Data support the further study of HDAC9 inhibition as a treatment for secondary stroke prevention.

The antiepileptic drug (AED) sodium valproate may reduce the risk of recurrent ischemic stroke, according to data published in the January issue of Stroke. The treatment deserves further evaluation, according to investigators. A randomized controlled trial could confirm its effect on the risk of recurrent stroke, they said.

The Wellcome Trust Case Control Consortium 2 genome-wide association study found an association between a mutation in HDAC9 and an increased risk of ischemic stroke resulting from large artery disease. Valproate is a nonspecific inhibitor of HDAC9 activity and attenuates atherosclerosis in mice deficient in apolipoprotein E. Two large studies found an association between valproate and a decreased risk of incident stroke.

An Analysis of Three Large Cohort Studies

Hugh S. Markus, DM, lead author of the article and a neurologist in the Stroke Research Group at the University of Cambridge in the United Kingdom, and colleagues hypothesized that inhibiting HDAC9 activity could prevent large artery atherosclerotic ischemic stroke. To test this hypothesis, they examined data from three large cohort studies—the South London Stroke Register, the Vitamins to Prevent Stroke Study, and the Oxford Vascular Study. These prospective studies enrolled patients with stroke or transient ischemic attack and had long follow-up periods.

Dr. Markus and colleagues chose recurrent stroke as their primary end point. They examined prescription data for AEDs, as well as other variables such as study, age, sex, and diagnosis of epilepsy. The researchers examined the data using survival analysis and Cox regression.

Valproate Halved Risk of Recurrent Stroke

In all, 11,949 patients were included in the pooled analysis. A total of 168 participants received valproate, and 530 received other AEDs. Recurrent stroke occurred in 17 patients receiving valproate, 1,470 of 11,781 participants who never were prescribed valproate, 105 patients receiving other AEDs, and 1,426 of 11,312 patients not prescribed AEDs.

Throughout follow-up, stroke-free survival was greater among participants receiving valproate than among other participants. At year 15, stroke-free survival was 86% among patients receiving valproate, compared with 74% among patients without valproate exposure.

For nonselective control populations, the difference in survival between valproate exposure and nonexposure was not significant, but the difference between valproate exposure and exposure to other AEDs was significant. For selective control populations, the difference in survival between valproate exposure and no AED exposure was not significant, nor was the difference between valproate exposure and other AED exposure.

Cox hazard models adjusted for all covariates indicated that valproate was associated with a reduced risk of stroke, compared with all patients without valproate exposure (hazard ratio [HR], 0.50). In addition, valproate exposure was associated with reduced risk of stroke, compared with the group prescribed other AEDs (HR, 0.41).

“Although the design of our study is prone to systematic and random error and cannot infer causality, the results provide some evidence for the prestudy hypothesis and suggest that sodium valproate ... may be associated with a reduced stroke recurrence rate,” said Dr. Markus and colleagues. “Sodium valproate is a nonspecific HDAC inhibitor (inhibiting a wide range of HDACs) and has other actions independent of HDAC9 inhibition. Hence, a more specific inhibitor of HDAC9 might have a stronger effect in reducing the risk of recurrent stroke.”

Is anxiety normal or pathological? Age of onset is key

Article Type

Fri, 01/18/2019 - 17:23

 

NEW YORK – Anxiety has become a common descriptor for fears, worries, or concerns, but the diagnosis of anxiety as a pathological affective disorder in children requires attention to the age of onset and the types of triggers, according to a presentation at a pediatric psychopharmacology update held by the American Academy of Child and Adolescent Psychiatry.

“Normal anxiety involves predictable triggers like a test in school,” explained John T. Walkup, MD, director of the division of child and adolescent psychiatry at Children’s Hospital, Northwestern University, Chicago. In the absence of the trigger, the symptoms abate or resolve.

In contrast, the symptoms of pathological anxiety are provoked by normal developmental experiences like going to bed or ordering food in a restaurant. These symptoms may abate in the absence of triggers, but it is the excessive and debilitating reactions to normative experiences that help identify pathology.

“Age of onset is an important clue,” said Dr. Walkup, reporting that signs of pathological anxiety typically develop between the ages of 6 and 12 years. In comparison, symptoms of ADHD and autism spectrum disorder typically begin at younger ages, while the onset of affective disorders, such as depression or bipolar disease, typically occur at older ages.

Persistent symptoms may not be limited to children with pathological anxiety. Dr. Walkup said many children contend with “bad schools, troubled homes, and interpersonal violence,” creating “a huge population that meets the criteria for anxiety disorder,” even when the solution is eliminating the triggers rather than seeking an underlying psychiatric disorder.

Conversely, families of children with clear manifestations of anxiety might resist this diagnostic label.

“Parents tell me that their kids are not anxious; they are stressed out,” Dr. Walkup recounted. “These families see the external world as the problem for a kid who actually has internal problems regulating their anxious state.”

Rather than quibbling about terminology, patients should be educated about the very real threat posed by persistent and untreated symptoms, Dr. Walkup suggested. Pathological anxiety, regardless of the term used, is not a phase.

“Some of these kids do recover from childhood onset anxiety, but more often, the condition tracks to adolescence or adulthood,” Dr. Walkup said. The consequences can be serious because of accumulating disability produced by maladaptive behaviors, such as avoidance or social isolation. He contended that many adults with personality disorders are experiencing the consequences of distorted thinking and problematic emotional responses that began with childhood anxiety.

Currently, duloxetine is the only pharmacologic therapy approved for the treatment of anxiety disorder in children. But evidence-based strategies, including other types of selective serotonin reuptake inhibitors as well as cognitive-behavioral therapy, increasingly have been well defined. Strategies should be individualized and combined, Dr. Walkup argued.

“Children with anxiety need to learn to cope. If you medicate them to control the anxiety, it does not necessarily mean that they will learn how to live anxiety free,” Dr. Walkup said, reiterating that pathological anxiety often persists indefinitely even after effective therapy diminishes the symptom burden. To improve a supportive family environment for an anxious child, he encouraged educating parents about the condition.

“One of the many books published on childhood anxiety may be all they need,” said Dr. Walkup, listing several examples, such as “You and Your Anxious Child” (New York: Avery, 2013) coauthored by Anne Marie Albano, PhD, a professor of child psychiatry at Columbia University in New York.

As anxiety is such a ubiquitous human experience, many parents trivialize the pathological variety, Dr. Walkup said. Educating patients about the immediate and long-term risks of pathological anxiety is important. The associated symptoms are not a phase, as some parents are likely to contend. He believes that early diagnosis and effective management can change the trajectory of a lifelong threat.

