Since April 2011, a dosage adjustment program has been implemented at Gifu Municipal Hospital. In this program, upon receiving a prescription for renally eliminated drugs, pharmacists verify patients' serum creatinine concentrations by using a computerized medical record system to evaluate the patient's kidney function and suggest the appropriate dosage to doctors, if necessary. In our study, we used questionnaires that were administered to pharmacists and doctors at the hospital to investigate their respective working times and the cost of the program, in order to comprehensively analyze the clinical resource costs of the hospital and evaluate the economic burden of the program for levofloxacin. In addition, we studied the pharmacists' and doctors' attitudes toward the program and the circumstances of prescriptions for patients with renal dysfunction. The questionnaire comprised items such as time required for the program; attitude toward the program, including satisfaction; and attitude toward the circumstances of prescriptions for patients with renal dysfunction. The pharmacists' and doctors' working times and cost of the program were obtained from the questionnaire responses. For cost estimation, we used data from this study as well as those of our previous study that suggested that the levofloxacin program was economically beneficial. Furthermore, their attitudes toward the program and circumstances of prescriptions for patients with renal dysfunction were clarified. Regarding the pharmacists' tasks and interventions, we need to not only investigate attitudes toward them but also perform a cost analysis by the method of the economic evaluation of the medical techniques used in our study.
The median age of the patients was 34.5 (16-75) years. The baseline clinical and MRI findings were similar between the two groups. At 6 months, 13 out of 60 (21.7%) patients in the levofloxacin arm and 23 out of 60 (38.3%) patients in the rifampicin arm had died (P = 0.07). On Cox regression analysis, survival in the levofloxacin group was significantly better than in the rifampicin group (hazard ratio 2.13, 95% CI 1.04-4.34, P = 0.04). The functional outcome (P = 0.47) was, however, not significantly different between the two groups. On intention-to-treat analysis, 10 out of 47 (21.3%) in the levofloxacin arm and 5 out of 37 (13.5%) in the rifampicin arm had poor recovery. Repeat MRI findings did not differ between the groups. Levofloxacin was discontinued more frequently than rifampicin due to SAEs (16 versus 4, P = 0.01).

Although fluoroquinolones are used widely in the treatment of various infectious diseases, some of the drugs are known to cause hypoglycemia as a side-effect. We have investigated the effects of three fluoroquinolone derivatives, levofloxacin, gatifloxacin, and temafloxacin, on insulin secretion and pancreatic beta-cell ATP-sensitive K(+) channel (K(ATP) channel) activity. While levofloxacin had only a small effect on insulin secretion and K(ATP) currents, gatifloxacin and temafloxacin stimulated insulin secretion and inhibited K(ATP) channel currents in a dose-dependent manner. We also determined the site of action of gatifloxacin and temafloxacin on the K(ATP) channel. In a reconstituted system, gatifloxacin and temafloxacin inhibited Kir6.2 Delta C26 channels, which function in the absence of the SUR subunit, indicating direct action of the drugs on the Kir6.2 subunits. These results suggest that stimulation of insulin secretion by inhibition of pancreatic beta-cell K(ATP) channels underlies the hypoglycemia caused by certain fluoroquinolones.

A 70 year-old woman was prescribed of levofloxacin and ceftriaxone for acute bronchitis. On the seventh day of administration she was hospitalized with a dry cough and a decreased platelet count(2.1 x 10(4)/microliter). However, bleeding tendency was not seen. So, we changed anticoagulants with citric acid and heparin from EDTA, and measured platelet count because we suspected pseudothrombocytopenia(PTCP), then platelet count became elevated (respectively, 12.5 x 10(4)/microliter and 15.0 x 10(4)/microliter). In addition, platelet associated IgG increased to 309.3 ng/10(7) cells. Based on drug lymphocyte stimulation test, she was diagnosed as having antibiotic-induced PTCP, especially as she had no history of thrombocytopenia. PTCP should be considered when thrombocytopenia occurs during antibiotic treatment.

