Introduction. Hypertension, particularly pulse pressure [PP] is a major risk factor for end-stage renal disease. However, the effect of individual components of hypertension namely PP, systolic [SBP] and diastolic blood pressure [DBP] on kidney function, in the general African population is unknown. Methods. Data were collected on 944 participants [aged 40-75 y], living in villages in the area around the city of Kumasi, Ghana, on demographics, medications, height, weight, BP and 24-hour creatinine clearance (CrCl). Results. The demographic and clinical characteristics were: age 55(11) [mean (SD)] years, females 62%, rural village-dwellers 52%, diabetes 1·5%, BMI 21(4) kg/m2, 24-hourCrCl as a measure of glomerular filtration rate (GFR) 84(23) ml/min/1.73 m2. 29% had BP >140/90 mmHg; SBP and DBP were 125/74(26/14) mmHg, PP was 51(17) mmHg. PP increased with age by 0.55(95% CI: 0.46,0.64) mmHg/year. PP was higher (53(17) v 49(15) mmHg; p < 0.001) in the semiurban participants. GFR decreased both with increasing PP [-0.19 (-0.27,-0.10 ml/min/1.73 m2/mmHg; p < 0.001] and SBP [-0.09 (-0.14,-0.03) ml/min/1.73 m2/mmHg; p < 0.001] but there was no significant relationship with DBP [-0.04 (-0.15,0.06)]. After adjusting for SBP, the relationship between GFR and PP became steeper [-0.31 (-0.50,-0.12) ml/min/1.73 m2/mmHg; p < 0.001]. Using multivariate regression analysis that included PP, age, gender, BMI, only increasing age [-0.75 (-0.88,-0.62)] and decreasing BMI [0.49 (0.16,0.81)] were associated with decreased kidney function. Conclusions. In this homogeneous West-African population, PP increased with age and had a steeper relationship with declining kidney function than SBP or DBP.

Background: The timely identification of traditional and non-traditional precursors and risk factors for chronic kidney disease (CKD) (a common systemic disease defined as a decreased kidney function documented by reduced glomerular filtration rate, or markers of kidney damage, or both) is relevant in clinical practice, as CKD increases the risk of end-stage renal disease and other serious comorbidities. A possible relationship between non-alcoholic fatty liver disease (NAFLD) (which is to date the most common chronic disease worldwide) and CKD has recently gained significant attention of researchers. Methods : A systematic literature search using appropriate keywords was made in order to identify relevant articles that have investigated the association between NAFLD and CKD. Results: Several observational studies and meta-analyses have reported the existence of an independent association between NAFLD and risk of CKD in patients with and without diabetes. However, whilst the association between NAFLD and risk of prevalent CKD is strong across various patient populations, whether NAFLD is independently associated with the development and progression of CKD is still debatable. Moreover, emerging evidence now suggests a potential association between patatin-like phospholipase domain-containing protein-3 (PNPLA3) rs738409 genotype (the most important genetic variant associated to NAFLD) and decreasing kidney function, independent of NAFLD. Conclusions : Convincing evidence now indicates that CKD is increased among patients with NAFLD. For this reason, patients with NAFLD should be regularly monitored for renal function and, on the other hand , NAFLD should be considered in all patients with CKD, especially if they are obese or have type 2 diabetes.

Background: Hemodialysis is the main approach for renal replacement therapy in patients with end-stage renal disease (ESRD) in China. The timing of dialysis initiation is one of the key factors influencing patient survival and prognosis. Over the past decade, the relationship between the timing of dialysis initiation and mortality has remained unclear in patients with ESRD in China. Methods: Patients who commenced maintenance hemodialysis from 2009 to 2014 from 24 hemodialysis centers in Mainland China were enrolled in the study (n = 1,674). Patients were divided into 2 groups based on the year they started hemodialysis (patients who started hemodialysis from 2009 to 2011, and patients who started hemodialysis from 2012 to 2014). Analysis of the yearly change in the estimated glomerular filtration rate (eGFR) at the initiation of dialysis was performed for the 2 groups. Meanwhile, the patients were divided into 3 groups based on their eGFR at the initiation of dialysis (<4, 4–8, and >8 mL/min/1.73 m2). For these 3 groups, the relationship between the eGFR at the start of dialysis and mortality were analyzed. Results: The average eGFRs were 5.68 and 5.94 mL/min/1.73 m2 for 2009–2011 and 2012–2014, respectively. Compared with the 2009–2011 group, the proportion of patients with diabetes in 2012–2014 increased from 26.7 to 37.7%. The prognosis of patients with different eGFRs at the start of dialysis was analyzed using Kaplan-Meier survival curves. After adjusting for confounding factors through a Cox regression model, no significant difference was demonstrated among the 3 groups (<4 mL/min/1.73 m2 was used as the reference, in comparison with 4–8 mL/min/1.73 m2 [p = 0.681] and >8 mL/min/1.73 m2 [p = 0.403]). Conclusion: In Mainland China, the eGFR at the start of dialysis did not change significantly over time from 2008 to 2014 and had no association with the mortality of patients with ESRD.

