RESUMEN
Resumen OBJETIVO: Determinar la correlación entre las concentraciones de ácido úrico y creatinina en pacientes con preeclampsia severa para conocer su utilidad clínica. MATERIALES Y MÉTODOS: Estudio retrospectivo, transversal y analítico al que se incluyeron pacientes con preeclampsia severa. A la admisión al estudio se registraron las concentraciones sanguíneas de ácido úrico y creatinina para calcular la correlación de las medias generales y por categorías. Se utilizó estadística descriptiva, prueba t de Student, IC95% y coeficiente de correlación de Pearson con el programa estadístico SPSS versión 20. RESULTADOS: Se estudiaron 100 pacientes con preeclampsia severa. La media ge-neral de ácido úrico fue de 5.52 ± 1.43 mg/dL; 85% tuvieron hiperuricemia y 17% hiperuricemia extrema. La media general de creatinina fue de 0.77 ± 0.25 mg/dL; 18% resultaron con hiperazoemia y 14% con hiperazoemia extrema. CONCLUSIONES: El ácido úrico y la creatinina tuvieron correlaciones positivas: a mayor hiperuricemia mayor deterioro de la función renal. Ambos pueden ser marcadores complementarios útiles para identificar la lesión renal aguda en la preeclampsia severa.
ABSTRACT
Abstract OBJECTIVE: To determine the correlation of uric acid and creatinine in pregnant patients with severe preeclampsia to identify its clinical utility. MATERIAL AND METHOD: cross- sectional study that included 100 pregnant patients with severe preeclampsia. Blood levels of uric acid and creatinine were recorded upon admission to calculate the correlation of the general means and by categories. (Normal uric acid ≤ 4 mg/dL, hyperuricemia > 4 mg/dL and extreme hyperuricemia ≥7 mg/dL vs normal creatinine ≤ 0.9 mg/dL, hyperazotemia > 0.9 mg/dL and extreme hiperazoemia ≥ 1.1 mg/dL). Descriptive statistics, Student's T- test, Confidence inter-vals (CI) and Pearson's correlation coefficient were used with the statistical program SPSS version 20. RESULTS: 100 patients with severe preeclampsia were studied. The general average of uric acid was 5.52 ± 1.43 mg / dL; 85% had hyperuricemia and 17% extreme hy-peruricemia. The general average of creatinine was 0.77 ± 0.25 mg / dL; 18% resulted with hyperazotemia and 14% with extreme azotemia. CONCLUSIONS: Uric acid and creatinine showed positive correlations. It was found that the greater the degree of hyperuricemia, the greater the deterioration of renal function. Both markers can be complemented to identify acute kidney injury in severe preeclampsia.
