Effect of Age of Onset of Psoriasis on Clinical Outcomes with Systemic Treatment in the Psoriasis Longitudinal Assessment and Registry (PSOLAR)

Hematological ratios as an indicator of severity in alopecia areata: A retrospective nationwide study

BACKGROUND

Alopecia Areata (AA) is an autoimmune condition where the activation of Th1, Th2, and Th17 responses is known to stimulate other white blood cells, potentially affecting hematopoietic lineages. However, previous studies on AA have found no utility in hematological ratios. Our goals were to compare neutrophils-to-lymphocytes ratio (NLR), platelets-to-lymphocytes ratio (PLR), eosinophils-to-lymphocytes ratio (ELR), eosinophils-to-neutrophils ratio (ENR), and eosinophils-to-monocytes ratio (EMR) between patients with AA and controls, as well as between mild and moderate-severe AA cases.

METHODS AND FINDINGS

We performed a retrospective, population-based cohort study involving adult patients enrolled in the largest national health maintenance organization in Israel. The study comprised 147,020 AA patients and 141,598 healthy controls. AA patients exhibited a higher likelihood of elevated NLR and ELR compared to controls. Upon further classification based on severity, moderate-severe AA patients displayed higher values of NLR, PLR, ELR, and EMR compared to mild AA individuals OR = 1.11 [1.09-1.1], P<0.001; OR = 1.09 [1.05-1.13], P<0.001; OR = 2.06 [1.67-2.53], P<0.001; OR = 1.07 [1.03-1.07)], P<0.001, respectively). Similar trends were observed 12 to 18 months before diagnosis.

CONCLUSION

Our results not only deviate from the current literature but also offer a cost-effective, accessible, and efficient tool for enhanced disease prediction and management.

Psoriasis localization patterns in the Swiss Psoriasis Registry (SDNTT) over 11 years: an analysis by sex and age

Real-world data on anatomically localized psoriasis and its response to systemic therapy across different age-groups and sexes is limited. This study aimed to evaluate the severity and distribution of psoriasis over time in female and male patients receiving systemic therapies, categorized by age within the Swiss psoriasis registry (SDNTT). Patient-data was obtained over 11 years through the SDNTT. The localized Psoriasis Area and Severity Index (locPASI) of the head, trunk, upper and lower extremities was analyzed over two years following the start of systemic non-/biologic treatment. A total of 316 female and 517 male patients were analyzed. Male patients had a higher baseline locPASI for legs, trunk and arms (p < 0.001), but not for the head (p = 0.961). The locPASI for the head in younger female patients (18-40 years) had a higher score than those aged 55 + (p = 0.022) and after two years, middle aged (41-54) showed a lower score compared to younger patients (p = 0.045). Younger male patients revealed a lower score after two years of therapy in the leg- and arm-area compared to older (p = 0.018 and p = 0.048, respectively). Female patients on non-biologics had a fast initial response, converging with male patients' scores over 24 months. Over 75% locPASI reduction was observed for female head-area (81.4%), male trunk (82.7%) and legs (76.1%). Absolute locPASI ≤ 2 was achieved 3-6 months for all locations with interleukin (IL)-17, IL-12/23 and IL-23-inhibitors, except for the legs of male patients on anti-IL-17 and female patients on anti-IL-12/23 and -IL-23. After two years, male patients did not achieve a locPASI ≤ 2 for any biologic-treatment in the legs, nor for the arms on anti-TNF-α. Significant disparities in localized PASI were observed between female and male patients. The age, sex and severity of distinct localizations should be considered to optimize treatment goals.

Mitigative Effects of Topical Norfloxacin on an Imiquimod-Induced Murine Model of Psoriasis

Psoriasis is a chronic, inflammatory dermatosis characterized by thickened, reddened, and scaly skin lesions. Norfloxacin is a fluoroquinolone antibiotic with enhanced antioxidant, anti-inflammatory, and immunomodulatory bioactivities. The aim of this study was to figure out the possible impact of topical norfloxacin on an imiquimod-induced model of psoriasis in mice. Thirty albino-type mice were split into five distinct groups of six animals each. The control group included healthy mice that had not received any treatment. The induction group was given the vehicle 2 h after the topical imiquimod, once daily for 8 days. Two hours after receiving topical imiquimod, the treatment groups including calcipotriol, norfloxacin 2.5%, and norfloxacin 5% were given topical ointments containing calcipotriol 0.005%, norfloxacin 2.5%, and norfloxacin 5%, for 8 days. Topical norfloxacin ointment significantly reduced the severity of imiquimod-exacerbated psoriatic lesions including erythema, shiny-white scaling, and acanthosis and fixed histological abnormalities. Furthermore, imiquimod-subjected mice treated with a higher concentration of norfloxacin ointment exhibited dramatically lower skin levels of inflammation-related biomarkers like IFN-γ, TNF-α, IL-6, IL-17A, IL-23, and TGF-β but higher levels of IL-10. They also demonstrated a notable decrease in angiogenesis parameters such as VEGF and IL-8, a substantial reduction in oxidative indicators like MDA and MPO, and a considerable rise in antioxidant enzymes like SOD and CAT. This study offers novel evidence that norfloxacin may assist in controlling inflammatory dermatoses like psoriasis by minimizing the severity of psoriatic plaques, correcting histological alterations, and diminishing the production of inflammatory, oxidative, and angiogenetic parameters.

