In a prospective study abdominal paracentesis with ascitic fluid aspiration was performed in 54 consecutive patients with ascites of unknown cause. The ascitic fluid was examined cytologically and bacteriologically. The total cholesterol concentration was measured with an enzymatic colorimetric method. Malignant disease was diagnosed in 34 patients. Two of them had both malignant disease and liver cirrhosis and were excluded. Seventeen patients had liver cirrhosis, one had acute pancreatitis, and two had decompensated heart disease. The diagnostic value of an ascitic cholesterol concentration greater than 1.2 mmol/l in terms of predicting malignant disease was 87.5% (95% confidence limits, 71.0-96.5). The predictive value of an ascitic cholesterol concentration less than or equal to 1.2 mmol/l in terms of benign disease was 80.0% (95% confidence limits, 56.3-94.3). It is concluded that ascitic cholesterol measurement is a valuable supplement to cytologic examination in distinguishing between ascites of malignant and benign origin.

Serum IgA, IgG and IgM values in 238 normal aged subjects were compared with those in 100 normal adults. Both male and female aged subjects displayed a significant rise in IgA and a significant fall in IgM, whereas IgG values were not markedly different. It was found that IgA increased and IgM decrease by an average of 12 mg % and 10 mg % (17 mg % in the aged) per decade respectively. Values were also determines in 597 aged hospital patients and related to the disease for which they were admitted. Increases in all three Igs were noted in sclerotic cardiopathy, chronic cerebrovascular insufficiency, acute broncopneumopathy (IgA increase only in chronic forms), and gastroduodenal ulcer. Diverticulosis of the colon and acute pancreatitis, however, were accompanied by elevated IgA values only. Increases were particularly marked in chronic liver disease, less so in diseases of the gallbladder. Neoplasia was usually accompanied by higher Ig levels.

It has been reported that electrocardiographic abnormalities may be associated with acute pancreatitis. However, the data are lacking or sketchy. The aim of this study was to assess the frequency and type of electrocardiographic abnormalities present in patients with acute pancreatitis. Fifty-six consecutive patients with acute pancreatitis and without previous history of heart disease were studied. Eleven patients had arterial hypertension. Forty-one patients had mild pancreatitis and 15 had the severe form of the disease. On admission, all patients underwent a standard 12-leads electrocardiogram and a serum electrolyte determination. Nineteen healthy subjects were also studied as controls. Twenty-seven patients (48.2%) (10 with severe pancreatitis and 17 with mild pancreatitis) had a normal electrocardiogram. In the remaining 29 patients (51.8%), one patient with severe pancreatitis had atrial extrasystoles and eight had bradycardia (less than 60 beats/minute) (two with severe pancreatitis and six with mild pancreatitis); 14 patients had changes of the T-wave and/or the ST-segment (two with severe pancreatitis and 12 with mild pancreatitis); seven patients showed disturbances of the intraventricular conduction (one with severe pancreatitis and six with mild pancreatitis): four had left anterior hemiblock, two had complete left bundle branch block and one had left anterior hemiblock and incomplete right bundle branch block; one patient with mild pancreatitis had atrioventricular block (first degree). No differences in heart rate, RR interval, PR interval and QT interval were found when patients with acute pancreatitis were compared with healthy subjects, nor when patients with severe pancreatitis were compared with those having the mild form of the disease. Seventeen of the 29 patients with electrocardiographic abnormalities (52.6%) also had serum electrolyte alterations. More than 50% of the patients with acute pancreatitis had electrocardiographic abnormalities and electrolyte alterations were also present in about one-half of these.

From January 1988 through October 1997, 167 cardiac transplants were performed. 1246 endomyocardial biopsies (EMBs) from 138 cardiac allograft recipients were investigated and graded according to the Working Formulation (WF) criteria. The specimens were inadequate in 44 EMBs (3.5%), while 598 (48%) showed no rejection. The grade of rejection was: mild (grade 1A and 1B) in 531 EMBs (42.6%), mild/moderate (grade 2) in 38 (3.1%), and moderate (grade 3A and 3B) in 35 (2.8%). The indications for transplantation were: dilated cardiomyopathy (46.1%); ischemic disease (37.1%); valvular disease (12%); hypertrophic cardiomyopathy (1.8%); myocarditis (1.2%); congenital cardiopathy (0.6%), restrictive cardiomyopathy (0.6%) and chronic rejection (0.6%). The most reliable histologic feature of acute rejection was the myocyte necrosis or damage in presence of pironinophilic mononuclear cell infiltrate, so our protocol requires multifocal or diffuse myocyte damage (rejection grade 3A and 3B) to perform an additional treatment, which was required in 35 cases (2.8%). An intermediate grade mild/moderate 2, was introduced from the WF to classify the EMBs in which the myocyte necrosis was scant or not clear; this grade in our series generally resolves without any additional treatment; in order to monitor the rejection another EMB was performed 5 days after in these patients. The EMBs showed also the following lesions other than acute rejection: Quilty A (79 patients; 57.25%), Quilty B (24 pts; 17.39%), early ischemic necrosis (43 pts; 31.15%) and late ischemic necrosis (5 pz; 3.62%). Quilty B and late ischemic necrosis were correlated with acute rejection (grade 2), furthermore the patients with graft vascular disease showed 3 or more episodes of acute rejection. These findings confirm the relationship between acute and chronic rejection. Furthermore, a relationship between chronic rejection (4 pts) and infection from hepatitis C (antibodies positive 3 pts/4) and cytomegalovirus (antibodies positive 4 pts/4) was found in our series. In the follow-up period (117 months), a 30.72% death rate was recorded; the main causes of death were: early failure of the transplanted heart (30 pts) in 4 of them associated with pulmonary hypertension, infections (6 pts), sudden death (4 pts), graft's vasculopathy (4 pts), acute pancreatitis (1 pts) pulmonary embolism (1 pts), lung (1 pts) and ovary (1 pts) carcinoma, acute rejection (1 pts), others (2 pts). In the early period (< 1 month), the most frequent cause of death was the early failure of the transplanted heart, while in the late period (> 1 year) the chronic rejection following by sudden death and tumours. The actuarial survival curve drops to 83.13% after the first post-operative month, abates to 75.30 at the end of the first year, and progressively decreases to 70.48% at the end of the fifth follow-up year. The mortality rate was 38.7% in pts transplanted for ischemic disease and 24.7% for dilated cardiomyopathy. Cardioplegia seems to play an important role in the success of the heart transplant.

