Resumen Los anticuerpos contra el ácido desoxirribonucleico [DNA] en el laboratorio clínico, están íntimamente ligados al diagnóstico y monitorización del lupus eritematoso sistémico [LES]; no obstante, las características de los métodos analíticos y las propiedades de los propios anticuerpos son heterogéneas Revisar la definición y propiedades de los anticuerpos anti-DNA de doble cadena [anti-dsDNA], la adecuación de los métodos analíticos y los requerimientos clínicos para este biomarcador. A través de PubMed se investiga la bibliografía existente con los términos anti-dsDNA, editorial, review, guideline, meta-analysis y LES. La última búsqueda, anti-dsDNA y LES restringuida a los últimos dos años. Se amplía información a través de artículos relacionados y los publicados en organismos oficiales estatales relacionados con anti-dsDNA y LES. Se analizan los métodos del laboratorio clínico para el análisis de los anti-dsDNA y sus características. Se revisa la utilidad clínica de los anti-dsDNA en sus aspectos diagnóstico, de asociación clínica y seguimiento del LES. Existe una amplia variabilidad en los métodos analíticos y persisten déficits en la estandarización. Forman parte de los criterios actuales clasificatorios de LES y se utilizan como marcadores en el seguimiento de la enfermedad. La utilidad diagnóstica mejora cuando se determinan en pacientes con ANA positivos. En el seguimiento, es interesante la cuantificación, preferiblemente con el mismo método analítico (dado los déficits de estandarización).

Abstract Objectives Anti-deoxyribonucleic acid (DNA) antibodies in the clinical laboratory are intimately linked to the diagnosis and monitoring of systemic lupus erythematosus (SLE); however, the characteristics of the analytical methods and the properties of the antibodies themselves are heterogeneous. To review the definition and properties of anti-double-stranded anti-DNA (anti-dsDNA) antibodies, the adequacy of analytical methods, and the clinical requirements for this biomarker. Content Through PubMed we searched the existing literature with the terms anti-dsDNA, editorial, review, guideline, meta-analysis and SLE. The last search, anti-dsDNA and SLE restricted to the last two years. Information was expanded through related articles and those published in official state bodies related to anti-dsDNA and SLE. Summary Clinical laboratory methods for anti-dsDNA analysis and their characteristics are analyze. The clinical utility of anti-dsDNA in its diagnostic, clinical association and follow-up aspects of SLE is reviewed. Outlook There is wide variability in analytical methods and deficits in standardization persist. They are part of the current SLE classification criteria and are used as markers in the follow-up of the disease. Their diagnostic usefulness improves when they are determined in antinuclear antibody (ANA)-positive patients. In follow-up, quantification is of interest, preferably with the same analytical method (given the deficits in standardization).

The purpose of the systematic review and meta-analysis was to determine if low-ratio n-6/n-3 long-chain polyunsaturated fatty acid (PUFA) supplementation affects serum inflammation markers based on current studies.

Abstract Scientific findings have indicated that psychological and social factors are the driving forces behind most chronic benign pain presentations, especially in a claim context, and are relevant to at least three of the AMA Guides publications: AMA Guides to Evaluation of Disease and Injury Causation, AMA Guides to Work Ability and Return to Work, and AMA Guides to the Evaluation of Permanent Impairment. The author reviews and summarizes studies that have identified the dominant role of financial, psychological, and other non–general medicine factors in patients who report low back pain. For example, one meta-analysis found that compensation results in an increase in pain perception and a reduction in the ability to benefit from medical and psychological treatment. Other studies have found a correlation between the level of compensation and health outcomes (greater compensation is associated with worse outcomes), and legal systems that discourage compensation for pain produce better health outcomes. One study found that, among persons with carpal tunnel syndrome, claimants had worse outcomes than nonclaimants despite receiving more treatment; another examined the problematic relationship between complex regional pain syndrome (CRPS) and compensation and found that cases of CRPS are dominated by legal claims, a disparity that highlights the dominant role of compensation. Workers’ compensation claimants are almost never evaluated for personality disorders or mental illness. The article concludes with recommendations that evaluators can consider in individual cases.
