Rheumatic fever-A dreadful heart disease-By Dr.Deepti M

Dreadful Heart DiseaseRheumatic fever is affecting many people throughout the world, yet many people are not aware about this disease. Generally, people think that this is some sort of fever, by looking at its name, but this is one of the most important conditions related to the heart.

Rheumatic fever is a type of hypersensitivity reaction. Hypersensitivity is the abnormal or excessive reaction of the immune system to certain particles called antigens. Antigens are any substances, which your body recognizes as being foreign to your body, or as foreign particles. Rheumatic fever is a type 2 hypersensitivity reaction.

Why is Rheumatic fever caused?

Rheumatic fever is caused due to the infection of the body with a bacteria called Group A beta hemolytic streptococcus or Streptococcus pyogenes. This Bacterium enters the body from sore throat or when having certain types of skin infection, which enters the body through the wounds.

So, we need to be really careful when we suffer from sore throat or wounds on the skin. If we are not careful, we might end up getting rheumatic fever. We need to consult a doctor immediately and take some antibiotics to kill the infection, and to prevent further damage.

Both the bacteria and our body have some type of proteins, which are quite similar in their structure. Our body has protein C and the bacteria have protein M, which look similar. So, our immune system gets confused and starts acting on our own body, by producing auto-antibodies against our body. This causes damage to our body cells.
