Monkeypox presentations, prevention strategies shifting

Article Type

Three months after the World Health Organization declared monkeypox a public health emergency, clinical presentations and vaccination strategies are evolving.

New areas of concern include transmissions among people experiencing homelessness and severe cases in immunocompromised persons.

Agam K. Rao, MD, with the Poxvirus and Rabies Branch of the Centers for Disease Control and Prevention, updated the global picture during an annual scientific meeting on infectious diseases: As of Oct. 14, the confirmed worldwide cases number 73,288, with more than one-third of them (27,317) in the United States. Case counts in the United States, however, have been decreasing since early August.

Cases have been most commonly found in men who have sex with men (MSM), though monkeypox has also been diagnosed in cisgender and transgender women, children, and men who do not report recent sex with other men.

Shift away from White men

Dr. Rao described a demographic shift in infections from White, non-Hispanic men early on to non-Hispanic Black and Hispanic men.

“There’s a lot of emphasis right now at CDC to try to understand these spreads, whether they are household [transmission] or another contact. We know that some of the women have had sexual contact with men who were diagnosed with monkeypox,” Dr. Rao said.

In children under age 12, direct skin-to-skin contact with household members seems to be the source, she said. In adolescents, as in adults, the main source seems to be male-male consensual sex.

“And just as in adults, Black and Hispanic children have been disproportionately affected,” she said.

No sustained spread outside MSM

Dr. Rao said that so far there has been no sustained spread detected beyond the MSM community. A CDC study of inmates in Cook County Jail in Chicago at the end of September, she noted, found no secondary cases.

However, health care workers are another group that was suspected to be at higher risk given close contact with patients, although there have been only three confirmed exposures. Sharps injuries from unroofed lesions are tied to some of those confirmed or suspected cases.

“We do not recommend unroofing lesions,” she said. “We’re getting very good samples from just rigorous swabbing of the lesions.”

She said that the CDC is also monitoring “a few hundred” cases, some of them severe, among people experiencing homelessness.

“We are working to try to understand the exposures that have occurred to those individuals and whether transmission has occurred person-to-person,” Dr. Rao said.

Severe cases among immunocompromised

Also of concern are people with compromised immune systems owing to advanced HIV or organ or stem cell transplants.

Among immunocompromised persons, Dr. Rao said, “we’re seeing large necrotic lesions affecting a large percentage of body surface, lesions that continue to develop over weeks.”

Boghuma Titanji, MD, PhD, MSc, a physician-scientist at Emory University in Atlanta, and an emerging-disease specialist, addressed the difference in presentations between immunocompromised and immunocompetent patients.

She said the main distinction is the extent of the lesions. Patients with AIDS and very low CD4 counts, for instance, are presenting with more lesions and have a longer course of illness.

Dr. Rao said in an interview, “It’s really important to understand someone’s immune status and understand whether they are severely immunocompromised. If there is a concern that a person has monkeypox, also testing for HIV concurrently may be important. It could be a missed opportunity to evaluate for it, especially given the fact that these can occur together.”

Assessing the size and appearance of the lesions is important to understanding whether patients could develop severe infection, she said.

 

 

Differences from past epidemics

Dr. Titanji said the current outbreak has some differences from historic outbreaks.

The incubation period, for instance, has tended to be shorter than in previous outbreaks – now 7-10 days, with a range of 5-14 days instead of a range of up to 21 days in previous outbreaks.

There are also more cases of presentations with only single lesions, which were infrequent in past epidemics, she said.

The scope of suspected cases has also broadened, with changing clinical features.

“We have expanded the clinical descriptions to include presentations that involve isolated rectal presentation – individuals presenting solely with rectal pain as the primary manifestation of monkeypox – or presenting with a sore throat as the only manifestation,” she said.

Expanding the case definition will help identify who should be tested.

“Monkeypox is an incredible clinical mimic,” Dr. Titanji said. “The rash can really take the form of a lot of the things we encounter on a regular basis in ID. It’s important to always have a low index of suspicion to test patients when they fit the right epidemiological profile.”

Vaccine strategy has evolved

Brett Petersen, MD, MPH, captain of the U.S. Public Health Service with the CDC, said that Jynneos, licensed by the U.S. Food and Drug Administration, continues to be the primary vaccine for monkeypox. However, the strategy has changed.

Whereas the initial vaccine strategy was to administer the vaccine after known exposure, the guidance now includes vaccinating after “both known and presumed exposures, as described in the eligible populations.”

It’s now been expanded even further to include preexposure inoculations for a wide group of people at greater risk, he explained.

Early data from the CDC indicate that the Jynneos vaccine is effective.

In a report updated in September, the CDC found that among 32 U.S. jurisdictions, monkeypox incidence was much higher among at-risk, unvaccinated people for whom vaccination is recommended than among those who got the Jynneos vaccine.

“Unvaccinated people had 14 times the risk of monkeypox disease compared to people who were vaccinated,” the CDC reported.

Asked about the end goal for monkeypox, Dr. Petersen said, “Our goal should be elimination. I think that is an achievable goal, but it will depend on a lot of factors and a lot of continued public health efforts.”

Dr. Rao, Dr. Titanji, and Dr. Petersen declared no relevant financial relationships.

