title: Severe chest pain in a pediatric ulcerative colitis patient after 5-aminosalicylic acid therapy.
abstract: Severe reactions to mesalamine products are rarely seen in pediatric patients. We report a case of a 12-year-old boy who had a severe cardiac reaction to a mesalamine product Asacol. Past medical history is significant for ulcerative colitis (UC) diagnosed at 9 years of age. Colonoscopy one week prior to admission revealed pancolitis. He was treated with Asacol 800 mg three times per day and prednisone 20 mg/d. He was subsequently admitted to the hospital for an exacerbation of his UC and started on intravenous solumedrol. He had improvement of his abdominal pain and diarrhea. The patient complained of new onset of chest pain upon initiating Asacol therapy. Electrocardiogram (ECG) revealed non-specific ST-T wave changes with T-wave inversion in the lateral leads. Echocardiogram (ECHO) revealed low-normal to mildly depressed left ventricular systolic function. The left main coronary artery and left anterior descending artery were mildly prominent measuring 5 mm and 4.7 mm, respectively. His chest pain completely resolved within 24-36 h of discontinuing Asacol. A repeat echocardiogram performed two days later revealed normal left ventricular function with normal coronary arteries (< 3.5 mm). Onset of chest pain after Asacol and immediate improvement of chest pain, as well as improvement of echocardiogram and ECG findings after discontinuing Asacol suggests that our patient suffered from a rare drug-hypersensitivity reaction to Asacol.
