[Ulcerative ileocolitis induced by NSAID therapy]

A 67-year-old woman was admitted to our hospital for spasmodic abdominal pain, diarrhea, and general weakness. She had lost 5 kg of weight over the past few weeks. The patient had a 20-year history of chronic analgetic abuse, mainly consuming over-the-counter nonsteroidal anti-inflammatory drugs (NSAID).

Laboratory examination was remarkable for a low serum albumin (2.3 g/dl), an increased erythrocyte sedimentation rate of 70 mm/h, and a profound anemia of 8.5 g/dl. Ultrasound of the abdomen showed thickening of the colonic wall and distended colon loops filled with fluid. On colonoscopy several ulcerations from the sigmoid to the ileum were seen. Histologic examination showed a nonspecific ileocolitis.

After cessation of NSAID intake diarrhea stopped within a few days. Abdominal pain resolved, anemia improved and the patient gained weight. A second colonoscopy revealed healing of the colonic ulcerations. Additional examinations regarding differential diagnoses showed no pathological results. Clinical course and subsequent clinical and endoscopic controls revealing further improvement confirmed the diagnosis of an NSAID-induced ileocolitis.

This patient is a typical example for NSAID-induced colonic ulcerations. It should be recognized that NSAID induce ulcers not only in the upper gastrointestinal tract. A careful drug history may provide the clue for the cause of lower gastrointestinal tract ulcerations.
