30 patients with recurrent tonsillitis were treated with amoxycillin/clavulanic acid (500 mg/125 mg) t.i.d. for 10 days. The most often isolated potential aerobic pathogenic bacteria were Staphylococcus aureus, Streptococcus milleri and Haemophilus parainfluenzae. Group A streptococci were isolated from 7 patients. Anaerobic cocci and Bacteroides species were the dominating anaerobic bacteria isolated from the tonsils. Tonsillar cultures were taken before antibiotic treatment started, on days 11-12, day 30, and day 90. Beta-lactamase producing aerobic and anaerobic bacteria were present in 13 patients prior to treatment, on days 11-12 in 18 patients, on day 30 in 15 patients, and on day 90 in 13 patients. Group A streptococci were eradicated in 6/7 patients. In the aerobic tonsillar microflora, the numbers of viridans streptococci decreased during treatment but were normalized after 30 days. Only minor changes in the numbers of other aerobic microorganisms occurred during the investigation. The effect on the anaerobic microflora was minor and no new colonizing microorganisms were isolated during or after antibiotic treatment. All patients except one were cured on days 11-12. Five patients had another episode of tonsillitis during the observation period of 3 months. The antibiotic treatment was well tolerated in most patients and mild adverse events such as nausea, vomiting and diarrhoea were observed in 3 patients.

A total of 33 patients with bacterial meningitis were treated with single daily doses of ceftriaxone (CTR 100 mg/kg/day i.v.) for a median duration of 13 days. Pathogens isolated by culture and/or determined by latex agglutination were 15 Haemophilus influenzae b, 7 Neisseria meningitidis, 2 Streptococcus pneumoniae, 1 group B streptococcus, 2 Streptococcus viridans and 2 Staphylococcus epidermidis. In 4 cases a diagnosis of purulent meningitis could only be made by means of the inflammatory liquor parameters. All cerebrospinal fluid (CSF) drug levels even at the end of the dosing interval were at least 10-fold higher than the MICs of the respective bacterial isolates. The average penetration of CTR into the CSF was 6.6%. Within 12-46 h after the first dose, control spinal taps were performed. Cultures were sterile in all cases. Side effects encountered were diarrhea, exanthema, neutropenia and transient elevation of glutamic oxaloacetic transaminase, but none caused a change of therapy. One patient developed a biliary concrement. No patient died; 5 patients had prolonged fever (greater than 5 days), and 2 were left with persistent hearing deficiencies. CTR can be recommended as a safe and effective antibiotic agent for once daily treatment of bacterial meningitis in children.

Cefuroxime axetil, a new beta-lactamase-stable cephalosporin, was compared with cefaclor for the treatment of acute bacterial maxillary sinusitis in 106 adult patients. Direct sinus aspirations for quantitative bacterial culture were done for all patients before treatment; aspiration was repeated for most patients after treatment. Pretreatment sinus aspirates were positive for 63 of 134 sampled sinuses. Of specimens yielding at least 10(4) CFU/mL, Haemophilus influenzae (38%) and Streptococcus pneumoniae (37%) were the most common pathogens. Ten (42%) of 24 strains of H influenzae, 2 (40%) of 5 Haemophilus parainfluenzae, and all 3 isolates (60%) of Branhamella catarrhalis produced beta-lactamase. Cefuroxime axetil, 250 mg twice a day, was compared with cefaclor, 500 mg three times a day. Among culture-positive sinuses, bacteriologic cure was achieved in 36 (95%) of 38 sinuses and 15 (71%) of 21 sinuses treated with cefuroxime axetil and cefaclor, respectively. The overall frequencies of adverse events were similar between drugs, although cefuroxime axetil was associated with more frequent diarrhea. Cefuroxime axetil was an effective therapy for the treatment of acute bacterial maxillary sinusitis in adults.

