Global Initiative for Asthma (GINA) guideline: achieving optimal asthma control in children aged 6-11 years
Abstract
The Global Initiative for Asthma (GINA) 2021 guidelines for asthma have been set forth with some alterations in Step 3, for children from 6-11-year-old age group. The low dose LABA-ICS, very low dose formoterol-ICS, medium dose ICS and ICS-LTRA combination were recommended in the guideline. We organized this study to draw an effective comparison between these three combinations of controller therapies in pediatric population. A retrospective study was conducted at the Aga Khan University Hospital, Karachi, Pakistan which enrolled 114 children aged 6-11 years old, from July 2021 to December 2022. These children were admitted with asthma exacerbations and were discharged on controller medications as per GINA guidelines on step 3 for control of asthma for 3 months. They were then followed for re-admission within 30 days of discharge, number of ER visits with asthma exacerbations for 1 year, number of admissions with asthma including HDU and PICU admissions, length of stay per admission for all admissions in subsequent one year. The pulmonary function test was done at 1 week follow-up in clinic after discharge and at 3 months visit post discharge. A total of 114 pediatric patients from age 6-11-year-old, were enrolled in the study period out of which 36 (31.57%), 33(28.9%) and 34 (29.82%) patients were categorized into ICS-LABA, ICS and ICS-LTRA groups respectively. ER visits were significantly low in ICS-LABA group followed by ICS-LRTA group and then ICS group (1.75±0.96 vs 2.93±1.412 vs 3.11±1.21, p<0.001). Similar statistically significant results were observed on average number of admissions per year (1.52±1.02 vs 1.96±0.84 vs 2.06±1.07, p=0.047) and number of patients needing PICU (13.88% vs 26.47% vs 39.39%, p=0.034) in these groups respectively. ICS- LABA group patients had the best values of FEV1 and FEV1/FVC ratio after pulmonary function tests at 3 months follow-up followed by ICS-LTRA and ICS group. Amongst the three options regimens for children managed at step 3 on GINA 2021 guidelines, ICS-LABA therapy helps attain optimal patient outcomes and lung functions in children with asthma followed by ICS-LTRA and ICS group respectively.
