Ischaemic nephron injury, caused by afferent arteriole constriction, develops in early stages of cyclosporine-induced nephropathy [6].
Activation of the renin-angiotensin system with reductions in nitric oxide, prostaglandin E2, and prostacyclin leads to vasoconstriction of the afferent arteriole. The effect is a dose dependent and reversible elevation in blood pressure and reduction in glomerular filtration rate [3].
(c and d) Correlation between urinary 8OHdG levels and the degree of podocytopathy, as determined by desmin-positive area (c), or the degree of arteriolopathy, as determined by the afferent arteriole thickness (d).
This is secondary to renal vasoconstriction of the afferent arteriole. The deoxycholate moiety is nephrotoxic and accounts for the differential renal toxicity of Amphotericin B deoxycholate as compared with lipid compounds.
In the kidney, it causes strong vasoconstriction of the efferent arteriole and moderate vasoconstriction of the afferent arteriole, directly stimulates the reabsorption of sodium ions in the proximal tubule, thereby contributing to an increased volume of extracellular fluid and the development of hypertension [1,2].

The mechanism for this change in renal blood flow may in part relate to chelator-induced iron depletion, affecting the afferent arteriole via an up-regulation of prostaglandin production and arteriole vasoconstriction.
Amphotericin B may cause renal impairment by two mechanisms: binding to tubular epithelial cells causing cell swelling and lysis, ultimately resulting in tubular dysfunction, and activating vasoconstrictive prostaglandins in the afferent arteriole. Risk factors for amphotericin B-induced renal toxicity include volume depletion, pre-existing renal impairment, use of concomitant nephrotoxins, and high single and cumulative doses.
