RESUMEN

Phototherapy is broadly utilized for treatment of inflammatory skin conditions affecting pediatric patients. However, there are no specific guidelines or recommendations for implementing phototherapy in pediatric populations leading to variability in treatment procedures. Here, we present findings from a cross-sectional, survey-based study investigating the implementation of phototherapy in pediatric patients across the United States. A total of 39 sites from 19 different states identified via the National Psoriasis Foundation (NPF) Health Care Provider Directory responded. Common practices included a signed informed consent prior to performing phototherapy (86.4%, n = 32), no minimum age requirement for pediatric patients (91.8%, n = 34), the use of Fitzpatrick skin type to determine dosing protocol (100%, n = 37), and allowing parents to accompany their children into the lightbox (65%, n = 20). Our results provide insights into current common practices and themes for further study.

RESUMEN

A 43-year-old Japanese man who had suffered psoriasis vulgaris for eight years visited our hospital. His comorbidities were dyslipidemia, hyperuricemia, and obesity. He received phototherapy for six months, which did not result in improvement. Following treatment with brodalumab, his skin symptoms improved. However, seven months after brodalumab treatment, he received two doses of the mRNA-1273 COVID-19 vaccine, with a one-month interval between doses. One month following the second vaccination, his skin symptoms were exacerbated. He received additional NB-UVB therapy, but his skin symptoms did not improve. Nine months after the addition of NB-UVB therapy, treatment was switched to bimekizumab, and his skin became almost clear. Psoriasis is often associated with comorbidities like metabolic syndrome. Currently, additional COVID-19 vaccination is recommended for high-risk cases such as those with metabolic syndrome. Therefore, it is essential to remain vigilant regarding the potential exacerbation of psoriasis following COVID-19 vaccination even during treatment with highly effective biologic therapy.

RESUMEN

BACKGROUND: Psoriasis is a chronic, immune-mediated, polygenic skin disease that is common in clinical practice and often develops on the extremities, back, and scalp of patients. In that psoriasis lesions are stubborn and prone to recurrence, it has a serious impact on patients' quality of life and is detrimental to their physical and psychological health. Auricular acupuncture is one of the traditional Chinese medical treatments, which has the advantages of low adverse effects and simple operation and has been widely used in clinical practice with good efficacy. However, there has been no systematic evaluation of auricular acupuncture in the treatment of psoriasis. This protocol aims to evaluate the effectiveness and safety of auricular acupuncture in patients with psoriasis. METHODS: We will search the following 8 databases including PubMed, MEDLINE, EMBASE, Cochrane Library, CNKI, Wan Fang, VIP, and CBM databases for randomized controlled trials of auricular acupuncture treated psoriasis from their inception to 10 October 2022. We will analyze the data meeting the inclusion criteria with the RevMan V.5.4 software. Two authors will assess the quality of the study with the Cochrane systematic evaluation tool. Treatment effectiveness and the psoriasis area and severity index are defined as the main outcomes, and the additional outcomes include itchy, dermatology life quality index, relapse rate, and adverse events. RESULTS: This study will review and evaluate the available evidence on the effectiveness and safety of auricular acupuncture for psoriasis. CONCLUSIONS: The results of this study will provide evidence for the effectiveness and safety of treating psoriasis, providing clinicians and patients with appropriate treatment options for this disease.

RESUMEN

Psoriasis is a systemic, chronic, immune-mediated disease that affects approximately 2-3% of the world's population. The etiology and pathophysiology of psoriasis are still unknown, but the activation of the adaptive immune system with the main role of T-cells is key in psoriasis pathogenesis. The modulation of the local neuroendocrine system with the downregulation of pro-inflammatory and the upregulation of anti-inflammatory messengers represent a promising adjuvant treatment in psoriasis therapies. Vitamin D receptors and vitamin D-mediated signaling pathways function in the skin and are essential in maintaining the skin homeostasis. The active forms of vitamin D act as powerful immunomodulators of clinical response in psoriatic patients and represent the effective and safe adjuvant treatments for psoriasis, even when high doses of vitamin D are administered. The phototherapy of psoriasis, especially UVB-based, changes the serum level of 25(OH)D, but the correlation of 25(OH)D changes and psoriasis improvement need more clinical trials, since contradictory data have been published. Vitamin D derivatives can improve the efficacy of psoriasis phototherapy without inducing adverse side effects. The anti-psoriatic treatment could include non-calcemic CYP11A1-derived vitamin D hydroxyderivatives that would act on the VDR or as inverse agonists on RORs or activate alternative nuclear receptors including AhR and LXRs. In conclusion, vitamin D signaling can play an important role in the natural history of psoriasis. Selective targeting of proper nuclear receptors could represent potential treatment options in psoriasis.

