27478 Herpes zoster and immunosuppression among patients with psoriasis or psoriatic arthritis on drug therapy

Immune-mediated dermotologic conditions such as psoriasis (PsO) and psoriatic arthritis (PsA) are associated with risk of infections such as herpes zoster (HZ ) (Baumrim et al, 2019). To date, the association between medication classes and risk of HZ infection in this cohort remains poorly characterized. Through a retrospective analysis, we aimed to characterize patients with PsO or PsA who had confirmed HZ. We examined the concurrent PsO and PsA treatments including disease-modifying antirheumatic drugs (DMARDs) and/or biologics. From a total of 1181 PsO or PsA patients seen by dermatology between January 2011 and July 2020, 34 (2.9%) had confirmed HZ. Among those with HZ, 22 (64.7%) were female, 25 (73.5%) were white, and the median age was 57 years (interquartile range, IQR: 46-65). Seventeen patients (50%) had commercial insurance, 15 (44.1%) had Medicare, and 1 (2.9%) had Medicaid. Twenty-five (73.5%) patients had a history of DMARDs and/or biologics use. The most common DMARD was methotrexate (85%) and most common biologic class were the TNF-alpha inhibitors (63.2%). PsO and PsA patients commonly switch medications and we sought to asses association of drug class and temporality of HZ diagnosis. Interestingly, 16 (47.1%) patients were not on a DMARD nor biologic at the time of HZ diagnosis. Moreover, no specific medication was found to be more commonly associated with HZ diagnosis. Our study further highlights the importance of monitoring patients with psoriasis and psoriatic arthritis on immunomodulatory therapies for herpes zoster infection.

Real world effectiveness and satisfaction with secukinumab in the treatment of patients with psoriatic arthritis: a population survey in five European countries

Objectives To describe the effectiveness of secukinumab in the treatment of psoriatic arthritis (PsA) and associated physician satisfaction with secukinumab treatment, in routine clinical practice across five European countries. Methods A retrospective analysis of PsA patients receiving secukinumab for ≥4 months in France, Germany, Italy, Spain and the UK from March to December 2018. Data based on physician-completed questionnaires at initiation of treatment and at the data collection consultation were collected and used to assess effectiveness. Results 572 PsA patients with a mean age of 47.9 years, 57.0% were male, with 5.6% of patients with mild, 55.2% with moderate and 38.1% severe PsA prior to treatment initiation were included. 33.0% of patients received a dosage of 150 mg and 67.0% a dosage of 300 mg secukinumab. Around 84% of patients received secukinumab for 6 months or longer. Symptoms seen at current assessment in over 20% of patients were tender or swollen joints or psoriatic skin lesions. Between initiation of treatment and the current consultation, improvements in skin, joint and overall severity were reported. Physician satisfaction with secukinumab’s ability to control disease was very high during the study period, greater than 90%, and was seen irrespective of disease severity at initiation, prior biologic use, treatment duration, time since diagnosis or onset of symptoms, treatment history, and BMI. Conclusion Physicians were satisfied with the ability of secukinumab to control disease and it was effective in the treatment of PsA patients in routine clinical settings.

Association of physician specialty with psoriatic arthritis treatment and costs.

