Better outcomes of COVID-19 in vaccinated compared to unvaccinated patients with systemic rheumatic diseases.

OBJECTIVE: Τo report outcomes of breakthrough COVID-19 in comparison with COVID-19 in unvaccinated patients with systemic rheumatic diseases (SRDs). METHODS: Patients with SRD with COVID-19 (vaccinated and unvaccinated) were included by their rheumatologists in a registry operated by the Greek Rheumatology Society in a voluntarily basis. Type, date and doses of SARS-CoV-2 vaccines were recorded, and demographics, type of SRD, concurrent treatment, comorbidities and COVID-19 outcomes (hospitalisation, need for oxygen supplementation and death) were compared between vaccinated and unvaccinated patients. RESULTS: Between 1 March 2020 and 31 August 2021, 195 patients with SRD with COVID-19 were included; 147 unvaccinated and 48 vaccinated with at least one dose of a SARS-CoV-2 vaccine (Pfizer n=38 or AstraZeneca n=10). Among vaccinated patients, 29 developed breakthrough COVID-19 >14 days after the second vaccine dose (fully vaccinated), while 19 between the first and <14 days after the second vaccine dose (partially vaccinated). Despite no differences in demographics, SRD type, treatment or comorbidities between unvaccinated and vaccinated patients, hospitalisation and mortality rates were higher in unvaccinated (29.3% and 4.1%, respectively) compared with partially vaccinated (21% and 0%) or fully vaccinated (10.3% and 0%) patients. CONCLUSIONS: Vaccinated patients with SRD with breakthrough COVID-19 have better outcomes compared with unvaccinated counterparts with similar disease/treatment characteristics.

SLICC-Frailty Index is independently associated with impaired physical function, activities of daily living and quality of life measures.

OBJECTIVE: The SLICC Frailty Index (SLICC-FI) was developed to assess health deficits including disease activity, organ damage, comorbidities and functional status. We examined any relationship between SLICC-FI and objective physical function measures, activities of daily living performance and quality of life in SLE. METHODS: SLICC-FI was estimated using data from patient files and patient-reported questionnaires. Jamar Dynamometer, pinch gauge and Purdue pegboard test measured grip strength, pinch strength and dexterity, respectively. Activities of daily living performance was assessed by the Disabilities of Arm, Shoulder and Hand (DASH) questionnaire and HAQ. Quality of life was evaluated by LupusQol questionnaire. RESULTS: This cross-sectional study included 240 SLE patients (90% female, mean (s.d.) age: 47.63 (13.01), median (IQR) disease duration: 9 (4-16)). Mean (s.d.) SLICC-FI was 0.09 (0.06). Forty-three (17.9%) patients were classified as robust, 105 (43.8%) as relatively less fit, 77 (32.1%) as least fit and 15 (6.2%) as frail. In univariate analysis, SLICC-FI was significantly associated with DASH and HAQ with an inverse association with grip strength, pinch strength and all purdue scores (all P < 0.001). A negative correlation was found between SLICC-FI score and all LupusQoL domain scores (all P < 0.001). All associations remained statistically significant in multivariate regression analysis, after adjustment for age, disease duration, SLEDAI-2K, SLICC, immunosuppressives, corticosteroids and Charlson score. CONCLUSION: SLICC-FI is independently associated with poor physical function and activities of daily living performance and impaired quality of life and may help to identify patients in need of additional interventions beyond routine care.

COVID-19 vaccine safety and nocebo-prone associated hesitancy in patients with systemic rheumatic diseases: a cross-sectional study.

