Circulation. Cardiovascular Interventions. 2023;16(2):e012781
Abstract
BACKGROUND The optimal duration of hemostatic compression post transradial access is controversial. Longer duration increases the risk of radial artery occlusion (RAO) while shorter duration increases the risk of access site bleeding or hematoma. As such, a target of 2 hours is typically used. Whether a shorter or longer duration is better is not known. METHODS A PubMed, EMBASE, and clinicaltrials.gov databases were searched for randomized clinical trials of different duration (<90 minutes, 90 minutes, 2 hours, and 2-4 hours) of hemostasis banding. The efficacy outcome was RAO, primary safety outcome was access site hematoma, and secondary safety outcome was access site rebleeding. Primary analysis compared the effect of various duration in reference to the 2 hours duration using a mixed treatment comparison meta-analysis. RESULTS Of the 10 randomized clinical trials included with 4911 patients, when compared to the 2-hour reference duration, there was a significantly higher risk of access site hematoma with 90 minutes (odds ratio, 2.39 [95% CI, 1.40-4.06]) and <90 minutes (odds ratio, 3.61 [95% CI, 1.79-7.29]) but not with the 2 to 4 hours duration. When compared with the 2-hour reference, there was no significant difference in access site rebleeding or RAO with shorter or longer duration but the point estimates favored longer duration for access site rebleeding and shorter duration for RAO. Duration of <90 minutes and 90 minutes ranked 1 and duration of 2 hours ranked 2 as the most efficacious duration whereas duration of 2 hours ranked 1 and 2 to 4 hours ranked 2 as the safest duration. CONCLUSIONS In patients undergoing transradial access for coronary angiography or intervention, a hemostasis duration of 2 hours offers the best balance for efficacy (prevention of RAO) and safety (prevention of access site hematoma/rebleeding).

Clinical and experimental nephrology. 2023
Abstract
BACKGROUND Erythropoiesis-stimulating agents (ESAs) are the standard treatment for patients with renal anemia to increase hemoglobin (Hb) levels and reduce the need for blood transfusions. However, treatments targeting high Hb levels require high doses of ESAs administered intravenously, which is associated with an elevated risk of adverse cardiovascular events. Furthermore, there have been some problems such as hemoglobin variability and low achievement of target hemoglobin due to the shorter half-lives of ESAs. Consequently, erythropoietin-promoting medications, such as hypoxia-inducible factor-prolyl hydroxylase (HIF-PH) inhibitors, have been developed. This study aimed to evaluate changes in the Treatment Satisfaction Questionnaire for Medicine version II (TSQM-II) domain scores relative to baseline in each trial, to assess patient satisfaction with molidustat versus darbepoetin alfa. METHODS This post-hoc analysis of two clinical trials compared treatment satisfaction with an HIF-PH inhibitor, molidustat, versus a standard ESA, darbepoetin alfa, as part of therapy in patients with non-dialysis chronic kidney disease (CKD) and renal anemia. RESULTS Exploratory outcome data using the TSQM-II showed that both arms in both trials had enhanced treatment satisfaction over the course of the study period, as well as improvements in most TSQM-II domains at week 24 of treatment. Molidustat was associated with convenience domain scores at multiple time points depending on the trial. More patients were highly satisfied with the convenience of molidustat than that of darbepoetin alfa. Patients treated with molidustat had increased global satisfaction domain scores compared with those treated with darbepoetin alfa; however, the differences in global satisfaction domain scores were not significant. CONCLUSION These patient-reported satisfaction outcomes support the use of molidustat as a patient-centered treatment option for CKD-related anemia.

Abstract
BACKGROUND Intracerebral hemorrhage (ICH) is a stroke with a high morbidity and mortality rate. Deferoxamine (DFX) is thought to be effective in treating Intracerebral Hemorrhage. In our study, we performed a meta-analysis to evaluate the treatment effects of DFX. METHODS We systematically searched PubMed, Embase, Web of Science, the Cochrane Central Register of Controlled Trials, and Chinese Biomedical Literature Database in Jan 2022 for studies on DFX for ICH patients. Outcome measures included relative hematoma volume, relative edema volume, good neurological functional outcome and adverse events. Odds risk (OR) and weighted mean difference (WMD) were used to evaluate clinical outcomes. RESULTS After searching 636 articles, 4 RCTs, 2 NRCTs, and 1cohort study were included. We found that DFX was effective in hematoma absorption on day 7 after onset, but the difference was not significant on day 14. DFX could suppress edema expansion on days 3, 7, and 14 after onset. DFX did not contribute to better outcomes after 3 and 6 months when used the modified Rankin Scale and the Glasgow Outcome Scale to evaluate neurological prognosis. The pooled results showed no statistically significant difference in Serious adverse events between the experimental and control groups. CONCLUSIONS DFX could limit edema expansion on days 3, 7, and 14 after commencement and facilitate hematoma absorption at week 1 without significantly increasing the risk of adverse events, but it did not improve neurological prognosis.

