Malnutrition-inflammation-atherosclerosis (MIA) syndrome components in hemodialysis and peritoneal dialysis patients

BACKGROUND: Malnutrition, inflammation, and atherosclerosis (MIA syndrome) are common in end-stage renal disease (ESRD) patients. Each component of MIA syndrome is the predictor of outcomes in ESRD patients. In this cross-sectional study, we aimed to compare both dialysis modalities for MIA syndrome components. MATERIAL AND METHODS: Thirty hemodialysis (HD) (mean age 44 +/- 11 years, 14 male and 16 female, mean time on dialysis: 31.0 +/- 19.0 months) and 30 continuous ambulatory peritoneal dialysis (CAPD) patients (41 +/- 9 years, 12 male and 18 female, mean time on dialysis: 25.5 +/- 21.5 months) were included. In order to determine malnutrition in ESRD patients, serum albumin level and anthropometric measurements were used. For inflammation, serum C-reactive protein level, erythrocyte sedimentation rate, and fibrinogen levels were measured. Mean-carotid artery intima media thickness (m-CIMT), presence of carotid plaque and serum homocysteine level were used to determine atherosclerosis. RESULTS: Five CAPD patients (16%) and one HD patient (3%) was hypoalbuminemic. HD and CAPD groups were similar for inflammation. Mean-CIMT and serum homocysteine level were higher in HD patients than CAPD patients. There was a positive correlation between homocysteine and m-CIMT. CONCLUSION: Before choosing renal replacement therapy, malnutrition, inflammation, and atherosclerosis parameters must be investigated in ESRD patients. Hemodialysis seems to be more advantageous for malnutrition components than CAPD. Both dialysis modalities seem to be similar for inflammation, and CAPD modality has superiority for atherosclerosis. Before choosing the type of renal replacement therapy, assessment of MIA syndrome components could be useful for individualization of the decision on which dialytic modality is appropriate in ESRD patients.     

HLA antigens and serum ferritin in hemodialysis patients

The evolution of serum ferritin levels in 111 chronic-hemodialysis patients is prospectively studied. Patients were classified in two groups according to the presence or absence of 'hemochromatosis antigens' (HLA A3, B7 or B14) in their HLA typing. Levels of serum ferritin were similar in both groups before they started dialysis and during the first year. On the contrary, in the second and third hemodialysis years serum ferritin was higher in the group carrying 'hemochromatosis antigens'. These differences were observed in patients treated with parenteral iron either in the form of transfusions or as intravenous dextran-iron but not in patients receiving oral iron. We conclude that the risk of developing iron overload is greater in hemodialysis patients with HLA A3, B7 or B14. Nevertheless, this potential risk can be minimized with a restrictive policy on the use of parenteral iron (transfusions, intravenous dextran-iron).     

维持性血液透析患者血清骨保护素与肾性骨营养不良的关系

骨保护素（OPG）是近年来在肿瘤坏死因子受体超家族中发现的一种具有调控破骨细胞产生和活化作用的生物活性物质。它与核因子κB活化子受体配体（RANKL,亦称骨保护素配体OPGL）和核因子κB活化子受体（RANK）组成的分子调控系统是体内维持骨代谢平衡的重要分子机制。在正常的骨转化中成骨细胞表面表达RANKL．它与破骨细胞前体或破骨细胞表面的RANK结合后启动了信号转导，使破骨细胞增殖和活化．溶骨活动增强。同时成骨细胞分泌OPG，它与RANK竞争性的抑制RANKL使溶骨作用不致过度强烈。     

维持性血液透析患者血氨基末端脑钠肽前体水平与肾性贫血的相关性

目的探讨维持性血液透析(MHD)患者发生肾性贫血的危险因素,分析其与血氨基末端脑钠肽前体(NT⁃proBNP)的相关关系。方法选取2018年8月至2018年11月期间在复旦大学附属华山医院接受MHD 3个月以上、病情稳定的患者为研究对象。按照血红蛋白(Hb)水平分为贫血组和非贫血组。回顾性收集患者一般资料、观察期内实验室检查及透析相关资料。Pearson相关分析法分析贫血指标与透析相关指标、血NT⁃proBNP水平的相关性;逐步多元线性回归法分析MHD患者发生贫血的危险因素。结果共160例MHD患者入选本研究,年龄(63.11±11.35)岁,男79例(49.4%),女81例(50.6%)。患者透析龄(118.01±82.32)个月,血红蛋白(110.09±13.48)g/L,NT⁃proBNP水平中位数为3985 ng/L。贫血组73例(45.6%),非贫血组87例(54.4%),贫血组血NT⁃proBNP水平显著高于非贫血组(t=-3.714,P<0.001)。MHD患者血红蛋白水平与每周透析时间(r=0.228)和血白蛋白(r=0.349)呈正相关,与血NT⁃proBNP水平呈负相关(r=-0.318);血细胞比容与每周透析时间(r=0.283)、血清钙(r=0.317)、血磷(r=0.264)、白蛋白(r=0.513)呈正相关(均P<0.05)。逐步多元线性回归分析结果显示,低血白蛋白、高NT⁃proBNP水平是MHD患者发生肾性贫血的独立危险因素。结论MHD患者NT⁃proBNP水平升高与血红蛋白水平降低相关,低血白蛋白、高NT⁃proBNP是MHD患者发生贫血的危险因素。提示肾性贫血的治疗需要考虑改善营养不良和高容量等因素。