To describe current psoriatic arthritis treatment and costs by provider specialty using real-world claims data. Observational, retrospective cohort study of patients in the IBM MarketScan Commercial and supplemental Medicare databases. Eligible patients had newly diagnosed psoriatic arthritis with 12 months of continuous enrollment pre- and post index date for their initial claim. Patients were assigned to 1 of 5 provider specialty cohorts. During the 1-year follow-up period, we collected psoriatic arthritis treatment agent and regimen type and total annual medical and health care costs. We used multivariate regression models to determine the conditional associations of provider specialty with costs. A total of 2132 patients with incident psoriatic arthritis qualified. Most providers were rheumatologists (n = 1365; 64%). Rheumatologists commonly prescribed oral small molecules (methotrexate, 56.3% of prescriptions; sulfasalazine, 8.6%; apremilast, 7.0%) as the index therapy, whereas 23.8% of prescriptions were for tumor necrosis factor inhibitors (adalimumab, 14.2%; etanercept, 7.9%; and infliximab, 1.7%). Compared with other specialists, dermatologists prescribed biologics and other specialty drugs more frequently-adalimumab (32.7%), apremilast (14.3%), etanercept (11.6%), and ustekinumab (8.8%)-and methotrexate less frequently (30.6%). The greatest unadjusted median health care costs were observed among dermatologists ($45,548) compared with rheumatologists ($30,411), primary care physicians ($29,927), rheumatologists/dermatologists ($27,393), and other specialists ($27,774). However, after adjusting for patient-level factors, multivariate regression analyses found that provider specialty was not associated with higher health care costs. In patients with newly diagnosed psoriatic arthritis, physician specialty was associated with different medication choices but not costs.

High rates of therapeutic changes in patients with psoriatic arthritis receiving treatment with disease-modifying antirheumatic drugs: A cross-sectional study

Objectives To characterize treatment patterns for patients with psoriatic arthritis (PsA) currently receiving any disease-modifying antirheumatic drug (DMARD). Methods The Strategy for Psoriatic Arthritis In Germany (SPAIG) study was a retrospective observational study conducted from May to November 2017 at 46 rheumatology centers. Current and previous treatment data were collected at a single visit from adult patients with PsA and psoriasis who received DMARD treatment for ≥6 of the previous 12 months. The primary outcome was the proportion of patients receiving a biologic DMARD (bDMARD). Multinomial logistic regression analysis was used to evaluate associations between current characteristics and initial choice of therapy. Results Mean age of the 316 patients was 55.1 years and mean PsA disease duration was 9.9 years. PsA activity was generally comparable across treatment groups. In this cohort, 57.3% of patients were currently treated with bDMARDs, 37.7% with conventional synthetic DMARDs, and 4.4% with targeted synthetic DMARDs. Almost half (48.4%) of patients reported DMARD modifications in the previous 12 months. Specific comorbidities and patient/disease characteristics were associated with initial therapy. Conclusion DMARD treatment of PsA is frequently modified, suggesting the need for more effective therapies and assessment tools.

Blastomycosis Infection in the Setting of Immunosuppression with Concurrent Methotrexate and Adalimumab for Treatment of Psoriasis

Blastomycosis is a dimorphic fungi endemic to the Ohio/Mississippi Rivers and the Great Lakes that can infect immunocompetent and immunosuppressed individuals. Systemic fungal infections, such as histoplasmosis or blastomycosis, have often been reported in patients taking TNF-α inhibitors such as adalimumab. However, blastomycosis is significantly less common than histoplasmosis and no cases have been described in the literature. We report a case of systemic blastomycosis associated with adalimumab and methotrexate use for psoriasis and psoriatic arthritis treatment that required extensive treatment and discontinuation of both medications. To our knowledge, this is the first case of systemic blastomycosis associated with adalimumab and methotrexate treatment for psoriasis to be described in the literature.

Nonclinical genotoxicity and carcinogenicity profile of apremilast, an oral selective inhibitor of PDE4

Apremilast is an oral, selective small molecule inhibitor of phosphodiesterase-4 (PDE4) that has been approved for the treatment of active psoriatic arthritis, moderate to severe plaque psoriasis, and for patients with oral ulcers associated with Behçet's disease. Apremilast modulates the inflammatory cascade in cells by inhibiting PDE4, thus preventing the degradation of cyclic adenosine monophosphate, resulting in the upregulation of interleukin (IL)-10 and the downregulation of proinflammatory cytokines, including IL-23, interferon gamma (IFNγ), and tumor necrosis factor alpha (TNFα). Here, we evaluated the genotoxic and carcinogenic potential of apremilast using Good Laboratory Practice (GLP)-compliant in vitro and in vivo studies. Apremilast was not genotoxic in the genetic toxicology battery, as evaluated for mutagenicity in the Ames test up to concentrations of 5000 μg/plate, clastogenicity in cultured human peripheral blood lymphocytes up to concentrations of 700 ug/mL was in excess of the solubility limit in culture medium and not able to assess; and negative for the induction of micronuclei in the bone marrow micronucleus test in mice up to doses of 2000 mg/kg/day. Furthermore, apremilast did not increase the incidence of tumors in lifetime rat or mouse carcinogenicity studies up to the maximum tolerated dose. In summary, in non-clinical studies, apremilast is not genotoxic and is not carcinogenic.

