ABSTRACT

OBJECTIVE@#To determine the role of Tripterygium wilfordii multiglycoside (TGW) in the treatment of psoriatic dermatitis from a cellular immunological perspective.@*METHODS@#Mouse models of psoriatic dermatitis were established by imiquimod (IMQ). Twelve male BALB/c mice were assigned to IMQ or IMQ+TGW groups according to a random number table. Histopathological changes in vivo were assessed by hematoxylin and eosin staining. Ratios of immune cells and cytokines in mice, as well as PAM212 cell proliferation in vitro were assessed by flow cytometry. Pro-inflammatory cytokine expression was determined using reverse transcription quantitative polymerase chain reaction.@*RESULTS@#TGW significantly ameliorated the severity of IMQ-induced psoriasis-like mouse skin lesions and restrained the activation of CD45+ cells, neutrophils and T lymphocytes (all P<0.01). Moreover, TGW significantly attenuated keratinocytes (KCs) proliferation and downregulated the mRNA levels of inflammatory cytokines including interleukin (IL)-17A, IL-23, tumor necrosis factor α, and chemokine (C-X-C motif) ligand 1 (P<0.01 or P<0.05). Furthermore, it reduced the number of γ δ T17 cells in skin lesion of mice and draining lymph nodes (P<0.01).@*CONCLUSIONS@#TGW improved psoriasis-like inflammation by inhibiting KCs proliferation, as well as the associated immune cells and cytokine expression. It inhibited IL-17 secretion from γ δ T cells, which improved the immune-inflammatory microenvironment of psoriasis.

ABSTRACT

Psoríase é uma dermatose de caráter inflamatório ligado a diversas composições do ser, sendo estas a genética, o sistema imune, o ambiente e o estado mental do paciente, apresentando evidências de ser um quadro clínico multifacetado. A composição da medicina psicossomática empenha-se na relação mental e emocional e do corpo, sendo importante mostrar a relação desta com a psoríase. Por isso, busca-se avaliar as evidências disponíveis na literatura sobre a relação entre a psoríase e os aspectos psicossomáticos. Foi realizado uma a revisão de literatura, por meio de seleção de artigos das base de dados Medical Literature Analysis and Retrieval System Online (PubMed/Medline), biblioteca virtual em saúde Scientific Electronic Library Online (SciElo), UpToDate e Google acadêmico. A busca por artigos científicos resultou em 20 artigos selecionados. Foi possível concluir, que há estudos fundamentados correlacionando a medicina psicossomática e a psoríase, além de que diversos fatores que afetam a homeostase corporal, provocam alterações nervosas, e consequentemente afetam as células da pele. Além disso, foi encontrado evidências que a estigmatização que os pacientes sofrem influenciam no aumento da gravidade da doença, sendo necessário a realização de um tratamento psico cognitivo-comportamental juntamente com o tratamento dos sinais e sintomas gerais da doença. Desta forma, o presente trabalho pôde olhar para a patologia com um olhar ampliado relacionado ao aspecto mental e emocional o que promove melhor compreensão e as consequências disto são a maior capacidade de intervenção sobre a psoríase.


Psoriasis is an inflammatory dermatosis linked to several compositions of the being, which are genetics, the immune system, the environment and the patient's mental state, that is, it shows evidence of being a multifaceted clinical picture. Since the composition of psychosomatic medicine is committed to the relationship between the mental, emotional, and body, it is important to show its relationship with psoriasis. Therefore, we sought to evaluate the available evidence in the literature on the relationship between psoriasis and psychosomatic aspects. A literature review was conducted by selecting articles from the Medical Literature Analysis and Retrieval System Online (PubMed/Medline), Scientific Electronic Library Online (SciElo), UpToDate and Google Scholar databases. The search for scientific articles resulted in 20 selected articles. It was possible to conclude that there are well-founded studies correlating psychosomatic medicine and psoriasis, and that several factors that affect the body's homeostasis cause nervous alterations, and consequently affect the skin cells. Moreover, it was found evidence that the stigmatization that patients suffer influences the increase of the severity of the disease, being necessary the realization of a psycho cognitive-behavioral treatment along with the treatment of the general signs and symptoms of the disease. Thus, the present work could look at the pathology with a broader view related to the mental and emotional aspect, which promotes better understanding and the consequences of this are a greater ability to intervene on psoriasis.


