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.
Objective To assess the effectiveness and safety of erythropoietin (EPO) for cancer-related malignant anemia without radiotherapy or chemotherapy. Methods Randomized controlled trials (RCTs) or quasi-randomized controlled trials (quasi-RCTs) involving erythropoietin in the treatment of cancer-related malignant anemia were searched and identified from PubMed (1966 to Sept. 2009), EMBASE (1974 to Sept. 2009), The Cochrane Library (Issue 3, 2009), CBM (1978 to Sept. 2009), CNKI (1994 to Sept. 2009), VIP (1989 to Sept. 2009). We also handsearched relevant journals. Data were extracted and evaluated by two reviewers independently with specially designed extraction form. We evaluated the quality of the included studies by the Cochrane Handbook 5.0 recommend standard and analyzed data by Cochrane Collaboration’s RevMan 5.0. Results We included twelve trials. The quality of the included studies was poor. The grade of ten studies was B, and the grade of two studies was C. Meta-analyses showed that there were significant differences between erythropoietin and blank in volume of blood transfusion [SMD= –0.66, 95%CI (–1.14, –0.17), P=0.008], number need to transfusion [OR=0.60, 95%CI (0.39, 0.92), P=0.02], and the change of hemoglobin after two-week therapy [SMD=2.40, 95%CI (0.29, 4.52), P=0.03]. Conclusion The current evidence shows that EPO significantly benefits cancer-related malignant anemia. Well-designed RCTs with a larger sample size, longer intervention and follow-up periods are still needed.
Autoimmune hemolytic anemia (AIHA) is an autoimmune disease in which the life span of red blood cells is shortened by red blood cell autoantibodies. Due to immune intolerance and abnormal immune regulation, the hyperfunction of B lymphocytes produces too many red blood cell autoantibodies. Anti-CD20 monoclonal antibody is a second-line drug for warm antibody AIHA and first-line drug for cold antibody AIHA by reducing B lymphocytes. At present, the optimal dose of anti-CD20 monoclonal antibody in the treatment of AIHA has not been determined. There are no reports on the treatment of primary AIHA with second- or third-generation anti-CD20 monoclonal antibodies.
【Abstract】 Objective To report 1 case of acute hemolytic anemia after liver transplantation because of ABO compatibility and therapeutic experience. Methods The patient with liver cancer underwent orthotopic piggyback liver transplantation on September 2010 after radiofrequency ablation of the tumors. The donor and recipient ABO blood types were type O and type A, separately. Acute hemolytic anemia occurred at 10 days after transplantation and hemoglobin decreased to 56 g/L. The bone marrow showed active hyperplasia; and myeboid∶erythroid was 0.52∶1. The immunosuppressants were used and type O washed red blood cells were transfused immediately. Results The general condition of the patient was improved; hemoglobin increased gradually and returned to 111 g/L at 34 days after liver transplantation. At 12 months of follow-up, hemoglobin was within normal range. Conclusion Using graft blood type washed red blood cells transfusion and immunosuppressants could be an effective therapeutic procedure in the patient with ABO compatility graft when acute hemolytic anemia occurrs.
ObjectiveTo analyze the clinical effect of sodium chlorophyllin in the treatment of geriatric oncology-related anemia and its significance. MethodsWe retrospectively analyzed the clinical data of elderly cancer patients with similar treatment background between December 2011 and February 2013, and the patients were divided into sodium chlorophyllin treatment group and no special treatment group. Then, parallel comparative study was carried out for anemia-related indexes and scores of quality of life. ResultsHemoglobin, red blood cells and quality of life of sodium chlorophyllin treatment group were improved after treatment, and these indexes were also better than those in the no special treatment group (P<0.05). ConclusionSodium chlorophyllin can ameliorate anemia in elderly patients with oncology-related anemia, which is worthy of being popularized.
