ABSTRACT

INTRODUCTION: This study assesses the accuracy of neutrophil activation markers, including neutrophil extracellular traps (NETs) and calprotectin, as biomarkers of disease activity in patients with established rheumatoid arthritis (RA). We also analyse the relationship between NETs and various types of therapies as well as their association with autoimmunity. METHODS: Observational cross-sectional study of patients with RA receiving treatment with biological disease-modifying antirheumatic drugs or Janus kinase inhibitors (JAK-inhibitors) for at least 3 months. Plasma calprotectin levels were measured using an enzyme-linked immunosorbent assay test kit and NETs by measuring their remnants in plasma (neutrophil elastase-DNA and histone-DNA complexes). We also assessed clinical disease activity, joint ultrasound findings and autoantibody status [reumatoid factor (RF), anti-citrullinated peptide/protein antibodies (ACPAs) and anti-carbamylated protein (anti-CarP)]. Associations between neutrophilic biomarkers and clinical or ultrasound scores were sought using correlation analysis. The discriminatory capacity of both neutrophilic biomarkers to detect ultrasound synovitis was analysed through receiver-operating characteristic (ROC) curves. RESULTS: One hundred fourteen patients were included. Two control groups were included to compare NET levels. The active control group consisted of 15 patients. The second control group consisted of 30 healthy subjects. Plasma NET levels did not correlate with clinical disease status, regardless of the clinic index analysed or the biological therapy administered. No significant correlation was observed between NET remnants and ultrasound synovitis. There was no correlation between plasma NET and autoantibodies. In contrast, plasma calprotectin positively correlated with clinical parameters (swollen joint count [SJC] rho = 0.49; P < 0.001, Clinical Disease Activity Index [CDAI] rho = 0.30; P < 0.001) and ultrasound parameters (rho > 0.50; P < 0.001). Notably, this correlation was stronger than that observed with acute phase reactants. CONCLUSION: While NET formation induced by neutrophils may play a role in RA pathogenesis, our study raises questions about the utility of NET remnants in peripheral circulation as a biomarker for inflammatory activity. In contrast, this study strongly supports the usefulness of calprotectin as a biomarker of inflammatory activity in patients with RA.

ABSTRACT

BACKGROUND: this is an exploratory study to evaluate calprotectin serum levels in patients with rheumatic immune-related adverse events (irAEs) induced by immune checkpoint inhibitor (ICI) treatment. METHODS: this is a retrospective observational study including patients with irAEs rheumatic syndromes. We compared the calprotectin levels to those in a control group of patients with RA and with a control group of healthy individuals. Additionally, we included a control group of patients treated with ICI but without irAEs to check calprotectin levels. We also analysed the performance of calprotectin for the identification of active rheumatic disease using receiver operating characteristic curves (ROC). RESULTS: 18 patients with rheumatic irAEs were compared to a control group of 128 RA patients and another group of 29 healthy donors. The mean calprotectin level in the irAE group was 5.15 µg/mL, which was higher than the levels in both the RA group (3.19 µg/mL) and the healthy group (3.81 µg/mL) (cut-off 2 µg/mL). Additionally, 8 oncology patients without irAEs were included. In this group, calprotectin levels were similar to those of the healthy controls. In patients with active inflammation, the calprotectin levels in the irAE group were significantly higher (8.43 µg/mL) compared to the RA group (3.94 µg/mL). ROC curve analysis showed that calprotectin had a very good discriminatory capacity to identify inflammatory activity in patients with rheumatic irAEs (AUC of 0.864). CONCLUSIONS: the results suggest that calprotectin may serve as a marker of inflammatory activity in patients with rheumatic irAEs induced by treatment with ICIs.

