[Rheumatoid arthritis flares]. / Poussées de la polyarthrite rhumatoïde.

Rheumatoid arthritis (RA) is a common chronic autoimmune inflammatory disease, primarily affecting the joints. Its activity is subject to exacerbations called flares. These RA flares are linked to cardiovascular, functional and radiological complications. The mechanisms behind these flares are still poorly understood. There is currently no reliable biomarker for the diagnosis of the flares. Diagnostic scores have been developed for research purposes but their application in clinical practice is not yet clear. The therapeutic approach includes acute treatment of the flare with corticosteroids and evaluation of the need for intensification of background therapy.

La polyarthrite rhumatoïde (PR) est une maladie inflammatoire chronique auto-immune fréquente, touchant principalement les articulations, dont l'activité peut être sujette à des exacerbations appelées « poussées ¼. Ces dernières sont liées à des complications cardiovasculaires, fonctionnelles et radiologiques. Les mécanismes à l'origine de ces poussées sont encore mal compris. Il n'existe pas à l'heure actuelle de biomarqueur fiable permettant de diagnostiquer les poussées. Des scores à but diagnostic ont été développés pour la recherche, mais leur application en clinique n'est pas encore claire. L'attitude thérapeutique comprend un traitement aigu de la poussée par une corticothérapie ainsi qu'une évaluation systématique de l'indication à une intensification du traitement de fond.

Reporting and Representativeness of Race, Ethnicity, and Socioeconomic Status in Systemic Sclerosis Randomized Trials: An Observational Study.

OBJECTIVE: To assess how and to what extent socioeconomic status and ethnicity/race of participants are reported in randomized controlled trials (RCTs) on systemic sclerosis (SSc), and to estimate the representativeness of different ethnic/racial groups in SSc RCTs. METHODS: We searched all published RCTs on SSc indexed in PubMed. We retrieved information on main features of RCTs published from 2000 onward and recorded for each study whether race/ethnicity was reported; how ethnicity/race was defined and assigned; and the number of patients included for each racial/ethnic group. Multivariable logistic regression was used to identify factors associated with race/ethnicity reporting. Proportion of races/ethnicities included in US-based RCTs on SSc was examined and compared with US demographic data. RESULTS: We included 106 studies, mostly conducted in Europe (42%) or North America (25%), published after 2010 (74%), and enrolling a total of 6,693 patients. About one-third of studies provided information about race/ethnicity, with no improved reporting over time. Only 2 papers reported patient's socioeconomic status. Study location (US or intercontinental) was the only significant factor associated with a better reporting of race/ethnicity in multivariable analysis. In studies where race/ethnicity was reported, White patients were mostly represented (79%), followed by Asian (7%), and African American (6%). In the sensitivity analysis limited to studies from the US, underrepresentation of African American patients was observed in the 2000-2010 time period, but not later. CONCLUSION: Documentation of race/ethnicity and socioeconomic status is poor in RCTs on SSc. More effort should be made to document race/ethnicity and socioeconomic status and to promote diversity in SSc RCTs.

Does the advertisement in Swiss pharmacy windows rest on evidence-based medicine? An observational study.

OBJECTIVES: The aim of the study was to analyse the proportion of evidence-based medication displayed in pharmacies and compare it between the different linguistic regions of the country, at different times of the year to determine the amount of proven effective medications indirectly recommended to the public in different parts of Switzerland. DESIGN: This is an observational study conducted by medical doctors in the department of internal medicine at the Spitalzentrum Biel, Switzerland. SETTING: The observation took place from July 2019 to May 2020. From a total of 1800 pharmacies in Switzerland, 68 different pharmacies were selected across the 3 main linguistic regions and the medication on display in their windows were examined 4 times a year regarding their efficacy. The displays of medication with or without evidence-based efficacy were described using absolute numbers and proportions and compared between the different linguistic regions at different seasons using χ2. PARTICIPANTS: There were no human or animal participants involved in this study. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome is the proportion of medication displayed in pharmacy windows with a proven effectiveness in medical literature. The secondary outcome was the variability of the primary outcome over time (seasonal changes), over the different linguistic regions of Switzerland and between chains and privately owned pharmacies. RESULTS: We examined 970 medications and found that over the whole year, there is a high proportion of non-evidence-based drugs (56,9%) displayed in pharmacies. Swiss German cantons display significantly more non-evidence-based medications in winter. We found no statistical difference for other seasons or between chains and privately owned pharmacies. CONCLUSION: Pharmacies in Switzerland tend to display significantly more non-evidence-based drugs, thus indirectly recommending them to the public. In a time of necessary expansion of self-medication by the population, this could incite consumers to buy drugs without proven effectiveness.

Early Switch From Intravenous to Oral Antibiotics in Skin and Soft Tissue Infections: An Algorithm-Based Prospective Multicenter Pilot Trial.

Background: In hospitalized patients with skin and soft tissue infections (SSTIs), intravenous (IV) empiric antibiotic treatment is initiated. The best time point for switching from IV to oral treatment is unknown. We used an algorithm-based decision tree for the switch from IV to oral antibiotics within 48 hours and aimed to investigate the treatment outcome of this concept. Methods: In a nonrandomized trial, we prospectively enrolled 128 patients hospitalized with SSTI from July 2019 to May 2021 at 3 institutions. Clinical and biochemical response data during the first week and at follow-up after 30 days were analyzed. Patients fulfilling criteria for the switch from IV to oral antibiotics were assigned to the intervention group. The primary outcome was a composite definition consisting of the proportion of patients with clinical failure or death of any cause. Results: Ninety-seven (75.8%) patients were assigned to the intervention group. All of them showed signs of clinical improvement (ie, absence of fever or reduction of pain) within 48 hours of IV treatment, irrespective of erythema finding or biochemical response. The median total antibiotic treatment duration was 11 (interquartile range [IQR], 9-13) days in the invention group and 15 (IQR, 11-24) days in the nonintervention group (P < .001). The median duration of hospitalization was 5 (IQR, 4-6) days in the intervention group and 8 (IQR, 6-12) days in the nonintervention group (P < .001). There were 5 (5.2%) failures in the intervention group and 1 (3.2%) in the nonintervention group after a median follow-up of 37 days. Conclusions: In this pilot trial, the proposed decision algorithm for early switch from IV to oral antibiotics for SSTI treatment was successful in 95% of cases. Clinical Trials Registration.
