RESUMEN

OBJECTIVES: The genetic contribution to psoriatic disease is substantial with a dominating influence of the HLA region. The profile of HLA class I genotypes likely contributes to shaping clinical phenotypes. Herein we aimed to explore such genotypes in cohorts of closely characterised subsets of psoriatic disease with special focus on psoriatic arthritis mutilans (PAM), a severe and rare form of psoriatic arthritis (PsA). METHODS: Cohorts of patients with the diagnosis of psoriasis vulgaris with or without arthritis (n=1217), psoriasis without arthritis (n=534), psoriatic arthritis without mutilating disease (n=337) and psoriatic arthritis mutilans (n=63) were collected and genotyped for HLA class I and II genes, with standardised methodologies. Cases were compared with a healthy control population (n=2468). Case-only and case-control association tests were performed to address the hypothesis of genetic contribution to clinical phenotypes. RESULTS: The presence of HLA-B*27 was strikingly increased in PAM (45%) compared with PsA without mutilating disease (13%) and with healthy controls (13%). However, within the PAM population, HLA-B*27 did not correlate with clinical markers such as number of mutilating joints, radiographic scoring, disease duration and age of disease onset. CONCLUSIONS: HLA-B*27 emerges as an important genotype marker for PAM.

RESUMEN

To study oral health in patients with rheumatoid arthritis (RA) with emphasis on disease activity and treatment of RA. In this prospective cohort study 81 RA patients [53 early untreated RA (EURA) and 28 chronic RA (CRA) patients with inadequate response to synthetic disease modifying antirheumatic drugs (DMARDs)], underwent rheumatological [Disease Activity Score (28-joint) DAS28] and dental examinations [Total Dental Index (TDI), Decayed Missing Filled Teeth (DMFT) and Decayed Missing Filled Surfaces (DMFS)]. For controls, 43 volunteers were examined. After the examinations, EURA patients started treatment with synthetic DMARDs, oral and intra-articular glucocorticoids. CRA patients were candidates for biological DMARDs. The patients were re-examined mean 16 months later. Results were analyzed with descriptive statistics and logistic regression. TDI was higher in both RA groups at baseline compared to controls [EURA: 2 (2-3); CRA: 2 (1-3); controls 1 (1-3), p = 0.045]. DMFT [rs 0.561 (p = 0.002)] and DMFS [rs 0.581 (p = 0.001)] associated with DAS28 at baseline in CRA patients. After follow-up, DAS28 associated positively with DMFT [rs 0.384 (p = 0.016)] and DMFS [rs 0.334 (p = 0.038)] in EURA patients; as well as in CRA patients DMFT [rs 0.672 (p = 0.001)], DMFS [rs 0.650 (p = 0.001)]. RA patients already in the early phase of the disease had poorer oral health compared to controls. The caries indices associated with the activity of RA in both patient groups. Oral status may thus contribute to the development and further relate to the activity of RA.

RESUMEN

OBJECTIVES: Predicted versus observed radiographic progression in early rheumatoid arthritis (POPeRA) was applied to demonstrate how various treatment modalities affect and potentially minimise radiographic progression over time. METHODS: The POPeRA method utilises the baseline radiographic score and patient-reported symptom duration to predict radiographic outcomes. It was applied at baseline, 2, and 5 years to patients with eRA from the randomised Finnish RA Combination trial (FIN-RACo) (n=144) and New Finnish RA Combination Therapy (NEO-RACo) (n=90) trials. For FIN-RACo, patients were randomised either to a single DMARD (sulfasalazine, with or without prednisolone) or to combination therapy (methotrexate+sulfasalazine+hydroxychloroquine, i.e. triple therapy, with prednisolone). In NEO-RACo, all patients were assigned intensified combination therapy (including 7.5 mg prednisolone/day) plus a randomised 6-month induction of either placebo or anti-TNF treatment (infliximab). RESULTS: In FIN-RACo, combination versus monotherapy resulted in superior outcomes in the change from predicted progression over 2 and 5 years (mean 35.7% reduction vs. -32.9%, a worsening from predicted, p=0.001; 34.2% vs. -17.8%, p=0.003, respectively). In NEO-RACo, combination+anti-TNF induction led to significantly greater reductions from predicted progression than combination+placebo, both at 2 and 5 years of follow-up (98.5% vs. 83.4%, p=0.005; 92.4% vs. 82.5%, p=0.027, respectively). Importantly, anti-TNF add-on led to superior reductions from predicted among RF-positive patients (2 years: 97.4% vs. 80.4%, p=0.009; 5 years: 90.2% vs. 80.1%, p=0.030), but not among RF-negative patients. CONCLUSIONS: These results confirm that conventional combination therapy in eRA has a long-term radiographic benefit versus monotherapy. Through POPeRA, it was made evident that anti-TNF induction therapy for 6 months further increases the long-term radiographic benefit of combination therapy in RF-positive patients.

