Case Report: Two years of compassionate use with Olipudase-alfa in a child with neurovisceral acid sphingomyelinase deficiency.

Acid sphingomyelinase deficiency (ASMD) is a rare, progressive lysosomal storage disorder resulting from a deficiency in acid sphingomyelinase, leading to sphingomyelin accumulation and multi-organ damage. ASMD presents a broad phenotypic spectrum with a continuum of severity, making it challenging to predict the phenotype in very young children and differentiate between acute and chronic neurovisceral disease. No disease-specific treatments existed for ASMD.

Positive Clinical, Neuropsychological, and Metabolic Impact of Liver Transplantation in Patients With Argininosuccinate Lyase Deficiency.

Liver transplantation (LTx) is increasingly used in Urea Cycle Defects (UCDs) to prevent recurrent hyperammonemia and related neurological irreversible injury. Among UCDs, argininosuccinate lyase deficiency (ASLD) has a more complex phenotype than other UCDs, with long-term neurocognitive deficits. Therefore, the role of LTx in ASLD is still debated.

Congenital Hyperinsulinism of a Large Italian Cohort: A Retrospective Study.

Introduction: To evaluate and describe the diagnostic process, medical, nutritional, and surgical approach, and neurological outcome, we report data from a large Italian cohort of patients with congenital hyperinsulinism (CHI).

Methods: We retrospectively analyzed 154 CHI patients admitted to Ospedale Pediatrico Bambino Gesù from 1985 to 2022.

Results: Hypoglycemia occurred within the first year of life in 85.

Availability of psychological resources for parents receiving communication of positivity at newborn screening for metabolic diseases in Italy.

Receiving information in the case of a positive or false-positive expanded newborn screening (ENBS) result for metabolic diseases is a stressful event. The availability of psychological support to families is crucial across the different communication steps and is recommended by different guidelines and position papers. However, more information is needed about the availability of psychological resources in the ENBS process.

The impact of liver transplantation on health-related quality of life in (acute) intoxication-type inborn errors of metabolism.

Organic acidurias (OAs), urea-cycle disorders (UCDs), and maple syrup urine disease (MSUD) belong to the category of intoxication-type inborn errors of metabolism (IT-IEM). Liver transplantation (LTx) is increasingly utilized in IT-IEM. However, its impact has been mainly focused on clinical outcome measures and rarely on health-related quality of life (HRQoL).

Ketogenic diet as elective treatment in patients with drug-unresponsive hyperinsulinemic hypoglycemia caused by glucokinase mutations.

Background: Hyperinsulinemic hypoglycemia (HI) is the most frequent cause of recurrent hypoglycemia in children. Despite diagnostic and therapeutic advances, it remains an important cause of morbidity, leading to neurological complications, such as psychomotor retardation and epilepsy. Patients with diffuse drug-unresponsive HI manifest neurological impairment and neurobehavioral problems, even though surgically treated with a near-total pancreatectomy.
