What is DIANE
DiabetesInsulin Adjustment for Normal Eating
-a way of managing Type 1 diabetes and provides people with the skillsnecessary to estimate the carbohydrate in each meal and to inject the right dose of insulin
Outline the principles of insulin therapy (4)
Right insulin - check the name
Right dose
Right time - morning/with food
Right administration - syringe/pen/pump
Why can’t therapeutic insulin be taken orally
As it’s a peptide hormone, it would be denatured by the digestive processes before it could enter the blood
How is insulin administered (2)
Subsutaneously -usually
IV - if acutely ill
Modified v unmodified insulin
Modified
-those that are more readily absorbed from the injection site and therefore act faster than natural insulin injected subcutaneously, intended to supply the bolus level of insulin needed at mealtime (prandial insulin)
Unmodified
-those that are released slowly over a period of between 8 and 24 hours, intended to supply the basal level of insulin during the day and particularly at night (basal insulin)
Basal v bolus insulin
Basal insulin, also referred to as background insulin, regulates your glucose levels in between meals, i.e. long acting insulin
Bolus insulin is extra insulin needed to manage your glucose levels after a meal, i.e. rapid or short acting insulin
When unmodified insulin is injected, what does it have a tendency to do in the subcutaneous tissue and so what implication does this have on the time it has to be injected
the insulin molecules have a tendency to self-associate into hexamers which is not an absorpable form through the capillary bed
hexamers need to dissociate into monomers first before they can be absorbed
so unmodified insulin needs to be injected at least 30 mins before eating
4 types of insulin analogues
Rapid acting
Short acting
Intermediate acting
Long acting
If someone is on 1 unit insulin per 10g CHO, how many units of insulin is needed for a banana (typically containing 30g CHO)
3 units
Why is it important to monitor BG levels at home (list a few reasons)
To adjust insulin dose if needed
To see if it’s suitable to drive (5mmol/l to drive)
DKA occurs when blood ketones level are what or above
3mmol/l
Treatment of DKA (3)
IV saline
IV potassium added to saline
IV soluble insulin (i.e. short acting)
ketone levels should decrease after 2hrs
Name some examples of rapid acting insulin analogues
Insulin lispro (brand name - humalog)
Insulin aspart (brand name - novolog/novorapid)
Name some examples of short acting insulin (aka regular or soluble insulin) analogues
Brand names:
Humulin R, S
Actarapid
Name an example of intermediate acting analogues
hypurin isophane
intermediate acting insulins aka isoprene insulins or Neutral Protamine Hagedorn insulins
Name some examples of long acting analogues (3)
Insulin glargine (brand name - Lantus) Insulin detemir (brand name - levemir) Insulin degludec (brand name - tresiba)