RESUMEN

Objective: Through the analysis of the morphological distribution of psoriasis lesions, we can study the relationship between psoriasis lesions and age, gender, and course of disease and dialectically look at the location of lesion morphology and the impact of course of disease on it, so as to provide more basis for the treatment of psoriasis. Method: Through a questionnaire survey of 512 patients in the dermatology clinic of a well-known traditional Chinese medicine hospital in Jiangsu Province, their symptoms met the diagnostic criteria of psoriasis in Chinese clinical dermatology. The current situation of psoriasis was analyzed by literature analysis, and the collected data were analyzed by general mean analysis, analysis of variance, and descriptive analysis. Result: There were some differences in the proportion of male to female in 512 patients. It is possible to conclude that male incidence rate is higher than that of women. It can be deduced from bad habits such as heavy drinking and smoking in male life. Bad habits can reduce male immunity and cause disease. The distribution of skin lesions in different parts shows that the skin is more affected by the outside world, which leads to the repeated attack of psoriasis. The incidence of chest, scalp, and upper arm is also relatively high. There have been similar demonstrations in relevant medical data, which may be related to the vascular density in them. Some substances that induce psoriasis in the dense blood vessels are easy to accumulate here, leading to the pathogenic bacteria to induce the onset of psoriasis. Conclusion: By studying the distribution of psoriasis lesions and the correlation between lesions, gender, and disease course, we can improve the dialectical treatment of psoriasis, which has reference significance, and provide a new thinking direction for the treatment system theory of psoriasis.

RESUMEN

OBJECTIVE: To systematically review the occurrence of adverse events/adverse reactions (AEs/ARs) induced by acupoint catgut embedding therapy for psoriasis vulgaris (PV) and its safety. METHODS: Randomized controlled trials, controlled clinical trials, cohort studies, case-control studies, case-series, and case reports concerning the treatment of PV with acupoint catgut embedding therapy were searched from Chinese and English databases from their inception to January 7th, 2021. The AEs/ARs related to acupoint catgut embedding therapy for PV were subjected to descriptive statistics, followed by the analysis of possible reasons. RESULTS: Finally, 16 studies were included, involving 1 158 patients. A total of 79 cases were reported to present with mild to moderate AEs/ARs related to acupoint catgut embedding therapy for PV, and there were no serious AEs/ARs or death cases. The most common AEs/ARs were local redness, swelling, heat, and pain (31.65%,25/79), followed by low-grade fever and fatigue (29.11%,23/79), isomorphic reaction (16.46%,13/79), local induration (13.92%,11/79), and fainting (8.86%,7/79). In terms of embedding materials, catgut (93.67%,74/79) and lumbar puncture needles or other puncture needles (49.37%,39/79) were proved the most common AEs/ARs-inducing factors. The proportion of AEs/ARs resulting from treatment interval≤two weeks (67.09%,53/79) and treatment course≤eight weeks (55.70%,44/79) was relatively high. Because the incidence of AEs/ARs fails to be calcula-ted, it is not yet possible to accurately assess the risk and safety of acupoint catgut embedding therapy for PV. CONCLUSION: Available evidence suggests that in the treatment of PV, acupoint catgut embedding therapy may induce a series of mild to moderate AEs/ARs, so its clinical practice deserves attention. We should strictly grasp its indications and contraindications, and prevent the occurrence of related AEs/ARs by standardizing the operation and improving the embedding materials.

