Prevalence of penicillin resistance has declined in the years since gonorrhea treatment with penicillin was discontinued. Fluoroquinolone-resistant N. gonorrhoeae infections continue to increase at a time when fluoroquinolone use has increased. Ongoing nationwide and local antimicrobial susceptibility monitoring is crucial to ensure appropriate treatment of gonorrhea.

Thirty-eight potentially pathogenic organisms were recovered in 36 (86%) of the children from the AMS group, and 40 were isolated from 26 (93%) of the children from the RMS group. The organisms isolated were Streptococcus pneumoniae (21 isolates), Haemophilus influenzae non-type b (17), Moraxella catarrhalis (15), Streptococcus pyogenes (13) and Staphylococcus aureus (12). Resistance to the eight antimicrobial agents used was found in 34 instances in the AMS group compared to 93 instances in the RMS group (P < 0.005). The difference between AMS and RMS was significant with S. pneumoniae resistance to amoxicillin (P < 0.0025), to co-amoxiclav (P < 0.0025), to trimethoprim-sulfamethoxazole (P < 0.05), to cefixime (P < 0.05), and to azithromycin (P < 0.05), and for H. influenzae to amoxicillin (P < 0.025).

There was a progressive emergence of small numbers of gonococci with cephalosporin MICs of 0.125-0.25 mg/L; these were not seen before 2005 but, for ceftriaxone and cefixime, respectively, accounted for 0.4% (95% confidence interval 0.2%-1.1%) and 2.8% (1.6%-4.8%) of the 1253 isolates collected in 2008; such MICs are 16-64 times the modal values for the species. Pharmacodynamic analysis was complicated by evidence that cephalosporins need a longer period with the free drug level above MIC than the 7-10 h required for penicillin G; nevertheless, pharmacodynamic analyses predict that failures with the standard 400 mg cefixime po and 250 mg ceftriaxone im regimens become likely around the present MIC maxima.

These results suggest that acute pyelonephritis in women could be successfully treated with a short-term course of 1 g of ceftriaxone on the first day followed by 400 mg of cefixime per day for 6 days. These positive results must be confirmed by a non-inferiority study.

Between March 2011 and February 2012, 201 specimens of Neisseria gonorrhoeae were consecutively obtained from men with symptoms of urethritis and women with symptons of cervicitis or were obtained during their initial consultation. The strains were tested using the disk diffusion method, and the minimum inhibitory concentrations of azithromycin, cefixime, ceftriaxone, ciprofloxacin, chloramphenicol, penicillin, tetracycline and spectinomycin were determined using the E-test.
To recommend a cost-effective approach for the management of acute male urethritis in the developing world, based on the findings of a theoretical study.

The bactericidal activity of cefotaxime against Escherichia coli, Klebsiella pneumoniae and Serratia marcescens, was compared with that of cefixime in an in vitro model simulating the human pharmacokinetics of these antibiotics. Kinetic parameters in this model were T1/2 = 1.3 h and Cmax = 45 mg/l for cefotaxime; T1/2 = 3.5 h and Cmax = 5 or 3.5 mg/l for cefixime. These parameters mimicked those obtained after a 1 g intravenous infusion of cefotaxime and an oral uptake of 0.4 or 0.2 g of cefixime, respectively. Both antibiotics demonstrated a strong bactericidal activity. Against Escherichia coli, the bactericidal effect of cefotaxime was slightly more rapid and more prolonged than that of cefixime: -5 log10 CFU/ml over 4 h vs -3 log10 CFU/ml over 8 h respectively. Against Klebsiella pneumoniae and Serratia marcescens, both drugs exhibited similar bactericidal activity despite different dosages and routes of administration: -2 to -3 log10 CFU/ml over 4 h.

