Mental Health Self-Assessment in Patients With Moderate to Severe Psoriasis: An Observational, Multicenter Study of 1164 Patients in Spain (The VACAP Study)

Defining well-being in psoriasis: A Delphi consensus among healthcare professionals and patients

Psoriasis is a chronic skin disease that negatively impacts on patient's life. A holistic approach integrating well-being assessment could improve disease management. Since a consensus definition of well-being in psoriasis is not available, we aim to achieve a multidisciplinary consensus on well-being definition and its components. A literature review and consultation with psoriasis patients facilitated the design of a two-round Delphi questionnaire targeting healthcare professionals and psoriasis patients. A total of 261 panellists (65.1% patients with psoriasis, 34.9% healthcare professionals) agreed on the dimensions and components that should integrate the concept of well-being: emotional dimension (78.9%) [stress (83.9%), mood disturbance (85.1%), body image (83.9%), stigma/shame (75.1%), self-esteem (77.4%) and coping/resilience (81.2%)], physical dimension (82.0%) [sleep quality (81.6%), pain/discomfort (80.8%), itching (83.5%), extracutaneous manifestations (82.8%), lesions in visible areas (84.3%), lesions in functional areas (85.8%), and sex life (78.2%)], social dimension (79.5%) [social relationships (80.8%), leisure/recreational activities (80.3%), support from family/friends (76.6%) and work/academic life (76.5%)], and satisfaction with disease management (78.5%) [treatment (78.2%), information received (75.6%) and medical care provided by the dermatologist (80.1%)]. This well-being definition reflects patients' needs and concerns. Therefore, addressing them in psoriasis will optimise management, contributing to better outcomes and restoring normalcy to the patient's life.

Prevalence and Odds of Anxiety Disorders and Anxiety Symptoms in Children and Adults with Psoriasis: Systematic Review and Meta-analysi

The magnitude of the association between psoriasis and depression has been evaluated, but not that between psoriasis and anxiety. The aim of this systematic review and meta-analysis was to examine the prevalence and odds of anxiety disorders and symptoms in patients with psoriasis. Five medical databases (Cochrane Database, EMBASE, PubMed, PsychINFO, ScienceDirect) were searched for relevant literature. A total of 101 eligible articles were identified. Meta-analysis revealed different prevalence rates depending on the type of anxiety disorder: 15% [95% confidence interval [CI] 9–21] for social anxiety disorder, 11% [9–14] for generalized anxiety disorder, and 9% [95% CI 8–10] for unspecified anxiety disorder. There were insufficient studies assessing other anxiety disorders to be able to draw any conclusions on their true prevalence. Meta-analysis also showed a high prevalence of anxiety symptoms (34% [95% CI 32–37]). Case-control studies showed a positive association between psoriasis and unspecified anxiety disorder (odds ratio 1.48 [1.18; 1.85]) and between psoriasis and anxiety symptoms (odds ratio 2.51 [2.02; 3.12]). All meta-analyses revealed an important heterogeneity, which could be explained in each case by methodological factors. The results of this study raise the necessity of screening for the presence of anxiety disorders, as previously recommended for depressive disorders, in patients with psoriasis and, if necessary, to refer such patients for evaluation by a mental health professional and appropriate treatment.

Demographic data, comorbidities, quality of life, and survival probability of biologic therapy associated with sex-specific differences in psoriasis in the Czech Republic

BIOREP is a Czech registry of patients with psoriasis undergoing biological treatment. The objective of the study was to compare differences in demographic data, previous therapy, comorbidities, severity of psoriasis, quality of life, drug survival rates, and reasons for discontinuation between men and women. We analyzed a cohort of patients from the registry treated between May 2005 and January 2020. The total study population of 2472 patients (4051 treatment series) included 913 females and 1559 males. Women were significantly older than men at the onset of the biological treatment (47.8 vs 45.4 years, P < .0012) and the mean durations of psoriasis and that from its diagnosis until initiation of biological therapy, were longer in women (29.6 vs 27.2 years and 23.2 vs 20.6 years, P < .0012). Women as compared with men were also more often diagnosed with psoriatic arthritis (43.5% vs 33.0%, P < .0012). The prevalence rate of comorbidities was equivalent for both sexes except for that of depression (11.4% females vs 3.7% males, P < .0012). Both the DLQI and PASI scores were significantly different at baseline (DLQI = 16.0 and PASI = 19.5 for men vs DLQI 17.6 = and PASI = 17.7 for women, P < .0012). The survival probability with biological therapy was significantly lower in women for both biologically naïve and non-naïve patients, and there was more evidence of adverse effects in women. Our research demonstrates significant differences relative to multiple factors associated with psoriasis between men and women.

