Background: Single-nucleotide polymorphisms (SNPs) allow us to study effects of genetic variation on thyroid hormone levels. Phosphodiesterase 8B (PDE8B) is a protein responsible for cAMP generation, found in thyroid and brain tissue, but not normal pituitary tissue. Variation at this locus has been reported to influence TSH levels, but its effect on T3 and T4 had not been studied in the general population. Deiodinase 1 (DIO1) is known to influence T...

Section 1: Case history: A 50-year-old woman presented to the HIV clinic after suspecting adverse effects following two intra-articular triamcinolone injections to her left hip, administered three and seven months prior. She complained of ongoing leg pain, generalised weakness and lethargy. Her past medical history included HIV infection, mild asthma for which she took inhalers only and had never required oral steroids. Her antiretroviral medications included dolutegravir, dar...

Background and Objective: Thyroid function reference ranges are statistically defined by the 2.5th and 97.5th percentiles, which do not account for potential risk of clinical outcomes. We aimed to define the optimal ranges of thyroid-stimulating hormone (TSH) and free thyroxine (FT4), based on the risk of cardiovascular disease (CVD) and mortality.Methods: We performed an individual-participant data analysis and identified prospecti...
