Experience and caring needs of patients with psoriasis: A qualitative meta-synthesis

BACKGROUND

As a chronic skin disease, psoriasis often affects the physical, psychological and social status of the patient, which in turn impacts on their experience of illness and needs. However, there is no review of qualitative research that integrates and analyses the experiences and needs of these three influences from a holistic perspective.

METHODS

This review follows the ENTREQ guidelines. Six English databases (JBI, Cochrane Library, PubMed, PsyINFO, CINAHL and Embase) and three Chinese databases (CNKI, VIP and Wanfang) were searched from January 2012 to October 2022. Literature was included if it was relevant to the experience of illness and caring needs of patients with psoriasis. The JBI-QARI was used to rate the quality of included studies.

RESULTS

Eleven studies were included in the meta-synthesis. Four analytical themes were identified for analysis: physical challenges, psychological discomfort, social phenomena and caring needs.

CONCLUSIONS

The combined physical, psychological and social effects of psoriasis and the consequent caring needs should be emphasised. Health professionals, including doctors and nurses, should be aware of the multiple changes in patients and their coping strategies, provide information about psoriasis, monitor and follow-up regularly over time and obtain feedback to inform further treatment and care so as to develop high-quality therapeutic interventions to help and guide patients with their coping strategies.

RELEVANCE TO CLINICAL PRACTICE

These findings describe the physical, psychological and social experiences of illness and caring needs of patients with psoriasis. Healthcare professionals should be more aware of patients' easily overlooked psychological and social distress, providing prompt attention and recognition of patients' experiences and needs, offering relevant assistance and support and enhancing daily, regular follow-up to help them improve their understanding of and ability to manage their illness.

Comparison of Perceptions of Skin Condition, Product Use and Allergen Reactivity Between People with Psoriasis and Controls in the European Dermato-Epidemiology Network (EDEN) Fragrance Study

Psoriasis, a chronic inflammatory skin disease, goes beyond visible symptoms and affects the general well-being of patients. The aim of this study is to understand how patients with psoriasis perceive their skin characteristics and reactivity to allergens. The study population includes 11,283 participants within the European Dermato-Epidemiology Network (EDEN) Fragrance study, covering several European regions. The study compared perceptions of skin dryness, sensitivity, product avoidance and reactivity to allergens between patients with psoriasis and controls, evaluating the potential influence of psoriasis severity. The results showed that subjects with psoriasis reported dry skin (71.1%) and sensitive skin (49.4%) more often than did controls (51.6% and 38.5%, respectively). Psoriasis patients were more likely to avoid specific products. Interestingly, there were no significant differences in patch-test results between the 2 groups and the severity of psoriasis did not have a consistent impact on these perceptions. In conclusion, people with psoriasis tend to perceive their skin as drier and more sensitive. Notably, the severity of psoriasis did not consistently influence these perceptions and objective reactivity to allergens did not align with subjective perception. Understanding these aspects is crucial for tailoring treatments to improve the well-being of patients with psoriasis, which warrants further research to explore subjective perceptions of skin well-being in patients with psoriasis.

Speed of clinical improvement in the real-world setting from patient-reported Psoriasis Symptoms and Signs Diary: Secondary outcomes from the Psoriasis Study of Health Outcomes through 12 weeks

BACKGROUND

Rapid skin improvement is a key treatment goal of patients with moderate-to-severe psoriasis (PsO).

OBJECTIVES

To compare the speed of clinical improvement of approved biologics on the symptoms and signs of psoriasis assessed by patients using the validated Psoriasis Symptoms and Signs Diary (PSSD) through 12 weeks.

