Whereas the clinical approach in pediatric cancer patients with febrile neutropenia is well established, data on non-neutropenic infectious episodes are limited. We therefore prospectively collected over a period of 4 years of data on all infectious complications in children treated for acute lymphoblastic or myeloid leukemia (ALL or AML) and non-Hodgkin lymphoma (NHL) at two major pediatric cancer centers. Infections were categorized as fever of unknown origin (FUO), and microbiologically or clinically documented infections. A total of 210 patients (median age 6 years; 142 ALL, 23 AML, 38 NHL, 7 leukemia relapse) experienced a total of 776 infectious episodes (571 during neutropenia, 205 without neutropenia). The distribution of FUO, microbiologically and clinically documented infections, did not significantly differ between neutropenic and non-neutropenic episodes. In contrast to neutropenic patients, corticosteroids did not have an impact on the infectious risk in non-neutropenic children. All but one bloodstream infection in non-neutropenic patients were due to Gram-positive pathogens. Three patients died in the context of non-neutropenic infectious episodes (mortality 1.4%). Our results well help to inform clinical practice guidelines in pediatric non-neutropenic cancer patients presenting with fever, in their attempt to safely restrict broad-spectrum antibiotics and improve the quality of life by decreasing hospitalization.
Background: Standardization in clinical practice may lead to improved outcomes. Unfortunately, little is known about the variability of non-pharmacological anti-infective measures in children with cancer.
Design and Methods: A web-based survey assessed institutional recommendations regarding restrictions of social contacts, pets and food and instructions on wearing face masks in public for children with standard- risk acute lymphoblastic leuk emia and acute myeloid leukemia during intensive chemotherapy.
Results: A total of 336 institutions in 27 countries responded to the survey (range, 1-76 institutions per country; overall response rate 61%). Most institutions recommend that patients with acute myeloid leukemia avoid indoor public places and daycare, kindergarten and school, whereas recommendations for patients with acute lymphoblastic leukemia differ considerably by institution. In terms of restrictions related to pets, there was a wide variability between institutions for both acute lymphoblastic and acute myeloid leukemia patients. Most, but not all institutions do not allow children with either acute lymphoblastic or acute myeloid leukemia to eat raw meat, raw seafood or unpasteurized milk. Whereas most institutions do not routinely recommend that patients with acute lymphoblastic leukemia wear face masks in public, advice on this matter varies for patients with acute myeloid leukemia.
Conclusions: The survey demonstrates that there is a wide variation in recommendations on non-pharmacological anti-infective measures between different institutions, countries and continents. This information may be used to encourage harmonization of supportive care practices and future clinical trials.
