Background: Psoriasis is associated with a heightened risk of cardiovascular disease and higher prevalence of metabolic syndrome.

Objective: Investigate the effect of metabolic syndrome and its factors on early coronary artery disease assessed as noncalcified coronary burden by coronary computed tomography angiography in psoriasis.

Methods: This cross-sectional study consisted of 260 participants with psoriasis and coronary computed tomography angiography characterization. Metabolic syndrome was defined according to the harmonized International Diabetes Federation criteria.

Results: Of the 260 participants, 80 had metabolic syndrome (31%). The metabolic syndrome group had a higher burden of cardiometabolic disease, systemic inflammation, noncalcified coronary burden, and high-risk coronary plaque. After adjusting for Framingham risk score, lipid-lowering therapy, and biologic use, metabolic syndrome (β = .31; P < .001) and its individual factors of waist circumference (β = .33; P < .001), triglyceride levels (β = .17; P = .005), blood pressure (β = .18; P = .005), and fasting glucose (β = .17; P = .009) were significantly associated with noncalcified coronary burden. After adjusting for all other metabolic syndrome factors, blood pressure and waist circumference remained significantly associated with noncalcified coronary burden.

Limitations: Observational nature with limited ability to control for confounders.

Conclusions: In psoriasis, individuals with metabolic syndrome had more cardiovascular disease risk factors, systemic inflammation, and noncalcified coronary burden. Efforts to increase metabolic syndrome awareness in psoriasis should be undertaken to reduce the heightened cardiovascular disease risk.

Association Among Noncalcified Coronary Burden, Fractional Flow Reserve, and Myocardial Injury in Psoriasis.

J Am Heart Assoc 2020 11 10;9(22):e017417. Epub 2020 Nov 10.

National Heart, Lung, and Blood Institute National Institutes of Health Bethesda MD.

Background Myocardial infarction and premature death have been observed in patients with psoriasis. Although inflammation-driven accelerated atherosclerosis has been proposed as a mechanism, the relationship between subclinical noncalcified coronary burden (NCB), functional coronary flow impairment, and myocardial injury is unclear. Methods and Results In an ongoing longitudinal cohort study, 202 consecutive patients with psoriasis (168 at 1 year) underwent coronary computed tomography angiography to identify coronary plaque, quantify NCB, and calculate coronary fractional flow reserve by computed tomography. Serum high-sensitivity troponin-T (hs-cTn-T) was measured using a fifth-generation assay. Overall, patients were middle-aged, predominantly male, and low cardiovascular risk. A higher than median NCB associated with a positive hs-cTn-T (fully adjusted model [odds ratio (OR), 1.72; 95% CI, 1.10-2.69, =0.018]) at baseline. Additionally, patients with a higher than median baseline NCB had higher odds of positive hs-cTn-T at 1 year in fully adjusted analyses (adjusted OR, 2.36; 95% CI, 1.47-3.79, <0.001). Higher NCB was associated with a higher frequency of fractional flow reserve by computed tomography ≤0.80 (36.11% versus 25.11%, Pearson χ=6.84, =0.009, unadjusted OR, 2.09; 95% CI, 1.36-3.22, <0.001) and higher frequency of a positive hs-cTn-T (54.36% versus 27.54%, Pearson χ=32.23, <0.001) in adjusted models (OR, 2.63; 95% CI, 1.56-4.42, <0.001). Conclusions NCB was associated with hs-cTn-T at baseline as well as at 1 year. Furthermore, patients with high NCB had higher prevalence of fractional flow reserve by computed tomography ≤0.80 and a >2- fold higher odds of positive hs-cTn-T. These findings underscore the importance of early vascular disease in driving myocardial injury, and support conduct of myocardial perfusion studies to better understand these findings.

Chronic inflammation in psoriasis promotes visceral adiposity associated with noncalcified coronary burden over time.

JCI Insight 2020 11 19;5(22). Epub 2020 Nov 19.

National Heart, Lung, and Blood Institute, Bethesda, Maryland, USA.

