Factors influencing the prognosis were studied in 165 patients with polyarteritis nodosa (PAN) and Churg-Strauss angiitis. One hundred and forty-seven of the patients fulfilled histological and/or arteriographic diagnostic criteria, and in 18 patients the diagnosis was based on clinical criteria. The patients' mean age on diagnosis was 48.4 +/- 16.4 years. The main symptoms were fever (69%), weight loss (66%), arthritis (44%), mononeuritis multiplex (67%), cutaneous signs (46%), renal involvement (26%), gastrointestinal symptoms (31%), asthma (29%), hypertension (31%) and cardiac failure (18%). Ninety-two per cent of the patients survived for at least 1 year after diagnosis of the disease, 79% for 2 years, and 63% for 5 years. The immediate causes of death were gastrointestinal bleeding or peritonitis in 11 cases, pancreatitis in two, renal insufficiency in six, cardiac failure in five, infectious complications in four, stroke in three and other causes in 11. We studied the prognosis of necrotizing angiitis in relation to clinical symptoms and laboratory findings. The association of four conditions were associated with a poor prognosis: age over 50, gastrointestinal problems, cardiomyopathy and renal signs. The survival rates in patients with these conditions were: for gastrointestinal problems, 55% 5-year survival (versus 67%); and for age over 50, 68% 3-year survival (versus 78%; p less than 0.09). One hundred and fifty-nine patients were treated with steroids for at least 18 months. Forty-eight also received cytotoxic agents (27%) and 46 plasma exchange. Patients who were treated with plasma exchange and prednisone were randomly assigned to additional treatment with cyclophosphamide. Survival rates were comparable in both groups.

The purpose of this study was to determine the incidence of death as the initial manifestation of cholelithiasis. Records of patients who died or underwent cholecystectomy for gallstone-related disease at Duke University Medical Center between 1976 and 1985 were reviewed. Thirty patients died, six of whom (20%) had previous episodes of biliary pain and stone documentation. Twenty-four (80%) were asymptomatic (three with previous incidental diagnosis of cholelithiasis). Reason for admission included acute cholecystitis (nine), pancreatitis (eight), biliary pain (six), cholangitis (four), jaundice (one), and endocarditis (one). Three patients died of gallstone complications without surgical intervention; one patient had renal failure and two had septicemia. Other causes of death were: sepsis (seven patients), cardiac failure (six), pulmonary complications (four), renal failure (three), cerebrovascular accident (three), liver failure (two), pancreatitis (one), and gastrointestinal bleeding (one). During this period, 1731 cholecystectomies were performed without mortality. In this group, the patients were younger (50 +/- 8 years vs. 64 +/- 13 years, p less than 0.001), and had a lower incidence of cirrhosis (p less than 0.001) and diabetes (p less than 0.002). The sex ratio was inverted (p less than 0.001). This study demonstrates that death from gallstones is uncommon (three cases per year), as is death from their initial clinical manifestation (1.2%). The risk of death is two- and ninefold higher in patients with acute cholecystitis or acute pancreatitis. Age, cirrhosis, and diabetes are important determinants of outcome.

Seventy-one patients with necrotizing pancreatitis in stages II and III were treated at the surgical intensive care unit in the authors' hospital, between 1982 and 1986. Pathological courses in 23 patients were so severe that a pulmonary catheter had to be applied to monitor haemodynamic changes. Seventeen of these 23 patients died (73.9 per cent), while six survived. The gravest difference between these two groups was relating to vasculopulmonary resistance, which went up strongly in the first group (428 +/- 19 dyn X sec X cm-5) and stayed moderate in the second (201 +/- 13 dyn X sec X cm-5). The left-ventricular stroke work index in the first group was lower with significance than that in the second, the values being 33.4 +/- 2 g X m/m2 versus 44 +/- 4.6 g X m/m2.

