We aimed to investigate the impact of C-reactive protein (CRP), interleukin (IL)-6, leptin, cortisol, and caspase-3 on the decision of terminating planned abdominal repair in secondary peritonitis. Fifteen patients with peritonitis were enrolled into the study. Serum CRP, IL-6, leptin, cortisol, and peritoneal caspase-3 activities were measured. APACHE II scores at 48 hours (h) and age were significantly higher in non-survivors. A significant decrease was observed in caspase-3 activities of patients in whom ≤4 laparotomies were performed when compared with those who underwent >4 laparotomies. For patients who underwent ≤4 laparotomies, there was a significant difference in caspase-3 levels between 0 and 72 h. There was no significant difference in caspase-3 levels in non-survivors; caspase-3 levels were significantly lower in the survivors at 48 and 72 h. Changes in CRP, IL-6, leptin, and cortisol levels were not statistically significant. CRP, IL-6, leptin, cortisol, and caspase-3 are not valuable in discriminating the number of planned operations, even though there is a significant decrease in caspase-3 "within" survivors. The discriminative value of caspase-3 for closure should be evaluated in studies in which caspase-3 is monitored for a longer duration in a large number of patients.

Background: In this study, the effectiveness of dexpanthenol and coenzyme Q10 (CoQ10) on the healing of ischemic colon anastomosis was investigated. Methods: Forty eight male Wistar Albino rats were divided into four equal groups (Sham-S, Sham-I, DXP, Q10). Following full layer colon resection, single layer colon anastomosis, without creating ischemia, was performed on the Sham-S group. The same experimental model was performed on remaining groups after ischemia was created. Intraperitoneal dexpanthenol and CoQ10 was administered to the DXP and Q10 groups once a day for three days. Ten days later, all colon anastomoses were investigated histopathologically and biochemically, as well as their burst pressure values, in all sacrificed rats. Results: The highest burst pressure value was observed in the Sham-S group, decreasing from high to low in the DXP, Q10, and Sham-I groups, respectively (p = 0.008). Furthermore, tissue hydroxyproline (p = 0.001) level values were significantly different among the groups. Additionally, histopathological analysis revealed a significant difference among groups regarding reepithelization (p = 0.027) and polymorphonuclear leukocyte density (p = 0.022). Conclusions: This preliminary study has shown that ischemia-reperfusion injury may impair the healing of colon anastomosis and it has been concluded that dexpanthenol and CoQ10 may have positive effects on the healing of ischemic colon anastomosis in rat, although re-epithelization may be adversely affected using CoQ10.

Background and Objectives: During acute pancreatitis, leakage of pancreatic enzymes into the gland results in autolysis of the pancreas. The lungs are also involved in this process. This study aimed to investigate the therapeutic effects of esomeprazole on damaged pancreatic tissue and affected lung tissue in rats with acute pancreatitis. Materials and Methods: The 24 Wistar-Albino male rats were divided into three groups: Control group (2 mL 0.9% saline solution was given intraperitoneally, n = 8); PCT group (acute pancreatitis was induced and then 2 mL 0.9% saline solution was administered intraperitoneally, n = 8); ESM group (acute pancreatitis was induced and then 10 mg/kg esomeprazole was administered intraperitoneally, n = 8). Then, the lungs and pancreas were completely removed, and blood samples were taken from all rats for histopathological and biochemical examination. Results: Pancreatic edema, vacuolization, necrosis, and inflammation in the PCT group were higher than in the control and ESM groups. Alveolar edema, alveolar distension, alveolar PMNL infiltration, and alveolar wall thickness in the PCT group were higher than in the control and ESM groups. Furthermore, IL-β (F = 40.137, p < 0.001), TNF-α (F = 40.132, p < 0.001), MIP-2 (X² = 19.245, p < 0.001), ICAM-1 (F = 14.312, p < 0.001), NO (F = 25.873, p < 0. 001), amylase (F = 30.333, p < 0.001), and lipase (X² = 16.141, p < 0.001) values measured in serum were different among groups. Pairwise group comparisons revealed that IL-β, TNF-α, MIP-2, and amylase levels in the ESM group were lower than in the PCT group (p < 0.05). Conclusions: Esomeprazole could be recommended in clinical practice during acute pancreatitis treatment due to its therapeutic effects on damaged pancreatic and lung tissues secondary to pancreatitis in rats.
