Mdrd Formula

Introduction: The diagnosis and classification of chronic kidney disease (CKD) are based on the glomerular filtration rate value. The simplest way to evaluate glomerular filtration rate is to estimate it based on serum creatinine concentration using one of many specific mathematical formulas. None of the formulas created for this purpose are perfect. Differences in eGFR values are frequently observed in specific stages of chronic kidney disease by KDIGO classification based on different formulas. Aim: The aim of the study is to compare the eGFR value in patients previously diagnosed with CKD treated in the Outpatient Nephrology Unit of the University Hospital in Krakow using the selected formulas. Material/Methods: The study was performed in a group of 882 patients (392 women, 490 men) aged 65.0 ± 14.8 years. GFR values were estimated using Bjornsson, the abbreviated MDRD, and CKD-EPI formulas. These values were then compared according to chronic kidney disease stage and age groups: above and below 60 years. Results: The mean eGFR value was for Bjornsson formula- 47.2 ± 21.1 ml/min/1.73m2, abbreviated MDRD formula- 38.8 ± 15.2 ml/min/1.73m2, and CKD-EPI formula- 37.7 ± 15.9 ml/min/1.73m2. There was a large concordance in eGFR values obtained using the CKD-EPI and abbreviated MDRD formulas in every stage of chronic kidney disease and in both age groups. The Bjornsson formula significantly increased the number of patients in early stages of CKD, G1 - 33 vs 2 (abbreviated MDRD) and 6 (CKD-EPI), G2- 186 vs 70 (abbreviated MDRD) and 69 (CKD-EPI). Conclusions: CKD-EPI and abbreviated MDRD formulas have a similar usefulness in GFR value estimation in patients with diagnosed chronic kidney disease. Lower eGFR values achieved using abbreviated MDRD formula and CKD-EPI equation in comparison with Bjornsson’s formula may result in an increased number of patients diagnosed with CKD.

Introduction: The degree of glomerular filtration rate determines the stages of chronic renal disease and, therefore, knowledge on its estimation is essential. Aims: Two standardized creatinine based estimated glomerular filtration rate equations and five equations based on the immunoturbidimetric determination of cystatin C were compared. Methods: The distribution of the analytes and the equations, their relations, as well as the differences among the estimated glomerular filtration rates and their chronic kidney disease stages assignments were studied. Results: The equations based on cystatin C classified more patient into stage 1, while the creatinine based ones more into stages 2, 3 and 4. The equations published as Grubb1, Grubb2 and Larsson classified more patients while the equations created by Tan and Sjöström classified fewer into stage 5 compared to the creatinine based equations. The equations of Grubb1 and Grubb2 resulted in the most similar stage assignment. The occurence of stages between 3 and 5 was the lowest using the equation of Sjöström. Conclusions: The different equations for the estimation of glomerular filtration rate modify significantly the chronic kidney disease stage assignment which may have an influence on the treatment and outcome measures of the patients.

Introduction: Chronic Kidney Disease (CKD) is a progressive loss in renal function over period of many months or years. As compared to the past decades, the number of kidney diseases leading to end CKD is increasing in Nepal. The disease is associated with the decreased glomerular filtration rate (GFR). There is decline in nephron function and number generally quantitated as reduction in glomerular filtration rate. As the GFR declines, there is accumulation of metabolic end products excreted by Kidney. Chronic kidney disease is identified by blood tests, creatinine and urea are two such substances routinely measured. Serum amylase is a pancreatic digestive enzyme that normally acts extracellular to cleave starch into smaller carbohydrate groups and, finally, into monosaccharide's. It is produced by 40-45% from the pancreas and (45%) reabsorbed by tubular cells. Elevations in serum total amylase among patients with CKD is due to impaired renal clearance and seen mostly when the creatinine clearance is below 50 ml/min. Several studies have been reported on this but there are no studies that have been done so far in Nepalese context.Objectives: This study is designed to correlate serum amylase with CKD stage three to stage five in patients of chronic renal disease irrespective of hemodialysis and prevalence of risk factors of CKD and different factors that may affect the level of serum amylase in patients presenting to Bir Hospital Nephrology department, Nepal.Methods: The study was a cross-sectional, observational, descriptive, hospital based carried out in Nephrology Unit of Bir hospital both inpatient or outpatient irrespective of hemodialysis from March 2014 to March 2015. Patients with increased serum amylase due to acute Pancreatitis, Mumps, Intestinal Obstruction, Peptic Ulcer, Cancer, other than renal cause were excluded. The results were analyzed using SPSS version 11 and Microsoft Excel by correlation coefficient. Result: Present study shows that among 126 patients, the prevalence of age group was from 15 years to 78 years with majority being male. The serum amylase levels were significantly higher in Chronic Kidney Disease Stage V with significant p-value. At 80-100 Serum Amylase level had strong correlation of 0.504 for CKD III stage and significant at 10 percent level. The correlation between CKD IV at 80-100 was significant at 10 percent but weak of 0.189. Whereas, CKD V was highly significant but negative at more than 161 Serum Amylase.Conclusion: From the study it was concluded that in Chronic Kidney Disease, Serum amylase was found to be higher as the eGFR decreases. BJHS 2018;3(2)6:403-407.