Intravenous ferric carboxymaltose versus oral ferrous sulfate replacement in elderly patients after acute non-variceal gastrointestinal bleeding (FIERCE): protocol of a multicentre, open-label, randomised controlled trial
Teutsch, B., Váncsa, S., Farkas, N., Szakács, Z., Vörhendi, N., Boros, E., Szabó, I., Hágendorn, R., Alizadeh, H., Hegyi, P., et al
BMJ open. 2023;13(3):e063554
Abstract
INTRODUCTION Acute gastrointestinal bleeding (GIB) is a life-threatening emergency with a critical economic burden. As a result of bleeding, anaemia often requires intravenous or oral iron supplementation. Elderly patients are even more prone to untoward outcomes after hospital discharge if iron supplementation is inefficient. There is a gap in current guidelines on which supplementation route clinicians should choose. We aim to investigate the effect of one dose of intravenous iron therapy versus 3-month oral iron administration on anaemia in an elderly population. METHODS AND ANALYSIS The FIERCE study is an open-label, randomised controlled, two-armed trial. At least 48 hours after the acute non-variceal GIB treatment, patients will be recruited in participating centres. A random sequence generator will allocate the participants to group A (intravenous ferric carboxymaltose, 1000 mg) or group B (oral ferrous sulfate (FS), ca. 200 mg every day) with an allocation ratio of 1:1 on the day of the planned discharge from the hospital. Randomisation will be stratified for participating centres and the need for transfusion within the same hospitalisation before recruitment to the trial. Quality of life assessment, functional measurement and laboratory tests will be performed at baseline, 1 and 3 months±7 days after enrolment to the trial. The primary endpoint is a composite endpoint, including all-cause mortality, anaemia-associated unplanned emergency visit and anaemia-associated unplanned hospital admission within 3 months of enrolment in the trial. ETHICS AND DISSEMINATION The study has been approved by the relevant organisation, the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (46395-5/2021/EÜIG). We will disseminate our results to the medical community and will publish our results in peer-reviewed journals. TRIAL REGISTRATION The trial has been registered at ClinicalTrials.gov (NCT05060731).

Drug research. 2023
Abstract
PURPOSE This study was conducted to evaluate whether the efficacy and safety profile of recombinant human erythropoietin (rhEPO) manufactured by Daewoong Pharmaceutical Co., Ltd was similar to biological products approved by the drug safety regulatory authority. PATIENTS AND METHODS It was an open-label, randomized, comparative, parallel, multi-center study in hemodialysis patients with anemia. The reference product at an individualized dose 3 times a week was given in 4-8 weeks of titration period and hemoglobin (Hb) level was controlled to reach the range of 10-12 g/dL. Then, the subjects were randomly administered with reference or test product with the same dose regimen. The primary endpoints were to demonstrate the Hb level change between baseline and evaluation period in both treatment groups, while the secondary endpoints were the mean change in weekly dosage per kg body weight and the instability rate of Hb level during maintenance and evaluation period. The safety was evaluated based on the adverse events incidence. RESULTS There was no statistical difference in the change of Hb between test and reference (0.14 g/dL and 0.75 g/dL respectively, with p>0.05), also for the mean changes of weekly dosage between groups (1091.40 IU and 570.15 IU respectively, with p>0.05). The instability rate of Hb in both test and reference was not statistically significantly different as well (26 and 15% respectively, with p>0.05). CONCLUSION This study proves that the efficacy indicated by the change instability of Hb and safety indicated by adverse event incidence of Epodion and the reference product on chronic kidney disease were similar.

