Blood-based biomarkers indicating nerve damage could serve as an additional diagnostic tool to ensure early diagnosis, precise therapeutic monitoring, and a more targeted anti-inflammatory treatment. A potential marker for this purpose is neurofilament light chain (NfL), a marker of neuroaxonal damage that is used as a biomarker in several diseases of the central and peripheral nervous system. NfL has also been suggested to reflect disease activity in patients with vasculitic neuropathy. However, its biodynamics and link to degeneration of peripheral nerve tissue remain unconfirmed. To investigate the usefulness of NfL as a marker of peripheral nerve damage in this context, we retrospectively assembled a cohort of 35 patients undergoing sural nerve biopsies (including patients with vasculitic neuropathy and other neuropathies). We then measured NfL in serum samples cryoarchived at the time of biopsy and correlated NfL levels with histological parameters. For our histological analysis, we quantified parameters of acute axonal degeneration and chronic axonal loss using a combination of manual, threshold-based, and supervised learning-based analyses. We found a significant positive correlation between parameters of acute axonal degeneration and serum-NfL levels that persisted after adjusting for age and concomitant central nervous system disease. We did not find a similar correlation with parameters of chronic axonal loss quantified in nerve biopsies. These findings support the value of NfL as a marker for acute axonal degeneration in patients with vasculitic neuropathy. 000282599 536__ $$0G:(DE-HGF)POF4-353$$a353 - Clinical and Health Care Research (POF4-353)$$cPOF4-353$$fPOF IV$$x0 000282599 588__ $$aDataset connected to CrossRef, PubMed, , Journals: pub.dzne.de 000282599 650_7 $$2Other$$abiomarker 000282599 650_7 $$2Other$$ahistopathology 000282599 650_7 $$2Other$$anerve biopsy 000282599 650_7 $$2Other$$aneurofilament light chain (NfL) 000282599 650_7 $$2Other$$avasculitic neuropathy 000282599 650_7 $$2Other$$avasculitis 000282599 7001_ $$aMeinhardt, Jenny$$b1 000282599 7001_ $$aGimber, Niclas$$b2 000282599 7001_ $$aKestenbach, John$$b3 000282599 7001_ $$aSiewert, Christin$$b4 000282599 7001_ $$aSchmoranzer, Jan$$b5 000282599 7001_ $$aMeisel, Christian$$b6 000282599 7001_ $$aRuprecht, Klemens$$b7 000282599 7001_ $$0P:(DE-2719)2812386$$aHeppner, Frank L$$b8$$udzne 000282599 7001_ $$0P:(DE-2719)2812030$$aKörtvélyessy, Péter$$b9$$udzne 000282599 7001_ $$00000-0002-1143-2103$$aStenzel, Werner$$b10 000282599 773__ $$0PERI:(DE-600)2029927-8$$a10.1111/bpa.70038$$gVol. 36, no. 1, p. e70038$$n1$$pe70038$$tBrain pathology$$v36$$x1015-6305$$y2025 000282599 8564_ $$uhttps://pub.dzne.de/record/282599/files/DZNE-2025-01357.pdf$$yRestricted 000282599 8564_ $$uhttps://pub.dzne.de/record/282599/files/DZNE-2025-01357.pdf?subformat=pdfa$$xpdfa$$yRestricted 000282599 9101_ $$0I:(DE-588)1065079516$$6P:(DE-2719)2812386$$aDeutsches Zentrum für Neurodegenerative Erkrankungen$$b8$$kDZNE 000282599 9101_ $$0I:(DE-588)1065079516$$6P:(DE-2719)2812030$$aDeutsches Zentrum für Neurodegenerative Erkrankungen$$b9$$kDZNE 000282599 9131_ $$0G:(DE-HGF)POF4-353$$1G:(DE-HGF)POF4-350$$2G:(DE-HGF)POF4-300$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bGesundheit$$lNeurodegenerative Diseases$$vClinical and Health Care Research$$x0 000282599 915__ $$0StatID:(DE-HGF)3001$$2StatID$$aDEAL Wiley$$d2024-12-11$$wger 000282599 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2024-08-08T17:07:24Z 000282599 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2024-08-08T17:07:24Z 000282599 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Anonymous peer review$$d2024-08-08T17:07:24Z 000282599 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)1030$$2StatID$$aDBCoverage$$bCurrent Contents - Life Sciences$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)1190$$2StatID$$aDBCoverage$$bBiological Abstracts$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bBRAIN PATHOL : 2022$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bBRAIN PATHOL : 2022$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)0561$$2StatID$$aArticle Processing Charges$$d2024-12-11 000282599 915__ $$0StatID:(DE-HGF)0700$$2StatID$$aFees$$d2024-12-11 000282599 9201_ $$0I:(DE-2719)1810007$$kAG Heppner$$lNeuroimmunology$$x0 000282599 9201_ $$0I:(DE-2719)5000006$$kAG Düzel$$lClinical Neurophysiology and Memory$$x1 000282599 980__ $$ajournal 000282599 980__ $$aEDITORS 000282599 980__ $$aVDBINPRINT 000282599 980__ $$aI:(DE-2719)1810007 000282599 980__ $$aI:(DE-2719)5000006 000282599 980__ $$aUNRESTRICTED