RESUMEN

Psoriasis is a chronic autoimmune skin disorder triggered by either genetic factors, environmental factors, life style, or a combination thereof. Clinical investigations have identified pathogenesis, such as T cell and cytokine-mediated, genetic disposition, antimicrobial peptides, lipocalin-2, galectin-3, vaspin, fractalkine, and human neutrophil peptides in the progression of psoriasis. In addition to traditional therapies, newer therapeutics, including phosphodiesterase type 4 (PDE4) inhibitors, Janus kinase (JAK) inhibitors, monoclonal antibodies (mAbs), gene therapy, anti-T cell therapy, and phytoconstituents have been explored. In this review, we highlight nanotechnology-related developments for psoriasis treatment, including patented delivery systems and therapeutics currently in clinical trials.

RESUMEN

RATIONALE: Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is a rare disease without standard treatments. Tripterygium wilfordii hook f (TwHF) is a traditional Chinese herb with anti-inflammatory effect, and 1.0 mg/(kg·d) dose of Tripterygium glycosides has been reported to significantly improve the disease activity of a SAPHO patient in a case report. However, the optimal dose of TwHF is still unclear. Here, we report the first case of SAPHO patient who achieved rapid remission in clinical symptoms after receiving 1.5 mg/(kg·d) dose of Tripterygium glycosides treatment. PATIENT CONCERNS: A 67-year-old woman noted palmoplantar pustulosis and pain in the anterior chest wall and waist. Bone scintigraphy demonstrated the typical tracer accumulation feature and magnetic resonance images showed bone marrow edema in lumbosacral vertebra. DIAGNOSES: The diagnosis was made by dermatological and osteoarticular manifestations and classical signs in bone scintigraphy in accordance with the diagnostic criteria proposed in 2012. INTERVENTIONS: Tripterygium glycosides was given with a primary dose of 1.5 mg/(kg·d) for 1 month and then reduced at a rate of 10 mg every 2 weeks until 1.0 mg/(kg·d) for a long-term maintenance. OUTCOMES: Fast-induced remission on clinical manifestations was achieved and magnetic resonance imaging abnormality was improved significantly. Additionally, no apparent side effects were observed. LESSONS: 1.5 mg/(kg·d) dose of Tripterygium glycosides seems to have fast-induced remission than 1.0 mg/(kg·d) with reliable safety. Besides, Tripterygium glycosides may also have a pharmacological effect of inhibiting osteolysis and enhancing bone strength.

RESUMEN

BACKGROUND: Several studies have investigated the association between selenium levels and skin diseases, but reached inconsistent results. OBJECTIVE: This systematic review and meta-analysis was conducted to evaluate the association between selenium levels and skin diseases. METHODS: A systematic search was conducted in public databases to identify all relevant studies, and study-specific standard mean differences (SMD) and 95% confidence intervals (CI) were pooled to compare the selenium levels between different groups. RESULTS: Twenty-seven studies were identified with a total of 1315 patient and 7181 healthy controls. Compared with controls, no significant difference in selenium was found in patients with vitiligo (SMD = 0.53, 95% CI: -0.40 to 1.45), alopecia areata (SMD = 0.47, 95% CI: -2.72 and 3.65), or eczema (SMD = 0.12, 95% CI: -0.24 to 0.48). A lower selenium level was found in patients with psoriasis (SMD = -0.62, 95% CI: -1.15 to -0.10), acne vulgaris (SMD = -1.02, 95% CI: -1.45 to -0.60), chloric acne (SMD = -2.35, 95% CI: -3.15 to -1.55), and atopic dermatitis (SMD = -2.62, 95% CI: -3.00 to -2.24). As for disease severity, severe patients had a higher selenium level than mild patients in psoriasis (SMD = 0.72, 95% CI: 0.07-1.38), but no difference was found in vitiligo (SMD = -0.26, 95% CI: -2.38 to 1.85) and alopecia areata (SMD = 0.46, 95% CI: -0.34 to 1.26). CONCLUSION: Selenium levels were associated with several skin diseases and the disease severity, and high selenium levels tended to be a protective factor in certain skin diseases.

