A total of 150 patients completed the study. Of the 119 patients, 70 (58.8%) were cured from H. pylori, and in 49 (41.2%) of patients, treatment of H. pylori was unsuccessful. All 31 controls remained H. pylori-positive. At the final endoscopy, erosive esophagitis was found in 19 (12.7%) patients. Erosive esophagitis developed in 8 (11.4%) successfully eradicated patients, in 9 (18.4%) unsuccessfully treated patients, and in 2 (6.5%) controls (P>0.05 comparing the groups). Multivariate logistic regression analysis revealed 3 factors at baseline, which were significant (P<0.05) in predicting the occurrence of erosive esophagitis: age more than 43 years (OR, 4.96; 95% CI, 1.47-16.71), nonerosive gastroesophageal reflux disease (OR, 3.96; 95% CI, 1.34-11.68), and smoking (OR, 3.17; 95% CI, 1.01-9.17).
The efficacy and safety of azithromycin and clarithromycin were compared in an open multicentre study involving 380 adult patients with acute otitis media, acute sinusitis, or acute streptococcal pharyngitis or tonsillitis. Patients were assigned randomly to receive azithromycin as a single dose of 500 mg daily for three days, or clarithromycin 250 mg bid for ten days. Overall clinical efficacy was found to be similar in each treatment group at day 10-14, with a satisfactory outcome (cured or improved) in 95% of azithromycin and 96% of clarithromycin patients. Bacteriological efficacy was also similar, with eradication of the pathogen in 94% and 95% of isolates, respectively, in the azithromycin and clarithromycin groups. In otitis media, a satisfactory clinical response was seen in 97% of patients in each treatment group. Azithromycin therapy resulted in a clinical response rate of 93% in sinusitis patients, with bacteriological eradication in 93% of patients. Two patients (who were cured clinically) had persistent pathogens. Similarly, clarithromycin achieved clinical response and bacteriological eradication in 95% and 92% of sinusitis patients, respectively. Pathogens persisted in two patients with clinical cure, and in one case of clinical failure. In pharyngitis or tonsillitis, Streptococcus pyogenes was eradicated successfully in 95% of patients in both groups, and the clinical success rates were 96% and 97% for azithromycin and clarithromycin, respectively. No case of clinical failure was associated with persistence of S. pyogenes infection. At the follow-up assessment of this diagnosis group, reinfection had occurred in three (8%) azithromycin patients and one (3%) clarithromycin patient, and all but one patient remained asymptomatic. Both drugs were well-tolerated, with 8.4% of patients on azithromycin and 7.4% on clarithromycin reporting adverse events, mainly gastrointestinal. It was concluded that a three-day course of azithromycin was as effective and well-tolerated as a ten-day course of clarithromycin in adults with acute upper respiratory tract infections.

Several of the interventions were found to have some benefit at preventing or reducing the severity of mucositis associated with cancer treatment. The strength of the evidence was variable and implications for practice include consideration that benefits may be specific for certain cancer types hat benefits may be specific for certain cancer types and treatment. There is a need for well designed and conducted trials with sufficient numbers of participants to perform subgroup analyses by type of disease and chemotherapeutic agent.

Compared with the control group, patients co-prescribed clarithromycin and a statin not metabolized by CYP3A4 were at increased risk of hospital admission with acute kidney injury (adjusted relative risk [RR] 1.65, 95% confidence interval [CI] 1.31 to 2.09), admission with hyperkalemia (adjusted RR 2.17, 95% CI 1.22 to 3.86) and all-cause mortality (adjusted RR 1.43, 95% CI 1.15 to 1.76). The adjusted RR for admission with rhabdomyolysis was 2.27 (95% CI 0.86 to 5.96). The absolute increase in risk for each outcome was small and likely below 1%, even after we considered the insensitivity of some hospital database codes.