Emotions, Alexithymia, and Emotion Regulation in Patients With Psoriasis

Psoriasis is a chronic dermatological condition that is frequently associated with problematic patterns of emotional reactivity (the way in which patients react to stimuli), alexithymia (their ability to recognize and label the emotional reaction), and emotion regulation (the ability to enhance or reduce their own emotional reaction). A research in the peer-reviewed scientific literature was conducted in order to identify articles describing the association of psoriasis and affective problems. In particular, we first evaluate studies that have investigated abnormal emotional reactivity (in terms of duration, frequency, or type of the experienced emotions) and its impact on patients' quality of life; next, we review the role of alexithymia and emotion regulation in modulating the relationship between emotional reactivity and quality of life in this population. From a critical analysis of the reviewed studies, we highlight that altered emotional processing might be particularly important in the characterization of this condition. In particular, we show that this condition is related to an emotional reactivity characterized by negative emotions that have a stronger impact on patients' quality of life when emotion regulation abilities are weak, especially if patients have alexithymia. Finally, we present suggestions for future directions in both clinical and research fields.

Quality of life, anxiety and depressive symptoms in patients with psoriasis: A case-control study

OBJECTIVE

To compare quality of life (QoL), anxiety and depressive symptoms, alcohol consumption and other correlates between patients with psoriasis and controls; and to identify features of psoriasis associated with lower levels of QoL.

METHOD

Case-control study including 70 subjects with moderate-severe psoriasis and 140 controls without psoriasis. All participants answered the Short Form Health Survey (SF-36), with physical and mental component scores of quality of life, and the Hospital Anxiety and Depression Scale (HADS). Among subjects with psoriasis, the Psoriasis Area and Severity Index (PASI) and the Dermatology Life Quality Index (DLQI) were used, respectively, to measure the severity of psoriasis and the impact of psoriasis on the specific quality of life.

RESULTS

Compared to controls, patients with psoriasis showed higher HADS depression score and alcohol consumption, and lower QoL. Among subjects with psoriasis, multivariate analysis showed: 1) poorer physical QoL was associated with older age, articular lesions and anxious symptoms, whereas poorer mental QoL was associated with younger age, female sex, genital lesions and depressive symptoms; 2) the higher the severity of psoriasis, the lower the level of QoL and the higher the levels of anxious or depressive symptoms; and 3) female sex and articular or genital location of lesions are linked with higher HADS scores.

CONCLUSION

Higher scores in anxiety and depression and lower QoL is common in psoriasis, especially among women and those with genital or articular lesions. Dermatologists should give special attention to this subgroup of persons with psoriasis in order to prevent future psychopathology.

Psoriasis and Depression: The Role of Inflammation

Psoriasis is a chronic, systemic inflammatory disorder with multiple comorbidities. The most common comorbidities are mental disorders, especially depression, which can interact negatively with psoriasis to produce a dangerous vicious circle. Depression in psoriasis has traditionally been explained as a response to psychosocial factors and impaired quality of life. However, a new hypothesis linking depression and psoriasis through chronic inflammation offers insights that should help to understand and treat these diseases. In this approach, new drugs and lifestyle have an important role.

Serum concentrations of interleukin 18 and 25-hydroxyvitamin D3 correlate with depression severity in men with psoriasis

Objective

Psoriasis and depression may have common mechanisms, such as systemic inflammation, dysfunction of the hypothalamic-pituitary-adrenal axis, and vitamin D₃ deficiency. Among men with psoriasis, this study examined whether depression severity was associated with serum concentrations of different metabolic and inflammatory markers.

Methods

The study included 85 men with psoriasis (mean age ± standard deviation [SD], 47 ± 14 years) and 65 men without psoriasis (mean age ± SD, 44 ± 13 years). In both groups, we measured the body mass index; blood pressure; and serum concentrations of lipids, uric acid, lipase, interleukins 6 and 18, cortisol, and 25-hydroxyvitamin D₃. All participants completed the Beck Depression Inventory. Other variables analyzed included psoriasis duration, the Psoriasis Area Severity Index, and the percentage of body surface area affected by psoriatic lesions.

