The value of serum thyroid hormone levels in the treatment of patients with refractory depression / 中国生化药物杂志

ABSTRACT

Objective To investigate the value of serum thyroid hormone (Thyroid hormone, TH) levels on prognosis in patients with treatment-resistant depression ( Refractory depression, RD) .Methods 108 cases of RD patients collected in Hangzhou First People's hospital from March 2014 to February 2016 were divided into observation group and control group according to the method of random numbers, and each had 54 patients.Patients in the observation group were given antidepressant treatment program and the control group a placebo.Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA) score changes, and TSH, T3, T4, FT3, FT4 levels of two groups pre-and post-treatment were compared.Results After treatment, the HAMD and HAMA scores in observation group were (14.4 ±2.5) and (15.2 ±2.7) significantly lower than that in control group, which were (25.6 ±5.2) and (25.9 ±4.8),separately, the differences were significant(P<0.05);the TSH, T3, T4, FT3, FT4 levels in observation group post-treatment were (4.54 ±0.68) mIU/L, (1.21 ±0.56) nmol /L, (55.4 ±6.1) nmol/L, (3.16 ±0.42) pmol/L and (8.53 ±0.62) pmol/L, TSH decreased significantly, and T3, T4, FT3 , FT4 were significantly increased than pre-treatment(P<0.05); the indexes in control group were (5.16 ±0.62) mIU /L, (0.91 ±0.42) nmol/L, (51.9 ±3.2) nmol /L, (2.82 ±0.40) pmol/L and (7.76 ±0.64) pmol/L (P<0.05), the differences with observation group were significant ( P <0.05 ) .Conclusion The severity of the symptoms of patients is closely related with TH RD level, antidepressant therapy can improve TH, thereby improving the patient's symptoms, so it is important to pay attention to TH levels in the treatment process of RD.
