As production of plasma-derived medicinal products (PDMPs) can take up to a year, shortages in source plasma donations may not be immediately appreciated. Given current shortages in PDMPs, in particular albumin, we examined the impact of COVID-19 on source plasma donations. Our data demonstrate that source plasma donations were disproportionately impacted by COVID-19 and that these shortages remained until the latter half of 2022. Given the time delay in PDMP manufacturing, these results suggest that while source plasma donation levels are returning to pre-pandemic levels, shortages in PDMPs may not be quickly overcome.

We present a case of extreme leukocytosis (&gt;1 million/μL) in a previously diagnosed CLL patient. Due to symptomatic leukostasis, she was started on cytoreductive therapies including leukocytapheresis. After three rounds of leukocytapheresis (LCP) and concurrent chemotherapy, her white blood cell count decreased from a maximum 1262 × 10<sup>3</sup>/μL to 574 × 10<sup>3</sup>/μL.

GBS classically presents with acute, progressive, ascending weakness, reduced to absent reflexes, and albuminocytological dissociation on cerebrospinal fluid (CSF) analysis. Botulism is a neurotoxin-mediated acute descending flaccid paralysis with cranial nerve palsies and dysautonomia. Botulism in adults is caused by ingestion/inhalation of botulinum toxin or wound infection with <i>Clostridium botulinum</i>. Both GBS and botulism can rapidly precipitate respiratory failure; thus, prompt diagnosis and treatment are crucial to mitigate poor outcomes. Herein, we describe a case of botulism initially diagnosed as GBS given classic laboratory features, and describe the importance of careful consideration of the most appropriate therapeutic modalities in cases of acute flaccid paralysis, particularly regarding empiric administration of botulinum antitoxin and use of intravenous immune globulin in lieu of plasma exchange for potential GBS to prevent removal of antitoxin.</p>","PeriodicalId":15390,"journal":{"name":"Journal of Clinical Apheresis","volume":"38 6","pages":"760-763"},"PeriodicalIF":1.5,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9897852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
