Antiepileptic Drugs and Influenza A Infection Complicated with Severe Thrombocytopenia.

Background: Patients with epilepsy often require long-term antiepileptic medications, which can affect hematological parameters. Influenza (H1N1) infection is known to potentially cause thrombocytopenia. This case examines the clinical implications of a 29-year-old female patient with epilepsy who developed influenza and significant platelet reduction.

Methods: A 29-year-old female patient with a history of epilepsy presented with fever lasting three days. She was undergoing treatment with multiple antiepileptic drugs, including levetiracetam, clonazepam, and carbamazepine. Comprehensive laboratory tests were performed to assess her complete blood count, liver and kidney function and to confirm influenza infection.

Results: The patient displayed symptoms of fever, cough, and fatigue. Laboratory tests revealed a platelet count of 28.0 x 109/L, indicating severe thrombocytopenia. Influenza A (H1N1) was confirmed via PCR testing. The patient was started on antiviral therapy and supportive care. During the treatment, the patient's fever decreased and her general condition improved. A week later, her platelet count was back to its previous level, while still low.

Conclusions: This case emphasizes the importance of regular platelet monitoring for patients on long-term antiepileptic drugs, particularly during H1N1 virus infections.
