Antidepressant Treatment at an Inner City Asthma Clinic
Asthma is common with an increasing prevalence and mortality especially in low-income and minority populations. The course of asthma appears to be influenced by mood and emotions. It has been reported that there is a high prevalence of depression or depressive symptoms in both children and adults with asthma. Despite data on the frequency of depression in asthma and its adverse consequences, it is generally not recognized or treated. Brown et al. conducted a randomized, double-blind, placebo-controlled trial of citalopram in 90 outpatients with asthma and MDD. Citalopram therapy was associated with lower depression scores, numerically greater rates of remission of depressive symptoms, and less oral corticosteroid use than placebo. The investigators proposed study is different. The investigators observed a modest difference between antidepressant and placebo in the prior trial. However, in a subgroup with more severe asthma (based on frequent corticosteroid use) and more severe depression (based on higher depressive symptoms scores) the investigators saw a much larger effect size. Standard of care for severe asthma is aggressive asthma treatment. The investigators study does not require any changes in the patient's asthma treatment. No guidelines are currently available on the treatment of depression in asthma patients. Standard care for depression would be antidepressants.

Conditions
- Depression
- Asthma
Interventions
- High severity group: Escitalopram
- High severity group: Placebo
- Low severity group: Escitalopram
- Low severity group: Placebo
Primary outcomes
- Asthma Control Questionnaire (ACQ) — 12 weeks
The ACQ has 7 questions (the top scoring 5 symptoms, FEV1% pred. and daily rescue bronchodilator use). Patients are asked to recall how their asthma has been during the previous week and to respond to the symptom and bronchodilator use questions on a 7-point scale (0=no impairment, 6= maximum impairment). Clinic staff score the FEV1% predicted on a 7-point scale. The questions are equally weighted and the ACQ score is the mean of the 7 questions and therefore between 0 (totally controlled) and 6 (severely uncontrolled).
