Abstract
Osteoporosis and osteopenia are common in lung transplant (LTx) recipients, with a significantly increased incidence compared to other non-lung solid organ transplant patients. Despite high fracture rates, including in patients treated with antiresorptive medications, there are limited data on the use of anabolic treatments in LTx recipients. We present clinical, biochemical and bone mineral density data for 3 patients with severe osteoporosis treated with teriparatide 20 micrograms daily for 18 months post-LTx. Prednisone doses ranged between 5 and 10 mg daily throughout the treatment period. All patients had previously received zoledronate (last dose 12-24 months prior to teriparatide). Bone turnover was monitored repeatedly during treatment in one patient. Following completion of teriparatide, all patients received consolidation treatment with 4 mg zoledronate. Bone density was measured prior and within 6 to 12 months after completion of teriparatide. All 3 patients experienced an increase in bone density at the lumbar spine (median +12%; range, 2%-14%) and total proximal femur (median +8%, range, 8%-10%). No adverse effects were observed. Given that severe osteoporosis is highly prevalent in LTx patients, teriparatide should be further studied as a treatment in this clinical setting. Our cases suggest it is safe and effective.

Abstract
Fractures negatively impact quality of life and survival. We hypothesized that recipient frailty score and genetic profile measured before transplant would predict risk of fracture after lung transplant. We conducted a retrospective cohort study of bone mineral density (BMD) and fracture among lung transplant recipients at a single center. The association between predictors and outcomes were assessed by multivariable time-dependent Cox models or regression analysis. Among the 284 participants, osteoporosis and fracture were highly prevalent. Approximately 59% of participants had posttransplant osteopenia, and 35% of participants developed at least 1 fracture. Low BMD was associated with a polygenic osteoporosis risk score, and the interaction between genetic score and BMD predicted fracture. Pretransplant frailty was associated with risk for spine and hip fracture, which were not associated with chronic lung allograft dysfunction or death. Chest fractures were the most frequent type of fracture and conferred a 2.2-fold increased risk of chronic lung allograft dysfunction or death (time-dependent P < .001). Pneumonia, pleural effusions, and acute rejection frequently occurred surrounding chest fracture. Pretransplant frailty and recipient genotype may aid clinical risk stratification for fracture after transplant. Fracture carries significant morbidity, underscoring the importance of surveillance and osteoporosis prevention.

[PMID: 33189560 DOI: 10.1016/j.jocd.2020.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Revised: 10/11/2020] [Accepted: 10/12/2020] [Indexed: 11/18/2022]
Abstract
Osteoporosis is prevalent among lung transplant candidates and is exacerbated post-transplant by immunosuppressive therapy. Low bone mineral density (BMD) is a well-recognized surrogate for fragility fracture risk, which is associated with significant morbidity and mortality. Intravenous zoledronic acid (ZA) effectively reduces BMD loss and prevents fractures in postmenopausal osteoporosis. Many groups, ours included, prophylactically treat lung transplant recipients (LTR) with bisphosphonates, but no documented consensus currently exists. Our protocol comprises ZA every 6-months from transplant wait-listing, with interval reassessment to guide ongoing treatment. We evaluate the impact of a dose of ZA within 6 months of transplantation on BMD and fracture occurrence. A retrospective analysis was performed on all adult LTR from April 2012 to October 2014, of which 60 met our inclusion criteria. LTR who received ZA within 6 months of transplantation (n = 37) were compared to those who did not (n = 23), and followed up for a minimum of three years. Outcome measures were BMD change at the lumbar spine and femur (primary), and fracture occurrence (secondary). LTR treated with ZA within 6 months of transplantation experienced a median BMD change of +8.11% at the lumbar spine and +1.39% at the femur, compared to -1.20% and -3.92%, respectively, in LTR who did not receive a ZA dose within 6 months of transplantation (p = 0.002 & p = 0.008 respectively). Our findings indicate that prophylactic ZA within 6 months of transplantation prevents BMD loss in LTR.

Impact of bone-active drugs and underlying disease on bone health after lung transplantation: A longitudinal study. J Cyst Fibros 2021; 20:e100-e107. [PMID: 34366281 DOI: 10.1016/j.jcf.2021.07.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Revised: 04/15/2021] [Accepted: 07/24/2021] [Indexed: 11/23/2022]
Abstract
INTRODUCTION the effect of bone-active drugs on the risk of fragility fractures (Fx), bone mineral density (BMD) and trabecular bone score (TBS) changes in patients receiving lung transplantation (LTx) is largely unknown. This study assessed the bone-active drugs effect in patients undergoing LTx both with (CF) and without (nCF) cystic-fibrosis. METHODS We evaluated incident Fx, both clinical and morphometric vertebral Fx by spinal X-ray, BMD and trabecular bone score (TBS) in 117 patients (CF=50, nCF n = 67) before and 24-months after LTx. A bone-active therapy was proposed to all LTx candidates. RESULTS 83.8% of patients started a bone-active drug. Lumbar-spine (LS) T-score improved significantly only in treated patients (-1.4 ± 1.0 vs -2.0±1.0, p = 0.0001), whereas femur BMD and TBS remained stable in treated and not treated subjects. The rate of incident Fx was 15.3%, with no difference between treated and not treated patients. After LTx, LS T-score improved significantly only in nCF group (-1.3 ± 1.0 vs -1.8 ± 1.1, p = 0.0001), while femur remained stable in both nCF and CF groups. Patients with CF showed a significant Z-TBS increase (-3.6 ± 1.7 vs -3.0 ± 1.7, p = 0.019) and a lower Fx incidence as compared with nCF patients (4.1% vs 24.2%, p =0.003). Incident Fx were associated with nCF diagnosis (OR 7.300, CI95% 1.385-38.461, p = 0.019) regardless of prevalent Fx, previous glucocorticoid therapy and bone-active therapy introduced at least 6 months before LTx. CONCLUSIONS A prompt medical intervention helps in preventing BMD loss after LTx. As compared with nCF patients, CF patients show a TBS increase and a lower Fx risk after LTx.

