Steroid-induced Hyperglycemia Case Study~Betty~ 67 yo Caucasian woman Presents with complaint of “very high” glucose readings for the last 3 days Last appointment 4 days ago for URI with hx of COPD Last wellness appointment was 1 month ago Up until she became ill, her diabetes was “well controlled.” She states that her blood sugars began to trend higher than usual when she 1st became sick, however she believes she is having an allergic reaction to her medicationsbecause they have never been as high as they are now “not even when I was initially diagnosed with diabetes.”

What are YOUR concerns? • Allergic reaction? • reassurance • Hyperglycemia • Cause(s)? • What is the typical pattern of steroid-induced hyperglycemia? • Minimal effect on fasting glucose, often are normal • Exaggeration of postprandial glucose that will lead to elevated BGs all day • Degree of elevation correlates with previous glucose tolerance, worse for those with pre-existing DM • TRANSIENT • blood glucose will drop as steroid dose reduced • return to baseline once steroid stopped if no GLUCOTOXICITY
Treatment Strategies • If diet/exercise controlled: • add metformin or SFU or both • If already taking medication for DM, will likely need insulin ADDED • Basal: • NPH Vs. long-acting analog (Lantus or Levemir)
s.c. injection Basal Insulin Replacement Therapy Normal Insulin Secretion at Meal Time Insulin Glargine/Detemir NPH Insulin Change in Serum insulin Time (hours)
Treatment Strategies • If diet/exercise controlled • add metformin or SFU or both • If already taking medications for DM, will likely need insulin ADDED • Basal: NPH Vs. long-acting (Lantus or Levemir) • Prandial: analog Vs. Regular
s.c. injection Bolus Insulin Replacement Therapy Normal Insulin Secretion at Meal Time Rapid-acting Analog Regular insulin Change in Serum insulin Time (hours) Apidra Humalog Novolog
Treatment Strategies • If diet/exercise controlled • add metformin or SFU or both • If already taking medications for DM, will likely need insulin ADDED • Basal: NPH Vs. long-acting (Lantus or Levemir) • Prandial: analog Vs. Regular • Pre-Mixed
s.c. injection Mixed Insulin Replacement Therapy Normal Insulin Secretion at Meal Time Analog Mix PreMix 70/30 (NPH/REG) Change in Serum insulin Time (hours) 75/25 Humalog Mix 70/30 Novolog Mix
Treatment Strategies • If diet/exercise controlled • add metformin or SFU or both • If already taking medications for DM, will likely need insulin ADDED • Basal: NPH Vs. long-acting (Lantus or Levemir) • Prandial: analog Vs. Regular • Pre-Mixed • Do nothing and wait it out? • Glucotoxicity • Dehydration • HHS/DKA
What do I do TODAY? Continue metformin Hold the SFU Start NPH in AM with prednisone dose Add either REG or analog before meals Reduce insulin doses by 10-20% with each reduction of steroid dose Consider IV rehydration (1 liter NS) and push oral fluids (non-caloric)
Other steroids: Decadron and CSI • How would you expect blood sugar pattern to look? • How might this affect your treatment options? • NPH or analog basal (Lantus or Levemir)
