Results and prognosis of kidney transplantation in lupus nephritis: Experience of an Argentine center.

INTRODUCTION: Although RT has improved the survival of the population with ESRD due to all causes, renal outcomes in SLE are controversial. The objective of this study is to describe the characteristics and evolution of the patients and the kidney transplant in LN, and compare it with patients transplanted for other causes. MATERIALS AND METHODS: Retrospective, observational, analytical, single-center study in which records of patients undergoing nephrotransplantation for LN were analyzed. They were compared with a group of patients transplanted at the same center for other causes of ESRD. RESULTS: 41 patients with kidney transplant due to SLE and 89 transplanted due to other causes of ESRD were registered. Graft loss occurred in 12 (29.26%) patients with LN and 34 (38.2%) patients in the comparison group (p = .428). Only one case (4.8%) presented reactivation of the LN in the graft, without graft loss. Median graft survival was 73.1 months in the LN group and 66.3 months in the comparison group (p = .221). A total of 8 (19.5%) patients with LN and 11 (12.4%) without LN died (p = .42), with infections being the main cause in both groups. There were no statistically significant differences between groups in graft and patient survival. In a sub-analysis of 28 patients with LN with aPL study, 4 thrombotic events were observed, in 3 different patients, in the aPL-positive group. There were no statistically significant differences in terms of causes of graft loss and graft survival (positive aFL 75.7 months vs negative aFL 72.7 months, p= .96). There were also no differences in mortality between the groups (p = .61). CONCLUSION: Patients transplanted for LN did not differ from the control population in terms of graft and patient survival. Infections were the main cause of death, so prophylaxis and vaccination continue to be a fundamental pillar in the prevention of infections in immunocompromised patients.

Manifestaciones cutáneas en pacientes con lupus eritematoso sistémico: formas al inicio de la enfermedad y durante el seguimiento. Análisis retrospectivo / Cutaneous manifestations in patients with systemic lupus erythematosus: Forms at the beginning of the disease and during follow-up. Retrospective analysis

Objetivo: Describir el compromiso cutáneo (CC) en pacientes con lupus eritematoso sistémico (LES) al inicio de la enfermedad y durante el seguimiento. Determinar factores asociados a dicho compromiso al comienzo de la enfermedad. Materiales y métodos: Estudio retrospectivo, observacional y descriptivo, de centro único, en pacientes con diagnóstico de LES (ACR97 o SLICC2012). Se utilizó la clasificación de Gilliam modificada para el CC. Se realizó estadística descriptiva y análisis bivariado y multivariado para evaluar los factores asociados al compromiso cutáneo. Resultados: Se incluyeron 149 pacientes (91,3% mujeres) con una mediana de edad al diagnóstico de 33años. El CC al inicio de la enfermedad ocurrió en 125 pacientes (83,9%), seguido por compromiso articular en 120 (80,5%). Las lesiones no específicas fueron más frecuentes que las específicas: 92,8% versus 66,4%, respectivamente. En el análisis bivariado, la mayor demora al diagnóstico, la presencia de compromiso articular, la menor presencia de trombocitopenia y la mayor puntuación de SLEDAI-2K se asociaron con la presencia de CC al inicio de la enfermedad. En el análisis multivariado, la variable que se mantuvo asociada de manera independiente fue el compromiso articular (OR: 2,8; IC95%: 1,1-7,5; p=0,04). Durante el seguimiento, 4/24 pacientes que no habían presentado CC al diagnóstico y 51/125 pacientes que sí lo presentaron tuvieron al menos un nuevo episodio cutáneo (rango: 1-5 brotes). Conclusiones: Nuestro estudio demuestra la alta frecuencia de pacientes que presentan compromiso cutáneo en el LES, tanto en el diagnóstico como evolutivamente, y confirma los datos reportados previamente en cuanto a la existencia de un fenotipo cutáneo-articular.(AU)

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 (ACR1982-97 or SLICC2012 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: A total of 149 patients were included, 91.3% women, with a median age at diagnosis of 33years. 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.(AU)

Lesiones destructivas de la línea media: diagnóstico diferencial con Vasculitis Asociada a ANCA / Destructive lesions of midline: differential diagnosis with ANCA-associated Vasculitis

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.
