MedicalResearch.com: What is the background for this study? How does EXPAREL® differ from other pain medication for dental work or other short-term procedures?

Response: This study analyzed the use of opioids and non-opioid options for postsurgical pain following third molar extraction (wisdom teeth removal). Our research team reviewed data from 600 patients who underwent third molar extraction, with 300 patients having received non-opioid option EXPAREL (bupivacaine liposome injectable suspension) and 300 patients that did not receive an infiltration of EXPAREL. The study aimed to show that reducing opioid prescriptions following this procedure may decrease opioid-related adverse events and the risk of opioid dependence.

MedicalResearch.com: What is the background for this study?

Response: Chronic pain is one of the common side effects of cancer treatments and it has been linked to low life quality, lower adherence to treatment, higher medical cost. As the population of cancer survivors grows rapidly, chronic pain will be a major public health issue in this population. We know from previous studies that chronic pain is common in certain cancers such as breast cancer. However, little was known about the epidemiology of chronic pain in the cancer survivors until our study.

MedicalResearch.com: What is the background for this study?

Response: Previous research has reported empathy deficits in patients with major depressive disorder. However, a high percentage of patients taking part in these studies were taking antidepressants, which are known to influence emotion processing. In our study, we wanted to overcome this important limitation. We were interested in whether the previously reported empathic deficits were attributable to the acute state of depression, or to the antidepressant treatment.

To this end, we performed a longitudinal neuroimaging study, in which we measured brain activity and self-reported empathy in response to short video clips showing people in pain. We measured acutely depressed patients twice. First, before they started their treatment, second, after three months of treatment with a state-of-the-art antidepressant (selective serotonin reuptake inhibitors).

MedicalResearch.com: What is the background for this study?

Response: The opioid epidemic is exacting a significant burden on families, communities and health systems across the U.S. Prescription and illicit opioids are responsible for the highest drug overdose mortality rates ever recorded. We know from previous studies that some surgical and medical patients who fill opioid prescriptions immediately after leaving the hospital go on to have chronic opioid use. Until our study, however, little was known about how and if those patients were being introduced to the opioids while in the hospital.

My colleagues and I reviewed the electronic health records of 191,249 hospital admissions of patients who had not been prescribed opioids in the prior year and were admitted to a community or academic hospital in Pennsylvania between 2010 and 2014. Opioids were prescribed in 48% of the admissions, with those patients being given opioids for a little more than two-thirds of their hospital stay, on average.

Duke University 

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: This was a multicenter study conducted in 13 clinical sites in the United States enrolling patients undergoing elective Cesarean-section and receiving spinal anesthesia. 186 patients were enrolled and randomized to receive EXPAREL, a long-acting, non-opioid option to manage postsurgical pain, administered via transversus abdominis plane (TAP) field block, mixed with plain bupivacaine or TAP block with plain bupivacaine alone. A TAP block numbs the nerves that supply the abdominal wall. We presented the data at the 51st Annual Meeting of the Society of Obstetric Anesthesia and Perinatology (SOAP) in Phoenix, AZ.

We aimed to collect clinical evidence that a multimodal postsurgical pain regimen using a TAP block with EXPAREL (bupivacaine liposome injectable suspension) together with regularly scheduled acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) could reduce opioid consumption more so than a standard multimodal pain control approach that combines TAP block with standard bupivacaine, regularly scheduled acetaminophen, and NSAIDs.

MedicalResearch.com: What is the background for this study?  

Response: The ultimate background for this study does come from the larger context of the opioid epidemic that is seen worldwide but particularly in North America. Orthopaedic surgeons should take responsibility as being among the top prescribers of opioids.

The more specific background that led to this specific study was the observation that several colleagues would insist that a drug like hydromorphone was so dangerous that they would not prescribe it but seemed okay prescribing large amounts of oxycodone.  It seemed like an urban myth that the type of opioid was what made it dangerous, so that led us to do the study to see if there was evidence for that.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Some individuals prescribed opioid analgesic medications for pain develop opioid use disorder. So, much research has been conducted to develop strategies to identify patients who can be safely prescribed opioid analgesics. However, this research has not been critically reviewed through rigorous quality assessment.