Abstract
Chronic inflammation induces proinflammatory cytokine cascades. In addition to systemic inflammation, hypoxemia, hypercapnia, a catabolic metabolism, gonadal or thyroid dysfunction, musculoskeletal dysfunction and inactivity as well as vitamin D deficiency contribute to an increased risk of fragility fractures. Iatrogenic causes of osteoporosis are long-term use of inhaled or systemic glucocorticoids (GC). Inhalative GC application in asthma is often indicated in childhood and adolescence, but interstitial lung diseases such as chronic organizing pneumonia, COPD, sarcoid or rheumatic diseases with lung involvement are also treated with inhalative or oral GC. In patients with cystic fibrosis, malabsorption in the context of pancreatic insufficiency, hypogonadism and chronic inflammation with increased bone resorption lead to a decrease in bone structure. After lung transplantation, immunosuppression with GC is a risk factor.The underlying pneumological diseases lead to a change in the trabecular and cortical bone microarchitecture and to a reduction in osteological formation and resorption markers. Hypercapnia, acidosis and vitamin D deficiency can accelerate this process and thus increase the individual risk of osteoporotic fragility fractures.A bone mineral density measurement with a T‑Score < -2.5 is a threshold value for the diagnosis of osteoporosis; in contrast the vast majority of all osteoporotic fractures occur with a T‑Score > -2.5. A history of low-trauma fracture indicates osteological therapy.All antiresorptive or anabolic drugs approved in Austria for the treatment of osteoporosis are also indicated for pneumological patients with an increased fragility fracture risk of bone fractures in accordance with the national reimbursement criteria.

Abstract
BACKGROUND Little is known about long-term bone mineral density (BMD) changes and fractures in lung transplant recipients with cystic fibrosis (CF). We examined femur and lumbar spine (LS) BMD changes in men and women with CF up to 10 years post-transplant and documented post-transplant fracture prevalence. METHODS Retrospective study of individuals who had undergone a lung transplant (2000-2015) and had a pre-transplant and at least one BMD measurement after transplant. Vertebral fractures were assessed on chest computed tomography scans and other fractures abstracted from medical records. RESULTS The cohort consisted of 131 individuals; 53% males, median age: 28 years [interquartile range: 24-35] and 31% having pre-transplant low bone mass. Most recipients were given bisphosphonates after transplant with proportion reaching 94% at 10 years. Up to 10 years post-transplant, men experienced positive or little change in LS BMD, indicating minimal loss from pre-transplant values. In contrast, women displayed negative changes in BMD up to 5 years post-transplant before recovering pre-transplant BMD values by 10 years. Similar patterns were observed at the femur BMD where men demonstrated a lower bone loss and faster recovery towards pre-transplant values than women. After transplant, 88% of recipients maintained their pre-transplant bone status, 3% experienced an improvement, mostly progressing from low bone mass to normal status whereas 9% had a deterioration of their pre-transplant bone status. Twenty-seven recipients suffered fractures in the post-transplant period. CONCLUSIONS These findings underline that lung recipients with CF remain at risk of skeletal fragility despite prompt initiation of post-transplant anti-osteoporosis therapy.

Abstract
Bone loss and bone fractures are common complications after organ transplantation. Many factors contribute to the pathogenesis of transplant osteoporosis, such as bone disease preceding transplantation, immunosuppressive medications, and nutritional and lifestyle factors. This study aimed to assess the incidence of vertebral fractures before and after lung and heart transplantation. This longitudinal study analyzed 213 electronic medical records of patients who underwent lung transplantation (n = 128) and heart transplantation (n = 85) at Siena University Medical Center between January 2000 and December 2018. In lung and heart transplant recipients, the bone mineral density in the femoral sub-regions show a significant decrease at post-transplantation and at follow up visits. In both lung and heart recipients, we found an increase in the fracture incidence in the first period after transplantation (19.5% vs. 50.4% in lung recipients; 9.6% vs. 25.7% in heart recipients). Moreover, in lung recipients, vertebral fractures were predicted primarily by age, BMD at the femur, and any history of fracture. In heart recipients, vertebral fractures were predicted only by history of fracture. Our study supports the recommendations for pre-transplant osteoporosis screening in patients undergoing lung transplants, and in the first period after transplantation in heart transplant recipients.

Abstract
INTRODUCTION Solid organ transplantation is an established therapy for end-stage organ failure. Both pre-transplantation bone disease and immunosuppressive regimens result in rapid bone loss and increased fracture rates. METHODS The European Calcified Tissue Society (ECTS) formed a working group to perform a systematic review of existing literature on the consequences of end-stage kidney, liver, heart, and lung disease on bone health. Moreover, we assessed the characteristics of post-transplant bone disease and the skeletal effects of immunosuppressive agents and aimed to provide recommendations for the prevention and treatment of transplantation-related osteoporosis. RESULTS Characteristics of bone disease may differ depending on the organ that fails, but patients awaiting solid organ transplantation frequently depict a wide spectrum of bone and mineral abnormalities. Common features are a decreased bone mass and impaired bone strength with consequent high fracture risk, all of which are aggravated in the early post-transplantation period. CONCLUSION Both the underlying disease leading to end-stage organ failure and the immunosuppression regimens implemented after successful organ transplantation have detrimental effects on bone mass, quality and strength. Given existing ample data confirming the high frequency of bone disease in patients awaiting solid organ transplantation, we recommend that all transplant candidates should be assessed for osteoporosis and fracture risk and, if indicated, treated before and after transplantation. Since bone loss in the early post-transplantation period occurs in virtually all solid organ recipients and is associated with glucocorticoid administration, the goal should be to use the lowest possible dose and to taper and withdraw glucocorticoids as early as possible.

Abstract
Chronic obstructive pulmonary disease (COPD) accounts for the largest proportion of respiratory deaths worldwide and was historically the leading indication for lung transplantation. The success of lung transplantation procedures is measured as survival benefit, calculated as survival with transplantation minus predicted survival without transplantation. In chronic obstructive pulmonary disease, it is difficult to show a clear and consistent survival benefit. Increasing knowledge of the risk factors, phenotypical heterogeneity, systemic manifestations, and their management helps improve our ability to select candidates and list those that will benefit the most from the procedure.

