It’s time to introduce a new paradigm for comprehensive care of women’s physical and mental health in the 3 months after giving birth, according to the American College of Obstetricians and Gynecologists.

In their newly revised committee opinion on postpartum care, ACOG encouraged doctors to think of a woman’s immediate postpartum period as a “fourth trimester” during which better care for women may help reduce maternal deaths and morbidity. That care includes a 3-week postpartum visit and a more comprehensive one within 3 months post partum.

Dr. Alison Stuebe
“In addition to being a time of joy and excitement, this ‘fourth trimester’ can present considerable challenges for women, including lack of sleep, fatigue, pain, breastfeeding difficulties, stress, new onset or exacerbation of mental health disorders, lack of sexual desire, and urinary incontinence,” wrote Alison Stuebe, MD, MSc, an associate professor of maternal-fetal medicine at the University of North Carolina in Chapel Hill, and fellow ACOG members who authored the updated committee opinion. “Changes in the scope of postpartum care should be facilitated by reimbursement policies that support postpartum care as an ongoing process, rather than [as] an isolated visit,” they wrote.

Despite common practices in many other cultures that provide intense, dedicated support to women during the 30-40 days after giving birth, U.S. women typically only see their ob.gyn. at a single 6-week postpartum visit and receive little to no other formal maternal support. Beyond that visit, U.S. postpartum care typically is fragmented and inconsistent, split sporadically among pediatric and maternal providers and with little support in the transition from inpatient to outpatient care, the committee wrote.

Further, 40% of women do not attend a postpartum visit at all, and more than half of maternal deaths occur after the baby’s birth. The committee aims to overhaul maternal care and potentially help reduce those numbers. That process begins with prenatal discussions about the mother’s transition to parenthood, caring for herself and her health, her reproductive life plans, her desires related to future children, the timing of future pregnancies, and appropriate contraceptive options and decisions.

“Underutilization of postpartum care impedes management of chronic health conditions and access to effective contraception, which increases the risk of short interval pregnancy and preterm birth,” the committee wrote. “Attendance rates are lower among populations with limited resources, which contributes to health disparities.”

 

 

Components of comprehensive postpartum care

ACOG recommends the prenatal preparation for the postpartum period include discussions about infant feeding, “baby blues,” postpartum emotional health, parenting challenges, postpartum recovery from birth, long-term management of chronic health conditions, choosing a primary care provider for the mother’s ongoing care, her reproductive desires and choices, and any concerns about interpersonal or partner violence.

Before giving birth, a woman should develop a postpartum care plan with her physician and assemble a care team that includes her primary care providers along with family and friends who can provide support. The plan should include contact information for questions and written instructions about postpartum visits and follow-up care.

Prenatal planning also provides an opportunity to discuss a woman’s breastfeeding plans, goals, and questions as well as common physical problems that women may experience in the weeks after giving birth, such as heavy bleeding, pain, physical exhaustion, and urinary incontinence.

Physicians should inform women of the risks and benefits of becoming pregnant within 18 months and advise them not to have pregnancy intervals of less than 6 months. They should also ensure women know all their contraceptive options and should provide any information necessary for women to determine which methods best meet her needs.

The committee recommended a postpartum visit within the first 3 weeks after birth, instead of the current “6-week check,” that is timed and tailored to each woman’s particular needs. This visit allows assessment of postpartum depression risk and/or treatment and discussion of breastfeeding goals and/or difficulties. Approximately one in five women who stopped breastfeeding earlier than they wanted to had ceased within first 6 weeks post partum.

Woman-centered follow-up should be tailored to women’s individual needs and include a comprehensive postpartum visit no later than 12 weeks after giving birth. The comprehensive visit should include a complete assessment of the woman’s physical, social, and psychological well-being, including discussion of “mood and emotional well-being, infant care and feeding, sexuality, contraception, birth spacing, sleep and fatigue, physical recovery from birth, chronic disease management, and health maintenance,” the committee wrote.

The comprehensive visit should include the following components:

  • Postpartum depression and anxiety screening.
  • Screening for tobacco use and substance use.
  • Follow-up on preexisting mental and physical health conditions.
  • Assessment of mother’s confidence and comfort with newborn care, including feeding method, childcare strategy, identification of the child’s medical home, and recommended immunizations for all caregivers.
  • Comfort and confidence with breastfeeding and management of any challenges, such as breastfeeding-associated pain; logistics and legal rights after returning to work or school; and fertility and contraception with breastfeeding.
  • Assessment of material needs, including housing, utilities, food, and diapers.
  • Guidance on sexuality, dyspareunia, reproductive life plans, contraception, and management of recurrent pregnancy complications, such as daily low-dose aspirin to reduce preeclampsia risk and 17a-hydroxyprogesterone caproate to reduce recurrent preterm birth.
  • Sleep, fatigue, and coping options.
  • Physical recovery from birth, including assessment of urinary and fecal continence and guidance on physical activity and a healthy weight.
  • Chronic disease management and long-term implications of those conditions.
  • Health maintenance, including review of vaccination history, needed vaccinations, and well-woman screenings, including Pap test and pelvic examination as indicated.
 

 

“However timed, the comprehensive postpartum visit is a medical appointment; it is not an ‘all-clear’ signal,” the authors wrote. “Obstetrician-gynecologists and other obstetric care providers should ensure that women, their families, and their employers understand that completion of the comprehensive postpartum visit does not obviate the need for continued recovery and support through 6 weeks’ post partum and beyond.”

Women with comorbidities or adverse birth outcomes

Women who had gestational diabetes, gestational hypertension, preeclampsia, eclampsia, or a preterm birth should be informed of their increased lifetime risk of cardiovascular and metabolic disease, the committee recommended. Women who have experienced a miscarriage, stillbirth, or neonatal death should also follow up with their provider, who can offer resources for emotional support and bereavement counseling, referrals as needed, a review of any laboratory or pathology results related to the loss and counseling regarding future risks and pregnancies.

The committee recommended that women with chronic medical conditions follow up with their ob.gyn. or other primary care providers to ensure ongoing coordinated care for hypertension, obesity, diabetes, thyroid disorders, renal disease, mood disorders, substance use disorders, seizure disorders, and any other chronic issues. Care should include assessment of medications, including antiepileptics and psychotropic drugs, that may require adjustment for postpartum physiology and, if relevant, breastfeeding.

Since half of postpartum strokes occur within the first 10 days after discharge, ACOG recommends women with other hypertensive disorders of pregnancy have a postpartum visit within 7-10 days after birth to assess blood pressure. A follow-up visit should occur within 72 hours for those with severe hypertension.

ACOG also recommended early postpartum follow-up for women with increased risk of complications, including postpartum depression, cesarean or perennial wound infections, lactation difficulties, or chronic conditions.

