Abstract
Objectives To assess the effectiveness, safety, and drug survival of subcutaneous (SC) abatacept (ABA) in a cohort of rheumatoid arthritis (RA) patients in a real-world setting. Methods This was a retrospective cohort study from 2014 to 2018 in which patients with RA (1987 ACR criteria) were included. Patients were evaluated at a single rheumatology outpatient center in Bogotá, Colombia. The patients were classified according to their treatment background: biological-naïve (n = 65), switched from IV to SC ABA administration (125 mg-wk) (n = 32), and inadequate response to biological DMARD (n = 62). The primary endpoint was a change in DAS28-CRP and RAPID3 from baseline to 12 months. A linear mixed effect model was used to correlate repeated measures. Adverse events were assessed and recorded during each visit to the rheumatology center. Several Cox proportional hazard regression models were used to test if there were any differences in drug survival curves based on seropositivity for rheumatoid factor (RF), and anti-Cyclic Citrullinated Peptide Antibodies (anti-CCP). Statistical analysis was done using software R version 3.4.4. Results A total of 159 patients were included. Baseline characteristics of patients were as follows: female gender 84%, median age of 54 years (IQR 16), median disease duration 10 years (11), RF positive 96%, anti-CCP positive 89%, erosive disease 55%, median DAS28-CRP 5.0 (2), and median RAPID3 17 (10). Concomitant use of methotrexate and SC ABA monotherapy were reported at 52% and 30% respectively. Demographics and disease characteristics were similar for all groups, except for baseline DAS28-CRP, and RAPID3 in the group that switched route of administration. The interaction between time and group was significant (p = 0.0073) for RAPID3. Infections, constitutional symptoms, and headaches were the most frequent AEs. Retention rate corresponded to 60% at 48 months. The most frequent reason for drug suspension was loss of efficacy. Median time of treatment for SC ABA was 31 months (IQR 30). The only association that reached statistical significance was anti-CCP concentration [Q1–Q4] (p = 0.005). According to the Cox proportional hazard regression model, there were significant differences between survival curves for Q1 (HR 0.15; 0.03–0.64 95% CI; p = 0.0096), and Q2 (HR 0.28; 0.08–0.92 95% CI; p = 0.0363) compared to the seronegative group. Conclusions The results showed an improvement in RA disease activity and physical function in patients under SC ABA treatment. Patients switching from IV to SC administration of ABA had lower activity and functional impairment at baseline. SC ABA demonstrated a good safety profile consistent with previously published data. Patients with baseline levels of anti-CCP antibody concentrations had better drug survival than seronegative patients. Only a few studies have evaluated the effectiveness and safety of ABA in patients with RA in routine clinical practice. RAPID3 appears to be an attractive option for evaluating disease activity in RA patients in a real-life setting. SC administration of ABA demonstrates a safety profile consistent with previously published data. Prognostic factors for drug retention have not been explored thoroughly despite data for ABA being available from national registries. SC ABA survival tends to be better in a subset of anti-CCP seropositive patients with RA.

Abstract
The objective of the study is to find predictors of remission, radiographic progression (RP), and erosive disease in a cohort of patients with early onset rheumatoid arthritis (EORA) that followed a therapeutic protocol aiming at remission, in a real world tight-control setting. EORA patients were enrolled in a 3-year follow-up study. Clinical, biological, immunogenetic, and radiographical data were analyzed. Radiographs were scored according to Sharp-van der Heijde (SvdH) method. RP was defined by an increase of 3 units in 36 months. Remission was defined as DAS28 <2.6. A stepwise multiple logistic regression model was used to identify independent predictors of the three target outcomes. One hundred twenty-nine patients were included. Baseline disease activity was high. Significant overall improvement was observed, but only 33.3 % achieved remission. At 36 month, 50.4 % (65) of patients showed erosions. RP was observed in 62.7 % (81) of cases. Statistical analysis showed that baseline SvdH score was the only predictive factor associated with the three outcomes evaluated. Lower HAQ-DI and absence of autoantibodies were predictive of remission. Higher levels of ESR and presence of erosions at entry were predictive of RP. Independent baseline predictors of incident erosive disease were anti-CCP and RF positivity, symptom duration at baseline >3 months, and presence of HLA-DRB1 shared epitope. Radiographic damage at baseline was the main predictor of outcomes. Autoantibodies, HAQ and ESR at baseline, symptom duration before diagnosis, and HLA-DRB1 status had influence on clinical course and development of structural joint damage in Colombian RA patients.

