Upadacitinib for the management of bullous pemphigoid coexisting with psoriasis vulgaris: a case report and literature review

Both bullous pemphigoid (BP) and psoriasis are common immune-related dermatological conditions in clinical practice, but the co-occurrence of these two diseases is rare. Currently, there is no consensus on the long-term safe and effective treatment for patients with both BP and psoriasis. JAK inhibitors are emerging as targeted therapeutic drugs that act by inhibiting Janus kinase activity, regulating the JAK/STAT pathway, blocking the transduction pathway of key proinflammatory cytokines, and influencing T-cell differentiation. These cytokines upstream of the JAK/STAT pathway play a pivotal role in the pathogenesis of numerous inflammatory and autoimmune disorders. Upadacitinib, a second-generation JAK inhibitor with high selectivity, demonstrates promising potential.This case report aims to provide a description of the successful treatment of bullous pemphigoid (BP) and psoriasis vulgaris by using upadacitinib, highlighting significant clinical outcomes. Additionally, we aim to analyze the underlying mechanism of upadacitinib in treating these two comorbidities by reviewing relevant literature from both domestic and international sources. Based on our clinical observations, upadacitinib appears to be a promising and well-tolerated therapeutic option for patients with concurrent BP and psoriasis, offering valuable insights for developing appropriate treatment strategies in clinical practice.

Chinese herbal medicine bath therapy for psoriasis vulgaris using topical calcipotriol as the comparator: A systematic review with meta-analysis and association rule analysis

ETHNOPHARMACOLOGICAL RELEVANCE

Psoriasis is a chronic inflammatory skin disease. Vitamin D analogues are the first-line topical agents for the long-term management of psoriasis. Chinese herbal medicine (CHM) bath therapy is commonly employed for psoriasis. However, the effects and safety of CHM bath therapy for psoriasis vulgaris, using topical calcipotriol as the comparator, remain inconclusive. Furthermore, the combination of herbs, a distinctive feature of CHM, is essential for its therapeutic effects due to the individual and synergistic properties of the herbs involved.

AIM OF THE STUDY

The review was conducted to evaluate the effectiveness and safety of CHM bath therapy for psoriasis vulgaris, using calcipotriol as the comparator. Potential herbs and herb combinations of CHM bath therapy were also explored for further drug discovery.

MATERIALS AND METHODS

Nine databases were searched from inception until March 05, 2024. Randomised controlled trials (RCTs) investigating CHM bath therapy, using calcipotriol as the comparator, were included. Statistical analyses were performed using RevMan 5.4, Stata 12.0 and SPSS Clementine 12.0 software. The evidence certainty for outcomes was assessed using the approach proposed by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group. Moreover, association rule analysis on herbs identified in the systematic review was conducted to explore the potential herbs and herb combinations.

RESULTS

A total of 17 RCTs involving 1,379 participants were included in this systematic review. The findings of this review revealed that: 1) CHM bath therapy produced comparable effects to calcipotriol in reducing Psoriasis Area and Severity Index (PASI), Psoriasis Scalp Severity Index (PSSI), and itch visual analogue scale (VAS) at the end of the treatment phase; as well as exhibited a superior long-term effect than calcipotriol through decreasing relapse rates at the end of the follow-up phase; 2) CHM bath therapy showed an additional benefit when combined with calcipotriol in managing psoriasis vulgaris at the end of the treatment phase, in terms of PASI, PSSI, itch VAS, IL-17, IL-23, CD3+ and CD4+ T cells. The certainty of the evidence was rated as 'very low', 'low' or 'moderate' based on the GRADE assessment, considering some concerns or high risk of bias of included studies, substantial heterogeneity, and existing publication bias of some outcomes. Additionally, the proportions of participants reporting adverse events were similar in both groups. Association rule analysis of all included herbs identified 23 herb combinations including Prunus persica (L.) Batsch and Carthamus tinctorius L., as well as 11 frequently used herbs, such as Kochia scoparia (L.) Schrad., Dictamnus dasycarpus Turcz. And Sophora flavescens Ait.

CONCLUSIONS

The effects of CHM bath therapy were comparable with those of topical calcipotriol but demonstrated a longer-lasting effect. Combining CHM bath therapy with calcipotriol also provided an additional benefit for adult psoriasis vulgaris. However, the certainty of the evidence was downgraded due to the methodological limitations of included studies. To confirm the findings of this review, future investigations should involve double-blinded, placebo-controlled RCTs. Importantly, it appears worthwhile to consider further research for drug development utilising the identified herbs or herb combinations.

Population-based incidence of psoriasis vulgaris in Germany: analysis of national statutory insurance data from 65 million population

Information on the population-based incidence of psoriasis vulgaris was limited. This study was to provide a comprehensive understanding of the age-specific and sex-specific incidence of psoriasis vulgaris in Germany. The data were obtained in the context of a morbidity-based risk adjustment by statutory health insurance companies in Germany, comprising information regarding 65 million population. Psoriasis vulgaris diagnoses were made and coded according to the 10th edition of the International Statistical Classification of Diseases and Related Health Problems. Age-specific and sex-specific incidences were calculated using data from 2009 to 2011. There was a rise in the age- and sex-specific incidences of psoriasis vulgaris through midlife, reaching a peak at the age of 60 and subsequently declining for both genders. The peak incidence for men, at 130 cases per 100,000 person-years, slightly exceeded the peak incidence for women of 117 per 100,000 person-years. An increase in the overall incidence rate can also be observed over the course of the three-year period covered by the data. Considerable variations in the age- and sex-specific incidences of psoriasis vulgaris can be seen across the lifespan. Nevertheless, the overall age-standardized incidence for the German population was low compared to other European countries.

Treatment persistence of interleukin-17 inhibitor class drugs among patients with psoriasis in Japan: a retrospective database study

BACKGROUND AND OBJECTIVE

Real-world evidence on persistence of interleukin-17 inhibitors (IL-17i) as a drug class among Japanese patients with psoriasis is lacking. Hence, we aimed to describe persistence rates of IL-17is among patients with psoriasis including psoriasis vulgaris (PsO), psoriatic arthritis (PsA), and generalized pustular psoriasis (GPP) or erythrodermic psoriasis (EP) in Japan.

METHODS

We analyzed claims data from the Medical Data Vision database. Patients ≥15 years old with a psoriasis diagnosis and an IL-17i prescription between November 2016 and August 2020 were included and followed through August 2021. Persistence rates of the IL-17i class among patients with psoriasis and its subtypes (PsO, PsA, and GPP or EP), and persistence rates of ixekizumab, secukinumab, or brodalumab among patients with PsO or PsA were analyzed using Kaplan-Meier method. Analyses were conducted in the bio-naïve and bio-experienced subgroups.

RESULTS

The IL-17i class had >50% persistence rates up to 36 months among patients with psoriasis and its subtypes (PsO, PsA, and GPP or EP). 36-Month persistence rates for ixekizumab, secukinumab, and brodalumab were 46.2% to 57.7% in patients with PsO and 43.0% to 48.4% in patients with PsA. Across analyses, bio-naïve patients demonstrated similar or greater persistence rates than bio-experienced patients.

CONCLUSION

IL-17is' persistence rates over 36 months were >50% among patients with psoriasis and its subtypes (PsO, PsA, and GPP or EP) in Japan.

[Remission of recalcitrant generalized pustular psoriasis under interleukin-36 receptor inhibitor spesolimab]

Generalized pustular psoriasis (GPP) is often a life-threatening disease which, in contrast to psoriasis vulgaris, is associated with the formation of sterile pustules on the skin. Until recently, there was no approved treatment in Europe, so that drugs used for psoriasis vulgaris were also frequently used for GPP. However, new studies showed that, in GPP, mutation of the interleukin-36 receptor often leads to increased inflammation and corresponding disease activity. We report a case of GPP with complete remission after two doses of spesolimab, a new interleukin-36 receptor antibody.

Assessment of cytochrome P450 1A1 gene polymorphism and vitamin A serum level in psoriasis vulgaris

Psoriasis is characterized by cutaneous hyperproliferation, secondary to immune system dysregulation. Vitamin A regulates the immune response and sustains epithelial tissue hemostasis. The CYP1A1 gene, has many biological actions, including vitamin A metabolism. To evaluate CYP1A1 gene polymorphism and serum vitamin A level in patients with psoriasis vulgaris, a case-control study involving two groups was conducted: group 1 (45 patients with psoriasis vulgaris) served as the cased group and group 2 (45 healthy participants who were sex and age matched) acted as the control group. CYP1A1 (rs1048943) gene polymorphism and vitamin A serum level were assessed by TaqMan allelic discrimination (PCR) and ELISA, respectively. AG genotype was present only in cases (22.2%), while AA genotype was present in all controls (P=.001). Vitamin A levels were lower in cases than in controls (32.0 ± 7.41 vs. 46.2 ± 15.7 μg/ml, respectively) (P<.001). AG genotype was associated with a lower vitamin A level (P=.001). The detected genotype difference between psoriasis patients and controls, which was associated with a lower serum vitamin A level and was also lower in more severe cases, suggests a role of the CYP1A1 gene and vitamin A in disease pathogenesis and prognosis.

