Abstract:
We report a patient with pure red cell aplasia and type I autoimmune polyglandular syndrome who also had an expansion of suppressor T lymphocytes in the peripheral blood. Southern blotting of DNA from these cells suggest T cell receptor (TCR) gamma gene rearrangement. We confirmed true clonality of this by amplification of the gene rearrangement using the polymerase chain reaction and subsequent analysis of the product by gene cloning and DNA sequencing.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