La psoriasis es una dermatosis inflamatoria vinculada a varias composiciones del ser, que son la genética, el sistema inmunitario, el medio ambiente y el estado mental del paciente, es decir, muestra evidencias de ser un cuadro clínico multifacético. Dado que la composición de la medicina psicosomática está comprometida con la relación entre lo mental, lo emocional y el cuerpo, es importante mostrar su relación con la psoriasis. Por lo tanto, se buscó evaluar la evidencia disponible en la literatura sobre la relación entre la psoriasis y los aspectos psicosomáticos. Se realizó una revisión bibliográfica seleccionando artículos de las bases de datos Medical Literature Analysis and Retrieval System Online (PubMed/Medline), Scientific Electronic Library Online (SciElo), UpToDate y Google Scholar. La búsqueda de artículos científicos dio como resultado 20 artículos seleccionados. Se pudo concluir que existen estudios bien fundamentados que correlacionan la medicina psicosomática y la psoriasis, y que diversos factores que afectan a la homeostasis del organismo provocan alteraciones nerviosas y, en consecuencia, afectan a las células de la piel. Además, se encontraron evidencias de que la estigmatización que sufren los pacientes influye en el aumento de la gravedad de la enfermedad, siendo necesaria la realización de un tratamiento psico cognitivo- conductual junto con el tratamiento de los signos y síntomas generales de la enfermedad. Así, el presente trabajo pudo contemplar la patología con una visión más amplia relacionada con el aspecto mental y emocional, lo que favorece una mejor comprensión y las consecuencias de ello son una mayor capacidad de intervención sobre la psoriasis.

ABSTRACT

Introducción: La psoriasis es una enfermedad crónica con diversas manifestaciones cutáneas que presenta asociación con patologías cardiovasculares y reumatológicas y que puede requerir manejo hospitalizado. El objetivo de este estudio fue describir la tasa de egresos hospitalarios por psoriasis entre los años 2018-2021 en Chile. Metodología: Estudio descriptivo observacional, sobre egresos hospitalarios por psoriasis entre 2018-2021, Chile, según sexo y grupos etario (n=2463). Datos obtenidos del Departamento de estadística e información de Salud. Se calculó la Tasa de egreso hospitalario (TEH). No se requirió comité de ética. Resultados: El año 2020 y 2021 se presentó la menor TEH del periodo de estudio con 2.8 y 2.09/100.000 hab respectivamente. El sexo masculino presento la mayor TEH del periodo con 4.96, y el grupo etario de 45-64 años presento la mayor TEH con 6.97/100000 habitantes. Discusión: En el año 2020 y 2021 se evidenció una reducción de la tasa de egreso hospitalario, que coincide con la declaración de pandemia en el año 2020 producto del virus SARS-CoV-2 y esto puede deberse a una reconversión de camas, a camas respiratorias. El sexo femenino podría presentar menor TEH debido a que el estrógeno se reporta como un factor protector. La mayor TEH en el grupo etario 45-64 puede explicarse debido a que esta población presenta más comorbilidades que predisponen a la psoriasis. Conclusión: Se requieren más estudios a nivel nacional para profundizar en los resultados encontrados. Existe escasez de estadísticas nacionales de tasa de egreso de psoriasis siendo interesante aumentar el periodo de tiempo estudiado para profundizar los hallazgos reportados.


Introduction: Psoriasis is a chronic disease with a diversity of skin manifestations, whose etiology is multifactorial and associated with cardiovascular and rheumatological pathologies and that may require hospitalization. The objective of this study was to describe the rate of hospital discharges due to psoriasis between the years 2018-2021 in Chile. Methodology: Observational descriptive study on hospital discharges for psoriasis between 2018-2021 in Chile according to sex and age groups (n=2463).. The data was obtained from the Department of Statistics and Health Information (DEIS). The Hospital Discharge Rate (TEH) was calculated. No ethics committee was required. Results: The year 2020 and 2021 presented the lowest TEH of the study period with 2.8 and 2.09/100,000 habitants respectively. The male sex presented the highest TEH of the period with 4.96, and the age group of 45-64 years presented the highest TEH with 6.97/100,000 habitants. Discussion: In 2020 and 2021, there was a reduction in the hospital discharge rate, which coincides with the declaration of a pandemic in 2020 as a result of the SARS-CoV-2 virus and this may be due to a conversion of beds to respiratory beds. The female sex could present lower TEH because estrogen is reported as a protective factor. The higher TEH in the 45-64 age group can be explained by the fact that this population presents more comorbidities that predispose to psoriasis. Conclusion: More studies are required at a national level to deepen the results found. There is a scarcity of national statistics on the rate of discharge from psoriasis, and it is interesting to increase the period of time studied to deepen the reported findings.

