Addition of fresh serum to plasma to aid in enhancement of complement-dependent antibodies

Principle Given the right conditions, antibodies in several blood group systems will activate complement once bound to red blood cells (RBCs), with most having the ability to activate complement to the C3 stage. Examples of antibodies that can activate complement include those in the Kidd, Kell, Duffy, and Lewis blood group systems. Complement activation is of importance in immunohematology testing because it can enable the antibody to act as a hemolysin in vitro or to bind complement that may

Review: complement receptor 1 therapeutics for prevention of immune hemolysis

The complement system plays a crucial role in fighting infections and is an important link between the innate and adaptive immune responses. However, inappropriate complement activation can cause tissue damage, and it underlies the pathology of many diseases. In the transfusion medicine setting, complement sensitization of RBCs can lead to both intravascular and extravascular destruction. Moreover, complement deficiencies are associated with autoimmune disorders, including autoimmune hemolytic

CD59: A long-known complement inhibitor has advanced  to a blood group system

The blood group system number 35 is based on CD59, a 20-kDa membrane glycoprotein present on a large number of different cells, including erythrocytes. The major function of CD59 is to protect cells from complement attack. CD59 binds to complement components C8 and C9 and prevents the polymerization of C9, which is required for the formation of the membrane attack complex (MAC). Other functions of CD59 in cellular immunity are less well defined. CD59 is inserted into the membrane by a

Quantitation of red cell-bound immunoglobulins and complement in lymphoma patients

Quantitative ELISA may be useful for determining the amount of red blood cell (RBC)-associated immunoglobulins (Igs) in patients with autoimmune hemolytic anemia (AIHA). In idiopathic AIHA, there is about 20 times more RBC-associated IgG and complement than in normal persons. In patients with low-grade lymphomas (particularly, B-CLL and splenic marginal zone lymphoma) autoimmune hemolysis is a component of their anemia. In highgrade malignant lymphomas (i.e, diffuse large B-cell lymphoma and

Measurement of red blood cell-bound C3b and C3d using an enzyme-linked direct antiglobulin test

Complement has a complex role in immune mediated red blood cell (RBC) destruction and usually induces extravascular hemolysis of C3bcoated RBCs by erythrophagocytosis and by acting synergistically with cell-bound immunoglobulins. A sensitive two-stage enzyme-linked direct antiglobulin test (ELDAT) was developed and used to measure RBC-bound C3b and C3d in 120 healthy adult individuals and in 60 patients suffering from a variety of conditions, including warm- and cold-type autoimmune hemolytic

Review: Cromer and DAF: role in health and disease

The antigens of the Cromer blood group system are located on the protein decay-accelerating factor (DAF). This system consists of ten high-prevalence and three low-prevalence antigens; the molecular basis for all of these antigens is a single nucleotide polymorphism in the DAF gene. DAF is a 70,000-Da plasma membrane protein that is widely distributed on all blood cells and on endothelial and epithelial tissues. The physiological role of DAF is to inhibit the complement cascade at the level of

That patient’s RBCs had IgG and complement on the surface, while those of the other patient had IgG without complement. Functional asplenism may diminish the role of an IgG autoantibody that does not bind complement, since RBCs coated with complement are removed by the liver. Therefore, complement-binding autoantibodies may have particular

A review of the Chido/Rodgers blood group system published in 2010 summarized the discovery of this blood group,1 with the eventual recognition that Chido/Rodgers antigens were not intrinsic red blood cell (RBC) antigens but were epitopes carried on the C4 component of complement. In normal homeostasis, fragments of the C4 protein (C4b) are deposited on the RBC membrane and on other tissues as well. C4b is then broken down to C4d. Thus, with anti-Ch or anti-Rg, agglutination with indirect

Cromer-related blood group antigens and the glycosyl phosphatidylinositol-linked protein, decay-accelerating factor DAF (CD55)

Cromer-related blood group antigens are located on the complement regulatory glycoprotein, decay-accelerating factor (DAF). DAF is not detectable on red cells from individuals with a Cromernull phenotype (termed Inab), which is probably an inherited condition. DAF is also absent from a subpopulation of red cells (PNH III) from patients with paroxysmal nocturnal hemoglobinuria (PNH), an acquired hematological defect.

