Breath Ammonia Is a Useful Biomarker Predicting Kidney Function in Chronic Kidney Disease Patients

Chronic kidney disease (CKD) is a public health problem and its prevalence has increased worldwide; patients are commonly unaware of the condition. The present study aimed to investigate whether exhaled breath ammonia via vertical-channel organic semiconductor (V-OSC) sensor measurement could be used for rapid CKD screening. We enrolled 121 CKD stage 1–5 patients, including 19 stage 1 patients, 26 stage 2 patients, 38 stage 3 patients, 21 stage 4 patients, and 17 stage 5 patients, from July 2019 to January 2020. Demographic and laboratory data were recorded. The exhaled ammonia was collected and rapidly measured by the V-OSC sensor to correlate with kidney function. Results showed no significant difference in age, sex, body weight, hemoglobin, albumin level, and comorbidities in different CKD stage patients. Correlation analysis demonstrated a good correlation between breath ammonia and blood urea nitrogen levels, serum creatinine levels, and estimated glomerular filtration rate (eGFR). Breath ammonia concentration was significantly elevated with increased CKD stage compared with the previous stage (CKD stage 1/2/3/4/5: 636 ± 94; 1020 ± 120; 1943 ± 326; 4421 ± 1042; 12781 ± 1807 ppb, p < 0.05). The receiver operating characteristic curve analysis showed an area under the curve (AUC) of 0.835 (p < 0.0001) for distinguishing CKD stage 1 from other CKD stages at 974 ppb (sensitivity, 69%; specificity, 95%). The AUC was 0.831 (p < 0.0001) for distinguishing between patients with/without eGFR < 60 mL/min/1.73 m2 (cutoff 1187 ppb: sensitivity, 71%; specificity, 78%). At 886 ppb, the sensitivity increased to 80% but the specificity decreased to 69%. This value is suitable for kidney function screening. Breath ammonia detection with V-OSC is a real time, inexpensive, and easy to administer measurement device for screening CKD with reliable diagnostic accuracy.

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 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.

Abstract Background and Aims Changes in dietary phosphorus regulate serum FGF-23, parathyroid hormone, 1,25(OH)(2)D and Klotho concentrations . Cardiovascular disease (CVD) is the principal killer of patients with chronic kidney disease and hyperphosphetemia is a potent risk factor it. Of many causative factors for CVD in CKD, dietary interventions involving restriction of dietary phosphorous intake can help reduce onset of CVD at early stages of CKD with other corrective measures. Muscle wasting is a consequence of uremic syndrome which alters body composition. The aim of the study was to study effect of dietary phosphorous restriction on FGF-23, iPTH, Klotho, 1,25(OH)(2)D and body composition in chronic kidney disease patients. Method This is a longitudinal study with 12 months intervention, approved by Ethics Committee of the institute. A total 132 subjects were recruited (66 healthy controls, 66 CKD patient. of 66 patients 33 were in CKD stage 1 and 33 in stage 2. GFR was calculated with the help of MDRD formula. Biochemical parameters of subjects were evaluated at baseline, 6 and 12 months along with the anthropometric measurements (body weight, height, mid upper arm circumference (MUAC), and skin folds). Three days dietary recall was taken to evaluate energy, protein and phosphorous intake. CKD patients whose dietary phosphorous intake was more than 1000 mg/day, were given intense dietary counseling and prescribed dietary modifications by restricting dietary phosphorous between 800-1000 mg/day. Results The mean age of controls and patients was 37.01±9.62 and 38.27±12.06 and eGFR of 136.94±11.77 and 83.69±17.37 respectively. One way ANOVA showed significant difference among controls and the study groups in hemoglobin (p<0.001), s albumin (p<0.001), FGF-23 (p<0.001), klotho (p<0.001), urinary protein (p<0.001) and Nephron Index (p<0.001).The mean energy intake (p = 0.001) and dietary phosphorous intake (p<0.001) of the CKD patients decreased significantly with the decline in the renal function along with the anthropometric measures i.e. BMI (p = 0.041),WHR (p = 0.015) and all four skin folds (p<0.001). On applying Pearson’s correlation, eGFR correlated negatively with urinary protein (-0.739, 0.000), FGF-23 (-0.679, 0.000) and serum phosphorous (-0.697, 0.000) and positively with klotho (0.872, 0.000). FGF-23 correlated negatively with klotho (-0.742, 0.000). Dietary phosphorous was found to be positively correlated with urinary protein (0.496, 0.000), serum phosphorous (0.680, 0.000) and FGF-23 (0.573, 0.000) and negatively with Klotho (-0.602, 0.000). Nephron index revealed a positive correlation with eGFR (0.529, 0.000). Urinary protein correlated negatively with klotho (-0.810, 0.000). A multiple linear regression was run to predict eGFR from anthropometric variables such as BMI, WHR, MUAC, skin folds thickness and handgrip strength. All anthropometric variables predicted decline in eGFR (p<0.05, R2 =0.223). At 6 and 12 months; repeated ANOVAs analysis showed a statistically significant difference in serum creatinine (p=0.000), serum phosphorous (p=0.000), FGF-23(p=0.000) and klotho (p=0.000). Conclusion Elevated levels of FGF-23 and decreased Klotho levels, with the moderate decline in renal function improved with the restricted phosphorous diet at 6 and 12 months emphasizing the importance of phosphorus restriction at an early stage.

