Fibromigraine: a cohort study retrospective / Fibroenxaqueca: um estudo de coorte retrospectivo

OBJECTIVE: To diagnose fibromyalgia in patients with migraine and assess the quality of life of these patients. METHODS: A prospective, cross-sectional study was carried out, comparing groups, in a non-randomized sample, consisting of patients diagnosed with migraine. The sample was evaluated using the Widespread Pain Index (WPI) and Symptom Severity Scale (SSS) questionnaires to diagnose fibromyalgia. Quality of life and level of depression were assessed, respectively, using the Headache Impact Test-6 (HIT-6) and Patient Health Questionnaire-9 (PHQ-9). RESULTS: We interviewed 100 patients (5 men and 95 women) diagnosed with migraine, with a mean age of 37.1±11.0 years, ranging from 19 to 64 years. Thirty-four patients (34%) had migraine and fibromyalgia concomitantly. Migraine predominated in females, both in the presence and absence of fibromyalgia. In both groups, there was no difference in headache characteristics. In the group with fibromyalgia, there was a predominance of allodynia and a higher PHQ-9 score (p<0.001). CONCLUSIONS: Patients with migraine are more predisposed to depression when there is an association with fibromyalgia

OBJETIVO: Diagnosticar fibromialgia em pacientes com enxaqueca e avaliar a qualidade de vida desses pacientes. MÉTODOS: Foi realizado um estudo prospectivo, transversal, comparando grupos, em uma amostra não randomizada, composta por pacientes com diagnóstico de enxaqueca. A amostra foi avaliada por meio dos questionários Widespread Pain Index (WPI) e Symptom Severity Scale (SSS) para diagnóstico de fibromialgia. A qualidade de vida e o nível de depressão foram avaliados, respectivamente, por meio do Headache Impact Test-6 (HIT-6) e do Patient Health Questionnaire-9 (PHQ-9). RESULTADOS: Foram entrevistados 100 pacientes (5 homens e 95 mulheres) com diagnóstico de enxaqueca, com idade média de 37,1±11,0 anos, variando de 19 a 64 anos. Trinta e quatro pacientes (34%) apresentavam enxaqueca e fibromialgia concomitantemente. A enxaqueca predominou no sexo feminino, tanto na presença como na ausência de fibromialgia. Em ambos os grupos, não houve diferença nas características da dor de cabeça. No grupo com fibromialgia houve predomínio de alodinia e maior escore no PHQ-9 (p<0,001). CONCLUSÕES: Pacientes com enxaqueca estão mais predispostos à depressão quando há associação com fibromialgia

Low-intensity resistance training promotes a reduction of mechanical hyperalgesia and increase of muscle strength in rats submitted to the diffused chronic muscle pain model / Treinamento resistido de baixa intensidade promove redução da hiperalgesia mecânica e aumento da força muscular em ratos submetidos ao modelo de dor crônica muscular difusa

ABSTRACT BACKGROUND AND OBJECTIVES: Fibromyalgia syndrome (FMS) is characterized by different factors, such as chronic diffuse muscle pain (CDMP), fatigue and psycho-emotional changes. Among the animal models that mimic FMS, the acid saline model is consolidated in the development and maintenance of CDMP. Resistance training (RT) has been an effective method for reducing pain in FMS. Thus, the aim of the present study was to evaluate the effects of resistance training on nociceptive and motor responses in an animal model of chronic diffuse muscular pain. METHODS: Twenty-four male Wistar rats were allocated into four groups: resistance training, RT control, amitriptyline (AMITRIP) and AMITRIP control; all treatment protocols lasted 4 weeks. CDMP was induced in all mice. Then, the animals were treated with low-intensity RT (40% 1 maximum repetition) and AMITRIP (10 mg/kg/day). The mechanical paw withdrawal threshold, locomotor activity and muscle strength were evaluated. RESULTS: Animals treated with both RT and AMITRIP showed an increase in the mechanical paw withdrawal threshold (p<0.05) compared to their controls, suggesting a reduction in mechanical hyperalgesia. There was no improvement in locomotor activity in all groups (p>0.05). Animals with CDMP that underwent RT showed an increase in hindlimb muscle strength (p<0.0001) compared to the RT control group. CONCLUSION: Low-intensity resistance training resulted in antihyperalgesic effects and improved muscle strength in animals submitted to the CDMP model.

RESUMO JUSTIFICATIVA E OBJETIVOS: A síndrome da fibromialgia (SFM) é caracterizada por diferentes fatores, como dor crônica muscular difusa (DCMD), fadiga e alterações psicoemocionais. Dentre os modelos animais que mimetizam a SFM, o modelo de salina ácida é consolidado no desenvolvimento e na manutenção da DCMD. O treinamento resistido (TR) tem sido um método eficaz para redução da dor na SFM. Assim, o objetivo do presente estudo foi avaliar os efeitos do TR na resposta nociceptiva e motora em modelo animal de dor crônica muscular difusa. MÉTODOS: Vinte e quatro ratos machos Wistar foram alocados em quatro grupos: treinamento resistido (TR), controle do TR, amitriptilina (AMITRIP) e controle da AMITRIP, todos os protocolos de tratamento tiveram duração de 4 semanas. A DCMD foi induzida em todos os ratos. Em seguida, os animais foram tratados com TR de baixa intensidade (40% 1 repetição máxima) e AMITRIP (10 mg/kg/dia). Foram avaliados o limiar mecânico de retirada de pata, a atividade locomotora e a força muscular. RESULTADOS: Animais tratados tanto com TR quanto com AMITRIP apresentaram aumento do limiar mecânico de retirada de pata (p<0,05) em relação aos seus controles, sugerindo redução da hiperalgesia mecânica. Não foi observada melhora da atividade locomotora em todos os grupos (p>0,05). Animais com DCMD que realizaram TR obtiveram aumento da força muscular dos membros posteriores (p<0,0001) em comparação ao grupo controle do TR. CONCLUSÃO: Treinamento resistido de baixa intensidade resultou em efeitos anti-hiperalgésicos e melhora da força muscular em animais submetidos ao modelo de DCMD.

