Full Guidelines-From the Medical Board of the National Psoriasis Foundation: Perioperative management of systemic immunomodulatory agents in patients with psoriasis and psoriatic arthritis.

BACKGROUND: Systemic immunomodulatory agents are indicated in the treatment of moderate-to-severe plaque psoriasis and psoriatic arthritis. Perioperative use of these medications may increase the risk of surgical site infection (SSI) and complication. OBJECTIVE: To evaluate the risk of SSI and complication in patients with chronic autoimmune inflammatory disease receiving immunomodulatory agents (tumor necrosis factor-alfa [TNF-α] inhibitors, interleukin [IL] 12/23 inhibitor, IL-17 inhibitors, IL-23 inhibitors, cytotoxic T-lymphocyte-associated antigen-4 costimulator, phosphodiesterase-4 inhibitor, Janus kinase inhibitors, tyrosine kinase 2 inhibitor, cyclosporine (CsA), and methotrexate [MTX]) undergoing surgery. METHODS: We performed a search of the MEDLINE PubMed database of patients with chronic autoimmune inflammatory disease on immune therapy undergoing surgery. RESULTS: We examined 48 new or previously unreviewed studies; the majority were retrospective studies in patients with rheumatoid arthritis and inflammatory bowel disease. CONCLUSION: For low-risk procedures, TNF-α inhibitors, IL-17 inhibitors, IL-23 inhibitors, ustekinumab, abatacept, MTX, CsA, and apremilast can safely be continued. For intermediate- and high-risk surgery, MTX, CsA, apremilast, abatacept, IL-17 inhibitors, IL-23 inhibitors, and ustekinumab are likely safe to continue; however, a case-by-case approach is advised. Acitretin can be continued for any surgery. There is insufficient evidence to make firm recommendations on tofacitinib, upadacitinib, and deucravacitinib.

Vaccination recommendations for adults receiving biologics and oral therapies for psoriasis and psoriatic arthritis: Delphi consensus from the medical board of the National Psoriasis Foundation.

BACKGROUND: For psoriatic patients who need to receive nonlive or live vaccines, evidence-based recommendations are needed regarding whether to pause or continue systemic therapies for psoriasis and/or psoriatic arthritis. OBJECTIVE: To evaluate literature regarding vaccine efficacy and safety and to generate consensus-based recommendations for adults receiving systemic therapies for psoriasis and/or psoriatic arthritis receiving nonlive or live vaccines. METHODS: Using a modified Delphi process, 22 consensus statements were developed by the National Psoriasis Foundation Medical Board and COVID-19 Task Force, and infectious disease experts. RESULTS: Key recommendations include continuing most oral and biologic therapies without modification for patients receiving nonlive vaccines; consider interruption of methotrexate for nonlive vaccines. For patients receiving live vaccines, discontinue most oral and biologic medications before and after administration of live vaccine. Specific recommendations include discontinuing most biologic therapies, except for abatacept, for 2-3 half-lives before live vaccine administration and deferring next dose 2-4 weeks after live vaccination. LIMITATIONS: Studies regarding infection rates after vaccination are lacking. CONCLUSION: Interruption of antipsoriatic oral and biologic therapies is generally not necessary for patients receiving nonlive vaccines. Temporary interruption of oral and biologic therapies before and after administration of live vaccines is recommended in most cases.

Mechanism of Action of Brodalumab May Correlate With Efficacy in Patients With Inflammatory Skin Diseases.

Biologic therapy is used for systemic treatment of multiple inflammatory conditions, including moderate-to-severe plaque psoriasis. Brodalumab is an interleukin-17 (IL-17) receptor A antagonist indicated for the treatment of moderate-to-severe plaque psoriasis in adult patients who are candidates for systemic therapy or phototherapy and have failed to respond or have lost response to other systemic therapies. The unique mechanism of action of brodalumab, which blocks signaling mediated by multiple IL-17 family members, may play a key role in the overall efficacy, including in patients whose disease did not respond to other biologics. In this narrative review, we discuss the mechanism of action of brodalumab in inflammatory skin conditions, exploring how it relates to clinical and real-world efficacy, rescued responses after IL-17A inhibitor failure, and improvements in mental health and quality of life.

