Managing Mild-to-Moderate Psoriasis in Elderly Patients: Role of Topical Treatments

Medicinal Treatment of Elderly Psoriasis Patients before and after Entering a Nursing Home

Psoriasis (PS) is a chronic inflammatory skin disease, and it increasingly appears also in the elderly population. There is a rising interest in drug therapy for PS, especially for people receiving care in nursing homes (NH). Which PS-related drugs are prescribed in the time before nursing home admission (NHA), and to what extent does the supply of drugs change after NHA? Which specialties prescribe PS-related drugs? Statutory health insurance data were examined for people with PS, aged ≥ 65 years, who were newly admitted to a NH in the period 2011-2014 and observed for one year before and after NHA. Changes in prescription prevalence (pre-post comparison) were examined for significant differences. Prescriptions of PS-relevant drugs were measured by defined daily dose and stratified according to the prescribing specialist group. The analysis included 718 insured persons with PS (76.2% female, mean age 83.3 years). Systemic therapeutics played a minor role (pre: 2.6% vs. post: 2.1%) in drug therapy. Topical steroids had a high share of about 40% in the pre-post comparison. Overall, the proportion of people with PS who received treatment remained at a comparable level before and after NHA. A structured assessment of the skin is crucial, specifically in people with cognitive impairment.

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.

Real-World Effectiveness and Safety of Apremilast in Older Patients with Psoriasis

INTRODUCTION

Apremilast is a drug recently developed for psoriasis. Few data are available on its use in the elderly. We evaluated the tolerance and effectiveness of apremilast used in daily practice for psoriasis treatment in older patients.

METHODS

We performed a multicenter, retrospective study involving patients aged ≥ 65 years who had received apremilast as a psoriasis treatment. Demographic data and details regarding psoriasis and adverse events (AEs) were collected from patient medical records.

RESULTS

135 patients were included (mean age: 73.5 years). Treatment was stopped in 74 patients (54.8%) for AEs (n = 43, 56.6%), primary failures (n = 18, 23.4%), and relapses (n = 7, 9.2%). When patients were stratified by age at treatment initiation, the main cause of discontinuation in patients ≥ 75 years was AEs, whereas in patients aged 65-74 years it was primary failures (28.3%). Sixty-one patients reported AEs, mainly digestive (n = 49). Regarding effectiveness, 45.2% of patients reached PGA 0/1 between 3 and 6 months after treatment initiation. One-year apremilast continuation rates were better in the 65-74 and 75-84 years subgroups than in the > 85 years subgroup (p = 0.01).

CONCLUSION

Apremilast seems to be an effective and safe therapeutic option for psoriasis in the elderly. The main AEs reported by patients did not seem to differ from those reported previously in younger populations. However, AEs were more frequent in patients > 75 years old leading to more frequent discontinuation of apremilast compared with younger patients, suggesting a higher level of vigilance is needed in the elderly.

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.

Pharmacological plasticity-How do you hit a moving target?

Paul Ehrlich's concept of the magic bullet, by which a single drug induces pharmacological effects by interacting with a single receptor has been a strong driving force in pharmacology for a century. It is continually thwarted, though, by the fact that the treated organism is highly dynamic and the target molecule(s) is (are) never static. In this article, we address some of the factors that modify and cause the mobility and plasticity of drug targets and their interactions with ligands and discuss how these can lead to unexpected (lack of) effects of drugs. These factors include genetic, epigenetic, and phenotypic variability, cellular plasticity, chronobiological rhythms, time, age and disease resolution, sex, drug metabolism, and distribution. We emphasize four existing approaches that can be taken, either singly or in combination, to try to minimize effects of pharmacological plasticity. These are firstly, to enhance specificity using target conditions close to those in diseases, secondly, by simultaneously or thirdly, sequentially aiming at multiple targets, and fourthly, in synchronization with concurrent dietary, psychological, training, and biorhythm-synchronizing procedures to optimize drug therapy.
