AbstractAbdominal aortic aneurysms (AAA) primarily affect elderly men who often have many other diseases, with similar risk factors and pathobiological mechanisms to AAA. The aim of this study was to assess the prevalence of simple renal cysts (SRC), chronic kidney disease (CKD), and other kidney diseases (e.g. nephrolithiasis) among patients presenting with AAA. Two groups of patients (100/group), with and without AAA, from the Surgical Clinic Charité, Berlin, Germany, were selected for the study. The control group consisted of patients who were evaluated for a kidney donation (n = 14) and patients who were evaluated for an early detection of a melanoma recurrence (n = 86). The AAA and control groups were matched for age and sex. Medical records were analyzed and computed tomography scans were reviewed for the presence of SRC and nephrolithiasis. SRC (73% vs. 57%; p<0.001) and CKD (31% vs. 8%; p<0.001) were both more common among AAA than control group patients. On multivariate analysis, CKD, but not SRC, showed a strong association with AAA. Knowledge about pathobiological mechanisms and association between CKD and AAA could provide better diagnostic and therapeutic approaches for these patients.

Abstract Background and Aims Chronic kidney disease (CKD) is a major public health problem worldwide and refers to a wide range of disorders in bone and mineral metabolism, abnormalities of biochemical parameters and pathological calcification of the blood vessels. Vascular calcification (VC) is a common complication in CKD patients, contributes to cardiovascular disease (CVD), and associates with increased mortality and morbidity. The precise mechanism of VC in CKD is not yet fully understood. Recently discovered molecules such as osteoprotegerin (OPG), its ligand receptor activator of nuclear factor NF-κB ligand (RANKL) and RANK are not only well-known to play a crucial role in bone homeostasis, but they has also been implicated in the process of development of vascular complications However the exact role of OPG/RANKL/RANK axis in the process of VC has not been yet fully assessed. Thus, the aim of this work is to evaluate the role of OPG/RANKL/RANK axis in the process of calcification in CKD. Method Seventy two male Wistar rats weighing 260-290 g (8-weeks old) were initially divided into 6 groups containing 12 animals in each group. Rats were divided into six groups: control rats (K4, K6, K8) and CKD rats (B4, B6, B8). Control group rats received standard diet, whereas CKD rats were fed a low adenine – diet containing 0.3 % adenine, 1.0 % Ca, 1.2 % Pi through 4 (K4, B4), 6 (K6, B6) and 8 (K8, B8) weeks. Subsequently, CKD and control rats were sacrificed at weeks 4 (n=24), 6 (n=24) and 8 (n=24). One day before being killed, the rats were placed in metabolic cages for 24-hour urine collection. Thereafter, the rats were anesthetized and samples of blood, as well as aortas were collected. Next, the OPG, RANKL, parathyroid hormone (PTH), 25-hydroxyvitamin D (25(OH)D) and 1,25-dihydroxy vitamin D3 1,25(OH)2D3 concentrations were determined using appropriate ELISA kits. Then the sRANKL/OPG ratio was calculated. The OPG, RANK and RANKL gene expression was assessed using real-time PCR (RT-PCR). The VC was quantified by measurement of the arterial calcium (Ca) and phosphate (Pi) content using flame atomic absorption. Serum levels of urea nitrogen, creatinine, uric acid, Ca, Pi and urinary levels of creatinine, Ca and Pi were measured. Results There was a progressive increase in serum urea nitrogen, creatinine, uric acid and PTH of CKD rats in comparison to control values. We also observed significantly decreased levels of 25(OH)D, 1,25(OH)2D and serum Ca. Total Ca content in the aorta was significantly increased in CKD rats in comparison with control group, whereas total Pi content in the aorta was significantly increased only in B8 group in comparison to appropriate controls. There were no differences in serum OPG and sRANKL levels between CKD and control rats. In contrast, we observed decreased OPG, RANKL and RANK gene expression in a B4 group in comparison to appropriate controls, whereas in a B6 group we noticed increased OPG, RANKL and decreased RANK gene expression. B8 group revealed increased RANKL and RANK gene expression, but there were no differences in OPG gene expression between CKD rats and control group. Furthermore, we observed positive correlations between serum sRANKL and OPG and RANK gene expression. Ca and P content in the aorta inversely corelated with RANKL gene expression, whereas positively with OPG gene expression. Serum 25(OH)D concentrations correlated inversely with Ca in aorta. PTH was positively correlated with serum RANKL and OPG and gene expression these cytokines. Conclusion Our results suggest that OPG/RANK/RANKL axis may be involved in the process of vascular calcification in chronic kidney disease. However, its role and evaluation of precise mechanism in this field requires further evaluation.

 Background: Chronic kidney disease (CKD) includes irreversible destruction of nephrons leading to progressive decline in glomerular filtration rate. A preferential defect in Homocysteine disposal could hypothetically occur in CKD and subsequently lead to hyperhomocysteinemia. Understanding the status of Homocysteine and other parameters in CKD is useful in the management of the disease. Objective of the study is to estimate serum Homocysteine in CKD patients and its association with renal function and serum albumin in patients with CKD.Methods: The study design involves hospital based observational comparative study. The study was conducted in Department of Biochemistry in association with Department of Nephrology of Mahatma Gandhi Medical College and Hospital, Jaipur between May 2017 to June 2018. 100 diagnosed patients of CKD, visiting the Outpatient Department of Nephrology were enrolled as cases for the study. Patients having cardiovascular disease, Chronic liver disease, Age more than 60 years and pregnant females were excluded from study. The control group consists of 100 age and sex matched healthy individuals.Results: The mean serum creatinine levels of case and control group were 7.50±3.74 mg% and 0.83±0.22 mg% respectively. The mean of serum homocysteine levels of subject group was 27.35±12.52 µmol/L while the mean serum homocysteine levels of control group was 11.06±3.52 µmol/L. The serum homocysteine levels were significantly higher in the CKD patient group. The serum level of albumin in CKD patients and control group were 2.86±0.86 g/dl and 4.10±0.58 g/dl respectively. A positive correlation was found between serum creatinine and serum homocysteine levels. A negative correlation between serum homocysteine and serum albumin was found.Conclusions: Findings of the present study exhibit that serum homocysteine levels are elevated in CKD in comparison to healthy controls and it is positively correlated with serum creatinine level.

