Newborn Screening for Severe Combined Immunodeficiency: Lessons Learned from Screening and Follow-Up of the Preterm Newborn Population
A Gaviglio et al, IJNS, December 2023 (Posted: Dec 18, 2023 8AM)

From the abstract: " Newborn screening (NBS) for Severe Combined Immunodeficiency (SCID) by measurement of T-cell receptor excision circles (TRECs) successfully identifies newborns with SCID and severe T-cell lymphopenia, as intended. At the same time, NBS programs face the challenge of false positive results, with a disproportionately high number in the premature newborn population. This study evaluates TREC values and SCID screening outcomes in premature newborns and elucidates evidence-based SCID screening practices that reduce unnecessary follow-up activities in this population."

Screening newborns for deadly immune disorder saves lives
NIH, July 2023 (Posted: Jul 14, 2023 1PM)

Newborn screening for severe combined immunodeficiency (SCID) led to prompt treatment before life-threatening infections occurred, boosting survival of children with the disorder. The findings could encourage more widespread screening of newborns around the world for this disease.

Implementation of Newborn Screening for Conditions in the United States First Recommended during 2010–2018
S Singh et al, IJNS, April 2023 (Posted: Apr 09, 2023 8AM)

During 2010–2022, seven conditions were added to the RUSP: severe combined immunodeficiency (SCID) (2010), critical congenital heart disease (CCHD) (2011), glycogen storage disease, type II (Pompe) (2015), mucopolysaccharidosis, type I (MPS I) (2016), X-linked adrenoleukodystrophy (X-ALD) (2016), spinal muscular atrophy (SMA) (2018), and mucopolysaccharidosis, type II (MPS II) (2022). The adoption of SCID and CCHD newborn screening by programs in all 50 states and three territories (Washington, D.C.; Guam; and Puerto Rico) took 8.6 and 6.8 years, respectively.

Gene Therapy for Artemis-Deficient SCID
SY Pai, NEJM, December 22, 2022 (Posted: Dec 22, 2022 8AM)

Infants with severe combined immunodeficiency (SCID), a disease characterized by a failure of T-cell development, die of opportunistic infection unless treated. Standard allogeneic hematopoietic-cell transplantation has limitations due to immunologic differences between the patient and the donor. A recent study used an integrating viral vector to bring about gene “addition”. Gene addition takes advantage of the natural properties of certain types of viruses, including the lentiviruses, to integrate into the patient’s genome in a semirandom fashion.

Modelling the Cost-Effectiveness and Budget Impact of a Newborn Screening Program for Spinal Muscular Atrophy and Severe Combined Immunodeficiency
STF Shih et al, IJNS, July 20, 2022 (Posted: Jul 21, 2022 7AM)

Over a 60-year time horizon, screening every newborn in the population and treating diagnosed SCID by early hematopoietic stem cell transplantation and SMA by gene therapy, would result in 95 QALYs gained per 100,000 newborns, and result in cost savings of USD 8.6 million. Sensitivity analysis indicates 97% of simulated results are considered cost-effective against commonly used willingness-to-pay thresholds. The introduction of combined NBS for SCID and SMA is good value for money from the long-term clinical and economic perspectives, representing a cost saving to governments in the long-term, as well as improving and saving lives

Gene therapy helps children with immunodeficiency
O'Leary, Nature Medicine, June 10, 2021 (Posted: Jun 11, 2021 7AM)

Adenosine deaminase (ADA) deficiency is a rare, inherited disorder that leads to potentially life-threatening severe combined immunodeficiency (ADA-SCID). Enzyme-replacement therapy provides only limited benefit and patients ultimately require a stem-cell transplant. A lentivirus-based treatment restores immune function with minimal side effects in children with adenosine deaminase deficiency.

Newborn screening for severe combined immunodeficiency: clinical and cost-effectiveness approaches.
Boyarchuk Oksana et al. Polski merkuriusz lekarski : organ Polskiego Towarzystwa Lekarskiego 2021 49(289) 80-83 (Posted: Mar 16, 2021 10AM)

Newborn screening for SCID with T-cell receptor excision circle (TREC) and kappa-deleting recombination excision circle (KREC) assay for the identification of T- and B-lymphopenia has been implemented in a number of highly developed countries of the world. A number of studies proved the clinical and cost-effectiveness of screening for SCID by using TREC assay. However, both clinical benefits and economic costs for screening may vary depending on country and continent.

David Vetter was ‘the boy in the bubble.’ His short life provided insights into how the rare disorder SCID works.
E Blakemore, Washington Post, January 2020 (Posted: Feb 04, 2020 9AM)

David’s short life also provided insights into how SCID works. Better bone marrow screening now means more transplants are successful. According to the Immune Deficiency Foundation, 91 percent of infants who are diagnosed early and given transplants by age 3½ months survive

Also known as Lymphopenia Lymphocytopenia (LIM-fo-si-to-PE-ne-ah) is a disorder in which your blood doesn&rsquo;t have enough white blood cells called lymphocytes (LIM-fo-sites).</p><p>These cells are made in the bone marrow along with other kinds of blood cells. Lymphocytes help protect your body from infection. Low numbers of lymphocytes can raise your risk of infection. Lymphocytopenia also is called lymphopenia. Overview About 20 to 40 percent of all white blood cells are lymphocytes. A normal lymphocyte count for adults usually is between 1,000 and 4,800 lymphocytes per microliter of blood. For children, a normal lymphocyte count usually is between 3,000 and 9,500 lymphocytes per microliter of blood. The term "lymphocytopenia" refers to a count of less than 1,000 lymphocytes per microliter of blood in adults, or less than 3,000 lymphocytes per microliter of blood in children. The three types of lymphocytes are B lymphocytes, T lymphocytes, and natural killer cells. All of these cells help protect the body from infection. Most people who have lymphocytopenia have low numbers of T lymphocytes. Sometimes they also have low numbers of the other types of lymphocytes. Certain factors can cause a low lymphocyte count, such as: The body doesn't make enough lymphocytes. The body makes enough lymphocytes, but they're destroyed. The lymphocytes get trapped in the spleen or lymph nodes. Lymphocytes normally pass through these organs into the blood. A combination of the above factors. Many diseases, conditions, and factors can cause the above problems that lead to lymphocytopenia. These causes can be acquired or inherited. "Acquired" means you aren't born with the condition, but you develop it. One of the most common acquired causes of lymphocytopenia is AIDS. "Inherited" means your parents passed the gene for the condition on to you. Inherited causes include DiGeorge anomaly, Wiskott-Aldrich syndrome, severe combined immunodeficiency syndrome, and ataxia-telangiectasia. These inherited conditions are rare. Outlook Lymphocytopenia can range from mild to severe. The condition alone may not cause any signs, symptoms, or serious problems. How long lymphocytopenia lasts depends on its cause. The treatment for this condition depends on its cause and severity. Mild lymphocytopenia may not require treatment. If an underlying condition is successfully treated, lymphocytopenia will likely improve. If lymphocytopenia causes serious infections, you may need medicines or other treatments.
