Front Psychiatry 2022; 13:815196. [PMID: 35782452 PMCID: PMC9243435 DOI: 10.3389/fpsyt.2022.815196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Accepted: 05/27/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Depression is ubiquitous in patients with coronary artery disease (CAD). The relationship between depression and hemoglobin A1c (HbA1c) is controversial. The combined effect of high HbA1c and depression on prognosis is unclear, especially in non-diabetic CAD patients. We sought to explore these associations. METHODS 558 CAD patients were included in this prospective study. Patients were grouped by HbA1c levels and the status of clinical depression. The average follow-up period was about 2.2 years, and Cox proportional hazards models were used to compare the differences of prognosis in all the groups. RESULTS Clinical depression had no associations with HbA1c in all CAD patients (P for Pearson correlation = 0.74). In the all four groups, compared to group 1 (patients without clinical depression and low HbA1c), group 3 (without clinical depression and high HbA1c) had a higher risk of MACE (adjusted hazard ratio [aHR], 1.97; 95% confidence interval [CI], 1.2-3.25) and composite events (aHR, 1.67; 95% CI, 1.09-2.053). Group 4 (patients with clinical depression and high HbA1c) had higher HRs for MACE (aHR, 2.9; 95%CI, 1.32-6.38) and composite events (aHR, 2.12; 95% CI, 1.06-4.25). In CAD patients without diabetes, patients with clinical depression and high HbA1c had a higher risk of MACE (HR, 2.71; 95% CI, 1.02-7.19), non-cardiac readmission (HR,3.48; 95% CI, 1.26-9.57) and composite events (HR,2.44; 95% CI, 1.08-5.53) than those with no clinical depression and low HbA1c. In patients with comorbidities of depression and diabetes, patients with depression and high HbA1c more likely to experienced non-cardiac readmissions (HR, 4.49; 95% CI, 1.31-15.38) than patients with no depression and low HbA1c only. In all the above analysis, p-values for interaction between clinical depression and HbA1c were not statistically significant. CONCLUSIONS The presence of both depression and high HbA1c lead to a worse prognosis in CAD patients than one risk factor alone, no matter with or without the comorbidity of diabetes in these CAD patients. For patients with CAD and depression, lower HbA1c may be required.

Treatment-Induced Changes in Plasma Adiponectin Do Not Reduce Urinary Albumin Excretion in the Diabetes Prevention Program Cohort. PLoS One 2015; 10:e0136853. [PMID: 26312480 PMCID: PMC4551844 DOI: 10.1371/journal.pone.0136853] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2014] [Accepted: 08/07/2015] [Indexed: 12/15/2022] Open
Abstract
Background and Objectives Molecular data suggests that adiponectin may directly regulate urinary albumin excretion. In the Diabetes Prevention Program (DPP) we measured adiponectin and albuminuria before and after intervention, and we previously reported increases in adiponectin with interventions. Here we have used the DPP dataset to test the hypothesis that treatment-related increases in adiponectin may reduce albuminuria in obesity. Design, Setting, Participants and Methods We evaluated cross-sectional correlations between plasma adiponectin and urinary albumin excretion at baseline, and the relationship of treatment-related changes in adiponectin and albuminuria. Baseline and follow-up urine albumin to creatinine ratios (ACR (albumin to creatinine ratio)) and plasma adiponectin concentration were available in 2553 subjects. Results Adjusting for age, sex and race/ethnicity, we observed a statistically significant but weak inverse relationship between adiponectin and ACR at baseline (conditional Spearman’s rho = (-) 0.04, p = 0.04). Although DPP treatments significantly increased plasma adiponectin, there were no treatment effects on ACR and no differences in ACR across treatment groups. There was a weak direct (not inverse) association between change in adiponectin and change in albuminuria (adjusted Spearman’s rho = (+) 0.04, p = 0.03). Conclusions In a large, well-characterized cohort of obese dysglycemic subjects we observed a weak inverse association between circulating adiponectin concentrations and urinary albumin excretion at baseline. Contrary to the hypothesized effect, treatment-related increases in plasma adiponectin were not associated with a reduction in ACR. The association of change in adiponectin with change in ACR should be assessed in populations with overt albuminuria before excluding a beneficial effect of increasing adiponectin to reduce ACR in obesity.

