To 6 cases of children in 2 groups of 3 each, newly developed sulbactam/cefoperazone (SBT/CPZ) was given at 20 and 40 mg/kg by intravenous bolus injection, respectively, and the serum and urinary concentrations and recoveries of SBT and CPZ were determined. To 1 case of purulent meningitis, this drug was given at 40 mg/kg by intravenous bolus injection, and the cerebrospinal fluid and serum concentrations of SBT and CPZ were determined. Susceptibility tests to SBT/CPZ and CPZ of total 289 strains were conducted; Gram-positive cocci tested consisted of 26 S. aureus strains, 20 S. pyogenes strains and 21 S. pneumoniae strains, and Gram-negative bacilli consisted of 24 H. influenzae strains, 22 E. coli strains, 26 K. pneumoniae strains, 24 E. cloacae strains, 21 E. aerogenes strains, 19 Citrobacter sp. strains, 20 S. marcescens strains, 23 P. mirabilis strains, 23 indole-positive Proteus sp. strains and 20 P. aeruginosa strains. SBT/CPZ was given to total 43 cases at a mean daily dosage of 80.4 mg/kg, in 3 or 4 divided doses (6 cases in 3 and 37 cases in 4), 1 case receiving the drug by drip infusion over 30 minutes (in 3 divided doses) and all the other 42 cases by intravenous bolus injection, for 7 days on an average. They consisted of 2 cases of tonsillitis, 1 case of otitis media, 1 case of otitis media associated with mastoiditis, 30 cases of pneumonia, 1 case of suspected septicemia, 1 case of purulent meningitis, 5 cases of urinary tract infection, 1 case of purulent lymphadenitis and 1 case of submaxillaritis. And the clinical and bacteriological effects were evaluated. Also, side reactions and laboratory examinations for abnormal values due to administration of this drug were made on 47 cases including 4 drop-outs. The following results were obtained: After administration of this drug to 2 groups of 3 children each at 20 and 40 mg/kg by intravenous bolus injection, mean serum concentrations of both SBT and CPZ reached the peaks in 5 minutes; SBT levels were 60.9 and 124.7 micrograms/ml for the 2 groups and CPZ levels were 105.0 and 214.1 micrograms/ml, respectively. In either group, CPZ levels were 1.7 times as high as SBT levels, and there was observed a dose-response in both. In the 20 mg/kg group, mean half-lives of SBT and CPZ were 0.96 and 1.24 hours, respectively, and in the 40 mg/kg group, they were 1.01 and 1.32 hours, CPZ values tending to be longer.(ABSTRACT TRUNCATED AT 400 WORDS)

As a result of conducting experimental and clinical tests with the newly developed cephalosporin, cefoperazone (CPZ), the following conclusions were obtained: (1) When tested against 10 strains of Staphylococcus aureus and 16 strains of Staphylococcus epidermidis, the antibacterial activity of CPZ was found to be weaker than that of CEZ. Against 5 strains of A-beta-Streptococcus and 4 strains of Streptococcus pneumoniae, both CPZ and CEZ exhibited similar excellent antibacterial activity. CPZ was effective against 18 strains of Escherichia coli though its activity was influenced by the amount of inoculated bacteria present. Against 15 strains of Haemophilus influenzae and 10 strains of Haemophilus parahaemolyticus, CPZ was found to be more effective than CEZ though several high-resistant strains were noted. CPZ also showed more excellent antibacterial activity than CEZ against 4 strains of Haemophilus parainfluenzae, 5 strains of Klebsiella pneumoniae, 8 strains of Salmonella sp., 4 strains of Pseudomonas aeruginosa and 4 strains of Proteus sp. (2) The mean half-life in the blood following intravenous injections of 25 mg/kg and 10 mg/kg of CPZ to three children was 70 minutes. (3) One hour after intravenous injection of 25 mg/kg of CPZ to 3 cases of aseptic meningitis, drug concentration in the cerebrospinal fluid (CSF) was 1.20 mcg/ml, less than 0.39 mcg/ml and 1.55 mcg/ml. In one case, the CSF/serum ratio was 2.7%. (4) The average recovery rate in the urine of children who had received intravenous administrations of 25 mg/kg (3 children) and 10 mg/kg (1 child) was 17.8% between 0 and 6 hours. (5) Eighteen pediatric patients received CPZ in doses ranging from 48 to 170 mg/kg divided three-four times a day. They were RTI in 7, URI in 5, UTI in 5, SSSS in 1 and enteritis in 1 children. The clinical effectiveness of CPZ was judged to be remarkedly effective in 11 children, effective in 5 children and ineffective in 3 children, with an overall effective rate of 84.2%. One patient of tonsillitis combined sinusitis was considered 2 cases. The three cases in which the drug was found to e ineffective were 2 cases of pyothorax and 1 case of sinusitis. (6) Side effects were 1 case of eosinophilia, 2 cases of elevation of GOT and GPT, and 1 case of mild elevation of GOT. All were considered to be minor.