Cefpodoxime proxetil (CPDX-PR, CS-807) dry syrup was administered orally to 31 patients with various infections at daily dose levels between 5.4 and 10.9 mg/kg divided into three doses. 1. The subjects were 3 patients with urinary tract infections, 25 with tonsillitis and 1 patient each with bronchitis, pneumonia, and cervical lymphadenitis. Clinical effects were excellent in 16 cases, good in 14, and fair in 1 (tonsillitis), with an overall efficacy rate of 96.8%. 2. Organisms suspected as pathogens were 32 strains (6 strains of Staphylococcus aureus, 2 of Streptococcus pyogenes, 1 of Enterococcus faecalis, 15 of Haemophilus influenzae, 5 of Haemophilus parainfluenzae and 3 of Escherichia coli). Bacteriologically, eradication of pathogens were observed in 30 strains, decrease in one (H. parainfluenzae), and no change in another (E. faecalis), thus the eradication rate was 93.8%. 3. Side effect was observed in 1 case (slight eruption) but it was possible continue the treatment. Abnormal laboratory test values were observed in 1 case of a slight prolongation of prothrombin time and eosinophilia, but they were not serious. Diarrhea was not observed in any patients. 4. All the medication was done on schedule. No refusal of the drug occurred due to its taste or odor.

In a multicentre study, 220 consecutive cases of bacterial meningitis in children older than 3 months were randomised to treatment with chloramphenicol, ampicillin (initially with chloramphenicol), cefotaxime, or ceftriaxone. The drugs were given in four equal daily doses for 7 days, except ceftriaxone which was given only once daily. 200 cases could be assessed; the causative organisms were Haemophilus influenzae type b (Hib) in 146; meningococci (Mnc) in 32; pneumococci (Pnc) in 13; and other or unknown in 9. In patients with Hib meningitis, sterilisation of the cerebrospinal fluid occurred most rapidly with ceftriaxone. Otherwise, in terms of overall clinical recovery, normalisation of laboratory indices, clinically significant adverse reactions, toxic effects, sequelae, and mortality rate, the treatment groups were very similar. However, there were 4 bacteriological failures, all in the chloramphenicol group. Also, the treatment was extended or changed in more cases in the chloramphenicol group than in the other groups. Chloramphenicol was thus inferior to the other three antimicrobials. Ampicillin is a good and cheap alternative, but there are difficulties with resistance. Easy administration tempts the use of ceftriaxone rather than cefotaxime but it causes diarrhoea. A 7-day course of ampicillin, cefotaxime, or ceftriaxone is sufficient in Hib, Mnc, or Pnc meningitis.

Seventy-one adult patients with 72 infections were treated, by random selection, with intravenous/oral ciprofloxacin or intravenously administered ceftazidime. Twenty-seven additional patients with 29 infections who were not appropriate for random assignment were treated in an open study with intravenously administered ciprofloxacin only; the latter infections were generally more serious or were caused by ceftazidime-resistant organisms. The most common doses were ciprofloxacin, 200 mg intravenously and 500 mg orally every 12 hours and ceftazidime, 1 to 2 g intravenously every eight to 12 hours. Forty-seven ciprofloxacin-treated infections and 31 ceftazidime-treated infections were evaluable for determination of efficacy. Infections included lower respiratory tract (21 infections), urinary (37 infections), skin/soft tissue (14 infections), bacteremia/endocarditis (four infections), colitis (one infection), and mastoiditis (one infection). Median minimal inhibitory concentrations of ciprofloxacin and ceftazidime were, respectively: for Enterobacteriaceae, Haemophilus influenzae, and Branhamella catarrhalis, no more than 0.06 and no more than 0.25 micrograms/ml; for Pseudomonas aeruginosa, 0.25 and 4 micrograms/ml; for Enterococcus faecalis, 1 and more than 32 micrograms/ml; and for Staphylococcus aureus, 0.25 and 8 micrograms/ml. Ciprofloxacin, 200 mg intravenously, yielded mean serum concentrations 0.5 and eight hours post-intravenous infusion of 2.3 and 0.7 micrograms/ml, respectively. Satisfactory clinical responses were achieved in 17 (81 percent) of 21 patients with intravenous/oral ciprofloxacin, 22 (71 percent) of 31 patients with ceftazidime, and 20 (77 percent) of 26 patients with intravenous ciprofloxacin. The most common treatment failures occurred in complicated skin/soft-tissue infections treated with intravenous/oral ciprofloxacin, complicated urinary tract infections treated with ceftazidime, and necrotizing P. aeruginosa pneumonia treated with intravenous ciprofloxacin; the pneumonia patients all had respiratory failure and had been previously unresponsive to treatment with other appropriate drugs. Serious adverse reactions were observed in three patients, seizures with intravenous ciprofloxacin in two patients, and Clostridium difficile diarrhea with ceftazidime in one patient. We conclude that sequential intravenous/oral ciprofloxacin and ceftazidime were comparable in efficacy and safety; the ability to change from intravenous to oral therapy is a major convenience. Intravenous ciprofloxacin was useful for more serious infections, often caused by ceftazidime-resistant organisms.