ABSTRACT

BACKGROUND: Patient global assessment (PATGL) is a component of rheumatoid arthritis (RA) and spondyloarthritis (SpA) activity indices, reflecting inflammation in selected clinical trial patients. In routine care, PATGL often may be elevated independently of inflammatory activity by fibromyalgia (FM) and/or depression, leading to complexities in interpretation. A feasible method to screen for FM and/or depression could help to clarify interpretation of high PATGL and index scores, including explanation of apparent limited responses to anti-inflammatory therapies. PATIENTS AND METHODS: Patients with RA or SpA in routine care in Barcelona, Chicago, and Sydney complete a 2-page multidimensional health assessment questionnaire (MDHAQ) in 5-10 min. The MDHAQ includes PATGL and three indices, RAPID3 (routine assessment of patient index data) to assess clinical status, FAST4 (0-4 fibromyalgia assessment screening tool) and MDS2 (0-2 MDHAQ depression screen). PATGL was compared for each diagnosis at each site and pooled data in FAST4 positive (+) vs negative (-) and/or MDS2+ vs MDS2- patients using medians and median regressions. RESULTS: Median PATGL was 5.0 in 393 RA and 175 SpA patients; 2.0-3.0 in 305 (58.9%) FAST4-,MDS2- patients, 5.5-6.0 in 71 (13.7%) FAST4-,MDS2+ patients, 7.0-7.5 in 50 (9.7%) FAST4+,MDS2- patients, and 7.0-8.0 in 92 (17.8%) FAST4+,MDS2+ patients. Positive FAST4 and/or MDS2 screens were seen in 41% of patients. Results were similar in RA and SpA at 3 settings on 3 continents. CONCLUSION: Median 0-10 PATGL varied from 2-3/10 to 5.5-8/10, according to negative vs positive screening for FM and/or depression on a single MDHAQ for busy clinical settings.

ABSTRACT

Objectives: To analyse the accuracy of plasma calprotectin in patients with rheumatoid arthritis (RA) receiving monoclonal antibodies against IL-6 receptors (anti-rIL-6) or JAK inhibitors (JAKis) in detecting ultrasound (US) synovitis and compare it with acute phase reactants [high-sensitivity C-reactive protein (hs-CRP) and ESR]. Methods: An observational cross-sectional study of RA patients receiving anti-rIL-6 (tocilizumab or sarilumab) or JAKi, (baricitinib or tofacitinib) was made. Plasma calprotectin for the diagnosis of US synovitis [synovial hypertrophy grade (SH) ⩾ 2 plus power Doppler signal (PD) ⩾ 1] was analysed using receiver operating characteristic curves (ROCs). The performance of ESR and hs-CRP was also studied. The three ROC curves were compared to determine which had the highest discriminatory power. Associations between plasma calprotectin and US scores were made using correlation analysis. Results: Sixty-three RA patients were included. Mean plasma calprotectin levels were significantly higher in patients with US synovitis than in those without (0.89 ± 0.85 vs 0.30 ± 0.12 µg/ml; p = 0.0003). A moderate correlation between calprotectin and all US scores (HS score Rho = 0.479; PD score Rho = 0.492; and global score Rho = 0.495) was found. The discriminatory capacity of plasma calprotectin showed an AUC of 0.795 (95% CI: 0.687-0.904). The AUC of hs-CRP and ESR was 0.721 and 0.564, respectively. hs-CRP serum levels showed a low positive correlation with the three US scores (Rho < 0.40). After analysis according to the drugs administered, the correlation disappeared in patients receiving anti-rIL-6. Conclusion: Plasma calprotectin may be a sensitive biomarker of synovial inflammation in RA patients treated with anti-rIL-6 or JAKi.

ABSTRACT

Immune checkpoint inhibitor (ICI)-induced arthritis is an increasingly recognized adverse event in patients with oncologic disease during immunotherapy. Four patterns are well described, including rheumatoid arthritis (RA)-like, polymyalgia rheumatica (PMR)-like, psoriatic arthritis (PsA)-like, and oligo-monoarthritis, among others. Despite better clinical recognition of these syndromes, information about the main imaging findings is limited. METHODS: We conducted a retrospective observational study including all adult patients referred to the Rheumatology Department of a single-center due to ICI-induced arthritis who underwent imaging studies [ultrasound (US), magnetic resonance imaging (MRI), and 18F-FDG PET/CT)] between January 2017 and January 2022. RESULTS: Nineteen patients with ICI-induced arthritis with at least one diagnostic imaging assessment were identified (15 US, 4 MRI, 2 18F-FDG PET/CT). Most patients were male (84.2%), with a median age at inclusion of 73 years. The main underlying diagnoses for ICI treatment were melanoma in five cases. The distribution of ICI-induced arthritis was as follows: PMR-like (5, 26.2%), RA-like (4, 21.1%), PsA-like (4, 21.1%), and others (6, 31.6%). All RA-like patients had US findings indistinguishable from conventional RA patients. In addition, 3/5 (60%) of PMR-like patients had significant involvement of the hands and wrists. Abnormal findings on MRI or PET-CT were reported by clinical symptoms. No erosions or myofascitis were seen. CONCLUSIONS: ICI-induced arthritis patients present inflammatory patterns on imaging studies similar to conventional inflammatory arthropathies, and therefore these syndromes should be followed carefully and treated according to these findings.

