Brief Summary

Background: Post-Infectious Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (PI-ME/CFS) refers to long-lasting and disabling fatigue or malaise, inability to recover after exercise, and physical and emotional discomfort that may occur after a person has an infection. Researchers want to learn more about its causes. Objective: To learn more about PI-ME/CFS. Eligibility: Adults ages 18-60 years who have finished at least 7th grade education and either: have ME/CFS that started after an infection OR had Lyme disease, were treated, and returned to normal health OR are healthy volunteers Design: Participants will initially have a 2-5 day inpatient visit at the National Institutes of Health Clinical Center in Bethesda. During the visit, participants will have: Medical history Physical exam Intravenous (IV) line. A thin plastic tube is inserted into a vein. Blood and urine collected Magnetic resonance imaging (MRI). Participants will lie in a machine that takes pictures of their brain. They may get a dye through their IV. Grip strength tested Saliva, cheek swab, and stool collected Tilt table test with measures of body functions such as sweating and breathing, blood pressure, and heart rate and blood and urine sample collection Collection of blood cells. Participants can choose to have the blood drawn through the IV or through a machine that filters blood cells and returns the liquid blood back into the participant s vein. Lumbar puncture. Fluid will be removed by placement of a needle between the back bones. Heart monitoring Sleep study for participants with PI ME/CFS Questions about the participant s life and how they are feeling Questions from a neuropsychologist Questions from an occupational therapist for participants with PI ME/CFS Questinos from a nutritionist After the initial visit participants will return home. Participants evaluated for PI-ME/CFS during the first visit will have their information reviewed by an adjudication panel of experts in the diagnosis and care of ME/CFS to determine if they are eligible to participate in the second study visit. Eligible participants will be invited back for a second study visit. If a participant was taking certain medications during the first visit, they may be asked to taper off of them prior to the second visit and report any problems. They will also receive an activity monitor, fatigue diary, and nutrition log to use for at least one week prior to their second visit. Participants who are eligible will return for a 5-10 day inpatient hospital visit at the National Institutes of Health Clinical Center. During the visit, participants will undergo measurements before and up to 96 hours after performing a stationary bike exercise test. The purpose of the exercise test is to provoke ME/CFS symptoms (post-exertional malaise). Tests will be performed before and after exercise testing. These include: Sleeping in a room that measures how the body uses energy with EEG monitoring Eating a controlled diet Performing vigorous exercise for 10-15 minutes Questions about how participants are feeling Questions about what participants usually eat Samples of saliva, blood, urine and stool Wearing an activity monitor Having an Xray that measures body composition Thinking and memory tests Heart monitoring Transcranial magnetic stimulation. A brief electrical current to the scalp creates a magnetic pulse that affects brain activity. Magnetic resonance imaging (MRI). Participants will lie in a machine that takes pictures of their brain. They will do thinking and exercise tasks during the MRI. Lumbar puncture. Fluid will be removed by placement of a needle between the back bones.

Outcome Measures

Primary Outcomes (2)

  • Cardiopulmonary Exercise Test (CPET) - ATVO2rel

    The Relative Volume of Oxygen at the Anaerobic Threshold (ATVO2rel) was determined during a cardiopulmonary exercise test (CPET). ATVO2rel represents the volume of oxygen being consumed when a participant reaches AT, adjusted for their weight during the CPET. Results compared Healthy Volunteer Participants to ME/CFS Participants.

    At time of AT during CPET

  • Cardiopulmonary Exercise Test (CPET) - RER

    The Respiratory Exchange Ratio (VCO2/VO2) was determined during a cardiopulmonary exercise test (CPET). VCO2/VO2 is calculated by measuring the volume of carbon dioxide and oxygen the participant breathes during CPET. When the volume of carbon dioxide exceeds that of oxygen, it reflects a change from aerobic metabolism to anaerobic metabolism. When a participant has a Respiratory Exchange Ratio (RER) during CPET that is equal or greater than 1.1 it is considered a sufficient exercise effort. Results compared Healthy Volunteer Participants to ME/CFS Participants.

    At time of AT during CPET
