2. Anemia is the collection of signs and
symptoms of reduced oxygen delivery to
tissues as a result of a reduction in the
number of red cells and/or reduction in
blood concentration of hemoglobin below the
level that is expected for healthy person of
same age and sex.
Dr. Monika Nema
3. The world health organization (WHO) has
defined anemia as Hb<13.0 g/dl for men and
<12g/dl for women.
Dr. Monika Nema
4. Hb ( g/dl ) Ht(%) MCV (fl)
Adult men 13-17 39-49 80-100
Adult
women
12-15 33-43 80-100
Children
6-12 yr
11.5-12.5 37-46 77-95

2m-6m 9.5-14 32-42 76-84
Dr. Monika Nema
5. Most common hematologic disorder by far
It is a clinical sign of disease
It is not a single disease by itself.
Dr. Monika Nema
7. Average volume of a single red cell.
Normal : 83-101 femtolitre
Calculated as
MCV= Packed cell volume x 10
Red cell count
Dr. Monika Nema
8. Average amount of haemoglobin in each red
cells.
Normal: 27-32 picogram.
MCH= Hemoglobin concentration x 10
Red cell count
Dr. Monika Nema
9. Represents the average concentration of
haemoglobin in a given volume of packed
cells.
Normal : 31.5-34.5 g/dl.
MCHC= Hemoglobin concentration x 100
Packed cell volume
Dr. Monika Nema
10. It is a measure of degree of variation in red
cell size(anisocytosis) in a blood sample.
Normal :
As coefficient of variation(CV)- 11.6-14 %
As Standard deviation(SD) – 39-46%
Dr. Monika Nema
14. A patient presented with fatigue, shortness
of breath, weakness, irritability, reduced
work concentration to the physician.
Doctor examined and found pallor.
He simply ordered a complete blood count.
Dr. Monika Nema
16. When the average cell size (MCV) is reduced,
the anemia is classified as MICROCYTIC
ANEMIA.
Usually associated with hypochromia
It is very common in all age groups.
Dr. Monika Nema
19. Disorders of iron metabolism
- Iron deficiency anemia.
- Anemia of chronic disorder.
Disorder of globin synthesis
- Alpha and Beta Thalassemia.
Dr. Monika Nema
20. Sideroblastic anemia
- Hereditary.
- Acquired.
- Reversible Acquired.
Lead Intoxication.
Dr. Monika Nema
23. Pica ( Abnormal eating
pattern ) is striking symptom
of iron deficiency anemia.
Dr. Monika Nema
24. Iron deficiency usually arises from chronic
blood loss.
The major cause in younger women is
menstruation.
In non menstruating women and in men, the
most common source is gastrointestinal
hemorrhage.
(esophageal varices,hiatus hernia, peptic
ulcer,gastritis,neoplasm ,hook worm
infestation)
Dr. Monika Nema
25. Inadequate dietary intake of iron
Defective absorption of iron (Achlorhydriya, Gastric
surgery, Celiac disease, Duodenal bypass, Drugs,
Tannins, Phytate, Bran)
Dr. Monika Nema
26. Increased requirements of iron
(Pregnancy, Infancy, Lactation)
Inadequate presentation to erythroid precursors
(Atransferrinemia, Atransferrin receptor antibodies)
Abnormal iron balance
(Aceruloplasminemia, Autosomal dominent
hemochromatosis due to mutation in ferroportin)
Dr. Monika Nema
27. Is an inherited autosomal recessive blood disease
which results in reduced synthesis or no synthesis of
one of the globin chains that make up hemoglobin
causing the formation of abnormal hemoglobin
molecules leading to anemia.
Thalassemia is a quantitative problem.
Dr. Monika Nema
28. Thalassemia minor patients are usually
asymptomatic. Diagnosis is made through
evaluation of positive family history.
Dr. Monika Nema
29. These are group of disorders of varying
aetiology in which marrow shows marked
dyserythropoiesis & intra mitochondrial
accumulation of Fe in erythroid
precursors
Dr. Monika Nema
30. In sideroblastic anemia, majority of patient
exhibits manifestations of iron overload.
Abnormal glucose tolerance, cardiac
arrhythmia and congestive heart failure can
occur.
Dr. Monika Nema
31. In case of Lead poisoning,
There can be occupational history of inhaling
fumes in industry.
Ingestion of lead based paint chips by
children.
Ingestion of contaminated herbs and food
supplements.
Gasoline sniffing in addicted person.
Dr. Monika Nema
32. A. Chronic inflammation
Rheumatoid arthritis
systemic lupus erythematosis
Crohn’s disease
B. Chronic infection
Tuberculosis
Urinary tract disease
HIV infection
Bacterial endocarditis
pneumonia
C. Neoplasm
Carcinoma
Lymphoma
Myeloma
Dr. Monika Nema
33. Anemia is related to decrease in release of iron
from macrophage to plasma
Reduced RBC lifespan
Inadequate erythropoietin response to anemia,
caused by effects of cytokine such IL-1, TNF on
erythropoiesis
Hepcidin released by the liver in response to
inflammation.
