MS Self - A study on the validity, sensitivity and user experience of new mobile selfmonitoring devices voor people with Relapsing Remitting Multiple Sclerosis

Technological developments such as smartphones and consumer wearable devices (i.e. the Fitbit) provide novel opportunities for selfmonitoring of people with chronic diseases.Here, we aim to gain insight into the use of these technologies for studies…

Auto-antibody sequencing in patients with autoimmune myasthenia gravis and pemphigus

The main objective of this study is to characterize the pathogenic B cells and the auto-antibodies that are responsible for causing the myasthenic or pemphigus syndromes. The secondary objective is to generate recombinant antibodies based on the…

Differences in unaffected skin of patients with hidradenitis suppurativa compared with healthy controls.

To compare the microbiome, histology, immunohistochemistry and gene expression profile of healthy skin from the axillae or groin of 10 healthy volunteers with uninvolved axilla or groin skin from age, gender, body mass index, and smoking status…

The DRAIHA study: Data Registry of AutoImmune Hemolytic Anemia, to improve diagnostic testing for the development of personalized treatment protocols in AIHA patients

Primary objective1. The primary aim of the study is to answer the question whether specification of a positive direct antiglobulin test and/or red blood cell autoantibody specification is correlated with the clinical course in patients with AIHA.…

Immunological assessment of SARS-CoV-2 in IENIMINI cohort individuals with influenza like symptoms.

Primary objective: To evaluate, in a cohort of non-tested individuals who reported flu-like symptoms during the COVID19 epidemic in the Netherlands (March-November), the seroprevalence of COVID19 in patients with an IMID, with or without…

Prediction aided tapering in reumatoid arthritis patients treated with biologicals

To assess the effect of adding a tapering decision aid on a dynamic flare prediction model to disease-activity-guided dose optimisation (DGDO) on the incidence of flares and medication use.

PsA digital phenotyping and inflammation drivers study

Primary objectives:  To develop and internally validate a novel and interpretable machine learning model for detecting flare in PsA patients using integrated accelerometer data, keystroke dynamics and screen time metrics (i.e., digital…
