Bleeding Episodes in Patients With Non-ST-Segment Elevation Acute Coronary Syndrome Undergoing Very Early Versus Standard Care Invasive Examination (from the Very EaRly vs Deferred Invasive Evaluation Using Computerised Tomography [VERDICT] Trial)
The American journal of cardiology. 2022
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.
Transfusion strategies in patients with acute coronary syndrome and anemia: a meta-analysis
The Egyptian heart journal : (EHJ) : official bulletin of the Egyptian Society of Cardiology. 2022;74(1):17
BACKGROUND Anemia is a known risk factor for ischemic heart disease and serves as an independent predictor of major adverse cardiovascular events (MACE) in patients with acute coronary syndrome (ACS). This meta-analysis pools data from randomized controlled trials (RCTs) to better define hemoglobin (Hb) thresholds for transfusion in this setting. RESULTS MEDLINE, EMBASE, and Cochrane databases were searched using the terms "Acute Coronary Syndrome" AND "Blood Transfusion" including their synonyms. A total of three randomized controlled trials were included. Restrictive transfusion strategy (RTS) was defined as transfusing for Hb ≤ 8 g/dl with a post-transfusion goal of 8 to 10 g/dl. Liberal transfusion strategy (LTS) was defined as Hb ≤ 10 g/dl and post-transfusion goal of at least 11 g/dl. The primary end point was 30-day mortality. Secondary outcomes included recurrent ACS events, new or worsening CHF within 30 days, and major adverse cardiac events (MACE). The primary analytic method used was random effects model. Out of 821 patients, 400 were randomized to LTS, and 421 to RTS. Mean age was 70.3 years in RTS versus 76.4 in LTS. There was no statistically significant difference for 30-day mortality in LTS compared to RTS [odds ratio (OR) 1.69; 95% CI 0.35 to 8.05]. Similarly, there was no difference in MACE (OR 0.74; 95% CI 0.21 to 2.63), CHF (OR 0.82; 95% CI 0.18 to 3.76), or the incidence of recurrent ACS (OR 1.21; 95% CI 0.49 to 2.95). CONCLUSIONS In the setting of ACS, there is no difference between LTS and RTS for the outcomes of mortality, MACE, recurrent ACS, or CHF at 30 days. Further evidence in the form of high-quality RCTs are needed to compare RTS and LTS.
Combined diffuse alveolar hemorrhage and venous thrombosis in a patient with granulomatosis with polyangiitis: Case report and systematic review of literature
Lung India : official organ of Indian Chest Society. 2022;39(1):70-73
Antineutrophil cytoplasmic antibody-associated vasculitis has associations with both thrombosis and diffuse alveolar hemorrhage (DAH). Management of patients having coexistence of both thrombotic and hemorrhagic manifestations is challenging. Thrombotic conditions require anticoagulation, which can theoretically increase the risk of bleeding and thereby worsen DAH. In this review, we highlight the management of a patient of granulomatosis with polyangiitis with DAH who developed deep vein thrombosis. A systematic review of the literature was also performed summarizing and discussing the issues pertaining to the management of such patients.
Recent Advancements in the Management of Anti-neutrophil Cytoplasmic Antibody-Associated Vasculitis: A Systematic Review
Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a rare multisystem autoimmune condition that causes inflammation of small and medium-sized blood vessels and is more commonly seen in the geriatric population. ANCA-associated vasculitis (AAV) is typically characterized as necrotizing vasculitis and includes granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). The mortality rate remains high, with especially cardiovascular disease, infections, and malignancies being the leading causes of death. Existing treatment options depend heavily on the use of glucocorticoids (GCs), often in combination with cyclophosphamide (CYC); however, as the multitude of adverse effects associated with these agents has increased, numerous studies are being conducted to reduce not only these harmful effects but also improve remission rates. Rituximab, avacopan, corticosteroids, including intravenous pulse methylprednisolone, plasma exchange, and immunological targeting are among the emerging treatments. The purpose of this review is to emphasize the pathogenesis and traditional treatment modalities and give insights into the recent advances in managing this disorder in an attempt to spare the adverse effects of conventional therapies while achieving better remission rates with combination therapies as well. The authors explored multiple databases, employing appropriate keywords, satisfying the quality appraisal, after which a total of 14 reports were included in this review. Upon overall analysis, it can be concluded that rituximab and CYC, when used in combination, provided a safer alternative to GCs while exhibiting equal, if not superior, effectiveness and results, thus, paving the way for additional in-depth research in a larger population of interest.