Hepcidin functions to regulate (inhibit) iron transport
across the gut mucosa, thereby preventing excess iron
absorption and maintaining normal iron levels within
the body. Hepcidin also inhibits transport of iron out
of macrophages (where iron is stored)
Dr. Monika Nema
34. The clinical manifestation vary widely in
anemia of chronic disease because of its
association with so many diseases.
Usually, the signs and symptoms of the
underlying disorder overshadow those of the
anemia.
Dr. Monika Nema
35. In the hands, the skin of
the palms first becomes
pale, but the creases
may retain their usual
pink color until the Hb
concentration is less
than 7 g/dl.
Is a sign of anemia.
The pallor associated with
anemia is best detected in
the mucus membrane of
mouth, the conjunctiva,
lips and the nail beds
Dr. Monika Nema
36. Site Findings
Nails Flattening, Koilonychia
Tongue Soreness, Mild papillary atrophy,
Absence of filiform papillae
Mouth Angular stomatitis
Hypopharynx Dysphagia,Esophageal varices
Stomach Achlorhydria,Gastritis
Koilonychia
Dr. Monika Nema
37. Gums in lead
poisoning.
Lead lines are shown
in gums of this patient
suffering from lead
poisoning
Dr. Monika Nema
39. Most microcytic anemia are due to deficient
hemoglobin synthesis often associated with
iron deficiency or impaired iron use.
Dr. Monika Nema
40. Erythrocytes:
If symptoms of anemia are the presenting
complain, the blood hemoglobin is usually
8 g/dl or lower.
MCV – decreased. (Microcytic)
MCH- decreased. (Hypochromic)
Anisocytosis- Important early sign . Leading
to raised Red Cell Distribution Width.
Few pencil cells, few target cells can be
seen.
Dr. Monika Nema
42. Leukocytes:
Usually normal in number.
Mild graulocytopenia is seen in long standing
cases.
Recent large volume hemorrhage leads to
Neutrophilic Leukocytosis.
Due to parasitic infestation, Eosinophilia can
be seen.
Thrombocytes:
Thrombocytosis is usually seen.
Dr. Monika Nema
44. The normal film shows little
variation in red cell size
The iron deficient cells shows
variations in size (anisocytosis) and
shape (poikilocytosis), as well as
microcytosis (low average cell size)
and hypochromia (increased central
pallor).
Dr. Monika Nema
45. Usually normocytic normochromic anemia is
seen.
Hypochromia is more common than
microcytosis.
Microcytosis in anemia of chronic disease is
usually not as striking as that commonly
associated with iron deficiency anemia.
Dr. Monika Nema
46. In iron deficiency anemia, hypochromia
follows microcytosis.
Whereas in anemia of chronic disease,
hypochromia preceeds microcytosis.
Dr. Monika Nema
49. It is a measure of amount of iron bound to
transferrin.
Shows diurnal variation
Highest in morning and lowest in evening.
Influenced by recent ingestion and
absorption of iron medication.
Normal value : 0.6-1.7 microgram/L.
Dr. Monika Nema
50. The principal source of iron for hemoglobin
production is that carried by transferrin, the
iron transport protein in plasma.
When transferrin saturation with iron is less
than 16%, RBC production rate decreases and
hypochromic,microcytic cells are
manufactured. This state is known as iron
deficient erythropoiesis.
Normal transferrin saturation is 16-50%.
Dr. Monika Nema
51. It is indirect measurement of transferrin in
terms of amount of iron it will bind.
Shows slight fluctuation.
Normal value : 2.5-4.0 microgram/L.
Dr. Monika Nema
52. Disulphide linked transmembrane protein
that facilitates entry of transferrin bound
iron into cells.
Dr. Monika Nema
53. Ferritin is chiefly intracellular iron storage
protein.
Serum ferritin is glycosylated and contains
little or no iron.
In most circumstances, Serum ferritin is
proportional to total body iron stores.
Not influenced by recent iron therapy.
Normal :
Male – 15-300 microgram/L.
Female – 15-200 microgram/L.
Dr. Monika Nema
54. Ferritin levels are the single best serum
measure of storage iron.
Serum ferritin level in patient with anemia of
chronic diseases may increase
dispropotinately relative to increase in iron
stores, probably because ferritin is an Acute
phase reactant.
This phenomenon complicates diagnosis of
Iron deficiency anemia when it co-exists with
inflammatory disease.
Dr. Monika Nema
56. Total iron binding capacity –
Increased in iron deficiency anemia
Decreased in anemia of chronic disease.
Erythrocyte sedimentation rate is found to
be elevated in anemia of chronic disease
owing to its inflammatory etiology.
Dr. Monika Nema
57. Cellularity – increased
Erythroid hyperplasia
Micronormoblastic reaction
Normoblast are smaller
Late micronormoblast demonstrates persistent
basophilia and fraying of cytoplasmic borders
indicating lack of complete hemoglobinization
Myelopoiesis – Normal
Megakaryopoiesis – Normal
Depleted bone marrow iron
Dr. Monika Nema
59. Bone marrow aspirate
