NEW YORK –The work of the dermatologist doesn’t need to stop at the lips, according to Nasim Fazel, MD, DDS, a board-certified dermatologist and dentist. With a light touch driven by understanding of the oral mucosa, dermatologists can confidently obtain high-quality specimens and manage many intra-oral cutaneous conditions, she said, speaking at a session focused on oral health and procedures at the American Academy of Dermatology summer meeting.

Whether to perform an incisional or excisional biopsy on the lips or within the oral cavity is a decision driven by the clinical scenario, said Dr. Fazel, professor of clinical dermatology and director of the oral mucosal disease clinic at the University of California, Davis. Variables to consider, she said, include the size of the lesion, as well as whether the lesion is symptomatic or there’s any functional impairment. Other factors to bear in mind are whether the patient has any comorbid inflammatory conditions and whether the lesion could be malignant.

An excisional biopsy is a good procedure for small lesions that are thought to be benign, especially if they are exophytic, she noted. An example would be a traumatic fibroma, she said. This technique is also appropriate if there’s concern for dysplasia or malignancy if an office excisional biopsy is feasible given lesion size and location.

On the labial mucosa, an elliptical incision is often a good choice.
 

Cutaneous lip procedures

On the cutaneous lip, a punch incision can be feasible. The vermilion border should be marked to maintain orientation. “Avoid transecting the vermilion border to the extent that it’s possible,” said Dr. Fazel. Keep the vascular anatomy in mind as well, she added, since there’s a risk of severing the superior or inferior labial artery with procedures in this area. If this should happen, the branch can be identified and ligated with 4-0 fast gut or chromic gut suture material, she advised.

Another option on the cutaneous lip is shave removal. Here, a chalazion clamp can be used for both exposure and hemostasis. “Always suture parallel to the lip lines, and caution the patient that there may be significant, noticeable blanching when lip anesthesia’s used,” she said.
 

Gingival and tongue procedures

Moving to territory that may be less familiar for some dermatologists, Dr. Fazel walked through the process of a gingival punch biopsy. “Use local anesthetic, but a small quantity is sufficient,” she said. Using gentle pressure, the operator can work the punch instrument down to periosteal bone. At that point, just scissors can be used for undermining the specimen, with minimal disturbance of the mucosal surface.

Hemostasis after a gingival punch can be accomplished with silver nitrate or aluminum chloride or by electrocautery. A permanent defect in the gingiva can occur even with good technique, she said – a fact that should be included in the informed consent document for the procedure.

For lesions on the tongue, a shave removal can be considered, as can an incisional punch biopsy. An assistant’s hands are invaluable for stabilizing the tongue, said Dr. Fazel, illustrating that small dry gauze squares help achieve a good grip.
 

Considerations in biopsy technique

Dr. Fazel offered some tips and considerations when a punch biopsy is being done in the context of a chronic oral inflammatory condition, and the plan is to submit for hematoxylin and eosin (H&E) staining and direct immunofluorescence (DIF). Conditions where an intraoral punch biopsy would be considered include bullous or mucous membrane pemphigoid, pemphigus, lichen planus, and systemic lupus erythematosus, she said.

“Select a site with the most significant inflammatory changes” and aim for the most anterior site that exhibits these characteristics to maximize exposure and ensure a good specimen. The labial mucosa is a better choice in general than buccal mucosa, she said. “Maxillary and mandibular sulci are tricky sites,” especially when perilesional and lesional tissue should be included in the biopsies.

Next, Dr. Fazel walked attendees through general principles of preparing for and performing punch biopsies for H&E and DIF. In planning the biopsies, the DIF specimen should ideally be collected before the H&E specimen because the former technique will have higher yield when the specimen is taken from a less bloody field. “The yield of DIF is higher from the gingiva than from nonkeratinized surfaces.”

When infiltrating the biopsy site with local anesthesia, the needle should be centered within the lesion or general area to be biopsied, and care should be taken to maintain the orientation of the lesion to the surrounding tissue. Anesthesia can be infiltrated within the submucosal plane; the resultant ballooning will elevate the tissue to be biopsied and ease the procedure, she said.

Choose a 3-mm punch tool for gingival biopsies; 4 mm is a good size for other nonkeratinized surfaces. Unlike the procedure used for cutaneous biopsies, on delicate oral tissues, “you don’t need to hub your punch tool,” Dr. Fazel said. Similarly, the tool can be driven with firm rotation in one direction, rather than ratcheting back and forth, which may fray and deform the biopsy margins, she added. The specimen can be freed from surrounding mucosa with scissors alone and a gentle snipping motion; everting the tissue will help achieve the desired clean and gentle technique.

Because of the delicacy of the tissue, “it’s important to minimize the use of forceps, as well as any unnecessary manipulation of tissue in the process of specimen collection,” she said.
 

Salivary gland biopsies and intraoral suturing

Even minor salivary glands can be biopsied in a fairly straightforward way, though there’s a risk of short- and long-term loss of sensation, as well as more scarring than in other routine intraoral biopsies. Though these salivary glands lie just beneath the oral mucosa, care must be taken to avoid laceration of the orbicularis oris muscle during excision, noted Dr. Fazel. With a minor salivary gland biopsy, as with some other intraoral procedures, sutures will be needed. Consideration for the friability of the oral mucosa should drive suture material choice and closure technique.

First, “take bigger bites on each side of the incision, to minimize the risk of the suture tearing through the mucosa,” she said. Avoid forceps while suturing if possible, but be gentle if they are employed, “and be gentle tying knots: retract the mucosa as little as possible and cinch the knots down tightly with your fingers.”

Electrocautery, silver nitrate, and aluminum chloride are all reasonable options for hemostasis, although patients should be alerted that the tissue will have a charred appearance if electrocautery is used. Primary closure may be all that’s needed for hemostasis, said Dr. Fazel.

If nonabsorbable suture materials are used, nylon and prolene should be avoided since they tend to tear through the oral mucosa. Soft or braided silk are good choices, she said, and sutures can come out in 5-7 days.

Absorbable sutures have the advantage of not requiring removal, but they can be more irritating to the surrounding mucosa. Chromic or fast gut are the choices here, said Dr. Fazel. Whether absorbable or nonabsorbable sutures are placed, the size should be 4-0 or 5-0, she said.
 

Postoperative care, complications, and the limits of the dermatologist

Postoperatively, patients should know that swelling is to be expected, especially with procedures like minor salivary gland biopsies that involve the lip. Icing 15 minutes per hour for the first few hours will help with swelling; wound care is optimized with gentle salt water rinses. A bland diet that avoids acidic, spicy, and excessively hot foods and beverages will minimize wound irritation. Foods with sharp edges like chips, crackers, and nuts can actually catch sutures and cause pain and bleeding, so these too should be avoided.

As with dental work, care should be taken with eating or drinking until anesthesia has worn off, which may take up to 3 hours. Patients should also be cautioned that sutures are likely to come out prematurely just because of the mobility of the structures of the mouth with normal activities such as eating and talking.

Should a wound infection occur, said Dr. Fazel, it’s likely that mixed aerobic and anaerobic bacteria are to blame; accordingly, broad-spectrum beta-lactam antibiotics can be a good first-line course. More severe infections are more likely to have an anaerobic or gram-negative etiology; metronidazole is a reasonable choice for anaerobic coverage, she noted. The life-threatening complication not to miss is cellulitis of the floor of the mouth, or Ludwig angina. The swelling results in superior and posterior displacement of the tongue, obstructing the upper airway, so any patient suspected of having Ludwig angina needs emergent evaluation and treatment.

When should a dermatologist consider referral to an otolaryngologist rather than diving into a biopsy in the dermatology clinic? If the area of concern is on the posterior third of the tongue, access without special tools or higher levels of anesthesia becomes tricky, Dr. Fazel pointed out. The posterior hard palate, the soft palate, and the floor of the mouth are also regions best left to otolaryngologists, she said.

PARIS – Rivaroxaban monotherapy bested combination therapy with rivaroxaban and an antiplatelet agent for patients with atrial fibrillation and stable coronary artery disease, with significantly more deaths and bleeding events seen with combination therapy.

