Mastering the uterine manipulator: Basics and beyond

An essential but often overlooked component of a successful minimally invasive gynecologic procedure is uterine manipulation. Regardless of whether conservative or extirpative surgery is being performed, the ability to optimally position the uterus within the pelvis is critical to safe and efficient surgical dissection. The addition of a colpotomizer cup to any uterine manipulator further enhances the ability to perform a conventional or robot-assisted laparoscopic hysterectomy.

The following video, produced by my third-year resident, Katherine Palmerola, MD, and my second-year fellow, Mireille Truong, MD, aims to provide a quick reference for gynecologists to use to help teach their surgical assistants the fundamentals of assembly and use of a uterine manipulator. This video also can be used as a resource for educating residents and medical students on the essentials of uterine manipulation.

The objectives of this video are to:

 

  • outline the required instruments and steps for assembling a uterine manipulator and colpotomizer cup
  • demonstrate the technical nuances of proper uterine manipulation intraoperatively
  • highlight important clinical applications of uterine manipulation during pelvic surgery.

I hope this video proves to be a valuable resource for your practice.

Preventing, treating HBV reactivation during immunosuppressive therapy

Preventing, treating HBV reactivation during immunosuppressive therapy

Patients who are to undergo immunosuppressive therapy but are at high risk for reactivation of hepatitis B infection should receive antiviral prophylaxis, rather than being monitored for reactivation and treated only if it develops, according to a new guideline published online in Gastroenterology.

The American Gastroenterological Association conducted a rigorous review of the available evidence and compiled seven recommendations to guide clinicians and researchers in preventing HBV reactivation before patients initiate immunosuppressive therapy and in treating reactivated HBV if it arises during immunosuppressive therapy. “Despite the large number of published studies, in most cases our recommendations are weak because either (1) the quality of the available data and/or the baseline risk of HBV reactivation is low or uncertain, and/or (2) the balance of risks and benefits for a particular strategy does not overwhelmingly support its use,” said Dr. K. Rajender Reddy, lead writer of the guideline and professor of gastroenterology and hepatology at the University of Pennsylvania, Philadelphia, and his associates.

CDC/Dr. Erskine Palmer
Patients in therapy but at risk for hepatitis B reactivation should receive antiviral prophylaxis, rather than treating only if it develops.

In contrast, the data supporting the recommendation to provide prophylaxis for high-risk patients are moderately robust, so that recommendation is strong, they noted.

Patients’ level of risk is based on their HBV serologic status and the type of immunosuppression they require. For example, patients are considered at high risk for HBV reactivation if they are hepatitis B surface antigen (HBsAg) positive/anti–hepatitis B core (HBc) positive or are HBsAg negative/anti-HBc positive and are to be treated with B-cell–depleting agents such as rituximab or ofatumumab. Also at high risk are HBsAg-positive/anti-HBc–positive patients to be treated with anthracycline derivatives such as doxorubicin or epirubicin, and HBsAg-positive/anti-HBc–positive patients to be treated with moderate- or high-dose corticosteroids for 4 weeks or longer.

In these high-risk patients, antiviral prophylaxis is definitely warranted, and it should extend for at least 6 months after the immunosuppressive therapy is completed, according to the guideline. In contrast, antiviral prophylaxis is “suggested” for moderate-risk patients, but those who place a higher value on avoiding antivirals and a lower value on avoiding HBV reactivation “may reasonably select no prophylaxis over antiviral prophylaxis,” Dr. Reddy and his associates said.

In contrast, routine antiviral prophylaxis is not recommended for patients undergoing immunosuppressive therapy who are at low risk for HBV reactivation.

Other recommendations in the new guideline concern which antiviral agents are preferred in different situations. The AGA strongly recommends antivirals that have a high barrier to resistance, in preference to lamivudine, in most patients. But it acknowledges that the evidence comparing various antivirals is weak, and that the drugs vary considerably in price. “Patients who put a higher value on cost and a lower value on avoiding the potentially small risk of resistance development may reasonably select the least expensive antiviral hepatitis B medication over more expensive antiviral drugs with a higher barrier to resistance,” Dr. Reddy and his associates said (Gastroenterol. 2014 [doi:10.1053/j.gastro.2014.10.039]).

