RESUMO

Introducción: La albuminuria fue ampliamente considerada como el primer signo clínico de la enfermedad renal diabética (DKD), por lo que se ha utilizado tradicionalmente como prueba de detección para DKD. Sin embargo, el aumento de la evidencia ha demostrado que un número importante de pacientes con diabetes mellitus tipo 2 (DM) tenían disminución de la filtración glomerular (TFG), sin albuminuria significativa (DKD sin albuminuria (NA-DKD). El objetivo de este estudio fue determinar la prevalencia y las características demográficas y clínicas de los pacientes con NA-DKD. Métodos: Este fue un estudio retrospectivo de un año que incluyó a 146 diabéticos tipo 2 con TFG<75ml/min seguidos en el departamento de diabetes. Los pacientes fueron divididos en 2 grupos de acuerdo a su estado de ACR NA-DKD y DKD albuminúrica (A-DKD). Resultados: De los 146 pacientes incluidos en el estudio, 53,4% tienen A-DKD y 46,6% tienen a NA-DKD. En comparación con los pacientes con A-DKD, aquellos con NA-DKD eran más propensos a ser de mayor edad (p=0,021), a ser mujeres (p=0,045) y tenían una TFG menor (p=0,004), datos confirmados en el análisis multivariante. El índice de masa corporal, el control metabólico de la DM, la duración del diagnóstico de DM y la prevalencia de síndrome metabólico no fueron diferentes entre los grupos. Conclusiones: La mayoría de los pacientes con DKD presentan albuminuria, pero una proporción significativa tiene un fenotipo de no albuminuria (46,6% en esta población). Estos pacientes presentan características clínicas diferentes, lo que podría tener relevancia en la proyección, el pronóstico o implicaciones terapéuticas (AU)


Background: Albuminuria was widely considered as the first clinical sign of diabetic kidney disease (DKD), which is why it has traditionally been used as a screening test for DKD. However, increasing evidence has shown that a significant number of type 2 diabetes mellitus (DM) patients have a decreased glomerular filtration rate (GFR) without significant albuminuria, known as non-albuminuric DKD (NA-DKD). The aim of this study was to determine the prevalence and the demographic and clinical characteristics of patients with NA-DKD. Methods: This was a 1-year retrospective study that included 146 type 2 diabetic patients with GFR<75mL/min followed-up in a diabetes outpatient department. Patients were divided into two groups according to their ACR status - NA-DKD and albuminuric DKD (A-DKD). Results: Of the 146 patients included in the study, 53.4% had A-DKD and 46.6% had NA-DKD. According to the multivariable analysis performed, patients with NA-DKD tended to be older (p=0.021), female (p=0.045) and with a lower GFR (p=0.004) than A-DKD patients. There was no difference between the groups in terms of body mass index, metabolic control of DM, duration of DM diagnosis and prevalence of metabolic syndrome. Conclusions: The majority of patients with DKD had albuminuria, but a significant proportion had a non-albuminuric phenotype (46.6% in this population). These patients exhibit distinct clinical features that could have screening, therapeutic and prognosis implications (AU)

RESUMO

Dermatomyositis is rare during the reproductive period, but when it does occur, most cases have been reported from the viewpoint of the obstetric management of high-risk pregnancy. In return, there is little information concerning the contribution of pregnancy to the development and course of dermatomyositis. We describe a patient with dermatomyositis that presented after the delivery of a healthy infant. This case, with support from a literature review, suggests that pregnancy could be a trigger or contributor for the development of dermatomyositis.
