RESUMO
Patients with rheumatoid arthritis (RA) or undifferentiated arthritis (UA) in the CONAART database (Argentine Consortium for Early Arthritis) were assessed for genetic risk factors for RA, specifically for HLA-DRB1 alleles and the PTPN22 rs2476601 polymorphism associated with progression to RA. This is a case-control study. Blood samples were obtained to determine HLA-DRB1 genotypes by PCR-SSO Luminex and PTPN22 (rs2476601) polymorphism by allelic discrimination. A control group of individuals from the general Argentinian population were obtained from the national register of cadaveric organ donors. A total of 1859 individuals were included in this analysis: 399 patients from the CONAART database (347 patients with RA at study end and 52 patients with UA at study end, mean follow-up time 25 ± 18 months) and 1460 individuals from the general Argentinian population. Compared with the controls, the HLA-DRB1*04 and DRB1*09 alleles were more commonly detected in patients with RA diagnosis (OR (95% CI) 2.23 (1.74-2.85) and 1.89 (1.26-2.81)) respectively. Both patients with UA and the general population showed higher frequency of DRB1*07, DRB1*11 and DRB1*15 alleles than patients with RA. PTPN22 rs2476601 polymorphism frequency was higher in RA and UA vs the general population; however, this was significantly different only for RA vs control group (OR [95% CI] = 1.81 [1.10-3.02], P = 0.018. HLA-DRB1 typing and PTPN22 allelic discrimination could distinguish between patients with UA, patients with early RA, and the general population in Argentina. This is the first study of HLA-DRB1 alleles and PTPN22 polymorphism associations with progression to early RA in an Argentinian population.

Our objective was to analyze the effects of cigarette smoking on disease activity, functional capacity, radiographic damage, serology and presence of extraarticular manifestations in patients with rheumatoid arthritis and undifferentiated arthritis. This is a cross-sectional study of 1,305 patients (729 with rheumatoid arthritis and 576 with undifferentiated arthritis) from CONAART, the Argentine Consortium for Early Arthritis that includes patients older than 16 years with <2 years of disease. Sociodemographic data, clinical characteristics of the disease and smoking history were collected. In patients with rheumatoid arthritis the disease activity score of 28 joints was 5.4 ± 1.3 in current smokers, 5.2 ± 1.4 in former smokers and 5.1 ± 1.4 in never smokers (p = 0.011). The simple erosion narrowing score was higher in current smokers and former smokers than in never smokers (M 14.0, R Q 6.0-21.0; M 15.0, R Q 7.0-24.0; M 10.0, R Q 5.0-17.0; p = 0.006). Current smokers had higher rheumatoid factor titer (M 160.0, R Q 80.0-341.0) than former smokers (M 146.8, R Q 6.03-255.5) and never smokers (M 15.0, R Q 9.0-80.0) (p = 0.004). The variable independently associated with tobacco exposure was simple erosion narrowing score (OR = 1.03, 95 % CI 1.00-1.05; p = 0.012). In patients with undifferentiated arthritis, an association between smoking status and parameters of activity or radiographic damage was not observed. Neither was tobacco exposure related to the presence of extraarticular manifestations or to the degree of disability in any of the two groups of patients. No relation was found between disease activity and severity, and number of packs smoked per year. Tobacco.

UNLABELLED: The objective of the study was to evaluate work disability and its main associated factors in patients with early arthritis. Argentine Consortium for Early Arthritis (CONAART) is the first early arthritis cohort in Argentina. Patients with one or more swollen joints and less than 2 years of symptoms duration were followed up prospectively in 13 departments of rheumatology. Social, demographic, familiar, clinical, and laboratory data were recollected. At first year and every year, X-rays of hands and feet were performed and working status and pharmaco-economic data were recollected. Work status (employed, unemployed, retired) and type of work were assessed by direct interview using a predesigned questionnaire. Eight hundred forty-eight patients were included, rheumatoid arthritis (RA) = 483 (57 %)and undifferentiated arthritis (UA) = 365 (43 %), 694 (81.8 %) were women, median age was 46 years (interquartile range (IQR) 35-55.7) and median symptoms duration 7 months (IQR 3-12). Patients with RA had significantly higher disease activity, worse functional capacity and quality of life, and more severe radiological damage compared to UA patients. However work disability (unemployed patient) was comparable between groups (RA = 21 % versus UA = 18.6 % p = NS). In both groups, unemployed patients had higher disease activity score of 28 joints (DAS28), worse Health Assessment Questionnaire (HAQ) values, and less years of formal education (p value <0.005 in all comparisons). Radiological damage was greater in unemployed patients but this difference did not reach statistical significance. In multivariate analysis, disease activity was the main variable associated with unemployment in both groups. Joint involvement was the main cause of work disability in this cohort of patients with early arthritis, independently of the final diagnosis. KEY MESSAGES: 1. Work disability is higher in patients with inflammatory arthritis as compared to the general population. 2. Prevalence of work disability is comparable among patients with undifferentiated and rheumatoid arthritis. 3. Disease activity is the main disease variable associated with work disability.

OBJECTIVES: This study analysed the frequency of anterior uveitis (AU) and its correlations in a large cohort of patients with spondyloarthritis (SpA). METHODS: A common protocol of investigation was prospectively applied to 2012 SpA patients in 85 centres from 10 Ibero-American countries. Clinical and demographic variables and disease indexes were investigated. Categorical variables were compared by χ2 and Fisher's exact test, and continuous variables were compared by ANOVA or Kruskal-Wallis test. A value of p<0.05 was considered significant. RESULTS: AU was referred by 372 SpA patients (18.5%). AU was statistically associated with inflammatory low back pain (p<0.001), radiographic sacroiliitis (p<0.001), enthesopathies (p=0.004), urethritis/acute diarrhoea (p<0.001), balanitis (p=0.002), hip involvement (p=0.002), HLA-B27 (p=0.003), and higher C-reactive protein (p=0.001), whilst it was negatively associated with the number of painful (p=0.03) and swollen (p=0.005) peripheral joints, psoriatic arthritis (p<0.001), psoriasis (p<0.001), nail involvement (p<0.001), and dactilitis (p=0.062; trend). No association with gender, race, and indices (disease activity, functionality and quality of life) was observed. Logistic regression showed that ankylosing spondylitis (p=0.001) and HLA-B27 (p=0.083; trend) was significantly associated with AU, while extra-articular manifestations (predominantly psoriasis) were negatively associated (p=0.016). CONCLUSIONS: Anterior uveitis is a frequent extra-articular manifestation in SpA patients, positively associated with axial involvement and HLA-B27 and negatively associated with peripheral involvement and psoriatic arthritis.

OBJECTIVE: To describe differential characteristics of axial involvement in ankylosing spondylitis (AS) as compared with that seen in psoriatic arthritis (PsA) and inflammatory bowel disease (IBD) in a cohort of Ibero-American patients. METHODS: This study included 2044 consecutive patients with spondyloarthritis (SpA; ESSG criteria). Demographic, clinical, disease activity, functional ability, quality of life, work status, radiologic, and therapeutic data were evaluated and collected by RESPONDIA members from different Ibero-American countries between June and December 2006. Patients selected for analysis met modified New York criteria (mNY) for AS. RESULTS: A total of 1264 patients met the New York criteria for AS: 1072 had primary AS, 147 had psoriatic, and 45 had IBD-associated spondylitis. Median disease duration was comparable among the 3 patient groups. Patients with primary AS were significantly younger (p = 0.01) and presented a higher frequency of males (p = 0.01) than the other 2 groups. Axial manifestations such as inflammatory back pain and sacroiliac pain were significantly more frequent in patients with primary AS (p = 0.05) versus other groups, whereas frequency of dactylitis, enthesitis, and peripheral arthritis was more common in patients with psoriatic spondylitis (p = 0.05). Spinal mobility was significantly more limited in patients with primary AS versus the other 2 groups (p = 0.0001). Radiologic changes according to BASRI total score were equally significant in primary AS. Disease activity (BASDAI), functional ability (BASFI), and quality of life (ASQoL) scores were comparable in the 3 groups. CONCLUSION: Patients with primary AS had more severe axial involvement than those with spondylitis associated with psoriasis or IBD. Functional capacity, disease activity, and quality of life were comparable among the groups studied.

INTRODUCTION: Spondyloarthritis (SpA) includes a group of diseases that share immunogenetic, clinical and radiologic findings, with a particular involvement of the axial skeleton and the entheses. METHODS: SpA patients attending ambulatory care in 11 rheumatology services located in 6 Argentine provinces were included in a prospective, observational multicentre cohort of SpA in Argentina (Iberoamerican Spondyloarthritis Registry [RESPONDIA]). Data collected were transmitted online and stored in the Spanish spondyloarthritis registry (REGISPONSER) Web site. Sociodemographic, clinical features and diagnosis, disease activity, functional status, quality of life, work status, radiographic changes and treatment data were collected by means of validated tools. RESULTS: A total of 402 patients were included; 59% were male, with median age of 48.3 years and median disease duration of 8 years; 68.7% of patients belonged to middle and lower-middle social classes. Eighty-six patients were diagnosed with ankylosing spondylitis (AS), 242 with psoriatic arthritis, 25 with reactive arthritis, 10 with SpA associated with inflammatory bowel disease, 33 with undifferentiated SpA and 6 with juvenile AS. The median score was 2.6 for the Bath AS Functional Index, 3.8 for the Bath AS Disease Activity Index and 5 for the Bath AS Radiology Index. The lower social class patients achieved a worse Bath AS Functional Index than other social classes and a worse Bath AS Disease Activity Index, compared with upper-middle class. CONCLUSIONS: The sociodemographic distribution pattern observed in these SpA patients was similar to that expected in the general population of Argentina, with worse functional capacity and higher disease activity observed in the lower social classes.

