METHODS:Forty Sprague-Dawley rats were randomly divided into four groups, and administered distilled water, XYAS and its two different disassembly prescriptions by gavage respectively. Four types of drug-containing serums corresponding to the four groups were then prepared. Tumor necrosis factor(TNF)-α stimulated Ha Ca T was used to establish a psoriasis cell model, and the serums and the retinoid related orphan receptor alpha(RORα) inverse agonist were used respectively to intervene in the model. Enzyme-linked immunosorbent assay was used to detect the levels of interleukin(IL)-6 and melatonin in each group;flow cytometry was used to detect the levels of reactive oxygen species(ROS), mitochondrial membrane potential, and apoptosis;Western blot was used to evaluate the levels of superoxide dismutase 2(SOD2), cytochrome-c(Cyt-c), inhibitor of kappa-B alpha(IκBα), p65 and phosphorylated p65. RESULTS:XYAS and its disassembly prescriptions inhibited the secretion of inflammatory factors such as IL-6, reduced the ROS content and Cyt-c expression, increased the mitochondrial membrane potential and SOD2 content, promoted the apoptosis in Ha Ca T cells and inhibited the activation of the NF-κB pathway. XYAS was also found increase the melatonin content. The above effects are beneficial in the treatment of psoriasis combined with sleep disorders. Meanwhile, XYAS no longer had a significant ameliorative effect after applying the RORα inverse agonist, suggesting that the therapeutic effect of XYAS is related to RORα. CONCLUSIONS:The results of this study confirm that XYAS can be utilized for the treatment of psoriasis combined with sleep disorders via inhibiting the NF-κB pathway, anti-inflammatory, antioxidant and proapoptotic, which is in part related to the regulatory role of melatonin and its receptor RORα.展开更多

Despite advances in systemic treatments, the management of EP remains challenging, particularly in patients with comorbidities or contraindications to standard therapies. Objectives: To evaluate the effectiveness of ozonated water as an adjunctive treatment for EP, delivered using a patented robotic therapy system designed for hygiene and infection prevention in non-self-sufficient patients. Methods: We report the case of a 90-year-old male patient with acute EP who received daily skin treatments with ozonated water in conjunction with supportive care, including rehydration and antibiotics. The intervention was facilitated by the robotic system “COPERNICO Surveillance & Prevention,” which ensured standardized hygiene practices and clinical documentation. Results: Within one week of treatment, the patient showed complete desquamation of necrotic skin, resolution of erythema, and significant metabolic recovery. Fever subsided, renal function improved, and the patient was discharged in stable condition. Follow-up confirmed sustained clinical improvement, and no adverse events were reported. Conclusions: Ozonated water demonstrated efficacy in alleviating the dermatological and systemic manifestations of EP in a high-risk elderly patient. This case highlights the potential of ozone therapy as a safe, cost-effective adjunctive treatment for EP and underscores the utility of robotic systems in managing complex dermatological conditions. Further research is warranted to validate these findings in larger cohorts.展开更多

文摘Objective:Psoriasis is associated with lipid metabolism disorders,but the underlying mechanisms remain unclear.This study aims to investigate the role of trimethylamine Noxide(TMAO)in lipid metabolism dysregulation in psoriasis.Methods:An imiquimod(IMQ)-induced psoriasis-like mouse model was used to assess lipid metabolism parameters,TMAO levels,and liver flavin monooxygenase 3(FMO3)mRNA expression.Blood samples from healthy individuals and psoriatic patients were collected to measure serum TMAO levels and lipid profiles.To clarify the role of TMAO in the lipid metabolism disorder of mice with psoriasis model,exogenous TMAO,choline,or 3,3-dimethyl-1-butanol(DMB)were administered via intraperitoneal injections or diet in IMQ-treated mice.Liver tissues from the mouse models were subjected to RNA sequencing to identify TMAO-regulated signaling pathways.Results:IMQ-induced psoriatic mice exhibited abnormal glucose,insulin,and lipid levels.IMQ treatment also downregulated the hepatic mRNA expression of glucose transporter 2(Glut2)and silence information regulator 1(Sirt1),while upregulating glucose transporter 4(Glut4)and peroxisome proliferator-activated receptor gamma(PPARγ).Elevated serum TMAO levels were observed in both psoriatic patients and IMQ-treated mice.Additionally,liver FMO3 mRNA expression was increased in the psoriatic mouse model.In patients,TMAO levels positively correlated with Psoriasis Area and Severity Index(PASI)scores,serum triglyceride(TG),and total cholesterol(TC)levels.The intraperitoneal injection of TMAO exacerbated lipid dysregulation in IMQ-treated mice.A choline-rich diet further aggravated lipid abnormalities and liver injury in psoriatic mice,whereas DMB treatment alleviated these effects.RNA-Seq analysis demonstrated that TMAO upregulated hepatic microRNA-122(miR-122),which may suppress the expression of gremlin 2(GREM2),thus contributing to lipid metabolism disorder.Conclusion:TMAO may promote lipid metabolism dysregulation in psoriasis by modulating the hepatic miR-122/GREM2 pathway.
