          Abstract

          Dialysis patients are at increased risk for hip fractures. Because changes in treatment of metabolic bone disease in this population may have impacted bone fragility, this study aims to analyze the longitudinal risk for fractures in hemodialysis (HD) and peritoneal dialysis (PD) patients.

          The three-year incidence of fracture in chronic kidney disease.

          Knowing a person's fracture risk according to their kidney function, gender, and age may influence clinical management and decision-making. Using healthcare databases from Ontario, Canada, we conducted a cohort study of 679,114 adults of 40 years and over (mean age 62 years) stratified at cohort entry by estimated glomerular filtration rate ((eGFR) 60 and over, 45-59, 30-44, 15-29, and under 15 ml/min per 1.73 m(2)), gender, and age (40-65 and over 65 years). The primary outcome was the 3-year cumulative incidence of fracture (proportion of adults who fractured (hip, forearm, pelvis, or proximal humerus) at least once within 3-years of follow-up). Additional analyses examined the fracture incidence per 1000 person-years, hip fracture alone, stratification by prior fracture, stratification by eGFR and proteinuria, and 3-year cumulative incidence of falls with hospitalization. The 3-year cumulative incidence of fracture significantly increased in a graded manner in adults with a lower eGFR for both genders and both age groups. The 3-year cumulative incidence of fracture in women over 65 years of age across the 5 eGFR groups were 4.3%, 5.8%, 6.5%, 7.8%, and 9.6%, respectively. Corresponding estimates for men over 65 years were 1.6%, 2.0%, 2.7%, 3.8%, and 5.0%, respectively. Similar graded relationships were found for falls with hospitalization and additional analyses. Thus, many adults with chronic kidney disease will fall and fracture. Results can be used for prognostication and guidance of sample size requirements for fracture prevention trials.

            Biomolecular basis of the role of diabetes mellitus in osteoporosis and bone fractures.

            Osteoporosis has become a serious health problem throughout the world which is associated with an increased risk of bone fractures and mortality among the people of middle to old ages. Diabetes is also a major health problem among the people of all age ranges and the sufferers due to this abnormality increasing day by day. The aim of this review is to summarize the possible mechanisms through which diabetes may induce osteoporosis. Diabetes mellitus generally exerts its effect on different parts of the body including bone cells specially the osteoblast and osteoclast, muscles, retina of the eyes, adipose tissue, endocrine system specially parathyroid hormone (PTH) and estrogen, cytokines, nervous system and digestive system. Diabetes negatively regulates osteoblast differentiation and function while positively regulates osteoclast differentiation and function through the regulation of different intermediate factors and thereby decreases bone formation while increases bone resorption. Some factors such as diabetic neuropathy, reactive oxygen species, Vitamin D, PTH have their effects on muscle cells. Diabetes decreases the muscle strength through regulating these factors in various ways and ultimately increases the risk of fall that may cause bone fractures.

              Epidemiology and mortality of hip fracture among patients on dialysis: Taiwan National Cohort Study.

              Chronic kidney disease increases the risk for hip fractures. Hip fractures are associated with increased mortality, decreased quality of life, and higher economic burden. To determine whether dialysis modality is associated with a higher incidence of hip fractures in patients with end-stage renal disease (ESRD), we used the Taiwan National Health Insurance Research Database to examine the records of 51,473 patients who began dialysis between 1999 and 2005. The patients were followed until death, transplantation, dialysis cessation, or 31 December 2008. The follow-up period was (mean±SD) 4.14±2.48 years. The cumulative incidence rate of hip fracture was calculated using Kaplan-Meier methods. Predictors of hip fracture were determined using Cox models. During the study period, 1903 patients had a hip fracture. The overall incidence rate of hip fracture was 89.21/10,000 patient-years. Patients on hemodialysis (HD) had a 31% higher incidence of hip fracture than those on peritoneal dialysis (PD) (HR 1.31, 95% CI: 1.01-1.70). Patients ≥65 years old had more than 13 times the risk of a hip fracture than did those 18-44 years old (HR: 13.65; 95% CI: 10.12-18.40). Other factors that increased the risk of a hip fracture were a prior hip fracture (HR: 1.44; 95% CI: 1.15-1.80), osteoporosis (HR: 1.24; 95% CI: 1.07-1.45), DM (HR: 1.66; 95% CI: 1.51-1.83), and liver cirrhosis (HR: 1.37, 95% CI: 1.15-1.64). The overall in-hospital mortality rate was 3.2%. The cumulative survival rates after a hip fracture were 74.6% at one year and only 29.6% at seven years. Our findings supported the notion that being on HD is a risk for hip fracture. Additionally, old age, female gender, a prior hip fracture, osteoporosis, DM and liver cirrhosis were also risk factors for hip fracture in patients with ESRD and undergoing dialysis.
