Colony-stimulating factors have been shown to improve anti-disialoganglioside 2 (anti-GD2) monoclonal antibody response in high-risk neuroblastoma by enhancing antibody-dependent cell-mediated cytotoxicity (ADCC). A substantial amount of research has focused on recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) as an adjuvant to anti-GD2 monoclonal antibodies. There may be a disparity in care among patients as access to GM-CSF therapy and anti-GD2 monoclonal antibodies is not uniform.

Introduction: Endogenous granulocyte-macrophage colony-stimulating factor (GM-CSF), identified by its ability to support differentiation of hematopoietic cells into several types of myeloid cells, is now known to support maturation and maintain the metabolic capacity of mononuclear phagocytes including monocytes, macrophages, and dendritic cells. These cells sense and attack potential pathogens, present antigens to adaptive immune cells, and recruit other immune cells. Recombinant human (rhu) GM-CSF (e.

Article Synopsis
  • Sargramostim (rhu GM-CSF) is used to enhance immune responses and help recover from chemotherapy-induced neutropenia, but its effectiveness against invasive fungal diseases (IFDs) is not well studied.
  • A review of 15 pediatric patients with malignancies and IFDs treated with sargramostim showed a high response rate, with 92% of evaluable patients responding positively to treatment.
  • The literature review, including 50 cases, also indicated a strong response rate of 82%, suggesting sargramostim could serve as a promising adjunctive therapy for patients with hematological cancers and difficult-to-treat IFDs.*

Background: Sargramostim [recombinant human granulocyte-macrophage colony-stimulating factor (rhu GM-CSF)] was approved by US FDA in 1991 to accelerate bone marrow recovery in diverse settings of bone marrow failure and is designated on the list of FDA Essential Medicines, Medical Countermeasures, and Critical Inputs. Other important biological activities including accelerating tissue repair and modulating host immunity to infection and cancer the innate and adaptive immune systems are reported in pre-clinical models but incompletely studied in humans.

Objective: Assess safety and efficacy of sargramostim in cancer and other diverse experimental and clinical settings.

Article Synopsis
  • A study was conducted to evaluate if a standardized weaning protocol for methadone and lorazepam could shorten the weaning duration and hospital stays for patients on prolonged opioid and benzodiazepine infusions.
  • The research compared two groups of patients: 75 before the protocol implementation and 102 after it, focusing on their weaning times based on how long they had been receiving the medication.
  • Results showed significant reductions in the number of days patients spent on methadone and lorazepam for specific durations of infusion after the new protocol was introduced, without impacting hospital stays or causing more adverse events.

A retrospective chart review was done to evaluate the efficacy of a course of dexamethasone for pediatric patients hospitalized with a mild to moderate acute asthma exacerbation compared with a prednisone-based regimen. Patients were identified based on International Classification of Diseases (ICD-9 and ICD-10) discharge diagnosis codes for asthma and cross-referenced with pharmacy dispense reports during the study period of June 2011 to January 2016. Baseline characteristics were similar among the 2 groups.

Objectives: Children have decreased levels of antithrombin III (AT III) compared to adults. These levels may be further decreased during acute illness. Administration of exogenous AT III can increase anticoagulant efficacy.

Objectives: Evidence suggests palivizumab may be beneficial for respiratory syncytial virus (RSV) infection in pediatric patients, although it is only approved by the US Food and Drug Administration for RSV prophylaxis. The objective of this study is to compare outcomes among pediatric patients with RSV infection who received intravenous palivizumab and standard of care versus standard of care alone.

Methods: This is a retrospective, single-center cohort study conducted between November 2003 and October 2013.
