  • Circulating adhesion molecules in allergic and non-allergic asthma

    • Circulating forms of adhesion molecules (intercellular-adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and E-selectin ) are related to the turnover of these molecules on the cell surface. In contrast to the other molecules, the levels of E-selectin probably exclusively reflect the activity of endothelial cells. The aim of this study was to compare levels of circulating adhesion molecules in patients with allergic (AA) and non-allergic asthma (NA) and to relate the levels of soluble adhesion molecules to methacholine responsiveness and lung function. The study comprised 19 patients with AA, 15 patients with NA and 17 healthy subjects. Soluble adhesion molecules, spirometry, methacholine responsiveness and peak flow variability was measured. The group of patients with AA had higher levels of sE-selectin than the reference group (P=0.046). Serum levels of sE-selectin correlated significantly with bronchial responsiveness (r=0.76) and peak flow variability (r=0.75) (P<0.01) in the NA but not in the AA group. All adhesion molecules in AA (P<0.05-<0.001), but only sE-selectin in NA (P<0.05), were correlated to airway conductance. sVCAM-1 was reduced by inhaled steroids (P<0.01). Our results indicate that endothelial cells are activated in asthma and that this activity has a bearing on airflow variability and bronchial responsiveness in NA.

  • Dyspnea in relation to symptoms of anxiety and depression : A prospective population study
  • 2006
  • Ingår i: Respiratory Medicine. - : Elsevier BV. - 0954-6111 .- 1532-3064. ; 100:10, s. 1843-1849
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Respiratory symptoms are related to anxiety and depression in several cross-sectional studies but the association has not been explored in longitudinal studies. Study objectives: To prospectively study the change in dyspnea in relation to symptoms of anxiety and depression over a 9-year time period. Methods: The study comprised of 515 adults from a population sample who had participated in the European Commission Respiratory Health Survey (ECRHS) I in 1991-1992 and in the ECRHS II in 1999-2000. The questionnaire included a modified British Medical Research Council Scale for dyspnea grading and the Hospital Anxiety and Depression scale questionnaire. Results: The prevalence of dyspnea was 10.7% in the first and 12.6% in the second survey. Symptoms of depression was an independent determinants for dyspnea in both surveys (OR (95% CI) 3.72 (1.51-9.17) and 3.40 (1.49-7.80), respectively). In subjects that did not have dyspnea at the first survey onset of symptoms of anxiety (OR 3.53 (1.03-12.1)) and depression (OR 12.2 (3.97-37.5)) were significantly related to having dyspnea at the second survey, whereas onset of dyspnea was not significantly associated with developing symptoms of anxiety or depression when each disorder was entered separately. Conclusion: Our data indicates that there is a causal relationship between development of symptoms of anxiety and depression and dyspnea. Psychological status is therefore an important factor to consider both when evaluating the results of epidemiological respiratory studies and in clinical settings when treating patients that have dyspnea.
