As a member of CHEST leadership for years, Bob De Marco, MD, FCCP, ruminated over new, exciting ways to increase support of the philanthropic efforts of the American College of Chest Physicians.

Dr. De Marco knows all too well that the percentage of CHEST members who donate to support CHEST’s philanthropic initiatives is – in a word - underwhelming. For those who are involved, they do so greatly and with their whole selves, but Dr. De Marco believed more could be done.

In the months leading up to the CHEST Annual Meeting 2022 in Nashville, Dr. De Marco discussed fundraising with CHEST staff and was already thinking ahead to CHEST 2023 in Hawai’i.

“That’s when it hit me – we could leverage Hawai’i to get donations and to expose people to CHEST philanthropy,” said Dr. De Marco. “Hawai’i is a dream destination, and that might be the exact motivation it would take to get that first donation from someone.”

Having a good idea is one thing, but making sure it happens requires individual commitment. Dr. DeMarco personally pledged to cover the cost of first-class airfare for two to Hawai’i, hotel accommodations, and registration to CHEST 2023 in Honolulu. For a minimum donation of $250 to CHEST between September and the end of 2022, each donor would be entered into a drawing for a chance to win this dream trip.

“I thought to myself, who wouldn’t want this prize?” said Dr. De Marco.

“You get to go to paradise for free – with a guest – and attend a top tier educational conference. Knowing your entry supported an organization as deserving as CHEST is the cherry on top,” he added.

In launching the Hawai’i trip fundraiser before and during CHEST 2022, attendees from around the world were introduced to CHEST’s philanthropic efforts and its mission to champion lung health. Over $180,000 was donated during this time period, in no small part because of the Hawai’i travel reward.

“I’m happy to say that the fundraiser did a lot better than I expected, and I was elated to see all of the new donors,” said Dr. De Marco.

“It’s my hope that those first-time donors continue their support for all that we do to provide grants – community, research, and diversity – and support CHEST initiatives that impact patient care and change lives.”

During CHEST 2022, Dr. De Marco and other donors reflected on the organization’s philanthropic accomplishments and impact over the past decades.

Former grant recipients were invited to celebrate with donors and speak to what they were able to accomplish because of the support they received.

The celebration also introduced new CHEST initiatives, the First 5 Minutes® program and Bridging Specialties™: Timely Diagnosis for ILD. The former improves patient care through strengthened patient/clinician relationships, and the latter aims to eliminate gaps in diagnosing complex lung diseases like pulmonary fibrosis.

To all who donated to CHEST in 2022, Dr. De Marco said, “A sincere thank you to each and every one of you for helping us fulfill our mission. To the first-time donors, hopefully this will inspire you and your friends to be an active part of the CHEST family.”

And, to the winner of the trip, Dr. De Marco said, “A sincere congratulations and I hope you enjoy beautiful Hawai’i and your time at the meeting.”

Out of the 150+ donors who gave $250 or more to CHEST between September 2022 and the end of 2022, longtime friend of CHEST, Noah Dorsky, was the recipient of two first-class tickets to Hawai’i, hotel accommodations, and registration to CHEST 2023 in Honolulu.

Noah donated specifically to the Mark J. Rosen, MD, Master FCCP Endowment in honor of his late friend, Dr. Mark J. Rosen, who served as CHEST President from 2006 to 2007 and died in 2019.

"Mark was a remarkable doctor and valued life-long friend,” Noah said. “My continued support for CHEST is my way of honoring his memory and how much he meant to me and others."

Dr. Rosen’s distinguished career in pulmonary and critical care medicine spanned more than 4 decades, marked by his deep commitments to medical education and patient care. Before serving as President, Dr. Rosen served on the CHEST Board of Regents for many years. He held positions as Chair or member on numerous CHEST committees, including Education, Nominations, Membership, Marketing, and Finance.

Following his passing, Dr. Rosen’s wife, Ilene, stayed engaged with CHEST by creating the endowment in his name and attending the CHEST Annual Meeting every year to award the Rosen Cup to the winners of the annual CHEST Challenge.

Congratulations, Noah, and thank you for your faithful giving to support the work of CHEST.

Renal impairment in severe falciparum malaria independently predicts a poor outcome in both adults and children.¹ Prompt recognition of malaria-associated renal failure and immediate management with renal replacement therapy reduces mortality and can support the recovery of renal function.^2-4 In addition, adjunctive treatment with acetaminophen has demonstrated improvement in the level of creatinine and reduced progression of kidney injury in a randomized, controlled trial of patients with severe falciparum malaria, particularly in patients with notable intravascular hemolysis.⁵ In this open-label, randomized controlled trial, 62 patients were randomly assigned to receive acetaminophen (n = 31) or no acetaminophen (n = 31).⁵ Antimalarial treatment was with IV artesunate, followed by artemether/lumefantrine. Median (IQR) reduction in creatinine after 72 hours was 23% (37, 18) in patients assigned to acetaminophen vs 14% (29, 0) in patients assigned to no acetaminophen (P = .04).⁵ Acetaminophen showed renoprotection without evidence of safety concerns in patients with severe falciparum malaria, especially those with prominent intravascular hemolysis.

Another study showed consistent findings in other malarial infections with prominent hemolysis, namely, Plasmodium knowlesi malaria. In the PACKNOW open-label, randomized controlled trial, 396 patients aged 12 to 96 years with knowlesi malaria of any severity were randomized to acetaminophen (500 mg or 1000 mg every 6 hours for 72 hours) vs no acetaminophen.⁶ All patients received artesunate and/or oral artemether-lumefantrine for malaria.⁶ No difference was seen overall in patients with acute kidney injury (AKI); however, in those with AKI and hemolysis, creatinine fell by a mean (SD) 34.5% (20.7) in the acetaminophen arm vs 25.9% (15.8) in the control arm (P = .04).⁶ Mixed-effects modeling demonstrated a benefit of acetaminophen at 72 hours (P = .04) and 1 week (P = .002) in patients with severe malaria and with AKI and hemolysis (P = .03 and P = .002, respectively).⁶

Earlier models suggest that the redox cycling of hemoproteins between ferric and ferryl states generates the radical species responsible for severe oxidative damage to the kidneys and subsequent renal impairment.⁷ Reduction of heme-ferryl radicals with therapeutic plasma concentrations of acetaminophen can inhibit this oxidative process.⁷ Rhabdomyolysis models treated with acetaminophen have shown reduced oxidative damage to the kidneys and improved renal functioning, supporting acetaminophen as a potential therapeutic option for disease processes involving hemoprotein-mediated oxidative injury.⁷ In this case report, we discuss the use of acetaminophen as a renoprotective treatment in a patient with renal impairment associated with severe falciparum malaria.

