Abstract
BACKGROUND AND AIMS Carvedilol reduces rates of variceal bleeding and rebleeding by lowering portal pressure. However, an associated pleiotropic survival benefit has been proposed. We aimed to assess long-term survival in a cohort of patients previously randomised to receive either carvedilol or endoscopic band ligation (EBL) following oesophageal variceal bleeding (OVB). METHODS The index study randomised 64 cirrhotic patients with OVB between 2006 and 2011 to receive either carvedilol or EBL. Follow-up was undertaken to April 2020 by review of electronic patient records. The primary outcome was survival. Other outcomes including variceal rebleeding and liver decompensation events were compared. RESULTS 26 out of 33 participants received carvedilol in the follow-up period and 28 out of 31 attended regular EBL sessions. The median number of follow-up days for all patients recruited was 1459 (SE = 281.74). On the intention to treat analysis, there was a trend towards improved survival in the carvedilol group (p = 0.09). On per-protocol analysis, carvedilol use was associated with improved long-term survival (p = 0.005, HR 3.083, 95% CI 1.397-6.809), fewer liver-related deaths (0% vs 22.57%, p = 0.013, OR ∞, 95%CI 1.565-∞) and fewer admissions with decompensated liver disease (12% vs 64.29%, p = 0.0002, OR 13.2, 95% CI 3.026-47.23) compared to the EBL group. There was no statistically significant difference in variceal rebleeding rates. CONCLUSION Following OVB in cirrhotic patients, carvedilol use is associated with survival benefit, fewer liver-related deaths and fewer hospital admissions with decompensated liver disease. Further studies are needed to validate this finding.

Abstract
Bleeding is known to influence the prognosis in patients with acute coronary syndromes. In this predefined secondary outcome analysis of the Very EaRly vs Deferred Invasive evaluation using Computerized Tomography (VERDICT) trial, we investigated whether a very early invasive coronary angiography (ICA), compared with one performed within 48 to 72 hours (standard care), was associated with fewer serious bleedings. Furthermore, we tested the association between demographic data including GRACE score and serious bleedings as well as bleedings and mortality. In the 2,147 patients included in the main study, bleedings within 30 days of admission were assessed based on Thrombolysis In Myocardial Infarction and Bleeding Academic Research Consortium criteria. Differences were calculated by cumulative incidence methods and Grays test. Variables associated with bleeding and mortality were estimated by Cox proportional hazard models. Serious (Bleeding Academic Research Consortium 3abc) bleeding rates were low (15 [1.4%, standard] vs 12 [1.2%, early], p = 0.56). There were no fatal bleedings or serious bleedings before ICA in either group. By multivariate analysis, there was no difference in bleedings between the 2 groups. Female gender (hazard ratio [HR] 2.7, 95% confidence interval [CI] 1.2 to 6.4; p = 0.02), anemia (HR 7.0, 95% CI 2.8 to 17.0; p <0.001), and increasing blood pressure (HR 1.3, 95% CI 1.1 to 1.5; p = 0.01) were individually associated with serious bleeding, whereas GRACE score >140 was not (HR 1.03, 95% CI 0.4 to 2.9; p = 0.96). In conclusion, serious bleedings were few, and there were none before ICA in either group. A very early invasive strategy did not reduce serious bleedings within 30 days, which was associated with female gender, increasing blood pressure, and anemia.

IV Sodium Ferric Gluconate Complex in Patients with Iron Deficiency hospitalized due to Acute Heart Failure- Investigator initiated, Randomized controlled trial
Marcusohn E, Borreda I, Hellman Y, Habib M, Bahouth F, Epstein D, Zukermann R
Journal of cardiovascular pharmacology. 2022
Abstract
Heart failure (HF) patients with iron deficiency (ID) have worse NYHA class and are at a higher risk of recurrent hospitalizations. Intravenous (IV) iron has been shown to improve exercise ability and reduce hospitalizations. IV Sodium Ferric Gluconate Complex (SFGC) has been found to be safe and affordable but has not been studied in this population in a randomized trial. This was prospective, single-blind, investigator-initiated, randomized controlled trial. Patients admitted for acute heart failure with ID were randomly assigned 1:1 to receive IV SFGC on top of optimal medical treatment. The primary outcome was the change in 6-minute walk test (6MWT) from baseline to 3 and 6 months. Between September 2019 and May 2021, 34 patients were randomized. 19 patients (55%) were randomized to the treatment arm receiving 125 mg of IV SFGC per day for 3 to 5 days . COVID-19 was a major barrier to the implementation of the study follow-up protocol, which caused the study to end early. Both groups of patients had similar clinical characteristics, comorbidities, median LVEF, and rate of death and readmissions due to HF. A higher level of NT-proBNP was observed in patients treated with IV iron (7902 pg/ml vs 3158, p=0.04). There was no difference in 6MWT change between groups at 3 months (improvement of 21.6 vs 24.1 meters), or 6 months (-5 meters vs. 46 meters). In conclusion, IV SFGC treated patients had comparable 6-minute walk at 3 and 6 months despite suffering from more severe HF with higher baseline NT-Pro BNP. (NCT04063033).

