Warfarin found to increase adverse outcomes among patients with IPF
DALLAS – Warfarin appears to increase the risk of lung transplant or death for patients with fibrotic lung disease who need anticoagulation therapy, Christopher King, MD, said at the American Thoracic Society’s international conference.
Compared with direct oral anticoagulation (DOAC), warfarin doubled the risk of those outcomes, even after the researchers controlled for multiple morbidities that accompany the need for anticoagulation, said Dr. King, medical director of the transplant and advanced lung disease critical care program at Inova Fairfax (Va.) Hospital.
“The need for anticoagulation in patients with interstitial lung disease is already associated with an increased risk of death or transplant,” he said. Warfarin – but not oral anticoagulation – seems to increase that risk even more “no matter how you analyze it,” he said.
“We know now that fibrosis and coagulation are entwined, and there’s background epidemiologic data showing an increased incidence of venous thromboembolism and acute coronary syndrome in patients with pulmonary fibrosis. This suggests that a dysregulated coagulation cascade may play a role in the pathogenesis of fibrosis.”
The relationship has been explored for the last decade or so. Two recent meta-analyses came to similar conclusions.
In 2013, a 125-patient retrospective cohort study compared clinical characteristics and survival among patients with idiopathic pulmonary fibrosis (IPF) who received anticoagulant therapy with those who did not (Sarcoidosis Vasc Diffuse Lung Dis. 2013 Aug 1;30[2]:121-7). Those who got the treatment had worse survival outcomes at 1 and 3 years than did those who received no therapy (84% vs. 53% and 89% vs. 64%, respectively).
In 2016, a post hoc analysis of three placebo-controlled studies determined that any anticoagulant use independently increased the risk of death among patients with IPF, compared with nonuse: 15.6% vs 6.3% all-cause mortality (Eur Respir J. 2016. doi: 10.1183/13993003.02087-2015).
But these investigations didn’t parse out the types of anticoagulation. Direct oral anticoagulation (DOAC) is much more common now, however, and Dr. King and colleagues wanted to find out how warfarin and DOAC compared.
They retrospectively analyzed data from the Pulmonary Fibrosis Foundation’s database and compared the risk of lung transplant and death for patients on anticoagulation or no anticoagulation and for those receiving DOACs versus warfarin versus no anticoagulation.
The study comprised 1,918 patients, 91% of whom were not on anticoagulation therapy. The remaining 164 were either taking DOAC (n = 83) or warfarin (n = 81). Both of these groups were significantly older than those not on anticoagulation (70 vs. 67 years). As expected , they were significantly more likely to have cardiac arrhythmias, heart failure, or pulmonary embolism or deep vein thrombosis and significantly more likely to be on immunosuppressant therapy or steroids. Their diffusing capacity of lung for carbon dioxide was also significantly lower.
There were no significant lung disease–related differences in anticoagulation therapy, other than a trend toward more use among those with connective tissue disease–associated interstitial lung disease.
Over 2 years, the entire cohort experienced 110 deaths (5.7%), 52 transplants (2.7%), and 29 withdrawals (1.5%). Among patients with IPF, there were 80 deaths (6.7%), 43 transplants (3.6%) and 20 withdrawals (1.7%).
In an unadjusted analysis, anticoagulation more than doubled the risk of an event, compared with no anticoagulation (hazard ratio, 2.4). This was slightly attenuated, but still significant, in a multivariate model that controlled for age, gender, oxygen use, gastroesophageal reflux disease, obstructive sleep apnea, arrhythmia, cancer, heart failure, obesity, venous thromboembolism, and antifibrotics (HR, 1.88).
A second whole-cohort analysis looked at the survival ratios for both warfarin and DOAC, compared with no treatment. In the fully adjusted model, warfarin was associated with a significantly increased risk HR (2.28) but DOAC was not.
The investigators then examined risk in only patients with lung disease. Among those with IPF, the fully adjusted model showed that warfarin nearly tripled the risk of transplant or death (HR, 2.8), while DOAC had no significant effect.
The reason for this association remains unclear, Dr. King said. “Renal failure may be a big reason patients get warfarin instead of DOAC. It’s difficult to say whether these patients were frail or prone to bleeding. Even something like the care team not being as up to date with treatment could be affecting the numbers. And is it the direct effect of warfarin on fibrotic lung disease? Or maybe DOAC has some beneficial effect on pulmonary fibrosis? We don’t know.
“But what we can take away from this is that warfarin is associated with worse outcomes than DOAC in patients with IPF. It seems reasonable to use DOAC over warfarin if there’s no specific contraindication to DOAC. If you have a patient with pulmonary thrombosis who has indications for anticoagulation I would use DOAC, based on the evidence that we now have available.”

