Listening to Mozart helps tame epilepsy
Listening to Mozart’s piano music improves epilepsy, according to a meta-analysis presented at the virtual congress of the European College of Neuropsychopharmacology.
The results of the meta-analysis of 12 published studies of the so-called Mozart Effect that met rigorous Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines demonstrate that listening to Mozart results in significant reductions in both epileptic seizure frequency and interictal epileptiform discharges (IED), compared with baseline.
The benefits were apparent during and after even a single listening session, although the effect was greater with regular daily listening sessions, according to Gianluca Sesso, MD, a resident in child and adolescent psychiatry at the University of Pisa (Italy.)
“Obviously other music may have similar effects, but it may be that Mozart’s sonatas have distinctive rhythmic structures which are particularly suited to working on epilepsy,” he speculated, adding that the mechanism involved in the Mozart Effect on brain systems remains unclear.
“The highly consistent results of our meta-analysis strongly suggest that music-based neurostimulation may improve the clinical outcome in epilepsy by reducing seizures and IED, and thus deserves to be included in the set of nonpharmacologic complementary approaches for treating epilepsy,” Dr. Sesso added.
Four studies examined the effects of listening to Mozart’s Sonata for Two Pianos in D, K.448, the most-studied piece of music as a treatment for epilepsy. The data documented a 31% reduction in seizure frequency and 28% decrease in IED during a single listen, and a 79% reduction in IED after long-term Mozart music therapy. Similarly, studies demonstrated that listening to a set of Mozart’s compositions resulted in a 36% reduction in IED during and 38% decrease after a single listen, while regular listening in a prolonged treatment period resulted in a 66% reduction in seizure frequency from baseline.
Several studies compared the benefits of listening to K. 488 with those accrued through listening to Piano Sonata No. 16 in C major, K. 545. There was no significant difference between the two, according to Dr. Sesso.
He reported having no financial conflicts regarding his meta-analysis, carried out free of commercial support.
The full details of the meta-analysis were recently published in Clinical Neurophysiology.

Women with MS may have increased subclinical disease activity during pregnancy
The increase in sNfL is independent of relapses, which suggests that patients have increased subclinical disease activity during this period, according to the researchers.
When the investigators controlled their data for exposure to disease-modifying therapy (DMT), the effect of pregnancy on sNfL was no longer evident. These data were presented said at the Joint European Committee for Treatment and Research in Multiple Sclerosis–Americas Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS-ACTRIMS) 2020, this year known as MSVirtual2020.
The results suggest that “sNfL may qualify as a sensitive and minimally invasive measure of disease activity in pregnancy,” said Özgür Yaldizli, MD, consultant neurologist at University Hospital Basel (Switzerland). “Strategies allowing the continuation of DMT during pregnancy may be warranted.”
MS preferentially affects women in their reproductive years, said Dr. Yaldizli. Almost one-third of women with MS become pregnant after they receive their diagnosis. A decrease in disease activity is typical in the third trimester, as is an increase in relapse frequency post partum.
DMTs reduce the risk of relapse, but have potential side effects for the woman and the fetus. Some DMTs are immunosuppressants, and they increase the risk of infection during pregnancy. Other DMTs may harm the development of the fetus, particularly if administered early during pregnancy.
“There is an urgent need to identify patients with high disease activity during pregnancy,” said Dr. Yaldizli. Increased levels of NfL, a specific biomarker of neuroaxonal injury, are associated with relapses, MRI activity, and disability worsening among patients with MS. Response to DMT is associated with decreased NfL levels. But few data about sNfL during pregnancy or post partum are available.
Relapses were associated with increased sNfL
Dr. Yaldizli and colleagues examined data from the Swiss MS Cohort Study to describe DMT use before, during, and after pregnancy. They also sought to assess sNfL as a marker of disease activity during and after pregnancy and to evaluate whether interrupting DMT because of pregnancy leads to increased sNfL levels.
Eligible participants had prospectively documented pregnancies, and Dr. Yaldizli’s group excluded pregnancies with early termination from their analysis. Serum samples were collected every 6 or 12 months and analyzed using the Simoa NF-light assay. The investigators used univariable and multivariable mixed-effects models to investigate associations between clinical characteristics and longitudinal sNfL levels in women before pregnancy, during pregnancy, and post partum.
Dr. Yaldizli and colleagues included 72 pregnancies in 63 patients with relapsing MS in their analysis. Nine patients had two pregnancies during follow-up. The population’s median age was 31.4 years, and median disease duration was 7.1 years. Median Expanded Disability Status Scale (EDSS) score at last visit before birth was 1.5. Median follow-up time was 6 years.
Most patients were treated with DMT before or during pregnancy. For most patients (39), fingolimod or natalizumab was the last DMT given before birth. Four patients did not use DMT before, during, or after pregnancy. In 14 pregnancies, the patient continued DMT for more than 6 months.
The univariable analysis showed that sNfL levels were 22% higher during pregnancy, compared with outside the pregnancy and postpartum period. The investigators recorded 29 relapses during the pregnancy and postpartum period. Relapses were more likely to occur during the first trimester and the first 3 months post partum. In the multivariable analysis, relapses that occurred within 120 days before serum sampling were associated with 98% higher levels of sNfL. In addition, sNfL was 7% higher for each step increase in EDSS and 13% higher during the pregnancy and postpartum period, compared with outside of that period.
When the investigators included DMT exposure at sampling time in the model, however, the pregnancy and postpartum period no longer had an effect on sNfL. The sNfL levels were 12% lower among patients exposed to DMT, compared with patients without DMT exposure.
Some DMTs, such as interferon-beta, are relatively safe during pregnancy, but the greater the medication’s efficacy, the more problematic it can be, said Dr. Yaldizi. “There are medications that are given, for example, every 6 months, like ocrelizumab. There are other medications that have to be taken daily. Probably the safest medications are those that are not given so often during pregnancy.”
Future research should examine the escalation therapies (i.e., the newer and more effective DMTs) during pregnancy in patients with MS, he added. “Not only in pregnancy, but also in general, we have to look for ways to measure disease activity in patients who switch therapy, who deescalate therapy.”
Pregnancy may not forestall disease activity
“The results of this study demonstrate that DMT withdrawal in the context of pregnancy can lead to subclinical disease re-emergence, as evidenced by increased sNfL levels in the DMT-free period,” said Vilija G. Jokubaitis, PhD, senior research fellow in the department of neuroscience at Monash University, Melbourne. Dr. Jokubaitis was not involved in the study.
