Twenty-five infants and children with acute osteomyelitis (n = 7), suppurative arthritis (n = 11), or both (n = 7) were treated with imipenem and cilastatin sodium. Patients ranged in age from 5 months to 11.3 years. Needle aspiration of infected sites was performed in all patients, and 11 (44%) required further surgical drainage. Imipenem and cilastatin sodium in a dosage of 100 mg/kg/d was used for children 3 years of age or younger, while older ones received 60 mg/kg/d intravenously, divided in four equal doses. Bacterial pathogens were identified in 15 patients (60%): Staphylococcus aureus in five, Haemophilus influenzae b in four, Pseudomonas aeruginosa in two, Streptococcus pneumoniae in one, group A Streptococcus in one, Kingella kingae in one, and Citrobacter amalonaticus in one. All isolates were susceptible to imipenem in vitro. Imipenem and cilastatin therapy was continued for a median of six days followed by treatment with appropriate orally administered antibiotics. Median peak serum bactericidal titers after imipenem and cilastatin infusions were 1:512 for S aureus, 1:32 for H influenzae b, 1:512 for streptococci, and 1:16 for gram-negative rods. All but one patient with P aeruginosa osteomyelitis responded favorably to imipenem and cilastatin. The median duration until resolution of symptoms was six days. Imipenem and cilastatin infusions were well tolerated, and side effects included maculopapular rash in one patient, watery diarrhea in one, and mild transient elevation of alanine aminotransferase levels in three. Because of imipenem and cilastatin's unusually broad spectrum of activity and its relative safety, this drug combination can be used for the initial, empiric therapy of acute bone and joint infections in pediatric patients.

Twenty-one patients with serious gram-negative infections were treated with aztreonam. Twenty of these were clinical and microbiologic cures; there was one clinical improvement with microbiologic persistence. No bacteria became resistant. Cure rates were: bone and joint (11 of 11); skin and soft tissue (six of six); pneumonia (two of two); perinephric abscess (one of one); and intra-abdominal abscess (zero of one). The bacteria responsible for these infections included Pseudomonas aeruginosa (12), Serratia marcescens (two), Enterobacter gergoviae (three), Enterobacter aerogenes (two), Escherichia coli (one), Citrobacter diversus (one), and Hemophilus influenzae (one). Aztreonam was well tolerated. Significant serum glutamic-oxaloacetic transaminase/serum glutamic-pyruvic transaminase elevations developed in three patients, but none was symptomatic and all resolved after therapy was stopped. Two patients in whom a rash developed were receiving other antibiotics (vancomycin and metronidazole), making the cause of the rash unclear. Diarrhea developed in a single patient with Pseudomonas osteomyelitis, who also was receiving cefazolin for Staphylococcus aureus superinfection of his decubitus ulcer. Aztreonam was highly effective against gram-negative bacilli, including P. aeruginosa. The only clear-cut side effect was an asymptomatic rise in serum glutamic-oxaloacetic transaminase/serum glutamic-pyruvic transaminase levels in three patients.

Timentin is an exciting new antibiotic agent that is a combination of ticarcillin and clavulanic acid. Forty-seven patients with osteomyelitis received 3.1 g of Timentin intravenously every six hours. The mean duration of therapy was 32 days. The diagnosis was made by bone biopsy; bone biopsy was repeated at the completion of therapy. The bacterial etiology was predominately gram-positive organisms. Of the organisms isolated, Staphylococcus aureus was the most common isolate and represented 39 percent of the total isolates. Streptococcus species were isolated in 13 percent, Group D Enterococcus in 15 percent, Pseudomonas aeruginosa in 10 percent; 23 percent of the isolates were other gram-negative organisms. All but one organism were initially sensitive to Timentin. Three resistant organisms were isolated during therapy. Twenty-seven patients were classified as having a cure, based on no growth on repeat bone biopsy cultures and clinical signs of bone healing. Twenty-two patients returned for follow-up (one to nine months after therapy) and had no evidence of infection; however, because of the short follow-up period, these patients were classified as showing improvement. Six patients had adverse reactions to Timentin: two had mild allergic phenomena and two had prolonged bleeding times. In all four, therapy was discontinued. Two patients had a transient, mild elevation in the level of serum glutamic-pyruvic transaminase (less than twice normal levels). This new agent looks exciting for therapy of both gram-positive and gram-negative bacterial osteomyelitis.

