Abstract
To assess (i) the prevalence of oral colonization by Candida spp. in patients with psoriasis and (ii) the prevalence of oral lesions associated with Candida spp. in patients with psoriasis and identify the risk factors for oral lesions. A systematic review was conducted in accordance with PRISMA criteria. The PROSPERO registration code is CRD42019127178. PubMed, Scopus and Web of Science were used as search engines. Meta-analyses and trial sequential analyses were performed. Among the 5805 retrieved records, nine articles were included. Among 530 psoriatic patients, 255 patients had an oral Candida spp. colonisation with an odds ratio (OR) = 3.44 (95% CI:2.38-5.00). Among 490 psoriatic patients, 43 patients developed oral Candida spp. lesions with an OR = 5.31 (95% CI:1.04-27.23). Among the patients without the main predisposing factors for infections, psoriatic patients had a higher OR (3.48, 95% CI: 2.0-6.0) for Candida spp. colonization, but not for Candida spp. infection, when compared with healthy controls (p-value > 0.05). Meta-analysis showed a higher risk of Candida spp. colonisation in patients with psoriasis. Patients who received immunosuppressive therapies were also at higher risk of developing oral lesions. Further studies are needed to understand these associations.

Abstract
AIMS To identify the main types of oral lesions associated with psoriasis. METHODS AND RESULTS It was a systematic review, based on a search performed in the PubMed/Medline, and Scielo databases, and an associated manual search. Descriptors were selected from DeCs/MeSH and the PICOS strategy (population, intervention, comparison, outcomes, and study design) was applied. Randomized clinical trials and retrospective and prospective studies published from 2000 to 2022 were included, according to the PRISMA parameters (Preferred Reporting Items for Systematic Reviews and Meta-Analysis), registered in the PROSPERO platform. The STROBE quality scale (Strengthening the Reporting of Observational studies in Epidemiology) was also used. One hundred fourteen articles were identified using the search strategy, and nine articles were found in the manual search. Of the sixty-six preselected articles, seven were included in the study. Although it was not possible to identify a specific oral lesion associated with psoriasis, there was a greater occurrence of geographic tongue, fissured tongue, and Candida sp. infection CONCLUSION: Evidence shows that although patients with psoriasis may exhibit lesions in the oral mucosa, they are not specific to this condition. Further epidemiological studies are needed to address the association of psoriasis with possible changes in the oral mucosa.

Abstract
BACKGROUND Studies focusing on the relationship between periodontitis and systemic diseases have suggested a possible association between these two chronic and inflammatory disorders. We aimed to comparatively investigate the salivary oxidative status, biomarker levels, clinical findings, and the microbial load on subgingival biofilm samples in psoriasis patients and controls. METHODS Forty participants were allocated into four groups as follows: (1) systemically and periodontally healthy (C group); (2) systemically healthy with periodontitis (P group); (3) psoriasis (Ps) and periodontally healthy (Ps-C group); and (4) Ps with periodontitis (Ps-P group). Subgingival biofilm samples were obtained to detect the periodontopathogenic agents by Real-time PCR (qPCR). The total antioxidant status (TAS) (mmol/l), total oxidant status (TOS) (μmol/l), and arylesterase (ARE) activity (U/L) were analyzed using saliva samples. RESULTS The level of TOS and oxidative stress index (OSI) were significantly higher in patients with Ps-P and P compared to controls (P = 0.001, and P ˂ 0.001, respectively). ARE levels were higher in controls compared to Ps and P (P ˂ 0.001). The prevalences of bacteria detected in subgingival biofilm samples were similar between all groups (P > 0.05). CONCLUSIONS This study reported that psoriasis may amplify TOS and OSI, and the co-existence of psoriasis and periodontitis may aggravate oxidative stress.

