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.

It is well known that endotoxin (Et) plays an important role in severe surgical infectious diseases such as peritonitis. Recently, it has been reported that increased superoxide (O2-) formation and accelerated lipid-peroxidation cause the progress of Et shock. The present study was designed to estimate the changes in the amount of lipid-peroxides in the liver and the relationship between Et and lipid-peroxidation in bacterial peritonitis. Plasma Et levels, lipid-peroxides in the liver, the number of leukocytes in the blood and the number of bacteria in the blood and peritoneal cavity were determined using an experimental peritonitis model that was induced by intraperitoneal (i.p.) injection of E. coli, E. faecalis and B. fragilis, as well as experimental endotoxemia model induced i.p. injection of Et. The influence of ET on the function of polymorphonuclear leukocytes (PMN), that was considered to be one of the origins O2- production, was studied using PMN from the peritoneal cavity of rats. The plasma Et level was increased in an E. coli group and mixed injection group, and the lipid-peroxide levels in the liver were increased in these two groups as well as in a B. fragilis group. Plasma Et and lipid-peroxide levels in the liver were also increased in Et injected mice. In the study of the influence of Et on PMN function, O2- formation of PMN was increased when PMN was stimulated by Et with a high concentration and hexose monophosphate shunt activity was increased in all PMN stimulated by Et. These results suggest that O2- from PMN stimulated by Et is related to lipid-peroxidation in the liver, which is considered an index of injury in bacterial peritonitis.

Cefotaxime has in the past decade proved to be a most useful agent. It has established the efficacy and safety suggested in the early in vitro, pharmacological and clinical papers. It remains an excellent agent to treat many community and hospital-acquired respiratory infections, urinary tract infections, meningitis, particularly in pediatrics, spontaneous bacterial peritonitis and selected abdominal and gynecological infections.

During a 21-month period, 65 consecutive patients admitted with ascites were included in a prospective study of the incidence of spontaneous bacterial peritonitis, and paracentesis was performed on admission. The ascitic fluid was cultured, ascitic leucocytes were counted and pH was measured. Bacterial growth was found in five patients with chronic liver disease, who were diagnosed as having spontaneous bacterial peritonitis (SBP), since no intra-abdominal focus could be demonstrated. Thus, the incidence of SBP in this material was 7.7% (95% confidence limits: 2.5-17%). SBP was caused by Escherichia coli (n = 3), coagulase negative staphylococcus (n = 1), and Bacteroides species (n = 1). Abdominal tenderness, abnormal intestinal sounds, fever and hepatic encephalopathy were equally frequent in the group with SBP and in patients with sterile ascites. Infection was not anticipated in any of the patients with SBP. In contrast to several previous studies, neither ascites pH nor ascites leucocyte counts were any help in obtaining a rapid diagnosis. Survival time of patients with SBP was significantly shorter than of patients without SBP.

In an attempt to determine the optimal duration of therapy of spontaneous bacterial peritonitis, 100 patients with neutrocytic ascites and suspected spontaneous bacterial peritonitis were randomized to short-course vs. long-course treatment groups. Empiric therapy was initiated before the results of ascitic fluid culture were available. Of the 90 patients who met strict criteria for spontaneous bacterial peritonitis or culture-negative neutrocytic ascites, 43 were randomized to a group receiving 5 days and 47 to a group receiving 10 days of single-agent cefotaxime, 2 g IV every 8 hours. Infection-related mortality (0% vs. 4.3%), hospitalization mortality (32.6% vs. 42.5%), bacteriologic cure (93.1% vs. 91.2%), and recurrence of ascitic fluid infection (11.6% vs. 12.8%) were not significantly different between the 5- and 10-day treatment groups, respectively. Recurrence rates were comparable to the values reported in the literature. The cost of antibiotic and antibiotic administration were significantly lower in the short-course group. Short-course treatment of spontaneous bacterial peritonitis is as efficacious as long-course therapy and significantly less expensive.

Bacterial infection is a serious and often fatal complication of patients with liver disease and can prove fatal either directly or by precipitation of gastrointestinal bleeding, renal failure, or hepatic encephalopathy. At greatest risk are patients with alcoholic cirrhosis or decompensated chronic liver disease, or cases of acute liver disease who progress to fulminant hepatic failure or subacute hepatic necrosis. Infection appears to be unusual in patients with primary biliary cirrhosis. The site and type of infection is unrelated to the aetiology of the liver disease. Bacteraemia, pneumonia, urinary tract infection and spontaneous bacterial peritonitis are most common but infective endocarditis and meningitis, especially with pneumococci, are easily overlooked. Clinical suspicion of infection must be high as the only indication may be a general deterioration in the patients' clinical state, increasing encephalopathy or renal impairment. In the case of patients with fulminant hepatic failure, infection may precipitate the initial or recurrent encephalopathy and contributes to death in 10% of fatal cases. Spontaneous bacterial peritonitis is now recognized to occur in the absence of clinical features of peritonitis. The PMN content of the ascitic fluid may provide the only indication of infection and is the most readily available screening test. The most common types of organism responsible for all types of infection are Gram-negative enteric and streptococci, especially pneumococci, while infection with anaerobes is rare. Risk factors for infection include decompensated alcoholic liver disease, fulminant hepatic failure, gastrointestinal bleeding, invasive practical procedures and impaired host defence mechanisms against infection. Of the host defence mechanisms, impaired function of the reticuloendothelial system, complement, and PMNs represent the most common and serious defects. Defects of humoral immunity are present in ascitic fluid from patients with cirrhosis and are probably a major reason for development of spontaneous bacterial peritonitis. Diuresis improves these functions and reduces the risk of peritonitis. Treatment of infections even with the appropriate antibiotic is still associated with a high mortality but the use of adjuvant gut sterilization is promising, particularly in cases infected with Gram-negative enteric organisms. Infusions of fresh frozen plasma, blood and cryoprecipitate improve some systemic host defences and may be beneficial in the treatment and reduction of risk of infection.

