ABSTRACTS / 21 ST NORDIC CONGRESS OF ALLERGOLOGY Results: Comparing pre- and post-therapy levels, IL-10 levels increased 15-fold and 5-fold al'ter the first and second treatment period, respectively. TNFa levels increased 7-fold and 20-fold after the first and second treatment period, respectively. CD14 increased 9-fold in monocytes. Conclusion: IL-10 and TNFa levels in blood seem to increase, as does the expression of receptors associated with inflammation (CD14) during intravenous IgG treatment. A transient and minor clinical improvement was observed. P 2 - Fluticasone propionate attenuated the late asthmatic reaction more effectively than montelukast Bruce C, Palmqvist M, Sjöstrand M, Aronsson B, Arvidsson P, Lotvall J Background: Asthma is an inflammatory disease. The aim of this study was to determine the anti-inflammatory effects of montelu- kast (M) compared to fluticasone propionate (FP) and placebo (P). Methods: In a randomised, double blind study, mild allergic asthmatics with an early and late (EAR and LAR) asthmatic reaction after bronchial allergen challenge participated. Treatments with FP 250pg x 2, M 10 mg x 1 or P was given for 8 days. On day 7 a bronchial allergen challenge was done. After 7 and 24 hours a sputum induction was performed. A methacholine challenge was done after 24 hours. Results: 8 patients (6 allergic to cat, 1 birch, 1 horse) participated. Their mean baseline FEV, was 92% pred (67-104%). At screening thr max FEV|-fall during the EAR (0-lh) was 28% (20-42%) and during the LAR (3-7h) 28% (16-56%). After M the max FEVrfall during EAR was 12%±6.4 (SD), compared to after FP 18%±8.8 (SD), p=0.05. The max fall in FEV! during the LAR was signifi- cantly attenuated after FP, 3%±4.9 (SD), compared to after M, 14%±13.6 (SD), p=0.04, and after P, 19%±16.7 (SD), p=0.01. There was no statistically significant difference on the LAR between M and P. After FP the percentage eosinophils in sputum (sputum eos%) was significantly reduced at 7 h, 11%±17.1 (SD) compared to after P, 26%±27.4 (SD), p=0.02. Also after M sputum eos% was significantly reduced, 14%±15.5 (SD), compared to P, p=0.03. In opposite to eosinophils in sputum % there was no difference in blood eosinophils for the different treatments. Metacholine respon- siveness at 24 h was in relation to P reduced by 2.2 dose steps after FP and by 0.2 dose steps after M (p=0.01). Conclusion: In theses allergic asthmatics, fluticasone propionate inhibited the LAR, reduced the associated sputum eosinophilia and the metacholine responsiveness more effectively than montelukast. The superior anti-inflammatory effects by fluticasone propionate are confirmed. P 3 - Close association between thyroid autoimmunity/ autoimmune disease and chronic idiopathic urticaria Zauli D, Contestabile S, Grassi A, Zucchmi S, D'Ecclesia AR Abstract: Almost 20 years ago now a fairly high prevalence of thyroid autoantibodies was described in patients with chronic urticaria of unknown origin (idiopathic). We have subsequently confirmed a stronger association in a series of 122 patients. In the present study, we have updated our data in a larger series of such patients: 246 cases, comprising 148 women and 88 men. Anti-thyroid peroxidase antibody (anti-TPO) alone was found in 6%, anti-thyroglobulin (anti-TG) alone in 3.6% and both antibodies in 13%. Any autoantibody was therefore detected in 23.7% cases, which is significantly higher than the expected preva- lence in the general population: 1-10%. As expected prevalence rates were higher in wornen than in men: 29% vs 14.7%. A condition of frank or subclinical dysthyroidism was present in about 40% antibody positive cases. Whereas both hypo (32%) and hyperthyroidism (9%) were detected in female patients, in men only hypothyroidism (38%) was documented. A low rate of response of urticaria symptoms to treatment of the thyroid dysfunction was observed in our cases. In conclusion, although many recently published guidelines for the management of chronic idiopathic urticaria do not include evaluation of thyroid autoimmunity and function and the benefit of treatment seems low, we still highly recommend to test for anti-TPO, anti-TG and serum thyrotropin all idiopathic cases. This also in view of the morbidity associated with both hypo and hyperthyroidism. P 4 - Quality of life and capsaicin sensitivity in patients with airway symptoms induced by chemical agent Ternesten-Hasséus E, Löwhagen O, Millqvist E Asthma and Allergy Research Group, Department of Respiratory Medicine and Allergy, Sahlgrenska University Hospital, Göteborg, Sweden Email: ewa.ternesten@lungall.gu.se Objectives: Earlier studies have shown increased cough sensitivity to inhaled capsaicin in patients developing airway symptoms from chemical agents, but without bronchoconstriction or an IgE- mediated allergy. Our aim was to study cough sensitivity to and reproducibility of a capsaicin inhalation test in such patients, and to illuminate health economical factors and estimate their quality of life. Methods: Eighteen patients with airway symptoms triggered by chemical agents, but with negative asthma/allergy tests, were provoked with a capsaicin inhalation test in three increasing dose steps, every third month. They were interviewed once a month about their work capacity and medication. Quality of life was measured with a general health profile (Nottingham Health Profile [NHP]). Results: The mean number of coughs on the second dose of capsaicin was 49 [32; 66] at the first visit, 54 [35; 72] at the second, 54 [37; 70] at the third, and 43 [27; 59] at the last visit. The corres- ponding values among healthy control subjects were 9 [6; 12]. Eleven per cent of the patients had early disability retirement, 50% were periodically on sick leave and 56% had changed work because of their sensitivity to chemicals. Thirty-three per cent took nasal de- congestants regularly and 50% used medication for the lower airways. The NHP showed an influence on several dimensions of daily life. Condusions: Sensitivity to inhaled capsaicin seems to be stable and to have good reproducibility. Airway symptoms induced by chemical agents have a great influence on patients’ quality of life and on health economical factors. 20 Læknablaðið/Fylgirit 46 2002/88
