A39.83
Meningococcal arthritis
Clinical Classification Guidelines
Medical Intelligence & Overview
Meningococcal arthritis is a joint infection caused by the bacteria Neisseria meningitidis, commonly known as meningococcus. This condition is a complication that can arise when the bacteria spread from the bloodstream to the joints, leading to inflammation. Recognized under ICD-10 code A39.83, meningococcal arthritis is relatively rare but requires prompt diagnosis and treatment to prevent joint damage and other serious health issues. It often occurs alongside meningococcal meningitis or septicemia but can also present as an isolated joint infection.
Causes & Symptoms
Clinical Causes: Infection with Neisseria meningitidis bacteria Bacterial spread through bloodstream, reaching the joints Close contact with someone infected with meningococcus Compromised immune system increasing susceptibility Recent respiratory infections or outbreaks of meningococcal disease
Key Symptoms: Severe joint pain, often sudden in onset Swelling and warmth in the affected joint Redness over the joint area Limited joint movement due to pain Fever and chills General feeling of illness or fatigue Potential signs of systemic infection, such as rash or headache
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical evaluation and laboratory tests. Physical examination can reveal joint swelling and tenderness. Blood tests may show signs of infection, such as elevated white blood cell count and inflammatory markers. Joint aspiration, where fluid is removed from the affected joint, helps identify Neisseria meningitidis bacteria through gram stain, culture, or PCR testing. Additional tests might include blood cultures and imaging studies like X-rays to assess joint damage.
Treatment Protocols: Treatment primarily consists of prompt antibiotic therapy suited for Neisseria meningitidis. Intravenous antibiotics are often administered initially to combat the bacteria effectively. Supportive care includes pain management with medications and rest for the affected joint. In some cases, hospitalization may be necessary for close monitoring and supportive care. Early treatment is crucial to prevent joint destruction and other complications. Follow-up care may involve physical therapy to restore joint function after infection resolution.