Acute pancreatitis is often associated with impaired cardiovascular function. This study examined the systemic cardiovascular effect of acute pancreatitis induced by injection of autologous bile (0.5 ml/kg) into the canine pancreatic duct. After acute pancreatitis was induced, eight dogs were given no resuscitation (group 1, untreated pancreatitis), and lactated Ringer's solution was infused in 11 dogs (group II, treated pancreatitis) to maintain mean arterial pressure and pulmonary wedge pressure at control values. In the untreated pancreatitis group, mean arterial pressure, cardiac output, stroke volume, and stroke work values decreased (mean arterial pressure from 101 +/- 4 to 74 +/- 12 mm Hg, cardiac output from 118 +/- 7 to 56.2 +/- 1.1 ml/min/kg; stroke volume from 0.93 +/- 0.08 to 0.22 +/- 0.07 ml/beat/kg; p less than 0.05), whereas heart rate and peripheral resistance increased (heart rate from 125 +/- 7 to 185 +/- 10 beats/min, peripheral vascular resistance from 3130 +/- 410 to 4436 +/- 610 dynes/sec/cm5; p less than 0.05). Although coronary blood flow, endocardial-epicardial flow ratio, and myocardial oxygen delivery values decreased progressively in group I after induction of pancreatitis, these changes did not achieve statistical significance. All indices of cardiovascular function and coronary blood flow remained unchanged in group II. Neither dP/dt max, the maximal rate of left ventricular pressure increase, nor dP/dt at a developed pressure of 40 mm Hg (an index of myocardial contractility minimally affected by changes in preload and afterload) were depressed by bile-induced acute canine pancreatitis in either group. Our data indicate that the detrimental effects of acute pancreatitis on cardiovascular function are related solely to hypovolemia and reduced cardiac filling and not to humoral or reflex effects induced by the disease.

Emergency surgery is the only effective treatment of ruptured abdominal aortic aneurysms, even though morbidity and mortality rates remain high. We have studied the feasibility of left retroperitoneal aortic exposure in these cases in an effort to reduce postoperative complications. Over a 33 month period, 29 patients underwent emergency surgery for either a ruptured or symptomatic infrarenal abdominal aortic aneurysm. Of 13 patients with ruptured aneurysms, 4 underwent repair through a midline transperitoneal approach (3 deaths) whereas the remaining 9 were repaired through the retroperitoneal exposure (1 death). Supraceliac aortic clamping through the same incision prior to aneurysm exposure maintained hemodynamic integrity. The remaining 16 patients with symptomatic aneurysms were all treated through the retroperitoneal exposure (3 deaths). In the retroperitoneal groups, the cause of death was cardiac in two patients, hypertensive stroke in one, and necrotizing pancreatitis in one. Morbidity consisted of prolonged intubation, respiratory distress syndrome, and thrombophlebitis in one patient each and acute tubular necrosis in two patients. We believe that the left retroperitoneal approach is a useful option in the emergent treatment of abdominal aortic aneurysms.

Left ventricular contractility following induction of experimental pancreatitis (EP) was studied. Contractility was evaluated by analyzing the left ventricular end systolic pressure-diameter relationship (sigma ES). Sigma ES is independent of large changes in preload, afterload, and heart rate, but sensitive to changes in ventricular contractility. Following injection of 100,000 IU trypsin in 4% taurocholate into the pancreas to induce EP, seven of eight dogs survived 5 hr. These dogs exhibited an initial significant reduction in mean arterial pressure (MABP) which stabilized at 90% of control at 3-5 hr post-EP. Cardiac output (CO) dropped slowly after EP induction (from 3.08 +/- 0.43 to 2.22 +/- 0.22 liters/min) associated with no significant change in peripheral resistance. Stroke work and stroke volume were markedly depressed reflecting the changes in MABP and CO. No consistent changes in +dP/dt or -dP/dt were observed. The ratio of endo/epicardial blood flow was unchanged as was blood Ca2+ levels throughout the experiment. Ventricular contractility as reflected by sigma ES tended to improve (from 49.7 to 69.6 mm Hg/mm at 4 hr following EP). Therefore, it was concluded that these animals exhibited no loss of ventricular contractility during EP.

