Two doses of the recombinant zoster vaccine (RZV) are effective against herpes zoster (HZ) for 4 years after vaccination, according to a new study published in Annals of Internal Medicine.

Findings from the prospective cohort study showed that people who received two doses of the vaccine, regardless of when they received their second dose, experienced 79% vaccine effectiveness (VE) during the first year, with effectiveness decreasing to 73% by year 4. By contrast, the rate of effectiveness during the first year was 70% for people who received a single dose, falling to 52% effectiveness by year 4.

The findings also showed that the rate of effectiveness was 65% for those taking corticosteroids.

The study was conducted between 2018 and 2022 using data from the Vaccine Safety Datalink, a collaboration between the US Centers for Disease Control and Prevention (CDC) and nine healthcare systems across the country.

Researchers evaluated the incidence of HZ, as determined by a diagnosis and prescription for antiviral medication within 7 days of diagnosis, and monitored RZV status over time.

The findings may quell fears that waiting too long for the second dose reduces the effectiveness of the herpes vaccine, according to Nicola Klein, MD, PhD, director of the Vaccine Study Center at Kaiser Permanente in Oakland, California, who led the study.

The long-term efficacy of the vaccine is especially important because older adults are now living much longer than in previous years, according to Alexandra Tien, MD, a family physician at Medical Associates of Rhode Island in Providence.

“People live these days into their 80s and even 90s,” Dr. Tien said. “That’s a large number of years to need protection for, so it’s really important to have a long-lasting vaccine.”

The CDC currently recommends two doses of RZV separated by 2-6 months for patients aged 50 years and older. Adults older than 19 years who are immunocompromised should receive two doses of RZV separated by 1-2 months, the agency said.

According to Dr. Klein, research does not show whether VE for RZV wanes after 4 years. But interim findings from another study following people in clinical trials found VE levels remained high after 7 years.

The risk for HZ increases with age, reaching a lifetime risk of 50% among adults aged 85 years. Complications like postherpetic neuralgia (PHN) — characterized by long-term tingling, numbness, and disabling pain at the site of the rash — can interfere with the quality of life and ability to function in older adults. The CDC estimates that up to 18% of people with shingles experience PHN, and the risk increases with age.

Just like with any other vaccine, patients sometimes have concerns about the potential side effects of RZV, said Dr. Tien. But those effects, such as muscle pain, nausea, and fever, are mild compared to shingles.

“I always tell patients, with any vaccine, immunization is one of the biggest bangs for your buck in healthcare because you’re preventing a problem,” Dr. Tien said.

This study was funded by the CDC through contracts with participating sites. Study authors reported no disclosures. Dr. Tien reported no disclosures.

You may have never heard of it, but you may have had it. More evidence points to “long flu” being a real phenomenon, with a large study showing symptoms persist at least 4 weeks or more after some people are hospitalized for the flu.

Researchers compared long flu to long COVID-19 and found long flu happened less often and was less severe overall. This difference could be because the flu mostly affects the lungs whereas COVID can affect any number of organ systems in the body.

The investigators were surprised that both long flu and long COVID were linked to a greater burden of health loss, compared to either initial infection.

“I think COVID and long COVID made us realize that infections have long-term consequences, and often the toll of those long-term consequences is much larger than the toll of acute disease,” said Ziyad Al-Aly, MD, senior author of the study and chief of research and development at the VA St. Louis Health Care System.

“I know, having studied long COVID for the past 4 years, I should not be surprised. But I am in awe of what these infections can do to the long-term health of affected individuals,” said Dr. Al-Aly, who is also a clinical epidemiologist at Washington University in St. Louis.

Dr. Al-Aly and colleagues Yan Xie, PhD, and Taeyoung Choi, MS, analyzed US Department of Veterans Affairs medical records. They compared 81,280 people hospitalized with COVID to 10,985 people hospitalized with the flu before the COVID pandemic. They checked up to 18 months after initial infections to see who developed long flu or long COVID symptoms.

The study was published online in The Lancet Infectious Diseases.

It’s an interesting study, said Aaron E. Glatt, MD, chairman of the Department of Medicine and a hospital epidemiologist at Mount Sinai South Nassau in Oceanside, NY, who was not part of the research.

