Porphyric neuropathy can be a challenging diagnosis as neurological manifestations can be similar to Guillain–Barré syndrome. This case report describes a patient with recurrent weakness after infection, which was ultimately diagnosed as porphyric neuropathy. Case presentation: A 65-year-old female of Hispanic ethnicity developed acute respiratory failure and quadriplegia. She had a similar presentation several months prior and initially was diagnosed with an acute motor axonal neuropathy variant of Guillain–Barré syndrome. Given the recurrent attacks, tea-colored urine, dysautonomia, and syndrome of inappropriate secretion of antidiuretic hormone, acute intermittent porphyria was considered in the differential diagnosis. Urinary porphobilinogen, delta-aminolevulinic acid, and uroporphyrin were measured and found to be elevated, leading to the diagnosis of porphyria. Gene tests for eight different types of porphyria were negative. Although mutations could not be identified in this patient, acute intermittent porphyria could not be excluded because of the acute attacks and the biochemical abnormality correlates. Conclusions: Even though porphyric neuropathy can be a challenging diagnosis, accurate diagnosis is crucial to avoid permanent damage to peripheral nerves and prevent life-threatening attacks.","PeriodicalId":90076,"journal":{"name":"US neurology","volume":"16 1","pages":"66"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67612600","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}

Recently, three novel immunotherapies have emerged with positive results from phase III randomized trials for relapse reduction in NMOSD. Eculizumab (complement inhibitor) added to stable immunosuppressant therapy significantly reduced the risk of relapse in patients with aquaporin-4 immunoglobulin G (AQP4-IgG)-seropositive NMOSD when compared with addition of placebo, but did not demonstrate a change in disability outcomes. Inebilizumab (anti-CD19 antibody targeting B cells) monotherapy significantly increased the time to first NMOSD attack when compared with placebo, and conferred favorable disability outcomes (reduction in disability progression) and fewer NMOSD-associated inpatient hospitalizations. Satralizumab (interleukin-6 receptor inhibitor), added to baseline immunosuppressant therapy, lowered the risk of NMOSD relapse, when compared with adding to placebo, in a study including adolescents. Safety signals emerged in each trial, including rare deaths in the eculizumab and inebilizumab trials. Individual selection of the best preventative therapy for patients will require careful consideration of several factors including AQP4-IgG serostatus, previous immunotherapies, medical comorbidities, and physician and patient preferences. Further work is needed to determine long-term efficacy and safety, but these immunotherapies have formally expanded the armamentarium for treatment of this rare and severe central nervous system neuroinflammatory disorder.","PeriodicalId":90076,"journal":{"name":"US neurology","volume":"16 1","pages":"38"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67612511","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}
