Immune system tissues (especially lymphoid tissue such as the thymus) shrink, and the number and activity of white blood cells drop. People with diabetes are also at higher risk for certain infections.Īs you get older, the immune system becomes less effective. People who have had their spleen removed have an acquired immunodeficiency, and are at higher risk for infection by certain bacteria that the spleen would normally help fight. Many cancers may also cause immunodeficiency.

Drugs used to treat health problems such as rheumatoid arthritis, inflammatory bowel disease, and certain skin conditionsĪcquired immunodeficiency may be a complication of diseases such as HIV/AIDS and malnutrition (especially if the person does not eat enough protein).People are said to be immunosuppressed when they have an immunodeficiency disorder due to medicines that weaken the immune system. It may be deadly within the first year of life if it isn't treated early. Inherited combined immunodeficiency affects both T cells and B cells. Inherited immunodeficiency disorders that affect T cells may cause repeated Candida (yeast) infections. Agammaglobulinemia, which results in severe infections early in life, and is often deadly.Hypogammaglobulinemia, which usually leads to respiratory and gastrointestinal infections.Inherited immunodeficiency disorders that affect B cells include: Most often, these conditions occur when special white blood cells called T or B lymphocytes (or both) do not function normally or your body does not produce enough antibodies. But ultimately the treatment is a significant advancement in treating Artemis-deficient SCID, he says.Immunodeficiency disorders may affect any part of the immune system. The study may have also missed other potential side effects because of its small sample size, says Vincent Bonagura at the Feinstein Institutes for Medical Research in New York. There were no serious side effects from the treatment itself, but researchers plan to follow the children for longer to be certain, says Cowan. The next stage of the research is to conduct trials with more children. With time, the other participants should also develop fully functional immune systems, says Jennifer Puck, also at the University of California, San Francisco. Of the six infants who received the therapy two or more years ago, five now have fully functioning immune systems. This made space for the corrected stem cells, which were infused back into them using an IV.įollow-up blood tests found that all the children produced T cells and B cells between six and 16 weeks after treatment. The children then underwent a low dose of chemotherapy to kill cells in their bone marrow. The researchers extracted stem cells from the bone marrow of 10 infants with the condition and inserted corrected genetic information into the cells. Without Artemis, the body cannot produce important immune cells called T cells and B cells. This subtype of SCID is caused by a defect in the gene that codes for the protein Artemis. However, infants with Artemis-deficient SCID – a rare subtype of the condition – are less likely to have a successful transplant due to unique genetic defects.īecause gene-replacement therapy has shown promise in treating other types of SCID, Morton Cowan at the University of California, San Francisco, and his colleagues wanted to see if it could also treat Artemis-deficient SCID. Most children with SCID will die before the age of 2 unless treated with a bone marrow transplant. It is also known as bubble boy disease, after a 1970s documentary about a child with the condition who had to live inside a sterile, plastic bubble due to the lack of a functioning immune system.

A trial found that the therapy either partially or fully restored the immune systems of 10 infants with the condition.Įach year, between 40 and 100 babies in the US are diagnosed with SCID.