Prevalence of fibromyalgia in a Brazilian series of patients with multiple sclerosis / Prevalência de fibromialgia em uma série brasileira de pacientes com esclerose múltipla

Abstract Background The prevalence of pain in patients with multiple sclerosis is remarkable. Fibromyalgia has been considered as one of the forms of chronic pain encompassed in multiple sclerosis, but data are restricted to studies from Europe and North America. Objective To assess the prevalence of fibromyalgia in a series of Brazilian patients with multiple sclerosis and the characteristics of this comorbidity. Methods The present cross-sectional study included 60 consecutive adult patients with multiple sclerosis. Upon consent, participants underwent a thorough evaluation for disability, fatigue, quality of life, presence of fibromyalgia, depression, and anxiety. Results The prevalence of fibromyalgia was 11.7%, a figure similar to that observed in previous studies. Patients with the comorbidity exhibited worse scores on fatigue (median and interquartile range [IQR]: 68 [48-70] versus 39 [16.5-49]; p < 0.001), quality of life (mean ± standard deviation [SD]: 96.5 ± 35.9 versus 124.8 ± 28.8; p = 0.021), anxiety (mean ± SD: 22.7 ± 15.1 versus 13.8 ± 8.4; p = 0.021), and depression (median and IQR: 23 [6-28] versus 6 [3-12.5]; p = 0.034) indices than patients without fibromyalgia. There was a strong positive correlation between depression and anxiety scores with fatigue (r = 0.773 and r = 0.773, respectively; p < 0.001). Conversely, a moderate negative correlation appeared between the Expanded Disability Status Scale (EDSS), fatigue, and depression scores with quality of life (r= −0.587, r= −0.551, r= −0.502, respectively; p < 0.001). Conclusion Fibromyalgia is a comorbidity of multiple sclerosis that can enhance fatigue and decrease quality of life, although depression, anxiety, and disability are factors that can potentiate the impact of the comorbidity.

Resumo Antecedentes A prevalência de dor em pacientes com esclerose múltipla é significativa. A fibromialgia é considerada uma forma de dor crônica encontrada na esclerose múltipla, mas os dados são restritos a estudos europeus e da América do Norte. Objetivo Avaliar a prevalência de fibromialgia em uma série de pacientes com esclerose múltipla e as características desta comorbidade. Métodos O presente estudo transversal incluiu consecutivamente 60 pacientes adultos com esclerose múltipla. Após o consentimento, os participantes foram submetidos à avaliação para determinação de incapacidade, fadiga, qualidade de vida, presença de fibromialgia, depressão e ansiedade. Resultados A prevalência de fibromialgia foi de 11,7%, similar ao observado em estudos prévios. Pacientes com a comorbidade apresentaram piores escores de fadiga (mediana e intervalo interquartil [IIQ]: 68 [48-70] versus 39 [16,5-49]; p < 0,001], qualidade de vida (média ± desvio padrão [DP]: 96,5 ± 35,9 versus 124,8 ± 28,8; p = 0,021), ansiedade (média ± DP: 22,7 ± 15,1 versus 13,8 ± 8,4; p = 0,021) e depressão (mediana e IIQ: 23 (6-28) versus 6 (3-12,5); p = 0,034] do que pacientes sem fibromialgia. Houve correlação positiva forte dos escores de depressão e de ansiedade com a fadiga (r = 0,773 e r = 0,773, respectivamente; p < 0,001). Concomitantemente, houve correlação negativa moderada entre os escores de escala de estado de incapacidade expandida, fadiga e depressão com a qualidade de vida (r = - 0,587, r = - 0,551, r = - 0,502, respectivamente; p < 0,001). Conclusão A fibromialgia é uma comorbidade de esclerose múltipla que pode aumentar a fadiga e diminuir a qualidade de vida, embora depressão, ansiedade e incapacidade sejam fatores potencializadores dessa morbidade associada.

Etiologia e fisiopatologia da fibromialgia / Etiology and pathophysiology of fibromyalgia

A fibromialgia é uma condição crônica de etiologia desconhecida e desvinculada de marcadores laboratoriais específicos para diagnóstico, devido à pobre caracterização da etiopatogenia. Em geral, as alterações comuns à fibromialgia também são observadas em outras condições de dor crônica, tornando a patogênese controversa entre diferentes condições patológicas. A etiologia desconhecida dificulta o diagnóstico e, consequentemente, repercute em um tratamento não tão eficaz de pacientes com fibromialgia. A restauração de desordens sistêmicas confere amplo espectro de possibilidades terapêuticas com potencial de orientar profissionais a estabelecer metas e métodos de avaliação. Diante disso, essa revisão narrativa se volta para debater hipóteses etiológicas e fisiopatológicas no desenvolvimento da fibromialgia.

