  • Serum Sulphate Levels in Hemodialysis Patients

    • Abstract: Objective. Sulphur, similar to phosphorus, is easily attached to organic compounds. The inadequate elimination of sulphate may cause high sulphate concentrations in hemodialysis (HD) patients because sulphate is low in free form in plasma. Although we are well aware of the accumulation of phosphorus in chronic dialysis patients, we do not have an adequate knowledge database about the sulphur compounds. This study was designed to determine the level of sulphate in hemodialysis patients. Materials and Methods. Ninety-four prevalent HD patients and 33 patients without renal failure were included in the study. The serum inorganic sulphate levels were measured by turbidimetric technique. Moreover, the serum level of urea, creatinine, albumin, calcium, phosphorus, and parathyroid hormone concentrations was simultaneously recorded. Results. Mean levels of plasma sulphate were significantly higher (0.56 ± 0.17 mM vs 0.31 ± 0.13 mM, ) in HD patients. Serum sulphate level correlated with patient’s age, serum albumin, serum BUN and creatinine, and serum phosphorus level in HD patients. Serum sulphate levels were not associated with serum parathyroid hormone levels. Conclusion. Serum sulphate levels were approximately twofold higher in HD patients than in the normal control group. Inorganic sulphate does not seem to accumulate in long-term dialysis patients, and mild increased serum levels of sulphate has no poor clinical outcome in these patients.

  • Etiology of Renal Replacement Therapy in Iran

    • Abstract: Introduction. End-stage renal disease (ESRD) is one of the most common life-threatening diseases. In the past two decades, several factors were held responsible as the cause of this condition. The present study aimed to determine the causes of ESRD in the province of Khorasan Razavi, Iran. Materials and Methods. This cross-sectional study was conducted on 2404 ESRD patients who referred to 39 hemodialysis centers in Khorasan Razavi province, Iran, and were registered in the Mashhad University of Medical Sciences (MUMS), between 2000 and December 2018. Sociodemographic data and causes of ESRD were extracted from data registry. Results. The mean age at onset of hemodialysis for 2404 patients was 52.8 ± 16.4 years, and 57.1% of the patients were male. Clinical profile of hypertension (28.3%) and diabetes mellitus (24.8%) were the most common known causes of ESRD in our patients. Hypertension was more prevalent in male patients compared with females (30 vs 25%, respectively) while diabetes was more prevalent in females compared with males (25.4 vs 24.4%, respectively), . Educational level was significantly associated with the cause of ESRD (). Age of onset of ESRD in hypertensive patients was significantly lower compared with diabetic patients (51.5 ± 16.3 vs 58.28 ± 12.9 years, respectively; ).Conclusions. In the current study, the most common causes of ESRD were hypertension and diabetes mellitus. Primary prevention of hypertension and diabetes and proper treatment must be considered to reduce the burden of ESRD in Iran.

  • The Role of Cathepsin B in Peritoneal Fibrosis due to Peritoneal Dialysis

    • Abstract: Glucose-containing peritoneal dialysis (PD) solution causes peritoneal fibrosis (PF) characterized by accumulation of extracellular matrix (ECM) in the submesothelial layer. Cathepsin B is a lysosomal cysteine protease that degrades ECM, but its role in the PF remains unclear. Thus, we investigated the role of cathepsin B in PF. Procathepsin B was measured in the 73 PD effluents of 68 patients. Procathepsin B and cathepsin B after exposure of glucose and the effects of cathepsin B on the expression of matrix metalloproteinases (MMPs), tissue inhibitor of metalloproteinases (TIMPs), and urokinase-type plasminogen activator (uPA) were measured in the supernatant of cultured human peritoneal mesothelial cells (HPMCs). The effect of cathepsin B and its inhibitor, cystatin C, on PF was investigated in the murine model. Procathepsin B was measured at 3.6 μg/L in serum and 5.4 μg/L in PD effluent and positively correlated to the cancer antigen (CA) 125. The treatment with 4.25% glucose increased procathepsin B by 3.1-fold and cathepsin B by 5.9-fold in the HPMCs. Cathepsin B induced the secretion of MMP-1, -2, and -3 and TIMP-1 in the HPMCs, but uPA was not excreted. In the PF murine models, cathepsin B reduced the thickness of the submesothelial layer and cystatin C attenuated the effect of cathepsin B. HPMCs secrete cathepsin B with exposure of PD solution, and cathepsin B might help protect against PF.

