Abstract:
INTRODUCTION:Recent studies show an association between autoimmune thyroiditis and systemic sclerosis (SSc) and suggest that this condition may interfere with the ES phenotype. However these studies evaluate the autoimmune thyroiditis as a whole and none of them specifically addresses Hashimoto's thyroiditis (HT) in SSc. OBJECTIVE:To investigate the presence of HT in SSc patients and its possible association with disease manifestations. METHODS:Clinical manifestations of hypothyroidism, TSH and anti-thyroid auto antibodies (anti-TPO. anti TBG and TRAb) were studied in 56 patients with SSc. SSc patients with HT were compared with SSc patients without thyroiditis. RESULTS:HT was observed in 19.64% of patients with SSc. No association was observed between HT and the different forms of disease or profile of autoantibodies. Likewise, there was no difference between the mean modified Rodnan score and presence of Raynaud's phenomenon, scars, digital necrosis, myositis, arthritis, sicca symptoms, esophageal dysmotility and scleroderma renal crisis when the groups were compared. On the other hand, patients with HT had higher frequency of pulmonary hypertension in relation to patients without HT (66.6% vs 22.5%, p=0.016). CONCLUSIONS:In the studied sample patients with ES and HT had higher prevalence of pulmonary hypertension. Long-term follow-up studies with a larger number of TH and SSc patients are needed to confirm these data.
