New research suggests that the casirivimab-imdevimab monoclonal antibody treatment for COVID-19 could have been delivered via injection instead of intravenously. There was no statistically significant difference in 28-day hospitalization or death in those treated intravenously and via subcutaneous injection.

The findings, published in JAMA Network Open, aren’t directly relevant at the moment, since the casirivimab-imdevimab treatment was abandoned when it failed to work during the Omicron outbreak. However, they point toward the importance of studying multiple routes of administration, said study lead author and pharmacist Erin K. McCreary, PharmD, of the University of Pittsburgh, in an interview.

“It would be beneficial for all future monoclonal antibodies for COVID-19 to be studied subcutaneously or intramuscularly, if possible, since that’s logistically easier than IV in the outpatient setting,” she said.

According to Dr. McCreary, an outpatient casirivimab-imdevimab treatment was used from 2020 to 2022 to treat higher-risk patients with mild to moderate COVID-19. The treatment was typically given intravenously as recommended by the federal government’s Emergency Use Authorization, she said. Clinical trials of the treatment, according to the study, allowed only IV administration.

“However, during the Delta surge, we were faced with so many patient referrals for treatment and staffing shortages that we couldn’t accommodate every patient unless we switched to [the] subcutaneous route,” Dr. McCreary said. This approach shortened appointment times by 30 minutes vs. infusion, she said.

There are many benefits to subcutaneous administration versus IV, Dr. McCreary said. “You don’t need to start an intravenous line, so you avoid the line kit and the nursing time needed for that. You draw up the drug directly into syringes and inject under the skin, so you avoid the need for a fluid bag to mix the drug in and run intravenously,” she said. “The appointment times are shorter, so you can accommodate more patients per day. Pharmacy interns can give subcutaneous injections, so you avoid the need for a nurse trained in placing intravenous lines.”

The researchers prospectively assigned 1,959 matched adults with mild to moderate COVID-19 to subcutaneous or intravenous treatment. Of 969 patients who received the subcutaneous treatment (mean age, 53.8; 56.4% women), the 28-day rate of hospitalization or death was 3.4%. Of 1,216 patients who received intravenous treatment (mean age, 54.3; 54.4% women), the rate was 1.7%. The difference was not statistically significant (P = .16).

Among 1,306 nontreated controls, 7.0% were hospitalized or died within 28 days (risk ratio = 0.48 vs. subcutaneous treatment group; 95% confidence interval, 0.30-0.80; P = .002).

“We did not find any patients where IV is a must,” Dr. McCreary said. “However, our study wasn’t powered to see a difference in certain subgroups.”

In an interview, University of Toronto internal medicine and pharmacology/toxicology physician Peter Wu, MD, said he agrees that the study has value because it emphasizes the importance of testing whether monoclonal antibodies can be administered in ways other than intravenously.

However, in the larger picture, he said, this may be irrelevant since it’s clear that anti-spike treatments are not holding up against COVID-19 variants.

No study funding is reported. Some study authors reported disclosures outside the submitted work. Dr. Wu has disclosed no relevant financial relationships.

Who needs medical degrees anyway?

It’s no secret that doctors make a fair chunk of change. It’s a lucrative profession, but that big fat paycheck is siloed behind long, tough years of medical school and residency. It’s not an easy path doctors walk. Or at least, it’s not supposed to be. Anything’s easy if you’re willing to lie.

That brings us to Sonia, a 31-year-old woman from northern France with a bachelor’s degree in real estate management who wasn’t bringing in enough money for her three children, at least not to her satisfaction. Naturally, the only decision was to forge some diplomas from the University of Strasbourg, as well as a certificate from the French Order of Physicians. Sonia got hired as a general practitioner by using the identities of two doctors who shared her name. She had no experience, had no idea what she was doing, and was wearing a GPS tagging bracelet for an unrelated crime, so she was quickly caught and exposed in October 2021, after, um, 3 years of fake doctoring, according to France Live.

Not to be deterred by this temporary setback, Sonia proceeded to immediately find work as an ophthalmologist, a career that requires more than 10 years of training, continuing her fraudulent medical career until recently, when she was caught again and sentenced to 3 years in prison. She did make 70,000 euros a year as a fake doctor, which isn’t exactly huge money, but certainly not bad either.

We certainly hope she’s learned her lesson about impersonating a doctor, at this point, but maybe she should just go to medical school. If not, northern France might just end up with a new endocrinologist or oncologist floating around in 3 years.
 

No need to ‘guess what size horse you are’

Is COVID-19 warming up for yet another surge? Maybe. That means it’s also time for the return of its remora-like follower, ivermectin. Our thanks go out to the Tennessee state legislature for bringing the proven-to-be-ineffective treatment for COVID back into our hearts and minds and emergency rooms.

Both the state House and Senate have approved a bill that allows pharmacists to dispense the antiparasitic drug without a prescription while shielding them “from any liability that could arise from dispensing ivermectin,” Nashville Public Radio reported.

The drug’s manufacturer, Merck, said over a year ago that there is “no scientific basis for a potential therapeutic effect against COVID-19 from preclinical studies … and a concerning lack of safety data.” More recently, a study published in the New England Journal of Medicine showed that ivermectin treatment had no important benefits in patients with COVID.

Last week, the bill’s Senate sponsor, Frank Niceley of Strawberry Plains, said that it was all about safety, as he explained to NPR station WPLN: “It’s a lot safer to go to your pharmacist and let him tell you how much ivermectin to take than it is to go to the co-op and guess what size horse you are.”

And on that note, here are a few more items of business that just might end up on the legislature’s calendar:

• Horses will be allowed to “share” their unused ivermectin with humans and other mammals.
• An apple a day not only keeps the doctor away, but the IRS and the FDA as well.
• Colon cleansing is more fun than humans should be allowed to have.
• TikTok videos qualify as CME.

Speak louder, I can’t see you

With the introduction of FaceTime and the pandemic pushing work and social events to Zoom, video calls have become ubiquitous. Along the way, however, we’ve had to learn to adjust to technical difficulties. Often by yelling at the screen when the video quality is disrupted. Waving our hands and arms, speaking louder. Sound like you?

Tumisu/Pixabay

Well, a new study published in Royal Society Open Science shows that it sounds like a lot of us.

James Trujillo of the Max Planck Institute for Psycholinguistics in Nijmegen, the Netherlands, who was lead author of the paper, said on Eurekalert that “previous research has shown that speech and gestures are linked, but ours is the first to look into how visuals impact our behavior in those fields.”

He and his associates set up 40 participants in separate rooms to have conversations in pairs over a video chat. Over the course of 40 minutes, the video quality started to deteriorate from clear to extremely blurry. When the video quality was affected, participants started with gestures but as the quality continued to lessen the gestures increased and so did the decibels of their voices.

Even when the participants could barely see each other, they still gestured and their voices were even louder, positively supporting the idea that gestures and speech are a dynamically linked when it comes to communication. Even on regular phone calls, when we can’t see each other at all, people make small movements and gestures, Mr. Trujillo said.

So, the next time the Wifi is terrible and your video calls keep cutting out, don’t worry about looking foolish screaming at the computer. We’ve all been there.
 

Seek a doctor if standing at attention for more than 4 hours

Imbrochável. In Brazil, it means “unfloppable” or “flaccid proof.” It’s also a word that Brazilian president Jair Bolsonaro likes to use when referring to himself. Gives you a good idea of what he’s all about. Imagine his embarrassment when news recently broke about more than 30,000 pills of Viagra that had been secretly distributed to the Brazilian military.

PublicDomainPictures/Pixabay

The military offered a simple and plausible explanation: The Viagra had been prescribed to treat pulmonary hypertension. Fair, but when a Brazilian newspaper dug a little deeper, they found that this was not the case. The Viagra was, in general, being used for its, shall we say, traditional purpose.

Many Brazilians reacted poorly to the news that their tax dollars were being used to provide Brazilian soldiers with downstairs assistance, with the standard associated furor on social media. A rival politician, Ciro Gomes, who is planning on challenging the president in an upcoming election, had perhaps the best remark on the situation: “Unless they’re able to prove they’re developing some kind of secret weapon – capable of revolutionizing the international arms industry – it’ll be tough to justify the purchase of 35,000 units of a erectile dysfunction drug.”

Hmm, secret weapon. Well, a certain Russian fellow has made a bit of a thrust into world affairs recently. Does anyone know if Putin is sitting on a big Viagra stash?

Hmm, secret weapon. Well, a certain Russian fellow has made a bit of a thrust into world affairs recently. Does anyone know if Putin is sitting on a big Viagra stash?
 

Jo Ward’s twin boys have been to the emergency department for respiratory problems about as many times as the dozen years they’ve been alive. Both have asthma and bronchopulmonary dysplasia, a form of chronic airway damage that can occur in children born premature, as the twins were. But each time Ms. Ward took them in for treatment during an acute bout of breathing distress, the staff told her to schedule a follow-up visit for the children with their physician only if they didn’t get better, not regardless of the outcome – as medical guidelines recommend.

“They asked questions, they did the exams, but they really didn’t give you a lot of information to help you at home,” Ms. Ward told this news organization. If they had, she doesn’t think she’d have needed to take them in for emergency care so often.

A new study, published in Academic Pediatrics, suggests she’s right.

