In this study, we aimed to detect the levels of Th1/Th2 cytokine-associated transcription factors and T-lymphocyte clone in peripheral blood mononuclear cells(PBMCs) derived from EP patients, and gene expression level of T-bet/GATA-3 in skin lesion. The potential role of Th1/Th2 reaction pattern played in the pathogenesis of EP was also discussed. Serum levels of IFN-γ, IL-2, IL-4 and IL-10 were quantified by ELISA among 16 EP patients, 20 psoriasis vulgaris(PV) patients and 15 healthy controls. The expression levels of T-bet/GATA-3 in the skin lesion and PBMCs were examined by real-time qPCR. The ratio of Th1/Th2 was measured by flow cytometry. The levels of IFN-γ, IL-2, IL-4 and IL-10 were higher in EP patients than in the healthy controls. The levels of IL-4 and IL-10 were 69.44±11.45 and 12.62±4.57 pg/mL, respectively, in EP patients, significantly higher than those in PV patients and healthy controls(P〈0.05). Flow cytometry revealed the levels of both Th1 and Th2 in PBMCs from EP patients were higher than those in healthy controls, and the Th1/Th2 ratio was dramatically lower than in PV patients(P〈0.01). The ratios of IFN-γ/IL-4 and T-bet/GATA-3 in EP patients were both less than 1.0, suggesting a reversal when compared with the other two groups. Our study indicated that the EP patients exerted a Th1/Th2 bidirectional response pattern, and the balance of Th cell subsets inclines to Th2, which might be one of the important mechanisms of EP pathogenesis.展开更多

Erythrodermic psoriasis(EP) is the commonest type of erythroderma. In addition, there are drug-induced erythroderma, erythroderma secondary to preexisting dermatoses, malignancy-related erythroderma, and idiopathic erythroderma of unknown etiology. Erythroderma of different etiologies has various clinical manifestations, resulting in relevant curative effects and outcomes. In this article, we retrospectively investigated 205 erythroderma patients about clinical symptoms, auxiliary examination and treatments, and evaluated the efficacy and prognosis. There were 84 cases of EP among 205 patients, 10 cases of erythroderma caused by specific drugs, 77 cases of erythroderma secondary to preexisting dermatoses(excluding psoriasis), 7 cases of erythroderma patients suffering from malignancy and 27 cases with unknown causes. We concluded that the etiology of male patients in different age groups had significant difference. The incidence of EP was the highest among all types. The EP was commonly accompanied with hypoproteinemia, and changed into psoriasis vulgaris after treatment. Drug-induced erythroderma was commonly accompanied with fever, and mostly cured by systematic steroid therapy. For erythroderma secondary to preexisting dermatoses, the original dermatoses must be actively treated to achieve a satisfying prognosis. Erythroderma with malignancy or unknown causes had long-term duration, poor response to the treatment, and high potential to relapse. Therefore, clarifying the etiology, providing an appropiate and individual regimen, and regular follow-up are crucial for the successful treatment of erythroderma with unknown causes.展开更多

Patients and Methods: Over the past 10 years;a total of 21 patients, with long-term (17 months) and extensive psoriasis (P) with psoriasis area severity index (PASI) >29, were evaluated. Results: Two patients had nephrotic syndrome (proteinuria 3.9 and 3.6 g/day) and decrease creatinine clearance (46 and 62 ml/minute). Their renal biopsy revealed Congo-red (+) nodular glomerulosclerosis that lacked immune-deposits and resisted wash with K-permanganate wash indicating SSA. Three months subsequent to Cyclosporin A (CyA) therapy with 100 mg twice daily;psoriasis improved in all patients with decrease in (PASI) from 29.5 to 3.5 1. In the 2 patients with SSA;proteinuria decreased to 2.1 and 1.8 g/day and creatinine clearance improved to 51 and 69 ml/minute. Such improvement persisted up to 2 years of follow up and up to 78 months in patients with SSA. Conclusion: psoriasis-induced SSA is an autoimmune disease, with genetic predisposition that is amenable to CyA therapy.展开更多

Specifically, there is a significant correlation between psoriasis and depression, and they show the relationships of reciprocal causation and mutual promotion. Psoriasis with depression is more harmful than simple psoriasis, and its prognosis is worse, which brings a huge burden to the family and society and is worthy of clinical attention. Based on the pathogenic factors of western medicine and pathogenesis of traditional Chinese medicine in psoriasis with depression, the paper summarized and elaborated the research progress on the mechanism of traditional Chinese medicine in the treatment of psoriasis with depression, in order to provide new ideas for clinical treatment.展开更多

Ever since the observation of microvascular hyperplasia in psoriatic lesions, there has been a growing focus on exploring the intricate relationship between microcirculation and psoriasis. Furthermore, the potential utility of microcirculatory changes as prognostic indicators for psoriasis has garnered significant attention. This paper provides a comprehensive review of the role of skin microcirculation in psoriasis pathogenesis and its potential application as a clinical prognostic indicator.展开更多