Reinhold, J., Burra, V., Corballis, N., Tsampasian, V., Matthews, G., Papadopoulou, C., Vassiliou, V. S.
Journal of Cardiovascular Development and Disease. 2023;10(3)
Abstract
(1) Background: Iron deficiency (ID) is an important adverse prognostic marker in patients with heart failure (HF); however, it is unclear whether intravenous iron replacement reduces cardiovascular mortality in this patient group. Here, we estimate the effect of intravenous iron replacement therapy on hard clinical outcomes following the publication of IRONMAN, the largest trial in this field. (2) Methods: In this systematic review and meta-analysis, prospectively registered with PROSPERO and reported according to PRISMA guidelines, we searched PubMed and Embase for randomized controlled trials investigating intravenous iron replacement in patients with HF and co-existing ID. The primary outcome was cardiovascular mortality and secondary outcomes were all-cause mortality, hospitalizations for HF and a combination of the primary outcome and hospitalizations for HF. (3) Results: A total of 1671 items were identified and after removal of duplicates we screened titles and abstracts of 1202 records. Some 31 studies were identified for full-text review and 12 studies were included in the final review. The odds ratio (OR) for cardiovascular death using a random effects model was 0.85 (95% CI 0.69 to 1.04) and for all-cause mortality it was 0.83 (95% CI 0.59 to 1.15). There was a significant reduction in hospitalizations for HF (OR 0.49, 95% CI 0.35 to 0.69) and the combination of hospitalizations for HF and cardiovascular death (OR 0.65, 95% CI 0.5 to 0.85). (4) Conclusions: This review supports the use of IV iron replacement reducing hospitalization rates for HF, however more research is required to determine the effect on cardiovascular mortality and to identify the patient population most likely to benefit.

Abstract
INTRODUCTION This study was conducted to elucidate the safety of roxadustat, an oral medication, in patients with non-dialysis-dependent (NDD) or incident dialysis dialysis-dependent (ID-DD) chronic kidney disease (CKD). METHODS Safety results from four phase 3, randomized, open-label studies comparing roxadustat to an erythropoiesis-stimulating agent (ESA) in men and women with NDD or ID-DD CKD with anemia were pooled and evaluated. Endpoints were time to major adverse cardiovascular event (MACE; myocardial infarction, stroke, and all-cause mortality) and MACE+ (MACE plus congestive heart failure or unstable angina requiring hospitalization), all-cause mortality, and treatment-emergent adverse events (TEAEs). MACE and MACE+ were evaluated for non-inferiority at 1.8- and 1.3-margins using hazard ratios (HRs) and 95% confidence intervals (CIs). TEAEs were descriptively summarized. RESULTS In total, 2142 patients were evaluated (1083 roxadustat; 1059 ESA). Roxadustat was comparable to ESA for risk of MACE (HR 0.79, 95% CI 0.61-1.02), MACE+ (HR 0.78, 95% CI 0.62-0.98), and all-cause mortality (HR 0.78, 95% CI 0.57-1.05). TEAEs were comparable between roxadustat and ESA groups, including any TEAE [incidence rate per 100 (IR/100) patient-exposure years 56.1 vs. 53.5], TEAEs leading to study drug discontinuation (IR/100 patient-exposure years 6.7 vs. 5.1), and TEAEs leading to death (IR/100 patient-exposure years 6.9 vs. 7.4). CONCLUSION There was no evidence of increased risk of cardiovascular events or mortality with roxadustat compared with ESA in patients with anemia who have NDD or ID-DD CKD. Although TEAEs occurred commonly in both the roxadustat and ESA groups, patients infrequently discontinued the study drug because of an adverse event.

Abstract
INTRODUCTION Blue Rubber Bleb Nevus Syndrome (BRBNS) is a rare challenging cause of gastrointestinal bleeding. We performed a systematic review of case reports and case series on BRBNS to gather information on the treatment options currently available. METHOD All studies reporting a case of BRBNS in humans were evaluated. Papers were ruled out whether CARE criteria and explanations on patient's selection, ascertainment, causality, and reporting were not respected or identified. PROSPERO 2021 CRD 42021286982. RESULTS BRNBS was treated in 106 cases from 76 reports. 57.5% of the population was under 18 years old, and up to 50% of the cases reported a previous treatment. Clinical success was achieved in 98 patients (92.4%). Three main types of interventions were identified: systemic drug therapy, endoscopy and surgery. After BRBNS recurrence or previous therapy failure, systemic drug therapy emerged as a preferred second-line treatment over endoscopy (p=0.01), but with a higher rate of reported adverse events when compared with surgery and endoscopy (p < 0.001). Endoscopic treatment was associated with a higher number of required sessions to achieve complete eradication when compared with surgery (p < 0.001). No differences between the three main areas were found in the overall follow-up time (p=0.19) and in the recurrence rate (p=0.45). CONCLUSION Endoscopy, surgery and systemic drug therapy are feasible treatment options for BRBNS. Systemic drug therapy was the favourite second-line treatment after endoscopic failure or recurrence of BRBNS, but adverse events were more frequently reported.