“Interestingly, the median EDSS score in this cohort was quite low, demonstrating that, even in women with mild disease, pregnancy may not be sufficient to protect against ongoing MS activity.” Nevertheless, 28 of the 63 women were exposed to monoclonal antibody therapy, so it is unclear whether these women have mild disease or well-managed disease on DMT, she added.
“This study provides further evidence that pregnancy planning requires advanced planning, and that therapy continuation into pregnancy should be considered, particularly in women with moderate disease activity, to protect against disease reactivation,” said Dr. Jokubaitis.
The strengths of the study include its prospective design, the investigators’ ability to describe the various DMT exposures before and during pregnancy, and the multivariable mixed-effects modeling, she added. On the other hand, the results are at the group level, individual trajectories in sNfL level are not described, and the small sample size prevented the investigators from differentiating between the effects of various DMTs on sNfL outcomes. In addition, Dr. Yaldizli and colleagues did not take time off DMT into account in the models; they considered DMT exposure as a dichotomous variable.
“More work is needed to determine the therapeutic strategies that will give women with MS the greatest protection against disease reactivation in pregnancy and post partum, whilst also protecting fetal and neonatal outcomes,” said Dr. Jokubaitis. Group studies will enable researchers to identify trends, but neurologists ultimately need to provide individualized advice to their patients. “There is a need to look at [the effect of] DMT identity, timing, and duration of DMT withdrawal on fluctuation of sNfL levels, and how these relate to baseline disease severity,” Dr. Jokubaitis added. Furthermore, researchers must compare sNfL changes in pregnancy between patients with MS and healthy women in large cohorts.
The analysis by Dr. Yaldizli and colleagues was conducted without outside funding. The Swiss MS Cohort receives funding from the Swiss MS society, Biogen, Celgene, Sanofi, Merck, Novartis, Roche, and research associations such as the International Progressive MS Alliance and the Swiss National Science Foundation. Dr. Yaldizli received grants from ECTRIMS/MAGNIMS, the University of Basel, Pro Patient Stiftung, University Hospital Basel, Free Academy Basel, and the Swiss MS Society. He has received advisory board fees from Sanofi Genzyme, Biogen, Almirall, and Novartis. Dr. Jokubaitis has received conference travel support from Merck and Roche and speakers honoraria from Biogen and Roche. These relationships are not related to the current study. Dr. Jokubaitis receives research support from the Australian National Health and Medical Research Grant and MS Research Australia.

Cognitive impairments in major depression cluster in three patterns
Objective neuropsychological tests can be used to subclassify the cognitive symptoms present in patients with major depression into three patterns having implications for treatment responsiveness, Gitte Moos Knudsen, MD, reported at the virtual congress of the European College of Neuropsychopharmacology.
“Our data highlight the importance of assessing and targeting cognitive symptoms,” said Dr. Knudsen, the ECNP president and professor of neurology at the University of Copenhagen.
She was a coauthor of the Danish NeuroPharm study, in which 92 antidepressant-free patients with moderate or severe major depressive disorder and 103 healthy controls completed a comprehensive neuropsychological test battery. The testing included a validation study of the EMOTICOM test battery, a novel neuropsychological test battery developed specifically to assess what has been called “hot” cognition, such as emotion processing, social cognition, and affective verbal memory.
Overall, the depressed patients collectively showed moderate increases in measures of guilt and shame, moderate deficits in working and verbal memory, moderately slowed reaction time, and mild to moderate negative affective bias, compared with controls. No correlation was found between performance on any of the individual cognitive domains and depression severity as measured using the Hamilton Depression Rating Scale, underscoring the concept that cognitive impairment is a distinct component of depressive pathology rather than an extension of the classic mood and somatic symptoms of major depression.
Cluster analysis revealed three distinct patterns of cognitive impairment in the study population. Unlike the individual cognitive domains, these cognitive clusters did correlate with depression severity. The implication is that as they become available.
Investigators classified 38 of the 92 patients with major depressive disorder as falling within Cluster A. That is, they exhibited marked deficits in hot cognition expressed in a greatly impaired ability to accurately identify facial emotions on photographs, with resultant high scores for emotion recognition bias and emotion misattribution bias. This impairment in hot cognition was accompanied by minimal guilt and shame and little or no deficits in the cold cognitive domains of verbal and working memory.
Cluster B, composed of 28 patients, was characterized by generally good cognitive function, with positive biases in emotion processing, near-normal guilt and shame ratings, but moderate deficits across the cold cognition domains, making for a mirror image of Cluster A.
The 26 patients in Cluster C demonstrated large deficits in both the hot and cold cognition domains, with particularly pronounced guilt and shame scores.
The three clusters didn’t differ in terms of age or sex. However, patients in Cluster C had significantly more severe core depressive symptoms as measured by Hamilton scores than in Clusters A and B.
This analysis from the NeuroPharm study was cross-sectional. Dr. Knudsen cited a recent large Chinese longitudinal study to underscore how the prevalence of patient-reported cognitive deficits in major depressive disorder is high. And while those deficits decrease over time, they nonetheless remain substantial after 6 months on antidepressant therapy.
That study included 598 Chinese outpatients with major depressive disorder. At baseline, 77% had cognitive symptoms as evidenced by a total score of 21 or more on the self-rated Perceived Deficits Questionnaire–Depression (PDQ-D). One month after going on antidepressant monotherapy, the prevalence of cognitive symptoms had dropped to 59%. At 2 months, the rate was 45%. And at month 6, a PDQ-D score of 21 or greater was still present in 32.4% of patients. High baseline PDQ-D scores were associated with worse clinical outcomes, including a lower treatment response rate at 1 month and a lower remission rate at 2 months. Moreover, high PDQ-D scores at 2 months were associated with lower remission and higher relapse rates at 6 months.
Dr. Knudsen reported having no financial conflicts regarding the NeuroPharm study, which was conducted free of commercial support. She serves as an adviser to Sage Therapeutics and Sanos.

The three clusters didn’t differ in terms of age or sex. However, patients in Cluster C had significantly more severe core depressive symptoms as measured by Hamilton scores than in Clusters A and B.
This analysis from the NeuroPharm study was cross-sectional. Dr. Knudsen cited a recent large Chinese longitudinal study to underscore how the prevalence of patient-reported cognitive deficits in major depressive disorder is high. And while those deficits decrease over time, they nonetheless remain substantial after 6 months on antidepressant therapy.
