During a five year period, 28 episodes of spontaneous bacterial peritonitis were documented. The number of cases recognized annually increased during the study period. Clinical and laboratory features of spontaneous bacterial peritonitis were similar to those previously reported; however, mortality was considerably lower (57 per cent). Factors associated with adverse prognosis were increasing hepatic encephalopathy, more than 85 per cent granulocytes in peripheral blood or ascitic fluid, total bilirubin greater than 8 mg/dl and serum albumin less than 2.5 g/dl. Temperature greater than 38 degrees C was associated with increased survival. Infection by enteric organisms was associated with higher mortality than infection by nonenteric organisms. Unexpectedly, patients with bacteremia fared no worse than those whose blood remained sterile. The data suggest that in patients with leukocyte counts greater than 1,000 cells/mm3 and more than 85 per cent granulocytes in their ascitic fluid, the likelihood of spontaneous bacterial peritonitis is high. Such patients deserve empiric antibiotic therapy pending the results of appropriate cultures.

In order to provide an alternative to maintenance home dialysis for patients remotely situated or who had vascular access failure, a parallel peritoneal dialysis (PD) program was developed in March 1972. Over four years, 36 patients started PD with the intention of carrying out home treatments. Thirty of the 36 succeeded and 22 completed at least six months of home treatments, seven have so far been treated for over one year. No neuropathy developed except in diabetic patients. No patient, including four who had undergone bilateral nephrectomy, was depenedent on blood transfusions. Predialysis serum creatinine values were questionably higher (p less than 0.07) in a group of six patients who at another time had been maintained on hemodialysis (HD). In this group serum albumin was (mean +/- 1 S.D.) 3.3 +/- 4 g/100 ml on PD and 3.8 g/100 ml on HD (p less than 0.05). Sixteen of the 36 patients had bacterial peritonitis on 22 occasions; the average incidence was once every 14 months of patient exposure. An epidemic of sterile peritonitis involving 40 episodes in 16 patients was resolved after machine techniques were changed. Catheter failure occurred in 15 of the 22 patients in the long-term group, but catheter replacement was not difficult.

The clinical significance and prognosis of culture-negative neutrocytic ascites in cirrhotic patients is a controversial topic. In the present study, the clinical and humoral presentation and the short- and long-term prognosis were analyzed in 36 patients with cirrhosis and culture-positive spontaneous bacterial peritonitis and in 28 patients with cirrhosis and ascitic fluid polymorphonuclear count greater than 250/mm3, a negative ascitic fluid culture, and without previous antibiotic therapy. On admission there were no significant differences between groups related to age, sex, alcoholism, fever, abdominal pain, serum albumin, serum urea, serum creatinine, Child-Pugh score, polymorphonuclear count, and total protein concentration in ascitic fluid. A greater frequency of positive blood culture was found in patients with spontaneous bacterial peritonitis (15/21 vs 2/18) (P < 0.001). Mortality during the first episode was 36% in patients with spontaneous bacterial peritonitis and 46% in patients with culture-negative neutrocytic ascites (NS). Mortality during follow-up was high and survival probability at 12 months was 32% in spontaneous bacterial peritonitis and 31% in culture-negative neutrocytic ascites. The probability of recurrence at 12 months was 33% in spontaneous bacterial peritonitis and 34% in culture-negative neutrocytic ascites. Our results show that spontaneous bacterial peritonitis and culture-negative neutrocytic ascites are variants of the same disease with a high mortality and poor prognosis.

To assess the prevalence of spontaneous bacterial peritonitis (SBP), ascitic fluid cell count, and ascitic fluid culture by conventional method and by bedside inoculation in blood culture bottles were performed in 31 consecutive patients of liver cirrhosis. Seven (22.58%) patients had ascitic fluid polymorphonuclear count (PMN) more than 500/mm. Ascitic fluid culture by conventional method was negative in all the patients, while in 4 patients culture was positive by bedside inoculation method. Six of 7 patients with SBP or its variant were in Child class C. Clinical features in these patients were abdominal pain (5 patients), fever (4) and encephalopathy (2); serum bilirubin level was 6.8 +/- 5.5 mg/dl, serum albumin 1.98 +/- 0.2 g/dl, prothrombin index 59.8 +/- 12.2%, ascitic fluid protein 0.78 +/- 0.24 g/dl. Three of 7 patients with SBP or its variant expired during hospital stay; the other 4 patients recovered after appropriate antibiotic therapy. We conclude that SBP is a serious complication in patients of liver cirrhosis with ascites. Ascitic fluid PMN count and bedside inoculation of blood culture bottles with ascitic fluid are sensitive indicators of SBP. Hence they should be performed routinely for early detection of SBP.