Fibromyalgia is a chronic condition of unknown etiology unrelated to specific laboratory markers for diagnosis because of poor etiopathogenesis. In general, the changes common to fibromyalgia are also seen in other chronic pain conditions, making the pathogenesis controversial among different pathological conditions. The unknown etiology makes the diagnosis difficult and consequently has repercussions on a not so effective treatment of patients with fibromyalgia. The restoration of systemic disorders provides a wide spectrum of therapeutic possibilities with the potential to guide professionals in establishing goals and evaluation methods. Therefore, this narrative review discusses the etiological and pathophysiological hypotheses involved in the development of fibromyalgia.

Cross-sectional evaluation of socioeconomic and clinical factors and the impact of fibromyalgia on the quality of life of patients during the COVID-19 pandemic

Abstract BACKGROUND: The fibromyalgia impact questionnaire (FIQ) relates to the functional capacity, professional situation, psychological disorders, and physical symptoms, and can identify the factors that determine the impact of the syndrome and characteristics of its carriers; the higher the score, the greater the impact of fibromyalgia on the quality of life. OBJECTIVE: To evaluate the impact of fibromyalgia on the quality of life of individuals with fibromyalgia, who were categorized according to the FIQ during the coronavirus disease pandemic. DESIGN AND SETTING: A cross-sectional study was conducted at an institution of higher education in Taquara, RS, Brazil. METHODS: A quantitative study was carried out, with the application of a sociodemographic and clinical questionnaire, and the FIQ in 163 Brazilian individuals with a medical diagnosis of fibromyalgia. Data were collected using SurveyMonkey software. RESULTS: Of the female carriers, 98.2% were living in urban areas, working, and under pharmacological and complementary treatment. The FIQ results showed that seven of the 10 items had the maximum score. The items "physical function" and "feel good" had intermediate scores, and the item "missed work" had a low score. The average total score was 79.9 points, indicating that fibromyalgia had a severe impact on the participants' lives. A severe impact of fibromyalgia was observed in 61.3% of the participants, a moderate impact in 30.7%, and a low impact in 8%. CONCLUSION: The survey findings suggest a severe impact in the majority of the Brazilian fibromyalgic population.

Diagnosis of fibromyalgia: diagnostic feasibility and accuracy of thermography

INTRODUCTION: Studies have suggested using thermography as a resource to diagnose fibromyalgia, although there has been no evidence confirming this hypothesis so far. OBJECTIVE: To evaluate the sensitivity and specificity of computerized infrared thermography as an auxiliary method for diagnosing fibromyalgia. METHODS: It is a diagnostic accuracy studywith cross-sectional design. One hundred and three individuals were evaluated for global pain using the Visual Analogue Scale. The measurement of pain at tender points was assessed by algometry, and skin temperature was assessed by thermography. To evaluate sensitivity and specificity, the analysis was performed using the Receiver Operating Characteristic Curve, measured by the area under the curve with their respective confidence intervals. RESULTS: Thermography has not been very sensitive or specific for pain (tender points) and diagnosis of fibromyalgia, according to the evaluation of the Receiver Operating Characteristic Curve, with an area under the curve equal to or lower than 0.75. CONCLUSION: In this study the thermography was not sensitive and specific as a tool for diagnosing the fibromyalgia syndrome. This study highlights important clinical implications concerning the current methods for diagnosing it, which, despite all efforts, are still subjective and poorly reproducible.

Relationship between the Widespread Pain Index and the PainMAP software for pain sites measurement in patients with Widespread Pain / Relação entre o Índice de Dor Espalhada e o software PainMAP para medida de localização da dor em pacientes com dor espalhada

ABSTRACT BACKGROUND AND OBJECTIVES: Identifying pain sites is essential to managing patients with Widespread Pain. Several instruments have been developed, including pain drawings, a grid system and computerized methods. However, it is not yet known whether the Widespread Pain Index matches an automated method (painMAP) for quantifying the number of pain areas. Therefore, this study aimed to identify the relationship between the Widespread Pain Index and the painMAP software to measure pain sites in participants with Widespread Pain. METHODS: A pre-planned secondary analysis of data collected from 311 patients with musculoskeletal pain was conducted. The Widespread Pain Index and the painMAP software assessed pain sites. Spearman's correlation coefficient investigated the correlation between the Widespread Pain Index and the painMAP software. RESULTS: A total of 98 participants with Widespread Pain were included in this study. Most participants were female (67; 83.7%), with a mean age of 57,7±11,5 years, mean height of 1.6 (0.1) meters and mean weight of 73.2 (11.8) kilograms. The mean pain intensity was 6.7 (2.0), and the pain duration was 92.3 (96.3) months. The mean number of pain sites in the Widespread Pain Index was 10.1 (3.7), and in the painMAP software, it was 11.7 (8.8). A weak positive correlation (rho = 0.26, 95% CI 0.45 to 0.04, p = 0.022) between the Widespread Pain Index and the painMAP software was found. CONCLUSION: The Widespread Pain Index and the painMAP software showed a weak correlation for assessing pain sites in participants with Widespread Pain.

