Obsessive-compulsive disorder

Case summary

Owen, an 8-year-old boy, is brought to his pediatrician by his mother. She has noticed that Owen is spending increasing amounts of time doing some repetitive behaviors such as counting to himself and needing to tap particular objects a specified number of times. Certain numbers seem to have special significance, and Owen has expressed some vague concern that something bad could happen if he does not do these behaviors. The rituals are starting to impact his schoolwork, as he often can get "stuck" during assignments. The mother is aware that many kids have some superstitions and wants to know if this is "something more."

Discussion

Obsessive-compulsive disorder (OCD) is a relatively common condition that can respond quite well to treatment. This case example outlines an approach that pediatricians can take to its diagnosis and management in a primary care setting.

Diagnosis

The diagnosis of OCD, according to DSM-5, requires the presence of distressing or impairing obsessions or compulsions. The definition didn’t change much from DSM-IV. Obsessions in children can revolve around things like contamination, disturbing thoughts of harm coming to others, sexual thoughts, or special numbers or words. Compulsions can include rituals with washing, checking, counting, arranging, and hoarding, among other behaviors.

When beginning to evaluate for possible OCD, it is important to talk to both the child and the parent, as it is common for parents to be unaware of the extent of the problem. An instrument called the Children’s Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) is considered to be the standard in the quantitative assessment of OCD. The rating scale and checklist are easy to administer and appear to be in the public domain.

While the diagnosis is often fairly straightforward, it does take some time, and pediatricians should feel comfortable with the idea of not trying to do everything in one visit. Instead, consider scheduling another visit or two to obtain more time to do a careful assessment. During this evaluation, a couple questions are good to keep in mind.

1. Was a diagnosis of an autistic spectrum disorder missed? OCD behaviors are extremely common among children with autistic spectrum disorders. It might be worthwhile to make sure that the developmental history (pointing, babbling, social smile, odd mannerisms) doesn’t suggest the possibility of autism.

2. Could this be a case of a PANS? There remains discussion about the possibility of an autoimmune origin to some children with OCD. The previous term of Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcus (PANDAS) has been changed to Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) to reflect a broader profile of behaviors and possible infectious triggers. While the idea remains debated in some circles, there may be value in making sure that there is not an infection lurking that should be treated.

Pearl

When querying about particular OCD symptoms, go through a list with a patient (such as provided on the CY-BOCS), and don’t rely on self-disclosure, as some symptoms, such as seeing violent or sexual images, can be quite disturbing to the child, who often won’t bring them up on his or her own.

Treatment

The recommended first-line treatment for OCD is a type of cognitive-behavioral therapy called exposure and response prevention (ERP). It is a structured form of therapy that involves patients unlearning the association that rituals are necessary in order for their fears not to be realized. While effective, the challenge is often finding a therapist with this type of training.

In many cases, it is reasonable to wait on medication treatment until after a course of ERP has been tried. For more severe cases, it is also reasonable to use both psychotherapy and medications at the same time. Some patients will say that the medication helps them do the work required in therapy.

When it comes to medications, there are a number of selective serotonin reuptake inhibitors (SSRIs) that have shown to be effective and have Food and Drug Administration approvals for pediatric OCD (for some reason that escapes me, many pharmaceutical companies have sought FDA approval for OCD and not other child psychiatric disorders). Fluoxetine, sertraline, and fluvoxamine all have FDA approval, in addition to the tricyclic clomipramine for use in refractory cases. As in all children, starting at a low dose is usually prudent (5-10 mg of fluoxetine, 12.5-25 mg of sertraline), but with OCD higher doses are often required for maximal response (more than 100 mg of sertraline or 40 mg of fluoxetine, depending on the patient’s age, size, and tolerance). It is also important to remember that the suicide warning present for the SSRIs also applies to children with anxiety disorders.

 

 

An overall treatment plan for an OCD patient, according to a previously discussed model for mental health treatment, might look like the following:

Education. Discuss diagnosis of OCD with children and family. Let them know about support organizations such as the OC Foundation.

Individual therapy. Referral to a cognitive-behavioral therapist for exposure and response prevention.

Parents. Screen parents for their own OCD or other psychopathology and refer if positive. Parental guidance regarding how best to approach the child will occur within cognitive-behavioral therapy.

School. (This is indicated if the child’s symptoms are affecting school.) Consider a request for evaluation at school to assess the need for a 504 or individualized education plan (IEP).

Environment. Discuss minimizing OCD triggers at home.

Medications. Begin fluoxetine 5 mg per day. Informed consent is important, including suicide warnings. (You might delay this step if a therapist is available to begin ERP first.)

Follow-up should take place in 2 weeks, with a possible increase of fluoxetine to 10 mg and reassessment with CY-BOCS.

When to consult? Many patients with relatively uncomplicated OCD can be effectively managed in the primary care setting. Consultation may be useful for instances of poor treatment response, other occurring psychiatric disorders (such as autism, attention-deficit/hyperactivity disorder), family conflict and resistance, or diagnostic uncertainty with other conditions, such as a psychotic disorder.

Weekend hospital admission linked to negative outcomes

Weekend hospitalization can have its pitfalls, according to a study of pediatric patients newly diagnosed with leukemia.

Patients who were admitted to the hospital over the weekend had a longer length of stay, a slightly longer wait to start chemotherapy, and a higher risk for respiratory failure than patients admitted during the week.

Elizabeth K. Goodman, of the Children’s Hospital of Philadelphia, and her colleagues reported these results in JAMA Pediatrics.

