Sleeve Gastrectomy in Adolescents With Complicated Morbid Obesity and NAFLD

September 29, 2015 updated by: Valerio Nobili, Bambino Gesù Hospital and Research Institute

Effects of Sleeve Gastrectomy on Hepatic and Metabolic Abnormalities in Adolescents With Complicated Morbid Obesity and NAFLD

Pediatric obesity has become a critical health problem worldwide, increasing the premature onset of obesity-related morbidities. This phenomenon has induce an increase in the incidence of serious health complications starting in childhood and adolescence. Lifestyle interventions, including diet and regular physical activity, are the cornerstone of current medical management. Unfortunately, these interventions are often ineffective in providing a meaningful and long-lasting weight loss necessary to change health outcomes. It has been demonstrated that an early intervention in obesity in children and adolescents, inducing weight loss by performing bariatric surgery in carefully selected patients, can dramatically reduce the risk of adulthood obesity and obesity-related diseases, including non-alcoholic fatty liver disease (NAFLD).

Recent evidence suggest that bariatric surgery can improve metabolic complications and liver involvement in patients affected by morbid obesity.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

40

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Sleeve gastrectomy
These patients are surgically treated with laparoscopic sleeve gastrectomy in association to lifestyle intervention (hypocaloric diet and physical activity)
Procedure: Laparoscopic Sleeve gastrectomy (LSG)

These patients (no. 20) are assessed by clinical and psychological evaluation (auxological parameters, blood pressure and personal and family history), blood tests (liver function test's (LFT's), uric acid, lipid and gluco-insulinemic profile with oral glucose tolerance test (OGTT)), abdominal ultrasound at time of enrollment.

They are treated with laparoscopic sleeve gastrectomy associated to lifestyle intervention. Concomitantly to surgical intervention, liver biopsy is performed.

At 6 and 12 months after LSG the patients are evaluated with laboratory, clinical and echographic assessment. Moreover, one year after LSG liver biopsy is repeated.
Experimental: Lifestyle Intervention
These patients are treated with lifestyle intervention (hypocaloric diet and physical activity)
Behavioral: Lifestyle Intervention

These patients (no. 20) are assessed by clinical and psychological evaluation (auxological parameters, blood pressure and personal and family history), blood tests (liver function test's (LFT's), uric acid, lipid and gluco-insulinemic profile with oral glucose tolerance test (OGTT)), abdominal ultrasound at time of enrollment.

They are treated with lifestyle intervention. At 6 and 12 months after enrollment the patients are evaluated with laboratory, clinical and echographic assessment.

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
Improvement of metabolic parameters
Time Frame: 12 months
Improvement of serum levels of cholesterol (mg/dl), triglycerides (mg/dl), HDL (mg/dl), LDL (mg/dl), uric acid (mg/dl), and gluco-insulinemic profile (serum concentration during standard oral glucose tolerance test - OGTT)
12 months
Improvement of liver parameters
Time Frame: 12 months
Improvement of Aspartate aminotransferases (U/L) and Alanine aminotransferases (U/L) serum levels
12 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
Improvement of liver histology
Time Frame: 12 months
improvement of liver histology assessed as Non-alcoholic steatohepatitis score (NAS score) in patients treated with sleeve gastrectomy
