RESUMEN
Autoimmune and autoinflammatory diseases are associated with severe morbidity, and represent an impactful health and economic burden worldwide. The treatment of these diseases can include a course with detrimental side effects. Immunosuppression increases the risk of opportunistic infections, but in some cases, the abrupt discontinuation of these medications can result in immune reconstitution inflammatory syndrome. Special attention must be directed to endemic tropical infections, such as leishmaniasis, Chagas disease, malaria, arbovirosis, yellow fever, leprosy, paracoccidioidomycosis, disseminated strongyloidiasis, and ectoparasitosis. These endemic diseases of developing countries can be considered as possible emerging diseases in developed regions partially because of environmental factors and migration. In the present article, we aim to review the evidence-based aspects of the most important opportunistic tropical infections in immunosuppressed patients. We also aim to review the important aspects of vaccination, chemical prophylaxis, and treatment for these infections in people with medication-induced immunosuppression.

Background: Systemic lupus erythematosus (SLE) is a potentially fatal complex autoimmune disease, that is characterized by widespread inflammation manifesting tissue damage and comorbidities across the human body including heart, blood vessels, joints, skin, liver, kidneys, and periodontal tissues. The etiology of SLE is partially attributed to a deregulated inflammatory response to microbial dysbiosis and environmental changes. In the mouth, periodontal environment provides an optimal niche for local and systemic inflammation. Our aim was to evaluate the reciprocal impact of periodontal subgingival microbiome on SLE systemic inflammation. Methods: Ninety-one female subjects were recruited, including healthy (n = 31), SLE-inactive (n = 29), and SLE-active (n = 31). Patients were screened for probing depth, bleeding on probing, clinical attachment level, and classified according to CDC/AAP criteria with or without periodontal dysbiosis. Serum inflammatory cytokines were measured by human cytokine panel and a targeted pathogenic subgingival biofilm panel was examined by DNA-DNA checkerboard from subgingival plaque samples. Results: The results showed significant upregulation of serum proinflammatory cytokines in individuals with SLE when compared to controls. Stratification of subject's into SLE-inactive (I) and SLE-active (A) phenotypes or periodontitis and non-periodontitis groups provided new insights into SLE pathophysiology. Ten proinflammatory cytokines were upregulated in serum of SLE-I only and one in SLE-A only. Four molecules overlapped in SLE-A and SLE-I. Anti-inflammatory cytokines included IL-4 IL-10, which were upregulated in SLE-I sera (but not SLE-A), controlling clinical phenotypes. Out of 24 significant differential oral microbial abundances found in SLE, 14 unique subgingival bacteria profiles were found to be elevated in SLE. The most severe oral pathogens (Treponema denticola and Tannerella forsythia) showed increase abundances on SLE-A periodontal sites when compared to SLE-I and healthy controls. Inflammation as measured by cytokine-microbial correlations showed that periodontal pathogens dominating the environment increased proinflammatory cytokines systemically. Conclusions: Altogether, low-grade systemic inflammation that influenced SLE disease activity and severity was correlated to dysbiotic changes of the oral microbiota present in periodontal diseases.

