Background:Chronic kidney disease-mineral and bone disorder (CKD-MBD) is complex and management can be difficult. We aimed to compare management of our CKD patients to 2018 KDIGO guidelines. The guidelines suggest checking calcium and phosphate (Ca/PO4) within 12 mths in CKD 3a and 3b, within 6 mths for CKD 4, and within 3 mths for CKD 5. Parathyroid hormone (PTH) should be checked at baseline in CKD 3a-b, within 12 mths in CKD 4 and within 6mths in CKD 5. Alkaline phosphatase (ALP) should be measured within 12 mths in CKD 4 and 5. 25-(OH)D levels ‘might’ be measured at baseline in CKD 3a to 5D. BMD scanning is suggested if the result will impact treatment decisions. Lateral abdominal X ray is recommended as an alternative to CT for detection of vascular calcification. Calcitriol and vitamin D analogues are no longer routinely advised in CKD 3a-5; 25-(OH)D insufficiency should be corrected as in the normal population.Objectives:To compare management of our CKD patients to 2018 KDIGO guidelinesMethods:We randomly selected 70 patients in whom data was available from renal clinics between May and September 2019.Results:Mean age was 67.3 yrs. 41 male, 29 female. 33 patients had CKD 3a-b; 31 had CKD 4; 6 had CKD 5. Mean duration of CKD was 10.6 yrs. 10 patients were taking activated vitamin D analogues; 13 were taking 25-(OH)D analogues. 25-(OH)D levels ranged from 24-158 nmol/L (mean 65nmol/L). PTH levels ranged from 2- 69pmol/L (mean 23pmol/L). 3 patients were taking bisphosphonates. 44 had previous lumbar spinal imaging; vertebral fractures were evident in 4 (9%). 12 patients had had DXA scans; lowest T score was -2.5.

Nevertheless, our results suggest that bone biochemistry could be checked more consistently in CKD patients. Although detection of vascular calcification may not alter renal management, abdominal imaging provides an opportunity to screen for vertebral fracture, present in a significant number of our patients. The KDIGO guidelines offer a framework to work with our renal colleagues, as many patients will be jointly managed.References:[1]Diagnosis, Evaluation, Prevention, and Treatment of Chronic Kidney[2]Disease–Mineral and Bone Disorder: Synopsis of the Kidney Disease:[3]Improving Global Outcomes 2017 Clinical Practice Guideline Update.

Patients with chronic kidney disease (CKD) develop mineral and bone disorder (MBD), a common and important complication, as a result of impaired phosphorus excretion and reduced vitamin D activation. Altered mineral metabolism is now recognized as an independent cardiovascular risk factor in end-stage renal disease patients and contributes to the risk for accelerating vascular calcification. CKD patients are at high risk for cardiovascular disease and vascular calcification which account for the high morbidity and mortality in this patient population. Pharmacotherapeutic interventions are necessary to manage and treat the condition. Multiple classes of agents including phosphorus binders, vitamin D analogs, and calcimimetics are now available to treat CKD-MBD. Recent data have shown that treatment with sevelamer and vitamin D analogs are associated with a reduction in calcification and cardiovascular mortality and improved survival. This article provides an overview of the strategies and considerations for the management of CKD-MBD, as well as their implications on clinical outcomes.

Abstract Background and Aims The mineral bone disorder is an essential problem in chronic kidney disease (CKD). It is an independent modifiable risk factor for renal damage progression and CKD related mortality. Therefore, it is important to treat chronic kidney disease mineral bone disorder (CKD-MBD) according to international guidelines. Data on the management of mineral bone disorders in predialysis patients is scarce. We aimed to investigate the proportion of CKD-MBD patients reaching targets suggested by the updated 2017 KDIGO guidelines. Method We performed a multicenter cross-sectional study. We recruited consecutive adult (>18 years of age) CKD 3-5 patients who were on regular nephrology outpatient clinic follow up. Patients who have GFR loss over 30% in the last six months, patients with malignancy, and decreased life expectancy due to severe comorbid disease and patients on renal replacement therapy were excluded. Data were collected in two-time points: one during the recruitment (second data point) and one, three to six months prior to the current visit (first data point). Persistent laboratory abnormalities were defined by out of normal range values in both time points. Therapeutic inertia was calculated for hyperphosphatemia. It was defined as a lack of using phosphate binders despite hyperphosphatemia. Results We examined a total of 213 patients for 3 different nephrology outpatient clinics. Of these patients, 49.5 % were male, with a mean age of 64,9 ± 12,0 years. 51.7 % of the patients were diabetic, 78 % were hypertensive, and 20.1 % had a history of coronary artery disease. Laboratory values related to MBD are shown in Table 1. KDIGO guideline targets were not reached in 14.8%, 18.4%, 59.0%, 71.0% patients regarding Ca, P, PTH, and vitamin D in the first visit. The targets were not reached in 15.0%, 19,2%, 61,2%, 81% patients regarding Ca, P, PTH, and vitamin D in the second visit. Persistence of out of target values were observed in 5.8%, 9.9%, 49.2% and 65.4% of the patients for Ca,P, PTH and Vitamin D respectively. The prevalence of therapeutic inertia for hyperphosphatemia was 34,4 % in the second visit Conclusion Regarding KDIGO guidelines, MBD is not optimally managed in predialysis CKD patients. Clinicians should have an active attitude regarding the correction of MBD even at the earlier stages of CKD.