The evidence regarding patient monitoring for HBV reactivation instead of prophylaxis is so sparse that the AGA makes no recommendation for or against this strategy at present. Most studies of the issue are of poor quality, use different definitions of HBV reactivation, have inconsistent reporting of patient outcomes, and disagree about the best methods and frequency of HBV DNA monitoring. Moreover, frequent monitoring requires “considerable” personnel resources, and the methods used in clinical studies may not even be adaptable to real world practice, the investigators said.

The American Gastroenterological Association conducted a rigorous review of the available evidence and compiled seven recommendations to guide clinicians and researchers in preventing HBV reactivation before patients initiate immunosuppressive therapy and in treating reactivated HBV if it arises during immunosuppressive therapy. “Despite the large number of published studies, in most cases our recommendations are weak because either (1) the quality of the available data and/or the baseline risk of HBV reactivation is low or uncertain, and/or (2) the balance of risks and benefits for a particular strategy does not overwhelmingly support its use,” said Dr. K. Rajender Reddy, lead writer of the guideline and professor of gastroenterology and hepatology at the University of Pennsylvania, Philadelphia, and his associates.

Patients in therapy but at risk for hepatitis B reactivation should receive antiviral prophylaxis, rather than treating only if it develops.

In contrast, the data supporting the recommendation to provide prophylaxis for high-risk patients are moderately robust, so that recommendation is strong, they noted.

Patients’ level of risk is based on their HBV serologic status and the type of immunosuppression they require. For example, patients are considered at high risk for HBV reactivation if they are hepatitis B surface antigen (HBsAg) positive/anti–hepatitis B core (HBc) positive or are HBsAg negative/anti-HBc positive and are to be treated with B-cell–depleting agents such as rituximab or ofatumumab. Also at high risk are HBsAg-positive/anti-HBc–positive patients to be treated with anthracycline derivatives such as doxorubicin or epirubicin, and HBsAg-positive/anti-HBc–positive patients to be treated with moderate- or high-dose corticosteroids for 4 weeks or longer.

In these high-risk patients, antiviral prophylaxis is definitely warranted, and it should extend for at least 6 months after the immunosuppressive therapy is completed, according to the guideline. In contrast, antiviral prophylaxis is “suggested” for moderate-risk patients, but those who place a higher value on avoiding antivirals and a lower value on avoiding HBV reactivation “may reasonably select no prophylaxis over antiviral prophylaxis,” Dr. Reddy and his associates said.

In contrast, routine antiviral prophylaxis is not recommended for patients undergoing immunosuppressive therapy who are at low risk for HBV reactivation.

Other recommendations in the new guideline concern which antiviral agents are preferred in different situations. The AGA strongly recommends antivirals that have a high barrier to resistance, in preference to lamivudine, in most patients. But it acknowledges that the evidence comparing various antivirals is weak, and that the drugs vary considerably in price. “Patients who put a higher value on cost and a lower value on avoiding the potentially small risk of resistance development may reasonably select the least expensive antiviral hepatitis B medication over more expensive antiviral drugs with a higher barrier to resistance,” Dr. Reddy and his associates said (Gastroenterol. 2014 [doi:10.1053/j.gastro.2014.10.039]).

The evidence regarding patient monitoring for HBV reactivation instead of prophylaxis is so sparse that the AGA makes no recommendation for or against this strategy at present. Most studies of the issue are of poor quality, use different definitions of HBV reactivation, have inconsistent reporting of patient outcomes, and disagree about the best methods and frequency of HBV DNA monitoring. Moreover, frequent monitoring requires “considerable” personnel resources, and the methods used in clinical studies may not even be adaptable to real world practice, the investigators said.

Key clinical point: The American Gastroenterological Association published a guideline for preventing the reactivation of HBV in patients who need immunosuppressive therapy and for treating reactivated HBV when it develops in patients undergoing immunosuppression.

Major finding: Robust evidence supports the recommendation that antiviral prophylaxis is warranted in patients at high risk for HBV reactivation, “suggested” for patients at moderate risk, and not recommended for patients at low risk.

Data source: A rigorous review and summary of the available evidence regarding prevention and treatment of HBV reactivation, and a compilation of recommendations for clinicians and researchers.