Warfarin boosts OA risk in Rotterdam Study
TORONTO – The use of warfarin or related vitamin K antagonists was associated with a more than 100% increased risk of incident or progressive knee or hip osteoarthritis in the Rotterdam Study, Cindy G. Boer reported at the OARSI 2019 World Congress.
A biologically plausible mechanism exists for this relationship, added Ms. Boer, a PhD student with a special interest in the molecular genetics of OA at Erasmus University, Rotterdam, the Netherlands.
In a previous genetic study, she and her coinvestigators identified two genetic variants that result in loss of function of matrix Gla protein (MGP), a key inhibitor of cartilage calcification. They showed that the presence of these alleles was associated with a significantly increased risk of hand OA, which makes sense because increased calcification within a vulnerable joint promotes OA.
“The interesting thing here is that, in order for MGP to inhibit calcification, it needs to be gamma-carboxylated by vitamin K. If it’s not gamma-carboxylated it cannot inhibit calcification,” Ms. Boer said at the meeting sponsored by the Osteoarthritis Research Society International.
This observation led her to hypothesize that patients on warfarin or other vitamin K antagonists might have an increased risk of developing new-onset OA or, if they already had OA, of experiencing disease progression, since their medication inhibits MGP. To test this hypothesis, she and her coinvestigators turned to the landmark Rotterdam Study, a prospective, population-based cohort study of 15,000 participants, ongoing since 1990. Two large cohorts within the study had data available on the incidence and progression of radiographic knee and hip OA, one group over the course of 5 years of follow-up, the other with 10 years.
Serial x-rays of 8,845 knee joints were available, including 657 of warfarin users. Their rate of incident or progressive knee OA was 13%, compared with 5.9% in the nonusers in an analysis adjusted for age, sex, BMI, baseline OA status, and time between study visits.
In a similar vein, the rate of incident or progressive hip OA was 12% in the warfarin users, compared with 3.1% in nonusers.
About 80% of the OA endpoints in this analysis involved incident OA, defined radiographically as Kellgren-Lawrence grade 2. Progressive OA was defined as going from grade 2 at baseline to grade 3-4 during follow-up.
There was a signal of a treatment duration-related effect, with OA rates trending highest in individuals on warfarin for longer than 365 days, followed by those on the oral anticoagulant for more than 100 days, who in turn had higher rates than those on warfarin for less time.
Ms. Boer said an important next step in this research is to replicate the warfarin/OA association in an independent cohort. Also, she and her coworkers are now gathering OA incidence and progression data in patients on direct oral anticoagulants rather than warfarin to test the hypothesis that they will not have an increased rate of OA, compared with nonusers, since these newer agents don’t affect vitamin K. Of course, if they do turn out to have an elevated risk, it would point to one or more of the conditions for which oral anticoagulants are commonly prescribed as the explanation.
She reported having no financial conflicts regarding her study, sponsored by Erasmus University and the Dutch government.