ABSTRACT

BACKGROUND: Calprotectin is a calcium-binding protein that can be measured in serum, plasma, and feces. Increased serum and plasma calprotectin concentrations have been found in chronic inflammatory rheumatic disorders. An analytical and clinical evaluation of the DiaSorin Liaison® fecal Calprotectin assay using LIAISON® XL was performed. METHODS: The protocol included an analytical and clinical evaluation in which imprecision, the linearity of dilution, differences between serum and plasma samples and method comparison with CalproLab™ ELISA kit were assessed. Serum calprotectin concentrations in active (n = 26) and remission (n = 23) rheumatoid arthritis (RA) patients were compared. RESULTS: The intra-day and inter-day analytical imprecision CVs ranged from 2.9% to 4.0% and 2.7% to 10.4%, respectively. Correlation between measured and expected values was high (R > 0.99), indicating good linearity. The Wilcoxon signed-rank test showed that serum and plasma matched samples presented statistically significant differences (p < 0.001) being the highest concentrations of calprotectin observed in serum samples. Deming regression equation was as follows: Diasorin calprotectin (µg/ml) = -0.32 (95% CI: -0.65 - -0.05) +1.58 (95% CI: 1.42-1.79).* Calprolab calprotectin (µg/ml). Significantly higher serum calprotectin levels were found in RA patients with active disease when compared to patients with low disease activity or in clinical remission (mean ± SD) [(3.35 µg/ml ± 1.55) vs. (1.63 µg/ml ± 0.52), p < 0.001] and these levels correlated well with all disease activity indices. CONCLUSIONS: The DiaSorin Liaison® fecal Calprotectin assay adapted for serum samples showed adequate technical performances and the clinical performances were similar to other assays.

ABSTRACT

BACKGROUND: We examined whether high-sensitivity CRP (hsCRP) reflected the inflammatory disease status evaluated by clinical and ultrasound (US) parameters in RA patients receiving IL-6 receptor antibodies (anti-IL-6R) or JAK inhibitors (JAKi). METHODS: We conducted a cross-sectional study of patients with established RA receiving anti-IL-6R (tocilizumab, sarilumab) or JAKi (tofacitinib, baricitinib). Serum hsCRP and US synovitis in both hands were measured. Associations between hsCRP and clinical inflammatory activity were evaluated using composite activity indices. The association between hsCRP and US synovitis was analyzed. RESULTS: 63 (92% female) patients (42 anti- IL-6R and 21 JAKi) were included, and the median disease duration was 14.4 (0.2-37.5) years. Most patients were in remission or had low levels of disease. Overall hsCRP values were very low, and significantly lower in anti-IL-6R patients (median 0.04 mg/dL vs. 0.16 mg/dL). Anti-IL-6R (82.4%) patients and 48% of JAKi patients had very low hsCRP levels (≤0.1 mg/dL) (p = 0.002). In the anti-IL-6R group, hsCRP did not correlate with the composite activity index or US synovitis. In the JAKi group, hsCRP moderately correlated with US parameters (r = 0.5) but not clinical disease activity, and hsCRP levels were higher in patients with US synovitis (0.02 vs. 0.42 mg/dL) (p = 0.001). CONCLUSION: In anti-IL-6R RA-treated patients, hsCRP does not reflect the inflammatory disease state, but in those treated with JAKi, hsCRP was associated with US synovitis.

