Validity of fibromyalgia survey questionnaire (2016) assessed by telephone interview and cross-cultural adaptation to Brazilian Portuguese language

Abstract Background: To verify the validity of the 2016-revised Fibromyalgia Survey Questionnaire (FSQ) by telephone interview compared to self-administration and to produce a valid version of FSQ in Brazilian Portuguese language. Methods: The Brazilian version of FSQ was produced following the recommendations for cross-cultural adaptation. Validity of Brazilian FSQ self-administration was assessed by checking agreement of its results with fibromyalgia diagnosis according the 1990 American College of Rheumatology (ACR) criteria. Reproducibility and validity of FSQ by telephone were assessed by comparing its results with the previous FSQ self-administration. Results: A Brazilian Portuguese version (FSQ-Brazil) was produced. FSQ-Brazil had good internal consistency (Cronbach's alpha between 0.73 and 0.94). Agreement between the results obtained by self-administration of FSQ-Brazil and by telephone interview was substantial or almost perfect for almost all questions about pain sites and all questions about other somatic symptoms (Cohen's kappa higher than 0.6). There were small but significant bias toward higher scores of widespread pain index and fibromyalgia severity scale in the telephone interview compared to self-administration. Fibromyalgia definition by self-administration and telephone interview with FSQ-Brazil both revealed substantial agreement with the diagnosis based on ACR 1990 criteria (Cohen's kappa 0.62 and 0.65; respectively). Conclusions: FSQ-Brazil demonstrated good internal consistency, reproducibility and validity both by self-administration and by telephone interview. However, caution must be taken with the interpretation of quantitative scores of widespread pain index and symptoms severity scale, which slightly differed according the method (self-administration or interview) in our study.(AU)

Pain catastrophizing is associated with the Val66Met polymorphism of the brain-derived neurotrophic factor in fibromyalgia

Abstract Background: Fibromyalgia (FM) is a musculoskeletal chronic pain syndrome that impacts negatively patient's daily lives. Its pathogenesis is characterized by a complex relationship between biological and psychosocial factors not fully understood yet. Pain catastrophizing is associated with FM and is an important predictor of outcomes. This study aimed to answer two questions: (i) whether the allele and genotype frequencies of BDNF Val66Met (rs6265) polymorphism differs between FM patients and healthy controls (HC); and (ii) if the BDNF Val66Met polymorphism is a factor that predicts pain catastrophizing in FM. Methods: In a cross-sectional design, 108 FM patients and 108 HC were included. FM patients responded to the Brazilian Portuguese version of the Pain Catastrophizing Scale (BP-PCS) to assess pain catastrophizing, as well as other validated tools for anxiety (The State-Trait Anxiety Inventory - STAI), depression (Beck Depression Inventory II -BDI-II) and functional aspects (Fibromyalgia Impact Questionnaire - FIQ; Central Sensitization Inventory validated and adapted for Brazilian population - CSI-BP; Pittsburgh Sleep Quality Index - PSQI; and Resilience Scale). All subjects were genotyped for the BDNF Val66Met polymorphism. Results: Val allele was significantly more frequent in FM patients compared to the control group (p < 0.05). Also, FM patients with Val/Val genotype showed more pain catastrophizing thoughts, and this genotype was significantly associated with magnification and rumination dimensions of BP-PCS (p < 0.05). Furthermore, there were significant differences in levels of anxiety and symptoms of depression, years of education, and the functional situation between the FM and control groups. Conclusions: The findings show an association of BDNF Val66Met polymorphism with pain catastrophizing in FM, which opens new avenues to comprehend the interplay between molecular genetic characteristics and neuroplasticity mechanisms underpinning FM.(AU)

Isokinetic evaluation of the trunk muscle strength in housewives with fibromyalgia: a cross-sectional study

Abstract Background: It is known that physical activity and muscular performance are reduced in fibromyalgia (FM) syndrome. This study aims to compare the performance of trunk muscles in women with FM and healthy controls and evaluate the correlation between trunk muscle strength and FM severity. Methods: Forty-six patients with FM and 42 age- and body mass index-matched healthy housewives without FM were included in the FM and control groups, respectively. The Fibromyalgia Impact Questionnaire (FIQ) was used for the assessment of FM severity. The pain intensity was evaluated using the visual analogical scale (VAS). An isokinetic dynamometer was used to measure the isokinetic trunk muscle strength. The peak torque (PT) values were recorded. The psychological status of the patients was evaluated using the Beck Depression Inventory. Results: There was no statistically significant difference in terms of age, BMI, and BDI scores in two groups (p > 0.05, for all). The isokinetic trunk extensor PT values were significantly lower in the FM group (p = 0.002 for 60°/s, and p < 0.001 for 90°/s and 120°/s) than control group. There was a statistically significant negative correlation between FIQ score and isokinetic extensor muscle parameters. Conclusion: The results indicate that trunk extensor muscles were significantly weaker in FM patients. Trunk extensor muscle strength decreased as FM severity increased in FM patients.(AU)