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.

BACKGROUND: Heart failure (HF) and Chronic kidney disease (CKD) are major public health problems that often co-exist with a resultant high mortality and morbidity. Most of the studies evaluating their reciprocal prognostic impact have focused on mortality in majority populations. There is limited literature on the impact of CKD on HF morbidities in ethnic minorities. AIMS: Our study seeks to compare HF outcomes in patients with or without CKD in an African-American predominant cohort. METHODS: We obtained data from the NGH at Meharry Heart Failure Cohort; a comprehensive retrospective HF database comprised of patient care data (HF admissions, non-HF admissions, and emergency room visits) were assessed from January 2006 to December 2008. The study group consist of 306 subjects with a mean age of 65±15 years. 81% were African-American (AA), 19% Caucasian and 48.5% are females. Following the NKF KDOQI guidelines, 5 stages of CKD were outlined based on GFR. RESULTS: The overall prevalence of CKD in this population is 54.2%. CKD stage 1 was most prevalent with 45.8%, prevalence for stages 2-5 are 21.6%, 18.3%, 9.5% and 4.9% respectively. The comparison of the mean of ER visits, non HF hospitalizations and HF hospitalizations between normal and CKD patients was done using independent t-test and showed no significant difference in the mean number of ER visits (p=0.564), or HF hospitalizations(p=0.235). However, there is a statistically significant difference in the mean number of non -HF hospitalizations between normal and CKD patients (p=0.031). CONCLUSION: This study shows that the prevalence of CKD in this minority -predominant HF cohort is similar to prior studies in majority populations. However, only the non-HF hospitalizations were significantly increased in the CKD group. Future prospective studies will be needed to define the implications of this in the management of HF patients with CKD.

ObjectivesMagnesium has been ‘the forgotten ion’ for many years. Over the past decade, however, the role of magnesium in essential physiological functions and several illness conditions have been elucidated. Nevertheless, the investigation of magnesium in cats with chronic kidney disease (CKD) and nephrolithiasis is yet to be determined. The purpose of this study was to investigate whether CKD cats with nephrolithiasis have changes in total serum magnesium concentrations, and whether magnesium disorders may be associated with other electrolyte disturbances, as well as with prognosis. We also aimed to evaluate whether total serum magnesium concentration differs between CKD cats with and without nephrolithiasis.MethodsTotal serum magnesium concentrations were assessed in 42 cats with CKD with stage 1–4 nephrolithiasis. The correlation between magnesium and other electrolytes, as well as Kaplan–Meier survival analysis, were performed. We also selected 14 control cats with CKD without nephrolithiasis age-matched with 14 cats with CKD with nephrolithiasis.ResultsHypermagnesemia was observed in 16/42 (38.1%) and hypomagnesemia in 6/42 (14.3%) cats. Serum magnesium abnormalities were observed in cats of all stages, and marked hypermagnesemia was noted in cats with stage 4 CKD with nephrolithiasis ( P <0.001). There was a negative correlation between total serum magnesium and ionized calcium ( r = −0.64; P <0.01), and a positive correlation between total serum magnesium and serum phosphorus ( r = 0.58, P = 0.01). Cats with CKD with nephrolithiasis and hypomagnesemia or hypermagnesemia had higher mortality than those with normal total serum magnesium concentration ( P <0.01), regardless of CKD stage. There was no difference in total serum magnesium concentration between CKD cats with and without nephrolithiasis.Conclusions and relevanceCats with CKD with nephrolithiasis have magnesium abnormalities. Hypomagnesemia and hypermagnesemia were associated with an increase in mortality, and thus total serum magnesium abnormalities may be used as prognostic factors in these cases.

