About this trial
This is an interventional treatment trial for Hyperglycemia Steroid-induced focused on measuring steroid, prednisone, methylprednisolone, hyperglycemia, insulin, hypoglycemia

NPH Insulin
Basal/Bolus Insulin
NPH will be given at the time of steroid administration to the patient in addition to standard basal/bolus insulin the patient may be receiving in the following doses: Prednisone Dose (mg/day) - NPH dose (U=Units): 10-20 mg/day - 1.2U (units)/mg; 21-40 mg/day - 0.6U/mg; 41-60 mg/day - 0.45U/mg; 61-80 mg/day - 0.3U/mg; >80 mg/day - no additional NPH. Note that the amounts of NPH are added to each other for the various prednisone doses. For example, a dose of 75 mg/day of prednisone would come out to be (1.2U x 20mg = 24U) + (0.6U x 20mg = 12U) + (0.45U x 20mg = 9U) + 0.3U x 15 mg = 4.5U) for a total of 24 + 12 + 9 + 4.5 = 49.5U of NPH for 75 mg of prednisone.
Basal insulin (glargine) and Bolus insulin (insulin aspart) will be increased (doses given in U [units]/kg) according to the Prednisone dose (mg/day) as follows: Prednisone Dose (mg/day) - doses of insulin (U/kg): Prednisone 0 mg - Glargine 0.25U/kg, Bkfst Aspart 0.08U/kg, Lunch Aspart 0.08U/kg, Dinner Aspart - 0.08U/kg; Prednisone 10-20 mg - Glargine 0.25U/kg, Bkfst Aspart 0.1U/kg, Lunch Aspart 0.15U/kg, Dinner Aspart - 0.2U/kg; Prednisone 21-40 mg - Glargine 0.25U/kg, Bkfst Aspart 0.1U/kg, Lunch Aspart 0.2U/kg, Dinner Aspart - 0.25U/kg; Prednisone 41-60 mg - Glargine 0.30U/kg, Bkfst Aspart 0.15U/kg, Lunch Aspart 0.25U/kg, Dinner Aspart - 0.30U/kg; Prednisone 61-80 mg - Glargine 0.30U/kg, Bkfst Aspart 0.15U/kg, Lunch Aspart 0.30U/kg, Dinner Aspart - 0.35U/kg; Prednisone >80 mg - Glargine 0.30U/kg, Bkfst Aspart 0.15U/kg, Lunch Aspart 0.35U/kg, Dinner Aspart - 0.40U/kg.
