Four hundred ninety-nine nosocomial infections (with 657 isolates) in 288 Surgical Service patients were monitored from February 1986 to June 1987 (17 months) to determine the influence that pathogen or site of infection had on the length of hospital stay. Patients with upper respiratory and skin infections were more likely to have significantly longer length of stay than those with infections in other sites. Infections with Haemophilus influenzae and Pseudomonas aeruginosa were more likely to yield longer culture to discharge periods than other organisms in certain settings. Extended lengths of stay were common in patients with nosocomial infections.

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.

One hundred and eighty-seven children with identified bacterial meningitis were treated with intravenous cefotaxime: 15 patients were neonates, 79 infants, and 93 were aged from 1 to 14 years. Causative organisms were: Neisseria meningitidis in 80 cases, Streptococcus pneumoniae in 41, Haemophilus influenzae in 40, enteric gram-negative bacilli in 20 and Staphylococcus spp. in six. Enteric gram-negative bacilli included: Salmonella spp. in 14 cases, Klebsiella pneumoniae in two, and Escherichia coli, Enterobacter sakazakii and Acinobacter calcoaceticus in one each; in one case the organism was not specified. Daily dose of cefotaxime was 150 to 300 mg/kg. Concomitant treatment with an aminoglycoside was used in seven cases. One hundred and seventy-two patients (92.0%) were cured. Fever persisted for a mean of five days and meningeal signs for a mean of four days. Fifteen (8.0%) patients died: most [13] of them were admitted in coma, and two in shock. Death occurred in the first 48 h in ten cases. Sterilization of CSF was achieved in the first 72 h of treatment in 155 (90.1%) of the cured patients. Cefotaxime was well tolerated. CSF penetration of cefotaxime was evaluated in seven patients: concentrations ranged from 0.499 mg/l to 2.829 mg/l. Based on this clinical study, cefotaxime is an effective and safe drug for the treatment of childhood bacterial meningitis.

Sixteen hospitalized patients, aged between 10 and 76 years (mean: 34.3 years), with bacterial meningitis were treated i.v. with cefoperazone at daily doses of 4.5 g to 9 g. In two cases ampicillin was given in combination with cefoperazone during the last four days and the first five days of treatment, respectively. The following organisms were isolated: Neisseria meningitidis (n = 9), Haemophilus influenzae (n = 3), Escherichia coli (n = 2), Streptococcus pneumoniae (n = 2). Fourteen patients completely recovered from infection and the pathogens were eradicated; the treatment failed in only two patients and both were cured with alternative treatment. Furthermore, in 11 patients cefoperazone serum and CSF levels were determined four times during the first week of treatment (1st, 3rd, 5th and 7th days). No important side effects were recorded.

The in vitro activity of lomefloxacin, a new difluorinated quinolone, was compared to that of ciprofloxacin, ofloxacin, norfloxacin and other relevant antibacterial agents. Lomefloxacin and norfloxacin shared similar activity, whereas ofloxacin and in particular ciprofloxacin showed superior activity. Most gram-negative aerobes were susceptible to all four quinolones, 90% of isolates were inhibited by 1 mg/l. The gram-positive organisms were generally less susceptible, although 90% of Staphylococcus aureus isolates were inhibited by 0.5 mg/l of ciprofloxacin and ofloxacin; values for lomefloxacin and norfloxacin were 1 mg/l and 2 mg/l, respectively; susceptibility was not affected by methicillin resistance. Neisseria gonorrhoeae and Haemophilus influenzae were highly susceptible to the quinolones, especially ciprofloxacin. Penicillin/ampicillin-resistant isolates remained susceptible to the quinolones.

Clinical, microbiological and pharmacokinetic results are presented from studies in 186 patients treated with the new quinolone antimicrobial agents enoxacin, pefloxacin, ciprofloxacin or ofloxacin. Almost all had been admitted to hospital for acute purulent exacerbations of chronic bronchitis, associated mainly with Haemophilus influenzae, Streptococcus pneumoniae, Branhamella catarrhalis or Pseudomonas aeruginosa. The H. influenzae and B. catarrhalis strains were generally very sensitive to the quinolones and sputum concentrations of 1.3 to 4.5 mg/l exceeded the MICs (geometric mean values 0.07 to 0.44 mg/l) by a factor of more than 10. In contrast, P. aeruginosa was slightly less sensitive (geometric mean MICs 0.4 to 4.4 mg/l) and S. pneumoniae much less so (with geometric mean MICs between 0.84 and 6.7 mg/l) and a number of treatment failures were noted with these organisms. Various unwanted drug effects (mostly upper gastro-intestinal) were seen, particularly with enoxacin. The best clinical results were observed with ofloxacin, even with once daily dosage, but the results with the other quinolones could only be described as moderate.