 

 


The committee opinion concluded with a call for public policy changes, including endorsement of guaranteed 100% paid parental leave for a minimum of 6 weeks with full benefits. Currently, 23% of employed mothers return to work in the first 10 days after giving birth, and another 22% return within 10-30 days, the committee cited. Close to half of employed mothers therefore go back to work before the 6-week postpartum follow-up visit.

“Obstetrician-gynecologists and other obstetric care providers should be in the forefront of policy efforts to enable all women to recover from birth and nurture their infants,” the committee wrote.

The ACOG Presidential Task Force on Redefining the Postpartum Visit and the Committee on Obstetrics Practice developed the new clinical opinion, which is endorsed by the Academy of Breastfeeding Medicine, the American College of Nurse-Midwives, the National Association of Nurse Practitioners in Women’s Health, the Society for Academic Specialists in General Obstetrics and Gynecology, and the Society for Maternal-Fetal Medicine. The committee opinion did not require external funding, and the authors did not report any disclosures.

Key clinical point: New recommendations on postpartum care advise earlier and more comprehensive follow-up visits and propose a new paradigm for ensuring the physical, emotional, and mental health of women in the first 12 weeks after giving birth.

Major finding: Women should have a follow-up visit within 3 weeks post partum – earlier if they have chronic conditions or had pregnancy complications – and an additional comprehensive visit no later than 12 weeks post partum.

Data source: The findings are based on an assessment of existing evidence on postpartum care, postpartum risks, and currently unfulfilled needs that ob.gyns. can and should fulfill, according to ACOG.

Disclosures: The committee opinion did not require external funding, and the authors did not report any disclosures.

Self-administration of subcutaneous belimumab could eliminate hospital visits for SLE patients

Patients with systemic lupus erythematosus (SLE) who were hypocomplementemic and anti–double-stranded DNA (anti-dsDNA) positive took weekly subcutaneous belimumab in addition to their standard therapy and saw reduced disease activity and fatigue at 1 year, compared with patients taking a placebo, according to results of a phase 3, double-blinded study. These results suggest the subcutaneous version of the monoclonal antibody therapy could be administered at home without patients visiting a hospital, the investigators wrote in Arthritis and Rheumatology.

“Intravenous administration of belimumab is an obstacle to treatment for many patients due to the need to go to the hospital for drug infusions. Thus, a higher number of patients could benefit from this treatment,” Andrea Doria, MD, from the University of Padua (Italy) stated in a press release. “The self-administration of subcutaneous belimumab makes hospital access unnecessary, which leads to economic savings for patients and the community.”

Dr. Doria and his colleagues randomized 356 patients with SLE who were hypocomplementemic (low C3 [less than 90 mg/dL] and/or low C4 [less than 10 mg/dL]) and anti-dsDNA+ (greater than or equal to 30 IU/mL) to receive weekly subcutaneous belimumab (200 mg) or placebo in a 2:1 allocation ratio in addition to standard SLE therapy. Patients had moderate to severe SLE as determined by a Safety of Estrogens in Lupus Erythematosus National Assessment–Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) score of 8 or higher.

Researchers set a primary endpoint of response rate according to SLE Responder Index (SRI4), no new British Isles Lupus Assessment Group organ domain A or B scores, and less than a 0.3 increase in Physician’s Global Assessment score at 52 weeks, compared with baseline scores; the secondary endpoints included corticosteroid use reduction between week 40 and week 52 of 25% or more to 7.5 mg/day or less, change in Functional Assessment of Chronic Illness Therapy–Fatigue score, and measurement of time to severe flare as measured by the SLE Flare Index.

At 52 weeks, 64.6% of patients in the belimumab group responded according to SRI4, compared with 47.2% of patients in the placebo group (P = .0014). The researchers attributed the high SRI4 response rate for the placebo group to “administration of SoC [standard SLE therapy]; increased chance of receiving active treatment due to the unbalanced randomization schedule, thereby resulting in a psychological benefit; and the high frequency of visits and patient satisfaction associated with clinical trials.”

Patients had lower flare rates according to the SLE Flare Index in the belimumab group (31.5%), compared with placebo (14.1%), and those in the former group had a 62% reduction in severe flares, compared with the placebo group (hazard ratio, 0.38; 95% confidence interval, 0.24-0.61; P less than .0001). More patients taking belimumab reduced their use of corticosteroids (20.7%) than did those taking the placebo (11.4%) (odds ratio, 2.08; 95% CI, 0.91-4.77; P = .0844). Of patients taking belimumab, 44.8% had a Functional Assessment of Chronic Illness Therapy–Fatigue score of 4 or higher at week 52, compared with 33.3% of patients taking placebo (OR, 1.82; 95% CI, 1.10-3.01; P = .0199).

Regarding adverse events, there were 88 (81.5%) adverse events in the placebo group, with 29 (26.9%) of those events considered to have occurred during treatment, compared with 79 of 194 (31.9%) adverse events attributed to treatment in the belimumab group. The researchers reported 25 patients in the placebo group (23.1%) and 33 patients in the belimumab group (13.3%) had serious adverse events. Postinjection systemic reactions occurred in 21 patients (8.5%) and 13 patients (12.0%) in the belimumab and placebo groups, respectively.

 

 


“Some aspects of this study were identified as potential limitations,” Dr. Doria and his colleagues wrote. “Within the hypocomplementemic and anti-dsDNA positive subset population, only 65.7% of patients received steroids greater than 7.5 mg/day at baseline; thus (as in the overall population), this endpoint was not powered for statistical significance. In addition, this study excluded patients with SELENA-SLEDAI less than 8, active nephritis, or active CNS disease at screening.”

The study was funded, conducted, and designed by GlaxoSmithKline. Five authors have shares in and are employees of GSK; another was an employee of GSK at the time of the study. Seven authors declared consulting fees, grants and other remuneration from pharmaceutical companies, including GSK.

Of patients taking belimumab, 44.8% had a Functional Assessment of Chronic Illness Therapy–Fatigue score of 4 or higher at week 52, compared with 33.3% of patients taking placebo (OR, 1.82; 95% CI, 1.10-3.01; P = .0199).

Regarding adverse events, there were 88 (81.5%) adverse events in the placebo group, with 29 (26.9%) of those events considered to have occurred during treatment, compared with 79 of 194 (31.9%) adverse events attributed to treatment in the belimumab group. The researchers reported 25 patients in the placebo group (23.1%) and 33 patients in the belimumab group (13.3%) had serious adverse events. Postinjection systemic reactions occurred in 21 patients (8.5%) and 13 patients (12.0%) in the belimumab and placebo groups, respectively.

 

 


“Some aspects of this study were identified as potential limitations,” Dr. Doria and his colleagues wrote. “Within the hypocomplementemic and anti-dsDNA positive subset population, only 65.7% of patients received steroids greater than 7.5 mg/day at baseline; thus (as in the overall population), this endpoint was not powered for statistical significance. In addition, this study excluded patients with SELENA-SLEDAI less than 8, active nephritis, or active CNS disease at screening.”

