Methylmalonic aciduria with homocystinuria: biochemical studies, treatment, and clinical course of a Cbl-C patient.

A patient with infantile onset methylmalonic aciduria and homocystinuria (Cbl-C mutant) is described. Therapy with hydroxycobalamin, folate and vitamin B6 improved his condition. As hypomethioninaemia and homocystinaemia persisted, he was treated with intramuscular methylcobalamin, but without success. Treatment with betaine started at 25 months of age, normalized plasma methionine and elicited disappearance of homocystinaemia. Results of biochemical studies in cultured fibroblasts paralleled those described for other Cbl-C patients except that methylmalonyl-coenzyme A mutase activity in disrupted fibroblasts was in the normal range.

A new family affected by the syndrome of hyperornithinaemia, hyperammonaemia and homocitrullinuria.

We have reported three cases of hyperornithinaemia associated with hyperammonaemia and homocitrullinuria (HHH). They deal with two brothers and a sister from a family where the parents and four other children are healthy on clinical and biochemical examination. The biochemical findings in our patients indicate the existence of a defect in the transport of ornithine into the mitochondria. Cultured skin fibroblasts from two of these patients incorporated six times less [14C]ornithine into protein as compared to control cells. The most characteristic sign of the clinical picture is the progressive spastic paraparesis found in one of the cases. Ornithine supplementation and restricted protein intake may be useful in the treatment of this syndrome since after three years of treatment the clinical response was favourable and the patients showed no adverse clinical effects.