文摘Background: Systemic secondary amyloidosis (SSA) is associated with chronic inflammatory disorders and/or chronic infections. Patients and Methods: Over the past 10 years;a total of 21 patients, with long-term (17 months) and extensive psoriasis (P) with psoriasis area severity index (PASI) >29, were evaluated. Results: Two patients had nephrotic syndrome (proteinuria 3.9 and 3.6 g/day) and decrease creatinine clearance (46 and 62 ml/minute). Their renal biopsy revealed Congo-red (+) nodular glomerulosclerosis that lacked immune-deposits and resisted wash with K-permanganate wash indicating SSA. Three months subsequent to Cyclosporin A (CyA) therapy with 100 mg twice daily;psoriasis improved in all patients with decrease in (PASI) from 29.5 to 3.5 1. In the 2 patients with SSA;proteinuria decreased to 2.1 and 1.8 g/day and creatinine clearance improved to 51 and 69 ml/minute. Such improvement persisted up to 2 years of follow up and up to 78 months in patients with SSA. Conclusion: psoriasis-induced SSA is an autoimmune disease, with genetic predisposition that is amenable to CyA therapy.
文摘BACKGROUND Moyamoya syndrome(MMS)is a group of diseases that involves more than one underlying disease and is accompanied by moyamoya vascular phenomena.Psoriasis is a chronic immune skin disease closely linked to high blood pressure and heart disease.However,psoriasis-related MMS has not been reported.CASE SUMMARY We collected data on patients with stroke due to MMS between January 2017 and December 2019 and identified four cases of psoriasis.Case histories,imaging,and hematological data were collected.The average age of the initial stroke onset was 58.25±11.52 years;three cases of hemorrhagic and one case of ischemic stroke were included.The average duration from psoriasis confirmation to the initial MMS-mediated stroke onset was 17±3.56 years.All MMS-related stenoses involved the bilateral cerebral arteries:Suzuki grade III in one case,grade IV in two cases,and grade V in one case.Abnormally elevated plasma interleukin-6 levels were observed in four patients.Two patients had abnormally elevated immunoglobulin E levels,and two had thrombocytosis.All four patients received medication instead of surgery.With an average follow-up time of 2 years,two causing transient ischemic attacks occurred in two patients,and no hemorrhagic events occurred.CONCLUSION Psoriasis may be a potential risk factor for MMS.Patients with psoriasis should be screened for MMS when they present with neurological symptoms.

文摘Background:Psoriasis is a disease caused by genetics and immune system dysfunction,affecting the skin and joints.Toll-like receptors(TLRs)play an important role in triggering the innate immune response and controlling adaptive immunity.The role of TLR2 in the progression of psoriasis is not well understood.Methods:A case-control study was conducted on a northern Chinese Han population,consisting of psoriasis patients and healthy control subjects.Genotyping was performed using the tetra-primer amplification refractory mutation system-polymerase chain reaction(ARMS-PCR),and allele and genotype frequencies of four SNPs in TLR2 were analyzed in 270 psoriasis patients and 246 healthy controls.Results:Four TLR2 SNPs(rs11938228,rs4696480,rs3804099,rs5743699)were genotyped and found to be in linkage disequilibrium.The genotype distributions of rs11938228 and rs4696480 in two groups were in Hardy-Weinberg equilibrium and statistically significant except for the overdominance model.The haplotypes ATTC and ATCC were found to be protective against psoriasis.Conclusion:Our study found a correlation between TLR2 genetic variations and the likelihood of psoriasis in northern China.
文摘Objective Secoemestrin C(SC),an epitetrathiodioxopiperazine isolated from Aspergillus nidulans,has been previously reported to have immunomodulatory and hepatoprotective effects against acute autoimmune hepatitis.However,the effect of SC on regulating the inflammation and its underlying mechanisms in the pathogenesis of psoriasis remain unclear.This study aimed to evaluate the effects of SC on inflammatory dermatosis both in vitro and in vivo.Methods In vitro,HaCaT cells were induced with tumor necrosis factor-alpha(TNF-α,10 ng/mL)to establish an inflammatory injury model,and the expression of nuclear transcription factor-κB(NF-κB)pathway components was measured using qRT-PCR and Western blotting.An in vivo mouse model of imiquimod(IMQ)-induced psoriasis-like skin inflammation was used to evaluate the effectiveness of SC in alleviating psoriasis.Results SC significantly blocked the activation of NF-κB signaling in TNF-α-stimulated HaCaT cells.In addition,systemic and local administration of SC improved psoriatic dermatitis in the IMQ-induced mouse model.SC reduced skin scale and significantly inhibited the secretion of inflammatory factors in skin lesions.Conclusion The protective effect of SC against psoriatic-associated inflammation reveals its potential therapeutic value for treating psoriasis.

