This population-based case-control analysis investigated the association between osteoporosis and prior urinary calculus (UC) in Taiwan. We succeeded in detecting an association between osteoporosis and prior UC (adjusted odds ratio = 1.66). This association was consistent and significant regardless of stone location. UC has been demonstrated to be a risk factor for osteoporotic fractures, but no studies to date have directly investigated the association between UC and osteoporosis. This case-control analysis aimed to investigate the association of osteoporosis with prior UC using a population-based dataset in Taiwan. We first identified 39,840 cases ≥40 years who received their first-time diagnosis of osteoporosis between 2002 and 2009 and then randomly selected 79,680 controls. We used conditional logistic regression analyses to compute the odds ratio (OR) and the corresponding 95 % confidence interval (CI) for having been previously diagnosed with UC between cases and controls. The OR of having been previously diagnosed with UC for patients with osteoporosis was 1.66 (95 % CI = 1.59-1.73) when compared to controls after adjusting for geographic location, urbanization level, type I diabetes mellitus, coronary heart disease, hyperlipidemia, rheumatoid arthritis, stroke, renal disease, Parkinson's disease, hyperthyroidism, chronic hepatopathy, Cushing's syndrome, malabsorption, gastrectomy, obesity, and alcohol abuse/alcohol dependence syndrome. The results consistently showed that osteoporosis was significantly associated with a previous diagnosis of UC regardless of stone location; the adjusted ORs of prior kidney calculus, ureter calculus, bladder calculus, and unspecified calculus when compared to controls were 1.71 (95 % CI = 1.61-1.81), 1.60 (95 % CI = 1.47-1.74), 1.59 (95 % CI = 1.23-2.04), and 1.69 (95 % CI = 1.59-1.80), respectively. This study succeeded in detecting an association between osteoporosis and prior UC. In addition

Reduction of bone mineral density (BMD) is a known and established phenomenon in chronic obstructive pulmonary disease (COPD). However, there have been no data regarding osteoporosis/osteopenia in COPD patients in India. To look for the degree and frequency of osteoporosis/osteopenia in our OPD patients being diagnosed as COPD. Thirty-seven randomly selected patients with COPD were assessed for BMD with commercially available ultrasound bone densitometer (HOLOGIC SAHARA) in a pulmonary OPD. Some cofactors for reduced BMD were also noted. Out of the 37 COPD (all belonging to the GOLD III/IV category) patients studied, the BMD was found to be normal in 10 (27%) patients, while 27 (73%) patients were found to have osteopenia/osteoporosis [19 (51.35%) and 8 (21.62%) patients having osteopenia and osteoporosis, respectively]. Frequency of osteoporosis and osteopenia was found to be very high (73%) in our population of advanced COPD. The data suggest a need for further in-depth study regarding the issue.

Osteoporosis in rheumatic diseases is a very well-known complication. Systemic inflammation results in both generalized and localized bone loss and erosions. Recently, increased knowledge of inflammatory process in rheumatic diseases has resulted in the development of potent inhibitors of the cytokines, the biologic DMARDs. These treatments reduce systemic inflammation and have some effect on the generalized and localized bone loss. Progression of bone erosion was slowed by TNF, IL-6 and IL-1 inhibitors, a JAK inhibitor, a CTLA4 agonist, and rituximab. Effects on bone mineral density varied between the biological DMARDs. Medications that are approved for the treatment of osteoporosis have been evaluated to prevent bone loss in rheumatic disease patients, including denosumab, cathepsin K, bisphosphonates, anti-sclerostin antibodies and parathyroid hormone (hPTH 1-34), and have some efficacy in both the prevention of systemic bone loss and reducing localized bone erosions. This article reviews the effects of biologic DMARDs on bone mass and erosions in patients with rheumatic diseases and trials of anti-osteoporotic medications in animal models and patients with rheumatic diseases.

Inflammation in renal atherosclerotic disease.

Udani, Suneel M; Dieter, Robert S

2008-07-01

The study of renal atherosclerotic disease has conventionally focused on the diagnosis and management of renal artery stenosis. With the increased understanding of atherosclerosis as a systemic inflammatory process, there has been increased interest in vascular biology at the microvasculature level. While different organ beds share some features, the inflammation and injury in the microvasculature of the kidney has unique elements as well. Understanding of the pathogenesis yields a better understanding of the clinical manifestations of renal atherosclerotic disease, which can be very subtle. Furthermore, identifying the molecular mechanisms responsible for the progression of kidney damage can also direct clinicians and scientists toward targeted therapies. Existing therapies used to treat atherosclerotic disease in other vascular beds may also play a role in the treatment of renal atherosclerotic disease.

Synthetic human calcitonin was used in the treatment of 26 patients over a period of 1-14 months. 17 patients had Paget's disease of the bone, 6 postmenopausal osteoporosis and 3 Sudeck's syndrome. Subjective improvement (reduction of pain, improvement of mobility) was found in 15 patients with Paget's disease, in 4 females with postmenopausal osteoporosis and in all 3 patients with Sudeck's syndrome. Radiographic improvement of bone changes developed only very slowly. These results were confirmed by diminution of the exchangeable calcium pool indicating reduction of rates of osseous degradation. Calcitonin tolerance was acceptable. Transitory nausea and occasional vomiting occurred in 3 patients.

Transient regional osteoporosis

Full Text Available Transient osteoporosis of the hip and regional migratory osteoporosis are uncommon and probably underdiagnosed bone diseases characterized by pain and functional limitation mainly affecting weight-bearing joints of the lower limbs. These conditions are usually self-limiting and symptoms tend to abate within a few months without sequelae. Routine laboratory investigations are unremarkable. Middle aged men and women during the last months of pregnancy or in the immediate post-partum period are principally affected. Osteopenia with preservation of articular space and transitory edema of the bone marrow provided by magnetic resonance imaging are common to these two conditions, so they are also known by the term regional transitory osteoporosis. The appearance of bone marrow edema is not specific to regional transitory osteoporosis but can be observed in several diseases, i.e. trauma, reflex sympathetic dystrophy, avascular osteonecrosis, infections, tumors from which it must be differentiated. The etiology of this condition is unknown. Pathogenesis is still debated in particular the relationship with reflex sympathetic dystrophy, with which regional transitory osteoporosis is often identified. The purpose of the present review is to remark on the relationship between transient osteoporosis of the hip and regional migratory osteoporosis with particular attention to the bone marrow edema pattern and relative differential diagnosis.

Purinergic Signalling in Inflammatory Renal Disease

Directory of Open Access Journals (Sweden)

Nishkantha eArulkumaran

2013-07-01

Full Text Available Extracellular purines have a role in renal physiology and adaption to inflammation. However, inflammatory renal disease may be mediated by extracellular purines, resulting in renal injury. The role of purinergic signalling is dependent on the concentrations of extracellular purines. Low basal levels of purines are important in normal homeostasis and growth. Concentrations of extracellular purines are significantly elevated during inflammation and mediate either an adaptive role or propagate local inflammation. Adenosine signalling mediates alterations in regional renal blood flow by regulation of the renal microcirculation, tubulo-glomerular feedback, and tubular transport of sodium and water. Increased extracellular ATP and renal P2 receptor-mediated inflammation are associated with various renal diseases, including hypertension, diabetic nephropathy, and glomerulonephritis. Experimental data suggests P2 receptor deficiency or receptor antagonism is associated with amelioration of antibody-mediated nephritis, suggesting a pathogenic (rather than adaptive role of purinergic signalling. We discuss the role of extracellular nucleotides in adaptation to ischaemic renal injury and in the pathogenesis of inflammatory renal disease.

2013-01-01

There are differences in renal anatomy and physiology between rabbits and other domestic species. Neurogenic renal ischemia occurs readily. Reversible prerenal azotemia may be seen in conjunction with gut stasis. Potentially fatal acute renal failure may be due to structural kidney damage or post-renal disease. Chronic renal failure is often associated with encephalitozoonosis. Affected rabbits cannot vomit and often eat well. Weight loss, lethargy, and cachexia are common clinical signs. Polydypsia/polyuria may be present. Derangements in calcium and phosphorus metabolism are features of renal disease. Radiography is always indicated. Urolithiasis, osteosclerosis, aortic and renal calcification are easily seen on radiographs. Copyright © 2013 Elsevier Inc. All rights reserved.

Celiac disease, an inflammatory disease of small bowel caused by sensitivity to dietary gluten and related protein, affects approximately 0.5-1% of the population in the Western world. Extra-intestinal symptoms and associated diseases are increasingly recognized including diabetes mellitus type 1, thyroid disease, dermatitis herpetiformis and ataxia. There have also been a number of reports of various types of renal involvement in patients with celiac disease including diabetes nephropathy, IgA nephropathy, membranous nephropathy, membranoproliferative glomerulonephritis, nephrotic syndrome related to malabsorption, oxalate nephropathy, and associations of celiac disease with chronic kidney disease and end-stage kidney disease. This review aims to present the current literature on possible pathologic mechanisms underlying renal disease in patients with celiac disease.

Osteoporosis affects over 200 million people worldwide at a high cost to healthcare systems. Although guidelines on assessing and managing osteoporosis are available, many patients are not receiving appropriate diagnostic testing or treatment. Findings from a systematic review of osteoporosis interventions, a series of mixed-methods studies, and advice from experts in osteoporosis and human-factors engineering were used collectively to develop a multicomponent tool (targeted to family physicians and patients at risk for osteoporosis) that may support clinical decision making in osteoporosis disease management at the point of care. A three-phased approach will be used to evaluate the osteoporosis tool. In phase 1, the tool will be implemented in three family practices. It will involve ensuring optimal functioning of the tool while minimizing disruption to usual practice. In phase 2, the tool will be pilot tested in a quasi-experimental interrupted time series (ITS) design to determine if it can improve osteoporosis disease management at the point of care. Phase 3 will involve conducting a qualitative postintervention follow-up study to better understand participants' experiences and perceived utility of the tool and readiness to adopt the tool at the point of care. The osteoporosis tool has the potential to make several contributions to the development and evaluation of complex, chronic disease interventions, such as the inclusion of an implementation strategy prior to conducting an evaluation study. Anticipated benefits of the tool may be to increase awareness for patients about osteoporosis and its associated risks and provide an opportunity to discuss a management plan with their physician, which may all facilitate patient self-management.

There are conflicting reports about the renal involvement in Behcet's disease (BD). In this study we aimed to study the frequency and type of renal involvement in a group of patients with BD in Azerbaijan province that is one of the prevalent areas of BD in Iran. All cases of BD were prospectively followed between June 2004 and January 2007, and evaluated for renal dys-function (serum creatinine > 1.7 mg/dL), glomerular hematuria and proteinuria. Those patients with proteinuria > 500 mg/day and serum creatinine level > 2 mg/dL, underwent renal biopsy. From a total number of 100 patients, six patients (6%) had obvious renal involvements. Four patients had glomerular hematuria and proteinuria. Renal biopsy in two of them revealed measangial proliferative glumerulonephritis with IgA deposit in one of them and membranoproliferative glumerolonephritis in another one. Two remaining patients had serum creatinine > 2 mg/dL without any hematuria or proteinuria. Serologic study for viral agents and collagen vascular disease were negative in all patients with renal involvements. In conclusion, renal involvement in BD is not infrequent, although in most cases it is mild in nature and may be missed. (author)

Several diseases and medications are known to induce secondary osteoporosis. Among them, same situations are related to gynecological field. They include Turner's syndrome, anorexia nervosa, ovarian dysfunction, oophorectomy, GnRH agonist therapy, and osteoporosis associated with pregnancy. We briefly describe these secondary osteoporosis in this article as follows. Several studies have found osteoporosis to be a common complication of Turner's syndrome and hormone replacement therapy has been used as a possible management; in anorexic patient, low body weight, prolonged amenorrhea, early onset of anorexia nervosa, and hypercortisolism have been reported to be risks for bone demineralization; since oophorectomy which is a common intervention in gynecology leads osteoporosis, it is important to prevent osteoporosis caused by surgery as well as postmenopausal osteoporosis; GnRH agonist, which induces estrogen deficient state and affect bone mass, is commonly used as a management for endometriosis and leiomyoma of uterus; associated with pregnancy, post-pregnancy spinal osteoporosis and transient osteoporosis of the hip are clinically considered to be important and heparin therapy and magnesium sulfate therapy are commonly employed during pregnancy, affecting calcium homeostasis.

The aim of the present study was to determine the association between osteoporosis and periodontal disease among postmenopausal Indian women. A cross-sectional comparative study was conducted among postmenopausal women aged 45-65 years attending various hospitals in Bangalore, India. The examination was performed using the plaque index, gingival index, modified sulcus bleeding index, and community periodontal index. The women then underwent a bone mineral density (BMD) test using an ultrasonometer. Based on the BMD scores, participants were divided into osteoporotic and non-osteoporotic groups. For the statistical analysis, χ 2 -test, Student's t-test, and multiple regression analysis were applied. The mean plaque, gingival, and bleeding scores were significantly higher among osteoporotic women (1.83 ± 0.47, 1.73 ± 0.49, 1.82 ± 0.52) compared to the non-osteoporotic women (1.31 ± 0.40, 1.09 ± 0.52, 1.25 ± 0.50). The mean number of sextants affected for codes 3 and 4 of the community periodontal index and codes 1, 2, and 3 of loss of attachment were significantly higher among osteoporotic group compared to the non-osteoporotic group. Multiple logistic regression tests confirmed the statistically-significant association between osteoporosis and menopause duration, loss of attachment, bleeding, and gingivitis scores. Skeletal BMD is related to clinical attachment loss, bleeding, and gingivitis, which suggests that there is an association between osteoporosis and periodontal diseases. © 2016 John Wiley & Sons Australia, Ltd.

"Osteoporosis and orthopods" incidences of osteoporosis in distal radius fracture from low energy trauma.

Fracture of the distal radius from low energy trauma is a common presentation to orthopaedic trauma services. This fragility type fracture is associated with underlying osteoporosis. Osteoporosis is a \\'silent disease\\' where fragility fracture is a common presentation. Orthopaedic surgeons may be the only physician that these patients encounter. We found a high percentage of female patients who sustained a fragility fracture of the distal radius have an underlying osteoporosis. Further management of osteoporosis is important to prevent future fragility fractures.

Several issues regarding evaluation of renal injury and renal insufficiency in patients with liver disease

Directory of Open Access Journals (Sweden)

HAO Kunyan

2016-07-01

Full Text Available In patients with liver disease such as viral hepatitis and liver cirrhosis, renal injury and renal insufficiency can be generally classified as acute kidney injury (AKI, chronic kidney disease, and acute-on-chronic nephropathy. AKI can be classified as stage 1 (risk stage, stage 2 (injury stage, and stage 3 (failure stage. Traditionally hepatorenal syndrome is classified as types Ⅰ and Ⅱ, and in recent years, type Ⅲ hepatorenal syndrome with organic renal injury has been proposed. Hepatorenal disorder(HRD is used to describe any renal disease which occurs in patients with liver cirrhosis. At present, sensitive and accurate biochemical parameters used to evaluate renal function in patients with liver disease in clinical practice include estimated glomerular filtration rate, increase in serum creatinine within unit time, and serum cystatin C level, and urinary microalbumin level also plays an important role in the early diagnosis of nephropathy. Causes of liver disease, severity, complications including infection, nutritional status, therapeutic drugs, and underlying nephropathy may be associated with renal injury and renal insufficiency in patients with liver disease and should be differentiated.

Osteoporosis and Periodontitis.

Science.gov (United States)

Wang, Chin-Wei Jeff; McCauley, Laurie K

2016-12-01

Osteoporosis and periodontitis are both diseases characterized by bone resorption. Osteoporosis features systemic degenerative bone loss that leads to loss of skeletal cancellous microstructure and subsequent fracture, whereas periodontitis involves local inflammatory bone loss, following an infectious breach of the alveolar cortical bone, and it may result in tooth loss. Most cross-sectional studies have confirmed the association of osteoporosis and periodontitis primarily on radiographic measurements and to a lesser degree on clinical parameters. Multiple shared risk factors include age, genetics, hormonal change, smoking, as well as calcium and vitamin D deficiency. Both diseases could also be risk factors for each other and have a mutual impact that requires concomitant management. Suggested mechanisms underlying the linkage are disruption of the homeostasis concerning bone remodeling, hormonal balance, and inflammation resolution. A mutual interventional approach is emerging with complex treatment interactions. Prevention and management of both diseases require interdisciplinary approaches and warrants future well-controlled longitudinal and interventional studies for evidence-based clinical guidelines.

surfaces, with the net result of bone loss. Despite these findings, the occurrence of pathological fractures in patients with hyperthyroidism is relatively low, and probably due to the fact that deficiencies in bone mass may be reversed by treatment of the thyroid disease. Most, but not all, studies on insulin-dependent diabetes mellitus (IDDM) report an association with osteopenia. In IDDM, the extent of bone loss is usually slight, which helps explain the discrepancy between the frequency of decreased bone mineral density, and the frequency of osteoporotic fractures in long-standing diabetes. Contradictory results have been obtained in non-insulin-dependent diabetes mellitus (NIDDM) patients. Increased rates of bone loss at the radius and lumbar spine were demonstrated either in patients with two-thirds gastric resection and Billroth II reconstruction, or in those with one-third resection and Billroth I anastomosis, and the metabolic bone disease following gastrectomy may consist also of osteomalacia or mixed pattern of osteoporosis-osteomalacia, with secondary hyperparathyroidism. Miscellaneous causes of secondary osteoporosis are also immobilization, pregnancy and lactation, and alcohol abuse.

Renal cystic disease includes a group of lesions with extremely diverse clinical, radiographic, and pathologic findings. The recent development of multiple imaging systems to study renal cystic disease has resulted in considerable interest in correlating the images obtained by different modalities with each other and with the underlying gross pathology. A thorough knowledge of the disturbed morphology and natural history of these diseases will lead to a better understanding of their appearance on radiologic imaging. This refresher course correlates disturbed morphology with appearances on diagnostic imaging, urography, US, angiography, CT, and MR imaging. The advantages and limitations of each imaging method are detailed. A practical classification emphasizing differential features is presented. The presentation is divided into two parts. In the first part typical and atypical cystic masses, including acquired cystic disease (from dialysis), Von Hippel-Lindau disease, and the cystic disease of tuberous sclerosis are discussed. In the second part, polycystic kidney disease (dominant and recessive), medullary cystic disease, medullary sponge kidney, multicycle-dysplastic kidney, renal sinus cysts (peripelvic), and pluricystic kidney disease are discussed

Chronic kidney disease (CKD) is a public Heath problem with increasing prevalence in Pakistan. Early identification of mild renal disease can delay its progression. Glomerular filtration rate (GFR) is the best overall index of renal function, but it is difficult to measure, so mostly clinicians rely on. serum creatinine (SCr) concentration which its own limitations. On the other hand 24 hours (h) urinary creatinine clearance (CICl) is a more sensitive marker of renal dysfunction. Presently SCr is being used in our clinical practice to screen the renal diseases which can miss mild renal dysfunctions, so this study was designed to calculate frequency of individuals having reduced GFR as determined by CrCI having normal SCr levels.

Full Text Available Abstract Osteoporosis or osteopenia occurs in about 44 million Americans, resulting in 1.5 million fragility fractures per year. The consequences of these fractures include pain, disability, depression, loss of independence, and increased mortality. The burden to the healthcare system, in terms of cost and resources, is tremendous, with an estimated direct annual USA healthcare expenditure of about $17 billion. With longer life expectancy and the aging of the baby-boomer generation, the number of men and women with osteoporosis or low bone density is expected to rise to over 61 million by 2020. Osteoporosis is a silent disease that causes no symptoms until a fracture occurs. Any fragility fracture greatly increases the risk of future fractures. Most patients with osteoporosis are not being diagnosed or treated. Even those with previous fractures, who are at extremely high risk of future fractures, are often not being treated. It is preferable to diagnose osteoporosis by bone density testing of high risk individuals before the first fracture occurs. If osteoporosis or low bone density is identified, evaluation for contributing factors should be considered. Patients on long-term glucocorticoid therapy are at especially high risk for developing osteoporosis, and may sustain fractures at a lower bone density than those not taking glucocorticoids. All patients should be counseled on the importance of regular weight-bearing exercise and adequate daily intake of calcium and vitamin D. Exposure to medications that cause drowsiness or hypotension should be minimized. Non-pharmacologic therapy to reduce the non-skeletal risk factors for fracture should be considered. These include fall prevention through balance training and muscle strengthening, removal of fall hazards at home, and wearing hip protectors if the risk of falling remains high. Pharmacologic therapy can stabilize or increase bone density in most patients, and reduce fracture risk by about 50

The Receptor activator of nuclear factor-kappa B ligand (RANKL)/RANK/Osteoprotegerine (OPG) system has been proposed as essential for osteoclast biology and identified as key part in regulating the physiology and pathology of the skeletal system. The study of the RANKL/RANK/OPG system has increased the understanding of the mechanisms involved in the bone remodeling process, especially in postmenopausal osteoporosis and periodontal disease. Bisphosphonates have become the mainstay of the treatment and prevention of post-menopausal osteoporosis. They inhibit the formation and dissolution of calcium phosphate crystals in bone and also osteoclasts, thus reducing bone turnover.Current investigations relate osteoporosis with the appearance and progression of periodontal disease. Although the etiology of both is different, the bone loss present in both shares several characteristics. Thus, therapy used for osteoporosis can be considered of value in the treatment of periodontal disease. The aim of this study was to evaluate the levels of RANKL, OPG and their relationship in gingival crevicular fluid (GCF) in patients with periodontal disease and postmenopausal osteoporosis/ osteopenia in relation to consumption of bisphosphonates. We studied 66 periodontal active sites obtained from 17 post- menopausal women patients aged between 45-70 years old with osteoporosis/osteopenia and periodontal disease. GCF samples were collected using sterile filter paper strips. To determine the concentration of RANKL and OPG, a commercial ELISA assay was used. The values of RANKL, OPG and their ratio (RANKL/ OPG) were compared with Mann-Whitney U Test. The values of RANKL, OPG and their ratio obtained in patients with osteoporosis/osteopenia and periodontal disease with or without bisphosphonates treatment showed no differences. Bisphosphonates do not alter the concentration of RANKL and OPG and their ratio in the GCF of patients with osteoporosis/ osteopenia and periodontal disease

Cardiovascular diseases are major causes of mortality in chronic renal failure patients before and after renal transplantation. Among them, coronary disease presents a particular risk; however, risk predictors have been used to diagnose coronary heart disease. This study evaluated the frequency and importance of clinical predictors of coronary artery disease in chronic renal failure patients undergoing dialysis who were renal transplant candidates, and assessed a previously developed scoring system. Coronary angiographies conducted between March 2008 and April 2013 from 99 candidates for renal transplantation from two transplant centers in São Paulo state were analyzed for associations between significant coronary artery diseases (≥70% stenosis in one or more epicardial coronary arteries or ≥50% in the left main coronary artery) and clinical parameters. Univariate logistic regression analysis identified diabetes, angina, and/or previous infarction, clinical peripheral arterial disease and dyslipidemia as predictors of coronary artery disease. Multiple logistic regression analysis identified only diabetes and angina and/or previous infarction as independent predictors. The results corroborate previous studies demonstrating the importance of these factors when selecting patients for coronary angiography in clinical pretransplant evaluation.

Renal microvascular disease in an aging population: a reversible process?

Science.gov (United States)

Futrakul, Narisa; Futrakul, Prasit

2008-01-01

Renal microvascular disease and tubulointerstitial fibrosis are usually demonstrated in aging in humans and animals. It has recently been proposed that renal microvascular disease is the crucial determinant of tubulointerstitial disease or fibrosis. Enhanced circulating endothelial cell loss is a biomarker that reflects glomerular endothelial injury or renal microvascular disease, and fractional excretion of magnesium (FE Mg) is a sensitive biomarker that reflects an early stage of tubulointerstitial fibrosis. In aging in humans, both of these biomarkers are abnormally elevated. In addition, a glomerular endothelial dysfunction determined by altered hemodynamics associated with peritubular capillary flow reduction is substantiated. A correction of such hemodynamic alteration with vasodilators can effectively improve renal perfusion and restore renal function. Thus, anti-aging therapy can reverse the renal microvascular disease and dysfunction associated with the aging process.

Full Text Available The aging process results in profound anatomic and functional changes in a number of human body systems. Changes in kidney function with normal aging are the most dramatic of any human organ or organ system. These include anatomical, physiological, hemodynamic and immunological changes. Increased propensities of systemic diseases and exposure to poly-pharmacy of the aged group have an additive deleterious effect. The aforementioned changes have its implications on clinical presentations, management and prognosis of all renal diseases in elderly. Atypical presentation, more frequent and longer course are the characteristics of acute renal failure in this age group. Also, presentation of glomerular diseases, clinical course, prognosis, decision of performing a renal biopsy and use of immunosuppressive drugs in elderly specially those subgroup above 80 years of age are still a big challenges that needs a consensus and standardization.

Functional genomics in renal transplantation and chronic kidney disease

2010-01-01

For the past decade, the development of genomic technology has revolutionized modern biological research. Functional genomic analyses enable biologists to study genetic events on a genome wide scale. Examples of applications are gene discovery, biomarker determination, disease classification, and drug target identification. Global expression profiles performed with microarrays enable a better understanding of molecular signature of human disease, including acute and chronic kidney disease. About 10 % of the population in western industrialized nations suffers from chronic kidney disease (CKD). Treatment of end stage renal disease, the final stage of CKD is performed by either hemo- or peritoneal dialysis or renal transplantation. The preferred treatment is renal transplantation, because of the higher quality of life. But the pathophysiology of the disease on a molecular level is not well enough understood and early biomarkers for acute and chronic kidney disease are missing. In my studies I focused on genomics of allograft biopsies, prevention of delayed graft function after renal transplantation, anemia after renal transplantation, biocompatibility of hemodialysis membranes and peritoneal dialysis fluids and cardiovascular diseases and bone disorders in CKD patients. Gene expression profiles, pathway analysis and protein-protein interaction networks were used to elucidate the underlying pathophysiological mechanism of the disease or phenomena, identifying early biomarkers or predictors of disease state and potentially drug targets. In summery my PhD thesis represents the application of functional genomic analyses in chronic kidney disease and renal transplantation. The results provide a deeper view into the molecular and cellular mechanisms of kidney disease. Nevertheless, future multicenter collaborative studies, meta-analyses of existing data, incorporation of functional genomics into large-scale prospective clinical trials are needed and will give biomedical

The goal of this ongoing comprehensive osteoporosis disease management initiative is to provide the adult primary care physicians' (PCPs) offices with a program enabling them to systematically identify and manage their population for osteoporosis. For over six years, Hill Physicians Medical Group (Hill Physicians) has implemented multiple strategies to develop a best practice for identifying and treating members who were candidates for osteoporosis therapy. Numerous tools were used to support this disease management effort, including: evidence-based clinical practice guidelines, patient education sessions, the Simple Calculated Osteoporosis Risk Estimation (SCORE) questionnaire tool, member specific reports for PCPs, targeted member mailings, office-based Peripheral Instantaneous X-ray Imaging (PIXI) test and counseling, dual x-ray absorptiometry (DEXA) scan guidelines, and web-based Electronic Simple Calculated Osteoporosis Risk Estimation (eSCORE) questionnaire tools. Hill Physicians tabulated results for patients who completed 2649 SCORE tests, screened 978 patients with PIXI tests, and identified 338 osteopenic and 124 osteoporotic patients. The preliminary results of this unique six-year ongoing educational initiative are slow but promising. New physician offices express interest in participating and those offices that have participated in the program continue to screen for osteoporosis. Hill Physicians' message is consistent and is communicated to the physicians repeatedly in different ways in accordance with the principles of educational outreach. Physicians who have conducted the program have positive feedback from their patients and office staff and have begun to communicate their experience to their peers.

Osteoporosis represents a major and increasing public health problem with the aging of population. Major clinical consequences and economic burden of the disease are fractures. Many risk factors are associated with the fractures including low bone mass, hormonal disorders, personal and family history of fractures, low body weight, use of certain drugs (e.g. glucocorticoids), cigarette smoking, elevated intake of alchohol, low physical activity, insufficient level of vitamin D and low intake of calcium. This epidemiological review describes frequency, importance of risk factors and impact of osteoporosis and osteoporotic fractures. Objective measures of bone mineral density along with clinical assessment of risk factors can help identify patients who will benefit from prevention and intervention efforts and eventually reduce the morbidity and mortality associated with osteoporosis-related fractures.

In the last decade, there have been a number of action plans published to highlight the importance of preventing osteoporosis and related fractures. In the province of Ontario Canada, the Ministry of Health provided funding for the Ontario Osteoporosis Strategy. The goal is to reduce morbidity, mortality, and costs from osteoporosis and related fractures through an integrated and comprehensive approach aimed at health promotion and disease management. This paper describes the components of the Ontario Osteoporosis Strategy and progress on implementation efforts as of March 2009. There are five main components: health promotion; bone mineral density testing, access, and quality; postfracture care; professional education; and research and evaluation. Responsibility for implementation of the initiatives within the components is shared across a number of professional and patient organizations and academic teaching hospitals with osteoporosis researchers. The lessons learned from each phase of the development, implementation, and evaluation of the Ontario Osteoporosis Strategy provides a tremendous opportunity to inform other jurisdictions embarking on implementing similar large-scale bone health initiatives.

Essential hypertension, insulin resistance, heart failure, congestion, diuretic resistance, and functional renal disease are all characterized by excessive central sympathetic drive. The contribution of the kidney's somatic afferent nerves, as an underlying cause of elevated central sympathetic drive, and the consequences of excessive efferent sympathetic signals to the kidney itself, as well as other organs, identify the renal sympathetic nerves as a uniquely logical therapeutic target for diseases linked by excessive central sympathetic drive. Clinical studies of renal denervation in patients with resistant hypertension using an endovascular radiofrequency ablation methodology have exposed the sympathetic link between these conditions. Renal denervation could be expected to simultaneously affect blood pressure, insulin resistance, sleep disorders, congestion in heart failure, cardiorenal syndrome and diuretic resistance. The striking epidemiologic evidence for coexistence of these disorders suggests common causal pathways. Chronic activation of the sympathetic nervous system has been associated with components of the metabolic syndrome, such as blood pressure elevation, obesity, dyslipidemia, and impaired fasting glucose with hyperinsulinemia. Over 50% of patients with essential hypertension are hyperinsulinemic, regardless of whether they are untreated or in a stable program of treatment. Insulin resistance is related to sympathetic drive via a bidirectional mechanism. In this manuscript, we review the data that suggests that selective impairment of renal somatic afferent and sympathetic efferent nerves in patients with resistant hypertension both reduces markers of central sympathetic drive and favorably impacts diseases linked through central sympathetics-insulin resistance, heart failure, congestion, diuretic resistance, and cardiorenal disorders.

Sonographic findings in primary diseases of renal pyramids

Primary pathologic processes involving the renal pyramids such as papillary necrosis, drug-induced necrosis or calcinosis, cysts, neoplasms, and medullary nephrocalcinosis are rare. Thirty-four patients with primary renal pyramid diseases underwent US evaluation for altered morphology; a 5-MHz transducer was used. In 20 patients site-specific changes in the pyramid (e.g., papillary necrosis at the apex, small cysts at the base in medullary cystic disease, tubular calcification in MSK, corticomedullary hyperechogenicity in oxalosis) were noted on US. Sonographic delineation of the site and pattern of pathologic changes in the renal pyramid may help to identify specific diseases

Patients with renal disease typically have severely calcified peripheral arterial disease. As a result, this population may have worse clinical outcomes following endovascular intervention compared to patients without renal insufficiency. Clinical trials typically exclude this patient population. Analysis of the CONFIRM I-III registries revealed 1105 patients with renal disease (1777 lesions) and 1969 patients without renal disease (2907 lesions) who underwent orbital atherectomy. This subanalysis compared the composite procedural complication rate including dissection, perforation, slow flow, vessel closure, spasm, embolism, and thrombus formation in patients with and without renal disease. Patients with renal disease had a higher prevalence of diabetes (Patherectomy resulted in similar low rates of procedural complications in the renal disease group compared with the non-renal disease group despite more unfavorable baseline clinical and lesion characteristics in the renal disease group.

In rheumatoid arthritis (RA) patients, the risk of both vertebral and non-vertebral fractures is roughly doubled, which is for an important part caused by inflammation-mediated amplification of bone loss and by immobilization. New treatments have become available in the last two decades to treat both RA and osteoporosis. Epidemiology and assessment of osteoporosis and fracture risk (including the influence of RA disease activity and bone-influencing medications such as glucocorticoids), the importance of vertebral fracture assessment in addition to bone density measurement in patients with RA, the use of disease-modifying antirheumatic drugs and their effects on generalized bone loss, and current and possible future anti-osteoporotic pharmacotherapeutic options are discussed with special focus on RA. Assessment of osteoporosis in RA patients should include evaluation of the effects of disease activity and bone-influencing medications such as (the dose of) glucocorticoids, above standard risk factors for fractures or osteoporosis as defined by the FRAX instrument. Disease-modifying antirheumatic drugs are now well able to control disease activity using treat to target strategies. This lowering of disease activity by antirheumatic medications such as anti-TNF-α results in hampering of generalized bone loss; however, no fracture data are currently available. When treating osteoporosis in RA patients, additional focus should be on calcium supplementation, particularly in glucocorticoid users, and also on sufficient vitamin D use. Several anti-osteoporotic medications are now on the market; oral bisphosphonates are most commonly used, but in recent years, more agents have entered the market such as the parenteral antiresorptives denosumab (twice yearly) and zoledronic acid (once yearly), and the anabolic agent parathyroid hormone analogues. New agents, such as odanacatib and monoclonal antibodies against sclerostin, are now being tested and will most likely enlarge the

Osteoporosis is the disease of bone that affected King David of Israel 3000 years ago. This condition is no longer considered to be due to aging alone and is increasingly recognised as a major health concern and accounts for about 1.5 million fractures annually in United States. Objective of this study was to see the frequency of osteoporosis in patients with cirrhosis due to Hepatitis B and C, and any correlation between the Bone Mineral Density (BMD) and duration and stage of the liver disease. Methods: The study was conducted in the Department of Gastroenterology, Postgraduate Medical Institute, Hayatabad Medical Complex, Peshawar, from January 2008 to December 2008. All patients from the OPD or Ward fulfilling the criteria and consenting were included. Physical examination, with special emphasis on any signs of chronic liver disease was performed. Full blood count, platelet count, prothrombin time and INR, liver function tests including serum albumin, and renal function tests were done on all patients. Viral serology was checked for those patients who were either newly diagnosed as cirrhotic or were cirrhotic but not screened for viral markers. Abdominal sonogram was recorded on all patients. The Child's score was calculated for each patient using the clinical and lab parameters. The BMD was calculated for all patients using computer based ultrasound probe. Calcaneum was used for evaluation of BMD. Results: Osteoporosis was found in 26% of subject and osteopenia in 42%, while 32% had BMD in the normal range. The mean T score was -1.483 (+-1.29). The mean duration of liver disease was 3.77 (+-1.56) year. Majority of the patients (81%) were in Child's Class C, followed by Class B and A (16% and 3% respectively). Fifty nine percent of the patients were males with a mean age of 37.65 years, while 41% were females with mean age of 37.76 years. Conclusion: Osteoporosis is a common finding in patients with cirrhosis due to Hepatitis B and C. Osteoporosis is more

Regional migratory osteoporosis is an uncommon self-limiting disease characterized by an arthralgia which migrates between the weight-bearing joints of the lower limb. The radiological features of the disease obtained by conventional radiography, CT, MRI and radionuclide scintigraphy are illustrated by means of five case reports. These range from the most common presentation of sequential, proximal to distal spread in the lower limb to the rare intra-articular form, and disease involving the axial skeleton is also recognized. Clinical and radiographical features often overlap with those of diseases such as transient osteoporosis of the hip and transient bone marrow oedema syndrome, which is reflected in confusing terminology. Histological sampling is usually unnecessary; the radiological features are characteristic and the histological findings are not specific. Regional migratory osteoporosis is associated with systemic osteoporosis. This association is probably under-recognized, and has implications for the pathophysiology of the disease and for treatment

Direct magnification technique of radiographs of the hand in children with chronic renal insufficiency

The characteristic changes of renal osteopathy in the hand are shown by the X-rays of seven children with end stage renal disease using the direct magnification technique. All children had pathologic conditions in the hands. Most frequently tunnelation, spiculae in the phalanges and metaphyseal translucent bands in the forearm were seen. Less constantly acroosteolyses and generalized osteoporosis could be observed. The X-rays of the hands using the direct magnification technique with rare earth film-screen system and a microfocus X-ray tube are sufficient to determine renal osteopathy. If clinical symptoms are present, X-rays of other parts of the skeleton are necessary. By using the above mentioned radiologic technique the radiographic diagnostic effort could be minimized.

