In a unanimous 14-0 vote at the October meeting, ACIP members agreed that current data support the use of either the Tdap or Td pertussis vaccine in three areas: as a decennial booster, for tetanus prophylaxis and in the setting of wound management, and for additional catch-up doses based on the immunization schedule for persons aged 7 years and older.

Safety data showed no differences in safety concerns between Tdap and Td, including data from pregnant women, said Fiona Havers, MD, of the CDC’s National Center for Immunization and Respiratory Diseases (NCIRD), Atlanta.

Several of the ACIP members noted that the revised language to include both Tdap and Td reflects the increased use of Tdap and allows for maximum flexibility in clinical settings.

The revised language advises that booster doses of “either Td or Tdap” every 10 years throughout life are recommended for continued protection against tetanus and diphtheria. In addition, either Td or Tdap should be used if a tetanus toxoid–containing vaccine is indicated for prophylaxis in nonpregnant individuals.

For catch-up recommendations, which also apply to pregnant women, the committee approved the following wording for a series of three doses for individuals aged 7-18 years and 19 years and older who have never been vaccinated, that “the preferred schedule is a dose of Tdap (preferably the first dose), followed by either Tdap or Td at least 4 weeks afterward and another dose of either Td or Tdap 6-12 months later.” Individuals in these same age groups who are not fully vaccinated should receive one dose of Tdap, and a dose of either Td or Tdap if additional doses are needed.

The committee also voted unanimously 14-0 to accept the updated wording for pertussis vaccination in the Vaccines for Children program.

The ACIP members had no financial conflicts to disclose.

A 17-year-old boy was born with rough skin on his face, arms, legs, thighs, and posterior shoulders. Over the years, his face, especially the posterior lateral aspects, has become progressively redder, while the roughness has increased. The redness is amplified with heat, exertion, anger, or embarrassment. Regarding the latter, mere mention of the condition by his siblings results in worsening of the erythema. Additionally, the skin in his eyebrows is now turning red and scaly.

The patient denies a history of dandruff. His parents, who have accompanied him to the clinic, report a family history of similar skin changes on triceps and thighs, but not on faces. There is no family history of cardiac anomalies or other congenital abnormalities. The boy’s health is otherwise excellent.

EXAMINATION
The patient’s bilateral triceps are covered with fine, rough, follicular papules, which create a faintly erythematous look. Similar lesions are visible on his posterior shoulders and anterior thighs. The skin beneath his eyebrows is faintly erythematous and scaly.

The posterior sides of his face are bright red and covered with the same type of papules. The erythema grows redder as it approaches the immediate preauricular areas, where it ends abruptly, creating a sharp demarcation with the white skin closer to the ears. The visual effect is almost clownish, as if bright red makeup had been applied.

What’s the diagnosis?

DISCUSSION
This young man has all the signs of an extremely rare variant of keratosis pilaris (KP) called ulerythema ophryogenes (UO). In the United States, about 40% of adults have ordinary KP, which usually manifests in childhood (with about 80% of cases occurring in adolescent girls). KP is inherited through autosomal dominance, with highly variable penetrance, though no specific gene has been identified. In this form, KP is considered by most experts to be a minor diagnostic criterion for atopic dermatitis.

However, UO is not merely a variant of KP. Over the decades, it has been connected with more serious conditions, such as cardiofaciocutaneous syndrome, Rubinstein-Taybi syndrome, and Cornelia de Lange disease. Although these conditions are not common, they should be considered when UO is seen.

For this patient, the main concern was his appearance, especially the pronounced erythema around the periphery of his face. This aspect of the problem was addressed with a referral to a provider who can, using an assortment of lasers, try to even out his skin color and hopefully erase the sharp border at the periphery of the affected area.

For the physical discomfort caused by UO, the patient was instructed either to use general moisturizers to reduce dryness or to consider using moisturizers containing salicylic acid, which should help to reduce the prominence of the papules. For the erythema in his brows, he is using 2.5% hydrocortisone ointment two to three times a week.

TAKE-HOME LEARNING POINTS

• Ulerythema ophryogenes is a rarely encountered variant of keratosis pilaris—a condition inherited by autosomal dominance with highly variable penetrance.
• Its main significance, beyond cosmetic concerns, is the possible connection with syndromes that involve heart and structural defects (eg, cardiofaciocutaneous syndrome).
• Treatment options include heavy emollients to soften the scaly papules and laser therapy to reduce the extreme redness seen on the periphery of the face.

Strategies aimed at reducing drug-related harm should be informed by evidence, and recognize the contribution of social and economic factors to drug use, report the authors of a series of four papers published in The Lancet.