Case Presentation

A 50-year-old man with comorbidities, including hypertension, hyperlipidemia, and chronic kidney disease stage 2, with a baseline creatinine level of 1.4 mg/dL presented with severe falciparum malaria with renal impairment. About 7 months prior, the patient received treatment for his first known case of Plasmodium falciparum (P falciparum) infection. He again contracted P falciparum for a second time after traveling to a malaria-endemic country without taking prophylactic medication before travel.

The patient reported fevers, chills, night sweats, and progressive fatigue. His vital signs recorded a fever of 38.9 ºC with tachycardia and relative hypotension. A thin blood smear revealed P falciparum with approximately 8.5% parasitemia. Laboratory tests confirmed hemolytic anemia and thrombocytopenia reflected by consistently decreased hemoglobin, hematocrit, haptoglobin, and platelets with elevated lactate dehydrogenase and hyperbilirubinemia. Initial renal function testing included an elevated creatinine level of 3.4 mg/dL and an elevated blood urea nitrogen (BUN) level of 45 mg/dL.

The patient received multiple boluses of IV isotonic fluids and a single maximum dose of atovaquone and proguanil before procurement of IV artesunate to manage the malaria. Good response with IV artesunate lowered parasitemia from a high at admission of 10.5% to 0.1% before transitioning to oral artemether and lumefantrine. Concomitantly, the patient’s oliguric renal failure continued to progress early during the hospital stay, and he consented to anticipated dialysis.

To halt progression of his renal injury, salvage renal function, and avoid dialysis, the nephrology team considered acetaminophen 975 mg tablets every 6 hours for 72 hours per the Plewes and colleagues randomized trial.⁵ The patient met the criteria for severe falciparum malaria per the inclusion criteria in the Plewes and colleagues study and was deemed eligible for acetaminophen-based adjunctive treatment. The patient discussed and considered both dialysis and a trial of acetaminophen with the nephrology team, and he understood all the associated risks and benefits, including liver failure. The patient agreed to a trial of acetaminophen with close monitoring of his liver function.

Before starting acetaminophen, the patient’s aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels both measured 53 IU/L or 1.3 times the upper limit of normal (Figure 2).

Discussion

AKI in malaria predominantly occurs with P falciparum infection and represents a significant independent factor in determining morbidity and mortality in adults with severe malaria.⁸ In severe malaria, any hemodynamic compromise likely contributes to the development of acute tubular necrosis (ATN) with insensible losses and poor intake decreasing renal perfusion.⁸ Direct tubular injury from hemoglobinuria or less commonly myoglobinuria from concomitant rhabdomyolysis may also drive malarial AKI.⁸ In addition, proposed mechanisms explaining the pathogenesis of malarial AKI include ATN secondary to disruptions in renal microvasculature, immune dysregulation with proinflammatory reactions within the kidneys, and metabolic disturbances.⁸ Oxidate tubular damage caused by the release of cell-free hemoglobin during red blood cell hemolysis represents 1 form of metabolic derangement possibly responsible for renal impairment.⁸ Acetaminophen administration may help mitigate this oxidative stress, especially in cases of significant hemolysis.⁵

In this case of severe falciparum malaria, the patient demonstrated renal impairment with measured falciparum parasitemia. His creatinine level and BUN appeared to stabilize and improve after 72 hours of acetaminophen administration. A recovery of urine output and improvement in cystatin C occurred during the 72 hours of acetaminophen usage. Despite the patient’s underlying chronic kidney disease, measured proteinuria, and significant changes in renal architecture revealed by ultrasound, he never showed signs of uremia, fluid overload, electrolyte derangements, or acidosis requiring urgent renal replacement therapy.

The patient’s treatment for severe falciparum malaria, including a combination of supportive management, acetaminophen, and IV antimalarials, resulted in the resolution of parasitemia and symptoms with some recovery of renal function without necessitating renal replacement therapy. Maximum daily doses of acetaminophen compared with the control in the Plewes and colleagues acetaminophen trial resulted in moderate increases in aminotransferases not rising to the criteria of hepatotoxicity described in Hy’s law.⁵ Following acetaminophen administration, in this case, AST and ALT levels peaked at 130 and 168 IU/L, 2.8 and 3.8 times the upper limits of normal, respectively. These mild, asymptomatic elevations in aminotransferases recovered to within normal limits, measuring 24 and 13 IU/L at the follow-up.

Conclusions

The demonstrated recovery in renal function, with only a transient, moderate increase in aminotransferases, supports the value of adjunctive acetaminophen as a renoprotective treatment in severe malaria. This simple, readily available treatment may significantly alter the morbidity and mortality associated with severe malaria.

AKI in malaria predominantly occurs with P falciparum infection and represents a significant independent factor in determining morbidity and mortality in adults with severe malaria.⁸ In severe malaria, any hemodynamic compromise likely contributes to the development of acute tubular necrosis (ATN) with insensible losses and poor intake decreasing renal perfusion.⁸ Direct tubular injury from hemoglobinuria or less commonly myoglobinuria from concomitant rhabdomyolysis may also drive malarial AKI.⁸ In addition, proposed mechanisms explaining the pathogenesis of malarial AKI include ATN secondary to disruptions in renal microvasculature, immune dysregulation with proinflammatory reactions within the kidneys, and metabolic disturbances.⁸ Oxidate tubular damage caused by the release of cell-free hemoglobin during red blood cell hemolysis represents 1 form of metabolic derangement possibly responsible for renal impairment.⁸ Acetaminophen administration may help mitigate this oxidative stress, especially in cases of significant hemolysis.⁵

In this case of severe falciparum malaria, the patient demonstrated renal impairment with measured falciparum parasitemia. His creatinine level and BUN appeared to stabilize and improve after 72 hours of acetaminophen administration. A recovery of urine output and improvement in cystatin C occurred during the 72 hours of acetaminophen usage. Despite the patient’s underlying chronic kidney disease, measured proteinuria, and significant changes in renal architecture revealed by ultrasound, he never showed signs of uremia, fluid overload, electrolyte derangements, or acidosis requiring urgent renal replacement therapy.

The patient’s treatment for severe falciparum malaria, including a combination of supportive management, acetaminophen, and IV antimalarials, resulted in the resolution of parasitemia and symptoms with some recovery of renal function without necessitating renal replacement therapy. Maximum daily doses of acetaminophen compared with the control in the Plewes and colleagues acetaminophen trial resulted in moderate increases in aminotransferases not rising to the criteria of hepatotoxicity described in Hy’s law.⁵ Following acetaminophen administration, in this case, AST and ALT levels peaked at 130 and 168 IU/L, 2.8 and 3.8 times the upper limits of normal, respectively. These mild, asymptomatic elevations in aminotransferases recovered to within normal limits, measuring 24 and 13 IU/L at the follow-up.