That study included 598 Chinese outpatients with major depressive disorder. At baseline, 77% had cognitive symptoms as evidenced by a total score of 21 or more on the self-rated Perceived Deficits Questionnaire–Depression (PDQ-D). One month after going on antidepressant monotherapy, the prevalence of cognitive symptoms had dropped to 59%. At 2 months, the rate was 45%. And at month 6, a PDQ-D score of 21 or greater was still present in 32.4% of patients. High baseline PDQ-D scores were associated with worse clinical outcomes, including a lower treatment response rate at 1 month and a lower remission rate at 2 months. Moreover, high PDQ-D scores at 2 months were associated with lower remission and higher relapse rates at 6 months.
Dr. Knudsen reported having no financial conflicts regarding the NeuroPharm study, which was conducted free of commercial support. She serves as an adviser to Sage Therapeutics and Sanos.
Objective neuropsychological tests can be used to subclassify the cognitive symptoms present in patients with major depression into three patterns having implications for treatment responsiveness, Gitte Moos Knudsen, MD, reported at the virtual congress of the European College of Neuropsychopharmacology.
“Our data highlight the importance of assessing and targeting cognitive symptoms,” said Dr. Knudsen, the ECNP president and professor of neurology at the University of Copenhagen.
She was a coauthor of the Danish NeuroPharm study, in which 92 antidepressant-free patients with moderate or severe major depressive disorder and 103 healthy controls completed a comprehensive neuropsychological test battery. The testing included a validation study of the EMOTICOM test battery, a novel neuropsychological test battery developed specifically to assess what has been called “hot” cognition, such as emotion processing, social cognition, and affective verbal memory.
Overall, the depressed patients collectively showed moderate increases in measures of guilt and shame, moderate deficits in working and verbal memory, moderately slowed reaction time, and mild to moderate negative affective bias, compared with controls. No correlation was found between performance on any of the individual cognitive domains and depression severity as measured using the Hamilton Depression Rating Scale, underscoring the concept that cognitive impairment is a distinct component of depressive pathology rather than an extension of the classic mood and somatic symptoms of major depression.
Cluster analysis revealed three distinct patterns of cognitive impairment in the study population. Unlike the individual cognitive domains, these cognitive clusters did correlate with depression severity. The implication is that as they become available.
Investigators classified 38 of the 92 patients with major depressive disorder as falling within Cluster A. That is, they exhibited marked deficits in hot cognition expressed in a greatly impaired ability to accurately identify facial emotions on photographs, with resultant high scores for emotion recognition bias and emotion misattribution bias. This impairment in hot cognition was accompanied by minimal guilt and shame and little or no deficits in the cold cognitive domains of verbal and working memory.
Cluster B, composed of 28 patients, was characterized by generally good cognitive function, with positive biases in emotion processing, near-normal guilt and shame ratings, but moderate deficits across the cold cognition domains, making for a mirror image of Cluster A.
The 26 patients in Cluster C demonstrated large deficits in both the hot and cold cognition domains, with particularly pronounced guilt and shame scores.

Identifying pancreatitis etiology may help prevent progression
Pancreatitis remains the third most common gastroenterological cause of hospital admission, and staying on top of the latest quality indicators is important for the care and safety of patients, said Jamie S. Barkin, MD, professor of medicine in the division of gastroenterology at the University of Miami, in a virtual presentation at the annual Digestive Diseases: New Advances conference jointly provided by Rutgers and Global Academy for Medical Education.
The basics of treatment have changed, said Dr. Barkin. “A large volume of ringers lactate intravenous fluids given within the first 24 hours of admission, as opposed to normal saline, may decrease the inflammatory response in patients with acute pancreatitis.” The preferred diagnostic method remains clinical evaluation along with use of serum lipase, which is more sensitive than serum amylase (97%) but with similar specificity (99%), and current wisdom does not support the need for an early CT for diagnosis unless there is a diagnostic dilemma.
Early establishment of disease etiology and its therapy is imperative to attempt to prevent recurrent episodes and progression to chronic pancreatitis, Dr. Barkin said. Genetic testing studies suggest that approximately 10% of acute pancreatitis cases are the result of genetic factors, and Dr. Barkin recommended performing genetic testing after a first attack of idiopathic acute pancreatitis, especially in younger patients.
There is an extensive list of medications that may cause acute pancreatitis, according to a recent study published in PLOS One, the most common of which include acetaminophen, amiodarone, azathioprine, and angiotensin-converting enzyme inhibitors, Dr. Barkin said. In addition, acute pancreatitis can be caused by isonicotinic acid hydrazide (INH), cannabis, L-asparaginase, metronidazole, mesalamine, simvastatin, sulindac, sitagliptin, thiazides, tigecycline, trans-retinoic acid, and valproic acid, among others.
Current recommendations for hospital treatment of acute pancreatitis include early large volume fluid replacement and initiation of per-oral nutrition as soon as able to be tolerated, as well as pain control, Dr. Barkin said. In addition, management includes strict glycemic and triglyceride control and performance of cholecystectomy for mild and or moderate biliary pancreatitis or endoscopic retrograde cholangiopancreatography (ERCP) if the patient is not an operative candidate during the same hospital stay.
Current recommendations for the prevention of acute pancreatitis include avoidance of irritants such as alcohol, nicotine, and drugs known to cause acute pancreatitis, including marijuana, said Dr. Barkin. In addition, controlling metabolic factors such as obesity, diabetes, and triglycerides can help reduce risk of recurrent episodes in susceptible patients. Several of these factors are also linked to increased risk for progression of acute pancreatitis to chronic pancreatitis.
For patients with biliary pancreatitis, Dr. Barkin noted that cholecystectomy should be performed prior to discharge during the index hospitalization. “In patients who cannot undergo surgery, endoscopic sphincterotomy should be performed to allow spontaneous passage of any stones still in the gallbladder,” he noted.
In addition, patients who have experienced an attack of acute pancreatitis should be screened long-term for development of pancreatic exocrine insufficiency, which may be present in approximately one-quarter of patients following an acute pancreatitis episode, and diabetes, Dr. Barkin said. He cited a population-based study published in the American Journal of Gastroenterology in 2019 in which individuals with postpancreatitis diabetes had significantly higher rates of all-cause mortality, as well as hospitalization for conditions including chronic pulmonary disease, severe renal disease, and infectious disease.
Finally, at the time of discharge, it is essential to evaluate acute pancreatitis patients for risk of readmission, Dr. Barkin said. In addition to severe disease and systemic inflammatory response syndrome at the time of patient discharge, several factors increase the likelihood of readmission including ongoing abdominal pain requiring use of pain medicine, obesity, and inability to tolerate solid food, he noted.

