RESUMEN
The aim of this study was to determine the prevalence and incidence of Systemic Lupus Erythematosus (SLE) in Tucumán, Argentina. METHODS: The study included inpatient and outpatient charts from four public hospitals and private practice rheumatology clinics, all of them members of the Tucumán Rheumatology Society. Patients older than 16 years with diagnosis of SLE between January 2005 and December 2012 were included. Prevalence and annual incidence were calculated as the number of cases per 100.000 inhabitants during the period 2005 to 2012. RESULTS: Three hundred fifty-three patients were identified. The mean age at diagnosis was 30.5 ± 11.7 years, 93.5% women, 83% mestizos. Prevalence was 24.3 cases/100.000 inhabitants (CI 95% 22.6-28.8) and age-adjusted (≥16 years) of 34.9 cases/100.000 inhabitants (CI 95% 32.8-41.1). The annual incidence in 2005 was 1.8 cases/100.000 inhabitants (95% CI 1-2.9) and 2012 of 4.2 cases/100.000 inhabitants (95% CI 2.9-5.8). Mortality was 9.1%, with infections being the most frequent cause (14/32). CONCLUSION: The prevalence of SLE in the province of Tucumán was 34.9 cases/100.000 inhabitants.

BACKGROUND: The SpENAT, a Spanish version of the Educational Needs Assessment Tool, is a self-completed questionnaire that assesses educational needs (ENs) with the purpose of providing tailored and patient-centered information. It consists of 39 questions grouped into the 7 following domains: Pain management, Movement, Feelings, Arthritic process, Treatments, Self-help measures and Support system. OBJECTIVES: The objective of the study was to describe the ENs of rheumatoid arthritis (RA) patients using the SpENAT and to determine the main sources of information consulted by these patients. MATERIAL AND METHODS: Multicenter, observational, cross-sectional study. We included consecutive patients≥18 years with diagnosis of RA (ACR 87/ACR-EULAR 2010). Sociodemographic data, disease characteristics and clinimetric properties were recorded. All patients completed the SpENAT and were asked about the sources employed to obtain information about their disease. STATISTICAL ANALYSIS: Population characteristics were described. ENs were determined as percentages of the highest possible score for each domain. Needs for each domain according to sex, years of education, disease duration, use of biologicals and functional capacity were analyzed by means of ANOVA, and bivariate comparisons were made with Student's t-test and the Bonferroni correction. Correlation between domains was determined with the Spearman correlation coefficient. We compared patients' age by source of information with Student's t-test. RESULTS: We included 496 patients from 20 centers across the country. More ENs were observed in the domains of Movement, Feelings and the Arthritic process. Patients with higher educational level (>7 years) reported more ENs in the Arthritic process and Self-help measure domains. A higher functional impairment (HAQ-A≥0.87) was associated with more ENs in every domain. Patients with high activity showed more ENs than those in remission in the domains of Pain management, Movement, Feelings, Treatments and Support system, as well as those with low activity in Self-help measures and Support system domains. All SpENAT domains showed positive correlations among each other (P<.0001), the most important being Pain management/Movement and Treatments/Arthritic process (r≥0.7). The source of information most frequently consulted was the rheumatologist (93.95%); those who made use of Internet were on average younger (P=.0004). CONCLUSION: RA patients were very interested about knowing more about their disease. High functional impairment was associated with more ENs. Patients with high disease activity had higher EN levels in almost every domain. The rheumatologist was the main source of information for the patient with RA.

OBJECTIVE: To ascertain the prevalence of rheumatoid arthritis (RA) in Tucumán, Argentina. METHODS: The study was conducted between January 1, 1998, and December 31, 1999, in Tucumán province in northwest Argentina. Outpatient and hospitalization medical records for all patients with RA aged > or = 16 years were reviewed. Diagnosis was by 1987 American College of Rheumatology (ACR) criteria for RA and the population data were based on the 1991 national census. Prevalence rates, with 95% CI, were calculated using the number of San Miguel de Tucumán residents who fulfilled the 1987 ACR criteria for RA as numerator, and the city population aged > or = 16 as denominator. Crude and age-specific prevalence rates were calculated as number of cases/1,000 inhabitants. RESULTS: We identified 695 cases of RA. Sex-specific and overall prevalence rates (per 1,000) were 1.97 (95% CI 1.8-2) for all, 0.6 (95% CI 0.49-0.73) for men, 3.2 (95% CI 2.9-3.5) for women. CONCLUSION: Prevalence of RA is low in residents of Tucumán, Argentina, and comparable with rates observed in epidemiological surveys from Southern European countries.
