Clinical Trial Summary

The goal of this observation is to establish a complete registry for the clinical manifestations, environment, genetic, and other related gene variation information of young-onset diabetic patients. Moreover, according to the physiological and pathological mechanisms of different genes, the impact on the clinical characteristics of diabetes, the therapeutic response to drugs, and the impact on complications will be analyzed.

The main questions are:

1. The distribution of different types of MODY

2. The phenotypes and clinical characteristics of different types of MODY

3. Response to antidiabetic drugs among different types of MODY

Once the participant is enrolled, their questionnaire information (including disease course and development, health history, family history, drug history, etc.), medication, outpatient/inpatient medical history, etc. will be collected and logged in. Blood and urine samples will also be collected for biochemical tests genetic testing, etc.

At the same time, the investigators will conduct a continuous follow-up on a regular basis (3 months, 6 months, 12 months, 24 months, and 5 years after the study subject is enrolled).

Young-onset type 2 diabetes will be compared to see the difference in clinical presentations and responses to antidiabetic drugs.

Description:

Diabetes and its complications rank among the top ten death causes in Taiwan. In Taiwan, besides the high prevalence, diabetes also shows a trend in younger people. Compared with type 2 diabetes which typically develops at older ages, young-onset diabetes (YOD) has a faster decline in the function of islet cells and a higher risk of complications. These young-onset diabetic patients may belong to different subtypes, and each subtype has different clinical manifestations or genetic characteristics, while the physiological and pathological mechanisms behind them are very complex and closely affect the subsequent treatment decisions. Among young-onset diabetes, maturity-onset diabetes of the young (MODY) has the most obvious genetic predisposition and family history. If the diagnosis is confirmed, it may be possible to directly target the unique defect of the relevant gene and accurately select the appropriate drug therapy to help patients achieve good blood sugar control as soon as possible. This five-year proposal is aimed to target 1,500 young-onset diabetic patients (case group) as well as 500 young-onset, but not MODY, diabetic patients (control group). Once the study subject is enrolled, their questionnaire information (including disease course and development, health history, family history, drug history, etc.), medication, outpatient/inpatient medical history, etc. will be collected and logged in. Blood and urine samples will also be collected for biochemical tests genetic testing, etc. At the same time, the investigators will conduct a continuous follow-up on a regular basis (3 months, 6 months, 12 months, 24 months, and 5 years after the study subject is enrolled). The aim of this proposal is to establish a complete registry for the clinical manifestations, environment, genetic, and other related gene variation information of young-onset diabetic patients. Moreover, according to the physiological and pathological mechanisms of different genes, the impact on the clinical characteristics of diabetes, the therapeutic response to drugs, and the impact on complications will be analyzed. It is expected that different subtypes of early-onset diabetes can be established for genetic counseling, prevention, health education, and treatment selection strategies to achieve good blood sugar and other metabolic control in time, so as to achieve individualized precision medical prevention and treatment.
