    ABSTRACT: Thirty adults (mean age, 52 years) were enrolled in a randomized, comparative trial of oral ciprofloxacin (750 mg twice daily) and other antimicrobial therapies. Etiologic agents included Enterobacteriaceae (18 isolates), Pseudomonas aeruginosa (16 isolates), and Staphylococcus aureus (four isolates). Seven of 14 (50 percent) ciprofloxacin-treated infections are cured at up to 13 months follow-up and three infections appear improved. Treatment failure or relapse has occurred in four patients. Sixteen patients received other antimicrobial therapy and 11 patients (65 percent) remain without infection and have healed wounds, with follow-up from one to 13 months. One patient has had a relapse, while improvement is apparent in four patients. Complications that occurred in this group included drug-related neutropenia (two patients), diarrhea (two patients), drug allergy (one patient), and catheter-related staphylococcal cellulitis (one patient). Oral ciprofloxacin therapy for chronic osteomyelitis caused by susceptible organisms appears to be as effective as other antimicrobial therapies.

    ABSTRACT: We treated 52 patients with orally administered ciprofloxacin. In this study of 34 men and 18 women who completed therapy and who could be evaluated, there were 29 patients with nonhematogenous osteomyelitis, 20 patients with skin or soft-tissue infections, and 3 patients with joint infections. During the study, 92 isolates of pathogenic facultative aerobic bacteria, including 37 members of the family Enterobacteriaceae, 30 Staphylococcus aureus isolates, and 21 Pseudomonas aeruginosa isolates, were recovered, and 88 (96%) of the isolates were found to be susceptible to ciprofloxacin. Of the 29 patients with osteomyelitis, 14 have not experienced relapse after a follow-up of at least 1 year. Overall, 61% of infections were resolved, as judged by both clinical and microbiological criteria, during therapy. One patient developed Streptococcus salivarius sepsis during ciprofloxacin therapy, and one patient developed a rash which required discontinuation of ciprofloxacin. Otherwise, there were no serious reactions or complications.

    ABSTRACT: Seventy hospitalized patients with upper urinary tract infections were treated with cefoperazone (2 gm) and sulbactam (1 gm) every 12 hours for three or more days. All but six patients also received vitamin K. Forty of the 70 patients (57%) were cured of infection at one week after treatment, 13 relapsed, 11 had reinfections, and six were lost to follow-up. There were no treatment failures. Escherichia coli was the predominant pathogen (62% of isolates). Overall there was 15% resistance to cefoperazone and all resistant isolates were susceptible to the combination of agents. Synergy was demonstrated in 26% of isolates. One uroseptic patient who had an organism resistant to both study agents, but susceptible to the combination, was cured. Two of six patients who did not receive vitamin K demonstrated abnormal coagulation patterns and one had an associated major bleeding complication. Although 12 of 64 (19%) patients who received vitamin K had at least one coagulation abnormality, there were no significant bleeding complications in this group.

    ABSTRACT: Sixty-two patients who had postpartum endometritis were treated with clindamycin in combination with either aztreonam or the aminoglycoside gentamicin. Currently, the combination of clindamycin and an aminoglycoside constitutes a treatment of choice for this condition. Our results suggest that aztreonam can be substituted for an aminoglycoside in the treatment of postpartum endometritis with similar clinical outcomes.

    ABSTRACT: We evaluated the following five treatment regimens for acute cystitis in nonpregnant women: cefadroxil, 1,000 mg single-dose; cefadroxil, 500 mg twice a day for three days; cefadroxil, 500 mg twice a day for seven days; trimethoprim-sulfamethoxazole (TMP-SMZ), 320–1,600 mg single-dose, and TMP-SMZ, 160–800 mg twice a day for three days. At four weeks after the end of treatment, 25070, 58070, 70%, 65%, and 88% of patients, respectively, remained cured of infection. The results indicated that three-day treatment (1) might improve cure rates (over single-dose), (2) would reduce incidence of relapse (vs. single-dose), and (3) may be as curative as seven-day treatment. The results of the antibody-coated bacteria test did not predict treatment failure or relapse.

    ABSTRACT: Nineteen patients with community- or hospital-acquired gram-negative pneumonia were treated with aztreonam. Other gram-negative antibiotics were withheld. Thirteen patients (68 percent) had clinical cures and 15 (79 percent) had microbiologic cures with aztreonam. No adverse reactions or drug toxicity occurred in this population.

    ABSTRACT: Twenty-three males with the clinical diagnosis of chronic prostatitis were evaluated for a bacterial etiology by the Stamey and Meares method. In addition, 16 patients, regardless of culture results, were placed on either cefadroxil or oral carbenicillin antimicrobial therapy. Culture results identified only four (17%) of 23 patients with bacterial prostatitis: coagulase-negative Staphylococcus (2), Enterobocter agglomerons (1), and Haemophilus parainfluenzae, and coagulase-negative Staphylococcus (1). Four of seven patients who received oral carbenicillin and three of nine patients who received cefadroxil reported symptomatic relief. This study did not identify a common etiology for chronic prostatitis or a consistently effective antimicrobial treatment. Rather, we observed that the etiologic agent in most cases of chronic prostatitis (83%) could not be identified by routine bacteriologic culture. Future research efforts in chronic prostatitis must address not only treatment regimens but expand the search for etiologic agents.

    ABSTRACT: Aztreonam (SQ 26,776) is the first parenteral monobactam agent to be used in patient trials. The agent has significant activity in vitro against facultative aerobic gram-negative bacteria but not against gram-positive or anaerobic bacteria. Aztreonam was used for a year to treat 106 hospitalized patients with a total of 131 documented gram-negative infections. Important exclusion criteria included granulocytopenia, hyperbilirubinemia, meningitis, patients less than 13 years of age, pregnancy, and history of anaphylaxis to penicillin. In this study of 35 men and 71 women, there were 67 cases of pyelonephritis (25% bacteremic), 19 of pneumonia (16% bacteremic), 10 of skin or soft-tissue infections, 9 cases of osteomyelitis, and 6 cases of postpartum endometritis. During the study period, 159 facultative aerobic gram-negative bacteria were tested for aztreonam susceptibility, and 144 (91%) were found to be susceptible. Eighty percent of infections were cured by both clinical and microbiological criteria and each of the other 26 infections showed clinical improvement. Eradication of the infecting organism was achieved in 89% of infections without adverse reaction or drug toxicity.