Dr. Walkup reported no potential conflicts of interest.

Can a Model Predict Pediatric SUDEP Risk?

Article Type
Changed
Mon, 01/07/2019 - 10:38
Researchers used conditional logistic regression to evaluate nine variables.

WASHINGTON, DC—In a pediatric epilepsy population, number of antiepileptic drugs (AEDs) used and prior epilepsy surgery may predict sudden unexpected death in epilepsy (SUDEP), according to a study presented at the 71st Annual Meeting of the American Epilepsy Society.

Kishore Vedala, a medical student at the Medical College of Georgia at Augusta University, and colleagues sought to develop a predictive model for at-risk pediatric patients by conducting a matched case–control study.

Using records from the Medical College of Georgia, the researchers identified 11 SUDEP cases that occurred between 2007 and 2017. They compared the cases with 53 controls matched for age, epilepsy duration, and gender. The researchers used a conditional logistic regression model to evaluate the following nine potential predictor variables: mental retardation, seizure frequency, seizure type, prior status epilepticus, number of AEDs, prior epilepsy surgery, vagus nerve stimulator therapy, seizure progression, and awake interictal heart rate variability. They identified the optimum predictor models using Akaike’s information criterion and evaluated model performance using receiver operating characteristic area under the curve (AUC).

Prior status epilepticus (ie, having had a seizure that lasted longer than five minutes), prior epilepsy surgery, and having received three or more AEDs at the same time were significant predictors of SUDEP (odds ratios, 7.83, 4.23, and 4.7, respectively), whereas the other variables were not. The best model used number of AEDs and prior epilepsy surgery (AUC, 0.855). The second-best model used number of AEDs and prior status epilepticus (AUC, 0.839). The third-best model used number of AEDs alone (AUC, 0.807).

Yong Park, MD


The risk factors likely reflect epilepsy that is difficult to control. Many of the patients who underwent surgery continued to have frequent seizures, which suggests that unsuccessful surgery might increase SUDEP risk through unknown mechanisms, the researchers said. Although surgery and number of medications were associated with increased SUDEP risk, this finding “does not mean that people with epilepsy should not continue with those treatments, which may be key to helping control seizures and improving quality of life,” said Yong Park, MD, senior author of the study and Professor and Chair of Child Neurology at Medical College of Georgia at Augusta University. “Rather, our findings help identify those who may be at high risk and should be watched closely, such as by being monitored at night when SUDEP is most likely to occur.”

Rituximab May Provide Greater Benefits Than Other First-Line MS Therapies

Article Type
Changed
Thu, 12/15/2022 - 15:52
The drug appears to be associated with a higher likelihood of adherence and a lower rate of relapse.

Rituximab is associated with a lower drug discontinuation rate than all other commonly prescribed disease-modifying treatments (DMTs) used as initial therapy for relapsing-remitting multiple sclerosis (MS), according to a retrospective study of patient data from a Swedish MS registry.

In addition, relapse rates were lower with rituximab (Rituxan) than they were with injectable DMTs and dimethyl fumarate (Tecfidera), according to the study, which was published online ahead of print January 8 in JAMA Neurology.

The results suggest that rituximab “can be considered an option” for treatment-naive patients with relapsing-remitting MS, according to Mathias Granqvist, MD, a graduate student in the Department of Clinical Neuroscience at the Karolinska Institute in Stockholm, and his coauthors.

Anti-CD20 agents such as rituximab are “likely to become an additional treatment option” for relapsing-remitting MS, and off-label use of rituximab for this indication has “increased considerably” in Sweden in recent years, the investigators said. Relapsing-remitting MS is not an approved indication for rituximab in the United States, but in Sweden “there is no difference in reimbursement policy ... because all DMTs are covered by the national health insurance, including off-label medications.”

The emergence of new DMTs for relapsing-remitting MS has changed the treatment landscape recently, although in real-world practice, there is a lack of “detailed knowledge about how to tailor therapy,” the authors said. They noted that the majority of patients discontinue traditional first-line treatment with injectable DMTs (ie, interferon beta and glatiramer acetate) within two years, suggesting a need for better treatment options.

To evaluate the real-world effectiveness of rituximab in this setting, Dr. Granqvist and his colleagues selected patient registry data for two Swedish counties that included 494 participants who received a diagnosis of relapsing-remitting MS between January 1, 2012, and October 31, 2015.

The largest subset of patients (215) received injectable DMTs, while 120 received rituximab, 86 received dimethyl fumarate, 50 received natalizumab (Tysabri), 17 received fingolimod (Gilenya), and six received other treatments, according to the authors.

The proportion of patients who stayed on treatment was significantly higher for rituximab versus all other DMTs. Compared with rituximab, the hazard ratios for drug discontinuation, after adjusting for covariates and propensity score, were 11.4 for injectable DMTs, 15.1 for dimethyl fumarate, 5.9 for fingolimod, and 11.3 for natalizumab.

Rituximab-treated patients also had lower rates of clinical relapse, neuroradiologic disease activity, and adverse events, compared with patients who received injectable DMTs or dimethyl fumarate, according to the investigators.

In comparison with fingolimod and natalizumab, rituximab was associated with lower relapse rates and fewer gadolinium-enhancing lesions, but those differences did not reach statistical significance in all analyses.

The drug appears to be associated with a higher likelihood of adherence and a lower rate of relapse.

Rituximab is associated with a lower drug discontinuation rate than all other commonly prescribed disease-modifying treatments (DMTs) used as initial therapy for relapsing-remitting multiple sclerosis (MS), according to a retrospective study of patient data from a Swedish MS registry.

In addition, relapse rates were lower with rituximab (Rituxan) than they were with injectable DMTs and dimethyl fumarate (Tecfidera), according to the study, which was published online ahead of print January 8 in JAMA Neurology.

The results suggest that rituximab “can be considered an option” for treatment-naive patients with relapsing-remitting MS, according to Mathias Granqvist, MD, a graduate student in the Department of Clinical Neuroscience at the Karolinska Institute in Stockholm, and his coauthors.

Anti-CD20 agents such as rituximab are “likely to become an additional treatment option” for relapsing-remitting MS, and off-label use of rituximab for this indication has “increased considerably” in Sweden in recent years, the investigators said. Relapsing-remitting MS is not an approved indication for rituximab in the United States, but in Sweden “there is no difference in reimbursement policy ... because all DMTs are covered by the national health insurance, including off-label medications.”

