From triggers to treatment: An epidemiological exploration of anaphylaxis in a lower middle-income area in Colombia.

In this cross-sectional, descriptive, and observational study conducted at Fundación Valle del Lili in Colombia, the clinical and sociodemographic characteristics of anaphylaxis were investigated in a cohort of 80 patients who sought medical care between January 2021 and December 2022. With a median age of 16 years and a notable prevalence among individuals aged below 18 years, the study revealed that 63.8% of patients had concomitant allergic diseases. Medications emerged as the primary triggers for anaphylaxis, followed by food. The mucocutaneous system was predominantly affected in 55% of cases, with respiratory involvement observed in 37.5%. Alarmingly, anaphylactic shock occurred in 17.5%, and 7.5% experienced biphasic anaphylaxis. Intramuscular adrenaline was administered in 88.8% of cases, with 75% of patients not receiving an allergy consultation upon discharge, and 52.5% lacking follow-up for allergy care. Considering that in Colombia epidemiological data on the clinical and sociodemographic aspects of anaphylaxis remain largely unknown, this study documents the features of anaphylaxis in both adult and pediatric populations and highlights the urgent need for improved awareness, timely evaluation by allergists, and comprehensive follow-up care for individuals experiencing anaphylaxis.
