Many patients with weak immune systems don’t realize their Evusheld Covid-19 medicine is as effective as in the past

Mon, 2022-11-14 17:14 — mike kraft

Many patients with weak immune systems don't realize their Covid-19 medicine isn't as effective as it used to be | CNN Judy Salins considers herself a smart, empowered patient, but until this week, she had no idea that the medicine she takes to defend herself against Covid-19 isn't protecting her as well as it used to. Elizabeth Cohen,Naomi Thomas CNN

...

The medicine is called Evusheld, and its effectiveness is waning dramatically because new Covid-19 subvariants are taking center stage, and the drug doesn’t neutralize all of them.

The Latest COVID-19 Variants Can Evade Vaccine Protection, According to New Data

New lab data suggest that vaccines and prior infections may not offer enough protection against several new COVID-19 variants cropping up in the U.S. and around the world.

Dr. David Ho, director of Columbia University’s Aaron Diamond AIDS Research Center, and his team reported the results from a set of studies published in the journal Nature. They showed how well some of the latest variants—BQ.1, BQ.1.1, XBB, and XBB.1, which were all derived from Omicron—are evading both vaccine-derived and infection-derived immunity.

Doctors are trying to understand why Covid Patients Coming Off Ventilators Can Take Weeks to Regain Consciousness

Mon, 2022-11-07 18:45 — mike kraft

In March 2020, New York City’s hospitals filled up with patients desperately ill with Covid-19. In many cases, when their fluid-filled lungs could no longer give them oxygen, doctors sedated them and put them on ventilators.

The patients who recovered were taken off the machines and anesthesia. Within a day or so, their doctors expected them to wake up.

The Pandemic Uncovered Ways to Speed Up Science There doesn't have to be a trade-off between good research and fast research. Saloni Dattani WIRED

The pandemic highlighted broad problems in research: that many studies were hyped, error-ridden, or even fraudulent, and that misinformation could spread rapidly. But it also demonstrated what was possible.

Mon, 2022-10-24 13:01 — mike kraft

Ivermectin: Still on a Losing Streak as COVID-19 Treatment | MedPage Today

WASHINGTON -- There were no differences in relief from mild-to-moderate COVID-19 symptoms for patients on ivermectin versus placebo, according to the ongoing ACTIV-6 trial.

Among >1,000 vaccinated and unvaccinated patients, the median time to recovery was 12 days for those in the ivermectin group and 13 days in the placebo group, reported Matthew McCarthy, MD, of Weill Cornell Medicine in New York City, at IDWeek.

As a result, the hazard ratio for improvement in time to recovery was 1.07 (95% credible interval 0.96-1.17, posterior P=0.91), McCarthy and colleagues stated in JAMA, where the results were simultaneously published.
