The influence of depression on personality traits in patients with fibromyalgia: a case-control study.

OBJECTIVES: We developed this study to investigate the association of fibromyalgia with personality traits, controlling for depression and other potential confounders. METHODS: We assessed personality traits using the Cloninger's Temperament and Character Inventory (TCI) in 78 female patients with fibromyalgia and in a control group of 78 subjects without fibromyalgia. The Mini-International Neuropsychiatric Interview was used to assess depression and anxiety diagnoses. To investigate the association between fibromyalgia and the Cloninger's Temperament and Character Inventory we performed unadjusted and adjusted analyses of covariance, using the TCI score as dependent variable and adjusting the model for depression, anxiety and for clinical and socio-demographic variables. We used a backward selection method to choose the final model. RESULTS: In the unadjusted analysis, fibromyalgia was associated with all personality traits, except persistency. After adjusting for depression and anxiety, patients with fibromyalgia presented decreased novelty seeking compared to controls; the differences in other personality traits were no longer significant. Novelty seeking was also correlated with the length of history of fibromyalgia and pain intensity. CONCLUSIONS: Decreased novelty seeking may be a personality trait associated with fibromyalgia. Depression and anxiety should be considered potential confounders in the evaluation of personality traits in this population.

Improvement in pain, fatigue, and subjective sleep quality through sleep hygiene tips in patients with fibromyalgia.

OBJECTIVE: To evaluate the effectiveness of sleep hygiene instructions for women with fibromyalgia. MATERIALS AND METHODS: Seventy women with fibromyalgia completed the study. The assessment comprised the Fibromyalgia Impact Questionnaire (FIQ), the Pittsburgh Sleep Quality Index (PSQI), and a general questionnaire with personal data and lifestyle information. All patients received information about the disease and a sleep diary, but only the experimental group received the sleep hygiene instructions. Patients were asked to practice sleep hygiene, and, after three months, they were reevaluated by use of the same questionnaires. RESULTS: The mean age in the control group was 55.2 ±7.12 years, and, in the experimental group, 53.5 ±8.89 years (P = 0.392). The experimental group showed: a decrease in the pain Visual Analogue Scale values (P = 0.028), in fatigue (P = 0.021), and in the PSQI component 1 (P = 0.030); and a significant reduction in the difficulty falling asleep after waking up in the middle of the night (P = 0.031). The experimental group also showed an increase in the reporting percentage of "silent environment" (ranging from 42.9% to 68.6%), a decrease in the reporting percentage of "fairly quiet environment" (ranging from 40% to 22.9%), and a decrease in the reporting percentage of "noisy environment" (ranging from 17.1% to 8.6%). These changes facilitated falling asleep after waking up in the middle of the night. CONCLUSION: The sleep hygiene instructions allowed changing the patients' behavior, which resulted in pain and fatigue improvement, increased subjective quality of sleep, in addition to facilitating falling asleep after waking up in the middle of the night.

Melhora da dor, do cansaço e da qualidade subjetiva do sono por meio de orientações de higiene do sono em pacientes com fibromialgia / Improvement in pain, fatigue, and subjective sleep quality through sleep hygiene tips in patients with fibromyalgia

OBJETIVO: Avaliar a efetividade das orientações para higiene do sono em mulheres portadoras de fibromialgia. MATERIAIS E MÉTODOS: Setenta mulheres completaram o estudo. Na avaliação foram aplicados o Questionário de Impacto da Fibromialgia(FIQ), o Índice de Qualidade do Sono de Pittsburgh (PSQI) e um questionário geral, com dados pessoais e informações de hábitos de vida. Todas as pacientes receberam informações quanto à doença, além de um diário do sono, e apenas o grupo-experimental recebeu orientações para higiene do sono. Foi solicitado às pacientes que realizassem a higiene do sono, e as mesmas foram reavaliadas após três meses. RESULTADOS: A idade média das pacientes do grupo-controle foi 55,2 ± 7,12 anos, e a do grupo-experimental foi 53,5 ± 8,89 anos (P = 0,392). Nessas pacientes foram observadas diminuições da medida de Escala Visual Analógica de dor (P = 0,028), de cansaço (P = 0,021) e do componente 1 do PSQI (P = 0,030). O grupo que recebeu orientações para higiene do sono mostrou redução significativa na dificuldade de retorno ao sono quando acordava de madrugada (P = 0,031). O grupo-experimental apresentou aumento na porcentagem de relatos de "ambiente sem ruído" (variando de 42,9% para 68,6%), diminuição da porcentagem de relatos de "ambiente com pouco ruído" (variando de 40% para 22,9%) e diminuição na porcentagem de relatos de "ambiente com muito ruído" (variando de 17,1% para 8,6%). As alterações facilitaram o retorno ao sono quando as pacientes acordavam durante a madrugada. CONCLUSÃO: Uma cartilha com orientações de higiene do sono permitiu a alteração do comportamento das pacientes, que obtiveram melhora da dor e do cansaço, aumento da qualidade subjetiva do sono, além de facilitação do retorno ao sono após despertar durante a madrugada.

