Efficacy and safety of regenerative cell therapy for pulmonary arterial hypertension in animal models: a preclinical systematic review protocol

The objective of this systematic review is to compare the efficacy and safety of regenerative cell therapies in preclinical models of PAH as well as assess study quality to inform future clinical studies. Methods We will include preclinical studies of PAH in which a regenerative cell type was administered and outcomes compared to a disease control. The primary outcome will be pulmonary hemodynamics as assessed by measurement of right ventricular systolic pressure and/or mean pulmonary arterial pressure. Secondary outcomes will include mortality, survival, right ventricular remodeling, pulmonary vascular resistance, cardiac output, cardiac index, pulmonary acceleration time, tricuspid annular systolic excursion, and right ventricular wall thickness. Electronic searches of MEDLINE and EMBASE databases will be constructed and reviewed by the Peer Review of Electronic Search Strategies (PRESS) process. Search results will be screened independently in duplicate. Data from eligible studies will be extracted, pooled, and analyzed using random effects models. Risk of bias will be assessed using the SYstematic Review Centre for Laboratory animal Experimentation (SYRCLE) risk of bias tool, and individual study reporting will be assessed according to an itemized checklist based on the Animal Research: Reporting of In vivo Experiments (ARRIVE) guidelines. Discussion This systematic review will examine...

ConclusionsWe report robust association of novel genesKLK1 andGGCX with IPAH, accounting for ~  0.4% and 0.9% of PAH Biobank cases, respectively. Both genes play important roles in vascular hemodynamics and inflammation but have not been implicated in PAH previously. These data suggest new genes, pathogenic mechanisms, and therapeutic targets for this lethal vasculopathy.

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...

ConclusionVascular surgery in TA cases becomes an option when the patient does not improve clinically after administration of medical treatment. Although endovascular management has fewer complications, the rate of restenosis is higher. Patients at risk of restenosis and who have increased perioperative vascular risk can benefit from open surgical procedures. Surgical management should be tailored to the patient’s needs.

Abstract Acromegaly is a rare disease caused by excessive production of growth hormone (GH), typically by a pituitary tumour. The diagnosis is usually delayed, and patients frequently develop various complications that cause premature mortality. In patients with hypertension, heart failure, diabetes, and arthropathies that are not age-specific, attention should be paid to signs of acromegaly. Insulin-like growth factor 1 (IGF-1) assay should be used as a screening test whenever acromegaly is suspected. Further diagnostic investigations and treatment should be carried out at specialist centres. First-line treatment...

This article aims to increase awareness of IPF among cardiologists, providing an overview for cardiologists on the differenti al diagnosis of IPF from HF, and describing the signs and symptoms that would warrant referral to a pulmonologist with expertise in ILD. Once patients with IPF have received a diagnosis, cardiologists can have an important role in managing patients who are candidates for a lung transplant or those w ho develop pulmonary hypertension (PH). Group 3 PH is one of the most common cardiovascular complications diagnosed in patients with IPF, its prevalence varying between reports but most often cited as be...

Authors: Riera-Mestre A, Ribas J, Castellote J Abstract Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant inherited Rare Disease that causes a systemic anomalous vascular overgrowth. The approach and follow-up of these patients should be from multidisciplinary units. Its diagnosis is carried out according to Curaçao clinical Criteria. Telangiectasia in the nasal mucosa cause recurrent epistaxis, the main symptom of HHT and difficult to control. The three types of hepatic shunting, hepatic artery to hepatic vein, hepatic artery to portal vein or to portal vein to hepatic vein, can cause hi...

Abstract BACKGROUND: Sarcoidosis is an increasingly recognized multi-systemic condition. Cardiac sarcoidosis is associated with ventricular arrhythmias and higher mortality rates. Little epidemiological data is available regarding the disease and associated ventricular arrhythmias. METHODS: Data from the National Inpatient Sample (NIS) database 2012-2014, were reviewed. Discharges associated with sarcoidosis were identified as the target population using relevant ICD-9-CM codes. Primary outcome was a diagnosis of ventricular tachycardia (VT) in the sarcoidosis population. Secondary outcomes include rate of ve...

ConclusionsThese data strongly implicateSOX17 as a new risk gene contributing to PAH-CHD as well as idiopathic/familial PAH. Replication in other PAH cohorts and further characterization of the clinical phenotype will be important to confirm the precise role ofSOX17 and better estimate the contribution of genes regulated by SOX17.