Conclusions

The demonstrated recovery in renal function, with only a transient, moderate increase in aminotransferases, supports the value of adjunctive acetaminophen as a renoprotective treatment in severe malaria. This simple, readily available treatment may significantly alter the morbidity and mortality associated with severe malaria.

The small size of a new study of the feasibility of tapering conventional synthetic disease-modifying antirheumatic drug (csDMARD) doses to half for patients with rheumatoid arthritis in remission, and then to zero, makes suspect the validity of its finding of no statistical difference between continuing half doses and stopping altogether, according to one rheumatologist’s analysis.

In the open-label, randomized trial of 56 patients, which was published as a research letter in JAMA, more patients in the group that discontinued csDMARDs experienced flares within 1 year than did the half-dose group, but this difference was not statistically significant.

Most patients in the drug-free group did not experience disease flares, the authors note.

“The results show that in this population, a majority of patients remained flare-free for at least a year after csDMARD discontinuation. This highlights a potential for drug-free remission in a subgroup of RA patients, and the data provide a basis for shared decision-making in this patient group. We know that tapering is a common question from patients and thus think that the data are especially clinically relevant,” first author Siri Lillegraven, MD, MPH, PhD, of the Center for Treatment of Rheumatic and Musculoskeletal Diseases at the Diakonhjemmet Hospital, Oslo, said in an interview.

While several studies have demonstrated that patients with RA can maintain remission on lower doses of medication, James O’Dell, MD, chief of the Division of Rheumatology at the University of Nebraska Medical Center, Omaha, urged caution in interpreting these results because the study was so small – just 56 patients. “Every analysis they did favored staying on treatment, but the confidence interval slightly crossed null, so they can’t say [that group] was superior,” Dr. O’Dell said in an interview. He was not involved in the research. “Had this study been double this size and they got the same results, they would have clearly shown that staying on medicines were superior,” he said.

Dr. Lillegraven acknowledged the impact of the trial’s small sample size. “This is a study with a limited study sample, and it is conceivable that a larger study might have shown a statistical difference between the groups,” she said.

In addition to the small number of patients in the study, Dr. O’Dell also noted that this study group was already a selected group of patients who had maintained remission on half-dose therapy for at least 1 year. Even then, “what they showed was that 39% of the patients who they discontinued [then] flared, compared with 17% when they didn’t taper [off medication],” he said. “That’s a pretty important clinical difference.”

While Dr. O’Dell thinks the study was too small to inform practice, he emphasized that tapering off full doses of medications can be beneficial for patients with RA that has been in remission for 6 months or longer. “It seems to take less medicines to keep somebody in remission than it did to get them there in the first place,” he said. “I come out strongly in favor of tapering medications in rheumatoid arthritis patients who are in remission, and that includes tapering and stopping biologics if patients are on conventional therapy,” he added, “but tapering patients off all of their conventional therapy is something that I think is a bridge too far.”

This trial was the second part of the ARCTIC REWIND study, which involved patients with RA that was in sustained remission, per their Disease Activity Score. In the first part of the trial, 160 participants from 10 hospitals in Norway were enrolled and were randomly assigned to either continue their standard csDMARD dosing or taper down to a half dose. Patients whose doses were tapered to a half dose and whose conditions were in remission for 1 year were eligible for the second half the study.

Of the 56 participants who were included, 26 discontinued csDMARD therapy, while 30 continued taking a half dose for 12 months of follow-up. Most patients in both groups had received methotrexate monotherapy (21 in the discontinuation group and 26 in the continued half-dosing group). Triple therapy (methotrexate, sulfasalazine, and hydroxychloroquine) was used by three patients in the discontinuation group and by two in the half-dose group. Two additional patients in the discontinuation group and two in the half-dose group took other mono/duo therapies. Clinic visits occurred every 4 months; visits were more frequent if there was an increase in disease activity. For patients who experienced a disease flare, full-dose csDMARD treatment was resumed.

Ten patients in the discontinuation group experienced flares during 1 year, compared with five patients in the half-dose group. The risk difference between the two groups was not statistically significant (RD, 21.5%; 95% CI, –3.4% to 49.7%). The median time to flare was 179 days in the discontinuation group and 133 days in the half-dose group.

Of those who experienced flares, 8 of 10 patients in the discontinuation group and 2 of 5 in the half-dose group regained remission when full-dose therapy was resumed.

The study was funded by the Research Council of Norway and the South-Eastern Norway Regional Health Authorities. Many of the authors disclosed financial ties to pharmaceutical companies. Dr. O’Dell disclosed no relevant financial relationships.

Despite decades of research, there’s still considerable uncertainty about the comparative effectiveness and safety of analgesics for the treatment of acute low back pain, new research shows.

Higher-quality randomized controlled trials of head-to-head comparisons are needed, study investigator Michael A. Wewege, PhD candidate, research fellow, University of New South Wales and Neuroscience Research Australia, Sydney, said in an interview.

“Until then, doctors should use caution when prescribing analgesic medicines for adults with nonspecific acute low back pain. They should use this new evidence in line with their own expertise and the patient sitting in front of them when making any decision about a medication,” he added.

The findings were published online  in the BMJ. 
 

Poor quality evidence

Analgesics such as ibuprofen, acetaminophen, and codeine are widely used to treat nonspecific low-back pain, which is defined as pain lasting less than 6 weeks, but evidence for the comparative efficacy of these agents is limited.

To fill this knowledge gap, the researchers conducted a systematic review and analysis of controlled trials comparing analgesics with another analgesic, placebo, or no treatment in patients with acute, nonspecific low back pain.

The review involved 98 randomized controlled trials that included 15,134 adults (49% women) aged 30-60 years with pain duration ranging from 24 hours to 21 days. The median baseline pain intensity was 65 on a pain scale of 0-100.

Of the included trials, 39% were placebo controlled, 67% masked both participants and clinicians, and 41% reported industry sponsorship.

The studies compared an analgesic medicine with another analgesic, placebo, or no treatment comprised of usual care or being placed on a wait list.

Study medications, which had to be approved in the United States, Europe, or Australia, included nonsteroidal anti-inflammatory drugs, paracetamol, opioids, anticonvulsants, antidepressants, muscle relaxants, and corticosteroids.

These drugs were administered systemically as a single drug or in combination formulations, at any dose.

Researchers used a network meta-analysis, which combines direct and indirect information across a network of randomized clinical trials to estimate the comparative effectiveness of multiple treatments.

The primary outcomes were reductions in low back pain intensity (measured with a visual analogue scale), numerical rating scale or another ordinal scale, and safety as indicated by the number of participants who had any adverse event.