Fluctuation of anti-endothelial cell antibody titers in " mixed connective tissue disease.

BACKGROUND: Antibodies directed against endothelial cell surface antigens have been described in many disorders and have been associated with disease activity. Since the most prominent histopathologic feature in mixed connective tissue disease (MCTD) is the widespread and unique proliferative vascular lesion, our aim was to evaluate the frequency of anti-endothelial cell antibodies (AECA) in this condition. OBJECTIVES: To evaluate the frequency of AECA in this disease and assess its clinical and laboratory associations. METHODS: Seventy-three sera from 35 patients with MCTD (Kasukawa's criteria), collected during a 7 year period, were tested for immunoglobulins G and M (IgG and IgM) AECA by cellular ELISA, using HUVEC (human umbilical vein endothelial cells). Sera from 37 patients with systemic lupus erythematosus (SLE), 22 with systemic sclerosis (SSc) and 36 sera from normal healthy individuals were used as controls. A cellular ELISA using HeLa cells was also performed as a laboratory control method. RESULTS: IgG-AECA was detected in 77% of MCTD patients, 54% of SLE patients, 36% of SSc patients and 6% of normal controls. In MCTD, IgG-AECA was associated with vasculitic manifestations, disease activity and lymphopenia, and was also a predictor of constant disease activity. Immunosuppressive drugs were shown to reduce IgG-AECA titers. Since antibodies directed to HeLa cell surface were negative, AECA was apparently unrelated to common epitopes present on epithelial cell lines. CONCLUSIONS: AECA are present in a large proportion of patients with MCTD and these antibodies decrease after immunosuppressive treatment.

Anti-TNF therapy for polymyalgia rheumatica: report of 99 cases and review of the literature.

The objective of this study was to analyze the clinical, laboratorial, and therapeutical response of polymyalgia rheumatica (PMR) to anti-tumor necrosis factor (anti-TNF) treatment. We systematically searched English articles on the subjects of PMR who were treated with TNF blockers in Pubmed from 1994 to 2010. In addition, we reported on two patients with PMR who were treated by the Rheumatology Division of the Hospital das Clínicas da Faculdade de Medicina da Universidade in São Paulo, Brazil. Ninety-nine cases of patients with PMR treated with anti-TNF were reviewed. The age of these patients ranged from 63 to 84 years, and 70.7% of them were female. Disease duration varied from 10.5 weeks to 95 months, and time of follow-up varied from 2 weeks to 21 months. Infliximab was the anti-TNF of choice in three studies, while etanercept was in five. Time to response varied from 2 to 8 weeks. After anti-TNF treatment, prednisone reduction was observed in all studies. Clinical improvement was found in 7/7 studies, and laboratory improvement of at least 50% of inflammatory markers was observed in 6/7 studies. This study demonstrated a good clinical and laboratory response to anti-TNF therapy in patients with PMR, with or without glucocorticoid.

The association of major depressive episode and personality traits in patients with fibromyalgia.

INTRODUCTION: Personality traits have been associated with primary depression. However, it is not known whether this association takes place in the case of depression comorbid with fibromyalgia. OBJECTIVE: The authors investigated the association between a current major depressive episode and temperament traits (e.g., harm avoidance). METHOD: A sample of 69 adult female patients with fibromyalgia was assessed with the Temperament and Character Inventory. Psychiatric diagnoses were assessed with the Mini-International Neuropsychiatric Interview severity of depressive symptomatology with the Beck Depression Inventory, and anxiety symptomatology with the IDATE-state and pain intensity with a visual analog scale. RESULTS: A current major depressive episode was diagnosed in 28 (40.5%) of the patients. They presented higher levels of harm avoidance and lower levels of cooperativeness and self-directedness compared with non-depressed patients, which is consistent with the Temperament and Character Inventory profile of subjects with primary depression. However, in contrast to previous results in primary depression, no association between a major depressive episode and self-transcendence was found. CONCLUSIONS: The results highlight specific features of depression in fibromyalgia subjects and may prove important for enhancing the diagnosis and prognosis of depression in fibromyalgia patients.

