GERD confirmed but PPIs aren’t working?Laparoscopic fundoplication is an effective treatment for GERD. However, due to its adverse effects (dysphagia, bloating, flatulence) and risk of treatment failure or breakdown within 5 to 10 years, it should be reserved for those poorly managed with PPIs.2,13,19
Considerations in pregnancy.GERD is reported by 40% to 85% of pregnant women,20,21 and its clinical presentation, diagnosis, and treatment are similar to that of nonpregnant adults.21 If lifestyle modification is not effective, pharmacologic therapy may be considered. Often, lifestyle modifications and antacids followed by the addition of sucralfate will be used first given the lack of systemic effects. H2RAs can be used next based on long-term historical use and reported safety.21 As with nonpregnant patients, PPIs are more effective than other medical therapies. If PPIs are used, dexlansoprazole, lansoprazole, pantoprazole, and rabeprazole are preferred. Omeprazole and esomeprazole are typically avoided due to findings of embryonic and fetal mortality in early animal studies, although subsequent human studies have noted no teratogenicity.2,20,21
Considerations in children. As with adults, findings in the history and exam are sufficient to diagnose and initiate treatment of GERD in children, provided there are no warning signs (eg, bilious vomiting, GI bleeding, consistent forceful vomiting, fever, lethargy, hepatosplenomegaly, bulging fontanelle, macro- or microcephaly, seizures, abdominal tenderness/distention, or genetic/metabolic syndromes). Lifestyle changes are first-line treatment, followed by medication. Acid suppressants are preferred, with PPIs showing superior efficacy compared with H2RAs.15 Some PPIs (omeprazole, lansoprazole, and esomeprazole) have US Food and Drug Administration (FDA) approval beginning at age 1 year, while rabeprazole has FDA approval beginning at age 12.22 As in adults, if PPIs are ineffective, consider alternative diagnoses.15,22
Helicobacter pylori infection
H pylori is a gram-negative spiral-shaped bacterium found in the stomach of humans and other mammals. It survives the acidic environment by metabolizing urea into alkaline ammonia and carbon dioxide. H pylori infection increases the risk of peptic ulcer disease, gastric cancer, iron deficiency anemia, and immune thrombocytopenia. It may be associated with dyspepsia, increased ulcer risk with use of an NSAID, and chronic gastritis.9 Infection with H pylori can decrease the risk of GERD.2 The bacterial infection causes atrophic gastritis and subsequent hypochlorhydria, which then diminishes the acidity of the reflux contents.19 There is no link between H pylori infection and BE.1
TABLE 12,9-11 shows those at highest risk of H pylori. The estimated prevalence of infection is 40% to 48%23 worldwide but lower in North America, at 32% to 42%.24H pylori is often acquired in childhood, and risk of infection is more likely if the parents (particularly mothers) are infected.9
