The efficacy and safety of orally administered clarithromycin and erythromycin in the treatment of community-acquired pneumonia were assessed in a multicenter, double-blind, randomized study. Two hundred sixty-eight patients were randomized to receive either clarithromycin, 250 mg twice a day, or erythromycin stearate, 500 mg 4 times a day, for 7 to 14 days. Efficacy was evaluable in 173 patien...
This study aims to evaluate Helicobacter pylori with clarithromycin resistant genotypes in Manisa region, Turkey. Two hundred patients, who received diagnosis of Helicobacter pylori infection histopathologically, were included. The sex, age and endoscopy indications of the patients were recorded. Polymerase chain reaction method was applied to determine the clarithromycin resistance rate and re...
BACKGROUND Periostin is a biomarker indicating the presence of type 2 inflammation and submucosal fibrosis; serum periostin levels have been associated with asthma severity. Macrolides have immunomodulatory effects and are considered a potential therapy for patients with severe asthma. Therefore, we investigated whether macrolides can also modulate pulmonary periostin production. METHODS Usin...
background: clarithromycin resistance in helicbacter pylori has been found to be associated with point mutations in 23s rrna gene leads to reduced affinity of the antibiotic to its ribosomal target or changing the site of methylation. the aim of this study was to determine the most important point mutations in 23s rrna gene in h. pylori that are closely related to clarith-romycin resistance amo...
background helicobacter pylori eradication with clarithromycin is more expensive than with azithromycin. objectives this study aimed to compare the effectiveness of these two antibiotics in eradicating h. pylori in hemodialysis (hd) patients. patients and methods this is a prospective, randomized, double-blinded clinical trial analysis of hd patients. patients who had dyspepsia and showed posit...
BACKGROUND Therapy for Helicobacter pylori is generally empiric despite the fact that resistance to metronidazole and clarithromycin compromise therapeutic efficacy. The aim of this study was to aid clinicians in choosing a course of therapy for H pylori infection in the United States. METHODS The frequency of primary clarithromycin and metronidazole resistance among H pylori isolated from pa...
The macrolide antibiotics azithromycin and clarithromycin are large molecular weight compounds that exhibit moderate to excellent oral bioavailability in preclinical species and humans. Previous concomitant dosing studies in rats using rifamycin SV, a general organic anion-transporting polypeptide (OATP) inhibitor, suggested that the high oral absorption of azithromycin and clarithromycin may b...
Resistance to clarithromycin in breakthrough Mycobacterium avium complex (MAC) isolates typically occurs 3 to 4 months after the initiation of monotherapy in bacteremic AIDS patients. It has been suggested that continuation of clarithromycin therapy still results in clinical and microbiological improvement. To study this paradox, C57BL/6 beige mice were infected with a clarithromycin-resistant ...
The macrolide antibiotic clarithromycin can enhance central nervous system excitability, possibly by antagonism of GABA-A receptors. Enhancement of GABA signaling has recently been demonstrated in a significant proportion of patients with central nervous system hypersomnias, so we sought to determine whether clarithromycin might provide symptomatic benefit in these patients. We performed a retr...
OBJECTIVE To evaluate the clinical efficacy, safety, and tolerability of clarithromycin in patients with rheumatoid arthritis. RESEARCH DESIGN AND METHODS This was a 6-month, monocenter, randomized, double-blind, placebo-controlled study. A total of 81 patients with early rheumatoid arthritis were treated with either once-daily oral clarithromycin (500 mg) or daily oral placebo for 6 months. ...
