“Complementary treatments for osteoarthritis (OA) are sought by patients for symptomatic relief and to avoid the iatrogenic effects of non-steroidal anti-inflammatories. This systematic review evaluates the efficacy of the nutritional supplement Perna Canaliculus (green-lipped mussel, GLM) in the treatment of OA and substantially adds to previous work by focussing solely
on GLM use in OA as well providing a re-analysis of the original trial data. Randomized or quasi-randomized controlled trials (comparative, placebo-controlled or crossover) were considered for inclusion from Cochrane Library, Medline, Embase, Amed, Cinahl, Scopus and NeLH databases where adults with OA of any joint were randomized to receive either GLM vs. placebo, no additional SHP099 mouse intervention (usual care), or an active intervention. The methodological quality of the trials was assessed using the JADAD scale. Four RCTs were included, three placebo controlled, the fourth a comparative trial of GLM lipid extract vs. stabilized powder extract. No RCTs comparing GLM to conventional treatment were identified. All four studies assessed GLM as an adjunctive treatment to conventional medication for a clinically relevant time in mild to moderate OA. All trials reported clinical benefits in the GLM treatment group
but the findings from two studies cannot be included in this review because of possible un-blinding and inappropriate statistical analysis. The data from the learn more two more rigorous trials, in conjunction with our re-analysis of original data suggests that GLM may be superior to placebo for the treatment of mild to moderate OA. As a credible biological mechanism exists for this Molecular motor treatment, further rigorous investigations are required to assess efficacy and optimal dosage.”
“Stromal fibroblasts are the primary cells of the kidney that produce fibrotic matrix. CD248
is a stromal marker expressed on fibroblasts and pericytes within the human kidney. Here, we tested whether CD248 expression in the kidney colocalizes with fibrosis and if it is associated with known determinants of chronic kidney disease (CKD). CD248 expression was located and quantified in situ by immunohistochemistry in kidney biopsies from 93 patients with IgA nephropathy and compared with 22 archived biopsies encompassing normal kidney tissue as control. In normal kidney tissue, CD248 was expressed by resident pericytes, stromal fibroblasts, and was upregulated in human CKD. The expression was linked to known determinants of renal progression. This relationship was maintained in a multivariate analysis with CD248 expression linked to renal survival. CD248 was expressed by a population of alpha-smooth muscle actin (SMA)(+) myofibroblasts and alpha-SMA(-) stromal cells but not expressed on CD45(+) leukocytes.
