Treatment of Wolfram Syndrome Type 2 With the Chelator Deferiprone and Incretin Based Therapy

Summary

Patients who are genetically diagnosed with the recently reported and rare Wolfram syndrome type 2 ( WFS2) and have the degenerative and symptomatic disease including signs such as diabetes, platelet aggregation defect or visual problems will be asked to participate in this study. Knowing the pathomechanism of WFS2 with rapid cell death, after doing baseline investigations to asses the severity of their disease, the participants will be offered a chelator therapy with in addition to the antioxidant Acetylcystein, in diabetic patients an Incertin (GLP-1 ) therapy will be offered as well. The baseline investigations will be repeated after 2 months and after 5 months of therapy in order to asses the progression of the disease and to show if the chelator and anti oxidant therapy and in diabetic patients the GLP-1 therapy could stop the progression of the disease.
