SAN ANTONIO – Regardless of COPD patients’ bronchodilator reversibility at baseline, triple therapy with fluticasone furoate, umeclidinium, and vilanterol (FF/UMEC/VI) significantly reduced the exacerbation rate versus dual therapies, according to a recent retrospective analysis of a randomized, double-blind study.

FF/UMEC/VI, a triple-therapy combination of an inhaled corticosteroid, long-acting muscarinic antagonist, and long-acting beta2 agonist (ICS/LAMA/LABA), was superior to both LAMA/LABA and ICS/LABA combinations in reducing the rate of moderate to severe exacerbation and lung function, the analysis showed.

The ICS/LAMA/LABA combination, compared with LAMA/LABA, also significantly reduced the rate of severe exacerbations and time to first moderate to severe exacerbations in both reversible and nonreversible patients, Robert Wise, MD, FCCP, of Johns Hopkins University, Baltimore, said at the annual meeting of the American College of Chest Physicians.

The analysis was based on data from IMPACT, an international, randomized, 52-week study that included more than 10,000 patients with symptomatic COPD, of whom 18% demonstrated reversibility at screening.

“The results across both reversibility subgroups are consistent with those observed in the intention-to-treat or overall study population and show a similar benefit-to-risk profile of the triple therapy across different subtypes based on bronchodilator reversibility,” Dr. Wise told attendees in a podium presentation.

Reversibility was defined as a difference between pre- and postalbuterol assessment of FEV₁ of equal to or greater than 12% and equal to or greater than 200 mL at screening, Dr. Wise said.

Reversible patients had a 40% reduction in the rate of moderate to severe exacerbations for FF/UMEC/VI versus UMEC/VI, while nonreversible patients had a 21% reduction, according to data reported in the meeting abstract.

Severe exacerbation rates dropped by 44% and 31%, respectively, in the reversible and nonreversible patients for triple versus dual therapy, he added.

Triple therapy reduced time to first moderate to severe exacerbation versus dual therapy by 25.6% in reversible and 13.6% in nonreversible COPD patients, the data showed.

The FF/UMEC/VI combination also demonstrated improvements versus UMEC/VI in time to first severe exacerbation for both the reversible and nonreversible groups, as well as improved quality of life in both groups as measured by the St. George Respiratory Questionnaire (SGRQ) in both groups.

Results were somewhat different when comparing the FF/UMEC/VI combination with the FF/VI – the ICS/LABA combination – in this post hoc analysis.

Triple therapy did reduce moderate to severe exacerbations and improved lung function regardless of baseline reversibility. However, for the reversible patients, ICS/LAMA/LABA versus ICS/LABA did not significantly reduce risk specifically of severe exacerbations, time to first moderate to severe exacerbation, or increase odds of being an SGRQ responder, Dr. Wise said.

Nonetheless, these findings taken together imply that this ICS/LAMA/LABA combination provides clinically relevant improvements versus dual therapy across a range of important outcomes regardless of baseline reversibility, according to Dr. Wise and colleagues.

Investigators from the University of Texas Southwestern are dispelling the myth that you shouldn’t recommend intrauterine devices (IUDs) for nulliparous women because the devices might make it more difficult for them to become pregnant after discontinuation. They found that nulliparous women can just as easily get pregnant after using a progestin intrauterine system (IUS) as parous women,¹ according to results of a study presented at the American Society for Reproductive Medicine (ASRM) 2018 annual meeting (October 6–10, Denver, Colorado).

Bruce R. Carr, MD, lead investigator of the study, explained in an interview with OBG Management, “There have been a number of studies—maybe 10 to 15 years ago—that looked at pregnancy rates when patients stopped using IUDs, but most of these studies were done in women who were multiparous. There is almost no data on patients who are nulliparous stopping an IUD and trying to get pregnant.”

Participants and methods. This prospective, multicenter, clinical trial, which is still ongoing, is evaluating the efficacy and safety for up to 10 years of the Liletta levonorgestrel 52-mg IUS in nulliparous and parous women ages 16 to 45 years. Every 3 months for up to 1 year, the investigators contacted the women who discontinued the IUS during the first 5 years of use and who were trying to become pregnant to determine pregnancy status.

Outcomes. The primary outcome was time to pregnancy among nulliparous vs parous women after discontinuation of a progestin IUS.

Findings. Overall, 132 (87%) of 152 women ages 16 to 35 years at the beginning of the study who attempted to become pregnant did so within 1 year of discontinuing the IUS, and there was no difference in pregnancy rates between nulliparous and parous women (87.5% vs 86.1%, respectively; P<.82) or between nulligravid and gravid women (88.2% vs 85.7%, respectively; P<.81). High percentages of women became pregnant by the end of 3 months (43.4%) and 6 months (69.7%), with a median time to conception of 91.5 days. The women used the IUS for a median of 34 months before discontinuation. Length of IUS use and age of the women at IUS discontinuation did not affect pregnancy rates at 12 months postdiscontinuation in either nulliparous or parous women (TABLE).¹

“The bottom line,” according to Dr. Carr, is that the “pregnancy rates were the same in women who had never been pregnant compared with women who had previously been pregnant.” He continued, “People worried that if a patient who had never been pregnant used an IUD that maybe she was going to have a harder time getting pregnant after discontinuing, and now we know that is not true. It [the study] reinforces the option of using progestin IUDs and not having to worry about future pregnancy.”