European journal of heart failure. 2022
Abstract
AIM: Intravenous ferric carboxymaltose (FCM) has been shown to improve overall quality of life in iron-deficient heart failure with reduced ejection fraction (HFrEF) patients at a trial population level. This FAIR-HF and CONFIRM-HF pooled analysis explored the likelihood of individual improvement or deterioration in Kansas City Cardiomyopathy Questionnaire (KCCQ) domains with FCM vs placebo and evaluated the stability of this response over time. METHODS Changes vs baseline in KCCQ overall summary score (OSS), clinical summary score (CSS) and total symptom score (TSS) were assessed at weeks 12 and 24 in FCM and placebo groups . Mean between-group differences were estimated and individual responder analyses and analyses of response stability were performed. RESULTS Overall, 760 (FCM: 454) patients were studied. At week 12, the mean improvement in KCCQ OSS was 10.6 points with FCM vs 4.8 points with placebo (least-square mean difference [95% confidence interval (CI)]: 4.36 [2.14;6.59] points). A higher proportion of patients on FCM vs placebo experienced a KCCQ OSS improvement of ≥5 (58.3% vs 43.5%; odds ratio [95% CI]: 1.81 [1.30;2.51]), ≥10 (42.4% vs 29.3%; 1.73 [1.23;2.43]) or ≥15 (32.1% vs 22.6%; 1.46 [1.02;2.11]) points. Differences were similar at week 24 and for CSS and TSS domains. Of FCM patients with a ≥5-, ≥10- or ≥15-point improvement in KCCQ OSS at week 12, >75% sustained this improvement at week 24. CONCLUSION Treatment of iron-deficient HFrEF patients with intravenous FCM conveyed clinically relevant improvements in health status at an individual-patient level; benefits were sustained over time in most patients.

Surgical technology international. 2022;40
Abstract
We treated a small cohort of venous ulcers that were very unresponsive to standard and advanced therapies with autologous cultured bone marrow-derived mesenchymal stem cells (MSCs). This pilot clinical trial was randomized, controlled, and double-blinded. Subjects were treated with either normal saline (Group A), fibrin spray alone (Group B), or MSCs in fibrin (1 million cells/cm2 of wound bed surface) (Group C). The control and test materials were applied to the wound using a double-barreled syringe with thrombin and fibrinogen (with or without MSCs) in each barrel, or saline alone in both barrels. The MSCs were separated, cultured in vitro, and expanded in a dedicated Good Manufacturing Practice (GMP) facility from 30-50 ml of bone marrow aspirate obtained from the iliac crest in Group C subjects. To ensure that the study remained controlled and blinded, subjects who were randomized to one of the two control arms (saline or fibrin) underwent sham bone marrow aspiration performed by a hematologist who anesthetized the iliac crest area down to and pushing against the periosteum, but without penetrating the bone marrow. Therefore, both the clinician who evaluated wound progress and the study subjects had no knowledge of whether bone aspiration was actually performed and what treatment had been applied to the wound. The study was performed after full FDA investigational new drug (IND) approval. The primary endpoint was the rate of healing (wound closure as linear healing from the wound margins in cm/week), as measured by the Gilman equation. One-way ANOVA was used to calculate the statistical significance of differences between the mean healing rates of each of the 3 treatment groups every 4 weeks and over the 24 weeks of treatment. Overall, treatment with MSCs accelerated the healing rate by about 10-fold compared to those in the saline and fibrin control groups. Although the total number of patients in this pilot study was small (n=11), the statistical significance was surprisingly promising: p<0.01 and f-ratio of 15.9358. No serious adverse events were noted. This small but carefully performed prospective, controlled, randomized, and double-blinded pilot study in a rare population of totally unresponsive patients adds to previous reports showing the promise of MSCs in the treatment of chronic wounds and provides proof of principle for how to approach this type of very demanding clinical and translational research.