The Relationship

Abstract Background Occurrence of cardiovascular disease (CVD) in the setting of chronic kidney disease (CKD) can be described as a “cruel alliance”, with CVD responsible for about half of all deaths among CKD patients. Chronic kidney disease patients are more likely to die from CVD than progress to end stage kidney disease (ESKD). Dyslipidaemia, a known traditional risk factor for CVD, is highly prevalent among CKD patients and with an even higher frequency among ESKD patients on dialytic therapies. Prolonged exposure of continuous ambulatory peritoneal dialysis (CAPD) patients to high glucose concentrations in CAPD fluid have been associated with increased risk of cardiovascular events. In this study, we investigated the relationship of atherosclerotic vascular disease (AsVD) to clinical and echocardiographic parameters among black South Africans with CKD (stage 3) and ESKD on CAPD and haemodialysis (HD). Methods This was a cross-sectional study of 40 adult (18–65 years) non-diabetic CKD patients (kidney disease outcome quality initiative [KDOQI] stage 3), 40 ESKD patients on CAPD, 40 ESKD patients on HD and 41 age and sex-matched healthy controls. An interviewer-administered questionnaire was used to obtain information on participants’ sociodemographic and cardiovascular risk factors. Anthropometric parameters were measured. Serum blood samples were analysed for creatinine, albumin and lipid profile; lipoprotein ratios, Framingham’s risk score and the 10-year risk of developing coronary heart disease (CHD) were calculated. Echocardiography was performed on all patients and carotid intima media thickness (CIMT) was measured in both right and left carotid arteries at 1 cm proximal to the carotid bulb. Spearman’s rank correlation and binary logistic regression were conducted to determine the relationship of AsVD to clinical and echocardiographic parameters. Results Atherosclerotic vascular disease was most prevalent among ESKD patients on CAPD (70%, n = 28/40). Chronic kidney disease and HD patients exhibited a similar prevalence (47.5%, n = 19/40), while the prevalence in controls was 17.1% (n = 7/41). Presence of AsVD was associated with significantly older age, higher waist hip ratio (WHR), left ventricular mass index (LVMI) and Framingham’s 10-year risk of developing CHD. Significant differences in clinical and echocardiographic parameters were observed when the study groups were compared. Age and LVH independently predicted AsVD. Conclusion Atherosclerotic vascular disease was more prevalent among CAPD patients compared to pre-dialysis CKD and HD patients. Among all lipoprotein ratios assessed, non-HDL-C showed the most consistent significant difference between the groups. Age (> 40 years) and presence of LVH were independent predictors of AsVD.

