RESUMO
BACKGROUND: Multiple sclerosis (MS) frequently affects women of childbearing age and pregnant women. OBJECTIVE: To assess the use of MS disease-modifying therapies (DMTs) during pregnancy in France over the last decade, marked by an increasing DMTs availability. METHODS: All pregnancies ended from April 2010 to December 2021 in women with MS were identified based on the nationwide Mother-Child Register EPI-MERES, built from the French National Health Data System (Système National des Données de Santé (SNDS)). RESULTS: Of a total of 20,567 pregnancies in women with MS, 7587 were exposed to DMT. The number of DMT-exposed pregnancies markedly increased from 1079 in 2010-2012 to 2413 in 2019-2021 (+124%), especially those exposed to glatiramer acetate, natalizumab, dimethyl fumarate, and anti-CD20. Among pregnancies of women on DMT 6 months before pregnancy, 78.0% underwent DMT discontinuation and 7.6% switched DMT, generally before (33.0% and 77.0%, respectively) or during the first trimester of pregnancy (58.3% and 17.8%, respectively). DMT discontinuation decreased from 84.0% in 2010-2012 to 72.4% in 2019-2021 and was less frequent among women aged ⩾35 years and those socioeconomically disadvantaged. CONCLUSION: Despite MS therapeutic management adaptations to pregnancy, exposure during pregnancy to treatments whose safety profile has not yet been clearly established has increased sharply over the last decade.

INTRODUCTION: France is a leading country for opioid agonist treatment providing, with a predominance of buprenorphine. General practitioners (GPs) are the main prescribers of buprenorphine, but they seem to be less involved over the last 10 years. This work is the second part of a larger study analysing buprenorphine prescribing among French GPs working in primary care, and aims to describe GPs' practices when prescribing buprenorphine. METHODS: This is a cross-sectional study conducted in France from March to July 2021 among a sample of GPs in the Sentinelles network, a national epidemiologic surveillance system. Data about the last situations of initiation and renewal of buprenorphine were collected. RESULTS: Among the 237 participants (34.3% response rate), 156 responded to the questionnaire about the last situation of renewal and 41 about the last situation of initiation. The last initiation occurred more than 12 months earlier for 46.3% of respondents, whereas the last renewal occurred less than 1 month ago for 68.6%. There was an over-representation of the male gender among the patients who were consulting (initiation 70.7%, renewal 68.6%). A majority of patients had an illicit opioid use disorder (initiation 78.0%, renewal 82.7%). Overall, GPs were involved in the general care of patients with opioids use disorder and in opioids harm reduction (initiation 87.8% and 82.9%, renewal 88.5% and 51.9%). CONCLUSION: Among buprenorphine prescribers, initiations were infrequent unlike renewals and involved mainly illicit opioid users.
RESUMO
INTRODUCTION: Although opioid substitution coverage in France is high and patient care with buprenorphine is mainly managed by general practitioners (GPs), buprenorphine sales have been decreasing since 2011, suggesting that French GPs are prescribing less buprenorphine. Yet this possible change in GP practices has not yet been investigated. This study aimed to examine primary care GPs' opinions about buprenorphine and habits related to prescribing buprenorphine. METHODS: The study team conducted a cross-sectional survey from March 2021 to July 2021 among a sample of GPs in the Sentinelles network, a French epidemiologic surveillance system based on primary care practitioners. The study collected information about substance use disorder (SUD) training, opinions on buprenorphine, and habits related to buprenorphine prescription were collected (initiation and renewal within the past two years). FINDINGS: Among the 237 participants (34 % response rate), 15.2 % reported having had specific training for SUD management. A majority reported a very positive (16 %) or positive (63.7 %) opinion of buprenorphine. Most participants agreed (61.2 %) or strongly agreed (31.2 %) that buprenorphine was efficacious in the treatment of illicit opioid use disorder. Of the 206 GPs who reported having treated patients with opioid use disorder in the past two years, 47 (22.8 %) had initiated a buprenorphine prescription, whereas 177 (85.9 %) had renewed a buprenorphine prescription. Previous SUD training was associated with initiating buprenorphine (OR 4.66; 95 % CI [2.15-10.08]), while female gender was associated with not initiating buprenorphine prescribing (OR 0.46; 95 % CI [0.22-0.98]). CONCLUSION: A sample of French GPs who work in primary care has a positive view of buprenorphine, but the absence of SUD training among this population may be a barrier to their prescribing buprenorphine.

During the COVID-19 pandemic, several generic variants emerged, including the Alpha variant, with increased transmissibility compared to historical strains. We aimed to compare the evolution of the viral load between patients infected with the Alpha variant and those infected with the historical SARS-CoV-2 strains, while taking into account the time interval between the onset of symptoms and samples. We used data collected from patients with an acute respiratory infection (mild to moderate symptoms) and seen in consultation in primary care, included in a prospective longitudinal study, COVID-A. Patients performed four salivary samples during the follow-up. All patients who had at least one of the saliva samples test positive for SARS-CoV-2 were included in the analysis. Overall, 118 patients were included: 89 infected by the historical strain and 29 infected by the Alpha variant. Even though we tended to observe a higher viral load in the Alpha variant group, we found no significant difference in the evolution of the viral load in saliva samples between patients infected with the Alpha variant of the SARS-CoV-2 and those infected by historical strains when controlling for the time interval between the onset of symptoms and sampling.
RESUMO
BACKGROUND: The present study was set up to evaluate the efficacy of virological surveillance using posterior oropharyngeal saliva samples to monitor the COVID-19 pandemic in general practice. METHODS: Posterior oropharyngeal saliva samples were collected without restriction on timing or alimentation by general practitioners from patients with acute respiratory infection (ARI) seen in consultation. Saliva samples were tested by real-time reverse transcription polymerase chain reaction for SARS-CoV-2 and 21 other respiratory pathogens. Results for SARS-CoV-2 in saliva samples were compared to results obtained using a nasopharyngeal swab (NPS) collected in a certified medical laboratory before or after the ARI consultation. RESULTS: Overall, 143 ARI patients were enrolled between 6 June 2020, and 19 January 2021. SARS-CoV-2 RNA was detected in 37.0% (n = 53) of saliva samples and in 39.0% (n = 56) of NPS. Both saliva and NPS were positive in 51 patients. Positive and negative results were concordant between saliva samples and NPS in 51 (96.2%) and in 85 (94.4%) patients, respectively, with a Cohen's Kappa coefficient of 0.89 (95% CI 0.82-0.97, p < 0.001). Other respiratory viruses were detected in 28.0% (n = 40) of the 143 saliva samples. CONCLUSIONS: Findings suggest that saliva samples could represent an attractive alternative to NPS for surveillance of SARS-CoV-2 in patients consulting for an ARI in primary care.
