The Relationship

Abstract Background and Aims Vascular calcification (VC) is associated to morbidity and mortality in chronic kidney patients. However, it remains to clarify the relationship between VC and renal osteodystrophy (ROD) evaluated by bone biopsy in peritoneal dialysis (PD) patients. Method In order to characterize the relationship between VC and ROD in prevalent PD population, we performed tetracycline-labelled bone biopsies with histomorphometric analysis according KDIGO guidelines. Hands and pelvis x-ray were performed to evaluate VC and to calculate Adragão Score. Exclusion criteria: previous kidney transplant, hemodialysis, treatment with agents interfering in bone metabolism (for example bisphosphonates). All patients were treated with biocompatible PD solutions, with calcium concentration of 1.25 mmol/L. Results Thirty-one patients participated in the study. Mean age was 52.32±11.09 years, 16 male, 6 with diabetes mellitus (DM), 22 on manual PD, median time on PD was 12 (3-61) months. Mean calcium, phosphate and PTH were 9.2±0.5 mg/dL, 4.9±1.0 mg/dL and 486.0±230.5 pg/mL, respectively. Most frequent diagnosed ROD pattern was adynamic bone disease (44.4%) followed by hiperparathyroid bone disease (33.3%) and normal bone (14.8%). VC was detected in 29% of patients and mean Adragão score was 1.13. However, 100% of diabetics had VC on x-ray compared to 12% of non-diabetics. Clinical, analytical and histomorphometric essential data is represented in table 1: Also no significant differences were observed between the patients with or without VC in ROD patterns on bone biopsy, glucose load in PD solutions, prescribed phosphate binders namely calcium-based binders, active vitamin D or calcimimetics. In diabetic patients, bone volume tended to be lower (17.26% vs 22.54%; p=0.072) comparing to non-diabetics. Bone formation rate was similar in diabetics and non-diabetics (25.39 vs 27.71µm3/µm2/y) as mineralization lag time (18.7 vs 20.1 days). Conclusion ROD evaluated by bone biopsy and the proportion of PD patients with VC on x-ray were similar to previous reports. However, in the present study a striking difference in VC was detected in diabetics – all diabetic patients had VC demonstrated radiographically. This finding was not explained by differences in calcium, phosphate, PTH levels or other studied factors. So DM could be a strong risk factor to VC in this population. Also, patients with VC were older, with higher sedimentation rate and lower total KT/V. It is possible that diabetic patients represent a different subgroup, particularly prone to lower bone volume and specially VC. They might benefit from higher dialysis dose and aggressive approaches to prevent or retard VC. This remains to be proved in properly designed prospective studies. In conclusion, age, sedimentation rate, total KT/V and presence of diabetes were associated to VC in prevalent PD patients. Diabetics may be a subgroup of PD patients with very high risk of VC.

