Immunosuppression

The symptoms vary with the specific disorder.

Persistent, recurrent infections, or severe infection by microorganisms that do not usually cause severe infection, may be clues that an immunodeficiency disorder is present. Other clues include:

• Poor response to treatment
• Delayed or incomplete recovery from illness
• The presence of certain types of cancers (such as Kaposi's sarcoma or non-Hodgkin's lymphoma)
• Certain opportunistic infections (such as pneumocystis carinii pneumonia [PCP] or recurrent fungal yeast infections)

• White blood cell count , antibody/immunoglobulin levels
• T (thymus derived) lymphocyte count
• Complement levels or other measurements of immune-response components (decreased levels)

Other tests may be indicated to confirm specific immunodeficiency disorders.
