Background: Multiple Sclerosis (MS) is an inflammatory and demyelinating disease of the central nervous system. Oxidative stress plays a major role in the onset and progression of MS. Asymmetric dimethylarginine (ADMA) formation is dependent on oxidative stress status.
Objective: We examined whether alpha-lipoic acid (ALA) as a potent antioxidant could improve the Expanded Disability Status Scale (EDSS) and decrease plasma level of ADMA in multiple sclerosis patients.
Methods: In a randomized, double-blinded clinical trial conducted at Sina Hospital in Tehran, Iran, from September 2009 to July 2011, 24 patients with relapsing-remitting MS were divided into a treatment group receiving ALA (1200mg/day) for 12 weeks and a control group receiving placebo. Then patients’ EDSS and Plasma levels of ADMA were measured at baseline and 12 weeks later. Statistical analysis was done by SPSS software version 16 using the K-S test, Chi square, Mann–Whitney U-test and Wilcoxon test.
Results: The plasma levels of ADMA in the intervention group were decreased significantly (p=0.04). Also, no patient had increased EDSS score in the supplement group, where 2 out of 12 patients in the placebo group experienced so. Comparing the serum level of ADMA between the two groups failed to show any significant change in the supplement group compared with the control group.
Conclusion: Considering that ADMA is produced by oxidative stress in MS patients and leads to increase of inflammation, ALA may have the potential of beneficial effects in them, in part, by decreasing the plasma level of ADMA and stopping progression.
Trial registration: The trial was registered at the Iranian Registry of Clinical Trials (http://www.irct.ir) with the Irct ID: No. IRCT138812222602N2.

Ethics of Publishing Case Reports: Do We Need Ethics Approval and Patient Consent?
An editorial by Dr. Mehrdad Jalalian
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

Lessons from COVID-19 pandemic and the Morocco’s success story.
An editorial by Dr. Benksim Abdelhafid (Morocco)
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.
