Abstract Background and Aims Advanced stages of chronic kidney disease (CKD) are constantly characterized by a mineral and bone disorders (MBD) syndrome concerning a complex systemic condition that includes laboratory abnormalities of bone and mineral metabolism involving calcium, phosphorus, parathyroid hormone (PTH), or vitamin D; abnormalities in bone turnover, mineralization, volume, or strength; extra-skeletal calcifications, such as vascular or other soft tissue. CKD-MBD syndrome determines relevant consequences in terms of fragility fractures, cardiovascular events and higher mortality. The nephrologist's awareness of CKD-MBD diagnostic and management tools and therapeutic strategies is key to improving CKD patients’ prognosis and outcomes. Method A new national survey (composed of 17 online questions) was conducted among Italian nephrologists to investigate the reference laboratory availability of bone turnover markers (BTMs), the clinical attitude on secondary hyperparathyroidism (sHPT) management, and the CKD-MBD therapeutic approach in different stages of CKD and dialysis patients. Results 89 Italian nephrologists participated in the survey. The reference laboratories largely fulfill the biomarkers request of ionized calcium (97.7%), phosphorus (100%), PTH (100%), alkaline phosphatase (ALP) (100%), magnesium (100%), 25-OH and 1,25-OH vitamin D levels (92.1%; 53.9%); while most of the hospital laboratories do not regularly support the availability of specific BTMs, both for diagnosis and monitoring the bone resorption and formation (Fig. 1)—such as bone ALP (75.3%), calcifediol (37.1%), calcitriol (40.5%), fibroblast growth factor-23 (FGF-23) (intact 9% and c-terminal 4.5%), vitamin K (33.7%), Klotho (6.75%, soluble 4.5%), osteocalcin (38.2%), matrix gla protein (10.1%), tartrate-resistant acid phosphatase 5b (TRAP-5b) (6.75%), cross-linked collagen type I peptide (CTX) (32.6%) and procollagen type 1 n-terminal propeptide (P1NP) (10.1%). The nephrologist's attitude to start management and treatment of sHPT is revealed to be mainly led by KDOQI (n = 42, 47%) and KDIGO (n = 39, 44%) guidelines considering their PTH cut-off values; in 53.9% of clinicians the measure of PTH levels is then performed every 3 months according to KDOQI guidelines. In relation to the definition of high turnover metabolic bone disease by BTMs, this metabolic pattern is identified in > 50% and 30-40% of patients with CKD 4-5D by 31.5% and 21.4% of nephrologists, respectively. 65% of clinicians currently considered ALP of equal importance as alterations of PTH as a predictor of fracture events. Other biomarkers, such as FGF-23, P1NP or TRAP-5b, emerge to not be still used in regular clinical practice. In patients diagnosed with CKD-MBD and skeletal fragility, 76.4% of nephrologists consider the AIFA (Italian Medicines Agency) note 79 to support osteoporosis treatment. The therapeutic strategies of CKD-MBD include the administration of vitamin D (e.g. cholecalciferol 27-37.1%, calcifediol 9-12.4%, calcitriol 42.7-55.1%) and its analogues (e.g. paricalcitol 23.6-52.8%) and the use of antiresorptive agents (e.g. alendronate 3.4%-23.6%, denosumab 22.5%-30.3%) with variable frequencies among different advanced CKD stages and for those patients on peritoneal or hemodialysis (Fig. 2). Conclusion Results present a suboptimal use of BTMs and a current heterogeneous therapeutic management of CKD-MBD syndrome and renal osteodystrophy in Italian clinical practice. The survey represents a starting point of work to further implement awareness of diagnostic and therapeutic issues of CKD-MBD.