SAN FRANCISCO – The University of Kentucky Medical Center, Lexington, halved the rate of MRSA and CRE infections in the ICU by switching from contact precautions to decolonization with nasal povidone iodine swabs and daily chlorhexidine wipes, according to a report presented at ID Week 2018.

M. Alexander Otto/MDedge News

The move prevented an estimated eight methicillin-resistant Staphylococcus aureus (MRSA) and three carbapenem-resistant Enterobacteriaceae (CRE) infections and saved the medical center more than $150,000 in the year following the November 2016 switch.

The goal was to address the rate of MRSA bacteremia, which was higher than national ICU averages. Contact precautions began to make less sense as MRSA became more common in the surrounding community, and “we just wanted to get rid of contact precautions,” said study lead Jason Moss, DO, an infectious disease fellow at the university.

Contact precautions are expensive, make patients feel isolated, and according to some studies, lead to worse outcomes, he said at the annual scientific meeting on infectious diseases.

Decolonization is not routine in most ICUs, but it’s gaining traction. Guidelines recommend chlorhexidine bathing with wipes to stop CRE transmission, and chlorhexidine is used to prevent central line–associated bloodstream infections (CLABSI).

A recent analysis of 17 trials found marked decreases in MRSA and CLABSI with decolonization and concluded that chlorhexidine bathing “appears to be of the most clinical benefit when infection rates are high for a given ICU population,” as was the case in Kentucky (Crit Care. 2016 Nov 23;20[1]:379).

When researchers compared the year before the change to the year after, “we were pretty surprised at how much the rates of infection and colonization decreased. There have been some people that have been doing this in the ICU, but probably not to our extent. If you want to get rid of contact precautions, this is a great process to do it with,” Dr. Moss said.

Rates of colonization with MRSA or CRE fell from about 14 isolates per 10,000 patient-days to fewer than 6 (P = .026). Infection rates fell from 3.9 isolates per 10,000 patient-days to 2 (P = .083). Combined rates of infections and colonizations fell from almost 18 isolates per 10,000 patient-days to fewer than 8 (P = .010).

Decolonization is now standard practice at the university. Every ICU patient gets a one-time povidone iodine nasal swab at admission, then daily baths with 2% chlorhexidine gluconate applied by impregnated wipe. It usually takes four or five wipes to do the entire body.

Spending on gowns fell from about $153,000 per year to just under $60,000, but spending on wipes went up from about $2,700 to $275,000, and spending on povidone iodine nasal swabs went up to more than $100,000.

When balanced against the money not spent on those 11 prevented infections, however, the program saved the medical center about $152,000 in its first year, according to Dr. Moss and his team.

There was no funding for the work, and the investigators had no disclosures.

Acute mesenteric ischemia (AMI) results when oxygen delivery to the mesenteric artery is compromised, and is a serious diagnosis that should be considered in patients of all ages to avoid significant morbidity and mortality. The majority of cases are due to arterial embolism, arterial thrombus, or intestinal hypoperfusion (non-occlusive). Acute mesenteric venous thrombosis (MVT) accounts for only 2% to 10% of AMI cases, and only 0.01% of emergency surgery admissions.¹ A large systematic review showed a 44% mortality rate for MVT, in contrast to 66% to 89% for all other forms of AMI.² The typical age range for MVT is reported between 45 and 60 years, with a slight male predominance.³ Dull, central abdominal pain is the most frequently reported symptom of MVT, although it is generally less impressive than the pain described in other forms of AMI.³Along with the hallmark of abdominal pain out of proportion to the examination, other gastrointestinal symptoms include weight loss and non-specific altered bowel function (constipation, diarrhea, abdominal distention, and bloating), which are present in half of all patients with MVT.¹ Peritoneal signs and bloody stools portend poor outcomes, as they often occur with disease progression.⁴

Case

A 26-year-old man presented to the ED with periumbilical and lower abdominal pain for 1 week. The pain was described as constant and dull, worsened by movement and oral intake, and improved with lying flat. He described bloating and decreased volume of bowel movements. He denied nausea, vomiting, fever, colicky pain, blood in stool, testicular pain, urinary complaints, trauma, or any similar episodes in the past. The patient had no known medical conditions or surgical history, except for a remote history of alcohol dependence (in remission) and tobacco use. There was no personal or family history of coagulopathy. Of note, he was seen by his primary care physician a few days prior to his ED presentation and had been instructed to take acetaminophen, which did not provide relief.

The patient’s vital signs at presentation were: blood pressure, 122/70 mm Hg; heart rate, 93 beats/min; respiratory rate, 18 breaths/min; and temperature, 37.5°C (99.5°F). Oxygen saturation was 99% on room air. The physical examination was remarkable only for mild abdominal tenderness diffusely, greater in the lower and central abdomen than in the upper abdomen. The remainder of the physical examination was unremarkable.

Laboratory studies ordered included a complete blood count, comprehensive metabolic profile, lipase, and urinalysis. The patient did have a mild transaminitis (aspartate aminotransferase, 48 U/L; alanine aminotransferase, 84 U/L); the remainder of the studies were normal. A serum lactate, drawn after the 1 L of normal saline was administered intravenously (IV), was within normal limits (0.7 mmol/L). No prior laboratory studies were available for comparison.

