December 23, 2010 updated by: Brooke Army Medical Center

Prevalence of Nonalcoholic Fatty Liver Disease and Nonalcoholic Steatohepatitis Utilizing Ultrasound and Percutaneous Liver Biopsy: A Prospective Cohort Study

Prospective determination of the prevalence of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH)in a primary care setting using ultrasound and percutaneous liver biopsy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Detailed Description

Patients between the ages of 18 and 70 years who are eligible for care at Brooke Army Medical Center are considered for enrollment. After obtaining informed consent, a baseline questionnaire is given to patients who present to the Primary Care Clinic for routine clinic visits or during colon cancer screening classes within the Gastroenterology Clinic. The questionnaire includes information about the patient's past medical history to include: known history of chronic liver disease, current medications, current and past alcohol ingestion, dietary habits that included consumption of fructose containing beverages and frequency of fast food visits. Patients are excluded if they are found to have a history of chronic liver disease, HIV, on medications that are associated with a fatty liver, or consumption of more than 20 grams of alcohol per day. Right upper quadrant ultrasound will then be performed to determine if there is evidence of fatty liver disease. All patients with a positive ultrasound for hepatic steatosis are then offered a liver biopsy after obtaining fasting blood work that included a complete blood count, coagulation studies, liver function tests, fasting lipid panel, glucose and insulin. Patients with a negative ultrasound for fatty liver are not referred for liver biopsy and are considered as completed study patients. Serum is also stored for adipokine and cytokine analysis. A study investigator using a 14g Bard Monopty biopsy gun will perform the liver biopsy. A single expert hepatopathologist will review all liver biopsies and utilize the Brunt system (9) for grading and staging of steatohepatitis if present.

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

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients 18 to 70 years of age who have access to care through the Primary Care Clinics or the Gastroenterology Clinic at Brooke Army Medical Center

Description

Inclusion Criteria:

  • Patients 18 to 70 years of age were recruited from the Primary Care Clinics or the Gastroenterology Clinic at Brooke Army Medical Center. After completing a baseline questionnaire, all patients had a right upper quadrant ultrasound. If fatty liver was identified, then laboratory data and a liver biopsy were obtained.

Exclusion Criteria:

  • ETOH consumption over 20 grams/day
  • known fatty liver disease, chronic liver disease, HIV, or medication ingestion associated with fatty liver disease

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
NAFLD/NASH prevalence
Any subject between the ages of 18-70 without known fatty liver disease who meet inclusion criteria
Procedure: possible liver biopsy and serum collection
All patients with a positive ultrasound for hepatic steatosis offered a liver biopsy after obtaining fasting blood work that included a complete blood count, coagulation studies, liver function tests, fasting lipid panel, glucose and insulin. Patients with a negative ultrasound for fatty liver are not referred for liver biopsy and are considered as completed study patients. Serum is also stored for adipokine and cytokine analysis. A study investigator using a 14g Bard Monopty biopsy gun performs the liver biopsy.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2007

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
