About this trial

This study evaluates the relationship between vitamin-D status and severity of sarcoidosis, and the effects of vitamin-D repletion in vitamin-D insufficient patients with sarcoidosis. Half the patients with sarcoidosis who are vitamin-D insufficient will receive standard vitamin-D supplementation via standard regimen while the other half will receive a placebo. Sarcoidosis patients who are vitamin-D sufficient will also act as controls.

Trial outcomes

Primary outcomes

1

Change in lung function from baseline

(Measurement at end of study)/(measurement at enrollment)

Time frame
Baseline and 24 weeks

Secondary outcomes

1

Change in King's Sarcoidosis Questionnaire Score

Standard validated questionnaire for assessing the impact of sarcoidosis on quality of life. Questions address symptoms, activities and psychosocial impacts of disease. It consists of 29 questions on general health, medications, and symptoms in lung, skin, and eyes, summed to derive a total score. Each question is scored on a scale of 1 (worst) to 7 (best). Minimum total score = 5 (poorest health). Maximum total score = 203 (best health).

Time frame
Baseline, 12 and 24 weeks
2

Change in six minute walk distance

(Measurement at end of study)/(measurement at enrollment)

Time frame
Baseline and 24 weeks
3

Change in blood cell counts from complete blood count (CBC)

(Measurement at study point)/(initial measurement at enrollment)

Time frame
Baseline, 12 and 24 weeks
4

Change in metabolic profile from complete metabolic panel (CMP)

(Measurement at study point)/(initial measurement at enrollment)

Time frame
Baseline, 12 and 24 weeks
