Project description:Heyde syndrome manifests as aortic stenosis associated with gastrointestinal bleeding. We describe the case of a 64-year-old man who came to the emergency room due to acute heart failure and intermittent gastrointestinal bleeding. Treatment involves initial correction of anemia and heart failure followed by aortic valve replacement. The prosthesis used depends on the characteristics of each patient and valve replacement allows the resolution of bleeding in most cases. Gastrointestinal bleeding in patients with aortic stenosis is associated with severity of the valve obstruction. A mechanical prosthesis was used with no recurrent bleeding even with the need for lifelong anticoagulation therapy.

Project description:AimsHeyde syndrome is the co-occurrence of aortic stenosis, acquired von Willebrand syndrome, and gastrointestinal bleeding. Aortic valve replacement has been demonstrated to resolve all three associated disorders. A systematic review and meta-analysis were performed to obtain best estimates of the effect of aortic valve replacement on acquired von Willebrand syndrome and gastrointestinal bleeding.Methods and resultsA literature search was performed to identify articles on Heyde syndrome and aortic valve replacement up to 25 October 2022. Primary outcomes were the proportion of patients with recovery of acquired von Willebrand syndrome within 24 h (T1), 24-72 h (T2), 3-21 days (T3), and 4 weeks to 2 years (T4) after aortic valve replacement and the proportion of patients with cessation of gastrointestinal bleeding. Pooled proportions and risk ratios were calculated using random-effects models. Thirty-three studies (32 observational studies and one randomized controlled trial) on acquired von Willebrand syndrome (n = 1054), and 11 observational studies on gastrointestinal bleeding (n = 300) were identified. One study reported on both associated disorders (n = 6). The pooled proportion of Heyde patients with acquired von Willebrand syndrome recovery was 86% (95% CI, 79%-91%) at T1, 90% (74%-96%) at T2, 92% (84%-96%) at T3, and 87% (67%-96%) at T4. The pooled proportion of Heyde patients with gastrointestinal bleeding cessation was 73% (62%-81%). Residual aortic valve disease was associated with lower recovery rates of acquired von Willebrand syndrome (RR 0.20; 0.05-0.72; P = 0.014) and gastrointestinal bleeding (RR 0.57; 0.40-0.81; P = 0.002).ConclusionAortic valve replacement is associated with rapid recovery of the bleeding diathesis in Heyde syndrome and gastrointestinal bleeding cessation. Residual valve disease compromises clinical benefits.

Project description:BackgroundHeyde syndrome (HS) is known as the association of severe aortic stenosis (AS) and recurrent gastrointestinal bleeding (GIB) from angiodysplasia. Data on the prevalence of HS and results after TAVI remain scarce.Methods2548 consecutive patients who underwent TAVI for the treatment of AS from 2008 to 2017 were evaluated for a history of GIB and the presence of HS. The diagnosis of HS was defined as a clinical triad of severe AS, a history of recurrent GIB, and an endoscopic diagnosis of angiodysplasia. These patients (Heyde) were followed to investigate clinical outcomes, bleeding complications and the recurrence of GIB and were compared to patients with GIB unrelated to HS (Non-Heyde).ResultsA history of GIB prior to TAVI was detected in 190 patients (7.5%). Among them, 47 patients were diagnosed with HS (1.8%). Heyde patients required blood transfusions more frequently compared to Non-Heyde patients during index hospitalization (50.0% vs. 31.9%, p = 0.03). Recurrent GIB was detected in 39.8% of Heyde compared to 21.2% of Non-Heyde patients one year after TAVI (p = 0.03). In patients diagnosed with HS and recurrent GIB after TAVI, the rate of residual ≥ mild paravalvular leakage (PVL) was higher compared to those without recurrent bleeding (73.3% vs. 38.1%, p = 0.05).ConclusionA relevant number of patients undergoing TAVI were diagnosed with HS. Recurrent GIB was detected in a significant number of Heyde patients during follow-up. A possible association with residual PVL requires further investigation to improve treatment options and outcomes in patients with HS.

