Introduction. A neuroimmune communication exists, and compelling evidence suggests that diabetic neuropathy and systemic inflammation are linked. Our aims were (1) to investigate biomarkers of the ongoing inflammation processes including cytokines, adhesion molecules, and chemokines and (2) to associate the findings with cardiovascular autonomic neuropathy in type 1 diabetes by measuring heart rate variability and cardiac vagal tone. Materials and Methods. We included 104 adults with type 1 diabetes. Heart rate variability, time domain, and frequency domains were calculated from a 24-hour Holter electrocardiogram, while cardiac vagal tone was determined from a 5-minute electrocardiogram. Cytokines (interleukin- (IL-) 1α, IL-4, IL-12p70, IL-13, IL-17, and tumor necrosis factor- (TNF-) α), adhesion molecules (E-selectin, P-selectin, and intercellular adhesion molecule- (ICAM-) 1), and chemokines (chemokine (C-C motif) ligand (CCL)2, CCL3, CCL4, and C-X-C motif chemokine (CXCL)10) were assessed using a Luminex multiplexing technology. Associations between concentrations of inflammatory biomarkers and continuous variables of heart rate variability and cardiac vagal tone were estimated using multivariable linear regression adjusting for age, sex, disease duration, and smoking. Results. Participants with the presence of cardiovascular autonomic neuropathy had higher systemic levels of IL-1α, IL-4, CCL2, and E-selectin than those without cardiovascular autonomic neuropathy. IL-1α, IL-4, IL-12, TNF-α, and E-selectin were inversely associated with both sympathetic and parasympathetic heart rate variability measures (p>0.01). Discussion. Our results show that several pro- and anti-inflammatory factors, believed to be involved in the progression of diabetic polyneuropathy, are associated with cardiovascular autonomic neuropathy, suggesting that these factors may also contribute to the pathogenesis of cardiovascular autonomic neuropathy. Our findings emphasize the importance of the neuroimmune regulatory system in the pathogenesis of neuropathy in type 1 diabetes.

Diabetic Cardiovascular Autonomic Neuropathy

Abstract   Diabetic cardiovascular autonomic neuropathy (CAN) encompasses damage to the autonomic nerve fibers innervating the heart and blood vessels, resulting in abnormalities in heart rate control and vascular dynamics. Clinical symptoms associated with CAN include resting tachycardia, postural hypotension, dizziness, syncope, exercise intolerance, silent myocardial infarction. The earliest finding of CAN, even at the subclinical stage, is a decrease in heart rate variability (HRV) Purpose To study CAN prevalence and understand the diagnostic capabilities of HRV - tests of diabetic cardiovascular autonomic neuropathy in children with type 1 diabetes. Methods 100 children with type 1 diabetes were assessed for CAN (age 15.2 yrs [9.0–17.8], duration 6.5 yrs [4.0–10.6], HbA1c 8.1% 6.3–9.7]). The degree of compensation of diabetes was estimated according to criteria ISPAD Consensus Guidelines, 2018. Optimal level (HbA1c <7.0%) of compensation was revealed in 62% of children (group I) and nonoptimal in 38% of children (group II). For evaluation of the CAN we used HRV - tests: RR 30:15 ratio, ΔRR quiet breath, ΔRR deep breath, BP response to standing. Results Diabetic cardiovascular autonomic neuropathy was diagnosed in 41 children: in group I – in 6 (29%) and in group II – 35 (71%) children (p=0.00001). The prevalence of DCN correlated with HbA1c level in children and adolescents (groups I and II): ΔRR quiet breath r=−0.47 & r=−0.9; ΔRR deep breath r=−0.65 & r=−0.85; RR30:15 r=−0.77 & r=−0.88 respectively. Prevalence of CAN increased parallel to type 1 diabetes duration (p<0.01). Conclusions Diabetic cardiovascular autonomic neuropathy in children with type 1 diabetes was diagnosed in 41%. Prevalence of diabetic cardiovascular autonomic neuropathy increases parallel to type 1 diabetes duration (p<0.01). In this study we found an association between HRV indexes and HbA1c level. This provides support for HRV - testing to assess diabetic cardiovascular autonomic neuropathy in children. Funding Acknowledgement Type of funding source: None
