Chronic kidney disease (CKD) and hypertension are very common chronic diseases. Active and standardized treatment of hypertension in patients with CKD can not only delay the progress of renal disease, but also reduce the risk of cardiovascular events. In recent years, although the guidelines for hypertension have put forward detailed suggestions for the management of hypertension in CKD patients, there are differences in the recommendation of blood pressure target value for CKD patients. Combined with the latest guidelines, this review interprets the blood pressure measurement methods, diagnostic criteria, antihypertensive targets and drug therapy in patients with CKD.
Elderly patients with chronic kidney disease not only suffer from senescence-related muscle strength decline, but also exist muscle attenuation caused by chronic kidney disease. Sarcopenia of this group are more obvious, and falls, incapacity, weakness and death caused by sarcopenia are more prominent. At present, clinicians’ understanding of sarcopenia is still in the aspects of concept popularization and basic research, and there is a lack of practical diagnosis and treatment process and clinical prevention and treatment practice. Starting from the evolution of the definition of sarcopenia, this paper elaborates on the characteristics of sarcopenia in elderly patients with chronic kidney disease, as well as the exercise rehabilitation of sarcopenia in elderly patients with chronic kidney disease, in order to improve the attention and understanding of renal colleagues on sarcopenia in elderly people with chronic kidney disease.
ObjectiveTo explore the nutritional status of inpatients with chronic kidney disease (CKD) and analyze the factors affecting nutritional risk, to provide theoretical basis for further nutritional support.MethodsConvenience sampling method was adopted to select 719 inpatients with CKD as research subjects in a tertiary hospital in Chengdu, Sichuan Province from January to March 2018. Nutritional Risk Screening 2002 was used for nutritional risk screening, and chi-square test, t test, one-way analysis of variance, and multiple linear regression analysis were used to explore the influencing factors of nutritional risk.ResultsAmong the 719 cases, whose average nutritional risk score was 1.79±1.11, 158 cases had nutritional risk, accounting for 22.0%. There were statistically significant differences in nutritional risk score between patients of age<60 years and ≥60 years, between males and females, between patients with CKD stage 1-3 and stage 4-5, between patients with serum albumin level <30 g/L and ≥30 g/L, and between patients with and without anaemia (P<0.05). The results of multiple linear regression analysis showed that the nutritional risk score of CKD patients was negatively correlated to serum albumin level (P=0.016), positively correlated to age (P<0.001), and higher in females than that in males (P=0.001).ConclusionsInpatients with CKD have a higher nutritional risk, with age, gender and serum albumin as the main influencing factors. Based on the above factors, the medical staff should continue to take targeted intervention measures to assess the nutritional status of CKD inpatients early and conveniently, so as to provide scientific basis for further nutritional support and nutritional nursing.
ObjectiveTo evaluate the screening performance of commonly used renal function indicators for chronic kidney disease (CKD) in subjects of different ages, so as to explore the appropriate screening regimen for Chinese population.MethodsA total of 2 131 adult subjects in Sichuan Orthopaedic Hospital or Mianyang Central Hospital from May 2016 to October 2017 were selected. They were divided into three groups according to age: group A (18–39 years, n=278), group B (40–64 years, n=1 167), and group C (≥65 years, n=686). Serum levels of creatinine (SCr), urea, and cystatin C [CysC; to calculate estimated glomerular filtration rate (eGFR) based on this index], as well as urine levels of albumin, total protein and creatinine were measured, and urine albumin to creatinine ratio (ACR) and urine protein to creatinine ratio (PCR) were calculated respectively. CKD was diagnosed according to the Kidney Disease: Improving Global Outcomes (KDIGO) Guideline (2012 Edition). The receiver-operating characteristic (ROC) curve analysis was finally performed to investigate the diagnostic performance of each indicator for CKD.ResultsThe prevalences of CKD in group A, B, and C were 10.8% (30/278), 16.4% (191/1 167), and 45.8% (314/686), respectively, and the difference among these groups was statistically significant (χ2=233.525, P<0.001). In addition, the levels of the six renal function indicators between CKD and non-CKD subjects also had statistically significant differences in different age groups (P<0 05="" otherwise="" roc="" curve="" analysis="" revealed="" that="" the="" diagnostic="" values="" of="" these="" indicators="" were:="" acr="" or="" pcr=""> eGFR or CysC > serum urea or SCr (AllP<0 05="" except="" that="" egfr="" cysc="" serum="" urea="" and="" scr="" in="" group="" a="" assessed="" the="" similar="" diagnostic="" performance="" among="" the="" three="" indicators="" recommended="" by="" kdigo="" guideline="" the="" diagnostic="" performances="" of="" acr="" and="" pcr="" in="" different="" age="" groups="" were:="" group="" b="" 0="" 915="" 0="" 914=""> group A (0.885, 0.890) > group C (0.841, 0.846), while the diagnostic performance of eGFR was group C (0.807) > group B (0.728) > group A (0.696). The best boundary values of ACR and PCR were lower while the value of eGFR was higher than the corresponding KDIGO recommended medical decision levels.ConclusionsACR is the first choice for screening CKD when the renal function index creatinine is normal. Moreover, eGFR can further improve the diagnostic value, especially in subjects over 65 years old.