INTRODUÇÃO: A polifarmácia pode ser classificada como quantitativa e qualitativa. Entre os conceitos para a quantitativa, está a utilização de dois ou mais medicamentos. Por sua vez, a polifarmácia qualitativa considera a racionalização da terapia farmacológica. OBJETIVOS: Com base nos dois conceitos apresentados, este estudo objetivou avaliar a prevalência da polifarmácia em idosos com demência e correlacioná-la às características socioclínicas, demográficas e farmacológicas. MÉTODOS: Foi realizado um estudo transversal em um centro de referência em demência no Distrito Federal, incluindo 97 idosos com diagnóstico de demência de Alzheimer. Foram identificadas as prevalências da polifarmácia quantitativa e da qualitativa, e, valendo-se da análise univariada, correlacionou-se a presença de polifarmácia às características da população. A estatística descritiva foi calculada para todas as variáveis, as dependentes e as independentes. A correlação entre as variáveis secundárias e a polifarmácia foi determinada pela razão de prevalências. Para a análise univariada, utilizaram-se os seguintes testes estatísticos: χ2 de Pearson, Kruskal-Wallis e Wilcoxon-Mann-Whitney (WMW). RESULTADOS: A prevalência da polifarmácia quantitativa foi de 92,8%, sendo 37,2% leve, 25,8% moderada e 29,8% grave, e a da qualitativa foi de 49,5%. Analisando-se os dados, as características socioclínicas e demográficas não estiveram associadas nem com a polifarmácia quantitativa nem com a qualitativa. CONCLUSÃO: A polifarmácia quantitativa e a qualitativa foram prevalentes entre os idosos com demência. O atendimento ambulatorial multiprofissional aos idosos mediante a metodologia de identificação e qualificação das polifarmácias quantitativa e qualitativa parece ser uma ferramenta útil para promover o uso racional de medicamentos
BACKGROUND: Polypharmacy can be defined quantitatively or qualitatively. One of the concepts underlying the quantitative definition of polypharmacy is the use of two or more medications. The qualitative definition, in turn, takes into account the rationalization of pharmacotherapy. OBJECTIVES: Based on these two concepts, this study aimed to determine the prevalence of polypharmacy in older adults with dementia and correlate it with sociodemographic, clinical, and pharmacological characteristics. METHODS: A cross-sectional study was conducted in a center of excellence for dementia care in the Federal District, including 97 older adults with a diagnosis of Alzheimer dementia. Prevalence rates were determined for quantitative and qualitative polypharmacy. The presence of polypharmacy was correlated with the characteristics of the sample by univariate analysis. Descriptive statistics were calculated for all dependent and independent variables. The correlation between secondary variables and polypharmacy was determined by prevalence ratio. Univariate analysis was performed using the following statistical tests: Pearson's χ2 test, Kruskal-Wallis test, and Wilcoxon-Mann-Whitney (WMW) test. RESULTS: The prevalence of quantitative polypharmacy was 92.8%, of which 37.2% were characterized as minor, 25.8% as moderate, and 29.8% as major. The prevalence of qualitative polypharmacy was 49.5%. Sociodemographic and clinical characteristics were not associated with quantitative or qualitative polypharmacy. CONCLUSION: Both quantitative and qualitative polypharmacy were highly prevalent among older adults with dementia. The delivery of multidisciplinary care to older outpatients through a methodology that identifies and characterizes polypharmacy both quantitatively and qualitatively seems to be a useful tool to promote the rational use of medications

Lupus Eritematoso SistémicoRESUMEN
BACKGROUND: Fibromyalgia is a common chronic disease characterized by persistent diffuse pain, fatigue, sleep disorders and functional symptoms. The disease can have negative consequences in personal and social life, in addition to significant public health expenses caused by treatment and work leave. The purpose of this article is to evaluate the number of social security benefits granted due to incapacity for work in Brazil in patients with ICD M79 and variants in the period 2006-2015. There has been no previous study with data referring to work withdrawals caused by fibromyalgia in Brazil. METHODS: Data for this study were obtained through an official Social Security platform. The disability and retirement benefits were analyzed. RESULTS: A total of 95,882 social security disability benefits were granted to ICD M79 and variants in the period from 2006 to 2015. Regarding gender, 69,420 benefits (72.3%) were granted to women and 26,562 (27.7%) to men. Regarding the types of benefits, we found 93,556 (97.5%) temporary withdrawals from work and 2426 (2.5%) permanent withdrawals. When comparing the initial and final years, we observed a significant reduction in the number of awards: 15,562 in 2006 to 6163 in 2015. CONCLUSION: Fibromyalgia was an important cause of withdrawal due to incapacity for work in Brazil, with consequent public health expenditure. These data may serve as a basis for new studies and can alert professionals of the need for adequate management of fibromyalgia to reduce work withdrawal and its consequences.