RESUMEN

Palmoplantar pustulosis (PPP) is a chronic, recurrent skin disease belonging to the spectrum of psoriasis. It is characterized by an eruption of sterile pustules on the palms and soles. Recent studies in PPP have focused on genetic differences between pustular phenotypes and the role of the innate immunological system and the microbiome in the etiopathogenesis of the disease. Mutations in IL36RN (a major predisposing factor for generalized pustular psoriasis) were found in selected patients with PPP and were associated with earlier disease onset. Studies have shown that the interleukin (IL)-17 and IL-36 pathways might be involved in the pathogenesis of PPP. A microbiome has been demonstrated in the vesicopustules of PPP, and an abundance of Staphylococcus appears to be increased by smoking. Improved understanding of the underlying etiopathogenesis of PPP has led to advances in treatment options, and targeted therapies for PPP have been evaluated or are under evaluation against more than 12 molecules in ongoing clinical trials. These targets include CXCR2 (IL-8 receptor type B), granulocyte colony-stimulating factor receptor, IL-1 receptor, IL-8, IL-12, IL-23, IL-17A, IL-17 receptor, IL-36 receptor, phosphodiesterase-4, and tumor necrosis factor-α.

RESUMEN

Psoriasis is a chronic inflammatory skin disease that involves numerous types of immune cells and cytokines resulting in an inflammatory feedback loop and hyperproliferation of the epidermis. A more detailed understanding of the underlying pathophysiology has revolutionized anti-psoriatic treatment and led to the development of various new drugs targeting key inflammatory cytokines such as IL-17A and IL-23. Successfully treated psoriatic lesions often resolve completely, leaving nothing visible to the naked eye. However, such lesions tend to recur within months at the exact same body sites. What is left behind at the cellular and molecular levels that potentially reinitiates psoriasis? Here, we elucidate the cellular and molecular "scar" and its imprints left after clinical resolution of psoriasis treated with anti-TNFα, anti-IL-17, or anti-IL-23 antibodies or phototherapy. Hidden cytokine stores and remaining tissue-resident memory T cells (TRMs) might hold the clue for disease recurrence.

RESUMEN

Nanodermatology is an emerging, multidisciplinary science, arising from the convergence of nanotechnology, pharmacology, physics/biophysics, chemistry/biochemistry, chemical engineering, material science, and clinical medicine. Nanodermatology deals with (a) skin biology, anatomy, and physiology at the nanoscale ("skin nanobiology"), (b) diagnosis performed by means of novel diagnostic devices, assisted by nanobiotechnologies ("nanodiagnosis"), and (c) treatment through innovative therapeutic agents, including phototherapy ("photonanotherapy"/"photonanodermatology") and systemic/topical drug administration ("nanotherapy") at the nanoscale, and drug delivery-such as transdermal or dermal drug delivery (TDDD/DDD)-enhanced and improved by nanostructures and nanodrugs ("nanodrug delivery"). Nanodermatology, as a super-specialized branch of dermatology, is a quite recent specialty: the "Nanodermatology Society" founded by the eminent dermatologist Dr. Adnan Nasir, was established in 2010, with the aim of bringing together different stakeholders, including dermatologists, nanotechnology scientists, policy-makers and regulators, as well as students and medical residents. Psoriasis has a prevalence of 2-3% worldwide and imposes a severe clinical and societal burden. Nanodermatology-based solutions appear promising for the proper treatment and management of psoriasis, assisting and enhancing different steps of the process of health-care delivery: from the diagnosis to the therapeutics, paving the way for a personalized approach, based on the specific dysregulated biomarkers.

RESUMEN

BACKGROUND: Retinoic acid receptor-related orphan receptor gamma t (RORγt) has critical roles in the development, maintenance and function of interleukin (IL)-17-producing cells and is a highly attractive target for the treatment of IL-17-mediated autoimmune disease, particularly psoriasis. On the other hand, RORγt is also critical for controlling apoptosis during thymopoiesis, and genetic RORγt ablation or systematic RORγt inhibition cause progressive thymic aberrations leading to T cell lymphomas. OBJECTIVE: We investigated whether topical administration of our novel RORγt inhibitor, S18-000003 has therapeutic potential for psoriasis with low risk of thymic aberrations. METHODS: We evaluated the effect of topical S18-000003 on psoriasis-like skin inflammation and influence on the thymus in a 12-O-tetradecanoylphorbol-13-acetate-induced K14.Stat3C mouse psoriasis model. RESULTS: S18-000003 markedly inhibited the development of psoriatic skin inflammation via suppression of the IL-17 pathway. In the skin, S18-000003 suppressed all subsets of IL-17-producing cells that we previously identified in this psoriasis model: Th17 cells, Tc17 cells, dermal γδ T cells, TCR- cells that probably included innate lymphoid cells, and CD4-CD8- double-negative αß T cells. Notably, neither reduction of CD4+CD8+ double-positive thymocytes nor dysregulation of cell cycling was observed in S18-000003-treated mice, even at a high dose. CONCLUSION: Our topically administered RORγt inhibitor is a potential therapeutic agent for psoriasis with low risk of thymic lymphoma.

