Successful Synergistic Use of Gabapentin With Other Antiepileptic Drugs in the Management of Lance-Adams Syndrome Complicated by Alcohol Withdrawal Seizures: A Case Report.

Objective: Lance-Adams syndrome is a rare and debilitating disorder characterized by successful cardiopulmonary resuscitation resulting in myoclonus activity. Alcohol withdrawal seizures from alcohol use disorder may further exacerbate Lance-Adams syndrome. We aim to present a case of Lance-Adams syndrome complicated by alcohol withdrawal seizures and successfully treated with a combination of valproate, clonazepam, and gabapentin.

Materials and methods: The patient's electronic medical record, direct patient care experiences, and a comprehensive literature search were used for this case report. We report a 41-year-old male patient with Lance-Adams syndrome with concurrent alcohol use disorder. Treatment was improved when adding gabapentin for alcohol use disorder treatment, alongside combination antiepileptic therapy. A PubMed search was conducted to examine Lance-Adams syndrome case reports of successful combination antiepileptic therapy, with a secondary evaluation of patients with concurrent alcohol use disorder.

Results: The literature search yielded 18 articles, which resulted in 21 individual cases in which combination antiepileptic drug therapy was successful in treating myoclonus secondary to Lance-Adams syndrome; however, none of the case reports utilized gabapentin synergistically. One case described Lance-Adams syndrome complicated by alcohol consumption and similar to our patient, the patient used alcohol to abolish myoclonic activity.

Conclusions: To the best of our knowledge, this is the first case report documenting a patient with Lance-Adams syndrome and concurrent alcohol use disorder, with a positive effect of gabapentin use. Gabapentin, when used for alcohol use disorder treatment, may be an appropriate adjunct agent in the management of patients receiving combination antiepileptic therapy for the treatment of Lance-Adams syndrome.