“There is a concern with many viruses that you can have long-term consequences,” said Dr. Glatt, who is also a fellow of the Infectious Diseases Society of America. He said the possibility of long-term symptoms with the flu is not new, “but it’s nice to have more data.”

People hospitalized with COVID had a 50% higher risk of death during the study period than people hospitalized with the flu. Put another way, for every 100 people admitted to the hospital with COVID, about eight more died than those hospitalized with the flu over the following 18 months. Hospital admissions and admissions to the intensive care unit were also higher in the long COVID group — 20 more people and nine more people, respectively, for every 100 people admitted to the hospital with COVID.

More research is needed, Dr. Glatt said. “With many of these viruses, we don’t understand what they do to the body.” A prospective study to see if antiviral treatments make a difference, for example, would be useful, he noted.

Dr. Al-Aly and colleagues would like to do more studies.

“We need to more deeply understand how and why acute infections cause long-term illness,” he said, noting that he also wants to investigate ways to prevent and treat the long-term effects.

“Much remains to be done, and we are deeply committed to doing our best to develop those answers.”

TOPLINE:

After lung cancer screening (LCS), imaging, and invasive procedures were performed 31.9% and 2.8% of the time, respectively. Complications during invasive procedures occurred in 30.6% of cases. 

METHODOLOGY:

• Researchers analyzed data from 9266 patients aged 55-80 years who completed at least one LCS with low-dose CT (LDCT) between 2014 and 2018.
• This study used data from the PROSPR Lung Consortium.
• Results were compared with findings from the National Lung Screening Trial (NLST), a large study of smokers published in 2011.

TAKEAWAY:

• In total, 2956 patients (31.9%) underwent follow-up imaging, including CT, LDCT, MRI, or PET; 180 (0.02%) had invasive procedures, including needle biopsy, bronchoscopy, mediastinoscopy or mediastinotomy, or thoracoscopy.
• Within 30 days after an invasive diagnostic procedure, 55 of 180 patients (30.6%) experienced complications; 20.6% were major, 8.3% were intermediate, and 1.7% were minor.
• Complication rates after invasive procedures were higher in PROSPR than the NLST (30.6% vs 17.7%).
• Compared with all patients, those with an abnormal LCS were slightly older, more likely to currently smoke, reported more packs of cigarettes smoked daily, and had more comorbid conditions.
• In 2013, the US Preventive Services Task Force recommended annual LCS for certain people who smoke, on the basis of findings from the NLST.

IN PRACTICE:

“We observed higher rates of both invasive procedures and complications than those observed in NLST, highlighting the need for practice-based strategies to assess variations in the quality of care and to prioritize LCS among those patients most likely to receive a net benefit from screening in relation to potential complications and other harms,” the researchers wrote. 

SOURCE:

Katharine A. Rendle, PhD, MSW, MPH, with Perelman School of Medicine, University of Pennsylvania, is the study’s corresponding author. The study was published online in Annals of Internal Medicine.

LIMITATIONS:

This study was retrospective, and data were analyzed using procedural coding. In addition, the NLST based abnormal findings on different criteria from those used in clinical practice (Lung-RADS), making direct comparison of patients difficult. Patients in PROSPR were older, more likely to be currently smoking, and had higher rates of comorbid conditions compared with patients in the NLST. 

DISCLOSURES:

This study was supported by grants from the National Cancer Institute and the Gordon and Betty Moore Foundation.

Medication people with type 2 diabetes use to manage their blood sugar also appears to protect their hearts and kidneys, according to a study in JAMA Network Open. 

These pills, known as sodium-glucose cotransport protein 2 (SGLT2) inhibitors, reduce the amount of blood sugar in a kidney by causing more glucose to be excreted in urine.

Chronic kidney disease (CKD) cannot be cured and often leads to renal failure. SGLT2 inhibitor drugs can help stave off this possibility. Acute kidney disease (AKD), on the other hand, is potentially reversible. It typically occurs after an acute kidney injury, lasts for up to 90 days, and can progress to CKD if left unchecked. 

“There has been a notable absence of targeted pharmacotherapy to offer protection to these patients,” said Vin-Cent Wu, MD, PhD, a nephrologist at National Taiwan University Hospital in Taipei, and an author of the study. 