Determination of the increased risk of developing atrial fibrillation in fibromyalgia syndrome

Abstract Introduction: Atrial fibrillation (AF) is the leading cause of ischemic stroke and is one of the most common arrhythmias. Previous studies have shown that impaired diastolic functions, P wave dispersion (Pd), and prolonged atrial conduction times (ACT) are associated with increased incidence of atrial fibrillation (AF). The aim of this study was to evaluate diastolic functions, Pd, and ACT in fibromyalgia syndrome (FMS) patients to determine whether there is an increase in the risk of developing AF. Methods: The study included a total of 140 female patients (70 FMS group, 70 healthy control group). Pd was evaluated using 12 lead electrocardiography (ECG), and diastolic functions and ACT with echocardiography. The ECG and echocardiographic evaluations were performed by different cardiologists blinded to the clinical information of the subjects. Results: There was no difference between the two groups in laboratory and clinical parameters. Patients with FMS had significantly higher echocardiographic parameters of ACT known as left-sided intra-atrial (13.9 ± 5.9 vs. 8.1 ± 1.8, p < 0.001), right-sided intra-atrial (21.9 ± 8.2 vs. 10.4 ± 3.5, p < 0.001) and interatrial [40 (25-64) ms vs. 23 (14-27) ms p < 0.001] electromechanical interval (EMI) compared with the control group. Pd was significantly greater in the FMS group compared with the control group [46 (29-62) ms vs. 32 (25-37) ms, p < 0.001]. In the FMS group, there was no significant relationship of the echocardiographic parameters of ACT, Pmax and Pd with age, E/A ratio and deceleration time (DT); while all these five parameters were significantly correlated with left atrial dimension, isovolumetric relaxation time (IVRT), fibromyalgia impact questionnaire (FIQ) and visual analogue scale (VAS). There was a strong correlation between FIQ and VAS and echocardiographic parameters of ACT, Pmax and Pd. Conclusions: Impaired diastolic functions, an increase in Pd, and prolongation of ACT were observed in FMS. Current disorders are thought to be associated with an increased risk of AF in FMS. The risk of developing AF increases with the severity of FMS and clinical progression.(AU)

Psychometric properties of Turkish version of Jenkins sleep scale in fibromyalgia syndrome

Abstract Background: Fibromyalgia syndrome (FMS) has adverse effects on the quality of sleep. The aim of this study was to investigate the validity and reliability of Jenkins Sleep Scale (JSS-TR) in Turkish FMS patients. Methods: FMS patients who met the 2016 fibromyalgia diagnostic criteria were included in the study. Clinical and demographic data of the patients were noted. The relationship between this scale and other functional parameters such as Pittsburgh Sleep Quality Index (PSQI), European Quality of Life Scale-5 Dimensions (EQ-5D), Fatigue Severity Scale (FSS), Beck Depression Inventory (BDI) was examined. Fibromyalgia Impact Questionnaire (FIQ) was used to evaluate the functional status of the patients and the progression of the disease. Test-retest reliability was calculated by re-applying the questionnaire to patients at 2-week intervals. Duloxetine treatment was initiated in newly diagnosed patients and sensitivity to change was tested at the end of the treatment. Spearman correlation coefficient was used. P < 0.05 was accepted as significant. Results: Eighty-one FMS patients (71 females, 10 males) were included in the study. The mean age was 44.2 ± 10.7 years. The strongest correlation of JSS-TR was with another sleep questionnaire, PSQI (rho = 0.79, p < 0.0005). The correlation with other functional parameters and FIQ was moderate. In test-retest validity, intraclass correlation coefficient was found to be 0.98 (p < 0.0005). Chronbach α value calculated for internal consistency was found to be 0.741. Conclusions: JSS-TR is a valid, simple and feasible sleep instrument that can be easily applied to FMS patients both in researches and clinical settings.(AU)

Relations between serum magnesium and calcium levels and body composition and metabolic parameters in women with fibromyalgia

Abstract Objective: Correlate serum magnesium (Mg) and Calcium (Ca) levels with body composition and metabolic parameters in women with fibromyalgia (FM). Patients and methods: Cross-sectional study compared with a control group paired by age and body mass index (BMI) of adult women diagnosed with fibromyalgia. All participants went through assessment of their body composition through dual-energy X-ray absorptiometry (DXA) and had blood samples collected for dosing of Mg, Ca, C-reactive Protein (CRP), lipidogram and glycemia. Results: 53 women with FM (average age 48.1 ±8.2 years, average BMI 26.6 ±4.5 kg/m2) and 50 control women (average age 47.1 ±9.9 years, average BMI 25.6 ± 3.6 kg/m2) participated in the study. Serum levels turned out to have inverse correlation with CRP in the FM group (r = −0.29, p = 0.03) and with BMI and glycemia in the control group (r = 0.31; p = 0.02 and r = 0.48; p = 0.0004 respectively). Serum levels of calcium correlated with triglycerides (r = 0.29; p = 0.03) in the FM group and with glycemia in the control group (r = 0.64; p = 0.0001). Conclusions: In patients with FM, magnesemia turned out to have inverse correlation with CRP and calcemia had positive association with triglycerides.(AU)

