Sarcoidosis

Definition

Sarcoidosis is a disease that forms round spots called granulomas in organs in the body. The most common places they form are in the lungs and lymph nodes.

Causes

Inflammation is how the body acts toward an infection or injury. It should go away when you are healed. It does not pass in people with sarcoidosis. The cells that cause it stay and cause granulomas. It is not known why this happens. It may be due to genetics or the environment.

Risk Factors

Sarcoidosis is more common in women who are 20 to 40 years old. It is also more common in people of African and Northern European descent.

Other things that may raise your risk are:

Family members with sarcoidosis
Working or spending time in dusty or moldy environments

Symptoms

There may not be symptoms at first. Symptoms that happen depend on the organs that are involved. They may be:

Fever
Weight loss
Night sweats
Tiredness
Breathing problems, such as shortness of breath and wheezing
Cough
Chest pain
Rapid heart beat
Lightheadedness or vertigo
Facial paralysis, such as Bell palsy
Problems hearing, speaking, and swallowing
Headache
Seizures

Bell Palsy

Diagnosis

You will be asked about your symptoms and health history. A physical exam will be done.

A biopsy may be done to look for granulomas.

Images may be taken to view your lungs and lymph nodes. This can be done with

Other tests may be done to see how well your organs are working. These may be:

Blood and urine tests
Eye exam
ECG—to test heart health
Pulmonary function tests—to test lung health
MRI scan—to test nervous system

Treatment

There is no cure. Treatment is aimed at managing symptoms. Eye and lung exams will be needed to watch for changes over time. Treatment choices are:

Medication

These medicines may be used:

Corticosteroids to ease inflammation
Medicine to suppress the immune system
Tumor necrosis factor antagonists to ease inflammation
Antimicrobial drugs to treat skin problems

Surgery

Organ transplant of the heart, lung, liver, or kidneys may be needed in people who are not helped by medicine.

Prevention

There are no prevention methods.
