Abstract

Background. Median survival age in cystic fibrosis (CF) has increased in developed countries. Scarce literature exists about survival in Latin American, especially in Mexico. The aim of our study was to assess the median age of CF patients’ survival in Mexico over a 20-year period. Methods. We conducted a retrospective study, with all patients registered and followed in the CF Center in Monterrey, Mexico from 2000 to 2020. Median survival age was the primary outcome, assessed with the Kaplan-Meier analysis. Influence of clinical, biological, and demographic factors on survival were analyzed with the Cox regression model. Results. Two-hundred five patients were included. Median survival for the cohort was 21.37 years (95% CI 17.20 – 25.55). In the multivariate Cox regression model, low socioeconomic status (hazard ratio [HR] 4.21, 95% CI 2.43 – 7.27), chronic Pseudomonas aeruginosa (P. aeruginosa) infection at 6 years (HR 10.45, 95% CI 5.66 – 19.28), and pancreatic insufficiency (HR 3.13, 1.38 – 7.13) were independent risk factors for mortality. Conclusion. Median survival in Mexican patients with CF is lower than in high-income countries, and socioeconomic status plays a conspicuous role in the disparity. To increase patient survival for those residing in low-income countries, public health authorities must design policies that fully cover diagnosis and treatment strategies for the CF population.
