ABSTRACT
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.

INTRODUCTION: In the GLADEL cohort, the bullous lupus (BSLE) prevalence was 0.41%. However, literature on pediatric BSLE is scarce. This study described the clinical, histological, and immunological characteristics and the treatment response in a series of children with BSLE as the first clinical manifestation of pediatric SLE. METHODS: The clinical, histological, and immunological characteristics of a series of 5 cases of BSLE between 2010-2019 from two reference centers in Colombia were analyzed. RESULTS: All cases had bullous lesions that resolved with residual hypopigmentation. One had a focal seizure, and another arthritis with thrombocytopenia. Two had transient proteinuria with normal urinalysis. Anti-nuclear antibody titers ranged from 1:160 to 1:2560, and four were anti-dsDNA (+). Five patients had anti-RNP antibodies, and four anti-Sm antibodies. All had low C3, and 80% low C4 counts; 80% had erythrocyte sedimentation rate (ESR) ≥20 mm/hour and 60% had C-reactive protein (CRP) ≥0.5 mg/dL. All patients responded to glucocorticoids and dapsone. Histology reports and direct immunofluorescence (DIF) test showed subepidermal blisters with neutrophils in the papillary dermis and linear deposits of Igs/complement proteins in 80% of the skin biopsies. IgG/IgM was present in 5 samples. IgA was positive in 60% and C3 in 80%. CONCLUSIONS: In this pediatric series, BSLE tends to have a monophasic behavior associated with neuropsychiatric, skeletal, and hematological involvement in 40% of the patients, and with good prognosis.

RESUMEN Los nódulos reumatoides pulmonares son una manifestación extra-articular infrecuente de la artritis reumatoide (AR). Su estudio es importante porque su presentación clínica e imagenológica puede confundirse con tuberculosis, infecciones fúngicas y neoplasias pulmonares. Producen pocos síntomas y pueden conducir a complicaciones fatales como neumotórax, fístula broncopleural y sobreinfección con formación de abscesos. La confirmación diagnóstica fundamental descansa en el estudio histopatológico, dado que es un diagnóstico de exclusión. El tratamiento precisa seguimiento clínico ya que no hay una terapia dirigida utilizándose en casos severos rituximab y tocilizumab. En general, su aparición tiende a empobrecer el pronóstico de los pacientes con AR.
ABSTRACT Pulmonary rheumatoid nodules are an uncommon extra-articular manifestation of rheumatoid arthritis (RA). Its study is important because the clinical and imaging presentation could be confused with tuberculosis, fungal infections, and/or lung neoplasms. Pulmonary nodules produce few symptoms and can lead to fatal complications such as pneumothorax, bronchopleural fistula, and a superinfection with abscess formation. The fundamental diagnostic confirmation is the histopathological study because it is an exclusion diagnosis. The treatment needs clinical follow-up as there is no targeted therapy, with Rituximab and Tocilizumab being used in severe cases. In general, their appearance tends to lead to a poorer prognosis of patients with RA.
