Abstract

Knemometry provides a powerful tool for observation of short-term growth patterns. Failure of response to growth-promoting therapies in the short term predicts a poor statural response, but the relationship of the lower leg growth suppression seen with oral and inhaled corticosteroids, and the clinical implications in the longer term, remain unclear. The accumulating evidence suggests that there are measurable biochemical and clinical effects with some inhaled corticosteroids (e.g. beclomethasone dipropionate and budesonide), when given at the upper end of the recommended conventional dose range (18) and for long-term prophylaxis, and certainly at the higher starting doses. It is imperative, therefore, that all children receiving inhaled corticosteroids should have their growth monitored carefully and that the lowest effective dose of corticosteroid should be used.

Use of inhaled corticosteroids and the risk of cataracts.

BACKGROUND: The use of systemic corticosteroids is a risk factor for the development of posterior subcapsular cataracts, but the association between inhaled corticosteroids and cataracts is uncertain. METHODS: We conducted a population-based, cross-sectional study of vision and common eye diseases in an urban area of the Blue Mountains, near Sydney, Australia. We recruited 3654 people 49 to 97 years of age; the participation rate was 82 percent. We collected information by questionnaire on potential risk factors for cataracts, including the current or prior use of inhaled corticosteroids (beclomethasone or budesonide). Photographs of the subjects' lenses were graded, without information on the subjects, to determine the presence and severity of cortical, nuclear, and posterior subcapsular cataracts. RESULTS: Three hundred seventy subjects reported using inhaled corticosteroids, 164 currently and 206 previously. Among these subjects, after adjustment for age and sex, there was a higher prevalence of nuclear cataracts (relative prevalence, 1.5; 95 percent confidence interval, 1.2 to 1.9) and posterior subcapsular cataracts (relative prevalence, 1.9; 95 percent confidence interval, 1.3 to 2.8) than among the subjects with no inhaled-corticosteroid use, but the prevalence of cortical cataracts was not significantly higher (relative prevalence, 1.1; 95 percent confidence interval, 0.9 to 1.3). Higher cumulative lifetime doses of beclomethasone were associated with higher risks of posterior subcapsular cataracts (P for trend <0.001); the highest prevalence (27 percent) was found in subjects whose lifetime dose was over 2000 mg (relative prevalence, 5.5). Adjusting for the use of systemic corticosteroids and other potential confounders had little effect on the magnitude of the associations. The associations with posterior subcapsular cataracts, but not those with nuclear cataracts, were less marked when the analyses were restricted to subjects who had never used systemic corticosteroids. CONCLUSIONS: The use of inhaled corticosteroids is associated with the development of posterior subcapsular and nuclear cataracts.
