Evaluation of Splenic Metabolic Activity With 18FDG-PET in Hypertension

Neuromed IRCCS

Status: Unknown

Conditions: Hypertension

Treatments: Other: PET/CT scan

Study type: Observational

Funder types: Other

Identifiers

NCT02572765

LMB05

Details and patient eligibility

About

The purpose of this study is to evaluate the splenic activation in hypertensive patients, as compared to normotensives, using FDG-PET/CT imaging. Moreover, the investigators will investigate whether the splenic metabolic activity relates to the expression of circulating inflammatory proteins (high-sensitivity C-reactive protein [hsCRP]), interleukin-1b (IL-1b), tumor necrosis factor-a (TNF-a) or to immune profiles of activated T cells.

Enrollment: 120 estimated patients

Sex: All

Ages: 30 to 85 years old

Volunteers: Accepts Healthy Volunteers

• absence of acute or chronic inflammatory or autoimmune disease
• diagnosis of presence/absence of hypertension, on the basis of documented medical history

Exclusion criteria
