Skin rash, eosinophilia, and renal impairment in a patient recently started on allopurinol

Allopurinol is a hypoxanthine analog which inhibits xanthine oxidase, it is a widely used medication for the treatment of hyperuricemia and gout. Allopurinol-induced drug-induced rash with eosinophilia and systemic symptoms syndrome is an infrequent, life-threatening adverse reaction of allopurinol therapy that is remarkable for the higher mortality rate with the use of allopurinol than with the use of another agent. We present a case of a 62-year-old male with a history of chronic kidney disease stage 3, hypertension and gout who developed skin rash, eosinophilia, and renal impairment 2 weeks after he was started on allopurinol therapy for gout. Allopurinol was stopped, and the patient was started on steroids. This case emphasizes that although allopurinol is commonly used the drug for the treatment of gout. However, it can be associated with serious life-threatening complications. Therefore, care should be taken when prescribing allopurinol, and it should be prescribed only for the appropriate indications

A Rare Case of Embolic ST-Elevation Myocardial Infarction in an Adult Patient With Repaired Hypoplastic Left Heart Syndrome

A 24-year-old male with past medical history of hypoplastic left heart syndrome and staged reconstructive surgery in infancy culminating in the Fontan circulation presented to the hospital with a chief complaint of chest pain described as an elephant sitting on his chest. Initial 12-lead electrocardiogram revealed 2-mm ST segment elevation in inferior leads, 3-mm ST-segment elevation in anterolateral precordial leads V3 and V4, and 2-mm ST-segment elevation in V5 and V6, with right axis deviation. He was transported emergently to the cardiac catheterization laboratory where coronary angiography revealed complete occlusion of multiple anomalous branches of the right coronary system with hazy appearance suggesting the presence of thrombotic material. An aspiration catheter was used successfully to reestablish TIMI grade III flow. The patient was treated with aspirin, brilinta (ticagrelor), and anticoagulation with vitamin K antagonism to prevent recurrent thromboembolic complications
