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.
With the increasing number of chronic kidney disease (CKD) population globally, establishing an optimal model of CKD care has become an important issue. The major contents of CKD care include patient education, control of CKD risk factors (such as increased blood pressure and glucose), management of CKD complications, and preparation process of renal replacement therapy in pre-dialysis patients. Compared with other non-communicable diseases management, evidence-based evidence related to CKD care is limited. Based on the related studies worldwide, combined with the characteristics of CKD population and previous experiences in China, this paper discusses the management mode of non-dialysis CKD population.
ObjectiveTo investigate the role of multiple disciplinary team (MDT) during surgical treatment of renal secondary hyperparathyroidism (SHPT), and identify management points of Departments of Nephrology and Endocrinology.MethodsThe data of patients with chronic kidney disease undergoing surgical treatment for SHPT in West China Hospital of Sichuan University between January 2009 and December 2018 were retrospectively collected. We explained the surgical treatment of MDT in the management of renal SHPT, and compared the changes before and after the establishment of MDT.ResultsA total of 187 patients including 101 males and 86 females were enrolled, with an average age of (47.60±11.28) years old and median dialysis vintage of 7 years. Under MDT, the number of patients with parathyroidectomy increased [(8.50±5.10) vs. (59.50±2.12) patients/year, P<0.001] and the completion rate of preoperative examinations were greatly improved (P<0.001). The success rate of surgery was also increased (86.8% vs. 97.5%, P=0.010). Proportion of patients who were admitted to the Department of Nephrology was significantly increased (39.7% vs. 84.9%, P<0.001). Most patients after surgery were transferred to the Department of Endocrinology (5.9% vs. 77.3%, P<0.001) to manage postoperative complications and metabolic bone disease, and thus normalized the management of SHPT.ConclusionsThe MDT contributes to management of renal SHPT, which is worthy of popularization and spreading. The management of internal medicine departments during surgical treatment of SHPT based on MDT is important, because they can be helpful to complete preoperative examinations and preoperative preparation as well as to alleviate postoperative complications.
Objective To investigate the prevalence and risk factors of sleep-disordered breathing (SDB) in patients with different severity of chronic kidney diseases (CKD). Methods A total of 144 patients of non-dialysis CKD patients in nephrology unit were recruited in the study. The patients were divided into CKD 1-2 period, CKD 3-4 period, and CKD5 period according to the severity of renal function. Results The prevalence of moderate SDB in CKD 1-2 period, CKD 3-4 period and CKD5 period were 30.0%, 53.5% and 60.5%, respectively (P=0.03), the prevalence of nocturnal hypoxemia were 23.3%, 56.3% and 65.1%, respectively ( P=0.001), and the prevalence of excessive daytime sleepiness (EDS) were 33.3%, 57.7% and 62.8%, respectively (P=0.032). Logistic regression analysis showed that age, male, body mass index (BMI), hypertension, diabetes and heart failure were independent risk factors for CKD merged with moderate to severe SDB, and the highest risk factor was heart failure (OR=7.034, 95%CI 1.255-39.420). Compared with CKD 1-2 period and CKD 3-4 period, the risk degree of CKD5 period was higher (OR=3.569 95%CI 1.324-9.620). Correlation analysis showed that glomerular filtration rate (eGFR) was negatively correlated with sleep apnea-hypopnea index (AHI) (r=–0.327, P=0.000). Conclusions There is a high prevalence of SDB (predominantly obstructive) in CKD patients and the increased risk of SDB is significantly associated with decreased eGFR among these patients. Associated comorbidities in CKD patients, especially for cardiac dysfunction, are important risk factors for SDB.