The patient’s continued abdominal pain and transaminitis prompted an ED bedside right upper quadrant ultrasound, which showed a small gallbladder polyp; no signs of gallbladder disease were present. The patient required three doses of morphine 4 mg IV without complete pain relief. Given the concern for pain out of proportion to physical examination, a computed tomography (CT) scan of the abdomen/pelvis with IV and oral contrast was ordered. The radiologist interpreted the scan as showing a superior mesenteric vein (SMV) thrombus extending into the splenic/portal vein confluence and the intrahepatic portal veins (Figures 1 and 2).

Discussion

Mesenteric venous thrombosis is seen predominantly in middle-aged patients presenting with vague symptoms, which makes this a challenging diagnosis to make in the acute care setting. Risk factors for MVT include recent injury (causing trauma to the vasculature), recent surgery (causing stagnant blood flow), inflammatory conditions, and hypercoagulable states.¹ In this patient’s case, no risk factors were identified; although the majority of cases of MVT will have an identifiable risk factor.² Still, 21% to 49% of cases of MVT are considered idiopathic.^1,3It is possible that our patient had a prior undiagnosed pancreatitis associated with his history of alcoholism that contributed to his thrombosis. Pancreatitis and other inflammatory conditions, including diverticulitis or inflammatory bowel disease, are more commonly associated with thrombus formation in the large veins, as opposed to an undiagnosed hypercoagulable state, which would more likely affect distal venuoles, vasa recta, or venous arcades.^1,5 The patient’s mild transaminitis was likely secondary to hepatic congestion from the venous thrombus extending to the splenic-portal vein confluence and intrahepatic portal vein. One study looked at patients with pancreatitis and found that 16.7% of their study population had an SMV thrombus, while 4.1% had a SMV thrombus with a concomitant portal vein thrombus.⁶

Although there are no pathognomonic laboratory findings of MVT, elevated lactate, leukocytosis, and elevated D-dimer levels may be helpful in supporting the diagnosis.^7,8 A recent study found that elevated D-dimer levels may be a specific marker in the early recognition of acute SMV thrombosis, as well as predicting risk, outcomes, and treatment options.⁸ However, emergency physicians should maintain a high index of suspicion in patients with concerning features of the disease, since normal laboratory values, including lactate, do not reliably exclude the diagnosis.

Computed tomography scanning and CT angiography (CTA) are quite helpful in diagnosing MVT. Ultrasound of the upper abdomen may also play a role, noting dilated or thickened bowel wall with intraluminal air or echogenic material in the superior mesenteric vein or portal vein.⁹ Although magnetic resonance venography most reliably demonstrates thrombi, its lack of widespread availability makes CT with IV contrast the preferred initial study.³Computed tomography not only has high sensitivity, but also offers alternative diagnoses in the undifferentiated presentation.¹One study found CT to be 100% sensitive in detecting any abnormality associated with MVT or bowel ischemia.¹⁰ Common CT findings of MVT include dilated and thickened bowel loops, mesenteric fat standing, ascites, a halo or target appearance of bowel, vessel filling defects from a thrombus, and pneumatosis intestinalis.¹¹ The latter usually indicates transmural infarction, and can extend as portomesenteric vein gas.¹¹ Of note, if the initial CT scan is non-diagnostic and a high clinical suspicion for mesenteric ischemia remains with no alternative diagnosis, CTA is the gold standard.^3,7Expeditious diagnosis of MVT is imperative, given the potential complications of intestinal infarction, submucosal hemorrhage secondary to edema, and third spacing of the venous outflow into the bowel wall due to collateral vessels being unable to redirect blood flow in conjunction with complete venous occlusion.¹²Not all MVTs progress to infarction, given the extensive collateral circulation. Early diagnosis, however, is crucial for conservative management to be effective.⁹Acute MVT without signs of infarction necessitates anticoagulation therapy to decrease clot propagation and recurrence.¹ In addition, prophylactic antibiotics to limit bacterial translocation, and bowel rest are advised.^13,14 If the patient is unresponsive to anticoagulation, thrombolytic and endovascular therapies may be of benefit in select patients.¹⁵ Once intestinal ischemia or infarction develops, the prognosis is poor: mortality approaches 75% with infarction.¹ If signs of bowel infarction are present, a laparotomy must be performed promptly, although in most cases, delayed patient presentation makes small bowel resection unavoidable.⁹ Further testing for hypercoagulability is recommended, particularly in isolated thrombosis, since long-term anticoagulation therapy may be necessary if a coagulopathy is discovered.¹

Conclusion

Mesenteric venous thrombosis is atypical in a young, healthy patient. However, due to high mortality rates with disease progression, it is important to consider in any patient with unrelenting abdominal pain and vague gastrointestinal symptoms of uncertain cause, even in those without risk factors. Early detection and management of MVT before progression to mesenteric ischemia and infarction considerably lowers the mortality rate. Emergency physicians must be vigilant when treating a patient with abdominal pain out of proportion to physical examination, unrelenting pain despite analgesic medications, or repeat ED visits for the same abdominal complaints.