The group B coxsackieviruses (CVB) induce experimental pancreatitis and myocarditis in mice and are established agents of human myocarditis, especially in children. We tested the hypothesis that the development of CVB-induced myocarditis is linked to CVB-induced pancreatitis by studying the replication of different CVB strains in mice. Eight of nine genotypically different type 3 CVB (CVB3) strains induced acute pancreatitis in mice; of these, three viruses also induced acute myocarditis. One CVB3 strain was avirulent for both organs. Myocarditis was not observed in the absence of pancreatitis. The results obtained by inoculation of mice with strains of other CVB serotypes were consistent with these data. Infectious virus titers were measured in serum, pancreas, and heart as a function of time after inoculation of mice with three CVB3 strains. Each strain was representative of one of the three viral virulence phenotypes: avirulent, pancreovirulent only, and cardiovirulent. All strains replicated well and persisted in the pancreas through 8 days post-inoculation, but the cardiovirulent CVB3 strain tended to replicate to higher titer earlier and persist longer in sera, pancreatic, and cardiac tissues than the noncardiovirulent strains. Replication of the CVB3 strains were studied in two human pancreatic tumor lines and in primary human endothelial cell cultures derived from cardiac artery. Cardiovirulent strains, both individually and as a group, tended to replicate to titers as high as, or higher than, noncardiovirulent strains did in cell culture. The data are consistent with the possibility of an etiologic link between CVB-induced pancreatic and heart disease.

We report a case of a patient with acute pancreatitis who developed serious heart rhythm abnormalities on three occasions, two of which were associated with administration of the first generation antihistamine chloropyramine, and the third one with hypomagnesemia and hypokalemia. Dysrhythmic events consisted of bigeminy, multifocal ventricular extrasystoles and torsades de pointes-like ventricular tachycardia. Electrocardiographic changes in acute pancreatitis in the absence of previous heart disease can occur in more than half of the cases. Antihistamines are medications that are known to produce heart rhythm disturbances, especially the second generation drugs astemizole and terfenadine. This is the first report of chloropyramine causing dysrhythmia. It seems that acute pancreatitis patients are especially prone to heart dysrhythmia caused by different factors such as electrolyte disturbances and pronounced vagal tone. Acute pancreatitis may be added to the list of risk factors with altered 'repolarization reserve', predisposing to drug-induced QT interval prolongation and possible torsades de pointes occurrence.

Metformin is a common medication used for the treatment of type 2 diabetes, especially in obese subjects. Clinical studies show that, in addition to the lowering effect of blood glucose, metformin reduces cardiovascular risk, does not induce weight gain and additionally, provides a unique safety strategy and efficacy in patients with diabetes and heart disease. However, this treatment is not without risks. The most feared metabolic complication is lactic acidosis that often occurs with complex and severe clinical symptoms and is associated with a high mortality risk. We detail our experience, during one year, regarding four patients with diabetes treated with metformin who developed such acute renal failure and lactic acidosis as to require hemodialysis treatment. The patients selected had previous normal renal function but a history of serious cardiovascular disease (hypertensive cardiomiopathy, ischemic revascularized and/or dilated, chronic obstructive arterial disease). We observed in all four of our patients an onset of non-related symptoms (fever, fatigue, vomiting and gastrointestinal disorders), a rapid deterioration in renal function, anuria and very high levels of lactic acid. In two patients we found acute pancreatitis. In addition to rehydration therapy, hemodialysis was started instantly with progressive rebalancing of the biohumoral status, effective recovery of spontaneous diuresis and improvement of the clinical status in three patients. Unfortunately, we had a failure during the initial hours of ward admittance, with an important clinical situation complicated by acute cardiac ischemia, abnormal heart rhythm, ending in death. Our experience provides us with elements to reflect on. Lactic acidosis is a serious metabolic disorder because it is associated with a high mortality risk. So a rapid diagnosis and a complete recognition of all the fundamental elements are important for its management. Starting hemodialysis early and prolonged treatment can solve complicated clinical status, correct acidosis and restore kidney function in patients with serious comorbidity.