Current clinical guidelines for asthma recommend that patients who visit the ED for an asthma-related problem should have a follow-up appointment within a month after the visit, independent of how well they have recovered once home, according to Naomi S. Bardach, MD, a professor of pediatrics and health policy at the University of California, San Francisco, who led the new study.

Her research found that children who have a follow-up appointment within 2 weeks of such a visit are less likely to come back again the next year. Yet the study also found that only about one in five youth had a follow-up visit within that 2-week window.

“The emergency department visit is probably a sign that they need some additional attention for their asthma,” Dr. Bardach said. “We know we can prevent emergency department visits if they get the right kind of medication or if they figure out how to avoid the things that are going to cause an asthma exacerbation or flare.”

For the study, Dr. Bardach and colleagues analyzed data from California, Vermont, and Massachusetts for all asthma-related emergency visits for patients aged 3-21 years between 2013 and 2016.

Out of the 90,267 such visits they identified, 22.6% of patients had a follow-up within 2 weeks, more often by patients who were younger, had commercial insurance, had evidence of prior asthma, or had complex chronic conditions.

Whereas 5.7% of patients who had follow-up visits returned to the ED within 60 days, 6.4% of those who didn’t came back – a 12% difference (P < .001). The gap was larger a year out, with 25% of those with follow-ups returning to the ED, compared with 28.3% of those without follow-ups returning (P < .001), according to the researchers.

Overall, Dr. Bardach’s group estimates that for every 30 children who have follow-up visits with a physician, one would avoid a return trip to the emergency department for asthma within a year.

But given the sheer number of asthma-related trips to the ED each year – 164,145 for kids age 1-17 years in the United States in 2016 alone – that translates into big numbers of kids not going back to the hospital: approximately 72,000 such trips avoided at a savings to the health care system of at least $8.6 million annually.
 

Missed opportunities

Had Ms. Ward’s boys been among the one in five to receive follow-up care earlier in their lives, she might have saved a significant amount of time, money, anxiety, and heartache. When the twins were 9 years old, she took them to a new pediatric pulmonologist. That changed everything. In that first visit, “they gave me way more information than I ever had in the first 9 years,” she said.

The doctor told Ms. Ward to keep steroids on hand, gave her a prescription for extra doses of the powerful medication, and explained that they needed to be used within 24 hours of the first sign of a breathing problem.

“She said if you give them the steroids right away, it keeps them out of the emergency room, and that’s actually worked,” Ms. Ward said. “She made sure we had care plans every visit and asked me each time if I still had it or we needed to rewrite it. They gave me signs to look for, for when to go to hospital visits. I think that when you go to the doctor, they should be telling you stuff like that.”

Dr. Bardach said visits with a primary care doctor or asthma specialist offer families a chance to receive information to keep the condition from becoming critical.

“Going to that follow-up visit, they can get access to education from the provider about how to avoid things that trigger asthma, and there’s medication that kids can take that keeps the lungs calm and less likely to have a big asthma reaction, so getting access to that medication can be really helpful,” she said.

That was the case for Amy Davenport, of Chapel Hill, N.C., whose 6-year-old son has been to the ED twice for his asthma.

The first time, when he was 3, he was having trouble breathing with a respiratory tract infection and received nebulizer treatment – although he received it in the ED since no beds were available in the ICU. The staff did tell Ms. Davenport to follow up with her primary care provider, but her son’s pediatrician was reluctant to diagnose him with asthma at such a young age and didn’t prescribe any maintenance medications.

A few months later, Ms. Davenport and her son found themselves back in the hospital, and an ICU bed was open this time. The critical care staff referred Davenport to a pediatric pulmonary specialist, and they haven’t been back to the hospital since. Ms. Davenport said she believes if they’d received a maintenance medication after the first visit, it likely would have prevented the second one.

“I’ve definitely seen now that, after the second admission, we got an asthma action plan and it said exactly what to do,” she said. “I felt like we had really good follow-up. We had that action plan on our refrigerator for a long time, and it helped us as parents with three small children to manage.”

Of course, follow-up care takes time – time away from work and school that not all families can spare, the researchers acknowledged. Telehealth may be an option, especially after its use expanded during the COVID-19 pandemic.

“We know that health systems have a hard time being flexible enough to actually have a kid be able to make an appointment within a short period of time, and we also know it’s hard for families sometimes to go back into a clinical setting within a certain period of time,” Dr. Bardach said. The urgency for the appointment may wane for those whose children seem to be doing better.

When the researchers adjusted their calculations for socioeconomic status, the results didn’t change much. But the study did find that patients with private insurance were about twice as likely to have follow-up visits as those on Medicaid (43.7% vs. 21.7%). And “the content and conduct” of the follow-up visit makes a difference as well.

Ms. Ward, whose boys are insured through Medicaid, recalled several visits to the ED where she had to push the staff to get the care her children needed. In one case, when one of her boys was a year old and struggling to breathe, the emergency doctor handed her a prescription and recommended she fill it at a neighborhood drugstore that would be cheaper than the hospital’s pharmacy. Then a nurse came in to begin the discharge process.

“I said no, ‘we’re not ready yet. Look at him,’” Ms. Ward said. The nurse took a pulse oximeter reading that showed the boy’s oxygen levels were at 84%, dangerously low. “If I wasn’t so knowledgeable and paid attention when they were born, since they were preemies, if it would have been somebody else, they probably would’ve went home and he’d have died.”

With the pediatric pulmonologist the boys have now, Ms. Ward said she feels more capable of managing their asthma and knowing how to reduce the likelihood that they’ll need to visit the ED.

“Part of what we’re seeing here is that having an existing and trusting relationship with a clinician can be helpful to kids with asthma,” Dr. Bardach said. “If we help establish and maintain those connections, and explain how important that connection can be, that can also help somebody with asthma overall.”

The research was funded by the Agency for Healthcare Research and Quality. The authors disclosed no relevant financial relationships.

Living in coastal areas of Florida and California has great appeal for many, with the warm, sunny climate and nearby fresh water and salt water.

But, unknown to many, those balmy coasts also carry the risk of infection from nontuberculous (atypical) mycobacteria (NTM). Unlike its relative, tuberculosis, NTM is not transmitted from person to person, with one exception: patients with cystic fibrosis.

It is estimated that there were 181,000 people with NTM lung disease in the U.S. in 2015, and according to one study, the incidence is increasing by 8.2% annually among those aged 65 years and older. But NTM doesn’t only affect the elderly; it’s estimated that 31% of all NTM patients are younger than 65 years.

With the warm, moist soil and water, NTM is most commonly found in Florida, California, Hawaii, and the Gulf Coast states. The incidence is somewhat lower in states along the Great Lakes. Other states are not without risk – but NTM is perhaps even more likely to be overlooked in these states by physicians because of a lack of awareness of the disease.

Rebecca Prevots, PhD, MPH, chief of the epidemiology and population studies unit of the Division of Intramural Research at the National Institute of Allergy and Infectious Diseases, told this news organization that “why NTM is increasing is one of the most common questions” she gets, followed by whether it is due to climate change. “The short answer is, we don’t know.”

She suggests that the increase in diagnoses is due to a combination of increased awareness, host susceptibility, and perhaps environmental changes. One problem is that NTM is not a reportable disease. Also, public health resources have been decimated, both through funding cuts and loss of personnel. Dr. Prevots said, “It’s not just NTM surveillance that is important, but you can’t just make a certain condition reportable and expect to have good data without putting resources to it. ... Diseases are made reportable at the state level. There’s no mandated reporting up to CDC. So CDC is piloting reporting events through their emerging infectious program.”

Anthony Cannella, MD, assistant professor of infectious diseases at the University of South Florida (USF), is in the midst of NTM. He told this news organization that “there’s a huge circle with big old dots right over the center of the state.” He is adamant that “a soil-water survey has to occur. We need to know what the devil is happening.”

Florida legislators agreed to allocate $519,000 for NTM testing and surveillance in 2019. But Florida Governor Ron DeSantis vetoed that line item in the budget. WUSF (a National Public Radio affiliate on the USF campus) was unable to get a response to their query about this from the governor’s office.
 

Who gets NTM?

Mycobacterium avium complex primarily causes lung disease, which presents as two clinical syndromes.

“These infections don’t affect everyone,” Kenneth Olivier, MD, MPH, chief of pulmonary clinical medicine, Cardiovascular Pulmonary Branch of the National Heart, Lung, and Blood Institute, said in an interview. They affect “patients that have underlying genetic conditions that cause abnormalities in the airway clearance mechanisms, particularly cystic fibrosis and primary ciliary dyskinesia [and], to some extent, patients with COPD.”

The second group is “comprised mainly of postmenopausal women, many of whom have had no predisposing medical problems prior to onset of generally frequent throat clearing or chronic cough, which is what brings them to medical attention.” Dr. Olivier added that “many of these patients have a fairly unique appearance. They tend to have a high prevalence of curvature of the spine, scoliosis, indentation of the chest wall (pectus excavatum), and physical characteristics that overlap heritable connective tissue disorders like Marfan syndrome or Ehlers-Danlos syndrome.”

Dr. Olivier pointed out a major problem in NTM diagnosis and treatment: “The guidelines-based approach to chronic cough generally calls for treating postnasal drip, airway reactivity, asthma type symptoms first empirically, before doing different diagnostic studies. That generally causes a delay in obtaining things like CT scan, where you can see the characteristic changes.”