Investigators found several medications were associated with large reductions in pain intensity, compared with placebo, though with low or very low confidence.

Low or very low confidence was found for reduced pain intensity after treatment with tolperisone (mean difference, −26.1; 95% confidence interval, −34.0 to −18.2), aceclofenac plus tizanidine (mean difference, −26.1; 95% CI, −38.5 to −13.6), pregabalin (mean difference, −24.7; 95% CI, −34.6 to −14.7), and 14 other medicines, compared with placebo, the researchers report.

In addition, they found low or very low confidence for no difference between the effects of several of these medications.

Increased adverse events had moderate to very low confidence with tramadol (risk ratio, 2.6; 95% CI, 1.5-4.5), paracetamol plus sustained release tramadol (RR, 2.4; 95% CI, 1.5-3.8), baclofen (RR, 2.3; 95% CI, 1.5-3.4), and paracetamol plus tramadol (RR, 2.1; 95% CI, 1.3-3.4), compared with placebo, the investigators add.

“These medicines could increase the risk of adverse events, compared with other medicines with moderate to low confidence. Moderate to low confidence was also noted for secondary outcomes and secondary analysis of medicine classes,” the researchers note.

The review suggested 14 additional comparisons favored the treatment over placebo, all with very low confidence except for one with low confidence.

In the 68 trials that included the number of participants reporting an adverse event, there was moderate confidence for increased adverse events with the opioid tramadol (RR, 2.6; 95% CI, 1.5-4.5), paracetamol plus sustained release tramadol (RR, 2.4; 95% CI, 1.5-3.8), paracetamol plus tramadol (RR, 2.1; 95% CI, 1.3-3.4), and low confidence for baclofen (RR, 2.3; 1.5-3.4), compared with placebo.

The review also uncovered moderate to low confidence for secondary outcomes, which included low back-specific function, serious adverse events, and acceptability (number of participants who dropped out).
 

Unexpected findings

The new results were somewhat unexpected, said Mr. Wewege.

“When we set out to do this review, we envisioned the evidence would be a lot more comprehensive. We didn’t think it would be so disconnected and there would be so few trials looking at the different comparisons that would lead us to have low confidence in most of the findings.”

Various factors contributed to this low confidence, he said. One was the risk of bias – about 90% of trials had some concerns or high risk of bias. Another factor was the heterogeneity in effect estimates.

Most of the evidence is based on studies comparing different analgesics to placebo, Mr. Wewege noted. The lack of head-to-head drug comparisons is because “the easiest way to get a drug approved is just to demonstrate it’s better than placebo,” he said.

In addition to these new findings, clinicians should consider a medication’s availability, their own expertise, and patient preferences when selecting an analgesic, said Mr. Wewege. He noted most patients with acute low back pain get better within a few weeks without any intervention.

“Patients should be reassured that things will heal naturally and that they are not going to be in pain forever,” he said.
 

Determining optimal treatment is key

Chris Gilligan, MD, associate chief medical officer, Brigham and Women’s Hospital, and associate professor of anesthesia, Harvard Medical School, both in Boston, said determining which medications are optimal is “key,” as acute low back pain is very common and analgesics are used frequently.

The new review does provide information on which medications have the strongest evidence for pain reduction, said Dr. Gilligan. “On the one hand, it directionally points you towards certain medications, and even certain classes of medication, for comparative effectiveness.”

However, he said, the confidence for this effectiveness is low or very low, “so I wouldn’t overweight it.”

The data on adverse effects, where the confidence is mostly moderate to low, might have more of an influence on prescribing, he said.

“For example, there’s some indication tramadol may be more closely associated with adverse events in patients with acute low back pain and that would add to our caution about using tramadol; it’s not that we would never use it, but [we]would take that into account.”

Dr. Gilligan agrees clinicians should be cautious about prescribing analgesics for low back pain. One reason for being conservative in terms of treatments, he noted, is that “acute low back pain has a very favorable natural history.”

While clinical practice guidelines recommend nonpharmacologic therapies as first- and second-line treatment for acute, nonspecific low back pain, Dr. Gilligan noted that as with drugs, evidence for nondrug therapies also has low or very low confidence.

The study received funding from a 2020 Exercise Physiology Research (Consumables) Grant from the University of New South Wales, which was used to obtain translations of studies published in languages other than English.

Mr. Wewege was supported by a Postgraduate Scholarship from the National Health and Medical Research Council of Australia, a School of Medical Sciences Top-Up Scholarship from the University of New South Wales, and a PhD Supplementary Scholarship from Neuroscience Research Australia. Dr. Gilligan reports that he conducts clinical trials with companies and groups, including the National Institutes of Health related to medications, devices, and procedures for pain.

The review involved 98 randomized controlled trials that included 15,134 adults (49% women) aged 30-60 years with pain duration ranging from 24 hours to 21 days. The median baseline pain intensity was 65 on a pain scale of 0-100.

Of the included trials, 39% were placebo controlled, 67% masked both participants and clinicians, and 41% reported industry sponsorship.

The studies compared an analgesic medicine with another analgesic, placebo, or no treatment comprised of usual care or being placed on a wait list.

Study medications, which had to be approved in the United States, Europe, or Australia, included nonsteroidal anti-inflammatory drugs, paracetamol, opioids, anticonvulsants, antidepressants, muscle relaxants, and corticosteroids.

These drugs were administered systemically as a single drug or in combination formulations, at any dose.

Researchers used a network meta-analysis, which combines direct and indirect information across a network of randomized clinical trials to estimate the comparative effectiveness of multiple treatments.

The primary outcomes were reductions in low back pain intensity (measured with a visual analogue scale), numerical rating scale or another ordinal scale, and safety as indicated by the number of participants who had any adverse event.

Investigators found several medications were associated with large reductions in pain intensity, compared with placebo, though with low or very low confidence.

Low or very low confidence was found for reduced pain intensity after treatment with tolperisone (mean difference, −26.1; 95% confidence interval, −34.0 to −18.2), aceclofenac plus tizanidine (mean difference, −26.1; 95% CI, −38.5 to −13.6), pregabalin (mean difference, −24.7; 95% CI, −34.6 to −14.7), and 14 other medicines, compared with placebo, the researchers report.

In addition, they found low or very low confidence for no difference between the effects of several of these medications.

Increased adverse events had moderate to very low confidence with tramadol (risk ratio, 2.6; 95% CI, 1.5-4.5), paracetamol plus sustained release tramadol (RR, 2.4; 95% CI, 1.5-3.8), baclofen (RR, 2.3; 95% CI, 1.5-3.4), and paracetamol plus tramadol (RR, 2.1; 95% CI, 1.3-3.4), compared with placebo, the investigators add.

