Abstract: | Most children with cystic fibrosis (CF) show persisting steatorrhoea even when treated with pancreatic enzyme. As a low duodenal pH could be responsible for this persisting fat loss, we evaluated the effects of a proton-pump inhibitor (lansoprazole) on both steatorrhoea and growth parameters in 15 CF patients, aged 3.1–22.6y. Acid steatocrit, anthropometry and dual-energy X-ray absorptiometry were used to evaluate steatorrhoea and the nutritional status before, during and 3 months after stopping lansoprazole treatment (15mg/d for 3 months). Mean ± SD acid steatocrit values decreased from 37.1 ± 8.8% to 28.5 ± 10.6% ( p = 0:02). Significant mean Z -score improvements were found for weight (+0:14; p = 0:02), height (+0:15; p = 0:03), subscapular (+0:61; p = 0:003), supra-iliac (+0:8; p = 0:002) and the sum of the four measured skinfolds (+0:61; p = 0:002). Z -scores deteriorated again after stopping lansoprazole. Fat mass and bone mineral content increased significantly on lansoprazole ( p = 0:008 and p = 0:005, respectively). We conclude that lansoprazole as adjuvant therapy significantly improves both steatorrhoea and the nutritional status in CF children who maintain steatorrhoea while on pancreatic enzymes. |
