Pulmonology

To the Editor: Regarding the article about a man with rapidly progressive pleural effusion by Zoumot et al in the January 2019 issue,¹ there was some inconsistency between the teaching points and the actions taken.

Question 1 asked what was the most likely cause of the patient’s pleuritic chest pain. Pulmonary embolism was an unlikely diagnosis, given the patient’s presentation and his normal D-dimer level, which the text acknowledges, but then proceeds to state that computed tomographic angiography of the chest was done anyway.

After pleural effusion was diagnosed, question 2 asked what was the best management strategy for the patient at that time. The best management strategy was to give oral antibiotics with close follow-up because the patient was at low risk of a poor outcome, but he was advised to be admitted for intravenous antibiotics anyway.

I’m not quite sure of the point of the didactic exercise when actions are not consistent with the analytic rationale for testing and treatment.

In Reply: We thank Dr. Davidson for his comments. Indeed, the teaching points may appear inconsistent with the actual patient journey in this case. In the real world, physicians from different teams and specialties are involved in the care of a patient, and medical practice may not strictly adhere to guidelines.

In question 1, the emergency department physician decided to proceed with computed tomographic pulmonary angiography to rule out pulmonary embolism. Based on best practice guidelines, pulmonary angiography was not indicated, as the clinical pretest probability of pulmonary embolism was low, supported by the patient’s negative D-dimer test. When we wrote the article, as we already had the scan, we used it to support the learning points in terms of findings on computed tomography at the early stage of a developing empyema, and also to support that the scan was in fact not indicated (not the other way around).

As for question 2, specific data-driven guidelines do not exist on how best to manage patients with bronchopneumonia with an early evolving parapneumonic effusion. In the text that follows question 2, we stated that management as an inpatient or outpatient would have been reasonable. Although we considered the patient at low risk for a poor outcome, we offered inpatient admission at the time for better control of his severe pleuritic pain (this could have been made clearer in the text), as well as close monitoring of his evolving parapneumonic effusion, and we do not believe that this contradicts the teaching points of this case.

The 2018-2019 flu season again showed real signs of ending as influenza activity levels dropped during the week ending March 23, according to the Centers for Disease Control and Prevention.

Despite those declines, however, current levels of influenza-like illness (ILI) activity are still elevated enough that the CDC issued a health advisory on March 28 to inform clinicians about the “increasing proportion of activity due to influenza A(H3N2) viruses, continued circulation of influenza A(H1N1) viruses, and low levels of influenza B viruses.”

The CDC’s weekly flu report, released March 29, does show that the overall burden is improving. The national proportion of outpatient visits for ILI dropped from 4.3% for the week ending March 16 to 3.8% for the latest reporting week, the CDC’s influenza division reported. The figure for March 16 was originally reported to be 4.4% but was revised in the new report.

The length of this years’ flu season, when measured as the number of weeks at or above the baseline level of 2.2%, is now 18 weeks. By this measure, the last five seasons have averaged 16 weeks, the CDC noted.

Influenza was considered widespread in 34 states and Puerto Rico for the week ending March 23, down from 44 states the previous week. The number of states at the highest level of ILI activity on the CDC’s 1-10 scale dropped from 20 to 11, and those in the high range (8-10) dropped from 26 to 20, data from the CDC’s Outpatient ILI Surveillance Network show.

There was one flu-related pediatric death during the week of March 23 but none reported from earlier weeks, which brings the total to 77 for the 2018-2019 season, the CDC said.

NEW ORLEANS – Contrary to previously published data suggesting continuous positive airway pressure (CPAP) produces weight gain in patients with obstructive sleep apnea (OSA), new study findings presented at the annual meeting of the Endocrine Society provided data supporting the exact opposite conclusion.

Ted Bosworth/MDedge News

“We think the data are strong enough to conclude that combining CPAP with a weight-loss program should be considered for all OSA patients. The weight-loss advantage is substantial,” reported Yuanjie Mao, MD, PhD, of the University of Arkansas for Medical Sciences, Little Rock.

Both weight loss and CPAP have been shown to be effective for the treatment of OSA, but concern that CPAP produces a counterproductive gain in weight was raised by findings in a meta-analysis in which CPAP was associated with increased body mass index (Thorax. 2015 Mar;70:258-64). As a result of that finding, some guidelines subsequently advised intensifying a weight-loss program at the time that CPAP is initiated to mitigate the weight gain effect, according to Dr. Mao. However, he noted that prospective data were never collected, so a causal relationship was never proven. Now, his data support the opposite conclusion.

