Biologic treatments for elderly patients with psoriasis

Comparation of time-course, dose-effect, influencing factors and adverse events of biologics in the treatment of adults with moderate to severe plaque psoriasis

Introduction

Biologics is used for treating moderate to severe plaque psoriasis (MSPP), which represent one of the foremost therapeutic advancements in disease of dermatology. Up to now, the relative efficacy and safety across approved andinvestigational biologics for MSPP is still unclear.

Methods

This study aimed to comparative effectiveness of various biological treatments for MSPP measured by PASI75, PASI90 and PASI100 (The ratio of patients whose Psoriasis Area and Severity Index score (PASI) decreased by ≥ 75%, 90% and 100% compared with baseline, respectively). In addition, random models were used together with a Bayesian method to compare direct and indirect Adverse Events (AEs) of biologics with placebo, to make probabilistic statements and predictions on their AEs. The analytic data set was made up of summarized data from 54 trials, including 27,808 patients, with treatment of 17 biologics. Three mathematic models with nonparametric placebo evaluations were established to characterize the longitudinal direction profile for the three efficacy measures as above mentioned.

Results

Our results showed significant differences among treatments. Bimekizumab, sonelokimab, and ixekizumab were found to be the most effective treatments among the biologics. The effects of covariate were further evaluated, patients' age, body weight, duration of disease and percentage of patients previously treated with a biological therapy showed impact on the efficacy. In addition, we found that ixekizumab and risankizumab displayed relatively stable as for efficacy and safety.

Discussion

Our findings provide valuable insights into the comparative effectiveness and safety of biologics for MSPP treatment. These results may aid in clinical decision-making and ultimately improve patient outcomes.

Tildrakizumab in Complex Psoriatic Patients: An Experience in Emilia-Romagna (Italy)

Background

IL-23 inhibitors are the latest class of biologic drugs approved for moderate-to-severe psoriasis.

Objectives

to investigate real-life safety and efficacy of tildrakizumab.

Methods

demographic data, medical history, psoriasis disease history, PASI, DLQI, BSA, NAPSI were recorded at weeks 0, 12, 24, 36.

Results

PASI, BSA, DLQI and NAPSI all decreased rapidly during the 36 week follow-up period. PASI score reduced from 12.28 to 4.65 by week 12, followed by a further decrease to 1.18 at week 36 Multiple logistic regression showed that smoking, BMI ≥30, ≥3 comorbidities, previous systemic traditional or biologic drugs, psoriatic arthritis nor difficult-to-treat areas influenced the reduction of PASI and NAPSI scores during treatment with tildrakizumab ( P > .05).

Conclusions

we assessed a good performance of tildrakizumab in patients with multiple comorbidities, multi-failure, elderly patients, and in subjects with psoriatic arthritis.

Efficacy and safety of biologics and small molecules for psoriasis in pediatric and geriatric populations. Part II: focus on elderly patients

INTRODUCTION

The management of moderate-to-severe forms of psoriasis is becoming a frequent concern in geriatric age due to the higher risk to develop treatment adverse events, logistic issues, vulnerability to immune-related diseases and cancer, presence of comorbidities and the risk of drug interactions. In this context, traditional systemic treatments are often contraindicated, and biologic drugs and small molecules seem to be a valuable option. However, data on their effectiveness and safety in elderly patients are scant.

AREAS COVERED

The aim of this review is to analyze the current literature in order to point out data on the efficacy and safety of biologic drugs and small molecules for the management of psoriasis in elderly patients in order to put the basis for universally shared treatment algorithm following available evidence. Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used for the literature research.

EXPERT OPINION/COMMENTARY

Our review suggests biologics and small molecules as an effective and safe option for the management of moderate-to-severe forms of psoriasis in elderly patients.

Treating psoriasis in the elderly: biologics and small molecules

INTRODUCTION

Psoriasis prevalence in the elderly is growing. It is estimated that 15% of elderly psoriasis patients suffer from moderate-to-severe disease, thus requiring systemic treatments. However, conventional systemic agents' use is limited due to contraindications and drug-interactions. Conversely, biologics and small molecules seem to be a valuable option, although the geriatric psoriasis population is frequently excluded from trials and shared guidelines are lacking.