Abstract Objective To describe the characteristics and progression of the supply of new rheumatologists in Brazil, from 2000 to 2015. Methods: Consultations to databases and official documents of institutions related to training and certification of rheumatologists in Brazil took place. The data were compared, summarized and presented descriptively. Results: From 2000 to 2015, Brazil qualified 1091 physicians as rheumatologists, of which 76.9% (n = 839) completed a medical residency program in rheumatology (MRPR); the others (n = 252) achieved this title without MRPR training. There was an expansion of MRPR positions. At the same time, there was a change in the profile of the newly qualified doctors. Early in the series, the fraction of new rheumatologists without MRPR, entering the market annually, was approaching 50%, dropping to about 15% in recent years. In 2015, Brazil offered 49 MRPR accredited programs, with 120 positions per year for access. There was an imbalance in the distribution of MRPR positions across the country, with a strong concentration in the southeast region, which in 2015 held 59.2% of the positions. Public institutions accounted for 94% (n = 789) of graduates in MRPR during the study period, while still maintaining 93.3% (n = 112) of seats for admission in 2015. Conclusions: In the last sixteen years, in parallel with the expansion of places of access, MRPR has established itself as the preferred route for rheumatology training in Brazil, mainly supported by public funds. Regional inequalities in the provision of MRPR positions still persist, as challenges that must be faced.
Resumo Objetivo: Descrever as características e a evolução da oferta de novos reumatologistas no Brasil, de 2000 a 2015. Métodos: Fizeram-se consultas a bases de dados e a documentos oficiais de instituições relacionadas à formação e à certificação de reumatologistas no país. Os dados foram cruzados, sumarizados e apresentados de forma descritiva. Resultados: De 2000 até 2015, o Brasil habilitou 1.091 médicos à condição de reumatologistas, dentre os quais 76,9% (n = 839) concluíram residência médica em reumatologia (RMR); os demais (n = 252) obtiveram o título sem cursar RMR. Houve expansão das vagas de RMR. Paralelamente, ocorreu uma modificação no perfil dos recém-habilitados. No início da série, a fração de novos reumatologistas sem RMR, ingressantes no mercado anualmente, aproximava-se dos 50%, reduziu-se para cerca de 15%, em anos recentes. Em 2015, havia no país 49 programas de RMR credenciados, com 120 vagas anuais de acesso. Observou-se desequilíbrio na distribuição de vagas de RMR pelo país, com forte concentração na Região Sudeste, que em 2015 detinha 59,2% das vagas. Instituições públicas responderam por 94% (n = 789) dos concluintes de RMR no período estudado, mantiveram ainda 93,3% (n = 112) das vagas para ingresso em 2015. Conclusões: Nos últimos 16 anos, paralelamente à expansão das vagas de acesso, a RMR consolidou-se como via preferencial para formação em reumatologia no Brasil, eminentemente suportada por recursos públicos. Desigualdades regionais na oferta de vagas de RMR persistem como desafios a serem enfrentados.

OBJECTIVES: To investigate the association between baseline serum levels of 25-hydroxyvitamin D (25(OH)D) and gait pattern in patients undergoing total hip arthroplasty (THA). METHODS: Prospective study of patients with hip osteoarthritis undergoing primary THA between January 2012 and December 2013. Blood samples were collected on the day of hospital admission. Gait analyses were performed before surgery and 3 months postoperatively. Internal moments were captured. RESULTS: Major improvements were observed in gait data after THA. 25(OH)D levels correlated with change in peak extension (R=0.25, p=0.017) and peak power generation (R=0.25, p=0.04). Multiple linear regression analyses were performed. In model 1, 25(OH)D and change in gait speed explained the variability of peak extension (R2=0.1, p=0.004). In model 2, only 25(OH)D explained the variability of peak power generation (R2=0.05, p=0.044). CONCLUSIONS: 25(OH)D levels were correlated with change in peak extension and peak power generation. The effect of 25(OH)D on change in gait variables after THA is modest.

