MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The background is that mothers are often concerned that something they did contributed to their children developing food allergies. Many will relate that they ate a lot of one specific food allergen while pregnant, and question how this could have impacted their unborn child. We realized that we hear a lot of anecdotal stories in clinic, but were not sure how frequently mothers try to alter their diet in the hopes of preventing food allergy in their children. We also were not sure where families get information or guidance on this topic. Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: People who have the genetic disease cystic fibrosis have increased sticky secretions in their lungs that put them at risk for repeated bacterial infections. They often will receive courses of intravenous antibiotics to treat more severe or difficult-to-treat infections associated with decreased lung function. However, not all patients fully recover their lung function after antibiotic treatment, despite directing antibiotic therapy toward the specific bacteria thought to be causing the infection. The goal of this study was to determine if the pharmacokinetics of commonly used antibiotics was associated with recovery of lung function.

First, we found that patients with therapeutic blood levels of beta-lactam antibiotics had better lung recovery than patients with sub-therapeutic levels of these antibiotics.

Second, we found that using higher antibiotic dosing according to Cystic Fibrosis Foundation guidelines was not sufficient to predict which patients would have therapeutically meaningful blood levels of antibiotics. Continue reading