The study was funded, conducted, and designed by GlaxoSmithKline. Five authors have shares in and are employees of GSK; another was an employee of GSK at the time of the study. Seven authors declared consulting fees, grants and other remuneration from pharmaceutical companies, including GSK.

Patients with systemic lupus erythematosus (SLE) who were hypocomplementemic and anti–double-stranded DNA (anti-dsDNA) positive took weekly subcutaneous belimumab in addition to their standard therapy and saw reduced disease activity and fatigue at 1 year, compared with patients taking a placebo, according to results of a phase 3, double-blinded study. These results suggest the subcutaneous version of the monoclonal antibody therapy could be administered at home without patients visiting a hospital, the investigators wrote in Arthritis and Rheumatology.

“Intravenous administration of belimumab is an obstacle to treatment for many patients due to the need to go to the hospital for drug infusions. Thus, a higher number of patients could benefit from this treatment,” Andrea Doria, MD, from the University of Padua (Italy) stated in a press release. “The self-administration of subcutaneous belimumab makes hospital access unnecessary, which leads to economic savings for patients and the community.”

Dr. Doria and his colleagues randomized 356 patients with SLE who were hypocomplementemic (low C3 [less than 90 mg/dL] and/or low C4 [less than 10 mg/dL]) and anti-dsDNA+ (greater than or equal to 30 IU/mL) to receive weekly subcutaneous belimumab (200 mg) or placebo in a 2:1 allocation ratio in addition to standard SLE therapy. Patients had moderate to severe SLE as determined by a Safety of Estrogens in Lupus Erythematosus National Assessment–Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) score of 8 or higher.

Researchers set a primary endpoint of response rate according to SLE Responder Index (SRI4), no new British Isles Lupus Assessment Group organ domain A or B scores, and less than a 0.3 increase in Physician’s Global Assessment score at 52 weeks, compared with baseline scores; the secondary endpoints included corticosteroid use reduction between week 40 and week 52 of 25% or more to 7.5 mg/day or less, change in Functional Assessment of Chronic Illness Therapy–Fatigue score, and measurement of time to severe flare as measured by the SLE Flare Index.

At 52 weeks, 64.6% of patients in the belimumab group responded according to SRI4, compared with 47.2% of patients in the placebo group (P = .0014). The researchers attributed the high SRI4 response rate for the placebo group to “administration of SoC [standard SLE therapy]; increased chance of receiving active treatment due to the unbalanced randomization schedule, thereby resulting in a psychological benefit; and the high frequency of visits and patient satisfaction associated with clinical trials.”

Patients had lower flare rates according to the SLE Flare Index in the belimumab group (31.5%), compared with placebo (14.1%), and those in the former group had a 62% reduction in severe flares, compared with the placebo group (hazard ratio, 0.38; 95% confidence interval, 0.24-0.61; P less than .0001).

Gene therapy for thalassemia normalizes hemoglobin

Patients in developing countries could see benefit
Article Type

Fri, 01/04/2019 - 10:23

 

Most beta thalassemia patients were off transfusions at a median of 26 months after receiving gene therapy via a lentiviral vector, according to new results of two phase 1/2 studies regarding the use of LentiGlobin in transfusion-dependent beta thalassemia.

Of 13 patients who did not have the most severe beta0/beta0 genotype, all but 1 has become transfusion independent post transplant. Among patients who either had the beta0/beta0 genotype or had two copies of the IVS1-110 mutation, transfusions were down a median 73% annually, and three of these patients with more severe thalassemia became transfusion independent.

At the time of last data collection, hemoglobin levels in individual patients ranged from 8.2-13.7 g/dL.

“No clonal dominance related to vector integration was observed,” wrote Alexis Thompson, MD, and her collaborators, and replication-competent lentivirus had not been found in any patients.

Hematopoietic cell transplant (HCT) is an option primarily for younger beta thalassemia patients who have an HLA-matched sibling donor, the researchers wrote in the New England Journal of Medicine. Gene therapy represents an alternative to the current standard of care for patients who are not candidates for allogeneic HCT, which – without a good match – carries increased risk for rejection and graft-versus-host disease.

Patients with beta thalassemia aged 35 years or younger and without advanced organ damage were enrolled in the two studies, one conducted internationally and one conducted at a single site in France.

There were some protocol differences between the two studies; notably, the French study used enhanced red cell transfusion for 3 or more months before stem cell mobilization “to enrich for bona fide hematopoietic stem cells in the harvested CD34+ cell compartment by suppressing the erythroid lineage expansion and the skewing that is seen in beta thalassemia,” wrote Dr. Thompson, professor of pediatrics at Northwestern University, Chicago, and her colleagues.

 

 


In both studies, after mobilization, patients’ unmanipulated hematopoietic stem cells and progenitor cells were taken to a central processing facility, where CD34+ cells were enriched and then transduced with the lentiviral vector BB305, which encodes adult hemoglobin (HbA) with a T87Z amino acid substitution and thereby provides functioning Hb beta. Patients received the product via infusion after undergoing myeloablative conditioning with busulfan.

A total of 23 patients, 19 in the international study and 4 in the French study, went through mobilization and apheresis. One patient in the international study had apheresis failure, so a total of 22 patients received LentiGlobin, and all were followed for up to 2 years.

Patients were given the opportunity to participate in a follow-on open label study meant to continue for an additional 13 years after the initial 24-month period; 13 patients are currently enrolled in this long-term follow-up study.

When transfusion volume at baseline was assessed, patients in the international study were receiving a median annual red blood cell transfusion volume of 164 mL/kg per year, while the French study participants were receiving a median 182 mL/kg per year of red blood cell transfusion.
 

 


In both studies, blood HbAT87Q levels correlated with the vector copy numbers (R2, 0.75; P less than .001). Levels of HbAT87Q ranged from 3.4-10.0 g/dL.

“Other factors, such as age, genotype, and splenectomy status, did not appear to correlate with gene expression,” the researchers wrote.

An exploratory analysis looked at characteristics of patients who were able to stop transfusions after gene therapy. In this group, “the degree of hemolysis at first stabilized relative to pretransplantation levels and was fully corrected” in two patients by 36 months after treatment.

The researchers noted that the sponsor achieved “high-titer, large-scale, clinical-grade BB305 vector production and purification by ion-exchange chromatography” from a single site in the United States, which showed the feasibility of conducting this modality of gene therapy at scale.

The study was sponsored by bluebird bio, the National Institutes of Health, and by French national research organizations. Dr. Thompson reported research funding and fees from bluebird bio and other pharmaceutical companies.

Lentiviral vector hematopoietic stem cell (HSC) gene therapy represents a promising alternative to matched-sibling donor HSC transplants for treatment of beta thalassemia, with studies to date showing a safety profile that surpasses transplants from unrelated or alternative donors.

