CD14 Tobacco Gene–Environment Interaction Modifies Asthma Severity & Immunoglobulin E Levels

CD14 gene
CD14 is part of the receptor complex for endotoxin, which is a component of tobacco smoke. The CD14 gene is located on chromosome 5q, a region previously demonstrated to be linked to asthma when stratified for smoke exposure. This study was designed to extend these findings by determining whether polymorphisms in the CD14 gene are related to this gene–environment interaction on asthma. Puerto Rican (n = 362 trios) and Mexican (n = 259 trios) families ascertained through a child with asthma were studied. (more…)

Feeding Lactose-Intolerant Baby: How to Give Milk-Free Infant Formulas

lactose intolerant baby

If the breast-fed baby is lactose intolerant (usually a temporary condition following intestinal infection at this age), mothers can continue to breast-feed, or pump their milk and treat it with lactase enzyme, until the baby’s symptoms stop. Details concerning feeding the lactose-intolerant infant are provided. There is no point in mothers’ eliminating milk and milk products from their diet to treat lactose intolerance in the baby, because their breast milk will contain 6 percent lactose (w/v) regardless of whether or not they consume cow’s milk.

Food Allergy Reactions: Triggers and Sources

food allergy reactions

In theory, any kind of food is having the capability to trigger food allergic reaction in our body. All foods contain molecules capable of triggering a response of the immune system. However, for many reasons—including both the structure of the food molecules and our body’s immunological responses—the foods that cause the majority of allergic reactions tend to be few in number.