For the retrospective analysis, Dr. Wu and his colleagues looked at data from more than 230,000 adults with type 2 diabetes whose health records were gathered into a research tool called the TriNetX, a global research database. Patients had been treated for AKD between 2002 and 2022. Major adverse kidney events were noted for 5 years after discharge, which were defined as events which required regular dialysis, major adverse cardiovascular events such as a heart attack or stroke, or death. 

To determine the effects of SGLT2 inhibitors, Dr. Wu and colleagues compared outcomes among 5317 patients with AKD who received the drugs with 5317 similar patients who did not. Members of both groups had lived for at least 90 days after being discharged from the hospital and did not require dialysis during that period. 

After a median follow-up of 2.3 years, more patients who did not receive an SGLT2 inhibitor had died (994 compared with 481) or had endured major stress to their kidneys (1119 compared with 504) or heart (612 compared with 295). The relative reduction in mortality risk for people in the SGLT2-inhibitor arm was 31% (adjusted hazard ratio, 0.69; 95% CI, 0.62-0.77).

Only 2.3% of patients with AKD in the study were prescribed an SGLT2 inhibitor. 

In the United States, approximately 20% of people with type 2 diabetes and CKD receive a SGLT2 inhibitor, according to 2023 research.

“Our study reveals that the prescription rate of SGLT2 inhibitors remains relatively low in clinical practice among patients with type 2 diabetes and AKD,” Dr. Wu told this news organization. “This underscores the need for increased awareness and greater consideration of this critical issue in clinical decision-making.” 

Dr. Wu said that AKD management tends to be conservative and relies on symptom monitoring. He acknowledged that confounders may have influenced the results, and that the use of SGLT2 inhibitors might only be correlated with better results instead of producing a causation effect.

This point was raised by Ayodele Odutayo, MD, DPhil, a nephrologist at the University of Toronto, who was not involved in the study. But despite that caution, Dr. Odutayo said that he found the study to be encouraging overall and broadly in line with known benefits of SGLT2 inhibitors in CKD. 

“The findings are reassuring that the medications work even in people who’ve already had some kidney injury beforehand,” but who are not yet diagnosed with CKD, Dr. Odutayo said. 

“There is vast underuse of these medications in people for whom they are indicated,” perhaps due to clinician concern that the drugs will cause side effects such as low blood pressure or loss of salt and fluid, Dr. Odutayo said. Though those concerns are valid, the benefits of these drugs exceed the risks for most patients with CKD. 

Dr. Wu and Dr. Odutayo report no relevant financial relationships.

Medication people with type 2 diabetes use to manage their blood sugar also appears to protect their hearts and kidneys, according to a study in JAMA Network Open. 

These pills, known as sodium-glucose cotransport protein 2 (SGLT2) inhibitors, reduce the amount of blood sugar in a kidney by causing more glucose to be excreted in urine.

Chronic kidney disease (CKD) cannot be cured and often leads to renal failure. SGLT2 inhibitor drugs can help stave off this possibility. Acute kidney disease (AKD), on the other hand, is potentially reversible. It typically occurs after an acute kidney injury, lasts for up to 90 days, and can progress to CKD if left unchecked. 

“There has been a notable absence of targeted pharmacotherapy to offer protection to these patients,” said Vin-Cent Wu, MD, PhD, a nephrologist at National Taiwan University Hospital in Taipei, and an author of the study. 

For the retrospective analysis, Dr. Wu and his colleagues looked at data from more than 230,000 adults with type 2 diabetes whose health records were gathered into a research tool called the TriNetX, a global research database. Patients had been treated for AKD between 2002 and 2022. Major adverse kidney events were noted for 5 years after discharge, which were defined as events which required regular dialysis, major adverse cardiovascular events such as a heart attack or stroke, or death. 

To determine the effects of SGLT2 inhibitors, Dr. Wu and colleagues compared outcomes among 5317 patients with AKD who received the drugs with 5317 similar patients who did not. Members of both groups had lived for at least 90 days after being discharged from the hospital and did not require dialysis during that period. 

After a median follow-up of 2.3 years, more patients who did not receive an SGLT2 inhibitor had died (994 compared with 481) or had endured major stress to their kidneys (1119 compared with 504) or heart (612 compared with 295). The relative reduction in mortality risk for people in the SGLT2-inhibitor arm was 31% (adjusted hazard ratio, 0.69; 95% CI, 0.62-0.77).

Only 2.3% of patients with AKD in the study were prescribed an SGLT2 inhibitor. 

In the United States, approximately 20% of people with type 2 diabetes and CKD receive a SGLT2 inhibitor, according to 2023 research.

“Our study reveals that the prescription rate of SGLT2 inhibitors remains relatively low in clinical practice among patients with type 2 diabetes and AKD,” Dr. Wu told this news organization. “This underscores the need for increased awareness and greater consideration of this critical issue in clinical decision-making.” 

Dr. Wu said that AKD management tends to be conservative and relies on symptom monitoring. He acknowledged that confounders may have influenced the results, and that the use of SGLT2 inhibitors might only be correlated with better results instead of producing a causation effect.

This point was raised by Ayodele Odutayo, MD, DPhil, a nephrologist at the University of Toronto, who was not involved in the study. But despite that caution, Dr. Odutayo said that he found the study to be encouraging overall and broadly in line with known benefits of SGLT2 inhibitors in CKD. 

“The findings are reassuring that the medications work even in people who’ve already had some kidney injury beforehand,” but who are not yet diagnosed with CKD, Dr. Odutayo said. 

“There is vast underuse of these medications in people for whom they are indicated,” perhaps due to clinician concern that the drugs will cause side effects such as low blood pressure or loss of salt and fluid, Dr. Odutayo said. Though those concerns are valid, the benefits of these drugs exceed the risks for most patients with CKD.

Bromazolam, a street drug that has been detected with increasing frequency in the United States, has reportedly caused protracted seizures, myocardial injury, comas, and multiday intensive care stays in three individuals, new data from the US Centers for Disease Control and Prevention (CDC) showed.

The substance is one of at least a dozen designer benzodiazepines created in the lab but not approved for any therapeutic use. The Center for Forensic Science Research and Education (CFSRE) reported that bromazolam was first detected in 2016 in recreational drugs in Europe and subsequently appeared in the United States.

It is sold under names such as “XLI-268,” “Xanax,” “Fake Xanax,” and “Dope.” Bromazolam may be sold in tablet or powder form, or sometimes as gummies, and is often taken with fentanyl by users.

The CDC report, published in the Morbidity and Mortality Weekly Report (MMWR), described three cases of “previously healthy young adults,” two 25-year-old men and a 20-year-old woman, who took tablets believing it was alprazolam, when it was actually bromazolam and were found unresponsive.

They could not be revived with naloxone and continued to be unresponsive upon arrival at the emergency department. One of the men was hypertensive (152/100 mmHg), tachycardic (heart rate of 124 beats per minute), and hyperthermic (101.7 °F [38.7 °C]) and experienced multiple generalized seizures. He was intubated and admitted to intensive care.

The other man also had an elevated temperature (100.4 °F) and was intubated and admitted to the ICU because of unresponsiveness and multiple generalized seizures.

The woman was also intubated and nonresponsive with focal seizures. All three had elevated troponin levels and had urine tests positive for benzodiazepines.

The first man was intubated for 5 days and discharged after 11 days, while the second man was discharged on the fourth day with mild hearing difficulty.

The woman progressed to status epilepticus despite administration of multiple antiepileptic medications and was in a persistent coma. She was transferred to a second hospital after 11 days and was subsequently lost to follow-up.

Toxicology testing by the Drug Enforcement Administration confirmed the presence of bromazolam (range = 31.1-207 ng/mL), without the presence of fentanyl or any other opioid.

The CDC said that “the constellation of findings reported should prompt close involvement with public health officials and regional poison centers, given the more severe findings in these reported cases compared with those expected from routine benzodiazepine overdoses.” In addition, it noted that clinicians and first responders should “consider bromazolam in cases of patients requiring treatment for seizures, myocardial injury, or hyperthermia after illicit drug use.”
 

Surging Supply, Increased Warnings

In 2022, the CDC warned that the drug was surging in the United States, noting that as of mid-2022, bromazolam was identified in more than 250 toxicology cases submitted to NMS Labs, and that it had been identified in more than 190 toxicology samples tested at CFSRE.

In early 2021, only 1% of samples were positive for bromazolam. By mid-2022, 13% of samples were positive for bromazolam, and 75% of the bromazolam samples were positive for fentanyl.

The combination is sold on the street as benzo-dope.

Health authorities across the globe have been warning about the dangers of designer benzodiazepines, and bromazolam in particular. They’ve noted that the overdose reversal agent naloxone does not combat the effects of a benzodiazepine overdose.

In December 2022, the Canadian province of New Brunswick said that bromazolam had been detected in nine sudden death investigations, and that fentanyl was detected in some of those cases. The provincial government of the Northwest Territories warned in May 2023 that bromazolam had been detected in the region’s drug supply and cautioned against combining it with opioids.

The Indiana Department of Health notified the public, first responders, law enforcement, and clinicians in August 2023 that the drug was increasingly being detected in the state. In the first half of the year, 35 people who had overdosed in Indiana tested positive for bromazolam. The state did not test for the presence of bromazolam before 2023.

According to the MMWR, the law enforcement seizures in the United States of bromazolam increased from no more than three per year during 2016-2018 to 2142 in 2022 and 2913 in 2023.

Illinois has been an area of increased use. Bromazolam-involved deaths increased from 10 in 2021 to 51 in 2022, the CDC researchers reported.

TOPLINE:

Surgery or radiation for advanced prostate cancer may improve survival but at the cost of treatment-related adverse effects, including gastrointestinal (GI) as well as sexual and urinary conditions, that may persist for years, a study of US veterans showed.

METHODOLOGY:

Recent evidence suggested that in men with advanced prostate cancer, local therapy with radical prostatectomy or radiation may improve survival outcomes; however, data on the long-term side effects from these local options were limited.

The retrospective cohort included 5502 men (mean age, 68 years) diagnosed with advanced (T4, N1, and/or M1) prostate cancer.

A total of 1705 men (31%) received initial local treatment, consisting of radical prostatectomy, (55%), radiation (39%), or both (5.6%), while 3797 (69%) opted for initial nonlocal treatment (hormone therapy, chemotherapy, or both). 

The main outcomes were treatment-related adverse effects, including GI, chronic pain, sexual dysfunction, and urinary symptoms, assessed at three timepoints after initial treatment — up to 1 year, between 1 and 2 years, and between 2 and 5 years.

TAKEAWAY:

Overall, 916 men (75%) who had initial local treatment and 897 men (67%) with initial nonlocal therapy reported at least one adverse condition up to 5 years after initial treatment.

In the first year after initial treatment, local therapy was associated with a higher prevalence of GI (9% vs 3%), pain (60% vs 38%), sexual (37% vs 8%), and urinary (46.5% vs 18%) conditions. Men receiving local therapy were more likely to experience GI (adjusted odds ratio [aOR], 4.08), pain (aOR, 1.57), sexual (aOR, 2.96), and urinary (aOR, 2.25) conditions.

Between 2 and 5 years after local therapy, certain conditions remained more prevalent — 7.8% vs 4.2% for GI, 40% vs 13% for sexual, and 40.5% vs 26% for urinary issues. Men receiving local vs nonlocal therapy were more likely to experience GI (aOR, 2.39), sexual (aOR, 3.36), and urinary (aOR, 1.39) issues over the long term.

The researchers found no difference in the prevalence of constitutional conditions such as hot flashes (36.5% vs 34.4%) in the first year following initial local or nonlocal therapy. However, local treatment followed by any secondary treatment was associated with a higher likelihood of developing constitutional conditions at 1-2 years (aOR, 1.50) and 2-5 years (aOR, 1.78) after initial treatment.

IN PRACTICE:

“These results suggest that patients and clinicians should consider the adverse effects of local treatment” alongside the potential for enhanced survival when making treatment decisions in the setting of advanced prostate cancer, the authors explained. Careful informed decision-making by both patients and practitioners is especially important because “there are currently no established guidelines regarding the use of local treatment among men with advanced prostate cancer.”

SOURCE:

The study, with first author Saira Khan, PhD, MPH, Washington University School of Medicine in St. Louis, Missouri, was published online in JAMA Network Open.

LIMITATIONS:

The authors noted that the study was limited by its retrospective design. Men who received local treatment were, on average, younger; older or lesser healthy patients who received local treatment may experience worse adverse effects than observed in the study. The study was limited to US veterans.

DISCLOSURES:

The study was supported by a grant from the US Department of Defense. The authors have no relevant disclosures.

TOPLINE:

In addition to better known risk factors such as diabetes, stroke, heart disease, and depression, findings of a large study suggested vitamin D deficiency, elevated C-reactive protein (CRP) levels, and social isolation increase the risk for young-onset dementia (YOD).

METHODOLOGY:

• The study included 356,052 participants younger than 65 years (mean baseline age, 54.6 years) without dementia from the UK Biobank, an ongoing prospective cohort study.
• Participants underwent a comprehensive baseline assessment, provided biological samples, completed touch screen questionnaires, and underwent a physical examination.
• Researchers identified incident all-cause YOD cases from hospital inpatient registers or death register linkage.
• The researchers detected 39 potential risk factors and grouped them into domains of sociodemographic, genetic, lifestyle, environmental, vitamin D and CRP levels, cardiometabolic, psychiatric, and other factors.
• Researchers analyzed incidence rates of YOD for 5-year age bands starting at age 40 years and separately for men and women.

TAKEAWAY:

• During a mean follow-up of 8.12 years, there were 485 incident YOD cases (incidence rate of 16.8 per 100,000 person-years; 95% CI 15.4-18.3).
• The final analysis identified 15 risk factors associated with significantly higher incidence of YOD, including traditional factors like stroke (hazard ratio [HR], 2.07), heart disease (HR, 1.61), diabetes (HR, 1.65), and depression (HR, 3.25) but also less-recognized risk factors like vitamin D deficiency (< 10 ng/mL; HR, 1.59), high CRP levels (> 1 mg/dL; HR, 1.54), and social isolation (infrequent visits to friends or family; HR, 1.53), with lower socioeconomic status (HR, 1.82), having two apolipoprotein E epsilon-4 alleles (HR, 1.87), orthostatic hypotension, which the authors said may be an early sign of Parkinson dementia or Lewy body dementia (HR, 4.20), and hearing impairment (HR, 1.56) also increasing risk.
• Interestingly, some alcohol use seemed to be protective (moderate or heavy alcohol use had a lower association with YOD than alcohol abstinence, possibly due to the “healthy drinker effect” where people who drink are healthier than abstainers who may have illnesses preventing them from drinking, said the authors), as was higher education level and higher than normative handgrip strength (less strength is a proxy for physical frailty).
• Men with diabetes had higher YOD risk than those without diabetes, while there was no association with diabetes in women; on the other hand, women with high CRP levels had greater YOD risk than those with low levels, while there was no association with CRP in men.

IN PRACTICE:

“While further exploration of these risk factors is necessary to identify potential underlying mechanisms, addressing these modifiable factors may prove effective in mitigating the risk of developing YOD and can be readily integrated in current dementia prevention initiatives,” the investigators wrote.

SOURCE:

The study was led by Stevie Hendriks, PhD, Department of Psychiatry and Neuropsychology, Maastricht University, Maastricht, the Netherlands. It was published online in JAMA Neurology.

LIMITATIONS:

The study was observational and so can’t infer causality. Several factors were based on self-reported data, which might be a source of response bias. Factors not considered in the study, for example, family history of dementia and drug (other than alcohol) use disorder, may have confounded associations. Some factors including orthostatic hypotension had few exposed cases, leading to decreased power to detect associations. Hospital and death records may not have captured all YOD cases. The UK Biobank is overrepresented by healthy and White participants, so results may not be generalizable to other racial and ethnic groups. The analyses only focused on all-cause dementia.

DISCLOSURES:

The study was supported by Alzheimer Netherlands. Hendriks has no relevant conflicts of interest; see paper for disclosures of other authors.

In addition to better known risk factors such as diabetes, stroke, heart disease, and depression, findings of a large study suggested vitamin D deficiency, elevated C-reactive protein (CRP) levels, and social isolation increase the risk for young-onset dementia (YOD).

