- Sifting the wheat from the chaff? Evidence for the existence of an asymmetric fibromyalgia phenotype(2020) KAZIYAMA, Helena H.; BARBOUR, Julio; GALHARDONI, Ricardo; SILVA, Valquiria Aparecida da; SIQUEIRA, Silvia R. D. Tesseroli de; LISTIK, Clarice; SANTOS, Gabriel Jose dos; YENG, Lin T.; MARCOLIN, Marco Antonio; RAICHER, Irina; TEIXEIRA, Manoel J.; ANDRADE, Daniel Ciampi deBackground The different phenotypic presentations of fibromyalgia (FM) have been infrequently studied and may have diagnostic and therapeutic implications. The aim of this study was to explore differences between FM patients with classical symmetric (s-FM) presentation and FM patients with marked asymmetric (a-FM) pain. Methods We performed two consecutive cross-sectional studies on FM patients and matched healthy volunteers (HV). FM patients were divided into a-FM (and s-FM groups according to their score of pain intensity on each body side; patients with a difference of >= 40 mm in VAS between left and right sides were classified as a-FM, otherwise classified as s-FM. Participants (FM = 32; HV = 31) were assessed for clinical, cortical excitability (CE), quantitative sensory testing (QST; study 1), and intraepidermal nerve fibre density (IENFD) determinations (study 2). Results While pain intensity did not significantly differ between s-FM and a-FM patients, pain interference in daily activities was significantly higher in the a-FM as compared to the s-FM group (54.7 +/- 8.9 and 37.6 +/- 13.5;p < .0001). PPT was significantly lower in the more painful side of a-FM as compared to the HV (27.7 +/- 7.9 and 49.9 +/- 13.0;p < .0001), while PPT in the less painful side of a-FM was significantly higher than PPT values in the s-FM (35.8 +/- 8.3 and 27.7 +/- 5.5;p = .031). S-FM and a-FM had significantly abnormal intracortical inhibition values on CE measurements compared to HV. There were no significant differences in IENFD between groups. Conclusions Within the current FM criteria, there exist different phenotypes with clinical, psychophysics, and neurophysiological findings that are not related to peripheral IENFD abnormalities. Significance Current fibromyalgia criteria may contain different phenotypes of fibromyalgia based on the lateralization of pain.
- Repetitive Transcranial Magnetic Stimulation in Chronic Pain: A Review of the Literature(2015) GALHARDONI, Ricardo; CORREIA, Guilherme S.; ARAUJO, Haniel; YENG, Lin T.; FERNANDES, Diego T.; KAZIYAMA, Helena H.; MARCOLIN, Marco A.; BOUHASSIRA, Didier; TEIXEIRA, Manoel Jacobsen; ANDRADE, Daniel Ciampi deObjective: To review the literature on the analgesic effects of repetitive transcranial magnetic stimulation (rTMS) in chronic pain according to different pain syndromes and stimulation parameters. Data Sources: Publications on rTMS and chronic pain were searched in PubMed and Google Scholar using the following key words: chronic pain, analgesia, transcranial magnetic stimulation, neuropathic pain, fibromyalgia, and complex regional pain syndrome. Study Selection: This review only included double-blind, controlled studies with >10 participants in each arm that were published from 1996 to 2014 and written in English. Studies with relevant information for the understanding of the effects of rTMS were also cited. Data Extraction: The following data were retained: type of pain syndrome, type of study, coil type, target, stimulation intensity, frequency, number of pulses, orientation of induced current, number of session, and a brief summary of intervention outcomes. Data Synthesis: A total of 33 randomized trials were found. Many studies reported significant pain relief by rTMS, especially high-frequency stimulation over the primary motor cortex performed in consecutive treatment sessions. Pain relief was frequently >30% compared with control treatment. Neuropathic pain, fibromyalgia, and complex regional pain syndrome were the pain syndromes more frequently studied. However, among all published studies, only a few performed repetitive sessions of rTMS. Conclusions: rTMS has potential utility in the management of chronic pain; however, studies using maintenance sessions of rTMS and assessing the effects of rTMS on the different aspects of chronic pain are needed to provide a more solid basis for its clinical application for pain relief.

- Dry needling has lasting analgesic effect in shoulder pain: a double-blind, sham-controlled trial(2021) PAI, Marcus Yu Bin; TOMA, Juliana Takiguti; KAZIYAMA, Helena Hideko Seguchi; LISTIK, Clarice; GALHARDONI, Ricardo; YENG, Lin Tchia; TEIXEIRA, Manoel Jacobsen; ANDRADE, Daniel Ciampi deIntroduction: Myofascial pain syndrome (MPS) affects most patients with chronic shoulder pain. Dry needling (DN) is a common treatment for MPS, but its temporal pattern and sensory effects remain unknown. Objectives: We evaluated in a randomized, sham-controlled study the pattern of analgesic efficacy and local sensory changes of a single session of DN for MPS in patients with chronic shoulder pain. Methods: Patients with chronic shoulder pain were randomized into active (n = 20) or sham (n = 21) groups. A single DN was performed by a researcher blinded to group assignment and pain outcomes. Pain intensity was assessed by the numeric rating score, and sensory thresholds were evaluated with a quantitative sensory testing protocol, including the area of tactile sensory abnormalities 7 days before needling, right before, and 7 days after the intervention. Results: Dry needling led to significant larger pain intensity reduction (from 6.30 +/- 2.05 to 2.40 +/- 2.45 in the active group; P = 0.02, effect size = -1.3 (95% CI [-2.0 to -0.68]); (number necessary to treat = 2.1). Pain reduction scores were significantly different on the second day after needling and persisted so until the seventh day and were accompanied by improvement in other dimensions of pain and a decrease in the area of mechanical hyperalgesia in the active DN group alone (P < 0.05). Conclusion: Active trigger points DN provided analgesic effects compared with sham and decreased the area of local mechanical hyperalgesia. These findings have practical clinical implications and may provide mechanistic insights behind MPS.
