A case of an elderly patient with insulin-dependent diabetes and dementia receiving one basal insulin plus one bolus insulin injections a day for 6  months

AbstractMultiple daily injections of insulin, referred to basal –bolus regimen, are generally essential in achieving glycemic control and preventing ketosis in insulin-dependent diabetes, such as type 1 diabetes (T1D). A 75-year-old man with T1D receiving basal–bolus insulin therapy exhibited symptoms of dementia after hospitalization due to pyelonephritis a nd failed to continue insulin self-injection. Given that his social and familial circumstances allowed insulin injection once a day during the morning, bolus insulin injections needed to be discontinued. Ketonuria was observed the day following discontinuation of bolus insulin. Although increasing t he basal insulin dose (degludec) from 10 to 15 units improved ketonuria, his preprandial glucose levels increased to ≥ 500 mg/dL before lunch and ≥ 400 mg/dL before dinner. Hence, another bolus insulin injection was simultaneously added to the basal insulin dose before breakfast, which , subsequently, decreased his preprandial glucose levels to ≤ 220 mg/dL before lunch and ≤ 350 mg/dL before dinner. For half a year after discharge, ketonuria or hypoglycemia had not been detected. After 6 months, he was able to restart intensive insulin therapy with familial support. Hence, in cases where elderly patients with diabetes exhibit symptoms of dementia and can receive insulin injection once a day due to their social circumstances, short-term one basal plus one bolus insulin injections a day might be ...
