INTRODUCTION: Systemic sclerosis (SSc) is a severe and costly multiorgan autoimmune connective tissue disease characterised by vasculopathy and fibrosis. One of the major causes of SSc-related death is pulmonary arterial hypertension (PAH), which develops in 12-15% of patients with SSc and accounts for 30-40% of deaths. In situ thrombosis in the small calibre peripheral pulmonary vessels resulting from endothelial dysfunction and an imbalance of anticoagulant and prothrombotic mediators has been implicated in the complex pathophysiology of SSc-related PAH (SSc-PAH), with international clinical guidelines recommending the use of anticoagulants for some types of PAH, such as idiopathic PAH...

BACKGROUND AND OBJECTIVES: Long-term morbidity and mortality after heart transplantation (HTx) remain very high. Several reports have suggested that anti-HLA antibodies (anti-HLA-AB) detected after HTx might be associated with poor survival, but the implication of isolated anti-HLA-AB is still under debate. The aim of the study was to analyze the incidence of de novo anti-HLA-AB and whether they are associated with adverse events after HTx. METHODS: This retrospective study analyzed the presence of anti-HLA-AB assessed by fluorimetry (Luminex) and quantified by a single-antigen bead assay in 119 HTx patients...

Chronic kidney disease (CKD) is associated with increased cardiovascular mortality, and vascular smooth muscle cell (VSMC) dysfunction plays a pivotal role in uremic atherosclerosis. Axl signaling is involved in vascular injury and is highly expressed in VSMC. Recent reports have shown that cilostazol, a phosphodiesterase type 3 inhibitor (PDE3), can regulate various stages of the atherosclerotic process. However, the role of cilostazol in uremic vasculopathy remains unclear. This study aimed to identify the effect of cilostazol in VSMCs in the experimental CKD and to investigate whether the regulatory mechanism occurs through Axl signaling...

Introduction: Fetal thrombotic vasculopathy is a recently described placental alteration with varying degrees of involvement and often associated with adverse perinatal outcomes. The diagnosis is made histologically and therefore is postnatal, which makes it a challenge in clinical practice. Method: Case report and review of literature on the subject. Results: The present case refers to a pregnant woman presenting fetal growth restriction, with poor obstetrical past, and sent late to our service...

BACKGROUND: Donor-specific anti-HLA antibodies (DSA) are common after heart transplantation and are associated with rejection, cardiac allograft vasculopathy, and mortality. A noninvasive diagnostic test for pathologic antibody-mediated rejection (pAMR) does not exist. METHODS: From January 1, 2010, through August 31, 2013, 221 consecutive adult patients underwent heart transplantation and were followed through October 1, 2015. The primary objective was to determine whether the presence of DSA could detect AMR at the time of pathologic diagnosis...

Sickle cell disease (SCD) is an inherited haemoglobin disorder, associated with recurrent painful episodes, ongoing haemolytic anaemia and progressive multi-organ damage. Until the early 1990s, survival beyond the fourth decade for a patient with SCD was considered unusual and prompted case reports. Nowadays, in countries with developed health care systems, more than 90 percent of newborns with SCD survive into adulthood. Nevertheless, their life expectancy is still shortened by more than two decades compared to the general population...

PURPOSE: To compare the findings of optical coherence tomography angiography (OCTA) with indocyanine green angiography (ICGA) in polypoidal choroidal vasculopathy (PCV) that was divided into two types: polypoidal choroidal neovascularisation (CNV) and typical PCV (type 2 PCV). METHODS: We studied a retrospective case series of 32 patients with treatment-naïve PCV (24 men, eight women; mean age 65.4 years). PCV was categorised into polypoidal CNV (type 1 PCV) and type 2 PCV based on ICGA findings...

Polypoidal choroidal vasculopathy (PCV), the predominant subtype of neovascular age-related macular degeneration in the Asian population, is associated with genetic polymorphism of lipid metabolism. In this study, we performed the untargeted lipidomics approach of ultra-performance liquid chromatography coupled with mass spectrometry (UPLC-MS) to reveal the potential discriminating lipid profile of PCV patients in serum (21 PCV patients and 19 age-matched controls). Unsupervised principal component, supervised orthogonal partial least squares analysis, correlation analysis, and heatmap analysis were performed with the data obtained by UPLC-MS...

With improvements in the care of patients with sickle hemoglobinopathies, sickle cell disease (SCD) has evolved from a disease that was fatal in childhood into one in which most survive past their 5th decade and some into old age. As a result, the renal complications of sickle hemoglobinopathies, which are age dependent, have emerged as a common and serious complication of SCD. Approximately 14 - 18% of mortality in SCD is attributed to chronic kidney disease (CKD), which develops in 1/3 of individuals with SCD and progresses to end-stage renal disease in 4 - 18% of them...

Systemic sclerosis (SSc) is a systemic autoimmune disease characterized by vasculopathy, inflammation and fibrosis. These three main disease-determining pathways are the target of the currently available treatments used to possibly modify the progression of disease-related manifestations, although this synergy has not been fully applied on SSc joint, skin or lung involvement yet. Areas covered: we describe the current status of SSc treatment/therapy performing a literature search in MEDLINE/Pubmed and Thomson Reuter's Web of Science for articles published until March 2016...

PURPOSE OF REVIEW: Despite considerable advances in controlling acute rejection, the longevity of cardiac and renal allografts remains significantly limited by chronic rejection in the form of allograft vasculopathy. This review discusses recently reported mechanistic insights of allograft vasculopathy pathogenesis as well as recent clinical evaluations of new therapeutic approaches. RECENT FINDINGS: Although adaptive immunity is the major driver of allograft vasculopathy, natural killer cells mediate vasculopathic changes in a transplanted mouse heart following treatment with donor-specific antibody (DSA)...

BACKGROUND: Cellular therapies for immunomodulation in vascularized composite allotransplantation (VCA) have gained importance due to their potential minimization of immunosuppression. Adipose-derived mesenchymal stem cells (AD-MSCs) especially have shown encouraging potential. We investigated the influence of timing and frequency of AD-MSC-treatment on immunologic and graft survival as well as graft vasculopathy (GV) outcomes after VCA. METHODS: Lewis (LEW) rats received full-mismatched Brown Norway (BN) rat hindlimb transplants...