Catherine Hackett/MDedge News

The pronounced imbalance in all-cause and cardiovascular mortality (the hazard ratio favoring rivaroxaban monotherapy was 9.72) came as a surprise, and led to early cessation of the multisite Japanese trial, lead investigator Satoshi Yasuda, MD, said at the annual congress of the European Society of Cardiology.

Several previous clinical trials had studied a reduced antithrombotic regimen for patients with atrial fibrillation (AFib) after percutaneous coronary intervention (PCI), said Dr. Yasuda, professor of medicine at Tohoku University, Sendai, Japan. Current guidelines recommend triple therapy with an oral anticoagulant plus aspirin and a P2Y12 inhibitor for the shortest duration possible, with combination therapy of an anticoagulant plus a P2Y12 inhibitor for up to 12 months. Once the 1-year post-PCI mark is reached, current European and American guidelines or consensus documents recommend monotherapy with an oral anticoagulant if AFib persists and the patient has stable coronary artery disease (CAD), explained Dr. Yasuda. “However, this approach has yet to be supported by evidence from randomized, controlled trials,” he said, adding “substantial numbers of patients in this situation continue to be treated with combination therapy, which indicates a gap between guidelines and clinical practice.”

The Atrial Fibrillation and Ischemic events with Rivaroxaban in Patients With Stable Coronary Artery Disease Study (AFIRE), he said, was designed to address this practice gap, randomizing 2,200 individuals to receive monotherapy with rivaroxaban or combination therapy. A total of 1,973 patients completed follow-up.

Patients were included in the randomized, open-label, parallel-group trial if they had AFib and stable CAD and were more than 1 year out from revascularization, or if they had angiographically confirmed CAD that did not need revascularization. All 294 AFIRE study sites were in Japan.

The study’s primary endpoint for efficacy was a composite of stroke, systemic embolism, myocardial infarction, unstable angina requiring revascularization, and all-cause death.

Most of the patients (79%) were male, and the mean age was 74 years. About 70% of patients in each treatment arm had received prior PCI, and 11% had undergone previous coronary artery bypass grafting (CABG).

The monotherapy arm received rivaroxaban 10 or 15 mg once daily depending on renal status. Patients in the combination therapy arm received rivaroxaban, plus a single antiplatelet drug. This could be 81 or 100 mg aspirin daily, clopidogrel at 50 or 75 mg/day, or prasugrel at 2.5 or 3.5 mg/day.

On the recommendation of the data and safety monitoring committee, the trial was terminated about 3 months early because significantly more all-cause deaths were being seen in the combination therapy group, said Dr. Yasuda. In the end, patients were treated under the study protocol for a median 23 months and followed up for a median 24.1 months.

Kaplan-Meier estimates for the first occurrence of the composite efficacy endpoint showed that monotherapy had a rate of 4.14% per patient-year, while combination therapy had a rate of occurrence for the efficacy endpoint of 5.75% per patient-year.

These figures yielded a statistically significant hazard ratio (HR) of 9.72 favoring monotherapy (P less than .001) for the prespecified noninferiority endpoint. In a post hoc analysis, rivaroxaban monotherapy achieved superiority over dual therapy (P = .02).

Breaking down the composite efficacy endpoint into its constituents, deaths by any cause and cardiovascular deaths primarily drove the difference in treatment arms. Seventy-three patients in the combo therapy arm and 41 in the rivaroxaban arm died of any cause, and the cause of death was cardiovascular for 43 combination therapy patients and 26 monotherapy patients. This yielded HRs favoring rivaroxaban of 0.55 for all-cause mortality and 0.59 for cardiovascular deaths.

Hazard ratios for individual cardiovascular events were not statistically significantly different between treatment arms, except for hemorrhagic stroke, which was seen in 13 patients receiving dual therapy and 4 receiving rivaroxaban alone, for a hazard ratio of 0.30.

Rivaroxaban monotherapy also bested dual therapy in safety: The HR was 0.59 for the incidence of a major bleed on rivaroxaban versus combination therapy, using International Society on Thrombosis and Haemostasis–established criteria for major bleeding. In the dual therapy arm, 58 individuals experienced major bleeding – the study’s primary safety endpoint – compared with 35 in the monotherapy arm, for a hazard ratio of 0.59; nonmajor bleeding occurred in 198 dual therapy patients and 121 monotherapy patients, yielding a hazard ratio of 0.58.

The Kaplan-Meier estimate for major bleeding on monotherapy was 1.62% per patient-year, compared with 2.76% per patient-year for those on combination therapy. These findings, said Dr. Yasuda, were “generally” consistent across prespecified subgroups that included participant stratification by age, sex, and bleeding risk, among others.

Dr. Yasuda acknowledged the many limitations of the trial. First, early termination introduced the possibility of overestimating the benefit of rivaroxaban monotherapy. Indeed, said Dr. Yasuda, “the reductions in rate of ischemic events and death from any cause with rivaroxaban monotherapy were unanticipated and are difficult to explain.”

Furthermore, the open-label trial design could be a source of bias and the use of both aspirin and P2Y12 inhibitors for antiplatelet therapy “makes it uncertain whether the benefit of rivaroxaban monotherapy applies equally to the two combination regimens,” said Dr. Yasuda.

Rivaroxaban dosing in AFIRE was tailored to the Japanese study population, noted Dr. Yasuda. This means that the study is not immediately generalizable to non-Asian populations, needing replication before fully closing the knowledge gap about best long-term management of patients with AFib and stable CAD in the United States and Western Europe.

However, Dr. Yasuda pointed out, serum rivaroxaban levels in Japanese patients taking the 10- or 15-mg dose are generally similar to those seen in white patients taking a 20-mg rivaroxaban dose.

Freek Verheugt, MD, of Onze Lieve Vrouwe Gasthuis Hospital, Amsterdam, was the discussant for the presentation. He raised an additional concern: “East Asian patients are poor metabolizers of clopidogrel, which may have resulted also in underestimation of bleeding.” He cautioned that the AFIRE results may not be applicable to patients on a novel anticoagulant other than clopidogrel, or on vitamin K antagonists.

In his detailed critique of the AFIRE results, Dr. Verheugt cited the OAC ALONE trial, which used a similar study design and was also conducted in Japan. For OAC ALONE, Dr. Verheugt pointed out that “You can see ... that it was not harmful in this 700-patient study to stop aspirin therapy 1 year after an intervention.” However, he said, “the net clinical benefit is not very different, either” between treatment arms in the OAC ALONE trial. “Given the low number of patients and the low number of events, this trial was not conclusive whatsoever” he added, so AFIRE’s findings were needed.

The safety data from AFIRE, with a study population triple that of OAC ALONE, makes the safety argument for monotherapy “a very easy winner,” said Dr. Verheugt.

Dr. Verheugt was not mystified by the lower all-cause and cardiovascular death rate in the monotherapy group. “What are the mechanisms that if you stop antiplatelet therapy you have a better ischemic outcome? How come?” asked Dr. Verheugt.

“Very likely, it is the bleeding ... that you prevent if you stop antiplatelet therapy,” he said, adding that it’s known from previous studies in individuals with acute coronary syndromes and AFib that “bleeding is correlated with mortality, and that’s also proven here.”

Though Dr. Verheugt joined Dr. Yasuda in calling for replication of the results in a non-Asian population, he concurred that the AFIRE results validate current practice for anticoagulation in AFib with stable CAD. “Stopping at 1 year is safer than continuation and, most of all, it saves lives,” he said.

Full results of AFIRE were published online at the time of Dr. Yasuda’s presentation (N Engl J Med. 2019 Sep 2. doi: 10.1056/NEJMoa1904143).

PARIS – Rivaroxaban monotherapy bested combination therapy with rivaroxaban and an antiplatelet agent for patients with atrial fibrillation and stable coronary artery disease, with significantly more deaths and bleeding events seen with combination therapy.

Catherine Hackett/MDedge News

The pronounced imbalance in all-cause and cardiovascular mortality (the hazard ratio favoring rivaroxaban monotherapy was 9.72) came as a surprise, and led to early cessation of the multisite Japanese trial, lead investigator Satoshi Yasuda, MD, said at the annual congress of the European Society of Cardiology.

