There is controversy on the treatment of subclinical hypothyroidism (SCH). While a number of guidelines from professional societies recommend treatment of SCH based on TSH levels, age, and presence of comorbidities, a recent guideline issued a recommendation against thyroid hormone treatment in adults with SCH. In this debate article, we explore this controversy by presenting two points of view about SCH and its treatment. Treatment of patients who are pregnant or trying to become pregnant will not be discussed.

Objectives: Thyroid disorders are among the common endocrine problems in pregnant women. It is now well established that not only overt but subclinical thyroid dysfunction also has adverse effects on maternal and fetal outcome. There are few data from Bangladesh about the prevalence of thyroid dysfunction in pregnancy. With this background, this study aims to find out thyroid dysfunction (both overt and subclinical hypothyroidism) in pregnancy and its impact on obstetrical outcome.Methods: We studied the evaluation of 50 admitted pregnancies corresponding to 29 women with subclinical hypothyroidism and rest 21 was overt hypothyroidism. Detailed history and examination were performed. Apart from routine obstetrical investigations, Thyroid Stimulating Hormone (TSH) estimation was done. Their obstetrical and perinatal outcomes were noted.Results: Overt hypothyroidism was significantly (p<0.05) higher in 25 to 44 years age group. However two and three abortions were significantly (p<0.05) higher in overt hypothyroidism patients. In sub clinical hypothyroidism 86.2% conceived firstly within 2 years and 66.7% in overt hypothyroidism patients conceived firstly in between 3 to 5 years after marriage. Overt hypothyroids were prone to have pregnancy-induced hypertension 42.9%, intrauterine growth restriction (P=0.001) and gestational diabetes (38.1%) as compared to subclinical cases. Neonatal complications were significantly more in overt hypothyroidism group. Mean TSH level was significantly (p<0.05) higher in overt hypothyroidism patients but mean FT4 level was almost similar in both groups. Majority of the patient underwent caesarean section in both groups due to associated medical and obstetrical complications. None of the babies showed hypothyroidism by cord blood tests. In this analysis our results showed that overt hypothyroidism among Bangladeshi pregnant women are associated with more maternal complication & adverse parental outcome than subclinical hypothyroidism. The adequate treatment of hypothyroidism during gestation minimizes risks and generally, makes it possible for pregnancies to be carried to term without complications. Significant adverse effects on maternal and fetal outcome were seen emphasizing the importance of routine antenatal thyroid screening.Bangladesh Med Res Counc Bull 2014; 40 (2): 52-57

Abstract. Basal serum TSH and the peak TSH response to a 500 μg TRH bolus were measured in 57 euthyroid and in 29 hypothyroid subjects either receiving graded thyroid hormone replacement or acutely removed from full replacement therapy. Serum TSH, total T4 and T3 were determined by sensitive radioimmunoassay methods. The peak versus basal TSH data for hypothyroid patients were linear within individuals. The regression slope of the peak versus basal TSH data for all hypothyroid subjects did not differ significantly from the corresponding slope for all euthyroid subjects. Basal and peak TSH versus T3 and T4 data for hypothyroid patients were also linear within each individual. Moreover, the regression of the basal TSH values averaged over the non-replacement to full replacement state against the TSH versus T3 slope had a significant negative correlation. This trend leads to an array of regression lines which average to the familiar hyperbolic relationship between thyrotrophin and thyroid hormone levels in man.

AbstractThyroid hormone reference intervals are crucial for diagnosing and monitoring thyroid dysfunction during early pregnancy, and the dynamic change trend of thyroid hormones during pregnancy can assist clinicians to assess the thyroid function of pregnant women. This study aims to establish early pregnancy related thyroid hormones models and reference intervals for pregnant women. We established two derived databases: derived database* and derived database#. Reference individuals in database* were used to establish gestational age-specific reference intervals for thyroid hormones and early pregnancy related thyroid hormones models for pregnant women. Individuals in database# were apparently healthy non-pregnant women. The thyroid hormones levels of individuals in database# were compared with that of individuals in database* using nonparametric methods and the comparative confidence interval method. The differences in thyroid stimulating hormone and free thyroxine between early pregnant and non-pregnant women were statistically significant (p<0.0001). The reference intervals of thyroid stimulating hormone, free thyroxine and free triiodothyronine for early pregnant women were 0.052–3.393 μIU/ml, 1.01–1.54 ng/dl, and 2.51–3.66 pg/ml, respectively. Results concerning thyroid stimulating hormone and free thyroxine reference intervals of early pregnancy are comparable with those from other studies using the same detection platform. Early pregnancy related thyroid hormones models showed various change patterns with gestational age for thyroid hormones. Early pregnancy related thyroid hormones models and reference intervals for pregnant women were established, so as to provide accurate and reliable reference basis for the diagnosing and monitoring of maternal thyroid disfunction in early pregnancy.

Specific Mrna

The modulation of expression of the skeletal muscle and erythrocyte acylphosphatase isoenzymes by thyroid hormone has been investigated. Our results indicate a differential regulation of the two enzymic isoforms by tri-iodothyronine (T3) in K562 cells in culture: an increase in the specific mRNA during T3-stimulation is shown only for the skeletal muscle isoenzyme. A fast and transient T3 induction of the accumulation of the specific mRNA can be observed, reaching a maximum 8 h after hormone treatment and then rapidly decreasing almost to the steady-state level after 24 h. A nuclear run-on assay was performed to explore the mechanisms of this regulation. These studies indicate that T3 induction of skeletal muscle acylphosphatase mRNA is due, at least in part, to a fast and transient increase in the rate of gene transcription, within 4 h after hormone administration. A very rapid decrease is then observed within a further 2 h. T3-dependent accumulation of the mRNA for the skeletal muscle acylphosphatase requires ongoing protein synthesis, as confirmed by inhibition with cycloheximide or puromycin. These findings indicate that the transcriptional regulation of the gene may be indirect.
