Respiratory Syncytial Virus in a Child With Dravet Syndrome: A Case Report

The objective of this case report is to describe and document a case of respiratory syncytial virus (RSV) in a pediatric patient with Dravet syndrome (DS), also known as severe myoclonic epilepsy of infancy. Febrile seizures are often a complication in a patient with DS and can lead to status epilepticus, necessitating measures to prevent triggers such as fever, electrolyte imbalance, or dehydration. An increased awareness and understanding of DS can facilitate the identification of warning signs. A two-year-old female with a past medical history of DS with focal and generalized features presented to the pediatric emergency department (ED) with a five-day history of cough, fever, and decreased oral intake. The patient's parents accompanied her and expressed concerns regarding the risk of seizures associated with a rise in body temperature, as they had been alternating between acetaminophen and ibuprofen to manage her fever with a maximum recorded temperature of 101.5℉. She exhibited signs of increased work of breathing, necessitating the administration of supplemental oxygen via nasal cannula. Blood samples were obtained and resulted in the development of metabolic acidosis. A respiratory panel confirmed the presence of an RSV infection, promoting the administration of breathing treatment with albuterol and ipratropium bromide. The patient was admitted for dehydration and was started on ½ normal saline/potassium chloride 20 mEq at 40 mL/hr. Additionally, her home medication regimen was resumed to minimize the risk of seizures. Given the patient's complications and increased risk of seizure, she was transferred to higher-level care where her status improved after the placement of a percutaneous endoscopic gastrostomy (PEG). This case underscores the complexities involved in managing patients with DS, particularly when complicated by respiratory illness and electrolyte imbalances that can lower the seizure threshold. This patient received a combination of diet and medications to prevent seizures, as well as allow for recovery and correction of the underlying metabolic acidosis. The transfer to a higher level of care in this case was necessary to allow for the specialized resources and expertise needed to handle this case.
