Perttu Arkkila

Perttu Arkkila is a Professor at the University of Helsinki's Department of Medicine within the Clinicum Faculty of Medicine. His research focuses on gastroenterology, particularly inflammatory bowel disease (IBD), microbiota transplantation, and clinical pharmacology. He leads studies on Fecal Microbiota Transplantation (FMT) efficacy, antibiotic impacts on gut microbiota, and biologic therapies for IBD. His work bridges clinical practice and translational research, addressing therapeutic innovations and diagnostic advancements in gastrointestinal disorders.

Research interests include IBD pathogenesis, microbiota dysbiosis, and novel treatments for chronic gastrointestinal conditions. He explores drug effects on gut physiology (e.g., tenofovir formulations) and evaluates biomarkers for disease activity assessment. His studies also investigate cross-disciplinary topics like gut-brain interactions in neurodegenerative diseases and pancreatic cyst diagnostics using next-generation sequencing.

Recent publications emphasize FMT applications in Parkinson’s disease, comparative efficacy of anti-IBD biologics (infliximab vs. vedolizumab), and antibiotic resistance dynamics in stool donors. He contributes to clinical trial design for obesity interventions and advanced fibrosis risk in nonalcoholic liver disease. His work highlights translational research impacting patient care through microbiota modulation and precision medicine approaches.