Abstract Background and Aims Renal transplant and associated immunosuppression can influence bone volume. The aim of this study was to analyze the relations between bone biopsy data and levels of bone-related molecules [phosphorus (Pi), Calcium (Ca), Magnesium (Mg), parathyroid hormone (PTH), bone alkaline phosphatase (bAP), calcitonin, vitamin D (vitD), alpha-klotho, fibroblast grow factor (FGF) 23, sclerostin], obtained 1-year after transplantation with bone densitometry findings in the same time point in renal transplanted patients. Method We performed a prospective cohort study of a consecutive sample of de novo single renal transplanted patients in our unit. At inclusion, demographic, clinical and transplant-related data were collected, X-ray of the pelvis and hands (Adragão score) and echocardiographic findings were recorded. All patients were submitted to a laboratorial evaluation and a bone biopsy at baseline. Patients were followed for 12 months, after which performed laboratorial evaluation, 2nd bone biopsy, echocardiogram, X-ray of pelvis and hands, bone densitometry (DXA) and non-contrast cardiac CT. For this report we use the information of the 2nd analysis: laboratorial information, bone histology information, as well the densitometry evaluation. Continuous variables were presented as medians and categorical variables as frequencies. Associations between variables were performed using Wilcoxon rank-sum test, Fisher exact test, Kruskal Wallis rank test or Spearman correlation test. Multivariate analysis was performed using linear regression models. STATA software was used and p < 0.05 was considered statistically significant. Results We recruited 84 patients and, at the end of 12 months, we performed a 2nd evaluation in 69 patients. Median age 53 years, 48 men, 53 caucasian (78.8%), median BMI 24.6, median dialysis vintage 55 months. Patients had a median cumulative steroid dose of 5692.5 mg. Analyzing bone biopsies, we found that 28 patients had adynamic bone disease; 6 had hyperparathyroid bone disease; 2 had osteomalacia and 3 other abnormal mineralization; 8 patients presented only with osteoporosis. There was no significant difference between bone volume / total volume pre transplant (18%) and 1 year after transplantation (19%). Using DXA technique, 14 patients were classified has having osteoporosis, and all those had low volume at the bone biopsy. Nevertheless, in 4 patients low bone turnover was also present. The positive predictive value dropped from 100% to 57%, if we add the other abnormalities of bone, in addiction to the volume. DXA exam wasn’t a good tool to detect a normal bone volume, as the negative predicted value dropped from 78% (normal volume, irrespective of turnover and mineralization) to 37% (normal bone biopsy). Nevertheless, overall bone volume assessed by a bone biopsy correlated well with densitometry findings. Conclusion DXA exam isn’t a good tool to identify the bone quality. Nevertheless, once osteoporosis is detected the probability of the patient having low bone volume is high, but we still need a bone biopsy in order to exclude mineralization or turnover deviations.

Bone Disorder

Bone disease is one of the most challenging complications in patients with chronic kidney disease. Today, it is considered to be part of a complex systemic disorder manifested by disturbances of mineral metabolism and vascular calcifications called chronic kidney disease – mineral bone disorder (CKD-MBD). The term renal osteodystrophy is reserved to define the specific bone lesion in CKD-MBD, whose spectrum ranges from high turnover to low turnover disease. Phosphate retention, decreased serum calcium, and 1,25-dihydroxy vitamin D synthesis are involved in the pathogenesis of high bone turnover. However, the various therapeutic approaches (calcium supplements, phosphate binders, and vitamin D metabolites, among others), the renal replacement modality (hemodialysis or continuous ambulatory peritoneal dialysis), and the types of patients to whom dialysis is offered (more patients who are diabetic or older, or both) may influence the evolution of the bone disorder. As a result, recent studies have reported a greater prevalence of adynamic forms of renal osteodystrophy, especially in diabetic and peritoneal dialysis patients. The present article reviews, for patients treated with peritoneal dialysis, the pathophysiologic mechanisms involved in the evolution and perpetuation of this bone disease and the therapeutic modalities for treating and preventing adynamic bone.

