Description of a novel AGPAT2 gene mutation (R159C) responsible for congenital generalized lipoatrophy type 1 (Berardinelli-Seip Syndrome)

Berardinelli-Seip congenital lipoatrophy type 1 (BSCL1) is a rare autosomal recessive disease caused by mutations in the AGPAT2 gene. This syndrome is characterized by near total absence of adipose tissue since birth, associated with the progressive development of metabolic complications. The AGPAT2 gene encodes for 1-acylglycerol-3phosphate-O-acyltransferase highly expressed in white adipocytes that catalyzes the acylation of lysophosphatidic acid to form phosphatidic acid, a...

Acquired generalized lipodystrophy associated with latent autoimmune diabetes mellitus in adults: a new metabolic phenotype

Ferrari Federica , Maranghi Marianna , Ceccarini Giovanni , Magno Silvia , Pelosini Caterina , Maffei Margherita , Vitti Paolo , Arca Marcello , Santini Feruccio

Introduction: Acquired generalized lipodystrophies (AGL) are rare syndromes characterized by complete loss of subcutaneous adipose tissue and very low serum leptin levels. AGL are complicated by severe insulin resistance, diabetes mellitus, dyslipidemia and fatty liver. In most patients evidence exists of an autoimmune etiology.Case report: We herein describe the case of a Caucasian woman who was diagnosed with lipodistrophy at 5 years of age, when she b...

Serum leptin and urine cortisol to cortisone ratio are correlated in familiar partial lipodystrophy type I (Kobberling Syndrome)

BackgroundIn lipodystrophy (LD) adipose tissue function is impaired, leading to a severe metabolic syndrome. Familiar Partial LD (FPLD) type I (Kobberling Syndrome) overlaps with Cushing’s syndrome phenotype. The latter and the metabolic impairment observed in FPLD1 may suggest a crosstalk between the HPA axis, assuming that leptin sensitivity is preserved in this context. We aimed to evaluate if leptin levels are associated with glucocorticoid acti...

Generalized lipodystrophy associated with delayed neuro-somatic development and multiple dysmorphisms in a neonate with a compound heterozygous missense mutation in the SYNE2 gene

Pelosini Caterina , Ceccarini Giovanni , Aretini Paolo , Lorenzoni Francesca , Magno Silvia , Caligo Maria Adelaide , Sessa Maria Rita , Ferrari Federica , Ghirri Paolo , Santini Ferruccio

Generalized lipodystrophies are extremely rare diseases. Despite remarkable progress in identifying genes responsible for the most common forms of genetic lipodystrophies, the molecular basis of disease in some patients with distinctive phenotypes remains unclear. We herein describe the case of a male patient born from non-consanguineous parent affected by a syndrome characterized by generalized lipodystrophy, psycho-somatic growth retardation, cleft palate, macroglossia, righ...

Obesity and expression of serotonin transporter (SERT) in human platelets

Marsili A , Santini F , Pelosini C , Betti L , Fabbrini L , Galli G , Ricco I , Baroni S , Italiani P , Fierabracci P , Giannaccini G , Pinchera A

Serotonergic transmission is involved in eating behaviour and body weight control. Comparison of SERT properties in blood platelets and serotonergic synaptosomes suggests that the human platelet can serve as an appropriate model for the transport, metabolism and release of serotonin by serotonergic neurons.Aim of this study was to evaluate SERT expression in platelets obtained from overweight or obese subjects (OB) as compared with normal weight healthy volunteers (C), and to ...

Objective: Treatment with metreleptin ameliorates hepatic steatosis in patients with lipodystrophy. The anti-steatotic effect of metreleptin is partially independent of its anorexic action, which suggests a direct effect of metreleptin on hepatic lipid metabolism. However, this mechanism is unknown. Based on previous findings in rodents, we hypothesized that metreleptin reduces hepatic lipid content by stimulating very-low density lipoprotein triglyceride (VLDL1-TG) secretion,...
