 PARADISE: PersonAlisation of RelApse risk in autoimmune DISEase
From
1/4/23
To
31/3/26
Summary
What is the problem PARADISE wants to address? In Europe, 30 million people suffer from an autoimmune disease; it is the third largest cause of morbidity and mortality, after cancer and heart disease, in industrialised countries. At the individual level, the impact of suffering can be immense, at the societal level, a significant health and economic burden. Autoimmune disease affects 10% of adults, most of whom are women, and two of the top five medications with the highest cost globally are used to keep these recurring conditions in remission. These medications suppress the immune system, leaving the patient exposed to increased infection and cancer risk. The general requirement for such treatments, and their side effects, has been raised as a key target for research by the PARADISE consortium patient groups. What is the aim of PARADISE? PARADISE delivers a practical response to this challenge. We aim to develop a personalised prediction tool that accurately defines the patient"s risk of disease recurrence so that medication doses can be tailored and, in some cases, stopped safely. We use systemic vasculitis as a typical autoimmune disease, bringing together clinical, biomarker and smartphone derived wellbeing data to inform predictive algorithms underpinning a physician tool. What exactly will PARADISE do? PARADISE will combine and analyse multi-source heterogeneous data, create a prediction model, and implement it as a physician-facing tool to inform ANCA-associated vasculitis care, ready for a future clinical trial. Such artificial intelligence (AI) applications are coming under intense EU scrutiny, so we will co-develop an "AI transparency notice", which will make explicit and explainable the PARADISE tool clinical outputs.

 FAIRVASC " building registry interoperability to inform clinical care
From
1/6/20
To
1/11/23
Summary
FAIRVASC is a research project of the European Vasculitis Society (EUVAS) and RITA European Reference Network, bringing together leading scientists, clinicians and patient organisations. The FAIRVASC consortium is made up of 10 partners who represent all of these areas of patient care, also substantial support from VIFOR PHARMA should be acknowledged. There are many important gaps in our knowledge about why and how vasculitis occurs, why some people seem to be more susceptible than others, how the disease process acts inside the body and whether different kinds of vasculitis should be treated in different ways. As the condition is rare, there are relatively few patients in any one European country. We, therefore, need to analyse data at a European level so that we have enough patient data to discover these important missing facts. FAIRVASC will use semantic-web technologies to link vasculitis registries across Europe into a `single European dataset", and thus open the door to new research into these challenging diseases. The programme will ensure that all included registries are FAIR and that the infrastructure developed is aligned with developments in the European Joint Programme. In FAIRVASC, this large new European resource will be analysed to identify features (clinical and physical characteristics, etc.) that predict how a patient"s illness will develop, and what their major health risks are. These markers can, in the future, be developed into new predictive tools that help doctors to choose the best treatment options for the individual patient. Research into the rare condition " Vasculitis (an acquired, immune mediated inflammatory disease involving blood vessels of many tissues and organs), needs sufficiently large quantities of data to enable well-informed conclusions about treatments and possible cures. It is thus essential to combine the databases of patient registries of several countries to build a dataset of sufficient size to enable meaningful research.

 AVERT: Autoimmunity Relapse Prediction Using Multiple Parallel Data Sources
From
1/2/17
To
1/2/20
Summary
We propose a new way of managing chronic diseases that brings the fields of medicine and data science together. We hypothesise that the interaction between individuals with the relapsing and remitting autoimmune kidney disease ANCA vasculitis, and their environment, can be detected and defined by observing the whole system in action and integrating a wide array of data sources. Collaboration with IBM will allow us to take advantage of recent advances in machine learning technology that allows iterative refinement of algorithms to generate a technology readiness level 3 proof of concept physician tool, to present analysis results in a clinically meaningful way. The ultimate goal of this approach is to define the signature of vasculitis relapse and use this to aid in planning and delivery of optimum immunosuppressive therapy at the level of the patient. To achieve this, we will use advanced data science methodologies and Bayesian statistical techniques to develop a data architecture that curates and combines from four sources: Fixed patient-level factors (HLA-DP phenotype, granular clinical dataset obtained at diagnosis), External medical influences (maintenance immunosuppression, antibiotic prescriptions, Hospital Inpatient Enquiry records), External environmental influences, linked to patient location through time (meteorological data streams, community pathogen patterns: readily available as online data streams) and Direct patient-derived data sources (location, patient-reported quality of life and accelerometer defined activity). We expect a 50% rate of relapse after 5 years in a cohort of patients derived from the Rare Kidney Disease registry; we shall describe for the first time the relapse prodrome and define in great detail the environmental influences linking to this event.