Percepção e enfrentamento da dor em crianças e adolescentes com fibromialgia juvenil e artrite idiopática juvenil poliarticular / Pain perception and pain coping mechanisms in children and adolescents with juvenile fibromyalgia and polyarticular juvenile idiopathic arthritis

RESUMO Objetivo: Mensurar e comparar a dor musculoesquelética em pacientes com fibromialgia juvenil (FMJ) e em pacientes com artrite idiopática juvenil poliarticular (AIJ); e avaliar e comparar a percepção e o enfrentamento da dor. Métodos: Foram avaliados, em estudo transversal, 150 crianças e adolescentes (e seus respectivos pais), divididos em três grupos: FMJ, AIJ e controles saudáveis. A mensuração e o enfrentamento da dor foram realizados por meio de instrumentos específicos. Para a avaliação da percepção da dor, desenvolveram-se três vinhetas com simulação de situações que pudessem gerar dor: aplicação de injeção, queda de bicicleta e isolamento social. Os pais e os pacientes responderam individualmente quanto à percepção da dor em cada situação. Resultados: As maiores notas de dor, os menores escores de enfrentamento da dor, as maiores notas para a percepção da dor nas vinhetas e os piores índices de qualidade de vida relacionada à saúde foram observados nos pacientes com FMJ, quando comparados aos pacientes com AIJ e aos controles. O mesmo padrão foi observado com os respectivos pais. Conclusões: Pacientes com AIJ e FMJ se comportam diferentemente em relação à percepção da dor e ao desenvolvimento de técnicas para o enfrentamento da dor. A dor deve ser avaliada sob diferentes perspectivas para um planejamento mais individualizado e efetivo do tratamento desses pacientes.

ABSTRACT Objective: To measure and compare musculoskeletal pain in patients with juvenile fibromyalgia (JFM) and polyarticular juvenile idiopathic arthritis (JIA), and to evaluate and compare pain perception and pain coping mechanisms in these patients. Methods: In this cross sectional study, we evaluated 150 children and adolescents, and their respective parents, from 3 different groups: JFM, polyarticular JIA, and healthy controls. Pain intensity and pain coping mechanisms were measured using specific questionnaires. Pain perception was evaluated according to three illustrations simulating situations that might cause pain: a shot, a bicycle fall, and social isolation. The patients' parents also filled out the questionnaires and provided a pain score that matched their child's perception of pain for each illustration. Results: The highest pain scores, the lowest pain coping strategy scores, the highest pain perception scores for all three illustrations, and the worse health related to quality of life indicators were observed in the JFM group, when compared to the JIA and control groups. The same pattern was observed with their parents. Conclusions: Patients with JIA and JFM behave differently in relation to pain perception and the development pain coping mechanisms. Pain should be evaluated from different perspectives for an individualized and efficient treatment of patients.

Does whole body vibration exercise improve oxidative stress markers in women with fibromyalgia?

The objective of this study was to investigate the effect of whole body vibration (WBV) exercise on oxidative stress markers in a group of women with fibromyalgia (FM) compared to a group of healthy women (CT). Twenty-one women diagnosed with FM and 21 age- and weight-matched healthy women were enrolled the study. Plasma oxidative stress markers (primary outcomes) were evaluated at rest and after WBV, and included thiobarbituric acid reactive substances (TBARS), iron reduction capacity (FRAP), superoxide dismutase antioxidant enzymes activity (SOD), and catalase (CAT). At rest, the FM group had higher TBARS (P<0.001) and FRAP (P<0.001), and lower CAT (P=0.005) compared to the CT. In the CT group, the WBV had no effect on TBARS (P=0.559) and FRAP (P=0.926), whereas it increased both SOD (P<0.001) and CAT (P<0.001). In the FM group, the WBV reduced TBARS (p <0.001), FRAP (P<0.001), and CAT (P=0.005), while it increased SOD (P=0.019). There was an interaction effect (moments vs groups) in the TBARS (effect size=1.34), FRAP (effect size=0.93), CAT (effect size=1.45), and SOD (effect size=1.44) (P<0.001). A single trial of WBV exercise improved all oxidant and antioxidant parameters towards a greater adaptation to the stress response in FM women.

