Dermatologists are uniquely suited to help sexual-, gender-minority patients
ORLANDO – There is a these patients, Angelo Landriscina, MD, said at the ODAC Dermatology, Aesthetic, & Clinical Conference.
“Our knowledge lagging behind is really to our own detriment,” said Dr. Landriscina, chief resident of dermatology at George Washington University, Washington. “The unique comorbidities and lived experiences of queer patients can impact their dermatologic disease. In addition to that, we are in a really unique position to provide life-changing care for these patients.”
The topic of dermatologic care for SGM patients has been discussed with interest in the dermatology community, but it has not been well studied. In one of two papers recently published in Pediatric Dermatology, Markus D. Boos, MD, PhD, from the University of Washington, Seattle, and Seattle Children’s Hospital, and coauthors noted that there is a particular knowledge gap in how to care for SGM pediatric and adolescent patients (Pediatr Dermatol. 2019 Sep;36[5]:581-6; 587-93).
In his presentation, Dr. Landriscina outlined the differences between sexual orientation – an emotional, romantic, or sexual attraction to others – and gender identity, or how one perceives their own gender. Lesbian, gay, transgender, and queer/questioning are classical definitions, but SGM patients may also self-identify in any number of other ways. Some SGM patients may identify as gender-fluid or nonbinary, while genderqueer is an umbrella term for individuals who don’t identify with typical gender roles. On the topic of pronouns, asking SGM patients how they want to be referred to is ideal, but the singular they is considered a gender-neutral term that should work for most situations.
There are also terms to avoid: “Homosexual” may be acceptable to some SGM patients, but is from an era when same-sex attraction was pathologized; “sexual preference” characterizes sexuality as a choice; the term “lifestyle” perpetuates the idea that all SGM patients are the same; and referring to transgender patients as "pre-op" or "post-op" is problematic as these terms imply that transgender identity is defined by a medical transition. Using transgender or gay as a noun, or the word transsexual, is offensive and shouldn’t be used at all, according to Dr. Landriscina.
As these terms continue to change and be redefined, dermatologists are likely to encounter terms they are unfamiliar with in the clinic, but he emphasized that attendees need not know every term to care for these patients. “The easiest way to be right in all of these situations is to let your patients define themselves,” he said, but noted that “assumptions are your worst enemy. You’re going to have to ask the hard questions.”
Updating understanding of SGM patients
Much of the medical community’s understanding of SGM patients hasn’t been updated in decades, Dr. Landriscina said. For example, medical school students typically learn about SGM risk factors that only apply to men who have sex with men (MSM), but there is new interest in caring for transgender patients within dermatology. The focus on classical notions for treating MSM can be reductive, Dr. Landriscina explained. “It boils a whole community of people down to one disease process. I think that we need to expand the thought that there are other associations here. There are other risks these patients face.”
In contrast, dermatologists who strive to understand their patients can better see them as a whole person, can engage in a better differential diagnosis, are aware of the current comorbidities SGM patients face that affect dermatologic disease, and can even work with the patient toward preventative care.
“It’s been decades since we’ve had a paradigm shift about this, and I think it’s time,” he said.
Overall, SGM patients have a higher likelihood of suffering from mental illness and suicidal ideation, with 10%-20% of lesbian, gay, and bisexual patients attempting suicide. Gender-minority patients have a significantly higher rate of attempting suicide at 40%. SGM patients are also more likely to be homeless and uninsured, and have the highest rates of tobacco, alcohol, and illicit drug use. In the SGM population, there is a higher likelihood of being victimized, and discriminated against, with this risk being much higher in transgender patients.
For MSM, there is a high risk of HIV and other STIs such as herpes simplex virus type 2 (HSV2), human papillomavirus (HPV), gonorrhea, and chlamydia, Dr. Landriscina said. They are also at risk for hepatitis A, B, and C; clusters of meningococcal meningitis; and human herpes virus 8. While MSM are more likely to use sunscreen, they also are more likely to use tanning beds and not wear protective clothing outdoors, and are at a greater risk of skin cancer. The risks of body dysmorphia and eating disorders are also increased for MSM.
While there is not as much research on risk factors for women who have sex with women (WSW), they are still at risk for HIV, HSV, and HPV and are less likely to engage in safe sex practices. For women who have sex with both men and other women, there is an even greater risk of STIs. While WSW are more likely to perceive less need for screening, they should be given the same screening as all other women, and dermatologists can help by ensuring these patients are connected with primary care providers, he said.
Dermatologic sequelae for transgender patients
For patients who transition from male to female, there is little information on their sexual risk from studies, but their care should be managed similarly to MSM, Dr. Landriscina said. When seeing transgender patients, dermatologists should be aware of issues of gender dysphoria, but not offer any intervention without first having a conversation about the patient’s hopes and goals. “Not every patient will have the means or desire to have everything that you can offer,” he said.
For patients who choose to undergo a female-to-male transition, dermatological sequelae may include classical manifestations of androgen excess from hormone therapy such as acne and androgenic alopecia; acne, miliaria, tinea corporis, contact dermatitis from chest binding; and surgical scars and keloids. For acne, isotretinoin is an option if a case is severe, but dermatologists should be aware these patients may still be able to become pregnant. There is no consensus on treatment for androgenic alopecia, but use of finasteride might block wanted secondary sex characteristics, Dr. Landriscina noted.
Patients who undergo a male-to-female transition may develop melasma or asteatotic eczema while receiving estrogen therapy; unwanted facial or body hair; and complications from illicit “filler” injections that may cause foreign-body granulomas, bacterial or atypical mycobacterial infection, lymphedema, and scarring.
Transgender patients may choose to undergo aesthetic treatments that can affirm their gender and decrease their gender dysphoria, augment the effects of hormone therapy and gender-confirmation surgery, and improve their quality of life. “While this has classically fallen under the purview of plastic surgery, I feel like we’re uniquely positioned to provide really life-changing aesthetic services to these patients,” Dr. Landriscina said.
Creating an inclusive environment is key to successfully caring for SGM patients. Any practice policies should have SGM-inclusive language, employees should receive mandatory LGBTQ+ focused training, and a point person should oversee LGBTQ+ matters, according to the Joint Commission’s LGBT Guide. Practices should also begin collecting data on sexual orientation and gender identity, which may help patients who are reluctant to vocally disclose their sexual orientation and gender identity and expand understanding of SGM patients. “Before you even walk into that visit, you know what the patient’s identity is, how they want to be addressed,” said Dr. Landriscina. “It also shows patients that you value what their identities are and that you’re competent in taking care of them.”
Dr. Landriscina encouraged attendees to take the information they learned in the session and “run with it.”
“Go for it. Keep learning,” he said. “There’s more about this topic than I even had the chance to include. Your patients are going to appreciate your dedication to them.”
In an interview, Adam Friedman, MD, professor and interim chair of dermatology at George Washington University and medical director of ODAC, acknowledged the large gaps in care for SGM patients and the unique role dermatologists can play in their care, both in terms of medical and surgical procedures.
“There are specific considerations that we as dermatologists need to think about in terms of just quality of life, potentially mental disease, homelessness, access to care. I think if we consider the whole picture, we can not only provide dermatologic care, but maybe serve as a pivot point to direct them to other specialists, and other physicians, and even nonphysicians who play a role in all facets of life to really get these individuals all the care, in broader senses, that they need,” he said.
Dr. Landriscina reported no relevant conflicts of interest.

