Autoantibodies to DEK oncoprotein in human inflammatory disease.

OBJECTIVE To evaluate the specificity of anti-DEK antibodies for juvenile rheumatoid arthritis (JRA). METHODS Anti-DEK autoantibodies were measured by enzyme-linked immunosorbent assay (ELISA) using affinity-purified his6-DEK fusion protein. Sera from 639 subjects (417 patients with systemic autoimmune disease, 13 with sarcoidosis, 44 with pulmonary tuberculosis, 125 with uveitis, and 6 with scleritis, and 34 healthy control subjects) were screened. Reactivity was verified by immunoblotting and immunoprecipitation studies using baculovirus-expressed human DEK. RESULTS Anti-DEK activity was found at the following frequencies: JRA 39.4% (n = 71), systemic lupus erythematosus (SLE) 25.1% (n = 216), sarcoidosis 46.2% (n = 13), rheumatoid arthritis 15.5% (n = 71), systemic sclerosis 36.0% (n = 22), polymyositis 6.2% (n = 16), and adult Stills disease 0% (n = 21). Autoantibodies also were detected in 9.1% of tuberculosis sera (n = 44), but were undetectable in sera from the 34 healthy controls. Western blot and immunoprecipitation assay results correlated well with the ELISA findings. In general, levels of anti-DEK autoantibodies were higher in SLE than in other patient subsets, including JRA. CONCLUSION Anti-DEK autoantibodies are less specific for JRA than previously believed. They are produced in association with a variety of inflammatory conditions, many of which are associated with granuloma formation and/or predominant Thl cytokine production. Anti-DEK antibodies may be a marker for a subset of autoimmunity associated with interferon-gamma production rather than a particular disease subset.

Effects of external cues on gait parameters of Parkinson's disease patients: A systematic review

OBJECTIVES A systematic review to evaluate the benefits of external cues on the gait of PD patients and their impact on the quality of life, freezing and psychomotor performance was performed. The types of cues that could lead to more significant gains were analyzed. METHODS We searched for randomized clinical trials (RCTs) and quasi-randomized clinical trial (QRCTs) that assessed the influence of different external cues on gait, freezing, quality of life and psychomotor performance. RESULTS Of 259 articles collected, seven (six RCTs and one QRCT) were included in the methodological quality criteria (two consider visual cues, two consider auditory cues, one considers verbal instructions, one considers combined cues and one considers sensory cues). All of the data regarding the methodology, interventions, population and bias were described. Cues generally led to a statistically significant improvement in the step and stride length, speed of gait, cadence and UPDRS. None of these studies assessed the quality of life, and one study analyzed freezing. CONCLUSION Our review could show that external cues are effective for improving the gait parameters and psychomotor performance of PD patients. We need more studies to verify if the impact of this type of treatment could improve the quality of life of patients with PD.

Effects of transcutaneous electrical nerve stimulation (TENS) and interferential currents (IFC) in patients with nonspecific chronic low back pain: randomized clinical trial

CONTEXT AND OBJECTIVE Transcutaneous electrical nerve stimulation (TENS) and interferential current are the most used electrotherapy methods, although there is little scientific evidence to support their use. The aim of this study was to compare the effects of TENS and interferential current among patients with nonspecific chronic low back pain. DESIGN AND SETTING Single-blind randomized controlled trial in the Department of Physiotherapy, Centro Universitário de Maringá. METHODS One hundred and fifty patients were randomly divided into three groups: TENS (group 1), interferential current (group 2) and controls (group 3). The patients designated for electrotherapy received ten 30-minute sessions, while the control group remained untreated. All patients and controls were evaluated before and after treatment using a visual analog scale and the McGill Pain and Roland Morris questionnaires, and regarding their use of additional medications. RESULTS There was a mean reduction on the visual analog scale of 39.18 mm with TENS, 44.86 mm with interferential current and 8.53 mm among the controls. In the Roland Morris questionnaire, group 1 had a mean reduction of 6.59; group 2, 7.20; and group 3, 0.70 points. In group 1, 84% of the patients stopped using medications after the treatment; in group 2, 75%; and in group 3, 34%. There was no statistically significant difference between the TENS and interferential current groups (P > 0.05); a difference was only found between these groups and the controls (P < 0.0001). CONCLUSION There was no difference between TENS and interferential current for chronic low back pain treatment. CLINICAL TRIAL REGISTRATION NCT01017913.

Relação entre incontinência urinária em mulheres atletas corredoras de longa distância e distúrbio alimentar

BACKGROUND: To determine the prevalence of urinary incontinence in female long-distance runners and to compare it with the presence or not of eating disorders. Methods - A total of 37 women have completed the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and the short version of the Eating Attitudes Test (EAT-26). A one-hour pad test was performed to determine urine loss. Mean values of continuous variables were compared using an independent sample t-test or the Mann-Whitney U test. RESULTS: 23 athletes (62.2%) reported urine loss. The mean of the ICIQ-SF was 4.03 ± 5.06. There was a significant relation between the 1-hour pad test (p=0.02) and eating disorders (p=0.03). CONCLUSIONS: There was urinary incontinence in female long-distance runners and a correlation with eating disorders. Coaches should improve their knowledge about this problem and establish cooperation with a multidisciplinary team.