The association of age at psoriasis onset and HLA-C*06:02 with biologic survival in patients with moderate-to-severe psoriasis: a cohort study from the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR)

BACKGROUND

Few studies have used real-world data to investigate the association between biologic therapy survival and age at psoriasis onset or HLA-C*06:02 status in patients with moderate-to-severe psoriasis. The robustness of these studies is limited by small sample size, short follow-up and diverse safety and effectiveness measures.

OBJECTIVES

To describe biologic survival and explore whether the response to biologics is modified by age at psoriasis onset or HLA-C*06:02 status in patients with moderate-to-severe psoriasis.

METHODS

Data from patients in the UK and the Republic of Ireland registered in the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) from 2007 to 2022 on a first course of adalimumab, etanercept, secukinumab or ustekinumab with at least 6 months' follow-up and a subset of BADBIR patients with available HLA-C*06:02 information registered to Biomarkers and Stratification To Optimise outcomes in Psoriasis (BSTOP) were analysed. Patients aged ≥ 50 years at treatment initiation were classified into early-onset psoriasis (EOP) (presenting in patients ≤ 40 years of age) and late-onset psoriasis (LOP) (presenting in patients > 40 years of age). BADBIR patients with available information in BSTOP were categorized as HLA-C*06:02- or HLA-C*06:02 + . Biologic survival was defined as treatment discontinuation associated with ineffectiveness or occurrence of adverse events (AEs). Adjusted survival function and hazard ratio (aHR) with 95% confidence interval (CI) were estimated using a flexible parametric model to compare discontinuing therapy between age at psoriasis onset and HLA-C*06:02 groups. Each model included exposure (biologics), effect modifier (age at onset or HLA-C*06:02 status), interaction terms and several baseline demographic, clinical and disease severity covariates.

RESULTS

Final analytical cohorts included 4250 patients in the age at psoriasis onset group [2929 EOP (69%) vs. 1321 LOP (31%)] and 3094 patients in the HLA-C*06:02 status group [1603 HLA-C*06:02+ (52%) vs. 1491 HLA-C*06:02- (48%)]. There was no significant difference between EOP and LOP in drug survival associated with ineffectiveness or AEs for any biologics. However, compared with patients who were HLA-C*06:02-, patients who were HLA-C*06:02 + were less likely to discontinue ustekinumab for reasons associated with ineffectiveness (aHR 0.56, 95% CI 0.42-0.75).

CONCLUSIONS

HLA-C*06:02, but not age at psoriasis onset, is a predictive biomarker for biologic survival in patients with psoriasis. Findings from this large cohort provide further, important information to aid clinicians using biologic therapies to manage patients with psoriasis.

Evaluating minority representation across health care settings in hidradenitis suppurativa and psoriasis

Background

Females and minorities have been underrepresented in clinical research despite legislative efforts, including in hidradenitis suppurativa (HS) and psoriasis (PsO) clinical trials.

Objective

To identify differences in demographic breakdowns of HS and PsO patients between health care settings to uncover any causative health disparities.

Methods

This study reports racial, ethnic, and sex of HS and PsO patient populations across the emergency department (ED), inpatient, clinical trial, and registry settings. In addition, 95% confidence intervals are used as proxies of statistical significance to compare demographics between settings.

Results

Female, Hispanic, and Black patients were underrepresented in HS clinical trials compared to their population prevalence (female: 63.7% vs 73.5%; Hispanic: 3.8% vs 12.0%; Black: 9.1% vs 20.3%). Female and Black patients were underrepresented in PsO trials compared to their population prevalence (female: 33.0% vs 54.8%; Black: 2.2% vs 5.7%). Black patients were overrepresented in the inpatient and ED settings in HS (inpatient vs ED vs population prevalence: 49.9% vs 49.9% vs 20.3%) and in the inpatient setting in PsO (inpatient vs population prevalence: 19.8% vs 5.7%).

