Disorders of the Immune System

Introduction

The purpose of the immune system is to keep out of the body to infectious microorganisms such as certain bacteria, viruses and fungi, and to destroy any infectious microorganisms that do invade the body. The immune system is made up of a complex and vital network of cells and organs that protect the body against infection.

The immune system is the body's most efficient self defense against all types of parasites and stronger mechanism. As soon as it gets to an immune system that enacts and completely destroyed. There are several harmful bacteria, viruses and other foreign organisms that have a high potential to induce lethal infections in the human body. Our immune system produces special antibodies for each of these microorganisms. Therefore, if it were not for our immune system, we have been victims of some infection or other. However, a system malfunctioning immune system can wreak havoc on the body, causing many diseases and disorders (Calvo et.al, 2012).

Discussion

Disorder of the Immune System

Diseases and disorders of the immune system are classified according to the activity of the immune system. An overactive immune system has great potential for both the induction of health risks as an active immune system. Following is the list of disorders of the immune system, depending on the activity of the immune system.

Active Immune System Diseases

Immune deficiency conditions: This is the largest group of diseases of the immune system and has a variety of diseases that suppress the immune system. Often, the cause of the condition is a chronic underlying immunodeficiency disease. The symptoms of immune deficiency conditions are the same as that of the underlying disease.

SCID: SCID is a disorder of the immune system that is hereditary. SCID cause a series of genetic abnormalities, particularly in the X chromosome There are several types of recurrent infections are common in people suffering from SCID. Moreover, they are also prone to meningitis, pneumonia, measles, chickenpox, cold sores, blood disorders, autoimmune diseases, etc. in children with SCID, are evident in the first 3 months of birth.

AIDS: HIV / AIDS is a serious immunological failure and the leading cause of death worldwide. AIDS occurs in the later stages of HIV disease progression and causes the body's immune system to fully close. AIDS is considered a life-threatening disease, sexually transmitted, but can be transmitted by means of blood transfusion also. The chances of survival in AIDS patients are negligible, if diagnosed at later stages. The symptoms of the immune system for AIDS-related range of common cold and flu to serious, such as pneumonia and cancer.

Overactive Immune System Disorders

Allergies: Allergies can be defined as an aggravated immune response to a normally harmless substance. There are thousands of allergens, such as pollen grains, mold spores, latex rubber, and certain foods such as peanuts or drugs such as penicillin, etc., which can cause allergies.  Although allergy symptoms are often a result of mild, medical intervention is recommended to diagnose the underlying problem.

Anaphylaxis: Anaphylaxis is a severe and extreme form of allergy. In this condition, the allergen, like the bite of food, medicines or insect acts as a trigger and produces a ...