More data suggest preexisting statin use improves COVID outcomes

Article Type

Preexisting statin use may help protect hospitalized patients with COVID-19 against negative outcomes, including death, a large retrospective analysis suggests.

Compared with patients who didn’t take statins, statin users had better health outcomes. For those who used these medications, the researchers saw lower mortality, lower clinical severity, and shorter hospital stays, aligning with previous observational studies, said lead author Ettore Crimi, MD, of the University of Central Florida, Orlando, and colleagues in their abstract, which was part of the agenda for the Anesthesiology annual meeting.

They attributed these clinical improvements to the pleiotropic – non–cholesterol lowering – effects of statins.

“[These] benefits of statins have been reported since the 1990s,” Dr. Crimi said in an interview. “Statin treatment has been associated with a marked reduction of markers of inflammation, such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), interleukin-6 (IL-6), ferritin, and white blood cell count, among others.”

He noted that these effects have been studied in an array of conditions, including cancer, autoimmune diseases, chronic inflammatory disease, and in the perioperative setting, and with infectious diseases, including COVID-19.

In those previous studies, “preexisting statin use was protective among hospitalized COVID-19 patients, but a large, multicenter cohort study has not been reported in the United States,” Dr. Crimi and his colleagues wrote in their abstract.

To address this knowledge gap, they turned to electronic medical records from 38,875 patients hospitalized with COVID-19 from January to September 2020. Almost one-third of the population (n = 11,533) were using statins prior to hospitalization, while the remainder (n = 27,342) were nonusers.

The primary outcome was all-cause mortality. Secondary outcomes included death from COVID-19, along with a variety of severe complications. While the analysis did account for a range of potentially confounding variables, the effects of different SARS-CoV-2 variants and new therapeutics were not considered. Vaccines were not yet available at the time the data were collected.

Statin users had a 31% lower rate of all-cause mortality (odds ratio, 0.69; 95% confidence interval, 0.64-0.75; P = .001) and a 37% reduced rate of death from COVID-19 (OR, 0.63; 95% CI, 0.58-0.69; P = .001).

A litany of other secondary variables also favored statin users, including reduced rates of discharge to hospice (OR, 0.79), ICU admission (OR, 0.69), severe acute respiratory distress syndrome (ARDs; OR, 0.72), critical ARDs (OR, 0.57), mechanical ventilation (OR, 0.60), severe sepsis with septic shock (OR, 0.66), and thrombosis (OR, 0.46). Statin users also had, on average, shorter hospital stays and briefer mechanical ventilation.

“Our study showed a strong association between preexisting statin use and reduced mortality and morbidity rates in hospitalized COVID-19 patients,” the investigators concluded. “Pleiotropic benefits of statins could be repurposed for COVID-19 illness.”

Prospective studies needed before practice changes

How to best use statins against COVID-19, if at all, remains unclear, Dr. Crimi said, as initiation upon infection has generated mixed results in other studies, possibly because of statin pharmacodynamics. Cholesterol normalization can take about 6 weeks, so other benefits may track a similar timeline.

“The delayed onset of statins’ pleiotropic effects may likely fail to keep pace with the rapidly progressive, devastating COVID-19 disease,” Dr. Crimi said. “Therefore, initiating statins for an acute disease may not be an ideal first-line treatment.”

Stronger data are on the horizon, he added, noting that 19 federally funded prospective trials are underway to better understand the relationship between statins and COVID-19.

Daniel Rader, MD, of the University of Pennsylvania, Philadelphia, said the present findings are “not especially notable” because they “mostly confirm previous studies, but in a large U.S. cohort.”

Dr. Rader, who wrote about the potential repurposing of statins for COVID-19 back in the first year of the pandemic (Cell Metab. 2020 Aug 4;32[2]:145-7), agreed with the investigators that recommending changes to clinical practice would be imprudent until randomized controlled data confirm the benefits of initiating statins in patients with active COVID-19.

“More research on the impact of cellular cholesterol metabolism on SARS-CoV-2 infection of cells and generation of inflammation would also be of interest,” he added.

The investigators disclosed no competing interests. Dr. Rader disclosed relationships with Novartis, Pfizer, Verve, and others.

Dr. Rader, who wrote about the potential repurposing of statins for COVID-19 back in the first year of the pandemic (Cell Metab. 2020 Aug 4;32[2]:145-7), agreed with the investigators that recommending changes to clinical practice would be imprudent until randomized controlled data confirm the benefits of initiating statins in patients with active COVID-19.

“More research on the impact of cellular cholesterol metabolism on SARS-CoV-2 infection of cells and generation of inflammation would also be of interest,” he added.

The investigators disclosed no competing interests. Dr. Rader disclosed relationships with Novartis, Pfizer, Verve, and others.

C. diff recurrence drops with highly targeted ridinilazole

Ridinilazole, a novel, highly specific antibiotic, was safe and showed a sustained clinical response in patients with Clostridioides difficile infection (CDI), according to phase 3 trial results presented at an annual scientific meeting on infectious diseases.

According to the Centers for Disease Control and Prevention, CDI is the top cause of antibiotic-associated diarrhea and one of the most common health care–associated infections in the United States. About 200,000 people in the United States are infected with C. difficile every year in the hospital or clinical care setting.

Most infections are currently treated with vancomycin. Although vancomycin has been shown to be more than 80% effective, it has been linked with recurrence rates ranging from 20% to 30% and interferes with the protective role of the gut microbiome against infection. The current study compared ridinilazole with vancomycin.

