The efficacy and safety of ciprofloxacin in the treatment of 68 episodes of bacteremia were studied. Patients were treated intravenously (30 cases), orally (13 cases), or with sequential intravenous/oral therapy (25 cases). Intravenous doses ranged from 200 to 400 mg per day and oral doses ranged from 1,000 to 1,500 mg per day. According to the criteria of McCabe and Jackson, 39 cases had nonfatal and 29 had ultimately fatal underlying diseases. The clinical condition of patients at the start of therapy was critical or poor in 40 cases and fair or good in 28. Sixty-four of the 68 episodes of bacteremia were monomicrobial and the remaining four were polymicrobial. The causative micro-organisms were: Escherichia coli (18 episodes), Pseudomonas aeruginosa (13 episodes), Acinetobacter sp. (10 episodes), Salmonella sp. (seven episodes), Enterobacter sp. (six episodes), Proteus sp. (four episodes), Serratia sp. (four episodes), Haemophilus influenzae (three episodes), Klebsiella sp. (three episodes), Staphylococcus aureus (2 episodes), and Morganella morganii (two episodes). Overall clinical efficacy of ciprofloxacin was 94 percent (64 of 68 patients). Bacteremia persisted in four patients (failure rate of 6 percent). Five organisms persisted: Acinetobacter sp. (two patients), P. aeruginosa (one patient), Enterobacter sp. (one patient), and Serratia sp. (one patient). Side effects were phlebitis associated with intravenous administration (four cases), dizziness (four cases), and superinfection (six cases). Superinfecting organisms and sites were as follows: Enterococcus faecalis, wound (2 cases); Candida sp., urinary tract infection (one case); Acinetobacter anitratus (ciprofloxacin resistant), urinary tract infection (one case); Staphylococcus epidermidis, blood (one case); and Clostridium perfringens, blood (one case). Ciprofloxacin administered either intravenously, orally, or intravenously followed by the oral route is effective therapy in the treatment of severe bacteremic infections.

Ciprofloxacin is a new quinolone antimicrobial agent with activity against a broad spectrum of gram-negative and gram-positive organisms, including Pseudomonas aeruginosa and methicillin-resistant strains of staphylococci. The efficacy and safety results of 80 clinical studies of the oral form of ciprofloxacin are reported. Drug safety was assessed in 2236 courses in 2203 adult patients treated primarily in the United States. Data from 1676 courses were suitable for analysis of drug efficacy. The unit dose for most patients ranged from 250 mg to 750 mg (median, 500 mg), usually given every 12 hours. The duration of treatment ranged from 3 to 231 days (median, 10 days). Predominant among 1722 infections were those of the urinary tract (43%), skin structures (29%), and respiratory tract (19%); the remainder were bone and joint infections (5%), bacteremias (2%), and intra-abdominal (1%), gastrointestinal (1%), and pelvic infections (less than 1%). Signs and symptoms of infection resolved in 79% of all cases; a further 15% improved, and 5% failed to improve. Pathogens were eradicated in 89% of urinary tract infections and persisted in 5%; 80% of patients still had sterile urine at the 3-to 6-week follow-up. In 81% of nonurinary tract infections, pathogens were eradicated; they persisted in 11%, and superinfection occurred in less than 5%. After treatment, 89% of the 2253 causative organisms were eradicated and 2% were reduced to clinically insignificant counts; 8% persisted. Of 411 isolates of P. aeruginosa, 77% were eradicated, as were 97% of 421 Escherichia coli and 80% of 248 Staphylococcus aureus isolates. Also eradicated were 95% of 166 Klebsiella, 96% of 139 Proteus mirabilis, 100% of 20 other Proteus, 94% of 123 Enterobacter, 100% of 68 Haemophilus influenzae, 96% of 49 Citrobacter, 89% of 45 Serratia, 95% of 41 Streptococcus pneumoniae, 91% of 43 Salmonella, 100% of 38 Morganella morganii, and 100% of 35 Providencia isolates. Adverse reactions were judged probably or possibly drug-related in 14.8% of courses; drug treatment had to be stopped prematurely in 3.5%. The most frequent reactions were gastrointestinal complaints (chiefly nausea, diarrhea, and vomiting), metabolic disorders (elevated SGOT, SGPT, serum creatinine, or blood urea nitrogen), and nervous system effects (dizziness, light-headedness, restlessness, tremor, and headache). Crystalluria, judged to be related to ciprofloxacin, occurred in two patients.(ABSTRACT TRUNCATED AT 400 WORDS)

28 patients with urinary tract infections (UTI) were treated with norfloxacin 2 X 400 mg daily for 9 days. 14 of these patients had complicated UTI (stones, obstruction). The main pathogens were E. coli and Proteus mirabilis. On the third day of treatment all bacteria were eradicated. One week after therapy all patients with uncomplicated UTI were cured and, likewise, 9 of 14 with complicated UTI. There was no laboratory evidence of adverse effects. 6 patients reported only mild side effects such as epigastric pain, dizziness and pruritus, which did not necessitate discontinuation of norfloxacin. Norfloxacin appears to be safe and effective in the treatment of UTI.