 HELICAL - Health Data Linkage for Clinical Benefit
From
1/1/19
To
31/07/23
Summary
HEalth data LInkage for ClinicAL benefit is a training network comprising 17 academic and 9 non-academic/industry partners for early stage researchers in the field of Healthcare Data Linkage in the GDPR era. European researchers have made leading contributions to the large genomic, transcriptomic and clinical datasets from patients with chronic diseases. Advances in information science provide unprecedented opportunities for using these datasets to elucidate the complex biology of these disorders, its influence by environmental triggers, and to personalise their management. Exploitation of these opportunities is limited by a shortage of researchers with the required informatics skills and knowledge of requisite data protection principles. HELICAL addresses this unmet need by developing a trans-sectoral and interdisciplinary programme with training in analysis of large datasets, using autoimmune vasculitis as a paradigm, as comprehensive biological and clinical datasets are already available. The programme will be delivered through a partnership of Academic and Industry researchers with expertise in basic biomedical research, epidemiology, statistics, machine learning, health data governance and ethics. HELICAL exploits recent advances in data science to link research datasets with longitudinal healthcare records, based on the robust ethical foundation required for linkage studies using near-patient data, to address key experimental questions.

 Urinary sCD163 as a biomarker in crescentic glomerulonephritis
From
1/1/19
To
1/2/20
Summary
This project is focused on development of a novel biomarker test in the diagnosis and monitoring of crescentic glomerulonephritis (CGN), a severe form of inflammatory kidney injury. This test relies upon identification of a single protein in the urine: soluble CD163. This is shed from activated macrophages, the predominant cell in glomerular crescents, which are in direct communication with the urinary space. Extensive experimental work in our laboratory has brought this biomarker to technology readiness level 3. This project will bring it to level 7, laying the foundation for a definitive trial.

President of Ireland Young Researchers Award 2012
I run a translational medicine research programme focused on investigation of pathogenesis and discovery of biomarkers of disease in glomerulonephritis. My principal research interest is in ANCA vasculitis, an autoimmune condition that causes multi-organ failure as a consequence of overwhelming necrotising inflammation affecting small blood vessels. My lab spans cellular immunology in the Trinity Translational Medicine Institute and health data informatics in the ADAPT SFI Centre. We are addressing the following questions: 1. What biomarkers accurately track glomerular inflammation in ANCA vasculitis? 2. What molecular and cellular events lead to myeloid cell dysfunction in ANCA vasculitis? 3. What underpins the large variability in clinical phenotype observed in ANCA associated vasculitis? 4. How can we minimise the adverse events associated with existing immunosuppressive therapies? 5. How do we predict relapse in ANCA vasculitis? This research spans two primary areas: 1. Health data informatics. Massive challenges exist in this area in Ireland, where health data is fragmented and difficult to access. I currently lead a trans-disciplinary "Chronic Disease Informatics Group", which links basic immunology, health informatics and data analytics. The HELICAL (HEalth data LInkage for ClinicAL benefit) MSCA Innovative Training Network explored the impact of health and research data linkage to address complex challenges in autoimmune disease. It was followed by the FAIRVASC (Building registry interoperability to inform clinical care) European Joint Programme for Rare Diseases funded EU consortium, which used a knowledge graph approach to link rare disease registries for the first time into a federated learning platform. We applied semantic web technology to large scale data integration challenges in autoimmune disease, leading to a pipeline for multi-modal algorithm development and linkage to, for example, environmental datasets. This semantic web user interface now runs queries over federated databases containing >5000 patients across Europe and will become part of the rare disease discovery platform under development by the European Joint Programme for Rare Disease. An example of application of this data linkage approach is the discovery that ultraviolet-B radiation exposure is linked to autoimmune disease relapse. 2. Translational immunology of autoimmune disease, specifically the rare immune disorder ANCA vasculitis. A cornerstone of this was creation of a national biobank and registry of patients with this disease (RITA-Ireland registry and biobank), which is now among the most extensive globally. This has provided an unrivalled substrate for biomarker discovery, the most impactful of which is urine sCD163. This translational work extends into study of disease pathogenesis using primary biological samples and data, for example the identification of novel subsets of neutrophils and monocytes in ANCA vasculitis. Linking this with the heath data informatics research, the PARADISE (PersonAlisation of RelApse risk in autoimmune DISEase) ERA-PerMed funded EU consortium is currently driving translational innovation, applying multi-modal deep phenotyping to develop algorithms for individual level prediction of vasculitis relapse. Aligning with the FAIRVASC initiative, I lead a trans-European data linkage infrastructure for ANCA vasculitis, which integrates clinical (from registries), biomarker (proteomic, transcriptomic and genomic) and patient-reported data (from wearable devices) at the level of the individual, supporting multi-modal assessment and personalised medicine.