The emergence of new DMTs for relapsing-remitting MS has changed the treatment landscape recently, although in real-world practice, there is a lack of “detailed knowledge about how to tailor therapy,” the authors said. They noted that the majority of patients discontinue traditional first-line treatment with injectable DMTs (ie, interferon beta and glatiramer acetate) within two years, suggesting a need for better treatment options.

To evaluate the real-world effectiveness of rituximab in this setting, Dr. Granqvist and his colleagues selected patient registry data for two Swedish counties that included 494 participants who received a diagnosis of relapsing-remitting MS between January 1, 2012, and October 31, 2015.

The largest subset of patients (215) received injectable DMTs, while 120 received rituximab, 86 received dimethyl fumarate, 50 received natalizumab (Tysabri), 17 received fingolimod (Gilenya), and six received other treatments, according to the authors.

The proportion of patients who stayed on treatment was significantly higher for rituximab versus all other DMTs. Compared with rituximab, the hazard ratios for drug discontinuation, after adjusting for covariates and propensity score, were 11.4 for injectable DMTs, 15.1 for dimethyl fumarate, 5.9 for fingolimod, and 11.3 for natalizumab.

Growing Nodule on the Arm

The Diagnosis: Primary Cutaneous Anaplastic Large Cell Lymphoma

Primary cutaneous CD30+ lymphoproliferative disorders encompass lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma (PCALCL) as well as borderline cases. Primary cutaneous anaplastic large cell lymphoma is a rare disease that is more common in white patients with slight male predominance and median age at diagnosis of 61 years.1 Prognosis is excellent, with a 90% survival rate at 10 years. Although lesions spontaneously regress in 6% to 22% of cases, complete resolution is rare.2 Clinically, the classic presentation is a solitary, rapidly growing, flesh-colored, erythematous nodule or plaque on the arms and legs or trunk, often with ulceration. Proper diagnosis requires clinical, histopathologic, and immunophenotypic correlation.

Histopathologic examination of PCALCL typically reveals large, atypical, Reed-Sternberg-like cells most commonly with anaplastic cytomorphology, but pleomorphic or immunoblastic morphology is not uncommon. Cells are in sheets or nodules, diffusely occupying the dermis and often the subcutaneous fat, with more than 75% of large cells expressing CD30.3 In addition to CD30 positivity, immunophenotype is classically CD4+, cutaneous lymphocyte-associated antigen positive, epithelial membrane antigen negative, and anaplastic lymphoma kinase negative; CD2, CD5, and CD3 expression is variable. Interestingly, in our case, there was a minor population of CD8+ cells. CD8 expression is seen in less than 5% of PCALCL cases; this phenotype is associated with an indolent disease with favorable prognosis.3 Of note, anaplastic lymphoma kinase positivity corresponding to a t(2;5) translocation is more suggestive of systemic anaplastic large cell lymphoma with secondary skin involvement and more commonly is seen in children. For reasons possibly related to mediators such as epidermal growth factor or transforming growth factor α from CD30+ cells, epidermal hyperplasia can be seen in PCALCL.4 The subsequent hyperkeratosis, crusting, and ulceration can be difficult to distinguish from lesions such as pyoderma gangrenosum, squamous cell carcinoma, arthropod bite, leukemia cutis, Merkel cell carcinoma (MCC), and metastatic breast cancer.

Skin involvement with leukemia is rare but most commonly is seen in acute myelogenous leukemia, specifically more mature forms such as acute myelomonocytic leukemia and acute monocytic leukemia. Approximately 10% to 20% of acute myelomonocytic leukemia cases have cutaneous involvement.5 Although there is a variety of potential skin lesions, the most common is a red-purple papule or nodule, sometimes with hemorrhage or ulceration, on the head, neck, and trunk. Leukemic infiltrates may arise from sites of prior trauma. Histopathology depends on the type of leukemia; however, general features include a normal epidermis without epidermotropism and perivascular, nodular, or diffuse infiltrate of neoplastic cells in the dermis, often with a Grenz zone (Figure 1). Compared to PCALCL, leukemia cutis shows sparing of the papillary dermis (Grenz zone), and the cells have more cytoplasm and show a different immunophenotype. The cells often are fragile and show crush artifact. Acute myelogenous leukemia often will show cytoplasmic granules; however, immature precursor cells may not have granules. The myeloid cells will stain with myeloperoxidase and chloroacetate. Positivity is seen for CD13, CD33, and CD68. Clinical correlation is important because other diseases with nodular or diffuse infiltrates of small cell infiltrates, such as extramedullary hematopoiesis and lymphoma, appear similar. Acute myelogenous leukemia is associated with neutrophilic dermatoses such as Sweet syndrome and pyoderma gangrenosum. Cutaneous eruption resolves with successful treatment of the leukemia.

Figure 1. Diffuse infiltrate of monotonous large cell population with high nuclear to cytoplasmic ratio in the setting of myeloid-type leukemia cutis. Cells are round with slightly irregular nuclear contours, finely dispersed chromatin, and prominent nucleoli (H&E, original magnification ×20).

Breast cancer is the most common cancer to metastasize to the skin in women, accounting for 73% of cutaneous metastases, followed by melanoma, which is responsible for 11%.5 The classic presentation is an erythematous patch with spreading borders or a nodule on the trunk. Many cases of metastatic breast cancer with skin involvement may represent direct extension of the cancer into the skin. General histologic clues to cutaneous metastasis include well-circumscribed dermal or subcutaneous nodules of atypical cells with an increase in mitotic activity without connection to the epidermis. Tumor cells may show diffuse, nodular, or single file pattern and may exhibit areas of necrosis. Ductal carcinoma additionally may show ductal or glandular differentiation with surrounding desmoplasia (Figure 2). Immunohistochemistry typically is positive for cytokeratin (CK) 7, estrogen receptor/progesterone receptor, mammaglobin, and gross cystic disease fluid protein-15, and negative for CK20, CK5/6, and thyroid transcription factor-1.

Figure 2. Cutaneous metastatic invasive ductal adenocarcinoma of the breast exhibits cords of cohesive pleomorphic epithelioid cells invading the dermis with apparent desmoplastic reaction (H&E, original magnification ×10).

