Gastrostomy in patients with prion disease

摘要

Patients with prion diseases can live for long periods of time in a state of akinetic mutism given appropriate management of their symptoms. To study symptom support in these cases, we performed gastrostomies on 3 patients with V180I genetic Creutzfeldt-Jakob disease (CJD) who had become akinetic and mute, and compared them to 14 other similar patients being fed by tube. In the 3 gastrostomy cases, there were no direct complications due to the gastrostomy or tube feeding, nor were there episodes of discontinuation of tube feeding or initiation of continuous drip infusion due to severe complications. Antibiotics were administered for mild infections, a complication of CJD, with 0.2% and 8.8% of the total time after gastrostomy being used for intravenous or transluminal administration, respectively. We compared the present patient series with that of our previous report statistically, and found that patients undergoing gastrostomy required significantly fewer discontinuations of tube feeding than those who did not. No significant difference in antibiotic administration was found between groups, however. It is our conclusion that gastrostomy should be allowed for symptom support in akinetic patients with prion disease, but adequate informed consent must be provided to the patient's family.