RESUMEN

OBJECTIVE: To study whether adding initial infliximab to remission-targeted initial combination-DMARD treatment improves the long-term outcomes in patients with early rheumatoid arthritis (RA). METHODS: Ninety-nine patients with early, DMARD-naïve RA were treated with a triple combination of DMARDs, starting with methotrexate (max 25 mg/week), sulfasalazine (max 2 g/day), hydroxychloroquine (35 mg/kg/week), and with prednisolone (7.5 mg/day), and randomised to double blindly receive either infliximab (3 mg/kg; FIN-RACo+INFL) or placebo (FIN-RACo+PLA) infusions during the first 6 months. After 2 years the treatment strategies became unrestricted, but the treatment goal was strict ACR remission. At 5 years the clinical and radiographic outcomes were assessed. RESULTS: Ninety-one patients (92%) were followed up to 5 years, 45 in the FIN-RACo+INFL and 46 in the FIN-RACo+PLA groups. At 5 years, the respective proportions of patients in strict ACR and in disease activity score 28 remissions in the FIN-RACo+INFL and FIN-RACo+PLA groups were 60% (95% CI 44% to 74%) and 61% (95% CI 45% to 75%) (p=0.87), and 84% (95% CI 71% to 94%) and 89% (95% CI 76% to 96%) (p=0.51). The corresponding mean (SD) total Sharp/van der Heijde scores at 5 years were 4.3 (7.6), and 5.3 (7.3), while the respective mean Sharp/van der Heijde scores changes from baseline to 5 years were 1.6 (95% CI 0.0 to 3.4) and 3.7 (95% CI 2.2 to 5.8) (p=0.13). CONCLUSIONS: In early RA, targeted treatment with a combination of traditional DMARDs and prednisolone induces remission and minimises radiographic progression in most patients up to 5 years; adding initial infliximab for 6 months does not improve these outcomes.

RESUMEN

OBJECTIVES: To investigate long-term work disability of patients with early rheumatoid arthritis (RA) and to examine impact of early disease activity and radiological progression on the loss of final work capacity. METHODS: Work disability due to RA was studied over 15 years in 86 Finnish patients with early RA and available for the labour force at study entry. RA-related retirement was studied in relation to early disease activity defined as the 28-joint disease activity score area under curve (DAS28 AUC) during the first 12 months and the impact of early radiological progression from the baseline to year 1. RESULTS: The RA-related retirement rate was 7% after the first year, 11% after 2 years, 19% after 5 years, 33% after 10 years and 39% after 15 years. Of the patients with low disease activity (DAS28 AUC ≤3.2) none were retired during the first 3 years. The retirement rate was also lower in subsequent years (10% after 5 years, 14% after 10 years, and 27% after 15 years) among these patients compared to those with DAS28 AUC >3.2 (28%, 55%, and 64%, respectively). A similar trend was evident among patients with no radiological progression (≤1 unit increase in Larsen score) and those with >1 Larsen unit of progression during the first year of RA. CONCLUSIONS: Our study suggests that low disease activity and halting of radiological progression during the first year of the disease improve possibilities to maintain work capacity in RA during the subsequent 15 years.

