Efficacy and safety of ustekinumab in a group of 22 elderly patients with psoriasis over a 2-year period

Clinical Pharmacokinetic and Pharmacodynamic Considerations in the Treatment of Moderate-to-Severe Psoriasis

Psoriasis is a common inflammatory immune disorder due to chronic activation of the adaptive and innate immune responses. Therapies for psoriasis target reducing inflammatory cytokines such as tumor necrosis factor-alpha, interleukin-17, and interleukin-22. Patients with inflammatory disorders have reduced metabolism by cytochrome P450 enzymes in the liver. The pharmacokinetic and pharmacodynamic changes due to psoriasis also have an impact on reaching therapeutic concentrations of the drug. Pharmacokinetic and pharmacodynamic data help determine the safety and clinical considerations necessary when utilizing drugs for plaque psoriasis. A literature search was performed on PubMed and Ovid MEDLINE for the pharmacokinetic and pharmacodynamic data of oral therapies and biologics utilized for moderate-to-severe plaque psoriasis. The findings from the literature search were organized into two sections: oral therapies and biologics. The pharmacokinetic and pharmacodynamic parameters in healthy patients, patients with psoriasis, and special populations are discussed in each section. The oral therapies described in this review include methotrexate, cyclosporine, apremilast, tofacitinib, and deucravacitinib. Biologics include tumor necrosis factor-alpha inhibitors, interleukin-17 inhibitors, ustekinumab, and interleukin-23 inhibitors. Clinical considerations for these therapies include drug toxicities, dosing frequency, and anti-drug antibodies. Methotrexate and cyclosporine have a risk for hepatoxicity and renal impairment, respectively. Moreover, drugs metabolized via cytochrome P450, including tofacitinib and apremilast have decreased clearance in patients with psoriasis, requiring dose adjustments. Patients treated with therapies such as adalimumab can develop anti-drug antibodies that reduce the long-term efficacy of the drug. Additionally, overweight patients benefit from more frequent dosing to achieve better psoriasis clearance.

Systemic treatment of psoriasis in special population

Psoriasis is a common skin disorder affecting approximately 1% of the general population. The treatment of psoriasis depends on the body surface area involvement, quality of life impairment and associated co-morbidities. Special population comprising of pregnant women, lactating mothers, elderly individuals and children, is more vulnerable. They are not included in drug trials; rendering the data for use of systemic treatment scant and is mainly based on anecdotal evidence. In this narrative review, we discuss systemic treatment options in this special population. Though couples planning a family are not considered a special population, they form a subset that require special therapeutic consideration and have also been included in this review.

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.

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.

Safety and effectiveness of ustekinumab in elderly Crohn's disease patients

OBJECTIVE

Anti-tumour necrosis factor (TNF) agents are associated with increased infection risk among elderly IBD patients, but little is known about non anti-TNF biologics in this cohort. We examined the safety and effectiveness of ustekinumab in elderly Crohn's patients.

METHODS

This retrospective multi-centre cohort study included Crohn's patients ≥60-years old who commenced ustekinumab. We recorded Harvey-Bradshaw index (HBI), concomitant steroid therapy, treatment persistence and new infections or malignancies. Primary outcome was serious infections requiring hospitalisation.

RESULTS

Seventy patients were included, with median age of 68 years. 43 (61.4%) had prior anti-TNF exposure, and 15 (21.4%) vedolizumab. Median treatment duration was 12 months, totalling 84 patient-years. Nine serious infections were reported, incidence 106.7/1000 patient-years. Systemic steroids were associated with increased risk of serious infections [odds ratio (OR) 7.83, 95% confidence interval (CI): 1.44-44.32, P = 0.02]. There were 27 "non-serious" infections; 321.4/1000 patient-years. Charlson co-morbidity index (OR 1.49, 95% CI: 1.05-2.12, P = 0.03) and steroid exposure (OR 44.10, 95% CI: 1.75-1112.10, P = 0.02) increased non-serious infection risk (P < 0.05). Mean HBI improved from 8.13 to 4.64 at 6 months and 4.10 at last follow up (P < 0.0001). 12-month treatment persistence was 55.7% (N = 39); 34 (48.6%) were steroid-free.

CONCLUSION

Ustekinumab was safe and effective in a cohort of elderly Crohn's disease patients. Infections were mostly mild, not resulting in therapy discontinuation. Serious infection risk was comparable to previously reported rates with anti-TNF agents. Steroid exposure was associated with an increased serious infection risk.