Behçet's disease associated with celiac disease: a very rare association.

There are common findings between Behçet's disease (BD) and celiac disease (CD); however, association in the same patient is a rarity. We relate the third case in the literature of this overlap in a 40-year-old woman with history of obstipation since her childhood. She also presented asymmetric polyarthralgia, loss of weight, anemia, oral recurrent aphthas (>3/year) and genital ulcerations, inflammatory lower back pain, bowel bleeding and abdominal colic. Afterwards, she presented episodes of erythema nodosum, superficial thrombophlebitis, pseudofolliculitis and aseptic meningitis, thus fulfilling criteria for BD. Due to persistence of the digestive complaints, a gastrointestinal endoscopy was performed. The biopsy showed chronic duodenitis with intraepithelial lymphocytosis, crypt hyperplasia, and villous atrophy. Endomysial antibody was positive. She fulfilled the diagnosis criteria for CD; a gluten-free diet was applied with clinical improvement. Ascertaining whether pathogenic mechanisms are common in these two conditions requires further investigation.

Faraway from the silk route: demographic and clinical features of Behçet's disease in 106 Brazilian patients.

To describe clinical and epidemiological data of Behçet's disease (BD) in Brazil, we retrospectively reviewed records of all patients seen between 2006 and 2007 at the BD outpatient clinic of University of Sao Paulo. One hundred and six patients fulfilled the International Study Group for Behçet's Disease diagnostic criteria and they were included in this study. There was a female/male ratio of 2.2:1 and mean age at diagnosis was 31.9 +/- 9.2 years. In order of frequency, oral (100%) and genital ulcerations (92.5%), pseudofolliculitis (59.4%), erythema nodosum (49.1%), ocular lesions (47.2%), and musculoskeletal complaints (35.8%) were the most common manifestations. Blindness and major vessel involvement (18.2% vs. 5.5%, p = 0.038 and 27.3% vs. 9.6%, p = 0.019) were more frequent among male than female patients. We concluded that in Brazil, a South American country faraway from the Silk Route, BD follows the same pattern exhibited on its usual endemic area.

Behçet's disease: clinical value of the video capsule endoscopy for small intestine examination.

We described a pilot study using Video capsule endoscopy (VCE) aiming the assessment of small bowel in Behçet's disease (BD). Ten patients with BD and abdominal complaints underwent VCE with Given Pillcam SB (Given Imaging Ltd., Yoqneam). VCE revealed small bowel lesions in all ten subjects. Five patients had active symptoms of BD while five others had clinically inactive disease. Jejune was the most frequently affected GI segment being involved in eight cases, four from each group. We suggest that small bowel involvement may be frequent in BD patients, even in the absence of oral ulcerations.

Pain in fibromyalgia and discrimination power of the instruments: Visual Analog Scale, Dolorimetry and the McGill Pain Questionnaire.

OBJECTIVE: The aim of this study was to verify the discriminative power of the most widely used pain assessment instruments. METHODS: The sample consisted of 279 subjects divided into Fibromyalgia Group FM- 205 patients with fibromyalgia and Control Group CG-74 healthy subjects), mean age 49.29 +/- 10.76 years. Only 9 subjects were male, 6 in FM and 3 in CG. FM were outpatients from the Rheumatology Clinic of the University of São Paulo--Hospital das Clínicas (HCFMUSP); the CG included people accompanying patients and hospital staff with similar socio-demographic characteristics. Three instruments were used to assess pain: the McGill Pain Questionnaire MPQ, the Visual Analog Scale (VAS), and the Dolorimetry, to measure pain threshold on tender points (generating the TP index). In order to assess the discriminative power of the instruments the measurements obtained were submitted to descriptive analysis and inferential analysis using ROC Curve-sensibility (S), specificity (S1) and area under the curve (AUC)--and Contingence tables with Chi-square Test and odds ratio. Significance level was 0.05. RESULTS: Higher sensibility specificity and area under the curve was obtained by VAS (80% 80% and 0.864, respectively), followed by Dolorimetry (S 77% S177% and AUC 0.851), McGill Sensory (S 72% S167% and AUC 0.765) and McGill Affective (S 69% S1 67% and AUC 0.753). CONCLUSIONS: VAS presented the higher sensibility, specificity and AUC, showing the greatest discriminative power among the instruments. However, these values are considerably similar to those of Dolorimetry.