RESUMEN

Oncolytic adenoviruses and certain chemotherapeutics can induce autophagy and immunogenic cancer cell death. We hypothesized that the combination of oncolytic adenovirus with low-dose temozolomide (TMZ) is safe, effective, and capable of inducing antitumor immune responses. Metronomic low-dose cyclophosphamide (CP) was added to selectively reduce regulatory T-cells. Preclinically, combination therapy inhibited tumor growth, increased autophagy, and triggered immunogenic cell death as indicated by elevated calreticulin, adenosine triphosphate (ATP) release, and nuclear protein high-mobility group box-1 (HMGB1) secretion. A total of 41 combination treatments given to 17 chemotherapy-refractory cancer patients were well tolerated. We observed anti- and proinflammatory cytokine release, evidence of virus replication, and induction of neutralizing antibodies. Tumor cells showed increased autophagy post-treatment. Release of HMGB1 into serum--a possible indicator of immune response--increased in 60% of treatments, and seemed to correlate with tumor-specific T-cell responses, observed in 10/15 cases overall (P = 0.0833). Evidence of antitumor efficacy was seen in 67% of evaluable treatments with a trend for increased survival over matched controls treated with virus only. In summary, the combination of oncolytic adenovirus with low-dose TMZ and metronomic CP increased tumor cell autophagy, elicited antitumor immune responses, and showed promising safety and efficacy.

RESUMEN

Psoriatic arthritis mutilans (PAM) is the rarest and most severe form of psoriatic arthritis, characterized by erosions of the small joints and osteolysis leading to joint disruption. Despite its severity, the underlying mechanisms are unknown, and no susceptibility genes have hitherto been identified. We aimed to investigate the genetic basis of PAM by performing massive parallel sequencing in sixty-one patients from the PAM Nordic cohort. We found rare variants in the NADPH oxidase 4 (NOX4) in four patients. In silico predictions show that the identified variants are potentially damaging. NOXs are the only enzymes producing reactive oxygen species (ROS). NOX4 is specifically involved in the differentiation of osteoclasts, the cells implicated in bone resorption. Functional follow-up studies using cell culture, zebrafish models, and measurement of ROS in patients uncovered that these NOX4 variants increase ROS levels both in vitro and in vivo. We propose NOX4 as the first candidate susceptibility gene for PAM. Our study links high levels of ROS caused by NOX4 variants to the development of PAM, offering a potential therapeutic target.

RESUMEN

OBJECTIVE: Early treatment of patients with rheumatoid arthritis (RA) with combination treatment starting with methotrexate, sulfasalazine, hydroxychloroquine and prednisolone (FIN-RACo strategy) is superior to monotherapy. A study was undertaken to determine whether infliximab (INFL) added to intensified FIN-RACo treatment for the initial 6 months improves the 2-year outcome. METHODS: 99 patients with early untreated active RA were enrolled in an investigator-initiated, randomised, double-blind, multicentre, parallel-group trial. Primary outcomes were remission and radiological changes at 2 years. All patients started with FIN-RACo. In addition, they were randomised to receive INFL or placebo (Pla) from weeks 4 to 26. RESULTS: At 24 months, 66% and 53%, respectively, of the patients in the FIN-RACo+INFL and FIN-RACo+Pla groups were in remission according to the modified American College of Rheumatology (ACR) criteria (p=0.19), 26% and 10% were in sustained modified ACR remission (p=0.042) and 82% in both groups were in remission by 28-joint disease activity score (not significant). Mean changes in the total Sharp-van der Heijde score were 0.2 and 1.4, respectively (p=0.0058). CONCLUSIONS: Most patients with early active RA achieve clinical remission and develop negligible joint damage with the intensified FIN-RACo regimen. Adding INFL for the first 6 months delays radiological progression.

