Equivalence of a single saline nebulised dose of formoterol powder vs three doses of nebulised Albuterol every twenty minutes in acute asthma in children: a suitable cost effective approach for developing nations.

BACKGROUND: An increase in asthma prevalence is reported from developed as well as developing nations, with rising costs from acute asthma and great expenditures to health care systems. Venezuela's Ministry of Health ambulatory facilities care for 80 % or more of a mostly urban and impoverished population of 26 million inhabitants, registering close to a million acute asthma visits per year; a nebulised fixed fenoterol-ipratropium bromide combination (Bero-dual, Boehringer-Ingelheim) in repeated dosing is the standard treatment. OBJECTIVES: to simplify acute asthma care and management in a cost effective manner employing Formoterol Fumarate powder, a long acting beta agonist with immediate bronchodilator effects. METHODOLOGY: Fifty acute asthmatic children (5-12 years old) were randomly assigned (25 patients in each group) to receive either a nebulised single dose (US $1.35) of two 12 microg Formoterol Fumarate capsules (Foradil 12 microg/cap, Novartis Pharma AG, Basel, Switzerland) diluted in 2.5 ml of sterile saline solution; or 3 doses of Albuterol (US $ 6.73) every twenty minutes for one hour (Glaxo Smith Kline Albuterol ampoules, 2.5 mg/2.5 ml, at a dose of 0.15 mg/kg/dose, maximum dose 2.5 mg). Symptoms score, oxygen saturation and lung function testing were recorded before and one hour after commencing treatments. RESULTS: Both groups improved significantly on all parameters, except for FEV(1) in the Albuterol group. CONCLUSIONS: Single dose nebulised Formoterol Fumarate (dry powder) in sterile saline solution, as depicted in this trial, is equivalent to three doses of Albuterol every twenty minutes for one hour in acute asthma in children, simplifying acute care management and at one fifth of medication costs. A pursuit of simpler and more cost effective approaches is found wanting in developing nations with depressed economies and unique cultural and socio-medical contexts; also, in countries where pharmaco-economics orients quality of health policies, novel approaches like this are worth exploring.

Children's asthma and the third world: an approach.

BACKGROUND: More than a million visits/year characterize acute asthma morbidity at Venezuela's (24 million inhabitants) Ministry of Health ambulatory services, caring for 80% or more of the population; acute morbidity from asthma is second to "viral syndrome" but ahead of diarrhea and other diseases. These acute episodes are the only contact of a poor asthmatic child with this health care system and portray the prevailing approach focused around acute care: to be reversed, a simple cost/effective program ought to be implemented during these acute asthma visits. Since convenience of administration is a key factor in compliance, a pilot study to explore the efficacy of budesonide CFC 400 microg administered on a once-a-day basis for adherence was carried out within a naturalistic real-world design. METHODS: Thirty persistent asthmatic patients attending the Allergology Unit of the Hospital Pediátrico San Juan de Dios in Caracas were enrolled, and their asthma signs/symptoms quantified and registered on diary cards (0-3 scale) as well as peak flow measurements in am/pm for a period of 2 weeks prior to budesonide administration (control data) and until completion of study. Only 12 (mean age: 9 years) of the initial patients were able to properly keep a diary and scheduled visits for a period of 15 weeks. RESULTS: Data allowed comparison between pre- and post-treatment symptoms/signs scores and PF values. After 3 weeks treatment with budesonide, statistically significant improvements were shown for all parameters, except for PF, whose minor improvements did not reach statistical significance. CONCLUSIONS: Budesonide CFC 400 microg administered once a day seems effective in control of asthma signs/symptoms within study design. Confirmation of the above findings in larger groups of patients, treated similarly and for longer periods of time, seems justified. A simple cost-effective intervention, analogous conceptually to the proven successful oral rehydration therapies for diarrhea in public health, should be considered in third world countries with high urban asthma prevalence.
