Project description:Psoriasis is a chronic inflammatory skin disease associated with various factors. Recently, alterations in the gut and skin microbiomes have been shown to interact with host immunity, affect skin barrier function, as well as development and progression of psoriasis. We aimed to analyze the microbiota of the scalp of patients with psoriasis and determine the characteristics of the microbiome according to disease severity. We investigated the scalp microbiome of 39 patients with psoriasis scalp lesions and a total of 47 samples were analyzed. The patients were divided into mild, moderate, and severe groups according to the European recommendations for scalp psoriasis. For bacterial identification, we utilized the SILVA database targeting the V3 region of the 16 S rRNA gene. The mean Shannon index escalated along with disease severity, and the diversity of the scalp microbiome tended to increase with disease severity (R = 0.37, p < 0.01). The relative abundance of Pseudomonas was increased in severe scalp psoriasis (0.49 ± 0.22) compared to the mild group (0.07 ± 0.03, p = 0.029), and Diaphorobacter was enriched in the mild group (0.76 ± 0.16%) compared to the severe group (0.44 ± 0.22, p < 0.001). We identified that increased diversity of the scalp microbiome and the relative abundance of Pseudomonas are associated with the severity of scalp psoriasis.

Project description:The efficacy and safety of betamethsone dipropionate 0.05% with salicylic acid 2% scalp lotion was evaluated in 60 patients with moderate to severe scalp psoriasis. Out of 120 patients with scalp psoriasis 60 patients received PUVASOL alone and 60 patients received PUVASOL alongwith lotion 0.05% betamethasone dipropionate with 2% salicylic acid scalp application for 3 weeks. The erythema, induration, scales and pruritus steadily improved in patients throughout the 3 weeks treatment course with betamethasone dipropionate with salicylic acid scalp application. At the end of therapy 84.3% of those patients receiving PUVASOL and betamethasone dipropionate-salicylic acid combination had 75% improvement of their scalp psoriasis versus 34.9% of those patients using PUVASOL alone. Complete clearing of the scalp was seen in 35% patients receiving therapy with topical betamethasone-salicylic acid and 11.6% with PUVASOL alone. Local side effects were primarily burning and stinging in 5 (83%) cases treated with topical betamethasone salicylic acid scalp application and 1 (1.6%) receiving PUVASOL alone. Combined therapy with PUVASOL and topical betamethasone dispropionate 0.05% with salicyclic acid 2% application appears to be safe and an effective treatment for scalp psoriasis.

Project description:Scalp psoriasis shows a variable clinical spectrum and in many cases poses a great therapeutic challenge. However, it remains unknown whether the immune response of scalp psoriasis differs from understood pathomechanisms of psoriasis in other skin areas. We sought to determine the cellular and molecular phenotype of scalp psoriasis by performing a comparative analysis of scalp and skin using lesional and nonlesional samples from 20 Caucasian subjects with untreated moderate to severe psoriasis and significant scalp involvement and 10 control subjects without psoriasis. Our results suggest that even in the scalp, psoriasis is a disease of the inter-follicular skin. The immune mechanisms that mediate scalp psoriasis were found to be similar to those involved in skin psoriasis. However, the magnitude of dysregulation, number of differentially expressed genes, and enrichment of the psoriatic genomic fingerprint were more prominent in skin lesions. Furthermore, the scalp transcriptome showed increased modulation of several gene-sets, particularly those induced by interferon-gamma, compared with that of skin psoriasis, which was mainly associated with activation of TNFα/L-17/IL-22-induced keratinocyte response genes. We also detected differences in expression of gene-sets involving negative regulation, epigenetic regulation, epidermal differentiation, and dendritic cell or Th1/Th17/Th22-related T-cell processes.

We also detected differences in expression of gene-sets involving negative regulation, epigenetic regulation, epidermal differentiation, and dendritic cell or Th1/Th17/Th22-related T-cell processes. To define the transcriptomic profile of scalp skin, punch biopsies (6 mm diameter) were obtained from 20 Caucasian patients with untreated moderate to severe psoriasis with significative scalp involvement and 10 control subjects without psoriasis (N). Lesional (LS) samples were isolated from the infiltrated border of a plaque of psoriasis. Non lesional (NL) samples were taken from scalp areas with no visible psoriasis between the infiltrated plaques.