OBJECTIVE: The aim of the present study is to describe the general characteristics of a cohort of patients with early arthritis in Argentina. METHODS: CONAART (Consorcio Argentino de Artritis Temprana--Argentine Consortium for Early Arthritis) is an initiative of seven rheumatology centres across Argentina. Patients were included if they had at least one or more swollen joints and <2 years of disease duration. Social, demographic, familiar, hereditary, clinical and laboratory data were recollected. At first visit and every year, X-rays of hands and feet were performed and working characteristics and pharmaco-economic data were re-collected. RESULTS: A total of 413 patients were included. Of them, 327 (79.2%) were women with a median age of 49 years and a median disease duration of 6 months. Of the total, 183 (44.3%) had RA (ACR 1987) and 167 (40.4%) undifferentiated arthritis (UA). Other diagnoses included: 12 crystalics, 11 PsA, 6 uSpA, 6 other CTD, 1 AS and 27 other diagnosis. As 85% of our population had RA and UA, we only compared these two groups of patients. Patients with RA had significantly worse activity parameters of the disease (DAS of 28 joints), functional capacity (HAQ) and quality of life (Rheumatoid Arthritis Quality of Life) than patients with UA. The frequency of RF and anti-CCP, and symmetrical distribution were also significantly higher in patients with RA compared with UA patients. All patients with RA initiated early specific treatment, in a period no longer than 6 months from the beginning of the disease. CONCLUSION: Early arthritis clinics are a useful tool to identify and treat patients with different forms of joint involvement.

OBJECTIVE: Analyze disability determinants in a cohort of Argentine patients with rheumatoid arthritis (RA). MATERIAL AND METHODS: Consecutive patients with RA, according to ACR'87 criteria, were recruited from 6 rheumatology centers. Demographic and socioeconomic data, family history, comorbid diseases, extra-articular manifestations and information about received treatments were provided. Disease activity was assessed using Disease Activity Score 28 (DAS 28) and the Health Assessment Questionnaire (HAQ)-A was used for the functional capacity. Hand and feet radiographs were assessed using Sharp-van der Heijde score. RESULTS: A total of 640 patients with RA were included, of which 85.2% were females. Mean age was 53 years (interquartile range [IQR], 44-62) and mean disease duration was 8 years (IQR, 4-14). DAS 28 mean was 2.72 (IQR, 1.7-3.7) and HAQ-A mean was 0.62 (IQR, 0.13-1.25). Multiple linear regression showed that the main variables associated with disability were DAS 28, radiologic damage and age. Main predictors of functional disability in the multiple logistic regression using severe HAQ (>2) as dependent variable were DAS 28 (OR, 2; P < 0.0001); age (OR, 1; P = 0.008); and structural damage (OR, 1; P = 0.001). CONCLUSIONS: In this population, the disease activity was the variable that showed the highest impact on the physical function. Radiologic damage affected HAQ as the disease progressed.

Introducción: La eritrosedimentación (VSG), la leucopenia, la linfopeniay los anticuerpos anti-DNA de doble cadena (anti-DNAn), se han asociado con la actividad del lupus eritematoso sistémico (LES). Su relación con el daño acumulado no es clara. Objetivo: Determinar si la elevación de la VSG, la leucopenia, la linfopenia y el anti-DNAn se relacionan con la actividad o el daño acumulado. Métodos: Se revisaron historias clinicas de pacientes con LES de tres centros de reumatología. Se registraron hemograma, VSG, anti DNAny actividad del LES (SLEDAI) en la primera consulta, cada tres a seis meses y en caso de sospecha de activación. Se evaluó daño orgánico (SLICC/ACR), al primero, tercero, quinto y décimo año de seguimiento. Para analizar leucopenia y actividad de LES, se elaboró una escala sin leucopenia (SLEDAI-L). Los pacientes fueron distribuidos en cuatro grupos de acuerdo al promedio de VSG, leucocitos, linfocitos y clasificados como anti-DNAn positivos o negativos. La media del promedio del SLEDAI y del último SLICC/ACR fueron comparadas entre los grupos de VSG, recuento de linfocitos y entre pacientes anti-DNAn positivos o negativos. La media del promedio de SLEDAI-L y del último SLICC/ACR se compararon entre los grupos de leucocitos. Resultados: De 86 pacientes (75 mujeres, edad media 35,5 ± 10,8 años), 60% tuvieron VSG elevada leve, con un promedio de recuento de leucocitos y linfocitos normal de 92% y 65%, respectivamente y 58% fueron anti-DNAn negativo. La comparación de la media del promedio de SLEDAI y el promedio de SLICC/ACR entre los grupos de VSG, recuento de linfocitos y entre pacientes anti-DNAn positivo y negativo no mostró diferencias significativas, de la misma forma que la media de SLEDAI-L y de SLICC/ACR entre los grupos de recuento de leucocitos. Conclusión: El promedio de elevación de VSG, leucopenia y linfopenia y el anti-DNAn no mostraron asociación con la actividad o el daño acumulado por el LES.

