Unmet Personal Patient Needs in Psoriasis Patients with Low Disease Activity on Adalimumab, Etanercept or Ustekinumab.

BACKGROUND: Personal treatment goals have been systematically investigated in psoriasis patients with active but not in controlled disease. OBJECTIVES: To explore patient needs in psoriasis patients with controlled disease due to biologic therapy with adalimumab, etanercept or ustekinumab. METHODS: Treatment needs in patients on adalimumab, etanercept or ustekinumab with a stable low disease activity for ≥ 6 months and preferably a Psoriasis Area and Severity Index (PASI) < 5, were explored with the Patient Needs Questionnaire (PNQ). Goal importance was expressed as overall mean importance score, percentage of patients that reported a goal to be quite/very important, and per PNQ subscale. Data were analysed separately for treatment, gender, age group (< 50 vs. ≥ 50 years), biologic naivety and willingness to participate in a pragmatic dose-reduction strategy. RESULTS: Sixty-five patients were included. 'To be free of itching', 'to be healed of all skin defects' and 'to have confidence in the therapy' were rated quite/very important in 78.5% of the patients, followed by 'to have no fear the disease will progress' (75.4%) and 'to get better skin quickly' (75.4%). Goals related to the subscale 'confidence in healing' were still of high importance in controlled disease. Least importance was attributed towards social goals. For female patients, it was significantly more important than for males to 'feel less depressed' and 'be comfortable showing yourself more in public'. CONCLUSIONS: Psoriasis patients with controlled disease still report substantial treatment needs, with high importance ascribed to confidence in healing. To apply personalized medicine, treatment needs should be explored on an individual level.

In psoriasis patients, a large reduction in disease severity can lead to a significant improvement in health-related quality of life. In addition to quality-of-life measurements, individual treatment goals can be assessed to evaluate patients' preferences regarding their psoriasis treatment. As opposed to patients with more severe psoriasis, unmet treatment needs in psoriasis patients with stable, low disease activity have barely been reported. In this study, the personal treatment aims of patients with controlled disease due to treatment with adalimumab, etanercept or ustekinumab were explored using the Patient Needs Questionnaire. Sixty-five patients with sustained low disease activity for ≥ 6 months were included. We found that despite low disease activity, these patients still have substantial patient needs. Patients attributed the highest importance to goals on confidence in healing, in contrast to social goals, which were valued of least importance. For female patients, it was significantly more important to 'feel less depressed' and 'be comfortable showing yourself more in public' compared to male patients. Previous treatment with biologic therapy was not associated with an altered attitude towards specific treatment goals. Our population with low disease activity seemed to award a lower level of importance to all treatment goals compared to groups of patients with more severe psoriasis that have been described in literature. Since treatment goals differ per patient, individual treatment could be optimized by actively inquiring about the patient's personal treatment goals. Clinicians should be aware that even in patients with controlled disease, substantial personal treatment needs remain.

Response to IL-17A inhibitors secukinumab and ixekizumab cannot be explained by genetic variation in the protein-coding and untranslated regions of the IL-17A gene: results from a multicentre study of four European psoriasis cohorts.

