Advanced Chronic Kidney Disease

Chronic kidney disease (CKD) is a common disease in elderly dogs. The present study aims to evaluate the efficacy of a dietary supplement containing calcium carbonate, calcium-lactate gluconate, chitosan and sodium bicarbonate in dogs with IRIS stage 3 of CKD. Twenty dogs were enrolled in the study, ten were administered the new dietary supplementation for 180 days (T group) while the others were used as control group (C group). Haematologic, biochemical and urinalysis were performed every 30 days. A significant reduction in the T group compared to the C group in serum phosphorus level and increase in serum bicarbonate and ionized calcium values were recorded. The urine protein-to-creatinine ratio (UPC) was significantly lower in the T group at the end of the study compared to the C group. The tested supplement could be considered as a supportive treatment for dogs with advanced CKD.

Objective. To systematically evaluate the efficacy and safety of tanshinone for chronic kidney disease (CKD). Methods. Randomized controlled trials (RCTs) on the treatment of CKD using tanshinone were searched using 4 Chinese databases (China National Knowledge Infrastructure (CNKI), Value In Paper (VIP), Wanfang, and Chinese Biology Medicine (CBM)) and 3 English databases (PubMed, Cochrane Library, and Excerpta Medica Database (Embase)). The results included data on blood urine nitrogen (BUN), serum creatinine (Scr), glomerular filtration rate (GFR), 24 h urine protein, microalbuminuria (mALB), β2-macroglobulin (β2-MG), cystatin C (CysC), and safety events. The data were analyzed using Revman 5.3 and Stata 12.0 software. Results. Twenty-one studies were entered into this meta-analysis, which involved 1857 patients including 954 cases from the tanshinone treatment group and 903 cases from the control group. BUN levels in the tanshinone treatment group were significantly reduced compared with the control (standardized mean difference (SMD) = −0.65, 95% confidence interval (CI): −0.81 to −0.49, p<0.01). In addition, subgroup analysis indicated that tanshinone had a significant effect in reducing Scr levels at 14, 21, and 28 days. Scr levels in the tanshinone treatment group were significantly reduced compared with the control group (SMD = −1.40, 95% CI: −2.09 to −0.71, p<0.01); subgroup analysis based on treatment time also yielded the same results. GFR in the tanshinone treatment group was better than that in the control group (SMD = 0.83, 95% CI: 0.59 to 1.07, p<0.01). In terms of urine protein levels, 24 h urine protein level, mALB, and β2-MG of CKD patients were reduced to some degree compared with controls, and CysC levels in the tanshinone treatment group were also significantly reduced compared with the control group (SMD = −0.24, 95% CI: −0.44 to −0.03, p<0.05). Safety in the tanshinone treatment group did not differ significantly from that of the control group (risk ratio (RR) = 7.78, 95% CI: 0.99 to 61.05, p>0.05). Conclusion. This meta-analysis showed that tanshinone could control urine protein level in CKD patients, improve kidney function, and delay the evolution of CKD without significant side effects. However, the results were limited and should be interpreted with caution because of the low quality of the included studies. In the future, more rigorous clinical trials need to be conducted to provide sufficient and accurate evidence.

Abstract Background: As a co-receptor for fibroblast growth factor 23, klotho plays a pivotal role in phos-phate metabolism. The kidney is known to be not only the main source of soluble alpha-klotho but also functions as the principal regulator maintaining its concentration. Previous studies in human par-ticipants showed that the concentration of soluble alpha-klotho in serum and urine decreased in chronic kidney disease (CKD) patients. However, no previous study has assessed soluble alpha-klotho levels in dogs. This study aimed to measure serum and urinary alpha-klotho levels in CKD dogs and identify their associations with International Renal Interest Society (IRIS) CKD stages and other parameters known to be associated with CKD.Methods: Serum and urinary alpha klotho concentrations were measured by a commercially avail-able canine-specific sandwich enzyme-linked immunosorbent assay kit and compared between groups by a nonparametric Kruskal–Wallis test. Spearman’s correlation coefficient was used to eval-uate the relationships between variables. A stepwise multiple regression analysis was performed to estimate the effects of independent predictors on klotho concentrations.Results: The urine klotho-to-creatinine ratio (UrKl/Cr) was significantly lower in stage 3 dogs than the control group and was significantly lower in dogs with stage 3 and 4 CKD than in those with stage 1 and 2 disease. UrKl/Cr was negatively correlated with serum symmetric dimethylarginine (sSDMA), blood urea nitrogen (BUN), creatinine, and phosphorus concentration. Serum alpha-klotho concentration in dogs with stages 2 and 3 CKD were significantly lower than those in the control group. There was no significant correlation between serum alpha-klotho and BUN, creatinine, and phosphorus concentrations. No statistically significant differences were observed in UrKl/Cr and se-rum alpha-klotho concentration between groups based on sex, age, urine protein-to-creatinine ratio (UPC), or blood pressure.Conclusions: UrKl/Cr decreased in dogs with advanced CKD, and it was negatively correlated with sSDMA, BUN, creatinine, and phosphorus concentrations. Thus, klotho may play a role in the path-ogenesis of CKD and its clinical consequences, including CKD-mineral bone disorder, in dogs. Alt-hough serum klotho concentration was negatively correlated with sSDMA levels, it was not appar-ently related to IRIS CKD stage or other parameters known to be associated with CKD.

