目的 分析持續腹膜透析患者發生腹膜炎的情況及相關因素，降低腹膜透析患者腹膜炎發生率、退出率，提高患者的生存率、生活質量。 方法 回顧分析2011年1月－6月收治的41例在家中行持續非臥床性腹膜透析且發生腹膜炎患者的臨床資料，觀察腹膜炎的發生率及轉歸，腹膜炎癥狀出現后初始的處理，對腹膜炎的誘因進行分析。 結果 41例腹膜透析患者共發生腹膜炎43例次，痊愈35例（85.4%），轉血液透析3例（7.3%），死亡3例（7.3%）。在癥狀出現初期，3例（7.3%）患者繼續在家觀察，10例（24.4%）患者立即到當地就醫，15例（36.6%）患者采用電話咨詢，13例（31.7%）患者到腹膜透析中心就診；18例（43.9%）患者直接將腹膜透析引流液帶到醫院進行藥敏試驗。就感染誘因而言，16例（39.0%）患者未嚴格進行空氣消毒，13例（31.7%）患者未嚴格進行環境清潔，10例（24.4%）患者操作過程存在污染行為。 結論 加強對居家行腹膜透析患者的初次培訓、操作指導及監測，可避免腹膜炎的發生，提高患者生活質量。
ObjectiveTo investigate the status of roxadustat in patients undergoing maintenance peritoneal dialysis and analyze the factors affecting drug compliance. MethodsPatients with renal anemia undergoing maintenance peritoneal dialysis in West China Hospital of Sichuan University from July 2020 to March 2021 were selected. All patients took roxadustat orally. According to the medication compliance, the patients were divided into good compliance group and poor compliance group. The general information questionnaire and Morisky Medication Adherence Scale-8 (MMAS-8) were used to investigate and analyze the included patients, and their clinical examination indexes were collected. ResultsA total of 100 patients were included, Including 39 cases (39%) in the good compliance group and 61 cases (61%) in the poor compliance group. The average score of medication compliance of roxadustat was 5.19±1.72. Logistic regression analysis showed that drug cognition [odds ratio (OR)=0.099, 95% confidence interval (CI) (0.027, 0.365), P=0.001], medication troubles/complex protocol [OR=5.330, 95%CI (1.567, 18.132), P=0.007], and adverse drug reactions [OR=5.453, 95%CI (1.619, 18.368), P=0.006] were factors affecting patient compliance. Hemoglobin in the good compliance group was lower than that in the poor compliance group (Z=?2.259, P=0.024); there was no significant difference in other clinical examination indexes (P>0.05). ConclusionsThe overall compliance of oral roxadustat in maintenance peritoneal dialysis patients is poor, and the corresponding follow-up management system should be improved. Nurses should provide comprehensive and systematic medication guidance to patients, encourage them to fully understand the clinical manifestations, treatment schemes and prognosis of renal anemia, clarify the time, dose, possible adverse reactions and mitigation methods of roxadustat, etc., and help them to treat the disease with correct cognition and attitude, so as to improve their drug compliance.