Dr. Cannella added, “People are starting to become more aware of it. It’s kind of like pneumocystis back in the 80s. ... We’ve had patients who have had long periods of febrile neutropenia, and NTM wasn’t on the radar. Now we’ve picked up at least seven or eight.”

In addition to pulmonary infections, nosocomial outbreaks have occurred, owing to contaminated heater-cooler units, catheter infections, nail salons, or to medical tourism. These more commonly involve rapidly growing species, such as M abscessus, M chelonae, and M fortuitum. Clinicians should also be aware of skin infections from M marinum, which come from wounds from aquariums, fish, or shellfish. Incubation can occur over months, highlighting the importance of a detailed history and special cultures.
 

Diagnostics

The diagnosis of NTM is delayed for several reasons. One is the lack of awareness among clinicians about NTM and its risk factors, including hobbies such as gardening or working in places where dirt is aerosolized, such as on road crews, or even from hot tubs. A thorough history is critical.

Another is not recognizing the need for an acid-fast bacilli (AFB) culture, which requires specialized media. Fortunately, NTM can be picked up on fungal cultures, Dr. Cannella noted. Clinicians are sometimes discouraged from culturing AFB because doing so may not be cost-effective. And many hospital laboratories are increasingly sending cultures to outside labs, and it can take days – sometimes even more than a week – to receive a report of results.

Charles Daley, MD, chief of the Division of Mycobacterial and Respiratory Infections at National Jewish Health, expressed his frustration about labs in an interview, saying diagnostics is “an important hole in the U.S., as our laboratories do not provide clinicians with the results that they need to make good decisions. Most laboratories in the U.S. just don’t speciate the organisms or subspeciate in the setting of abscesses. They don’t tell the clinician enough about the susceptibility, particularly whether there’s inducible resistance. As a clinician, you just don’t have the information to make the right decisions. ... We need to improve diagnostics in NTM. Everything is there and available. They just don’t want to do it because it increases the costs.”

Men tend to have fibrocavitary disease, which shows on ordinary chest x-rays, but CT scans are essential for women because women tend to have either nodular disease or bronchiectasis, which does not show on a plain film.
 

Treatment

A standard treatment for NTM lung disease includes three or four medications – clarithromycin or azithromycin, rifampin or rifabutin, ethambutol, and streptomycin or amikacin. In vitro resistance is important in predicting the clinical response to a macrolide or amikacin.

For bronchiectatic disease, National Jewish Hospital recommends treatment three times per week rather than daily therapy, as it is better tolerated. Azithromycin is preferred over clarithromycin. Amikacin should be added if there is cavitary or severe disease, and the macrolide is then given daily.

Dr. Olivier suggested that physicians stagger the initiation of those drugs to improve the tolerability of the difficult regimen. Generally, treatment is for 18 months – a year after sputum cultures become negative.

If therapy fails – that is, sputum is persistently positive at 6 months – amikacin liposomal inhalation solution (Arikayce) is likely to be added. Patients should be monitored with monthly safety labs, sputum cultures, and an audiogram (if receiving amikacin). Every 3 months, vestibular tests, eye exams, and spirometry should be conducted, and every 6 months, physicians should order a CT, an audiogram, and an electrocardiogram.

Despite completing such a rigorous regimen, about half of patients experience reinfection because of their underlying host susceptibility. Genomic sequencing shows that these are new infections, not relapses, Dr. Prevots said. She also noted that gastroesophageal reflux disease is a significant risk factor because of chronic aspiration.

Dr. Daley outlined the newer treatments being studied. They include Arikayce, omadocycline, and bedaquiline. He added, “There’s a neutrophil elastase inhibitor trial that’s ongoing, a huge trial. There’s another one looking at basically eosinophilic inflammation.”

Other trials are in the offing, he said, all focusing on the inflammatory response – a development he described as exciting, because for the longest time, there were few if any NTM trials.

Dr. Cannella is also buoyed by the potential synergy of dual beta-lactam therapy with ceftaroline and a carbapenem for M abscessus infections, which are notoriously difficult to treat.

There are unique problems facing drug development for NTM because, for approval, the U.S. Food and Drug Administration requires the drug to “improve how a patient feels, functions, or survives.” NTM is associated with low mortality, so that “is off the table,” Dr. Daley explained. It’s hard to quantify improvement in function. The top two symptoms to measure are coughing and fatigue, he said. But both are difficult to measure, and some of the medicines worsen cough. Some research groups are now trying to validate patient-reported outcome instruments to satisfy the FDA’s requirements.
 

Tips for patients and physicians

The experts this news organization spoke to had very consistent recommendations for patients:

• NTM is resistant to chlorine and bromine, so tap water is a major source of infection. Patients should consider to greater than 130° F and using metal showerheads or bathing rather than showering.
• Good bathroom ventilation helps.
• Patients should consider using a water filter that filters entities less than 5 mcm in size – but not carbon filters, which concentrate the organisms.
• Humidifiers and hot tubs should be avoided.
• A good face mask, such as an N95, should be worn when gardening or repotting plants.

Dr. Olivier stressed that clinicians should familiarize themselves with the guidelines for diagnosing and treating NTM. In particular, clinicians should be aware that using azithromycin for bronchitis might cause resistance in NTM. “Macrolide resistance turns what may be a slowly progressive or bothersome infection into a lethal infection with a 1-year mortality of 35%.”

He concluded, “I would just urge that if the patient’s on their second or third Z-Pak within a year, it’s probably time to look for other causes of what might be happening.”

Dr. Cannella, Dr. Prevots, and Dr. Olivier reported no relevant financial relationships. Dr. Cannella adds, “My views are not those of my employers, the U.S. Dept of VA, or the University of South Florida Morsani College of Medicine.” Dr. Daley reports research grants/contracts with AN2, Beyond Air, Bugworks, Insmed, and Paratek and service on advisory boards or as a consultant for AN2, AstraZeneca, Genentech, Insmed, Matinas, Paratek, Pfizer, and Spero.

Living in coastal areas of Florida and California has great appeal for many, with the warm, sunny climate and nearby fresh water and salt water.

But, unknown to many, those balmy coasts also carry the risk of infection from nontuberculous (atypical) mycobacteria (NTM). Unlike its relative, tuberculosis, NTM is not transmitted from person to person, with one exception: patients with cystic fibrosis.

It is estimated that there were 181,000 people with NTM lung disease in the U.S. in 2015, and according to one study, the incidence is increasing by 8.2% annually among those aged 65 years and older. But NTM doesn’t only affect the elderly; it’s estimated that 31% of all NTM patients are younger than 65 years.

With the warm, moist soil and water, NTM is most commonly found in Florida, California, Hawaii, and the Gulf Coast states. The incidence is somewhat lower in states along the Great Lakes. Other states are not without risk – but NTM is perhaps even more likely to be overlooked in these states by physicians because of a lack of awareness of the disease.

Rebecca Prevots, PhD, MPH, chief of the epidemiology and population studies unit of the Division of Intramural Research at the National Institute of Allergy and Infectious Diseases, told this news organization that “why NTM is increasing is one of the most common questions” she gets, followed by whether it is due to climate change. “The short answer is, we don’t know.”

She suggests that the increase in diagnoses is due to a combination of increased awareness, host susceptibility, and perhaps environmental changes. One problem is that NTM is not a reportable disease. Also, public health resources have been decimated, both through funding cuts and loss of personnel. Dr. Prevots said, “It’s not just NTM surveillance that is important, but you can’t just make a certain condition reportable and expect to have good data without putting resources to it. ... Diseases are made reportable at the state level. There’s no mandated reporting up to CDC. So CDC is piloting reporting events through their emerging infectious program.”

Anthony Cannella, MD, assistant professor of infectious diseases at the University of South Florida (USF), is in the midst of NTM. He told this news organization that “there’s a huge circle with big old dots right over the center of the state.” He is adamant that “a soil-water survey has to occur. We need to know what the devil is happening.”

Florida legislators agreed to allocate $519,000 for NTM testing and surveillance in 2019. But Florida Governor Ron DeSantis vetoed that line item in the budget. WUSF (a National Public Radio affiliate on the USF campus) was unable to get a response to their query about this from the governor’s office.
 

Who gets NTM?

Mycobacterium avium complex primarily causes lung disease, which presents as two clinical syndromes.

“These infections don’t affect everyone,” Kenneth Olivier, MD, MPH, chief of pulmonary clinical medicine, Cardiovascular Pulmonary Branch of the National Heart, Lung, and Blood Institute, said in an interview. They affect “patients that have underlying genetic conditions that cause abnormalities in the airway clearance mechanisms, particularly cystic fibrosis and primary ciliary dyskinesia [and], to some extent, patients with COPD.”

The second group is “comprised mainly of postmenopausal women, many of whom have had no predisposing medical problems prior to onset of generally frequent throat clearing or chronic cough, which is what brings them to medical attention.” Dr. Olivier added that “many of these patients have a fairly unique appearance. They tend to have a high prevalence of curvature of the spine, scoliosis, indentation of the chest wall (pectus excavatum), and physical characteristics that overlap heritable connective tissue disorders like Marfan syndrome or Ehlers-Danlos syndrome.”

Dr. Olivier pointed out a major problem in NTM diagnosis and treatment: “The guidelines-based approach to chronic cough generally calls for treating postnasal drip, airway reactivity, asthma type symptoms first empirically, before doing different diagnostic studies. That generally causes a delay in obtaining things like CT scan, where you can see the characteristic changes.”

