Plasma Neurofilament Light (NfL) in Patients Affected by Niemann-Pick Type C Disease (NPCD).

(1) Background: Niemann-Pick type C disease (NPCD) is an autosomal recessive lysosomal storage disorder caused by mutations in the NPC1 or NPC2 genes. The clinical presentation is characterized by visceral and neurological involvement. Apart from a small group of patients presenting a severe perinatal form, all patients develop progressive and fatal neurological disease with an extremely variable age of onset.

and effects of Ambroxol chaperone therapy in two Italian patients affected by neuronopathic Gaucher disease and epilepsy.

Gaucher disease (GD) is an autosomal recessive lysosomal storage disorder caused by mutations in the acid β-glucosidase encoding gene (), resulting in the deficient activity of acid β-glucosidase (GCase). To date, there is no approved treatment for the neurological manifestations of the disease. The role of Ambroxol as a chaperone for mutant GCase has been extensively demonstrated .

Improving diagnosis for rare diseases: the experience of the Italian undiagnosed Rare diseases network.

Background: For a number of persons with rare diseases (RDs) a definite diagnosis remains undiscovered with relevant physical, psychological and social consequences. Undiagnosed RDs (URDs) require other than specialised clinical centres, outstanding molecular investigations, common protocols and dedicated actions at national and international levels; thus, many "Undiagnosed RDs programs" have been gradually developed on the grounds of a well-structured multidisciplinary approach.

Methods: The Italian Undiagnosed Rare Diseases Network (IURDN) was established in 2016 to improve the level of diagnosis of persons with URD living in Italy.

Fabry cardiomyopathy: Gb3-induced auto-reactive panmyocarditis requiring heart transplantation.

Resistance to enzyme replacement therapy (ERT) is a major therapeutic challenge in Fabry disease (FD). Recent reports attribute to immune-mediated inflammation a main role in promoting disease progression and resistance to ERT. Aim of the study is to report a Gb3-induced auto-reactive panmyocarditis causing inefficacy of ERT and severe electrical instability, which required cardiac transplantation.

Data linkage analysis of giant cell arteritis in Italy: Healthcare burden and cost of illness in the Italian region of Friuli Venezia Giulia (2001-2017).

Giant cell arteritis (GCA) is the most common vasculitis in adults. However, comprehensive analyses of the healthcare burden are still scarce. The aim of the study is to report the healthcare burden and cost of illness of GCA in the Friuli Venezia Giulia (FVG) region of Italy, based on a data linkage analysis.

Vitamin D deficiency in a population of migrant children: an Italian retrospective cross-sectional multicentric study.

Background: Vitamin D is a hot topic in the scientific community. Its deficiency and the implications for the children's health became increasingly discussed during the last 20 years. The main aim of this retrospective study was to determinate the prevalence of vitamin D metabolism disorders in a population of adopted children and their risk factors.
