Insights

Reactive arthritis (ReA) following bacterial enteric infections is a significant health issue in the US. Further research is needed to define ReA and understand its full impact.

Area of Science:

  • Infectious Diseases
  • Rheumatology
  • Epidemiology

Background:

  • Bacterial enteric infections lead to considerable illness in the United States, including long-term complications.
  • Reactive arthritis (ReA) is an incompletely defined condition that can arise after infections like Salmonella, Shigella, Campylobacter, and Yersinia.
  • Existing research on ReA following enteric infections in the US is limited.

Purpose of the Study:

  • To review clinical and epidemiologic investigations of Reactive Arthritis (ReA) after bacterial enteric infections in the United States.
  • To highlight the need for clearer definitions and further population-based studies to understand the burden of ReA.

Main Methods:

  • Review of clinical and epidemiologic literature on Reactive Arthritis (ReA) following bacterial enteric infections in the US.
  • Analysis of existing population-based studies and outbreak investigations.

Main Results:

  • Only two population-based studies on ReA following enteric infection have been conducted in the US.
  • ReA following Campylobacter and Yersinia outbreaks has not been investigated.
  • Past studies on Shigella and Salmonella outbreaks focused on the outdated concept of Reiter's syndrome rather than ReA.

Conclusions:

  • A clearer definition of Reactive Arthritis (ReA) is essential before further epidemiologic studies can accurately determine its burden.
  • Additional research is required to fully understand the scope and impact of ReA following bacterial enteric infections in the US.

Rheumatic Heart Disease I: Introduction

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...
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 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 I: Introduction01:26

Inflammatory Bowel Disease I: Introduction

Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows “skip lesions” in which...

Gastritis-I: Introduction and Types

Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...

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...
