Clinical evaluation, safety and kinetics in serum of sulbactam/cefoperazone (SBT/
CPZ
) in patients with lower respiratory tract infections have been studied in a multicenter trial participated by 28 institutions in Kyushu area during a period of 13 months from March 1987 to March 1988. 1. Mean peak serum levels of SBT and
CPZ
in 35 patients up to 4 hours after intravenous infusion of 2 g of SBT/
CPZ
were 38.2 +/- 17.3 micrograms/ml for SBT and 104.3 +/- 31.4 micrograms/ml for
CPZ
. Serum half-lives of SBT and
CPZ
were 0.76 hour and 1.53 hours, respectively. These results were in similar ranges to those reported elsewhere for SBT/
CPZ
. 2. Serum half-lives of SBT and
CPZ
after intravenous infusion of 2 g of SBT/
CPZ
were not significantly prolonged in patients with moderate liver or kidney dysfunctions. 3. Clinical efficacy rates of SBT/
CPZ
in 217 patients were 93.1% (81/87) for pneumonia, 93.3% (14/15) for lung abscess, 78.9% (15/19) for acute exacerbation of chronic bronchitis, 57.1% (4/7) for diffuse panbronchiolitis, 72.4% (21/29), 74.4% (32/43) and 100% (9/9) for infections concurrent to bronchiectasis, chronic respiratory disease and pulmonary emphysema, respectively. Those were 50% (1/2) for bronchitis associated with lung cancer and 66.7% (4/6) for empyema. The overall efficacy rate was 83.4% (181/217). 4. Clinical efficacy rate of SBT/
CPZ
for pneumonia in patients with underlying diseases such as lung cancer, pulmonary tuberculosis and pneumoconiosis, etc, was 85.3% (29/34) and was not significantly different from the efficacy rate of 98.1% (52/53) in patients without these underlying diseases. 5. Of 30 patients who failed to respond of previous antibiotic treatments, 21 were effectively treated by SBT/
CPZ
. 6. Bacteriological eradication rates against Pseudomonas aeruginosa,
Haemophilus
influenzae and Streptococcus pneumoniae were 42.9% (9/21), 87.5% (14/16) and 100% (5/5), respectively. The overall eradication rate in all cases including polymicrobial infections was 72.8% (67/92). 7. The high levels of peak serum concentration of
CPZ
, and the difference between serum levels of SBT and of
CPZ
seemed to contribute to the high clinical efficacy. 8. Adverse reactions occurred in 2.8% (6/217) of the patients, and consisted primarily of rash and diarrhea. Laboratory abnormalities were observed in 8 patients during the study. These were elevations of S-GOT and S-GPT, and eosinophilia. 9. SBT/
CPZ
is a very useful drug in the treatment of lower respiratory tract infections as it has become available just in time when increase in resistant organisms to beta-lactams is notable.

Sulbactam/cefoperazone (SBT/
CPZ
) was used in pediatric patients with acute infections, and the following results were obtained. SBT/
CPZ
was administered to 18 pediatric patients with acute infections. Out of them, 14 patients, i.e., 3 with acute tonsillitis, 1 with acute laryngitis, 1 with acute bronchitis, 4 with acute pneumonia, 4 with bronchopneumonia, 1 with pyothorax, were adopted for the evaluation, and the other 4 were excluded because they were judged inadequate for clinical efficacy evaluation. The clinical efficacy of SBT/
CPZ
was assessed as excellent in 4, good in 9 and fair in 1. The effective rate was 92.9%. In 6 cases causative organisms were detected, i.e.,
Haemophilus
influenzae in 3, Klebsiella in 1 and Staphylococcus aureus in 2 cases. Eradication of these organisms was confirmed in all cases except for 1 patient with pyothorax caused by S. aureus. The doses used in 12 out of the evaluated 14 cases ranged from 58.4 to 80 mg/kg/day, 84.1 mg/kg/day was used in 1 case and 101.4 mg/kg/day was used in 1 case with pyothorax. Patients with severe infections were generally given large doses. The frequency of administration was 3 times per day except 1 case, and intravenous drip infusion was used in all cases. The duration of treatment was 2- less than 3 days for 7 cases, 3-5 days for 6 cases and 9 days for 1 case (pyothorax). No clinical side effects were observed in any case. In laboratory examinations, a slight elevation of GOT was observed in 1 case, but no abnormal findings in the other cases. From the above results, SBT/
CPZ
was considered to be a highly useful drug in the treatment of pediatric infections.

