摘要

Small nerve fibre damage and cardiac autonomic dysfunction in patients with hypertriglyceridaemia

Background & objectives

Hypertriglyceridaemia (HTG) is an independent risk factor for small fibre neuropathy in patients with type 1, type 2 diabetes, and obesity. This study assessed for evidence of small nerve fibre damage and cardiac autonomic dysfunction in individuals with HTG, without diabetes.

Methods

Participants with HTG (n=60) and age and sex-matched controls (n=31) underwent assessment of the lipid profile, neuropathic symptoms and disability, corneal confocal microscopy (CCM) and cardiac autonomic nerve function tests.

Results

Triglyceride (TG) concentration was significantly higher [6.0 (3.6–8.7) vs 1.1 (0.7–1.4) mmol/L, p < 0.001], and HDL-C [0.9 (0.7–1.2) vs 1.5 (1.3–1.8) mmol/L, p < 0.001) was lower in the HTG group. The Neuropathy Symptom Profile score [2 (0–5) vs 0, p < 0.001], Neuropathy Disability Score [2 (0–3) vs 0, p < 0.001] and vibration perception threshold [8.9 (5.5–10.5) vs 3.0 (2.0–4.0) volts, p < 0.001] were higher, whilst corneal nerve fibre density (CNFD) [28.9 (5.9) vs 35.1 (7.2) no./mm², p < 0.001], corneal nerve branch density (CNBD) [50.0 (30.4–66.5) vs 76.1 (56.2–112.5) no./mm², p < 0.001], corneal nerve fibre length (CNFL) [19.8 (4.8) vs 26.0 (6.2) mm/mm², p < 0.001], deep breathing heart rate variability (DB–HRV) [18 (13–20) vs 25 (20–30) beats/min, p < 0.001], E−I ratio [1.13 (1.09–1.20) vs 1.25 (1.18–1.31), p < 0.001], valsalva ratio [1.29 (1.18–1.49) vs. 1.47 (1.28–1.59), p = 0.01] and 30–15 ratio [1.24 (1.16–1.36) vs. 1.40 (1.27–1.49), p = 0.002] were lower in the HTG group compared to controls. Serum TG concentration correlated negatively with CCM parameters and cardiac autonomic function tests.

Conclusion

HTG, independent of diabetes, is associated with signs and symptoms of neuropathy, small nerve fibre damage and cardiac autonomic dysfunction.

期刊介绍： Atherosclerosis has an open access mirror journal Atherosclerosis: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Atherosclerosis brings together, from all sources, papers concerned with investigation on atherosclerosis, its risk factors and clinical manifestations. Atherosclerosis covers basic and translational, clinical and population research approaches to arterial and vascular biology and disease, as well as their risk factors including: disturbances of lipid and lipoprotein metabolism, diabetes and hypertension, thrombosis, and inflammation. The Editors are interested in original or review papers dealing with the pathogenesis, environmental, genetic and epigenetic basis, diagnosis or treatment of atherosclerosis and related diseases as well as their risk factors.
