Bone health in chronic kidney disease-mineral and bone disorder: a clinical case seminar and update.

Intern Med J 2018 Dec;48(12):1435-1446

Department of Endocrinology and Diabetes, St Vincent's Hospital Melbourne, Melbourne, Victoria, Australia.

The metabolic abnormalities affecting bone in the setting of chronic kidney disease (CKD) are complex with overlapping and interacting aetiologies and have challenging diagnostic and management strategies. Disturbances in calcium, phosphate, fibroblast growth factor 23, parathyroid hormone concentrations and vitamin D deficiency are commonly encountered and contribute to the clinical syndromes of bone disorders in CKD, including hyperparathyroidism, osteomalacia, osteoporosis and adynamic bone disease. Mineral and bone abnormalities may also persist or arise de novo post-renal transplantation. Read More

Bone histomorphometry in the evaluation of osteomalacia.

Bone Rep 2018 Jun 17;8:125-134. Epub 2018 Mar 17.

Bone & Mineral Research Laboratory, Henry Ford Health System, Detroit, MI, 48201, United States.

With the widespread use of measurement of bone mineral density to detect, diagnose, and monitor therapy in the management of osteoporosis, bone histomorphometry has largely been relegated to research settings and academic pursuits. However, bone density measurement cannot distinguish between osteoporosis and other metabolic bone disorders such as different types of osteomalacia, osteitis fibrosa, renal osteodystrophy, hypophosphatasia, and Paget's disease of bone. Furthermore, bone density test cannot tell us anything about microarchitecture of bone, tissue level dynamics, bone cellular activity, bone mineralization and bone remodeling, understanding of which is essential to make a specific diagnosis of a suspected metabolic bone disease, to evaluate beneficial (or adverse) effects of various therapies, treatment (medical or surgical) decisions in hyperparathyroid states.

Targeted resequencing of phosphorus metabolism‑related genes in 86 patients with hypophosphatemic rickets/osteomalacia.

Int J Mol Med 2018 Sep 13;42(3):1603-1614. Epub 2018 Jun 13.

Metabolic Bone Disease and Genetic Research Unit, Department of Osteoporosis and Bone Diseases, Shanghai Key Clinical Center for Metabolic Disease, Shanghai Jiao Tong University Affiliated Sixth People's Hospital, Shanghai 200233, P.R. China.

Hypophosphatemic rickets/osteomalacia is characterized by defective renal phosphate reabsorption and abnormal bone mineralization. Hypophosphatemic rickets/osteomalacia consists of inherited and acquired forms, many of which have unknown aetiology. In the present study, next‑generation sequencing‑based resequencing was used on samples from Chinese subjects with hypophosphatemic rickets/osteomalacia, aiming to detect the spectrum of pathogenic genes in these patients.

Targeting Fibroblast Growth Factor 23 Signaling with Antibodies and Inhibitors, Is There a Rationale?

Authors:
Seiji Fukumoto

Front Endocrinol (Lausanne) 2018 20;9:48. Epub 2018 Feb 20.

Department of Molecular Endocrinology, Fujii Memorial Institute of Medical Sciences, Institute of Advanced Medical Sciences, Tokushima University, Tokushima, Japan.

Fibroblast growth factor 23 (FGF23) is a phosphotropic hormone mainly produced by bone. FGF23 reduces serum phosphate by suppressing intestinal phosphate absorption through reducing 1,25-dihydroxyvitamin D and proximal tubular phosphate reabsorption. Excessive actions of FG23 result in several kinds of hypophosphatemic rickets/osteomalacia including X-linked hypophosphatemic rickets (XLH) and tumor-induced osteomalacia. Read More

The Use of Vitamin D Metabolites and Analogues in the Treatment of Chronic Kidney Disease.

Endocrinol Metab Clin North Am 2017 12 29;46(4):983-1007. Epub 2017 Sep 29.