BACKGROUNDPsoriasis is a chronic inflammatory skin disease associated with increased obesity, noncalcified coronary artery burden (NCB), and incident myocardial infarction. Here, we sought to assess the relationship among inflammation, visceral adipose tissue (VAT), and NCB. Furthermore, we evaluated whether improvement in VAT would be associated with reduction in NCB over time in psoriasis.METHODSConsecutive psoriasis patients underwent coronary CT angiography to quantify NCB and abdominal CT to calculate VAT at baseline (n = 237), 1 year (n = 176), and 4 years (n = 50).RESULTSPatients with high levels of high-sensitivity C-reactive protein (hs-CRP) had significantly greater visceral adiposity (17,952.9 ± 849.2 cc3 vs. 13370.7 ± 806.8 cc3, P < 0.001) and noncalcified coronary burden (1.26 ± 0.03 vs. 1.07 ± 0.02 mm2) than those with low levels of hs-CRP. Those with higher levels of VAT had more systemic inflammation (hs-CRP, median [IQR], 2.5 mg/L [1.0-5.3 mg/L] vs. 1.2 mg/L [0.6-2.9 mg/L]), with approximately 50% higher NCB (1.42 ± 0.6 mm2 vs. 0.91 ± 0.2 mm2, P < 0.001). VAT associated with NCB in fully adjusted models (β = 0.47, P < 0.001). At 1-year follow-up, patients who had worsening hs-CRP had an increase in VAT (14,748.7 ± 878.1 cc3 to 15,158.7 ± 881.5 cc3; P = 0.03), whereas those who had improved hs-CRP improved their VAT (16,876.1 ± 915.2 cc3 to 16310.4 ± 889.6 cc3; P = 0.04). At 1 year, there was 10.3% reduction in NCB in those who had decreased VAT (β = 0.26, P < 0.0001), which persisted in a subset of patients at 4 years (β = 0.39, P = 0.003).CONCLUSIONSInflammation drives development of VAT, increased cardiometabolic risk, and NCB in psoriasis. Reduction of inflammation associated with reduction in VAT and associated with longitudinal improvement in NCB. These findings demonstrate the important role of inflammation in the development of VAT in humans and its effect on early atherogenesis.TRIAL REGISTRATIONClinicalTrials.gov NCT01778569.FUNDINGThis study was supported by the National Heart, Lung, and Blood Institute Intramural Research Program (HL006193-05), the NIH Medical Research Scholars Program, a public-private partnership supported jointly by the NIH and contributions to the Foundation for the NIH from the Doris Duke Charitable Foundation (no. 2014194), the American Association for Dental Research, the Colgate-Palmolive Company, Genentech, and Elsevier as well as private donors.

Relationship between chronic stress-related neural activity, physiological dysregulation and coronary artery disease in psoriasis: Findings from a longitudinal observational cohort study.

Atherosclerosis 2020 10 29;310:37-44. Epub 2020 Jul 29.

Background And Aims: Amygdalar 18F-fluorodeoxyglucose (FDG) uptake represents chronic stress-related neural activity and associates with coronary artery disease by coronary computed tomography angiography (CCTA). Allostatic load score is a multidimensional measure related to chronic physiological stress which incorporates cardiovascular, metabolic and inflammatory indices. To better understand the relationship between chronic stress-related neural activity, physiological dysregulation and coronary artery disease, we studied the association between amygdalar FDG uptake, allostatic load score and subclinical non-calcified coronary artery burden (NCB) in psoriasis.

Methods: Consecutive psoriasis patients (n = 275 at baseline and n = 205 at one-year follow-up) underwent CCTA for assessment of NCB (QAngio, Medis). Amygdalar FDG uptake and allostatic load score were determined using established methods.

Results: Psoriasis patients were middle-aged, predominantly male and white, with low cardiovascular risk by Framingham risk score and moderate-severe psoriasis severity. Allostatic load score associated with psoriasis severity (β = 0.17, p = 0.01), GlycA (a systemic marker of inflammation, β = 0.49, p < 0.001), amygdalar activity (β = 0.30, p < 0.001), and NCB (β = 0.39; p < 0.001). Moreover, NCB associated with amygdalar activity in participants with high allostatic load score (β = 0.27; p < 0.001) but not in those with low allostatic load score (β = 0.07; p = 0.34). Finally, in patients with an improvement in allostatic load score at one year, there was an 8% reduction in amygdalar FDG uptake (p < 0.001) and a 6% reduction in NCB (p = 0.02).