Herpes zoster and Janus kinase inhibition in rheumatology and gastroenterology patients: managing risk and vaccination

Patients with chronic inflammatory diseases, such as rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ulcerative colitis (UC), have an increased risk of herpes zoster (HZ) infection, compared with the general population. This risk is further increased by the use of immunomodulatory therapies, with a higher incidence of HZ reported in patients receiving Janus kinase (JAK) inhibitors, compared with those receiving other immunomodulatory or biological therapies. Tofacitinib is an oral JAK inhibitor for the treatment of RA, PsA and UC. In this narrative review, we discuss the effects of tofacitinib and other JAK inhibitors on HZ risk in patients with RA, PsA and UC, and strategies for risk management. We also discuss current UK guidelines for HZ vaccination in healthy individuals and patients with chronic inflammatory diseases, consider selected international guidelines, and review current HZ vaccination strategies.

New possibilities of systemic therapy of plaque psoriasis with the IL23p19 inhibitor risankizumab

Introduction. There is a trend towards rising incidence of psoriasis and increase in the degree of incidence of severe, atypical and treatment-resistant clinical forms of psoriasis in the Russian Federation. In this regard, cases of early disability of patients and deterioration of their quality of life are recorded, which determines the medical and social significance of this disease. In the last few years, a much deeper understanding of the pathogenesis of psoriasis has been gained. This is especially true of the role of T-helper 17 cells, the role of the IL-23 cytokine in the development of the disease, which has resulted in the development of new classes of biological drugs, which creation introduced significant changes in the treatment of psoriasis that has become more effective, safer and convenient for patients. More new biologics undergo clinical trials and receive approvals with each passing year. Among them is risankizumab, interleukin-23 inhibitor, which is a safe and effective drug for the treatment of moderate to severe plaque psoriasis and psoriatic arthritis in adult patients. Interleukin-23 inhibitors are not required to be administered as often as interleukin-17 inhibitors and may have a more favourable safety profile without an increased risk of candidiasis or inflammatory bowel disease. Overall, these highly effective drugs contribute to the improvement of the long-term efficacy of psoriasis therapy due to relief of skin lesions and joint symptoms, as well as to the enhancement of patients’ quality of life and lengthening of remissions.Purpose. To analyse key information about risankizumab using the results of clinical trials published in the current scientific literature.Materials and methods. This analysis used literature sources from the international medical databases: PubMed, Cochrane Library, MEDLINE.Results. Presently, a number of phase III registrational trials of risankizumab in 2,109 patients with plaque psoriasis have been published: UltIMMa-1, UltIMMa-2, IMMvent and IMMhance, as well as an additional side by side comparative study of risankizumab with secukinumab (IMMerge) in 327 patients with plaque psoriasis. The results of these studies were used as the grounds for approval of risankizumab for the treatment of patients with moderate to severe plaque psoriasis and psoriatic arthritis by the Russian Ministry of Health on September 14, 2020. There have also been several reports of interim results of the open-label enhanced LIMMitless study, which included patients from pivotal studies. Our records show that the percentage of patients receiving risankizumab for 3 years (172 weeks) and maintaining PASI 90 and PASI 100 was 88 and 63%, respectively, and the percentage of those maintaining sPGA 0/1 was 88%.Conclusion. The analysed data showed that risankizumab is one of the most effective target drugs for the treatment of psoriasis and psoriatic arthritis, it has a favourable safety profile and a more convenient dosage regimen as compared with other genetically engineered biologic drugs (GEBD) (the recommended dose of Skyrizi is 150 mg (two 75 mg injections) administered by subcutaneous injection at week 0, week 4, and every 12 weeks thereafter).