Results of the global, double-blinded, randomized trial were presented by Pablo C. Okhuysen, MD, professor of infectious disease at the University of Texas MD Anderson Cancer Center, Houston.

Participants with CDI received a 10-day course of ridinilazole 200 mg twice a day plus placebo or vancomycin 125 mg four times a day. The primary endpoint was sustained clinical response, defined as a clinical response with no recurrent CDI through 30 days after the end of treatment. Recurrent CDI was defined as a new episode of diarrhea with confirmed positive free toxin test requiring additional therapy.

Of the 759 patients enrolled, 745 were included in the modified intention-to-treat  population (ridinilazole, n = 370; vancomycin, n = 375). Ridinilazole achieved a numerically higher rate of sustained clinical response than vancomycin (73.0% vs. 70.7%; P = .467), although the difference was not significant. Ridinilazole also resulted in a significant reduction in recurrence rate (8.1% vs. 17.3%; P < .001).

Ridinilazole’s effect was most notable in a subgroup of patients who were not receiving other antibiotics at time of enrollment – about 70% of participants. In that subgroup, the recurrence rate was 6.7% with ridinilazole versus 16.5% with vancomycin (P < .001), Dr. Okhuysen reported.

“That resulted in a relative risk reduction of 60%,” Dr. Okhuysen told this news organization.

Dr. Okhuysen pointed out that there are currently very few treatment options for CDI other than vancomycin.

“We need new agents to treat C. difficile,” he said, “particularly for those at risk of recurrence. In our study, we found that those exposed to vancomycin had very dramatic shifts in their microbiome.”

Vancomycin depletes the gut microbiome, which decreases the conversion of primary acids to secondary bile acids, the researchers noted.

“A dysbiotic microbiome is fertile ground for C. difficile to grow,” Dr. Okhuysen said. Ridinilazole does not disrupt the microbiome, he added.

Ridinilazole was well-tolerated in the study. The proportion of patients with at least one treatment-emergent adverse effect was 36.4% versus 35.5%, respectively, in the ridinilazole and vancomycin groups. And the proportion who stopped treatment because of treatment-related side effects was 0.8% versus 2.9%.

Mary Hayden, MD, pathology director in the division of infectious diseases at Rush University Medical Center, Chicago, who was not involved with the study, said the results are encouraging as “alternative agents or strategies to prevent recurrence are important to reduce CDI morbidity.”

Its double-blind, randomized, multicenter design strengthens the findings, she explained, adding that “the secondary outcomes of higher concentrations of secondary bile acids and microbiota diversity and composition lend biological plausibility.”

Ridinilazole’s narrow spectrum of activity “should result in less disruption of the colonic microbiota, which has theoretical benefit for both reducing CDI recurrence and for reducing risk of acquisition of multidrug-resistant organisms,” Dr. Hayden said.

Dr. Okhuysen shared that the team is in talks with the Food and Drug Administration and is preparing a manuscript for publication.

The study was supported by Summit Pharmaceuticals and funded by the Biomedical and Advanced Research and Development Authority. Dr. Okhuysen has reported receiving research support from and/or consulting for Summit, Merck, Deinove, Melinta, and Ferring Pharmaceuticals. Some of the coauthors have financial relationships with or received research support from Summit. Dr. Hayden has reported no relevant financial relationships.

Ten-day methotrexate pause after COVID vaccine booster enhances immunity against Omicron variant

Article Type

Tue, 02/07/2023 - 16:38

People taking methotrexate for immunomodulatory diseases can skip one or two scheduled doses after they get an mRNA-based vaccine booster for COVID-19 and achieve a level of immunity against Omicron variants that’s comparable to people who aren’t immunosuppressed, a small observational cohort study from Germany reported.

“In general, the data suggest that pausing methotrexate is feasible, and it’s sufficient if the last dose occurs 1-3 days before the vaccination,” study coauthor Gerd Burmester, MD, a senior professor of rheumatology and immunology at the University of Medicine Berlin, told this news organization. “In pragmatic terms: pausing the methotrexate injection just twice after the vaccine is finished and, interestingly, not prior to the vaccination.”

Dr. Gerd Burmester


The study, published online in RMD Open, included a statistical analysis that determined that a 10-day pause after the vaccination would be optimal, Dr. Burmester said.

Dr. Burmester and coauthors claimed this is the first study to evaluate the antibody response in patients on methotrexate against Omicron variants – in this study, variants BA.1 and BA.2 – after getting a COVID-19 mRNA booster. The study compared neutralizing serum activity of 50 patients taking methotrexate – 24 of whom continued treatments uninterrupted and 26 of whom paused treatments after getting a second booster – with 25 nonimmunosuppressed patients who served as controls. A total of 24% of the patients taking methotrexate received the mRNA-1273 vaccine while the entire control group received the Pfizer/BioNTech BNT162b2 vaccine.

The researchers used SARS-CoV-2 pseudovirus neutralization assays to evaluate post-vaccination antibody levels.

The U.S. Centers for Disease Control and Prevention and other government health agencies have recommended that immunocompromised patients get a fourth COVID-19 vaccination. But these vaccines can be problematic in patients taking methotrexate, which was linked to a reduced response after the second and third doses of the COVID-19 vaccine.