One hundred and thirty-four patients using continuous ambulatory peritoneal dialysis (CAPD) for a mean time of 23.1 +/- 18.3 months (range, 1-76.6) from a single center are reviewed with respect to biochemistry, hematology, parameters of dialysis efficiency, nutrition, and the nature and frequency of complications. Cumulative patient survival was 90%, 86% and 75% at 1, 2 and 3 years, and survival of patients using this technique was 75%, 62% and 40% at corresponding time intervals with no difference demonstrated in diabetic patients or in those older than 50 years. Biochemical and hematologic parameters were well maintained with peritoneal creatinine clearance increasing and peritoneal protein loss remaining stable with ongoing CAPD. Loss of ultrafiltration, however, accounted for 17.7% of permanent transfers to alternative therapy. Low serum albumin and elevated serum triglyceride concentrations correlated with mortality, whereas low serum albumin, low cholesterol, and high phosphate levels correlated with morbidity as assessed by frequency of hospital admissions. Dietary protein intake assessed by urea generation rate was significantly lower than that estimated from a 24-hour dietary recall (0.82 vs. 1.02 g/kg/day, p less than 0.01) and with the exception of body mass index and serum albumin, anthropometric and visceral protein measurements showed few correlations with nutritional adequacy. Bacterial peritonitis remained the major complication, although fungal infections made a significant contribution to morbidity and mortality. Overall, CAPD is confirmed to be a satisfactory form of dialysis for all forms of end-stage renal failure and an integral part of any renal replacement program. However, nutritional adequacy and lowering of complication rates require further investigation.

Between March 1982 and September 1983, 40 inpatients (25 men and 15 women, mean age 53 years) with alcoholic cirrhosis and total serum bilirubin greater than or equal to 5 mg per dl were studied. Those with hepatocellular carcinoma, renal failure, hyponatremia, septicemia, spontaneous bacterial peritonitis, gastrointestinal bleeding, and hepatic coma were excluded. Patients were studied for 28 days. The two groups were offered an oral diet containing 40 kcal per kg per day. Patients in the supplementary parenteral nutrition group received 40 kcal per kg per day and 200 mg nitrogen per kg per day using a central catheter. The major endpoint was total serum bilirubin on Day 28. On admission, serum bilirubin was not significantly different in the two groups: oral group, 12.5 +/- 6.6 mg per dl; supplementary parenteral nutrition group, 12.3 +/- 8.5 mg per dl. On Day 28, serum bilirubin was lower in the supplementary parenteral nutrition group (2.5 +/- 1.4 mg per dl) than in the oral group (4.1 +/- 2.2 mg per dl) (p less than 0.02). Serum bilirubin was also lower in the supplementary parenteral nutrition group than in the oral group on Days 7, 14 and 21 (p less than 0.05). Analysis of covariance, considering serum bilirubin on admission and at randomization and time between admission and randomization, confirmed these results. On Day 28, anthropometric parameters, serum transferrin, prealbumin and retinol-binding protein were higher in the supplementary parenteral nutrition group, but the differences were not significant. Serum albumin was significantly lower in the supplementary parenteral nutrition group. The incidence of encephalopathy and sepsis was not significantly different between the two groups.

DTH skin reactions can identify a population of surgical patients at increased risk for sepsis and related mortality. The usefulness of the technique is increased by repeating the test during the hospital course and by calculating a DTH score, which is the sum of the diameter of induration of all five or six tests expressed in millimeters. Regression analysis of factors that could possibly indicate development of sepsis and death after surgical treatment reveals that the most powerful predictors are serum albumin, DTH score and age of the patient. The population of patients who are anergic are more frequently malnourished than reactive patients, but the DTH response cannot be used to determine the malnourished state in individual patients. The lack of a DTH reaction (anergy) identifies an immune defect characterized by a failure of release of lymphokines in vivo. Lymphokines from normal individuals can restore to normal the absent response of anergic patients to specific antigens. In experimental animals made anergic by a heat injury, the mortality rate from bacterial peritonitis can be significantly lowered by lymphokines. Immunomodulation of demonstrated defects in host resistance is an exciting prospect for the future of surgical patients.

