Séamus Hussey

Principal Investigator and Consultant Gastroenterologist

A graduate of UCC, Dr Hussey initially trained at Our Lady’s Children’s Hospital, Crumlin, before completing a fellowship in academic paediatric gastroenterology, hepatology and nutrition at the Hospital for Sick Children (Sickkids), Toronto, Canada.

His research fellowship was in cell biology and immunology at the University of Toronto, focusing on the role of autophagy in bacterial infections, including Helicobacter pylori, and in the pathogenesis of inflammatory bowel disease. He was appointed as a consultant gastroenterologist at Our Lady’s Children’s Hospital, Crumlin, in 2010, an honorary senior lecturer at the RCSI in 2016, and associate clinical professor at UCD in 2016.

Dr Hussey leads the DOCHAS research programme, which has been funded by, and based at, the NCRC since its inception. DOCHAS, the Irish word for hope, is Ireland’s first prospective study of paediatric inflammatory bowel diseases. This research platform enables clinical and translational research into the causes and outcomes of paediatric IBD. Since its launch in 2012, DOCHAS has enabled development of successful collaborations with local, national and international clinicians and scientists. Currently there are over 10 active clinical and translational research projects that have evolved from DOCHAS.

Principal Investigator and Consultant Gastroenterologist

Dr. Sarah Cooper
Position: Clinical Research Coordinator

Sarah coordinates our clinical research studies including recruitment and follow up of patients, liaises with PIs and collaborators and oversees the work of our research assistants.

Dr. Lenin Ekpotu
Position: Clinical Research Assistant

Lenin coordinates the recruitment and follow up of patients involved in the Modified-EEN study and provides support to other studies and assistance to those undertaking research in our department.

Ilona Csizmadia
Position: Clinical Research Assistant

Ilona is a qualified Dietitian and holds an MSc in Nutrition Science. Her core focus is the recruitment and follow up of patients involved in the DOCHAS study as well as the collection of biological samples for the DOCHAS biobank.

Determinants and Outcomes in Children and Adolescents with IBD (DOCHAS)

A prospective study of the causes and outcomes of paediatric inflammatory bowel disease in Ireland. Patients are followed from the time of referral throughout their patient journey. Information regarding their disease subtype, their treatment and their clinical outcomes over time is recorded. Biological samples (taken pre-treatment) are vital for the translational studies that stem from DOCHAS.

Paediatric Cancer and Mortality Study

This is a prospective European study of the incidence of deaths and malignancies in patients up to age 26 years who were diagnosed with IBD before age 18 years.

Allergy in IBD study

This project stems from the DÓCHAS study, and will ascertain the prevalence of food related allergies in patients with IBD.

Oral microbiome in IBD

This study looks at the baseline oral microbial flora in treatment naïve patients with IBD and will track potential changes in the oral flora over time.

The role of IL-36a in ulcerative colitis

This is a collaborative study, led by Dr Pat Walsh, which seeks to elucidate the role of the IL-36 protein family in the cause and outcome of ulcerative colitis.

Role of Nox4 in Crohn disease

This is a collaborative study with Profs Ulla Knaus and Billy Bourke that seeks to explore the potential role of Nox4 in fibrostenotic Crohn disease.