Acute mesenteric ischemia (AMI) results when oxygen delivery to the mesenteric artery is compromised, and is a serious diagnosis that should be considered in patients of all ages to avoid significant morbidity and mortality. The majority of cases are due to arterial embolism, arterial thrombus, or intestinal hypoperfusion (non-occlusive). Acute mesenteric venous thrombosis (MVT) accounts for only 2% to 10% of AMI cases, and only 0.01% of emergency surgery admissions.¹ A large systematic review showed a 44% mortality rate for MVT, in contrast to 66% to 89% for all other forms of AMI.² The typical age range for MVT is reported between 45 and 60 years, with a slight male predominance.³ Dull, central abdominal pain is the most frequently reported symptom of MVT, although it is generally less impressive than the pain described in other forms of AMI.³Along with the hallmark of abdominal pain out of proportion to the examination, other gastrointestinal symptoms include weight loss and non-specific altered bowel function (constipation, diarrhea, abdominal distention, and bloating), which are present in half of all patients with MVT.¹ Peritoneal signs and bloody stools portend poor outcomes, as they often occur with disease progression.⁴

Case

A 26-year-old man presented to the ED with periumbilical and lower abdominal pain for 1 week. The pain was described as constant and dull, worsened by movement and oral intake, and improved with lying flat. He described bloating and decreased volume of bowel movements. He denied nausea, vomiting, fever, colicky pain, blood in stool, testicular pain, urinary complaints, trauma, or any similar episodes in the past. The patient had no known medical conditions or surgical history, except for a remote history of alcohol dependence (in remission) and tobacco use. There was no personal or family history of coagulopathy. Of note, he was seen by his primary care physician a few days prior to his ED presentation and had been instructed to take acetaminophen, which did not provide relief.

The patient’s vital signs at presentation were: blood pressure, 122/70 mm Hg; heart rate, 93 beats/min; respiratory rate, 18 breaths/min; and temperature, 37.5°C (99.5°F). Oxygen saturation was 99% on room air. The physical examination was remarkable only for mild abdominal tenderness diffusely, greater in the lower and central abdomen than in the upper abdomen. The remainder of the physical examination was unremarkable.

Laboratory studies ordered included a complete blood count, comprehensive metabolic profile, lipase, and urinalysis. The patient did have a mild transaminitis (aspartate aminotransferase, 48 U/L; alanine aminotransferase, 84 U/L); the remainder of the studies were normal. A serum lactate, drawn after the 1 L of normal saline was administered intravenously (IV), was within normal limits (0.7 mmol/L). No prior laboratory studies were available for comparison.

The patient’s continued abdominal pain and transaminitis prompted an ED bedside right upper quadrant ultrasound, which showed a small gallbladder polyp; no signs of gallbladder disease were present. The patient required three doses of morphine 4 mg IV without complete pain relief. Given the concern for pain out of proportion to physical examination, a computed tomography (CT) scan of the abdomen/pelvis with IV and oral contrast was ordered. The radiologist interpreted the scan as showing a superior mesenteric vein (SMV) thrombus extending into the splenic/portal vein confluence and the intrahepatic portal veins (Figures 1 and 2).

Crizanlizumab effectively reduced vaso-occlusive crises among patients with sickle cell disease (SCD) who have numerous crises, exhibit the HbSS genotype, and take concomitant hydroxyurea, according to investigators.

CDC/Janice Haney Carr

Across subgroups, crizanlizumab was safe and more effective than placebo at delaying time to first vaso-occlusive crisis (VOC) and eliminating crises, reported lead author Abdullah Kutlar, MD, of the Sickle Cell Center at the Medical College of Georgia, Augusta, and his colleagues.

The phase 2 SUSTAIN trial recently showed that crizanlizumab – a humanized, anti–P-selectin monoclonal antibody – reduced the frequency of VOCs by 45% and delayed time to first crisis by about 3 months (N Engl J Med. 2017;376:429-39).

Additionally, a subgroup analysis showed that there was a lower frequency of pain crises with crizanlizumab 5 mg/kg, compared with placebo, regardless of the number of prior VOCs, concomitant hydroxyurea use, or the SCD genotype.

The present post hoc analysis took a deeper look at these observations across the same subgroups; specifically, the investigators assessed elimination of VOCs, time to first crisis, and adverse events. They reported the findings in the American Journal of Hematology.

Crizanlizumab eliminated pain crises about seven times more frequently than did placebo in patients who had a high frequency of VOCs before the study (28.0% vs. 4.2%), and about twice as often in patients with the HbSS genotype (31.9% vs. 17.0%), and patients who were using concomitant hydroxyurea (33.3% vs. 17.5%).

Further analysis showed that crizanlizumab delayed time to first pain crisis across all subgroups, most dramatically in patients with the HbSS genotype (4.07 months for crizanlizumab vs. 1.12 months for placebo). Safety was comparable across subgroups.

“These findings provide supportive evidence that crizanlizumab provides a clinically meaningful treatment benefit when used alone or in combination with hydroxyurea for the prevention of VOCs,” the investigators wrote.

An ongoing phase 2 pharmacokinetic/pharmacodynamic study is evaluating a higher dose of crizanlizumab (7.5 mg/kg), and another trial seeks to evaluate pediatric doses of the drug.