Several previous clinical trials had studied a reduced antithrombotic regimen for patients with atrial fibrillation (AFib) after percutaneous coronary intervention (PCI), said Dr. Yasuda, professor of medicine at Tohoku University, Sendai, Japan. Current guidelines recommend triple therapy with an oral anticoagulant plus aspirin and a P2Y12 inhibitor for the shortest duration possible, with combination therapy of an anticoagulant plus a P2Y12 inhibitor for up to 12 months. Once the 1-year post-PCI mark is reached, current European and American guidelines or consensus documents recommend monotherapy with an oral anticoagulant if AFib persists and the patient has stable coronary artery disease (CAD), explained Dr. Yasuda. “However, this approach has yet to be supported by evidence from randomized, controlled trials,” he said, adding “substantial numbers of patients in this situation continue to be treated with combination therapy, which indicates a gap between guidelines and clinical practice.”

The Atrial Fibrillation and Ischemic events with Rivaroxaban in Patients With Stable Coronary Artery Disease Study (AFIRE), he said, was designed to address this practice gap, randomizing 2,200 individuals to receive monotherapy with rivaroxaban or combination therapy. A total of 1,973 patients completed follow-up.

Patients were included in the randomized, open-label, parallel-group trial if they had AFib and stable CAD and were more than 1 year out from revascularization, or if they had angiographically confirmed CAD that did not need revascularization. All 294 AFIRE study sites were in Japan.

The study’s primary endpoint for efficacy was a composite of stroke, systemic embolism, myocardial infarction, unstable angina requiring revascularization, and all-cause death.

Most of the patients (79%) were male, and the mean age was 74 years. About 70% of patients in each treatment arm had received prior PCI, and 11% had undergone previous coronary artery bypass grafting (CABG).

The monotherapy arm received rivaroxaban 10 or 15 mg once daily depending on renal status. Patients in the combination therapy arm received rivaroxaban, plus a single antiplatelet drug. This could be 81 or 100 mg aspirin daily, clopidogrel at 50 or 75 mg/day, or prasugrel at 2.5 or 3.5 mg/day.

On the recommendation of the data and safety monitoring committee, the trial was terminated about 3 months early because significantly more all-cause deaths were being seen in the combination therapy group, said Dr. Yasuda. In the end, patients were treated under the study protocol for a median 23 months and followed up for a median 24.1 months.

Kaplan-Meier estimates for the first occurrence of the composite efficacy endpoint showed that monotherapy had a rate of 4.14% per patient-year, while combination therapy had a rate of occurrence for the efficacy endpoint of 5.75% per patient-year.

These figures yielded a statistically significant hazard ratio (HR) of 9.72 favoring monotherapy (P less than .001) for the prespecified noninferiority endpoint. In a post hoc analysis, rivaroxaban monotherapy achieved superiority over dual therapy (P = .02).

Breaking down the composite efficacy endpoint into its constituents, deaths by any cause and cardiovascular deaths primarily drove the difference in treatment arms. Seventy-three patients in the combo therapy arm and 41 in the rivaroxaban arm died of any cause, and the cause of death was cardiovascular for 43 combination therapy patients and 26 monotherapy patients. This yielded HRs favoring rivaroxaban of 0.55 for all-cause mortality and 0.59 for cardiovascular deaths.

Hazard ratios for individual cardiovascular events were not statistically significantly different between treatment arms, except for hemorrhagic stroke, which was seen in 13 patients receiving dual therapy and 4 receiving rivaroxaban alone, for a hazard ratio of 0.30.

Rivaroxaban monotherapy also bested dual therapy in safety: The HR was 0.59 for the incidence of a major bleed on rivaroxaban versus combination therapy, using International Society on Thrombosis and Haemostasis–established criteria for major bleeding. In the dual therapy arm, 58 individuals experienced major bleeding – the study’s primary safety endpoint – compared with 35 in the monotherapy arm, for a hazard ratio of 0.59; nonmajor bleeding occurred in 198 dual therapy patients and 121 monotherapy patients, yielding a hazard ratio of 0.58.

The Kaplan-Meier estimate for major bleeding on monotherapy was 1.62% per patient-year, compared with 2.76% per patient-year for those on combination therapy. These findings, said Dr. Yasuda, were “generally” consistent across prespecified subgroups that included participant stratification by age, sex, and bleeding risk, among others.

Dr. Yasuda acknowledged the many limitations of the trial. First, early termination introduced the possibility of overestimating the benefit of rivaroxaban monotherapy. Indeed, said Dr. Yasuda, “the reductions in rate of ischemic events and death from any cause with rivaroxaban monotherapy were unanticipated and are difficult to explain.”

Furthermore, the open-label trial design could be a source of bias and the use of both aspirin and P2Y12 inhibitors for antiplatelet therapy “makes it uncertain whether the benefit of rivaroxaban monotherapy applies equally to the two combination regimens,” said Dr. Yasuda.

Rivaroxaban dosing in AFIRE was tailored to the Japanese study population, noted Dr. Yasuda. This means that the study is not immediately generalizable to non-Asian populations, needing replication before fully closing the knowledge gap about best long-term management of patients with AFib and stable CAD in the United States and Western Europe.

However, Dr. Yasuda pointed out, serum rivaroxaban levels in Japanese patients taking the 10- or 15-mg dose are generally similar to those seen in white patients taking a 20-mg rivaroxaban dose.

Freek Verheugt, MD, of Onze Lieve Vrouwe Gasthuis Hospital, Amsterdam, was the discussant for the presentation. He raised an additional concern: “East Asian patients are poor metabolizers of clopidogrel, which may have resulted also in underestimation of bleeding.” He cautioned that the AFIRE results may not be applicable to patients on a novel anticoagulant other than clopidogrel, or on vitamin K antagonists.

In his detailed critique of the AFIRE results, Dr. Verheugt cited the OAC ALONE trial, which used a similar study design and was also conducted in Japan. For OAC ALONE, Dr. Verheugt pointed out that “You can see ... that it was not harmful in this 700-patient study to stop aspirin therapy 1 year after an intervention.” However, he said, “the net clinical benefit is not very different, either” between treatment arms in the OAC ALONE trial. “Given the low number of patients and the low number of events, this trial was not conclusive whatsoever” he added, so AFIRE’s findings were needed.

The safety data from AFIRE, with a study population triple that of OAC ALONE, makes the safety argument for monotherapy “a very easy winner,” said Dr. Verheugt.

Dr. Verheugt was not mystified by the lower all-cause and cardiovascular death rate in the monotherapy group. “What are the mechanisms that if you stop antiplatelet therapy you have a better ischemic outcome? How come?” asked Dr. Verheugt.

“Very likely, it is the bleeding ... that you prevent if you stop antiplatelet therapy,” he said, adding that it’s known from previous studies in individuals with acute coronary syndromes and AFib that “bleeding is correlated with mortality, and that’s also proven here.”

Though Dr. Verheugt joined Dr. Yasuda in calling for replication of the results in a non-Asian population, he concurred that the AFIRE results validate current practice for anticoagulation in AFib with stable CAD. “Stopping at 1 year is safer than continuation and, most of all, it saves lives,” he said.

Full results of AFIRE were published online at the time of Dr. Yasuda’s presentation (N Engl J Med. 2019 Sep 2. doi: 10.1056/NEJMoa1904143).

STOCKHOLM – Just under half of a small cohort of patients with multiple sclerosis (MS) who discontinued disease modifying therapy (DMT) showed signs of relapse or disease progression on magnetic resonance imaging (MRI). Patients who were younger had a higher probability of relapse, according to data presented at the annual congress of the European Committee for Treatment and Research in Multiple Sclerosis.

Of 49 patients who had been on DMT for at least 5 years and had shown no evidence of disease activity (NEDA) during that time, 26 continued to have NEDA through at least 5 years of follow-up, explained Tobias Monschein, MD, of the department of neurology at the Medical University of Vienna.

The cohort of patients had all been taking either interferon beta or glatiramer acetate after a first clinical episode leading to an initial diagnosis of MS. Patients all met Barkhof criteria for MS diagnosis on MRI, and all but six patients had oligoclonal bands found on examination of cerebrospinal fluid.