Conclusions: In psoriasis, allostatic load score represents physiological dysregulation and may capture pathways by which chronic stress-related neural activity associates with coronary artery disease, emphasizing the need to further study stress-induced physiological dysregulation in inflammatory disease states.

Chronic inflammation, cardiometabolic diseases and effects of treatment: Psoriasis as a human model.

Trends Cardiovasc Med 2020 11 20;30(8):472-478. Epub 2019 Nov 20.

Chronic inflammation in humans is associated with accelerated development of cardiometabolic diseases such as myocardial infarction, stroke, and diabetes. Strong evidence from animal models and human interventional trials including CANTOS (The Canakinumab Anti-inflammatory Thrombosis Outcome Study) suggests that targeting residual systemic inflammation in humans may impart a benefit in reducing cardiometabolic diseases. Diseases associated with heightened immune-activation and systemic inflammation including psoriasis, rheumatoid arthritis, systemic lupus erythematosus, and human immunodeficiency virus infection are associated with upwards of two to seven-fold risk of future adverse cardiac events even when adjusted for traditional risk factors. Over the past decade, psoriasis has been utilized as a human model to study inflammatory-induced cardiometabolic dysfunction and to better understand residual risk due to inflammation. The high prevalence and early onset of cardiovascular disease in psoriasis enhances the likelihood of discovering novel pathways in vascular disease progression when followed over time. Furthermore, the United States Food and Drug Administration approved treatments for psoriasis include cytokine inhibitors (anti-tumor necrosis factor, anti-interleukin 17, anti-interleukin 12/23) which while treating the skin disease provide a unique opportunity to characterize how treating the inflammatory pathways may impact atherosclerosis. Herein, we provide a review of chronic inflammation, cardiometabolic disease associations, and treatment effects with a focus on psoriasis as a human model of study.

Association Between Soluble Lectinlike Oxidized Low-Density Lipoprotein Receptor-1 and Coronary Artery Disease in Psoriasis.

JAMA Dermatol 2020 02;156(2):151-157

National Institute of Arthritis and Musculoskeletal and Skin Diseases, National Institutes of Health, Bethesda, Maryland.

Importance: Psoriasis, a chronic inflammatory skin disease associated with accelerated noncalcified coronary burden (NCB) by coronary computed tomography angiography (CCTA), accelerates lipoprotein oxidation in the form of oxidized modified lipoproteins. A transmembrane scavenger receptor for these oxidized modified lipoproteins is lectinlike oxidized low-density lipoprotein receptor-1 (LOX-1), which has been reported to be associated with coronary artery disease. It is unknown whether this receptor is associated with coronary artery disease in psoriasis.

Objective: To assess the association between soluble LOX-1 (sLOX-1) and NCB in psoriasis over time.

Design, Setting, And Participants: In a cohort study at the National Institutes of Health, 175 consecutive patients with psoriasis were referred from outpatient dermatology practices between January 1, 2013, and October 1, 2017. A total of 138 consecutively recruited patients with psoriasis were followed up at 1 year.

Exposures: Circulating soluble lectinlike oxidized low-density lipoprotein receptor-1 levels were measured blindly by field scientists running undiluted serum using an enzyme-linked immunosorbent assay.

Main Outcomes And Measures: Coronary computed tomography angiography scans were performed to quantify NCB in all 3 major epicardial coronary arteries by a reader blinded to patient demographics, visit, and treatment status.

Results: Among the 175 patients with psoriasis, the mean (SD) age was 49.7 (12.6) years and 91 were men (55%). The cohort had relatively low median cardiovascular risk by Framingham risk score (median, 2.0 [interquartile range (IQR), 1.0-6.0]) and had a mean (SD) body mass index (calculated as weight in kilograms divided by height in meters squared) suggestive of overweight profiles (29.6 [6.0]). Elevated sLOX-1 levels were found in patients with psoriasis compared with age- and sex-matched controls (median, 210.3 [IQR, 110.9-336.2] vs 83.7 [IQR, 40.1-151.0]; P < .001), and were associated with Psoriasis Area Severity Index (PASI) score (β = 0.23; 95% CI, 0.082-0.374; P = .003). Moreover, sLOX-1 was associated with NCB independent of hyperlipidemia status (β = 0.11; 95% CI, 0.016-0.200; P = .023), an association which persisted after adjusting for traditional cardiovascular risk factors, statin use, and biologic psoriasis treatment (β = 0.10; 95% CI, 0.014-0.193; P = .03). At 1 year, in those who had clinical improvement in PASI (eg, >50% improvement), a reduction in sLOX-1 (median, 311.1 [IQR, 160.0-648.8] vs median, 224.2 [IQR, 149.1 - 427.4]; P = .01) was associated with a reduction in NCB (β = 0.14; 95% CI, 0.028-0.246; P = .02).