In the more recent study, 300 patients who had participated in an intensive weight-loss program at his institution were divided into three groups: OSA patients who had been treated with CPAP, symptomatic OSA patients who had not been treated with CPAP, and asymptomatic OSA patients not treated with CPAP. They were compared retrospectively for weight change over a 16-week period.

“This was a very simple study,” said Dr. Mao, who explained that several exclusions, such as thyroid dysfunction, active infection, and uncontrolled diabetes, were used to reduce variables that might also affect weight change. At the end of 16 weeks, the median absolute weight loss in the CPAP group was 26.7 lb (12.1 kg), compared with 21 lb (9.5 kg) for the symptomatic OSA group and 19.2 lb (8.7 kg) for the asymptomatic OSA group. The weight loss was significantly greater for the CPAP group (P less than .01), compared with either of the other two groups, but not significantly different between the groups that were not treated with CPAP.

“The differences remained significant after adjusting for baseline BMI [body mass index], age, and gender,” Dr. Mao reported.

Asked why his data contradicted the previously reported data, Dr. Mao said that the previous studies were not evaluating CPAP in the context of a weight-loss program. He contends that when CPAP is combined with a rigorous weight-reduction regimen, there is an additive benefit from CPAP.

According to Dr. Mao, these data bring the value of CPAP for weight loss full circle. Before publication of the 2015 meta-analysis, it was widely assumed that CPAP helped with weight loss based on the expectation that better sleep quality would increase daytime activity. However, in the absence of strong data confirming that effect, Dr. Mao believes the unexpected results of the 2015 study easily pushed the pendulum in the opposite direction.

“The conclusion that CPAP increases weight was drawn from studies not designed to evaluate a weight-loss effect in those participating in a weight-loss program,” Dr. Mao explained. His study suggests that it is this combination that is important. He believes the observed effect from better sleep quality associated with CPAP is not necessarily related to better daytime function alone.

“Patients who sleep well also have more favorable diurnal changes in factors that might be important to weight change, such as leptin resistance and hormonal secretion,” he said. Although more work is needed to determine whether these purported mechanisms are important, he thinks his study has an immediate clinical message.

“Patients with OSA who are prescribed weight loss should also be considered for CPAP for the goal of weight loss,” Dr. Mao said. “We think this therapy should be started right away.”

NEW ORLEANS – The incidence of pulmonary embolism diagnosed in hospitalized U.S. patients nearly doubled during the period 2004-2015 based on data collected by the National Inpatient Sample.

During 2004-2015 the incidence of all diagnosed pulmonary embolism (PE), based on discharge diagnoses, rose from 5.4 cases/1,000 hospitalized patients in 2004 to 9.7 cases/1,000 hospitalized patients in 2015, an 80% increase, Joshua B. Goldberg, MD said at the annual meeting of the American College of Cardiology. The incidence of major PE – defined as a patient who needed vasopressor treatment, mechanical ventilation, or had nonseptic shock – rose from 7.9% of all hospitalized PE diagnoses in 2004 to 9.7% in 2015, a 23% relative increase.

Mitchel L. Zoler/MDedge News

The data also documented a shifting pattern of treatment for all hospitalized patients with PE, and especially among patients with major PE. During the study period, treatment with systemic thrombolysis for all PE rose nearly threefold, and catheter-directed therapy began to show a steady rise in use from 0.2% of all patients in 2011 (and before) to 1% of all patients by 2015. Surgical intervention remained lightly used throughout, with about 0.2% of all PE patients undergoing surgery annually.

Most of these intervention options focused on patients with major PE. Among patients in this subgroup with more severe disease, use of one of these three types of interventions rose from 6% in 2004 to 12% in 2015, mostly driven by a rise in systemic thrombolysis, which jumped from 3% of major PE in 2004 to 9% in 2015. However, the efficacy of systemic thrombolysis in patients with major PE remains suspect. In 2004, 39% of patients with major PE treated with systemic thrombolysis died in hospital; in 2015 the number was 47%. “The data don’t support using systemic thrombolysis to treat major PE; the mortality is high,” noted Dr. Goldberg, a cardiothoracic surgeon at Westchester Medical Center in Valhalla, N.Y.