文摘BACKGROUND Erythrodermic psoriasis(EP)is a rare and life-threatening form of psoriasis associated with significant morbidity and mortality.Systemic immunosuppre-ssive therapies are often required but may predispose to opportunistic infections.Disseminated herpes simplex virus type-1(HSV-1)is an unusual complication in otherwise immunocompetent patients and has not been reported in association with ixekizumab therapy for EP.CASE SUMMARY We describe a 49-year-old man with longstanding severe plaque psoriasis,liver cirrhosis,and bipolar disorder who developed EP involving>90%of body surface area[Psoriasis Area and Severity Index(PASI)45].Following initial stabil-ization,he was admitted to the intensive care unit(ICU)with hemodynamic instability,leukocytosis with eosinophilia,and diffuse desquamation.Ixekizumab was initiated with high-dose topical clobetasol.During his ICU stay,he developed recurrent bacteremias and neurologic decline(Glasgow Coma Scale 7/15),fo-llowed by the appearance of widespread vesicles and hemorrhagic crusts.HSV-1 infection was confirmed by polymerase chain reaction(PCR).Immunosuppressive therapy was withheld,and intravenous acyclovir was started,leading to progre-ssive improvement.After ten days,ixekizumab was reintroduced with careful monitoring,resulting in marked clinical improvement(PASI 9.7 at six weeks).The patient remained stable on long-term follow-up with oral acyclovir prophylaxis.CONCLUSION This case highlights the diagnostic and therapeutic challenges of managing EP in the setting of biologic therapy.Disseminated cutaneous HSV-1 should be considered in immunosuppressed patients presenting with new vesicular eruptions,and prompt PCR testing with early antiviral therapy is essential.A multidisciplinary approach is critical to balance immunosuppression for disease control with infection risk.
文摘This review explores the emerging connection between psoriasis and atrial fibrillation(AF),focusing on shared inflammatory mechanisms,clinical implications,and research gaps.Psoriasis,characterized by chronic systemic inflammation,has been associated with increased AF risk,driven by elevated pro-inflammatory cytokines such as interleukin(IL)-6,IL-17,and tumor necrosis factor-alpha.These inflammatory mediators contribute to atrial remodeling,fibrosis,and conduction abnormalities,evidenced by prolonged P-wave dispersion and atrial electromechanical delay in psoriasis patients.Severe psoriasis further exacerbates atrial dysfunction,increasing susceptibility to AF.This review synthesizes existing epidemiological and biological data,highlighting the need for interdisciplinary management of psoriasis patients to mitigate cardiovascular risks.However,the reliance on observational studies limits definitive conclusions about causality.We emphasize the necessity for large-scale,multicenter research to validate these findings,investigate genetic predispositions,and evaluate lifestyle factors and AF burden.Future research should aim to delineate the pathophysiological link between psoriasis and AF.By examining the interplay of systemic inflammation,electrophysiological changes,and clinical outcomes,this review aims to advance understanding of the psoriasis-AF link and guide strategies for early detection,prevention,and management of AF in psoriasis patients.Comprehensive care integrating dermatology and cardiology is essential for improving patient outcomes.

文摘Psoriasis is a chronic inflammatory skin disease,which seriously affects the physical and mental health of patients.The progression of psoriasis is influenced by the excessive production of reactive oxygen species(ROS)and inflammatory responses.In this paper,novel celastrol(Ce)-loaded metal-phenolic nanozymes(tannic acid-Fe^(3+))(TA-Fe)integrated microneedles(Ce@TA-Fe/MNs)were constructed to achieve the combined oxidative stress alleviation and anti-inflammatory therapy of psoriasis.Molecular dynamics simulations and structural characterization confirmed the successful fabrication of nanozymes.The Ce@TA-Fe/MNs system,characterized by its rapid dissolution kinetics and superior mechanical strength,enabled minimally invasive skin penetration for efficient nanozymes delivery.Nanozymes possessed superoxide dismutase and catalase mimetic enzyme activities,effectively eliminating excessive ROS in psoriatic skin lesions.Additionally,the release of Ce from Ce@TA-Fe provided strong antioxidant and anti-inflammatory effects.Based on these characteristics,Ce@TA-Fe/MNs could effectively alleviate the symptoms in psoriasis mice models.These findings demonstrated that the integration of Ce-equipped nanozymes within MNs holds great promise as a therapeutic strategy for the clinical management of psoriasis.