ABSTRACT

Palindromic rheumatism (PR), a unique clinical entity, has a characteristic clinical presentation with a relapsing/remitting course. It is established that most patients with PR evolve to chronic disease, of which rheumatoid arthritis (RA) is by far the most common. The relationship between PR and RA is unclear, with similarities and differences between the two, and not all patients evolve to RA in the long-term. Therefore, PR is clearly a pre-RA stage for most, but not all, patients. Autoimmunity plays a substantial role in PR, with the same characteristic autoantibody profile observed in RA, although with some differences in the immune response repertoire. Autoinflammation may also be relevant in some cases of PR. Prognostic factors for RA progression are identified but their exact predictive value is not clear. There are several unmet needs in PR, such as the diagnostic criteria and clinical case definition, the pathogenic mechanisms involved in the unusual clinical course, and the evolution to RA, and our understanding of the therapeutic strategy that could best avoid progression to persistent and potentially destructive arthritis.

ABSTRACT

OBJECTIVE: To analyze the use of the Multidimensional Health Assessment Questionnaire (MDHAQ) to screen for depression, as compared to 2 reference standards, the Patient Health Questionnaire 9 (PHQ-9) and the Hospital Anxiety and Depression Scale depression domain (HADS-D). METHODS: Patients from Barcelona with a primary diagnosis of rheumatoid arthritis (RA) or spondyloarthritis (SpA) completed the MDHAQ, the PHQ-9 (depression ≥10), and the HADS-D (depression ≥8) measures. The MDHAQ includes 2 depression items, 1 in the patient-friendly HAQ, scored in a 4-point format from 0 to 3.3, and a yes/no item on a 60-symptom checklist. Percentage agreement and kappa statistics quantified the agreement between 6 screening criteria: yes on the 60-symptom checklist, a score of ≥1.1, a score of ≥2.2 on a 4-point scale, and either a response of yes on the 60-symptom checklist or scores of ≥2.2, PHQ-9 ≥10, and HADS-D ≥8. RESULTS: Depression screening was positive according to 6 criteria in 19.6-32.4% of 102 patients with RA, and 27.9-44.8% of 68 with SpA (total = 170). All MDHAQ scores, including depression items, were higher in patients with SpA compared to patients with RA, and within each diagnostic group in patients who met PHQ-9 ≥10 and HADS-D ≥8 depression screening criteria. The highest percentage agreement between an MDHAQ screening criterion versus PHQ-9 ≥10 was 83.3% for either an answer of yes on the 60-symptom checklist or a score of ≥2.2 on a 4-point scale, which we have termed MDHAQ-Dep. The agreement of MDHAQ-Dep versus HADS-D ≥8 was 81.7%, similar to the agreement of PHQ-9 ≥10 versus HADS-D ≥8, which was 82.2%. Kappa measures of agreement were 0.63 for MDHAQ-Dep versus PHQ-9 ≥10, 0.60 for MDHAQ-Dep versus HADS-D ≥8, and 0.62 for PHQ-9 ≥10 versus HADS-D ≥8. CONCLUSION: A positive MDHAQ-Dep response (either an answer of yes on a 60-symptom checklist or a score of ≥2.2 on a 4-point scale) yielded similar results to PHQ-9 ≥10 or HADS-D ≥8 to screen for depression in these RA and SpA patients.

ABSTRACT

BACKGROUND: A restricted response against citrullinated peptides/proteins, with less isotype usage, has been found in palindromic rheumatism (PR) in comparison with rheumatoid arthritis (RA). We hypothesized that this different antibody response may be observed for other post-translational modified proteins. We compared the prevalence and isotype usage of two specificities of anti-carbamylated peptide/protein antibodies (Anti-CarP) in patients with PR and RA. METHODS: Cross-sectional study including 54 patients with pure PR and 53 patients with RA, matched by sex, age, disease duration and ACPA. Anti-CarP specificities were determined by home-made enzyme-linked immunosorbent assay tests using a synthetic chimeric fibrin/filaggrin homocitrullinated peptide (CFFHP) and fetal calf serum (FCS) homocitrullinated protein as antigens. IgG, IgA and IgM isotypes were measured. RESULTS: Anti-CarP were positive (CFFHP or FCS) in 24% and 64% of patients with PR and RA, respectively (p < 0.005). All Anti-CarP isotype proportions were significantly lower in PR than in RA: Anti-CarP-IgG (24% versus 51%), Anti-CarP-IgA (7% versus 34%) and Anti-CarP-IgM (7% versus 36%). Mean titers of Anti-CarP isotypes were also lower in PR. In Anti-CarP positive patients, the isotype distribution differed between PR and RA: IgG Anti-CarP was used in all PR patients and in 79% of RA patients. By contrast, a significantly lower isotype usage of both IgA (31% versus 53%) and IgM (31% versus 56%) was observed in PR patients. No significant differences in clinical or demographic characteristics were observed according to Anti-CarP status in PR patients, except for a higher prevalence of ACPA and higher mean titers of ACPA and rheumatoid factor in Anti-CarP positive patients. CONCLUSION: Anti-CarP are found in patients with PR but in a lower proportion and with a different isotype usage from in RA, suggesting a distinct B cell response to homocitrullinated antigens in PR.