Limitations

The main limitation is the reliability and generalizability of the published studies used to compare demographics across settings.

Conclusion

Underrepresentation of females and minorities in HS and PsO clinical trials is consistent with published literature. Overrepresentation of Black patients in acute care settings is likely multifactorial.

Exploring Psoriasis Inflammatory Microenvironment by NanoString Technologies

Psoriasis is a chronic inflammatory skin disease whose molecular mechanisms and microenvironment are poorly understood. We performed gene expression analysis through the nCounter® PanCancer Immune Profiling Panel (NanoString Technologies, Seattle, WA, USA) on 22 FFPE punch biopsies from 19 psoriasis-affected patients. A subset of five cases was analyzed before (T0) and after 6 months (T6) of treatment with dimethyl fumarate (DMF) to address immune microenvironment changes. Molecular comparisons according to biopsy site and age of onset showed a different distribution of innate immune cells (mast cells, macrophages, NK cells, and DC cells) and pathways (complement regulation and transporter functions). The analysis according to PASI (Psoriasis Area and Severity Index) led to non-significant results, suggesting no link between molecular expression profile and clinical amount of skin disease. In DMF-treated patients, we observed a strong immunomodulatory effect after treatment: A subversion of exhausted CD8 T cells, NK CD56dim cells, Tregs, neutrophils, CD45+ cells, T cells, B cells, and macrophages was reported between the two analyzed time-points, as well as the reduction in pro-inflammatory pathways and molecules, including cytotoxicity, pathogen defense, antigen processing, adhesion, cell cycle, chemokines, cytokines, and interleukins. The inflammatory psoriatic microenvironment can be modulated using DMF with encouraging results, achieving an immune-tolerant and non-inflammatory condition through the regulation of both innate and adaptive immunity.

Early intervention in psoriasis: Where do we go from here?

Patients with psoriasis often have comorbidities and are at increased risk of developing several complications compared with the general population. Knowledge on the role of immune mediators and systemic inflammation in psoriasis has led to the hypothesis that early intervention with systemic therapy has the potential to modify the course of the disease and reduce the risk of long-term adverse outcomes. In this article, we address some potential issues that need to be considered before early intervention can be implemented routinely. The first is determining what constitutes "early" intervention for psoriasis. A second point is whether the intervention should be considered for patients with early disease or for selected subsets based on risk stratification. A third important consideration is defining success for early intervention. Finally, adoption of early and effective intervention should be based on high-level evidence. Ideally, randomized trials would be the best strategy to compare early vs. late systemic treatment in patients with psoriasis, probably using the frequency of long-term outcomes as primary endpoint, with cutaneous and pharmacoeconomic outcomes assessed secondarily.

Psoriasis in Northern Saudi Arabia: Clinical features and implications for quality of life

Introduction:

Psoriasis is a chronic non-contagious inflammatory skin disorder, which might impair patient’s social relationships, limit leisure activities, and lower self-esteem. Psoriasis patients might be stigmatized leading to psychological disorders such as anxiety and depression.

Objectives:

This study aimed to outline the clinical features of psoriasis and its effects on quality of life, and the feeling of stigmatization among psoriasis patients.

Methods:

This cross-sectional questionnaire-based study was conducted on 109 adult psoriasis patients in Arar City, Saudi Arabia. The study collected data on socio-demographic and clinical characteristics of psoriasis patients, self-reported psoriasis severity using the self-assessment Simplified Psoriasis Index (sa-SPI-s), patients’ quality of life using the dermatological life quality index (DLQI), and the feeling of stigmatization using the six-items stigmatization scale.

Results:

The mean age of psoriasis onset in studied patients was 20 (±7.65) years, females represented 58.72%, and 22% were unemployed. Joint and nail affection were reported in 46.79% and 51.38%, respectively. One third of patients had positive family history of psoriasis. Seasonal variation, life stressors, smoking and skin injuries were frequent provocative factors for psoriasis lesions. The average sa-SPI-s was 10.08 (±10.41), which was correlated with patients’ ages, disease duration, obesity, and pruritis. The average DLQI and six-items stigmatization scale for psoriasis patients were 8.95 (±5.77) and 7.61 (±4.5), respectively that were correlated with sa-SPI-s.

Conclusion:

The clinical manifestations and chronicity of psoriasis impaired patients’ quality of life and accompanied with social stigma due to skin disfigurement. These effects need to be addressed for better care of patients.