Papulovesicular and nodular lesions appearing as an arthropod bite have been noted in hematologic malignancies, underscoring the importance of histopathology and clinical correlation. Arthropod bites commonly present as red papules, nodules, vesicles, or pustules at the site of the bite. Pseudolymphomatous nodules occasionally develop. Excoriations and further progression to persistent prurigo also may occur. Histopathology shows variable epidermal features including spongiosis, acanthosis, parakeratosis, dermal edema, and superficial and deep perivascular neutrophils (Figure 3). Additionally, lymphocytes sometimes with CD30 positivity may be seen. The presence of eosinophils in interstitial areas, especially in the deep dermis, is a useful clue.

Figure 3. Perivascular mixed inflammatory infiltrate composed of lymphocytes, histiocytes, eosinophils, and neutrophils in the setting of an arthropod bite (H&E, original magnification ×10).

Lack of staining for epithelial and neuroendocrine markers differentiates PCALCL from MCC; specifically CK20, an epithelial marker positive in more than 90% of MCC cases, excludes lymphoma.6 Merkel cell carcinoma presents as a solitary, quickly growing, red and often ulcerated nodule or plaque on the head, neck, or legs of elderly patients. The lesions often are in areas of sun damage. Histopathology classically shows a diffuse dermal infiltrate of monotonous round blue cells with a scant cytoplasmic rim and multiple inconspicuous nucleoli in nests, rosettes, or strands in the dermis. There are frequent mitotic figures. The cells are uniform and 2 to 3 times larger than mature lymphocytes. Single-cell necrosis and crush artifact is common. Epidermotropism or coexisting Bowenoid change also may be observed (Figure 4). The term primary neuroendocrine carcinoma of the skin is preferred over Merkel cell carcinoma because the tumor cells share similar morphology to the specialized touch receptor of the basal layer (Merkel cell), but no direct histogenetic relationship has been established.7,8

Figure 4. Nodular infiltrate of monotonous small cells in Merkel cell carcinoma can appear hematopoietic, necessitating neuroendocrine and epithelial stains. Tumor cells have scant cytoplasm, vesicular nuclei with finely granular and dusty chromatin, single cell apoptosis, and frequent mitoses (H&E, original magnification ×20).

Immunohistochemistry is key to diagnosis because MCC stains for both epithelial and neuroendocrine markers. Positivity is seen for neuron-specific enolase, epithelial membrane antigen, neurofilament, synaptophysin, and chromogranin. Because the histology of MCC may resemble small cell carcinoma of the lung, staining for low-molecular-weight keratin such as CK20 and CK7 help to distinguish MCC. Merkel cell carcinoma typically is CK20+ and CK7-, while small cell carcinoma of the lung is the opposite.9 The tumor grows aggressively and metastasis is common, thus surgery is the primary approach, but adjuvant chemotherapy and radiation often are given in addition.

There are frequent mitotic figures. The cells are uniform and 2 to 3 times larger than mature lymphocytes. Single-cell necrosis and crush artifact is common. Epidermotropism or coexisting Bowenoid change also may be observed (Figure 4). The term primary neuroendocrine carcinoma of the skin is preferred over Merkel cell carcinoma because the tumor cells share similar morphology to the specialized touch receptor of the basal layer (Merkel cell), but no direct histogenetic relationship has been established.7,8

Figure 4. Nodular infiltrate of monotonous small cells in Merkel cell carcinoma can appear hematopoietic, necessitating neuroendocrine and epithelial stains. Tumor cells have scant cytoplasm, vesicular nuclei with finely granular and dusty chromatin, single cell apoptosis, and frequent mitoses (H&E, original magnification ×20).

Immunohistochemistry is key to diagnosis because MCC stains for both epithelial and neuroendocrine markers. Positivity is seen for neuron-specific enolase, epithelial membrane antigen, neurofilament, synaptophysin, and chromogranin. Because the histology of MCC may resemble small cell carcinoma of the lung, staining for low-molecular-weight keratin such as CK20 and CK7 help to distinguish MCC. Merkel cell carcinoma typically is CK20+ and CK7-, while small cell carcinoma of the lung is the opposite.9 The tumor grows aggressively and metastasis is common, thus surgery is the primary approach, but adjuvant chemotherapy and radiation often are given in addition.

H&E, original magnification ×4 (inset, original magnification ×40).

A 65-year-old white woman presented with an asymptomatic bump on the left upper arm of 4 months' duration that arose following a cat scratch. Physical examination was notable for a 35×30-mm, firm, ulcerated, exophytic nodule. Histologic examination demonstrated an ulcerated epidermis and a dense basophilic infiltrate occupying the entire dermis and extending to the subcutaneous tissue. Higher magnification (inset) demonstrated a pleomorphic population of medium- to large-sized discohesive round cells containing variable amounts of slightly eosinophilic cytoplasm, irregular nuclear contours, and prominent nucleoli. Scattered atypical mitotic figures were identified. CD30, CD4, leukocyte common antigen, and Ki-67 immunostains were strongly and diffusely positive. Notable negative stains included anaplastic lymphoma kinase, synaptophysin, epithelial membrane antigen, neuron-specific enolase, CD20, and S-100.

VIDEO: What to monitor during isotretinoin treatment

Article Type

Tue, 04/30/2019 - 09:11

– Hilary Baldwin, MD, medical director of the Acne Treatment and Research Center, Morristown, N.J., recently changed how she monitors patients on isotretinoin.

The latest research indicates that ongoing CBCs really aren’t necessary, and that GGT (gamma-glutamyl transferase), which is liver specific, is a far better option than ALT/AST to keep tabs on the liver. Creatine kinase can’t be ignored, either, especially in young, athletic patients, because of the risk of rhabdomyolysis.

In a video interview at the Hawaii Dermatology Seminar provided by Global Academy for Medical Education/Skin Disease Education Foundation, Dr. Baldwin explained the thinking behind her new approach, plus what else needs to be monitored and for how long – and the level of creatine kinase that should raise a red flag for clinicians.

Dr. Baldwin is a speaker, advisor, and/or investigator for a number of companies, including Allergan, Galderma, and La Roche Posay.

