BACKGROUND: CXCL10 plays an important role in the initial phases of Graves' disease (GD) and autoimmune thyroiditis (AT); however, until now, CXCL10 serum levels (sCXCL10) in patients with GD have never been evaluated in relation to thyroid function and treatment. OBJECTIVE: To evaluate sCXCL10 in GD. DESIGN: Cross-sectional. PATIENTS: One hundred and three GD, 164 AT, 20 nontoxic multinodular goitre (NTMNG), 16 toxic nodular goitre (TNG) patients and 70 healthy controls (age- and sex-matched). MEASUREMENTS: We measured sCXCL10 in patients and controls, to relate this parameter to the clinical phenotype. RESULTS: Mean sCXCL10 in GD and AT patients were comparable (122+/-81 and 133+/-102 pg/ml) and significantly higher (P<0.01) than in controls or NTMNG patients (73+/- 32 and 76+/- 25 pg/ml, respectively). Hyperthyroid GD had significantly higher sCXCL10 than euthyroid or hypothyroid GD (145+/- 92, 107+/- 56 and 105+/- 46 pg/ml, respectively; P=0.01). GD patients with untreated hyperthyroidism had higher sCXCL10 than hyperthyroid or euthyroid GD patients under methimazole (MMI) treatment (166+/-125, 124+/- 41 and 94+/- 35 pg/ml, respectively; P=0.006). Comparable sCXCL10 levels were observed in newly diagnosed untreated hyperthyroid GD patients with respect to untreated patients with relapse of hyperthyroidism after a previous MMI course (176+/-125, 155+/- 97 pg/ml, respectively). GD had similar sCXCL10 to AT and higher than TNG patients or controls (all age- and sex-matched) (144+/- 81, 149+/- 114, 101+/- 27 and 86+/- 44 pg/ml, respectively; P=0.02). CONCLUSIONS: sCXCL10 is associated with the active phase of GD in both newly diagnosed and relapsing hyperthyroid patients. The reduction in sCXCL10 in treated patients with GD may be related to the immunomodulatory effects of MMI.