The study was sponsored by Novartis. The authors reported financial relationships with Novartis, Bluebird Bio, AstraZeneca, and others.

DUBROVNIK, CROATIA – An updated scoring system can more accurately identify lymphoma patients who may require thromboprophylaxis, according to researchers.

The revised scoring system, ThroLy, proved more effective than other systems for predicting thromboembolic events in lymphoma patients, with a positive predictive value of 22%-25%, a negative predictive value of 96%, sensitivity of 56%-57%, and specificity of 85%-87%.

Darko Antic, MD, PhD, of the University of Belgrade in Serbia, presented these findings at Leukemia and Lymphoma, a meeting jointly sponsored by the University of Texas MD Anderson Cancer Center and the School of Medicine at the University of Zagreb, Croatia.

Dr. Antic said that he and his colleagues developed ThroLy because other systems used to predict venous thromboembolism (VTE) are not quite right for lymphoma. He noted that the Padua score is not designed for cancer patients and the Khorana score is predominantly used for solid tumor malignancies.

The ThroLy scoring system is based on variables used in the Padua and Khorana systems, as well as variables that are specific to lymphoma patients.

In a previous study, the researchers found several variables that were independently associated with risk for VTE in lymphoma, including previous VTE, previous acute MI or stroke, mediastinal involvement, high body mass index, reduced mobility, extranodal localization, neutropenia, and hemoglobin less than 100 g/L (Am J Hematol. 2016 Oct;91[10]:1014-9).

In an initial version of the ThroLy scoring system, previous VTE, previous acute MI/stroke, obesity, and mediastinal involvement were all worth two points, and the other factors were worth a single point in the ThroLy system.

Patients with scores of 0 to 1 were considered low risk, patients with scores of 2 to 3 were considered intermediate risk, and patients with scores of 4 or greater were considered high risk.

To validate and refine ThroLy, Dr. Antic and his colleagues used it to assess 1,723 lymphoma patients treated at eight institutions in Austria, Croatia, France, Jordan, Macedonia, Spain, Switzerland, and the United States.

Patients had indolent non-Hodgkin lymphoma, aggressive non-Hodgkin lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, and Hodgkin lymphoma. Most subjects (84%) were outpatients. A total of 9%of patients had thrombosis, with 7% having VTE.

ThroLy had a positive predictive value of 17%, compared with 11% with Khorana and 13% with Padua. The negative predictive value was 93%, 92%, and 95%, respectively. The sensitivity was 51% with ThroLy, 42% with Khorana, and 70% with Padua; specificity was 72%, 64%, and 52%, respectively.

“The positive predictive value was low [with ThroLy] but definitely higher than the positive predictive value of the other two [scoring systems],” Dr. Antic noted.

Updated models

To further improve ThroLy, the researchers updated the system, creating two new models. Model 1 included the type of lymphoma/clinical stage (1 point), previous VTE (5 points), reduced mobility (2 points), hemoglobin less than 100 g/L (1 point), and the presence of vascular devices (1 point). Model 2 included all of the variables in Model 1 plus the thrombophilic condition, which was worth 1 point.

Patients were considered low risk if they scored 2 points or lower and high risk if they scored more than 2 points.

For Model 1, the positive predictive value was 22%, the negative predictive value was 96%, the sensitivity was 56%, and the specificity was 85%. For Model 2, the positive predictive value was 25%, the negative predictive value was 96%, the sensitivity was 57%, and the specificity was 87%.

There were no major differences in model discrimination and calibration based on the country in which a patient was treated or whether the patient was treated in an inpatient or outpatient setting.

Dr. Antic did not report any conflicts of interest. The Leukemia and Lymphoma meeting is organized by Jonathan Wood & Association, which is owned by the parent company of this news organization.

For Model 1, the positive predictive value was 22%, the negative predictive value was 96%, the sensitivity was 56%, and the specificity was 85%. For Model 2, the positive predictive value was 25%, the negative predictive value was 96%, the sensitivity was 57%, and the specificity was 87%.

There were no major differences in model discrimination and calibration based on the country in which a patient was treated or whether the patient was treated in an inpatient or outpatient setting.

DUBROVNIK, CROATIA – An updated scoring system can more accurately identify lymphoma patients who may require thromboprophylaxis, according to researchers.

The revised scoring system, ThroLy, proved more effective than other systems for predicting thromboembolic events in lymphoma patients, with a positive predictive value of 22%-25%, a negative predictive value of 96%, sensitivity of 56%-57%, and specificity of 85%-87%.

Darko Antic, MD, PhD, of the University of Belgrade in Serbia, presented these findings at Leukemia and Lymphoma, a meeting jointly sponsored by the University of Texas MD Anderson Cancer Center and the School of Medicine at the University of Zagreb, Croatia.

Dr. Antic said that he and his colleagues developed ThroLy because other systems used to predict venous thromboembolism (VTE) are not quite right for lymphoma. He noted that the Padua score is not designed for cancer patients and the Khorana score is predominantly used for solid tumor malignancies.

The ThroLy scoring system is based on variables used in the Padua and Khorana systems, as well as variables that are specific to lymphoma patients.

