Peptide MC2R Antagonists as a New Potential Therapeutic Approach for Congenital Adrenal Hyperplasia

Current hormone substitution therapy of patients with congenital adrenal hyperplasia (CAH) is suboptimal and cannot mimic physiological daily rhythms of hormone secretion. As supra-physiological corticoid doses are necessary to avoid adrenal androgen excess, patients show substantially increased comorbidities such as hyperglycemia, arterial hypertension, reduced growth and osteoporosis. Moreover plasma ACTH is often inadequately suppressed, resulting in undesired excess adrena...

Osteoporosis in Triple A Syndrome: an Overlooked Symptom of Unexplained Etiolaogy

Dumic Miroslav , Rojnic Putarek Natasa , Kusec Vesna , Barisic Nina , Koehler Katrin , Huebner Angela

Background: Triple A syndrome (alacrima, achalasia, adrenal failure, progressive neurodegenerative disease) is caused by mutations in the AAAS gene which encodes the protein ALADIN. Osteoporosis seems to be an overlooked symptom in triple A syndrome.Objective and hypotheses: To evaluate etiology of osteoporosis in six male and four female patients with triple A syndrome.Method: X-ray, dual X-absorptiometry (DXA) of the lum...

Genetic Heterogeneity in Triple A Syndrome: Discrimination of the Classic Syndrome from Two Triple A-Like Syndromes

Huebner Angela , Reschke Felix , Kurth Ingo , Kutzner Susann , Utine Eda , Hazan Filiz , Landgraf Dana , Hubner Christian A , Koehler Katrin

Background: Triple A syndrome is a rare autosomal recessive disorder characterized by adrenal failure, alacrima, achalasia, and a variety of neurological features. In 70% of the families it is caused by mutations in the AAAS gene. Linkage analyses indicated genetic heterogeneity and exome sequencing revealed two further genes causing triple A-like syndromes.Objective and hypotheses: To summarise the genotypes and phenotypes of classic triple A s...

Introduction: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires appropriate diagnosis and treatment. The most common cause of PAI is congenital adrenal hyperplasia (CAH), but other well-established aetiologies include metabolic and autoimmune disorders, and physical damage. Mutations in more than 30 genes have now been associated with PAI, with considerable biochemical and phenotypic overlap. It is therefore importan...