  • Mechanism Underlying Selective Albuminuria in Minimal Change Nephrotic

    • Abstract: As water and solutes are filtered through the slit membrane, it is an a priori concept that a slit membrane is an essential filtration barrier for proteins, including albumin. However, in cases of minimal change nephrotic syndrome, the number of slit membranes is reduced by the foot process effacement and tight junction-like cell adhesion. Furthermore, albumin endocytosis is enhanced in the podocytes under condition of minimal change disease, and albumin is selectively transported by the albumin receptor FcRn. Suppressing the endocytosis of albumin with anti-FcRn antibody decreases the urinary protein level. The expression of motor molecules, such as cytoplasmic dynein 1 and myosin IX, is increased in the podocytes under conditions of minimal change nephrotic syndrome, suggesting the enhanced transport of vesicles containing albumin. Podocyte vesicle transport may play an important role in the pathology of selective albuminuria in cases of nephrotic syndrome.

           Chronic Kidney Disease at Jimma University Medical Center, Jimma Zone,
           Jimma, Southwest Ethiopia: A Hospital-Based Prospective Observational

    • Abstract: Background. There is an alarming rise of chronic kidney disease prevalence globally associated with significant morbidity and mortality necessitating special attention as one of the major growing public health problems. Medication-related problems are common in hospitalized patients including chronic kidney disease and may lead to increase hospital stay and health care cost and augment the risk of morbidity and mortality. Objective. To determine prevalence of medication-related problems and associated factors among chronic kidney disease patients admitted to Jimma University Medical Center from April to September 2018. Methods. A hospital-based prospective observational study was conducted among 103 chronic kidney disease patients admitted to Jimma University Medical Center from April to September 2018. Data regarding patient characteristics, medications, diagnosis, length of hospitalization, and laboratory results were collected through review of patients’ medical charts. Data were analyzed by using Statistical Package for the Social Sciences (SPSS) version 21.0. Univariate and multivariate logistic regression was utilized to assess the associations between dependent and independent variables. Statistical significance was considered at value

  • High Incidence of Moderately Reduced Renal Function and Lead
           Bioaccumulation in Agricultural Workers in Assin South District, Ghana: A
           Community-Based Case-Control Study

    • Abstract: Background. The quest to enhance agricultural productivity and crop yields has led to increased use of agrochemicals on a global scale. Long-term use of these agrochemicals may be associated with adverse health implications. Objective. To assess haematological indices, renal function, heavy metal bioaccumulation in farmers and sprayers, and their use of personal protective equipment (PPE). Materials and Methods. This community-based case-control study was conducted from January 2018 to June 2018 in the Assin South District, Central Region, Ghana. A total of 144 participants were conveniently sampled: 83 agricultural workers (cases) and 61 indigenes with no direct exposure to agrochemicals (controls). Structured questionnaire was used to obtain demographic data as well as agricultural work practices followed by cases. Venous blood samples were drawn from participants and used for estimating full blood count and renal function (serum creatinine (CRE), blood-urea nitrogen (BUN), BUN : CRE ratio, and estimated GFR (eGFR)). Serum lead, arsenic, and cadmium levels were estimated using the Varian AA 240FS atomic spectrometer in an acetylene-air flame. Results. The median RBC (4.49 vs. 4.92 × 1012/L), haemoglobin (12.50 vs. 13.70 g/dL), and platelet (220.00 vs. 268.00) counts were significantly lower in cases. A significantly higher proportion of cases were classified as anaemic or having microcytic cells compared to controls. Also, serum urea (4.08 vs. 3.41; ), creatinine (108.10 vs. 101.10; ), and BUN : CRE ratio (19.75 vs. 17.84) were significantly higher in cases. Additionally, 18.1% of cases were classified as having moderately reduced renal function compared to only 6.6% of controls. Moreover, a significantly higher proportion of cases had detectable serum lead (55.6% vs. 16.4%) and arsenic (53.1% vs. 9.8%) levels compared to controls. However, on average, 80% of agricultural workers did not use personal protective equipment (PPE) when applying agrochemicals; 84.3% of used agrochemical containments were discarded near the river/canal. Conclusion. Neglect of the use of PPE may be predisposing the agrochemical workers and community to lead and arsenic bioaccumulation with a consequent reduced haematological and renal function.

