Metabolic disturbances in patients with cerebral palsy and gastrointestinal disorders.

Under nutrition and growth failure are common findings in children with cerebral palsy (CP) and neurologically impairments. Electrolyte and micronutrient abnormalities have also been documented. Gastrointestinal (GI) diseases like gastro esophageal reflux disease (GERD), feeding difficulties and constipation have been associated with increased frequency of these derangements. The goal of this study was to determine the prevalence of malnutrition, metabolic and electrolyte abnormalities in pediatric patients with cerebral palsy and gastrointestinal disorders. A retrospective review of 172 medical records was performed out of which 45 subjects did not have any GI problem, 69 patients had constipation and 58 patients either had GERD, esophagitis, gastrostomy and feeding difficulties. Data collected included: weight, length and body mass index, pre-albumin, albumin, vitamin D, potassium, chloride, bicarbonate, calcium, magnesium (Mg), phosphorus. The results demonstrate a significant difference (p = 0.0126) in the values of albumin in children with CP with GI disorders vs. those without. Additionally, a significant difference (p = 0.0129) was found in Mg levels between CP children with constipation vs. GERD/esophagitis/feeding issues/gastrostomy. Results suggest that children with CP and GI disorders have decreased levels of albumin, but normal pre-albumin. The mechanism for this is not completely clear and although we acknowledge importance of nutritional intake for albumin level support, other mechanisms such as low grade chronic inflammation and increased gut and vascular permeability may play a role. The lower levels of Mg in children with CP and constipation could be secondary to the use of laxatives. Further prospective studies looking at nutritional protein intake, gut and vascular permeability and laxative use in this patient population are important for future optimization of health care management.
