Autoimmune Diseases

September 16, 2008

The immune system is basically a set of organs and cells that coordinate to protect the body against bacteria, viruses, parasites and fungi. The autoimmune diseases include ailments in which the immune system starts producing antibodies to attack the body’s own healthy cells and tissues. Autoimmune disorders are either confined to thyroid gland or the pancreas gland, or they affect the whole body.  The reason some people’s immune systems begin attacking their own bodies are not known. Autoimmunity is not contagious, but the genes a child inherits from parents can influence whether a child will develop autoimmune conditions. Scientists are continuing to study the role of environmental toxins, viruses and certain drugs in causing the immune system to function improperly in this manner.

Acute autoimmune problems are complicated to diagnose and not easy to treat. Diagnosis and treatment may differ in different individuals. These diseases can grow slowly or move quickly. The symptoms can be visible and invisible at times. In order to check the intensity of autoimmune conditions, experts use various imaging and laboratory tests.   The tests are done to check the presence of antinuclear antibodies (ANA) complement levels.  Lower concentration of complement in the blood indicates immune and autoimmune disorders.

Complete blood count (CBC) is an important and primary diagnostic check up. It includes measurement of the size, count and age of different blood cells characteristically involved in inflammation, coagulation and oxygen transportation.

Creatinine is a blood test to determine kidney function. Erythrocyte sedimentation rate is another test of blood to check the time of red blood cells to fall at the bottom of a test tube. In case of swelling and inflammation, the blood proteins stimulate blood cells to cluster faster than normal. Rapid sedimentation indicates severe inflammation.
Hematocrit is a test to evaluate the count of red blood cells in a sample of blood.