Beta-blockers versus placebo or no intervention for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis
The Cochrane database of systematic reviews. 2021;1:Cd011973
BACKGROUND Portal hypertension commonly accompanies advanced liver disease and often gives rise to life-threatening complications, including haemorrhage from oesophageal and gastrointestinal varices. Variceal haemorrhage commonly occurs in children with chronic liver disease or portal vein thrombosis. Therefore, prevention is important. Band ligation, beta-blockers, and sclerotherapy have been proposed as alternatives for primary prophylaxis of oesophageal variceal bleeding in children. However, primary prophylaxis is not the current standard of care in paediatric patients because it is unknown whether those treatments are of benefit or harm when used for primary prophylaxis in children and adolescents. OBJECTIVES To determine the benefits and harms of beta-blockers compared with placebo or no intervention for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, CENTRAL, PubMed, Embase, LILACS, and Science Citation Index Expanded (April 2020). We screened the reference lists of the retrieved publications and manually searched the main paediatric gastroenterology and hepatology conference (NASPGHAN and ESPGHAN) abstract books from 2008 to December 2019. We searched clinicaltrials.gov, the United States Food and Drug Administration (FDA), the European Medicines Agency (EMA), and the World Health Organization (WHO) for ongoing clinical trials. We imposed no language or document type restrictions on our search. SELECTION CRITERIA We planned to include randomised clinical trials, irrespective of blinding, language, or publication status to assess benefits and harms. We included observational studies, retrieved with the searches for randomised clinical trials, for a narrative report of harm. DATA COLLECTION AND ANALYSIS We planned to summarise data from randomised clinical trials by standard Cochrane methodologies. We planned to asses risk of bias and use GRADE to assess the certainty of evidence. Our primary outcomes were all-cause mortality, serious adverse events and liver-related morbidity, and health-related quality of life. Our secondary outcomes were oesophageal variceal bleeding and adverse events not considered serious. We planned to use intention-to-treat principle. We planned to analyse data with RevMan Analysis. MAIN RESULTS We found no randomised clinical trials that assessed beta-blockers compared with sham or no intervention for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis. We found four observational studies that reported on harms. As a systematic search for observational studies was not planned, we only listed the reported harms in a table. AUTHORS' CONCLUSIONS Randomised clinical trials assessing the benefits or harms of beta-blockers versus placebo or no intervention for primary prophylaxis of oesophageal variceal bleeding in children with chronic liver disease or portal vein thrombosis are lacking. Therefore, trials with adequate power and proper design, assessing the benefits and harms of beta-blockers versus placebo on patient-relevant clinical outcomes, such as mortality, quality of life, failure to control variceal bleeding, and adverse events are needed. Unless such trials are conducted and the results become published, we cannot make any conclusions regarding the benefits or harms of the two interventions.