All patients in the cohort thus met criteria for clinically isolated syndrome (CIS) and MS under the 2017 revisions to the McDonald diagnostic criteria. “To our knowledge, this is the first study determining the risk of disease recurrence in a homogenous cohort of patients with CIS,” reported Dr. Monschein and collaborators.

Before stopping DMT, patients had to show at least 5 years of NEDA status; at that point, patients were offered the opportunity to discontinue medication. The decision to stop or continue taking a DMT was left to individual patient choice, Dr. Monschein said in an interview.

The cohort of patients who decided to discontinue DMT was seen yearly; they received a clinical examination that included expanded disability status scale (EDSS) rating. Patients also received an annual MRI.

Age at DMT discontinuation was predictive of remaining disease free, found Dr. Monschein and collaborators. The 26 patients who continued disease free after DMT discontinuation were a mean 29.7 years old, while patients who had disease recurrence were a mean 22.7 years old.

Looking at age as a dichotomous variable, the investigators found that the 16 patients who were 40 years or older when they stopped DMT had an 18.8% risk of MS recurrence, while the 33 patients younger than 40 years at the time of ceasing DMT had a 60.6% risk of recurrence.

Age, in fact, was the only patient, disease, or therapy characteristic that Dr. Monschein and colleagues found predictive of relapse: “Gender, type of DMT, treatment duration, and CIS symptom did not differ significantly between groups,” they reported.

The data “should not encourage patients to generally stop DMTs after a long NEDA period,” they noted.

In the context of shared patient decision-making, though, the data can inform discussion with patients who wish to discontinue DMTS after long disease-free periods, Dr. Monschein said.

“Physicians should encourage younger people to stay on DMTS despite long lasting NEDA status while in patients [older than] 40 years stopping DMTs together with regular clinical and radiological monitoring could be a reasonable option,” he and his colleagues advised.

Dr. Monschein reported no outside sources of funding and no conflicts of interest.

STOCKHOLM – Inebilizumab, a medication being developed to treat neuromyelitis optica spectrum disorder (NMO/NMOSD), fared well against placebo in a randomized trial, according to recently presented results.

Participants in the active arm of the study saw a 77% relative reduction in the risk of an attack of NMO, compared with placebo, for a number needed to treat of 3.2 to see benefit from inebilizumab, said senior investigator Bruce Cree, MD, PhD.

The multisite, international N-MOmentum study compared inebilizumab, a B-cell depleting humanized monoclonal antibody, with placebo as monotherapy for the treatment of NMOSD. The results were presented at the annual congress of the European Committee for Treatment and Research in Multiple Sclerosis.

Adult patients with NMOSD were eligible if they had experienced at least one attack in the previous year, or at least two attacks in the previous 2 years, and had an Expanded Disability Status Scale (EDSS; range, 0-10; 0, normal) score of 8 or less, Dr. Cree said. Diagnostic criteria for study participation were either seropositivity for aquaporin 4-IgG or fulfillment of the 2006 Wingerchuk criteria for NMOSD if individuals were aquaporin 4-IgG negative.

Patients were about 43 years old at enrollment. More than 90% were women, and about three-quarters were white or Asian. The baseline EDSS score was about 3.5, and patients had experienced a mean of just over four attacks on study entry. The full cohort of patients was over 90% seropositive, and about 60% had been on prior immunosuppressive therapy.

“This was a monotherapy study, meaning that no background immunotherapy was permitted,” said Dr. Cree, the George A. Zimmermann Endowed Professor in Multiple Sclerosis in the department of neurology at the University of California, San Francisco. Patients were randomized 3:1 to receive either two 300-mg doses of inebilizumab by intravenous infusion on study days 1 and 13 or matched placebo infusions.

“When we think about B cells and NMO, multiple lines of evidence have suggested that NMO is a B-cell–mediated disorder resulting from pathogenic antibody production, pro-inflammatory cytokine secretion, and antigen presentation by B cells,” he explained, adding that inebilizumab targets the cell surface antigen, CD19, which is expressed “perhaps more widely than CD20.”

The randomized, double-blind, placebo-controlled phase 2/3 study was followed by an open-label extension period. “This was a time-to-event study design,” Dr. Cree explained, with the randomized period limited to 197 days. After that period, participants could enroll in the open-label extension arm and receive active treatment for at least 1 year. “In the event that a participant experienced an attack during the course of the study that was an adjudicated attack, they were pulled out and offered entry into the open-label period shortly after the attack,” he added.

Adjudicated attacks were the study’s primary endpoint, measured as the time from study day 1 to an adjudicated attack for patients in the randomized population. Dr. Cree said that study development included identifying 18 “predefined, clinically significant” attack diagnosis criteria. These included attacks of optic myelitis, neuritis, and brain-stem events.

Of the 18 criteria, 10 constituted overt clinical changes and the remaining 8 represented more moderate clinical changes that had to be accompanied by a new lesion detected on MRI. All criteria required confirmation by the adjudication committee to qualify as an attack.

By study day 197, 18 of 161 participants (11.2%) of those remaining in the randomized study arm had experienced an adjudicated NMOSD attack, compared with 22 of 52 (42.3%) of those still in the placebo arm. That drop translated into a relative risk reduction of 77.3% and a hazard ratio of 0.227 for NMOSD attack favoring inebilizumab (P less than .0001).

“That risk of attack [for participants in the inebilizumab arm] continued to be low following entry into the open-label extension, whereas patients who were initially treated with placebo experienced some attacks initially, and that looked like it began to flatten out as well” during the open-label extension arm, said Dr. Cree.

Secondary endpoints included worsening of EDSS scores, changes in low-contrast visual acuity binocular score, the cumulative number of active MRI lesions, and hospitalizations deemed to be NMOSD related. Participants receiving inebilizumab saw significant reductions in all of these endpoints except for the visual acuity measure, with no differences seen in outcomes for seropositive versus seronegative participants.

A total of 231 patients were randomized, with the eventual intention-to-treat population including 174 inebilizumab patients and 56 in the placebo arm (one patient was randomized to inebilizumab but never received a dose of study drug). All but five inebilizumab patients and two placebo patients completed the study. The independent data-monitoring committee recommended stopping enrollment in the randomized phase of the study at 231 patients for efficacy, even though there had been only 43 adjudicated attacks at that point, Dr. Cree explained.

The medication was generally well tolerated. Urinary tract infection – the most common adverse event – was experienced by 22% of patients. Infusion site reactions were more common in those receiving placebo than in those receiving inebilizumab, he noted.

Over the two total years of inebilizumab exposure to date, there have been two deaths. One was related to a severe NMO attack and the other to “an event of undetermined etiology due to a presumed inflammatory brain lesion,” Dr. Cree said, adding that “no autopsy or biopsy was performed, unfortunately.”

The investigators tracked IgG levels over the course of the study and noted that they continued to decline over the course of the study, with 14% of patients having a level less than the lower limit of normal at the 2-year mark. This suggests that IgG levels will have to be followed for patients taking the drug over the long term, he said.

Serum glial fibrillary acidic protein, a serum marker of astroglial injury, is ordinarily elevated during NMOSD attacks. For participants on inebilizumab who experienced attacks, elevations in glial fibrillary acidic protein were not as marked, which suggests that the severity of tissue injury in an attack may be attenuated by the drug, said Dr. Cree.

The study was funded by Viela Bio and Medimmune, which are developing inebilizumab. Viela Bio also funded medical writing for the presentation. Dr. Cree reported receiving consulting fees from Abbvie, Akili, Alexion, Biogen, GeNeuro, Novartis, Sanofi Genzyme, and TG Therapeutics.

STOCKHOLM – Inebilizumab, a medication being developed to treat neuromyelitis optica spectrum disorder (NMO/NMOSD), fared well against placebo in a randomized trial, according to recently presented results.

Participants in the active arm of the study saw a 77% relative reduction in the risk of an attack of NMO, compared with placebo, for a number needed to treat of 3.2 to see benefit from inebilizumab, said senior investigator Bruce Cree, MD, PhD.