This study therefore sought to identify signs, symptoms & screening tools to identify patients with pain who can be safely prescribed opioids  Continue reading

Is There a Risk of Bleeding With Ibuprofen After Tonsillectomy ?

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Pediatric tonsillectomy is a commonly performed procedure, representing the second most common ambulatory surgery performed on children in the United States, with over half a million children undergoing the surgery annually.  A major concern for surgeons, patients, and their families is the issue of postoperative pain control as pain can last up to 10-14 days after surgery, be quite severe, and result in readmission to the hospital or ED visits for medications and dehydration.

In young children and children with sleep apnea we cannot safely administer narcotic pain medications at home.  This leaves limited options for pain control, including acetaminophen and ibuprofen.  However, there are concerns that ibuprofen could potentially increase bleeding risk after surgery because of its effects on platelet function in the blood.  At baseline, the risk of postoperative hemorrhage within the first two weeks after tonsillectomy is around 4.5%, with about 1-1.5% of children requiring a return to the operating room to control severe bleeding.  Our study set out to show that the risk of severe postoperative bleeding when ibuprofen is given for 9 days after tonsillectomy was not increased compared with the bleeding risk when acetaminophen was administered instead.

Our study could not conclude that the risk of bleeding is no different when ibuprofen is used, and was suggestive that the bleeding risk may actually be higher. Continue reading

Hip Replacement Surgery Pain: No Benefit To IV Acetaminophen over Pills

MedicalResearch.com: What is the background for this study?

Response: Recent mortality trends in the U.S. associated with opioid use disorders have brought to the forefront of national debate the desirability of minimizing the use of potentially addictive pain management therapies.  Pain management after hip replacement surgery is an important part of patient care, and  opioids are frequently given as a major part of postoperative pain management.

At the same time, multimodal analgesia, the administration of anesthetic agents and medications agents targeting multiple pain pathways, has seen increased popularity in pain management after hip replacement surgery.  At Hospital for Special Surgery (HSS), the multimodal protocol entails the use of several different anesthetic agents and medications both during and after surgery to control pain, minimize the use of opioids and reduce side effects.

The use of non-opioid analgesics such as acetaminophen allows for a reduction in opioid administration after surgery [1]. Acetaminophen, commonly known as Tylenol, has traditionally been administered orally, but more recently an intravenous (IV) preparation has become available.  IV acetaminophen after major orthopedic surgery was shown to provide effective analgesia and reduce morphine administration by 33%, compared to placebo [2].

Unless a patient is unable to take acetaminophen, it is commonly used as part of the multimodal protocol due to its efficacy and minimal contraindications. Although intravenous (IV) acetaminophen presents pharmacokinetic benefits, such as increasing both serum blood and cerebrospinal fluid levels more rapidly, there is limited analysis of its potential clinical advantages compared to oral acetaminophen.  We hypothesized that there could be a reduction in pain with activity, opioid usage, or opioid- related side effects among patients receiving IV acetaminophen compared to oral acetaminophen following hip replacement surgery  Continue reading

Most Counties See Opioid Prescription Rates Falling

CDC

MedicalResearch.com: What is the background for this study?

Response: This study examined opioid prescribing at the national and county-level in 2015 and 2017.

During 2015 to 2017, the amount of opioids prescribed decreased 20.1% in the United States. The amount of opioids prescribed per person varies substantially at the county-level. The average amount of opioids prescribed in the highest quartile of counties was nearly 6 times the amount in the lowest quartile. Reductions in opioid prescribing could be related to policies and strategies aimed at reducing inappropriate prescribing, increased awareness of the risks associated with opioids, and release of the CDC Guideline for Prescribing Opioids for Chronic Pain.

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Even though Migraine with aura was associated with an increased risk of ischemic stroke in the Atherosclerosis Risk in Communities study (ARIC), our post-hoc showed unexpected results that onset of such migraines before age 50 years is not associated with such risk. Instead, later onset of migraine with aura after age of 50 was linked with a higher risk of ischemic stroke.

Total of 447 migraineurs with aura (MA) and 1128 migraineurs without aura (MO) among 11,592 participants were included in the analysis. There was a two-fold increased risk of ischemic stroke when the age of migraineurs with aura onset was 50 years or older as compared with no headache participants, MO was not associated with increased stroke risk regardless of age of onset.  Continue reading

Lumbar Spinal Stenosis: Non-Surgical Options Compared

MedicalResearch.com: What is the background for this study?