目的 比較兩種不同方法護理腹膜透析患者導管出口處的效果。 方法 選取2008年7月－2009年12月51例患者作為試驗組，直接采用聚維酮碘溶液擦洗導管出口處，2007年1月－2008年7月45例患者作為對照組，先用生理鹽水清洗遂道口，再用聚維酮碘溶液擦洗導管出口處。比較兩組導管出口處感染的情況及操作所需時間。 結果 試驗組出口評分系統（ESS）＜2分15例，2～3分34例，≥4分7例；對照組＜2分10例，2～3分24例，≥4分16例；兩組差異有統計學意義（P＜0.05）。試驗組護士操作時間為（3.0 ± 1.0）min，患者操作時間為（5.0 ± 1.5）min；對照組護士操作時間為（8.0 ± 2.0）min，患者操作時間為（10.0 ± 2.0）min；兩組差異有統計學意義（P＜0.05）。 結論 聚維酮碘溶液直接清洗、消毒導管出口處降低了感染的發生率，減少了操作環節和所需物品，縮短了操作時間。
ObjectivesTo explore the association between initial peritoneal transport characteristics and patient survival, and to evaluate the risk factors for mortality of continuous ambulatory peritoneal dialysis (CAPD) patients.MethodsBetween January 2011 and December 2016, the patients diagnosed with end stage renal disease commencing CAPD in West China Hospital were enrolled. According to the value of dialysate to plasma ratio for creatinine at 4 hour [D/P Cr (4 h)], CAPD patients were divided into two groups: the lower transport group [D/P Cr (4 h)<0.65] and the higher transport group [D/P Cr (4 h)≥0.65]. The survival of these two groups of peritoneal dialysis patients were plotted using survival analysis. CAPD patient outcomes were analyzed using multivariable Cox proportional hazards regression models.ResultsCompared with the lower transporter (n=246), higher transporter (n=345) were older, and with more peritoneal protein loss, lower level of serum albumin, lower level of hemoglobin, and less ultrafiltration (P<0.001). Higher transport group had lower survival rate compared to those in the lower transport group (P=0.001). The 1-, 3- and 5-year patient survival rates were 97.0%, 83.2%, and 71.7% in the higher transport group, and 98.7%, 93.9%, and 86.1% in the lower transport group, respectively. There was a positive relationship between D/P Cr (4 h) and serum peritoneal protein loss (P<0.001). D/P Cr (4 h) was inversely related to serum albumin (P<0.001). Cox regression analysis demonstrated that lower albumin [hazard ratio (HR)=0.921, 95% CI (0.885, 0.958), P<0.001], presence of cardiovascular disease [HR=1.996, 95% CI (1.256, 3.173), P=0.003], elder age [HR=1.049, 95% CI (1.033, 1.065), P<0.001], lower hemoglobin [HR=0.988, 95% CI (0.976, 1.000), P=0.044] and lower urea clearance index (KT/V)[HR=0.680, 95%CI (0.465, 0.994), P=0.046] could independently predicted mortality with significance in CAPD patients. But higher peritoneal transport was not a risk factor for mortality [HR=1.388, 95%CI (0.829, 2.322), P=0.212] in either model including serum albumin.ConclusionsFor CAPD patients, initial higher transporter had a higher mortality than lower transporter. However, initial higher peritoneal transport was not a risk factor for mortality independent of serum albumin in CAPD patients. Relationship between D/P Cr (4 h) and serum peritoneal protein loss and serum albumin suggests that higher peritoneal transport characteristics might worsen prognosis by lowering serum albumin level at initiation of peritoneal dialysis.
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.
Objective To investigate the change of pathogenic distribution and drug resistance in peritoneal dialysis associated peritonitis (PDAP). Methods The clinical data of all the patients undergoing continuous ambulatory peritoneal dialysis and suffered from PDAP between January and December in 2014 was retrospectively collected, and the pathogens, drug resistance, outcomes and underlying causes were analyzed. Results A total of 64 patients had 72 cases of PDAP. Only 36 strains (50.0%) had positive culture results, among which 24 strains (66.7%) were Gram-positive bacteria strains, 7 strains (19.4%) were Gram-negative bacteria strains, and 5 strains (13.9%) were fungi. For Gram-positive bacteria strains, the resistance rates to vancomycin, linezolid and rifampicin were all 0%; the resistance rate to levofloxacin, gentamycin and cefazolin was 14.3%, 26.3% and 50.0%, respectively. For Gram-negative bacteria strains, the resistance rates to amikacin and imipenem were both 0%; the resistant rate to gentamycin, ceftazidime, levofloxacin and ampicillin was 28.6%, 28.6%, 42.9% and 100.0%, respectively. Conclusions The pathogenic spectrum and drug resistance in PDAP have been markedly changed. Selection of antibiotics should be chosen according to the characteristic of the pathogenic spectrum and drug resistance of each center. Great effort is still needed to improve the culture positive rate of the effluent dialysate and to improve the recovery rate of peritonitis.
