The NS group showed higher thyroid-stimulating hormone and lower free hormones, corresponding to a higher frequency of both euthyroid sick syndrome {ESS; 36% versus 5%; odds ratio [OR] 10.6 [95% confidence interval (CI) 2.2\u201350.0]} and hypothyroidism [31% versus 5%; OR 8.5 (95% CI 1.8\u201340.7)] compared with the control group. Levothyroxine supplementation was required for 11 NS patients (26% of the NS group). In addition, compared with control individuals, NS patients exhibited lower lean tissue mass and a trend towards hypercoagulability, which was evidenced by higher levels of most coagulation factors and fibrinolysis inhibitors, and reduced endogenous anticoagulants activities. Furthermore, NS patients with ESS presented with a 10.4\u00a0kg (95% CI \u221218.68 to \u22122.12) lower lean tissue mass. Those with hypothyroidism had significantly reduced activity of coagulation factor X [by \u221230% (95% CI \u221247 to \u221213)] and protein S [by \u221227% (95% CI \u221241 to \u221213)] compared with euthyroid NS individuals.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Thyroid dysfunction is common in severe NS, often necessitating levothyroxine supplementation, which supports routine thyroid workup.
