Glucocorticoids and immunosuppressants
Despite therapeutic intervention, the disease can have a fatal outcome, even if the patient is young, said Dr. Müller-Ladner. Glucocorticoids are the current therapy of choice. The dose is more than 0.5 mg of prednisolone equivalent per kg of body weight. “This usually leads to a rapid improvement in the inflammation. Subsequently, every organ is thoroughly diagnosed to assess the severity of the disease and to plan further treatment steps.”
In the long term, proven immunosuppressants, such as azathioprine, mycophenolate, leflunomide, and methotrexate, can be used, just as for many other chronic inflammatory diseases. Cyclophosphamide or cyclosporine is used more rarely, owing to their side effect profiles.
Because of the B-cell dominance, B-cell–depleting therapy with rituximab is currently a highly effective therapeutic option but one that must be applied for, because such use is off label. “If the body responds well to the medication, organ function often recovers,” said Dr. Müller-Ladner.
