Positron Emission Tomography (PET) Imaging of Neuroinflammation in Patients With Neurological Dysfunction After Severe Acute Respiratory Syndrome Coronavirus 2 (SARS CoV 2) Infection
PET Imaging of Neuroinflammation in Patients With Neurological Dysfunction After SARS-CoV-2 Infection
Sponsor
University of Alabama at Birmingham
Enrollment
60 participants
Start Date
Nov 10, 2023
Study Type
INTERVENTIONAL
Conditions
Summary
This clinical imaging study will use the small molecule translocator protein (TSPO) ligand, Fluorodeoxyglucose(18F)-labeled DPA-714, to visualize and quantify neuroinflammation in individuals with post-acute sequelae of SARS-CoV-2 (PASC) . The brain uptake of DPA-714 will be contrasted with healthy subjects.
Eligibility
Min Age: 18 YearsMax Age: 65 Years
Inclusion Criteria5
- 18 to 65 years of age
- Healthy volunteer OR Clinical diagnosis of post-acute sequelae of SARS-CoV-2 (PASC)
- High or mixed affinity binder for TSPO ligands based on genotyping for single nucleotide polymorphism (SNP) rs6971.
- PASC participants must have been previously infected with SARS-CoV-2. Their neurological symptoms must have been present for at least four weeks prior to the enrollment.
- Healthy control participants must have no neurological symptoms
Exclusion Criteria13
- Contraindication to MRI
- Pregnancy
- Lactation

Fasting glucose > 100 mg/dL, 25. Blood chemistry results indicating organ damage or other serious medical condition 26. Use of illicit substances within the past 6 months 27. Self-reported diagnosis of Type I or Type II diabetes 28. Healthy controls must not regularly take over-the-counter anti-inflammatory medication, analgesics (except aspirin), or sleep medication
