The reticuloendothelial system phagocytic activity, estimated by the plasma elimination rate constant of 99mtechnetium-sulfur colloid, was studied in 41 decompensated cirrhotics and 10 normal subjects. The results were related to the incidence and type of bacterial infections occurring during hospitalization and follow-up, and to survival. The elimination rate constant of 99mtechnetium-sulfur colloid was lower in cirrhotic patients (0.168 +/- 0.007) (means +/- S.E.) than in normal subjects (0.220 +/- 0.005) (p less than 0.01). Cirrhotics were divided into two groups. Group I (16 patients) and Group II (25 patients) had normal or reduced elimination rate constant of 99mtechnetium-sulfur colloid, respectively. Both groups were similar in relation to clinical and biochemical data, hepatic blood flow, and wedged hepatic venous pressure. However, the liver scan and the elimination rate constant of indocyanine green were more altered in Group II. Patients in Group II developed acute bacterial infections more frequently than did patients in Group I. During hospitalization (24 +/- 2 days), bacteremia occurred in six patients in Group II and in none in Group I (p less than 0.05). During follow-up (28 +/- 3 months), 5 patients in Group II and none in Group I developed bacteremia (p less than 0.05). The cumulative survival rate of Group I patients was higher (p less than 0.05) than that of Group II patients at 3 months (100 vs. 80%), 6 months (94 vs. 68%), 24 months (74 vs. 42%), and 48 months (68 vs. 34%). We suggest that decompensated cirrhotics with depressed reticuloendothelial system phagocytic activity are at great risk to acquire bacteremia, and that reticuloendothelial system phagocytic activity has prognostic value in cirrhosis.

To investigate if oral, nonabsorbable antibiotics prevent bacterial infections in cirrhotics with gastrointestinal hemorrhage, 140 consecutive patients were randomly allocated into two groups: 68 patients (Group I) were given oral, non absorbable antibiotics (gentamicin + vancomycin + nystatin or neomycin + colistin + nystatin) from the inclusion into the trial up to 48 hr after cessation of the hemorrhage, or until emergency surgery or death in those cases who continued bleeding; and 72 patients (Group II) did not receive oral, nonabsorbable antibiotics. Both groups were similar in relation to clinical and laboratory data and characteristics of the hemorrhage. The incidence of infection was significantly lower in Group I than in Group II (11 patients in Group I and 25 in Group II developed proved infections; p less than 0.025). This difference was due to the fact that spontaneous bacteremia and peritonitis and urinary tract infection caused by enteric bacteria occurred almost exclusively in Group II. Two patients of Group I and 10 of Group II developed spontaneous bacteremia and/or peritonitis caused by enteric bacteria (p less than 0.025). These results indicate that prophylactic administration of oral, nonabsorbable antibiotics markedly reduces the incidence of infections caused by enteric bacteria in cirrhotic patients with gastrointestinal hemorrhage.

Concomitant therapy led to a non-statistically significant advantage (5%) over sequential therapy, coming closer to 90% cure rates. Both therapies showed an acceptable safety profile. ClincialTrials.gov: NCT01273441.
