- 1,2,3
- 1,2,3,4
Haemolytic disease of the newborn is a consequence of:
- Increased HbF levels
- Increased number of enzyme deficient erythrocytes
- Increaed levels of maternal Rh antibodies in the blood of Rh-negative fetus
- Incompatible (ABO) haemotransfusion to the mother during delivery
- Spontaneous activation of cryogenic antibodies during delivery
Haemoglobinopathies are hereditary diseases, resulting from:
- Enzyme defect in the glicolytic cycle
- Glucose-6-phosphatedehydrogenase deficiency in erythrocytes
- Reduced gluthatione deficiency in erythrocytes
- Genetically determined defect in the globin synthesis of haemoglobin
- Genetically determined defect in the protoporphyrin ring synthesis
Microshperocytic anaemia of Minkowski-Chauffard is a result of:
- Defect in the synthesis of haemoglobin beta chains
- Genetic defect in the protein structure of the erythrocyte membrane
- Inactivated glucose-6-phosphate-dehydrogenase and presence of cryogenic autoantibodies
- Hexokinase inactivation
- Methaemoglobin reductase deficiency
Glucose-6-phosphate-dehydrogenase deficiency in erythrocytes leads to:
- Glycolytic chain disturbance with consequent energetic deficiency

Cooley’s anemia (Thalassemia major) is a result of:
