Treatment of refractory and superrefractory status epilepticus with topiramate: A cohort study of 106 patients and a review of the literature

Anne FechnerAdam Strzelczyk


Novel treatments are needed to control treatment-resistant status epilepticus (SE). We present a summary of clinical cases where oral topiramate (TPM) was used in refractory SE (RSE) and superrefractory SE (SRSE). A review of medical records was carried out to detect TPM administration in SE patients treated in Frankfurt and Marburg between 2011 and 2016. The primary outcome question concerned SE resolution after TPM initiation. In total, TPM was used in 106 of 854 patients having a mean age of 67.4 ± 18.1 years, 61 of whom were female (57.5%). The median latency from SE onset to TPM initiation was 8.5 days. Patients with SE had previously failed a median of five other antiepileptic drugs. The median initial TPM dose was 100 mg/d, which was uptitrated to a median maintenance dose of 400 mg/d. Treatment with TPM was continued for a median time of 12 days. TPM was the last drug provided to 42 of 106 (39.6%) patients, with a resultant response attributed to TPM observed in 29 of 106 (27.4%) patients. A response was attributed to TPM in 21 (31.8%) of 66 RSE cases and eight (20%) of 40 SRSE cases. Treatment-emergent adverse events were attributed to TPM usage in two patients, one each with pancreatitis and hyperchloremic acidosis, a...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