We have treated 42 episodes of pediatric infections with sulbactam/ampicillin since 1987. Included were 9 cellulitis, 9 urinary tract infections, 5 cervical lymphadenitis, 4 meningitis, 2 thoracic empyema, 2 osteomyelitis, 2 sepsis, 1 furuncle, 1 perianal abscess, 1 dental abscess, 1 peritonsillitis, 1 salmonellosis, 1 shigellosis, 1 peritonitis, 1 suppurative thyroiditis, 1 infective endocarditis. Responsible pathogens were Escherichia coli in 8, Staphylococcus aureus in 6, Hemophilus influenzae in 2, Streptococcus pneumoniae in 3, Streptococcus viridans in 2, Staphylococcus epidermidis in 1, Bacteroides fragilis in 1, Salmonella D1 in 1, Shigella sonnei in 1, Klebsiella pneumoniae in 1, Enterobacter agglomerans in 1, Acinetobacter calcoaceticus in 1, Enterobacter cloacae in 1, group A beta-hemolytic streptococcus in 1, and polymicrobial infection in 4 cases. Thirty-nine out of 41 (95%) clinically evaluable patients cured and all (34/34) bacteriologically evaluable patients eradicated their pathogens after treatment with sulbactam/ampicillin. Side reactions were seen in five patients; one maculopapular skin rash, one hemolytic anemia, two diarrhea, and one liver function impairment plus leukopenia. All these reactions were transient and did not require interruption of therapy. These results indicate that sulbactam/ampicillin is safe and effective in the treatment of common pediatric infections beyond the neonatal period.

Sultamicillin at an adult dose of 375-750 mg twice daily or a pediatric dose of 50 mg/kg/d provides effective outpatient/office therapy for community-acquired infections of the upper and lower respiratory tract, urinary tract, and skin/soft tissue structures. Given the incidence of Haemophilus influenzae and Branhamella catarrhalis in otitis media and the frequent occurrence of beta-lactamase-producing strains, it is particularly appropriate for the therapy of otitis media in infants and children. The increasing prevalence of beta-lactamase-producing pathogens in these infections, coupled with the fact that diagnostic bacteriology is often not available or practical in office practice, suggests that the broad use of sultamicillin might be desirable. Several factors support such usage: 1) the superiority of sultamicillin compared with the ampicillin commercial dosage form as a delivery system for ampicillin; 2) the possible occurrence at the infection site of beta-lactamase-producing organisms, not themselves pathogens, which nevertheless impair the activity of the beta-lactam antibiotic against sensitive pathogens; 3) the complementary binding of penicillin-binding proteins by ampicillin and sulbactam in ampicillin-sensitive organisms; 4) the lack of resistance development following repeated exposure of strains sensitive to sulbactam/ampicillin suggested by in vitro studies; and 5) the inability of sulbactam to induce beta-lactamase production. In addition to broad use in community-acquired infections, oral therapy with sultamicillin should also provide convenient outpatient follow-up for initial parenteral sulbactam/ampicillin therapy. Extensive testing of various laboratory parameters has revealed no evidence of systemic toxicity with sultamicillin. The only significant side effect of sultamicillin is diarrhea/loose stools, which, although a frequent complaint in some studies, is of mild to moderate severity and results in a low discontinuation rate.

The efficacy of cefonicid and of ceftriaxone, administered once daily for the treatment of lower respiratory tract bacterial infections (pneumonia or bronchitis), was evaluated and compared in 118 patients with chronic lung disease. The patients were randomly assigned to receive 1 gm of either drug, intravenously or intramuscularly, daily for three to 11 days (mean, seven days). Pathogenic bacteria were isolated from sputum in 59% of patients; Haemophilus influenzae and Streptococcus pneumoniae predominated. Clinical cure or improvement was noted in 95% and 93% of patients treated with cefonicid and ceftriaxone, respectively, and bacteriologic cure or improvement in 69% and 81% (the differences were not significant). Side effects were infrequent and similar in the two treatment groups, except that diarrhea was more common in the ceftriaxone group (11%, versus 4.4% in the cefonicid group). It is concluded that patients with chronic lung disease who experience acute exacerbations associated with infection caused by H influenzae or S pneumoniae, or other susceptible organisms, can be effectively treated with once-daily administration of either cefonicid or ceftriaxone.