Anti-endothelial cell antibodies and central nervous system involvement in Behçet's disease.

INTRODUCTION: Previous studies have detected the presence of anti-endothelial cell antibodies (AECA) in patients with Behçet's disease (BD). However, no real evidence exists whether these antibodies exert any influence on clinical presentation and/or activity of this disease. OBJECTIVES: To determine the frequency of AECA in patients with BD and analyze possible clinical associations. METHODS: 50 patients with BD who fulfilled diagnostic criteria were selected. Thirty-seven patients were females, and 13 were males; the mean age was 44 +/- 9 years with a mean follow-up time of 10 +/- 7.5 years. AECA were assayed by ELISA using ECV-304 cells as the antigenic substrate. The prevalence of AECA was determined, and their possible relationships with present and past clinical features were investigated. RESULTS: AECA were detected in the sera of 38% of the patients (IgG in 13, IgM in four, and IgG plus IgM in two). An association was observed between AECA and a previous history of central nervous system involvement (OR= 5.4, p= 0.03). This association was more evident for IgG-AECA (OR= 6.0, p= 0.02). A trend of an increased risk of aneurysms was also observed in patients with IgG-AECA (OR= 2.58, p= 0.77). None of the other clinical characteristics showed a relevant association with these antibodies. CONCLUSION: Our data suggest that IgG-AECA may be a marker of more severe lesions in patients with BD based on the higher frequency of previous central nervous system manifestations in patients who presently display circulating AECA.

Effects of yoga and the addition of Tui Na in patients with fibromyalgia.

OBJECTIVES: This study aimed to verify whether techniques of yoga with and without the addition of Tui Na might improve pain and the negative impact of fibromyalgia (FMS) on patients' daily life. DESIGN: Forty (40) FMS women were randomized into two groups, Relaxing Yoga (RY) and Relaxing Yoga plus Touch (RYT), for eight weekly sessions of stretching, breathing, and relaxing yogic techniques. RYT patients were further submitted to manipulative techniques of Tui Na. OUTCOME MEASURE: Outcome measures comprised the Fibromyalgia Impact Questionnaire (FIQ), pain threshold at the 18 FMS tender points, and a verbal graduation of pain assessed before treatment and on the followup. The visual analog scale (VAS) for pain was assessed before and after each session and on the follow-up. RESULTS: Seventeen (17) RYT and 16 RY patients completed the study. Both RY and RYT groups showed improvement in the FIQ and VAS scores, which decreased on all sessions. The RYT group showed lower VAS and verbal scores for pain on the eighth session, but this difference was not maintained on the follow-up. Conversely, RY VAS and verbal scores were significantly lower just on the follow-up. CONCLUSIONS: These study results showed that yogic techniques are valid therapeutic methods for FMS. Touch addition yielded greater improvement during the treatment. Over time, however, RY patients reported less pain than RYT. These results suggest that a passive therapy may possibly decrease control over FMS symptoms.

INTRODUÇÃO: Estudos anteriores detectaram a presence de anticorpos anti-célula endotelial (AACE) em pacientes com doença de Behçet, porém não há nenhuma evidência se a presença destes anticorpos exerce alguma influência na apresentação clínica ou atividade da doença. OBJETIVOS: Determinar a freqüência de AACE em pacientes com doença de Behçet e analisar possíveis associações clínicas. MÉTODOS: Foram selecionados 50 pacientes que preencheram corretamente os critérios diagnósticos para a doença de Behçet. Trinta e sete pacientes eram do sexo feminino e 13 do sexo masculino, média de idade de 44 ± 9 anos e tempo médio de seguimento de 10 ± 7,5 anos. O AACE foram analisados por ELISA utilizando células ECV-304 como substrato antigênico. A prevalência de AACE foi determinada e foram investigadas possíveis relações com características clínicas atuais e pregressas. RESULTADOS: Os AACE foram detectados no soro de 38 por cento dos pacientes (13 na forma IgG, 4 IgM e 2 nas formas IgG e IgM). Observamos uma associação entre o AACE e história pregressa de envolvimento de sistema nervoso central (OR=5,4; p=0,03). Esta associação era mais evidente para o AACE na forma IgG (OR=6,0; p=0,02). Observamos também uma tendência de risco aumentado de aneurismas em pacientes com AACE na forma IgG (OR=2,58; p=0,77). Nenhuma outra característica clínica mostrou-se relevante com o anticorpo estudado. CONCLUSÃO: Nossos dados sugerem que o AACE na forma IgG pode ser uma marcador de lesão mais grave em pacientes com doença de Behçet baseado no fato de encontrarmos uma maior freqüência de história pregressa de manifestação de sistema nervoso central em pacientes com AACE circulante.

