ObjectiveTo investigate the incidence of perioperative anemia and the influencing factors of preoperative anemia in patients with colorectal cancer.MethodsThe clinicopathological data of 1 250 patients with colorectal cancer who underwent surgery in our hospital from January 1, 2019 to December 31, 2019 were analyzed retrospectively. According to the preoperative hemoglobin level, patients were divided into anemia group and non-anemia group. Univariate analysis and multivariate logistic regression analysis were used to explore the influencing factors of preoperative anemia in patients with colorectal cancer, and the effects of preoperative anemia on intraoperative blood transfusion, postoperative complications, and postoperative hospital stay were analyzed.ResultsThe incidence of preoperative anemia in patients with colorectal cancer was 40.6% (508/1 250), and the incidence of preoperative anemia in patients with right colon cancer, left colon cancer, and rectal cancer was 66.0% (192/291), 41.1% (139/338), and 28.5% (177/621), respectively. The incidence of postoperative anemia in patients with colorectal cancer was 69.4% (867/1 250), and the incidence of postoperative anemia in patients with right colon cancer, left colon cancer, and rectal cancer was 81.8% (238/291), 68.9% (233/338), and 63.8% (396/621), respectively. Multivariate logistic regression analysis showed that age >60 years old, nutritional risk screening 2002 ≥3, right colon cancer, T3–4 stage, and M1 stage were risk factors for preoperative anemia in patients with colorectal cancer (P<0.05). The rate of intraoperative blood transfusion and the incidence of postoperative complications in the preoperative anemia group of patients with colorectal cancer were higher than those in the non-anemia group (P<0.05). The postoperative hospital stay in the preoperative anemia group of patients with colon cancer was longer than that in the non-anemia group (P<0.05).ConclusionsThe incidence of perioperative anemia in patients with colorectal cancer is high. Advanced age, high nutritional risk, right colon cancer, T3–4 stage, and distant metastasis were the risk factors of preoperative anemia in patients with colorectal cancer. Preoperative anemia can increase the demand for intraoperative blood transfusion and the incidence of postoperative complications in patients with colorectal cancer, and prolong postoperative hospital stay of colon cancer patients.
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.
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 observe the effect of mild anemia on prognosis of hyperplastic diabetic retinopathy (PDR) treated by pars plana vitrectomy (PPV). MethodsA retrospective case-control study. From January 2021 to December 2022, 147 PDR patients with 147 eyes who received PPV treatment at Shenyang He Eye Hospital were included in the study. There were 147 eyes in 147 cases, 82 eyes in 82 males and 65 eyes in 65 females. Age was 25-79 (53.54±12.74) years old. A hemoglobin (Hb) of 90 to 120 g/L in men and 90 to 110 g/L in women was defined as mild anemia. According to Hb results, the patients were divided into mild anemia group and non-anemia group, with 39 cases (39 eyes) and 108 cases (108 eyes), respectively. The best corrected visual acuity (BCVA) test was performed using the international standard logarithmic visual acuity scale before and after the surgery, which was statistically converted to minimum resolved logarithmic (logMAR) visual acuity. The logMAR BCVA of the affected eye was 0.2-2.5 (1.60±0.62) before surgery. According to whether the BCVA improved by more than 3 lines 6 months after surgery, the affected eyes were divided into BCVA improved by more than 3 lines and BCVA improved by less than 3 lines, 117 eyes and 30 eyes, respectively. The patient's body mass index (BMI), BCVA at 6 months after surgery, and the occurrence of neovascular glaucoma (NVG) and recurrence of vitreous hemorrhage (RVH) were recorded. Independent sample t test was used for comparison between groups. Multivariate logistic regression analysis was performed to analyze the influencing factors of increased BCVA ≥3 rows after surgery. ResultsSix months after surgery, the logMAR BCVA of patients in mild anemia group and non-anemia group were 0.97±0.87 and 0.68±0.63, respectively. BCVA increased ≥3 in 26 (66.7%, 26/39) and 91 (84.3%, 91/108) eyes, respectively. logMAR BCVA (t=2.234) and BCVA increased by ≥3 rows of eyes (χ2=5.460) between the two groups, the differences were statistically significant (P=0.027, 0.019). Logistic regression analysis showed that baseline logMAR BCVA [odds ratio (OR) =4.291, 95% confidence interval (CI) 1.918-9.600, P＜0.001)], BMI (OR=1.248, 95%CI 1.057-1.472, P=0.009), the number of retinal laser photocoagulation during surgery (OR=1.001, 95%CI 1.000-1.002, P=0.038), mild anemia (OR=0.360, 95%CI 0.131-0.993, P=0.048), postoperative NVG (OR=0.156, 95%CI 0.033-0.726, P=0.018) and RVH (OR=0.264, 95%CI 0.086-0.808, P=0.020) were independent factors for BCVA improvement ≥3 lines after PPV. ConclusionsMild anemia has a certain effect on BCVA improvement after PPV of PDR. Mild anemia, post-operative NVG and RVH were independent risk factors for increasing BCVA ≥3 lines after PPV in PDR patients.