Aztreonam (AZT), a new synthetic monocyclic beta-lactam antibiotic, which is resistant to beta-lactamase and has a strong and specific activity against aerobic Gram-negative bacteria including Pseudomonas aeruginosa. The patients of 13 cases with localized peritonitis due to acute appendicitis, 3 cases with panperitonitis (1 case with perforative appendicitis, 1 with acute cholecystitis and 1 with pancreatic necrosis) and 4 cases with skin and soft tissue infection (anal fistula and abdominal abscess etc.) were treated by AZT. AZT was administered in a dose of 1 g twice a day by intravenous drip infusion using 100 ml-volume bottle preparation with saline for 4 to 10 days. Clinical efficacy was rated excellent in 2 cases, good in 16 cases, fair in 1 case and poor in 1 case (efficacy rate 90.0%). Adverse effects were small skin rash in 1 case, and increased GOT and GPT in 1 case. No adverse effect was recognized in other cases. Therefore, AZT appears to be very useful drug when used for chemotherapy of infectious diseases in surgery.

A daily dose of 2 or 4 grams of sulbactam/cefoperazone (SBT/CPZ) by drip infusion was given to 12 patients with gynecological infections and the results were as follows. The clinical effect was judged excellent in 2 cases, good in 9 cases, and poor in 1 case and the effectiveness rate was 91.7%. Except for Streptococcus faecalis, the bacteriological effect was sufficient. A good effect was also seen in Pseudomonas cepacia organism resistant to other cephem antibiotics. Diarrhea was observed in 1 patient, and increases in GOT and GPT, possibly attributable to concomitantly used anticancer agents, were detected in another patient. In conclusion, SBT/CPZ with a 91.7% efficacy rate was useful in infections caused by beta-lactamas producing organisms and, thus, a useful agent for gnecological infections. (author's modified)

From the laboratory and clinical studies on ceftizoxime (CZX), the following results were obtained 1) CZX was compared with cefazolin (CEZ) for in vitro activity against 6 standard strains and clinically isolated strains of Staphylococcus aureus (19 strains), Staphylococcus epidermidis (14), Proteus sp. (17), Escherichia coli (3), Klebsiella sp. (3) and Pseudomonas aeruginosa (13). While somewhat less active against Gram-positive cocci than CEZ, CZX was far more active than CEZ against Gram-negative bacilli. 2) The time course of mean serum CZX levels in 2 patients given a single intravenous dose of 10 mg/kg was as follows: 24.9 microgram/ml at 15 minutes, 18.5 microgram/ml at 30 minutes, 13.2 microgram/ml at 1 hour, 6.4 microgram/ml at 2 hours and 2.7 microgram/ml at 4 hours. The mean serum half life was 1.36 hours. The mean tonsil concentrations of CZX 30 minutes after a single intravenous dose of 0.5 g and 1.0 g were 5.9 microgram/g and 9.6 microgram/g. respectively, with the ratio to the serum concentration of 0.33 and 0.32. 3) CZX was given to 28 patients with ear, nose, and throat infections, and overall rate of effectiveness was 92.3%. No clinical side effects were observed. Changes in laboratory test findings included slightly elevated GOT and/or GPT in 3 cases.