A very high rate of osteoporosis, fractures, and low lean mass was observed in patients with chronic obstructive pulmonary disease (COPD). Disease severity was associated with bone and muscle adverse outcomes, while age ≥ 63.5 years old, low lean mass, higher iPTH, and a T-score below - 2.5 were all associated with higher risk of fracture. Osteoporosis is frequently neglected in patients with COPD. We aimed at evaluating the rate of osteoporosis, fractures, and low lean mass in patients with COPD. Ninety-nine patients with COPD (53 women, 64.5 ± 9.6 years old, and 46 men, 65.9 ± 8.0 years old) underwent bone densitometry (DXA) with body composition analyses. Healthy individuals (N = 57) not exposed to tobacco matched by sex, age, and body mass index (BMI) were used as controls. Spirometry, routine laboratory workout, and conventional thoracolumbar radiography surveying for vertebral deformities were performed in all patients. Osteoporosis was found in 40.4% of the COPD patients against only 13.0% of the healthy controls (p = 0.001). Vertebral fractures were seen in 24.4% of the men and 22.0% of the women with COPD. Disease severity (GOLD 3 and 4) was significantly associated with higher risk of vitamin D deficiency (p = 0.032), lower BMD (both men and women at all sites), higher frequency of osteoporosis (in women at all sites), lower skeletal mass index, and higher rate of low lean mass (in both men and women) than healthy controls and COPD patients with milder disease (GOLD 1 and 2). Age was a main predictor of vertebral fractures (OR = 1.164 (1.078-9.297); p lean mass were associated with FEV 1% lean mass, high iPTH, and low bone mass were all significantly associated with fractures in COPD patients.

Highlights: • Single-nucleotide polymorphisms (SNPs) associated with osteoporosis were identified. • SNPs mapped close to or within VDR and ESR1 are associated with bone mineral density. • WNT signaling pathway plays a pivotal role in regulating bone mineral density. • Genetic studies will be useful for identification of new therapeutic targets. - Abstract: Osteoporosis is a skeletal disease characterized by low bone mineral density (BMD) and microarchitectural deterioration of bone tissue, which increases susceptibility to fractures. BMD is a complex quantitative trait with normal distribution and seems to be genetically controlled (in 50–90% of the cases), according to studies on twins and families. Over the last 20 years, candidate gene approach and genome-wide association studies (GWAS) have identified single-nucleotide polymorphisms (SNPs) that are associated with low BMD, osteoporosis, and osteoporotic fractures. These SNPs have been mapped close to or within genes including those encoding nuclear receptors and WNT-β-catenin signaling proteins. Understanding the genetics of osteoporosis will help identify novel candidates for diagnostic and therapeutic targets.

Full Text Available Objective: to study the incidence of osteoporosis (OP in patients with calcium pyrophosphate crystal deposition disease (CPCDD. Subjects and methods. Eighty patients with CPCDD were examined. Bone mineral density (BMD of the forearm, lumbar spine, and femoral neck was determined by dual-energy X-ray absorptiometry. Laboratory diagnosis involved determination of the blood levels of C-reactive protein, parathyroid hormone, calcium, magnesium, and phosphorus and the daily urinary excretion of calcium and phosphates. Results. The patients with OP were significantly older than those with normal BMD and osteopenia. Forearm bones were the most common isolated location of OP and osteopenia. Injuries in the history, traumatic fractures, and the intake of diuretics were somewhat more common in the patients diagnosed with OP. The incidence of hyperparathyroidism did not differ significantly in the groups.

Renal sympathetic denervation (RSD) is emerging as a new therapeutic option for patients with severe hypertension refractory to medical therapy. The presence of a renal artery stenosis may be both a cause of secondary hypertension and a contraindication to RSD if a renal artery stent is implanted; therefore, the definition of the functional importance of a renal artery stenosis in a patient with refractory hypertension is crucial. We describe the imaging and functional intravascular assessment of an angiographically severe stenosis of the renal artery in a patient with severe refractory hypertension, by means of intravascular ultrasound (IVUS), and measurement of the translesional pressure gradient with a pressure wire. Pressure wire examination excluded any severity of the stenosis, and IVUS showed the presence of a dissected plaque that resolved spontaneously after 3 months of intensive medical therapy and high-dose statin. Subsequently the patient was treated with RSD, achieving a significant effect on blood pressure control. Intravascular imaging and functional assessment of renal artery anatomy in patients with atherosclerotic disease may prove particularly suited to patients with refractory hypertension and multilevel vascular disease who are considered for endovascular therapies, either renal artery stenting or RSD.

BACKGROUND: While increased plasma cholesterol is a well-established cardiovascular risk factor in the general population, this is not so among patients with chronic renal disease. We hypothesized that the transvascular lipoprotein transport, in addition to the lipoprotein concentration in plasma......, determines the degree of atherosclerosis among patients with chronic renal disease. METHODS: We used an in vivo method for measurement of transvascular transport of low-density lipoprotein (LDL) in 21 patients with chronic renal disease and in 42 healthy control patients. Autologous 131-iodinated LDL...... was reinjected intravenously, and the 1-hour fractional escape rate was taken as index of transvascular transport. RESULTS: Transvascular LDL transport tended to be lower in patients with chronic renal disease than in healthy control patients [3.3 (95% CI 2.4-4.2) vs. 4.2 (3.7-4.2)%/hour; NS]. However...

Full Text Available Abstract Background To evaluate the impact of osteoporosis on the patients' quality of life, particularly in the absence of fractures. Methods 100 post-menopausal women (age 50-85 - 62 with uncomplicated primary osteoporosis and 38 with primary osteoporosis complicated by vertebral fractures; all already treated - were studied using two validated questionnaires: Qualeffo-41 for quality of life in osteoporosis, and Zung for depression. Data were compared to those of 35 controls of comparable age, affected by a different chronic disease (hypothyroidism. Results Family history of osteoporosis and T-score of spine were similar in the two subgroups of osteoporotic women. Body mass index, age at menopause and education level were similar in the two subgroups of osteoporotic women and in the control group. The patients affected by osteoporosis perceived it as a disease affecting their personal life with undesirable consequences: chronic pain (66% of women with fractures and 40% of women without fractures, impaired physical ability, reduced social activity, poor well-being (21% of women without fractures and depressed mood (42% of women irrespective of fractures. Overall, 41% of the women showed a reduced quality of life. On the contrary, in the control group only 11% reported a reduced quality of life. Conclusion The quality of life of osteoporotic patients should be investigated even before fractures, in order to develop appropriate counselling, support and care interventions to help patients develop efficient strategies for accepting the disease and coping with it.

We present an unusual patient who simultaneously had severe renal artery stenosis RAS and Cushings syndrome. The case highlights the difficulty of reaching a specific diagnosis of Cushings syndrome and the possible interaction between Cushings syndrome and some other concurrent illnesses that this patient had. A 37-year old man presented with severe hypertension HTN and uncontrolled diabetes mellitus DM without clear physical signs of Cushings syndrome. He was found to have severe osteoporosis, proximal myopathy, several cutaneous warts, tinea versicolor, and chronic viral hepatitis. Captopril-stimulated renal scan and renal artery angiogram revealed severe RAS. Partial balloon dilatation of RAS led to improvement in HTN. Unexpectedly, urine free cortisol 24 hour was found extremely high. Serum adrenocorticotropic hormone ACTH was also elevated and high dose dexamethasone suppression tests were inconclusive. Several imaging studies failed to localize the source of ACTH. Despite normal MRI of the pituitary gland, bilateral inferior petrosal sinus sampling IPSS localized the source of ACTH secretion to the right side of the pituitary gland and right anterior hemihypophysectomy resulted in cure of Cushings disease, HTN, DM, and tinea versicolor with significant improvement in cutaneous warts, osteoporosis, and chronic hepatitis. In conclusion, RAS and Cushings syndrome may occur together. Significant hypercortisolemia can occur without clear signs of Cushings syndrome. Controlling hypercortisolemia is of paramount importance when treating chronic infections in patients with Cushing's syndrome. (author)

To evaluate the reproducibility and utility of quantitative magnetic resonance imaging (MRI) sequences for the assessment of kidneys in young adults with normal renal function (eGFR ranged from 90 to 130 mL/min/1.73 m 2 ) and patients with early renal disease (autosomal dominant polycystic kidney disease). This prospective case-control study was performed on ten normal young adults (18-30 years old) and ten age- and sex-matched patients with early renal parenchymal disease (autosomal dominant polycystic kidney disease). All subjects underwent a comprehensive kidney MRI protocol, including qualitative imaging: T1w, T2w, FIESTA, and quantitative imaging: 2D cine phase contrast of the renal arteries, and parenchymal diffusion weighted imaging (DWI), magnetization transfer imaging (MTI), blood oxygen level dependent (BOLD) imaging, and magnetic resonance elastography (MRE). The normal controls were imaged on two separate occasions ≥24 h apart (range 24-210 h) to assess reproducibility of the measurements. Quantitative MR imaging sequences were found to be reproducible. The mean ± SD absolute percent difference between quantitative parameters measured ≥24 h apart were: MTI-derived ratio = 4.5 ± 3.6%, DWI-derived apparent diffusion coefficient (ADC) = 6.5 ± 3.4%, BOLD-derived R2* = 7.4 ± 5.9%, and MRE-derived tissue stiffness = 7.6 ± 3.3%. Compared with controls, the ADPKD patient's non-cystic renal parenchyma (NCRP) had statistically significant differences with regard to quantitative parenchymal measures: lower MTI percent ratios (16.3 ± 4.4 vs. 23.8 ± 1.2, p quantitative measurements was obtained in all cases. Significantly different quantitative MR parenchymal measurement parameters between ADPKD patients and normal controls were obtained by MT, DWI, BOLD, and MRE indicating the potential for detecting and following renal disease at an earlier stage than the conventional qualitative imaging techniques.

We report our contemporary experiences with renal autotransplantation in patients with complicated renal vascular diseases and/or complex ureteral injuries. Since its first performance, renal autotransplantation has been steadily improved and become a safe and effective procedure. Between 1998 and 2006, 6 renal autotransplantations in 6 patients were performed at the University Medical Center of Leipzig. After nephrectomy and renal perfusion ex vivo, the kidney was implanted standardized in the fossa iliaca. The vessels were anastomized to the iliac vessels, the ureter was reimplanted in an extravesical tunneled ureteroneocystostomy technique according to Lich-Gregoir. Demographic, clinical, and laboratory data of the patients were collected and analyzed for pre-, intra-, and postoperative period. Indications for renal autotransplantation were complex renovascular diseases in 2 patients (1 with fibromuscular dysplasia and 1 with Takayasu's arteritis) and in 4 patients with complex ureteral injuries. The median duration of follow-up was 9.7 years (range: 5.6-13.3). The laboratory values of our 6 patients showed improvements of creatinine, urea and blood pressure levels in comparison to the preoperative status at the end of follow-up period. The present study reports excellent results of renal autotransplantation in patients with renovascular disease or complex ureteric injuries. After a median follow-up of 9.7 years all 6 patients present with stable renal function as well as normal blood pressure values. Postoperative complications were observed with a rate comparable to other studies.

Vitamin K, osteoporosis and degenerative diseases of ageing.

Vermeer, Cees; Theuwissen, Elke

The function of vitamin K is to serve as a co-factor during the post-translational carboxylation of glutamate (Glu) residues into γ-carboxyglutamate (Gla) residues. The vital importance of the Gla-proteins essential for normal haemostasis is well recognized. During recent years, new Gla-containing proteins have been discovered and the vitamin K-dependent carboxylation is also essential for their function. It seems, however, that our dietary vitamin K intake is too low to support the carboxylation of at least some of these Gla-proteins. According to the triage theory, long-term vitamin K inadequacy is an independent, but modifiable risk factor for the development of degenerative diseases of ageing including osteoporosis and atherosclerosis.

Osteoporosis in men

Full Text Available Osteoporotic fractures are the leading cause of morbidity and mortality among aging men. 30% of all hip fractures occur in men, and mortality resulting from not only the hip fracture, but also the spine and other major osteoporotic fractures, is significantly higher in men than in women. As in women, hypogonadism is the best documented risk factor for developing osteoporosis in men. In older men, testosterone levels are negatively correlated with the risk of fractures, and it seems that this age-related testosterone deficiency should not be considered as one of the many causes of secondary osteoporosis, rather one of the major and most important mechanisms of senile osteoporosis. Acute hypogonadism induced by ablation treatment for prostate cancer (surgical or pharmacological castration, antiandrogen therapy is associated with an extremely high risk of fracture. Other documented causes of bone loss in men are cigarette smoking and alcohol abuse, and a number of diseases that require corticosteroid treatment. Pharmacotherapy of osteoporosis should be recommended to all men with a diagnosed osteoporotic fracture and all men with a high 10-year absolute fracture risk (FRAXTM. Not all drugs registered for the treatment of postmenopausal osteoporosis have been registered for the treatment of osteoporosis in men, and others have not been the subject of long-term and costly clinical trials required for such registration. The risk reduction of new fractures was documented only for treatment with zoledronic acid. Risedronate, strontium ranelate, teriparatide, and denosumab in men increase in bone mineral density comparable to that seen in postmenopausal women.

[Osteoporosis and stress].

Science.gov (United States)

Kumano, Hiroaki

There may be three ways of relationship between stress and osteoporosis. The first is that stress induces some physiological changes leading to osteoporosis. The second is that stress induces behavioral distortion of eating, drinking, exercise, and sleep habits, which leads to osteoporosis. The third is that osteoporosis, on the other hand, brings about anxiety, depression, loss of social roles, and social isolation, which leads to stress. The susceptible sex and age groups are postmenopausal women and young women. The abrupt decrease of estrogen in postmenopausal women promotes reabsorption of bone, and it was also reported that the increase of interleukin-6 (IL-6) that is downstream of estrogen was related to the production of osteoclast and to the development of disability of the aged. Regarding the association with stress, while it was reported that depression or depressive states directly increased inflammation-induced cytokines including IL-6, it was also pointed out that stress-induced easy infectious may produce chronic infection, which indirectly increases inflammation-induced cytokines. Anorexia Nervosa that is assumed to be associated with adolescent developmental stress is noteworthy in young women. Amenorrhea is always present in this disease, and in addition to bone reabsorption associated with estrogen deficiency, the decrease of bone formation associated with malnutrition may be related to the development of osteoporosis.

The proportion of end-stage renal disease (ESRD) cases which may wholly or partially be caused by occupational exposures is not known. However, a number of known and suspect nephrotoxins are in wide use in American Industry. These include lead, mercury, uranium, solvents, silica, arsenic, pesticides, and beryllium. Etiological information is difficult to obtain because exposures typically go unnoticed until considerable dysfunction has ensued. Epidemiological data show an increased number of deaths from renal cancer in workers in the petroleum industry and cases of renal cancer have been reported in workers in the lead industry. Etiologic diagnosis of ESRD of toxic origin would require periodic screening of certain high-risk groups. Non-invasive tests which show promise for determination of renal metal burden include neutron activation analysis, isotope dilution analysis and the use of chelating agents which selectively mobilize metals from the kidneys into the urine. Genetic susceptibility to industrial nephrotoxins should be investigated using recombinant DNA technology

Renal disease and mitochondrial genetics.

Rötig, Agnès

Respiratory chain (RC) deficiencies have long been regarded as neuromuscular diseases mainly originating from mutations in the mitochondrial DNA. Oxidative phosphorylation, i.e. adenosine triphosphate (ATP) synthesis-coupled electron transfer from substrate to oxygen through the RC, does not occur only in the neuromuscular system. Therefore, a RC deficiency can theoretically give rise to any symptom, in any organ or tissue, at any age and with any mode of inheritance, owing to the dual genetic origin of RC enzymes (nuclear DNA and mitochondrial DNA). Mitochondrial diseases can give rise to various syndromes or association, namely, neurologic and neuromuscular diseases, cardiac, renal, hepatic, hematological and endocrin or dermatological presentations. The most frequent renal symptom is proximal tubular dysfunction with a more or less complete de Toni-Debre-Fanconi Syndrome. A few patients have been reported with tubular acidosis, Bartter Syndrome, chronic tubulointerstitial nephritis or nephrotic syndrome. The diagnosis of a RC deficiency is difficult when only renal symptoms are present, but should be easier when another, seemingly unrelated symptom is observed. Metabolic screening for abnormal oxidoreduction status in plasma, including lactate/pyruvate and ketone body molar ratios, can help to identify patients for further investigations. These include the measurement of oxygen consumption by mitochondria and the assessment of mitochondrial respiratory enzyme activities by spectrophotometric studies. Any mode of inheritance can be observed: sporadic, autosomal dominant or recessive, or maternal inheritance.

The characteristic changes of renal osteopathy in the hand are shown by the X-rays of seven children with end stage renal disease using the direct magnification technique. All children had pathologic conditions in the hands. Most frequently tunnelation, spiculae in the phalanges and metaphyseal translucent bands in the forearm were seen. Less constantly acroosteolyses and generalized osteoporosis could be observed. The X-rays of the hands using the direct magnification technique with rare earth film-screen system and a microfocus X-ray tube are sufficient to determine renal osteopathy. If clinical symptoms are present, X-rays of other parts of the skeleton are necessary. By using the above mentioned radiologic technique the radiographic diagnostic effort could be minimized. (orig.)

Polycystic renal disease are congenital disorders, most of which are fatal in the postnatal period. A series of ten cases of polycystic renal disease diagnosed prenatally by ultrasonography is presented. Diagnostic criteria of ultrasonography for cystic renal disease are; 1. enlarge kidney (4 cases) 2. echogenic density of kidney (3 cases) 3. 0.4 - 0.9cm sized multiple cysts within the renal cortex (3 cases) 4. decreased amount of amniotic fluid (4 cases) 5. hydronephrosis (4 cases) 6. distended bladder (2 cases) 7. absence of bladder (2 cases) Eight of ten cases were confirmed by autopsy. Seven cases had other associated congenital anomalies, i.e. pulmonary hypoplasia (5), hepatic fibrosis (3), congenital heart disease (3), tracheoesophageal fistula with imperforate anus (1), caudal regression syndrome (1), Meckel-Gruber syndrome (1) and ambiguous genitalia (2). Additional cytogenetic study of the fetus and the careful family history taking followed by prenatal diagnosis of cystic renal disease.

To evaluate whether sono-guided percutaneous automated gun biopsy is also useful in pediatricpatients with renal diseases. In the prone position of twenty pediatric patients with renal parenchymal diseases, percutaneous biopsy was done through lateral aspect of the lower pole of left kidney with automated biopsy gun under the guidance of ultrasonography. The biopsy needle was either of 18 or 20 gauge. The obtained core of renal tissue was examined with light, immunofluorescent or electron microscope by the renal pathologist. In 18 among 20 patients, adequate renal tissue core sufficient to be pathologically diagnosed was obtained. The histologic findings were as follows : IG A nephropathy (n = 2), lupus nephritis (n =2), minimal change glomerulonephritis (n = 5), membranoproliferative glomerulonephritis (n = 3), mesangialproliferative glomeru-lonephritis (n = 1), diffuse proliferative glomerulonephritis (n = 3), focalglomerulo-sclerosis (n = 1), membranous glomerulopathy (n = 1). No significant complications occurred during or after the biopsy. Sono-guided percutaneous renal biopsy using automated biopsy gun is also useful todiagnose renal parenchymal diseases without significant complications in pediatric patients

2010-09-01

Full Text Available Osteoporosis in men is frequently not considered, underdiagnosed and often undertreated. In contrast with osteoporosis occurring in women, the genesis is frequently secondary (30-60% with a complex diagnostic approach. A careful anamnesis and physical examination associated with laboratory and instrumental evaluation are necessary for an accurate diagnosis. The clinical case presented concerns a 70-year-old man with negative family history for osteoporosis and a personal history of depression, HBV carrier, and chronic obstructive pulmonary disease (COPD in a heavy ex-smoker with history of alcoholism. The comprehensive geriatric evaluation allowed us to diagnose a multifactorially secondary osteoporosis associated to osteomalacia probably generated by the combination of alcohol abuse with consequent severe malnutrition, heavy smoking and COPD, physical inactivity and rapid weight loss.

Osteoporosis and diabetes

Directory of Open Access Journals (Sweden)

M. Barbagallo

Full Text Available Diabetes mellitus and osteoporosis are chronic diseases with an elevated and growing incidence in the elderly. Recent epidemiological studies have demonstrated an elevated risk of hip, humerus and foot fractures in elder diabetic subjects. While type 1 diabetes is generally associated with a mild reduction in bone mineral density (BMD, type 2 diabetes, more prevalent in old subjects, is frequently linked to a normal or high BMD. Studies on experimental models of diabetes have suggested an altered bone structure that may help to explain the elevated risk of fractures observed in these animals and may as well help to explain the paradox of an incremented risk of fractures in type 2 diabetic elderly in the presence of normal or elevated BMD. In addition, diabetic elderly have an increased risk of falls, consequent at least in part to a poor vision, peripheral neuropathy, and weaken muscular performance. Diabetes may affect bone tissue by different mechanisms including obesity, hyperinsulinemia, deposit of advanced glycosilation end products in collagen fibre, reduced circulating levels of IGF-1, hypercalciuria, renal function impairment, microangiopathy and chronic inflammation. A better understanding of these mechanisms may help implement the prevention of fractures in the growing population of mature diabetics.

Osteoporosis in premenopausal women.

Science.gov (United States)

Langdahl, Bente L

2017-07-01

The scope of this review was to review the newest developments in the context of the existing knowledge on premenopausal bone fragility. Fragility fractures are common in postmenopausal women and men and diagnostic criteria for osteoporosis have been agreed and multiple pharmacological treatments have been developed over the last 25 years. In premenopausal women, fragility fractures and very low bone mass are uncommon and osteoporosis in premenopausal women has therefore attracted much less interest. Recent studies have highlighted that lifestyle and dietary habits affect premenopausal bone mass. Bone mass may be improved by sufficient intake of calcium and vitamin D together with increased physical activity in premenopausal women with idiopathic osteoporosis. If pharmacological treatment is needed, teriparatide has been demonstrated to efficiently increase bone mass; however, no fracture studies and no comparative studies against antiresorptive therapies have been conducted. Pregnancy affects bone turnover and mass significantly, but pregnancy-associated osteoporosis is a rare and heterogeneous condition. The diagnosis of osteoporosis should only be considered in premenopausal women with existing fragility fractures, diseases or treatments known to cause bone loss or fractures. Secondary causes of osteoporosis should be corrected or treated if possible. The women should be recommended sufficient intake of calcium and vitamin and physical activity. In women with recurrent fractures or secondary causes that cannot be eliminated, for example glucocorticoid or cancer treatment, pharmacological intervention with bisphosphonates or teriparatide (not in the case of cancer) may be considered.

Bone fluoride determination for clinical investigation of osteoporosis

Sodium fluoride is the therapeutic agent known to stimulate bone growth with net increase in bone mineral mass in patients afflicted with osteoporosis, a common crippling bone disease. In order to study the effect of sodium fluoride treatment, a method of analysis for fluoride in bone has been developed using Neutron Activation Analysis (NAA). The technique proved to be simple, fast, reliable and non-destructive. Thus the sample, often bone biopsy specimen, is available, after fluoride analysis, for further histological studies. NAA was used to analyze both fluoride and calcium in the bone and the results expressed as F/Ca ratio was meaningful since it normalizes the fluoride to bone mineral mass which is the important factor in this study. Four years of fluoride treatment of osteoporotics showed significant increase of bone mass (up to 30%) in several patients. These increases were associated with histological bone picture of fluorosis. In the case of patients with renal osteodystrophy, there was evidence that fluorosis contributes to the bone disease. 3 references, 2 figures, 2 tables

We evaluated the effectiveness and clinical usefulness of percutaneous renal biopsy by using automated biopsy gun under the real-time ultrasonographic guidance that was performed in 17 patients with diffuse renal disease. We retrospectively analysed the histopathological diagnosis and the patients' status after percutaneous renal biopsy.Adequate amount of tissue for the histologic diagnosis could be obtained in al patients. Histopathologic diagnosis included the minimal change nephrotic syndrome in 6 patients, the membrano proliferative glomerulonephritis in 4,the membranous glomerulonephritis in 2, the glomerulosclerosis in 2, Ig A nephropathy in 2, and the normal finding in 1. Significant complication occurred in only one patient who developed a transient loss of sensation at and around the biopsy site. In conclusion, automated biopsy gun was a very useful device in performing percutaneous biopsy for diffuse renal disease with a high success rate and a low complication rate

Mutations in MYH9 gene encoding the nonmuscle myosin heavy chain IIA (NMMHC-IIA) are related to a number of rare autosomal-dominant disorders which has been known as May-Hegglin disease, Sebastian syndrome, Fechtner syndrome and Epstein syndrome. Their common clinical features are congenital macrothrombocytopaenia and polymorphonuclear inclusion bodies, in addition to a variable risk of developing proteinuria, chronic kidney disease progressing toward end stage, sensorineural deafness and presenile cataracts. The term MYH9 related disease (MYH9-RD) describes the variable expression of a single illness encompassing all previously mentioned hereditary disorders. Renal involvement in MYH9- RD has been observed in 30% of patients. Mutant MYH9 protein, expressed in podocytes, mesangial and tubular cells, plays a main role in foot process effacement and in development of nephropathy. Interestingly, the MYH9 gene is currently under investigation also for his possible contribution to many other non-hereditary glomerulopathies such as focal global glomerulosclerosis (hypertensive nephrosclerosis), idiopathic focal segmental glomerulosclerosis, C1q nephropathy and HIV-associated nephropathy. In this review we are aimed to describe renal diseases related to MYH9 disorders, from the hereditary disease to the acquired disorders, in which MYH9-gene acts as a "renal failure susceptibility gene".

Yuen, Noah K; Ananthakrishnan, Shubha; Campbell, Michael J

2016-01-01

Renal hyperparathyroidism (rHPT) is a common complication of chronic kidney disease characterized by elevated parathyroid hormone levels secondary to derangements in the homeostasis of calcium, phosphate, and vitamin D. Patients with rHPT experience increased rates of cardiovascular problems and bone disease. The Kidney Disease: Improving Global Outcomes guidelines recommend that screening and management of rHPT be initiated for all patients with chronic kidney disease stage 3 (estimated glomerular filtration rate, < 60 mL/min/1.73 m(2)). Since the 1990s, improving medical management with vitamin D analogs, phosphate binders, and calcimimetic drugs has expanded the treatment options for patients with rHPT, but some patients still require a parathyroidectomy to mitigate the sequelae of this challenging disease.

Addison's disease is a rare condition. Its onset of symptoms most often is nonspecific contributing to a diagnostic and therapeutic delay. Acute renal failure can be the first manifestation of this disease. We report the case of a patient with Addison's disease who was initially treated for acute renal failure due to multiple myeloma and whose diagnosis was adjusted thereafter. Patient's condition dramatically improved after treatment with intravenous rehydration; injectable hydrocortisone.

Bone scan and radiographs were evaluated in 80 patients with metabolic bone disease (27 with osteoporosis, 14 with primary hyperparathyroidism, 24 with renal osteodystrophy and 15 with osteomalacia). The bone scan did not suggest a metabolic bone disorder in any of 27 patients with histologically proven osteoporosis. In 22 (81%) patients radiographs were reported as showing osteoporosis. In 19 (70%) vertebral fractures were seen on X-ray while these were noted in 11 (41%) patients on the bone scan. Vertebral fractures were usually visualised on the bone scan when these had occurred less than one year previously. In primary hyperparathyroidism the bone scan was suggestive of a metabolic bone disorder in 7 of 14 (50%) patients, while radiographs were reported as showing evidence of hyperparathyrodism in three (21%) cases. The bone scan suggested the presence of a metabolic bone disorder in all 24 patients with renal osteodystrophy and 15 patients with osteomalacia while the correct diagnosis was obtained in 14 (58%) and nine (60%) of these patients on X-ray. It is concluded that the bone scan is the more sensitive investigation in patients with osteomalacia, primary hyperparathyroidism and renal osteodystrophy. For osteoporosis radiology is the investigation of choice but the bone scan may be of value in assessing the duration of vertebral collapse. (author)

2008-05-01

Full Text Available Osteoporosis is the most common metabolic bone disease and is characterized by the shrinkage in bone mass and the distruction of bone quality, thus conferring a higher risk for fractures and injuries. Osteoporosis reaches clinical attention when it is severe enough to induce microfractures and the collapsing of vertebral bodies manifesting with back aches or predisposition to other bone fractures. The aim of the study was to establish a statistic-numeric report between women and men in subjects diagnosed with osteoporosis through DEXA that present with a clinical simptomatology. We studied a group of subjects of masculine and feminine genders that have been diagnosed with osteoporosis through DEXA at the EURORAD clinic in Oradea from 01.01.2007-to present time .The result of the study was that the simptomatology of osteoporosis with pain and even cases of fractures is more obvious in female subjects then in male patients; statistically ,a woman/man report of 6.1/1 was established.

Recent trends in the diagnosis of osteoporosis

Osteoporosis is a progressive systemic disease of the skeleton that is characterized by reduced mass and impaired mikroarhitektonika bone, leading to enhanced bone fragility and increased risk of fractures. The development of osteoporosis is painless and progresses slowly and gradually, without manifested symptoms over the years, so that patients learn about the disease only at later stages of development or, most often after the occurrence of fracture. By dual-energy X-ray absorptiometry (DXA) of the spine and femoral neck can be diagnosed, to estimate fracture risk and monitor treatment. In the aspect of diagnostic methods such as peripheral dual-energy X-ray absorptiometry (rDXA), quantitative ultrasound bone (QRS) and quantitative computed tomography (QCT) have their place. Key words: Dual-Energy X-Ray Absorptiometry. Osteoporosis

Full Text Available La drepanocitosis está asociada con un amplio espectro de alteraciones renales que tienen su base en la falciformación de los eritrocitos en los vasos de la médula renal, que conduce a fenómenos de isquemia, microinfartos y anomalías de la función tubular. Se producen también alteraciones glomerulares funcionales reversibles de la autorregulación renal (hiperfiltración, que pueden conducir a cambios anatómicos irreversibles con glomeruloesclerosis segmentaria focal. Estas anomalías se expresan tempranamente como microalbuminuria, proteinuria y de forma mas tardía, como síndrome nefrótico e insuficiencia renal crónica. Medidas terapéuticas como el uso de inhibidores de la enzima convertidora de la angiotensina II, de los bloqueadores del receptor de la angiotensina II, asociados o no con la hidroxiurea, pueden prevenir o retardar el daño glomerular. En el presente trabajo se exponen de forma resumida aspectos relacionados con la fisiopatología del daño renal en la drepanocitosis y su tratamiento.Sickle cell disease is associated with a wide range of renal disorders resulting from the falciformation of erythrocytes in vessels of the renal medulla, leading to ischemia, microinfarctions and tubular function abnormalities. Reversible glomerular functional renal self-regulation disorders (hyperfiltration also occur, which may lead to irreversible anatomical changes with focal segmental glomerular sclerosis. These anomalies are expressed at an early stage as microalbuminuria and proteinuria, and at a later stage as nephrotic syndrome and chronic renal failure. Therapeutic measures such as the use of angiotensin-II converting enzyme inhibitors and angiotensin-II receptor blockers, associated or not with hydroxyurea, may either prevent or delay glomerular damage. The paper succinctly presents the physiopathology of renal damage in drepanocytosis and its treatment.

Renal disease includes conditions affecting the glomeruli, tubules, interstitium, pelvis, and vasculature. Diseases of the kidney include glomerular diseases, diseases of the tubules and interstitium, diseases of renal pelvis, and developmental abnormalities. Renal tissue samples (n = 70) submitted to the Department of Veterinary Pathology of Konkuk University from 2003 to 2008 were included in this study. Tissue histopathology was performed using light microscopy with hematoxylin and eosin stains. Masson's trichrome, Congo Red, and Warthin starry silver staining were applied in several individual cases. Glomerular diseases (22.9%), tubulointerstitial diseases (8.6%), neoplastic diseases (8.6%), conditions secondary to urinary obstruction (24.3%), and other diseases (35.7%) were identified. Glomerulonephritis (GN) cases were classified as acute proliferative GN (5.7%), membranous GN (4.3%), membranoproliferative GN (4.3%), focal segmental GN (2.9%), and other GN (4.2%). The proportion of canine GN cases presently identified was not as high as the proportions identified in human studies. Conversely, urinary obstruction and end-stage renal disease cases were relatively higher in dogs than in human populations. PMID:21113095

Renal diseases are a significant problem among children and are one of the common causes of hospital admission. These patients need comprehensive services for early identification and management.

Role of the intrarenal renin-angiotensin system in the progression of renal disease.

Urushihara, Maki; Kagami, Shoji

2017-09-01

The intrarenal renin-angiotensin system (RAS) has many well-documented pathophysiologic functions in both blood pressure regulation and renal disease development. Angiotensin II (Ang II) is the major bioactive product of the RAS. It induces inflammation, renal cell growth, mitogenesis, apoptosis, migration, and differentiation. In addition, Ang II regulates the gene expression of bioactive substances and activates multiple intracellular signaling pathways that are involved in renal damage. Activation of the Ang II type 1 (AT1) receptor pathway results in the production of proinflammatory mediators, intracellular formation of reactive oxygen species, cell proliferation, and extracellular matrix synthesis, which in turn facilities renal injury. Involvement of angiotensinogen (AGT) in intrarenal RAS activation and development of renal disease has previously been reported. Moreover, studies have demonstrated that the urinary excretion rates of AGT provide a specific index of the intrarenal RAS status. Enhanced intrarenal AGT levels have been observed in experimental models of renal disease, supporting the concept that AGT plays an important role in the development and progression of renal disease. In this review, we focus on the role of intrarenal RAS activation in the pathophysiology of renal disease. Additionally, we explored the potential of urinary AGT as a novel biomarker of intrarenal RAS status in renal disease.

The shift in health care delivery from a subspecialty to primary care system has transferred the responsibility of preventing osteoporotic fractures from specialists in metabolic bone disease to the web of physicians--family practitioners, general internists, pediatricians, and gynecologists--who provide the bulk of primary care. The challenge for this group of physicians is to decrease the rising prevalence of osteoporotic hip and vertebral fractures while operating within the cost parameters. It is the goal of this brief summary to provide primary practitioners with focused guidelines for the management of postmenopausal osteoporosis based on new and exciting developments. Prevention and treatment will change rapidly over the next decade and these advances will require changes in these recommendations. We identified patients at risk for osteoporosis and provided indications for bone mass measurement, criteria for diagnosis of osteoporosis, therapeutic interventions, and biochemical markers of the disease. Prevention and treatment are discussed, including hormone replacement therapy and use of calcitonin, sodium fluoride, bisphosphonates, and serum estrogen receptor modulators. Postmenopausal osteoporosis should no longer be an accepted process of aging. It is both preventable and treatable. Primary care physicians must proactively prevent and treat osteoporosis in their daily practice, and combination therapies are suggested.

To review the literature to assess whether the fact that osteoporosis is chiefly considered a disease of the older population was reflected in research in the area of the management of osteoporosis and to determine the extent of ageism in studies on the management of osteoporosis. Review. All randomized control trials on the management of osteoporosis entered in the Cochrane Library Database that reported mean age were included. Exclusion criteria were also examined. Of 284 randomized control trials identified, 102 were eligible for inclusion. Older adult trail participants. Mean age of participants and exclusion criteria used were analyzed. The mean age of all participants was 64.0, despite the fact that the average age at hip fracture is 83 for women and 84 for men. Overall, the mean age of those presenting with hip fractures is 84.8. Twenty-four (23%) of the 102 trials used older age as an exclusion factor. Other exclusion factors were long time since menopause, impaired cardiac or pulmonary function, dependent in ambulation, any severe comorbidity, dementia or any cognitive impairment, recent history of peptic ulcer disease or erosive gastric disease, uncontrolled hypertension, and psychiatric illness. These data show a distinct difference between the mean age of participants in studies of the management of osteoporosis and the mean age of those presenting with hip fractures. Given that osteoporosis is the leading cause of hip fractures, this finding could have a significant effect on future studies in this area. It would follow that future research should include a cohort of an age that is more reflective of those most likely to experience the adverse effects of osteoporosis. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

An association between celiac disease and renal diseases has been suggested, but the results are controversial. To investigate the prevalence of celiac disease autoimmunity among individuals undergoing renal biopsies and to evaluate whether co-existent celiac autoimmunity influences the clinical outcome of the renal disease. The prevalence of celiac autoimmunity (previous diagnosis of celiac disease or positive tissue transglutaminase antibodies) was determined in 827 consecutive patients undergoing kidney biopsies due to clinical indications. Up to 15 years' follow-up data on kidney function and co-morbidities were obtained. Celiac autoimmunity was found in 45 (5.4%) patients. Among the IgA nephropathy patients, 8.2% of had celiac autoimmunity. At the time of kidney biopsy and after a median follow-up of 5 to 6 years, renal function measured by estimated glomerular filtration rate (eGFR) was inferior in IgA nephropathy patients with celiac autoimmunity compared to those without it (P=0.048 and P=0.022, respectively). The prevalence of celiac autoimmunity seems to be high in patients undergoing renal biopsies, especially in patients with IgA nephropathy. Such autoimmunity may be associated with worse renal function in IgA nephropathy. Hence the co-existence of celiac disease should be taken into consideration when treating patients with renal diseases. Copyright © 2017 Editrice Gastroenterologica Italiana S.r.l.

Protein intake in renal and hepatic disease.