  • Parathyroid Hormone Measurement in Chronic Kidney Disease: From Basics to
           Clinical Implications

    • Abstract: Accurate measurement of parathyroid hormone (PTH) is crucial for therapeutic decision-making in patients with chronic kidney disease-mineral and bone disorder (CKD-MBD). The second-generation PTH assays, often referred to as “intact PTH” assays, are the current standard and most available assays in clinical practice. However, intact PTH assays measure both full-length biologically active PTH and heterogeneous PTH fragments in the circulation, providing the equivocal value of PTH measurement in patients with CKD-MBD. Due to the variability of PTH assays, preanalytical sample errors, and the phenomenon of end-organ PTH hyporesponsiveness, current CKD-MBD guidelines recommend a wide range for serum PTH targets (2–9 the upper normal limit of the intact PTH assay) in dialysis patients to diminish the risk of developing adynamic bone disease. Nevertheless, a sizeable proportion of CKD patients still experience renal osteodystrophy despite having serum PTH levels within the recommended range. The primary cause of this inconsistency is the analytical interference of various PTH fragments and oxidized PTH forms that considerably accumulate in CKD patients. Therefore, a new mass spectrometry-based assay, which is capable of specifically measuring the whole spectra of PTH fragments, can potentially improve diagnostic accuracy for renal osteodystrophy. However, the effects of different PTH fragments on bone metabolism, vascular calcification, and mortality in CKD patients warrant further research.

  • Novel Haplotype Indicator for End-Stage Renal Disease Progression among
           Saudi Patients

    • Abstract: Background. End-stage renal disease (ESRD) is the result of hypertensive nephrosclerosis and chronic glomerular diseases and is associated with high morbidity and mortality. There are strong heritable components in the manifestation of the disease with a genetic predisposition to renal disorders, including focal segmental glomerulosclerosis and arterionephrosclerosis. Recent studies in genetics have examined modifiable risk factors that contribute to renal disease, and this has provided a deep insight into progressive kidney disease. Single-nucleotide polymorphisms at the proximity of SHROOM3, CST3, SLC7A9, and MYH9 genes have been associated with an increased risk of developing CKD and ESRD. Methods. A total of 160 CKD patients and 189 control subjects of Saudi origin participated in the study. Eight polymorphisms (SHROOM3-rs9992101, rs17319721; SLC7A9-rs4805834; MYH9-rs4821480, rs4821481, rs2032487, rs3752462; CST3-rs13038305) were genotyped using TaqMan assay, and the haplotype analysis was done using the HaploView 4.2 software. Results. Haplotype analysis revealed a novel haplotype “E6”-GTTT to be associated significantly with an increased risk for ESRD () and CKD ().Conclusion. CKD is often silent until symptomatic uremia during the advanced stages of the disease. The newly identified haplotype will help recognize patients at risk for a rapid progression of CKD to ESRD. Accurate detection and mapping of the genetic variants facilitates improved risk stratification and development of improved and targeted therapeutic management for CKD.

  • Comparison of Chronic Hemodialysis Patients under Strict Volume Control
           with respect to Cardiovascular Disease

    • Abstract: Background. The objective of this study was to determine the effects of strict volume control and nondipper situation on cardiovascular disease in chronic hemodialysis patients. Methods. This study is an observational and cross-sectional study including 62 patients with normotensive chronic hemodialysis using no antihypertensive drugs. A series of measurements including ambulatory blood pressure monitoring, left ventricular mass index by echocardiography, common carotid artery intima-media thickness by ultrasound, and body fluids by bioimpedance analysis were conducted for all subjects. Results. The patients were divided into two groups as dippers and nondippers according to their ambulatory blood pressure monitoring results.

