  • Description: <jats:sec><jats:title>OBJECTIVE</jats:title><jats:p>The aim of the present study was to evaluate serum soluble interleukin‐1 receptor antagonist (sIL‐1RA) concentration and its relationship with the degree of cigarette smoking in patients with Graves' ophthalmopathy (GO).</jats:p></jats:sec><jats:sec><jats:title>DESIGN AND SUBJECTS</jats:title><jats:p>Twenty‐two consecutive GO patients (20 women, two men; age range 25–68 years, mean 48 years; 12 smokers, 10 non‐smokers) submitted to IV glucocorticoid pulses over a 3‐month period.</jats:p></jats:sec><jats:sec><jats:title>MEASUREMENTS</jats:title><jats:p>sIL‐1RA levels were measured by an immunoenzymatic assay (sensitivity, 4 ng/l; normal range, 50–290 ng/l) before glucocorticoid treatment, after two months of therapy, and 3 months after drug withdrawal.</jats:p></jats:sec><jats:sec><jats:title>RESULTS</jats:title><jats:p>Thirteen patients responded to treatment (59%; five smokers and eight non‐smokers), nine were non‐responders (41%; seven smokers and two non‐smokers). Baseline median sIL‐1RA concentration did not differ in smokers and non‐smokers (222 and 173 ng/l, respectively; <jats:italic>P</jats:italic> = 0.69). Likewise, no significant differences were found between the two groups during treatment (537 and 389 ng/l, respectively; <jats:italic>P</jats:italic> = 0.28); sIL‐1RA concentration after treatment was higher in smokers (258 <jats:italic>vs</jats:italic>. 94 ng/l; <jats:italic>P</jats:italic> = 0.02). There was no correlation between basal sIL‐1RA levels and the degree of cigarette smoking. Likewise, there was no difference in sIL‐1RA levels in responders and non‐responders, either at baseline (186 <jats:italic>vs</jats:italic>. 216 ng/l; <jats:italic>P</jats:italic> = 0.83), during or after treatment.</jats:p></jats:sec><jats:sec><jats:title>CONCLUSION</jats:title><jats:p>Our study suggests that circulating soluble interleukin‐1 receptor antagonist levels, both at baseline and during glucocorticoid treatment, are neither influenced by cigarette smoking nor predictive of subsequent response to glucocorticoid treatment.</jats:p></jats:sec>
