Do all antiphospholipid antibodies confer the same risk for major organ involvement in systemic lupus erythematosus patients?

Objectives: We aimed to investigate the association between the different antiphospholipid antibodies (aPL) and both systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS) manifestations.

Methods: Patients from the RELESSER registry, a Spanish retrospective, cross-sectional, forty-five hospital registry of adult SLE patients, were included.

Results: Out of a total of 3,658 SLE patients, 1372 were aPL positive (555 of them fulfilled criteria for APS).

Antiphospholipid syndrome (APS) in patients with systemic lupus erythematosus (SLE) implies a more severe disease with more damage accrual and higher mortality.

Introduction: Antiphospholipid antibodies (aPL) have been associated with organ damage and certain features in systemic lupus erythematosus(SLE) patients. Our aim was to investigate the differences between SLE patients according to the presence of aPL and/or clinical antiphospholipid syndrome (APS).

Materials And Methods: Patients from the RELESSER-T registry were included.

Clinical and therapeutic management of rheumatoid arthritis with biological disease-modifying antirheumatic drugs: RADAR study.

To describe the clinical and therapeutic management of rheumatoid arthritis (RA) patients with biological disease-modifying antirheumatic drugs (bDMARDs), alone or in combination with conventional synthetic DMARDs (csDMARDs), as well as analysing changes over time in bDMARD use. An observational, retrospective, multicentre study was conducted in the rheumatology departments of 10 public Spanish hospitals. Patients with RA treated with bDMARDs at baseline who had medical records available in the data collection period 2013-2016 were included.

Independent Candidate Serum Protein Biomarkers of Response to Adalimumab and to Infliximab in Rheumatoid Arthritis: An Exploratory Study.

Response to treatment of rheumatoid arthritis shows large inter-individual variability. This heterogeneity is observed with all the anti-rheumatic drugs, including the commonly used TNF inhibitors. It seems that drug-specific and target-specific factors lead individual patients to respond or not to a given drug, although this point has been challenged.

Transmission FTIR derivative spectroscopy for estimation of furosemide in raw material and tablet dosage form.

A Fourier transform infrared derivative spectroscopy (FTIR-DS) method has been developed for determining furosemide (FUR) in pharmaceutical solid dosage form. The method involves the extraction of FUR from tablets with N,N-dimethylformamide by sonication and direct measurement in liquid phase mode using a reduced path length cell. In general, the spectra were measured in transmission mode and the equipment was configured to collect a spectrum at 4 cm(-1) resolution and a 13 s collection time (10 scans co-added).

Reagent-free determination of amikacin content in amikacin sulfate injections by FTIR derivative spectroscopy in a continuous flow system.

The quantitative estimation of amikacin (AMK) in AMK sulfate injection samples is reported using FTIR-derivative spectrometric method in a continuous flow system. Fourier transform of mid-IR spectra were recorded without any sample pretreatment. A good linear calibration (>0.

Discovery of serum proteomic biomarkers for prediction of response to infliximab (a monoclonal anti-TNF antibody) treatment in rheumatoid arthritis: an exploratory analysis.

Biologics such as TNF antagonists are a new class of drugs that have greatly improved Rheumatoid Arthritis (RA) treatment. However, for unknown reasons, individual patients with RA respond to one of these drugs but not to others even those targeting the same molecule. Methods to predict response are sorely needed because these drugs are currently selected by trial and error, what is very inefficient and prejudicial for the patient and the healthcare system.

A new method for the analysis of amikacin using 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (AQC) derivatization and high-performance liquid chromatography with UV-detection.

A simple and sensitive reversed-phase liquid chromatographic method has been developed for the determination of amikacin (AMK) by derivatization. The method is based on the pre-column derivatization of AMK with 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate (AQC). The derivatization reaction proceeds in aqueous solution at room temperature with a borate buffer of pH 8.

A factorial design for optimizing a flow injection analysis system.

The use of a factorial design for the response exploration of a flow injection (FI) system is described and illustrated by FI spectrophotometric determination of paraquat. Variable response (absorbance) is explored as a function of the factors flow rate and length of the reaction coil. The present study was found to be useful to detect and estimate any interaction among the factors that may affect the optimal conditions for the maximal response in the optimization of the FI system, which is not possible with a univariate design.

[Extracorporeal lithotripsy in a young child. Use of the EDAP LT 01 apparatus in a 20-month-old girl].

The possibility for treating adults with renal stone by extracorporeal shock wave lithotripsy is proved to be an effective method. However, up to now, a few cases in the world were reported in childhood, never before the patient was 3 years old; although 65% of urinary stones in children can be observed before 3 years. We report the first successful application of the EDAP lithotriptor in the management of a twenty months little girl with upper urinary stone.
