Primary Immunodeficiency

Primary Immunodeficiency refers to a group of over 400 rare, genetically inherited disorders in which part of the immune system is missing or functions improperly, leaving affected individuals more vulnerable to infections, autoimmune disease, and certain cancers. Unlike secondary immunodeficiencies caused by external factors like HIV or medications, these conditions result from inborn errors in immune system genes present from birth. Severity ranges widely from mild forms that cause occasional infections to severe combined immunodeficiencies that are life-threatening in infancy without treatment. Early diagnosis and specialized care significantly improve outcomes and quality of life.

The most common symptoms include: Frequent or unusually severe infections; infections that don't respond well to standard antibiotic treatment; recurrent pneumonia or sinus infections; poor growth in infants and children. Early recognition is key to prompt diagnosis and effective treatment.

No, Primary Immunodeficiency is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

Treatment options include: Treatment depends on the specific defect and may include regular immunoglobulin replacement therapy to provide antibodies the body cannot produce; prophylactic antibiotics to prevent infections; and in severe cases. Treatment should always be guided by a qualified Allergy & Immunology specialist. Do not self-medicate.

While Primary Immunodeficiency cannot always be fully prevented, several measures can reduce risk: No known prevention due to genetic basis; but early diagnosis through newborn screening and genetic testing in at-risk families; prompt treatment of infections.

Seek immediate medical attention if you experience symptoms of Primary Immunodeficiency. This is a serious condition — go to the emergency room or call 112 if symptoms are severe or rapidly worsening.