ZZAP treatment of red blood cells

Principle ZZAP is a mixture of a sulfhydryl reagent (dithiothreitol [DTT]) and a proteolytic enzyme (papain or ficin). It was first described by Branch and Petz in their 1982 article in the American Journal of Clinical Pathology.1 ZZAP is used to dissociate IgG and complement from red blood cells (RBCs), an action that neither reagent can achieve alone. According to Branch and Petz, it is believed that ZZAP “reduces interchain disulfide linkages, increasing exposure of the IgG polypeptides to

However, limitations of the research about the construct validity of adolescent BPD have also been identified, most notably regarding the delimitation of adolescent BPD from other disorders as well as a lack of longitudinal and family studies.Given these limitations and the limitations of the Robins and Guze approach to psychiatric nosology, we recommend exploring the potential of the National Institute of Mental Health Research Domain Criteria as a complement

the dependence of the probability of nonresponse on unobserved or missing observations. The main aim of the paper is to consider how to account for the joint effects of informative sampling designs and notmissing-at-random response mechanism in statistical models for complex survey data. For this purpose, theoretically, we use the response distribution and relationships between the moments of the superpopoulation, the sample, sample-complement, response, and nonresponse distributions for the

Prednisolone was the mainstay of treat­ment, and was occasionally augmented with azathioprine and intra­venous immunoglobulin. Blood transfusion was required in two patients, both of whom eventually required splenectomy that result­ed in full remission. The one patient with mild hemolysis recovered without treatment.

MMA results using sera from days 0, 3, and 9 were 2.7 and 5.5, 0.8 and 4.8, and 3.0 and 3.7 percent, respectively, without and with added fresh normal serum as a source of complement (clinical significance = > 3% reactivity). The subclass of the anti-Dib was IgG1. This is the first documentation of the clinical significance of an anti-Dib.

The significance of a positive DAT in thalassemia patients

The DAT is performed for the detection of antibody or complement on the surface of RBCs. Our institution previously performed DATs on all chronically transfused thalassemia patients before each transfusion episode to detect early alloimmunization. The medical records of all thalassemia patients treated at our institution from 2004 to 2007 were reviewed to determine the significance of the high rate of positive DATs (52.5% of 80 patients). The majority of IgG-reactive DATs were associated with a

Autoimmune hemolytic anemia caused by warm-reacting IgM-class antibodies

Warm IgM autoantibodies occur in association with IgG-class and/or IgA-class immunoglobulins in approximately 30 percent of patients with warm-type autoimmune hemolysis. They may be classified as agglutinins or hemolysins, which may be incomplete or complete, depending on in vitro serology; they almost always bind complement. Autoimmune hemolytic anemia solely due to warm IgM autoantibodies is exceedingly rare. We report two cases of the incomplete agglutinin type. The autoantibodies were

Isolation of Sabin-like Polioviruses from Sewage in Poland

As a complement to the active search for cases of acute flaccid paralysis, environmental sampling was conducted from January to December 2011, to test for any putative polio revertants and recombinants in sewage. A total of 165 environmental samples were obtained and analyzed for the presence of polioviruses by use of cell culture (L20B, RD and Caco-2) followed by neutralization and reverse-transcription polymerase chain reaction. Out of the 31 CPE positive samples, 26 contained one and 5 two

The sensitivity, specificity, and clinical relevance of gel versus tube DATs in the clinical immunology laboratory

The DAT is a test used to demonstrate in vivo antibody and/or complement coating of RBCs. Typically, the DAT is performed in test tubes; however, recently a number of commercially available tests using gel-filled microtubes have become available. Few data comparing the sensitivity of these test media are available. To compare the rate of detection of a positive DAT performed in test tubes versus in gel-filled microtubes and to assess the clinical significance of the results in patients
