ABSTRACT
BACKGROUND: The growing threat from pre-extensively drug-resistant tuberculosis (pre-XDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) poses a major public health concern in Latin America and the Caribbean (LAC). Therefore, this study aimed to summarize the available evidence on the prevalence of pre-XDR-TB and XDR-TB among patients with multidrug-resistant tuberculosis in LAC. METHODS: A systematic review was conducted in the following databases on June 3, 2023: PubMed, Scopus, Ovid Medline, Web of Science, Scielo and LILACS. We estimated pooled proportions using a random effects model (Dersimonian and Laird). The 95% confidence intervals (95% CI) were calculated using the binomial exact method (Clopper-Pearson Method). Subgroup (by time period and country) and sensitivity analyses were performed. RESULTS: Twenty-nine studies were eligible for qualitative synthesis and 27 for meta-analysis (n = 15,565). The pooled prevalence of XDR-TB in the study participants was 5% (95% CI: 3%-6%), while that of pre-XDR-TB was 10% (95% CI 7%-14%). Cuba (6%, 95% CI 0%-17%) and Peru (6%, 95% CI 5%-7%) had the highest pooled prevalence of XDR-TB. Regarding pre-XDR-TB, Brazil (16%, 95% CI 11%-22%) and Peru (13%, 95% CI: 9%-16%) showed the highest prevalence. CONCLUSIONS: The pooled prevalence of pre-XDR-TB and XDR-TB in LAC was 10% and 5%, respectively. Governments should strengthen drug-resistance surveillance and TB programs.

ABSTRACT Candida endocarditis is a very serious manifestation of candida infections, and it has increased in incidence over the past years. Of these, C. parapsilosis has been described as a cause of endocarditis in native valves of intravenous drug users and prosthetic valves. We report the case of a female that developed a cerebrovascular accident secondary to emboli from aortic prosthetic valve C. parapsilosis endocarditis, despite apparently normal echocardiography. She received antifungal therapy without surgical intervention.
RESUMEN La endocarditis por Candida spp. es una manifestación muy grave de las infecciones por este patógeno y su incidencia ha ido aumentando en los últimos años. La Candida parapsilosis se ha descrito como causa de endocarditis en válvulas nativas de usuarios de drogas intravenosas y prótesis valvulares. Presentamos el caso de una mujer que desarrolló un accidente cerebrovascular secundario a émbolos fúngicos procedentes de una prótesis valvular aórtica infectada por C. parapsilosis, a pesar de un ecocardiograma sin vegetaciones. La paciente recibió tratamiento antifúngico sin necesidad de intervención quirúrgica.