Dr. Cannella added, “People are starting to become more aware of it. It’s kind of like pneumocystis back in the 80s. ... We’ve had patients who have had long periods of febrile neutropenia, and NTM wasn’t on the radar. Now we’ve picked up at least seven or eight.”

In addition to pulmonary infections, nosocomial outbreaks have occurred, owing to contaminated heater-cooler units, catheter infections, nail salons, or to medical tourism. These more commonly involve rapidly growing species, such as M abscessus, M chelonae, and M fortuitum. Clinicians should also be aware of skin infections from M marinum, which come from wounds from aquariums, fish, or shellfish. Incubation can occur over months, highlighting the importance of a detailed history and special cultures.
 

Diagnostics

The diagnosis of NTM is delayed for several reasons. One is the lack of awareness among clinicians about NTM and its risk factors, including hobbies such as gardening or working in places where dirt is aerosolized, such as on road crews, or even from hot tubs. A thorough history is critical.

Another is not recognizing the need for an acid-fast bacilli (AFB) culture, which requires specialized media. Fortunately, NTM can be picked up on fungal cultures, Dr. Cannella noted. Clinicians are sometimes discouraged from culturing AFB because doing so may not be cost-effective. And many hospital laboratories are increasingly sending cultures to outside labs, and it can take days – sometimes even more than a week – to receive a report of results.

Charles Daley, MD, chief of the Division of Mycobacterial and Respiratory Infections at National Jewish Health, expressed his frustration about labs in an interview, saying diagnostics is “an important hole in the U.S., as our laboratories do not provide clinicians with the results that they need to make good decisions. Most laboratories in the U.S. just don’t speciate the organisms or subspeciate in the setting of abscesses. They don’t tell the clinician enough about the susceptibility, particularly whether there’s inducible resistance. As a clinician, you just don’t have the information to make the right decisions. ... We need to improve diagnostics in NTM. Everything is there and available. They just don’t want to do it because it increases the costs.”

Men tend to have fibrocavitary disease, which shows on ordinary chest x-rays, but CT scans are essential for women because women tend to have either nodular disease or bronchiectasis, which does not show on a plain film.
 

Treatment

A standard treatment for NTM lung disease includes three or four medications – clarithromycin or azithromycin, rifampin or rifabutin, ethambutol, and streptomycin or amikacin. In vitro resistance is important in predicting the clinical response to a macrolide or amikacin.

For bronchiectatic disease, National Jewish Hospital recommends treatment three times per week rather than daily therapy, as it is better tolerated. Azithromycin is preferred over clarithromycin. Amikacin should be added if there is cavitary or severe disease, and the macrolide is then given daily.

Dr. Olivier suggested that physicians stagger the initiation of those drugs to improve the tolerability of the difficult regimen. Generally, treatment is for 18 months – a year after sputum cultures become negative.

If therapy fails – that is, sputum is persistently positive at 6 months – amikacin liposomal inhalation solution (Arikayce) is likely to be added. Patients should be monitored with monthly safety labs, sputum cultures, and an audiogram (if receiving amikacin). Every 3 months, vestibular tests, eye exams, and spirometry should be conducted, and every 6 months, physicians should order a CT, an audiogram, and an electrocardiogram.

Despite completing such a rigorous regimen, about half of patients experience reinfection because of their underlying host susceptibility. Genomic sequencing shows that these are new infections, not relapses, Dr. Prevots said. She also noted that gastroesophageal reflux disease is a significant risk factor because of chronic aspiration.

Dr. Daley outlined the newer treatments being studied. They include Arikayce, omadocycline, and bedaquiline. He added, “There’s a neutrophil elastase inhibitor trial that’s ongoing, a huge trial. There’s another one looking at basically eosinophilic inflammation.”

Other trials are in the offing, he said, all focusing on the inflammatory response – a development he described as exciting, because for the longest time, there were few if any NTM trials.

Dr. Cannella is also buoyed by the potential synergy of dual beta-lactam therapy with ceftaroline and a carbapenem for M abscessus infections, which are notoriously difficult to treat.

There are unique problems facing drug development for NTM because, for approval, the U.S. Food and Drug Administration requires the drug to “improve how a patient feels, functions, or survives.” NTM is associated with low mortality, so that “is off the table,” Dr. Daley explained. It’s hard to quantify improvement in function. The top two symptoms to measure are coughing and fatigue, he said. But both are difficult to measure, and some of the medicines worsen cough. Some research groups are now trying to validate patient-reported outcome instruments to satisfy the FDA’s requirements.

Patients with COVID-19, especially those with an altered sense of smell, have significantly more axon and microvasculopathy damage in the brain’s olfactory tissue versus non-COVID patients. These new findings from a postmortem study may explain long-term loss of smell in some patients with the virus.

“The striking axonal pathology in some cases indicates that olfactory dysfunction in COVID-19 may be severe and permanent,” the investigators led by Cheng-Ying Ho, MD, PhD, associate professor, department of pathology, Johns Hopkins University School of Medicine, Baltimore, write.

“The results show the damage caused by COVID can extend beyond the nasal cavity and involve the brain,” Dr. Ho told this news organization.

The study was published online April 11 in JAMA Neurology.
 

A more thorough investigation

Patients infected with SARS-CoV-2, which causes COVID-19, present with a wide range of symptoms. In addition to respiratory illnesses, they may exhibit various nonrespiratory manifestations of COVID-19.

One of the most prevalent of these is olfactory dysfunction. Research shows such dysfunction, including anosmia (loss of smell), hyposmia (reduced sense of smell), and parosmia (smells that are distorted or unpleasant), affects 30%-60% of patients with COVID-19, said Dr. Ho.

However, these statistics come from research before the advent of the Omicron variant, which evidence suggests causes less smell loss in patients with COVID, she said.

Previous studies in this area mainly focused on the lining of the nasal cavity. “We wanted to go a step beyond to see how the olfactory bulb was affected by COVID infection,” said Dr. Ho.

The study included 23 deceased patients with confirmed COVID-19 ranging in age from 28 to 93 years at death (median 62 years, 60.9% men). It also included 14 controls who tested negative for COVID-19, ranging in age from 20 to 77 years (median 53.5 years, 50% men).

Researchers collected postmortem tissue from the brain, lung, and other organs and reviewed pertinent clinical information.

Most patients with COVID died of COVID pneumonia or related complications, although some died from a different cause. Some had an active COVID infection and others were “post infection, meaning they were in the recovery stage,” said Dr. Ho.

Six patients with COVID-19 and eight controls had significant brain pathology.

Compared with controls, those with COVID-19 showed significantly worse olfactory axonal damage. The mean axon pathology score (range 1-3 with 3 the worst) was 1.921 in patients with COVID-19 and 1.198 in controls (95% confidence interval, 0.444-1.002; P < .001).

The mean axon density in the lateral olfactory tract was significantly less in patients with COVID-19 than in controls (P = .002), indicating a 23% loss of olfactory axons in the COVID group.

Comparing COVID patients with and without reported loss of smell, researchers found those with an altered sense of smell had significantly more severe olfactory axon pathology.
 

Vascular damage

Patients with COVID also had worse vascular damage. The mean microvasculopathy score (range, 1-3) was 1.907 in patients with COVID-19 and 1.405 in controls (95% CI, 0.259-0.745; P < .001).

There was no evidence of the virus in the olfactory tissue of most patients, suggesting the olfactory pathology was likely caused by vascular damage, said Dr. Ho.

What’s unique about SARS-CoV-2 is that, although it’s a respiratory virus, it’s capable of infecting endothelial cells lining vessels.

“Other respiratory viruses only attack the airways and won’t attack vessels, but vascular damage has been seen in the heart and lung in COVID patients, and our study showed the same findings in the olfactory bulb,” Dr. Ho explained.

The researchers divided patients with COVID by infection severity: mild, moderate, severe, and critical. Interestingly, those with the most severe olfactory pathology were the ones with milder infections, said Dr. Ho.

She noted other studies have reported patients with mild infection are more likely to lose the sense of smell than those with severe infection, but she’s skeptical about this finding.

“Patients with severe COVID are usually hospitalized and intubated, so it’s hard to get them to tell you whether they’ve lost smell or not; they have other more important issues to deal with like respiratory failure,” said Dr. Ho.

Advanced age is associated with neuropathologic changes, such as tau deposits, so the researchers conducted an analysis factoring in age-related brain changes. They found a COVID-19 diagnosis remained associated with increased axonal pathology, reduced axonal density, and increased vascular pathology.

“This means that the COVID patients had more severe olfactory pathology not just because they had more tau pathology,” Dr. Ho added.
 

New guidance for patients

Commenting for this news organization, Davangere P. Devanand, MD, professor of psychiatry and neurology and director of geriatric psychiatry, Columbia University Irving Medical Center, New York, said the findings indicate the damage from COVID in the olfactory pathway may not be reversible as was previously thought.

“This has been suggested before as a possibility, but the autopsy findings in this case series indicate clearly that there may be permanent damage,” he said.

The results highlight the need to monitor patients with COVID for a smell deficit, said Dr. Devanand. 

“Assuring patients of a full recovery in smell and taste may not be sound advice, although recovery does occur in many patients,” he added.

He praised the study design, especially the blinding of raters, but noted a number of weaknesses, including the small sample size and the age and gender discrepancies between the groups.

Another possible limitation was inclusion of patients with Alzheimer’s and Lewy body pathology, said Dr. Devanand.