AREAS COVERED

Relevant English literature (trials, real-life studies, case series, and reviews) regarding biologics and/or small molecules in the elderly were searched for up to January 17, 2022.

EXPERT OPINION

Treatment of moderate-to-severe psoriasis in the elderly may be challenging due to multiple comorbidities, polypharmacy, and increased risk of infections and cancers. However, new targeted therapies offer the possibility to perform a tailored-tail management, considering comorbidities, drug-interactions, and frailties which characterize this class of patients. Several real-world data support biologics and small molecules' efficacy and safety in the elderly with mainly no significant difference as compared to young adults. Elderly psoriasis patients' expectations are as high as those of their younger counterparts. Hence, they deserve the best therapeutic options according to their peculiarities for a long-term psoriasis remission and an improved quality of life.

Therapy of PsO in Special Subsets of Patients

Psoriasis is a chronic, inflammatory skin disease that may occur at any age, with a bimodal peak of incidence around the age of 16-20 years of age (early onset) and 57-60 years (late-onset). It is estimated that roughly 70% of patients develop the disease before the age of 40, which coincides with the reproductive years. Moreover, psoriasis is a chronic disease, meaning that, with increased life-duration expectancy, the number of patients affected with psoriasis aged over 65 years is going to increase and represent a big therapeutic challenge. Actually, no specific drug recommendation is available, based only on the age of the patients, while therapeutic prescription should take into account that elderly patients have more comorbidities than younger patients, with polypharmacy and an increased risk of drug interactions. Women with psoriasis are more likely to report a worse influence of the disease on their quality of life, and they are more susceptible to the development of depression. Furthermore, pregnancy and lactation represent a major contraindication to several systemic agents, and only a few studies exist providing the safety of certain drugs during these periods of life of a woman, such as certolizumab pegol. In this paper, we discuss systemic therapeutic strategies, including conventional and biological therapies, in a special subset of patients affected with moderate-to-severe psoriasis focusing on elderly patients and on female patients in fertile age, pregnancy, and lactation.

[Translated article] Practical Update of the Guidelines Published by the Psoriasis Group of the Spanish Academy of Dermatology and Venereology (GPs) on the Treatment of Psoriasis With Biologic Agents: Part 2-Management of Special Populations, Patients With Comorbid Conditions, and Risk

BACKGROUND AND OBJECTIVES

Since its inception, the Psoriasis Group (GPs) of the Spanish Academy of Dermatology and Venereology (AEDV) has worked to continuously update recommendations for the treatment of psoriasis based on the best available evidence and incorporating proposals arising from and aimed at clinical practice. An updated GPs consensus document on the treatment of moderate to severe psoriasis was needed because of changes in the treatment paradigm and the approval in recent years of a large number of new biologic agents.

METHODOLOGY

The consensus document was developed using the nominal group technique complemented by a scoping review. First, a designated coordinator selected a group of GPs members for the panel based on their experience and knowledge of psoriasis. The coordinator defined the objectives and key points for the document and, with the help of a documentalist, conducted a scoping review of articles in Medline, Embase, and the Cochrane Library up to January 2021. The review included systematic reviews and meta-analyses as well as clinical trials not included in those studies and high-quality real-world studies. National and international clinical practice guidelines and consensus documents on the management of moderate to severe psoriasis were also reviewed. The coordinator then drew up a set of proposed recommendations, which were discussed and modified in a nominal group meeting. After several review processes, including external review by other GPs members, the final document was drafted.

RESULTS

The present guidelines include updated recommendations on assessing the severity of psoriasis and criteria for the indication of systemic treatment. They also include general principles for the treatment of patients with moderate to severe psoriasis and define treatment goals for these patients as well as criteria for the indication and selection of initial and subsequent therapies Practical issues, such as treatment failure and maintenance of response, are also addressed.