Brodalumab: 4-Year US Pharmacovigilance Report.

Brodalumab is an interleukin-17 receptor A antagonist approved for the treatment of moderate-to-severe psoriasis in adults without response or with loss of response to other systemic therapies. Brodalumab carries a boxed warning in the United States regarding suicidal ideation and behavior, though no causal relationship has been established. Here, we summarize 4 years of pharmacovigilance data, from August 15, 2017, through August 14, 2021, reported to Ortho Dermatologics by US patients and healthcare providers. The most common AEs listed in the brodalumab package insert (incidence ≥1%) and AEs of special interest are described. Brodalumab exposure estimates were calculated using the time between the first prescription-dispensing authorization date and last prescription-dispensing authorization date. Data were collected from 4019 patients with an estimated brodalumab exposure of 4563 patient-years. The most common AE was arthralgia (115 events; 2.52 events per 100 patient-years). No completed suicides and no new suicidal attempts were reported. There were 102 cases with serious infections; however, no serious fungal infections (including no new cases of oral candidiasis) were reported. There were 26 COVID-19 cases, and 3 of the cases with comorbid conditions were fatal. There were no new cases of Crohn’s disease. Of 37 reported malignancies among 32 cases, none were deemed related to brodalumab. Four-year pharmacovigilance data are consistent with the established safety profile reported in long-term clinical trials and 3-year pharmacovigilance data.

Integrating Precision Medicine into Medical Dermatology Clinical Practice: An Expert Consensus Panel.

BACKGROUND: Precision medicine utilizes an individual’s genomics to improve diagnosis, prognosis, and therapy. The joint American Academy of Dermatology and National Psoriasis Foundation 2019 guidelines recognized the need to identify biomarkers that can predict the optimal biologic agent for an individual patient. This paper examines the current state of precision medicine in dermatology and how its use can improve outcomes in psoriasis. METHODS: A search of PubMed/MEDLINE using the terms precision medicine, personalized medicine, biomarkers, genomics, and dermatology was performed to identify relevant publications. An expert consensus panel was then convened to assign levels of evidence to each article using strength of recommendation taxonomy and create consensus statements requiring a two-thirds supermajority for agreement utilizing a modified Delphi approach. RESULTS: Thirteen articles met inclusion and exclusion criteria and were assigned levels of evidence. The panel created 10 consensus statements on how precision medicine can improve patient outcomes, all of which received a unanimous (6/6) vote. CONCLUSION: Choosing a biologic medication for psoriasis often relies on patient preference, provider preference, and a trial-and-error approach. Utilizing precision medicine tests such as Mind.Px can help providers identify biomarkers unique to a patient’s pathophysiology and choose the optimal medication through a targeted and evidence-based approach.

A systematic review on the economic burden of interstitial lung disease and the cost-effectiveness of current therapies.

BACKGROUND: The economic burden of interstitial lung disease (ILD) is unknown, limiting informed resource allocation and planning. We sought to conduct the first systematic review on the direct, indirect, and overall costs associated with ILD and to evaluate the cost-effectiveness of current therapies globally. METHODS: We conducted systematic reviews of ILD disease cost studies and cost-effectiveness analyses (CEAs) using MEDLINE, Embase, and Web of Science databases between 2000 and 2020. We compared ILD costs between countries according to the share of costs towards each country's respective gross domestic product (GDP) per capita. Costs are reported in 2020 USD. RESULTS: We identified 25 disease cost studies and 7 CEAs. The direct medical costs ranged between $1824 and $116,927 annually per patient (median $32,834; 14-180% of GDP per capita in Western countries). The leading drivers of direct costs were inpatient (55%), outpatient (22%), and medication costs (18%), based on pooled estimates. Annual indirect costs ranged from $7149 to $10,902 per employed patient (median $9607; 12-23% of GDP per capita). Among the 7 CEAs, only 1 study (14%) showed an ILD therapy (ambulatory oxygen) was cost-effective compared to best supportive care. CONCLUSION: The direct and indirect costs associated with ILD are consistently high in all countries with available data, with cost-effectiveness profiles of new therapies generally undesirable. Globally, the median total direct cost for ILD equates to 51% of a country's GDP per capita and has been increasing over time.

