Proteinorachy (462 mg/dL; N < 45), proteinuria (3.5 g/g creatine), and biopsy-proven membranous nephropathy were identified. Intravenous immunoglobulins, corticosteroids, and plasmaphereses did not allow recovery. Anti-CNTN1 immunoglobulin G4 (IgG4) assay was positive. Rituximab (375 mg/m2/week, 4 weeks) provided obvious improvement. Relapsing–remitting anti–CNTN1-CIDP co-occurring with nephrotic syndrome is exceptional, and its identification is essential because efficient therapies such as rituximab are available for this severe condition.","PeriodicalId":39645,"journal":{"name":"Journal of Clinical Neuromuscular Disease","volume":"23 1","pages":"219 - 226"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41839824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Her testing demonstrates a non-length-dependent axonal sensorimotor polyneuropathy affecting predominantly the upper extremities with active denervation of the distal muscles of both arms. It is important to highlight these findings because most genetic neuropathies have a length-dependent pattern of involvement, affecting the distal legs before the arms. The electrodiagnostic findings in RTD2 have not been previously well described. These electrodiagnostic findings are in agreement with the typical clinical phenotype of RTD2, which affects the upper limbs and bulbar muscles more than the lower extremities.","PeriodicalId":39645,"journal":{"name":"Journal of Clinical Neuromuscular Disease","volume":"23 4 1","pages":"205-209"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46712485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sixteen years after symptom onset, rituximab was administered at 2 g/m2 over 2 weeks. No significant progression of disease has occurred over the following 10 years despite no additional treatments, including intravenous immunoglobulin, being given.