  • Variation in Assessing Renal Allograft Rejection: A National Assessment of
           Nephrology Practice

    • Abstract: Background. The clinical utility of early detection and treatment of allograft rejection is well-established. Despite frequent testing called for by standard of care protocols, the five-year kidney allograft survival rate is estimated to be as low as 71%. Herein, we report on posttransplant care provided to kidney allograft recipients by board-certified nephrologists in the United States. Methods. We measured clinical practice in a representative sample of 175 practicing nephrologists. All providers cared for simulated patients’ status after renal transplant ranging from 30-75 years in age and 3-24 months after transplant. Our sample of nephrologists cared for a total of 525 allograft cases. Provider responses to the cases were reviewed by trained clinicians, and care was compared to evidence-based care standards and accepted standard of care protocols. Results. Among nephrologists, practicing in settings ranging from transplant centers to community practice, we found that the clinical workup of kidney injury in posttransplant patients is highly variable and frequently deviates from evidence-based care. In cases with pathologic evidence of rejection, only 29.1% (102/350) received an appropriate, evidence-based biopsy, whereas, in cases with no pathological evidence of rejection, 41.3% (45/109) received low-value, unnecessary biopsies. Conclusion. Clinical care in the posttransplant setting is highly variable. Biopsies are often ordered in cases where their results do not alter treatment. Additionally, we found that misdiagnosis was common as were opportunities for earlier biopsy and detection of rejection. This evidence suggests that better diagnostic tools may be helpful to determine which transplant patients should be biopsied and which should not. This study suggests that nephrologists and transplant patients need better tests than creatinine and proteinuria and less invasive approaches than routine biopsies to determine when transplant patients should be investigated for rejection and additional treatment.

  • Prevalence and Predictors of Chronic Kidney Disease in a Semiurban
           Community in Lagos

    • Abstract: Background and Objectives. The prevalence of noncommunicable diseases like chronic kidney disease is on the rise in third-world countries. In Nigeria and most sub-Saharan African countries, there is dearth of community-based studies on prevalence and predictors of chronic kidney disease, prompting us to undertake this study. Materials and Methods. This was a cross-sectional study, aimed at ascertaining the prevalence and predictors of chronic kidney disease (CKD) in a semiurban community in Lagos, Southwest Nigeria. The study’s subjects were recruited from Agbowa community in Ikosi-Ejirin Local Council Development Area of Lagos state. The community was randomly selected. Questionnaires were used to obtain relevant information from the subjects. Body mass index, anthropometric measurements, and other relevant data were also collected. Results. CKD was observed in 30 subjects given prevalence of 7.5% in the community. Nine out of the 30 subjects (30%) with CKD were males, while 21 (70%) subjects were females. The prevalence of CKD was significantly higher in the female population. 28 of the subjects with CKD were in stage 3, while 2 of the subjects with CKD were in stage 4. Age, hypertension, and hyperuricemia were significantly associated with CKD. Using multiple logistic regression analysis, 4 variables predicted CKD in the study population. These were age (P =0.01, OR = 0. 274, CI = 0.102 – 0.739), hypertension (p = 0.011, OR = 0. 320, CI = 0.132 – 0.773), hyperuricemia (p=0.001, OR = 0.195, CI =0.083 – 0.461), and female sex (p = 0.009, OR = 3.775, CI = 1.401 – 10.17). Conclusion. The prevalence of CKD in the population is low compared with other studies from other parts of the country, and the predictors included age, hypertension, hyperuricemia, and female gender. This is the first community-based study in Nigeria to identify hyperuricemia as a risk factor for chronic kidney disease in the country.

  • Psychosocial Mediators between Socioeconomic Status and Dietary
           Restrictions among Patients Receiving Hemodialysis in Japan

    • Abstract: The generalizability of differences in dietary restrictions (DRs) as function of socioeconomic status (SES) and the pathways of the associations between SES and DRs remain unclear. Therefore, we aimed to explore SES differences in DRs and psychosocial mediators between SES and DRs in Japanese patients receiving hemodialysis. This study was a cross-sectional survey of 6,644 outpatients (average age = 66.5 years; 65% males) of hemodialysis facilities across Japan. DRs were assessed by self-reported and objective measures, and SES was assessed based on education and income. Three psychosocial mediators were used: self-efficacy, control expectancy, and social support. Indirect influences of SES through the mediators were evaluated with a multiple mediator model. Although higher education was significantly associated with higher self-reported DRs, higher income was significantly associated with lower self-reported DRs. Significant SES differences in objective DRs were not observed. The relationships between education and self-reported DRs and objective DRs were significantly mediated by self-efficacy and/or control expectancy. The influences of income were mediated by social support. It becomes possible to design interventions targeting modifiable psychosocial factors including self-efficacy, control expectancy, and social support in order to reduce SES inequalities in DRs.

