3/17/25, NIH: “IRP’s Paul Hwang Discovers How Muscle Cells Gear Up for Training”

‘Dr. Hwang’s lab is also looking at a gene, WASF3, that disrupts the function of mitochondria, making muscle cells unable to accommodate exercise in people with chronic fatigue syndrome’

“It’s really hard to plan for discovery; instead, we follow the science, or, in this case, we follow the molecules,” Dr. Hwang says. “That’s one of the great things about NIH: we’re given the freedom to follow the science, and with my clinical background, do translational studies that bring clinical relevance to our findings about human biology.”

2/28/25, Make Visible: 'Understanding Complex Illness: Post-Pandemic prevalence of ME/CFS - what we can learn from the increase with Suzanne Vernon, PhD'

Vernon: “So, I think from a research perspective, the pandemic provided an unprecedented opportunity to study a large group of people that developed ME/CFS from the same exact trigger, and that being SARS-CoV-2 infection.”

“But again, the pandemic, the SARS-CoV-2 pandemic provided us with just an incredible opportunity now to look at this one entry way into ME/CFS.

Host: "I'm actually finding this with multiple researchers that whilst obviously post-COVID condition is not optimal for those suffering from it, and no one is saying that it's a good thing, it is providing this wealth of information that enables you to study these illnesses with that specific start point. And you have then gone on to write so many papers simply in those last five years, looking at the differences and similarities between the post-COVID and what you define as ME/CFS."

Vernon: "We focused on the 15,000 adult participants that were enrolled as the adult cohort in RECOVER...And then we just crunched the numbers. I mean, the nice thing about the RECOVER Initiative is it's a longitudinal study. So all of these people are followed every three months up until now. I mean, I think they're still being followed. So the data that was published in this paper was actually a data dump from as late as September of 2024. So really super, super fresh data and just an incredible data set.”

“RECOVER used, I mean, thank goodness they actually asked about post-exertional malaise and that's really thanks to a lot of advocacy from the ME/CFS community that was involved in the design of the RECOVER study.”

“I hope it's going to reveal a great deal about not only what is causing ME/CFS, but again, how it can be treated and what are the different targets that we can look at for treatment.”

Host: “Now, there has been a lot of criticism of RECOVER....I have heard it from researchers in the US who have said that they did not necessarily include sufficient people either with lived experience or with the depth of knowledge of post-viral conditions when they were designing their teams and their studies. You obviously, in terms of the data that you have been able to gather from RECOVER, have found it immensely useful. Can you tell me your thoughts on the way this is structured and the information that you feel that Recover should be able to bring us?”

Vernon: "...anyway, so it was a large group, 200 plus investigators initially, together with the NIH and people with lived experience involved in the design. Bateman Horne Center was one of the only groups that was involved in RECOVER that was actually, I think, funded to some level to be an investigator in there. So there was ME/CFS research and clinical expertise involved, but it was, I mean, at least it was there.”

“But I think we've made incredible progress at helping people understand post-COVID ME/CFS is there, is important, and needs to be part of the research. And that's evidenced by the fact that look at all these people on this paper. From academic institutions that I could have never have even imagined to have had the opportunity to work with. And these are all people that now, it's like, wow, this is ME/CFS. This is something. This is important."

“I'm really excited that this paper finally got published. I think it's evidence that we've been needing for a very long time. I'm also very excited by the RECOVER Initiative because we have not had a study of this scale ever, ever.”

“So, RECOVER has the opportunity, I think, to really provide that type of evidence base that has been really sought after by the pharmaceutical companies to get involved.”

Is there a thread on this study? Was looking and didn't find yet

CIDRAP: 'COVID-19 re-infection doubles risk of long COVID in kids, young adults, data reveal'

'The retrospective cohort study used data from the RECOVER consortium collected from 40 US children's hospitals from January 2022 through October 2023, when the Omicron variant was predominant. The study involved 465,717 patients 20 years old and younger with confirmed COVID-19 during the study period; the median age was 8 years. The study has not yet been peer-reviewed.'

Effectiveness of Paxlovid in Protecting Against Long COVID: EHR Insights
Speakers will present findings from two studies examining whether Paxlovid treatment in the acute phase of COVID-19 helps to prevent Long COVID. The study teams used electronic health records from the National Covid Cohort Collaborative (N3C) and the National Patient-Centered Clinical Research Networks (PCORnet) RECOVER repository.

Register for the seminar
Reminder that this starts in 1.5 hours.
 
