Tocilizumab in giant cell arteritis: Multicenter open-label study of 22 patients

OBJECTIVE To assess the efficacy of tocilizumab (TCZ) in giant cell arteritis (GCA) patients with refractory disease and/or with unacceptable side effects due to corticosteroids. METHODS A retrospective multicenter open-label study on 22 GCA patients treated with TCZ at standard dose of 8mg/kg/month. The main outcomes were achievement of disease remission and reduction of corticosteroid dose. RESULTS The mean age ± standard deviation of patients was 69 ± 8 years. The main clinical features at TCZ onset were polymyalgia rheumatica (n = 16), asthenia (n = 7), headache (n =5), constitutional symptoms (n = 4), jaw claudication (n = 2), and visual loss (n = 2). Besides corticosteroids and before TCZ onset, 19 of 22 patients had also received several conventional immunosuppressive and/or biologic drugs. Of 22 patients, 19 achieved rapid and maintained clinical improvement following TCZ therapy. Also, after a median follow-up of 9 (interquartile range: 6-19) months, the C-reactive protein level had fallen from 1.9 (1.2-5.4) to 0.2 (0.1-0.9)mg/dL (p < 0.0001) and the erythrocyte sedimentation rate decreased from 44 (20-81) to 12 (2-20)mm/1st hour (p = 0.001). The median dose of prednisone was also tapered from 18.75 (10-45) to 5 (2.5-10)mg/day (p < 0.0001). However, TCZ had to be discontinued in 3 patients due to severe neutropenia, recurrent pneumonia, and cytomegalovirus infection. Moreover, 1 patient died after the second infusion of TCZ due to a stroke in the setting of an infectious endocarditis. CONCLUSION TCZ therapy leads to rapid and maintained improvement in patients with refractory GCA and/or with unacceptable side effects related to corticosteroids. However, the risk of infection should be kept in mind when using this drug in patients with GCA.

Efficacy of Tocilizumab in Conventional Treatment–Refractory Adult-Onset Still's Disease: Multicenter Retrospective Open-Label Study of Thirty-Four Patients†

Adult‐onset Stills disease (AOSD) is frequently refractory to standard therapy. Tocilizumab (TCZ) has demonstrated efficacy in single cases and in small series of patients with AOSD. The aim of this multicenter study was to assess the efficacy of TCZ in patients with AOSD refractory to conventional treatment.

Efficacy of Anakinra in Refractory Adult-Onset Still's Disease: Multicenter Study of 41 Patients and Literature Review.

AbstractAdult-onset Stills disease (AOSD) is often refractory to standard therapy. Anakinra (ANK), an interleukin-1 receptor antagonist, has demonstrated efficacy in single cases and small series of AOSD. We assessed the efficacy of ANK in a series of AOSD patients.Multicenter retrospective open-label study. ANK was used due to lack of efficacy to standard synthetic immunosuppressive drugs and in some cases also to at least 1 biologic agent.Forty-one patients (26 women/15 men) were recruited. They had a mean age of 34.4 ± 14 years and a median [interquartile range (IQR)] AOSD duration of 3.5 [2–6] years before ANK onset. At that time the most common clinical features were joint manifestations 87.8%, fever 78%, and cutaneous rash 58.5%. ANK yielded rapid and maintained clinical and laboratory improvement. After 1 year of therapy, the frequency of joint and cutaneous manifestations had decreased to 41.5% and to 7.3% respectively, fever from 78% to 14.6%, anemia from 56.1% to 9.8%, and lymphadenopathy from 26.8% to 4.9%. A dramatic improvement of laboratory parameters was also achieved. The median [IQR] prednisone dose was also reduced from 20 [11.3–47.5] mg/day at ANK onset to 5 [0–10] at 12 months. After a median [IQR] follow-up of 16 [5–50] months, the most important side effects were cutaneous manifestations (n = 8), mild leukopenia (n = 3), myopathy (n = 1), and infections (n = 5).ANK is associated with rapid and maintained clinical and laboratory improvement, even in nonresponders to other biologic agents. However, joint manifestations are more refractory than the systemic manifestations.