Division of Nephrology and Hypertension, Department of Medicine, Mayo Clinic, 200 First Street SW, Rochester, MN 55901, USA; Department of Biochemistry and Molecular Biology, Mayo Clinic, 200 First Street SW, Rochester, MN 55901, USA. Electronic address:

Chronic kidney disease (CKD) and end-stage renal disease (ESRD) are associated with abnormalities in bone and mineral metabolism, known as CKD-bone mineral disorder. CKD and ESRD cause skeletal abnormalities characterized by hyperparathyroidism, mixed uremic osteodystrophy, osteomalacia, adynamic bone disease, and frequently enhanced vascular and ectopic calcification. Hyperparathyroidism and mixed uremic osteodystrophy are the most common manifestations due to phosphate retention, reduced concentrations of 1,25-dihydroxyvitamin D, intestinal calcium absorption, and negative calcium balance.

Authors:
Lu Song

Adv Clin Chem 2017;82:1-46. Epub 2017 Aug 7.

David Geffen School of Medicine, University of California, Los Angeles, CA, United States. Electronic address:

Calcium and inorganic phosphate are of critical importance for many body functions, thus the regulations of their plasma concentrations are tightly controlled by the concerted actions of reabsorption/excretion in the kidney, absorption in the intestines, and exchange from bone, the major reservoir for calcium and phosphate in the body. Parathyroid hormone (PTH) and 1,25-dihydroxyvitamin D (1,25(OH)D) control calcium homeostasis, whereas PTH, 1,25(OH)D, and bone-derived fibroblast growth factor 23 (FGF 23) control phosphate homeostasis. Hypoparathyroidism can cause hypocalcemia and hyperphosphatemia, whereas deficient vitamin D actions can cause osteomalacia in adults and rickets in children. Read More

Bilateral Subcapital Femoral Neck Fracture in a 28 Year Old Postpartum Woman.

Med Arch 2017 Apr;71(2):151-153

Department of Orthopedics and Traumatology, General hospital Niksic, Montenegro.

Introduction: Subcapital femoral neck fractures are associated with high morbidity and mortality. These fractures mostly occur as a result of a high-force impact from traffic accidents and a fall from a great height, though non-traumatic forms are described in transient osteoporosis during the second half of pregnancy, in convulsions during electric shock, eclampsia, hypocalcemia, osteomalacia, renal osteodystrophy and myeloma.

Case Report: In this report we present a bilateral subcapital femoral neck fracture in a woman sustained two days after delivery. Read More

Fractures and Osteomalacia in a Patient Treated With Frequent Home Hemodialysis.

Am J Kidney Dis 2017 Sep 9;70(3):445-448. Epub 2017 May 9.

Department of Pediatrics, David Geffen School of Medicine at UCLA, Los Angeles, CA.

Bone deformities and fractures are common consequences of renal osteodystrophy in the dialysis population. Persistent hypophosphatemia may be observed with more frequent home hemodialysis regimens, but the specific effects on the skeleton are unknown. We present a patient with end-stage renal disease treated with frequent home hemodialysis who developed severe bone pain and multiple fractures, including a hip fracture and a tibia-fibula fracture complicated by nonunion, rendering her nonambulatory and wheelchair bound for more than a year.

Imaging in Chronic Kidney Disease-Metabolic Bone Disease.

Semin Dial 2017 07 5;30(4):361-368. Epub 2017 Apr 5.

Department of Medicine, NorthShore University HealthSystem, University of Chicago Pritzker School of Medicine, Chicago, Illinois.

Musculoskeletal manifestations in chronic kidney disease (CKD) are the result of a series of complex alterations in mineral metabolism, which has been defined as chronic kidney disease - mineral and bone-related disorder (CKD-MBD). Biochemical assessment and, at times, bone biopsy remains the mainstay of disease assessment, however, radiological imaging is an important adjunct in evaluating disease severity. This review aims to illustrate the radiological features of CKD-MBD, such as secondary hyperparathyroidism, osteomalacia, adynamic bone disease, osteopenia, and extra-skeletal calcifications.

Imaging Findings of Metabolic Bone Disease.

Radiographics 2016 Oct;36(6):1871-1887

From the Division of Musculoskeletal Imaging and Intervention, Department of Radiology (C.Y.C., D.I.R., S.V.K., A.J.H.), and the Pediatric Endocrine Division, Department of Pediatrics (D.M.M.), Massachusetts General Hospital, 55 Fruit St, Yawkey 6E, Boston, MA 02114; and the Department of Radiology, St. Luke's International Hospital, Tokyo, Japan (A.H.).