  • Urinary Uromodulin Levels and UMOD Variants in Black South Africans with
           Hypertension-Attributed Chronic Kidney Disease

    • Abstract: Uromodulin, the most abundant protein in urine, is synthesized in the thick ascending loop of Henle and distal convoluted tubules. Patients with chronic kidney disease (CKD) have reduced urinary uromodulin levels secondary to tubular damage. Genome wide association studies identified significant single nucleotide polymorphism (SNP) associations with CKD at the uromodulin (UMOD) locus. We examined the association of urinary uromodulin concentrations with CKD and with SNP rs1333226 in the UMOD gene. The study included 71 black South Africans with hypertension-attributed CKD with an eGFR ≤ 60ml/min/1.73m2, 52 first-degree relatives, and 58 unrelated controls. Urinary uromodulin concentration was measured using Luminex® multiplex kits. After DNA extraction from blood using the Maxwell® automated platform, genotyping of rs13333226 was performed using real-time PCR using TaqMan® genotyping assays. Urinary uromodulin levels were significantly lower in CKD cases compared to both controls and first-degree relatives and correlated negatively with age, serum uric acid, serum creatinine, and systolic BP and positively with CKD-EPI eGFR. For each 1-standard deviation increase in uromodulin level, the multivariable-adjusted odds ratio for CKD was 0.6 (95% CI [0.48 to 0.81]; p

  • Regulation of (Pro)Renin Receptor in Renin-Positive Smooth Muscle Cells of
           Kidney Arterioles in Rats with STZ-Induced Diabetes

    • Abstract: Objective. The nephron (pro)renin receptor may play a pathophysiological role in renal disorders in hypertension or diabetes. The aim of this study was to determine the relationship of (pro)renin receptors and transdifferentiation between the renin-negative and renin-positive SMCs in the afferent arteriole by estimating the distribution of (pro)renin receptors in renin-positive and renin-negative SMCs of the afferent arteriole of kidneys in normal and streptozotocin- (STZ-) induced diabetic rats. Therefore in diabetes the renin granulation of afferent arterioles is different as in normal, the diabetes model for finding the differences to normal in distribution of (pro)renin receptors of afferent arterioles was used. Method. To estimate the number of (pro)renin receptors in arteriolar SMCs a special protocol of immunohistochemistry to stereology was followed. Results. Our results showed that on the surface of renin-positive SMCs the number of (pro)renin receptors was upregulated, while in the cytoplasm of SMCs there was downregulation in comparison to renin-negative SMCs. There is a significant difference between the number of (pro)renin receptors on the surface and in the cytoplasm of renin-positive SMCs in normal rats. These differences in the number of (pro)renin receptors were not present in rats with STZ-induced diabetes. Any other differences in the number of (pro)renin receptors between the STZ-induced diabetic and normal rats were not detected. The tissue level of angiotensin II did not change in the kidneys of STZ-induced diabetic rats. Conclusion. The distribution of (pro)renin receptors in afferent arteriolar SMCs is related to renin granulation of SMCs, but independent of angiotensin II plasma or tissue levels in the kidney.

  • Kidney Injury Molecule 1 (KIM-1) as an Early Predictor for Acute Kidney
           Injury in Post-Cardiopulmonary Bypass (CPB) in Open Heart Surgery Patients

    • Abstract: Introduction. Postoperative acute kidney injury is associated with a higher mortality, a more complicated hospital course with longer hospital stay. Urinary kidney injury molecule 1 may play an important role as an early predictor of acute kidney injury post-cardiopulmonary in open heart surgery. Methods. We evaluated 45 patients who underwent open heart surgery from January 2016 to June 2016. Both urinary kidney injury molecule 1 and serum creatinine were evaluated before operation and 3hs and 24hs after operation. Acute kidney injury was diagnosed according to Kidney Disease: Improving Global Outcomes, 2012 guidelines. Results. In this study, 27 patients developed acute kidney injury. The three hour-post-surgery urinary kidney injury molecule 1 was significantly higher in the acute kidney injury group (P