Abstract
BACKGROUND It has been shown that ferric carboxymaltose (FCM) improves symptoms and quality of life in iron-deficient patients with heart failure (HF). AIM: We aimed to systematically review studies conducted on the cost-effectiveness of FCM compared to placebo in iron-deficient patients with HF. METHOD We searched PubMed, EMBASE, Scopus, and Web of Science to find the relevant studies. After removing duplicates, two authors independently evaluated the titles, abstracts, and full texts. We included studies that investigated the full economic evaluations of FCM in HF patients with iron deficiency (cost-effectiveness analysis, cost-utility analysis, and cost-benefit analysis) and used the CHEERS tool to evaluate the quality of the studies. RESULTS Seven studies were included which evaluated the economic analysis of treatments with FCM in iron-deficient patients with HF. The CHEERS scores for most of the studies (n = 6) were 0.77 or higher (very good quality). The lowest incremental cost-effectiveness ratio (ICER) per quality-adjusted life years (QALY) of FCM ($1801.96) was from Italy, and the highest ICER per QALY of FCM ($25,981.28) South Korea. Results of the studies showed that FCM, compared to placebo, was cost-effective in iron-deficient patients with HF. CONCLUSION FCM is a cost-effective treatment for iron-deficient patients with HF. Considering the fact that all the included studies in the present systematic review took place in high-income countries, we recommend further studies investigating the cost-effectiveness of FCM in low- and middle-income countries.

Tranexamic acid for gastrointestinal bleeding: can a reduction in the risk of death be discounted? A systematic review and meta-analysis of individual patient data from 64 724 bleeding patients
Ker, K., Mansukhani, R., Shakur-Still, H., Arribas, M., Beaumont, D., Roberts, I.
BMJ open. 2023;13(2):e059982
Abstract
OBJECTIVES HALT-IT was an international, randomised trial which assessed the effects of tranexamic acid (TXA) in 12 009 patients with gastrointestinal (GI) bleeding. The results found no evidence that TXA reduces death. It is widely accepted that results of trials should be interpreted in the context of other relevant evidence. We conducted a systematic review and individual patient data (IPD) meta-analysis to assess if the results of HALT-IT are compatible with evidence for TXA in other bleeding conditions. DESIGN Systematic review and IPD meta-analysis of randomised trials involving ≥5000 patients assessing TXA for bleeding. We searched our Antifibrinolytics Trials Register on 1 November 2022. Two authors extracted data and assessed risk of bias. DATA SYNTHESIS We used a one-stage model to analyse IPD in a regression model stratified by trial. We assessed heterogeneity of the effect of TXA on death within 24 hours and vascular occlusive events (VOEs). RESULTS We included IPD for 64 724 patients from four trials involving patients with traumatic, obstetric and GI bleeding. Risk of bias was low. There was no evidence for heterogeneity between trials for the effect of TXA on death or for the effect of TXA on VOEs. TXA reduced the odds of death by 16% (OR=0.84, 95% CI: 0.78 to 0.91, p<0.0001; p-heterogeneity=0.40). In patients treated within 3 hours of bleeding onset, TXA reduced the odds of death by 20% (0.80, 0.73 to 0.88, p<0.0001; p-heterogeneity=0.16). TXA did not increase the odds of VOEs (0.94, 0.81 to 1.08, p for effect=0.36; p-heterogeneity=0.27). CONCLUSIONS There is no evidence for statistical heterogeneity between trials assessing the effect of TXA on death or VOEs in different bleeding conditions. When the HALT-IT results are considered in the context of other evidence, a reduction in the risk of death cannot be discounted. TRIAL REGISTRATION NUMBER PROSPERO CRD42019128260.Cite Now.