Lower limb muscle strength and serotonin receptor gene polymorphism as factors associated in women with fibromyalgia

Abstract Background: Fibromyalgia (FM) is a chronic pain syndrome characterized by generalized skeletal muscle chronic pain. Its etiology is not well defined, because there are several factors that may trigger it such as physical and/or emotional stresses, or a genetic susceptibility, involving serotonergic, dopaminergic and catecholaminergic paths. The objective of this study was to investigate the association between the strength of the lower limb, genetic polymorphism of the serotonin receptor gene HTR2a in women with fibromyalgia. Methods: In this observational study of case-control type 48 women were evaluated who belonged to the group with FM (52 ± 12 years) and 100 women in the control group (58±11 years). Socio demographic and anthropometric data were collected and peripheral blood samples for DNA extraction; genotypic analyzes were performed by means of PCR in real time by TaqMan® system. The lower limb muscle strength was assessed through the test of sitting down and standing up for 30 s. The chi-square test or Fischer Exact was used for possible associations among the variables; the t-test for independent samples was used to compare the averages among the groups; the value of significance adopted was 5%. Results: There was an association between the polymorphism of the HTR2A gene with FM, demonstrating that carriers of the genotype GG have 24.39 times more likely to develop the syndrome (IC95% 5.15-115.47; p = 0.01). It was observed an association between FM and the test to sit and stand up demonstrating that women with fibromyalgia have lower limb muscle strength ( p = 0.01). The study showed that the white race has 3.84 times more likely to develop FM (p = 0.01). Conclusion: The results of this study suggest that women of Caucasian ethnicity with GG genotype or G allele presented greater risk of developing fibromyalgia and that these patients have lower limb muscle strength compared to the control group.

Self-reported disability in women with fibromyalgia from a tertiary care center

Abstract Background: The World Health Organization Disability Assessment Schedule (WHODAS) 2.0 is a generic instrument to assess disability. Pain and psychological factors seem to play a pronounced disabling role in fibromyalgia (FM). There are few studies that investigate the factors associated with disability in patients with fibromyalgia from the patient's perspective. Information about FM disability using self-reported questionnaires is limited. This study aimed to assess the relationship between the ordinal response variable (degree of disability), and four explanatory variables: pain intensity, depression, anxiety, and alexithymia. Methods: One hundred fifteen women with FM were enrolled in the cross-sectional study. For the assessment of disability the WHODAS 2.0 (36-item version) was used. Univariate and multivariate (ordinal logistic regression) analyses were performed to assess the relationship between pain (Visual Analogue Scale), depression and anxiety (Hospital Anxiety and Depression Scale), alexithymia (Modified Toronto Alexithymia Scale) and disability. Results: Disability was detected by global WHODAS score in 114 patients (99%), with the corresponding percentages for mild, moderate and severe disability being 11.3, 46.96 and 40.87%, respectively. Global WHODAS score was more severe among subjects with depression (50 vs 36.4, p < 0.001, effect size = 0.33) and alexithymia (50 vs 33.6, p < 0.001, effect size = 0.38). Pain intensity mean scores for mild, moderate and severe disability were 5.0, 6.1 and 7.3, respectively (p < 0.001, omega-squared = 0.12). Pain intensity explained the global disability degree and its domains except for the cognitive one. Whereas, depression explained cognitive and personal relation domains. On the other hand, alexithymia explained global disability degree and all domains of WHODAS 2.0 questionnaire. Conclusions: Most of the patients with fibromyalgia perceived themselves with moderate to severe disability. The main explanatory variables of the perceived disability were the pain intensity and psychological factors (alexithymia and depression).

Relation between magnesium and calcium and parameters of pain, quality of life and depression in women with fibromyalgia

Abstract Objective: Determine food intake and levels of serum magnesium (Mg) and calcium (Ca) and correlate these minerals with pain, quality of life and depression risk in women with and without fibromyalgia (FM). Patients and methods: Fifty-three women diagnosed with FM and 50 healthy women participated in the study, where all of them had equivalent age and body mass index (BMI). All women underwent anthropometric assessment, physical exams of pain perception threshold and tender point (TP) count, blood sample collection, and filling out of FM impact questionnaire (FIQ), Patient Health Questionnaire-9 (PHQ-9), and 3-day dietary record (DR). Results: Dietary intake of Mg and Ca was substantially lower by women with FM. There were no differences in levels of serum Mg and Ca in the groups under analysis. For the FM group, dietary intake of Mg and Ca had inverse correlation with TP and direct relation with the pain threshold. Conclusions: Although women with FM had lower dietary intake of Mg and Ca, serum levels for these nutrients were not different between the groups. Low dietary intake of minerals correlated with worsened pain threshold parameters.

Suplemento de magnesio y ácido málico para fibromialgia / Magnesium and malic acid supplement for fibromyalgia

INTRODUCCIÓN La fibromialgia es una condición reumática no articular caracterizada por distintos síntomas, donde destacan principalmente el dolor, sensibilidad muscular, fatiga, insomnio, rigidez matinal, depresión y disminución de la funcionalidad cotidiana. Aún no existe claridad respecto de su etiología, pero se ha planteado que la deficiencia de elementos tales como el magnesio podría tener un rol tanto en la fisiopatología de la fibromialgia como también contribuir a sus síntomas clínicos. MÉTODOS Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES Identificamos siete revisiones sistemáticas que en conjunto incluyeron 11 estudios primarios, de los cuales solo uno corresponde a un ensayo aleatorizado. Concluimos que el uso de magnesio y ácido málico en pacientes con fibromialgia tiene poco o nulo impacto en dolor y en los síntomas depresivos.