The physician Charles-Édouard Brown-Séquard was a neurologist of considerable importance. In 1846 his thesis 'Researches and Experiments on the Physiology of the Spinal Cord' brought out knowledge about the sensory pathways which remains until today. The Emperor, Dom Pedro II was the second and last Emperor of Brazil, reigning for 49 years and remembered for defending the nation's integrity, the end of slavery, support for education and culture, diplomacy and relations with international personalities. He married Dona Teresa Cristina of Bourbon-Two Sicilies (1822-1889) by proxy in 1843, the fourth and last Empress consort of Brazil. This paper reports the exchange of letters between these personalities of the XIX century. Although they lived far from each other and worked in areas so different, they discussed the health of the Empress in letters. Dom Pedro II made contact with Brown-Séquard hoping that ' your knowledge shall help heal my wife of nervous disease . ' According to Dom Pedro the Empress suffered ' for a long time with more or less long interruptions of horrible neuralgic pains in the legs, head and the scalp. Two points on the dorsal spine feel the effects more or less with pressure applied . ' In addition to describing and documenting the exchange of letters, this paper raises the possibility that the Empress suffered from the fibromyalgia syndrome.

RESUMOObjetivos:A coorte Sarar é composta por pacientes portadores de artrite reumatoide (AR) e artrite idiopática juvenil (AIJ) submetidos a artroplastias de quadril e joelho no hospital Sarah-Brasília. O objetivo deste estudo foi avaliar fatores clínicos e laboratoriais associados à atividade de doença, capacidade funcional e dano radiológico em pacientes com AR, participantes dessa coorte.Métodos:Estudo transversal, com coleta de dados em revisão de prontuário.Resultados:Foram incluídos 32 pacientes, com tempo médio de início da doença de 240 meses. Dezenove pacientes foram submetidos a ATJ e 17, a ATQ. Foi encontrada correlação positiva entre dose máxima de metotrexato (MTX) durante a evolução e Clinical Disease Activity Index (CDAI) (R = -0,46, p = 0,011) e negativa com Simplified Erosion and Narrowing Score (SENS) (R = -0,58, p = 0,004). Valores de SENS foram maiores nos pacientes com fator reumatoide (FR) (p = 0,005) e anticorpo antipeptídeo cíclico citrulinado 3 (anti-CCP3) positivo (p = 0,044), nos com maiores títulos de FR (p = 0,037) e anti-CCP3 (p = 0,025) e menores nos pacientes com história familiar de AR (p = 0,009). Valores de HAQ foram maiores em pacientes mais idosos (p = 0,031). Na regressão linear múltipla, somente “dose máxima de MTX” e “história familiar” permaneceram com associação significativa com SENS (r2= 0,73, p < 0,001 para ambas as variáveis). No modelo que avaliou CDAI, apenas “dose máxima de MTX” permaneceu com associação significativa (r2 = 0,35, p = 0,016).Conclusão:Na coorte Sarar, fatores clínicos e laboratoriais estiveram relacionados à atividade de doença, capacidade funcional e dano radiológico, semelhantemente a estudos que avaliaram pacientes com menor tempo de doença.
ABSTRACTObjectives:The Sarar cohort consists of patients with rheumatoid arthritis and juvenile idiopathic arthritis who underwent hip or knee arthroplasties at hospital SARAH-Brasília. The objective of this study was to evaluate clinical and laboratory factors associated with disease activity, functional capacity and radiological damage in rheumatoid arthritis patients, participants in this cohort.Methods:Cross-secal study, with data collection achieved from medical records review.Results:Thirty-two patients were included, with a mean time of disease onset of 240 months. Nineteen patients underwent total knee and 17 total hip arthroplasty. There was a positive correlation between maximum dose of methotrexate and Clinical Disease Activity Index (R = −0.46, p = 0.011), and a negative one with Simplified Erosion and Narrowing Score (R = −0.58, p= 0.004). Simplified Erosion and Narrowing Score values were higher in patients with rheumatoid factor (p = 0.005) and anti-cyclic citrullinated peptide antibody 3 positivity (p = 0.044), in those with higher rheumatoid factor (p = 0.037) and anti-cyclic citrullinated peptide antibody 3 (p = 0.025) titers, and lower in patients with family history of rheumatoid factor (p = 0.009). Health Assessment Questionnaire values were higher in older patients (p = 0.031). In multiple linear regression, only “maximum dose of methotrexate” and “family history” remained with significant association with Simplified Erosion and Narrowing Score (r2 = 0.73, p < 0.001 for both variables). In the model evaluating “Clinical Disease Activity Index” only “maximum dose of methotrexate” remained significantly associated (r2 = 0.35, p = 0.016).Conclusion:In the Sarar cohort, clinical and laboratory factors were related to disease activity, functional capacity and radiological damage, similar to studies evaluating patients with lower disease duration.

