Utilizing Infantile Spasm Seizure Activity as a Baseline Vital in the Setting of Acute Pseudomonas aeruginosa Pneumonia.

The objective of this case report is to describe and document a decrease in seizure activity in a 16-year-old female with a past medical history of Aicardi syndrome (AS) and infantile spasms (IS) while being treated for acute pneumonia with pleural effusion. This patient presented to the pediatric emergency department with a chief complaint of fever, tachycardia, increased nasal secretions, and oxygen requirement at home. She was admitted to the general pediatric medical floor for treatment of an adenovirus infection due to her having a complex medical history and her being medically unstable. On hospital admission day 1, she developed post-viral pneumonia. She subsequently had three days of complete clinical seizure cessation without changing her anti-epileptic medications. It was not until the symptomatology related to her pneumonia improved that her seizure activity returned to its baseline frequency. The treating team discovered that the decrease in her frequency of seizure activity related to periods of increased physiologic stress was not new. Her mother reported that she has used the relationship between her daughter's seizures and any acute illness to gauge how her daughter was "feeling" medically. Three weeks prior to this hospital admission, her mother reported that her daughter's seizures ceased for two days during a period in which it was determined that the patient was having renal colic and passed a renal stone. This phenomenon, the decrease in the frequency of seizure activity related to periods of increased physiologic stress, could help primary caretakers assess when significant, new comorbid conditions are present and could aid in the primary assessment of physical health in a particular patient population who are unable to verbalize their current medical status. Utilizing seizure activity as an at-home vital sign could help caretakers recognize when their patient is under an elevated physiologic stress condition. Recognizing the relationship between seizure frequency and acute illness could also help diagnostically, as ISs are difficult to both diagnose and manage. Also, future research on this possible association could explore more understanding of IS and pathophysiology of such phenomenon.