Science.gov (United States)

Ambühl, Patrice M

2011-03-01

The kidney and the liver play a central role in protein metabolism. Synthesis of albumin and other proteins occurs mainly in the liver, whereas protein breakdown and excretion are handled through an intricate interaction between these two organ systems. Thus, disease states of either the liver and/or the kidney invariably result in clinically relevant disturbances of protein metabolism. Conversely, metabolic processes regulated by these two organs are directly affected by dietary protein intake. Of particular importance in this respect is the maintenance of acid/base homeostasis. Finally, both the amount and composition of ingested proteins have a direct impact on renal function, especially in a state of diseased kidneys. Consequently, dietary protein intake is of paramount importance in patients with chronic nephropathy and renal insufficiency. Limitation of ingested protein, particularly from animal sources, is crucial in order to slow the progression of chronic kidney disease and impaired renal function. In contrast, patients with chronic renal failure undergoing renal replacement therapy by hemodialysis or peritoneal dialysis, have an increased protein demand. The syndrome of "protein-energy malnutrition" is a relevant factor for morbidity and mortality in this population and requires early detection and vigorous treatment. Protein intake in patients with cirrhosis of the liver should not be diminished as has been earlier suggested but rather increased to 1.0 - 1.2 g/kg body weight/day, in order to prevent protein malnutrition. Moderate restriction depending on protein tolerance (0.5 - 1.2 g/kg body weight/day), with the possible addition of branched chain amino acids (BCAA), has been recommended only in patients with advanced hepatic encephalopathy. Proteins of plant origin are theoretically superior to animal proteins.

Diabetes and chronic kidney disease (CKD) are two of the commonest long-term conditions. One-fifth of patients with diabetes will have CKD, and diabetes is the commonest cause of advanced kidney disease. For most patients these comorbidities will be managed in primary care with the focus on cardiovascular prevention. Many patients with more advanced disease and complications require joint care from multidisciplinary specialist teams in diabetes and renal disease to ensure that care is consistent and coordinated. Models of joint speciality care, include joint registry management, parallel clinics, shared consulting and case discussion, but require more evaluation than has currently been performed. These underpin more informal interactions between the specialist teams. A local model of care for diabetes and renal disease that incorporates the roles of primary care, members of multidisciplinary teams and speciality care should be agreed, resourced appropriately and its effectiveness monitored. © 2012 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Emerging therapies for the treatment of osteoporosis

Directory of Open Access Journals (Sweden)

Garima Bhutani

2013-01-01

Full Text Available Osteoporosis is a chronic disease of the osseous system characterized by decreased bone strength and increased fracture risk. It is due to an imbalance in the dynamic ongoing processes of bone formation and bone resorption. Currently available osteoporosis therapies like bisphosphonates, selective estrogen receptor modulators (SERMs, and denosumab are anti-resorptive agents. Parathyroid hormone analogs like teriparatide are the only anabolic agents currently approved for osteoporosis treatment. The side-effects and limited efficacy of the presently available therapies has encouraged extensive research into the pathophysiology of the disease and newer drug targets for its treatment. The novel anti-resorptive agents being developed are newer SERMs, osteoprotegerin, c-src (cellular-sarcoma kinase inhibitors, αVβ3 integrin antagonists, cathepsin K inhibitors, chloride channel inhibitors, and nitrates. Upcoming anabolic agents include calcilytics, antibodies against sclerostin and Dickkopf-1, statins, matrix extracellular phosphoglycoprotein fragments activin inhibitiors, and endo-cannabinoid agonists. Many of these new drugs are still in development. This article provides an insight into the emerging drugs for the treatment of osteoporosis.

Some form of imaging procedure should be used to document the presence of infection of the upper urinary tract in troublesome cases in children. During the past several years, sonography, nuclear radiology, and computed tomography (CT) have had a significant influence on renal imaging. The purpose of this article is to reevaluate the noninvasive imaging procedures that can be used to diagnose pediatric renal inflammatory disease and to assess the relative value of each modality in the various types of renal infection. The authors will not discuss the radiologic evaluation of the child who has had a previous renal infection, in whom cortical scarring or reflux nephropathy is a possibility; these are different clinical problems and require different diagnostic evaluation

Aging-associated kidney disease is usually considered a degenerative process associated with aging. Recently, it has been shown that animals can produce fructose endogenously, and that this can be a mechanism for causing kidney damage in diabetic nephropathy and in association with recurrent dehydration. We therefore hypothesized that low-level metabolism of endogenous fructose might play a role in aging-associated kidney disease. Wild-type and fructokinase knockout mice were fed a normal diet for 2 yr that had minimal (renal injury was amplified by provision of high-salt diet for 3 wk, as noted by the presence of glomerular hypertrophy, mesangial matrix expansion, and alpha smooth muscle actin expression, and with segmental thrombi. Fructokinase knockout mice were protected from renal injury both at baseline and after high salt intake (3 wk) compared with wild-type mice. This was associated with higher levels of active (phosphorylated serine 1177) endothelial nitric oxide synthase in their kidneys. These studies suggest that aging-associated renal disease might be due to activation of specific metabolic pathways that could theoretically be targeted therapeutically, and raise the hypothesis that aging-associated renal injury may represent a disease process as opposed to normal age-related degeneration.

Recognition of early stage of diabetic kidney disease, under common practice using biomarkers, namely microalbuminuria, serum creatinine level above 1 mg/dL and accepted definition of diabetic kidney disease associated with creatinine clearance value below 60 mL/min/1.73 m 2 , is unlikely. This would lead to delay treatment associated with therapeutic resistance to vasodilator due to a defective vascular homoeostasis. Other alternative biomarkers related to the state of microalbuminuria is not sensitive to screen for early diabetic kidney disease (stages I, II). In this regard, a better diagnostic markers to serve for this purpose are creatinine clearance, fractional excretion of magnesium (FE Mg), cystatin C. Recently, renal microvascular disease and renal ischemia have been demonstrated to correlate indirectly with the development of diabetic kidney disease and its function. Among these are angiogenic and anti-angiogenic factors, namely VEGF, VEGF receptors, angiopoietins and endostatin. With respect to therapeutic prevention, implementation of treatment at early stage of diabetic and nondiabetic kidney disease is able to restore renal perfusion and function.

Paraprotein–Related Kidney Disease: Diagnosing and Treating Monoclonal Gammopathy of Renal Significance

Rosner, Mitchell H.; Edeani, Amaka; Yanagita, Motoko; Glezerman, Ilya G.

2016-01-01

Paraprotein–related kidney disease represents a complex group of diseases caused by an abnormal paraprotein secreted by a clone of B cells. The disease manifestations range from tubulopathies, such as the Fanconi syndrome, to a spectrum of glomerular diseases that can present with varying degrees of proteinuria and renal dysfunction. Diagnosis of these diseases can be challenging because of the wide range of manifestations as well as the relatively common finding of a serum paraprotein, especially in elderly patients. Thus, renal biopsy along with detailed hematologic workup is essential to link the presence of the paraprotein to the associated renal disease. Recent advances in treatment with more effective and targeted chemotherapies, as well as stem cell transplantation, have improved the renal and overall prognosis for many of these disorders.

Full Text Available Abstract Background Osteoporosis affects over 200 million people worldwide, and represents a significant cost burden. Although guidelines are available for best practice in osteoporosis, evidence indicates that patients are not receiving appropriate diagnostic testing or treatment according to guidelines. The use of clinical decision support systems (CDSSs may be one solution because they can facilitate knowledge translation by providing high-quality evidence at the point of care. Findings from a systematic review of osteoporosis interventions and consultation with clinical and human factors engineering experts were used to develop a conceptual model of an osteoporosis tool. We conducted a qualitative study of focus groups to better understand physicians' perceptions of CDSSs and to transform the conceptual osteoporosis tool into a functional prototype that can support clinical decision making in osteoporosis disease management at the point of care. Methods The conceptual design of the osteoporosis tool was tested in 4 progressive focus groups with family physicians and general internists. An iterative strategy was used to qualitatively explore the experiences of physicians with CDSSs; and to find out what features, functions, and evidence should be included in a working prototype. Focus groups were conducted using a semi-structured interview guide using an iterative process where results of the first focus group informed changes to the questions for subsequent focus groups and to the conceptual tool design. Transcripts were transcribed verbatim and analyzed using grounded theory methodology. Results Of the 3 broad categories of themes that were identified, major barriers related to the accuracy and feasibility of extracting bone mineral density test results and medications from the risk assessment questionnaire; using an electronic input device such as a Tablet PC in the waiting room; and the importance of including well-balanced information in

The type of nephrolithiasis was determined in 45 cases and etiology in 42. The treatment and evolution of stone disease and patient’s survival were studied.Results: The overall proportion of nephrolithiasis related ESRD was 0.63%. The mean age was 48.4 years. Infection stones (struvite accounted for 40%, calcium stones, 26.67% (primary hyperparathyroidism:15.56%; familial hypercalciuria: 4.44%, unknown etiology: 6.66%, primary hyperoxaluria type 1, 17.78% and uric acid lithiasis in 15.56% of cases. The mean delay of the evolution of the stone renal disease to chronic renal failure was 85.8 months. The feminine gender, obesity and elevated alkaline phosphatases >128 IU/L were significantly correlated with fast evolution of ESRD. The median evolution to ESRD was 12 months. The normal body mass index (BMI, medical treatment of stone and primary hyperoxaluria type 1 were correlated with fast evolution to ESRD. All patients were treated by hemodialysis during a mean evolution of 60 months. Sixteen patients died. The patient's survival rate at 1, 3 and 5 years was 97.6, 92.8 and 69% respectively. Hypocalcemia, cardiopathy and normal calcium-phosphate product were significantly correlated with lower survival rate.Conclusion: Severe forms of nephrolithiasis remain an underestimated cause of

A young female with sickle cell disease was treated for biopsy-proven IgA nephropathy. Serum creatinine levels resolved to normal range, but a year later, she presented with oedema, hypertension and acute renal failure. A repeat renal biopsy showed acute-on-chronic thrombotic microangiopathy (TMA). We suggest that circulating microparticles could be a pathophysiological link between sickle cell disease and the development of renal TMA. This case emphasizes the importance of a further biopsy for acutely declining renal function, even when a definite diagnosis has been made from a previous biopsy. PMID:25949348

Osteoporosis affects over 200 million people worldwide at a high cost to healthcare systems, yet gaps in management still exist. In response, we developed a multi-component osteoporosis knowledge translation (Op-KT) tool involving a patient-initiated risk assessment questionnaire (RAQ), which generates individualized best practice recommendations for physicians and customized education for patients at the point of care. The objective of this study was to evaluate the effectiveness of the Op-KT tool for appropriate disease management by physicians. The Op-KT tool was evaluated using an interrupted time series design. This involved multiple assessments of the outcomes 12 months before (baseline) and 12 months after tool implementation (52 data points in total). Inclusion criteria were family physicians and their patients at risk for osteoporosis (women aged ≥ 50 years, men aged ≥ 65 years). Primary outcomes were the initiation of appropriate osteoporosis screening and treatment. Analyses included segmented linear regression modeling and analysis of variance. The Op-KT tool was implemented in three family practices in Ontario, Canada representing 5 family physicians with 2840 age eligible patients (mean age 67 years; 76% women). Time series regression models showed an overall increase from baseline in the initiation of screening (3.4%; P management addressed by their physician. Study limitations included the inherent susceptibility of our design compared with a randomized trial. The multicomponent Op-KT tool significantly increased osteoporosis investigations in three family practices, and highlights its potential to facilitate patient self-management. Next steps include wider implementation and evaluation of the tool in primary care.

Full Text Available Diabetic nephropathy (DN is one of the major complications of type 2 diabetes mellitus (T2DM. The diagnosis of DN is mostly clinical. Kidney biopsy is indicated only if nondiabetic renal disease (NDRD is suspected. This study is aimed to assess the prevalence of NDRD and to determine predictor and prognostic factors of DN, NDRD. It was a retrospective analytic study including T2DM patients in whom renal biopsies were performed at our department from 1988 to 2014. Seventy-five patients were included. Mean age was 52.7 years with sex ratio at 1.56. Renal biopsy findings were isolated NDRD in 33 cases, NDRD superimposed on DN in 24 cases, and isolated DN in 18 cases. Most common NDRD found were focal segmental glomerulosclerosis (21% and membranous nephropathy (19%. Multivariate analysis showed that the absence of ischemic heart disease [odds ratio (OR = 0.178, 95% confidence interval (CI = 0.041–0.762], absence of peripheral vascular disease (OR = 0.173, 95% CI = 0.045–0.669, and presence of hematuria (OR = 7.200, 95%CI = 0.886–58.531 were independent predictors of NDRD. 24 patients reached end-stage renal disease 55% in DN group, 16% in DN associated to NDRD group, and 30% in NDRD group. The prevalence of NDRD found in our study confirmed usefulness of renal biopsy in patients with T2DM, especially in those without degenerative complications, hypertension, and insulin therapy.

How should clinicians manage osteoporosis in ankylosing spondylitis?

Osteoporosis is a common complication of AS, with an incidence between 18.7% and 62%. The prevalence of osteoporosis is greater in males, and increases with increasing patient age and disease duration. Osteoporosis is also more common in patients with syndesmophytes, cervical fusion, and peripheral joint involvement. These variables are not all independent, as they may be indicators of disease duration. Osteoporosis in patients with AS is largely confined to the axial skeleton, in contrast to the pattern of osteoporosis seen in rheumatoid arthritis. BMD at the lumbar spine and femoral neck may be severely reduced, while most studies indicate that carpal and radial BMD remain within normal limits. The development of syndesmophytes in late AS can lead to difficulties in the use of DEXA scanning to determine lumbar BMD, as the extraspinal bone may obscure osteoporotic vertebrae. Under these circumstances more accurate assessment of lumbar BMD, and one that correlates better with femoral neck BMD, may be obtained by quantitative CT scanning or DEXA scanning of the lateral aspect of the L3 vertebra. Osteoporosis in AS significantly increases the risk of vertebral compression fractures within 5 years of the diagnosis of AS. The risk of a vertebral compression fracture occurring over a 30 year period following the diagnosis of AS is 14%, compared to 3.4% for population controls. In patients with vertebral osteoporosis relatively minor trauma, such as slipping, can lead to spinal fracture and dislocatior with subsequent damage to the spinal cord. There is a higher incidence of spinal cord injury following spinal fracture dislocations in patients with AS, and the resulting neurological deficit can range from mild sensory loss to complete paraplegia. Cytokines such as TNF-alpha and IL-6 may play an important part in the pathogenesis of osteoporosis in early AS, and IL-6 levels have been correlated with markers of disease activity and severity. In late AS, mechanical factors

The appearance of proteinuria in an insulin-dependent diabetic patient is an ominous sign. Proteinuria heralds the presence of diabetic nephropathy and early death, or chronic renal failure requiring dialysis or transplantation, in 50% of patients. The pathogenesis of diabetic nephropathy is unknown. Adequate insulin administration is the most important preventive measure. Hypertension, if present, should be aggressively treated to delay progression of renal disease. Good nutrition, prompt treatment of urinary tract infections, and caution in the use of radiocontrast agents are other important preventive measures. Hemodialysis, peritoneal dialysis, and transplantation are options for patients with end-stage renal disease. No matter which is selected, the patient may still have multiple amputations, blindness, congestive heart failure, infections, and uncontrolled glycemia. Advancements are being made, however, that promise a better future for insulin-dependent diabetics.

The Critical Role of Estrogen in Menopausal Osteoporosis

Full Text Available Osteoporosis is a bone disorder, which causes a reduction in the mass and density of bone tissue, and implants a greater possibility for skeletal fractures to occur. This bone disease is especially relevant for women suffering from menopause. Due to this general prevalence, osteoporosis requires continual intervention in the pharmacological and medicinal industry for better treatment alternatives for patients. A focal point for many scientific research studies for osteoporosis has been estrogen. As a hormone, estrogen exhibits a fluctuating capacity in the woman's body, and this has been proclaimed to be a qualifying explanation as to why women develop osteoporosis after menopause. The purpose of this paper is to interpret estrogen's capacity to treat menopausal osteoporosis. Thus, in this article, estrogen’s significance in bone health and different forms, derivatives, and the combinations of estrogen is examined in terms of efficiency in treating osteoporosis.

The present study examined the effects of benazepril, an angiotensin-converting enzyme inhibitor, on the progression of renal insufficiency in patients with non-diabetic renal disease. Fifteen patients with non-diabetic renal disease whose serum creatinine (Cr) ranged from 1.5 to 3.0 mg/dL were given either benazepril (2.5-5 mg) or placebo once daily for 1 year in a random crossover manner. In both periods, antihypertensive medications were increased if blood pressure was greater than 130/85 mmHg. Blood sampling and urinalysis were performed bimonthly throughout the study period. Blood pressure was similar when comparing the benazepril and the placebo periods (128+/-12/83+/-6 vs 129+/-10/83+/-7 mmHg). Serum Cr significantly increased from 1.62+/-0.18 to 1.72+/-0.30 mg/dL (P=0.036) during the placebo period, while there was no statistically significant increase in serum Cr during the benazepril period (from 1.67+/-0.17 to 1.71+/-0.27 mg/dL). The slope of decrease of the reciprocal of serum Cr was steeper in the placebo period than in the benazepril period (-0.073+/-0.067 vs-0.025+/-0.096/year, P=0.014). Urinary protein excretion was lower during the benazepril period than during the placebo period (0.57+/-0.60 vs 1.00+/-0.85 g/gCr, P=0.006). Serum K was significantly higher in the benazepril period than in the placebo period (4.4+/-0.5 vs 4.2+/-0.5 mEq/L, Pbenazepril therapy as a result of hyperkalemia. Long-term benazepril treatment decreased the progression of renal dysfunction in patients with non-diabetic renal disease by a mechanism that is independent of blood pressure reduction.

The sustainability of captive cheetah populations is limited by high mortality due to chronic renal disease. This necropsy study, conducted on 243 captive cheetahs from one institution, investigated the relationships between focal palatine erosions, gastritis, enterocolitis, glomerulosclerosis, chronic renal infarcts, renal cortical and medullary fibrosis, and renal medullary amyloidosis at death. Associations between the individual renal lesions and death due to chronic renal disease and comparisons of lesion prevalence between captive bred and wild born and between normal and king coated cheetahs were also assessed. All lesions were significantly positively correlated with age at death. Renal medullary fibrosis was the only lesion associated with the likelihood of death being due to chronic renal disease, and cheetahs with this lesion were younger, on average, than cheetahs with other renal lesions. Alimentary tract lesions were not associated with amyloidosis. All lesions, except for palatine erosions, were more common in wild born than in captive bred cheetahs; the former were older at death than the latter. Having a king coat had no clear effect on disease prevalence. These results suggest that age and renal medullary fibrosis are the primary factors influencing the pathogenesis of chronic renal disease in captive cheetahs. Apart from amyloidosis, these findings are analogous to those described in chronic renal disease in domestic cats, which is postulated to result primarily from repetitive hypoxic injury of renal tubules, mediated by age and stress. Cheetahs may be particularly susceptible to acute renal tubular injury due to their propensity for stress and their extended life span in captivity, as well as their adaptation for fecundity (rather than longevity) and adrenaline-mediated high speed prey chases. The presence of chronic renal disease in subadult cheetahs suggests that prevention, identification and mitigation of stress are critical to the

Renal resistive index (RRI) measured by Doppler ultrasonography is associated with cardiovascular events and mortality in hypertensive, diabetic, and elderly patients. We studied the factors associated with high RRI (≥0.70) and its associations with mortality in chronic kidney disease patients without renal artery stenosis. We included 1962 patients with an estimated glomerular filtration rate of 15 to 59 mL/min per 1.73 m(2) who also had RRI measured (January 1, 2005, to October 2011) from an existing chronic kidney disease registry. Participants with renal artery stenosis (60%-99% or renal artery occlusion) were excluded. Multivariable logistic regression model was used to study factors associated with high RRI (≥0.70), and its association with mortality was studied using Kaplan-Meier plots and Cox proportional hazards model. Hypertension was prevalent in >90% of the patients. In the multivariable logistic regression, older age, female sex, diabetes mellitus, coronary artery disease, peripheral vascular disease, higher systolic blood pressure, and the use of β blockers were associated with higher odds of having RRI≥0.70. During a median follow-up of 2.2 years, 428 patients died. After adjusting for covariates, RRI≥0.70 was associated with increased mortality (adjusted hazard ratio, 1.29; 95% confidence interval, 1.02-1.65; Pchronic kidney disease. Noncardiovascular/non-malignancy-related deaths were higher in those with RRI≥0.70. RRI≥0.70 is associated with higher mortality in hypertensive chronic kidney disease patients without clinically significant renal artery stenosis after accounting for other significant risk factors. Its evaluation may allow early identification of those who are at risk thereby potentially preventing or delaying adverse outcomes. © 2015 American Heart Association, Inc.

Osteoporosis is a chronic disease characterized by a decrease in bone mineral density (BMD) and corruption of the microarchitectural structure of bone tissue. It was investigated whether methylprednisolone had a favorable effect on osteoporotic bone tissue in Oophorectomy induced osteoporotic rats whose endogenous adrenaline levels are suppressed with metyrosine. Bone Mineral Density, number of osteoblast-osteoclast, bone osteocalcin levels and alkaline phosphatase (ALP) measurements were performed. Obtained results were compared with that of alendronate. Oophorectomy induced osteoporosis was exacerbated by methylprednisolone. Alentronate prevented ovariectomised induced osteoporosis, but it couldn't prevent methylprednisolone +ovariectomised induced osteoporosis in rats. Combined treatment with methylprednisolon and metyrosine was the best treatment for preventing osteoporosis but metyrosine alone couldn't prevent osteoporosis in ovariectomised rats.

Full Text Available Adult coeliac disease commonly presents without classical symptoms as chronic diarrhea and weight loss. We describe the case of a 31-year-old woman with persistent life-threatening hypokalemia, acute renal failure, and acute quadriplegia due to diarrhea that had continued for one month. Although there are cases of coeliac disease diagnosed with hypokalemic rhabdomyolysis in the literature, none of the cases developed acute renal failure. This is the first case in the literature diagnosed with acute renal failure due to hypokalemic rhabdomyolysis as a presentation of coeliac disease. In acute renal failure cases that present with hypokalemic rhabdomyolysis due to severe diarrhea, coeliac disease should be considered as a differential diagnosis despite the negative antigliadin IgA antibody.

Osteoporosis as a chronic disease, affecting especially women in postmenopausal age, is an important, social and economic health problem especially of women of today's world. The aim of the study was to assess the level of knowledge of women in the peri- and postmenopausal period about the prevention of osteoporosis and show the influence of chosen risk factors on the level of this knowledge. A group of 300 women aged 45-65, being patients of healthcare centres in Chełm, Lublin and Zamość (Lublin voivodeship, south-eastern Poland) were included in the study. The purposive sampling was used. Osteoporosis Knowledge Test (OKT) 2011 was the research tool. Gathered material was subjected to descriptive and statistical analysis. Tukey's test, t-student test and variance analysis (ANOVA) were all applied. An accepted p materiality level was level of knowledge about the role of physical activity in the prevention of osteoporosis (M = 13.93) and a low level of knowledge about well-balanced diet rich in calcium (M = 9.77). The knowledge about risk factors, screening and treatment remained on the average level (M = 8.00). An influence of socio-demographic factors on the level of knowledge was shown. Also some behaviours, associated with the lifestyle indeed influenced the level of this knowledge. Professional educational programs on osteoporosis should be implemented in the population of Polish peri- and postmenopausal women.

Education is ideal for osteoporosis because many risk factors are modifiable. However, the efficacy of shortened education courses compared to a standard 4 week course for improving osteoporosis knowledge and healthy behaviours is not known. This study aimed to assess whether education changed knowledge and healthy behaviours over 3 months of follow-up; and whether changes in these outcomes were different between participants receiving the different education courses. Adults aged ≥ 50 years presenting to Emergency with mild to moderate trauma fractures received either the Osteoporosis Prevention and Self-Management Course (OPSMC) (4 × 2.5 h) (n = 75) or a one-session course (1 × 2.5 h) (n = 71) in a non-randomised prospective study with single-blinded allocation. Participants completed questionnaires measuring osteoporosis knowledge, dietary calcium, physical activity, calcium and exercise self-efficacy, and osteoporosis medications at baseline and 3 months. Data were analysed using mixed models and GEE regression models. Osteoporosis knowledge and calcium from food (% of RDI) increased from baseline to 3 months in both groups (P osteoporosis medications increased between baseline and 3 months in the OPSMC group while decreasing in the one-session group (P = 0.039). There were no differences between the groups or over time in physical activity, calcium or exercise self-efficacy. Osteoporosis education (either the OPSMC or the one-session course) improved osteoporosis knowledge and calcium intake after 3 months. Participants attending the OPSMC maintained medication compliance. We were unable to determine other differences between the courses. This study confirms the value of osteoporosis education for improving osteoporosis knowledge. © 2011 The Authors.

On the basis of studies with hepatorenal syndrome, it is widely regarded that renal function is impacted in chronic liver disease (CLD). Therefore, we investigated renal function in children with CLD. In a retrospective study of 277 children with CLD, renal function was investigated as glomerular filtration rate (GFR) and effective renal plasma flow (ERPF), measured as clearance of inulin and para-amino hippuric acid or clearance of iohexol. The data were analyzed with regard to different subgroups of liver disease and to the grade of damage. Hyperfiltration (>+2 SD of controls) was found in the subgroups of progressive familial intrahepatic cholestasis (44%), glycogenosis (75%), and acute fulminant liver failure (60%). Patients with biliary atresia, most other patients with metabolic disease and intrahepatic cholestasis, and those with vascular anomalies and cryptogenic cirrhosis had normal renal function. Decreased renal function was found in patients with Alagille's syndrome (64% < -2 SD). Increased GFR and ERPF was found in patients with elevated transaminases, low prothrombin level, high bile acid concentration, and high aspartate-aminotransferase-to-platelet ratio. Most children with CLD had surprisingly well preserved renal function and certain groups had even hyperfiltration. The finding that children with decompensated liver disease and ongoing liver failure had stable kidney function suggests that no prognostic markers of threatening hepatorenal syndrome were at hand. Moreover, estimation of GFR based on serum creatinine fails to reveal hyperfiltration.

Renal expression of FGF23 in progressive renal disease of diabetes and the effect of ACE inhibitor.

Directory of Open Access Journals (Sweden)

Cristina Zanchi

Full Text Available Fibroblast growth factor 23 (FGF23 is a phosphaturic hormone mainly produced by bone that acts in the kidney through FGF receptors and Klotho. Here we investigated whether the kidney was an additional source of FGF23 during renal disease using a model of type 2 diabetic nephropathy. Renal expression of FGF23 and Klotho was assessed in Zucker diabetic fatty (ZDF and control lean rats at 2, 4, 6, 8 months of age. To evaluate whether the renoprotective effect of angiotensin converting enzyme (ACE inhibitor in this model was associated with changes in FGF23 and Klotho, ZDF rats received ramipril from 4, when proteinuric, to 8 months of age. FGF23 mRNA was not detectable in the kidney of lean rats, nor of ZDF rats at 2 months of age. FGF23 became measurable in the kidney of diabetic rats at 4 months and significantly increased thereafter. FGF23 protein localized in proximal and distal tubules. Renal Klotho mRNA and protein decreased during time in ZDF rats. As renal disease progressed, serum phosphate levels increased in parallel with decline of fractional phosphorus excretion. Ramipril limited proteinuria and renal injury, attenuated renal FGF23 upregulation and ameliorated Klotho expression. Ramipril normalized serum phosphate levels and tended to increase fractional phosphorus excretion. These data indicate that during progressive renal disease the kidney is a site of FGF23 production which is limited by ACE inhibition. Interfering pharmacologically with the delicate balance of FGF23 and phosphorus in diabetes may have implications in clinics.

The purpose of our study was to describe the clinical and radiological manifestations of tuberculosis in patients with end-stage renal disease. The medical records, chest radiographs, and CT scans of 42 patients with tuberculosis among 871 consecutive patients with end-stage renal disease were reviewed. Patterns of initial chest radiographs were categorized as primary, postprimary, miliary, or atypical, according to the predominant radiologic findings. Chest radiographs and CT scans revealed pulmonary tuberculosis in 28 patients and extrapulmonary tuberculosis in 15. The pattern of chest radiographs indicative of pulmonary tuberculosis was primary in 12 cases, postprimary in 11, miliary in one, demonstrated atypical infiltrates in three, and was normal in one. Tuberculosis involved the extrathoracic lymph nodes in six cases, the peritoneum in four, the spine in three, and the bone marrow in two. The primary pattern, seen in 12 patients, manifested as pleural effusion or segmental consolidation, and in ten of the twelve the former was dominant. The radiological pattern of pulmonary tuberculosis in end-stage renal disease is often primary, and extrapulmonary involvement is frequent

Full Text Available Animal studies suggest that renal tissue hypoxia plays an important role in the development of renal damage in hypertension and renal diseases, yet human data were scarce due to the lack of noninvasive methods. Over the last decade, blood oxygenation level-dependent magnetic resonance imaging (BOLD-MRI, detecting deoxyhemoglobin in hypoxic renal tissue, has become a powerful tool to assess kidney oxygenation noninvasively in humans. This paper provides an overview of BOLD-MRI studies performed in patients suffering from essential hypertension or chronic kidney disease (CKD. In line with animal studies, acute changes in cortical and medullary oxygenation have been observed after the administration of medication (furosemide, blockers of the renin-angiotensin system or alterations in sodium intake in these patient groups, underlining the important role of renal sodium handling in kidney oxygenation. In contrast, no BOLD-MRI studies have convincingly demonstrated that renal oxygenation is chronically reduced in essential hypertension or in CKD or chronically altered after long-term medication intake. More studies are required to clarify this discrepancy and to further unravel the role of renal oxygenation in the development and progression of essential hypertension and CKD in humans.

Full Text Available Introduction. Cardiovascular (CV diseases and bone fractures due to osteoporosis are the leading causes of death in the elderly. Objective. The aim of this study was to demonstrate a correlation between the overall risk for CV events, and low bone density in postmenopausal women, and its impact on the incidence of serious CV events. Methods. Our prospective study involved 300 postmenopausal women. All the examinees were divided into three groups based on their measured bone density: Group I - 84 examinees with osteoporosis; Group II - 115 examinees with osteopenia; and Group III - 101 examinees with normal bone density. In all examinees the overall ten-year risk for a fatal CV event was calculated using the SCORE system tables. Results. After a 36-month follow-up, CV events occurred in 19 (6.3% examinees. Significant differences in the incidence of CV events were demonstrated between the patients with osteoporosis, osteopenia, and normal bone density (χ2=28.7; p<0.001, as well as between those with a high and low CV risk (χ2=22.6; p<0.001. Multivariate logistic regression analysis showed that smoking (OR: 2.23; 95% CI: 1.02 to 6.19; p=0.035, and increase of overall CV score (OR: 1.36; 95% CI: 1.17 to 1.58; p<0.001 are associated with increased CV event risk, while the increase of T score value is associated with decreased risk of CV event (OR: 0.42; 95% CI: 0.25 to 0.73; p=0.002. Conclusion. Measurement of bone density with a standard assessment of the total CV risk could be useful for selecting women who need intensive prevention and treatment of atherosclerosis.

In this article, techniques of ASL will be explained and challenges of renal ASL will be emphasized. In addition, examples for clinical application of ASL for diagnosis of renal disease and renal allograft pathology will be given.

Antioxidative vitamines for prevention of cardiovascular disease for patients after renal transplantation and patients with chronic renal failure

Directory of Open Access Journals (Sweden)

Wasem, Jürgen

2006-07-01

Full Text Available Introduction: The mortality from cardiovascular disease in patients with chronic renal failure is much higher than in the general population. In particular, patients with chronic renal failure with replacement therapies (dialysis patients and patients with renal transplantation show both increased traditional risk factors and risk factors due to the dysfunction of the renal system. In combination with necessary medication for renal insufficiency oxidative stress is elevated. Progression of atherosclerosis is promoted due to increased oxidation of lipids and endothelium damage. This link between lipid oxidation and artherogenesis provides the rationale for the supposed beneficial effect of supplementation with antioxidative vitamins (vitamin A, C and E. Such an effect could not be demonstrated for patients with a history of cardiovascular disease and without kidney diseases. However, in high risk patients with chronic renal failure and renal replacement therapies this could be different. Objectives: The objective of this systematic literature review was to assess the clinical effectiveness and cost-effectiveness of supplementation with antioxidative vitamins A, C or E to reduce cardiovascular events in patients with chronic kidney diseases, dialysis-requiring patients and patients after a renal transplantation with or without cardiovascular diseases. Methods: A systematic literature review was conducted with documented search and selection of the literature, using a priori defined inclusion and exclusion criteria as well as a documented extraction and assessment of the literature according to the methods of evidence-based medicine. Results: 21 publications met the inclusion criteria for the evaluation of clinical effectiveness. No study could be identified for the economic evaluation. Two studies (four publications analysed the effect of oral supplementation on the secondary prevention of clinical cardiovascular endpoints. Studies analysing the

Diabetic kidney disease (DKD) is the most common cause of severe renal disease, and few treatment options are available today that prevent the progressive loss of renal function. DKD is characterized by altered glomerular filtration and proteinuria. A common observation in DKD is the presence of renal steatosis, but the mechanism(s) underlying this observation and to what extent they contribute to disease progression are unknown. Vascular endothelial growth factor B (VEGF-B) controls muscle lipid accumulation through regulation of endothelial fatty acid transport. Here, we demonstrate in experimental mouse models of DKD that renal VEGF-B expression correlates with the severity of disease. Inhibiting VEGF-B signaling in DKD mouse models reduces renal lipotoxicity, re-sensitizes podocytes to insulin signaling, inhibits the development of DKD-associated pathologies, and prevents renal dysfunction. Further, we show that elevated VEGF-B levels are found in patients with DKD, suggesting that VEGF-B antagonism represents a novel approach to treat DKD. Copyright © 2017 Elsevier Inc.

Sirtuins are members of the Sir2 (silent information regulator 2) family, a group of class III deacetylases. Mammals have seven different sirtuins, SIRT1-SIRT7. Among them, SIRT1, SIRT3 and SIRT6 are induced by calorie restriction conditions and are considered anti-aging molecules. SIRT1 has been the most extensively studied. SIRT1 deacetylates target proteins using the coenzyme NAD+ and is therefore linked to cellular energy metabolism and the redox state through multiple signalling and survival pathways. SIRT1 deficiency under various stress conditions, such as metabolic or oxidative stress or hypoxia, is implicated in the pathophysiologies of age-related diseases including diabetes, cardiovascular diseases, neurodegenerative disorders and renal diseases. In the kidneys, SIRT1 may inhibit renal cell apoptosis, inflammation and fibrosis, and may regulate lipid metabolism, autophagy, blood pressure and sodium balance. Therefore the activation of SIRT1 in the kidney may be a new therapeutic target to increase resistance to many causal factors in the development of renal diseases, including diabetic nephropathy. In addition, SIRT3 and SIRT6 are implicated in age-related disorders or longevity. In the present review, we discuss the protective functions of sirtuins and the association of sirtuins with the pathophysiology of renal diseases, including diabetic nephropathy.

Renal function trajectory is more important than chronic kidney disease stage for managing patients with chronic kidney disease.

Science.gov (United States)

Rosansky, Steven J

2012-01-01

Management of patients with chronic kidney disease (CKD) emphasizes a current level of function as calculated from the modification of diet in renal disease glomerulofiltration rate equations (eGFR) and proteinuria for staging of CKD. Change in a patient's eGFR over time (renal function trajectory) is an additional and potentially more important consideration in deciding which patients will progress to the point where they will require renal replacement therapy (RRT). Many patients with CKD 3-5 have stable renal function for years. Proteinuria/albuminuria is a primary determinant of renal trajectory which may be slowed by medications that decrease proteinuria and/or aggressively lower blood pressure. A renal trajectory of >3 ml/min/1.73 m(2)/year may relate to a need for closer renal follow-up and increased morbidity and mortality. Additional CKD population-based studies need to examine the relationship of renal trajectory to: baseline renal function; acute kidney injury episodes; age, race, sex and primary etiologies of renal disease; blood pressure control and therapies; dietary protein intake; blood glucose control in diabetics and the competitive risk of death versus the requirement for renal replacement therapy. In the elderly CKD 4 population with significant comorbidities and slow decline in renal function, the likelihood of death prior to the need for RRT should be considered before placing AV access for dialysis. Prediction models of renal progression must account for the competitive risk of death as well as stable or improved renal function to be clinically useful. Copyright © 2012 S. Karger AG, Basel.

The Latin American Dialysis and Renal Transplant Registry (RLADTR) was founded in 1991; it collects data from 20 countries which are members of Sociedad Latinoamericana de Nefrología e Hipertension. This paper presents the results corresponding to the year 2010. This study is an annual survey requesting data on incident and prevalent patients undergoing renal replacement treatment (RRT) in all modalities: hemodialysis (HD), peritoneal dialysis (PD) and living with a functioning graft (LFG), etc. Prevalence and incidence were compared with previous years. The type of renal replacement therapy was analyzed, with special emphasis on PD and transplant (Tx). These variables were correlated with the gross national income (GNI) and the life expectancy at birth. Twenty countries participed in the surveys, covering 99% of the Latin American. The prevalence of end stage renal disease (ESRD) under RRT in Latin America (LA) increased from 119 patients per million population (pmp) in 1991 to 660 pmp in 2010 (HD 413 pmp, PD 135 pmp and LFG 111 pmp). HD proportionally increased more than PD, and Tx HD continues to be the treatment of choice in the region (75%). The kidney Tx rate increased from 3.7 pmp in 1987 to 6.9 pmp in 1991 and to 19.1 in 2010. The total number of Tx's in 2010 was 10 397, with 58% deceased donors. The total RRT prevalence correlated positively with GNI ( r 2 0.86; P chronic kidney disease (CKD) and its associated risk factors. PD is still an underutilized strategy for RRT in the region. Even though renal Tx is feasible, its growth rate is still not as fast as it should be in order to compensate for the increased prevalence of patients on waiting lists. Diagnostic and prevention programs for hypertension and diabetes, appropriate policies promoting the expansion of PD and organ procurement as well as transplantation as cost-effective forms of RRT are needed in the region. Regional cooperation among Latin American countries, allowing the more developed to

Recombinant human parathyroid hormone related protein 1-34 and 1-84 and their roles in osteoporosis treatment.