New-Onset Guttate Psoriasis: A Long-Term Follow-Up Study

BACKGROUND

Guttate psoriasis (GP), a distinct variant of psoriasis, is more common in children and adolescents. The long-term course of these patients has sparsely been examined, with few studies reporting the rates of relapse, persistence, and further development of the psoriasis vulgaris phenotype.

OBJECTIVES

The objective of this study was to characterize the long-term outcomes of new-onset GP and elucidate the potential factors associated with a persistent disease course.

METHODS

This was a retrospective cohort study. Patients diagnosed with new-onset GP between 2009 and 2020 with a follow-up period of at least 1 year, were enrolled. The examinees were evaluated by dermatologists. Detailed data retrieved from the examinees' medical files included demographics, disease characteristics, treatment, and comorbidities. A structured telephone questionnaire was used to determine the current psoriasis status: type, severity, and extent. At the end of follow-up, patients with a persistent disease course, defined as having lesions at least a year after disease onset, were compared with patients in complete remission without further psoriasis symptoms.

RESULTS

A total of 120 patients (mean age 28.8 years [±15.2], 58.3% women) with new-onset GP flare were identified. At the end of follow-up period (mean 6.2 years [±3.1]), 49.1% (n = 59) of the patients reported active persistent psoriasis. A switch to the psoriasis vulgaris phenotype occurred in 17.5% (n = 21) of the study cohort. Persistent psoriasis was associated with male sex (OR = 2.1, p < 0.05), multiple disease flares (>3; OR = 9.1, p < 0.001), switch to the vulgaris phenotype (OR = 4.16, p < 0.001), and palmoplantar involvement (OR = 5.2, p < 0.01).

CONCLUSION

A persistent disease course is common among patients with new-onset GP, with most retaining their guttate phenotype throughout the disease course. Persistency was associated with male sex, multiple GP flares, switching to the vulgaris phenotype, and palmoplantar involvement.

Correlation of catecholamine content and clinical influencing factors in depression among psoriasis patients: a case-control study

Objective

Our study sought to investigate the clinical influencing factors of psoriasis patients with depression, and analyze whether the content of monoamine neurotransmitters in plasma was correlated with depression incidence among psoriasis patients.

Methods

Ninety patients with psoriasis and 40 healthy volunteers (aged from18 to 60) were recruited and interviewed with a piloted questionnaire in both groups to obtain relevant information. The catecholamine in plasma from the two groups was analyzed by radioimmunoassay. The data were analyzed by SPSS statistical software.

Results

The mean Hamilton Depression Scale (HAMD) and mean Athens Insomnia Scale (AIS) scores of the psoriasis patients were higher than the control group. Dopamine content in the plasma was lower (comparing psoriasis patients without depression and the control group, and was negatively correlated with HAMD, AIS, and Psoriasis Area and Severity Index (PASI) scores in the psoriasis patients with depression. There was no significant difference in the epinephrine and norepinephrine contents in all groups. PASI scores were positively correlated with HAMD scores in psoriasis patients. The low dopamine content, Dermatology Life Quality Index, and high PASI scores were the risk factors for depression among the psoriasis patients.

Conclusion

Psoriasis patients have a significantly higher risk of depression than healthy people, and higher PASI scores were linked to a higher incidence of depression. The dopamine levels of patients were influenced by both psoriasis and depression. The risk factors for depression in psoriasis patients are low dopamine levels in the plasma, severe skin lesions, and lower quality of life.

The Association Between Forkhead Box Class O3A Gene Polymorphism and Psoriasis and Its Relationship with Psoriasis Severity

BACKGROUND

Psoriasis vulgaris is a chronic, relapsing, inflammatory disorder marked by an intensified immune response. The role of immunogenetics in psoriasis is still poorly understood; however, experts agree that its expression depends on proinflammatory cytokines.Forkhead box class O3A (FOXO3a), a transcription factor, plays a crucial role in intercellular regulation, oxidative stress, deoxyribonucleic acid (DNA) repair, and cell death.

OBJECTIVE

The objective of this study was to investigate the role of FOXO3a genetic polymorphism as a risk factor for psoriasis vulgaris and assess its possible relationship with disease severity.

METHODS

A comparative case-control study included 53 patients with psoriasis and 41 matched healthy controls. We measured serum FOXO3a levels and used the PCR-RFLEP technique to detect FOXO3a genetic polymorphism (rs13217795) in both groups.

RESULTS

Our results revealed significantly higher serum FOXO3a levels in the psoriasis group compared to the control group (p≤0.001). Serum FOXO3a levels were significantly higher in patients with severe psoriasis than in those with mild-to-moderate disease. FOXO3a genotypes found homozygous mutant genotype (TT) was substantially more frequent in the psoriasis group than in the control group. Furthermore, the T allele was more frequent in the psoriasis group than in the control group.

CONCLUSION

The study indicates that rs13217795 polymorphism of the FOXO3a gene is strongly associated with susceptibility to psoriasis. Also, the serum level of FOXO3a is significantly higher in patients with severe psoriasis, compared to patients with mild-to-moderate psoriasis. This finding could be an area of future targeted therapy.

Effect of Traditional Chinese Medicine on Psoriasis Vulgaris: A Meta-Analysis and Systematic Review

BACKGROUND

Psoriasis is a chronic, inflammatory autoimmune skin disease that affects 2-3% of the world's population. Lesions are mainly found on the limbs, trunk, and scalp, but may also affect other parts of the body, and the cause is not yet known. The chronic and relapsing nature of psoriasis makes it one of the most complex and important diseases in current dermatology research.

METHODS

The search was conducted using PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Internet, Wanfang Data, VIP journals database, and Chinese biomedical literature database (CBM). The retrieval time limit was from the establishment of the database to January 2021. The quality of the selected literature was evaluated, and ReView Manager 5.3 was used for meta-analysis after randomized controlled trials were filtered.

RESULTS

Finally, 16 randomized controlled trials involving 1,967 patients were included. The total effective rate (OR = 3.68, 95% CI [2.73, 4.95], p < 0.00001), cure rate (OR = 2.01, 95% CI [1.62, 2.49], p < 0.00001), and PASI score (OR = -1.83, 95% CI [-2.39, -1.26], p < 0.00001) of the traditional Chinese medicine (TCM) were superior to the Diyin tablet.

CONCLUSION

In the treatment of psoriasis, TCM shows higher efficacy than the Diyin tablet. However, due to the limitations of the included literature, we still need more double-blind, placebo-controlled trials with large samples and multiple centers to provide high-quality clinical evidence.

[Uncommon presentation of psoriasis vulgaris in an 11-year-old patient]

Die Psoriasis vulgaris tritt mit einer Prävalenz von bis zu 2 % im Kindes- und Jugendalter auf. Größtenteils wird die Diagnose klinisch gestellt. Wir berichten über einen pädiatrischen Patienten, welcher uns aufgrund der für eine Psoriasis vulgaris eher untypischen Lokalisation vor eine diagnostische Herausforderung stellte.

Reduction in Tumor Lesions and Exacerbation of Psoriatic Rash after Septic Shock in a Patient with Extramammary Paget's Disease

We present a case of extramammary Paget's disease with bilateral inguinal lymph node metastasis treated by monthly docetaxel chemotherapy. He has also well-controlled psoriasis vulgaris for 20 years. One day after completing monthly chemotherapy, cellulitis by Group G Streptococcus occurred on both legs, resulting in septic shock and disseminated intravascular coagulation. During the infection, the tumor nodule volume and the exudate from the tumor decreased, and tumor markers carcinoembryonic antigen and cancer antigen 19-9 showed low values. Simultaneously, the psoriatic eruption reoccurred. We proposed that cytokine storm including tumor necrosis factor-alpha (TNF-α) during sepsis might have suppressed tumor lesions, and also TNF-α-dependent psoriatic rash appeared temporarily on his body.

[Erythrodermic psoriasis after COVID-19]

Wir präsentieren einen klinischen Fall eines Patienten mit akut exazerbierter erythrodermer Plaquepsoriasis nach einer symptomatischen Infektion mit SARS-CoV‑2. Es sind bereits unterschiedliche Faktoren bekannt, die zu einer Exazerbation der Psoriasis führen können wie Medikamente oder Infektionen mit z. B. Streptokokken. Ein Zusammenhang zwischen Psoriasis und einer Infektion mit dem neuartigen Coronavirus SARS-CoV‑2 wurde v. a. in Fallberichten beschrieben, in denen eine medikamentöse Behandlung mit z. B. Hydroxychloroquin erfolgt war, ein bekannter Trigger der Psoriasis. In der Folge gab es auch einzelne Beschreibungen einer Exazerbation nach COVID-19 ohne medikamentösen Trigger, teils auch als pustulöse Psoriasisform. Unser Artikel zeigt erstmals einen Fall einer Psoriasiserythrodermie getriggert durch eine COVID-19-Erkrankung ohne offensichtlich zusätzlich medikamentösen Auslöser.

