Acid retention in chronic kidney disease is inversely related to GFR

Greater H+ retention in animal models of chronic kidney disease (CKD) mediates faster glomerular filtration rate (GFR) decline and dietary H+ reduction slows eGFR decline in CKD patients with reduced eGFR and H+ retention due to the high acid (H+) diets of developed societies. We examined if H+ retention in CKD is inversely associated with estimated GFR (eGFR) using cross-sectional and longitudinal analysis of individuals with CKD stage 1 (>90 ml·min− 1·1.73 m−2), CKD stage 2 (60–89 ml/min per 1.73 m2), and CKD stage 3 (30–59 ml·min− 1·1.73 m−2) eGFR. H+ retention was assessed using the difference between observed and expected plasma total CO2 2 h after 0.5 meq/kg body wt oral NaHCO3. H+ retention was higher in CKD 2 vs. CKD 1 ( P < 0.01) and in CKD 3 vs. CKD 2 ( P < 0.02) at baseline and 5 yr, and was higher in CKD 2 vs. CKD 1 ( P < 0.01) at 10 yr. All groups had lower eGFR at subsequent time points ( P < 0.01) but H+ retention was not different among the three time points for CKD 1. By contrast, eGFR decrease was associated with higher H+ retention in CKD 2 at 5 yr ( P = 0.04) and 10 yr ( P < 0.01) and with higher H+ retention in CKD 3 at 5 yr ( P < 0.01). Yearly eGFR decline rate was faster in CKD 2 vs. CKD 1 ( P < 0.01) and in CKD 3 vs. CKD 2 ( P < 0.01). The data show that H+ retention is inversely associated with eGFR, with faster eGFR decline, and support the need for greater dietary H+ reduction therapy for CKD individuals with lower eGFR.

Background and objectives: Chronic kidney disease (CKD) in children is a complex medical and social issue around the world. One of the serious complications is mineral-bone disorder (CKD-MBD) which might determine the prognosis of patients and their quality of life. Fibroblast growth factor 23 (FGF-23) is a phosphaturic hormone which is involved in the pathogenesis of CKD-MBD. The purpose of the study was to determine what comes first in children with CKD: FGF-23 or phosphate. Materials and Methods: This cross-sectional study included 73 children aged 2–18 years with CKD stages 1–5. We measured FGF-23 and other bone markers in blood samples and studied their associations. Results: Early elevations of FGF-23 were identified in children with CKD stage 2 compared with stage 1 (1.6 (1.5–1.8) pmol/L versus 0.65 (0.22–1.08), p = 0.029). There were significant differences between the advanced stages of the disease. FGF-23 correlated with PTH (r = 0.807, p = 0.000) and phosphate (r = 0.473, p = 0.000). Our study revealed that the elevated level of FGF-23 went ahead hyperphosphatemia and elevated PTH. Thus, more than 50% of children with CKD stage 2 had the elevating level of serum FGF-23, and that index became increasing with the disease progression and it achieved 100% at the dialysis stage. The serum phosphate increased more slowly and only 70.6% of children with CKD stage 5 had the increased values. The PTH increase was more dynamic. Conclusions: FGF-23 is an essential biomarker, elevates long before other markers of bone metabolism (phosphate), and might represent a clinical course of disease.