Importance of serum ferritin levels in patients with renal failure

Study results on acute phase reactants of renal failure patients are controversial. In this study, we enrolled 39 patients and divided them into 2 groups: acute renal failure (ARF), and chronic renal failure (CRF) patients. As opposed to CRF patients, the patients with ARF had higher serum ferritin levels that were independent of anemia parameters and other acute phase reactants.     

Blood leukocyte contribution to serum ferritin levels in patients on chronic hemodialysis

Serum ferritin level has been shown by many investigators to be a good indicator of bone marrow iron stores in normal subjects. Although this correlation may hold in some pathological situations, it is lost in others. In leukemia a dissociation has been observed between serum ferritin levels and bone marrow iron stores. Leukemic cells were demonstrated to contain high levels of ferritin and to secrete it in the serum, causing this dissociation. In this study we investigated the possibility of having an analogous situation in patients on chronic hemodialysis. The latter patients have normal or high ferritin levels irrespective of bone marrow iron stores. Our results show that blood neutrophils and lymphocytes do not contribute to the high serum ferritin levels in these patients. Ferritin level in blood monocytes, however, was found to correlate with the serum ferritin levels and bone marrow iron stores in dialysis patients. Hence we concluded that sources other than blood leukocytes must be contributing to the high serum ferritin level in these patients. On the other hand, to unravel the role played in these changes by the monocytic cell population requires dynamic studies.

Relationship between anemia and clinic outcomes in maintenance hemodialysis patients

Objective To analysis the relationship between anemia and clinic outcomes retrospectively in maintenance hemodialysis patients for Renji Hospital, Shanghai Jiao Tong University School of Medicine, China. Methods This study enrolled all maintenance hemodialysis（MHD）patients between 1 January, 2007 and 31 December, 2014 at the Renji Hospital. They were followed up until death, cessation of hemodialysis, transfer to other centers or to the end of the study (31 December, 2014). Laboratory parameters, including hemoglobin concentrations, transferrin saturation, ferritin, serum albumin, were measured every 3 months. According to the Kidney Disease Outcomes Quality Initiative (K/DOQI) guidelines, the patients were divided into target-hemoglobin group (110≤Hb ≤120 g/L) and non target-hemoglobin group ( 120 g/L), and then the compliance rate of Hb, Ferritin, transferrin saturation, and the influence factors of compliance rate of Hb as well as its relationship with the prognosis were analyzed. Results Total 517 maintenance hemodialysis patients were involved in this study. The mean age was (63.76±14.78) years and 59.96% patients were male. Only 35.20%, 91.26% and 31.18% of them met the K/DOQI defined targets for hemoglobin, transferrin saturation and ferritin levels. The average levels of TSAT and Ferritin had no significant difference between the target-hemoglobin group and the non target-hemoglobin group. Compared with patients in non target-hemoglobin group, the target-hemoglobin group had significantly higher qualified rate of transferrin saturation (94.97% vs 89.41%, P=0.045) and Ferritin (37.22% vs 28.13%, P=0.036). Multivariate logistic regression analysis showed that the serum albumin, blood intact parathyroid hormone (iPTH) and dialysis vintage were independent risk factors that affected whether hemoglobin was up to the target. Kaplan-Meier analysis showed that the 8-year survival rate and cardiovascular survival rate in target-hemoglobin group were obviously higher than that in the non target-hemoglobin group (86.70% vs 75.30%, χ2Log rank=7.134, P=0.008; 93.80% vs 85.30%, χ2Log rank=6.134, P=0.013, respectively). Dialysis frequency, age and ferritin were independent risk factors of all-cause mortality for non target-hemoglobin group, and Dialysis frequency was independent risk factors of cardio-cerebral vascular disease mortality for non target-hemoglobin group. Conclusions The compliance rate of hemoglobin in MHD patients is still not steady controlled. Blood iPTH, serum albumin and dialysis vintage are independent risk factors that affect whether hemoglobin is up to the target in MHD patients. Sub-standard hemoglobin increases both all-cause mortality and cardio-cerebral vascular disease mortality in MHD patients.
