INTRODUCTION: Glomerulopathy is a complication of congenital heart disease patients. The risk of developing renal impairment is particularly high in cyanotic patients.
OBJECTIVE: The aim of this study was to determine the prevalence of renal dysfunction and microalbumiuria in adult cyanotic and non cyanotic congenital heart disease patients.
METHODS: Fourteen cyanotic and 22 noncyanotic congenital heart disease patients were studied in the Adult Congenital Heart Disease Unit at the Complejo Hospitalario Universitario Insular-Materno Infantil. Demographic characteristics, complete blood count, and 24-hour urianalysis were obtained, including abdominal ultrasound in those with cyanosis.
RESULTS: No differences were seen between age (years) (27.4 +/- 8.2; 26.4 +/- 8.3; P = .71), sex, size, weight, or glomerular filtration rate (mL/min/1.73 m(2)) (81.1 +/- 22.9 vs. 84.9 +/- 9.2, P = .482) between cyanotic and noncyanotic patients. However, Eisenmenger patients had significantly impaired renal function when compared with noncyanotic patients (73.0 +/- 17.3 vs. 84.9 +/- 9.2 mL/min/1.73 m(2), P = .023). Significant differences were obtained in oxygen saturation (%) (83.8 +/- 5.8 vs. 97.8 +/- 0.8; P = .000), hematocrit (%) (59.3 +/- 8.1 vs. 40.9 +/- 8.5; P = .000), platelets (10(3)/microL) (161.5 +/- 70.5 vs. 277.9 +/- 57.6; P = .000), serum uric acid (mg/dL) (7.5 +/- 2.3 vs. 5.6 +/- 1.5; P = .008) and microalbuminuria (mg/24 hours) (12.8 [0, 700.2] vs. 2.4 [0, 18.9]; P = .000) between cyanotic and noncyanotic patients. Five cyanotic patients (35.7%) had microalbuminuria (>30 mg/24 hours) and three of them (21.4%) proteinuria (>1 g/24 hours). No significant differences were seen between serum and urine parameters between cyanotic patients who had microalbuminuria (>30 mg/24 hours) and those cyanotic patients who did not have it (<30 mg/24 hours).
CONCLUSIONS: Renal impairment is frequently seen in congenital heart disease patients, being associated occasionally with proteinuria and microalbuminuria in cyanotic ones.
