Diagnosis and treatment of Tropheryma whipplei infection in patients with inflammatory rheumatic disease: Data from the French Tw-IRD registry.

OBJECTIVES: Tropheryma whipplei infection can manifest as inflammatory joint symptoms, which can lead to misdiagnosis of inflammatory rheumatic disease and the use of disease-modifying antirheumatic drugs. We investigated the impact of diagnosis and treatment of Tropheryma whipplei infection in patients with inflammatory rheumatic disease. METHODS: We initiated a registry including patients with disease-modifying antirheumatic drugs-treated inflammatory rheumatic disease who were subsequently diagnosed with Tropheryma whipplei infection. We collected clinical, biological, treatment data of the inflammatory rheumatic disease, of Tropheryma whipplei infection, and impact of antibiotics on the evolution of inflammatory rheumatic disease. RESULTS: Among 73 inflammatory rheumatic disease patients, disease-modifying antirheumatic drugs initiation triggered extra-articular manifestations in 27% and resulted in stabilisation (51%), worsening (34%), or improvement (15%) of inflammatory rheumatic disease. At the diagnosis of Tropheryma whipplei infection, all patients had rheumatological symptoms (mean age 58 years, median inflammatory rheumatic disease duration 79 months), 84% had extra-rheumatological manifestations, 93% had elevated C-reactive protein, and 86% had hypoalbuminemia. Treatment of Tropheryma whipplei infection consisted mainly of doxycycline plus hydroxychloroquine, leading to remission of Tropheryma whipplei infection in 79% of cases. Antibiotic treatment of Tropheryma whipplei infection was associated with remission of inflammatory rheumatic disease in 93% of cases and enabled disease-modifying antirheumatic drugs and glucocorticoid discontinuation in most cases. CONCLUSIONS: Tropheryma whipplei infection should be considered in inflammatory rheumatic disease patients with extra-articular manifestations, elevated C-reactive protein, and/or hypoalbuminemia before disease-modifying antirheumatic drugs initiation or in inflammatory rheumatic disease patients with an inadequate response to one or more disease-modifying antirheumatic drugs. Positive results of screening and diagnostic tests for Tropheryma whipplei infection involve antibiotic treatment, which is associated with complete recovery of Tropheryma whipplei infection and rapid remission of inflammatory rheumatic disease, allowing disease-modifying antirheumatic drugs and glucocorticoid discontinuation.

Management and outcome of native joint septic arthritis: a nationwide survey in French rheumatology departments, 2016-2017.

OBJECTIVES: To describe current management and outcome of native joint septic arthritis (NJSA) in French rheumatology departments. METHODS: For this retrospective, nationwide multicentric study, 127 French rheumatology departments were contacted to report up to 12 cases of NJSA that occurred between 1 January 2016 and 31 December 2017. Characteristics, diagnosis procedures, therapeutic management and outcome were recorded. RESULTS: Overall, 362 patients were included (mean age 64.0±18.6 years, median Charlson comorbidity index 3.5 (0-14)). Knee was the most frequent site (n=160 (38.9%)), and Staphylococcus sp (n=185 (51.4%)), the most frequent pathogen. All patients received antibiotics for a mean duration of 46.8 (±22.0) days, including intravenous route for a mean of 17.2 (±15.4) days. Management was heterogeneous. Surgical procedure was performed in 171 (48.3%), joint immobilisation in 128 (43.8%). During follow-up, 91 (28.3%) patients have had serious complications and 28 (9.2%) of them died. Factors associated with 1-year mortality were age (OR 1.08, 95% CI 1.04 to 1.13; p<0.001), Charlson's index (OR 1.30, 95% CI 1.06 to 1.58; p=0.012), presence of bacteraemia (OR 4.02, 95% CI 1.35 to 11.99; p=0.008), antibiotic use in the previous 3 months (OR 3.32, 95% CI 1.11 to 9.87; p=0.029) and Staphylococcus aureus NJSA compared with Streptococcus sp. NJSA (OR 7.24, 95% CI 1.26 to 41.68, p=0.027). The complete recovery with no adverse joint outcome at 1 year was observed in n=125/278 patients (55.0%). CONCLUSION: Prognosis of NJSA remained severe with a high rate of morbimortality. Its management was very heterogeneous. This study highlights the importance of the new French recommendations, published after the completion of the study, in order to facilitate NJSA management.

Management of acromioclavicular joint disease by manual therapy versus corticosteroid injections: the protocol of a non-inferiority study.

INTRODUCTION: Degenerative acromioclavicular joint pain accounts for about 4% of shoulder pain. Various medical and non-medical treatment strategies are available for acromioclavicular joint disease but it is difficult to conduct a comparative evaluation of these treatments. The few studies dealing with the medical management of the disease have conducted no comparative assessment of drug therapies, physiotherapy, joint manipulation and corticosteroid injections. The primary goal of this study is to determine whether manual therapy is not inferior to ultrasound-guided injection of a corticosteroid preparation to decrease acromiocalvicular joint pain at 3 months. METHODS AND ANALYSIS: The acromioclavicular arthropathy managed by manual therapy is a monocentric, comparative, randomised, controlled, non-inferiority study conducted in the Rheumatology Department of Vendée Departmental Hospital, involving two parallel groups receiving either corticosteroid injections or manual therapy. The inclusion criteria are patients who suffer from pain in the shoulder or the proximal part of the arm, with pain located on palpation of the acromioclavicular joint associated with a positive cross-arm test and a positive O'Brien test. Randomisation will be at a 1:1 ratio. The injection group will receive a single ultrasound-guided injection of 1 mL of Diprostène and the manual therapy group will receive between one and three sessions at intervals of one per week. The primary outcome will be to compare the Visual Analogue Scale for pain-activity-related score at 3 months for both groups. ETHICS AND DISSEMINATION: The study project has been approved by the appropriate ethics committee (Committee for the Protection of Patients Ouest II in Angers, 30 April 2019, with the registration number of 2019/22). In agreement with current French regulations, signed informed written consent will be obtained from each patient. Results of the main trial and of the secondary endpoints will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT03951480.