The prospect of a curative treatment raised by the work of Dr. Thompson and her colleagues also shows the feasibility of transfusion independence for beta0/betaE patients, who carry the most common beta thalassemia genotype, and a significant reduction in transfusions even for patients with the more severe beta0/beta0 genotype.

Beta thalassemia has greatest prevalence in North Africa, the Middle East, and Asia, where access to treatments is limited and patients’ prognoses are often grim. Gene therapy for beta thalassemia could thereby represent the first large-scale implementation of this intervention in developing countries.

Bringing HSC gene therapy to more patients will require not just the availability of autologous HSCs, but of high-quality vector and reliable, high-volume manufacturing of transduced cells.

Harnessing this still-evolving technology to bring a potentially curative treatment to patients in developing countries is an exciting, but challenging, frontier for physicians and researchers involved with gene therapy.

Impaired kidney function no problem for dabigatran reversal

– Idarucizumab, the reversal agent for the anticoagulant dabigatran, appeared as effective in quickly reversing dabigatran’s effects in patients with severe renal dysfunction as in patients with normally working kidneys, in a post hoc analysis of data collected in the drug’s pivotal trial.

A standard dose of idarucizumab “works just as well in patients with bad kidney function as it does in patients with preserved kidney function,” John W. Eikelboom, MD, said at the annual meeting of the American College of Cardiology. “The time to cessation of bleeding and the degree of normal hemostasis achieved was consistent” across the entire range of renal function examined, from severe renal dysfunction, with a creatinine clearance rate of less than 30 mL/min, to normal function, with an estimated rate of 80 mL/min or greater.

Dr. John W. Eikelboom

The ability of idarucizumab (Praxbind), conditionally approved by the Food and Drug Administration in 2015 and then fully approved in April 2018, to work in patients with impaired renal function has been an open question and concern because dabigatran (Pradaxa) is excreted renally, so it builds to unusually high levels in patients with poor kidney function. “Plasma dabigatran levels might be sky high, so a standard dose of idarucizumab might not work. That’s been a fear of clinicians,” explained Dr. Eikelboom, a hematologist at McMaster University in Hamilton, Ont.

To examine whether idarucizumab’s activity varied by renal function he used data from the patients enrolled in the RE-VERSE AD (Reversal Effects of Idarucizumab on Active Dabigatran) study, the pivotal dataset that led to idarucizumab’s U.S. approval. The new, post hoc analysis divided patients into four subgroups based on their kidney function, and focused on the 489 patients for whom renal data were available out of the 503 patients in the study (N Engl J Med. 2017 Aug 3;377[5]:431-41). The subgroups included 91 patients with severe dysfunction with a creatinine clearance rate of less than 30 mL/min; 127 with moderate dysfunction and a clearance rate of 30-49 mL/min; 163 with mild dysfunction and a clearance rate of 50-79 mL/min; and 108 with normal function and a creatinine clearance of at least 80 mL/min.



Patients in the subgroup with severe renal dysfunction had the worst clinical profile overall, and as predicted, had a markedly elevated average plasma level of dabigatran, 231 ng/mL, nearly five times higher than the 47-ng/mL average level in patients with normal renal function.

The ability of a single, standard dose of idarucizumab to reverse the anticoagulant effects of dabigatran were essentially identical across the four strata of renal activity, with 98% of patients in both the severely impaired subgroup and the normal subgroup having 100% reversal within 4 hours of treatment, Dr. Eikelboom reported. Every patient included in the analysis had more than 50% reversal.

The study followed patients to 12-24 hours after they received idarucizumab, and 55% of patients with severe renal dysfunction showed a plasma dabigatran level that crept back toward a clinically meaningful level and so might need a second idarucizumab dose. In contrast, this happened in 8% of patients with normal renal function.

 

 


In patients with severe renal dysfunction given idarucizumab, “be alert for a recurrent bleed,” which could require a second dose of idarucizumab, Dr. Eikelboom suggested.

The ability of a single, standard dose of idarucizumab to reverse the anticoagulant effects of dabigatran were essentially identical across the four strata of renal activity, with 98% of patients in both the severely impaired subgroup and the normal subgroup having 100% reversal within 4 hours of treatment, Dr. Eikelboom reported. Every patient included in the analysis had more than 50% reversal.

The study followed patients to 12-24 hours after they received idarucizumab, and 55% of patients with severe renal dysfunction showed a plasma dabigatran level that crept back toward a clinically meaningful level and so might need a second idarucizumab dose. In contrast, this happened in 8% of patients with normal renal function.

– Idarucizumab, the reversal agent for the anticoagulant dabigatran, appeared as effective in quickly reversing dabigatran’s effects in patients with severe renal dysfunction as in patients with normally working kidneys, in a post hoc analysis of data collected in the drug’s pivotal trial.

A standard dose of idarucizumab “works just as well in patients with bad kidney function as it does in patients with preserved kidney function,” John W. Eikelboom, MD, said at the annual meeting of the American College of Cardiology. “The time to cessation of bleeding and the degree of normal hemostasis achieved was consistent” across the entire range of renal function examined, from severe renal dysfunction, with a creatinine clearance rate of less than 30 mL/min, to normal function, with an estimated rate of 80 mL/min or greater.

The ability of idarucizumab (Praxbind), conditionally approved by the Food and Drug Administration in 2015 and then fully approved in April 2018, to work in patients with impaired renal function has been an open question and concern because dabigatran (Pradaxa) is excreted renally, so it builds to unusually high levels in patients with poor kidney function. “Plasma dabigatran levels might be sky high, so a standard dose of idarucizumab might not work. That’s been a fear of clinicians,” explained Dr. Eikelboom, a hematologist at McMaster University in Hamilton, Ont.

To examine whether idarucizumab’s activity varied by renal function he used data from the patients enrolled in the RE-VERSE AD (Reversal Effects of Idarucizumab on Active Dabigatran) study, the pivotal dataset that led to idarucizumab’s U.S. approval. The new, post hoc analysis divided patients into four subgroups based on their kidney function, and focused on the 489 patients for whom renal data were available out of the 503 patients in the study (N Engl J Med. 2017 Aug 3;377[5]:431-41). The subgroups included 91 patients with severe dysfunction with a creatinine clearance rate of less than 30 mL/min; 127 with moderate dysfunction and a clearance rate of 30-49 mL/min; 163 with mild dysfunction and a clearance rate of 50-79 mL/min; and 108 with normal function and a creatinine clearance of at least 80 mL/min.



Patients in the subgroup with severe renal dysfunction had the worst clinical profile overall, and as predicted, had a markedly elevated average plasma level of dabigatran, 231 ng/mL, nearly five times higher than the 47-ng/mL average level in patients with normal renal function.

