ABSTRACT

Introdução: Estudos recentes mostram associação entre tireoidites autoimunes e esclerose sistêmica (ES), e sugerem que essa condição pode interferir no fenótipo da ES. Entretanto, esses estudos avaliam as tireoidites autoimunes como um todo e nenhum deles aborda especificamente a tireoidite de Hashimoto (TH) na ES. Objetivo: Investigar a presença de TH em pacientes com ES e sua possível associação com as manifestações da doença. Casuística e métodos: Manifestações clínicas de hipotireoidismo, TSH, T4 livre e anticorpos antitireoidanos (anti-TPO, anti TBG e TRAb) foram pesquisados em 56 pacientes com ES. Pacientes com ES e TH foram comparados com pacientes com ES sem tireoidite. Resultados: TH foi observada em 19,64% dos pacientes com ES. Não foi encontrada associação entre a TH e as diferentes formas de doença ou com o perfil de autoanticorpos. Da mesma forma, não houve diferença entre a média do escore de Rodnan modificado e entre a presença de fenômeno de Raynaud, cicatrizes estelares, necrose digital, miosite, artrite, sintomas sicca, dismotilidade esofágica ou crise renal esclerodérmica quando os grupos foram comparados. Por outro lado, pacientes com TH apresentaram maior frequência de hipertensão pulmonar quando comparados a pacientes sem TH (66,6% vs 22,5%; p = 0,016). Conclusões: Na amostra de ES estudada, a TH está associada a uma maior prevalência de hipertensão pulmonar. Estudos de seguimento a longo prazo, englobando um número maior de pacientes com ES e TH, são necessários para confirmar esses dados. .


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. .
