Abnormalities in the relationship of paraoxonase 1 with HDL and apolipoprotein A1 and their possible connection to HDL dysfunctionality in type 2 diabetes

Blood-based bioenergetic profiling has promising applications as a minimally invasive biomarker of systemic bioenergetic capacity. In the present study, we examined peripheral blood mononuclear cell (PBMC) mitochondrial function and brain morphology in a cohort of African Americans with long-standing Type 2 diabetes. Key parameters of PBMC respiration were correlated with white matter, gray matter, and total intracranial volumes. Our analyses indicate that these relationships are primarily driven by the relationship of systemic bioenergetic capacity with total intracranial volume, suggesting that systemic differences in mitochondrial function may play a role in overall brain morphology.

The Relationship

Background: Type 2 diabetes mellitus is a metabolic disease that characterized by high blood sugar levels. This condition is often not noticed immediately and usually patient starting to realize it when complications have been occurred. A long-term complication of type 2 DM that occurred in men is erectile dysfunction (ED). ED is a condition when a person is unable to achieve or maintain an erection for sexual intercourse. One factor that influence the occurrence of ED and its severity in type 2 DM patients is the duration of the disease. Objective: The aim of this study was to determine the relationship of type 2 DM duration and the occurrence of ED. Methods: This study is an observational analytic cross-sectional study conducted at the Puskesmas (Public Health Center) Denpasar Barat I. The research data was obtained through medical record data and fill the International Index of Erectile Function (IIEF-5) questionnaire on 36 type 2 DM patients aged around 40-60 years. The statistical analysis used was Fisher's exact test. Results: The results showed that of the 36 samples, 19 (52.8%) samples had type 2 DM <24 months and 17 (47.2%) samples had type 2 DM >24 months. It was found that 5 (13.9%) samples did not experience ED while the rest experienced ED with different severity. There was a significant relationship between the type 2 DM duration and the occurrence of erectile dysfunction at Puskesmas Denpasar Barat I (p = 0.022). Conclusion: Study has found that type 2 DM patients with the longer duration (>24 months) have a higher occurrence of ED and tended to be more severe compared to those with shorter duration (<24 months). Further studies should be performed with higher number of patients and more controlled risk factor so it will be more accurate in determining the relationship between the duration of type 2 DM and ED.

Gender Specific

Type-2 diabetes (T2D) and its cardiovascular complications are related to sex. Increasing evidence suggests that paraoxonase 1 (PON1) activity, an antioxidant enzyme bound to high-density lipoproteins (HDL), is implicated in the onset and clinical progression of T2D. Since we previously showed that PON1 is a sexual dimorphic protein, we now investigated whether sex might impact the relationship between PON1 and this chronic disease. To address this aim, we assessed PON1 activity in the sera of 778 patients, including controls (women, n = 383; men, n = 198) and diabetics (women, n = 79; men = 118). PON1 activity decreased in both women and men with T2D compared with controls (p < 0.05 and p > 0.001, respectively), but the change was 50% larger in the female cohort. In line with this result, the enzyme activity was associated with serum glucose level only in women (r = −0.160, p = 0.002). Notably, only within this gender category, lower PON1 activity was independently associated with increased odds of being diabetic (odds ratio (95% Confidence interval: 2.162 (1.075–5.678)). In conclusion, our study suggests that PON1-deficiency in T2D is a gender-specific phenomenon, with women being more affected than men. This could contribute to the partial loss of female cardiovascular advantage associated with T2D.