Project description:BackgroundHeyde syndrome is the co-occurrence of aortic stenosis and gastrointestinal bleeding secondary to angiodysplasias. Surgical aortic valve replacement effectively reduces bleeding, but the effects of transcatheter aortic valve implantation (TAVI) are largely unknown. This study aimed to describe the reduction of gastrointestinal bleeding in patients with Heyde syndrome after TAVI and to identify the factors associated with rebleeding.MethodsWe enrolled patients with Heyde syndrome from a prospective TAVI registry. Gastrointestinal bleeding episodes were assessed by the Bleeding Academic Research Consortium classification, and cumulative incidence functions were used to calculate cessation rates. Factors potentially associated with rebleeding were analyzed using logistic regression. Differences between Heyde and non-Heyde patients were assessed through a case-cohort study.ResultsBetween December 2008 and June 2020, 1111 patients underwent TAVI. There were 70 patients with Heyde syndrome (6.3%). In the first year following TAVI, gastrointestinal bleeding ceased in 46 of 70 patients (62% [95% CI, 50%-74%]). Bleeding episodes decreased from 3.2 (95% CI, 2.5-4.2) to 1.6 ([95% CI, 1.2-2.2] P=0.001) and hemoglobin levels increased from 10.3 (95% CI, 10.0-10.8) to 11.3 (95% CI, 10.8-11.6) g/dL (P=0.007). Between 1 and 5 years after TAVI (35 [interquartile range, 21-51] months), 53 of 62 patients (83% [95% CI, 72%-92%]) no longer experienced gastrointestinal bleeding. Paravalvular leakage (≥mild) was associated with rebleeding risk (odds ratio, 3.65 [95% CI, 1.36-9.80]; P=0.010). Periprocedural bleeding was more common in Heyde than in control patients (adjusted odds ratio, 2.55 [95% CI, 1.37-4.73]; P=0.003).ConclusionsPatients with Heyde syndrome are at increased risk for periprocedural bleeding. Post-TAVI, gastrointestinal bleeding disappears in the majority of patients. Paravalvular leakage may curtail these clinical benefits.

Project description:ObjectiveA systematic review of international case reports of patients with Heyde syndrome (HS) treated by transcatheter aortic valve implantation (TAVI) was conducted to explore the clinical characteristics of this group of patients and sirgical success. Methods: Electronic databases, including PubMed, Embase and CNKI, were searched with combinations of the search terms, Heyde syndrome, gastrointestinal bleeding, aortic stenosis, angiodysplasia and transcatheter aortic valve replacement. All case reports were screened according to inclusion criteria, and HS patient data was summarized.ResultsA total of 31 case reports concerned patients with a history of aortic stenosis and repeated gastrointestinal bleeding. Ultrasonic cardiograms (UCG) were recorded for 27 cases, including those with critical aortic stenosis (n = 26). Gastrointestinal sequelae were reported in 22 cases with duodenal and jejunal being the most common (n = 9). High-molecular-weight multimers of von Willebrand Factor (vWF-HMWM) were measured in 17 cases with the majority being lower (n = 15) and the minority normal (n = 2). All patients experienced recurrent bleeding after medication and endoscopic therapy and symptoms improved after TAVI (31/31). vWF was at normal levels in 11/12 cases post-TAVI. Twenty-five patients were followed up and 22 had no recurrence of symptoms giving an efficacy rate of 88% for TAVI in HS patients.ConclusionsHS is characterized by angiodysplasia, aortic stenosis and von Willebrand disease with frequent recurrence of bleeding after drug and endoscopic treatment. TAVI is an effective therapy with an 88% resolution rate.

