Study Notes
Insulin Therapy for Diabetes Mellitus
- Type 1 diabetes mellitus patients and some type 2 diabetes mellitus patients require multiple daily insulin injections or infusion pump therapy to manage their condition.
- Insulin titration is challenging due to the need to balance insulin doses with food intake, avoid hypoglycemia, and maintain good blood glucose control.
History of Insulin Therapy
- Insulin therapy for diabetes was first discovered in 1921 and has evolved to include various types of insulin.
- Genetic technology advancements allow for the production of human insulin from altered bacteria or yeast, making it potentially cheaper and more purified.
Types of Insulin
- There are six broad categories of insulin: pre-mixed insulin, long-acting insulins (Glargine and Detemir), intermediate-acting insulins (NPH), short-acting insulin, and rapid-acting analogues (Aspart, Lispro, and Glulisine).
- Insulins are categorized based on their onset, timing, and duration of action.
Insulin Delivery Methods
- The most common method of insulin delivery is injection, which can be uncomfortable and painful.
- Advancements in insulin delivery methods since the 1980s include smaller needles and syringes to reduce pain and predictability of injecting into muscle.
Barriers to Insulin Therapy
- Psychological resistance to needles and insulin injections is a significant barrier to their use, affecting both users and health professionals.
- Some individuals may have aversion to needles due to factors such as diminished visual acuity, tremors, cataracts, or retinopathy.
Importance of Insulin Therapy
- Insulin therapy is crucial for people with type 1 and type 2 diabetes to prevent or delay complications.
- Insulin therapy can prevent or delay the development of further complications, and early treatment can prevent subsequent MI, CVD events, and death.
Challenges and Future Directions
- The optimal therapy for type 1 diabetes should contain both prandial and basal insulin, while the regimen for type 2 diabetes is not as well defined.
- The increasing number of new insulin analogs and modes of delivery will provide more options to further customize hormone replacement therapy.
- Barriers to insulin therapy must be addressed at the patient, provider, and system level to promote successful insulin initiation and long-term maintenance.