In a previous study, the researchers found several variables that were independently associated with risk for VTE in lymphoma, including previous VTE, previous acute MI or stroke, mediastinal involvement, high body mass index, reduced mobility, extranodal localization, neutropenia, and hemoglobin less than 100 g/L (Am J Hematol. 2016 Oct;91[10]:1014-9).

In an initial version of the ThroLy scoring system, previous VTE, previous acute MI/stroke, obesity, and mediastinal involvement were all worth two points, and the other factors were worth a single point in the ThroLy system.

Patients with scores of 0 to 1 were considered low risk, patients with scores of 2 to 3 were considered intermediate risk, and patients with scores of 4 or greater were considered high risk.

To validate and refine ThroLy, Dr. Antic and his colleagues used it to assess 1,723 lymphoma patients treated at eight institutions in Austria, Croatia, France, Jordan, Macedonia, Spain, Switzerland, and the United States.

Patients had indolent non-Hodgkin lymphoma, aggressive non-Hodgkin lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, and Hodgkin lymphoma. Most subjects (84%) were outpatients. A total of 9%of patients had thrombosis, with 7% having VTE.

ThroLy had a positive predictive value of 17%, compared with 11% with Khorana and 13% with Padua. The negative predictive value was 93%, 92%, and 95%, respectively. The sensitivity was 51% with ThroLy, 42% with Khorana, and 70% with Padua; specificity was 72%, 64%, and 52%, respectively.

“The positive predictive value was low [with ThroLy] but definitely higher than the positive predictive value of the other two [scoring systems],” Dr. Antic noted.

Updated models

To further improve ThroLy, the researchers updated the system, creating two new models. Model 1 included the type of lymphoma/clinical stage (1 point), previous VTE (5 points), reduced mobility (2 points), hemoglobin less than 100 g/L (1 point), and the presence of vascular devices (1 point). Model 2 included all of the variables in Model 1 plus the thrombophilic condition, which was worth 1 point.

Patients were considered low risk if they scored 2 points or lower and high risk if they scored more than 2 points.

For Model 1, the positive predictive value was 22%, the negative predictive value was 96%, the sensitivity was 56%, and the specificity was 85%. For Model 2, the positive predictive value was 25%, the negative predictive value was 96%, the sensitivity was 57%, and the specificity was 87%.

There were no major differences in model discrimination and calibration based on the country in which a patient was treated or whether the patient was treated in an inpatient or outpatient setting.

PHILADELPHIA – Black patients are more likely to be put on a transplant list because of acute liver failure, be listed as status 1, and receive a liver transplant, compared with white patients, according to a recent presentation at the annual meeting of the American College of Gastroenterology.

Jeff Craven/MDedge News

Lauren D. Nephew, MD, MSCE, of Indiana University in Indianapolis, and her colleagues performed a retrospective cohort study of black and white patients with a minimum age of 18 years in the United Network of Organ Sharing database who were wait-listed for a liver transplantation during 2002-2016. They examined patient clinical characteristics, acute liver failure (ALF) etiologies, wait-list status, and posttransplant survival outcomes through Kaplan Meier analysis.

“We really wanted to explore this topic in patients with acute liver failure, some of the sickest patients that we see,” Dr. Nephew said in her presentation. “We wanted to really determine whether or not there were differences in clinical characteristics and etiologies of acute liver failure in patients by race who are listed for liver transplantation.”

“Then, we wanted to compare wait-list outcomes,” she added, such as “differences by race in liver transplantation or wait-list removal because of death or becoming too sick for transplant.”

There were 11,289 patients in the white ALF group and 2,112 patients in the black ALF group; 2,876 (25.5%) of patients in the white ALF and 790 (37.4%) in the black ALF group were listed as status 1, which indicated an expected survival of 7 days or less. There were similar clinical characteristics for the white and black ALF status 1 patients regarding age (34.2 years vs. 36.3 years), Model for End-Stage Liver Disease (MELD) score (34 vs. 36; P less than .001), international normalized ratio (INR) test (mean 4.5 vs. mean 5.0; P = .001), creatinine levels (2.1 mg/dL vs. 1.9 mg/dL; P less than .001), and percentage of patients who were hepatic encephalopathy grade 3 or 4 (60.0% vs. 63.2%; P = .10). However, Dr. Nephew noted significantly higher bilirubin levels in the black ALF status 1 cohort (17.9 mg/dL), compared with the white ALF status 1 cohort (11.3 mg/dL; P less than .001).

The causes for ALF in each group included drug-induced liver failure (white status 1 cohort, 34.1%; black status 1 cohort, 20.6%), autoimmune hepatitis (2.7% vs. 9.4%), Wilson’s disease (0.58% vs. 0.13%), unknown etiology (34.5% vs. 42.5%), and other etiology (22.9% vs. 17%). For patients who underwent liver transplant and wait-list removal, there were no significant differences in wait-list removal “despite black patients being sicker at presentation,” Dr. Nephew said. Black patients were more likely to be listed to status 1 and transplanted at 62% (490 patients), compared with white patients at 53% (1,524 patients). There were 713 white patients (24.8%) removed from the transplant list, compared with 114 (13.8%) of black patients.

“If you are transplanted and you don’t die, then you are likely removed from the list for other reasons, and the most common reason is that you improved and became well, and so white patients were significantly more likely to be removed from the wait-list because of improvement, compared with black patients,” Dr. Nephew said.

