Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Autoimmune Disorders01:29

Autoimmune Disorders

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.

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

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...
Inflammatory Bowel Disease III: Crohn's Disease01:25

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
Inflammatory Bowel Disease II: Crohn's Disease01:30

Inflammatory Bowel Disease II: Crohn's Disease

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 transmural...
Inflammatory Bowel Disease II: Ulcerative Colitis01:20

Inflammatory Bowel Disease II: Ulcerative Colitis

Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...

Area of Science:

  • Immunology
  • Genetics
  • Bone Metabolism

Background:

  • Autoinflammatory bone disorders are marked by chronic non-infectious osteomyelitis and bone resorption, stemming from innate immune system dysregulation.
  • Chronic non-bacterial osteomyelitis (CNO) is the most prevalent subtype, exhibiting diverse clinical presentations and an undetermined pathophysiology.
  • Recent advancements in understanding sterile bone inflammation have emerged from studying rare monogenic inflammatory diseases.

Purpose of the Study:

  • To review current knowledge on chronic non-bacterial osteomyelitis (CNO) and related genetic bone disorders.
  • To explore how insights from monogenic autoinflammatory bone diseases can elucidate CNO pathogenesis.
  • To highlight the role of genetic causes in bone metabolism and chronic inflammation.

Main Methods:

  • Literature review of autoinflammatory bone disorders.
  • Analysis of genetic causes affecting bone metabolism.
  • Discussion of inflammatory pathways in bone resorption.

Main Results:

  • Majeed syndrome, cherubism, hypophosphatasia, and primary hypertrophic osteoarthropathy have identified genetic origins linked to bone metabolism and inflammation.
  • The precise pathophysiology of CNO remains elusive.
  • Monogenic diseases provide a framework for understanding sterile bone inflammation.

Conclusions:

  • Understanding monogenic autoinflammatory bone diseases offers crucial insights into the pathogenesis of bone inflammation and resorption.
  • Further research into distinct inflammatory pathways is essential for deciphering CNO and related conditions.
  • Genetic factors play a significant role in the development of chronic bone inflammation.