Full Text Available Osteoporosis is a common disorder characterized by compromised bone strength that predisposes patients to increased fracture risk. Parathyroid hormone related protein (PTHrP is one of the candidates for clinical osteoporosis treatment. In this study, GST Gene Fusion System was used to express recombinant human PTHrP (hPTHrP 1-34 and 1-84. To determine whether the recombinant hPTHrP1-34 and 1-84 can enhance renal calcium reabsorption and promote bone formation, we examined effects of recombinant hPTHrP1-34 and 1-84 on osteogenic lineage commitment in a primary bone marrow cell culture system and on osteoporosis treatment. Results revealed that both of recombinant hPTHrP1-34 and 1-84 increased colony formation and osteogenic cell differentiation and mineralization in vitro; however, the effect of recombinant hPTHrP1-84 is a little stronger than that of hPTHrP1-34. Next, ovariectomy was used to construct osteoporosis animal model (OVX to test activities of these two recombinants in vivo. HPTHrP1-84 administration elevated serum calcium by up-regulating the expression of renal calcium transporters, which resulted in stimulation of osteoblastic bone formation. These factors contributed to augmented bone mass in hPTHrP1-84 treated OVX mice but did not affect bone resorption. There was no obvious bone mass alteration in hPTHrP1-34 treated OVX mice, which may be, at least partly, associated with shorter half-life of hPTHrP1-34 compared to hPTHrP1-84 in vivo. This study implies that recombinant hPTHrP1-84 is more effective than hPTHrP1-34 to enhance renal calcium reabsorption and to stimulate bone formation in vivo.

One hundred and twelve cases of renal diseases were studied by computed tomography (CT) using EMI 5005/12. Of them, 60 were examined by both CT and renal scintigraphy, and comparatively evaluated. The CT units were checked before and after the contrast enhancement. Renal scintigrams were obtained by gamma cameras (PHO/GAMMA HP 6406, PHO/GAMMA LFOV) using 99 M Tc-DMSA. CT was especially useful in diagnosing the renal cysts and the hydronephrosis. Cysts in other organs (liver, spleen and pancreas) were simultaneously ascertained in polycystic diseases. CT was not helpful in diagnosing nephritis and diabetic nephropathy. Floating kidney and horse-shoe kidney were difficult to diagnose with CT. The renal scintigram was the reflection of the renal function, and was relatively more useful than CT in diagnosing horse-shoe kidney, floating kidney and nephritis, while it was not useful for non-functioning kidneys.

ESWL is now widely used for the treatment of renal stone disease. Although ESWL has many advantages for patients' quality of life, few reports have demonstrated the long-term outcomes of the alterations of renal morphology after ESWL. We reported renal scarring after ESWL monotherapy in patients with renal calyceal stones. In this study, we evaluated a large series of patients' cohort treated at our institution, and assessed the causal effect of ESWL on the late occurrence of renal scar formation. ESWL was performed with EDAP (LT-01,02) that generates shock wave energy by piezoelectric discharge. We analyzed the records of 285 kidneys treated between Dec. 1986 and Nov. 1998. Renal scarring was noted in 44 kidneys and not in 241 kidneys with periodical ultrasonography. We compared the backgrounds of the two groups using chi-square or non-parametric analysis. The Kaplan-Meier method and Cox regression model determined the analysis of renal scar formation. Univariate and multiple regression analysis revealed that the total amount of ESWL emission and hyperuricemia independently affected the probability of renal scar formation. Over-emission of ESWL (over 10,000 shots) must be care for the prevention of renal scarring in patients with renal calyceal calculi, especially when associated with hyperuricemia. After ESWL, periodical checkups with ultrasonography will provide useful information for the clinical diagnosis of renal scarring.

Escherichia coli Shiga Toxin Mechanisms of Action in Renal Disease

2010-12-01

Full Text Available Shiga toxin-producing Escherichia coli is a contaminant of food and water that in humans causes a diarrheal prodrome followed by more severe disease of the kidneys and an array of symptoms of the central nervous system. The systemic disease is a complex referred to as diarrhea-associated hemolytic uremic syndrome (D+HUS. D+HUS is characterized by thrombocytopenia, microangiopathic hemolytic anemia, and acute renal failure. This review focuses on the renal aspects of D+HUS. Current knowledge of this renal disease is derived from a combination of human samples, animal models of D+HUS, and interaction of Shiga toxin with isolated renal cell types. Shiga toxin is a multi-subunit protein complex that binds to a glycosphingolipid receptor, Gb3, on select eukaryotic cell types. Location of Gb3 in the kidney is predictive of the sites of action of Shiga toxin. However, the toxin is cytotoxic to some, but not all cell types that express Gb3. It also can cause apoptosis or generate an inflammatory response in some cells. Together, this myriad of results is responsible for D+HUS disease.

Full Text Available Introduction: Diabetes mellitus (DM and osteoporotic fractures are major causes of mortality and morbidity in older subjects. Recent reports have revealed close association between fracture risk and DM types 1 and 2 (DM1 and DM2, respectively. Aim of this review is to highlight the importance of these diseases in the elderly and examine certain etiopathogenetic aspects of DM associated osteoporosis, which could be useful in management of diabetic patients. Materials and methods: We searched the Embase and PubMed databases using diabetes, osteoporosis, and bone mineral density (BMD as search terms and 1989-2009 as publication dates. Discussion: The risk of fractures seems to be increased in both types of DM although DM2 seems to be associated with normal-high BMDs compared with the normal population. This apparent paradox could reflect greater bone frailty in diabetic patients that are unrelated to adipose tissue, hyperinsulinemia, deposition of advanced glycosylation end products in collagen, reduced serum IGF-1 levels, hypercalciuria, renal failure, microangiopathy, and/or inflammation. Diabetic patients’ propensity to fall and multiple comorbidities might also explain their higher fracture rates. The effects of drugs that inhibit bone resorption in diabetic patients are probably similar to those obtained in nondiabetics although there is little information on this issue. In general, effective treatment of diabetes has positive effects on bone metabolism. Metformin acts directly on bone tissue, reducing AGE accumulation, and insulin has direct effects on osteoclast activity. In contrast, the thiazolidinediones seem to have negative effects since they orient mesenchymal progenitor cell differentiation toward adipose rather than bone tissue. Incretin therapy is a newer approach that appears to modify interactions between nutrition and bone turnover (e.g., postprandial suppression of bone resorption. Conclusions: Better understanding of how

Genetic and environmental factors are responsible for variations in the frequency of osteoporosis. Prevalence of osteoporosis in Mapuche women (native Chileans) is unknown. To assess the prevalence and risk factors for osteoporosis in Mapuche women. A random sample of 95 asymptomatic postmenopausal Mapuche females, stratified by age, was studied. Women with diseases or medications that could interfere with calcium metabolism were excluded. Spine and femoral neck bone mass density was determined using a Lunar DPX Alpha densitometer. Seventeen percent of women had normal bone mineral density in both spine and femoral neck. In the spine, 25.3% had a normal bone mineral density, 17.9% had osteopenia and 56.8% had osteoporosis. In the femoral neck, 34.7% had a normal bone mineral density, 57.9% had osteopenia, and 7.4% had osteoporosis. There was a positive correlation between bone mineral density and body mass index. Women with more than one hour per day of physical activity, had a significantly lower proportion of osteopenia or osteoporosis. No association between bone mineral density and parity or calcium intake, was observed. There is a high prevalence of osteopenia and osteoporosis among Mapuche women. Osteoporosis was associated with low body mass index.

The effect of Islamic fasting in Ramadan on osteoporosis

Full Text Available Osteoporosis is considered as one of the most common diseases that women face after their menopause and is caused by both genetic and environmental factors.  Dipeptidyl peptidase 4 (DPP-4 gene is one of the important genetic factors contributing in osteoporosis which has a direct and very important relationship with fasting. Fasting is one of the alternatives proved to reduce the DPP-4 level and activate the Dipeptidyl peptidase 4 inhibitors and so, prevent osteoporosis. On the other hand, the circadian rhythm has a direct relationship with osteoporosis. This has been found by the biochemical markers, indicating that fasting at certain hours of the day, especially during those hours of the day which are recommended as part of the Muslim tradition, is very effective in reducing the effects of osteoporosis.

Many conditions affect renal size. To evaluate abnormalities in renal size, knowledge of standardised values for normal renal dimensions is essential as it shows variability in the values of normal renal size depending on body size, age and ethnicity. Ultrasound, being an easily available, non-invasive, safe and less expensive modality, is widely used for evaluation of renal dimensions and repeated follow-ups. The objectives of this study were to determine renal size by ultrasound in adults without any known renal disease, and to determine the relationship of renal size with body mass index. Methods: Study was conducted in the Department of Diagnostic Radiology, Shifa International Hospital and PIMS Islamabad. Renal size was assessed by ultrasound in 4,035 adult subjects with normal serum creatinine and without any known renal disease, between November 2002 and December 2010. Renal length, width, thickness and volume were obtained and mean renal length and volume were correlated with body mass index and other factors like age, side, gender, weight and height of the subjects. Results: Mean renal length on right side was 101.6+-8.9 mm, renal width 42.7+-7.1 mm, and parenchymal thickness 14.4+-2.9 mm. On left side, mean renal length was 102.7+-9.2 mm, width 47.6+-7.0 mm, and parenchymal thickness 15.1+-3.1 mm. Mean renal volume on right was 99.8+-37.2 cm/sup 3/ and on left was 124.4+-41.3 cm/sup 3/. Left renal size was significantly larger than right in both genders. Relationship of mean renal length was significant when correlated with age, side, gender, height and weight, and body mass index. Renal volumes also showed a similar relationship with side, gender, height and weight, and body mass index; but with age such a relationship was seen only for left kidney. Conclusion: Pakistani population has mean renal size smaller than reference values available in international literature. Renal length and volume have a direct relationship with body mass index.

We have performed CT scans on 15 children and 2 young adults with severe renal inflammatory disease. Most children with urinary tract infections do not require such evaluation. We have, however, found CT helpful in defining the nature of renal abnormality and in defining the extent of disease in selected patients who either presented as diagnostic dilemmas or who did not respond initially to proper medical treatment. We therefore use CT scanning as our initial examination in such problem patients. (orig.)

Full Text Available Objective: To determine the presence of linear relationship between renal cortical thickness, bipolar length, and parenchymal thickness in chronic kidney disease patients presenting with different estimated glomerular filtration rates (GFRs and to assess the reproducibility of these measurements using ultrasonography. Materials and Methods: Ultrasonography was performed in 54 chronic renal failure patients. The scans were performed by two independent and blinded radiologists. The estimated GFR was calculated using the Cockcroft-Gault equation. Interobserver agreement was calculated and a linear correlation coefficient (r was determined in order to establish the relationship between the different renal measurements and estimated GFR. Results: The correlation between GFR and measurements of renal cortical thickness, bipolar length, and parenchymal thickness was, respectively, moderate (r = 0.478; p < 0.001, poor (r = 0.380; p = 0.004, and poor (r = 0.277; p = 0.116. The interobserver agreement was considered excellent (0.754 for measurements of cortical thickness and bipolar length (0.833, and satisfactory for parenchymal thickness (0.523. Conclusion: The interobserver reproducibility for renal measurements obtained was good. A moderate correlation was observed between estimated GFR and cortical thickness, but bipolar length and parenchymal thickness were poorly correlated.

Full Text Available The calcium phosphoric metabolism was analyzed depending on the severity of renal functioning disorders. Chronic renal disease is known to be associated with impaired mineral metabolism in terms of hypocalcaemia, hyperphosphatemia and enhanced level of Ca × P product that aggravates in chronic renal failure progression. The majority of patients with nephropathy have parathyroid hormone concentration to be different from target one recommended by NKF-K/DOQI (2003, at that secondary hyperparathyroidism prevails on pre-dialysis stage of chronic renal disease, the relative hypoparathyroidism is common among the patients received dialysis.

Full Text Available Background: The influence of metabolic syndrome (MetS on kidneys is related to many complications. We aimed to assess the association between MetS and chronic renal disease defined by a poor estimated glomerular filtration rate (eGFR and/or the presence of microalbuminuria/macroalbuminuria. Methods: 149 patients (77 males/72 females were enrolled in the study. Chronic renal disease was defined according to KDIGO 2012 criteria based on eGFR category and classified albuminuria. MetS was studied as a dichotomous variable (0 to 5 components including hypertension, waist circumference, low HDL-cholesterol, high triglycerides, and high glucose. Results: The association between clustering MetS and both classified eGFR and classified albuminuria (x2 = 50.3, p = 0.001 and x2 = 26.9, p = 0.003 respectively was found to be significant. The MetS presence showed an odds 5.3-fold (1.6–17.8 higher for low eGFR and 3.2-fold (1.2–8.8 higher for albuminuria in combination with the presence of diabetes mellitus, which also increased the risk for albuminuria by 3.5-fold (1.1–11.3. Albuminuria was significantly associated with high triglycerides, hypertension, high glucose (x2 = 11.8, p = 0.003, x2 = 11.4, p = 0.003 and x2 = 9.1, p = 0.01 respectively, and it was mildly associated with a low HDL-C (x2 = 5.7, p = 0.06. A significant association between classified eGFR and both high triglycerides and hypertension (x2 = 9.7, p = 0.04 and x2 = 16.1, p = 0.003 respectively was found. Conclusion: The clustering of MetS was significantly associated with chronic renal disease defined by both classified eGFR and albuminuria. The definition of impaired renal function by classified albuminuria was associated with more MetS components rather than the evaluation of eGFR category. MetS may contribute to the manifestation of albuminuria in patients with diabetes mellitus.

An Uncommon Reason of Osteoporosis: Spondyloepiphyseal Dysplasia Congenita

Full Text Available Skeletal dysplasia is a complex and rare disease group that presents with clinical and radiological findings that differ from classical metabolic bone diseases in which bone and cartilage tissue are affected together. Spondyloepiphyseal dysplasia conjenita with involvement of the spine and long bone epiphyses is seen with short stature and short body from birth. Although bone deformities such as shortness of neck and vertebrae, kyphosis, scoliosis, pectus carinatum, genu varum or valgum are frequent, association with osteopenia/osteoporosis has been rarely reported. Although spondyloepiphyseal dysplasia tarda and osteopenia are coexisting in the literature, there is no evidence of the association of spondyloepiphyseal dysplasia tarda and conjunctiva with osteoporosis. In our case report, we presented a patient who was applied to our center with short stature, diagnosed with osteoporosis and spondyloepiphyseal dysplasia congenita by detecting femur head aplasia in radiological imaging.

Lithium is an essential treatment in bipolar disorder and treatment-resistant depression; however, its use has been limited by concerns regarding its renal adverse effects. An improved understanding of potential molecular mechanisms can help develop prevention and treatment strategies for lithium-associated renal disease. We conducted a systematic literature search using MEDLINE, Embase, and PsychINFO including English-language original research articles published prior to November 2015 that specifically investigated lithium's effects on nephrogenic diabetes insipidus (NDI) and chronic kidney disease (CKD), using molecular markers. From a total of 3510 records, 71 pre-clinical studies and two relevant clinical studies were identified. Molecular alterations were reported in calcium signaling, inositol monophosphate, extracellular-regulated, prostaglandin, sodium/solute transport, G-protein-coupled receptors, nitric oxide, vasopressin/aquaporin, and inflammation-related pathways in lithium-associated renal disease. The majority of studies found that these mechanisms were implicated in NDI, while few studies had examined CKD. Future studies will have to focus on (1) validating the present findings in human subjects and (2) examining CKD, which is the most clinically relevant lithium-associated renal effect. This will improve our understanding of lithium's biological effects, as well as inform a personalized medicine approach, which could lead to safer lithium prescribing and less renal adverse events.

2011-04-01

Full Text Available Aim: Osteoporosis is a skeletal disease characterized with decreased bone mass and microarchtitectural deterioration of bone tissue which increases bone fragility and fracture risk. Osteoporosis and osteoporotic fractures constitute an important health problem in general population. This study aimed to determine the incidence of osteoporosis, chronic diseases accompanying osteoporosis and incidence of falls in male and female patients admitted to our out patient clinics retrospectively. Material and Methods: Patient records of the 11624 patients admitted to Ankara Atatürk Education and Research Hospital Physical Medicine and Rehabilitation Outpatient clinics between January 2010 and July 2010 were retrospectively reviewed and 644 patients diagnosed as osteoporosis according to femoral neck and/or lumbar dual energy x ray absoptiometry measurements were included in the study. Ages of the patients, sexes, chronic ilnesses, musculoskeletal sytem complaints and fall histories were also recorded. Results: The incidence of osteoporosis was found to be 7.61% in female patients and it was determined that incidence was 5-fold increased in women than in men. Besides, chronic ilnesses and fall history were accompanying in higher ratios in osteoporotic patients. Conclusion: Heart diseases, hypertension, diabetes, neurological diseases leading to impairment in balance and musculoskelatal system complaints were quite frequent in patients with osteoporosis and these diseases should be taken seriously since they increase the risk of falling. It is important to avoid using drugs which lead to balance impairment, to use walk aids like canes or walkers, to perform exercises including balance and coordination training and endurance exercises in order to prevent falls.

To explore the difference in carotid intima-media thickness (CIMT) between postmenopausal women with and without osteoporosis and the risk of elevated CIMT and plaque presentation. A cross-sectional study was conducted including 46 postmenopausal women with osteoporosis and 45 non-osteoporotic postmenopausal women. CIMT was measured using B-mode ultrasound. There was no statistically significant difference in mean CIMT between postmenopausal women with osteoporosis and those without osteoporosis (p > 0.05). Risk for elevated CIMT in the osteoporosis group was comparable to that of the non-osteoporosis group (adjusted odds ratio = 0.844; 95% confidence interval 0.11-6.45). The risk for the presence of plaque was three times higher in osteoporotic women than in normal individuals. However, after adjusting for age and underlying diseases that would predispose the women to cardiovascular disease, there was no significant difference in terms of presence of plaque between the two groups (adjusted odds ratio = 0.844; 95% confidence interval 0.11-6.45). There was no difference in mean CIMT between postmenopausal women with and without osteoporosis. Risk of elevated CIMT in postmenopausal women with osteoporosis was comparable to that of postmenopausal women without osteoporosis. There was no significant difference between the two groups in terms of the presence of plaque.

Osteoporosis is a chronic disease, carrying an elevated risk of fractures, morbidity, and death. Long-term treatment may be required, but the long-term risks with osteoporosis drugs remain incompletely understood. The competing risk of death may be a barrier to treating the oldest, yet this may...... not be rational if the risk of death is reduced by treatment. It is difficult to devise goal-directed long-term strategies for managing osteoporosis without firm information about residual life expectancy in treated patients. We conducted an observational study in Danish national registries tracking prescriptions...... for osteoporosis drugs, comorbid conditions, and deaths. We included 58,637 patients and 225,084 age- and sex-matched control subjects. Information on deaths until the end of 2013 was retrieved, providing a follow-up period of 10 to 17 years.

Chronic pain is a prominent feature of autosomal dominant polycystic kidney disease that is difficult to treat and manage, often resulting in a decrease in quality of life. Understanding the underlying anatomy of renal innervation and the various etiologies of pain that occur in autosomal dominant polycystic kidney disease can help guide proper treatments to manage pain. Reviewing previously studied treatments for pain in autosomal dominant polycystic kidney disease can help characterize treatment in a stepwise fashion. We performed a literature search of the etiology and management of pain in autosomal dominant polycystic kidney disease and the anatomy of renal innervation using PubMed® and Embase® from January 1985 to April 2014 with limitations to human studies and English language. Pain occurs in the majority of patients with autosomal dominant polycystic kidney disease due to renal, hepatic and mechanical origins. Patients may experience different types of pain which can make it difficult to clinically confirm its etiology. An anatomical and histological evaluation of the complex renal innervation helps in understanding the mechanisms that can lead to renal pain. Understanding the complex nature of renal innervation is essential for surgeons to perform renal denervation. The management of pain in autosomal dominant polycystic kidney disease should be approached in a stepwise fashion. Acute causes of renal pain must first be ruled out due to the high incidence in autosomal dominant polycystic kidney disease. For chronic pain, nonopioid analgesics and conservative interventions can be used first, before opioid analgesics are considered. If pain continues there are surgical interventions such as renal cyst decortication, renal denervation and nephrectomy that can target pain produced by renal or hepatic cysts. Chronic pain in patients with autosomal dominant polycystic kidney disease is often refractory to conservative, medical and other noninvasive treatments

Vietnamese women are at particular risk of osteoporosis and its complications. This study examined osteoporosis knowledge and awareness among Vietnamese women who have accessed health care. A sample of 217 women, 13 to 76 years of age, who were attending 1 of 2 health care facilities in Da Nang, Vietnam, between November and December 2009 completed a questionnaire assessing their awareness of osteoporosis and measuring their knowledge using a 30-item instrument reflecting 9 knowledge domains (eg, risk factors, diagnosis, prognosis). A majority (81.6%) of the women had heard of osteoporosis. Awareness was associated with education, working in health care, and having a family member with osteoporosis. On average, Vietnamese women answered 49% of the knowledge questions correctly; scores ranged from 0 to 26 questions correct out of 30 (mean = 14.71 ± 5.2, median = 15). Mean knowledge scores were higher among those reporting a family member with osteoporosis, nurses (vs other vocations), and women with a high school education or greater (relative to those who had not completed high school). More than 90% of the women expressed interest in a prevention and treatment program. Vietnamese women may have heard of osteoporosis, yet they would benefit from education targeting prevention and treatment of the disease. © 2011 APJPH.

Glomerulography is a useful method for the angiographic diagnosis of various renal parenchymal diseases. A new system for digitalization of the glomerulogram has been developed using a high resolution television camera and a CT computer. We describe the fundamental procedures involved in the clinical application of digital glomerulography by applying this method to a renal microangiogram of a cow. This new method aids a clearer understanding of the detailed microvasculatures by providing better magnification and storage and allowing for further processing of the original analogue images. With a computer printout of any part of the glomerulogram also possible, an estimation of the glomerular counts and their distribution can now be given for any unit of cross-sectional area of the renal cortex.

Paleopathologists have identified osteoporosis in ancient skeletons and modern physicians and scientists have identified risk factors for osteoporosis today, but they are not clearly linked, making it more difficult to clarify the causes of osteoporosis in the past. The evidence for osteoporosis in the remote past, its causes, and the management of this disease is reviewed in the light of evolving and improving diagnostic modalities, more precise definitions, and the recent rapid expansion of therapeutic options. While the specific effects of parity and lactation on the development of osteoporosis are still not entirely clear, duration of reproductive span and age at first pregnancy appear to be significant predisposing factors.

Due to its incidence and clinical consequences osteoporosis followed by vertebral, hip, and forearm fractures represents an outstanding problem of nowadays' health care. Because of its high mortality rate hip fractures are of special interest. The number of fractures caused by postmenopausal osteoporosis increases with age. Costs of examinations and treatment of women with postmenopausal osteoporosis and fractures are also increasing and represent a significant amount all over the world. Organization of Osteoporosis Centres in Hungary was founded in 1995 and has been since functioning, however, only the one-sixth of osteoporotic patients are treated. Several risk factors are known in the pathogenesis of osteoporosis, first of all the lack of sufficient calcium and vitamin D intake, age, genetic factors, and circumstances known to predispose falling. Estrogen deficiency is the most likely cause of postmenopausal osteoporosis. Osteodensitometry by DEXA is the most important method to evaluate osteoporosis, since decrease in bone mineral density strongly correlates with fracture incidence. Physical, radiologic, and laboratory examination are also required at the first visit and during follow-up. The quantity of bone can hardly be influenced after the 35th year of age, thus prevention of osteoporosis has special significance: appropriate calcium and vitamin D supplementation, weight-bearing sports and physical activity can prevent fractures. According to the results from studies fulfilling the criteria of evidence-based medicine, first choice treatment of osteoporosis involves hormone replacement therapy, bisphosphonates, the tissue specific tibolone, raloxifen and calcitonin. Calcium and vitamin D supplementation are always necessary to be added to any antiporotic treatment. Other combinations of different antiporotic drugs are useless and make the treatment more expensive. Other treatments like massage, physiotherapy, hip-protecting pants, etc. as well as

Chronic viral liver disease is often associated with other conditions. Diabetes mellitus (DM) is frequently reported in this context and may play a role in the progression of the liver disease to hepatocellular carcinoma (HCC). Renal disease is also an important extrahepatic manifestation of hepatitis viral infection and its presence is associated with poor prognosis and management issues. Our study had multiple purposes: to determine the frequency of the association between chronic viral liver disease and diabetes mellitus, evaluate the potential of diabetes mellitus as a risk factor for HCC and assess an eventual renal involvement. We included in our study a number of 246 patients with chronic liver disease, from whom 136 were diagnosed with chronic viral hepatitis and 110 with viral liver cirrhosis. These patients were assessed by using a clinical examination and a series of tests, including serum transaminase levels, serum bilirubin, serum albumin, markers of cholestasis, fasting plasma glucose levels, serum creatinine, urea, albuminuria, Addis-Hamburger test, electrophoresis of urinary proteins, abdominal ultrasound and, in some cases, CT examination. We obtained the following results: diabetes mellitus is often associated with chronic liver disease of viral etiology, having been identified in 18.29% of the patients in our study. Age above 60 in patients with chronic hepatitis (p=0.013diabetes mellitus. Renal disease was present in 13.4% of the patients with chronic liver disease and it was especially associated with liver cirrhosis and hepatitis C virus. The most common form of renal injury was glomerulonephritis. Acute kidney injury was diagnosed only in cirrhotic patients as hepatorenal syndrome, occurring in 7.27% of the subjects, while chronic kidney disease was identified only in two cases of chronic viral hepatitis. Four patients in our study were diagnosed with HCC and none of them presented diabetes mellitus. Our study revealed that there is a

Full Text Available Furosemide test is a simple and useful test of renal physiology used to evaluate the capability of the collecting tubules to secrete potassium under the effect of serum aldosterone. Its behaviour pattern has already been established in children and young adults but not described in chronic renal disease patients yet, which we explored in this study.Material & Method: Twenty-six young volunteers (between 20 and 40 years old, chronically on a low potassium diet (40 mmol of K day were studied: twenty of them were healthy young ( they were neither suffering form diseases nor on any medication, and the rest were young patients suffering from stage II / III chronic renal disease (damaged kidney with GFR between 83.1 ml-min to 39.2 ml-min secondary to glomerular diseases documented by kidney biopsy. None of the studied chronic renal disease patients were suffering from diabetes mellitus, urinary obstruction, nor treated with dyskalemia generating drugs, such as: diuretics, angiotensin converting enzyme inhibitors, angiotensin receptor antagonists, etc. Before, while the test was being carried out and after 180 minutes of a single dose of intravenous furosemide (1 mg/kg, urine and blood samples were obtained, for creatinine and potassium levels. From these data we calculated fractional excretion (FE of potassium.

Background: Renal artery stenosis (RAS) is a common finding in patients undergoing coronary angiography. We designed this study to look for the frequency and any predictors of renal artery stenosis in patients with coronary artery disease (CAD). Methods: A total of 201 consecutive patients with CAD confirmed by coronary angiography underwent an abdominal aortogram in the same sitting to screen for RAS. Patient demographics and co-morbidities were analysed for any association with RAS. Results: Forty-one of the patients were female (20.4%); ninety patients were hypertensive (44.8%); 49 patients (24.4%) were smokers; 19 patients (9.5%) had renal insufficiency; 88 patients (43.8%) had high cholesterol levels; 44 patients (21.9%) were diabetic. Thirty-two patients (15.9%) had single coronary artery disease, 59 patients (29.4%) had two vessel disease, and 110 patients (54.7%) had three vessel disease. Significant renal artery stenosis (less or equal to 50% stenosis) was present in 26 patients (12.9%). Among the variables studied, only female gender was found to be associated with a higher frequency of renal artery stenosis (24.39% vs 10.0%, p=0.01). Conclusions: The frequency of renal artery stenosis in patients with coronary artery disease is 12.9%. Female gender is associated with a higher frequency of renal artery stenosis in patients with CAD. (author)

Chronic kidney disease (CKD) is associated with a range of metabolic bone diseases. Fracture rates are higher in CKD patients than age-matched controls throughout all the five stages of CKD. Dialysis patients have 4 times as many hip fractures as expected for their age. CKD forms an independent risk factor for osteoporosis, even in the absence of traditional risk factors. This study was carried out at the nephrology unit in a tertiary care center of Kashmir to know the prevalence of osteoporosis in CKD patients having glomerular filtration rate (GFR) stages 3-5). Among the 151 cases studied, the average estimated GFR was 16.78 ± 10.714 mL/min. There were 98 males (64.9%) and 53 females (35.1%). Their mean age was 51.01 ± 14.138 years. Osteoporosis based on femoral neck T-Score was seen in 31 patients (31.6%) while 43 patients (28.5%) had osteoporosis at L1, L2 lumbar vertebrae. The prevalence of osteoporosis based on femoral neck T-Score as well as osteopenia was highest in stage-5 CKD. In our study, the body mass index (BMI) had a positive correlation with osteoporosis; low BMI patients were at higher risk for osteoporosis (P = 0.014). In the Kashmir valley, the prevalence of osteoporosis was 31.8% in CKD patients against 22% in controls. Thus, CKD forms an important risk factor for osteoporosis even in the absence of traditional risk factors. We recommend early screening, detection, and management of osteoporosis to reduce the burden of morbidity and mortality in this subset of patients.

The scorecard summarises key indicators of the burden of osteoporosis and its management in each of the member states of the European Union. The resulting scorecard elements were then assembled on a single sheet to provide a unique overview of osteoporosis in Europe. The scorecard for osteoporosis in Europe (SCOPE) is an independent project that seeks to raise awareness of osteoporosis care in Europe. The aim of this project was to develop a scorecard and background documents to draw attention to gaps and inequalities in the provision of primary and secondary prevention of fractures due to osteoporosis. The SCOPE panel reviewed the information available on osteoporosis and the resulting fractures for each of the 27 countries of the European Union (EU27). The information researched covered four domains: background information (e.g. the burden of osteoporosis and fractures), policy framework, service provision and service uptake e.g. the proportion of men and women at high risk that do not receive treatment (the treatment gap). There was a marked difference in fracture risk among the EU27. Of concern was the marked heterogeneity in the policy framework, service provision and service uptake for osteoporotic fracture that bore little relation to the fracture burden. For example, despite the wide availability of treatments to prevent fractures, in the majority of the EU27, only a minority of patients at high risk receive treatment for osteoporosis even after their first fracture. The elements of each domain in each country were scored and coded using a traffic light system (red, orange, green) and used to synthesise a scorecard. The resulting scorecard elements were then assembled on a single sheet to provide a unique overview of osteoporosis in Europe. The scorecard will enable healthcare professionals and policy makers to assess their country's general approach to the disease and provide indicators to inform future provision of healthcare.

Addison's disease is a rare disorder in patients with end-stage renal disease (ESRD). In patients, the diagnosis of Addison's disease is difficult in clinical practice because most of the clinical findings of this disease are similar to those of the renal failure. We present a 51-year-old male patient, who underwent hemodialysis therapy for 8 years, diagnosed with Addison's disease after having myalgia, skin hyperpigmentation, weight loss, sweating, and nausea for the past few weeks. The physical examination was completely normal except for muscle weakness, hyperpigmentation on labial mucosa and skin in a patient. The laboratory tests revealed anemia and hypoglycemia. Serum cortisol, adrenocorticotropic hormone (ACTH) levels, and ACTH stimulation test results were consistent with Addison's disease. Adrenal computerized tomography revealed bilateral atrophic glands. Additionally, it was found that elevated serum thyroid stimulating hormone levels and antithyroid peroxidase antibody titer were positive. Our purpose is to emphasize that physicians should be alert to the potential for additional different conditions particularly in terms of adrenal failure in patients with ESRD.

To determine renal function, 99m Tc-DMSA renal uptake was measured from renal tomographic images obtained by single photon emission computed tomography (SPECT). A total of 77 tests was conducted on 73 patients with various diseases in the kidneys and urinary tract to determine renal uptake. The correlation coefficient(r) between total renal volume and total renal uptake was 0.3509 and that between renal volume and uptake of 143 kidneys was 0.5433. In 62 patients whose creatinine clearance could be measured, the correlation coefficient between creatinine clearance and total renal volume was 0.2352, and that between creatinine clearance and total renal uptake was 0.8854, that is, creatinine clearance correlated well with renal uptake. Renal volume and uptake determined in 10 normal male and 10 normal female adults were 220 ml and 26.8 % for the right kidney and 239 ml and 27.6 % for the left kidney for the males and 206 ml and 26.4 % (right) and 237 ml and 27.9 % (left) for the females. This method, which requires no blood or urine collection, is very useful as an individual kidney function test to evaluate individual kidney function and to understand kidney function before and after operation in patients with renal and urinary diseases.

The purpose of the report is presentation of the experiences collected in the diagnosis of renal changes obtained by means of computerized tomography after application of this method in 800 examinations of the abdominal cavity. In 88 cases the examination was performed because of diagnosed or supposed renal disease. The examination was done using an EMI Medical CT 5005/2 whole-body scanner. In the group of 88 cases in 22 unilateral or bilateral hydronephros was diagnosed, in 16 cases single cysts were demonstrated in the kidneys, in 5 polycystic renal disease, in 9 malignant neoplasms and in 11 nephrosclerosis were found. Besides that, atrophic kidneys were recognized and patients were examined after nepherctomy carried out for neoplasm. The final diagnosis was based on surgical, autopsy, angiographic and clinical findings. Computerized tomography of the kidneys is important mainly as a method supplementing traditional methods of examination of the kidneys. The main indication to the use of this method as the first radiological examination of the kidneys is in search for the cause of morphological renal failure, so called ''dumb kidney'' in urography, and in search for retroperitoneal metastases and recurrences after operations of renal neoplasms. In all other circumstances it should be accepted as a rule to begin renal examination with plain-film taking and intravenous urography, which methods together with other classic radiological methods make possible recognition of the causes of renal diseases in most cases.

It has been suggested that the progressive fall in renal function in some patients with CRF is due to hyperfusion of the remnant nephrons in response to the relatively high protein diet of modern life. The authors attempted to assess this and to see what was the shortest time in which any effect could be demonstrated. In the first phase, 39 patients with CRF had their renal function followed for 6 months on their normal diet and 6 months on a low-protein diet (LPD). The patients on LPD all showed an improvement in the rate of fall of renal function. This was marked in patients with mainly tubular disease, and poor in those with glomerular and vascular disease. In the second phase, 11 of these patients (and 1 other) were started on a high protein diet (HPD) for two weeks, and then switched back to a LPD for 2 weeks. There was no change in GFR during this period, but there were marked changes in ERPF, which correlated well with the changes in renal function in the first phase (r = 0.76, rho < 0.01); 4/4 patients with tubular disease showed a rise in ERPF on HPD and a fall on LPD, while only 4/8 with glomerular or vascular disease responded. In the third phase, they assessed the effect of a single high-protein meal in normal volunteers. This showed that there are major changes in hemodynamics following a meal, such that it is not possible to make any statement about renal function using the single-shot methods. The authors conclude that a 2-week period of HPD followed by LPD allows prediction of the possible beneficial response to diet in CRF; that this is best monitored by ERPF; and that a single meal may invalidate renal function measurement

Full Text Available Transient osteoporosis is a process in which peri-articuler osteoporosis occurs, with cartilage remaining intact. A painful disease, it is more common in males than females, may be migratory and is self-limited, with complete resolution of symptoms and all imaging findings. Characterized by pain and functional limitation mainly affecting weight-bearing joints of the lower limbs. Routine laboratory investigations are unremarkable. Middle aged men and women during the last months of pregnancy or in the immediate post-partum period are principally affected. Diagnosis is made upon clinical presentation and x-ray evidence of diffuse osteopenia in the affected bone area followed by spontaneous healing after several months. Magnetic resonance imaging and techneticum-99 bone scan may be helpful in diagnosis especially in early phase of the disease. In this case report 41 year old male patient who had transient osteoporosis of the hip was evaluated in the light of relevant literature. (From the World of Osteoporosis 2007;13:19-22

Osteoporosis Prevention—A Worthy and Achievable Strategy

Full Text Available This special issue of Nutrients records seven of the presentations made to the very successful meeting titled “Osteoporosis Prevention: A Workshop on Calcium, Vitamin D and other Nutritional Aspects” held in Adelaide, Australia on 5 and 6 March 2010 [1-7]. Seventy six delegates attended from across Australia and New Zealand to review the current evidence that dietary calcium intake, vitamin D status, other nutrients and exercise play a significant role in bone mineral homeostasis and act to prevent the development of osteoporosis. The Workshop promoted the concept that osteoporosis is a predictable and preventable disease and that significant benefit would be achieved to reduce the incidence of osteoporosis and the risk of fractures from nutrition and life style activities. Such an achievement will not only save considerable pain, suffering and morbidity but will also have a major financial benefit for the healthcare system for which the cost of treatment for osteoporotic fractures already amounts to billions of dollars.