Metabolic bone diseases are a diverse group of diseases that result in abnormalities of (a) bone mass, (b) structure mineral homeostasis, (c) bone turnover, or (d) growth. Osteoporosis, the most common metabolic bone disease, results in generalized loss of bone mass and deterioration in the bone microarchitecture. Impaired chondrocyte development and failure to mineralize growth plate cartilage in rickets lead to widened growth plates and frayed metaphyses at sites of greatest growth. Read More

Division of Endocrinology, Diabetes, and Metabolism, University of Massachusetts, 55 Lake Avenue North, Worcester, MA 01655, USA.

The Kidney Disease: Improving Global Outcomes (KDIGO) work group released recommendations in 2006 to define the bone-related pathology associated with chronic kidney disease as renal osteodystrophy. In 2009, KDIGO released revised clinical practice guidelines which redefined systemic disorders of bone and mineral metabolism due to chronic kidney disease as chronic kidney disease-mineral and bone disorders. Conditions under this overarching term include osteitis fibrosa cystica, osteomalacia, and adynamic bone disease. Read More

A Practical Approach to Vitamin D Deficiency and Rickets.

Endocr Dev 2015 12;28:119-33. Epub 2015 Jun 12.

Department of Paediatric Endocrinology, Royal London Hospital, Whitechapel, London, UK.

Rickets is a condition in which there is failure of the normal mineralisation (osteomalacia) of growing bone. Whilst osteomalacia may be present in adults, rickets cannot occur. It is generally caused by a lack of mineral supply, which can either occur as a result of the deficiency of calcium (calciopaenic rickets, now known as parathyroid hormone-dependent rickets) or of phosphate (phosphopaenic rickets, now called FGF23-dependent rickets).

Can one evaluate bone disease in chronic kidney disease without a biopsy?

Curr Opin Nephrol Hypertens 2014 Jul;23(4):431-7

Department of Medicine, Columbia University Medical Center, New York, New York, USA.

Purpose Of Review: Chronic kidney disease-mineral and bone disorder (CKD-MBD) is a complex disorder of bone and mineral metabolism that results in an excess risk of fractures, cardiovascular events and mortality. The management of the bone disorder aspect of CKD-MBD may require bone biopsy to determine appropriate treatment strategies. However, it is unclear when biopsy may be necessary and whether or not state-of-the art imaging and serologic testing can supplant the bone biopsy as a tool to assist with management decisions.

Bisphophonates in CKD patients with low bone mineral density.

ScientificWorldJournal 2013 31;2013:837573. Epub 2013 Dec 31.

Division of Nephrology, Department of Medicine, Cardinal Tien Hospital, School of Medicine, Fu-Jen Catholic University, 362 Chung-Cheng Road, Hsin-Tien, New Taipei 231, Taiwan.

Patients with chronic kidney disease-mineral and bone disorder (CKD-MBD) have a high risk of bone fracture because of low bone mineral density and poor bone quality. Osteoporosis also features low bone mass, disarranged microarchitecture, and skeletal fragility, and differentiating between osteoporosis and CKD-MBD in low bone mineral density is a challenge and usually achieved by bone biopsy. Bisphosphonates can be safe and beneficial for patients with a glomerular filtration rate of 30 mL/min or higher, but prescribing bisphosphonates in advanced CKD requires caution because of the increased possibility of low bone turnover disorders such as osteomalacia, mixed uremic osteodystrophy, and adynamic bone, even aggravating hyperparathyroidism.

Phosphate is widely distributed in the body and an adequate balance is required for maintaining essential cellular and organ functions. Dysregulation of phosphate balance, either in the form of hypophosphatemia or hyperphosphatemia can induce disorders ranging from rickets/osteomalacia to cardiovascular calcification. A physiologic phosphate balance is delicately maintained by multiorgan cross-talks among the intestine, kidney, and bone. Read More

Pathophysiology of chronic kidney disease-mineral and bone disorder.

Joint Bone Spine 2012 Dec 21;79(6):544-9. Epub 2012 Nov 21.

INSERM U1059, université de Lyon, Saint-Étienne cedex 2, France.

