Trial Summary

Will I have to stop taking my current medications?

You may need to stop taking certain medications. The trial excludes people taking insulin secretagogues (like gliclazide or glyburide), other injectable diabetes medications (like liraglutide), and systemic steroids (like prednisone).

What data supports the effectiveness of the treatment for lipohypertrophy in diabetes?

Avoiding injection in areas with lipohypertrophy (swelling under the skin) can lead to partial or full reduction of these swellings, as seen in 6 out of 11 cases over a year. Additionally, changing the insulin type and injection sites has shown to prevent further worsening of skin issues.12345

Is it safe to use insulin injections for diabetes?

Insulin injections are generally safe, but they can cause a common side effect called lipohypertrophy, which is a lump or swelling under the skin at the injection site. This can be minimized by rotating injection sites and using proper techniques.12678

How does the treatment for lipohypertrophy differ from other treatments?

This treatment for lipohypertrophy involves avoiding repeated insulin injections in the same area, which can help reduce tissue swelling. Unlike other treatments, it emphasizes the importance of rotating injection sites to prevent and manage the condition.136910

What is the purpose of this trial?

Evaluation of insulin absorption at sites affected by clinically apparent lipohypertrophy through short-term continuous glucose monitoring has shown inconsistent results and it is yet unknown how or if subclinical lipohypertrophy affects absorption. In this study investigators propose to enroll at least 20 people who participated in phase 1 and who were determined to have subclinical lipohypertrophy to examine the correlation between glycemic control and amount of insulin injected in subclinical hypertrophic areas using capillary blood glucose and continuous glucose monitoring.

Eligibility Criteria

This trial is for people over 19 who have had Type 1 or Type 2 diabetes for at least two years and are using insulin. They must have been part of phase 1 of the study and identified with subclinical lipohypertrophy. Those on certain diabetes medications, steroids, or unable to communicate in English without a translator cannot join.

Timeline

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants are randomized to inject insulin into areas of subclinical lipohypertrophy or normal subcutaneous tissue, monitored with continuous glucose sensors

12 days
2 visits (in-person) for sensor placement and removal

Follow-up

Participants are monitored for safety and effectiveness after treatment

4 weeks

Treatment Details

Interventions

  • Lipohypertrophy
  • Normal Subcutaneous Tissue
Trial Overview The study is looking into how well insulin is absorbed in areas affected by subclinical lipohypertrophy—a kind of localized swelling due to repeated injections. At least 20 participants will use continuous glucose monitoring to see if there's a link between their blood sugar control and the amount of insulin injected into these swollen spots.
Participant Groups
2Treatment groups
Experimental Treatment
Group I: Normal Subcutaneous TissueExperimental Treatment1 Intervention
Participants inject their insulin into the abdomen into areas with normal subcutaneous tissue.
Group II: LipohypertrophyExperimental Treatment1 Intervention
Participants inject their insulin into the abdomen into areas of lipohypertrophy that were identified by ultrasound in Phase 1 of the study.