Interdialytic weight gain in patients with hemodialysis depends on fluid, salt intake in interdialytic period and compliance of dialysis patients. In end stage renal disease(ESRD) patients due to decreased and absent residual urine output there is salt and water retention in body which leads to interdialytic weight gain. Overhydration and IDWG is assumed to be the main cause of pre hemodialysis raised blood pressure(BP) in ESRD patients. Here the relationship between IDWG and pre HD blood pressure is studied in 40 hemodialysis patients. We recorded pre HD BP and IDWG in four subsequent hemodialysis sessions for each patient during the period of 2 weeks in patients who are on twice weekly hemodialysis. so, in total we studied 160 hemodialysis sessions. Mean of four pre HD BP is compared with mean of four IDWG for each patient. Then correlation between 40 mean IDWG and 40 mean pre HD BP is studied and also correlation between IDWG and pre HD blood pressure during 160 hemodidlysis sessions studied individually.

Staphylococcus aureus is a troublesome pathogen, responsible for a broad range of clinical manifestations, ranging from benign skin infections to life-threatening conditions such as endocarditis and osteomyelitis. The kidney can be affected through a rapidly progressive glomerulonephritis mediated by an inflammatory reaction against a superantigen deposited in the glomerulus during the infection’s course. This glomerulopathy has a poor prognosis, often leading to chronically impaired kidney function, eventually progressing to end-stage renal disease. Treatment rests on antibiotherapy. Despite the inflammatory role in this disease’s pathophysiology, most authors discourage a simultaneous immunosuppressive approach given the concomitant infection. However, there are some reports of success after administration of systemic corticosteroids in these patients. We present a 66-year-old man with a staphylococcus-induced glomerulonephritis brought on by a vascular graft infection, with rapidly deteriorating kidney function despite extraction of the infected graft and 3 weeks of antibiotherapy with achievement of infection control. Kidney function improved after the introduction of corticosteroids. This case highlights the potential role of corticosteroids in selected cases of staphylococcus-induced glomerulonephritis, particularly those in which the infection is under control.

Introduction: Carotid intima-media thickness (IMT) has been reported to predict kidney function decline. However, whether carotid IMT is associated with a hard kidney endpoint, end-stage renal disease (ESRD), has not been investigated. Hypothesis: We assessed the hypothesis that increased carotid IMT is associated with ESRD risk. Methods: We studied 13,197 ARIC participants at visit 1 (1987-1989) without history of cardiovascular disease including coronary heart disease, stroke and heart failure and assessed whether carotid IMT measured by B-mode ultrasound is associated with ESRD risk using Cox proportional-hazards models. Regarding carotid IMT parameters, we investigated the mean and maximum values of overall and segment-specific (common, bifurcation and internal carotid arteries) measurements. Results: Mean age was 54.0 (SD 5.7) years, and there were 3,373 (25.6%) blacks and 7,370 (55.8%) women. During a median follow-up of 22.7 years, 433 participants developed ESRD (1.4/1,000 person-years). After adjusting for shared risk factors for atherosclerosis and kidney disease, including baseline kidney function, carotid IMT was significantly associated with ESRD risk (hazard ratios between quartiles 4 and 1, 1.43 [95%CI: 1.01-2.04] for overall mean IMT and 1.73 [95%CI: 1.22-2.44] for overall maximum IMT). The associations were largely consistent in demographic and clinical subgroups. When we explored segment-specific IMTs, the associations with ESRD were most robust for bifurcation carotid. The adjusted hazard ratios between quartiles 4 and 1 were 1.48 (95%CI: 1.04-2.11) for mean bifurcation IMT and 1.42 (95%CI: 0.99-2.03) for maximum bifurcation IMT. Conclusions: Carotid IMT was independently associated with incident ESRD in the general population. Our findings suggest the shared etiology between atherosclerosis and ESRD and highlight the importance of monitoring kidney function over time in individuals with subclinical atherosclerosis.
