| English abstract | BACKGROUND: This investigation evaluated and correlated clinical, laboratorial aspects and psychiatric symptoms in sub clinical hypothyroidism (SH). METHODS: Cross sectional study involving 103 patients with SH and 60 subjects without thyroid disease. Clinical and psychiatric evaluation was respectively based on the Zulewski score and Hamilton A, Hamilton D and Beck questionnaires. Serum thyreotropin (TSH), (thyroxine) FT4 and (antithyroperoxidase) ATPO were measured in all participants. Analysis of continuums data was assessed by the Student t- test, for normally distributed data, and by the Mann- Whitney and Kruskal Wallis tests for non-parametric data. The chi2, Fisher's and Kruskal Wallis tests were used to study qualitative variables. Multivariate analyses were used to study confounding variables. RESULTS: Mean serum TSH level was 7.76 ± 2.9 µUI/mL in SH and 1.66 ± 0.6 µUI/mL in the group without thyroid disease (p=0.001). Mean serum T4L was slightly lower among patients with HS, and showed a negative linear correlation with TSH. Higher frequencies of abnormal clinical score (48.3 vs. 67.0%; p=0.02), depression self reported symptoms (20.5 vs. 44.2%; p=0.011) and anxiety symptoms (86.0 vs. 63.4%; p=0.004) occurred more frequently in SH. Frequency of psychiatric symptoms had a positive correlation with the clinical score and serum TSH. There was no association between the clinical and psychiatric findings and the etiology of SH, presence of ATPO, age or menopause. CONCLUSIONS: The study showed that SH was associated with clinical findings and with psychiatric symptoms. Clinical trials are required to evaluate possible improvement with levotiroxine |

MÉTODOS: Estudo transversal comparando achados de 103 pacientes com HS aos de 60 indivíduos eutireoidianos. A avaliação clínica e a psiquiátrica foram baseadas, respectivamente, na escala de Zulewski e nos questionários de Hamilton A, Hamilton D e Beck. Todos foram submetidos a dosagens de tireotropina (TSH), T4 livre e antitireoperoxidase (ATPO). Variáveis contínuas foram analisadas por meio do teste t de Student, quando de distribuição normal, e dos testes de Mann-Whitney e Kruskal Wallis, quando "não normais". Variáveis categóricas por meio dos testes Qui-quadrado, exato de Fisher e Kruskal Wallis. Análise multivariada foi utilizada para estudo de variáveis de confundimento. RESULTADOS: O nível médio de TSH, no HS, foi 7,76 ± 2,9 µUI/mL e 1,66 ± 0,6 µUI/mL nos eutireoideanos (p=0,001). O nível de T4L foi menor no HS, apresentando correlação linear negativa com TSH. Ocorreu maior freqüência de escore clínico anormal (48,3 vs 67%; p=0,020), de sintomas de depressão, pela escala de Beck no HS (20,5 vs 44,2%; p=0,011) e de sintomas de ansiedade (86 vs 63,4%; p=0,004) no HS. A presença de sintomas de depressão e ansiedade associou-se de forma positiva com pontuação no escore clínico e níveis de TSH. Não houve associação entre achados clínicos ou psiquiátricos e etiologia do HS, presença de ATPO, idade ou menopausa. CONCLUSÃO: O estudo aponta para associação entre |
