ABSTRACT
OBJECTIVES: To standardly assess and describe nailfold videocapillaroscopy (NVC) assessment in children and adolescents with juvenile rheumatic and musculoskeletal diseases (jRMD) vs healthy controls (HCs). MATERIAL AND METHODS: In consecutive jRMD children and matched HCs from 13 centres worldwide, 16 NVC images per patient were acquired locally and read centrally per international consensus standard evaluation of the EULAR Study Group on Microcirculation in Rheumatic Diseases. A total of 95 patients with JIA, 22 with JDM, 20 with childhood-onset SLE (cSLE), 13 with juvenile SSc (jSSc), 21 with localized scleroderma (lSc), 18 with MCTD and 20 with primary RP (PRP) were included. NVC differences between juvenile subgroups and HCs were calculated through multivariable regression analysis. RESULTS: A total of 6474 images were assessed from 413 subjects (mean age 12.1 years, 70.9% female). The quantitative NVC characteristics were significantly lower or higher in the following subgroups compared with HCs: for density: lower in jSSc, JDM, MCTD, cSLE and lSc; for dilations: higher in jSSc, MCTD and JDM; for abnormal shapes: higher in JDM and MCTD; for haemorrhages: higher in jSSc, MCTD, JDM and cSLE. The qualitative NVC assessment of JIA, lSc and PRP did not differ from HCs, whereas the cSLE and jSSc, MCTD, JDM and cSLE subgroups showed more non-specific and scleroderma patterns, respectively. CONCLUSIONS: This analysis resulted from a pioneering registry of NVC in jRMD. The NVC assessment in jRMD differed significantly from HCs. Future prospective follow-up will further elucidate the role of NVC in jRMD.

INTRODUCTION: Having reliable predictive models of prognosis/the risk of infection in systemic lupus erythematosus (SLE) patients would allow this problem to be addressed on an individual basis to study and implement possible preventive or therapeutic interventions. OBJECTIVE: To identify and analyze all predictive models of prognosis/the risk of infection in patients with SLE that exist in medical literature. METHODS: A structured search in PubMed, Embase, and LILACS databases was carried out until May 9, 2020. In addition, a search for abstracts in the American Congress of Rheumatology (ACR) and European League Against Rheumatism (EULAR) annual meetings' archives published over the past eight years was also conducted. Studies on developing, validating or updating predictive prognostic models carried out in patients with SLE, in which the outcome to be predicted is some type of infection, that were generated in any clinical context and with any time horizon were included. There were no restrictions on language, date, or status of the publication. To carry out the systematic review, the CHARMS (Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies) guideline recommendations were followed. The PROBAST tool (A Tool to Assess the Risk of Bias and Applicability of Prediction Model Studies) was used to assess the risk of bias and the applicability of each model. RESULTS: We identified four models of infection prognosis in patients with SLE. Mostly, there were very few events per candidate predictor. In addition, to construct the models, an initial selection was made based on univariate analyses with no contraction of the estimated coefficients being carried out. This suggests that the proposed models have a high probability of overfitting and being optimistic. CONCLUSIONS: To date, very few prognostic models have been published on the infection of SLE patients. These models are very heterogeneous and are rated as having a high risk of bias and methodological weaknesses. Despite the widespread recognition of the frequency and severity of infections in SLE patients, there is no reliable predictive prognostic model that facilitates the study and implementation of personalized preventive or therapeutic measures.Protocol registration number: PROSPERO CRD42020171638.

RESUMEN Objetivo: La actividad y el riesgo de recaída de la arteritis de Takayasu son bajos durante la gestación. Hasta el 40% de las pacientes puede tener desenlaces obstétricos desfavorables, por lo que es importante conocer su comportamiento clínico. Describimos las características clínicas y el desenlace obstétrico de gestantes con arteritis de Takayasu atendidas en un hospital de alta complejidad. Materiales y métodos: Evaluación retrospectiva de historias clínicas de gestantes con arteritis de Takayasu atendidas en el Hospital Universitario San Vicente Fundación de Medellín, Colombia, entre 2011 y 2018. Resultados: Se incluyó en el estudio a 6 pacientes con mediana de edad al diagnóstico de 17,5 arios (RI 9,25), al parto de 24 arios (RI 8,25) y con una duración de la enfermedad de 5,5 arios (RI 10,5). Del total, 3 pacientes tenían compromiso aórtico extenso; al parto, 3 pacientes esta ban activas y requirieron inmunosupresores, 5 tenían hipertensión arterial, una desarrolló preeclampsia en el segundo trimestre, una tenía insuficiencia mitral y tricuspídea grave con disminución de la fracción de eyección del ventrículo izquierdo; 2 tenían aneurismas (arte ria subclavia izquierda y aorta ascendente). Ningún embarazo resultó en aborto ni parto pretérmino; hubo 2 óbitos fetales, uno por restricción del crecimiento intrauterino e insuficiencia placentaria, y otro de etiología desconocida; ambas pacientes con actividad de la enfermedad, afección aórtica extensa e hipertensión arterial. Fueron por cesárea 5 par tos por indicación materna; no hubo disección aórtica, rotura aneurismática ni hemorragia cerebral. Conclusión: Las pacientes con enfermedad activa y afección aórtica extensa presentaron resultados obstétricos desfavorables, lo que indica que el inadecuado control de la vasculitis genera mayores complicaciones materno-fetales.
ABSTRACT Objective: The activity and risk of relapse of Takayasu's arteritis are low during pregnancy. Up to 40% of patients may have unfavorable obstetric outcomes therefore it is important to know their clinical behavior. We describe the clinical characteristics and obstetric outcome of pregnant women with Takayasu arteritis treated in a hospital of high complexity. Materials and methods: A retrospective evaluation of medical records of pregnant patients with Takayasu's arteritis treated at Hospital Universitario San Vicente Fundación in Medellin, Colombia between 2011 and 2018. Results: Six patients with a median age at diagnosis 17.5 (RI 9.25) years, at delivery 24 (RI 8.25) years, disease duration 5.5 (RI 10.5) years. Three patients had extensive aortic involvement; at delivery, 3 patients were active and required immunosuppressants, 5 had high blood pres sure, one developed preeclampsia in the second trimester, one had severe mitral and tricus pid insufficiency with a decreased ejection fraction of the left ventricle; 2 had aneurysms (left subclavian artery and ascending aorta). No pregnancy resulted in abortion or preterm birth; there were 2 fetal deaths, one due to intrauterine growth restriction and placental insuffi ciency and another of unknown etiology; both patients with disease activity, extensive aortic condition, and arterial hypertension. Five deliveries were by cesarean section by maternal indication; there was no aortic dissection, aneurysmal rupture or cerebral hemorrhage. Conclusion: Patients with active disease and extensive aortic compromise presented unfa vorable obstetric results, suggesting that inadequate control of vasculitis leads to greater maternal-fetal complications.