The team examined adverse clinical outcomes associated with a weekend admission for the first hospitalization of pediatric patients newly diagnosed with acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML).

The researchers used data from the Pediatric Health Information System database, which included patients admitted to 43 children’s hospitals from 1999 through 2011.

There were 10,720 patients with ALL and 1323 with AML. Roughly 17% of these patients (n=2009) were admitted to the hospital on the weekend.

Patients hospitalized on the weekend were similar to those hospitalized during the week with regard to disease type and sex. However, weekend admissions had significantly higher percentages of patients who were younger than 5 years of age, of nonwhite race/ethnicity, and publicly insured.

Patients admitted on the weekend were also more likely to be severely ill. They were significantly more likely to require ICU-level care within the first 2 days of admission (4.8% vs 3.1%, P<0.001).

An unadjusted analysis showed that inpatient mortality was similar for patients admitted to the hospital during the week and on the weekend (0.8% and 1.0%, respectively).

However, patients admitted on the weekend had a significantly longer mean hospital stay (17.8 vs 15.8 days, P<0.001) and a longer mean wait time for chemotherapy (3.9 vs 3.5 days, P<0.001).

Patients admitted on the weekend also had an increased risk of cardiovascular failure (6.4% vs 5.0%, P=0.01), respiratory failure (8.5% vs 5.7%, P<0.001), and andrenal failure (10.2% vs 8.3%, P=0.01).

However, some of these results changed when the researchers adjusted for demographic variables (disease, sex, age, race/ethnicity, and insurance), the presence of severe illness at admission, and hospital-level factors (presence of a fellowship program, Magnet status, percentage of public payers per admissions per hospital per year, and number of oncology admissions per hospital per year).

In the adjusted analysis, weekend admission remained associated with an increase in the length of hospital stay (1.4 days) and an increase in the time to chemotherapy (0.4 days).

Weekend admission also remained associated with an increased risk of respiratory failure (odds ratio, 1.5), but it was no longer associated with an increased risk of cardiovascular or renal failure.

The researchers said these findings highlight a potential area for improvement in patient care and cost reduction. Increasing weekend resources could help reduce patients’ length of stay and ensure they receive comprehensive care.

On the other hand, it might also raise hospital expenditures without decreasing negative outcomes. So additional research is needed to determine the most clinically and cost-effective combination of hospital resources to reduce the length of stay and improve outcomes for pediatric leukemia patients.

An editorial related to this study is available in JAMA Pediatrics.

FDA approves eltrombopag for SAA

The US Food and Drug Administration (FDA) has approved eltrombopag (Promacta) for use in patients with severe aplastic anemia (SAA) who have had an insufficient response to immunosuppressive therapy (IST).

Eltrombopag is an oral thrombopoietin receptor agonist that helps to induce the proliferation and differentiation of hematopoietic stem cells to increase blood cell production.

Eltrombopag is already FDA approved to treat patients with chronic immune thrombocytopenia who have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy.

The drug is also approved to treat thrombocytopenia in patients with chronic hepatitis C to allow for the initiation and maintenance of interferon-based therapy.

The latest FDA approval is based on results from an investigator-sponsored phase 2 study (09-H-0154) conducted by the National Heart, Lung and Blood Institute. Results of this trial were previously published in The New England Journal of Medicine.

Eltrombopag in SAA: Latest trial results

In this study, researchers evaluated eltrombopag in 43 SAA patients who had an insufficient response to at least 1 prior IST and a platelet count of 30 x 109/L or less.

At baseline, the median platelet count was 20 x 109/L, hemoglobin was 8.4 g/dL, the absolute neutrophil count was 0.58 x 109/L, and absolute reticulocyte count was 24.3 x 109/L.

Patients had a median age of 45 years (range, 17 to 77 years), and 56% were male. The majority of patients (84%) received at least 2 prior ISTs.

Patients received eltrombopag at an initial dose of 50 mg once daily for 2 weeks. The dose increased over 2-week periods to a maximum of 150 mg once daily.

The study’s primary endpoint was hematologic response, which was initially assessed after 12 weeks of treatment. Treatment was discontinued after 16 weeks in patients who did not exhibit a hematologic response.

Forty percent of patients (N=17) experienced a hematologic response in at least one lineage—platelets, red blood cells (RBCs), or white blood cells—after week 12.

In the extension phase of the study, 8 patients achieved a multilineage response. Four of these patients subsequently tapered off treatment and maintained the response. The median follow up was 8.1 months (range, 7.2 to 10.6 months).

Ninety-one percent of patients were platelet-transfusion-dependent at baseline. Patients who responded to eltrombopag did not require platelet transfusions for a median of 200 days (range, 8 to 1096 days).

Eighty-six percent of patients were RBC-transfusion-dependent at baseline. Patients who responded to eltrombopag did not require RBC transfusions for a median of 208 days (range, 15 to 1082 days).

The most common adverse events (≥20%) associated with eltrombopag were nausea (33%), fatigue (28%), cough (23%), diarrhea (21%), and headache (21%).

Patients also had bone marrow aspirates evaluated for cytogenetic abnormalities. Eight patients had a new cytogenetic abnormality after treatment, including 5 patients who had complex changes in chromosome 7.

Patients who develop new cytogenetic abnormalities while on eltrombopag may need to be taken off treatment.

Eltrombopag is marketed by GlaxoSmithKline under the brand name Promacta in the US and Revolade in most other countries. For more information on eltrombopag, see the prescribing information.

