Thirty-six paired specimens of serum and ascitic fluid from 21 patients with peritonitis and ascites, most with sponetaneous bacterial peritonitis and alcoholic cirrhosis, were assayed for antibiotic content. Antibiotics assayed and number of determinations were gentamicin, 14; tobramycin, 7; ampicillin, 5; clindamycin, 3; penicillin G, 2; cephalothin, 2; chloramphenico, 2; and cefazolin, 1. In 31 pared specimens the ascitic fluid antibiotic concentration was about one half or more of the simultaneous serum level and in 17 assays exceeded 90% of the serum level. All antibiotics studied penetrated ascitic fluid equally well. Clinical response to antibiotic therapy was good in 12 of 16 patients with culture-proven bacterial peritonitis. Antibiotic levels in ascitic fluid exceeded the minimal inhibitory concentration of the infecting organisms in all but one patient who responded. Direct intraperitoneal instillation of antibiotics does not appear to be necessary routinely; however, there may be an initial lag of several hours before antibiotic concentrations is ascites achieve therapeutic levels.

Listeria monocytogenes is a Gram-positive bacillus that is pathogenic in both the normal and compromised host. We describe Listeria peritonitis and cerebritis in a patient with cirrhosis due to non-A, non-B hepatitis, and review the 11 other cases of Listeria peritonitis reported in the English-language literature. Listeria is a rare cause of peritonitis in debilitated, older patients, with two-thirds of the cases occurring in patients with chronic liver disease. Listeria peritonitis may also occur in patients undergoing peritoneal dialysis, or in those with malignancy. Peritonitis due to Listeria is clinically similar to spontaneous bacterial peritonitis, and is associated with fever, variable abdominal pain, and neutrocytic ascites; bacteremia commonly accompanies Listeria peritonitis. This syndrome can be successfully treated with antimicrobial drugs, although the third-generation cephalosporins commonly used in the therapy of spontaneous bacterial peritonitis are not recommended. Ampicillin may be the drug of choice, with combination therapy with an aminoglycoside reserved for cases that do not respond to ampicillin alone.

In a prospective, open, controlled clinical study, 190 consecutive patients who were thought to have bacterial peritonitis before operation, were randomised to antibiotic treatment during and after operation with either ceftriaxone 1 g plus metronidazole 1.5 g once daily (n = 94) or ampicillin 2 g plus netilmicin 150 mg twice daily plus metronidazole 1.5 g once daily (n = 96). Incisional and deep surgical wound infections, postoperative pneumonia and urinary tract infection as well as deaths caused by infection were recorded. Ceftriaxone-metronidazole was significantly more effective than ampicillin-netilmicin-metronidazole, 6/94 wound related infections (6%) compared to 18/96 (19%) (p = 0.02). In patients with peritonitis caused by a perforated colon or appendix the rates of clinical failure were 6% and 28%, respectively. We consider ceftriaxone plus metronidazole an efficient and easily administered antibiotic regimen in patients with bacterial peritonitis, and both the wide range of activity against Gram-negative aerobic rods and the long half life of ceftriaxone seem to be beneficial.

A 65-year-old woman on continuous ambulatory peritoneal dialysis (CAPD) developed blood-tinged dialysate and bacterial peritonitis following a colonoscopic polypectomy. She grew multiple anaerobic organisms in her dialysate despite antibiotic prophylaxis with vancomycin and gentamicin prior to the procedure. This case confirms the need for broad spectrum antibiotic prophylaxis prior to colonoscopic procedures, especially if polypectomy is planned. The antibiotic chosen should cover anaerobes as well as gram-positive and gram-negative enteric organisms. We suggest the use of ampicillin, clindamycin, and an aminoglycoside antibiotic for this prophylaxis.

The fixed combination antibiotic ampicillin/sulbactam may provide a new, safe, and effective method of treating dialysis-related bacterial peritonitis. The pharmacokinetics of this antibiotic combination were determined in patients receiving continuous ambulatory peritoneal dialysis (CAPD). The pharmacodynamic activity of this drug was also determined by use of mean bactericidal titers against selected bacterial strains. Six noninfected CAPD patients in a randomized two-way crossover study were given a fixed dose of ampicillin (2 gm) and sulbactam (1 gm) either intravenously or intraperitoneally. The mean peak ampicillin and sulbactam serum concentrations following intravenous dosing were 170.3 and 87.5 micrograms/mL, respectively. The mean peak serum concentrations of ampicillin and sulbactam following intraperitoneal dosing were 48.0 and 27.8 micrograms/mL, respectively. Absolute bioavailabilities of the intraperitoneal ampicillin and sulbactam doses were 60% and 68%. Both drugs exhibited similar distribution and elimination characteristics. Renal failure markedly reduced drug elimination. Intraperitoneal administration of ampicillin/sulbactam provided satisfactory inhibitory and bactericidal antibiotic titers for most organisms in dialysate at 6 h but not 24 h. Ampicillin/sulbactam (2 gm/1 gm) should be administered every 12 h to patients with peritoneal dialysis-related peritonitis.