INTRODUCTION: Chronic Kidney Disease (CKD) is dened as a disease characterized by alterations in either kidney structure or function or both for a minimum of 3 months duration. According to the National Kidney Foundation criteria, 1 CKD has been classied into ve stages with stage 1 being the earliest or mildest CKD state and stage 5 being the most severe CKD stage. To stage CKD, it is necessary to estimate the GFR rather than relying on serum creatinine concentration. Glomerular ltration rate (GFR), either directly measured by computing urinary clearance of ltration marker such as inulin or estimated by calculating from different equations using serum creatinine. is the most commonly used parameter to assess kidney function. AIM AND OBJECTIVES: a) Establish relationship between serum CKD and eGFR MATERIAL AND METHOD: A Cross-sectional study on 100 cases of newly diagnosed Chronic Kidney Disease patients and matched control subjects is undertaken to study.100 Patients who are newly diagnosed as CKD are selected after proper initial screening. RESULT AND ANALYSIS: In case, the mean eGFR (mean± s.d.) of patients was 25.1500 ± 11.8929. In control, the mean eGFR (mean± s.d.) of patients was 87.2200 ± 17.8295. Difference of mean eGFR in two groups was statistically signicant (p<0.0001). In case, the mean creatinine (mean± s.d.) of patients was 3.6350 ± 2.4419 mg/dl. In control, the mean creatinine (mean± s.d.) of patients was .9435 ± .1317 mg/dl. Difference of mean creatinine in two groups was statistically signicant (p<0.0001). CONCLUSION: eGFR was strongly associated with CKD that also statistically signicant. The positive correlation was found in eGFR.

Our objective is to analyze the economic burden of chronic kidney disease (CKD) in Vietnam, particularly in District 2 Hospital at Ho Chi Minh City in 2019. This is a descriptive cross-sectional study. The data source is the medical records of the patients. Encoding the data, analyzing treatment cost, regression modeling, and verification were performed using Stata 15 software. Patients with stage 3 CKD account for the highest proportion of the CKD patient population. CKD comorbidities include hypertension, diabetes, cardiovascular disease, and anemia, which increase the treatment fees of patients. Approximately half of the patients with CKD have diabetes or cardiovascular disease. Treatment costs increase as the condition of the patient worsens (except for stage 1 and 2 CKD). The total expenses of all CKD patients in District 2 Hospital were USD 916 423 988.60. Five main factors that affect the treatment fee of a patient: CKD stage, age, gender, and the presence of diabetes, cardiovascular disease, and anemia. The regression model correctly predicts 96% of cases and can explain 64.15% of the fluctuations in costs. The cost of CKD treatment was higher than Vietnam’s per capita GDP in 2019, and the primary factors affecting costs are comorbidities and dialysis.

Threatening Condition

Abstract Background Small-scale studies suggest that hyperkalaemia is a less threatening condition in chronic kidney disease (CKD), arguing adaptation/tolerance to potassium (K+) retention. This study formally evaluates this hypothesis by estimating the distribution of plasma K+ and its association with mortality across CKD stages. Methods This observational study included all patients undergoing plasma K+ testing in Stockholm during 2006–11. We randomly selected one K+ measurement per patient and constructed a cross-sectional cohort with mortality follow-up. Covariates included demographics, comorbidities, medications and estimated glomerular filtration rate (eGFR). We estimated K+ distribution and defined K+ ranges associated with 90-, 180- and 365-day mortality. Results Included were 831 760 participants, of which 70 403 (8.5%) had CKD G3 (eGFR <60–30 mL/min) and 8594 (1.1%) had CKD G4–G5 (eGFR <30 mL/min). About 66 317 deaths occurred within a year. Adjusted plasma K+ increased across worse CKD stages: from median 3.98 (95% confidence interval 3.49–4.59) for eGFR >90 to 4.43 (3.22–5.65) mmol/L for eGFR ≤15 mL/min/1.73 m2. The association between K+ and mortality was U-shaped, but it flattened at lower eGFR strata and shifted upwards. For instance, the range where the 90-day mortality risk increased by no more than 100% was 3.45–4.94 mmol/L in eGFR >60 mL/min, but was 3.36–5.18 in G3 and 3.26–5.53 mmol/L in G4–G5. In conclusion, CKD stage modifies K+ distribution and the ranges that predict mortality in the community. Conclusion Although this study supports the view that hyperkalaemia is better tolerated with worse CKD, it challenges the current use of a single optimal K+ range for all patients.

