Introduction: Direct detection of microbial super antigens in synovial fluid of patients with rheumatoid arthritis may be able to guide to the design of cost-effective therapies. The purpose of this study was to assess the existence of Staphylococcal enterotoxin A (superantigen A) in the synovial fluid of patients with RA by the PCR and ELISA methods.
Methods: This experimental study was conducted on the synovial fluid of 103 RA patients from Baqiyatallah University of Medical Sciences’ Rheumatology Clinic in Tehran, Iran in 2011-2014. Bacterial cultures, polymerase chain reaction with specific primer pairs and enzyme-linked immunosorbent assay (ELISA) methods were used. The PCR products were subjected to sequence as a confirmatory molecular method results. The data were descriptively analyzed by SPSS Version 19.
Results: The bacteriological study result indicated that, in four cases (3.8%) of the patients, bacterial strains were isolated. The result of PCR molecular method for staphylococcal enterotoxin A gene showed that, 42 of the patients (40.7%) tested positive for the ent A gene. The results of ELISA were positive for staphylococcal enterotoxin A (superantigen A) in 51 cases (49.51%) of the patients’ synovial fluids. The results indicated that the possibility of detecting superantigen A in the SF of RA patients, but the origin of the enterotoxin A gene remained unknown.
Conclusions: The findings of this study may be able to alter the actual theory on the pathogenesis, diagnosis, and treatment of RA patients. In addition, the results have shown the probability of an endogenous origin for the involved superantigen A in RA patients’ synovial fluids.

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.
To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here

The 6th World Conference on Research Integrity (WCRI) is to be held on June 2-5, 2019 in Hong Kong.
The WCRI is the largest and most significant international conference on research integrity. Since the first conference in Lisbon in 2007, it has given researchers, teachers, funding agencies, government officials, journal editors, senior administrators, and research students opportunities to share experiences and to discuss and promote integrity in research.