Forty percent of patients (N=17) experienced a hematologic response in at least one lineage—platelets, red blood cells (RBCs), or white blood cells—after week 12.

In the extension phase of the study, 8 patients achieved a multilineage response. Four of these patients subsequently tapered off treatment and maintained the response. The median follow up was 8.1 months (range, 7.2 to 10.6 months).

Ninety-one percent of patients were platelet-transfusion-dependent at baseline. Patients who responded to eltrombopag did not require platelet transfusions for a median of 200 days (range, 8 to 1096 days).

Eighty-six percent of patients were RBC-transfusion-dependent at baseline. Patients who responded to eltrombopag did not require RBC transfusions for a median of 208 days (range, 15 to 1082 days).

The most common adverse events (≥20%) associated with eltrombopag were nausea (33%), fatigue (28%), cough (23%), diarrhea (21%), and headache (21%).

Patients also had bone marrow aspirates evaluated for cytogenetic abnormalities. Eight patients had a new cytogenetic abnormality after treatment, including 5 patients who had complex changes in chromosome 7.

Patients who develop new cytogenetic abnormalities while on eltrombopag may need to be taken off treatment.

Eltrombopag is marketed by GlaxoSmithKline under the brand name Promacta in the US and Revolade in most other countries. For more information on eltrombopag, see the prescribing information.

The US Food and Drug Administration (FDA) has approved eltrombopag (Promacta) for use in patients with severe aplastic anemia (SAA) who have had an insufficient response to immunosuppressive therapy (IST).

Eltrombopag is an oral thrombopoietin receptor agonist that helps to induce the proliferation and differentiation of hematopoietic stem cells to increase blood cell production.

Eltrombopag is already FDA approved to treat patients with chronic immune thrombocytopenia who have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy.

The drug is also approved to treat thrombocytopenia in patients with chronic hepatitis C to allow for the initiation and maintenance of interferon-based therapy.

The latest FDA approval is based on results from an investigator-sponsored phase 2 study (09-H-0154) conducted by the National Heart, Lung and Blood Institute. Results of this trial were previously published in The New England Journal of Medicine.

Eltrombopag in SAA: Latest trial results

In this study, researchers evaluated eltrombopag in 43 SAA patients who had an insufficient response to at least 1 prior IST and a platelet count of 30 x 109/L or less.

At baseline, the median platelet count was 20 x 109/L, hemoglobin was 8.4 g/dL, the absolute neutrophil count was 0.58 x 109/L, and absolute reticulocyte count was 24.3 x 109/L.

Patients had a median age of 45 years (range, 17 to 77 years), and 56% were male. The majority of patients (84%) received at least 2 prior ISTs.

Patients received eltrombopag at an initial dose of 50 mg once daily for 2 weeks. The dose increased over 2-week periods to a maximum of 150 mg once daily.

The study’s primary endpoint was hematologic response, which was initially assessed after 12 weeks of treatment. Treatment was discontinued after 16 weeks in patients who did not exhibit a hematologic response.

EPO may cut risk of brain abnormalities in preterm infants

Erythropoietin (EPO) can reduce the risk of brain injury in preterm infants, a new study suggests.

Infants who received 3 doses of EPO within 42 hours of birth were less likely than their untreated peers to have abnormal scores for white matter injury, white matter signal intensity, periventricular white matter loss, and gray matter injury.

Russia Ha-Vinh Leuchter, MD, of the University Hospital of Geneva in Switzerland, and her colleagues recounted these findings in JAMA.

The researchers evaluated 495 infants who were born in Switzerland between 2005 and 2012—at 26 weeks of gestation to 31 weeks and 6 days of gestation.

The children were randomized to receive EPO (n=256) or placebo (n=239) intravenously at 3 time points: before they reached 3 hours of age, at 12 to 18 hours after birth, and at 36 to 42 hours after birth.

Due to the limited availability of MRI, the researchers were only able to assess brain injury in a nonrandomized subset of 165 infants. Seventy-seven of these children received EPO, and 88 received placebo.

The patients underwent MRI at a median gestation age of 40 weeks and 5 days (range, 35 weeks and 5 days to 44 weeks and 6 days).

“We found that the brains of the children who had received the treatment had much less damage than those in the control group,” Dr Ha-Vinh Leuchter said. “This is the first time that the beneficial effect of the EPO hormone on the brains of premature babies has been shown.”

Specifically, the results showed that, at term-equivalent age, infants treated with EPO were less likely than controls to have abnormal scores for white matter injury (22% vs 36%), white matter signal intensity (3% vs 11%), periventricular white matter loss (18% vs 33%), and gray matter injury (7% vs 19%).

These results are only the first part of this study, according to the researchers. The second—and main—part of the work will focus on the neurocognitive development of these children, who will take part in various developmental tests at 2 and 5 years of age.

“[The tests] should confirm the effect that EPO treatment has on the neurodevelopmental disabilities that very premature babies often show during their infancy,” said Petra Hüppi, MD, also of the University Hospital of Geneva.

“If this does turn out to be the case, we will have taken an important step in preventing brain damage and its long-term consequences in premature babies.”

Enrollment terminated in anticoagulant trial

Thrombus

Credit: Andre E.X. Brown

Regado Biosciences, Inc., has permanently terminated enrollment in the phase 3 REGULATE-PCI trial due to serious allergic reactions in patients treated with the Revolixys Kit (also known as REG-1).