Project description:Asthma is associated with a significant burden of disease, especially for patients with severe or uncontrolled asthma. Many patients with severe asthma still receive treatment in primary care settings and despite the availability of effective options, inadequate asthma treatment remains a concern, particularly the use of systemic corticosteroids to treat exacerbations and severe asthma. Around the world, many patients are stuck in a vicious circle of misdiagnosis, undertreatment, and poor understanding of disease severity and management. In this manuscript, we describe the development of The Asthma Referral Identifier (ReferID) tool, a simple, 4-item questionnaire that healthcare providers can use to help identify patients with uncontrolled and/or potentially severe asthma. ReferID was developed specifically for use in primary care clinics in low- and middle-income countries and other clinics, where the optimisation of asthma assessments and treatment recommended for countries with well-established healthcare systems, are not possible. ReferID was developed through an informal collaborative process involving international asthma experts as well as general practitioners, nurses, and specialists throughout the Asia Pacific, Latin America and Middle East regions, in conjunction with current evidence and treatment guidelines. In collaboration with local and regional partners around the world, the developers have adapted ReferID and translated it into 21 languages, and implementation is ongoing in 30 countries. ReferID has the potential to help break the vicious circle, improving disease outcomes and health-related quality of life for patients with asthma.

Project description:Osteoporosis (OP) is significant and debilitating comorbidity of chronic obstructive pulmonary disease (COPD). We hypothesize that genetic variance identified with OP may also play roles in COPD. We have conducted a large-scale relation data analysis to explore the genes implicated with either OP or COPD, or both. Each gene linked to OP but not to COPD was further explored in a mega-analysis and partial mega-analysis of 15 independently collected COPD RNA expression datasets, followed by gene set enrichment analysis (GSEA) and literature-based pathway analysis to explore their functional linked to COPD. A multiple linear regression (MLR) model was built to study the possible influence of sample size, population region, and study date on the gene expression data in COPD. At the first step of the analysis, we have identified 918 genes associated with COPD, 581 with OP, and a significant overlap (P<2.30e-140; 210 overlapped genes). Partial mega-analysis showed that, one OP gene, GPNMB presented significantly increased expression in COPD patients (P-value = 0.0018; log fold change = 0.83). GPNMB was enriched in multiple COPD pathways and plays roles as a gene hub formulating multiple vicious COPD pathways included gene MMP9 and MYC. GPNMB could be a novel gene that plays roles in both COPD and OP. Partial mega-analysis is valuable in identify case-specific genes for COPD.

Project description:Sickle cell disease (SCD) is a genetic disease caused by a single mutation in the ?-globin gene, leading to the production of an abnormal hemoglobin called hemoglobin S (HbS), which polymerizes under deoxygenation, and induces the sickling of red blood cells (RBCs). Sickled RBCs are very fragile and rigid, and patients consequently become anemic and develop frequent and recurrent vaso-occlusive crises. However, it is now evident that SCD is not only a RBC rheological disease. Accumulating evidence shows that SCD is also characterized by the presence of chronic inflammation and oxidative stress, participating in the development of chronic vasculopathy and several chronic complications. The accumulation of hemoglobin and heme in the plasma, as a consequence of enhanced intravascular hemolysis, decreases nitric oxide bioavailability and enhances the production of reactive oxygen species (ROS). Heme and hemoglobin also represent erythrocytic danger-associated molecular pattern molecules (eDAMPs), which may activate endothelial inflammation through TLR-4 signaling and promote the development of complications, such as acute chest syndrome. It is also suspected that heme may activate the innate immune complement system and stimulate neutrophils to release neutrophil extracellular traps. A large amount of microparticles (MPs) from various cellular origins (platelets, RBCs, white blood cells, endothelial cells) is also released into the plasma of SCD patients and participate in the inflammation and oxidative stress in SCD. In turn, this pro-inflammatory and oxidative stress environment further alters the RBC properties. Increased pro-inflammatory cytokine concentrations promote the activation of RBC NADPH oxidase and, thus, raise the production of intra-erythrocyte ROS. Such enhanced oxidative stress causes deleterious damage to the RBC membrane and further alters the deformability of the cells, modifying their aggregation properties. These RBC rheological alterations have been shown to be associated to specific SCD complications, such as leg ulcers, priapism, and glomerulopathy. Moreover, RBCs positive for the Duffy antigen receptor for chemokines may be very sensitive to various inflammatory molecules that promote RBC dehydration and increase RBC adhesiveness to the vascular wall. In summary, SCD is characterized by a vicious circle between abnormal RBC rheology and inflammation, which modulates the clinical severity of patients.