Risk of tuberculosis infection and serial changes in interferon-gamma release assays in elderly patients with psoriasis receiving biologic therapy

Elderly patients constitute a significant proportion of patients with psoriasis. Nonetheless, treatment for older patients is more challenging than that for younger ones. Biologic agents are preferable to other systemic drugs for elderly patients with moderate-to-severe psoriasis owing to their high efficacy and favorable tolerability. However, there are limited data on tuberculosis infection risk in elderly patients with psoriasis receiving biologic therapy. This study aimed to evaluate the risk of active tuberculosis and latent tuberculosis infection, assess the serial interferon-gamma release assay results, and evaluate treatment compliance and adverse effects of latent tuberculosis infection treatment in elderly patients with psoriasis on biologic therapy. In this single-center retrospective study, medical charts of elderly patients (age ≥ 65 years) with psoriasis who were treated with a biologic agent (guselkumab, adalimumab, secukinumab, or ustekinumab) between January 2015 and December 2020 were reviewed. We analyzed the results of chest X-rays and those of whole-blood interferon-gamma release assays performed for latent tuberculosis infection screening at baseline (IGRA0) and subsequently at follow-up after initiating biologic therapy (IGRA1). In total, 90 patients underwent IGRA0; 46 (51.11%) of them had latent tuberculosis infection before starting biologic therapy. Overall, four and two patients experienced seroconversion and active tuberculosis during biologic therapy, respectively. The interferon-gamma release assay reversion rate was 29.1%, and the interferon-gamma level significantly decreased in all patients after latent tuberculosis infection treatment (p = 0.004). Latent tuberculosis infection treatment was well tolerated in elderly patients (completion rate, 100%). The risk of latent tuberculosis infection in elderly patients with psoriasis on biologic therapy was comparable to that previously reported for all age groups. However, the active tuberculosis rate was relatively higher.

Use of Biological Treatments in Elderly Patients with Skin Psoriasis in the Real World

Biological drugs have prompted a revolution in the treatment of patients with psoriasis because of their favourable efficacy/risk profile. The aims of our study are to determine whether there is any difference in the pattern of use of biological treatments for older (65+ years) and younger patients diagnosed with plaque psoriasis by the Dermatology Service of the Hospital Universitario de Asturias (HUCA), to understand the survival of these drugs, and to identify the factors that predict the discontinuation of treatments. We report a retrospective observational hospital-based study of 300 patients registered at HUCA’s Dermatology Service who were receiving one of the following biological treatments for psoriasis on 30 November 2020: adalimumab, ustekinumab, secukinumab, or ixekizumab. The age groups were compared using Student’s t-test for quantitative variables and the chi-squared test for qualitative variables. We used the Kaplan–Meier estimator to estimate the survival function and the log-rank test to measure differences. No statistically significant differences in the frequency of use were noted between the younger and older groups, for any of the drugs studied. Survival on a drug regime, globally and individually, was similar in the two age groups. Factors predicting lower overall survival were being female, obesity, and having undergone previous biological treatment. The first three factors were influential in the under-65-year-old group, while arthritis was a significant factor for the older group.

Safety of Systemic Medications Among Older Adults With Psoriasis and Atopic Dermatitis: A Systematic Review of Observational Studies

BACKGROUND

Psoriasis and atopic dermatitis are common among older adults (≥65 years old), but clinical trials often exclude that population.

OBJECTIVE

To synthesize evidence from observational studies on the safety of systemic therapies (conventional or biologic) for psoriasis and atopic dermatitis among older adults in a systematic review.

METHODS

We searched MEDLINE and EMBASE (inception to October 31, 2019) and included observational studies reporting adverse events among older people treated with systemic therapy for psoriasis or atopic dermatitis. Outcomes were death, hospitalization, emergency department visits, infections, major cardiovascular events, renal toxicity, hepatotoxicity, and cytopenias. We assessed study quality using the Newcastle-Ottawa Scale.