Although catheter-directed therapy began to be much more widely used in U.S. practice starting in about 2015, during the period studied its use for major PE held fairly steady at roughly 2%-3%, but this approach also showed substantial shortcomings for the major PE population. These sicker patients treated with catheter-directed therapy had 37% mortality in 2004 and a 31% mortality in 2015, a difference that was not statistically significant. In general, PE patients enrolled in the catheter-directed therapy trials were not as sick as the major PE patients who get treated with surgery in routine practice, Dr. Goldberg said in an interview.

The data showed much better performance using surgery, although only 1,237 patients of the entire group of 713,083 PE patients studied in the database underwent surgical embolectomy. Overall, in-hospital mortality in these patients was 22%, but in a time trend analysis, mortality among all PE patients treated with surgery fell from 32% in 2004 to 14% in 2015; among patients with major PE treated with surgery, mortality fell from 52% in 2004 to 21% in 2015.

Dr. Goldberg attributed the success of surgery in severe PE patients to the definitive nature of embolectomy and the concurrent use of extracorporeal membrane oxygenation that helps stabilize acutely ill PE patients. He also cited refinements that surgery underwent during the 2004-2015 period based on the experience managing chronic thromboembolic pulmonary hypertension, including routine use of cardiopulmonary bypass during surgery. “Very high risk [PE] patients should go straight to surgery, unless the patient is at high risk for surgery because of conditions like prior sternotomy or very advanced age, in which case catheter-directed therapy may be a safer option, he said. He cited a recent 5% death rate after surgery at his center among patients with major PE who did not require cardiopulmonary resuscitation.

The database Dr. Goldberg and his collaborator reviewed included 12,735 patients treated by systemic thrombolysis, and 2,595 treated by catheter-directed therapy. Patients averaged 63 years old. The most common indicator of major PE was mechanical ventilation, used on 8% of all PE patients in the study. Non-septic shock occurred in 2%, and just under 1% needed vasopressor treatment.

Published guidelines on PE management from several medical groups are “vague and have numerous caveats,” Dr. Goldberg said. He is participating in an update to the 2011 PE management statement from the American College of Cardiology and American Heart Association (Circulation. 2011 April 26;123[16]:1788-1830).

The study received no commercial funding. Dr. Goldberg had no disclosures.

Surgical intervention remained lightly used throughout, with about 0.2% of all PE patients undergoing surgery annually.

Most of these intervention options focused on patients with major PE. Among patients in this subgroup with more severe disease, use of one of these three types of interventions rose from 6% in 2004 to 12% in 2015, mostly driven by a rise in systemic thrombolysis, which jumped from 3% of major PE in 2004 to 9% in 2015. However, the efficacy of systemic thrombolysis in patients with major PE remains suspect. In 2004, 39% of patients with major PE treated with systemic thrombolysis died in hospital; in 2015 the number was 47%. “The data don’t support using systemic thrombolysis to treat major PE; the mortality is high,” noted Dr. Goldberg, a cardiothoracic surgeon at Westchester Medical Center in Valhalla, N.Y.

Although catheter-directed therapy began to be much more widely used in U.S. practice starting in about 2015, during the period studied its use for major PE held fairly steady at roughly 2%-3%, but this approach also showed substantial shortcomings for the major PE population. These sicker patients treated with catheter-directed therapy had 37% mortality in 2004 and a 31% mortality in 2015, a difference that was not statistically significant. In general, PE patients enrolled in the catheter-directed therapy trials were not as sick as the major PE patients who get treated with surgery in routine practice, Dr. Goldberg said in an interview.

The data showed much better performance using surgery, although only 1,237 patients of the entire group of 713,083 PE patients studied in the database underwent surgical embolectomy. Overall, in-hospital mortality in these patients was 22%, but in a time trend analysis, mortality among all PE patients treated with surgery fell from 32% in 2004 to 14% in 2015; among patients with major PE treated with surgery, mortality fell from 52% in 2004 to 21% in 2015.