Clarithromycin (TE-031, A-56268) is a new 14-membered ring macrolide antibiotic developed by Taisho Pharmaceutical Co., Ltd. TE-031 has a methoxy group at position 6 in its structure. In the present study, we carried out laboratory and clinical investigations on TE-031 in the field of pediatrics. The obtained results are summarized as follows. The antibacterial activity of TE-031 was investigated against 16 clinically isolated strains of Streptococcus pyogenes, Staphylococcus aureus, Haemophilus influenzae, Bordetella pertussis and Campylobacter jejuni. TE-031 showed antibacterial activity comparable to erythromycin. The pattern of changes in TE-031 concentrations in the blood after administration was investigated. In subjects administered the granular preparation of TE-031, Cmax values were 0.64 micrograms/ml in 1 subject given a 5 mg/kg dosage, and 5.94 and 9.02 micrograms/ml in 2 subjects administered with 10 mg/kg. The tablet form of TE-031 was administered to 3 subjects at 5 mg/kg, and Cmax values were 2.09-3.92 micrograms/ml, while T 1/2 values were in a range of 2.9-3.8 hours. When drug concentrations in the urine were investigated, it was found that 6-hour recovery rates were 9.9% (dose: 5 mg/kg) and 53.4% (dose: 10 mg/kg) in the subjects administered the granular form, whereas recovery rates averaged 36.8% in the tablet-administered subjects. In the clinical trial, TE-031 was administered in 2-3 doses/day for 2-18 days. In cases given the granular form, dosages were 12-38 mg/kg/day, while tablets were administered at 12-29 mg/kg/day. The overall clinical efficacy rate was 92.8%, i.e., the drug was effective in 64 of 69 patients. TE-031 was ineffective in 1 case of otitis media, but efficacious in 10 of 10 (100%) cases of upper respiratory infection, 15 of 18 (83.3%) cases of bronchitis and pneumonia, 5 of 6 (83.3%) cases of pertussis, 13 of 13 (100%) cases of mycoplasmal pneumonia, 4 of 4 (100%) cases of Chlamydia psittaci pneumonia, 16 of 16 (100%) cases of gastroenteritis (including 15 cases of Campylobacter gastroenteritis), and 1 (100%) case of impetigo. In bacteriological studies conducted on the patients, the overall elimination rate was 93.1%, i.e., bacterial elimination was obtained in 27 of 29 cases. TE-031 showed especially good bacteriological efficacy (100%) against C. jejuni and B. pertussis, which were eliminated from all of 15 and 2 cases examined, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)

To clarify the discrepancy between increasing resistance and conservative clinical effects of macrolides on macrolide-resistant Streptococcus pneumoniae, the authors evaluated the effects of sub-minimum inhibitory concentrations of macrolides on pneumolysin. In vitro, S. pneumoniae was incubated with 1, 2 and 4 microg.mL(-1) of clarithromycin (CLR) and azithromycin (AZM) for 8 h. Western blot analysis and haemolytic assay were performed to examine the production and activities of pneumolysin. In vivo, mice were infected with S. pneumoniae intra-nasally and treated with CLR (40 or 200 mg.kg(-1) twice daily) or AZM (40 or 200 mg.kg(-1) once daily) orally for 7 days. After 72 h post-infection, western blot analysis was performed to examine pneumolysin production in lungs. Survival rates were observed for 10 days. In vitro, every concentration of macrolide inhibited pneumolysin production more than the control. CLR (2 and 4 microg.mL(-1)) and AZM (4 microg.mL(-1)) reduced the pneumolysin activities more than the control. In vivo, macrolides (200 mg.kg(-1)) reduced pneumolysin in murine lungs more than the control. CLR (40 and 200 mg.kg(-1)) and AZM (200 mg.kg(-1)) improved the survival rates more than the control. The study results show that sub-minimum inhibitory concentrations of macrolides reduced pneumolysin. This might be related to the effectiveness of macrolides against pneumonia caused by high-level macrolide-resistant Streptococcus pneumoniae. Further investigations are necessary to evaluate the effects of macrolides on macrolide-resistant Streptococcus pneumoniae.

Helicobacter pylori (HP) infection is the commonest chronic bacterial infection of man. Most gastroduodenal ulcers are due to HP infection. In addition, HP infection is considered to be the main aetiological factor of gastric carcinogenesis. For more than 30 years antibiotic therapy has been very effective in eradicating HP. Both antibiotic resistance and insufficient adherence to treatment threaten the efficacy of eradication therapy. Secondary antimicrobial resistance rates of H. pylori as published by the German National Reference Centre show the drastic increase of antibiotic resistance. If the initial standard triple therapy fails, the secondary resistances rise up to about 62 % for metronidazole, 66 % for clarithromycin and 21 % for quinolones. Therefore we should aim at a highly effective first-line treatment strategy that takes into account any risk of antibiotic resistance in an individual patient. Adherence to therapy and eradication efficacy will have to be monitored even more carefully in the future.
