Cystic dystrophy of the duodenal wall associated with chronic alcoholic pancreatitis. Clinical features, diagnostic procedures and therapeutic management in a retrospective multicenter series of 23 patients.

AIM OF THE STUDY: The aim of this retrospective multicenter study was to collect data from patients with chronic alcoholic pancreatitis and cystic dystrophy of the duodenal wall in order to better understand the outcome after medical, endoscopic and/or surgical treatment. PATIENTS AND METHODS: The data from medical records of 23 patients consecutively seen in ten primary referral centers from January 1990 to July 2004 were studied. Clinical, biological, and endoscopic features as well as imaging findings were recorded. Response to treatment was noted. RESULTS: Twenty-three patients (20 men), aged 45 years (range: 30-66), with chronic alcohol intake, cystic dystrophy of the duodenal wall, and previously known (N=14) or simultaneously diagnosed (N=9) chronic pancreatitis were included. Symptoms most frequently encountered were abdominal pain (N=22) and weight loss (N=16). An abdominal ultrasound was available for 10 patients, abdominal computed tomography for 22, upper endoscopy for 18, and endoscopic ultrasonography for 22. Endoscopic ultrasonography enabled diagnosis of cystic dystrophy of the duodenal wall in 19/22 patients. Six patients were symptom-free after alcohol withdrawal. Seven patients received octreotide 200 to 400 microg per day, 5 of whom subsequently underwent surgery (71%). Fourteen patients out of 23 were operated on (61%), 11 of whom underwent pancreaticoduodenectomy and remained symptom-free for 47 months follow-up. Mean follow-up was 56 months (range: 2-78) for non surgical patients (39%) and 47 months (range: 12-108) for surgical patients (61%). CONCLUSION: Cystic dystrophy of the duodenal wall complicating chronic alcoholic pancreatitis may be the revealing sign of pancreatitis. Endoscopic ultrasongraphy is the most reliable imaging method for diagnosis. Pancreaticoduodenectomy is the most frequently employed definitive treatment.

Remission with ursodeoxycholic acid of type 1 autoimmune hepatitis resistant to azathioprine and steroids.

Combination therapy with steroids and azathioprine is the reference treatment for autoimmune hepatitis, but potential adverse effects are numerous and intolerance can occur. We report a patient with a well-documented type 1 autoimmune hepatitis intolerant to corticosteroids and azathioprine therapy, in whom eight years of ursodeoxycholic acid monotherapy was associated with biochemical and histological remission.

Azathioprine induced nodular regenerative hyperplasia in IBD patients.

Purine analogues are major drugs in the treatment of inflammatory bowel diseases (IBD). We present four cases of nodular regenerative hyperplasia of the liver (NRH) developed in patients with IBD treated with azathioprine. All patients had either abnormal liver tests and/or low platelet count. Although biochemical and hematological abnormalities regressed after azathioprine withdrawal, the long term evolution of the hepatic lesions (and the risk to develop further complications including portal hypertension) remains to be determined. Male gender seems to be a major risk factor by providing a predisposing pharmacogenetic profile of purine analogue metabolism. Clinicians should be aware of this serious complication which may occur with any of the purine analogues (azathioprine, 6-mercaptopurine, and 6-thioguanine).

[Acute pancreatitis and pancreatic reactions due to Salmonella. A study of 6 cases]. / Pancréatites aiguës et réactions pancréatiques à Salmonella.

Numerous infectious agents may induce acute pancreatitis. We report 6 cases of Salmonella-associated acute pancreatitis. Pathogenesis of this type of pancreatitis is related to multiple factors that may coexist in the same patient. The typical clinical picture consists in epigastric pain, nausea, vomiting, diarrhoea and fever. Imaging techniques often disclose minimal changes such as moderate swelling of a part or of the totality of pancreas. As outcome is usually good, conservative treatment and antibiotics may be sufficient to ensure recovery.
