OBJECTIVETo evaluate the results of treatment of infants with congenital hypothyroidism (CH) with a low initial dosage of levothyroxine.
METHODS138 newborns with primary CH detected by neonatal screening were divided into 3 groups according to levels of serum TSH, TT(3) and TT(4): sub-clinical CH (TSH >50 mU/L), mild CH (TT(4) <54 nmol/L), severe CH (TT(4)<54 nmol/L and TT(3)<1.2 nmol/L). The initial dose of levothyroxine was (3.5 +/-1.0) microg/(kg.d) for sub-clinical CH group, (4.3 +/-0.7)microg/(kg.d) for mild CH group and (4.7 +/- 0.6)microg/(kg.d) for severe CH group. Follow-up evaluation was carried out at 1, 2 and 3 months of age by measuring serum levels of TT(3), TT(4) and TSH. The time, when clinical signs and symptoms were eliminated and serum levels of TT(3), TT(4) and TSH normalized, was recorded. Development Quotient (DQ) testing was performed when CH cases were about 2 years old.
RESULTSThe mean initial dose of levothyroxine in 138 cases was (4.3 +/-0.9)microg/(kg.d). In one month the serum TT(3) and TT(4) levels returned to normal, while for TSH levels 67.4 % cases reached normal range in 2 months and 84.1 % in 3 months. Two months after therapy, the levels of TT(3) and TT(4) reached to the upper half of normal range and there were no signs or symptoms of hypothyroidism. The time for all cases in 3 groups to reach the normal clinical and biochemical indicators was similar (P=0.925). The dosage for cases with low circulating thyroxine before treatment was higher than that of the other groups (P<0.01). The average DQ score of 18 cases after treatment was 116.7 +/- 17.0.
CONCLUSIONhe levothyroxine dosage of (4.3 +/- 0.9)microg/(kg.d) is appropriate for the initial treatment of the majority of infants with CH. However it is better to individualize the dosage for each case.

Hypothyroidism has various cardiovascular manifestation and exhibits electrocardiographic change. The QT dispersion on surface ECG reflects regional variations in myocardial repolarization. The effect of L-thyroxine treatment on ECG parameters, such as QT dispersion, in patients with primary hypothyroidism were investigated. This study involved 18 patients (3 men, 15 women, ages: 48+/-18 yr) with primary hypothyroidism. All patients were checked with a standard 12-lead ECG before and after L-thyroxine treatment. Various ECG parameters were then measured twice. The mean L-thyroxine treatment duration was 22+/-2.7 months. The mean thyroid-stimulating hormone levels of patients before and after therapy were 40.2+/-29.8 microU/mL, 3.6+/-4.6 microU/mL (p<0.001) and free-T4 levels were 0.44+/-0.38 ng/dL, 1.51+/-0.39 ng/dL (p<0.001). After L-thyroxine treatment, QT interval (395+/-42 vs. 380+/-24 msec, p<0.05), QTc interval (434+/-32 vs. 417+/-23 msec, p<0.05), QT dispersion (45+/-23 vs. 30+/-13 msec, p=0.008), QTc dispersion (49+/-23 vs. 32+/-14 msec, p=0.005) significantly decreased. There were no significant changes in the PR and RR intervals, as well as the QRS duration. Our findings suggest that the thyroid hormone affects ventricular inhomogenicity, and that L-thyroxine replacement therapy may reduce malignant ventricular arrhythmia and sudden cardiac death in primary hypothyroidism.

Intra-abdominal infection complicated with hypothyroidism is very common. It mostly featured decreased T3, with or without decreased T4, and without elevated thyroid stimulating hormone(TSH). This particular type of hypothyroidism was called "low T3 syndrome" or "thyroid illness syndrome", and is called "non-thyroid illness syndrome" increasingly in recent years. Its pathogenesis has not been fully understood, and probably is associated with abnormality of hypothalamic-pituitary-thyroid axis, disorder of peripheral thyroid hormone metabolism, change in thyroid hormone binding protein, regulation of triiodothyronine receptors, effect of cytokines, and lack of trace element selenium. Intra-abdominal infection complicated with hypothyroidism should be differentiated from primary hypothyroidism, which may be one cause of mental depression, insufficient anabolism, and poor tissue healing. Therefore, the changes of T3 and T4 levels should be actively monitored in patients with severe or prolonged intra-abdominal infection. Whether treatment is needed for intra-abdominal infection complicated with hypothyroidism remains controversial. T3 replacement therapy may improve prognosis. When low T3 syndrome presents as a disease-mediated hypothyroidism, we recommend the use of levothyroxine(L-T4) or liothyronine (L-T3) treatment to improve the prognosis of critical patients. Enteral nutrition can improve hypothyroidism and has good efficacy for enterocutaneous fistula patients with intra-abdominal infection.