Vascular. 2022;:17085381221104629
Abstract
OBJECTIVES to assess the safety and efficacy of platelet-rich plasma (PRP) as adjunctive to compression therapy for post-phlebitic venous ulcers. METHODS This is a single-center randomized controlled trial on patients with persistent chronic post-phlebitic lower limb venous ulcers from March 2019 to March 2020. Patients were randomly allocated to one of two equal cohort groups. Patients group in which patients underwent combined PRP with compression therapy versus control group in which patients underwent placebo+ compression therapy alone. The primary endpoint of the study was the improvement in ulcer topographic measurement. Secondary endpoints included ulcer healing parameters, possible healing factors, reduction in pain score (VAS), and the achievement of complete healing. RESULTS Forty patients were available equally for randomization and analysis in both groups. The median number of PRP applications for every patient in the patient group was 6 (ranging from 3 to 6). There was a significant decline in the median length, width, and depth of ulcers in the patients group versus control group. Consequently, there was a significant decline of the median ulcer area, in the patient group versus control group (4 (3-9) cm(2) vs. 10 (6-14) cm(2), p = .036). Also, the median volume of the ulcers showed a significant decline in the patient group versus control group (1 (.7-3) cm(3) vs 3 (2-6) cm(3), p = .008). Complete healing was achieved in 45% of patient group. There was a significant decline in pain scores at 3- and 6 months from the therapy starting point in both groups (patient group: pre-VAS = 6.5 vs. post(3 months)-VAS = 1 vs. post(6 months)-VAS = 0.5) and (control group: pre-VAS = 6.4 vs. post(3 months)-VAS = 4.5 vs. post(6 months)-VAS = 2.2), (p < .0001 for each). On the other hand, the decline in pain scores between both groups was statistically significant in favor of the patient group, (post (3 months); PRP-VAS = 1 vs. control-VAS = 4.5, and post(6 months); PRP-VAS = 0.5 vs. control-VAS = 2.2), (p < .0001). CONCLUSION Platelet-rich plasma as an adjunct to compression therapy for chronic post-phlebitic venous ulcers is safe and effective as regards the ulcer healing and improvement of pain score. PRP may be useful adjunct in treatment of post-phlebitic venous ulcer. However, larger trials are warranted.

Evaluation of pentoxifylline and ferrous sulfate for treatment of lower limb venous ulcers
Lemos PC, Lins EM, Pinto FCM, Aguiar JLA, Appolonio F, Breno F
Jornal vascular brasileiro. 2021;20:e2020167
Abstract
BACKGROUND Venous ulcers (VU) are the most advanced stage of chronic venous disease (CVD) of the lower limbs. They are frequently associated with episodes of hemorrhage that can provoke chronic anemia (CA), delaying healing. There are no studies in the literature analyzing the prevalence of CA among patients with VU of the lower limbs and few studies have analyzed use of pentoxifylline to treat VU of the lower limbs. OBJECTIVES To evaluate the prevalence of CA in patients with lower limb VU and responses to treatment with ferrous sulfate (SF) compared with a combination of SF plus pentoxifylline as adjuvant treatment for VU of the lower limbs. METHODS A total of 67 patients with lower limb VU were recruited from a Lymphedema and Angiodysplasia Clinic at the Hospital das Clínicas, Recife, PE, Brazil. After initial clinical and laboratory assessments, patients diagnosed with CA were randomized into one of two groups: a control group, given SF (900 mg/day oral route), or a study group, treated with SF (900 mg/day oral route) and pentoxifylline (1,200 mg/day). All were reassessed after 90 days. RESULTS Twenty-seven patients (40%) had CA. After treatment, increases were observed in hemoglobin and hematocrit levels, iron kinetics had improved, and both depth and area of VU had reduced in both groups, without statistically significant differences. CONCLUSIONS A high prevalence of anemia was detected in the study population. The combination of SF and pentoxifylline was not more effective than SF alone for adjuvant treatment of VU of the lower limbs.

Abstract
IMPORTANCE The optimal transfusion strategy in patients with acute myocardial infarction and anemia is unclear. OBJECTIVE To determine whether a restrictive transfusion strategy would be clinically noninferior to a liberal strategy. DESIGN, SETTING, AND PARTICIPANTS Open-label, noninferiority, randomized trial conducted in 35 hospitals in France and Spain including 668 patients with myocardial infarction and hemoglobin level between 7 and 10 g/dL. Enrollment could be considered at any time during the index admission for myocardial infarction. The first participant was enrolled in March 2016 and the last was enrolled in September 2019. The final 30-day follow-up was accrued in November 2019. INTERVENTIONS Patients were randomly assigned to undergo a restrictive (transfusion triggered by hemoglobin ≤8; n = 342) or a liberal (transfusion triggered by hemoglobin ≤10 g/dL; n = 324) transfusion strategy. MAIN OUTCOMES AND MEASURES The primary clinical outcome was major adverse cardiovascular events (MACE; composite of all-cause death, stroke, recurrent myocardial infarction, or emergency revascularization prompted by ischemia) at 30 days. Noninferiority required that the upper bound of the 1-sided 97.5% CI for the relative risk of the primary outcome be less than 1.25. The secondary outcomes included the individual components of the primary outcome. RESULTS Among 668 patients who were randomized, 666 patients (median [interquartile range] age, 77 [69-84] years; 281 [42.2%] women) completed the 30-day follow-up, including 342 in the restrictive transfusion group (122 [35.7%] received transfusion; 342 total units of packed red blood cells transfused) and 324 in the liberal transfusion group (323 [99.7%] received transfusion; 758 total units transfused). At 30 days, MACE occurred in 36 patients (11.0% [95% CI, 7.5%-14.6%]) in the restrictive group and in 45 patients (14.0% [95% CI, 10.0%-17.9%]) in the liberal group (difference, -3.0% [95% CI, -8.4% to 2.4%]). The relative risk of the primary outcome was 0.79 (1-sided 97.5% CI, 0.00-1.19), meeting the prespecified noninferiority criterion. In the restrictive vs liberal group, all-cause death occurred in 5.6% vs 7.7% of patients, recurrent myocardial infarction occurred in 2.1% vs 3.1%, emergency revascularization prompted by ischemia occurred in 1.5% vs 1.9%, and nonfatal ischemic stroke occurred in 0.6% of patients in both groups. CONCLUSIONS AND RELEVANCE Among patients with acute myocardial infarction and anemia, a restrictive compared with a liberal transfusion strategy resulted in a noninferior rate of MACE after 30 days. However, the CI included what may be a clinically important harm. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02648113.

