Sarkoidose

Sarkoidose is an inflammatory disease characterized by the formation of granulomas, which are small collections of inflammatory cells, in various organs. The most commonly affected organs are the lungs and lymph nodes, but it can also impact the skin, eyes, liver, heart, and nervous system. The exact cause of sarkoidose remains unknown, but it is believed to be an immune system response to an unknown substance, possibly an infection or environmental trigger, in genetically susceptible individuals.

Symptoms of sarkoidose vary widely depending on which organs are involved and the severity of the inflammation. Pulmonary involvement can lead to a dry cough, shortness of breath, and chest pain. Skin manifestations may include rashes, nodules, and erythema nodosum, a painful condition causing red lumps on the shins. Eye symptoms can range from blurred vision to inflammation of the uvea. Fatigue, fever, and weight loss are also common systemic symptoms.

Diagnosis of sarkoidose typically involves a combination of medical history, physical examination, imaging studies such as chest X-rays or CT scans, and laboratory tests. Biopsies of affected tissues are often performed to confirm the presence of granulomas. There is no specific cure for sarkoidose, and treatment aims to manage symptoms and reduce inflammation. Many individuals experience spontaneous remission. For those with persistent or severe symptoms, corticosteroids are the primary treatment, though other immunosuppressive medications may be used. Regular monitoring is important to track disease progression and potential organ damage.