Louisa Degenhardt, PhD, and coauthors wrote in the first paper that, although the availability and use of drugs have been transformed over recent decades – including the emergence of hundreds of new psychoactive substances – professional and public policy has not yet adapted to those new realities (Lancet. 2019 Oct 23. doi: 10.1016/S0140-6736(19)32229-9).

“In many instances we have, in many countries, and in many debates, the things that are implemented are not evidence-based, and the discussion around illicit drugs is often in an incredibly emotive and morally laden one, in a way that you don’t see in other areas of public health,” Dr. Degenhardt, of the National Drug and Alcohol Research Centre at the University of New South Wales in Sydney, said in an interview. “There has been an increasing level of awareness of issues but also level of recognition that we need to have hard evidence to work out the best ways to respond.”

The paper by Dr. Degenhardt and coauthors addressed the issue of opioid use and dependence around the world, citing evidence that in 2017, 40.5 million people were dependent on opioids and 109,500 deaths were attributable to opioid overdose. An effective treatment exists in the form of opioid agonists methadone and buprenorphine, both of which are recognized as World Health Organization essential medicines.

While the best evidence for positive outcomes from opioid agonist treatment is in people using illicit opioids such as heroin, there is also evidence for their effectiveness in people with pharmaceutical opioid dependence. A study in Kentucky suggested that scaling up the use and retention of opioid agonist treatment, including in prison, could prevent 57% of overdose deaths among injecting drug users.

“Despite strong evidence for the effectiveness of a range of interventions to improve the health and well-being of people who are dependent on opioids, coverage is low, even in high-income countries,” the authors wrote. They also called for international efforts to eliminate marketing strategies that have contributed to the increase in opioid prescription and harms in North America.

The second paper examined the public health implications of legalizing cannabis for medicinal and recreational use (Hall W et al. Lancet. 2019 Oct 23. doi: 10.1016/S0140-6736(19)31789-1). Cannabis has been considered an illicit drug for more than 50 years but recently has been decriminalized or legalized in many parts of the world in recognition of the lower levels of harm, compared with other illicit substances.

Cannabis is used to treat a range of medical conditions, including muscle spasticity in multiple sclerosis. It also is used to treat pain, nausea, and vomiting in palliative care, and to reduce seizures in epilepsy. However, the authors noted that the evidence for many medical applications was absent, and that weakly regulated medical cannabis programs in some U.S. states were blurring the boundaries between medicinal and nonmedicinal use.

They also wrote that the public health effects of legalization could not be assessed, because legalization had happened only in the last 5 years.

“A major determinant of the public health effect of cannabis legalization will be the effect that it has on alcohol use,” they wrote. “The substitution of cannabis for alcohol would produce substantial public health gains, but any increase in the combined use of alcohol and cannabis could increase harm.”

The authors also looked at the effect of use of stimulants such as cocaine and amphetamines. While their use is associated with higher mortality, increased incidence of HIV and hepatitis C infection, poor mental health, and increased risk of cardiovascular events, no effective pharmacotherapies are available, and psychosocial interventions such as cognitive-behavioral therapy have only a weak effect.

“Many governments rely on punitive responses, such as involuntary detention in drug centers, despite the absence of evidence for their effectiveness and their potential to increase harm,” the authors wrote. “Substantial research investment is needed to develop more effective, innovative, and impactful prevention and treatment” (Farrell M et al. Lancet. 2019 Oct 23. doi: 10.1016/S0140-6736(19)32230-5).

They focused on interventions to prevent the transmission of blood-borne and sexually transmitted infections – such as the provision of safe injecting equipment, condoms or pre-exposure prophylaxis against HIV – and improve treatment of these, and interventions to prevent and treat overdose, injury, and other harms.

The final paper in the series explored new psychoactive substances, such as synthetic cannabinoids, stimulants, hallucinogens, and dissociative and depressant substances (Peacock A et al. Lancet 2019 Oct 23. doi: 10.1016/S0140-6736(19)32231-7).

There really needs to be massive change in systems in terms of the way monitoring occurs and the speed with which new drugs are identified, Dr. Degenhardt said in the interview. She also said the risks that are identified need to be communicated more effectively.

“At the moment, the way that drug surveillance works in most countries, things come and then particular drugs may spread in use, cause massive harm, and all of our systems of detecting and responding are not fit to detect those things in a timely way and disseminate information to reduce those risks.”

The papers were supported by European Monitoring Centre on Drugs and Drug Addiction, and the Australian National Drug and Alcohol Research Centre. The authors declared support from a range of institutions and funding bodies, and several also declared unrelated grants, funding, and other support from the pharmaceutical sector.