RESUMO JUSTIFICATIVA E OBJETIVOS: A identificação dos locais de dor é um aspecto essencial no manejo de pacientes com Dor Espalhada. Vários instrumentos foram desenvolvidos, incluindo desenhos de dor, um sistema de grade e métodos computadorizados. No entanto, ainda não se sabe se o Índice de Dor Espalhada coincide com um método automatizado (painMAP) para quantificar o número de áreas de dor. Portanto, este estudo teve como objetivo identificar a relação entre o Índice de Dor Espalhada e o painMAP para medir as áreas doloridas em participantes com esse quadro de dor. MÉTODOS: Uma análise secundária pré-planejada de dados coletados de 311 pacientes com dor musculoesquelética foi realizada. O Índice de Dor Espalhada e o painMAP avaliaram as áreas de dor. O coeficiente de correlação de Spearman foi utilizado para investigar a correlação entre o Índice de Dor Espalhada e o software painMAP. RESULTADOS: Um total de 98 participantes com Dor Espalhada foram incluídos neste estudo. A maioria dos participantes era do sexo feminino (67;83,7%), com média de idade de 57,7±11,5 anos, média de altura de 1,6 (0,1) metros e média de peso de 73,2 (11,8) quilogramas. A média de intensidade da dor foi de 6,7 (2,0) e da duração da dor de 92,3 (96,3) meses. O número médio de áreas de dor no Índice de Dor Espalhada foi de 10,1(3,7) e no software painMAP foi de 11,7 (8,8). Uma correlação positiva fraca (rho=0,26, IC de 95% 0,45-0,04, p=0,022) entre o Índice de Dor Espalhada e o painMAP foi encontrada. CONCLUSÃO: O Índice de Dor Espalhada e o painMAP mostraram correlação positiva fraca para avaliar as áreas de dor em participantes com dor espalhada.

The relationship between serum leptin, insulin-like growth factor-1, and insulin-like growth factor binding protein-3 levels and clinical parameters in primary fibromyalgia patients

SUMMARY OBJECTIVE: The aim of this study was to investigate the levels of leptin, growth hormone, insulin-like growth factor-1, and insulin-like growth factor binding protein-3 and their relations with clinical parameters in patients with primary fibromyalgia and healthy controls. METHODS: Our study was performed on 30 female patients with primary fibromyalgia and 30 healthy controls. The levels of insulin-like growth factor-1 and insulin-like growth factor binding protein-3 were measured by a two-site immunoradiometric assay. The serum level of leptin was measured by the ELISA kit. RESULTS: The serum level of leptin was significantly higher, but the serum levels of insulin-like growth factor-1 were significantly lower in patients with fibromyalgia syndrome than healthy controls (p<0.001). The leptin level was positively correlated with the Visual Analog Scale, Fibromyalgia Impact Questionnaire score, Beck Depression Inventory score, tender point count, age, and duration of disease (p<0.001), but it was negatively correlated with insulin-like growth factor-1 (p<0.001). The insulin-like growth factor-1 level was negatively correlated with age, Visual Analog Scale, Fibromyalgia Impact Questionnaire and Beck Depression Inventory scores, duration of disease, and tender point count (p<0.001). CONCLUSION: Our results indicate that high levels of serum leptin and low levels of serum insulin-like growth factor-1 may play a role in the physiopathogenesis of fibromyalgia and may be related to some symptoms.

Discapacidad funcional en pacientes con fibromialgia en un hospital en Lima, Perú

Introducción: La fibromialgia es un trastorno reumatológico caracterizado por dolor generalizado de localización imprecisa que afecta principalmente a mujeres. Se asocia a fatiga, ansiedad, depresión y la capacidad funcional de estos pacientes se ve afectada por la coexistencia de dichos trastornos. Métodos: Serie de casos de corte transversal con uso de datos secundarios de 126 pacientes con fibromialgia que acudieron a consultorio externo del servicio de reumatología de un hospital en Lima durante febrero de 2020. Se buscó determinar la frecuencia de discapacidad funcional y explorar factores asociados en pacientes con diagnóstico de fibromialgia con o sin depresión. La capacidad funcional y la presencia de síntomas depresivos fueron medidas mediante uso de escalas validadas. Se realizó un análisis multivariado de regresión logística múltiple para valorar si la depresión es un factor de riego independiente de discapacidad. Resultados: La edad tuvo una mediana de 53,5 (RIQ: 46-60) años y 122 participantes eran mujeres, además 42 (33,33%) pacientes presentaban depresión y 76 (60,32%) presentaban discapacidad funcional. En el análisis multivariado, se encontró que la depresión es un factor de riesgo independiente de discapacidad funcional luego de ajustar a diabetes, presencia de 3 o más comorbilidades, intensidad de fatiga y síntomas asociados [OR de 3.09 (1.24 - 7.70); p: 0.015]. Conclusiones: La depresión es un factor independiente para discapacidad funcional en pacientes con fibromialgia.

Background: Fibromyalgia is a rheumatological disorder characterized by generalized pain of imprecise localization that mainly affects women. It is associated with fatigue, anxiety, depression, and functional capacity is greatly affected by the coexistence of these disorders. Methods: It is a series of cross-sectional cases, using secondary data from 126 patients with fibromyalgia who attended the outpatient clinic of a hospital at Lima at the rheumatology service during February 2020. We try to determine the frequency of functional disability and explore associated factors in patients diagnosed with fibromyalgia with or without depression. Functional capacity and the presence of depressive symptoms were measure by validated scales. A multivariate multiple logistic regression analysis was performed to assess whether depression is an independent risk factor for disability. Results: The age had a median of 53.5 (IQR: 46-60) years, 122 participants were women. In addition, 42 (33.33%) patients had depression and 76 (60.32%) patients had functional disability. In the multivariate analysis, it was found that depression is an independent risk factor for functional disability after adjusting for diabetes, presence of 3 or more comorbidities, intensity of fatigue and associated symptoms [OR 3.09 (1.24 - 7.70); p: 0.015]. Conclusions: Depression is an independent factor for functional incapacity in patients with fibromyalgia.

