Treatment of epileptic seizures in patients with hepatic porphyrias is a challenging problem due to enzymatic induction activity of phenobarbital (PB), phenytoin (PHT), carbamazepine (CBZ), and clonazepam (CZP). We present the case of a patient with partial seizures treated with PHT and showing
We report the case of a 50-year-old male patient with idiopathic generalised epilepsy and porphyria cutanea tarda. Valproic acid and phenobarbital monotherapy controlled seizures but exacerbated porphyric symptomatology, while clobazam, clonazepam and lamotrigine monotherapy were well tolerated as
Porphyria cutanea tarda is a disorder of heme biosynthesis resulting from a defect or deficiency in the enzyme uroporphyrinogen decarboxylase. Heme precursors accumulate in the blood, urine, stool, and skin, where exposure to sunlight results in the clinical manifestations. Porphyria cutanea tarda
The porphyrias comprise a group of disorders of the haem biosynthesis pathway that can present with acute neurovisceral symptoms, skin lesions or both. Acute porphyrias present with severe abdominal pain, confusion and seizures which may be life-threatening. Specific treatment with haem preparations
The porphyrias are a group of rare metabolic disorders, inherited or acquired, along the heme biosynthetic pathway, which could manifest with neurovisceral and/or cutaneous symptoms, depending on the defective enzyme. Neurovisceral porphyrias are characterized by acute attacks, in which excessive
OBJECTIVE
Despite the development of new antiepileptic agents (AEDs), the therapy of epilepsies along with hepatic porphyrias remains difficult. Most AEDs such as carbamazepine (CBZ), phenytoin (PHT), valproate (VPA), and lamotrigine (LTG) may precipitate clinically latent porphyria by inducing
Striopallidodentate calcinosis (Fahr's disease) is characterized clinically by seizures, rigidity, and dementia and pathologically by mineral deposition in the basal ganglia, dentate nucleus, and cerebral cortex. Disorders of iron and calcium-phosphate metabolism are thought to play a role in its