Drug Survival, Safety, and Effectiveness of Biologics in Older Patients with Psoriasis: A Comparison with Younger Patients-A BioCAPTURE Registry Study

BACKGROUND

Psoriasis is a common inflammatory disease in any age group, but also in older patients (≥ 65 years of age). Since older patients are often excluded from clinical trials, limited data specifically on this growing population are available, e.g. regarding the safety and performance of biological treatment.

AIMS

We aimed to give insight into this specific population by comparing the drug survival and safety of biologics in older patients with that in younger patients.

METHODS

In this real-world observational study, data from 3 academic and 15 non-academic centers in The Netherlands were extracted from the prospective BioCAPTURE registry. Biologics included in this study were tumor necrosis factor (TNF)-α, interleukin (IL)-17, IL-12/23, and IL-23 inhibitors. Patients were divided into two age groups: ≥ 65 years and < 65 years. The Charlson Comorbidity Index (CCI) was used to measure comorbid disease status, and all adverse events (AEs) that led to treatment discontinuation were classified according to the Medical Dictionary for Regulatory Activities (MedDRA) classification. All AEs that led to treatment discontinuation were studied to check whether they could be classified as serious AEs (SAEs). Kaplan-Meier survival curves for overall 5-year drug survival and split according to reasons of discontinuation (ineffectiveness or AEs) were constructed. Cox regression models were used to correct for possible confounders and to investigate associations with drug survival in both age groups separately. Psoriasis Area and Severity Index (PASI) scores during the first 2 years of treatment and at the time of treatment discontinuation were assessed and compared between age groups.

RESULTS

A total of 890 patients were included, of whom 102 (11.4%) were aged ≥ 65 years. Body mass index, sex, and distribution of biologic classes (e.g. TNFα, IL12/23) were not significantly different between the two age groups. A significantly higher CCI score was found in older patients, indicative of more comorbidity (p < 0.001). The 5-year ineffectiveness-related drug survival was lower for older patients (44.5% vs. 60.5%; p = 0.006), and the 5-year overall (≥ 65 years: 32.4% vs. < 65 years: 42.1%; p = 0.144) and AE-related (≥ 65 years: 82.1% vs. < 65 years: 79.5%; p = 0.913) drug survival was comparable between age groups. Of all AEs (n = 155) that led to discontinuation, 16 (10.3%) were reported as SAEs but these only occurred in younger patients. After correcting for confounders, the same trends were observed in the drug survival outcomes. Linear regression analyses on PASI scores showed no statistical differences at 6, 12, 18, and 24 months of treatment between age groups.

CONCLUSIONS

This study in a substantial, well-defined, prospective cohort provides further support that the use of biologics in older patients seems well-tolerated and effective. Biologic discontinuation due to AEs did not occur more frequently in older patients. Older patients discontinued biologic treatment more often due to ineffectiveness, although no clear difference in PASI scores was observed. More real-world studies on physician- and patient-related factors in older patients are warranted.

[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.

How to Choose the Biologic Therapy in a Bio-Naïve Patient with Inflammatory Bowel Disease

The availability of biologic therapies in inflammatory bowel disease (IBD) is increasing significantly. This represents more options to treat patients, but also more difficulties in choosing the therapies, especially in the context of bio-naïve patients. Most evidence of safety and efficacy came from clinical trials comparing biologics with placebo, with a lack of head-to-head studies. Network meta-analysis of biologics and real-world studies have been developed to solve this problem. Despite the results of these studies, there are also other important factors to consider before choosing the biologic, such as patient preferences, comorbidities, genetics, and inflammatory markers. Given that resources are limited, another important aspect is the cost of biologic therapy, since biosimilars are widely available and have been demonstrated to be effective with a significant decrease in costs. In this review, we summarize the evidence comparing biologic therapy in both Crohn´s disease (CD) and ulcerative colitis (UC) in different clinical situations. We also briefly synthesize the evidence related to predictors of biologic response, as well as the biologic use in extraintestinal manifestations and the importance of the drug-related costs.

Anti-interleukin-23 for psoriasis in elderly patients: guselkumab, risankizumab and tildrakizumab in real-world practice

Background

Elderly patients (aged ≥ 65 years) represent an increasing proportion of patients with psoriasis and 15% of these have moderate to severe disease. Biologics are being used frequently in this group of patients even though safety and efficacy data are limited. In addition, owing to anti‐interleukin (IL)‐23 therapies being a relatively recent option, no data have been reported about their use in elderly patients with psoriasis.