Background: The outbreak of coronavirus disease 2019 (COVID-19) has attracted global attention. During the lockdown period of COVID-19, follow-up of many patients with chronic disease had been interrupted, which brought severe challenges to better management of their disease. This study aimed at exploring the change of illness, daily life, and psychological responses during the COVID-19 pandemic among chronic kidney disease (CKD) patients.Methods: A total of 612 patients were enrolled in this study; 282 patients were categorized into the CKD stage 1–2 group and 330 patients were categorized into the CKD stage 3–5 group. Among two groups, 168 (27.5%) and 177 (28.9%) patients were female with a median age of 42 and 45, respectively. The study was conducted by collecting the questionnaires in five nephrology centers. The questionnaire consisted of assessment of anxiety by using the Self-Rating Anxiety Scale and the influences of COVID-19, which included basic demographic data, the influences of COVID-19 on illness and daily life, as well as the patients' psychological responses during the epidemic.Results: A total of 612 patients were included and divided into two groups according to eGFR. Ninety-six patients (34%) in the CKD stage 1–2 group and 141 patients (42.7%) in the CKD stage 3–5 group had reduced their follow-up frequency (p = 0.031). More patients with CKD stages 1–2 consulted online (25.9%), p = 0.005. Besides, patients in the CKD stage 3–5 group tended to be more anxious about follow-up (p = 0.002), fearful of being infected with COVID-19 (p = 0.009), and more likely to feel symptoms getting worse (p = 0.006). The standard scores of SAS were 48.58 ± 7.082 and 51.19 ± 5.944 in the CKD stage 1–2 group and the CKD stage 3–5 group, respectively (p < 0.001). There were significant differences in the severity of anxiety (p = 0.004).Conclusion: COVID-19 had a greater impact on patients with CKD stages 3–5 than those with stages 1–2 in terms of illness, daily life, and psychological disorder. Patients with CKD stages 3–5 were more anxious during the COVID-19 pandemic.

Low heart rate variability (HRV) is independently associated with increased risk of sudden cardiac death (SCD) and all cardiac death in haemodialysis patients. Long chain n-3 polyunsaturated fatty acids (LC n-3 PUFA) may exert anti-arrhythmic effects. This study aimed to investigate relationships between dialysis, sleep and 24 h HRV and LC n-3 PUFA status in patients who have recently commenced haemodialysis. A cross-sectional study was conducted in adults aged 40–80 with chronic kidney disease (CKD) stage 5 (n = 45, mean age 58, SD 9, 20 females and 25 males, 39% with type 2 diabetes). Pre-dialysis blood samples were taken to measure erythrocyte and plasma fatty acid composition (wt % fatty acids). Mean erythrocyte omega-3 index was not associated with HRV following adjustment for age, BMI and use of β-blocker medication. Higher ratios of erythrocyte eicosapentaenoic acid (EPA) to docosahexaenoic acid (DHA) were associated with lower 24 h vagally-mediated beat-to-beat HRV parameters. Higher plasma EPA and docosapentaenoic acid (DPAn-3) were also associated with lower sleep-time and 24 h beat-to-beat variability. In contrast, higher plasma EPA was significantly related to higher overall and longer phase components of 24 h HRV. Further investigation is required to investigate whether patients commencing haemodialysis may have compromised conversion of EPA to DHA, which may impair vagally-mediated regulation of cardiac autonomic function, increasing risk of SCD.

Abstract Background The cardiovascular mortality of patients with chronic kidney disease (CKD) is 2–10 times higher than in the average population. Purpose To estimate the prevalence of abnormal cardiac function or structure across the stages CKD 1 to 5nonD. Method Prospective cohort study. Patients with CKD stage 1 to 5 not on dialysis, aged 30 to 75 (n=875) and age-/sex-matched controls (n=173) were enrolled consecutively. All participants underwent a health questionnaire, ECG, morphometric and blood pressure measurements. Blood and urine were analyzed. Echocardiography was performed. Left ventricle (LV) hypertrophy, dilatation, diastolic and systolic dysfunction were defined according to current ESC guidelines. Results 63% of participants were men. Mean age was 58 years (SD 12.6 years). Mean eGFR was 46.7 mL/min/1,73 m (SD 25.8) for patients and 82.3 mL/min/1,73 m (SD 13.4) for controls. The prevalence of elevated blood pressure at physical exam was 89% in patients vs. 53% in controls. Patients were more often smokers and obese. Left ventricular mass index (LVMI) was slightly, albeit insignificantly elevated at CKD stages 1 & 2 vs. in kontrols: 3.1 g/m2, CI: −0.4 to 6.75, p-value 0.08. There was no significant difference in LV-dilatation between patients and controls. Decreasing diastolic and systolic function was observed at CKD stage 3a and later: LVEF decreased 0.95% (CI: −1.5 to −0.2), GLS increased 0.5 (CI: 0.3 to 0.8), and OR for diastolic dysfunction increased 3.2 (CI 1.4 to 7.3) pr. increment CKD stage group. Conclusion In accordance to previous studies, we observe in the CPHCKD cohort study signs of early increase of LVMI in patients with CKD stage 1 & 2. Significant decline in systolic and diastolic cardiac function is apparent already at stage 3 CKD. Figure 1.