Key clinical point: Renal function had no impact on idarucizumab’s efficacy for dabigatran reversal.

Major finding: Complete dabigatran reversal occurred in 98% of patients with severe renal dysfunction who received idarucizumab.

Study details: Post hoc analysis of data from RE-VERSE AD, idarucizumab’s pivotal trial with 503 patients.

Disclosures: RE-VERSE AD was funded by Boehringer Ingelheim, the company that markets idarucizumab (Praxbind) and dabigatran (Pradaxa). Dr. Eikelboom has been a consultant to and has received research support from Boehringer Ingelheim, as well as from Bayer, Bristol-Myers Squibb, Daiichi-Sankyo, Janssen, and Pfizer.

Randomized Phase 3 Trial Evaluating the Addition of the IGF-1R Monoclonal Antibody Ganitumab (AMG 479, NSC# 750008) to Multiagent Chemotherapy for Patients With Newly Diagnosed Metastatic Ewing Sarcoma

NCT02306161

Sponsor: National Cancer Institute (NCI)

Principal Investigator: Steven DuBois, Children’s Oncology Group and Dana-Farber Cancer Institute, Boston.

Study locations: Over 300 U.S. cancer centers

Study summary: This randomized phase 3 trial examines whether the monoclonal antibody ganitumab plus combination chemotherapy (vincristine sulfate, doxorubicin hydrochloride, cyclophosphamide, ifosfamide, and etoposide) improves event-free survival for patients with newly-diagnosed, metastatic Ewing sarcoma. Secondary outcomes include overall survival rate and comparative evaluations of toxicity.

Patients are randomized to induction and consolidation therapy with vincristine sulfate, doxorubicin hydrochloride and cyclophosphamide [VDC] and ifosfamide and etoposide [IE]) or to the same regimen plus ganitumab. Between weeks 13-18 of the trial, patients undergo surgery and/or radiation therapy for local control. Patients with lung metastases undergo definitive stereotactic body radiation therapy or external beam radiation therapy over 5 days.

Study inclusion summary: Patients up to 50 years old are eligible to participate in this trial if they have newly-diagnosed Ewing sarcoma or peripheral primitive neuroectodermal tumor (PNET) arising from bone or soft tissue and with metastatic disease involving lung, bone, bone marrow, or other metastatic site. Submission of pre-treatment serum, tumor tissue and whole blood is required. Patients should only have had a biopsy of the primary tumor without an attempt at complete or partial resection; patients will still be eligible if excision was attempted or accomplished as long as adequate anatomic imaging (MRI for most primary tumor sites) was obtained prior to surgery. Creatinine clearance or radioisotope glomerular filtration rate (GFR) must be at least 70 mL/min/1.73 m2 or greater. Total bilirubin must be less than 1.5 times the upper limit of normal, alanine aminotransferase must be less than 3 times the upper limit of normal, blood sugar must be normal, and heart ejection fraction must exceed 50%.

Induction therapy: Patients receive vincristine sulfate intravenously (IV) over 1 minute on day 1; doxorubicin hydrochloride IV over 1-15 minutes on days 1 and 2; and cyclophosphamide IV over 30-60 minutes on day 1 of weeks 1, 5, and 9; and ifosfamide IV over 1 hour on days 1 to 5 and etoposide IV over 1-2 hours on days 1 to 5 of weeks 3, 7, and 11. Patients in the control group receive induction therapy and placebo and patients in the treatment group receive induction therapy and ganitumab IV over 30-60 minutes or 60-120 minutes on day 1 of weeks 1, 3, 5, 7, 9, and 11.

Consolidation therapy: Patients receive vincristine sulfate IV over 1 minute on day 1 of weeks 1, 7, 9, and 13; doxorubicin hydrochloride IV over 1-15 minutes on days 1 and 2 of weeks 1 and 7; cyclophosphamide IV over 30-60 minutes on day 1 of weeks 1, 7, 9, and 13; ifosfamide IV over 1 hour on days 1 to 5 of weeks 3, 5, 11, and 15; and etoposide IV over 1-2 hours on days 1 to 5 of weeks 3, 5, 11, and 15. In addition to this standard consolidation therapy, pPatients in the active treatment group receive ganitumab IV over 30-60 minutes or 60-120 minutes on day 1 of weeks 7, 9, 11, 13, and 15.

Maintenance therapy: Patients receive ganitumab IV over 30-60 minutes or 60-120 minutes on day 1 in weeks 1, 4, 7, 10, 13, 16, 19, and 22.

Follow up: After completion of study treatment, patients are followed for 10 years.

Sponsor: National Cancer Institute (NCI)

Principal Investigator: Abha Gupta, Children’s Oncology Group, The Hospital for Sick Children and Princess Margaret Cancer Centre.

Study locations: 293 cancer centers in the U.S. and Canada

Study summary: This randomized phase 3 trial compares standard combination chemotherapy with and without temsirolimus for patients with rhabdomyosarcoma that has an intermediate chance of recurrence after treatment. It is not yet known whether combination chemotherapy or combination chemotherapy plus temsirolimus is more effective in treating patients with intermediate-risk rhabdomyosarcoma.

Study inclusion summary: Patients up to age 40 with newly diagnosed RMS of any subtype, except adult-type pleomorphic, based upon institutional histopathologic classification, are eligible to enroll on the study. Lansky performance status score must be at least 50 for patients age 16 years and under; Karnofsky performance status score must be 50 or greater for patients over age 16. Peripheral absolute neutrophil count must be at least 750/uL and platelet count at least 75,000/uL. Creatinine clearance or radioisotope glomerular filtration rate must be at least 70 mL/min/1.73 m2. Total bilirubin must be no more than 1.5 times the upper limit of normal for patient age.

Treatment regimen: Patients are randomized to one of three study arms. One group receives vincristine sulfate IV over 1 minute on day 1 of weeks 1-13, 16, 17, 19, 20, 22-26, 28, 31-34, 37, 38, and 40, dactinomycin IV over 1-5 minutes on day 1 of weeks 1, 7, 13, 22, 28, 34, and 40, cyclophosphamide IV over 60 minutes on day 1 of weeks 1, 7, 13, 22, 28, 34, and 40, irinotecan hydrochloride IV over 90 minutes on days 1-5 of weeks 4, 10, 16, 19, 25, 31, and 37. The second group receives the same regimen plus temsirolimus IV over 30-60 minutes on day 1 of weeks 1-12 and 21-42. The third group receives vincristine sulfate IV over 1 minute on day 1 of weeks 1-10 and 13-22, dactinomycin IV over 1-5 minutes on day 1 of weeks 1, 4, 7, 10, 13, 16, 19, and 22, cyclophosphamide IV over 60 minutes on day 1 of weeks 1, 4, 7, and 10. Patients in all three groups also undergo radiation therapy beginning at week 13 for 6 weeks. Treatment continues in all three groups in the absence of disease progression or unacceptable toxicity.

