Vishal Patel is a Consultant Hepatologist & Endoscopist at the Liver Unit, King's College Hospital, focusing on Advanced Chronic Liver Disease (ACLD) and portal hypertension. He is a Principal Investigator and Group Lead for Microbiome in ACLD at the Roger Williams Institute of Hepatology, and Honorary Reader in Hepatology within the School of Immunology & Microbial Sciences at King's College London. 


Dr Patel’s conducts clinical translational research with his lab group investigating two core themes:

  1. The microbiome and antimicrobial resistance in the oral-gut-liver axis in ACLD (continuing work from his PhD) and harnessing novel sequencing techniques to enhance rapid infection diagnostics
  2. Circulating cell-free DNA in chronic liver failure syndromes, linked to mechanistic profiling in different stages of ACLD and sepsis and how this interacts with coagulation pathways and immune dysfunction

His group’s work aims to better understand underlying disease mechanisms in this condition, and to identify potential targets for therapy to develop new treatments.


  1. In-depth shotgun metagenomic analysis of the oral and gut microbiome identifies striking overlaps in microbial community structure, virulence factors and antimicrobial resistance based on severity and stage of cirrhosis
  2. Evaluating the role of circulating cell-free DNA-mediated coagulation dysfunction, systemic inflammation, and organ injury in chronic liver failure syndromes
  3. Development and evaluation of point-of-care diagnostics utilising clinical metagenomic sequencing for rapid pathogen and antimicrobial resistance detection in decompensated cirrhosis and acute-on-chronic liver failure
  4. Beta-blockers Or Placebo for Primary Prophylaxis of oesophageal varices (BOPPP Trial). A blinded, UK multi-centre, clinical effectiveness and cost-effectiveness randomised controlled trial (NIHR funded £2.5 million) – Chief Investigator, sponsored by King’s College Hospital