Abstract
UNLABELLED Patients with cystic fibrosis awaiting lung transplantation for end-stage respiratory failure have high prevalence of reduced bone mineral density and fragility fracture. Suboptimal 25-hydroxyvitamin D levels could significantly contribute to the development of cystic fibrosis-related bone disease. INTRODUCTION The assessment of the prevalence of cystic fibrosis-related bone disease (CFBD) and its associated risk factors in young adults with cystic fibrosis (CF) awaiting lung transplantation for end-stage respiratory failure. METHODS Clinical characteristics, bone mineral density (BMD), the parameters of calcium metabolism, including vitamin D (25OHVitD) levels, and the presence of fragility fractures were evaluated in 42 CF patients (24 females, age 34.0 ± 8.4 years) consecutively referred as lung transplant candidates. RESULTS Mean 25OHVitD levels (54.9 ± 26.2 nmol/L) were below the reference range and hypovitaminosis D (25OHVitD < 75 nmol/L) was found in 34 patients (81%) and daily calcium intakes (median 550 mg/day) were lower than recommended. A BMD below the expected range for age (Z-score of - 2.0 or lower) and at least one prevalent fragility fracture were found in 22 patients (52.4%) and 18 patients (45.2%), respectively. The coexistence of low BMD and the presence of fracture was observed in 13 patients (31.0%). In these patients, the prevalence of nephrolithiasis was higher than in the remaining ones (p = 0.046). The presence of kidney stones was associated with a worse bone status and with severe vitamin D deficiency. In the whole sample, femoral BMD Z-scores were directly correlated with albumin-adjusted calcium (p < 0.05) and 25OHVitD levels (p < 0.01). CONCLUSIONS Despite the improvement of CF care, CFBD is still highly prevalent in young adults awaiting lung transplantation for end-stage CF. Suboptimal 25OHVitD levels could significantly contribute to the development of CFBD. The presence of nephrolithiasis could be an additional warning about the need for a careful evaluation of bone health in CF patients.

Abstract
Lung transplant prolongs life and improves quality of life in patients with end-stage lung disease. However, survival of lung transplant recipients is shorter compared to patients with other solid organ transplants, due to many unique features of the lung allograft. Patients can develop a multitude of noninfectious (e.g., primary graft dysfunction, pulmonary embolism, rejection, acute and chronic, renal insufficiency, malignancies) and infectious (i.e., bacterial, fungal, and viral) complications and require complex multidisciplinary care. This chapter discusses medical course and complications that patients might experience after lung transplantation.

Abstract
Osteoporotic fractures are well-known complications of organ transplantation. Fracture rates up to 35% have been previously reported following heart and lung transplantations. Our institutional pretransplant protocols include DXA scans, vitamin D screening, and appropriate antiresorptive therapy. We aimed to assess the incidence of fragility fractures following cardiac or lung transplantation. In a retrospective study 210 electronic medical records of patients who underwent LT (110 men, 100 women) and 105 HT (88 men, 17 women) between 2005 and 2010 were analyzed. Both clinical and radiographic fractures were recorded. DXA scans were obtained immediately after transplant. 17 out of 210 LT patients (8.0%) had fractures after transplantation and 9 out of 105 HT patients (8.6%) had fractures. The median time to the first fracture was 12 months and the mean time was 18 months for both LT and HT. In the HT recipients, the median femoral neck T score was statistically lower in the fracture group versus the nonfracture group. Similar results were seen in the LT patients. Conclusion. Our findings demonstrate a much lower incidence of fractures in heart and lung transplant recipients in comparison with earlier reports. Comprehensive bone care and early initiation of antiresorptive therapy are possible contributors to these improved outcomes.

Abstract
BACKGROUND Osteoporosis is prevalent among heart or lung transplant (HLT) candidates. Bone loss is common posttransplant, with an associated increase in fracture risk. There is a lack of consensus regarding optimal management of bone health in HLT recipients. We report bone health data in a cohort of HLT recipients before and after transplantation and make recommendations for management. METHODS Patients over the age of 20 who had a heart or lung transplant between 2000 and 2011 were identified from the New Zealand HLT Service database, and demographic data, immunosuppressive regimens, bisphosphonate use, and serial bone mineral density (BMD) data were extracted. RESULTS Pretransplant BMD was available in 52 heart and 72 lung transplant recipients; 30 and 42, respectively, also had posttransplant BMD data. Pretransplant osteopenia or osteoporosis prevalence were 23% and 8% for heart candidates and 36% and 31% for lung candidates. Posttransplant, BMD decreased significantly at the femoral neck but not at the lumbar spine in the first year, with subsequent stabilization particularly in the presence of bisphosphonate use. Pretransplant BMD was the major predictor for developing osteopenia or osteoporosis after transplantation. CONCLUSION A significant proportion of HLT recipients have osteopenia or osteoporosis pretransplant, and this persists posttransplant. Pretransplant BMD is an important predictor of subsequent osteopenia or osteoporosis development, allowing risk stratification and targeted intervention.

Abstract
Bone disease is common in recipients of kidney, heart, lung, liver, and bone marrow transplants, and causes debilitating complications, such as osteoporosis, osteonecrosis, bone pain, and fractures. The frequency of fractures ranges from 6% to 45% for kidney transplant recipients to 22% to 42% for heart, lung, and liver transplant recipients. Bone disease in transplant patients is the sum of complex mechanisms that involve both preexisting bone disease before transplant and post-transplant bone loss due to the effects of immunosuppressive medications. Evaluation of bone disease should preferably start before the transplant or in the early post-transplant period and include assessment of bone mineral density and other metabolic factors that influence bone health. This requires close coordination between the primary care physician and transplant team. Patients should be stratified based on their fracture risk. Prevention and treatment include risk factor reduction, antiresorptive medications, such as bisphosphonates and calcitonin, calcitriol, and/or gonadal hormone replacement. A steroid-avoidance protocol may be considered.

Abstract
Lung transplantation has become a proven therapeutic option for patients with end-stage lung disease, extending life and providing improved quality of life to those who otherwise would continue to be breathless and oxygen-dependent. Over the past 20 years, considerable experience has been gained in understanding the multitude of medical and surgical issues that impact upon patient survival. Today, clinicians have an armamentarium of tools to manage diverse problems such as primary graft dysfunction, acute and chronic allograft rejection, airway anastomotic issues, infectious complications, renal dysfunction, diabetes and osteoporosis, hematological and gastrointestinal problems, malignancy, and other unique issues that confront immunosuppressed solid organ transplant recipients.