Outcome Measures: The primary outcome measure is event-free survival (EFS) measured from study enrollment to the first occurrence of progression, relapse, second malignant neoplasm, or death as a first event. The secondary outcome measure is overall survival measured from study enrollment to death from any cause, assessed up to 10 years. TSJ

Picosecond 755-nm laser found effective for neck rejuvenation

A picosecond 755-nm laser with focus lens array can serve as a safe, nonsurgical option for neck rejuvenation in patients with Fitzpatrick skin types I-III, especially for those who seek treatments with minimal downtime.

“It’s important to note that response was variable, but many patients were satisfied with the treatment,” Hana Jeon, MD said at the annual conference of the American Society for Laser Medicine and Surgery, Inc. “Further studies are needed to identify the clinical characteristics of neck laxity that would most benefit from this treatment.”

Hana Jeon, MD
A patient before treatment with a picosecond 755-nm laser for neck rejuvenation.
Dr. Jeon, a dermatologist at the Laser & Skin Surgery Center of New York, and her associates examined the safety and efficacy of the treatment of skin laxity on the neck using a picosecond 755-nm laser with focus lens array, which uses a diffractive lens to redistribute the energy at both low- and high-intensity energies. “High-intensity energy leads to cellular changes, which then results in dermal remodeling,” she said. “This technology has been shown to be helpful for acne scar treatment and skin rejuvenation. A big advantage of this technology is that there is really no downtime other than transient erythema. Given that both collagen and elastin have been shown to increase over time after treatment, we decided to evaluate its role in treating neck laxity.”

The researchers enrolled 25 patients with an average age of 58 years. The laser treatment settings were a 6-mm spot side-delivered at a fluence of 0.71 J/cm2 in a pulse width of 750 picoseconds. The patients were treated five times on the neck every 2-4 weeks, and follow-up visits were scheduled for 1 month and 3 months after the last treatment. Digital photos were taken at each visit. Formal assessment tools included patient and physician satisfaction scores and the Global Aesthetic Improvement Scale. In all, 21 women and 3 men completed the study. The majority (72%) had Fitzpatrick skin type II, while 16% had type III, 8% had type I, and 4% had type IV. An average of 5,042 pulses were delivered during each treatment session. The majority of patients (84%) required no anesthesia, while the rest used topical numbing medicine from 30 minutes to an hour prior to the procedure.



Dr. Jeon reported that the average pain score during the procedure was 4.7 on a 10-point scale. Forced-air cooling was used for comfort, and on average, mild redness following the treatment lasted less than 1 day (a mean of 0.6 days, with a range of 0-5 days). Mild pain also lasted less than 1 day (a mean of 0.1 days, with a range of 0-2 days). No swelling, crusting, bruising, bleeding, infection, blistering, scarring, burn, or dyspigmentation occurred.

Hana Jeon, MD
The same patient, one month after treatment with a picosecond 755-nm laser for neck rejuvenation.
Analysis of satisfaction scores at 3-month follow-up revealed that 43% of patients and 36% of physicians, respectively, felt “neutral” about the results, 30% and 27%, respectively, reported being “satisfied” with the results, and 13% and 14%, respectively, reported being “extremely satisfied” with the results.

On the Global Aesthetic Improvement Scale at 1 and 3 months, physicians described 43% and 23% of cases, respectively, as “improved,” 17% and 18% of cases as “much improved,” and 4% and 9% of cases as “extremely improved.”

 

 


At 3 months, 35% of patients said they would be “somewhat likely” to recommend the procedure, and 30% said they would be “extremely likely” to recommend it.

A picosecond 755-nm laser with focus lens array can serve as a safe, nonsurgical option for neck rejuvenation in patients with Fitzpatrick skin types I-III, especially for those who seek treatments with minimal downtime.

“It’s important to note that response was variable, but many patients were satisfied with the treatment,” Hana Jeon, MD said at the annual conference of the American Society for Laser Medicine and Surgery, Inc. “Further studies are needed to identify the clinical characteristics of neck laxity that would most benefit from this treatment.”

Dr. Jeon, a dermatologist at the Laser & Skin Surgery Center of New York, and her associates examined the safety and efficacy of the treatment of skin laxity on the neck using a picosecond 755-nm laser with focus lens array, which uses a diffractive lens to redistribute the energy at both low- and high-intensity energies. “High-intensity energy leads to cellular changes, which then results in dermal remodeling,” she said. “This technology has been shown to be helpful for acne scar treatment and skin rejuvenation. A big advantage of this technology is that there is really no downtime other than transient erythema. Given that both collagen and elastin have been shown to increase over time after treatment, we decided to evaluate its role in treating neck laxity.”

The researchers enrolled 25 patients with an average age of 58 years. The laser treatment settings were a 6-mm spot side-delivered at a fluence of 0.71 J/cm2 in a pulse width of 750 picoseconds. The patients were treated five times on the neck every 2-4 weeks, and follow-up visits were scheduled for 1 month and 3 months after the last treatment. Digital photos were taken at each visit. Formal assessment tools included patient and physician satisfaction scores and the Global Aesthetic Improvement Scale. In all, 21 women and 3 men completed the study. The majority (72%) had Fitzpatrick skin type II, while 16% had type III, 8% had type I, and 4% had type IV. An average of 5,042 pulses were delivered during each treatment session. The majority of patients (84%) required no anesthesia, while the rest used topical numbing medicine from 30 minutes to an hour prior to the procedure.



Dr. Jeon reported that the average pain score during the procedure was 4.7 on a 10-point scale. Forced-air cooling was used for comfort, and on average, mild redness following the treatment lasted less than 1 day (a mean of 0.6 days, with a range of 0-5 days). Mild pain also lasted less than 1 day (a mean of 0.1 days, with a range of 0-2 days). No swelling, crusting, bruising, bleeding, infection, blistering, scarring, burn, or dyspigmentation occurred.

Infections predispose patients to developing Sjögren’s

Article Type

Sat, 12/08/2018 - 14:57

Present infections make patients more likely to develop primary Sjögren’s syndrome, according to a study presented at an International Symposium on Sjögren’s Syndrome.

“We observed a consistent association between infections and the subsequent development of primary Sjögren’s syndrome,” said Johannes Mofors of the department of medicine at the Karolinska University Hospital, Stockholm, in his presentation. “Infections of certain anatomical sites have different associations to Sjögren’s.”

With risk measurements primarily reliant on detecting the presence of MHC genes, this knowledge could be helpful in identifying at-risk patients and give physicians the chance to act before the syndrome emerges, according to Mr. Mofors.

Investigators conducted a retrospective, multicenter, controlled cohort study of 9,993 Swedish individuals from the country’s national patient registry to observe the association between infections and Sjögren’s.