Plasma fibronectin concentrations were significantly (P less than 0.001) below the reference range in dogs with disseminated intravascular coagulation (DIC) secondary to nonlymphomatous neoplasia, acute necrotizing pancreatitis, sepsis, chronic active hepatitis, and heat stroke. There was no statistical evidence of a group effect. Decrease in fibronectin concentration was associated with severe DIC, although no attempt was made to correlate fibronectin concentration with prognosis. These findings parallel those reported for severely ill human beings with diseases associated with DIC. They exemplify the potential of spontaneous diseases in animals as models for the study of human disease.

We attempted to modulate several determinants of the host immunologic profile to improve kidney transplant survival: (1) genotype matching of the cadaver donor with the recipient, (2) assessment in recipients of living related donors (LRD) for predisposition to generate suppressor cells in mixed lymphocyte culture (MLC), (3) pretransplant splenectomy and transfusions, and (4) posttransplant immunologic monitoring. Between January, 1979, and July, 1980, 48 primary renal transplants were performed and followed up between 6 and 24 months. Pretransplant splenectomy was performed, and transfusions were administered in 38 of 48 and 48 of 48 patients, respectively. Donors and recipients of 10 of 11 cadaveric transplants were genotyped and selected for one HLA haplotype identity. All 10 proved to also be one DR antigen matches. There were no cadaveric kidney losses, but one surgical antibody to T cell subtest were used to modulate rejection therapy. The LRD group (n = 37) included 13 HLA-identical, seven haploidentical low MLC reactors, and 17 haploidentical high MLC reactors. Three deaths occurred (diabetes and myocardial infarction, stroke, and pancreatitis). A three-component coculture assay was used in the LRD group before transplantation to determine the capacity to generate specific and nonspecific MLC suppressor cells. Suppressor cells were seen in 17 patients given standard immunosuppression postoperatively without rejection episodes. However, in 20 patients incapable of generating suppressor cells, seven biopsy-proved rejection episodes occurred. There were no kidney losses, with 44 of 48 surviving recipients demonstrating normal renal function.

Fifteen patients with severe pancreatitis underwent cardiovascular monitoring in an intensive care unit. The principal findings were a high cardiac index and a decrease in systemic vascular resistance. A significant negative correlation was found to exist between these two parameters (p less than 0.001). Severe pancreatitis apparently results in hemodynamic changes similar to those observed in sepsis. The mechanisms responsible for these observations are not known, although circulating vasoactive compounds resulting from pancreatic necrosis remain a strong possibility. Despite demonstrating a significant decrease in left ventricular stroke work index and an abnormal elevation in pulmonary capillary wedge pressure, the existence of a myocardial depressant factor could not be conclusively proved from these data.

An analysis was made of 41 cases of disseminated intravascular coagulation in dogs, with the objective of evaluating routine and nonroutine laboratory tests used in making the diagnosis. The dogs were grouped on the basis of underlying disease, which included neoplasia (39%), pancreatitis (30%), chronic active hepatitis (15%), heat stroke (12%), and sepsis (4%). Of the diagnostic tests evaluated, those for determination of activated partial thromboplastin time, antithrombin III activity, prothrombin time, and the platelet count were the most valuable. Of the clotting factors, factor V activity was decreased more frequently than the activity of factor VIII:C (factor VIII: procoagulant). The factor VIII:C activity was in conflict with prevailing dogma that reflects depression of this factor in disseminated intravascular coagulation. Factor VIII:C activity was decreased in only 29% of dogs studied. Activation of the fibrinolytic system was manifested by decreased plasminogen activity in 49% of the dogs studied. Sixty-one percent of the dogs had increased amounts of fibrin (ogen) degradation products.