The multisite, international N-MOmentum study compared inebilizumab, a B-cell depleting humanized monoclonal antibody, with placebo as monotherapy for the treatment of NMOSD. The results were presented at the annual congress of the European Committee for Treatment and Research in Multiple Sclerosis.

Adult patients with NMOSD were eligible if they had experienced at least one attack in the previous year, or at least two attacks in the previous 2 years, and had an Expanded Disability Status Scale (EDSS; range, 0-10; 0, normal) score of 8 or less, Dr. Cree said. Diagnostic criteria for study participation were either seropositivity for aquaporin 4-IgG or fulfillment of the 2006 Wingerchuk criteria for NMOSD if individuals were aquaporin 4-IgG negative.

Patients were about 43 years old at enrollment. More than 90% were women, and about three-quarters were white or Asian. The baseline EDSS score was about 3.5, and patients had experienced a mean of just over four attacks on study entry. The full cohort of patients was over 90% seropositive, and about 60% had been on prior immunosuppressive therapy.

“This was a monotherapy study, meaning that no background immunotherapy was permitted,” said Dr. Cree, the George A. Zimmermann Endowed Professor in Multiple Sclerosis in the department of neurology at the University of California, San Francisco. Patients were randomized 3:1 to receive either two 300-mg doses of inebilizumab by intravenous infusion on study days 1 and 13 or matched placebo infusions.

“When we think about B cells and NMO, multiple lines of evidence have suggested that NMO is a B-cell–mediated disorder resulting from pathogenic antibody production, pro-inflammatory cytokine secretion, and antigen presentation by B cells,” he explained, adding that inebilizumab targets the cell surface antigen, CD19, which is expressed “perhaps more widely than CD20.”

The randomized, double-blind, placebo-controlled phase 2/3 study was followed by an open-label extension period. “This was a time-to-event study design,” Dr. Cree explained, with the randomized period limited to 197 days. After that period, participants could enroll in the open-label extension arm and receive active treatment for at least 1 year. “In the event that a participant experienced an attack during the course of the study that was an adjudicated attack, they were pulled out and offered entry into the open-label period shortly after the attack,” he added.

Adjudicated attacks were the study’s primary endpoint, measured as the time from study day 1 to an adjudicated attack for patients in the randomized population. Dr. Cree said that study development included identifying 18 “predefined, clinically significant” attack diagnosis criteria. These included attacks of optic myelitis, neuritis, and brain-stem events.

Of the 18 criteria, 10 constituted overt clinical changes and the remaining 8 represented more moderate clinical changes that had to be accompanied by a new lesion detected on MRI. All criteria required confirmation by the adjudication committee to qualify as an attack.

By study day 197, 18 of 161 participants (11.2%) of those remaining in the randomized study arm had experienced an adjudicated NMOSD attack, compared with 22 of 52 (42.3%) of those still in the placebo arm. That drop translated into a relative risk reduction of 77.3% and a hazard ratio of 0.227 for NMOSD attack favoring inebilizumab (P less than .0001).

“That risk of attack [for participants in the inebilizumab arm] continued to be low following entry into the open-label extension, whereas patients who were initially treated with placebo experienced some attacks initially, and that looked like it began to flatten out as well” during the open-label extension arm, said Dr. Cree.

Secondary endpoints included worsening of EDSS scores, changes in low-contrast visual acuity binocular score, the cumulative number of active MRI lesions, and hospitalizations deemed to be NMOSD related. Participants receiving inebilizumab saw significant reductions in all of these endpoints except for the visual acuity measure, with no differences seen in outcomes for seropositive versus seronegative participants.

A total of 231 patients were randomized, with the eventual intention-to-treat population including 174 inebilizumab patients and 56 in the placebo arm (one patient was randomized to inebilizumab but never received a dose of study drug). All but five inebilizumab patients and two placebo patients completed the study. The independent data-monitoring committee recommended stopping enrollment in the randomized phase of the study at 231 patients for efficacy, even though there had been only 43 adjudicated attacks at that point, Dr. Cree explained.

The medication was generally well tolerated. Urinary tract infection – the most common adverse event – was experienced by 22% of patients. Infusion site reactions were more common in those receiving placebo than in those receiving inebilizumab, he noted.

Over the two total years of inebilizumab exposure to date, there have been two deaths. One was related to a severe NMO attack and the other to “an event of undetermined etiology due to a presumed inflammatory brain lesion,” Dr. Cree said, adding that “no autopsy or biopsy was performed, unfortunately.”

The investigators tracked IgG levels over the course of the study and noted that they continued to decline over the course of the study, with 14% of patients having a level less than the lower limit of normal at the 2-year mark. This suggests that IgG levels will have to be followed for patients taking the drug over the long term, he said.

Serum glial fibrillary acidic protein, a serum marker of astroglial injury, is ordinarily elevated during NMOSD attacks. For participants on inebilizumab who experienced attacks, elevations in glial fibrillary acidic protein were not as marked, which suggests that the severity of tissue injury in an attack may be attenuated by the drug, said Dr. Cree.

STOCKHOLM – Among a cohort of patients with highly active multiple sclerosis (MS), MRI without gadolinium contrast still detected most lesions. Further, lesions missed by skipping gadolinium would have changed treatment course for just 1 of the 84 patients in the study, said Lucia Gentili, MD, a neurologist in the department of medicine, section of neurology, at the University of Perugia (Italy), in an interview at the annual congress of the European Committee on Treatment and Research in Multiple Sclerosis.

“Postcontrast MRI might not be mandatory to detect signs of disease activity in patients with active MS,” she observed.

The question of the long-term effects of gadolinium deposition from serial scans in patients with MS is a hot topic among both patients and those caring for people with MS, said Dr. Gentili, so she and her associates decided to see how avoiding gadolinium exposure would affect lesion detection and patient management among their patient population.

For the retrospective study, the investigators looked at the records of 84 patients with relapsing remitting MS at two Italian MS centers over a 5-year time span. This was a cohort enriched for patients with highly active disease, said Dr. Gentili. A total of 45 patients, or over half of the cohort, had experienced at least one relapse in the preceding year.

The study included patients who were being screened for a second-line treatment and had evidence of brain or spinal cord contrast-enhancing lesions on MRI, if they also had a previous MRI of the brain and spinal cord performed on the same scanner.

The uniform protocol used for all MRIs included axial T2-weighted, fluid attenuated inversion recovery (FLAIR), and pre- and postcontrast T1-weighted sequences.

In all, the reference MRI scans picked up 164 contrast-enhancing lesions; of these, 151 (92.1%) were also seen on the T2/FLAIR sequences, showing up as new or enlarging lesions. Thirteen lesions were not visible on T2/FLAIR sequences when compared with the previous MRI, said Dr. Gentili.

Almost all patients in the cohort – a group with highly active disease, Dr. Gentili emphasized – also had new or enlarging lesions visible in T2 sequences. “Only two patients with MRI evidence of contrast-enhancing lesions showed no new or enlarged lesions in T2/FLAIR images,” she added. “Therefore, without gadolinium administration, only two patients in our cohort would have been incorrectly classified as radiologically stable.”

In reality, though, one of the two subjects whose disease activity was missed without gadolinium contrast had a relapse in the preceding 12 months, so clinical evidence of disease activity prompted attention to this individual. “Thus, only one subject in the entire cohort would have been incorrectly classified as stable,” Dr. Gentili and coauthors reported.

The results of this small study do not represent a case for abandoning gadolinium, Dr. Gentili stressed. “In our study, active lesions detected only by gadolinium enhancement, that is, without any evidence of new or enlarged lesions on T2/FLAIR, occurred in a limited but significant portion of contrast-enhancing lesions,” occurring in about 8% of the total lesions.

Rather, this study and other ongoing work represents a basis for shared decision making between persons with MS and those caring for them. Particularly for patients with highly active MS who can anticipate receiving a high burden of contrast to track disease activity, physicians can consider presenting them with the option to omit gadolinium contrast, she said.

Dr. Gentili reported receiving a travel grant from the ECTRIMS scientific program committee, and several coauthors reported relationships with multiple pharmaceutical companies. One coauthor received research funding from the Italian Multiple Sclerosis Society, the Italian Ministry of health, and the Italian Ministry of Education.