Abstract
Psoriasis is one of the most frequent skin diseases. The cause of psoriasis is not fully expained as there are many factors (infectious, traumatic, hormonal, and chemical) that may play a role in the manifestation of its symptoms. One of the factors that may contribute to the appearance of psoriatic lesions may be the lesions in the oral cavity. The occurrence of lesions in the oral cavity is defined as rare, what can be explained by their nonspecific clinical image, and also by the possibility of being overlooked. Most characteristic symptoms of psoriasis occurring in the oral cavity are the geographic tongue and fissured tongue. It is also believed that there is a correlation between psoriasis and oral health- the periodontal and teeth condition as well as changes in saliva secretion. The psoriasis arthritis changes can also affect temporomandibular joint and impair the function of stomatognathic system. Because of these reports, cooperation of dermatologists and dentists in psoriasis care seems to be necessary.

Abstract
Plaque psoriasis is an immune-mediated inflammatory skin disease associated with the dysregulation of cytokines, especially those involved in the interleukin (IL)-23/IL-17 pathways. In recent years, there has been growing interest in developing biologic therapies that target these pathways. However, inhibition of the cytokines of the IL-23/IL-17 pathways may increase patients' risk of developing fungal infections, particularly oral candidiasis. Therefore, it is important that dermatology practitioners can effectively diagnose and treat oral candidiasis. In this review, we examine the role of the IL-23/IL-17 pathways in antifungal host defense, and provide a practical guide to the diagnosis and treatment of oral candidiasis in patients with psoriasis. Overall, while treatment with anti-IL-17 medications leads to an increased incidence of oral candidiasis in patients with psoriasis, these cases are typically mild or moderate in severity and can be managed with standard antifungal therapy without discontinuing treatment for psoriasis. If applicable, patients with psoriasis should also be advised to practice good oral hygiene and manage or control co-existing diabetes, and should be provided with information on smoking cessation to prevent oral candidiasis.

Abstract
Psoriasis is one of the most common chronic inflammatory skin diseases, constituting a significant health and socioeconomic problem. Despite numerous therapeutic options, the results of treatment very often remain insufficient. It is extremely important to remember that many external factors impact the effectiveness of therapy. This article discusses the importance of emollients in therapy and the influence of infectious agents and injuries on the course of psoriasis. Understanding the above-mentioned factors in the treatment of psoriasis is critical to achieve satisfactory therapeutic effects.

Abstract
BACKGROUND Psoriasis patients are more frequently colonised with Candida species. The correlation between fungal colonisation and clinical severity is unclear, but may exacerbate psoriasis and the impact of antipsoriatic therapies on the prevalence of Candida is unknown. OBJECTIVES To examine the prevalence of C species in psoriasis patients compared to an age- and sex-matched control population, we investigated the influence of Candida colonisation on disease severity, immune cell activation and the interplay on psoriatic treatments. METHODS The prevalence of C species was examined in 265 psoriasis patients and 200 control subjects by swabs and stool samples for fungal cultures. Peripheral mononuclear blood cells (PBMCs) were collected from 20 fungal colonised and 24 uncolonised patients and stimulated. The expression of interferon (IFN)-γ, IL-17A, IL-22 and tumour necrosis factor (TNF)-α from stimulated PBMCs was measured by quantitative real-time polymerase chain reaction (qPCR). RESULTS A significantly higher prevalence for Candida was detected in psoriatic patients (p ≤ .001) compared to the control subjects; most abundant in stool samples, showing Candida albicans. Older participants (≥51 years) were more frequent colonised, and no correlation with gender, disease severity or systemic treatments like IL-17 inhibitors was found. CONCLUSIONS Although Candida colonisation is significantly more common in patients with psoriasis, it does not influence the psoriatic disease or cytokine response. Our study showed that Candida colonisation is particularly more frequent in patients with psoriasis ≥51 years of age. Therefore, especially this group should be screened for symptoms of candidiasis during treatment with IL-17 inhibitors.

