Abstract
To describe the first documented case of subacute (De Quervain) thyroiditis in the course of novel H1N1 influenza infection. This is a case report of a patient diagnosed at the General Hospital "G. Hatzikosta" of Ioannina, Greece. A 55-year-old previously healthy male developed an influenza-like syndrome that was accompanied by severe neck pain, palpitations, weight loss, and disproportionately increased erythrocyte sedimentation rate. Polymerase chain reaction assay of pharyngeal swabs confirmed the diagnosis of novel H1N1 influenza infection. Serum thyroid-stimulating hormone was suppressed to zero and levels of free thyroxine and particularly triiodothyronine were increased. Technetium-99m-pertechnetate scintigraphy showed diffuse and inhomogeneous very low technetium trapping. The patient was treated with non-steroidal anti-inflammatory drugs and thyroid function gradually normalized without evolving to a hypothyroid phase. This is the first case of subacute thyroiditis associated with novel H1N1 influenza infection. Furthermore, this is the first case to definitely demonstrate active influenza infection of any type concurrent with thyroiditis, and one of the very rare similar cases for any active viral disease etiologically implicated in the pathogenesis of subacute thyroiditis.