The efficacy and safety of sulbactam/cefoperazone (SBT/
CPZ
) were evaluated in 42 patients with respiratory tract infections, including pneumonia (29 patients) and lower respiratory tract infections (5 patients). Overall clinical efficacy rates (excellent + good) were 79% in pneumonia and 80% in respiratory tract infections in 34 patients evaluated for clinical efficacy. It was excellent that the clinical efficacy rate was 92% in mild and moderate pneumonia. Pathogens isolated from sputa were 31 strains, including 8 strains of Pseudomonas aeruginosa, 7 of Streptococcus pneumoniae, 3 of Staphylococcus aureus and 3 of
Haemophilus
influenzae. Since the isolates were eradicated in 18 strains, replaced in 3, unchanged in 2 and unknown in 8, the overall eradication rate was 91%. The eradication rates were 89% in beta-lactamase producing strains and 100% in beta-lactamase positive sputum, and excellent or good in 19 (83%) of 23 patients with beta-lactamase negative sputum. The eradication rate was 88% in 5 patients with beta-lactamase positive sputum. One patient experienced a moderate rash. Abnormal laboratory test values were observed in 10 patients (26.3%), but these abnormalities were mild and transient. These results suggested that SBT/
CPZ
was effective and safe for the treatment of respiratory tract infections caused by beta-lactamase producing as well as beta-lactamase non-producing bacteria.

A drug susceptibility test of the combination drug TAZ/PIPC, which consists of a newly developed beta-lactamase inhibitor, tazobactam (TAZ), and one of penicillin antibiotics, piperacillin (PIPC), with combination ratio of 1:4 in potency, was conducted with stock strains and clinical isolates. The clinical efficacy and safety of its injection was also evaluated in children with a variety of infectious diseases. The results were as follows: 1. In susceptibility test, 114 strains from 4 species of stock strains were treated with 8 drugs, that is, TAZ/PIPC, PIPC, penicillin G (PCG), ampicillin (ABPC), cefotiam (CTM), cefotaxime (CTX), ceftazidime (CAZ), and sulbactam/cefoperazone (SBT/
CPZ
). Of three clinically isolated species from patients, Staphylococcus aureus (S. aureus) was treated with TAZ/PIPC, PIPC, methicillin (DMPPC), CTM, CTX, and SBT/
CPZ
, and the others were treated with the same drugs except for DMPPC. The MICs were measured for these bacterial strains inoculated at the concentration of 10(6) CFU/ml. The MIC90 values of TAZ/PIPC against 45 strains of Streptococcus pyogenes (S. pyogenes), one of the stock cultures of Gram-positive cocci, were 0.05 microgram/ml and similar to those of PIPC, CTM, CAZ, and SBT/
CPZ
. The MICs of TAZ/PIPC for 28 strains of Streptococcus agalactiae (S. agalactiae) were 0.39 microgram/ml and similar to those of PIPC, CTM, CAZ, and SBT/
CPZ
. As for Gram-negative bacilli, the MIC90 of TAZ/PIPC against 10 strains of Bordetella pertussis (B. pertussis) were 0.10 microgram/ml and similar to those of PIPC. The MIC90 of TAZ/PIPC against 31 strains of
Haemophilus
influenzae (H. influenzae) were 0.05 microgram/ml and similar to those of PIPC, CTX, and SBT/
CPZ
. Regarding Gram-positive cocci isolated from patients received this combination drug, the MIC90 of TAZ/PIPC against 2 strains of S. aureus, a non beta-lactamase producing strain and a low-beta-lactamase producing strain, were 0.78 microgram/ml and 3.1 micrograms/ml, respectively; the former value was similar to those of PIPC, DMPPC, CTM, and CTX, and the latter was similar to those of PIPC, DMPPC, CTX, and SBT/
