Introduction: While clinical practice guidelines (CPGs) for pediatric oncology infection prophylaxis and management exist, few data describe actual management occurring at pediatric oncology centers.
Methods: An electronic survey querying infection management practices in nontransplant pediatric oncology patients was iteratively created by the Children's Oncology Group (COG) Cancer Control and Supportive Care Infectious Diseases Subcommittee and sent to leaders at all COG institutions, limiting each site to one response to represent their institution.
Results: The response rate was 57% (129/227 institutions).

Congenital neutropenia (CoN) is a heterogeneous group of inborn errors of immunity (IEI) characterized by recurrent infections and early onset of neutropenia (NP). This study aimed to investigate the demographic and clinical data of children with CoN and idiopathic neutropenia (IN) in Morocco. We performed a retrospective study of patients with CoN and analyzed the clinical and laboratory findings of patients with CoN and IN diagnosed between 1999 and 2018 in a clinical immunology unit of a large pediatric hospital.

Sepsis and septic shock are major complications of febrile neutropenia (FN) in pediatric patients with cancer (PPCs). The aim of the present study was to determine the association of vitamin D (VD) and cathelicidin levels with sepsis and septic shock in PPCs with FN. A prospective cohort of PPCs with FN who had previously received cytotoxic chemotherapy was analyzed.

Autosomal recessively inherited variants in the JAGN1 gene lead to congenital neutropenia, early-onset bacterial infections, aphthosis and skin abscesses due to aberrant differentiation and maturation of neutrophils. In addition, bone metabolism disorders and a syndromic phenotype, including facial features, short stature and neurodevelopmental delay, have been reported in affected patients.

Glycogen Storage Disease Type Ib (GSD-Ib) is a rare autosomal recessive metabolic disorder caused by mutations in SLC37A4, leading to a deficiency in glucose-6-phosphate translocase. This disorder is characterized by impaired glycogenolysis and gluconeogenesis, resulting in clinical and metabolic manifestations. We report a three-month-old Moroccan female patient presenting with doll-like facies, hepatomegaly, dysmorphic features, and developmental delays.
