Cefepime is a fourth-generation cephalosporin widely used for gram-negative sepsis. The authors report two patients in whom nonconvulsive status epilepticus developed while they were on treatment with cefepime for Pseudomonas aeruginosa infection. The status epilepticus resolved completely once the drug was withdrawn. Cefepime therapy can result in status epilepticus, especially if given in higher doses than required.

Neurotoxicity is an unusual complication of cephalosporin therapy. Only few cases of neurotoxicity induced by Cefepime have been described and probably the frequency of Cefepime-induced status epilepticus is underestimated. We report a case of an 82 year-old male, ESRD patient on chronic hemodialysis program affected by pneumonia, who received a treatment with intravenous Cefepime (1 g/day) and developed a seizure 4 days after the starting antibiotic therapy. Cefepime-induced neurotoxicity was suspected and its administration was immediately discontinued. In order to increase Cefepime clearance a hemodialysis session was urgently started and an improvement of his conscious level was observed. On the following day, after a second hemodialysis session his clinical condition and the status of neurotoxicity were completely recovered. The patient was discharged from the hospital in stable clinical condition one week later. At variance with the cases previously reported, the daily dose of Cefepime administrated to our patient was 50% lower and respected drug prescription dosage. Thus, we speculate on the hypothesis that advanced age of our patient and metabolic encephalopathy induced by chronic uremia made him more sensitive to the neurotoxicity induced by the drug. In conclusion, our case suggests that, in very old patients on long-term hemodialysis, it should be considered, to avoid neurotoxicity, to monitor the clinical neurological status, to use Cefepime at lower dosage than that allowed in patients with severe renal impairment (1 g/day) and, when possible, to evaluate Cefepime plasma levels. However, in these patients, other agents of the same class should be considered such as Cefotaxime and Ceftriaxone which are characterized by both an hepatic and renal excretion. In alternative to cephalosporins, antibiotics with the same action spectrum in the absence of neurological toxicity (i.e. Meropenem) should be recommended.

Cefepime, a fourth-generation cephalosporin, with large antibacterial spectrum, is a commonly used antibiotic for the treatment of serious hospital infections. Its security report is considered favourable. Recently, many cases of a severe and reversible cefepime-induced encephalopathy were described. In this paper, we report seven patients with reversible cefepime-induced encephalopathy, with a peculiar EEG pattern, characterized by semiperiodic diffuse triphasic waves. We discuss the EEG abnormalities found and their association with nonconvulsive status epilepticus.

Cefepime is a fourth-generation B-lactam cephalosporin, commonly used in immunosuppressed patients. Neurotoxicity, which present as nonconvulsive status epilepticus (NCSE), has been reported previously especially in adult patients with impaired renal function. We present a case of cefepime induced NCSE after recovering from acute renal failure. A 71-year-old woman was hospitalized for right lower lobe lobectomy after diagnosis of lung cancer. Although she had successful lobectomy, she underwent several post operative complication including operation site bleeding, acute renal failure, acute respiratory distress syndrome, and atypical pneumonia. Her renal failure was prerenal type after massive operation site bleeding, and continuous renal replacement therapy (CRRT) were started for renal replacement treatment. After 5 days of renal replacement therapy, her serum creatinine level was much improved from 2.7 mg/dL to 1.33 mg/dL. Cefepime renal dose were started, when atypical pneumonia became resistant to imipenem and vancomycin. After 5th day of cefepime use, the patient became stupor and developed one episode of brief generalized myoclonic seizure. Her electroencephalograph (EEG) revealed 2-3 Hz generalized sharp and with impression of NCSE, she was started on anti-epileptic treatment. Clinical symptoms improved 3 days after discontinuation of cefepime. She was than diagnosed with cefepime induced non convulsive status epilepticus. Anti-epileptic treatments were than discontinued uneventfully. 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 complication of antibiotic therapy.