基金National Natural Science Foundation of China:Study on the Mechanism of Cooling Blood and Tranquilizing Mind in the Treatment of Psoriasis with Sleep Disorder based on the Regulation of Oxidative Stress by Melatonin (No. 82074436)。
文摘OBJECTIVE:To explore the therapeutic mechanisms of Xiaoyin Anshen Yin( 消银安神饮, XYAS) in treating psoriasis associated with sleep focusing on melatonin and the regulation of the nuclear factor kappa-B(NF-κB) pathway. METHODS:Forty Sprague-Dawley rats were randomly divided into four groups, and administered distilled water, XYAS and its two different disassembly prescriptions by gavage respectively. Four types of drug-containing serums corresponding to the four groups were then prepared. Tumor necrosis factor(TNF)-α stimulated Ha Ca T was used to establish a psoriasis cell model, and the serums and the retinoid related orphan receptor alpha(RORα) inverse agonist were used respectively to intervene in the model. Enzyme-linked immunosorbent assay was used to detect the levels of interleukin(IL)-6 and melatonin in each group;flow cytometry was used to detect the levels of reactive oxygen species(ROS), mitochondrial membrane potential, and apoptosis;Western blot was used to evaluate the levels of superoxide dismutase 2(SOD2), cytochrome-c(Cyt-c), inhibitor of kappa-B alpha(IκBα), p65 and phosphorylated p65. RESULTS:XYAS and its disassembly prescriptions inhibited the secretion of inflammatory factors such as IL-6, reduced the ROS content and Cyt-c expression, increased the mitochondrial membrane potential and SOD2 content, promoted the apoptosis in Ha Ca T cells and inhibited the activation of the NF-κB pathway. XYAS was also found increase the melatonin content. The above effects are beneficial in the treatment of psoriasis combined with sleep disorders. Meanwhile, XYAS no longer had a significant ameliorative effect after applying the RORα inverse agonist, suggesting that the therapeutic effect of XYAS is related to RORα. CONCLUSIONS:The results of this study confirm that XYAS can be utilized for the treatment of psoriasis combined with sleep disorders via inhibiting the NF-κB pathway, anti-inflammatory, antioxidant and proapoptotic, which is in part related to the regulatory role of melatonin and its receptor RORα.
文摘BACKGROUND Psoriasis is a chronic inflammatory condition related to an increased athero-sclerotic cardiovascular disease(ASCVD)risk.AIM To investigate whether lipoprotein(a)[Lp(a)]levels are increased in patients with psoriasis.METHODS A comprehensive literature search up to January 30,2025 was conducted utilizing PubMed and Cochrane Library databases.A qualitative synthesis and a meta-analysis on Lp(a)mean differences(MD)between psoriasis cases and healthy controls(HC)was performed.The protocol of this meta-analysis has been re-gistered to PROSPERO(No.CRD420250652465).RESULTS Eighteen studies with 1650 psoriasis patients and 1621 HC were eligible for qua-litative synthesis.Pooled analysis from 16 studies(1401 psoriasis patients and 1320 HC)demonstrated that psoriasis patients had significantly higher Lp(a)levels compared with the HC group(MD:6.72 mg/dL,95%CI:4.32-9.12,P<0.00001,I2=71%).Sensitivity analyses according to the region of origin was also performed.The pooled analysis of the European sub-population showed a pronounced increase in Lp(a)levels in 189 patients with psoriasis vs 178 HC(MD:15.86 mg/dL,95%CI:5.79-25.92,P<0.002,I2=79%),while the pooled analysis on the Asian sub-population demonstrated a smaller but still significant difference in Lp(a)levels between 1177 psoriasis patients and 1127 HC(MD:4.95 mg/dL,95%CI:2.99-6.92,P<0.00001,I2=58%).CONCLUSION Our findings suggest that Lp(a)levels are significantly elevated in psoriasis patients,further adding to their ASCVD risk.
文摘BACKGROUND Psoriasis is often first recognized by patients through online image searches.However,search engine algorithms influenced by geographic location may still produce results that predominantly feature lighter skin tones,regardless of the region’s majority skin type.This underrepresentation may limit recognition and delay care for people of color.AIM To examine whether search algorithms tailor region-specific results in terms of skin color for psoriasis imagery.METHODS This observational study recruited 66 participants from 18 countries who conducted image searches for“psoriasis”across various web browsers.During the meeting,a Google form was posted to record observations,and participants reported the diversity of skin tones in the first three rows of search results using a reference image depicting Fitzpatrick types.RESULTS Results showed a global bias toward lighter skin tones,with 94%of participants identifying light skin predominance in the first row and minimal representation of medium or darker skin tones in subsequent results,verified via χ^(2) analysis.Participants who observed darker or mixed skin tones typically found them further down their results.CONCLUSION There remains a significant gap in global representation of psoriasis imagery.This paper deepens the current understanding of bias in online media and pushes for further exploration of more inclusive dermatologic imagery.