ABSTRACT

OBJECTIVE: To analyze the prevalence of preexisting palindromic rheumatism (PR) in patients with established rheumatoid arthritis (RA) and to evaluate whether these patients have a distinctive clinical and serological phenotype. METHODS: Cross-sectional study in patients with established RA. Preexisting PR was determined using a structured protocol and confirmed by retrospective review of medical records. Demographic, clinical, radiological, immunological, and therapeutic features were compared in patients with and without PR. RESULTS: Included were 158 patients with established RA (78% female) with a mean disease duration since RA onset of 5.1 ± 2.7 years. Preexisting PR was recorded in 29 patients (18%). The median time from the onset of PR to progression to RA was 1.2 years. No between-group differences in demographic features, current disease activity, radiographic erosive disease, or disability were observed. Patients with PR had a higher prevalence of smoking (72% vs 40%). Positive rheumatoid factor, anticitrullinated peptide antibodies, and anticarbamylated protein antibodies were numerically higher in patients with PR. No differences in treatment were observed except for greater hydroxychloroquine (HCQ) use in patients with PR (38% vs 6%). Palindromic flares persisted in a significant proportion of patients during the RA course, including patients in clinical remission or receiving biological disease-modifying antirheumatic drugs. CONCLUSION: Eighteen percent of patients with RA had a history compatible with PR previous to RA onset. No specific clinical or serological phenotype was identified in these patients, although higher HCQ use and smoking prevalence were identified. Palindromic flares may persist during the RA disease course despite treatment.

ABSTRACT

To assess the hypothesis if tocilizumab (TCZ) is effective on disease activity, and also its effect in fatigue and other clinical and psychological disease-related factors in patients with rheumatoid arthritis (RA) treated with TCZ.A 24-week, multicenter, prospective, observational study in patients with moderate to severe RA receiving TCZ after failure or intolerance to disease-modifying antirheumatic drugs or tumor necrosis factor-alpha was conducted.Of the 122 patients included, 85 were evaluable for effectiveness (85% female, 51.9 ±â€Š12.5 years, disease duration 8.7 ±â€Š7.4 years). Mean change in C-reactive protein level from baseline to week 12 was -11.2 ±â€Š4.0 (P < .001). Mean Disease Activity Index score (DAS28) decreased from 5.5 ±â€Š1.0 at baseline to 2.7 ±â€Š1.3 (P < .001) at week 24. Mean change in Functional Assessment of Chronic Illness Therapy score was -5.4 ±â€Š11.2 points at week 24. Multiple regression analysis showed that the improvement in DAS28, sleep, and depression explained 56% and 47% of fatigue variance at week 12 and 24, respectively.Tocilizumab is effective in reducing disease activity and results in a clinically significant improvement in fatigue, pain, swollen joint count, morning stiffness, sleepiness, depression, and DAS28; the last 3 were specifically identified as factors explaining fatigue variance with the use of TCZ in RA patients.

