Cold agglutinins are autoantibodies that agglutinate red blood cells at low temperatures, leading to haemagglutination and haemolysis. They are generally of no clinical significance. However, when people with cold agglutinins undergo cardiac operation with hypothermia and cold cardioplegia, they can experience complications. Thus, different perioperative management is required for such patients. We describe a 74-year-old man with cold agglutinins incidentally detected on the preoperative screening test. He had never experienced any complications or developed a haematological disease...

The aim of this study was to optimize the conditions for the extraction of low-abundance proteins (LAPs) and the removal of abundant proteins (APs; β-conglycinin and glycinin) from soybean meal. Single factor and orthogonal experiments were designed to determine the effects of four factors (isopropanol concentration, total extraction time, ultrasonic power, and ultrasonic time) on protein concentration in isopropanol extracts. Proteins in the isopropanol supernatant and the cold acetone precipitate of isopropanol were identified by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF-MS)...

We report a case of secondary cold agglutinin disease (CAD) due to pulmonary tuberculosis in a 68-year male patient who presented with acrocyanosis involving both upper limbs and greater portion of lower limbs. Direct Coombs' test was positive with mild anemia and the cold agglutinin titer was high. Sputum showed numerous acid fast bacilli per high power field. The patient was given standard anti-tuberculous treatment (ATT) and his symptoms gradually improved. After nine months of ATT, his haemoglobin improved, acrocyanosis resolved completely and cold agglutinin titer decreased in level...

Immune hemolytic anemia is characterized by clinical and laboratory features of hemolytic anemia with direct antiglobulin test (DAT) positivity. It could be autoimmune hemolytic anemia (AIHA), alloimmune, or drug-induced hemolysis based on the antigenic stimulus. Furthermore, based on thermal amplitude of autoantibody, AIHA is classified as warm (65%), cold (30%), and mixed (5%) type. Mixed AIHA is extremely rare in children and must be differentiated from warm AIHA with clinically insignificant cold agglutinins and cold hemagglutinin disease as their treatment is different...

Cardiac surgery on a patient with cold agglutinin disease is high risk for thromboembolism due to hypothermia perioperative. A 75-year-old woman with cold agglutinin disease underwent aortic valve replacement for severe aortic stenosis. Cold antibody was detected by preoperative screening test for blood transfusion. In order to prevent thromboembolic event during the operation, we maintained rectal temperature at around 36 degrees centigrade during the cardiopulmonary bypass by warming blood in the bypass circuit...

Glomerulonephritis as well as kidney injury secondary to fulminant intravascular hemolysis are rare extrapulmonary manifestations of Mycoplasma pneumoniae infection. We describe a 50-year-old female diagnosed with M. pneumoniae infection-associated hemolytic anemia, characterized by negative cold agglutinin tests but with laboratory evidence of complement alternative pathway activation. The patient presented both with anemia and severe kidney failure and she was treated with steroids and red blood cell transfusions along with plasmapheresis...

INTRODUCTION: Landsteiner ABO system of blood groups is most important for transfusion medicine and has subtypes of A Antigen, A1 and A2, upon which further groups of A and AB have been classified. Of individuals with A antigen, approximately 20% belong to A2 while rest 80% belong to A1. Anti-A1 Lectin, a cold agglutinin which destroys A1 cells is clinically significant when they react at 37°C, causing transfusion reactions. AIM: To assess the prevalence of A1 and A2 subgroups in the population...

BACKGROUND: The Monocyte Monolayer Assay (MMA) is an in vitro simulation of red blood cell (RBC) alloantibody behavior. It has been classically applied to predict the risks of post-transfusion hemolytic reactions when transfusing incompatible RBC units. Quantifying erythrophagocytosis by MMA may be an interesting option for situations where there is doubt whether a RBC autoantibody is mediating significant hemolysis. Here, we present three situations involving RBC autoantibodies in which the MMA was decisive for clarifying the diagnosis and choosing the best clinical treatment...

Primary chronic cold agglutinin disease (CAD) is a well-defined clinicopathologic entity in which a bone marrow clonal B-cell lymphoproliferation results in autoimmune hemolytic anemia and cold-induced circulatory symptoms. Rituximab monotherapy and fludarabine-rituximab in combination are documented treatment options. In a prospective, nonrandomized multicenter trial, 45 eligible patients received rituximab 375 mg/m(2) day 1 and bendamustine 90 mg/m(2) days 1 and 2 for 4 cycles at a 28-day interval. Thirty-two patients (71%) responded; 18 (40%) achieved complete response (CR) and 14 (31%) partial response (PR)...

Primary chronic cold agglutinin disease (CAD) is an autoimmune haemolytic anaemia in which a specific bone marrow lymphoproliferative disorder causes production of cold agglutinins (CA). Binding of CA to erythrocyte surface antigens results in a predominantly extravascular haemolysis that is entirely complement dependent. Because of complement activation, exacerbations are common during febrile infections, trauma or major surgery. Involvement of the terminal complement pathway with C5-mediated intravascular haemolysis is probably not prominent in stable disease but is supposed to be of importance in exacerbations following acute phase reaction...

Diffuse panbronchiolitis (DPB) and asthma are obstructive airway diseases, the former being characterized by Th1-type and the latter by Th2-type airway inflammation. Differential diagnosis is often a problem, but coexistence has rarely been reported. A 76-year-old man with asthma was admitted to our hospital because of one-month history of dyspnoea on exertion with bilateral diffuse granular shadows. He also had a history of chronic sinusitis. Auscultation of the lungs showed coarse crackles and wheezes. Laboratory data revealed an elevated total serum immunoglobulin E and a high titre of cold agglutinin...

Epstein-Barr virus, a member of the Herpesviridae family, is responsible for the infectious mononucleosis clinical syndrome, which mainly includes the pharyngitis, fever, and lymphadenopathy triad after incubation for 30-50 days. The liver is involved in 80-90% of patients in a self-limiting transient manner, with jaundice being much more uncommon (5%). From a hematological standpoint it may manifest aplastic anemia, neutropenia, and thrombocytopenia. We report a case of infectious mononucleosis that included severe acute hepatitis and was associated with severe hemolytic anemia secondary to cold agglutinins...

Splenic marginal zone lymphoma (SMZL) is a rare low-grade B-cell lymphoma accounting for less than 1% of lymphoid neoplasms and is often associated with autoimmune disorders. A 48-year-old woman presented with severe anemia due to steroid-refractory cold agglutinin disease (CAD), and was referred to our hospital for management of progressive systemic illness and high fever. On admission, she showed elevated serum soluble IL-2R and mild splenomegaly. PET/CT revealed FDG accumulation in the spleen and bone. She was pathologically diagnosed as having splenic marginal zone lymphoma by splenectomy and received 8 cycles of rituximab every 2 weeks, resulting in marked improvement of anemia...

A broad spectrum of diseases are associated with IgM monoclonal gammopathy, including Waldenstrom macroglobulinemia (WM), various types of B cell non-Hodgkin's lymphoma (NHL), multiple myeloma (MM), primary amyloidosis (AL), and monoclonal gammopathy of undetermined significance (MGUS); these are called IgM monoclonal gammopathy related diseases (IgM-RD). We investigated MYD88 L265P and WHIM-like CXCR4 mutations in various IgM-RD. Patients with serum immunofixation electrophoresis confirmed IgM monoclonal gammopathy who had enough material for DNA extraction and presented between January 2008 and October 2016 at Peking Union Medical College Hospital were enrolled in this cohort...