EXPERT ANALYSIS FROM ODAC 2020
Adult survivors of childhood cancer are experiencing fewer major cardiac events
Adult survivors of pediatric cancers appear to be experiencing fewer major cardiac events in adulthood partly because of reduced radiotherapy exposure, especially among survivors of Hodgkin lymphoma, recent research published in BMJ has shown.
“Contemporary cancer treatment has focused on advancing cure rates while attempting to minimize long term adverse effects,” Daniel A. Mulrooney, MD, of the Division of Cancer Survivorship, Department of Oncology, at St. Jude Children’s Research Hospital, Arlington, Va., and colleagues wrote. “Patterns of exposure to cardiotoxic treatment have changed over time, with fewer children receiving chest directed radiation, with lower doses and smaller volumes for those who do, and an increased use of anthracyclines, albeit with reduced cumulative doses as the risk for late-onset heart failure became apparent.”
Although research has been published on improved survival rates of children who underwent cancer treatment in the 1990s, compared with those who received treatment in the 1980s and 1970s, Dr. Mulrooney and colleagues set out to determine whether cardiac outcomes were reduced as well. They conducted a retrospective study of 23,462 5-year survivors of pediatric cancer, which consisted of leukemia, brain cancer, Hodgkin lymphoma, non-Hodgkin lymphoma, renal tumors, neuroblastoma, soft-tissue sarcomas, and bone sarcomas diagnosed between January 1970 and December 1999. Researchers compared the cardiac outcomes of the survivors, including heart failure, coronary artery disease, valvular heart disease, pericardial disease, and arrhythmias, with a comparison group of their siblings (n = 5,057) separated by decade. The adult survivors tended to be women (46% vs. 40%) with a median age of 6.1 years at diagnosis and 27.7 years at final follow-up.
Of the 6,193 participants treated for cancer in the 1970s, the 20-year cumulative incidence of heart failure was 0.69%, while the 9,363 participants treated in the 1980s had an incidence of 0.74%, and 7,906 participants in the 1990s had a cumulative incidence of 0.54% over 20 years. The 20-year cumulative incidence for coronary artery disease (CAD) was 0.38% for participants in the 1970s, 0.24% for participants in the 1980s, and 0.19% for participants in the 1990s (P less than .01). Researchers noted the 20-year cumulative incidence of valvular disease, pericardial disease, and arrhythmias did not decrease between the 1970s and the 1990s.
When comparing the rate of major cardiac events of participants in the 1980s and 1990s with those of the 1970s, CAD diagnoses significantly decreased in the 1980s (hazard ratio, 0.65; 95% confidence interval, 0.45-0.92) and 1990s (HR, 0.53; 95% CI, 0.36-0.77), while there was no significant decrease in heart failure or valvular heart disease risk over time. After adjusting for cardiac radiation, overall risk for CAD was attenuated (HR, 0.90; 0.78-1.05), and Hodgkin lymphoma survivors saw the greatest change between unadjusted (HR, 0.77; 95% CI, 0.66-0.89) and adjusted risk (HR, 0.87; 95% CI, 0.69-1.10) when accounting for cardiac radiation.
“While additional longitudinal follow-up is needed to establish whether similar reductions in the cumulative incidence of heart failure can be confirmed in multivariable analysis, these results suggest that efforts to modify cancer therapies in children and promote health surveillance for survivors are beginning to show benefits not only in overall survival but also in late adverse cardiac effects,” the researchers concluded.
In a related editorial, Mike Hawkins, DPhil, of the Centre for Childhood Cancer Survivor Studies, Institute of Applied Health Research at the University of Birmingham (England), and colleagues said that, while measuring cardiotoxicity is important for this patient population, traditional risk factors with independent associations to cardiac outcomes should also be studied. Guidelines on follow-up for these patients are also needed to inform clinical practice, such as those produced by the International Late Effects of Childhood Cancer Guideline Harmonization Group, they added.
“Survivorship issues are extremely important to patients, their families, and their doctors,” they said. “In two research priority setting initiatives in the United Kingdom, detailed consultation with patients with cancer, survivors, families, friends, and healthcare professionals identified further research into the consequences of cancer as a top priority.”
This study was funded by grants from the National Cancer Institute, Cancer Center Support (CORE) to St. Jude Children’s Research Hospital and American Lebanese Syrian Associated Charities. The authors of the study and the editorial reported no relevant conflicts of interest.

In a related editorial, Mike Hawkins, DPhil, of the Centre for Childhood Cancer Survivor Studies, Institute of Applied Health Research at the University of Birmingham (England), and colleagues said that, while measuring cardiotoxicity is important for this patient population, traditional risk factors with independent associations to cardiac outcomes should also be studied. Guidelines on follow-up for these patients are also needed to inform clinical practice, such as those produced by the International Late Effects of Childhood Cancer Guideline Harmonization Group, they added.
“Survivorship issues are extremely important to patients, their families, and their doctors,” they said. “In two research priority setting initiatives in the United Kingdom, detailed consultation with patients with cancer, survivors, families, friends, and healthcare professionals identified further research into the consequences of cancer as a top priority.”

Adult survivors of pediatric cancers appear to be experiencing fewer major cardiac events in adulthood partly because of reduced radiotherapy exposure, especially among survivors of Hodgkin lymphoma, recent research published in BMJ has shown.
“Contemporary cancer treatment has focused on advancing cure rates while attempting to minimize long term adverse effects,” Daniel A. Mulrooney, MD, of the Division of Cancer Survivorship, Department of Oncology, at St. Jude Children’s Research Hospital, Arlington, Va., and colleagues wrote. “Patterns of exposure to cardiotoxic treatment have changed over time, with fewer children receiving chest directed radiation, with lower doses and smaller volumes for those who do, and an increased use of anthracyclines, albeit with reduced cumulative doses as the risk for late-onset heart failure became apparent.”
Although research has been published on improved survival rates of children who underwent cancer treatment in the 1990s, compared with those who received treatment in the 1980s and 1970s, Dr. Mulrooney and colleagues set out to determine whether cardiac outcomes were reduced as well. They conducted a retrospective study of 23,462 5-year survivors of pediatric cancer, which consisted of leukemia, brain cancer, Hodgkin lymphoma, non-Hodgkin lymphoma, renal tumors, neuroblastoma, soft-tissue sarcomas, and bone sarcomas diagnosed between January 1970 and December 1999. Researchers compared the cardiac outcomes of the survivors, including heart failure, coronary artery disease, valvular heart disease, pericardial disease, and arrhythmias, with a comparison group of their siblings (n = 5,057) separated by decade. The adult survivors tended to be women (46% vs. 40%) with a median age of 6.1 years at diagnosis and 27.7 years at final follow-up.
Of the 6,193 participants treated for cancer in the 1970s, the 20-year cumulative incidence of heart failure was 0.69%, while the 9,363 participants treated in the 1980s had an incidence of 0.74%, and 7,906 participants in the 1990s had a cumulative incidence of 0.54% over 20 years. The 20-year cumulative incidence for coronary artery disease (CAD) was 0.38% for participants in the 1970s, 0.24% for participants in the 1980s, and 0.19% for participants in the 1990s (P less than .01). Researchers noted the 20-year cumulative incidence of valvular disease, pericardial disease, and arrhythmias did not decrease between the 1970s and the 1990s.
When comparing the rate of major cardiac events of participants in the 1980s and 1990s with those of the 1970s, CAD diagnoses significantly decreased in the 1980s (hazard ratio, 0.65; 95% confidence interval, 0.45-0.92) and 1990s (HR, 0.53; 95% CI, 0.36-0.77), while there was no significant decrease in heart failure or valvular heart disease risk over time. After adjusting for cardiac radiation, overall risk for CAD was attenuated (HR, 0.90; 0.78-1.05), and Hodgkin lymphoma survivors saw the greatest change between unadjusted (HR, 0.77; 95% CI, 0.66-0.89) and adjusted risk (HR, 0.87; 95% CI, 0.69-1.10) when accounting for cardiac radiation.