METHODS

Psoriasis Study of Health Outcomes (PSoHO) is an international, prospective, non-interventional study that compares the effectiveness of anti-interleukin (IL)-17A biologics versus other biologics, together with pairwise comparisons of ixekizumab versus five individual biologics in patients with PsO. Using the PSSD 7-day recall period, patients assessed the symptoms (itch, skin tightness, burning, stinging and pain) and signs (dryness, cracking, scaling, shedding/flaking, redness and bleeding) of their psoriasis (0-10). Symptom and sign summary scores (0-100) are derived from the average of individual scores. Percentage change in summary scores and proportion of patients with clinically meaningful improvements (CMI) in PSSD summary and individual scores are evaluated weekly. Longitudinal PSSD data are reported as observed with treatment comparisons analysed using mixed model for repeated measures (MMRM) and generalized linear mixed models (GLMM).

RESULTS

Across cohorts and treatments, eligible patients (n = 1654) had comparable baseline PSSD scores. From Week 1, the anti-IL-17A cohort achieved significantly larger score improvements in PSSD summary scores and a higher proportion of patients showed CMIs compared to the other biologics cohort through 12 weeks. Lower PSSD scores were associated with a greater proportion of patients reporting their psoriasis as no longer impacting their quality-of-life (DLQI 0,1) and a high level of clinical response (PASI100). Results also indicate a relationship between an early CMI in PSSD score at Week 2 and PASI100 score at Week 12.

CONCLUSIONS

Treatment with anti-IL-17A biologics, particularly ixekizumab, resulted in rapid and sustained patient-reported improvements in psoriasis symptoms and signs compared with other biologics in a real-world setting.

Experiences and coping behaviours of patients with psoriasis: a qualitative study

BACKGROUND

Psoriasis is a complex, chronic, lifelong inflammatory skin disease characterized by the development of erythematous, indurated, scaly, pruritic and often painful skin plaques, and it is currently incurable. It profoundly affects psychological wellbeing and social functioning and has significant associated co-morbidities. To improve clinical approaches, understanding of the experiences of patients with psoriasis is needed.

OBJECTIVE

To explore the experiences and coping behaviours of patients with psoriasis.

METHODS

A qualitative study approach was conducted. Through semi-structured interviews, 20 patients with psoriasis were recruited from general practices and specialist dermatology practices in a regional teaching hospital in Taiwan. Recorded interviews were transcribed and analysed by content analysis.

RESULTS

Three themes and nine subthemes were identified: 1. Symptoms distress: (a) trouble with scaling, (b) bothersome itching, and (c) complex pain experiences; 2. Psychological distress: (a) encountering discrimination and (b) feeling stigmatised; 3. Managing psoriasis: (a) coping with symptoms, (b) seeking alternative methods, (c) using biologic agents, and (d) changing thinking and coexisting with the disease.

CONCLUSION

The experience of patients with psoriasis has significant negative impacts on their lives. The findings of this study can provide healthcare professionals with a reference for the care of patients with psoriasis.

Dermatological Conditions Inducing Acute and Chronic Pain

Pain is a common condition in dermatology. The aim of this review is to analyse the characteristics of pain in dermatology. Some skin diseases are conventionally known to cause pain; e.g. ulcers, pyoderma gangrenosum and herpes zoster. Common dermatoses, such as psoriasis or atopic dermatitis, can also cause significant pain. Some conditions are characterized by neuropathic pain and/or pruritus, without visible primary lesions: e.g. the neurocutaneous diseases, including small fibre neuropathies. Patients often fear pain in skin surgery; however, surgical procedures are rather well tolerated and any pain is mainly due to administration of local anaesthetic. Some therapies may also be uncomfortable for the patient, such as photodynamic therapy or aesthetic procedures. Thus, pain in dermatology is common, and its aetiology and characteristics are very varied. Knowledge of the different situations that cause pain will enable dermatologists to propose suitable analgesic solutions.

A comprehensive, tri-national, cross-sectional analysis of characteristics and impact of pruritus in psoriasis

BACKGROUND

Pruritus is prevalent in psoriasis but still many features of pruritus, its response to therapy and its burden in psoriasis remain to be better characterized.

OBJECTIVE

To investigate characteristics and burden of pruritus in an international cohort of patients with psoriasis.

