Management according to the Global Initiative for Asthma guidelines of patients with near-fatal asthma reduces morbidity and mortality
Abstract
To assess the effect of adequate outpatient care as defined by guidelines of the Global Initiative for Asthma (GINA) on the long-term outcome of near-fatal asthma. Fifty-three patients who had experienced a near-fatal attack of asthma were treated according to the GINA guidelines and followed for a mean of 49 months (intervention group). Clinical and spirometric measurements corresponding to the periods before the attack (obtained retrospectively) and after the attack (obtained prospectively) were compared to measurements from 40 near-fatal asthma patients who had not been managed according to the GINA guidelines and who were followed for a mean of 51 months (historic control group). There were no deaths in the intervention group and 6 deaths (15%) in the control group (P=.005). The mean (SD) number of new near-fatal asthma attacks was significantly lower in the intervention group (0.17 [0.61]) than in the control group (1.6 [1]) (P< .001). Emergency visits following a near-fatal asthma attack decreased from 0.9 (1.8) to 0.3 (0.6) in the intervention group and hospital admissions decreased from 3.4 (5.1) to 0.5 (1.4) (P< .001). Eosinophil count decreased from 390 (411) x l0(9) cells/L to 159 (121) x l0(9) cells/L (P=.01) and fo...Continue Reading

Asthma
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.