Pooled Analysis Demonstrating Superior Patient- Reported Psoriasis Treatment Outcomes for Calcipotriene/ Betamethasone Dipropionate Cream Versus Suspension/Gel.

BACKGROUND: Calcipotriene and betamethasone dipropionate (CAL/BDP) cream is a novel treatment of plaque psoriasis based on PAD™ Technology (PAD-cream) designed to improve patient reported treatment satisfaction and quality of life (QoL). METHOD: A pooled analysis of patient reported outcomes from two phase 3, multicenter, randomized, investigator-blind, active, and vehicle-controlled trials evaluating a total of 1271 patients with mild to moderate plaque psoriasis according to the Physician Global Assessment (PGA) scale. Products were applied once daily for 8 weeks. RESULTS: The proportion of patients evaluating their treatment to have improved by 2 grades to clear or very mild disease on the 5-grade Subject Global Assessment (SGA) scale, defined as SGA Success, was significantly higher in the CAL/BDP PAD-cream group compared to active comparator (CAL/BDP suspension/gel) (week 8, 44.2% vs 27.9%, P<0.0001). A Dermatology Life Quality Index (DLQI) score of 0 or 1, indicating no impact of disease on the patient's life, was obtained by 43.8% of patients at week 8 in the CAL/BDP cream group versus 34.2% in the CAL/BDP suspension/gel group (P=0.0005). CAL/BDP PAD-cream demonstrated significantly greater psoriasis treatment convenience compared to CAL/BDP suspension/gel at all studied time points, including questions addressing greasiness of the formulation and overall satisfaction of treatment. CONCLUSION: CAL/BDP PAD-cream is a novel topical treatment for psoriasis, which through PAD™ Technology offers substantial improvement in QoL and treatment satisfaction for patients. Given these data, CAL/BDP PAD-cream may lead to better adherence to treatment, which ultimately could result in better treatment outcomes in clinical practice.

Evolving Concepts in Psoriasis: Special Considerations for Patients With Skin of Color, Skin Barrier Dysfunction, and the Role of Adjunctive Skin Care.

BACKGROUND: Despite considerable advances in our understanding of the pathogenesis and treatment of psoriasis, data pertaining to racial/ethnic variations, effects on barrier function, and the potential role of adjunctive skin care are relatively limited. Knowledge gaps in the clinical presentation, quality-of-life impact, and approach to treating psoriasis in patients with skin color contribute to disparities in care. In addition, small studies suggest that using skincare products can reduce psoriasis symptoms, improve barrier function, and result in higher patient satisfaction, yet patients with psoriasis may underuse skincare products. This manuscript seeks to offer insights into these knowledge gaps and their potential treatment implications. METHODS: A structured literature search followed by a panel discussion and an online review process explored best clinical practices in treating psoriasis patients with skin of color and providing expert guidance for skincare use, including gentle cleansers and moisturizers. RESULTS: Racial/ethnic differences in genetic factors, clinical presentation, and disease burden in psoriasis have been reported. Underrecognition of these differences contributes to racial/ethnic health disparities for psoriasis patients in the US. Several studies have shown a greater quality-of-life impact with psoriasis among patients with skin of color. Although the published data are limited, some studies have identified differences in skin barrier properties and suggest a role for adjunctive skin care in the management of psoriasis. CONCLUSION: Further study is needed to understand racial/ethnic population variations in psoriasis and develop strategies to reduce disparities in care. Addressing alterations in skin barrier function observed in psoriasis may help to improve treatment outcomes and patient satisfaction. J Drugs Dermatol. 2022;21(10):1054-1060. doi:10.36849/JDD.7090.

Onset of Plaque Psoriasis Treatment Responses With Anti-IL-17/IL-23 Biologic Therapies.