Background: Many drugs should be avoided or require dose-adjustment in chronic kidney disease (CKD). Previous estimates of potentially inappropriate prescribing rates have been based on data on a limited number of drugs and mainly in secondary care settings. Aim: To determine the prevalence of contraindicated and potentially inappropriate primary care prescribing in a complete population of people with CKD. Method: Cross-sectional study of prescribing patterns in a complete geographical population of people with CKD defined using laboratory data. Drugs were organised by British National Formulary advice. Contraindicated (CI) drugs: “avoid”. Potentially high risk (PHR) drugs: “avoid if possible”. Dose inappropriate (DI) drugs: dose exceeded recommended maximums. Results: 28,489 people with CKD were included in analysis, of whom 70.0% had CKD 3a, 22.4% CKD 3b, 5.9% CKD 4, and 1.5% CKD 5. 3.9% (95%CI 3.7-4.1) of people with CKD stages 3a-5 were prescribed one or more CI drug, 24.3% (95%CI 23.8-24.8) PHR drug, and 15.2% (95% CI 14.8-15.62) DI drug. CI drugs differed in prevalence by CKD stage, and were most commonly prescribed in CKD stage 4 with a prevalence of 36.0% (95%CI 33.7–38.2). PHR drugs were commonly prescribed in all CKD stages ranging from 19.4% (95%CI 17.6-21.3) in stage 4 to 25.1% (95%CI 24.5–25.7) in stage 3b. DI drugs were most commonly prescribed in stage 4, 26.4% (95%CI 24.3-28.6). Conclusion: Potentially inappropriate prescribing is common at all stages of CKD. Development and evaluation of interventions to improve prescribing safety in this high-risk populations are needed.

Aim. To conduct comparative analysis of height, weight and body mass index in children with stages 1 to 3 of chronic kidney disease (CKD) caused by recurrent urinary tract infection due to congenital anomalies of kidney and urinary tract.Methods. The study was performed on 210 children: 110 patients examined in 2001-2002 (group 1) and 100 children examined in 2011-2012 (group 2). Stage 1 of CKD was observed in 94 (85.4%) children in group 1 and in 93 (93%) in group 2, stage 2 - in 16 (14.6%) and 7 (7%) patients, respectively. From both groups patients matched by sex, age, diagnosis and social status were selected: 20 patients with stage 1, 19 children with stage 2; in addition, 6 children with stage 3 were examined.Results. Nowadays children with CKD stage 1 are taller compared to patients of the beginning of the XXI century (Z-score: -0.14±1.43 and 0.20±0.98 respectively, p=0.01). Significant differences in weight were found in children with stage 1 in 2011-2012 compared to the patients in 2001-2002 (0.18±0.46 and 0.78±1.19 for groups 1 and 2, respectively, р=0.026). A tendency towards decrease of average height in children with stage 3 is observed compared to patients with stage 1, i.e. due to the progression of the disease.Conclusion. The data obtained reflect modern tendencies towards increase of children height and weight. No significant differences were found in physical development parameters of children with stages of chronic kidney disease 1 and 2 examined at the same time period but a tendency towards children’s height decrease from stages 1 to 3 of CKD of non-glomerular etiology was revealed.