Tuberculosis is one of the top ten causes of death worldwide and the leading cause from a single infectious agent. In the 2012-2017 period, there were more than 9,000 cases of TB each year in the United States. The Centers for Disease Control and Prevention states that untreated TB is a greater hazard to a pregnant woman and her fetus than its treatment.

In the material below, the molecular weights, rounded to the nearest whole number, are shown in parentheses after the drug name. Those less than 1,000 or so suggest that the drug will cross the placenta throughout pregnancy. In the second half of pregnancy, especially in the third trimester, nearly all drugs will cross regardless of their molecular weight.

Para-aminosalicylic acid (Paser) (153) is most frequently used in combination with other agents for the treatment of multidrug-resistant tuberculosis; multidrug-resistant TB (MDR TB) is defined as being caused by TB bacteria that is resistant to at least isoniazid and rifampin, the two most potent TB drugs. The drug has been associated with a marked increased risk of birth defects in some, but not all, studies. Because of this potential risk, the drug is best avoided in the first trimester. The drug is excreted into breast milk, but there are no reports of its use during breastfeeding.

Bedaquiline (Sirturo) (556) is used in combination therapy for patents with multidrug-resistant tuberculosis. One report describing the use of this drug during human pregnancy has been located. Treatment was started in the last 3 weeks of pregnancy and no abnormalities were noted in the child at birth and for 2 years after birth (Emerg Infect Dis. 2017. doi: 10.3201/eid2310.161398). The CDC states that the drug should be used only in a minimum four-drug treatment regimen and administered by direct observation (MMWR Recomm Rep. 2013 Oct 25;62[RR-09]:1-12). The drug probably is excreted into breast milk, but there are no reports of its use during breastfeeding.

Capreomycin (Capastat) (653-669) is a polypeptide antibiotic isolated from Streptomyces capreolus that is given intramuscularly. The human pregnancy data are limited to three reports. The toxicity of capreomycin is similar to aminoglycosides (e.g., cranial nerve VIII and renal) and it should not be used with these agents. The CDC has classified the drug as contraindicated in pregnancy. The drug probably is excreted into breast milk, but there are no reports of its use during breastfeeding.

Cycloserine (Seromycin) (102) is a broad spectrum antibiotic. The human pregnancy data are limited but have not shown embryo-fetal harm. Although the best course is to avoid the drug during gestation, it should not be withheld because of pregnancy if the maternal condition requires the antibiotic. The American Academy of Pediatrics classified cycloserine as compatible with breastfeeding.

Ethambutol (Myambutol) (205) should be used in conjunction with other antituberculosis drugs. The human pregnancy data do not suggest an embryo-fetal risk. A frequently used regimen is ethambutol + isoniazid + rifampin. The American Academy of Pediatrics classified ethambutol as compatible with breastfeeding.

Ethionamide (Trecator) (166) is indicated when Mycobacterium tuberculosis is resistant to isoniazid or rifampin, or when the patient is intolerant to other drugs. Although the animal reproductive data suggest risk, the limited human data suggest that the risk is probably low. If indicated, the drug should not be withheld because of pregnancy. Although the molecular weight suggests that the drug will be excreted into breast milk, no reports describing the amount in milk have been located.

Isoniazid (137) is compatible in pregnancy, even though the molecular weight suggests that it will cross the placenta, because the maternal benefit is much greater than the potential embryo-fetal risk. Although the human data are limited, the molecular weight also suggests that the drug will be excreted into breast milk, but it can be considered probably compatible during breastfeeding. No reports of isoniazid-induced effects in the nursing infant have been located, but the potential for interference with nucleic acid function and for hepatotoxicity may exist.

Pyrazinamide (123) is metabolized to an active metabolite. The molecular weight, low plasma protein binding (10%), and prolonged elimination half-life (9-10 hours) suggest that the drug will cross the placenta throughout pregnancy. The drug has been used in human pregnancy without causing embryo-fetal harm. Similar results, although limited, were reported when the drug was used during breastfeeding.

Rifabutin (Mycobutin) (847) has no reported human pregnancy data, but the animal data suggest low risk. The drug probably crosses the placenta throughout pregnancy. The maternal benefit appears to outweigh the unknown risk to the embryo-fetus, so therapy should not be withheld because of pregnancy. The drug probably is excreted into breast milk.

Rifampin (Rifadin) (823) appears to be compatible in pregnancy. Several reviews and reports have concluded that the drug was not a teratogen and recommended use of the drug with isoniazid and ethambutol. However, prophylactic vitamin K₁ has been recommended to prevent drug-induced hemorrhagic disease of the newborn. There are no data regarding its use during breastfeeding, but it is probably compatible.