OBJECTIVE: To describe the rate and type of adverse effects (AEs) and the frequency of disease flares after COVID-19 vaccination and to assess the reasons for vaccination hesitancy (non-vaccination) in SRD patients. METHODS: Telephone interviews were conducted of SRD patients consecutively enrolled (15/06/2021-1/7/2021). Participants were asked about the type of AEs and disease flare after vaccination. Reasons for vaccination hesitancy were recorded. Univariate and mutivariable analyses examined associations of demographic, clinical and other features, with occurrence of AEs, disease flare and non-vaccination. For the latter, association with negative vaccination behaviour (not influenza vaccinated for the last 2 years) and nocebo-prone behaviour (denoting AEs attributed to negative expectations [Q-No questionnaire]) was also tested. RESULTS: 561 out of 580 contacted patients were included in the study. 441/561 (78.6%) patients were vaccinated [90% (Pfizer, Moderna), 10% (Astra-Zeneca)]. AEs were reported by 148/441 (33.6%), with rates being comparable between the three vaccines. AEs were more common in females and those with chronic obstructive pulmonary disease [OR, 95% CI; females: 2.23 (1.30-3.83); COPD: 3.31 (1.24-8.83)]. Disease flare was reported in 9/441 (2%) patients. For those unvaccinated, fear that the vaccine would be harmful (53.3%), could cause disease flare (24.2%) and/or could cause thrombosis (21.7%) were the main reasons to do so. Multivariable analysis identified as independent variables for non-vaccination: nocebo-prone behaviour (OR; 95% CI, 3.88; 1.76-8.55), negative vaccination behaviour (6.56; 3.21-13.42) and previous COVID-19 infection (2.83; 1.13-7.05). Higher educational status was protective (0.49; 0.26-0.92). CONCLUSION: No new safety signals for COVID-19 vaccination were observed. Vaccination campaign should target SRD patients with nocebo-prone and negative influenza vaccination behaviour.

Increased influenza vaccination rates in patients with autoimmune rheumatic diseases during the Covid-19 pandemic: a cross-sectional study.

To assess non-compliance and potential changes in seasonal flu vaccination coverage before and during the Covid-19 pandemic in patients with autoimmune rheumatic diseases (ARDs). Consecutive patients with ARDs followed-up in 2 tertiary hospitals were telephone-interviewed (December 12-30, 2020) regarding seasonal flu vaccination during the 2019/20 and 2020/21 time periods. Self-reported disease flares that occurred after flu vaccination, as well as reasons for non-vaccination were recorded. One thousand fifteen patients were included. The rate of flu vaccination increased from 76% before to 83% during the COVID-19 pandemic (p = 0.0001). The rate of self-reported disease flares was < 1% among vaccinated patients. Reasons for not vaccination in both periods, respectively, included: 'was not recommended by their rheumatologists' (35.0vs.12.2%, p < 0.0001), 'did not feel that they would have any benefit' (36.9 vs. 32.6%), felt unsafe to do so (27.5 vs. 30.2%), or other reasons (18.9 vs. 23.8%). By multivariate analysis, age [OR = 1.03 (95% CI 1.02-1.04)] vs. [1.04 (95% CI 1.02-1.05)] and treatment with biologics [OR = 1.66 (95% CI 1.22-2.24) vs. [1.68 (95% CI 1.19-2.38)] were independent factors associated with vaccination in both periods. These findings, although are temporally encouraging, emphasize the need for continuous campaigns aiming at increasing patients' and physicians' awareness about the benefits of vaccination.

High 3-year golimumab survival in patients with rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis: real world data from 328 patients.

OBJECTIVES: Our primary objective was to study the long-term survival on drug (SOD) of patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ankylosing spondylitis (AS) treated with golimumab (GLM) in real life settings. METHODS: This was a retrospective, observational study of all patients treated with GLM in 4 Academic Centres in Greece during a 4-year period (09/2010-06/2014). SOD was analysed using Kaplan-Meier survival analysis, while Cox regression analysis estimating hazard ratios (HRs) for different baseline variables associated with drug discontinuation was performed for each disease. RESULTS: 328 patients (RA: 166, PsA: 82, AS: 80) were included. The estimated SOD at 2 and 3 years was 68% and 62% overall and was better for AS (79% and 76%) compared to RA (69% and 60%, p=0.067) and PsA (58% and 53%, p=0.001) patients; no difference was noted between RA and PsA patients (p=0.204). There was no difference in SOD between biologic-naïve and experienced nor between non-biologic co-treated or GLM monotherapy treated patients. Seropositivity (rheumatoid factor and/or anti-cyclic citrullinated peptide antibodies) was associated with a lower risk for GLM discontinuation by multivariate analysis (HR=0.5, 95% CI=0.0.25-1.1, p=0.05) in RA patients. During 606 patient-years of follow-up, 11 (3.3%) patients discontinued GLM due to adverse events (AE), accounting for 11% of treatment discontinuations. The rates of serious AEs and serious infections were 2.3 and 1.0/100-patient-years, respectively. CONCLUSIONS: In this real-life study, GLM showed a high 3-year SOD in patients with inflammatory arthritides with a low rate of discontinuation due to AEs.

