Establishment and Clinical Application of Pancreatic Endocrine and Exocrine Function Tests
Study Overview

Detailed Description
Pancreatic exocrine insufficiency (PEI) refers to the reduction in the synthesis and secretion of pancreatic enzymes caused by various reasons, which leads to malabsorption and even nutritional deficiencies. The main causes of PEI include chronic pancreatitis (CP), acute pancreatitis, pancreatic cancer, pancreatectomy, enterectomy, diabetes mellitus and cystic fibrosis. Due to its numerous etiologies, the current prevalence of PEI is uncertain and very varied. The prevalence of PEI in the Chinese population is still lacking. Diagnosis of PEI in clinical practice is hindered by the lack of accurate tests, and it usually requires the combination of symptoms, nutritional markers and a noninvasive pancreatic function test in the appropriate clinical context. At present, the fecal elastase-1 (FE-1) test is the most widely applied non-invasive approach in routine clinical practice.
First, the study plans to record the baseline data of participants and perform the FE-1 test in specific elderly population and community population, in order to improve the epidemiology of PEI in China.
Second, the study will perform the FE-1 test in 100 CP patients, in order to determine the FE-1 cut-off value for the classification of PEI (mild-moderate and severe), using the coefficient of fat absorption as the "gold standard".
Third, people with CP often have diabetes mellitus which is described as type 3c diabetes mellitus (T3cDM). However, there are no recognized diagnostic criteria for T3cDM. Studies have shown that close to 50% of T3cDM cases are misclassified, most of which are diagnosed as type 2 diabetes mellitus (T2DM). According to certain research, the early stages of T3cDM are characterized by insufficient insulin and C-peptide secretion. The study will provide laboratory testing to 300 patients with T3cDM and T2DM in order to compare the differences and create T3cDM diagnostic criteria.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Chronic pancreatitis
Patients with chronic pancreatitis are considered as study subjects.
If a CP patient has diabetes mellitus (exclude type 1 diabetes mellitus), a blood test will be performed to assess glycemic control.
|
Enrolled subjects will eat a standard meal (100g of fat) daily for five consecutive days and collect stool samples for the last 72h.
The fat content in the sample will be quantitatively detected and the fat absorption coefficient will be calculated.
The enrolled subjects will undergo oral glucose tolerance test and will be collected blood samples for measurement of plasma glucose, insulin level, C-peptide level, glycosylated hemoglobin and vitamin.
Other Names:
Personal information of the enrolled subjects will be collected and a fecal collection device will be distributed.
Fecal elastase-1 levels will be measured after the fecal sample is collected.
|
Type 2 diabetes mellitus
Patients with type 2 diabetes mellitus are considered as study subjects.
|
The enrolled subjects will undergo oral glucose tolerance test and will be collected blood samples for measurement of plasma glucose, insulin level, C-peptide level, glycosylated hemoglobin and vitamin.
Other Names:
Personal information of the enrolled subjects will be collected and a fecal collection device will be distributed.
Fecal elastase-1 levels will be measured after the fecal sample is collected.
|
Elderly population
The elderly population is defined as those over 60 years of age and residing in retirement home.
Excluding people with critical conditions, mental disorders that prevent them from cooperating with the study, and those who are unable to defecate due to intestinal obstruction or other illnesses.
|
Personal information of the enrolled subjects will be collected and a fecal collection device will be distributed.
Fecal elastase-1 levels will be measured after the fecal sample is collected.
|
Community population
This group is the resident population of the community.
Excluding people with critical conditions, mental disorders that prevent them from cooperating with the study, and those who are unable to defecate due to intestinal obstruction or other illnesses.
|
Personal information of the enrolled subjects will be collected and a fecal collection device will be distributed.
Fecal elastase-1 levels will be measured after the fecal sample is collected.