Objective To systematically review the effect of allopurinol on renal function in patients with chronic kidney disease (CKD). Methods The PubMed, EMbase, Cochrane Library, WanFang Data, CNKI, and VIP databases were searched for randomized controlled trials (RCTs) of the effect of allopurinol on renal function in patients with CKD. Databases for articles published between establishment of the database and April 28, 2021 were searched. Two evaluators independently screened the literature, extracted data and evaluated the risk of bias of the included studies. RevMan 5.4 was then used for meta-analysis. Results A total of 20 RCTs comprising 2 338 patients were included. The results of meta-analysis showed that compared with the control group, allopurinol substantially reduced the serum uric acid (MD=?2.48, 95%CI ?3.08 to ?1.89, P<0.01). In addition, the effect of allopurinol on slowing the decline in eGFR was influenced by the serum uric acid concentration. Participants taking allopurinol whose serum uric acid concentrations were maintained at >6 mg/dL showed a slower decline in eGFR (MD=5.03, 95%CI 1.76 to 8.31, P<0.01). However, there was no difference in the decline in eGFR between the two groups when the serum uric acid concentration of the participants was <6 mg/dL. Among participants with CKD and moderate renal dysfunction at baseline, those taking allopurinol showed a slower decline in eGFR than controls (MD=3.33, 95%CI 1.14 to 5.52, P<0.01). A further subgroup analysis showed that those who maintained their serum uric acid concentration above 6 mg/dL experienced a slower decline in eGFR (MD=5.46, 95%CI 2.06 to 8.86, P<0.01). However, when the serum uric acid concentration was <6 mg/dL, there was no difference between the allopurinol and control groups. Moreover, the serum creatinine concentration of the allopurinol group was lower than that of the control group after the intervention (MD=?0.39, 95%CI ?0.58 to ?0.19), P<0.01). However, there was no significant difference in the incidence of progression to end-stage kidney disease between the two groups (RR=0.96, 95%CI 0.65 to 1.42, P=0.85). Conclusion Allopurinol can substantially reduce serum uric acid and may protect the kidneys of patients with CKD when the serum uric acid concentration is maintained above 6 mg/dL.
Studies of evidence-based medicine have provided much important evidence, clarified problems, and guided the clinical practice in the treatment of renal diseases. As examples, several therapeutic problems in renal hypertension, renal anemia and low protein diet for the patients with chronic kidney disease are discussed in this paper.
ObjectiveTo explore the current status of treatment adherence in patients with chronic kidney disease without dialysis and to analyze its influencing factors.MethodsThe patients who visited the Outpatient Department of Nephrology of West China Hospital of Sichuan University from September to December 2020 were taken as the research objects. Self-designed general information questionnaire, treatment adherence questionnaire, physician-patient communication satisfaction, health information seeking behavior questionnaire, and physician-patient concordance questionnaire were used to investigate, and path analysis was used to explore the influencing factors of treatment adherence.ResultsA total of 203 valid questionnaires were obtained. Treatment adherence score was (21.69±2.42) points, self-reported health status was (2.48±0.91) points, physician-patient concordance was (20.39±2.70) points, physician-patient communication satisfaction was (67.73±5.52) points, and health information seeking behavior was (13.17±2.65) points. Health information seeking behavior (r=0.214, P=0.002), physicians-patient concordance (r=0.494, P<0.001), physician-patient communication satisfaction (r=0.229, P=0.001) were positively correlated with treatment adherence. Self-reported health status was negatively correlated with treatment adherence (r=?0.225, P=0.001). Path analysis showed that physicians-patient concordance was the most influencing factor of treatment adherence (total effect=0.474).ConclusionHealth information-seeking behavior and physicians-patient concordance are important factors affecting treatment adherence in chronic kidney disease patients without dialysis. In order to improve treatment adherence of chronic kidney disease patients, healthcare providers can provide various ways to provide information, which can help make more disease-related health knowledge available to patients. Moreover, healthcare workers should also further explore ways to improve the concordance related to reaching agreement between doctors and patients on medical and treatment options.
In 2020, chronic kidney disease has become one of the top 10 causes of death in the world. More and more evidence shows that proper exercise rehabilitation is beneficial to the health of patients with chronic kidney disease, which can improve the survival rate and slow down the decline of renal function. However, existing studies have significant differences in form, intensity, duration, and specific implementation methods of sports rehabilitation, which need to be further standardized and unified. This article introduces the impact of exercise rehabilitation on patients with chronic kidney disease and the clinical application of Chinese traditional exercises in patients with chronic kidney disease, and mainly discusses the application experience of exercise rehabilitation characterized by “Three-in-one Taiji” in the Department of Nephrology of West China Hospital of Sichuan University. It aims to provide a basis for the model innovation of integrated management of chronic kidney disease in China.
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.
