Answer: Early diagnosis is essential for effective treatment of Acanthamoeba keratitis. Several prescription eye medications are available for treatment. However, the infection can be difficult to treat. The best treatment regimen for each patient should be determined by an eye doctor. If you suspect your eye may be infected with Acanthamoeba, see an eye doctor immediately. Skin infections that are caused by Acanthamoeba but have not spread to the central nervous system can be successfully treated. Because this is a serious infection and the people affected typically have weakened immune systems, early diagnosis offers the best chance at cure. Most cases of brain and spinal cord infection with Acanthamoeba (Granulomatous Amebic Encephalitis) are fatal.. Type: treatment. Question: What are the treatments for Sarcoidosis ?. Answer: What treatment is available for sarcoidosis? The treatment of sarcoidosis depends on : the symptoms present the severity of the symptoms whether any vital organs (e.g., your lungs, eyes, heart, or brain) are affected how the organ is affected. Some organs must be treated, regardless of your symptoms. Others may not need to be treated. Usually, if a patient doesn't have symptoms, he or she doesn't need treatment, and probably will recover in time. Currently, the drug that is most commonly used to treat sarcoidosis is prednisone. When a patient's condition gets worse when taking prednisone or when the side effects of prednisone are severe in the patient, a doctor may prescribe other drugs. Most of these other drugs reduce inflammation by suppressing the immune system. These other drugs include: hydroxychloroquine (Plaquenil), methotrexate, azathioprine (Imuran), and cyclophosphamide (Cytoxan). Researchers continue to look for new and better treatments for sarcoidosis. Anti-tumor necrosis factor drugs and antibiotics are currently being studied. More detailed information about the treatment of sarcoidosis can be found at the following links: . Type: treatment. Question: What are the treatments for CADASIL ?.