INTRODUCTION Fibromyalgia is characterized by myalgia and a combination of different symptoms including pain, fatigue, insomnia, morning rigidity, depression and a reduction in every-day functioning. Its aetiology is not clear, but it has been suggested that deficiency in certain minerals such as magnesium may play a role both in the physiopathology and in contributing to the symptoms. METHODS We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS We identified seven systematic reviews which included 11 primary studies of which one was a randomized trial. Our conclusion is that the use of magnesium and malic acid in patients with fibromyalgia makes little or no difference on pain and on depressive symptoms.

Influência da realidade virtual sobre a dor, fadiga, capacidade funcional e qualidade de vida na fibromialgia: estudo de caso / Influence of virtual reality on pain, fatigue, functional capacity and quality of life in fibromyalgia: a case study

Objetivo: Avaliar o efeito da Realidade Virtual (RV) associado a exercícios físicos na qualidade de vida, fadiga, níveis de dor e capacidade funcional em uma mulher com Fibromialgia (FM). Métodos: Trata-se de um estudo de caso que avaliou uma paciente com diagnóstico de FM, antes e após a intervenção com a RV associada a prática de exercícios físicos. Os instrumentos de avaliação utilizadas foram: Questionário de Impacto da Fibromialgia, Questionário de Capacidade Funcional, a Escala Visual analógica de Dor, Escala de Pensamento catastrófico sobre a dor, Escala de severidade da fadiga e avaliação do limiar de dor à pressão sobre os 18 tender points por meio de um algômetro de pressão digital. O tratamento ocorreu durante 6 semanas, com 2 sessões de tratamento por semana, totalizando 12 sessões. Resultados: O estudo proposto mostrou que o tratamento associado a RV promoveu uma melhora no impacto da FM na qualidade de vida da voluntária, uma diminuição na catastrofização da dor e uma diminuição da fadiga. Também foi possível notar uma melhora no limiar de dor a pressão em 16 tender points. Conclusão: Um programa de reabilitação para pessoas com FM que envolva a RV somado a prática de exercícios físicos contribuiu para melhora dos aspectos cognitivo e físico. A associação destas duas terapias foi benéfica, uma vez que estímulos cognitivos e a prática de uma atividade física foi capaz de promover melhora na função, na fadiga, na qualidade de vida e na percepção de dor desses

Objective: The objective of this study was to evaluate the effect of Virtual Reality (VR) associated with physical exercises on quality of life, fatigue, pain levels, and functional capacity in a woman with Fibromyalgia. Methods: This is a case report that evaluated one patient diagnosed with FM before and after the intervention with RV associated with physical exercise. The evaluation scales used were: Fibromyalgia Impact Questionnaire, Health Assessment Questionnaire, Visual Analogue Scale for Pain, Pain Catastrophizing Scale, Fatigue Severity Scale and pressure pain threshold evaluation at the 18 tender points with a digital pressure algometer. Treatment was conducted for 6 weeks, with 2 sessions per week, totaling 12 treatment sessions. Results: The study showed that treatment with VR promoted an improvement in the impact of FM in the volunteer's quality life, a decrease in catastrophic sensation of pain and a decrease in fatigue. It was also possible to notice an improvement in the pressure pain threshold at 16 tender points. Conclusion: A rehabilitation program for people with FM that involves VR combined with the practice of physical exercises contributed to the improvement of cognitive and physical aspects. The association of these two therapies was beneficial, since cognitive stimuli and the practice of a physical activity could promote improvements in function, fatigue, quality of life, and pain perception of these individuals

Serum levels of leptin and adiponectin and clinical parameters in women with fibromyalgia and overweight/obesity

ABSTRACT Objectives The objectives of this study were to evaluate the serum levels of adipokines in women with fibromyalgia with and without overweight/obesity, and to correlate the adipokines levels with clinical parameters associated with fibromyalgia and adipose tissue mass (body fat). Subjects and methods The study included 100 women divided into four groups: (a) fibromyalgia and overweight/obesity; (b) fibromyalgia and normal weight; (c) controls and overweight/obesity; and (d) controls and normal weight. Patients and controls were evaluated for clinical, anthropometric, and fibromyalgia-related parameters. Assessments included serum levels of leptin, adiponectin, monocyte chemoattractant protein-1 (MCP-1), and C-reactive protein (CRP). Levels of adipokines were further adjusted for fat mass. Results Fibromyalgia patients with overweight/obesity or normal weight had no differences in clinical parameters. Unadjusted leptin levels were lower in fibromyalgia patients than controls, a finding that was more remarkable in fibromyalgia patients with overweight/obesity. Leptin levels had no correlation with clinical parameters of fibromyalgia or inflammation markers (MCP-1 and CRP), and adiponectin levels showed no difference between groups. Conclusions No correlation was observed between adjusted leptin levels and clinical parameters of fibromyalgia. Patients with fibromyalgia and overweight/obesity presented lower levels of leptin than controls with overweight/obesity.

