Outcome : The student will know :• -The definition of anemia .• -The classification of anemias .• -The diagnosis of anemias

Course title : Hematology (1)Course code :MLHE-201 Supervisor : Prof Dr. Magda Sultan 14/11/2013.

Introduction ToAnaemias

2013

Definition of anaemiaReduction below normal in the concentration of Hb or RBCs ( according to age and sex )

Adult male: Hb 13.5-17.5 g/dl RBCs 4.5 – 6.00 Adult female : Hb 12.0- 16.0 g/dl RBCs 3.80-5.00

The approach to the diagnosis :1-Detection of the anaemia ( by accurate

measurements of the patient values)2-Type of the anaemia .3-Investigations of the cause of anaemia

• Laboratory evaluation of anaemia : 1-Study of the blood :• -Complete blood count ( Hb, Ht, RBCs, Red cell

indices , WBC and platelets )• -Examination of stained blood film .• -Reticulocyte count .

2- Other laboratory tests : -Serum iron ,TIBC, serum ferritin , B12, folate,

Coomb's test , osmotic fragility , G6PD ,Hb electophoresis ,ESR , liver and kidney functions tests , thyroid tests ,bone marrow examination.

• Classification of anaemias Morphologic classification :

Blood film + Red cell indices

• 1-Microcytic Hypochromic anaemia : MCV reduced and MCH reduced • 2-Normocytic Normochromic anaemia : MCV normal and MCH normal • 3-Macrocytic anaemia : MCV increased

• Microcytic Hypochromic anaemia Causes : 1-Iron deficiency anaemia . 2-Thalathemias. 3-Haemoglobinopathies. 4-Chronic disorders .

• Investigations : 1-Serum iron . 2-TIBC . 3-Serum ferritin . 4-Haemoglobin electrophoresis .

• Nomocytic Normochromic anaemia Causes : 1-Haemolytic anaemia . 2-Post haemorrhagic anaemia . 3-Liver disease . 4- Renal disease . 5-Endocrine disorders . 6-Hypoplastic anaemia . 7-Bone marrow infiltration .

• Investigations : 1-Reticulocyte count . 2-Coomb's test .3-Hb electrophoresis . 4-Osmotic fragility .5-G6PD 6- Endocrine tests 7-Liver and renal function tests.8-Bone marrow aspiration and biopsy

• Macrocytic anaemia Types : • 1-Megaloblastic 2- Non Megaloblastic Causes :1-Vitamin B12 deficiency . 2-Folate deficiency .3-Haemolytic anaemia . 4-Haemorrhage .5-Alcohol . 6-Liver and thyroid diseases.7-Hypoplastic bone marrow.

• Investigations : 1-Serum B12

2-Folate assay 3-Bone marrow examination 4-Reticulocyte count 5-Tests for liver and thyroid disorders .
