X-Linked Severe Combined Immunodeficiency

SCIDX1

The atypical X-SCID patient in the present study showed a mild clinical presentation with a TlowNK B immunophenotype. The patient has reduced T- cell subpopulations with a subdued thymic output measured by sjTRECs. [ncbi.nlm.nih.gov]

  • Poor Feeding

    The patient was referred to our hospital with liver dysfunction, respiratory distress, anal abscess, poor feeding and wasting; the patient appeared to suffer from severe and persistent infections. [ncbi.nlm.nih.gov]

  • Failure to Thrive

    Disease definition Severe combined immunodeficiency (SCID) due to gamma chain deficiency, also called SCID-X1, is a form of SCID (see this term) characterized by severe and recurrent infections, associated with diarrhea and failure to thrive. [orpha.net]

    Clinically, XSCID is characterized by failure to thrive, increased susceptibility to bacterial and viral pathogens, and a lack of palpable peripheral lymph nodes. [animalabs.com]

    Although human and canine XSCID share similar features, such as a failure to thrive, hypogammaglobulinemia, an absent T cell mitogenic response, and thymic dysplasia, near normal percentages of T cells are observed in some affected dogs, whereas XSCID [ncbi.nlm.nih.gov]

    Due to a lack of functional T cells, natural killer cells, and B lymphocytes, infants have severe and recurrent infections and exhibit a failure to thrive, rashes, diarrhea and frequent illnesses. [sema4genomics.com]

    The clinical presentation during the first year of life almost universally includes failure to thrive, oral/diaper candidiasis, recurrent infections, absent tonsils and lymph nodes, persistent infections and infections with opportunistic organisms. [genedx.com]

  • Eczema

    Physical findings : Infants and children with SCID have: • Recurrent, severe infections (respiratory, meningitis, sepsis); • Rashes that look like eczema; • Chronic diarrhea; • Oral thrush; and • Failure to thrive (FTT). [secure.ssa.gov]

    SCID Symptoms & Diagnosis Symptoms In addition to frequent and often very severe respiratory infections, other symptoms of SCID in infants include poor growth, rashes that look like eczema, chronic diarrhea and recurrent thrush in the mouth, although [aaaai.org]

    Recurrent eczema -like rashes are also a common symptom. [en.wikipedia.org]

  • Withdrawn

    FINDINGS: All patients have shown substantial improvements in clinical and immunological features, and prophylactic medication could be withdrawn in two. No serious adverse events have been recorded. [ncbi.nlm.nih.gov]

A diagnostic workup for monoclonal gammopathy in P1 (including positron emission tomography–computed tomography) was negative, and the increased IgM levels spontaneously declined as the IgG levels increased. [stm.sciencemag.org]

Rituximab treatment may have a useful role in the control of LPD associated with congenital immunodeficiency prior to HSCT. [ncbi.nlm.nih.gov]

[ edit ] Treatment for X-linked SCID can be divided into two main groups, the prophylactic treatment (i.e. preventative) and curative treatment. [22] The former attempts to manage the opportunistic infections common to SCID patients [22] and the latter [en.wikipedia.org]

Prognosis Good with bone marrow transplantation. [link.springer.com]

Prognosis Currently, there is no cure for SCID. Most untreated patients die before age two. Prevention Resources Organizations Immune Deficiency Foundation. 25 W. Chesapeake Ave., Suite 206, Towson, MD 21204. (800) 296-4433. . [medical-dictionary.thefreedictionary.com]

Vaccines, which are pathogens inserted into the body to create an immune response, can lead to death in infants with X-linked SCID. [45] Moreover, with proper treatments, such as a bone marrow transplant, the prognosis is good. [en.wikipedia.org]

Prognosis There is no cure for SCID. Nearly all untreated patients die before age two, most before one year of age. Children who are treated with bone marrow transplants have a much better prognosis. Prevention There is no known way to prevent SCID. [healthofchildren.com]

Prevention, and Complications Prognosis without intervention, death by 2 years patients 6 months of age who receive transplant have the best outcomes Complications severe infection death Please rate topic. [medbullets.com]

Etiology SCID-X1 results from a defect in the IL2RG gene encoding the common gamma chain. Genetic counseling Transmission is X-linked. The documents contained in this web site are presented for information purposes only. [orpha.net]

Over 80% of infants with severe combined immunodeficiency (SCID) of unknown genetic etiology are males, yet less than a third of these affected males have a family history of X-linked disease. [jci.org]

Two patients categorized as autosomal SCID were recently found to lack Jak3 kinase activity and had elevated percentages of B cells. 4 The remaining 14 had SCID of currently unknown etiology. [bloodjournal.org]

[…] thymic precursors in these patients, which post transplant allows for thymic seeding of very early progenitors. 8 T-B NK SCID It has been estimated that 20–30% of all SCID cases have the T-B NK phenotype with defects in RAG1 or RAG2 being the most common etiology [doi.org]

Summary Epidemiology It accounts for approximately 50% of SCID cases and is the most common form of SCID in Europe. The annual incidence varies among the populations but it is estimated at approximately 1/200,000 births. The disease occurs in males. [orpha.net]

Consequently, in the absence of a complete understanding of the pathophysiology of this adverse event, it remains a challenge to design a reliable, preclinical predictive assay to test vector transduction protocols and identify changes that can improve [doi.org]

Regardless of which X is inactivated in her somatic cells, a female will have a 50% chance of passing on the disease to any male children. [9] Pathophysiology [ edit ] Interleukins are produced by lymphocytes, among other cell types, and are released [en.wikipedia.org]

X-SCID can also arise through de novo mutations and can be prevented in females by X-inactivation. [en.wikipedia.org]

SCIDXI can be cured by bone marrow transplantation (BMT) or prevented by abortion after prenatal diagnosis. METHODS: A male fetus was diagnosed as having SCIDXI by molecular, immunophenotypic, and functional analyses. [ncbi.nlm.nih.gov]

Mutations in the IL2RG gene prevent these cells from developing and functioning normally. Without functional lymphocytes, the body is unable to fight off infections. This condition is inherited in an X-linked recessive pattern. [ghr.nlm.nih.gov]
