Ten infants with hemolytic disease of the newborn due to ABO incompatibility were studied. In every case the investigations were undertaken because of jaundice occurring in the first 24 hours of life. The clinical, hematologic and serologic observations in the infants and the serologic findings in the maternal sera are described. Evidence is presented to show that the diagnosis of the disorder rests largely upon the demonstration of spherocytosis, increased osmotic fragility of the red cells, reticulocytosis, and hyperbilirubinemia in a newborn infant whose red blood cells are incompatible with the maternal major blood group isoantibody and against whose cells no other maternal isoantibody is demonstrable. The anti-A or anti-B in each of the maternal sera tested in this series hemolyzed A or B cells in the presence of complement. Other serologic findings in the maternal sera were less consistently demonstrated.

The mother and fetus incompatibility due to Rh-factor, blood group or other blood factors can lead to hemolytic disease of the fetus and newborn (HDN). HDN is a clinical disease condition of the fetus and newborn as a result of hemolysis, when maternal IgG alloantibodies cross the placenta and destroy the red blood cells of the fetus and newborn. The child disease begins in utero and can dramatically increase immediately after birth. As a result, hyperbilirubinemia and anemia develop, that can lead to abortions, serious complications, or death of the neonates in the absence of proper therapy. The range of HDN has changed significantly now compared to previous decades. Half a century ago, HDN was considered an almost complete synonym of RhD-alloimmunization, and this was a frequent problem for newborns. By now due to the high effective of Rh-conflict prevention, immunological AB0-conflicts have become the most common cause of HDN. The review aimes to one of the main causes of jaundice and anemia in neonates at present, i.e. HDN due to immunological AB0-conflict of mother and newborn (AB0-HDN). The main participants of the AВ0- incompatibility mother and child are considered, namely A- and B-glycans, as well as the corresponding anti-glycan alloantibodies. Close attention is paid to the structure features of glycan alloantigens on the red blood cells of the fetus and adult. The possible correlation of the frequency and severity of HDN with the blood group of mother and child, as well as with the titer of maternal alloantibodies, has been considered. The influence of immunoglobulin G subclasses on the AB0-HDN development has been evaluated. In most cases, AB0-HDN appear when the mother has the blood group 0, and the fetus has the group A (subgroup A1) or the group B. Other rare incidences of AB0-incompatibility with severe course are occurred. As a whole the etiology of AB0-HDN is complex and the HDN severity is influenced by many factors. The authors have analyzed statistical data, as well as the prevalence of AB0-incompatibility and AB0-HDN in various regions of the world. Current approaches to the diagnosis of AB0-HDN are discussed in addition. By now the problems of AB0- HDN occurrence and developing of ways to overcome this disease remain relevant.

Abstract Eleven cases of hemolytic disease of the newborn are described in which the only blood group antibody in the mother's serum, incompatible with the infant's cells, was anti-A. The direct antiglobulin (Coombs) test on the infant's red cells was weakly positive in 7 cases and negative in 4 cases. In every case the mother's serum displayed immune characteristics, in particular the ability to lyse A cells. Osmotic fragility was increased in 10 out of 11 cases. This finding is contrasted with those in a series of cases of hemolytic disease of the newborn due to anti-Rh.

Fetal Erythroblastosis

La enfermedad hemolítica del recién nacido o eritroblastosis fetal es un trastorno severo que se produce por una incompatibilidad ABO o del factor Rh, lo que genera que los anticuerpos de la madre reconozcan los glóbulos rojos de la circulación fetal como agentes extraños y procedan a su posterior destrucción. En esta patología el recién nacido se caracteriza por presentar un edema en su piel o una icteria, producto de la acumulación de bilirrubina en sus fluidos corporales como la sangre; en ocasiones esta acumulación desarrolla una enfermedad neurológica conocida como Kenicterus. En la actualidad, el tratamiento se basa en una aplicación de glóbulos rojos intrauterinos en la circulación fetal para evitar la anemia y mejorar la escasez de eritrocitos fetales. Se estudiaron 41 recién nacidos a término, afectos de esta enfermedad, que fueron diagnosticados en el Hospital “San Vicente de Paúl” de Ibarra, Ecuador, durante el año 2016. El diagnóstico se apoyó en los resultados de exámenes físicos, exámenes de laboratorio y exámenes inmunohematológicos: fenotipificación de grupo ABO, prueba de Coombs directa y el título de IgG anti-A/B materno. Palabras Claves: eritroblastosis fetal, grupos sanguíneos, factor Rh, anticuerpos, eritrocitos Abstract The hemolytic disease of the newborn or fetal erythroblastosis fetalis is a severe disease which is produced by an ABO incompatibility or Rh factor that produces mother’s antibodies detect red blood cells from the fetalis circulation as a weird agents, and for this reason they destroy them. In this disease, the newborn characterizes for showing bruises in his skin and an icterus, which is produced by the accumulation of bilirubin in his body fluids such as blood; sometimes, this accumulation develops a neurological disease which is called Kenicterus. Nowadays, the treatment is based on the application of intrauterine red blood cells into the fetalis circulation to avoid anemia and improve the lack of fetalis red blood cells. We studied 41 infants at term, affected by this disease, who were diagnosed in the Hospital "San Vicente de Paul" in Ibarra, Ecuador, during the year 2016. The diagnosis was based on the results of physical exams, laboratory tests and Immunohematologic exams: ABO group phenotyping, direct Coombs test and maternal anti-A / B IgG titre.