PURPOSE: The aim of this study was to evaluate the effectiveness of punctal occlusion using hypromellose 2% in patients with dry eye. METHODS: In this prospective, randomized single-blinded clinical trial, we evaluated 76 eyes of 38 patients (36 women and 2 men) with dry eye secondary to rheumatic diseases. In each patient, the lower lacrimal punctum of 1 eye was occluded using hypromellose 2%, whereas the contralateral eye underwent a simulation of the procedure (control group). Patients' eyes were assessed for burning, itching, redness, foreign body sensation, and tearing based on a visual scale questionnaire (score, 0-10). We also performed objective tests for evaluation of dry eye using a Schirmer test with anesthesia (basal tear secretion test), the tear film break-up time test, and fluorescein and rose bengal staining tests at 0, 28, and 56 days after treatment. RESULTS: Fluorescein and rose bengal staining tests showed that there was a significant reduction in signs after occlusion using hypromellose. The symptoms measured by the visual scale were significantly reduced. The values of the Schirmer test with anesthesia and the break-up time test increased significantly. The effects persisted for up to 8 weeks. There were no dropouts or reported side effects during the 24-month follow-up. CONCLUSIONS: Our results suggest that punctal occlusion using hypromellose 2% is a low-cost and safe additional treatment for dry eye.

Yellow fever is an infectious disease, endemic in South America and Africa. This is a potentially serious illness, with lethality between 5 and 40% of cases. The most effective preventive vaccine is constituted by the attenuated virus strain 17D, developed in 1937. It is considered safe and effective, conferring protection in more than 90% in 10 years. Adverse effects are known as mild reactions (allergies, transaminases transient elevation, fever, headache) and severe (visceral and neurotropic disease related to vaccine). However, little is known about its potential to induce autoimmune responses. This systematic review aims to identify the occurrence of autoinflammatory diseases related to 17D vaccine administration. Six studies were identified describing 13 possible cases. The diseases were Guillain-Barré syndrome, multiple sclerosis, multiple points evanescent syndrome, acute disseminated encephalomyelitis, autoimmune hepatitis, and Kawasaki disease. The data suggest that 17D vaccination may play a role in the mechanism of loss of self-tolerance.
RESUMEN
We aimed to investigate the influence of haptoglobin (Hp) and myeloperoxidase (MPO - G463A; dbSNP rs2333227) gene polymorphisms on 78 sickle cell patients of a public hospital in the Federal District/Brazil with and without iron overload, to evaluate a possible association between these polymorphisms and clinical variability, response to treatment and prognosis. Data were obtained through laboratory tests, questionnaires, research in medical records and analyses of polymorphisms using PCR-based methods. Positive correlations were found between Hp and ferritin levels, hydroxyurea treatment, hospitalisation for and sequelae from stroke; and between MPO and number of hospitalizations in the past 12 months and splenectomy. Significant associations of specific Hp genotypes with comorbidities were also found, while results suggested that MPO AA homozygosis could increase effects of asplenia. Deviation from Hardy-Weinberg equilibrium, compatible with heterozygous deficit, was observed for Hp polymorphism. Odds ratio suggested the possibility that increased chance of hospitalisation for stroke (OR = 6.346; IC 95% = 1.56-25.79; p = 0.005) and sequelae of stroke (OR = 6.556; IC 95% = 1.578-27.237; p = 0.005) could be associated with lower frequency of 1S-2 than expected. In the interaction analyses, significant effects between subjects were shown only in the group without overload for Hp polymorphism in hs-CRP levels (p = 0.000) and number of transfusions (p = 0.018), and for MPO polymorphism (p = 0.000) and the interaction Hp/MPO (p = 0.000) in hs-CRP values. Results corroborate others indicating biological differences between Hp*1 alleles and highlight the importance of this study in understanding the biological significance of Hp and MPO polymorphisms in clinical variability and response to treatment of sickle cell patients.