PSY12 Experience with Apremilast in Treatment of Psoriatic Arthritis in US Clinical Practice; Assessments from Trio Health and the American Rheumatology Network (ARN)

As a PDE4 inhibitor, apremilast is a unique agent in the treatment armamentarium for psoriatic arthritis (PsA). It is the one targeted immune modulating (TIM) treatment that may be combined with csDMARDs, biologic therapies, or used as a monotherapy. Here we examined care for PsA in a large network of community rheumatologists focusing on use of apremilast relative to TNF inhibitors. This study analyzed patients diagnosed with PsA receiving apremilast monotherapy or TNF inhibitor monotherapy as initial targeted treatment between Jan 2014 to Nov 2019 with ≥6 months follow-up. Disease Assessment Scores (DAS) were calculated using CDAI or Rapid 3. As a surrogate for clinical effectiveness, we examined time from monotherapy initiation to modification or discontinuation, defined as either drug discontinuation or addition of a csDMARD or TIM, via KM analyses. Of 817 apremilast-treated patients, 378 (46%) had no prior observed PsA treatment, 205 (25%) had previous csDMARDs treatment alone, and 234 (29%) previously received other TIM therapies. 329 apremilast-treated patients and 2438 TNFi-treated patients were identified as receiving monotherapy with no prior TIM therapy. From the TNFi-group, a subset of 658 patients were selected based on propensity score matching. Characteristics for the apremilast monotherapy and TNFi monotherapy groups differed significantly for gender and age group but not for baseline disease severity. Median time from monotherapy initiation to initial modification or discontinuation was significantly different between apremilast (17.0 months) and TNFi (34.4 months, p=0.002). In subset analyses, these differences persisted among females (p = 0.03), males (p <0.001) and patients with severe baseline DAS (p=0.009), but not different among non-severe baseline DAS. Time to apremilast modification or discontinuation was significantly less than the matched TNFi group. However, when stratified by baseline DAS, those with low DAS had no difference in time to modification between apremilast and TNFi.

Unmet needs in psoriatic arthritis.

Psoriatic arthritis (PsA) is a chronic inflammatory arthritis with a highly variable clinical presentation that does not have a validated molecular or imaging test, making accurate diagnosis a challenge. Consequences of diagnostic delay include irreversible joint damage and significant morbidity. Over the past few decades, there have been major advances in the understanding and treatment of PsA, leading to more targeted therapies. However, there is no current method to predict optimal treatment strategy to achieve minimal disease activity and prevent medication-related adverse events in the management of early disease. PsA is also associated with other comorbidities that include metabolic syndrome and psychosocial burden; two areas that are often unaddressed in the clinical setting and have associated sequelae. This chapter focuses on key domains of unmet needs, which include diagnostic challenges, delay in diagnosis, prognostication systems and stratified medicine approaches and precision medicine strategies for established and emerging therapies.

Relative efficacy and safety of secukinumab and guselkumab for the treatment of active psoriatic arthritis: A network meta-analysis.