BACKGROUND: The impact of psoriasis on quality of life arises from both physical symptoms, such as pain and pruritus, and the psychosocial effects of the often highly visible lesions. For patients with moderate-to-severe psoriasis seeking amelioration of these symptoms, time to onset of treatment response is an important consideration when determining an appropriate therapeutic approach with their healthcare provider. METHODS: In this review, we discuss the fluidity of the definition of rapid response and time-to-response expectations of patients with psoriasis receiving biologic therapies. Next, we focus on time to response of brodalumab, a human anti–interleukin-17 receptor A monoclonal antibody, in patients with moderate-to-severe psoriasis, as measured by the psoriasis area and severity index and the psoriasis symptom inventory. Brodalumab previously exhibited efficacy and safety in treatment of moderate-to-severe psoriasis in three phase 3 trials (AMAGINE-1/-2/-3), warranting further characterization of its ability to meet patient needs regarding rapidity of treatment response. Finally, we place time to response of brodalumab in the context of the current treatment landscape of biologic therapies for psoriasis (particularly those targeting the interleukin-17/interleukin-23 axis). RESULTS: Direct and indirect comparisons with other interleukin-targeting drugs support brodalumab’s more rapid onset of treatment effects, including skin clearance and relief of itch and pain. CONCLUSION: Brodalumab induces a rapid treatment response in patients with moderate-to-severe psoriasis and may promote earlier improvements in quality of life.

Review of the diagnosis and management of pediatric psychodermatologic conditions: Part I.

Pediatric psychodermatologic conditions encompass both primary dermatologic conditions with psychiatric comorbidities and primary psychiatric conditions with self-induced dermatologic manifestations. Detection, diagnosis, and management of primary psychiatric conditions with dermatologic manifestations are challenging due to patient-perceived stigma and lack of educational opportunities for dermatology providers. This two-part series highlights the most up-to-date evidence-based data and management techniques of some of the more common dermatoses of primary psychiatric conditions in children. Part I includes trichotillomania, skin-picking disorder, and onychophagia, and part II covers dermatitis artefacta, body dysmorphic disorder, and delusions of parasitosis by proxy, with special considerations for family dynamics.

How to improve the interface between dermatology and psychiatry: a review and expert suggestion regarding the management of delusional patients.

Psychodermatological problems are prevalent in dermatology practices. Among those, delusional infestation (DI) is the subject of one of the most challenging patient encounters practicing dermatologists may experience. This difficulty arises, at least partly, from the unavailability of psychiatric knowledge and skillset necessary to properly manage these patients, reflecting that most dermatology residency programs are unable to provide training in psychodermatology. This relates to the lack of faculty available with such expertise. This article reviews various suggestions made in the medical literature to try to improve this current unfortunate situation. However, the more common suggestion regarding organizing a multidisciplinary psychodermatologic clinic may be difficult to achieve as reflected by the scarcity of such clinics in the U.S. The authors offer alternative suggestions beyond the idea of organizing a multidisciplinary clinic.

Improving care for delusional infestation patients: What can dermatologists learn from an entomologist?

Delusional Infestation (DI), represents one of the most difficult patient encounters that dermatology practitioners may experience. It is common for DI patients to doctor shop. Thus, dermatologists are one of several disciplines that may encounter DI patients in their practices. Others include veterinarians, epidemiologists, emergency departments, mental health practitioners, and entomologists. In this article, entomologist, Dr. Gale E. Ridge, with extensive DI experience, was interviewed to find out what an entomologist's perspective has been and what we, the dermatology providers, can learn from that. This is followed by a discussion by the dermatology experts on how the experience of entomologists compares to our experience and what we can learn from them.

Cultural and biological factors in body dysmorphic disorder in East Asia.

Body dysmorphic disorder (BDD) can cause severe distress and impairment in many important areas of functioning. Although BDD has been well studied in Western populations, there is limited information on BDD in other cultures. In this review, we discuss the prevalence and presentation of BDD in East Asian countries and the significance of conducting further research in this particular group.

The use of Goeckerman therapy in managing erythrodermic psoriasis resistant to multiple medications.

