Maternal and umbilical cord procalcitonin, high-sensitivity C-reactive protein, and interleukin-6 levels in preeclamptic and normotensive patients: A cross-sectional study.

OBJECTIVES: To report maternal and umbilical vein levels of procalcitonin (PCT) in patients with preeclampsia (PE) compared to controls. As secondary aims, we measured high-sensitivity C-reactive protein (hs-CRP), and interleukin-6 (IL-6). Moreover, correlation analyses were performed between the inflammatory biomarkers and mean arterial pressure (MAP). STUDY DESIGN: This was a single center, cross-sectional study. MAIN OUTCOME MEASURES: After Institutional Review Board approval and written informed consent, patients with or without PE were enrolled. PCT, hs-CRP, and IL-6 levels were compared between groups using multiple linear regression models. We calculated the adjusted ratios of geometric means (aRGM) for the comparison of patients with and without PE. Correlation analysis between the inflammatory biomarkers and MAP was performed using Spearman's method. RESULTS: A total of 156 participants were enrolled, yielding 156 venous blood samples and umbilical venous blood samples. Seventy-six patients were in the PE group, and 80 patients were in the control group. Maternal plasma and serum concentrations of PCT (aRGM 3.35 (95% confidence interval [CI]: 2.26, 4.95; p < 0.001)), hs-CRP (aRGM 1.85 (95% CI: 1.30, 2.63; p = 0.003)), and IL-6 (aRGM 1.49 (95% CI: 1.08, 2.04; p = 0.045)) were higher in the PE group. In umbilical venous samples, the concentrations of PCT (aRGM 2.54 (95% CI: 1.46, 4.44; p = 0.003)) and hs-CRP (aRGM 1.45 (95% CI: 1.13, 1.87; p = 0.012)) in the PE group were higher than the controls. No difference in umbilical venous IL-6 concentrations were detected between PE vs. control groups (aRGM 1.46; 95% CI: 1.07, 1.98; p = 0.051). There was positive correlation for both PCT and hs-CRP with MAP in maternal and umbilical venous samples. However, there was no correlation between IL and 6 and MAP in maternal or umbilical venous samples. CONCLUSIONS: PCT levels were elevated in maternal and umbilical venous samples of patients with PE, and correlated with disease severity.

Takayasu arteritis a cause of hypertensive disorder of pregnancy: a case report.

BACKGROUND: Takayasu arteritis is a rare, chronic, granulomatous systemic vasculitis of unknown etiology and a few cases have been reported in pregnancy. In pregnancies concomitant with Takayasu arteritis or after diagnosis, Takayasu arteritis negatively affects pregnancy by increasing 13-fold the odds of complications such as hypertensive disorders. The best recommendations in this scenario are still to be made. CASE PRESENTATION: We present a case of 21-year-old, gravid 1, Mexican woman of Mestizo descent with chronic hypertension diagnosed since she was 15-years old who presented severe hypertension during pregnancy (early second trimester); the diagnosis of hypertensive disorder of pregnancy was ruled out requiring first-line and second-line antihypertensive therapy without serious associated maternal or fetal morbidity. CONCLUSIONS: Takayasu arteritis and pregnancy play an important role in maternal and fetal outcomes. Efforts should be made to further investigate the Takayasu arteritis diagnosis in pregnant women with refractory hypertension.

Uroflujometría: límites de normalidad en una muestra de población / Urinary flow rate measurement (urofluwometry) normality limits in a poblation sample

Durante un período de tres meses se midieron los flujos de una muestra de población voluntaria normal. Se reunieron 112 adultos, los cuales se repartieron por grupos de edad y sexo. Los resultados de las mediciones de flujo máximo promedio fueron, en los varones menores de 40 años de edad, de 31.3 (+ - 4.8), en los de 40 a 60 años, de 27.3 (+ - 5.3), y en los mayores de 60 años, de 25.0 ( + - 6.1). En las mujeres menores de 50 años de edad estos valores fueron de 32.2 ( + - 5.3), y en las mayores de 50 años de 27.6 ( + - 6.3) ml/s. Estos resultados se compraron con los comunicados por Abrams y, en la población que motivó este estudio, se obtuvieron valores más elevados (promedios) de 5.4 para el sexo masculino y de 2.6 ml/s para el sexo femenino. Es posible que en la diferencia observada tengan importancia factores ambientales, raciales o de ambos tipos. En la literatura no se encontraron informes de los valores normales de la uroflujometría en la población de México ni en la de Iberoamérica. Los valores que se toman como límites de normalidad proceden de estudios realizados en el extranjero.
