RESUMO
The objective was to analyse the levels of uric acid in the hypertensive disorders of pregnancy. The research involves the study of 137 patients that suffered any hypertensive disease associated with pregnancy, hospitalized on the Luis Castelazo Ayala Hospital. The patients were classified according to the ACOG. The levels of uric acid observed were measured and compared against one control group and between them. The levels of uric acid observed in any hypertensive state of pregnancy are superior to the ones observed in then control group. On patients with chronical hypertension complicated with preeclampsia, the levels of uric acid were above the levels observed on patients with chronic hypertension itself. It is not known with certainty, but some authors think that the problem es rather tubular than glomerular. There is not an exact explanation about uric acid's depuration. Nevertheless, the common characteristic is a reduction of renal perfusion. Uric acid is related with the degree of severity. Moreover, uric acid is a good indicator for the detection of hypertensive states of pregnancy.
