Due to the potential side effects of steroids and abnormal blood sugar levels, we started intravenous immunoglobulin (IVIG) therapy (400mg/kg/day-monthly) with moderate doses of prednisolone.","PeriodicalId":85078,"journal":{"name":"Laboratory hematology : official publication of the International Society for Laboratory Hematology","volume":"20 2","pages":"7-8"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32484754","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}

Eryptosis, the suicidal death of RBCs, is characterized by cell shrinkage, membrane blebbing, and cell membrane phospholipids scrambling with PS exposure at the cell surface. Erythrocytes exposing PS are recognized, bound, engulfed, and degraded by macrophages. Eryptosis thus fosters clearance of affected RBCs from circulating blood, which may aggravate anemia in pathological conditions. Thalassemia patients are more sensitive to the eryptotic depletion and osmotic shock which may affect RBC membrane phospholipid asymmetry. We aimed in this work to determine the RBC PS exposure in splenectomized and nonsplenectomized β-thalassemia major (β-TM) patients and correlate it with the clinical presentation and laboratory data. RBCs were stained for annexin V to detect phosphatidylserine (PS) exposure in 46 β-TM patients (27 splenectomized and 19 nonsplenectomized) compared to 17 healthy subjects as a control group. We observed a significant increase in RBC PS exposure in β-TM patients compared to control group (P = .0001). Erythrocyte PS exposure was significantly higher in splenectomized β-TM patients compared with nonsplenectomized β-TM patients (P = .001). No correlation was found between RBC PS exposure and clinical or hematological data of β-TM patients, but there was a positive correlation between RBC PS exposure and ferritin level in β-TM patients have higher levels of RBC PS exposure, and splenectomy was shown to aggravate RBC PS exposure without aggravation of anemia. </p>","PeriodicalId":85078,"journal":{"name":"Laboratory hematology : official publication of the International Society for Laboratory Hematology","volume":"20 2","pages":"9-14"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32484755","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}

This mobilization is dependent upon bone remodeling, the proteolytic enzymes of bone marrow-derived stromal cells, and adhesion molecules such as integrin, but the main mechanisms controlling this traffic are still unclear. The nervous system, as the most important regulator of the body, can affect the mobilization network by secreting catecholamines, so that denervation of catecholaminergic fibers in the BM of mice could lead to declining mobilization in steady state and stress situations, even in the presence of other intact environmental factors in the BM. Thus, due to the importance of the nervous system, we have attempted to give a general overview of how the nervous system is involved in the mobilization of HSCs in this review. Then, we will try to describe the mobilization process induced by the nervous system, which consists of 3 mechanisms: stromal cell-derived factor 1 (SDF-1)/CXC chemokine receptor type 4 (CXCR4), proteolytic enzymes, and bone remodeling. </p>","PeriodicalId":85078,"journal":{"name":"Laboratory hematology : official publication of the International Society for Laboratory Hematology","volume":"19 3","pages":"8-16"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1532/LH96.12013","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40272468","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}
