It's "critically important" for clinicians to recognize that not all patients with hypothyroidism are fully treated with levothyroxine (LT4) and some may need combination treatment with triiodothyronine (LT3) despite normal levels of thyroid stimulating hormone (TSH), according to thyroid expert Antonio C. Bianco, MD, PhD.
Speaking to a crowded room at the recent American Association of Clinical Endocrinology (AACE) Annual Meeting 2022, Bianco summarized the history of thyroid replacement treatment, the emerging data focusing on the subset of patients remaining symptomatic on levothyroxine, and how the clinical guidelines have evolved from stating that LT4 is the one and only treatment to now acknowledging that some patients may need combination therapy.
