Publication date: Available online 25 June 2019Source: Microbes and InfectionAuthor(s): Elisabetta Bianchi, Lars RoggeAbstractChronic inflammatory diseases such as rheumatoid arthritis, inflammatory bowel disease, spondyloarthritis and psoriasis cause significant morbidity and are a considerable burden for the patients in terms of pain, impaired function and diminished quality of life, as well as for society, because of the associated high health-care costs, and loss of productivity. Our limited understanding of the pathogenic mechanisms involved in these diseases currently hinders early diagnosis and the development of mo...

In this study, we tested the hypotheses that PVD compared with healthy controls (HCs) would demonstrate gray matter volume (GMV) alterations in regions associated with sensorimotor, corticothalamic, and basal ganglia circuits. We also tested the replicability of previously reported gray matter increases in basal ganglia and hippocampal volumes in PVD vs HCs. In addition, disease specificity of GMV alterations were examined by comparing PVD with another chronic pain disorder. Finally, we examine whether GMV alterations are correlated with symptom measures. Structural magnetic resonance imaging was obtained in 119 premenopau...

Chronic eye pain, which has previously been assumed to be due to ocular surface abnormalities (ie, “dry eye [DE] disease”), has recently garnered attention as a potential indicator of neuropathic ocular pain in some patients. The purpose of this study was to evaluate the psychometric properties of a modified version of the Neuropathic Pain Symptom Inventory in individuals with eye pain (NPSI-Eye). Enrolled participants (n = 397) completed the NPSI-Eye, general pain severity questionnaires, DE symptom report, and psychological health indices. Participants also underwent mechanical pain sensitivity testing of the...

This study documents the establishment of PaedePPOC and presents baseline and initial outcome data. Binational consensus meetings determined the measures. Governance structures, collection protocols, information technology, site-specific logistics, and onsite training were achieved within 18 months. Children and parents complete baseline and progress questionnaires. Seven of 10 Australasian services provided data to PaedePPOC, with 1432 patients enrolled until June 2018. At baseline, patients were 12.4 ± (3.0) years, 68% female, 93% Australian-born, and 5% Aboriginal and/or Torres Strait Islander people. Most had mo...

Clinicians report reluctance to deliver opioid-tapering advice to patients with chronic pain, in part due to concerns that patients will be angry and dissatisfied. An experiment was conducted to examine chronic pain patients' emotional and attitudinal responses to simulated opioid-tapering advice. Patients scheduled for an initial assessment at a tertiary pain clinic and currently taking opioid medications for pain (N = 196) were randomly assigned to view video footage of a standardized patient receiving 1 of 3 forms of treatment advice: (1) stay on current medication (2) change to a different pain medication, or (3) taper...

Although several studies have found that chronic pain is characterized by increased cross-network connectivity between salience network, sensorimotor network, and default mode network (DMN), a large sample-size investigation allowing for a more reliable evaluation of somatotopic specificity and subgroup analyses with linkage to clinical pain intensity has been lacking. We enrolled healthy adults and a large cohort of patients (N = 181) suffering from chronic low back pain (cLBP). To specifically link brain connectivity with clinical pain intensity, patients were scanned at baseline and after performing physical maneuvers t...

Diffuse noxious inhibitory controls (DNICs) is a pain-inhibits-pain phenomenon demonstrated in humans and animals. Diffuse noxious inhibitory control is diminished in many chronic pain states, including neuropathic pain. The efficiency of DNIC has been suggested to prospectively predict both the likelihood of pain chronification and treatment response. Little is known as to why DNIC is dysfunctional in neuropathic pain. Here, we evaluated DNIC in the rat L5/L6 spinal nerve ligation (SNL) model of chronic pain using both behavioral and electrophysiological outcomes. For behavior, nociceptive thresholds were determined using...

Inhibition of voltage-gated calcium (CaV) channels is a potential therapy for many neurological diseases including chronic pain. Neuronal CaV1/CaV2 channels are composed of α, β, γ and α2δ subunits. The β subunits of CaV channels are cytoplasmic proteins that increase the surface expression of the pore-forming α subunit of CaV. We targeted the high-affinity protein–protein interface of CaVβ's pocket within the CaVα subunit. Structure-based virtual screening of 50,000 small molecule library docked to the β subunit led to the identification of 2-(3,5-dimethylisoxa...

Chronic pain affects 1 in 5 people and has been shown to disrupt attention. Here, we investigated whether pain disrupts everyday decision making. In study 1, 1322 participants completed 2 tasks online: a shopping-decisions task and a measure of decision outcomes over the previous 10 years. Participants who were in pain during the study made more errors on the shopping task than those who were pain-free. Participants with a recurrent pain condition reported more negative outcomes from their past decisions than those without recurrent pain. In study 2, 44 healthy participants completed the shopping-decisions task with and wi...
