It has been found that there are five million people who have been affected with systemic lupus erythematosus (SLE), across the globe. The disease is autoimmune in nature and increases further if a person has scarcity of vitamin D in the body.

If the problem is not treated on time then it is said that it can cause kidney disease also. A group of Australian researchers revealed about the vitamin D role in the disease. Lead researcher Eric Morand, who is the head of the Monash lupus clinic, was of the view that not many causes are known about the disease except the fact that lupus immune system attacks human body.

It is very important for a person suffering from lupus to avoid sun as it can aggravate the problem. However, it has also been found that the action can lead to shortage of vitamin D in the body and further leads to disease severity.

"The instances of vitamin D deficiency can be seen in cultural groups where clothing covers the body, in people with dark skin tone who have lower absorption", said Eric. In order to reach at the above given result, the study researchers assessed five years of clinical data.