Conclusions And Relevance: Soluble lectinlike oxidized low-density lipoprotein receptor-1 levels were elevated in patients with psoriasis and were associated with severity of skin disease. Moreover, sLOX-1 associated with NCB independent of hyperlipidemia status, suggesting that inflammatory sLOX-1 induction may modulate lipid-rich NCB in psoriasis. Improvement of skin disease was associated with a reduction of sLOX-1 at 1 year, demonstrating the potential role of sLOX-1 in inflammatory atherogenesis in psoriasis.

Improving CNS Delivery to Brain Metastases by Blood-Tumor Barrier Disruption.

Trends Cancer 2019 08 20;5(8):495-505. Epub 2019 Jul 20.

Department of Pharmaceutical Sciences, School of Pharmacy, West Virginia University HSC, Morgantown, West Virginia 26506, USA. Electronic address:

Brain metastases encompass nearly 80% of all intracranial tumors. A late stage diagnosis confers a poor prognosis, with patients typically surviving less than 2 years. Poor survival can be equated to limited effective treatment modalities. One reason for the failure rates is the presence of the blood-brain barrier (BBB) and blood-tumor barrier (BTB) that limit the access of potentially effective chemotherapeutics to metastatic lesions. Strategies to overcome these barriers include new small molecule entities capable of crossing into the brain parenchyma, novel formulations of existing chemotherapies, and disruptive techniques. Here, we review BBB physiology and BTB pathophysiology. Additionally, we review the limitations of routinely practiced therapies and three current methods being explored for BBB/BTB disruption for improved delivery of chemotherapy to brain tumors.

Feeding soy protein isolate and n-3 PUFA affects polycystic liver disease progression in a PCK rat model of autosomal polycystic kidney disease.

J Pediatr Gastroenterol Nutr 2015 Apr;60(4):467-73

*Division of Animal and Nutritional Sciences †Division of Plant and Soil Sciences ‡Department of Chemistry, West Virginia University, Morgantown §United Hospital, Bridgeport, WV.

Objective: In polycystic liver disease (PCLD), multiple cysts cause liver enlargement, structural damage, and loss of function. Soy protein and dietary ω-3 polyunsaturated fatty acids (n-3 PUFAs) have been found to decrease cyst proliferation and inflammation in polycystic kidney disease. Therefore, the aim of the study was to investigate whether soy protein and n-3 PUFA supplementation attenuates PCLD.

Methods: Young (age 28 days) female PCK rats were fed (n = 12 per group) either casein + corn oil (casein + CO), casein + soybean oil (casein + SO), soy protein isolate + soybean oil (SPI + SO), or SPI + 1:1 soybean/salmon oil blend (SPI + SB) diet for 12 weeks. Liver histology, gene expression by real-time quantitative polymerase chain reaction, and serum markers of liver injury were determined.

Results: Diet had no effect on PCLD progression as indicated by no significant differences in liver weight and hepatic proliferation gene expression between diet groups. PCK rats fed SPI + SB diet, however, had the greatest (P < 0.05) histological evidence of hepatic cyst obstruction, portal inflammation, steatosis, and upregulation (P = 0.03) of fibrosis-related genes. Rats fed SPI + SB diet also had the lowest (P < 0.001) serum cholesterol and higher (P < 0.05) serum alkaline phosphatase and bilirubin concentrations.

Conclusions: Feeding young female PCK rats SPI and n-3 PUFA failed to attenuate PCLD progression. Furthermore, feeding SPI + SB diet resulted in complications of hepatic steatosis attributable to cysts obstruction of bile duct and hepatic vein. Based on the results, it was concluded that diet intervention alone was not effective at attenuating PCLD associated with autosomal recessive polycystic kidney disease.