EpiFibro (Brazilian Fibromyalgia Registry): data on the ACR classification and diagnostic preliminary criteria fulfillment and the follow-up evaluation / EpiFibro (Registro Brasileiro de Fibromialgia): dados sobre a classificação do ACR e preenchimento dos critérios diagnósticos preliminares e avaliação de seguimento

Abstract Introduction: EpiFibro (Brazilian Epidemiological Study of Fibromyalgia) was created to study Fibromyalgia patients. Patients were included since 2011 according to the 1990 American College of Rheumatology Classification Criteria for Fibromyalgia (ACR1990). Objectives: To determine how many patients still fulfill the ACR1990 and the ACR2010 criteria in 2014; to determine the correlation between the impact of FM and to describe data on the follow-up evaluation. Methods: This is a cross sectional study in a multicenter cohort of patients. The data was collected between 2013 and 2015. Physician included patients that fulfilled the ACR1990 criteria on the date of entry. The follow-up data were considered only for patients with at least two evaluations. A minimally significant change was considered to be a 30% variation of parameters scores. Results: 810 patients’ data were analyzed. Patients presented a mean age of 51.8 ± 11.5 years old. There were 786 female. Most patients met both criteria. There was a greater fulfilling of the ACR2010. There was a moderate correlation between Polysymptomatic Distress Scale and Fibromyalgia Impact Questionnaire. Three hundred fourteen patients with more than one assessment were found, but 88 patients were excluded. Thus, 226 patients with one follow-up monitoring parameter were considered (Fibromyalgia Impact Questionnaire: 222; Polysymptomatic Distress Scale: 199; both: 195). The mean follow-up time was 9.1 ± 7.5 months (1–44). Most patients became stable. Conclusion: InEpiFibro, most patients fulfill simultaneously the ACR1990 and ACR2010. A larger number of patients fulfill the ACR2010 at the time of the evaluation. There was a moderate correlation between the Polysymptomatic Distress Scale and the Fibromyalgia Impact Questionnaire. Most patients remained stable over time.

Resumo Introdução: O EpiFibro (Estudo Epidemiológico Brasileiro de Fibromialgia) foi criado para estudar pacientes com fibromialgia. Foram incluídos pacientes desde 2011 de acordo com os critérios de classificação para a fibromialgia do American College of Rheumatology de 1990 (ACR1990). Objetivos: Determinar quantos pacientes ainda atendem aos critérios ACR1990 e ACR2010 em 2014; determinar a correlação entre o impacto da FM medido pelo Questionário de Impacto da Fibromialgia (FIQ) e pela Polysymptomatic Distress Scale (PDS) e descrever dados sobre a avaliação de seguimento. Métodos: Estudo transversal em uma coorte multicêntrica de pacientes. Os dados foram coletados entre 2013 e 2015. O médico incluiu pacientes que atenderam aos critérios ACR1990 no momento da entrada. Consideraram-se os dados de seguimento apenas dos pacientes com pelo menos duas avaliações. Uma variação de 30% nos escores dos parâmetros foi considerada uma alteração minimamente significativa. Resultados: Analisaram-se os dados de 810 pacientes. Os pacientes apresentaram média de 51,8 ± 11,5 anos. Havia 786 mulheres. A maior parte dos pacientes atendeu a ambos os critérios. Houve um maior atendimento aos critérios ACR2010. Houve uma correlação moderada entre a PDS e o FIQ. Encontraram-se 314 pacientes com mais de uma avaliação, mas 88 pacientes foram excluídos. Assim, foram considerados 226 pacientes com um parâmetro de monitoramento no seguimento. (FIQ: 222; PDS: 199; ambos: 195). O tempo médio de seguimento foi de 9,1 ± 7,5 meses (1 a 44). A maior parte dos pacientes tornou-se estável. Conclusão: No EpiFibro, a maior parte dos pacientes atendia simultaneamente ao ACR1990 e ao ACR2010. Uma maior quantidade de pacientes atendia ao ACR2010 no momento da avaliação. Houve uma correlação moderada. A maior parte dos pacientes manteve-se estável ao longo do tempo.

Frequency of fibromyalgia syndrome in patients with central serous chorioretinopathy / Frequência de síndrome de fibromialgia em pacientes com coriorretinopatia serosa central

ABSTRACT Purpose: To ınvestigate frequency of fibromyalgia syndrome (FMS) among patients with central serous chorioretinopathy (CSCR). Methods: The study included 83 patients with CSCR and 201 age- and sex-matched healthy controls; the mean age was 47.5 ± 11.3 years in the CSCR group (18 women; 21.7%) and 47.2 ± 11.2 years in the control group (44 women; 21.9%). All participants were assessed for FMS based on 2010 American College of Rheumatology diagnostic criteria and for depression and anxiety with the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI). Results: FMS was diagnosed in 35 patients (42.2%) from the CSCR group and in 21 individuals (10.4%) from the control group (p<0.001). It was found in 77.77% of the women (14/18) and 32.3% of the men (21/65) in the CSCR group and in 22.7% of the women (10/44) and 7.0% of the men (11/157) in the control group. Familial stress, BDI and BAI scores were higher in the patients with FMS than in those without. When independent risk factors were evaluated by logistic regression analysis, it was found that only the presence of familial stress was a significant risk factor for FMS. Conclusions: Patients with CSCR should be assessed for the presence of FMS, and this should be taken into consideration when developing a treatment plan. Further studies with a larger sample size are needed to clarify the relationship between FMS and CSCR.

