The Relationship

Background Peritoneovenous shunts (PVS) are widely used for palliation of intractable ascites caused by peritoneal carcinomatosis (PC) or liver cirrhosis (LC). Some patients who need PVS have renal dysfunction. However, renal dysfunction is considered a relative contraindication. Therefore, it is important to assess renal function before PVS placement. Purpose To evaluate the relationship between PVS and renal function. Material and Methods Between October 2007 and July 2015, 60 patients (PC = 47; LC = 10; others = 3) underwent PVS placement for intractable ascites. Changes in estimated glomerular filtration rate (eGFR) and other adverse events (AEs) were retrospectively analyzed. Results Changes in eGFR before, one day after, and one week after PVS placement could be evaluated in 46 patients. The median eGFR before, one day after, and one week after was 56.5, 59.1, and 64.7 mL/min/1.73 m2, respectively ( P < 0.05). These values were 61.6, 72, and 67.1 mL/min/1.73 m2, respectively, in PC patients (n = 34; P < 0.05) and 28.5, 27, and 37.2 mL/min/1.73 m2, respectively, in LC patients (n = 10; P < 0.05). In 17 patients with moderate to severe renal dysfunction (eGFR < 45), these values were 23.4, 23.7, and 30.5 mL/min/1.73 m2, respectively. The most frequent AE was PVS catheter obstruction, which occurred in 12 patients (20.7%). Clinical disseminated intravascular coagulation occurred in six patients (10.3%) and caused death in three patients (5.2%). Conclusion PVS placement for intractable ascites is associated with various AEs. However, PVS appeared to promote renal function, especially in patients with renal impairment.

We previously demonstrated a dose-dependent improvement in renal function and reduction in cardiovascular risk in TNT with intensive lipid lowering with atorvastatin (ATV) 80 mg vs 10 mg. This post hoc analysis examines the relationship between the observed improvement in estimated glomerular filtration rate (eGFR) and reduction of major cardiovascular events (MCVE). After 8 weeks open-label therapy with ATV 10 mg, 10,001 patients with CHD were randomized to double-blind therapy with either ATV 10 or 80 mg. Patients were followed for a median of 4.9 years for the occurrence of MCVEs (CHD death, nonfatal MI, and stroke). The relationship between change from baseline eGFR (using the MDRD equation) at the final visit prior to a MCVE and the risk of MCVE was assessed using a Cox proportional hazards model adjusting for baseline eGFR and other baseline characteristics. Of 9656 patients with complete renal data, 156 had a MCVE before follow-up eGFR assessment and were excluded. In the remaining 9500 patients, mean baseline eGFR was 65.3 mL/min/1.73 m 2 and mean change from baseline was 4.3 mL/min/1.73 m 2 . This represented a reduction in the risk of MCVE of 2.7% per mL increase in eGFR (HR 0.973, 95% CI 0.967– 0.980, P <0.0001). This association remained significant in patients with eGFR <60 and those with eGFR ≥60 mL/min/1.73 m 2 at baseline, with no significant interaction between eGFR change and baseline renal status ( P =0.98). A 5 mL/min on-treatment improvement in eGFR was associated with a 12.6% reduction in MCVE, while a 5 mL/min reduction was associated with a 14.4% increase in MCVE. Mean change from baseline eGFR was 3.5 mL/min/1.73 m 2 with ATV 10 mg and 5.2 mL/min/1.73 m 2 with ATV 80 mg, representing significant 9.3% and 12.4% reductions in risk, respectively. Analysis of interaction between treatment and eGFR change for prediction of MCVE demonstrated a stronger association between eGFR change and MCVE in the ATV 80 mg treatment group ( P =0.011). Improvement in eGFR was highly associated with a reduction in MCVE, irrespective of baseline renal function. This relationship was dose dependent. Improvement in eGFR may be a biomarker for the response to atorvastatin, and for the stabilization of atherosclerotic cardiovascular disease.

The Relationship

Regarding the diet treatment of diabetic nephropathy, protein restriction has been recommended. American Diabetes Association (ADA) proposed protein restriction guidelines in the 2008 edition. However, this comment was deleted in the 2013/2019 edition, because of insufficient evidence. A recent report showed that the intake of plant protein has a protective effect on the decrease of estimated glomerular filtration rate (eGFR), and the intake of animal protein has neither protection nor deterioration. There are controversies about the relationship between protein intake and the reduction of renal function. Further research will be expected for diabetic nephropathy, diabetic kidney disease (DKD), and chronic kidney disease (CKD).

