Orla Killeen

Consultant Adolescent and Paediatric Rheumatologist Associate Clinical Professor UCD

Dr Orla Killeen graduated from University College Ireland, Galway (NUIG) in 1996. She trained in General Paediatrics in Our Lady’s Children’s Hospital, Crumlin, and in Temple Street University Hospital, Dublin, before sub-specialising in Paediatric Rheumatology. She undertook her paediatric rheumatology training at Great Ormond Street Children’s Hospital, London, and went on to complete a Barbara Ansell Fellowship in Paediatric Rheumatology in the Royal Hospital for Sick Children, Glasgow. She was appointed as Ireland’s first Paediatric Rheumatologist in 2004, and has been based at Our Lady’s Children’s Hospital, Crumlin, and St Vincent’s University Hospital, Dublin, since July 2006. She established the National Centre for Paediatric Rheumatology (NCPR) in 2006, providing care for patients with rheumatic and musculoskeletal disorders both on a local and national level. Her areas of interest include care of the Young person/Adolescent Rheumatology focusing in particular on Transition as well as juvenile idiopathic arthritis (JIA), Down’s Arthritis, juvenile dermatomyositis (JDM) and Auto-Inflammatory Syndromes.

Down’s Arthropathy (DA): Clinical Features and Biomarkers of Arthritis in Children with Trisomy 21

Down’s Arthritis (DA) is rarely recognised at onset, and remains under-diagnosed. As a direct consequence, children with DA can present with significant joint damage and disability at diagnosis. This MD project was upgraded to a PhD study in 2015. Initially focused on evaluating the clinical and pathological features of Arthritis in children with Down syndrome, further studies that seek to define the disease in terms of it’s genetic, immunological and histopathological origins are ongoing.

Whole exome mapping of genetic variants linked with the development of chronic recurrent multifocal osteomyelitis (CRMO).

Chronic recurrent multifocal osteomyelitis (CRMO) is an auto-inflammatory condition primarily affecting children, and has an estimated prevalence of 1 per 106 (OMIM 259680). It is characterized by relapsing episodes of localized bone inflammation. We are currently undertaking whole exome sequencing to identify genetic variants associated with CRMO. This data may inform a personalized therapeutic approach based on target therapies leading to reduced inflammatory load and bone damage.

Developing a UK/ROI study of the incidence of JSLE in children and young people and their access to care: a collaborative approach

The incidence of Juvenile-onset Systemic Lupus Erythematosus (JSLE) in the UK is unknown. Furthermore, we do not know how children and young people present and when and where they access care. This study aims to determine the incidence of JSLE and begin to understand how and where we look after children and young people with JSLE in the UK and Ireland.