Mobile Medical Apps for Patient Education: A Graded Review of Available Dermatology Apps

According to industry estimates, roughly 64% of US adults were smartphone users in 2015.1 Smartphones enable users to utilize mobile applications (apps) that can perform a variety of functions in many categories, including business, music, photography, entertainment, education, social networking, travel, and lifestyle. The widespread adoption and use of mobile apps has implications for medical practice. Mobile apps have the capability to serve as information sources for patients, educational tools for students, and diagnostic aids for physicians.2 Consequently, a number of medical and health care–oriented apps have already been developed3 and are increasingly utilized by patients and providers.4

Given its visual nature, dermatology is particularly amenable to the integration of mobile medical apps. A study by Brewer et al5 identified more than 229 dermatology-related apps in categories ranging from general dermatology reference, self-surveillance and diagnosis, disease guides, educational aids, sunscreen and UV recommendations, and teledermatology. Patients served as the target audience and principal consumers of more than half of these dermatology apps.5

Mobile medical and health care apps demonstrate great potential for serving as valuable information sources for patients with dermatologic conditions; however, the content, functions, accuracy, and educational value of dermatology mobile apps are not well characterized, making it difficult for patients and health care providers to select and recommend appropriate apps.6 In this study, we created a rubric to objectively grade 44 publicly available mobile dermatology apps with the primary focus of patient education.

Methods

We conducted a search of dermatology-related educational mobile apps that were publicly available via the App Store (Apple Inc) from January 2016 to November 2016. (The pricing, availability, and other features of these apps may have changed since the study period.) The following search terms were used: dermatology, dermoscopy, melanoma, skin cancer, psoriasis, rosacea, acne, eczema, dermal fillers, and Mohs surgery. We excluded apps that were not in English; had a solely commercial focus; were mobile textbooks or scientific journals; were used to provide teledermatology services with no educational purpose; were solely focused on homeopathic, alternative, and/or complementary medicine; or were intended primarily as a reference for students or health care professionals. Our search yielded 44 apps with patient education as a primary objective. The apps were divided into 6 categories based on their focus: general dermatology, cosmetic dermatology, acne, eczema, psoriasis, and skin cancer.

Each app was reviewed using a quantified grading rubric developed by the researchers. In a prior evaluation, Handel7 reviewed 35 health and wellness mobile apps utilizing the categories of ease of use, reliability, quality, scope of information, and aesthetics.4 These criteria were modified and adapted for the purposes of this study, and a 4-point scale was applied to each criterion. The final criteria were (1) educational objectives, (2) content, (3) accuracy, (4) design, and (5) conflict of interest. The quantified grading rubric is described in Table 1.

Results

The possible range of scores based on the grading rubric was 5 to 20. The actual range of scores was 8 to 19 (Table 2). The 44 reviewed apps were categorized by topic as acne, cosmetic dermatology, eczema, general dermatology, psoriasis, or skin cancer. A sample of 15 apps selected to represent the distribution of scores and their grading on the rubric are presented in Table 3.

Comment

The number of dermatology-related apps available to mobile users continues to grow at an increasing rate.8 The apps vary in many aspects, including their purpose, scope, intended audience, and goals of the app publisher. In turn, more individuals are turning to mobile apps for medical information,4 especially in dermatology, thus it is necessary to create a systematic way to evaluate the quality and utility of each app to assist users in making informed decisions about which apps will best meet their needs in the midst of a wide array of choices.

For the purpose of this study, an objective rubric was created that can be used to evaluate the quality of medical apps for patient education in dermatology. An app’s adequacy and usefulness for patient education was thought to depend on 3 possible score ranges into which the app could fall based on the grading rubric. An app with a total score in the range of 5 to 10 was not thought to be useful and may even be detrimental to patients. An app with a total score in the range of 11 to 15 may be used for patient education with some reservations based on shortcomings for certain criteria. An app with a score in the range of 16 to 20 was thought to be valuable and adequate for patient education. For example, the How to Treat Acne app received a total score of 8 and therefore would not be recommended to patients based on the grading rubric used in this study. This particular app provided sparse and sometimes inaccurate information, had a confusing user interface, and contained many obstructive advertisements. In contrast, the Eczema Doc app received a total score of 19, which indicates a quality app deemed to be useful for patient information based on the established rubric. This app met all the objectives that it advertised, contained accurate information with verified citation of sources, and was very easy for users to navigate.

Of the 44 graded apps, only 9 (20.5%) received scores in the highest range of 16 to 20, which indicates a need for improvements in mobile dermatology apps intended for patient education. Adopting the grading rubric developed in this study as a standard in the creation of medical apps could have beneficial implications in disseminating accurate, safe, unbiased, and easy-to-understand information to patients.

VIDEO: Rivaroxaban plus aspirin halves ischemic strokes

– Combined treatment with a low dosage of the anticoagulant rivaroxaban plus aspirin cut the incidence of ischemic strokes nearly in half, compared with aspirin alone, in a multicenter, randomized trial of more than 27,000 patients with stable atherosclerotic vascular disease.

This dramatic reduction in ischemic strokes as well as in all-cause strokes by adding low-dose rivaroxaban(Xarelto) occurred without any significant increase in hemorrhagic strokes but with a small increase in total major bleeding events, such as gastrointestinal bleeds, Mike Sharma, MD, said at the International Stroke Conference, sponsored by the American Heart Association.

“There was a consistent effect across all strata of stroke risk. For patients who had a prior stroke, it’s pretty clear to use rivaroxaban plus aspirin because it had a big benefit” with no increase in intracranial hemorrhages, Dr. Sharma said in a video interview.

“We think these results will fundamentally change how we approach stroke prevention,” added Dr. Sharma, a stroke neurologist in the Population Health Research Institute of McMaster University in Hamilton, Ont.

The results he reported came from a secondary analysis of data collected in the COMPASS (Rivaroxaban for the Prevention of Major Cardiovascular Events in Coronary or Peripheral Artery Disease) trial, which enrolled 27,395 patients with stable coronary or peripheral artery disease at 602 centers in 33 countries.

The primary outcome of the trial, reported in 2017, was the combined rate of cardiovascular death, MI, or stroke during an average 23 months of follow-up, which occurred in 4.1% of patients treated with 2.5 mg rivaroxaban twice daily plus 100 mg aspirin once daily, 4.9% of patients who received 5.0 mg rivaroxaban twice daily, and 5.4% in patients who received 100 mg aspirin daily, a statistically significant 24% relative risk reduction in the combined treatment group, compared with aspirin only. The rivaroxaban only–treated patients did not significantly differ from the control patients who received only aspirin (N Engl J Med. 2017 Oct 5;377[14]:1319-30). The main results showed a 1.2% increase in the rate of major bleeds in patients treated with rivaroxaban plus aspirin, compared with aspirin only, but the rate of nonfatal symptomatic intracranial hemorrhages was identical in the two treatment groups.