Rifapentine (Priftin) (877) was toxic and teratogenic in two animal species at doses close to those used in humans. In a 2018 study, however, the rates of fetal loss in pregnancies of less than 20 weeks (8/54, 15%) and congenital anomalies in live births (1/37, 3%) were within the expected background rates (Ann Am Thorac Soc. 2018 May;15[4]:570-80). There are no data regarding its use during breastfeeding, but it is probably compatible.

The CDC classifies four antituberculosis and one class of drugs as contraindicated in pregnancy. In addition to capreomycin mentioned above, they are amikacin, fluoroquinolones (ciprofloxacin, gemifloxacin, levofloxacin, lomefloxacin, moxifloxacin, ofloxacin), kanamycin, and streptomycin. These ten agents are discussed in the 11th edition of my book “Drugs in Pregnancy and Lactation,” (Wolters Kluwer Health: Riverwood, Il., 2017). If they have to be used, checking this source will provide information that has to be discussed with the patient.

For patients with epidermal growth factor receptor–mutated non–small cell lung cancer (NSCLC), adding the vascular endothelial growth factor receptor 2 (VEGFR-2) inhibitor ramucirumab to standard erlotinib therapy may extend progression-free survival, based on results from the phase 3 RELAY trial.

Considering the acceptable safety profile, this dual regimen should be considered for first-line treatment of epidermal growth factor receptor (EGFR)–mutated disease, according to lead author Kazuhiko Nakagawa, MD, PhD, of the Kindai University faculty of medicine in Osaka, Japan, and colleagues.

Dual blockade of the EGFR and VEGF pathways is supported by previous studies which pointed to efficacy among EGFR-mutated subgroups, the investigators explained in Lancet Oncology, noting that ramucirumab appeared to be the best candidate for VEGF pathway inhibition. “Ramucirumab, a human monoclonal IgG1 antibody, selectively targets VEGFR-2, thereby blocking signaling mediated by VEGF-A, VEGF-C, and VEGF-D in NSCLC,” the investigators wrote. “Therefore, ramucirumab has the potential for broader antitumor activity than inhibitors of VEGF-A.”

The trial involved 449 patients with stage IV NSCLC and an EGFR exon 21 substitution or exon 19 deletion. Patients were randomized in a 1:1 ratio to receive either erlotinib (150 mg/day) plus placebo, or erlotinib plus ramucirumab (10 mg/kg every 2 weeks). The primary endpoint was progression-free survival. Secondary endpoints included safety and toxicity, overall survival, and various measures of response.

After a median follow-up of 20.7 months, the addition of ramucirumab was associated with a significantly better median progression-free survival, at 19.4 months, compared with 12.4 months among patients who received erlotinib alone, which translates to a hazard ratio of 0.59 (P less than .0001). In each cohort, 1% of patients achieved a complete response. Partial responses were also highly similar at 75% for ramucirumab versus 74% for placebo.

Turning to safety, ramucirumab was associated with more safety concerns, including a higher rate of grade 3-4 treatment-emergent adverse events (72% vs. 54%), most often hypertension. Serious adverse events were also more frequent with ramucirumab at a rate of 29%, compared with 21% among those who received erlotinib alone.

Despite these differences, the investigators concluded that the dual regimen still offers acceptable tolerability. “Safety was consistent with the established safety profiles of the individual compounds and a metastatic NSCLC population,” they wrote. “The RELAY regimen is therefore a viable new treatment option for the initial treatment of patients with metastatic EGFR-mutated NSCLC.”

The RELAY trial was funded by Eli Lilly. The investigators reported additional relationships with AstraZeneca, Bristol-Myers Squibb, Novartis, and others.

Patients with moderate to severe atopic dermatitis who received the immunoglobulin G1 anti–interleukin-33 monoclonal antibody etokimab showed significant disease improvement 29 days after receiving a single systemic administration, according to results from a recent proof-of-concept, phase IIa study.

“Most of the focus for IL-33 pathway inhibition has been on the type 2 cytokine axis because of significant supporting genetic and functional data in both human and murine systems,” Yi-Ling Chen, a DPhil student at the University of Oxford (England), and colleagues wrote in Science Translational Medicine. “Our findings might also provide a further dimension to explain how etokimab, by inhibiting IL-33, could provide such a rapid and persistent clinical benefit as described in this report.”

In their study, 12 patients with moderate to severe AD received etokimab in a single intravenous dose of 300 mg. Prior to receiving etokimab, patients received a placebo dose and then underwent saline or house dust mite intraepidermal challenge, with researchers obtaining blister samples 1 day after challenge following placebo administration and again after patients received etokimab.

