Objectives: Undernourishment is common in children with cerebral palsy (CP), but the reasons are unknown. We previously reported elevated levels of immunoglobulin (Ig) A and IgG antibodies against gliadin (AGA) and tissue transglutaminase (tTG) in 99 children and young adults with CP without characteristic findings of gluten enteropathy in small bowel biopsies. Our aim was to perform a case-control study of IgG antibodies against other dietary antigens, AGA, anti-tTG, and IgE antibodies against wheat and gluten. less thanbrgreater than less thanbrgreater thanMethods: Sera from 99 cases with CP and 99 healthy, age-and sex-matched controls were analysed with fluorescence enzyme-linked immunosorbent assay for detection of IgG antibodies against beta-lactoglobulin, casein, egg white, IgG-and IgA-AGA, IgA-anti-tTG, and IgE antibodies against gluten and wheat. less thanbrgreater than less thanbrgreater thanResults: Compared with controls, the odds ratio in cases with CP for having elevated levels of IgG antibodies against beta-lactoglobulin was 17.0 (95% confidence interval [CI] 2.3-128), against casein 11.0 (95% CI 2.6-46.8), and against egg white 7.0 (95% CI 1.6-30.8). The IgE responses for wheat/gluten were generally low. The tetraplegic and dyskinetic CP subtypes had significantly higher frequencies of elevated levels for all of the tested antibodies except IgG against egg white, and IgA-anti-tTG. A significantly lower weight was seen in cases with CP with positive versus negative serology. less thanbrgreater than less thanbrgreater thanConclusions: Elevated levels of IgG against dietary antigens were more frequent in the CP group compared with controls, and particularly in the tetraplegic and dyskinetic CP subtypes with the most severe neurologic handicap and undernourishment. Hypothetically, malnourishment may cause increased intestinal permeability and thus immunization against dietary antigens.