FROM DIGESTIVE DISEASES: NEW ADVANCES
Neoadjuvant mFOLFIRINOX improves DFS, OS effect uncertain
Adding neoadjuvant chemotherapy to standard treatment of locally advanced rectal cancer more than doubled the pathologic complete response rate and significantly improved 3-year disease-free survival (DFS) in a multicenter, phase 3 trial.
The pathologic complete response rate was 12.1% in the standard therapy arm and 27.8% with the addition of neoadjuvant chemotherapy – modified FOLFIRINOX (oxaliplatin, irinotecan, folinic acid, and 5-fluorouracil). The 3-year DFS rates were 68.5% and 75.7%, respectively.
It’s not clear if the response and DFS benefits of modified FOLFIRINOX will translate to improved overall survival (OS). Nevertheless, neoadjuvant therapy with modified FOLFIRINOX “should now be considered as a new option” for T3-T4 rectal cancer, said investigator Christophe Borg, MD, PhD, of the University of Besancon (France).
Dr. Borg presented this research at the European Society for Medical Oncology Virtual Congress 2020.
Study discussant David Sebag-Montefiore, MBBS, of the University of Leeds (England), was more cautious about these findings. Although the results were “clear” in this trial, “we have not seen any overall survival data,” Dr. Sebag-Montefiore stressed.
Study details
In explaining the trial, dubbed PRODIGE 23, Dr. Borg noted that local recurrence is minimal with modern standard treatment – chemoradiation followed by total mesorectal excision (TME) – but distant metastases occur in up to 30% of patients and remain a significant problem despite years of research. Adjuvant chemotherapy after surgery might help, but it “is still not proven” to reduce the risk, so compliance is poor, Dr. Borg said.
He and his colleagues conducted the PRODIGE 23 trial to see if neoadjuvant chemotherapy could reduce the risk of metastases.
The study enrolled 461 patients, 18-75 years old, with cT3-4 rectal cancer. Patients were randomized to receive:
- Standard therapy, consisting of chemoradiation (50.4 gy/5 weeks plus capecitabine), followed 7 weeks later by TME, then 6 months of adjuvant chemotherapy with FOLFOX (folinic acid, fluorouracil, and oxaliplatin) or XELOX (capecitabine and oxaliplatin, also known as CAPOX).
- Six cycles of modified FOLFIRINOX, followed by chemoradiation (50.4 gy/5 weeks plus capecitabine), TME, and FOLFOX/XELOX adjuvant therapy for 3 months instead of 6 months.
Overall, 119 patients in the standard therapy arm and 130 in the neoadjuvant arm completed their assigned protocol.
Results
The median follow-up was 46.5 months. The 3-year DFS, the primary endpoint, was significantly higher in the neoadjuvant arm than in the standard therapy arm (75.7% vs. 68.5%; hazard ratio = 0.69; P = .034). This correlated with a significant improvement in 3-year metastasis-free survival (78.8% vs. 71.7%; HR = 0.64; P < .02).
The rate of palliative surgery was significantly higher in the standard therapy arm (3.7% vs. 0%; P = .007), but there were no significant differences in other surgical outcomes.
A difference in 60-day postoperative mortality favored neoadjuvant therapy (0% vs. 2.8%, P = .03).
Grade 3 or 4 adverse events during adjuvant therapy were less common when subjects had neoadjuvant chemotherapy (44.4% vs. 74.1%, P < .001).
Quality of life outcomes were similar between the treatment arms, except that men in the neoadjuvant arm were significantly less likely to suffer from impotence (P = .03).
Dr. Sebag-Montefiore said these findings are “very important,” but PRODIGE 23 is not “a practice-defining or practice-changing study,” especially without OS data.
He noted that the RAPIDO trial had similar outcomes with a different neoadjuvant regimen.
RAPIDO had a standard treatment arm with capecitabine-based chemoradiotherapy followed by TME and optional CAPOX/FOLFOX, and the experimental arm consisted of short-course radiotherapy followed by CAPOX/FOLFOX then TME. The experimental arm had superior 3-year disease-related treatment failure (30.4% vs. 23.7%, P = .019) but no better OS (89.1% vs. 88.8%, P = .59).
PRODIGE 23 was funded by the French National Cancer Institute and the French National League Against Cancer. Dr. Borg disclosed relationships with Roche, Servier, Pierre Fabre, and Merck Sharp & Dohme. Dr. Sebag-Montefiore didn’t have any disclosures.

Dr. Brian Mandell gives his take on ACR’s newest gout guideline
Guidance on the initiation and use of urate-lowering therapies was among the strong recommendations in the updated gout guideline recently issued by the American College of Rheumatology, said Brian F. Mandell, MD, PhD, in a virtual presentation at the annual Perspectives in Rheumatic Diseases held by Global Academy for Medical Education.
The 2020 American College of Rheumatology Guideline for the Management of Gout is “intended to provide guidance for particular patterns of practice and not to dictate the care of a particular patient,” said Dr. Mandell, chair of academic medicine at the Cleveland Clinic in Ohio and cochair of the conference. However, “there was a hope that, with additional evidence since the previous guideline issued in 2012, the recommendations are more firmly based and will improve care,” he said.
Of 42 recommendations, 16 were strong, and these included guidance on several points: when to initiate urate-lowering therapy and using a treat-to-target strategy for lowering serum uric acid to less than 6 mg/dL; prophylaxis against attacks; the use of allopurinol as the first-choice drug and how to avoid hypersensitivity reactions; the use of pegloticase (Krystexxa); and treating flares.
Hyperuricemia does not automatically equal gout, Dr. Mandell said. A 2018 published analysis of data from several large cohorts including 18,889 adults who were gout-free at baseline showed that serum uric acid levels could not accurately predict an initial gout attack. Therefore, the guideline conditionally recommends against initiating any pharmacologic urate-lowering therapy in patients with asymptomatic hyperuricemia. The guideline authors intentionally did not include the presence of comorbidities or deposits of uric acid in making their recommendation. But when advising an individual patient, these factors plus the patient’s age and family history should be considered, he said. “Individualize the decision to use ULT [urate-lowering therapy] to prevent possible future flares,” he advised, with consideration of age, the effects of the flare on the patient’s life, and challenges in treating flares.
For patients who are being treated with urate-lowering therapy, a published study indicated that if treatment is discontinued, “gout attacks will recur, depending on the new serum urate level,” Dr. Mandell said. “Maintenance of low SUA [serum uric acid] must be lifelong to stop attacks,” he emphasized, noting that this is counter to a management guideline published by the American College of Physicians in 2017.
