CLINICAL PROFILE OF MINERAL BONE DISORDERS (RENAL OSTEODYSTROPHY) IN CHRONIC KIDNEY DISEASE PATIENTS

Objective: The objective of the study was to evaluate the clinical profile of mineral bone disorders (renal osteodystrophy) in chronic kidney disease (CKD) patients. Methods: A retrospective study was performed involving 100 patients above 15 years of age with previously diagnosed chronic renal failure. A series of tests such as biochemical, radiological, and arterial calcifications were monitored. The mean age of subjects in our study was 52.54 years. Results: Biochemical tests revealed that hypocalcemia was present in 54% of the patients, and hyperphosphatemia was seen in 84% of the participants, while only 22% of the participants had high alkaline phosphate (ALP) levels. Radiological tests revealed that 39 patients had aortic calcification, 42 patients had radial artery calcification, and 27 patients had both. Subperiosteal resorption was seen on 29 participants. The majority of the vascular calcification and subperiosteal resorption was seen in patients with CKD Stage 5, and both aortic and radial artery calcifications were significantly associated with subperiosteal bone resorption. Conclusion: The results point toward a high prevalence of derangement in the mineral, vascular and valvular calcifications. Serum total ALP can serve as a biochemical marker to identify a pattern of bone turnover where intact parathyroid hormone is not available. The results highlight that serum phosphorus and Ca × P product levels were significantly associated with both aortic and radial artery calcifications. There was no significant association of these calcifications with serum calcium and ALP levels.

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.

The Impact

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.

Chronic Use

Abstract Background Renin–angiotensin–aldosterone system (RAAS) inhibitors provide significant cardiorenal benefits with improved long-term outcomes for patients. This is most significant for patients receiving maximal RAAS inhibition, but some patients are unable to tolerate this therapy because of hyperkalaemia. Recently published National Institute for Health and Care Excellence (NICE) technology appraisal guidance recommended using sodium zirconium cyclosilicate (SZC) and patiromer for patients with chronic kidney disease (CKD) stage 3b to 5 or heart failure with reduced ejection fraction, who are not taking an optimised dosage of RAAS inhibitor because of hyperkalaemia. Objective Determine the impact of a locally produced guideline on effective implementation of NICE recommendation for use of SZC or patiromer to help maximise inhibition of the renin–angiotensin–aldosterone system within the general nephrology clinic. Methods A local guideline to practically support the implementation of recommendations made by NICE in the chronic use of new potassium binders was produced. One hundred sequential patients in a general nephrology clinic with non-immune chronic kidney disease (CKD 3 to 5) had their electronic records reviewed. Those with an indication for RAAS inhibition were identified. Results Of the 100 consecutive patients audited, 46 were female and 54 were male. The mean age of these patients was 64 and the mean estimated glomerular filtration rate (eGFR) was 33. Sixty-eight patients had an indication for being on RAAS inhibition with only 10 on maximal doses. Of the remaining 58 patients, 26 (45%) were limited by hyperkalaemia. Of these 26 patients, 12 of these patients (46%) had hyperkalaemia associated with an episode of acute kidney injury (AKI). Therefore, 14% of patients attending a general nephrology clinic were identified suitable for SZC and patiromer. Conclusions A significant proportion (14%) of unselected patients attending a general nephrology clinic were not on optimum RAAS inhibition due to hyperkalaemia. These patients would meet the criteria established within a working guideline for the implementation of the chronic use of SZC or patiromer and are likely to attain prognostic long-term benefit by using these new potassium binders to maximise RAAS inhibition. This analysis has implications for renal centres across the UK.

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.

Background: Anemia and mineral bone disorders (MBD) accompany chronic kidney disease (CKD) and worsen as CKD progresses. Different biochemical parameters of CKD-MBD have been associated with anemia of CKD but are less well evaluated in low resource settings. In this study, we evaluated the role CKD-MBD disorders as a cause of anemia in CKD non-dialysis patients. Methods: This cross-sectional study recruited 115 patients with CKD who attended outpatient department (OPD) of Nephrology in BIRDEM General Hospital between January and June 2019. Patients, who were on iron, erythropoietin, calcium or vitamin D therapy in any form within the preceding 3 months and patients with known parathyroid disorders, metabolic bone diseases or anemia with definite etiology were excluded. Each patient’s demographic, clinical and biochemical parameters were recorded. Associations between anemia and serum levels of calcium (corrected), phosphate, parathyroid hormone (PTH), 25-hydroxy vitamin D [25(OH)D] and alkaline phosphatase were evaluated. Results: Total patients were 115 including 71 (61.7%) females. Mean age was 57.8 years. Most patients were in CKD stage 4 (43, 37.4%) and 5 (45, 39.1%). Mean duration of diabetes and hypertension were 12.7 and 7.2 years respectively. Mean serum creatinine (mg/dL), hemoglobin (gm/dL), calcium (mg/dL), albumin (gm/L), phosphate (mg/dL), alkaline phosphatase (U/L), PTH (pg/mL) and 25(OH)D (ng/mL) were 3.1, 10.5, 8.7, 37.9, 4.0, 119.1, 211.1 and 15.1 respectively. Hemoglobin in CKD stages 3-5 pre-dialysis patients had positive correlation with calcium and 25(OH)D and negative correlation with phosphate, alkaline phosphatase and PTH. Among these parameters of CKD-MBD, correlation with alkaline phosphatase was significant (r=-0.352, p=0.001) Conclusion: Anemia in CKD patients is multifactorial and this study concludes that CKD-MBD is yet another entity contributing to anemia in such pre-dialysis patients.

