A 60-year-old woman who for many years had been taking salicylate-containing tablets for headaches, was admitted to hospital, in a somnolent state, because of increasing weakness, tiredness, memory and speech disorders, and tinnitus. Laboratory tests revealed a decompensated metabolic acidosis (pH 7.25), renal insufficiency (creatinine 2.3 mg/dl) and a decreased Quick value (63%). Whole-blood acetylsalicylic acid concentration was markedly elevated to 330 micrograms/ml. After treatment of the acidosis with bicarbonate and forced diuresis she at first regained consciousness, but clouding of consciousness again occurred eight hours later progressing to coma with unequal pupils and seizure potentials in the electroencephalogram. Status epilepticus without motor component was diagnosed, perhaps the result of a dysequilibrium of acid-base balance between blood and cerebrospinal fluid. The signs and symptoms were quickly reversed under treatment with clonazepam.

A 6-year-old boy developed rhabdomyolysis following hyperthermia and status epilepticus with a diagnosis of severe myoclonic epilepsy of infancy. At 2 and 3 years of age, he had similar episodes. Each time he recovered completely in 3-4 weeks with conservative management, in spite of renal insufficiency and marked liver dysfunction. Several cases of recurrent myoglobinuria after intense exercise of generalized tonic-clonic convulsions were reported to have genetic errors of carbohydrate or lipid metabolism of muscle. In our patient, however, the activity of these enzymes was found to be normal. This indicates that status epilepticus may cause recurrent rhabdomyolysis in subjects with normal glycolytic and lipolytic enzyme activity.

Excellent early work on stupor and coma can be found (particularly with regard to anoxia) in the work of Fischgold and Mathis (1959) in France, and Pamela Prior in England (1973a). These workers correlated deepening levels of coma with particular EEG patterns, and the suppression of EEG reactivity. Alpha frequency patterns in coma (alpha coma), spindle-like sleep patterns in coma (spindle coma) and "triphasic waves" are among the wide variety of endocrine disorders discussed in case reports and series leading to identification of particular EEG patterns. EEG correlations with prognosis are most reliable with cardiorespiratory arrest (CRA) with its consequent anoxic-ischemic insult. If etiology is known, EEG can often be a reliable predictor of outcome. EEG usually has little specificity with regards to etiology, but some patterns do favor particular diagnoses: for example, triphasic waves (TWs) are frequently seen with hepatic and renal insufficiency in young adults; spindle coma patterns are believed to indicate dysfunction at the brainstem level (Chatrian, 1990). EEG is most useful in differentiating organic from psychiatric conditions, in excluding nonconvulsive status epilepticus (NCSE), and in providing a rough guide as to the degree of cortical and subcortical dysfunction.

The metabolism of drugs is altered in dialysed patients. We report three clinical cases of neurological toxicity from cefepime in dialysed patient. This molecule can induce in renal insufficiency patients various reversible neurological manifestations like metabolic encephalopathy, myoclonies, or a state of status epilepticus that mimics sometimes a coma in spite of adequate dosing.

The clinical manifestations of antibiotic-induced neurotoxic effects, the underlying mechanisms and management strategies have been reviewed. PubMed and OVID searches (January 1960-June 2010) were conducted using search terms such as antibiotics, side effects, neurotoxicity and encephalopathy which yielded approximately 300 articles. All relevant case reports, case series, letters and retrospective reviews describing neurotoxic effects and those discussing mechanisms of neurotoxicity were included. Antibiotic-induced neurotoxic side effects can have a myriad of neurologic presentations. Patients with prior central nervous system (CNS) disease, renal insufficiency and advanced age may be particularly vulnerable. Treatment consists of discontinuation of the offending agent, use of antiepileptic drugs in the case of seizures or status epilepticus and haemodialysis in certain cases. The risk of CNS toxicity may be reduced via dosage adjustments in high risk populations. Awareness of the potential neurotoxic clinical manifestations of various antibiotics and high degree of vigilance in critically ill patients is essential in identifying a potentially serious, though reversible complications of antibiotic therapy particularly with the advent of newer antimicrobial agents.

Neurotoxicity is a rare side-effect of cefepime. There are previous reports of cefepime neurotoxicity in patients whose dosages were not adjusted for their kidney disease. We report a toxic case of non-convulsive status epilepticus in a patient receiving renally-dosed cefepime. A 70-y-old woman was admitted with febrile neutropenia for which renally-dosed cefepime was started. On day 4 she developed altered mental status with orofacial myokymia. Blood and urine cultures were negative. Cerebrospinal fluid analysis was normal. Head computed tomography and magnetic resonance imaging showed no acute intracranial process. An electroencephalogram showed non-convulsive status epilepticus. Anticonvulsants were started, but she continued to have seizures. At this time, careful review of her medication list with temporal association of symptoms suggested cefepime as a probable cause and the drug was stopped. Within 24 h of discontinuation, her mental status began to improve and returned to baseline in 3 days. Our case illustrates that cefepime toxicity may still occur in patients who are dose-adjusted for renal insufficiency. It also underscores the importance of assessing for additional risk factors like history of stroke and seizures. Because cefepime-induced status epilepticus is completely reversible, prompt recognition and medication discontinuance can prevent further morbidity and mortality.

Dosing cefepime for renal function does not completely prevent neurotoxicity in a kidney transplant patient. Cefepime neurotoxicity has been reported primarily among patients with renal insufficiency who received standard doses of the antibiotic. We report a case of nonconvulsive status epilepticus from dose-adjusted cefepime in a kidney transplant patient. The timing of symptoms along with clinical and electroencephalographic improvement after discontinuation of cefepime was critical to the diagnosis. Whether we should adjust the dose of cefepime differently in a patient with transplanted kidney to prevent neurotoxicity is unknown.
