BACKGROUND: Psoriasis is associated with cardiovascular disease; it has been proposed that increased cardiovascular risk is caused by low-grade systemic inflammation involving organs and tissues other than the skin and joints. OBJECTIVES: To investigate signs of vascular inflammation in untreated patients with moderate-to-severe psoriasis assessed by (18) F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography. A secondary objective was to assess signs of subcutaneous adipose tissue inflammation...

BACKGROUND AND AIMS: Psoriasis is a chronic inflammatory disorder associated with vascular inflammation, measured by 18-fluorodeoxyglucose positron emission tomography/computed tomography (18-FDG PET/CT), and an increased risk of myocardial infarction. Patients with psoriasis are also more likely to suffer from comorbid depression. Whether depression accelerates the development of subclinical atherosclerosis in psoriasis is unknown. METHODS: Patients were selected from within a larger psoriasis cohort...

OBJECTIVE: To understand whether directly measured psoriasis severity is associated with vascular inflammation assessed by (18)F-fluorodeoxyglucose positron emission tomography computed tomography. APPROACH: In-depth cardiovascular and metabolic phenotyping was performed in adult psoriasis patients (n=60) and controls (n=20). Psoriasis severity was measured using psoriasis area severity index. Vascular inflammation was measured using average aortic target-to-background ratio using (18)F-fluorodeoxyglucose positron emission tomography computed tomography...

Nuclear medicine techniques have been an integral part of infection and inflammation imaging for decades; in recent years, fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) has taken over many indications. This review provides a comprehensive overview of the current and potential applications for FDG-PET/CT in infectious and inflammatory diseases (ie, systemic infections, bone infections, vascular infection and inflammation, thoracic and abdominal inflammation) and potential novel applications in both infection and inflammation...

Severe psoriasis is a systemic inflammatory disease involving major arteries and internal organs. The association between psoriasis and arterial inflammation, however, has been noted mostly in patients with moderate to severe psoriasis. Therefore, it is still not clear whether mild psoriasis also increases the arterial inflammation and cardiovascular disease. In this study, we aimed to investigate systemic inflammation using (18) F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in patients with mild psoriasis...

INTRODUCTION: Psoriasis and psoriatic arthritis (PsA) increase cardiovascular disease (CVD) risk, but surrogate markers for CVD in these disorders are inadequate. Because the presence of sacroiliitis may portend more severe PsA, we hypothesized that sacroiliitis defined by computed tomography (CT) would be associated with increased vascular inflammation defined by 18-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT), which is an established measure of CVD...

OBJECTIVE: Psoriasis (PSO) and rheumatoid arthritis (RA) increase cardiovascular diseases (CVD) beyond traditional risk factors. Vascular inflammation has previously been demonstrated to be present in PSO and RA using [18F]-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) imaging. However, vascular inflammation has not been compared in these two disorders relative to a healthy reference population. Thus, vascular inflammation was quantitatively assessed in patients with PSO (n=10), RA (n=5), and healthy subjects (n=10) using FDG-PET/CT...

Psoriasis is a model Th1-mediated inflammatory disease associated with increased incidence of stroke and cardiovascular disease (CVD). The mechanism behind these associations is unknown, however abnormal HDL particle composition measured by nuclear magnetic resonance (NMR) spectroscopy has been shown to be associated with CVD. Using [18F]-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT), a validated surrogate marker of CVD, we assessed whether HDL particle size and concentration were associated with vascular inflammation in patients with psoriasis...

OBJECTIVE: To evaluate the feasibility of using [18F]-fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET/CT) to detect and quantify systemic inflammation in patients with psoriasis. DESIGN: Case series with a nested case-control study. SETTING: Referral dermatology and preventive cardiology practices. PARTICIPANTS: Six patients with psoriasis affecting more than 10% of their body surface area and 4 controls age and sex matched to 4 of the patients with psoriasis for a nested case-control study...
