Allergen immunotherapy and/or biologicals for IgE‐mediated food allergy: A systematic review and meta‐analysis
Bibliographic record
Abstract
BACKGROUND: There is substantial interest in immunotherapy and biologicals in IgE-mediated food allergy. METHODS: We searched six databases for randomized controlled trials about immunotherapy alone or with biologicals (to April 2021) or biological monotherapy (to September 2021) in food allergy confirmed by oral food challenge. We pooled the data using random-effects meta-analysis. RESULTS: We included 36 trials about immunotherapy with 2126 mainly child participants. Oral immunotherapy increased tolerance whilst on therapy for peanut (RR 9.9, 95% CI 4.5.-21.4, high certainty); cow's milk (RR 5.7, 1.9-16.7, moderate certainty) and hen's egg allergy (RR 8.9, 4.4-18, moderate certainty). The number needed to treat to increase tolerance to a single dose of 300 mg or 1000 mg peanut protein was 2. Oral immunotherapy did not increase adverse reactions (RR 1.1, 1.0-1.2, low certainty) or severe reactions in peanut allergy (RR 1,6, 0.7-3.5, low certainty), but may increase (mild) adverse reactions in cow's milk (RR 3.9, 2.1-7.5, low certainty) and hen's egg allergy (RR 7.0, 2.4-19.8, moderate certainty). Epicutaneous immunotherapy increased tolerance whilst on therapy for peanut (RR 2.6, 1.8-3.8, moderate certainty). Results were unclear for other allergies and administration routes. There were too few trials of biologicals alone (3) or with immunotherapy (1) to draw conclusions. CONCLUSIONS: Oral immunotherapy improves tolerance whilst on therapy and is probably safe in peanut, cow's milk and hen's egg allergy. More research is needed about quality of life, cost and biologicals.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