Elderly concussion patients who used statins had lower dementia risk
, compared with similar adults not taking statins.
The findings come from a population-based double cohort study of 28,815 patients in the Ontario Health Insurance Plan. Study patients were enrolled over 20 years, and had a minimum follow-up of 3 years. The study excluded patients hospitalized caused by a severe concussion, those previously diagnosed with delirium or dementia, and those who died within 90 days of their concussions.
Concussions are a common injury in older adults and dementia may be a frequent outcome years afterward, Donald A. Redelmeier, MD, of the University of Toronto and colleagues wrote in a study published in JAMA Neurology. A concussion should not be interpreted as a reason to stop statins, and a potential neuroprotective benefit may encourage medication adherence among patients who are already prescribed a statin.
Of the 28,815 patients studied, 4,727 patients (1 case per 6 patients) developed dementia over the mean follow-up period of 3.9 years. The 7,058 patients who received a statin had a 13% reduced risk of developing dementia, compared with the 21,757 patients who did not (relative risk, 0.87; 95% confidence interval, 0.81-0.93; P less than .001).
Even though statin use was associated with a lower risk, the subsequent incidence of dementia was still twice the population norm in statin users who had concussions, the researchers wrote. The findings indicate concussions are a common injury in older adults and dementia may be a frequent outcome years after concussions.
Statin users who had concussions continued to have a reduced risk of developing dementia after adjustment for patient characteristics, use of other cardiovascular medications, dosage, and depression risk. The statin associated with the greatest risk reduction was rosuvastatin; simvastatin was associated with the least risk reduction. With the possible exception of angiotensin II receptor blockers, no other cardiovascular or noncardiovascular medications were associated with a decreased risk of dementia after a concussion, the researchers wrote.
They also examined data for elderly patients using statins after an ankle sprain and found the risk of dementia was similar for those who did and did not receive statins after the injury.
Factors such as smoking status, exercise, drug adherence, and other unknown aspects of patient health might have influenced the results of the study, the researchers acknowledged. Additionally, a secondary analysis was not statistically powered to distinguish the relative efficacy of statin use before a concussion.
This study was funded in part by a Canada Research Chair in Medical Decision Sciences, the Canadian Institutes of Health Research, the BrightFocus Foundation, and the Comprehensive Research Experience for Medical Students at the University of Toronto. The authors reported no relevant conflicts of interest.

This appears to be the first large study to explore the relationship between statin use, concussions, and the development of dementia. Although statins have anti-inflammatory properties, no trials have linked statins to reduced cognitive impairment. Considering it can be difficult to mitigate against confounding by indication in pharmacologic studies, this observational study included a large group of diverse individuals who developed concussions over a period of 20 years.

The statin associated with the greatest risk reduction was rosuvastatin; simvastatin was associated with the least risk reduction. With the possible exception of angiotensin II receptor blockers, no other cardiovascular or noncardiovascular medications were associated with a decreased risk of dementia after a concussion, the researchers wrote.
They also examined data for elderly patients using statins after an ankle sprain and found the risk of dementia was similar for those who did and did not receive statins after the injury.
Factors such as smoking status, exercise, drug adherence, and other unknown aspects of patient health might have influenced the results of the study, the researchers acknowledged. Additionally, a secondary analysis was not statistically powered to distinguish the relative efficacy of statin use before a concussion.

Benzodiazepines nearly double the odds of spontaneous abortion
Early-pregnancy spontaneous abortion was almost twice as common among women who used benzodiazepines, according to 17 years’ worth of data from the Quebec Pregnancy Cohort, which prospectively collects data on all pregnancies of women covered by the Quebec Public Prescription Drug Insurance Plan.
The findings suggest the need for caution before prescribing benzodiazepines to treat insomnia and mood or anxiety disorders in early pregnancy. “Alternative nonpharmacologic treatments exist and are recommended, but if benzodiazepines are needed, they should be prescribed for short durations,” wrote Odile Sheehy, MSc, of the Research Center at Centre Hospitalier Universitaire Sainte-Justine, Montreal, and colleagues, in a study published in JAMA Psychiatry.
The researchers evaluated data from 27,149 study-eligible women who had a spontaneous abortion after 6 weeks’ gestation and before 20 weeks’ gestation between Jan. 1, 1998, and Dec. 31, 2015. Among filled prescriptions, at least one benzodiazepine was used by 375 (1.4%) of the women. These women were matched with five randomly selected control pregnancies per case. The data were adjusted for diagnoses of mood and anxiety disorders and insomnia as well as for several documented proxies of these diseases, such as concomitant exposure to antidepressants or antipsychotics, visits to a psychiatrist, comorbidities, and hospitalizations.
The investigators found an adjusted odds ratio (aOR) of 1.85 (95% confidence interval, 1.61-2.12) for benzodiazepine use. The odds of spontaneous abortion was increased with use of all types of benzodiazepines evaluated in the study, with aORs as low as 1.13 and as high as 3.43, as well as similar aORs between long-acting and short-acting benzodiazepines (1.81 vs. 1.73, respectively).
While the information is accurate regarding filled prescriptions, the findings might not apply to women with private drug insurance as the study included only women in a prescription drug program, the researchers said. They noted, however, that pregnant women receiving medication insurance from Quebec’s public system have characteristics and comorbidities similar to those of women who are covered by private medication insurance.
One author reported being a consultant for plaintiffs in litigations involving antidepressants and birth defects. No other disclosures were reported.