ABSTRACT

Total glucosides of Rhizoma Smilacis Glabrae (RSG) are selective immunosuppressants that exhibit primary efficacy in the treatment of rheumatoid arthritis through targeted inhibition of activated T cells. In this study, we aimed to investigate the potential application of RSG in the treatment of psoriasis and elucidate its mechanism of action and material basis. Our findings revealed significant improvements upon administration of RSG in an imiquimod (IMQ)-induced psoriasis model. These improvements were characterized by a remarkable increase in the number of tail scales in mice and a substantial amelioration of skin erythema, ulceration, and flaking. By transcriptome sequencing and T-cell flow sorting assay, we identified notable effects of RSG on the modulation of various cellular processes. Specifically, RSG prominently down-regulated the Th17/Treg ratio in damaged skin tissues and reduced the proportion of G2 phase cells. Furthermore, RSG exhibited a stimulatory effect on the proliferation and differentiation of epithelial cells. Of particular interest, we discovered that β-sitosterol, sitostenone, stigmasterol, smiglanin, and cinchonain Ib displayed potent inhibitory effects on the IL-17-mediated inflammatory response in HaCaT cells. In summary, our study highlights the therapeutic potential of RSG in the treatment of psoriasis, attributed to its ability to regulate the Th17/Treg balance. These findings contribute to the development of new indications for RSG and provide a solid theoretical foundation for further exploration in this field.

ABSTRACT

OBJECTIVE@#To explore whether the ethanol extract of Herpetospermum caudigerum Wall (EHC), a Xizang medicinal plant traditionally used for treating liver diseases, can improve imiquimod-induced psoriasis-like skin inflammation.@*METHODS@#Immunohistochemistry and immunofluorescence staining were used to determine the effects of topical EHC use in vivo on the skin pathology of imiquimod-induced psoriasis in mice. The protein levels of interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), and interleukin-17A (IL-17A) in mouse skin samples were examined using immunohistochemical staining. In vitro, IFN-γ-induced HaCaT cells with or without EHC treatment were used to evaluate the expression of keratinocyte-derived intercellular cell adhesion molecule-1 (ICAM-1) and chemokine CXC ligand 9 (CXCL9) using Western blotting and reverse transcription-quantitative polymerase chain reaction. The protein synthesis inhibitor cycloheximide and proteasome inhibitor MG132 were utilized to validate the EHC-mediated mechanism underlying degradation of ICAM-1 and CXCL9.@*RESULTS@#EHC improved inflammation in the imiquimod-induced psoriasis mouse model and reduced the levels of IFN-γ, TNF-α, and IL-17A in psoriatic lesions. Treatment with EHC also suppressed ICAM-1 and CXCL9 in epidermal keratinocytes. Further mechanistic studies revealed that EHC suppressed keratinocyte-derived ICAM-1 and CXCL9 by promoting ubiquitin-proteasome-mediated protein degradation rather than transcriptional repression. Seven primary compounds including ehletianol C, dehydrodiconiferyl alcohol, herpetrione, herpetin, herpetotriol, herpetetrone and herpetetrol were identified from the EHC using ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometry.@*CONCLUSION@#Topical application of EHC ameliorates psoriasis-like skin symptoms and improves the inflammation at the lesion sites.

