Background: Lipodystrophy syndromes comprise a large group of extremely rare diseases characterized by loss or dysfunction of adipose tissue. Due to their extreme rarity and variability, research in the field of lipodystrophy is difficult for single centres warranting larger co-operations.Methods: Therefore, the European Consortium of Lipodystrophies decided to found an international registry in 2016. This registry is ba...

Background: Mutations in the PPARG gene, encoding peroxisome proliferator-activated receptor-gamma (PPARG) are associated with Familial lipodystrophy type 3. PPARG regulates fatty acid storage and glucose metabolism. The genes activated by PPARG stimulate lipid uptake and adipogenese by fat cells. In cases of lipodystrophy and defects of adipogenesis lipoid accumulates ectopically in the liver, skeletal muscle, pancreas and cardiovascular tissues and impairs the function of th...

Leptin is a type I cytokine and belongs to the long-chain helical cytokine subfamily just as GH, IL-6 and G-CSF. Leptin is produced mainly in white adipose tissue and thereby reflects body energy stores. Leptin serum concentrations are high in obese and low in underweight individuals or in those with low body fat e.g. in athletes and in patients with lipodystrophy. The leptin/leptin receptor system is crucial for the regulation of body weight. Rare homozygous mutations in the ...

Endocrine disorders are the most common causes of secondary hypertension. Early diagnosis and treatment is crucial for prevention of cardiovascular complications. Several rare but important entities like Cushing’s syndrome and pheochromocytoma/paraganglioma can cause endocrine hypertension, in contrast to primary aldosteronism, which is quite frequent. Definition, classification and prevalence: With a prevalence of 6% in unselected patients with hypertension, 5 to...

Background: Hypogonadism has been associated with cardiovascular disease. However, little is known about the cardiovascular impact of hypogonadism during development. Using hypospadias as a surrogate of hypogonadism, we investigated whether hypospadias is associated with vascular dysfunction during childhood and whether it is a risk factor for adult cardiovascular disease.Methods: Our human study spanned molecular mechan...

Newer studies have indicated that vitamin D has more widespread effects than the classical effects on bone and calcium-phosphate homeostasis. The presence of the vitamin D receptor (VDR) in the testis and male reproductive tract indicates a role for vitamin D in male reproduction. Indeed, vitamin D deficiency and global knock out models of VDR or CYP27B1 in rodents have shown that vitamin D and calcium are important regulators of male reproductive function. Several groups have...

Background: Although differences in pubertal timing alters frequency of indicators of attained stature at the extremes, its magnitude is unknown across ethnic groups of US youths.Methods: We performed analyses of anthropometry and Tanner staging data of 3206 cross-sectional national sample of youths ages 8–18y (53% male (n=1606), 72% Non-Hispanic White (NHW), 9% Mexican American (MA) and 19% Non-Hispanic Black (NHB). Specialized Tanner-stag...

Background: Stunting is a common reason for consultation in pediatrics, several etiologies are responsible, although endocrine causes is rare, it is important to make the diagnosis in order to provide early adequate treatment. however the treatment by rGH is usually well tolerated, side effects should be known, including the possibility of retinal edema revealing intracranial hypertension.Objective and hypotheses: Our purpose is to report a side effect o...

Our patient was a 19-year-old female who was referred for evaluation of secondary amenorrhea and underdeveloped secondary sexual characteristics, having undergone her first and only menstrual cycle at age 16. She had experienced four episodes of hypoglycemia during her childhood; two were associated with seizure activity. She was evaluated by endocrinology after her second episode of hypoglycemia at 3 years of age and no cause could be identified. She also had learning difficu...

Introduction: Aromatase excess syndrome (AEXS) is a rare, autosomal dominant disorder, characterized by enhanced extraglandular aromatization of androgens and estrogen excess. Genomic rearrangements in chromosome 15q21 are found to result in overexpression of the aromatase gene CYP19A1. In males it is characterized by pre- or peripubertal gynecomastia, hypogonadotropic hypogonadism, advanced bone age and short adult height. Only a few female patients have been...
