INTRODUCTION: Anetoderma is an elastolytic skindisorder that has been associated with the presenceof antiphospholipid antibodies (aPL). Patients withantiphospholipid antibody-positive anetoderma havebeen reported to develop symptoms of Graves disease,antiphospholipid syndrome, and other autoimmuneconditions. The temporal relationship, however,between anetoderma onset and the emergence ofaPL remains unclear, a clarification of which may haveimplications for the screening and monitoring ofpatients with anetoderma...

Therapy-related acute promyelocytic leukemia (t-APL) is relatively rare, with limited data on outcome after treatment with arsenic trioxide (ATO) compared to standard intensive chemotherapy (CTX). We evaluated 103 adult t-APL patients undergoing treatment with all-trans retinoic acid (ATRA) alone (n=7) or in combination with ATO (n=24), CTX (n=53), or both (n=19). Complete remissions were achieved after induction therapy in 57% with ATRA, 100% with ATO/ATRA, 78% with CTX/ATRA, and 95% with CTX/ATO/ATRA. Early death rates were 43% for ATRA, 0% for ATO/ATRA, 12% for CTX/ATRA, and 5% for CTX/ATO/ATRA...

Harringtonine (HT) is a promising natural product that is mainly isolated from plants of the genus Cephalotaxus. Due to its remarkable antileukemic activities, HT has been utilized clinically in China for the treatment of acute promyelocytic leukemia (APL). No antibody that recognizes free HT has been reported to date due to the difficulty of preparing antigen conjugates in which haptens bind to a carrier protein. To overcome this difficulty, we focused on sodium periodate (NaIO4), which catalyzes unique oxidative reactions; the resulting conjugates enabled the production of a highly specific monoclonal antibody (MAb) against HT (MAb 1D2) and the establishment of an indirect competitive enzyme-linked immunosorbent assay (icELISA) for the determination of HT...

MicroRNAs (miRNAs) are one class of endogenous non-coding RNAs that involved in post-transcriptional regulation of the gene. MiRNAs through interaction with messenger RNA (mRNA) involved in several biological processes such as cell cycle, differentiation, growth, metabolism, aging and apoptosis. MiRNAs may act as an oncogene or a tumor suppressor via up or down regulation in cancerous cells. MiR-182 located in a miR-183/-96/-182 cluster, this is the highly conserved cluster to have an important role in cancer development and tumorigenesis...

Although acute promyelocytic leukemia (APL) is a curable hematologic malignancy, early death (ED) remains a significant cause of treatment failure especially in developing countries. In a retrospective data analysis of 67 adult APL patients diagnosed in United Arab Emirates we report an ED rate of 11.9% which is comparable to that reported from more developed countries. We identified the following parameters at presentation as significant predictor of increased ED: Age >40 years (P = 0.015), fever (P = 0...

Background: Acute promyelocytic leukemia (APL) is a unique subtype of acute leukemia. APL is a curable disease; however, drug resistance, early mortality, disease relapse and treatment-related complications remain challenges in APL patient management. One issue underlying these challenges is that the molecular mechanisms of the disease are not sufficiently understood. Materials and Methods: In this study, we performed a meta-analysis of gene expression profiles derived from microarray experiments and explored the background of disease by functional and pathway analysis...

BACKGROUND: Antiphospholipid antibodies (aPLs) namely anticardiolipin (aCL) antibody, anti-β2-glycoprotein I (β2GPI) antibody and lupus anticoagulant (LA) are autoantibodies produced against anionic phospholipids and proteins on plasma membranes. Migraine is a primary headache disorder which has growing evidences of autoimmune-mediated pathogenesis and previous studies suggested the presence of aPLs in migraine patients. AIMS: The aim of this study was to evaluate the comorbid association between aPLs (aCL, anti-β2GPI and LA) and migraine compared to healthy controls...

