Resumen
Objetivo: evaluar la frecuencia de acidosis metabólica en la enfermedad renal crónica (ERC) y su impacto en la evolución.
Material y método: se realizó un estudio retrospectivo de pacientes del Programa de Salud Renal del Uruguay (octubre de 2004 a octubre de 2011) con dos controles separados por seis o más meses y al menos un dato de bicarbonatemia. Se analizaron: creatininemia, proteinuria, bicarbonatemia venosa y tratamiento alcalinizante. Se consideró evento final el ingreso a diálisis o trasplante y/o fallecimiento. Análisis estadístico: test de t, chi2, ANOVA, Kaplan-Meier y análisis multivariado de Cox (significativo p < 0,05).
Resultados: se analizaron 921 pacientes con al menos un dato de bicarbonatemia (232 pacientes con dos o más datos). La creatininemia fue mayor en las nefropatías túbulo intersticiales y en los grupos con bicarbonatemia menor a 23 mEq/l (acidosis) o mayor a 32 mEq/l versus grupo intermedio. La bicarbonatemia fue menor en los estadios IV-V versus I-II de ERC. En estadios I-II, la bicarbonatemia fue menor si tenía proteinuria. Recibían alcalinizantes al inicio 7,3% y al final 31%. En el grupo con acidosis, el aumento de creatininemia/año (n = 232) fue mayor y la sobrevida (combinada) fue menor. Los niveles de bicarbonatemia, creatininemia y proteinuria se correlacionaron independientemente con el evento final combinado (ingreso a tratamiento de sustitución renal /muerte).
Conclusiones: la acidosis metabólica se puede observar desde estadios iniciales de ERC y es un factor independiente de progresión y muerte, por lo que se recomienda su detección precoz y corrección.