Previous studies reported that pausing methotrexate for 10 or 14 days after the first two vaccinations improved the production of neutralizing antibodies. A 2022 study found that a 2-week pause after a booster increased antibody response against S1 RBD (receptor binding domain) of the SARS-CoV-2 spike protein about twofold. Another recently published study of mRNA vaccines found that taking methotrexate with either a biologic or targeted synthetic disease-modifying antirheumatic drug reduces the efficacy of a third (booster) shot of SARS-CoV-2 mRNA vaccine in older adults but not younger patients with RA.

“Our study and also the other studies suggested that you can pause methotrexate treatment safely from a point of view of disease activity of rheumatoid arthritis,” Dr. Burmester said. “If you do the pause just twice or once only, it doesn’t lead to significant flares.”
 

Study results

The study found that serum neutralizing activity against the Omicron BA.1 variant, measured as geometric mean 50% inhibitory serum dilution (ID50s), wasn’t significantly different between the methotrexate and the nonimmunosuppressed groups before getting their mRNA booster (P = .657). However, 4 weeks after getting the booster, the nonimmunosuppressed group had a 68-fold increase in antibody activity versus a 20-fold increase in the methotrexate patients. After 12 weeks, ID50s in both groups decreased by about half (P = .001).

 

 

The methotrexate patients who continued therapy after the booster had significantly lower neutralization against Omicron BA.1 at both 4 weeks and 12 weeks than did their counterparts who paused therapy, as well as control patients.

The results were very similar in the same group comparisons of the serum neutralizing activity against the Omicron BA.2 variant at 4 and 12 weeks after booster vaccination.
 

Expert commentary

This study is noteworthy because it used SARS-CoV-2 pseudovirus neutralization assays to evaluate antibody levels, Kevin Winthrop, MD, MPH, professor of infectious disease and public health at Oregon Health & Science University, Portland, who was not involved in the study, said. “A lot of studies don’t look at neutralizing antibody titers, and that’s really what we care about,” Dr. Winthrop said. “What we want are functional antibodies that are doing something, and the only way to do that is to test them.”

Dr. Kevin Winthrop

The study is “confirmatory” of other studies that call for pausing methotrexate after vaccination, Dr. Winthrop said, including a study he coauthored, and which the German researchers cited, that found pausing methotrexate for a week or so after the influenza vaccination in RA patients improved vaccine immunogenicity. He added that the findings with the early Omicron variants are important because the newest boosters target the later Omicron variants, BA.4 and BA.5.

“The bottom line is that when someone comes in for a COVID-19 vaccination, tell them to be off of methotrexate for 7-10 days,” Dr. Winthrop said. “This is for the booster, but it raises the question: If you go out to three, four, or five vaccinations, does this matter anymore? With the flu vaccine, most people are out to 10 or 15 boosters, and we haven’t seen any significant increase in disease flares.”

The study received funding from Medac, Gilead/Galapagos, and Friends and Sponsors of Berlin Charity. Dr. Burmester reported no relevant disclosures. Dr. Winthrop is a research consultant to Pfizer.

Why the 5-day isolation period for COVID makes no sense

Article Type
Changed
Thu, 10/20/2022 - 15:02

 

Welcome to Impact Factor, your weekly dose of commentary on a new medical study. I’m Dr. F. Perry Wilson of the Yale School of Medicine.

One of the more baffling decisions the CDC made during this pandemic was when they reduced the duration of isolation after a positive COVID test from 10 days to 5 days and did not require a negative antigen test to end isolation.



Multiple studies had suggested, after all, that positive antigen tests, while not perfect, were a decent proxy for infectivity. And if the purpose of isolation is to keep other community members safe, why not use a readily available test to know when it might be safe to go out in public again?

Also, 5 days just wasn’t that much time. Many individuals are symptomatic long after that point. Many people test positive long after that point. What exactly is the point of the 5-day isolation period?

We got some hard numbers this week to show just how good (or bad) an arbitrary-seeming 5-day isolation period is, thanks to this study from JAMA Network Open, which gives us a low-end estimate for the proportion of people who remain positive on antigen tests, which is to say infectious, after an isolation period.

This study estimates the low end of postisolation infectivity because of the study population: student athletes at an NCAA Division I school, which may or may not be Stanford. These athletes tested positive for COVID after having at least one dose of vaccine from January to May 2022. School protocol was to put the students in isolation for 7 days, at which time they could “test out” with a negative antigen test.

Put simply, these were healthy people. They were young. They were athletes. They were vaccinated. If anyone is going to have a brief, easy COVID course, it would be them. And they are doing at least a week of isolation, not 5 days.



So – isolation for 7 days. Antigen testing on day 7. How many still tested positive? Of 248 individuals tested, 67 (27%) tested positive. One in four.

More than half of those positive on day 7 tested positive on day 8, and more than half of those tested positive again on day 9. By day 10, they were released from isolation without further testing.

So, right there we have confirmation that 5 days of isolation without a negative test means you’re releasing a decent percentage of infectious individuals back into the population.

There were some predictors of prolonged positivity.



Symptomatic athletes were much more likely to test positive than asymptomatic athletes.

And the particular variant seemed to matter as well. In this time period, BA.1 and BA.2 were dominant, and it was pretty clear that BA.2 persisted longer than BA.1.