Abstract
CONTEXT Bone loss and fracture are serious sequelae of organ transplantation, particularly in the first posttransplant year. Most interventional studies have been inadequately powered to detect effects on fracture. OBJECTIVE The objective of the study was to determine whether treatment with bisphosphonates (BP) or active vitamin D analogs (vitD) during the first year after transplantation reduces fracture risk and estimate the effect of these interventions on bone loss. DATA SOURCES Sources included PUBMED, MEDLINE, Cochrane Library, and abstracts from scientific meetings (presented 2003-2010). STUDY SELECTION Randomized controlled clinical trials of BP or vitD in solid organ transplant recipients were included if treatment was initiated at the time of transplantation and fracture data were collected. DATA EXTRACTION Two investigators independently extracted data and rated study quality. Fixed effect and random-effects models were used to obtain pooled estimates. DATA SYNTHESIS Eleven studies of 780 transplant recipients (134 fractures) were included. Treatment with BP or vitD reduced the number of subjects with fracture [odds ratio (OR) 0.50 (0.29, 0.83)] and number of vertebral fractures, [OR 0.24 (0.07, 0.78)]. An increase in bone mineral density at the lumbar spine [2.98% (1.31, 4.64)] and femoral neck [3.05% (2.16, 3.93)] was found with treatment. When BP trials (nine studies, 625 subjects) were examined separately, there was a reduction in number of subjects with fractures [OR 0.53 (0.30, 0.91)] but no significant reduction in vertebral fractures [OR 0.34 (0.09, 1.24)]. CONCLUSIONS Treatment with BP or vitD during the first year after solid organ transplant was associated with a reduction in the number of subjects with fractures and fewer vertebral fractures.

Abstract
Vitamin D deficiency is prevalent among patients with end-stage organ failure awaiting transplant. Low serum 25-hydroxyvitamin D (25-OHD) levels in these patients may be related to many disease-specific factors, as well as decreased sunlight exposure and limited intake of foods containing vitamin D. Low serum 25-OHD levels are also extremely common following solid organ transplantation, both during the immediate postoperative period and in long-term graft recipients. Demographic and lifestyle factors are important in determining D status in transplant recipients. Worse vitamin D status is associated with poorer general health, lower albumin, and even decreased survival among these patients. Although several studies have demonstrated that active forms of vitamin D and its analogues prevent bone loss following transplantation, the data do not show consistent benefit. These therapies may have particular utility after renal transplantation. However, given the narrow therapeutic window with respect to hypercalcemia and hypercalciuria, and the demonstrated efficacy of bisphosphonates to prevent post-transplantation bone loss, we regard these agents as adjunctive rather than primary therapy for transplantation osteoporosis. The effects of 1,25(OH)(2)D on the immune system, which are still being elucidated, may have potential for reducing infections and preventing allograft rejection after transplantation.

Abstract
Despite continuous improvement in long-term survival, there is no knowledge about risk of bone health impairment and management strategies before and after intestinal transplantation. Therefore, 147 adults were retrospectively studied via chart review; 70 long-term survivors, 53 candidates and 24 recipients with longitudinal follow-up. Evaluation process included measurement of bone mineral density (BMD) and allied biochemical markers. Both long-term survivors and candidates showed low bone mass with lower (p < 0.05) z-scores at hip, femoral neck and spine. Vitamin D deficiency and secondary hyperparathyroidism were observed in both groups. Prevalence of osteoporosis was 44% among long-term survivors and 36% in candidates with age, BMD, duration of parenteral nutrition, type of immunosuppression and rejection being significant risk factors. Fragility fractures occurred at a higher (p = 0.02) rate among long-term survivors (20%) compared to candidates (6%). The longitudinal study documented acceleration (p = 0.025) of bone loss after transplantation with a decline of 13.4% (femoral neck), 12.7% (hip) and 2.1% (spine). Alendronate reduced (p < 0.05) but did not prevent bone loss. In conclusion, intestinal transplant recipients are at risk of osteoporosis secondary to bone loss before and after transplantation. Accordingly, current management includes comprehensive preventive measures with prompt therapeutic intervention utilizing intravenous bisphosphonates or subcutaneous human PTH.

Abstract
PURPOSE Advanced lung disease increases the risk for diminished bone mineral density (BMD). The prevalence and severity of osteoporosis in lung transplant candidates is unclear. METHODS We retrospectively evaluated BMD of subjects screened for lung transplant at our institution. Observed prevalence of osteoporosis and osteopenia within our cohort was compared to the expected prevalence of each from the Third National Health and Nutrition Examination Survey (NHANES III) data matched for age, gender, and race. Lateral chest radiographs were evaluated for vertebral fractures. RESULTS High prevalence rates of osteoporosis (37%) and combined osteoporosis/osteopenia (86%) were observed. Subjects with pulmonary fibrosis had higher BMD and T-scores compared to all other subgroups. All subjects within the cohort had a higher observed combined rate of osteoporosis/osteopenia at all bone sites compared to expected rates from healthy, matched controls. Vertebral fractures were present in 23% of subjects but did not correlate with BMD or the diagnosis of osteoporosis. CONCLUSIONS Abnormal BMD was prevalent in most pre-lung transplant subjects, with striking differences noted in comparison with a healthy, matched cohort. Lateral chest radiographs in combination with BMD data give a more complete picture of bone abnormalities. Osteoporosis screening prior to lung transplantation should be performed to identify high-risk subjects for fracture and allow for intervention.

Abstract
BACKGROUND Osteoporosis is a problem after transplantation. Studies since the last year indicate that vitamin K plays a role in optimal bone health. The aim of this randomized, double blind, prospective longitudinal study was to investigate the effect of a dietary supplement with vitamin K2 (180 microg menakinon-7) on bone mass, the first year after lung and heart transplantation. METHODS After preoperative baseline investigation of bone mass and bone-related biochemistry, 35 lung and 59 heart recipients were postoperatively randomized to vitamin K2 or placebo and reinvestigated the following year. RESULTS In all recipients, 1 year after solid organ transplantation, the difference between vitamin K2 and placebo for the lumbar spine (L2-L4) bone mineral density (BMD) was 0.028 (SE 0.014) g/cm(2), P=0.055 and for L2 to L4 bone mineral content was 1.33 (SE 1.91) g/cm(2) (P=0.5). In lung recipients separately, the difference for bone mineral content was 3.39 g (SE 1.65), P=0.048 and in heart recipients 0.45 (SE 0.02) g, P=0.9 after controlling for baseline measures. In a forward stepwise linear regression analysis fitted to model differences in the L2 to L4 BMD, controlled for possible confounding variables (including use of bisphosphonate), and the only significant predictors were organ (B=-0.065 g/cm(2), P<0.001) and vitamin K2 (B=0.034 g/cm(2), P=0.019). Insufficient vitamin D status was common, and the parathyroid hormone was highest in the K2 group indicating a higher need for vitamin D. CONCLUSIONS One year of vitamin K2 supplement suggest a favorable effect on lumbar spine BMD with different response in lung and heart recipients. Vitamin D status should receive more attention.