Atherosclerosis is not accelerated in rheumatoid arthritis of low activity or remission, regardless of antirheumatic treatment modalities.

Objectives: RA associates with increased cardiovascular disease (CVD) morbidity and mortality due to accelerated atherosclerosis, attributed to both classical risk factors and chronic inflammation. The aim of this study was to test the hypothesis that effective disease control over 3 years modifies acceleration of atherosclerosis in RA. Methods: Consecutive, non-diabetic RA patients previously examined by ultrasonography for subclinical atherosclerosis were re-evaluated after 3.2 (0.2) years, provided that they were in remission/low disease activity (DAS28 <3.2) for at least 75% of this period. Patients (n = 139) were demographically matched with 139 non-diabetic, non-RA control individuals studied in parallel. Results: Patients and controls (mean age of 56 years at baseline) had a comparable burden of classical CVD risk factors. Patients' pulse wave velocity (reflecting arterial stiffness) changed by 0.07 m/s/year and left carotid intima-media thickness (reflecting wall hypertrophy) increased by 0.009 mm/year; formation of new atheromatic plaques in carotid and/or femoral arterial beds occurred in 22%. Multivariate analysis after correcting for all classical CVD risk factors and anti-hypertensive/lipid-lowering therapies demonstrated no significant differences between patients and controls in any of the subclinical atherosclerosis indices. Changes in all atherosclerosis indices from baseline to end of follow-up were comparable between those 56 patients treated with biologic DMARDs and their demographically matched patients treated with synthetic DMARDs. Conclusion: Effective disease control may abrogate any RA-specific effect on the progression of atherosclerosis regardless of treatment. Whether early and sustained RA control translates to the CVD outcomes expected in the general population should be examined in prospective studies.

Impact of biologic therapies on risk of adverse cardiovascular events in patients with Ankylosing Spondylitis or Psoriatic Arthritis: A systematic literature review.

BACKGROUND: Recent evidence highlights increased mortality and morbidity due to cardiovascular disease (CVD), especially within the two major forms of Spondyloarthropathies (SpAs), Ankylosing Spondylitis (AS) and Psoriatic Arthritis (PsA). Healthcare professionals and patients in these populations should be alerted regarding the high risk of cardiovascular (CV) events and thus, customize the treatment strategy accordingly. OBJECTIVE: This systematic literature review aimed to determine the effects of biological therapies on serious CV events in AS and PsA. METHODS: Screening for the study was carried out using PubMed and Scopus databases from the database's inception to the 17th of July 2021. The literature search strategy for this review is based on the Population, Intervention, Comparator, Outcomes (PICOs) framework. Randomized controlled trials (RCTs) of biologic therapies for the treatment of AS and/or PsA were included. The primary outcome measure was the number of serious CV events reported during the placebo-controlled phase. RESULTS: 4,422 articles were generated from keywords, eligibility criteria, and databases. Following the screening, we retained 13 studies for analysis: 3 in AS and 10 in PsA. Meta-analysis of results was not feasible due to the small number of the identified studies, the heterogeneity of the biologic treatment and the included populations, as well as the infrequently reported requested endpoint. According to our review, biologic treatments are safe options as for CV risk in patients with PsA or AS. CONCLUSION: Further and more extensive trials in AS/PsA patients at high risk of CV events are needed before firm conclusions can be drawn.

Omicron variant dominance and anti-SARS-CoV-2 vaccination are key determinants for a milder course of COVID-19 in patients with systemic autoimmune rheumatic diseases.