Adolescent alcohol, opioid misuse linked to risky behaviors
Binge drinking and misuse of opioids led to risky behavior during adolescence, two studies from the journal Pediatrics highlighted. And the binge drinking in high school may predict risky driving behaviors up to 4 years after high school.
Federico E. Vaca, MD, of the developmental neurocognitive driving simulation research center at Yale University, New Haven, Conn., and colleagues examined the associations between risky driving behaviors and binge drinking of 2,785 adolescents in the nationally representative, longitudinal NEXT Generation Health Study. The researchers studied the effects of binge drinking on driving while impaired (DWI), riding with an impaired driver (RWI), blackouts, extreme binge drinking, and risky driving.
The adolescents were studied across seven waves, with Wave 1 beginning in the 2009-2010 school year (10th grade; mean age, 16 years), and data extended up to 4 years after high school. Of all adolescents enrolled, 91% completed Wave 1, 88% completed Wave 2, 86% completed Wave 3 (12th grade), 78% completed Wave 4, 79% completed Wave 5, 84% completed Wave 6, and 83% completed Wave 7 (4 years after leaving high school) of the study.
High school binge drinking predicts later risky behavior
About one-quarter of adolescents reported binge drinking in Waves 1-3, with an incidence of 27% in Wave 1, 24% in Wave 2, and 27% in Wave 3. Adolescents who reported binge drinking in Wave 3 had a higher likelihood of DWI in subsequent waves, with nearly six times higher odds in Wave 5 and more than twice as likely in Wave 7, researchers said. Binge drinking in Wave 3 also was associated with greater than four times higher odds of RWI in Wave 4, and more than two and a half times higher odds of RWI in Wave 7. Among adolescents who reported binge drinking across 3 years in high school, there was a higher likelihood of extreme binge drinking in Wave 7, and higher likelihood of risky driving after graduating.
Impact of parental knowledge of drinking
in some waves. Father monitoring knowledge of drinking in Waves 1-3 lowered the odds of DWI by 30% in Wave 5 and 20% in Wave 6, while also lowering the odds of RWI in Wave 4 and Wave 7 by 20%.
Mother knowledge of drinking in Waves 1-3 was associated with 60% lower odds of DWI in Wave 4, but did not lower odds in any wave for RWI.
Overall, parental support for not drinking lowered odds for DWI by 40% in Waves 4 and 5, and by 30% in Wave 7 while also lowering odds of RWI in Wave 4 by 20%.
The results are consistent with other studies examining risky driving behavior and binge drinking in adolescent populations, but researchers noted that “to an important but limited extent, parental practices while the teenager is in high school may protect against DWI, RWI, and blackouts as adolescents move into early adulthood.”
“Our findings are relevant to prevention programs that seek to incorporate alcohol screening with intentional inquiry about binge drinking. Moreover, our results may be instructive to programs that seek to leverage facets of parental practices to reduce health-risk contexts for youth,” Dr. Vaca and colleagues concluded. “Such prevention activities coupled with strengthening of policies and practices reducing adolescents’ access to alcohol could reduce later major alcohol-related health-risk behaviors and their consequences.”
Opioid misuse and risky behavior
In a second study, Devika Bhatia, MD, of the University of Colorado at Denver, Aurora, and colleagues examined opioid misuse in a nationally-representative sample of 14,765 adolescents from the Centers for Disease Control and Prevention’s 2017 Youth Risk Behavior Surveillance Survey. The researchers measured opioid misuse by categorizing adolescents into groups based on whether they had ever misused prescription opioids and whether they had engaged in risky driving behavior, violent behavior, risky sexual behavior, had a history of substance abuse, or attempted suicide.
Dr. Bhatia and colleagues found 14% of adolescents in the study reported misusing opioids, with an overrepresentation of 17-year-old and 18-year-old participants reporting opioid misuse (P less than .0001). there were no statistically significant difference between those who misused opioids and those who did not in terms of race, ethnicity, or sex.
Those adolescents who reported misusing opioids were 2.8 times more likely to not use a seatbelt; were 2.8 times more likely to have RWI; were 5.8 times more likely to have DWI; or 2.3 times more likely to have texted or emailed while driving. In each of these cases, P was less than .0001.
Adolescents who misused opioids also had significantly increased odds of engaging in risky sexual behaviors such as having sex before 13 years (3.9 times); having sex with four or more partners (4.8 times); using substances before sex (3.6 times); and not using a condom before sex (2.0 times). In each of these cases, P was less than .0001.
Additionally, adolescents in this category were between 5.4 times and 22.3 times more likely to use other substances (P less than .0001 for 10 variables); 4.9 times more likely to have attempted suicide (P less than .0001); or more likely to have engaged in violent behavior such as getting into physical fights (4.0 times), carrying a weapon (3.4 times) or a gun (5.1 times) within the last 30 days. In the four latter cases, P was less than .0001.
“With the ongoing opioid epidemic, pediatricians and child psychiatrists are likely to be more attuned to opioid misuse in their patients,” Dr. Bhatia and colleagues concluded. “If youth are screening positive for opioid misuse, pediatricians, nurses, social workers, child psychiatrists, and other providers assessing adolescents may have a new, broad range of other risky behaviors for which to screen regardless of the direction of the association.”
Substance use screening for treating substance use disorder traditionally has been is provided by a specialist, Jessica A. Kulak, PhD, MPH, said in an interview. “However, integration of care services may help to change societal norms around problematic substance use – both by decreasing stigma associated with substance use, as well as increasing clinicians’ preparedness, knowledge, and confidence in preventing and intervening on adolescents’ substance experimentation and use.” She recommended that clinicians in primary care improve their training by using the Substance Abuse and Mental Health Services Administration’s Screening, Brief Intervention, and Referral to Treatment program, which is available as a free online course.
Confidentiality is important in adolescent health, said Dr. Kulak, who is an assistant professor in the department of health, nutrition, and dietetics at State University of New York at Buffalo. “When discussing sensitive topics, such as binge drinking and opioid misuse, adolescents may fear that these or other risky activities may be disclosed to parents or law enforcement officials. Therefore, adolescent health providers should be aware of local, state, and federal laws pertaining to the confidentiality of minors.”
She added, “adolescents are often susceptible to others’ influences, so having open communication and support from a trusted adult – be it a parent or clinician – may also be protective against risky behaviors.”
The study by Vaca et al. was funded by the National Institutes of Health with support from the Intramural Research Program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development; the National Heart, Lung, and Blood Institute; the National Institute on Alcohol Abuse and Alcoholism; the National Institute on Drug Abuse; and the Maternal and Child Health Bureau of the Health Resources and Services Administration. The study by Bhatia et al. had no external funding. The authors from both studies reported no relevant financial disclosures. Dr. Kulak said she had no financial disclosures or other conflicts of interest.

These newly published reports indicate the high prevalence of risky behaviors and their associations – cross-sectionally and longitudinally – with major threats to adolescent health – so asking about alcohol use, opioid misuse, and associated health risks is truly “in the lane” of clinicians, school professionals, and parents who see and care about adolescents.
At this point, I think it’s incontrovertible that clinicians should screen adolescents to learn about their physical, emotional, and behavioral health. And they should seek opportunities for professional training, skills development, and expansion of their professional networks so they are able to address – individually or collaboratively via referrals – the behavioral and psychosocial health risks of their patients.
The good news is that there is growing awareness of the importance of using validated screening tools to identify patient behavioral health risks – including those pertaining to adolescent and young adult alcohol use and opioid misuse. “Best practice” dictates that screening approaches rely on asking questions using structured tools; intuition and “just winging it” are not effective or reliable for identifying patient behavior. Forward-looking clinics and practices could be asking patients to report about health behaviors in the waiting room (on a computer tablet, for example), or even remotely (using a secure app or data collection tool) in advance of a visit. Asking should be periodic – since behaviors can change fairly rapidly among young people. The benefit is that patient-reported information can be processed in advance to cue clinician follow-up and intervention. And youth tend to share more about their behaviors when they are asked electronically, rather than face to face. Intelligent screens can provide near real-time estimation of risk – to support in-office brief intervention tailored to the risk level of a young person or to trigger follow-up.
These studies indicate that binge alcohol use and misuse of prescription opioids among adolescents are real, pervasive, and deserving of our considered attention. There is no magic bullet. However busy clinicians may have a significant role to play in identifying and addressing these problems.

