Antiphospholipid syndrome (APS) is an autoimmune disease characterized by thrombosis and/or pregnancy morbidity with persistently positive antiphospholipid antibodies (aPL). Patients with aPL may also experience thrombocytopenia, cardiac valve disease, nephropathy, skin ulcer, or cognitive dysfunction, which are collectively known as non-criteria manifestations of APS. A description is provided of two primary APS patients who received belimumab (10 mg/kg) for an aPL-related manifestation.

Antiphospholipid syndrome (APS) is an acquired autoimmune condition characterized by thrombotic events, pregnancy morbidity, and laboratory evidence of antiphospholipid antibodies (aPL). Management of these patients includes the prevention of a first thrombotic episode in at-risk patients (primary prevention) and preventing recurrent thrombotic complications in patients with a history of thrombosis (secondary prevention). Assessment of thrombotic risk in these patients, balanced against estimated bleeding risks associated with antithrombotic therapy could assist clinicians in determining whether antithrombotic therapy is warranted...

Acute promyelocytic leukemia (APL) is a unique subtype of acute myeloid leukemia (AML), which presents with a distinct coagulopathy. Therapeutic advances have made APL one of the true success stories in oncology, transforming this once lethal disease into the most curable form of AML. For many patients, cure will now be achieved without the use of chemotherapy. It is hoped that limiting chemotherapy will reduce mortality even further, particularly among more vulnerable older adults whose survival lagged behind that of younger patients...

Amino acid mutations to agonist peptide epitopes of myelin proteins have been used to modulate immune responses and experimental autoimmune encephalomyelitis (EAE, animal model of multiple sclerosis). Such amino acid alteration are termed, altered peptide ligands (APL). We have shown that the agonist myelin basic protein (MBP) 87-99 epitope (MBP87-99) with crucial T cell receptor (TCR) substitutions at positions 91 and 96 (K(91),P(96) (TCR contact residues) to R(91),A(96); [R(91),A(96)]MBP87-99) results in altered T cell responses and inhibits EAE symptoms...

OBJECTIVES: Hydroxychloroquine (HCQ) has been used for decades to treat patients with rheumatic diseases, for example, systemic lupus erythematosus (SLE), rheumatoid arthritis or the antiphospholipid syndrome (APS). We hypothesise that HCQ might target endosomal NADPH oxidase (NOX), which is involved in the signal transduction of cytokines as well as antiphospholipid antibodies (aPL). METHODS: For in vitro experiments, monocytic cells were stimulated with tumour necrosis factor α (TNFα), interleukin-1β (IL-1β) or a human monoclonal aPL and the activity of NOX was determined by flow cytometry...

Small ubiquitin-like modifier (SUMO)/sentrin-specific protease 1 (SENP1), a member of the SENP family, is highly expressed in several neoplastic tissues. However, the effect of SENP1 in acute promyelocytic leukemia (APL) has not been elucidated. In the present study, it was observed that SENP1 deficiency had no effect on the spontaneous apoptosis or differentiation of NB4 cells. Arsenic trioxide (As2O3) could induce the upregulation of endoplasmic reticulum (ER) stress, resulting in the apoptosis of NB4 cells...

Inorganic arsenicals are well-known carcinogens, whereas arsenite (iAs(III)) compounds are now recognized as potent therapeutic agents for several leukemias, and arsenic trioxide has been used for the treatment of recurrent acute promyelocytic leukemia (APL). However, recent clinical trials revealed that arsenite is not always effective for non-APL malignancies. Another arsenical, S-dimethylarsino-glutathione ([DMA(III)(GS)]), which is a putative metabolic intermediate in the hepatic metabolism of iAs(III), shows promise for treating several types of lymphoma...

Two new bacterial strains designated as Ant6(T) and Ant18 were isolated from the muscle of a fish which had been caught in the Antarctic Ocean. Both strains are Gram-stain-positive, catalase positive, oxidase negative, aerobic, and coccoid bacteria. Phylogenetic analysis based on the 16S rRNA gene sequences of strains Ant6(T) and Ant18 revealed that the strains Ant6(T) and Ant18 belong to the genus Deinococcus in the family Deinococcaceae in the class Deinococci. The highest degrees of sequence similarities of strains Ant6(T) and Ant18 were found with Deinococcus alpinitundrae LMG 24283(T) by 96...

Inappropriate cell proliferation during oncogenesis is often accompanied by inactivation of components involved in the cell cycle machinery. Here, we report that cyclin-dependent kinase inhibitor 2C (CDKN2C) as a member of the cyclin-dependent kinase inhibitors is a target of the PML/RARα oncofusion protein in leukemogenesis of acute promyelocytic leukemia (APL).We found that CDKN2C was markedly downregulated in APL blasts compared with normal promyelocytes. Chromatin immunoprecipitation combined with quantitative polymerase chain reaction demonstrated that PML/RARα directly bound to the CDKN2C promoter in the APL patient-derived cell line NB4...

The current recommendation for catastrophic antiphospholipid syndrome (CAPS) management is the standard triple therapy with anticoagulation (AC), glucocorticoids (GCs), plasma exchange (PE), and/or intravenous immunoglobulins (IVIGs). Of note, only AC has a significant effect on the prognosis of these patients. However, from the experimental or basic point of view, there is only indirect evidence to advocate the use of these immunomodulatory therapies (GC, PE, and IVIG) in CAPS. Recently, there have been reports of severe or refractory CAPS patients treated with the monoclonal antibodies rituximab and eculizumab...

INTRODUCTION: Crohn's disease (CD) is a progressive inflammatory disease affecting the entire gastrointestinal tract. The need for a definitive stoma (DS) is considered as the ultimate phase of damage. It is often believed that the risk of further disease progression is small when a DS has been performed. AIMS: The goals of the study were to establish the rate of CD recurrence above the DS and to identify predictive factors of CD recurrence at the time of DS. METHODS: We retrospectively reviewed all medical records of consecutive CD patients having undergone DS between 1973 and 2010...

BACKGROUND: Premature atherosclerosis is observed in systemic lupus erythematosus (SLE). Oxidative modification of LDL is associated with atherosclerotic plaque formation. OBJECTIVES: We hypothesized that anti-oxidized LDL (oxLDL) and anti-phospholipid (APL) in SLE sera would segregate with specific antibody subsets, and that anti-oxLDL antibodies will linger in circulation over an extended period. PATIENTS AND METHODS: Sixty-seven SLE and control subjects and two SLE subjects with sera collected longitudinally for 13 years were tested for anti-oxLDL and IgG/IgM/IgA APL antibodies...

BACKGROUND: Previous research suggested that single gene expression might be correlated with acute myeloid leukemia (AML) survival. Therefore, we conducted a systematical analysis for AML prognostic gene expressions. METHODS: We performed a microarray-based analysis for correlations between gene expression and adult AML overall survival (OS) using datasets GSE12417 and GSE8970. Positive findings were validated in an independent cohort of 50 newly diagnosed, non-acute promyelocytic leukemia (APL) AML patients by quantitative RT-PCR and survival analysis...