Abstract Objectives To compare the proportion of sensorineural hearing impairment (SHI) among patients of chronic kidney disease (CKD) stages 3&4 with CKD stage 5. Materials and Methods This is a cross-sectional study of 30 patients with CKD stages 3 and 4 and 30 patients in stage 5. All patients had an audiological evaluation with pure tone audiometry. Results Our study had 49 males (82%) and 11 females (18%), with the age ranging from 20 to 60 years (mean: 45.13 years). The mean SHI values in stage 3&4 were 28.44 dB and in CKD stage 5 was 31.22 dB. In the right ear, the mean hearing loss in stage 3, stage 4, and stage 5 was 28.17 dB, 28.67 dB, and 31.84 dB, respectively. In the left ear, the mean SHI values in stage 3, stage 4, and stage 5 were 27.05 dB, 31.89 dB, and 30.61 dB, respectively.The mean SHI in stage 3&4 for age group 20 to 30 years was 13.66 dB, for 31 to 40 years was 26.33 dB, for 41 to 50 years was 35.18 dB, for 51 to 60 years was 37.12 dB. The mean SHI in stage 5 for the age group of 20 to 30 years was 16.48 dB, for 31 to 40 years was 28.29 dB, for 41 to 50 years was 31.82 dB, for 51 to 60 years was 34.35 dB. There was a significant correlation between hearing loss and CKD with respect to age (p < 0.001). The duration of renal illness and associated comorbidities was not a significant contributor to hearing loss in our study (p > 0.05). Conclusion As per our study, with progression in the stage of chronic kidney disease, the hearing loss also increased indicating a possible link between the two. We also noted that the hearing loss increased with the increasing age.

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.

Background: The present study was conduct in Motilal Nehru Medical College, Swaroop Rani Nehru Hospital Prayagraj, a tertiary care center and data was collected over a period from January 2019 to April 2020. All 78 patients of CKD attending OPD & IPD of General Medicine and Nephrology, diagnosed by suggestive symptoms and conrmed by physical examination and laboratory investigations were taken , Among the subjects, those having NAFLD were grouped as cases. Patients of Chronic Kidney disease not having NAFLD were grouped as controls. Aim & Objective: To study the prevalence of NAFLD in patients of CKD and establish the association between NAFLD and CKD by studying the effect of NAFLD on eGFR. Methodology: This was a 16 month case control study. Total 78 patients with age 18-65 years , Either sex with Chronic kidney disease diagnosed by USG, KFT, physical examination and having NAFLD Patients with known diagnosis of metabolic syndrome, diabetes and/or hypothyroidism. Those on hepatotoxic medication (amiodarone, barbiturates, glucocorticoids, etc.). The data so collected was entered into computer using Microsoft Excel 2013 software and was subjected to statistical analysis. Result : The ndings of present study thus reafrm the observations of previous studies that highlight a high prevalence of NAFLD in CKD patients and link it to the deranged metabolic factors. In present study we could not found a convincing evidence supporting a relationship between NAFLD and its severity with progression of CKD, probably owing to three major factors – rst, owing to Discussion 71 limitation of study population in only CKD stage 3 and secondly, owing to absence of retrospective data tracing the time of development of NAFLD in these patients and thirdly, inability to carry out long-time follow-up of patients. In present study, though minor changes in eGFR values in patients were seen, however, during the limited period of follow-up no shift from Stage 3 to other stages of CKD was observed. All the patients were regular in follow-up and had a good medical compliance and in general did not show a phenomenal deterioration in renal function within the short span of study. Keeping in view these limitations, further studies are recommended on a larger sample size with inclusion of patients from different stages of CKD spanning over a longer duration of follow-up to see whether NAFLD presence and its severity has a relationship with long-term progression of CKD. Conclusion: The present study showed that, CKD patients had a high prevalence of NAFLD. The ndings also show that FIB-4 scores are useful noninvasive methods for detection of NAFLD in CKD patients. The ndings showed a possible signicant association between NAFLD and lower eGFR rates. One of the limitations of the present study was presence of only Stage 3 CKD patients, owing to which the linear correlations between eGFR and NAFLD severity could not be assessed properly. Further studies on larger sample size with inclusion of patients with other CKD stages too are recommended.