Effect of iron supplementation in patients with heart failure and iron deficiency: A systematic review and meta-analysis
International journal of cardiology. Heart & vasculature. 2021;36:100871
BACKGROUND The effectiveness of oral and intravenous iron supplementation in reducing the risk of mortality and hospitalizations in HF patients with iron deficiency is not well-established. METHODS A thorough literature search was conducted across 2 electronic databases (Medline and Cochrane Central) from inception through March 2021. RCTs assessing the impact of iron supplementation on clinical outcomes in iron deficient HF patients were considered for inclusion. Primary end-points included all-cause mortality and HF hospitalization. Evaluations were reported as odds ratios (ORs) or risk ratios (RRs) with 95% confidence intervals (CI) and analysis was performed using a random effects model. I(2) index was used to assess heterogeneity. RESULTS From the 2599 articles retrieved from initial search, 10 potentially relevant studies (n = 2187 patients) were included in the final analysis. Both oral (OR: 0.93; 95% CI: 0.08-11.30; p = 0.951) and intravenous (OR: 0.97; 95% CI: 0.73-1.29; p = 0.840) iron supplementation did not significantly reduce all-cause mortality. However, intravenous iron supplementation significantly decreased the rates of overall (OR: 0.52; 95% CI: 0.33-0.81; p = 0.004) and HF (OR: 0.42; 95% CI: 0.22-0.80; p = 0.009) hospitalizations. In addition, intravenous ferric carboxymaltose therapy significantly reduced the time to first HF hospitalization or cardiovascular mortality (RR = 0.70; 95% CI = 0.50-1.00; p = 0.048), but had no effect on time to first cardiovascular death (RR: 0.94; 95% CI: 0.70-1.25; p = 0.655). CONCLUSION Oral or intravenous iron supplementation did not reduce mortality in iron deficient HF patients. However, intravenous iron supplementation was associated with a significant decrease in overall and HF hospitalizations.
Evaluation of pentoxifylline and ferrous sulfate for treatment of lower limb venous ulcers
Jornal vascular brasileiro. 2021;20:e2020167
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.
Effect of a Restrictive vs Liberal Blood Transfusion Strategy on Major Cardiovascular Events Among Patients With Acute Myocardial Infarction and Anemia: The REALITY Randomized Clinical Trial
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.
Patients with myocardial infarction enrolled in the REALITY trial (n= 668).
Restrictive transfusion strategy, haemoglobin <8 g/dL (n= 342).
Liberal transfusion strategy, haemoglobin <10 g/dL (n = 324).
Among the patients in the restrictive transfusion group, 122 (35.7%) received transfusion, compared to 323 (99.7%) patients in the liberal transfusion group. At 30 days, major adverse cardiovascular events occurred in 36 patients (11.0%) in the restrictive group and in 45 patients (14.0%) in the liberal group. 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.
Granulomatosis With Polyangiitis and Microscopic Polyangiitis: A Systematic Review and Meta-Analysis of Benefits and Harms of Common Treatments
ACR open rheumatology. 2021
OBJECTIVE The aim of this systemic review is to compare different treatments for patients with granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) to inform evidence-based recommendations for the American College of Rheumatology (ACR)/Vasculitis Foundation (VF) Vasculitis Management Guidelines. METHODS A systemic review was conducted by searching articles in English using OVID Medline, PubMed, Embase, and the Cochrane Library. Articles were screened for suitability in addressing PICO questions, with studies presenting the highest level of evidence given preference. RESULTS A total of 729 full-text articles addressing GPA and MPA PICO questions were reviewed. For remission induction, rituximab was shown to be noninferior to cyclophosphamide (CYC) (odds ratio [OR]: 1.55, moderate certainty of evidence). The addition of plasma exchange to induction therapy in severe disease did not improve the composite end point of death or end stage renal disease (hazard ratio [HR]: 0.86 [95% confidence interval CI: 0.65, 1.13], moderate certainty of evidence). In nonsevere disease, methotrexate was noninferior to CYC for induction of remission (remission at 6 months of 90% vs. 94%). For maintenance of remission, methotrexate and azathioprine showed no difference in the risk of relapse over a mean follow-up of 29 months (HR: 0.92, [95% CI: 0.52, 1.65]low certainty of evidence). As maintenance therapy, rituximab was superior to a tapering azathioprine strategy in major relapse-free survival at 28 months (HR: 6.61, [95% CI: 1.56, 27.96], moderate certainty of evidence). In two randomized trials, longer-term azathioprine maintenance therapy (>24 months) is associated with fewer relapses without an increase in adverse events. CONCLUSION This comprehensive systematic review synthesizes and evaluates the benefits and toxicities of different treatment options for GPA and MPA.
The effect of intravenous ferric carboxymaltose on health-related quality of life in iron-deficient patients with acute heart failure: the results of the AFFIRM-AHF study
European heart journal. 2021
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.