“With the ongoing opioid epidemic, pediatricians and child psychiatrists are likely to be more attuned to opioid misuse in their patients,” Dr. Bhatia and colleagues concluded. “If youth are screening positive for opioid misuse, pediatricians, nurses, social workers, child psychiatrists, and other providers assessing adolescents may have a new, broad range of other risky behaviors for which to screen regardless of the direction of the association.”
Substance use screening for treating substance use disorder traditionally has been is provided by a specialist, Jessica A. Kulak, PhD, MPH, said in an interview. “However, integration of care services may help to change societal norms around problematic substance use – both by decreasing stigma associated with substance use, as well as increasing clinicians’ preparedness, knowledge, and confidence in preventing and intervening on adolescents’ substance experimentation and use.” She recommended that clinicians in primary care improve their training by using the Substance Abuse and Mental Health Services Administration’s Screening, Brief Intervention, and Referral to Treatment program, which is available as a free online course.
Confidentiality is important in adolescent health, said Dr. Kulak, who is an assistant professor in the department of health, nutrition, and dietetics at State University of New York at Buffalo. “When discussing sensitive topics, such as binge drinking and opioid misuse, adolescents may fear that these or other risky activities may be disclosed to parents or law enforcement officials. Therefore, adolescent health providers should be aware of local, state, and federal laws pertaining to the confidentiality of minors.”
She added, “adolescents are often susceptible to others’ influences, so having open communication and support from a trusted adult – be it a parent or clinician – may also be protective against risky behaviors.”
The study by Vaca et al. was funded by the National Institutes of Health with support from the Intramural Research Program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development; the National Heart, Lung, and Blood Institute; the National Institute on Alcohol Abuse and Alcoholism; the National Institute on Drug Abuse; and the Maternal and Child Health Bureau of the Health Resources and Services Administration. The study by Bhatia et al. had no external funding. The authors from both studies reported no relevant financial disclosures. Dr. Kulak said she had no financial disclosures or other conflicts of interest.

Dual e-cigarette and combustible tobacco use compound respiratory disease risk
according to recent longitudinal analysis published in the American Journal of Preventive Medicine.
E-cigarettes have been promoted as a safer alternative to combustible tobacco, and until recently, there has been little and conflicting evidence by which to test this hypothesis. This study conducted by Dharma N. Bhatta, PhD, and Stanton A. Glantz, PhD, of the Center for Tobacco Control Research and Education at the University of California, San Francisco, is one of the first longitudinal examinations of e-cigarette use and controlling for combustible tobacco use.
Dr. Bhatta and Dr. Glantz performed a multivariable, logistic regression analysis of adults enrolled in the nationally representative, population-based, longitudinal Population Assessment of Tobacco and Health study. The researchers analyzed the tobacco use of adults in the study in three waves, following them through wave 1 (September 2013 to December 2014), wave 2 (October 2014 to October 2015), and wave 3 (October 2015 to October 2016), analyzing the data between 2018 and 2019. Overall, wave 1 began with 32,320 participants, and 15.1% of adults reported respiratory disease at baseline.
Lung or respiratory disease was assessed by asking participants whether they had been told by a health professional that they had chronic obstructive pulmonary disease, chronic bronchitis, emphysema, or asthma. The researchers defined e-cigarette and combustible tobacco use as participants who never, currently, or formerly used e-cigarettes or smoked combustible tobacco. Participants who indicated they used e-cigarettes or combustible tobacco frequently or infrequently were placed in the current-user group, while past users were those participants who said they used to, but no longer use e-cigarettes or combustible tobacco.
The results showed former e-cigarette use (adjusted odds ratio, 1.34; 95% confidence interval, 1.23-1.46) and current e-cigarette use (aOR, 1.32; 95% CI, 1.17-1.49) were associated with an increased risk of having incident respiratory disease.
The data showed a not unexpected statistically significant association between former combustible tobacco use (aOR, 1.29; 95% CI, 1.14-1.47) as well as current combustible tobacco use (aOR, 1.61; 95% CI, 1.42-1.82) and incident respiratory disease risk.
There was a statistically significant association between respiratory disease and former or current e-cigarette use for adults who did not have respiratory disease at baseline, after adjusting for factors such as current combustible tobacco use, clinical variables, and demographic differences. Participants in wave 1 who reported former (aOR, 1.31; 95% CI, 1.07-1.60) or current e-cigarette use (aOR, 1.29; 95% CI, 1.03-1.61) had a significantly higher risk of developing incident respiratory disease in subsequent waves. There was also a statistically significant association between use of combustible tobacco and subsequent respiratory disease in later waves of the study (aOR, 2.56; 95% CI, 1.92-3.41), which the researchers noted was independent of the usual risks associated with combustible tobacco.
The investigators also looked at the link between dual use of e-cigarettes and combustible tobacco and respiratory disease risk. “The much more common pattern is dual use, in which an e-cigarette user continues to smoke combusted tobacco products at the same time (93.7% of e-cigarette users at wave 2 and 91.2% at wave 3 also used combustible tobacco; 73.3% of e-cigarette users at wave 2 and 64.9% at wave 3 also smoked cigarettes),” they wrote.
The odds of developing respiratory disease for participants who used both e-cigarettes and combustible tobacco were 3.30, compared with a participant who never used e-cigarettes, with similar results seen when comparing e-cigarettes and cigarettes.
“Although switching from combustible tobacco, including cigarettes, to e-cigarettes theoretically could reduce the risk of developing respiratory disease, current evidence indicates a high prevalence of dual use, which is associated with in-creased risk beyond combustible tobacco use,” the investigators wrote.
Harold J. Farber, MD, FCCP, professor of pediatrics in the pulmonary section at Baylor College of Medicine and Texas Children’s Hospital, both in Houston, said in an interview that the increased respiratory risk among dual users, who are likely using e-cigarettes and combustible tobacco together as a way to quit smoking, is particularly concerning.
“There is substantial reason to be concerned about efficacy of electronic cigarette products. Real-world observational studies have shown that, on average, tobacco smokers who use electronic cigarettes are less likely to stop smoking than those who do not use electronic cigarettes,” he said. “People who have stopped tobacco smoking but use electronic cigarettes are more likely to relapse to tobacco smoking than those who do not use electronic cigarettes.”
Dr. Farber noted that there are other Food and Drug Administration–approved medications for treating tobacco addiction. In addition, the World Health Organization, American Medical Association, Centers for Disease Control and Prevention, and FDA have all advised that e-cigarettes should not be used as smoking cessation aids, he said, especially in light of current outbreak of life-threatening e-cigarette and vaping lung injuries currently being investigated by the CDC and FDA.
“These study results suggest that the CDC reports of e-cigarette, or vaping, product use–associated lung injury are likely to be just the tip of the iceberg,” he said. “Although the CDC has identified vitamin E acetate–containing products as an important culprit, it is unlikely to be the only one. There are many substances in the emissions of e-cigarettes that have known irritant and/or toxic effects on the airways.”
Dr. Bhatta and Dr. Glantz acknowledged several limitations in their analysis, including the possibility of recall bias, not distinguishing between nondaily and daily e-cigarette or combustible tobacco use, and combining respiratory conditions together to achieve adequate power. The study shows an association, but the mechanism by which e-cigarettes may contribute to the development of lung disease remains under investigation.
This study was supported by grants from the National Institute on Drug Abuse; the National Cancer Institute; the FDA Center for Tobacco Products; the National Heart, Lung, and Blood Institute; and the University of California, San Francisco Helen Diller Family Comprehensive Cancer Center Global Cancer Program. Dr. Bhatta and Dr. Glantz reported no relevant conflicts of interest.