Transient regional osteoporosis (TRO) is a disease that predisposes to fragility fracture in weight bearing joints of mid-life women and men. Pregnant women may also suffer the process, usually at the hip. The prevalence of TRO is lower than the systemic form, associated with postmenopause and advanced age, but may be falsely diminished by under-diagnosis. The disease may be uni- or bilateral, and may migrate to distinct joints. One main feature of TRO is spontaneous recovery. Pain and progressive limitation in the functionality of the affected joint(s) are key symptoms. In the case of the form associated with pregnancy, difficulties in diagnosis derive from the relatively young age at presentation and from the clinical overlapping with the frequent aches during gestation. Densitometric osteoporosis in the affected region is not always present, but bone marrow edema, with or without joint effusion, is detected by magnetic resonance. There are not treatment guidelines, but the association of antiresorptives to symptomatic treatment seems to be beneficial. Surgery or other orthopedic interventions can be required for specific indications, like hip fracture, intra-medullary decompression, or other. Copyright © 2014 Elsevier Ireland Ltd.

To update the 1993 burden of illness of osteoporosis in Canada, administrative and community data were used to calculate the 2010 costs of osteoporosis at $2.3 billion in Canada or 1.3% of Canada's healthcare expenditures. Prevention of fractures in high-risk individuals is key to decrease the financial burden of osteoporosis. Since the 1996 publication of the burden of osteoporosis in 1993 in Canada, the population has aged and the management of osteoporosis has changed. The study purpose was to estimate the current burden of illness due to osteoporosis in Canadians aged 50 and over. Analyses were conducted using five national administrative databases from the Canadian Institute for Health Information for the fiscal-year ending March 31 2008 (FY 2007/2008). Gaps in national data were supplemented by provincial and community data extrapolated to national levels. Osteoporosis-related fractures were identified using a combination of most responsible diagnosis at discharge and intervention codes. Fractures associated with severe trauma codes were excluded. Costs, expressed in 2010 dollars, were calculated for osteoporosis-related hospitalizations, emergency care, same day surgeries, rehabilitation, continuing care, homecare, long-term care, prescription drugs, physician visits, and productivity losses. Sensitivity analyses were conducted to measure the impact on the results of key assumptions. Osteoporosis-related fractures were responsible for 57,413 acute care admissions and 832,594 hospitalized days in FY 2007/2008. Acute care costs were estimated at $1.2 billion. When outpatient care, prescription drugs, and indirect costs were added, the overall yearly cost of osteoporosis was over $2.3 billion for the base case analysis and as much as $3.9 billion if a proportion of Canadians were assumed to be living in long-term care facilities due to osteoporosis. Osteoporosis is a chronic disease that affects a large segment of the adult population and results in a

Full Text Available Introduction : Osteoporosis as a chronic disease, affecting especially women in postmenopausal age, is an important, social and economic health problem especially of women of today’s world. The aim of the study was to assess the level of knowledge of women in the peri- and postmenopausal period about the prevention of osteoporosis and show the influence of chosen risk factors on the level of this knowledge. Material and methods : A group of 300 women aged 45-65, being patients of healthcare centres in Chełm, Lublin and Zamość (Lublin voivodeship, south-eastern Poland were included in the study. The purposive sampling was used. Osteoporosis Knowledge Test (OKT 2011 was the research tool. Gathered material was subjected to descriptive and statistical analysis. Tukey’s test, t-student test and variance analysis (ANOVA were all applied. An accepted p materiality level was < 0.05 and p < 0.01. Results : Respondents presented the average level of knowledge about the role of physical activity in the prevention of osteoporosis (M = 13.93 and a low level of knowledge about well-balanced diet rich in calcium (M = 9.77. The knowledge about risk factors, screening and treatment remained on the average level (M = 8.00. An influence of socio-demographic factors on the level of knowledge was shown. Also some behaviours, associated with the lifestyle indeed influenced the level of this knowledge. Conclusions : Professional educational programs on osteoporosis should be implemented in the population of Polish peri- and postmenopausal women.

Magdalena Weber-Rajek

2015-01-01

Full Text Available The report of the World Health Organization (WHO of 2008 defines osteoporosis as a disease characterized by low bone mass and an increased risk of fracture. Postmenopausal osteoporosis is connected to the decrease in estrogens concentration as a result of malfunction of endocrine ovarian function. Low estrogens concentration causes increase in bone demineralization and results in osteoporosis. Physical activity, as a component of therapy of patients with osteoporosis, has been used for a long time now. One of the forms of safe physical activity is the vibration training. Training is to maintain a static position or execution of specific exercises involving the appropriate muscles on a vibrating platform, the mechanical vibrations are transmitted to the body of the patient. According to the piezoelectric theory, pressure induces bone formation in the electrical potential difference, which acts as a stimulant of the process of bone formation. Whole body vibration increases the level of growth hormone and testosterone in serum, preventing sarcopenia and osteoporosis. The aim of this study was to review the literature on vibration exercise in patients with postmenopausal osteoporosis based on the PubMed and Medline database. While searching the database, the following key words were used ‘postmenopausal osteoporosis’ and ‘whole-body vibration exercise’.

Full Text Available Aim: Osteoporosis is a skeletal disorder in which the bones become weak, brittle, and more likely to break. This disease is excessively prevalent among women, but it may also affect the male individuals. There is a lack of studies, which have assessed men’s knowledge and beliefs in Jordan about osteoporosis. Thus, this study aims to explore the level of knowledge and health beliefs regarding osteoporosis among Jordanian men at Karak city. Method: A descriptive and cross-sectional study was conducted after recruiting 88 men, who attended a primary healthcare centre at Karak city. Men’s knowledge of osteoporosis was assessed using two instruments; “The Facts on Osteoporosis Quiz” and the “Male Osteoporosis Knowledge Quiz”. Osteoporosis health beliefs were assessed using the “Osteoporosis Health Belief Scale”. Results: Most of the selected participants reported that they have heard about osteoporosis before. The main source of osteoporosis information was mass media (43.18%, which was followed by family members or friends (25%. The studied sample scored a mean of 9.02 out of 26 with a range of 3 to 16, reflecting 34.70% of the maximum possible score. The selected participants had a low perceived susceptibility, moderate perceived seriousness, high perceived benefits of exercise and calcium intake, low perceived barriers to calcium intake compared to moderate perceived barrier to exercise, and moderate perceived health motivation. Conclusion: Educational interventions are required to increase men’s awareness about the seriousness of osteoporosis and its impact in later life. Healthcare providers should focus more on increased awareness level about osteoporosis.

To assess the relationship between cardiovascular risk factors and osteoporosis. 2202 women aged 50 - 73 years were included in this cross-sectional study from the communities in Guangzhou, from July 2008 to January 2010. Cardiovascular risk factors including age, years since menopause, physical activity, anthropometrics, body composition, blood pressure, fasting serum lipids, glucose and uric acid, intima-media thickness (IMT) of carotid artery were assessed. Ultrasonic bone density (speed of sound) at the radius and tibia were determined. Osteoporosis was defined as T-score ≤ -2.5. Common factors for the cardiovascular risk factors were extracted using the factor analysis method. Eight common factors representing obesity, lean mass, blood triglycerides and uric acid, cholesterol, age, blood pressure, IMT and physical activity were extracted. Data from the Multivariate logistic regression showed a dose-dependent association of greater scores of age and IMT factors and lower score of lean mass factor with the increased risk of osteoporosis at the radius and tibia. As compared with the bottom quartile, the OR (95%CI) of radius and tibia osteoporosis were 0.62 (0.44 - 0.88) and 0.62 (0.48 - 0.80) for lean mass factor, 4.02 (2.72 - 5.94) and 3.68 (2.81 - 4.82) for age factor, 1.41 (1.00 - 2.00) and 1.54 (1.19 - 2.00) for IMT factors, respectively. Moreover, greater blood pressure score was associated with higher risk of radius osteoporosis while the higher obese score, was correlated with the increased risk of tibia osteoporosis. The cardiovascular-related risk factors of greater IMT, obesity, blood pressure and lower lean mass scores were associated with increased osteoporosis risks while called for more concern among the Chinese women.

Background: Renal involvement in patients with lymphoproliferative disease is an uncommon radiological finding. Purpose: To determine its prevalence and radiological appearances in a patient population. Material and Methods: All forms of lymphoproliferative disease (ICD: C81-C96) were considered. From January 2005 to January 2010, 668 consecutive patients with lymphoproliferative disease were identified with the help of the radiological database and patient records. Inclusion criteria were complete staging including appropriate CT scan and/or MRI. All stored images (initial staging and follow-up examinations) were reviewed. Results: Review of all stored images revealed renal infiltration in patients with non-Hodgkin lymphoma (11 of 364 = 3.0%; median age = 65 years, m:f = 6:5) but also multiple myeloma (2 of 162 = 1.2%; median age = 72 years; m:f = 1:1) and leukemia (5 of 101 4.9%; median age = 12 years; m:f = 2:3). There were no cases of renal infiltration in 41 patients with Hodgkin's disease. In total there were six patients with solitary lesions, five patients with diffuse renal enlargement, four patients with perirenal lesions, and two patients with direct invasion of the kidney. Conclusion: In leukemia the most common imaging pattern is diffuse enlargement. In the other subtypes of lymphoproliferative disease no specific correlation between typical CT patterns and subtype of lymphoproliferative disease can be found. The prevalence of renal involvement is in line with earlier studies. Contrary to earlier reports, multiple lesions were not found to be a common pattern

End-stage renal disease in Nigeria: An overview of the epidemiology and the pathogenetic mechanisms

Full Text Available There is paucity of information on the magnitude of the burden of renal disease in our environment. Obtaining accurate data is hampered by the poor socioeconomic status of most patients with lack of access to specialized care in tertiary institutions, where most of the data is generated. The incidence of chronic renal failure (CRF and end-stage renal disease (ESRD in any specified area is known to be influenced by the prevalence of specific disease entities resulting in CRF. Hypertension, glomerulonephritis (GN, sickle cell disease, quartan malaria nephropathy, urinary tract schistosomiasis and other parasite-related forms of chronic GN are known to contribute significantly to the incidence of CRF in Nigeria. As is the situation in other parts of the world, diabetic nephropathy appears to be of increasing importance in the causation of ESRD in Nigeria. Even though the underlying cause of renal disease can often not be treated, extensive studies in experimental animals and preliminary studies in humans suggest that progression in chronic renal disease may largely be due to secondary factors, attention to which may be important in the prevention and/or control of renal disease.

End Stage and Chronic Kidney Disease: Associations with Renal Cancer

International Nuclear Information System (INIS)

Russo, Paul

2012-01-01

There is a well known association between end stage renal disease and the development of kidney cancer in the native kidney of patients requiring renal replacement therapy. There is now emerging evidence that lesser degrees of renal insufficiency (chronic kidney disease, CKD) are also associated with an increased likelihood of cancer in general and kidney cancer in particular. Nephropathological changes are commonly observed in the non-tumor bearing portions of kidney resected at the time of partial and radical nephrectomy (RN). In addition, patients with renal cancer are more likely to have CKD at the time of diagnosis and treatment than the general population. The exact mechanism by which renal insufficiency transforms normal kidney cells into tumor cells is not known. Possible mechanisms include uremic immune inhibition or increased exposure to circulating toxins not adequately cleared by the kidneys. Surgeons managing kidney tumors must have an increased awareness of their patient’s renal functional status as they plan their resection. Kidney sparing approaches, including partial nephrectomy (PN) or active surveillance in older and morbidly ill patients, can prevent CKD or delay the further decline in renal function which is well documented with RN. Despite emerging evidence that PN provides equivalent local tumor control to RN while at the same time preventing CKD, this operation remains under utilized in the United States and abroad. Increased awareness of the bi directional relationship between kidney function and kidney cancer is essential in the contemporary management of kidney cancer.

An Update on Renal Artery Denervation and Its Clinical Impact on Hypertensive Disease

Full Text Available Hypertension is a globally prevalent condition, with a heavy clinical and economic burden. It is the predominant risk factor for premature cardiovascular and cerebrovascular disease, and is associated with a variety of clinical disorders including stroke, congestive cardiac failure, ischaemic heart disease, chronic renal failure, and peripheral arterial disease. A significant subset of hypertensive patients have resistant hypertensive disease. In this group of patients, catheter-based renal artery denervation has emerged as a potential therapy, with favourable clinical efficacy and safety in early trials. Additional benefits of this therapy are also being identified and include effects on left ventricular remodeling, cardiac performance, and symptom status in congestive cardiac failure. Utility of renal denervation for the management of resistant hypertension, however, has become controversial since the release of the Symplicity HTN-3 trial, the first large-scale blinded randomised study investigating the efficacy and safety of renal artery denervation. The aim of this paper is to evaluate the history, utility, and clinical efficacy of renal artery denervation technology, including an in-depth appraisal of the current literature and principal trials.

Antonio Junior Lepedda

2013-01-01

Full Text Available Fabry’s disease is a rare lysosomal storage disorder caused by the deficiency of α-galactosidase A that leads to the accumulation of neutral glycosphingolipids in many organs including kidney, heart, and brain. Since end-stage renal disease represents a major complication of this pathology, the aim of the present work was to evaluate if urinary proteoglycan/glycosaminoglycan excretion could represent a useful marker for monitoring kidney function in these patients at high risk. Quali-quantitative and structural analyses were conducted on plasma and urine from 24 Fabry’s patients and 43 control subjects. Patients were sorted for presence and degree of renal impairment (proteinuria/renal damage. Results showed that levels of urine bikunin, also known as urinary trypsin inhibitor (UTI, are significantly higher in patients with renal impairment than in controls. In this respect, no differences were evidenced in plasma chondroitin sulfate isomers level/structure indicating a likely direct kidney involvement. Noteworthy, urine bikunin levels are higher in patients since early symptoms of renal impairment occur (proteinuria. Overall, our findings suggest that urine bikunin level, as well as proteinuria, could represent a useful parameter for monitoring renal function in those patients that do not present any symptoms of renal insufficiency.

Radioiodine (RAI) is a cornerstone in the treatment of Differentiated Thyroid Cancer (DTC). In patients on haemodialysis due to End-Stage Renal Disease (ESRD), it must be used cautiously, considering the renal clearance of this radionuclide. Also, the safety of the procedure and subsequent long-term outcome is still not well defined. In 2001, we described a dosimetric method and short-term results in three patients, with a good safety profile. We hypothesize that our method is safe in a long-term scenario without compromising the prognosis of both renal and thyroid disease. Descriptive-retrospective study. A systematic search was carried out using our clinical database from 2000 to 2014. DTC and radioiodine treatment while on haemodialysis. peritoneal dialysis. Final sample n=9 patients (n=5 males), age 48 years (median age 51 years males, 67 years female group); n=8 papillary thyroid cancer, n=1 follicular thyroid cancer; n=5 lymph node invasion; n=1 metastatic disease. Median RAI dose administered on haemodialysis 100mCi. 7.5 years after radioiodine treatment on haemodialysis, n=7 deemed free of thyroid disease, n=1 persistent non-localised disease. No complications related to the procedure or other target organs were registered. After 3.25 years, n=4 patients underwent successful renal transplantation; n=4 patients did not meet transplantation criteria due to other conditions unrelated to the thyroid disease or its treatment. One patient died due to ischemic cardiomyopathy (free of thyroid disease). Radioiodine treatment during haemodialysis is a long-term, safe procedure without worsening prognosis of either renal or thyroid disease. Copyright © 2015 Elsevier España, S.L.U. and SEMNIM.

Renal transplantation is the optimal treatment for selected patients with end-stage renal disease (ESRD). However, the survival benefit of renal transplantation among patients with ESRD attributed to granulomatosis with polyangiitis (GPA) is unknown. We identified patients from the United States Renal Data System with ESRD due to GPA (ESRD-GPA) between 1995 and 2014. We restricted our analysis to waitlisted subjects to evaluate the impact of transplantation on mortality. We followed patients until death or the end of follow-up. We compared the relative risk (RR) of all-cause and cause-specific mortality in patients who received a transplant versus non-transplanted patients using a pooled logistic regression model with transplantation as a time-varying exposure. During the study period, 1525 patients were waitlisted and 946 received a renal transplant. Receiving a renal transplant was associated with a 70% reduction in the risk of all-cause mortality in multivariable-adjusted analyses (RR=0.30, 95% CI 0.25 to 0.37), largely attributed to a 90% reduction in the risk of death due to cardiovascular disease (CVD) (RR=0.10, 95% 0.06-0.16). Renal transplantation is associated with a significant decrease in all-cause mortality among patients with ESRD attributed to GPA, largely due to a decrease in the risk of death to CVD. Prompt referral for transplantation is critical to optimise outcomes for this patient population. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Clinical strategies to address patients' concerns in osteoporosis management with bisphosphonates.

Cole, Raymond E

2011-03-01

Approximately 44 million Americans either have, or are at risk of developing, osteoporosis, a disease associated with an increased risk of fracture and, consequently, morbidity and mortality. Osteoporosis affects 20% to 30% of postmenopausal women, and resulting fractures pose a major economic burden, with estimated annual direct costs ranging from $17 billion to $19 billion. Hip fractures account for the majority of costs (~60%) because they often require costly long-term follow-up care in addition to the direct costs of initial treatment. Screening, diagnosis, and disease management are of paramount importance when treating patients at risk for osteoporosis. The National Osteoporosis Foundation recommends that all postmenopausal women be evaluated for osteoporosis risk factors and that all women aged ≥ 65 years undergo bone mineral density testing. Once the primary care physician has identified a patient at risk for osteoporosis-related fracture, the physician must decide whether and how to treat the patient (ie, nonpharmacologic or pharmacologic options). Bisphosphonates are the first-line pharmacologic treatment for women aged ≥ 50 years with postmenopausal osteoporosis. Bisphosphonates-which have a favorable safety and tolerability profile in clinical trials-have shown efficacy in reducing fractures. However, achieved real world effectiveness is very much dependent on good treatment adherence by the patient. Media attention to rare adverse events has motivated some patients to deliberate nonadherence. Physicians should screen patients for contraindications and adverse event risk factors, educate them on the risks of fracture and benefits and risks of treatment, and monitor them during therapy. To assist primary care physicians in clinical decision making for women at risk for or with confirmed osteoporosis, this article presents a review of the guidelines for the diagnosis and treatment of postmenopausal osteoporosis, recent long-term efficacy data for

Full Text Available Osteoporosis is one of the major public health problems. Higher prevalence of most chronic diseases has been encountered in less educated subjects. Aim of this study was to assess educational status, knowledge and sources of information among subjects with osteoporosis. A multicentered trial involving 10 centers was carried out. Patients with bone mineral densities below –2.5 standard deviations either in femoral or lomber region were included in the study. Age, sex, height, weight, educational status, clothing style, drugs used for osteoporosis, age at menarche, age at menopause, type of menopause, oral contraception, presence of chronic disease, smoking status, physical activity level, calcium intake, knowledge about osteoporosis and sources of information was gathered using a questionnaire. 54 % of our patients had knowledge about osteoporosis. Doctors were the most commonly utilized source of information (56.8%. Patients were divided into 3 groups according to educational status: less than 5 years (392 patients, 68.9 %, 6 to 8 years (53 patients, 9.3 % and more than 9 years (124 patients, 21.8 %. Body mass index, presence of obesity, smoking status and physical activity levels were significantly different between the groups. Knowledge about osteoporosis was compared according to years of formal education. 43.7 % of patients with formal education less than five years, 62.3 % of patients with formal education 6-8 years and 83.7 % of patients with formal education more than 9 years had knowledge about osteoporosis. Knowledge about osteoporosis was significantly different between groups. Patients within different geographical regions were compared. Educational status, clothing style, smoking status, activity levels, calcium intake and knowledge about osteoporosis was found to be statistically significantly different between the groups. Education of both patients and doctors will lead to better understanding of concept of “bone health”.

Fortunately, a growing arsenal of therapies is becoming available to treat this disease and prevent fracture. A new class of anabolic agents has emerged within the last decade that brought with it a new concept in osteoporosis therapy: building new stronger bone rather than simply inhibiting bone turnover. Evidence is accumulating to understand how to best utilize these new agents, and which patients benefit most. This article will review the effectiveness, risks, timing and clinical uses of teriparatide in postmenopausal osteoporosis.Keywords: osteoporosis, menopause, teriparatide

Objectives The aim of this study was to assess the knowledge concerning osteoporosis among high school female students in Semnan, Iran and to evaluate the effect of educational program. Methods This pre and post-study was performed on 583 high-school female students, whom selected from 8 schools using multi-stage sampling. The study questionnaires were completed by interviewing students. All students participated in a single education session (about 2 hours and the level of knowledge about osteoporosis, its risk factors and complications were assessed before and after education. Results The mean ± SD score for general knowledge regarding osteoporosis was 0.35 ± 0.35, about complications of osteoporosis was -0.18 ± 0.53 and about risk factors for osteoporosis was also 0.25 ± 0.21. The mean total knowledge about osteoporosis was the highest in third high school grade girls (P = 0.009, while no difference was observed in score of knowledge towards osteoporosis across the different educational fields (P = 0.156. The mean total score of knowledge toward osteoporosis was significantly increased after educational intervention compared to prior to the educational program with the mean ± SD pre-educational score 0.23 ± 0.19 (median 0.26 and post-educational score 0.45 ± 0.22 (median 0.48 (P < 0.001. Conclusions In conclusion, our results indicated that awareness of Semnan high schools girls on osteoporosis, especially about its complications is poor. Lack of awareness could be due to the lack of training. Thus, more training needed with a focus on understanding the causes of disease and its complications in order to resolve the problem and reduce the incidence of osteoporosis. So by increasing awareness regarding

Full Text Available Objective: Osteoporosis is a disease which causes fractures depending on decreasing bone mineral density. Nutrition and life style which support the bone health must be known for prevention of the disease. This study was conducted to assess awareness about OP between men and women. Materials and Methods: The study was performed between the dates November 2012-May 2014 in Denizli Pamukkale University. A form including sociodemographic features, Osteoporosis Knowledge Test (OKT and Osteoporosis Health Belief Scale (OHBS were used in the collection of the data for evaluation the osteoporosis knowledge level and awarenes of the volunteers who accept to attend the study. Results: Hundred forty-seven volunteers of 96 women and 51 men attended to the study. Mean age was 36.1±14,6 years and 6.1% of the participants had a diagnosis osteoporosis and 13.6% of the participants had a family history of osteoporosis. When the participants were compared according to gender, there were statistically significant difference between two groups for education level, had own and a family history of osteoporosis (p<0,05. Men had higher education level than the women group. Women have higher own and familiy history of osteoporosis. When the scores of the questionnaires were compared between women and men, the mean score of the Osteoporosis Health Belief Scale- Susceptibility score was 16.8±5.0 and 13.7±4.0, respectively. The women’s score were higher than men (p<0.05. Significant difference wasn’t found in the other subscales. Conclusion: Despite the high educational level of the men, it was detected that the level of the osteoporosis susceptibility was lower than women. High Osteoporosis Health Belief Scale level of women shows that women think osteoporosis is serious illness. Since the basic treatment approach was the prevention for osteoporosis, the education programs must be organized for either women who have high risk, or also for men to improve the

Full Text Available Abstract Background Osteoporosis affects over 200 million people worldwide at a high cost to healthcare systems. Although guidelines are available, patients are not receiving appropriate diagnostic testing or treatment. Findings from a systematic review of osteoporosis interventions and a series of focus groups were used to develop a functional multifaceted tool that can support clinical decision-making in osteoporosis disease management at the point of care. The objective of our study was to assess how well the prototype met functional goals and usability needs. Methods We conducted a usability study for each component of the tool--the Best Practice Recommendation Prompt (BestPROMPT, the Risk Assessment Questionnaire (RAQ, and the Customised Osteoporosis Education (COPE sheet--using the framework described by Kushniruk and Patel. All studies consisted of one-on-one sessions with a moderator using a standardised worksheet. Sessions were audio- and video-taped and transcribed verbatim. Data analysis consisted of a combination of qualitative and quantitative analyses. Results In study 1, physicians liked that the BestPROMPT can provide customised recommendations based on risk factors identified from the RAQ. Barriers included lack of time to use the tool, the need to alter clinic workflow to enable point-of-care use, and that the tool may disrupt the real reason for the visit. In study 2, patients completed the RAQ in a mean of 6 minutes, 35 seconds. Of the 42 critical incidents, 60% were navigational and most occurred when the first nine participants were using the stylus pen; no critical incidents were observed with the last six participants that used the touch screen. Patients thought that the RAQ questions were easy to read and understand, but they found it difficult to initiate the questionnaire. Suggestions for improvement included improving aspects of the interface and navigation. The results of study 3 showed that most patients were able

Dynamic computed tomography was conducted by the original methods; the findings were analyzed by taking into account time-density curves which made it possible to gain an insight into the status of blood flow and filtration in each individual kidney. Computed tomography and dynamic computed tomography revealed that hypertensive disease was characterized by normal volume and thickness of the renal cortical layer and symmetric time-density curves, whereas a hypertensive type of chronic glomerulonephritis featured lower renal cartical layer thickness, reduced renal volume, symmetrically decrease amplitudes of the first and second peaks of the time-density curve, chronic pyelonephritis showed asymmetric time-density diagrams due to the lower density areas in the afflicted kidney

Full Text Available Osteoporosis is the most common bone disease and is an important problem of public health. In fact, it represents the main cause of age-related fractures and disabilities with a consequent increasing sanitary, social and economic impact. Unfortunately, often osteoporosis is not as thoroughly investigated as it would be desirable and it is underestimated in diagnosis and therapy. The aim of this monograph is to sensitize medical internists to a careful evaluation and an efficacious treatment of osteoporosis in order to reduce the risks of this disease, in particular the fractures, with a view to improving the quality of patients’ life.

The Putative Role of the Antiageing Protein Klotho in Cardiovascular and Renal Disease

Directory of Open Access Journals (Sweden)

Giuseppe Maltese

2012-01-01

Full Text Available Ageing is a multifactorial process often characterized by a progressive decline in physiological function(s. Ageing can and is often associated with an increased incidence of cardiovascular and renal disease. Klotho is a novel antiageing gene that encodes a protein with multiple pleiotropic functions including an emerging role in cardiorenal disease. Mice deficient for this gene display a phenotype of premature human ageing characterized by diffuse vascular calcification, altered calcium/phosphate metabolism, and shortened lifespan. Klotho is mainly expressed in the renal tubules but it also exists as circulating soluble form detectable in the blood, with systemic effects. Reduction in soluble Klotho has been associated with renal disease, hyperphosphataemia, increased oxidative stress, endothelial dysfunction, and diffuse vascular calcification. Conversely, overexpression of Klotho promotes cardiovascular-renal protection. The majority of the research on Klotho has been conducted in vitro and in animal studies but there is emerging data from human studies which suggest that Klotho may be a modifiable factor involved in the pathogenesis of cardiovascular and renal disease in at-risk populations. Further data is required to confirm if this novel protein can emerge as therapeutic tool that may be used to prevent or slow progression of cardiorenal disease.

Feline immunodeficiency virus (FIV) and human immunodeficiency virus (HIV) infection cause similar clinical syndromes of immune dysregulation, opportunistic infections, inflammatory diseases, and neoplasia. Renal disease is the 4th most common cause of death associated with HIV infection. To investigate the association between FIV infection and renal disease in cats. Client-owned cats (153 FIV-infected, 306 FIV-noninfected) and specific-pathogen-free (SPF) research colony cats (95 FIV-infected, 98 FIV-noninfected). A mixed retrospective/prospective cross-sectional study. Blood urea nitrogen (BUN), serum creatinine, urine specific gravity (USG), and urine protein:creatinine ratio (UPC) data were compared between FIV-infected and FIV-noninfected cats. In FIV-infected cats, total CD4+ and CD8+ T lymphocytes were measured using flow cytometry, and CD4+:CD8+ T lymphocyte ratio was calculated. Renal azotemia was defined as a serum creatinine ≥ 1.9 mg/dL with USG ≤ 1.035. Proteinuria was defined as a UPC > 0.4 with an inactive urine sediment. Among the client-owned cats, no association was detected between FIV infection and renal azotemia (P = .24); however, a greater proportion of FIV-infected cats were proteinuric (25.0%, 16 of 64 cats) compared to FIV-noninfected cats (10.3%, 20 of 195 cats) (P < .01). Neither neuter status nor health status were risk factors for proteinuria in FIV-infected cats, but UPC was positively correlated with the CD4+:CD8+ T lymphocyte ratio (Spearman's rho = 0.37, P = .01). Among the SPF research colony cats, no association was detected between FIV infection and renal azotemia (P = .21) or proteinuria (P = .25). Proteinuria but not azotemia was associated with natural FIV infection. Copyright © 2012 by the American College of Veterinary Internal Medicine.

End Stage and Chronic Kidney Disease:Associations with Renal Cancer

Paul eRusso

2012-04-01

Full Text Available There is a well known association between end stage renal disease and the development of kidney cancer in the native kidney of patients requiring renal replacement therapy. There is now emerging evidence that lesser degrees of renal insufficiency (chronic kidney disease, CKD are also associated with an increased likelihood of cancer in general and kidney cancer in particular. Nephro pathological changes are commonly observed in the non tumor bearing portions of kidney resected at the time of partial and radical nephrectomy. In addition, patients with renal cancer are more likely to have CKD at the time of diagnosis and treatment than the general population. The exact mechanism by which renal insufficiency transforms normal kidney cells into tumor cells is not known. Possible mechanisms include uremic immune inhibition or increased exposure to circulating toxins not adequately cleared by the kidneys. Surgeons managing kidney tumors must have an increased awareness of their patient’s renal functional status as they plan their resection. Kidney sparing approaches, including partial nephrectomy or active surveillance in older and morbidly ill patients, can prevent CKD or delay the further decline in renal function which is well documented with radical nephrectomy. Despite emerging evidence that partial nephrectomy provides equivalent local tumor control to radical nephrectomy while at the same time preventing CKD, this operation remains under utilized in the United States and abroad. Increased awareness of the bi directional relationship between kidney function and kidney cancer is essential in the contemporary management of kidney cancer.

Personalized Medicine: New Perspectives for the Diagnosis and the Treatment of Renal Diseases

Anna Gluba-Brzózka

2017-06-01

Full Text Available The prevalence of renal diseases is rising and reaching 5–15% of the adult population. Renal damage is associated with disturbances of body homeostasis and the loss of equilibrium between exogenous and endogenous elements including drugs and metabolites. Studies indicate that renal diseases are influenced not only by environmental but also by genetic factors. In some cases the disease is caused by mutation in a single gene and at that time severity depends on the presence of one or two mutated alleles. In other cases, renal disease is associated with the presence of alteration within a gene or genes, but environmental factors are also necessary for the development of disease. Therefore, it seems that the analysis of genetic aspects should be a natural component of clinical and experimental studies. The goal of personalized medicine is to determine the right drug, for the right patient, at the right time. Whole-genome examinations may help to change the approach to the disease and the patient resulting in the creation of “personalized medicine” with new diagnostic and treatment strategies designed on the basis of genetic background of each individual. The identification of high-risk patients in pharmacogenomics analyses will help to avoid many unwarranted side effects while optimizing treatment efficacy for individual patients. Personalized therapies for kidney diseases are still at the preliminary stage mainly due to high costs of such analyses and the complex nature of human genome. This review will focus on several areas of interest: renal disease pathogenesis, diagnosis, treatment, rate of progression and the prediction of prognosis.

Full Text Available This is a case report on a young patient with severe osteoporosis that was initially revealed when she presented with polyarthralgia during her second pregnancy. Postpartum, the pain increased and her X-ray did not show any abnormalities. A bone scintigraphy was performed. It indicated an inflammatory rheumatic disorder. Six months after partum, an investigation of right coxalgia revealed a spontaneous basicervical fracture. Given the persistent polyarthralgia, the patient underwent a new scintigraphy, which revealed areas of what looked to be old rib and L1 fractures. A subsequent full body magnetic resonance imaging (MRI scan revealed signal abnormalities that could indicate multiple lower limb bone fractures. Despite exhaustive biological, radiological, and histological testing, no secondary cause for the osteoporosis was found. The patient was started on teriparatide. We finally concluded that, despite the atypical presentation, the patient was suffering from postpregnancy osteoporosis. It is possible that the frequency of occurrence of this still poorly understood disease is underestimated.

Full Text Available Although various patterns of renal diseases have been reported from different renal biopsy registries worldwide, data from Nigeria remain scanty. A 10-year retrospective review of renal biopsies was conducted in our tertiary health care facility. All cases were reclassified based on their light microscopic features after the application of standard histochemical stains. A total of 165 cases were reviewed with a male:female ratio of 1.8:1 and a mean age of 15.4 ± 12.0 years. About 69.7% of the cases were below the age of 16 years, while only 2.4% were older than 50 years. The most common indications for biopsy were nephrotic syndrome (72.1% and acute renal failure of unknown etiology (11.5%. Overall, glomerulonephritis (80% was the most common histologic category and occurred only in individuals younger than 50 years old. Minimal change disease (22.9% and membranoproliferative glomerulonephritis (21.9% were the most common varieties in children, while membranous glomerulonephritis (30.6% and focal segmental glomerulosclerosis (27.8% were the commonest among the adult population. The initial histologic diagnosis was revised in 18 cases while a diagnosis was arrived at in seven cases initially adjudged as inadequate for assessment. This study showed that renal biopsy was predominantly performed in children and adolescents. Although glomerulonephritis was the predominant disease, the predominant histologic patterns varied with the patient age. Despite the scarcity of advanced diagnostic tools in resource-poor environments, routine use of histochemical stains is helpful in the evaluation of renal biopsies.

Fasting during the month of Ramadan is one of the five pillars of Islam. During this month, adult Muslims are obligated to refrain from eating and drinking from dawn to dusk. Although based on Islamic principles patients are exempted from fasting, each year, many Muslim patients express their willingness to observe the fast in Ramadan month to respect the cultural customs. There are concerns about the impact of fluid restriction and dehydration during Ramadan fasting for patients with renal diseases. In this study, we reviewed the PubMed, Google Scholar, EBSCO, SCIRUS, Embase, and DOAJ data sources to identify the published studies on the impact of Ramadan fasting on patients with renal diseases. Our review on published reports on renal transplant recipients revealed no injurious effect of Ramadan fasting for the renal graft function. Nearly all studies on this topic suggest that Ramadan fasting is safe when the function of the renal graft is acceptable and stable. Regarding the impact of Ramadan fasting on patients with chronic kidney disease, there is concern about the role of renal hypoperfusion in developing tubular cell injury. Finally, there is controversy between studies about the risk of dehydration in Ramadan in developing renal stones. There are uncertainties about the change in the incidence of renal colic in Ramadan month compared with the other periods of the year. Despite such discrepancies, nearly all studies are in agreement on consuming adequate amounts of water from dusk to dawn to reduce the risk of renal stone formation.

To evaluate the diagnostic efficacy and complications of ultrasound-guided percutaneous renal biopsy using automatic biopsy gun in patients with pediatric diffuse renal disease. Using an 18G automatic biopsy gun, biopsies were performed on 97 pediatric patients with clinically suspicious diffuse renal disease. The acquired tissue specimens were analyzed by photomicroscopy, immunofluorescence, and electron microscopy to support the diagnosis. In the 97 biopsies, the success of the histologic diagnosis, number of glomeruli, and complication rates were retrospectively evaluated by analyzing the variable exams and clinical records. Adequate tissue for histologic diagnosis was obtained in 91 of 97 biopsies (94%) and the mean number of glomeruli was 9.6. Complications such as minute pain, gross hematuria, and small perirenal hematoma presented in 22 of the 97 biopsies (23%), all of which either improved within 5-72 hours or did not need specific treatment. Ultrasound-guided percutaneous renal biopsy using 18G automatic biopsy gun is an effective and safe method for the histologic diagnosis of pediatric diffuse renal disease without any major complication

Communicating about overdiagnosis: Learning from community focus groups on osteoporosis.

Ray Moynihan

Full Text Available Overdiagnosis is considered a risk associated with the diagnosis of osteoporosis-as many people diagnosed won't experience harm from the condition. As yet there's little evidence on community understanding of overdiagnosis outside cancer- where it is an established risk of some screening programs-or effective ways to communicate about it. We examined community understanding around overdiagnosis of osteoporosis, to optimise communication strategies about this problem.Using a qualitative design we recruited a community sample of women, 50-80 years, from the Gold Coast community around Bond University, Australia, using random digit dialing, and conducted 5 focus groups with 41 women. A discussion guide and 4-part presentation were developed and piloted, with independent review from a consumer and clinical experts. Initial discussion had 4 segments: osteoporosis; bone density vs. other risk factors; medication; and overdiagnosis. The second half included the 4 short presentations and discussions on each. Analysis used Framework Analysis method. Initially participants described osteoporosis as bone degeneration causing some fear, demonstrated imprecise understanding of overdiagnosis, had a view osteoporosis couldn't be overdiagnosed as bone scans provided "clear cut" results, expressed belief in early diagnosis, and interest in prevention strategies enabling control. Following presentations, participants expressed some understanding of overdiagnosis, preference for describing osteoporosis as a "risk factor" not "disease", concern about a poor risk-benefit ratio for medications, and surprise and unease the definition of osteoporosis decided bone density of young women was "normal", without age adjustment. Limitations include English-speaking backgrounds of the sample and complex materials.Our findings suggest a gap between community expectations and how experts sometimes arbitrarily set low diagnostic thresholds which label those at risk as "diseased

Osteoporosis in men: epidemiology and treatment with denosumab.