ABSTRACT

OBJECTIVE@#To observe the clinical efficacy of moxibustion combined with coptis chinensis ointment sealing on plaque psoriasis complicated with obesity.@*METHODS@#A total of 52 patients of plaque psoriasis complicated with obesity were randomized into an observation group (26 cases) and a control group (26 cases, 2 cases dropped off). Coptis chinensis ointment sealing was adopted in the control group. On the basis of the treatment in the control group, moxibustion was applied at ashi point (area of local target lesions), Zhongwan (CV 12) and bilateral Zusanli (ST 36), Fenglong (ST 40), Quchi (LI 11), Tianshu (ST 25), Shangjuxu (ST 37) in the observation group. The treatment was given 30 min each time, once a day for 4 weeks in both groups. The psoriasis area and severity index (PASI) score, obesity related indexes (body mass, waist circumference, body mass index [BMI]), triglyceride, cholesterol, uric acid and plasma glucose were compared before and after treatment, and the clinical efficacy was evaluated in the two groups.@*RESULTS@#After treatment, the PASI scores were decreased compared with those before treatment in the two groups (P<0.01), and the PASI score in the observation group was lower than that in the control group (P<0.05); the body mass, waist circumference, BMI, triglyceride, cholesterol, uric acid and plasma glucose were decreased compared with those before treatment in the observation group (P<0.01, P<0.05), the triglyceride and cholesterol in the observation group were lower than those in the control group (P<0.05). The total effective rate was 53.8% (14/26) in the observation group, which was superior to 20.8% (5/24) in the control group (P<0.05).@*CONCLUSION@#Moxibustion combined with coptis chinensis ointment sealing can effectively improve the clinical symptoms in patients of plaque psoriasis complicated with obesity.

ABSTRACT

Autoimmune-related skin diseases are a group of disorders with diverse etiology and pathophysiology involved in autoimmunity. Genetics and environmental factors may contribute to the development of these autoimmune disorders. Although the etiology and pathogenesis of these disorders are poorly understood, environmental variables that induce aberrant epigenetic regulations may provide some insights. Epigenetics is the study of heritable mechanisms that regulate gene expression without changing DNA sequences. The most important epigenetic mechanisms are DNA methylation, histone modification, and noncoding RNAs. In this review, we discuss the most recent findings regarding the function of epigenetic mechanisms in autoimmune-related skin disorders, including systemic lupus erythematosus, bullous skin diseases, psoriasis, and systemic sclerosis. These findings will expand our understanding and highlight the possible clinical applications of precision epigenetics approaches.

ABSTRACT

Psoriasis is a chronic skin disease and an important health concern. Western medicine and therapies are the main treatment strategies for psoriasis vulgaris (PV); however, the overall prognosis of patients with PV is still poor. Therefore, PV prevention is especially crucial. Chinese medicine (CM) has a long history of treating psoriasis, and it has unique wisdom in different cognitive angles and treatment modes from modern medicine. In this review, we first summarized the herbs and ancient CM formulas that have therapeutic effects on PV. Second, the research status and obstacles to the current development of CM in modern medicine were reviewed. Finally, the future of CM in the context of precision medicine and integrated medicine was discussed. After a detailed reading of the abundant literature, we believe that CM, through thousands of years of continuous development and clinical practice, has achieved high effectiveness and safety for PV treatment, despite its surrounding controversy. Moreover, precise analyses and systematic research methods have provided new approaches for the modernization of CM in the future. The treatment of PV with CM is worth popularizing, and we hope it can benefit more patients.

ABSTRACT

OBJECTIVE@#To examine data from studies supporting the clinical efficacy of medical approaches from India traditional systems of medicines like Ayurveda, Unani, Siddha, and Homeopathy for psoriasis using outcome indicators employed in clinical practice and research.@*METHODS@#Searches were conducted between December 2019 and September 2020 in databases PubMed, Scopus, Web of Science and Ovid Medline using search terms including traditional, complementary, psoriasis, Kushtha, Ayurveda, Siddha, Unani, Homeopathy and clinical. Controlled trials, case series and case reports published from India were included.@*RESULTS@#Data of 17 selected studies were extracted. Treatment efficacy in terms of improvement in Psoriasis Area and Severity Index (PASI) score or/and percentage reduction in score (PASI 50, PASI 75 and PASI 90) or/and patient-reported outcomes using instruments like Dermatology Life Quality Index and Psoriasis Disability Index were noted. All studies reported good improvement as per the study specific outcome. However, study characteristics, including study design, sample size, follow-up period, inclusion and exclusion criteria were heterogeneous, and the choice of outcome measures was not adequate to conclude the effectiveness of intervention. The use of some herbs as common ingredients in several formulations across different systems of medicines were noted in analyzing individual formulation.@*CONCLUSIONS@#Future studies must incorporate a comprehensive study design with specific outcome measures like PASI, PASI 75, PASI 90, quality of life parameters, compliance to medications, adverse reactions, remission period, relapse rate and cost-effectiveness with long term follow-up. The currently available evidence on the roles of these herbs at molecular level in psoriasis is preliminary.