The kit is a 2-component system consisting of pegnivacogin, an anticoagulant aptamer specifically targeting coagulation factor IXa, and its complementary oligonucleotide active control agent, anivamersen.

The REGULATE-PCI trial is a comparison of the Revolixys Kit and bivilarudin in patients undergoing percutaneous coronary intervention.

A data and safety monitoring board analyzed data from the roughly 3250 patients initially enrolled in the trial and discovered serious allergic reactions in patients treated with Revolixys.

“The [board] indicated that the level of serious allergic adverse events associated with Revolixys was of a frequency and severity such that they recommended that we do not enroll any further patients in the REGULATE-PCI trial,” said David J. Mazzo, PhD, CEO of Regado.

“We will now undertake a complete review of the unblinded database from REGULATE-PCI, which we expect will take several months to complete.”

Dr Mazzo did not provide details as to the type of allergic reactions patients experienced or the incidence of these events. He did say the exact cause of the reactions is unknown, but the data review and investigation should reveal that information.

The review should also provide information that will help Regado decide how to move forward with its development of Revolixys (REG-1) and a related system known as REG-2.

Study outlines risk factors for solid organ cancers after liver transplantation

SAN FRANCISCO – The indication for liver transplant, the selection of immunosuppression therapy, and smoking status influence the long-term risk of new solid organ malignancies after liver transplantation, Dr. Sebastian Rademacher reported at the 2014 World Transplant Congress.

Multivariate analysis showed that recipients’ risk of a new solid organ cancer was elevated for those who had a history of smoking (1.89). Risk was reduced for recipients who received tacrolimus, compared with cyclosporine A (0.56), and for patients who had primary biliary cirrhosis/primary sclerosing cholangitis (0.47) or hepatitis C infection (0.21) as the indication for transplantation.

"I think we have to reoptimize and reevaluate the currently used immunosuppressive regimens," Dr. Rademacher said. "We have to adapt cancer surveillance programs for high-risk patients. Further studies into surveillance protocols and surrogate markers and long-term outcomes are recommended."

Researchers led by Dr. Rademacher, a surgeon at the Campus Virchow Clinic, Charité, Berlin, retrospectively studied 1,179 consecutive adults who underwent liver transplantation between 1988 and 2002 and had follow-up evaluations until 2013. Patients were 47 years old, on average, at the time of transplantation, and the median follow-up was 13.3 years.

Their 20-year cumulative incidence of solid organ cancers was 14%, he reported at the congress, which was sponsored by the American Society of Transplant Surgeons. The mean age at cancer diagnosis was 56 years.

The researchers used age- and sex-matched individuals from the German general population for comparison. The standardized incidence ratio in transplant recipients was 1.2 for breast cancer, 9.4 for cancer of the oropharynx and larynx, 1.7 for cancers of the colon and rectum, 3.0 for lung cancer, 3.9 for esophageal and stomach cancers, 4.5 for kidney and bladder cancers, and 4.6 for cancers of the female genitourinary system.

"We tried to evaluate the different immunosuppressive regimens and, over time, we had, I think, 27 different primary regimens," Dr. Rademacher said. Steroid-free regimens and low-dose steroid were part of that consideration, "but we segregated them out. For the five most frequent regimens, there was no significance. We assessed immunosuppressive regimens given over at least 2 years, but there was no difference between the regimens. Also, the trough levels of tacrolimus did not have any significant influence," he said.

The investigators did not have data on cumulative immunosuppression or mTOR [mammalian target of rapamycin] inhibitors, which were introduced late in the study period, according to Dr. Rademacher, who disclosed no relevant conflicts of interest. A surrogate marker of immunosuppression, rejection frequency, did not significantly predict the development of solid organ malignancies.

The devil is in the details of this study. The incidence of solid organ tumors being high in the immunosuppressed population is well known, well documented. The difficulty is getting at what is driving that risk.

Lots of things have changed in immunosuppressive therapy over the last 20-25-years. The authors give us a snapshot, but they weren’t able to tell us whether the changes in immunosuppression had any impact on cancer risk, especially in regard to specific types of cancers.

Early elimination of cyclosporine after heart transplant has renal benefit

SAN FRANCISCO – Use of an everolimus-containing regimen with early stopping of cyclosporine after de novo heart transplantation improves renal function and reduces cardiac allograft vasculopathy, without compromising graft outcomes, new data suggest.

These was among key findings of the randomized, open-label SCHEDULE (Scandinavian Heart Transplant Everolimus De Novo Study with Early Calcineurin Inhibitor Avoidance) reported at the 2014 World Transplant Congress.

"Renal dysfunction and cardiac allograft vasculopathy are markers for increased morbidity and mortality after heart transplantation," lead author Dr. Vilborg Sigurdardottir commented when introducing the study.

Dr. Vilborg Sigurdardottir

Patients in the trial were randomized evenly to a three-drug regimen containing the calcineurin inhibitor cyclosporine (Sandimmune) or to a four-drug regimen also containing the mTOR inhibitor everolimus (Zortress) with discontinuation of cyclosporine at week 7-11. Everolimus is currently approved by the Food and Drug Administration to prevent graft rejection in kidney and liver transplant recipients and, under another brand name, to treat some cancers.

Measured glomerular filtration rate (GFR) at 12 months, the trial’s primary outcome, was 30% better in the everolimus group than in the cyclosporine group (79.8 vs. 61.5 mL/min per 1.73 m2; P less than .001), according to results presented at the congress and recently published (Am. J. Transplant. 2014;14:1828-38).

