MedicalResearch.com Interview with: Marie Lund MD, PhD student Department of Epidemiology Research KĂžbenhavn S | Denmark MedicalResearch.com: What are the main findings of the study? Dr. Lund: We found macrolide use in infants to be associated with a 30-fold increased risk of infantile hypertrophic pyloric stenosis (IHPS) with use during the first two weeks after birth and a lower, but significantly increased threefold risk with use during days 14 to 120. Similarly, there was a more than three-fold increased risk of IHPS associated with maternal macrolide use during the first two weeks after birth, but no increased risk with use thereafter. Finally, we found a possible modest association between maternal macrolide use during weeks 28 to birth and infantile hypertrophic pyloric stenosis. (more…)

Bjarke Feenstra, Ph.D. Senior Research Scientist Statens Serum Institut Artillerivej 5, 2300 Copenhagen S DenmarkMedicalResearch.com Interview with: Bjarke Feenstra, Ph.D. Senior Research Scientist Statens Serum Institut Artillerivej 5, 2300 Copenhagen S Denmark MedicalResearch.com: What are the main findings of the study? Dr. Feenstra: We discovered a new genome-wide significant locus for infantile hypertrophic pyloric stenosis (IHPS) in a region on chromosome 11 harboring the apolipoprotein (APOA1/C3/A4/A5) gene cluster and also confirmed three previously reported loci. Characteristics of the new locus led us to propose the hypothesis that low levels of circulating lipids in infants are associated with increased risk of IHPS. We addressed this hypothesis by measuring plasma lipid levels in prospectively collected umbilical cord blood from a set of 46 IHPS cases and 189 matched controls. We found that levels were on average somewhat lower in the children who went on to develop the condition. (more…)