ABSTRACT

BACKGROUND: Recent data suggest that anti-TNF doses can be reduced in ankylosing spondylitis (AS) patients. Some authors even propose withdrawing treatment in patients in clinical remission; however, at present there is no evidence to support this. OBJECTIVE: To assess how long AS patients with persistent clinical remission remained free of flares after anti-TNF withdrawal and to evaluate the effects of treatment reintroduction. We also analyze the characteristics of patients who did not present clinical relapse. METHODS: Multicenter, prospective, observational study of a cohort of patients with active AS who had received infliximab as a first anti-TNF treatment and who presented persistent remission (more than 6 months). We recorded at baseline and every 6-8 weeks over the 12-month period the age, gender, disease duration, peripheral arthritis or enthesitis, HLA-B27 status, BASDAI, CRP, ESR, BASFI, and three visual analogue scales, spine global pain, spinal night time pain, and patient's global assessment. RESULTS: Thirty-six out of 107 patients (34%) presented persistent remission and were included in our study. After treatment withdrawal, 21 of these 36 patients (58%) presented clinical relapse during follow-up. Infliximab therapy was reintroduced and only 52% achieved clinical remission, as they had before the discontinuation of infliximab; in an additional 10%, reintroduction of infliximab was ineffective, obliging us to change the anti-TNF therapy. No clinical or biological factors were associated with the occurrence of relapse during the follow-up. CONCLUSIONS: Two thirds of patients in clinical remission presented clinical relapse shortly after infliximab withdrawal. Although the reintroduction of infliximab treatment was safe, half of the patients did not present the same clinical response that they had achieved prior to treatment withdrawal.

ABSTRACT

Objetivo. Evaluar la eficacia y la seguridad a corto plazo del tratamiento de pacientes con artritis reumatoide (AR) con rituximab (RTX) comparado con un anti-TNF (2TNF) tras retirada de un primer anti-TNF. Métodos. Estudio multicéntrico prospectivo, observacional, de práctica clínica de pacientes con AR grave refractaria a anti-TNF que recibieron RTX comparados con los que recibieron un 2TNF. Comparación de las variables de eficacia y respuesta EULAR buena/moderada a los 6 meses. Resultados. Ciento tres pacientes incluidos; 82 alcanzan seguimiento a 6 meses, 73,7% mujeres. Datos basales grupo RTX y 2TNF, respectivamente: 8,6 y 6,6 NAD, 8,8 y 7,5 NAI, 5,45 ± 1,28 y 5,18 ± 1,21 en DAS28 (p=0,048), 41 y 38,7mmHg de VSG, y 1,2 y 1,0 en HAQ. Mejoría en todos los parámetros en ambos grupos sin diferencias significativas (excepto mayor reducción de VSG con RTX). Ausencia de efectos adversos graves. Conclusiones. El uso de RTX en segunda línea de terapia biológica tras fallo a un primer anti-TNF en práctica clínica muestra mejoría en las variables de eficacia y funcionalidad a los 6 meses, sin presentar efectos adversos graves. Estos resultados no difieren de los observados tras el uso de un segundo anti-TNF en el mismo escenario clínico (AU)


Objective. to compare the short-term efficacy and safety of rituximab (RTX) therapy versus anti-TNF in rheumatoid arthritis (RA) patients after discontinuation of a first anti-TNF agent. Methods. prospective observational multicenter study in the clinical practice setting, involving patients with severe RA refractory to a first anti-TNF agent, who received either RTX or a second anti-TNF (2TNF), comparing the efficacy endpoints, EULAR response (Good/Moderate) and safety at 6 months. Results. 103 patients enrolled, 82 completed 6-month follow-up, 73.7% women. Baseline data for RTX and 2TNF groups, respectively: TJC, 8.6 and 6.6; SJC, 8.8 and 7.5; DAS28 score, 5.45 (±1.28) and 5.18 (±1.21) (p=0.048), ESR, 41 and 38.7mmHg; and HAQ, 1.2 and 1.0. Improvement was observed in all parameters, with no significant differences (except for a more marked reduction in ESR with RTX). There were no serious adverse events. Conclusions. RTX use as second-line therapy after anti-TNF failure led to improvements in the efficacy and functional variables at 6 months, with no serious adverse events. These results were comparable to those observed in patients who used a second anti-TNF agent in the same clinical scenario (AU)

ABSTRACT

OBJETIVO: Analizar el retraso diagnóstico y terapéutico en pacientes con AR de reciente comienzo en 19 centros de Catalunya. MÉTODOS: Encuesta epidemiológica en 183 pacientes en que se cuantificaron los tiempos en relación con el retraso diagnostico midiendo: 1) aparición del primer síntoma hasta la primera visita a Reumatología; 2) desde la derivación hasta la primera visita de Reumatología; 3) entre aparición del primer síntoma hasta el diagnóstico, y 4) entre aparición del primer síntoma hasta el inicio del primer FAME. Se definió la existencia de 6 dispositivos asistenciales diferenciados. RESULTADOS: El tiempo medio desde el inicio de los síntomas hasta la instauración de un FAME en pacientes con AR en Catalunya es muy largo (11 meses). Pacientes atendidos en dispositivos como consultas de AR, consultas especializadas en atención primaria y sobre todo en consultas de artritis de inicio son tratados de manera más temprana con FAME. Conclusión. La existencia de determinados dispositivos asistenciales es fundamental para mejorar la atención precoz en la AR