Project description:During the 28th Congress of the European Academy of Dermatology and Venereology (EADV) held in Madrid in October 2019, an industry hub was dedicated to the long-term management of psoriasis. Psoriasis is a systemic inflammatory disease primarily involving the skin that affects up to 4% of the European population, the majority of whom present with chronic plaque psoriasis. Topical therapies are well established in the first-line treatment of psoriatic plaque flares. Nevertheless, as psoriasis is a chronic disease, long-term control should be considered. The aim of the session was to provide expert opinion on the benefit of long-term maintenance therapy in chronic plaque psoriasis and introduce the concept of pro-active management to decrease the number of relapses and improve patient quality of life. The current guidelines and recommendations were reviewed, as well as the available data on published clinical trials. There is still an important role for topical therapy in psoriasis and current recommendations suggest a maintenance regimen for psoriasis. Adherence optimization and proactive management of relapse can be key factors for obtaining clinical outcomes in topical long-term therapy. Calcipotriol/betamethasone dipropionate foam is the only topical formulation with long-term data as a twice-weekly proactive treatment approach for up to 52 weeks for chronic plaque psoriasis.

Project description:BackgroundWhile treatment options exist for solitary or disseminated Kaposi sarcoma (KS) disease, there are currently no standardized clinical treatment guidelines for cutaneous KS.ObjectiveThis systematic review seeks to identify safe and effective topical treatments for cutaneous KS lesions.MethodsWe conducted a systematic review using peer-reviewed articles from January 1970 to September 2021 published in the PubMed/MEDLINE and EMBASE databases.ResultsFrom the initial search that yielded 590 studies, 34 met the inclusion criteria and were selected. Of the 34 studies, seven were clinical trials, 26 were case reports/series and one was a multicentre study. A total of 634 patients were included in our review. The three most common topical treatments used for cutaneous KS were imiquimod, alitretinoin and timolol. Topical alitretinoin was used in three case reports and three clinical trials. Topical imiquimod was used in eight case reports, one prospective phase II cohort study and one comparative single-blinded non-controlled clinical study. Topical timolol was used in nine case reports/series. Our review also identified reports of less widely used topical treatments for cutaneous KS. These include topical diphencyprone (DPCP), all-trans-retinoic-acid, rapamycin and bleomycin-dimethylsulfoxide (BLM-DMSO) which achieved variable response rates but have not been widely studied.ConclusionTopical alitretinoin, imiquimod and timolol demonstrated positive responses for cutaneous KS and the treatments were well tolerated. These three topical treatment modalities could be considered by clinicians when treating cutaneous KS.

Project description:Psoriasis of the scalp, face, intertriginous areas, genitals, hands, feet, and nails is often underdiagnosed, and disease management can be challenging. Despite the small surface area commonly affected by psoriasis in these locations, patients have disproportionate levels of physical impairment and emotional distress. Limitations in current disease severity indices do not fully capture the impact of disease on a patient's quality of life, and, combined with limitations in current therapies, many patients do not receive proper or adequate care. In this review, we discuss the clinical manifestations of psoriasis in these less commonly diagnosed areas and its impact on patient quality of life. We also examine clinical studies evaluating the effectiveness of therapies on psoriasis in these regions. This article highlights the need to individualize treatment strategies for psoriasis based on the area of the body that is affected and the emerging role of biologic therapy in this regard.

Project description:In Part One of this two-part series, we discussed skin physiology and anatomy as well as generalities concerning topical analgesics. This modality of therapy has lesser side effects and drug-drug interactions, and patients tolerate this form of therapy better than many oral options. Unfortunately, this modality is not used as often as it could be in chronic pain states, such as that from neuropathic pain. Part Two discusses specific therapies, local anesthetics, and other drugs, as well as how a clinician might use specific aspects of a patient's neuropathic pain presentation to help guide them in the selection of a topical agent.
