fluticasone and Bronchiolitis

To investigate the efficacy of fluticasone propionate aerosol (flixotide) versus budesonide suspension in the treatment of recurrent wheezing caused by bronchiolitis.. A total of 214 infants with newly diagnosed bronchiolitis were randomly divided into flixotide treatment (106 infants) and budesonide treatment groups (108 infants), and were given aerosol inhalation of flixotide or budesonide for 3 months after achieving remission of clinical symptoms. Another 136 infants with bronchiolitis who did not receive regular inhalation of corticosteroid after achieving remission of clinical symptoms were enrolled as the control group. The follow-up visits were performed for 1 year, and the effects of the two therapeutic methods on recurrent wheezing were evaluated.. Compared with the control group, both the flixotide and budesonide treatment groups had significantly fewer times of wheezing episodes within 1 year and a significantly lower recurrence rate of wheezing within the first 3 months after regular inhalation of corticosteroid, but no significant differences were observed between the two treatment groups. The amount of corticosteroid inhaled and hospital costs in the budesonide treatment group were significantly higher than in the flixotide treatment group (P<0.01).. Continuous inhalation of flixotide or budesonide after remission of clinical symptoms in children with bronchiolitis can reduce wheezing episodes and the recurrence of wheezing, and flixotide treatment is superior to budesonide treatment in the aspects of hospital costs and the amount of corticosteroid used.

Information on the dose of steroid infants inhale from spacer devices and its potential effect on adrenal suppression is limited.. We sought to determine the total dose of fluticasone propionate (FP) inhaled from a spacer device (Babyhaler) with face mask attachment by infants recovering from acute bronchiolitis and the effect of inhaled FP on the infants' overnight urinary cortisol/creatinine ratios (UCCRs).. Infants studied were recovering from acute bronchiolitis. In study 1, 22 infants inhaled 150 microg of FP through the Babyhaler. The likely inhaled dose was estimated by trapping it on a filter held within the face mask. In study 2, 40 infants had UCCRs measured before and during 3 months of treatment with either FP (150 microg twice daily, n = 20) or placebo (n = 20).. In study 1 the mean +/- SD dose of captured FP was 12.8 +/- 6.9 microg (ie, 2.1 +/- 1.2 microg/kg). In study 2 the pretreatment UCCR medians (interquartile ranges) were as follows: FP, 22.8 (23.0) nmol/mmol; placebo, 24.0 (28.3) nmol/mmol. Within-group UCCR changes (median and interquartile range DeltaUCCR) were significantly different in the FP group (-8.9 and -20.6 nmol/mmol at 6 weeks and -12.6 and -25.9 nmol/mmol at 12 weeks, respectively; P =.0008) but not in the placebo group ( -5.8 and -10.7 nmol/mmol at 6 weeks and +0.3 and -17.9 nmol/mmol at 12 weeks, respectively; P =.45). Intergroup changes were insignificant in the follow-up period (6 weeks, P =.52; 12 weeks, P =.19).. After bronchiolitis, infants are likely to inhale approximately 8 % of the nominal steroid dose from the Babyhaler. UCCRs can be used to monitor the bioavailability of inhaled steroids in young infants.

A 56-year-old woman was referred to our hospital because of dyspnea, wheezing, and a productive cough. Eight years before presentation, bronchial asthma was diagnosed and the patient received inhaled corticosteroids plus antiasthmatic agents (a long-acting inhaled beta2-agonist, leukotriene modifiers, and theophylline). Chest radiography showed small diffuse nodular shadows, and a computed tomographic scan showed thickening of the bronchi and bronchioles, with diffuse centrilobular nodules in both lung fields. A blood test and microscopic examination of the bronchoalveolar fluid revealed marked eosinophilia. Transbronchial lung biopsy and transbronchial biopsy showed eosinophilic bronchitis and bronchiolitis. After treatment with oral prednisolone (40 mg daily) and inhaled corticosteroids, the symptoms, blood eosinophilia, and radiographic findings improved. Recently, several similar cases of eosinophilic bronchiolitis have been reported. Studies of further cases and elucidation of the pathophysiology of eosinophilic bronchiolitis are necessary to establish a concept for this disease and to determine whether it should be classified as a subtype of bronchial asthma or as a distinct entity.