Todos os participantes foram avaliados com base nos critérios de diagnóstico de FMS do American College of Rheumatology de 2010 (ACR), Beck Anxiety Inventory (BAI) e Beck Depression Inventory (BDI). Resultados: A idade média foi 47,53 ± 11,33 anos no grupo CSCR (18 mulheres; 21,7%) e 47,19 ± 11,19 anos (44 mulheres; 21,9%) no grupo controle. FMS foi diagnosticada em 35 pacientes (42,2%) do grupo CSCR e em 21 indivíduos (10,4%) do grupo controle (p<0,001). FMS foi encontrado em 77,77% das mulheres (14/18) e 32,3% dos homens (21/65) no grupo CSCR e em 22,7% das mulheres controles (10/44) e 7,0% dos homens controles (11/157). Estresse familiar, BDI e BAI foram maiores nos pacientes com FMS em comparação com aqueles sem FMS. Quando os fatores de risco independentes foram avaliados por análise de regressão logística, verificou-se que apenas a presença de estresse familiar foi um fator de risco significativo para FMS. Conclusões: Os pacientes com CSCR devem ser avaliados para presença de FMS e a FMS deve ser levada em consideração durante o desenvolvimento de um plano de tratamento. São necessários mais estudos com maior tamanho da amostra para esclarecer relações entre FMS e CSCR.

Depression, sexuality and fibromyalgia syndrome: clinical findings and correlation to hematological parameters / Depressão e sexualidade na síndrome fibromiálgica: achados clínicos e correlação com parâmetros hematológicos

ABSTRACT Fibromyalgia (FM) is characterized by chronic pain and comorbidities. Objective To investigate sexuality and depression in women with FM compared with controls and to correlate the findings with hematological parameters. Methods 33 women with FM and 19 healthy women were included and evaluated with the following instruments: Female Sexual Function Index, Beck Inventory, Visual Analogue Scale, medical history and laboratory exams. Results The prevalence of sexual dysfunction (P = 0.007) and depression (P < 0.001) were higher in the study group than in the control group; they were positively correlated (P = 0.023). The study group showed lower serum concentrations of testosterone, free T4, antinuclear factor, and lower blood hemoglobin and hematocrit. Conclusions FM was associated with high scores of sexual dysfunction and depression, and there were correlations with hematological parameters. We suggest the involvement of immune-inflammatory mediators and FM, which need further investigation to understand their role in FM syndrome and its comorbidities.

RESUMO Fibromialgia (FS) é caracterizada por dor e comorbidades. Objetivo investigar depressão e sexualidade em mulheres com FS comparadas a controles, e correlacionar os achados com parâmetros hematológicos. Métodos 33 mulheres com FS e 19 controles saudáveis foram incluídas e avaliadas através dos seguintes instrumentos: Índice de Função Feminina Sexual, Inventário de Beck, escala visual analógica, história médica e exames laboratoriais. Resultados A prevalência de disfunção sexual (P = 0,007) e depressão (P < 0,001) foram maiores no grupo de estudo do que nos controles; também houve correlação positiva (P = 0,023). O grupo de estudo apresentou menor concentração sérica de testosterona, T4 livre, fator antinuclear e menos concentração de hemoglobina e hematócrito. Conclusões A FS associou-se com altos índices de disfunção sexual e depressão, e houve correlação com os parâmetros hematológicos estudados. Sugere-se o envolvimento de mediadores imuno-inflamatórios na FS, que necessita de maior investigação para a compreensão dos mecanismos tanto na FS e quanto em suas comorbidades.

Temporomandibular disorders in fibromyalgia patients: are there different pain onset? / Disfunção termomandibuar em doentes com fibromialgia: há diferença no início das dores?

ABSTRACT Objective To identify temporomandibular disorders (TMD) symptoms in two groups of fibromyalgia patients according to the temporal relation between the onset of facial pain (FP) and generalized body pain (GBP). Cross-sectional study design: Fifty-three consecutive women with fibromyalgia and FP were stratified according to the onset of orofacial pain: Group-A (mean age 47.30 ± 14.20 years old), onset of FP preceded GBP; Group-B (mean age 51.33 ± 11.03 years old), the FP started concomitant or after GBP. Clinical assessment Research Diagnostic Criteria for Temporomandibular Disorders and the Visual Analogue Scale. Results Myofascial pain with mouth opening limitation (p = 0.038); right disc displacement with reduction (p = 0.012) and jaw stiffness (p = 0.004) were predominant in Group A. Myofascial pain without mouth opening limitation (p = 0.038) and numbness/burning were more common in Group B. Conclusion All patients had temporomandibular joint symptoms, mainly muscle disorders. The prevalence of myofascial pain with limited mouth opening and right TMJ disc displacement with reduction were higher in Group A.