Response: Lumbar spinal stenosis (LSS) is one of the fastest growing problems in the country due to its aging population. One third of Medicare users have the condition, and it is the number one reason for spine surgery in this population. Existing research evaluates the benefits of nonsurgical treatment options compared to surgery, but there was no existing research that compared the available nonsurgical options to each other to determine the best course of treatment for each patient.

We studied three nonsurgical treatments for LSS: medical management with medications and/or epidural injections, individualized care with a physical therapist or chiropractor, and group exercise. We assessed each of these treatment methods with a questionnaire, a walking distance test, and a physical activity monitor.

Pilates Enabled Patients with Musculo-Skeletal Symptoms to Function Better

MedicalResearch.com Interview with:
Ms Lynne Gaskell MSc
University of Salford
Manchester UK

MedicalResearch.com: What is the background for this study?

Response: Musculoskeletal Pain as a result of common problems affecting the back, neck, shoulder, knee and multi-site pain is an increasing cause of reduced function and quality of life, and ever increasing demands on healthcare, Prognosis is often poor with many people reporting persistent symptoms after consulting their primary care practitioner. The likelihood of persistent and recurrent clinical symptoms may accentuate the physical, psychological, and social impacts of musculoskeletal pain particularly with the middle aged and elderly populations. Pilates is an exercise approach that has become increasingly popular in recent years and includes over fifty different exercises to improve flexibility, balance, core strength, core stability. It can therefore can be individualised for people with different needs, preferences, musculoskeletal conditions, ages and abilities. Aligning exercise to patient’s functional needs has been linked to long-term exercise adherence. Many physiotherapists such as sydney physio solutions have started to specialise in this as a form of treatment, click here for more info on pilates and the many benefits they can have on your physical health.

This study investigated the personal experiences and perceptions of the impact of Pilates on the day-to-day lives of adults with a myriad of chronic MSK conditions following a 12 week Pilates Exercise Programme.The results were organised into five main themes: 1. Physical Improvements strength, core stability, flexibility and balance. 2. Pilates Promotes an Active Lifestyle and improved performance at work and / or hobbies. 3. Psychosocial benefits and improved confidence, 4. Increased Autonomy in Managing their own Musculoskeletal Condition and 5. Motivation to continue with exercise.

NSAID Eyedrop + Eye Patch Better at Reducing Pain After Intravitreal Injection

MedicalResearch.com Interview with:

Ronald Gentile, MD Professor of Ophthalmology Icahn School of Medicine at Mount Sinai New York

Dr. Gentile

Ronald Gentile, MD
Professor of Ophthalmology
Icahn School of Medicine at Mount Sinai
New York

MedicalResearch.com: What is the background for this study?

Response: Intravitreal injections have revolutionized the treatment of some of the most common retinal diseases that cause blindness. These diseases include wet age related macular degeneration and diabetic retinopathy. Intravitreal injections are the most common eye procedure in the world. Pain after an intravitreal injection negatively impacts the patient’s experience. We set out a to find a way to improve the patient’s experience by improving the pain they feel after the intravitreal injection.

MedicalResearch.com: What are the main findings? 

Response: The main finding was that the NSAID we used, Nepafanac 0.3% suspension, and pressure patching resulted in lower pain scores when compared to the tear drop placebo at both 6 and 24 hours after the intravitreal injection. The NSAID had a greater effect on lowering the pain score and was found statistically significance. Even though the eyepatch was associated with lower pain scores than placebo, the difference did not reach statistical significance. 

MedicalResearch.com: What should readers take away from your report?

Response: Readers should understand that patients not only have a fear going blind, they also fear the pain of the treatment. Physicians should place more emphasis on the patients experience and try to decrease or eliminate any pain a patient may have from the intravitreal injections. It would be expected that this should help patient compliance, especially for those patient who need regular intravitreal injections. 

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: Future research should focus on the patients experience and find ways to eliminate any pain a patient may have before, during, and after the intravitreal injections. 

MedicalResearch.com: Is there anything else you would like to add?

Response: Yes. Patient satisfaction and the patient experience is something that all ophthalmologists and all doctors need to put on the top of their priority list. Physicians have the greatest ability and insight into this. Having the greatest medicines in the world cant help if a patients fear of pain prevents them from being compliant.

