Objective. Assessment of associations of nailfold videocapillaroscopy (NVC) scleroderma (systemic sclerosis; SSc) (%26quot;early,%26quot; %26quot;active,%26quot; and %26quot;late%26quot;) with novel future severe clinical involvement in 2 independent cohorts. %26lt;br%26gt;Methods. Sixty-six consecutive Belgian and 82 Italian patients with SSc underwent NYC at baseline. Images were blindly assessed and classified into normal, early, active, or late NYC pattern. Clinical evaluation was performed for 9 organ systems (general, peripheral vascular, skin, joint, muscle, gastrointestinal tract, lung, heart, and kidney) according to the Medsger disease severity scale (DSS) at baseline and in the future (18-24 months of followup). Severe clinical involvement was defined as category 2 to 4 per organ of the DSS. Logistic regression analysis (continuous NYC predictor variable) was performed. %26lt;br%26gt;Results. The OR to develop novel future severe organ involvement was stronger according to more severe NVC patterns and similar in both cohorts. In simple logistic regression analysis the OR in the Belgian/Italian cohort was 2.16 (95% CI 1.19-4.47, p = 0.010)/2.33 (95% CI 1.36-4.22, p = 0.002) for the early NYC SSc pattern, 4.68/5.42 for the active pattern, and 10.14/12.63 for the late pattern versus the normal pattern. In multiple logistic regression analysis, adjusting for disease duration, subset, and vasoactive medication, the OR was 2.99 (95% CI 1.31-8.82, p = 0.007)/1.88 (95% CI 1.00-3.71, p = 0.050) for the early NYC SSc pattern, 8.93/3.54 for the active pattern, and 26.69/6.66 for the late pattern versus the normal pattern. %26lt;br%26gt;Conclusion. Capillaroscopy may be predictive of novel future severe organ involvement in SSc, as attested by 2 independent cohorts.