INTRODUCTION: This study aimed to determine whether the introduction of anti-SARS-CoV-2 vaccines and the dominance of the omicron variant had a significant impact on the outcome of COVID-19 in patients with systemic autoimmune rheumatic diseases (SAIRDs). METHODS: Using data entered to the Greek Rheumatology Society COVID-19 registry, we investigated the incidence of hospitalization and death due to COVID-19, during the successive periods of the pandemic according to the prevalent strain (wild-type, Alpha, Delta, Omicron) in vaccinated and unvaccinated patients. Variables independently associated with hospitalization and death were explored using multivariate regression analyses, while Kaplan-Meier curves were used to depict survival data. RESULTS: From August 2020 until June 30, 2022, 456 cases (70.2% females) of COVID-19 with a mean age (± SD) of 51.4 ± 14.0 years were reported. In unvaccinated patients, the proportions of hospitalization and death were 24.5% and 4%, compared to 12.5% and 0.8% in the vaccinated group (p < 0.001 for both comparisons). The rates of hospitalization for the wild-type, Alpha, Delta, and Omicron periods were 24.7%, 31.3%, 25.9%, and 8.1% respectively (p < 0.0001), while the case fatality rates were 2.7%, 4%, 7%, and 0%, respectively (p = 0.001). Using multivariable regression analysis, factors independently associated with hospitalization were infection by a non-Omicron variant, being non-vaccinated, exposure to rituximab, older age, and respiratory and cardiovascular disease. Independent predictors for death were contracting COVID-19 during the Alpha or Delta period, pulmonary disease, and older age, while being vaccinated was protective. CONCLUSIONS: In this 2-year analysis, the rates of hospitalization and death among patients with SAIRDs have declined significantly. Vaccination and the dominance of the Omicron variant appear to be the major determinants for this shift. Key points • During the late phase of the pandemic, the proportion of severe COVID-19 cases, defined as requiring hospitalization or resulting in death, in patients with systemic autoimmune rheumatic diseases has declined. • Anti-SARS-CoV-2 vaccination and the dominance of the Omicron strain are the key factors that have independently contributed to this shift.

Effectiveness and Safety of Certolizumab Pegol in Axial Spondyloarthritis in a Real-World Setting in Greece: A Sub-Analysis of the Prospective Non-Interventional CIMAX Cohort Study.

Objectives: We report the effectiveness and safety of certolizumab pegol (CZP) treatment in a real-world Greek axial spondyloarthritis (axSpA) population, including patients with radiographic (r-axSpA) and non-radiographic (nr-axSpA) disease. Methods: We performed a sub-analysis of the Greek cohort from CIMAX (NCT02354105), a multicentre, non-interventional cohort study that prospectively investigated CZP treatment in patients with axSpA. The primary outcome was change from baseline (CfB) in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) to Week 52. Results: Across 12 sites in Greece, 126 patients (r-axSpA: 91; nr-axSpA: 35) received ≥1 dose of CZP and were included in the Safety Set (SS), with 120 patients (r-axSpA: 86; nr-axSpA: 34) included in the Full Analysis Set (FAS). The mean (standard deviation [SD]) CfB in BASDAI at Week 52 was -3.8 (2.0) in the overall axSpA population, with numerically greater improvements observed for nr-axSpA patients compared with r-axSpA (nr-axSpA: -4.2 [2.1]; r-axSpA: -3.7 [2.0]). Improvements in the axSpA population, including r-axSpA and nr-axSpA subpopulations, were observed in key secondary and additional outcomes at Week 52. Overall, 14.3% (18/126) of patients in the axSpA population experienced ≥1 adverse event (AE). There were no serious AEs or deaths reported during the study. Conclusions: Patients with r-axSpA and nr-axSpA treated with CZP in clinical practice in Greece showed improvements in disease activity and key symptoms. CZP treatment may therefore help address the substantial health burden associated with axSpA in Greece.

A single infliximab infusion vs corticosteroids for acute panuveitis attacks in Behçet's disease: a comparative 4-week study.