Objective To assess the effectiveness and safety of cyclosporine A (CsA) for aplastic anemia (AA) in China. Methods Randomized controlled trails (RCTs) of CsA for AA were collected from CBMdisc (1978 to 2008), CNKI (1979 to 2008), and VIP (1989 to 2008). Other relevant journals were also hand searched. The methodological quality of included studies was evaluated, and data analyses were performed with The Cochrane Collaboration’s software RevMan 4.2.0. Results A total of 19 RCTs were included. As for the total effective rate and complete remission rate, significant differences were noted between CsA + androgen vs. androgen alone, CsA + androgen combination vs. androgen combination, as well as CsA + androgen + other drugs vs. androgen + other drugs [total effective rate: RRs and 95%CIs were 1.48 (1.28 to 1.70), 1.67 (1.17 to 2.39), and 1.51 (1.09 to 2.08); complete remission rate: RRs and 95%CIs were 2.06 (1.33 to 3.19), 3.52 (1.19 to 10.39), and 1.54 (1.00 to 2.38)]. Conclusion According to the domestic evidence, treatment with CsA for AA may improve the total effective rate and complete remission rate. However, more high quality clinical trials are expected for further study.
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.
We reported one case of MTX-induced aplastic anemia and reviewed related literature to investigate the mechanism of action of MTX, and summarize the clinical feature, diagnostic criteria, risk factor, and interventions. These were hoped to arouse the attention of clinicians and clinical pharmacists, in order to effectively prevent, diagnose, and treat MTX-induced aplastic anemia.
Objective To assess the clinical effectiveness and safety of astragalus injection plus androgen versus androgen alone for patients with aplastic anemia (AA). Methods Such databases as The Cochrane Library (Issue 3, 2011), PubMed (1966 to March 2011), EMbase (1974 to March 2011), CNKI (1994 to March 2011), VIP (1989 to March 2011) and Wanfang Data (1997 to March 2011) were searched to include the randomized controlled trails (RCTs) according to the inclusive and exclusive criteria. The data were extracted, the quality was assessed, and meta-analysis was conducted by using Revman5.0.24 software. Results Seven RCTs involving 518 patients with AA were included. The meta-analysis showed that the astragalus plus androgen treatment group was superior to the androgen alone group in the total effective rate with significant difference (OR=3.12, 95%CI 2.09 to 4.66, Plt;0.000 01); the adverse events in the treatment group were fewer than those in the control group with significant difference (OR=0.30, 95%CI 0.12 to 0.76, P=0.01); but the promotion degree of myelosis between the two groups was similar without significant difference (OR=1.93, 95%CI 0.85 to 4.38, P=0.11). Conclusion The astragalus plus androgen treatment is superior to the androgen alone treatment in the total effective rate and fewer adverse events. More high-quality trails are required to verify this conclusion due to the low quality and small scale of the included studies.
ObjectiveTo investigate the clinical features, diagnosis, treatment and prognosis of pulmonary tumor thrombotic microangiopathy (PTTM).MethodsA patient with PTTM was reported. Literatures about PTTM searched by WanFang databases and PubMed were reviewed for its clinical characteristics.ResultsA 62-year-old female was admitted with chief complaint of dry cough, dyspnea and hemoptysis. Progressive dyspnea, pulmonary hypertension and hypoxemia occurred during hospitalization. Computed tomography angiography (CTA) of the lung excluded pulmonary embolism. Peripheral blood appearing a large number of late erythroblasts and erythrocyte debris and progressively decreasing platelets suggested that the patient suffer from thrombotic microvascular disease. CT showed widely metastatic lesions at the vertebrae and sternum. On the basis of above clinical characteristics, PTTM was diagnosed clinically. Although the patient accepted respiratory support therapy, anticoagulation therapy and resuscitation, she still died 5 days later after hospitalization. Literatures about PTTM with complete clinical information were reviewed. A total of 92 PTTM cases were reviewed and the main reasons of these patients admitted were progressive dyspnea and chronic cough. During hospitalization, they all suffered varying degrees of hypoxia, while radiological findings of the lungs lack specificity. No abnormal sighs were found by lung CTA. The results of ultrasonic cardiography or the Swan–Ganz catheter indicated varying degrees of pulmonary hypertension, some patients were proved with disseminated intravascular coagulation and/or microangiopathic hemolytic anemia. The definite diagnosis of PTTM depended on the histologic evidence which were often obtained from post-mortem examination, because many patients couldn’t tolerate the lung biopsy due to rapid aggravation. The treatment of PTTM included respiratory support therapy, anticoagulation therapy, antipulmonary hypertension and the chemotherapy of primary or metastatic tumour. The prognosis of PTTM was poor and almost all of the patients died in a short term, ranged from 48 hours to 3 months.ConclusionIf a patient with a history of cancer or evidence of cancer metastasis has hypoxemia and pulmonary hypertension but without abnormal lung CTA signs, PTTM should be considered.
