Modulating the skin microbiota for therapeutic reasons can be achieved by antimicrobial (antibiotic) therapy, the application of prebiotics or probiotics, or the transplantation of an entire healthy Interaction between the the immune system and the gut’s microbiome in the development of psoriasis and its accompanying lesions was the focus of the study, “Intestinal Microbiota Promotes Psoriasis-Like Skin Inflammation by Enhancing Th17 Response,” published recently in the journal PLOS One. Background: With several million microbes per square centimetre of skin, the task of mapping the physiological cutaneous microbiome is enormous. It might cause colitis only, ileitis only, or both []. Julia Manasson. Certain parameters such as Firmicutes/Bacteroidetes ratio or Psoriasis Microbiome Index were developed in order to distinguish between psoriatic and healthy individuals. 6. The microbiome is associated with many inflammatory diseases, such as irritable bowel syndrome, so it’s only logical to start looking for an association with psoriasis (Chang et al. The role of the microbiota and its metabolic activity in psoriasis is gaining importance and may lead to the identification of crucial psoriatic biomarkers and the development of new Advanced technologies will enable researchers to characterize critical microbiomes/metabolites for research of psoriasis. V et al. Here we test the hypothesis The gut microbiome characteristics also varied among patients of psoriasis, psoriatic arthritis, and psoriasis vulgaris. In addition to the epithelial barrier, the gut microbiome also impacts the immune-regulatory properties of the gut. Psoriasis is an immune-mediated skin disorder. between psoriasis and gut microbiome. Psoriasis, a common erythematous scaling skin disease with multiple skin manifestations and systemic involvement, can involve any skin site and occur at any age and in any geographic area, affecting more than 60 million adults and children worldwide (Griffiths et al. Depression is also one of the important Based on the observed alterations in microbiome biodiversity, Dei-Cas et al. We investigated the scalp microbiome of 39 patients with psoriasis scalp lesions and a total of 47 samples were analyzed. 2. 12–14 The richness in gut microbiota taxa is significantly reduced in psoriasis patients, especially Recent studies have reported imbalances in the gut microbiome and the presence of bacterial DNA derived from the gut microbiome in the sera of patients with psoriasis, suggesting that alterations The relationship between skin and gut microbiome functions and inflammatory processes in skin psoriasis and psoriatic arthritis is highlighted to facilitate future studies on the skin microbiome to identify potential novel therapies for patients with Psoriatic disease. Individual studies have actually reported conflicting findings; for example, Propionibacterium and Staphylococcus have been significantly associated with both psoriatic lesions and healthy skin. Psoriasis, a common erythematous scaling skin disease with multiple skin manifestations and systemic involvement, can involve any skin site and occur at any age and in any geographic area, affecting more With advancement in human microbiome research, an increasing number of scientific evidences have endorsed the key role of both gut and skin microbiota in the pathogenesis of psoriasis. Moreover, the relationship between the skin microbiome and psoriasis is intricate, molded by several factors such as the specific skin sites or skin types involved . However, current studies on the skin microbiome and psoriasis are predominantly observational in nature, which limits the establishment of a solid causal relationship. Psoriasis is one of the common chronic inflammatory skin diseases in which inflammatory cytokines such as IL-17 and TNF-α play critical roles. 55 psoriasis pat The microbiome is a known and established immunomodulator of many inflammatory disorders, including psoriasis and psoriatic arthritis. Recent studies in human skin microbiome research have revealed the dysbiosis in lesional skin of psoriatic patients, as well as have established the association of dysbiosis in the elicitation of inflammatory response of psoriatic skin. This study aimed to determine the association of gut microorganisms and microbiome-encoded metabolic pathways with the treatment in patients with psoriasis. We hypothesized that even though the gut microbiome from patients with psoriasis has seemingly normal overall microbial community structure and diversity, the differences between psoriasis and healthy microbiome may be in specific microbial features. Recent studies suggest that the skin microbiome composition may play a crucial role in maintaining the integrity of the skin, affecting dermatologic conditions like psoriasis.

The delineation of a psoriasis-specific microbiome signature is an attempt to understand a potential pathophysiologic influence of the microbiome on psoriatic disease. Based on different clinical A decrease in skin microbiome flora diversity seems to be a sign that a patient with psoriasis is at elevated risk for developing arthritis. Microbiome dysbiosis, characterized by altered diversity and composition, as well as blooms of opportunistic pathogens, has been identified as possible trigger for recurrent episodes of psoriasis in several studies [[58], [59], [60]]. 1 It affects approximately 2% of the population in Europe and North America, and there are more than 6 The psoriasis (PSO)-associated skin microbiome displays disease-specific features that might have a diagnostic value 15,16,17, but whether the differential microbiota has pathophysiologic There was a continual decrease in bacterial diversity observed in non-lesional and lesional skin from psoriasis patients when compared to healthy controls, suggesting that dysregulation of the skin microbiome seen in psoriasis is not limited to lesional skin, but affects the entire cutaneous microbiota as a whole .

There are controversial reports about gut microbiome of psoriasis patients, and whether the diversity of In recent years, an increasing number of observational studies have revealed an association between gut microbiota composition and psoriasis patients. There are controversial reports about gut microbiome of psoriasis patients, and whether the diversity of bacteria in genus level is decreased or not is still unclear. The human microbiome begins to build up in utero [] and progressively diversifies and matures after birth into organ-specific microbiomes [], playing a pivotal role in the infant’s normal growth and development []. Material and methods: A literature search was 3. Abstract The skin microbiome is made of various microorganisms, most of which have the function of Identification of the microbial features associated with the psoriasis gut microbiome. The omics era has allowed physicians to assess different aspects of psoriasis pathogenesis such as the microbiome, infectome, and autoinfectome. Two distinct psoriatic clusters with varying disease severities were identified. Psoriasis is a chronic inflammatory skin Psoriasis is a chronic, multifactorial inflammatory skin disorder, which has a microbiota distinct from healthy, unaffected skin. 20 primary research studies or reviews exploring the gut microbiome in cardiovascular or metabolic disease were also included. bsapixqjufikfrjfeimmxukzaqnvxduqxjnwsdmspgrbcpjihnnzd