At 29 days, 83% of patients reached rapid and sustained clinical benefit under Eczema Area and Severity Index (EASI ) 50 and 33% in EASI 75, including peripheral eosinophil reduction. There also was significant reduction in skin neutrophil infiltration after patients received etokimab and then house dust mite challenge, compared with after they received placebo, .

“These findings open new therapeutic possible applications of etokimab to sterile neutrophilic disease as well as other inflammatory diseases with a clear neutrophilic involvement such as neutrophilic asthma,” the researchers said. “This first-in-class experimental medicine study has shown that in vivo in human tissue IL-33 has key upstream effects which broadly influence different and relevant inflammatory cascades and thus widen the potential of this treatment to a larger than anticipated group of diseases.

“Although excellent previous studies have demonstrated in vitro and in murine models that IL-33 is involved in neutrophil migration, the translation here to human tissue immunology shows that IL-33 plays a dominant role and effects are in part likely to be mediated instead by CXCR1,” concluded Ms. Chen and colleagues. “Therefore, specific IL-33 therapeutic intervention is not targeting a redundant system and is worthy of further investigation.”

This study was funded by AnaptysBio, which was responsible for the conception and design of the study. AnaptysBio also helped in part to analyze and interpret the data from the study, and approved it for submission. Dr. Ogg reported having served on an advisory board, as a consultant, or holds equity in Eli Lilly, Novartis, Janssen, Orbit Discovery, and UCB Pharma. Ms. Marquette and Dr. Londei reported being employees of AnaptysBio.

This study was funded by AnaptysBio, which was responsible for the conception and design of the study. AnaptysBio also helped in part to analyze and interpret the data from the study, and approved it for submission. Dr. Ogg reported having served on an advisory board, as a consultant, or holds equity in Eli Lilly, Novartis, Janssen, Orbit Discovery, and UCB Pharma. Ms. Marquette and Dr. Londei reported being employees of AnaptysBio.

Patients with moderate to severe atopic dermatitis who received the immunoglobulin G1 anti–interleukin-33 monoclonal antibody etokimab showed significant disease improvement 29 days after receiving a single systemic administration, according to results from a recent proof-of-concept, phase IIa study.

“Most of the focus for IL-33 pathway inhibition has been on the type 2 cytokine axis because of significant supporting genetic and functional data in both human and murine systems,” Yi-Ling Chen, a DPhil student at the University of Oxford (England), and colleagues wrote in Science Translational Medicine. “Our findings might also provide a further dimension to explain how etokimab, by inhibiting IL-33, could provide such a rapid and persistent clinical benefit as described in this report.”

In their study, 12 patients with moderate to severe AD received etokimab in a single intravenous dose of 300 mg. Prior to receiving etokimab, patients received a placebo dose and then underwent saline or house dust mite intraepidermal challenge, with researchers obtaining blister samples 1 day after challenge following placebo administration and again after patients received etokimab.

At 29 days, 83% of patients reached rapid and sustained clinical benefit under Eczema Area and Severity Index (EASI ) 50 and 33% in EASI 75, including peripheral eosinophil reduction. There also was significant reduction in skin neutrophil infiltration after patients received etokimab and then house dust mite challenge, compared with after they received placebo, .

“These findings open new therapeutic possible applications of etokimab to sterile neutrophilic disease as well as other inflammatory diseases with a clear neutrophilic involvement such as neutrophilic asthma,” the researchers said. “This first-in-class experimental medicine study has shown that in vivo in human tissue IL-33 has key upstream effects which broadly influence different and relevant inflammatory cascades and thus widen the potential of this treatment to a larger than anticipated group of diseases.

A new point-of-care assay designed with machine learning offers improved accuracy for rapid identification of active tuberculosis (TB) infection, according to investigators.

Martynasfoto/ThinkStock

The blood-based triage test, which relies upon four host proteins and one TB antigen, is another step closer toward diagnostic accuracy standards proposed by the World Health Organization, reported lead author Rushdy Ahmad, PhD, of the Broad Institute of MIT and Harvard in Cambridge, Mass., and colleagues. When fully developed, such a test could improve interventions for the most vulnerable patients, such as those with HIV, among whom TB often goes undiagnosed.

“Rapid and accurate diagnosis of active TB with current sputum-based diagnostic tools remains challenging in high-burden, resource-limited settings,” the investigators wrote. Their report is in Science Translational Medicine.

They went on to explain the gap that currently exists between microscopy, which is operator dependent and insensitive, and newer technologies, such as nucleic acid amplification, which are more sensitive but heavily resource dependent. “Furthermore, two of the most vulnerable and highly affected groups – young children and adults with HIV infection – are unlikely to be diagnosed using sputum because of difficulty obtaining sputum and low bacillary loads in the sample.”