“These patients typically already have pathology in the olfactory pathways, which means we don’t know if it was COVID or the underlying brain pathology contributing to smell difficulties in these patients,” he said.

He noted that, unlike deceased COVID cases in the study, patients who survive COVID may not experience axonal and microvascular injury in olfactory neurons and pathways and their sense of smell may make a full return.

Dr. Devanand said he would have liked more detailed information on the clinical history and course of study participants and whether these factors affected the pathology findings.

The study was supported by grants from the National Institutes of Health.

Dr. Ho and Dr. Devanand have reported no relevant financial disclosures.

“This has been suggested before as a possibility, but the autopsy findings in this case series indicate clearly that there may be permanent damage,” he said.

The results highlight the need to monitor patients with COVID for a smell deficit, said Dr. Devanand. 

“Assuring patients of a full recovery in smell and taste may not be sound advice, although recovery does occur in many patients,” he added.

He praised the study design, especially the blinding of raters, but noted a number of weaknesses, including the small sample size and the age and gender discrepancies between the groups.

Another possible limitation was inclusion of patients with Alzheimer’s and Lewy body pathology, said Dr. Devanand.

“These patients typically already have pathology in the olfactory pathways, which means we don’t know if it was COVID or the underlying brain pathology contributing to smell difficulties in these patients,” he said.

He noted that, unlike deceased COVID cases in the study, patients who survive COVID may not experience axonal and microvascular injury in olfactory neurons and pathways and their sense of smell may make a full return.

Dr. Devanand said he would have liked more detailed information on the clinical history and course of study participants and whether these factors affected the pathology findings.

Patients with COVID-19, especially those with an altered sense of smell, have significantly more axon and microvasculopathy damage in the brain’s olfactory tissue versus non-COVID patients. These new findings from a postmortem study may explain long-term loss of smell in some patients with the virus.

“The striking axonal pathology in some cases indicates that olfactory dysfunction in COVID-19 may be severe and permanent,” the investigators led by Cheng-Ying Ho, MD, PhD, associate professor, department of pathology, Johns Hopkins University School of Medicine, Baltimore, write.

“The results show the damage caused by COVID can extend beyond the nasal cavity and involve the brain,” Dr. Ho told this news organization.

The study was published online April 11 in JAMA Neurology.
 

A more thorough investigation

Patients infected with SARS-CoV-2, which causes COVID-19, present with a wide range of symptoms. In addition to respiratory illnesses, they may exhibit various nonrespiratory manifestations of COVID-19.

One of the most prevalent of these is olfactory dysfunction. Research shows such dysfunction, including anosmia (loss of smell), hyposmia (reduced sense of smell), and parosmia (smells that are distorted or unpleasant), affects 30%-60% of patients with COVID-19, said Dr. Ho.

However, these statistics come from research before the advent of the Omicron variant, which evidence suggests causes less smell loss in patients with COVID, she said.

Previous studies in this area mainly focused on the lining of the nasal cavity. “We wanted to go a step beyond to see how the olfactory bulb was affected by COVID infection,” said Dr. Ho.

The study included 23 deceased patients with confirmed COVID-19 ranging in age from 28 to 93 years at death (median 62 years, 60.9% men). It also included 14 controls who tested negative for COVID-19, ranging in age from 20 to 77 years (median 53.5 years, 50% men).

Researchers collected postmortem tissue from the brain, lung, and other organs and reviewed pertinent clinical information.

Most patients with COVID died of COVID pneumonia or related complications, although some died from a different cause. Some had an active COVID infection and others were “post infection, meaning they were in the recovery stage,” said Dr. Ho.

Six patients with COVID-19 and eight controls had significant brain pathology.

Compared with controls, those with COVID-19 showed significantly worse olfactory axonal damage. The mean axon pathology score (range 1-3 with 3 the worst) was 1.921 in patients with COVID-19 and 1.198 in controls (95% confidence interval, 0.444-1.002; P < .001).

The mean axon density in the lateral olfactory tract was significantly less in patients with COVID-19 than in controls (P = .002), indicating a 23% loss of olfactory axons in the COVID group.

Comparing COVID patients with and without reported loss of smell, researchers found those with an altered sense of smell had significantly more severe olfactory axon pathology.
 

Vascular damage

Patients with COVID also had worse vascular damage. The mean microvasculopathy score (range, 1-3) was 1.907 in patients with COVID-19 and 1.405 in controls (95% CI, 0.259-0.745; P < .001).

There was no evidence of the virus in the olfactory tissue of most patients, suggesting the olfactory pathology was likely caused by vascular damage, said Dr. Ho.

What’s unique about SARS-CoV-2 is that, although it’s a respiratory virus, it’s capable of infecting endothelial cells lining vessels.

“Other respiratory viruses only attack the airways and won’t attack vessels, but vascular damage has been seen in the heart and lung in COVID patients, and our study showed the same findings in the olfactory bulb,” Dr. Ho explained.

The researchers divided patients with COVID by infection severity: mild, moderate, severe, and critical. Interestingly, those with the most severe olfactory pathology were the ones with milder infections, said Dr. Ho.

She noted other studies have reported patients with mild infection are more likely to lose the sense of smell than those with severe infection, but she’s skeptical about this finding.

“Patients with severe COVID are usually hospitalized and intubated, so it’s hard to get them to tell you whether they’ve lost smell or not; they have other more important issues to deal with like respiratory failure,” said Dr. Ho.

Advanced age is associated with neuropathologic changes, such as tau deposits, so the researchers conducted an analysis factoring in age-related brain changes. They found a COVID-19 diagnosis remained associated with increased axonal pathology, reduced axonal density, and increased vascular pathology.

“This means that the COVID patients had more severe olfactory pathology not just because they had more tau pathology,” Dr. Ho added.

U.K. scientists said microplastics may pose even more of a threat than previously thought after confirming their presence in lung tissue taken from living people.

Microplastics were identified in all lung regions, but significantly higher levels were found in the lower lung.

The results supported inhalation as an exposure risk, according to the team from the University of Hull and Hull York Medical School (England), who said their findings could support further investigations into the effects of airborne microplastics on respiratory health.

The study, published in Science of the Total Environment, used lung tissue collected from surgical procedures on patients during routine medical care at Castle Hill Hospital in East Yorkshire.
 

Polypropylene and polyethylene

It found 39 microplastics in 11 of the 13 lung tissue samples tested using micro-Fourier-transform infrared (μFTIR) analysis, which the scientists said was considerably higher than results from previous laboratory tests.

Of microplastics detected, 12 polymer types were identified, of which the most common were polypropylene, (23%) polyethylene terephthalate (18%), and resin (15%). The fibers are commonly found in packaging, bottles, clothing, rope and twine manufacture, and other industries, the scientists said.

Microplastics with dimensions as small as 4 μm were found, but the scientists said they were surprised to discover samples as large as greater than 2 mm within all lung region samples, with the majority being fibrous and fragmented.

The study identified 11 microplastics in the upper part of the lung, seven in the mid part, and 21 in the lower part of the lung.

Laura Sadofsky, the study’s lead author, said: “Microplastics have previously been found in human cadaver autopsy samples. This is the first robust study to show microplastics in lungs from live people. It also shows that they are in the lower parts of the lung. Lung airways are very narrow, so no one thought they could possibly get there, but they clearly have.”

There were also considerably higher levels of microplastics found in male patients, compared with female patients.
 

Future investigations into health implications

“The characterization of types and levels of microplastics we have found can now inform realistic conditions for laboratory exposure experiments with the aim of determining health impacts,” said Laura Sadofsky, who is a senior lecturer in respiratory medicine in the Centre for Atherothrombotic and Metabolic Research at Hull York Medical School.

The latest investigation followed previous research by the medical school and the University of Hull, which found high levels of atmospheric microplastics within the Humber region.

That study, published in Atmosphere, identified resins, which could have originated from degraded roads, paint marking, or tire rubber, as well as polyethylene fibers.

When Sigmund Freud claimed that “anatomy is destiny” he was referring to anatomical sex as a determinant of personality traits. Expert consensus statements have previously offered some recommendations for managing these syndromes, but clinical data are scarce, so the present review “is intended to establish a starting point for future research,”

That notion has been widely discredited, but Freud appears to be inadvertently right in one respect: When it comes to chronic obstructive pulmonary disease (COPD), anatomy really is destiny, and sex may be as well, pulmonary researchers say.

There is a growing body of evidence to indicate that COPD affects men and women differently, and that men and women patients with COPD require different clinical management. Yet women are often underdiagnosed or misdiagnosed, partly because of poorly understood sex differences, but also because of cultural biases.

But plunging any farther into the weeds, it’s important to define terms. Although various investigators have used the terms “sex” and “gender” interchangeably, sex is the preferred term when referring to biological attributes of individual patients, while gender refers to personal identity.

These distinctions are important, contended Amik Sodhi, MBBS, MPH, from the division of allergy, pulmonology, and critical care medicine at the University of Wisconsin–Madison.

“Sex is essentially a biologic construct, so it’s got to do with the sex chromosomes, the genetics of that person, and it refers to the anatomic variations that can change susceptibility to different diseases,” she said in an interview.

An example of sex differences or “sexual dimorphism” can be found in a recent meta-analysis of sex-based genetic associations by Megan Hardin, MD, MPH from Brigham & Women’s Hospital in Boston and colleagues.