RESUMEN

Twenty-five patients with chemotherapy refractory cancer were treated with a fully serotype 3-based oncolytic adenovirus Ad3-hTERT-E1A. In mice, Ad3 induced higher amounts of cytokines but less liver damage than Ad5 or Ad5/3. In humans, the only grade 3 adverse reactions were self-limiting cytopenias and generally the safety profile resembled Ad5-based oncolytic viruses. Patients that had been previously treated with Ad5 viruses presented longer lasting lymphocytopenia but no median increase in Ad3-specific T-cells in blood, suggesting immunological activity against antigens other than Ad3 hexon. Frequent alterations in antitumor T-cells in blood were seen regardless of previous virus exposure. Neutralizing antibodies against Ad3 increased in all patients, whereas Ad5 neutralizing antibodies remained stable. Treatment with Ad3-hTERT-E1A resulted in re-emergence of Ad5 viruses from previous treatments into blood and vice versa. Signs of possible efficacy were seen in 11/15 (73%) patients evaluable for tumor markers, four of which were treated only intravenously. Particularly promising results were seen in breast cancer patients and especially those receiving concomitant trastuzumab. Taken together, Ad3-hTERT-E1A seems safe for further clinical testing or development of armed versions. It offers an immunologically attractive alternative, with possible pharmacodynamic differences and a different receptor compared to Ad5.

RESUMEN

We recommend magnetic resonance imaging of the sacroiliac joints as the first line imaging method in suspected inflammatory back disorder. Plain X-ray can be taken from those over 35 years of age. A nonconclusive finding in plain X-ray should be verified by MR imaging. For the present, diagnostic criteria for spondylarthritis do not take into account spinal changes. Typical spinal findings can, however, be helpful in making treatment decisions. In case the spinal region MR imaging should be utilized if possible, because radiography is particularly insensitive for thoracic spine. After a confirmed diagnosis, the inflammatory nature of the condition can usually be assessed clinically.

RESUMEN

The safety of oncolytic viruses for treatment of cancer has been shown in clinical trials while antitumor efficacy has often remained modest. As expression of the coxsackie-adenovirus receptor may be variable in advanced tumors, we developed Ad5-D24-RGD, a p16/Rb pathway selective oncolytic adenovirus featuring RGD-4C modification of the fiber. This allows viral entry through alpha-v-beta integrins frequently highly expressed in advanced tumors. Advanced tumors are often immunosuppressive which results in lack of tumor eradication despite abnormal epitopes being present. Granulocyte-macrophage colony stimulating factor (GMCSF) is a potent activator of immune system with established antitumor properties. To stimulate antitumor immunity and break tumor associated immunotolerance, we constructed Ad5-RGD-D24-GMCSF, featuring GMCSF controlled by the adenoviral E3 promoter. Preliminary safety of Ad5-D24-RGD and Ad5-RGD-D24-GMCSF for treatment of human cancer was established. Treatments with Ad5-D24-RGD (N = 9) and Ad5-RGD-D24-GMCSF (N = 7) were well tolerated. Typical side effects were grade 1-2 fatigue, fever and injection site pain. 77% (10/13) of evaluable patients showed virus in circulation for at least 2 weeks. In 3 out of 6 evaluable patients, disease previously progressing stabilized after a single treatment with Ad5-RGD-D24-GMCSF. In addition, 2/3 patients had stabilization or reduction in tumor marker levels. All patients treated with Ad5-D24-RGD showed disease progression in radiological analysis, although 3/6 had temporary reduction or stabilization of marker levels. Induction of tumor and adenovirus specific immunity was demonstrated with ELISPOT in Ad5-RGD-D24-GMCSF treated patients. RGD modified oncolytic adenoviruses with or without GMCSF seem safe for further clinical development.

RESUMEN

Patients with advanced solid tumors refractory to and progressing after conventional therapies were treated with three different regimens of low-dose cyclophosphamide (CP) in combination with oncolytic adenovirus. CP was given with oral metronomic dosing (50 mg/day, N = 21), intravenously (single 1,000 mg dose, N = 7) or both (N = 7). Virus was injected intratumorally. Controls (N = 8) received virus without CP. Treatments were well tolerated and safe regardless of schedule. Antibody formation and virus replication were not affected by CP. Metronomic CP (oral and oral + intravenous schedules) decreased regulatory T cells (T(regs)) without compromising induction of antitumor or antiviral T-cell responses. Oncolytic adenovirus given together with metronomic CP increased cytotoxic T cells and induced Th1 type immunity on a systemic level in most patients. All CP regimens resulted in higher rates of disease control than virus only (all P < 0.0001) and the best progression-free (PFS) and overall survival (OS) was seen in the oral + intravenous group. One year PFS and OS were 53 and 42% (P = 0.0016 and P < 0.02 versus virus only), respectively, both which are unusually high for chemotherapy refractory patients. We conclude that low-dose CP results in immunological effects appealing for oncolytic virotherapy. While these first-in-human data suggest good safety, intriguing efficacy and extended survival, the results should be confirmed in a randomized trial.