文摘Psoriasis is a prevalent inflammatory disease that shares chronic inflammation pathways with the pathophysiology of metabolic syndrome(MetS),type-2 diabetes mellitus and atherosclerosis.A high prevalence of steatosis and advanced liver fibrosis has been described in psoriasis.The influence of MetS and its compounds,patatin-like phospholipase domain containing 3 and transmembrane 6 superfamily member 2 gene polymorphisms and the cumulative dose of methotrexate(MTX)in the progression of steatotic disease are still under debate.A suitable new classification for psoriasis-related liver disease,under the umbrella of steatotic liver disease(SLD),might be evaluated due to the potential impact of MTX on liver steatosis.Considering the interplay between the MetS,steatosis and MTX,a new definition for this complex disease might be discussed since it is not entirely addressed under the umbrella of SLD and metabolic-dysfunction associated SLD.Hence,shortly,a discussion could be raised on the feasible term“Met-Drug SLD”,metabolic and drug-induced SLD,which comprises both metabolic dysfunction and drug-related SLD.This review aims to report the best evidence to accurately classify liver disease in psoriasis,considering the new definition of SLD,allowing appropriate management once it is carefully defined.
文摘Background: Erythrodermic psoriasis (EP) is a rare, severe variant of psoriasis characterized by widespread erythema, scaling, and systemic complications. Despite advances in systemic treatments, the management of EP remains challenging, particularly in patients with comorbidities or contraindications to standard therapies. Objectives: To evaluate the effectiveness of ozonated water as an adjunctive treatment for EP, delivered using a patented robotic therapy system designed for hygiene and infection prevention in non-self-sufficient patients. Methods: We report the case of a 90-year-old male patient with acute EP who received daily skin treatments with ozonated water in conjunction with supportive care, including rehydration and antibiotics. The intervention was facilitated by the robotic system “COPERNICO Surveillance & Prevention,” which ensured standardized hygiene practices and clinical documentation. Results: Within one week of treatment, the patient showed complete desquamation of necrotic skin, resolution of erythema, and significant metabolic recovery. Fever subsided, renal function improved, and the patient was discharged in stable condition. Follow-up confirmed sustained clinical improvement, and no adverse events were reported. Conclusions: Ozonated water demonstrated efficacy in alleviating the dermatological and systemic manifestations of EP in a high-risk elderly patient. This case highlights the potential of ozone therapy as a safe, cost-effective adjunctive treatment for EP and underscores the utility of robotic systems in managing complex dermatological conditions. Further research is warranted to validate these findings in larger cohorts.

文摘This research aimed to identify and validate ferroptosis-related signature genes associated with psoriasis through a comprehensive bioinformatics approach,while also predicting potential traditional Chinese medicines(TCMs)targeting these genes.The findings might offer a foundation for understanding ferroptosis mechanisms in psoriasis and exploring TCM-based therapeutic strategies.To begin,we retrieved gene expression profile data from psoriasis patients and healthy controls from the Gene Expression Omnibus(GEO)database,followed by data normalization.Ferroptosis-associated differentially expressed genes(Fer-DEGs)were identified using the FerrDb database.Subsequent GO and KEGG enrichment analyses provided insights into the biological functions and signaling pathways of these Fer-DEGs.Core Fer-DEGs were identified using machine learning algorithms,and their expression levels were further validated with an external dataset to evaluate diagnostic potential.Additionally,the symMap database facilitated the reverse prediction of TCMs targeting these key signature genes.The analysis identified 265 significant Fer-DEGs.GO enrichment indicated their involvement in diverse biological processes,while KEGG analysis highlighted their roles in various pathways,including ferroptosis,autophagy,cancer,infection,and metabolism,as well as PI3K-Akt,FoxO,mTOR,and HIF-1 signaling pathways.Machine learning pinpointed nine core psoriasis-related Fer-DEGs:PRKAA2,ANO6,POR,PTEN,MAPK8,ZFAS1,ADAM23,TMBIM4,and PARP14,all demonstrating strong diagnostic performance.Predicted TCMs primarily included those with heat-clearing,detoxifying,blood-activating,stasis-resolving,and phlegm-resolving properties.In conclusion,our study suggested that PRKAA2,ANO6,POR,PTEN,MAPK8,ZFAS1,ADAM23,TMBIM4,and PARP14 were key players in the ferroptosis pathway in psoriasis.TCMs with properties such as heat-clearing,blood activation,and phlegm resolution might hold promise for anti-ferroptosis interventions in psoriasis treatment.