Abstract
In most ethnic groups genetic susceptibility to rheumatoid arthritis (RA) is associated with certain HLA-DRB1 alleles encoding a similar sequence motif called the 'shared epitope' (SE) spanning amino acid positions 70 to 74 in the third diversity region of the outermost domain of the HLA-DRB1 molecule. We examined the association of the SE and RA in 83 Colombian women with established RA and 90 healthy controls. The group HLA-DRB1*04 was associated with RA with respect to controls (47% vs 18%, respectively. OR: 4.1, 95%CI: 2.1-8.2, P < 0.001). HLA-DRB1 alleles carrying the SE QRRAA, but not those carrying QKRAA or RRRAA, were associated with disease (OR: 3.7, 95%CI: 1.73-7.83, P = 0.0009). This association was stronger among HLA-DRB1*04 carriers (OR: 23, 95%CI: 1.3-414, P = 0.002). In our population, the SE QRRAA expressed in DRB1*04 alleles appears critical in identifying women with increased susceptibility to RA.

Abstract
OBJECTIVES Little data is available on the prevalence and incidence of rheumatoid arthritis (RA) or the genetic and environmental factors that influence RA risk and severity in non-Caucasian populations. The prevalence of RA in Caucasians and some Native American populations is 1% or more; in contrast, low prevalences of RA have been reported in some African populations. We determined the hospital incidence (HI) and period prevalence (PP) of RA in African Colombians in Quibdo, Colombia, by using data collected at the Hospital San Francisco de Asis, a primary-to-tertiary care center. Genetic and immunologic studies of factors that influence RA risk and severity, such as HLA genes, immunoglobulin-A (IgA) rheumatoid factor (RF), and antikeratin antibodies (AKA) were performed. African Colombians with RA also were compared with Mestizo RA patients from Medellín, Colombia. METHODS To determine the HI, all the outpatient charts for 1995 were reviewed (n = 3,044). PP during 1996 (Jan-Dec) was assessed by stratified sampling of all African Colombians aged 18 or more having arthralgia. Participants completed a survey and a pretested standard questionnaire, had hands and feet X-rays, and provided a blood sample. Total and IgA RF were measured by turbidimetry and ELISA, respectively; AKA were assessed by indirect immunofluorescence on rat esophagus. HLA-DRB1 and DQB1 alleles were determined by polymerase chain reaction technique with primers of specific sequence and by reverse dot blot. RESULTS The HI was 0.65 cases per 1,000 person years. There were 321 individuals with arthralgia (0.3%; 95% CI, 0.28-0.3), 18 of whom fulfilled the American College of Rheumatology criteria for RA (PP in the general population, 0.01%; 95% CI, 0.008-0.02). Lower erosion scores were seen in African Colombian patients compared to Mestizos (n = 56), although duration of disease was similar in each group. No association between any HLA allele and RA risk or RA severity or between autoantibodies and RA severity was observed in African Colombians. Comparisons showed no significant differences between African Colombians and Mestizo patients in the presence of RF (total and IgA), AKA, age at onset, extra-articular manifestations, formal education level, and history of malaria. CONCLUSIONS These results suggest that RA in African Colombian patients from Quibdo is rare, may be less severe in terms of radiographic damage than in Colombian Mestizo patients, and lacks association to HLA-DRB1 and DQB1 alleles. Additionally, RF (total and IgA) and AKA are not markers of progression and activity of the disease in this population.
