Resumen

Este estudio encontró patrones microbianos de la piel distintos en pacientes con atrofia múltiple del sistema (MSA), que difieren de la enfermedad de Parkinson y los controles sanos. Estos cambios microbianos se correlacionan con la gravedad de los síntomas de MSA, lo que sugiere una relación entre la enfermedad y las alteraciones del microbioma de la piel.

Área de la Ciencia:

Microbiología
Neurología
Dermatología

Sus antecedentes:

La atrofia sistémica múltiple (MSA) es un trastorno neurodegenerativo.
Se observan cambios en la fisiología de la piel en la MSA.
El impacto de la MSA en la microbiota de la piel no se comprende bien.

Objetivo del estudio:

Investigar las diferencias en la microbiota cutánea entre los pacientes con MSA, los pacientes con enfermedad de Parkinson y los controles sanos.
Determinar si las diferencias microbianas de la piel en la MSA se correlacionan con la gravedad de la enfermedad.

Principales métodos:

Se realizó la secuenciación del ARNr 16S en muestras de piel de los sitios cervical y axilar.
Se recogieron muestras de individuos con ASM, enfermedad de Parkinson y grupos de control.
Se analizaron patrones microbianos y se correlacionaron con los síntomas clínicos.

Principales resultados:

Se identificaron patrones microbianos cutáneos distintos entre los grupos de MSA, enfermedad de Parkinson y control.
Estos patrones microbianos permitieron una clasificación precisa de las cohortes.
Se encontraron asociaciones significativas entre las alteraciones microbianas y los síntomas clínicos en pacientes con MSA.

Conclusiones:

La composición de la microbiota cutánea difiere significativamente en la atrofia de sistemas múltiples.
Estas alteraciones microbianas están relacionadas con la presentación clínica y la gravedad de la MSA.
Los hallazgos sugieren un papel potencial para el microbioma de la piel en la patogénesis o progresión de la MSA.

Skin Diseases and Disorders

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Fungal Phylum Microsporidia

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Changes in Skin Color: Clinical Perspectives

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Role of Skin in Vitamin D Synthesis

Role of Skin in Vitamin D Synthesis

The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...