The urinary albumin-creatinine ratio was higher in the everolimus group, but none of the patients had nephrotic levels of proteinuria.

Rates of adverse events were similar, with the exception that the everolimus group had a lower rate of cytomegalovirus infection (5% vs. 30%) and a higher rate of pneumonia (12% vs. 3%), Dr. Sigurdardottir reported at the congress, which was sponsored by the American Society of Transplant Surgeons.

The incidence of biopsy-proven acute rejection of at least grade 2R was greater with everolimus (40% vs. 18%, P = .01). However, at 12 months, the groups did not differ with respect to left ventricular function as assessed by echocardiography and biomarkers, and, in a cardiac reserve substudy, with respect to cardiac output and pulmonary capillary wedge pressure.

The incidence of cardiac allograft vasculopathy, defined as a mean media-intima thickness of at least 0.5 mm on intravascular ultrasound (IVUS), was lower in the everolimus group (51% vs. 65%, P less than .01), and progression assessed as the change in percent atheroma volume was slower in that group.

"Everolimus initiation and early cyclosporine elimination in de novo heart transplant recipients showed a highly significant improvement of renal function in terms of measured GFR, a reduced incidence of cytomegalovirus [a confirmatory result of previous large-scale studies], similar numbers of adverse and serious adverse events, and an increased incidence of treated acute rejection, however, without hemodynamic compromise and with preserved cardiac function and preserved cardiac reserve," concluded Dr. Sigurdardottir, who is medical director of heart transplantation at the Transplant Institute, Sahlgrenska University Hospital, Gothenburg, Sweden. "We saw also favorable coronary remodeling and less graft vasculopathy, as previously shown."

Among patients whose donor hearts had such disease, the increase in media-intima thickness and percent atheroma volume was less with everolimus than with cyclosporine, Dr. Sigurdardottir said. "Interestingly, we saw here that the total atheroma volume decreased between baseline and 12 months in the everolimus group in the patients who had preexisting donor disease."

An attendee from Norway said, "I am a nephrologist, and if I were to get a new heart, I’d rather have a GFR of 61 and no rejection than a GFR of 73 with rejection. Have you looked at the development of donor-specific antibodies in the ones who had rejection, because I’d like to live for more than a year – I’d like to live 3 years or 5 years or 10 years."

"You are absolutely right. At the time of transplantation, we would be looking at the acute problems, and we often see the kidney dysfunction, so we want to do something about that. But of course these studies need to tell us how patients fare longer term," Dr. Sigurdardottir agreed. None of the patients were found to have donor-specific antibodies, but the trial protocol did not mandate routine measurement, she said.

An attendee from Los Angeles commented, "We tried to do CNI [calcineurin inhibitor] weaning in 2006 and had hemodynamically compromised rejection. Now, I congratulate you on being innovative and having quadruple therapy from the get-go and then taking off the CNI. But the issue of increased rejection is important because ISHLT [International Society for Heart and Lung Transplantation] data show that that does lead to poorer outcome. It is countered by your improvement in renal function, but also your IVUS result, I think, is very important as well."

 

 

"Rejection is an important issue, but it is a common issue after transplantation. It was usually manageable. Since we didn’t see any hemodynamic compromise, it was up to each investigator to evaluate what to do. There were nine patients who converted to combination therapy," Dr. Sigurdardottir reported. "The future needs to tell us what the relevance of this rejection is, and we will do a follow-up at 3 and 5 years."

Dr. Sigurdardottir disclosed no relevant conflicts of interest. The trial was sponsored by Novartis, manufacturer of everolimus.

SAN FRANCISCO – Use of an everolimus-containing regimen with early stopping of cyclosporine after de novo heart transplantation improves renal function and reduces cardiac allograft vasculopathy, without compromising graft outcomes, new data suggest.

These was among key findings of the randomized, open-label SCHEDULE (Scandinavian Heart Transplant Everolimus De Novo Study with Early Calcineurin Inhibitor Avoidance) reported at the 2014 World Transplant Congress.

"Renal dysfunction and cardiac allograft vasculopathy are markers for increased morbidity and mortality after heart transplantation," lead author Dr. Vilborg Sigurdardottir commented when introducing the study.

Dr. Vilborg Sigurdardottir

Patients in the trial were randomized evenly to a three-drug regimen containing the calcineurin inhibitor cyclosporine (Sandimmune) or to a four-drug regimen also containing the mTOR inhibitor everolimus (Zortress) with discontinuation of cyclosporine at week 7-11. Everolimus is currently approved by the Food and Drug Administration to prevent graft rejection in kidney and liver transplant recipients and, under another brand name, to treat some cancers.

Measured glomerular filtration rate (GFR) at 12 months, the trial’s primary outcome, was 30% better in the everolimus group than in the cyclosporine group (79.8 vs. 61.5 mL/min per 1.73 m2; P less than .001), according to results presented at the congress and recently published (Am. J. Transplant. 2014;14:1828-38).

The urinary albumin-creatinine ratio was higher in the everolimus group, but none of the patients had nephrotic levels of proteinuria.

Rates of adverse events were similar, with the exception that the everolimus group had a lower rate of cytomegalovirus infection (5% vs. 30%) and a higher rate of pneumonia (12% vs. 3%), Dr. Sigurdardottir reported at the congress, which was sponsored by the American Society of Transplant Surgeons.

