KLINIS
Anemia : Hb ↓
may be caused by :
– loss of blood (hemorrhage);
– insufficient production of erythrocytes by the bone marrow;
– production of erythrocytes with insufficient hemoglobin, usually related to iron deficiency in the diet; or
– accelerated destruction of blood cells.
– Ex : Sickle cell anemia : The sickled erythrocyte is inflexible and fragile and has a shortened life span that leads to anemia.
It increases the blood viscosity and can damage the walls of blood vessels, promoting blood coagulation. Blood flow through the capillaries is retarded or even stopped, leading to severe O2 shortage (anoxia) in tissues.

Leukocytosis
• An increase in the number of circulating leukocytes occurs as
a normal protective reaction in a variety of pathological
conditions, especially in response to infections.
• Pathological leukocytosis : leukocyte count more than 11 x
109/1 (11. 000/mm3)
Leukopenia
the total blood leukocyte count : less than 4 x 109/1 (4000/mm3).
Granulocytopenia (neutropenia)
This is a general term used to indicate an abnormal
reduction in the numbers of circulating granulocytes
(polymorphonuclear leukocytes), commonly called
neutropenia because 40 to 75% of granulocytes are
neutrophils. A reduction in the number of circulating
granulocytes occurs when production does not keep
pace with the normal removal of cells or when the life

- Peran :
• Generation of mononuclear-phagocyte system cells in
tissues;
• phagocytosis and digestion of protozoa and virus and
senescent cells
The monocyte-macrophage system consists of the
body's complement of monocytes and macrophages.
Some macrophages are mobile whereas others are
fixed. These include:
• histiocytes in connective tissues
• microglia in the brain
• Kupffer cells in the liver
• alveolar macrophages in the lungs
• sinus-lining macrophages (reticular cells) in the spleen,
lymph nodes and thymus gland
• mesangial cells in the glomerulus of nephrons in the
kidney
• osteoclasts in bone.

CLINICAL CORRELATION
• Monocytopenia occurs with acute infections, with
stress, and after treatment with glucocorticoids.
Monocytopenia also occurs in aplastic anemia, hairy cell
leukemia, acute myeloid leukemia, and as a direct result
of myelotoxic drugs.
• Monocytosis is associated with tuberculosis,
brucellosis, subacute bacterial endocarditis, Rocky
Mountain spotted fever, malaria, and visceral
leishmaniasis (kala azar).
Monocytosis also occurs with malignancies, leukemias,
myeloproliferative syndromes, hemolytic anemias,
chronic idiopathic neutropenias, and granulomatous
diseases such as sarcoidosis, regional enteritis, and
some collagen vascular diseases.

CLINICAL CORRELATION
THROMBOCYTOPENIA
This is defined as a blood platelet count below 150 x 109/1
(150 000/mm3) but spontaneous capillary bleeding does
not usually occur unless the count falls below 30 x 109/1
(30 000/mm3).
Thrombocytopenia results from one or more of three
processes: (1) decreased bone marrow production; (2)
sequestration, usually in an enlarged spleen; and/or (3)
increased platelet destruction.
Disorders of production may be either inherited or acquired.
THROMBOCYTOSIS
Thrombocytosis is almost always due to (1) iron deficiency;
(2) inflammation, cancer, or infection (reactive
thrombocytosis); or (3) an underlying myeloproliferative
process [essential thrombocythemia or polycythemia vera
or, rarely, the 5q-myelodysplastic process