RNA-seq reveal RNA binding protein GNL3 as a key mediator in the development of psoriasis vulgaris by regulating the IL23/IL17 axis

BACKGROUND

Psoriasis is a systemic chronic inflammatory skin disorder that was prone to recurrence. The RNA binding protein GNL3 has an important function in maintaining the proliferative ability of stem cells, and its overexpression leads to apoptosis. GNL3 is expressed in the epidermis, however, its regulatory mechanism in psoriasis vulgaris is still poorly understood.

OBJECTIVE

To identify the role of GNL3 in the pathogenesis of psoriasis vulgaris.

MATERIALS AND METHODS

RNA-seq was performed to obtain the data of genes' expression and splicing events in Hela cells after shGNL3 and shCtrl was transferred. High quality results of differentially expressed genes (DEGs) and alternative splicing events (ASEs) were further attained by quality control and analysis. Through the functional enrichment analysis of DEGs and ASEs, the regulating effect of GNL3 was discussed, and the hypothesis was further confirmed in HaCat cells and psoriasis lesions.

RESULTS

The mRNA expression of IL23A in Hela cells was upregulated in GNL3 knockdown, and the ratio of ASE occurred in TNFAIP3 was increased. However, in HaCaT cells, the mRNA expression level of IL23A was downregulated in GNL3 knockdown, and the ratio of ASE of TNFAIP3 was decreased. Additionally, the results obtained in HaCaT cells was further validated in the lesional psoriatic skin.

CONCLUSION

GNL3 takes an important part in the development of psoriasis vulgaris by regulating the IL23/IL17 axis, which may serve as the basis of effective targeted treatment in future.

Circulating microRNA profile unveils mechanisms of action of acitretin for psoriasis vulgaris

Psoriasis vulgaris is a common chronic and recurrent inflammatory skin disease. In clinical practice, acitretin is the first-line treatment drug for psoriasis vulgaris. MicroRNAs (miRNAs) play a vital role in the initiation and development of psoriasis vulgaris. However few studies focused on the mechanisms of acitretin in the treatment of psoriasis vulgaris from the perspective of miRNAs. Here, the expression profiles of circulating miRNAs in the plasma of 12 patients with psoriasis vulgaris before and after acitretin treatment were sequenced. Three miRNAs (miR-146a-5p, miR-122-5p and miR-21-5p) were identified using expression pattern analysis, and the levels were significantly decreased after acitretin treatment (P< 0.001). Receiver operating characteristic (ROC) analyses indicated that the three miRNAs have the potential to be utilized as molecular markers to evaluate the therapeutic effect of acitretin, and the values of the area under the curve (AUC) were 0.825, 0.831, and 0.796, respectively. In addition, we predicted target genes of the three miRNAs and performed signaling pathway enrichment analyses. The results demonstrated that the target genes were mainly involved in the MAPK, JAK-STAT, and NF-κB signaling pathways, which were further validated through in vitro experiments. In conclusion, acitretin can suppress miRNA-mediated MAPK, JAK-STAT, and NF-κB signaling pathways by decreasing miRNAs expression, thereby inhibiting the proliferation and inflammatory response of keratinocytes.

Comparison of PSORI-CM01 granules and Yinxieling tablets for patients with chronic plaque psoriasis: a pilot study for a randomized, double-blinded, double-dummy, multicentre trial

BACKGROUND

To compare the efficacy and safety of PSORI-CM01 granules with Yinxieling tablets in patients with chronic plaque psoriasis (CPP), we plan to conduct a multicentre, randomized, double-blinded, double-dummy, controlled trial. This pilot study was conducted to determine the feasibility and the potential of the protocol for the full-scale randomized controlled trial (RCT).

METHODS

This pilot study was conducted in three centers, and compared PSORI-CM01 granules with Yinxieling tablets in patients with CPP during a 12-week treatment and 3-month follow-up period. The primary efficacy endpoint was the decrease of the psoriasis area severity index (PASI) at week 12. The secondary outcome measures included reduction rates of PASI, pruritus scores on the Visual Analogue Scale (VAS), body surface area (BSA), and the Dermatology Life Quality Index (DLQI). Safety was assessed via the incidence of adverse events (AEs) in each treatment group.

RESULTS

A total of 211 patients were screened, and 63 subjects who met the inclusion criteria were randomised to PSORI-CM01 granule group (N=31) or Yinxieling tablets group (N=32) while 39 subjects finished the study. The primary outcome measure showed a mean decrease of PASI of 2.03 in the PSORICM01 group compared to 0.89 in the Yinxieling group at week 12. Except for the VAS score (t=-2.261, P=0.027), the secondary outcomes showed no significant improvement from baseline in both groups at week 12. No safety or tolerability concerns related to the drugs were observed in either group.

CONCLUSIONS

This pilot study showed that the RCT is feasible for randomization, patient recruitment, and assessment. Major strategies are necessary to reduce the patient dropout rate before conducting the full RCT. In this pilot study, the PSORI-CM01 granule exhibited greater potential for development compared to its original formula (Yinxieling tablets) for the treatment of CPP.

Association between Vaspin rs2236242 Gene Polymorphism and Psoriasis Vulgaris

BACKGROUND

Psoriasis known as a chronic inflammatory skin disease is accompanied by metabolic disorders such as obesity, diabetes, and dyslipidemia. Vaspin (a serine protease inhibitor derived from visceral adipose tissue) is a newly identified adipokine and a link between inflammation and obesity has been reported. We aimed to determine whether vaspin gene polymorphism is associated with the development and/or clinical features of psoriasis vulgaris.

METHODS

Our study group consisted of 96 psoriasis vulgaris patients and 100 matched controls. Vaspin rs2236242 gene was genotyped using PCR.

RESULTS

The vaspin genotypes showed a meaningful difference between psoriasis and control groups (p = 0.02). The frequency of the vaspin rs2236242 TT genotype was lower in psoriasis patients than in control participants (p < 0.05). The TA genotype was associated with a 2.38-fold increased risk of psoriasis compared to the TT genotype (p = 0.007, odds ratio: 2.38; 95% confidence interval: 1.25-4.55), but not the AA genotype. All subjects were the Turkish population, the study in other populations is needed and the sample size was small in number.

CONCLUSION

Our study demonstrated that vaspin rs2236242 polymorphism is related to psoriasis in the Turkish population. Polymorphisms of the vaspin gene might serve as diagnostic biomarkers of psoriasis.

PSO-LONG: Design of a Novel, 12-Month Clinical Trial of Topical, Proactive Maintenance with Twice-Weekly Cal/BD Foam in Psoriasis

Background

Psoriasis vulgaris is commonly treated with topical corticosteroids and vitamin D analogues. Although potent and super-potent topical corticosteroids are very effective at clearing psoriasis, with short-term reactive treatment durations, symptoms usually recur after treatment discontinuation, necessitating long-term disease management strategies. A foam formulation of calcipotriol and betamethasone dipropionate (Cal/BD foam), consisting of calcipotriol 50 μg/g and betamethasone dipropionate 0.5 mg/g, is approved for the daily treatment of psoriasis for up to 4 weeks. Here, we describe a clinical trial protocol for evaluating the long-term safety and efficacy of twice-weekly Cal/BD foam as a proactive topical maintenance therapy for plaque psoriasis for up to 52 weeks.

Objective

The aim of this trial was to evaluate the safety and efficacy of Cal/BD foam when applied twice weekly for up to 52 weeks as proactive maintenance therapy, with the goal of preventing or delaying disease relapse as long as possible while minimizing adverse effects.

Methods

Once-daily Cal/BD foam treatment responders from an initial 4-week open-label period were randomized to receive Cal/BD foam or foam vehicle applied to previously cleared plaques twice weekly for up to 52 weeks. In case of relapse, affected subjects in either group received rescue therapy with once-daily Cal/BD foam for 4 weeks on active areas. Thus, the trial (NCT02899962) compared the long-term use of Cal/BD foam in a proactive approach with a conventional, reactive approach.

Planned Outcomes

Efficacy endpoints included the time to first relapse, the number of relapse-free days, and the number of relapses during the maintenance phase. Safety assessments included adverse events, incidence of rebound, local safety and tolerability scores, and effects on calcium metabolism and hypothalamic–pituitary–adrenal axis function.

Trial registration

ClinicalTrials.gov identifier, NCT02899962.

Detection of subclinical skin manifestation in patients with psoriasis and psoriatic arthritis by fluorescence optical imaging

OBJECTIVES

To investigate the frequency of subclinical skin inflammation in both hands by fluorescence optical imaging (FOI) in patients with psoriasis/psoriatic arthritis (Pso/PsA) vs. rheumatoid arthritis (RA) and healthy individuals, and to correlate these findings with cardiovascular (CV) risk factors.

PATIENTS AND METHODS

The FOI scans were analyzed retrospectively to detect clinically invisible skin enhancement (0-3 scale) in both hands without relationship to underlying joints or blood vessels. We further characterized the FOI patterns and sorted the scans into groups based on the assumed diagnosis (Pso/PsA, RA, and healthy controls), which was compared with the physician's diagnosis. Furthermore, the associations between CV risk factors and imaging findings were investigated by regression analyses.