RESUMEN

To associate specimens identified by molecular characters to other biological knowledge, we need reference sequences annotated by Linnaean taxonomy. In this study, we (1) report the creation of a comprehensive reference library of DNA barcodes for the arthropods of an entire country (Finland), (2) publish this library, and (3) deliver a new identification tool for insects and spiders, as based on this resource. The reference library contains mtDNA COI barcodes for 11,275 (43%) of 26,437 arthropod species known from Finland, including 10,811 (45%) of 23,956 insect species. To quantify the improvement in identification accuracy enabled by the current reference library, we ran 1000 Finnish insect and spider species through the Barcode of Life Data system (BOLD) identification engine. Of these, 91% were correctly assigned to a unique species when compared to the new reference library alone, 85% were correctly identified when compared to BOLD with the new material included, and 75% with the new material excluded. To capitalize on this resource, we used the new reference material to train a probabilistic taxonomic assignment tool, FinPROTAX, scoring high success. For the full-length barcode region, the accuracy of taxonomic assignments at the level of classes, orders, families, subfamilies, tribes, genera, and species reached 99.9%, 99.9%, 99.8%, 99.7%, 99.4%, 96.8%, and 88.5%, respectively. The FinBOL arthropod reference library and FinPROTAX are available through the Finnish Biodiversity Information Facility (www.laji.fi) at https://laji.fi/en/theme/protax. Overall, the FinBOL investment represents a massive capacity-transfer from the taxonomic community of Finland to all sectors of society.

RESUMEN

Oncolytic adenoviruses are an emerging treatment option for advanced and refractory cancer. Such patients are often treated with corticosteroids to ameliorate tumor associated symptoms. Thus, it is important to evaluate whether safety is affected by immunosuppression possibly induced by corticosteroids. Concurrent low-dose cyclophosphamide, appealing for its immunomodulatory effects, could also impact safety. In a retrospective case-control study, we evaluated the effect of systemic corticosteroid use in cancer patients receiving oncolytic virotherapy. Four treatment groups were identified: (1) oncolytic adenovirus with oral glucocorticoids, (2) virus alone, (3) virus with glucocorticoids and cyclophosphamide and (4) virus with cyclophosphamide. Adverse events, neutralizing antibody titers, viral DNA in circulation and tumor responses were evaluated. The most common adverse effects were grade 1-2 fatigue, nausea, fever and abdominal pain. Common asymptomatic findings included self-limiting grade 1-3 hyponatremia and aspartate aminotransferase increase. Safety was good and no significant differences were observed between the groups. All patients had an increase in neutralizing antibody titers post-treatment, and no trends for differences between groups were observed. There were fewer post-treatment virus genomes circulating in patients receiving glucocorticoids when compared to their control groups. Overall, glucocorticoid use in cancer patients receiving oncolytic adenovirus, with or without low-dose cyclophosphamide, seems safe.

RESUMEN

Augmenting antitumor immunity is a promising way to enhance the potency of oncolytic adenoviral therapy. Granulocyte-macrophage colony-stimulating factor (GMCSF) can mediate antitumor effects by recruiting natural killer cells and by induction of tumor-specific CD8(+) cytotoxic T-lymphocytes. Serotype 5 adenoviruses (Ad5) are commonly used in cancer gene therapy. However, expression of the coxsackie-adenovirus receptor is variable in many advanced tumors and preclinical data have demonstrated an advantage for replacing the Ad5 knob with the Ad3 knob. Here, a 5/3 capsid chimeric and p16-Rb pathway selective oncolytic adenovirus coding for GMCSF was engineered and tested preclinically. A total of 21 patients with advanced solid tumors refractory to standard therapies were then treated intratumorally and intravenously with Ad5/3-D24-GMCSF, which was combined with low-dose metronomic cyclophosphamide to reduce regulatory T cells. No severe adverse events occurred. Analysis of pretreatment samples of malignant pleural effusion and ascites confirmed the efficacy of Ad5/3-D24-GMCSF in transduction and cell killing. Evidence of biological activity of the virus was seen in 13/21 patients and 8/12 showed objective clinical benefit as evaluated by radiology with Response Evaluation Criteria In Solid Tumors (RECIST) criteria. Antiadenoviral and antitumoral immune responses were elicited after treatment. Thus, Ad5/3-D24-GMCSF seems safe in treating cancer patients and promising signs of efficacy were seen.

