Intravenous versus subcutaneous tocilizumab in Takayasu arteritis: multicentre retrospective study.

OBJECTIVES: In this large multicentre study, we compared the effectiveness and safety of tocilizumab intravenous versus subcutaneous (SC) in 109 Takayasu arteritis (TAK) patients. METHODS: We conducted a retrospective multicentre study in referral centres from France, Italy, Spain, Armenia, Israel, Japan, Tunisia and Russia regarding biological-targeted therapies in TAK, since January 2017 to September 2019. RESULTS: A total of 109 TAK patients received at least 3 months tocilizumab therapy and were included in this study. Among them, 91 and 18 patients received intravenous and SC tocilizumab, respectively. A complete response (NIH <2 with less than 7.5 mg/day of prednisone) at 6 months was evidenced in 69% of TAK patients, of whom 57 (70%) and 11 (69%) patients were on intravenous and SC tocilizumab, respectively (p=0.95). The factors associated with complete response to tocilizumab at 6 months in multivariate analysis, only age <30 years (OR 2.85, 95% CI 1.14 to 7.12; p=0.027) and time between TAK diagnosis and tocilizumab initiation (OR 1.18, 95% CI 1.02 to 1.36; p=0.034). During the median follow-up of 30.1 months (0.4; 105.8) and 10.8 (0.1; 46.4) (p<0.0001) in patients who received tocilizumab in intravenous and SC forms, respectively, the risk of relapse was significantly higher in TAK patients on SC tocilizumab (HR=2.55, 95% CI 1.08 to 6.02; p=0.033). The overall cumulative incidence of relapse at 12 months in TAK patients was at 13.7% (95% CI 7.6% to 21.5%), with 10.3% (95% CI 4.8% to 18.4%) for those on intravenous tocilizumab vs 30.9% (95% CI 10.5% to 54.2%) for patients receiving SC tocilizumab. Adverse events occurred in 14 (15%) patients on intravenous route and in 2 (11%) on SC tocilizumab. CONCLUSION: In this study, we confirm that tocilizumab is effective in TAK, with complete remission being achieving by 70% of disease-modifying antirheumatic drugs-refractory TAK patients at 6 months.

Common diagnoses in internal medicine in Europe 2009: a pan-European, multi-centre survey.

OBJECTIVE: Information on the medical problems and diseases encountered by practicing Internists in the hospital environment is lacking. The aim of this study is to assess the prevalence of various diagnostic categories that present to internists in the hospital setting in Europe. DESIGN: A pan-European study used the Young Internists Research Network of the European Federation of Internal Medicine. RESULTS: Data on 1501 patients from 31 physicians in 18 European countries were included in the study. The patients carried an average of 2.75 (+/-2.22) chronic medical diagnoses, ranging from 0 to 18. The most common presenting complaint was shortness of breath, followed by chest pain and abdominal pain. A cardiac condition was most common, followed by infectious disease. The complexity of patients averaged 2.5 (+/-1.14). CONCLUSIONS: The results of this study will be useful for the development of a modern internal medicine curriculum, both at the graduate and postgraduate level, which reflects the competencies required for the delivery of comprehensive patient care in internal medicine wards.
