摘要
Objectives: This study aimed to assess the association between the appearance of intussusception in children andmedication intake in the immediately preceding period (2-15 days).
Methods: A case-crossover design was used. We selected cases of children admitted with a diagnosis of intussusception (International Classification of Diseases, Ninth Revision, 860) to the major hospitals in the city of Valencia, Spain, from 2006 to 2009. We then estimated the association between the episode of intussusception and the intake of prescription medication during the preceding 2, 7, and 15 days (case period) and for the same timewindow1, 2, 3, and 4months prior (control period). Data on previous drug administration were obtained from the Pharmaceutical Service Manager System.
Results: A total of 95 cases (65.3% boys and 34.7% girls) were selected; 76.6% were younger than the age of 2 years. The association between intussusception and prior drug use varied depending on the exposure window: 15-day odds ratio (OR), 1.45 (95% confidence interval [95% CI], 0.86-2.43); 7-day OR, 1.46 (95% CI, 0.80-2.67); and 2-day OR, 2.26 (95% CI, 1.10-4.64). These associations were greater for children aged younger than 2 years and were usually due to the recent administration (preceding 2 days) of antibiotics (OR, 8.00; 95% CI, 1.47-43.7).
Conclusions: Intussusception was more common among boys aged younger than 2 years. A positive and significant association was observed when drugs were administered 2 to 7 days before the onset of symptoms in children younger than the age of 2 years.
