Depressive symptoms and carotid intima-media thickness in South American Hispanics: results from the PREVENCION study

The association between liver fibrosis and depression in patients after ischemic stroke

BACKGROUND AND OBJECTIVE

Liver fibrosis has been considered a predictor of cardiovascular disease. This study aimed to evaluate whether the degree of liver fibrosis is related to post-stroke depression (PSD) at 3 months follow-up.

METHODS

We prospectively and continuously enrolled patients with first-ever ischemic stroke from June 2020 to January 2022. Liver fibrosis was measured after admission by calculating the Fibrosis-4 index (FIB-4) and stratified into two categories (< 2.67 versus ≥ 2.67). Patients with a 17-item Hamilton Depression Scale score > 7 were further evaluated using the Chinese version of the structured clinical interview of DSM-IV, for diagnosing PSD at 3 months.

RESULTS

A total of 326 patients (mean age 66.6 years, 51.5% male) were recruited for the study. As determined by the FIB-4 score, 80 (24.5%) patients had advanced liver fibrosis. During the follow-up, PSD was observed in 91 patients, which accounted for 27.9% (95% confidence interval [CI] 25.5%-30.5%) of the cohort. The prevalence of advanced liver fibrosis was higher in PSD patients than those without PSD (40.0% versus 24.0%; P = 0.006). After adjustment for covariates in the multivariate logistic analysis, advanced fibrosis was significantly associated with PSD (odds ratio [OR], 1.88; 95% CI, 1.03-3.42; P = 0.040). Similar results were found when the FIB-4 was analyzed as a continuous variable.

CONCLUSIONS

This study found that advanced liver fibrosis was associated with an increased risk of 3-month PSD. FIB-4 score may be valuable for screening depressive symptoms in ischemic stroke patients.

Sociodemographic moderation of the association between depression and stroke incidence in a retrospective cohort of 0.4 million primary care recipients with hypertension

BACKGROUND

Previous research has suggested an association between depression and subsequent acute stroke incidence, but few studies have examined any effect modification by sociodemographic factors. In addition, no studies have investigated this association among primary care recipients with hypertension.

METHODS

We examined the anonymized records of all public general outpatient visits by patients aged 45+ during January 2007-December 2010 in Hong Kong to extract primary care patients with hypertension for analysis. We took the last consultation date as the baseline and followed them up for 4 years (until 2011-2014) to observe any subsequent acute hospitalization due to stroke. Mixed-effects Cox models (random intercept across 74 included clinics) were implemented to examine the association between depression (ICPC diagnosis or anti-depressant prescription) at baseline and the hazard of acute stroke (ICD-9: 430-437.9). Effect modification by age, sex, and recipient status of social security assistance was examined in extended models with respective interaction terms specified.

RESULTS

In total, 396 858 eligible patients were included, with 9099 (2.3%) having depression, and 10 851 (2.7%) eventually hospitalized for stroke. From the adjusted analysis, baseline depression was associated with a 17% increased hazard of acute stroke hospitalization [95% confidence interval (CI) 1.03-1.32]. This association was suggested to be even stronger among men than among women (hazard ratio = 1.29, 95% CI 1.00-1.67).

CONCLUSION

Depression is more strongly associated with acute stroke incidence among male than female primary care patients with hypertension. More integrated services are warranted to address their needs.

Influence of altitude on hypertension phenotypes and responses to antihypertensive therapy: Review of the literature and design of the INTERVENCION trial

Systemic arterial hypertension constitutes the leading cause of mortality worldwide, and affects people living at different altitudes above sea level (AASL). AASL has a major impact on cardiovascular function and various biologic pathways that regulate blood pressure-related phenotypes, but whether it affects the clinical response to antihypertensive therapy is unknown. The hemodynamic adaptations observed among lowlanders acutely exposed to high altitude (HA) is distinct from those observed among HA dwellers. However, the phenotypic patterns of hypertension and the response to standard antihypertensive agents among adults chronically exposed to different AASL are poorly understood. The authors describe the protocol for the INTERVENCION trial, a randomized clinical trial designed to assess the effects of three first-line antihypertensive monotherapies (a thiazide diuretic, an angiotensin receptor blocker, and a calcium channel blocker) on peripheral and central blood pressure, in-office blood pressure, and ambulatory blood pressure hemodynamics of hypertensive patients living at different AASL (low altitude, intermediate altitude, and high altitude). The primary end point is the reduction in 24-hour brachial systolic blood pressure. The INTERVENCION trial will provide the first clinical trial data regarding the influence of AASL on the response to antihypertensive monotherapy, as well as the hemodynamic characteristics of arterial hypertension at different AASL.