“These medicines could increase the risk of adverse events, compared with other medicines with moderate to low confidence. Moderate to low confidence was also noted for secondary outcomes and secondary analysis of medicine classes,” the researchers note.

The review suggested 14 additional comparisons favored the treatment over placebo, all with very low confidence except for one with low confidence.

In the 68 trials that included the number of participants reporting an adverse event, there was moderate confidence for increased adverse events with the opioid tramadol (RR, 2.6; 95% CI, 1.5-4.5), paracetamol plus sustained release tramadol (RR, 2.4; 95% CI, 1.5-3.8), paracetamol plus tramadol (RR, 2.1; 95% CI, 1.3-3.4), and low confidence for baclofen (RR, 2.3; 1.5-3.4), compared with placebo.

The review also uncovered moderate to low confidence for secondary outcomes, which included low back-specific function, serious adverse events, and acceptability (number of participants who dropped out).
 

Unexpected findings

The new results were somewhat unexpected, said Mr. Wewege.

“When we set out to do this review, we envisioned the evidence would be a lot more comprehensive. We didn’t think it would be so disconnected and there would be so few trials looking at the different comparisons that would lead us to have low confidence in most of the findings.”

Various factors contributed to this low confidence, he said. One was the risk of bias – about 90% of trials had some concerns or high risk of bias. Another factor was the heterogeneity in effect estimates.

Most of the evidence is based on studies comparing different analgesics to placebo, Mr. Wewege noted. The lack of head-to-head drug comparisons is because “the easiest way to get a drug approved is just to demonstrate it’s better than placebo,” he said.

In addition to these new findings, clinicians should consider a medication’s availability, their own expertise, and patient preferences when selecting an analgesic, said Mr. Wewege. He noted most patients with acute low back pain get better within a few weeks without any intervention.

“Patients should be reassured that things will heal naturally and that they are not going to be in pain forever,” he said.
 

Determining optimal treatment is key

Chris Gilligan, MD, associate chief medical officer, Brigham and Women’s Hospital, and associate professor of anesthesia, Harvard Medical School, both in Boston, said determining which medications are optimal is “key,” as acute low back pain is very common and analgesics are used frequently.

The new review does provide information on which medications have the strongest evidence for pain reduction, said Dr. Gilligan. “On the one hand, it directionally points you towards certain medications, and even certain classes of medication, for comparative effectiveness.”

However, he said, the confidence for this effectiveness is low or very low, “so I wouldn’t overweight it.”

The data on adverse effects, where the confidence is mostly moderate to low, might have more of an influence on prescribing, he said.

“For example, there’s some indication tramadol may be more closely associated with adverse events in patients with acute low back pain and that would add to our caution about using tramadol; it’s not that we would never use it, but [we]would take that into account.”

Dr. Gilligan agrees clinicians should be cautious about prescribing analgesics for low back pain. One reason for being conservative in terms of treatments, he noted, is that “acute low back pain has a very favorable natural history.”

While clinical practice guidelines recommend nonpharmacologic therapies as first- and second-line treatment for acute, nonspecific low back pain, Dr. Gilligan noted that as with drugs, evidence for nondrug therapies also has low or very low confidence.

The study received funding from a 2020 Exercise Physiology Research (Consumables) Grant from the University of New South Wales, which was used to obtain translations of studies published in languages other than English.

Mr. Wewege was supported by a Postgraduate Scholarship from the National Health and Medical Research Council of Australia, a School of Medical Sciences Top-Up Scholarship from the University of New South Wales, and a PhD Supplementary Scholarship from Neuroscience Research Australia. Dr. Gilligan reports that he conducts clinical trials with companies and groups, including the National Institutes of Health related to medications, devices, and procedures for pain.

Dupilumab, a fully human monoclonal antibody, significantly improved quality of life and respiratory symptoms compared with placebo in a phase 3 trial of more than 900 adults with uncontrolled chronic obstructive pulmonary disease.

In the study, known as the BOREAS trial, dupilumab met its primary and secondary endpoints, with a significant reduction compared with placebo in exacerbations for adults with chronic obstructive pulmonary disease (COPD) that was uncontrolled despite use of the maximal standard-of-care inhaled therapy (triple therapy), according to a press release from manufacturers Regeneron and Sanofi.

Dupilumab, which inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) pathways, is currently approved in multiple countries for certain patients with conditions including atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps, eosinophilic esophagitis, or prurigo nodularis in different age groups. The drug is not an immunosuppressant, and would be the first biologic approved for COPD, according to the manufacturers.

In the BOREAS trial, 468 adults with COPD who were current or former smokers aged 40-80 years were randomized to dupilumab and 471 to placebo; both groups continued to receive maximal standard of care.

Over 52 weeks, patients in the dupilumab group experienced a 30% reduction in moderate to severe COPD exacerbations compared with placebo (P = .0005).

In addition, patients treated with dupilumab met the key secondary endpoints of significant improvement in lung function from baseline to 12 weeks compared with placebo (160 mL vs. 77 mL, P < .0001); this difference persisted at 52 weeks (P = .0003).

Dupilumab also met endpoints for improvement in patient-reported health-related quality of life based on the St. George’s Respiratory Questionnaire (SGRQ) and reduction in the severity of respiratory symptoms of COPD based on the Evaluation Respiratory Symptoms: COPD (E-RS: COPD) Scale, according to the companies’ statement.

The results represent a previously unreported magnitude of improvement for COPD patients treated with a biologic, principal investigator George D. Yancopoulos, MD, said in the statement. “These results also validate the role type 2 inflammation plays in driving COPD in these patients, advancing the scientific community’s understanding of the underlying biology of this disease,” he added.

The safety results in the BOREAS trial were generally consistent with the known safety profile of Dupixent in its approved indications. Overall adverse event rates were similar for dupilumab and placebo patients (77% and 76%, respectively) and the overall safety profiles were consistent with the currently approved dupilumab indications, according to the manufacturers.

The adverse events that were more common in dupilumab patients compared with placebo patients were headache (8.1% vs. 6.8%), diarrhea (5.3% vs. 3.6%), and back pain (5.1% vs. 3.4%).

Adverse events leading to deaths were similar between the groups (1.7% in placebo patients and 1.5% in dupilumab patients).

Complete safety and efficacy results from the BOREAS trial are scheduled to be presented in a future scientific forum, and a second phase 3 trial of dupilumab for COPD, known as NOTUS, is ongoing, with data expected in 2024, according to the manufacturers.

The Boreas trial was sponsored by Sanofi and Regeneron Pharmaceuticals.