ABSTRACT

OBJECTIVE@#To investigate the therapeutic effects of total glucosides of paeony (TGP) on psoriasis based on the immunomodulatory effect of dermal mesenchymal stem cells (DMSCs).@*METHODS@#A total of 30 male BALB/c mice were divided into 6 groups (n=5 in each) by a random number table method, including control, psoriasis model (model, 5% imiquimod cream 42 mg/d), low-, medium- and high-dose TGP (50, 100, and 200 mg/kg, L, M-, and H-TGP, respectively), and positive control group (2.5 mg/kg acitretin). After 14 days of continuous administration, the skin's histopathological changes, apoptosis, secretion of inflammatory cytokines, and proportion of regulatory T cells (Treg) and T helper cell 17 (Th17) were evaluated using hematoxylin-eosin (HE) staining, TdT-mediated dUTP nick end labeling staining, enzyme-linked immunosorbent assay, and flow cytometry, respectively. DMSCs were further isolated from the skin tissues of normal and psoriatic mice, and the cell morphology, phenotype, and cycle were observed. Furthermore, TGP was used to treat psoriatic DMSCs to analyze the effects on the DMSCs immune regulation.@*RESULTS@#TGP alleviated skin pathological injury, reduced epidermis layer thickness, inhibited apoptosis, and regulated the secretion of inflammatory cytokines and the proportion of Treg and Th17 in the skin tissues of psoriatic mice (P<0.05 or P<0.01). There was no significant difference in cell morphology and phenotype between control and psoriatic DMSCs (P>0.05), however, more psoriatic DMSCs remained in G0/G1 phase compared with the normal DMSCs (P<0.01). TGP treatment of psoriatic DMSCs significantly increased cell viability, decreased apoptosis, relieved inflammatory response, and inhibited the expression of toll-like receptor 4 and P65 (P<0.05 or P<0.01).@*CONCLUSION@#TGP may exert a good therapeutic effect on psoriasis by regulating the immune imbalance of DMSCs.

ABSTRACT

This study aimed to investigate the development status of traditional Chinese medicine(TCM) intervention in psoriasis in recent ten years, analyze the research hotspots, and summarize the development trends to provide reference materials for scholars in this field. Taking the available literature related to the field of TCM intervention in psoriasis as the research object, the trends, contents, and source publications were statistically analyzed based on bibliometrics. The research cooperation and co-occurrence of keywords in this field were studied by the knowledge map analysis method based on CiteSpace. The total number of Chinese papers was 2 993 and English papers 285. In terms of publication trend, the annual publication of English papers was low but showed an obvious upward trend, while the increase in Chinese papers fluctuated and tended to be flat. In terms of the content of Chinese papers published, TCM ranked first according to the discipline(2 415). In English papers, the number of publications in pharmacology and pharmaceutical science was the highest(87). Literature source analysis showed that the Chinese and English journals with the most publications were China Journal of Traditional Chinese Medicine and Pharmacy and Evidence Based Complementary and Alternative Medicine, respectively. Beijing University of Chinese Medicine published the most dissertations in China(99). The authors with the most publications in Chinese and English were LI Bin(Yueyang Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Shanghai University of Traditional Chinese Medicine) and LU Chuan-jian(Guangdong Hospital of Traditional Chinese Medicine). As revealed by the CiteSpace analysis of the research cooperation network, there were four mature and stable core teams in this field, but the cooperation intensity between different teams was weak. According to the keywords co-occurrence knowledge graph constructed by CiteSpace, the current hot keywords in this field are as follows: psoriasis, blood-heat syndrome, blood-stasis syndrome, fire needle, blood-dryness type, imiquimod, TCM bath, etiology and pathogenesis, cytokines, cupping therapy, etc. In summary, Chinese scholars have conducted active exploration and research in the field of TCM intervention in psoriasis in recent ten years. The overall development trend is good, and the breadth and depth of the research are constantly extending. It is suggested that relevant research should be free from discipline restrictions and strive for interdisciplinary integration.

