Patients with epilepsy may suffer from renal or hepatic diseases that interfere with their antiepileptic drug (AED) treatment. Furthermore, such diseases may themselves cause seizures. Reduced renal function and hypoalbuminemia lead to accumulation of renally excreted AEDs, such as gabapentin, vigabatrin, topiramate, levetiracetam, and phenytoin. Valproate, lamotrigine, and benzodiazepines are less affected. Low protein-bound AEDs are extensively removed by hemodialysis and supplemental doses are required for dialysis patients. Uremia and related conditions, including intracranial hemorrhage, glucose and electrolyte imbalances, and concomitant drug use, can cause seizures, as can dialysis encephalopathy, primary cerebral lymphoma, fungal infections, and immunosuppressant toxicity in renal transplant recipients. Hepatic dysfunction reduces enzymatic metabolism of AEDs and causes hypoalbuminemia. Gabapentin, topiramate, and levetiracetam. are preferred in these conditions, whereas conversely valproate and felbamate are potentially hepatotoxic and should be avoided. Seizures related to hepatic encephalopathy are controlled by oral lactulose or neomycin. Porphyria sufferers may benefit from gabapentin, oxcarbazepine, or levetiracetam. Seizures in Wilson's disease may derive from D-penicillamine-induced pyridoxine deficiency. Effective treatment of seizures in renal and hepatic diseases requires attention to changes in AED pharmacokinetics and adequate care of the underlying illnesses. Monitoring of free drug concentrations is a valuable aid to therapy.