Glycosylated hemoglobin A1c as a marker predicting the severity of coronary artery disease and early outcome in patients with stable angina. Lipids Health Dis 2014; 13:89. [PMID: 24884794 PMCID: PMC4070346 DOI: 10.1186/1476-511x-13-89] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2014] [Accepted: 05/13/2014] [Indexed: 02/07/2023] Open
Abstract
Background Glycosylated hemoglobin A1C (HbA1c) has been widely recognized as a marker for predicting the severity of diabetes mellitus (DM) and several cardiovascular diseases. However, whether HbA1c could predict the severity and clinical outcomes in patients with stable coronary artery disease (CAD) remains largely unknown. We determine relationship of HbA1c with severity and outcome in patients with stable CAD. Methods We enrolled 1433 patients with stable angina who underwent coronary angiography and were followed up for an average 12 months. The patients were classified into three groups by tertiles of baseline HbA1c level (low group <5.7%, n = 483; intermediate group 5.7 - 6.3%, n = 512; high group >6.3%, n = 438). The relationships between the plasma HbA1c and severity of CAD and early clinical outcomes were evaluated. Results High HbA1c was associated with three-vessel disease. Area under the receivers operating characteristic curve (AUC = 0.67, 95% CI: 0.63-0.71, P < 0.001) and multivariate logistic regression analysis suggested that HbA1C was an independent predictor of severity of CAD (OR = 1.60, 95% CI: 1.29-1.99, P < 0.001) even after adjusting for gender, age, risk factor of CAD, lipid profile and fasting blood glucose. During follow-up, 133 patients underwent pre-specified outcomes. After adjusting for multiple variables in the Cox regression model, HbA1C remained to be an independent predictor of poor prognosis (HR = 1.28, 95% CI: 1.12-1.45, P < 0.001). Conclusions We concluded that high level of baseline HbA1c appeared to be an independent predictor for the severity of CAD and poor outcome in patients with stable CAD.

Abstract
Background: Adiponectin, an adipocyte-derived hormone, is implicated in diabetes mellitus type 2 and atherosclerosis. The study was designed to investigate whether serum adiponectin levels in patients with both coronary artery disease (CAD) and diabetes mellitus type 2 (T2DM) are lower than in patients with CAD alone and control subjects. Objectives: In this present study, we measured serum adiponectin levels in consecutive CAD patients with and without T2DM and investigated whether decreased adiponectin is associated with risk factors of CAD. Materials and Methods: The study included 198 subjects, 138 patients with CAD (72 of whom had both CAD and T2DM), and 60 control subjects. We measured serum adiponectin, interleukin-6 (IL-6) and insulin by ELISA. In addition, Lipid profile, glucose and anthropometrical measurements were performed in all subjects. Results: The results revealed significant difference in serum adiponectin levels between patients with CAD+T2DM and patients with CAD alone (3.80 ± 1.52 vs. 5.25 ± 2.35, P = 0.007), between patients with CAD and control (5.25 ± 2.35 vs. 7.04 ± 3.32, P = 0.001), and between patients with CAD + T2DM and control (3.80 ± 1.52 vs. 7.04 ± 3.32, P < 0.001). Serum adiponectin level was significantly higher in women in contrast to men (5.97 ± 3.15 vs. 4.62 ± 2.81 µg/ml, P = 0.002). Serum adiponectin levels were correlated significantly with insulin (r = -0.178, P = 0.013), total cholesterol (r = -0.313, P < 0.001), low density lipoprotein (r = -0.154, P = 0.016), body mass index (r = -0.171, P = 0.016), glucose (r = -0.202, P = 0.006), HOMA-IR (r= -0.251, P = 0.001), and IL-6 levels (r = -0.321, P = 0.001). Adiponectin was correlated positively only with high density lipoprotein (r = 0.389, P < 0.001). Conclusions: It is speculated that increased insulin resistance and increase in other adipokines such as IL-6 may contribute to the decreased serum levels of adiponectin in patients with both CAD and T2DM.

