Wegener's granulomatosis is a serious disease and without
treatment can
be fatal within months. Treatment is directed toward stopping
the
inflammation process by suppressing the immune system.
Medications used to
treat Wegener's granulomatosis include high-dose cortisone
(prednisone)
and the immunosuppressive drug cyclophosphamide
(Cytoxan). Recent reports also suggest that trimethoprim/sulfamethoxazole (Bactrim) can
also be
helpful to prevent relapse of disease activity in patients with
Wegener's granulomatosis.
Cytoxan that is taken by mouth with prednisone until the disease is in remission and then switched to methotrexate for
two years and tapered off has been reported to be effective and less toxic than the traditional long-term Cytoxan treatment.
Methotrexate has recently been introduced as a drug for Cytoxan treatment failures. Moreover, it now appears that Cytoxan will not be necessary in order to maintain long-term remission and that doctors can convert to the less toxic methotrexate for maintenance. The reports also demonstrate that methotrexate can eventually be tapered off entirely after
two years. Azathioprine (Imuran) has also been used as a maintenance medication after Cytoxan. Recently, intravenous immunoglobulin therapy (IVIG) has been shown to be helpful in treating relapses of Wegener's granulomatosis. Also, preliminary studies suggest that rituximab (Rituxan) may be helpful to maintain remission once the initial inflammatory disease has been controlled using medications mentioned above. These new regimens are welcome news for patients with Wegener's granulomatosis as medical researchers are searching for better treatments.
Sinus infection (sinusitis) signs and symptoms include headache, fever, and facial tenderness, pressure, or pain. Treatments of sinus infections are generally with antibiotics and at times, home remedies.
Vasculitis is a general term for a group of uncommon diseases which feature inflammation of the blood vessels. Each form of vasculitis has its own characteristic pattern of symptoms. The diagnosis of vasculitis is definitively established after a biopsy of involved tissue demonstrates the pattern of blood vessel inflammation. Treatment is directed toward decreasing the inflammation of the arteries and improving the function of affected organs.
Relapsing polychondritis is an uncommon, chronic disorder of the cartilage that is characterized by recurrent episodes of inflammation of the cartilage of various tissues of the body. Tissues containing cartilage that can become inflamed include the ears, nose, joints, spine, and windpipe (trachea). Tissues that have a biochemical makeup similar to that of cartilage such as the eyes, heart, and blood vessels, can also be affected. Nonsteroidal antiinflammatory medications (NSAIDs) is used as treatment for mild cases of the disease. Steroid-related medications also are usually required.