Abstract
Cystic Fibrosis is the most common inherited genetic respiratory disorder in the Western World. Hypovitaminosis D is almost universal in CF patients, likely due to a combination of inadequate absorption, impaired metabolism, and lack of sun exposure. Inadequate levels are associated with the high prevalence of bone disease or osteoporosis in CF patients, which is associated with increased morbidity including fractures, kyphosis, and worsening pulmonary status. Treatment goals include regular monitoring 25 hydroxyvitamin D (25OHD) levels with aggressive treatment for those with levels <75 nmol/L (<30 ng/mL). More research is needed to determine optimal supplementation goals and strategies.

Abstract
A high prevalence of low bone mineralization is documented in adult patients with cystic fibrosis (CF). Osteopenia is present in up to 85% of adult patients and osteoporosis in 10% to 34%. In children, study results are discordant probably because of comparisons to different control populations and corrections for bone size in growing children. Malnutrition, inflammation, vitamin D and vitamin K deficiency, altered sex hormone production, glucocorticoid therapy, and physical inactivity are well known risk factors for poor bone health. Puberty is a critical period for bone mineralization and requires a careful follow-up to achieve optimal bone peak mass. Strategies for optimizing bone health, such as monitoring bone mineral density (BMD) and providing preventive care are necessary from childhood through adolescence to minimize CF-related bone disease in adult CF patients.

Abstract
The use of immunosuppressive agents to prevent tissue rejection may predispose patients to osteoporosis and fractures. We report a case of bilateral pathological hip fractures in a woman with osteoporosis who had undergone a bipulmonary transplant. To reduce the risk of pathological fractures, patients are given prophylaxes for osteoporosis prior to organ transplantation, but they remain at increased risk of fractures. They should be informed that this side-effect may occur after transplantation.

Abstract
Transplantation is an established therapy for end-stage diseases of the kidney, endocrine pancreas, heart, liver, lung, intestines and for many hematological disorders. Current immunosuppressive regimens with glucocorticoids and calcineurin inhibitors produce excellent patient and graft survival rates. This has resulted in both increases in transplant numbers and an increased recognition of previously neglected long-term complications of transplantation such as fractures and osteoporosis. Both pretransplantation bone disease and immunosuppressive therapy result in rapid bone loss and increased fracture rates. Patients are particularly at risk early after transplantation. The bone health of candidates for organ transplantation should be assessed with bone densitometry of the hip and spine. Spinal x-rays should be performed to diagnose prevalent fractures. Any secondary causes of osteoporosis should be identified and treated. Vitamin D deficiency should be corrected with vitamin D doses selected to achieve a serum 25-hydroxyvitamin D concentration of at least 20 ng/ml. All patients should receive calcium. Patients with kidney failure should be evaluated and treated for chronic kidney disease-mineral and bone disorder, including renal osteodystrophy. Secondary hyperparathyroidism, in particular, should be treated. Treatment is indicated in the immediate posttransplantation period irrespective of bone mineral density because further rapid bone loss will occur in the first several months after transplantation. Long-term organ transplant recipients should also have bone mass measurement and treatment of osteoporosis. Oral and iv bisphosphonates are the most promising approach for the management of transplantation osteoporosis. Active vitamin D metabolites may have additional benefits in reducing hyperparathyroidism, particularly after kidney transplantation.

Abstract
Bone disease is common in recipients of kidney, liver, heart, and lung transplants and results in fractures in 20-40% of patients, a rate much higher than expected for age. Fractures occur because of the presence of bone disease as well as other factors such as neuropathy, poor balance, inactivity, and low body or muscle mass. Major contributors to bone disease include both preexisting bone disease and bone loss post transplant, which is greatest in the first 6-12 months when steroid doses are highest. Bone disease in kidney transplant recipients should be considered different from that which occurs in other solid organ transplant recipients for several reasons including the presence of renal osteodystrophy, which contributes to low bone mineral density in these patients; the location of fractures (more common in the legs and feet in these patients than in spine and hips as in other solid organ recipients); and the potential danger in using bisphosphonate therapy, which may cause more harm than good in kidney transplant recipients with low bone turnover. Evaluation in all patients should preferably occur in the pretransplant period or early post transplant and should include assessment of fracture risk as well as metabolic factors that can contribute to bone disease. Bone mineral density measurement is recommended in all patients even if its predictive value for fracture risk in the transplant population is unproven. Management of bone disease should be directed toward decreasing fracture risk as well as improving bone density. Pharmacologic and nonpharmacologic treatment strategies are discussed in this review. Although there have been many studies describing a beneficial effect of bisphosphonates and vitamin D analogues on bone density, none have been powered to detect a decrease in fracture rate.

Abstract
BACKGROUND Patients with cystic fibrosis (CF) are at risk for early bone loss, and demonstrate increased risks for vertebral fractures and kyphosis. A multicenter, randomized, controlled trial was conducted to assess the efficacy, tolerability, and safety of therapy with oral alendronate (FOSAMAX; Merck; Whitehouse Station, NJ) in adults with CF and low bone mass. METHODS Participants received placebo or alendronate, 70 mg once weekly, for 12 months. All participants received 800 IU of vitamin D and 1,000 mg of calcium daily. Adults with confirmed CF with a bone mineral density (BMD) T score of < - 1.0 were eligible for inclusion. Participants who had undergone organ transplantation or had other reported contraindications were excluded from the study. The primary outcome measure was the mean (+/- SD) percentage change in lumbar spine BMD after 12 months. Secondary measures included the percentage change in total hip BMD, the number of new vertebral fractures (grade 1 or 2), and changes in quality of life. RESULTS A total of 56 participants were enrolled in the study (mean age, 29.1 +/- 8.78 years; 61% male). The absolute percentage changes in lumbar spine and total hip BMDs at follow-up were significantly higher in the alendronate therapy group (5.20 +/- 3.67% and 2.14 +/- 3.32%, respectively) than those in the control group (- 0.08 +/- 3.93% and - 1.3 +/- 2.70%, respectively; p < 0.001). At follow-up, two participants (both in the control group) had a new vertebral fracture (not significant), and there were no differences in quality of life or the number of adverse events (including serious and GI-related events). CONCLUSION Alendronate therapy was well tolerated and produced a significantly greater increase in BMD over 12 months compared with placebo.