The new results Dr. Sharma reported at the conference focused on various measures of stroke. The rate of all strokes was 42% lower among the patients treated with rivaroxaban plus aspirin, compared with the aspirin alone patients, and ischemic strokes were 49% lower with the dual therapy, compared with aspirin only. Both differences were statistically significant. In contrast, the rivaroxaban alone regimen did not significantly reduce all-cause strokes. It did significantly reduce ischemic strokes, compared with aspirin only, but it also significantly increased hemorrhagic strokes, compared with aspirin only, an adverse effect not caused by the combination of low-dose rivaroxaban plus aspirin.

Rivaroxaban plus aspirin surpassed aspirin alone for preventing both mild and severe strokes and for preventing strokes both in patients with a history of a prior stroke and in those who never had a prior stroke. The stroke reduction produced by rivaroxaban plus aspirin was greatest in the highest risk patients – those with a prior stroke. On the combined regimen, these patients had an average stroke incidence of 0.7% per year, compared with an annual 3.4% rate among the patients on aspirin only, a 2.7% absolute reduction by using rivaroxaban plus aspirin that translated into a number needed to treat of 37 patients with a history of stroke to prevent one new stroke per year.

The 2017 report of the main COMPASS results included a net clinical benefit analysis that factored together the primary endpoint events and major bleeding events. The net rate of all these events was 4.7% with rivaroxaban plus aspirin and 5.9% with aspirin only, a statistically significant 20% relative risk reduction for all adverse outcomes with dual therapy. This net clinical benefit suggests that adding rivaroxaban has a cost-effective benefit. Assessment of rivaroxaban’s cost benefit in COMPASS is in process, Dr. Sharma said.

Rivaroxaban received Food and Drug Administration marketing approval in 2011 for preventing deep vein thrombosis and preventing stroke in patients with atrial fibrillation at dosages higher than what was used in COMPASS. The approved rivaroxaban dosage for preventing deep vein thrombosis is 10 mg/day, and 20 mg/day for preventing stroke in atrial fibrillation patients. The 2.5-mg formulation of rivaroxaban that was given twice daily had the best safety and efficacy in COMPASS, but it is not available now on the U.S. market, although it is available in Europe. Johnson & Johnson, which markets rivaroxaban globally with Bayer, submitted an application to the FDA in December for marketing approval of the 2.5-mg formulation in twice-daily dosing for use as in the COMPASS trial.

COMPASS was sponsored by Bayer, the company that markets rivaroxaban in collaboration with Johnson & Johnson. Dr. Sharma has been a consultant or adviser to Bayer, Bristol-Myers Squibb, Boehringer Ingelheim, and Daiichi-Sankyo.

US Dermatology Residency Program Rankings Based on Academic Achievement

Rankings of US residency programs based on academic achievement are a resource for fourth-year medical students applying for residency through the National Resident Matching Program. They also highlight the leading academic training programs in each medical specialty. Currently, the Doximity Residency Navigator (https://residency.doximity.com) provides rankings of US residency programs based on either subjective or objective criteria. The subjective rankings utilize current resident and recent alumni satisfaction surveys as well as nominations from board-certified Doximity members who were asked to nominate up to 5 residency programs in their specialty that offer the best clinical training. The objective rankings are based on measurement of research output, which is calculated from the collective h-index of publications authored by graduating alumni within the last 15 years as well as the amount of research funding awarded.1

Aquino et al2 provided a ranking of US dermatology residency programs using alternative objective data measures (as of December 31, 2008) from the Doximity algorithm, including National Institutes of Health (NIH) and Dermatology Foundation (DF) funding, number of publications by full-time faculty members, number of faculty lectures given at annual meetings of 5 societies, and number of full-time faculty members serving on the editorial boards of 6 dermatology journals. The current study is an update to those rankings utilizing data from 2014.

Methods

The following data for each dermatology residency program were obtained to formulate the rankings: number of full-time faculty members, amount of NIH funding received in 2014 (https://report.nih.gov/), number of publications by full-time faculty members in 2014 (http://www.ncbi.nlm.nih.gov/pubmed/), and the number of faculty lectures given at annual meetings of 5 societies in 2014 (American Academy of Dermatology, the Society for Investigative Dermatology, the American Society of Dermatopathology, the Society for Pediatric Dermatology, and the American Society for Dermatologic Surgery). This study was approved by the institutional review board at Kaiser Permanente Southern California.

The names of all US dermatology residency programs were obtained as of December 31, 2014, from FREIDA Online using the search term dermatology. An email was sent to a representative from each residency program (eg, residency program coordinator, program director, full-time faculty member) requesting confirmation of a list of full-time faculty members in the program, excluding part-time and volunteer faculty. If a response was not obtained or the representative declined to participate, a list was compiled using available information from that residency program’s website.

National Institutes of Health funding for 2014 was obtained for individual faculty members from the NIH Research Portfolio Online Reporting Tools expenditures and reports (https://projectreporter.nih.gov/reporter.cfm) by searching the first and last name of each full-time faculty member along with their affiliated institution. The search results were filtered to only include NIH funding for full-time faculty members listed as principal investigators rather than as coinvestigators. The fiscal year total cost by institute/center for each full-time faculty member’s projects was summated to obtain the total NIH funding for the program.

The total number of publications by full-time faculty members in 2014 was obtained utilizing a PubMed search of articles indexed for MEDLINE using each faculty member’s first and last name. The authors’ affiliations were verified for each publication, and the number of publications was summed for all full-time faculty members at each residency program. If multiple authors from the same program coauthored an article, it was only counted once toward the total number of faculty publications from that program.

Program brochures for the 2014 meetings of the 5 societies were reviewed to quantify the number of lectures given by full-time faculty members in each program.

Each residency program was assigned a score from 0 to 1.0 for each of the 4 factors of academic achievement analyzed. The program with the highest number of faculty publications was assigned a score of 1.0 and the program with the lowest number of publications was assigned a score of 0. The programs in between were subsequently assigned scores from 0 to 1.0 based on the number of publications as a percentage of the number of publications from the program with the most publications.

A weighted ranking scheme was used to rank residency programs based on the relative importance of each factor. There were 3 factors that were deemed to be the most reflective of academic achievement among dermatology residency programs: amount of NIH funding received in 2014, number of publications by full-time faculty members in 2014, and number of faculty lectures given at society meetings in 2014; thus, these factors were given a weight of 1.0. The remaining factor— total number of full-time faculty members—was given a weight of 0.5. Values were totaled and programs were ranked based on the sum of these values. All quantitative analyses were performed using an electronic spreadsheet program.

