The possible risk factors for failure of medical therapy were examined in 23 patients with pancreatic ascites or effusion. The ascites or effusion resolved completely in 10 patients after a mean (+/- SEM) of 30 +/- 2 days of conventional medical treatment. In five patients in whom conventional medical therapy failed, the addition of an octreotide (SMS 201-995) analogue to the medical therapy led to a resolution of the ascites (three patients) or effusion (two patients). Six patients underwent surgery after failed medical therapy, one patient died while receiving conservative therapy, and one patient refused hospital treatment. Serum sodium and albumin levels were significantly lower, and the ratio of total fluid protein to total serum protein was significantly higher in the group that failed to heal in response to conventional medical therapy. Nine of 11 patients with mild to moderately severe chronic pancreatitis healed in response to conservative therapy. Only one of 10 patients with advanced pancreatitis healed in response to conventional medical therapy. Our results suggest that a selective surgical approach is warranted to treat pancreatic ascites and effusion. In patients with mild or moderately severe pancreatitis, medical therapy is recommended. Patients with advanced pancreatic disease should be selected for early surgery. Octreotide may be useful in the patient in whom surgery may be associated with a prohibitive morbidity or mortality.

A chemical-physical and morphological examination of 109 pleural samples taken from 66 patients showed that the most reliable laboratory tests for discriminating between an exudate and transudate were specific gravity, total effusion protein content and the effusion/serum protein ratio, while LDH and cell number seem less important. In the differential diagnosis of pleuritis, pleural fluid amylase assays are important only if certain well-defined diseases are suspected (particularly pancreatitis). In this case the assay is irreplaceable. Glucose assay may be carried out for a wider range of complaints although a review of the literature shows it to be always below 30 mg, particularly in cases of rheumatoid arthritis. A cytological examination offers a pathognomonic guide in the case of tumours and as a back-up to other checks for many other complaints.

To study the source and role of circulating phospholipase A2 (PLA2) catalytic activity we monitored the serum from patients with necrotizing pancreatitis (n = 8), diffuse peritonitis (n = 6), and multiple injuries (n = 11). Immunoreactive PLA2 serum protein concentration was analysed using a fluoroimmunoassay based on an antibody against human pancreatic PLA2. Serum PLA2 catalytic activity was analysed using a radiochemical method based on a substrate with tritiated palmitic acid in beta position. In necrotizing pancreatitis immunoreactive PLA2 and PLA2 catalytic activity both increased. Obviously, in necrotizing pancreatitis the major part of serum catalytic activity stems from the pancreas. In patients with diffuse peritonitis and multiple injuries, as a rule, immunoreactive phospholipase A2 serum concentration appears to be within the normal range. In contrast, in these patients we demonstrated high serum catalytic PLA2 activity comparable to that in necrotizing pancreatitis. The source of catalytic PLA2 activity in peritonitis and multiple injuries seems not to be the pancreas. There was a correlation between pulmonary insufficiency and serum PLA2 catalytic activity in patients with necrotizing pancreatitis, peritonitis, and multiple injuries.

Serial serum amylase and blood glucose levels were measured in 68 hypothermic (rectal temperature 35 degrees C or less) patients, including 15 who had hypothermic myxoedema (serum protein bound iodine 3.5 mug/100 ml or less). Raised amylase levels were found in 34 patients and probably reflected a mild acute pancreatitis. The high amylase levels correlated with low arterial PO(2) levels and significantly with high arterial PCO(2) levels and the base deficit but not with the severity or duration of the hypothermia. The acute pancreatitis does not explain why hypothermic patients with myxoedema have a poorer prognosis than those who are euthyroid. The pancreatitis occasionally contributed to the development, sometimes delayed, of diabetic ketoacidosis, blood glucose levels of over 120 mg/100 ml being found in 20 patients. There was a significant correlation between the raised serum amylase levels and the hyperglycaemia. Hypoglycaemia, sometimes profound, was found in 12 patients.

Elevated plasma viscosity is a predictor of atherosclerotic vascular disease and is a potential mechanism by which hypertriglyceridemia increases cardiovascular risk. Previous studies of plasma viscosity reduction in hypertriglyceridemic patients used medications that lowered both triglyceride and fibrinogen levels. Because fibrinogen is a major determinant of viscosity, it is unclear whether triglyceride reduction alone is sufficient to reduce plasma viscosity. The purpose of this study was to determine whether triglyceride-lowering therapy reduces plasma viscosity. This was a prospective study of 24 adult patients with severe hypertriglyceridemia (> or = 5.67 mmol/l). Fasting lipid, total serum protein, fibrinogen, plasma viscosity and serum viscosity levels were measured before and after therapy with 1200 mg/d of gemfibrozil. Triglyceride levels decreased by 70% (P < 0.001). Mean plasma and serum viscosity levels decreased by 0.082 mPa/s (P = 0.003) and 0.086 mPa/s (P = 0.013), respectively. Fibrinogen levels did not change significantly. Triglyceride-lowering therapy reduced plasma and serum viscosity without changes in fibrinogen levels. Since serum samples are deplete of fibrinogen, the serum viscosity reduction observed is corroborative evidence for an independent effect of triglyceride-lowering therapy on plasma viscosity. This observation provides a physiological rationale for triglyceride-lowering therapy in patients at risk for atherosclerotic vascular disease, the chylomicronemia syndrome and pancreatitis.