Carotid Intima-Media Thickness and Circulation Markers of Inflammation in Patients With Depression

Objective:

Growing evidence indicates that depressive disorders (DDs) are an important risk factor for atherosclerosis. The aim of this study was to evaluate the presence of common carotid artery (CCA) intima-media thickness (IMT) and circulation inflammation markers in patients with DD.

Methods:

A cross-sectional prospective study was undertaken comparing 40 patients with DD to 40 individuals free of depression, matched for age and gender. The Beck Depression Inventory questionnaire, serum total cholesterol, triglycerides, high-sensitivity C-reactive protein, interleukin-6, tumor necrosis factor α, P-selectin, and E-selectin levels were measured. The CCA-IMT was assessed with duplex sonography.

Results:

Patients with DD were more likely to smoke (65% vs 40%; P = .03) and have higher levels of serum total cholesterol (211 mg/dL vs 181 mg/dL; P = .010), triglycerides (138 mg/dL vs 97 mg/dL; P = .005), and P-selectin (0.87 ng/mL vs 0.61 ng/mL; P = .05) and lower levels of interleukin 6 (4.4 ± 2.1 pg/mL vs 10.3 ± 1.1 pg/mL; P = .002). The CCA-IMT was similar in both groups (0.07 ± 0.02 cm vs 0.06 ± 0.01 cm; P = .31). Among those with CCA-IMT in the upper quartile, subjects in the DD group had lower levels of interleukin 6 ( P = .05) and triglycerides ( P = .01) and higher levels of soluble P-selectin ( P = .03).

Conclusion:

Patients with DD do not present with higher CCA-IMT than a control group, although smoking and a higher level of serum lipids are present. Inflammatory biomarkers seem to be higher in patients with DD.

Associations of depression-anxiety and dyslipidaemia with subclinical carotid arterial disease: Findings from the Whitehall II Study

AIMS

There is mixed evidence for an association between depression and/or anxiety and carotid intima-media thickness, and limited information on the related role of dyslipidaemia. Here we report associations between depression and/or anxiety and intima-media thickness in the Whitehall II cohort, considering the moderating effects of sex and dyslipidaemia.

METHODS

A total of 2822 men and 1112 women (61 ± 6 years) were studied during phase 7 (2002-2004) of the Whitehall II study. Intima-media thickness and lipid levels were assessed, and questionnaires (general health questionnaire and the Centre for Epidemiologic Studies depression scale) were completed. Linear regression was used to explore relationships between depression and/or anxiety and intima-media thickness and the moderating effects of sex and dyslipidaemia.

RESULTS

A total of 1461 participants were categorised with depression and/or anxiety. The association between depression and/or anxiety and intima-media thickness differed between men and women so analyses were undertaken separately by sex. In men, intima-media thickness was significantly associated with dyslipidaemia (P = 0.002) but not depression and/or anxiety (P = 0.29). In women, both dyslipidaemia and depression and/or anxiety were independently associated with intima-media thickness (P = 0.028 and P = 0.031). The greatest intima-media thickness was in women with both depression and/or anxiety and dyslipidaemia. These results were replicated when the general health questionnaire score was substituted for depression and/or anxiety and non-high-density lipoprotein cholesterol for dyslipidaemia.

CONCLUSIONS

Depression and/or anxiety is associated with increased intima-media thickness in women but not in men. Dyslipidaemia is associated with intima-media thickness in both men and women. Women with both depression and/or anxiety and dyslipidaemia are potentially at the greatest risk of cardiovascular disease.

The effect of treatment response on endothelial function and arterial stiffness in depression. A prospective study

BACKGROUND

Major depression is associated with endothelial dysfunction and arterial stiffening, which may mediate development of hypertension and increased cardiovascular risk. The effect of response to antidepressant treatment on these vascular parameters has not been elucidated.

AIMS

We aimed to assess the net effect of antidepressant therapy on endothelial function and arterial stiffness in patients with psychotic depression.

METHOD

Thirty-seven patients with major psychotic depression, according to DSM-IV-TR, were treated with titrated citalopram 20-60 mg and risperidone 0.5-1 mg and were followed for 6 months. Twelve additional patients who denied treatment, or were non-compliant, were also followed for the same time period. Vascular function was assessed by flow-mediated dilatation (FMD), carotid-femoral pulse wave velocity (PWV) and augmentation index (AI), at baseline and at the end of follow-up.