2014-01-01

Osteoporosis is a major public health care concern. Although often described as a disease affecting postmenopausal women, researchers and clinicians have emphasized its prevalence in men in recent years. The National Osteoporosis Foundation has stated that up to 25% of men over the age of 50 years will experience a fracture due to osteoporosis. Men who suffer from a major fracture have higher mortality rates than women. Pharmacologic therapy options for treating osteoporosis are limited for men as compared with women, so each medication approved for use in this population represents an important clinical option. In September 2012, the US Food and Drug Administration approved a new indication for denosumab to increase bone mass in men with osteoporosis at high risk for fracture. Denosumab is a fully human monoclonal antibody and novel antiresorptive agent that works by binding receptor activator of nuclear factor kappa-β ligand (RANKL) and inhibiting the signaling cascade that causes osteoclast maturation, activity, and survival. Ultimately, denosumab suppresses bone turnover and increases bone mineral density in both trabecular and cortical bone. Approval for treating osteoporosis in men was based on data from the ADAMO trial which displayed efficacy in increasing bone mineral density at the lumbar spine, total hip, femoral neck, hip trochanter, and one-third radius. Studies indicate that denosumab is effective and safe, and has superior adherence rates and patient satisfaction. Although long-term data and further research on fracture reduction rates in men should be explored, at this time denosumab is one of several appropriate first-line treatment options for men with osteoporosis.

Osteoporosis and autophagy: What is the relationship?

Directory of Open Access Journals (Sweden)

Rinaldo Florencio-Silva

Full Text Available Summary Autophagy is a survival pathway wherein non-functional proteins and organelles are degraded in lysosomes for recycling and energy production. Therefore, autophagy is fundamental for the maintenance of cell viability, acting as a quality control process that prevents the accumulation of unnecessary structures and oxidative stress. Increasing evidence has shown that autophagy dysfunction is related to several pathologies including neurodegenerative diseases and cancer. Moreover, recent studies have shown that autophagy plays an important role for the maintenance of bone homeostasis. For instance, in vitro and animal and human studies indicate that autophagy dysfunction in bone cells is associated with the onset of bone diseases such as osteoporosis. This review had the purpose of discussing the issue to confirm whether a relationship between autophagy dysfunction and osteoporosis exits.

To assess the knowledge of osteoporosis and evaluation of the practice of osteoporosis preventive measures, among females of reproductive age group. Methodology: A cross-sectional questionnaire based study was undertaken from September 2015 to February 2016 on 174 females (age range 15-49 years) from Military Hospital and Combined Military Hospital, Rawalpindi, Pakistan through non- probability convenient sampling. Females with any metabolic, muscular or diagnosed bone disease were excluded from the study. The self -administered questionnaire consisted of questions regarding basic demographics, knowledge and practice of preventive factors related to osteoporosis. Result: Majority (86.8%) females knew about osteoporosis. 80% considered major risk factor to be low calcium intake. Regarding practices, 44.3% of women practiced daily intake of milk in their diet, 69.5 % females practiced physical activity like walking on daily basis and 65.5% have direct exposure of sunlight but only 12.1% of women used calcium supplements. Conclusion: The study revealed that majority of the women knew about osteoporosis and its risk factors but many of them were not practicing appropriate lifestyle and dietary habits to decrease their risk of osteoporosis. Thus, there is a need of standardized approach to promote healthy behaviors to decrease the risk of osteoporosis before menopause. (author)

The United States Renal Data System (USRDS) began in 1989 through US Congressional authorization under National Institutes of Health competitive contracting. Its history includes five contract periods, two of 5 years, two of 7.5 years, and the fifth, awarded in February 2014, of 5 years. Over these 25 years, USRDS reporting transitioned from basic incidence and prevalence of end-stage renal disease (ESRD), modalities, and overall survival, as well as focused special studies on dialysis, in the first two contract periods to a comprehensive assessment of aspects of care that affect morbidity and mortality in the second two periods. Beginning in 1999, the Minneapolis Medical Research Foundation investigative team transformed the USRDS into a total care reporting system including disease severity, hospitalizations, pediatric populations, prescription drug use, and chronic kidney disease and the transition to ESRD. Areas of focus included issues related to death rates in the first 4 months of treatment, sudden cardiac death, ischemic and valvular heart disease, congestive heart failure, atrial fibrillation, and infectious complications (particularly related to dialysis catheters) in hemodialysis and peritoneal dialysis patients; the burden of congestive heart failure and infectious complications in pediatric dialysis and transplant populations; and morbidity and access to care. The team documented a plateau and decline in incidence rates, a 28% decline in death rates since 2001, and changes under the 2011 Prospective Payment System with expanded bundled payments for each dialysis treatment. The team reported on Bayesian methods to calculate mortality ratios, which reduce the challenges of traditional methods, and introduced objectives under the Health People 2010 and 2020 national health care goals for kidney disease.

Full Text Available A 15-month-old girl, born to the consanguineous parents, was referred with the sign of massive splenomegaly associated with thrombocytopenia and anemia. Plasma Chitotriosidase estimation was carried out as a screening test and was found to be normal with reduced activity of β-glucosidase in leucocytes suggestive of Gaucher disease. At the age of 4 years, severe osteoporosis and cardiomegaly with pulmonary congestion were observed in the child. Molecular analysis for GBA gene has revealed homozygous status for L444P (c.1448C in the proband, whereas parents and two elder sisters were found to be heterozygote. Prenatal study during the fourth pregnancy was carried out from cultured chorionic villi for β-glucosidase, which was in the carrier range. Further confirmation of the carrier status was carried out from amniotic fluid DNA and was found to be heterozygous for L444P (c.1448C in the GBA gene. This case demonstrates that children with the sign of splenomegaly with anemia and thrombocytopenia need to be screened for Gaucher disease, and molecular study can further help to confirm the heterozygous status, where prenatal study by enzyme investigation demonstrate heterozygous condition.

Full Text Available Kristel M Sidlauskas, Emily E Sutton, Michael A Biddle Albany College of Pharmacy and Health Sciences-Vermont Campus, Colchester, VT, USA Abstract: Osteoporosis is a major public health care concern. Although often described as a disease affecting postmenopausal women, researchers and clinicians have emphasized its prevalence in men in recent years. The National Osteoporosis Foundation has stated that up to 25% of men over the age of 50 years will experience a fracture due to osteoporosis. Men who suffer from a major fracture have higher mortality rates than women. Pharmacologic therapy options for treating osteoporosis are limited for men as compared with women, so each medication approved for use in this population represents an important clinical option. In September 2012, the US Food and Drug Administration approved a new indication for denosumab to increase bone mass in men with osteoporosis at high risk for fracture. Denosumab is a fully human monoclonal antibody and novel antiresorptive agent that works by binding receptor activator of nuclear factor kappa-β ligand (RANKL and inhibiting the signaling cascade that causes osteoclast maturation, activity, and survival. Ultimately, denosumab suppresses bone turnover and increases bone mineral density in both trabecular and cortical bone. Approval for treating osteoporosis in men was based on data from the ADAMO trial which displayed efficacy in increasing bone mineral density at the lumbar spine, total hip, femoral neck, hip trochanter, and one-third radius. Studies indicate that denosumab is effective and safe, and has superior adherence rates and patient satisfaction. Although long-term data and further research on fracture reduction rates in men should be explored, at this time denosumab is one of several appropriate first-line treatment options for men with osteoporosis.

Superovulation procedures and assisted reproductive technologies have been widely used to treat couples who have infertility problems. Although generally safe, the superovulation procedures are associated with a series of complications, such as ovarian hyper-stimulation syndrome, thromboembolism, and adnexal torsion. The role of long-term repeated superovulation in ovarian aging and especially in associated disorders such as osteoporosis and cardiovascular diseases is still unclear. In this study, we sought to determine if repeated superovulation by ten cycles of treatment with pregnant mare serum gonadotropin/human chorionic gonadotropin could affect ovarian reserve, ovarian function, bone density and heart function. Ovarian reserve and function were reflected by the size of the primordial follicle pool, anti-Mullerian hormone expressions, hormone levels and fertility status. Furthermore, we examined bone density and heart function by microCT and cardiovascular ultrasonography, respectively. After repeated superovulation, the size of the primordial follicle pool and the expression of anti-mullerian hormone decreased, along with the concentrations of estrogen and progesterone. Mice exposed to repeated superovulation showed an obvious decrease in fertility and fecundity. Furthermore, both bone density and heart ejection fraction significantly decreased. These results suggest that repeated superovulation may increase the risk of osteoporosis and cardiovascular diseases by accelerating ovarian aging.

Full Text Available Background/Aim. Drug-related problems are especially frequent among patients suffering from non-communicable diseases, like osteoporosis, leading to suboptimal treatment response. The aim of this study was to identify drug-related problems in patients with osteoporosis. Methods. This cross-sectional prospective study was conducted in January 2014 on outpatients with osteoporosis from three health facilities in Belgrade, Serbia. The patients included in the study were older than 50 years, and they were offered an anonymous questionnaire with open-ended questions. Results. There were 355 study participants, 329 (92.7% females and 26 (7.3% males. The patients who experienced at least one osteoporotic fracture (n = 208 were significantly less adherent to the therapy, less engaged in sports and regular physical activities, and more prone to nutrition with inadequate intake of calcium and vitamin D than patients without fractures (n = 147. Conclusion. The effectiveness of osteoporosis treatment is decreased by several drug-related problems encountered by both physicians and patients. However, the majority of the drug-related problems could be greatly influenced by appropriate educational programs. [Projekat Ministarstva nauke Republike Srbije, br. 175007

Low serum and bone vitamin K status in patients with longstanding Crohn's disease: another pathogenetic factor of osteoporosis in Crohn's disease?

BACKGROUND—A high prevalence of osteoporosis is reported in Crohn's disease. The pathogenesis is not completely understood but is probably multifactorial. Longstanding Crohn's disease is associated with a deficiency of fat soluble vitamins, among them vitamin K. Vitamin K is a cofactor in the carboxylation of osteocalcin, a protein essential for calcium binding to bone. A high level of circulating uncarboxylated osteocalcin is a sensitive marker of vitamin K deficiency.
AIMS—To determine serum and bone vitamin K status in patients with Crohn's disease and to elucidate its relationship with bone mineral density.
METHODS—Bone mineral density was measured in 32 patients with longstanding Crohn's disease and small bowel involvement, currently in remission, and receiving less than 5 mg of prednisolone daily. Serum levels of vitamins D and K, triglycerides, and total immunoreactive osteocalcin, as well as uncarboxylated osteocalcin ("free" osteocalcin) were determined. The hydroxyapatite binding capacity of osteocalcin was calculated. Data were compared with an age and sex matched control population.
RESULTS—Serum vitamin K levels of CD patients were significantly decreased compared with normal controls (p<0.01). "Free" osteocalcin was higher and hydroxyapatite binding capacity of circulating osteocalcin was lower than in matched controls (p<0.05 and p<0.001, respectively), indicating a low bone vitamin K status in Crohn's disease. In patients, an inverse correlation was found between "free" osteocalcin and lumbar spine bone mineral density (r=−0.375, p<0.05) and between "free" osteocalcin and the z score of the lumbar spine (r=−0.381, p<0.05). Multiple linear regression analysis showed that "free" osteocalcin was an independent risk factor for low bone mineral density of the lumbar spine whereas serum vitamin D was not.
CONCLUSIONS—The finding that a poor vitamin K status is associated with low bone mineral density in longstanding Crohn

Control of hypertension is often a problem in the management of end stage renal disease (ESRD). Multiple modalities of treatment are required to prevent cardiovascular and cerebrovascular mortality and morbidity. These include fluid and salt restriction, multidrug regimes and dialysis. We report a case of young 25 years old patient, admitted with chronic renal failure, complicated by malignant and refractory hypertension, not responding to hemodialysis and antihypertensive agent. During stay in hospital, patient also had intracerebral hemorrhage, fits due to uncontrolled hypertension requiring ventilatory support followed. Renal transplant was considered to be the final therapeutic modality. After gradual recovery, a successful live-related renal transplant was performed. As soon as good graft was established, the blood pressure settled and 4 of the 5 antihypertensives were withdrawn. After 2 weeks, patient was discharged in a stable condition with a total stay of about 2 months. (author)

To compare the RI (resistive index) of renal artery with serum creatinine level and histological change in 50 patients with renal parenchymal disease. To measure RI in each patient, Doppler studies were performed three times in each kidney at the level of the interlobar arteries, and the average value of RI was taken. The study was performed 1 -3 days after renal biopsy and the time interval between blood sampling for serum creatinine and duplex study was also 1 - 3 days. The RI of patients with renal disease was also correlated with patient's age, sex and serum creatinine level, and RI was also correlated with the degree of severity of glomerular, interstitial, and vascular change in the kidneys. Statistical analysis was performed using Student's t test and Pearson's correlation method. The RI of the normal control and renal disease group was 0.566±0.037 and 0.584±0.038, respectively with no statistical significance(p=0.444). In the group with renal disease, there was no significant correlation between RI and a patient's age, sex, and serum creatinine level(p>0.05). RI was not significantly different between predominantly glomerular disease (n=45) and nonglomerular or mixed disease(n=5)(p=0.558), and did not correlate with the severity of glomerular sclerosis, interstitial fibrosis, or atherosclerosis(p>0.05). The authors conclude that RI is not helpful for the diagnosis and differential diagnosis of renal parenchymal diseases and does not correlate with serum creatinine levels. In order to define the role of the RI, further clinical experience with more cases is required

Full Text Available Osteoporosis is the most frequent systemic disease of the bone, that affects elderly, mainly women in menopause. It can be defined by lowering of bone mass and microarchitectural deterioration of the bone tissue, resulting in an increased bone fragility. Main complications of osteoporosis are fractures of the vertebrae, hips and forearm. In view of its large variety of causes and manifestations, diagnostic and therapeutical approach in osteoporosis represents a multidisciplinary issue. The accurate diagnosis of osteoporosis is based on a method that measures the bone mineral density, expressed by the T-score, using dual energy X-ray absorptiometry, so called DXA. Lately, in practice in order for establishing the risk of osteoporosis and osteoporotic fracture the FRAX tool is increasingly used (The Fracture Risk Assessment. Treatment of osteoporosis is complex involving non-pharmacological and pharmacological measures. Non-pharmacological methods include preventive measures like exercise, external hip protectors, increase of dietary intake of calcium, vitamin D and proteins, especially in elderly, over 65 years. Pharmacological measures are represented by different types of drugs, including biphosphonates, bone formation stimulatory drugs, agents with new mechanisms of action, hormone replacement therapy and they will be indicated only after a detailed clinical and paraclinical examination of the patient. Regardless of the chosen pharmacological measure, periodical follow-up of efficacy, side-effects and complications of antiosteoporotic treatment, by clinical examination and laboratory investigations targeting bone remodelling, is strongly indicated.

Osteoporosis is a common disease of the elderly, in which genetic and clinical factors contribute to the disease phenotype. Since the production of interleukin-1 (IL-1) has been implicated in the bone mass and skeletal disorders, we investigated whether IL-1 system gene polymorphisms are associated with the pathogenesis of osteoporosis in postmenopausal Taiwanese women.Osteoporosis is diagnosed by dual-energy x-ray absorptiometry, which measures bone mineral density (BMD) at multiple skeletal sites. We studied the IL-1a (-889C/T), IL-1 (-511C/T) and the 86 base pair variable number tandem repeat (VNTR) in intron 2 of the IL-1 receptor antagonist (IL-1ra) gene in 117 postmenopausal women with osteoporosis and 135 control subjects without a history of symptomatic osteoporosis. These gene polymorphisms were analyzed by polymerase chain reaction and restriction fragment length polymerase. Blood sugar and other risk factors were also determined.The frequencies of IL-1 (-511C/T) genotypes (P=.022, odds ratio=1.972) and alleles (P=.02, odds ratio=2.909) showed a statistically significant difference between the two groups. However, we did not find any statistically significant difference in IL-1 and IL-1ra polymorphisms (P>.05). We also observed a positive relationship between osteoporosis and cholesterol and a weak inverse relationship between blood sugar and osteoporosis in postmenopausal women.These experimental results suggest that the pathogenesis of osteoporosis is associated with IL-1 (-511C/T) polymorphism in postmenopausal women. This polymorphism is an independent risk factor for osteoporosis (Author).

This large-scale post-marketing surveillance study was conducted to assess the safety and effectiveness of eldecalcitol treatment in patients with osteoporosis in a Japanese clinical setting. A total of 3567 patients with osteoporosis were enrolled and received eldecalcitol 0.75 μg/day for 12 months. For this interim report, 3285 patients were eligible for analysis. Mean age was 74.9 ± 8.7 years; 86.8 % (2854/3285) were women. There were 142 reported adverse drug reactions (ADRs) in 129 patients (3.92 % of the total 3285 patients): the most common were hypercalcemia and increased blood calcium (0.88 %), renal impairment (0.27 %), abdominal discomfort (0.24 %), constipation (0.24 %), and pruritus (0.24 %). The incidence of ADRs was 5.10 % in men and 3.74 % in women. Although 10 serious ADRs were reported in 9 patients (0.27 %), no clinically significant safety issues were identified. Incidence of hypercalcemia or increased blood calcium was 8.47 % in patients with renal impairment and only 0.74 % in patients without renal impairment. At last observation, the incidence of new vertebral and nonvertebral fractures was 2.44 % and 1.70 %, respectively. There was a significant increase in bone mineral density at the lumbar spine and distal radius. The bone turnover markers BAP, serum NTX, urinary NTX, and TRACP-5b were suppressed by eldecalcitol treatment in both sexes. In conclusion, consistent with the findings of the phase III pivotal clinical trial, eldecalcitol was shown to have a favorable safety profile and effectiveness in Japanese patients with osteoporosis. However, periodic measurements of serum calcium were required to prevent occurrence of hypercalcemia during eldecalcitol treatment, especially in patients with renal impairment.

Osteoporosis is a major cause of morbidity and mortality in both men and women. The mortality rate in men within 1 year of hip fracture is 37.5%, which is 51% higher than in women. Although clear guidelines exist for osteoporosis screening in women, these are less clear for men. The available guidelines recommend screening high-risk men; however, screening does not appear to be a standard practice. To increase screening rates of osteoporosis in high-risk men in our primary care clinic by 50%. The screening rate of osteoporosis was determined in high-risk male veterans more than 50 years of age enrolled in the resident physician- and nurse practitioner-staffed primary care clinics at a Veterans Affairs Medical Center in Cleveland, OH. High-risk factors included prolonged use of steroids; hypogonadism; and autoimmune diseases such as rheumatoid arthritis, inflammatory bowel disease, and systemic lupus erythematosus, which are known to be associated with osteoporosis. We surveyed health care professional trainees and nurses to explore their barriers to screening for osteoporosis in high-risk men. After creating awareness about the importance of this condition among the health care professionals, we analyzed whether this education had any impact on the screening rate. The baseline screening rate in high-risk men was 11%. After phased surveys and awareness building, the screening rate increased to 20%. Osteoporosis in high-risk men is under-screened. Creating more awareness about the impact of this condition among health professional trainees and nurses can lead to improved screening rates.

Autosomal dominant polycystic kidney disease (ADPKD) is one of the often seen (from 1:400 to 1:1000) inherited renal diseases with serious prognosis. The exact diagnosis, earlier treatment of the urinary tract infections and hypertension were the steps for prevention of the renal disease progression. The abdominal ultrasound is method used for screening. The frequency of the renal tumors in general population was not higher compared to those in patients with ADPKD. We described and discussed the results obtained by different imaging techniques in 23 years old female with family history for ADPKD. She was admitted to the 'Alexandrovska' University Hospital Nephrology Clinic because of the recurrence of the urinary tract infection. The diagnosis of renal tumor was suspected by renal intravenous pyelography (IVP). All the others imaging techniques - Triplex sonography-B-mode, Color, Pulse, Power Doppler, Tissue Doppler as well as contrast computer tomography showed the polycystic kidney disease, without focal changes, with several small cysts based in the medulla near distal calyces. This was probably the reason for the false-positive image made by IVP. The diagnostic values of the different imaging techniques in making the exact diagnosis in patients with polycystic kidney disease were comment, as well as a peculiar ultrasound image of the polycystic kidney in young patients, aged less then 30 years. To make the correct diagnosis of ADPKD the combination of all known imaging techniques was needed. The small kidney tumors were better visualized by tissue-harmonic ultrasound

Pharmacological treatment of osteoporosis in the oldest old

Consequently, the global prevalence of osteoporotic fractures will increase with the aging of the population. In old age, osteoporosis is associated with a substantial burden in terms of morbidity and mortality. Nevertheless, osteoporosis in old age continues to be underdiagnosed and undertreated. This may, at least partly, be explained by the fact that evidence of the antifracture efficacy of osteoporosis treatments comes mainly from randomized controlled trials in postmenopausal women with a mean age of 70–75 years. However, in the last years, subgroup analyses of these landmark trials have been published investigating the efficacy and safety of osteoporosis treatment in the very elderly. Based on this evidence, this narrative review discusses the pharmacological management of osteoporosis in the oldest old (≥80 years. Because of the high prevalence of calcium and/or vitamin D deficiency in old age, these supplements are essential in the management of osteoporosis in the elderly people. Adding antiresorptive or anabolic treatments or combinations, thereof, reduces the risk of vertebral fractures even more, at least in the elderly with documented osteoporosis. The reduction of hip fracture risk by antiresorptive treatments is less convincing, which may be explained by insufficient statistical power in some subanalyses and/or a higher impact of nonskeletal risk factors in the occurrence of hip fractures. Compared with younger individuals, a larger absolute risk reduction is observed in the elderly because of the higher

Pancreatitis with normal lipase and amylase level is a rare phenomenon. This is especially true in patient with end-stage renal disease as lipase and amylase are renally excreted. Literature review reveals previous case report of pancreatitis with normal lipase and amylase level, however, none of them occurred in the setting of end-stage renal disease. Our case is the first such reported case of pancreatitis in such setting. Here we report a 30year old male with past medical history of end-stage renal disease who presented in emergency department with acute abdominal pain. Laboratory work up revealed normal lipase and amylase level. However, radiological work up was consistent with pancreatitis. This case report highlight the importance of taking the overall clinical picture rather than laboratory work up to rule in or rule out the diagnosis of pancreatitis. Furthermore, this should also serve an important reminder for clinicians to further investigate where clinical suspicion for pancreatitis is high. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Background. Osteoporosis is an extrapulmonary effect of chronic obstructive pulmonary disease (COPD. Diagnosis of osteoporosis is based on BMD measured by DXA-scan. The best location for BMD measurement in COPD has not been determined. Aim of this study was to assess whole-body BMD and BMD of the hip and lumbar spine (local DXA in COPD patients and compare the prevalence of osteoporosis at these locations. Methods. Whole body as well as local DXA-scan were made in 168 COPD patients entering pulmonary rehabilitation. Patient-relevant characteristics were assessed. Prevalence of osteoporosis was determined. Characteristics of patients without osteoporosis were compared to patients with osteoporosis on local DXA. Results. A higher prevalence of osteoporosis was found using local DXA compared to whole-body DXA (39% versus 21%. One quarter of patients without osteoporosis on whole body-DXA did have osteoporosis on local DXA. Significant differences in patient characteristics between patients without osteoporosis based on both DXA measurements and patients with osteoporosis based on local DXA only were found. Conclusions. DXA of the hip and lumbar spine should be made to assess bone mineral density in COPD patients. The lowest T-score of these locations should be used to diagnose osteoporosis.

Full Text Available Abstract Background Medical management is the conventional treatment for Stanford Type B aortic dissections as surgery is associated with significant morbidity and mortality. The advent of endovascular interventional techniques has revived interest in treating end-organ complications of Type B aortic dissection. We describe a patient who benefited from endovascular repair of renal artery stenosis caused by a dissection flap, which resulted in reversal of his end-stage renal disease (ESRD. Case presentation A 69 y/o male with a Type B aortic dissection diagnosed two months earlier was found to have a serum creatinine of 15.2 mg/dL (1343.7 μmol/L on routine visit to his primary care physician. An MRA demonstrated a rightward spiraling aortic dissection flap involving the origins of the celiac artery, superior mesenteric artery, and both renal arteries. The right renal artery arose from the false lumen with lack of blood flow to the right kidney. The left renal artery arose from the true lumen, but an intimal dissection flap appeared to be causing an intermittent stenosis of the left renal artery with compromised blood flow to the left kidney. Endovascular reconstruction with of the left renal artery with stent placement was performed. Hemodialysis was successfully discontinued six weeks after stent placement. Conclusion Percutaneous intervention provides a promising alternative for patients with Type B aortic dissections when medical treatment will not improve the likelihood of meaningful recovery and surgery entails too great a risk. Nephrologists should therefore be aggressive in the workup of ischemic renal failure associated with aortic dissection as percutaneous intervention may reverse the effects of renal failure in this population.

Renal denervation represents an emerging treatment for resistant hypertension in patients with end-stage renal disease, but data about the anatomic substrate of this treatment are lacking. Therefore, the aim of this study was to investigate the morphological basis of sympathetic hyperactivity in the setting of hemodialysis patients to identify an anatomical substrate that could warrant the use of this new therapeutic approach. The distribution of sympathetic nerves was evaluated in the adventitia of 38 renal arteries that were collected at autopsy or during surgery from 25 patients: 9 with end-stage renal disease on dialysis (DIAL group) and 16 age-matched control nondialysis patients (CTRL group). Patients in the DIAL group showed a significant increase in nerve density in the internal area of the peri-adventitial tissue (within the first 0.5 mm of the beginning of the adventitia) compared with the CTRL group (4.01±0.30 versus 2.87±0.28×mm(2), P=0.01). Regardless of dialysis, hypertensive patients with signs of severe arteriolar damage had a greater number of nerve endings in the most internal adventitia, and this number was significantly higher than in patients without hypertensive arteriolar damage (3.90±0.36 versus 2.87±0.41×mm(2), P=0.04), showing a correlation with hypertensive arteriolar damage rather than with hypertensive clinical history. The findings from this study provide a morphological basis underlying sympathetic hyperactivity in patients with end-stage renal disease and might offer useful information to improve the use of renal denervation in this group of patients. © 2015 The Authors.

Full Text Available The purpose of this study was to evaluate periodontal disease (PD in dogs with chronic renal failure (CRF and to compare it to PD in dogs with normal renal function (NRF. Twelve dogs with CRF and 24 dogs with NRF, all presenting dental pocket formation, were compared. In all dogs, serum creatinine, blood urea nitrogen, urine specific gravity and total red and white blood cells were determined. A complete oral examination was also performed including evaluation of bacterial plaque, gingivitis, gingival recession, pocket, calculus, dental mobility, dental loss, and ulcers. These data were used to calculate plaque index (PI, gingival index (GI and periodontal destruction index (PDI. PD was graded as mild, moderate or severe based on the results. Mild, moderate or severe PD was observed in dogs with NRF, whereas dogs with CRF presented either mild or severe PD. Dogs with NRF showed higher involvement of the maxillary teeth, whereas dogs with CRF showed a higher involvement of the mandibular teeth. Plaque index was significantly higher in dogs with NRF. It was concluded that lesion distribution and periodontal disease progression may be altered in dogs with CRF, and gingival inflammatory response differs in dogs with NRF and CRF regarding to the stage of periodontal disease.

Osteoporosis, or bone loss, is a progressive, systemic skeletal disease that affects millions of people worldwide. Osteoporosis is generally age related, and it is underdiagnosed because it remains asymptomatic for several years until the development of fractures that confine daily life activities, particularly in elderly people. Most patients with osteoporotic fractures become bedridden and are in a life-threatening state. The consequences of fracture can be devastating, leading to substantial morbidity and mortality of the patients. The normal physiologic process of bone remodeling involves a balance between bone resorption and bone formation during early adulthood. In osteoporosis, this process becomes imbalanced, resulting in gradual losses of bone mass and density due to enhanced bone resorption and/or inadequate bone formation. Several growth factors underlying age-related osteoporosis and their signaling pathways have been identified, such as osteoprotegerin (OPG)/receptor activator of nuclear factor B (RANK)/RANK ligand (RANKL), bone morphogenetic protein (BMP), wingless-type MMTV integration site family (Wnt) proteins and signaling through parathyroid hormone receptors. In addition, the pathogenesis of osteoporosis has been connected to genetics. The current treatment of osteoporosis predominantly consists of antiresorptive and anabolic agents; however, the serious adverse effects of using these drugs are of concern. Cell-based replacement therapy via the use of mesenchymal stem cells (MSCs) may become one of the strategies for osteoporosis treatment in the future.

Human immunodeficiency virus (HIV) is associated with several renal syndromes including acute and chronic renal failures, but the underlying pathogenic mechanisms are unclear. HIV and feline immunodeficiency virus (FIV) share numerous biological and pathological features, including renal alterations. We investigated and compared the morphological changes of renal tissue of 51 experimentally and 21 naturally infected cats. Compared to the latter, the experimentally infected cats exhibited some mesangial widening and glomerulonephritis, milder proteinuria, and lower tubular and interstitial alterations. The numbers of giant protein tubular casts and tubular microcysts were also lower. In contrast, diffuse interstitial infiltrates and glomerular and interstitial amyloidosis were detected only in naturally infected cats. Similar alterations are found in HIV infected patients, thus supporting the idea of a causative role of FIV infection in renal disease, and underlining the relevance of the FIV and its natural host as an animal model for investigating lentivirus-associated nephropathy.

Full Text Available A osteoporose é uma doença ósteo-metabólica que atinge especialmente mulheres após a menopausa. Segundo a Organização Mundial de Saúde 1/3 das mulheres brancas acima dos 65 anos são portadoras de osteoporose. Entretanto estima-se que um homem branco de 60 anos tenha 25 % de chance de ter uma fratura osteoporótica. O diagnóstico e planejamento terapêutico são baseados na densitometria óssea e na dosagem laboratorial dos marcadores de formação e reabsorção óssea. A densitometria também é o melhor preditor de fraturas. Os medicamentos atualmente disponíveis atuam mais na inibição da reabsorção óssea. A principal forma de tratamento da osteoporose é a prevenção: deve-se evitar o fumo; álcool e café devem ser consumidos com moderação; a atividade física e ingestão adequada de cálcio são fundamentais; o treinamento proprioceptivo pode colaborar para prevenir quedas e, conseqüentemente, as fraturas.Osteoporosis is an osteometabolic disease affecting mainly postmenopausal women. According to the World Health Organization, 1/3 of older than 65 white women are affected by osteoporosis. Notwithstanding, the estimates say that 60-year old white males have a 25% chance of osteoporotic fractures. Diagnosis and the therapeutic design are based on bone densitometry and laboratory determinations of formation and bone reabsorption markers. Densitometry is the best fracture predictor. Currently available drugs act inhibiting bone reabsorption. The main form of treatment of osteoporosis is prevention: smoking must be avoided; alcohol and coffee drinking must be moderate; physical activity and adequate calcium intake are fundamental; proprioceptive training can prevent falls and, consequently, fractures.

Introduction: Atherosclerosis and osteoporosis; Cause the majority of morbidity and mortality in older adults and their prevalence continues to increase. The clinical coincidence of vascular disease and osteoporosis indicates that there are common mediators that adversely affect and resemble bone metabolism and vascular integrity. Atherosclerosis and osteoporosis are part of a shared diagnosis. We intend to work with the use of two combined imaging techniques to precociously assess the state of bone mass in patients with advanced neoplasia who live with osteoporosis and atherosclerosis in order to be able to take appropriate medical and therapeutic behaviors that help to improve the quality of life of these patients. Purpose: To determine the morpho functional status of bone in patients with osteoporosis and atherosclerosis with metastatic bone disease, through two noninvasive and combined imaging techniques, at different stages of disease progression. Method: A prospective, descriptive and longitudinal study will be carried out on 100 patients referred from the Orthopedics and Oncology Service of the Frank Paíz Hospital and the Oncology Institute, with a confirmed diagnosis of metastatic neoplastic disease in bones and with a history of osteoporosis and Vascular arteriosclerosis, or with clinical suspicion of them. With ages between 35 and 60 years and both sexes. In the period between 2010 and 2014. The BMD values will be determined through Densitometry at the lumbo-sacral column and hips level, at the beginning, at six months and at the first year, in each of the patients . Bone scintigraphy with MDP will also be performed at the beginning, six months and the year of the first one performed equally on all patients in the sample.

Osteoporosis is being increasingly recognised in paediatric practice as a consequence of the increasing life expectancy of children who suffer from chronic diseases and other factors. There are many non-pharmacological measures that can improve children' bone health, for example, avoiding inflammatory activity and osteotoxic treatments; increasing sun exposure and weight-bearing exercise, and maintaining an adequate nutritional status. Vitamin D and calcium supplements have been proposed as a measure to increase bone mass, but their effect and therapeutic indications are not completely clear. On the other hand, bisphosphonates are currently the only pharmacological alternative for the patients with infantile secondary osteoporosis. However, more studies are required on the therapeutic indications, posology, and long term secondary effects of biphosphonates. The aim of this article is to analyze the scientific evidence of the effectiveness of the therapeutic alternatives for childhood secondary osteoporosis and their safety in children.

Inpatient and outpatient management and treatment of fractures can be costly. With more emphasis placed on quality care for Medicare beneficiaries, we studied if patients were receiving proper screening for osteoporosis and treatment after diagnosis of fracture. This study aims to determine if adequate screening and treatment for osteoporosis occurs in the postfracture period.Methods: A retrospective analysis of Medicare beneficiaries aged 67 years or older was gathered from a single institution in both inpatient and outpatient visits. Based on International Classification of Diseases ninth revision codes, primary diagnosis of fractures of neck and trunk, upper limb, and lower limb were obtained in addition to current procedural terminology codes for fracture procedures. We studied patients who had been screened for osteoporosis with a bone mineral study or received osteoporosis treatment after their fracture.Results: Medicare beneficiaries totaling 1,375 patients were determined to have an inclusion fracture between June 1, 2013 and November 30, 2014. At the time of our analysis on December 1, 2014, 1,219 patients were living and included in the analysis.

Alport syndrome results from mutations in either the alpha3(IV), alpha4(IV), or alpha5(IV) collagen genes. The disease is characterized by a progressive glomerulonephritis usually associated with a high-frequency sensorineural hearing loss. A mouse model for an autosomal form of Alport syndrome [collagen alpha3(IV) knockout] was produced and characterized. In this study, the model was exploited to demonstrate a potential role for transforming growth factor-beta1 (TGF-beta1) in Alport renal disease pathogenesis. Kidneys from normal and Alport mice, taken at different stages during the course of renal disease progression, were analyzed by Northern blot, in situ hybridization, and immunohistology for expression of TGF-beta1 and components of the extracellular matrix. Normal and Alport human kidney was examined for TGF-beta1 expression using RNase protection. The mRNAs encoding TGF-beta1 (in both mouse and human), entactin, fibronectin, and the collagen alpha1(IV) and alpha2(IV) chains were significantly induced in total kidney as a function of Alport renal disease progression. The induction of these specific mRNAs was observed in the glomerular podocytes of animals with advanced disease. Type IV collagen, laminin-1, and fibronectin were markedly elevated in the tubulointerstitium at 10 weeks, but not at 6 weeks, suggesting that elevated expression of specific mRNAs on Northern blots reflects events associated with tubulointerstitial fibrosis. The concomitant accumulation of mRNAs encoding TGF-beta1 and extracellular matrix components in the podocytes of diseased kidneys may reflect key events in Alport renal disease progression. These data suggest a role for TGF-beta1 in both glomerular and tubulointerstitial damage associated with Alport syndrome.

Full Text Available Adrenocorticotrophin (ACTH-secreting pituitary adenoma, also known as Cushing disease (CD, is rare and causes metabolic syndrome, cardiovascular disease and osteoporosis due to hypercortisolism. However, the molecular pathogenesis of CD is still unclear because of a lack of human cell lines and animal models. Here, we study 106 clinical characteristics and gene expression changes from 118 patients, the largest cohort of CD in a single-center. RNA deep sequencing is used to examine genotypic changes in nine paired female ACTH-secreting pituitary adenomas and adjacent nontumorous pituitary tissues (ANPT. We develop a novel analysis linking disease clinical characteristics and whole transcriptomic changes, using Pearson Correlation Coefficient to discover a molecular network mechanism. We report that osteoporosis is distinguished from the phenotype and genotype analysis. A cluster of genes involved in osteoporosis is identified using Pearson correlation coefficient analysis. Most of the genes are reported in the bone related literature, confirming the feasibility of phenotype-genotype association analysis, which could be used in the analysis of almost all diseases. Secreted phosphoprotein 1 (SPP1, collagen type I α 1 chain (COL1A1, 5′-nucleotidase ecto (NT5E, HtrA serine peptidase 1 (HTRA1 and angiopoietin 1 (ANGPT1 and their signalling pathways are shown to be involved in osteoporosis in CD patients. Our discoveries provide a molecular link for osteoporosis in CD patients, and may open new potential avenues for osteoporosis intervention and treatment.

Breastfeeding and postmenopausal osteoporosis.

Bone loss associated with osteoporosis occurs with high frequency among the elderly and often results in debilitating fractures. A combination of lifestyle behaviors, genetic predisposition, and disease processes contributes to bone metabolism. Therefore, any discussion regarding bone health must address these factors. The impact of menopause on bone turnover has been generally well studied and characterized. Breastfeeding places significant stress on calcium metabolism and, as a consequence, directly influences bone metabolism. The most significant factors affecting bone mineral density (BMD) and bone metabolism are the duration and frequency of lactation, the return of menses, and pre-pregnancy weight. Although transient, lactation is associated with bone loss. As clinical guidelines and public health policies are being formulated, there is a compelling need for further investigation into the relationship of lactation, BMD, and subsequent risk of osteoporosis. Better understanding of this relationship will provide new opportunities for early intervention and ultimately help in the prevention of bone loss in postmenopausal women.

