Autoimmune hemolytic anemia (AIHA) is an uncommon disorder characterized by hemolysis mediated by autoanti-bodies directed against self-red blood cells (RBC), with the incidence of 1–3 per 100,000/year and mortality rate of approximately 11% [1, 2]. AIHA is ...

PURPOSE The purpose of this study was to report a novel model for comparing mechanical resistance to intraocular pressure (IOP) increases with 23-gauge (23G) and 25G transconjunctival sutureless vitrectomy (TSV) sclerotomies in the immediate postoperative period using an experimental model of a vitrectomized eye. METHODS This was a prospective, experimental, randomized, and observer-masked ex...

OBJECTIVES Although a large gauge needle can procure more tissue at endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), its advantage over smaller needles is unclear. This study compared flexible 19G and 25G needles for EUS-FNA of solid pancreatic masses. METHODS This was a randomized trial of patients undergoing EUS-FNA of pancreatic masses using flexible 19G or 25G needle. Main o...

BACKGROUND Biopsy needles have recently been developed to obtain both cytological and histological specimens during endoscopic ultrasound (EUS). We conducted this study to compare 22-gauge (G) fine needle aspiration (FNA) needles, which have been the most frequently used, and new 25G fine needle biopsy (FNB) needles for EUS-guided sampling of solid pancreatic masses. METHODS We conducted a re...

Autoimmune hemolytic anemia (AIHA) is the result of increased destruction of red blood cells (RBCs) due to the production of autoantibodies, and it can be life-threatening. To study the mechanisms that trigger AIHA, we used the Marshall-Clarke and Playfair model of murine AIHA, in which mice repeatedly immunized with rat RBCs develop erythrocyte autoantibodies as well as rat-specific alloantibo...

Autoimmune cytopenias occur in up to 10% of patients during the course of chronic lymphocytic leukemia (CLL), with autoimmune hemolytic anemia (AIHA) the most common, followed by immune-mediated thrombocytopenia (ITP). These disorders may occur at any time during disease course and depend on complex interactions between the malignant clone, impaired T-cell function, microenvironment and the imm...

Autoimmune hemolytic anemia (AIHA) is a rare, but clinically significant complication following hematopoietic stem cell transplantation (HSCT). It is characterized by hemolysis due to antibodies produced by the donor’s immune system against donor red cell antigens. The 3-year cumulative incidence of AIHA is 4.44% in adults; however, 75% of patients develop AIHA during the first post-HSCT year [...

Autoimmune haemolytic anaemia (AIHA) in mantle cell lymphoma (MCL) is a rare but life-threatening complication. To date, there are no relevant data for treatment of AIHA in MCL. Ibrutinib, which has been approved for relapse/refractory MCL, is an immunomodulatory drug inhibiting Th2 activation and consequently the production of autoantibodies. We report a case of MCL with AIHA in which this for...

Spherocytic red cells with reduced membrane surface area are a feature of hereditary spherocytosis (HS) and some forms of autoimmune hemolytic anemia (AIHA). It is generally assumed that membrane loss in spherocytic red cells occurs during their sojourn in circulation. The structural basis for membrane loss in HS is improper assembly of membrane proteins, whereas in AIHA it is due to partial ph...

BACKGROUND There has been no report on the clinical features or natural history of autoimmune hemolytic anemia (AIHA) in the Korean adult population. This study retrospectively analyzed the clinical characteristics and long-term outcomes of AIHA in the Korean adults. METHODS Patients newly diagnosed with AIHA between January 1994 and December 2010 at Chungnam National University Hospital were...