RESUMEN

In obesity, hypertrophic adipocytes secrete high amounts of adipocytokines, resulting in low-grade inflammation amplified by infiltrating proinflammatory macrophages, oxidative stress, hypoxia, and lipolysis. These chronic proinflammatory conditions support the development of type II diabetes and cardiovascular diseases, but the mechanisms of obesity-related exacerbation of inflammatory skin disorders like psoriasis are unclear. In this study, we uncovered dietary saturated fatty acids (SFAs) as major risk factors for the amplification of skin inflammation, independent of obesity-related parameters such as fat mass extension, adipocytokine levels, and glucose homeostasis. Correlation analyses in a cohort of psoriasis vulgaris patients showed that free fatty acid serum level was the only obesity-associated parameter affecting disease severity. Studies in mice with high-fat diet-induced obesity with psoriasiform inflammation confirmed this critical role of free fatty acids. An increase of free fatty acids in healthy, lean mice alone was sufficient to induce an exacerbation of psoriasiform inflammation. In particular, saturated fatty acids sensitize myeloid cells to an increased inflammatory response in answer to proinflammatory stimuli, which in turn augments the activation of keratinocytes. Consequently, reduction of nutritional saturated fatty acids alone diminished the psoriatic phenotype in obese mice. Thus, our findings may open new perspectives for adjuvant dietary measures accompanying anti-inflammatory psoriasis therapies in lean and obese patients.

RESUMEN

Generalized pustular psoriasis (GPP) is a subtype of pustular psoriasis characterized by painful and occasionally disfiguring cutaneous manifestations with sepsis-like systemic symptoms. Affecting any age and race, GPP can occur with other forms of psoriasis or by itself. Stimuli for flares include medications, infections and environmental triggers. The interleukin family and caspase recruitment domain family have been implicated in its pathogenesis. Other forms of pustular psoriasis include impetigo herpetiformis, palmoplantar pustular psoriasis, annular pustular psoriasis and acrodermatitis continua of Hallopeau. Treatment is not well established, but includes the use of retinoids, methotrexate, cyclosporine, corticosteroids, TNF-alpha inhibitors, topical therapy and phototherapy. The use of TNF-alpha inhibitors may result in the formation of antidrug antibodies and should be administered with methotrexate.

RESUMEN

Despite the wide consumption of coffee, its anti-inflammatory effect on clinical severity of psoriasis is still debatable. The aim of this study was to evaluate the association between the coffee consumption and clinical severity of psoriasis in a sample of patients stratified according to the presence of the metabolic syndrome (MetS) and smoking. This cross-sectional case-control observational study was conducted on 221 treatment-naïve psoriatic patients. Lifestyle habits, anthropometric measures, clinical and biochemical evaluations were obtained. Clinical severity of psoriasis was assessed by Psoriasis Area and Severity Index (PASI) score. Data on energy caloric intake and coffee consumption were collected using a 7-day food diary record. The coffee consumption was analyzed as coffee intake (consumers and non-consumers) and daily servings (range 0-4 servings/day). Coffee consumers have a lower PASI score vs non-consumers (p < 0.001). The lowest PASI score and MetS prevalence were found in patients consuming 3 cups of coffee/day (p < 0.001), which was also the most common daily serving (34.8%), whereas the highest PASI score was found among those drinking ≥ 4 cups/day. Grouping the case patients according to smoking and MetS, the best odds of PASI score was observed in those drinking 3 cups of coffee per day and no smokers, after adjusting for total energy intake (OR 74.8; p < 0.001). As a novel finding, we reported a negative association between coffee intake, MetS prevalence and clinical severity of psoriasis. The evaluation of the anti-inflammatory effect of coffee on clinical severity of psoriasis, whose metabolic risk increases along with its clinical severity, could be of great importance from a public health perspective.
