Adenosine deaminase severe combined immunodeficiency: when to get help

Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.

  1. 1

    Is any of this happening now?

    Call 911

    Families should keep an emergency plan and current medication list.

    New healthcare professionals should be told about the immune deficiency, previous treatments, and any special blood-product requirements.

    Other emergency signs, for anyone
    • Someone who is struggling to breathe, gasping, choking, or cannot get words out
    • Someone who has chest pain, tightness or pressure lasting more than a few minutes
    • Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
    • Someone who is unconscious, or cannot be woken
    • Someone who is bleeding heavily and it will not stop with firm pressure
    • Someone who has had a seizure that will not stop, or does not wake up afterwards
    • Someone who has lips or skin that look pale, blue, grey or blotchy
    • Someone who you believe has taken an overdose or swallowed something poisonous

    Does any of this apply?

    Follow-up continues even after immune function improves.

    The schedule is more frequent during enzyme replacement, after transplant, or after gene therapy and may become less frequent once health is stable.

    Routine follow-up may also include assessment of growth, nutrition, hearing, development, school progress, lung health, and emotional well-being.

    People who received gene therapy or a stem cell transplant may need lifelong monitoring for delayed treatment effects.

    And for anyone, someone who:

    • has noticed a lump, a mole that has changed, or unexplained weight loss

The article also says

Monitoring commonly includes blood counts, lymphocyte numbers, immune-cell function, antibody levels, ADA activity, and toxic metabolite levels.

Doctors also watch for infections, autoimmune problems, treatment effects, and changes in kidney or liver function.

Immunoglobulin replacement and preventive antimicrobial medicines may continue until testing shows that the immune system can provide adequate protection.

Vaccines are restarted only under specialist guidance.

The team may check vaccine responses with antibody testing.

A genetics professional can discuss testing for relatives and options for future pregnancies.

If a family has a known ADA variant, prenatal testing or testing of a newborn sibling can often be arranged quickly.

Every sign above is quoted from the sofidex article on Adenosine deaminase severe combined immunodeficiency. If you are not sure, err upward — it is always reasonable to be checked.