Abstract
UNLABELLED A fracture risk assessment tool (FRAX) is developed based on the use of clinical risk factors with or without bone mineral density tests applied to the UK. INTRODUCTION The aim of this study was to apply an assessment tool for the prediction of fracture in men and women with the use of clinical risk factors (CRFs) for fracture with and without the use of femoral neck bone mineral density (BMD). The clinical risk factors, identified from previous meta-analyses, comprised body mass index (BMI, as a continuous variable), a prior history of fracture, a parental history of hip fracture, use of oral glucocorticoids, rheumatoid arthritis and other secondary causes of osteoporosis, current smoking, and alcohol intake 3 or more units daily. METHODS Four models were constructed to compute fracture probabilities based on the epidemiology of fracture in the UK. The models comprised the ten-year probability of hip fracture, with and without femoral neck BMD, and the ten-year probability of a major osteoporotic fracture, with and without BMD. For each model fracture and death hazards were computed as continuous functions. RESULTS Each clinical risk factor contributed to fracture probability. In the absence of BMD, hip fracture probability in women with a fixed BMI (25 kg/m(2)) ranged from 0.2% at the age of 50 years for women without CRF's to 22% at the age of 80 years with a parental history of hip fracture (approximately 100-fold range). In men, the probabilities were lower, as was the range (0.1 to 11% in the examples above). For a major osteoporotic fracture the probabilities ranged from 3.5% to 31% in women, and from 2.8% to 15% in men in the example above. The presence of one or more risk factors increased probabilities in an incremental manner. The differences in probabilities between men and women were comparable at any given T-score and age, except in the elderly where probabilities were higher in women than in men due to the higher mortality of the latter. CONCLUSION The models provide a framework which enhances the assessment of fracture risk in both men and women by the integration of clinical risk factors alone and/or in combination with BMD.

Abstract
UNLABELLED To assess the risk of fractures after a solid organ transplantation among diabetic versus nondiabetic patients, we conducted a nested case-control study. Pretransplant diabetes was associated with a 2-fold increase in post-transplant fractures. INTRODUCTION Diabetes has been associated with osteoporosis in the general population. However, among patients receiving solid organ transplantation, the association between pretransplant diabetes and post-transplant fractures is not clear, although both diabetes and fractures are prevalent among this patient population. We aimed to determine whether pretransplant diabetes increases the risk of fractures among patients receiving solid organ transplantation. MATERIALS AND METHODS We conducted a nested case-control study in a cohort of subjects 18 years and older, enrolled in the Quebec Drug Insurance Plan, who received a first solid organ transplantation between January 1986 and December 2005. Cases had sustained a fracture between the date of discharge from the hospitalization for solid organ transplantation and the end of the study period. All remaining patients were eligible controls. The fracture date was the case index date. Cases were matched to up to four controls on the type of organ transplanted and the date of transplantation. The index date of a control patient was that of his/her matched case. Crude and adjusted ORs were obtained with univariate and multivariate conditional logistic regression models. RESULTS The study included 238 cases and 873 controls. Pretransplant diabetes was present in 30% of the cases and 22% of the controls (crude OR: 2.16; 95% CI: 1.7-2.8). After adjusting for age, sex, previous fractures, past hyperthyroidism, hospitalization duration, use of narcotics, benzodiazepines, antidepressants, loop diuretics, thiazide diuretics, glucocorticoids, immunosuppressants, estrogens, bisphosphonates, calcium, vitamin D, and calcitonin, pretransplantation diabetes remained a significant risk factor for fractures (adjusted OR: 1.94; 95% CI: 1.5-2.6). Use of narcotics (OR: 3.0; 95% CI: 2.0-4.4) and antidepressants (OR: 1.9; 95% CI: 1.2-3.1) in the month preceding the index date and use of loop diuretics in the year preceding the index date (OR: 1.4; 95% CI: 1.1-1.9) were also associated with increased risks of fractures. CONCLUSIONS Pretransplant diabetes seemed to significantly increase post-transplant fractures among adults receiving solid organ transplantation. Pretransplant fracture prophylaxis should be considered in these patients.

Abstract
Osteoporosis is prevalent in transplant recipients and is related to pre- and post-transplantation factors. Low bone density and fractures may antedate transplantation, related to traditional risk factors for osteoporosis, effects of chronic illness, and end-stage organ failure and its therapy, on the skeleton. Bone loss after transplantation is related to adverse effects of immunosuppressive drugs (glucocorticoids and calcineurin inhibitors) on bone remodeling. Newer immunosuppressive medications may permit lower doses of glucocorticoids and may be associated with decreased bone loss and fractures. Bisphosphonates are currently the most effective agents for the prevention and treatment of post-transplantation osteoporosis.

Abstract
BACKGROUND Although new approaches to the treatment of patients with cystic fibrosis (CF) are significantly prolonging their lives, most patients will eventually develop respiratory failure due to progressive bronchiectasis caused by chronic lung infection and inflammation and die from to respiratory failure. We examined our center's (University of Wisconsin Hospital and Clinics) experience with lung transplantation for patients with CF and reviewed the literature to examine current and evolving approaches to transplantation for this indication. METHODS We reviewed all published literature pertaining to lung transplantation for CF through 2006, and we reviewed all aspects of transplantation for patients with CF at our institution from 1994 to 2005. RESULTS Major complications following lung transplantation include acute rejection, bacterial infection, and bronchiolitis obliterans. Five-year survival at UWHC (Kaplan-Meier) is 67%, and survival was not adversely affected by transplanting patients receiving mechanical ventilation. The major cause of death for transplant recipients was bronchiolitis obliterans syndrome (BOS). CONCLUSIONS Lung transplantation for CF is associated with acceptable survival rates and can improve quality of life. Lung transplant should be offered to all patients with advanced CF lung disease if they meet currently accepted inclusion and exclusion criteria.