Fibromialgia e disfunção temporomandibular: uma revisão de escopo / Fibromyalgia and temporomandibular disorder: a scoping review

A fibromialgia é uma síndrome complexa com alterações nociplásticas, caracterizadas por hiperalgesia e alodinia, frequentemente acompanhada pela presença de dor orofacial. Estudos têm demonstrado alta prevalência de disfunção temporomandibular (DTM) em pacientes fibromiálgicos, como fator etiológico ou agravante. O objetivo desta revisão de literatura foi identificar os mecanismos modulatórios comuns à fibromialgia e à DTM, e identificar diferentes modalidades de tratamento para os pacientes fibromiálgicos. Foram utilizados 69 artigos dos últimos 5 anos, além de 4 artigos conceituais anteriores a este período. Identificou-se que os principais fármacos utilizados para os sintomas de fibromialgia são pregabalina, amitriptilina, antidepressivos duais, tramadol, baixas doses de naltrexona e canabinoides. A associação de fármacos pode ser útil para aumentar a eficácia do tratamento e reduzir as doses dos mesmos. Por outro lado, novas terapias não farmacológicas, como as técnicas modulatórias não-invasivas, surgem como opções promissoras, promovendo alterações neuroplásticas importantes no tratamento. Conclusão: Há diversas opções terapêuticas farmacológicas e não-farmacológicas disponíveis no tratamento do paciente fibromiálgico para o especialista em DTM. Portanto, a combinação de diferentes abordagens pode auxiliar na obtenção de um protocolo individualizado, adequado às necessidades do paciente.

Fibromyalgia is a complex syndrome with nociplastic changes, characterized by hyperalgesia and allodynia, often accompanied by the presence of orofacial pain. Studies have shown a high prevalence of temporomandibular disorders (TMD) in fibromyalgia patients, as an etiological or aggravating factor. The aim of this review was to identify the modulatory mechanisms common to fibromyalgia and TMD, and to identify different treatment modalities for fibromyalgia patients. 69 articles from the last five years were included, in addition to 4 conceptual articles prior to this date. The main drugs used for fibromyalgia symptoms are pregabalin, amitriptyline, dual antidepressants, tramadol, low-dose naltrexone and cannabinoids. The combination of drugs may be useful in improving treatment efficacy and for reducing the drug's dose. On the other hand, new non-pharmacological therapies, such as non-invasive modulatory techniques, appear as promising options for treatment, promoting important neuroplastic alterations. Conclusion: Several pharmacological and non-pharmacological therapeutic alternatives are available for specialists in TMD. Therefore, combining therapy approaches can help create individualized protocols that are more effective at meeting the demands of fibromyalgia patients.

Correlation between levels of perceived stress and depressive symptoms in the functional disability of patients with fibromyalgia

SUMMARY OBJECTIVE: The aim of this study was to evaluate the factors that are most correlated with the levels of functional disability in patients with fibromyalgia. METHODS: This is a cross-sectional descriptive study in which 42 patients diagnosed with fibromyalgia according to the criteria of the American College of Rheumatology reported their status using the following questionnaires: the Beck Depression Inventory, the Perceived Stress Scale 14, the Revised Fibromyalgia Impact Questionnaire, the Visual Analog Pain Scale, and the Health Assessment Questionnaire. RESULTS: Moderate to severe levels of depression (Beck Depression Inventory: 22.35±10.39), moderate to severe functional disability (Health Assessment Questionnaire: 1.28±0.58), and high levels of stress (Perceived Stress Scale 14: 31.59±10.02) were found. The correlation adjusted by multiple regression as a function of the Health Assessment Questionnaire indicated a negligible to weak positive correlation with perceived stress (r=0.11), while a moderately strong positive correlation was observed with the Visual Analog Pain Scale (r=0.55). Regarding physical exercise, one of the pillars of the treatment, a moderate negative correlation was found with the Health Assessment Questionnaire (r=-0.4). CONCLUSION: The pain levels were moderately influenced by depression severity. The factors most linked to functional disability are due to the pain levels but not to the perception of stress.