RESUMO Objetivo Identificar sintomas de disfunção temporomandibular (DTM) em dois grupos de pacientes fibromiálgicas, segundo a relação temporal entre o início da dor facial (DF) e das dores generalizadas no corpo (DGC). Estudo transversal: 53 pacientes consecutivas com fibromialgia e DF foram divididas de acordo com o início da dor orofacial: Grupo A (média de idade 47,30 ± 14,20anos), o início da DF precedeu o da DGC; Grupo-B (idade média 51,33 ± 11,03anos), a DF iniciou concomitantemente ou após a DGC. Avaliação clínica: Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) e escala visual analógica (EVA). Resultados Dor miofascial com limitação de abertura bucal (p = 0,038); deslocamento de disco à direita com redução (p = 0,012) e rigidez mandibular (p = 0,004) foram predominantes no Grupo A. Dor miofascial sem limitação de abertura bucal (p = 0,038) e dormência/queimação foram mais comuns no Grupo-B. Conclusão Todos os pacientes tiveram sintomas de DTM, principalmente disfunção muscular. A prevalência de dor miofascial com limitação de abertura bucal e deslocamento de disco à direita com redução foi maior no Grupo A.

Fatores de risco cardiovasculares em pacientes com fibromialgia / Cardiovascular risk factors in patients with fibromyalgia

Objetivo: Verificar os fatores de risco cardiovasculares em pacientes com fibromialgia (FM). Métodos: O estudo foi composto por 40 mulheres diagnosticadas com FM e encaminhadas para o setor de Reabilitação Física do Hospital de Clínicas de Uberlândia. Foi aplicado um questionário do American College of Sports Medicine contendo perguntas sobre histórico familiar; tabagismo; hipertensão; dislipidemia; glicose de jejum alterada; obesidade; sedentarismo e etilismo. Resultados: O sedentarismo teve prevalência de 92,5%, hereditariedade 52,5%, obesidade 50%, hipertensão arterial 45%, dislipidemia 37,5%, tabagismo 25%, etilismo 8% e diabetes 7,5%. Além disso, 60% da amostra apresentou três ou mais fatores de risco, 30% apresentou 2 fatores e 10% apresentou apenas um fator de risco. Conclusão: Pacientes com FM apresentam vários fatores de risco cardiovasculares, desse modo, deve-se orientar tais pacientes à mudança do estilo de vida, a fim de reduzir tais fatores e consequentemente eventos cardíacos futuros, e proporciona melhora do quadro de dor

Objective: To assess the cardiovascular risk factors in patients with fibromyalgia. Methods: The study consisted of 40 women diagnosed with FM and forwarded to the Physical Rehabilitation department at the Hospital of Uberlândia. A survey was applied from the American College of Sports Medicine containing questions about family history, smoking, hypertension, dyslipidemia, impaired fasting glucose, obesity, physical inactivity, and alcohol consumption. Results: The prevalence of physical inactivity was 92.5%, heredity 52.5%, obesity 50%, hypertension 45%, dyslipidemia 37.5%, smoking 25%, alcohol consumption 8%, and diabetes 7.5%. Furthermore, 60% of the sample had three or more risk factors, 30% had 2 factors and 10% had only one risk factor. Conclusion: Patients with FM have multiple cardiovascular risk factors, thus, such patients should be advised to change lifestyle in order to reduce such factors and consequent future cardiac events, and provide improvement of the pain.

Can mastalgia be another somatic symptom in fibromyalgia syndrome?

OBJECTIVE: The purposes of this study were to determine the coexistence of mastalgia and fibromyalgia, to investigate the effects of this combination on pain patterns, and to discuss the status of breast pain in the diagnostic algorithm of fibromyalgia syndrome. METHODS: Sixty-one female patients reporting breast pain during the last three months and 53 female patients diagnosed with fibromyalgia syndrome were enrolled in this study. The Breast Pain Questionnaire was administered to all participants in the mastalgia group and to those in the fibromyalgia syndrome group who had experienced mastalgia during the past three months. The patients in the fibromyalgia syndrome group were evaluated using the 2010 preliminary American College of Rheumatology classification criteria. All of the patients in the mastalgia group were evaluated for the diagnosis of fibromyalgia syndrome by a single physiatrist. The coexistence and pain patterns of mastalgia and fibromyalgia were assessed statistically. RESULTS: Approximately half of the patients with fibromyalgia syndrome (47.2%) reported having mastalgia at the time of admission and 37.7% of the patients with mastalgia met the diagnostic criteria for fibromyalgia syndrome. The patients with mastalgia in the fibromyalgia syndrome group had significantly higher total breast pain scores compared with the women in the mastalgia group. In addition, the patients with fibromyalgia syndrome in the mastalgia group had significantly higher Widespread Pain Index and Symptom Severity Scale scores than the patients with fibromyalgia syndrome. CONCLUSIONS: We suggest that mastalgia can be an aspect of the central sensitivity syndrome and can be added to the somatic symptoms of fibromyalgia.
