Studie finner ingen utbredd hjärninflammation vid långtidscovid

Forskare i Finland har inte funnit några bevis för utbredd hjärninflammation hos personer med långtidscovid. Resultaten kopplar i stället svårare symtom till ökad aktivitet i hjärnområden som är kopplade till känslor och minne.

Ett team vid Åbo universitet undersökte 14 personer med långtidscovid med hjälp av PET- och MR-kameror. De jämförde resultaten med skanningar från 11 friska frivilliga och 13 patienter med multipel skleros. Inga betydande skillnader i markörer för hjärninflammation framkom mellan gruppen med långtidscovid och kontrollgruppen med friska deltagare. Patienterna med långtidscovid uppvisade också betydligt mindre inflammation i den vita substansen än gruppen med multipel skleros.

Researchers analyzing immune cells from people with long COVID have identified a distinct molecular state in CD14+ monocytes—labeled “LC-Mo”—that was more prevalent among patients whose initial COVID-19 illness was mild to moderate and that tracked with reported fatigue and respiratory symptoms, along with higher levels of inflammatory signaling molecules in blood plasma.

New research indicates that severe cases of COVID-19 or influenza can alter lung immune cells, potentially increasing cancer risk months or years afterward. The study, conducted by scientists at the University of Virginia, highlights the role of chronic inflammation in this process and emphasizes vaccination as a preventive measure. Findings suggest closer monitoring for affected patients to enable early detection.

Researchers at the University of California, San Francisco have identified how aging lungs contribute to severe flu and COVID-19 outcomes in older adults. Their study shows that lung fibroblasts trigger excessive inflammation, forming damaging clusters of immune cells. The findings, published in Immunity on March 27, suggest potential new treatments.

Scientists at the University of Southern California have found experimental compounds that may reduce harmful brain inflammation associated with Alzheimer’s disease. The work focuses on the enzyme cPLA2 and people who carry the high-risk APOE4 gene.

A study of 440 participants from the Women’s Interagency HIV Study found that accelerated epigenetic aging in monocytes—an immune cell type—tracked more closely with emotional and cognitive depression symptoms such as hopelessness and loss of pleasure than with physical symptoms like fatigue. The work, published in The Journals of Gerontology: Series A, adds evidence that cell-type-specific aging measures could contribute to future biological tools to complement symptom-based depression screening, though researchers say more validation is needed before clinical use.