Results

Compared with controls, patients with psoriasis had significantly greater depression severity, higher body mass indices, and higher serum concentrations of total cholesterol and interleukins 6 and 18; moreover, they had significantly lower serum 25-hydroxyvitamin D₃ concentrations. In patients with psoriasis, depression severity correlated positively with psoriasis duration, the Psoriasis Area Severity Index, the percentage of body surface area affected by psoriatic lesions, and interleukin-18 concentration. In patients with psoriasis, depression severity correlated negatively with 25-hydroxyvitamin D₃ concentration, but it did not correlate significantly with the serum concentrations of interleukin 6 and cortisol.

Conclusions

High concentrations of interleukin 18 and low concentrations of 25-hydroxyvitamin D₃ may be associated with depression severity in men with psoriasis. Thus, further studies should examine whether effective anti-inflammatory treatments or vitamin D₃ supplementation can improve depression outcomes in these patients.

Measurement of the Psychological Impact of Psoriasis on Patients Receiving Systemic Treatment

BACKGROUND AND OBJECTIVES

The negative impact of psoriasis on patient quality of life can be as important as the physical consequences of the disease. We could assume that clearance of the disease would also lead to an improvement in its psychosocial impact. The present study assesses the psychological state of patients with psoriasis receiving systemic treatment in a psoriasis unit, especially those with mild or no disease involvement.

METHODS

We performed a cross-sectional, observational, noninterventional epidemiological study of 2 cohorts (cases and controls). The patients self-completed demographic data and 4 questionnaires (Rosenberg Self-Esteem Scale, Skindex-29, HADS, and COPE-28 questionnaire) at a single visit.

RESULTS

We recruited 111 patients diagnosed with psoriasis and 109 control patients. In self-esteem, the mean and standard deviation (SD) score was 33.5 (4.8) for the psoriasis group and 33.3 (6.7) for the control group, with no significant differences. In the Skindex-29, the mean score for the psoriasis group was almost 3 times higher than that of the control group (30 vs. 11). Significant differences were found in the HADS scores of both groups (12.7 vs. 9.0, P<.001). The mean HADS-A scores were 8.0 (4.78) for the psoriasis group compared with 5.7 (3.8) for the control group (P<.001). In the case of HADS-D, the scores were 4.7 (3.9) compared with 3.2 (3.1) (P<.004), respectively.

CONCLUSIONS

Our findings indicate that it is necessary to assess the psychological state of patients with psoriasis, because psychological effects persist even in cases where the disease is almost totally controlled.

Comparison of mental health outcomes among adults with psoriasis on biologic versus oral therapies: a population-based study

PURPOSE

We sought to compare the impact of biologic versus oral therapies on mental health outcomes among adult U.S. residents with moderate-to-severe psoriasis.

METHODS

We performed a nationwide, cross-sectional study comparing 2,303,534 (weighted) adults with moderate-to-severe psoriasis on biologic versus oral therapies and their associated mental health outcomes using the 2003-2015 Medical Expenditure Panel Survey (MEPS). Mental health outcomes were measured with the Kessler 6 (K6), a validated measure of psychological distress, and Patient Health Questionnaire 2 (PHQ2), a screening tool for depression.

RESULTS

The mean K6 score for residents on biologic therapies was significantly lower than that of residents on oral therapies (2.72 [95% CI: 2.27-3.17] versus 3.70 [95% CI: 3.27-4.12]; p < .001). The mean PHQ2 score for residents on biologic therapies was also significantly lower than that of residents on oral therapies (0.540 [95% CI: 0.390-0.690] versus 0.890 [95% CI: 0.749-1.031]; p < .001). Based on adjusted multivariable linear regression models, biologic therapy was associated with significant reductions in K6 (p < .001) and PHQ2 (p = .016) scores compared to oral therapy.

CONCLUSIONS

Therapeutic choices for psoriasis impact mental health outcomes. Biologic therapy is associated with reductions in psychological distress and depression as compared to oral therapy in the U.S. adult moderate-to-severe psoriasis population.

Determinants of quality of life and psychological status in adults with psoriasis

We investigated whether disease severity and clinical manifestations were associated with depression, anxiety, stress and quality of life in adults with psoriasis. Participants were recruited from a dermatology outpatient clinic at a teaching hospital. Information on sociodemographic characteristics, disease severity, presence of arthropathy and head involvement was specifically recorded. Disease severity was assessed using the Psoriasis Area and Severity Index (PASI). Quality of life and psychological symptoms were measured using the Dermatology Life Quality Index (DLQI) and the Depression Anxiety Stress Scale (DASS), respectively. One hundred individuals were recruited. Unadjusted analysis revealed that head involvement was associated with depression [odds ratio (OR) 8.509; 95% confidence interval (CI) 1.077-67.231] and anxiety (OR 6.46; 95% CI 1.401-29.858). Severe disease was associated with a poorer quality of life compared to mild disease (OR 3.750; 95% CI 1.330-10.577). Younger age was associated with an increased risk of depression [mean difference (MD) - 8.640; 95% CI - 16.390 to - 0.890], anxiety (MD - 11.553; 95% CI - 18.478 to- 4.628), stress (MD - 11.440; 95% CI - 19.252 to - 3.628) and severely impaired quality of life (MD - 12.338; 95% CI - 19.548 to - 5.127). Following adjustments for age and disease severity, anxiety, stress and depression remained associated with severely impaired quality of life.