The incidence of biopsy-proven acute rejection of at least grade 2R was greater with everolimus (40% vs. 18%, P = .01). However, at 12 months, the groups did not differ with respect to left ventricular function as assessed by echocardiography and biomarkers, and, in a cardiac reserve substudy, with respect to cardiac output and pulmonary capillary wedge pressure.

Key clinical point: For post–heart transplant patients, early cessation of cyclosporine when using an everolimus-containing regimen appears to be safe and did not compromise graft outcomes.

Major finding: Compared with patients continued on cyclosporine, patients taken off this agent at 7-11 weeks had a 30% better measured glomerular filtration rate at 12 months.

Data source: A randomized, open-label trial of 115 patients undergoing de novo heart transplantation

Disclosures: Dr. Sigurdardottir disclosed no relevant conflicts of interest. The trial was sponsored by Novartis, manufacturer of everolimus.

Multicenter study cites safety of power morcellation within an insufflated isolation bag

A 16-month multicenter study in which 73 patients underwent morcellation of the uterus or myomas within an insufflated isolation bag during minimally invasive (MI) hysterectomy or myomectomy recently has been published in Obstetrics & Gynecology. The researchers conclude that contained power morcellation using this technique is feasible.1

Sarah L. Cohen, MD, MPH, and colleagues at Fairview Ridges Hospital, Burnsville, Minnesota; Johns Hopkins Hospital, Baltimore, Maryland; Massachusetts General Hospital, Boston; and Brigham and Women’s Hospital, Boston, Massachusetts are all high-volume surgeons experienced in advanced MI gynecologic surgical techniques.1

Patients in whom morcellation was planned at the time of MI hysterectomy or myomectomy during the study period (January 2013 through April 2014) were offered in-bag morcellation and included in the study. Exclusion criteria were known or suspected malignancy. Preoperative testing was performed to evaluate risk of genital tract cancer. Perioperative information included mode of access, type of procedure(s) performed, operative time, estimated blood loss, specimen weight, intact status of isolation bag postmorcellation, length of hospital stay, intraoperative complications, postoperative complications, readmission, and reoperation.1

The technique for morcellation within an insufflated isolation bag was developed by one of the authors, Tony Shibley, MD, for use during laparoendoscopic single-site hysterectomy (WATCH Dr. Shibley’s technique video here and listen to an interview with Dr. Shibley here.) The technique adapts to multiport laparoscopic and robot-assisted laparoscopic hysterectomy and myomectomy.1

Based on the results of their study, the authors conclude: “Morcellation within an insufflated isolation bag is a feasible technique. Methods for morcellating uterine tissue in a contained manner may provide an option to minimize the risks of open power morcellation while preserving the benefits of minimally invasive surgery.”1

In response to this study, Charles R. Rardin, MD, Associate Professor of Obstetrics and Gynecology at Brown Medical School and Women and Infants’ Hospital in Providence, Rhode Island, wrote an online editorial in Obstetrics & Gynecology.2 Dr. Rardin pointed out that “Until there are more effective screening tools to detect these unusual cancers [leiomyosarcoma], surgeons and hospitals are required to develop responses to these issues.”

He suggests that one extreme reaction to the morcellation crisis is to ban any method of morcellation entirely, leaving laparotomy as the only option for tissue extraction. Finding that logic faulty—relative value to the few at greater cost to the many—he suggests that one might also question the safety of other strategies to treat leiomyomas, including ablation and embolization.

Institutions have responded in several different ways, he says:

He finds that Cohen and colleagues’ techniques lack formal investigation of bag integrity or tissue spread (as successful control of tissue spread was judged by a visual assessment by the surgeon). He also indicates that the technique described is better suited to single-port laparoscopy than multi-port, that single-site laparoscopy required additional training and skill, and that the incisions in single-site laparoscopy are fewer in number but larger in diameter, eliciting concern for increased hernia formation. The authors recognize that using the technique in multi-port surgery, because penetration of the bag by one or more trocars may cause a disruption in bag integrity, is in violation of the manufacturer’s recommendations.1,2 Dr. Rardin additionally expresses concern about “the passage of trocars through the peritoneal cavity, out of direct visualization until the trocar pierces the bag”2 where the camera resides. He is concerned about reducing one set of risks while increasing other risks, and suggests that vaginal hysterectomy would reduce the risk of dissemination while preserving the patient’s benefits from minimally invasive surgery.2

Point/Counterpoint: Is screening for asymptomatic carotid artery stenosis justified?

Point/Counterpoint: Is screening for asymptomatic carotid artery stenosis justified?

Introduction

The U.S. Preventive Services Task Force has just published its latest guidance on carotid screening for asymptomatic disease, basically stating that it should not be done (see story page 1). In this Point-Counterpoint Dr. Zierler and Dr. Berland provide their views on this controversial issue. From my perspective the debate must revolve around the following questions: The gist of the USPSTF statement seems to be that screening is being performed only to detect patients with critical carotid stenosis so that an intervention (CEA or CAS) can be performed. However, shouldn’t screening also be used to identify atherosclerotic burden in order to prevent cardiovascular morbidity? Whatever the reasons for screening, should national health systems pay for screening? If not, what about individual physicians charging for screenings on selected/nonselected patients? What about free screenings? And as Dr. Zierler and Dr. Berland suggest, is screening getting a bad rap just because screening and subsequent CEA or CAS are being poorly performed? Finally, I wouldn\'t be surprised if some of the task force members have had their own carotids screened despite their negative recommendation. We would be interested in your viewpoint, so please take our online, interactive poll on our home page (bottom right) to weigh in on this important issue.

