FC has a great impact in the field of transfusion medicine (TM) due to its ability to analyze individual cell population and cell epitopes by sensitive, reproducible, and objective methodologies. The main uses of FC in TM are detection of fetomaternal hemorrhage, diagnosis of paroxysmal nocturnal hemoglobinuria, quantification of D antigen, detection of platelet antibody, quality control of blood components, for example, residual leukocyte counts and evaluation of CD34-positive hematopoietic progenitor cells in stem cell grafts. In recent years, FC has been implemented as an alternative method for the detection and characterization of red cell autoantibodies in autoimmune hemolytic anemia. Many workers considered FC as a very good complement when aberrant expression of various erythrocyte antigens needs to be elucidated. It has been extensively used in the resolution of ABO discrepancies and chimerism study. FC has also been used successfully in various platelet immunological studies. In the recent past, FC has been used in several studies to assess the platelet storage lesions and elucidate granulocyte/monocyte integrity and immunology. FC analysis of CD34+ stem cells is now the method of choice to determine the dosage of the collected progenitor cells. The technique is vastly used to evaluate residual leukocytes in leukodepleted blood components. We conclude that flow cytometers are becoming smaller, cheaper, and more user-friendly and are available in many routine laboratories.

PLEX cycle was repeated till either of the end-points were achieved (i) MELD < 20 for 48 h or reaches below the baseline, whichever is lower, (ii) completed three PLEX cycles, (iii) hemodynamic instability, (iv) or outcome achieved. Outcome of interest was categorized as favorable (discharged in stable condition) or unfavorable (death or discharge in moribund condition). Data are expressed as median (interquartile range).</p><p><strong>Results: </strong>Sixteen patients (age 35 [27-48] years; male 8; ALF 5, ACLF 11; MELD 33 [27-37]; CLIF-SOFA 10 [8.5-12]) were included. Participants received 2 (1-3) cycles of PLEX during 13 (11-25) days of hospitalization. Overall, serum bilirubin, INR, creatinine, MELD, and CLIF-SOFA scores were significantly improved after PLEX. Five patients (5/16, 31%) had complete resolution of HE. Eight patients (50%) had a favorable outcome. Those with favorable outcome had significant improvement in serum bilirubin, INR, and CLIF-SOFA scores as compared to those with unfavorable outcome.</p><p><strong>Conclusion: </strong>PLEX may be effective in patients with ALF or ACLF. More data are needed to establish its role in the management of liver failure.</p>","PeriodicalId":42296,"journal":{"name":"Asian Journal of Transfusion Science","volume":"16 2","pages":"209-213"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/28/4a/AJTS-16-209.PMC9855211.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9148707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