  • Reduced Kidney Function in Tenofovir Disoproxil Fumarate Based Regimen and
           Associated Factors: A Hospital Based Prospective Observational Study in
           Ethiopian Patients

    • Abstract: Purpose. Tenofovir disoproxil fumarate (TDF), a drug broadly used in combination antiretroviral therapy, is associated with renal dysfunction but the prevalence varied from country to country and it is not known in Ethiopia. The objectives of this study were to assess the prevalence of renal dysfunction and risk factors associated with it and the mean change in estimated glomerular filtration rate in human immunodeficiency virus infected patients receiving TDF based antiretroviral regimen at Tikur Anbessa Specialized Hospital. Method. It was a hospital based prospective cohort study. The study participants were treatment naïve HIV infected patients initiating TDF containing combination antiretroviral therapy or switched to it because of adverse events. Multivariable logistic analysis was used to identify variables which have significant association. Result. A total of 63 study participants were studied, 16 (25.4%) of whom had fall in eGFR greater than 25% relative to baseline. Only age greater than 50 years, baseline CD4 count less than 200 cells/mm3, and baseline proteinuria were significantly associated with renal dysfunction in multivariable logistic regression. There was -8.4 ml/min/1.73m2 mean change in estimated glomerular filtration rate relative to baseline at six months of study. Conclusion. The renal dysfunction (defined as decline in eGFR greater than 25%) was found in a quarter of the study population. The long term impact and the clinical implication of it are not clear. Future prospective study is required with large sample size and long duration to ascertain the prevalence of decline greater than 25% in estimated glomerular filtration rate and its progression to chronic kidney disease.

  • Renal Recovery following Liposomal Amphotericin B-Induced Nephrotoxicity

    • Abstract: Background. Acute kidney injury (AKI) is a common complication of treatment with liposomal amphotericin B (LAmB). The trajectory of renal recovery after LAmB-associated AKI has not been well described, nor has effect of LAmB dose on recovery of renal function been explored. Objective. Characterize the pattern of renal recovery after incident AKI during LAmB and determine potential influencing factors. Methods. This retrospective cohort study analyzed patients who developed a ≥50% increase in serum creatinine while on LAmB. Patients were followed up until complete renal recovery or death or for 30 days, whichever occurred first. The primary outcome was complete renal recovery, defined as serum creatinine convalescence to within 10% of the patient’s pretreatment baseline. Multivariable modeling was used to identify independent predictors of renal recovery. Results. Ninety-eight patients experienced nephrotoxicity during LAmB, 94% of which received doses

  • Functional and Respiratory Capacity of Patients with Chronic Kidney
           Disease Undergoing Cycle Ergometer Training during Hemodialysis Sessions:
           A Randomized Clinical Trial

    • Abstract: Purpose. Exercise is recommended for patients undergoing hemodialysis, to reduce the decrease in functional capacity secondary to the progression of chronic kidney disease. A cycle ergometer can be easily added to an exercise routine during hemodialysis sessions. The purpose of this article was to assess the results of a training protocol with the cycle ergometer during hemodialysis sessions on the respiratory function and functional capacity of patients with chronic kidney disease on hemodialysis. Method. In this randomized clinical trial (NCT no. 02834026), 39 patients undergoing hemodialysis were randomly allocated into two groups: the treatment group (TG, n = 20), who underwent a cycle ergometer protocol training, and the control group (GC, n = 19), not trained. The TG attended 24 training sessions, three times a week, during the intradialytic period. Training intensity was aimed at keeping the heart rate between 50 and 70% of its maximum. All participants were evaluated before and after the eight consecutive weeks of follow-up and had biochemicals data, anthropometric, functional, and respiratory outcomes evaluated. Results. A significant difference was observed between groups in forced vital capacity, forced expiratory volume in the first second, peak expiratory flow, maximal inspiratory and expiratory pressure, and Borg score and distance covered in the six-minute walk test. Improvement was also observed in biochemical and Kt/V test results for the TG. Conclusion. The systematic training regimen with a cycle ergometer resulted in benefits in the respiratory function and functional capacity in patients with chronic kidney disease undergoing hemodialysis.