Patients with rheumatic diseases are more susceptible to infection, due to the underlying disease itself or to its treatment. The rheumatologist should prevent infections in those patients, vaccination being one preventive measure to be adopted. Yellow fever is one of such infectious diseases that can be avoided.The yellow fever vaccine is safe and effective for the general population, but, being an attenuated live virus vaccine, it should be avoided whenever possible in rheumatic patients on immunosuppressive drugs. Considering that yellow fever is endemic in a large area of Brazil, and that vaccination against that disease is indicated for those living in such area or travelling there, rheumatologists need to know that disease, as well as the indications for the yellow fever vaccine and contraindications to it. Our paper was aimed at highlighting the major aspects rheumatologists need to know about the yellow fever vaccine to decide about its indication or contraindication in specific situations.

OBJECTIVE: To assess the prevalence of sexual dysfunction in women followed up at the Rheumatology Outpatient Clinic of the Hospital Universitário de Brasília and of the Hospital das Clínicas da Universidade de São Paulo with the following rheumatic diseases: systemic lupus erythematosus; rheumatoid arthritis; systemic sclerosis; antiphospholipid antibody syndrome; and fibromyalgia. METHODS: The Female Sexual Function Index (FSfi), obtained by applying a 19-item questionnaire that assesses six domains (sexual desire, arousal, vaginal lubrication, orgasm, sexual satisfaction and pain), was used. RESULTS: This study assessed 163 patients. The mean age was 40.4 years. The prevalence of sexual dysfunction was 18.4%, but 24.2% of the patients reported no sexual activity over the past 4 weeks. Patients with fibromyalgia and systemic sclerosis had the highest sexual dysfunction index (33%). Excluding patients with no sexual activity, the sexual dysfunction rate reaches 24.2%. CONCLUSION: The prevalence of sexual dysfunction found in this study was lower than that reported in the literature. However, 24.2% of the patients interviewed reported no sexual activity over the past 4 weeks, which might have contributed to the low sexual dysfunction index found.

OBJECTIVE: To assess the association between quality of life and distance walked in the 6-minute walk test (6MWT) in Brazilian premenopausal patients with systemic lupus erythematosus (SLE) and compare their results with those of healthy controls. METHODS: Twenty-five premenopausal (18-45 years) patients diagnosed with low-activity SLE (mean SLEDAI: 1.52 ± 1.61) and 25 controls were matched for age, physical characteristics, and physical activity level (International Physical Activity Questionnaire/s-IPAQ). Both groups should not be involved in regular physical activity for at least six months before the study. The 6MWT distance (American Thoracic Society protocol), posttest heart rate (HRpost), posttest oxygen saturation (SpO2post) and the Borg scale of subjective perception of effort (SPE/CR10) were evaluated. The quality of life was assessed by use of the Short Form Health Survey 36 (SF-36). RESULTS: Patients with SLE had a significantly poorer quality of life, a shorter 6MWT distance (598 ± 45 m versus 642 ± 14 m, P < 0.001), and greater values of SPE/CR10 (6.28 ± 2.0 versus 5.12 ± 1.60, P< 0.05) and HRpost (134 ± 15 bpm versus 123 ± 23 bpm, P< 0.05) when compared with controls. The linear regression model suggested that quality of life was a significant predictor of 70% of the 6MWT distance. CONCLUSION: When compared with controls, patients with SLE walked a shorter distance in the 6MWT, which was associated with poorer quality of life.