Cefepime-induced neurotoxicity, including nonconvulsive status epilepticus, has been reported especially in patients with renal impairment. However, focal nonconvulsive status epilepticus is very rare and cefepime-induced aphasic status epilepticus proven by electroencephalography have never been reported to our knowledge. We present an interesting case of aphasic status epilepticus mimicking acute stroke in a patient treated by cefepime.

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.

A 64-year-old man with fever, appetite loss, and pain in the back of the neck visited our hospital. We diagnosed him as having bacterial meningitis because of pleocytosis of the cerebrospinal fluid, and started treatment with antibiotics. Multiple cerebral infarcts were found on brain MRI. We suspected that the origin of the bacterial meningitis was infective endocarditis, and administered Cefepime and Gentamicin according to the guidelines for treatment of infective endocarditis. Three days later, he became drowsy and had myoclonus and flapping of the extremities. An electroencephalograph showed generalized periodic discharge and a triphasic wave pattern. We thought that the cause of disturbance in consciousness was Cefepime-induced encephalopathy, and stopped administration of Cefepime. A few days later, he became clear, and the myoclonus and flapping disappeared. It was difficult to distinguish between non-convulsive status epilepticus and Cefepime-induced encephalopathy. However, since stopping Cefepime treatment had made the patient clear, we diagnosed his condition as Cefepime-induced encephalopathy, which often occurs in patients with renal or liver dysfunction, or in brain infarction or meningitis, which results in blood-brain barrier disruption. Thus, care should be taken when administering Cefepime to such patients.

Cefepime-induced encephalopathy including nonconvulsive status epilepticus has been known to develop in the patients with renal impairment. However, we report a 74-year-old woman with normal renal function who developed stuporous mental status during cefepime administration. Electroencephalogram (EEG) revealed 2 Hz rhythmic sharp-and-waves continuously, which suggested nonconvulsive status epilepticus (NCSE). After cefepime discontinuation, clinical symptoms recovered gradually and EEG findings showed only background slowing without epileptiform discharges. Cefepime-induced NCSE could be developed even in the patients with normal renal function, when they are elderly. Therefore, clinicians should be aware of the possibility of cefepime-induced NCSE when prescribing cefepime even to the patients with normal renal function.

Neurotoxicity due to cefepime has not been well characterized. We performed a systematic review of the literature and included 5 additional cases from our center. Of the 198 cases found, the mean age was 67 years and 87% of patients had renal dysfunction. The most common clinical features were diminished level of consciousness (80%), disorientation/agitation (47%), and myoclonus (40%). It is worth noting that nonconvulsive status epilepticus was relatively common with 31% of cases, whereas only 11% had convulsive seizures. Single-center estimate of incidence was 1 in 480 courses of cefepime. Cefepime neurotoxicity should be considered in older patients with renal dysfunction and new onset encephalopathy, especially if concurrent myoclonus is present. More work is needed to prospectively assess incidence and outcomes related to cefepime neurotoxicity.

Cefepime is a fourth-generation cephalosporin antibiotic known to have neurotoxic side effects. Recent reports have described patients on cefepime presenting with altered mentation and concurrent triphasic wave discharges on electroencephalogram (EEG). Some have described this clinical presentation as cefepime-induced encephalopathy, while others have termed it as cefepime-induced nonconvulsive status epilepticus (NCSE). We report on 4 patients who developed cefepime-associated altered mentation with triphasic discharges on EEG. A benzodiazepine trial was attempted in 3 of the patients, all of whom had improvement in the frequency of the triphasic discharges, but only 2 of whom demonstrated a concurrent partial and transient improvement in mental status. All 4 patients had normalization of mental status upon discontinuation of cefepime. We provide a literature review of prior cases and propose that these reports, including those labeled as NCSE, are best described as a cefepime-induced encephalopathy with triphasic discharges as opposed to an ictal phenomenon. We contend that aggressive treatment with anti-seizure medications is not warranted and that cefepime discontinuation is the definitive treatment. This case series and review of the literature clarifies a long-standing terminological ambiguity in a unique clinical picture that can be encountered by the neurohospitalist or other providers.
