Renal Artery Occlusion

Acute renal failure (ARF) is a serious medical complication characterized by an abrupt and sustained decline in renal function. Despite significant advances in supportive care, there is currently no effective treatment to restore renal function. PGE2 is a lipid hormone mediator abundantly produced in the kidney, where it acts locally to regulate renal function; several studies suggest that modulating EP4 receptor activity could improve renal function following kidney injury. An optimized peptidomimetic ligand of EP4 receptor, THG213.29, was tested for its efficacy to improve renal function (glomerular filtration rate, renal plasma flow, and urine output) and histological changes in a model of ARF induced by either cisplatin or renal artery occlusion in Sprague-Dawley rats. THG213.29 modulated PGE2-binding dissociation kinetics, indicative of an allosteric binding mode. Consistently, THG213.29 antagonized EP4-mediated relaxation of piglet saphenous vein rings, partially inhibited EP4-mediated cAMP production, but did not affect Gαi activation or β-arrestin recruitment. In vivo, THG213.29 significantly improved renal function and histological changes in cisplatin- and renal artery occlusion-induced ARF models. THG213.29 increased mRNA expression of heme-oxygenase 1, Bcl2, and FGF-2 in renal cortex; correspondingly, in EP4-transfected HEK293 cells, THG213.29 augmented FGF-2 and abrogated EP4-dependent overexpression of inflammatory IL-6 and of apoptotic death domain-associated protein and BCL2-associated agonist of cell death. Our results demonstrate that THG213.29 represents a novel class of diuretic agent with noncompetitive allosteric modulator effects on EP4 receptor, resulting in improved renal function and integrity following acute renal failure.

Renal Artery Occlusion

Three cases of successful kidney revascularization and recovery of renal function are presented in this study. In all three cases, renal failure and renovascular hypertension were caused by renal artery occlusion associated with aortic aneurysm (two abdominal and one thoracoabdominal). Prior to operation, one patient required dialysis 4 months, one 25 days and one 2 days. After kidney revascularization, renal function recovered immediately in the first case, in the second case after three months, and in the third case after 10 days. In one case, blood pressure restored to normal without medical therapy, while in two other cases blood pressure decreased nearly to normal with minimal medical therapy. In appropriately selected cases, revascularization of the occluded renal artery is recommended for treatment of both renal failure and renovascular hypertension. In such cases, collateral circulation is crucial to enable the preservation of dysfunctional kidney.

Ischemic Acute Renal Failure

To investigate the potential pathogenetic and therapeutic roles of thromboxane A2 (TXA2) and its receptor blockade, respectively, in the early phase of ischemic acute renal failure (ARF), renal function, TXB2 excretion, and the effects of the specific TXA2 receptor antagonist sulotroban (SU) in a model of unilateral renal artery occlusion in conscious female Sprague-Dawley rats were studied. Occlusion of the left renal artery for 1 h in untreated (i.e., vehicle-treated) rats (N = 8) resulted in oliguric ARF. In SU-treated rats (N = 8), the drug was given as an i.v. bolus of 5 mg/kg body wt, followed by a continuous infusion of 0.5 mg/min.kg body wt from 1 h before and during ischemia and for 6 h after reflow. After 1 h of ischemia, urine volume of left ischemic kidneys from untreated rats had decreased from 13.2 +/- 2.8 to 1.0 +/- 0.3 and 0.5 +/- 0.2 microL/min.100 g at 2 and 6 h of reflow, respectively, and GFR had decreased from 0.32 +/- 0.04 mL/min.100 g body wt to undetectable values. At 6 h of reflow, medullary Na-K-ATPase was slightly (P < 0.05) reduced in left ischemic kidneys, whereas medullary and papillary enzyme activities were compensatorily increased (P < 0.01) in right intact kidneys. The ADP/O ratio of cortical mitochondria was 41% (P < 0.05) and ATP synthesis was 77% (P < 0.01) lower than in right intact kidneys.(ABSTRACT TRUNCATED AT 250 WORDS)

Occlusive Cuff

Transient postocclusive renal vasospasm occurred in nine conscious postoperative monkeys with electromagnetic flowmeters implanted on the left renal artery. During an interval of 5–7 days, beginning approximately 1 wk after the implantation of an electromagnetic flowmeter and pneumatic occlusive cuff on the renal artery, occlusions produced by 2- to 15-s inflations of the cuff were invariably followed by flow reduction of 40%–90%, which began 30–60 s after occlusion and lasted from 3 to 60 min. These flow reductions were not related to changes in heart rate, cardiac output, blood pressure, nor to flow in other branches of the aorta; nor were they affected by papaverine (5 mg/kg), propranolol (1 mg/kg), phentolamine (3–5 mg/kg per min), or dipyridamole (1 mg/kg). This response to renal artery occlusion disappeared after 5-7 days and did not recur. This phenomenon should be kept in mind when planning experiments involving long-term implantation of flowmeters on the renal arteries of monkeys.