Abstract
BACKGROUND Inflammation has been associated with insulin resistance, type 2 diabetes mellitus (T2DM), and atherothrombosis. AIM To determine differences in levels of proinflammatory and prothrombotic markers such as high sensitivity C-reactive protein (hs-CRP) and fibrinogen in subjects with normal glucose tolerance (NGT), prediabetes, and T2DM and to establish their relationship with other cardiovascular risk factors before clinical manifestations of cardiovascular disease. METHODS We conducted a nonrandomized, cross-sectional assay in a hospital at México City. The levels of hs-CRP and fibrinogen were measured and compared according to glucose tolerance status. RESULTS We enrolled 1047 individuals and they were distributed into NGT n = 473, pre-DM n = 250, and T2DM n = 216. There was a statistical difference between NGT and T2DM groups for fibrinogen (P = 0.01) and hs-CRP (P = 0.05). Fibrinogen and hs-CRP showed a significant positive correlation coefficient (r = 0.53, P<0.0001). In a multiple stepwise regression analysis, the variability in fibrinogen levels was explained by age, HbA1c, and hs-CRP (adjusted R² = 0.31, P<0.0001), and for hs-CRP it was explained by BMI and fibrinogen (adjusted R² = 0.33, P<0.0001). CONCLUSION Inflammation and prothrombotic state are present in people with T2DM lacking cardiovascular disease. Fibrinogen and Hs-CRP are positively correlated. Fibrinogen and hs-CRP concentrations are predominantly determined by BMI rather than glucose levels.

Acta Diabetol 2013; 50:333-40. [PMID: 22684266 DOI: 10.1007/s00592-012-0405-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2012] [Accepted: 05/03/2012] [Indexed: 12/18/2022]
Abstract
Type 2 diabetes mellitus is a risk factor for coronary artery disease (CAD). While there is a clear association of fasting plasma glucose (FPG) with microvascular complications, the risk for CAD conferred by FPG is relatively less clear. Therefore, we investigate the association between different FPG and the prevalence and severity of angiographic CAD in high-risk Chinese patients without known diabetes. Among 1,419 subjects who were to undergo coronary angiography for the confirmation of suspected myocardial ischemia, 906 subjects without known diabetes were included in this study and categorized into four groups according to the level of FPG: group 1, ≤5.5 mmol/l; group 2, 5.6-6.0 mmol/l; group 3, 6.1-6.9 mmol/l; and group 4, ≥7.0 mmol/l. Significant angiographic CAD was defined as ≥50 % lumen diameter reduction in at least one major coronary artery in a given subject. The severity and extent of coronary atherosclerosis were defined as the number of diseased vessels, the proportion of totally occluded vessel and the Gensini score. Associations between FPG and the prevalence and severity of CAD were assessed by logistic and linear stepwise regression analyses. The angiographic CAD prevalence, the number of diseased vessels, the totally occluded vessel, and the Gensini score increased corresponding to increasing FPG levels from ≤5.5 mmol/l to 5.6-6.0 mmol/l to 6.1-6.9 mmol/l to ≥7.0 mmol/l (P < 0.05). The FPG had significant association with angiographic CAD (adjusted OR, 1.53; 95 % CI, 1.19-1.98; P = 0.001) and the Gensini score (standardized regression coefficient = 0.172, P = 0.011). Compared with group 1, group 2, 3 and 4 demonstrated significantly higher CAD prevalence after adjustment (adjusted OR, 1.61 [1.16-2.19]; P = 0.015 for group 2; 1.49 [1.11-2.59]; P = 0.027 for group 3; and 4.19 [2.85-6.16]; P = 0.024 for group 4, respectively). FPG group was also significantly associated with the Gensini score (Standardized coefficients, 0.185; P = 0.007, respectively). FPG was an independent risk factor for the prevalence and severity of significant angiographic CAD in our study population. The severity of angiographic CAD increased along with the increasing FPG levels even in prediabetic state.

