Prediction of Differential Pharmacologic Response in Chronic Pain Using Functional Neuroimaging Biomarkers and Support Vector Machine Algorithm - An Exploratory Study.

Arthritis Rheumatol 2021 May 13. Epub 2021 May 13.

Chronic Pain and Fatigue Research Center, Department of Anesthesiology, University of Michigan, Ann Arbor, MI, USA.

Objective: There is increasing demand for prediction of chronic pain treatment outcomes using machine-learning models, in order to improve suboptimal pain management. In this exploratory study, we used baseline brain functional connectivity patterns from chronic pain patients suffering from Fibromyalgia (FM) to predict whether a patient would respond differentially to either milnacipran or pregabalin, two FDA-approved drugs for the treatment of FM.

Methods: FM patients participated in two separate double-blind placebo controlled crossover studies of milnacipran (N=15) and pregabalin (N=13), respectively. Read More

Sex Differences in Opioid Use Disorder Prevalence and Multimorbidity Nationally in the Veterans Health Administration.

J Dual Diagn 2021 May 13:1-11. Epub 2021 May 13.

Department of Psychiatry, Yale School of Medicine, New Haven, Connecticut, USA.

Objective: Opioid use disorder (OUD) is a significant problem among US veterans with increasing rates of OUD and overdose, and thus has substantial importance for service delivery within the Veterans Health Administration (VHA). Among individuals with OUD, several sex- specific differences have begun to emerge regarding co-occurring medical, psychiatric and pain-related diagnoses. The rates of such multimorbidities are likely to vary between men and women with OUD and may have important implications for treatment within the VHA but have not yet been studied. Read More

Serotonergic gene-to-gene interaction is associated with mood and GABA concentrations but not with pain-related cerebral processing in fibromyalgia subjects and healthy controls.

Mol Brain 2021 May 12;14(1):81. Epub 2021 May 12.

Department of Clinical Neuroscience, Karolinska Insitutet, Nobels väg 9, 17177, Stockholm, Sweden.

The neurotransmitter serotonin, involved in the regulation of pain and emotion, is critically regulated by the 5-HT autoreceptor and the serotonin transporter (5-HTT). Polymorphisms of these genes affect mood and endogenous pain modulation, both demonstrated to be altered in fibromyalgia subjects (FMS). Here, we tested the effects of genetic variants of the 5-HT receptor (CC/G-carriers) and 5-HTT (high/intermediate/low expression) on mood, pain sensitivity, cerebral processing of evoked pain (functional MRI) and concentrations of GABA and glutamate (MR spectroscopy) in rostral anterior cingulate cortex (rACC) and thalamus in FMS and healthy controls (HC).

Near-Infrared Spectroscopy (NIRS) of Muscle HbO and MbO Desaturation During Exercise.

Edwin M Nemoto

Adv Exp Med Biol 2021 ;1269:83-86

Department of Neurosurgery, University of New Mexico, Albuquerque, NM, USA.

Continuous noninvasive monitoring of muscle oxygenation has important clinical applications for muscle disorders such as compartmentation syndrome, fibromyalgia, deep vein thrombosis, malignant hyperthermia, and the assessment of training in athletic performance. NIRS has precisely such potential and has been used to detect deep venous thrombosis, evaluate athletic performance, and assess limb reperfusion and revascularization. The aim of this study was to examine the relationship between muscle hemoglobin oxygen (HbO) and myoglobin (MbO) desaturation using NIRS combined with venous blood sampling and HbO desaturation during forearm muscle exercise.

Physical activity in the treatment of fibromyalgia.

Joint Bone Spine 2021 May 4:105202. Epub 2021 May 4.

Centre Multidisciplinaire de Douleur Chronique - CHU UCL Namur - site Godinne, Belgique.

International treatment recommendations for fibromyalgia (FM) highlight the importance of adapted physical activity (APA) combined with patient education. Cognitive and behavioral therapies as well as an interdisciplinary approach can be proposed for more complex or severe clinical situations, with a biopsychosocial vision of rehabilitation. To personalize the rehabilitation's therapeutic approach, a clinician can use simple and validated instruments for measuring physical performance that will highlight levels of physical conditioning, which range from low to very low in FM patients.

Central pain modulatory mechanisms of attentional analgesia are preserved in fibromyalgia.

Pain 2021 May 1. Epub 2021 May 1.

School of Physiology, Pharmacology & Neuroscience, Biomedical Sciences Building, University of Bristol, Bristol, BS8 1TD. Anaesthesia, Pain & Critical Care Sciences, Bristol Medical School, University Hospitals Bristol, Bristol, BS2 8HW. School of Psychological Science, University of Bristol, Bristol, BS8 1TU. University of East Anglia Brain Imaging Centre, School of Psychology, Lawrence Stenhouse Building, Chancellors Drive, NR4 7TJ, United Kingdom.

Abstract: Fibromyalgia is a prevalent pain condition that is associated with cognitive impairments including in attention, memory, and executive processing. It has been proposed that fibromyalgia may be caused by altered central pain processing characterised by a loss of endogenous pain modulation. We tested whether attentional analgesia, where cognitive engagement diminishes pain percept, was attenuated in fibromyalgia patients (n=20) compared to matched healthy controls (n=20). Read More

Dysfunctional energy metabolisms in fibromyalgia compared with healthy subjects.

Mol Pain 2021 Jan-Dec;17:17448069211012833

Seoul Chung Psychiatry Clinic, Seoul, Republic of Korea.

This study aimed to investigate the levels of creatine (Cr) metabolites in the anterior cingulate cortex (ACC), thalamus, and insula of patients with fibromyalgia (FM) using proton magnetic resonance spectroscopy (MRS). The levels of Cr and phosphocreatine (PCr) relative to total Cr (tCr), which includes Cr and PCr, in the ACC, thalamus, and insula were determined using MRS in 12 patients with FM and in 13 healthy controls. The FM group had lower levels of PCr/tCr in the ACC and right insula compared to healthy controls. Read More

The p38/MK2 Axis in Monocytes of Fibromyalgia Syndrome Patients: An Explorative Study.

Medicina (Kaunas) 2021 Apr 19;57(4). Epub 2021 Apr 19.

Department of Rehabilitation Medicine, Hannover Medical School, Carl-Neuberg-Str.1, 30625 Hannover, Germany.

: The aetiology and pathomechanism of fibromyalgia syndrome 12 (FMS) as one of chronic pain syndromes still need to be further elucidated. Mitogen-activated protein kinase (MAPK) pathway has been proposed as a novel approach in pain management. Since the major symptom of fibromyalgia syndrome (FMS) patients is pain, it became of interest whether MAPK pathways, such as the stress-activated p38 MAPK/MK2 axis, are activated in FMS patients.
