ICD-10: A54.42

Gonococcal arthritis, classified under ICD-10 code A54.42, is a specific type of arthritis caused by the Neisseria gonorrhoeae bacterium, which is the same pathogen responsible for gonorrhea. This condition is characterized by joint inflammation and can occur as a complication of a gonococcal infection, particularly in sexually active individuals.

Clinical Description

Pathophysiology

Gonococcal arthritis typically arises from disseminated gonococcal infection (DGI), where the bacteria spread from the initial site of infection (often the urogenital tract) into the bloodstream, leading to joint involvement. The infection can affect one or multiple joints, with the knee, wrist, and ankle being the most commonly affected sites.

Symptoms

Patients with gonococcal arthritis may present with:
- Joint Pain and Swelling: Often acute and can affect one or multiple joints.
- Fever: Systemic symptoms may include fever and malaise.
- Skin Lesions: Some patients may develop skin lesions, which can appear as pustules or maculopapular rashes, particularly in cases of disseminated infection.
- Limited Range of Motion: Affected joints may exhibit reduced mobility due to pain and swelling.

Diagnosis

Diagnosis of gonococcal arthritis involves:
- Clinical Evaluation: A thorough history and physical examination to assess joint involvement and systemic symptoms.
- Laboratory Tests: Synovial fluid analysis from the affected joint can reveal the presence of Neisseria gonorrhoeae. Cultures, polymerase chain reaction (PCR) tests, and serological tests may also be employed to confirm the diagnosis.
- Imaging Studies: X-rays or MRI may be used to assess joint damage or rule out other causes of arthritis.

Treatment

The management of gonococcal arthritis typically includes:
- Antibiotic Therapy: Prompt initiation of appropriate antibiotics is crucial. Common regimens may include ceftriaxone or azithromycin, depending on local resistance patterns and guidelines.
- Joint Aspiration: In cases of significant effusion, aspiration may be performed to relieve pressure and obtain synovial fluid for analysis.
- Supportive Care: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be used to manage pain and inflammation.

Prognosis

With timely diagnosis and treatment, the prognosis for patients with gonococcal arthritis is generally favorable. However, if left untreated, the condition can lead to chronic joint damage and complications.

Conclusion

ICD-10 code A54.42 encapsulates the clinical significance of gonococcal arthritis as a serious manifestation of gonococcal infection. Awareness of its symptoms, diagnostic criteria, and treatment options is essential for healthcare providers to ensure effective management and prevent long-term complications associated with this condition.

Gonococcal arthritis, classified under ICD-10 code A54.42, is a type of inflammatory arthritis caused by the Neisseria gonorrhoeae bacterium. This condition is part of a broader spectrum of gonococcal infections and is characterized by specific clinical presentations, signs, symptoms, and patient characteristics.

Clinical Presentation

Gonococcal arthritis typically presents as an acute or subacute inflammatory arthritis, often affecting one or more joints. The most commonly involved joints include the knees, ankles, wrists, and fingers. The condition can occur in two forms:

1. Disseminated Gonococcal Infection (DGI): This occurs when the bacteria spread from the site of infection (often the genitourinary tract) to the bloodstream, leading to joint involvement.
2. Localized Gonococcal Arthritis: This form is characterized by infection localized to a specific joint without systemic involvement.

Signs and Symptoms

The signs and symptoms of gonococcal arthritis can vary but typically include:

• Joint Pain and Swelling: Patients often experience significant pain, swelling, and tenderness in the affected joints, which may be unilateral or bilateral[1].
• Erythema and Warmth: The skin over the affected joint may appear red and feel warm to the touch, indicating inflammation[1].
• Limited Range of Motion: Due to pain and swelling, patients may have difficulty moving the affected joint[1].
• Systemic Symptoms: Patients may also present with fever, chills, and malaise, particularly in cases of disseminated infection[1][2].
• Skin Lesions: In some cases, patients may develop pustular skin lesions, which can be indicative of DGI[2].

Patient Characteristics

Certain patient characteristics can influence the presentation and diagnosis of gonococcal arthritis:

• Demographics: Gonococcal arthritis is more prevalent in sexually active individuals, particularly those aged 15 to 29 years. It is also more common in women than men, often due to the higher incidence of asymptomatic infections in females[2][3].
• Risk Factors: Patients with multiple sexual partners, a history of sexually transmitted infections (STIs), or those who engage in unprotected sexual practices are at increased risk for gonococcal infections and subsequent arthritis[3].
• Comorbidities: Individuals with underlying conditions such as HIV, which can compromise the immune system, may be more susceptible to severe manifestations of gonococcal arthritis[3].

Conclusion

Gonococcal arthritis, represented by ICD-10 code A54.42, is a significant clinical condition that requires prompt recognition and treatment. Understanding its clinical presentation, signs, symptoms, and patient characteristics is crucial for healthcare providers to ensure timely diagnosis and management. Early intervention can prevent complications and improve patient outcomes, highlighting the importance of awareness regarding this condition in sexually active populations.

For further management, healthcare providers should consider appropriate diagnostic tests, including joint aspiration and culture, as well as systemic antibiotic therapy tailored to the patient's specific needs and clinical context[1][2].
