The authors examined 40 patients with chronic ischemic pancreatitis without concomitant pathology of the alimentary organs in order to define the features of the disease clinical picture and progress. It was found that patients with disseminated atherosclerosis, especially when it is coupled with essential hypertension, and with extravasal stenosis of the celiac trunk are predisposed to the development of chronic ischemic pancreatitis. Factors promoting pancreatic ischemia include abnormalities of the blood rheological properties seen in vascular pathology and alimentary hyperlipidemia.

The degree of hyperlipidemia, hyperthyrosinemia, hyperserotoninemia and enhanced release of bradykinin from kininogen in patients with chronic recurrent pancreatitis was found to be decreased upon the attainment of a clinical remission. In patients with more considerable and more stable metabolic disorders, the incidence of exacerbations and the rate of progression of pancreatic, enzyme-secretory deficiency appeared, according to the data of a 8-year follow up, greater than in those with lesser degree and resistance of metabolic shifts.

Hyperlipemia in an acyanotic patient with diabetic ketoacidosis, alcoholism, and pancreatitis produced a falsely elevated concentration of methemoglobin (19 percent) and a lower-than-expected oxygen saturation measured with an automated spectrophotometer (IL-282 CO-Oximeter). In addition, there was a "normal" hemoglobin level despite a low hematocrit reading. In vitro studies showed that hyperlipemia corresponding to triglyceride levels of 500 mg/100 ml and greater produced erroneously high values for methemoglobin and total hemoglobin and "negative" values for carboxyhemoglobin. These abnormalities disappeared when the excessive lipids were removed by washing the erythrocytes in physiologic saline solution.

A 29-yr-old pregnant woman presented in her third trimester with severe pancreatitis, hyperlipidemia, and small-for-dates fetus. Studies suggested that her pancreatitis was caused by profound hypertriglyceridemia, which was the result of an underlying lipoprotein disorder exacerbated by pregnancy. Throughout the first 7 wk of hospitalization, attempts to refeed the patient with solid food and various elemental diets resulted in the induction of hypertriglyceridemia and relapses of pancreatitis. Concern for the nutritional status of the mother and the possibility of further growth retardation of the fetus prompted the use of total parenteral nutrition for the last 2 wk of gestation. This treatment was well tolerated by the mother, promptly reversed maternal weight loss, caused a rapid resolution of her pancreatitis, and did not induce further hypertriglyceridemia. This report documents that total parenteral nutrition may be safely and effectively used in the management of hyperlipidemic pancreatitis in pregnancy.

Specific physical findings are associated with the different phenotypes of hyperlipoproteinemia and may point up the need for further medical work-up to determine whether hyperlipoproteinemia is primary or secondary. The clinical manifestations of severe elevations in plasma lipid levels include xanthomas, which may be tendinous, tuberous, or eruptive. Xanthelasma is a common type of xanthoma that is seen in the creases of the eyelids. Other clinical manifestations of hyperlipoproteinemia include corneal arcus, lipemia retinalis, abdominal pain and pancreatitis. In patients with certain types of xanthoma whose serum cholesterol and triglyceride levels are normal, hyperlipoproteinemia has been diagnosed on the basis of abnormalities in plasma apoproteins and their subfractions.

Acute pancreatitis in a patient on oral contraceptive therapy is reported, and the relationship of estrogen administration to hyperlipemia and pancreatitis is discussed. A 23-year-old white woman was admitted to a hospital with epigastric pain, nausea, and vomiting. Three previous episodes of abdominal pain had been diagnosed as acute pancreatitis. On the present and previous admissions, she had just completed a cycle on her combination norethindrone 1 mg, mestranol 8 micrograms contraceptive. Laboratory results showed mild leukocytosis and elevated concentrations of blood glucose, alkaline phosphatase, serum amylase, and urine amylase. Serum cholesterol and triglycerides were elevated, and lipoprotein electrophoresis showed a type IV pattern. Abdominal sonogram revealed a normal pancreas, and all other test results were normal. The patient was treated with i.v. fluid replacement, dimenhydrinate, and meperidine hydrochloride. Within 72 hours she was asymptomatic, and serum amylase, triglyceride, and cholesterol concentrations had decreased. She was discharged with a diagnosis of acute pancreatitis secondary to oral-contraceptive-induced hyperlipidemia. Oral contraceptive therapy was not resumed. Predisposing factors, symptoms, and laboratory findings associated with estrogen-induced acute pancreatitis are presented, and the mechanisms through which serum lipid elevations and subsequent pancreatitis occur are discussed. Monitoring serum lipid concentrations before and during estrogen therapy is recommended. Research suggests that patients who are over 40 years old or have family histories of hyperlipemia are at particular risk, and that estrogen therapy should be discontinued if pancreatitis occurs.

