Clinical and laboratorial factors and their relation to asthma severity

Patients and methods We have studied 142 patients with asthma, diagnosed by clinical spirometric findings, attended at the Clinical Immunology outpatient service of an University Hospital. They were divided into two groups according to their asthma severity: group 1 (n=72), mild intermittent or mild persistent asthma, and group 2 (n=70) with moderate or severe asthma. They were submitted to medical history, physical examination and laboratorial routine tests, x-rays, spirometry and aeroallergens skin prick tests, and their findings were compared between both groups.
