简要总结
Background:
SARS-CoV-2 is the virus that causes COVID-19. Some people who recover from COVID-19 have symptoms that last long after the active infection ends. This is called "long COVID." Sometimes, long COVID can affect the nerves and cause problems with sleep, thinking, the senses, and movement. Researchers want to find out whether people with long COVID have retained inactive remnants of SARS-CoV-2 in their bodies.
Objective:
To collect tissue samples to see if people with long COVID have remnants of SARS-CoV-2 in their bodies.
Eligibility:
People 18 years or older who have recovered from COVID-19, both with and without neurologic symptoms.
Design:
Participants will have 2 to 6 inpatient or outpatient visits over 4 months. Each visit will last 4 to 5 days.
Participants will be screened to make sure it is safe to collect tissue samples from their body. They will have a physical and dental exam. They will have imaging scans and a test of their heart function. They will complete questionnaires about their health. They will give blood, urine, saliva, and stool samples. Their sense of taste and smell will be tested.
Tissue samples will be taken from the digestive tract, lungs, colon, skin, muscle, lymph nodes, nasal passages, and mouth. Participants may be numbed or sedated for some of the procedures.
Swabs will be used to collect cells from inside the mouth and nose.
Participants will undergo lumbar puncture. A thin needle will be inserted into their lower back to draw out a sample of the fluid around their spinal cord.
Participants will have follow-up phone calls after each clinic visit.
详细描述
Study Description:
It has been demonstrated that remnants of the SARS-CoV-2 virus remain after the resolution of the acute infective period. It is not known if these viral remnants interact with host tissues in the development and maintenance of the Post-Acute Sequelae of COVID-19 (PASC)/Long COVID. Better understanding of how to recover and characterize SARS-CoV-2 viral remnants from humans is a valuable first step in understanding the health impact that they may have on humans. This study will focus on the recovery and characterization of SARS-CoV-2 remnants from multiple organ sites of individual volunteers with persistent neurological complications from SARS-CoV-2 (Neuro-PASC) and volunteers those who have recovered from a SARS-CoV-2 infection (RV).
Objectives:
- Primary Objective:
--To determine where remnants of SARS-CoV-2 virus can be recovered in persons with neuro-PASC and RVs.

入选标准
- •INCLUSION CRITERIA:
- •Recovered Volunteers (RV): Six healthy persons who have recovered from an acute SARS-CoV-2 infection.
- •Inclusion criteria:
- •Participants 18 and older
- •Ability to provide informed consent
- •Completed participation in Phase B of Protocol 000089
- •Met 000089 Inclusion criteria for Mild to Moderate COVID-19 without PASC symptoms:
- •Licensed Independent Practitioner documentation of a stable state of general well-health and physical function prior to contracting SARS-CoV-
- •This may include medical records, correspondence letters, or information gathered from telephone calls with study personnel.
- •A self-reported illness narrative of recovery to prior health after a SARS/CoV2 infection.
- •Laboratory documentation of a positive COVID-19 PCR, NAA, or other EUA Approved test to confirm active COVID infection at the time of the SARS-CoV-2 infection. Participants with positive home tests during Phase A will be required to have a positive anti-SARS nucleocapsid antibody test.
- •Meets WHO Clinical Progression Scale of 2 - 6:
- •2: Ambulatory; symptomatic, independent
- •3: Ambulatory; symptomatic, assistance needed
- •4: Hospitalized; no oxygen therapy
- •5: Hospitalized; oxygen by mask or nasal prongs
- •6: Hospitalized; oxygen by non-invasive ventilation or high flow oxygen
- •Functional Criteria: No substantial symptom severity as determined using SF-36v2: score of >=85 physical function subscale, and >=85 on role physical subscale, and >=85 on social function subscale.
- •Determined to be a Healthy Comparator by the 000089 Case Adjudication Committee
- •Does not have an active SARS-CoV-2 infection. The protocol will conform with NIH CC standards for documenting a participant does not have active SARS-CoV-2 infection. This may include screening interviews and/or testing. Testing may be repeated with each admission. Participants may be rescreened 6 weeks after acute infection has resolved.
- •Neurologic Post-Acute Sequelae of COVID-19 Participants (Neuro-PASC):
- •Six persons with ongoing neurological complaints following an acute SARS-CoV-2 infection.
- •Inclusion criteria:
- •Participants 18 and older
- •Ability to provide informed consent
- •Completed participation in Phase B of Protocol 000089
- •Met 000089 Inclusion criteria for Mild to Moderate COVID-19 with PASC symptoms:
- •Licensed Independent Practitioner documentation of a stable state of general well-health and physical function prior to contracting SARS-CoV-
- •This may include medical records, correspondence letters, or information gathered from telephone calls with study personnel.
- •A self-reported illness narrative of the development of persistent PASC symptoms after recovering from a SARS-CoV-2 infection. These include symptoms such as fatigue, cognitive difficulties, orthostatic intolerance, unrefreshing sleep, neuropathic pain, mood change, and post-exertional malaise.
- •Laboratory documentation of a positive COVID-19 PCR, NAA, or other EUA Approved test to confirm active COVID infection at the time of the SARS-CoV-2 infection. Participants with positive home tests during Phase A will be required to have a positive anti-SARS nucleocapsid antibody test .