The Association Between Chronic Plaque Psoriasis and Nonalcoholic Fatty Liver Disease in Indian Patients: Results of a Pilot Study

BACKGROUND

Psoriasis is a chronic dermatosis with potential to cause systemic disease by triggering dysmetabolism, such as metabolic syndrome and nonalcoholic fatty liver disease (NAFLD). We studied the relationship and associations between NAFLD and clinical features, including age, gender, disease duration, and severity of psoriasis in our patients.

METHODS

This cross-sectional study comprised 61 (m:f, 43:19) patients without pre-existing comorbidities and matched 24 (m:f, 16:8) healthy controls aged between 20 and 68 years. Disease severity was graded as mild, moderate, and severe by psoriasis area and severity index score and body surface area (BSA) involvement. The grades of fatty liver and liver fibrosis were assessed using liver ultrasonography (USG) and transitional vibration-controlled elastography (Fibroscan).

RESULTS

Overall, 67.2% of patients were aged >40 years, and the duration of disease was <5years in 60.7% of patients. Mild and moderate to severe psoriasis occurred in 78.7% and 21.3% of patients, respectively. BSA was >10% in 57.5% patients. The proportion of NAFLD was 27.9% and 32.8% by USG and Fibroscan compared with 20.8% in controls. Statistically, there was no significant difference or association between the prevalence of NAFLD among patients and controls, and gender, age (mean ± standard deviation, 47.5 ± 13.8 vs. 45.2 ± 15.7), duration, severity of psoriasis, and arthritis between psoriatic patients with and without NAFLD.

CONCLUSION

This was a pilot study because of the numerosity of sample and highlights trends for possible link between psoriasis and NAFLD, but the results need cautious interpretation and clinical application. Whether NAFLD can be attributed to overall systemic inflammatory process of psoriasis or it occurs as an epiphenomenon of concurrent metabolic syndrome needs elucidation with well-designed studies. Cross-sectional study design, small number of patients, and controls remain major limitations. The study did not compare its findings with liver biopsy.

Nail Psoriasis in Older Adults: Intralesional, Systemic, and Biological Therapy

Psoriasis may affect the skin, scalp, joints, and nails and is common in older adults. Intramatrical injections with triamcinolone acetonide are safe and effective in older individuals. Conventional systemic medications are relatively effective, but side effects, including laboratory abnormalities and drug interactions, are particularly common among older adults. Biologic medications have shown excellent efficacy in treating nail psoriasis. Their safety profile is favorable, but data assessing long-term safety are lacking. Randomized controlled trials in older adults exclusively are necessary to develop evidence-based treatment guidelines in this population.

The Association of Thyroid Dysfunction with Chronic Plaque Psoriasis: A Hospital-Based Retrospective Descriptive Observational Study

BACKGROUND

Associations among thyroid dysfunction, thyroid autoimmunity, and clinical features including age, gender, disease duration, and severity of psoriasis is less studied.

OBJECTIVES

To study frequency of thyroid dysfunction and thyroid autoimmunity and examine association among thyroid dysfunction, thyroid autoimmunity, and clinical features including gender, age, duration, and severity of psoriasis.

MATERIAL AND METHODS

The medical records of 290 (m:f 2.15:1) patients aged 13-75 years with plaque psoriasis were analyzed for thyroid dysfunction and thyroid autoimmunity. Thyroid dysfunction was defined as 10% variation in any thyroid hormone levels. Thyroid autoimmunity was diagnosed from presence of antithyroid peroxide (anti-TPO) antibodies.

RESULTS

The majority, 57.9% patients, was aged ≥41 years (Type-2 psoriasis) and duration of disease was <5 years in 58.6% patients. Mild and moderate to severe psoriasis was present in 58.3% and 41.7% patients, respectively. Deranged thyroid functions were present in 29 (10%) patients. Hypothyroidism and hyperthyroidism occurred in 5.4% and 2.7% patients, respectively. Anti-TPO antibodies were observed in 13.5% patients; 11had hypothyroidism. There was no statistically significant difference in gender, age, duration, and severity of psoriasis when compared with patients having normal thyroid function tests.

CONCLUSION

The study suggests possible thyroid dysregulation and thyroid autoimmunity in psoriasis but results need careful interpretation and clinical application. Their significance as standalone risk factor for the chronicity, severity, and relapses in psoriasis or whether thyroid hormone replacement or antithyroid drugs become a useful therapeutic option remains tenuous at best for need of more robust evidence. Retrospective, observational, cross-sectional study design, small number of patients, and lack of controls remain major limitations.