We have retrospectively studied 89 episodes of spontaneous bacterial peritonitis (SBP) attended at our service with the purpose of analyzing clinical features, microbiologic data and possible etiopathogenic factors, treatment and course. The most frequent symptoms were ascites, abdominal pain and fever. Only 3.3% of episodes were asymptomatic. Twenty-four episodes (26.96%) resulted in death of the patient and only the presence of septic shock and prothrombin time lower than 35% statistically correlated with a higher mortality (100% and 53.8%, respectively, p less than 0.01) of the possible factors analyzed. The culture of ascitic fluid (AF) was positive in 52.8% of the episodes and there were no clinical or time course differences between these cases and those who presented negative culture. The isolated microorganisms were the usual ones in this condition, outstanding 37.5% of gram-positive cocci in monomicrobial SBP. Treatment was initiated within the first 12 hours from admittance in 76.4% of cases, between 12 and 72 hours in 12.3% and after 72 hours in 11.2%. Cefotaxime was given to 47.1% of episodes and 52.9% of patients received ampicillin or cefoxitin plus aminoglycoside; the mortality was lower with the first schedule (11.9% versus 40.4%, p less than 0.01).

This prospective study compared the efficacy of sulbactam/ampicillin and clindamycin/gentamicin in the treatment of children with bacterial peritonitis. Of the 29 children enrolled, 17 were evaluable; eight received sulbactam/ampicillin/gentamicin and nine clindamycin/gentamicin. Sixteen patients were previously healthy children with appendicitis. An average of 3.6 bacterial species were recovered from the peritoneal fluid of each patient. E coli and B fragilis were the most common aerobic and anaerobic isolates, recovered from 15 and ten patients, respectively. Pseudomonas aeruginosa was recovered from seven of 17 children; the three children with P aeruginosa infections randomized to the sulbactam/ampicillin group received gentamicin in addition to the investigational agents throughout the treatment course. Although the study groups were small, there was no difference in age, sex, number of pathogens per patient, duration of hospitalization, toxicity, or treatment failures between the two treatment groups or between children infected with P aeruginosa and controls. As a result of the high prevalence of P aeruginosa in the peritoneal exudate of otherwise healthy children with appendicitis, initial antimicrobial therapy in this patient population should include agents effective against this organism.

We present a 68 year old male with alcoholic cirrhosis that was admitted with abdominal pain and fever. Hepatocarcinoma and spontaneous bacterial peritonitis by Listeria monocytogenes was diagnosed. The patient was treated with ampicillin and tobramycin during 25 days following a favorable course although ascitic fluid remained abnormal during 21 days. It is noted the rarity of Listeria as a cause of bacterial peritonitis in cirrhotic patients although they are immunodeficient. It is also important to establish the etiological origin because standard treatment of spontaneous bacterial peritonitis is cefotaxime and Listeria is resistant to this antibiotic. The 66% of spontaneous bacterial peritonitis secondary to Listeria monocytogenes infection in cirrhotic patients has been reported in Spain and this might be due to a higher incidence of human listeriosis in this country.

Within a 6-year period from January 1991 to December 1996, 19 patients with Salmonella choleraesuis bacteremia were enrolled for clinical and microbiological analysis. Young children, the elderly and patients with hematological malignancy (36.8%), liver cirrhosis (26.3%), systemic lupus erythematosus (10.5%), chronic renal impairment (10.5%), and peptic ulcer (10.5%) were at high risk of this infection. The ratio of male to female was 3:1. Three cases (15.8%) were nosocomially acquired. Fever (89.5%), chills (57.9%) and anorexia (52.6%) were the most common clinical manifestations. Seven patients (36.8%) presented no gastrointestinal manifestations. Normal white blood cell count was noted in seven patients (36.8%), and neutropenia caused by underlying diseases or severe infection was found in six cases (31.6%). Various types of metastatic focal infections were found, such as septic arthritis, cutaneous infection, spontaneous bacterial peritonitis, and pneumonia. The severe immunocompromised status of patients and the high virulence of this pathogen may contribute to the high case fatality rate (21%). Higher resistance rate to commonly used antimicrobial agents was noted in ampicillin (94.7%), chloramphenicol (89.5%), and TMP/SMZ (63.8%). All strains of S. choleraesuis were susceptible to third-generation cephalosporins and fluoroquinolones. Generally, S. choleraesuis bacteremia should be taken into account in the differential diagnosis of sepsis in immunocompromised patients, even without gastrointestinal manifestations. The third-generation cephalosporins and fluoroquinolones may be the first choice for treatment of this invasive infections.

Although resistance to Listeria monocytogenes infection requires intact T-cell mediated immunity, listeriosis is an infrequent problem in patients with HIV infection and only about 50 patients have been reported to date. Only two patients with HIV and L. monocytogenes have been attended in our hospital since the beginning of aids epidemic in 1981. Case 1: a man with HIV and 364 CD4+ cells/mm3 presented fever and occipital headache. The cerebral scan was normal and L. monocytogenes grew in licuor culture. He was outcome after treatment with ampicillin and tobramycin. Case 2: a 47 years old man with HIV, 44 CD4+ cells/mm3 and hepatic virus C cirrhosis was admitted to the hospital because fever and abdominal distension. He was on menstrual pentamidine prophylaxis for Pneumocystis carinii pneumonia (PCP). Bacterial peritonitis was diagnosed and the patient begun treatment with ceftriaxone. The patient dead 72 hours later with hepatic encepholopathy. Postmortem L. monocytogenes grew. Listeriosis is an infrequent disease in patients with HIV that causes difficult diagnostic problems, principally in patients without prophylaxis with cotrimoxazole for PCP.
