Immunosuppressive therapy and plasma exchange showed limited benefit, and the anti‐acetylcholine receptor antibody titer peaked to 130 nmol/L. Seven cycles of efgartigimod treatment were administered, which improved the symptoms, achieving a Myasthenia Gravis‐Actvities of Daily Living score of 0. The anti‐acetylcholine receptor antibody titer fluctuated until the end of the fifth cycle, thereafter, plateauing at 22 nmol/L. These findings allowed the prednisolone dose to be tapered and the interval between the treatment cycles to be increased.","PeriodicalId":19154,"journal":{"name":"Neurology and Clinical Neuroscience","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140379305","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}

History of smoking (p < 0.05) and bulbar onset (p < 0.001) were risk factors for rapid progression and poor prognosis. Baseline ALSFRS‐R score (p < 0.001) and total MRC score (p < 0.05) were positively related to mean survival time of included patients. Neither comorbidities nor intake of antihypertensive drugs, antidiabetics, and statins as dependent variables showed considerable influence on ALS progression or survival.Our study revealed early onset and long diagnostic delay were indicators of slow progression and long survival. Smoking and bulbar onset were risk factors for shorter survival times and abstaining from smoking was beneficial to patients with ALS in improving median survival time. Long‐term intake of riluzole should be recommended for affordable patients.","PeriodicalId":19154,"journal":{"name":"Neurology and Clinical Neuroscience","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140382447","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}

GS is associated with several neurological conditions including epilepsy. Individuals with GS often exhibit a genetic predisposition associated with human leukocyte antigens (HLA) (Cecilio & Bonatto, Arq Bras Cir Dig, 28, 2015, 183). The purpose of this study was to investigate the prevalence of GS based on HLA genotyping in patients with epilepsy (PWE).In total, 50 PWE and 50 controls were recruited. DNA was extracted from the venous blood samples and genotyped for HLA‐DQ2.2, DQ2.5, DQ7 and DQ 8. In this study, GS was diagnosed if any subject showed positive for one or more of the HLA‐DQ alleles. The type of epilepsy and number of antiseizure medication (ASM) used were recorded.Only 2 alleles (HLA‐DQ 2.2 & HLA‐DQ8) were detected among 46 out of 100 subjects. 18 PWE and 19 controls were positive for HLA‐DQ8 (p = 0.836). 9 of the PWE, but no controls were positive for HLA‐DQ 2.2 (p = 0.003). 8 of these 9 PWE who were positive for HLA‐DQ 2.2 were also positive for HLA‐DQ8 (double positive), and these patients required multiple ASM for seizure control (p = 0.006).HLA‐DQ2.2 was seen highly prevalent in PWE. The double positives required more than one ASM for seizure control postulating malabsorption of ASM in these individuals. These findings suggest that HLA‐DQ genotyping may be a valuable additional test in PWE especially in those needing more than one ASM. Prescribing gluten‐free diet (GFD) to PWE with GS may potentially be an additional measure to achieve seizure control.","PeriodicalId":19154,"journal":{"name":"Neurology and Clinical Neuroscience","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140226194","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}

After his latest relapse, ravulizumab was administered to prevent relapse. Serum classical 50% hemolytic complement activity decreased below detectable levels (<10 U/mL) within 1 h of ravulizumab injection.