Chronic kidney disease (CKD) has become an important public health problem that seriously affects the physical and mental health of Chinese people. Nutritional therapy has become one of the important treatments for CKD. Domestic and international guidelines for CKD clinical nutrition therapy have been introduced, and the intake of various nutrients in CKD patients, especially protein intake, has been guided. In recent years, with the continuous development of nutrition assessment and treatment, the content of the guidelines has gradually improved, but some views are still controversial. This article explains the relevant guidelines for the treatment of CKD at home and abroad to provide reference for the clinical nutritional treatment of CKD patients.
Objective To investigate the current status of health promoting lifestyle in maintenance hemodialysis (MHD) patients and to explore its correlation with chronic illness resource utilization. Methods Patients who underwent outpatient MHD in the Hemodialysis Room of the Department of Nephrology, West China Hospital, Sichuan University between January and March 2023 were selected. Patients were surveyed using the General Information Questionnaire, Chronic Illness Resource Survey, and Health Promoting Lifestyle Profile-Ⅱ Revise. Results A total of 158 patients were surveyed. MHD patients scored 103.37±18.52 on health promoting lifestyle, and 68.95±14.14 on chronic illness resource utilization. The Pearson correlation analysis results showed that there was a positive correlation between the chronic illness resource utilization and the total score of health promoting lifestyle in MHD patients (r=0.765, P<0.001), as well as scores in all dimensions (P<0.05). The results of multiple linear regression analysis showed that the main caregivers being parents [non-standardized partial regression coefficient (b)=8.150, 95% confidence interval (CI) (0.804, 15.497), P=0.030], weekly dialysis times [b=10.701, 95%CI (2.787, 18.615), P=0.008], and chronic illness resource utilization [b=0.936, 95%CI (0.800, 1.072), P<0.001] were influencing factors for health promoting lifestyle. Conclusions MHD patients have an average health promoting lifestyle, and ideal chronic illness resource utilization. Hemodialysis nurses can take targeted measures to enhance chronic illness resource utilization and health promoting lifestyle in MHD patients, which can further improve the quality of life of MHD patients.
ObjectivesTo evaluate the methodological bias and the reliability of the conclusions of systematic reviews (SRs) of lanthanum carbonate in the treatment of chronic kidney disease with hyperphosphatemia. MethodsWe electronically searched databases including PubMed, EMbase, The Cochrane Library, PROSPERO, CNKI, CBM, WanFang Data and VIP to collect systematic reviews and meta-analysis about lanthanum carbonate in the treatment of chronic kidney disease with hyperphosphatemia from inception to August 31st, 2016. Two reviewers independently screened literature and extracted data, then AMSTAR tool was used to assess the methodological quality of included studies and the GRADE tool was used to grade the evidence quality of outcome measures included in the SRs. ResultsA total of eight relevant SRs were included and containing three main outcome measures. The assessment results of AMSTAR tool suggested that:four SRs were of high quality, and the other four were of medium quality. GRADE results showed:for serum phosphorus level, compared with placebo, the quality of the evidence of three SRs were medium, low and very low; compared with calcium carbonate or conventional phosphorus binder, four SRs were low, low, low and very low; compared with sevelamer, one SR was low. For serum calcium level, compared with placebo, the quality of the evidence of three SRs were high, medium and low, respectively; compared with calcium carbonate or conventional phosphorus binder, five SRs were low, low, low, very low and very low; compared with sevelamer, one SR was very low. For serum iPTH level, compared with placebo, the quality of the evidence of three SRs were medium, low and very low; compared with calcium carbonate or conventional phosphorus binder, five SRs were medium, low, low, very low and very low; compared with sevelamer, one SR was low. ConclusionAt present, methodological quality assessment for the treatment of hyperphosphatemia in chronic kidney disease with lanthanum carbonate is generally not high and the level of evidence for the conclusion is generally low. In drug safety, especially in the occurrence of adverse events of the digestive system is still controversial, and a large amount of high quality experimental is needed to demonstrate the safety of its long-term use. Clinicians need to be cautious in using these evidence to make clinical decisions.