Práticas corporais e o tratamento interdisciplinar de pessoas com fibromialgia: a dádiva do cuidado / Bodily practices and the interdisciplinary treatment of people with fibromyalgia: the gift of care

Resumo A fibromialgia é uma síndrome reumática caracterizada por dor musculoesquelética crônica e difusa que apresenta desafios diagnósticos e terapêuticos à racionalidade médica ocidental. Estudos ressaltam o papel do tratamento interdisciplinar (TI) e das práticas corporais de saúde (PCS) em termos de cuidado em saúde e acolhimento. Os atos de dar, receber e retribuir dádivas simbólicas de cuidado fornecem sociabilidade, reconhecimento e legitimidade no campo da saúde. O objetivo deste artigo é compreender o TI e as PCS como um sistema de troca de dádivas de cuidado em saúde que se estabelece entre pessoas diagnosticadas com fibromialgia e profissionais de saúde. Trata-se de um estudo qualitativo realizado mediante aplicação de entrevista aberta e observação em campo com oito pessoas diagnosticadas com fibromialgia e questionário semiaberto com nove profissionais de saúde. A Análise do Conteúdo resultou na construção de uma categoria temática: "O ciclo da tripla obrigação da dádiva do cuidado em saúde". A constituição da dádiva no processo de cuidado em saúde ocorreu mediante um deslocamento afetivo-terapêutico ao próximo, dom da hospitalidade e dom do reconhecimento. Em síntese, foi possível perceber a relevância do TI e das PCS como circuitos de reciprocidade capazes de construir novos usos sociais do corpo nas instâncias sociais da vida.

Abstract Fibromyalgia is a rheumatic syndrome characterized by chronic and diffuse musculoskeletal pain that presents diagnostic and therapeutic challenges to Western medical rationality. Studies highlight the role of interdisciplinary treatment (IT) and corporal practices of health (CPH) in terms of health care and reception. The acts of giving, receiving, and returning symbolic gifts of care provide sociability, recognition, and legitimacy in the health field. The objective of this article is to understand IT and CPH as a system for exchanging health care gifts that is established between people diagnosed with fibromyalgia and health professionals. This is a qualitative study carried out by applying an open interview and carrying out field observation with eight people diagnosed with fibromyalgia and a semi-open questionnaire with nine health professionals. Content Analysis led to the elaboration of a thematic category: "The triple obligation cycle of giving health care." The constitution of the gift in the health care process occurred by an affective-therapeutic displacement to the other, a gift of hospitality, and a gift of recognition. In summary, it was possible to perceive the relevance of IT and CPH as circuits of reciprocity capable of building new social uses of the body in social instances of life.

Estudo comparativo da qualidade de vida de doentes com lúpus, artrite reumatoide e fibromialgia / Comparative study of quality of life in rheumatoid arthritis, systemic lupus erythematosus and fibromyalgia

Introdução: Doenças reumatológicas são enfermidades que acometem o sistema locomotor e afetam a qualidade de vida dos portadores. Objetivos: Comparar a qualidade de vida naqueles com lúpus, artrite reumatoide e fibromialgia. Métodos: Estudo observacional no qual foi aplicado o Questionário de Qualidade de Vida SF-36 em 136 pacientes diagnosticados com lúpus, artrite reumatóide e fibromialgia. Resultados: Os com lúpus apresentaram menor limitação funcional e os artrite reumatóide apresentaram mais dor. A avaliação do estado geral de saúde (p=0,26), da vitalidade (p=0,09), da aspectos sociais (p=0,44), saúde emocional (p=0,82) não demonstraram relevância estatística. Conclusão: As 3 doenças reumáticas apresentam diminuição da QoL, mas os com mais dor foram os com artrite reumatóide, e os com menor limitação funcional os de lúpus.

Background: Rheumatologic illnesses are diseases that affect the locomotor system and decrease patient's quality of life. Objective: To compare quality of life in patients diagnosed with lupus, rheumatoid arthritis and fibromyalgia. Methods: Cross-sectional study with application of the SF-36 Quality of Life Questionnaire to 136 patients diagnosed with lupus, rheumatoid arthritis and fibromyalgia. Results: Patients with lupus had lower functional limitation and those with rheumatoid arthritis presented more pain. The assessment of general health status (p=0.26), vitality (p=0.09), social aspects (p=0.44), emotional health (p=0.82) did not show statistical relevance. Conclusion: The 3 rheumatic diseases showed a decrease in quality of life, but the one with the most pain was rheumatoid arthritis, and the lowest functional limitation was found in lupus.

Prevalence of migraine in patients with fibromyalgia / Prevalência de enxaqueca em pacientes com fibromialgia

Objective: To evaluate the prevalence of migraine in patients with fibromyalgia and the impacts of these comorbidities on the daily life of patients. Methods: Questionnaires were applied to fibromyalgia patients. The questionnaires were applied through a Google forms application link and in person, printed. We used FIQ, PHQ-9, and ID migraine. And for patients with a positive ID migraine, we applied the Midas subsequently. Results: Seventy fibromyalgia patients were recruited, age of 47.31 ± 14.5 years. Sixty-five (92.86%) were female and 5 (7.14%) were male. We obtained a prevalence of 60% (n = 42) of migraine associated with fibromyalgia. Among the analyzed variables, severity of depression (p = 0.007), aggregate severity of depression (p = 0.004), and impact of fibromyalgia (p = 0.008) were significantly associated. Among the migraine patients, the vast majority, 34/42 (80.95%), were classified as having severe disability. Conclusion: There is a high prevalence of migraine in patients with fibromyalgia that has an associated impact on patients' lives, which makes clinical and psychosocial management of these patients necessary.

