In norm The number of erythrocytes: in female - 3,9-4,7·1012/l in male - 4,5-5,0·1012/l Hemoglobin in female g/l in male g/l Color index(CI) - 0,85-1,15 Globular value = 3 x Hb / the first 3 figures of erythrocytes. Reticulocytes %, 0,5-2%0
3
Anemia -is a syndrome or disease which is characterized by the decrease of erythrocytes and hemoglobin amount in the unite of blood volume and accompanied by qualitative changes of erythrocyte.
4
Classification of anemia
I. According to etiology: Hereditary and acquired II. According to pathogenesis : Diserythropoietic Hemolytic Posthemorragic
5
IІІ. According to type of hematopoesis:
1. with erythroblastic 2. with megaloblastic ІV. According to color index (globular value): 1. normochromic 2. hypochromic 3. hyperchromic
6
Color index(CI) - 0,85-1,15 Globular value = 3 x Hb (g/l) / the first 3 figures of erythrocytes. ІV. According to color index (globular value): 1. normochromic 2. hypochromic 3. hyperchromic
7
V. According to ability of bone marrow to regeneration:
regenerative hyperregenerative hyporegenerative aregenerative
8
Qualitative (degenerative) changes of red blood cell
- poikilocytosis - different shape of erythrocytes; - anisocytosis different size of erythrocytes; - anisochromia - different saturation of red blood cells by hemoglobin
9
- pathological inclusions in the erythrocytes :
Cabot rings Jolly bodies
11
Relative (in case of plasma volume decrease).
Erythrocytosis – it is increase of the erythrocytes number in one unit of blood volume Absolute : 1). Primary 2). Secondary Relative (in case of plasma volume decrease).
12
Vaquez disease Erythremia (true polycythemia) - chronic leukemia with the defect of cells of precursor of mielopoesis with unlimited proliferation hematopoetic cells. Blood picture: Hemoglobin (over 180g/l) Erythrocyte (over 6x1012/l) Platelets (over 400x109/l) Leukocyte (over 10x109/l) Hematocrit ↑
14
Anemia -is a syndrome or disease which is characterized by the decrease of erythrocytes and hemoglobin amount in the unite of blood volume and accompanied by qualitative changes of erythrocyte.
17
Iron-deficiency anemia
Reasons: blood loss chonic low initial level of Fe high requirement of Fe alimentary disorder of absorption transferrin insufficiency
18
Iron-deficiency anemia
Blood picture : Erythrocyte number ↓ Reticulocyte number ↓ Hemoglobin amount ↓ Color index (globular value) ↓ Smear: microcytes, anulocytes In the serum : the amount of iron is reduced (in norm: 12,5 - 30,4 mcmol/l).

PALENESS OF SKIN BRITTLE HAIR CRACKED LIPS BRITTLE NAILS
23
PRINCIPLES OF TREATMENT :
!!! Before taking of iron supplements to determine the Fe level in the blood
24
Etiotropic treatment: balanced diet
25
Pathogenetic treatment :
Oral and parenteral Iron therapy: Iron supplements intake (Fe bivalent!) in combination with vitamin C (vitamin C improves absorption of Fe in the blood) Replacement therapy : According to indications – red cell transfusion.
26
IRON REFRACTORY is anemia which arises up as a result of the violation of iron including into hemoglobin, at the activity decrease or absence of enzymes which are needed for the hemoglobin synthesis (protoporphyrin ІX deficiency) Reasons: 1. Hereditary 2. Lead poisoning, alcoholism.
27
Iron-refractory anemia
Blood picture : - Hemoglobin amount ↓ - Erythrocyte number ↓ - Color index (globular value) ↓ Sideroblasts ↑ In the blood serum the number of iron increases!!!!. In marrow the sideroblasts number increases.
28
PRINCIPLES OF THERAPY:
Normalization of porphyrin metabolism (vitamins B6) Removal of Fe from the tissues
29
insufficient intake with food pathology of the stomach
В12-deficiency anemia Reasons: insufficient intake with food pathology of the stomach pathology of the intestine transcobalamin deficiency hepatitis pregnancy
31
В12-deficiency anemia Erythrocyte number ↓ Hemoglobin amount ↓
Blood picture Erythrocyte number ↓ Hemoglobin amount ↓ Color index (globular value) ↑ ↑ Leukopenia, hypersegmentation of neutrophils Thrombocytopenia In the smear of blood: megalocytes, megaloblasts; Jolly's bodies; Cabot's rings.
33
Glossitis – inflammation with depapillation of the tongue
dorsal surface Atrophic gastritis Funicular myelosis Pancytopenia
34
PRINCIPLES OF THERAPY :
Etiotropic treatment : balanced diet Pathogenetic treatment : cyanocobalamin and folic acid
35
Hypoplastic (aplastic) - anemia which affects bone marrow erythrocyte sprout on the background of a deep bone marrow suppression and sharply reduced production of red blood cells and granulocytes and platelets (pancytopenia).
36
Causes: Ionizing radiation, infectious, chemicals - drugs: [sulfonamides, levomycetin, cytostatics, anti-TB drugs], benzol and its derivatives, pesticides; Blood Picture: Number of Hb ↓ Erythrocyte number ↓ Color index - normochromic Pancytopenia (↓ leukocytes, platelets).
37
Hemolytic is anemia which arises up as a result of increased hemolysis when destruction of erythrocytes prevails above their production. Classification : І. Hereditary – Membranopathy Haemoglobinopathy Enzymopathy ІІ. Acquired
38
Classification of hemolytic anemia
І. Hereditary Membranopathy Haemoglobinopathy Enzymopathy ІІ. Acquired
39
Classification: After the mechanism of hemolysis hemolytic anemias are divided into: anemias with intravascular hemolysis; anemias with intracellular hemolysis.
40
Reasons and mechanisms of the intracellular hemolysis:
inherited or acquired defect of erythrocytes; antibody-dependent [cell- mediated];
41
microspherocytosis or Minkowsky-Shauffard disease [hereditary spherocytosis].
Blood picture : 1. The number of hemoglobin decreases. 2. The number of erythrocytes is decreases. 3. CI is normal - normochromic anemia. 4. The reticulocytes number increases - hyperregenerative anemia. 5. Decrease of erythrocytes osmotic resistance takes place. 6. Increase mean concentration of hemoglobin in the red blood cell (МСНС) more than 36%. 6. The number of unconjugated [indirect] bilirubin increases.
43
Enzymopathy-deficiency of the enzyme Gl-6-FDG
Blood picture : 1. Erythrocyte number ↓ 2. Hemoglobin amount ↓ 3. Color index (globular value) – normochromic. 4. Reticulocyte number ↑ 5. Erythrocytes osmotic resistance ↓ 6. Indirect bilirubin ↑
44
Hemoglobinopathys are the anemias related to the violation of hemoglobin synthesis.
Types of hemoglobinopathys : The 1st – is the hemoglobin chains synthesis violations; The 2nd – is the hemoglobin chains structure violations.
45
α-thalassemia Blood picture : 1. Erythrocyte number ↓ ↓
Hemoglobinopathy α-thalassemia Blood picture : 1. Erythrocyte number ↓ ↓ 2. Hemoglobin amount ↓ 3. Color index ↓. 4. Reticulocyte number ↑ 5. Erythrocytes osmotic resistance ↓ 6. Indirect bilirubin ↑ 7. Target erythrocytes (codocytes)
48
Sickle-cell anemia Blood picture : Erythrocyte number ↓
Hemoglobin amount ↓ Color index (globular value) – normochromic Indirect bilirubin ↑ Smear - Sickle-cell