METHODS

This cross-sectional study included a total of 634 patients and 246 controls from Germany, Poland and Russia. Physicians examined and interviewed participants, recording clinical characteristics, such as severity, therapy and localization of psoriatic lesions. Participants filled out self-reported questionnaires including questions on pruritus severity and impact, characteristics, and response to therapy, and quality of life (QoL). Localization patterns of pruritus and skin lesions were visualized using body heat maps.

RESULTS

Most patients (82%) experienced pruritus throughout their disease, and 75% had current pruritus. The majority of patients (64%) perceived pure pruritus, and those who reported additional painful and/or burning sensations (36%) reported overall stronger pruritus. The scalp was the most frequently reported localization of pruritus, even in the absence of skin lesions. Body surface area (BSA) of pruritus was not linked to pruritus intensity, but to BSA of psoriatic lesions (rho = 0.278; P < 0.001). One third of patients (31%) reported impaired sex-life, and 4% had suicidal ideations due to pruritus. In up to one third of patients, psoriasis therapies had little or no effect on pruritus. The only therapeutic option offered to some of these patients were antihistamines, which appeared to be effective in most cases.

CONCLUSION

Pruritus is highly prevalent in psoriasis and is linked to a significant burden. Current psoriasis therapies are frequently insufficient to control pruritus. Managing psoriasis should include the assessment and control of itch. Efficient antipruritic therapies should be developed and be made available for patients with psoriasis.

The 5-HT1A receptor agonist, 8-OH-DPAT, attenuates long-lasting pain in imiquimod-induced psoriasis in mice

Psoriasis pain is a common symptom underestimated and rarely evaluated in psoriasis clinical trials. This work aimed to investigate whether the development of secondary chronic allodynia and hyperalgesia in the imiquimod (IMQ)-induced psoriasis mice model could be modulated by anti-inflammatory agents and compound 48/80 (C48/80) and to determine whether the activation of 5-HT_1A receptor modulates these nociceptive behaviours. C57BL/6 male mice were treated with 5% IMQ for 7 days. The paw withdrawal responses to von Frey filaments (10 and 250 mN) were used to assess the allodynia and hyperalgesia. Nociceptive behaviours were also evaluated using ketorolac 15 mg/kg s.c., adalimumab 10 mg/kg s.c. and C48/80 10 mg/kg i.p. Then, the serum serotonin and the impact of 8-OH-DPAT (1 mg/kg s.c), a 5-HT_1A receptor agonist, on long-lasting pain were examined. Mice receiving IMQ showed enhanced nociception, which decreased with all tested compounds. The serum serotonin in the IMQ group showed a significant decrease (947.042 ng/ml) regarding the control group (1143.68 ng/ml). The pretreatment with 8-OH-DPAT alleviated pain-related behaviours. These results suggest that the long-lasting pain resulting from psoriasis inflammation is also associated with the serotonergic system. The 5-HT1A receptor should be further explored as a potential therapeutic target for psoriasis pain modulation.

Disease burden, symptoms, and use of analgesics in patients with psoriasis with or without psoriatic arthritis: A cross-sectional study

BACKGROUND

Patients with psoriasis have an impaired quality of life and higher use of analgesics than the general population. Whether such use is due to skin pain or a consequence of joint pain resulting from psoriatic arthritis (PsA) is not clear.

OBJECTIVES

To assess symptoms, disease burden, and use of analgesics in patients with psoriasis with and without PsA.

METHOD

Symptoms, general health (EurQol 5-dimension and 5-levels), and use of analgesics were assessed in patients with psoriasis and the general population from the Danish Skin Cohort.

RESULTS

We included 4016 patients with psoriasis (847 with concomitant PsA) and 3490 reference individuals. For patients with psoriasis having PsA, itch, skin pain, and/or joint pain was associated with worse general health. Use of opioids within 12 months was observed among 9.0% of the general population, 14.2% of patients with psoriasis without PsA, and 22.7% of patients with concomitant PsA. Of the symptoms, only joint pain was associated with use of analgesics (odds ratio, 3.72 (2.69-5.14); P < .0001).

