Autoimmune Disorders01:29

Autoimmune Disorders

671
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Inflammatory Response I: Vascular and Cellular01:30

Inflammatory Response I: Vascular and Cellular

12.4K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Inflammatory Bowel Disease II: Crohn's Disease

382
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory Bowel Disease I: Ulcerative Colitis

321
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

540
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Rheumatic Heart Disease I: Introduction

39
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Área de la Ciencia:

  • Inmunología
  • Reumatología
  • La genética

Sus antecedentes:

  • Las enfermedades autoinflamatorias (AID) implican una desregulación innata del sistema inmunológico.
  • La vasculitis en AID es frecuentemente sub-reconocida y mal diagnosticada.
  • Los datos recientes desde 2016 destacan los síndromes y conocimientos recién identificados.

Objetivo del estudio:

  • Explorar la relación entre las enfermedades autoinflamatorias y la vasculitis.
  • Centrarse en los síndromes identificados recientemente y los datos actualizados.
  • Para revisar las manifestaciones vasculares en varios AID.

Principales métodos:

  • Revisión de la literatura de las publicaciones recientes (desde 2016).
  • Análisis de las características clínicas, genéticas e histológicas de las AID con vasculitis.
  • Discusión de las vías inflamatorias subyacentes y las mutaciones genéticas.

Principales resultados:

  • La vasculitis ocurre en diversas AID, incluida la fiebre mediterránea familiar, DADA2, VEXAS y CAPS.
  • La afectación vascular varía desde los hallazgos cutáneos hasta la vasculitis sistémica.
  • Los mecanismos incluyen IL-1β, sobreactivación de NF-κB y nuevas mutaciones genéticas.

Conclusiones:

  • El reconocimiento temprano de la vasculitis en AID es crucial para el diagnóstico, especialmente en casos atípicos.
  • Se recomiendan pruebas genéticas para casos sospechosos.
  • La comprensión de patrones distintos guía el manejo con productos biológicos o trasplante de células madre para obtener mejores resultados.
