Twenty nine patients of an intensive care unit (9 women and 20 men), aged 63.9 +/- 15.8 years, with a mean body weight of 62.5 +/- 11.8 kg were treated during 9.4 +/- 2.1 days by aztreonam (2 x 1 g/24 h) administered by short infusion (30 min) for a severe infection due to a Gram-negative bacilli. The primary (n = 25) or nosocomial (n = 4) infection sites were a peritonitis (14), a septicaemia (6), a cholecystitis (6), a pyelonephritis (5), a cholangitis (2), a subphrenic abscess (1) or a pneumonia (2). The isolated Gram-negative bacilli were all susceptible to aztreonam, their MIC being less than or equal to 0.5 micrograms/ml, except for a Pseudomonas aeruginosa (MIC = 4 micrograms/ml). Aztreonam was administered as a single therapy to 7 patients and in association with metronidazole (18) and/or penicillin G (14) to 22 patients; in fact, anaerobes were isolated in ten patients. The mean serum concentrations of aztreonam, as measured by HPLC, before and after the 7th administration respectively were 83.2 +/- 17.5 and 6.1 +/- 5.5 micrograms/ml for peak and through levels. The treatment of the 29 infections was a success in all the cases. No complication occurred due to the presence of Gram positive cocci (n = 4) in the first bacteriological sample, or due to the emergence (n = 12) of Gram positive cocci, except for one case of sepsis of the abdominal wall by Staphylococcus aureus. Aztreonam (2 x 1 g/24 h) may be a suitable alternative for the treatment of severe infections of intensive care units, mostly due to Gram-negative bacilli.

Laboratory and clinical comparative investigations with cefotiam (CTM) and cefazolin (CEZ) were performed to confirm efficacy and safety in surgical, biliary tract infections. The following results were obtained. 1) The MICs of CTM against organisms, 20 strains, which were isolated from bile of patients with cholecystitis, were studied, especially those of CTM against E. coli and Klebsiella were 0.2 - greater than or equal to 100 micrograms/ml and 0.1--12.5 micrograms/ml, respectively, considerably lower than those of CEZ. And moreover against CEZ-resistant Proteus morganii and Serratia marcescens, CTM showed potent activities, that is, MIC values, 12.5--50 micrograms/ml and 0.78 microgram/ml, respectively. 2) In cholecystectomized patients, 2 grams of CTM was injected intravenously, followed by determination of bile concentration in gallbladder, common bile duct and concentration of gallbladder and liver tissue about 2 hours after administration. The mean bile concentrations of CTM in gallbladder and common bile duct were 1,213.2 micrograms/ml and 1,287.8 micrograms/ml, respectively. The peak concentration of CTM was 2,919.0 micrograms/ml. The mean concentrations of CTM in gallbladder and liver tissue were 28.5 micrograms/g and 45.7 micrograms/g, respectively. On the other hand, the mean bile concentrations of CEZ in gallbladder and common bile duct were 138.7 micrograms/ml and 128.8 micrograms/ml, respectively. 3) Bile concentrations of CTM was compared with those of CEZ by crossover method. The concentration of CTM was 37.7 micrograms/ml even at 5 or 6 hours after 2 grams intravenously administration. CTM showed extremely higher concentration than CEZ in bile. 4) The clinical effect was studied in 6 cases of surgical, biliary tract infections. The results were excellent in 2 cases, good in 3 cases and poor in 1 case, and the clinical efficacy was 83%. 5) CTM was administered to 6 patients who showed negative to intracutaneous reaction test. Nausea, itching, and eruption were observed in each 1 case after intravenously administration of CTM 2 g, however these adverse reactions disappeared within several hours. Throughout the course of treatment, any unusual laboratory findings related to CTM were not observed.

A new antibiotic drug of cephalosporin, with marked resistance to beta-lactamase, cefmenoxime (CMX) for parenteral use was used in 14 patients with acute or subacute cholecystitis and cholangitis. CMX was given by intramuscular or intravenous drip infusion at a daily dose of 500 mg to 2 g. Clinical response was excellent in 3 cases, good in 10 cases, fair in 1 case and poor in none. Any clinical adverse effect was not recognized. CMX in a dose of 500 mg was given by intramuscular administration before the operation to 8 patients, and in 7 cases CMX in a dose of 1 g was given by intravenous administration before or during the operation. Tissue specimens of different sites were taken from the removed organs. The materials of A-bile and B-bile were subsequently taken at intervals. CMX concentrations in the A-bile increased after intramuscular injection and reached to peak 2 hours, then declined very slowly. CMX concentrations in the A-bile after intravenous administration reached to peak at 1 hour, then declined very slowly, too. CMX concentration in the B-bile reached to high level of the concentration comparative quickly after intramuscular and intravenous administration, and it was thought to be excreted through the gallbladder wall. CMX concentration in the gallbladder wall was directly proportional to the degree of pathological changes of the inflammation. On the CMX concentration in patients with cholecystitis and cholangitis, the concentration in A-bile, B-bile and gallbladder wall were observed higher than the MIC of CMX for pathogenic Gram-negative bacilli. CMX therefore will be a very useful drug when used for chemotherapy of the infectious diseases of the biliary tract.