Dr. Goldberg attributed the success of surgery in severe PE patients to the definitive nature of embolectomy and the concurrent use of extracorporeal membrane oxygenation that helps stabilize acutely ill PE patients. He also cited refinements that surgery underwent during the 2004-2015 period based on the experience managing chronic thromboembolic pulmonary hypertension, including routine use of cardiopulmonary bypass during surgery. “Very high risk [PE] patients should go straight to surgery, unless the patient is at high risk for surgery because of conditions like prior sternotomy or very advanced age, in which case catheter-directed therapy may be a safer option, he said. He cited a recent 5% death rate after surgery at his center among patients with major PE who did not require cardiopulmonary resuscitation.

The database Dr. Goldberg and his collaborator reviewed included 12,735 patients treated by systemic thrombolysis, and 2,595 treated by catheter-directed therapy. Patients averaged 63 years old. The most common indicator of major PE was mechanical ventilation, used on 8% of all PE patients in the study. Non-septic shock occurred in 2%, and just under 1% needed vasopressor treatment.

Published guidelines on PE management from several medical groups are “vague and have numerous caveats,” Dr. Goldberg said. He is participating in an update to the 2011 PE management statement from the American College of Cardiology and American Heart Association (Circulation. 2011 April 26;123[16]:1788-1830).

The study received no commercial funding. Dr. Goldberg had no disclosures.

NEW ORLEANS – The incidence of pulmonary embolism diagnosed in hospitalized U.S. patients nearly doubled during the period 2004-2015 based on data collected by the National Inpatient Sample.

During 2004-2015 the incidence of all diagnosed pulmonary embolism (PE), based on discharge diagnoses, rose from 5.4 cases/1,000 hospitalized patients in 2004 to 9.7 cases/1,000 hospitalized patients in 2015, an 80% increase, Joshua B. Goldberg, MD said at the annual meeting of the American College of Cardiology. The incidence of major PE – defined as a patient who needed vasopressor treatment, mechanical ventilation, or had nonseptic shock – rose from 7.9% of all hospitalized PE diagnoses in 2004 to 9.7% in 2015, a 23% relative increase.

A diagnostic algorithm adapted for use in pregnancy safely ruled out acute pulmonary embolism in nearly 500 women with suspected pulmonary embolism enrolled in a recent prospective study, investigators are reporting.

Using the adapted algorithm, there was only one deep-vein thrombosis (DVT) and no pulmonary embolism (PE) in follow-up among those women, according to the investigators, including senior author Menno V. Huisman, MD, PhD, of the department of thrombosis and hemostasis at Leiden (Netherlands) University Medical Center and his coauthors.

The main advantage of the algorithm is that it averted CT pulmonary angiography in nearly 40% of patients, thus sparing radiation exposure to mother and fetus in many cases, the investigators added.

“Our algorithm provides solid evidence for the safe management of suspected PE in pregnant women, with selective use of CT pulmonary angiography,” Dr. Huisman and colleagues said in their March 21 report in the New England Journal of Medicine.

In a previous clinical trial, known as the YEARS study, a specialized diagnostic algorithm had a low incidence of failure in men and women with clinically suspected PE, as shown by a venous thromboembolism (VTE) rate of just 0.61% at 3 months and by use of CT pulmonary angiography that was 14 percentage points lower than with a conventional algorithmic approach.

For the current study, Dr. Huisman and his coinvestigators took the YEARS algorithm and adapted it for use in pregnant women with suspected PE presenting at 1 of 18 centers in the Netherlands, France, and Ireland.

Their adapted algorithm was based on the three criteria investigators said were most predictive in the YEARS trial, namely, clinical signs of symptoms of DVT, hemoptysis, and PE as the most likely diagnosis. Patients also underwent D-dimer testing, and if they had clinical signs and symptoms of DVT, underwent compression utrasonography of the symptomatic leg.

Pulmonary embolism was considered ruled out in patients who met none of the three YEARS criteria and had a D-dimer under 1,000 ng/mL, or if they met one to three YEARS criteria and had a D-dimer under 500 ng/mL. Otherwise, patients underwent CT pulmonary angiography and started anticoagulant treatment if results of that test indicated PE.

The primary endpoint of the study was the cumulative 3-month incidence of symptomatic VTE among patients with PE ruled out by this algorithm.

Of 498 patients participating in the study, 477 (96%) had a negative result on the adapted YEARS algorithm at baseline, while 20 (4.0%) received a diagnosis of PE, according to results of the study. One patient was lost to follow-up.

Of the 477 patients with negative results, 1 patient (0.21%) had a diagnosis of symptomatic DVT over the 3 months of follow-up, investigators reported, adding that there were no PE diagnoses over the follow-up period.