To look for a more practical option, the investigators drew blood from 406 patients with chronic cough. Then, using a bead-based immunoassay with machine learning, the investigators identified four blood proteins associated with active TB infection: interleukin-6 (IL-6), IL-8, IL-18, and vascular endothelial growth factor (VEGF). Blind validation of 317 samples from patients with chronic cough in Asia, Africa, and South America showed that the four biomarkers offered a sensitivity of 80% and a specificity of 65%. By adding a fifth biomarker, an antibody against TB antigen Ag85B, the investigators were able to raise accuracy figures to 86% sensitivity and 69% specificity.

Adding even more biomarkers could theoretically raise accuracy even further, according to the investigators. The WHO minimal performance thresholds are 90% sensitivity and 70% specificity, with optimal targets slightly higher, at 95% sensitivity and 80% specificity. Although these standards have not yet been met, the investigators plan on testing the existing assay in real-world scenarios while simultaneously aiming to make it better.

“A near-term goal is ... to incrementally improve the marker panel up to an anticipated 6- to 10-plex assay,” the investigators wrote. “However, given the urgency of the problem, the possibility of incremental improvements will not delay platform refinement and field testing.”

The Bill and Melinda Gates Foundation funded the study. The investigators reported additional relationships with Quanterix Corporation and FIND.

There is increasing evidence that exercise lowers the risk of developing cancer, improves survival after a cancer diagnosis, and helps ease related health outcomes. However, relatively few cancer patients meet current physical activity guidelines – often because it wasn’t recommended by their oncologist.

thinkstock

“Observed barriers to clinicians referring patients to exercise programming include lack of awareness of the potential value of exercise in cancer populations, uncertainty regarding the safety or suitability of exercise for a particular patient, lack of awareness regarding available programs to help facilitate exercise in cancer populations, need for education and skills development for making referrals, and a belief that referrals to exercise programming are not within the scope of practice for oncology clinicians,” Kathryn H. Schmitz, PhD, from Penn State University in Hershey and coauthors from the American College of Sports Medicine International Multidisciplinary Roundtable wrote in CA: A Cancer Journal for Clinicians.

Dr. Schmitz and colleagues proposed using the American College of Sports Medicine’s Exercise Is Medicine initiative to address this gap, with a focus on asking physicians to take an assess, revise, and refer approach to recommending exercise.

Noting that there is clear evidence that patients are more likely to exercise if their oncologist recommends that they do so, the authors said a clinician’s silence on the subject of exercise could be interpreted as “tacit approval to maintain inactivity.”

To assess a patient’s level of physical activity, the authors suggested asking patients how many days during the past week they had undertaken physical activity during which their heart beat faster or they breathed harder than normal for more than 30 minutes or how often they had undertaken activity to increase muscle strength.

If the patient can safely exercise without medical supervision, the authors recommend that clinicians advise patients to increase their physical activity to achieve current recommended levels. Clinicians can refer patients to community programs to help ramp up their activity.

However, for patients who may not be able to exercise safely on their own, the authors recommend referring them to an outpatient rehabiliation professional.

“Referral to appropriate and effective programs and follow-up with an assessment of progress (or lack thereof) at subsequent visits can serve as key transition points to change a patient’s behavior and affect their tolerance of or recovery from treatment,” they wrote.

The authors stressed that oncology clinicians were not expected to prescribe specific levels of exercise or to perform extensive screening and triage of patients based on their fitness.

“Oncology clinicians, however, play a vital role in telling the patient that it is important to exercise and pointing patients in the right direction to make that happen,” they wrote.

Four authors declared grant support for participating in the study. One declared private industry funding unrelated to the study. No other conflicts of interest were declared.

MADRID – Do you ask your acne patients if they use cannabis? And if they say yes, do you suggest they consider giving it up? Dermatologist Delphine Kerob, MD, believes you should.

Bruce Jancin/MDedge News

In a late-breaker session at the annual congress of the European Academy of Dermatology and Venereology, she presented highlights of a massive international, industry-sponsored survey aimed at identifying novel external and internal factors that influence acne. One of the biggest surprises in this first-of-its-kind study was the finding of an association between cannabis use and acne: 21.1% of patients with physician-diagnosed acne were users, compared with 16.6% of controls without acne.

“I think as dermatologists we should ask these kinds of questions when we manage our patients because this may influence the course of their acne,” observed Dr. Kerob, who is the international medical director for Vichy Laboratories in Paris. The survey was sponsored by the company.

This was an Internet-based survey of 2,826 acne patients and 3,853 age- and sex-matched controls without acne. It was conducted in Canada, France, Germany, Italy, Brazil, and Russia.

