High levels of cerebrospinal fluid chemokines point to the presence of neuroinflammation in peripheral neuropathic pain: a cross-sectional study of 2 cohorts of patients compared with healthy controls

Abstract Animal models suggest that chemokines are important mediators in the pathophysiology of neuropathic pain. Indeed, these substances have been called “gliotransmitters,” a term that illustrates the close interplay between glial cells and neurons in the context of neuroinflammation and pain. However, evidence in humans is scarce. The aim of the study was to determine a comprehensive cerebrospinal fluid (CSF) inflammatory profile of patients with neuropathic pain. Our hypothesis was that we would thereby find indications of a postulated on-going process of central neuroinflammation. Samples of CSF were collected from 2 cohorts of patients with neuropathic pain (n = 11 and n = 16, respectively) and healthy control subjects (n = 11). The samples were analyzed with a multiplex proximity extension assay in which 92 inflammation-related proteins were measured simultaneously (Proseek Multiplex Inflammation I; Olink Bioscience, Uppsala, Sweden). Univariate testing with control of false discovery rate, as well as orthogonal partial least squares discriminant analysis, were used for statistical analyses. Levels of chemokines CXCL6, CXCL10, CCL8, CCL11, CCL23 in CSF, as well as protein LAPTGF-beta-1, were significantly higher in both neuropathic pain cohorts compared with healthy controls, pointing to neuroinflammation in patients. These 6 proteins were also major results in a recent similar study in patients with fibromyalgia. The findings need to be confirmed in la...

Conclusions: Monitoring the affective dimension of pain should be included in an integrated approach to pain, and Hatha yoga may be beneficial in the pain management of FM participants. PMID: 31370034 [PubMed - in process]

Over the last 12 months New Zealanders have entered into the debate about cannabis and cannabinoids for medical use. In the coming year we’ll hear even more about cannabis as we consider legalising cannabis for recreational use. There is so much rhetoric around the issue, and so much misinformation I thought it high time (see what I did there?!) to write about where I see the research is at for cannabis and cannabinoids for persistent pain. For the purposes of this blog, I’m going to use the following definitions: Cannabis = the plant; cannabis-based medication = registered extracts (either synthetic or from...

Conclusion: The results of our study may suggest the presence of FM as a clinical sign of a more severe migraine. However, the long-term prospective studies including these group of patients are needed to understand the prognostic impact and importance of the comorbid FM in migraine.

I was looking back over the last 8 years since the first Wheat Belly book was released. It’s been 8 years of astounding, truly breathtaking stories of success over weight issues, health, and physical transformations that skeptics even today claim are impossible. It’s been a virtual avalanche of wonderful stories. Although I’ve seen all of them, often more than once, I could not help but be overcome with satisfaction and pride for the many, many spectacular photos and stories people have shared. So I thought it would be fun to re-post a small sample of some of these stories dating back from the start of th...

Conclusion: These findings support the hypothesis that in FM a deteriorated function of cortical inhibition, indexed by a higher SICI parameter, a lower function of the DPMS, together with a higher level of BDNF indicate that FM has different pathological substrates from depression. They suggest that an up-regulation phenomenon of intracortical inhibitory networks associated with a disruption of the DPMS function occurs in FM. Introduction Major depressive disorder (MDD) and fibromyalgia (FM) present overlapped symptoms. Although the connection between these two disorders has not been elucidated yet, the disruption...

This study had a large sample size and obtained positive findings in both patients’ subjective ratings and in inflammatory marker levels. It demonstrates the benefits of adding Tai Chi to an antidepressant regimen but does not examine the specific effect of Tai Chi on depression.Field et al. (16) investigated the effects of combined Tai Chi/yoga in 92 prenatally depressed pregnant women. They found that women practicing Tai Chi/yoga (20 min per week for 12 weeks) had lower depression, anxiety, and sleep disturbance scores compared to a waitlist control group (Table 1). This study had a large sample size and provided ...

CONCLUSIONS: At the moment, ozone therapy seems a treatment that, also because without any side effect, is possible to be proposed to patients with fibromyalgia that are not obtaining adequate results from other available treatments and it can be considered as complementary/integrative medicine.

Authors: Silva AR, Bernardo A, Costa J, Cardoso A, Santos P, Mesquita MF, Vaz Patto J, Moreira P, Silva ML, Padrão P Abstract Fibromyalgia (FM) is a chronic non-degenerative disease, whose nutritional therapy seems controversial. This systematic review aimed to synthesize the knowledge about the effect of dietary interventions on patient reported outcomes (PRO) and inflammation in patients with FM. Six electronic databases - PubMed, BioMed Central, Cochrane library, EMBASE, LILACS and ISI - were searched for clinical trials, in which a dietary intervention in patients with FM diagnosed was conducted. Quality...

Fibromyalgia (FM) is characterized by chronic widespread pain whose pathophysiological mechanism is related to central and peripheral nervous system dysfunction. Neuropathy of small nerve fibers has been implicated due to related pain descriptors, psychophysical pain, and neurophysiological testing, as well as skin biopsy studies. Nevertheless, this alteration alone has not been previously associated to the dysfunction in the descending pain modulatory system (DPMS) that is observed in FM. We hypothesize that they associated, thus, we conducted a cross-sectional exploratory study. To explore small fiber dysfunction using ...