Abstract
AIMS: Patients with heart failure (HF) and iron deficiency experience poor health-related quality of life (HRQoL). We evaluated the impact of intravenous (IV) ferric carboxymaltose (FCM) vs. placebo on HRQoL for the AFFIRM-AHF population. METHODS AND RESULTS The baseline 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12), which was completed for 1058 (535 and 523) patients in the FCM and placebo groups, respectively, was administered prior to randomization and at Weeks 2, 4, 6, 12, 24, 36, and 52. The baseline KCCQ-12 overall summary score (OSS) mean ± standard error was 38.7 ± 0.9 (FCM group) and 37.1 ± 0.8 (placebo group); corresponding values for the clinical summary score (CSS) were 40.9 ± 0.9 and 40.1 ± 0.9. At Week 2, changes in OSS and CSS were similar for FCM and placebo. From Week 4 to Week 24, patients assigned to FCM had significantly greater improvements in OSS and CSS scores vs. placebo [adjusted mean difference (95% confidence interval, CI) at Week 4: 2.9 (0.5-5.3, P = 0.018) for OSS and 2.8 (0.3-5.3, P = 0.029) for CSS; adjusted mean difference (95% CI) at Week 24: 3.0 (0.3-5.6, P = 0.028) for OSS and 2.9 (0.2-5.6, P = 0.035) for CSS]. At Week 52, the treatment effect had attenuated but remained in favour of FCM. CONCLUSION In iron-deficient patients with HF and left ventricular ejection fraction ≤50% who had stabilized after an episode of acute HF, treatment with IV FCM, compared with placebo, results in clinically meaningful beneficial effects on HRQoL as early as 4 weeks after treatment initiation, lasting up to Week 24.

Abstract
AIMS: Iron deficiency is common in patients with heart failure (HF). In AFFIRM-AHF, ferric carboxymaltose (FCM) reduced the risk of hospitalisations for HF (HHF) and improved quality of life vs. placebo in iron-deficient patients with a recent episode of acute HF. The objective of this study was to estimate the cost-effectiveness of FCM compared with placebo in iron-deficient patients with left ventricular ejection fraction <50%, stabilised after an episode of acute HF, using data from the AFFIRM-AHF trial from Italian, UK, US and Swiss payer perspectives. METHODS AND RESULTS A lifetime Markov model was built to characterise outcomes in patients according to the AFFIRM-AHF trial. Health states were defined using the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Subsequent HHF were incorporated using a negative binomial regression model with cardiovascular and all-cause mortality incorporated via parametric survival analysis. Direct healthcare costs (2020 GBP/USD/EUR/CHF) and utility values were sourced from published literature and AFFIRM-AHF. Modelled outcomes indicated that treatment with FCM was dominant (cost saving with additional health gains) in the UK, USA and Switzerland, and highly cost-effective in Italy [incremental cost-effectiveness ratio (ICER) EUR 1269 per quality-adjusted life-year (QALY)]. Results were driven by reduced costs for HHF events combined with QALY gains of 0.43-0.44, attributable to increased time in higher KCCQ states (representing better functional outcomes). Sensitivity and subgroup analyses demonstrated data robustness, with the ICER remaining dominant or highly cost-effective under a wide range of scenarios, including increasing treatment costs and various patient subgroups, despite a moderate increase in costs for de novo HF and smaller QALY gains for ischaemic aetiology. CONCLUSION Ferric carboxymaltose is estimated to be a highly cost-effective treatment across countries (Italy, UK, USA and Switzerland) representing different healthcare systems.
