Cohort Study: Lower Risk of Cardiovascular Complications in Post–COVID-19 Vaccine Myocarditis Compared to Conventional Etiologies
7 Sep, 2024 | 20:36h | UTCStudy Design and Population: This French nationwide cohort study included 4,635 individuals aged 12-49 hospitalized for myocarditis between December 2020 and June 2022. The cohort was divided into three groups: 558 patients with post–COVID-19 mRNA vaccine myocarditis, 298 with post–COVID-19 infection myocarditis, and 3,779 with conventional myocarditis.
Main Findings: At 18 months of follow-up, the frequency of cardiovascular events was significantly lower in the postvaccine myocarditis group (5.7%) compared to conventional myocarditis (13.2%) with a weighted hazard ratio (wHR) of 0.55 (95% CI, 0.36-0.86). Hospital readmission for myopericarditis occurred in 3.2% of postvaccine cases, 4.0% of post–COVID-19 cases, and 5.8% of conventional cases. The all-cause mortality rate was 0.2% for postvaccine myocarditis, 1.3% for post–COVID-19 myocarditis, and 1.3% for conventional myocarditis.
Implications for Practice: Postvaccine myocarditis patients, primarily young males, experience fewer complications compared to conventional myocarditis, but long-term follow-up is still needed. These findings should guide future mRNA vaccine recommendations and clinical management for myocarditis patients.

Phase 3 RCT: Butantan-DV Dengue Vaccine is Safe and Shows 67.3% Efficacy Over 3.7 Years in Participants Aged 2–59 Years – Lancet Infect Dis
10 Aug, 2024 | 20:23h | UTCStudy Design and Population: This double-blind, randomized, placebo-controlled, phase 3 trial conducted in Brazil evaluated the efficacy and safety of the Butantan-dengue vaccine (Butantan-DV) in 16,235 healthy participants aged 2–59 years. Participants, who had not previously received a dengue vaccine, were randomly assigned to receive either a single dose of Butantan-DV or a placebo and were followed up for an average of 3.7 years.
Main Findings: The study found that Butantan-DV demonstrated 67.3% efficacy against virologically confirmed dengue (VCD) caused by any dengue virus serotype, with no cases of VCD caused by DENV-3 or DENV-4. The proportions of serious adverse events were similar between the vaccine and placebo groups, indicating that the vaccine was generally well tolerated.
Implications for Practice: The results support the potential of the Butantan-DV vaccine as an effective intervention for preventing symptomatic dengue, particularly from DENV-1 and DENV-2, across a broad age range regardless of dengue serostatus. Continued development and monitoring are warranted to confirm long-term efficacy and safety.
Phase 2 RCT: Preventive subcutaneous L9LS monoclonal antibody reduces malaria incidence by 66-70% in Malian children – N Engl J Med
7 May, 2024 | 15:31h | UTCThis phase 2 randomized clinical trial investigated the safety and efficacy of the monoclonal antibody L9LS in preventing Plasmodium falciparum infection and clinical malaria in children aged 6 to 10 years in Mali. The trial was structured in two parts: initial dose assessment in adults followed by a randomized, placebo-controlled test in children over a 6-month malaria season. A total of 225 children participated, divided equally among three groups to receive either 150 mg of L9LS, 300 mg of L9LS, or a placebo. Results demonstrated a significant reduction in the rate of P. falciparum infection—66% efficacy with the 150-mg dose and 70% efficacy with the 300-mg dose. Similarly, efficacy against clinical malaria was 67% with the 150-mg dose and 77% with the 300-mg dose. Both doses were well-tolerated with no safety concerns reported, underscoring the potential of L9LS as a preventative treatment against malaria in endemic regions.

RCT: No significant benefit of adjuvant prednisone for patients with cystic fibrosis with exacerbations unresponsive to antibiotics – Eur Respir J
6 May, 2024 | 06:32h | UTCThis randomized, double-blind, placebo-controlled trial investigated the effectiveness of adjuvant oral prednisone in enhancing lung function recovery in patients with cystic fibrosis (CF) experiencing pulmonary exacerbations (PExs) unresponsive to initial intravenous (IV) antibiotic treatment. The study involved 173 participants, with 76 not achieving more than 90% of their baseline forced expiratory volume in one second (ppFEV1) by Day 7 of antibiotic treatment and subsequently randomized to receive either oral prednisone (1 mg·kg−1 twice daily, up to 60 mg/day) or placebo for an additional 7 days. Results showed that 50% of the prednisone group and 39% of the placebo group recovered over 90% of their baseline ppFEV1 by Day 14. However, the difference was not statistically significant (11% difference; 95% CI -11, 34%; p=0.34). Additionally, prednisone did not significantly prolong the time to the next exacerbation compared to placebo. This study concludes that adjuvant oral prednisone does not significantly improve lung function recovery or delay subsequent exacerbations in CF patients not responding to initial antibiotic therapy.

RCT: Azithromycin fails to prevent moderate or severe chronic lung disease in preterm infants – Lancet Respir Med
6 May, 2024 | 06:28h | UTCThis randomized, placebo-controlled trial evaluated the effectiveness of azithromycin in preventing chronic lung disease (CLD) in preterm infants born at less than 30 weeks’ gestation across 28 UK neonatal intensive care units. A total of 799 infants were randomized to receive either intravenous azithromycin or a placebo. The primary outcome measured was survival without moderate or severe CLD at 36 weeks postmenstrual age. Results showed no significant difference between the azithromycin group (42% survival without CLD) and the placebo group (45% survival without CLD), with an adjusted odds ratio of 0.84 (95% CI 0.55–1.29, p=0.43). Pulmonary Ureaplasma spp colonization did not affect the treatment outcome. Given the lack of efficacy and the presence of several serious adverse events in the azithromycin group, the study concluded that azithromycin should not be recommended for preventing CLD in this population.

RCT | Tonsillectomy shown to be clinically and cost-effective in adults with recurrent acute tonsillitis
23 May, 2023 | 13:06h | UTCSummary: The NATTINA trial, a pragmatic multicentre, open-label, randomized controlled study, sought to compare the clinical and cost-effectiveness of conservative management versus tonsillectomy in adults with recurrent acute tonsillitis. Conducted across 27 UK hospitals, 453 participants aged 16 or older were randomly assigned to either undergo immediate tonsillectomy or receive standard non-surgical care.
The main finding was that participants in the immediate tonsillectomy group had fewer days of sore throat over a 24-month period than those in the conservative management group (median 23 vs. 30 days). After adjusting for site and baseline severity, the incident rate ratio of total sore throat days in the immediate tonsillectomy group was significantly lower than in the conservative management group (0.53, 95% CI 0.43 to 0.65, p < 0.0001). The most common adverse event related to tonsillectomy was bleeding, which occurred in 19% of participants.
The NATTINA trial is the largest to date assessing the clinical and cost-effectiveness of tonsillectomy in adults. The results indicate that immediate tonsillectomy is clinically effective and cost-effective for recurrent acute tonsillitis. However, patients should weigh the benefits of fewer sore throat days against the risks of surgery.