Hemorrhagic Bullous Lesions Due to Bacillus cereus in a Cirrhotic Patient

To the Editor:
A 42-year-old man with hypertension, hypothyroidism, and alcohol-related cirrhosis was admitted for evaluation of rapidly deteriorating mental status. He was referred from a rehabilitation facility where he had been admitted 4 days earlier after a hospitalization for hepatorenal syndrome and pneumonia. He was alert and ambulating until the day of the current admission. On arrival he was hypotensive(54/42 mm Hg); hypothermic (35°C, rectally); and unresponsive, except to painful stimuli. Jaundice, hepatosplenomegaly, ascites, and bilateral lower extremity edema were noted. There were multiple tense and flaccid bullous lesions containing serosanguineous fluid over both tibias and calves, without crepitus (Figure 1).

Figure 1. Left tibia with multiple hemorrhagic bullae and surrounding erythema and edema. The characteristic serosanguineous drainage was seen at the lower edge of the distal bulla.
Figure 2. Computed tomography of the legs with extensive subcutaneous edema and fluid collections around the knees.
Figure 3. Computed tomography of the legs with edematous changes of the anterior compart-ment muscles.

Laboratory test results revealed leukocytosis (total leukocytes, 10,900/mm3 [reference range, 4500–10,800/mm3), hypoglycemia (glucose, <20 mg/dL [reference range, 74–106 mg/dL]), renal insufficiency (serum creatinine, 2.5 mg/dL [reference range, 0.66–1.25 mg/dL]), metabolic acidosis (pH, 7.1 [reference range, 7.35–7.45]; bicarbonate, 13 mmol/L [reference range, 22–30 mmol/L]; lactic acid, 11.9 mmol/L [reference range, 0.7–2.1 mmol/L]), liver dysfunction (aspartate aminotransferase, 576 IU/L [reference range, 15–46 IU/L]), and coagulopathy with evidence of diffuse intravascular coagulation (total platelets, 75,000/mm3 [reference range, 150,000–450,000/mm3];  international normalized ratio, 9.5 [reference range, 0.8–1.2]; partial thromboplastin time, 108 seconds [reference range 23.0–35.0 seconds]; fibrinogen, 145 mg/dL [reference range, 228–501 mg/dL]; D-dimer, >20 µg/mL [reference range, 0.01–0.58 μg/mL]). Computed tomography of the pelvis and legs showed ascites, extensive subcutaneous edema, and cutaneous blisterlike lesions superior to the level of the ankles bilaterally. No gas, foreign bodies, collections, asymmetric facial thickening, or evidence of infection across tissue planes was present (Figures 2 and 3).

Specimens of blood and aspirates from the bullae at multiple lower leg sites were sent for microbiologic evaluation. The blood specimens were inoculated at bedside into aerobic and anaerobic blood culture bottles and incubated in an automated blood culture system. The aspirate samples were inoculated to trypticase soy agar with 5% sheep blood, Columbia-nalidixic acid agar, chocolate agar, MacConkey agar, and thioglycollate broth, which were incubated at 37ºC in air supplemented with 5% CO2, and to CDC anaerobic blood agar, which was incubated under anaerobic conditions. Gram-stained smears of the aspirates from the bullae demonstrated few granulocytes and numerous large gram-positive bacilli (Figure 4). By the next day, growth of large gram-positive bacilli was detected in both aerobic and anaerobic blood culture bottles and in pure culture from all the bullae samples. The bacterial colonies on sheep blood agar were opaque and white-gray in color, with a rough surface, undulate margins, and surrounding β hemolysis. The isolate was a motile, catalase-positive, arginine-positive, salicin-positive, lecithinase-positive, and penicillin-resistant organism that was identified as Bacillus cereus.

Antimicrobial susceptibility testing for B cereus has not been standardized, but evaluation by broth microdilution suggested decreased susceptibility to penicillin (minimum inhibitory concentration [MIC], 2 µg/mL) and clindamycin (MIC, 2 µg/mL), but retained susceptibility to ciprofloxacin (MIC, ≤0.25 µg/mL), tetracycline (MIC, ≤1 µg/mL), rifampin (MIC, ≤1 µg/mL), and vancomycin (MIC, ≤2 µg/mL).