In a competing risk analysis, the researchers found the hazard ratio for white patients who were status 1 and removed from the wait-list because of death or becoming too sick was 1.04 (95% confidence interval, 0.89-1.21) and those white patients who were listed as status 1 and then transplanted was 1.2 (95% CI, 1.08-1.30). In a multivariate analysis, the hazard ratio for white patients who were listed as status 1 and transplanted, which contained bilirubin at transplant, was 1.08 (95% CI, 0.98-1.19). Kaplan Meier 1-year survival post-transplant was 82.8% in white patients and 79.6% in black patients (P = .09).

“I think the question that we’ve been asking ourselves is, is this because black patients are presenting later with their acute liver disease and are sicker at presentation, or do they just have worse liver disease inherently on presentation that drove these findings?” Dr. Nephew said.

Dr. Nephew reports no relevant conflicts of interest.

SAN ANTONIO – It may not always be necessary to tell parents of children with asthma to get rid of the household pet, a recent study suggests.

Andrew D. Bowser/MDedge News

Children with uncontrolled asthma who were provided with guideline-appropriate care had significant improvements in a variety of asthma measures, regardless of whether parents reported pets or smoking at home, according to results of the 4-year, 471-patient prospective study.

Those results suggest that clinicians should be working to make sure the guidelines are being closely followed before, for example, telling parents they need to consider getting rid of the family pet, said Shahid Sheikh, MD, FCCP, of Nationwide Children’s Hospital, Columbus, Ohio.

“As the guidelines still work, we need to focus and develop the connections with the family to make sure the patients are on the right treatment, and that they’re getting the medications,” Dr. Sheikh said in an interview at the annual meeting of the American College of Chest Physicians.

The prospective cohort study by Dr. Sheikh and his colleagues, presented in a poster session, included children referred to a pediatric asthma center with the diagnosis of uncontrolled asthma. All patients received asthma care according to National Asthma Education and Prevention Program Expert Panel Report 3 guidelines.

Medications were changed as needed, and the asthma action plan was revised accordingly and reviewed with the family at each visit, Dr. Sheikh reported. After a baseline evaluation, clinic visits for the study occurred at 3 months, 6 months, and then at 1, 2, 3, and 4 years.

Out of 471 patients, 258 had pets, and 125 were in homes where smoking took place, according to parent reports.

Asthma control test scores were 15.1 at baseline for children in no-pet households, and 16.5 for those with pets; by the 3-month visit, scores increased to 20.1 and 20.3 for the no-pet and pet groups, and at 4 years, those scores had edged up to 22.2 and 22.7 (P = .371), Dr. Sheikh reported.

Similarly, after care was started, there was no significant difference between the no-pet and pet groups in mean percent of predicted forced expiratory volume in 1 second (FEV₁₎, wheezing, nighttime cough, albuterol use, and other factors over the 4 years of follow-up, he said.

Likewise, looking at the data by nonsmoking vs. smoking households, asthma control test scores at baseline were 16.1 and 15.1, respectively, and at 4 years they were 22.2 and 22.3 (P = .078), with a similar lack of difference in predicted FEV₁, wheezing, and all other factors evaluated.

Getting rid of the family pet may need to be a consideration for some families, but based on these data, that might not be necessary for the majority of families, Dr. Sheikh said in the interview.

“On the other hand, we are not saying that if you are smoking, you should continue to smoke,” he added.

“What we are saying is that smoking is bad, but if your child is not getting better, I don’t want to blame your smoking for it. There may be something else which may be more important than smoking which we are missing – the child may not be getting the medicine, or may not be on the right medicine, or may have other comorbidities.”

Dr. Sheikh and his coinvestigators disclosed that they had no relationships relevant to the study.

BERLIN – Depression and bipolar disorder are major risk factors for worsening disability in people with multiple sclerosis, according to the results of a large Swedish registry-based study.

Sara Freeman/MDedge News

The presence of depression increased the risk of having a sustained Expanded Disability Status Scale (EDSS) score of 3.0 by 54% and 4.0 by 87%, and it doubled the risk of an EDSS of 6.0.

Selective serotonin reuptake inhibitor treatment also upped the risk of greater disability, with patients exposed to SSRIs having a 40% increased risk of a sustained EDSS of 3.0, a 97% chance of having a sustained EDSS of 4.0, and 2.2-fold increased risk of a sustained EDSS of 6.0.

“We know that mood disorders are highly prevalent in people with multiple sclerosis,” Stefanie Binzer, MD, said at the annual congress of the European Committee for Treatment and Research in Multiple Sclerosis. She gave her presentation at the meeting on Oct. 10, which was World Mental Health Day.

The presence of mood disorders is associated with reduced quality of life, said Dr. Binzer of the department of clinical neuroscience at the Karolinska Institute in Stockholm. Furthermore, depression is the major risk factor for suicidality in patients with MS. However, before this study the effect of having a comorbid mood disorder on MS patients’ disability levels had not been established.

The investigators analyzed data from 5,875 patients in the Swedish MS registry between 2001 and 2014. By matching these patients to records in the Swedish National Patient Registry and the Swedish National Prescribed Drug Registry, they found that 8.5% (n = 502) had an International Classification of Diseases, 10th revision (ICD-10), code for depression. Of these, 261 had received a diagnosis of depression before their diagnosis of MS.

