RESUMO

OBJECTIVES: To describe skin involvement (SI) in patients with systemic lupus erythematosus (SLE) at onset and during follow-up of the disease and to determine factors associated with SI at lupus diagnosis. MATERIALS AND METHODS: Retrospective, observational, and descriptive study, from a single centre in patients diagnosed with SLE (ACR 1982-97 or SLICC 2012 criteria). The modified Gilliam classification for SI was used. Descriptive statistics and bivariate and multivariate analysis were performed to evaluate the factors associated with SI at diagnosis of the disease. RESULTS: 149 patients were included, 91.3% women with a median age at diagnosis of 33 years. SI at onset of the disease occurred in 125 patients (83.9%), followed by joint involvement in 120 cases (80.5%). Non-specific skin lesions were more frequent than specific lesions, 92.8% versus 66.4%, respectively. In the bivariate analysis, a longer delay to diagnosis, the presence of joint involvement, a lower presence of thrombocytopenia, and a higher SLEDAI-2K score were associated with the presence of SI at onset of the disease. In the multivariate analysis, the variable that remained independently associated was joint involvement (OR 2.8%-95% CI 1.1-7.5, p: .04). During follow-up, 4/24 patients who had not presented SI at diagnosis and 51/125 patients who had, had at least one new skin flare (range: 1-5 outbreaks). CONCLUSIONS: Our study demonstrates the high frequency of skin involvement in SLE, both diagnostically and evolutionarily, and confirms previously reported data regarding the existence of a skin-articular phenotype.

RESUMO

Introducción: el lupus es una enfermedad compleja y varias veces de difícil abordaje. Alcanzar la remisión es uno de los objetivos, incorporando opciones terapéuticas. Objetivos: describir las características generales de los pacientes según el estado de la enfermedad y el uso de belimumab. Materiales y métodos: estudio de corte transversal, registro RELESSAR. Se definió el estado de la enfermedad como: remisión: SLEDAI=0 y sin corticoides; baja actividad de la enfermedad: SLEDAI >0 y ≤4 y sin corticoides; control no óptimo: SLEDAI >4 y cualquier dosis de corticoides. Resultados: se incluyeron 1.277 pacientes, 23,4% en remisión, 12,6% en baja actividad y 63,8% con control no óptimo. En este último grupo eran más jóvenes y con menor duración de la enfermedad; presentaban mayores índices de actividad y cronicidad, y mayor empleo de inmunosupresores. Solo el 22,3% de los pacientes con criterio potencial de uso de belimumab (lupus eritematoso sistémico activo a pesar del tratamiento estándar) lo recibía en ese momento. Las variables asociadas a hospitalizaciones fueron: terapia con corticoides, ciclofosfamida y mayor SLICC. Conclusiones: se refleja la complejidad del manejo de estos pacientes y se visualizan aspectos estructurales como la desigualdad. El uso del belimumab resultaría beneficioso en los pacientes seleccionados.


Introduction: lupus is a complex disease and often difficult to approach. Achieving remission is one of the objectives, incorporating therapeutic options. Objectives: to describe the characteristics of the patients and the use of belimumab, according to the status of the disease. Materials and methods: cross-sectional study. Patients of the RELESSAR registry. Stratification: Remission: SLEDAI=0 and without corticosteroids. Low disease activity SLEDAI> 0 and ≤4 and without corticosteroids and non-optimal control: SLEDAI> 4 and any dose of corticosteroids. Results: a total of 1,277 patients were included, 23.4% in remission, 12.6% in low disease activity and 63.8% in non-optimal control. The last group was younger and had a shorter duration of the disease. They had higher activity and chronicity indices and greater use of immunosuppressants. Only 22.3% of the patients with potential criteria for the use of belimumab (activity disease despite standard treatment) were receiving it. The variables associated with hospitalizations were: corticosteroids, cyclophosphamide and higher SLICC. Those associated with severe infection: mycophenolate mofetil, azathioprine, corticosteroids, and higher SLICC. Conclusions: the complexity of the management of these patients is reflected, visualizing structural aspects such as inequality. The use of belimumab could be beneficial in selected patients.

RESUMO

Introducción: Diversas entidades clínicas, como enfermedades autoinmunes, infecciones, neoplasias y fármacos pueden manifestarse con lesiones vasculíticas en la piel. Debido a la heterogeneidad de las causas, suelen representar un desafío diagnóstico. El objetivo de este estudio es describir la etiología de las vasculitis cutáneas (VC) y evaluar las características clínicas, histológicas y de laboratorio halladas en estos pacientes. Material y métodos: Se realizó un estudio retrospectivo con revisión de historias clínicas de pacientes mayores de 16 años con VC por diagnóstico clínico y/o histológico evaluados en el período 2010-2018. Resultados: Se incluyeron 74 pacientes. El 69% son mujeres con una edad media al diagnóstico de 41 años (DE 16.5, rango 16-75). Las causas más frecuentes asociadas a las VC fueron las enfermedades autoinmunes (EAI) en un 50% de los pacientes evaluados. En el 29.7% de los casos no pudo identificarse una causa subyacente. En el 2.7% de los casos se asoció a neoplasias, otro 2.7% a fármacos y un 12% a otras etiologías. El 76% de los pacientes presentaron formas clínicas no severas, predominando la púrpura palpable en el 65% de los casos. Entre los pacientes biopsiados, el 76% fueron vasculitis leucocitoclásticas (VLC). Como manifestaciones extracutáneas asociadas, predominó el compromiso articular (43,2%). En las vasculitis asociadas a EAI, el 33 % presentó compromiso renal, en tanto que éste no se observó en ninguno de los pacientes con vasculitis idiopáticas. El 78% de los pacientes recibieron glucocorticoides sistémicos. Conclusión: En nuestro centro, la etiología más común de VC fue la asociada a EAI. La mayoría de los pacientes eran mujeres. Clínicamente predominaron las manifestaciones cutáneas no severas y la VLC fue el hallazgo más frecuente en las biopsias.