The patient was admitted to the intensive care unit and was treated initially with fluid resuscitation; transfusions; ventilatory support; and intravenous vancomycin, clindamycin, and imipenem. This regimen was changed to vancomycin and ciprofloxacin when culture and susceptibility results became available to complete a 14-day course. Signs of sepsis resolved and the mental status and skin lesions improved. Ultimately, the patient died due to complications of hepatic failure.

Bacillus cereus is a rod-shaped, gram-positive, facultative, aerobic organism that is widely distributed in the environment.1 Spore formation makes B cereus resistant to most physical and chemical disinfection methods; as a consequence, it is a frequent contaminant in materials (eg, plants, dust, soil, sediment), foodstuffs, and clinical specimens.1

Traditionally considered in the context of foodborne illness, B cereus is recognized increasingly as a cause of systemic and local infections in both immunosuppressed and immunocompetent patients. Nongastrointestinal infections reported include fulminant bacteremia, pneumonia, meningitis, brain abscesses, endophthalmitis, necrotizing fasciitis, and central line catheter–related and cutaneous infections.1,2

Figure 4. Gram-stained smears of bulla aspirate revealed large gram-positive bacilli and debris in material aspirated from a left lower leg bulla (original magnification ×100 [oil immersion]).

Cutaneous lesions may have a variety of forms and appearance at initial presentation, including small papules or vesicles that progress into a rapidly spreading cellulitis1,2 with a characteristic serosanguineous draining fluid,2 single necrotic bullae,3 and gas-gangrenelike infections with extensive soft tissue involvement resembling clostridial myonecrosis.1,4 Single or multiple papulovesicular lesions can even mimic cutaneous anthrax.1-4 Necrotic or hemorrhagic bullous lesions,3 such as those observed in our patient, are rare.

 

 

Exposed areas such as extremities and digits are most often affected, presumably due to entrance of spores from soil, water, decaying organic material, or fomites through skin microabrasions or trauma-induced wounds.1 Once in the tissue, the crystalline surface protein layer (S-layer) of the bacilli promotes adhesion to human epithelial cells and neutrophils,5 followed by release of virulence factors including proteases, collagenases, lecithinaselike enzymes, necrotizing exotoxinlike hemolysins, phospholipases, and most importantly a dermonecrotic vascular permeability factor.1,5 Toxins produced by B cereus are similar to those closely related to Bacillus anthracis, the agent of anthrax.1,2

When large gram-positive bacilli are observed in tissue or wound specimens, initial therapy should address both aerobic (Bacillus species) and anaerobic (Clostridium species) organisms.1,4,6 Once B cereus is recovered, treatment should rely on susceptibility testing of the isolate. Bacillus cereus produces ß-lactamase, thus penicillin and cephalosporin should be avoided.1 Vancomycin, clindamycin, aminoglycosides, and fluoroquinolones are the drugs of choice.1,3,4,6 Daptomycin and linezolid also are active in vitro,1 but clinical experience with these agents is limited. Necrotic infection or deep tissue involvement requires surgical intervention.

Numerous other organisms can cause cellulitis and soft tissue infections with hemorrhagic bullae.1,3,6 Streptococci, particularly Streptococcus pyogenes, and occasionally staphylococci are the primary consideration in normal hosts without trauma.3,6 In immunocompromised patients, including those with cirrhosis, diabetes mellitus, and malignancy, Clostridium perfringens and gram-negative organisms such as Escherichia coli, other enteric bacteria including Pseudomonas aeruginosa, Aeromonas, and halophilic Vibrio species are more frequent.3,6

We describe a patient with underlying cirrhosis who developed bilateral lower extremity hemorrhagic bullous lesions and sepsis due to infection with B cereus, an emerging cause of serious infections in patients with underlying immunocompromising conditions such as cirrhosis, diabetes mellitus, and malignancy. Hemorrhagic bullae in immunocompromised patients are associated with sepsis and rapidly progressive illness, and rapid treatment is essential. Bacillus cereus should be included as a consideration in the differential diagnosis and management of patients presenting with bullous cellulitis and sepsis.