文摘Tumour immunotherapy represented by immune checkpoint inhibitors(ICIs)has greatly improved the overall prognosis of patients with malignant tumours,and is regarded as an important breakthrough in the field of medicine in recent years.ICIs have gradually become the core of tumour therapy and are increasingly used in the clinic.In order to achieve early clinical prediction and management of immune-related adverse events(irAEs),it is still necessary to perform further research on the mechanisms,risk factors,and predictors of irAE occurrence in the future.Zhou et al describe the consultation of a patient with advanced gastric cancer combined with chronic plaque psoriasis.This case provides an important reference for the use of programmed cell death protein-1(PD-1)inhibitors in patients of tumours combined with chronic plaque psoriasis.This case also highlights that screening of high-risk groups for irAEs is critical before applying PD-1 inhibitors to patients with chronic psoriasis combined with tumours.PD-1 inhibitors are new and potent antineoplastic agents that can cause serious immunerelated adverse events such as toxic epidermal necrolysis release and psoriasis.Glucocorticosteroids are the first-line agents for irAEs.The incidence of rheumatic irAEs may be higher in reality,which will inevitably become a new challenge for rheumatologists and dermatologists.

文摘Psoriasis is a kind of immune-mediated, chronic, inflammatory skin disease, which is often associated with different degrees of psychological disorders. Specifically, there is a significant correlation between psoriasis and depression, and they show the relationships of reciprocal causation and mutual promotion. Psoriasis with depression is more harmful than simple psoriasis, and its prognosis is worse, which brings a huge burden to the family and society and is worthy of clinical attention. Based on the pathogenic factors of western medicine and pathogenesis of traditional Chinese medicine in psoriasis with depression, the paper summarized and elaborated the research progress on the mechanism of traditional Chinese medicine in the treatment of psoriasis with depression, in order to provide new ideas for clinical treatment.

文摘Objective Psoriasis is often combined with metabolic abnormalities,such as obesity and diabetes.The upregulation of chemerin,which is an essential protein produced primarily from white fat,is strongly correlated to the development of psoriasis.However,there is no clarification on its exact function and mechanism in disease pathogenesis.The present study aims to determine its function and mechanism in disease pathogenesis.Methods The present study used a psoriasislike inflammatory cell model and imiquimod(IMQ)-induced mouse model to confirm whether chemerin is upregulated in psoriasis patients.Results Chemerin enhanced the keratinocyte proliferation,inflammatory cytokine secretion,and activation of the MAPK signaling pathway.Crucially,the intraperitoneal injection of neutralizing anti-chemerin antibody(ChAb)diminished the epidermal proliferation and inflammation in the IMQ-induced mouse model.Conclusion The present results indicate that chemerin promotes keratinocyte proliferation,and enhances the production of inflammatory cytokines,thereby aggravating the psoriasis.Thus,chemerin can be a prospective target for the treatment of psoriasis.

文摘Psoriasis is a chronic inflammatory skin disease characterized by erythema,scaling,and skin thickening.Topical drug application is recommended as the first-line treatment.Many formulation strategies have been developed and explored for enhanced topical psoriasis treatment.However,these preparations usually have low viscosity and limited retention on the skin surface,resulting in low drug delivery efficiency and poor patient satisfaction.In this study,we developed the first water-responsive gel(WRG),which has a distinct water-triggered liquid-to-gel phase transition property.Specifically,WRG was kept in a solution state in the absence of water,and the addition of water induced an immediate phase transition and resulted in a high viscosity gel.Curcumin was used as a model drug to investigate the potential of WRG in topical drug delivery against psoriasis.In vitro and in vivo data showed that WRG formulation could not only extend skin retention but also facilitate the drug permeating across the skin.In a mouse model of psoriasis,curcumin loaded WRG(CUR-WRG)effectively ameliorated the symptoms of psoriasis and exerted a potent anti-psoriasis effect by extending drug retention and facilitating drug penetration.Further mechanism study demonstrated that the anti-hyperplasia,anti-inflammation,anti-angiogenesis,anti-oxidation,and immunomodulation properties of curcumin were amplified by enhanced topical drug delivery efficiency.Notably,neglectable local or systemic toxicity was observed for CUR-WRG application.This study suggests that WRG is a promising formulation for topically psoriasis treatment.
文摘Psoriasis, a chronic and recurring inflammatory skin disorder, is distinguished by the excessive proliferation of keratinocytes, immune cell infiltration, and angiogenesis. Ever since the observation of microvascular hyperplasia in psoriatic lesions, there has been a growing focus on exploring the intricate relationship between microcirculation and psoriasis. Furthermore, the potential utility of microcirculatory changes as prognostic indicators for psoriasis has garnered significant attention. This paper provides a comprehensive review of the role of skin microcirculation in psoriasis pathogenesis and its potential application as a clinical prognostic indicator.