Aim

To evaluate and compare the safety and efficacy of guselkumab, risankizumab and tildrakizumab in real‐world practice in elderly patients.

Methods

This was a single‐centre retrospective study that enrolled patients aged ≥ 65 years with moderate to severe plaque psoriasis, treated with guselkumab, risankizumab or tildrakizumab. The length of the study for each group depended on the drug (44 weeks for risankisumab, 40 weeks for guselkumab and 28 weeks for tildrakizumab, owing to its more recent availability in Italy).

Results

In total, 34 patients were enrolled (n = 20 on guselkumab; n = 8 on risankizumab; n = 6 on tildrakizumab). At Week 4, 29.4% reached 90% improvement in Psoriasis Area and Severity Index (PASI90) and 8.8% reached 100% improvement in PASI (PASI100); at Week 28, PASI90 and PASI100 was reached by 58.8% and 29.4%, respectively. At the final follow‐up (Week 40 or 44, depending on drug), data were available only for the risankizumab (Week 40) and guselkumab (Week 44) and groups, and showed that 71.4% of patients had reached PASI90 and 53.5% had reached PASI100. Four patients (11.7%) discontinued treatment. No significant differences were found between the three groups. The limitations of the study included its retrospective nature of the study, small sample size, and different numbers of patients and follow‐up duration for the different groups (highest for guselkumab, lowest for tildrakizumab).

Conclusion

The three anti‐IL‐23 therapies assessed are promising, safe and effective options in elderly patients, and there was no significant difference between them. However, more data are needed to confirm our results and to understand their role in the management of this group of patients.

The elderly IBD patient in the modern era: changing paradigms in risk stratification and therapeutic management

The incidence and prevalence of inflammatory bowel disease (IBD) is rising in the elderly population. Compared with patients with onset during their younger years, patients with elderly onset IBD have a distinct clinical presentation, disease phenotype, and natural history. Genetics contribute less to pathogenesis of disease, whereas biological changes associated with aging including immunosenescence, dysbiosis, and frailty have a greater impact on disease outcomes. With the advent of an increasingly wider array of biologic and small-molecule therapeutic options, data regarding efficacy and safety of these agents in elderly IBD patients specifically are paramount, given the unique characteristics of this population.

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.

Safety and efficacy of interleukin inhibitors in elderly patients with rheumatoid arthritis, psoriasis, and psoriatic arthritis

Elderly patients with rheumatoid arthritis, psoriasis and psoriatic arthritis encompass those with elderly-onset disease, over 60 years of age, but also those with earlier disease onset who entered old age. Considering the age-related changes of the immune system, possible frailty, susceptibility to infection and concomitant comorbidity that implies multiple medicines, the treatment of these diseases in elderly patients can be challenging. Interleukin inhibitors have been shown to be an efficient and safe treatment for these diseases. However, elderly patients with these diseases were often included in the pivotal clinical trials for interleukin inhibitors in numbers insufficient to determine whether they responded differently from younger subjects. The aim of this paper was to review the findings on the efficacy and safety of interleukin inhibitor treatment in elderly patients with rheumatoid arthritis, psoriasis, and psoriatic arthritis. The findings suggest that, for all the interleukin inhibitors reviewed herein, used in elderly patients with rheumatoid arthritis, or with psoriasis and psoriatic arthritis, the efficacy was comparable to younger patients. Furthermore, the incidence of reported adverse events was similar in these two age groups. Severe adverse events, which were related to sarilumab treatment for rheumatoid arthritis and secukinumab treatment for psoriasis, were higher in elderly patients. The reviewed findings suggest that the interleukin inhibitors approved and currently in use in clinical practice for the treatment of rheumatoid arthritis, psoriasis, and psoriatic arthritis can be considered a safe and efficient option for these diseases in elderly patients.

