Will 14-3-3η Be a New Diagnostic and Prognostic Biomarker in Rheumatoid Arthritis? A Prospective Study of Its Utility in Early Diagnosis and Response to Treatment

Aim of the Work. To evaluate diagnostic and prognostic capacity of 14-3-3η protein in early RA, investigate its pathogenic and theragnostic role, and find its correlations with disease activity and severity in established RA patients. Subjects and Methods: 80 patients with early RA, 80 patients with established RA, and 80 healthy controls were included in this study. ROC curve analysis of RF, ACCP, and 14-3-3η in early disease was conducted, and serum levels of 14-3-3η were assessed by ELISA and reassessed in early RA patients 6 months after anti-TNF therapy. Correlation of 14-3-3η with parameters of disease activity and severity was analyzed. Results. Serum14-3-3η levels were significantly higher in all RA patients than in controls P<0.001, its sensitivity was 86.7% and 88.3% in early and established RA patients with a significant difference with RF and ACCP at early disease, and the specificity was 96.7%. There was a significant reduction of 14-3-3η levels 6 months after treatment in the first group p=0.004, and there was a significant positive correlation between serum 14-3-3η levels and parameters of disease activity and severity. Conclusion. 14-3-3η could be a novel, potent, and efficacious diagnostic, and prognostic marker for RA with high sensitivity, that may become a new therapeutic target for RA

The clinical musculoskeletal ultrasonography: Egyptian guidelines for structured musculoskeletal ultrasound scanning and reporting

Abstract Background The aim of this work is to set up the standards for performing musculoskeletal ultrasound scans and reporting as an additional procedure in the rheumatology setting. We used two rounds of the Delphi approach to get the consensus on a musculoskeletal ultrasound reporting. Results Fifteen expert panels had completed the two rounds of surveys. After the end of round two, eighteen recommendations distributed upon eight domains were released. The percentage of the agreement on the recommendations was 93.3 to 100 %. All eighteen key questions were answered at the end of the second round with agreement. Conclusion A musculoskeletal ultrasound report template has been developed by this study, based on outcomes of a Delphi process, by an international participants’ panel. All domains met the 80% voting threshold set in this work. The reporting template can be used for both clinical research as well as standard practice to provide guidance and standardize the musculoskeletal ultrasound reporting