Has early jejunal glutamine-rich diet any advantage in the treatment of patients suffering from acute pancreatitis and after oesophagectomy? Eleven patients suffering from necrotizing pancreatitis and 23 patients operated on radically for esophageal cancer were fed intra jejunally with glutamine-rich Stresson Multi Fibre diet. Eight patients with necrotising pancreatitis and 13 oesophagectomy patients were fed with glutamine-poor Nutrition Multi Fibre. Nutritional status, serum proteins, acute phase proteins, immune-globulins, complement components (C3, C4), the ratio of subsets of peripheral lymphocytes were analysed on the 1st, 2nd, 4th and 10th days. Serum protein parameters were measured by laser nephelometry. CD cell surface antigen expression was measured with flow cytofluorometry, activity of phagocytes with whole blood chemiluminescences. Laboratory parameters showed an improvement during the 10-day-treatment in both diet types, but significant improvement could be measured only in patients with necrotizing pancreatitis and fed with Stresson Multi Fibre: IgG (p < 0.05), serum protein (p < 0.02), prealbumin (p < 0.05), retinol binding protein (p < 0.03). The different diets did not cause difference in the laboratory results of the oesophagectomy patients. Early immune-enhancing diet improved serum proteins, acute phase proteins and immunoglobulins significantly in necrotizing pancreatitis. The length of hospital stay also decreased.

Portal vein thrombosis is a rare complication accompanied with acute pancreatitis or cholangitis/cholecystitis. The main pathogenesis of portal vein thrombosis in pancreatitis or cholangitis/cholecystitis are suggested to be venous compression by pseudocyst and an imbalance between the blood coagulation and fibrinolysis. In this case report, we experienced a 63 year old male who developed portal vein thrombosis later in the course of the treatment of acute gallstone pancreatitis with cholangitis/cholecystitis without any symptom or sign. The diagnosis of portal vein thrombosis was given on follow up CT scan and serum protein S activity was decreased to 27% in laboratory study. Immediate anticoagulation therapy with heparin and thrombolytic therapy with urokinase and balloon dilatation were performed. Despite the aggressive treatment, complete reperfusion could not be obtained. With oral warfarin anticoagulation, the patient showed no disease progression and was discharged. We report a case of portal vein thrombosis as a complication of acute pancreatitis and cholangitis/cholecystitis with a review of literatures.

Twenty-four patients with acute severe pancreatitis were randomised to receive total parenteral nutrition for 7 days with one of two isocaloric (35 kcal/kg/day) and isonitrogenous (0.16 g/kg/day) programmes containing either a low (15.5% w/w (control group)) or a high (57%) content of branched chain amino acids (BCAA (BCAA group)). During treatment, the nitrogen balance was similar in both groups. The concentrations of serum protein, albumin, prealbumin and retinol-binding protein did not differ between the groups. The plasma concentrations of BCAA measured 2 h after discontinuation of amino acid infusions rose in the BCAA group. In urine, only the concentrations of valine increased as compared with those of control patients. Serum glucose levels were higher in the BCAA group than in the control group, although the BCAA group received slightly more insulin than the control group in order to keep the blood glucose concentration below 10 mmol/l. The results suggest that BCAA-enriched solutions may stimulate gluconeogenesis without affecting catabolism.

IgG4-related systemic disease is a new clinical entity with a large variety of clinical symptoms that can affect almost all organs. The best known manifestations are retroperitoneal fibrosis and autoimmune pancreatitis. We present 3 patients aged 71, 83 and 70 years, with malaise, fatigue and swellings suggestive of a malignancy. However, histopathology of these swellings showed infiltration with plasma cells. Increased serum IgG4-levels confirmed the diagnosis 'IgG4-related systemic disease'. All patients responded well to treatment with glucocorticoids. IgG4-related systemic disease is often mistaken for malignancy because of similar presenting symptoms. The diagnosis can easily be confirmed by high serum protein levels, high serum IgG4-levels and infiltrates of IgG4-positive plasma cells. Response to treatment with glucocorticoids is good, as is the prognosis. IgG4-related systemic disease should be part of the differential diagnosis when patients present with malaise, high protein-levels and multi-organ involvement. Rapid diagnosis can prevent unnecessary surgical procedures for malignancy.

Autoimmune pancreatitis (AIP) is defined by characteristic lymphoplasmacytic infiltrate, ductal strictures and a pancreatic enlargement or mass that can mimic pancreatic cancer (PaCa). The distinction between this benign disease and pancreatic cancer can be challenging. However, an accurate diagnosis may pre-empt the misdiagnosis of cancer, allowing the appropriate medical treatment of AIP and, consequently, decreasing the number of unnecessary pancreatic resections. Mass spectrometry (MS) and two-dimensional differential gel electrophoresis (2D-DIGE) have been applied to analyse serum protein alterations associated with AIP and PaCa, and to identify protein signatures indicative of the diseases. Patients' sera were immunodepleted from the 20 most prominent serum proteins prior to further 2D-DIGE and image analysis. The identity of the most-discriminatory proteins detected, was performed by MS and ELISAs were applied to confirm their expression. Serum profiling data analysis with 2D-DIGE revealed 39 protein peaks able to discriminate between AIP and PaCa. Proteins were purified and further analysed by MALDI-TOF-MS. Peptide mass fingerprinting led to identification of eleven proteins. Among them apolipoprotein A-I, apolipoprotein A-II, transthyretin, and tetranectin were identified and found as 3.0-, 3.5-, 2-, and 1.6-fold decreased in PaCa sera, respectively, whereas haptoglobin and apolipoprotein E were found to be 3.8- and 1.6-fold elevated in PaCa sera. With the exception of haptoglobin the ELISA results of the identified proteins confirmed the 2D-DIGE image analysis characteristics. Integration of the identified serum proteins as AIP markers may have considerable potential to provide additional information for the diagnosis of AIP to choose the appropriate treatment.
