Lipid profiles and hypertriglyceridemia among transgender and gender diverse adults on gender-affirming hormone therapy.

BACKGROUND: The effects of gender-affirming hormone therapy on lipid profiles among transgender adults have been inconsistent and incompletely characterized. OBJECTIVE: To longitudinally assess changes to lipid profiles following hormone therapy and to establish prevalence rates of hyperlipidemia/low HDL-cholesterol. METHODS: This longitudinal study followed lipid profiles of 366 transgender and gender-diverse adult patients (170 transfeminine and 196 transmasculine; mean age, 28 years) in Washington DC USA. Lipid profiles were measured at baseline and at multiple follow-up clinical visits up to 57 months after the initiation of hormone therapy. RESULTS: Within 2-10 months of starting gender-affirming hormone therapy, mean levels of HDL-cholesterol decreased by 16% in transmasculine individuals and increased by 11% in transfeminine individuals. Over the study, mean triglyceride levels increased by 26-37% in the transmasculine group. Over the study, the prevalence of moderate hypertriglyceridemia (175-499 mg/dL) ranged from 11 to 32% in the transfeminine group and 6-19% in the transmasculine group. Severe hypertriglyceridemia (≥500 mg/dL) was only observed in one individual. On hormone therapy, 24-30% of the transfeminine group had a HDL-cholesterol < 50 mg/dL and 16-24% of the transmasculine group had a HDL-cholesterol < 40 mg/dL. LDL-cholesterol levels ≥160 mg/dL were rare among both groups. CONCLUSIONS: In a gender-diverse population on hormone therapy, low HDL-cholesterol and moderate hypertriglyceridemia were relatively common. HDL-cholesterol decreased with testosterone therapy and increased with a combination of oral estrogen and spironolactone. Testosterone use was associated with an increase in triglycerides. Our data support the recommendation to routinely monitor lipid profiles in gender-diverse patients on GAHT.

Financial Conflicts of Interest Among Authors of Endocrine Society Clinical Practice Guidelines.

Context: There has been a proliferation of clinical practice guidelines in endocrinology and a coincident increased interest in transparency regarding relationships between physicians and industry. Evidence Acquisition: We collected self-reported disclosures and Open Payments data for 169 authors of 26 clinical practice guidelines published between 2010 and 2017 by the Endocrine Society. Conflicts of interest in which pharmaceutical and device companies manufactured drugs or products pertinent to an author's specific clinical practice guideline(s) were deemed relevant. Open Payments data were grouped into research and nonresearch (consultancies, honoraria, travel, food) categories. Evidence Synthesis: We compared the policies of the Endocrine Society regarding seven conflict of interest recommendations issued by the National Academy of Medicine in 2011. Conclusion: Relevant nonresearch financial conflicts of interest were self-reported by 42% of authors of clinical practice guidelines. Open Payments were recorded for 74% (84 of 113) of US authors between 2013 and 2016. Payments to 84 US authors totaled $5.5 million for nonresearch activities and $30.9 million for research. The nonresearch payments were divided into consulting (46%), honoraria (26%), travel (25%), and food (3%). The Endocrine Society partially follows the National Academy of Medicine recommendations to limit conflicts of interest. Readers should be aware of how clinical practice guidelines are developed and the policies of the organizations and journals that publish them. Professional societies and journal editors should strive to ensure that their policies and practices promote objective and unbiased clinical practice guidelines.
