B27.19

Clinical Causes: Primary infection with cytomegalovirus, which is part of the herpesvirus family Reactivation of latent CMV infection in immunocompromised individuals Transmission through body fluids such as saliva, blood, urine, semen, or breast milk Close personal contact, including kissing or sexual activity Organ transplantation or blood transfusions in rare cases

Key Symptoms: Fatigue and weakness Fever and chills Sore throat and swollen lymph nodes Hepatomegaly (enlarged liver) Splenomegaly (enlarged spleen) Muscle aches and malaise Headache Possible jaundice or yellowing of the skin and eyes in severe cases Rash or skin changes (less common)

Diagnosis Path: Diagnosing cytomegaloviral mononucleosis with complications involves a combination of clinical evaluation and laboratory tests. Healthcare providers may perform: - Blood tests to detect CMV-specific antibodies or viral DNA - Complete blood count (CBC) to assess white blood cell levels - Liver function tests to evaluate hepatomegaly and liver health - Imaging studies such as ultrasound or CT scans if organ enlargement is suspected Since symptoms can resemble other illnesses, confirmatory testing for CMV is essential for accurate diagnosis.

Treatment Protocols: Treatment primarily focuses on managing symptoms and monitoring for complications. Specific antiviral medications, such as ganciclovir or valganciclovir, may be considered in cases where the immune system is severely compromised or organ involvement is significant. Supportive care measures include: - Rest and adequate hydration - Over-the-counter pain relievers for discomfort - Avoidance of contact sports or activities that could cause injury to an enlarged spleen or liver In healthy individuals, the immune system typically clears the infection without the need for targeted therapy. Patients with weakened immunity or severe complications may require specialized medical intervention and closer observation.
