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

Bits from HIV + Aging conference

What conferences like the HIV + Aging meeting recently held by Emory in Decatur offer the visiting writer: anecdotes that illustrate issues of clinical care.

To illustrate her point that assumptions about who is likely to develop a new HIV infection may lead doctors to miss possible diagnoses, keynote speaker Amy Justice from Yale described a patient who was seen last year at Yale-New Haven Hospital.

A 60 year old man reported fatigue and had lost 40 pounds over the course of a year. Despite those symptoms, and the discovery of fungal and viral infections commonly linked to HIV/AIDS, it took nine months before a HIV test was performed on the patient, a delay Justice deplored.

Sex and substance abuse do not end at age 50, she said, citing data showing that the risk of HIV transmission can be greater among older adults, and that substance abuse is more likely among adults who are HIV positive compared to those who are HIV negative.

Justice also highlighted the issue of polypharmacy (interactions between prescription drugs at the same time), a concern even in people who are not living with HIV. Common blood pressure medications taken by older adults to prevent heart disease have been suspected of increasing the risk for falls. That’s a problem especially for people living with HIV, because HIV infection has been linked to weakened bone. Read more
