Abstract

Introduction: Valproic acid (VPA) is currently a drug that can be used in the prophylaxis of epilepsy, bipolar disorder, schizoaffective disorder, schizophrenia and migraine. Valproic acid poisoning can result in central nervous system depression, shock, acute hyperammonemia, cerebral edema, coma and death. In this case, we wanted to present a patient who was treated with levocarnitine, hemodialysis and meropenem due to severe VPA toxicity.
Case: A 41-year-old male patient was firstly brought to the emergency room and then Intensive Care Unit with confusion. The patients was intubated because of his Glasgow Coma Score of 6 and respiratory failure. The patient had tachycardia, hypotension, and needed vasopressor medication. While liver function tests were found to be normal, hyperammonemia was thought to be drug-related. The patient's blood valproate level was 1055mg/L (therapeutic normal range: 50-100mg/L). The patient who developed aspiration pneumonia was given meropenem, which was found to be beneficial in valproic acid intoxication. Clinical manifestations of valproic acid poisoning are central nervous system depression, respiratory depression, hypotension, metabolic acidosis, bone marrow failure, brain edema, hypoglycemia, hypernatremia, and hyperammonemia. Treatment of acute valproic acid poisoning usually includes supportive care and fluid therapy, vasopressor support, electrolyte imbalance, and correction of acid-base disorders. Since the initial valproate level was 1055 uq/ml in our case, we applied to hemodialysis as the first treatment. We used levocarnitine especially because it can be useful in hyperammonemia.
Conclusion: As a result, we observed that combined treatment of hemodialysis, levocarnitine and meropenem rapidly decreased the valproic acid level and resulted in a successful recovery.

Abstract

Giriş: Valproik asit (VPA) günümüzde epilepsi, bipolar bozukluk, şizoafektif bozukluk, şizofreni ve migren profilaksisinde kullanılabilen bir ilaçtır. Valproik asit zehirlenmesi merkezi sinir sistemi depresyonu, şok, akut hiperammonemi, beyin ödemi, koma ve ölümle sonuçlanabilir. Bu olguda şiddetli VPA toksisitesi nedeniyle levokarnitin, hemodiyaliz ve meropenem tedavisi uyguladığımız bir hastayı sunmak istedik.
Olgu: 41 yaşında erkek hasta önce acil servise sonrasında Yoğun Bakım Ünitesi’ne bilinç bulanıklığıyla getirildi. Glasgow Koma Skoru 6 ve solunumu yetersiz olduğu için entübe edildi. Hastanın taşikardisi, hipotansiyonu, vasopressor ilaç ihtiyacı vardı. Karaciğer fonksiyon testleri normal bulunurken, hiperammoneminin ilaca bağlı olduğu düşünüldü. Hastanın kan valproat düzeyi 1055mg/L (terapötik normal aralık: 50-100mg/L) bulundu. Aspirasyon Pnömonisi gelişen hastaya valproik asit intoksikasyonunda yararlı olduğu saptanan meropenem verildi. Valproik asit zehirlenmesinin klinik belirtileri, merkezi sinir sistemi depresyonu, solunum depresyonu, hipotansiyon, metabolik asidoz, kemik iliği yetmezliği, beyin ödemi, hipoglisemi, hipernatremi ve hiperamonyemidir. Akut valproik asit zehirlenmesinin tedavisi genellikle destekleyici tedavi ve sıvı tedavisi, vazopresör desteği, elektrolit dengesizliği ve asit-baz bozukluklarının düzeltilmesini içerir. Olgumuzda başlangıç valproat düzeyi 1055 uq/ml olduğu için ilk tedavi olarak hemodiyalize başvurduk. Levokarnitin özellikle hiperammonemide yararlı olabileceğinden kullandık.
Sonuç: Sonuç olarak hemodiyaliz, levokarnitin ve meropenem kombine tedavisinin valproik asit düzeyini hızla düşürdüğü ve başarılı bir şekilde iyileşme sağladığını gözlemledik.