Anti-TNF-α therapy in refractory uveitis associated with sarcoidosis: Multicenter study of 17 patients

OBJECTIVES To assess anti-TNF-α therapy response in uveitis associated with sarcoidosis refractory to conventional immunosuppressive therapy. METHODS Open-label, multicenter, retrospective study on patients with sarcoid uveitis who underwent anti-TNF-α therapy because of inadequate response to conventional therapy including corticosteroids and at least 1 systemic synthetic immunosuppressive drug. The main outcome measurements were degree of anterior and posterior chamber inflammation, visual acuity, macular thickness, and immunosuppression load. RESULTS A total of 17 patients (8 men; 29 affected eyes; mean ± standard deviation age 38.4 ± 16.8; range: 13-76 years) were studied. The patients had bilateral hilar lymphadenopathy (58.8%), lung parenchyma involvement (47.1%), peripheral lymph nodes (41.2%), and involvement of other organs (52.9%). Angiotensin-converting enzyme was elevated in 58.8%. The most frequent ocular pattern was bilateral chronic relapsing panuveitis. The first biologic agent used was adalimumab in 10 (58.8%) and infliximab in 7 (41.2%) cases. Infliximab 5mg/kg intravenously every 4-8 weeks and adalimumab 40mg subcutaneously every 2 weeks were the most common administration patterns. In most cases anti-TNF-α therapy was given in combination with immunosuppressive drugs. The mean duration of follow-up was 33.9 ± 17.1 months. Significant improvement was observed following anti-TNF-α therapy. Baseline results versus results at 2 years from the onset of biologic therapy were the following: the median of cells in the ocular anterior chamber (interquartile range-IQR) 0.5 (0-2) versus 0 (0-0) (p = 0.003), vitritis 0 (0-1.25) versus 0 (0-0) (p = 0.008), macular thickness (391.1 ± 58.8 versus 247 ± 40.5µm) (p = 0.028), and visual acuity 0.60 ± 0.33 versus 0.74 ± 0.27; p = 0.009. The median daily (interquartile range) dose of prednisone was also reduced from 10 (0-30)mg at the onset of the anti-TNF-α therapy to 0 (0-0)mg at 2 years (p = 0.02). Significant reduction was also achieved in the immunosuppressive load. CONCLUSION Anti-TNF-α therapy is effective in sarcoid uveitis patients refractory to conventional immunosuppressive therapy. Infliximab and adalimumab allowed a substantial reduction in prednisone dose despite having failed standard therapy.

Anti-tumor necrosis factor-alpha therapy improves endothelial function and arterial stiffness in patients with moderate to severe psoriasis: A 6-month prospective study.

The aim of the present study was to determine if the use of the anti‐tumor necrosis factor (TNF)‐α monoclonal antibody adalimumab could improve endothelial function and arterial stiffness in patients with moderate to severe psoriasis. This was a prospective study on a series of consecutive patients with moderate to severe psoriasis who completed 6 months of therapy with adalimumab. Patients with history of cardiovascular events, diabetes mellitus, kidney disease, hypertension or body mass index of 35 kg/m2 or more were excluded. Assessment of endothelial function by brachial artery reactivity measuring flow‐mediated endothelial dependent vasodilatation (FMD%), and carotid arterial stiffness by pulse wave velocity (PWV) was performed at the onset of treatment (time 0) and at month 6. Twenty‐nine patients were studied. Anti‐TNF‐α adalimumab therapy yielded a significant improvement of endothelial function. The mean ± standard deviation (SD) FMD% values increased from 6.19 ± 2.44% at the onset of adalimumab to 7.46 ± 2.43% after 6 months of treatment with this biologic agent (P = 0.008). Likewise, following the use of adalimumab, PWV levels decreased from 6.28 ± 1.04 m/s at the onset of adalimumab to 5.69 ± 1.31 m/s at 6 months (P = 0.03). In conclusion, patients with moderate to severe psoriasis exhibit improvement of endothelial function and arterial stiffness following anti‐TNF‐α therapy. These findings are of potential relevance due to increased risk of cardiovascular disease in patients with severe psoriasis.

