| Resumen: | Background and ObjectivesTo study the clinical and laboratory features of antineurofascin-155 (NF155)-positive autoimmune nodopathy (AN). MethodsPatients with anti-NF155 antibodies detected on routine immunologic testing were included. Clinical characteristics, treatment response, and functional scales (modified Rankin Scale [mRS] and Inflammatory Rasch-built Overall Disability Scale [I-RODS]) were retrospectively collected at baseline and at the follow-up. Autoantibody and neurofilament light (NfL) chain levels were analyzed at baseline and at the follow-up. ResultsForty NF155+ patients with AN were included. Mean age at onset was 42. 4 years. Patients presented with a progressive (75%), sensory motor (87. 5%), and symmetric distal-predominant weakness in upper (97. 2%) and lower extremities (94. 5%), with tremor and ataxia (75%). Patients received a median of 3 (2-4) different treatments in 46 months of median follow-up. Response to IV immunoglobulin (86. 8%) or steroids (72. 2%) was poor in most patients, whereas 77. 3% responded to rituximab. HLA-DRB1*15 was detected in 91. 3% of patients. IgG4 anti-NF155 antibodies were predominant in all patients; anti-NF155 titers correlated with mRS within the same patient (r = 0. 41, p = 0. 004). Serum NfL (sNfL) levels were higher in anti-NF155+ AN than in healthy controls (36. 47 vs 7. 56 pg/mL, p < 0. 001) and correlated with anti-NF155 titers (r = 0. 43, p = 0. 001), with I-RODS at baseline (r = -0. 88, p < 0. 001) and with maximum I-RODS achieved (r = -0. 58, p = 0. 01). Anti-NF155 titers and sNfL levels decreased in all rituximab-treated patients. DiscussionAnti-NF155 AN presents a distinct clinical profile and good response to rituximab. Autoantibody titers and sNfL are useful to monitor disease status in these patients. The use of untagged-NF155 plasmids minimizes the detection of false anti-NF155+ cases. Classification of EvidenceThis study provides Class IV evidence that anti-NF155 antibodies associate with a specific phenotype and response to rituximab. |