 

 

Results

The overall ranking of the top 20 US dermatology residency programs in 2014 is presented in Table 1. The top 5 programs based on each of the 3 factors most reflective of academic achievement used in the weighted ranking algorithm are presented in Tables 2 through 4.

 

Comment

The ranking of US residency programs involves using data in an unbiased manner while also accounting for important subjective measures. In a 2015 survey of residency applicants (n=6285), the 5 most important factors for applicants in selecting a program were the program’s ability to prepare residents for future training or position, resident esprit de corps, faculty availability and involvement in teaching, depth and breadth of faculty, and variety of patients and clinical resources.3 However, these subjective measures are difficult to quantify in a standardized fashion. In its ranking of residency programs, the Doximity Residency Navigator utilizes surveys of current residents and recent alumni as well as nominations from board-certified Doximity members.1

One of the main issues in utilizing survey data to rank residency programs is the inherent bias that most residents and alumni possess toward their own program. Moreover, the question arises whether most residents, faculty members, or recent alumni of residency programs have sufficient knowledge of other programs to rank them in a well-informed manner.

Wu et al4 used data from 2004 to perform the first algorithmic ranking of US dermatology programs, which was based on publications in 2001 to 2004, the amount of NIH funding in 2004, DF grants in 2001 to 2004, faculty lectures delivered at national conferences in 2004, and number of full-time faculty members on the editorial boards of the top 3 US dermatology journals and the top 4 subspecialty journals. Aquino et al2 provided updated rankings that utilized a weighted algorithm to collect data from 2008 related to a number of factors, including annual amount of NIH and DF funding received, number of publications by full-time faculty members, number of faculty lectures given at 5 annual society meetings, and number of full-time faculty members who were on the editorial boards of 6 dermatology journals with the highest impact factors. The top 5 ranked programs based on the 2008 data were the University of California, San Francisco (San Francisco, California); Northwestern University (Chicago, Illinois); University of Pennsylvania (Philadelphia, Pennsylvania); Yale University (New Haven, Connecticut); and Stanford University (Stanford, California).2

The current ranking algorithm is more indicative of a residency program’s commitment to research and scholarship, with an assumption that successful clinical training is offered. Leading researchers in the field also are usually known to be clinical experts, but the current data does not take into account the frequency, quality, or methodology of teaching provided to residents. Perhaps the most objective measure reflecting the quality of resident education would be American Board of Dermatology examination scores, but these data are not publically available. Additional factors such as the percentage of residents who received fellowship positions; diversity of the patient population; and number and extent of surgical, cosmetic, or laser procedures performed also are not readily available. Doximity provides board pass rates for each residency program, but these data are self-reported and are not taken into account in their rankings.1

The current study aimed to utilize publicly available data to rank US dermatology residency programs based on objective measures of academic achievement. A recent study showed that 531 of 793 applicants (67%) to emergency medicine residency programs were aware of the Doximity residency rankings.One-quarter of these applicants made changes to their rank list based on this data, demonstrating that residency rankings may impact applicant decision-making.5 In the future, the most accurate and unbiased rankings may be performed if each residency program joins a cooperative effort to provide more objective data about the training they provide and utilizes a standardized survey system for current residents and recent graduates to evaluate important subjective measures.

Conclusion

Based on our weighted ranking algorithm, the top 5 dermatology residency programs in 2014 were Harvard University (Boston, Massachusetts); University of California, San Francisco (San Francisco, California); Stanford University (Stanford, California); University of Pennsylvania (Philadelphia, Pennsylvania); and Emory University (Atlanta, Georgia).

There were 3 factors that were deemed to be the most reflective of academic achievement among dermatology residency programs: amount of NIH funding received in 2014, number of publications by full-time faculty members in 2014, and number of faculty lectures given at society meetings in 2014; thus, these factors were given a weight of 1.0. The remaining factor— total number of full-time faculty members—was given a weight of 0.5. Values were totaled and programs were ranked based on the sum of these values. All quantitative analyses were performed using an electronic spreadsheet program.

 

 

Results

The overall ranking of the top 20 US dermatology residency programs in 2014 is presented in Table 1. The top 5 programs based on each of the 3 factors most reflective of academic achievement used in the weighted ranking algorithm are presented in Tables 2 through 4.

 

Comment

The ranking of US residency programs involves using data in an unbiased manner while also accounting for important subjective measures. In a 2015 survey of residency applicants (n=6285), the 5 most important factors for applicants in selecting a program were the program’s ability to prepare residents for future training or position, resident esprit de corps, faculty availability and involvement in teaching, depth and breadth of faculty, and variety of patients and clinical resources.3 However, these subjective measures are difficult to quantify in a standardized fashion. In its ranking of residency programs, the Doximity Residency Navigator utilizes surveys of current residents and recent alumni as well as nominations from board-certified Doximity members.1

One of the main issues in utilizing survey data to rank residency programs is the inherent bias that most residents and alumni possess toward their own program. Moreover, the question arises whether most residents, faculty members, or recent alumni of residency programs have sufficient knowledge of other programs to rank them in a well-informed manner.

Wu et al4 used data from 2004 to perform the first algorithmic ranking of US dermatology programs, which was based on publications in 2001 to 2004, the amount of NIH funding in 2004, DF grants in 2001 to 2004, faculty lectures delivered at national conferences in 2004, and number of full-time faculty members on the editorial boards of the top 3 US dermatology journals and the top 4 subspecialty journals. Aquino et al2 provided updated rankings that utilized a weighted algorithm to collect data from 2008 related to a number of factors, including annual amount of NIH and DF funding received, number of publications by full-time faculty members, number of faculty lectures given at 5 annual society meetings, and number of full-time faculty members who were on the editorial boards of 6 dermatology journals with the highest impact factors. The top 5 ranked programs based on the 2008 data were the University of California, San Francisco (San Francisco, California); Northwestern University (Chicago, Illinois); University of Pennsylvania (Philadelphia, Pennsylvania); Yale University (New Haven, Connecticut); and Stanford University (Stanford, California).2

The current ranking algorithm is more indicative of a residency program’s commitment to research and scholarship, with an assumption that successful clinical training is offered. Leading researchers in the field also are usually known to be clinical experts, but the current data does not take into account the frequency, quality, or methodology of teaching provided to residents. Perhaps the most objective measure reflecting the quality of resident education would be American Board of Dermatology examination scores, but these data are not publically available. Additional factors such as the percentage of residents who received fellowship positions; diversity of the patient population; and number and extent of surgical, cosmetic, or laser procedures performed also are not readily available. Doximity provides board pass rates for each residency program, but these data are self-reported and are not taken into account in their rankings.1

The current study aimed to utilize publicly available data to rank US dermatology residency programs based on objective measures of academic achievement. A recent study showed that 531 of 793 applicants (67%) to emergency medicine residency programs were aware of the Doximity residency rankings.One-quarter of these applicants made changes to their rank list based on this data, demonstrating that residency rankings may impact applicant decision-making.5 In the future, the most accurate and unbiased rankings may be performed if each residency program joins a cooperative effort to provide more objective data about the training they provide and utilizes a standardized survey system for current residents and recent graduates to evaluate important subjective measures.

