Background Capillaroscopy findings can be qualitatively described as: normal, microangiopathy (non-specific abnormalities) or scleroderma pattern (1). Capillary abnormalities, described in varying prevalence in patients with systemic lupus erythematosus (SLE), are mainly described as microangiopathy (2–4)

Objectives To describe capillary characteristics in a cross-sectional cohort of patients with childhood-onset SLE (cSLE) by quantitative and qualitative assessment

Methods Nailfold videocapillaroscopy (NVC) was performed in cSLE-patients (onset <18 years) with a x200 magnification lens (Optilia). The following capillaroscopic characteristics were evaluated per millimeter: density (compared to mean density known for age, sex and ethnicity) (5), number of abnormal shapes (as defined by the EULAR study group on microcirculation in Rheumatic Diseases (6)), giant capillaries (defined as apical diameter >50 mcm), maximum apical diameter (dilatations defined as apical diameter 20–50mcm) and microbleedings (large hemorrhages and small multiple point-shaped hemorrhages surrounding the capillary loop [image])

Results 4063 capillaries from 20 patients with cSLE, were analyzed. All patients showed capillary abnormalities, 15% (n=3) showed a scleroderma-pattern. A lower mean density (mean 6.7, range 1.9–9.5) was seen in 55% (n=11), multiple (>8 per patient) abnormal shapes in 60% (n=12), apical dilatations in 90% (n=18). Total count of large/small point shaped hemorrhages was 109/855, with a mean of 0.2/1.6 per analyzed image/per patient. These were detected in 85/85% of patients (n=17)

Conclusions In this pilot (n=20) of cSLE patients, all showed capillary abnormalities. The most striking finding was the point-shaped bleeding surrounding the capillary, observed in 85% (n=17) of our patients. Prospective longitudinal cohort studies in children through the EULAR study group on microcirculation in Rheumatic diseases will elucidate whether specific findings can be found in child rheumatic diseases
