Abstract

During illness, major changes in thyroid hormone metabolism and regulation occur; these are collectively known as non-thyroidal illness and are characterized by decreased serum triiodothyronine (T(3)) and thyroxine (T(4)) without an increase in serum TSH. Whether alterations in the central part of the hypothalamus-pituitary-thyroid (HPT) axis precede changes in peripheral thyroid hormone metabolism instead of vice versa, or occur simultaneously, is presently unknown. We therefore studied the time-course of changes in thyroid hormone metabolism in the HPT axis of mice during acute illness induced by bacterial endotoxin (lipopolysaccharide; LPS).LPS rapidly induced interleukin-1beta mRNA expression in the hypothalamus, pituitary, thyroid and liver. This was followed by almost simultaneous changes in the pituitary (decreased expression of thyroid receptor (TR)-beta2, TSHbeta and 5'-deiodinase (D1) mRNAs), the thyroid (decreased TSH receptor mRNA) and the liver (decreased TRbeta1 and D1 mRNA). In the hypothalamus, type 2 deiodinase mRNA expression was strongly increased whereas preproTRH mRNA expression did not change after LPS. Serum T(3) and T(4) fell only after 24 h.Our results suggested almost simultaneous involvement of the whole HPT axis in the downregulation of thyroid hormone metabolism during acute illness.

  • Illness results in marked downregulation of liver DIO1 both in humans and experimental animals.

    “Illness results in marked downregulation of DIO1 both in humans and experimental animals [15, 20, 21].”

    From An update on non-thyroidal illness syndrome (2021) · cites this paper as [15]

    The Liver and circulation section reports decreased liver D1 mRNA expression and activity after LPS administration in mice, supporting the experimental-animal part of the claim. The paper’s discussion of human illness concerns the hypothalamus, not liver D1, so this source does not support the human part. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Liver TRα and TRβ expression in rodents decrease during acute illness but not during chronic inflammation and bacterial sepsis.

    “Liver TRα and TRβ expression in rodents decrease during acute illness [15, 39] but not during chronic inflammation and bacterial sepsis.”

    From An update on non-thyroidal illness syndrome (2021) · cites this paper as [15]

    The Liver and circulation section reports decreased liver TR1 mRNA within eight hours of LPS administration in mice, supporting a decrease in one liver receptor transcript during acute illness. It does not report decreases in both liver TRα and TRβ. The citation precedes the chronic-inflammation and bacterial-sepsis clause, so that clause is not attributed to this source. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Illness results in increased hypothalamic DIO2 mRNA expression and activity while hypothalamic DIO3 decreases.

    “Illness results in increased DIO2 mRNA expression and activity [12, 15–17] while hypothalamic DIO3 decreases [18, 19].”

    From An update on non-thyroidal illness syndrome (2021) · cites this paper as [15]

  • Liver TRβ1 expression decreases during acute inflammation in mice and limited availability of SRC-1 might be partly responsible for the illness induced decrease of liver DIO1.

    “Indeed, liver TRβ1 expression decreases during acute inflammation in mice [15, 39, 77] and limited availability of SRC-1, a shared coactivator for TR and inflammatory signaling pathways, might be partly responsible for the illness induced decrease of liver DIO1 [78, 79].”

    From An update on non-thyroidal illness syndrome (2021) · cites this paper as [15]

  • The whole HPT axis is involved almost simultaneously in the downregulation of thyroid hormone metabolism during acute illness.

    “Together, this suggested almost simultaneous involvement of the whole HPT axis in the downregulation of thyroid hormone metabolism during acute illness [15].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
