Massive intravascular hemolysis without serum haptoglobin depletion. 1985

M A Baumann, and G A Hanson, and K D Reed, and R M Hansen

Hyperplasia of marrow histiocytes with extensive hemophagocytosis was found in a patient with cytomegalovirus infection. He experienced massive intravascular hemolysis, but, unexpectedly, no depression of the serum haptoglobin level was found by either single radial immunodiffusion or rate nephelometry. The unexpectedly high haptoglobin value may have been the result of "blockade" of the monocyte-macrophage system, with resultant failure to clear haptoglobin-hemoglobin complex rapidly from the circulation. Use of the techniques described for the indirect estimation of unbound serum haptoglobin alone should avoid confusing results in similar clinical circumstances.

UI	MeSH Term	Description	Entries
D006965	Hyperplasia	An increase in the number of cells in a tissue or organ without tumor formation. It differs from HYPERTROPHY, which is an increase in bulk without an increase in the number of cells.	Hyperplasias
D008297	Male		Males
D010587	Phagocytosis	The engulfing and degradation of microorganisms; other cells that are dead, dying, or pathogenic; and foreign particles by phagocytic cells (PHAGOCYTES).	Phagocytoses
D001853	Bone Marrow	The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

D003586	Cytomegalovirus Infections	Infection with CYTOMEGALOVIRUS, characterized by enlarged cells bearing intranuclear inclusions. Infection may be in almost any organ, but the salivary glands are the most common site in children, as are the lungs in adults.

D006242	Haptoglobins	Plasma glycoproteins that form a stable complex with hemoglobin to aid the recycling of heme iron. They are encoded in man by a gene on the short arm of chromosome 16.	Haptoglobin
D006454	Hemoglobins	The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates. The number of globin subunits in the hemoglobin quaternary structure differs between species. Structures range from monomeric to a variety of multimeric arrangements.

D006461	Hemolysis	The destruction of ERYTHROCYTES by many different causal agents such as antibodies, bacteria, chemicals, temperature, and changes in tonicity.