Well-tolerated topical capsaicin formulation reduces knee OA pain
ATLANTA – Use of high-concentration topical capsaicin was associated with reduced pain, a longer duration of clinical response, and was well tolerated in patients with knee osteoarthritis, compared with lower concentrations of capsaicin and placebo, according to recent research presented at the annual meeting of the American College of Rheumatology.
While the ACR has recommended topical capsaicin for the relief of hand and knee OA pain, there are issues with using low-dose capsaicin, including the need for multiple applications and burning, stinging sensations at applications sites. As repeat exposure to capsaicin results in depletion of pain neurotransmitters and a reduction in nerve fibers in a dose-dependent fashion, higher doses of topical capsaicin are a potential topical treatment for OA pain relief, but their tolerability is low, Tim Warneke, vice president of clinical operations at Vizuri Health Sciences in Columbia, Md., said in his presentation.
“[P]oor tolerability has limited the ability to maximize the analgesic effect of capsaicin,” Mr. Warneke said. “While [over-the-counter] preparations of capsaicin provide some pain relief, poor tolerability with higher doses has really left us wondering if we haven’t maximized capsaicin’s ability to provide pain relief.”
Mr. Warneke and colleagues conducted a phase 2, multicenter, double-blind, parallel-group, vehicle-controlled trial where 120 patients with knee OA were randomized in a 1:1:1 ratio to receive 5% capsaicin topical liquid (CGS-200-5), 1% capsaicin topical liquid (CGS-200-1), or vehicle (CGS-200-0) and then followed up to 90 days. “The CGS-200 vehicle was developed to mitigate the burning, stinging pain of capsaicin,” Mr. Warneke said. “It allows the 5% concentration to be well tolerated, which opens the door for increased efficacy, including durability of response.”
Inclusion criteria were radiographically confirmed knee OA using 1986 ACR classification criteria, a Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score of 250 mm or greater, and more than 3 months of chronic knee pain. While patients were excluded for use of topical, oral, or injectable corticosteroids in the month prior to enrollment, they were allowed to continue using analgesics such as NSAIDs if they maintained their daily dose throughout the trial. Mr. Warneke noted the study population was typical of an OA population with a mostly female, mostly Caucasian cohort who had a median age of 60 years and a body mass index of 30 kg/m2. Patients had moderate to severe OA and were refractory to previous pain treatments.
The interventions consisted of a single 60-minute application of capsaicin or vehicle to both knees once per day for 4 consecutive days, and patients performed the applications in the clinic. The investigators compared change in WOMAC pain scores between the groups at 31 days, 60 days, and 90 days post dose.
The results at 31 days showed a 46.2% reduction in WOMAC pain scores from baseline for patients using CGS-200-5, compared with a 28.3% reduction in the vehicle group (P = .02). At 60 days, there was a 49.1% reduction in WOMAC pain scores in the CGS-200-5 group, compared with 21.5% in patients using vehicle (P = .0001), and a 42.8% reduction for patients in the CGS-200-5 group at 90 days, compared with 22.8% in the vehicle group (P = .01). The CGS-200-1 group did not reach the primary efficacy WOMAC pain endpoint, compared with vehicle.
A post hoc analysis showed that there was a significantly greater mean reduction in WOMAC total score for patients using CGS-200-5, compared with vehicle at 31 days (P = .02), 60 days (P = .0005), and 90 days post dose (P = .005). “This durability of clinical response for single applications seems to be a promising feature of CGS-200-5,” Mr. Warneke said.
Concerning safety and tolerability, there were no serious adverse events, and one patient discontinued treatment in the CGS-200-5 group. When assessing tolerability at predose, 15-minute, 30-minute, 60-minute, and 90-minute postdose time intervals, the investigators found patients experienced mild or moderate adverse events such as erythema, edema, scaling, and pruritus, with symptoms decreasing by the fourth consecutive day of application.
Mr. Warneke acknowledged the “robust placebo response” in the trial and noted it is not unusual to see in pain studies. “It’s something that is a challenge for all of us who are in this space to overcome, but we still have significant differences here and they are statistically significant as well,” he said. “You have to be pretty good these days to beat the wonder drug placebo, it appears.”
Four authors in addition to Mr. Warneke reported being employees of Vizuri Health Sciences, the company developing CGS-200-5. One author reported being a former consultant for Vizuri. Three authors reported they were current or former employees of CT Clinical Trial & Consulting, a contract research organization employed by Vizuri to execute and manage the study, perform data analysis, and create reports.

Mr. Warneke and colleagues conducted a phase 2, multicenter, double-blind, parallel-group, vehicle-controlled trial where 120 patients with knee OA were randomized in a 1:1:1 ratio to receive 5% capsaicin topical liquid (CGS-200-5), 1% capsaicin topical liquid (CGS-200-1), or vehicle (CGS-200-0) and then followed up to 90 days. “The CGS-200 vehicle was developed to mitigate the burning, stinging pain of capsaicin,” Mr. Warneke said. “It allows the 5% concentration to be well tolerated, which opens the door for increased efficacy, including durability of response.”
Inclusion criteria were radiographically confirmed knee OA using 1986 ACR classification criteria, a Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score of 250 mm or greater, and more than 3 months of chronic knee pain. While patients were excluded for use of topical, oral, or injectable corticosteroids in the month prior to enrollment, they were allowed to continue using analgesics such as NSAIDs if they maintained their daily dose throughout the trial. Mr. Warneke noted the study population was typical of an OA population with a mostly female, mostly Caucasian cohort who had a median age of 60 years and a body mass index of 30 kg/m2. Patients had moderate to severe OA and were refractory to previous pain treatments.
The interventions consisted of a single 60-minute application of capsaicin or vehicle to both knees once per day for 4 consecutive days, and patients performed the applications in the clinic. The investigators compared change in WOMAC pain scores between the groups at 31 days, 60 days, and 90 days post dose.
The results at 31 days showed a 46.2% reduction in WOMAC pain scores from baseline for patients using CGS-200-5, compared with a 28.3% reduction in the vehicle group (P = .02). At 60 days, there was a 49.1% reduction in WOMAC pain scores in the CGS-200-5 group, compared with 21.5% in patients using vehicle (P = .0001), and a 42.8% reduction for patients in the CGS-200-5 group at 90 days, compared with 22.8% in the vehicle group (P = .01). The CGS-200-1 group did not reach the primary efficacy WOMAC pain endpoint, compared with vehicle.
A post hoc analysis showed that there was a significantly greater mean reduction in WOMAC total score for patients using CGS-200-5, compared with vehicle at 31 days (P = .02), 60 days (P = .0005), and 90 days post dose (P = .005). “This durability of clinical response for single applications seems to be a promising feature of CGS-200-5,” Mr. Warneke said.
Concerning safety and tolerability, there were no serious adverse events, and one patient discontinued treatment in the CGS-200-5 group. When assessing tolerability at predose, 15-minute, 30-minute, 60-minute, and 90-minute postdose time intervals, the investigators found patients experienced mild or moderate adverse events such as erythema, edema, scaling, and pruritus, with symptoms decreasing by the fourth consecutive day of application.
Mr. Warneke acknowledged the “robust placebo response” in the trial and noted it is not unusual to see in pain studies. “It’s something that is a challenge for all of us who are in this space to overcome, but we still have significant differences here and they are statistically significant as well,” he said. “You have to be pretty good these days to beat the wonder drug placebo, it appears.”
Four authors in addition to Mr. Warneke reported being employees of Vizuri Health Sciences, the company developing CGS-200-5. One author reported being a former consultant for Vizuri. Three authors reported they were current or former employees of CT Clinical Trial & Consulting, a contract research organization employed by Vizuri to execute and manage the study, perform data analysis, and create reports.

