Thyroid Microsomal Antibodies

Abstract. In sera from 1643 randomly selected blood donors examined in 1979 thyroglobulin antibodies (TGA) were found in 3.4% and thyroid microsomal antibodies (TMA) in 7.0%. TMA, but not TGA, showed significant sex and age relationships. Eighty-two donors with TMA titres ≥ 1600 and/or TGA titres ≥ 128 were available for a follow-up study in 1982. In 69 of these with TMA there was a significantly increased incidence of pathological thyroid function-test values (T4, T3 and TSH) as compared to age- and sexmatched donors without thyroid antibodies. In this group 9 individuals had overt and three latent hypothyroidism, two individuals were found with symptomless autoimmune thyroiditis and one with a non-toxic nodular goitre. Only 2 of these had been diagnosed before 1982, and none recognized before 1979. In addition, the group contained 9 individuals who had been treated because of hyperthyroidism, all except one before 1979. The likelihood of detecting a previously unrecognized hypothyroidism increased with increasing TMA titre. In contrast, the 24 donors with TGA did not show an increased frequency of pathological thyroid function-test- values in 1982.

Thyroid Microsomal Antibodies

Abstract. Eighteen patients with juvenile autoimmune thyroiditis were studied. At diagnosis 8 (44%) of the patients were euthyroid and 10 hypothyroid, whereas at the end of 6 to 12 months follow-up, 12 (66%) were euthyroid and 6 hypothyroid. All the patients were HLA-typed. The frequency of HLA-DR4 was increased in the patients when compared with the normal population, 63 vs 28% (p < 0.01). An analysis of thyroid-infiltrating mononuclear cells revealed that the majority of the thyroid-infiltrating lymphocytes were T cells. More T lymphocytes and fewer B lymphocytes and HLA class II positive lymphocytes were found among the thyroid-infiltrating mononuclear cells in euthyroid than hypothyroid patients. The numbers of thyroid-infiltrating B lymphocytes correlated with the levels of thyroid microsomal antibodies. No correlation was found between thyroid function and thyroid antibodies.

Abstract. Some studies have reported inaccuracy of predicting basal metabolic rate (BMR) by using common equations for Asian people. Thus, this study was undertaken to develop new predictive equations for the Iranian community and also to compare their accuracy with the commonly used formulas. Anthropometric measures and thyroid function were evaluated for 267 healthy subjects (18–60 y). Indirect calorimetry (InCal) was performed only for those participants with normal thyroid function tests (n = 252). Comparison of predicted RMR (both kcal/d and kcal.kg.wt−1.d−1) using current predictive formulas and measured RMR revealed that Harris-Benedict and FAO/WHO/UNU significantly over-estimated and Mifflin-St. Jeor significantly under-estimated RMR as compared to InCal measurements. In stepwise regression analysis for developing new equations, the highest r2 (=0.89) was from a model comprising sex, height and weight. However, further analyses revealed that unlike the subjects under 30 y, the association between age and the measured RMR in subjects 30 y and plus was negative (r = −0.241, p = 0.001). As a result, two separate equations were developed for these two age groups. Over 80 percent of variations were covered by the new equations. In conclusion, there were statistical significant under- and over-estimation of RMR using common predictive equations in our subjects. Using the new equations, the accuracy of the calculated RMR increased remarkably.
