Introduction: Aging is often associated with decreased serum triiodothyronine levels. There is growing evidence that critical illness can cause thyroid dysfunction and nonthyroidal illness syndrome. Elderly patients with severe chronic obstructive pulmonary disease exacerbations may be more prone to thyroid function impairment. We evaluated nonthyroidal illness syndrome incidence in elderly patients with chronic obstructive pulmonary disease during severe exacerbations and the possible impact on short-term prognosis.
