Effect of inhaled corticosteroids on bones and growth
Abstract
Inhaled corticosteroids are recognized as the most effective anti-inflammatory therapy in patients with asthma and their early introduction is recommended by national and international guidelines. Concerns have been raised about potential adverse effects of inhaled corticosteroids on bones and growth, as these appear to be more important clinically than effects on the hypothalamic-pituitary-adrenal axis, which are more commonly measured. This review examines the effects of inhaled corticosteroids on biochemical bone markers, bone density and growth in adults and children with asthma, in view of the recent availability of a substantial amount of new clinical trial data. Examination of relevant retrospective and prospective data, involving 11 studies (1,240 patients) on biochemical bone markers and 14 studies (373 patients) on bone density over a wide dose range, have largely indicated no significant or clinically important effect on these measurements in adults or children with asthma. Markers of bone formation and resorption need to be measured concurrently for a reliable assessment of bone turnover to be made. Knemometry, measuring lower leg growth rate, is a sensitive technique for comparing the systemic activity of different...Continue Reading

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
Allergy and Asthma
Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
