No Intervention: Chart Review (not actively recruiting)
Chart review of previously consented participants from the entire NIH RECOVER cohort, comprised of 15,000 infected and 2,600 noninfected patients across the country.

|
Experimental: COVID infected and healthy controls
Participants will perform a needle fat biopsy for tissue harvesting in the subacute phase (15-30d) of Covid-19 infection or as a healthy control. Our goal is 20 COVID-19 infected participants and 10 healthy controls.
|
Procedure: Adipose Tissue Biopsy
After an overnight fast, approximately 1-2 grams of subcutaneous fat will be removed by a needle. Participants will have a local anesthetic prior to the procedure. The needle fat biopsy will be repeated at quarterly intervals for one year (every 3 months). We will also draw 1 10mL tube of blood at each biopsy for measurement of inflammatory cytokines. |
Experimental: Healthy Controls Only
We are looking for 20 healthy controls for 2 in-person visits on separate days.

Procedure: Adipose Tissue Biopsy
After an overnight fast, approximately 1-2 grams of subcutaneous fat will be removed by a needle. Participants will have a local anesthetic prior to the procedure. The needle fat biopsy will be repeated at quarterly intervals for one year (every 3 months). We will also draw 1 10mL tube of blood at each biopsy for measurement of inflammatory cytokines. Diagnostic Test: Steady State Plasma Glucose (SSPG) Test An Insulin Sensitivity Test (SSPG: Steady State Plasma Glucose) is performed to determine if participants are insulin sensitive or insulin resistant. This test is approximately 5-6 hours in length. Participants will be asked to fast for 12 hours. The insulin sensitivity test is designed to measure how well your cells remove glucose from your blood in response to insulin. During this test participants will have two small catheters (tubing) placed in their veins (I.V. lines). The total amount of blood that will be drawn during this test will be 140 mL of blood (approximately 9.5 tablespoons). Insulin is a natural hormone, and octreotide (a synthetic hormone) is a drug that temporarily blocks the secretion of insulin from your pancreas. A member of the research team is present and monitoring the results along with the nursing staff.
Other Name: Insulin Sensitivity Test |
- Triglyceride/HDL-cholesterol ratio [ Time Frame: 2 years ]Investigate the relationship between insulin resistance, as described by triglyceride/HDL-cholesterol ratio, and incident PASC (long COVID).
- Concentration of Viral RNA in Adipose Tissue [ Time Frame: 2 years ]Investigate the expression of viral RNA in adipose tissue in response to COVID-19 infection. Compare adipose tissue transcripts such as known MODY transcription factors measured by PCR between COVID-19 infected participants and healthy controls.
- Rate of Inflammatory Response [ Time Frame: 2 years ]Investigate inflammatory response to PPARgamma agonist (drug) and other compounds tested in vitro in human fat cells. Compare plasma inflammatory cytokine levels in serum samples as measured by Luminex immunoassay between participants identified as Insulin Sensitive (IS) and Insulin Resistant (IR) using the 2-stage Steady State Plasma Glucose test.
- Rate of Inflammatory Gene Expression in Adipose Tissue [ Time Frame: 2 years ]Investigate the expression of inflammatory genes in adipose tissue in response to COVID-19 infection. Compare adipose tissue transcripts such as defensin chemokine receptors and platelet activation factors measured by PCR between COVID-19 infected participants and healthy controls.