That patient with the DVT diagnosis met none of the three YEARS criteria and had a D-dimer level of 480 ng/mL, and so did not undergo CT pulmonary angiography, investigators said.

In the worst-case scenario, the VTE incidence would have been 0.42%, assuming the one patient lost to follow-up would have had a VTE diagnosis over the 3-month follow-up period, they added.

“These data meet the proposed criteria for assessing the safety of diagnostic methods in VTE, even in the context of a low baseline prevalence of disease,” Dr. Huisman and his colleagues wrote.

Overall, CT pulmonary angiography was avoided – avoiding potential radiation exposure-related harms– in 39% of the patients, the investigators said, noting that the proportion of women avoiding the diagnostic test decreased from 65% for those evaluated in the third trimester, 46% in the second trimester, and 32% in the third.

“This decreasing specificity can be explained by the physiological rise in the D-dimer level that commonly occurs during pregnancy,” said Dr. Huisman and his coauthors.

The study was supported by unrestricted grants from Leiden University Medical Center and 17 other participating hospitals. Many authors reported financial ties to the pharmaceutical industry.

The decline of influenza activity remains slow, largely “driven by a wave of H3N2 virus activity” in recent weeks, according to the Centers for Disease Control and Prevention.

Fewer states reported the highest level of influenza-like illness (ILI) activity on the CDC’s 1-10 scale for the week ending March 16, but the national proportion of outpatient visits for ILI was 4.4% for the second consecutive week, the CDC’s influenza division reported March 22. The outpatient-visit figure for the week ending March 9 was originally reported as 4.5% last week, but it has been revised down to 4.4% this week.

Another measure of activity – the percentage of respiratory specimens testing positive for influenza viruses in clinical laboratories – actually increased slightly during the week ending March 16, the CDC noted.

For the current week, there were 26 states in the high (8-10) range of activity – 20 states were at level 10 and another 6 states were at level 8 – compared with the previous week, when 21 states were at level 10 and 30 states were in the high range, the CDC’s Outpatient ILI Surveillance Network reported.

There were eight ILI-related deaths in children reported during the week ending March 16, seven of which occurred in previous weeks. The total for the 2018-2019 season so far is 76, the CDC said.

New preliminary estimates on influenza’s burden nationally put the total number of deaths at 25,000-41,500 since the beginning of the season on Oct. 1, 2018. There also have been 375,000-454,000 flu-related hospitalizations, 13.2 million to 15.4 million medical visits, and 28.5 to 32.8 million individual illnesses, the CDC said.

Since the CDC “expects flu activity to remain elevated for a number of weeks,” it continues to recommend flu vaccination and the use of influenza antiviral drugs as “an important second line of defense that can be used to treat flu illness. H3N2 viruses are typically associated with more severe illness in older adults, and flu vaccine may protect less well against H3N2 illness in older adults, making prompt treatment with flu antivirals in this age group especially important during the current period of H3N2 predominance.”

The Food and Drug Administration has approved solriamfetol (Sunosi) for the treatment of excessive daytime sleepiness in patients with narcolepsy or obstructive sleep apnea. It is the first dopamine and norepinephrine reuptake inhibitor approved to treat those conditions.

Wikimedia Commons/FitzColinGerald/Creative Commons License

Approval was based on results from TONES (Treatment of Obstructive Sleep Apnea and Narcolepsy Excessive Sleepiness), a phase 3 study that combined four randomized, placebo-controlled trials assessing solriamfetol at various doses, compared with a placebo. After 12 weeks, 68%-74% of patients taking solriamfetol at 75 mg and 78%-90% of those taking solriamfetol at 150 mg reported improvement as assessed by the Patient Global Impression of Change scale.

Solriamfetol is approved at 75 mg and 150 mg for patients with narcolepsy and at 37.5 mg, 75 mg, and 150 mg for patients with obstructive sleep apnea. The most common adverse events associated with solriamfetol are headache, nausea, decreased appetite, and anxiety.

“Excessive daytime sleepiness can negatively impact the daily lives of people living with narcolepsy or obstructive sleep apnea at work, at home, or in daily activities. With this approval, a new, daytime medicine that can provide sustained wakefulness throughout the day will be available for patients,” Bruce Cozadd, chairman and CEO of Jazz Pharmaceuticals, said in the press release.
