Objective To dynamically observe the early change of thyroglobulin(Tg) levels after (131)I therapy in differentiated thyroid cancer(DTC) patients. Methods The study enrolled 22 post-total-thyroidectomy DTC patients and they were stratified as low to intermediate recurrence according to the 2009 American Thyroid Association Guidelines. The clinical data including pre-ablation stimulated Tg (ps-Tg),corresponding thyroid stimulating hormone(TSH),anti-thyroglobulin (TgAb) values,and the afterwards parameters were dynamically measured each week in the first month after (131)I therapy. Values collected at the first time were defined as Tg 0 and TSH0,while Tg1 and TSH1 were collected at the first week after (131)I therapy respectively. Then the variation trend curves of Tg were drawn,and factors influencing the variation of Tg were analyzed. Two groups were divided according to Tg levels:G1 (Tg≤0.1 ng/ml,n=9) and G2(Tg>0.1 ng/ml,n=13). Results The rates of negative Tg were 4.5%,18.0%,27.0%,36.0%,and 41.0%,respectively,exactly before (131)I therapy and the 1(st),2(nd),3(rd),and 4(th) week after the therapy. One-way analysis of variance showed that the two groups statistically differed in age (F=3.182,P=0.04) and remnant thyroid (U=4.849,P=0.026). Multivariate logistic regression analysis showed that early negative Tg was related to remnant thyroid tissue (OR:2.132;95%Cl:1.418- 6.532,P=0.009). Conclusions Negative Tg can be achieved in nearly half of DTC patients by the end of first month after (131)I therapy. The negative conversion is closely related with the volume of remnant thyroid tissue.

This study aimed to evaluate the effects of thyroid hormone supplementation on growth rate of children with idiopathic short stature (ISS) and low-normal serum free thyroxine FT4 who were receiving growth hormone therapy. We selected 64 prepubertal children with FT4 levels in the lowest third of the normal range as the lower FT4 group, and these children were divided randomly into two subgroups: L-thyroxine (L-T4)-treated subgroup was treated with L-T4 (0.5-3.0 g/(kg·d)) from the beginning of the study, and the non-L-T4-treated subgroup received placebo. We also selected 39 ISS children with FT4 in the upper two-thirds of the normal range as the higher FT4 group. During the first year, the lower FT4 group featured lower FT3, FT4, thyroid stimulating hormone (TSH), and insulin-like growth factor-I standard deviation score (IGF-I SDS) and significantly lower height velocity (HV) compared with the higher FT4 group. However, in the lower FT4 group, the L-T4-treated subgroup presented higher FT4, FT3, TSH, and IGF-I SDS concentrations and significantly higher HV compared with children in the non-L-T4-treated subgroup. In children with ISS, the negative effect of thyroid hormone deficiency on growth rate should be considered when FT4 level lies in the low-normal range prior to recombinant human growth hormone treatment.

BACKGROUNDLittle information about the current management of patients with thyroid-stimulating hormone (TSH)-secreting pituitary adenomas or about the usefulness of the somatostatin analogue octreotide was contained in the literature. This study aimed to report the efficacy and safety of the long-acting octreotide formulation in patients with TSH-secreting pituitary adenomas after incomplete surgery and octreotide treatment failure.
METHODSFifteen patients with TSH-secreting pituitary adenomas (8 men and 7 women), who previously underwent incomplete surgical resection and/or adjuvant radiotherapy (n = 12) and failure of octreotide treatment (n = 15), followed between 2007 and 2010 in Beijing Tiantan Hospital were included in this study. All patients received 1- to 2-months of the long-acting octreotide formulation treatment after the above combination of treatment. Paired samples t-test was used to analysis the variables.
RESULTSAfter two-month duration of the long-acting octreotide formulation treatment, the mean serum free or unbound thyroxine (FT4) ((16.02 ± 1.72) pmol/L) and free triiodothyronine (FT3) ((2.87 ± 0.43) pmol/L) levels of 15 patients significantly decreased compared with those after octreotide-treatment (FT4, (35.36 ± 7.42) pmol/L, P < 0.001; FT3, (17.85 ± 7.22) pmol/L, P < 0.001). Mean TSH levels stayed in the normal range after the long-acting octreotide formulation treatment ((0.72 ± 0.21) mU/L) and were significantly lower than the pretreatment value ((5.27 ± 1.04) mU/L, P < 0.001), post-surgery value ((3.37 ± 0.31) mU/L, P < 0.001) and post-octreotide-treatment value ((4.52 ± 0.41) mU/L, P < 0.001). In these patients with TSH-secreting pituitary adenomas there was no evidence of tachyphylaxis.
CONCLUSIONThe long-acting octreotide formulation may be a useful and safe therapeutic tool to facilitate the medical treatment of TSH-secreting pituitary adenomas in patients who underwent incomplete surgery or need long-term somatostatin analog therapy.

