Discuss the impact of an auto-immune disease and its impact on the immune system By Kayleigh Solomon Nursing A. In this essay the researcher will discuss the impact of Multiple Sclerosis and how it affects the immune system; the essay will also include the impact of allergies on the immune system discussing secondary defense mechanisms. "Multiple Sclerosis (MS) is a disease affecting nerves in the brain and spinal cord, causing problems with muscle movement, balance and vision" www.nhs.uk. The reason behind Multiple Sclerosis remains unknown, however researchers suggest there could be a number of factors including, immunologic which is when there is an abnormal immune system response, environmental factors, genetic although MS is not passed via genes there is more chance of it developing in an individual where the family is already effected, and infectious agents researcher believe there is a possible virus or infectious agent which triggers MS. ...read more.

after diagnose, Primary-progressive MS which involves continuous or worsening symptoms from the beginning and Progressive-relapsing MS which is relatively rare and combines relapse with steady worsening www.mssociety.ca.en Multiple Sclerosis is an auto-immune condition which means the body recognizes the cells as foreign and mistakenly attacks healthy body tissues, when this occurs the body?s secondary defense mechanisms start working together in an attempt to eliminate the disease. "Immunity is one of the body?s ways of resisting infection. White blood cells and antibodies attack germs they recognize and destroy them" Minett. P, 'et al' (1992) page 176. Other secondary defense mechanisms involved are, the neutrophil which is capable of ingesting and killing bacteria and is an important defense against infection. ...read more.

Conclusion

A, 'et al' (2004). There are any types of allergies and they effect different tissues and may have a local or general effect. Strawberries for example stimulate histamines which are released by the immune system as a response to what the body considers foreign pathogen. Histamine in an allergy to strawberries may lead to swelling as well as itchy or watery eyes. www.health-benefits-of.org. Peanuts are a more common food allergy where the immune system overreacts to the protein content believing it is a harmful invader leading to trouble breathing, coughing or even throat tightness. www.kidshealth.org In conclusion the researcher has discussed the impact of an auto-immune disease and the impact of the immune system as well as the impact of allergies. The conclusion formed from this document is that the immune system does not always do the correct thing for the body however at the time of doing it, believes that it is protecting the body. ...read more.