ABSTRACT

BACKGROUND@#Reports on the prevalence of psoriatic arthritis (PsA) among Chinese patients with psoriasis are very limited. This study, conducted by rheumatologists, estimated the prevalence of PsA in a large number of Chinese patients with psoriasis.@*METHODS@#Consecutive patients with a confirmed diagnosis of psoriasis attending nine dermatology clinics in five hospitals were recruited. All psoriasis patients were asked to complete a questionnaire comprising 16 questions to identify possible cases of PsA. All patients with one or more positive answers to the questionnaire were evaluated by two experienced rheumatologists.@*RESULTS@#A total of 2434 psoriasis patients, including 1561 males and 873 females, were enrolled. Both the questionnaire and rheumatologists' examinations were completed in the dermatology clinics. The results identified 252 patients with PsA, comprising 168 males and 84 females. The overall prevalence of PsA among psoriasis patients was 10.4% (95% confidence interval [95% CI], 9.1%-11.7%). By sex, the prevalence was 10.8% (95% CI, 9.2%-12.5%) for males and 9.6% (95% CI, 7.7%-11.9%) for females and there was no significant sex difference in the prevalence of PsA (P = 0.38). Of the 252 PsA patients, 125 (49.6%, 95% CI, 41.3%-59.1%) were newly diagnosed by rheumatologists. Consequently, the prevalence of undiagnosed PsA among psoriasis patients was 5.2% (95% CI, 4.4%-6.2%).@*CONCLUSION@#The prevalence of PsA in the Chinese population with psoriasis is about 10.4%, which is almost double that of previous reports in the Chinese population, but lower than that in Caucasians.

ABSTRACT

Psoriasis is a chronic inflammatory skin disease with significant physical and psychological burdens. The interplay between the innate and adaptive immune systems is thought to contribute to the pathogenesis; however, the details of the pathogenesis remain unclear. In addition, reliable biomarkers for diagnosis, assessment of disease activity, and monitoring of therapeutic response are limited. Metabolomics is an emerging science that can be used to identify and analyze low molecular weight molecules in biological systems. During the past decade, metabolomics has been widely used in psoriasis research, and substantial progress has been made. This review summarizes and discusses studies that applied metabolomics to psoriatic disease. These studies have identified dysregulation of amino acids, carnitines, fatty acids, lipids, and carbohydrates in psoriasis. The results from these studies have advanced our understanding of: (1) the molecular mechanisms of psoriasis pathogenesis; (2) diagnosis of psoriasis and assessment of disease activity; (3) the mechanism of treatment and how to monitor treatment response; and (4) the link between psoriasis and comorbid diseases. We discuss common research strategies and progress in the application of metabolomics to psoriasis, as well as emerging trends and future directions.

ABSTRACT

INTRODUCTION@#Ustekinumab is a human monoclonal antibody that binds to the p40 subunit of both interleukin (IL)-12 and IL-23, and it is approved for the treatment of moderate to severe plaque psoriasis. In this study, we assessed the efficacy and safety of patients receiving ustekinumab for psoriasis.@*METHODS@#This retrospective study included all adults with chronic plaque psoriasis who were prescribed ustekinumab in a tertiary dermatologic centre between December 2009 and December 2015. Efficacy end points included a proportion of patients achieving at least 50% and 75% improvement from baseline psoriasis area and severity index (PASI) and body surface area (BSA) at Weeks 4 and 16.@*RESULTS@#A total of 99 patients were prescribed ustekinumab; 69% of these were Chinese, followed by 15% Indians and 9% Malays. 31 patients had documented PASI scores and 55 patients had documented BSA improvements. In patients with recorded PASI scores, 29 (93.5%) of 31 patients achieved PASI 50, and 21 (67.7%) of 31 achieved PASI 75 at week 16. In patients with recorded BSA, 43 (78.2%) of 55 had at least 50% BSA improvement, and 31 (56.4%) of 55 achieved 75% BSA improvement at 16 weeks. Regarding safety, no patient experienced tuberculosis reactivation. A total of 11 (11%) of 99 patients had latent tuberculosis infection and were treated with prophylactic isoniazid. No patient experienced serious adverse events.