The in vitro activities of seven quinolones and the sequences of the quinolone resistance-determining regions (QRDR) in the A and B subunits of DNA gyrase were determined for 14 mycobacterial species. On the basis of quinolone activity, quinolones were arranged from that with the greatest to that with the least activity as follows: sparfloxacin, levofloxacin, ciprofloxacin, ofloxacin, pefloxacin, flumequine, and nalidixic acid. Based on MICs, the species could be organized into three groups: resistant (Mycobacterium avium, M. intracellulare, M. marinum, M. chelonae, M. abscessus [ofloxacin MICs, >/=8 microg/ml]), moderately susceptible (M. tuberculosis, M. bovis BCG, M. kansasii, M. leprae, M. fortuitum third biovariant, M. smegmatis [ofloxacin MICs, 0.5 to 1 microg/ml]), and susceptible (M. fortuitum, M. peregrinum, M. aurum [ofloxacin MICs, =0.25 microg/ml]). Peptide sequences of the QRDR of GyrB were identical in all the species, including the amino acids at the three positions known to be involved in acquired resistance to quinolone, i.e., 426 (Asp), 447 (Arg), and 464 (Asn) (numbering system used for Escherichia coli). The last two residues could be involved in the overall low level of susceptibility of mycobacteria to quinolones since they differ from those found in the very susceptible E. coli (Lys-447 and Ser-464) but are identical to those found in the less susceptible Staphylococcus aureus and Streptococcus pneumoniae. Peptide sequences of the QRDR of GyrA were identical in all the species, except for the amino acid at position 83, which was an alanine in the two less susceptible groups and a serine in the most susceptible one, as in E. coli, suggesting that this amino acid is involved in the observed differences of quinolone susceptibility within the Mycobacterium genus.
1. Minimum inhibitory concentrations (MICs) of levofloxacin (LVFX, DR-3355), ofloxacin (OFLX), tosufloxacin (TFLX), norfloxacin (NFLX) were determined, with an inoculum size of 10(6) cfu/ml, against 122 strains of Staphylococcus aureus isolated from lesions of skin infections. LVFX showed most frequent MIC values of 0.20 micrograms/ml. OFLX, TFLX, and NFLX showed most frequent MIC values of 0.39 micrograms/ml, less than or equal to 0.05 micrograms/ml and 0.78 micrograms/ml, respectively. 2. Serum and skin levels of LVFX after oral administration (10 mg/kg, fasting) were determined in rats. Serum levels were 1.79, 1.29, 0.60, 0.43 and 0.18 micrograms/ml, and corresponding skin levels were 1.63, 1.77, 1.04, 0.87 and 0.64 micrograms/g (wet weight) at 0.5, 1, 2, 4 and 8 hours after administration (n = 5), respectively. 3. LVFX was used clinically in 43 cases at doses of 200-300 mg divided into 2 or 3 doses, and evaluated for final overall clinical efficacy in 41 cases. Cure was observed in 21 cases, remarkable improvement in 13 cases, improvement in 4 cases, unchanged in 1 case, aggravation in 1 case, and remarkable aggravation in 1 case. Diarrhea was observed in 2 cases, diffuse erythema with feverishness in 1 case and slight dyspnea in 1 case. Transient slight eosinophilia, elevation of Al-P, anemia and leukopenia were observed.
This study demonstrates successful implementation of a guideline for levofloxacin prophylaxis during leech therapy. Following its introduction, no Aeromonas species related to the use of leeches were isolated as compared to 8.5 % in the baseline period.

A 52-year-old Japanese woman was referred to our Institute because of Helicobacter pylori(H. pylori)-positive gastric mucosa-associated lymphoid tissue(MALT)lymphoma. Since she had a penicillin allergy, we could not eradicate H. pylori using the standard triple therapy including amoxicillin. Additionally, H. pylori was resistant to both clarithromycin and metronidazole. So she was treated with minomycin (MINO), levofloxacin (LVFX), and rabeprazole (RPZ) based on a drug sensitivity test. MINO+LVFX+RPZ appear to be a promising, appropriate, and well-tolerated eradication regimen for H. pylori demonstrating resistance to both clarithromycin and metronidazole, and for patients who are allergic to penicillin.
The new fluoroquinolones offer advantages over ciprofloxacin in terms of improved in vitro activity and pharmacokinetics. Whether these advantages translate into improved clinical outcomes is presently unknown. The new fluoroquinolones have the potential to emerge as important therapeutic agents in the treatment of respiratory tract and genitourinary tract infections.