RESULTS

We included 22 studies on treatment for psoriasis and 2 for atopic dermatitis. Most studies were small and non-comparative and 20 of 24 were low quality. Studies comparing safety between medications or medication classes or between older and younger adults did not show apparent differences but had wide confidence intervals around relative effect estimates. Heterogeneity of study design and reporting precluded quantitative synthesis.

CONCLUSIONS

There is scant evidence on the safety of conventional systemic and biologic medications for older adults with psoriasis or atopic dermatitis; older adults and their clinicians should be aware of this evidence gap.

Psoriasis in the geriatric population: A retrospective study in Asians

There is a paucity of data focusing on geriatric psoriatic patients. The clinical features were different among those with early-onset psoriasis and elderly-onset psoriasis among the geriatric population. From 2014 to 2018, a total of 290 geriatric psoriatic patients were retrospectively enrolled in our study. They were subclassified into two groups, early-onset (aged <60 years, n = 154) and elderly-onset (aged ≥60 years, n = 136). The characteristics and treatment course of these two groups were reviewed. Psoriasis of the elderly-onset group was generally milder than the early-onset groups (P < 0.05). Less nail involvement and arthritis were noted among the elderly-onset group (P < 0.05). There were four cases of erythrodermic psoriasis in the early-onset group and three cases of palmoplantar psoriasis in the elderly-onset group. Oral medication and biologics for treatment of psoriasis appeared to be safe among the geriatric psoriatic patients. Elderly-onset psoriasis has features which are distinct from early-onset psoriasis and may be a particular subtype, which needs further evaluation.

Adalimumab in Elderly Patients with Non-Infectious Uveitis. Safety and Efficacy

PURPOSE

To assess the efficacy and safety of adalimumab in elderly patients with noninfectious uveitis (NIU).

METHODS

An observational, retrospective, multicenter study was done. Changes in best-corrected visual acuity (BCVA), inflammatory activity parameters, central retinal thickness (CRT), and the occurrence of adverse events (AE) developed during follow-up were recorded.

RESULTS

A total of 82 eyes from 41 patients 60 years of age and older with noninfectious uveitis treated with adalimumab were included. A significant improvement in BCVA (71.5 to 75.4 letters, p = .001) and in CRT (311.1 μm to 265 μm, p = .001) was observed. Moreover, a significant decrease from baseline in the rate of patients with anterior chamber cell (ACC) >0+ (34.6% to 5.7%, p = <0.001) or vitreous haze>0+ (21.3% to 4.3%, p = .002) was determined. AEs were observed in 11 patients (26.8%).

CONCLUSION

Adalimumab can be safe and efficacious for the treatment of NIU in patients 60 years of age and older.

Safety concerns with current treatments for psoriasis in the elderly

Introduction: The approach to manage psoriasis in the elderly (ages ≥65 years) patients can be challenging. They often suffer from multiple comorbidities and polypharmacy with possible adverse effects and undergo a progressive functional impairment of the immune system that increases susceptibility to infections as well as to auto-reactivity. Despite the increasing aging of the general population and although several therapies are currently available for psoriasis treatment, data regarding their use and tolerability in the elderly are quite limited.Areas covered: This review focuses on topical and systemic therapies that have been investigated in elderly patients in order to provide their safety profile in this population.Expert opinion: Conventional systemic therapies in elderly patients should be carefully dispensed and the correct dosage individually determined, taking into account the metabolism changes, organ impairment, comorbidities, concomitant medications, and contraindications. Apremilast, due to its satisfactory safety profile and low risk of drug interactions, results as an appropriate treatment option for elderly patients. Biologics (TNF-α, IL-12/23, IL-17, and IL-23 inhibitors) come out as safe and long-term options for the management of these patients resulting not associated with a higher risk of adverse events.

