-- Hematocrit (Hct):Hematocrit (Hct): is the proportion, by volume, of the blood occupied is the proportion, by volume, of the blood occupied
by red blood cells. The hematocrit (Hct) is by red blood cells. The hematocrit (Hct) is expressed as a percentage, normal levels are :expressed as a percentage, normal levels are :
0.4 - 0.54 in Adult male & 0.37 - 0.47 in Adult female0.4 - 0.54 in Adult male & 0.37 - 0.47 in Adult femaleFor example, a hematocrit of 25% means that there For example, a hematocrit of 25% means that there

It is diminished in microcytic anemias, and It is diminished in microcytic anemias, and increased in macrocytic anemias. It is calculated by increased in macrocytic anemias. It is calculated by dividing the total mass of hemoglobin by the RBC dividing the total mass of hemoglobin by the RBC count :-count :-

It is diminished It is diminished ("hypochromic")("hypochromic") in microcytic anemias, and normal in microcytic anemias, and normal ("normochromic")("normochromic") in macrocytic anemias (due to larger cell size, in macrocytic anemias (due to larger cell size, though the hemoglobin amount or MCH is high, the though the hemoglobin amount or MCH is high, the concentration remains normal).concentration remains normal).
It is calculated by dividing the hemoglobin by the hematocrit: It is calculated by dividing the hemoglobin by the hematocrit:

Multiple Multiple myelomamyeloma
MyelomaMyeloma In myeloma there is a clonal proliferation of
plasma cells and the clinical manifestations of disease "= are -Mated to substances secreted by the plasma cells as much as to the effects of marrow infil tration. Clonality (all diseased cells originating from one parent plasma cell) may be confirmed by: the presence of a paraprotein (monoclonal) band on
serum electrophoresis, or by Immunopheno typing the increased numbers of
plasma cells in the bone marrow, and finding,. that they all express either kappa or lambda light chains rather than a mixture of the two.
Paraprotein sub-typesParaprotein sub-typesThe normal immunoglobulin
concentrations in serum parallel the relative frequency of the three main sub-classes of myeloma paraprotein. Hence, IgG is the most common form of myeloma, followed by IgA, with IgM being the least common type.
Plasma hyperviscosity syndrome may Plasma hyperviscosity syndrome may be found be found This: consists of confusion, capillary bleeding, This: consists of confusion, capillary bleeding, oedema and renal impairment. The incidence of oedema and renal impairment. The incidence of hyperviscosity syndrome relates to the size of hyperviscosity syndrome relates to the size of the immunoglobulin molecule as well as its the immunoglobulin molecule as well as its concentration. As IgM is the largest molecule concentration. As IgM is the largest molecule (750, 000 daltons) this syndrome is seen (750, 000 daltons) this syndrome is seen relalatively frequently in IgM myeloma, less relalatively frequently in IgM myeloma, less frequently in IgA myeloma and rarely in IgG frequently in IgA myeloma and rarely in IgG myeloma:. Transfusion should be avoided in myeloma:. Transfusion should be avoided in patients with plasma hyperviscosity syndrome, patients with plasma hyperviscosity syndrome, as it willas it will,, cause a big increase in whole blood cause a big increase in whole blood viscosity.viscosity.
Cryoglobulin: rarely, the paraprotein Cryoglobulin: rarely, the paraprotein
may be a cryoglobulin, so that the may be a cryoglobulin, so that the

Bence-Jones Bence-Jones proteinprotein Sometimes, the malignant plasma cells
are so defective that they cannot make a complete immunoglobulin molecule and are only able to make light chains. The latter are small enough to he filtered within the glomerulus and to appear in the urine as Bence-Jones proteinurias. They may obstruct the renal tubules and contribute to the renal failure which is often found in myeloma.
Role Role of of cytokines cytokines in myelomain myeloma Osteoclast-activating factors Osteoclast-activating factors
stimulate the normal osteoclasts stimulate the normal osteoclasts to dissolve bone and lead to bone to dissolve bone and lead to bone pain, hypercalcaemia and pain, hypercalcaemia and pathological fractures in myeloma. pathological fractures in myeloma. In other myeloma cases, IL -6 may In other myeloma cases, IL -6 may be produced in excess by bone be produced in excess by bone marrow stromal cells infected with marrow stromal cells infected with human herpes virus (HHVB).human herpes virus (HHVB).
Treatment of myeloma Inn younger patients, most centers are moving
away from single-agent melphalan therapy towards continuous low-dose combination chemotherapy such as VAD (Vincristine, Adriamycin and Dexamethasone) or ZDex (oral idarubicin and dexamethasone). Malignant cells are most sensitive to the action of chemotherapy when they are dividing; as plasma cells divide relatively infrequently, it is necessary to administer the chemotherapy over several days in order to maximise the chances of treatingg dividing cells.
Thalidomide has a proven role in myeloma treatment although its mechanism of action remains uncertain. It is likely to inhibit cytokine release, but an anti-angiogenesis activity has not been ruled out.
Bisphosphonates, such as monthly intravenous pamidronate, have an important role in the prevention off pathological fractures and in the treatment of myeloma-associated hypercalcaemia.
Monoclonal gammopathy of undetermined significance (MGUS)
A common clinical problem is the differentiation between myeloma and MGUS (benign monoclonal gammopathy) in patients found to have a paraprotein. Ten per cent of patients with MGUS develop myeloma at 5 years, and 50% at 15 years. It is probable that most patients would eventually develop myeloma but many die of other causes before this occurs.
