Digital Public Defence: Nina Paulshus Sundlisæter Nina Paulshus Sundlisæter at Institute of Clinical Medicine will be defending the thesis “Remission in early rheumatoid arthritis - Predictors, definitions and treatment” for the degree of PhD (Philosophiae Doctor).

The University of Oslo arranges digital public defences this semester, thus the disputation will be held as a video conference over Zoom.

The public defence will follow regular procedure as far as possible, hence it will be open to the public and the audience can ask ex auditorio questions when invited to do so.

In this thesis Nina Paulshus Sundlisæter assessed achievement and prediction of different remission definitions in rheumatoid arthritis (RA). She also studied the association between definitions of remission and long-term outcomes, and how to treat RA patients in sustained remission. The thesis is based on data from two randomized controlled trials, ARCTIC and ARCTIC REWIND.

Paulshus Sundlisæter showed that sustained remission was achievable in RA patients treated according to current recommendations, even if negative prognostic factors were present. Less joint tenderness and short symptom duration at time of disease-modifying antirheumatic drug (DMARD) initiation predicted remission. Attainment of ACR/EULAR Boolean remission had the strongest association with both a good radiographic and functional outcome.

Patients in sustained remission on conventional synthetic DMARDs were randomized to either continued stable therapy or half-dose. Patients in the stable group experienced less flares and less frequent radiographic joint damage progression the next year. Thus, continued stable therapy should be the preferred choice for RA patients in sustained remission.