They presented findings from two large observational studies of Paxlovid use during acute COVID, using a "Target Trial Emulation" methodology, which is an attempt to emulate an RCT as much as possible using observational data. They use statistical methods such as "Inverse Probability of Treatment Weighting" to control for as many possible confounders as possible.

PCORnet (see thread for study)
For the PCORnet study, they studied 497,499 patients. Paxlovid treatment was required to be within 5 days of infection.
159,659 high risk received treatment
5,597 low risk received treatment
272,048 high risk did not receive treatment
35,874 low risk did not receive treatment
When looking at incidence of long COVID over 180 days after infection, they found that about 3 fewer people developed long COVID per 100 people that were infected when taking Paxlovid. The hazard ratio was 0.88. (12% less likely to develop long COVID). Also found decreased incidence of hospitalization greater than 30 days after infection and decreased mortality with Paxlovid use.

They looked at the effect of Paxlovid on specific long COVID symptoms in various categories (neurologic, skin, pulmonary, etc). The hazard ratio is significantly less than 1 in almost every category (Paxlovid associated with decreased risk of LC). The two exceptions that were not significant were associations with hair loss and with receiving the long COVID diagnostic code U09.9.

They also looked separately at high risk and low risk patients. High risk means older age (≥ 50), smoker, or underlying conditions such as cancer or diabetes. There was a significant association of Paxlovid with decreased LC in high risk, but not low risk patients. When splitting by factors such as specific condition or age in the high risk population, the hazard ratios are still almost consistently significant when grouping based on these factors.

N3C (see thread for study)
This study on the N3C cohort also found decreased risk of long COVID with Paxlovid use. 1 fewer person per 366 infected when treated with Paxlovid [about 0.27 per 100 when comparing to 2.99 per 100 in PCORnet cohort].

There was a lower risk of long COVID when looking at the overall definition (RR=0.94, 95% CI: 0.92-0.97). When splitting by symptom clusters, there was significant decrease for cognitive phenotype (RR=0.86, 95% CI: 0.81-0.91) and fatigue/malaise phenotype (RR=0.92, 95% CI: 0.88-0.96), but not respiratory phenotype (RR=1.03, 95% CI: 0.97-1.09).

Also corroborated previously published findings about Paxlovid reducing risk of hospitalization and death.

-----

The findings were fairly close for relative risk between the cohorts showing a modest reduction in risk of long COVID in those who take Paxlovid during acute COVID infection, specifically in high risk patients.

The differences in absolute risk reduction were likely due to the different definitions used for long COVID. About 30% of people developed LC using rule-based PCORnet definition, versus only about 5% using machine learning-based N3C definition.

Edit: Fixed typo in relative risk value for fatigue/malaise phenotype.

MedPage Today: 'Will Memoli Be the Next NIAID Director?'

"During an on-camera interview with CBS News last week, HHS Secretary Robert F. Kennedy Jr. said that Matthew Memoli, MD -- currently the principal deputy director at NIH -- will be the next director of the National Institute of Allergy and Infectious Diseases (NIAID)."

"Memoli, "the top flu researcher at NIH, is going to be running NIAID," Kennedy said in response to a question from Jon LaPook, MD, CBS News chief medical correspondent, about who is making decisions about NIH research.”
 
Sharing for sight

From Sick Times newsletter:
  • An NIH study is assessing whether the tracer 11C-PS13 — a molecule injected into the body before an imaging scan — can help identify inflammation in people with neurological Long COVID. The study will enroll 60 people in Bethesda, Maryland, and will include up to five clinic visits over 11-14 weeks. Contact: Tara Turon, tara.turon@nih.gov.
 
1/30/25 - Univ. of Alabama Birmingham (UAB), Dept. of Pathology: 'Benson secures RECOVER grant to study effects of Long COVID'

'The grant will fund $158,000 per year and will run through April 2026.'

'Paul Benson, M.D., Professor and Autopsy Section Head in the Department of Pathology's Division of Anatomic Pathology, was awarded a Researching COVID to Enhance Recovery (RECOVER) grant from the National Institutes of Health for his project, titled, "A Multi-site Pathology Study of Post-Acute Sequelae of SARS-CoV-2 Infection'

"We believe the RECOVER tissue pathology (autopsy) study will inform Long COVID research and treatment options for years to come," Benson said.

'Autopsies will be performed to address the pathophysiology of the potential long-term effects of SARS-CoV-2 infection on human health'

Weren't all those RECOVER grants cancelled by the new administration?
