ICD-10: B27.19

Cytomegaloviral mononucleosis, classified under ICD-10 code B27.19, refers to a specific viral infection caused by the cytomegalovirus (CMV) that presents with symptoms similar to those of infectious mononucleosis. This condition is particularly notable for its potential complications, which can vary in severity and impact.

Clinical Description

Overview of Cytomegaloviral Mononucleosis

Cytomegaloviral mononucleosis is characterized by a constellation of symptoms that may include:

• Fever: Often a prominent symptom, indicating an active immune response.
• Fatigue: Patients frequently report significant tiredness that can last for weeks.
• Sore Throat: Similar to other forms of mononucleosis, a sore throat is common.
• Lymphadenopathy: Swelling of lymph nodes, particularly in the neck and armpits.
• Hepatosplenomegaly: Enlargement of the liver and spleen may occur, which can be detected through physical examination or imaging.

Complications

The designation "with other complication" in the ICD-10 code B27.19 indicates that the patient may experience additional health issues stemming from the primary infection. These complications can include:

• Neurological Issues: In some cases, CMV can lead to neurological complications such as meningitis or encephalitis, which may require further medical intervention.
• Hematological Complications: The virus can affect blood cell production, leading to conditions like thrombocytopenia (low platelet count) or hemolytic anemia.
• Gastrointestinal Symptoms: Some patients may experience gastrointestinal complications, including hepatitis or colitis.
• Immunocompromised States: Individuals with weakened immune systems, such as those with HIV/AIDS or organ transplant recipients, are at higher risk for severe manifestations of CMV infection.

Diagnosis and Management

Diagnosis of cytomegaloviral mononucleosis typically involves:

• Serological Testing: Detection of CMV-specific antibodies (IgM and IgG) can help confirm the diagnosis.
• Polymerase Chain Reaction (PCR): This test can identify CMV DNA in blood or other body fluids, providing a more definitive diagnosis.

Management of the condition often focuses on supportive care, including:

• Hydration: Ensuring adequate fluid intake to combat fever and fatigue.
• Pain Management: Use of analgesics for sore throat and body aches.
• Monitoring: Regular follow-up to assess for complications, especially in high-risk patients.

In cases where complications arise, more aggressive treatment may be necessary, including antiviral medications or hospitalization for severe manifestations.

In cases where complications arise or in immunocompromised patients, antiviral medications may be indicated. The most commonly used antiviral for CMV is:

• Ganciclovir: This medication is effective in reducing the viral load and managing severe manifestations of CMV infection. It is typically administered intravenously in a hospital setting for patients with significant complications.

Other antiviral options include:

• Valganciclovir: An oral prodrug of ganciclovir, used for outpatient management in less severe cases.
• Foscarnet: This may be used in cases of ganciclovir resistance or when patients cannot tolerate ganciclovir.

3. Management of Complications

If the patient presents with specific complications, targeted treatment is necessary. For example:

• Hepatitis: Monitoring liver function tests and providing supportive care, including possible antiviral therapy if liver involvement is severe.
• Pneumonia: Antibiotics may be required if a secondary bacterial infection is suspected, along with supportive respiratory care.

4. Monitoring and Follow-Up

Regular follow-up is crucial to monitor the patient's recovery and manage any emerging complications. This may involve:

• Blood Tests: To assess liver function, viral load, and overall health status.
• Imaging Studies: If respiratory or other organ complications are suspected.

5. Preventive Measures

For immunocompromised patients, preventive strategies are essential to avoid CMV reactivation or reinfection. This may include:

• Prophylactic Antivirals: In high-risk patients, especially those undergoing organ transplantation or chemotherapy.
• Education: Informing patients about hygiene practices to reduce the risk of CMV transmission.

Conclusion

Cytomegaloviral mononucleosis with complications requires a multifaceted treatment approach that includes supportive care, antiviral therapy, and careful monitoring of complications. The management strategy should be tailored to the individual patient's needs, particularly in the context of their overall health and any underlying conditions. Regular follow-up is essential to ensure a full recovery and to address any complications that may arise during the course of the illness.