INTRODUCTION: The increasing prevalence of chronic kidney disease (CKD) is a major health problem. The prevalence of obesity has also been rapidly increasing worldwide. Few studies have examined the relationship between excess body weight and CKD risk. Aim: To evaluate the possible contribution of increased body mass index (BMI) to impaired renal function in the general population sample. METHODS: The study involved 500 participants older than 30 years (228 men, 272 women, age 57.58±13.68) who visited their general practitioner in Health Center "Dr Simo Milošević". Blood samples, blood pressure anthropometric measures were performed on each participant. Estimated glomerular filtration rate was calculated using the abbreviated equation from MDRD study ("the Modification of Diet in Renal Disease Study") and CKD was defined as eGFR less than 60 ml/min/1.73m². Statistical analysis was performed using SPSS 19.0 software (IBM, Somers, New York, USA). RESULTS: The mean BMI was 25.09±3.54 kg/m² with 0.6% in underweight (BMI<18.5 kg/m²), 17.6% in lower normal (BMI 18.5 to 21.9 kg/m²), 33.2% in upper normal (BMI 22.0 to 24.9 kg/m²) and 48.6% in overweight or obese (BMI>25.0 kg/m²) body mass category. The mean eGFR was 100.33±30.78 ml/min/1.73m² with 112±8.62 in underweight, 116.94±3.8 in lower normal, 102.37±2.39 in upper normal and 92.78±1.72 in overweight or obese category. Estimated GFR values decreased significantly with increasing BMI specially in those in upper normal compared to lower normal (p<0.001) and overweight and obese compared to lower normal body mass category (p<0.001). Compared with participants with lower normal body mass, the non-adjusted odds ratio (OR) for mildly or moderately reduced renal function (eGFR<90 ml/min/1.73m²) was 2.54 (95% CI 1.41-4.56) for upper normal and 3.26 (95% CI 1.88-5.70) for overweight and obese participants. After adjusting for potential confounding variables (age, sex, diabetes mellitus, hypertension, hypercholesterolemia, hypertriglyceridemia and smoking status) or for mildly or moderately reduced renal function was 2.23 (95% CI 1.21-4.10) for upper normal 2.65 (95% CI 1.44-4.87) for overweight or obese participants compared to those in lower normal body mass category. CONCLUSION: Estimated GFR values decreased significantly with increasing BMI specially in those in upper normal compared to lower normal (p<0.001) and overweight and obese compared to lower normal body mass category (p<0.001). This study showed that increasing BMI is strongly associated with decreasing eGFR in the general population. The underlying mechanism behind this association remains to be investigated through prospective population-based studies.

Introduction: Simple renal cysts (SRCs) are the most common acquired cystic kidney disease, but the relationship between SRCs and renal function has not been clarified in patients with type 2 diabetes mellitus (T2DM).Methods: A retrospective study was conducted to analyze the clinical features of renal cysts and ultrasound data of the kidney in 4,304 patients with T2DM.Results: The prevalence of SRCs in patients with T2DM was 21.1%. Compared to patients with no SRCs, patients with SRCs had worse renal function (estimated glomerular filtration rate: 108.65 ± 40.93 vs. 92.38 ± 42.1 ml/min/1.73 m2, p &lt; 0.05). After adjusting the confounders, SRC was related to estimated glomerular filtration rate in patients with T2DM [odds ratio = 1.49, 95% confidence interval (1.24, 1.79), p &lt; 0.01]. Age, gout, proteinuria, cerebrovascular disease (CVD), and increased serum phosphorus levels were associated with SRCs in patients with T2DM.Conclusion: SRCs are associated with worse renal function in patients with T2DM. More attention should be paid to gout, proteinuria, CVD, serum phosphorus levels, and renal function in T2DM patients with SRCs.

Abstract Background and aims. Obese individuals have insulin resistance status assessed in the present study by the HOMA index (“Homeostasis model assessment”). This prospective study assessed renal disorders in the insulin resistance in obese patients. Material and Methods. The study included 73 young obese patients. The assessment included the HOMA index before meal and parameters of renal function (glomerular filtration rate, albuminuria, β2-microglobulinuria). Results. In young obese, insulin-resistance patients, glomerular hyperfiltration and β2-microglobulinuria are found in 77.0 and 93.4% of cases respectively. The albuminuria is noted in some cases, which reduces diagnostic value. Conclusions. In young obese patients with insulin resistance, glomerular hyperfiltration and β2-microglobulinuria are main diagnostic markers of renal dysfunction.

Abstract In liver cirrhosis patients awaiting liver transplantation, it is prognostically equally important to assess the renal function before and after transplantation. This is evidenced by the inclusion of serum creatinine in the Model for End-Stage Liver Disease (MELD) score. Most of the causes of renal failure in liver cirrhosis are functional, the acute kidney damage including prerenal azotemia, acute tubular necrosis and hepatorenal syndrome. A major index of the renal function, the glomerular filtration rate (GFR) is determined in a specific way in patients with liver cirrhosis. Clinically, serum creatinine is considered the best indicator of kidney function, although it is rather unreliable when it comes to early assessment of renal dysfunction. Most of the patients with liver cirrhosis have several concomitant conditions, which are the reason for the false low creatinine levels, even in the presence of moderate to severe kidney damage. This also holds for the creatinine clearance and creatinine-based estimation equations for assessment of the glomerular filtration rate (the Cockroft-Gault and MDRD formulas), which overestimate the real glomerular filtration. Clearance of exogenous markers is considered a gold standard, but the methods for their determination are rather costly and hard to apply. Alternative serum markers (e.g., cystatin C) have been used, but they should be better studied in cases of liver cirrhosis assessment.