Primary hypothyroidism and type 2 diabetes are both typically associated with the increased level of triglycerides. To date, there have been only a few case reports of type 2 diabetes patients with both type V hyperlipoproteinemia and eruptive xanthomas, but there have been no reports of hypothyroidism patients associated with eruptive xanthomas. We report here on a case of a 48-yr old female patient who was diagnosed with type 2 diabetes and primary hypothyroidism associated with both type V hyperlipoproteinemia and eruptive xanthomas. We found rouleaux formation of RBCs in peripheral blood smear, elevated TSH, and low free T4 level, and dyslipidemia (total cholesterol 18.1 mM/L, triglyceride 61.64 mM/L, HDL 3.0 mM/L, and LDL 2.54 mM/L). She has taken fenofibrate, levothyroxine, and oral hypoglycemic agent for 4 months. After treatment, both TSH level and lipid concentration returned to normal range, and her yellowish skin nodules have also disappeared.

5.Clinical application of recombinant human thyroid-stimulating hormone in management of differentiated thyroid carcinoma.
Journal of Biomedical Engineering 2012;29(3):588-592
Traditionally, during the follow-up and in order to receive 131 I therapy, patients with differentiated thyroid carcinoma (DTC) have to withdraw from using thyroid hormone. The hypothyroidism induced by hormone withdrawal can negatively affect the quality-of-life (QOL) of DTC patients. Without the hormone withdrawal, recombinant human thyroid-stimulating hormone-aided management of DTC patients can effectively obviate the consequences of hypothyroidism. This review will focus on the clinical application of recombinant human thyroid-stimulating hormone (rhTSH) in the management of DTC patients.

OBJECTIVETo measure the levels of hormones in chronic myelogenous leukemia (CML) patients receiving imatinib mesylate (IM) and evaluate the effects of IM on endocrine system.
METHODS69 patients with CML while taking IM were enrolled and a total of 86 peripheral blood samples were detected. The levels of total triiodothyronine (TT3), total tetraiodothyronine (TT4), thyroid stimulating hormone (TSH), testosterone, progesterone, estradiol (E2), plasma total cortisol (PTC) at 8:00-10:00 am measured. Concentration of hormones in different groups were measured to evaluate the effects of IM on endocrine system and relationships with its administration duration, plasma concentration and clinical symptoms.
RESULTS(1) Of the 7 types of hormones, an elevation of TSH level was found in 14 patients (20.3%), a decrease of TT3 and testosterone in 8 patients (11.6%) and 8 males (18.6%), respectively. (2) A significant decline of TT3 and testosterone was observed in all patients divided by different administration duration. Negative correlation was seen between TT3 level and duration of administration (r=-0.273, P=0.010), which was also found for testosterone (r=-0.302, P=0.025). (3) There was no correlation between serum levels of the seven hormones and concentration of IM.
CONCLUSIONIM affect the levels of thyroid and sex hormones in some patients with clinical manifestations: a decrease of TT3, testosterone and testosterone, an increase of TSH, which have relationship with the duration of administration.

7.Pituitary hyperplasia secondary to primary hypothyroidism in children: report of 8 cases.
Chinese Journal of Contemporary Pediatrics 2010;12(1):17-20
OBJECTIVETo study the changes in hormone levels and the therapy of pituitary hyperplasia secondary to primary hypothyroidism in children.
METHODSThe clinical data of 8 children with pituitary hyperplasia secondary to primary hypothyroidism (5 girls and 3 boys) at ages of 5 to 9 years were studied retrospectively. All of the children had a short stature. They were followed up 1 to 6 years.
RESULTSThe thyroid hormone levels decreased and the serum thyroid stimulating hormone (TSH) and prolactin (PRL) levels increased in the 8 children. After 2 to 6 months thyroxine replacement therapy, the levels of free triiodothyronine (FT3), free thyroxine (FT4) and serum TSH and PRL returned to normal, and the pituitary enlargement regressed to normal in the 8 children. Of them, 6 children's height growth rate increased significantly from 3.1+/-0.5 cm per year to 11.6+/-1.7 cm per year (p<0.01). The other 2 cases had low growth rate and then received additional recombinant human growth hormone (rhGH) therapy. Their height growth rate increased by 11 cm per year. Pituitary hyperplasia did not recur in the 8 children during the follow-up.
CONCLUSIONSThe thyroid function and pituitary examinations are necessary for children with a short stature. Thyroxine substitution therapy appears to be effective for primary hypothyroidism secondary to pituitary hyperplasia. rhGH replacement therapy after regression of the pituitary enlargement can result in a satisfactory height growth in children with low thyroid hormone levels and growth hormone deficiency.