Fundamental and clinical studies of ceftizoxime, a new cephalosporin antibiotic, in children led to the following results. 1. Ceftizoxime compared favorably with cefazolin (CEZ) and cefmetazole (CMZ) for in vitro activity against clinically isolated strains of Staphylococcus aureus (31 strains), Escherichia coli (29), Klebsiella pneumoniae (30) and Pseudomonas aeruginosa (16). While somewhat less active against S. aureus than CEZ and CMZ, ceftizoxime was far more active than these 2 cephalosporin antibiotics against the test strains of E. coli and K. pneumoniae, which included strains resistant to the 2 drugs. Ceftizoxime was not particularly active against Ps. aeruginosa, but this seeming disadvantage was offset by the absolute ineffectiveness of the 2 reference drugs on this obstinate organism. 2. The time course of mean serum ceftizoxime levels in 3 pediatric patients of 5--10 years old given a single intravenous dose of 20 mg/kg was as follows: 45.4 micrograms/ml at 15 minutes, 40.4 micrograms/ml at 30 minutes, 22.1 micrograms/ml at 1 hour, 10.4 micrograms/ml at 2 hours, 2.9 micrograms/ml at 4 hours and 0.9 microgram/ml at 6 hours. The mean serum half life was 1.12 hours. The mean urinary levels of ceftizoxime at serial 2-hour collection intervals were as follows: 2,477 micrograms/ml for 1--2 hours, 1,235 micrograms/ml for 2--4 hours and 462 micrograms/ml for 4--6 hours. The mean urinary recovery up to 6 hours was 61.0%. 3. The clinical response of 28 children with infection to ceftizoxime treatment was 'excellent' in 22 children, 'good' in 4, and 'poor' in 2. These children comprised 11 with acute pneumonia, 3 with acute bronchitis, 4 with acute pyelonephritis, 2 each with acute purulent arthritis and acute enterocolitis, and 1 each with acute purulent tonsillitis, acute purulent lymphadenitis, furunculosis, subcutaneous abscess, subdural abscess and sepsis. The overall rate of effectiveness was 92.9%. Successfully eradicated strains in the bacteriological sense consisted of 4 strains each of H. influenzae and E. coli, 1 strain each of P. morganii, S. pneumoniae and S. pyogenes, 1 of the 2 strains of S. enteritidis, and 1 of the 3 strains of S. aureus. The overall rate of bacteriological effectiveness was 81.3%. No clinical side effects were observed. Changes in laboratory test findings included slightly and transiently elevated GOT and GPT in 1 child and GOT alone in another child.

Mice, injected with either live cells of Pseudomonas aeruginosa, or its slime glycolipoprotein (GLP), developed similar lethal syndromes. Within 14 h, biochemical changes in the sera, such as increased urea, aspartate aminotransferase, alanine aminotransferase, and creatinine, as well as decreased glucose, albumin, total protein, uric acid, and alkaline phosphatase, indicated liver and renal dysfunction. These marked alterations were in contrast with the minimal histopathological changes that occurred in these organs. Either live cell or GLP challenge also induced haemolysis in vivo. Immunization with GLP protected mice against most biochemical changes when challenged with live cells but did not protect GLP-challenged mice against the biochemical alterations assayed in the sera.

A total of 466 patients were treated with cefoperazone. The drug was usually administered by drip infusion of 2 to 4 gm/day. Therapy was described as markedly effective and moderately effective in 64 of 77 patients (83.1%) treated for urinary tract infections; 253 of 316 patients (80.1%) treated for respiratory infections; 37 of 48 patients (77.1%) treated for liver biliary duct infections; ten of 16 patients (62.5%) treated for septicemia; and seven of nine patients (77.8%) being treated for other infections. Overall, cefoperazone was effective 79.6% of all patients treated. With respect to bacteriological activity, the overall eradication rate for gram-negative organisms (including Pseudomonas aeruginosa, Klebsiella sp, Escherichia coli, Haemophilus influenzae, Enterobacter sp, and Proteus sp) was 81% (182/225) and for gram-positive (Staphyloccocus aureus, Streptococcus pneumoniae and Streptococcus faecalis) 90% (36/40). Of 205 patients who failed to respond to previous antibiotic therapy, 67.8% were treated effectively with cefoperazone. Side effects, such as skin eruption, pyrexia and diarrhea, occurred in only 4.8% of patients treated, while laboratory abnormalities, such as elevated glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, alkaline phosphatase, and eosinophil values, occurred in only 6.4% of the treated patients. None of these abnormal values were of clinical significance.

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.