Abstract Background and Aims The spectrum of renal osteodystrophy (ROD) in peritoneal dialysis (PD) patients remains to be clarified. Most studies are old and the results inconsistent. Also there were changes in clinical practice that may have influenced the bone histology in PD patients. Method In order to characterize ROD in prevalent PD population, we performed tetracycline-labelled bone biopsies in 49 PD patients with histomorphometric analysis according KDIGO guidelines. Exclusion criteria: history of kidney transplant, hemodialysis, treatment with agents interfering in bone metabolism (for example bisphosphonates). Hands and pelvis x-ray were performed to evaluate vascular calcification (VC) and to calculate the Adragão score. All patients were treated with biocompatible PD solutions, with calcium concentration of 1.25 mmol/L. Results Forty-nine patients participated in the study, with 32 biopsies analyzed so far. Mean age was 52.4±10.9 years, 16 male, 6 with diabetes mellitus, 23 on manual PD, median time on PD was 22.1 (3-61) months. Mean calcium, phosphate and PTH were 9.2±0.5 mg/dL, 4.9±1.0 mg/dL and 489.87±227.8 pg/mL, respectively. Vascular calcification was detected in 29% of patients and mean Adragão score was 1.13. Essential histomorphometric and selected data is represented in table 1: Bone volume (BV) tended to be lower in diabetics - 17.1% (10.1-23.1) compared with non-diabetics – 22.6% (12.7-41.4) (p=0.07). Median bone formation rate (BFR) tended to be lower - 21.39 µm3/µm2/y (8.2-53.2) in diabetic patients than in non-diabetics - 28.63 µm3/µm2/y (3.5-89.77) (p=0.80). PTH levels also tended to be lower in diabetics – 384.8 pg/mL compared to non-diabetics – 514.1 pg/mL (p=0.14). BV tended to be lower in patients with VC – 19.1% (10.1-27) compared with patients without VC - 22.6% (12.7-41.4) (p=0.23). VC was detected on x-ray in all 6 patients with diabetes and only in 11.5% (3 in 26) of non-diabetic patients. Conclusion Similar to previous reports, the most frequent ROD pattern was ABD. However, PD patients with ABD had mean PTH of 405 pg/mL, a value well within the recommended KDIGO targets. This reinforces PTH as a far from ideal marker of bone turnover and suggests different targets for PTH levels in this seemingly highly susceptible population to ABD even when treated with low calcium dialysate. The proportion of patients with normal bone was higher than previously published. This finding can be explained by differences in the classification of ROD and prescription of biocompatible PD solutions in all patients. Diabetic patients tended to have lower BV and BFR. This finding is not surprising considering osteoblastic toxicity caused by advanced glycation end products. Also diabetic patients have a state of relative hypoparathyroidism. In conclusion, the most frequent pattern was ABD. Diabetic patients on PD may be a different subgroup.

To examine the relationship between dialysis modality and prognosis in Japanese patients, we conducted a prospective multicenter observational study. We recruited 83 background-matched peritoneal dialysis (PD) and 83 hemodialysis (HD) patients (average age, 64.9 years; men, 53.6%; diabetic patients, 22.9%; median duration of dialysis, 48 months in all patients) and followed them for 5 years. During the follow-up period, 27 PD patients (16 cardiovascular and 11 non-cardiovascular deaths) and 27 HD patients died (14 cardiovascular and 13 non-cardiovascular deaths). There were 8 PD patients switched to HD, and 6 PD patients received renal transplantation. Kaplan-Meier analysis revealed that the crude survival rate was not significantly different at the end of 5 years (PD 67.5% versus 67.5%, log-rankP=0.719). The difference in cardiovascular and non-cardiovascular mortalities between PD and HD was not statistically significant. Multivariate Cox analysis showed that the independent predictors for death were age and serum albumin levels, but not the dialysis modality. This study showed that the overall mortality was not significantly different between PD and HD patients, which suggests that dialysis modality might not be an independent factor for survival in Japanese patients.

Objective We investigated the clinical condition and complications of patients on peritoneal dialysis (PD) and on hemodialysis (HD) for more than 12 years. Design This retrospective review was carried out in the renal unit of the Tung Wah Hospital, Hong Kong. Patients and Methods Of 103 HD and 341 PD patients who started dialysis before 1990, 14 HD and 22 PD patients were dialyzed for more than 12 years. We evaluated basic demography at the 12th year of dialysis and at the most recent follow-up, and assessed the prevalence of cardiovascular disease, bone disease, dialysis-related amyloidosis (DRA), and acquired cystic disease (ACD). Outcomes and mortality were recorded. Results The 36 patients in the study included 22 women and 14 men. The PD patients were older ( p = 0.021) and had lower levels of serum phosphate and calcium × phosphate product. Only 3 patients were diabetic. Cardiovascular disease was present in 30 patients (83.3%), the most common types being ischemic heart disease (IHD, n = 11) and left ventricular hypertrophy (LVH, n = 22). Symptomatic DRA was found in 13 patients (36.1%), more commonly in the HD group ( p = 0.014). Bone disease was present in 32 patients (88.9%), with parathyroidectomy being more frequently performed in the PD patients ( p = 0.048). Symptomatic ACD occurred in 5 patients (13.9%). At the most recent follow-up, 26 patients were still on dialysis, 3 patients had undergone renal transplantation, and 7 patients had died, the causes of death being sudden death ( n = 3), cerebrovascular accident ( n = 1), chest infection ( n = 2), and peritonitis ( n = 1). Patient survival was similar in the PD and HD groups. Age at commencement of dialysis predicted mortality ( p = 0.012), but mode of dialysis, sex, and presence of diabetes mellitus did not. Conclusions Long-term survival is possible for both dialysis modalities (PD and HD), particularly for young, non diabetic patients. Symptomatic DRA is less common in PD patients, but the prevalence of other long-term complications is similar for both groups. Cardiovascular-related problems remain the leading cause of death.