STOCKHOLM – The presence of an iron ring around a brain lesion suspicious for multiple sclerosis (MS) may provide a promising adjunct to evolving magnetic resonance imaging techniques to track disease activity and progression, according to research presented at the annual congress of the European Committee for Treatment and Research in Multiple Sclerosis.

Kari Oakes/MDedge News

Using a conventional 3 Tesla magnetic resonance imaging (MRI) scanner, Margareta Clarke, PhD, and colleagues were able to identify iron rings (also called iron rims) and the central vein sign, and saw that both lesion characteristics were more common in MS patients than in those without MS.

“Routine two-dimensional 3 Tesla MRI with susceptibility weighting can be used to successfully visualize central veins and iron rims,” said Dr. Clarke, speaking at an imaging-focused young investigators’ session at the meeting. “Also, the central vein sign findings from previous 3T studies are confirmed.”

Dr. Clarke, a research fellow at the Vall d’Hebron Research Institute in Barcelona, explained that iron is stored within oligodendrocytes and myelin within the brain. In up to 56% of MS lesions, a rim of iron is visible with susceptibility weighted MRI imaging, she said, adding that the iron rings around the lesions “are likely caused by iron-laden activated microglia and macrophages that accumulate on the edges of lesions.”

It had been known that when lesions are surrounded by iron rings, they are more likely to enlarge and become increasingly hypointense on T1 weighted MRI. In addition, patients with more disability are more likely to have iron-rimmed brain lesions, said Dr. Clarke, and iron rings are associated with chronic disease activity. “Iron rings are a proposed marker of continuing inflammation and tissue loss,” she added.

NEW YORK – Inpatient dermatology consults can make all the difference when a serious dermatology complication is suspected, said Lucia Seminario-Vidal, MD, PhD, speaking at a hospital dermatology–focused session of the summer meeting of the American Academy of Dermatology.

Even before histopathologic results are available, dermatologists can help take some of the panic out of the room when Stevens-Johnson syndrome or toxic epidermal necrolysis (SJS/TEN) is first on the differential diagnosis for the referring physician, she said. Physical findings, a careful review of systems, and past history – especially the introduction of any new medications – can go a long way toward ruling out SJS/TEN among many patients.

In a recent study coauthored by Dr. Seminario-Vidal, of the University of South Florida, Tampa, 208 inpatients with suspected SJS/TEN, 72% were given another diagnosis after a dermatologist consultation (J Am Acad Dermatol. 2019 Sep;81[3]:749-57). The study’s authors, led by Allison Weinkle, MD, a dermatology resident at the University of South Florida, performed a retrospective chart review of 208 patients suspected of having SJS/TEN and received inpatient dermatology consultations.

One surprising finding from the review is that “known risk factors for SJS/TEN such as drug exposure, malignancy, and HIV/AIDS are not helpful to differentiate it from its mimickers,” Dr. Seminario-Vidal said.

However, close attention to the clinical presentation is helpful in differentiating the mimickers from true SJS/TEN. Fever, painful skin, Nikolsky sign, and mucosal involvement were all more common in patients with SJS/TEN. “This was something that was really helpful to discuss with the primary teams at our institutions,” Dr. Seminario-Vidal said.

The most common mimickers in the cases she and her colleagues reviewed were severe cutaneous adverse drug reactions (SCARs) and erythema multiforme; in general, the mimickers were conditions that have severe mucocutaneous involvement.

Patients with SJS/TEN will have fever and pain, typically, and the primary lesions are atypical targets with a positive Nikolsky sign. Hepatic enzyme elevation is seen in 15% of patients, and lymphopenia may be present. Common drugs provoking SJS/TEN include antibiotics, anticonvulsants, NSAIDs, allopurinol, and – importantly – programmed cell death protein 1 (PD-1) inhibitors. Because PD-1s are being used for an ever-expanding range of oncology indications, the rate of SJS/TEN may be expected to rise, Dr. Seminario-Vidal noted.

Other common mimics can include a florid generalized fixed drug eruption, which can also be painful and have atypical targets and a positive Nikolsky sign. Here, large, dusky patches may be present, with perioral, genital, and hand/foot involvement common, but fever is absent. Lesions are sharply localized, round or oval, and they recur at the same site with reexposure to the provoking agent. “Histopathologic studies are diagnostic in these patients, but many times, if you have a good clinical history, you don’t need histopathology,” Dr. Seminario-Vidal said.

As with SJS/TEN, mucosal involvement can be present with fixed drug eruptions. However, hepatic enzymes and the complete blood count will not show abnormalities related to the fixed drug eruption.

Sulfonamides have been associated with up to 75% of fixed drug eruptions reported in some case series, she said, noting that common over-the-counter medications such as nonprescription analgesics, loratadine, and pseudoephedrine can also provoke fixed drug eruptions.

Bullous conditions that can mimic SJS/TEN include linear Immunoglobulin A bullous dermatosis. “We know that the classic presentation is the beautiful ‘string of pearls’ sign, but most patients won’t have this,” Dr. Seminario-Vidal said. The condition often appears in intertriginous locations, and Koebnerization can be a strong clue to this diagnosis, she added.

This painful condition rarely has an associated fever, and will occasionally involve the mucosa, but it doesn’t cause alterations in laboratory values. About 70% of cases of drug-induced linear IgA bullous dermatosis are caused by vancomycin, a consideration when patients may be on several antibiotics. “When I first started, I used to stop everything,” said Dr. Seminario-Vidal. Now, she first discontinues vancomycin and rechecks the patient the next day. In the absence of progression, vancomycin can be presumed to be the culprit, she said.

In bullous pemphigoid, mucosal involvement has been reported in up to 30% of patients, which can initially confuse the diagnosis. “A clue is the presence of tense bullae that initially are very pruritic, but they can become painful over time,” Dr. Seminario-Vidal said. “With tense bullae, with no specific primary lesion, but the patient is very itchy, think bullous pemphigoid.” Pain is sometimes present, but fever is rare. Eosinophilia occurs about 50% of the time, offering an additional diagnostic clue.

Furosemide is a common culprit in drug-induced bullous pemphigoid, as is its cousin bumetanide. Certain analgesics, amoxicillin, ciprofloxacin, and angiotensin converting enzyme inhibitors have also been implicated, said Dr. Seminario-Vidal, though most cases are not drug induced. “Go over the drug history of the patients. It’s something that I cannot emphasize enough … because if you find the drug that causes this disease, you can avoid lengthy systemic treatment.”

Pemphigus foliaceus has a characteristic crusting scale that forms with the rupture of flaccid bullae. Nikolsky’s sign is positive. Mucosal involvement is rare, but is sometimes seen on the occasions when the condition is drug-induced, and laboratory values are usually normal, she said. “The clues to diagnosis of these patients are involvement in the seborrheic areas, including the face; there’s a lot of crust in pemphigus foliaceus.”

Drug-induced pemphigus foliaceus is associated with drugs that have a thiol group, or with sulfur groups that are converted to thiol (–SH) groups. These include both angiotensin converting enzyme inhibitors and angiotensin receptor blockers, penicillins, cephalosporins, and piroxicam. However, said Dr. Seminario-Vidal, penicillamine alone accounts for 50% of drug-induced pemphigus foliaceus.

Dr. Seminario-Vidal reported financial relationships with Eli Lilly, Soligenix, Helsinn, Eisai, Boehringer Ingelheim, Corrona, Akros, Novartis, AbbVie, BMS, Celgene, Glenmark, and Kyowa Kirin.

NEW YORK – Inpatient dermatology consults can make all the difference when a serious dermatology complication is suspected, said Lucia Seminario-Vidal, MD, PhD, speaking at a hospital dermatology–focused session of the summer meeting of the American Academy of Dermatology.

Even before histopathologic results are available, dermatologists can help take some of the panic out of the room when Stevens-Johnson syndrome or toxic epidermal necrolysis (SJS/TEN) is first on the differential diagnosis for the referring physician, she said. Physical findings, a careful review of systems, and past history – especially the introduction of any new medications – can go a long way toward ruling out SJS/TEN among many patients.