Ceftezole (CTZ) was administered to 20 patients with hematopoietic malignancy complicated with infections. These patients consisted of 7 cases of AML, 2 ALL, 2 AMMoL, 1 APL, 1 blast crisis of CML, 2 HD, and 5 NHL. In 13 cases, sites of infection were determined and causative organisms were identified. In other 7 cases, sites of infection or causative organisms were unknown. In the former 13 cases, pneumonia was demonstrated in 6 patients, tonsillitis in 4 patients, pyelonephritis in 2 patients and sepsis in 1 patient. Klebsiella was separated from 5 patients as the causative organisms, E. coli from 2 patients, E. coli and Pseudomonas aeruginosa from 1 patient, Pseudomonas cepacia from 1 patient, Streptococcus viridans from 2 patients, Proteus from 1 patient and Torulopsis from 1 patient. Gram-negative rods were separated from 10 of the 13 cases (77%) as the causative organisms. CTZ was administered intravenously in dose from 4 g to 16 g per day combined with other antibiotics (AMK, GM, DKB, TOB, SBPC, CBPC, LC, ST). The response rate in 12 cases of acute leukemia and in 7 cases of malignant lymphoma was 58% and 43%, respectively. Infections occurred in 4 patients with less than 100 neutrophil per mm3 did never favorably responded even with CTZ.

Fundamental and clinical studies were made on cefadroxil, a new oral cephalosporin, and the following results were obtained. (1) Antibacterial activity of the drug against S. aureus, S. epidermidis, E. coli, Klebsiella, Salmonella and P. mirabilis was almost equal to that of cephalexin. The MIC of indole positive Proteus. Enterobacter, Citrobacter, S. marcescens and P. aeruginosa to cefadroxil was higher than 100 microgram/ml in almost all strains. (2) Serum concentrations following an oral administration of 10.0 to 14.3 mg/kg of cefadroxil dry syrup was highest at 2 hours in 2 cases and 1 hour in 1 case, respectively, which were 13.4 to 17.1 microgram/ml, and 1.8 to 6.8 microgram/ml at 4 hours with an T 1/2 of 1.04 to 1.62 hours and apparently longer continuation of serum concentration than that of cephalexin. Urinary recovery rate was 75-96% up to 6 hours. (3) Fourteen patients, i.e., 6 with tonsillitis and 8 with urinary tract infection, were treated with a daily oral dose of 30-50 mg/kg divided in 4 doses except 1 case divided in 3 doses. The overall efficacy rate was 100%, i.e., excellent in 13, good in 1 and no failure. Causative organisms disappeared in all cases. (4) Adverse reactions, such as diarrhea and skin rash, were not noted at all and 1 case presented a mild elevation of GOT and GPT. (5) Taste and flavor of the drug was well palatable to children. (6) Based on the above results, it is concluded cefadroxil dry syrup is a new potent cephalosporin for oral use in the treatment of acute bacterial infection in children. Daily dose of 40 mg/kg in 3-4 divided doses appeared to be appropriate.