CPZ
. Of 4 strains of Streptococcus pneumoniae, 2 strains were inhibited at 0.05 microgram/ml, and the others at 1.56 micrograms/ml; both values were similar to those of PIPC, SBT/
CPZ
. As for Gram-negative bacilli, 6 of 7 strains of H. influenzae did not produce beta-lactamase and 1 strain was a high producer. The MICs of TAZ/PIPC against beta-lactamase nonproducing strains were < or = 0.025 microgram/ml in 5 strains and 0.39 microgram/ml in 1 strain, and the values were similar to those of PIPC and SBT/
CPZ
. While the MIC of TAZ/PIPC against the high beta-lactamase producing strain was 0.78 microgram/ml; similar to that of SBT/
CPZ
and smaller than that of PIPC. 2. The results of clinical effects on 7 diseases in 33 cases were as follows: TAZ/PIPC was clinically judged "excellent" in 17 (51.5%); good in 14 (42.4%); fair in 2 (6.1%). No case with no response was seen in this study, and the total efficacy rate of "excellent" and "good" was 93.9%. 3. Bacteriological effects were evaluated in 17 strains of 4 species, and all of them were eradicated. 4. Adverse reactions were judged in 35, which consisted of 33 in which the clinical effects were evaluated and 2 dropped from this study. Of these cases, diarrhea was observed in 4 (11.4%). 5. Laboratory tests revealed an increase in platelets in 1 of 32 cases (3.1%), and eosinophilia in 2 of 29 cases (6.9%). Biochemical profile showed an increase in GPT alone and abnormal increases in both GOT and GPT in 1 each out of 21 cases.

The antimicrobial activity of various antibiotics against clinical bacterial isolates recovered from patients with infectious diseases at the medical facilities in the Kanto region between March and September 2006 was evaluated. A total of 1030 clinical isolates were available for susceptibility tests: 420 aerobic Gram-positive organisms, 520 aerobic Gram-negative organisms, 30 anaerobic Gram-positive organisms and 60 anaerobic Gram-negative pathogens. Antimicrobial susceptibility data for Streptococcus pneumoniae and
Haemophilus
influenzae isolates from pediatric and adult patients were analyzed separately. Panipenem (PAPM), imipenem (IPM), meropenem (MEPM), biapenem (BIPM), doripenem (DRPM), cefozopran (CZOP), cefepime (CFPM), and sulbactam/cefoperazone (SBT/
CPZ
) were used as test antibiotics. PAPM, IPM and DRPM exhibited excellent in vitro antibacterial activities against methicillin-susceptible Staphylococcus, with all isolates exhibiting a MIC of < or =0.06 microg/mL. Against Streptococcus including penicillin-resistant S. pneumoniae, PAPM demonstrated the strongest antibacterial activity among the carbapenems with a MIC range of < or =0.06 to 0.12 microg/mL. Against Enterobacteriaceae, MEPM showed the strongest antibacterial activity, and PAPM had comparable activity to IPM. Against the extended-spectrum beta-lactamase producing Escherichia coli, Klebsiella species and Proteus species, the MICs for the cephems were high, however, those for the carbepenems were low. Against H. influenzae, PAPM had comparable activity to IPM. With respect to anaerobes, each of the carbapenems tested demonstrated almost the same strong antibacterial activity. In conclusion, 13 years has passed since PAPM was launched in 1993, PAPM still maintains potent antibacterial activity and is considered an effective antimicrobial agent for various types of infectious diseases.