REPORTING FROM ACR 2019
ACR and EULAR release first classification criteria for IgG4-related disease
The American College of Rheumatology and the European League Against Rheumatism have released the first classification criteria for IgG4-related disease.
Although it was first recognized as a distinct disease in 2003, investigators have since learned that IgG4-related disease (IgG4-RD) is not particularly rare. Specialists across many different fields of medicine now treat IgG4-RD, which affects multiple organ systems, and the pancreas, kidneys, and orbits are most commonly affected by severe disease.
“IgG4-RD has proven to be a remarkable window into human immunology, and the insights investigators have made from studying this disease have already led to important discoveries in other rheumatic diseases, such as scleroderma,” John H. Stone, MD, professor of medicine at Harvard Medical School and director of clinical rheumatology at Massachusetts General Hospital, both in Boston, said in an interview.
To develop the classification criteria, 86 experts from five continents across various subspecialties including rheumatology, internal medicine, ophthalmology, pathology, gastroenterology, allergology, pulmonology, radiology, neurology, nephrology, and others met as a working group in 2016, achieving consensus on 79 criteria. They then narrowed down the number of items to 8 domains and 29 items within a set of inclusion and exclusion criteria for the draft classification criteria. For the final classification criteria, the working group applied weighting to each inclusion criteria item within a domain on a Likert scale (–5 to 5 range), removing items that were not significantly attributable to IgG4-RD classification (those with –2 to 2 scores).
The final IgG4-RD criteria are divided into three classification steps: entry criteria, exclusion criteria, and inclusion criteria. Patients who meet the entry criteria should have clinical or radiologic involvement of one or more organs consistent with IgG4-RD, such as the pancreas, salivary glands, bile ducts, orbits, kidney, lung, aorta, retroperitoneum, pachymeninges, or thyroid gland. Patients could alternatively meet the entry criteria by having “pathologic evidence of an inflammatory process accompanied by a lymphoplasmacytic infiltrate of uncertain etiology in one of these same organs,” the authors wrote.
If a patient meets the entry criteria, their case is examined against 32 clinical, serologic, radiologic, and pathologic items and specific disease inclusions. Any exclusion criteria present in a case means the patient does not meet the criteria for IgG4-RD classification.
The third step is to evaluate whether a patient meets inclusion criteria consisting of clinical findings, serologic results, radiology assessments, and pathology interpretations across eight domains: immunostaining, head and neck gland involvement, chest, pancreas and biliary tree, kidney, and the retroperitoneum. Each criterion has a weight, and if a patient has a score of 20 or higher, they meet the classification criteria for IgG4-RD.
“The final criteria set is easy to use and lends itself well to adaptation in an electronic format, which we have already instituted at my hospital,” said Dr. Stone, who is also director of the international panel of experts who created the criteria.
Two cohorts were used to validate the IgG4-RD classification criteria. In the first cohort, investigators used 771 patients (85% of the total cohort) in whom they were “confident” or “very confident” of a diagnosis of IgG4-RD or a mimicker to assess the test performance with a classification threshold of 20 points. The researchers found the criteria had a specificity of 99.2% (95% confidence interval, 97.2%-99.8%) and a sensitivity of 85.5% (95% CI, 81.9%-88.5%). The experts used a second validation cohort of 402 additional patients (83% of the total cohort) with suspected IgG4-RD or a mimicker using the same confident and very confident metric. The panel assembled this cohort because of minor definition changes in inclusion and exclusion criteria that had been made after the derivation set of patients had been collected, but the definitions of inclusion and exclusion criteria used in the two validation cohorts were exactly the same. Overall, the specificity of the criteria was 97.8% (95% CI, 93.7%-99.2%) and the sensitivity was 82.0% (95% CI, 77.0%-86.1%) for IgG4-RD classification in this second group.
Dr. Stone said that more investigations, including multicenter clinical trials, are being organized for patients with IgG4-RD, and these classification criteria will help to identify which patients to include in these studies.
“These rigorous ACR/EULAR classification criteria will help guide us through some of the most important challenges of studying this disease well,” Dr. Stone said. “I’m anticipating major advances in this field in the years to come, triggered in part by the strength of having sound classification criteria.”
The authors reported no relevant conflicts of interest.

VEDOSS study describes predictors of progression to systemic sclerosis
ATLANTA – , according to recent results from the Very Early Diagnosis Of Systemic Sclerosis (VEDOSS) study presented at the annual meeting of the American College of Rheumatology.
“Our data show that thanks [to a] combination of the signs that characterize the various phases of the disease, patients can be diagnosed [with systemic sclerosis] in the very early stages,” first author Silvia Bellando-Randone, MD, PhD, assistant professor in the division of rheumatology at the University of Florence (Italy), said in her presentation.
Dr. Bellando-Randone and colleagues performed a longitudinal, observational study of 742 patients (mean 45.7 years old) at 42 centers in a cohort of mostly women (90%), nearly all of whom had had Raynaud’s phenomenon for longer than 36 months (97.5%). Patients were excluded if they had systemic sclerosis based on ACR 1980 classification criteria and/or ACR–European League Against Rheumatism 2013 criteria, had systemic sclerosis together with other connective-tissue diseases, or were unlikely to be present for three consecutive annual exams. Data collection began in March 2012 with follow-up of 5 years.
The researchers determined the positive predictive values (PPV) and negative predictive values (NPV) of clinical features, systemic sclerosis–specific antibodies, and nailfold video capillaroscopy (NVC) abnormalities on progression from Raynaud’s phenomenon to systemic sclerosis. Laboratory data collected at baseline included presence of antinuclear antibodies (ANA), anticentromere antibodies (ACA), anti-DNA topoisomerase I antibodies (anti-Scl-70), anti-U1RNP antibodies, anti-RNA polymerase III antibodies (ARA), N-terminal pro b-type natriuretic peptides (NT-proBNP), and C-reactive protein/erythrocyte sedimentation rate. Dr. Bellando-Randone and colleagues also collected clinical, pulmonary function, lung high-resolution CT, echocardiographic, and ECG data at baseline.
Predictions were based on these factors alone and in combination. Overall, 65% of patients had positive ANA. Other baseline characteristics present in patients that predicted systemic sclerosis included positive ACA/anti-Scl-70/ARA (32%), NVC abnormalities such as giant capillaries (25%), and puffy fingers (17%).
Using Kaplan-Meier analysis, the researchers found 7.4% of 401 patients who were ANA positive progressed to meet ACR-EULAR 2013 criteria, and the percentage of these patients increased to 29.3% at 3 years and 44.1% at 5 years. When the researchers considered disease-specific antibodies alone, 10.6% of 90 patients progressed from Raynaud’s phenomenon to systemic sclerosis within 1 year, 39.6% within 3 years, and 50.3% within 5 years. When the researchers analyzed disease-specific antibodies and NVC abnormalities together, 16% of 72 patients progressed to systemic sclerosis within 1 year, 61.7% within 3 years, and 77.4% within 5 years.
Puffy fingers also were a predictor of progression, and 14.4% of 69 patients with puffy fingers alone progressed from Raynaud’s phenomenon to systemic sclerosis at 1 year, 47.7% at 3 years, and 67.9% at 5 years. Considering puffy fingers and disease-specific antibodies together, 20% of 27 patients progressed at 1 year, 56.3% at 3 years, and 91.3% at 5 years. No patients with puffy fingers together and NVC abnormalities progressed to systemic sclerosis at 1 year, but 60.4% of 22 patients progressed at 3 years before plateauing at 5 years. For patients with NVC abnormalities alone, 7.1% progressed to systemic sclerosis from Raynaud’s phenomenon at 1 year, 39.4% at 3 years, and 52.7% at 5 years.
“Regarding capillaroscopy, we have to say that not all centers that participated were equally screened in capillaroscopy, and so we cannot assume the accuracy of this data,” she said.
Dr. Bellando-Randone noted that, apart from puffy fingers, disease-specific antibodies, and NVC abnormalities, patients were more likely to have a history of esophageal symptoms if they progressed to systemic sclerosis (37.3%), compared with patients who did not progress (23.6%; P = .003).
Puffy fingers alone were an independent predictor of systemic sclerosis (PPV, 78.9%; NPV, 45.1%) as well as in combination with disease-specific antibodies (PPV, 94.1%; NPV, 43.9%). The combination of disease-specific antibodies plus NVC abnormalities also independently predicted progression to systemic sclerosis (PPV, 82.2%; NPV, 50.4%). In a Cox multivariate analysis, disease-specific antibodies (relative risk, 5.4; 95% confidence interval, 3.7-7.9) and puffy fingers (RR, 3.0; 95% CI, 2.0-4.4) together were strongly predictive of progression from Raynaud’s phenomenon to systemic sclerosis (RR, 4.3; 95% CI, 2.6-7.3).
“This is really important for the risk stratification of patients [in] the very early stages of the disease, even if these data should be corroborated by larger data in larger studies in the future,” said Dr. Bellando-Randone.
The investigators reported having no conflicts of interest.