A 17-year-old female with glycogen storage disease type I (GSD-I) died suddenly with hemorrhagic pancreatitis. She had a long-standing history of hyperlipidemia that did not respond to a regimen of frequent daytime and nocturnal intragastric feeding. Although pancreatitis is a well-known complication of hyperlipidemia, there are no reports to our knowledge of pancreatitis causing sudden death in patients with GSD-I. Pancreatitis must be added to the growing list of complications that can occur in long-term survivors with GSD-I, and should be considered when these patients present with abdominal pain.

Out of 26 patients with acute pancreatitis, 8 had several signs of bacterial infection such as high nitroblue tetrazolium (NBT) reduction of granulocytes, fever, elevated ESR and leukocytosis with granulocytosis. 2 patients had a high NBT-value without all other clinical signs of infection and 6 had such signs without a high NBT-value. --An NBT-value lower than normal was found in 6 patients, 3 of whom also had other signs of infection. The level of serum lipids, determined in only 3 of the 6, demonstrated concomitant hypertriglyceridemia. Hyperlipidemia is known to decrease granulocyte activity and might have prevented a stimulation to increased NBT-reduction otherwise brought about by bacterial infection. Further, 3 of the 6 patients with low NBT-reductions suffered from a very severe type of pancreatitis and two of them developed pneumonia. --Bacterial infection may thus contribute to a severe clinical course of pancreatitis, especially in patients with hypertriglyceridemia in whom the granulocyte function is depressed.

The clinical and epidemiological literature is reviewed as to metabolic effects of oral contraceptives (OCs). Both the estrogens and the progestins in OCs cause biochemical alterations which have metabolic consequences. Changes in glucose, lipid, and protein metabolism suggest that the dosage of both estrogens and progestins should be minimized as much as possible. All studies with OCs show no changes in glucose tolerance, but all do consistently show elevated plasma insulin levels as a result of OC usage. This occurs because the pill causes a decrease in insulin sensitivity in healthy women. Increases in age and weight, regardless of OC usage, will also cause an increase in glucose tolerance. Oral glucose tolerance deteriorates in all OC user groups, the greatest deterioration being in the high-dose estrogen users. Women with a history of gestational diabetes or impaired glucose tolerance should be considered high-risk pill users. Lipid abnormalities as a result of pill usage are primarily due to estrogen content. Fasting triglyceride levels are increased in all estrogen users. High-risk factors to be considered in OC prescription are: moderate obesity; diabetes; history of gestational diabetes; hypertension; history of pancreatitis, gallbladder or liver disease; physical evidence of xanthomatosis; age over 30 and smoker; age over 35; family history of hyperlipidemia; and family history of early atherosclerotic vascular disease. Many of the pill-induced protein synthesis changes are similar to those which occur during pregnancy. These, too, are due to estrogen content.

Chylomicrons accumulating in plasma obtained after an overnight fast are always abnormal and can be detected in association with triglyceride levels above 1000 mg per dl. The chylomicronemia syndrome is associated with marked hypertriglyceridemia (plasma triglyceride level above 2000 mg per dl), abdominal pain or pancreatitis, eruptive xanthomata, lipemia retinalis, dyspnea, mental aberrations, and other minor findings. The marked hypertriglyceridemia is usually due to the interaction of a common familial form of hypertriglyceridemia and a common acquired form of hypertriglyceridemia secondary to another disease, drug, or alcohol. Rarely, genetic abnormalities in lipoprotein lipase are the cause of the marked hypertriglyceridemia. Therapy that successfully lowers plasma triglyceride levels is associated with clearing of the symptoms and signs of the chylomicronemia syndrome and prevention of its recurrence.