An antibiotic drug of aminoglycoside group, amikacin (AMK) for parenteral use was used to 8 hospitalized patients: 4 with acute or subacute cholecystitis and cholangitis, 4 with acute peritonitis (3 cases were due to acute appendicitis and a case was torsion of right ovarian cyst). AMK in a dose of 200 mg were administered by intravenous drip infusion for 1 to 2 hours, twice a day for 4 to 9 days. To the cases with biliary tract infection, AMK was treated to preoperatively and to the cases with acute peritonitis, AMK was treated to the postoperatively. Clinical response was excellent in 2 cases, good in 6 cases, fair and poor in none. No adverse effect was observed. The organisms were isolated in 4 cases, 4 were Escherichia coli, 1 was Klebsiella pneumoniae and 1 was Bacteroides fragilis. The MIC for AMK were 3.13-1.56 micrograms/ml in 10(8) and 10(6) cells/ml, except Bacteroides fragilis. Before the operation of above cases, AMK in a dose of 200 mg were administered by intravenous drip infusion in 2 cases (acute and subacute cholecystitis and cholangitis with cholelithiasis), 5 cases by intramuscularly and 1 case by intravenously (acute appendicitis with localized peritonitis). The materials of A-bile, B-bile, wall of gallbladder, the appendix, ascites and serum samples were taken during the operation. AMK concentration was measured by bioassay method with Bacillus subtilis ATCC 6633 as test organism. AMK concentration in B-bile were higher than those in the A-bile. AMK concentrations in wall of gallbladder were much higher than those in A and B-bile. The concentrations after intravenous drip infusion were higher than those after intramuscularly administration. AMK changes of inflammation. In a case of gastric ulcer, AMK 200 mg by intravenous drip infusion was administrated, the AMK concentrations of the tissues at 25 minutes after end of infusion, they were 15.00 micrograms/g in gastric ulcer, 7.20 micrograms/g in normal gastric wall, 9.14 micrograms/g in duodenal wall and 8.12 micrograms/g in the omentum, respectively. Serum concentration of AMK on this case at 58 minutes was 15.7 micrograms/ml. Therefore, it was supposed that AMK could be used safety and effective by intravenous drip infusion.

We studied the in vitro activity of cefminox (MIC by agar dilution) and cefoxitin against 477 facultative Gram-positive and Gram-negative isolates which were recovered from clinical specimens and identified by standard methods. Cefminox has proved to be 4-16 times more active than cefoxitin against enteric Gram-negative bacilli commonly involved in cholecystitis, secondary peritonitis, intraabdominal abscesses and gynecological infections. On the contrary, cefoxitin has proved to be four times more active against Gram-positive cocci. Both have been ineffective against Enterobacter spp., Pseudomonas aeruginosa and Acinetobacter spp. The microbiological activity and pharmacokinetic parameters of cefminox make it one of the first choice treatments for community-acquired intraabdominal and pelvic infections with the presence of anaerobes.

Patients with intra-abdominal infections differ with regard to the type of infection and the severity of illness. However, the impact of these factors, together with differences in drug exposure, on clinical response is not well understood. Using phase 2 and 3 data for patients with complicated intra-abdominal infections, the relative importance of tigecycline exposure, host factors, and disease factors, alone or in combination, for the probability of clinical response was examined. Patients with complicated intra-abdominal infections who received tigecycline intravenously as a 100-mg loading dose followed by 50 mg every 12 h for 5 to 14 days and who had adequate clinical, pharmacokinetic, and response data were evaluated. Multivariable logistic regression was used to identify factors associated with clinical response. A final multivariable logistic regression model demonstrated six factors based on 123 patients to be predictive of clinical success: a weight of <94 kg (P = 0.026), the absence of Pseudomonas aeruginosa in baseline cultures (P = 0.021), an APACHE II score of <13 (P = 0.029), non-Hispanic race (P = 0.005), complicated appendicitis or cholecystitis (P = 0.004), and a ratio of the area under the concentration-time curve (AUC) to the MIC (AUC/MIC ratio) of > or =3.1 (P = 0.003). The average model-predicted probability of clinical success when one unfavorable factor was present was 0.940. This probability was lower (0.855) when the AUC/MIC ratio was < 3.1 and the remaining five factors were set to the favorable condition. The average model-predicted probability of clinical success in the presence of two unfavorable factors was 0.594. These findings demonstrated the impact of individual and multiple factors on clinical response in the context of drug exposure.

A 72-year-old man, receiving 8 mg daptomycin/kg body weight/day for methicillin-resistant Staphylococcus aureus (MRSA) bacteremia, was diagnosed with MRSA/vancomycin-resistant Enterococcus faecium (VRE) cholecystitis (daptomycin MIC values, 1 and 2 mg/liter, respectively). After the fifth drug dose, the bile concentration of daptomycin was 66 mg/liter 5 min after drug administration, with the biliary concentration/MIC values higher than 30 for both bacterial strains. Therefore, daptomycin achieved therapeutic levels in bile, hence suggesting a role for the drug in the treatment of MRSA/VRE cholecystitis.

The efficacy of 200mg oral ofloxacin given twice daily for 3 days was evaluated in 98 hospitalized cases with acute diarrhea or dysentery. Sixty cases were female, most of whom were laborers.Vibrio cholerae, Vibrio parahaemolyticus, Shigella flexneri, Shigella boydii, Shigella sonnei, Aeromonas hydrophila, Aeromonas spp., and Plesiomonas shigelloides were isolated from fecal samples in 36 of 86 cases (42%) with diarrhea and 5 of 12 cases (46%) with dysentery.E. coli agglutinated with various E. coli polyvalent antisera were found in another 25 cases (26%). With the exception of E. coli, most of the clinical isolates were highly susceptible to ofloxacin and norfloxacin with minimal inhibitory concentrations (MIC90) of 0.047-0.38 and 0.016-0.25mg/L, respectively. A total cure was achieved in 96.5% of cases with diarrhea and in 100% of cases with dysentery. There was a delayed response in two cases and only one case clinically failed to respond.V. cholerae was repeatedly isolated on day 3 in another case who had recovered on day 2, and 1 case developed gangrenous cholecystitis and ischemic enteropathy after an initial response to ofloxacin.
