ok so here's my paper for biology tell me whatcha think I thinks it's confusing... Immune Deficiency diseases Did you know that if part of your immune system is missing it’s called an immune Deficiency disease? Well that’s what it is. Immune deficiency diseases can be inherited, but there are some that aren’t. For example the acquired immunodeficiency disease (AIDS) comes from HIV. You can also get them from infections or illnesses. Scientists have discovered that we have two types of immunity. There’s antibody medicated immunity and cell medicated immunity. They have found that using this information there is a way to do bone marrow transplants for treatment for immune deficiency diseases. Immune deficiency disease is when either part of your immune system is missing or doesn’t function right. Immune deficiency can be inherited or is caused by infections. The problem is if part of the immune system is missing then the body can’t fight off infections as well. SCID or Sever combined immunodeficiency is when the B-and T-lymphocytes are defected and can’t defend the body from infections from viruses, bacteria, and fungus. Most people with this disease can die before there first year of life. They end up having recurring infections such as pneumonia, meningitis and chicken pox and their immune system can’t fight them off. This disease is also called the “Boy in the bubble disease,” and all forms of this disease are inherited. Immune deficiency disease, or immunodeficiency disease, is when you are born with a part of your immune system either missing or defective. It’s when a main part of the immune system fails, and doesn’t respond. Immune deficiency makes it so that the victim cannot fight off harmful things from the body. Because of this the people that have an immune deficiency disease get many infections that are worse then what people with out immune deficiency disease and the infections last longer. Scientists have found that people have two types of immunity. People have antibody medicated immunity, and cell medicated immunity. Knowing this they have found away to do bone marrow transplants on children as a treatment for inherited immune deficiency diseases. Pathways for both types come from stem cells in the bone marrow. Using this they have treated children with inherited immune deficiency diseases. There are also other ways of treatment to. Gamma globulin is used when the person with the disease can not produce enough antibodies or immunoglobulins. Then there is Gamma interferon which is given as an injection and then there’s gene therapy. Gene therapy is when they insert a gene into a cell that has the defected gene. Even though there are a few treatments bone marrow transplant is the most commonly used. There are ways to detect immunodeficiency diseases. Here are some of the signs according to http://www.utoronto.ca/kids/Immuno deficiency.htm. • Eight or more new ear infections in one year. • Two or more serious sinus infections in one year. • Two or months on antibiotics with little effect. • Two or more pneumonias within one year. • Failure of an infant to gain weight or grow normally. • Recurrent or deep abscess in the skin or organs. • Persistent thrush in the mouth or on skin, after age one. • Need for intravenous antibiotics to clear infections. • Two or more deep seated infections such as meningitis, osteomyelitis, cellulites, or sepsis. • A family history of primary immunodeficiency And some other signs from this same web site include; • Infections responding poorly to treatment with antibiotics • Delayed or incomplete recovery from illness • The presence of certain types of cancers (such as Kaposi's sarcoma or non-Hodgkins lymphoma) • Certain opportunistic infections (such as Pneumocystis carinii pneumonia or recurrent fungal/yeast infections)
