FILE – This undated, colorized electron microscopy image made available by the National Institutes of Health in February 2020 shows the novel coronavirus SARS-CoV-2 shown in yellow, and the novel coronavirus SARS-CoV-2 shown in blue/pink. Cells emerging from the surface of the indicated cells and cultured are shown. Laboratory. The sample was isolated from a patient in the U.S. During the Omicron era, a study of about 10,000 Americans aimed at helping scientists better understand this mysterious condition. Thursday, May 25, 2023, in JAMA, the risk of long-term infection with the new coronavirus is lower than in earlier waves of the pandemic. (His NIAID-RML via AP, File)
(news nation) – new the study sheds light on the near-permanent fatigue experienced by people suffering from long-term coronavirus infections.
Researchers from Amsterdam UMC and Vrije Universiteit Amsterdam, published in Nature Communications, found that persistent fatigue in patients with long-term COVID-19 infection has a biological cause. It is the mitochondria in muscle cells that produce less energy than in healthy patients.
for study, asked 25 long-term coronavirus patients and 21 healthy participants to ride a stationary bike for 15 minutes. People who had been infected with the new coronavirus for a longer period had symptoms that worsened over a longer period of time.
“We observed a variety of abnormalities in the patient's muscle tissue. At the cellular level, we found that the mitochondria in the muscles, also known as the energy factories of the cell, functioned poorly, resulting in reduced energy production. ” said Rob Wust, assistant professor in the Department of Human Movement Sciences. Vieux University. “So the cause of fatigue is actually biological.
In August, the National Institutes of Health (NIH) launched several studies to test possible treatments for this mysterious condition that afflicts millions of people.
scientists still don't know What is the cause of the prolongation of the new coronavirus infection?, an umbrella term for approximately 200 different symptoms. It is estimated that between 10% and 30% of people experience some form of long-term COVID-19 infection after recovering from coronavirus infection, and this risk is slightly lower than at the beginning of the pandemic. are doing.