RESULTS

We included FOI scans of patients with Pso/PsA (n = 80), RA (n = 78), and healthy controls (n = 25). Subclinical skin enhancement on the back of their hands was more common in Pso/PsA (72.5%) than in RA patients (20.5%) and healthy individuals (28.0%) (p < 0.001). Based on the FOI pattern, the majority of patients with Pso/PsA (72.5%), RA (76.9%), and healthy controls (68.0%) were classified correctly using the physician-based diagnosis as reference (overall agreement of 74%, kappa = 0.57). No CV risk factors except body weight (kg) were associated with subclinical skin enhancement (OR 1.04, 95% CI 1.02-1.06; p < 0.001).

CONCLUSION

Subclinical subdermal skin inflammation was common in Pso/PsA patients using FOI. Based on the FOI pattern, most patients with Pso/PsA and were classified with the correct diagnosis. We demonstrated an important influence of the body weight on our FOI results. FOI may be a helpful novel tool to study microcirculation in rheumatic diseases with skin involvement.

Quantitative analysis of differentially expressed proteins in psoriasis vulgaris using tandem mass tags and parallel reaction monitoring

Background

Psoriasis vulgaris (PV) is a chronic autoimmune inflammatory disease with epidermal hyperkeratosis and parakeratosis.

Methods

The study was to elucidate the pathogenesis of PV by quantitative proteomic analysis of skin lesion biopsies of PV and healthy tissues with tandem mass tags (TMTs) coupled with liquid chromatography–mass spectrometry (LC–MS)/MS.

Results

A total of 4562 differentially expressed proteins (DEPs) between PV lesional tissues (n = 11) and healthy tissues (n = 11) were identified, of which 299 were upregulated and 206 were downregulated using |fold change| > 1.3 as the cutoff threshold. The Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that the DEPs were mainly enriched in the activation of immune cells (drug metabolism pathway, NOD-like pathway, and IL-17 pathway), cell proliferation (ribosomal pathway, DNA replication pathway, and base replication pathway), metabolism-related pathways (fatty acid biosynthesis and metabolism, PPAR pathway, glycerophospholipid metabolism, and cortisol synthesis and breakdown), and glandular secretion (saliva secretion, gastric acid secretion, and pancreatic fluid secretion). Thirteen DEPs that were relatively highly expressed in the drug metabolism pathway were validated with parallel reaction monitoring (PRM), of which MPO, TYMP, IMPDH2, GSTM4, and ALDH3A1 were highly expressed in PV, whereas CES1, MAOB, MGST1, and GSTT1 were less expressed in PV.

Conclusions

These findings confirmed that these proteins participate in the drug metabolism-other enzyme pathways and play crucial roles in the activation and proliferation of immune cells in the pathogenesis of PV.

The immune status of patients with psoriasis vulgaris of blood-stasis syndrome and blood-dryness syndrome: a qualitative evidence synthesis

BACKGROUND

Chinese medicine (CM) classifies psoriasis vulgaris into three syndromes: blood-heat syndrome (BHS), blood-stasis syndrome (BSS), and blood-dryness syndrome (BDS). The levels of several immunological serum markers in BHS have been established. We aimed to investigate the immune status of patients with psoriasis vulgaris of BSS and BDS.

METHODS

Seven databases were searched, covering nearly 40 years. Fifteen studies including 957 individuals (386 patients with psoriasis vulgaris of BSS, 233 patients with BDS, and 338 healthy controls) were identified. Differences in interleukin (IL) levels between subjects and controls were pooled as mean differences (MDs) with 95% confidence intervals (CI) using a random-effects model.

RESULTS

For BSS, interferon (IFN)-γ (MD 3.85, 95% CI: 1.27 to 6.44), tumor necrosis factor (TNF)-α (MD 1.71, 95% CI: 0.70 to 2.72), IL-4 (MD 7.66, 95% CI: 4.67 to 10.65), IL-17 (MD 5.06, 95% CI: 0.28 to 9.85), IL-6 (MD 99.34, 95% CI: 45.84 to 152.84), and IL-22 (43.88, 95% CI: 28.17 to 59.59) levels were significantly higher in patients than in controls, while pooled IL-10 levels were lower in patients (MD -10.33, 95% CI: -12.03 to -8.63). The MD in IL-8 levels between cases and controls was not significant. Subjects with BDS showed higher levels of IFN-γ (MD 2.33, 95% CI: 0.22 to 4.45), TNF-α (MD 2.33, 95% CI: 1.26 to 3.40), and IL-23 (MD 46.18, 95% CI: -7.60 to 99.97) and lower levels of IL-4 levels (MD -2.47, 95% CI: -4.78 to -0.15) than did controls. The MDs in IL-17, IL-6, and IL-8 levels were not statistically significant.

CONCLUSIONS

Our pooled analysis suggests that the levels of several ILs are specifically altered in BSS and BDS. Larger, well designed, controlled studies are needed to confirm these results and fully clarify these effects.

Exacerbation of psoriasis vulgaris by sorafenib treatment for hepatocellular carcinoma

We treated a 66-year-old Japanese male with unresectable hepatocellular carcinoma (u-HCC) for multiple (>5) liver tumors (maximum 2.6 cm in size, Child-Pugh B score 7) in September 2018. The patient had a history of psoriasis vulgaris and sorafenib (SOR) was introduced (800 mg/day) because of transcatheter arterial chemoembolization (TACE) refractoriness. However, psoriasis vulgaris exacerbation and a high fever were observed 2 weeks later, and the patient was admitted, after which improvement of psoriasis vulgaris was obtained with external medicine administration and SOR intake discontinuation. Few reports have noted exacerbation of psoriasis vulgaris caused by SOR treatment.

Patient and Physician Satisfaction with Calcipotriol and Betamethasone Dipropionate Aerosol Foam in the Treatment of Plaque Psoriasis on the Body

BACKGROUND AND OBJECTIVE

Calcipotriol and betamethasone dipropionate (Cal/BD) aerosol foam is more effective in the treatment of plaque psoriasis than earlier formulations incorporating this combination of active ingredients. The aim of this study was to evaluate patient and physician satisfaction with Cal/BD aerosol foam in the treatment of plaque psoriasis on the body.

MATERIAL AND METHODS

Retrospective observational study of 446 patients with plaque psoriasis affecting no more than 30% of the body surface area who had received treatment with Cal/BD aerosol foam for 4 weeks. The patients rated their satisfaction with the treatment using the TSQM-9 (Treatment Satisfaction Questionnaire for Medication) and the physicians on a 5-point Likert scale.

RESULTS

Patients were highly satisfied with Cal/BD aerosol in terms of its ability to treat their condition (84%), relieve their symptoms (84.4%), and act rapidly (82.8%). With respect to convenience, the patients gave high ratings to ease of use (91.8%), ease of planning (93.9%), and ease of following instructions (89.9%). Global satisfaction was also high, with 85% of patients expressing that they were satisfied, very satisfied, or extremely satisfied with the treatment. Of the physicians, 85.7% stated that they were quite or very satisfied with the treatment.

CONCLUSION

Both patients and physicians expressed high satisfaction with the use of Cal/BD aerosol foam for the treatment of plaque psoriasis on the body.

Skin tissue expression and serum level of thymic stromal lymphopoietin in patients with psoriasis vulgaris

Thymic stromal lymphopoietin (TSLP) is known to be associated with allergic diseases. It is also suggested that TSLP has a role in autoimmune diseases such as psoriasis; however, the associated pathways remain unknown. There is currently little information on TSLP in psoriasis vulgaris. We investigated TSLP expressions on lesional and non-lesional skin of psoriasis vulgaris patients using reverse transcription- polymerase chain reaction. TSLP level was also investigated in serum from psoriasis vulgaris patients compared to healthy control using enzyme-linked immunosorbent assay. TSLP expression was higher in lesional skin (1.90) compared to non-lesional skin (1.76); however, the difference was not statistically significant (P>0.05). TSLP serum levels were significantly higher in psoriasis patients (287.40 pg/dL) as compared to controls (114.70 pg/dL) (P<0.05). This study concluded that TSLP levels in the serum of psoriasis vulgaris patients are higher than controls. TSLP was also found in keratinocyte of psoriasis patients, the expression was higher in the lesional compared to non-lesional skin; however, this difference is statistically insignificant. These findings suggest that TSLP may play a role in the pathogenesis of psoriasis vulgaris, but its exact role remains unclear.

Alopecia Diffusa while Using Interleukin-17 Inhibitors against Psoriasis Vulgaris

We report two cases of alopecia diffusa during the treatment of psoriasis vulgaris with interleukin (IL)-17 inhibitors. Psoriasis is one of the most common immune-mediated chronic skin diseases, strongly associated with IL-17A. Clinically, the monoclonal antibodies to IL-17A or its receptor, IL-17R, show a dramatic effect against psoriasis. Alopecia is also an IL-17-mediated autoimmune disease, and IL-17 inhibitors have been expected to be the gold standard for the treatment of alopecia; therefore, the complication of alopecia while using IL-17 may be regarded as an unexpected "paradoxical reaction." T helper (Th)17 cells are not cytotoxic enough by themselves to undermine the hair follicle under normal circumstances, they need the coexistence of CD8+ cytotoxic Th1 cells. Th17 cells may be the initiator of the damage of the hair follicle, but CD8 T cells or more powerful Th1 cells are required as followers. The Th17/Th1 axis might convert into a Th1-dominant immune status using IL-17 inhibitors, and the destruction of the hair follicle might result in alopecia. An accumulation of cases is to be expected.

