A patient with a transient elevation of the serum carcinoembryonic antigen (CEA) associated with a benign disease was reported. The elevation of CEA was noted in the patient with low T3, T4 syndrome associated with malnutrition due to malabsorption syndrome induced by post-gastrectomy and chronic pancreatitis. Mild liver dysfunction and diabetes mellitus were also noted. The CEA level decreased as T3, T4 level and malnutrition were improved by administration of a massive digestive enzyme preparation. This inverse correlation between the serum CEA and serum T3, T4 levels suggested that high levels of the serum CEA can be found in the patient with malnutrition.

We have examined the possibility that selenium deficiency may underlie one or more of the following peculiarities of chronic pancreatitis in tropical as compared to temperate zones: much higher prevalence, propensity for pancreatic calculi, and high frequency of diabetes. Selenium was measured by graphite furnace atomic absorption spectrometry in sera from 20 healthy volunteers, 36 patients with chronic pancreatitis (calcific 35, diabetic 32), and 23 patients with primary forms of diabetes, from Madras, South India; results were compared with data from 41 controls and 37 patients with chronic pancreatitis (calcific 13, diabetes 8) from Manchester, North West, England. We conclude that (a) bioavailability of selenium is equally high in each geographic area; (b) decrement in serum selenium (p less than 0.001) is of a similar order in Manchester and Madras patients, which denies a connection with calculi formation or pancreatic exocrine failure (since the incidence of these two problems was substantially higher in the Madras series); and (c) selenium levels do not account for accelerated course to diabetes in tropical chronic pancreatitis.

A new kit for radioimmunoassay of serum phospholipase A2 (PLA2) with monoclonal antibody (S-0932, Shionogi, Osaka, Japan) was used to examine PLA2 levels in patients with various diseases. Patients with acute pancreatitis showed significantly increased serum PLA2 levels. In patients with chronic pancreatitis, significant correlations were observed between the levels of factors evaluated by the secretin test and serum PLA2 levels. In patients with pancreatic cancer, serum PLA2 levels varied with disease severity. Serum PLA2 concentrations were within the normal range in patients with other malignant tumors, diabetes mellitus, and chronic liver diseases but were increased in patients with chronic renal failure. S-Sepharose column analysis of sera showed a small peak of pro-PLA2 and a large peak of PLA2 in sera from patients with severe acute pancreatitis, but a large peak of pro-PLA2 in healthy controls and patients with other diseases. On G-100 gel filtration, high-molecular-weight PLA2 immunoreactivity was detected in sera of patients with chronic renal failure, whereas a single peak of PLA2 immunoreactivity coinciding with that of standard PLA2 was detected in sera of patients with acute pancreatitis. These results suggest that (a) measurement of serum PLA2 is clinically useful for diagnosis and monitoring of pancreatitis, (b) active PLA2 in the circulation is dominant in severe acute pancreatitis, and (c) the kidney may be the main site of PLA2 degradation or excretion.

In an effort to minimize the nutritional complications that follow resection of the pancreas for severe chronic pancreatitis, the authors have performed a duodenum-preserving total pancreatectomy in eight patients for severe unremitting pain requiring large doses of opiate analgesia. Good relief of pain was obtained in six patients (75%), in whom the quality of life was undoubtedly improved. There were no problems with the control of diabetes after this procedure in any of these patients, and no patient has suffered any hypoglycemic attacks requiring medical treatment. This improved control of the diabetic state is probably related to a more physiologic state of the upper digestive tract, enabling a normal food intake. The authors found the operation to be technically difficult, however, and although there were no post-operative deaths, major complications were encountered in four patients. These consisted of postoperative bleeding requiring reoperation (two patients), sepsis, and a duodenal fistula, which progressed to stenosis.