The survey comprehensively addressed for the first time what lead investigator Brigitte Dreno, MD, PhD, professor and head of dermatology at Nantes (France) University Hospital and EADV Scientific Programming Committee Chair, has previously called the “acne exposome.” The exposome is essentially everything in a patient’s external and internal environment – other than genetics – that influences the occurrence and severity of the disease (J Eur Acad Dermatol Venereol. 2018 May;32[5]:812-9).

The survey probed the six major categories of exposome factors as defined by Dr. Dreno and coauthors: nutrition, air pollution, lifestyle and psychological factors, medications, skin care products, and climate. Here are the highlights:
 

Lifestyle and psychological factors. While cannabis use emerged as a novel factor linked to increased likelihood of acne, tobacco use was not – a surprising finding because other investigators had previously identified it as an acne trigger.

Feeling burdened by psychological stress was reported by 51% of acne patients and 29% of controls, for an adjusted 1.79-fold increased risk of acne.

Air pollution. Acne patients were significantly more likely to report exposure to solvent vapors, crude oil, tars, frying oil vapors, and living near an airport or close to factories with chimneys. Dr. Kerob noted that these findings are consistent with other investigators’ study of 189 residents of heavily polluted Mexico City or more pristine Cuernavaca, Mexico, with less pollution. The Mexico City cohort demonstrated an increased sebum excretion rate, lower levels of the antioxidants vitamin E and squalene in their sebum, and a less cohesive stratum corneum, along with a higher prevalence of atopic skin and facial seborrheic changes (Int J Cosmet Sci. 2015 Jun;37[3]:329-38).

Nutrition. This is a hot topic that acne patients have many questions about. Myths abound, as detailed by an expert panel including Dr. Dreno in an article entitled, “Acne and Nutrition: Hypotheses, Myths and Facts” (J Eur Acad Dermatol Venereol. 2018 Oct;32[10]:1631-7).

Dr. Kerob reported that the survey showed consumption of dairy products, probiotics, chocolate, cakes and other sweets, soft drinks, fruit juice, and whey protein were each associated with a significantly increased likelihood of acne .

Fifty-seven percent of acne patients indicated they consumed high-alcohol distilled spirits, compared with 43% of controls.

“We know that on our sebaceous glands, as well as on keratinocytes, we have receptors that will be activated by the impact of some nutrients,” she commented.

Among these receptors on sebaceous glands are the insulin growth factor–1 receptor, the leptin receptor, histamine receptors, receptors for substance P, peroxisome proliferator-activated receptors alpha, beta, and gamma, and androgen receptors, she added.

Medications. For Dr. Kerob, another surprise study finding was that 11.9% of acne patients had used an anabolic steroid- or testosterone-based hormonal drug within the previous 12 months, compared with 3.2% of controls without acne.

Cosmetic factors. The use of facial scrubs, harsh cleansers, and dermarollers was significantly more common among the acne patients.

Climate. Acne patients were more likely to live in hot and/or humid locations. For example, 24.6% of the acne group lived in a hot climate, versus 17.1% of controls.

“We think that identifying and reducing the impact of the exposome is very important for an adequate and holistic acne disease management,” the researcher concluded.

However, Eric Simpson, MD, rose from the audience to comment that he finds this plethora of associations to be of little use in advising his acne patients in clinical practice. For example, does cannabis use cause acne, or are acne patients more likely to be cannabis users as a means of coping with the social stigma surrounding their skin disease?

“I’d just caution about confounding association with causation. Let’s look at trials of removing that association to see if it actually improves acne before we make strong recommendations in the clinic,” urged Dr. Simpson, professor of dermatology at Oregon Health & Science University, Portland.

“You’re perfectly right, there,” Dr. Kerob replied. “The methodology of our study can’t separate cause from effect. But as dermatologists, if we have patients with acne that’s resistant to treatment, we need to see if there are other factors that could worsen acne outcome. And we have patients asking us questions all the time about nutrition – now we have some answers that we can provide to those patients.”

The study was sponsored by Vichy Laboratories, and Dr. Kerob is an employee of the company.

Nutrition. This is a hot topic that acne patients have many questions about. Myths abound, as detailed by an expert panel including Dr. Dreno in an article entitled, “Acne and Nutrition: Hypotheses, Myths and Facts” (J Eur Acad Dermatol Venereol. 2018 Oct;32[10]:1631-7).

Dr. Kerob reported that the survey showed consumption of dairy products, probiotics, chocolate, cakes and other sweets, soft drinks, fruit juice, and whey protein were each associated with a significantly increased likelihood of acne .

