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.

Lung sarcoidosis induced by TNF antagonists in rheumatoid arthritis: a case presentation and a literature review.

Abstract We report the case of a 72 year-old woman with established rheumatoid arthritis diagnosed with pulmonary granulomatosis compatible with sarcoidosis after 49 months of treatment with etanercept. The symptoms and radiology remitted after the suspension of treatment against tumor necrosis factor (TNF) and with a course of steroids. To date, 27 cases of histologically-proven pulmonary sarcoidosis have been reported in relation to anti-TNF therapy, with etanercept being more frequent in comparison with the anti-TNF monoclonal antibodies infliximab and adalimumab. Probable pathogenic mechanisms of the paradoxical effect of anti-TNF treatment are discussed. It is important for clinicians to be aware of this potential and uncommon complication of biological therapy with TNF antagonists.

Sarcoidosis pulmonar inducida por antagonistas del factor de necrosis tumoral en la artritis reumatoide: presentación de un caso y revisión de la literatura médica

We report on a 72 year-old woman with long-standing rheumatoid arthritis diagnosed as granulomatosis due to pulmonary sarcoidosis after 49 months of treatment with etanercept. A clinical and radiological improvement was seen after tumor necrosis factor (TNF) antagonist withdrawal plus a course of steroids. Currently, 27 cases of histological proven sarcoidosis with pulmonary involvement have been reported in relation to anti-TNF therapy, with etanercept being more frequent in comparison with the anti-TNF monoclonal antibodies infliximab and adalimumab. Potential pathogenic mechanisms of the paradoxical effect of anti-TNF treatment is discussed. It is important for clinicians to be aware of this potential and uncommon complication of biological therapy with TNF antagonists.

Reducción de dosis de terapias biológicas en enfermedades reumáticas: análisis descriptivo de 153 pacientes en condiciones de práctica clínica

OBJECTIVE To analyze the frequency and characteristics of dose reduction of biological agents in a cohort of patients with chronic arthritis, in clinical practice conditions in a tertiary level hospital. MATERIAL AND METHODS Descriptive, cross-sectional study, which included all patients, followed consecutively during 6 months (June 2011-November 2011), by one investigator, with patients who at least have received one dose of biological agents in 2011. RESULTS We included 153 patients: Rheumatoid arthritis (RA) (n=82), ankylosing spondylitis (n=29), psoriatic arthritis (n=20), and miscellaneous group (n=22). Mean disease duration was 14.9±7.7 years. At the time of analysis, 70 patients (45.7%) were receiving low doses of biological therapy (50% in miscellaneous group group, 50% in psoriatic arthritis, 48.2% in ankylosing spondylitis, and 42.6% in RA). Mean time of dosage reduction was 17.4±17.5 months. The most common biological agents used in low dose were: etanercept, adalimumab and tocilizumab; 57.6%, 54.9% and 40% respectively, in patients with a reduced dose of biological therapy. The patients at low dose of biological therapy compared with standard dose, had similar mean disease duration, but received significantly less DMARDs, glucocorticoids and NSAIDs, and similar biological agent duration. RA patients with reduced biological treatment, at the time of analysis, had higher remission rates versus patients receiving a standard dose (82.9% vs 34%, p<0.0001). The medical decision at the time of analysis was to maintain low-dosage biological treatment in almost all patients. CONCLUSION In our clinical practice, 45.7% of our chronic arthritis patients receive low dose of biological therapy, after achieving remission or low activity at standard doses, maintaining a good control of the disease.