For patients with NVC abnormalities alone, 7.1% progressed to systemic sclerosis from Raynaud’s phenomenon at 1 year, 39.4% at 3 years, and 52.7% at 5 years.
“Regarding capillaroscopy, we have to say that not all centers that participated were equally screened in capillaroscopy, and so we cannot assume the accuracy of this data,” she said.
Dr. Bellando-Randone noted that, apart from puffy fingers, disease-specific antibodies, and NVC abnormalities, patients were more likely to have a history of esophageal symptoms if they progressed to systemic sclerosis (37.3%), compared with patients who did not progress (23.6%; P = .003).
Puffy fingers alone were an independent predictor of systemic sclerosis (PPV, 78.9%; NPV, 45.1%) as well as in combination with disease-specific antibodies (PPV, 94.1%; NPV, 43.9%). The combination of disease-specific antibodies plus NVC abnormalities also independently predicted progression to systemic sclerosis (PPV, 82.2%; NPV, 50.4%). In a Cox multivariate analysis, disease-specific antibodies (relative risk, 5.4; 95% confidence interval, 3.7-7.9) and puffy fingers (RR, 3.0; 95% CI, 2.0-4.4) together were strongly predictive of progression from Raynaud’s phenomenon to systemic sclerosis (RR, 4.3; 95% CI, 2.6-7.3).
“This is really important for the risk stratification of patients [in] the very early stages of the disease, even if these data should be corroborated by larger data in larger studies in the future,” said Dr. Bellando-Randone.
The investigators reported having no conflicts of interest.

Tofacitinib improves disease activity in patients with polyarticular-course JIA
ATLANTA – Treatment of polyarticular-course juvenile idiopathic arthritis with tofacitinib led to significantly fewer disease flares and greater improvement in disease activity than with placebo in a phase 3, multinational, randomized, double-blind, controlled withdrawal study presented at the annual meeting of the American College of Rheumatology.
Hermine I. Brunner, MD, director of the division of rheumatology at Cincinnati Children’s Hospital Medical Center, and colleagues conducted the study in 225 patients between 2 and less than 18 years old with polyarticular-course juvenile idiopathic arthritis (pJIA; n = 184), psoriatic arthritis (PsA; n = 20), or enthesitis-related arthritis (ERA; n = 21). Patients were included if they had an inadequate response or intolerance to a disease-modifying antirheumatic drug and active disease with five or more active joints in the case of pJIA and three or more active joints in PsA or ERA.
Dr. Brunner presented results only for pJIA patients; the results for PsA and ERA patients will be assessed and presented separately.
The researchers divided their study into two sections. In the open-label portion of the study, patients received twice-daily tofacitinib (Xeljanz) at a dose of 5 mg or a weight-based lower dose in patients under 40 kg for 18 weeks. A total of 173 patients met JIA ACR30 response criteria, defined as 30% or greater improvement in three of six JIA core set variables and worsening in no more than one of the core set variables, and then were randomized in part 2 of the study to continue the same dose of tofacitinib or receive placebo until 44 weeks. Dr. Brunner noted that most patients who discontinued treatment in parts 1 and 2 did so because of insufficient clinical response rather than from adverse events.
Disease flare occurrence between 18 and 44 weeks was measured as a primary endpoint, and key secondary endpoints included JIA ACR30/50/70 response and change in Childhood Health Assessment Questionnaire Disability Index (CHAQ-DI) scores from part 2 baseline. The researchers used a “gatekeeping approach” that sequenced outcome measures in their statistical analysis to control for false positives in primary and secondary outcomes, where statistical significance could be achieved only if the previous outcome in the sequence was statistically significant.
Patients had a median age of 13 years, and most were female, white (about 87%), and between one-third and one-half of patients were based in North America. JIA disease duration was a median of about 2.5 years, C-reactive protein was about 0.3 mg/dL, and median CHAQ-DI scores were about 0.9 across tofacitinib and placebo groups. Other baseline characteristics were balanced between the two groups, Dr. Brunner said.
“Patients with polyarticular-course JIA in the open-label study experienced a rapid improvement of their disease activity from very high to moderate within 18 weeks,” Dr. Brunner said in her presentation. “[T]ofacitinib demonstrated significantly greater efficacy versus placebo in patients with polyarticular-course JIA based on occurrence of fewer flares in part 2.”
Specifically, disease flare occurred in 29.2% of patients by 44 weeks in the tofacitinib group, compared with 52.9% of patients in the placebo group (P = .0031), for an overall 54% lower risk of flare among patients receiving tofacitinib (hazard ratio, 0.459; 95% confidence interval, 0.268-0.785; P = .0037). The response rate was higher for patients receiving tofacitinib at 44 weeks when measured by JIA ACR30 (70.8% vs. 47.1% with placebo; P = .0031) or by JIA ACR50 (66.7% vs. 47.1%; P = .0166) and JIA ACR70 criteria (54.2% vs. 37.1%; P = .0387). The change in CHAQ-DI score also improved at 44 weeks to a significantly greater extent in the tofacitinib group than with placebo (–0.09 vs. 0.03; P = .0292).
“The safety profile of tofacitinib in children with JIA was comparable to what you have seen or known in the [rheumatoid arthritis] population, and no new safety risks were identified in this pediatric population,” Dr. Brunner said.
The researchers reported ties with Pfizer, which funded the study, and more than two dozen other pharmaceutical companies.

Repeat LTBI testing best in patients taking biologics with new risk factors
ATLANTA – Patients taking biologics who received latent tuberculosis testing on an annual basis were unlikely to convert from a negative QuantiFERON test to a positive result, which suggests that the test may be unnecessary for patients without new tuberculosis risk factors, according to research presented at the annual meeting of the American College of Rheumatology.
In addition, nearly all of the cost of repeat testing for latent tuberculosis infection (LTBI) went to patients who were not diagnosed with or treated for LTBI, noted Urmi Khanna, MD, a dermatologist with the Cleveland Clinic.
“All in all, about $1.4 million U.S. dollars was spent just on additional QuantiFERON testing, and only 1% of this additional cost was actually spent on testing patients who were diagnosed with and treated for latent tuberculosis,” Dr. Khanna said in her presentation at the meeting.
“Based on this study, we would like to propose that, in low incidence TB regions such as the United States, repeat LTBI testing in patients on biologic therapies should be focused on patients who have new risk factors for TB infection since their last screening,” she said.
The National Psoriasis Foundation has recommended patients be screened annually for LTBI, and the Centers for Disease Control and Prevention and the ACR have recommended patients taking biologics be screened annually for LTBI if they have new risk factors for TB, such as coming into contact with immigrants, a person infected with TB, immunosuppressed individuals, or persons working in areas where TB might be present. Annual screening was also recently added to the Medicare Merit-Based Incentive Payment System (MIPS), which will affect physician reimbursement. “Based on [the addition of this quality outcome measure], we expect that more and more physicians will adopt this practice of annual LTBI screening in all patients on biologics,” Dr. Khanna said.
She and her colleagues examined QuantiFERON tuberculosis test (QFT) results of 10,914 patients from the Cleveland Clinic Foundation between August 2007 and March 2019 where patients were receiving systemic biologic therapy for inflammatory or autoimmune conditions, including nearly 32% with inflammatory bowel disease, 29% with rheumatoid arthritis, and 25% with psoriatic disease. Overall, 5,212 patients were included in the final analysis, and patients had a median of three QFT results. Patients had a median age of 41 years, had taken an average of 1.80 biologics during follow-up, and had a median biologic therapy duration of about 49 months. The most common biologics used were adalimumab (33%), etanercept (17%), and infliximab (17%).
Of these patients, 4,561 patients had negative QFTs (88%), 172 patients had one or more positive QFTs (3%), and 479 patients had one or more indeterminate QFTs (9%). For patients who converted from a negative QFT to a positive QFT, the most common risk factors were exposure to someone with TB (26%), immigrating or traveling to an endemic area (26%), and occupational exposure (16%).
Within the group with one or more positive QFTs, there were 108 patients with baseline positive QFTs prior to starting biologic therapy (2.1%), 61 patients who converted from a baseline negative QFT to a positive QFT (1.2%), and 3 patients where a positive result overlapped with a negative result (0.1%). The majority of patients who converted to a positive QFT result had borderline positive results (70.5%), defined as 0.35 to 1 IU/mL, compared with 29.5% of converters who had a positive QFT result of more than 1.0 IU/mL.
Among the 61 patients who converted to a positive QFT result, 28 patients with LTBI (46%) and 1 patient with an active case of TB (2%) were diagnosed and treated. The active TB case was a 29-year-old patient with inflammatory bowel disease and ankylosing spondylitis receiving adalimumab who had recently traveled to India.
The researchers also examined the cost of additional QFTs in each group. Among negative QFTs, the cost of an additional 9,611 tests was $1,201,375. The cost of additional tests for indeterminate QFTs was $136,200, but Dr. Khanna noted that 99.99% of additional tests in this group were for patients never diagnosed with or treated for LTBI. Additional tests for positive QFTs cost another $47,700, and 26.1% of patients in this group were diagnosed and received treatment for LTBI, compared with 73.9% who did not receive an LTBI diagnosis or treatment.
In the discussion session following the presentation, Dr. Khanna emphasized that discontinuing annual screening in low-risk patients was not standard of care at the Cleveland Clinic, and this study was conducted to raise awareness of focusing testing on patients with new TB risk factors.
Dr. Khanna reported no relevant financial disclosures. A few of her coauthors reported financial relationships with pharmaceutical companies.

