Key result
In non-diabetic individuals, circulating full-length ANGPTL8 concentrations were significantly elevated in patients with dyslipidemia and positively associated with serum non-HDL-C levels (β 0.050).

In non-diabetic Chinese individuals, circulating full-length ANGPTL8 is significantly elevated in those with dyslipidemia and positively correlates with non-HDL-C levels, suggesting a role in lipid metabolism.
ANGPTL8 elevation in non-diabetic dyslipidemia is hypothesis-generating; leaves open causal role or biomarker utility pending longitudinal data.
BACKGROUND: Angiopoietin-like protein 8 (ANGPTL8) is a novel hormone involved in the regulation of lipid metabolism and glucose homeostasis. There are inconsistent results regarding the association between ANGPTL8 and lipids in humans. We aimed to investigate the associations between ANGPTL8 and lipids in people without diabetes. METHODS: This was a cross-sectional study of 107 patients with dyslipidemia and 141 patients without. Dyslipidemia diagnosis was based on Chinese guidelines for the prevention and treatment of dyslipidemia in adults. Total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol (HDL-C) were examined. Non-HDL-C was calculated by subtracting HDL-C from TC. Circulating full-length ANGPTL8 concentrations were measured using enzyme-linked immunosorbent assay. Associations between log-transformed circulating full-length ANGPTL8 and serum lipids were examined using multivariate linear regression analysis. RESULTS: Circulating ANGPTL8 concentrations were significantly elevated in patients with dyslipidemia compared with patients without dyslipidemia. Circulating full-length ANGPTL8 concentrations were positively associated with non-HDL-C, TG and TC levels after adjusting for age, gender, body mass index, high-sensitivity C-reactive protein, alanine aminotransferase, and creatinine. CONCLUSION: In people without diabetes, circulating full-length ANGPTL8 concentrations in patients with dyslipidemia were significantly elevated compared with non-dyslipidemia, and ANGPTL8 was positively associated with serum non-HDL-C levels.

Yang et al. (2018) conducted a cross-sectional in Dyslipidemia (n=248). Circulating full-length ANGPTL8 concentrations vs. Non-dyslipidemia was evaluated on Association between log-transformed ANGPTL8 and non-HDL-C (adjusted) (β 0.050, 95% CI 0.020-0.079, p=<0.001). In non-diabetic individuals, circulating full-length ANGPTL8 concentrations were significantly elevated in patients with dyslipidemia and positively associated with serum non-HDL-C levels (β 0.050).