To determine the relative effectiveness and safety of doses of secukinumab and guselkumab in patients with active psoriatic arthritis (PsA). A Bayesian network meta-analysis was performed incorporating data from randomized controlled trials (RCTs) to evaluate the effectiveness and safety of secukinumab 150 mg, secukinumab 300mg, and guselkumab 100 mg every 4 weeks (Q4W) and guselkumab every 8 weeks (Q8W). Six RCTs, including 2,385 patients, fulfilled the inclusion criteria. The surface under the cumulative ranking curve (SUCRA) revealed that secukinumab 300mg had the highest probability of reaching a 20% American College of Rheumatology (ACR20) response rate, followed by secukinumab 150mg, guselkumab 100 mg Q4W, guselkumab 100 mg Q8W, and placebo. The ACR50 response rate revealed the same distribution pattern as the ACR20 response rate. The SUCRA rating, dependent on the psoriasis area and severity index of at least 75% (PASI75) response rate, showed that guselkumab 100 mg Q4W had the highest possibility of achieving the PASi75 response, followed by guselkumab 100 mg Q8W, secukinumab 300 mg, secukinumab 150 mg, and placebo. Safety analyses focused on serious adverse events (SAEs), adverse events (AEs), and withdrawals attributable to AEs that did not have statistically relevant variation in the respective intervention categories. Based on the ACR20 and ACR50 response rates, secukinumab 300 mg had the strongest response effectiveness, whereas guselkumab 100 mg Q4W was the most effective treatment strategy for PsA based on PASI75. However, there was little disparity between the treatment options with regard to SAEs.

Current treatments and recommendations for Psoriatic Arthritis.

The aims of treatment for psoriatic arthritis (PsA) are to control inflammation, normalise functions and impacts on patients and prevent complications of the disease and its treatment. Over the past decade, treatment options for PsA have expanded with the availability of many more novel therapeutic agents. However, the treatment decisions and pathways for the use of these drugs are not always straightforward. There is a need to tailor the choice of medication to the individual patient, taking into account the type of their disease and consideration of other factors such as their co-morbidities. A treat to target approach is recommended with the aim to get the patient into a state of remission or low disease activity (whichever target is chosen). Both European League Against Rheumatism (EULAR) and American College of Rheumatology (ACR) have recently published updated guidance in 2018-2019. In this section, we will summarise the evidence for therapies in PsA and review the similarities and differences in these two sets of recommendations.

Psoriatic arthritis.

Psoriatic arthritis (PsA) is a chronic inflammatory arthritis associated with psoriasis. It is found in approximately 10% of psoriatic patients in Japan. PsA mainly affects the peripheral joints, spine, and/or sacroiliac joints. Left untreated, there is progressive, irreversible bone destruction leading to joint deformation and dysfunction. Before the era of biologic treatments, the diagnosis of PsA was difficult and available treatments were limited. Over time the pathology of PsA has become better understood, and many treatments now exist. Early detection and treatment of impending joint deformities are necessary to avoid impairment of PsA patients' quality of life. Most patients develop the arthritis following the onset of the skin manifestations of psoriasis. The process of diagnosing PsA sometimes encounters difficulties because some patients may not show radiographic findings in the early stage, and may have normal levels of C-reactive protein and matrix metalloproteinase-3. For these cases, approaches such as magnetic resonance imaging or ultrasound imaging, as well as symptom questionnaires, are helpful. Currently, non-steroidal anti-inflammatory drugs, disease-modifying antirheumatic drugs, and several biologics are the main treatments for PsA, which when used with an aggressive approach, will result in better patient outcomes.

What Has Changed in the Treatment of Psoriatic Arthritis After COVID-19?

Coronavirus disease 2019 is a respiratory infection caused by severe acute respiratory syndrome coronavirus 2. Coronavirus disease 2019 leads to the rapid activation of innate immune cells, particularly in patients with severe disease. Psoriatic arthritis is a heterogeneous chronic inflammatory disease characterized by the association of psoriasis and arthritis. Similar to those with other viruses, patients with psoriatic arthritis are at a significant risk of infection with severe acute respiratory syndrome coronavirus 2. Patients with psoriatic arthritis are immunosuppressed owing to immune dysregulation during the active disease period or owing to immunosuppressive drugs administered during remission, and they are prone to infections. The severe acute respiratory syndrome coronavirus 2 is a threat to millions of people globally owing to the decline in immunity and because a significant number of people develop severe illness. In the period of coronavirus disease 2019 pandemic, we briefly present recommendations for the treatment of psoriatic arthritis. In this review, we briefly address the management options and treatment recommendations for patients with psoriatic arthritis during and after the coronavirus disease 2019 pandemic in light of recent scientific publications.

