Ameliorating Atopy by Compensating Micronutritional Deficiencies in Immune Cells: A Double-Blind Placebo-Controlled Pilot Study.

BACKGROUND: Functional iron deficiency facilitates allergy development and amplifies the symptom burden in people experiencing allergies. Previously we selectively delivered micronutrients to immune cells with ß-lactoglobulin as carrier (holoBLG), resulting in immune resilience and allergy prevention. OBJECTIVE: The clinical efficacy of a food for special medical purposes-lozenge containing ß-lactoglobulin with iron, polyphenols, retinoic acid, and zinc (holoBLG lozenge) was assessed in allergic women. METHODS: In a randomized, double-blind, placebo-controlled pilot study, grass- and/or birch pollen-allergic women (n = 51) were given holoBLG or placebo lozenges over 6 months. Before and after dietary supplementation, participants were nasally challenged and the blood was analyzed for immune and iron parameters. Daily symptoms, medications, pollen concentrations, and well-being were recorded by an electronic health application. RESULTS: Total nasal symptom score after nasal provocations improved by 42% in the holoBLG group versus 13% in the placebo group. The combined symptom medication score during the birch peak and entire season as well as the entire grass pollen season improved in allergic subjects supplemented with the holoBLG lozenge by 45%, 31%, and 40%, respectively, compared with the placebo arm. Participants ingesting the holoBLG lozenge had improved iron status with increased hematocrit values, decreased red cell distribution width, and higher iron levels in circulating CD14+ cells compared with the placebo group. CONCLUSIONS: Targeted micronutrition with the holoBLG lozenge seemed to be effective in elevating the labile iron levels in immune cells and reducing the symptom burden in allergic women in this pilot study. The underlying allergen-independent mechanism provides evidence that dietary nutritional supplementation of the immune system is one of the ways to combat atopy.

Maintaining an Adult Hematology/Oncology Service at a Tertiary Care Center during the SARS-CoV-2 Pandemic: An Eight-Week-Experience with a Newly Implemented Procedural Plan.

Treatment of cancer patients has become challenging when large parts of hospital services need to be shut down as a consequence of a local COVID-19 outbreak that requires rapid containment measures, in conjunction with the shifting of priorities to vital services. Reports providing conceptual frameworks and first experiences on how to maintain a clinical hematology/oncology service during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic are scarce. Here, we report our first 8 weeks of experience after implementing a procedural plan at a hematology/oncology unit with its associated cancer center at a large academic teaching hospital in Germany. By strictly separating team workflows and implementing vigorous testing for SARS-CoV-2 infections for all patients and staff members irrespective of clinical symptoms, we were successful in maintaining a comprehensive hematology/oncology service to allow for the continuation of treatment for our patients. Notably, this was achieved without introducing or further transmitting SARS-CoV-2 infections within the unit and the entire center. Although challenging, our approach appears safe and feasible and may help others to set up or optimize their procedures for cancer treatment or for other exceedingly vulnerable patient cohorts.