Patients were an average age of 55 years, with either an SSA or SSB infection, with an average observational period of 16 years before diagnosis.

Of the patients with Sjögren’s disease, 21% reported one or more infections prior to diagnosis, compared with 12% among the control group.

When assessing patients by their type of infection, Mr. Mofors and his colleagues found the likelihood of developing Sjögren’s varied depending on which infection was present.

 

 

“We looked at respiratory infections, with the SSA/Ro-, SSB/Ro-positive patients having a stronger association than the corresponding rate of SSA-, SSB-negative patients,” explained Mr. Mofors. “Interestingly, as we looked at patients with skin infections, we observed an association with the SSA-, SSB-positive patients having a stronger association than the negative patients.”

Investigators also tested gastrointestinal infections, but found no clear association to Sjögren’s.

Presence of more than one infection also appeared to increased disposition of patients to Sjögren’s syndrome, although it depended on the type of infection, Mr. Mofors said at the meeting, which was sponsored by Johns Hopkins University and the National Institutes of Health.

Patients with multiple respiratory infections showed a stronger association to Sjögren’s, patients with SSA- or SSB-positive infection displaying even stronger prevalence, and patients with skin infections showed a dose-response pattern.
 

 

Patients with SSA or SSB pattern showed no significant association.

It is possible, said Mr. Mofors, that patients became more susceptible to infection as their Sjögren’s manifested, so investigators extended the omission period of their study from 3 to 7 years.

“As the omission period was extended, in the aggregated group of cases we saw a less prominent association; however, for the respiratory infections the change in relationship was insignificant,” said Mr. Mofors.

For SSA- and SSB-negative patients, the association between infections and predisposition to Sögren’s was not significant when the omission period was extended.

Mr. Mofors reported no relevant financial disclosures.

With these pearls, the med-tech space can be your oyster

– Having a great idea is just the first step to landing a financial partner in device development – backers also scrutinize more intangible qualities.

The willingness to work as part of a team, the ability to project realistic expectations, the fortitude to take risks and persevere when circumstances get tough – these attributes are critical to forging a strong strategic alliance with a financial partner, Brian Tinkham said at the 2018 AGA Tech Summit, sponsored by the AGA Center for GI Innovation and Technology.

“Some of the brightest physician minds in the world are not the best med-tech device engineers,” said Mr. Tinkham, vice president of sales in GI Solutions at Medtronic. “When you enter the space of med-tech development, you have to join a cross-functional team. You’ll need skill sets that aren’t instinctive to you or your closed network in order to become successful.”

Mr. Tinkham offered what he called “practical pearls” for securing the financial backing every physician entrepreneur needs to bring an idea to the marketplace.
 

Put your own skin in the game

“To me, ‘skin in the game’ is mainly money. Investing your own money, your family’s money, changes the way you behave at the board meeting and when you spend that money,” Mr. Tinkham said. “We like people who are all in on this. When I see an entrepreneur who’s showing a return that’s not good enough for his own investment, I can lose confidence and trust. We want people who won’t walk away from their money, their family’s money, or my money; when times get tough and challenging, decisions need to be made.”

Be realistic

There’s a difference between confidence and irrational confidence, Mr. Tinkham said. “If you come to me presenting a game plan that says you’ll have a commercially viable product in 1 year for a $500,000 investment, you’ll shoot your credibility right off. We know exactly how hard it is to build a $10 million business, never mind a $100 million business. When you obviously don’t understand what lies ahead of you, it hurts your credibility. Work with people who have experience and let them help you present your ideas and goals in a realistic way, and that will help with raising capital so you can execute your plan.”

Be capital efficient

“The key takeaway here is that raising $100 million doesn’t necessarily make for a strong return for investors. The strong return comes with $20-$40 million raised. Most likely businesses that have raised that much have built a commercial structure, provided proof of concept with some actual sales, and generated enough customer interest to attract strategic partners.”

 

 

Location, location, location

“This is so important when you’re developing technology: You need to know where the people with high levels of competency are, and where the money is. If you don’t live near these localities, get on a plane and get there – that’s where the business is being done.”

California and the Philadelphia-Boston-New York corridor are the two biggest med-tech and investor hot spots in the United States, Mr. Tinkham noted. Smaller centers of innovation are scattered around the country, including Seattle, Denver, Minneapolis, Chicago, Pittsburgh, Washington, Raleigh-Durham, Atlanta, Austin, and Phoenix.
 

Be patient

“Adopting a new technology takes time, and the more disruptive the idea, the longer it takes to achieve market adoption. Translating that into med-tech, the time from founding a company to exit will take more than 5 years. Only 10% of companies do it in less time than that,” Mr. Tinkham said. “And you have to remember that not all of the exits we see are good ones – they can be exits in which investors lose most of the capital they’ve brought into the company.”

De-risk

Be the entrepreneur who takes a vision to a viable product.

“Most physician entrepreneurs come up with an idea and protect it – but don’t move it further. We want to see an idea that’s been created and then de-risked. You protect it, you prototype it, go into preclinical studies, then clinically validate it or obtain regulatory approval. And then in the end, to us the best measure is your revenue. Are customers buying it? Do they see in it the same value that you, the entrepreneur, sees? If you can get it there, you’ve got something. The further you de-risk something, the more attractive you become.”

Evidence is essential but not sufficient to move guidelines

Article Type

– For those considering how to navigate their innovative health care strategy into a position that will lead to an eventual guideline recommendation, it is important to think beyond demonstration of efficacy and safety in the design of randomized trials, according to an overview of how guideline committees currently function.

“In the old days, it was only the strength of the evidence. Now, in addition to the evidence, we have three other issues we look at to form the strength of a recommendation,” John M. Inadomi, MD, AGAF, head of the division of gastroenterology, University of Washington, Seattle, said at the 2018 AGA Tech Summit, sponsored by the AGA Center for GI Innovation and Technology.

These additional considerations include patient preferences, the balance of harms and benefits, and the resources consumed, according to Dr. Inadomi, who has participated in several guideline committees. All three issues for any new strategy must be considered in the context of alternative management. By itself, positive outcomes from a randomized controlled trial are not enough to guarantee a strong guideline recommendation.

“I think the big thing is that we are trying to move away from is just-the-evidence [approach],” Dr. Inadomi explained to an audience that included physician entrepreneurs and investors with an interest in how to establish a new diagnostic tool or treatment device as a standard of care.

There is no doubt that randomized controlled trial data are critical for objectively establishing safety and efficacy, but there has been an evolutionary change. According to Dr. Inadomi, guideline committees are posing more pointed questions about the practical value of one strategy relative to others. They also have increased their scrutiny of the quality and consistency of the RCT data in relation to the specific indication being considered.