They reported that CELSR1, a gene involved in fetal lung development, was expressed more among women than among men and that a single nucleotide polymorphism in the gene was associated with COPD among women smokers, but not among men smokers.

The finding points to a potential risk locus for COPD in women, and could help shed light on sexual dimorphism in COPD, Dr. Hardin and colleagues said.

In contrast to sex, “gender is more of a psychosocial construct which can impact how diseases manifest themselves, how they are potentially managed, and what outcomes might occur for that particular disease,” Dr. Sodhi said.

She and her colleagues recently published a review of sex and gender in common lung disorders and sleep in the journal CHEST, where they wrote that the “influence of sex and gender is portrayed in epidemiological data, disease pathogenesis and pathophysiology, clinical manifestations, response to treatment, access to care, and health outcomes. Hence, sex and gender should be considered in all types of research, clinical practice and educational curricula.”

For example, as previously reported at the 2021 annual meeting of the American Thoracic Society, sex-specific differences in the severity of symptoms and prevalence of comorbidities in patients with COPD may point to different criteria for diagnosing cardiac comorbidities in women and men.

Those conclusions came from a retrospective analysis of data on 795 women and 1,251 men with GOLD (Global Initiative for Chronic Obstructive Lung Disease) class 1-3 disease.

The investigators looked at the patients’ clinical history, comorbidities, lung function, COPD Assessment Test scores, and modified Medical Research Council (mMRC) dyspnea score, and found significant differences between men and women for most functional parameters and comorbidities, and for CAT items of cough, phlegm, and energy.

In logistic regression analysis, predictors for cardiac disease in men were energy, mMRC score, smoking status, body mass index, age, and spirometric lung function, but in women only age was significantly predictive for cardiac disease.

An example of gender effects on COPD differences in men and women is the increase in cigarette advertising aimed at women in the 1960s and the advent of women-targeted brands such as Virginia Slims, which in turn lead to increased smoking rates among women. In addition, in the developing world, where the sex/gender gap in COPD is narrowing, women tend to have greater exposure to wood smoke and cooking fuels in unventilated or poorly ventilated spaces, compared with men.
 

Increasing incidence among women

According to the Centers for Disease Control and Prevention, chronic lower respiratory diseases, primarily COPD, were the fourth-leading cause of death in women in the United States in 2018, following only heart disease, cancer, and accidents/injuries.

And as a CDC analysis of data from the 2013 Behavioral Risk Factor Surveillance System showed, women were more likely to report being told by a physician that they had COPD than did men (6.6%, compared with 5.4%).

Dr. Sodhi and colleagues noted that, at all time points examined from 2005 to 2014, women had a higher proportion than men of COPD hospitalizations and in-hospital deaths. They also noted that female sex is associated with a threefold risk for severe early-onset COPD, and that women with COPD have lower diffusion capacity of lungs for carbon monoxide, despite having higher predicted forced expiratory volume in 1 second, compared with men.

“Historically, COPD wasn’t a disease that was so prevalent in women. It’s been in the past 20 years that the trends have changed,” said Patricia Silveyra, MSc, PhD, ATSF, associate professor of environmental and occupational health at Indiana University, Bloomington.

The increasing prevalence of COPD among women cannot be explained by smoking alone, she said in an interview.

“It used to be thought that it was because more women smoked, but actually a lot of women who don’t smoke can develop COPD, so it appears to be probably something environmental, but because it used to be a disease of older men, in the clinic there was also a bias to diagnose men with COPD, and women with asthma, so a lot of women went underdiagnosed,” Dr. Silveyra said.

In their review, Dr. Sodhi and colleagues noted that women with COPD “may be underdiagnosed as a result of having different symptoms from those classically recognized. Reasons for underdiagnosis or a delay in diagnosis may also be due to lack of a formal evaluation with spirometry, women seeking care later in the course of disease, physician bias, or associated fatigue or depression misdirecting diagnostic strategies. Underdiagnosis may be associated with psychological distress and worse health-related quality of life.”

Although the evidence is mixed, women tend to present more frequently with the chronic bronchitis phenotype of COPD, compared with the emphysema phenotype, and women tend to have greater degrees of pulmonary function impairment when exposed to tobacco smoke, even after controlling for differences in height and weight.

“For the same amount of exposure to tobacco smoke, females are likely to develop more severe airflow limitation at an earlier age than males, and have more exacerbation,” Dr. Sodhi and colleagues wrote.

Both Dr. Silveyra and Dr. Sodhi said that reason why men and women differ in their physiological reactions to smoke are still unknown.
 

Sex differences in drug responses

There is only limited evidence to indicate that women and men respond differently to various therapeutic agents, but what is clear is that more research into this area is needed, Dr. Sodhi and Dr. Silveyra said.

For example, among the few studies that have documented sex differences, one showed no sex differences in the efficacy of salmeterol/fluticasone combination therapy for reducing exacerbations or improving quality of life, whereas another showed that women were more likely than men to experience COPD symptoms or exacerbations after stopping inhaled corticosteroids, Dr. Sodhi and colleagues noted.

Both Dr. Sodhi and Dr. Silveyra emphasized the need for clinical trials that study the effects of sex on treatment outcomes in COPD, which could lead to better, more personalized therapeutic regimens that take sex and gender into account.

Dr. Sodhi and colleagues offered the following advice to clinicians: “Interaction with female patients should take into account that their symptoms may not conform to traditionally accepted presentations. Challenges exist for female patients at all levels of health care interaction and as clinicians we need to acknowledge the bias and willfully work toward recognition and elimination of unconscious and conscious bias. Empowering our patients to have frank discussions with their health care team when they perceive bias is another step to help promote equity.”

The review by Dr. Sodhi and colleagues was supported by grants from the National Institutes of Health. Dr. Sodhi and Dr. Silveyra reported having no conflicts of interest to disclose.

An example of gender effects on COPD differences in men and women is the increase in cigarette advertising aimed at women in the 1960s and the advent of women-targeted brands such as Virginia Slims, which in turn lead to increased smoking rates among women. In addition, in the developing world, where the sex/gender gap in COPD is narrowing, women tend to have greater exposure to wood smoke and cooking fuels in unventilated or poorly ventilated spaces, compared with men.
 

Increasing incidence among women

According to the Centers for Disease Control and Prevention, chronic lower respiratory diseases, primarily COPD, were the fourth-leading cause of death in women in the United States in 2018, following only heart disease, cancer, and accidents/injuries.

And as a CDC analysis of data from the 2013 Behavioral Risk Factor Surveillance System showed, women were more likely to report being told by a physician that they had COPD than did men (6.6%, compared with 5.4%).

Dr. Sodhi and colleagues noted that, at all time points examined from 2005 to 2014, women had a higher proportion than men of COPD hospitalizations and in-hospital deaths. They also noted that female sex is associated with a threefold risk for severe early-onset COPD, and that women with COPD have lower diffusion capacity of lungs for carbon monoxide, despite having higher predicted forced expiratory volume in 1 second, compared with men.

“Historically, COPD wasn’t a disease that was so prevalent in women. It’s been in the past 20 years that the trends have changed,” said Patricia Silveyra, MSc, PhD, ATSF, associate professor of environmental and occupational health at Indiana University, Bloomington.

The increasing prevalence of COPD among women cannot be explained by smoking alone, she said in an interview.

“It used to be thought that it was because more women smoked, but actually a lot of women who don’t smoke can develop COPD, so it appears to be probably something environmental, but because it used to be a disease of older men, in the clinic there was also a bias to diagnose men with COPD, and women with asthma, so a lot of women went underdiagnosed,” Dr. Silveyra said.

In their review, Dr. Sodhi and colleagues noted that women with COPD “may be underdiagnosed as a result of having different symptoms from those classically recognized. Reasons for underdiagnosis or a delay in diagnosis may also be due to lack of a formal evaluation with spirometry, women seeking care later in the course of disease, physician bias, or associated fatigue or depression misdirecting diagnostic strategies. Underdiagnosis may be associated with psychological distress and worse health-related quality of life.”

Although the evidence is mixed, women tend to present more frequently with the chronic bronchitis phenotype of COPD, compared with the emphysema phenotype, and women tend to have greater degrees of pulmonary function impairment when exposed to tobacco smoke, even after controlling for differences in height and weight.

“For the same amount of exposure to tobacco smoke, females are likely to develop more severe airflow limitation at an earlier age than males, and have more exacerbation,” Dr. Sodhi and colleagues wrote.

Both Dr. Silveyra and Dr. Sodhi said that reason why men and women differ in their physiological reactions to smoke are still unknown.
 

Sex differences in drug responses

There is only limited evidence to indicate that women and men respond differently to various therapeutic agents, but what is clear is that more research into this area is needed, Dr. Sodhi and Dr. Silveyra said.

For example, among the few studies that have documented sex differences, one showed no sex differences in the efficacy of salmeterol/fluticasone combination therapy for reducing exacerbations or improving quality of life, whereas another showed that women were more likely than men to experience COPD symptoms or exacerbations after stopping inhaled corticosteroids, Dr. Sodhi and colleagues noted.

Both Dr. Sodhi and Dr. Silveyra emphasized the need for clinical trials that study the effects of sex on treatment outcomes in COPD, which could lead to better, more personalized therapeutic regimens that take sex and gender into account.