Erythrodermic psoriasis is a relatively rare, more dangerous inflammatory variant of psoriasis associated with high morbidity and mortality. It can be exceptionally challenging to manage, defeating even the most experienced dermatologist's arsenal of treatment strategies. Goeckerman therapy, a regimen of ultraviolet B phototherapy and crude coal tar, has demonstrable efficacy in severe and recalcitrant plaque-type psoriasis. However, its utility in erythrodermic psoriasis has not been explored within the dermatology literature. Herein, we present a patient with a long-standing history of erythrodermic psoriasis refractory to eleven treatment modalities including four biologic agents, who had his erythroderma 'turned around' following Goeckerman therapy. 'Turned around' is used to describe dramatically reducing a patient's cutaneous inflammation so that previously recalcitrant disease can now respond to maintenance therapy. The importance of a one to three week 'cool down' period of topical corticosteroid therapy prior to phototherapy or crude coal tar use is highlighted in this case as well. Although Goeckerman therapy is no longer regularly used, it remains one of the most efficacious treatments available for intractable psoriasis, attracting patients from all over the country desperate for symptom relief. This case suggests it may be useful in 'turning around' extremely difficult-to-treat erythrodermic psoriasis as well.

Fixed Combination Calcipotriene and Betamethasone Dipropionate (Cal/BD) Foam for Beyond-Mild Psoriasis: A Possible Alternative to Systemic Medication.

Calcipotriene 0.005% plus betamethasone dipropionate 0.064% (Cal/BD) aerosol foam is a topical agent indicated for the treatment of plaque psoriasis. While topical treatments are typically reserved for milder disease, in clinical trials with Cal/BD foam, the vast majority of patients had beyond-mild psoriasis at baseline, and multiple studies (including subgroup analyses from randomized controlled trials and other small-scale studies) have demonstrated favorable outcomes with the use of Cal/BD foam in this population. The objective of this article is to review existing data on the efficacy, safety, and cost-effectiveness of Cal/BD foam used in patients with beyond-mild psoriasis, either alone as topical monotherapy or as adjunctive therapy. Practical recommendations for managing beyond-mild psoriasis with Cal/BD foam are also provided. J Drugs Dermatol. 2020;19(8): doi:10.36849/JDD.2020.5300.

Treatment of Plaque Psoriasis With an Excimer Laser Utilizing an Optimal Therapeutic UVB Dose Protocol.

Background: Traditionally, treatment with the excimer laser requires determining the minimal erythema dose on healthy skin or using plaque-based induration; however, these protocols often lead to underdosing of psoriatic plaques and reduced treatment efficacy. Objective: To prospectively evaluate the effect of the excimer laser on plaque psoriasis using an optimal therapeutic dose (OTD) protocol. Methods: Subjects with stable plaque psoriasis were tested with the Multi-Microdose (MMD) tip on the XTRAC excimer laser to determine a minimum blistering dose (MBD). Treatment was then initiated at 20% less than the MBD. A single psoriatic lesion was treated once weekly for up to 11 sessions. The change from baseline of the target lesion's modified psoriasis area severity index (mPASI), quality of life and safety were evaluated. Results: Thirteen subjects with a mean age of 48.9±14.9 years and Fitzpatrick skin types I-IV participated in the study. Target plaque mPASI significantly decreased at all time points relative to baseline with significant improvement by the second treatment. Patients reached mPASI-75 within 5±2 sessions. By the end of the study 92% of patients achieved mPASI-75. On average, patients maintained an mPASI score ≥50% for 60 days. Treatment was well tolerated with no erosions or hyperpigmentation. Erythema was the most common adverse event. Conclusion: The OTDTM protocol with the MMD® tip allows determining the optimal dose locally on the psoriatic plaque itself. Consequently, ineffectual dosing levels and treatments are minimized. The OTD protocol reduces treatment frequency from 2-3 times per week to once weekly.

Is Morgellons an organic disease? structural and functional abnormalities implicated in the pathophysiology of delusional infestation.

Little is known about the pathophysiology of delusional infestation (DI), a psychodermatologic condition in which patients have a fixed, false belief of being infested with parasites or inanimate material in their skin, despite lack of objective evidence. Because some delusional states, such as schizophrenia and psychotic state in bipolar disorder have been found to be associated with brain structural and functional abnormalities, a literature review was conducted to summarize available data on structural and functional abnormalities that are found to be associated with DI. A review of the literature found cases of brain imaging studies in patients with primary DI, as well as patients with secondary DI. Accumulating evidence from the studies reviewed suggests that dysfunction of the fronto-striato-thalamo-parietal network may explain how delusions manifest in DI and suggest that DI has an organic etiology. Abnormalities in the striato-thalamo-parietal network may cause false sensations of infestation through dysfunction in visuo-tactile regulation, whereas abnormalities in the frontal region may impair judgement. Delusional infestation patients also exhibit increased activation of brain structures implicated in itch processing. Furthermore, patients at high risk for cerebrovascular disease who present with secondary DI may benefit from brain imaging studies to rule out brain ischemic insult.

