Let's Talk About Lupus. Overview of an Innovative, High-Reach, Online Program to Fill the Education Gaps of Latin Americans Living With Lupus.

BACKGROUND/OBJECTIVE: The Latin American population living with lupus lacks reliable and culturally competent health education resources. We describe a Spanish and Portuguese online program to educate Latin American people about lupus. METHODS: An extensive network of Latin American stakeholders participated in the program design, implementation, dissemination, and evaluation. Patients and rheumatologists selected core topics. Rheumatologists prepared the content using evidence-based data. Adaptations were conducted to meet the audience's health literacy and cultural values. Social media was used to post audiovisual resources and facilitate users' interactions with peers and educators, and a Web site was created to offer in-depth knowledge. RESULTS: The most massive outreach was through Facebook, with more than 20 million people reached and 80,000 followers at 3 months, between the Spanish and Portuguese pages. Nearly 90% of followers were from Latin America. A high engagement and positive responses to a satisfaction survey indicate that Facebook users valued these resources. The Spanish and Portuguese Web sites accumulated more than 62,000 page views, and 71.7% of viewers were from Latin American. CONCLUSIONS: The engagement of patients and stakeholders is critical to provide and disseminate reliable lupus education. Social media can be used to educate and facilitate interactions between people affected by lupus and qualified health care professionals. Social media-based health education has extensive and scalable outreach but is more taxing for the professional team than the Web site. However, the Web site is less likely to be used as a primary education source by Latin American people because they value social interactions when seeking lupus information.

Value of Color Doppler Ultrasound Assessment of Sacroiliac Joints in Patients with Inflammatory Low Back Pain.

OBJECTIVE: To evaluate the diagnostic value of color Doppler ultrasound (CDUS) for the detection of sacroiliitis, in patients with inflammatory back pain (IBP). METHODS: Consecutive patients with IBP and suspected axial spondyloarthritis (SpA), but without a definitive diagnosis, were included. Consecutive patients with defined SpA and axial involvement were included as a control group. All patients underwent clinical evaluation, magnetic resonance imaging (MRI), and CDUS of sacroiliac joints (SIJ) within the same week. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for the diagnosis of sacroiliitis by CDUS were calculated, using MRI as the gold standard. RESULTS: There were 198 SIJ evaluated in 99 patients (36 with previous SpA). There were 61 men (61.6%), with a mean age of 39.8 years (SD 11.3) and median disease duration of 24 months (IQR 12-84). At the patient level, CDUS had a sensitivity of 63% (95% CI 48.7-75.7%) and a specificity of 89% (95% CI 76-96%). The PPV was 87.2% (95% CI 72.6-95.7%) and the NPV was 66.7% (95% CI 53.3-78.3%). At joint level, CDUS had a sensitivity of 60% (95% CI 49-70%) and a specificity of 93% (95% CI 88-98%). The PPV was 83% (95% CI 78-95%) and the NPV was 43% (95% CI 33-56%). The sensitivity of CDUS for the diagnosis of axial SpA was 54% (95% CI 36.6-71.2%), specificity was 82% (95% CI 63.1-93.9%), PPV was 79% (95% CI 57.8-92.9%), and NPV was 59% (95% CI 42.1-74.4%). CONCLUSION: CDUS showed adequate diagnostic properties for detection of sacroiliitis and is a useful tool in patients with IBP.

Educational website incorporating rheumatoid arthritis patient needs for Latin American and Caribbean countries.

Health education is fundamental in the management of RA patients. This study explored patient needs for educational material appropriate for RA patients in our region through a website. This study includes seven focus groups and semi-structured interviews across 4 countries (Argentina, Chile, Colombia, and Mexico) with 71 RA patients. Transcripts were analyzed by anthropologists using qualitative analysis (QA), resulting in themes and subthemes to be developed. Five themes and over 50 subthemes of interest were identified by patients. Grouped into categories as follows: (1) knowing the disease, (2) living with arthritis, (3) treatment and therapies for RA, (4) psychosocial support, and (5) information for families. A response was written by the team in plain Spanish on patient subthemes of interest including additional areas that the team considered relevant. Three videos for YouTube were produced: on patient-doctor relationships, patients at work, and home and at the clinic. Illustrations in a comic book format on RA diagnosis were created. The educational site on RA of PANLAR can be found at htpp://artritisreumatoide.cl. This project accomplished a comprehensive list of RA patient interests, revealing the complex relationship between the information on the disease, the experience of a chronic disease, and the way in which patients approach, conceive, and manage their disease. We expect to gather information on how the website will be used in the future for patients and their families and maintain and improve the website as well as adapt its content to different socioeconomic realities.