♦ BackgroundThere have been no reports on peritoneal dialysis (PD) solution utilization since this treatment was developed in the 1920s. The aim of the present investigation was to investigate if weather affects PD prescription.♦ Study Design and MethodsThis 10-year observational study used the Taiwan National Health Insurance Research Database. Setting and Participants: Claims for different concentrate PD dialysate were analyzed monthly. 2.5% and 4.25% PD solutes were defined as hypertonic solutions. Predictor: Monthly outdoor mean temperature. Outcome and Measurement: The relationship between monthly mean of PD dialysate utilization and monthly outdoor temperature was analyzed by linear regression. Monthly mean PD dialysate utilization amount in 4 quarters was analyzed by ANOVA.♦ ResultsDuring the 10-year study period, a clear seasonal variation in PD dialysate was observed. This seasonal variation was present regardless of age, gender, and the presence of hypertension, diabetes, and dyslipidemia. Monthly mean temperature was positively correlated to 1.5% dialysate utilization amount ( r = 0.559, p < 0.001) and negatively correlated to 2.5% ( r = –0.533, p < 0.001) and 4.25% ( r= –0.410, p < 0.001) dialysate utilization amount. In longitudinal follow-up, hypertonic PD fluid utilization was higher in diabetic patients than in nondiabetic patients from the beginning of treatment. Thereafter, it increased rapidly and reached a plateau within 1 year. Limitations: Analysis of ultrafiltration amount, blood pressure, and body weight was unfeasible due to the nature of the database.♦ ConclusionsThe utilization of differential strengths of PD solutions has a seasonal cyclic pattern, with more hypertonic PD solution utilized in winter and more hypotonic PD solution in summer.