Depressiveness, measured with Beck Depression Inventory, in patients with psoriasis

BACKGROUND

The aim of this study was to identify demographic and clinical factors predisposing to depressiveness during the course of psoriasis.

METHOD

The study included 239 patients with psoriasis (15-76 years, 31.8% of women) and 123 healthy controls (17-74 years, 32.5% of women). Dependent variable in the analysis was Beck Depression Inventory (BDI) score. Explanatory variables included: age, sex, marital status, education, occupational activity, body mass index (BMI), systolic and diastolic blood pressure, history of smoking, average number of smoked cigarettes, skin lesions visible to others, comorbidities, including arterial hypertension and arthritis, number of previous hospitalizations and family history of psoriasis.

RESULTS

Psoriatics showed higher BDI scores than the controls, and significantly more often presented with depressiveness. Depressiveness correlated with psoriasis, older age, female sex, lack of higher education, occupational inactivity, higher BMI, visible skin lesions, comorbidities, including arterial hypertension and arthritis, greater number of previous hospitalizations and lack of family history of psoriasis. Multivariate analysis showed than independent predictors of any grade depressiveness were psoriasis (OR=2.26, 95%CI: 1.11-4.60, p=0.024), older age (OR=1.03, 95%CI: 1.01-1.05, p=0.005) and female sex (OR=2.73, 95%CI: 1.45-5.12, p=0.002).

LIMITATIONS

Cross-sectional, non-prospective analysis. Selection bias.

CONCLUSIONS

Patients with psoriasis, irrespective of its severity and related complications, are at increased risk of depressiveness. The risk of secondary depressiveness is particularly high in psoriatic women and older persons (or individuals diagnosed with psoriasis at younger age). Individuals from this group should be monitored for potential depressive symptoms.

Health-related quality of life and its association with alexithymia and difficulties in emotion regulation in patients with psoriasis

BACKGROUND

Health-related quality of life (HRQoL) in psoriasis patients could be negatively affected by medical (e.g., obesity) and psychological (e.g., depression, anxiety, and alexithymia) conditions the presence of which suggests difficulties in understanding and regulating inner states and emotions. Thus, the aim of this study was to investigate HRQoL and its association with obesity and difficulties in understanding and regulating inner states and emotions in patients with psoriasis. A second objective was to examine whether the presence of difficulties in understanding and regulating inner states and emotions may mediate the association between psoriasis and poor HRQoL.

METHOD

One hundred adult outpatients and 97 healthy controls were administered a checklist assessing major socio-demographic variables, and measures of HRQoL, difficulties in emotion regulation, alexithymia, anxiety, depression, and food craving.

RESULTS

Psoriasis patients (compared to controls) reported more frequently obesity, alexithymia, anxiety, depression and food craving, and reported lower scores on the mental and physical components of HRQoL. A mediation model, with mental health as the dependent variable, indicated significant direct and indirect (through BMI, difficulties in emotion regulation, anxiety, depression, and food craving) effects of psoriasis on the quality of life, so that psoriasis was associated with worse mental health. A second mediation model with physical health as dependent variable indicated only a significant indirect effect (through BMI and depression) of psoriasis on the quality of life.

CONCLUSIONS

Psoriasis is characterized by poor HRQoL and the presence of difficulties in understanding and regulating inner states and emotions. In patients with psoriasis the possible influence of food craving on abnormal eating habits should be carefully assessed.

Pathogenic aspects of treatment of psoriatic patients

The article describes high incidence and morbidity rate of psoriasis, substantial reduction in the life quality and psychosocial disadaptation of patients, and presents certain particular features of psoriasis pathogenesis taking into consideration the role of immune mechanisms and relation between the disease and other chronic processes in the organism, as a result of which psoriasis is considered to be a multimorbid condition. The multimorbidity of psoriasis is an important factor for selecting a therapy, especially for patients with severe forms of the disease.
