Anaphylactic shock with methylprednisolone sodium succinate in a child with short bowel syndrome and cow’s milk allergy

Abstract

Abstract Background Medications with methyl-prednisolone sodium succinate containing lactose, which potentially contains traces of cow’s milk proteins (CMP), could cause allergic reactions or compromise treatment of acute allergic reactions in sensitized patients. Case presentation We describe the unusual case of a one-year-old child affected by short bowel syndrome and history of severe cow’s milk allergy (CMA) and anaphylactic reaction due to intravenous administration of methyl-prednisolone sodium succinate (Solu-Medrol 40 mg, Pfizer). He was admitted to our hospital for severe respiratory failure and was initially treated with methyl-prednisolone (Urbason 40 mg, Sanofi Aventis), then with methyl-prednisolone sodium succinate (Solu-Medrol 40 mg, Pfizer). After the intravenous administration of second steroid, immediate anaphylaxis was recorded and treatment was stopped. Antihistamine and epinephrine were required and symptom resolution occurred. Conclusion Children who are highly sensitive to milk may have severe allergic reactions also after exposure to CMP through a different administration route than the oral one. Patients who have food allergies need to pay particular attention to the prescription of drugs and their formulation.