Carotid artery plaque in women with rheumatoid arthritis and low estimated cardiovascular disease risk: a cross-sectional study

IntroductionWe previously reported that most patients with rheumatoid arthritis (RA) and moderate cardiovascular disease (CVD) risk according to the Systematic COronary Evaluation score (SCORE) experience carotid artery plaque. In this study, we aimed to identify patient characteristics that can potentially predict carotid plaque presence in women with RA and a concurrent low CVD risk according to the SCORE.MethodsA cohort of 144 women with an evaluated low risk of CVD (SCORE value of zero) was assembled amongst 550 consecutive patients with RA that underwent CVD risk factor recording and carotid artery ultrasound. Participants had no established CVD, moderate or severe chronic kidney disease, or diabetes. We assessed carotid plaque(s) presence and its associated patient characteristics.ResultsCarotid artery plaque was present in 35 (24.3%) of women with RA. Age, the number of synthetic disease-modifying agents (DMARDs) and total cholesterol concentrations were independently associated with plaque in multivariable stepwise backward regression analysis (odds ratio (95% confidence interval) = 1.15 (1.07 to 1.24), P <0.0001, 1.51 (1.05 to 2.17), P = 0.03 and 1.66 (1.00 to 2.73) P = 0.04), respectively). The area under the curve (AUC) of the receiver operating curve (ROC) for the association with plaque was 0.807 (P <0.0001), 0.679 (P = 0.001) and 0.599 (P = 0.08) for age, total cholesterol concentrations and number of synthetic DMARDs used, respectively. The optimal cutoff value in predicting plaque presence for age was 49.5 years with a sensitivity and specificity of 74% and 75%, respectively, and for total cholesterol concentration, it was 5.4 mmol/l with a sensitivity and specificity of 63% and 70%, respectively. The plaque prevalence was 37.5% in patients (n = 80; 55.6%) with age >49.5 years or/and total cholesterol concentration of >5.4 mmol/l, respectively, compared to only 7.8% in those (n = 64; 44.4%) with age ≤49.5 years or/and total cholesterol concentration of ≤5.4 mmol/l, respectively.ConclusionsApproximately one-third of women with RA who experience a low SCORE value and are aged >49.5 years or/and have a total cholesterol concentration of >5.4 mmol/l, experience high-risk atherosclerosis, which requires intensive CVD risk management.

Adipokines, Biomarkers of Endothelial Activation, and Metabolic Syndrome in Patients with Ankylosing Spondylitis

Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease associated with accelerated atherosclerosis and increased risk of cardiovascular (CV) disease. AS patients also display a high prevalence of features clustered under the name of metabolic syndrome (MeS). Anti-TNF-α therapy was found to be effective to treat AS patients by suppressing inflammation and also improving endothelial function. Previously, it was demonstrated that a short infusion of anti-TNF-α monoclonal antibodyinfliximab induced a rapid and dramatic reduction in serum insulin levels and insulin resistance along with a rapid improvement of insulin sensitivity in nondiabetic AS patients. The role of adipokines, MeS-related biomarkers and biomarkers of endothelial cell activation and inflammation seem to be relevant in different chronic inflammatory diseases. However, its implication in AS has not been fully established. Therefore, in this review we summarize the recent advances in the study of the involvement of these molecules in CV disease or MeS in AS. The assessment of adipokines and biomarkers of endothelial cell activation and MeS may be of potential relevance in the stratification of the CV risk of patients with AS.

HLA-DRB1 association with Henoch-Schonlein purpura

Objective: Henoch-Schönlein purpura (HSP) is the most common vasculitis in children but it is not exceptional in adults. Increased familial occurrence supports a genetic predisposition for HSP. In this context, an association with the human leukocyte antigen-HLA-DRB1*01 phenotype has been suggested in Caucasian individuals with HSP. However, data on the potential association of HSP with HLA-DRB1*01 were based on small case series. To further investigate this issue, we performed HLA-DRB1 genotyping of the largest series of HSP patients ever assessed for genetic studies in Caucasians. Methods: 342 Spanish patients diagnosed with HSP fulfilling the American College of Rheumatology and the Michel et al classification criteria, and 303 sex and ethnically matched controls were assessed. HLA-DRB1 alleles were determined using a PCR-Sequence-Specific-Oligonucleotide Probe (PCR-SSOP) method. Results: A statistically significant increase of HLA-DRB1*01 in HSP patients when compared with controls was found (43% vs 7%, respectively; p<0.001; odds ratio-OR=2.03 [1.43-2.87]). It was due to the increased frequency of HLA-DRB1*0103 phenotype in HSP (14% vs 2%; p<0.001; OR=8.27 [3.46-23.9]). These results remained statistically significant after adjusting for Bonferroni correction. In contrast, a statistically significant decreased frequency of the HLA-DRB1*0301 phenotype was observed in patients compared to controls (5.6% vs 18.1%, respectively; p<0.001, OR=0.26 [0.14-0.47]), even after adjustment for Bonferroni correction. No HLA-DRB1 association with specific features of the disease was found. Conclusion: Our study confirms an association of HSP with HLA-DRB1*01 in Caucasians. Also, a protective effect against the development of HSP appears to exist in Caucasians carrying the HLA-DRB1*03 phenotype. This article is protected by copyright.

