Lack of neuroprotective effects of simvastatin and minocycline in a model of cervical spinal cord injury.

Minocycline, a commonly prescribed tetracycline antibiotic, has shown promise as a potential therapeutic agent in animal models of numerous neurologic disorders such as amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease, Huntington's disease, stroke, and spinal cord injury (SCI). Simvastatin is one of many hydroxymethylglutaryl-coenzyme-A reductase inhibitors prescribed to lower cholesterol. These drugs are also known to reduce inflammation and oxidative stress, improve endothelial function, and modulate the immune system in stroke, traumatic brain injury, and SCI.

Cerebrospinal fluid inflammatory cytokines and biomarkers of injury severity in acute human spinal cord injury.

There is an urgent need for both the scientific development and clinical validation of novel therapies for acute spinal cord injury (SCI). The scientific development of novel therapies would be facilitated by a better understanding of the acute pathophysiology of human SCI. Clinical validation of such therapies would be facilitated by the availability of biomarkers with which to stratify injury severity and predict neurological recovery.

Lack of robust neurologic benefits with simvastatin or atorvastatin treatment after acute thoracic spinal cord contusion injury.

Although much progress has been made in the clinical care of patients with acute spinal cord injuries, there are no reliably effective treatments, which minimize secondary damage and improve neurologic outcome. The time and expense needed to establish de novo pharmacologic or biologic therapies for acute SCI has encouraged the development of neuroprotective treatments based on drugs that are already in clinical use and, therefore, have the advantage of a well-characterized safety and pharmacokinetic profile in humans. Statins are the most commonly prescribed class of lipid-lowering drugs, and recently, it has been recognized that statins also have powerful immunomodulatory and anti-inflammatory effects.

Delayed treatment of spinal cord injury with erythropoietin or darbepoetin--a lack of neuroprotective efficacy in a contusion model of cord injury.

A number of drugs commonly used for a variety of clinical indications have been found recently to have substantial neuroprotective properties, raising the potential for rapid translation into human clinical trials of spinal cord injury (SCI). In this study we compared the neuroprotective efficacy of erythropoietin and a derivative of it, darbepoetin, in an acute model of thoracic SCI. Sprague-Dawley rats were randomized to receive erythropoietin (5000 IU/kg), darbepoetin (10 mug/kg), or saline, as a single intravenous injection 1 h after a thoracic contusion SCI.
