Can Fecal Calprotectin Be Used as a Biomarker of Non-alcoholic Fatty Liver Disease In Obese Adolescents?

February 11, 2024 updated by: Busra Tetik Dincer, Sisli Hamidiye Etfal Training and Research Hospital
The incidence of non-alcoholic fatty liver disease (NAFLD) is increasing with obesity, and it is believed that ongoing inflammation in obesity and alterations in the enterohepatic axis contribute to this process. This study aimed to determine the role of fecal calprotectin (FCP) as an inflammatory biomarker in course of obesity and NAFLD.

Detailed Description

Obesity is a significant public health issue worldwide. With the increasing prevalence of obesity, the prevalence of metabolic syndrome in adolescents is also on the rise. Non-alcoholic fatty liver disease (NAFLD), a major cause of chronic liver disease, is the hepatic component of metabolic syndrome. The prevalence of NAFLD is not precisely known, but in some studies, it is between 22.5% and 52.8% in children with obesity, constituting 2.6% of all children. Although the mechanisms involved in the development of obesity-related metabolic complications and NAFLD are not well understood, it is believed that intestinal inflammation, changes in the microbiota, and alterations in the gut-liver axis (GLA) may play a role in the development of low-grade chronic inflammation in NAFLD associated with obesity. Fecal calprotectin (FCP), which has become increasingly important in demonstrating intestinal inflammation in recent years, is a widely used test, particularly in the diagnosis and monitoring of inflammatory bowel disease and various gastrointestinal disorders. In our study, the utility of FCP as an inflammatory biomarker in the course of NAFLD in obese adolescents has been investigated. The study was approved by our hospital's ethics committee in 15.11.2022 and another ethics committee approval was taken in 08.06.2023 for title change of study. This study conducted under the Helsinki Declaration.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • 10-18 years old healthy adolescents for control group
  • Children aged 10-18 years without any additional diseases, BMI>2 SD, no hepatosteatosis detected by ultrasonography (USG), and alanine aminotransferase (ALT) levels within normal limits were included in the obese group
  • Children aged 10-18 years without any additional diseases, BMI>2 SD, Hepatosteatosis detected by ultrasonography (USG), and alanine aminotransferase (ALT) levels higher than normal limits adjusted for gender were included in the obese + NAFLD group

Exclusion Criteria:

  • Diseases other than obesity and NAFLD

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Fecal Calprotectin Levels
Time Frame: Through study completion, an average of 3 months
Fecal calprotectin levels expected to be higher in obese adolescents, even higher in obese + NAFLD adolescents
Through study completion, an average of 3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Alanine Aminotransferase (ALT) Levels
