Transient regression in lymphocyte count in B-cell chronic lymphocytic leukemia after viral infection
1Division of Clinical Hematology and Immunology, Kumamoto City Hospital, Japan.
Abstract:
Transient regression in the lymphocyte count of a patient with B-cell chronic lymphocytic leukemia (B-CLL) after viral infection is reported. A similar event occurred under natural interferon-alpha (IFN-alpha) treatment. It was confirmed that the event was not caused by a direct cytotoxic effect of IFN-alpha by analyzing the DNA fragmentation to estimate apoptotic and necrotic cell death before and after the administration of IFN-alpha. The study also suggested that the event was not caused by a cytostatic effect of IFN-alpha.

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...