This brings me back to my original question: What is the point of the 5-day isolation period? On the basis of this study, you could imagine a guideline based on symptoms: Stay home until you feel better. You could imagine a guideline based on testing: Stay home until you test negative. A guideline based on time alone just doesn’t comport with the data. The benefit of policies based on symptoms or testing are obvious; some people would be out of isolation even before 5 days. But the downside, of course, is that some people would be stuck in isolation for much longer.

Maybe we should just say it. At this point, you could even imagine there being no recommendation at all – no isolation period. Like, you just stay home if you feel like you should stay home. I’m not entirely sure that such a policy would necessarily result in a greater number of infectious people out in the community.

In any case, as the arbitrariness of this particular 5-day isolation policy becomes more clear, the policy itself may be living on borrowed time.

Vaccine adherence hinges on improving science communication

Article Type
Changed
Thu, 12/15/2022 - 14:24

 

I’m not getting the vaccine. Nobody knows the long-term effects, and I heard that people are getting clots.”

We were screening patients at a low-cost clinic in Philadelphia for concerns surrounding social determinants of health. During one patient visit, in addition to concerns including housing, medication affordability, and transportation, we found that she had not received the COVID-19 vaccine, and we asked if she was interested in being immunized.

News reports have endlessly covered antivaccine sentiment, but this personal encounter hit home. From simple face masks to groundbreaking vaccines, we failed as physicians to encourage widespread uptake of health-protective measures despite strong scientific backing.

Large swaths of the public deny these tools’ importance or question their safety. This is ultimately rooted in the inability of community leaders and health care professionals to communicate with the public.

Science communication is inherently difficult. Scientists use complex language, and it is hard to evaluate the lay public’s baseline knowledge. Moreover, we are trained to speak with qualifications, encourage doubt, and accept change and evolution of fact. These qualities contrast the definitive messaging necessary in public settings. COVID-19 highlighted these gaps, where regardless of novel scientific solutions, poor communication led to a resistance to accept the tested scientific solution, which ultimately was the rate-limiting factor for overcoming the virus.

As directors of Physician Executive Leadership, an organization that trains future physicians at Thomas Jefferson University to tackle emerging health care issues, we hosted Paul Offit, MD, a national media figure and vaccine advocate. Dr. Offit shared his personal growth during the pandemic, from being abruptly thrown into the spotlight to eventually honing his communication skills. Dr. Offit discussed the challenges of sharing medical knowledge with laypeople and adaptations that are necessary. We found this transformative, realizing the importance of science communication training early in medical education.

Emphasizing the humanities and building soft skills will improve outcomes and benefit broader society by producing physician-leaders in public health and policy. We hope to improve our own communication skills and work in medical education to incorporate similar training into education paradigms for future students.

As seen in our patient interaction, strong science alone will not drive patient adherence; instead, we must work at personal and system levels to induce change. Physicians have a unique opportunity to generate trust and guide evidence-based policy. We must communicate, whether one-on-one with patients, or to millions of viewers via media or policymaker settings. We hope to not only be doctors, but to be advocates, leaders, and trusted advisers for the public.

Iron deficiency may protect against bacterial pneumonia

Article Type
Changed
Fri, 10/21/2022 - 08:18

 

Patients with iron deficiency anemia who developed bacterial pneumonia showed improved outcomes compared to those without iron deficiency anemia, based on data from more than 450,000 individuals in the National Inpatient Sample.

Iron deficiency is the most common nutritional deficiency worldwide, and can lead to anemia, but iron also has been identified as essential to the survival and growth of pathogenic organisms, Mubarak Yusuf, MD, said in a presentation at the annual meeting of the American College of Chest Physicians (CHEST).

However, the specific impact of iron deficiency anemia (IDA) on outcomes in patients hospitalized with acute bacterial infections has not been explored, said Dr. Yusuf, a third-year internal medicine resident at Lincoln Medical Center in New York.

In the study, Dr. Yusuf and colleagues reviewed data from the Nationwide Inpatient Sample (NIS) Database for 2016-2019. They identified 452,040 adults aged 18 or older with a primary diagnosis of bacterial pneumonia based on ICD-10 codes. Patients with a principal diagnosis other than bacterial pneumonia were excluded.

Of these, 5.5% had a secondary diagnosis of IDA. The mean age of the study population was similar between the IDA and non-IDA groups (68 years) and racial distribution was similar, with a White majority of approximately 77%. Slightly more patients in the IDA group were women (58.5% vs. 51.6%) and this difference was statistically significant (P < .00001). Most of the patients (94.6%) in the IDA group had at least three comorbidities, as did 78.1% of the non-IDA group.

The primary outcome was mortality, and the overall mortality in the study population was 2.89%. Although the mortality percentage was higher in the IDA group compared to the non-IDA group (3.25% vs. 2.87%), “when we adjusted for confounders, we noticed a decreased odds of mortality in the IDA group” with an adjusted odds ratio of 0.74 (P = .001), Dr. Yusuf said.

In addition, secondary outcomes of septic shock, acute respiratory failure, and cardiac arrest were lower in the IDA group in a regression analysis, with adjusted odds ratios of 0.71, 0.78, and 0.57, respectively.

The mean length of stay was 0.3 days higher in the IDA group, and the researchers found a nonsignificant increase in total hospital costs of $402.5 for IDA patients compared to those without IDA, said Dr. Yusuf.

