Managing a Patient Presenting With Chest Pain and Gastrointestinal Complaints Using Dupilumab
Abstract
Adverse drug reactions or adverse drug events account for a significant proportion of emergency department visits among children and adolescents. Unfortunately, rare reactions to medications may go unnoticed by clinicians due to a lack of reporting to drug surveillance and monitoring programs. We present the case of an 18-year-old male who visited the emergency department on two separate occasions after receiving dupilumab injections for his atopic dermatitis. Ten days prior to his presentation, he was evaluated in the emergency room for the onset of chest pain, five days following his first dupilumab injection. Investigations in the interim revealed no cardiac pathology. He presented with a complaint of severe abdominal pain associated with nausea and vomiting several hours after receiving his second dupilumab injection. Investigations for causes of acute gastrointestinal or anaphylactic reactions only revealed mild leukocytosis and hypokalemia. A definitive diagnosis of hypersensitivity reaction, such as anaphylaxis or serum-sickness-like reaction, could not be made at either emergency visit due to the lack of objective findings and few similar reported cases. However, the timing of each event made an adverse reaction highly suspicious as the inciting factor of this patient's symptoms. He received oral potassium, ketorolac, and ondansetron for headache and ongoing nausea respectively. He was discharged home within a few hours after his symptoms had resolved. The limited…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