Correlation between Serum Brain-Derived Neurotrophic Factor Level and Depression Severity in Psoriasis Vulgaris Patients

BACKGROUND

Psoriasis vulgaris is a chronic inflammatory skin disorder that can lead to depression. There is a similarity in neurotrophic substance in the pathogenesis of psoriasis and depression; it's called brain-derived neurotrophic factor (BDNF). BDNF level imbalance potentially affects the severity of psoriasis and depression.

AIM

This study aims to know the correlation between serum BDNF level and depression severity in psoriasis vulgaris patient and also the correlation between serum BDNF level and psoriasis vulgaris severity.

METHODS

This is an analytical cross-sectional study that 23 psoriasis vulgaris patients participated. All participants have performed serum BDNF level examination with enzyme-linked immunosorbent assay (ELISA). Depression severity assessed with Beck depression inventory-II (BDI-II) and psoriasis severity assessed with psoriasis area and severity index. Correlation between all variables was analysed with Spearman's correlation test.

RESULTS

Serum BDNF level and depression severity are a strongly negative correlation in psoriasis vulgaris patients (r = -0.667 with significant value p = 0.001). There is a moderate negative correlation between serum BDNF level with psoriasis vulgaris severity (r = -0.595 with significant value p = 0.003).

CONCLUSION

In psoriasis vulgaris patients, a low level of serum BDNF may increase depression severity and psoriasis vulgaris severity.

Successful Psoriasis Treatment Using NB-UVB with Methotrexate: The Vietnamese Experience

AIM

To compare the effectiveness of narrowband ultraviolet B (NBUVB) and oral methotrexate (MTX) to oral MTX alone in Vietnamese psoriasis patients, from May 2016 to May 2018.

METHODS

We conducted a non-randomized trial on 70 patients with plaque-type psoriasis of moderate to severe. Thirty-five patients apply NBUVB once/day in 5 days/week for 4 weeks plus oral MTX 7.5 mg/week and 35 patients oral MTX 7.5 mg/week and both two groups treatment for 3 months. The extent of the lesion was assessed by the Psoriasis Area and Severity Index (PASI).

RESULTS

The proportion of decreasing PASI was comparable (68.49% in NBUVB and MTX versus 57.62% in MTX alone); p < 0.05. Inside, good 28.58%, moderate 68.57% and poor 2.85% in NBUVB and MTX better than good 2.85%, moderate 71.4% and poor 25.72% in MTX alone; p < 0.05. The recurrence rate after 24 months of the NBUVB and MTX group (42.9%) was lower than the MTX alone group (71.4%); p < 0.05.

CONCLUSION

NBUVB and oral MTX have affected treatment with chronic plaque psoriasis better than oral MTX alone.

Thuvaraka rasayana regimen in Psoriasis vulgaris - A case report

Psoriasis is one among the wide-spreading, chronic, frequently recurring diseases of the skin. Its world prevalence varies between 0.09% and 11.4% in 2013 which reported in 2006 as in between 0.5% and 4.6%. In Ayurveda, the description of Kushta-roga viz. Vata-Kaphaja kushta finds similarity with psoriasis. The common sites of occurrence of psoriasis are scalp, elbow, knee, earlobes and sole which are also considered as the location of Vata and Kapha. The science of Ayurveda has anecdotal accounts of success in the management of psoriasis in the actual clinical practice even though it lacks the evidence-based medical dermatology research data. It observed that the physicians adopt several treatment protocols for the cure of this disease in clinical practice, which was not rigorously evaluating in research settings. This paper/report is one of on the 'Thuvaraka rasayana' is one such component that could improve treatment outcomes in Psoriasis. A pre and post test case report selected of a 36-year-old lady patient who diagnosed as having stable psoriasis vulgaris for last seven years. She was administered with internal and external therapies along with Shodhana therapies (bio-cleansing procedures) and then followed by intake of Thuvaraka rasayana. The total duration of the treatment was 43 days, and the Study subject assessed before treatment, after treatment and on follow-up for improvement using PASI scoring, and histo-pathological study. All the symptoms observed in the beginning were found considerably reduced, and the severity also found mild. On the follow-up, it concluded that the lesions disappeared completely and the skin set back to its normal texture. Even though psoriasis is an autoimmune disease where recurrence rate found more Shodhana therapy and Thuvaraka rasayana have a definite role.

Successful Certolizumab Pegol Treatment of Chronic Anterior Uveitis Associated with Psoriasis Vulgaris

This report presents details on a 45-year-old male Japanese patient with chronic and refractory anterior uveitis associated with psoriasis vulgaris who was administered certolizumab pegol (CZP), which is an anti-tumor necrosis factor alpha (TNF-α) monoclonal antibody. Although CZP has only been formally approved for rheumatoid arthritis treatment in Japan, a clinical trial allowed us to assess CZP effectiveness in this patient. The grade 3+ anterior chamber inflammation (for both the cells and flare) observed at baseline improved to grade 0 at 3 months post-treatment. Dermatologically, the psoriasis area severity index (PASI) score was 25.4, while the body surface area (BSA) was 88% at baseline. At 3 months after treatment, the scores improved to 2.8 for PASI and less than 1% for BSA. After the treatment, remission has lasted for at least 9 months. No adverse events were seen during the CZP treatment. These findings suggest that CZP could be an effective therapeutic alternative in some refractory anterior uveitis patients with psoriasis vulgaris.

HLA-C*06:02-independent, gender-related association of PSORS1C3 and PSORS1C1/CDSN single-nucleotide polymorphisms with risk and severity of psoriasis

Psoriasis vulgaris (PsV) is a common, chronic skin disease with a complex genetic and environmental etiology. We investigated, in 461 psoriatic patients and 454 healthy controls, the associations with psoriasis of four single-nucleotide polymorphisms (SNPs) from the psoriasis susceptibility 1 (PSORS1) interval: rs1062470 (PSORS1C1/CDSN), rs887466 (PSORS1C3), rs2894207 and rs10484554 (LOC105375015). The minor alleles of three SNPs (rs1062470A, rs2894207C and rs10484554T) strongly increased the disease risk (OR = 2.17, p < 0.0001; OR = 2.33, p < 0.0001 and OR = 2.68, p < 0.0001, respectively), whereas the minor A allele of rs887466 exerted a protective effect (OR = 0.73, p = 0.001). The strength of association for SNPs was the highest in patients with very early onset psoriasis (≤ 20 years), while in late onset psoriasis (> 40 years) the association was the weakest. The haplotype rs1062470A/rs887466G/rs2894207C/rs10484554T highly significantly increased the disease risk (OR = 3.58, p = 8.0e-027), while the haplotypes rs1062470G/rs887466A/rs2894207T/rs10484554C and rs1062470G/rs887466G/rs2894207T/rs10484554C were strongly protective (OR = 0.65, p = 0.002 and OR = 0.55, p = 2.4e-009, respectively). Additionally, we showed a HLA-C*06:02-independent gender-related effect of the rs887466A allele which was protective against psoriasis in males (OR = 0.61, p = 9.2e-005), but not in females (p = 0.66). We also demonstrated a correlation of PASI score value with rs1062470 genotype, and again only in male patients (p = 0.006) and HLA-C*06:02-independent. Our results show, for the first time, the male-only associations of the PSORS1C3 gene with psoriasis risk and of the PSORS1C1/CDSN gene with severity of disease. However, the age dependent associations need to be validated in larger sample sizes as well as in other populations.

MiR-200a expression in CD4+ T cells correlates with the expression of Th17/Treg cells and relevant cytokines in psoriasis vulgaris: A case control study

The main aim of this study is to investigate the underlying relationship shared between microRNA-200a (miR-200a) and its link to concentrations of Th17 and Treg cells, mRNA expressions of their specific transcription factors retinoic acid-related orphan receptor γt (RORγt) and head box protein 3 (FOXP3) and relevant cytokines in patients with psoriasis vulgaris (PV). A total of 189 patients previously diagnosed with PV were selected as the experimental group, whilst 109 healthy individuals as the control group. According to the psoriasis area and severity index (PASI), subjects in the experimental group were assigned into the severe group (95 cases) and the moderate group (94 cases). CD4⁺ T and Th17/Treg cells were extracted. MiR-200a expression and RORγt and FoxP3 mRNA expressions were detected by qRT-PCR. Concentrations of Th17 and Treg cells were measured via flow cytometry. ELISA was conducted for serum IL-17, IL-23 and TGF-β levels. Correlation analysis was completed in accordance with the Pearson method. Compared with the moderate group, higher miR-200a expression, RORγt mRNA expression, percentage of Th17, Th17/Treg ratio and levels of IL-17 and IL-23 exhibited in the severe group, whilst FoxP3 mRNA expression and, percentage of Treg as well as TGF-β were lower. A same trend displayed when comparing the moderate group to the control group. We found that miR-200a expression, percentage of Th17, Th17/Treg ratio, IL-17 and IL-23 levels and RORγt mRNA expression are positively correlated with PASI grade, while the percentage of Treg, TGF-β level and FoxP3 mRNA expression are negatively correlated with PASI grade. The results also displayed that the percentage of Th17, Th17/Treg ratio, IL-17 and IL-23 levels and RORγt mRNA expression are positively correlated with miR-200a expression, while the percentage seen in Treg and TGF-βand FoxP3 mRNA expression are negatively correlated with miR-200a expression. Our results provided a strong evidence that up-regulation of microRNA-200a in CD4+ T cells may induce immune dysfunction through Th17/Treg cells and relevant cytokines in PV patients.