Abstract
In the past two decades, there has been a rapid increase in the number of organ transplanted worldwide, including Brazil, along with an improvement in survival and quality of life of the transplant recipients. Osteoporosis and a high incidence of fragility fractures have emerged as a complication of organ transplantation. Many factors contribute to the pathogenesis of osteoporosis following organ transplantation. In addition, most patients have some form of bone disease prior to transplantation, which is usually related to adverse effects of end-stage organ failure on the skeleton. This chapter reviews the mechanisms of bone loss that occur both in the early and late post-transplant periods, as well as the features specific to bone loss after kidney, lung, liver, cardiac and bone marrow transplantation. Prevention and treatment for osteoporosis should be instituted prior and in the early and late phase after transplantation, and will also be addressed in this article.

Abstract
Organ transplantation has undeniably increased the longevity and quality of life of patients with end-stage organ failure. Its has, however, introduced the skeletal complications of (1) fragility fractures and decreased bone density due to pretransplant bone loss and immunosuppressive therapy, and (2) avascular necrosis leading to subchondral fracture and secondary osteoarthritis. This article reviews these two skeletal complications of solid-organ transplantation that lead to structural failure of bone and result in significant morbidity and reduced quality of life.

Abstract
Lung transplantation in children has been performed since the early 1990s. The indications are cystic fibrosis, pulmonary vascular disease, and a variety of other pulmonary problems leading to death in small children. These other diseases include abnormalities in the metabolism of surfactant producing severe respiratory insufficiency in newborn infants. Many problems accompany these patients before transplantation and many problems are produced both by the transplant itself and immunosuppressant drugs which these children are obliged to take following transplantation. Nonetheless, lung transplantation offers the only real hope of survival in many instances. The long-term results have been somewhat discouraging with a 5-year survival of approximately 50%. The major causes of mortality late following lung transplantation are bronchiolitis obliterans, infections, and malignancy. The development of newer immunosuppressant drugs may offer hope for better results in the future.

Abstract
INTRODUCTION Osteoporosis is a common condition in patients with end-stage lung disease, but little attention has been given to bone disease in patients with primary pulmonary hypertension (PPH). The purposes of this study were as follows: (1) to determine the prevalence of osteoporosis in patients with severe PPH before lung transplantation, (2) to investigate whether generally accepted risk factors for osteoporosis would play a role in this special group of patients, and (3) to determine whether there is an association between functional parameters and pretransplantion bone mass. DESIGN A retrospective analysis of 18 consecutive patients with PPH accepted for lung transplantation at the University Hospital of Zurich. MEASUREMENTS AND RESULTS Decreased bone mineral density (BMD) [T score <- 1.0] was found in 11 of 18 patients (61%) at the femoral neck (FN) and 13 of 18 patients (72%) at the lumbar spine (LS). We did not find a significant difference of BMD in a gender- or age-specific manner. Body mass index (BMI) correlated significantly with BMD and T score at the FN and WT. Pulmonary vascular resistance (PVR) was notably linked with BMD at the FN. We found a positive association between walking distance in the 12-min walking test and BMD at the FN and WT. CONCLUSIONS Low bone density is a very frequent condition in patients with severe PPH. In contrast to the general population, in our study group neither age nor female gender were significantly associated with lower bone mass. Body weight and BMI were highly coupled with BMD. Among the functional parameters, walking distance and PVR were correlated to BMD at the FN. Considering that patients with PPH may have an improved life expectancy in the future, the early diagnosis, prevention, and treatment of osteoporosis should receive high priority.

Abstract
STUDY OBJECTIVES There are no studies focused on skeletal status in patients with diffuse parenchymal lung disease (DPLD). We hypothesized that patients with DPLD referred for lung transplantation would have a high prevalence of osteoporosis related to corticosteroid use or reduced pulmonary function and exercise capacity. DESIGN Retrospective cohort study. SETTING Tertiary care center. PATIENTS Eighty-six patients with DPLD referred to our center for lung transplantation evaluation between March 1999 and April 2004. MEASUREMENTS AND RESULTS Dual-energy X-ray absorptiometry was used to measure bone mineral density (BMD) at the lumbar spine, femoral neck, total hip, and radius at the time of referral. Criteria developed by the World Health Organization were used to define osteopenia and osteoporosis. Fifty-five patients (64%) had usual interstitial pneumonia-pattern lung disease, 14 patients (16%) had nonspecific interstitial pneumonia-pattern lung disease, and 17 patients (20%) had other forms of DPLD. Sixty-four patients (74%) were receiving corticosteroids, and 43 patients (50%) were receiving preventive therapy for osteoporosis. Eleven patients (13%; 95% confidence interval [CI], 7 to 22%) met criteria for osteoporosis at any site, and 49 patients (57%; 95% CI, 46 to 68%) had osteopenia. Lower body mass index (BMI) [adjusted odds ratio (OR), 1.3; 95% CI, 1.1 to 1.6; p = 0.007] and Hispanic ethnicity (adjusted OR, 9.7; 95% CI, 1.8 to 52; p = 0.008) were independently associated with an increased risk of osteoporosis. Linear regression analysis confirmed that BMD at the femoral neck and hip was directly associated with BMI (p < 0.002). These findings were not affected by adjustment for the use of corticosteroids or osteoporosis prophylaxis, pulmonary function, or exercise performance. CONCLUSIONS Reduced BMD was common in patients with DPLD who were referred for lung transplantation. Lower BMD was associated with lower BMI, whereas there was no association with other clinical factors in our cohort. Hispanic patients with DPLD had a higher risk of osteoporosis than non-Hispanic patients, independent of other variables. Given their increased risk of bone loss, patients with DPLD should undergo screening for osteoporosis and receive prophylaxis and treatment according to published guidelines.