The reticuloendothelial system plays an important role in the prevention of bacterial infection in patients with cirrhosis. Few data are available, however, on its activity in such patients. The aim of this study was to evaluate the maximum removal capacity of hepatic reticuloendothelial system in patients with cirrhosis on the basis of study of the removal kinetics of increasing amounts of 99mTc millimicrospheres and to verify its value as a prognostic factor for death and development of spontaneous bacterial peritonitis. Common clinical and biochemical parameters, Pugh score, maximum removal capacity, aminopyrine metabolic capacity and galactose elimination capacity were measured in 43 patients with cirrhosis (33 with alcoholic cirrhosis, 8 with posthepatitic cirrhosis and 2 with cryptogenic cirrhosis). Hepatic plasma flow and indocyanine green plasma clearance were also measured in 16 of these patients. Reference range of maximum removal capacity was determined in seven normal subjects. Maximal removal capacity below the normal range was found in 24 patients (56%). In the whole series maximum removal capacity averaged 16 +/- 12 micrograms/kg body wt/min (mean +/- S.D.). Maximal removal capacity was significantly correlated with serum albumin, prothrombin index, Pugh score, aminopyrine breath test, galactose elimination capacity and indocyanine green plasma clearance but not with hepatic plasma flow. During follow-up of up to 48 mo, spontaneous bacterial peritonitis developed in six patients, all with impaired maximum uptake capacity, and 11 patients died. Survival was significantly shorter in patients with impaired maximum removal capacity than in those with normal maximum removal capacity (log-rank test: p = 0.024).(ABSTRACT TRUNCATED AT 250 WORDS)

The pathophysiology of ascites in patients with cirrhosis is complex and includes increases in hepatic sinusoidal pressure, the formation of hepatic and splanchnic lymph, renal sodium retention, and hypoalbuminemia. However, the role of hypoalbuminemia in ascites formation is controversial. Evaluating ascites in hypoalbuminemic patients with nephrotic syndrome could add to our understanding of the role of hypoalbuminemia in ascites development. We conducted a retrospective analysis of 52 adults and 21 children with nephrotic syndrome who were hospitalized in the Hadassah University Hospital on Mount Scopus during 1981-1994. There was a significant difference in the prevalence of ascites between pediatric (52%) and adult patients (23%) (p = 0.024). Pediatric patients had lower serum albumin levels than adults (1.70 +/- 0.08 g/dl vs. 2.10 +/- 0.07 g/dl, p = 0.001). Adult patients with ascites had lower serum albumin levels than adult patients without ascites (1.80 +/- 0.13 g/dl vs. 2.20 +/- 0.07 g/dl, p = 0.01). This difference was not found in pediatric patients. Temporary fluctuations in liver enzymes (up to four times the upper limit of normal for transaminases) were evident in five patients from the pediatric group with ascites, whereas all pediatric patients without ascites had completely normal liver enzymes (p = 0.035). Among the 12 adult patients with ascites, seven had liver disease (three with cirrhosis and four with amyloidosis), and two had right-sided congestive heart failure. Among the 40 adult patients without ascites, only four had liver disease (amyloidosis). The plasma albumin levels of the patients with amyloidosis without ascites were higher than patients with amyloidosis with ascites (1.90 +/- 0.10 g/dl vs. 1.50 +/- 0.07 g/dl, p = 0.03). Two patients with nephrotic syndrome and ascites (one without liver disease) had episodes of spontaneous bacterial peritonitis. Ascites in nephrotic syndrome is more common in children than in adults. Although in most pediatric patients ascites formation is probably a common manifestation of the general fluid retention, in most adult patients with nephrotic syndrome ascites can be attributed to both hypoalbuminemia and the presence of liver disease or congestive heart failure, with increased hepatic sinusoidal pressure.

The serum-ascites albumin (SAA) gradient has been defined as the serum albumin concentration minus the ascitic fluid albumin concentration. The SAA gradient is superior to the exudate-transudate concept to classify ascites, being a exact portal hypertension (PH) marker. An elevated SAA gradient (1.1 g/L or greater) correlates with PH, whereas a low gradient indicates no PH. The SAA gradient correlates well with PH in cirrhotic patients. It is also of particular utility to differentiate between congestive heart failure and malignant ascites without liver metastases (both of them with elevated ascites fluid proteins -AFP-). However, a low SAA gradient do not differentiate between tuberculous and malignant ascites. Consequently, there are still need for tests a cytology, culture for mycobacteria or ascites fluid polymorphonuclear cell count in some cases. The level of AFP, apart from the exudate-transudate concept, has some value for certain cases (a low level of AFP implicates a high risk of spontaneous bacterial peritonitis). The SAA gradient should replace the AFP concentration as the initial test to classify ascites.