OBJECTIVE: Diagnosis and therapy of patients with early onset rheumatoid arthritis (RA) is influenced by accessibility to specialized care devices. We attempted to analyze the impact of their availability. METHODS: We analyzed time related to diagnosis delay measuring: 1) Time from first clinical symptoms to the first visit with the Rheumatologist; 2) Time from referral to the first visit of Rheumatology; 3) Time between first symptom until final diagnosis; 4) time between first symptom until the initiation of the first disease-modifying antirheumatic drug (DMARD). The presence of these 6 rheumatology devices was defined: 1) early arthritis monographic clinics, 2) RA monographic clinics, 3) Mechanisms for fast programming, 4) Algorithms for referral from primary care (PC), 5) rheumatology consultation services in PC and 6) consulting services in PC. RESULTS: The mean time from onset of symptoms to diagnosis or the establishment of a DMARD in RA patients in Catalonia is very long (11 months). Patients seen in rheumatology devices such as RA monographic clinics, rheumatology consultation in PC and specially in early arthritis clinics are treated early with DMARDs. Conclusion. the existence of monographic clinics or consulting in primary care centers is essential to improve early care of RA patients

ABSTRACT

OBJECTIVE: to compare the short-term efficacy and safety of rituximab (RTX) therapy versus anti-TNF in rheumatoid arthritis (RA) patients after discontinuation of a first anti-TNF agent. METHODS: prospective observational multicenter study in the clinical practice setting, involving patients with severe RA refractory to a first anti-TNF agent, who received either RTX or a second anti-TNF (2TNF), comparing the efficacy endpoints, EULAR response (Good/Moderate) and safety at 6 months. RESULTS: 103 patients enrolled, 82 completed 6-month follow-up, 73.7% women. Baseline data for RTX and 2TNF groups, respectively: TJC, 8.6 and 6.6; SJC, 8.8 and 7.5; DAS28 score, 5.45 (±1.28) and 5.18 (±1.21) (p=0.048), ESR, 41 and 38.7mmHg; and HAQ, 1.2 and 1.0. Improvement was observed in all parameters, with no significant differences (except for a more marked reduction in ESR with RTX). There were no serious adverse events. CONCLUSIONS: RTX use as second-line therapy after anti-TNF failure led to improvements in the efficacy and functional variables at 6 months, with no serious adverse events. These results were comparable to those observed in patients who used a second anti-TNF agent in the same clinical scenario.

ABSTRACT

The aim of this study was to assess nailfold capillaroscopic (NC) findings in patients with primary Sjögren's syndrome (PSS) with and without Raynaud's phenomenon (RP) as well as in the presence of positive anti-SSA/Ro and anti-SSB/La antibodies. Videocapillaroscopy was performed in 150 patients with PSS. Data collected included demographics, presence of RP, PSS symptoms, antinuclear antibodies, rheumatoid factor, anti-Ro, anti-La, anti-CCP, salivary scintigraphy, labial biopsy, and NC findings. RP was present in 32% of PSS, keratoconjunctivitis sicca in 91%, oral xerosis in 93%, and skin or genital xerosis in 53%. In patients with positive anti-SSA/Ro (75%) and positive anti-SSB/La (40%), NC showed normal findings in 53% of cases and non-specific in 36%. In patients with PSS, NC was normal in 51% of cases and non-specific in 34%. Scleroderma pattern was found in 14 patients. RP associated with PSS had non-specific capillaroscopy in 40% of cases (p = 0.1). Pericapillary haemorrhages (p = 0.06) and capillary thrombosis (p = 0.2) were not increased, but more dilated capillaries were detected in 48% of cases. Patients with positive anti-Ro and/or anti-La have not a distinct NC profile. Patients with RP associated with PSS had more dilated capillaries, but neither pericapillary haemorrhages nor capillary thrombosis was observed.