Lenalidomide may reduce risk of progression from SMM to MM
Lenalidomide can reduce the risk of progression from smoldering multiple myeloma (SMM) to multiple myeloma (MM), according to a phase 2/3 trial.
At 3 years, the rate of progression-free survival (PFS) was 91% in SMM patients randomized to lenalidomide and 66% in those randomized to observation.
However, more than half of patients randomized to lenalidomide discontinued treatment because of toxicity.
These results are scheduled to be presented at the annual meeting of the American Society of Clinical Oncology.
Sagar Lonial, MD, of Winship Cancer Institute, Emory University, Atlanta, discussed the results in a press briefing in advance of the meeting.
A prior trial suggested that lenalidomide plus dexamethasone can improve time to MM development and overall survival in patients with high-risk SMM (Mateos MV et al. NEJM 2013). However, inferior imaging was used in this trial, and the addition of dexamethasone hindered researchers’ ability to isolate the effects of lenalidomide, Dr. Lonial said.
With their trial (NCT01169337), Dr. Lonial and colleagues tested lenalidomide alone and screened patients using magnetic resonance imaging.
The trial enrolled patients with intermediate or high-risk SMM in two phases. In phase 2, all 44 patients received lenalidomide at 25 mg daily on days 1-21 of a 28-day cycle. They also received aspirin at 325 mg on days 1-28.
In the phase 3 portion of the trial, 182 patients were randomized to observation or lenalidomide and aspirin at the aforementioned dose and schedule. Patients were stratified according to time since SMM diagnosis – 1 year or less vs. more than 1 year.
Safety
Dr. Lonial said, in general, lenalidomide was “very well tolerated.” However, 80% of patients in phase 2 and 51% in phase 3 discontinued lenalidomide due to toxicity.
The rates of treatment-related adverse events (AEs) in the phase 2 portion were 34.1% for grade 3 AEs, 11.4% for grade 4, and 4.5% for grade 5. In the phase 3 portion, 35.2% of patients had grade 3 treatment-related AEs, and 5.7% had grade 4 treatment-related AEs.
Common AEs in phase 3 were grade 4 neutrophil count decrease (4.5%) and grade 3 infections (20.5%), hypertension (9.1%), fatigue (6.8%), skin AEs (5.7%), dyspnea (5.7%), and hypokalemia (3.4%).
Efficacy
“It is worth noting that about 50% of patients had an objective response to lenalidomide in both the phase 2 and the phase 3 trial,” Dr. Lonial said. “I think it’s also important to realize that, in the phase 2 portion of this study, of the 44 patients enrolled, 78% of them did not progress to myeloma with a median follow-up of over 5 years.”
In phase 2, PFS was 98% at 1 year, 87% at 3 years, and 78% at 5 years.
In phase 3, PFS was 98% in the lenalidomide arm and 89% in the observation arm at 1 year. At 2 years, PFS was 93% in the lenalidomide arm and 76% in the observation arm. At 3 years, PFS was 91% in the lenalidomide arm and 66% in the observation arm.
“What’s really quite interesting is that each [risk] group appeared to benefit almost equally from the early intervention of lenalidomide as a single agent,” Dr. Lonial said. “[W]hile the high-risk group may be the target now, this may be a fertile area for investigation in the intermediate-risk group as well.”
Dr. Lonial has relationships with AbbVie, Amgen, Bristol-Myers Squibb, Celgene, GlaxoSmithKline, Janssen Oncology, Juno Therapeutics, Merck, Novartis, and Takeda. The trial was funded by the National Institutes of Health.

