Clinical and ultrasonographic evaluation of the window of opportunity for retreatment with rituximab in rheumatoid arthritis patients from a multicentre real-life study.

OBJECTIVES: To determine a potential window of opportunity for retreatment with rituximab in patients with rheumatoid arthritis (RA) from a multicentre longitudinal real-life study based on tight monitoring with ultrasonography (US). METHODS: Thirty RA patients treated with rituximab were included. US parameters were collected at each time (8 visits) of the 18-month follow-up, notably the global score of power Doppler (PD) activity. Clinical relapse was defined as a DAS28 ESR of >3.2 after 6 months in responders while US relapse was defined as an increase of ≥20% of the global score of PD activity. The decision of retreatment was based exclusively on clinical findings. RESULTS: A total of 29 patients were analysed (mean (SD) age: 57.2 (12.2) years; female gender: 66%). The mean (SD) PD score decreased from 8.8 (5.2) at baseline to 4.9 (4.3) at 6 months (p <0.0001). A clinical response was observed at Month 4 or Month 6 for 93% of patients. A total of 19 patients had a first clinical relapse (with or without US relapse) after Month 6 (18 of them were retreated with rituximab). Among 10 patients without clinical relapse, 3 had US relapse (only one was retreated) and 7 had no US relapse (but 4 were retreated). CONCLUSIONS: This study highlights a great heterogeneity in terms of sequence of clinical relapse, US relapse and retreatment in RA patients receiving rituximab. Therefore, US monitoring does not seem to be relevant to determine the best time for retreatment with rituximab.

Microbiological diagnosis of suspected vertebral osteomyelitis with a focus on the yield of percutaneous needle biopsy: a 10-year cohort study.

This study aims to evaluate in patients hospitalized for vertebral osteomyelitis (VO) the effectiveness of bacteriological diagnosis and the yield of percutaneous needle biopsy (PNB) and to identify factors associated with the result of PNB. This retrospective, two-centre study was conducted between 2000 and 2009. Data on patients with VO were retrieved from the diagnosis database and confirmed by checking medical records. A total of 300 patients with VO were identified; 31 received antibiotics without bacteriological diagnosis, and 269 patients with spondylodiscitis imaging were included. Eighty-three (30.9%) and 18 (6.7%) infections were documented by blood cultures and by bacteriological samples other than PNB, respectively; 168 patients with no bacteriological diagnosis had PNB. Of these, 92 (54.8%) were positive and identified the pathogen and 76 (45.2%) were negative. The most common bacteria were Staphylococcus aureus (34.3%), Streptococcus spp. (20.6%) and coagulase-negative staphylococcus (14.8%). After multivariate analysis, the only factor associated with negative PNB was previous antibiotic intake (OR: 2.31 [1.07-5.00]). When VO was suspected on imaging, bacteriological investigation identified the microorganism in 209/300 (70%) of the cases. The yield of PNB was 54.8%. The only predictor of PNB negativity was previous antibiotic intake. Therefore, we believe that a second PNB should be done after a sufficient delay withdrawal of antibiotics if the first sample was negative. The study was retrospectively registered by the local ethics committee (N°E2019-61).

Clinical impact of a personalized pharmaceutical plan on opioid management in non-cancer pain: a pilot study.

Non-cancer pain of the locomotor apparatus is the main symptom justifying referral to a rheumatologist with potential introduction of opioids, leading to addiction if misused. The objective was to evaluate the impact of a personalized pharmaceutical plan on patients' knowledge of their opioid treatment and its duration. This prospective non-randomized pilot study was conducted during 7 months with standardized data collected in a French rheumatology department. Patients with rheumatic diseases and non-cancer pain requiring opioid treatment were included. The intervention group had a 30-min opioid-targeted pharmaceutical interview and received a full medication plan and the control group received usual care. A total of 17 patients were included in the intervention group and 18 in the control group. Among patients in the intervention group, only 6 (35%) knew that immediate-release opioids have a rapid and short action, 9 (53%) were worried about taking opioids, and 13 (76%) reported that they would refer to the information document provided if side effects occurred. A trend toward a shorter duration of treatment was observed in the study group (HR = 1.87, 95% CI 0.93 to 3.76, p = 0.08), but this trend was attenuated when adjusting on hospital duration (HR = 1.53, 95% CI 0.74 to 3.15, p = 0.25). This pilot study provides preliminary evidence on the role of the clinical pharmacist in the management of non-cancer pain with strong opioids. Clinical benefits will be assessed in a randomized study. Key Points • Knowledge of opioids is insufficient in rheumatology patients with non-cancer pain. • Pharmaceutical interviews may improve patients' knowledge of opioids.

No impact of tumor necrosis-factor antagonists on the joint manifestations of sarcoidosis.

OBJECTIVE: The use of anti-tumor necrosis factor (TNF) agents to treat joint manifestations of sarcoidosis has not been described. We evaluated the efficacy and safety of three such biologics in patients with these symptoms refractory to conventional therapy (nonsteroidal anti-inflammatory drugs, corticosteroids, and/or disease-modifying antirheumatic drugs). METHODS: This retrospective study, covering January 2001 to September 2011, examined clinical-biological parameters collected before anti-TNF treatment (age, sex, duration of disease evolution, drugs taken), and at introduction and under anti-TNF therapy (number of painful and swollen joints, visual analog scale score of global disease activity, disease-activity score of 28 joints with erythrocyte sedimentation rate or C-reactive protein, TNF-antagonist duration). At 3, 6, and 12 months, anti-TNF impact on joints and the therapeutic response according to European League Against Rheumatism criteria used for rheumatoid arthritis were assessed. RESULTS: Ten patients' data were evaluated; some of them had received several anti-TNF agents (median [range] duration on each biotherapy was 10 [4-30] months), which enabled analysis of 19 prescriptions. The total duration of anti-TNF exposure was 17.6 patient-years, which was started a median of 3 (0.33-17) years after sarcoidosis diagnosis. The median numbers of painful and swollen joints were 1 (0-28) and 0 (0-9), respectively. Despite rapid efficacy, after 1 year of treatment, clinical (especially joint) and biological parameters were comparable to pretreatment, and only the corticosteroid dose was significantly lower (P=0.03). One case of mild skin toxicity was noted. CONCLUSION: TNF antagonists allowed significant steroid sparing and were well tolerated, but do not seem to be effective against sarcoidosis joint involvement.
