Evidence for Chlamydia pneumoniae infection in steroid-dependent asthma.

BACKGROUND: Chlamydia pneumoniae is an obligate intracellular respiratory pathogen capable of persistent infection. Seroepidemiologic studies and the results of open-label antimicrobial treatment of patients with non-steroid-dependent asthma have suggested a potential role for C. pneumoniae in asthma. OBJECTIVE: To evaluate the results of antimicrobial treatment in patients with uncontrolled steroid-dependent asthma and serologic evidence suggesting C. pneumoniae infection. METHODS: Three nonsmoking asthmatic patients (aged 13 to 65 years) whose symptoms remained poorly controlled despite daily administration of inhaled and oral steroid (10 to 40 mg/d). All met serologic criteria for current or recent C. pneumoniae infection. RESULTS: After prolonged treatment (6 to 16 weeks) with clarithromycin or azithromycin all three patients were able to discontinue oral steroids. All three patients have remained well controlled with inhaled antiasthma therapy only during 3 to 24 months of postantibiotic therapy observation. CONCLUSIONS: In adolescent and adult asthmatic patients, Chlamydia pneumoniae infection may contribute to symptoms of asthma that are poorly controlled by steroids. Serologic evidence for C. pneumoniae infection should be sought in such patients. A trial of appropriate antibiotic therapy may be helpful in those patients with high titers of anti-C. pneumoniae IgG antibodies.

Triamcinolone acetonide aqueous nasal spray for the treatment of patients with perennial allergic rhinitis: a multicenter, randomized, double-blind, placebo-controlled study.

In this multicenter, randomized, double-blind, placebo-controlled study, 178 patients with symptoms of perennial allergic rhinitis (PAR) were treated with either triamcinolone acetonide (TAA) Aqueous nasal spray (220 micrograms once daily) or placebo for 4 weeks. Symptoms of PAR (nasal stuffiness, nasal discharge, sneezing, nasal index, and nasal itching) were evaluated throughout the treatment period through the use of patient diaries. In addition, both patients and physicians completed independent global evaluations of treatment efficacy at the conclusion of the study. TAA Aqueous provided clinically and statistically (P < or = 0.05) greater improvements in nasal stuffiness, sneezing, nasal index, and nasal itching over the 4-week study period than did placebo. Significant improvements in sneezing (P = 0.022) were observed as early as the first day (within 12 to 16 hours based on treatment in the morning and assessment of symptoms at bedtime), and in the nasal index (P = 0.009) by the third day after treatment with TAA Aqueous. Patients' and physicians' global evaluations of overall efficacy were concordant: 65% of patients rated their nasal symptoms greatly or somewhat improved with TAA Aqueous compared with 48% in the placebo group; physicians rated 66% of patients as having greatly or somewhat improved symptoms with the study drug compared with 48% of patients who received placebo. Adverse events were mild and the incidences were comparable for both groups; no significant changes in vital signs or clinical laboratory parameters were observed. This study demonstrated that TAA Aqueous administered once daily was well tolerated and provided relief of PAR symptoms in adults and adolescents.