Dr. Sodhi and colleagues offered the following advice to clinicians: “Interaction with female patients should take into account that their symptoms may not conform to traditionally accepted presentations. Challenges exist for female patients at all levels of health care interaction and as clinicians we need to acknowledge the bias and willfully work toward recognition and elimination of unconscious and conscious bias. Empowering our patients to have frank discussions with their health care team when they perceive bias is another step to help promote equity.”

The review by Dr. Sodhi and colleagues was supported by grants from the National Institutes of Health. Dr. Sodhi and Dr. Silveyra reported having no conflicts of interest to disclose.

Since the start of the pandemic, supply-chain problems have permeated just about every industry sector. While most of the media attention has focused on toilet paper and retail shipment delays, a darker, more sinister supply chain disruption has been unfolding, one that entails a sophisticated criminal enterprise that has been operating at scale to distribute and profit from counterfeit HIV drugs.

Recently, news has emerged – most notably in the Wall Street Journal – with reports of a Justice Department investigation into what appears to be a national drug trafficking network comprising more than 70 distributors and marketers.

The details read like a best-selling crime novel.

Since last year, authorities have seized 85,247 bottles of counterfeit HIV drugs, both Biktarvy (bictegravir 50 mg, emtricitabine 200 mg, and tenofovir alafenamide 25 mg tablets) and Descovy (emtricitabine 200 mg and tenofovir alafenamide 25 mg tablets). Law enforcement has conducted raids at 17 locations in eight states. Doctored supply chain papers have provided cover for the fake medicines and the individuals behind them.

But unlike the inconvenience of sparse toilet paper, this crime poses life-threatening risks to millions of patients with HIV who rely on Biktarvy to suppress the virus or Descovy to prevent infection from it. Even worse, some patients have been exposed to over-the-counter painkillers or the antipsychotic drug quetiapine fumarate masquerading as HIV drugs in legitimate but repurposed bottles.

Gilead Sciences (Foster City, Calif.), which manufactures both Biktarvy and Descovy, declined to comment when contacted, instead referring this news organization to previous press statements.
 

Falsified HIV medications, illicit purchases over 2 Years

On Aug. 5, 2021, Gilead first warned the public that it had become aware of tampered and counterfeit Biktarvy and Descovy tablets. In coordination with the Food and Drug Administration, it alerted pharmacies to “investigate the potential for counterfeit or tampered Gilead medication sold by [unauthorized] distributors that may be within their recent supply.”

On Jan. 19, 2022, Gilead issued a second statement outlining ongoing actions in coordination with U.S. marshals and local law enforcement to remove these illegal medications from circulation and prevent further distribution.

The timing of the most recent announcement was not accidental. The day before, a federal judge serving the U.S. District Court for the Eastern District of New York unsealed documents detailing the company’s lawsuit against dozens of individuals and entities who they alleged had engaged in a highly coordinated effort to defraud pharmacies and consumers. The suit followed two prior Gilead filings that ultimately resulted in court-issued ex parte seizure orders (orders that allow a court to seize property without the property owner’s consent) and the recovery of more than 1,000 bottles containing questionable Gilead medications.

The lawsuit centered on Cambridge, Mass.–based wholesale pharmaceutical distributor Safe Chain Solutions and its two cofounders. The document is peppered with terms such as “shifting series of fly-by-night corporate entities,” “gray market” distributors, a “dedicated sales force,” and “shell entities,” along with accusations that the defendants were believed to have made purchases of gold bullion, jewelry, and other luxury items for conversion into cash.

In a curious twist of fate, this sinister effort appeared to have been first revealed not by a pharmacist but by a patient who had returned a bottle of Biktarvy with “foreign medication inside” to the California pharmacy that dispensed it.

“Specifically with HIV medications, there’s no point in which the pharmacy is actually opening the bottle, breaking the seal, and counting out pills to put into a smaller prescription bottle,” Emily Heil, PharmD, BCIDP, AAHIVP, associate professor of infectious diseases in the department of pharmacy practice and science at the University of Maryland School of Pharmacy, Baltimore, told this news organization.

“But that’s also why pharmacies work with these centralized groups of distributors that maintain a chain of command and fidelity with drug manufacturers so that we don’t run into these situations,” she said.

This is the link in the chain where that tightly coordinated and highly regulated process was broken.

Although Gilead and Safe Chain Solutions were informed of the incident as early as August 2020, the distributor repeatedly refused to identify the supplier and the pedigree (the record demonstrating the chain of all sales or transfers of a specific drug, going back to the manufacturer, as required by the FDA’s Drug Supply Chain Security Act in 2013).

Later that year, Janssen Pharmaceutical Companies of Johnson & Johnson issued a media statement saying that they had been alerted to the distribution of counterfeit Symtuza (darunavir/cobicistat/emtricitabine/tenofovir alafenamide) to three pharmacies in the United States.

A spokesperson for the FDA declined to comment on the ongoing investigation when contacted by this news organization and instead wrote in an email that the agency “will continue to use all available tools to ensure consumers and patients have access to a safe and effective medical product supply.”
 

Old dog, new tricks

This is not the first time that HIV drugs have been targeted for criminal benefit. An analysis published in September 2014 in JAMA highlighted a federal investigation that year into a $32 million dollar scheme to defraud Medicare’s Part D program for HIV drugs and divert them for resale on the black market.

What’s more, prior research and news reports highlight the attractiveness of HIV drug diversion both for the buyer and the seller – not only because of the cost of the drugs themselves but also because of institutional or systemic deficiencies that exclude certain individuals from obtaining treatment through federal initiatives such as the Ryan White/AIDS Drug Assistance program.

In its most recent statement, Gilead reinforced that this practice remains alive and well.

On the buyer side, the company stated, many of the counterfeits originated from suppliers who purchased Gilead HIV medication from individuals after it was first dispensed to them. Unfortunately, the exploitation of individuals with low incomes who experience homelessness or substance use/abuse echoes a pattern whereby HIV patients sell medications to cover personal needs or are forced to buy them on the black market to keep up with their treatment regimens.

On the supply side, Gilead explained that individuals’ medications “are unlawfully resold ... on the secondary market by way of counterfeit supply chain documentation, concealing and fraudulently misrepresenting its origin. All of these counterfeits were sold as though they were legitimate Gilead products.”

But counterfeit pedigrees make it impossible to verify where the products came from, how they have been handled and stored, and what pills are in the bottles – all of which can have dire consequences for patients who ingest them.

The ramifications can be devastating.

“With HIV meds specifically, the worst case scenario would be if the medication is not actually the medication they’re supposed to be on,” said Dr. Heil, reinforcing that the increased safety net provided with viral suppression and against transmission is lost.

Dr. Heil pointed to another significant risk: resistance.

“In a situation like this, where maybe it’s not the full strength of the medication, maybe it’s expired and lost potency or was not stored correctly or is not even the accurate medication, changing those drug level exposures potentially puts the patient at risk for developing resistance to their regimen without them knowing.”

Yet another risk was posed by the replacement of HIV drugs with other medications, such as quetiapine, which increased the risk for life-threatening and irreversible side effects. The lawsuit included a story of a patient who unknowingly took quetiapine after receiving a counterfeit bottle of Biktarvy and could not speak or walk afterward.

Where this tale will ultimately end is unclear. There’s no telling what other activities or bad actors the Justice Department investigation will uncover as it works to unravel the counterfeit network’s activities and deal with its aftermath.

Regardless, clinicians are encouraged to inform HIV patients about the risks associated with counterfeit medications, how to determine whether the drugs they’ve been dispensed are authentic, and to report any product they believe to be counterfeit or to have been tampered with to their doctors, pharmacies, and to Gilead or other drug manufacturers.

“It’s okay to ask questions of your pharmacy about where they get their medications from,” noted Dr. Heil. “If patients have access to an independent pharmacy, it’s a great way for them to have a relationship with their pharmacist.

“We went into this profession to be able to have those conversations with patients,” Dr. Heil said.

The FDA recommends that patients receiving these medications who believe that their drugs may be counterfeit or who experience any adverse effects report the event to FDA’s MedWatch Safety Information and Adverse Event Reporting Program (1-800-FDA-1088 or www.fda.gov/medwatch).

Dr. Heil reported having no relevant financial relationships.

Similar outcomes in patients with ventilator-associated pneumonia (VAP) suggest that antibiotics selected by Gram staining were noninferior to those based on guidelines and also significantly decreased the use of broad-spectrum antibiotics in this patient population.

The findings were published  in JAMA Network Open. The multicenter, open-label, noninferiority, randomized trial, Gram Stain-Guided Antibiotics Choice for VAP (GRACE-VAP), was conducted for 2 years in intensive care units (ICUs) of a dozen tertiary referral hospitals in Japan, from April 1, 2018, through May 31, 2020.

The authors noted in their paper that the 2016 clinical practice guidelines for VAP published by the Infectious Diseases Society of America (IDSA) and the American Thoracic Society recommend antibiotic agents active against both methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa as an empirical treatment. Adherence to these guidelines may lead to overuse of broad-spectrum antibiotic agents and could be associated with the accelerated emergence of antimicrobial-resistant organisms, the authors postulated.

The study sought to answer the question: Can Gram staining be used as an alternative to established guidelines to direct antibiotic use – thereby curbing the use of broad-spectrum antibiotics – without compromising patient safety and clinical outcomes?

A total of 206 patients, with a mean age of 69, took part in the study. The same number of patients were assigned to each arm. Patients aged 15 years or older with a VAP diagnosis and a modified Clinical Pulmonary Infection Score of 5 or higher were included.