The synthetic drug fenoldopam mesylate (FM) may have a renoprotective role, and a "renal dose" of 0.1 µg/kg/min intravenous (IV) infusion of FM has been reported as able to increase renal blood flow without affecting systemic blood pressure. But conclusive data are still lacking. We aimed to investigate by color-Doppler ultrasonography the effects of IV administration of FM at this dosage in hypertensive chronic kidney disease (CKD) patients, and verify whether it may induce any systemic hemodynamic alteration. In 60 hypertensive CKD patients, we measured by duplex Doppler ultrasonography, at baseline and during infusion of 0.1 µg/kg/min of FM, the systolic and diastolic flow velocity (sampled at the renal hilum, intermediate section and origin of both renal arteries) and the intra-parenchymal renal resistive index (RRI) sampled on interlobular arteries of both kidneys. Patients were divided into four subgroups (I-IV) according to classification of National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF-DOQI). Infusion of 0.1 µg/kg/min FM significantly decreased the RRI (0.73 ± 0.05 vs. 0.65 ± 0.06; p flow velocities in all renal artery tracts examined. No single episode of systemic hypotension was observed. Very low-dose FM may significantly increase renal blood flow and exert a renal protective effect in hypertensive CKD patients. Infusion of FM at such low dosage appears also to be quite safe, even in CKD and hypertensive patients.

Aim: To assess the performance of diffusion-weighted magnetic resonance imaging (MRI) for the assessment of renal fibrosis in chronic kidney disease (CKD), with histopathology as a reference standard. Materials and methods: Forty patients with CKD and 30 healthy volunteers were recruited for the study. All participants underwent diffusion-weighted MRI. Renal biopsy was performed in 25 patients with CKD. Mean renal medullary and cortical apparent diffusion coefficient (ADC) values were compared between CKD patients and the healthy volunteers. Pearson's correlation coefficient was calculated to investigate the relationship between ADC values, serum creatinine (SCr), estimated glomerular filtration rate (eGFR), 24 h urinary protein (24h-UPRO), and renal histopathological scores. Results: Cortical and medullary ADC values in the CKD group were significantly lower compared to those in the healthy controls. In the CKD group, a significant negative correlation was found between cortical ADC values and SCr/24h-UPRO, and significant positive correlation was found between cortical ADC and eGFR. There was also a significant negative correlation between medullary ADC values and SCr. Both cortical and medullary ADC values were significantly correlated with histopathological fibrosis score. Conclusion: Renal ADC values strongly correlate with histological measures of fibrosis, and have the potential to enhance the non-invasive monitoring of chronic kidney disease. - Highlights: • Renal ADC values in the CKD patients were lower than those in controls. • Renal ADC values were strongly correlated with histological fibrosis score. • Renal ADC values have the potential to enhance the noninvasive monitoring of CKD

Full Text Available Osteoporosis affects all bones, including those of the facial skeleton. To date the facial bones have not drawn much attention due to the minimal probability of morbid fractures. Hearing and dentition loss due to osteoporosis has been reported. New research findings suggest that radiologic examination of the facial skeleton can be a cost-effective adjunct to complement the early diagnosis and the follow up of osteoporosis patients. Bone-mass preservation treatments have been associated with osteomyelitis of the jawbones, a condition commonly described as osteonecrosis of the jaws (ONJ. The facial skeleton, where alimentary tract mucosa attaches directly to periosteum and teeth which lie in their sockets of alveolar bone, is an area unique for the early detection of osteoporosis but also for the prevention of treatment-associated complications. We review facial bone involvement in patients with osteoporosis and we present data that make the multidisciplinary approach of these patients more appealing for both practitioners and dentists. With regard to ONJ, a tabular summary with currently available evidence is provided to facilitate multidisciplinary practice coordination for the treatment of patients receiving bisphosphonates.

Background: Osteoporosis is considered a major worldwide public health problem. Men and women with osteoporosis are mostly unaware of the illness, until bone fractures occur. It is estimated that more than one in three European women and one in five men over 50 years will experience osteoporotic...... fractures followed by considerable morbidity and mortality. In line with many other chronic illnesses, one of the pronounced challenges related to osteoporosis is considered to be compliance and persistence to medical treatment. The causes of low compliance and persistence to treatment remain unclear....... Living with a chronic illness often affects the entire human life situation, specifically, emotionally and existentially. How this is experienced personally and how this affects the individual’s life is still unknown. Aim: To gain a deeper understanding of patients’ life with osteoporosis by determining...

This study examined the predictive value of serum cystatin C (Cys-C) concentration, measured during routine periodic health examinations, in the renal prognosis of dogs. A cohort of 140 dogs weighing C concentrations were measured during periodic health examinations from December 2013 to March 2016 were prospectively studied, with renal disease-related death the predicted end point. Of the 140 dogs, nine died from renal diseases during the follow-up period (539 ± 249 days). Serum Cys-C concentrations were higher in the dogs that subsequently died of renal disease than in the censored group (0.8 ± 0.25 vs. 0.3 ± 0.1 mg/dl, respectively; P C concentrations (>0.55 mg/dl) had a shorter (P C concentrations (≤0.55 mg/dl). In conclusion, high serum Cys-C concentrations in periodic health examinations in dogs <15 kg predicted poorer prognosis for renal function. Copyright © 2018. Published by Elsevier Ltd.

Odubanjo, M O; Oluwasola, A O; Kadiri, S

2011-09-01

The incidence of CKD (Chronic kidney disease) in Nigeria has been shown by various studies to range between 1.6 and 12.4%. We have shown that the burden of renal disease in Nigeria is probably significantly higher than any previous study on end-stage renal disease (ESRD) has documented, as most studies are hospital-based and fail to include the many patients who do not have access to hospital care. The increased prevalence of ESRD among blacks in the United States and South Africa compared with other races also suggests that ESRD may be more prevalent in Africa than in the United States and other developed nations. Common causes of CKD in Nigerian adults are glomerulonephritis and hypertension, while common causes in children are glomerulonephritis and posterior urethral valves. In the United States, diabetes and hypertension are the commonest causes of CKD and glomerulonephritis plays a less important role. Access to renal replacement therapy (RRT) in Nigeria is limited, and mortality rates are very high, ranging between 40 and 50%. Important steps towards improving the situation are the development of prevention programmes and increased funding to ensure increased availability of RRT. To achieve this, health policies concerning CKD must be formulated, and the lack of a renal registry makes it difficult for this to be done. There is need for the development of a functional organizational structure for the reporting of CKD in Nigeria, the Nigerian Renal Registry.

Full Text Available The oculocerebrorenal syndrome of Lowe, an X-linked multisystem disorder, was diagnosed in a male patient who presented with typical abnormalities of the eyes, kidneys and nervous system. Besides congenital cataracts, renal tubular dysfunction and psychomotor retardation, the patient had also suffered from profound failure to thrive, growth hormone deficiency, severe osteoporosis with hypophosphatemic rickets, and progressive renal dysfunction since early childhood, which were attributed to the metabolic derangements following Fanconi syndrome. Direct sequencing of the OCRL1 gene (responsible for the oculocerebrorenal syndrome of Lowe revealed a de novo c.2282_2283insT in exon 20, which resulted in premature termination of translation (D762X. After monthly intravenous administration of pamidronate since the age of 17.8 years, his urine creatinine clearance and tubular resorption of phosphate increased slightly and bone mineral density was much improved (Z score increased from −7.3 to −3.3 without deterioration of renal function. Simultaneous growth hormone therapy enhanced the positive response. The beneficial osseous and renal effects of the bisphosphonate, along with growth hormone treatment in Lowe syndrome with hypophosphatemia, may be related to reduced renal calcium and phosphate excretion.

Osteoporosis is a systemic skeletal disease characterized by low bone mass and microarchitectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture. Osteoporosis is an enormous public health problem, because it causes multiple fractures in the elderly people, and huge health care cost. The progressive aging of the world's population predicts a substantial increase in the global burden of osteoporosis, so further studying and preventing osteoporosis are often important problems. Since 1986 our department started large investigation of BMDat forearm using single photon absorptiometry (SPA) and in 1991-1993 was undertook Investigation of bone mineral density at the lumbar spine and proximal femur in normal Chinese population using Dual Energy X-ray Absorptiometry(DEXA). The results showed the BMD of all above sites is age-related, the age of peak BMD is different at the forearm, lumbar spine and hip, and the difference is related with sex. After the age of peak bone mass, BMD steadily declined with advancing age. In the Co-ordinated Research Programme on Comparative International Studies of Osteoporosis using Isotope Techniques. The first, we will further study age-, sex-related changes in bone mass among Chinese northern healthy residents in urban. Not only consider that chronic disease and medicine influence on osteoporosis, also consider the influence of life-style factors. The second, the trace elements of tooth and hair samples will be analysed by neutron activation analysis (NAA). It try to find the correlation of trace elements composition between tooth and hair samples. The possible difference in theses elements between osteoporotic patients and controls. (author)

Full Text Available Objective: To evaluate the impact pharmacist-provided screening and education had on patient knowledge of osteoporosis and preventive strategies. Methods: A prospective, randomized, controlled study was conducted at 16 locations of a national supermarket chain pharmacy in the Richmond, Virginia area. Women 30 years and older with no history of osteoporosis were enrolled in the study. Patients self-selected into the study by agreeing to the bone density screening, pharmacist-provided education, and completion of a knowledge survey. Subjects were randomized to complete the osteoporosis-related knowledge survey either before (Group A or after (Group B the screening and education session. The survey was developed after guideline and literature evaluation and was pretested with a group of patients for content and clarity. The survey evaluated knowledge of osteoporosis, risk factors for the disease, appropriate age for testing, and preventive strategies. Groups A and B were compared using t-tests. Results: A total of 110 women were enrolled in the study. The mean (±SD age was 52.5 ± 13.1 years in Group A (n=52 and 52.7 ± 11.5 years in Group B (n=58. Knowledge scores were higher in the group who received pharmacist-provided education prior to completing the survey in each category (knowledge of the disease, risk factors, preventive strategies, and appropriate age for testing and overall (p<0.001.

Osteoporosis is defined as an absolute decrease in the amount of bone to a level below required for mechanical support. It is an important bone disease in elderly people in many countries. Unfortunately, there is no reliable statistical data in Turkey for the incidence of osteoporosis. A decrease in bone mass is the important cause in fractures in osteoporosis. Therefore, we intend to study both bone density and other variables such as trace elements, biomechanical properties and other immunocytochemicals in bone, all combined might give an information about the cause and prevention of osteoporosis.

Renal aging is frequently confused with chronic nephropathy in clinical practice, since there are some similarities between them, particularly regarding reduced glomerular filtration rate (GFR). However, there are many differences between these two entities which can help any practitioner to distinguish between them, such as: GFR deterioration rate, hematocrit, renal handling of urea, creatinine and some electrolytes, tubular acidification, urinalysis, and renal imaging. Differentiation between renal aging and chronic renal disease is crucial in order to avoid unnecessary medicalization of what is a physiological change associated with the healthy aging process, and the potential harmful consequences of such overdiagnosis. A recently described equation (HUGE), as well as an adequate nephrological evaluation and follow up can help physicians to distinguish both entities.

Animal models of osteoporosis - necessity and limitations

Full Text Available There is a great need to further characterise the available animal models for postmenopausal osteoporosis, for the understanding of the pathogenesis of the disease, investigation of new therapies (e.g. selective estrogen receptor modulators (SERMs and evaluation of prosthetic devices in osteoporotic bone. Animal models that have been used in the past include non-human primates, dogs, cats, rodents, rabbits, guinea pigs and minipigs, all of which have advantages and disadvantages. Sheep are a promising model for various reasons: they are docile, easy to handle and house, relatively inexpensive, available in large numbers, spontaneously ovulate, and the sheep's bones are large enough to evaluate orthopaedic implants. Most animal models have used females and osteoporosis in the male has been largely ignored. Recently, interest in development of appropriate prosthetic devices which would stimulate osseointegration into osteoporotic, appendicular, axial and mandibular bone has intensified. Augmentation of osteopenic lumbar vertebrae with bioactive ceramics (vertebroplasty is another area that will require testing in the appropriate animal model. Using experimental animal models for the study of these different facets of osteoporosis minimizes some of the difficulties associated with studying the disease in humans, namely time and behavioral variability among test subjects. New experimental drug therapies and orthopaedic implants can potentially be tested on large numbers of animals subjected to a level of experimental control impossible in human clinical research.

Chronic kidney disease in children is an irreversible process that may lead to end-stage renal disease. The mortality rate in children with end-stage renal disease who receive dialysis increased dramatically in the last decade, and it is significantly higher compared with the general pediatric population. Furthermore, dialysis and transplant patients, who have developed end-stage renal disease during childhood, live respectively far less as compared with age/race-matched populations. Different reports show that cardiovascular disease is the leading cause of death in children with end-stage renal disease and in adults with childhood-onset chronic kidney disease, and that children with chronic kidney disease are in the highest risk group for the development of cardiovascular disease. Urea, which is generated in the liver during catabolism of amino acids and other nitrogenous metabolites, is normally excreted into the urine by the kidneys as rapidly as it is produced. When renal function is impaired, increasing concentrations of blood urea will steadily accumulate. For a long time, urea has been considered to have negligible toxicity. However, the finding that plasma urea is the only significant predictor of aortic plaque area fraction in an animal model of chronic renal failure -accelerated atherosclerosis, suggests that the high levels of urea found in chronic dialysis patients might play an important role in accelerated atherosclerosis in this group of patients. The aim of this review was to provide novel insights into the role played by urea in the pathogenesis of accelerated cardiovascular disease in renal failure.

Type I glycogen storage disease (GSD-I) is an inherited disorder affecting glycogenolysis and gluconeogenesis. The characteristic manifestations are hepatomegaly, hypoglycemia, hyperlacticacidemia, hyperuricemia, and hyperlipidemia. Renal disease is regarded as a long-term complication and is reported mainly in older patients. We report the renal manifestations and renal ultrasonographic findings of GSD-I in infancy and early childhood in order to assess the role of renal sonography in the diagnosis of GSD-I. We retrospectively reviewed our hospital's database for patients with GSD-I from January 1993 to September 2004. The records of five patients were reviewed for this study. These five patients were diagnosed when they were younger than 3 years old. Data extracted from the charts included the initial extrarenal and renal manifestations, laboratory data, and imaging studies. We analyzed the indications for, and results of, renal sonography. In addition to the clinical presentations and laboratory abnormalities, all five children had nephromegaly and increased echogenicity on ultrasonography on their first visit, although only a minor degree of tubular dysfunction was noted clinically. Three of these five patients had nephrocalcinosis or renal stones or both. Hyperechoic large kidneys, nephrocalcinosis, and renal stones are common in GSD-I. They can be present in early infancy. Abnormalities on renal sonography might suggest GSD-I in a patient with suspected inborn errors of metabolism. (orig.)

Renal perfusion in chronic liver diseases: Evaluation by radiotechnetium renography

Twenty-four patients with chronic liver diseases and seven normal controls were studied using renal and hepatic radiotechnetium angiography. The time-activity histograms generated were employed to calculate both the renal perfusion index (RPI) and the hepatic perfusion index (HPI). Renal perfusion proved to be reduced not only in cirrhotic patients but also in patients with aggressive chronic hepatitis, as well as in those with persistent chronic hepatitis. The HPI, which is to be considered as being strictly dependent on portal flow, only fell significantly in the group of cirrhotic patients. In all patient groups, the correlation coefficient between the HPI and RPI (mean of the two kidneys) was low (r=0.275) and not significant (P>0.05). After Warren's splenorenal derivation, renal perfusion did not improve but worsened, particularly in the left kidney where derivation anastomosis probably caused a venous overload. (orig.)

Live imaging of osteoclast inhibition by bisphosphonates in a medaka osteoporosis model

Directory of Open Access Journals (Sweden)

Tingsheng Yu

2016-02-01

Full Text Available Osteoclasts are bone-resorbing cells derived from the monocyte/macrophage lineage. Excess osteoclast activity leads to reduced bone mineral density, a hallmark of diseases such as osteoporosis. Processes that regulate osteoclast activity are therefore targeted in current osteoporosis therapies. To identify and characterize drugs for treatment of bone diseases, suitable in vivo models are needed to complement cell-culture assays. We have previously reported transgenic medaka lines expressing the osteoclast-inducing factor receptor activator of nuclear factor κB ligand (Rankl under control of a heat shock-inducible promoter. Forced Rankl expression resulted in ectopic osteoclast formation, as visualized by live imaging in fluorescent reporter lines. This led to increased bone resorption and a dramatic reduction of mineralized matrix similar to the situation in humans with osteoporosis. In an attempt to establish the medaka as an in vivo model for osteoporosis drug screening, we treated Rankl-expressing larvae with etidronate and alendronate, two bisphosphonates commonly used in human osteoporosis therapy. Using live imaging, we observed an efficient, dose-dependent inhibition of osteoclast activity, which resulted in the maintenance of bone integrity despite an excess of osteoclast formation. Strikingly, we also found that bone recovery was efficiently promoted after inhibition of osteoclast activity and that osteoblast distribution was altered, suggesting effects on osteoblast-osteoclast coupling. Our data show that transgenic medaka lines are suitable in vivo models for the characterization of antiresorptive or bone-anabolic compounds by live imaging and for screening of novel osteoporosis drugs.

Renal Impairment with Sublethal Tubular Cell Injury in a Chronic Liver Disease Mouse Model.

Directory of Open Access Journals (Sweden)

Tokiko Ishida

Full Text Available The pathogenesis of renal impairment in chronic liver diseases (CLDs has been primarily studied in the advanced stages of hepatic injury. Meanwhile, the pathology of renal impairment in the early phase of CLDs is poorly understood, and animal models to elucidate its mechanisms are needed. Thus, we investigated whether an existing mouse model of CLD induced by 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC shows renal impairment in the early phase. Renal injury markers, renal histology (including immunohistochemistry for tubular injury markers and transmission electron microscopy, autophagy, and oxidative stress were studied longitudinally in DDC- and standard diet-fed BALB/c mice. Slight but significant renal dysfunction was evident in DDC-fed mice from the early phase. Meanwhile, histological examinations of the kidneys with routine light microscopy did not show definitive morphological findings, and electron microscopic analyses were required to detect limited injuries such as loss of brush border microvilli and mitochondrial deformities. Limited injuries have been recently designated as sublethal tubular cell injury. As humans with renal impairment, either with or without CLD, often show almost normal tubules, sublethal injury has been of particular interest. In this study, the injuries were associated with mitochondrial aberrations and oxidative stress, a possible mechanism for sublethal injury. Intriguingly, two defense mechanisms were associated with this injury that prevent it from progressing to apparent cell death: autophagy and single-cell extrusion with regeneration. Furthermore, the renal impairment of this model progressed to chronic kidney disease with interstitial fibrosis after long-term DDC feeding. These findings indicated that DDC induces renal impairment with sublethal tubular cell injury from the early phase, leading to chronic kidney disease. Importantly, this CLD mouse model could be useful for studying the

An osteoporotic condition of young lambs which has occurred regularly for many years in an old lead mining area in Southern Scotland is described. The principal feature of the disease is an excessive fragility of the bones due to osteoporosis. This is responsible for a variety of locomotor disturbances ranging from a stiff gait to complete posterior paralysis. The lead content of the soil and pasture and the blood, liver, kidneys and bones was unusually high. Unusually high values were also obtained for the zinc content of the blood and tissues of affected lambs. The possible involvement of these elements and chelating metabolites in the etiology of the disease is discussed. 59 references, 4 tables.

The Latin American Dialysis and Renal Transplant Registry (RLADTR) was founded in 1991; it collects data from 20 countries which are members of Sociedad Latinoamericana de Nefrología e Hipertension. This paper presents the results corresponding to the year 2010. This study is an annual survey requesting data on incident and prevalent patients undergoing renal replacement treatment (RRT) in all modalities: hemodialysis (HD), peritoneal dialysis (PD) and living with a functioning graft (LFG), etc. Prevalence and incidence were compared with previous years. The type of renal replacement therapy was analyzed, with special emphasis on PD and transplant (Tx). These variables were correlated with the gross national income (GNI) and the life expectancy at birth. Twenty countries participed in the surveys, covering 99% of the Latin American. The prevalence of end stage renal disease (ESRD) under RRT in Latin America (LA) increased from 119 patients per million population (pmp) in 1991 to 660 pmp in 2010 (HD 413 pmp, PD 135 pmp and LFG 111 pmp). HD proportionally increased more than PD, and Tx HD continues to be the treatment of choice in the region (75%). The kidney Tx rate increased from 3.7 pmp in 1987 to 6.9 pmp in 1991 and to 19.1 in 2010. The total number of Tx's in 2010 was 10 397, with 58% deceased donors. The total RRT prevalence correlated positively with GNI (r2 0.86; P < 0.05) and life expectancy at birth (r2 0.58; P < 0.05). The HD prevalence and the kidney Tx rate correlated significantly with the same indexes, whereas the PD rate showed no correlation with these variables. A tendency to rate stabilization/little growth was reported in the most regional countries. As in previous reports, the global incidence rate correlated significantly only with GNI (r2 0.63; P < 0.05). Diabetes remained the leading cause of ESRD. The most frequent causes of death were cardiovascular (45%) and infections (22%). Neoplasms accounted for 10% of the causes of death. The

THE COMPARATIVE ANALYSIS OF RENAL FUNCTION IN LIVER DISEASES USING COCKCROFT-GAULT FORMULAE AND CREATININE CLEARANCE

Full Text Available BACKGROUND Kidney dysfunction in liver disease can be due to different aetiologies and can have diverse manifestations. Most of the abnormalities of kidney function in cirrhosis are of functional origin namely, sodium retention, impaired free water excretion and renal vasoconstriction with decrease in renal perfusion and glomerular filtration rate. Renal dysfunction in chronic liver disease usually follows a progressive course- the final phase being Hepatorenal Syndrome (HRS. MATERIALS AND METHODS This study included patients with chronic liver disease being treated as inpatients in the Department of General Medicine, Konaseema Institute of Medical Sciences, Amalapuram. Evidence for chronic liver disease being defined by a compatible clinical profile (signs of liver cell failure or reduced liver span along with biochemical (altered liver function tests, reversal of albuminglobulin ratio or sonographic evidence (altered echotexture of liver or tissue diagnosis (positive liver biopsy for cirrhosis. RESULTS Eighteen percent, i.e. 5 out of the 28 patients with creatinine clearance more than 60 mL/minute by Cockcroft-Gault formula were found to have creatinine clearance values less than 40 mL/minute when done by timed urine collection P value calculated was found to be less than 0.0001, which is statistically significant. CONCLUSION In chronic liver disease, serum creatinine alone is not a reliable marker to assess renal dysfunction. Calculating creatinine clearance by using Cockcroft-Gault formula overestimates renal function in cirrhotics. Creatinine clearance measured by timed urine collections should be done routinely to assess renal reserve in advanced liver disease. Alcoholism appears to have adverse effect on renal function when compared with other aetiologies of cirrhosis.

Osteoporosis and Somatization of Anxiety

2013-12-01

Full Text Available Chronic stress can now be physiologically traced as a significant player in the creation of osteoporotic bones. The present pilot study involved 100 women (N = 42 have been diagnosed with osteopenia, N = 21 have been diagnosed with osteoporosis, N = 37 had a non-osteoporotic condition who participated in the Hellenic Society of Osteoporosis Association Support. Correlations between somatic symptoms of anxiety and osteoporosis, and among medications and somatization in women were explored. Assessments were based on a self-report demographic questionnaire and on the Short Anxiety Screening Test (SAST administered for detection of anxiety disorder and somatization. Statistical analysis detected non-significant differences regarding the correlation between anxiety symptomatology or somatization due to osteoporosis and osteopenia diagnosis. The same pattern is observed among women’s age group, the occupational and marital status. Hypothesis that the osteoporosis and osteopenia group would manifest significant relationships with the age group and medicines was confirmed, as well as between somatization and medicines that women with osteoporosis and osteopenia undertake. The results suggest that women are not prone to manifest anxiety or somatization in relation to the osteoporosis condition. However, the majority of women with osteoporosis and osteopenia consume more than two medicines other than those for osteoporosis. This quantity and combination they undertake appear to contribute and deteriorate their anxiety/somatization symptomatology. Further research based on a larger sample would give more definite results.

To evaluate change of serum beta{sub 2}-microglobulin concentration (sbeta{sub 2}-MG) and the usefulness of sbeta{sub 2}-MG and sbeta{sub 2}-MG/serum creatinine concentration (sCr) ratio in various renal diseases, sbeta{sub 2}-MG and sCr were measured in 25 normal controls and 90 patients of various renal diseases (16 cases of glomerulonephritis, 12 cases of acute renal failure, 8 cases of chronic renal failure, 24 cases of nephrotic syndrome, 15 cases of tubulointerstitial diseases and 15 cases of lupus nephritis) using Phadebas beta{sub 2}-Micro Test kits. The results were as follows; 1) In normal control, the mean value of sbeta{sub 2}-MG was 1.65+-0.41 mg/l and the mean value of sbeta{sub 2}-MG/sCr ratio was 0.14+-0.05. 2) In various renal diseases, the mean value of sbeta{sub 2}-MG was 6.74+-5.47 mg/l. The mean value of sbeta{sub 2}-MG/sCr ratio was 0.24+-0.11 and significantly elevated than that of normal contro1. (P<0.05). 3) The correlation between sbeta-2-MG and sCr in glomerular and tubulointerstitial disease was log sbeta{sub 2}-MG=0.90 log sCr-0.48 and its correlation coefficient was 0.78 (P<0.05). 4) In glomerular disease, the correlation between sbeta{sub 2}-MG and sCr was log sbeta{sub 2}-MG=0.89 log sCr-0.46 (r-0.76) and in tubulointerstitial disease, it was log sbeta{sub 2}-MG=0.95 1og sCr-0.59 (r-0.87). There was no significant difference between the two groups (p<0.05). 5) Among 32 cases of glomerular and tubulointerstitial disease patients, whose sCr was within normal range, 17 cases showed elevated sbeta{sub 2}-MG. The mean values of sbeta{sub 2}-MG/sCr ratio in these patients was 0.30+-0.14 and significantly elevated than that of normal control (p<0.05). 6) In 15 cases of lupus nephritis, 12 cases showed elevated sbeta{sub 2}-MG with normal sCr and 12 cases showed elevated sbeta{sub 2}-MG/sCr ratio. With above results, It was found that the sbeta{sub 2}-MG can be used as an index of glomerular filtration rate as in the case of sCr and thats

Background: Coronary heart disease patients and end-stage renal disease patients have been documented to have an increased amount of coronary artery calcifications (CAC). Purpose: To evaluate the distribution of CAC and its influence on interscan variability of measurement in end-stage renal disease and coronary heart disease patients, proven to have calcifications. Material and Methods: 69 patients having CAC, including 34 with coronary heart disease and 35 with end-stage renal disease, were scanned twice with multidetector-row computed tomography (MDCT). Amount of CAC was determined as the number of calcified lesions (CN), total calcium score (CS), calcium volume (CV), and calcium mass (CM). Distribution of CAC was evaluated on a per-patient basis as the median CS and CM of a single lesion. Density of the calcifications was calculated as the patient's CM divided by CV. Results: The overall median CS was 457.2, and the median CM was 75.6 mg. There were no significant differences in the number of calcified lesions, CS, or CM between the two groups. Both CS and CM of a single lesion, as well as the mean calcium density were lower in renal disease patients (P<0.05) than in coronary heart disease subjects. The relative interscan variability of coronary calcium measurement was higher in the renal disease group (P<0.05). There was a negative correlation between the calcium concentration and the relative interscan variability. Conclusion: The results indicate that the coronary calcium distribution influences the measurement interscan reproducibility, and the distribution may differ between end-stage renal disease patients and coronary heart disease patients, reflecting the dissimilar nature of coronary calcifications in those groups

Full Text Available Background: Osteoporosis is a silent metabolic disease characterized by diminished bone mass and change in bone microstructure which cause increment of fracture risk. Until now, osteoporosis still becomes one of major health problems around the world. In Indonesia, the incidence of osteoporosisis 25%. Previous study have shown the relation between osteoporosis and IL-6 gene polymorphism at-572G>C and -174 G>C. There are some controversies about the correlation between thesepolymorphism and osteoporosis because of different result between each study. Genotype G polymorphism at -572 G>C of IL-6 gene has been correlated with lower Bone mineral density (BMD and Genotype G polymorphism at -174G>C of IL-6 gene has been correlated with higher BMD value.In Indonesia, there are still no study about the association between IL-6 gene polymorphism and osteoporosis. In the future this IL-6 gene polymorphism could be used as a genetic marker for osteoporosis in postmenopausal woman. The objective of this study is to determine the difference ofgenotype of -572G>C and -174G>C polymorphism of IL-6 gene and osteoporosis in Balinese postmenopausal women.Method: This research design is a case control study.

Viscosity, an important determinant of microcirculatory hemodynamics, is related to hematocrit (HCT), and may be altered by renal failure or its treatment. To assess these factors, we studied the effect of dialysis on the viscosity of whole blood, plasma, and reconstituted 70% HCT blood of eight continuous ambulatory peritoneal dialysis (CAPD) and nine hemodialysis (HD) patients under steady shear flow conditions at different shear rates, before and after dialysis, compared with nine normal subjects. The density of the red blood cells (RBCs), a marker of cell hydration, was measured in HD patients by a nonaqueous differential floatation technique. Whole blood viscosity was higher in controls than patients, and correlated with HCT before treatment (P less than 0.05) at shear rates of 11.5 to 230 s-1) in HD patients, and 23 to 230 s-1 in all end-stage renal disease (ESRD) patients. In contrast, whole blood viscosity correlated with HCT in CAPD patients only at the lowest shear rates (2.3 and 5.75 s-1, P less than 0.05). Plasma viscosity was higher in CAPD patients than both HD patients before treatment and controls (P less than 0.05, analysis of variance [ANOVA]), despite lower plasma total protein, albumin, and similar fibrinogen concentration compared with HD patients. When all samples were reconstituted to 70% HCT, CAPD patients had higher whole blood viscosity than control subjects'. The high HCT blood viscosity of the ESRD patients was higher than control subjects' at capillary shear rates, suggesting increased RBC aggregation and decreased RBC deformability in patients with renal disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Full Text Available Osteoporosis was one of degenerative disease that is common in the elderly. There was a several of risk factors of osteoporosis. Two of them were physical activity and smoking habits. Attitude was one part of a person’s behavior that may affect the prevention of disease. This study aimed to analyze the affect of physical activity, smoking habits, and attitude of the elderly to incidence of osteoporosis. This study is an observational study with case control design. The number of samples in this study was 66 elderly who visited Osteoporosis Clinic Husada Utama Hospital in Surabaya. Respondent selection taken with systematic random sampling. The independent variables of this study were physical activity, smoking habit, and attitude, while the dependent variable was incidence of osteoporosis. Based on correlation analysis with logistic regression test showed there was a significant correlation (p<0,05 between physical activity, smoking habits, and attitude. Odds Ratio (OR in this study for physical activity was 14,764 ,smoking habit was 9,646 and attitude was 5,623. The conclusion of this study, there was physical activity as a dominant affect after controlled smoking habits and attitude to incidence of osteoporosis. The suggestion is to do physical activity three times a week, consume healthy food and beverage, take an enough sleep,reduce stress factors and stop smoking also.   Keywords: Physical activity, smoking habits, elderly

A 16 year old boy with Noonan syndrome diagnosed in the 3rd month of life was treated for renal insufficiency and hepatic tumor. Hemodialisis was started in preparation for surgery. Exacerbation of renal insufficiency occurred after surgical removal of the hepatic tumor together with the right hepatic lobe. Histopathologic examination showed adenoma hepatocellulare. Cysts in the extraperitoneal space appeared in the following months and were identified as cystes dysontogenetici benigni ''hamartia''. Renal function deteriorated during this time to end stage renal disease. The authors emphasize the possibility of good mental development in a patients with Noonan syndrome as well as the presence of urinary tract abnormalities and renal insufficiency of unknown origin - a phenomenon that has not yet been reported in other cases of Noonan syndrome.

El objetivo de este trabajo es revisar nuestra experiencia en el diagnóstico y tratamiento de estas afecciones. Entre 1984 y 2004 consultaron seis puérperas por osteoporosis y dos por osteoporosis regional. En el primer grupo tres pacientes refirieron fracturas vertebrales y las restantes grave desmineralización detectada por densitometría ósea (DEXA. Los síntomas comenzaron en el tercer trimestre o en el posparto inmediato. Cinco eran primíparas mientras que una era multípara y había amamantado por un tiempo prolongado. Los factores de riesgo detectados fueron: baja ingesta láctea, delgadez, osteoporosis familiar, amenorreas, tabaquismo y corticoterapia. El laboratorio mostró recambio óseo acelerado. La DEXA documentó marcada desmineralización especialmente en esqueleto axial. En todas se interrumpió la lactancia y se indicaron drogas anti-resortivas en cuatro, estrógenos en una y sólo calcio y vitamina D en otra. Todas, menos una, evolucionaron favorablemente independientemente del tratamiento utilizado. Dos pacientes consultaron por dolor y limitación funcional progresiva durante el embarazo, en cadera izquierda y pie derecho respectivamente. La DEXA mostró desmineralización del lado afectado.

Full Text Available Osteoporosis is now considered as one of the major and growing health care problems around the world. Osteoporosis is the most prevalent metabolic bone disease among developed countries and it is defined as a systemic skeletal disease characterized by low bone mass and microarchitectural deterioration of bone tissue with a consequent increase in bone fragility. Bone is a highly metabolically active tissue in which the processes of osteoblastic bone formation and osteoclastic bone resorption are continuous throughout life. Coupling of osteoblast and osteoclast action ensures that a normal bone structure is maintained. A loss of bone homeostasis may result in a decrease in bone mass leading to osteoporosis or in a defect in the mineralization of bone. Numerous genetic, hormonal, nutritional and life-style factors contribute to the acquisition and maintenance of bone mass. Among them, genetic variations explain as much as 50-80% of the variance for bone mineral density (BMD in the population. Many genes that could be related to osteoporosis have been studied and of them all Vitamin D receptor (VDR, estrogen receptor alpha (ESRα and collagen 1 alpha 1 chain (COL1A1 genes have been the most focused on.

Además, la litiasis renal puede ser expresión también de enfermedades extrarrenales, entre las cuales destaca riesgo aumentado de osteoporosis. Estudios nacionales muestran que las causas de litiasis renal en Chile son similares a las comunicadas internacionalmente, destacando la hipercalciuria idiopática como el principal factor de riesgo. A pesar de los avances en técnicas urológicas de remoción de cálculo, éstas no modifican la historia natural de la litiasis renal. Así, en los pacientes sin tratamiento médico, la recurrencia es la regla más que la excepción. En esta revisión se actualiza el estudio y manejo endocrinológico de la litiasis renal, para el cual la evidencia muestra que éste es eficaz y seguro en la prevención de recurrencia de litiasis renal y control de enfermedades asociadas, complementando así el manejo urológico de esta importante enfermedad.

Highlight: • We first report that anti-osteopontin mAb could protect osteoporosis in mice. • Anti-osteopontin mAb could promote the osteoclast apoptosis. • Targeting osteopontin might have therapeutic potentials for osteoporosis. - Abstract: Osteopontin (OPN) is abundant in mineralized tissues and has long been implicated in bone remodeling. However, the therapeutic effect of targeting OPN in bone loss diseases and the underlying molecular mechanism remain largely unknown. Here, we reported that anti-OPN mAb (23C3) could protect against ovariectomy-induced osteoporosis in mice, demonstrated by microcomputed tomography analysis and histopathology evaluation. In vitro assay showed that 23C3 mAb reduced osteoclasts (OCs)-mediated bone resorption through promotion of mature OC apoptosis. Thus, the study has important implications for understanding the role of OPN in OC bone resorption and survival, and OPN antagonists may have therapeutic potential for osteoporosis and other osteopenic diseases.

Pretransplant renal failure is commonly reported to be a poor prognostic indicator affecting survival after liver transplantation (LT). However, whether the impact of renal failure on patient outcome varies according to the aetiology of the underlying liver disease is largely unknown. We investigated the association between renal failure at the time of LT and patient outcome in patients with alcoholic liver disease (ALD) (n = 6920), non-alcoholic steatohepatitis (NASH) (n = 2956) and hepatitis C (HCV) (n = 14 922) using the United Network for Organ Sharing (UNOS) database between February 2002 and December 2013. A total of 24 798 transplant recipients were included. The presence of renal failure was more frequently seen in patients with ALD (23.95%) and NASH (23.27%) compared to patients with HCV (19.38%) (P renal failure was an independent predictor of poor survival. Renal failure showed detrimental effect on patient survival in the overall series (HR = 1.466, P renal failure was less marked in patients with ALD (HR = 1.31, P renal failure had better long-term prognosis than non-ALD patients. Renal failure at the time of LT conferred a lower patient and graft survival post-LT. However, renal failure has less impact on the outcome of patients with ALD than that of patients with non-alcoholic liver disease after LT. © 2016 John Wiley & Sons A/S.