Controversies in Vitamin D: A Statement From the Third International Conference

The Third International Conference on Controversies in Vitamin D was held in Gubbio, Italy, September 10–13, 2019. The conference was held as a follow‐up to previous meetings held in 2017 and 2018 to address topics of controversy in vitamin D research. The specific topics were selected by the steering committee of the conference and based upon areas that remain controversial from the preceding conferences. Other topics were selected anew that reflect specific topics that have surfaced since the last international conference. Consensus was achieved after formal presentations and open discussions among experts. As will be detailed in this article, consensus was achieved with regard to the following: the importance and prevalence of nutritional rickets, amounts of vitamin D that are typically generated by sun exposure, worldwide prevalence of vitamin D deficiency, the importance of circulating concentrations of 25OHD as the best index of vitamin D stores, definitions and thresholds of vitamin D deficiency, and efficacy of vitamin D analogues in the treatment of psoriasis. Areas of uncertainly and controversy include the following: daily doses of vitamin D needed to maintain a normal level of 25OHD in the general population, recommendations for supplementation in patients with metabolic bone diseases, cutaneous production of vitamin D by UVB exposure, hepatic regulation of 25OHD metabolites, definition of vitamin D excess, vitamin D deficiency in acute illness, vitamin D requirements during reproduction, potential for a broad spectrum of cellular and organ activities under the influence of the vitamin D receptor, and potential links between vitamin D and major human diseases. With specific regard to the latter area, the proceedings of the conference led to recommendations for areas in need of further investigation through appropriately designed intervention trials. © 2020 The Authors.

Optimizing the Treatment of Moderate-to-Severe Psoriasis in Older Adults

Psoriasis is a lifelong disease and its prevalence in older adults continues to increase as the population ages. Therefore, it is important for physicians to understand the management of the disease in this population. While the management of psoriasis in older adults is similar to the management of patients below the age of 65 years, there are special considerations when treating older patients. Older patients may have more comorbidities, more immunosuppression, and are often taking additional medications that can interact with those being used to treat psoriasis. Safer and more effective treatment options for psoriasis have been introduced in recent years, particularly injectable biological agents. Unfortunately, older patients with psoriasis are oftentimes underrepresented in the clinical trials for these new medications. Subsequent studies have focused on the safety and efficacy of these medications in older adults. The results of these studies demonstrate that biologic agents are well tolerated in older patients and are more effective in treating psoriasis than conventional systemic therapies. In addition, new small-molecule agents such as apremilast also offer an effective and safe treatment option for older patients with psoriasis. The results of these studies can help guide physicians with incorporating these newer medications into the treatment regimen of older psoriasis patients. Despite the proven safety and efficacy of biologic agents, their frequency of use in elderly patients is still almost half of that in non-elderly patients.

Patients' demographic and socioeconomic characteristics influence the therapeutic decision-making process in psoriasis

Background

Knowledge regarding differences in care for psoriatic patients is limited. The aim of this study was to investigate factors influencing prescription of systemic treatments for patients with psoriasis with a special focus on socioeconomic factors.

Methods and findings

This was a non-interventional, cross-sectional study, conducted in 18 Italian University and/or hospital centers with psoriasis-specialized units. Questionnaires evaluating demographic and socioeconomic characteristics were administered to participants. Overall, 1880 consecutive patients affected by mild-to-severe psoriasis were recruited. Univariate and multivariable logistic regression analyses of systemic therapy prescription, with a special focus on biologics, accounting for the above mentioned characteristics were performed. Our analysis showed that all analyzed patients’ characteristics were significantly associated with biological therapy compared to non-biological systemic one. Particularly, women were less likely to receive biologics than men (OR = 0.66; 95% CI, 0.57–0.77). Elderly patients (≥65 years) and subjects with a BMI ≥30 had lower odds to receive biologics respect to adults (≥35–64 years) (OR = 0.33; 95% CI, 0.25–0.40), and subjects with BMI≥25<30 (OR = 0.64; 95% CI, 0.53–0.77), respectively. Northern and Southern patients were both less likely to receive biologics than Central patients (OR = 0.75; 95% CI, 0.63–0.89, and OR = 0.56; 95% CI,0.47–0.68, respectively). Lower economic profile and never reading books were both associated with decreased odds of receiving biological therapy.

Conclusions

This study shows that sex, age, comorbidities, and socioeconomic characteristics influence the prescription of systemic treatments in psoriasis, highlighting that there are still unmet needs influencing the therapeutic decision-making process that have to be addressed.

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.