Lp(a) molar concentration flags CVD, diabetes risk
Lipoprotein(a) molar concentration, rather than apolipoprotein(a) size, appears to be the factor that drives lipoprotein(a)-based cardiovascular disease, according to research published in the Journal of the American College of Cardiology.
The causal association between lipoprotein(a), or Lp(a), and cardiovascular disease has been previously established, but exactly what attribute of Lp(a) is related to cardiovascular risk is not known, Daniel F. Gudbjartsson, PhD, of deCODE genetics and the University of Iceland in Reykjavik, and colleagues wrote in their study. The researchers set out to determine whether Lp(a) molar concentration or apolipoprotein(a), or apo(a), size affects cardiovascular risk. In addition, Dr. Gudbjartsson and colleagues examined the relationship between Lp(a) and type 2 diabetes. While low levels of Lp(a) have been linked to type 2 diabetes, the researchers sought to examine whether low Lp(a) molar concentration levels were also associated with type 2 diabetes risk.
“With Lp(a)-lowering drugs being developed, it is important to understand which attributes of Lp(a) best capture the cardiovascular risk and the consequences of Lp(a) lowering,” noted Dr. Gudbjartsson and colleagues.
Using Mendelian randomization, the researchers assessed Lp(a) molar concentration and kringle IV type 2 (KIV-2) repeat sequence variants to determine a causal relationship between both variants and disease risk. Lp(a) molar concentration serum samples were measured using particle-enhanced turbidimetric immunoassay, while KIV-2 repeats were genotyped with real-time polymerase chain reaction.
Overall, 143,087 participants from Iceland had their genetic information analyzed; of these, 17,715 participants had coronary artery disease, and 8,734 had type 2 diabetes. Lp(a) molecular concentration was analyzed in 12,137 participants and genetically imputed into 130,950 Icelanders, and KIV-2 repeats were estimated in 22,771 Icelanders and genetically imputed into 120,316 Icelanders.
Dr. Gudbjartsson and colleagues found there was a dose-dependent association between Lp(a) molar concentration and risk of coronary artery disease (CAD), peripheral artery disease, aortic valve stenosis, heart failure, and lifespan. In participants in whom Lp(a) molar concentration was at the 79th percentile (50 units of molarity [nM]), the odds ratio was 1.11, and for those in the 99th percentile (250 nM), there was an odds ratio of 2.01 when compared with participants with a median Lp(a) molar concentration of 14 nM. “Lp(a) molar concentration fully explained the Lp(a) association with CAD, and there was no residual association with apo(a) size,” the researchers said.
Participants who were not at increased risk for CAD included those with few KIV-2 repeats and participants with the splice variant G4925A. “This suggested that risk prediction based on Lp(a) should only depend on molar concentration and that treatment of Lp(a) should focus on lowering the molar concentration in subjects with high Lp(a) levels, regardless of the apo(a) size distribution,” Dr. Gudbjartsson and colleagues wrote.
Among participants with type 2 diabetes examined, the 10% of participants with Lp(a) molar concentrations of less than 3.5 nM were at the highest risk of developing type 2 diabetes.
In an accompanying editorial, Benoit J. Arsenault, PhD, of the Quebec Heart and Lung Institute, said that the findings of an association between Lp(a) concentration and atherosclerotic cardiovascular diseases (ASCVD) from Gudbjartsson et al. are important, particularly if they can be replicated in more diverse populations (doi: 10.1016/j.jacc.2019.06.083). “Investigating the association between Lp(a) levels, apo(a) isoform size, and ASCVD risk in different populations is important because the distribution of Lp(a) levels appears to be different across ethnic groups,” he said.
Despite the link between absolute Lp(a) concentrations and cardiovascular disease, cardiovascular outcome trials will need be conducted, Dr. Arsenault noted.
“In the post-statin and post-genomic era, finding much needed therapeutic targets for residual cardiovascular risk can be compared to a gold-digging expedition. Like a map to the location of the gold, GWAS [genome-wide association studies] and Mendelian randomization studies are consistently pointing us in the direction of Lp(a),” he said. “It is time to coordinate our efforts to dig where the map told us, to see once and for all if we will find the golden target of residual cardiovascular risk that we are hoping for and to give hope to high-risk patients with elevated Lp(a) levels.”

Lipoprotein(a) molar concentration, rather than apolipoprotein(a) size, appears to be the factor that drives lipoprotein(a)-based cardiovascular disease, according to research published in the Journal of the American College of Cardiology.
The causal association between lipoprotein(a), or Lp(a), and cardiovascular disease has been previously established, but exactly what attribute of Lp(a) is related to cardiovascular risk is not known, Daniel F. Gudbjartsson, PhD, of deCODE genetics and the University of Iceland in Reykjavik, and colleagues wrote in their study. The researchers set out to determine whether Lp(a) molar concentration or apolipoprotein(a), or apo(a), size affects cardiovascular risk. In addition, Dr. Gudbjartsson and colleagues examined the relationship between Lp(a) and type 2 diabetes. While low levels of Lp(a) have been linked to type 2 diabetes, the researchers sought to examine whether low Lp(a) molar concentration levels were also associated with type 2 diabetes risk.
“With Lp(a)-lowering drugs being developed, it is important to understand which attributes of Lp(a) best capture the cardiovascular risk and the consequences of Lp(a) lowering,” noted Dr. Gudbjartsson and colleagues.
Using Mendelian randomization, the researchers assessed Lp(a) molar concentration and kringle IV type 2 (KIV-2) repeat sequence variants to determine a causal relationship between both variants and disease risk. Lp(a) molar concentration serum samples were measured using particle-enhanced turbidimetric immunoassay, while KIV-2 repeats were genotyped with real-time polymerase chain reaction.
Overall, 143,087 participants from Iceland had their genetic information analyzed; of these, 17,715 participants had coronary artery disease, and 8,734 had type 2 diabetes. Lp(a) molecular concentration was analyzed in 12,137 participants and genetically imputed into 130,950 Icelanders, and KIV-2 repeats were estimated in 22,771 Icelanders and genetically imputed into 120,316 Icelanders.