OBJECTIVE: To compare a single infusion of the anti-TNF antibody infliximab vs CSs for acute panuveitis attacks in Behçet's disease (BD). METHODS: A prospective, observational study of patients with panuveitis, who received either an infliximab infusion (5 mg/kg, 19 eyes) or high-dose methylprednisolone intravenously (1 g/day for 3 days, 8 eyes), or intra-vitreal triamcinolone acetonide (4 mg, 8 eyes) at attack's onset. Baseline maintenance therapy remained unchanged during the following 30 days. Visual acuity, anterior chamber cells, vitreous cells and inflammation of the posterior eye segment were assessed at baseline and at Days 1, 7, 14 and 29 (±1) post-treatment. RESULTS: While no significant differences were noted between i.v. and intra-vitreal CSs, infliximab was faster than CSs in decreasing total ocular inflammation scores and fundus inflammation scores (P = 0.01 and P < 0.0001 for treatment × time(2) interaction, respectively, using generalized estimating equation analysis). Independently of time, infliximab was superior to CSs in clearing retinal vasculitis (P < 0.003), as well as in resolution of retinitis (P = 0.008) and cystoid macular oedema (P < 0.007). Moreover, a faster regression of cystoid macular oedema was observed with infliximab compared with CSs (P < 0.03). The beneficial effects of the three treatment modalities on visual acuity were comparable from baseline to the end of follow-up. No side effects were noted with infliximab or methylprednisolone, whereas intra-vitreal triamcinolone acetonide caused ocular hypertension in four of the eight eyes, requiring surgical intervention in two. CONCLUSION: A single infusion of infliximab should always be considered, even as an adjunct therapy, for the control of acute panuveitis attacks in BD.

Early effects of IL-6 receptor inhibition on bone homeostasis: a pilot study in women with rheumatoid arthritis.

OBJECTIVES: A critical role of interleukin-6 (IL-6) in bone homeostasis has been suggested in experimental studies. We examined whether inhibition of IL-6 receptor in patients with rheumatoid arthritis (RA) results in early alterations of circulating markers of bone remodelling. METHODS: Circulating levels of osteoprotegerin, receptor activator of nuclear factor-kappaB ligand (RANKL), Wnt signalling pathway inhibitors Dickkopf-1 (Dkk-1) and sclerostin, markers of bone resorption (C-terminal cross-linking telopeptide of collagen type-I (CTX), tartrate-resistant acid phosphatase isoform-5b) and bone formation (bone-specific alkaline-phosphatase, osteocalcin) were examined in 22 women with active RA before and after two monthly infusions of tocilizumab (8mg/kg each); 'healthy', non-osteopenic, 1:1 age-matched women served as controls. RESULTS: At baseline, osteoprotegerin/RANKL ratio in patients was lower than controls by 5-fold; circulating osteoprotegerin correlated negatively with corresponding 28-joint-count disease activity scores and circulating RANKL correlated positively with C-reactive protein. Also, Dkk-1, sclerostin, CTX and osteocalcin levels were higher in RA than controls. After two months, osteoprotegerin/RANKL ratio increased, Dkk-1 decreased and sclerostin increased comparing to baseline; other markers did not change significantly. Increases of osteoprotegerin/RANKL ratio were more prominent in 10 patients who achieved remission or low disease activity after tocilizumab than in 12 patients who did not. In contrast, the significant alterations of both Wnt inhibitors were comparable between these patient subgroups. CONCLUSIONS: Anti-IL-6 therapy induced suppression of the inflammatory response affects rapidly the disrupted bone homeostasis in active RA. An additional, possibly specific, effect of IL-6 receptor inhibition on bone remodelling in humans should be further examined.

Introduction and switching of biologic agents are associated with antidepressant and anxiolytic medication use: data on 42 815 real-world patients with inflammatory rheumatic disease.

OBJECTIVES: Depression and anxiety are linked bi-directionally with inflammatory rheumatic diseases (IRDs) activity, which in turn, depends on subjective patient reported outcomes that can be distorted by comorbid mood disorders. We tested the hypothesis that introduction and/or switching of biologic agents for IRDs are associated with treatment for depression and/or anxiety, by analysing real-world data. METHODS: Using a country-wide electronic prescription database (10 012 604 registered, 99% population coverage), we captured almost all patients with rheumatoid arthritis (n=12 002), psoriatic arthritis (n=5465) and ankylosing spondylitis (n=6423) who received biologic disease modifying anti-rheumatic drugs (bDMARDs) during a 2-year period (8/2016-7/2018). Concomitant antidepressant/anxiolytic medication use was documented in patients who started or switched bDMARDs and compared with those who remained on conventional synthetic (cs)DMARDs or the same bDMARD, respectively, by multivariate regression analysis. RESULTS: Two-year data analysis on 42 815 patients revealed that bDMARD introduction was associated with both antidepressant [OR: 1.248, 95% CI 1.153 to 1.350, p<0.0001] and anxiolytic medication use [OR: 1.178, 95% CI 1.099 to 1.263, p<0.0001]. Moreover, bDMARD switching was also associated with antidepressant [OR: 1.502, 95% CI 1.370 to 1.646, p<0.0001] and anxiolytic medication use [OR: 1.161, 95% CI 1.067 to 1.264, p=0.001]. Notably, all these associations were independent of age, gender, underlying disease diagnosis and concomitant glucocorticoid or csDMARD medication use. CONCLUSION: In real-world settings, both introduction and switching of bDMARDs in patients with IRDs were associated with the presence of mood disorders. Although a causal relationship is uncertain, the impact of depression and anxiety should always be considered by physicians facing the decision to introduce or switch bDMARDs in patients with active IRDs.