Bilateral deep keratitis caused by systemic lupus erythematosus

We report the optical and ultrasonic biomicroscopy and confocal microscopy findings in bilateral stromal keratitis (keratoendotheliitis), a rare ocular manifestation of systemic lupus erythematosus (SLE). Examination revealed deposits with polyrefringent crystals. Topical corticosteroid produced regression of the corneal edema, but there was an increase in corneal opacity. Ultrasound biomicroscopy images confirmed the deep location of the corneal opacities, and confocal microscopy showed a disruption of the corneal stroma and crystal-like bodies.

Influence of geolocation and ethnicity on the phenotypic expression of primary Sjögren's syndrome at diagnosis in 8310 patients : a cross-sectional study from the Big Data Sjögren Project Consortium

Objectives To analyse the influence of geolocation and ethnicity on the clinical presentation of primary Sjögrens syndrome (SjS) at diagnosis. Methods The Big Data Sjögren Project Consortium is an international, multicentre registry designed in 2014. By January 2016, 20 centres from five continents were participating. Multivariable logistic regression analyses were performed. Results We included 7748 women (93%) and 562 men (7%), with a mean age at diagnosis of primary SjS of 53 years. Ethnicity data were available for 7884 patients (95%): 6174 patients (78%) were white, 1066 patients (14%) were Asian, 393 patients (5%) were Hispanic, 104 patients (1%) were black/African-American and 147 patients (2%) were of other ethnicities. SjS was diagnosed a mean of 7 years earlier in black/African-American compared with white patients; the female-to-male ratio was highest in Asian patients (27:1) and lowest in black/African-American patients (7:1); the prevalence of sicca symptoms was lowest in Asian patients; a higher frequency of positive salivary biopsy was found in Hispanic and white patients. A north-south gradient was found with respect to a lower frequency of ocular involvement in northern countries for dry eyes and abnormal ocular tests in Europe (OR 0.46 and 0.44, respectively) and Asia (OR 0.18 and 0.49, respectively) compared with southern countries. Higher frequencies of antinuclear antibodies (ANAs) were reported in northern countries in America (OR=1.48) and Asia (OR=3.80) while, in Europe, northern countries had lowest frequencies of ANAs (OR=0.67) and Ro/La (OR=0.69). Conclusions This study provides the first evidence of a strong influence of geolocation and ethnicity on the phenotype of primary SjS at diagnosis.

Is neuromuscular electrical stimulation effective for improving pain, function and activities of daily living of knee osteoarthritis patients? A randomized clinical trial

CONTEXT AND OBJECTIVE Neuromuscular electrical stimulation (NMES) has been used in rehabilitation protocols for patients suffering from muscle weakness resulting from knee osteoarthritis. The purpose of the present study was to assess the effectiveness of an eight-week treatment program of NMES combined with exercises, for improving pain and function among patients with knee osteoarthritis. DESIGN AND SETTING Randomized clinical trial at Interlagos Specialty Ambulatory Clinic, Sao Paulo, Brazil. METHODS One hundred were randomized into two groups: NMES group and control group. The following evaluation measurements were used: numerical pain scale from 0 to 10, timed up and go (TUG) test, Lequesne index and activities of daily living (ADL) scale. RESULTS Eighty-two patients completed the study. From intention-to-treat (ITT) analysis comparing the groups, the NMES group showed a statistically significant improvement in relation to the control group, regarding pain intensity (difference between means: 1.67 [0.31 to 3.02]; P = 0.01), Lequesne index (difference between means: 1.98 [0.15 to 3.79]; P = 0.03) and ADL scale (difference between means: -11.23 [-19.88 to -2.57]; P = 0.01). CONCLUSION NMES, within a rehabilitation protocol for patients with knee osteoarthritis, is effective for improving pain, function and activities of daily living, in comparison with a group that received an orientation program.

Osteoporose - a importância da prevenção de quedas

The population growth for individuals over 60 years old has been intensified in the past thirty years in our country. This demographic change leads to epidemiological transition, characterized by the decrease of childhood death rate, reduction of infectious diseases and increase of chronic degenerate disease, such as osteoporosis. The mortality and morbidity increase due to osteoporosis has been associated with substantial economic costs attributed to hospitalization, admission to an institution, disabilities and premature deaths. Fracture is the clinical consequence of osteoporosis. Then, the evaluation of the environment at home in order to identify and remove hazards is very important as prevention strategy for falls, since they are the leading cause of more than 85% of fractures. So, it is important to remember that falls are common and considered as high morbidity events in the elderly living in communities. The challenge to the rheumatology clinician and other health professionals is the early recognition of risk factors for osteoporosis and falling; the education of patients and the intervention during the whole life, for both, men and women, is still a conduct not much developed in our community.

Biologic therapy for refractory scleritis: a new treatment perspective

Scleritis is an umbrella term for a heterogeneous group of ocular diseases that can be associated with autoimmune or systemic disorders. The purpose of this article was to review the literature regarding the use of biologic drugs to treat refractory scleritis. A search of the MEDLINE, Embase, and LILACS electronic databases was conducted, and the reference lists of published articles were hand-searched. No language filters were used. This search strategy yielded no randomized trials of the use of biologic therapies to treat scleritis; only case reports and retrospective studies were retrieved. These studies suggest that monoclonal antibodies (infliximab and adalimumab) are superior to the soluble TNF receptor fusion protein etanercept for the treatment of scleritis in patients that do not respond to corticosteroids and/or to immunosuppressive treatment. Rituximab seems to be the best option for scleritis associated with vasculitis.