Abstract Background and Aims Chronic kidney disease and especially end stage renal disease are important public health issues with increasing incidence and significant economic burden. Despite advances in peritoneal dialysis (PD), mortality is still high mostly because of cardiovascular morbidity and mortality. The aim of the present study was to identify prognostic risk factors for cardiovascular death in non-diabetic PD patients. Method We performed a prospective study in which we included non-diabetic patients in stable PD programme for at least 6 months. Clinical, biological, heart and carotid ultrasound and arterial stiffness (evaluated through applanation tonometry) parameters were analysed. Independent risk factors for cardiovascular death were identified by logistic regression using IBM SPSS ver. 20.0. Results We included 246 consecutive non-diabetic patients (118F, 128M), mean age 56.3 + 15.7 years (20-85). Mean follow up was 6.5+1.1 years. 36 patients (14.6%) died because of cardiovascular reasons - sudden cardiac death 13 patients, acute coronary syndrome 8 patients, ischemic stroke 8 patients, and heart failure 7 patients. Individuals with cardiovascular death were significantly older (64.6±14.2 vs 54.7±15.5 years, p=0.01), with signs of malnutrition, inflammation and associated anemia - significantly lower total cholesterol (150.2±43.0 vs 194.3±58.2 mg/dl, p=0.002), serum albumin (2.9±0.4 vs 3.5±0.7 g/dl, p=0.002) and hemoglobin (9.7±1.1 vs 10.7±1.4 g/dl, p=0.007) and significantly higher serum fibrinogen (568.7±121.3 vs 509.8±115.0 mg/dl, p=0.04) and C-reactive protein (6.7+1.2 vs 9.5+0.9 mg/l, p=0.02). In univariate analysis risk for cardiovascular death was higher in patients with renal hypertensive disease (OR 4.0, 95%CI 1.4-11.5, p=0.01), iPTH serum level &lt;150 pg/ml (OR 6.6, 95%CI: 2.3-18.9, p&lt;0.001), left ventricular hypertrophy (OR 10.6, 95%CI 2.3-18.9, p=0.001) and diastolic dysfunction (OR 4.0, 95%CI 1.2-14.9, p=0.02). Compared to patients with an iPTH between 150-300 pg/ml, both patients with lower iPTH and also higher iPTH had an increased risk for cardiovascular death (OR=1.6, 95%CI: 1.2-2.0; p&lt;0.001 for iPTH&lt;150 pg/ml, and OR =1.2, 95%CI:1.04-1.34; p=0.01 for iPTH&lt;300 pg/ml). Patients with cardiovascular death had signs of subclinic atherosclerosis- intima-media thickness at carotid level &gt;0.9 mm (OR 4.3, 95%CI 1.1-16.3, p=0.02) and higher pulse wave velocity as a sign of increased arterial stiffness (11.9+2.5 vs 8.6+2.6 m/s, p=0.04). After adjusting for potential confounders, independent predictive factors for cardiovascular death were male gender, calcium-phosphate product&gt;55 mg2/dl2, iPTH&lt;150 pg/ml and peripheral arterial disease (Table 1). Conclusion We found an increased risk for cardiovascular death in non-diabetic PD patients, mostly because of sudden cardiac death. Malnutrition, inflammation, but especially abnormal mineral metabolism (both increased calcium-phosphate product and low bone turnover) were identified as risk factors for cardiovascular death and are potentially treatable risk factors to improve cardiovascular outcome in PD patients. A better understanding of pathogenesis and risk factors for cardiovascular death in PD may help improve patients’ management and thus their long-term survival.

OBJECTIVE: To better explore the relationship between parameters of glycemic control of T2DM in RRT, we studied 23 patients on hemodialysis (HD), 22 on peritoneal dialysis (PD), and compared them with 24 T2DM patients with normal renal function (NRF). MATERIALS AND METHODS: We performed, on four consecutive days, 10 assessments of capillary blood glucose [4 fasting, 2 pre- and 4 postprandial (post-G) and average (AG)], random glycemia, and HbA1c in all patients. RESULTS: Preprandial blood glucose was greater in patients on RRT compared with NRF. Correlations between AG and HbA1c were 0.76 for HD, 0.66 for PD, and 0.82 for NRF. The regression lines between AG and HbA1c were similar for patients on HD and with NFR, but they were displaced upward for PD. CONCLUSION: Similar HbA1c values in PD patients may correspond to greater levels of AG than in HD or NRF patients.

BackgroundBetter glycemic control has been reported to slow the progression of nephropathy in predialysis diabetic patients. However, the relationship between glycemic control and residual renal function (RRF) in patients on peritoneal dialysis (PD) is uncertain.Methods89 incident diabetic patients on PD were recruited from 5 centers. We measured glomerular filtration rate (GFR) and hemoglobin A1c (HbA1c) within 2 months (baseline) after the start of PD and at 6 and 12 months. GFR was calculated as the average of renal creatinine and urea clearances. We analyzed whether mean HbA1c was associated with change in GFR (ΔGFR) over 1 year.ResultsDuring the first year of PD, ΔGFR was -1.7 ± 3.4 mL/min/1.73 m2and was not affected by mean HbA1c. Acute hemodialysis before starting PD and mean arterial diastolic pressure were related to the decline of GFR in a multivariate analysis.ConclusionGlycemic control was not associated with change in RRF in diabetic patients during the first year after starting PD.