Chronic bronchitis is responsible for 20,000 deaths per annum in France, i.e. 5 per cent of the overall mortality rate. Infection of the bronchi and lung tissue is a frequent cause of death in these patients. Acute on chronic bronchitis ranks fifth among the causes of disablement and admission to hospital. Pneumococci and Haemophilus influenza are the organisms most frequently isolated. the incidence and potential severity of acute episodes of infection account for the repeated use of antibiotics which carries a risk of promotion bacterial resistance. RU 41740 is a non-specific immunomodulator agent which reinforces the non-specific means of the respiratory tract against infections. Three double-blind, drug versus placebo and therefore reliable therapeutic trials have shown that the drug is effective in preventing airway infection. In patients with moderately advanced chronic bronchitis, RU 41740 reduces the number and duration of acute infectious episodes as well as antibiotic consumption. This positive effect persists in patients with chronic respiratory failure, including those who present with extensive bronchial dystrophy. RU 41740 is particularly effective in patients with numerous previous episodes of infection, but it also acts at all stages of chronic bronchitis.

The microorganisms that regularly infect patients with the acquired immunodeficiency syndrome (AIDS) have become well recognized. Most take advantage of defects in T-lymphocyte function, but others, such as Streptococcus pneumoniae and Haemophilus influenzae, take advantage of B-cell defects. Still others, such as Staphylococcus aureus and Shigella species, occur or persist for reasons that are unclear. Infections with organisms associated with hospitalization and medical procedures are also seen and should be anticipated. Among the infections taking advantage of T-cell defects, Pneumocystis carinii pneumonia is the most commonly diagnosed, but cytomegalovirus infection may be equally common. Disseminated Mycobacterium avium-intracellulare infection has been found in one half of our patients at postmortem examination. The retrovirus responsible for AIDS commonly infects the central nervous system, as does Toxoplasma gondii. Although candida infections are common, dissemination is uncommon. Many of the infections respond to appropriate therapy but tend to recur when treatment is stopped. Often treatment courses must be prolonged even beyond those used in other immunocompromised hosts.

The antibacterial activity of ofloxacin against Enterobacteriaceae, Pseudomonas aeruginosa, Haemophilus influenzae, Branhamella catarrhalis, and Neisseria gonorrhoeae was comparable to norfloxacin and enoxacin, and far exceeded the activity of pipemidic acid and nalidixic acid. The activity of ofloxacin was two to eight times less than that of ciprofloxacin. Ofloxacin was more active against Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, Acinetobacter spp., Legionella spp., and Bacteroides fragilis, than norfloxacin, enoxacin, pipemidic acid and nalidixic acid, and the activity of ofloxacin was comparable to that of ciprofloxacin. Ofloxacin was two to seven times more effective than norfloxacin in systemic infections in mice with S. aureus, Escherichia coli, Serratia marcescens and P. aeruginosa. Ofloxacin strongly inhibited DNA supercoiling activity of DNA gyrase purified from E. coli KL-16. There is a parallel relationship between antibacterial activity of ofloxacin and its inhibitory action against DNA gyrases from ofloxacin-susceptible and ofloxacin-resistant clinical isolates of E. coli. These results indicate that the high bactericidal action of ofloxacin and the related new quinolone agents can be explained by their potent inhibitory activities against DNA gyrase in bacterial cells.

In a double-blind study, 20 patients with peritonsillar abscesses were treated with 2 g phenoxymethylpenicillin b.i.d. for ten days together with needle aspiration, incision and daily drainage, and 20 patients were treated with 2 g phenoxymethylpenicillin b.i.d. and 0.8 g metronidazole b.i.d. for ten days together with needle aspiration, incision and daily drainage. Group A beta-hemolytic streptococci were isolated from pus in 20 of the patients with peritonsillar abscesses, in five of these together with indigenous oropharyngeal aerobic and anaerobic microorganisms. Pure anaerobic bacteria were found in nine abscesses, together with indigenous aerobic microorganisms in eight, and together with group A, C and G streptococci in five. In one patient heavily colonized with beta-lactamase-producing Staphylococcus aureus, Haemophilus parainfluenzae and Bacteroides, group A beta-streptococci failed to be eradicated. In the penicillin group, nine of 18 patients harboured beta-lactamase producing Bacteroides strains in the tonsils on the day of admission. On the third and tenth days of treatment all patients harboured beta-lactamase producing Bacteroides strains in the tonsils, while in the penicillin + metronidazole group, only one out of 17 patients still harboured beta-lactamase producing Bacteroides strains. None of the patients harboured beta-lactamase producing fusobacteria on the day of admission. In the penicillin group, however, beta-lactamase producing fusobacteria were recovered from three patients on the tenth day of treatment. No beta-lactamase producing fusobacteria were recovered from the penicillin + metronidazole group.(ABSTRACT TRUNCATED AT 250 WORDS)
