International Veterinary Epilepsy Task Force consensus proposal: Medical treatment of canine epilepsy in Europe

In Europe, the number of antiepileptic drugs (AEDs) licensed for dogs has grown considerably over the last years. Nevertheless, the same questions remain, which include, 1) when to start treatment, 2) which drug is best used initially, 3) which adjunctive AED can be advised if treatment with the initial drug is unsatisfactory, and 4) when treatment changes should be considered. In this consensus proposal, an overview is given on the aim of AED treatment, when to start long-term treatment in canine epilepsy and which veterinary AEDs are currently in use for dogs. The consensus proposal for drug treatment protocols, 1) is based on current published evidence-based literature, 2) considers the current legal framework of the cascade regulation for the prescription of veterinary drugs in Europe, and 3) reflects the authors’ experience. With this paper it is aimed to provide a consensus for the management of canine idiopathic epilepsy. Furthermore, for the management of structural epilepsy AEDs are inevitable in addition to treating the underlying cause, if possible

Effects of different types of statins on lipid profile: a perspective on Asians

Context: The present review aimed at reviewing the effects of different statins on lipid profile, particularly in Asians. Evidence Acquisition: PubMed searches were conducted using the keywords ‘statin, effect, and lipid profile’ from database inception through March 2016. In this review, 718 articles were retrieved from the primary search. After reviewing the titles, abstracts, and full texts, we found that 59 studies met our inclusion criteria. These also included subsequent reference searches of retrieved articles. Results: CURVES study compared the effect on lipid profile between atorvastatin and other statins. This study demonstrated that low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), and triglycerides (TG) were reduced more with atorvastatin compared to simvastatin, pravastatin, lovastatin, and fluvastatin. However, simvastatin provided a greater elevation of high-density lipoprotein cholesterol (HDL-C) compared to atorvastatin. The STELLAR trial was based on dose-to-dose comparisons between atorvastatin and rosuvastatin efficacy in reducing LDL-C. Te present study also revealed that as the doses of rosuvastatin, simvastatin, and pravastatin increased, HDL-C also increased, with rosuvastatin having the greatest effect. However, HDL-C levels decreased as the dose of atorvastatin increased. The DISCOVERY study involving the Asian population revealed that the percentage of patients achieving the European goals for LDL-C and TC at 12 weeks was higher in rosuvastatin group compared to atorvastatin group. Conclusions: The effects of statins on lipid profile are dose dependent. Most studies showed that rosuvastatin has the best effect on lipid profile. Prescribing lower doses of statins in Asians seems necessary

Gabapentin suppresses cortical spreading depression susceptibility

Cortical spreading depression (CSD) is an intense depolarization wave implicated in the pathophysiology of brain injury states and migraine aura. As Cav2.1 channels modulate CSD susceptibility, we tested gabapentin, which inhibits Cav2.1 through high-affinity binding to its α2δ subunit, on CSD susceptibility in anesthetized rats. Gabapentin, 100 or 200 mg/kg, elevated the electrical threshold for CSD and diminished recurrent CSDs evoked by topical KCl, when administered 1 hour before testing. With its favorable safety and tolerability profile, gabapentin may have a role in suppression of injury depolarizations in stroke, intracranial hemorrhage, and traumatic brain injury