Background: Various clinical entities, such as autoimmune diseases, infections, neoplasms and drugs can manifest with vasculitic lesions on the skin. Due to the heterogeneity of causes, they often represent a diagnostic challenge. The aim of this study is to describe the etiology of cutaneous vasculitis (CV) and to assess the clinical, histological and laboratory characteristics found in these patients. Material and methods: A retrospective study was carried out with a review of the medical records of patients over 16 years old with CV by clinical and/or histological diagnosis evaluated in the period 2010-2018. Results: 74 patients were included. 69% are women with a mean age at diagnosis of 41 years (SD 16.5, range 16-75). The most frequent causes associated with CVs were autoimmune diseases (AID) in 50% of the patients evaluated. In 29.7% of the cases, an underlying cause could not be identified. In 2.7% of the cases it was associated with neoplasms, another 2.7% with drugs, and 12% with other etiologies. 76% of the patients presented non-severe clinical forms, with palpable purpura predominant in 65% of the cases. Among the biopsied patients, 76% were leukocytoclastic vasculitis (LCV). As associated extracutaneous manifestations, joint involvement predominated (43.2%). In vasculitis associated with AID, 33% presented renal involvement, while this was not observed in any of the patients with idiopathic vasculitis. 78% of the patients received systemic glucocorticoids. Conclusion: In our center, the most common etiology of CV was associated with AID. Most of the patients were women. Clinically, non-severe skin manifestations predominated and VLC was the most frequent finding in biopsies.

RESUMO

Presentamos los casos clínicos de tres pacientes adultos jóvenes de origen boliviano, que fueron hospitalizados en salas de clínica médica de un hospital de tercer nivel por manifestaciones de la vía aérea superior y lesiones de las estructuras de la línea media. Reumatología evaluó la posibilidad del diagnóstico de Vasculitis asociada a ANCA, la cual es un diagnóstico diferencial de la entidad conocida como "lesión destructiva de la línea media". En todos los casos se arribó al diagnóstico definitivo de Linfoma T luego de un exhaustivo estudio histopatológico.


We present clinical cases of three Bolivian young adults who were hospitalized in the medical clinic rooms of a third level hospital for upper airway manifestation and lesions of the midline structures. Rheumatology service evaluated the diagnosis of ANCA associated Vasculitis, which is a differential diagnosis of the entity known as midline destructive lesion. In all cases, the final diagnosis of T lymphoma was reached after an exhaustive histopathological study.

RESUMO

A case is presented of a protein-losing enteropathy (PLE) as the initial manifestation of systemic lupus erythematosus (SLE) in a 17 year-old female patient, who presented with ascites, edema and hypoalbuminemia. The diagnosis of SLE was based on the presence of: malar rash, oral ulcers, thrombocytopenia, antinuclear antibodies, IgM anticardiolipin antibody, and lupus anticoagulant. Renal and liver diseases were ruled out. The PLE diagnosis was confirmed with fecal alpha 1-antitrypsin clearance. The PLE was refractory to different lines of immunosuppressive agents like glucocorticoids, cyclophosphamide, azathioprine, and cyclosporine, showing a satisfactory and sustained response with rituximab, allowing steroid sparing and long term remission.

RESUMO

Our objective was to analyze the effects of cigarette smoking on disease activity, functional capacity, radiographic damage, serology and presence of extraarticular manifestations in patients with rheumatoid arthritis and undifferentiated arthritis. This is a cross-sectional study of 1,305 patients (729 with rheumatoid arthritis and 576 with undifferentiated arthritis) from CONAART, the Argentine Consortium for Early Arthritis that includes patients older than 16 years with <2 years of disease. Sociodemographic data, clinical characteristics of the disease and smoking history were collected. In patients with rheumatoid arthritis the disease activity score of 28 joints was 5.4 ± 1.3 in current smokers, 5.2 ± 1.4 in former smokers and 5.1 ± 1.4 in never smokers (p = 0.011). The simple erosion narrowing score was higher in current smokers and former smokers than in never smokers (M 14.0, R Q 6.0-21.0; M 15.0, R Q 7.0-24.0; M 10.0, R Q 5.0-17.0; p = 0.006). Current smokers had higher rheumatoid factor titer (M 160.0, R Q 80.0-341.0) than former smokers (M 146.8, R Q 6.03-255.5) and never smokers (M 15.0, R Q 9.0-80.0) (p = 0.004). The variable independently associated with tobacco exposure was simple erosion narrowing score (OR = 1.03, 95 % CI 1.00-1.05; p = 0.012). In patients with undifferentiated arthritis, an association between smoking status and parameters of activity or radiographic damage was not observed. Neither was tobacco exposure related to the presence of extraarticular manifestations or to the degree of disability in any of the two groups of patients. No relation was found between disease activity and severity, and number of packs smoked per year. Tobacco.