Fifty-seven percent of acne patients indicated they consumed high-alcohol distilled spirits, compared with 43% of controls.

“We know that on our sebaceous glands, as well as on keratinocytes, we have receptors that will be activated by the impact of some nutrients,” she commented.

Among these receptors on sebaceous glands are the insulin growth factor–1 receptor, the leptin receptor, histamine receptors, receptors for substance P, peroxisome proliferator-activated receptors alpha, beta, and gamma, and androgen receptors, she added.

Medications. For Dr. Kerob, another surprise study finding was that 11.9% of acne patients had used an anabolic steroid- or testosterone-based hormonal drug within the previous 12 months, compared with 3.2% of controls without acne.

Cosmetic factors. The use of facial scrubs, harsh cleansers, and dermarollers was significantly more common among the acne patients.

Climate. Acne patients were more likely to live in hot and/or humid locations. For example, 24.6% of the acne group lived in a hot climate, versus 17.1% of controls.

“We think that identifying and reducing the impact of the exposome is very important for an adequate and holistic acne disease management,” the researcher concluded.

However, Eric Simpson, MD, rose from the audience to comment that he finds this plethora of associations to be of little use in advising his acne patients in clinical practice. For example, does cannabis use cause acne, or are acne patients more likely to be cannabis users as a means of coping with the social stigma surrounding their skin disease?

“I’d just caution about confounding association with causation. Let’s look at trials of removing that association to see if it actually improves acne before we make strong recommendations in the clinic,” urged Dr. Simpson, professor of dermatology at Oregon Health & Science University, Portland.

“You’re perfectly right, there,” Dr. Kerob replied. “The methodology of our study can’t separate cause from effect. But as dermatologists, if we have patients with acne that’s resistant to treatment, we need to see if there are other factors that could worsen acne outcome. And we have patients asking us questions all the time about nutrition – now we have some answers that we can provide to those patients.”

The study was sponsored by Vichy Laboratories, and Dr. Kerob is an employee of the company.

Lazertinib, an investigational third-generation oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), has good safety and antitumor activity in patients with EGFR-mutated advanced non–small cell lung cancer (NSCLC), finds a phase 1/2 trial.

Only about one in six patients experienced a grade 3 or 4 adverse event when given the drug at various doses, according to results reported in The Lancet Oncology.

Meanwhile, 54% of patients achieved a response, with a higher rate seen among those whose tumors were positive versus negative for the T790M resistance mutation. Notably, 44% of the subgroup with brain metastases had an intracranial response.

“[O]ur results show that lazertinib is well tolerated, with responses frequently observed in patients with NSCLC harbouring both activating EGFR mutations and EGFR T790M TKI resistance mutations. Intracranial responses were also frequently seen, indicating effective blood-brain barrier penetration,” wrote senior investigator Byoung Chul Cho, MD, PhD, Cancer Center, Yonsei University College of Medicine, Seoul, South Korea, and coinvestigators.

“Lazertinib has a potential therapeutic role in the treatment of NSCLC harbouring EGFR T790M mutations, either alone or in combination with other drugs,” they concluded.

The trial was conducted in Korea among adults having advanced NSCLC with an activating EGFR mutation who experienced progression after treatment with a first- or second-generation EGFR TKI. All were treated on an open-label basis with lazertinib at dose levels from 20 mg to 320 mg once daily, continuously in 21-day cycles.

Dr. Cho and coinvestigators reported results for 127 patients (38 in a dose escalation cohort and 89 in a dose expansion cohort).

Results showed that there were no dose-limiting toxicities and no dose-dependent increases in adverse events. The leading adverse events were grade 1 or 2 rash or acne (30%) and pruritus (27%). Overall, 16% of patients experienced grade 3 or grade 4 adverse events, most commonly grade 3 pneumonia (3%). Only 3% of patients had treatment-related grade 3 or 4 adverse events, while 5% had treatment-related serious adverse events. None experienced adverse events leading to death or treatment-related death.

On independent central review, 54% of patients overall had an objective response (52% had a partial response, 2% had a complete response). The response rate was 57% in patients with T790M-positive tumors compared with 37% in patients with T790M-negative tumors.

The median duration of response was 15.2 months. With a median follow-up of 11.0 months, the median progression-free survival was 9.5 months for the whole study cohort; it was longer in patients whose tumors were positive versus negative for the T790M resistance mutations (9.7 months vs 5.4 months).

Among evaluable patients with brain metastases, the intracranial response rate was 44%, and median intracranial progression-free survival was not reached.

Dr. Cho disclosed relationships with numerous pharmaceutical companies, including Yuhan Corporation, which funded the trial.
