Complementary and alternative medicine use in children with asthma.

PURPOSE: To estimate the overall prevalence of complementary and alternative medicine and specific modalities used among children with asthma, identify predictors of use, and perceived positive or negative effects of therapies. RESULTS: Of the 161 children enrolled in the study, 76.4% had ever used complementary and alternative medicine. Humidifiers, air purifiers, and multivitamins were the most common modalities used. Complementary and alternative medicine use in children was associated with family use, younger child age, and disease severity, indicated by recent asthma exacerbation. The majority of participants perceived benefit from their complementary and alternative medicine use, with very few reporting negative side effects. Only 36.7% of participants reported discussing their complementary and alternative medicine use with the asthma clinic healthcare team. CONCLUSIONS: The prevalence of complementary and alternative medicine use in children with asthma is high, with the majority of families perceiving benefit from its use. This study offers clinicians a reference to inform families regarding the subjective helpfulness of various types of complementary and alternative medicine modalities that can facilitate the dialogue between health care professionals and families interested in complementary and alternative medicine use.

Complementary and alternative medicine use in children with cystic fibrosis.

PURPOSE: To estimate the overall prevalence of complementary and alternative medicine use among children with cystic fibrosis, determine specific modalities used, predictors of use and subjective helpfulness or harm from individual modalities. RESULTS: Of 53 children attending the cystic fibrosis clinic in London, Ontario (100% recruitment), 79% had used complementary and alternative medicine. The most commonly used modalities were air purifiers, humidifiers, probiotics, and omega-3 fatty acids. Family complementary and alternative medicine use was the only independent predictor of overall use. The majority of patients perceived benefit from specific modalities for cystic fibrosis symptoms. CONCLUSIONS: Given the high frequency and number of modalities used and lack of patient and disease characteristics predicting use, we recommend that health care providers should routinely ask about complementary and alternative medicine among all pediatric cystic fibrosis patients and assist patients in understanding the potential benefits and risks to make informed decisions about its use.

Canadian Pediatric Asthma Consensus guidelines, 2003 (updated to December 2004): introduction.

BACKGROUND: Although guidelines for the diagnosis and management of asthma have been published over the last 15 years, there has been little focus on issues relating to asthma in childhood. Since the last revision of the 1999 Canadian asthma consensus report, important new studies, particularly in children, have highlighted the need to incorporate this new information into asthma guidelines. OBJECTIVES: To review the literature on asthma published between January 2000 and June 2003 and to evaluate the influence of new evidence on the recommendations made in the Canadian Asthma Consensus Report, 1999 and its 2001 update with a major focus on pediatric issues. METHODS: Diagnosis of asthma in young children, prevention strategies, pharmacotherapy, inhalation devices, immunotherapy and asthma education were selected for review by small expert resource groups. In June 2003, the reviews were discussed at a meeting under the auspices of the Canadian Network For Asthma Care and the Canadian Thoracic Society. Data published up to December 2004 were subsequently reviewed by the individual expert resource groups. RESULTS: This report evaluates early life prevention strategies and focuses on treatment of asthma in children. Emphasis is placed on the importance of an early diagnosis and prevention therapy, the benefits of additional therapy and the essential role of asthma education. CONCLUSION: We generally support previous recommendations and focus on new issues, particularly those relevant to children and their families. This guide for asthma management is based on the best available published data and the opinion of health care professionals including asthma experts and educators.

Fluticasone propionate 100 microg bid using a non-CFC propellant, HFA 134a, in asthmatic children.

BACKGROUND: Secondary to phasing out chlorofluorocarbons (CFCs), the fluticasone propionate (FP) pressurized metered-dose inhaler has been formulated in a nonozone-depleting propellant, hydrofluoralkane (HFA) 134a. OBJECTIVES: To demonstrate equivalent efficacy and safety of FP 200 microg daily propelled by HFA 134a to FP 200 microg daily propelled by CFCs 11 and 12 over a four-week treatment period in pediatric asthmatic patients. METHODS: The study was multinational, randomized, double blind and of parallel group design. Eligible patients aged 16 years and younger were steroid naive or receiving 500 microg/day or less of beclomethasone dipropionate, budesonide or flunisolide, or 250 microg/day or less of inhaled FP. The primary efficacy variable was mean morning peak expiratory flow with equivalence determined if the 90% CIs for the treatment differences between groups were within +/- 15 L/min. RESULTS: Three hundred fifteen patients (mean age 9.3 +/- 2.8 years) were randomly assigned; 158 patients received FP HFA 134a and 157 patients received FP CFC. Over the four-week treatment period, mean morning peak expiratory flow increased from baseline in both groups (14 L/min and 17 L/min, respectively), with a mean treatment difference of -2 L/min. Equivalence was demonstrated between the groups (90% CI -6 to +3 L/min; P=0.589). Both formulations were well tolerated with no serious drug-related events. CONCLUSIONS: FP propelled by HFA 134a has equivalent efficacy and comparable safety to FP propelled by CFC propellants at a microgram equivalent dose in pediatric asthmatic patients.
