Question

Chronic anemia and multiple sclerosis are?
A) Allergic diseases
B) Hormonal diseases
C) Autoimmune diseases
D) Hereditary diseases

Answer 1

Hint: Autoimmunity literally means protection against self, but actually it implies injury to self, therefore sometimes the term is also under criticism. The disease caused by autoimmunity is called autoimmune disease. Autoimmune diseases result from the destruction of self-proteins, cells, and organs by auto-antibodies or self-reactive T-cells.

Complete step-by-step answer:
Autoimmune hemolytic anemia is caused due to Rh autoantigen. Multiple sclerosis is caused by autoantigen which is myelin basic protein.
In multiple sclerosis, our immune system mistakenly attacks brain cells and nerves. It is due to a combination of genetic and environmental factors. This immune system eats away the protective covering of nerves. So it results in nerve damage that disrupts or interrupts the communication between the brain and the body.
Chronic anemia is also called anemia of chronic diseases. It affects people who have conditions that cause inflammation such as infections, and cancer link. The people affected by chronic anemia show symptoms like fatigue, paleness of the skin, lightheadedness, shortness of breath, fast heartbeat, irritability, chest pain, and additional findings. And there is no specific treatment for this anemia.
Hence the correct answer is Autoimmunity diseases option(C).

Note: Autoimmunity is initiated by a combination of genetic and environmental factors. Most autoimmune diseases are polygenic and affected individuals inherit multiple genetic polymorphisms that contribute to disease susceptibility. Infections may increase the chances of autoimmunity by several mechanisms including enhanced expression of co-stimulation tissues.