“For patients starting any ULT, we strongly recommend allopurinol over all other urate-lowering therapies as the preferred first-line agent for all patients, including those with CKD [chronic kidney disease] stage 3 or higher,” according to the new guideline, which also recommends starting at a low dose followed by dose titration to target versus starting at a higher dose.
Two reasons in support of a slow up-titration of urate-lowering therapy are a lower frequency of mobilization flares and a possibly lower chance of allopurinol hypersensitivity reactions, Dr. Mandell said.
Although the guideline recommends allopurinol over probenecid, “probenecid works well as monotherapy and effectively as add-on therapy to a xanthine oxidase inhibitor, and it is cheap,” Dr. Mandell said.
Allopurinol can be associated with life-threatening hypersensitivity reactions, but most of these have been associated with a higher-than-recommended starting dose, according to the literature, he noted. The new guideline suggests checking for the HLA-B*5801 haplotype in high-risk demographic groups, and if it is present, to use an alternative to allopurinol if possible
The updated guideline also carries a strong recommendation for the use of pegloticase for patients with frequent gout flares and nonresolving subcutaneous tophi, but it strongly recommends against switching to pegloticase for patients with infrequent gout flares and no tophi.
However, Dr. Mandell said that he will consider off-label treatment of gout with pegloticase “in patients where a shorter time to response really matters,” which is consistent with his belief that, within these treatment principles, the management of gout must be individualized to the specific patient.
For treating acute gout flares, the guideline recommendations strongly supports the use of oral colchicine, NSAIDs, or glucocorticoids as an appropriate first-line therapy, based on patient factors and preferences, instead of using interleukin-1 inhibitors or adrenocorticotropic hormone. However, the interleukin-1 inhibitor anakinra has shown relatively rapid and successful response in treating patients hospitalized with acute gout, Dr. Mandell said. No large, randomized, trials have been conducted, but he cited his experience at the Cleveland Clinic in Ohio, where anakinra is the most common treatment for acute gout on inpatient consults, and he cited a representative small study of 26 patients in which 73% showed “significant response” within 5 days of treatment, which meant that they were able to move and bear weight without pain. In addition, a more recent study of 100 hospitalized patients in the Journal of Rheumatology, found that 75% showed a rapid response to anakinra and improvement or resolution of flares within 4 days, Dr. Mandell said.
Dr. Mandell disclosed relationships with companies including Horizon, Ardea/AstraZeneca/Ironwood, and Takeda. He served as coauthor on the 2012 American College of Rheumatology gout guideline.

Guidance on the initiation and use of urate-lowering therapies was among the strong recommendations in the updated gout guideline recently issued by the American College of Rheumatology, said Brian F. Mandell, MD, PhD, in a virtual presentation at the annual Perspectives in Rheumatic Diseases held by Global Academy for Medical Education.
The 2020 American College of Rheumatology Guideline for the Management of Gout is “intended to provide guidance for particular patterns of practice and not to dictate the care of a particular patient,” said Dr. Mandell, chair of academic medicine at the Cleveland Clinic in Ohio and cochair of the conference. However, “there was a hope that, with additional evidence since the previous guideline issued in 2012, the recommendations are more firmly based and will improve care,” he said.
Of 42 recommendations, 16 were strong, and these included guidance on several points: when to initiate urate-lowering therapy and using a treat-to-target strategy for lowering serum uric acid to less than 6 mg/dL; prophylaxis against attacks; the use of allopurinol as the first-choice drug and how to avoid hypersensitivity reactions; the use of pegloticase (Krystexxa); and treating flares.
Hyperuricemia does not automatically equal gout, Dr. Mandell said. A 2018 published analysis of data from several large cohorts including 18,889 adults who were gout-free at baseline showed that serum uric acid levels could not accurately predict an initial gout attack. Therefore, the guideline conditionally recommends against initiating any pharmacologic urate-lowering therapy in patients with asymptomatic hyperuricemia. The guideline authors intentionally did not include the presence of comorbidities or deposits of uric acid in making their recommendation. But when advising an individual patient, these factors plus the patient’s age and family history should be considered, he said. “Individualize the decision to use ULT [urate-lowering therapy] to prevent possible future flares,” he advised, with consideration of age, the effects of the flare on the patient’s life, and challenges in treating flares.

Divergent findings with paclitaxel and nab-paclitaxel in TNBC
The trials, IMpassion130 and IMpassion131, both enrolled patients with metastatic or unresectable, locally advanced TNBC.
In IMpassion131, adding atezolizumab to paclitaxel did not improve progression-free survival (PFS) or overall survival (OS), regardless of programmed death–ligand 1 (PD-L1) expression.
In IMpassion130, adding atezolizumab to nab-paclitaxel did not improve OS in the intention-to-treat (ITT) population but did provide a “clinically meaningful” improvement in OS among PD-L1-positive patients, according to investigators.
IMpassion130 and IMpassion131 were presented during the same session at the European Society for Medical Oncology (ESMO) Virtual Congress 2020.
Potential reasons for the different outcomes in the two studies require further exploration, according to David Miles, MD, of Mount Vernon Cancer Centre in Northwood, England, who presented the findings from IMpassion131.
ESMO discussant Lisa A. Carey, MD, of the University of North Carolina at Chapel Hill, posited three possible explanations for the divergent findings. The steroids necessary with paclitaxel dosing may have had a negative effect on immune checkpoint inhibitor activity, differences in study populations may have played a role, or the divergent findings could be caused by chance.
Steroid use in IMpassion131 could have played a negative role because of its lympholytic activity, but other indications with steroid use have not demonstrated attenuated benefits, said Leisha A. Emens, MD, PhD, of the University of Pittsburgh Medical Center, who presented the findings from IMpassion130 at ESMO 2020.
“If I were a patient, based on the data to date, I would want nab-paclitaxel with atezolizumab,” Dr. Emens said.
Trial details
Both trials are phase 3, double-blind, placebo-controlled studies of women with metastatic or unresectable locally advanced TNBC who had received no prior therapy for advanced TNBC.
IMpassion130 included 451 patients randomized to atezolizumab plus nab-paclitaxel and 451 randomized to placebo plus nab-paclitaxel. Patients received nab-paclitaxel at a starting dose of 100 mg/m2 via IV infusion on days 1, 8, and 15 of each 28-day cycle for at least six cycles.