RIPK1 downregulation in keratinocyte enhances TRAIL signaling in psoriasis

BACKGROUND

Psoriasis, a common inflammatory skin disorder characterized by scaly erythema and plaques, is induced by dysregulation of dendritic cell- and T cell-mediated immune reaction. Receptor-interacting protein kinase 1 (RIPK1) regulates inflammatory signaling in response to stimuli such as TNF-α, TRAIL, and TLRs, resulting in apoptosis, necroptosis and NF-κB activation. However, the physiological relevance in human epidermis remains elusive.

OBJECTIVE

In this study, we examined whether RIPK1 is involved in the pathogenesis of psoriasis vulgaris.

METHODS

Skin samples of eight patients with psoriasis vulgaris were investigated by western blotting and immunohistochemistry. The functions of RIPK1 in keratinocytes were examined by RT-PCR and ELISA in vitro. TRAIL-neutralization-experiment was employed in an imiquimod-induced murine psoriasis model.

RESULTS

In lesional psoriatic epidermis, RIPK1-expression was decreased compared with that in normal epidermis. Cytokines involved in the pathomechanism of psoriasis, such as IL-1β, IL-17A, IL-22 and TRAIL, reduced RIPK1-expression in normal human epidermal keratinocytes (HEK) in vitro. In addition, RIPK1-knockdown enhanced TRAIL-mediated expression of psoriasis-relating cytokines, such as IL-1β, IL-6, IL-8, TNF-α, in HEK. Numerous TRAIL-positive cells were detected in the dermis of lesional psoriatic skin, and TRAIL receptors were expressed in psoriatic epidermis and HEK in conventional cultures. Moreover, TRAIL-neutralization in an imiquimod-induced murine psoriasis model remarkably improved skin phenotypes, such as ear thickness, and TNF-α expression in lesional skin.

CONCLUSIONS

These results lead us to conclude that RIPK1-downregulation in keratinocytes increases their susceptibility to TRAIL stimulation, and plays a role in the pathogenesis of psoriasis vulgaris.

Association between LCE gene polymorphisms and psoriasis vulgaris among Mongolians from Inner Mongolia

The late cornified envelope (LCE) gene cluster is located on chromosome 1q21, including LCE1–LCE6. Several single nucleotide polymorphisms (SNPs) in the LCE cluster were associated with susceptibility to psoriasis in Chinese population. However, there is no report on the relationship in ethnic minority areas in China. This study aimed to investigate the association between the gene polymorphisms of LCE1B, LCE1C, LCE3A, LCE3D and psoriasis vulgaris among Mongolians from Inner Mongolia. Totally, 305 Mongolians with psoriasis vulgaris (PsV) and 383 healthy controls were enrolled in the study from 2006 to 2015. 7 SNPs including rs6701216, rs4112788, rs12023196, rs512208, rs4845454, rs4085613 and rs1886734, were selected for genotyping with ligase detection reaction (LDR). Statistical analysis was performed for comparisons of allele frequencies and genotype frequencies between the patient group and the control group. In this study, excluding rs4085613 and rs1886734, differences were detected in the allele frequencies of other 5 SNPs between the patients and controls. Genotype analysis showed that under the recessive inheritance model, the genotype frequencies of rs4845454, rs4112788 differed between the patients and controls (all p < 0.00 5).Under the dominant and the recessive model, the genotype frequencies of rs6701216, rs12023196 and rs512208 significantly differed between the patients and controls. The LD analysis showed that strong LD existed between rs6701216 and rs12023196, rs4845454 and rs4085613, rs4845454 and rs1886734, and rs4085613 and rs1886734. The SNPs rs6701216, rs4112788, rs12023196, rs512208 and rs4845454 in the LCE gene were associated with psoriasis vulgaris among Mongolians from Inner Mongolia.

[Therapy of Psoriasis Arthritis Taking into Account New Treatment Options]

Therapy of Psoriasis Arthritis Taking into Account New Treatment Options Abstract. Psoriatic arthritis occurs in about 20-30 % of patients with psoriasis. The disease is heterogeneous and can involve a variety of the distinct anatomical sites. The choice of medication depends on the type and the severity of clinical features. The recommendations of EULAR and GRAPPA serve as a guide for the choice of medication, which is used in sequential treatment steps. This is presented in our review in usable, simplified terms. Potential comorbidities leading to contraindication for certain treatments are considered. We present new and highly effective treatments, based on the pathogenesis of psoriasis and psoriatic arthritis, targeting the IL-23/IL-17 pathway.

Plasma miR-155, miR-203, and miR-205 are Biomarkers for Monitoring of Primary Cutaneous T-Cell Lymphomas

Primary cutaneous T-cell lymphomas (CTCL) affect the skin and tend to transform and spread. CTCL involves primarily the Mycosis fungoides (MF) and more aggressive Sezary syndrome (SS). Oncogenic microRNAs (miRs) are stable epigenetic inhibitors often deregulated in the tumour and detectable as biomarkers in non-cellular fractions of peripheral blood. The tumour-specific expression of miR-155, miR-203, and miR-205 was shown to correctly diagnose CTCL. We herein asked whether these microRNAs can be used as plasma biomarkers for clinical CTCL monitoring. Patients with CTCL (n = 10) and controls with non-malignant conditions (n = 11) repeatedly donated plasma samples every ca. five months. MicroRNAs were detected in the plasma samples by specifically-primed RT-PCR followed by multivariate analyses of the miR expression dynamics. We herein established the plasma miR-classifier for detecting CTCL based on the miR-155 upregulation and miR-203/miR-205 downregulation with 100% specificity and 94% sensitivity. The 3-miR-score in the consecutive samples coincided with the clinical outcome of MF and SS patients such as the therapy response or changes in the clinical stage or tumor size. Quantitation of the selected microRNAs in plasma is a specific and straightforward approach for evaluating CTCL outcome representing, thus, a valuable tool for CTCL diagnostics and therapy response monitoring.

Differences in expression of serum protein in patients with psoriasis vulgaris and blood heat syndrome and healthy volunteers

To explore the mechanism of psoriasis vulgaris (PV), serum protein expression profiles between PV patients with blood-heat syndrome and healthy volunteers were detected by isobaric tags for relative and absolute quantitation (iTRAQ). First, sera from 15 PV patients with blood-heat syndrome and 10 healthy volunteers were collected; then, serum proteins were separated and hydrolyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and a specific iTRAQ marker enzyme respectively after further purification and protein abundance treatment. Compared with the control group, differentially expressed proteins in PV patients with blood-heat syndrome were identified and analyzed by tandem mass spectrometry. A total of 787 proteins were identified and 718 proteins had a functional annotation with gene ontology (GO) by iTRAQ in the current study. Significant differences (P &lt;0.05) and great differences (P &lt;0.01) were found in 681 proteins and 536 proteins respectively between the patient group and healthy group. ). Different protein expression profiles in serum existed between PV patients with blood-heat syndrome and healthy volunteers; the differences largely involved immune-related proteins and lipoproteins. The proteins specific for PV with blood-heat syndrome deserves further investigation.

Autoimmune aspects of psoriasis: Heritability and autoantigens

Chronic immune-mediated disorders (IMDs) constitute a major health burden. Understanding IMD pathogenesis is facing two major constraints: Missing heritability explaining familial clustering, and missing autoantigens. Pinpointing IMD risk genes and autoimmune targets, however, is of fundamental importance for developing novel causal therapies. The strongest association of all IMDs is seen with human leukocyte antigen (HLA) alleles. Using psoriasis as an IMD model this article reviews the pathogenic role HLA molecules may have within the polygenic predisposition of IMDs. It concludes that disease-associated HLA alleles account for both missing heritability and autoimmune mechanisms by facilitating tissue-specific autoimmune responses through autoantigen presentation.