Abstract
Although many lung allograft recipients achieve long-term survival, there is a lack of published data regarding these patients' functional status and quality of life (QoL). We evaluated all 10-year survivors at our institution and, utilizing the SF-36 questionnaire, compared their QoL to population normative and chronic illness data. Twenty-eight (29%) of 96 patients survived > or =10 years following 11 single, 6 bilateral and 11 heart-lung procedures. At the most recent evaluation, median FEV(1) in single and double lung recipients was predicted to be 54% and 74%, respectively. Five (18%) patients had BOS score 0, 13 (46%) BOS 1, 5 (18%) BOS 2 and 5 (18%) BOS 3 and median time to BOS was 7 years. Four (14%) patients required renal replacement therapy. Three patients (11%) developed symptomatic osteoporosis, 2 (7%) post-transplant lymphoma and 1 (4%) an ischaemic stroke. Scores for physical function, role-physical/emotional and general health, but not mental health and bodily pain, were significantly lower compared to normative and chronic illness data. Energy and social-function scores were significantly lower than normative data alone. Long-term survival after lung transplantation is characterized by an absence or delayed development of BOS, low iatrogenic morbidity and preserved mental, but reduced physical health status.

Abstract
Steroidal glucocorticoids are commonly used due to their powerful antiinflammatory activity. However, despite their excellent efficacy, severe side effects frequently limit the use of these drugs. The search for novel glucocorticoids with reduced side effects has been intensified by the discovery of new molecular details regarding the function of the glucocorticoid receptor. These new insights may pave the way for novel, safer therapies that retain the efficacy of currently prescribed steroids.

Abstract
We describe a constellation of bone diseases characterized by the common feature of acute, rapid, and severe bone loss accompanied by dramatic fracture rates. These disorders are poorly recognized, resulting mainly from systemic diseases, frailty, immobilization, and immunosuppressive drugs, such as glucocorticoids and the calcineurin inhibitors. The opportunity to prevent or treat fractures is commonly missed because they are often not detected. Ideally, patients need to be identified early and preventative therapy initiated promptly to avoid the rapid bone loss and fractures. The most effective therapy at present seems to be the bisphosphonates, particularly when bone resorption is predominant. However, more severe forms of bone loss that result from an osteoblastic defect and reduced bone formation may benefit potentially more from newer anabolic agents, such as recombinant human parathyroid hormone (rhPTH).

Abstract
Since international recommendations for lung transplant recipients were made in 1998, newer tools for predicting mortality in patients who have end-stage lung disease have been investigated. This article reviews studies for predicting mortality in obstructive, restrictive, pulmonary vascular, and suppurative/bronchiectatic lung disease. Newer considerations for alternative treatments, postoperative risks, and contraindications are also examined. The article aims to provide more accurate data for selecting patients who will benefit from lung transplantation.

Abstract
Osteoporosis remains a serious potential complication of liver transplantation, although its incidence may be significantly reduced by the use of lower doses of glucocorticoids. Additional factors likely to contribute to its pathogenesis include other immunosuppressive agents, particularly cyclosporin A and FK506, vitamin D insufficiency, secondary hyperparathyroidism, hypogonadism and pre-existing bone disease. Bone density assessment and spinal X-rays should be performed before transplantation to assess subsequent fracture risk and vitamin D and gonadal status assessed. Measures should be taken to optimise bone health prior to transplantation; in those with low bone mineral density and/or previous fragility fracture, prophylaxis against bone loss after transplantation should be considered. Although anti-fracture efficacy has not been established for any agent there is evidence, mainly in patients undergoing other forms of solid organ transplantation, that repeated infusions of pamidronate may be effective in preventing bone loss.

Abstract
Secondary causes of bone loss are not often considered in patients who are diagnosed as having osteoporosis. In some studies, 20% to 30% of postmenopausal women and more than 50% of men with osteoporosis have a secondary cause. There are numerous causes of secondary bone loss, including adverse effects of drug therapy, endocrine disorders, eating disorders, immobilization, marrow-related disorders, disorders of the gastrointestinal or biliary tract, renal disease, and cancer. Patients who have undergone organ transplantation are also at increased risk for osteoporosis. In many cases, the adverse effects of osteoporosis are reversible with appropriate intervention. Because of the many treatment options that are now available for patients with osteoporosis and the tremendous advances that have been made in understanding the pathogenesis and diagnosis of the condition, it is important that medical disorders are recognized and appropriate interventions are undertaken. This article provides the framework for understanding causes of bone loss and approaches to their management.

Abstract
Osteoporosis is a leading cause of pretransplant and posttransplant morbidity. The need for early detection by measuring bone mineral density, even before transplant, must be emphasized. Preventive measures are not comparable. The use of calcium and vitamin D supplements, although recommended, is inadequate for the prevention of bone loss and complications such as vertebral fractures. Bisphosphonates have been shown to attenuate the bone loss and reduce fractures associated with steroid-induced osteoporosis. Small studies in transplant recipients suggest similar results. Other preventive measures such as hormone replacement therapy are also helpful. There are limited data on the administration of nasal calcitonin in transplant recipients.

Abstract
Due to progress in lung transplantation, post-transplantation osteoporosis becomes an important problem. We determined bone mineral density (BMD) in 74 lung transplantation candidates, among them 24 patients with cysticfibrosis, 16 with chronic obstructive pulmonary disease, 14 with pulmonary fibrosis, and 11 with pulmonary hypertension. The mean T score (+/- SD) was -2.6 +/- 1.3 at femoral neck (FN), -2.2 +/- 1.6 at Ward's triangle (WT) and -2.3 +/- 1.5 at lumbar spine (LS). Osteoporosis was found in 61% of the patients at FN, 45% at WT and 50% at LS. Patients with different underlying lung diseases were similarly affected, not only those with cystic fibrosis but also others, including patients with pulmonary hypertension. No association was found between BMD and age, gender, menstrual condition in women and testosterone level in men. A negative correlation was found between chronic glucocorticoid use and T scores. Body mass index correlated positively (p < 0.01) with T scores at any site and the correlation was also significant for the 2 largest subgroups. Loss of lung function (FEV1) also was associated with lower T scores. No correlation was found between BMD and biochemical indices of bone turnover. Multivariate analysis revealed BMI and glucocorticoid use as independent risk factors. We conclude that osteoporosis is a very common condition in patients with end-stage pulmonary disease, independent of the underlying diagnosis. In view of additional bone loss under immunosuppressive treatment after lung transplantation, early diagnosis and prevention of osteoporosis in the pretransplant period should receive high priority.
