Native hypovitaminosis D (n-hVITD) is frequently found from the early stages of chronic kidney disease (CKD) and its prevalence increases with CKD progression. Even if the implications of n-hVITD in chronic kidney disease-mineral bone disorder (CKD-MBD) have been extensively characterized in the literature, there is a lot of debate nowadays about the so called “unconventional effects” of native vitamin D (25(OH)VitD) supplementation in CKD patients. In this review, highlights of the dimension of the problem of n-hVITD in CKD stages 2–5 ND patients will be presented. In addition, it will focus on the “unconventional effects” of 25(OH)VitD supplementation, the clinical impact of n-hVITD and the most significant interventional studies regarding 25(OH)VitD supplementation in CKD stages 2–5 ND.

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.

ZUSAMMENFASSUNGDer Begriff CKD-MBD (Chronic Kidney Disease – Mineral Bone Disorder) ist seit einigen Jahren für Störungen des Kalzium-Phosphat-Stoffwechsels und der damit verbundenen Risiken für das Mineral-Knochen- und Herz-Kreislauf-System bei chronischen Nierenerkrankungen bekannt. Die Bezeichnung entstand nach einem Paradigmenwechsel in der Pathophysiologie des sekundären Hyperparathyreoidismus und da neue Akteure wie FGF23 und Klotho gefunden wurden, die eine wichtige Rolle bei der Entstehung der Störungen spielen. Das wachsende Verständnis der Zusammenhänge zwischen den neuen Akteuren und Kalzium, Phosphat, Vitamin D und Vitamin K2 und der Verkalkung von Gefäßen und Weichteilen beeinflusste unweigerlich unsere Therapien. Dieser erste Teil des Beitrags verschafft einen Überblick über die neuesten Erkenntnisse zum Phosphat-Sensing, die Rolle von FGF23 und Klotho und die Besonderheiten des Vitamin-D- und Vitamin-K-Stoffwechsels bei Gesundheit und chronischer Nierenerkrankung.

Purpose The purpose of this paper was to review the literature concerning the treatment of chronic kidney disease-mineral bone disorder (CKD-MBD) in the elderly peritoneal dialysis (PD) patient. Results Chronic kidney disease-mineral bone disorder is a major problem in the elderly PD patient, with its associated increased fracture risk, vascular calcification, and accelerated mortality fracture risk. Peritoneal dialysis, however, bears a lower risk than hemodialysis (HD). The approach to CKD-MBD prophylaxis and treatment in the elderly PD patient is similar to other CKD patients, with some important differences. Avoidance of hypercalcemia, hyperphosphatemia, and hyperparathyroidism is important, as in other CKD groups, and is generally easier to attain. Calcium-free phosphate binders are recommended for normocalcemic and hypercalcemic patients. Normalization of vitamin D levels to > 75 nmol/L (> 30 pg/L) and low-dose active vitamin D therapy is recommended for all patients. Hyperparathryoidism is to be avoided by using active vitamin D and cinacalcet. Particular attention should be paid to treating protein malnutrition. Fracture prophylaxis (exercise, use of walkers, dwelling modifications) are important. Hypomagnesemia is common in PD and can be treated with magnesium supplements. Vitamin K deficiency is also common and has been identified as a cause of vascular calcification. Accordingly, warfarin treatment for this age group is problematic. Conclusion While treatment principles are similar to other dialysis patient groups, physicians should be aware of the special problems of the elderly group.

Management of chronic kidney disease-mineral bone disorder (CKD-MBD) can be difficult in patients with chronic kidney disease (CKD). This review aims to explain why the control of disturbed calcium, phosphate, parathyroid hormone and vitamin D metabolism is important in CKD patients. The available means to control these parameters include diet, phosphate binders, native Vitamin D, active Vitamin D derivatives and calcimimetics. However, no single measure is not enough and concerted efforts give the best result. Ibrahim Cardiac Med J 2012; 2(2): 37-40

Normal Serum Calcium

The kidneys play an important role in maintaining normal serum calcium (Ca) and phosphorous (P) concentrations. Chronic kidney disease (CKD) is associated with significant disturbances in bone and mineral metabolism, leading to altered serum concentrations of Ca, P, vitamin D and parathyroid hormone (PTH)1,2,3. These changes are initially detected when the glomerular filtration rate (GFR) falls to ≤60 mL/min and are nearly uniform as GFR drops to <30ml/min2,3. This leads to a number of bone abnormalities previously called “renal osteodystrophy”, renamed as CKD-Mineral Bone Disorder (CKD-MBD) by National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF KDOQI) consensus group4 . CKD-MBD is a systemic disorder manifested by either one or a combination of a) abnormalities of Ca, P, PTH or vitamin D metabolism, b) abnormalities in bone turnover, mineralization, volume, linear growth or strength c) vascular or soft tissue calcification. This has over time been expanded to include left ventricular hypertrophy, hypertension, immune dysfunction and inflammation5,6.

Purpose of review: (1) To provide commentary on the 2017 update to the Kidney Disease Improving Global Outcomes (KDIGO) 2017 Clinical Practice Guideline Update for the Diagnosis, Evaluation, Prevention, and Treatment of Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD); (2) to apply the evidence-based guideline update for implementation within the Canadian health care system; (3) to provide comment on the care of children with chronic kidney disease (CKD); and (4) to identify research priorities for Canadian patients. Sources of information: The KDIGO 2017 Clinical Practice Guideline Update for the Diagnosis, Evaluation, Prevention, and Treatment of CKD-MBD. Methods: The commentary committee co-chairs selected potential members based on their knowledge of the Canadian kidney community, aiming for wide representation from relevant disciplines, academic and community centers, and different geographical regions. Key findings: We agreed with many of the recommendations in the clinical practice guideline on the diagnosis, evaluation, prevention, and treatment of CKD-MBD. However, based on the uncommon occurrence of abnormalities in calcium and phosphate and the low likelihood of severe abnormalities in parathyroid hormone (PTH), we recommend against screening and monitoring levels of calcium, phosphate, PTH, and alkaline phosphatase in adults with CKD G3. We suggest and recommend monitoring these parameters in adults with CKD G4 and G5, respectively. In children, we agree that monitoring for CKD-MBD should begin in CKD G2, but we suggest measuring ionized calcium, rather than total calcium or calcium adjusted for albumin. With regard to vitamin D, we suggest against routine screening for vitamin D deficiency in adults with CKD G3-G5 and G1T-G5T and suggest following population health recommendations for adequate vitamin D intake. We recommend that the measurement and management of bone mineral density (BMD) be according to general population guidelines in CKD G3 and G3T, but we suggest against routine BMD testing in CKD G4-G5, CKD G4T-5T, and in children with CKD. Based on insufficient data, we also recommend against routine bone biopsy in clinical practice for adults with CKD or CKD-T, or in children with CKD, although we consider it an important research tool. Limitations: The committee relied on the evidence summaries produced by KDIGO. The CSN committee did not replicate or update the systematic reviews.