The take-home message from the study is actually a question to the clinician, Dr. Yusuf said. “Should you consider a delay in treatment [of iron deficiency anemia] if the patient is not symptomatic?” he asked.

More research is needed to investigate the improved outcomes in the iron deficient population, but the large sample size supports an association that is worth exploring, he concluded.

“The findings of this research may suggest a protective effect of iron deficiency in acute bacterial pneumonia,” Dr. Yusuf said in a press release accompanying the meeting presentation. “More research is needed to elucidate the improved outcomes found in this population, but this research may lead clinicians to consider a delay in treatment of nonsymptomatic iron deficiency in acute bacterial infection,” he added.

The study received no outside funding. The researchers had no financial conflicts to disclose.

Reminder that COVID-19 and cancer can be a deadly combo

Article Type
Changed
Thu, 12/15/2022 - 17:16

A new study underscores the importance of COVID-19 and regular COVID-19 testing among adults with a recent cancer diagnosis.

The Indiana statewide study, conducted at the beginning of the pandemic, found that unvaccinated adults with cancer and SARS-CoV-2 infection were nearly seven times more likely to die from any cause than uninfected adults with cancer.

“This analysis provides additional empirical evidence on the magnitude of risk to patients with cancer whose immune systems are often weakened either by the disease or treatment,” the study team wrote.

The study was published online in JMIR Cancer.

Although evidence has consistently revealed similar findings, the risk of death among unvaccinated people with cancer and COVID-19 has not been nearly as high in previous studies, lead author Brian E. Dixon, PhD, MBA, with Indiana University Richard M. Fairbanks School of Public Health, Indianapolis, said in a statement. Previous studies from China, for instance, reported a two- to threefold greater risk of all-cause mortality among unvaccinated adults with cancer and COVID-19.

A potential reason for this discrepancy, Dr. Dixon noted, is that earlier studies were “generally smaller and made calculations based on data from a single cancer center or health system.”

Another reason is testing for COVID-19 early in the pandemic was limited to symptomatic individuals who may have had more severe infections, possibly leading to an overestimate of the association between SARS-CoV-2 infection, cancer, and all-cause mortality.

In the current analysis, researchers used electronic health records linked to Indiana’s statewide SARS-CoV-2 testing database and state vital records to evaluate the association between SARS-CoV-2 infection and all-cause mortality among 41,924 adults newly diagnosed with cancer between Jan. 1, 2019, and Dec. 31, 2020.

Most people with cancer were White (78.4%) and about half were male. At the time of diagnosis, 17% had one comorbid condition and about 10% had two or more. Most patients had breast cancer (14%), prostate cancer (13%), or melanoma (13%).

During the study period, 2,894 patients (7%) tested positive for SARS-CoV-2.

In multivariate adjusted analysis, the risk of death among those newly diagnosed with cancer increased by 91% (adjusted hazard ratio, 1.91) during the first year of the pandemic before vaccines were available, compared with the year before (January 2019 to Jan. 14, 2020).

During the pandemic period, the risk of death was roughly threefold higher among adults 65 years old and older, compared with adults 18-44 years old (aHR, 3.35).

When looking at the time from a cancer diagnosis to SARS-CoV-2 infection, infection was associated with an almost sevenfold increase in all-cause mortality (aHR, 6.91). Adults 65 years old and older had an almost threefold increased risk of dying, compared with their younger peers (aHR, 2.74).

Dr. Dixon and colleagues also observed an increased risk of death in men with cancer and COVID, compared with women (aHR, 1.23) and those with at least two comorbid conditions versus none (aHR, 2.12). In addition, the risk of dying was 9% higher among Indiana’s rural population than urban dwellers.

Compared with other cancer types, individuals with lung cancer and other digestive cancers had the highest risk of death after SARS-CoV-2 infection (aHR, 1.45 and 1.80, respectively).

“Our findings highlight the increased risk of death for adult cancer patients who test positive for COVID and underscore the importance to cancer patients – including those in remission – of vaccinations, boosters, and regular COVID testing,” Dr. Dixon commented.

“Our results should encourage individuals diagnosed with cancer not only to take preventive action, but also to expeditiously seek out treatments available in the marketplace should they test positive for COVID,” he added.

Support for the study was provided by Indiana University Simon Cancer Center and the Centers for Disease Control and Prevention. The authors have disclosed no relevant financial relationships.

A new study underscores the importance of COVID-19 and regular COVID-19 testing among adults with a recent cancer diagnosis.

The Indiana statewide study, conducted at the beginning of the pandemic, found that unvaccinated adults with cancer and SARS-CoV-2 infection were nearly seven times more likely to die from any cause than uninfected adults with cancer.

“This analysis provides additional empirical evidence on the magnitude of risk to patients with cancer whose immune systems are often weakened either by the disease or treatment,” the study team wrote.

The study was published online in JMIR Cancer.

Although evidence has consistently revealed similar findings, the risk of death among unvaccinated people with cancer and COVID-19 has not been nearly as high in previous studies, lead author Brian E. Dixon, PhD, MBA, with Indiana University Richard M. Fairbanks School of Public Health, Indianapolis, said in a statement. Previous studies from China, for instance, reported a two- to threefold greater risk of all-cause mortality among unvaccinated adults with cancer and COVID-19.

