Predictors of fluid overload in allogeneic hematopoietic cell transplant patients receiving post-transplant cyclophosphamide.

BACKGROUND: Fluid overload (FO) commonly occurs during hospitalization for allogeneic hematopoietic cell transplantation (HCT). Grade 2-4 FO is associated with day +100 non-relapse mortality.1 Post-transplant cyclophosphamide (PTCY) for graft-versus-host disease prevention requires aggressive IV hydration to prevent hemorrhagic cystitis. MATERIALS AND METHODS: This is a single-center, retrospective, observational study conducted at an academic medical center via electronic chart review. Included patients received allogeneic HCT followed by PTCY on days +3 and +4. Patients were excluded for age < 18 years or incarceration. Primary endpoints are incidence of Grade 2-4 FO and associated risk factors. Descriptive and inferential statistics (i.e., Fisher's exact test, multivariable regression analysis) were used. RESULTS: Of 97 patients screened, 95 were included and 2 were excluded due to absence of weight measurements needed to grade FO. Median age was 60 years, 66.3% were male, 91.6% received reduced-intensity conditioning, 72.6% received haploidentical HCT, 44.2% were ECOG 0, and 11.6% had diastolic dysfunction. Incidence of grade 2-4 FO was 33.7% (n = 32). Univariate analyses found age (continuous; p = 0.04) and BSA < 1.7 m2 (p = 0.006) as independent factors associated with grade 2-4 FO. Multivariable regression analysis found 3.3% higher risk with every 1-year increase in age ranging from f 20 to 78 years (OR 1.033, 95% CI 1.001, 1.006; p = 0.0453) and 82.8% lower risk with BSA ≥ 1.7 m2 (OR 0.172, 95% CI 0.051, 0.588; p = 0.005) after adjusting for co-variates. CONCLUSION(S): Increasing age and BSA < 1.7 m2 are risk factors associated with grade 2-4 FO during hospitalization for allogeneic HCT with PTCY.

Meperidine compared to morphine for rigors associated with monoclonal antibody-related infusion reactions.

INTRODUCTION: Infusion reactions, characterized by symptoms such as rigors, fever, and hypotension, are common adverse events that occur during monoclonal antibody (MAB) therapy. The treatment of rigors often involves opioids, most commonly meperidine, despite limited evidence supporting use in the setting of MAB infusions. This study aims to compare the efficacy and safety of intravenous (IV) meperidine and morphine is treatment of MAB-related rigors, filling a significant gap in the literature. METHODS: This was a single-center, retrospective cohort study which reviewed patients either inpatient or within outpatient infusion centers from January 2015 to January 2024. Patients receiving IV 2 mg morphine or 25 mg meperidine for MAB-related rigors were included. The primary outcome was defined as the number of opioid doses required for rigors ablation. Secondary outcomes included rates of naloxone administration and documented sedation. RESULTS: A total of 1251 administration events were screened, of which 127 and 26 rigor events were in the meperidine and morphine cohorts, respectively, were included. A majority of both cohorts required only one dose of either agent for rigors ablation with <20% of either cohort requiring 2 or more doses (p = 0.539). Low rates of sedation were observed in both groups. CONCLUSION: Both meperidine and morphine effectively manage MAB-related rigors within minimal safety concerns. These findings suggest that morphine is a suitable alternative to meperidine for this indication, which may influence future formulary decision, provide alternatives for drug shortage, and optimize supportive care for patients undergoing MAB therapy.

Optimizing quality of care in patients admitted with chronic obstructive pulmonary disease exacerbation.

Objectives: Adherence to Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) treatment is variable in the inpatient setting. This study evaluates appropriateness of therapy in patients admitted to an academic medical center for AECOPD. Methods: This was a single-center, retrospective, observational study. The primary endpoint was proportion of patients who received appropriate AECOPD treatment within 24 h. Secondary endpoints included mean length of stay (LOS) and time to administration (TTA) of pharmacotherapy, 30-day readmission rates, and proportions of various ancillary care received. Data were analyzed using descriptive and inferential statistics. Results: Of 533 screened admissions, 163 were included. Of those included, 55% (n = 90) received guideline-based therapy within 24 h of presentation. This group had significantly shorter mean LOS (3.48 ± 2.61 vs 4.53 ± 3.40 days, p = .026), fewer COPD-related readmissions (7 vs 14, p = .036), and numerically fewer all-cause readmissions (14 vs 19, p = .11). Mean LOS and TTA were 3.95 ± 3.02 days and 8.47 ± 12.77 h, respectively. Discussion: Timely and guideline-based delivery of medications was associated with shorter length of stay and fewer COPD-related readmissions. Establishing a standardized care plan through order set implementation may be one strategy to improve care and outcomes in AECOPD patients.