BACKGROUND: Genetic predictors for treatment response could optimize allocation of biological treatment in patients with psoriasis. There is minimal knowledge about pharmacogenetics of anti-IL-17 agents. OBJECTIVES: To assess whether genetic variants in the protein-coding region or untranslated regions of the IL-17A gene are associated with response to IL-17A inhibitors in patients with psoriasis. METHODS: This was a multicenter European cohort study investigating pharmacogenetics of IL-17A inhibitors in patients with psoriasis. Patients with plaque psoriasis treated with secukinumab or ixekizumab in daily practice were included. For all participants, the protein-coding region and untranslated regions of the IL-17A gene were analysed using Sanger sequencing. Identified genetic variants were tested for association with response to secukinumab/ixekizumab, measured as ∆PASI, after 12 weeks (primary outcome) and after 24 weeks (secondary outcome). Association was tested using a linear regression model with correction for baseline PASI as a fixed covariate and for biological naivety and body mass index as additional covariates. RESULTS: In total, 134 patients treated with secukinumab or ixekizumab were included. Genotyping of the cohort identified genetic variants present in untranslated regions and intronic DNA, but not in the protein-coding region of the IL-17A gene. Five genetic variants in non-coding DNA with a known or suspected functional effect on IL-17A expression were selected for association analyses: rs2275913, rs8193037, rs3819025, rs7747909 and rs3748067. After 12 weeks, 62% of patients achieved PASI75 and 39% achieved PASI90. At week 24, PASI75 and PASI90 response rates were 72% and 62%, respectively. No associations were found between the five genetic variants and ∆PASI, PASI75 or PASI90 after 12 and 24 weeks of anti-IL-17A treatment. CONCLUSIONS: Response to IL-17A inhibitors secukinumab and ixekizumab cannot be explained by genetic variation in the protein-coding and untranslated regions of the IL-17A gene. Pharmacogenetics of IL-17A inhibitors in the treatment of psoriasis requires further exploration.

A systematic review of pharmacogenetic studies on the response to biologics in patients with psoriasis.

BACKGROUND: Biologics are indicated for treating moderate-to-severe psoriasis. As the number of biologics registered for the treatment of psoriasis increases, so does the need for biomarkers to guide personalized therapeutic decisions. Genetic variants might serve as predictors for treatment response, a field of research known as pharmacogenetics. OBJECTIVES: To assess which genetic variants are associated with response to biologics in patients with psoriasis according to current literature. METHODS: A systematic search was performed in Embase, MEDLINE, the Cochrane Library and Web of Science. In total, 26 papers were included in this systematic review; 24 original studies and two meta-analyses. Quality was assessed using a predesigned form and risk of bias was assessed using the Newcastle-Ottawa Scale. RESULTS: The majority of studies reported a candidate gene approach, focusing on polymorphisms in genes related to the therapeutic target or to psoriasis susceptibility. Studied populations were small and results were divergent, especially for studies investigating tumour necrosis factor inhibitors. The evidence for the role of HLA-Cw6 in ustekinumab efficacy shows minimal heterogeneity, with a higher response rate among patients who were positive for HLA-Cw6 reported across three of five studies. CONCLUSIONS: Pharmacogenetic studies in psoriasis have generated divergent results. Replication of findings in larger cohorts is required. Large-scale hypothesis-free searches for genetic biomarkers are needed to uncover the complete genetic background of outcomes for treatment with biologics.

Improving the applicability of guidelines on nonmelanoma skin cancer in frail older adults: a multidisciplinary expert consensus and systematic review of current guidelines.

BACKGROUND: Balancing treatment decisions in frail older adults with nonmelanoma skin cancer (NMSC) can be challenging. Clinical practice guidelines (CPGs) could provide assistance. OBJECTIVES: To collect and prioritize items related to frail older adults with NMSC for integration into CPGs and to assess the current extent of this integration. METHODS: Items were collected and prioritized by a multidisciplinary working group (29 members) using a modified Delphi procedure and a five-point Likert scale. To assess current integration of these items in CPGs, a systematic review was subsequently performed by two independent reviewers using five medical databases (PubMed, Embase, Cochrane Library, SUMsearch and Trip Database), websites of guideline developers/databases, and (inter)national dermatological societies. RESULTS: Prioritization of a final 13-item list showed that 'limited life expectancy' (4·5 ± 0·9) and 'treatment goals other than cure' (4·4 ± 0·7) were most desired to be integrated into CPGs; both were included in six (46%) of the CPGs found (n = 13). Attention to 'tumour characteristics' and 'comorbidities' were included in CPGs most often (100% and 77%, respectively). CONCLUSIONS: More attention to items related to frail older adults in NMSC CPGs is broadly desired, but CPG integration of these items is currently limited. More integration might stimulate more holistic, personalized and patient-centred care in frail older adults.