A potential reason for this discrepancy, Dr. Dixon noted, is that earlier studies were “generally smaller and made calculations based on data from a single cancer center or health system.”

Another reason is testing for COVID-19 early in the pandemic was limited to symptomatic individuals who may have had more severe infections, possibly leading to an overestimate of the association between SARS-CoV-2 infection, cancer, and all-cause mortality.

In the current analysis, researchers used electronic health records linked to Indiana’s statewide SARS-CoV-2 testing database and state vital records to evaluate the association between SARS-CoV-2 infection and all-cause mortality among 41,924 adults newly diagnosed with cancer between Jan. 1, 2019, and Dec. 31, 2020.

Most people with cancer were White (78.4%) and about half were male. At the time of diagnosis, 17% had one comorbid condition and about 10% had two or more. Most patients had breast cancer (14%), prostate cancer (13%), or melanoma (13%).

During the study period, 2,894 patients (7%) tested positive for SARS-CoV-2.

In multivariate adjusted analysis, the risk of death among those newly diagnosed with cancer increased by 91% (adjusted hazard ratio, 1.91) during the first year of the pandemic before vaccines were available, compared with the year before (January 2019 to Jan. 14, 2020).

Tumor vs. saxophone: The surgical grudge match

Brain surgery is a notoriously difficult task. There’s a reason we say, “Well, at least it’s not brain surgery” when we’re trying to convince someone that a task isn’t that tough. Make one wrong incision, cut the wrong neuron, and it’s goodbye higher cognitive function. And most people appreciate thinking. Crazy, right?

One would imagine that the act of brain surgery would become even more difficult when the patient brings his saxophone and plays it randomly throughout the operation. It’s a hospital, after all, not a jazz club. Patients don’t get to play musical instruments during other surgeries. Why should brain surgery patients get special treatment?

Paideia International Hospital

As it turns out, the musical performance was actually quite helpful. A man in Italy had a brain tumor in a particularly complex area, and he’s left-handed, which apparently makes the brain’s neural pathways much more complicated. Plus, he insisted that he retain his musical ability after the surgery. So he and his medical team had a crazy thought: Why not play the saxophone throughout the surgery? After all, according to head surgeon Christian Brogna, MD, playing an instrument means you understand music, which tests many higher cognitive functions such as coordination, mathematics, and memory.

And so, at various points throughout the 9-hour surgery, the patient played his saxophone for his doctors. Doing so allowed the surgeons to map the patient’s brain in a more complete and personalized fashion. With that extra knowledge, they were able to successfully remove the tumor while maintaining the patient’s musical ability, and the patient was discharged on Oct. 13, just 3 days after his operation.

While we’re happy the patient recovered, we do have to question his choice of music. During the surgery, he played the theme to the 1970 movie “Love Story” and the Italian national anthem. Perfectly fine pieces, no doubt, but the saxophone solo in “Jungleland” exists. And we could listen to that for 9 hours straight. In fact, we do that every Friday in the LOTME office.
 

Basketball has the Big Dance. Mosquitoes get the Big Sniff

In this week’s installment of our seemingly never-ending series, “Mosquitoes and the scientists who love them,” we visit The Rockefeller University in New York, where the olfactory capabilities of Aedes Aegypti – the primary vector species for Zika, dengue, yellow fever, and chikungunya – became the subject of a round robin–style tournament.

First things first, though. If you’re going to test mosquito noses, you have to give them something to smell. The researchers enrolled eight humans who were willing to wear nylon stockings on their forearms for 6 hours a day for multiple days. “Over the next few years, the researchers tested the nylons against each other in all possible pairings,” Leslie B. Vosshall, PhD, and associates said in a statement from the university. In other words, mosquito March Madness.

Nylons from different participants were hooked up in pairs to an olfactometer assay consisting of a plexiglass chamber divided into two tubes, each ending in a box that held a stocking. The mosquitoes were placed in the main chamber and observed as they flew down the tubes toward one stocking or the other.

Eventually, the “winner” of the “tournament” was Subject 33. And no, we don’t know why there was a Subject 33 since the study involved only eight participants. We do know that the nylons worn by Subject 33 were “four times more attractive to the mosquitoes than the next most-attractive study participant, and an astonishing 100 times more appealing than the least attractive, Subject 19,” according to the written statement.

Chemical analysis identified 50 molecular compounds that were elevated in the sebum of the high-attracting participants, and eventually the investigators discovered that mosquito magnets produced carboxylic acids at much higher levels than the less-attractive volunteers.

We could go on about the research team genetically engineering mosquitoes without odor receptors, but we have to save something for later. Tune in again next week for another exciting episode of “Mosquitoes and the scientists who love them.”
 

 

 

Are women better with words?

Men vs. Women is probably the oldest argument in the book, but there may now be movement. Researchers have been able not only to shift the advantage toward women, but also to use that knowledge to medical advantage.

When it comes to the matter of words and remembering them, women apparently have men beat. The margin is small, said lead author Marco Hirnstein, PhD, of the University of Bergen, Norway, but, after performing a meta-analysis of 168 published studies and PhD theses involving more than 350,000 participants, it’s pretty clear. The research supports women’s advantage over men in recall, verbal fluency (categorical and phonemic), and recognition.

So how is this information useful from a medical standpoint?