A patient receiving continuous ambulatory peritoneal dialysis, and who was known to be seropositive for human immunodeficiency virus but without AIDS or ARC, had peritonitis secondary to Trichosporon beigelii. The patient had been receiving oral antibiotics and had had recurrent bouts of bacterial peritonitis. Infection was cured with removal of the peritoneal catheter and intraperitoneal and intravenous amphotericin B. The course of this episode of Trichosporon beigelii peritonitis was similar to that of peritonitis caused by other yeasts.

In a search for clinical and laboratory factors that would aid in early diagnosis of spontaneous bacterial peritonitis, we identified two groups of patients with chronic liver disease and ascites: 1) 38 patients with 40 episodes of spontaneous bacterial peritonitis, and 2) 39 randomly selected patients with 40 sterile paracenteses who were matched for severity of liver dysfunction as a reference group. A variety of clinical and laboratory features were examined. The absolute lymphocyte count in peripheral blood was lower for the spontaneous bacterial peritonitis group (mean = 703/mm3 vs. 1,212/mm3, p less than 0.005). Four ascitic fluid variables, i.e., a white blood cell count of greater than or equal to 300/mm3, a polymorphonuclear leukocyte count of greater than or equal to 240/mm3, an ascitic fluid/serum LDH ratio of greater than or equal to 0.4, or an ascitic fluid/serum glucose ratio of less than or equal to 1.0, could separate the spontaneous bacterial peritonitis and reference groups with both sensitivity and specificity of greater than 70%. Although ascitic fluid total leucocyte and polymorphonuclear leucocyte counts are appropriate indicators for the early diagnosis of spontaneous bacterial peritonitis, the possibility of their false positivity should be warranted. The use of multiple tests including ascitic fluid/serum LDH and glucose ratios has better positive predictive value than a single test alone.

Pasteurella multocida, a small, gram-negative coccobacillus , is part of the normal oral flora of many animals, including the dog and cat. P. multocida is the etiologic agent in a variety of infectious disease syndromes. We have reported 34 cases of infection caused by P. multocida and have reviewed the English literature. P. multocida infections may be divided into three broad groups: 1. Infections resulting from animal bites and scratches : The most common infections caused by P. multocida are local wound infections following animal bites or scratches . Cats are the source of infection in 60 to 80% of cases and dogs in the great majority of the remainder. Local infections are characterized by the rapid appearance of erythema, warmth, tenderness, and frequently purulent drainage. The most common local complications are abscess formation and tenosynovitis. Serious local complications include septic arthritis proximal to bites or scratches , osteomyelitis resulting from direct inoculation or extension of cellulitis, and the combination of septic arthritis and osteomyelitis, most commonly involving a finger or hand after a cat bite. 2. Isolation of P. multocida from the respiratory tract: The isolation of P. multocida from the respiratory tract must be interpreted differently than its isolation from other systemic sites. Most commonly P. multocida found in the respiratory tract is a commensal organism in patients with underlying pulmonary disease, but serious respiratory tract infections including pneumonia, empyema, and lung abscesses may develop. Most patients with respiratory tract colonization or infection have a history of animal exposure. 3. Other systemic infections: P. multocida is recognized as a pathogen in a variety of systemic infections including bacteremia, meningitis, brain abscess, spontaneous bacterial peritonitis, and intra-abdominal abscess. P. multocida often acts as an opportunistic pathogen with a predilection for causing bacteremia in patients with liver dysfunction, septic arthritis in damaged joints, meningitis in the very young or elderly, and pulmonary colonization or invasion in patients with underlying respiratory tract abnormalities.(ABSTRACT TRUNCATED AT 400 WORDS)

Spontaneous bacterial peritonitis in liver cirrhosis is due to the passage of intestinal bacteria into intestinal lymph vessels, systemic circulation and ascitic fluid. It may occur in patients with severe portal hypertension and hepatic failure, impaired reticuloendothelial phagocytic activity and low ascitic fluid opsonic activity. Spontaneous bacterial peritonitis is a monomicrobial infection usually caused by gram-negative bacteria. The treatment of choice of spontaneous bacterial peritonitis is cefotaxime. Several subgroups of cirrhotic patients have been shown to be predisposed to develop spontaneous bacterial peritonitis, including cases with gastrointestinal hemorrhage, patients with high serum bilirubin and low ascitic fluid protein concentration (< 1 g/dl), and patients who had recovered from an episode of spontaneous bacterial peritonitis. Since spontaneous bacterial peritonitis is associated with a relatively high in-hospital mortality rate (20-40%), prophylactic measures to prevent this infection are required. Short-term and long-term selective intestinal decontamination with oral norfloxacin has proved highly effective in preventing bacterial infection and spontaneous bacterial peritonitis in bleeding cirrhotic patients as well as recurrence of spontaneous bacterial peritonitis.