Treatment of Medicare Patients with Moderate-to-Severe Psoriasis who Cannot Afford Biologics or Apremilast

Elderly patients are a group with a high frequency of psoriasis. Their disease burden has negative impacts on their quality of life. While there is a clear need to treat these patients, there are challenges in doing so. This work seeks to define the challenges that exist in treating elderly Medicare patients, as well as to provide treatment suggestions for providers to follow if they encounter one or more of these challenges. Providers face the following challenges when creating treatment plants for elderly patients with psoriasis: difficulty in obtaining drug coverage through Medicare, increased medical comorbidities, and polypharmacy. Providers aim for regimens that are affordable, safe, and efficacious, but it is not always clear how to achieve this combination, especially in elderly Medicare patients. This work is relevant in that it aims to explain the logistical roadblocks posed by Medicare coverage and provide solutions for commonly encountered issues in the treatment of a disabling and common disease in a high-risk population. Specifically, alternative treatment options to biologics and small-molecule inhibitors are discussed and include topical therapies, phototherapy, methotrexate, acitretin, and cyclosporine and for psoriatic arthritis include corticosteroids and leflunomide. The specific risks and benefits of these therapies in the elderly population are provided, allowing providers to make patient-specific decisions about optimal regimens.

Management of inflammatory rheumatic conditions in the elderly

The number of elderly people with chronic inflammatory rheumatic diseases is increasing. This heterogeneous and comorbid population is at particular risk of cardiovascular, neoplastic, infectious and iatrogenic complications. The development of biotherapies has paved the way for innovative therapeutic strategies, which are associated with toxicities. In this review, we have focused on the scientific and therapeutic changes impacting the management of elderly patients affected by RA, SpA or PsA. A multidimensional health assessment resulting in an integrated therapeutic strategy was identified as a major research direction for improving the management of elderly patients.

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.

How to manage IBD in the 'elderly'

As the incidence of inflammatory bowel disease (IBD) rises and the global population ages, the number of older people living with these conditions will inevitably increase. The challenges posed by comorbid conditions, polypharmacy, the unintended consequences of long-term treatment and the real but often underestimated mismatch between chronological and biological ages underpin management. Significantly, there may be differences in disease characteristics, presentation and management of an older patient with IBD, together with other unique challenges. Importantly, clinical trials often exclude older patients, so treatment decisions are frequently pragmatic, extrapolated from a number of sources of evidence and perhaps primarily dictated by concerns around adverse effects. This review aimed to discuss the epidemiology, clinical features and considerations with management in older patients with IBD.

Elderly patients with inflammatory bowel disease: Updated review of the therapeutic landscape

High-quality data remains scarce in terms of optimal management strategies in the elderly inflammatory bowel disease (IBD) population. Indeed, available trials have been mostly retrospective, of small sample size, likely owing to under-representation of such a population in the major randomized controlled trials. However, in the last five years, there has been a steady increase in the number of published trials, helping clarify the estimated benefits and toxicity of the existing IBD armamentarium. In the Everhov trial, prescription strategies were recorded over an average follow-up of 4.2 years. A minority of elderly IBD patients (1%-3%) were treated with biologics within the five years following diagnosis, whilst almost a quarter of these patients were receiving corticosteroid therapy at year five of follow-up, despite its multiple toxicities. The low use of biologic agents in real-life settings likely stems from limited data suggesting lower efficacy and higher toxicity. This minireview will aim to highlight current outcome measurements as it portends the elderly IBD patient, as well as summarize the available therapeutic strategies in view of a growing body of evidence.

A review of vedolizumab and ustekinumab for the treatment of inflammatory bowel diseases

Recent advancement in the understanding of the pathophysiology of inflammatory bowel disease has seen an expansion in therapeutic options. Vedolizumab, a selective α4β7 inhibitor, and ustekinumab, an IL 12/23 p40 inhibitor, have provided the much-awaited out-of-class alternatives for patients who have failed or who are intolerant to anti-Tumor Necrosis Factor (TNF) therapy. However, questions remain as to how we may best use these novel therapeutic agents. We evaluate the evidence available from randomized controlled trials and postmarketing cohort studies and discuss their safety, efficacy, and limitations, in relation to anti-TNF therapy, in optimizing the treatment outcomes.

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.

