Warren symposium follows legacy of geneticist giant

If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics. Stephen T. Warren, 1953-2021 Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more

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

An effective alternative to fecal transplant for C. difficile?

Bacterial spores in capsules taken by mouth can prevent recurrent C. difficile infection, results from a preliminary study suggest.

Clostridium difficile is the most common hospital-acquired infection in the United States and can cause persistent, sometimes life-threatening diarrhea. Fecal microbiota transplant has shown promise in many clinical studies as a treatment for C. difficile, but uncertainty has surrounded how such transplants should be regulated and standardized. Also, the still-investigational procedure is often performed by colonoscopy, which may be difficult for some patients to tolerate.

The capsule study, published Monday in Journal of Infectious Diseases, represents an important step in moving away from fecal microbiota transplant as a treatment for C. difficile, says Colleen Kraft, MD, assistant professor of pathology and laboratory medicine and medicine (infectious diseases) at Emory University School of Medicine.

Kraft and Tanvi Dhere, MD, assistant professor of medicine (digestive diseases) have led development of the fecal microbiota transplant program at Emory. They are authors on the capsule study, along with investigators from Mayo Clinic, Massachusetts General Hospital, Miriam Hospital (Rhode Island), and Seres Therapeutics, the study sponsor.

While this study involving 30 patients did not include a control group, the reported effectiveness of 96.7 percent compares favorably to published results on antibiotic treatment of C. difficile infection or fecal microbial transplant. Read more