Neisseria gonorrhoeae isolates gathered from the 3 cities differed significantly in the prevalence of tetracycline-resistant NG (P < 0.001) and NG treated with ceftriaxone with a minimum inhibitory concentration of 0.125 mg/L or higher (P < 0.001). The analysis of the combination of the 7 variable number of tandem repeats loci for all of the 244 isolates yielded 110 multiple-locus variable number tandem repeat analysis types falling into 5 clusters. Cluster III was associated with PPNG, whereas cluster II was associated with non-PPNG (P < 0.05) and NG treated with ceftriaxone with a minimum inhibitory concentration of 0.125 mg/L or higher (P < 0.05).

Empirical antimicrobial therapy should include coamoxiclav, nitrofurantoin, cefepime, and ceftazidime for females less than 65 years old in both H-T and H-A, cefalosporines, co-amoxiclav and nitrofurantoin in O-T UTIs; for females more than 65 years old, cefalosporines, aminoglicosides, and ciprofloxacin, in H-T and O-T UTIs. For H-A UTI in females more than 65 years as well as for all male patients antimicrobial susceptibility testing should be performed.
To clarify the clinical efficacy of a single oral 2 g dose of azithromycin extended-release for heterosexual male patients with urethritis, and the current antimicrobial sensitivity of Neisseria gonorrhoeae to azithromycin, a prospective clinical trial was conducted from 2011-2013. In patients with gonococcal urethritis, the eradication rate was 90.9% (30 of 33). The susceptibility rates of isolated Neisseria gonorrhoeae strains to ceftriaxone, spectinomycin, cefixime and azithromycin were 100%, 100%, 95.3% (41/43) and 37.2% (16/43), respectively. In the patients with nongonococcal urethritis, the eradication rate was 90.0% (45 of 50). The microbiological eradication rates for the pathogens were 90.9% (30/33) for Neisseria gonorrhoeae, 91.5% (43/47) for Chlamydia trachomatis, 71.4% (5/7) for Mycoplasma genitalium, and 100% (13/13) for Ureaplasma urealyticum. The main adverse event was diarrhea and its manifestation rate was 35.2% (32 of 120). The symptom of diarrhea was mostly temporary and resolved spontaneously. The conclusion was that the treatment regimen with a single oral 2 g dose of azithromycin extended-release would be effective for patients with urethritis. However, the antimicrobial susceptibilities of Neisseria gonorrhoeae and Mycoplasma genitalium should be carefully monitored because of possible treatment failure.

Loracarbef is a new oral antimicrobial of the carbacephem class with in vitro activity against the common pathogens associated with skin infections, otitis media, sinusitis, bronchopulmonary infections, and urinary tract infections. A review of the literature shows the following ranges for 90% minimum inhibitory concentration (MIC90) values (microgram/mL) against the organisms that commonly cause these illnesses: Streptococcus pneumoniae, 0.25-2.0; Moraxella (Branhamella) catarrhalis (beta-lactamase positive), 0.5-8.0; M. catarrhalis (beta-lactamase negative), 0.12-0.25; Haemophilus influenzae (beta-lactamase positive), 0.5-16.0; H. influenzae (beta-lactamase negative), 0.25-8.0; Escherichia coli, 2.0-25; Klebsiella pneumoniae, 0.25-8.0; Proteus mirabilis, 1.0-8.0; Streptococcus pyogenes, less than or equal to 0.06-1.0; Staphylococcus aureus (beta-lactamase positive), 8.0; S. aureus (beta-lactamase negative), 1.0-2.0. The in vitro activity of loracarbef against these common outpatient pathogens is similar to that of other oral antimicrobials such as cefaclor, cefuroxime axetil, cefixime, amoxicillin/clavulanate, and trimethoprim/sulfamethoxazole. The results of in vitro susceptibility tests with any antimicrobial, including loracarbef, are somewhat dependent on the specific test method that is employed in the laboratory. This is particularly true with H. influenzae. Furthermore, the results of loracarbef susceptibility tests are of uncertain value in predicting therapeutic outcome.