Objetivo: Avaliar a prevalência de enxaqueca em pacientes com fibromialgia e os impactos dessas comorbidades no cotidiano dos pacientes. Métodos: Questionários foram aplicados a pacientes com fibromialgia. Os questionários foram aplicados por meio de link de aplicativo Google Forms e presencialmente, impressos. Usamos FIQ, PHQ-9 e enxaqueca ID. E para pacientes com enxaqueca ID positiva, aplicamos o Midas posteriormente. Resultados: Foram recrutados 70 pacientes com fibromialgia, idade de 47,31 ± 14,5 anos. Sessenta e cinco (92,86%) eram do sexo feminino e 5 (7,14%) do sexo masculino. Obtivemos uma prevalência de 60% (n = 42) de enxaqueca associada à fibromialgia. Entre as variáveis ​​analisadas, a gravidade da depressão (p = 0,007), a gravidade agregada da depressão (p = 0,004) e o impacto da fibromialgia (p = 0,008) foram significativamente associadas. Entre os pacientes com enxaqueca, a grande maioria, 34/42 (80,95%), foi classificada como portadora de incapacidade grave. Conclusão: Existe uma elevada prevalência de enxaqueca em pacientes com fibromialgia que tem impacto associado na vida dos pacientes, o que torna necessário o manejo clínico e psicossocial destes pacientes.

Association of low-dose naltrexone and transcranial direct current stimulation in fibromyalgia: a randomized, double-blinded, parallel clinical trial

Abstract Introduction Fibromyalgia is a complex, generalized, and diffuse chronic musculoskeletal pain. Pharmacological approaches are widely used to relieve pain and increase quality of life. Low-Dose Naltrexone (LDN) was shown to increase the nociceptive threshold in patients with fibromyalgia. Transcranial Direct Current Stimulation (tDCS) is effective for pain management. Objective The purpose of this study was to evaluate the analgesic and neuromodulatory effects of a combination of LDN and tDCS in patients with fibromyalgia. Methods This was a randomized, double-blinded, parallel, placebo/sham-controlled trial (NCT04502251; RBR-7HK8N) in which 86 women with fibromyalgia were included, and written informed consent was obtained from them. The patients were allocated into four groups: LDN + tDCS (n = 21), LDN + tDCS Sham (n = 22), placebo + tDCS (n = 22), and placebo+tDCS Sham (n = 21). The LDN or placebo (p.o.) intervention lasted 26 days; in the last five sessions, tDCS was applied (sham or active, 20 min, 2 mA). The following categories were assessed: sociodemographic, Visual Analog Pain Scale (VAS), Pain Catastrophizing Scale (PCS), State-Trait Anxiety Inventory (STAI), Fibromyalgia Impact Questionnaire (FIQ), Beck Depression Inventory (BDI-II), Profile of Chronic Pain Scale (PCP:S), Pain Pressure Threshold (PPT), and Conditioned Pain Modulation (CPM). Blood samples were collected to analyze BDNF serum levels. Results At baseline, no significant difference was found regarding all measurements. VAS pain was significantly reduced in the LDN + tDCS (p = 0.010), LDN + tDCS Sham (p= 0.001), and placebo+tDCS Sham (p= 0.009) groups. In the PCP:S, the LDN+tDCS group showed reduced pain frequency and intensity (p= 0.001), effect of pain on activities (p= 0.014) and emotions (p= 0.008). Depressive symptoms reduced after all active interventions (p > 0.001). Conclusion Combined LDN+tDCS has possible benefits in reducing pain frequency and intensity; however, a placebo effect was observed in pain using VAS, and further studies should be performed to analyze the possible association.

"Zooming" in the association between rosacea and fibromyalgia syndrome: ıs it worth mentioning?

SUMMARY OBJECTIVE: We aimed to detect the frequency of fibromyalgia syndrome in patients with rosacea and determine whether this frequency was affected by the severity of rosacea and the quality of life. METHODS: In this prospective, controlled, cross-sectional study, a total of 94 consecutive rosacea cases and 87 age- and sex-matched controls were enrolled. The severity of rosacea was assessed in light of the findings of the National Rosacea Society Ethics Committee. Dermatology Life Quality Index and Rosacea-specific Quality-of-Life instrument had been applied to the cases of rosacea. The diagnosis of fibromyalgia syndrome was established according to the 2016 revised fibromyalgia diagnostic criteria, and the Fibromyalgia Impact Questionnaire was used to determine the functional disability. RESULTS: The frequency of fibromyalgia syndrome was higher in the rosacea group than in the control group (p=0.01), and Dermatology Life Quality Index and Rosacea-specific Quality-of-Life instrument were higher in patients with rosacea with fibromyalgia syndrome (p=0.006 and p=0.004, respectively). A statistically significant weak positive correlation was observed between Dermatology Quality-of-Life Index, Rosacea-specific Quality-of-Life instrument, and Fibromyalgia Impact Questionnaire; symptom severity scale scores; and fibromyalgia score (r=0.35, r=0.259, and r=0.32 and r=0.376, r=0.305, and r=0.312, respectively). CONCLUSION: The patients with rosacea have higher rates and disability scores of fibromyalgia syndrome than healthy controls, independent of rosacea severity, and quality of life is correlated with fibromyalgia scores. We might point out that fibromyalgia syndrome accompanying rosacea has more restrictions in their daily routine activities than rosacea alone. As such, physicians should be aware of the possible coexistence of rosacea and fibromyalgia syndrome.

