He presented at 34 months of age with developmental delay, ataxia, nystagmus, optic atrophy and a mild, persistent metabolic acidosis.
Four clusters were identified (severe persistent, moderate persistent, mild persistent, and fluctuating).
Asthma is classified based on the degree of symptom severity, which can be divided into four categories: mild intermittent, mild persistent, moderate persistent, and severe persistent.
Most patients had moderate or severe COPD, and mild persistent or moderate persistent asthma.
While 31.6% of the mild persistent, 28.6% of the moderate persistent asthma patients were prescribed with oral corticosteroid that was only recommended for severe persistent asthma.
Asthma severity was first classified as intermittent, mild persistent, moderate persistent, or severe persistent using the GINA guidelines[13] that were available at the time of ECRHS-I.
According to the 1992 GINA classification, 40.7% of asthmatics at baseline were classified intermittent, 31.7% as mild persistent, 14% as moderate persistent, and 13.5% as severe persistent.
At baseline, asthma severity according to GINA was distributed as intermittent: 40.7%, 31.7% as mild persistent, 14% as moderate persistent, and 13.5% as severe persistent.
Asthma severity 1 = Intermittent, 2 = Mild persistent, 3 = Moderate persistent, 4 = Severe persistent.
Asthma severity according to GINA criteria was: 2.8% mild intermittent, 18.5% mild persistent, 48% moderate persistent and 30.6% severe persistent.