Glycemic Control in the Treatment of Psoriasis

Psoriasis is a common chronic inflammatory skin disease that manifests as scaly erythematous plaques as a consequence of keratinocyte hyperproliferation and inflammation. It is commonly associated with diabetes, obesity, and the metabolic syndrome. While there are numerous approved treatment options available, they have limitations including availability, toxicities such as immunosuppression, and high cost. There is increasing evidence to suggest that several hypoglycemic agents used in the treatment of type 2 diabetes, including glucagon-like peptide-1 receptor agonists, dipeptidyl peptidase-4 inhibitors, thiazolidinediones and biguanides, exert beneficial effects in psoriasis. In this review, we summarize the growing evidence supporting the therapeutic role of hypoglycemic agents in psoriasis and discuss the potential underlying mechanisms. We suggest that dermatologists consider the use of hypoglycemic agents in psoriasis especially in cases with coexisting diabetes and in cases in which immunosuppression is contraindicated. Earlier referral to endocrinology in patients with concomitant diabetes may be appropriate.

Chinese herbal Pulian ointment in treating psoriasis vulgaris of blood-heat syndrome: a multi-center, double-blind, randomized, placebo-controlled trial

BACKGROUND

Traditional Chinese medicine (TCM) has a long history in the treatment of psoriasis vulgaris. We aimed to evaluate the clinical efficacy and safety of Chinese herbal Pulian ointment in treating psoriasis vulgaris of blood-heat syndrome.

METHODS

A multicenter, randomized, double-blind, placebo-controlled trial was conducted. Participants with psoriasis vulgaris of blood-heat syndrome were blinded and randomized to receive Pulian ointment or placebo ointment twice daily for 4 weeks, with follow-up 8 weeks after treatment. Psoriasis Area Severity Index (PASI) scores, severity of each symptom and area of skin lesion and quality of life were assessed at baseline, 2 weeks, and 4 weeks. Adverse events were recorded during the study. SAS 9.4 software and SPSS 17.0 software was applied for data analysis.

RESULTS

A total of 300 participants with psoriasis vulgaris of blood-heat syndrome were assessed for eligibility, and 294 were randomly assigned to the Pulian ointment and placebo group from six study centers. Full analysis set (FAS): after 4 weeks of treatment, there were significant differences between groups in PASI score and the separate score of skin lesion area, favoring Pulian ointment group (P < 0.05). However, no significant differences were observed in scores of scaling, erythema and induration/thickness (P > 0.05). Per protocol set (PPS): There was no statistically significant difference in PASI score and separate score of each symptom and area of skin lesion between two groups (P > 0.05). Quality of life measured by Hamilton Anxiety Rating Scale (HAMA) and 36-Item Short Form Health Survey (SF-36) improved after treatment in both groups, but there was no significant difference between the two groups (P > 0.05). After being followed up for 8 weeks, the total relapse rates of the Pulian Ointment group and placebo group were 5.88 and 8.45%, respectively, and the difference was not statistically significant between the two groups (P > 0.05). No adverse event was observed in both groups throughout the study.

CONCLUSIONS

Pulian Ointment seems effective and well tolerated in improving the PASI score and separate score of skin lesion area for patients with psoriasis vulgaris of blood-heat syndrome. Further research could build on the current study to explore whether other preparation forms and greater intervention intensity are necessary for better therapeutic effects.

Profile of Tumour Necrosis Factor Alpha -308 G/A Gene Polymorphism in Psoriatic Patients in Karnataka, India

INTRODUCTION

Tumour necrosis factor-alpha (TNFα) gene -308G/A polymorphism (rs1800629) are associated with psoriasis in several populations worldwide. Presently, there is no literature on the status of this polymorphism in the South Indian population.

AIM

To determine the profile of TNFα -308G/A polymorphism among psoriatic patients.

MATERIALS AND METHODS

This case-control study involved 74 patients with Psoriasis Vulgaris (PsV) and 74 age and gender matched healthy individuals. Patients were recruited from the Department of Dermatology of R.L. Jalappa Hospital and Research Center, Tamaka, Kolar, Karnataka, India, from March 2014 to March 2016. TNFα -308G/A polymorphism was genotyped by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method.

RESULTS

The frequency of TNFα -308A allele 7.4% among psoriatic and 8.8% among non-psoriatic individuals. The difference was not statistically significant (p=0.82).

CONCLUSION

Our results indicate that TNFα gene -308G/A polymorphism is not a significant marker for the risk of developing PsV among South Indian (Karnataka) psoriatic patients.

Serum peptides as putative modulators of inflammation in psoriasis

BACKGROUND

Psoriasis is a refractory inflammatory disease, however, its pathophysiology is still not fully understood.

OBJECTIVE

We tried to identify novel serum peptides associated with the pathophysiology of psoriasis.

METHODS

Serum peptides from 24 patients with psoriasis vulgaris (PV), 10 patients with psoriatic arthritis (PsA), 14 patients with atopic dermatitis (AD), and 23 healthy control (HC) subjects were analyzed by mass spectrometry. The effects of some peptides on the secretion of humoral factors from dermal cells were investigated by cytokine arrays and ELISAs.

RESULTS

A total of 93 peptides were detected. 24, 20, 23, and 2 peptides showed at least 1.2-fold difference in ion intensity between the psoriasis (PV+PsA) and HC groups, between the PV+PsA and AD groups, between the PV and PsA groups, and between patients with severe-to-moderate PV (n=6) and those with mild PV (n=18), respectively (p<0.05). 13 out of 27 peptides that showed at least 1.5-fold ion intensity difference in the abovementioned 4 comparisons were identified. The parent proteins of the identified peptides included a coagulation factor, proteins involved in the maintenance of skin, and a protein relating to cytoskeleton. We focused on 2 peptides that were increased in the PV+PsA group: a fibrinogen α chain-derived peptide (1462m/z), the unmodified form of which was fibrinopeptide A-des-alanine (FPAdA), and a filaggrin (FLG)-derived peptide (1977m/z), a modified form of FLG_2099-2118 (Q₂₀₉₉pE, Q₂₁₁₅E; FLG-pEE). FPAdA stimulation increased the secretion of GROα from dermal microvascular endothelial cells (dMVECs) and decreased the secretion of lipocalin-2 from keratinocytes in comparison to FPAdA-resequenced peptide stimulation (GROα, 280.9±7.3pg/mL vs. 229.6±5.0pg/mL, p<0.001; lipocalin-2, 273±13pg/mL vs. 350±10pg/mL, p<0.01). Interestingly, FLG-pEE stimulation decreased the secretion of GROα, IL-8, and MCP-1 from dMVECs in comparison to FLG-derived control peptide stimulation (GROα, 844.3±47.5pg/mL vs. 1038.5±96.9pg/mL, p<0.05; IL-8, 2240.1±172.6pg/mL vs. 3221.8±523.7pg/mL, p<0.05; MCP-1, 4057.8±157.2pg/mL vs. 4619.1±213.4pg/mL, p<0.05).

CONCLUSIONS

The results suggested that some serum peptides are involved in the pathophysiology of psoriasis, regulating the secretion of inflammatory chemokines and an antimicrobial protein. The modulation of serum peptides may be a potential therapeutic strategy for psoriasis.

MicroRNA138 regulates keratin 17 protein expression to affect HaCaT cell proliferation and apoptosis by targeting hTERT in psoriasis vulgaris

The purpose of this study is to explore the how microRNA-138 (miR-138) affects the expression of keratin 17 (K17) and psoriasis development. Twenty-eight skin lesions from patients with psoriasis vulgaris and twenty-four normal skin tissues from healthy controls were collected. The HaCaT cells were assigned into blank, negative control (NC), miR-138 mimic, miR-138 inhibitor, hTERT siRNA and miR-138 inhibitor+hTERT siRNA groups. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect the miR-138 expression. The hTERT and K17 protein expression were testified by Western Blotting. MTT assay, flow cytometry with PI single staining and Annexin V/PI double staining were performed to detect the cell proliferation activity, cell cycle and apoptosis, respectively. Compared with the healthy skin, the expression of miR-138 decreased in the psoriatic skin, but hTERT and K17 protein expressions increased. The miR-138 mimic and hTERT siRNA groups showed significantly decreased hTERT and K17 protein expressions, inhibited cell proliferation, increased number of cells at G1 phase and elevated apoptosis rate in comparison to the rest three groups. The hTERT and K17 protein expressions in the miR-138 inhibitor group were up-regulated with promoted cell proliferation and reduced apoptosis rate as compared with the other four groups. In the miR-138 inhibitor+hTERT siRNA group, the hTERT and K17 protein expressions, cell proliferation and apoptosis were intermediate between the miR-138 inhibitor and hTERT siRNA groups. These findings indicated that the expression of miR-138 was lower in the psoriatic skin, which was negatively correlated to K17 expression. MiR-138 may regulate K17 protein expression to affect HaCaT cell proliferation and apoptosis by targeting hTERT gene.

Exacerbation of Darier Disease under Interferon-α-2a Therapy with Clinical Signs of Lichen Nitidus

Darier disease/dyskeratosis follicularis is a genodermatosis characterized by brown, oily keratotic papules and plaques in the seborrheic areas of the face and chest. Responsible for the disease are mutations in the ATP2A2 gene, encoding SERCA2, a calcium pump of the sarco-/endoplasmic reticulum. Mechanical trauma, heat, humidity, ultraviolet B radiation, oral corticosteroids and lithium are known trigger factors of the disorder. We report on a 48-year-old German woman with a flare-up of Darier disease under interferon-α-2a (IFNα-2a) therapy with clinical signs of lichen nitidus. Due to the fulminant course of the eruption, we suspected IFNα as a possible trigger. To our knowledge there are no reports regarding exacerbation of Darier disease during IFNα therapy. Possible pathogenetic mechanisms are being discussed.