Glucose counterregulation and hormonal responses after insulin-induced hypoglycemia were investigated in six patients with diabetes mellitus secondary to chronic pancreatitis, in seven with insulin-dependent (type I) diabetes mellitus, and in seven healthy subjects. Glucose counterregulation was identical in type I patients and in the patients with chronic pancreatitis, whereas both groups had impaired glucose recovery compared with the healthy subjects. The patients with chronic pancreatitis had no glucagon response to hypoglycemia, whereas epinephrine increased significantly. In an additional experiment, glucose recovery did not occur after hypoglycemia during concomitant beta-adrenoceptor blockade in these patients. In conclusion, glucose counterregulation is preserved but slightly impaired in patients with diabetes secondary to chronic pancreatitis, and the combination of total glucagon deficiency and pharmacological blockade of the metabolic actions of circulating epinephrine abolishes glucose counterregulation after hypoglycemia.

A prospective study is presented of large groups of patients with primary and secondary (in patients with acute of chronic pancreatitis) diabetes. Clinical actual problems of differential diagnosis of these conditions using clinical and paraclinical methods of diagnosis. The authors describe the most difficult diagnostic situations and orientate the physicians how to manage them.

Insulin was withdrawn from 7 patients with Type I (insulin-dependent) diabetes and 4 patients with insulin-dependent diabetes secondary to chronic pancreatitis, both groups without residual beta-cell function. Median plasma glucagon concentrations rose slightly, but significantly after withdrawal of insulin in Type I diabetic patients (from 14 (range: 11-16) to 19 (14-25) pmol/l by 6 h), but not in the patients with secondary diabetes. This was accompanied by a significantly higher increase in blood glucose concentration from 5.1 (4.9-5.7) to 15.2 (12.9-18.1) mmol/l by 6 h in Type I diabetic patients compared with patients with secondary diabetes (from 4.9 (4.3-6.7) to 13.1 (10.9-13.5) mmol/l) (p less than 0.01). Beta-hydroxybutyrate increased to a similar extent in the two groups, whereas no significant increases were found in glycerol and lactate in any of the groups. Increased secretion of glucagon is not essential for the development of hyperglycemia and ketonemia in patients with diabetes secondary to chronic pancreatitis, but may augment the degree of hyperglycemia in Type I diabetic patients compared with patients having secondary diabetes.

The mechanisms of carbohydrate metabolism abnormality were studied in 128 patients suffering from chronic pancreatitis by means of simultaneous measurement in the blood of glucose, insulin, C-peptide and glucagon concentrations both on an empty stomach and after the glucose tolerance test (50 g glucose). Five types of the hormonal mechanisms of hyperglycemia were revealed, caused by derangement of beta-cells for the most part, more rarely by alpha-cells of the pancreas and impairment of interregulation of those cells in chronic pancreatitis. The rate of the hormonal mechanisms of carbohydrate metabolism abnormality was shown to depend on the gravity and duration of chronic pancreatitis whereas blood sugar and insulin response to intravenous injection of glucose in patients with chronic pancreatitis to have characteristic features in common to type I and II diabetes.

Xenotransplantation of the pancreatic islet cells was performed in 8 patients with chronic pancreatitis and concomitant diabetes mellitus, operated on the pancreas. In 2 patients, the rejection of the cells transplanted occurred. The causes of failure and possibilities for improving the technique are analysed.

Insulinemia, concentration of C-peptide and glucagon in the blood was studied in chronic hepatitis patients showing moderate tolerance disorders to glucose and diabetes mellitus developed against the background of chronic pancreatitis. Both groups showed hyperglucagonemia. Basal hypoinsulinemia and reduction of the C-peptide level revealed only in patients suffering of chronic pancreatitis with secondary diabetes mellitus. Reduced reaction of beta-cells of the pancreas to physiologic stimulation by pancreosozymin were observed also in less significant disorders of tolerance to glucose. The authors discuss the significance of changes in the sequential development of different degrees of disorders of the carbohydrate metabolism in patients with chronic recurrent pancreatitis.
