Impact of nutritional rehabilitation on gastroesophageal reflux in neurologically impaired children.

The impact of nutritional rehabilitation on gastroesophageal reflux (GER) in 10 malnourished neurologically impaired children (NIC) was studied (mean age, 9.1 +/- 3.1 years). None of the children had an antireflux procedure (ARP), and all were fed exclusively through a percutaneous endoscopic gastrostomy (PEG). Malnutrition was defined as triceps skin fold thickness (TSF) below the fifth percentile for age and sex. GER was established using standard criteria for a 24-hour pH probe study. All children were treated with an H2 antagonist and a prokinetic agent, along with aggressive nutritional rehabilitation. When TSF was > or = 50th percentile, medications were stopped, and the 24-hour pH probe study was repeated. The mean weight gain was 8.8 +/- 3.7 kg over 8.4 +/- 2.3 months. The 24-hour pH probe study showed marked improvement after nutritional rehabilitation in six of 10 children. These children remained asymptomatic throughout long-term follow-up, without the use of medications. Two children had abnormal pH probe results and worsening clinical symptoms when taken off medications after nutritional rehabilitation. They were reexamined after reinstituting the prokinetic drug; results of the pH probe study were normal, and there was no clinical symptomatology. The patients were then given long-term medication. Two children (one with erosive esophagitis and one with persistent symptoms) underwent ARP. We conclude that despite accompanying GER, successful nutritional rehabilitation can be achieved in malnourished NIC, using PEG feeding and antireflux medication. Although some NIC with GER may need an ARP or long-term medication, in most malnourished NIC nutritional rehabilitation is associated with resolution of GER.