LIMITATIONS

Cross-sectional design.

CONCLUSION

Patients with psoriasis (especially concomitant PsA) have a higher use of analgesics compared with the general population, which appears to be a result of increased joint pain.

Complete Freund's adjuvant-induced decrement of pruriceptor-mediated suppression of itch

Peripheral inflammation is always accompanied by a noxious sensation, either pain or itch, providing a protective warning for the occurrence of pathological changes; however, the mechanisms determining whether pain, itch, or both will be elicited under certain inflammatory statuses are still far from clear. Complete Freund's adjuvant (CFA) contains heat killed and dried Mycobacterium tuberculosis widely used to induce inflammatory pain models, but how CFA treatment affects itch sensation and the possible mechanisms are still unclear. In this study, using itch behavior testing and calcium imaging, we showed that both the behaviors and calcium responses associated with Transient Receptor Potential Vanilloid 1 (TRPV1)-mediated histamine-dependent itch and Transient Receptor Potential Ankyrin 1 (TRPA1)-mediated histamine-independent itch were significantly suppressed by CFA treatment. Furthermore, to explore the possible cellular mechanisms, high-throughput single-cell RNA sequencing and real-time PCR were used to detect CFA-induced changes of itch-related genes in dorsal root ganglion (DRG) neurons. Our results revealed that although both nociceptive Trpv1+ and Trpa1+ DRG neurons were increased after CFA treatment, most known pruriceptors, including Hrh1+, Mrgpra3+, Mrgprd+, Htr3a+, Htr1f+, IL31ra+, Osmr+, and Lpar3+ DRG neurons, were significantly decreased, which may explain that CFA treatment caused itch suppression. This study indicated that itch sensation was affected after CFA treatment, although negatively, and comprehensive but not specific suppression of different pruriceptors was observed after CFA treatment, suggesting that a unified adaptive change of increased pain and decreased itch will occur simultaneously under CFA-induced inflammatory conditions.

Psoriasis is Associated with a High Comedication Burden: A Population Based Register Study

Introduction

A large body of evidence supports the association between psoriasis and concomitant diseases. However, the study of comedication for these diseases in patients with psoriasis is limited. The current study aimed to investigate the prescription and drug dispensation for comorbidity associated with psoriasis.

Methods

We conducted a retrospective case-control study from 9 April 2008 until 1 January 2016 using an electronic medical records database covering the entire population of the County of Jönköping and the Swedish Prescribed Drug Register. ICD-10 and Anatomical Therapeutic Chemical codes were used to identify patients with psoriasis and dispensed pharmaceutical prescriptions. Individuals without psoriasis were selected as controls. Patients receiving systemic treatment for psoriasis were considered as having moderate-severe psoriasis. Odds ratios for being dispensed pharmaceutical prescriptions and differences in mean number of dispensed prescriptions were explored.

Results

A total of 4587 patients with psoriasis were identified in the medical records, and 268,949 individuals served as controls. Patients with psoriasis had a significantly higher number of different drug dispensations compared to controls. Only 1.3% of all patients with psoriasis were without any prescription (excluding medication for psoriasis) during the study period while the number in the general population was 9.3%. Sex- and age-adjusted odds ratios for dispensation of drug groups related to comorbid disease were significantly higher among patients with psoriasis including drug groups such as anxiolytics and sedatives as well as drugs targeting COPD, migraine and erectile dysfunction. The most frequently dispensed comedications were oral antibiotics and analgesics including an increased risk for dispensation of opioids. Sex predisposed dispensation frequency for a variety of drug groups. Drugs targeting obesity, osteoporosis, psychiatric disease and anti-mycotics/-fungals were more frequent among women.

Conclusion

Patients with psoriasis have significantly increased numbers of different dispensed prescriptions than those without psoriasis. This underlines previous findings on increased comorbidity and health care costs for patients with psoriasis.