Conclusion

Based on our weighted ranking algorithm, the top 5 dermatology residency programs in 2014 were Harvard University (Boston, Massachusetts); University of California, San Francisco (San Francisco, California); Stanford University (Stanford, California); University of Pennsylvania (Philadelphia, Pennsylvania); and Emory University (Atlanta, Georgia).

Rankings of US residency programs based on academic achievement are a resource for fourth-year medical students applying for residency through the National Resident Matching Program. They also highlight the leading academic training programs in each medical specialty. Currently, the Doximity Residency Navigator (https://residency.doximity.com) provides rankings of US residency programs based on either subjective or objective criteria. The subjective rankings utilize current resident and recent alumni satisfaction surveys as well as nominations from board-certified Doximity members who were asked to nominate up to 5 residency programs in their specialty that offer the best clinical training. The objective rankings are based on measurement of research output, which is calculated from the collective h-index of publications authored by graduating alumni within the last 15 years as well as the amount of research funding awarded.1

Aquino et al2 provided a ranking of US dermatology residency programs using alternative objective data measures (as of December 31, 2008) from the Doximity algorithm, including National Institutes of Health (NIH) and Dermatology Foundation (DF) funding, number of publications by full-time faculty members, number of faculty lectures given at annual meetings of 5 societies, and number of full-time faculty members serving on the editorial boards of 6 dermatology journals. The current study is an update to those rankings utilizing data from 2014.

Methods

The following data for each dermatology residency program were obtained to formulate the rankings: number of full-time faculty members, amount of NIH funding received in 2014 (https://report.nih.gov/), number of publications by full-time faculty members in 2014 (http://www.ncbi.nlm.nih.gov/pubmed/), and the number of faculty lectures given at annual meetings of 5 societies in 2014 (American Academy of Dermatology, the Society for Investigative Dermatology, the American Society of Dermatopathology, the Society for Pediatric Dermatology, and the American Society for Dermatologic Surgery). This study was approved by the institutional review board at Kaiser Permanente Southern California.

The names of all US dermatology residency programs were obtained as of December 31, 2014, from FREIDA Online using the search term dermatology. An email was sent to a representative from each residency program (eg, residency program coordinator, program director, full-time faculty member) requesting confirmation of a list of full-time faculty members in the program, excluding part-time and volunteer faculty. If a response was not obtained or the representative declined to participate, a list was compiled using available information from that residency program’s website.

National Institutes of Health funding for 2014 was obtained for individual faculty members from the NIH Research Portfolio Online Reporting Tools expenditures and reports (https://projectreporter.nih.gov/reporter.cfm) by searching the first and last name of each full-time faculty member along with their affiliated institution. The search results were filtered to only include NIH funding for full-time faculty members listed as principal investigators rather than as coinvestigators. The fiscal year total cost by institute/center for each full-time faculty member’s projects was summated to obtain the total NIH funding for the program.

The total number of publications by full-time faculty members in 2014 was obtained utilizing a PubMed search of articles indexed for MEDLINE using each faculty member’s first and last name. The authors’ affiliations were verified for each publication, and the number of publications was summed for all full-time faculty members at each residency program. If multiple authors from the same program coauthored an article, it was only counted once toward the total number of faculty publications from that program.

Program brochures for the 2014 meetings of the 5 societies were reviewed to quantify the number of lectures given by full-time faculty members in each program.

Each residency program was assigned a score from 0 to 1.0 for each of the 4 factors of academic achievement analyzed. The program with the highest number of faculty publications was assigned a score of 1.0 and the program with the lowest number of publications was assigned a score of 0. The programs in between were subsequently assigned scores from 0 to 1.0 based on the number of publications as a percentage of the number of publications from the program with the most publications.

A weighted ranking scheme was used to rank residency programs based on the relative importance of each factor. There were 3 factors that were deemed to be the most reflective of academic achievement among dermatology residency programs: amount of NIH funding received in 2014, number of publications by full-time faculty members in 2014, and number of faculty lectures given at society meetings in 2014; thus, these factors were given a weight of 1.0. The remaining factor— total number of full-time faculty members—was given a weight of 0.5. Values were totaled and programs were ranked based on the sum of these values. All quantitative analyses were performed using an electronic spreadsheet program.

The overall ranking of the top 20 US dermatology residency programs in 2014 is presented in Table 1. The top 5 programs based on each of the 3 factors most reflective of academic achievement used in the weighted ranking algorithm are presented in Tables 2 through 4.

Practice Points

  • Dermatology is not among the many hospital-based adult specialties that are routinely ranked annually by US News & World Report.
  • In the current study, US dermatology residency programs were ranked based on various academic factors, including the number of full-time faculty members, amount of National Institutes of Health funding received in 2014, number of publications by full-time faculty members in 2014, and the number of faculty lectures given at annual meetings of 5 societies in 2014.

– Sometimes, older is better, according to Eric Simpson, MD, professor of dermatology at Oregon Health & Science University, Portland.

Dr. Simpson was a key investigator in trials that were the basis of dupilumab’s approval in 2017 for adults with moderate to severe atopic dermatitis (AD), but there’s still a role for cyclosporine and other old standbys, he said in a video interview at the Hawaii Dermatology Seminar, provided by Global Academy for Medical Education/Skin Disease Education Foundation.

He said he’s asked all the time how to pick a systemic treatment for AD when topicals aren’t doing the trick. In the interview, he explained how dupilumab (Dupixent) fits into the picture, and how to select the right systemic therapy for the right patient. There are not a lot of data yet pointing to one option over the others for first-line treatment; a lot of it comes down to clinical smarts and patient preference.

Dr. Simpson is a consultant and/or investigator for a number of companies, including Eli Lilly, Pfizer, Novartis, and dupilumab manufacturer, Regeneron.
