Effects of Probiotic on Inflammation and Microbiota in Patients With NASH

Study Overview
=================
Brief Summary
-----------------
Individuals with clinically identified non-alcoholic fatty liver disease will undergo baseline evaluation of IL-17 and other inflammatory markers as well as microbiome determination. The probiotic formulation VSL#3 450 Billion CFU twice daily will be administered for 8 weeks and the determination of Il-17 and microbiome will be repeated. Each subject will serve as his or her own control.

Detailed Description
-----------------
This study is designed as a prospective trial of the effects of probiotic on inflammatory and stool profiles in patients with NAFLD. These patients are actively followed by the Division of Hepatology. They will have confirmed normal liver function tests and absence of hepatitis C virus in order to be eligible for this study. Eligible subjects will be identified within the outpatient setting of the Division of Hepatology of the Northwell Health System. Division of Hepatology 400 Community Drive Manhasset, NY 11030 516-562-4281 Candidate subjects will be identified by investigators as a part of their typical work flow. Subjects will be evaluated according to inclusion and exclusion criteria presented. Eligible patients will be provided with a packet containing study information and informed consent documents. Should a patient remain interested in study participation, informed consent will be obtained. Financial compensation will not be provided to subjects. Forty patients with NAFLD will be enrolled. Following enrollment and informed consent, subjects will undergo the following assessments: Medical History Questionnaire Current Medication List Blood and stool samples will be obtained prior to study initiation and again after 8 weeks of exposure. Protocol for biological sample collection: Whole Blood Collection - Venipuncture will be performed under standard conditions. Three heparinized tubes will be obtained which each tube containing approximately 10 cc of whole blood Samples will be de-identified. Peripheral Blood Cells will be isolated from whole blood samples according to standard protocols. Serum cytokine levels, including IL-10 and IL-17, will be assessed. Stool Collection - Patients will be provided with stool collection kits. Samples will be de-identified. Stool samples will be preserved in a -20 degree freezer in the Division of Infectious Diseases.