Management of Paediatric Psoriasis by Paediatricians: A Questionnaire-Based Survey

INTRODUCTION

Paediatric plaque psoriasis (PedPso) in children and adolescents is often diagnosed and treated for the first time by paediatricians. An early onset of psoriasis is associated with a genetic family burden, higher severity of disease and increased risk of comorbidities, sometimes starting in childhood. However, little information is available on prevalence data and the clinical management of PedPso by paediatricians.

METHODS

A total of 191 questionnaires were sent out to paediatricians regarding their management of PedPso, with a focus on prevalence, diagnosis, initiation of therapies, screening for comorbidities and collaboration with dermatologists. Of these, 95 (49.7%) were returned and evaluated anonymously.

RESULTS

Only about one-half of the responding paediatricians reported being certain in their diagnosis of PedPso, even though they regularly see moderate-to-severely affected patients. The questionnaire revealed that there are clear differences in the general management of PedPso if the paediatrician is not certain of the diagnosis of psoriasis. Compared to paediatricians certain of their diagnosis, those who are uncertain less frequently perform whole-body inspection, screen for relevant comorbidities, such as psoriasis arthritis, metabolic syndrome or mental disorders, and prescribe the use of topical or systemic therapies. No responding paediatrician reported the use of modern systemic therapies, such as biologicals, even in severely affected children. The majority of respondents rated their cooperation with dermatologists as good.

CONCLUSION

The certainty of the diagnosis, the use of system therapies and the screening for comorbidity could improve the care of PedPso through targeted training of paediatricians and intensified interdisciplinary cooperation with dermatologist.

Intake of dietary fibre, red and processed meat and risk of late-onset Chronic Inflammatory Diseases: A prospective Danish study on the "diet, cancer and health" cohort

Background: Human and animal studies support the involvement of diet in the development of CID -chronic inflammatory diseases such as inflammatory bowel disease, psoriasis, rheumatoid arthritis, psoriatic arthritis, and multiple sclerosis. Objective: This cohort study aimed to investigate the association between intake of fibre, red and processed meat, and occurrence of late-onset CID (50+ years of age) in the DCH: Danish Diet, Cancer and Health cohort. We hypothesised that risk of late-onset CID would be lower among those with high intake of fibre and/or low intake of meat compared to individuals with low fibre and/or high meat intake. Methods: The DCH recruited 56,468 individuals, aged 50-64 years, between 1993 and 1997. At recruitment, diet intake was registered using food frequency questionnaires as well as lifestyle factors in 56,075 persons. Exposure variables were generated as sex-adjusted tertiles of fibre and meat (g/day). Development of CIDs was identified in national registries. Hazard ratios (HR) of late-onset CIDs (adjusted for age, sex, energy intake, alcohol, smoking, education, comorbidity, and civil status) were estimated for all three exposure variables. Results: During follow-up of 1,123,754 years (median (Interquartile range) = 22.2 (20.1-23.1)), 1,758 (3.1%) participants developed at least one CID. The adjusted HRs for developing CID (low fibre 1.04 [0.89-1.22] and medium fibre 1.04 [0.91-1.18] (high fibre as reference), and medium meat 0.96 [0.86-1.09] and high meat 0.94 [0.82-1.07] (low meat as reference)) or the individual diseases were not statistically significant. Conclusion: This large study did not support that a high intake of fibre and/or a low intake of meat had a high impact on the risk of late-onset CID.

Moderate to severe psoriasis: a single-center analysis of gender prevalence

BACKGROUND

Psoriasis is a chronic, relapsing disease and most epidemiological studies include selected patients undergoing systemic therapies only. Epidemiological data suggest that psoriasis affects 2-3% of the general population, and that men and women are equally affected. The objective was to identify differences in gender for disease severity, patient characteristics and comorbidities in patients with moderate to severe psoriasis, independent of therapy.

METHODS

A retrospective medical chart review of consecutive patients diagnosed with moderate-severe psoriasis at a single center between 2004 and 2017, with a complete set of medical records, was undertaken. Both univariate and multivariate regression analyses were performed. Statistical significance was defined as P<0.05.

RESULTS

The male-to-female ratio revealed a higher prevalence for male gender (2:1, P<0.05). Whilst no significant differences were found for most factors according to gender, age at first evaluation was significantly higher for women. Logistic regression analysis indicated that autoimmune/autoinflammatory diseases were more frequently observed in women, as well as phenotypes other than plaque psoriasis and hypertension. Inversely, dyslipidemia was more frequently associated with male gender.

CONCLUSIONS

Our results show that moderate-severe psoriasis is more common in men and suggests a differential gender distribution of some specific comorbidities in the setting of this disease.
