hemolysis in aps

Ying-Liang Gong, Yu-Feng Li
We present a case of acute post-streptococcal glomerulonephritis (APSGN) with autoimmune hemolytic anemia (AIHA). Along with the classic findings of APSGN, the patient had a positive direct antiglobulin test and an anticardiolipin antibody without any typical clinical manifestations of antiphospholipid syndrome (APS). This case raises questions of the relationship between Streptococcus and the development of autoimmune hemolytic anemia in children. Our case highlights the possibility that the streptococcal infections in this patient might be responsible for her anemia, either in setting of underlying antiphospholipid antibodies, or in having triggered the development of pathogenic antibodies, which subsequently leads to the clinical evolution of hemolysis...

Trichomonas vaginalis genome encodes ∼440 proteases, six of which are aspartic proteases (APs). However, only one belongs to a clan AA (EC, family A1 (pepsin A), cathepsin D-like protease. This AP is encoded by an 1113-bp gene (tv-catd), which translates into a 370-aa residues zymogen of 40.7-kDa and a theoretical pI of 4.6, generating a ∼35 kDa active enzyme after maturation (Tv-CatD). The goal of this study was to identify and analyze the effect of glucose on the expression of Tv-CatD at the transcript and protein levels, subcellular localization, and proteolytic activity...

Tumor cells have an increased demand for amino acids to support their rapid growth and malignant metastasis. Transfer of amino acids across plasma membranes depends on several amino acid transporters that are highly upregulated in tumor cells and are promising targets for tumor cell-selective therapy. In this study, stealth liposomal systems functionalized with aspartate-polyoxyethylene stearate conjugate (APS) were developed for transporter-mediated targeted delivery to ATB(0,+), which is overexpressed human lung cells...

Catastrophic antiphospholipid syndrome (CAPS) is an accelerated form of the antiphospholipid antibody syndrome resulting in multi-organ ischemia and failure. It is a rare and life-threatening condition that can be easily mistaken with hemolysis elevated liver enzymes low platelets syndrome, thrombotic thrombocytopenic purpura, and hemolytic uremic syndrome. In order to make a diagnosis, it is required to have multi-organ thrombosis over 1 week affecting at least three organs or systems, and to have positive antiphospholipid antibody on two occasions (6 weeks apart), and histopathologic confirmation of small vessel occlusion...

Carotid-artery atherosclerosis is a common cause of ischemic stroke. Carotid-artery stenting (CAS) is one of the most effective treatments. However, In-stent restenosis (ISR) and re-endothelialization delay are two major issues of intravascular stent which affect clinical safety and reduce effects. In this study, atomic layer deposition (ALD) technology was applied to deposit a layer (10nm) of Al2O3 on Nitinol surface as an intermediate functional layer. The alumina covered surface was then modified with a coupling agent 3-aminopropyltriethoxysilane (APS) and heparin sequentially in order to improve the hemocompatibility of Nitinol stents...

A stable, biocompatible and exquisite SPIONs-PEG-HER targeting complex was developed. Initially synthesized superparamagnetic iron oxide nanoparticles (SPIONs) were silanized using 3-aminopropyltrimethoxysilane (APS) as the coupling agent in order to allow the covalent bonding of polyethylene glycol (PEG) to the SPIONs to improve the biocompatibility of the SPIONs. SPIONs-PEG were then conjugated with herceptin (HER) to permit the SPIONs-PEG-HER to target the specific receptors expressed over the surface of the HER2+ metastatic breast cancer cells...

Pre-eclampsia complicated by severe HELLP (hemolysis, elevated liver enzymes and low platelet count) syndrome is a multi-organ disease, and can be difficult to differentiate from thrombotic microangiopathy (appearing as thrombotic thrombocytopenic purpura or hemolytic uremic syndrome), acute fatty liver, systemic erythematous lupus, antiphospholipid syndrome and severe sepsis. Many papers have highlighted the risks of misdiagnosis resulting in severe consequences for maternal health, and this can be fatal when thrombotic thrombocytopenic purpura is misdiagnosed as severe HELLP syndrome...

HELLP syndrome is a collection of symptoms described as hemolysis, elevated liver enzymes and low platelets. HELLP syndrome complicates 0.01-0.6% of pregnancies and can be considered a severe variant of preeclampsia. The occurrence of HELLP syndrome diagnosed before the 20th week of gestation has been most commonly reported in association with antiphospholipid antibody syndrome (APS) or triploid chromosomal anomalies. A 41-year-old primigravida was admitted at 17 weeks and 6 days gestation with hypertension, proteinuria, hemolytic anemia and acute renal injury...

The aim of this study was to investigate the antioxidant potential of ampelopsin (APS) by using various methods in vitro, as well as to determine effects of APS on LPS-induced oxidative stress in piglets. The results showed that APS exhibited excellent free radical scavenging by DPPH, ABTS, O2•-, H2O2 and ferric reducing antioxidant power. Ampelopsin also protected pig erythrocytes against AAPH-induced apoptosis and hemolysis, decreased total superoxide dismutase activity, and increased lipid peroxidation...

Obstetrical antiphospholipid syndrome (APS) is defined by obstetrical complications and the presence of antiphospholipid antibodies (aPL). Although the incidence of APS is still poorly known, this thrombophilia is now recognized as one of the most common acquired causes of recurrent fetal loss. The diagnosis of APS during pregnancy can be challenging because of its various clinical features. Mothers with APS have an increased risk of thrombosis, thrombopenia, and specific pregnancy‑related complications such as preeclampsia, eclampsia, and hemolysis elevated liver enzyme and low‑platelet syndrome...

Microangiopathic antiphospholipid-associated syndromes (MAPSs) are reported as encompassing several conditions mainly affecting the microvasculature of selected organs: the liver in HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet); kidney, brain, and skin in TTP (thrombotic thrombocytopenic purpura). It is predominant in patients with catastrophic antiphospholipid syndrome (APS). A recent report suggests that APS is not only a thrombotic disease but also associated with microangiopathic features, and it can explain the greater prevalence of HELLP syndrome in these patients...

Antiphospholipid syndrome (APS) is associated with a risk of obstetrical complications, affecting both the mother and the fetus. Obstetrical APS is defined by a history of three consecutive spontaneous miscarriages before 10 weeks of gestation (WG), an intra-uterine fetal death after 10 WG, or a premature birth before 34 WG because of severe pre-eclampsia, eclampsia or placental adverse outcomes (intrauterine growth retardation, oligohydramnios). Pregnancy in women with a diagnosis of obstetric APS is at increased risk for placental abruption, HELLP (Hemolysis, Elevated Liver enzymes, Low Platelet count) syndrome and thrombosis that may be part of a catastrophic antiphospholipid syndrome (CAPS)...