Introduction: Chronic Kidney Disease (CKD) is a pathological condition that occurs gradually and is irreversible, characterized by structural and functional abnormalities in the kidneys that lasts for more than three months. The C allele in the Neuropeptide Y (NPY) RS16147 gene is closely related to an increase in the incidence of hypertension, a decrease in glomerular filtration rate, and an increase in total cholesterol levels in CKD patients. Objective: To determine the effect of the NPY RS16147 gene polymorphism on the blood pressure of chronic kidney disease patients and control healthy in Medan Indonesia. Methods: This study is an analytical study with a case-control design at the Haji Adam Malik General Hospital Medan from July to August 2020. All subjects had Deoxyribonucleic Acid (DNA) analysis using Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP) method. Results: We obtained 100 study subjects, 43 was CKD patients with dialysis, 31 CKD patients without dialysis, and 26 control healthy groups. In this study, there were differences in the trend genotypes of NPY RS16147 polymorphism with the incidence of CKD and control healthy. We obtained a significant difference the mean systolic blood pressure patients with genotypes TT (139,05±21,42) and TC/CC (151,32±22,26) as evidenced by the value of P = 0.00 (≤0.05). The presence of the "C" allele in the NPY RS16147 gene sample increased blood pressure in all study subjects significantly (P=0.028; ≤0.05). Conclusion: the "C" allele in the NPY RS16147 gene affects systolic blood pressure. Keywords: NPY RS16147 polymorphism, Chronic kidney disease, Blood pressure.

This was a hospital based prospective, interventional study which included CKD stage 3- 5 patients with higher level of uric acid (male>7mg/dl, female>6mg/dl). The objective of the study was to evaluate the effect of allopurinol in chronic kidney disease (stage 3-5) progression in asymptomatic hyperuricaemic patients.One hundred and twenty patients were distributed in two groups. Sixty patients were placed in treatment group and sixty in control group. Purposive sampling technique was followed. In the study mean age was 49 (±9) years in treatment group and 45 (±11) years in control groups. Male were predominant in both groups. There were no significant difference in baseline characteristics between treatment group and control group (p>0.05). Sixty patients of treatment group were administered a dose of 100 mg/d of allopurinol. Follow up assessment was done at basally, at 4 months and at 8 month after starting treatment. No significant differences were seen between baseline SBP, DBP, Hb and HbA1c with 4th month and 8th month follow up in both treatment group and control group, but mean Hb was significantly decreased in control group from the baseline after 8 month. Serum uric acid was decreased in treatment group while it was significantly raised from the base line at 4th month and 8th month in control group. In treatment group serum creatinine was decreased and eGFR was raised from the baseline after 8 month. On the other hand, in control group serum creatinine was significantly raised and eGFR was significantly decreased from the baseline at 8th month. While comparing between two groups results showed means of serum uric acid was significantly decreased in treatment group compared to control group after 8th month. There was a negative correlation between Uric Acid with eGFR after 8 month of allopurinol treatment although this finding was not statistically significant. So, allopurinol may have a protective role in CKD progression by decreasing serum uric acid level in patients with chronic kidney disease stage 3 - 5 with asymptomatic hyperuricaemia.J Dhaka Medical College, Vol. 25, No.1, April, 2016, Page 5-15

Background: Patients with Chronic Kidney Disease (CKD) are at significantly increased risk for both morbidity and mortality from cardiovascular disease (CVD). Determining the spectrum of echocardiographic abnormalities in these patients can help in reduction of morbidity and mortality from CKD. Materials and Methods: This cross-sectional study was held on department of Pediatric Nephrology, Dhaka Shishu Hospital, Dhaka, during July 2018 to December 2018 (Six months). A total of thirty-six children with chronic kidney disease with creatinine clearance <60ml/min/1.73 m2 and age ranged from 2 to 16 years on supportive treatment and hemodialysis were included. In control group equal number of age and sex matched healthy children without any preexisting renal or cardiovascular diseases were included. Both study group and control group were assessed for cardiovascular findings by echocardiography. Results: The mean age was 9.09±3.01 years (mean±SD) in case group and 7.85±3.69 years (mean±SD) in control group. Regarding sex, 22 patients (61.1%) in the case group were male and 14 (38.9%) were female.  In this study, in CKD patients significant (p<0.001) difference was observed in following cardiac parameters, left ventricular end diastolic diameter (LVEDD) (38.34 vs 34.52), left ventricular end systolic diameter LVESD (26.64 vs 20.75), interventricular septal thickness (IVS) (9.34 vs 7.27), left ventricular posterior wall thickness (LVPWT) (8.36 vs 7.46), ejection fraction (EF) (56.68% vs 70.36%), fractional shortening (FS) (31.88% vs 38.30%) and peak early diastole velocity/peak atrial filling velocity (E/A ratio) (1.15 vs 1.45) when compared to control group. Most common cardiac abnormality in children with chronic kidney disease were left ventricular systolic dysfunction (44.4%), mild pulmonary hypertension (30.6%) and left atrial dilatation (27. 8%). Conclusion: Left ventricular systolic dysfunction was the commonest echocardiographic findings in CKD children. There was also significant difference in diastolic function between study and control group.