Nocebo-Prone Behaviour in Patients with Autoimmune Rheumatic Diseases during the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic is associated with emotional distress and significant disruptions in health-care services. These are key players in the development of nocebo phenomena. We aimed to investigate nocebo-prone behaviour in patients with autoimmune rheumatic diseases (ARD) amid the COVID-19 pandemic-associated lockdown. METHODS: Consecutive patients were telephone-interviewed during the COVID-19 pandemic in Greece. Clinical and socioeconomic characteristics (eg, level of education) were recorded. For nocebo behaviour, a four-item validated questionnaire (Q-No, cut-off score>15), was used. Results were compared with pre-COVID-19 Q-No scores collected from patients followed-up in our department. RESULTS: Nocebo behaviour was detected in 51/500 (10.2%) individuals. In patients with nocebo behaviour, use of anti-hypertensives was less common (17.6% vs 31.8%, p=0.04), but a higher level of education was more common (58.8% vs 35.9%, p=0.002), compared with patients with Q-No score ≤15; the latter retained statistical significance in multivariate regression analysis (p=0.009, OR [95%CI]: 2.29, [1.23-4.25]). Total Q-No scores were higher in the COVID-19-period compared to the pre-COVID-19 era [median (range); 12 (4-20) vs 11 (4-20), p=0.02]. Among 78 patients with available Q-No questionnaires in the pre-COVID-19 era, 11 (14.1%) displayed nocebo behaviour, which increased to 16 (20.5%) amid the COVID-19 pandemic. Interim development of nocebo behaviour was also associated with higher educational level (p=0.049, OR: 3.65, 95%CI: 1.005-13.268). CONCLUSION: A considerable proportion of ARD patients manifested nocebo-prone behaviour during the COVID-19 pandemic, which was more common among those with high educational level.

Predictors of morbidity and mortality in early systemic sclerosis: Long-term follow-up data from a single-centre inception cohort.

OBJECTIVES: To determine predictors of morbidity and mortality in systemic sclerosis (SSc) in a long-term follow-up of an inception cohort of early SSc patients. METHODS: We evaluated clinical manifestations, laboratory and lung function tests at disease onset as predictors of morbidity and mortality in 3rd, 6th and 9th year in SSc patients recruited within 12 months of disease onset. RESULTS: A total of 115 SSc patients (97 women, mean age 48.1 ±â€¯13.5 years, 54 diffuse subtype) were included. In multivariate regression analysis, predictors at disease onset for the presence of pulmonary fibrosis in 6th year of follow-up were diffuse subtype (OR: 4.4, p = 0.033), digital ulcers (OR: 7.9, p = 0.014) and esophageal involvement (OR: 4.79, p = 0.038). Arrythmias at disease onset predicted pulmonary hypertension (OR: 6.05, p = 0.022), while age (OR: 1.12, p = 0.002) and anti-Scl70 (OR: 4.3, p = 0.038) predicted arrhythmias in 6th year. During a follow-up of 101.8 ±â€¯48.5 months, 23/115 patients died. Cox proportional hazard models analysis revealed 6 independent predictors of mortality present at disease onset: age at disease onset (45-59 years (HR: 3.0, p = 0.098), ≥60 years (HR: 4.3, p = 0.073), male gender (HR: 3.63, p = 0.025), diffuse subtype (HR: 2.83, p = 0.095), pulmonary fibrosis (HR: 3.7, p = 0.032), echocardiography-diagnosed pulmonary hypertension (HR = 7.49, p = 0.008) and DLCO < 60% (HR: 3.17, p = 0.035). Mortality rates at 3 and 6 years were 14% and 24% for patients with 3 independent predictors and 46% and 53% for patients with 4-6 predictors, respectively. CONCLUSION: Clinical phenotypes at disease onset may predict morbidity and mortality in SSc and guide treatment decisions.