Biologic Treatment in Elderly Patients With Psoriasis: A Systematic Review

With our aging population, an increasing number of psoriasis patients are classified as elderly. However, psoriasis treatment in older adults can be challenging, given an increased number of comorbid conditions and immunosenescence. Biologic agents present a solution to this treatment dilemma because of their high efficacy and favorable tolerability. The objective of this systematic review was to summarize the findings of clinical trial and real-world studies exploring the safety and efficacy of biologic agents in elderly patients with moderate-to-severe psoriasis. We searched MEDLINE, Embase, the Cochrane Library, and clinical trial databases. Studies analyzing biologics for psoriasis were included if elderly patients were the main population of interest or were a separate subgroup in their analysis. Eighteen articles met inclusion criteria after screening. Across all biologic classes, efficacy for biologics between nonelderly adult patient and elderly patients was similar. Adverse events (AEs) and infections occured at a similar frequency between both groups. However, serious AEs were more common in the elderly. The available literature on the safety and efficacy of biologic agents in elderly patients supports the use of these agents in this population. However, serious AEs and discontinuation due to AEs were more common in older patients. As elderly patients have a higher burden of comorbid conditions and an increased baseline vulnerability for AE, physicians should continue to be prudent in screening before initiating biologics and monitor patients more closely as AEs tend to be more severe.

Safety of Biologic Therapy in Older Patients With Immune-Mediated Diseases: A Systematic Review and Meta-analysis

BACKGROUND & AIMS

Management of immune-mediated inflammatory diseases often requires lifelong immunosuppression. Increasing numbers of older patients have inflammatory diseases and are particularly vulnerable to risks of immune suppressive therapies-particularly infections and malignancies.

METHODS

We systematically searched PubMed/Medline and Embase to identify eligible studies that examined the safety of biologic therapies in older patients with immune-mediated inflammatory diseases (inflammatory bowel disease, rheumatoid arthritis, psoriasis). Included studies provided information on patients who began receiving therapy with a biologic agent when they were older than 60 years and a control population (either younger users of biologics or older patients who did not use biologics). Information of on overall pooled rates of infections, malignancy, and mortality were extracted. A DerSimonian and Laird random effects model was used to calculate pooled odds ratios (ORs) and 95% CIs.

RESULTS

Our meta-analysis included 14 unique studies that comprised 4719 older users of biologics, 13,305 younger users of biologics, and 3961 older patients who did not use biologics. The pooled prevalence of infections in older and younger users of biologics was 13% and 6% respectively, yielding a pooled random effects odds ratio of 2.28 (95% CI, 1.57-3.31). Older age was associated with a significant increase in risk of malignancy (OR, 3.07; 95% CI, 1.98-4.62) compared to younger age. Older users of biologics had a 3-fold increase in risk of infection compared to patients who did not use biologics (OR, 3.60; 95% CI, 1.62-8.01), but there were no significant differences in odds of malignancy (0.54, 95% CI, 0.28-1.05) or death (OR, 1.52; 95% CI, 0.44-5.28) compared to older patients who did not use biologics.

CONCLUSION

In a systematic review and meta-analysis of studies on the safety of biologic therapies in older patients with inflammatory diseases, we found that older users of biologic agents have an increased risk of infections compared with younger users or older patients who do not use biologics. Large, prospective cohort studies are needed to examine safety of biologic therapy in older patients with immune-mediated diseases.

Sustainability and switching of biologics for psoriasis and psoriatic arthritis at Fukuoka University Psoriasis Registry

Biologics are efficacious for treating psoriasis vulgaris (PsV) and psoriatic arthritis (PsA), but sometimes must be terminated or changed for various reasons including ineffectiveness or adverse events. To find the optimal choice of biologics for treating psoriasis, we analyzed the real-world data on drug survival and the reason for terminating or switching biologics. Medical records from patients with PsV or PsA, who visited the Department of Dermatology, Fukuoka University Hospital from 2010 to 2017, were analyzed. Two hundred and eleven patients received biologics, and 147 patients (69.7%) were treated with only one biologic, while 64 patients (30.3%) were switched to different products. Frequently used biologics in PsV were ustekinumab (UST), infliximab and adalimumab when calculated by patient-year. Tumor necrosis factor inhibitor (TNFi) use decreased while UST and interleukin (IL)-17 inhibitors increased in newly introduced patients. UST showed the highest survival rate as a first-line drug, but the advantage was lost in the second reagent's group. The major reasons for terminating/switching biologics were as follows: primary ineffectiveness (26.4%), secondary loss of efficacy (36.5%), patient's preference, including referral to nearby hospital, or stopped visiting (22.6%), side-effects (7.7%), comorbidities (3.4%) and economic burden (2.4%). In PsA patients, TNFi are more frequently employed than in PsV patients, although switching to UST or IL-17 inhibitors showed an increasing trend. Biologic reagents were changed mostly because of primary or secondary loss of efficacy, which affected drug survival. Further research is needed to find the optimal choice of biologics with larger samples at multiple facilities.

