secondary immunodeficiency

sec·on·dar·y im·mu·no·de·fi·cien·cy

immunodeficiency with no evident defect in the lymphoid tissues, but rather hypercatabolism or loss of immunoglobulins such as occurs in familial idiopathic hypercatabolic hypoproteinemia, protein-losing enteropathy, nephrotic syndrome, uremia, malnutrition, infection, diabetes, or malignancy.

secondary immunodeficiency

a loss of immunity caused by a disease process or toxic effect of medication rather than by a failure or defect in T or B lymphocytes.

Mycobacterial, fungal and other opportunistic infections force the clinician to rule out a large list of conditions associated with secondary immunodeficiency as infectious agents (HIV, Herpesvirus, HTLV), drugs (steroids, immunosuppressants, biologics, chemotherapy), metabolic diseases (diabetes, renal failure, cirrhosis), malignancies (leukemia, lymphomas and solid tumors) and environmental conditions (radiation, heavy metals) (2) but even adult patients can have late onset primary genetic immunodeficiency disorders as chronic granulomatous disease, X-linked agammaglobulinemia, interleukin-12 receptor deficiency or interferongamma (IFN-?
Idiopathic CD4 lymphocytopenia for the first time was described in the year 1992 by the CDC, as cases which demonstrated depressed (<300/cumm) numbers and proportions of CD4 count (<20% of total T cells), on at least two consecutive occasions, with no laboratory evidence of HIV-1 and HIV-2 infection, HTLV-1 or HTLV-2 infection, and the absence of any primary or secondary immunodeficiency disease, or treatment associated with depressed level of CD4 levels.