Numerous other organisms can cause cellulitis and soft tissue infections with hemorrhagic bullae.1,3,6 Streptococci, particularly Streptococcus pyogenes, and occasionally staphylococci are the primary consideration in normal hosts without trauma.3,6 In immunocompromised patients, including those with cirrhosis, diabetes mellitus, and malignancy, Clostridium perfringens and gram-negative organisms such as Escherichia coli, other enteric bacteria including Pseudomonas aeruginosa, Aeromonas, and halophilic Vibrio species are more frequent.3,6

We describe a patient with underlying cirrhosis who developed bilateral lower extremity hemorrhagic bullous lesions and sepsis due to infection with B cereus, an emerging cause of serious infections in patients with underlying immunocompromising conditions such as cirrhosis, diabetes mellitus, and malignancy. Hemorrhagic bullae in immunocompromised patients are associated with sepsis and rapidly progressive illness, and rapid treatment is essential. Bacillus cereus should be included as a consideration in the differential diagnosis and management of patients presenting with bullous cellulitis and sepsis.

Polypharmacy linked to increased AFib bleeding

CHICAGO – Atrial fibrillation patients treated with an anticoagulant plus four or more other medications had significantly more bleeding complications than did those on fewer medications in a retrospective study.

“This is the first study examining polypharmacy in patients with nonvalvular atrial fibrillation,” Dr. Jonathan P. Piccini said at the American Heart Association Scientific Sessions. The main consequence is, “We should do everything we can to reduce the number of medications a patient receives,” he said.

Dr. Jonathan P. Piccini

His exploratory, retrospective analysis of data from more than 14,000 patients enrolled in an anticoagulant treatment trial showed that atrial fibrillation patients on an oral anticoagulant and taking a total of 10 or more medications concurrently had a 46% increased rate of a major bleed or clinically relevant nonmajor bleed. Patients taking five to nine medications had a 17% increased rate for this primary bleeding endpoint. Both increases were statistically significant, reported Dr. Piccini, a cardiologist at Duke University in Durham, N.C. Major bleeds alone were 90% higher in patients on at least 10 drugs and 47% higher in patients on 5-9 total drugs, compared with those on 4 or fewer, also statistically significant differences.

“Increasing medication use was associated with an increased risk of bleeding but not stroke,” he said. In addition, because the data came from a large trial that had compared the new oral anticoagulant rivaroxaban (Xarelto) with warfarin, the analysis was able to show that this polypharmacy effect was similar regardless of which anticoagulant patients took.

Polypharmacy was common among the 14,264 patients (average age, 73 years) enrolled in the trial, as 51% were on 5-9 drugs and 13% were on 10 or more drugs, with a minority of 36% forming the comparator group taking 4 or fewer medications.

The analysis used data collected from 14,264 patients enrolled in the ROCKET AF (Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared With Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation) trial, which was designed as a pivotal trial comparing the safety and efficacy of the new oral anticoagulant rivaroxaban with warfarin for stroke prevention in patients with nonvalvular atrial fibrillation (N. Engl. J. Med. 2011;365:883-91). Dr. Piccini and his associates assessed various measures of bleeding as well as strokes, vascular deaths, and all-cause deaths in the patients by their number of concomitant medications based on data collected at baseline when patients entered the trial. The relative hazard rates the investigators calculated were adjusted for all “clinically important covariates,” but Dr. Piccini acknowledged that residual confounding accounted for by the adjustments likely remained.

All-cause death was also significantly increased in patients taking at least 10 (a 43% increase) or 5-9 drugs (a 25% increase), compared with patients on 4 or fewer drugs. But the rate of stroke or nonstroke embolism was not significantly increased among patients on five or more drugs. The combined rate of stroke, nonstroke embolism, and vascular death was a statistically significant 25% higher in patients on at least 10 drugs, compared with those on 4 or fewer drugs, but there was no significant increase in patients on 5-9 drugs.

The link between higher numbers of concomitant medications and an increased bleeding rate likely has two explanations, Dr. Piccini said. It could happen because the drugs themselves promote bleeding, and because the need to prescribe multiple drugs is a marker for patients who are sicker and have more comorbidities and a higher underlying risk of bleeding.