ABSTRACT

Introduction: Inverse psoriasis affects the skin of flexural areas, such as the groin, axillae, umbilicus, intergluteal fold, and external genitalia. Clinical Case: We herein report the case of a man who presented with anal pruritus and, upon physical examination, a perianal dermatosis was found, which was characterized by erythematous plaques, with fine scaling. The case was initially managed with zinc oxide, and when no improvement was observed, we decided to take an incisional biopsy, which indicated histological changes suggestive of psoriasiform dermatitis. Discussion: Inverse psoriasis affects 3% to 7% of patients with psoriasis, and it manifests with erythematous plaques without the classic scaling appearance. The skin in these areas is susceptible to maceration, irritation, and ulceration, which alter the classic clinical picture. It may present with typical lesions or, less frequently, in isolation in the anogenital region. In the anogenital presentation only, the diagnosis should be made by biopsy, looking for the classic histopathological features of psoriasis. As for the first-line treatment, low- or medium-potency topical steroids are used for short periods of time; the second-line treatment is with emollients and tar-based products; and the third-line treatment uses an immunomodulator. Conclusion: This presentation is infrequent, and it requires a high index of suspicion for the diagnosis, always supported by biopsies, in search of the classic histopathological features of psoriasis.

ABSTRACT

Psoriasis is an autoimmune disease that courses with chronic inflammation of the skin and exaggerated growth of keratinocytes, with a decrease in life expectancy mainly due to cardiovascular diseases. However, cardiometabolic conditions are poorly investigated. The objective of this study was to verify the relationship between psoriasis and cardiovascular diseases, seeking to answer: "What is the relationship between chronic inflammation present in psoriasis and cardiovascular diseases?" It is an integrative review using the PubMed platform and the descriptors "Psoriasis", "Cardiovascular diseases" and "Risk factors", with the boolean "AND." Was obtained 72 articles that, after analysis and exclusion, resulted in 12 publications. In conclusion, there was a relationship between several metabolic cytokines and those involved in the pathophysiology of psoriasis, directly associated with increased cardiovascular risks, due to chronic inflammation.


Psoríase é doença autoimune que cursa com inflamação crônica da pele e crescimento exagerado de queratinócitos, tendo a diminuição da expectativa de vida principalmente por doenças cardiovasculares. Contudo, as condições cardiometabólicas são pouco investigadas. O objetivo deste estudo foi verificar a relação entre a psoríase e as doenças cardiovasculares procurando responder: "Qual a relação da inflamação crônica presente na psoríase com as doenças cardiovasculares?". É revisão integrativa utilizando a plataforma PubMed e os descritores "Psoríase", "Doenças cardiovasculares" e "Fatores de risco", com o booleano "AND". Obteve-se 72 artigos que, após análise e exclusão, resultaram em 12 publicações. Em conclusão, observou-se relação entre várias citocinas metabólicas e envolvidas na fisiopatologia da psoríase, diretamente associadas ao aumento dos riscos cardiovasculares, devido a um quadro de inflamação crônica.

ABSTRACT

SUMMARY: This study is to investigate the regulation of Notch1 and Foxp1 by miR-34a in the development of psoriasis vulgaris. RT-PCR was used to compare the levels of miR-34a in the skin lesions of 20 patients with psoriasis vulgaris and 20 normal skin tissues. Immunohistochemistry was used to detect the expression of Notch1 and Foxp1 in 51 patients with psoriasis vulgaris, which were further compared with that in 29 normal control tissues. In addition, in HaCaT cells, we used miR-34a mimics and inhibitors to overexpress and inhibit miR-34a, respectively, and detected the mRNA and protein levels of miR-34a, Notch1, and Foxp1. The level of miR-34a in the skin lesions of patients with psoriasis vulgaris was significantly higher than that in normal skin tissues (t=2.192, P<0.05). The positive rate of Notch1 in the skin lesions of patients with psoriasis vulgaris was 76.47 %, which was significantly higher than that in normal skin tissues (13.79 %) (t=29.215, P<0.01). The positive rate of FOXP1 in the psoriasis vulgaris group was 92.16 %, which was also significantly higher than that in the normal skin group (65.52 %) (t=9.087, P<0.01). In addition, overexpression of miR-34a significantly promoted the expression of Notch1 and Foxp1. However, inhibition of miR-34a significantly reduced Notch1 and Foxp1 levels. miR- 34a is highly expressed in the skin tissues of patients with psoriasis vulgaris, and may participate in the development of psoriasis vulgaris by regulating Notch1 and Foxp1.