Abstract Introduction Current treatment for hypertension and volume overload in chronic kidney disease consists of loop diuretics, nevertheless, chronic use leads to adaptive changes at the distal nephron, which in turn decreases their efficacy. The use of thiazide diuretics could be another treatment option in these patients, notwithstanding, there's not enough evidence to justify their use in this population. Purpose To evaluate the efficacy and safety of treatment with bumetanide plus chlorthalidone in in patients with advanced chronic kidney disease. Methods A double-blind randomized controlled trial was conducted at our hospital. Thirty-two patients with hypertension, chronic kidney disease stage IV/V, and chronic loop diuretic use where divided in two groups. The dual treatment group received bumetanide (4 mg QD) plus chlorthalidone (100 mg QD), while the control group was given bumetanide (4 mg QD) plus placebo, both for twenty-eight days. Systemic blood pressure, bioimpedance, and urinary electrolytes were measured at seven and twenty-eight days of treatment. Results There was a significant decrease of systemic blood pressure in the dual treatment group when compared with the control group; systolic blood pressure −26.1±15.3 vs. −10±23.3 mmHg (p=0.028), diastolic blood pressure −13.5±10.7 vs. −3.4±11.9 mmHg (p=0.018), and mean arterial pressure −18.1±8.7 vs. −5.4±14.3 mmHg (p=0.006). There was also a significant decrease of volume overload in the dual treatment group when compared to the control group; total body water −4.36±3.29 vs. +0.075±1.78 litres (p&lt;0.001), extracellular water −2.55±1.1 vs. +0.150±1.2 litres (p&lt;0.001), and extracellular water to total body water ratio −2.92±4.76 vs. −0.24±1.42 (p=0.039). The treatment group increased its fractional excretion of sodium, while the control group demonstrated an increase, though differences were non-significant. As for adverse effects, there was a non-significant increase of urea and creatinine levels in the dual treatment group when compared with controls. Conclusions In advanced chronic kidney disease plus hypertension patients whose treatment with loop diuretics is insufficient, combined use of bumetanide plus chlorthalidone can be useful for systemic blood pressure and volume overload control.

Background Advanced chronic kidney disease is common in older people and is frequently accompanied by metabolic acidosis. Oral sodium bicarbonate is used to treat this acidosis, but evidence is lacking on whether or not this provides a net gain in health or quality of life for older people. Objectives The objectives were to determine whether or not oral bicarbonate therapy improves physical function, quality of life, markers of renal function, bone turnover and vascular health compared with placebo in older people with chronic kidney disease and mild acidosis; to assess the safety of oral bicarbonate; and to establish whether or not oral bicarbonate therapy is cost-effective in this setting. Design A parallel-group, double-blind, placebo-controlled randomised trial. Setting The setting was nephrology and geriatric medicine outpatient departments in 27 UK hospitals. Participants Participants were adults aged ≥ 60 years with advanced chronic kidney disease (glomerular filtration rate category 4 or 5, not on dialysis) with a serum bicarbonate concentration of < 22 mmol/l. Interventions Eligible participants were randomised 1 : 1 to oral sodium bicarbonate or matching placebo. Dosing started at 500 mg three times daily, increasing to 1 g three times daily if the serum bicarbonate concentration was < 22 mmol/l at 3 months. Main outcome measures The primary outcome was the between-group difference in the Short Physical Performance Battery score at 12 months, adjusted for baseline. Other outcome measures included generic and disease-specific health-related quality of life, anthropometry, 6-minute walk speed, grip strength, renal function, markers of bone turnover, blood pressure and brain natriuretic peptide. All adverse events were recorded, including commencement of renal replacement therapy. For the health economic analysis, the incremental cost per quality-adjusted life-year was the main outcome. Results In total, 300 participants were randomised, 152 to bicarbonate and 148 to placebo. The mean age of participants was 74 years and 86 (29%) were female. Adherence to study medication was 73% in both groups. A total of 220 (73%) participants were assessed at the 12-month visit. No significant treatment effect was evident for the primary outcome of the between-group difference in the Short Physical Performance Battery score at 12 months (–0.4 points, 95% confidence interval –0.9 to 0.1 points; p = 0.15). No significant treatment benefit was seen for any of the secondary outcomes. Adverse events were more frequent in the bicarbonate arm (457 vs. 400). Time to commencement of renal replacement therapy was similar in both groups (hazard ratio 1.22, 95% confidence interval 0.74 to 2.02; p = 0.43). Health economic analysis showed higher costs and lower quality of life in the bicarbonate arm at 1 year, with additional costs of £564 (95% confidence interval £88 to £1154) and a quality-adjusted life-year difference of –0.05 (95% confidence interval –0.08 to –0.01); placebo dominated bicarbonate under all sensitivity analyses for incremental cost-effectiveness. Limitations The trial population was predominantly white and male, limiting generalisability. The increment in serum bicarbonate concentrations achieved was small and a benefit from larger doses of bicarbonate cannot be excluded. Conclusions Oral sodium bicarbonate did not improve a range of health measures in people aged ≥ 60 years with chronic kidney disease category 4 or 5 and mild acidosis, and is unlikely to be cost-effective for use in the NHS in this patient group. Once other current trials of bicarbonate therapy in chronic kidney disease are complete, an individual participant meta-analysis would be helpful to determine which subgroups, if any, are more likely to benefit and which treatment regimens are more beneficial.
