Survey of adolescents' needs and parents' views on sexual health in juvenile idiopathic arthritis.

BACKGROUND: Although the advent of new therapeutics for juvenile idiopathic arthritis (JIA) patients has considerably lessened the impact of the disease and reduced its sequelae, the outcomes of JIA remain important in their lives. Disease repercussions and side effects of treatments may affect sexual health and cause psychological distress. This aim of the study was to determine the expectations of adolescent JIA patients and the perceptions of their parents regarding knowledge and communication with healthcare providers (HCPs) in the field of sexual health (SH). METHODS: In France, from September 2021 to April 2022, a survey was conducted, using anonymous self-administered questionnaires, among JIA patients (adults (aged 18-45 years) to provide insights from their recollection of their adolescence) and their parents in nine rheumatology centers and three patient associations. RESULTS: The responses to the 76 patient questionnaires and 43 parent questionnaires that were collected were analyzed. Half of the patients thought JIA impacted their romantic relationships, but the results were less clear-cut for their sexual activity; and 58.7% of the patients said they would be comfortable discussing the subject with HCPs, but only 26.3% had done so, mainly regarding biomedical issues. The patients and their parents thought that ideally, the topic should be addressed in an individual patient education session at the hospital (51.3% and 34.9%, respectively), in a regular consultation (47.4% and 53.5%), or in a dedicated consultation requested by the adolescent without the adolescent's parents being informed (38.2% and 20.9%). Most of the respondents thought HCPs should be proactive in SH (77.6% of the patients and 69.8% of their parents). More patients than parents said the following digital information tools must be used: videos (29.0% vs. 9.3%, p = 0.0127) and smartphone applications (25.0% vs. 9.3%, p = 0.0372). CONCLUSION: HCPs should consider addressing the unmet need for SH discussions during their patient encounters. To meet this need, we propose concrete actions in line with the wishes of patients and parents. CLINICAL TRIAL REGISTRATION NUMBER: NCT04791189.

A Population Pharmacokinetic Analysis of Continuous Infusion of Cloxacillin during Staphylococcus aureus Bone and Joint Infections.

Intravenous administration of antibiotics is recommended during the early phase of methicillin-susceptible S. aureus (MSSA) bone and joint infection (BJI). We sought to compare the plasma concentrations of cloxacillin administered alternately by continuous and intermittent infusion (CI and ItI) in patients with MSSA BJI. In this prospective crossover trial, patients were randomly assigned to receive either 3 days of CI (two 75-mg/kg 12-h cloxacillin infusions per day) and then 3 days of ItI (four 37.5-mg/kg 1-h cloxacillin infusions per day) or vice versa. The drug concentration measurement was performed on day 3 of each type of administration at 1, 6, and 11 h and at 1, 2, 3, 4, and 6 h after the beginning of CI and ItI, respectively. We used the nonparametric algorithm NPAG to estimate population pharmacokinetic (PK) parameters. The final model was used to perform pharmacokinetic/pharmacodynamic (PK/PD) simulations and calculate the probabilities of target attainment (PTA) for several ItI and CI dosing regimens. We considered two PK/PD targets of time spent above the MIC for free cloxacillin concentrations (fT>MIC): 50 and 100%. Eighty-four concentrations from 11 patients were analyzed. A two-compartment model adequately described the data. ItI with q6h regimens and short 1-h infusions of 2,000 or 3,000 mg were associated with low PTA, even for the low target (50% fT>MIC) while 3-h infusions and continuous infusions (6 to 12 g/day) were associated with a PTA of >90% for an MIC up to 0.5 mg/liter. These results support the use of prolonged or continuous infusion of cloxacillin in patients with BJI.