In both studies, patients received atezolizumab at 840 mg on days 1 and 15 of a 28-day cycle in their active treatment arms.
IMpassion131 included 651 patients randomized 2:1 to atezolizumab plus paclitaxel (n = 431) or placebo plus paclitaxel (n = 220). Patients received paclitaxel at 90 mg/m2 on days 1, 8, and 15 every 28 days until disease progression or unacceptable toxicity.
Baseline characteristics were well balanced between the treatment arms in both studies. Less than half of patients – 45% in IMpassion131 and 41% in IMpassion130 – were PD-L1 positive.
Results of IMpassion131
The primary endpoint in IMpassion131 was PFS, and there was no significant difference in PFS between the treatment arms.
“The primary objective of IMpassion131 was not met,” Dr. Miles said. “[The] addition of atezolizumab to paclitaxel did not significantly improve PFS in patients with PD-L1-positive metastatic triple-negative breast cancer.”
In the PD-L1-positive population, the median PFS was 5.7 months in the placebo arm and 6.0 months in the atezolizumab arm (stratified hazard ratio, 0.82, P = .20).
In the ITT population, the median PFS was 5.6 months in the control arm and 5.7 months in the atezolizumab arm (HR, 0.86).
In subgroup analyses, Dr. Miles noted, “There was no clue about adverse or beneficial effects in any subgroup.”
The updated OS analysis demonstrated no benefit with atezolizumab in the ITT population or the PD-L1-positive population. In fact, there was a trend toward better OS for the control group in the latter analysis.
In the PD-L1-positive population, the median OS was 28.3 months in the control arm and 22.1 months in the atezolizumab arm (HR, 1.12). The 2-year OS rates were 51% and 49%, respectively.
In the ITT population, the median OS was 22.8 months in the control arm and 19.2 months in the atezolizumab arm (HR, 1.11). The 2-year OS rates were 45% and 42%, respectively.
The safety profile of the atezolizumab-paclitaxel combination was consistent with known side effects of the individual drugs, Dr. Miles said. There were four fatal treatment-related adverse events in the atezolizumab arm.
Results of IMpassion130
Presenting the final OS analysis from IMpassion130, Dr. Emens noted that the study’s findings have led to recommendations for atezolizumab plus nab-paclitaxel as first-line treatment of PD-L1-positive TNBC in international guidelines.
The median OS in the ITT population was 18.7 months in the placebo arm and 21.0 months in the atezolizumab arm (stratified HR, 0.87, P = .077). The 3-year OS rates were 25% and 28%, respectively.
The median OS in the PD-L1-positive population was 17.9 months in the placebo arm and 25.4 months in the atezolizumab arm (HR, 0.67). The 3-year OS rates were 22% and 36%, respectively.
A P value is not available for the between-arm OS comparison in the PD-L1-positive population. OS was not formally tested in this group because the OS boundary for statistical significance was not crossed in the ITT population. However, Dr. Emens said there was a “clinically meaningful” OS benefit observed with atezolizumab in the PD-L1-positive patients.
Treatment withdrawals caused by adverse events were more common in the atezolizumab arm (19% vs. 8%). The most common of these was neuropathy, Dr. Emens said. However, she noted that atezolizumab-related adverse events were generally low grade and easily managed.
“These results support a positive benefit-risk profile for atezolizumab plus nab-paclitaxel as first-line therapy in patients with PD-L1-positive metastatic triple-negative breast cancer,” Dr. Emens concluded.
Both studies were funded by F. Hoffman–La Roche. Dr. Miles, Dr. Emens, and Dr. Carey disclosed financial relationships with Roche and other companies.

Both studies were funded by F. Hoffman–La Roche. Dr. Miles, Dr. Emens, and Dr. Carey disclosed financial relationships with Roche and other companies.

Higher glycemic time in range may benefit T2D patients
Patients with type 2 or type 1 diabetes who stay in a blood glucose range of 70-180 mg/dL at least 70% of the time have the lowest rates of major adverse coronary events, severe hypoglycemic episodes, and microvascular events, according to a post hoc analysis of data collected from 5,774 patients with type 2 diabetes.
Data collected by the DEVOTE trial showed that every additional 10% of the time that a patient with type 2 diabetes (T2D) spent in their target range for blood glucose linked with a significant 6% reduced rate for developing a major adverse cardiovascular event (MACE), Richard M. Bergenstal, MD, said at the virtual annual meeting of the European Association for the Study of Diabetes.
For every 10% increase in time in range (TIR), patients showed an average 10% drop in their incidence of severe hypoglycemic episodes.
Increasing evidence from post hoc analyses
These findings confirmed a prior post hoc analysis of data collected in the DCCT trial (NCT00360815), which were published in the New England Journal of Medicine, although those results showed significant relationships between increased TIR and decreased rates of retinopathy and microalbuminuria. For every 10% drop in TIR, retinopathy rose by 64% and microalbuminuria increased by 40%, according to a post hoc analysis of the DCCT data that Dr. Bergenstal helped run and was published in Diabetes Care.
“It’s becoming clear that time in range is an important metric for diabetes management, and our new findings and those previously reported with the DCCT data make it look like time in range is becoming a good marker for clinical outcomes as well,” said Dr. Bergenstal, an endocrinologist at the Park Nicollet Clinic in Minneapolis.
“It’s a new concept, getting time-in-range data,” said Dr. Bergenstal, who was a coauthor of recommendations from Diabetes Care that were made in 2019 by an expert panel organized by the Advanced Technologies & Treatments for Diabetes Congress. “We think this will be a good marker to keep glycemia in a safe range, and the results look positive.” Patients who stay in the blood glucose range of 70-180 mg/dL (3.9-10.0 mmol/L) at least 70% of the time generally have an hemoglobin A1c of about 7%, which is what makes it a good target for patients and clinicians to focus on. Patients with a 50% TIR rate generally have an HbA1c of about 8%.
But a TIR assessment can be more informative than HbA1c, said the 2019 recommendations document. It called TIR assessments “appropriate and useful as clinical targets and outcome measurements that complement A1c for a wide range of people with diabetes.”
Data mining from DEVOTE
The analysis run by Dr. Bergenstal and his associates used data from 5,774 of the 7,637 patients enrolled in the DEVOTE trial, for whom adequate longitudinal blood glucose data were available to derive and track TIR. DEVOTE had the primary aim of comparing two different types of insulin in patients with T2D, according to its explanation in the New England Journal of Medicine. The DEVOTE patients did not undergo routine continuous blood glucose monitoring, so derivation of TIR was the only option with the dataset, Dr. Bergenstal said. “We’re trying to get continuous blood monitoring into T2D trials,” he said.