Increased familial occurrence supports a genetic predisposition to IgAV. In this context, an association with the HLA–DRB1*01 phenotype has been suggested in Caucasian individuals with IgAV. However, data on the potential association of IgAV with HLA–DRB1*01 were based on small case series. We undertook this study to further investigate this potential association by performing HLA–DRB1 genotyping in the largest series of IgAV patients ever assessed for genetic studies in Caucasians.

Lack of Association between ABO, PPAP2B, ADAMST7, PIK3CG, and EDNRA and Carotid Intima-Media Thickness, Carotid Plaques, and Cardiovascular Disease in Patients with Rheumatoid Arthritis

Introduction. Rheumatoid arthritis (RA) is a polygenic disease associated with accelerated atherosclerosis and increased cardiovascular (CV) mortality. Recent studies have identified the ABO rs579459, PPAP2B rs17114036, and ADAMTS7 rs3825807 polymorphisms as genetic variants associated with coronary artery disease and the PIK3CG rs17398575 and EDNRA rs1878406 polymorphisms as the most significant signals related to the presence of carotid plaque in nonrheumatic Caucasian individuals. Accordingly, we evaluated the potential relationship between these 5 polymorphisms and subclinical atherosclerosis (assessed by carotid intima-media thickness (cIMT) and presence/absence of carotid plaques) and CV disease in RA. Material and Methods. 2140 Spanish RA patients were genotyped for the 5 polymorphisms by TaqMan assays. Subclinical atherosclerosis was evaluated in 620 of these patients by carotid ultrasonography technology. Results. No statistically significant differences were found when each polymorphism was assessed according to cIMT values and presence/absence of carotid plaques in RA, after adjusting the results for potential confounders. Moreover, no significant differences were obtained when RA patients were stratified according to the presence/absence of CV disease after adjusting for potential confounders. Conclusion. Our results do not confirm association between ABO rs579459, PPAP2B rs17114036, ADAMTS7 rs3825807, PIK3CG rs17398575, and EDNRA rs1878406 and subclinical atherosclerosis and CV disease in RA.

Clinical follow-up predictors of disease pattern change in anti-Jo1 positive anti-synthetase syndrome: Results from a multicenter, international and retrospective study

OBJECTIVE Arthritis, myositis and interstitial lung disease (ILD) constitute the classic clinical triad of anti-synthetase syndrome (ASSD). These patients experience other accompanying features, such as Raynauds phenomenon, fever or mechanics hands. Most ASSD patients develop the complete triad during the follow-up. In the present study we aimed to determine whether the subsequent appearance of accompanying features may suggest the development of triad findings lacking at the onset in anti-Jo1 positive ASSD patients. METHODS Anti-Jo1 positive patients presenting with incomplete ASSD (no >2 classic triad features) were assessed. Clinical characteristics and clusters of disease manifestations were retrospectively collected and analyzed in a large international multicenter cohort of ASSD patients. RESULTS 165 patients (123 women) with incomplete ASSD were identified. Ninety-five patients (57.5%) developed new classic triad manifestations after 15months median (IQR 9-51) and 40 (24%) developed new accompanying features after 19months median (IQR 6-56) from disease onset. During the follow-up, the ex-novo occurrence of triad features was observed in 32 out of 40 patients (80%) with new accompanying findings and in 63 out of 125 patients (50.5%) without new accompanying findings (p=0.002). In patients with at least one new accompanying feature the odds ratio for the occurrence of new triad manifestations was 3.94 with respect to patients not developing ex-novo accompanying findings (95% CI 1.68-9.21, p=0.002). CONCLUSION Anti-Jo1 ASSD patients with incomplete forms at disease onset are at high risk for the subsequent occurrence of lacking classic triad findings. Although all ASSD patients should be carefully assessed for the occurrence of new triad features, a closer follow-up should be considered in the subgroup of patients developing ex novo accompanying findings. These patients, indeed, have near four-fold increased risk for new classic triad manifestation occurrence with respect to patients not presenting ex novo accompanying findings.