Chronic kidney disease (CKD) alters the metabolism of several minerals, thereby inducing bone lesions and vessel-wall calcifications that can cause functional impairments and excess mortality. The histological bone abnormalities seen in CKD, known as renal osteodystrophy, consist of alterations in the bone turnover rate, which may be increased (osteitis fibrosa [OF]) or severely decreased (adynamic bone disease [AD]); abnormal mineralization (osteomalacia [OM]), and bone loss. Secondary hyperparathyroidism is related to early phosphate accumulation (responsible for FGF23 overproduction by bone tissue), decreased calcitriol production by the kidneys, and hypocalcemia.

Current concepts and management strategies in chronic kidney disease-mineral and bone disorder.

South Med J 2012 Sep;105(9):479-85

Division of Nephrology, Department of Medicine, Drexel University College of Medicine and Hahnemann University Hospital, Philadelphia, PA 19102, USA.

The term renal osteodystrophy describes the pathological changes in bone structure in chronic kidney disease (CKD); however, this term fails to describe adequately the adverse changes in mineral and hormonal metabolism in CKD that have grave consequences for patient survival. CKD-mineral and bone disorder (CKD-MBD) is a broader, newly defined term that should be used instead of renal osteodystrophy to define the mineral, bone, hormonal, and calcific cardiovascular abnormalities that are seen in CKD. The new paradigm in the management of renal bone disease is to "think beyond the bones" and strive to improve cardiovascular outcomes and survival. Read More

Clinical outcomes of recipients with aplastic bone disease after renal transplantation.

Transplant Proc 2012 Apr;44(3):680-3

Department of Urology, Kidney Center, Toda Central General Hospital, Saitama, Japan.

Objectives: We expect that if chronic renal failure (CRF) is improved after renal transplantation (RTx), dialysis osteopathy bone lesions would also recover to normal. Nevertheless, it is controversial whether bone lesions really improve after RTx. In this study, we evaluated whether pathological dialysis osteopathy improved after RTx. Read More

More than 300 million years ago, vertebrates emerged from the vast oceans to conquer gravity and the dry land. With this transition, new adaptations occurred that included ingenious changes in reproduction, waste secretion, and bone physiology. One new innovation, the egg shell, contained an ancestral protein (ovocleidin-116) that likely first appeared with the dinosaurs and was preserved through the theropod lineage in modern birds and reptiles.

[Is bone biopsy necessary for the diagnosis of metabolic bone diseases? Necessity of bone biopsy].

Clin Calcium 2011 Sep;21(9):1388-92

Ito Bone Histomorphometry Institute, Japan.

Histological analysis of undecalcified bone biopsy specimens is a valuable clinical and research tool for studying the etiology, pathogenesis and treatment of metabolic bone diseases. In case of osteoporosis, bone biopsy is not usually required for the diagnosis ; however, bone histomorphometry may be useful in rare cases with unusual skeletal fragility. Bone histomorphometry also provides valuable information on the mechanism of action, safety and efficacy of new anti-osteoporosis drugs. Read More

Fibroblast growth factor 23 as a phosphotropic hormone and beyond.

J Bone Miner Metab 2011 Sep 6;29(5):507-14. Epub 2011 Aug 6.

Division of Nephrology and Endocrinology, Department of Medicine, University of Tokyo Hospital, Bunkyo-ku, Tokyo, Japan.

Fibroblast growth factor 23 (FGF23) is produced by bone and reduces serum phosphate by inhibiting proximal tubular phosphate reabsorption and intestinal phosphate absorption. Excess actions of FGF23 cause several kinds of hypophosphatemic rickets/osteomalacia while deficient actions of FGF23 result in hyperphosphatemic tumoral calcinosis. In addition, FGF23 has been shown to prevent the development of hyperphosphatemia during the progression of chronic kidney disease-mineral and bone disorder. Read More

Department of Clinical Science, Sapienza University of Rome, Italy.

Renal tubular diseases may present with osteopenia, osteoporosis or osteomalacia, as a result of significant derangements in body electrolytes. In case of insufficient synthesis of calcitriol, as in renal failure, the more complex picture of renal osteodystrophy may develop. Hypothetically, also disturbed renal production of BMP-7 and Klotho could cause bone disease. Read More

Bone histomorphometry: a concise review for endocrinologists and clinicians.