The post hoc analysis showed that, during the study’s follow-up of just under 2 years, patients who maintained a derived TIR of 70%-100% had about a 6% MACE rate, which peaked at nearly twice that in patients whose TIR was 30% or less. The analysis showed a roughly positive linear relationship between TIR and MACE rates across the range of TIR values. In an adjusted analysis, patients with at least a 70% TIR had a significant 31% lower rate of MACE events, compared with patients whose TIR was 50% or less.
A second analysis that looked for the association between TIR and incidence of hypoglycemic episodes showed a somewhat similar positive relationship, with incidence rates of severe hypoglycemia episodes of about 4%-5% among patients with a TIR of 70% or greater, and a rate of about 7% in patients with a TIR of 30% or less, spiking to 14% among patients with a TIR of 10% or less. In an adjusted analysis, patients with a TIR of at least 70% had a significant 46% lower rate of severe hypoglycemic events, compared with patients whose TIR was 50% or less. This finding belies a common misconception that the tighter glycemic control that produces a higher TIR will lead to increased episodes of severe hypoglycemia, Dr. Bergenstal noted.
He also reported less extensive data on microvascular events. In an adjusted analysis, patients with a TIR of at least 70% had a significant 40% cut in these events compared with patients with 50% or less TIR.
DEVOTE was funded by Novo Nordisk. Dr. Bergenstal has had financial relationships with Novo Nordisk and several other companies.

Exercise cuts diabetes death risk by a third in two studies
Type 2 diabetes patients could lower their risk for death from any cause by up to a third by exercising at a moderate to high level or by cycling, according to data from two studies reported at the virtual annual meeting of the European Association for the Study of Diabetes.
Yun-Ju Lai, MD, and colleagues from the Puli branch of Taichung Veterans General Hospital in Nantou, Taiwan, found that persons with type 2 diabetes who exercised at moderate to high intensity had a 25%-32% decreased risk for death, compared with those who did not exercise.
In a separate study, Mathias Ried-Larsen, MSc, PhD, group leader at the Centre for Physical Activity Research, Rigshospitalet, Copenhagen, and associates found that cycling was associated with a 25%-31% decreased risk for all-cause death compared to no cycling, and that cycling also reduced cardiovascular mortality.
Results fit with ADA recommendations
“There is really nothing surprising about these results as others have shown that regular participation in physical activity lowers both overall mortality rates and morbidity,” commented Sheri Colberg-Ochs, PhD, professor emerita in exercise science at Old Dominion University in Norfolk, Va., in an interview.
“Regular exercise participation lowers the risk of mortality in almost all populations with many different health conditions. It is not specific to people with type 2 diabetes,” Dr. Colberg-Ochs said. “These data add further support to the ADA [American Diabetes Association] recommendations by again suggesting that being more active leads to many health benefits for people with type 2 diabetes.”
Dr. Colberg-Ochs, who was not involved in either study, is recognized by the ADA as an Outstanding Educator in Diabetes. She was also involved in writing the ADA’s position statement on physical activity/exercise in diabetes, which advocate that adults with type 2 diabetes should reduce sedentary time and undertake both aerobic and resistance exercise training to help optimize their glycemic and general health outcomes.
Asian population understudied
In an interview Dr. Lai acknowledged that epidemiologic studies had shown that exercise reduced the risk of cardiovascular events and mortality in subjects with type 2 diabetes. “However, the dose of exercise capacity for reducing mortality risk in people with type 2 diabetes was not yet well investigated, especially in the Asian population.”
Dr. Lai and colleagues analyzed data on 4,859 subjects drawn from two Taiwanese databases – the National Health Interview Survey and the National Health Insurance research database – to study what effect exercise “capacity” had on the risk for death in those with type 2 diabetes.
“Information about physical activity during leisure time was collected by asking the questions: ‘How often do you exercise every week? What kind of exercise do you do? How long do you do the exercise?’, Dr. Lai said. “We included nearly all kinds of exercise in the analysis, such as jogging, swimming, walking, dancing, riding, and so on.”
Each exercise had an activity intensity code expressed as kilocalories per minute. This was used to determine the exercise “capacity” by multiplying it by how frequently the exercise was performed per week and for how long each time.
“I don’t think ‘capacity’ is the right word to use here. The equation they used describes their exercise ‘volume,’ not their capacity. Self-reported exercise is notoriously inaccurate,” Dr. Colberg-Ochs observed. Furthermore, “just asking people how much they exercise and at what intensity [without using a validated exercise questionnaire] gives questionable results.”
The study’s findings, however, were clear: Those who exercised at a higher level had a significantly decreased risk for all-cause mortality than did those with no exercise habits. The hazard ratio for death by any cause was 0.75 for those who undertook a moderate level of exercise, burning 0-800 kcal per week. Exercising at a higher level burned more than 800 kcal had a HR of 0.68. A significant (P < .01) trend in favor of more exercise was noted.
Cycling reduces all-cause and cardiovascular mortality
In their prospective cohort study, Dr. Ried-Larsen and associates took a more specific look at the effects of exercise on mortality in diabetes by studying a single exercise: cycling. They sampled data on more than 5,000 people collected as part of the European Prospective Investigation into Cancer and Nutrition study. First, they identified participants with diabetes – although they couldn’t distinguish type 1 from type 2 forms because this was self-reported or obtained from registries. They then identified those who reported cycling at their baseline assessment and those who reported a change in cycling habits at their second examination around 5 years later.
At baseline, 38% of participants reported that they cycled every week. The mean age was 56 years, diabetes duration was 8 years, one-fifth were smokers, and the average body mass index was 29 kg/m2.
Participants who reported cycling up to 1 hour every week at baseline had a 25% reduction in all-cause mortality, compared with those who did not cycle. The biggest reduction (31%) in all-cause mortality was seen for cycling 2.5-5 hours a week; cycling for 1-2.5 hours, and for more than 5 hours, yielded 23% and 24% risk reductions, respectively.
A reverse J–shaped relationship between cycling duration and reduction in all-cause mortality was seen, Dr. Ried-Larsen noted during a live oral session at the virtual meeting. “The maximum benefit [was at] around 5 hours per week, and the benefits persisted until around 9 hours per week.” Adjustment for the prevalence of stroke, MI, cancer, hyperlipidemia, hypertension, and central obesity did not alter the findings.