As the population ages, diseases of the elderly are becoming more common, including osteoporosis. Ways to assess the risk of fracture and the distribution and effects of known risk factors for osteoporosis will be important in planning for future healthcare needs, as well as in the development of preventive strategies. The study population included 6029 men and women aged 20-90 who underwent examination in the second follow-up wave of the Study of Health in Pomerania (SHIP-2) or in the basal SHIP-Trend Study. The risk of fracture was estimated on the basis of quantitative ultrasonography of the calcaneus. Prior fractures and risk factors for osteoporosis were ascertained in standardized interviews. 4.6% of the male subjects and 10.6% of the female subjects were judged to have an elevated risk of fracture. The corresponding percentages among subjects over age 65 were 8.8% for men and 28.2% for women. Even among subjects under age 55, risk factors for osteoporosis were associated with lower bone stiffness: the mean stiffness index was 103/98 (men/women) without risk factors, 99/96 with one risk factor, and 93/95 with more than one risk factor. Logistic regression analysis yielded an odds ratio of 1.89 (95% confidence interval: 1.44-2.50; p<0.01) for prevalent fractures among subjects aged 75 and older compared to subjects under age 55. The data indicate a high prevalence of osteoporosis from age 65 onward. These findings are consistent with those of other studies from Germany and across Europe. Younger men and women should already begin taking steps to counteract modifiable risk factors.

Osteonecroses in children with chronical renal diseases before and after kidney transplantation

From 1969 to 1980 202 children suffering from chronic renal insufficiency underwent treatment in the Children's Hospital of Heidelberg University. In 36 patients kidney transplantations were performed. Two children developed femoral head necroses before transplantation without corticosteroid therapy. Three patients developed femoral head necroses in one or both sides within one to 24 months after kidney transplantation. All children with femoral head necrosis were suffering from congenital renal disease and had a history of servere renal osteodystrophy which was followed by severe coxa vara. Coxa vara and the resulting faulty loading seem to be essential factors for the development of femoral head necrosis in patients with renal insufficiency before and after kidney transplantation.

Perretta, Fernando; Antongiovanni, Norberto; Jaurretche, Sebastián

2017-01-01

Fabry disease is an X-linked lysosomal storage disorder resulting from the deficiency or absence of the enzyme alpha galactosidase A; this defect leads to the systemic accumulation of globotriaosylceramide and its metabolites. Organic involvement in men is well known, but in women it is controversial, mainly due to the random X-chromosome inactivation in each of their cells (Lyon hypothesis). This would explain why women (heterozygotes) present a wide variability in the severity of their phenotype. The manifestations are multisystemic and begin in early childhood, reaching a severe compromise in adulthood. Typical acroparesthesia in hands and feet, gastrointestinal symptoms, angiokeratomas, dyshidrosis, hearing loss, arrhythmias, hypertrophic cardiomyopathy, cerebrovascular accidents, and renal failure can be observed. Nephropathy is one of the major complications of Fabry disease. Glomerular and vascular changes are present before progression to overt proteinuria and decreased glomerular filtration rate, even in pediatric patients. A case of incipient renal involvement in a girl with classic Fabry disease is reported.

Lachlan B. McMillan

2017-11-01

Full Text Available Osteoporosis is an age-related disease, characterised by low bone mineral density (BMD and compromised bone geometry and microarchitecture, leading to reduced bone strength. Physical activity (PA has potential as a therapy for osteoporosis, yet different modalities of PA have varying influences on bone health. This review explores current evidence for the benefits of PA, and targeted exercise regimes for the prevention and treatment of osteoporosis in older adults. In particular, the outcomes of interventions involving resistance training, low- and high-impact weight bearing activities, and whole-body vibration therapy are discussed. Finally, we present recommendations for future research that may maximise the potential of exercise in primary and secondary prevention of osteoporosis in the ageing population.

Osteoporosis, Fractures, and Diabetes

Directory of Open Access Journals (Sweden)

Peter Jackuliak

2014-01-01

Full Text Available It is well established that osteoporosis and diabetes are prevalent diseases with significant associated morbidity and mortality. Patients with diabetes mellitus have an increased risk of bone fractures. In type 1 diabetes, the risk is increased by ∼6 times and is due to low bone mass. Despite increased bone mineral density (BMD, in patients with type 2 diabetes the risk is increased (which is about twice the risk in the general population due to the inferior quality of bone. Bone fragility in type 2 diabetes, which is not reflected by bone mineral density, depends on bone quality deterioration rather than bone mass reduction. Thus, surrogate markers and examination methods are needed to replace the insensitivity of BMD in assessing fracture risks of T2DM patients. One of these methods can be trabecular bone score. The aim of the paper is to present the present state of scientific knowledge about the osteoporosis risk in diabetic patient. The review also discusses the possibility of problematic using the study conclusions in real clinical practice.

Full Text Available Osteoporosis is a metabolic bone disease, and is characterized by low bone mass and microstructure deterioration of the bone, which leads to increased risk of fracture. Biomarker of bone metabolism can be seen as beginning of bone loss and first detection before imbalanced bone turnover comes. Biomarker of bone formation as serum bone alkaline fosfatase, osteocalcin (OC, procollagen type I, and biomarker of bone resorption as urine pyridinoline (Pyd and deoxypyridinoline (Dpd crosslinks, hydroxyprolin. The simultaneous examination of serum OC and urine Pyd or Dpd as a very good screening test for determination of bone imbalanced at the moment of the menopausal or the beginning of the pasca menopausal. Saliva as a potential diagnostic fluid for the assessment of osteoporosis biomarker concentrations. The study found elevated three classic warning signs for osteopororsis os OC, Dpd and 116 in the saliva of sheep without ovaries, which were similar to the levels of signs found in their blood and urine. Expectations, that the test may become available within five years and one day the test may be able to be performed at home like pregnancy test. Osteoporosis biomarker in saliva suggested detected of bone mass density easier. Beside that can be used as a method of early diagnostic and as a monitor therapy that as salinity of the examinations of bone mass on radiology.

Biophysical properties of normal and diseased renal glomeruli.

The mechanical properties of tissues and cells including renal glomeruli are important determinants of their differentiated state, function, and responses to injury but are not well characterized or understood. Understanding glomerular mechanics is important for understanding renal diseases attributable to abnormal expression or assembly of structural proteins and abnormal hemodynamics. We use atomic force microscopy (AFM) and a new technique, capillary micromechanics, to measure the elastic properties of rat glomeruli. The Young's modulus of glomeruli was 2,500 Pa, and it was reduced to 1,100 Pa by cytochalasin and latunculin, and to 1,400 Pa by blebbistatin. Cytochalasin or latrunculin reduced the F/G actin ratios of glomeruli but did not disrupt their architecture. To assess glomerular biomechanics in disease, we measured the Young's moduli of glomeruli from two mouse models of primary glomerular disease, Col4a3(-/-) mice (Alport model) and Tg26(HIV/nl) mice (HIV-associated nephropathy model), at stages where glomerular injury was minimal by histopathology. Col4a3(-/-) mice express abnormal glomerular basement membrane proteins, and Tg26(HIV/nl) mouse podocytes have multiple abnormalities in morphology, adhesion, and cytoskeletal structure. In both models, the Young's modulus of the glomeruli was reduced by 30%. We find that glomeruli have specific and quantifiable biomechanical properties that are dependent on the state of the actin cytoskeleton and nonmuscle myosins. These properties may be altered early in disease and represent an important early component of disease. This increased deformability of glomeruli could directly contribute to disease by permitting increased distension with hemodynamic force or represent a mechanically inhospitable environment for glomerular cells.

Chronic kidney disease in children is an irreversible process that may lead to end-stage renal disease. The mortality rate in children with end-stage renal disease who receive dialysis increased dramatically in the last decade, and it is significantly higher compared with the general pediatric population. Furthermore, dialysis and transplant patients, who have developed end-stage renal disease during childhood, live respectively far less as compared with age/race-matched populations. Different reports show that cardiovascular disease is the leading cause of death in children with end-stage renal disease and in adults with childhood-onset chronic kidney disease, and that children with chronic kidney disease are in the highest risk group for the development of cardiovascular disease. Urea, which is generated in the liver during catabolism of amino acids and other nitrogenous metabolites, is normally excreted into the urine by the kidneys as rapidly as it is produced. When renal function is impaired, increasing concentrations of blood urea will steadily accumulate. For a long time, urea has been considered to have negligible toxicity. However, the finding that plasma urea is the only significant predictor of aortic plaque area fraction in an animal model of chronic renal failure -accelerated atherosclerosis, suggests that the high levels of urea found in chronic dialysis patients might play an important role in accelerated atherosclerosis in this group of patients. The aim of this review was to provide novel insights into the role played by urea in the pathogenesis of accelerated cardiovascular disease in renal failure. PMID:29483797

Full Text Available Introduction: Diabetes Mellitus (DM is a common chronic disease accompanied by severe complications. It is the leading cause of End-Stage Renal Disease (ESRD requiring management either by haemodialysis (HD or peritoneal dialysis (PD. The chronicity of the disease, and its complications, affects the psychological, family and social life of the patients and their Quality of Life (QoL. Aim: of the present study was to estimate the disease burden of patients with diabetic nephropathy (DN during pre-ESRD and during End-Stage Renal Disease. Methods: A sample of 103 patients with DN treated at the General Hospital of Veria were studied during May and June 2016. The study was conducted using the Dialysis Symptoms Index (DSI for the assessment of Chronic Kidney Disease (CKD symptom load and the European Quality of Life (EuroQol questionnaire for assessing the QoL of patients in the Renal Outpatient Clinic, Haemodialysis and Peritoneal Dialysis Unit. Results: It was found that the Renal Replacement Method (HD or PD, the presence of DM and CKD’s stage affect significantly the patients’ self-assessment regarding painful symptoms of DN. Furthermore, the above factors have major impact on some aspects of patients’ QoL, such as mobility and self-care. Conclusions: Pre-End Stage patients experience more severe painful symptoms of DN compared to patients on Renal Replacement Therapies.

Full Text Available Among many complications of sickle cell disease, renal failure is the main contributor to early mortality. It is present in up to 21% of patients with sickle cell disease. Although screening for microalbuminuria and proteinuria is the current acceptable practice to detect and follow renal damage in patients with sickle cell disease, there is a crucial need for other, more sensitive biomarkers. This becomes especially true knowing that those biomarkers start to appear only after more than 60% of the kidney function is lost. The primary purpose of this study is to determine whether lactate dehydrogenase (LDH correlates with other, direct and indirect bio-markers of renal insufficiency in patients with sickle cell disease and, therefore, could be used as a biomarker for early renal damage in patients with sickle cell disease. Fifty-five patients with an established diagnosis of sickle cell disease were recruited to in the study. Blood samples were taken and 24-h urine collection samples were collected. Using Statcrunch, a data analysis tool available on the web, we studied the correlation between LDH and other biomarkers of kidney function as well as the distribution and relationship between the variables. Regression analysis showed a significant negative correlation between serum LDH and creatinine clearance, R (correlation coefficient = -0.44, P = 0.0008. This correlation was more significant at younger age. This study shows that in sickle cell patients LDH correlates with creatinine clearance and, therefore, LDH could serve as a biomarker to predict renal insufficiency in those patients.

Objective Vitamin K2 (menatetrenone) is an effective treatment for patients with postmenopausal osteoporosis. We herein performed a subanalysis of patients with systemic autoimmune diseases undergoing glucocorticoid therapy in our previous prospective study. Methods Sixty patients were categorized into a group with vitamin K2 treatment (n=20, Group A) and a group without vitamin K2 treatment (n=40, Group B). All patients were treated with bisphosphonates. Results Serum levels of osteocalcin and undercarboxylated osteocalcin decreased significantly after the start of glucocorticoid therapy in both groups, while the serum osteocalcin level was significantly higher in Group A than Group B during the third (p=0.0250) and fourth weeks (p=0.0155). The serum level of the N-terminal peptide of type I procollagen, a bone formation marker, decreased during glucocorticoid therapy, but was significantly higher in Group A than Group B during the fourth week (p=0.0400). The bone mineral density and fracture rate showed no significant differences between the two groups. Conclusion Although vitamin K2 improves bone turnover markers in patients with osteoporosis on glucocorticoid therapy, it has no significant effect on the bone mineral density and fracture rate after 1.5 years of treatment.

Pregnancy and lactation-associated osteoporosis (PLO) is a rare form of osteoporosis, which occurs in the last trimester or postpartum. So far 100 cases have been published. The leading symptoms are severe low back pain or less frequently hip pain. Many patients develop postpartum depression due to inability to care for the baby and vertebral fractures. The therapeutic decision has to be made individually but teriparatid and bisphosphonates seem to be the best option. We report the clinical course (16 years) of a 37-year-old patient with PLO, who suffered 6 vertebral fractures. There were severe physical limitations and mental problems caused by the disease. The patient was treated by multimodal therapy including physiotherapy and psychotherapy and bisphosphonates were given. The time between the onset of symptoms and diagnosis was 5 months. No further fractures occurred in the following 16 years. The physical and mental condition significantly improved.

2016-11-01

OBJECTIVE Pedicle screw instrumentation of the osteoporotic spine carries an increased risk of screw loosening, pullout, and fixation failure. A variety of techniques have been used clinically to improve pedicle screw fixation in the presence of compromised bone. Pedicle screws may be augmented with cement, but this may lead to cement leakage and result in disastrous consequences. To avoid these complications, a multiaxial expandable pedicle screw has been developed. This was a prospective, single-center study designed to evaluate the clinical results of patients with osteoporosis with traumatic and degenerative spinal diseases treated with expandable pedicle screws. METHODS Thirty-three patients (mean age 61.4 years) with osteoporosis and traumatic or degenerative spinal diseases underwent spinal posterior fixation with expandable screws. Preoperative and postoperative visual analog scale (VAS) for pain and Oswestry Disability Index (ODI) questionnaire scores were obtained. The immediate postoperative screw position was measured and compared with the final position on lateral plain radiographs and axial CT scans at the 1- and 2-year follow-up examinations. RESULTS A total of 182 pedicle screws were used, including 174 expandable and 8 regular screws. The mean preoperative patient VAS score improved from 8.2 to 3.6 after surgery. The mean ODI score improved from 83.7% before surgery to 29.7% after the operation and to 36.1% at the final follow-up. No screw migration had occurred at the 1-year follow-up, but 1 screw breakage/migration was visualized on spinal radiography at the 2-year follow-up. CONCLUSIONS The results of this study show that the multiaxial expandable pedicle screw is a safe and practical technique for patients with osteoporosis and various spinal diseases and adds a valuable tool to the armamentarium of spinal instrumentation.

Full Text Available Osteoporosis is a condition of bone fragility resulting from micro-architectural deterioration and decreased bone mass. Studies on the presence of a generalized osteoporosis related to diabetes mellitus (DM are few and controversial. Factors associated with osteoporosis diabetes in which may account for the patogenesis of diabetic bone loss have been studied. This article will review the relevant litarature relating to diabetes and osteoporosis including cellular and animal models. These studies include vascular and neuropathic mechanism, poor glisemic control, abnormalities of calcium and vitamin D metabolism and hypercalciuria with secondary increase in parathyroid hormone secretion, the role of insülin and insülin like growth factor I. It appears that there is a great deal of variability in the bone mineral density and fracture rates in both type I and type II DM. This may reflect multiple factors such as the population, age, duration of diabetes and insülin use. There is need for further longitudinal studies, including the incidence and risk factors for osteoporosis in DM.

Biochemical markers of bone turnover in the clinical development of drugs for osteoporosis and metastatic bone disease: potential uses and pitfalls.

Science.gov (United States)

Cremers, Serge; Garnero, Patrick

2006-01-01

Biochemical markers of bone turnover are used increasingly during the clinical development of drugs for the treatment of metabolic bone diseases such as Paget's disease, osteoporosis and cancer that has metastasised to the bone. However, assessing the optimal value of these markers is often complicated, and such an assessment is an obvious prerequisite for rational use of the markers and, consequently, potential improvement of clinical drug development. Biochemical markers of bone turnover are substances in the blood or urine that are produced or released during bone remodelling. They provide semiquantitative information on bone remodelling, and are often the most adequate tool to describe the pharmacodynamics of the drug. Their use has increased considerably because of dose-effect relationships that have been seen with certain drugs, but also because they have proven relationships with clinical outcomes in several metabolic bone diseases. However, there is a lack of information on the kinetics of these markers, and the immunoassays that are frequently used in their monitoring often measure a mixture of fragments rather than a single molecular entity. For drug development it should also be realised that different markers, but also different assays for the same marker, may provide different results, considerably limiting the ability to compare results. In postmenopausal osteoporosis, relationships have been shown between several biochemical markers of bone turnover, and either fracture risk and/or the antifracture efficacy of drugs. Such relationships can be used for the development of drugs with similar mechanisms of action, but also for the development of these drugs for closely related indications, such as corticosteroid-induced osteoporosis. In both of these instances, data on effects on biochemical markers of bone turnover are usually employed in combination with information about effects on bone mineral density. However, the relationships of these parameters

Interankle blood pressure (BP) difference has been associated with peripheral artery disease and adverse cardiovascular outcomes. However, the relationship between interankle BP difference and renal outcomes in chronic kidney disease (CKD) has never been evaluated. The purpose of this study was to determine whether interankle BP difference is associated with the rate of renal function decline and progression to renal end points in patients with stage 3-5 CKD. We enrolled 144 patients with CKD from one regional hospital. The BP in four limbs was simultaneously measured using an ABI-form device. The decline in renal function was evaluated using an estimated glomerular filtration rate (eGFR) slope. Rapid renal progression was defined as an eGFR slope < -3 mL/min per 1.73 m(2) per year. The renal end points were defined as ≥ 25% decline in eGFR or commencement of dialysis during the follow-up period. During a mean follow-up period of 3.1 years, 90 patients (62.5%) reached renal end points. Multivariate analysis showed that an increased interankle systolic BP difference (per 5 mmHg) was associated with a worse eGFR slope (regression β, -0.292; 95% confidence interval [CI], -0.482 to -0.102; P = 0.003), rapid renal progression (odds ratio, 1.189; 95% CI, 1.015-1.394; P = 0.032), and an increased risk of progression to renal end points (hazard ratio, 1.126; 95% CI, 1.052-1.204, P = 0.001). Interankle systolic BP difference was associated with rapid renal progression and progression to renal end points in patients with stage 3-5 CKD in our study. © 2015 Asian Pacific Society of Nephrology.

While occupational exposure to respirable silica is known to lead to lung disease, most notably silicosis, its association with chronic kidney disease is unclear. This review explores the association between occupational exposure to respirable silica and chronic non-malignant renal disease such as glomerulonephritis. The evidence has been collected and compiled. Possible sources of bias are thoroughly discussed. Cohort studies with silica exposure and case-control studies of renal disease were searched in PubMed until January 2015. Two authors independently abstracted data; any disagreement was resolved by consulting a third reviewer. A meta-analysis was performed to evaluate the association to silica exposure. A total of 23 cohort and four case-control studies were included in the analysis. The meta-analysis of cohort studies yielded elevated overall SMRs for renal disease. Some studies, however, included dose-response analyses, most of which did not show a positive trend. The approaches and results of the case-control studies were very heterogeneous. While the studies of cohorts exposed to silica found elevated SMRs for renal disease, no clear evidence of a dose-response relationship emerged. The elevated risk may be attributed to diagnostic and methodological issues. In order to permit a reliable estimation of a possible causal link, exposed cohorts should be monitored for renal disease, as the information from mortality studies is hardly reliable in this field.

Quantitative ultrasound (QUS) of the bone is a technique that is generating great interest among bone structure researchers because of its intrinsic features. Its safety and low cost make it an ideal technique for repeated measurements over time such as in chronic disease or when it is necessary to monitor the effects of prescribed therapies. The method was developed for the study of osteoporosis and the sites of measurement are all peripheral, including the distal diaphyses and metaphyses of the phalanges, calcaneus, radius and tibia. QUS parameters, however, cannot be used directly for the diagnosis of osteoporosis according to the WHO criteria, although many authors have shown that ultrasound parameters, particularly those of calcaneal QUS, can predict the risk of osteoporotic fractures independently of MBD. Very promising results with the use of QUS have been obtained in corticosteroid-induced osteoporosis, rheumatoid arthritis, Cushing's syndrome, cystic fibrosis, osteomalacia, thalassemia and osteopenia related to parenteral nutrition. QUS can also monitor the effectiveness of therapy in various pathological conditions. In nephrology the combined use of phalangeal QUS and biochemical markers of bone turnover allows adequate follow-up of patients on dialysis and renal transplant recipients with alterations or disorders of the bone.

Full Text Available Hypertension is a frequent, chronic cardiovascular disease both in industrially developed and developing countries; its frequency ranges between 20 and 40 %. Although the prevalence of hypertension in women is lower than that in men, it reaches 70% to 80% in women above 70 years of age, and is a strong predictor of cardiovascular risk. Osteoporosis (OP is systematic skeletal disorder with lower bone mass and damages of bone tissue microarchitecture. The aim of this study was to ascertain the association between hypertension and osteoporosis as two mass noninfectious deceases.The examination involved three hundred postmenopausal women who came for densitometry inspection; none of them had some major cardiovascular event (myocardial infarction, cerebrovascular stroke and ischemic heart disease. From all of them were taken personal data, personal and familial case histories. The parameters used in the further analysis were: body mass, body height, waist circumference, blood pressure; laboratory analysis: cholesterol, HDL, LDL, glycemia, Ca and P in serum and Ca in urine. In addition, there was calculated a ten-year risk of cardiovascular event according to SCORE system, using tables for high risk; bone mineral density on Hologic Discovery QDR-C was shown as T score on the lumbar part of the spinal column. The patients were divided into tree groups based on the measures of bone density: the patients with osteoporosis - bone density with T score lower than 2.5 SD (100 patients; patients with osteopenia - T score from -1 to -2,5 SD (100, and control group of patients with normal bone density T score from +1 to -1 SD (100.The mean age of postmenopausal women (control group with normal bone density was 54.10±3.90 years; 56.63±4.76 years in the group with osteopenia (group II; and 60.14±3.55 years in the group of postmenopausal women with osteoporosis.The analysis of variance (ANOVA and post hoc Dunett`s test showed that there were statistically

Hershberger, Kathleen A; Martin, Angelical S; Hirschey, Matthew D

2017-04-01

The coenzyme nicotinamide adenine dinucleotide (NAD + ) has key roles in the regulation of redox status and energy metabolism. NAD + depletion is emerging as a major contributor to the pathogenesis of cardiac and renal diseases and NAD + repletion strategies have shown therapeutic potential as a means to restore healthy metabolism and physiological function. The pleotropic roles of NAD + enable several possible avenues by which repletion of this coenzyme could have therapeutic efficacy. In particular, NAD + functions as a co-substrate in deacylation reactions carried out by the sirtuin family of enzymes. These NAD + -dependent deacylases control several aspects of metabolism and a wealth of data suggests that boosting sirtuin activity via NAD + supplementation might be a promising therapy for cardiac and renal pathologies. This Review summarizes the role of NAD + metabolism in the heart and kidney, and highlights the mitochondrial sirtuins as mediators of some of the beneficial effects of NAD + -boosting therapies in preclinical animal models. We surmise that modulating the NAD + -sirtuin axis is a clinically relevant approach to develop new therapies for cardiac and renal diseases.

Musculoskeletal diseases, especially osteoarthritis (OA) and osteoporosis (OP), impair activities of daily life (ADL) and quality of life (QOL) in the elderly. Although preventive strategies for these diseases are urgently required in an aging society, epidemiological data on these diseases are scant. To clarify the prevalence of knee osteoarthritis (KOA), lumbar spondylosis (LS), and osteoporosis (OP) in Japan, and estimate the number of people with these diseases, we started a large-scale population-based cohort study entitled research on osteoarthritis/osteoporosis against disability (ROAD) in 2005. This study involved the collection of clinical information from three cohorts composed of participants located in urban, mountainous, and coastal areas. KOA and LS were radiographically defined as a grade of > or =2 by the Kellgren-Lawrence scale; OP was defined by the criteria of the Japanese Society for Bone and Mineral Research. The 3,040 participants in total were divided into six groups based on their age: or =80 years. The prevalence of KOA in the age groups or =80 years 0, 9.1, 24.3, 35.2, 48.2, and 51.6%, respectively, in men, and the prevalence in women of the same age groups was 3.2, 11.4, 30.3, 57.1, 71.9, and 80.7%, respectively. With respect to the age groups, the prevalence of LS was 14.3, 45.5, 72.9, 74.6, 85.3, and 90.1% in men, and 9.7, 28.6, 41.7, 55.4, 75.1, and 78.2% in women, respectively. Data of the prevalence of OP at the lumbar spine and femoral neck were also obtained. The estimated number of patients with KOA, LS, and L2-L4 and femoral neck OP in Japan was approximately 25, 38, 6.4, and 11 million, respectively. In summary, we estimated the prevalence of OA and OP, and the number of people affected with these diseases in Japan. The ROAD study will elucidate epidemiological evidence concerning determinants of bone and joint disease.

We conducted a post-marketing observational study to investigate the safety and effectiveness of eldecalcitol for the treatment of osteoporosis in a Japanese clinical setting. The observation period was 12 months for women and 36 months for men. The final results for the female patients have already been published. In this article, the final results for the male patients are reported. A total of 470 male osteoporosis patients were enrolled. The safety analysis set included 431 patients (mean age, 76.8 years; mean ± SD follow-up period, 631.0 ± 450.3 days), and 175 patients continued treatment throughout the 3-year observational period. Adverse drug reactions (ADRs) were reported in 28 patients (6.49%); the most common ADRs were hypercalcemia (1.16%) and renal impairment (1.16%). Serious ADRs were reported in 5 patients (1.16%). Mean serum calcium was within the normal range throughout the observation period. The cumulative incidence of new vertebral and nonvertebral fractures at 36 months, estimated by Kaplan-Meier analysis, was 10.23 and 4.06%, respectively. At the last observation, mean lumbar spine bone mineral density was 3.49% higher (P effectiveness of eldecalcitol for the treatment of Japanese male osteoporosis patients was confirmed in clinical practice. Careful monitoring of serum calcium and estimated glomerular filtration rate, both before and during treatment, is necessary to minimize the risk of hypercalcemia and renal impairment while maximizing the effectiveness of eldecalcitol.

Osteoporosis: primary prevention in the community.

The incidence of osteoporosis is increasing worldwide. It has great impact on the life of the elderly population. The most significant medical consequence of osteoporosis is fragility fracture which without proper treatment will cause severe medical and psychosocial complications. The overall cost in managing osteoporosis and its related fractures is escalating. Using bone densitometry to measure bone mineral density is useful in the diagnosis of osteoporosis but it is costly and not feasible in the community. Drugs such as estrogen replacement, raloxifene and calcitonin are effective in prevention and treatment of osteoporosis but they are also expensive. Identifying modifiable risk factors such as smoking, lack of exercise, low dietary calcium and vitamin D intake and healthy life style remain strategy in the primary prevention of osteoporosis in the community.

Full Text Available It was reported that some proteins known to cause renal cystic disease (NPHP6; BBS1, and BBS4 also localize to the olfactory epithelium (OE, and that mutations in these proteins can cause anosmia in addition to renal cystic disease. We demonstrate here that a number of other proteins associated with renal cystic diseases - polycystin 1 and 2 (PC1, PC2, and Meckel-Gruber syndrome 1 and 3 (MKS1, MKS3 - localize to the murine OE. PC1, PC2, MKS1 and MKS3 are all detected in the OE by RT-PCR. We find that MKS3 localizes specifically to dendritic knobs of olfactory sensory neurons (OSNs, while PC1 localizes to both dendritic knobs and cilia of mature OSNs. In mice carrying mutations in MKS1, the expression of the olfactory adenylate cyclase (AC3 is substantially reduced. Moreover, in rats with renal cystic disease caused by a mutation in MKS3, the laminar organization of the OE is perturbed and there is a reduced expression of components of the odor transduction cascade (G(olf, AC3 and α-acetylated tubulin. Furthermore, we show with electron microscopy that cilia in MKS3 mutant animals do not manifest the proper microtubule architecture. Both MKS1 and MKS3 mutant animals show no obvious alterations in odor receptor expression. These data show that multiple renal cystic proteins localize to the OE, where we speculate that they work together to regulate aspects of the development, maintenance or physiological activities of cilia.

Full Text Available Severe osteoporosis is classified as those with a bone mineral density (BMD T-score of −2.5 or lower, and demonstrate one or more of osteoporotic, low-trauma, fragility fractures. According to the general principle of surgical approach, patients with severe osteoporosis require not only more thorough pre- and postoperative treatment plans, but improvements in surgical fixtures and techniques such as the concept of a locking plate to prevent bone deformity and maximizing the blood flow to the fracture site by using a minimally invasive plate osteosynthesis. Arthroplasty is often performed in cases of displaced femoral neck fracture. Otherwise internal fixation for the goal of bone union is the generally accepted option for intertrochanteric, subtrochanteric, and femoral shaft fractures. Most of osteoporotic spine fracture is stable compression fracture, but vertebroplasty or kyphoplasty may be performed some selective patients. If neurological paralysis, severe spinal instability, or kyphotic deformity occurs, open decompression or fusion surgery may be considered. In order to overcome shortcomings of the World Health Organization definition of osteoporosis, we proposed a concept of ‘advanced severe osteoporosis,’ which is defined by the presence of proximal femur fragility fracture or two or more fragility fractures in addition to BMD T-score of −2.5 or less. In conclusion, we need more meticulous approach for surgical treatment of severe osteoporosis who had fragility fracture. In cases of advanced severe osteoporosis, we recommend more aggressive managements using parathyroid hormone and receptor activator of nuclear factor kappa-B ligand monoclonal antibody.

Traditional serological biomarkers often fail to assess systemic lupus erythematosus (SLE) disease activity and discriminate lupus nephritis (LN). The aim of this study was to identify novel markers for evaluating renal and overall disease activity in Chinese patients with pediatric systemic lupus erythematosus (pSLE). The study included 46 patients with pSLE (35 girls, 11 boys; average age 13.3 ± 2.6 years) and 31 matched healthy controls (22 girls, 9 boys; average age 12.3 ± 2.4 years). The SLE Disease Activity Index (SLEDAI) and renal SLEDAI were used to assess disease activity. Nine different soluble mediators in plasma, including tumor necrosis factor alpha (TNF-α), platelet-derived growth factor-BB (PDGF-BB), interferon (IFN) gamma inducible protein 10 (IP-10), interleukin (IL)-1β, IFN-γ, IL-17A, IL-2, Fas and Fas ligand, were measured by Luminex assay and compared between patients with active and inactive pSLE as well as between patients with pSLE with active and inactive renal disease. Receiver operating characteristic curve analysis was used to measure the discrimination accuracy. Of the 46 patients with pSLE, 30 (65.2%) had LN. These patients had significantly elevated levels of serum TNF-α, PDGF-BB, IP-10 and Fas. The serum levels of IP-10 were also significantly higher in patients with active pSLE. We found that IP-10 was also more sensitive and specific than conventional laboratory parameters, including anti-double-stranded DNA and complement components C3 and C4, for distinguishing active lupus from quiescent lupus. The serum level of IP-10 was also significantly increased in children with pSLE with active renal disease relative to those with inactive renal disease. There was also a positive correlation between serum IP-10 levels and renal SLEDAI scores as well as with 24 h urine protein. Serum IP-10 is useful for identifying renal and overall disease activity in children with pSLE.

Inflammatory disease is associated with increased production of nitric oxide (NO) and activation of the inducible nitric oxide synthase (iNOS) pathway. Several studies have addressed the role of NO as a mediator of cytokine effects on bone cell activity in vitro. Stimulatory and inhibitory actions have been found, however, depending on the concentrations produced and model system used. In view of this, it has been difficult to predict whether increased production of NO during inflammation is likely to increase bone loss or prevent it. We have investigated the pathogenic role of NO in an animal model of inflammation-induced osteoporosis (IMO). NO production was increased in IMO when compared with controls (+344%; p turnover, but L-NMMA had no effect on bone mass in control animals. This study has important implications for many inflammatory diseases such as rheumatoid arthritis, ankylosing spondylitis, and inflammatory bowel disease which are associated with increased NO production and osteoporosis. Our data not only suggest that iNOS activation and increased NO production contribute to the pathogenesis of osteoporosis in these situations, but also suggest that NOS inhibitors could be of therapeutic value in the prevention and treatment of such bone loss.

Osteoporosis-Related Mortality: Time-Trends and Predictive Factors

Full Text Available Osteoporosis is one of the leading causes of handicap worldwide and a major contributor to the global burden of diseases. In particular, osteoporosis is associated with excess mortality. We reviewed the impact of osteoporosis on mortality in a population by defining three categories: mortality following hip fractures, mortality following other sites of fractures, and mortality associated with low bone mineral density (BMD. Hip fractures, as well as other fractures at major sites are all associated with excess mortality, except at the forearm site. This excess mortality is higher during the first 3-6 months after the fracture and then declines over time, but remains higher than the mortality of the normal population up to 22 years after the fracture. Low BMD is also associated with high mortality, with hazard ratios of around 1.3 for every decrease in 1 standard deviation of bone density at 5 years, independently of fractures, reflecting a more fragile population. Finally predictors of mortality were identified and categorised in demographic known factors (age and male gender and in factors reflecting a poor general health status such as the number of comorbidities, low mental status, or level of social dependence. Our results indicate that the management of a patient with osteoporosis should include a multivariate approach that could be based on predictive models in the future.

Full Text Available Jameela Banu Coordinated Program in Dietetics, College of Health Sciences and Human Services and Department of Biology, College of Science and Mathematics, University of Texas-Pan American, Edinburg, TX, USA Abstract: Men undergo gradual bone loss with aging, resulting in fragile bones. It is estimated that one in five men will suffer an osteoporotic fracture during their lifetime. The prognosis for men after a hip fracture is very grim. A major cause is reduction of free testosterone. Many other factors result in secondary osteoporosis, including treatment for other diseases such as cancer and diabetes. Patients should be screened not only for bone density but also assessed for their nutritional status, physical activity, and drug intake. Therapy should be chosen based on the type of osteoporosis. Available therapies include testosterone replacement, bisphosphonates, and nutritional supplementation with calcium, vitamin D, fatty acids, and isoflavones, as well as certain specific antibodies, like denosumab and odanacatib, and inhibitors of certain proteins. Keywords: risk factors, hormones, bisphosphonates, nutritional supplements, antibodies, protein inhibitors, male osteoporosis

End-stage renal disease in sub-Saharan and South Africa.

The major health problems in Africa are AIDS, tuberculosis, malaria, gastroenteritis and hypertension; hypertension affects about 20% of the adult population. Renal disease, especially glomerular disease, is more prevalent in Africa and seems to be of a more severe form than that found in Western countries. The most common mode of presentation is the nephrotic syndrome, with the age of onset at five to eight years. It is estimated that 2 to 3% of medical admissions in tropical countries are due to renal-related complaints, the majority being the glomerulonephritides. There are no reliable statistics for ESRD in all African countries. Statistics of the South African Dialysis and Transplant Registry (SADTR) reflect the patients selected for renal replacement therapy (RRT) and do not accurately reflect the etiology of chronic renal failure (CRF), where public sector state facilities will offer RRT only to patients who are eligible for a transplant. In 1994, glomerulonephritis was recorded as the cause of ESRD in 1771 (52.1%) and hypertension in 1549 (45.6%) of patients by the SADTR. In a six-year study of 3632 patients with ESRD, based on SADTR statistics, hypertension was reported to be the cause of ESRD in 4.3% of whites, 34.6% of blacks, 20.9% mixed race group and 13.8% of Indians. Malignant hypertension is an important cause of morbidity and mortality among urban black South Africans, with hypertension accounting for 16% of all hospital admissions. In a ten-year study of 368 patients with chronic renal failure in Nigeria, the etiology of renal failure was undetermined in 62%. Of the remaining patients whose etiology was ascertained, hypertension accounted for 61%, diabetes mellitus for 11% and chronic glomerulonephritis for 5.9%. Patients with CRF constituted 10% of all medical admissions in this center. Chronic glomerulonephritis and hypertension are principal causes of CRF in tropical Africa and East Africa, together with diabetes mellitus and obstructive

Fabry disease related patients with classical mutation usually exhibit similar severe phenotype especially concerning renal manifestation. A dry blood spot screening (DBS) and the DNA analysis has been performed in a 48-year-old man (Patient 1) because of paresthesia. The DBS revealed absent leukocyte α -Gal A enzyme activity while DNA analysis identified the I354K mutation. Serum creatinine and e-GFR were in normal range and also albuminuria and proteinuria were absent. The brain MRI showed ischemic lesions and a diffuse focus of gliosis in the white matter, while the echocardiogram showed a left ventricular hypertrophy. The renal biopsy performed in the case index showed a massive deposition of zebra bodies. By a familiar investigation, it was recognized that his brother (Patient 2) died 2 years before from sudden death syndrome at the age of 49. He had suffered sporadic and undiagnosed pain at the extremities, a prior cataract, bilateral neurosensorial hearing loss and left ventricular hypertrophy on Echocardiogram. His previous laboratory examinations revealed a normal serum creatinine and the absence of proteinuria. Pedigree analysis of the brothers revealed a high disease burden among family members, with an affected cousin (Patient 3) who progressed early to end-stage renal disease (ESRD) that required renal transplantation. Here we describe the clinical history of three adult male members of the same family with the same genotype who manifested different presentation and progression of the disease, particularly concerning the renal involvement.