OBJECTIVETo study the best observation time for drug administration and withdrawal in the treatment of children with transient congenital hypothyroidism,seeking an objective basis for the safe drug withdrawal.
METHODSLevothyroxine was prescribed for 1 144 children diagnosed with congenital hypothyroidism (CH) and according to the results levothyroxine was adjusted to a maintenance dosage. Examinations were performed periodically including physical and mental development, thyroid ultrasonography,and blood levels of T3, T4, TSH. For the patients with a small maintenance dosage of levothyroxine (15.0 - 16.6 g/d) and all the examinations normal, levothyroxine was withdrawn at 2 - 3 years, and the children were followed up and reexamined after 1 month, 2 months, and 10 months, respectively. Permanent drug withdrawal was determined for children with all the examinations normal. Once abnormal TSH occurred, levothyroxine was prescribed again, and followed up continuously.
RESULTLevothyroxine was withdrawn from 157 children. During the follow up, for 15 children (9.55%) levothyroxine were prescribed continuously, and for 142 children permanent drug withdrawal (confirmed with transient CH) was determined. Abnormal TSH of various degrees was detected in 48 cases: 25.48 % (40/157),4.46 % (7/157), and 0.64 % (1/157) were detected at 1, 2 and 10 months after drug withdrawal, respectively. In 15 children levothyroxine was prescribed again for the remarkably high TSH, and the other 33 with mildly abnormal TSH finished the treatment since TSH normalized during follow-up.
CONCLUSIONAfter 2 - 3 years of regular treatment, levothyroxine can be withdrawn from children with normal T3, T4, TSH, physical and mental development, and thyroid function. The best observation time for drug withdrawal should be 2 - 3 months. If T3, T4 and TSH levels are in the normal range, drug can be withdrawn safely. Once abnormal results were detected during follow-up, levothyroxine should be administrated continuously.

We report a case of neonatal thyrotoxicosis with concurrent respiratory failure in an infant born to a mother with Graves' disease and review the published literature describing neonatal hyperthyroidism. The male infant who was born by spontaneous delivery at 35 weeks of gestational age presented with fever, tachycardia and tachypnea at rest on day 11 after birth, and developed severe apnea on day 14. Thyroid function studies revealed hyperthyroidism in the infant, and his mother was confirmed to have Grave's disease during pregnancy. Literature review showed that among the 33 infants with similar conditions, tachycardia, tachypnea and poor weight gain were the most distinct clinical features of congenital hyperthyroidism. Accurate diagnosis of Graves' disease in the mother during pregnancy and awareness of the clinical presentations of neonatal hyperthyroidism are key to reducing missed diagnosis or misdiagnosis of neonatal hyperthyroidism.

Radioiodine activity required for remnant thyroid ablation is of great concern, to avoid unnecessary exposure to radiation and minimize adverse effects. We investigated clinical outcomes of remnant thyroid ablation with a low radioiodine activity in Korean patients with low to intermediate-risk thyroid cancer. For remnant thyroid ablation, 176 patients received radioiodine of 1.1 GBq, under a standard thyroid hormone withdrawal and a low iodine diet protocol. Serum levels of thyroid stimulating hormone stimulated thyroglobulin (off-Tg) and thyroglobulin-antibody (Tg-Ab), and a post-therapy whole body scan (RxWBS) were evaluated. Completion of remnant ablation was considered when there was no visible uptake on RxWBS and undetectable off-Tg (<1.0 ng/mL). Various factors including age, off-Tg, and histopathology were analyzed to predict ablation success rates. Of 176 patients, 68.8% (n = 121) who achieved successful remnant ablation were classified into Group A, and the remaining 55 were classified into Group B. Group A presented with significantly lower off-Tg at the first radioiodine administration (pre-ablative Tg) than those of Group B (1.2 +/- 2.3 ng/mL vs. 6.2 +/- 15.2 ng/mL, P = 0.027). Pre-ablative Tg was the only significant factor related with ablation success rates. Diagnostic performances of pre-ablative Tg < 10.0 ng/mL were sensitivity of 99.1%, specificity of 14.0%, positive predictive value of 71.1%, and negative predictive value of 87.5%, respectively. Single administration of low radioiodine activity could be sufficient for remnant thyroid ablation in patients with low to intermediate-risk thyroid cancer. Pre-ablative Tg with cutoff value of 10.0 ng/mL is a promising factor to predict successful remnant ablation.