Objective To investigate the diagnostic value of the series parameters of reticulocyte in children with different types of anemia. Methods From January to August 2015, the reticulocyte parameters of 150 children with different types of anemia treated in the People’s Hospital of Dujiangyan were retrospectively analyzed. Another 150 healthy children aged 1-10 years examined in the same hospital at the same period were as the control group. Mindray BC-6900 automatic blood cell analyzer and suited reagent were used to determine the absolute value of reticulocyte (RET#), percentage of reticulocyte (RET%), immature reticulocyte ratio (IRF), low fluorescent intensity reticulocyte percentage (LFR%), moderate fluorescent intensity reticulocyte percentage (MFR%), and height fluorescent intensity reticulocyte percentage (HFR%). The data were statistically analyzed. Results Compared with the control group, RET%, RET# and IRF results in iron deficiency anemia group, hemolytic anemia group, aplastic anemia group, recent hemorrhagic anemia group, renal anemia group, leukemia and chemotherapy group had statistical difference (P<0.05). Compared with the control group, LFR%, MFR%, HFR% results in hemolytic anemia group and aplastic anemia group had statistical difference (P<0.05). LFR%, MFR% and HFR% results of other types of anemia had no statistical differences (P>0.05). Conclusion The series parameters of the reticulocyte, having an important reference value, can be used in the diagnosis of children with different types of anemia as a reference index, early diagnosis and early treatment of children with different anemia, which also can be used as a method to diagnose different types of anemia.
Objective To investigate the iron deficiency (ID) in children with congenital heart disease (CHD) and find high risk factors of ID. Methods The clinical data of 227 pediatric patients with CHD from February to June 2016 were retrospectively analyzed. The incidence of ID according to the result of iron metabolism examination (serum ferritin <12 μg/L as the diagnostic criteria) was investigated. According to their basic CHD types, patients were divided into a cyanotic group and an acyanotic group. We tried to find the high risk factors of ID in those pediatric CHD patients by comparing their age, gender, growth condition and blood routine test results. Results There were 19.8% pediatric CHD patients complicated by ID. The incidence of ID in the cyanotic patients was higher than that in the acyanotic patients (31.0% vs. 17.3%, P=0.045). In both groups, ID patients presented the characteristics of younger age, higher anemia rate, lower mean corpuscular volume (MCV), lower mean corpuscular hemoglobin (MCH), lower mean corpuscular-hemoglobin concentration (MCHC) and longer red blood cell distribution width (RDW). Conclusion Cyanosis, younger age (infant), anemia, decreased MCV, decreased MCH, decreased MCHC and increased RDW are high risk factors of ID in CHD children.
ObjectiveTo systematically review the pharmacoeconomics of high-dose intravenous iron ferric carboxymaltose in the treatment of patients with iron deficiency anemia. MethodsPharmacoeconomic studies of ferric carboxymaltose in the treatment of patients with iron deficiency anemia were searched in PubMed, The Cochrane Library, York University CRD, Web of Science, EBSCO, CNKI, WanFang Data and VIP databases, and relevant health technology assessment websites from inception to September 30th, 2021. A descriptive analysis was performed after two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. ResultsA total of 11 studies were included, most of them compared the health economics of ferric carboxymaltose with other therapies from a hospital perspective. The main costs included in these studies were costs for iron, infusion, blood transfusion, EPO, hospitalization, and transportation, as well as productivity cost. The ferric carboxymaltose was presumed to be more economical than other intravenous irons. ConclusionIt is suggested that the ferric carboxymaltose be considered in more clinical settings to improve the ischemic condition of patients with iron deficiency anemia, so as to promote the rational utilization of medical resources.
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.
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.
【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.
