Structured, expert-informed selection and harmonization of patient-reported outcome measures (PROMs) in a German multicenter network: the post-COVID syndrome use case

Patient-reported outcome measures (PROMs) provide subjective information on symptoms, functional ability or quality of life. In post-COVID syndrome (PCS), lacking clear diagnostic criteria or biomarkers, PROMs enable a differentiated assessment of disease course and treatment effects. Within a multicenter research proj...

Persistent Neurological Symptoms After COVID-19 Lack Evidence of Adaptive CNS Immune Activation

Persistent neurological symptoms are among the most disabling manifestations of post-COVID-19 syndrome (PCS), yet the contribution of ongoing CNS immune activation remains uncertain. CSF studies including clinically relevant COVID-19 recovered control cohorts are scarce. In this prospective single-center study, we enro...

Bi-compartmental CSF-serum analysis of NfL and GFAP differentiates central and peripheral pathology in neuroinfectious diseases: A monocentric real-world cohort study.

Neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP), established biomarkers of neuroaxonal injury and astroglial pathology, are frequently only assessed in blood, which limits conclusions regarding their origin. Bi-compartmental analyses of CSF and serum may help differentiate central or peripher...