RESUMEN

Objective: Psoriatic arthritis mutilans (PAM) is the most severe phenotype of psoriatic arthritis due to excessive bone erosion causing joint destruction and decreased functional capacity. The aim of this study was to investigate the prevalence of comorbidities among patients with PAM and the association between comorbidities and joint involvement. Methods: A total of 66 patients aged ≥18 years from the Nordic countries with past or present psoriasis along with at least one mutilated joint were included in the present study. Results: The median number of comorbid conditions per patient was 1 [interquartile range (IQR) 0-2] and 16.7% reported three or more comorbidities. The most frequent comorbidity was hypertension (36.4%). The median number of mutilated joints per patient was 3 (IQR 1-8.3; range 1-38). Conclusion: Two thirds of the patients with PAM reported comorbid conditions and the most frequent was hypertension which affected more than a third of the patients. However, this study was unable to detect any association between comorbidities and the severity of PAM.

RESUMEN

BACKGROUND: Psoriatic arthritis mutilans (PAM) is the most severe phenotype of psoriatic arthritis (PsA). PURPOSE: To describe the radiological features in PAM and explore whether existing scoring systems for radiological damage in psoriatic arthritis are applicable for PAM. MATERIAL AND METHODS: Radiographs were scored according to the modified Sharp-van der Heijde (mSvdH) and the Psoriatic Arthritis Ratingen Score (PARS) systems for PsA. RESULTS: At inclusion, 55 PAM patients (49% women, mean age 58 ± 12 years) had conventional radiographs of both hands and feet. A total of 869 PAM joints were detected and 193 joints with ankylosis. The mean total mSvdH score was 213.7 ± 137.8 (41% of maximum) with a higher score for hands than for feet: 136.6 ± 90.1 vs. 79.1 ± 60.9. However, the total score was relatively higher in the feet than in the hands when compared to the highest possible scoring (47% vs. 38% of max). The mean total PARS score was 126.3 ± 79.6 (35% of max). Scoring for joint destruction was higher than for proliferation (22% vs. 11% of max). Strong correlation was found between mSvdH and PARS (r2 = 0.913). A significant correlation was found between scoring and duration of arthritis and the Health Assessment Questionnaire. History of smoking, BMI, and gender did not influence the scoring values. CONCLUSIONS: The two scoring systems studied may not be ideal to indicate progression of PAM in advanced disease since they reach ceiling effects rather early. Therefore, reporting early signs suggestive of PAM, e.g. signs of pencil-in-cup deformities or osteolysis, is crucial. This would reveal the presence of PAM and might lead to improved treatment in order to minimize joint damage.

RESUMEN

Objective: We investigated lipid concentrations, particle sizes and antibodies binding to periodontal bacteria Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis and to malondialdehyde-acetaldehyde (MAA) modified low-density lipoprotein in immunoglobulin (Ig) class A, G and M among patients with newly diagnosed rheumatoid arthritis (RA) in a population-based cohort.Methods: Concentrations and sizes of lipoprotein particles analysed by proton nuclear magnetic resonance spectroscopy and antibody levels to MAA modified low-density lipoprotein were studied at baseline and after one-year of follow-up. Serum Ig A and G class antibodies to periodontal bacteria were determined at baseline.Results: Sixty-three patients were divided into tertiles according to disease activity by disease activity score with 28 joint count and erythrocyte sedimentation rate (ESR) (<3.9, 3.9-4.7, >4.7). Small low-density lipoprotein concentration was lowest in the tertile with the highest disease activity. In high-density lipoprotein, the concentrations of total, medium and small particles decreased with disease activity. The particle size in low-density lipoprotein associated with disease activity and the presence of antibodies to P. gingivalis. Ig G and M antibodies to MAA modified low-density lipoprotein correlated with disease activity. Inflammation associated changes faded by one year.Conclusions: Drug naive RA patients had proatherogenic changes in lipid profiles, but they were reversible, when inflammation diminished.Key messagesPatients with drug naive rheumatoid arthritis showed proatherogenic lipid profiles.Reversible changes in lipid profiles can be achieved as response to inflammation suppression.Active therapy aimed at remission is essential in all patients with rheumatoid arthritis.