RESUMEN: El objetivo de este estudio fue investigar la regulación de Notch1 y Foxp1 por miR-34a en el desarrollo de la psoriasis vulgar. Se utilizó RT-PCR con el fin de comparar los niveles de miR-34a en las lesiones cutáneas de 20 pacientes con psoriasis vulgar y 20 tejidos de piel normales. Se utilizó inmunohistoquímica para detectar la expresión de Notch1 y Foxp1 en 51 pacientes con psoriasis vulgar, que se compararon además con la de 29 tejidos normales control. Además, en las células HaCaT, usamos miméticos e inhibidores de miR-34a para sobreexpresar e inhibir miR-34a, respectivamente, y detectamos los niveles de ARNm y proteína de miR-34a, Notch1 y Foxp1. El nivel de miR- 34a en las lesiones cutáneas de pacientes con psoriasis vulgar fue significativamente mayor que en los tejidos normales de la piel (t=2,192, P<0,05). La tasa de positividad de Notch1 en las lesiones cutáneas de pacientes con psoriasis vulgar fue del 76,47 %, que fue significativamente mayor que la de los tejidos normales de la piel (13,79 %) (t=29,215, P<0,01). La tasa positiva de FOXP1 en el grupo de psoriasis vulgar fue del 92,16 %, que también fue significativamente mayor que la del grupo de piel normal (65,52 %) (t=9,087, P<0,01). Además, la sobreexpresión de miR-34a promovió significativamente la expresión de Notch1 y Foxp1. Sin embargo, la inhibición de miR-34a redujo de manera importante los niveles de Notch1 y Foxp1. miR-34a se expresa en gran medida en los tejidos de la piel en pacientes con psoriasis vulgar y puede participar en el desarrollo de la psoriasis vulgar mediante la regulación de Notch1 y Foxp1.

ABSTRACT

Objetivo: Os agentes biológicos representam um grande avanço no tratamento da psoríase em placas moderada a grave. No entanto, variações de eficácia, segurança e custos dos tratamentos podem dificultar a escolha do agente terapêutico. Este estudo teve como objetivo atualizar o custo por resposta dos agentes biológicos disponíveis para psoríase no ROL de Procedimentos e Eventos em Saúde (ROL) da Agência Nacional de Saúde Suplementar (ANS). Métodos: Uma análise de custo por resposta foi utilizada para avaliar a razão de custo pelo desfecho Índice de Gravidade e Área da Psoríase (PASI) 90. Os resultados foram apresentados para o primeiro ano (ano I), que compreende a fase de indução e a fase manutenção até completar 52 semanas e foi realizada uma análise da efetividade do tratamento num cenário de orçamento fixo. Os custos dos tratamentos foram calculados com base nos preços de fábrica (PF18%) da Tabela da Câmara de Regulação do Mercado de Medicamentos de junho de 2021. Resultados: Para o ano I, o guselcumabe apresentou melhor resultado para custo por resposta (R$ 130.467) PASI 90, seguido por ixequizumabe, ustequinumabe, secuquinumabe, adalimumabe, infliximabe e etanercepte. No cenário com orçamento fixo, o guselcumabe demonstrou ser o agente capaz de tratar com sucesso (PASI 90) o maior número de pacientes. Atualização do custo-efetividade por resposta para psoríase em placas moderada a grave. Conclusão: Sob a perspectiva do Sistema de Saúde Suplementar do Brasil, o guselcumabe apresentou o melhor custo por resposta PASI 90, sendo, assim, a terapia com melhor custo-efetividade no tratamento da psoríase em placas moderada a grave disponível no ROL.


Objective: Biological agents represent a major advance in the treatment of moderate-to-severe plaque psoriasis. However, variations of efficiency, safety and costs of treatments make it difficult to select the drug. This study aims to update the cost per response of biological agents available in the Health Procedures and Events Roll (ROL) of the National Supplementary Health Agency (ANS). Methods: A cost-per-response analysis was used to assess the cost per outcome of Psoriasis Area and Severity Index (PASI) 90. Results were presented for the first year (I), which comprises induction and maintenance for 52 weeks and a fixed budget scenario analysis. Treatment costs were calculated based on the prices of the 2021 Medicines Market Regulation Chamber Table. Results: Analysis of year I, guselkumab showed the best result for cost per cost (R$ 130,467) PASI 90, followed by ixekizumab, ustekinumab, secukinumab, adalimumab, infliximab, and etanercept. In the fixedbudget analysis, guselkumab is the therapy capable of successfully treating (PASI 90) the largest number of patients. Conclusion: From the perspective of the Supplementary Health System in Brazil, guselkumab showed the best cost per response PASI 90, thus being the most cost-effective therapy in the treatment of moderate to severe plaque psoriasis available in the Brazilian ROL.
