ABSTRACT
BACKGROUND: Median survival age in cystic fibrosis (CF) has increased in developed countries. Scarce literature exists about survival in Latin America, especially in Mexico. The aim of our study was to assess the median age of survival in CF patients and the impact of risk factors 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 Kaplan-Meier analysis. The influence of clinical, biological, and demographic factors on survival was analyzed with Cox regression model. RESULTS: Two-hundred five patients were included. Median survival for the cohort was 21.37 years (95% confidence interval [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 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-middle income countries, public health authorities must design policies that fully cover diagnosis and treatment strategies for the CF population.

La invaginación intestinal ocurre cuando un segmento proximal de intestino se repliega dentro de la luz de un segmento distal adyacente y provoca obstrucción intestinal. Es una causa común de abdomen agudo en los dos primeros años de la vida, pero raro en niños mayores. Un varón de 16 años, con diagnóstico de fibrosis quística, se presentó con un cuadro compatible con síndrome de oclusión intestinal distal. Consultó a la clínica con dolor abdominal y una masa palpable en el hipocondrio derecho. Se realizó ecografía abdominal y tomografía de abdomen contrastada, que demostraron invaginación íleo-colónica con signos de isquemia intestinal, necrosis y neumatosis de la pared intestinal. Fue intervenido: se realizó resección del íleon terminal y hemicolon derecho, y se detectó una tumoración en ciego. La invaginación íleo-colónica es una causa rara de abdomen agudo en pacientes adolescentes con fibrosis quística y puede estar asociada a una causa orgánica subyacente.
Intestinal intussusception occurs when a proximal segment of the intestine telescopes into the lumen of an adjacent distal segment, causing intestinal obstruction. It is a common cause of acute abdomen in the first two years of life, but rare in older children. A 16-year-old male with a diagnosis of cystic fibrosis presented with symptoms compatible with distal intestinal occlusion syndrome. He came at the cystic fibrosis clinic with a 5-day evolution of abdominal pain and a palpable mass in the right hypochondrium. Abdominal ultrasound and abdominal contrasted tomography were performed demonstrating ileo-colonic invagination with signs of intestinal ischemia, necrosis and pneumatosis of the intestinal wall. He underwent surgery with resection of the terminal ileum and right hemicolon, ana tumor in the caecum was found. This is a rare cause of acute abdomen in young patients with cystic fibrosis and may be associated with an underlying organic cause.
