ICD-10: A54.81

Gonococcal meningitis

Additional Information

Description

Gonococcal meningitis, classified under ICD-10 code A54.81, is a rare but serious infection caused by the bacterium Neisseria gonorrhoeae, which is primarily known for causing gonorrhea. This condition occurs when the bacteria invade the central nervous system, leading to inflammation of the protective membranes covering the brain and spinal cord (meninges).

Clinical Description

Etiology

Gonococcal meningitis is a result of disseminated gonococcal infection (DGI), where Neisseria gonorrhoeae spreads from the urogenital tract to the bloodstream and subsequently to the meninges. This can occur in individuals with untreated gonorrhea, particularly in those with risk factors such as immunocompromised states or concurrent infections.

Symptoms

The clinical presentation of gonococcal meningitis can be similar to other forms of bacterial meningitis and may include:
- Fever: Often high and persistent.
- Headache: Severe and often described as the worst headache ever experienced.
- Stiff Neck: A hallmark sign of meningitis, indicating irritation of the meninges.
- Photophobia: Sensitivity to light.
- Altered Mental Status: Ranging from confusion to coma in severe cases.
- Nausea and Vomiting: Commonly associated with increased intracranial pressure.

Diagnosis

Diagnosis of gonococcal meningitis typically involves:
- Lumbar Puncture: Analysis of cerebrospinal fluid (CSF) is crucial. The CSF may show elevated white blood cell counts, predominantly neutrophils, and low glucose levels, which are indicative of bacterial meningitis.
- Culture and PCR Testing: CSF cultures can identify Neisseria gonorrhoeae, and polymerase chain reaction (PCR) testing can provide rapid and specific diagnosis.
- Blood Cultures: These may also be performed to detect the presence of the bacteria in the bloodstream.

Treatment

Immediate treatment is critical due to the potential for rapid deterioration. The standard treatment regimen includes:
- Antibiotics: Intravenous administration of ceftriaxone is commonly used, often in combination with azithromycin to cover potential co-infection with Chlamydia trachomatis.
- Supportive Care: This may include fluids, pain management, and monitoring for complications such as seizures or increased intracranial pressure.

Complications

If not treated promptly, gonococcal meningitis can lead to severe complications, including:
- Septic Shock: Resulting from systemic infection.
- Neurological Damage: Such as hearing loss, cognitive deficits, or seizures.
- Death: In severe cases, particularly if treatment is delayed.

Conclusion

Gonococcal meningitis is a critical condition that requires immediate medical attention. Awareness of its symptoms and prompt diagnosis and treatment are essential to improve outcomes. Given its association with sexually transmitted infections, public health measures focusing on prevention and education about gonorrhea are vital in reducing the incidence of this serious complication.

Clinical Information

Gonococcal meningitis, classified under ICD-10 code A54.81, is a rare but serious infection caused by the bacterium Neisseria gonorrhoeae.