METHODOLOGY:

• The study included 356,052 participants younger than 65 years (mean baseline age, 54.6 years) without dementia from the UK Biobank, an ongoing prospective cohort study.
• Participants underwent a comprehensive baseline assessment, provided biological samples, completed touch screen questionnaires, and underwent a physical examination.
• Researchers identified incident all-cause YOD cases from hospital inpatient registers or death register linkage.
• The researchers detected 39 potential risk factors and grouped them into domains of sociodemographic, genetic, lifestyle, environmental, vitamin D and CRP levels, cardiometabolic, psychiatric, and other factors.
• Researchers analyzed incidence rates of YOD for 5-year age bands starting at age 40 years and separately for men and women.

TAKEAWAY:

• During a mean follow-up of 8.12 years, there were 485 incident YOD cases (incidence rate of 16.8 per 100,000 person-years; 95% CI 15.4-18.3).
• The final analysis identified 15 risk factors associated with significantly higher incidence of YOD, including traditional factors like stroke (hazard ratio [HR], 2.07), heart disease (HR, 1.61), diabetes (HR, 1.65), and depression (HR, 3.25) but also less-recognized risk factors like vitamin D deficiency (< 10 ng/mL; HR, 1.59), high CRP levels (> 1 mg/dL; HR, 1.54), and social isolation (infrequent visits to friends or family; HR, 1.53), with lower socioeconomic status (HR, 1.82), having two apolipoprotein E epsilon-4 alleles (HR, 1.87), orthostatic hypotension, which the authors said may be an early sign of Parkinson dementia or Lewy body dementia (HR, 4.20), and hearing impairment (HR, 1.56) also increasing risk.
• Interestingly, some alcohol use seemed to be protective (moderate or heavy alcohol use had a lower association with YOD than alcohol abstinence, possibly due to the “healthy drinker effect” where people who drink are healthier than abstainers who may have illnesses preventing them from drinking, said the authors), as was higher education level and higher than normative handgrip strength (less strength is a proxy for physical frailty).
• Men with diabetes had higher YOD risk than those without diabetes, while there was no association with diabetes in women; on the other hand, women with high CRP levels had greater YOD risk than those with low levels, while there was no association with CRP in men.

IN PRACTICE:

“While further exploration of these risk factors is necessary to identify potential underlying mechanisms, addressing these modifiable factors may prove effective in mitigating the risk of developing YOD and can be readily integrated in current dementia prevention initiatives,” the investigators wrote.

SOURCE:

The study was led by Stevie Hendriks, PhD, Department of Psychiatry and Neuropsychology, Maastricht University, Maastricht, the Netherlands. It was published online in JAMA Neurology.

LIMITATIONS:

The study was observational and so can’t infer causality. Several factors were based on self-reported data, which might be a source of response bias. Factors not considered in the study, for example, family history of dementia and drug (other than alcohol) use disorder, may have confounded associations. Some factors including orthostatic hypotension had few exposed cases, leading to decreased power to detect associations. Hospital and death records may not have captured all YOD cases. The UK Biobank is overrepresented by healthy and White participants, so results may not be generalizable to other racial and ethnic groups. The analyses only focused on all-cause dementia.

DISCLOSURES:

The study was supported by Alzheimer Netherlands. Hendriks has no relevant conflicts of interest; see paper for disclosures of other authors.

The plant-based psychoactive compound ibogaine, combined with magnesium to protect the heart, is linked to improvement in severe psychiatric symptoms including depression, anxiety, and functioning in veterans with traumatic brain injury (TBI), early results from a small study showed.

“The most unique findings we observed are the improvements in disability and cognition. At the start of the study, participants had mild to moderate levels of disability. However, a month after treatment, their average disability rating indicated no disability and cognitive testing indicated improvements in concentration and memory,” study investigator Nolan Williams, MD, Stanford University, Stanford, California, told this news organization.

Also noteworthy were improvements across all participants in posttraumatic stress disorder (PTSD), depression, and anxiety — effects that lasted for at least 1 month after treatment, he said.

“These results are remarkable and exceeded our expectations. There is no drug today that can broadly relieve functional and neuropsychiatric symptoms of TBI as we observed with ibogaine,” Dr. Williams added.

The study was published online on January 5, 2024, in Nature Medicine.
 

‘The Storm Lifted’

Ibogaine is derived from the root bark of the Tabernanthe iboga shrub and related plants and is traditionally used in African spiritual and healing ceremonies.

It is known to interact with multiple neurotransmitter systems and has been studied primarily as a treatment of substance use disorders (SUDs). Some studies of ibogaine for SUDs have also noted improvements in self-reported measures of mood.

