Correlación del ácido úrico con el grosor de la íntima media de la carótida en adolescentes con obesidad / Correlation of uric acid with carotid intima media thickness in obese adolescents

Introducción: la obesidad en la población pediátrica es un problema de salud pública. Se ha demostrado la correlación del ácido úrico y el grosor de la íntima media de la carótida en adultos. Objetivo: identificar la correlación del ácido úrico y el grosor de la íntima media de la carótida en adolescentes con obesidad. Material y métodos: se realizó un estudio observacional, transversal. Se incluyeron pacientes de diez a 16 años con diagnóstico de obesidad. Se determinó ácido úrico, perfil de lípidos y grosor de la íntima media carotidea. En el análisis estadístico, se correlacionó el grosor de la íntima media carotídea con los niveles de ácido úrico a través del coeficiente de correlación de Spearman. Resultados: se incluyeron 169 adolescentes con una mediana para la edad de 13 años, sin predominio de sexo. Se identificó una correlación positiva del ácido úrico con el grosor de la íntima media carotídea (r = 0,242, p = 0,001). Al estratificarse de acuerdo con el sexo, no hubo correlación en las mujeres (r = -0,187, p = 0,074), mientras que en los hombres aumentó (r = 0,36, p = 0,001) y por estadio puberal, los adolescentes varones púberes tuvieron una correlación positiva (p = 0,384, p = 0,002). Conclusión: se identificó una correlación positiva débil entre el grosor de la íntima de la carótida y el ácido úrico en adolescentes con obesidad. (AU)

Introduction: obesity in the pediatric population is a public health problem. The correlation of uric acid and carotid intima media thickness in adults has been demonstrated.Objective: to identify the correlation of uric acid and carotid intima media thickness in adolescents with obesity.Material and methods: an observational, cross-sectional study was carried out. Patients aged ten to 16 years with a diagnosis of obesity were included. Uric acid, lipid profile and carotid intima media thickness were determined. In relation to the statistical analysis, carotid intima media thickness was correlated with uric acid levels through Spearman's correlation coefficient. Results: one hundred and sixty-nine adolescents were included with a median age of 13 years, without predominance of sex. A positive correlation of uric acid with carotid intima media thickness was identified (r = 0.242, p = 0.001). When stratified according to sex, there was no correlation in women (r = -0.187, p = 0.074), while in men it increased (r = 0.36, p = 0.001) and by pubertal stage, pubertal male adolescents had a positive correlation (p = 0.384, p = 0.002).Conclusion: a weak positive correlation was identified between carotid intimal thickness and uric acid in obese adolescents.

Cardiovascular Risk Factors and Carotid Intima-Media Thickness in a Colombian Population With Psoriasis. / Factores de riesgo cardiovascular y grosor de la íntima media carotídea en una población colombiana con psoriasis.

BACKGROUND AND OBJECTIVES: Psoriasis is now known to have a clear association with metabolic syndrome and its components. The aim of our study was to determine the prevalence of cardiovascular risk factors (CVRFs) and increased carotid intima-media thickness in psoriasis patients seen in the dermatology department of a quaternary hospital. MATERIAL AND METHODS: This was a descriptive cross-sectional study of psoriasis patients aged over 18 years seen in the dermatology department of Hospital de San José in Bogota, Colombia, between March and August, 2015. Directed medical history and physical examination were performed to detect CVRFs, laboratory studies to exclude metabolic syndrome, and ultrasound examination to measure carotid intima-media thickness. RESULTS: Forty patients with psoriasis were included in the study. The prevalence of the distinct CVRFs was 35% for systemic hypertension, 17.5% for dyslipidemia, 17.5% for smoking, and 10% for type 2 diabetes mellitus. A history of acute myocardial infarction was detected in 12.5% of patients. Metabolic syndrome was found in 20 patients (50%), and blood biochemistry revealed dyslipidemia in 32 patients (80%). Based on the Framingham score, the cardiovascular risk was low in 11 patients (31.4%), intermediate in 22 (62.8%), and high in 2 (5.7%). Mean (SD) carotid intima-media thickness was 0.7 (0.12) mm, with thickening observed in 6 patients (15%). CONCLUSIONS: This study provides evidence of the high prevalence of CVRFs in psoriasis patients and indicates the need for strict clinical control to monitor cardiovascular risk in this population.

La proteína C reactiva se asocia al grosor de la íntima media de la arteria carótida en pacientes con hipercolesterolemia aislada / C-reactive protein is asociated to carotid intima media thickness in patients with isolated hypercholesterolemia

Estudios han comprobado que concentraciones elevadas de colesterol total a expensas del colesterol LDL y marcadores de inflamación, se relacionan con ateroesclerosis subclínica. El objetivo del estudio fue determinar la asociación de los niveles séricos de la proteína C reactiva ultrasensible (PCRus) con la medida del grosor de la íntima media carotídea (GIMCa) en pacientes hipercolesterolémicos. La investigación fue descriptiva, transversal e incluyó 100 pacientes divididos en grupo control (normocolesterolémico) y grupo estudio (hipercolesterolémico). No se observaron diferencias en edad y distribución por género entre los grupos. El índice de masa corporal, circunferencia abdominal, colesterol total y sus fracciones, GIMCa y PCRus se encontraron significativamente elevados en el grupo estudio. Sólo en el grupo hipercolesterolémico, el GIMCa se asoció significativamente con la PCRus. En el grupo estudio, el GIMCa promedio se elevó a través de los cuartiles de PCRus, adquiriendo su máximo valor en el cuarto cuartil. El análisis de regresión lineal múltiple identificó al colesterol unido a la LDLc y a la PCRus como predictores del GIMCa sólo en el grupo estudio. La evidencia encontrada apoya otros datos que apuntan a que no sólo el colesterol unido a la LDL sino también la PCRus podría ser un importante factor de cambios ateroscleróticos tempranos en la arteria carótida de pacientes con hipercolesterolemia aislada.

Studies have shown that high concentrations of total cholesterol at the expense of LDL cholesterol and markers of inflammation are linked with subclinical atherosclerosis. This study was aimed to associate the carotid intima media thickness (IMT) and high-sensitivity C-reactive protein (hs-CRP) in patients with isolated hypercholesterolemia. The investigation was descriptive, transverse and included 100 patients divided into a control group (normocholesterolemic) and a study group (hypercholesterolemic). There were no significant differences in age and gender distribution among the groups. The body mass index, waist circumference, total cholesterol and its fractions, IMT and hs-CRP were significantly elevated in the study group. Only in the hypercholesterolemic group, the IMT was significantly associated with hsCRP. In the study group, the mean IMT rose by quartiles of hs-CRP, reaching its highest level in the fourth quartile. The multiple linear regression analysis identified LDL cholesterol and hs-CRP as predictors of IMT only in the study group. The findings support other data suggesting that not only the LDL cholesterol but also hs-CRP could be an important factor for early atherosclerotic changes in the carotid artery of patients with isolated hypercholesterolemia.
