Euthyroid sick syndrome in trauma patients with severe inflammatory response syndrome / 中华创伤杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the alternations of thyroid hormone in traumatic patients with severe inflammatory response syndrome (SIRS).</p><p><b>METHODS</b>Fifty traumatic patients with severe SIRS were enrolled and divided into two groups according to whether they presented multiorgan dysfunction syndrome (MODS). Thyroid hormone measurements were taken, including total triiodothyronine (TT3), total thyroxine (TT4), free triiodothyronine (FT3), free thyroxine (FT4) and thyroid stimulating hormone (TSH). The acute physiology and chronic health evaluation II (APACHE II) score was calculated according to clinical data. The outcomes of recovery or deterioration were recorded, as well as the length of time from the onset of SIRS to the time thyroid hormones were measured.</p><p><b>RESULTS</b>Euthyroid sick syndrome (ESS) was presented in 45 cases. TT3 level was negatively correlated with APACHE II score (r = -0.330, P<0.05), and TT3/TT4 value was negatively correlated with the duration of SIRS( r = -0.316, P<0.05). TT3, TT4 and FT3 levels in MODS patients were significantly lower than those without MODS (P<0.05). MODS patients got low TT4 or FT4 level more frequently than those without MODS (P<0.05). Compared with the patients in normal TSH group, the patients with decreased TSH had lower T3, T4, recovery rate and higher APACHE II scores, MODS incidence, but there was no difference between two groups (P>0.05).</p><p><b>CONCLUSIONS</b>Trauma patients with severe SIRS have high possibility to get ESS, which occurs more frequently and severely in MODS patients. It shows the influences of SIRS on the thyroid axes. With the persistence and aggravation of SIRS, there is a progressive reduction of thyroid hormone.</p>