Fibromyalgia from the gender perspective: triggering, clinical presentation and coping / La fibromialgia desde la perspectiva de género: desencadenamiento, presentación clínica y afrontamiento / A fibromialgia na perspectiva de gênero: desencadeamento, clínica e enfrentamento

ABSTRACT Objective: to identify the gender-based differences regarding triggering, clinical presentation and coping of fibromyalgia. Method: an integrative literature review of the narrative type and conducted in five stages, about how research studies discuss the gender-based differences regarding fibromyalgia. It was carried out in November 2022 with the fibromyalgia/fibromialgia and gender/gênero descriptors in the LILACS, MEDLINE, BDENF and IBECS databases via BVS and PubMed. The studies included were those published in the last 10 years, available in full and of free access, in English, Portuguese and Spanish. Results: a total of 16 research studies conducted in United States, Spain, Mexico, Portugal, Egypt, Israel, Italy and Colombia were analyzed. No studies were found in Brazil, an only one of them includes a nurse as author. There is a prevalence of fibromyalgia in females and it is agreed that belonging to this gender can be a risk factor for the disease, due to the lower pain threshold and greater sensitivity to pressure and temperature. Men and women have different pain perceptions and experiences, which can generate underdiagnosis among the former. There are few male participants in the research studies. Only one survey addressed the transgender population. Conclusion: there are divergent conclusions, with controversial data and hypotheses to explain the diagnostic disparity between the genders, and the low number of diagnosed men impacts on research studies. There is a broad field to be explored in Brazil about this topic and there is an evident need for research studies with transgender people. Analyses that correlate all genders may help reorganize fibromyalgia management to promote the patients' well-being and quality of life.

RESUMEN Objetivo: identificar las diferencias de género en relación con el desencadenamiento, la presentación clínica y el afrontamiento de la fibromialgia. Método: revisión integradora de la literatura de tipo narrativa, realizada en cinco etapas sobre la forma en la que los trabajos de investigación debaten las diferencias de género en la fibromialgia. La revisión se condujo en noviembre de 2022 con los descriptores fibromialgia/fibromyalgia y gênero/gender, en las bases de datos LILACS, MEDLINE, BDENF e IBECS a través da BVS y PubMed. Se incluyeron estudios publicados en los últimos 10 años, disponibles en su texto completo, de acceso gratuito y en portugués, inglés y español. Resultados: se analizaron 16 trabajos de investigación realizados en Estados Unidos, España, México, Portugal, Egipto, Israel, Italia y Colombia. No se encontraron estudios provenientes de Brasil y solamente uno de ellos incluía a un enfermero entre sus autores. Se registra prevalencia de fibromialgia en el sexo femenino y se concuerda que pertenecer a este género puede ser un factor de riesgo para padecer la enfermedad, debido al umbral de dolor más bajo y a la mayor sensibilidad a la presión y a la temperatura. Los hombres y las mujeres tienen distintas percepciones y experiencias en relación con el dolor y eso puede generar subdiagnóstico en los hombres. Se detecta un bajo muestreo masculino en los trabajos de investigación. Solamente uno analizó a la población transgénero. Conclusión: se registran conclusiones divergentes, con datos controversiales e hipótesis para explicar la disparidad diagnóstica entre los géneros; además, la escasa cantidad de hombres diagnosticados ejerce un efecto en los trabajos de investigación. Existe un campo a ser explorado en Brasil sobre este tema y se hace evidente la necesidad de realizar trabajos de investigación con personas transgénero. Análisis que correlacionen los géneros podrán ayudar a reorganizar el manejo de la fibromialgia para promover el bienestar y la calidad de vida de los pacientes.

Há prevalência da fibromialgia no gênero feminino e concordância de que pertencer a este gênero pode ser um fator de risco para a doença, pelo menor limiar de dor e maior sensibilidade à pressão e temperatura. Homens e mulheres têm percepções e experiências diferentes da dor e isto pode gerar subdiagnóstico em homens. Há baixa amostragem masculina nas pesquisas. Somente uma pesquisa abordou a população transgênera. Conclusão: há conclusões divergentes, com dados controversos e hipóteses para explicar a disparidade diagnóstica entre os gêneros e o baixo número de homens diagnosticados impacta nas pesquisas. Há um campo a ser explorado no Brasil sobre este tema e se evidencia necessidade de pesquisas com transgêneros. Análises que correlacionem os gêneros podem ajudar a reorganizar o manejo da fibromialgia para promover o bem-estar e qualidade de vida dos pacientes.

Physical activity and quality of life of patients with fibromyalgia

Background: Fibromyalgia Syndrome (FMS) has been linked to decreased social functioning, poor mental health, and quality of life (QOL). Increased physical functioning and activity can result in improvements in social, mental and overall health, as well as lowered depression and anxiety levels. Objectives: The aim of this study was to determine physical activity levels and QOL amongst patients diagnosed with fibromyalgia in the Johannesburg region of South Africa. Methods: The research design was cross-sectional. Descriptive and quantitative data were collected. FMS patients (n=38) completed an online questionnaire on the Google Forms platform. The questionnaire was comprised of four components, namely Demographics, the Global Physical Activity Questionnaire (GPAQ), the Fibromyalgia Impact Questionnaire (FIQR), and the Short Form-36 (SF-36). During data analysis, descriptive characteristics and correlations were computed. The significance level was set at p ≤ 0.05. Results: Results revealed high FIQR scores (67%) accompanied with low QOL scores (<50% in all domains). There was no correlation between physical activity and FIQR, and physical activity and QOL. Conclusion: High scores on the impact of FMS were associated with lower overall QOL scores. However, the relationship between physical activity, and the impact of FMS and QOL remain inconclusive.
