[Ischemic disease of the kidneys and combined chronic nephropaties: clinical and prognostic features].
OBJECTIVE
To characterize clinical features and course of ischemic renal disease (IRD) combined with other chronic nephropathies.


METHODS
We examined 102 patients with IRD treated in the E. M. Tareev clinic of the I. M. Sechenov Moscow Medical Academy in 2001-2006. We made a general clinical examination, clinical and biochemical blood tests. Glomerular filtration rate (GFR) was calculated according to Cockroft-Gault formula. Arterial hypertension was assessed according to ESH.


RESULTS
IRD associated with other chronic nephropathies was detected in 35 (34.3%) patients. Association of atherosclerotic stenosis of the renal arteries (ASRA) with diabetic, urate nephropathies was diagnosed in 9 and 8 patients, respectively; chronic pyelonephritis--in 7 cases, chronic glomerulonephritis--in 4 patients. The age of IRD patients associated with other chronic renal diseases was younger than of those with isolated IRD. Systolic arterial pressure was significantly higher in patients with isolated IRD, body mass index and total cholesterol--in the groups of IRD association with other chronic nephropathies. Aggravation of renal failure in patients with CRD association with other chronic nephropathies was provoked by ACE inhibitors and blockers of angiotensin II receptors. Revascularization of the kidneys in IRD associated with other chronic nephropathies leads to significant lowering of systolic blood pressure and stabilization of creatininemia.


CONCLUSIONS
Development of IRD is possible in the presence of other chronic nephropathies. Diagnosis of IRD arising in patients suffering from other chronic renal diseases often requires radical change of therapeutic policy, but renal revascularization is not contraindicated.