I have no disclosures.

Program Can Help Parents Manage Kids’ Pain from Vaccines

MedicalResearch.com Interview with:

Dr. Anna Taddio BScPhm PhD Professor at the Leslie Dan Faculty of Pharmacy University of Toronto and Senior Associate Scientis The Hospital for Sick Children 

Dr. Taddio

Dr. Anna Taddio BScPhm PhD
Professor at the Leslie Dan Faculty of Pharmacy

The Hospital for Sick Children 

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: In our prior research, parents have reported they are not educated about how to soothe their infants during painful procedures like vaccinations and that they want to know how they can help. Parents also reported that concerns about their infant’s pain affects their decision-making around vaccination. We therefore set out to target parents for education about how to soothe their infants.

We picked the hospital setting because almost all parents are in the hospital for some period of time following the birth of an infant and already routinely receive education about healthy baby topics. Providing information about pain management was easy to add. We found that about 1 out of 10 parents that were given this information acted on it. 

MedicalResearch.com: What should readers take away from your report?

Response: No parent wants to see their child in pain and a parents’ desire to reduce pain is supported when we provide them with evidence-based strategies to use. These strategies are easy to use, and not only decrease unnecessary infant suffering, they also help parents. Parents are less anxious about their children getting vaccinations. Attending to infant distress is also important for healthy infant development. Targeting parents at the time of birth also ensures that parents will use and advocate for better pain care for their children across different  medical settings and throughout the lifespan.

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: We need to find ways to reach more parents so that they can use this information to help their children. We also need to follow parents over time and teach them about the strategies that are helpful for children of different ages. Finally, we need to study how better pain management practices impacts on vaccination rates.

Fibromyalgia: Scan Reveals Increased Brain Activation in Pain, Emotion and Affect Areas

MedicalResearch.com Interview with:
Daniel S. Albrecht, Ph.D.

Research Fellow, Department of Radiology
Harvard Medical School

MedicalResearch.com: What is the background for this study? Can you briefly describe what is meant by fibromyalgia?

Response: Fibromyalgia (FM) is a poorly understood chronic condition characterized by widespread musculoskeletal pain, fatigue, unrefreshing sleep, memory deficits and attention difficulties, among other symptoms. FM affects an estimated 4 million adults in the U.S., but despite this prevalence, effective therapies for treating FM are lacking.

Credit: Marco Loggia, PhD, Martinos Center for Biomedical Imaging, Massachusetts General Hospital

Part of the reason for the paucity of effective therapeutics is insufficient knowledge of the underlying mechanisms contributing to FM. Previous work from co-senior author of the current manuscript, Eva Kosek, MD, PhD, and collaborators at the Karolinska Institute in Sweden found elevated inflammatory molecules in the cerebrospinal fluid of FM patients, which could be reflective of brain neuroinflammation in these patients. However, no study had directly assessed the presence of neuroinflammation in the brain of FM patients.

Co-senior author of the study, Marco Loggia, PhD, and collaborators showed in a 2015 Brain publication that individuals with chronic low back pain (cLBP) exhibit evidence of brain neuroinflammation, specifically activation of glial cells. Our team utilized simultaneous MR/PET imaging to image brain levels of the 18 kDa translocator protein (TSPO), which is widely used as a marker of glial activation due to vast upregulation of TSPO in glial cells, e.g. microglia and astrocytes, in preclinical models of inflammation and neurological disease. Dr. Loggia sought to extend these finding in cLBP to FM, hypothesizing that activation of glial cells may also be associated with FM pathology. To this end, we used the same TSPO PET tracer to image 20 FM patients and 16 healthy controls.

During a conference where I was presenting preliminary results of the fibromyalgia study, Dr. Loggia met with Dr. Kosek and discovered that, across the Atlantic, her group was performing a very similar study, imaging 11 FM patients and 11 controls with the same TSPO PET compound. They decided to form a collaboration, and logistic talks began to determine the best strategy to combine and analyze the separate datasets. In addition to PET imaging with the TSPO tracer, which is suggested to reflect activated microglia and astrocytes, Dr. Kosek’s group also collected PET scans using a tracer thought to bind specifically to astrocytes rather than microglia. This tracer was used in order to discern the relative contributions of microglia and astrocytes to any observed differences in TSPO PET signal.