Augmentin, a formulation of amoxycillin trihydrate 250 mg and sodium clavulanate 125 mg per tablet (A-CS) (Augmentin; Beecham), was used in treating 29 episodes of urinary tract infection occurring in 26 patients admitted to the Spinal Unit of the H. F. Verwoerd Hospital, Pretoria. Patients who had a urinary bacterial cell count of more than 105 of the same amoxycillin-resistant organism before and after the oral administration of amoxycillin 500 mg 3 times a day for 48 hours, received 2 A-CS 375 mg tablets orally, 3 times a day at the start if a meal for 5 days. The 29 strains of amoxycillin-resistant organisms treated in this study were: Escherichia coli (11), Klebsiella pneumoniae (11), Proteus mirabilis (4), Enterobacter cloacae (2), and Staphylococcus epidermidis (1). The bacteriological success rate 24 hours after therapy was 100% and 8 days after therapy 69%, dependent on patient management. In patients on free drainage and managed with condoms a bacteriological success rate of 55,5% was recorded and in patients managed by intermittent catheterization a bacteriological success rate of 75% was recorded. Side-effects were minimal; 1 patient complained of dizziness and no instances of nausea or vomiting were reported. Haematological, renal and hepatic monitoring before and after A-CS-therapy revealed no drug-related toxicity.

This study enrolled patients with complicated urinary tract infections (UTIs) in a trial to determine the efficacy and safety of sequential therapy with intravenous fleroxacin (first 3 days) followed by oral fleroxacin, for a total course of 7-14 days, both administered at a dosage of 400 mg once a day. We enrolled 68 patients with complicated UTIs or acute pyelonephritis, 32 of whom were evaluable for bacteriologic and clinical efficacy. The pathogens isolated included Escherichia coli, 15; enterococci, 9; miscellaneous, 15. Intravenous fleroxacin was given for a mean of 3.2 days, followed by oral fleroxacin for a mean of 5.3 days. A total of 27 patients were clinically cured (84%), two improved, and three failed. A total of 26 patients were bacteriologically cured (81%), and six failed (19%). The bacteria that were not eradicated included enterococci, 4; Staphylococcus epidermidis, 1; and Pseudomonas species, 1. One enterococcal isolate became resistant to fleroxacin. Four patients were bacteremic (E. coli, 3; Proteus mirabilis, 1); the pathogen was eradicated in all cases. Two patients developed urinary enterococcal superinfections. A total of 12 patients experienced 16 adverse reactions remotely, possibly, or probably related to fleroxacin (insomnia, 3; dizziness, 2; miscellaneous, 11). One patient had a grand mal seizure after aspirating gastric contents; the seizure was thought to be only remotely related to the study drug. Fleroxacin was discontinued in two patients because of adverse effects (phlebitis at intravenous access site, 1; anxiety and insomnia, 1). Only minor and asymptomatic laboratory abnormalities were observed. All clinical and laboratory abnormalities resolved with discontinuation of the study drug. Fleroxacin is a safe and effective antibiotic for sequential intravenous and oral treatment of acute pyelonephritis and complicated UTIs. Enterococci may be problematic pathogens, as reported with other fluoroquinolones.

In a multicenter study the efficacy and safety of oral fleroxacin at 400 mg once a day and amoxicillin at 500 mg three times daily for 7 days were compared for the treatment of patients with acute bacterial exacerbations of chronic bronchitis due to drug-susceptible bacteria. A total of 194 patients were enrolled, 102 in the fleroxacin group and 92 in the amoxicillin group. Of those enrolled, 22 in the fleroxacin group and 30 (29 for clinical efficacy) in the amoxicillin group were included in the efficacy analysis. All were included in the safety analysis. Clinical success was noted in 21 (95%) of 22 fleroxacin-treated patients and 22 (76%) of 29 amoxicillin-treated patients. Bacteriologic cure was obtained in 21 (95%) of 22 of the fleroxacin group and 18 (60%) of 30 of the amoxicillin group. One Haemophilus parainfluenzae strain persisted with fleroxacin. Persisting organisms with amoxicillin included Haemophilus influenzae (four), Haemophilus parainfluenzae (three), Escherichia coli (two), Streptococcus pneumoniae (one), Neisseria species (one), and Proteus mirabilis (one). Adverse events were reported by 41% of 102 patients receiving fleroxacin and 15% of 92 patients receiving amoxicillin. Insomnia, dizziness, and nausea occurred more frequently with fleroxacin. Fleroxacin may be indicated for the treatment of acute bacterial infection in chronic bronchitis known to be due to Haemophilus species and Moraxella catarrhalis. The 92% incidence of resistance among the S. pneumoniae isolates recovered from all enrolled patients suggests that fleroxacin may not be useful for such infections.