Objective To investigate the nutritional status of hospitalized patients with chronic kidney disease (CKD), analyze the influencing factors, and construct a predictive model to provide a localized theoretical basis and more convenient risk prediction indicators and models for clinical nutrition support and intervention treatment of CKD patients in China. Methods Convenience sampling was used to select hospitalized CKD patients from Department of Nephrology, West China Hospital, Sichuan University, from January to October 2019. General information questionnaires, the Nutritional Risk Screening 2002 scale, and the Huaxi Emotional-distress Index questionnaire were used for data collection. Single factor analyses and multiple logistic regression analysis were conducted to explore the risk factors for malnutrition in CKD hospitalized patients. A predictive model was established and evaluated using receiver operating characteristic (ROC) curve analysis and bootstrap resampling. Results A total of 1059 valid copies of questionnaires were collected out of 1118 distributed. Among the 1059 CKD hospitalized patients, 207 cases (19.5%) were identified as having nutritional risk. The multiple logistic regression analysis showed that CKD stage [odds ratio (OR)=1.874, 95% confidence interval (CI) (1.631, 2.152), P<0.001], age [OR=1.015, 95%CI (1.003, 1.028), P=0.018], and the Huaxi Emotional-distress Index [OR=1.024, 95%CI (1.002, 1.048), P=0.033] were independent risk factors for malnutrition in CKD hospitalized patients, while serum albumin [OR=0.880, 95%CI (0.854, 0.907), P<0.001] was an independent protective factor. The evaluation of the multiple logistic regression analysis predictive model showed a concordance index of 0.977, standard deviation of 0.021, and P<0.05. The area under the ROC curve was 0.977. Conclusions The prevalence of malnutrition is relatively high among CKD hospitalized patients. CKD stage, age, psychological status, and serum albumin are influencing factors for malnutrition in CKD hospitalized patients. The multiple logistic regression model based on the above indicators demonstrates good predictive performance and is expected to provide assistance for early nutritional intervention to improve the clinical outcomes and quality of life for CKD patients with malnutrition in China.
ObjectiveTo investigate the health literacy level and its influencing factors among follow-up patients with chronic kidney disease (CKD).MethodsFrom March to August 2018, 248 patients from the CKD Follow-up Management Center, West China Hospital, Sichuan University were included. Basic information questionnaire and chronic diseases health literacy scale were used. Analysis of variance and t test were used in univariate analysis, and multiple linear stepwise regression was used in multivariate analysis, to explore the influencing factors of health literacy score.ResultsThe average health literacy score of the 248 CKD patients (97.24±12.22) were in medium to low level. Listed from high to low, the score of each dimension was: ability to obtain information (4.24±0.50), willingness to improve health (4.17±0.66), competence to communicate and interact with others (3.95±0.59), and willingness to support financially (3.41±1.10). The result of multiple linear stepwise regression showed that whether followed up on time, families’ monthly income per capita, and the patients’ age were independent influencing factors of health literacy score (P<0.05).ConclusionsThe health literacy level of follow-up patients with CKD remains to be improved. Medical personnel should pay attention to whether patients with CKD are followed up on time, make targeted intervention, and improve the self-management of patients so as to delay the disease progress of CKD.
End-stage renal disease is a late complication of chronic kidney disease (CKD) and one of the leading causes of high mortality worldwide. Over the years, the impacts of gut microbiota and their associated uremic toxins on kidney diseases through the intricate “gut-kidney axis” have been extensively studied. However, translation of microbiome-related omics results into specific mechanisms is still a significant challenge. In this paper, we review the interaction between gut microbiome and blood purification, as well as the current microbiota-based therapies in CKD. Additionally, the current sequencing technologies and progresses in the gut microbiome research are also discussed.
