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.
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.
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 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 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.
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.
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.
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.
Objective To investigate the effectiveness of recombinant human erythropoietin (rHuEPO) combined with iron in treatment of anemia in elderly patients with intertrochanteric fractures during perioperative period. Methods A clinical data of 71 patients with intertrochanteric fractures met the inclusion criteria between April 2016 and October 2017 was retrospectively analyzed. All patients were treated with closed reduction and proximal femoral intramedullary nail fixation. Thirty-one patients were treated with rHuEPO and iron before operation as trial group, and 40 patients were not treated with rHuEPO and iron as control group. There was no significant difference in gender, age, body mass index, cause of injury, fracture side and classification, American Society of Anesthesiologists (ASA) classification, combined medical diseases, time from fracture to admission, preoperative hospital stay, and operation time between the two groups (P>0.05).The hemoglobin levels before operation and at 1, 3, and 7 days after operation, number of blood transfusion, blood transfusion rate, blood transfusion volume, postoperative hospital stay, complications were recorded and compared. Results After operation, 8 patients (25.8%) in trial group and 22 patients (55.0%) in control group received blood transfusion; the blood transfusion volume was (1.96±0.85) units in trial group and (3.19±1.61) units in control group. There were significant differences in blood transfusion rate and volume between the two groups (P<0.05). There was no significant difference in preoperative hemoglobin level between the two groups (P>0.05). The postoperative hemoglobin level was higher in trial group than in control group, and the difference between the two groups was significant at 7 days (P<0.05). The postoperative hospital stay was (6.16±3.97) days in trial group and (9.25±4.47) days in control group, showing significant difference between the two groups (P<0.05). There were 8 patients (25.8%) with pulmonary infection in trial group and 14 (35.0%) in control group after operation; 6 patients (19.4%) with deep venous thrombosis in trial group and 8 (20.0%) in control group. There was no significant difference in the incidences of complications between the two groups (P>0.05). All patients were discharged from hospital normally, and no one died during hospitalization. Conclusion The application of rHuEPO combined with iron before operation in elderly patients with intertrochanteric fractures can rapidly increase the hemoglobin level after operation, shorten the hospital stay, and do not increase the risk of deep venous thrombosis after operation.
Objective To asses the clinical effectiveness and safety of combined treatment with antilymphocyte globulin (ATG) and cyclosporine A (CSA) versus antilymphocyte globulin alone in patients with aplastic anemia (AA). Methods Randomized controlled trials (RCTs) were identified from MEDLINE (1966 to September 2007), EMBASE (1984 to September 2007), The Cochrane Library (issue 4, 2007) and CBM-disc (1978 to September 2007). The references of eligible studies were hand searched. RCTs involving ATG and CSA in the treatment of AA were included. Data were evaluated and extracted by two reviewers independently with designed extraction form. The Cochrane Collaboration’ s RevMan 4.2.10 software was used for data analyses. Results Two RCTs involving 160 patients were included. Two studies showed that the effective rate in the ATG+CSA group was significantly higher than that in the ATG group (Plt;0.0001). Two studies indicated that the survival rate in the ATG+CSA group was improved compared with the ATG group (P=0.0002). One study reported adverse effect. The ATG group caused more fever and serum diseases compared with the ATG+CSA group, but the ATG+CSA group had a higher incidence of hepatotoxicity. Conclusion Treatment with ATG+CSA for aplastic anemia has higher effective rate and survival rate than ATG alone. More trials of high quality are required.
