Immunoproliferative disorders Flashcards
what are monoclonal gamopathies
conditions characterised by abmormal proliferation of single clone of plasma cells = production of M protein
3 monoclonal gammopathies which are immunoproliferative disorders (abnormal proliferation of lymphoid/plasma cells)
multiple myeloma
waldenstrom’s macroglobulinemia
monoclonal gammopathy of undetermined significance (MGUS)
heavy chain disease
what is MGUS
premalignant condition - presence of m protein in blood without symptoms or organ damage
what is multiple myeloma characterised by
abnormal proliferation of plasma cells in bone marrow = m protein production
what in the bone is common in MM
osteolytic bone lesions (bone breakdown)
what is calcium like in MM
high (hypercalcaemia) due to bone loss
What antibodies are overproduced by B lymphocytes in waldenstrom’s macroglobulinemia leading to blood thickening and damage to kidneys
IgM
what is alpha heavy chain disease characterised by
overproduction of abnormal alpha heavy chains by plasma cells which accumulate in small intestine