Contribution of a European-Prevalent Variant near CD83 and an East Asian-Prevalent Variant near IL17RB to Herpes Zoster Risk in Tofacitinib Treatment: Results of Genome-Wide Association Study Meta-Analyses.

ObjectiveTofacitinib is an oral JAK inhibitor for the treatment of rheumatoid arthritis (RA), psoriatic arthritis, and ulcerative colitis, and has been previously investigated for psoriasis (PsO). This meta‐analysis of genome‐wide association studies (GWAS) was performed to identify genetic factors associated with increased risk/faster onset of herpes zoster (HZ) in subjects with RA or PsO receiving tofacitinib treatment, and to determine potential mechanisms that could be attributed to the varying rates of HZ across ethnicities.MethodsIn an ethnicity/indication‐specific, trans‐ethnic, trans‐population meta‐analysis of GWAS in subjects with RA or PsO from phase II, phase III, and long‐term extension studies of tofacitinib, 8 million genetic variants were evaluated for their potential association with time to an HZ event and incidence of an HZ event (case versus control) with tofacitinib treatment, using Cox proportional hazard and logistic regression analyses, respectively.ResultsIn total, 5,246 subjects were included (3,168 with RA and 2,078 with PsO). After adjustment for age, baseline absolute lymphocyte count, genetically defined ethnicity, and concomitant methotrexate use (in RA subjects only), 4 loci were significantly associated with faster onset of HZ in European subjects (P < 5 × 10−8), including a single‐nucleotide polymorphism (SNP) near CD83 (frequency of risk allele ~2% in European subjects versus ~0.1% in East Asian subjects). In the trans‐ethnic, trans‐population meta‐analysis, the CD83 SNP remained significant. Four additional significant loci were identified in the meta‐analysis, among which a SNP near IL17RB was associated with faster onset of HZ (meta‐analysis hazard ratio 3.6 [95% confidence interval 2.40–5.44], P = 7.6 × 10−10; frequency of risk allele ~12% in East Asian subjects versus <0.2% in European subjects).ConclusionGenetic analysis of tofacitinib‐treated subjects with RA or PsO identified multiple loci associated with increased HZ risk. Prevalent variants near the immune‐relevant genes CD83 and IL17RB in European and East Asian populations, respectively, may contribute to risk of HZ in tofacitinib‐treated subjects.

Tofacitinib downregulates antiviral immune defence in keratinocytes and reduces T cell activation

BackgroundTofacitinib is a novel Janus kinase (JAK) inhibitor approved for the treatment of rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis. In clinical trials, the most common adverse events observed were nasopharyngitis, upper respiratory tract infections, and zoster. JAKs are found downstream of the type II cytokine receptor family used by a number of TH17 cell-associated cytokines for signal transduction. These cytokines lead to the secretion of antiviral and antimicrobial peptides (AMPs) by keratinocytes or synoviocytes. Blocking the JAK pathway might result in a diminished secretion of antimicrobial and antiviral peptides causing higher susceptibility to infections in patients treated with JAK inhibitors.MethodsWe treated primary human keratinocytes and synoviocytes with tofacitinib and subsequently added various cytokines and bacterial surface proteins before evaluation of the response via RT-qPCR. CD69 expression on tofacitinib-treated PBMCs was investigated via flow cytometry.ResultsWe found a markedly reduced gene expression of all tested antiviral peptides such as MX1 or ISG15 in keratinocytes and synoviocytes in the presence of tofacitinib in vitro. Additionally, we found that JAK inhibition reduced activation of T cells after stimulation with bacterial LPS or viral VZV gE.ConclusionsThe antiviral immunity is strongly inhibited in the presence of tofacitinib in vitro, while the antimicrobial immunity does not seem to be affected. In T cells, the overall activation process seems to be influenced by tofacitinib. These findings suggest that tofacitinib has an impact on antiviral immunity such as patients treated with tofacitinib often show adverse events like herpes zoster.Graphical abstract
