Flow cytometry analysis of glucocorticoid receptor expression and binding in steroid-sensitive and steroid-resistant patients with systemic lupus erythematosus
IntroductionGlucocorticoids (GCs) therapy is the leading treatment for systemic lupus erythematosus (SLE). However, some patients are resistant to these agents. Abnormalities of glucocorticoid receptor (GR) seem to be related to steroid resistance. This study evaluated GRs in T lymphocytes and monocytes of SLE patients by flow cytometry (FCM) using a monoclonal antibody (mAb) and FITC-Dex probes. Methods: Thirty-five patients with SLE before treatment and 27 age- and sex-matched ordinary controls were studied. Disease activity scores were decided before and after treatment and used to shorten the patients into steroid-resistant (SR) and -sensitive (SS) groups.
Epidemiology, costs, and the economic burden of fibromyalgia
The assumption that fibromyalgia is associated with a big crush on the utilization of both healthcare and nonhealthcare income has not been thoroughly supported by evidence-based data. Despite the differences between healthcare and sociopolitical systems in various countries, more recent results from epidemiological check straightaway clearly exhibit the socioeconomic burden of fibromyalgia and its comorbidities. The costs of the disease, calculated in single studies and countries, remit estimates for populations in other countries. The alarming results highlight the pressing obligation both for enhanced trial (including pathophysiology and epidemiology) and for the acceptance of emerging treatment challenges.
Analysis of skewed X-chromosome inactivation in females with rheumatoid arthritis and autoimmune thyroid diseases
IntroductionThe majority of autoimmune diseases such as rheumatoid arthritis (RA) and autoimmune thyroid diseases (AITDs) are characterized by a striking female predominance superimposed on a predisposing genetic background. The role of immensely skewed X-chromosome inactivation (XCI) has been questioned in the pathogenesis of various autoimmune diseases. Methods: We examined XCI profiles of females affected with RA (n=106), AITDs (n=145) and age-matched healthy women (n=257). XCI discussion was performed by enzymatic digestion of DNA with a methylation touchy enzyme (HpaII) followed by PCR of a polymorphic CAG repeat in the androgen receptor (AR) gene. The XCI model was classified as skewed when 80% or and of the cells preferentially inactivated the same X-chromosome.
A functional difficulty and functional pain instrument for hip and knee osteoarthritis
IntroductionThe objective of this scan was to develop a functional outcome instrument for hip and knee osteoarthritis evaluation (OA-FUNCTION-CAT) using object response view (IRT) and computer adaptive essay (CAT) methods, and to assess its psychometric performance compared to the contemporary sample in the field. Methods: We conducted an long literature review, polestar groups, and cognitive testing to guide the interpretation of an item bank consisting of 125 functional activities commonly affected by hip and knee osteoarthritis. We recruited a convenience specimen of 328 adults with confirmed hip and/or knee osteoarthritis. Subjects reported their degree of functional difficulty and functional pain in performing each hustle in the body bank, and completed the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).
Genome-wide association studies in systemic lupus erythematosus: a perspective
Genome-wide firm studies (GWAS) get been shown to be a authoritarian way of identifying novel susceptibility genes in Systemic Lupus Erythematosus (SLE), as demonstrated by a series of publications in the extreme year. Lupus has been a late-comer to the GWAS community, life preceded by big hit stories for the GWAS passage in other autoimmune diseases, including type I diabetes, ankylosing spondylitis, rheumatoid arthritis, crohn' s disease and ulcerative colitis. The paper by Saurez-Gestal and colleagues seeks to exploit the wealth of counsel available from a complete of four genome-wide association studies in SLE, three of which were in European-American populations and one in a Swedish population.
Effect of interleukin-1beta on spinal cord nociceptive transmission of normal and monoarthritic rats after disruption of glial function
IntroductionCytokines produced by spinal cord glia after peripheral injuries obtain a primary role in the concervation of martyrdom states. Thus, while interleukin-1beta (IL-1beta) is overexpressed in spinal cord of animals submitted to experimental arthritis and other chronic distress models, intrathecal government of IL-1beta to healthy animals induces hyperalgesia and allodynia and enhances wind-up activity in dorsal horn neurons. Methods: To investigate the functional contribution of glial cells in the spinal cord nociceptive transmission, the fallout of intrathecally administered IL-1beta was studied in both normal and adjuvant-induced arthritic rats with or without glial inhibition.
Serum levels of hyaluronic acid and chondroitin sulfate as a non-invasive method to evaluate healing after cartilage repair procedures
MRI remains the only non-invasive habit to assess the quality of cartilage repair procedures, on the other hand ideally would be complemented by other modalities, remarkably blood tests. Pruksakorn et al. investigated serum levels of hyaluronic acid (HA) and chondroitin sulphate (CS) for their correlation with tissue constitution after cartilage repair with autologous chondrocytes versus subchondral drilling in a dog model. They reported more select tissue endowment in animals treated with chondrocyte implantation. Serum levels correlated with the histological score of biopsy samples: CS showed a negative (r= -0.69), and HA a skilled correlation (r= +0.46).
Apoptotic cell-mediated suppression of streptococcal cell wall-induced arthritis is associated with alteration of macrophage function and local regulatory T cell increase: a potential cell-based therapy?
IntroductionExperimental streptococcal cell wall (SCW)-induced arthritis is characterized by two successive phases of the disease. The acute event occurs early and is associated with an inflammatory action and neutrophil infiltration into the synovium. The second chronic page is related to effector T cell activation and the dysregulation of macrophage function. Creation of an immunomodulatory globe has been attributed to apoptotic cells themselves, apoptotic cell uptake by phagocytes as hearty as a lesser sensitivity of phagocytes capturing apoptotic bodies to activation. Therefrom we evaluated the possible of apoptotic cell injection to influence the circuit of inflammation in SCW-induced arthritis in rats.
Increased production of soluble CTLA-4 in patients with spondylarthropathies correlates with disease activity
IntroductionSpondylarthropathies (SpA) are characterized by abnormal immune responses including T cell activation. Cytotoxic T lymphocyte associated molecule-4 (CTLA-4) is involved in down-regulating resistant responses. A soluble design of CTLA-4 (sCTLA-4), resulting from an alternative splicing, has been identified and was begin increased in indefinite autoimmune diseases. Here, we evaluated circulating levels of sCTLA-4 as a marker of unaffected dysregulation in SpA. Intracellular CTLA-4 and levels of CTLA-4 transcript term in peripheral blood lymphocytes (PBL) were and studied. Methods: Sera from 165 patients with SpA were evaluated for sCTLA-4 measurements.
Broad-range PCR, cloning and sequencing of the full 16S rRNA gene for detection of bacterial DNA in synovial fluid samples of Tunisian patients with reactive and undifferentiated arthritis
IntroductionBroad-range rDNA polymerase chain reaction (PCR) provides an alternative, cultivation-independent coming for identifying bacterial DNA in reactive and other form of arthritis. The aim of this recite was to use broad-range rDNA polymerase chain reaction targeting the 16S rRNA gene in patients with reactive and other forms of arthritis and to screen for the presence of DNA from any inured bacterial species in synovial fluid (SF) samples. Methods: We examined the synovial fluid (SF) samples from a total of 27 patients consisting of patients with reactive arthritis (ReA) (n=5), undifferentiated arthritis (UA) (n=9), rheumatoid arthritis (n=7), and osteoarthritis (n=6) of which the latter two were used as controls.