Dr. Markman

John Douglas Markman, M.D.
Director, Translational Pain Research Program

Professor
University of Rochester School of Medicine and Dentistry 

MedicalResearch.com: What is the background for this study?

Response: Peripheral nerve injury after trauma and surgery is a leading cause of chronic pain and disability. These pain syndromes are often considered to have an underlying neuropathic mechanism because there is altered sensory processing (e.g., numbness, allodynia) at the site of trauma or surgical incision that localizes to the anatomic distribution of a peripheral nerve. A previous eight-week randomized clinical trial demonstrated efficacy for pregabalin in patients with chronic post-traumatic or -surgical pain.(10) The longer duration of treatment of this study was designed to meet the regulatory standard for a chronic pain indication in the US, 12 weeks of treatment at maintenance or fixed dosing.

MedicalResearch.com: What is the background for this study?

 

Response: For the past several years we have been using observational research designs as a means to overcome some of the logistical and legal barriers for conducting patient outcomes medical cannabis research. In partnership with the software developers of the Releaf App which currently is the largest repository of user-entered information on the consumption and effects of cannabis use in the United States, we have been able to measure how patients choose to consume cannabis and the effects of those choices in real-time.  Since its release in 2016, the commercially developed Releaf App has been the only publicly available, incentive-free patient educational software program designed for recording how individual cannabis usage sessions correspond to immediate changes in symptom intensity levels and experienced side effects.

Dr. Jonas

Wayne B. Jonas, MD
Clinical Professor of Family Medicine
Uniformed Services University and at
Georgetown University School of Medicine

MedicalResearch.com: What is the background for this study?

Response: The search for non-drug approaches to chronic pain is a major recommendation in many recent guidelines for both pain management and reduction in the use of opioids. Surgical and invasive procedures are non-drug approaches often used for pain conditions like back pain and arthritis, so good evidence is needed to determine the safety and efficacy of these procedures. Properly done randomized, placebo controlled trials are the best way (the gold standard) to get that evidence, so we did a thorough evaluation of such research, using standard systematic review and meta-analysis methods.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Cosmetic and functional rhinoplasty (nasal surgery) is the most common procedure we perform and traditionally post operative pain medication includes opioids.

In light of the recent opioid epidemic, we wished to investigate if patients pain was being treated over-treated by surgeons.

Of 173 Rhinoplasties that we performed, the majority of patients received post operative opioid tablets (an average of 28 tablets).  However 11% of patients did not fill these prescriptions at all, and only 2 of the 178 patients required refills.

We believe patients experienced less pain than surgeons anticipated.

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Ketamine is being increasingly used in the emergency department (ED) for a variety of conditions, including as an analgesic. While its usage continues to increase, there are limited studies evaluating ketamine as an analgesic in the emergency department.

Most of the studies evaluating ketamine utilized it as an adjunct to an opioid, however, multiple recommendations on blogs and other websites recommend ketamine as a single agent. The purpose of the meta-analysis was to compare the analgesic effect of ketamine compared to an opioid in adult patients presenting with acute pain to the ED.

In this study, we found that ketamine was non-inferior to opioids. We also found that the number of severe adverse events to be similar between both groups.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Aromatase inhibitors are effective in reducing the risk of recurrence in hormone sensitive breast cancer, however they commonly cause joint pain and stiffness that can lead to early discontinuation of treatment. We know that women who stop early do not get the same benefits as those who continue for the full duration.

Acupuncture has been shown to improve a variety of pain syndromes. We conducted a large multicenter trial among women with joint pain on aromatase inhibitors and randomized patients to true acupuncture, sham acupuncture and a waitlist control arm.

We found that acupuncture resulted in more pain reduction than the other 2 control groups. Measuring pain can be challenging in clinical trials. We now know that a meaningful reduction for a patient is 2 points on a 10 point scale. We found that nearly 60 percent of women in the true acupuncture group experienced at least a 2-point reduction in pain, versus 33 percent of the sham acupuncture group and 31 percent of the controls. These results where highly statistically significant.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Gabapentin and pregabalin are used for the management of symptoms such as neuropathic pain, itching, and restless leg syndrome in patients receiving hemodialysis. However, hemodialysis patients may be particularly vulnerable to adverse events related to these agents, which are cleared by the kidney, but there is limited data evaluating their risk in this population.