“The implication of a strong recommendation is that most people in the situation would want the recommended course of action and that only a small proportion would not,” Dr. Inadomi explained. On the basis of this criterion, an inconvenient, costly, or poorly accepted therapy may not receive a strong recommendation even if effective. Strong recommendations typically set a standard.

“For the health care provider, that means that most patients should receive that course of action,” Dr. Inadomi said. Conversely, “for a weak recommendation, it implies that the majority of people would want this, but many would not.”

 

 


Strong versus weak recommendations have an impact on health care policy, Dr. Inadomi added. Those measuring quality of care might, in some cases, evaluate the frequency with which patients receive guideline-based care that has been given a 1A rating, which identifies the strongest recommendation. Weak recommendations encourage a greater emphasis on shared decision making that recognizes alternative treatment strategies in the context of patient preferences and values.

A reorientation that considers the limits of objective data by itself is reflected in a less restrictive view on the source of the data used in guideline deliberations, according to Dr. Inadomi. “It was once thought that all RCTs are good and observational studies are bad,” he said, adding that this view has changed with greater appreciation of publication bias and RCT study limitations, such as enrollment of nonrepresentative patient populations. While RCT data are preferred, he contended that observational studies are influential to guideline committees when there is a large effect size and there is consistency of evidence.

The move away from evidence-only guidelines is driven by a greater appreciation of value, Dr. Inadomi suggested. For entrepreneurs who hope to shepherd their devices or tools into a central position in clinical medicine, safety and efficacy are critical but may no longer be sufficient.

Dr. Inadomi has no disclosures relevant to this topic.

– For those considering how to navigate their innovative health care strategy into a position that will lead to an eventual guideline recommendation, it is important to think beyond demonstration of efficacy and safety in the design of randomized trials, according to an overview of how guideline committees currently function.

“In the old days, it was only the strength of the evidence. Now, in addition to the evidence, we have three other issues we look at to form the strength of a recommendation,” John M. Inadomi, MD, AGAF, head of the division of gastroenterology, University of Washington, Seattle, said at the 2018 AGA Tech Summit, sponsored by the AGA Center for GI Innovation and Technology.

These additional considerations include patient preferences, the balance of harms and benefits, and the resources consumed, according to Dr. Inadomi, who has participated in several guideline committees. All three issues for any new strategy must be considered in the context of alternative management. By itself, positive outcomes from a randomized controlled trial are not enough to guarantee a strong guideline recommendation.

“I think the big thing is that we are trying to move away from is just-the-evidence [approach],” Dr. Inadomi explained to an audience that included physician entrepreneurs and investors with an interest in how to establish a new diagnostic tool or treatment device as a standard of care.

Physiology, not mechanics, explains benefit of bariatric procedures

– Rather than being a better strategy to block absorption of ingested calories, the future of bariatric surgery depends on treatment combinations that promote weight control through healthy physiology, according to three experts participating in a panel on this topic at the 2018 AGA Tech Summit, sponsored by the AGA Center for GI Innovation and Technology.

“When we think about the mechanisms of surgery, the mechanical model is dead. There is no good supporting evidence for the mechanical model. The current model is all physiological, involving changes in signaling from the gut to the rest of the body,” asserted Lee Kaplan, MD, PhD, AGAF, director of the Weight Center at Massachusetts General Hospital, Boston.

Robert Lodge/MDedge News
Essentially all bariatric surgery and bariatric endoscopic devices block or restrict absorption of food in an effort to achieve weight loss by mechanically obstructing food absorption. However, Dr. Kaplan said mechanics do not explain what is observed clinically.

The list of evidence suggesting that change in physiologic function is a far more important explanation for weight loss from bariatric interventions is long, according to Dr. Kaplan. Of his many examples, he noted that pregnant women gain weight normally after bariatric surgery.

“Now, if you cannot absorb food normally after bariatric surgery, how do you gain weight normally when pregnant?” Dr. Kaplan asked. The answer to this and other examples of a disconnect between a simple food-blocking mechanism and what is observed is that bariatric procedures favorably alter signals that control hunger, satiety, and metabolism.

The two other experts on the panel largely agreed. In discussing advances in small-bowel devices for the treatment of type 2 diabetes mellitus, Christopher Thompson, MD, AGAF, director of therapeutic endoscopy at Brigham and Women’s Hospital, Boston, also looked to physiologic effects of bariatric surgery. He placed particular emphasis on the foregut and hindgut hypotheses. These hypotheses are “not yet written in stone,” but they provide a conceptual basis for understanding metabolic changes observed after bariatric procedures.

“One way that gastric bypass might work is that it alters the incretins that drive insulin secretion and sensitivity,” Dr. Thompson said. The same principle has been proposed for a novel incisionless magnetic device developed by Dr. Thompson that is now in clinical trials. The device, which creates an anastomosis and a partial jejunal diversion, achieved a 40% excess weight loss and a significant reduction in hemoglobin A1c levels among patients with type 2 diabetes mellitus in an initial study. Dr. Thompson contended that this effect cannot be explained by a change in nutrient absorption.

 

 


A surgeon serving on the panel, Marina Kurian, MD, of New York University’s Langone Medical Center, New York, also referenced the evidence for physiologic effects when speaking about gastric bypass and sleeve gastrectomy. Although both involve a blocking function for food absorption, she agreed that there are several reasons why this may not account for benefits.

“Certainly with gastric bypass, we talk about foregut and hindgut theory in terms of incretin effect,” Dr. Kurian said. She also noted that even the procedures that produce the greatest restriction on food absorption are not typically effective as a single therapeutic approach. Rather, her major point was that no approach, whether surgical, endoscopic, or lifestyle, is generally sufficient to achieve and maintain weight loss indefinitely. In her own practice, she has been moving to a “one-stop shopping” approach to coordinate multiple options.

“Those of us working in obesity are very aware of its chronicity and how one intervention is not enough,” Dr. Kurian said. She suggested that coordinated care among surgeons, gastroenterologists, dietitians, behavioral therapists, and others will provide the road forward even if the next set of surgical procedures or endoscopic devices are incrementally more effective than current options for weight loss.

One reason that a single intervention may not be enough is that obesity is not a single disease but the product of multiple different pathological processes, according to Dr. Kaplan. This is supported by the varied response to current therapies. Producing a variety of examples, he showed that, although there are large weight reductions with the most successful therapies, some patients are exceptional responders, while a proportion of patients lose little or no weight and others actually gain weight. He expressed doubt that there will be a single solution applicable to all patients.

 

 


“Patients who respond to one therapy may not respond to another and vice versa, and so the goal is to match each patient with the therapy that is most appropriate and protective for them,” Dr. Kaplan said.

GIs are uniquely positioned to lead a care team to help patients with obesity achieve a healthy weight. The POWER (Practice Guide on Obesity and Weight Management, Education and Resources) white paper provides physicians with a comprehensive, multidisciplinary process to guide and personalize innovative obesity care for safe and effective weight management.