Dr. Russell Samson is the Medical Editor of Vascular Specialist.

YES: Screen, but screen well.

By Todd Berland, M.D.

Dr. Todd Berland

Every patient with symptomatic carotid artery stenosis was asymptomatic the day before. The impact of stroke can be devastating, with a 20% mortality from the acute event and 40%-50% survival over the next 5 years. Of those surviving the initial event, a significant percentage of patients are unable to return to work, and up to 25% over the age of 65 require long-term institutional care.1 There is no doubt that the emotional, financial, and societal burden of caring for stroke patients is significant. The Asymptomatic Carotid Atherosclerosis Study and the Asymptomatic Carotid Surgery Trial demonstrated a significant reduction in stroke in asymptomatic, high-grade carotid artery stenosis patients treated with carotid endarterectomy compared to medical management alone.2,3 So wouldn’t it seem as if carotid artery screening would be beneficial?

The U.S. Preventive Services Task Force recommended against routine carotid screening because of its "high risk" and low reward. I believe that when a certified lab screens the appropriate population such as individuals over 55 with cardiovascular risk factors that include hypertension, diabetes, smoking, and hypercholesterolemia, and combines this with an intervention that has a low stroke and morbidity rate, then the balance is tipped and carotid screening becomes both low risk and high reward.

One of the problems with carotid ultrasound is that too many entrepreneurs have made a business of it. Suboptimal equipment is being used by uncertified technicians in medical offices and church parking lots all across this country. It’s no surprise that the false positives are going to be high in these situations. Also, when one combines all of the above with the screening of those who aren’t at risk, where the general prevalence of disease is low, it can be a recipe for disaster. This is going to lead to additional studies such as CT angiograms or possibly even cerebral angiograms, both of which have inherent risks.

Even though it’s possible to understand why the USPSTF may have concluded against routine screening, I believe that at-risk patients should be screened by a certified lab, and that physicians performing the interventions should be able to do so with low morbidity and mortality. Vascular surgeons have been marginalized over recent years as many others have become interested in finding and treating carotid disease. Most of us are either registered vascular technologists or registered physicians in vascular interpretation, and our labs are certified by the Intersocietal Accreditation Commission. We go through hours of continuing medical education in regard to vascular ultrasound, and our labs’ results are tested and certified for accuracy.

We need to convince insurance companies and the Centers for Medicare & Medicaid Services that these studies should be permitted only in certified labs and the results interpreted by certified physicians such as vascular surgeons.

Moreover, when indicated, the interventions should be carried out by vascular surgeons who are trained to perform both carotid endarter- ectomy and carotid artery stenting to be able to offer the patient the best individualized treatment.

To most vascular specialists, the concept of detecting asymptomatic carotid stenosis and intervening to prevent stroke makes intuitive sense, but is it consistent with the evidence? In 2007, the USPSTF concluded that the general asymptomatic adult population should not be screened for carotid stenosis, and this recommendation has been reiterated in a 2014 draft recommendation statement.1,2 Other groups, including our own Society for Vascular Surgery, have published similar recommendations.3,4

Arguments in favor of screening for asymptomatic carotid stenosis are often based on the results of randomized controlled trials such as the Asymptomatic Carotid Atherosclerosis Study, which was reported in 1995.5 However, while these trials are historically important, they are no longer clinically relevant. Surgical and catheter-based interventions for carotid atherosclerosis have evolved significantly in the last 2 decades, but the outcomes associated with modern intensive medical therapy have also improved dramatically.6,7 It is not clear that carotid endarterectomy or stenting is superior to current medical management for asymptomatic carotid stenosis, and new trials such as the recently announced CREST-2 are designed to answer these important questions.

The relatively poor reliability and accuracy of duplex ultrasound as a screening test for carotid stenosis is a major theme in the USPSTF draft recommendations, but in spite of this criticism, carotid duplex scanning has served as a clinically valuable method for classifying the severity of carotid stenosis for more than 30 years.8 As pointed out by others, the best way to ensure quality in the vascular laboratory is to recognize the importance of certified vascular sonographers, accredited vascular laboratories, and qualified medical staff. But despite high-quality ultrasound testing, relying on carotid stenosis as a marker of stroke risk has significant limitations. While there is an association between the degree of carotid stenosis and risk of stroke, many patients with severe carotid stenosis do not have strokes and some with moderate stenosis do have strokes. For example, it was reported that 61% of the symptomatic patients in the North American Symptomatic Carotid Endarterectomy Trial had less than 50% carotid stenosis.9 This suggests that stenosis severity alone does not identify those patients who are at the highest risk for stroke. Fortunately, the concept of the "vulnerable plaque" is promising as a means for more accurate risk stratification, and features such as intraplaque hemorrhage and thin or ruptured fibrous caps do correlate with a high risk for stroke.10 Experience has shown that these features can be characterized by ultrasound.11

So although screening of the general population for asymptomatic carotid stenosis is not justified, there still may be subgroups of patients with specific risk factors and plaque features that could benefit from early intervention, and future clinical trials will establish whether or not this hypothesis has merit. Until more data are available the issue of screening for asymptomatic carotid stenosis will continue to provoke debate on multiple levels. Carotid disease screening is not covered by insurance, so cost and ability to pay are key factors to consider. In these discussions, the health of the patient and the population must always be the first priority, and clinical decision-making should be evidence based.