Loracarbef is an orally administered member of a new synthetic class of beta-lactam antibiotics, the carbacephems, which is characterised by enhanced chemical stability. At low concentrations (< 2 mg/L) in vitro, it inhibits Streptococcus pneumoniae, S. pyogenes, beta-haemolytic streptococci groups B, C and G. Proteus mirabilis and Moraxella catarrhalis, including beta-lactamase-producing strains. At therapeutic plasma concentrations it is also active in vitro against most strains of Staphylococcus aureus, S. saprophyticus, Escherichia coli and beta-lactamase-positive and -negative strains of Haemophilus influenzae. Like other beta-lactams, loracarbef is inactive against methicillin-resistant strains of S. aureus. When administered at dosages of 200 to 400 mg twice daily, the clinical and bacteriological efficacy of loracarbef is comparable with that of amoxicillin and amoxicillin/clavulanic acid in patients with upper or lower respiratory tract infections, and comparable with that of cefaclor in treating infections of the lower respiratory tract, skin and skin structures and urinary tract. Loracarbef and phenoxymethylpenicillin (penicillin V) were equally effective in treating streptococcal pharyngitis and tonsillitis. Loracarbef is generally well tolerated by all age groups and causes less diarrhoea than amoxicillin/clavulanic acid. It is administered twice daily. It offers a suitable alternative to other orally administered antibiotics for the treatment of mild to moderate infections caused by susceptible organisms.

Two Saudi girls aged 8 years and 5 years were seen over a period of 6 years and 5 years. Their clinical presentations consisted of recurrent bilateral otitis media, repeated episodes of tonsillitis and chest infection. Cultures from the ears grew on numerous occasions Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeroginosa, Proteus species and Providencia species. The 8-year-old had a serum IgE level of 1431 iu/L, with normal levels of other immunoglobulin classes. The 5-year-old had an immunoglobulin E value of 1119 iu/L with normal values of other immunoglobulin classes. Both were human immuno-deficiency virus negative and no other causes for elevated immunoglobulin E were found. The mothers of both cases had elevated immunoglobulin E levels of 1216 iu/L and 1992 iu/L. Both fathers had normal IgE levels. A 13-year-old sibling of case one had a grossly elevated immunoglobulin E level of 2259 iu/L. She had diffuse lamellar icthyosis and recurrent episodes of chest infection and conjunctivitis. There was a good clinical response of patient one to monthly intravenous human immunoglobulin.

Cefuroxime is the first commercially-available second-generation cephalosporine to be widely used in therapy; it is a semi-synthetic cephalosporin obtained from the 7-cephalosporanic acid nucleus of cephalosporin C. Cefuroxime axetil is the acetoxyethyl ester of cefuroxime. The majority of micro-organisms associated with respiratory infections are highly sensitive to cefuroxime. These include Haemophilus influenzae, Streptococcus pneumoniae, Streptococcus pyogenes and the other streptococci (excluding group D streptococci), and Moraxella catarrhalis. Bacteria sensitive to cefuroxime include the enterobacteria (Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Salmonella and Shigella and Straphylococcus aureus (methicillin-sensitive strains). The pharmacokinetic studies show that the maximum plasma concentration of cefuroxime after oral administration of 250 mg and 500 mg of cefuroxime axetil after a meal are respectively 4.6 and 7.9 mg/l. The absolute bioavailability of tablets is 68% (extremes 63-73%) after oral administration of 500 mg cefuroxime axetil. The protein binding is 33+/-5.7%. Tissue diffusion was studied in the interstitial fluid, the bronchial mucosa, the tonsils, and the bronchial secretions. Cefuroxime axetil is available as capsule-shaped tablets containing 125, 250 or 500 mg. An oral suspension dosage form for paediatric purposes is also available as granules in multidose bottles and sachets. Constitution gives a suspension containing 125 mg or 250 mg cefuroxime (as cefuroxime axetil). Cefuroxime axetil is indicated for the treatment of infections caused by susceptible bacteria. Indications include: lower respiratory tract infections (e.g., acute and chronic bronchitis and pneumonia); upper respiratory tract infections (e.g., ear, nose and throat infections such as otitis media, sinusitis tonsillitis and pharyngitis); genito-urinary tract infections (e.g., pyelonephritis, cystitis and urethritis, gonorrhoea, acute uncomplicated gonococcal urethritis and cervicitis); and skin and soft tissue infections (e.g., furunculosis, pyoderma and impetigo). For most infections, a dose of 250 mg twice daily is appropriate. In some urinary tract infections, 125 mg twice daily has been shown to be effective. If pneumonia is suspected or in more severe lower respiratory tract infection, doses of 500 mg bd should be used. Uncomplicated gonorrhoea has been shown to respond to a single 1-g dose of cefuroxime axetil. Adverse reactions to cefuroxime have generally been mild and transient in nature (gastrointestinal disturbances, including diarrhoea, nausea and vomiting).
