M02.372
Reiter's disease, left ankle and foot
Clinical Classification Guidelines
Medical Intelligence & Overview
Reiter's disease, also known as reactive arthritis, is a condition characterized by inflammation that occurs as a reaction to a previous infection in the body. When it affects the left ankle and foot, it can cause pain, swelling, and mobility issues. This type of arthritis often develops after infections in the urinary or gastrointestinal systems and primarily impacts weight-bearing joints, including the ankles and feet, leading to discomfort and functional impairment.
Causes & Symptoms
Clinical Causes: Infection with bacteria such as Chlamydia trachomatis (sexually transmitted infections) Gastrointestinal infections caused by bacteria like Salmonella, Shigella, Yersinia, or Campylobacter Genetic predisposition, especially with a positive HLA-B27 blood test Environmental factors that trigger the immune response post-infection
Key Symptoms: Pain and swelling in the affected joints, notably the left ankle and foot Warmth and redness around the joints Stiffness, especially after periods of rest Lower limb pain that worsens with activity Enthesitis — inflammation where tendons and ligaments attach to bones Possible skin rashes, ulcers, or eye inflammation (less common)
Diagnostic & Treatment
Diagnosis Path: Physical examination to assess joint swelling, tenderness, and range of motion Blood tests to identify inflammation markers such as ESR and CRP HLA-B27 genetic testing, which may be positive in some cases Joint fluid analysis to rule out other types of arthritis and detect infectious agents Urine or stool tests to identify recent bacterial infections Imaging studies like X-rays or MRI to evaluate joint damage and inflammation
Treatment Protocols: Nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve pain and swelling Physical therapy and regular exercise to maintain joint mobility and strength Corticosteroids, either orally or injected directly into affected joints, to control severe inflammation Antibiotic therapy in cases where persistent infection is identified Disease-modifying antirheumatic drugs (DMARDs) may be considered in chronic or severe cases Lifestyle modifications, including rest during flare-ups and avoiding activities that worsen symptoms