In a recent study coauthored by Dr. Seminario-Vidal, of the University of South Florida, Tampa, 208 inpatients with suspected SJS/TEN, 72% were given another diagnosis after a dermatologist consultation (J Am Acad Dermatol. 2019 Sep;81[3]:749-57). The study’s authors, led by Allison Weinkle, MD, a dermatology resident at the University of South Florida, performed a retrospective chart review of 208 patients suspected of having SJS/TEN and received inpatient dermatology consultations.

One surprising finding from the review is that “known risk factors for SJS/TEN such as drug exposure, malignancy, and HIV/AIDS are not helpful to differentiate it from its mimickers,” Dr. Seminario-Vidal said.

However, close attention to the clinical presentation is helpful in differentiating the mimickers from true SJS/TEN. Fever, painful skin, Nikolsky sign, and mucosal involvement were all more common in patients with SJS/TEN. “This was something that was really helpful to discuss with the primary teams at our institutions,” Dr. Seminario-Vidal said.

The most common mimickers in the cases she and her colleagues reviewed were severe cutaneous adverse drug reactions (SCARs) and erythema multiforme; in general, the mimickers were conditions that have severe mucocutaneous involvement.

Patients with SJS/TEN will have fever and pain, typically, and the primary lesions are atypical targets with a positive Nikolsky sign. Hepatic enzyme elevation is seen in 15% of patients, and lymphopenia may be present. Common drugs provoking SJS/TEN include antibiotics, anticonvulsants, NSAIDs, allopurinol, and – importantly – programmed cell death protein 1 (PD-1) inhibitors. Because PD-1s are being used for an ever-expanding range of oncology indications, the rate of SJS/TEN may be expected to rise, Dr. Seminario-Vidal noted.

Other common mimics can include a florid generalized fixed drug eruption, which can also be painful and have atypical targets and a positive Nikolsky sign. Here, large, dusky patches may be present, with perioral, genital, and hand/foot involvement common, but fever is absent. Lesions are sharply localized, round or oval, and they recur at the same site with reexposure to the provoking agent. “Histopathologic studies are diagnostic in these patients, but many times, if you have a good clinical history, you don’t need histopathology,” Dr. Seminario-Vidal said.

As with SJS/TEN, mucosal involvement can be present with fixed drug eruptions. However, hepatic enzymes and the complete blood count will not show abnormalities related to the fixed drug eruption.

Sulfonamides have been associated with up to 75% of fixed drug eruptions reported in some case series, she said, noting that common over-the-counter medications such as nonprescription analgesics, loratadine, and pseudoephedrine can also provoke fixed drug eruptions.

Bullous conditions that can mimic SJS/TEN include linear Immunoglobulin A bullous dermatosis. “We know that the classic presentation is the beautiful ‘string of pearls’ sign, but most patients won’t have this,” Dr. Seminario-Vidal said. The condition often appears in intertriginous locations, and Koebnerization can be a strong clue to this diagnosis, she added.

This painful condition rarely has an associated fever, and will occasionally involve the mucosa, but it doesn’t cause alterations in laboratory values. About 70% of cases of drug-induced linear IgA bullous dermatosis are caused by vancomycin, a consideration when patients may be on several antibiotics. “When I first started, I used to stop everything,” said Dr. Seminario-Vidal.

PARIS – In rural Peru, a comprehensive community-wide strategy to replace conventional table salt with a formulation that was 25% potassium chloride halved incident hypertension, also dropping blood pressure in participants with baseline hypertension.

The multifaceted intervention targeted six villages at the far north of Peru, replacing table salt with the lower-sodium substitute, J. Jaime Miranda, MD, PhD, said at a prevention-focused, late-breaking research session at the annual congress of the European Society of Cardiology. The 75/25 mixture had a palatable proportion of potassium, and was easily produced by combining table salt with potassium chloride crystals.

Dr. Miranda, director of the CRONICAS Center of Excellence at the Cayetano Heredia Peruvian University, Lima, and colleagues enrolled virtually all adult residents of the six villages in the study; patients who reported heart disease or chronic kidney disease were excluded.

“We wanted to achieve and shape a pragmatic study – and a pragmatic study that incorporates day-to-day behavior. We eat every day, but we think very little of our salt habits,” said Dr. Miranda in a video interview.

In all, 2,376 of 2,605 potential participants enrolled in the study, which used a stepped-wedge, cluster-randomized, controlled trial design. To track the primary outcome measures of systolic and diastolic BP, measurements were obtained every 5 months for a total of seven rounds of measurement, said Dr. Miranda.

Dr. Miranda said that the investigators borrowed principles from social marketing to ensure community-wide replacement of table salt with the low-sodium substitute. This meant that they branded and packaged the low-sodium salt and gave it to participants at no cost – but with a catch. To receive the low-sodium salt, participants had to turn in their table salt.

The effort was supported by promotional events and a trained “sales force” who brought messaging to families, restaurants, and key voices in the community. The attractively packaged replacement salt was distributed with a similarly branded shaker. “We wanted to guarantee the full replacement of salt in the entire village,” explained Dr. Miranda.

At the end of the study, individuals with hypertension saw a decrease in systolic BP of 1.92 mm Hg (95% confidence interval, –3.29 to –0.54).

New hypertension diagnoses, a secondary outcome measure, fell by 55% in participating villages; the hazard ratio for hypertension incidence was 0.45 (95% CI, 0.31-0.66) in a fully adjusted statistical model that accounted for clustering at the village level, as well as age, sex, education, wealth index, and body mass index, said Dr. Miranda.

Older village residents with hypertension saw greater BP reduction; for those aged at least 60 years, the mean reduction was 2.17 mm Hg (95% CI, –3.67 to –0.68).

The positive findings were met with broad applause during his presentation, a response that made his 15-hour trip from Lima to Paris worthwhile, said Dr. Miranda.

Adherence was assessed by obtaining 24-hour urine samples from a random sample of 100 participants before and after the study. “This was my biggest fear – that as soon as we left the door, people would go and throw it away,” said Dr. Miranda. Among these participants, excreted potassium rose, indicating adherence, but sodium stayed basically the same. Possible explanations included that individuals were adding table salt to their diets, or that other prepared foods or condiments contained high amounts of sodium.

The study shows the feasibility of a community-wide intervention that achieved the dual aims of population-wide reductions in BP and reduction in incident BP, and of achieving clinically meaningful benefits for the high-risk population, said Dr. Miranda. He remarked that the population was young overall, with a mean age of 43 years and a low mean baseline systolic BP of 113, making the modest population-wide reduction more notable.

“We wanted to shift the entire distribution of blood pressure in the village. And with that, we see gains not only in public health, but also effective improvements in blood pressure in those at high risk, particularly those who tend to have high blood pressure,” said Dr. Miranda.

Discussant Bruce Neal, MD, professor of medicine at the University of Sydney and senior director of the George Institute for Global Health in Newtown, Australia, congratulated Dr. Miranda and colleagues on accomplishing “a truly enormous project.” He began by noting that, though the reductions were modest, “the low starting blood pressures were almost certainly responsible for the magnitude of effect seen in this study.” He added that “this is nonetheless a worthwhile blood pressure reduction, particularly if it was sustained throughout life.”

Addressing the lack of decrease in excreted urine sodium, Dr. Neal noted that participants may have supplemented their diet with additional sodium by one means or another, “which might also have attenuated the blood pressure difference – but it could also reflect the challenges of measuring sodium and potassium effectively with 24-hour urine samples, which are difficult to collect.”

The lack of adverse effects was notable, said Dr. Neal. “When considering the use of salt substitute at the population level, the first question that arises is: ‘What about the risks of hyperkalemia?’

“I think those risks are probably greatly overstated,” he said, noting that only individuals with severe chronic kidney disease would likely be affected, and those individuals are already well versed on the importance of avoiding excess dietary potassium.

The study was funded by the National Institutes of Health through the Global Alliance for Chronic Disease program. Dr. Miranda reported that he had no conflicts of interest. Dr. Neal reported that he has financial relationships with Nu-Tec Salt and a Beijing-based salt manufacturer, related to research into salt substitutes.