Investigators reported that 79 patients (76.7%) responded to antibiotics in the Gram stain-guided group and 74 (71.8%) responded in the guideline-based group (risk difference, 0.05; 95% confidence interval, –0.07 to 0.17; P < .001, for noninferiority).

There was a decrease in antipseudomonal agent use comparing the Gram stain-guided group with the guideline-based group (30.1%; 95% CI, 21.5% to 39.9%; P < .001). There also was a decrease in anti-MRSA agents in the Gram stain-guided group, compared with the guideline-based group (38.8%; 95% CI, 29.4% to 48.9%; P < .001).

The 28-day cumulative incidence of mortality was 13.6% (n = 14) in the Gram stain-guided group versus 17.5% (n = 18) in the guideline-based group. Escalation of antibiotics according to culture results was performed in seven patients (6.8%) in the Gram stain-guided group and in one patient (1.0%) in the guideline-based group. No significant differences in study arms were observed on other measures, such as ICU-free days, ventilator-free days, and adverse events.

The authors concluded that their findings support the use of Gram staining as a strategy to manage infectious diseases and contain the development of multidrug resistant organisms (MDROs) in the setting of critical care.

“In the GRACE-VAP trial, we used the time-honored Gram stain technique as part of the daily management of infectious diseases. We believe that the trial results are acceptable and have the potential to change the strategy of antibiotic choice worldwide,” the authors wrote.

Benjamin D. Galvan MLS(ASCP), CIC, an infection preventionist with a professional background in clinical microbiology, noted that Gram staining is more accessible and significantly less costly than the rapid polymerase chain reaction testing certain institutions use to rapidly identify MDROs to help tailor therapy.

But one of the pitfalls with relying on Gram stain collection to guide antibiotic use is that it is operator dependent and subject to extrinsic factors, like prior antibiotic use, he pointed out.

“If it is not collected, set up, and read properly, the Gram stain is not going to necessarily be reliable” said Mr. Galvan, also a member of the national communications committee for the Association for Professionals in Infection Control and Epidemiology. He added that the sample in the study was not representative of institutions dealing with elevated rates of multidrug resistance.

“Even from their own results, they were looking at hospitals that have a low rate of multidrug resistance,” he said. “It was not clear if MRSA or just Staphylococcus aureus was identified in significant quantities upon review, and they recognized a lower-than-expected number of isolates of Pseudomonas aeruginosa.”

Establishing antibiotic treatment from the results of Gram-stain collection may not be sufficiently comprehensive, he said.

“Generally speaking, basing it (antibiotic therapy) solely off of a Gram stain is not looking at the whole picture,” said Mr. Galvan, noting that the 2016 IDSA guidelines call for an evaluation of the clinical status, including risk, of the individual patient, as well as locally available antibiotic resistance data.

Moreover, the evidence-based IDSA guidelines are in place to help address the issue of antimicrobial resistance trends, already recommending tailoring empiric antibiotic therapy based upon the levels of resistance in the local population, according to Galvan.

While the study suggests that this Gram-stain-driven tailoring of empiric antibiotic therapy may be noninferior to current guidelines in health care settings with low MDRO rates, its utility may not be suitable in hospitals that are already dealing with high rates of MDROs, such as Pseudomonas aeruginosa and Acinetobacter baumannii, or severe clinical cases of VAP, Mr. Galvan explained.

The researchers and Mr. Galvan disclosed no relevant financial relationships.

Similar outcomes in patients with ventilator-associated pneumonia (VAP) suggest that antibiotics selected by Gram staining were noninferior to those based on guidelines and also significantly decreased the use of broad-spectrum antibiotics in this patient population.

The findings were published  in JAMA Network Open. The multicenter, open-label, noninferiority, randomized trial, Gram Stain-Guided Antibiotics Choice for VAP (GRACE-VAP), was conducted for 2 years in intensive care units (ICUs) of a dozen tertiary referral hospitals in Japan, from April 1, 2018, through May 31, 2020.

The authors noted in their paper that the 2016 clinical practice guidelines for VAP published by the Infectious Diseases Society of America (IDSA) and the American Thoracic Society recommend antibiotic agents active against both methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa as an empirical treatment. Adherence to these guidelines may lead to overuse of broad-spectrum antibiotic agents and could be associated with the accelerated emergence of antimicrobial-resistant organisms, the authors postulated.

The study sought to answer the question: Can Gram staining be used as an alternative to established guidelines to direct antibiotic use – thereby curbing the use of broad-spectrum antibiotics – without compromising patient safety and clinical outcomes?

A total of 206 patients, with a mean age of 69, took part in the study. The same number of patients were assigned to each arm. Patients aged 15 years or older with a VAP diagnosis and a modified Clinical Pulmonary Infection Score of 5 or higher were included.

Investigators reported that 79 patients (76.7%) responded to antibiotics in the Gram stain-guided group and 74 (71.8%) responded in the guideline-based group (risk difference, 0.05; 95% confidence interval, –0.07 to 0.17; P < .001, for noninferiority).

There was a decrease in antipseudomonal agent use comparing the Gram stain-guided group with the guideline-based group (30.1%; 95% CI, 21.5% to 39.9%; P < .001). There also was a decrease in anti-MRSA agents in the Gram stain-guided group, compared with the guideline-based group (38.8%; 95% CI, 29.4% to 48.9%; P < .001).

The 28-day cumulative incidence of mortality was 13.6% (n = 14) in the Gram stain-guided group versus 17.5% (n = 18) in the guideline-based group. Escalation of antibiotics according to culture results was performed in seven patients (6.8%) in the Gram stain-guided group and in one patient (1.0%) in the guideline-based group. No significant differences in study arms were observed on other measures, such as ICU-free days, ventilator-free days, and adverse events.

The authors concluded that their findings support the use of Gram staining as a strategy to manage infectious diseases and contain the development of multidrug resistant organisms (MDROs) in the setting of critical care.

“In the GRACE-VAP trial, we used the time-honored Gram stain technique as part of the daily management of infectious diseases. We believe that the trial results are acceptable and have the potential to change the strategy of antibiotic choice worldwide,” the authors wrote.

Benjamin D. Galvan MLS(ASCP), CIC, an infection preventionist with a professional background in clinical microbiology, noted that Gram staining is more accessible and significantly less costly than the rapid polymerase chain reaction testing certain institutions use to rapidly identify MDROs to help tailor therapy.

But one of the pitfalls with relying on Gram stain collection to guide antibiotic use is that it is operator dependent and subject to extrinsic factors, like prior antibiotic use, he pointed out.

“If it is not collected, set up, and read properly, the Gram stain is not going to necessarily be reliable” said Mr. Galvan, also a member of the national communications committee for the Association for Professionals in Infection Control and Epidemiology. He added that the sample in the study was not representative of institutions dealing with elevated rates of multidrug resistance.

“Even from their own results, they were looking at hospitals that have a low rate of multidrug resistance,” he said. “It was not clear if MRSA or just Staphylococcus aureus was identified in significant quantities upon review, and they recognized a lower-than-expected number of isolates of Pseudomonas aeruginosa.”

In recent years, patients with advanced lung cancer have benefited from the advent of immune therapies and genotype-directed therapies –both of which have led to improved survival rates. But what will lung cancer look like in 2030?

Pasi A. Janne, MD, PhD, of the Dana-Farber Cancer Institute, Boston, hopes to see improved access to tumor and blood-based genotyping.

Dr. Janne, who serves as director of the Lowe Center for Thoracic Oncology at Dana-Farber, gave a keynote presentation at the 2022 European Lung Cancer Congress, where he highlighted the need to broaden the scope of targeted therapies, make “great drugs work even better,” improve the ability to treat patients based on risk level, and expand the use of targeted therapies in the adjuvant and neoadjuvant setting to make significant progress in the treatment lung cancer treatment in coming years.

Genotyping is underutilized, he said. A 2019 multicenter study reported at the annual meeting of the American Society of Clinical Oncology showed that only 54% of 1,203 patients underwent testing for EGFR mutations, 22% were tested for EGFR, ALK, ROS1, and BRAF mutations, and only 7% were tested for all biomarkers recommended by National Comprehensive Cancer Network guidelines at the time.

That study also showed that only 45% of patients received biomarker-driven treatment, even when driver mutations were detected.

“Immunotherapy was often prescribed instead of targeted therapy, even when molecular results were available,” Dr. Janne said.

Another study, reported at the 2021 ASCO annual meeting, showed some improvement in testing rates, but still, only 37% of patients were tested for all biomarkers as recommended.

Racial disparities in testing have also been observed. Bruno and colleagues found that any next-generation sequencing was performed in 50.1% of White patients, compared with 39.8% of black patients, and NGS prior to first-line therapy was performed in 35.5% and 25.8%, respectively.

The study, also reported at ASCO in 2021, showed that trial participation was observed among 3.9% of White patients and 1.9% of Black patients.

“The studies really highlight the need for increased testing rates and appropriate utilization of testing results to deliver optimal care to our patients with advanced lung cancer. We have a long way to go. To live the promise and appreciate the promise of precision therapy ... we need to be able to offer this testing to all of our patients with lung cancer,” he said.

Dr. Janne reported relationships with numerous pharmaceutical companies, including consulting, research support and stock ownership. He also receives postmarketing royalties from Dana-Farber Cancer Institute–owned intellectual property on EGFR mutations.