Auto-eficácia e sintomas depressivos em doentes com dor crônica / Self-efficacy and depressive symptoms in chronic pain patients

CONTEXTO: Auto-eficácia é a crença na habilidade pessoal de desempenhar com sucesso tarefas ou de apresentar comportamentos para produzir um resultado desejável. É conceito-chave para o adequado controle de doenças crônicas e estudos sobre o tema são incipientes no Brasil. OBJETIVO: Avaliar a crença de auto-eficácia de pacientes com dor crônica e relacioná-la a variáveis sociodemográficas, de características da dor e à presença de sintomas depressivos. MÉTODOS: A amostra, de conveniência, foi de 132 sujeitos. Os instrumentos utilizados foram a Escala de Auto-Eficácia para Dor Crônica (AEDC) e o Inventário de Depressão de Beck (IDB). RESULTADOS: O escore médio de auto-eficácia foi 170,8 (DP = 56,7). Auto-eficácia menor foi observada nos pacientes com até 8 anos de escolaridade, quando comparada à de pacientes com escolaridade entre 9 e 11 anos (p = 0,015). Auto-eficácia mais elevada foi observada nos doentes com dor menos intensa (p = 0,042). A Escala AEDC apresentou correlação negativa com o IDB (r = - 0,48; p < 0,01). CONCLUSÕES: Os doentes com escolaridade de até 8 anos apresentaram auto-eficácia menor que os doentes que tinham entre 9 e 11 anos de escolaridade. Os pacientes com dor menos intensa e os doentes com menos sintomas depressivos apresentaram maior auto-eficácia.

BACKGROUND: Self-efficacy is the belief about oneÆs personal ability to perform a task or specific behavior successfully. Self-efficacy is a key concept to manage chronic diseases and the studies about it are insufficient in Brazil. OBJECTIVE: To evaluate chronic pain patientÆs self-efficacy belief and relate to social demographic variables, pain and depressive symptoms. METHODS: The convenience sample was 132 subjects. The instruments utilized were Chronic Pain Self-efficacy Scale (CPSS) in Portuguese version (AEDC) and Beck Depression Inventory (BDI). RESULTS: The self-efficacy average score was 170.8 (DP = 56.7). Low self-efficacy was observed in 8 year education level patients compared to 9 to 11 year education level (p = 0.015). Higher self-efficacy was observed in patients with lower pain intensity (p = 0.042). The AEDC was negative correlated to IDB depression (r = - 0.48; p < 0.01). CONCLUSIONS: Patients with 8 year education level showed low self-efficacy than patients with 9 to 11 year education level. Subjects with lower pain intensity and fewer depressive symptoms showed higher self-efficacy scores.

Sleep quality in patients with fibromyalgia using the Pittsburgh Sleep Quality Index.

OBJECTIVE: To characterize and quantify the sleep complaints of patients with fibromyalgia (FM) using the Pittsburgh Sleep Quality Index (PSQI). METHODS: The PSQI was applied to 30 patients with FM according to American College of Rheumatology classification criteria and to 30 healthy controls in individual sessions under similar conditions. RESULTS: The median global PSQI scores were [median (25-75%)] 12.0 (10-16) and 3.0 (2.0-5.0) in patients with FM and controls, respectively (p < 0.001). All PSQI component scores except sleep medications were significantly higher in patients than controls. Sleep latency, sleep disturbances, and daytime dysfunction were the most frequent sleep difficulties experienced by patients with FM. CONCLUSION: Our results indicate that the PSQI is a useful instrument for characterizing and quantifying sleep disturbances in patients with FM.