Arq Bras Endocrinol Metabol 2010 Mar;54(2):87-98

Hospital de Clínicas, Universidade Federal do Paraná, Curitiba, PR, Brasil.

Bone histomorphometry is a quantitative histological examination of an undecalcified bone biopsy performed to obtain quantitative information on bone remodeling and structure. Labeling agents taken before the procedure deposit at sites of bone formation allowing a dynamic analysis. Biopsy is indicated to make the diagnosis of subclinical osteomalacia, to characterize the different forms of renal osteodystrophy and to elucidate cases of unexplained skeletal fragility. Read More

Relationship between bone histology and markers of bone and mineral metabolism in African-American hemodialysis patients.

Clin J Am Soc Nephrol 2009 Sep;4(9):1484-1493

Division of Nephrology and Hypertension, Henry Ford Hospital, Detroit, Michigan, USA.

Background And Objectives: Racial differences in mineral metabolism exist in the chronic kidney disease population, especially as it relates to intact parathyroid hormone (iPTH) levels. Few data exist on the relationship of these markers to bone biopsy findings in African-American (AA) hemodialysis patients across the spectrum of renal osteodystrophy (ROD).

Design, Setting, Participants, & Measurements: In prevalent AA hemodialysis subjects, we prospectively evaluated subjects by performing transiliac bone biopsy and correlating biochemical and clinical data to bone histology. Read More

Department of Medicine, University of Washington Medical Center, Seattle, WA 98195-6426, USA.

On bone biopsies from patients with chronic kidney disease, measurements are made of the turnover, mineralization, and volume. Turnover depends on the bone formation rate and bone resorption rate; the former can be measured using tetracycline labelling. The osteoid width and bone apposition rate determine the mineralization rates. Read More

Bisphosphonates in chronic kidney disease; balancing potential benefits and adverse effects on bone and soft tissue.

Clin J Am Soc Nephrol 2009 Jan 5;4(1):221-33. Epub 2008 Nov 5.

Department of Nephrology, Monash Medical Centre, Clayton, Victoria, Australia.

Cardiovascular disease is highly prevalent in chronic kidney disease (CKD) and is often associated with increased vascular stiffness and calcification. Recent studies have suggested a complex interaction between vascular calcification and abnormalities of bone and mineral metabolism, with an inverse relationship between arterial calcification and bone mineral density (BMD). Although osteoporosis is recognized and treated in CKD 1 to 3, the interpretation of BMD levels in the osteoporotic range is controversial in CKD 4, 5, and 5D when renal osteodystrophy is generally present.

Metabolic bone disease: a review and update.

Instr Course Lect 2008 ;57:575-93

Treadwell Library and Smith-Peterson Library, Massachusetts General Hospital, Boston, Massachusetts, USA.

Understanding the structure and formation of bone and the metabolic diseases that cause intrinsic biochemical alterations and ultimate damage to the skeletal system is an essential part of orthopaedic education and knowledge. Metabolic bone diseases such as rickets, osteomalacia, renal osteodystrophy, hyperparathyroidism, and osteoporosis often lead to subtle alterations in the patient's clinical status and to severe and disabling changes in the patient's bone structure. It is essential that orthopaedists recognize these conditions, provide a correct diagnosis, and use appropriate preventive and therapeutic treatments. Read More

Bilateral undisplaced insufficiency neck of femur fractures associated with short-term steroid use: a case report.

J Med Case Rep 2008 Mar 11;2:79. Epub 2008 Mar 11.

Registrar, Department of Trauma and Orthopaedics, St Georges Hospital, Blackshaw Rd, London, UK.

Introduction: We present an interesting and unusual case of a 61-year-old woman with bilateral, undisplaced, stress neck of femur fractures associated with short-term steroid use. Insufficiency fractures of the neck of femur without preceding trauma have been described in the literature, although bilateral involvement is infrequent. These fractures have been associated with strenuous exercise, seizures, renal osteodystrophy, fluoride treatment, long-term corticosteroid use, amenorrhoea, abnormal anatomy and osteomalacia due to nutritional and/or hormonal factors.
