Background: Secretion of Wnt-proteins by adipose cells plays an important role in the control of adipogenesis. The Wnt-antagonist, dickkopf-1 (DKK-1), is secreted by human pre-adipocytes and influences adipocyte maturation and growth. DKK-1 mRNA increases 6 h after onset of human adipogenesis followed by an increase in DKK-1 protein. Of note, DKK-1 protein has been implicated also in bone remodeling pathways.Patients and Methods: In this study we measure...

Background and aims: Fat and bone are linked by a multitude of pathways supporting a skeleton appropriate for the mass of adipose tissue of the organism. We aimed to investigate the relations of adipose tissue hormones such as leptin, adiponectin, retinol-binding-protein-4 (RBP-4) and lipocalin-2 along with the low grade inflammation marker hs-CRP with markers of bone metabolism such as osteoprotegerin (OPG), receptor-activator of NF-κB ligand (RANKL), osteocalcin, C-term...

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare inherited disease characterized by mineralocorticoid resistance with subsequent salt wasting, hyperkalemia, metabolic acidosis, and elevated plasma renin and aldosterone levels.Patients and methods: We report a male newborn that presented with failure to thrive and sustained hyponatremia during his early postnatal period. He was conceived after IVF (twin pregnancy) and prematurely born by cesare...

Background: The optimal timing and appropriate first-line investigations for delayed menarche in an otherwise well teenager with fully developed secondary sexual characteristics is debatable.Case presentation: A 15 year-old female presented with parental concerns of cliteromegaly. Facial acne and primary amenorrhoea were also noted. Pubic hair development started at age 10 years and breast development age 12 years. Family history revealed delayed menarch...

Background: Diabetic ketoacidosis (DKA) is a severe and often the inaugural clinical manifestation of type 1 Diabetes (T1D). Diabetic nephropathy is one of the most devastating chronic complications of T1D and its’ early diagnosis is traditionally based on microalbuminuria.Objective and hypotheses: The aim was to investigate the possible associations between the initial clinical manifestations and the chronic complications of T1D.<p class="abste...

Introduction: Congenital Adrenal Hyperplasia (CAH) is an autosomal recessive disorder caused by pathogenic variants in seven genes involved in the cortisol and aldosterone biosynthetic pathway. The second most common cause of CAH, 11β-hydroxylase deficiency (11βOHD), is attributed to pathogenic variants in the CYP11B1gene encoding for the enzyme 11β-hydroxylase (11βOH).Case presentation: A thirteen-year-old g...

Introduction: CAH-X syndrome refers to a subset of Congenital adrenal hyperplasia (CAH) patients who display the hypermobility phenotype of Ehlers–Danlos syndrome (hEDS) due to the monoallelic/biallelic presence of a CYP21A2 deletion extending into the TNXB gene (chimeric TNXA/TNXB gene). To date, three different TNXA/TNXB chimeras have been described, CH-1 (presence of a TNXA-derived 120bp deletion in exon 35 of the <...

Obesity—defined as excess fat mass which impacts on physical health—is a complex and multifactorial disease where numerous environmental factors (overeating and/or reduced physical activity) act in concert with genetic factors. Understanding molecular mechanisms of obesity has rapidly improved in recent years due to the development of faster, more specific genetic screening tools (1). Rare genetic obesities are distinguished from more-common polygenic obesities where...

Background: Autoimmune polyglandular syndrome type 1 (APS-1) is &acy; rare multisystem disorder due to mutations in the autoimmune regulator gene (AIRE). APS-1 usually is characterized by a triad of hypoparathyroidism, primary adrenal insufficiency (PAI) and chronic mucocutaneous candidiasis. In the absence of the classic triad, the diagnosis becomes obscure and is often delayed.Case presentation: We report a 12 years ol...

Introduction: Noonan syndrome-Neurofibromatosis type 1 (NSNF) is a genetic disorder characterized with clinical features of both Noonan syndrome (NS) and neurofibromatosis type 1 (NF1). Recombinant human growth hormone (rhGH) has been widely used in NS patients as well as in some patients with NF1 but there are only a few published cases of rhGH treated NSNF patients. We report a patient with NSNF with short stature who started rhGH treatment with subsequent p...
