Progress in the relationship between intestinal fungal dysbiosis and digestive system tumors / 中华微生物学和免疫学杂志

Intestinal fungal dysbiosis is closely associated with the development and progression of many diseases including tumors. The disruption of fungal communities is involved in tumorigenesis and progression through inducing aberrant host immune responses and the production of certain metabolites as well as promoting the establishment of interactions with bacteria. Fungal dysbiosis is a potential marker for early detection of digestive tumors and a factor influencing the efficacy of tumor therapy. Studying the association between gut fungi and digestive tumors may facilitate the prevention, diagnosis and treatment of digestive tumors.

Colonización fúngica y síntomas gastrointestinales en niños con trastorno del espectro autista y neurotípicos / Fungical colonization and gastrointestinal symptoms in children with autistic spectrum disorder and neurotipic

Introducción: los síntomas digestivos pudiesen presentarse por colonización fúngica, alteraciones en la barrera intestinal y microbiota bacteriana, enfermedades alérgicas, autoinmunes y disbiosis. Objetivo: investigar la presencia de colonización fúngica y síntomas gastrointestinales en niños con trastorno del espectro autista y neurotípicos. Metodología: estudio prospectivo, aleatorio, comparativo y transversal Grupo A: niños con trastorno del espectro Autista (TEA) y grupo B: niños neurotípicos. variables: edad, sexo, síntomas gastrointestinales, perfil de disbiosis básico e identificación de hongos. Resultados: grupo A, 28 niños, 7,11+3,07 años (rango 2-13), 25 (89,28%) masculino. Síntomas: distensión abdominal, estreñimiento y flatulencia fétida; grupo B, 16 niños, 5,55+3,20 años (rango 2-11), 10 (62,25%) femenino. Síntomas: dolor abdominal y alteración del patrón evacuatorio. Se encontró mayor colonización fúngica en el grupo A, 22/28 (78,57%) con respecto al grupo B, 5/16 (31,25%), p=0.0034. Se obtuvo microbiota fúngica 11/28 como comensal y 11/28 patógena en el grupo A y grupo B, 3/16 comensal y 2/16 como patógeno, diferencia significativa, p=0.0103. La cándida fue el hongo más aislado. Grupo A, 20/22 (90,90%) y grupo B, 5/16 (31,25%). disbiosis fúngica, 11/22 del grupo A, 5 (45,45%) grado III, 4 (36,36%) grado II y 2 (18,18%) grado I, y grupo B, 2/5 grado I, no se encontraron diferencias p=0,538. Hubo disbiosis simultánea fúngica y bacteriana, sin diferencias entre los grupos, p=0,5366. Conclusiones: los niños con TEA y síntomas digestivos presentan con mayor frecuencia colonización fúngica y disbiosis que los niños neurotípicos. un nuevo abordaje se encuentra al alcance con el estudio de la microbiota fúngica, además de la bacteriana(AU)

Introduction: digestive symptoms may occur due to fungal colonization, alterations in the intestinal barrier, bacterial microbiota, allergic and autoimmune diseases, and dysbiosis. Objective: to investigate the presence of fungal colonization and gastrointestinal symptoms in children with Autism spectrum disorder (ASD) and neurotypic children. Methodology: Prospective, randomized, comparative and cross-sectional study, Group A: children with Asd) and group B: neurotypic children. variables: age, sex, gastrointestinal symptoms, basic dysbiosis profile and fungal identification. Results: group A, 28 children, 7.11 + 3.07 years (range 2-13), 25 (89.28%) male. symptoms: abdominal distension, constipation and fetid flatulence; group B, 16 children, 5.55 + 3.20 years (range 2-11), 10 (62.25%) female. symptoms: abdominal pain and abnormal evacuation pattern. Greater fungal colonization was found in group A, 22/28 (78.57%) vs group B, 5/16 (31.25%), p = 0.0034. Fungic microbiota 11/28 was obtained as commensal and 11/28 as pathogenic in group A (group B, 3/16 commensal and 2/16 pathogen), p = 0.0103. candida was the most isolated fungus. Group A: 20/22 (90.90%), Group B: 5/16 (31.25%). Fungal dysbiosis, 11/22 group A, 5 (45.45%) grade III, 4 (36.36%) grade II and 2 (18.18%) grade I; group B, 2/5 grade I, no differences were found p = 0.1538. there was simultaneous fungal and bacterial dysbiosis, without differences between the groups, p = 0.5366. Conclusions: children with Asd and digestive symptoms have more frequent fungal colonization and dysbiosis than neurotypic children. A new approach is within reach with the study of the fungal microbiota, in addition to the bacterial one(AU)

Effect of intestinal fungal dysbiosis on corneal wound healing in mice / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To investigate the effect of intestinal fungal dysbiosis induced by antifungal drug on corneal wound healing in mice.<p>METHODS: Male C57BL/6J mice(free of eye disease)were divided into two groups randomly: control(Ctrl)group and amphotericin B treated(Amph)group, The Ctrl group was given a normal diet, and the Amph group was supplemented with amphotericin B to induce intestinal fungal dysbiosis. After 4wk intervention, corneal epithelial trauma was implemented in both groups. Corneal fluorescein staining was used to evaluate the corneal wound area dynamically. Immunofluorescence staining was applied to observe the changes of corneal epithelial cells and inflammatory cells. HE staining was used to assess the change of corneal thickness.<p>RESULTS: Compared with Ctrl group, Amph group had delayed re-epithelialization rate and wound repair, less inflammatory cells and thinner corneal.<p>CONCLUSION: Intestinal fungal dysbiosis delays the corneal wound healing, leading to a weak inflammatory response.
