[Neurologic disorders in children with chronic terminal renal insufficiency]. / Alteraciones neurológicas en niños con insuficiencia renal crónica terminal.

Neurological alterations are very frequent in children with end stage renal disease (ESRD). In order to assess the type of these complications, a neurological study was undertaken in 30 children with ESRD. Three of the patients had convulsions and hyperreflexia was the only clinical sign found in all the patients. Low serum levels of hemoglobin and calcium and high concentrations of phosphates, aluminum and parathyroid hormone were found in all cases, but correlations with any neurological alteration were not made. Abnormal EEG with slow waves in the occipital region were obtained in 23 patients. Sensorial hypoacusia was registered in 6 children who were previously treated with aminoglucosides. The cerebral tomography showed calcifications in three instances, but only in one patient were of clinical significance. In five, out of the 30 patients, cerebral atrophy was detected. In conclusion, assessment of the neurological condition is mandatory in children with ESRD before renal transplantation is performed, since the complication itself or the therapy may interfere with rehabilitation.