Os pacientes portadores de doenças reumáticas são mais suscetíveis à infecção, quer seja pela própria doença de base ou pelo tratamento empregado. É papel do reumatologista prevenir as infecções nesse grupo de pacientes e, dentre as estratégias empregadas, encontra-se a vacinação. No grupo das doenças infecciosas que podem ser prevenidas está a febre amarela. Sua vacina é segura e eficaz na população em geral, mas, assim como as vacinas contendo organismos vivos atenuados, deve ser evitada sempre que possível em portadores de doenças reumáticas em uso de medicamentos imunossupressores. Sendo a febre amarela endêmica em grande parte do Brasil, e estando a vacinação contra essa doença indicada para a população residente em extensa parte do território nacional (além dos viajantes para essas regiões), torna-se essencial que o reumatologista tenha conhecimento da doença, das indicações e contraindicações da vacina contra a febre amarela. Nosso artigo tem o objetivo de destacar os principais aspectos que o reumatologista precisa conhecer sobre a vacina contra a febre amarela, para decidir por sua indicação ou contraindicação após avaliação do risco-benefício em situações específicas.
Patients with rheumatic diseases are more susceptible to infection, due to the underlying disease itself or to its treatment. The rheumatologist should prevent infections in those patients, vaccination being one preventive measure to be adopted. Yellow fever is one of such infectious diseases that can be avoided.The yellow fever vaccine is safe and effective for the general population, but, being an attenuated live virus vaccine, it should be avoided whenever possible in rheumatic patients on immunosuppressive drugs. Considering that yellow fever is endemic in a large area of Brazil, and that vaccination against that disease is indicated for those living in such area or travelling there, rheumatologists need to know that disease, as well as the indications for the yellow fever vaccine and contraindications to it. Our paper was aimed at highlighting the major aspects rheumatologists need to know about the yellow fever vaccine to decide about its indication or contraindication in specific situations.

OBJETIVO: Pesquisar a prevalência de disfunção sexual em mulheres com as seguintes doenças reumáticas: lúpus eritematoso sistêmico, artrite reumatoide, esclerose sistêmica, síndrome antifosfolípide e fibromialgia acompanhados no Ambulatório de Reumatologia do Hospital Universitário de Brasília e do Hospital das Clínicas da Universidade de São Paulo. MÉTODOS: Utilizou-se o índice de função sexual feminina (Female Sexual Function Index - FSfi), questionário que contém 19 itens que avaliam 6 domínios: desejo sexual, excitação sexual, lubrificação vaginal, orgasmo, satisfação sexual e dor. RESULTADOS: Foram avaliadas 163 pacientes. A média de idade foi de 40,4 anos. A prevalência de disfunção sexual foi de 18,4%, porém 24,2% das pacientes não apresentaram atividade sexual nas últimas 4 semanas. Entre os subgrupos, as pacientes com fibromialgia e esclerose sistêmica foram as com maior índice de disfunção sexual (33%). Se excluirmos as pacientes sem atividade sexual, a taxa de disfunção sobe para 24,2%. CONCLUSÃO: A prevalência de disfunção sexual encontrada neste estudo foi menor em relação à literatura. Entretanto, 24,2% das pacientes entrevistadas negaram atividade sexual nas últimas 4 semanas, o que pode ter contribuído para o baixo índice de disfunção sexual.
