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.

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.

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.

Hypothyroidism can cause a variety of signs and symptoms of the neuromuscular system. However, ptosis in a patient with hypothyroidism is very rare. We report here on a case of central hypothyroidism that was due to Sheehan's syndrome and it manifested as bilateral ptosis in a 51-yr-old woman. She complained of exertional dyspnea and weakness. About 25-yr ago, she had a history of severe postpartum vaginal bleeding. The laboratory studies demonstrated hypopituitarism with secondary hypothyroidism. The ptosis was improved by replacement of thyroid hormone. Hypothyroidism should be considered in the differential diagnosis of patients who manifest with ptosis and that prompt replacement of hormone can lead to a complete recovery.

OBJECTIVETo observe the therapeutic effect of Xiehuo Yangyin powder (XHYY) in treating the initial stage of toxic and diffuse goiter (Graves' disease).

METHODSSixty patients were randomly divided into two groups, the treated group (n = 30) was treated with XHYY and methimazole, while the control group (n = 30) was treated with methimazole alone. The TCM syndrome score and thyroxin level in the two groups were compared and analyzed before, and 2 weeks, 12 weeks after treatment.

RESULTSThe syndrome score and thyroxin level in the treated group 2 weeks, 4 weeks, 12 weeks after treatment were reduced in comparing with before treatment, with the improvement better than those in the control group in the corresponding stages (P < 0.05).

CONCLUSIONThe Chinese herbal medicine XHYY plus methimazole, in treating Graves' disease, could rapidly and effectively improve the patients' clinical symptoms and lower the thyroxin level, reduce the daily taken of methimazole.

Combined pegylated interferon and ribavirin therapy for chronic hepatitis C infection cause a wide range of side effects, including flu-like syndrome, hematological abnormalities, cardiovascular symptoms, gastrointestinal symptoms, pulmonary dysfunction, depression, and retinopathy. Interferon-alpha has been shown to be related to the development of various autoimmune diseases, including systemic lupus erythematosus, rheumatoid arthritis, autoimmune thyroid disease, and type 1 diabetes mellitus (DM). Type 1 DM and thyroid disease respectively develop in 0.08~2.61% and 10~15% of patients treated with combined interferon-alpha and ribavirin for chronic hepatitis C. The coexistence of type 1 DM and autoimmune thyroiditis was rarely reported. We report a case of a 33-year-old female patient with chronic hepatitis C who simultaneously developed diabetic ketoacidosis and autoimmune thyroiditis after treatment with pegylated interferon-alpha 2b and ribavirin.

OBJECTIVETo compare differences in the intelligence and physical developmental levels of children with congenital hypothyroidism (CH) who received initial treatment at different times.

METHODSForty-nine children with CH diagnosed by neonatal screening between September 2008 and September 2011 were enrolled in this study. According to the timing of initial treatment with thyroid hormone, they were classified into two groups: <1 month and 1 to 3 months of life. At 6 months old, 1 year and 2 years old, their intelligence levels were evaluated by Gessell test. Their physical developmental levels were also measured. Their thyroid functions were examined with fluorescence immunoassay.

RESULTSWith treatment, there were no significant differences in thyroid hormones (FT3, FT4 and TSH) between the two groups (P>0.05) at 6 months old, 1 year and 2 years old. However, heights and weights in the <1 month treatment group were significantly higher than in the 1 to 3 months treatment group at all time points (P<0.05). At 6 months old, intelligence developmental levels in the <1 month treatment group were better than the 1 to 3 months treatment group (P<0.05) but significant differences were not noted at 1 and 2 years old (P>0.05).

CONCLUSIONSThe timing of initial treatment with thyroid hormone appears to be associated with the intelligence and physical development in children with CH. Treatment starting at less than 1 month of life contributes to improved physical and intelligence development compared with treatment starting at 1 to 3 months of life.

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.

Iodine-131 is a radioisotope that is routinely used for the treatment of differentiated thyroid cancer after total or near-total thyroidectomy. However, there is some evidence that iodine-131 can induce liver injury . Here we report a rare case of drug-induced liver injury (DILI) caused by iodine-131 in a patient with regional lymph node metastasis after total thyroidectomy. A 47-year-old woman was admitted with elevated liver enzymes and symptoms of general weakness and nausea. Ten weeks earlier she had undergone a total thyroidectomy for papillary thyroid carcinoma and had subsequently been prescribed levothyroxine to reduce the level of thyroid-stimulating hormone. Eight weeks after surgery she underwent iodine-131 ablative therapy at a dose of 100 millicuries, and subsequently presented with acute hepatitis after 10 days. To rule out all possible causative factors, abdominal ultrasonography, endoscopic ultrasonography (on the biliary tree and gall bladder), and a liver biopsy were performed. DILI caused by iodine-131 was suspected. Oral prednisolone was started at 30 mg/day, to which the patient responded well.
