PPI use linked with increased fracture risk in children

Proton pump inhibitor use was associated with a small but significant increase in fracture risk in a large Swedish registry–based cohort of children under 18 years.

The fracture incidence rates among 115,933 pairs of children under age 18 years matched based on propensity score and age were 20.2 versus 18.3 per 1,000 person-years among those who did and did not receive proton pump inhibitor (PPI) therapy, respectively (hazard ratio, 1.11), Yun-Han Wang of Karolinska Institute, Stockholm and colleagues reported in JAMA Pediatrics.

Increases in risk with PPI use were seen for upper-limb fracture (HR, 1.08), lower-limb fracture (HR, 1.19) and other fractures (HR, 1.51), but not head fractures (HR, 0.93). The risks increased nominally in tandem with cumulative duration of PPI use (HR, 1.08, 1.14, and 1.34 for 30 days or less, 31-364 days, and 365 days or more, respectively), the investigators found.

After subgroup and sensitivity analyses, Mr. Wang and associates stated that PPI use in children “was associated with a statistically significant 11% relative increase in risk of any fracture. The association was driven by fractures of upper limbs, lower limbs, and other sites; appeared to be mainly restricted to children 6 years and older; and seemed to be somewhat more pronounced with a longer cumulative duration of PPI use.”

“Risk of fracture should be taken into account when weighing the benefits and risks of PPI treatment in children, they concluded.

This study was funded by the Swedish Research Council and Frimurare Barnhuset Foundation; one coauthor was supported by a grant from the Strategic Research Area Epidemiology program at Karolinska Institutet. Two coauthors reported associations with pharmaceutical companies, and one of them with a health care data company. Dr. Wang and the remaining coauthors reported having no disclosures.