VA system lags in getting DMARDs to veterans with inflammatory arthritis
MADISON, WISC. – Only half of United States veterans with inflammatory arthritis received disease-modifying medication within 90 days of diagnosis if they received care within the Veterans Health Administration, according to a study presented at the annual meeting of the Spondyloarthritis Research and Treatment Network (SPARTAN).
Over the study period, 58.2% of all inflammatory arthritis patients began a disease-modifying antirheumatic drug (DMARD) within 12 months of diagnosis. Rates of DMARD initiation were similar for patients with rheumatoid arthritis (RA, 57.7%) and psoriatic arthritis (PsA, 64.3%), said the first author of the poster presentation, Sogol S. Amjadi, DO, a resident physician at Bingham Memorial Hospital, Blackfoot, Idaho.
However, at 12 months after diagnosis, only 29.6% of ankylosing spondylitis (AS) patients had not been started on a DMARD. “The ankylosing spondylitis group really had the lowest DMARD initiation over time,” said Dr. Amjadi in an interview.
The study used diagnosis codes and natural language processing to look for incident cases of the three inflammatory arthritides (IAs) among patients receiving care within the Veterans Health Administration from 2007 through 2015.
In all, 12,118 patients with incident IA were identified. Of these, 9,711 had RA, 1,472 had PsA, and 935 had AS. Patients were mostly (91.3%) male, with a mean age of 63.7 years.
Over the study period, 41.2% of IA patients were dispensed a DMARD within 30 days of diagnosis, and 50% received a DMARD within 90 days of diagnosis. Patients with PsA or RA had similar rates of DMARD prescription within 30 days of diagnosis (about 42% and 43%, respectively).
The investigators discovered in their analysis that another factor in prompt treatment was access to specialty care.“Timely access to a rheumatology provider is likely important for early DMARD treatment,” wrote Dr. Amjadi and her coauthors in the poster accompanying the presentation. Of patients who did receive a DMARD, 82.7% had received rheumatology specialty care before nonbiologic DMARD dispensing, as had 90.0% of patients receiving biologic DMARDs. Over the entire study period, about 10% of all IA patients had biologic DMARD exposure.
There was a trend over time for increased DMARD dispensing, said the investigators. “The percentage of IA patients with DMARD exposure during the 12-month follow-up period increased from 48.8% in 2008 to 66.4% in 2015.”
For AS patients, early DMARD prescribing rates rose from about 20% in 2007 to nearly 30% in 2015. “DMARD treatment rates during the initial 12 months after diagnosis increased between 2007 and 2015, but nontreatment remained common, particularly in patients with AS,” wrote the investigators. “Delays in treatment for inflammatory arthritis are associated with unfavorable outcomes, including impaired quality of life, irreversible joint damage, and disability.”

Insomnia meds get boxed warning from FDA
The Food and Drug Administration will now require that certain
Complex sleep behaviors have been seen with these medications in patients with and without a history of them, at low doses, and even after one dose of the medication. They’ve also been observed with and without concomitant use of alcohol or other CNS depressants.
Health care professionals should advise patients about these risks, even though they are rare. Patients should contact health care professionals if they either experience a complex sleep behavior while not fully awake on one of these medicines or have performed activities they don’t remember while taking the medicine.
More information about these risks and the safety warnings can be found in the FDA’s safety announcement. Other information is also available in a press announcement from the agency.

Patients should contact health care professionals if they either experience a complex sleep behavior while not fully awake on one of these medicines or have performed activities they don’t remember while taking the medicine.
More information about these risks and the safety warnings can be found in the FDA’s safety announcement. Other information is also available in a press announcement from the agency.
FDA approves Qternmet XR as adjunct therapy for glycemic improvement in type 2 diabetes
The Food and Drug Administration has approved Qternmet XR (dapagliflozin/saxagliptin/metformin) as an oral adjunct therapy to diet and exercise for the improvement of glycemic control in patients with type 2 diabetes, according to AstraZeneca.
FDA approval is based on results from a pair of phase 3 trials that tested different combinations of dapagliflozin and saxagliptin in patients with inadequately controlled type 2 diabetes who were also receiving metformin over a 24-week period. In both trials, treatment with dapagliflozin/saxagliptin/metformin decreased hemoglobin A1c by statistically significant amounts, and increased the number of patients with HbA1c levels below 7%
The safety results of Qternmet XR was consistent with each component medication’s known profile.