This is Dr. JoAnn Manson, professor of medicine at Harvard Medical School and Brigham and Women’s Hospital. I’d like to talk with you about a recent report on the American Heart Association Life’s Essential 8 metric and its association with both life expectancy and health span or life expectancy free of chronic diseases such as cardiovascular disease (CVD), cancer, diabetes, and dementia.

This study leveraged the UK Biobank and included more than 135,000 U.K. adults with a mean age of 55. The AHA metric was defined as including the following lifestyle behavioral factors:

• Not smoking.
• Regular physical activity.
• Healthy weight.
• Healthy diet.
• Healthy sleep (defined as an average of 7-9 hours nightly).
• Blood pressure in a healthy range.
• Blood glucose in a healthy range.
• Non-HDL cholesterol in a healthy range.

This study was just published in JAMA Internal Medicine. I’d like to acknowledge that I’m a coauthor of this study, along with my colleagues at Tulane.

We divided the study population into three groups: those with low, moderate, and high scores on the Life’s Essential 8 metric – low, moderate, and high cardiovascular health. Overall, the average life expectancy free of chronic disease was estimated to be age 50, with 25 additional years in men and 30 additional years in women.

We saw large differences across the Life’s Essential 8 metric group. Men with high cardiovascular health scores tended to have an additional 7 years of life expectancy free of chronic disease, compared with those who had poorer scores. In women, the difference was about 9.5 years between high scores and lower scores. Also, the number of years lived with chronic disease was compressed in those with high cardiovascular health scores. They tended to have fewer years living with those chronic diseases but more years living free of chronic diseases.

We were interested in how these results might differ by socioeconomic status, educational level, and income level, as well as the Townsend deprivation index. We were intrigued by the finding that the gain in life expectancy free of chronic disease was very similar across all socioeconomic strata – those with lower education and lower income gained as much in terms of chronic disease–free life expectancy as those who were in the higher socioeconomic strata.

Overall, the findings make a compelling case for the importance of lifestyle factors in extending health span and years free of chronic disease. It can be motivating to tell our patients that a healthy lifestyle not only extends life expectancy but also extends years of health free of chronic disease.

Nonetheless, we do have many disparities in life expectancy and health span. So it will be very important to population health to narrow those health disparities through education about the importance of lifestyle factors, more research on implementation of lifestyle factors and behaviors, and public policy to make a healthy lifestyle both affordable and accessible to all people across all of these socioeconomic groups.

Thank you so much for your attention.

Childhood autism rates have ticked up once again, according to the latest data from Centers for Disease Control and Prevention.

According to the CDC, 1 in 36 (2.8%) 8-year-old children have been identified with autism spectrum disorder (ASD) – up from the previous 2018 estimate of 1 in 44 (2.3%).

The updated data come from 11 communities in the Autism and Developmental Disabilities Monitoring (ADDM) network and were published online in Morbidity and Mortality Weekly Report.

A separate report in the MMWR on 4-year-old children in the same 11 communities highlights the impact of COVID-19, showing disruptions in progress in early autism detection.

In the early months of the pandemic, 4-year-old children were less likely to have an evaluation or be identified with ASD than 8-year-old children when they were the same age. This coincides with interruptions in childcare and health care services during the COVID-19 pandemic.

“Disruptions due to the pandemic in the timely evaluation of children and delays in connecting children to the services and support they need could have long-lasting effects,” Karen Remley, MD, director of CDC’s National Center on Birth Defects and Developmental Disabilities, said in a statement.

“The data in this report can help communities better understand how the pandemic impacted early identification of autism in young children and anticipate future needs as these children get older,” Dr. Remley noted.
 

Shifting demographics

The latest data also show that ASD prevalence among Asian, Black, and Hispanic children was at least 30% higher in 2020 than in 2018, and ASD prevalence among White children was 14.6% higher than in 2018.

For the first time, according to the CDC, the percentage of 8-year-old Asian/Pacific Islander (3.3%), Hispanic (3.2%) and Black (2.9%) children identified with autism was higher than the percentage of 8-year-old White children (2.4%).

This is the opposite of racial and ethnic differences seen in previous ADDM reports for 8-year-olds. These shifts may reflect improved screening, awareness, and access to services among historically underserved groups, the CDC said.

Disparities for co-occurring intellectual disability have also persisted, with a higher percentage of Black children with autism identified with intellectual disability compared with White, Hispanic, or Asian/Pacific Islander children with autism. These differences could relate in part to access to services that diagnose and support children with autism, the CDC noted.

Overall, autism prevalence within the 11 ADDM communities was nearly four times higher for boys than girls. However, it’s the first time that the prevalence of autism among 8-year-old girls has topped 1%.
 

Community differences

Autism prevalence in the 11 ADDM communities ranged from 1 in 43 (2.3%) children in Maryland to 1 in 22 (4.5%) in California – variations that could be due to how communities identify children with autism.

This variability affords an opportunity to compare local policies and models for delivering diagnostic and interventional services that could enhance autism identification and provide more comprehensive support to people with autism, the CDC said.

These differences could relate in part to access to services that diagnose and support children with autism, the CDC noted.

Overall, autism prevalence within the 11 ADDM communities was nearly four times higher for boys than girls. However, it’s the first time that the prevalence of autism among 8-year-old girls has topped 1%.
 

Community differences

Autism prevalence in the 11 ADDM communities ranged from 1 in 43 (2.3%) children in Maryland to 1 in 22 (4.5%) in California – variations that could be due to how communities identify children with autism.

This variability affords an opportunity to compare local policies and models for delivering diagnostic and interventional services that could enhance autism identification and provide more comprehensive support to people with autism, the CDC said.

Cases of acquired hypogammaglobulinemia are expected to rise, as patients live longer with such B-cell malignancies as chronic lymphocytic leukemia (CLL), non-Hodgkin lymphoma, and multiple myeloma. But there’s a striking shortage of research into the best prophylactic approaches to prevent infections, a new systematic review and meta-analysis showed.

Researchers found just 22 randomized controlled studies into prophylactic strategies, with several of them conducted prior to 2000. According to the report, published in Blood Advances, the studies together only evaluated a few thousand participants.

Reliable findings are so sparse that study coauthor Zoe McQuilten, MBBS, PhD, MD, a hematologist at Monash University, Melbourne, said “we simply don’t know” which preventive strategy is most effective. This is especially worrisome because more patients will survive their cancers and “be at risk of infection or have significant cytopenias and will experience impaired quality of life as a result,” she said in an interview.

The study authors launched the analysis to better understand the evidence regarding infection prevention and to guide the development of clinical trials, study coauthor Robert Weinkove, MBBS, PhD, a hematologist at Malaghan Institute of Medical Research, Wellington, New Zealand, said in an interview.

As he explained, targeted therapies have revolutionized the treatment of some B-cell cancers. They also have boosted the number of patients who survive the diseases yet still have profound hypogammaglobulinemia.