Gabapentin and pregabalin use were associated with risk for altered mental status, fall, and fracture, and in some cases, even at doses that would be considered safe for use in this population.  Continue reading

Zosano Developing Dermal Patch to Quickly Relieve Migraine Pain

MedicalResearch.com Interview with:

Dr. Peter Schmidt, MD, MSc

Senior Director, medical Affairs and Clinical Development

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: This was a post-hoc analysis of Zosano’s pivotal efficacy trial using its adhesive dermally-applied microarray (ADAM) zolmitriptan formulation, M207. The trial found that M207 was effective versus placebo for the co-primary endpoints of pain freedom and most bothersome symptom (MBS) freedom, both at two hours. The MBS endpoint was just ratified as a new endpoint in the FDA’s February 2018 guidance for acute migraine trials. The stated aim of this new endpoint is “…to better align the study outcome with the symptom(s) of primary importance to patients…” This is logical, as a given migraine patient may not experience all four previous symptom endpoints (pain, photophobia, phonophobia, nausea).

MedicalResearch.com: What is the background for the Applying American Society of Addiction Medicine Performance Measures in Commercial Health Insurance and Services Data study?

Response: In 2016 Cigna announced a collaboration with the American Society of Addiction Medicine (ASAM) to improve treatment for people suffering from substance use disorders and establish performance measures and best practices for addiction treatment. Mining anonymized data from Cigna’s administrative data, Brandeis University researchers have validated a new way to hone in on trouble spots where substance use disorder treatment for opioid, alcohol and other drug dependence is suboptimal, like the way police departments use computers to identify high crime areas in need of greater scrutiny and attention.

The technique uses ASAM-defined performance measures to assess substance use disorder treatment patterns, giving researchers the ability to sort through administrative data and measure to the extent to which patients being treated for opioid or alcohol use disorder are receiving and using evidenced-based medications proven to be effective in improving outcomes and retention in treatment. It also measures whether those patients received support during substance withdrawal – a critical factor in the success of addiction treatment plans. The performance measures were first tested on the Veterans’ Health Administration in 2016 and now, on data from Cigna.

Palmer College of Chiropractic

MedicalResearch.com: What is the background for this study?

Response: Low back pain in the leading cause of physical disability worldwide, with up to 80% of US adults seeking care for this debilitating condition at some point in their lives. Low-back pain is also one of the most common causes of disability in U.S. military personnel.

Although a number of studies have previously evaluated chiropractic care for low back pain, the vast majority had small sample sizes and did not study chiropractic as part of a multi-disciplinary approach to care in real world settings, including the military.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: A great deal of preclinical work in animal models of pain has established that activation of peripheral immune cells or, in the central nervous system (brain and spinal cord), immune cells called “glia” (microglia and astrocytes) play a key role in the establishment and/or maintenance of persistent pain. For instance, if you pharmacologically block activation of these cells in the nervous system, you are able to reduce/inhibit/prevent pain behaviors, e.g. in animals who have received a nerve injury.

This observation is very exciting, because it suggests that blocking neuroinflammation may be a viable way of treating pain. However, the evidence linking human chronic pain with neuroinflammation has so far been limited.

In this study we show, for the first time, that patients with chronic sciatica (that is, back pain that shoots down the leg) demonstrate elevations in the levels of a protein called the translocator protein (TSPO) in the spinal cord and in the nerve roots.

Because TSPO is a marker of neuroinflammation, our results suggest that sciatica is associated with neuroinflammation.

While on average patients do show elevations in the levels of the TSPO, we also saw significant variability across individuals. Importantly, patients that show stronger elevations (in the nerve roots) were those who benefit the most from receiving a local anti-inflammatory treatment (epidural spinal injection). This makes sense: patients whose nerve roots are inflamed benefit from an anti-inflammatory treatment. Those whose nerve roots aren’t inflamed, don’t receive the same benefit. In the latter case, the source of the inflammation and pain may not be the nerve roots, but may be the spinal cord, or, as we showed in a previous paper (Loggia et al., Brain 2015), the brain.  Continue reading
