What autoimmune diseases cause low lymphocytes?

Lymphopenia is not uncommon in several human autoimmune diseases. Reduced total lymphocyte counts are observed in rheumatoid arthritis, insulin-dependent diabetes mellitus, Crohn’s disease, systemic lupus erythematosus (SLE) and primary vasculitides.

Why do viral infections cause lymphopenia?

Cell Death. Lymphocyte death plays a critical role in lymphopenia caused by many viral infections (Table 1). Apoptosis, pyroptosis, autophagy, virus-specific CD8+ cytotoxic T lymphocyte (CTL) dependent killing and antibody-dependent cell-mediated cytotoxicity (ADCC) were reported to be involved in lymphopenia.

A low white blood cell count (leukopenia) is a decrease in disease-fighting cells (leukocytes) in your blood. Leukopenia is almost always related to a decrease in a certain type of white blood cell (neutrophil). The definition of low white blood cell count varies from one medical practice to another.
