Transaldolase (TALDO) deficiency is a newly recognized metabolic disease, which has been reported so far in 2 patients presenting with liver failure and cirrhosis. We report a new sibship of 4 infants born to the same consanguineous parents; all presented at birth or in the antenatal period with dysmorphic features, cutis laxa and hypertrichosis,(More)
In a personal series of 107 patients, we describe clinical presentations, methods of recognition and therapeutic management of inherited fatty acid oxidation (FAO) defects. As a whole, FAO disorders appear very severe: among the 107 patients, only 57 are still living. Including 47 siblings who died early in infancy, in total 97 patients died, of whom 30%(More)
There are almost one hundred inborn errors of metabolism which can start in the neonatal period, but less than 20 are amenable to treatment. In general, an extremely evocative clinical setting is the course of a full-term baby born after normal pregnancy and delivery who, after an initial symptom-free period deteriorates relentlessly for no apparent reason(More)
OBJECTIVE To evaluate the neurologic outcomes of neonates and infants suffering from persistent hyperinsulinemic hypoglycemia of infancy (PHHI). METHODS The neurologic development of 90 PHHI patients was studied retrospectively. Sixty-three patients were treated surgically and 27 were treated medically. Fifty-four patients were neonates, of whom 8 were(More)
We investigated respiratory chain (RC), tricarboxylic acid cycle (TCA) enzyme activities, and oxidative stress in the tissues of six patients with organic aciduria (OA) presenting various severe complications to further document the role of mitochondrial OXPHOS dysfunction in the development of complications. Two children with propionic acidemia (PA),(More)
A six-day-old girl was referred for severe hepatic failure, dehydratation, axial hypotonia, and both lactic acidosis and ketoacidosis. Biotin-unresponsive pyruvate carboxylase deficiency type B was diagnosed. Triheptanoin, an odd-carbon triglyceride, was administrated as a source for acetyl-CoA and anaplerotic propionyl-CoA. Although this patient succumbed(More)
Severe growth retardation and profoundly altered body composition are observed in children with systemic forms of juvenile chronic arthritis receiving glucocorticoids. The purpose of this study was to assess the effects of recombinant human GH (rhGH) on growth velocity (GV) and body composition studied by dual-energy X-ray absorptiometry, during a 1-yr(More)
OBJECTIVE To evauluate the relationship between propionic acidemia (PA) and cardiomyopathy. STUDY DESIGN We retrospectively compared clinical and metabolic results of patients with PA with and without cardiomyopathy. RESULTS Of 26 patients with PA who survived the first year of age, a dilated cardiomyopathy developed in 6 (group 1) at a median age of 7(More)
Mutations in the MUT locus encoding for the methylmalonyl-CoA mutase (MCM) apoenzyme are responsible for the mut forms of methylmalonic acidemia (MMA). To date, 49 different mutations have been identified in mut MMA. Only two frequent mutations have been reported in the Japanese population and in African-Americans. Here we report a new missense mutation(More)
Hypoglycemia occasionally results from oxidative phosphorylation deficiency, associated with liver failure. Conversely, in some cases of respiratory chain defect, the impairment in glucose metabolism occurs with normal hepatic function. The mechanism for this hypoglycemia remains poorly understood. We report here three unrelated children with hypoglycemia(More)
