A Pilot Feasibility Study of Fibroblast Calcium and Glucoregulation in Health and Disease
A Pilot Feasibility Study of Fibroblast Calcium and Glucoregulation in Health

정황
상세 설명
The overall goal of this proposal is to establish a pathophysiological index of a patient's status through imaging of calcium and glucose in skin fibroblasts. The investigator will obtain skin samples from patients in the Barnstable Brown Obesity and Diabetes Center at the University of Kentucky to test the hypothesis that calcium and glucose dysregulation are present in fibroblasts from patients with Type 2 diabetes, and are exaggerated in more difficult-to-treat patients or those with poor glucose control. The innovation of the project focuses on results that can potentially lead to earlier treatment for patients with diabetes and thereby reduce the risk for long-term complications.
Three levels of analyses will be conducted to assess the relationship between Ca2+ and glucose homeostasis in four patient groups (lean non-diabetics, obese non-diabetics, Type 2 Diabetics with good glucose control, and Type 2 Diabetics with poor control.
Participants will be required to attend only one study visit that will last approximately 2-3 hours. During the study subject will undergo the following: 1. Collection of two 4 ml tubes of blood for adiponectin analysis, 2. A skin biopsy, 3. Collection and review of medical history and current/past medication use 4. Collection of demographic information, 5. Height and weight measurement 6. Body mass index evaluation, 7. Vital signs assessment (blood pressure, pulse).
Follow-up for all enrolled patients will occur on a yearly basis through a phone interview.
The punch biopsy will be performed under local anesthesia.

디자인 세부사항
코호트 및 개입
그룹/코호트 |
|---|
|
Lean Non-Diabetic Group
Variables measured will also include serum analyses (HbA1c, adiponectin, cholesterol) and patient vital signs.
|
|
Pre-diabetics
These patients are anticipated to have elevated BMI, yet not be diabetics.
|
|
Diabetic Patients
These patients will have good glucose control.
|
|
Diabetic patients with poor glucocontrol
These patients are anticipated to have poor glucose control.
They are usually taking insulin.