“Indeed, we may soon reach the point at which infection, and not tumor progression, is the leading cause of death for patients with certain B-cell cancers,” he said. “The evidence base for managing hypogammaglobulinemia is largely based on randomized trials of immunoglobulin replacement conducted in the 1980s and early 1990s, before the advent of B cell–targeted therapies. Immunoglobulin replacement is a costly intervention, and many countries are facing a shortage of immunoglobulin.”

The report authors identified 22 total randomized controlled trials, including one led by Dr. McQuilten: 8 studies into prophylactic immunoglobulin (n = 370; all but 1 study published prior to 2000), 5 into prophylactic antibiotics (n = 1,587), 7 into vaccination (n = 3,996), and 1 comparing immunoglobulin versus antibiotics (n = 60).

No evidence was found to support a lowering of risk by prophylactic antibiotics, although they caused adverse events.

Prophylactic immunoglobulin also caused adverse events, but a meta-analysis found that it reduced the risk of clinically documented infection by 28% (n = 2 trials; relative risk, 0.72; 95% confidence interval, 0.54-0.96). Three trials reported adverse events and found a higher risk overall (RR, 2.23; 95% CI, 1.67-2.99).

Varicella zoster virus vaccination reduced the risk of one or more infections by 63% (n = 5 trials, RR, 0.37; 95% CI, 0.30-0.45, n = 3,515). Prophylactic antibiotics did not reduce the risk.

No intervention reduced all-cause mortality.

“Our findings should be interpreted with caution, Dr. McQuilten said, “because of the low number of patients, high risk of bias in the included studies, and lack of contemporary data applicable to the current standard of care for such patients.”

The lack of useful data is surprising, she said, especially considering “how commonly these interventions are used in current clinical practice and the cost and supply constraints for immunoglobulin. Given the variation in international guidelines, rising global demand and cost of immunoglobulin, and concerns regarding antimicrobial resistance, more evidence is needed to inform infection prevention strategies for this patient population.”

More data is expected soon. One ongoing study is examining intravenous immunoglobulin versus placebo in patients with CLL. It’s expected to be completed in September 2023.

What should clinicians do for now? “Given the lack of a proven survival benefit in favor of prophylactic immunoglobulin replacement, one strategy is to maximize use of vaccination and to educate both patients and clinicians regarding the need for early treatment of infections,” Dr. Weinkove said. “For people who have recurrent or severe infections despite these measures, both immunoglobulin replacement and prophylactic antibiotics are clinical options. It would be reasonable to take account of patient preference, logistical considerations, and reimbursement and availability in deciding between these options.”

He added that, “for people with severe hypogammaglobulinemia who experience recurrent or severe infections despite prophylactic antibiotics, switching to immunoglobulin replacement would be appropriate. We advocate enrollment in clinical trials, if possible.”

In an interview, Juthaporn Cowan, MD, PhD, an infectious disease physician with the University of Ottawa, said many patients with B-cell lymphomas develop acquired hypogammaglobulinemia. “Patients tend to get prolonged colds, frequent sinusitis, bronchitis, or pneumonia. Some can end up with severe infection. Many patients told me that, even though their cancer is cured or in remission, quality of life is still quite poor due to these infections and fatigue.”

Dr. Cowan said the new report is somewhat useful, although “concluding that vaccination reduces infection is misleading. Vaccination reduces the infection that patients were vaccinated against. Patients who received Shingrix will have less shingles but will continue to have bronchitis and other infections.”

As for advice for clinicians, she said preventing acquired hypogammaglobulinemia is difficult since it can be caused by the malignancies, by treatment, or both. “The other item to consider is that we do not know how long we should continue [immunoglobulin] treatment in these patients. I have a patient post CAR [chimeric antigen receptor] T therapy who still does not have B-cell 5-6 years after CAR T, while I have lymphoma patients who could safely discontinue [immunoglobulin] treatment in a few years.”

Dr. Cowan added that patients on immunoglobulin treatment can still get opportunistic infections from cytomegalovirus or herpes simplex virus “because the mechanism of host defense against these infections is different. Antimicrobial prophylaxis should still be considered as vaccination is not available for every single potential opportunistic infection.”

Australia funded the research through the National Blood Authority. Dr. McQuilten and Dr. Weinkove reported no disclosures. Other report authors disclosed ties with Aegros, CSL Behring, Janssen, AbbVie, and BeiGene. Monash University has received funding for unrelated projects from CSL Behring. Dr. Cowan reports honoraria from Takeda, CSL Behring, Octapharma, GlaxoSmithKline, Merck, and AstraZeneca.

Among patients who undergo forceps-assisted vaginal delivery, obesity does not appear to be associated with increased risk for complications such as injuries to the anal sphincter or the need for their babies to be admitted to the neonatal intensive care unit, researchers have found.

But obesity does appear to increase the chances that when physicians attempt operative vaginal delivery with either forceps or a vacuum, patients will wind up undergoing cesarean delivery, another study found.

Taken together, the new data may help inform physicians’ decisions about when to consider operative vaginal delivery as an alternative to emergency cesarean births.

A prospective study showed that failed operative vaginal delivery – that is, a cesarean delivery after an attempted operative vaginal delivery – occurred for 10.1% of patients with obesity and 4.2% of those without obesity.

Researchers presented the findings at the meeting sponsored by the Society for Maternal-Fetal Medicine.

“We want to really try to reduce the rate of C-sections and primary cesarean deliveries. One of the ways to do that is to attempt operative vaginal delivery,” said Marissa Platner, MD, assistant professor of maternal-fetal medicine at Emory University School of Medicine, Atlanta, who was not involved in the new research.

Data on how obesity influences risks with operative vaginal delivery have been limited and mixed, the researchers said.

To examine how often attempted operative vaginal delivery fails in patients with obesity, Jennifer Grasch, MD, a maternal-fetal medicine fellow at the Ohio State University Wexner Medical Center, Columbus, and her colleagues conducted a secondary analysis of data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be, which included more than 10,000 participants.

“We know that cesarean sections among people with obesity are associated with increased complications, such as higher rates of infection and wound complications, than for people with lower BMI,” Dr. Grasch said. “Operative vaginal delivery can be an alternative to cesarean delivery in some situations, so we were interested in whether attempted operative vaginal delivery was also associated with higher rates of complications in individuals with obesity than those without obesity.”

The researchers focused on 791 patients with an attempted operative vaginal delivery. About 40% had a BMI of 30 or greater. Clinicians used a vacuum in approximately 60% of the attempts.