- Epigenetics insights into chronic pain: DNA hypomethylation in fibromyalgia-a controlled pilot-study(2017) ANDRADE, Daniel Ciampi de; MASCHIETTO, Mariana; GALHARDONI, Ricardo; GOUVEIA, Gisele; CHILE, Thais; KREPISCHI, Ana C. Victorino; DALE, Camila S.; BRUNONI, Andre R.; PARRAVANO, Daniella C.; MOSCOSO, Ana S. Cueva; RAICHER, Irina; KAZIYAMA, Helena H. S.; TEIXEIRA, Manoel J.; BRENTANI, Helena P.To evaluate changes in DNA methylation profiles in patients with fibromyalgia (FM) compared to matched healthy controls (HCs). All individuals underwent full clinical and neurophysiological assessment by cortical excitability (CE) parameters measured by transcranial magnetic stimulation. DNA from the peripheral blood of patients with FM (n = 24) and HC (n = 24) were assessed using the IlluminaHumanMethylation450 BeadChips. We identified 1610 differentially methylated positions (DMPs) in patients with FM displaying a nonrandom distribution in regions of the genome. Sixty-nine percent of DMP in FM were hypomethylated compared to HC. Differentially methylated positions were enriched in 5 genomic regions (1p34; 6p21; 10q26; 17q25; 19q13). The functional characterization of 960 genes related to DMPs revealed an enrichment for MAPK signaling pathway (n 5 18 genes), regulation of actin cytoskeleton (n = 15 genes), and focal adhesion (n = 13 genes). A gene-gene interaction network enrichment analysis revealed the participation of DNA repair pathways, mitochondria-related processes, and synaptic signaling. Even though DNA was extracted from peripheral blood, this set of geneswas enriched for disorders such as schizophrenia, mood disorders, bulimia, hyperphagia, and obesity. Remarkably, the hierarchical clusterization based on the methylation levels of the 1610 DMPs showed an association with neurophysiological measurements of CE in FM and HC. Fibromyalgia has a hypomethylation DNA pattern, which is enriched in genes implicated in stress response and DNA repair/free radical clearance. These changes occurred parallel to changes in CE parameters. New epigenetic insights into the pathophysiology of FM may provide the basis for the development of biomarkers of this disorder.
- Psychometric validation of the Portuguese version of the Neuropathic Pain Symptoms Inventory(2011) ANDRADE, Daniel Ciampi de; FERREIRA, Karine A. S. L.; NISHIMURA, Carine M.; YENG, Lyn T.; BATISTA, Abrahao F.; SA, Katia de; ARAUJO, Joaci; STUMP, Patrick R. N. A. G.; KAZIYAMA, Helena H.; GALHARDONI, Ricardo; FONOFF, Erich T.; BALLESTER, Gerson; ZAKKA, Telma; BOUHASSIRA, Didier; TEIXEIRA, Manoel J.Backgroud: It has been shown that different symptoms or symptom combinations of neuropathic pain (NeP) may correspond to different mechanistic backgrounds and respond differently to treatment. The Neuropathic Pain Symptom Inventory (NPSI) is able to detect distinct clusters of symptoms (i.e. dimensions) with a putative common mechanistic background. The present study described the psychometric validation of the Portuguese version (PV) of the NPSI. Methods: Patients were seen in two consecutive visits, three to four weeks apart. They were asked to: (i) rate their mean pain intensity in the last 24 hours on an 11-point (0-10) numerical scale; (ii) complete the PV-NPSI; (iii) provide the list of pain medications and doses currently in use. VAS and Global Impression of Change (GIC) were filled out in the second visit. Results: PV-NPSI underwent test-retest reliability, factor analysis, analysis of sensitivity to changes between both visits. The PV-NPSI was reliable in this setting, with a good intra-class correlation for all items. The factorial analysis showed that the PV-NPSI inventory assessed different components of neuropathic pain. Five different factors were found. The PV-NPSI was adequate to evaluate patients with neuropathic pain and to detect clusters of NeP symptoms. Conclusions: The psychometric properties of the PV-NPSI rendered it adequate to evaluate patients with both central and peripheral neuropathic pain syndromes and to detect clusters of NeP symptoms.