Introduction

The U.S. Preventive Services Task Force has just published its latest guidance on carotid screening for asymptomatic disease, basically stating that it should not be done (see story page 1). In this Point-Counterpoint Dr. Zierler and Dr. Berland provide their views on this controversial issue. From my perspective the debate must revolve around the following questions: The gist of the USPSTF statement seems to be that screening is being performed only to detect patients with critical carotid stenosis so that an intervention (CEA or CAS) can be performed. However, shouldn’t screening also be used to identify atherosclerotic burden in order to prevent cardiovascular morbidity? Whatever the reasons for screening, should national health systems pay for screening? If not, what about individual physicians charging for screenings on selected/nonselected patients? What about free screenings? And as Dr. Zierler and Dr. Berland suggest, is screening getting a bad rap just because screening and subsequent CEA or CAS are being poorly performed? Finally, I wouldn\'t be surprised if some of the task force members have had their own carotids screened despite their negative recommendation. We would be interested in your viewpoint, so please take our online, interactive poll on our home page (bottom right) to weigh in on this important issue.

Every patient with symptomatic carotid artery stenosis was asymptomatic the day before. The impact of stroke can be devastating, with a 20% mortality from the acute event and 40%-50% survival over the next 5 years. Of those surviving the initial event, a significant percentage of patients are unable to return to work, and up to 25% over the age of 65 require long-term institutional care.1 There is no doubt that the emotional, financial, and societal burden of caring for stroke patients is significant. The Asymptomatic Carotid Atherosclerosis Study and the Asymptomatic Carotid Surgery Trial demonstrated a significant reduction in stroke in asymptomatic, high-grade carotid artery stenosis patients treated with carotid endarterectomy compared to medical management alone.2,3 So wouldn’t it seem as if carotid artery screening would be beneficial?

The U.S. Preventive Services Task Force recommended against routine carotid screening because of its "high risk" and low reward. I believe that when a certified lab screens the appropriate population such as individuals over 55 with cardiovascular risk factors that include hypertension, diabetes, smoking, and hypercholesterolemia, and combines this with an intervention that has a low stroke and morbidity rate, then the balance is tipped and carotid screening becomes both low risk and high reward.

One of the problems with carotid ultrasound is that too many entrepreneurs have made a business of it. Suboptimal equipment is being used by uncertified technicians in medical offices and church parking lots all across this country. It’s no surprise that the false positives are going to be high in these situations. Also, when one combines all of the above with the screening of those who aren’t at risk, where the general prevalence of disease is low, it can be a recipe for disaster. This is going to lead to additional studies such as CT angiograms or possibly even cerebral angiograms, both of which have inherent risks.

Steps to incorporate business knowledge into the medical school curriculum

Declining reimbursements, health care law changes, and increased costs means the modern physician needs to have knowledge in business, law, and medicine. In today’s health care environment business acumen is becoming a necessity few practices can survive without. A recent CNN/Money article highlighted physicians going bankrupt. Lack of a basic understanding of running a business was a common theme for failed practices in the article. Another article, written in Forbes on "Doctors Going Broke" stated that failed business models along with the overly complex coding system were factors contributing to increased bankruptcy rates among physicians. As one physician stated, "Doctors are trained in medicine but not how to run a business." In bankruptcy, everyone loses: the physician, the patients, and the employees.

The need for medically related business and managerial training for medical students and physicians is an area of education that has been frequently discussed among physicians in private and academic practice. However, little has been done by physicians or in formal programs of medical or graduate medical education to address the need to introduce this type of training. Sure there are many programs offering dual MD/MBA degrees: Harvard, Dartmouth, and the University of Texas to name a few. But, is getting an MBA really necessary? This requires a minimum of an extra year of study. Also, one must be selected into such programs, not to mention more debt incurred for the student. The MD/MBA programs do not offer positions to all medical students; they can’t, and the logistics simply aren’t feasible. Why not make business knowledge available to all medical students by making it part of the medical curriculum?

The Business and Medicine Organization (BAM) was founded at the Florida State University College of Medicine on Nov. 1, 2011. The purpose of BAM is to educate our students about the practical and financial aspects of working in the medical field in the 21st century. BAM provides speakers with topics of interest relating to the business aspects of medicine. This includes employment, starting a practice, legal aspects, contracts, investments, insurance companies, and basic economic principles. The ultimate goal of BAM is to incorporate a business course into the medical school curriculum. The vision is for this course to be an elective at first in cooperation with the Florida State College of Business. Eventually, this will be a required course.

Since its inception, BAM has grown from 4 members to almost 100 members. This year it started a yearly scholarship given to those students interested in "the business aspect of medicine." We now have a working partnership with the College of Business. The next step is incorporating business into the curriculum. Last year’s BAM President, Aarian Afshari, met with the curriculum committee to push a business elective into the curriculum. We are still actively working with the curriculum committee on this issue. Since the current member count of BAM is close to 100 members, we will exert a strong influence on the curriculum committee’s decision. Basic business knowledge is a necessity for the physician in the economic reality of health care in the 21st century.

Mr. Hayson is currently a fourth-year medical student at Florida State University, Tallahassee. His goal is to become a vascular surgeon. Before entering medical school, he worked on Wall Street for 5 years as an equities and commodities trader. He has a BS in Finance from Lehigh University, Bethlehem, Penn., and a BS in Molecular and Microbiology from the University of Central Florida, Orlando.