Abstract
Candida albicans (CA) infections have been associated with psoriasis onset or disease flares. However, the integrated immune response against this fungus is still poorly characterized in psoriasis. We studied specific immunoglobulins in plasma and the CA response in cocultures of circulating memory CD45RA- cutaneous lymphocyte antigen (CLA)+/- T cell with autologous epidermal cells from plaque and guttate psoriasis patients (cohort 1, n = 52), and also healthy individuals (n = 17). A complete proteomic profile was also evaluated in plaque psoriasis patients (cohort 2, n = 114) regarding their anti-CA IgA levels. Increased anti-CA IgA and IgG levels are present in the plasma from plaque but not guttate psoriasis compared to healthy controls. CA cellular response is confined to CLA+ T cells and is primarily Th17. The levels of anti-CA IgA are directly associated with CLA+ Th17 response in plaque psoriasis. Proteomic analysis revealed distinct profiles in psoriasis patients with high anti-CA IgA. C-C motif chemokine ligand 18, chitinase-3-like protein 1 and azurocidin were significantly elevated in the plasma from plaque psoriasis patients with high anti-CA levels and severe disease. Our results indicate a mechanism by which Candida albicans exposure can trigger a clinically relevant IL-17 response in psoriasis. Assessing anti-CA IgA levels may be useful in order to evaluate chronic psoriasis patients.

Abstract
Microbiota is a kind of ecosystem inhabiting some organs, supporting their proper functioning, but also having a significant impact on the development of the immune system. The largest reservoir of microbiota is the digestive tract, where the largest number of lymphocytes is also present. Literature gradually increases the number of studies assessing the relationship between intestinal dysbiosis and the development of various parenteral diseases. This article presents the latest data from the medical literature regarding intestinal microbiota and barrier in patients with psoriasis. In the cited studies, a quantitative advantage of Firmicutes phylum over Bacteroidetes phylum and a smaller colonization of Actinobacteria phylum has been demonstrated. In terms of the species, colonization of bacteria Faecalibacterium prausnitzii and Akkermansia muciniphilia was reduced, and Escherichia coli increased. Regarding the participation of individual taxonomic units, the results in the cited studies are partly different. However, all revealed significant differences between the intestinal
microbiota of patients with psoriasis and a healthy population, which suggests the importance of
intestinal dysbiosis in the development of this disease. It seems more important that what leads to
disturbances in the metabolic balance is not so much the quantity of individual taxonomic units
as their disproportions. In some studies, the deviations in microbiota correlated with the level
of metabolites and indicators of inflammation. Moreover, some studies revealed a significantly
higher incidence of Candida in the oral cavity as well as in the stool samples of patients with psoriasis.
There are also reports in the literature in which the occurrence of intestinal inflammation
and the impairment of the intestinal barrier in patients with psoriasis have been demonstrated.
These observations indicate interrelations between psoriasis and intestinal disorders as well as the
involvement of dysbiosis in both associations and the pathogenesis of psoriasis.

Abstract
Under steady-state conditions, the immune system is poised to sense and respond to the microbiota. As such, immunity to the microbiota, including T cell responses, is expected to precede any inflammatory trigger. How this pool of preformed microbiota-specific T cells contributes to tissue pathologies remains unclear. Here, using an experimental model of psoriasis, we show that recall responses to commensal skin fungi can significantly aggravate tissue inflammation. Enhanced pathology caused by fungi preexposure depends on Th17 responses and neutrophil extracellular traps and recapitulates features of the transcriptional landscape of human lesional psoriatic skin. Together, our results propose that recall responses directed to skin fungi can directly promote skin inflammation and that exploration of tissue inflammation should be assessed in the context of recall responses to the microbiota.

Abstract
The oral microbiota is complex, multikingdom, interactive, and involves extensive biofilm formation. While dominated by bacteria, Candida is a frequent member of this microbiota; however, several other potentially pathogenic fungi (among around 100 identified species) appear to reside in some individuals, including Cryptococcus, Aspergillus, and Fusarium. Oral candidiasis may manifest as a variety of disease entities in normal hosts and in the immunocompromised. These include pseudomembranous candidiasis (thrush), hyperplastic or atrophic (denture) candidiasis, linear gingival erythema, median rhomboid glossitis, and angular cheilitis. The purpose of this review is to describe the oral fungal microbiota (ie, oral mycobiota), common mouth diseases caused by its members, predisposing factors and treatment, and the potential for causing disseminated disease like their bacterial counterparts.