Dr. Hirnstein and colleagues suggested that this information can help in interpreting diagnostic assessment results. The example given was dementia diagnosis. Since women are underdiagnosed because their baseline exceeds average while men are overdiagnosed, taking gender and performance into account could clear up or catch cases that might otherwise slip through the cracks.

Now, let’s just put this part of the debate to rest and take this not only as a win for women but for science as well.

People of color more likely to be hospitalized for influenza, CDC report finds

Article Type

Thu, 10/20/2022 - 09:40

Black Americans are 80% more likely to be hospitalized for the flu, compared with White Americans, according to new federal data.

Black, Hispanic, and American Indian/Alaska Native (AI/AN) adults in the United States also have had lower influenza vaccination rates, compared with their White counterparts, since 2010, researchers at the Centers for Disease Control and Prevention (CDC) revealed in a report.

The inequalities are the result of barriers to care, distrust of the medical system, and misinformation, the report said.

“We have many of the tools we need to address inequities and flu vaccination coverage and outcomes,” said CDC Acting Principal Deputy Director Debra Houry, MD, MPH, in a press call; “however, we must acknowledge that inequities in access to care continue to exist. To improve vaccine uptake, we must address the root causes of these ongoing disparities.”

The CDC has already reported early increases in flu activity in the United States, with the highest activity in the southeastern and south-central parts of the country. Experts also warn of a potentially more severe influenza season than in the previous 2 years. CDC officials emphasized that vaccination is the best protection against severe illness, hospitalization, and death from the flu. “Everyone should get vaccinated against flu today and encourage others and their community to get a flu vaccine for the best protection against flu this fall and winter,” Dr. Houry said.

In the recent report on disparities by community published October 18 in CDC Vital Signs, researchers looked at hospitalization rates from 2009 to 2022 and vaccination rates from 2010 to 2022 based on race and ethnicity using two national databases, the Influenza-Associated Hospitalization Surveillance Network and the Behavioral Risk Factor Surveillance System. All individuals included in the analysis were aged 18 years or older, and the 2020-2021 flu season was excluded from the analysis because of insufficient data.

Compared with those for White adults, hospitalization rates were 80% higher for Black adults, 30% higher for Hispanic adults, and 20% higher for AI/AN adults. While flu vaccination rates were similar in White and Asian adults (about 54%), coverage was lower in Black (42%), Hispanic (38%), AI/AN (41%), and other/multiracial (43%) adults. This disparity persisted even among individuals who had medical insurance, a personal health care provider, and a routine checkup within the last year.

“This report adds to the body of evidence that shows people from certain racial and ethnic minority groups have more severe outcomes at higher rates than White adults,” Carla Black, PhD, MPH, an epidemiologist at the CDC’s Immunization Services Division, said during the press call. While flu vaccines may not always prevent infection, people who do get sick after being vaccinated tend to have better outcomes, she added. The report noted that building trust, increasing access to vaccination services, and combating misinformation are important steps to increasing vaccine coverage in minority groups. 

While social distancing measures such as masking have made it difficult for the flu to spread, the relaxation of these safety measures could also lead to higher case counts. “We’ve had two mild flu seasons, and this means we might be ripe for a severe season,” Dr. Black said. “People haven’t had natural disease in 2 years, so there’s less natural immunity out there. People are going back to work. People are traveling again. All of these factors could contribute to us having a more severe flu season.”

CDC officials emphasized that vaccination is the best protection against severe illness, hospitalization, and death from the flu. “Everyone should get vaccinated against flu today and encourage others and their community to get a flu vaccine for the best protection against flu this fall and winter,” Dr. Houry said.

In the recent report on disparities by community published October 18 in CDC Vital Signs, researchers looked at hospitalization rates from 2009 to 2022 and vaccination rates from 2010 to 2022 based on race and ethnicity using two national databases, the Influenza-Associated Hospitalization Surveillance Network and the Behavioral Risk Factor Surveillance System. All individuals included in the analysis were aged 18 years or older, and the 2020-2021 flu season was excluded from the analysis because of insufficient data.

Compared with those for White adults, hospitalization rates were 80% higher for Black adults, 30% higher for Hispanic adults, and 20% higher for AI/AN adults. While flu vaccination rates were similar in White and Asian adults (about 54%), coverage was lower in Black (42%), Hispanic (38%), AI/AN (41%), and other/multiracial (43%) adults. This disparity persisted even among individuals who had medical insurance, a personal health care provider, and a routine checkup within the last year.

“This report adds to the body of evidence that shows people from certain racial and ethnic minority groups have more severe outcomes at higher rates than White adults,” Carla Black, PhD, MPH, an epidemiologist at the CDC’s Immunization Services Division, said during the press call. While flu vaccines may not always prevent infection, people who do get sick after being vaccinated tend to have better outcomes, she added. The report noted that building trust, increasing access to vaccination services, and combating misinformation are important steps to increasing vaccine coverage in minority groups. 

While social distancing measures such as masking have made it difficult for the flu to spread, the relaxation of these safety measures could also lead to higher case counts. “We’ve had two mild flu seasons, and this means we might be ripe for a severe season,” Dr. Black said. “People haven’t had natural disease in 2 years, so there’s less natural immunity out there. People are going back to work. People are traveling again. All of these factors could contribute to us having a more severe flu season.”
