RESUMO

The outcome of the SARS-CoV-2 (COVID-19) infection fundamentally affects the lung field, causing acute respiratory distress syndrome (ARDS). This process is an inflammatory picture, involving an NLRP3 inflamosome-triggered cytokine storm, the main player in alveolar destruction. IL-1 beta stands out among the cytokines that are triggered in this picture. Anakinra is a potent biological drug, capable of blocking this IL-1ß. We propose its use in controlling ARDS secondary to COVID-19 infection.

RESUMO

BACKGROUND: Systemic lupus erythematosus (SLE) is a genetically complex rheumatic disease characterized by heterogeneous clinical manifestations of unknown etiology. Recent studies have suggested the existence of a genetic basis for SLE heterogeneity. The objective of the present study was to identify new genetic variation associated with the clinically relevant phenotypes in SLE. METHODS: A two-stage pathway-based approach was used to identify the genetic variation associated with the main clinical phenotypes in SLE. In the discovery stage, 482 SLE patients were genotyped using Illumina Human Quad610 microarrays. Association between 798 reference genetic pathways from the Molecular Signatures Database and 11 SLE phenotypes was tested using the set-based method implemented in PLINK software. Pathways significantly associated after multiple test correction were subsequently tested for replication in an independent cohort of 425 SLE patients. Using an in silico approach, we analyzed the functional effects of common SLE therapies on the replicated genetic pathways. The association of known SLE risk variants with the development of the clinical phenotypes was also analyzed. RESULTS: In the discovery stage, we found a significant association between the vascular endothelial growth factor (VEGF) pathway and oral ulceration (P value for false discovery rate (P FDR) < 0.05), and between the negative regulation signaling pathway of retinoic acid inducible gene-I/melanoma differentiation associated gene 5 and the production of antinuclear antibodies (P FDR < 0.05). In the replication stage, we validated the association between the VEGF pathway and oral ulceration. Therapies commonly used to treat mucocutaneous phenotypes in SLE were found to strongly influence VEGF pathway gene expression (P = 4.60e-4 to 5.38e-14). Analysis of known SLE risk loci identified a strong association between PTPN22 and the risk of hematologic disorder and with the development of antinuclear antibodies. CONCLUSIONS: The present study has identified VEGF genetic pathway association with the risk of oral ulceration in SLE. New therapies targeting the VEGF pathway could be more effective in reducing the severity of this phenotype. These findings represent a first step towards the understanding of the genetic basis of phenotype heterogeneity in SLE.

RESUMO

OBJECTIVES: To identify patterns (clusters) of damage manifestations within a large cohort of SLE patients and evaluate the potential association of these clusters with a higher risk of mortality. METHODS: This is a multicentre, descriptive, cross-sectional study of a cohort of 3656 SLE patients from the Spanish Society of Rheumatology Lupus Registry. Organ damage was ascertained using the Systemic Lupus International Collaborating Clinics Damage Index. Using cluster analysis, groups of patients with similar patterns of damage manifestations were identified. Then, overall clusters were compared as well as the subgroup of patients within every cluster with disease duration shorter than 5 years. RESULTS: Three damage clusters were identified. Cluster 1 (80.6% of patients) presented a lower amount of individuals with damage (23.2 vs 100% in clusters 2 and 3, P < 0.001). Cluster 2 (11.4% of patients) was characterized by musculoskeletal damage in all patients. Cluster 3 (8.0% of patients) was the only group with cardiovascular damage, and this was present in all patients. The overall mortality rate of patients in clusters 2 and 3 was higher than that in cluster 1 (P < 0.001 for both comparisons) and in patients with disease duration shorter than 5 years as well. CONCLUSION: In a large cohort of SLE patients, cardiovascular and musculoskeletal damage manifestations were the two dominant forms of damage to sort patients into clinically meaningful clusters. Both in early and late stages of the disease, there was a significant association of these clusters with an increased risk of mortality. Physicians should pay special attention to the early prevention of damage in these two systems.

RESUMO

Las manifestaciones oculares en el lupus eritematoso sistémico (LES) son relativamente frecuentes, con mayor prevalencia de la queratoconjuntivitis seca. Sin embargo, la aparición de exoftalmos unilateral secundario a pseudotumor orbitario en pacientes con LES es extremadamente rara 1–7, y en ocasiones puede presentarse refractaria al tratamiento farmacológico convencional (glucocorticoides e inmunosupresores). A continuación presentamos el caso de una paciente con LES y pseudotumor orbitario refractario a tratamiento con ciclofosfamida y excelente respuesta clínica con desaparición de la clínica oftalmológica tras el inicio de la terapia con rituximab(1gx2), eficacia mantenida tras la infusión de dos ciclos completos sin incidencias (AU)


Ocular manifestations in Systemic Lupus Erythematosus(SLE)are relatively frequent, with a major prevalence of the Keratoconjunctivitis sicca. Nevertheless, the appearance of unilateral exophthalmos secondary to orbital pseudotumor in patients with SLE is extremely rare 1–7, and on occasion it can be refractory to conventional pharmacological treatment(glucocorticoids and immunosuppressants). We present the case of a patient with SLE and orbital pseudotumor refractory to treatment with Cyclophosphamide(CF) and an excellent clinical response, with disappearance of the ophthalmological condition after the beginning of the rapy with Rituximab (1gx2), continuing after the infusion of two complete cycles without incidents (AU)

RESUMO

Objetivo Servir de referencia para reumatólogos e implicados en el tratamiento de la artritis reumatoide que vayan a utilizar o consideren la utilización de terapias biológicas en su manejo. Métodos Las recomendaciones se emitieron siguiendo la metodología de grupos nominales y basadas en revisiones sistemáticas. El nivel de evidencia y el grado de recomendación se clasificaron según el modelo del Center for Evidence Based Medicine de Oxford y el grado de acuerdo se extrajo por técnica Delphi. Resultados Se realizan recomendaciones sobre el uso de los siete agentes biológicos disponibles para la artritis reumatoide en la actualidad en nuestro país. El objetivo del tratamiento es lograr la remisión de la enfermedad lo más precozmente posible. Se revisan las indicaciones y matizaciones del uso de terapias biológicas y cuál debe ser la evaluación previa y la vigilancia del paciente con estos fármacos. Conclusiones Se presentan las actualizaciones a las recomendaciones SER para el uso de terapias biológicas en pacientes con artritis reumatoide(AU)

RESUMO

La afección renal es infrecuente en la esclerosis sistémica, a diferencia de otras colagenosis. La aparición de síndrome nefrótico se ha relacionado con el uso de fármacos, especialmente la D-penicilamina, o raramente como manifestación de amiloidosis secundaria, bastante infrecuente en la esclerosis sistémica. Presentamos un caso de síndrome nefrótico en una paciente con esclerosis sistémica, producido por una glomerulonefritis membranosa, descrito de forma excepcional en la literatura (AU)


The renal affectation is infrequent in scleroderma, unlike other collagen diseases. The appearance of nephrotic syndrome has been related to the drug use, specially the D-penicilamine, or rarely as a manifestation of secondary amilodosis, quite infrequent in scleroderma. We report a case of nephrotic syndrome in a patient with systemic scleroderma, produced by a membranous glomerulonephritis, exceptionally described in literature (AU)
