Atorvastatin
Opis:
Background. There is evidence that dyslipidemia is associated with chronic kidney disease (CKD) and it has been implicated in the progression of renal damage. Optimal management of dyslipidemia should therefore lead to renal benefits. A number of experimental models demonstrate a beneficial effect of statins in ameliorating renal damage. However, the exact mechanism by which statins protect against renal damage remains unclear. Methods. In a placebo-controlled, randomized, cross-over study we evaluated the influence of atorvastatin (ATO) 40 mg/day added to the renin-angiotensin-aldosterone systeme (RAAS) blockade on proteinuria and surrogate biomarkers of tubular damage or injury in 14 non-diabetic patients with proteinuria (0.4-1.8 g per 24 h) with normal or declined kidney function (eGFR 55-153 ml/min). In the eight-week run-in period, therapy using angiotensin converting enzyme inhibitors (ACEI) and/or angiotensin II subtype 1 receptor antagonists (ARB) was adjusted to achieve a blood pressure below 130/80 mm Hg. Next, patients were randomly assigned to one of two treatment sequences: ATO/washout/placebo or placebo/washout/ATO. Clinical evaluation and laboratory tests were performed at the randomization point and after each period of the study. The primary end point of this study was a change in proteinuria measured as 24-h urine protein excretion (DPE). Secondary end points included urine N-acetyl-β-d-glucosaminidase (NAG) and α1-microglobulin (α1m) excretion. Results. The ATO therapy significantly reduced urine excretion of α1m (p=0.033) and NAG (p=0.038) as compared to placebo. There were no differences in proteinuria, blood pressure, eGFR and serum creatinine between the ATO and placebo groups. Conclusion. Atorvastatin treatment is safe and improves biomarkers of tubular damage or injury in non-diabetic patients with CKD.

Opis:
Background: Inhibition of the renin-angiotensin-aldosterone system (RAAS) with angiotensin converting enzyme inhibitors (ACEI) and/or angiotensin II subtype 1 receptor antagonists (ARB) is a common strategy used in the management of patients with chronic kidney disease (CKD). However, there is no universal therapy that can stop progression of CKD. Pentoxifylline (PTE) is a non-specific phosphodiesterase inhibitor with anti-inflammatory properties. It has been reported to have promising effects in CKD treatment. Methods: In a placebo-controlled, randomized, cross-over study we evaluated the influence of PTE (1200 mg/day) added to RAAS blockade on proteinuria, surrogate markers of tubular injury and oxidative stress-dependent products in 22 non-diabetic patients with proteinuria (0.4-4.3 g per 24h) with normal or declined kidney function [eGFR 37-178 mL/min]. In an eight-week run-in period, therapy using ACEI and/or ARB was adjusted to achieve a blood pressure below 130/80 mm Hg. Next, patients were randomly assigned to one of two treatment sequences: PTE/washout/placebo or placebo/washout/PTE. Clinical evaluation and laboratory tests were performed at the randomization point and after each period of the study. Results: The PTE therapy reduced proteinuria (by 26%) as compared to placebo. There were no differences in α1-microglobulin, urine excretion of N-acetyl-β-d-glucosaminidase (NAG), hsCRP, the urinary excretion of 15-F2t-isoprostane, blood pressure (BP), eGFR and serum creatinine between the PTE and placebo groups. Conclusion: Pentoxifylline may decrease proteinuria in non-diabetic patients with CKD.
