Hello, Raven561,
Sarcoidosis is really not an
autoimmune disease.
The disease is more common inAfrican American females
more than males.This could result from an an immune resposnse
to an infection, high sensitivity to environmental factors or
genetic factors.
A person with a close relative who has sarcoidosis is nearly
five times likely to develop the condition.
There is no direct relationship with Crohn's disease.
But , sarcoidosis can cause small ulcers in in the colon or
any where in the digestive tract.
Chest pain, cough,
shortness of breath,fatigue,fever,joint pains.
weight loss,hair loss, skin lesions called "Erythema Nodosum"
Eye symptoms,dry mouth,etc. are may all be seen.
Crohn's is not one of those that is closely associated with this.
Fecal bacteriotherapy is being considered as possible treatment
for Crohn's , but this is too soon to tell if that is the answer.
If the diagnosis is Crohn's after endoscopy and biopsy, then
he needs treatment. Now a days there are very effective
biologic drugs ti treat Crohn's and you should discuss this with your
doctor.
I wish him well.
