If you are experiencing recurring infections, it could be the result of primary immunodeficiency disease (PIDD). When part of the immune system is either absent or not functioning properly, due to hereditary or genetic reasons, it’s called PIDD. If the immune system is damaged due to other factors (chemotherapy, HIV, malnutrition, etc.), the condition is called secondary immunodeficiency disease.
Important signs and symptoms that may indicate a PIDD include:
● Recurrent, unusual, or difficult to treat infections● Poor growth or loss of weight● Recurrent pneumonia, ear infections, or sinusitis● Multiple courses of antibiotics or IV antibiotics necessary to clear infections● Recurrent deep abscesses of the organs or skin● A family history of PIDD● Swollen lymph glands or an enlarged spleen● Autoimmune disease
