We encountered two children suffering from liver glycogenoses (GSD) over a period of 5 years (1992-1997) who presented with a demyelinating peripheral neuropathy diagnosed by electromyography (EMG) and nerve conduction studies (NCV). The aim of the study was to evaluate the involvement of muscle and motor nerve in children suffering from liver glycogenoses. In a cross-sectional study, 22 children suffering from liver GSD (with no current neurological symptoms) and 20 age- and sex- matched clinically free children (control group) underwent creatine phospho-kinase (CPK), EMG, and NCV studies. Abnormal EMG and/or NCV studies were found in 11 children. Six (27.27 per cent) were found to have axonopathy, three (13.63 per cent) demyelinating polyneuropathy, and two (9.1 per cent) had mixed axonal and demyelinating neuropathy. Two children with axonopathy had GSD type VI, another had GSD type IV, and three had GSD of undiagnosed type. Three of those having a demyelinating polyneuropathy had GSD type III, another had GSD type IV, and the last had GSD of undiagnosed type. None were found to have a cardiomyopathy or a myopathy on EMG. This is the first report of neuropathy associated with GSD types III, IV, and VI in children. It might be discovered by EMG and/or NCV studies in a clinically, neurologically normal child suffering from GSD, or present as an acute polyneuropathy.

Liver transplantation (LT) is the definitive treatment of end-stage liver disease. The long-term survival following LT spurred more interest in improving the quality of life of patients. This was a cohort study that included 23 pediatric liver transplant recipients who underwent LT due to hereditary or metabolic liver diseases. Bone health assessment was performed at their last follow up clinically (anthropometric measures), biochemically and radiologically (Dual Energy X-ray Absorptiometry [DEXA] scans). Poor bone health was defined as z-score <-1. Mean age at LT was 5.77 years (standard deviation [SD] 3.64) and 43% were males. Biliary atresia was the most common cause of end stage liver disease (35%). Mean age at follow up was 14 years (SD 5.48) and mean follow up was 8 years (SD 4.12 years). Eleven patients (48%) had poor bone health (osteopenia 22% and osteoporosis 26%). On univariate analysis, being on steroids at last follow up (odds ratio [OR] 13.2, 95% confidence interval [CI] 1.23-140.67, P = .03), weight at last follow up (OR 0.45, 95% CI 0.20-0.99, P = .04), platelets at last follow up (OR 0.98, 95% CI 0.96-s0.99, P = .02), hemoglobin at last follow up (OR 0.33, 95% CI 0.12-0.89, P = .03) were significantly associated with poor bone health. None of the variables were significant on multivariate analysis. At most recent follow up, 48% of patients demonstrated poor bone health by DEXA scans. More studies are required to evaluate predictors of poor bone health after LT in children.