The impact of pediatric atopic dermatitis on families: A review.

BACKGROUND: Atopic dermatitis (AD) is an extremely common childhood disease, with considerable impact on the quality of life of affected children and their families. While pruritus is the hallmark symptom of this disease, AD has been well-documented to impact patients beyond physical symptoms, resulting in behavior problems, mood disorders, and sleep disturbance. OBJECTIVE: This literature review outlines how atopic dermatitis impacts the quality of life of families of children affected by AD. METHODS: A total of 3436 articles were identified via an online search of the MEDLINE health literature database and were screened for relevance to quality of life impacts on families with children affected by AD. RESULTS: Caring for children affected by AD can be an extremely time-consuming task that can impair personal relationships, decrease psychosocial functioning, and cause sleep loss among family members of affected patients. Additionally, AD may result in work absence or decreased work productivity for caregivers. Special diets, irritant and allergen avoidance strategies, and alternative therapies are commonly used by patients to manage their disease and require large amounts of family involvement. CONCLUSIONS: Atopic dermatitis can greatly decrease quality of life of families of affected children in various domains, including sleep, finances, and relationships. Early intervention and psychotherapy may be needed in some patients to address these quality of life impairments.

Phase 3 Studies Comparing Brodalumab with Ustekinumab in Psoriasis.

BACKGROUND: Early clinical studies suggested that the anti-interleukin-17 receptor A monoclonal antibody brodalumab has efficacy in the treatment of psoriasis. METHODS: In two phase 3 studies (AMAGINE-2 and AMAGINE-3), patients with moderate-to-severe psoriasis were randomly assigned to receive brodalumab (210 mg or 140 mg every 2 weeks), ustekinumab (45 mg for patients with a body weight ≤100 kg and 90 mg for patients >100 kg), or placebo. At week 12, patients receiving brodalumab were randomly assigned again to receive a brodalumab maintenance dose of 210 mg every 2 weeks or 140 mg every 2 weeks, every 4 weeks, or every 8 weeks; patients receiving ustekinumab continued to receive ustekinumab every 12 weeks, and patients receiving placebo received 210 mg of brodalumab every 2 weeks. The primary aims were to evaluate the superiority of brodalumab over placebo at week 12 with respect to at least a 75% reduction in the psoriasis area-and-severity index score (PASI 75) and a static physician's global assessment (sPGA) score of 0 or 1 (clear or almost clear skin), as well as the superiority of brodalumab over ustekinumab at week 12 with respect to a 100% reduction in PASI score (PASI 100). RESULTS: At week 12, the PASI 75 response rates were higher with brodalumab at the 210-mg and 140-mg doses than with placebo (86% and 67%, respectively, vs. 8% [AMAGINE-2] and 85% and 69%, respectively, vs. 6% [AMAGINE-3]; P<0.001); the rates of sPGA scores of 0 or 1 were also higher with brodalumab (P<0.001). The week 12 PASI 100 response rates were significantly higher with 210 mg of brodalumab than with ustekinumab (44% vs. 22% [AMAGINE-2] and 37% vs. 19% [AMAGINE-3], P<0.001). The PASI 100 response rates with 140 mg of brodalumab were 26% in AMAGINE-2 (P=0.08 for the comparison with ustekinumab) and 27% in AMAGINE-3 (P=0.007). Rates of neutropenia were higher with brodalumab and with ustekinumab than with placebo. Mild or moderate candida infections were more frequent with brodalumab than with ustekinumab or placebo. Through week 52, the rates of serious infectious episodes were 1.0 (AMAGINE-2) and 1.3 (AMAGINE-3) per 100 patient-years of exposure to brodalumab. CONCLUSIONS: Brodalumab treatment resulted in significant clinical improvements in patients with moderate-to-severe psoriasis. (Funded by Amgen; AMAGINE-2 and AMAGINE-3 ClinicalTrials.gov numbers, NCT01708603 and NCT01708629.).
