Body Mass Index and Comorbidities in Adult Severe Asthmatics

الملخص EN

Both severe asthma and obesity are growing health problems.

Severe asthma leads to a poor quality of life.

The relationship among BMI, comorbidities, and severe asthma control in adults is still unclear.

The aim of the study is to better understand the effect of the comorbidities as atopy, type II diabetes, OSAS, gastroesophageal reflux, hypertension, cardiovascular diseases, osteoporosis, infections, and psychological factors with BMI on asthma control in a cohort of adult severe asthmatics.

One hundred and two patients were enrolled in a cross-sectional study assessing asthma control, treatments, pulmonary function, inflammatory markers, and comorbidities.

Patients were divided into 3 classes according to BMI: normal weight, overweight, and obese.

We found that the optimal state of asthma control is lower.

whereas the score of Asthma Control Questionnaire, the number of asthma exacerbations during last year, the oral corticosteroids requirement during the previous year, and the LABA treatments are higher in obese than in overweight and normal weight severe asthmatics.

The number of subjects with type II diabetes and OSAS are higher among obese and overweight patients than in normal weight asthmatics.

In conclusion, BMI represents per se a factor for the deterioration in disease control in severe asthma.