Brief Report: Drug-Free Long-Term Remission in Severe Behçet's Disease Following Withdrawal of Successful Anti-Tumor Necrosis Factor Treatment.

OBJECTIVE: To test the hypothesis that remission of Behçet's disease (BD) in patients with severe vital organ involvement is maintained after withdrawal of successful anti-tumor necrosis factor (anti-TNF) treatment. METHODS: This single-center, retrospective, longitudinal outcomes study focused on consecutive patients with disease refractory to treatment with conventional immunosuppressant agents who responded to add-on long-term anti-TNF treatment that was subsequently discontinued. The end point was the proportion of patients remaining in complete remission for at least 3 years after withdrawal of anti-TNF treatment. RESULTS: In our BD cohort comprising 87 patients, 29 were eligible for analysis. All of these patients had disease that was refractory to conventional immunosuppressive therapy and had received successful anti-TNF treatment for a median of 2 years (interquartile range [IQR] 1.1-2.0) before treatment discontinuation. Of these patients, 12 (41%) achieved the study end point. The remaining 17 patients experienced a relapse within 1 year (IQR 0.6-1.5) after discontinuation. Re-treatment with anti-TNF was safe and effective in 14 (82%) of 17 patients; so far, 4 of these patients also achieved the study end point. Overall, 16 patients have remained in complete remission (median 6.5 years [IQR 5.5-8]). Ten of these patients are in drug-free remission (treated with anti-TNF agents, mainly for sight-threatening disease), and 6 are in azathioprine-maintained remission (treated with anti-TNF agents for ocular, intestinal, or central nervous system involvement). Notably, patients in drug-free remission were significantly younger and had a significantly shorter duration of BD when anti-TNF treatment was initiated compared to patients receiving azathioprine maintenance treatment. CONCLUSION: Drug-free, long-term remission after withdrawal of successful anti-TNF treatment is feasible in patients with severe BD. Because an anti-TNF agent-induced "cure" cannot be differentiated from spontaneous remission by natural history, prospective studies should examine whether anti-TNF agents should be used as first-line treatment for the induction of remission in every patient with vital organ involvement.

Anti-TNFα treatment for recalcitrant ulcerative necrobiosis lipoidica diabeticorum: A case report and review of the literature.

INTRODUCTION: Necrobiosis lipoidica diabeticorum (NLD) is a rare degenerative connective tissue disorder associated with diabetes mellitus, which usually presents with red papules or plaques with raised edges and occasional ulceration. Ulcerating NLD is notoriously difficult to treat. We present a young patient with ulcerative NLD who was successfully treated with the anti-TNFα agent infliximab. Case presentation is followed by a review of therapeutic TNFα blockade in NLD. CASE PRESENTATION: A 17-year old woman with type 1 diabetes since the age of 8, presented with a long-standing and extensively ulcerated and infected NLD lesion on her left shin. After achieving better glycemic control and treating her for infection of the wound, several NLD treatments failed to help, including corticosteroids and hyperbaric oxygen. She was treated successfully with 4 monthly sessions of 5mg/kg body weight intravenous infliximab, achieving complete resolution of ulceration. DISCUSSION: A multitude of available treatments have been suggested for NLD over the past decades, based on two axes, one through wound healing and the other through immunosuppression. Anti-TNFα agents are relatively new drugs that brought a revolution in chronic inflammatory diseases and have been on the rise as novel potential treatments for NLD. Three out of the five available anti-TNFα agents have been safely tested so far, both topically and systematically, with mostly favorable results. CONCLUSION: Intravenous infliximab was successful in the treatment of recalcitrant ulcerating NLD in our patient. Taken together with an increasing number of similar reports revealing a pathogenetic role of TNFα in NLD, we suggest that anti-TNFα agents are promising drugs in the management of this condition.
