Pancreatic necrosis is a diffuse inflammation of the pancreas with infectious etiology. Pancreatic necrosis occurs within the first 2 weeks of acute pancreatitis and develops in 10% to 30% of patients with acute pancreatitis. The necrotic pancreas can become secondarily infected with enteric gramnegative bacteria (such as E. coli), and disseminated infection may result from pancreatic necrosis.7,8...

Animal and human studies support the use of antibiotics for the prevention of infectious morbidity and mortality in severe ANP. The most effective antimicrobial agents are the fluoroquinolones, imipenem-cilastatin, and metronidazole, which achieve adequate penetration into pancreatic juice and necrotic tissue and inhibit the growth of enteric bacteria. Although a recent meta-analysis [185] suggested that prophylactic antibiotic administration reduces sepsis and mortality and this approach has been recommended by recent guidelines and consensus state-...

Patients predicted to follow a severe course require treatment of any cardiovascular, respiratory, renal, and metabolic complications. Aggressive fluid resuscitation is essential to correct intravascular volume depletion and maintain blood pressure. IV colloids may be required because fluid losses are rich in protein. Drotrecogin alfa may benefit patients with pancreatitis and systemic inflammatory response syndrome. IV potassium, calcium, and magnesium are used to correct deficiency states. Insulin is used to treat hyperglycemia. Patients with necrotizing pancreatitis may require antibiotics and surgical intervention. 

Removal of biliary tract gallstones with endoscopic retrograde cholangiopancreatography or surgery usually resolves AP and reduces the risk of recurrence. Surgery may be indicated in AP to treat pseudocyst, pancreatic abscess, and to drain the pancreatic bed if hemorrhagic or necrotic material is present.

Incidence of acute pancreatitis is steadily rising from year to year and according to world statistics, varies from 200 to 800 patients per million of population [1]. Some 15-20% of patients experience destructive, necrotic progression of acute pancreatitis [1,2]. Early toxemic and late septic complications of destructive pancreatitis are stiU...

The thiazides are sulfonamides and share cross-reactivity with other members of this chemical group. Photosensitivity or generalized dermatitis occurs rarely. Serious allergic reactions are extremely rare but do include hemolytic anemia, thrombocytopenia, and acute necrotizing pancreatitis. 

Physical examination of the abdomen reveals tenderness most marked in the epigastrium but sometimes present throughout. Bowel sounds are decreased or absent. Usually there are no masses palpable their presence most often indicates complications of AP, such as a pseudocyst or an abscess. In necrotizing pancreatitis the abdomen may be distended due to the intraperitoneal collection of fluid. The temperature is usually slightly elevated (100-101°F) in uncomplicated cases. Physical examination may reveal pleural effusion, especially on the left side. 

In severe acute pancreatitis, the patient may present with symptoms of dehydration including tachycardia and hypotension. In about 1 % of patients, a bluish color is present around the umbilicus (Cullen s sign) or in the flanks of the abdomen (Grey Turner s sign) as a result of necrotizing pancreatitis and collection of blood from the retroperitoneal space. 

An attempt to use acute-phase proteins as early markers of the differentiation of edematous from necrotizing AP was made by Rau et al. (R8), who assayed CRP concentration and human pancreatic-specific protein (hPASP) successively... 

Human pancreatic secretory trypsin inhibitor (hPSTI) can be potentially assayed as an indicator of necrotic complications in AP (Ol). This protein is an inhibitor of trypsinogen, which is produced in acinar cells in the quantity of approximately 2% of the potential content of trypsin in pancreas. Trypsin binds with its inhibitor hPSTI, then with AMG, and only this complex, trypsin-o 2-macroglobulin, is eliminated from plasma (B10). Pezzili (P3) suggests that early attempts to determine the severity of the AP process based on the measurement of hPSTI within 24 hr from the first sensations of pain show a sensitivity of 79%, whereas an increase in CRP concentration has a sensitivity of 29% only (Table 3). 

Poly-C-SpecificRibonuclease (P-RNase) (EC3.1.27.5). Warshawand Fournier (W3) showed that an increase in plasma enzyme activity of pancreatic P-RNase in patients with AP may indicate necrotic lesions, and is one of the few direct markers of pancreatic tissue injury (Nl, W4). Due to the time-consuming and cumbersome nature of the P-RNase assay procedure and the development of effective visualization techniques providing direct information on the structure of the inflamed pancreas, the diagnostic utility of the P-RNase assay has not been extensively studied (Table 3).

Some patients may experience hearing loss, which may accompany diabetes. Usually, type 2 diabetes is described in individuals with MELAS, although type 1 or insulin-dependent diabetes also may be observed. Palpitations and shortness of breath may be present in some patients with MELAS secondary to cardiac conduction abnormalities such as Wolff-Parkinson-White syndrome. Acute onset of gastrointestinal manifestations (e.g., acute onset of abdominal pain) may reflect pancreatitis, ischemic colitis, and intestinal obstruction. Numbness, tingling sensation, and pain in the extremities can be manifestations of peripheral neuropathy. Some patients may have the presentation of Leigh syndrome (i.e., subacute necrotizing encephalopathy).

As the management of liver transplantation has improved, absolute and relative contraindications have been established. Relative contraindications may question the success of LT in some cases. Obesity leads to an increased rate of postoperative complications, but it does not influence the survival rate. (396, 403) (s. tab. 40.16) Contraindications should also be considered in urgent LT due to acute liver failure - possibly accompanied by necrotizing pancreatitis, septic shock and problems with assisted respiration. Visceral inversion is not deemed to be a contraindication a successful LT was indeed carried out under such conditions by G.B. Rlintmalm et al. in 1993. 

Over a year after renal transplantation, a 48-year-old man, who took azathioprine, ciclosporin, and prednisolone, developed acute necrotizing pancreatitis (38). Improvement was obtained after azathioprine withdrawal, but he again took azathioprine and had similar symptoms within 30 hours after a single dose.
