Multivessel endovascular therapy for undiagnosed vascular type Ehlers-Danlos syndrome. Successful percutaneous transcatheter coil embolization of hepatic artery pseudoaneurysm with stenting of right renal and iliac arteries in emergency setting.

Among Ehlers-Danlos syndromes, the vascular type is the most severe because of its vascular complications. Transcatheter embolization of medium-sized arteries has become the first-line therapy for life-threatening hemorrhage. Ongoing multiple lesions causing hemorrhagic or ischemic complications in the acute phase can challenge patient management.

Pulmonary emphysema not combined with lung fibrosis in systemic sclerosis.

Interstitial Lung Disease (ILD) is a common finding of Systemic Sclerosis (SSc) mainly presenting in the form of Nonspecific Interstitial Pneumonia (NSIP) and deeply affecting patients' prognosis. Beside NSIP, other types of ILD have been reported. The most recently described pattern is the so-called Combined-pulmonary emphysema and lung fibrosis, characterized by the coexistence of both upper lobes centrilobular and paraseptal emphysema and lower lobes ILD.

Genetic Screening of Anderson-Fabry Disease in Probands Referred From Multispecialty Clinics.

Background: Anderson-Fabry disease (AFD) is a rare X-linked lysosomal storage disease, caused by defects of the alpha-galactosidase A (GLA) gene. AFD can affect the heart, brain, kidney, eye, skin, peripheral nerves, and gastrointestinal tract. Cardiology (hypertrophic cardiomyopathy), neurology (cryptogenic stroke), and nephrology (end-stage renal failure) screening studies suggest the prevalence of GLA variants is 0.

Risk of dissection in thoracic aneurysms associated with mutations of smooth muscle alpha-actin 2 (ACTA2).

Objective: To evaluate the prevalence and phenotype of smooth muscle alpha-actin (ACTA2) mutations in non-syndromic thoracic aortic aneurysms and dissections (TAAD).

Design: Observational study of ACTA2 mutations in TAAD.

Setting: Centre for Inherited Cardiovascular Diseases.

When should cardiologists suspect Anderson-Fabry disease?

Anderson-Fabry disease is a lysosomal storage disorder caused by α-galactosidase defects and progressive intracellular accumulation of globotriaosylceramide. The disease can be specifically treated with enzyme replacement therapy. Hemizygous men and heterozygous women can develop cardiac disease.

Co-existence of phenylketonuria and Fabry disease on a 3 year-old boy: case report.

Background: The co-existence of two genetically distinct metabolic disorders in the same patient has rarely been reported. Phenylketonuria (PKU) is an inborn error of the metabolism resulting from a phenylalanine hydroxylase deficiency. Fabry disease (FD) is an X-linked lysosomal storage disorder due to a deficiency of the enzyme alpha-galactosidase A.

The shortness of Pygmies is associated with severe under-expression of the growth hormone receptor.

The stature is a highly heritable trait controlled by genetic and environmental factors. The African Pygmies represent a paradigmatic example of non-disease-related idiopathic short stature (ISS), showing a similar endocrine profile of Caucasian individuals with ISS. Pygmy children show normal anthropometric and endocrine parameters until puberty, while adult Pygmies show normal baseline and post-stimulation serum growth hormone (GH) levels but low values of baseline serum GH-binding protein (GHBP) and insulin-like growth factor-I (IGF-I).

Transcriptomic and proteomic analysis in the cardiovascular setting: unravelling the disease?

Whole gene expression analysis through microarray technologies revolutionized the manner of identifying changes in biological events and complex diseases, such as cardiovascular settings. These new methodologies may scan up to 35 000 transcripts at once rather than screening a small amount of genes one at a time. The ability of microarrays to provide a broad insight into the disease process directly within the tissues provides a unique insight into the intracellular perturbations of the cell organization and function and sheds an entirely unique new perspective on the heart failure process.

Pro-inflammatory variants of DRB1 and RAGE genes are associated with susceptibility to pediatric type 1 diabetes: a new hypothesis on the adaptive role of autoimmunity.

Functional polymorphisms of two MHC genes (DRB1 and RAGE) were analysed in Italian pediatric patients with Type 1 diabetes and in a control group. The diabetic condition is related positively to the positive electric charge of the pocket 4 of pro-inflammatory DRB1 alleles (R = 0.5072, P = 0.

Two novel and one known mutation of the TGFBR2 gene in Marfan syndrome not associated with FBN1 gene defects.

TGF-beta-receptor 2 (TGFBR2) gene defects have been recently associated with Marfan syndrome (MFS) with prominent cardio-skeletal phenotype in patients with negative fibrillin-1 (FBN1) gene screening. Four mutations have been identified to date in five unrelated families. We screened TGFBR2 gene by direct automated sequencing in two adult patients diagnosed with MFS according to Ghent criteria, and in one girl clinically suspected as affected on the basis of a major cardiovascular criterion and skeletal involvement, all proven not to carry mutations in the exon-intron boundaries of FBN1 gene.

Identification of sixty-two novel and twelve known FBN1 mutations in eighty-one unrelated probands with Marfan syndrome and other fibrillinopathies.

Marfan Syndrome (MFS) is an autosomal dominant disorder of the connective tissue due to mutations of Fibrillin-1 gene (FBN1) in more than 90% of cases and Transforming Growth Factor-Beta-Receptor2 gene (TGFB2R) in a minority of cases. Genotyping is relevant for diagnosis and genotype-phenotype correlations. We describe the FBN1 genotypes and related phenotypes of 81 patients who were referred to our attention for MFS or Marfan-like phenotypes.
