- Abstract
Background: Azithromycin has been shown to be beneficial in preventing infectious diseases, including malaria, infectious diarrhoea and pneumonia. A cluster randomised control trial on azithromycin MDA in children in Niger, Malawi and Tanzania found a reduction in all-cause under-five (U5) mortality in communities who received azithromycin compared to placebo. However, the reduction was largest and statistically significant only in Niger. The purpose of this trial is to evaluate the impact of azithromycin plus intermittent preventive treatment in infants (IPTi), recently renamed by the World Health Organisation as perennial malaria chemoprevention (PMC), with sulfadoxine-pyrimethamine (SP) on all-cause mortality up to 18 months of age in children living in areas of high mortality burden through the Expanded Program on Immunisation (EPI) in Sierra Leone., Methods: The Improving Care through Azithromycin Research for Infants in Africa (ICARIA) trial is a phase III two-arm, individually randomised, double-blinded, placebo-controlled trial administering oral AZI (20 mg/kg bodyweight) at three time points to children attending EPI visits in Sierra Leone. A total of 20,560 infants attending the first EPI contact at around 6 weeks of age are recruited and randomised to AZI or placebo in a 1:1 ratio. The second and third AZI/placebo doses are given at 9 and 15 months of age. The primary outcome of the trial is all-cause mortality rate at 18 months of age assessed through mortality surveillance. Other trial outcomes include the impact on antimicrobial resistance, and on the immune response to certain key routine EPI immunisations, the safety of the intervention, the prevalence of SP resistance markers and the feasibility, and acceptability of adding AZI to the EPI programme., Discussion: The trial will provide the evidence needed to inform policy regarding the adoption and large-scale implementation of AZI in areas of high-mortality burden in sub-Saharan Africa., Trial Registration: ClinicalTrials.gov NCT04235816.

- Abstract
Background: Despite the potential foetal and maternal risks of self-medication, studies on self-medication practice and the safety profile of medicines used during pregnancy are scarce in our setting. This study determined the self-medication practice and safety profile of medicines used among pregnant women., Methods: This cross-sectional study was conducted in face-to-face interviews among 345 pregnant women at three hospitals in Sierra Leone. Data were analysed using descriptive statistics and binary logistic regression to determine the prevalence and associated factors of self-medication., Results: A total of 345 pregnant women participated in the study. The prevalence of self-medication prevalence among pregnant women with conventional and/or herbal medicine was 132 (38.3%). Also, 93 (75%) of the conventional medicines (CMs) were categorised as probably safe, of which paracetamol 36 (29.0%) was commonly used, followed by amoxicillin 23 (18.5%) and antimalarials 22 (17.7%) for common illnesses such as headache 30 (25.4%), urinary tract infection 23 (19.4%) and malaria 22 (18.6%). The most common reason for self-medication was previous experience with the disease 24 (27.3%). Luffa acutangula 19 (30.2%) was the most used herbal medicine (HM), and Oedema 30 (47.6%) was the most reported ailment. Among the HM users, 34 (54.0%) believe they are more effective than CMs. Secondary school education (AOR = 2.128, 95%CI = 1.191-3.804, p = 0.011), tertiary education (AOR = 2.915, 95%CI = 1.104-7.693, p = 0.031), monthly income of greater than NLe 1,000 (AOR = 4.084, 95% CI = 1.269-13.144, p = 0.018), and perceived maternal illness (AOR = 0.367, CI = 0.213-0.632, p = <0.001) were predictors of self-medication., Conclusion: Self-medication practice was highly prevalent and was associated with educational status, monthly income, and perceived maternal illness during pregnancy. Therefore, intervention programmes should be designed and implemented to minimise the practice and risk associated with self-medication among pregnant women., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2024 The Author(s).

- Abstract
Background: The rVSVΔG-ZEBOV-GP vaccine (ERVEBO®) is a single-dose, live-attenuated, recombinant vesicular stomatitis virus vaccine indicated for the prevention of Ebola virus disease (EVD) caused by Zaire ebolavirus in individuals 12 months of age and older., Methods: The Partnership for Research on Ebola VACcination (PREVAC) is a multicenter, phase 2, randomized, double-blind, placebo-controlled trial of 3 vaccine strategies in healthy children (ages 1-17) and adults, with projected 5 years of follow-up (NCT02876328). Using validated assays (GP-ELISA and PRNT), we measured antibody responses after 1-dose rVSVΔG-ZEBOV-GP, 2-dose rVSVΔG-ZEBOV-GP (given on Day 0 and Day 56), or placebo. Furthermore, we quantified vaccine virus shedding in a subset of children's saliva using RT-PCR., Results: In total, 819 children and 783 adults were randomized to receive rVSVΔG-ZEBOV-GP (1 or 2 doses) or placebo. A single dose of rVSVΔG-ZEBOV-GP increased antibody responses by Day 28 that were sustained through Month 12. A second dose of rVSVΔG-ZEBOV-GP given on Day 56 transiently boosted antibody concentrations. In vaccinated children, GP-ELISA titers were superior to placebo and non-inferior to vaccinated adults. Vaccine virus shedding was observed in 31.7% of children, peaking by Day 7, with no shedding observed after Day 28 post-dose 1 or any time post-dose 2., Conclusions: A single dose of rVSVΔG-ZEBOV-GP induced robust antibody responses in children that was non-inferior to the responses induced in vaccinated adults. Vaccine virus shedding in children was time-limited and only observed after the first dose. Overall, these data support the use of rVSVΔG-ZEBOV-GP for the prevention of EVD in at-risk children.
