Capillaroscopy in the daily clinic of the pediatric rheumatologist.

In the last decade, nailfold capillaroscopy is finding its way to the daily clinic of (pediatric) rheumatologist. This review will provide the necessary knowledge for the clinician performing this easy and non-invasive examination in children. In the first part, background information on type of capillaroscopy device and standardized (internationally validated) interpretations for the different capillary variables compared to healthy pediatric controls will be provided. The second part focusses on capillary changes that are observed in Raynaud's phenomenon with follow-up recommendations. This part will also cover capillaroscopy findings in juvenile systemic sclerosis, childhood-onset systemic lupus erythematosus, juvenile dermatomyositis and -mixed connective tissue disease, as well as correlations with disease severity. Lastly, a research agenda shows the current gaps we have in knowledge in this niche of nailfold capillaroscopy in pediatric connective tissue diseases.
