type of candidiasis within 30 days after transplant, pre-and post-protocol change.Results: Following clotrimazole discontinuation, the median tacrolimus trough concentration decreased from 10.5 ng/ml (IQR 8.4-12.2) to 6.6 ng/ml (IQR 5-8.7, p < 0.0001).No statistically significant differences in the rate of for-cause allograft biopsies (4.9% vs. 9.7%, p = 0.264) or incidence of candidiasis (1.2% vs. 5.4%, p = 0.217) were observed between those who received clotrimazole and those who did not receive clotrimazole. Conclusions:Our study provides further evidence of a significant drug-drug interaction between tacrolimus and clotrimazole among kidney transplant recipients that can potentially lead to negative allograft outcomes.
