Treatment With Gemfibrozil Prevents the Progression of Chronic Kidney Disease in Obese Dahl Salt-Sensitive Rats

Recently, we reported that Dahl salt-sensitive leptin receptor mutant (SSLepRmutant) rats exhibit dyslipidemia and renal lipid accumulation independent of hyperglycemia that progresses to chronic kidney disease (CKD). Therefore, in the current study, we examined the effects of gemfibrozil, a lipid-lowering drug (200 mg/kg/day, orally), on the progression of renal injury in SS and SSLepRmutant rats for 4 weeks starting at 12 weeks of age. Plasma triglyceride levels were markedly elevated in the SSLepRmutant strain compared to SS rats (1193 ± 243 and 98 ± 16 mg/day, respectively). Gemfibrozil treatment only reduced plasma triglycerides in the SSLepRmutant strain (410 ± 79 mg/dL). MAP was significantly higher in the SSLepRmutant strain vs. SS rats at the end of the study (198 ± 7 vs. 165 ± 7 mmHg, respectively). Administration of gemfibrozil only lowered MAP in SSLepRmutant rats (163 ± 8 mmHg). During the course of the study, proteinuria increased to 125 ± 22 mg/day in SS rats. However, proteinuria did not change in the SSLepRmutant strain and remained near baseline (693 ± 58 mg/day). Interestingly, treatment with gemfibrozil increased the progression of proteinuria by 77% in the SSLepRmutant strain without affecting proteinuria in SS rats. The renal injury in the SSLepRmutant strain progressed to CKD. Moreover, the kidneys from SSLepRmutant rats displayed significant glomerular injury with mesangial expansion and increased...

SummaryObesity is a treatable risk factor for chronic kidney disease progression. We audited the reporting of body ‐mass index in nephrology outpatient clinics to establish the characteristics of individuals with obesity in nephrology practice. Body‐mass index, clinical information and biochemical measures were recorded for patients attending clinics between 3rd August, 2018 and 18th January, 2019. Inferential statistics and Pearson correlations were used to investigate relationships between body ‐mass index, type 2 diabetes, hypertension and proteinuria. Mean ± SD BMI was 28.6 ±&th...

Introduction: Hypertension is a cause and consequence of chronic kidney disease globally. The other factors that work in concert with hypertension to cause CKD are yet to be clearly elucidated. Studies have identified proteinuria, dyslipidemia, obesity, smoking and family history of CKD as renal risk factors. Due to the high morbidity and mortality associated with occurrence of CKD including the enormous financial burden involved in its management, the knowledge of prevention and understanding of the risk factors for development of CKD is highly essential. Therefore, Identifying well defined risk factors that display stron...

This study enrolled 14983 eligible subjects stratified into metabolically healthy normal weight (MHNW), metabolically healthy overweight (MHOW), metabolically healthy obesity (MHO), metabolically unhealthy normal weight (MUNW), metabolically unhealthy overweight (MUOW), and metabolically unhealthy obesity (MUO) according to body mass index and metabolic syndrome status (ATP-III criteria). The metabolic healthy phenotype was defined as the absence of both metabolic syndrome and any known diabetes, coronary artery disease, stroke, hypertension or dyslipidemia. Early and advanced CKD were defined as eGFR

Abstract Among patients with chronic kidney disease (CKD), hypertension (HTN) is very common and widely recognized to accelerate the progression of CKD and increase the risk for cardiovascular events. Accumulated data indicate that ambulatory blood pressure monitoring (ABPM) is better in detecting HTN than office blood pressure (BP) measurement. The goal of this study is to describe the ABPM characteristics in a group of CKD and hypertensive patients. A transversal study was conducted over a period of six months, to evaluate the ABPM patterns among a group of hypertensive patients with CKD (Group 1) and compared t...

In this study, we investigated the antihypertensive effect and underlying mechanisms of P. asiatica L. seeds extract (PASE) in spontaneously hypertensive rat (SHR). Male SHRs were treated with 2.5 mg/kg of fosinopril (FOS) and 400 mg/kg of PASE orally per day for once or 12 weeks. SHR or Wistar-Kyoto rats (WKY) receiving vehicle (distilled water) was used as control. The results demonstrated systolic, diastolic, and mean blood pressures (SBP, DBP, and MBP) were significantly lowered after single and long-term intragastric administration of PASE. The cardiac and aortic index and collagen accumulation were improved in the PA...

Conclusion: Periodontal disease is significantly and positively correlated with increased risk of hypertension in Chinese population, and exact mechanisms of this association should be explored in future. Introduction Periodontal disease is a complex polymicrobial inflammation, including gingivitis and periodontitis. According to the 2015 Global Burden of Disease (GBD) study, the prevalence of severe chronic periodontitis in 2015 has reached 616 million (Kassebaum et al., 2017). In China, the periodontal disease standardized DALYs rate has risen from 24.7 in 1990 to 25.7 in 2013 according to the data from 2013 GBD ...

In this study, we investigated the genetic contribution to renal disease in Tiwi Islanders by conducting a GWAS, in which associations were tested between SNP genetic variants and single measure ACR levels. A number of nominally significantly associated SNPs were identified. These SNPs did not reach genome wide significance, probably due to the small sample size. The top eight SNPs were re-tested for association in a separately collected cohort from the same population. Four of these SNPs were significantly associated with ACR in the replication sample (p

Conclusion: Diabetes was found to be a bigger cause (62.3%) of CKD than what has been reported thus far in India. At presentation association of diabetic-CKD with HT was recorded higher (78.7%) in India. Hence use of the syndrome "DHKD", (complex of diabetes, hypertension and kidney disease) is justifiable. Our study shows 54.4% of diabetic patients attending medicine OPD were uninvestigated by either physician or GP for CKD because urine albumin and serum creatinine tests were lacking. Thus, progression to CKD in many patients went unnoticed. Syndromic diagnosis of "DHKD" therefore in our view is impor...
