Reactive arthritis induced by parasitic infestation
Annals of Internal Medicine
|February 1, 1981
Summary
Parasitic infections can trigger arthritis in some individuals. Treating the underlying parasitic infestation resolved joint symptoms and immune system abnormalities.
Area of Science:
- Immunology
- Rheumatology
- Infectious Diseases
Background:
- Parasitic infections are prevalent globally.
- Arthritis is a common condition with diverse etiologies.
- The link between parasitic infections and joint inflammation requires further elucidation.
Observation:
- Two patients developed polyarticular, symmetrical arthritis during Strongyloides stercoralis and Taenia saginata infestations.
- Joints showed seronegative and nonerosive changes radiologically.
- Abnormal humoral immunity, immune complexes, and immunoglobulin deposits were detected.
Findings:
- Specific antiparasitic treatment led to the resolution of arthritis symptoms.
- Immune complex formation in synovial fluid and tissue is implicated in pathogenesis.
- Nonsteroidal anti-inflammatory drugs were ineffective in managing the parasitic arthritis.
Implications:
- Parasitic infections can induce immune complex-mediated arthritis in susceptible individuals.
- Diagnosis and treatment of parasitic infections are crucial for managing specific arthritis types.
- This study highlights the complex interplay between host immunity and parasitic agents in disease manifestation.

01:29Autoimmune Disorders
2.4K
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.

1.0K
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...

59
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

01:19Encephalitis l: Introduction
15
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

35
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...

01:19Hypersensitivity Reactions: Immune-Complex Reactions
269
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum...