“The direction of the association was the same for cardiovascular mortality as all-cause mortality, although a bit weaker, with the maximum benefit being around 4 hours per week, and that persisted up until around 8 hours per week,” Dr. Ried-Larsen said.
The benefits of cycling on all-cause and cardiovascular mortality were lost, however, if those who cycled at baseline stopped by the second examination. Those who did not cycle at the first but did at the second examination got a benefit on both, as did those who continued cycling.
“Cycling is among one of the preferred activities for diabetes patients, so it actually may help them to achieve the recommend level of physical activity,” Dr. Ried-Larsen said.
Tailored exercise program important
Advice for exercise “should be tailored to the individual and based on starting fitness levels and activity levels,” Dr. Colberg-Ochs recommended.
“Those who are the most sedentary and the least fit have the most to gain from doing any activity. They should be advised to start out slowly and progress slowly with both aerobic activities and some resistance training,” Dr. Colberg-Ochs said.
She added: “In addition, individuals over 40 should engage in regular balance training, and all individuals should do some flexibility exercises.”
The studies received no commercial funding and all those mentioned in this article had no conflicts of interest to disclose.

A reverse J–shaped relationship between cycling duration and reduction in all-cause mortality was seen, Dr. Ried-Larsen noted during a live oral session at the virtual meeting. “The maximum benefit [was at] around 5 hours per week, and the benefits persisted until around 9 hours per week.” Adjustment for the prevalence of stroke, MI, cancer, hyperlipidemia, hypertension, and central obesity did not alter the findings.
“The direction of the association was the same for cardiovascular mortality as all-cause mortality, although a bit weaker, with the maximum benefit being around 4 hours per week, and that persisted up until around 8 hours per week,” Dr. Ried-Larsen said.
The benefits of cycling on all-cause and cardiovascular mortality were lost, however, if those who cycled at baseline stopped by the second examination. Those who did not cycle at the first but did at the second examination got a benefit on both, as did those who continued cycling.
“Cycling is among one of the preferred activities for diabetes patients, so it actually may help them to achieve the recommend level of physical activity,” Dr. Ried-Larsen said.
Tailored exercise program important
Advice for exercise “should be tailored to the individual and based on starting fitness levels and activity levels,” Dr. Colberg-Ochs recommended.
“Those who are the most sedentary and the least fit have the most to gain from doing any activity. They should be advised to start out slowly and progress slowly with both aerobic activities and some resistance training,” Dr. Colberg-Ochs said.
She added: “In addition, individuals over 40 should engage in regular balance training, and all individuals should do some flexibility exercises.”

Identify the dominant symptom in IBS
Many factors can prompt individuals with irritable bowel syndrome (IBS) to seek consultation with a specialist said Anthony Lembo, MD, of Harvard Medical School and Beth Israel Deaconess Medical Center, Boston, in a virtual presentation at the conference jointly provided by Rutgers and Global Academy for Medical Education.
Most patients with IBS suffer with symptoms for years before seeking care, he said.
Common reasons to cause an individual with IBS to seek care include severity of abdominal pain, psychological disturbance such as anxiety, and concerns about organic disease such as colon cancer, perhaps because they know someone who was recently diagnosed with it,” he said.
Our understanding of the pathophysiology of IBS has expanded dramatically over the past decade, Dr. Lembo said. IBS was once thought to be primarily a motility disorder, but currently the many interacting factors include not only motility but also diet, gut microflora, visceral hypersensitivity, immune dysregulation, and brain-gut interactions, he said.
The pathophysiology of postinfectious IBS has been particularly well described and includes the role of anti-CdtB and antivinculin antibodies, and low-grade inflammation in the lining of the intestines, Dr. Lembo explained.
These cases of postinfection IBS can linger for up to a year in approximately 10% of patients, he said.
IBS can affect anyone, anywhere, but it tends to be more common in younger individuals than older adults, and more common in women than men, Dr. Lembo said.
When diagnosing IBS in the clinic setting, a history should include a timeline and triggers for symptoms, he advised. A detailed dietary history, review of medications, and an assessment for alarm features (such as family history of colon cancer or celiac disease, weight loss, anemia, blood in stools, nocturnal awakening, or an onset of symptoms at age older than 50 years) should also be included he said.
Physical signs of systemic and local disease, and a digital rectal exam to assess patients for dyssynergia, especially those with constipation should also be performed, Dr. Lembo added.
In some cases, consider a colonoscopy for patients with IBS, namely those with alarm features, age-appropriate screening criteria, the presence of persistent and frequent watery diarrhea, or in patients who don’t respond to therapy, he added.
Treatment strategies for IBS should start with diet and lifestyle modifications when appropriate, Dr. Lembo said. Encourage patients to pursue moderate to vigorous exercise or some physical activity 3-5 times a week, to get enough sleep, and to start with a traditional IBS diet. Such a diet involves three meals a day, with three or fewer snacks, and not overeating at any of these times, he said. Other diet tips include reducing consumption of fatty or spicy foods, as well as coffee, alcohol, onions, beans, and cabbage. He also advised encouraging patients to avoid gum and soft drinks, as well as artificial sweeteners, and to use soluble rather than insoluble fiber. The low-FODMAP (fermentable oligo-, di-, monosaccharides and polyols) diet has shown benefit in some patients. For those who respond to the low-FODMAP diet it is important to reintroduce foods into their diet. Nutrition consultation should be considered for most patients.
Follow a stepwise approach to treatment, Dr. Lembo emphasized that, if IBS patients with constipation are not improving with diet and lifestyle, over-the-counter medications such as polyethylene glycol can be considered to improve bowel consistency, although the drug’s effect on pain is limited. Prescription options include secretogogues (linaclotide, plenecatide, lubiprostone), and prokinetics (tegaserod, a 5-HT4 partial agonist that was recently reapproved by the FDA for women < 65 years without cardiovascular risk factors). In general, prescription drugs for IBS-C have similar efficacy in most endpoints though differences in their mechanisms of action and side effects should be considered when prescribing a particular agent, he said.
Other perspectives on managing IBS include cognitive behavior therapy and fecal microbiota transplant, Dr. Lembo said. Cognitive behavior therapy improves IBS symptoms after 12 weeks in patients who had weekly sessions compared with controls who received 4 weeks of basic patient education, he noted. As for fecal microbiota transplant, the jury is still out and it is important to note that FMT is not currently approved for clinical practice for patients with IBS, he noted.
Dr. Lembo disclosed relationships with Allergan, Ardelyx, Bayer, Bioamerica, Ironwood, Mylan and Takeda.
