A 43-year-old woman was diagnosed with thyroid storm due to Graves’ disease. Fever and inflammatory reactions were observed; however, the infectious focus was unclear. The patient was administered methimazole, potassium iodide, and meropenem. The presepsin levels increased and the fever persisted, but the C-reactive protein and procalcitonin (PCT) levels decreased. The meropenem and methimazole were discontinued, and propylthiouracil was initiated. The patient’s presepsin levels and thyroid function decreased; however, her fever continued. A total thyroidectomy was performed, and the patient’s fever improved while her presepsin and PCT levels normalized. Treatment with methimazole during thyroid storm may result in the secretion of presepsin without infection, which must be considered when diagnosing sepsis in patients with thyroid storm.
