Purpose of review: Several novel immunotherapies have recently been reported for the treatment of cow's milk allergy (CMA). However, systematic methods for the selection of immunotherapy in clinical practice have not been investigated. In this review, we have provided suggestions for safe and effective immunotherapy for patients with CMA.
Recent findings: Recent studies on cow's milk immunotherapy, using lower target doses, heated or baked cow's milk, combination treatment with adjuvants, or various routes of immunotherapy, included school-aged children with severe allergies, infants, and patients with mild CMA. These patients were administered various maintenance doses for various time periods. In the selection of immunotherapy, it would be useful to consider the patient's age and CMA severity at baseline: threshold dose, history of cow's milk anaphylaxis, and cow's milk-specific IgE levels.
Summary: Considering the risks and benefits for patients with CMA, appropriate treatment should be selected based on the current evidence. Low-dose oral immunotherapy may be useful in clinical practice for school-aged children with severe CMA. Additional studies are needed to assess the indications for immunotherapy to select appropriate treatments in real-life settings.
