A retrospective study of the safety and efficacy of low molecular weight iron dextran for children with iron deficiency anemia.

BACKGROUND: Iron deficiency anemia (IDA) affects millions of children worldwide. Oral iron replacement is effective but often poorly tolerated. Intravenous iron has been demonstrated to have utility in all ages, but pediatric use remains limited. Low molecular weight iron dextran (LMWID) has a dosing range capable of replacing iron deficits in a single infusion and has been evaluated in small pediatric cohorts, but additional safety and efficacy data are limited. Here, we evaluate the safety and efficacy of LMWID in association with an electronic medical record (EMR)-based effort to optimize dosing. PROCEDURE: A retrospective IRB-approved investigation of LMWID utilization at a tertiary pediatric hospital between January 1, 2016 and March 31, 2020 was undertaken to evaluate the therapeutic efficacy and frequency/severity of infusion-related adverse event (AE) in children and adolescents receiving LMWID. Patient demographics and LMWID dosing characteristics were collected, and primary outcome measures included laboratory response and the incidence/severity of any infusion-related events. The utilization of an EMR-based nomogram for LMWID dosing was also evaluated. RESULTS: A total of 254 infusions for 191 patients were included (ages 0.7-20.9 years), most with IDA. LMWID replaced at least 75% of the estimated iron deficit in a single infusion for 76% of patients. The mean hemoglobin and ferritin increases were 2.1 g/dl and >100 ng/ml, respectively. Infusion-related AEs were rare, occurring in only 12/254 (4.7%) of infusions and 67% during the test dose; each rapidly resolved without long-term sequelae. No AEs occurred in those <10 years of age. Premedication use markedly decreased with nomogram use without a change in AE rate. CONCLUSIONS: In a large institutional cohort, LMWID was well tolerated in children and adolescents, with most patients having their total iron deficits relieved in a single infusion. These data support expanded use of LMWID in the management of pediatric iron deficiency.

Utilization trends and safety of intravenous iron replacement in pediatric specialty care: A large retrospective cohort study.

BACKGROUND: Iron deficiency is a common and clinically diverse hematologic disorder in childhood for which oral iron is often an infeasible or ineffective treatment option. Intravenous (IV) iron can be an efficient and highly successful means of iron replacement but its use has not been well-characterized on a large scale in pediatrics. PROCEDURE: All IV iron doses administered to patients for iron replacement therapy at a tertiary pediatric hospital from January 2010 through October 2016 were evaluated. Analyses included patient demographics, underlying medical conditions, and detailed information for each dose. Individual chart review was performed to identify infusion-related reactions. Nephrology patients as well as those patients 21 years or older at the time of the first infusion were excluded. RESULTS: A total of 1,088 doses of IV iron administered to 194 patients met inclusion criteria. A wide variety of specialties prescribed IV iron, with gastroenterology, hematology, and hospital medicine being the highest users in this cohort. A majority of patients (68%) required multiple infusions and dosing was highly variable, ranging from 1.3-1,030 mg per infusion. Premedication use was infrequent (10.3% of doses) and no severe infusion-associated reactions occurred. CONCLUSIONS: IV iron is commonly prescribed by certain pediatric specialties but there is little standardization in the indications, formulations, or dosing. These data suggest that IV iron should be considered a safe alternative for iron deficiency treatment in pediatrics when oral iron is either unsuccessful or contraindicated.

Retrospective review of the incidence of cytomegalovirus infection and disease after liver transplantation in pediatric patients: comparison of prophylactic oral ganciclovir and oral valganciclovir.

Cytomegalovirus (CMV) is the most common viral infection after solid organ transplantation (SOT). Safe and effective prophylactic regimens that decrease its incidence after SOT are essential for long-term graft survival. Although valganciclovir is not Food and Drug Administration-approved for CMV prophylaxis in liver transplant recipients, postmarketing studies have shown valganciclovir to be as effective as ganciclovir in high-risk adult patients undergoing SOT. Currently, data are lacking for pediatric liver transplantation. The purpose of this study was to compare the efficacy and safety of valganciclovir and ganciclovir for CMV infection prophylaxis in pediatric liver transplant recipients. This was a retrospective study of 56 pediatric liver transplant recipients who were prescribed either oral ganciclovir (n = 37) or valganciclovir (n = 19). Patients were followed until 200 days after transplantation or death. The primary outcome measure compared the rates of early-onset CMV infection and CMV disease in the 2 medication groups. Secondary outcome measures identified patient-specific factors that contributed to CMV acquisition and the incidence of late-onset CMV infection or disease. The rates of adverse drug effects and discontinuation were also evaluated. Early-onset CMV disease was documented in 0% of valganciclovir patients and in 5.4% of ganciclovir patients (P = 0.54). There were no statistically significant differences in the secondary outcomes. An increased incidence of late-onset CMV disease was seen in the valganciclovir group versus the ganciclovir group (22.2% versus 8.1%, P = 0.23). No differences in adverse events were reported. In conclusion, no statistically significant differences were found in the incidence of CMV infection or disease between patients receiving oral valganciclovir and patients receiving oral ganciclovir.

Increasing Activities of Daily Living Is as Easy as 1-2-3.

BACKGROUND: Human flora are the most common cause of bacteremia in immunocompromised patients. Activities of daily living (ADL), including oral care and daily chlorhexidine gluconate bathing, can lower the risk of infection. METHODS: To address ADL compliance in our pediatric oncology and bone marrow transplant patients, we adopted the ADL 1-2-3 initiative: daily chlorhexidine gluconate bath and linen change, at least 2 activities per day, and oral care 3 times per day. Using the Model for Improvement we created a standardized ADL process that involved all providers. Interventions included addressing ADL 1-2-3 compliance during rounds, establishing accountability in care delivery, an oral care order set and algorithm, daily text message reminders, and physician intervention with noncompliant and high-risk patients. RESULTS: With our interventions, we increased our median compliance with the all-or-none ADL 1-2-3 initiative from 25% to 66% in 90 days. We have sustained our median compliance to 75% sixteen months after implementation. The greatest impact on compliance was seen with text message reminders to staff to complete and document the ADL 1-2-3 components, designated roles and responsibilities, and physician discussion with noncompliant and high-risk patients. DISCUSSION: Oral care algorithm and order set, daily text message reminders, and physician intervention with noncompliant and high-risk patients has improved our compliance. Units where compliance with ADL participation is low can benefit from incorporating elements from this ADL 1-2-3 initiative.