Is There Subclinical Synovitis in Patients with Palindromic Rheumatism in the Intercritical Period? A Clinical and Ultrasonographic Study According to Anticitrullinated Protein Antibody Status

Objective. To investigate the presence of subclinical synovitis by ultrasound (US) and the clinical phenotype in patients with palindromic rheumatism (PR) according to anticitrullinated protein antibody (ACPA) status. Methods. Fifty-four patients with PR were studied. Clinical, demographic, serological, and therapeutic characteristics were compared in ACPA-positive and ACPA-negative patients. US searching for synovial hypertrophy (SH) and power Doppler signal (PDUS) in 22 joints of the hands was performed in the intercritical period. The results were compared according to ACPA status and with a healthy control group (n = 30). In 10 patients, US was performed during the joint attack. Results. Most patients were female (63%) with a mean disease duration of 11.6 ± 10.7 years. Thirty-six patients (66.7%) were ACPA-positive. ACPA-positive patients had a shorter duration of attacks, a younger age, and less knee involvement at disease onset. US examination showed SH grade ≥ 1 in 79.6% of patients with PR and 50% of controls. Significant US results (SH ≥ 2 or PDUS) were observed in 2.7% and 1.4% of joints assessed and in 33% and 25.9% of patients with PR, respectively. Only 4 patients (7.4%) had US active synovitis (SH ≥ 2 plus PDUS) in at least 1 joint. US assessment showed no significant differences between ACPA-positive and ACPA-negative patients. PDUS was observed in 7 out of 10 patients during attacks. Conclusion. Some differences emerged in the clinical phenotype of PR according to ACPA status. Most patients with PR do not have US subclinical synovitis in the intercritical period, even those who are ACPA-positive.

Valoración laríngea mediante videolaringoestroboscopia en pacientes con artritis reumatoide

AIM To evaluate the larynx involvement in patients with rheumatoid arthritis (RA) in a clinical setting and correlate with the different clinical features related to more aggressive disease. METHODS Cross-sectional study including 36 consecutive patients with RA. Reflux symptoms were evaluated by the Reflux Symptom Index (RSI) and vocal cord impairment by the Voice Handicap Index-10 (VHI-10). Laryngeal involvement was done by videolaryngostroboscopy (VLS). RESULTS The mean age was 56,3 ± 14 years with a mean disease duration of 2,6 ± 3,1 years (range 0-16 years). Voice use was considered as professional users in 33%. Twenty-four (67%) out of 36 patients had abnormal findings of VLS. One patient had larynx nodules (bamboo nodules). Eleven patients (31%) were diagnosed with muscle tension dysphonia, and there were symptoms and signs of pharyngeal-laryngeal reflux in 23 (64%) patients. No signs of cricoarytenoid joint impairment was found. CONCLUSIONS Organic larynx involvement was uncommon in patients with RA. However symptoms and signs of pharyngeal-laryngeal reflux were seen in around 60% of patients. There was no correlation between the clinical phenotype, severity of disease, immunological profile or treatment with VLS findings.

Recomendaciones para el manejo de la comorbilidad en la práctica clínica en pacientes con espondiloartritis axial

OBJECTIVES To identify priorities among comorbidities in axial spondyloarthritis (AxSpA) and recommend how to follow them from an eminently practical perspective. METHODS A multidisciplinary group was selected (10 rheumatologists-six of them experts in AxSpA-, 2 general practitioners, an internist, a cardiologist, a gastroenterologist and a psychologist). In a first discussion meeting, the scope and users were established and a list of comorbidities was voted based on frequency and impact. The panelists had to defend the inclusion of each comorbidity/item in the document with consistent arguments. Four panelists and two methodologists developed systematic reviews on controversial topics. In a second meeting, the results of the reviews and the arguments concerning the items to be included were presented. After the meeting, the final document was drafted. RESULTS The final document includes two checklists, one for health professionals and another for patients; they incorporate cardiovascular risk, renal comorbidities, gastrointestinal risk, lifestyle, risk of infections and vaccinations, pulmonary involvement, concomitant medication, psycho-affective disorders, osteoporosis, and risk of fracture. In addition, the document reflects the arguments favoring the inclusion of each item and how to record the items for subsequent collection. The panel considered it also appropriate to likewise establish «practices to avoid» applicable to comorbidity in AxSpA. CONCLUSIONS Two checklists and a list of situations to avoid were generated to facilitate the management of comorbidities in AxSpA. In a future step, their utility and acceptance will be tested by a broad group of users that includes doctors, patients and nurses.