The goals of this study were to ascertain damage in patients with systemic lupus erythematosus (SLE) from five rheumatologic centres in Argentina and to examine overall damage, damage by domain and damage by item within each domain. We performed a retrospective observational study including patients with SLE (ACR 1997 revised and modified criteria) from five rheumatology centres in Argentina. Organ damage was scored using the SLICC/ACR DI (SDI), ascertained at years 1, 2, 5 and 10. Three centres provided information up to the fifth year. Of the 197 patients, 88.3% were women and their mean age was 33.2 years. The mean disease duration and follow-up were 7.6 and 5.3 years, respectively. Damage accrued gradually over time with SDI ranging from 0.52 (+/-1.1) at year 1 up to 2.46 (+/-2.1) at year 10. The renal system was the most involved system, followed by the neuropsychiatric, the cardiovascular and the musculoskeletal systems. Proteinuria, cognitive impairment, pericarditis, avascular necrosis, cataract and alopecia were the predominant items in their respective systems. Systems such as peripheral vascular, pulmonary, gastrointestinal, diabetes, malignancy and premature gonadal failure were not frequent. Overall SDI had a gradual increase over time. Damage in each domain of SDI, except for diabetes, had a similar behaviour. Behaviour of items in each domain varied.

BACKGROUND: The Health Assessment Questionnaire (HAQ) is one of the most frequently used instruments to assess functional capacity in activities of daily living. OBJECTIVE: The objective of our study was to determine the reproducibility and validity of an Argentinean version of the HAQ disability index (HAQ-DI) in patients with rheumatoid arthritis (RA). METHODS: Consecutive adult patients with RA from 3 different provinces in Argentina were included. The original English version of the HAQ-DI was translated and adapted into Spanish by 3 rheumatologists and the final version back translated into English by a bilingual person. The reproducibility of the questionnaire was assessed in 30 patients who came for a second visit 3 to 5 days later. The cross-sectional construct validity was assessed by comparing the HAQ with classic parameters of disease activity (number of swollen and tender joints, patient and physician visual analog scale for pain and activity as well as functional class, erythrocyte sedimentation rate, and C-reactive protein. RESULTS: Two hundred patients with RA were included. The reproducibility was r = 0.97 (P = 1 x 10-5); intraitem correlation analysis did not show any redundancy. Correlation between HAQ-A and parameters of disease activity were all significant. A stepwise multiple regression analysis showed that the main variables associated with HAQ-A scores were visual analog scale for pain and duration of morning stiffness. A weak although significant negative correlation was found between the HAQ-A and economic level (r = -0.21, P = 0.03). The median time to complete the questionnaire was 5 minutes and there were no problems with any questions. CONCLUSION: This version of the HAQ-DI would allow for more availability so that Spanish-speaking countries can select the version most suitable to their sociocultural environment.
RESUMO
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.

El presente trabajo es el resultado de nuestra investigación acerca de las enfermedades del tejido conectivo durante el curso de la infección por el virus de inmunodeficiencia humana (HIV). Se determinó en forma prospectiva la prevalencia y características de las manifestaciones reumáticas en 101 pacientes infectados por el virus HIV. El sistema musculoesquelético estuvo comprometido en 72 pacientes: astralgias 35, síndrome de Reiter 10, artritis psoriásica 2, polimiositis 2, vasculitis 2. Artritis en 12 pacientes (oligoarticulares 6, monoarticulares 3 y poliarticulares 3), comprometiendo extremidades inferiores, de 1 semana a seis meses de duración y un cuadro de "Síndrome Articular Doloroso" (SAD en 10 pacientes, caracterizado por dolor articular severo e incapacitante, de grandes articulaciones, sin evidencia de sinovitis.