Introduction: Chronic Kidney Disease is a worldwide public health problem that affects millions of people from all racial and ethnic groups. Identification of a Chronic Kidney Disease is a major risk factor for cardiovascular morbidity and mortality and is attributed to hyperuricemia. Evidences show that high serum uric acid contribute directly to glomerulosclerosis, interstitial fibrosis and atherosclerosis that correction of hyperuricemia associated with Chronic Kidney Disease will slow the progression of chronic renal failure.  Methods: A hospital based cross-sectional study on chronic kidney disease patients including 57 patients on conservative treatment attending Bir Hospital with diagnosis of chronic kidney disease was performed. Detailed clinical history, examination and investigations including uric acid were done. Chronic Kidney Disease staging was done according to estimated glomerular filtration rate estimated by Cockcroft-Gault equation. Prevalence rate of hyperuricemia in Chronic Kidney Disease and its stages were calculated and compared with each other. Results: A total of 57 Chronic Kidney Disease cases were enrolled, with male to female ratio of 2:1 and mean age 51.63±17.75 years. Hyperuricemia was present in 55 (96.49%) of study population. Though prevalence of hyperuricemia increased with Chronic Kidney Disease stage, there was no significant difference in mean value of uric acid in different stages. Hyperuricemia and stages of Chronic Kidney Disease had negative correlation which was statistically significant. Conclusions: Hyperuricemia is highly prevalent among Chronic Kidney Disease patients with conservative management. The severity of hyperuricemia increases as Chronic Kidney Disease stage progresses.

BackgroundKidney disease, especially chronic kidney disease (CKD), is common in older dogs. The biomarkers symmetric dimethylarginine (SDMA) and creatinine (Cr) are indicators of glomerular filtration rate (GFR). This retrospective study used these biomarkers to identify groups at risk of decreased GFR at the breed level.MethodsData from dogs with a single serum chemistry result that included Cr and SDMA submitted between July 2015 through December 2017 were included. Dogs were identified by breed and age group. Decreased GFR was defined as Cr above 1.9 mg/dl or SDMA above 18 µg/dl.ResultsFourteen breeds had a significantly higher percentage of dogs with increased SDMA or Cr for one or more age groups. Geriatric and senior Shetland sheepdogs, Yorkshire terriers and Pomeranians were significantly more likely to have increased renal biomarkers. Boxers were identified with significantly increased renal biomarkers in the age groups spanning two months to 10 years of age.ConclusionEvidence of decreased GFR occurred commonly in older dogs of most breeds, especially geriatric dogs greater than 10 years of age, but there were some exceptions, with more significant changes affecting younger animals of several breeds. The combination of SDMA and Cr identified more cases of decreased GFR than either SDMA or Cr alone.

Introduction: Chronic kidney disease (CKD) is an international public health problem affecting about 5–10% of the population. It is the ninth leading cause of death. A trend towards increased incidence and prevalence is being reported worldwide with epidemic proportions in many countries. CKD is associated with variety of endocrine disturbances among which thyroid dysfunction is most common. This is probably due to reduce circulating hormone levels, altered binding of hormone to carrier protein or due to reduced peripheral metabolism of hormone. Materials and Methods: The study included 100 patients diagnosed with CKD. Both male and female patients aged between 30-70 years were selected for the study. Estimated Glomerular Filtration Rate (eGFR) was calculated using Modification of Diet in Renal Disease (MDRD) formula. Total T3, Total T4, TSH levels were measured by CLIA methodology. Results: Statistically significant alteration in TSH (p<0.01) values were seen with eGFR suggesting that alteration in the eGFR may lead to thyroid hormone resistance.

BACKGROUND. The lack of data on the epidemiology of presarcopenia/sarcopenia leads to an underestimation of the role of this condition in the structure of morbidity and mortality of haemodialysis patients in theRussian Federation. THE AIM: to study the epidemiological aspects of presarcopenia /sarcopenia in patients with chronic kidney disease stage 5d. PATIENTS AND METHODS. This study comprised 317 patients receiving programmed bicarbonate haemodialysis for 8.2 ± 5.1 years, among them 171 women and 146 men, the average age was 57.1 ± 11.3 years. The assessment of the presence of sarcopenia was performed using the method recommended by the European Working Group on Sarcopenia in Older People. RESULTS. The prevalence of presarcopenia was 0.7 % and sarcopenia 29.6 %. The incidence of skeletal muscle mass deficiency according to muscle mass index (IMM) was 30.3 %, 48.7 % showed a decrease in muscle strength according to dynamometry, and low performance of skeletal muscles according to 6 minute walk test was determined in 42.8 %. Sarcopenia patients were significantly characterized by lower body mass index, as well as higher body fat mass values. The duration of haemodialysis (χ2 = 22.376, p = 0.0001) and the patient's age (χ2 = 10.545 p = 0.014) were an independent risk factors for the development of sarcopenia. CONCLUSION. Sarcopenia is recorded more frequently in hemodialysis patients than presarcopenia. Its prevalence increases among patients of older age groups and with a hemodialysis duration of more than 5 years. The age and experience of dialysis make their independent contribution to the development of this syndrome.