The impact of biologic agents on health-related quality of life outcomes in patients with psoriasis

INTRODUCTION

Psoriasis is a common, immune-mediated skin disease often associated with significant physical and psychosocial impairment. Antipsoriatic biologic agents offer patients unparalleled treatment potential in regard to greater skin clearance and overall improved quality of life. Evaluation of the therapeutic efficacy of biologic agents on the full psoriasis disease burden must account for their impact on both physical symptoms, as well as patient-reported, health-related quality of life (HRQoL) measurements. Areas covered: Results from numerous clinical trials demonstrate the significant clinical efficacy of biological agents targeting tumor necrosis factor-α (TNF-α) and the interleukin (IL)-12/23 and IL-17 immune pathways. However, relatively limited data is available evaluating their full effect on quality of life outcomes. This review will discuss the most relevant and up-to-date clinical data on HRQoL measurements related to treatment with these aforementioned biologic agents. Expert commentary: Patient-reported outcomes (i.e. Dermatology Life Quality Index) are being used with increasing frequency in clinical trials, and provide valuable information on the impact of psoriasis on numerous aspects of day-to-day living. These outcomes must also be incorporated in clinical practice, in addition to physical assessment of disease severity, treatment decisions, and therapeutic response in the psoriasis patient population.

Vitamin D and its role in psoriasis: An overview of the dermatologist and nutritionist

Psoriasis is a chronic immune-mediated inflammatory skin disease. Psoriasis lesions are characterized by hyper-proliferation of epidermal keratinocytes associated with inflammatory cellular infiltrate in both dermis and epidermis. The epidermis is the natural source of vitamin D synthesis by sunlight action. Recently, a role for vitamin D in the pathogenesis of different skin diseases, including psoriasis, has been reported. Indeed, significant associations between low vitamin D status and psoriasis have been systematically observed. Due to its role in proliferation and maturation of keratinocytes, vitamin D has become an important local therapeutic option in the treatment of psoriasis. To date, the successful treatment based on adequate dietary intake of vitamin D or oral vitamin D supplementation in psoriasis represent an unmet clinical need and the evidence of its beneficial effects remains still controversial. This information is important either for Dermatologists and Nutritionists to increases the knowledge on the possible bi-directional relationships between low vitamin D status and psoriasis and on the potential usefulness of vitamin D in psoriasis with the aim not only to reduce its clinical severity, but also for delineating the risk profile for co-morbidities cardiac risk factors that may result from psoriasis. In the current review, we analyzed the possible bi-directional links between psoriatic disease and vitamin D.

Italian guidelines on the systemic treatments of moderate-to-severe plaque psoriasis

Psoriasis is a common disease, which has a considerable impact on the healthcare system. Therefore, appropriate use of therapeutic resources is very important. Management of psoriasis in daily clinical practice is highly variable because many issues are still debated and not definitely addressed by the evidence-based medicine. Moreover, the different availability and reimbursability of drugs in each country justifies national guidelines. Expert consensus can provide helpful guidelines for optimizing patient care. A total of 20 dermatologists from different areas of Italy and with large experience in the treatment of psoriasis agreed to participate in the guidelines expert panel who aimed to reach consensus on the factors influencing psoriasis severity, the indications for systemic treatments, the parameters to be considered in the choice of treatment, and the factors to be considered in the choice of biological treatment. The recommendations for the use, screening and monitoring of systemic therapies were based on the 2015 S3 European Dermatology Forum/European Academy of Dermatology and Venereology psoriasis guidelines. Recommendations on the treatment of psoriasis in special patient populations were also agreed. The final document was discussed in a meeting moderated by a facilitator with participation of the entire group and adopting a nominal group technique to reach consensus. A statement was regarded as consented when agreement was achieved by at least 75% of the voting experts according to the Delphi procedure.

Efficacy and safety of infliximab in psoriatic patients over the age of 65

BACKGROUND

Clinical data on the long-term safety and efficacy of infliximab on psoriatic patients who are older than 65 years are limited.

OBJECTIVES

The aim is to report the long-term efficacy, safety and tolerance of infliximab in geriatric patients.

METHODS

This was a retrospective study conducted at the Department of Dermatology of the University of Rome Tor Vergata. Clinical data were reported at week 12, 52, 104, 208.

RESULTS

151 charts were evaluated. A total of 27 patients were included. Range of the age was between 65 and 85 years; mean age was 73 years ±5.4; female to male ratio was 1:2; mean age of onset of psoriasis was 43 years±17. The average of treatment duration was 39 months ±27 (range 1-100). Fourteen patients suffered from plaque type psoriasis and 13 from psoriatic arthritis. At the baseline the mean PASI score was 15.6 ± 10.2. At week 12, 52, 104, and 208 the mean PASI was 2, 2.3, 1.9 and 1.8 respectively. A reduction in the mean PASI was maintained in the long-term treatment in 12 patients (p < 0.001).

CONCLUSION

Our data suggest that long-term treatment with infliximab is effective and safe in patients over 65 years old and that IV therapy is also associated with a high compliance.
