RESUMO
Background and study aims: the mechanisms underlying acute pancreatitis have not been well elucidated. Over the last 20 years, there has been increasing awareness regarding the role played by oxidative stress in acute pancreatitis, but it is less well defined in human clinical trials. The aim of this study was to identify the relationship between antioxidants and acute pancreatitis
Patients and methods: we performed a cross-sectional trial on patients with mild acute pancreatitis. The study population consisted of 53 patients with mild acute pancreatitis and 55 healthy controls. Serum paraoxonase, arylesterase activity, total antioxidant status, total oxidant status and thiol levels were measured and oxidative stress index was calculated
Results: paraoxonase, arylesterase activity, thiol and total antioxidant status levels were significantly lower in the acute pancreatitis group than in the control group [p = .024, p < .001, p < .001, p = .010, respectively]. Oxidative stress index and total oxidant status levels were higher in the acute pancreatitis group than in the control group, but the difference was not statistically significant [p = .135, p = .253, respectively]
Conclusions: this study demonstrates that decreased antioxidant levels are associated with mild acute pancreatitis. No association was observed between mild acute pancreatitis and total oxidant status
RESUMO
Intravesical bacillus Calmette-Guerin (BCG) is used in patients with urinary bladder carcinoma. Although it is generally well tolerated, granulomatous hepatitis is a rare but serious complication. We report a 42-year-old man and a 56-year-old man who developed granulomatous hepatitis following intravesical BCG. One of them was treated successfully with antitubercular therapy; the other died because of BCG sepsis and multi-organ failure.
