The Influence of Non-steroidal Anti-inflammatory Drugs on Clinical Outcome in Patients with Bleeding Peptic Ulcers / 대한소화기학회지

BACKGROUND/AIMS: We conducted this study to find the clinical characteristics of ulcer bleeding that occurred in patients who had been taking non-steroidal anti-inflammatory drugs (NSAIDs) and to evaluate the influences of NSAIDs on clinical outcomes. METHODS: Between January 2000 and December 2002, a total of 310 patients with ulcer bleeding were analyzed. Study group composed of 49 patients who had taken NSAIDs regularly for at least 4 weeks before the admission. Other 261 patients who had not taken NSAIDs were classified as control group. Relevant informations were obtained from the medical records. RESULTS: Of the NSAIDs group, aspirin was the most common medication. The mean age and the proportion of females in the NSAIDs group were significantly higher than those of the control group. Prevalence of co-morbid illness was significantly higher in the NSAIDs group than in the control group (85.7% vs 30.7%, p<0.001). The severity of bleeding which was assessed by hemoglobin level at presentation, amount of transfusion, and duration of admission, was not different between two groups. There were no significant differences in frequency of re-bleeding, urgent surgery, and mortality. CONCLUSIONS: Ulcer bleeding among patients taking NSAIDs occurred more frequently in older females with co- morbid illness. However, NSAIDs is not associated with higher morbidity and mortality.

Ulceras gástricas sangrantes y hepatitis aguda: dos reacciones adversas simultáneas por nimesulida en un caso / Bleeding gastric ulcers and acute hepatitis: 2 simultaneous adverse reactions due to nimesulide in 1 patient

A 66 year-old obese woman with arthrosis, self-medicated with oral nimesulide, 200 mg daily. After 6 weeks she developed nausea, jaundice and dark urine. Two weeks later she had recurrent hematemesis and was hospitalized. Besides obesity and anemia her physical examination was unremarkable. An upper GI endoscopy revealed 3 acute gastric ulcers and a 4th one in the pyloric channel. Abdominal ultrasonogram showed a slightly enlarged liver with diffuse reduction in ecogenicity; the gallbladder and biliary tract were normal. Blood tests demonstrated a conjugated hyperbilirubinemia (maximal total value: 18,4 mg/dl), ALAT 960 U/l, ASAT 850 U/l, GGT 420 U/l, alkaline phosphatases mildly elevated, pro-time 49 percent and albumin 2.7 mg/dl. Serum markers for hepatitis A, B and C viruses were negative. ANA, AMA, anti-SmA, were negative. Ceruloplasmin was normal. A liver biopsy showed bridging necrosis and other signs of acute toxic liver damage. Gastric ulcers healed after conventional treatment and hepatitis subsided after 2 months leaving no signs of chronic liver damage. The diagnosis of toxic hepatitis due to nimesulide was supported by the time-course of drug usage, sex, age, absence of other causes of liver disease, a compatible liver biopsy and the improvement after drug withdrawal. Peptic ulcers or toxic hepatitis have been previously described as independent adverse reactions in patients taking nimesulide or other NSAIDs but their simultaneous occurrence in a single patient is a unique event that deserves to be reported

Gastric mucosal cellular changes induced by indomethacin (NSAID) in male albino rats.

Indomethacin (2 mg/100 g body weight), induces haemorrhagic gastric ulcers in albino rats. The incidence and severity of ulceration increased with starvation period. Indomethacin caused little or no effect on the cellular and the nuclear diameter of parietal and chief cells while reduction was observed in mucus and endocrine cells. The effect was enhanced with increased duration of starvation. Both mucous and endocrine cells decreased in their number after 72 hr of starvation. Thus prolonged starvation enhanced the gastric mucosal damage induced by indomethacin.