Ultrasound entheseal abnormalities at the distal interphalangeal joints and clinical nail involvement in patients with psoriasis and psoriatic arthritis, supporting the nail-enthesitis theory.

OBJECTIVE: It has been shown that nail involvement in psoriasis is associated with systemic enthesopathy. Our objective was to evaluate the association of nail involvement and enthesopathy at distal interphalangeal joint (DIP) level in psoriasis (PsO) and psoriatic arthritis (PsA) patients. METHODS: Consecutive patients (54 PsO and 56 PsA) seen at the outpatients clinic in this cross-sectional study were included. All patients underwent both clinical and ultrasound (US) assessment on the same day. RESULTS: US revealed enthesopathy in at least 1 DIP joint in 9 patients with PsO (17%, 95% CI: 8-29%) and in 18 patients with PsA (32%, 95% CI: 20-46%). US extensor tendon enthesopathy was detected in a higher proportion of fingers with clinical nail involvement compared with fingers without clinical nail involvement, both in PsO and PsA patients (61.2% vs 16.8%, p < 0.0001 and 60.1% vs 22%, p < 0.0001, respectively). Among patients with PsO, 20% (95% CI: 7-41%) and 14% (95% CI: 4-32%) of those with and without clinical nail involvement showed enthesopathy on US examination, respectively (p = 0.54). Among PsA patients, the prevalence of enthesopathy was 30% (95% CI: 15-49%) for patients with clinical nail involvement and 35% (95% CI: 17-56%) for those without nail involvement (p = 0.71). CONCLUSION: Nail disease was associated with DIP US enthesopathy. There was a significant increased prevalence of extensor tendon enthesopathy in fingers with involved nails both in PsO and PsA, although no association was found between nail involvement and extensor tendon enthesopathy at patients' level. These features might support the nail-entheseal pathogenesis theory at DIP level.

Utility of Power Doppler Ultrasound-detected Synovitis for the Prediction of Short-term Flare in Psoriatic Patients with Arthritis in Clinical Remission.

OBJECTIVE: Power Doppler ultrasound (PDUS) has been shown to detect subclinical synovitis in psoriatic arthritis (PsA), but its value is not yet fully understood. The aim of this study was to evaluate PDUS features at joint level in patients with PsA in clinical remission and to investigate its value for predicting short-term flares. METHODS: Consecutive patients with PsA in clinical remission according to the attending rheumatologist and who fulfill minimal disease activity criteria and/or 28-joint Disease Activity Score in remission criteria underwent PDUS examination of 18 joints. All patients were followed up for 6 months. Disease flare was defined as any increase of disease activity generating the need of any of the following changes in therapy with disease-modifying antirheumatic drugs (DMARD) by the attending rheumatologist: dose increase, switch or addition of a different DMARD, and/or switch or addition of biological therapies. RESULTS: Among 54 patients with PsA in clinical remission, 15 (27.8%) experienced a flare within the next 6 months. Twenty patients had at least 1 joint with PDUS synovitis at baseline, and 13 (65%) of these had a disease flare during the followup period compared with only 2 of the 34 patients (5.9%) without baseline PDUS synovitis (relative risk = 11, 95% CI 2.8-44, p < 0.001). On logistic regression analysis, the only variables associated with short-term flares were baseline PDUS synovitis and the use of nonbiologic DMARD. CONCLUSION: Among patients with PsA in clinical remission, PDUS-detected synovitis was a strong predictor of short-term flare of the disease.

Patients with Psoriatic Arthritis Fulfilling the Minimal Disease Activity Criteria Do Not Have Swollen and Tender Joints, but Have Active Skin.

OBJECTIVE: To evaluate components of the minimal disease activity (MDA) criteria in psoriatic arthritis (PsA). METHODS: In patients achieving and not achieving MDA, fulfillment of each of the 7 criteria was evaluated. RESULTS: Among 41 patients with MDA, 7.4% did not fulfill the tender/swollen joint count whereas 49% did not fulfill the skin criteria. Of the 42 patients not fulfilling MDA, 100%, 76.5%, and 65% did not fulfill the patient pain score, the patient's global assessment, and the Psoriasis Area and Severity Index (PASI), respectively. CONCLUSION: A minority of patients with PsA fulfilling the MDA criteria presented active joints, but half had active skin. Visual analog scale scores and the PASI prevented patients from achieving MDA.
