This study is looking at how vitamin D levels affect sarcoidosis (a disease causing inflammation in organs) and if giving vitamin D can help. If you have sarcoidosis and low vitamin D, you might receive either Ergocalciferol (Vitamin D2) or a placebo (a sugar pill that looks like the real medicine). Some people with sarcoidosis who have normal vitamin D levels will also be included for comparison. Researchers will measure changes in your lung function over 24 weeks to see if the vitamin D treatment makes a difference. To join, you should be at least 21 years old, have a stable medical condition, and have normal calcium levels.

Study design

This is an interventional study involving 90 participants. Half of the vitamin D insufficient sarcoidosis patients will receive Ergocalciferol, while the other half will receive a placebo.

What's involved

Your lung function will be measured at the beginning of the study and again after 24 weeks.

Compensation

Not stated in the trial record.

Follow-up

Participants will be followed for 24 weeks after starting the intervention to measure changes in lung function.
