Objective: To determine the influence of allopurinol and nimesulide in the protection of the pancreas from acute ischemia-reperfusion (I/R) injury.
Materials And Methods: A total of 30 rabbits were divided into 3 groups, group A: acute I/R only; group B: allopurinol (30 mg/kg) was administered intravenously 10 minutes before ischemia; group C: nimesulide (50 mg/kg) was given intraperitoneally 20 minutes before ischemia. Neopterin and superoxide dismutase (SOD) levels were examined. Pancreatic biopsies were obtained for electron microscopy study.
Results: The mean neopterin concentrations in group A are 3.56 ± 3.41, 7.74 ± 3.59, and 8.94 ± 2.86 ng/mL, respectively, in the stabilization, ischemia, and reperfusion phases; group B: 3.40 ± 3.03, 7.45 ± 8.89, and 10.64 ± 7.47 ng/mL; and group C: 3.41 ± 2.71, 5.67 ± 2.76, and 4.34 ± 2.87 ng/mL. The mean SOD concentrations in group A are 4.25 ± 1.79, 4.48 ± 1.60, and 5.57 ± 1.15 ng/mL; group B: 4.32 ± 0.81, 5.08 ± 1.10, and 4.45 ± 1.31 ng/mL; and group C: 4.10 ± 0.99, 5.23 ± 1.60, and 3.72 ± 1.30 ng/mL. Histopathology showed the least deterioration in group C.
Conclusion: Nimesulide is more efficient than allopurinol in protecting pancreas from acute I/R injury.

We report the case of a 59-year-old woman with a history of smoking, hypertension, and prior surgeries. She presented with acute right upper quadrant abdominal pain radiating to the back. Laboratory tests revealed elevated liver enzymes and imaging studies (CT and MRCP) showed a dilated common bile duct.

Treating acute rejection of a pancreas transplant in a severely immunocompromised patient with viral opportunistic infection is challenging due to the balance of rescuing from rejection without worsening the morbidity of infection and prolonging the infection episode. We present a case involving a pancreas-after-kidney transplant in a patient with CMV high-risk discordance (donor positive/recipient negative) and chronic lymphopenia who developed difficult-to-treat CMV disease approximately six months after pancreas transplant. Following the withdrawal of the antimetabolite due to the persistent CMV DNAemia and lymphopenia, the patient experienced acute pancreas rejection without adequate and sustained response to treatment with steroids and Thymoglobulin.

Background: Post-pancreatectomy acute pancreatitis (PPAP) is an early acute inflammatory process of the pancreatic remnant that is associated with a series of downstream pancreas-specific complications. This study aimed to investigate the relationship between postoperative serum C-reactive protein (CRP) levels and the occurrence of PPAP after pancreaticoduodenectomy (PD).
Methods: Consecutive patients who underwent PD between January 1, 2020, and May 31, 2022, were retrospectively analyzed.

Background And Aims: Previous studies have confirmed that alcohol can increase the sensitivity of the pancreas to stressors and exacerbate the severity of pancreatitis when excessive alcohol intake is combined with other causes. In the current work, this study attempted to explore how does alcohol regulate cerulein-induced acute pancreatitis, especially before inflammation occurs.
Methods: Proteomics was performed to analyze the differentially expressed proteins in pancreatic tissues from a rat model of pancreatitis.

Objectives: Hypertriglyceridemia-associated acute pancreatitis (HTG-AP) is one of the most common etiologies of acute pancreatitis (AP) worldwide. Compared to other etiologies, patients with HTG-AP may develop more severe AP, but previous studies yielded controversial conclusion due to the lack of adequate adjustment for the confounders. Therefore, this study aimed to examine the possibility and risk factors of developing severe AP in HTG-AP.