ROCKET AF was sponsored by Janssen and Bayer. Dr. Piccini has been a consultant to and has received research funding from Janssen, Bayer, and several other companies.

The message to physicians should be to assess patients at regular intervals to make sure they really still need all their medications, and try to reduce the number whenever possible.

One of the dangers in using a new oral anticoagulant is that patients are often also taking drugs that inhibit CYP3A4 enzymes, P-glycoprotein, or both. Among patients in Dr. Piccini’s study, 19% of those on 5-9 drugs and 26% of those on 10 or more were on at least one drug that inhibited P-glycoprotein and on at least one drug that was a CYP3A4 inhibitor. The list Dr. Piccini presented of the drugs patients received that fell in this category included amiodarone, diltiazem, verapamil, and erythromycin.

Also, these patients can be on other antithrombotic or antiplatelet drugs. We regularly assess patients’ coagulation status when they are on warfarin, but not when they are on rivaroxaban or another new oral anticoagulant. If you have patients on 10 or more drugs you need to be careful, and must also determine whether they can come off any of the drugs. You need to ask yourself, “What can I stop?” This is particularly true for patients also on aspirin, a thienopyridine, or a nonsteroidal anti-inflammatory drug, which all increase bleeding risk.

Consider graded exercise before medications for postural orthostatic tachycardia syndrome

SCOTTSDALE, ARIZ. – Exercise is a cornerstone of treating postural orthostatic tachycardia syndrome, according to Dr. Deborah Tepper.

“Exercise training is really the hot new way to treat this disorder. It’s been found to be very effective,” she said at a symposium sponsored by the American Headache Society.

Postural orthostatic tachycardia syndrome (POTS) is an autonomic disorder that causes symptoms resembling panic attacks, said Dr. Tepper, who is an internist at the Cleveland Clinic Neurological Center for Pain. Patients may report syncope, dizziness, palpitations, rapid or irregular breathing, fatigue, and chest pain, she said. But to be diagnosed with POTS, they must have an increase of at least 30 beats per minute within 10 minutes of standing or with the 60-degree tilt table test. Patients aged 12-19 years must have an increase in heart rate of at least 40 beats per minute. Blood pressure may drop or stay the same, but will not fall to the extent seen in orthostatic hypotension (that is, a systolic drop of 20 mm Hg or a diastolic fall of at least 10 mm Hg), Dr. Tepper noted.

Patients should start a graded exercise program by swimming or exercising in recumbent or seated positions, said Dr. Tepper.

Deconditioning, chronic fatigue, anxiety, dehydration, and various medications increase the frequency and severity of POTS-related symptoms, Dr. Tepper said. Patients sometimes severely restrict exercise in an effort to control symptoms, but lying on the couch or going to bed “is the worst thing you can do with POTS,” she said. Instead, patients should start a graded exercise program by swimming or exercising in recumbent or seated positions. Exercise training increases the aldosterone-to-renin ratio, can reduce migraine, improves overall health and stamina, supports independent functioning, and can help restore the sleep-wake cycle.

Increasing salt and fluid intake and wearing compression socks also can improve symptoms – often to the extent that patients will not need new medications. But this conservative approach is inadequate in patients with risky occupations and is less effective when patients have frequent episodes of syncope, Dr. Tepper said.

“Beta-blockers remain an option if salts, fluids, and patient education are not enough,” she added.

Beta-blockers inhibit epinephrine release and therefore can improve the migraine and anxiety symptoms that can occur in patients with POTS, although they should not be used in patients with asthma, Dr. Tepper emphasized.

Medications such as fludrocortisone and midodrine should be reserved for patients with recurrent or resistant symptoms, according to Dr. Tepper. “Midodrine can be helpful in some people, although the evidence overall rates it as low to moderate,” she said. Midodrine is a direct vasoconstrictor and alpha-adrenergic agonist that increases vasomotor tone, but also can exacerbate headaches and may cause supine hypertension, urinary retention, and insomnia, she noted. Fludrocortisone increases plasma volume, but worsens migraine, increases fluid retention, and cannot be used in diabetic patients, she said.