Differential efficacy of biologic treatments targeting the TNF-α/IL-23/IL-17 axis in psoriasis and psoriatic arthritis

Psoriasis and psoriatic arthritis cause significant physical and psychological burdens for afflicted individuals. An accelerated TNF-α/IL-23/IL-17 axis is their major pathomechanism; therefore, anti-TNF-α/IL-23/IL-17 biologics are very effective for the treatment of skin and joint lesions in psoriasis and psoriatic arthritis. Given that the IL-17 signature is more upregulated in the skin than in synovium in psoriatic arthritis, anti-IL-23/IL-17 agents seem to be superior to anti-TNF-α remedies in the treatment of skin lesions. In this review, we focus on the differential efficacy of anti-TNF-α/IL-23/IL-17 biologics in psoriasis and psoriatic arthritis.

Elderly psoriatic patients under biological therapies: an Italian experience

BACKGROUND

The number of elderly patients with psoriasis is steadily increasing in the Western world; nevertheless, they are frequently excluded from biological clinical trials and described as a high-risk group for adverse events. Thus, there is lack of information concerning safety and effectiveness of available treatments for psoriasis in the elderly, particularly about new biological systemic drugs.

OBJECTIVE

Our aim was to describe our experience with all biological therapies currently used in the elderly (>65 years) psoriatic patients.

METHODS

A retrospective multicentric review of clinical records of all psoriatic patient aged 65 years or older actually receiving biological drugs (etanercept, adalimumab, infliximab, golimumab, certolizumab pegol, ustekinumab or secukinumab) was undertaken.

RESULTS

Our study population included 266 elderly psoriatic patients actually receiving any biological therapy (adalimumab 31.2%, ustekinumab 28.9%, etanercept 20.3%, secukinumab 15%, infliximab 3%, golimumab 1% and certolizumab pegol 0.6%). The PASI score at the baseline (week 0) ranged from 4 to 54; mean ± SD, 16.5 ± 7.1, which changed after biological administration to 3.7 ± 8 at week 16, 1.6 ± 2.1 at week 28 and 1.2 ± 2.1 at week 52. Among 266 elderly psoriatic patients, 25 adverse events were reported during the observation period. The most frequent events were infections with 12 (48%) reports, followed by malignancies with four (16%) reports.

CONCLUSIONS

To date, our study represents the widest experience on the use of biological drugs in elderly psoriatic patients. We found that all biologics for psoriasis showed a great efficacy also in elderly people, and the rate and the type of adverse effects were similar to the younger patients. In conclusion, the age alone should not limit our therapeutic options. Further observational study using multiple data sources is needed to evaluate long-term effectiveness and safety for elderly psoriatic patients.

Autoimmunity and autoimmune co-morbidities in psoriasis

Psoriasis is characterized by widespread scaly erythematous plaques that cause significant physical and psychological burdens for the affected individuals. Accelerated inflammation driven by the tumour necrosis factor-α/interleukin-23/interleukin-17 axis is now known to be the major mechanism in the development of psoriasis. In addition, psoriasis has an autoimmune nature that manifests as autoreactive T cells and is co-morbid with other autoimmune diseases, such as autoimmune bullous diseases, vitiligo, alopecia and thyroiditis. In this article, we review the recent topics on autoimmunity and autoimmune co-morbidities in psoriasis.
