Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more

Reddit as window into opioid withdrawal strategies

Drug abuse researchers are using the social media site Reddit as a window into the experiences of people living with opioid addiction. Abeed Sarker in Emory's Department of Biomedical Informatics has a paper in Clinical Toxicology focusing on the phenomenon of “precipitated withdrawal,” in collaboration with emergency medicine specialists from Penn, Rutgers and Mt Sinai. Precipitated withdrawal is a more intense form of withdrawal that can occur when someone who was using opioids starts medication-assisted treatment Read more

CROI: HIV cure report and ongoing research

The big news out of CROI (Conference on Retroviruses and Opportunistic Infections) was a report of a third person being cured of HIV infection, this time using umbilical cord blood for a hematopoetic stem cell transplant. Emory’s Carlos del Rio gave a nice overview of the achievement for NPR this morning. As del Rio explains, the field of HIV cure research took off over the last decade after Timothy Brown, known as “the Berlin patient,” Read more

ACC 2016: Stem cell study sees improved heart failure outcomes

Patients with heart failure who received an experimental stem cell therapy experienced a reduced rate of death, hospitalization and unplanned clinic visits over the next year compared to a placebo group, according to results presented Monday at the American College of Cardiology meeting in Chicago.

The results of the ixCELL-DCM study were published online Monday by The Lancet. It was reportedly the largest cell therapy study done in patients with heart failure so far (58 treated vs 51 placebo).

Emory University School of Medicine investigators led by Arshed Quyyumi, MD, and their patients participated in the study, and Emory was one of the largest enrolling sites. Lead authors were Timothy Henry, MD of Cedars-Sinai Heart Institute in Los Angeles and Amit Patel, MD of the University of Utah.

“For the first time, a clinical trial has shown that administration of a cellular therapeutic results in an improvement in cardiac outcomes based on a prespecified analysis,” an editorial accompanying the paper in The Lancet says.

This study, which was sponsored by Vericel Corporation, was phase II, meaning that a larger phase III study will be needed before FDA approval. Read more