Clinicians should refer patients for a cardiology evaluation if they do not improve or have risk factors such as a history of cardiac disease or a family history of sudden cardiac death, chest pain, a QRS interval of more than 120 ms, a corrected QT interval of more than 450 ms or less than 300 ms, or syncope with no warning or while lying down, Dr. Tepper said. She declared no conflicts of interest.

She declared no conflicts of interest.

Surgery duration linked to VTE risk

New research suggests that, as the duration of surgery increases, so does the risk of venous thromboembolism (VTE).

Compared with a surgical procedure of average duration, patients who underwent the longest procedures had a 1.27-fold increase in the risk of developing a VTE.

In 3 of the most common procedures—gall bladder removal, appendectomy, and gastric bypass—surgery duration was a significant, independent risk factor for VTE.

Though these results suggest an association between surgical time and VTE, the researchers said they could not confirm a causal relationship.

John Y.S. Kim, MD, of Northwestern University’s Feinberg School of Medicine in Chicago, and his colleagues reported these findings in JAMA Surgery.

The researchers analyzed data from the American College of Surgeons National Surgical Quality Improvement Program to examine the association between surgical duration and the incidence of VTE.

The study included more than 1.4 million patients who had surgery under general anesthesia at 315 US hospitals from 2005 to 2011.

A total of 13,809 patients (0.96%) had a postoperative VTE, with 10,198 (0.71%) developing deep vein thrombosis and 4772 (0.33%) developing a pulmonary embolism.

The rates of each of these events consistently increased with the duration of the surgical procedure.

The researchers divided patients into 5 quintiles representing surgery duration. In the first quintile (representing the relatively shortest procedures), there were 2033 VTEs. This was followed by 2278 in the second quintile, 2478 in the third, 2960 in the fourth, and 4060 in the fifth.

Compared with the third quintile (which served as a reference), the odds ratio (OR) for developing VTE in the first quintile was 0.86 (P<0.01). In the second quintile, the OR was 0.98 (P=0.39). The fourth and fifth quintiles had ORs of 1.10 and 1.27, respectively (P<0.001 for both).

The association between VTE incidence and the longest procedures was significant in 82% of 1000 bootstrap samples. In this analysis, there was a significant association (P<0.001) between surgery duration and VTE for gynecologic, neurologic, otolaryngologic, urologic, and vascular procedures.

In each of the 3 most common procedures, surgery duration was a significant, independent risk factor for VTE. A 1-hour increase in surgical time carried an OR of 1.18 for gall bladder removal, 1.18

for appendectomy, and 1.26 for gastric bypass (P<0.05 for all).

The researchers said these results appear to validate the widely held, but not previously substantiated, belief that longer operations are associated with a higher risk of VTE. This information could help improve VTE risk modeling, enhance thromboprophylaxis guidelines, and better inform surgical decision making.

ASH adds practices to Choosing Wisely list

Doctor consults with a family

Credit: Rhoda Baer

The American Society of Hematology (ASH) has released a second list of 5 commonly used tests, treatments, and procedures that physicians and patients should question in certain circumstances.

The additional items join an initial list of practices released last year as part of the Choosing Wisely® campaign, an initiative of the ABIM Foundation that aims to prompt conversations between patients and physicians about the necessity and potential harm of certain procedures.

These new “practices to question” are also highlighted in a manuscript published in Blood, which further describes the methods for developing the list and the evidentiary basis of the recommendations.

The new recommendations include:

  1. Don’t treat with an anticoagulant for more than 3 months in a patient with a first venous thromboembolism occurring in the setting of a major transient risk factor.
  2. Don’t routinely transfuse patients with sickle cell disease for chronic anemia or uncomplicated pain crisis without an appropriate clinical indication.
  3. Don’t perform baseline or routine surveillance CT scans in patients with asymptomatic, early stage chronic lymphocytic leukemia.
  4. Don’t test or treat for suspected heparin-induced thrombocytopenia (HIT) in patients with a low pre-test probability of HIT.
  5. Don’t treat patients with immune thrombocytopenic purpura in the absence of bleeding or a very low platelet count.

The second Choosing Wisely list was developed using a rigorous evidence-based methodology that incorporated suggestions from ASH members and prioritized avoiding harm to patients above all other considerations.

