Doxycycline-induced oesophageal ulcer in a teenager: A case report

Esophageal Ulceration Following the Ingestion of a Single Dose of Doxycycline: A Case Report

Doxycycline is one of the medications that cause drug-induced esophagitis. This condition occurs due to prolonged contact of the medications with the esophageal mucosa, leading to erosion, ulcers, and, in some cases, stricture of the esophagus. Chest pain, dysphagia, and odynophagia are the most common symptoms. Endoscopy is the gold standard for confirming the diagnosis. The treatment consists of stopping the offending medication and starting proton pump inhibitors (PPIs) and sucralfate. Herein, we describe a middle-aged man who presented with severe chest pain, odynophagia, and dysphagia that started two hours after ingesting the first doxycycline pill. An endoscopy showed multiple longitudinal ulcers in the distal esophagus. Symptoms significantly improved after starting a PPI and sucralfate, and feeding was resumed two days later. A follow-up with endoscopy after two months reported completely healed esophageal ulcers. In conclusion, doxycycline-induced esophageal injury is often an underdiagnosed and underreported condition. Physicians and patients should be more aware of doxycycline's detrimental effect on the esophagus, as it can induce esophageal ulceration even after a single dose if not administered properly. Therefore, all patients prescribed oral doxycycline should receive appropriate instructions to minimize this side effect.

Esophageal brucellosis? Straight to the goat

We report the case of a 58-year-old immunocompetent man from Algeria, who presented to the hospital with fever and hepatic cytolysis. Abdominal computed tomography scan showed a homogeneous splenomegaly and a hypodense 12-mm mass on the posterior wall of the esophagus. After ruling out tuberculosis, the patient was diagnosed with brucellosis. Patient was cured after receiving 6 weeks of oral doxycycline and intravenous gentamicin during the 7 first days of therapy. Such treatment was considered as an acceptable alternative of the recommended first-line therapy. This case illustrates the diagnostic issues in the context of an authentic brucellosis presenting as upper gastrointestinal symptoms, with impaired general condition.
