OBJECTIVES: Assess the frequency of paradoxical reactions encountered in daily practice under tocilizumab, using the REGATE (Registry-RoActemra) registry. The secondary objectives were to determine the type of paradoxical reaction and the consequences of these reactions. METHODS: The REGATE registry is an independent prospective registry, promoted by the French Society of Rheumatology, consisting of patients treated with tocilizumab for rheumatoid arthritis. The paradoxical reaction was retained if it was a paradoxical precipitation of a condition for which tocilizumab was indicated, if tocilizumab was being used for an alternative indication, and if it appeared after at least one tocilizumab infusion. RESULTS: Among the 1491 patients included with at least one follow-up visit (3429 patient-years), a paradoxical reaction occurred in 9 patients (0.60% of patients; 2.62/1000 patient-years). These were 7 de novo pathologies (3 vasculitis, 3 uveitis, 1 lupus) and 2 exacerbations of pre-existing conditions (1 vasculitis, 1 lupus). Permanent discontinuation of tocilizumab was chosen for 5 patients. CONCLUSIONS: In the REGATE registry, the occurrence of paradoxical reactions in patients treated with tocilizumab was rare.

OBJECTIVES: The primary objective was to assess the diagnostic contribution of a second percutaneous needle biopsy in patients with spontaneous diskitis and negative findings from blood cultures and the first biopsy. We also assessed the sensitivity of the first biopsy and the diagnostic contribution of post-biopsy blood cultures. METHODS: Multicenter retrospective study of patients managed between 2004 and 2014. We excluded patients with postoperative diskitis. RESULTS: We identified 63 patients with spontaneous diskitis, negative blood cultures, and at least one percutaneous needle biopsy during the study period. The first biopsy established the diagnosis in 33 (52%) patients. Of the 30 remaining patients, 10 (33%) had a second biopsy, which was positive in 6 (60%), and 20 (67%) received probabilistic antibiotic therapy. There were 8 positive blood cultures after the first biopsy but, among them, 7 occurred in biopsy-positive patients. Biopsy yield varied with the guidance method (needle guidance software or imaging by computed tomography and/or fluoroscopy) and operators. Antibiotic therapy within the 6months preceding the first biopsy was significantly associated with having a negative first biopsy (15/30 versus 7/33; odds ratio, 3.13; 95% confidence interval, 1.07-9.13; P<0.05). CONCLUSION: In our study, a second needle biopsy was useful, providing the bacteriological diagnosis in 60% of cases of spontaneous diskitis with negative findings from blood cultures and the first biopsy.
