Cough sensitivity in atopic dermatitis.

The aim of study was to investigate the cough sensitivity (C2) to capsaicin (CAPS) in patients with atopic dermatitis without clinical respiratory symptoms. Cough sensitivity (C2) is defined as the lowest CAPS concentration, which evokes two or more coughs. Forty eight dermatological patients (21 M, 27 F; mean age 44 yr) and 24 healthy volunteers (14 M, 10 F; mean age 37 yr) inhaled deep breath (2 l) of CAPS aerosol in doubled concentrations (from 0.02 to 200 micromol/l) (Pari Provokationstest I, PARI WERK; mass median diameter 1.2 microm). Cough sensitivity (C2) expressed as geometric mean (95% CI) of CAPS concentration was 0.13 micromol/l (0.06-0.31) in 26 patients with atopic dermatitis (10 M, 16 F; mean age 41 yr), 5.51 micromol/l (1.33-22.90) in 22 patients with psoriasis (11 M, 11 F; mean age 46 yr) and 4.29 micromol/l (2.54-7.26) in 24 controls. There is significant difference of cough sensitivity (C2) between patients with atopic dermatitis and healthy volunteers (p<0.001) and also between patients with atopic dermatitis and psoriasis (p<0.001). Cough sensitivity (C2) in atopic dermatitis patients without clinical respiratory symptoms is significantly increased. In patients with psoriasis cough sensitivity (C2) is not significantly changed.

Cough sensitivity in localized scleroderma with no clinical symptoms from lower airways.

Cough sensitivity is increased in patients with atopic dermatitis, although they have no clinical symptoms from the lower airways. In the present study we examined the cough sensitivity to capsaicin in patients, who had no clinical respiratory symptoms, with sclerodermia localized to the skin. Cough sensitivity was defined as the lowest capsaicin concentration, which evokes 2 or more coughs. Twelve patients and 12 healthy matched volunteers, as a comparison group, inhaled deep breaths (2 L) of a capsaicin aerosol in doubled concentrations (from 0.02 to 200 micromol/L). Cough sensitivity, expressed as a geometric mean (95% CI) of capsaicin concentration, was 0.15 micromol/L (0.04 to 0.56) in the patients with localized sclerodermia and 4.96 micromol/L (2.50 to 9.85) in controls, which made a significant difference towards higher cough sensitivity in sclerodermia, respiratory symptom-free patients. Thus, disease processes localized outside the respiratory tract may have surreptitious pulmonary manifestation that is brought to light by the capsaicin cough test.