6.Treatment of Graves Hyperthyroidism by Jiakangling Capsule Combined with Reduction of 131I: an Efficacy Observation.
Chinese Journal of Integrated Traditional and Western Medicine 2016;36(1):59-62
OBJECTIVETo observe the clinical efficacy of Jiakangling Capsule (JC) combined with reduction of 1311 in treatment of Graves hyperthyroidism.
METHODSTotally 387 Graves hyperthyroidism patients were randomly assigned to the treatment group (200 cases) and the control group (187 cases). Patients in the treatment group took JC combined with reduction of 131I. The 131I dosage per gram of thyroid tissue was 50-80 microCi. They additionally took JC one week after taking 1311 for one consecutive month. Patients in the control group took 131 routinely as one disposable treatment. The 131I dosage per gram of thyroid tissue was 70-120 microCi, without using JC or other anti-thyroid drugs. All patients were reexamined after 24-month treatment. Whether hyperthyroidism was cured, incurred, or permanent was observed. Efficacies of thyroglobulin antibody (TGAb) and thyroid microsome antibody (TMAb) were compared between the two groups.
RESULTSCompared with the control group, the incurred ratio increased in the treatment group [3.2% (6/187) vs. 16.0% (32/200), P < 0.01], the incurred ratio of strong positive TGAb and TMAb patients increased [3.5% (2/57) vs. 27.1% (16/59), P < 0.01], the permanent hypothyroidism ratio decreased [21.1% (12/57) vs. 3.4% (2/59), P < 0.05 ].
CONCLUSIONJC combined with reduction of 1311 was superior in treating Graves hyperthyroidism induced permanent hypothyroidism than routine 1311 treatment, especially for strong positive TGAb and TMAb patients.

Synthetic thyroxine has replaced animal thyroid gland extract as the preferred drug in chronic thyroid hormone replacement. Synthetic thyroxine monotherapy is used to treat overt primary and secondary hypothyroidism, and some cases of subclinical hypothyroidism. In addition, thyroid-stimulating hormone suppressive therapy with thyroxine is a component of the chronic treatment for differentiated thyroid carcinoma. Liothyronine, however, is conventionally for short-term usage, including thyroid hormone withdrawal preparation for radioactive iodine scanning and treatment of differentiated thyroid carcinoma and some cases of myxoedema coma. On very rare occasions where patients are apparently intolerant of or unresponsive to thyroxine, liothyronine may be used chronically. However, there is controversy concerning the use of alternative regimens of thyroid hormone, such as the use of thyroxine-liothyronine combination and thyroid extracts. Thyroid hormone has also been misused to promote weight loss and treat 'symptomatic' biochemically euthyroid patients. There is insufficient evidence to support the use of thyroid hormone to improve treatment response in depression and severe non-thyroidal illnesses.

8.Development of hypothyroidism therapy with thyroid hormone.
Journal of Biomedical Engineering 2005;22(2):396-399
The management of patients with primary hypothyroidism is straightforward. Recent studies suggest, however, that standard thyroid replacement therapy with thyroxine may not be completely effective in relieving the symptoms of hypothyroidism, and that there may be a role for combined use of thyroxine and triiodothyronine (T3) in the replacement therapy. Furthermore, animal studies suggest that the direct contribution by the thyroid to circulating T3 concentrations may be important, and that thyroxine alone may not be adequate treatment for hypothyroidism. In studies on thyroidectomized rats, it was found that the achievement of normal tissue concentrations of T3 required either the thyroxine at high doses which resulted in the suppression of TSH secretion, or the combined thyroxine/T3 treatment, which was able to normalize the serum thyroxine, T3 and the TSH concentrations, and the levels of thyroxine and T3 in most peripheral tissues. If the same is true of humans, there might be a more physiological replacement regimen for hypothyroid patients other than the replacement regiment of using thyroxine alone.

OBJECTIVETo explore the clinical features of respiratory failure secondary to hypothyroidism.
METHODWe retrospectively analyzed the clinical data of 4 patients with respiratory failure secondary to hypothyroidism.
RESULTSRespiratory failure secondary to hypothyroidism usually happened in the aged patients, presenting as myxedema, disturbance of consciousness, anemia, and hyponatrium. Respiratory symptoms were rare. Type II respiratory failure might occur as disease progressed. The clinical presentation of hypothyroidism was atypical and easily neglected. The hypoxia and hypercapnia ameliorated after thyroid hormone therapy.
CONCLUSIONHypothyroidism is a rare reason of respiratory failure. The prognosis is good after hormone therapy and mechanical ventilation.

PURPOSE: In medulloblastoma, craniospinal radiation therapy combined with chemotherapy improves the prognosis of tumors but results in significant endocrine morbidities. We studied the endocrine morbidity, especially growth pattern changes. METHODS: The medical records of 37 patients with medulloblastoma were reviewed retrospectively for evaluation of endocrine function and growth. We performed the growth hormone stimulation test in 16 patients whose growth velocity was lower than 4 cm/yr. RESULTS: The height loss was progressive in most patients. The height standard deviation score (SDS) decreased from -0.1+/-1.3 initially to -0.6+/-1.0 after 1 year(P<0.01). Growth hormone deficiency(GHD) developed in 14 patients. During the 2 years of growth hormone(GH) treatment, the improvements of height gain or progressions of height loss were not observed. Twelve patients(32.4 percent) revealed primary hypothyroidism. One of six patients diagnosed with compensated hypothyroidism progressed to primary hypothyroidism. Primary and hypergonadotropic hypogonadism were observed in two and one patients respectively. There was no proven case of central adrenal insufficiency. CONCLUSION: Growth impairment developed frequently, irrespective of the presence of GHD in childhood survivors of medulloblastoma. GH treatment may prevent further loss of height. The impairment of the hypothalamic-pituitary-gonadal and hypothalamic-pituitary-thyroidal axis is less common, while central adrenal insufficiency was not observed.