After an attempted vacuum-assisted delivery, neonatal morbidity was more common for infants whose mothers had obesity than for those whose mothers did not (32.7% vs. 22.3%; adjusted odds ratio, 1.61 [1.07-2.43]). Neonatal morbidity did not differ by obesity status following forceps-attempted delivery. Other adverse outcomes, including measures of maternal morbidity, did not significantly differ by obesity status, according to the researchers.
 

Choice may come down to experience

Several factors influence whether a clinician chooses forceps- or vacuum-assisted delivery or cesarean delivery, “but one of the most important is experience,” Dr. Grasch said. “Complication rates with both forms of operative vaginal delivery are low, yet there has been a trend toward lower rates of both in the last few decades.”

Elizabeth Cochrane, MD, a maternal-fetal medicine fellow at Mount Sinai Hospital, New York, and her colleagues investigated the relationship between obesity and adverse outcomes among patients with forceps-assisted vaginal deliveries.

The researchers analyzed data from 897 patients who underwent a forceps-assisted vaginal delivery between 2017 and 2021; 29% had a BMI of 30 or greater.

Injuries to the anal sphincter – which can lead to fecal incontinence – occurred in 18.7% of patients without obesity and in 17.7% of those with obesity. Admission to the neonatal intensive care unit occurred in 11.5% of patients without obesity and in 12.3% of patients with obesity. The differences were not statistically significant.

The bottom line: For forceps-assisted vaginal delivery, “obesity does not appear to be associated with increased rates” of adverse outcomes for mothers or newborns, the researchers concluded.
 

Reassuring data

The study by Dr. Cochrane’s group “provides helpful information for providers to be reassured when they are performing forceps deliveries” for patients with obesity, Dr. Platner said.

Rates of obesity have risen in the United States, and physicians often wonder whether a patient with obesity could be a candidate for forceps-assisted delivery, Dr. Cochrane said. In 2019, 29% of women had obesity before becoming pregnant.

“It all really comes down to how comfortable the provider is in that skill set and also the overall clinical scenario,” she said. “Sometimes an operative delivery with forceps or a vacuum can be the fastest way to deliver a baby when there is acute concern for maternal decompensation or fetal decompensation.”

The alternative is an emergency cesarean delivery. Given that those operations can be riskier and more difficult for patients with higher BMIs, a forceps-assisted delivery may be “an interesting alternative to emergency caesarean sections, as long as it is in an appropriate clinical setting with providers who feel very confident and comfortable using those devices,” Dr. Cochrane said.

Disparities in statin use in minority populations persist regardless of insurance status and 10-year atherosclerotic cardiovascular disease risk.

Those are among the findings of a study that sampled a national population database and has provided robust data and granular details on those disparities.

The researchers reported in JAMA Cardiology that the overall prevalence of statin use was 25.5%, and that it varied significantly between defined ethnic groups: 20% for Blacks, 15.4% for Hispanics, and 27.9% for Whites (P < .001). Statin use rates by Asian participants, at 25.5%, didn’t differ significantly from use by Whites.

“We know that there are racial and ethnic disparities in the use of guideline-indicated statins after having established heart disease, but it was unknown if these disparities existed in the use of guideline-indicated statins for prevention of heart disease in those who just have risk factors,” lead author Joshua Jacobs, PharmD, a clinical pharmacist of cardiovascular medicine at University of Utah Intermountain Healthcare, said in written comments. “Additionally, race is included in the guideline-recommended risk factor calculation in an effort to reduce these disparities.”

Dr. Jacobs and colleagues evaluated statins for use in primary prevention, building upon previous single-center or diabetes-only cohort studies. What makes their study different from previous studies evaluating disparities in statin use is its use of temporal trends or current 10-year predicted ASCVD risk categorization, he said.

Using data from the National Health and Nutrition Examination Survey (NHANES), the researchers performed a serial, cross-sectional analysis of 3,417 participants that they said represented 39.4 million U.S. adults after applying sampling weights for age, gender, and race and ethnicity. In the weighted sample, 62.2% were men. In terms of self-reported race and ethnicity, 4.2% were of Asian descent, 12.7% were Black, 10.1% were Hispanic, and 73% were White.

Study participants completed a standardized questionnaire given by trained interviewers and also went to mobile examination centers where physical, anthropomorphic, and laboratory measurements, including height, weight, LDL cholesterol, and fasting blood glucose were collected. Pill bottle review also verified participants’ self-reported medication use.

The study noted that for primary prevention of atherosclerotic cardiovascular disease (ASCVD), the 2018 American College of Cardiology/American Heart Association Guideline recommends statins for, among other patient factors, elevated 10-year predicted ASCVD risk. The study divided ASCVD risk strata into three groups – 5% to less than 7.5%, 7.5% to less than 20%, and more than 20% – based on the 2018 ACC/AHA guideline and used pooled cohort equation to calculate 10-year ASCVD risk, which the guideline endorses.

Gaps persist despite ASCVD risk

The analysis found no statistically significant difference within each ASCVD risk strata between the White and Asian groups. But although statin use increased proportionately across each higher risk group, the gap widened noticeably in the highest risk group (more than 20% 10-year risk) between Whites, used as the reference at 37.6%, and Blacks (23.8%; prevalence ratio, .90; 95% confidence interval, .82-.98) and Hispanics (23.9%; PR, .90; 95% CI, .81-.99).

The study also evaluated a number of social determinants of health factors. Health insurance and access to routine health care were significantly associated with greater statin use in Black, Hispanic, and White participants; marital status and food insecurity were not. However, even when variables such as education, household income, and health insurance were applied, statin use was still significantly higher in Whites than in Blacks and Hispanics. For those with health insurance, statin use was 28.6% (95% CI, 25-32), 21.1% (95% CI, 17.3-25.4) and 19.9% (95% CI, 15.9-24.5), respectively.

The study noted that the pooled cohort equation-guided approach to statins for primary prevention, which the 2018 ACC/AHA guideline endorsed, should promote greater use of statins among Black patients. “Equitable use of statin therapy for prevention of heart disease is needed for Black and Hispanic adults,” Dr. Jacobs said. “Improvements in access to care, such as having a routine primary care clinician and health insurance, may decrease these health disparities.”

A goal of the study was to identify if disparities in statin use held up across different risk groups, senior author Ambarish Pandey, MD, said in an interview. Use of the NHANES data makes this study unique among analyses of statin use disparities, he said.

“A lot of the work that has been done previously has focused on secondary prevention among patients who have atherosclerotic cardiovascular disease or have focused on single-center or hospital-based cohorts and have not really focused on a national representative cohort like NHANES,” said Dr. Pandey, of the UT Southwestern Medical Center, Dallas.

The next step is to do community-based participatory research focusing on different implementation strategies to increase the uptake of preventive statin use among Black and Hispanic communities, Dr. Jacobs said.
