A Cross-sectional Study on IBS Subtypes, Chinese Medicine Pattern &

Status Completed

Clinical Trial Summary

The investigators will conduct a cross-sectional study to discovery the distribution of IBS subtypes who would like to seek TCM treatment and their TCM patterns. At the same time, the investigators will also collect the serum, urine and stool samples of the participants to explore the host-gut microbiota metabolic interactions associated with IBS subtypes.

Clinical Trial Description

It is a cross-sectional study to discovery the distribution of IBS subtypes who would like to seek CM treatment and their CM patterns.Serum, urine and stool samples of the participants will be collected from 400-600 IBS participants to explore the host-gut microbiota metabolic interactions associated with IBS subtypes. The primary outcome will be the distribution of IBS subtype and their CM pattern in Hong Kong population. Secondary outcomes will be the host-gut microbiota metabolic interactions associated with IBS subtypes, the relationship between CM pattern and their microbiota and metabolic profiling. The relationship between IBS subtype distribution and other predetermined factors will be assessed, including gender, age, weight, Body Mass Index (BMI), dietary habit, education, economical status, the overall and individual IBS Symptom Severity Scale (IBS-SSS), syndrome of Chinese medicine, QoL assessment and Bristol Stool Scale.For those who had fulfillment of the Structured Clinical Interview for DSM-5 Disorders—(SCID-5), the Hamilton Depression Rating Scale (HAMD-17), Clinical Global Impression-severity (CGI-S), and Self-Rating Depression Scale (SDS) will also be assessed. After the collection of serum, urine and stool samples, bacterial total DNA will be extracted, purified,concentrated,dried and stored for further fecal 16s rRNA sequencing analysis. A number of parameters, including serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphate (ALP) et al., will be measured in serum. Total BA and BA profiles in serum and feces will be tested as well. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