Direct pharmacy dispensing of naloxone linked to drop in fatal overdoses
investigators reported.
By contrast, state laws that stopped short of allowing pharmacists to directly dispense the opioid antagonist did not appear to impact mortality, according to the report, which appears in JAMA Internal Medicine (2019 May 6. doi: 10.1001/jamainternmed.2019.0272).
The report, based on state-level trends tracked from 2005 to 2016, indicates that fatal opioid overdoses fell by nearly one-third in states that adopted direct dispensing laws as compared with states that adopted other naloxone laws.
That finding suggests that the policy type determines whether a naloxone law is useful in combating fatal opioid overdoses, said Rahi Abouk, PhD, of William Paterson University, Wayne, N.J. and co-authors of the paper.
“Enabling distribution through various sources, or requiring gatekeepers, will not be as beneficial,” Dr. Abouk and co-authors said in their report.
The current rate of deaths from fentanyl, heroin, and prescription analgesic overdose has outpaced all previous drug epidemics on record, and even surpasses the number of deaths in the peak year of the HIV epidemic of the 1980s, Dr. Abouk and colleagues wrote in their paper.
The number of states with naloxone access laws grew from just 2 in 2005 to 47 by 2016, including 9 states that granted direct authority to pharmacists and 38 that granted indirect authority, according to the researchers.
The analysis of overdose trends from 2005 to 2016 was based on naloxone distribution data from state Medicaid agencies and opioid-related mortality data from a national statistics system. Forty percent of nonelderly adults with an opioid addiction are covered by Medicaid, the researchers said.
They found that naloxone laws granting pharmacists direct dispensing authority were linked to a drop in opioid deaths that increased in magnitude over time, according to researchers. The mean number of opioid deaths dropped by 27% in the second year after adoption of direct authority laws, relative to opioid deaths in states with indirect access laws, while in subsequent years, deaths dropped by 34%.
Emergency department visits related to opioids increased by 15% in direct authority states 3 or more years after adoption, as compared to states that did not adopt direct authority laws. According to investigators, that translated into 15 additional opioid-related emergency department visits each month.
That increase suggests that, alongside direct dispensing laws, “useful interventions” and connections to treatment are needed for the emergency department, according to Dr. Abouk and colleagues.
“This is the location where such programs may be the most effective,” they said in their report.
Future research should be done to determine whether removing gatekeepers increases the value of naloxone distribution policies, they concluded in the report.
Dr. Abouk had no disclosures. Co-authors on the study reported funding and conflict of interest disclosures related to the National Institute on Drug Abuse and the Centers for Disease Control and Prevention.

FDA approves ivosidenib frontline for certain AML patients
The Food and Drug Administration has approved ivosidenib (Tibsovo) for newly diagnosed acute myeloid leukemia (AML) with a susceptible IDH1 mutation in patients who are at least 75 years old or have comorbidities preventing the use of intensive induction chemotherapy.
In July 2018, the FDA approved ivosidenib for adults with relapsed or refractory AML with a susceptible IDH1 mutation.
The latest approval was based on results from an open-label, single-arm, multicenter trial of patients with newly diagnosed AML with an IDH1 mutation. Patients were treated with 500 mg ivosidenib daily until disease progression, development of unacceptable toxicity, or hematopoietic stem cell transplantation; the median age of the 28 patients treated with ivosidenib was 77 years.
Of the 28 patients treated, 12 achieved complete remission or complete remission with partial hematologic recovery; 7 of the 17 transfusion-dependent patients achieved transfusion independence for at least 8 weeks.
The most common adverse events were diarrhea, fatigue, edema, decreased appetite, leukocytosis, nausea, arthralgia, abdominal pain, dyspnea, differentiation syndrome, and myalgia. The drug’s prescribing information includes a boxed warning on the risk of differentiation syndrome.
“The recommended ivosidenib dose is 500 mg orally once daily with or without food until disease progression or unacceptable toxicity. For patients without disease progression or unacceptable toxicity, treatment is recommended for a minimum of 6 months to allow time for clinical response,” the FDA noted.
