Sex/gender differences in spontaneous reports to a French Addictovigilance centre.

To specify psychoactive substances and related complications observed in spontaneous reports (SRs) in women versus men, we assessed SRs on substance-linked acute toxicity sent to a French Addictovigilance centre. Over the period 2021-2022, 880 SRs were analysed (33.4% concerned women). Severe complications concerned more men than women (70.3% versus 59.5%; p = 0.0014). In women, the main implicated substances were psychoactive medications (opioids, benzodiazepines). The most frequently reported complication was suicidal behaviour (14.6% versus 7.8%, p = 0.002). In men, SRs concerned mainly illicit substances (cocaine, amphetamines) or misuse of opioid maintenance therapy or nitrous oxide. The main complications in men were infections (12.97% versus 5.4%, p = 0.0006) and neurological troubles (37.6% versus 23.5%, p < 0.0001).Our data highlight sex/gender disparities in substance use and complications, in agreement with recent literature and French national Addictovigilance data.

Screening for hepatitis C virus at the time of mammography using rapid diagnostic tests in women aged between 50 and 74 years (Mamm'OC NCT05067374).

Chronic hepatitis C Virus (HCV) infection presents a global health challenge, with significant morbidity and mortality worldwide. Despite remarkable progress in treatment options, achieving elimination targets by 2030, as set by the World Health Organization, remains elusive. Our study aimed to address this gap by integrating HCV screening into a national breast cancer screening program. Between March 2022 and March 2023, a prospective cross-sectional multicenter study was conducted in four radiology centers in Montpellier, France. We proposed HCV screening to consecutive women undergoing mammography, targeting 1,500 participants aged 50-74 years. A rapid diagnostic test (RDT) for HCV antibodies (HCV Ab) was performed on capillary whole blood, with positive cases undergoing serological and RNA confirmation. Participants also completed a questionnaire on demographic data and risk factors. Acceptance rates, HCV prevalence, and linkage to care were assessed. The acceptance rate for this integrated screening approach was 82.4%. Notably, the seroprevalence of HCV was found to be 0.65%. Linkage to care was prompt, and the cascade of care demonstrated successful treatment outcomes. Importantly, the majority of detected infections were successfully resolved. These findings underscore the feasibility and acceptability of integrating HCV screening with breast cancer screening programs providing updated prevalence data and valuable insights for refining future screening strategies.

Community-based respondent-driven sampling as a strategy for drug use surveillance in a large French urban area.

BACKGROUND: Understanding drug use and behavior within the PWUD population is crucial to adapt harm reduction and prevention strategies, and provide improved addiction and medical treatment. However, in most countries such as France, the knowledge of drug use behaviors is likely biased as it originates from addiction centers which are attended by only an unknown proportion of PWUD. The objectives of this study were to describe drug use behavior in a population of active PWUD in the urban area of Montpellier, South of France. METHODS: We implemented a community-based respondent-driven sampling survey (RDSS), a validated strategy to obtain a representative sample of a population, to recruit PWUD in the city. Adult individuals reporting frequent psychoactive drug use other than cannabis, with confirmation by urine test, were eligible. Beside HCV and HIV testing, trained peers interviewed participants on their drug consumption and behavior using standardized questionnaires. Fifteen seeds launched the RDSS. RESULTS: During the 11 weeks of the RDSS, 554 actives PWUD were consecutively included. They were mostly men (78.8%), had a median age of 39 years, and only 25.6% had a stable living place. On average, participants consumed 4.7 (± 3.1) different drugs, and 42.6% smoked free-base cocaine. Unexpectedly, heroin and methamphetamine were consumed by 46.8% and 21.5% of participants, respectively. Among the 194 participants injecting drugs, 33% declared sharing their equipment. CONCLUSION: This RDSS highlighted a high consumption of heroin, crack and methamphetamine in this PWUD population. These unexpected results can be explained by low attendance to addiction centers, the source of drug use reports. Despite free care and risk reduction equipment in the city, sharing was very frequent among injectors, challenging the current program of harm reduction.

Recurrent alcoholic cirrhosis in severe alcoholic relapse after liver transplantation: a frequent and serious complication.

OBJECTIVES: Alcoholic liver disease (ALD) is a major indication for liver transplantation (LT). Recurrent alcoholic cirrhosis (RAC) after LT can occur but has not been studied. The aims of this study were to estimate the prevalence, predictive factors, and natural history of RAC after LT. METHODS: All patients transplanted for ALD between 1990 and 2007 in three French centers were included. The diagnosis of RAC was based on histological evidence or a series of features combined with severe alcoholic relapse. RESULTS: Among 1,894 adult LT patients, 712 were transplanted for alcoholic cirrhosis and survived >6 months. After a mean follow-up of 9 years, 128 patients (mean age at LT 47.2±7.1 years old, 78.9% men) experienced severe alcoholic relapse (18.0% of cases). Severe alcoholic relapse occurred after a median delay of 25 months (range 4-157) after LT. RAC was diagnosed in 41 patients with severe relapse (32%). The diagnosis of RAC was made after a median delay of 5.1 years (range 1.8-13.9) after LT and of 4.0 years (range 1.2-11.5) after relapse. RAC was significantly associated with younger age and a shorter period of pre-LT abstinence. One-, 5-, 10-, and 15-year survival was 100, 87.6, 49.7, and 21.0%, respectively, for RAC patients vs. 100, 89.4, 69.9, and 41.1%, respectively, for the patients without RAC (P<0.001). CONCLUSIONS: RAC occurs in <6% of ALD transplant patients. One-third of severe alcoholic relapse patients develop RAC <5 years after transplantation with a very poor prognosis.
