Severe Combined Immunodeficiency (SCID) is a potentially fatal primary immunodeficiency. This condition is generally considered to be the most serious of the primary immunodeficiencies. Today, early identification of SCID can make possible life-saving interventions. Join the Immune Deficiency Foundation as we speak with Nicole Locastro, a mother of a child diagnosed with SCID through newborn screening. Nicole offers us some thoughtful insights into the family experience and some strategies her family employed along the way.

There is a recent misconception circulating that COVID-19 causes immunodeficiency. The TL;DR: this is not the case.

Immunodeficiency occurs when one (or both) arms of the adaptive immune system are not functioning properly. This means that individuals become susceptible for a broad array of opportunistic illnesses. These include infections with microorganisms that would normally not cause disease in most healthy individuals.

These include:

Pneumocystis pneumonia: serious respiratory illness caused by fungal infection by the pathogen Pneumocystis jirovecii

Tuberculosis: caused by the bacterium Mycobacterium tuberculosis. Typically very rare, infection risk increases if someone’s immune system is not functioning properly.

Coccidioidomycosis: also called valley fever, this is another infection with a fungus found in the soil.

Cryptosporidiosis: a parasitic infection that can cause diarrhea and other severe GI symptoms

These types of illnesses are not occurring after recovery from COVID-19. T cells are not being “wiped out” after COVID-19. Yes, there is some evidence that some individuals have temporary immune system changes or perturbations after infection with SARS-CoV-2, but that is not the same as immunodeficiency, and is also not unique to this virus. More on this topic soon!

Winter respiratory illnesses such as RSV and influenza are not opportunistic infections. We’ve chatted about some reasons why there is increased infection activity previously, so check that out too.

Please be careful who you consume information from – misleading info is everywhere.

Severe combined immunodeficiency (SCID) represents a constellation of genetically distinct syndromes with the common feature of defects in both humoral and cell-mediated immune responses. Affected infants are susceptible to severe recurrent infections by a wide array of pathogens, including bacteria, viruses, fungi, and protozoans; opportunistic infections by Candida, Pneumocystis, CMV, and Pseudomonas also cause serious (and occasionally lethal) disease.

Wiskott-Aldrich syndrome is an X-linked recessive disease characterized by thrombocytopenia, eczema, and a marked vulnerability to recurrent infection, ending in early death; the only treatment is bone marrow transplantation.

“Examples of antibody deficiencies include when you have absent B cells such as X-linked agammaglobulinemia, impaired b cells such as common variable immune deficiency (CVID) or have selective antibody deficiency with abnormalities in shape and structure such as IgA deficiency.

For suspected antibody immunodeficiency disease important to measure immunoglobulins: Serum IgA, IgM and IgG subclasses and lymphocytes count and subsets. Remember to exclude secondary cause of low Immunoglobulins”