Calcium Phosphorus

Chronic kidney disease is associated with the inability to control normal mineral homeostasis, resulting in abnormalities in serum levels of calcium, phosphorus, parathyroid hormone, fibroblast growth factor 23 (FGF23) and vitamin D metabolism. These disturbances lead to the development of secondary hyperparathyroidism, skeletal abnormalities, vascular calcifications, and other systemic manifestations. Traditionally, mineral and bone abnormalities seen in chronic kidney disease were included in the term ‘renal osteodystrophy’. More recently, the term chronic kidney disease-mineral and bone disorder was introduced to define the biochemical abnormalities of phosphorus, parathyroid hormone, FGF23, calcium, or vitamin D metabolism, abnormalities in bone remodelling and mineralization, and vascular or other soft tissue calcifications.

ZusammenfassungDer sekundäre Hyperparathyreoidismus führt zu renaler Osteodystrophie („chronic kidney disease-mineral and bone disorder” [CKDMBD]) und progredienten Gefäßverkalkungen. Indikationen für eine Parathyreoidektomie (PTX) umfassen ein Versagen der medikamentösen Therapie bestehend aus Phosphatbindern, aktivem Vitamin D und Kalzimimetika sowie eine knochenbioptisch nachgewiesene hyperparathyreoide Knochenerkrankung, sonografisch vergrößerte Epithelkörperchen, pathologische Frakturen, therapierefraktärer Juckreiz und/oder eine Kalziphylaxie. Die PTX kann als subtotale oder totale PTX mit und ohne Thymektomie und mit und ohne Autotransplantation von Nebenschilddrüsengewebe erfolgen. Wir favorisieren die totale Parathyreoidektomie ohne Autotransplantation und ohne Thymektomie. Dieses ist ein sicheres, rezidivarmes und kosteneffektives Verfahren, postoperativ einfach substituierbar und ermöglicht die adäquate Dosierung von aktivem Vitamin D.

ABSTRACT Introduction: The diagnosis and treatment of mineral and bone disorder of chronic kidney disease (CKD-MBD) is a challenge for nephrologists and health managers. The aim of this study was to evaluate the prevalence, biochemical profile, and drugs associated with CKD-MBD. Methods: Cross-sectional study between July and November 2013, with 1134 patients on dialysis. Sociodemographic, clinical, and laboratory data were compared between groups based on levels of intact parathyroid hormone (iPTH) (< 150, 150-300, 301-600, 601-1000, and > 1001 pg/mL). Results: The mean age was 57.3 ± 14.4 years. The prevalence of iPTH < 150 pg/mL was 23.4% and iPTH > 601 pg/mL was 27.1%. The comparison between the groups showed that the level of iPTH decreased with increasing age. Diabetic patients had a higher prevalence of iPTH < 150 pg/mL (27.6%). Hyperphosphatemia (> 5.5 mg/dL) was observed in 35.8%. Calcium carbonate was used by 50.5%, sevelamer by 14.7%, 40% of patients had used some form of vitamin D and 3.5% used cinacalcet. Linear regression analysis showed a significant negative association between iPTH, age, and diabetes mellitus and a significant positive association between iPTH and dialysis time. Conclusion: The prevalence of patients outside the target for iPTH was 50.5%. There was a high prevalence of hyperphosphatemia (35.8%), and the minority of patients were using active vitamin D, vitamin D analogs, selective vitamin D receptor activators, and cinacalcet. These data indicate the need for better compliance with clinical guidelines and public policies on the supply of drugs associated with CKD-MBD.
