Abstract includes: “Tumor necrosis factor alpha (TNF- alpha) is a pro-inflammatory cytokine that exerts both homeostatic and pathophysiological roles in the central nervous system. In pathological conditions, microglia release large amounts of TNF-alpha; this de novo production of TNF-alpha is an important component of the so-called neuroinflammatory response that is associated with several neurological disorders. …. As microglial activation and up-regulation of TNF-alpha expression is a common feature of several CNS diseases, as well as chronic opioid exposure and neuropathic pain, modulating TNF-alpha signaling may represent a valuable target for intervention.”

Article includes: “With direct blood extravasation into brain, secondary inflammation is a substantial feature. Drugs which reduce neuroinflammation enhance functional recovery. Lei and colleagues targeted tumor necrosis factor alpha (TNF-alpha), a cytokine that is secreted by the microglia in response to injury and acts as a prime neuroinflammatory mediator causing progressive damage. A single dose of TNF-alpha antibody, CNTO5048, via tail vein 30 min following collagenase-induced ICH in mice showed evidence of reduced neuroinflammation and improved functional deficit in the rotorod task (Lei et al. 2013). Similarly, TNF-alpha antagonist, R-7050 is tested with collagenase-induced ICH mice. Single dose of Intraperitoneal R-7050 given within 2 h of ICH showed reduced edema and blood brain barrier damage with improved neurological deficit assessed from modified 24 point scale (King et al. 2013).”

First paragraph: “Every medical decision should be based on the best available scientific evidence. This goal motivates evidence-based medicine, a movement with undisputable value that improves the rigor of research available for medical decisions. While not the original goal of evidence-based medicine, randomized clinical trials (RCTs) have not simply become the gold standard of confidence but have overshadowed and limited the use of other sources of useful information. As stated by Kaplan et al,1 “over-reliance on RCTs is similar to resting all of health care evidence on a one-legged stool.’ ”

Article includes: “Based on this central effect of TNF-alpha , Tobinick et al. demonstrated dramatic, rapid improvement among 629 consecutive stroke patients following injection of the TNF-alpha blocking drug etan&ercept given perispinally (Batson’s plexus). Statistically significant improvements were seen in a wide range of neurological deficits and symptoms, including motor impairment, spasticity, sensory impairment, cognition, behavioral function, aphasia, and pain. Incredibly, they noted a strong effect even in patients having strokes as long as 10 years previously. They found similar improvements among 12 patients with traumatic brain injury.”

This study was able to look at the effects of etan&ercept (as compared to bupivacaine) on low back pain patients following an injection at 1, 2 and 4 weeks using a visual analog scale and ODI. At the 4-week time point it was shown that TNF-alpha [inhibitor, etan&ercept] provided patients with a statistically significant relief of pain (p<0.005) according to the ODI.”

Article includes: ” Because the intracerebroventricular route is a precarious one, unsuited to regular administration to the same patient, a number of ways to circumvent this problem are being developed to widen the use of these highly successful biological agents to a new patient group. The earliest of these is a novel approach termed the perispinal route (Tobinick et al., 2006, 2010, 2012). Its logic depends on 1) a short period of head-down tilting to gain a gravitational advantage, 2) an awareness of anatomy of Batson’s plexus [a valveless venous system that surrounds the spinal column in continuum with the choroid plexus (Nathoo et al., 2011)], and 3) knowledge of the effect of acute hypertension on choroid plexus permeability [a 30-fold increase in albumin in CSF within 10 min of pharmacologically induced acute local hypertension (Murphy and Johanson, 1985)].”

Abstract includes: “The purpose of this paper is to raise questions about over-reliance on RCTs and to point out an additional perspective for evaluating healthcare evidence, as embodied in the Hill criteria….Excessive reliance on RCTs tends to stifle funding of other types of research, and publication of other forms of evidence. We call upon our research and clinical colleagues to consider additional methods of evaluating data, such as the Hill criteria. Over-reliance on RCTs is similar to resting all of health care evidence on a one-legged stool.”

Article includes: “In particular, the recent trial with etan&ercept [citing to Tobinick, E.L. and H. Gross, Rapid cognitive improvement in Alzheimer’s disease following perispinal etan&ercept administration. J Neuroinflammation, 2008. 5: p. 2] has provided much insight into pathogenesis and possible future treatment options. Not only does this anti-inflammatory agent improve results of memory testing (MMSE) over a 6-month period, it also has been shown to improve verbal fluency and apraxia in patients. Etan&ercept is a specific antagonist of TNF-alpha. Studies now suggest that TNF-alpha may also regulate synaptic transmission and mediate beta-amyloid and beta-amyloid oligomer disruption of memory mechanisms. The rapid onset of effect with etan&ercept suggests the synaptic effect is the most important.”

Discussing the use of TPA as a treatment for acute stroke, the article discusses the resistance of the neurological community: “I am writing to convey my impressions of the lack of enthusiasm for this therapy [TPA for acute stroke] exhibited by neurologists at places where I have spoken. Rather than embrace, or at least acknowledge, this as the first step in the treatment of neurology’s most common serious and debilitating disease (Alzheimer disease excepted), it often has been met with skepticism, criticism and denial, with discussions centered around why t-PA cannot or should not be used, rather than how it could be used. Such negativism is now evident in the neurological literature in an article with the unambiguous title: “Tissue-type Plasminogen Activator Should Not Be Used in Acute Ischemic Stroke” ” Horowitz 1998 ***Of significant historical relevance

Quote: “Evidence based medicine is the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research. By individual clinical expertise we mean the proficiency and judgment that individual clinicians acquire through clinical experience and clinical practice. Increased expertise is reflected in many ways, but especially in more effective and efficient diagnosis and in the more thoughtful identification and compassionate use of individual patients’ predicaments, rights, and preferences in making clinical decisions about their care. By best available external clinical evidence we mean clinically relevant research, often from the basic sciences of medicine, but especially from patient centered clinical research into the accuracy and precision of diagnostic tests (including the clinical examination), the power of prognostic markers, and the efficacy and safety of therapeutic, rehabilitative, and preventive regimens. External clinical evidence both invalidates previously accepted diagnostic tests and treatments and replaces them with new ones that are more powerful, more accurate, more efficacious, and safer.”