“Unnecessary treatments or tests not only add waste to the healthcare system, but, in some cases, they also expose our patients to a risk of harm,” said Lisa Hicks, MD, of St Michael’s Hospital and the University of Toronto and chair of the ASH Choosing Wisely Task Force.

“ASH developed its second Choosing Wisely list to help hematologists manage the utilization and delivery of patient-care resources, and the society encourages hematologists to consider these recommendations in all facets of their work, including patient care, teaching, innovation, and research.”

The dominant guiding principle for ASH’s list is the concept of avoiding harm. The four other established guiding principles of ASH’s involvement in the Choosing Wisely campaign are strength of evidence, aggregate cost, frequency, and making recommendations within the purview of hematology. This year, the task force added a sixth overarching principle of potential impact in the field.

“Choosing Wisely set out to stimulate conversations about waste and overuse in our healthcare system,” said Richard J. Baron, MD, President and CEO of the ABIM Foundation.

“We’ve been fortunate to be joined in this effort by many dedicated partners—including ASH—who have committed to addressing unnecessary care in their specialty. ASH’s second Choosing Wisely list gives clinicians and patients a new and important tool to help inform their conversations about what care is best for the patient.”

FDA approves first anti-CD19 drug

T cells

Credit: NIAID

The US Food and Drug Administration (FDA) has granted accelerated approval for blinatumomab (Blincyto) to treat adults with relapsed or refractory Philadelphia chromosome-negative precursor B-cell acute lymphoblastic leukemia (ALL).

Blinatumomab is a bispecific T-cell engager (BiTE®) antibody construct designed to direct the body’s T cells against target cells expressing CD19, a protein found on the surface of B cells.

Blinatumomab is the first anti-CD19 drug to receive FDA approval. It will be available as a 35 mcg single-use vial.

“Immunotherapies, especially Blincyto with its unique mechanism of action, are particularly promising for patients with leukemia,” said Richard Pazdur, MD, director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research.

“Recognizing the potential of this novel therapy, the FDA worked proactively with the sponsor under our breakthrough therapy designation program to facilitate the approval of this novel agent.”

Approval details

The FDA granted blinatumomab accelerated approval based on clinical data showing the drug has an effect on a surrogate endpoint reasonably likely to predict clinical benefit to patients.

Before granting the drug full approval, the FDA is requiring that blinatumomab’s manufacturer, Amgen, conduct a study to verify that the drug improves survival in patients with relapsed or refractory Philadelphia-negative precursor B-cell ALL.

Blinatumomab was approved with a boxed warning detailing the risk of cytokine release syndrome and neurological toxicities. The FDA also approved the drug with a Risk Evaluation and Mitigation Strategy, which consists of a communication plan to inform healthcare providers about the serious risks and the potential for preparation and administration errors.

Blinatumomab was approved more than 5 months ahead of the date the FDA was scheduled to complete review of the drug’s application (May 19, 2015).

The agency had granted blinatumomab breakthrough therapy designation, priority review, and orphan product designation because Amgen demonstrated through preliminary clinical evidence that the drug may offer a substantial improvement over available therapies.

That evidence came in the form of a phase 2 study, the results of which were presented at the 19th Congress of the European Hematology Association (EHA) in June.

Trial results

Researchers evaluated blinatumomab monotherapy in 189 patients with relapsed or refractory B-cell ALL and a median age of 39 (range, 18-79). The patients received blinatumomab by continuous intravenous infusion—4 weeks on and 2 weeks off—for up to 5 cycles.

Thirty-three percent of patients achieved a complete remission, and 9% achieved a complete remission with partial hematologic recovery. Seventy-one percent of these patients were negative for minimal residual disease.

The median relapse-free survival was 5.9 months.

Major toxicities were related to cytokine release syndrome, but cytopenias and central nervous system events were also common. The most frequent adverse events were pyrexia (59%), headache (35%), and febrile neutropenia (29%).

The most frequent grade 3 or higher adverse events were febrile neutropenia (26%), anemia (15%), and neutropenia (15%). Two percent of patients had grade 3 or higher cytokine release syndrome.

The most common grade 3 or higher nervous system events were headache (4%), encephalopathy (3%), and ataxia (2%). Three patients (2%) had grade 5 events considered treatment-related—2 with sepsis and 1 with Candida infection.
