Alto rendimiento clínico entre albuminuria semicuantitativa y proteinuria de 24 horas en pacientes con sospecha de síndrome hipertensivo del embarazo / High clinical performance between semiquantitative albuminuria and 24-hour proteinuria in patients with suspected hypertensive syndrome of pregnancy

ANTECEDENTES: La evaluación precisa de la proteinuria constituye un pilar importante para el diagnóstico del síndrome hipertensivo del embarazo (SHE). El estándar dorado para esta medición es la recolección de orina en 24 horas, pero debido a la duración de la toma de la muestra, alternativas como la albuminuria semicuantitativa se utiliza con mayor frecuencia en los servicios de urgencia de nuestro país. OBJETIVO: Evaluar el rendimiento diagnóstico de la albuminuria semicuantitativa y su asociación con proteinuria de 24 horas en pacientes con SHE. MÉTODOS: Estudio retrospectivo de 145 pacientes con sospecha de SHE atendidas en el Hospital Padre Hurtado, Chile. A todas las pacientes se le realizó albuminuria semicuantitativa (categorizada entre 0+ y 4+) y proteinuria de 24 horas (positivo si >0,3 gramos/24 horas). Se realizó análisis por grupos compuestos de albuminuria semicuantitativa y resultado positivo en proteinuria de 24 horas. RESULTADOS: Se evidenció una sensibilidad de 50%, especificidad de 100%, VPP de 100%, VPN de 65,7%, LR+ de 50 y un LR- de 0,5. CONCLUSIÓN: La albuminuria semicuantitativa ≥2+ muestra una fuerte asociación con proteinuria ≥0,3 g/24 horas y es un método rápido para evaluar SHE.

BACKGROUND: One of the basis for the diagnosis of pregnancy induced hypertension syndrome (PIHS), includes the precise evaluation of proteinuria. The gold standard for its evaluation is the collection of a 24-hour urine specimen, but because it is a slow method, other alternatives, such as semi-quantitative albuminuria have been used more frequently on our emergency rooms. OBJECTIVE: To assess the diagnostic performance of semi-quantitative albuminuria and its association with proteinuria measured in a 24-hour urine specimen collection, in patients with PIHS. METHODS: Retrospective study of 145 patients with clinical suspicion of PIHS who assisted to Hospital Padre Hurtado, Chile. Semi-quantitative albuminuria (categorized as 0 to 4+) and proteinuria measured in a 24-hour urine specimen collection was measured on every patient. Abnormal values of proteinuria were considered when values exceeded 0.3 g/24 hours. Composite outcomes analysis was done between albuminuria groups and positive proteinuria in 24 hrs. RESULTS: Sensibility and specificity of semi-quantitative albuminuria was of 50% and 100%, respectively, with a PPV: 100%, NPV: 65.7%, LR+: 50 and a LR-: 0.5. CONCLUSION: semi-quantitative albuminuria ≥2+ shows a strong association with proteinuria ≥0.3 g/24 hours and it could be used as a fast method to assess PIHS.

Changes of Atrial Natriuretic Peptide and Aldosterone in Pregnancy-induced Hypertension and Normal Pregnancy / 第二军医大学学报

In order to research into the relationship between atrial natriuretic peptide (ANP), aldosterone (Aldo) and pregnancy-induced hypertension (PIH), as well as normal pregnancy, the plasma concentrations of ANP and Aldo from normal pregnant women. PIH patients and their fetuses were measured by radioimmunoassay. It was found that maternal venous Aldo and ANP were higher in normal pregnant women than those in non-pregnant women. The plasma ANP was higher in PIH patients than that in normal pregnant women while plasma Aldo was lower. The plasma concentration of ANP was higher in the fetuses of PIH patients than that in the normal controls, but Aldo was lower. It is concluded that ANP concentration correlates significantly to the severity of PIH, and may be used for an early diagnosis of PIH.