The osmotic fragility and critical hemolytic volume were determined in red cells obtained from common Amazon fishes including the arawana (Osteoglossum bicirrhosum), the armored catfish (Pterygoplichthys), the electric eel (Electrophorus electrocus), the pirarucu (Arapaima gigas), and the lungfish (Lepidosiren paradoxa). The red cells of the pirarucu and the electric eel displayed the osmotic fragility profile remarkedly akin to human red cells, whereas the red cells of the armored catfish were considerably more resistant to hemolysis than human cells. The arawana cells exhibited a broad shoulder in the region of 120 mM to 70 mM followed by a complete hemolysis near 40 mM NaCl as in other fishes. Unexpectedly, the lungfish red cells were found to be extraordinarily resistant to hemolysis. A 15-min and a 1-h exposure of the lungfish cells to distilled water resulted in hemolysis of 55 and 80%, respectively. The critical hemolytic volume of Amazon fish red cells thus far examined was of the order of 1.83–2.03, except the pirarucu red cells which had a low value of 1.25.

Binding Curves

The binding of mercury to red blood cells was measured in terms of Hg203 uptake and desorption. The significant features of the binding are: (a) rapid achievement of equilibrium (3 to 5 minutes); (b) release of a Hg-complexing material from the red cells themselves which distorts the binding curves at low concentrations of metal (2.5 x 10-7 to 5.0 x 10-6 M); (c) prevention of binding by cysteine, glutathione, penicillamine, and EDTA but not by imidazole or histidine; (d) binding of mercury in amounts up to 7 times the reduced glutathione concentration of the cells before combination with glutathione itself; (e) binding primarily to sulfhydryl groups of hemoglobin and to a small number of stromal sulfhydryl groups, but also to other non-sulfhydryl cellular ligands after saturation of the sulfhydryl groups. Associated with the binding is inhibition of glucose uptake, induction of loss of K+, and decrease in osmotic fragility. These effects increase over the range of concentrations (1 x 10-17 to 1 x 10-15 moles of Hg/RBC) well below those that result in saturation of the cellular binding sites; above 1 x 10-15 moles/RBC, the effects decrease as the cells become saturated.

Background: The hypoxic environment stimulates the human body to increase the levels of hemoglobin (HGB) and hematocrit and the number of red blood cells. Such enhancements have individual differences, leading to a wide range of HGB in Tibetans’ whole blood (WB). Study Design: WB of male Tibetans was divided into 3 groups according to different HGB (i.e., A: >120 but ≤185 g/L, B: >185 but ≤210 g/L, and C: >210 g/L). Suspended red blood cells (SRBC) processed by collected WB and stored in standard conditions were examined aseptically on days 1, 14, 21, and 35 after storage. The routine biochemical indexes, deformability, cell morphology, and membrane proteins were tested. Results: Mean corpuscular volume, adenosine triphosphate, pH, and deformability were not different in group A vs. those in storage (p > 0.05). The increased rate of irreversible morphology of red blood cells was different among the 3 groups, but there was no difference in the percentage of red blood cells with an irreversible morphology after 35 days of storage. Group C performed better in terms of osmotic fragility and showed a lower rigid index than group A. Furthermore, SDS-PAGE revealed similar cross-linking degrees of cell membrane protein but the band 3 protein of group C seemed to experience weaker clustering than that of group A as detected by Western Blot analysis after 35 days of storage. Conclusions: There was no difference in deformability or morphological changes in the 3 groups over the 35 days of storage. High HGB levels of plateau SRBC did not accelerate the RBC change from a biconcave disc into a spherical shape and it did not cause a reduction in deformability during 35 days of preservation in bank conditions.

Group A

All 110 rabbits immunized with Group A, A-variant, and C streptococcal vaccines produced 19S anti-IgG in addition to antibodies to the streptococcal carbohydrates. 19S anti-IgG was detected by hemagglutination of rabbit red blood cells coated with rabbit anti-blood group F antibody. Antisera of 88 of these animals were also tested for 7S anti-IgG with a coprecipitation assay. This assay is based on the coprecipitation of 7S anti-IgG with complexes of streptococcal carbohydrate and anti-carbohydrate antibody. 50 of the 88 anti-Group C streptococcal antisera contained 7S anti-IgGs. In eight antisera the concentration was greater than 5 mg/ml. The data suggest a genetic influence on the occurrence of 7S anti-IgG. The eight rabbits which produced more than 5 mg/ml of 7S anti-IgG belonged to three related families. Moreover, there were families in which almost every member produced 7S anti-IgG and other families in which only 30% of the members manufactured 7S anti-IgG. The streptococcal vaccine was an especially efficient stimulus for the production of 19S anti-IgG, whereas the pneumococcal vaccine was much less effective in this respect. Furthermore, 7S anti-IgGs were not detected in antipneumococcal antisera, although the concentration of anti-capsular antibodies was similar to that of anti-carbohydrate antibodies in antistreptococcal antisera.

Rapid Replacement

The red blood cells of the human fetus differ in many major respects from the red cells of the normal adult. These differences appear admirably suited for the acquisition, transport, and release of oxygen in the low oxygen atmosphere of intrauterine existence. These same differences appear to confer a handicap to the cell in the extrauterine environment, particularly under conditions of hypoxic stress. The rapid replacement of these cells by artificial means, such as early exchange transfusion, may offer an advantage to the newborn infant in certain clinical situations.
