Triple positive profile in antiphospholipid syndrome: prognosis, relapse and management from a retrospective multicentre study.

Objective: Antiphospholipid syndrome (APS) is defined by the association of thromboembolic and/or obstetrical clinical manifestations and the presence of antiphospholipid antibodies. The objective of our study was to evaluate the impact of the triple-positive profile in a cohort of 204 APS patients.

Methods: We conducted a retrospective study, including patients with primary or secondary APS, meeting the Sydney criteria with at least one thrombotic and/or obstetrical complication.

Kidney disease in antiphospholipid antibody syndrome: Risk factors, pathophysiology and management.

Antiphospholipid antibody syndrome (APLS) is a rare autoimmune disease characterized by recurrent arterial and venous thromboembolic events, pregnancy related complications as well as the persistent detection of antiphospholipid antibodies at a 12 week interval. Renal complications tend to occur in 3% of APLS patients, with renal artery stenosis being the most common kidney related complication. Renal pathology may be subdivided into macro as well as microvascular thrombotic complications with stenosis, thrombosis and infarction representing the principle macrovascular events and APLS nephropathy representing the predominant microvascular complication.

Clinical and prognostic significance of antinuclear antibodies in primary antiphospholipid syndrome: A multicenter retrospective study.

Introduction: The antiphospholipid syndrome (APS) (1) is defined by the development of vascular thrombosis, or pregnancy morbidity in the presence of persistent antiphospholipid antibodies (aPL). Antinuclear antibodies (ANA) can be detected in primary APS patients without any clinical systemic autoimmune disease. The presence of ANA antibodies could confer a specific phenotype in primary APS.

Gain-of-Function Mutation in Filamin A Potentiates Platelet Integrin αβ Activation.

Objective: Dominant mutations of the X-linked filamin A () gene are responsible for filaminopathies A, which are rare disorders including brain periventricular nodular heterotopia, congenital intestinal pseudo-obstruction, cardiac valves or skeleton malformations, and often macrothrombocytopenia.

Approach And Results: We studied a male patient with periventricular nodular heterotopia and congenital intestinal pseudo-obstruction, his unique X-linked allele carrying a stop codon mutation resulting in a 100-amino acid-long FLNa C-terminal extension (NP_001447.2: ).

In vitro combination of anidulafungin and voriconazole against intrinsically azole-susceptible and -resistant Aspergillus spp.

In vitro interaction of anidulafungin with voriconazole was tested by a microdilution broth checkerboard technique and an agar diffusion method against 30 Aspergillus clinical isolates belonging to five different species. By using a complete inhibition endpoint, indifferent interactions were observed for 97% of the isolates by the checkerboard technique (FIC index from 0.5 to 2) and for 100% of the isolates by the agar diffusion method (variation of -2 to +1 log(2) dilutions).

[Importance of hemolysis on neuron-specific enolase measurement].

The aim of this work is to establish a pre-analytical approach suitable for the neuron-specific enolase (NSE) measurement. This enzyme which is synthesized by neurons and neuroendocrine cells, is a marker useful for the diagnosis and the monitoring of patients with neuroendocrine tumors (neuroblastoma, small cell lung cancer) and during stroke to assess neuronal damage. This NSE measurement is very sensitive to hemolysis due to the abundance of the enzyme in red blood cells.
