Risk for renal injury in diabetic hypertensive patients. The physiologic basis for blood pressure control.
In determining a therapeutic approach to coexistent adult-onset (type II) diabetes and hypertension in patients who are middle-aged, special attention must be given to the pathophysiology of the hypertensive disease and how it affects the kidneys. Diabetes and hypertension potentiate renal damage, which clearly leads to a reduced life span and increased morbidity. Nonpharmacologic measures (eg, exercise, weight control, glycemic control, protein-restricted diet) and pharmacologic approaches need to be combined so as to control systemic blood pressure yet maintain adequate renal perfusion. Clearly, preexisting accentuated vascular reactivity to vasoconstrictive growth factors in diabetic patients stimulates maladaptive compensatory responses in the kidney. This precipitates greater renal injury superimposed on the relative risk of the hypertension-diabetes combination itself.