The delta neutrophil index (DNI) reflects the fraction of circulating immature granulocytes. We evaluated the usefulness of DNI values in patients with acute myeloid leukemia (AML) to distinguish the acute stage of acute promyelocytic leukemia (APL). We analyzed patients retrospectively who were first diagnosed with AML upon admission to the emergency department (ED). Thirty of the 134 patients (22.4%) were diagnosed with APL on ED admission. The univariate analysis and multivariate logistic regression models revealed that DNI values differed significantly between APL and non-APL AML patients on days 0, 1 and 2...

Persistent serum positivity for antiphospholipid antibodies (aPL) is required to diagnose antiphospholipid syndrome (APS), an autoimmune disease characterized by recurrent vascular thrombosis and/or pregnancy morbidity. The current therapeutic management of patients with thrombotic APS aims at preventing recurrences and long-term complications by attenuating the procoagulant state. There is overall consensus to reserve moderate-intensity anticoagulation to aPL-positive patients with a previous venous thrombosis; the therapeutic options for those with a history of arterial event comprise antiplatelet agents and high-intensity anticoagulation...

Catastrophic antiphospholipid syndrome (CAPS) is a rare, life-threatening disease. In 1992, Asherson defined it as a widespread coagulopathy related to the antiphospholipid antibodies (aPL). CAPS requires rapid diagnosis and prompt initiation of treatment. Areas covered: This paper discusses all aspects of CAPS, including its pathophysiology, clinical manifestations, diagnostic approaches, differential diagnoses, management and treatment of relapsing CAPS, and its prognosis. To obtain the information used in this review, scientific databases were searched using the key words antiphospholipid antibodies, catastrophic antiphospholipid syndrome, hemolytic anemia, lupus anticoagulant, and thrombotic microangiopathic hemolytic anemia...

All-trans retinoic acid (atRA) is a front-line treatment for acute promyelocytic leukemia (APL). Due to its activity in regulating the cell cycle, it has also been evaluated for the treatment of other cancers. However, the efficacy of atRA has been limited by atRA inducing its own metabolism during therapy, resulting in a decrease of atRA exposure during continuous dosing. Frequent relapse occurs in patients receiving atRA monotherapy. In an attempt to combat therapy resistance, inhibitors of atRA metabolism have been developed...

Nested PCR (nPCR) and real-time quantitative PCR (qPCR) are well-established methods for monitoring minimal residual disease (MRD) in acute promyelocytic leukemia (APL). Despite their remarkable sensitivity and specificity, both methods have inherent limitations, such as qualitative MRD evaluation and relative quantification. Herein, we used droplet digital PCR (ddPCR) to monitor MRD in 21 APL patients and compared its performance with nPCR and qPCR. After assessing the limit of detection (LOD) for each technique on serial dilutions of PML-RARA bcr1 and bcr3 transcripts, a total of 48 follow-up samples were analyzed and the results compared...

The antiphospholipid syndrome (APS) is defined by the development of venous and/or arterial thromboses, often multiple, and pregnancy morbidity (mainly, recurrent fetal losses), in the presence of antiphospholipid antibodies (aPL). Some estimates indicate that the incidence of the APS is around 5 new cases per 100,000 persons per year and the prevalence around 40-50 cases per 100,000 persons. The aPL are positive in approximately 13% of patients with stroke, 11% with myocardial infarction, 9.5% of patients with deep vein thrombosis and 6% of patients with pregnancy morbidity...

Many pathogens, including the malaria parasite Plasmodium falciparum, display high levels of polymorphism within T-cell epitope regions of proteins associated with protective immunity. The T-cell epitope variants are often non-cross-reactive. Herein, we show in a murine model, which modifies a protective CD8 T-cell epitope from the circumsporozoite protein (CS) of Plasmodium berghei (SYIPSAEKI), that simultaneous or sequential co-stimulation with two of its putative similarly non-cross-reactive altered peptide ligand (APL) epitopes (SYIPSAEDI or SYIPSAEAI) has radically different effects on immunity...