Abstract
INTRODUCTION Type 2 diabetes is a chronic disease associated to the presence of multiple risk factors. Among recently studied factors we cite PCR and micro-albumin. OBJECTIVE In the present study we intend to determine the correlation between urine albumin excretion rate, CRP levels and type of vascular complications in type 2 diabetes. PATIENTS AND METHODS We recruited 48 type 2 diabetic subjects subdivided into three groups according to the type of vascular complications (GI: type 2 diabetics without complications, GII: type 2 diabetics with microvascular complications and GIII: type 2 diabetics with macrovascular complications). RESULTS We found a significant elevated levels of CRP and micro-albumin (P<0.05) when we compared diabetics with vascular complications to those without any complications. Diabetics with macrovascular complications have the highest levels of CRP and micro-albumin. Significant positive correlation was found between CRP and micro-albumin levels in a total group of diabetics (r=0.32; P<0.05). CONCLUSION The determination of CRP and microalbumin levels represents an interest in the screening of cardiovascular disease in type 2 diabetics.

Abstract
We investigated the association between two single nucleotide polymorphisms (SNPs) in the adiponectin gene (rs822395 and rs266729) and coronary artery disease (CAD) in a case-control study of 198 unrelated Chinese CAD patients (with ≥ 70% coronary stenosis or previous myocardial infarction) and 237 non-CAD controls. The ligase reaction was used to detect SNPs rs822395 and rs266729, and the allelic association of these SNPs with the occurrence and severity of CAD was assessed. There were no significant differences in the genotypic or allelic frequencies of the two SNPs between control and CAD individuals. In addition, there was no association between the two SNPs and the severity of CAD based on the number of diseased vessels. The frequencies of alleles C and G at rs266729 differed significantly between females in the CAD and control groups, but not between males. Female carriers of allele G at rs266729 had a higher risk of CAD compared with allele C carriers (OR = 1.30, 95% CI: 1.09-2.64, p = 0.02). These results indicate a gender-specific effect of the adiponectin gene rs266729 variant in modulating the risk of CAD in women.

Abstract
INTRODUCTION Although polycystic ovary syndrome (PCOS) was described more than half a century ago, the underlying cause of PCOS is still unknown. The aim of our study was to evaluate whether serum resistin and adipocytokine levels alter and its changes relate with low grade inflammation in non-obese young women with PCOS. SUBJECTS AND METHODS Newly diagnosed 31 young non-obese women with PCOS (mean age 21.8 +/- 5.4 years; body mass index (BMI): 23.8 +/- 6.6 kg/m(2)) and 25 BMI- and age-matched, regular-cycling, healthy women (mean age 24.9 +/- 5.7 years; BMI: 23.1 +/- 5.8 kg/m(2)) were included the study Anthropometric measurements were evaluated. Resistin, adiponectin, glucose, insulin, hormone profiles, Lipoprotein (Lp)(a), high sensitive C reactive protein (hs-CRP), and homocysteine levels were measured in the beginning of oral glucose tolerance test. Homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. RESULTS Non-obese young women with PCOS had high adiponectin levels (28.01 +/- 6.47 ng/ml in PCOS vs. 23.89 +/- 7.70 ng/ml in control subjects, p = 0.034), whereas serum resistin levels were not significantly different compared with healthy controls (14.14 +/- 6.6 ng/ml in PCOS vs. 13.78 +/- 4.26 ng/ml in control subjects). There were no significant differences between two groups in terms of fasting insulin, Lp(a), homocysteine, and hs-CRP levels. Mean HOMA-IR value of patients with PCOS was similar with control subjects (1.93 +/- 0.73 in PCOS; 1.15 +/- 0.54 in control group). CONCLUSIONS Resistin levels did not change in non-obese young women with PCOS whereas adiponectin level in non-obese young women with PCOS was significantly higher than control subjects, perhaps, because of no insulin resistance. Circulating resistin levels may not be candidate to play a role in pathogenesis of PCOS without insulin resistance or obesity.