Abstract Background Arterial damage in chronic kidney disease (CKD) is characterized by aortic stiffness. This is seen in elderly patients with advanced CKD. The association between arterial stiffness and early CKD is not well established. Objective: We aimed to study arterial stiffness using pulse wave velocity (PWV) among patients with chronic kidney disease (CKD) stage 2 to 4 and normal renal function in younger-age population. Design and Method: Patients with confirmed CKD stage 2 to 4 were recruited from various clinics from Universiti Teknologi MARA Medical Center, Sungai Buloh, Malaysia from 1st August 2015 until 31st January 2018. Sociodemographic and anthropometric indices were recorded on recruitment. Each patient underwent carotid-femoral (aortic) PWV measurement to determine arterial stiffness. PWV is determined using a one-probe device (SphygmoSore XCEL). Results: 87 patients with CKD stage 2–4 and 87 control patients were recruited. The mean age was 47 ± 5.4 years. CKD patients had a higher mean PWV (7.8 m/s ± 1.7) than healthy controls (5.6 m/s ± 1.0) (p < 0.001, 95% CI –2.59, –1.77). There was significant difference of mean PWV between control (5.6 m/s ± 1.0) and CKD stage 2 (7.6 m/s ± 1.5) (p < 0.001, 95% CI –2.40, –1.49). Our results showed a stepwise increase in PWV from control subjects, CKD stage 2 through stage 4 (p < 0.001). The mean difference of PWV between CKD stage 2 (7.6 m/s, ± 1.5) and stage 4 (9.0 m/s, ± 0.8) was 1.43 (p < 0.001, 95% CI –2.50, -0.35). There was significant difference of mean PWV between diabetes mellitus (DM) (8.2 m/s ± 1.8) and non-DM (7.3 m/s ± 1.3) patients with CKD stage 2–4 (p = 0.022, 95% CI –1.50, –0.12). Mutiple linear regression analysis showed only age (β = 0.078, p = 0.014), mean arterial pressure (MAP) (β = 0.031, p = 0.007) and diuretics usage as the combination antihypertensive medication (β = 0.839, p = 0.018) were independently associated with PWV (r2 = 0.249, p < 0.001). Conclusions: This study shows that arterial stiffness as assessed by PWV occurs early in CKD patient and increased arterial stiffness occurs in parallel with decline of glomerular filtration rate in patients with mild-to-moderate CKD of younger age population.

Chronic kidney disease (CKD), a damaged condition of the kidneys, is a global public health problem that can be caused by diabetes, hypertension, and other disorders. Recently, the MANBA gene was identified in CKD by integrating CKD-related variants and kidney expression quantitative trait loci (eQTL) data. This study evaluated the effects of MANBA gene variants on CKD and kidney function-related traits using a Korean cohort. We also analyzed the association of MANBA gene variants with kidney-related traits such as the estimated glomerular filtration rate (eGFR), and blood urea nitrogen (BUN), creatinine, and uric acid levels using linear regression analysis. As a result, 14 single nucleotide polymorphisms (SNPs) were replicated in CKD (p < 0.05), consistent with previous studies. Among them, rs4496586, which was the most significant for CKD and kidney function-related traits, was associated with a decreased CKD risk in participants with the homozygous minor allele (CC), increased eGFR, and decreased creatinine and uric acid concentrations. Furthermore, the association analysis between the rs4496586 genotype and MANBA gene expression in human tubules and glomeruli showed high MANBA gene expression in the minor allele carriers. In conclusion, this study demonstrated that MANBA gene variants were associated with CKD and kidney function-related traits in a Korean cohort.

IntroductionAnemia is the most common occurrence in chronic kidney disease undergoing hemodialysis therapy. In the condition of chronic kidney disease, the decline in kidney function can occur slowly and chronically until the kidneys do not function at all. Hemodialysis is one of the therapies used to replaced kidney function. During hemodialysis, a decrease in hemoglobin levels often occurs, this is due to the disruption of the hormon erythropoietin. Objective:determine the differences in hemoglobin levels in patients with chronic kidney disease before and after hemodialysis at Bhayangkara TK. I Raden Said SukantoHospital. Method: The design of this research is cross sectional using secondary data and the sampling technique of this research was random sampling with a total of 133 patients. Result: The normality test was carried out first using the Kolmogorov-Smirnova test which showed the results were not normally distributed with a sig value of 0.001. the next test was the Wilcoxon test with a sig (2-tailed_ value of 0.002 with an average hemoglobin level of 8,81 g/dL before hemodialysis and 9,09 g/dL after hemodialysis. Conclusion:Based on the results of the study means that there is a significant difference in a patient with chronic kidney failure before and after hemodialysis.