PARIS – For patients with peripheral artery disease, statin therapy is a literal lifeline, nearly halving mortality risk, according to new research presented at the annual congress of the European Society of Cardiology.

Patients with peripheral manifestations of cardiovascular disease “are a population with an extremely high risk to suffer a heart attack or a stroke,” said Joern Dopheide, MD, during a press conference at the meeting. Despite the known benefits of statins, including the reduction of all-cause and cardiovascular death and the reduction of morbidity, adherence to guideline-directed statin therapy is far from optimal, said Dr. Dopheide of Bern (Switzerland) University Hospital.

Patients with peripheral artery disease (PAD) not taking statins had a mortality rate of 34%, more than three times that of patients adherent to an intensified statin regimen. More surprisingly, patients who had been on a statin and then stopped the medication also had a mortality rate of 33%, indistinguishable from those who had never been treated with a statin.

Although statin adherence is low in general, it’s especially low in patients with PAD, said Dr. Dopheide. Still, he said, “few systematic data exist on the prognostic value of statin adherence and the correlation between adherence and cardiovascular outcome in PAD patients.”

Accordingly, Dr. Dopheide and his coinvestigators sought to determine the association between statin adherence and survival in PAD patients. The researchers obtained baseline and follow-up data for a cohort of 691 symptomatic PAD patients seen at a single site, looking at statin dosage, LDL cholesterol levels, and survival.

The patients were followed for a period of 50 months. Dr. Dopheide said that “Over the time course, we were able to increase the statin adherence from about 73% to about 81%, and parallel to that, we were able to reduce the LDL cholesterol levels from about 97 to 83 mg/dL, and we were able to increase the intensity of patients on statin therapy.”

Dr. Dopheide said that he and his colleagues saw a dose-response effect, so that the biggest drop in cholesterol was seen in patients on high statin doses, on more potent statins, or both.

Intensity was increased in some cases by upping statin dose – the mean statin dose climbed from 50 to 58 mg daily during the study period. An alternative strategy was to switch to a more potent statin such as atorvastatin or rosuvastatin; sometimes both intensity and dose were boosted.

“We were able to see that patients who were always on their statin therapy had a pretty low mortality rate of about 20%,” a figure that was halved for patients on more intensive statin therapy, who had a mortality rate of 10% across the study period, said Dr. Dopheide. “Patients in whom we started a statin therapy still profited from it, and had only a 15% mortality,” he added.

Some of the most surprising – and disturbing – study findings involved those who reduced their statin dose: “When patients discontinued their usual dose and decreased it, they suffered an even higher mortality rate, of nearly 43%. So that was kind of surprising and shocking to us.”

Identifying these high-risk patients and keeping them adherent is a substantial clinical challenge, but an important goal, said Dr. Dopheide. “We know that patients with peripheral arterial disease are a little more underrepresented in daily practice; it’s hard to identify them, especially when they are asymptomatic,” he acknowledged. However, once a PAD patient is identified, “One should at least keep the patient on the statin dosage they have,” or initiate statins if needed.

Further, warned Dr. Dopheide, “One should never discontinue statin or decrease the dosage,” adding that PAD patients should be informed that they are at “very high risk for myocardial infarction or stroke.” These patients “should regard their statin therapy as one of the most important and life-saving medications they can take,” he said.

Dr. Dopheide reported no outside sources of funding and no conflicts of interest.

PARIS – For patients with peripheral artery disease, statin therapy is a literal lifeline, nearly halving mortality risk, according to new research presented at the annual congress of the European Society of Cardiology.

Patients with peripheral manifestations of cardiovascular disease “are a population with an extremely high risk to suffer a heart attack or a stroke,” said Joern Dopheide, MD, during a press conference at the meeting. Despite the known benefits of statins, including the reduction of all-cause and cardiovascular death and the reduction of morbidity, adherence to guideline-directed statin therapy is far from optimal, said Dr. Dopheide of Bern (Switzerland) University Hospital.

Patients with peripheral artery disease (PAD) not taking statins had a mortality rate of 34%, more than three times that of patients adherent to an intensified statin regimen. More surprisingly, patients who had been on a statin and then stopped the medication also had a mortality rate of 33%, indistinguishable from those who had never been treated with a statin.

Although statin adherence is low in general, it’s especially low in patients with PAD, said Dr. Dopheide. Still, he said, “few systematic data exist on the prognostic value of statin adherence and the correlation between adherence and cardiovascular outcome in PAD patients.”

Accordingly, Dr. Dopheide and his coinvestigators sought to determine the association between statin adherence and survival in PAD patients. The researchers obtained baseline and follow-up data for a cohort of 691 symptomatic PAD patients seen at a single site, looking at statin dosage, LDL cholesterol levels, and survival.

The patients were followed for a period of 50 months. Dr. Dopheide said that “Over the time course, we were able to increase the statin adherence from about 73% to about 81%, and parallel to that, we were able to reduce the LDL cholesterol levels from about 97 to 83 mg/dL, and we were able to increase the intensity of patients on statin therapy.”

Dr. Dopheide said that he and his colleagues saw a dose-response effect, so that the biggest drop in cholesterol was seen in patients on high statin doses, on more potent statins, or both.

PARIS – Patients with stable coronary artery disease and type 2 diabetes saw fewer ischemic cardiovascular events when they received dual antiplatelet therapy with ticagrelor plus aspirin, though they also had more major bleeding events than patients receiving placebo plus aspirin.

The subset of patients who had received prior percutaneous coronary intervention (PCI) stood to benefit more from extended dual antiplatelet therapy (DAPT), according to clinical trial results presented to an overflow crowd at the annual congress of the European Society of Cardiology.

Findings from the full study, named The Effect of Ticagrelor on Health Outcomes in Diabetes Mellitus Patients Intervention Study (THEMIS), and from the PCI subgroup analysis were published concurrently with the presentation (N Engl J Med. 2019 Sep 1: DOI: 10.1056/NEJMoa1908077; Lancet. 2019 Sep 1: DOI:https://doi.org/10.1016/S0140-6736(19)31887-2).

“This strategy of long-term dual antiplatelet therapy may be beneficial in selected patients at low risk of bleeding, but at high risk of ischemic events,” said the study’s co-principal investigator Deepak Bhatt, MD, professor of medicine at Harvard Medical School, Boston, and executive director of interventional cardiology programs at Boston’s Brigham and Women’s Hospital. In a video interview, he hypothesized that “prior PCI may serve as a sort of ‘stress test’ for bleeding,” thus identifying a subset of patients who might benefit from long-term DAPT.

Ischemic events, the primary efficacy outcome of THEMIS, occurred in 7.7% of patients taking the P2Y12 receptor antagonist ticagrelor and 8.5% of those receiving placebo, for a hazard ratio of 0.90 favoring ticagrelor (P = .04). Ischemic events included cardiovascular deaths, myocardial infarctions (MIs), and stroke.

Looking at secondary endpoints, Dr. Bhatt said that there was no difference in cardiovascular deaths between study arms, but that ischemic strokes, all MIs, and ST segment elevation MIs were all less common for patients taking ticagrelor. All-cause mortality was similar between study groups.

Though ischemic events dropped, “This benefit was achieved at the expense of more bleeding,” said Dr. Bhatt. Major bleeding, the primary safety outcome, was seen in 2.2% of those taking ticagrelor and 1.0% of the placebo group, for a hazard ratio of 2.32 (P less than .001). Dr. Bhatt and his collaborators used the Thrombolysis in Myocardial Infarction (TIMI) criteria for major bleeding for ascertainment of this outcome.

Intracranial hemorrhage was also more common for patients on ticagrelor, though incidence was low and the absolute difference was small between groups. This complication occurred in 0.7% of ticagrelor patients and 0.5% of placebo patients, yielding a hazard ratio of 1.71 (P = .0005). “This excess wasn’t in spontaneous or procedural intracranial bleeding, but rather in traumatic intracranial hemorrhage,” said Dr. Bhatt.

Fatal bleeds affected just 0.2% of those on ticagrelor and 0.1% of those receiving placebo; this difference wasn’t statistically significant.