Of 3,817 patients with MS onset between 2005 and 2014, 27.4% (n = 1,048) had collected at least one prescription for an SSRI.

“What we found was that MS patients with either an ICD code for depression or having been exposed to SSRIs had a significantly increased risk of reaching EDSS 3.0,” Dr. Binzer reported. The age at which patients reached these milestones were younger in both groups when compared with MS patients without depression, she observed.

“The difference between the groups [MS with and MS without depression] seemed to increased with EDSS,” Dr. Binzer said.

Although not statistically significant, there was a trend for patients with depression to be more likely to convert to secondary progressive MS, with a hazard ratio of 1.38 (95% confidence interval, 0.91-2.1).

“For a sensitivity analysis, we found that those who had depression prior to their first MS symptom, the median age when they reached EDSS 3.0 and 4.0 was reduced by 3 and 7 years, respectively,” Dr. Binzer said, adding that, unfortunately, there wasn’t enough power to look at the other endpoints.

In regard to bipolar disorder, 1.5% (n = 200) of 13,125 MS patients diagnosed between 1973 and 2014 were identified with this mood disorder. Its presence significantly increased the risk of MS patients reaching an EDSS score of 4.0 by 58% (95% CI, 1.1-2.28), but not EDSS 3.0 (HR = 1.34; 95% CI, 0.94-1.92) or 6.0 (HR = 1.16; 95% CI, 0.79-1.69). The latter could be due to smaller sample size, Dr. Binzer suggested.

The investigators’ analysis of the results stratified by sex, conducted because men tend to fare worse than women with MS and progress faster, showed that for both depression and bipolar disorder, men were at significantly higher risk of reaching sustained disability milestones. Indeed, compared with women, men with depression had a 61% increased risk and those with bipolar disorder a 31% increased risk of reaching an EDSS score of 6.0. They also had 51% and 32% increased risks of conversion to secondary progressive MS.

“We don’t know the mechanisms that underlie these associations,” Dr. Binzer noted. “Irrespective of the underlying mechanisms, [the study] clearly shows that it’s imperative that we recognize, early, mood disorders in MS patients, and manage them effectively in order to provide better care and hopefully reduce MS disability worsening.”

The research was funded by the Swedish Research Council and the Swedish Brain Foundation. Dr. Binzer has received speaker fees and travel grants from Biogen.

The presence of depression increased the risk of having a sustained Expanded Disability Status Scale (EDSS) score of 3.0 by 54% and 4.0 by 87%, and it doubled the risk of an EDSS of 6.0.

Selective serotonin reuptake inhibitor treatment also upped the risk of greater disability, with patients exposed to SSRIs having a 40% increased risk of a sustained EDSS of 3.0, a 97% chance of having a sustained EDSS of 4.0, and 2.2-fold increased risk of a sustained EDSS of 6.0.

“We know that mood disorders are highly prevalent in people with multiple sclerosis,” Stefanie Binzer, MD, said at the annual congress of the European Committee for Treatment and Research in Multiple Sclerosis. She gave her presentation at the meeting on Oct. 10, which was World Mental Health Day.

The presence of mood disorders is associated with reduced quality of life, said Dr. Binzer of the department of clinical neuroscience at the Karolinska Institute in Stockholm. Furthermore, depression is the major risk factor for suicidality in patients with MS. However, before this study the effect of having a comorbid mood disorder on MS patients’ disability levels had not been established.

The investigators analyzed data from 5,875 patients in the Swedish MS registry between 2001 and 2014. By matching these patients to records in the Swedish National Patient Registry and the Swedish National Prescribed Drug Registry, they found that 8.5% (n = 502) had an International Classification of Diseases, 10th revision (ICD-10), code for depression. Of these, 261 had received a diagnosis of depression before their diagnosis of MS.

Of 3,817 patients with MS onset between 2005 and 2014, 27.4% (n = 1,048) had collected at least one prescription for an SSRI.

“What we found was that MS patients with either an ICD code for depression or having been exposed to SSRIs had a significantly increased risk of reaching EDSS 3.0,” Dr. Binzer reported. The age at which patients reached these milestones were younger in both groups when compared with MS patients without depression, she observed.

“The difference between the groups [MS with and MS without depression] seemed to increased with EDSS,” Dr. Binzer said.

Although not statistically significant, there was a trend for patients with depression to be more likely to convert to secondary progressive MS, with a hazard ratio of 1.38 (95% confidence interval, 0.91-2.1).

“For a sensitivity analysis, we found that those who had depression prior to their first MS symptom, the median age when they reached EDSS 3.0 and 4.0 was reduced by 3 and 7 years, respectively,” Dr. Binzer said, adding that, unfortunately, there wasn’t enough power to look at the other endpoints.

In regard to bipolar disorder, 1.5% (n = 200) of 13,125 MS patients diagnosed between 1973 and 2014 were identified with this mood disorder. Its presence significantly increased the risk of MS patients reaching an EDSS score of 4.0 by 58% (95% CI, 1.1-2.28), but not EDSS 3.0 (HR = 1.34; 95% CI, 0.94-1.92) or 6.0 (HR = 1.16; 95% CI, 0.79-1.69).