RESUMEN

OBJECTIVE: To evaluate the development of radiological changes of the cervical spine in patients with rheumatoid arthritis (RA) in the NEO-RACo trial treated with an intensive, remission-targeted combination of conventional synthetic disease-modifying antirheumatic drugs (csDMARD) and additional infliximab (IFX) or placebo (PLA) for the first 6 months. METHODS: Ninety-nine patients with early, DMARD-naive RA were treated with a triple combination of csDMARD and prednisolone, and randomized to double-blindly receive either IFX (FIN-RACo+IFX) or PLA (FIN-RACo+PLA) infusions during the first 6 months. After 2 years the treatment strategies became unrestricted, but the treatment goal was strict NEO-RACo remission. At the 10-year visit, radiographs of the cervical spine were taken of 85 patients (38 in the FIN-RACo+IFX group and 47 in the FIN-RACo+PLA group). The study was registered at ClinicalTrials.gov (NCT00908089). RESULTS: There were 4/85 patients (4.7%) with cervical spine involvement (CSI) by 10 years. Atlantoaxial subluxation was found in 2/85 patients (2.4%), both in the FIN-RACo+IFX group, and none in the FIN-RACo+PLA group. Atlantoaxial impaction was found in 1/85 patients (1.2%) in the FIN-RACo+IFX group. Subaxial subluxation was found in 1/85 patients (1.2%). CONCLUSION: Early and intensive remission-targeted treatment has reduced the incidence of CSI and our results show that intensive treatment also prevents its development in the long run.

RESUMEN

OBJECTIVE: The short-term outcomes of remission-targeted treatments of rheumatoid arthritis (RA) are well-established, but the long-term success of such strategies is speculative, as is the role of early add-on biologics. We assessed the 10-year outcomes of patients with early RA treated with initial remission-targeted triple combination of conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), 7.5-mg prednisolone, and additional infliximab (IFX) or placebo infusions. METHODS: Ninety-nine patients with early, DMARD-naive RA were treated with a triple combination of csDMARDs and prednisolone and randomized to double-blind receipt of infusions of either IFX (the Finnish Rheumatoid Arthritis Combination Therapy Trial [FIN-RACo] + IFX) or placebo (FIN-RACo + placebo) during the first 6 months. After 2 years, the treatment strategies became unrestricted, but the treatment goal was strict remission in the TNF-Blocking Therapy in Combination With Disease-Modifying Antirheumatic Drugs in Early Rheumatoid Arthritis (NEO-RACo) study. At 10 years, the clinical and radiographic outcomes and the drug treatments used between 5 and 10 years were assessed. RESULTS: Ninety patients (91%) were followed after 2 years, 43 in the FIN-RACo + IFX and 47 in the FIN-RACo + placebo group. At 10 years, the respective proportions of patients in strict NEO-RACo remission and in Disease Activity Score using 28 joints remission in the FIN-RACo + IFX and FIN-RACo + placebo groups were 46% and 38% (P = 0.46) and 82% and 72% (P = 0.29), respectively. The mean total Sharp/van der Heijde score was 9.8 in the FIN-RACo + IFX and 7.3 in the FIN-RACo + placebo group (P = 0.34). During the 10-year follow-up, 26% of the FIN-RACo + IFX group and 30% of the FIN-RACo + placebo group had received biologics (P = 0.74). CONCLUSION: In early RA, excellent results can be maintained up until 10 years in most patients treated with initial combination csDMARDs and remission-targeted strategy, regardless of initial IFX/placebo infusions.
