Abstract
Introduction

Capillaroscopy is a non-invasive tool used to evaluate microcirculation and determine whether a Raynaud's phenomenon is primary or secondary. Capillaroscopic changes are well-described in systemic sclerosis; however, these alterations have been less studied in other autoimmune diseases.

Objective

The aim of this study is to determine videocapillaroscopic alterations in lupus, and its association with clinical manifestations.

Materials and methods

A cross-sectional study with analytical intention was performed. Videocapillaroscopy and medical evaluations were performed on 76 patients with lupus, according to SLICC 2012 classificatory criteria, from January to June 2019. Chi2, Fisher, and Mann–Whitney U tests were used to evaluate association, and the prevalence ratios (PR) were determined. A multivariate analysis was performed.

Results

Seventy-one (93.4%) of the patients were female with a median age of 33.5 years (interquartile range [IQR]: 27–44.8); the median lupus duration was 84 months (IQR: 30–168). The main clinical manifestations were articular, cutaneous, hematological, and Raynaud's phenomenon. A non-specific pattern was found in 43 patients (56.6%), and a systemic sclerosis-like pattern was found in 7 patients (9.2%). In bivariate and multivariate analyses, Raynaud episodes occurring more than once a week (PR 1.24; 95% CI: 1.13–1.33) were more frequent in patients with a sclerosis-like or a non-specific pattern.

Conclusion

Lupus patients frequently have videocapillaroscopic alterations with non-specific and systemic sclerosis like patterns, which are more common in patients with Raynaud's phenomenon that occurs more than once a week. Due to the study's design, it is impossible to determine causality.

Resumen
Introducción

La capilaroscopia es una herramienta no invasiva utilizada para evaluar la microcirculación y determinar si el fenómeno de Raynaud es primario o secundario. Los cambios capilaroscópicos están bien descritos en la esclerosis sistémica, sin embargo, estas alteraciones se han estudiado menos en otras enfermedades autoinmunes.

Objetivo

El objetivo de este estudio es determinar las alteraciones videocapilaroscópicas en el lupus y su asociación con manifestaciones clínicas.

Materiales y métodos

Estudio transversal con intención analítica. Se realizó videocapilaroscopia y evaluación médica a 76 pacientes con lupus de enero a junio del 2019. Se utilizaron las pruebas U de Mann-Whitney, Chi cuadrado y Fisher para evaluar la asociación, y se determinaron las razones de prevalencia (PR). Se realizó un análisis multivariado.

Resultados

Setenta y un (93,4%) pacientes eran mujeres, con edad media de 33,5 años (rango intercuartil [RIQ]: 27-44,8); la mediana de duración del lupus fue de 84 meses (RIQ: 30-168). Las principales manifestaciones clínicas fueron articulares, cutáneas, hematológicas y el fenómeno de Raynaud. Se encontró un patrón no específico en 43 pacientes (56,6%) y un patrón similar a la esclerosis sistémica en siete pacientes (9,2%). En los análisis bivariados y multivariados, los episodios de Raynaud que ocurren más de una vez por semana (PR 1,24; IC 95%: 1,13-1,33) fueron más frecuentes en pacientes con un patrón de esclerosis no específico.

Conclusión

Los pacientes con lupus con frecuencia tienen alteraciones videocapilaroscópicas con patrones no específicos, que son más comunes en pacientes con fenómeno de Raynaud que ocurre más de una vez por semana.
