Two items relevant to long COVID

One of the tricky issues in studying in long COVID is: how widely do researchers cast their net? Initial reports acknowledged that people who were hospitalized and in intensive care may take a while to get back on their feet. But the number of people who had SARS-CoV-2 infections and were NOT hospitalized, yet experienced lingering symptoms, may be greater. A recent report from the United Kingdom, published in PLOS Medicine, studied more than Read more

Signature of success for an HIV vaccine?

Efforts to produce a vaccine against HIV/AIDS have been sustained for more than a decade by a single, modest success: the RV144 clinical trial in Thailand, whose results were reported in 2009. Now Emory, Harvard and Case Western Reserve scientists have identified a gene activity signature that may explain why the vaccine regimen in the RV144 study was protective in some individuals, while other HIV vaccine studies were not successful. The researchers think that this signature, Read more

Candida auris

Combo approach vs drug-resistant fungus

Before 2020 and the COVID-19 pandemic, concern among infectious disease specialists was rising about Candida auris, an emerging fungal pathogen that is often drug-resistant and difficult to eradicate from hospitals.

Many people know Candida can cause mouth or vaginal infections and diaper rashes. According to the CDC, Candida also can cause invasive infections in the bloodstream, particularly in hospital or nursing home patients with weakened immune systems. About 30 percent of patients with an invasive Candida infection die – and C. auris is just one particularly hardy variety.

Emory Antibiotic Resistance Center director David Weiss and colleagues have identified a combination of existing antifungal drugs (micafungin and amphotericin B) with enhanced activity against C. auris when used together. The results – in vitro only, so far — were published in a letter to The Lancet Microbe. Postdoctoral fellow Siddharth Jaggavarapu was the first author. Weiss reports his team continues to investigate combination approaches against C. auris.
