Wolfram Syndrome 1 in Two Brothers Treated with Insulin Pump.

Background/Objective: Wolfram syndrome (WS) is a rare genetic disorder, in which patients develop early-onset diabetes mellitus (DM), optic nerve atrophy, and neurodegeneration, which has no specific treatment available. Here, we report 2 brothers treated with an insulin pump to manage the alterations of the glycemic levels due to the DM. Case Report: We present the case of 2 siblings diagnosed with Wolfram syndrome 1, they presented with typical endocrinological and neurodegenerative early manifestations, one brother was treated with a sensor-augmented insulin infusion system, and the other with an insulin pump. Both reached a better metabolic state and had improved quality of life. Discussion: The management of WS is still a challenge; however, the use of a sensor-augmented insulin infusion system and the information that it provides may offer better care to patients who require frequent monitoring and adjustments in their treatment. It has been reported that the neurodegenerative progression of WS is also associated with high glucose peaks; therefore, it is necessary to control it, even when it is hard due to the difficult-to-manage DM. There is only 1 previous case report of WS with insulin pump that describes the benefits of continuous subcutaneous insulin infusion and tight metabolic control during pregnancy. Conclusion: The use of insulin pumps may be an effective treatment for DM in WS patients, mainly in terms of improving the prognosis of difficult-to-manage DM.