A statistical analysis plan for the efficiency and safety of Chinese herbal medicine used concurrently with topical therapy for psoriasis vulgaris

BACKGROUND

Psoriasis vulgaris (PV) has been causing increasing concern due to its highly prevalent, harmful and therapy-resistant characteristics. The YXBCM01 (Chinese herbal medicine) for PV trial evaluates the effects of YXBCM01 on relapse rate in patients suffering from PV. As an update to the published design and method for the trial, this paper presents the statistical plan for the main publication to avoid the risk of outcome reporting bias, selective reporting, and data-driven results.

METHODS/DESIGN

This trial is a multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical trial. A total of 600 PV patients (300 in each group) will be randomized to one of two arms: participants in the experimental group will receive the YXBCM01 granule 5.5 g twice daily for 12 weeks. Placebo granules are given to patients in the control group at a dose of 5.5 g twice daily for 12 weeks. The sequential topical therapy is administrated simultaneously to all eligible patients by using calcipotriol betamethasone ointment once daily (a treatment area of up to 30 % body surface area (BSA), fingertip unit is recommended) in the first 4 weeks (maximum of 100 g weekly), followed by calcipotriol betamethasone ointment once daily for the remaining 8 weeks (maximum of 100 g weekly). The primary outcome measure is relapse rate in the treatment period and follow-up period. The secondary outcome measures include time to relapse, time to onset, rebound rate, cumulative consumption of topical medicine, visual analog scale (VAS), BSA, the Dermatology Life Quality Index (DLQI) and the Medical Outcomes Study (MOS) 36-item short form health survey (SF-36).

CONCLUSIONS

Application of this statistical analysis plan to the YXBCM01 for PV trial will facilitate unbiased evaluation of these important clinical data. This study will provide evidence regarding the value of YXBCM01 as an intervention for PV patients.

An extremely rare case of tubo-ovarian abscesses involving corynebacterium striatum as causative agent

Background

We present an extremely rare case of tubo-ovarian abscesses involving Corynebacterium striatum (C. striatum) as causative agent in a 53-year-old woman.

Case presentation

The patient presented with stomach pain, chills, and nausea. Her medical history included poorly controlled psoriasis vulgaris and diabetes. Laboratory and imaging findings led to diagnosis of septic shock due to tubo-ovarian abscesses. She was treated with antibiotic therapy and surgery to remove the left adnexa. Various cultures detected Prevotella spp. and C. striatum. We concluded that C. striatum from skin contaminated by psoriasis vulgaris had caused the tubo-ovarian abscesses by way of ascending infection.

Conclusions

This may be the first known case of tubo-ovarian abscesses due to C. striatum. In patients whose skin has been weakened by psoriasis vulgaris or other infections, Corynebacterium should be considered as causative microorganisms, and antibiotic therapy including vancomycin should be administered.

Perception of psoriasis treatment in the outpatient setting: survey of patients and their prescribing physicians

BACKGROUND

Patients' perception of disease management can influence compliance to treatment and thus affect outcome.

OBJECTIVE

To survey patients and physicians on their perceptions of biologic therapy for treating psoriasis in an outpatient setting.

METHODS

The subjective impact of intravenous treatment of severe psoriasis on patients and physicians in the outpatient setting was determined via two surveys.

RESULTS

Between September and November 2014, 24 dermatologists and 90 patients were surveyed. Treatment with biologic agents in the outpatient setting was associated with a high level of patient satisfaction: 93.3% of patients considered their psoriasis well controlled and 46.1% reported complete control. Patients highly valued the feeling of greater disease control (72.2%), regular follow-up (66.7%) and rapid improvement of psoriasis (58.9%) when attending an outpatient setting. Other positive aspects of outpatient treatment were control of other health issues and perceived improvements in quality of life (QoL). Outpatient attendance was high; with 90% of patients keeping scheduled appointments and 79.2% of physicians acknowledged that they were able to monitor their patients' condition more closely.

CONCLUSION

Administration of treatment in an outpatient setting may provide a feeling of improved QoL and disease control.

Olfactory functions in patients with psoriasis vulgaris: correlations with the severity of the disease

It is well known that psoriasis is not only limited to skin, but a systemic autoimmune disease with various comorbidities. Olfactory dysfunction, one of as a common but lesser known symptom of patients with autoimmune diseases, often presents with smell loss. The aim of this study was to assess the olfactory functions in patients with psoriasis and to compare with healthy controls. A total of 50 patients with psoriasis and 43 control subjects were included to the study. The clinical severity of psoriasis was calculated by psoriasis area and severity index (PASI). Patients were classified into two groups according to PASI score as mild (PASI ≤10) and moderate-severe (PASI >10). Olfactory function was evaluated with "Sniffin'Sticks" test. Total test scores (max. 48 points) of threshold, discrimination, and identification (TDI) were classified as normal olfaction = normosmia (>30.3 points), decreased olfaction = hyposmia (16.5-30.3 points) and loss of olfaction = anosmia (<16.5 points). Psoriasis patients had significantly lower smell scores compared with healthy controls (p < 0.001). Of the 50 psoriasis patients, 40 (80 %) were hyposmic. We found negative correlation between TDI and PASI (r = -0.34, p = 0.014). The TDI scores of the patients with moderate-severe psoriasis (PASI score >10) were found to be significantly lower than the patients with mild psoriasis (PASI ≤10) (p < 0.001). Olfactory dysfunction in patients with psoriasis could be thought as a comorbidity as in other inflammatory disorders. Physicians should be aware of olfactory impairment when evaluating psoriasis patients in their clinical practice.

A Patient with Refractory Psoriasis Who Developed Sebaceous Carcinoma on the Neck during Cyclosporine Therapy and Showed Rapid Progression

We report a patient who developed sebaceous carcinoma on the neck during therapy with immunosuppressive agents (cyclosporine, corticosteroid, methotrexate) for refractory psoriasis vulgaris, which showed rapid enlargement, leading to a fatal outcome. Multiple-organ metastases were detected. Weekly carboplatin + paclitaxel therapy resulted in the disappearance of tumor cells, but the patient died of febrile neutropenia. The development of sebaceous carcinoma is rare among psoriasis patients receiving immunosuppressive agents including cyclosporine.

[Autoimmune reactions in psoriasis : Spotlight]

BACKGROUND

Psoriasis is a human leukocyte antigen (HLA)-associated T‑cell-mediated disorder.

OBJECTIVES

The role of the main psoriasis risk allele HLA-C*06:02 in disease manifestation and the mechanisms which activate the pathogenic T‑cell response in the skin of psoriasis patients remained elusive.

MATERIALS AND METHODS

Key to the immune pathogenesis of psoriasis was the analysis of the specificity of the infiltrating lesional psoriatic CD8(+) T cells

RESULTS AND CONCLUSION

Analyses of the lesional psoriatic T‑cell reactivity demonstrate that psoriasis is an autoimmune disease. It is based on an autoimmune response against melanocytes which is preferentially mediated by HLA-C*06:02 through autoantigen presentation. Here we discuss the mechanisms of this autoimmune response in the context of the polygenic psoriatic predisposition.

TLR2 and TLR4 polymorphisms in Southern Chinese Psoriasis Vulgaris patients

BACKGROUND

The toll-like receptors-(TLR)-2 and -4 play a role in the innate immune system and drive the autoimmune T cell cascade in psoriasis. But little is known about the association of the polymorphisms of TLR2/TLR4 and psoriasis vulgaris (PsV).

METHODS

We performed a hospital-based association study involved in355 PsV patients and 213 controls. Genotyping of 11 SNPs rs4696480(-16934A/T), rs121917864 (2029C/T;Arg677Trp), rs5743708 (2408G/A;Arg753Gln), rs3804099 (+597T/C), rs5743699(+1349T/C) of TLR2 on chromosome 4q32; and rs1927914 (-6143A/G), rs10759932(-5724T/C), rs4986790 (896A/G; Asp299Gly), rs4986791 (1196C/T; Thr399lle); rs11536889(+7263G/C), rs11536891(+8469T/C) of TLR4 on chromosome 9q33.1 were determined using SNaPshot Multiplex Kit (Applied Biosystems Co., USA).

RESULTS

We did not detect the presence of any of the five rare SNPs (rs5743708, rs121917864, rs5743699, rs4986790, rs4986791). The comparison of allele distributions revealed that only one SNP (rs3804099) of 6 common SNPs(rs10759932, rs11536889, rs11536891, rs1927914, rs3804099, rs4696480) was significant associated with the risk of PsV (P<0.01; FDR p-Value). However, there were no significant differences found in other subphenotypes of family history or PASI between patients positive and those negative for a particular phenotype.

CONCLUSIONS

The SNP rs3804099 of TLR2 may have significant effects on heritability of PsV in our Chinese population. TLR2 and its pathway might take part in the pathogenesis of PsV.