文摘Psoriasis is an inflammatory skin disease that is intricately linked to oxidative stress.Antioxidation and inhibition of abnormal proliferation of keratinocytes are pivotal strategies for psoriasis.Delivering drugs with these effects to the site of skin lesions is a challenge that needs to be solved.Herein,we reported a nanotransdermal delivery system composed of all-trans retinoic acid(TRA),triphenylphosphine(TPP)-modified cerium oxide(CeO2)nanoparticles,flexible nanoliposomes and gels(TCeO_(2)-TRA-FNL-Gel).The results revealed that TCeO_(2)synthesized by the anti-micelle method,with a size of approximately 5 nm,possessed excellent mitochondrial targeting ability and valence conversion capability related to scavenging reactive oxygen species(ROS).TCeO_(2)-TRA-FNL prepared by the film dispersion method,with a size of approximately 70 nm,showed high drug encapsulation efficiency(>96%).TCeO_(2)-TRA-FNL-Gel further showed sustained drug release behaviors,great transdermal permeation ability,and greater skin retention than the free TRA.The results of in vitro EGF-induced and H2O2-induced models suggested that TCeO_(2)-TRA-FNL effectively reduced the level of inflammation and alleviated oxidative stress in HaCat cells.The results of in vivo imiquimod(IMQ)-induced model indicated that TCeO_(2)-TRA-FNL-Gel could greatly alleviate the psoriasis symptoms.In summary,the transdermal drug delivery system designed in this study has shown excellent therapeutic effects on psoriasis and is prospective for the safe and accurate therapy of psoriasis.

文摘Objective:To investigate the anxiety status of patients with psoriasis vulgaris,and analyze the correlation between anxiety and severity of the disease,oxidative stress factors and inflammatory factors.Methods:From August 2021 to February 2022,84 patients with psoriasis in the Dermatology Department of Dongzhimen Hospital of Traditional Chinese Medicine were recruited.Hamilton anxiety scale(HAMA),psoriasis lesion area and severity index(PASI),VAS pruritus scale(VAS)were collected to detect serum malondialdehyde(MDA),superoxide dismutase(SOD),glutathione peroxidase(GSH px),interleukin-6(IL-6),interleukin-17A(IL-17A),and tumor necrosis factor-α(TNF-α).Based on the HAMA score,a group controlled study and correlation analysis were conducted.In addition,the HAMA scores of 84 healthy people were collected for a controlled study.Results:HAMA score of patients with psoriasis vulgaris was higher than that of healthy people(Z=-7.730,P<0.05).There were differences in PASI,VAS scores,MDA,SOD,GSH px,IL-6,IL-17A secretion levels between psoriasis vulgaris patients with anxiety and psoriasis vulgaris patients without anxiety.HAMA score was positively correlated with PASI and VAS scores in patients with psoriasis vulgaris(r=0.564,0.513,P<0.05).It was positively correlated with MDA,IL-6,IL-17A in serum(r=0.390,0.355,0.248,P<0.05).It was negatively correlated with SOD and GSH px(r=-0.313,-0.502,P<0.05);and TNF-αnot relevant.Conclusion:The anxiety risk of psoriasis patients was higher than that of healthy people;anxiety is closely related to psoriasis,and is reflected in the skin lesions,itching,oxidative stress and inflammatory factor levels of psoriasis patients.The comorbidity mechanism of anxiety and psoriasis may be related to oxidative stress and up regulation of inflammatory factors.
文摘BACKGROUND Atopic dermatitis and asthma are two diseases whose pathogenesis is largely attributable to the activation,at least in the initial stages,of T helper(Th)-2 Lymphocytes,the related cytokine axis,and B lymphocytes with antibody production.Psoriasis is conversely a pathology resulting from a recruitment of Th-17 and Th-1 lymphocytes,after an initial role of innate immunity.Mepolizumab is a humanized monoclonal antibody directed against interleukin(IL)-5,a central cytokine in the Th-2 axis,therefore involved in the pathogenesis of asthma.Several authors have described the appearance of psoriatic lesions in patients with asthma or atopic dermatitis following the therapy with dupilumab,a monoclonal antibody that blocks the interleukin(IL)-4,another Th-2 cytokine.CASE SUMMARY We present the case of a 59-year-old patient who developed psoriasiform lesions on the palms after mepolizumab therapy for asthma,for the activation of the parallel cytokine cascade after the blockade of IL-5.We successfully treated the patient with a topical calcipotriol and betamethasone ointment.CONCLUSION We should investigate with further attention the possible impact on the human immunological ecosystem put in place by the inhibition of the activity of individual inflammatory mediators,so as to be able to recognize the initial adverse effects early.