RESULTS

Aortic and peripheral blood pressure (BP), PWV, FMD and AI (p < 0.05 for all) were significantly improved in the group that received treatment. Overall, only responders to treatment (n = 24) presented significant improvements in all hemodynamic and vascular parameters (p < 0.05 for all), irrespectively of traditional cardiovascular risk factors (TRFs), vasoactive medication and BP lowering. In a secondary analysis, patients with psychotic depression presented worse endothelial function as compared to controls matched for TRFs.

LIMITATIONS

Non-randomized study.

CONCLUSIONS

Patients who respond to therapy for major psychotic depression present sustained improvement in vascular function. Given that depressed patients are considered to be at high cardiovascular risk and are often non-compliant with treatment, further research to assess cardiovascular benefits of vigilant monitoring of antidepressant therapy is warranted.

Impact of Cardiovascular Risk Factors on Carotid Intima-Media Thickness and Degree of Severity: A Cross-Sectional Study

Objective

Age, hypertension, dyslipidemia and diabetes are common cardiovascular risk factors (CVRFs) that contribute to the development of atherosclerosis in cardiovascular system including carotid artery disease. However, the impact of these risk factors on the increased carotid intima-media thickness (cIMT) and degree of carotid severity remains to be further clarified. This study aims to evaluate the relationship between CVRFs and degree of carotid severity and cIMT in high-risk subjects.

Methods

Four thousand and three hundred ninety-four subjects with one or more risk factors were retrospectively reviewed in this study. Patients were divided into different groups based on age, the type and quantity of CVRFs. cIMT and degree of carotid artery stenosis were measured and analyzed based on carotid ultrasound imaging with findings compared to the CVRFs to determine the correlation between these variables.

Results

Aging was significantly associated with degree of severity (P < 0.05) and cIMT was significantly increased with age (P < 0.05). Individual CVRF analysis shows that hypertension was more related to the degree of severity than dyslipidemia and diabetes with corresponding abnormal cIMT rates being 79.39%, 72.98% and 32.37%, respectively. The prevalence of carotid atherosclerosis were 20.06%, 22.88% and 28.63%, respectively corresponding to patients with zero, one and more than one chronic diseases. The percentage of abnormal cIMT in hypertensive patient group with dyslipidemia is significantly higher than the other groups (P< 0.05).

Conclusions

This study shows a direct correlation between the degree of carotid severity and cIMT and cardiovascular risk factors, especially with age and hypertension. Carotid atherosclerosis is closely related to the number of cardiovascular risk factors.

Anxiety and depressive symptoms are associated with higher carotid intima-media thickness. Cross-sectional analysis from ELSA-Brasil baseline data

BACKGROUND

Studies focusing on the association between anxiety/depressive symptoms and accelerated subclinical atherosclerosis have yielded mixed results. Our aim is to examine associations between anxiety/depressive symptoms, common mental disorder (CMD), major depression disorder (MDD) or generalized anxiety disorder (GAD) and carotid intima-media thickness (CIMT) in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) cohort baseline.

METHODS

The ELSA-Brasil baseline assessment included CIMT measurements and the Clinical Interview Schedule - Revised (CIS-R), a validated questionnaire for anxiety/depressive symptoms/diagnoses. We analyzed participants without previous coronary heart disease or stroke, and with high-quality CIMT images. We built regression models to determine whether the CIS-R score, CMD, MDD or GAD were associated with maximal CIMT levels.

RESULTS

The study sample comprised 9744 participants. We found that individuals with higher CIS-R scores (Odds ratio for one standard deviation increase [OR]:1.12; 95% confidence interval [95%CI]:1.06-1.19), CMD (OR:1.22; 95%CI:1.07-1.38) and GAD (OR:1.19; 95%CI:1.01-1.41) had significantly higher odds of being classified in the highest age, sex and race-specific CIMT quartile. In the linear models, after adjustment for traditional cardiovascular risk factors, higher CIS-R scores (β:0.005; P = 0.010) and GAD (β:0.010; P = 0.049) were independently associated with CIMT values.

CONCLUSION

Individuals with more symptoms of anxiety and/or depression, or diagnoses of CMD or GAD, had higher CIMT values, compared to peers of same age, sex and race. CIS-R scores and GAD were independently associated with higher CIMT values. These results suggest an association between anxiety/depressive symptoms (and, most notably, GAD) and accelerated subclinical atherosclerosis.
