ICD-10: G00.2

Streptococcal meningitis, classified under ICD-10 code G00.2, is a specific type of bacterial meningitis caused by Streptococcus species, particularly Streptococcus pneumoniae. This condition is characterized by the inflammation of the protective membranes covering the brain and spinal cord, known as the meninges. Below is a detailed overview of the clinical description, symptoms, diagnosis, and treatment options for this condition.

Clinical Description

Etiology

Streptococcal meningitis is primarily caused by the bacterium Streptococcus pneumoniae, which is a common pathogen responsible for various infections, including pneumonia and otitis media. In some cases, other Streptococcus species may also be implicated, but S. pneumoniae is the most prevalent cause of bacterial meningitis in adults and children[1][2].

Pathophysiology

The infection typically begins when the bacteria invade the bloodstream or the central nervous system (CNS) through adjacent structures, such as the ears or sinuses. Once in the CNS, the bacteria multiply and trigger an inflammatory response, leading to the classic symptoms of meningitis. The inflammation can result in increased intracranial pressure and potential complications, such as seizures or neurological deficits[1].

Symptoms

The clinical presentation of streptococcal meningitis can vary, but common symptoms include:

• Fever: Often high and persistent.
• Headache: Severe and often described as the worst headache ever experienced.
• Stiff Neck: Inability to flex the neck forward due to pain and rigidity.
• Photophobia: Sensitivity to light.
• Altered Mental Status: Ranging from confusion to coma in severe cases.
• Nausea and Vomiting: Commonly associated with increased intracranial pressure.
• Skin Rash: In some cases, a petechial or purpuric rash may be present, indicating a more severe systemic infection[1][2].

Diagnosis

Clinical Evaluation

Diagnosis of streptococcal meningitis typically involves a combination of clinical evaluation and laboratory tests. Key steps include:

• History and Physical Examination: Assessing symptoms and neurological status.
• Lumbar Puncture: This procedure is critical for obtaining cerebrospinal fluid (CSF) for analysis. In cases of streptococcal meningitis, the CSF may show elevated white blood cell counts, predominantly lymphocytes, elevated protein levels, and decreased glucose levels[1][2].
• Blood Cultures: To identify the causative organism, blood cultures are often performed, which can help confirm the presence of Streptococcus pneumoniae.

Imaging Studies

In some cases, imaging studies such as CT or MRI may be performed to rule out other conditions, such as brain abscesses or other structural abnormalities that could complicate the clinical picture[1].

Treatment

Antibiotic Therapy

The cornerstone of treatment for streptococcal meningitis is prompt initiation of appropriate intravenous antibiotics. Commonly used antibiotics include:

• Ceftriaxone: A broad-spectrum cephalosporin effective against many strains of Streptococcus pneumoniae.
• Vancomycin: Often added to cover for resistant strains of S. pneumoniae and other potential pathogens[1][2].

Supportive Care

In addition to antibiotic therapy, supportive care is crucial. This may include:

• Fluid Management: To maintain hydration and electrolyte balance.
• Pain Management: To alleviate headache and discomfort.
• Monitoring: Close observation for potential complications, such as seizures or increased intracranial pressure.

Conclusion

Streptococcal meningitis is a serious medical condition that requires immediate attention and treatment. Early diagnosis and appropriate antibiotic therapy are essential to improve outcomes and reduce the risk of complications. Given the potential severity of the disease, awareness of its symptoms and prompt medical intervention are critical for affected individuals. If you suspect meningitis, it is vital to seek medical care immediately to ensure timely diagnosis and treatment[1][2].