In the United States, ibogaine is classified as a Schedule I substance, but legal ibogaine treatments are offered in clinics in Canada and Mexico.

Dr. Williams noted that a handful of US veterans who went to Mexico for ibogaine treatment anecdotally reported improvements a variety of aspects of their lives.

The goal of the current study was to characterize those improvements with structured clinical and neurobiological assessments.

Participants included 30 US Special Operations Forces veterans (SOVs) with predominantly mild TBI from combat/blast exposures and psychiatric symptoms and functional limitations. All of them had independently scheduled themselves for treatment with magnesium and ibogaine at a clinic in Mexico.

Before treatment, the veterans had an average disability rating of 30.2 on the World Health Organization Disability Assessment Scale 2.0, equivalent to mild to moderate disability. One month after ibogaine treatment, that rating improved to 5.1, indicating no disability, the researchers reported.

One month after treatment, participants also experienced average reductions of 88% in PTSD symptoms, 87% in depression symptoms, and 81% in anxiety symptoms relative to before treatment.

Neuropsychological testing revealed improved concentration, information processing, memory, and impulsivity. There was also a substantial reduction in suicidal ideation.

“Before the treatment, I was living life in a blizzard with zero visibility and a cold, hopeless, listless feeling. After ibogaine, the storm lifted,” Sean, a 51-year-old veteran from Arizona with six combat deployments who participated in the study, said in a Stanford news release.

There were no serious side effects of ibogaine, and no instances of heart problems associated with the treatment.

Although the study findings are promising, additional research is needed to address some clear limitations, the researchers noted.

“Most importantly, the study was not controlled and so the relative contribution of any therapeutic benefits from non-ibogaine elements of the experience, such as complementary treatments, group activities, coaching, international travel, expectancy, or other nonspecific effects, cannot be determined,” they wrote.

In addition, follow-up was limited to 1 month, and longer-term data are needed to determine durability of the effects.

“We plan to study this compound further, as well as launch future studies to continue to understand how this drug can be used to treat TBI and possibly as a broader neuro-rehab drug. We will work towards a US-based set of trials to confirm efficacy with a multisite design,” said Dr. Williams.
 

Promising, but Very Preliminary

Commenting on the study for this news organization, Ramon Diaz-Arrastia, MD, PhD, professor of neurology and director of the Clinical TBI Research Center, University of Pennsylvania Perelman School of Medicine, Philadelphia, said the results are “promising, but very preliminary.”

Dr. Diaz-Arrastia noted that this was an open-label, nonrandomized study, early phase 2a study with “highly subjective outcome measures and the likelihood of it being a placebo effect is very high.”

Nonetheless, “there is a lot of interest in these ‘psychedelic’ alkaloids, and ibogaine is a good candidate for further study,” Dr. Diaz-Arrastia said.

Also providing perspective, Alan K. Davis, PhD, director of the Center for Psychedelic Drug Research and Education, Ohio State University, Columbus, said “mounting evidence supports the importance of studying this treatment in rigorous clinical trials in the US.”

Dr. Davis and colleagues recently observed that treatment with two naturally occurring psychedelics — ibogaine and 5-MeO-DMT — was associated with reduced depressive and anxiety symptoms in trauma-exposed SOVs, as previously reported by this news organization.

This new study “basically is a replication of what we’ve already published on this topic, and we published data from much larger samples and longer follow up,” said Dr. Davis.

Dr. Davis said it’s “important for the public to know that there are important and serious risks associated with ibogaine therapy, including the possibility of cardiac problems and death. These risks are compounded when people are in clinics or settings where proper screening and medical oversight are not completed.”

“Furthermore, the long-term effectiveness of this treatment is not well established. It may only help in the short term for most people. For many, ongoing clinical aftercare therapy and other forms of treatment may be needed,” Dr. Davis noted.

The study was independently funded by philanthropic gifts from Steve and Genevieve Jurvetson and another anonymous donor. Williams is an inventor on a patent application related to the safety of MISTIC administration as described in the paper and a separate patent related to the use of ibogaine to treat disorders associated with brain aging. Dr. Davis is a board member at Source Resource Foundation and a lead trainer at Fluence. Dr. Diaz-Arrastia has no relevant disclosures.
