The apparent mineralocorticoid excess syndrome (AME) is a rare autosomal recessive disorder due to the deficiency of 11?-hydroxysteroid dehydrogenase type 2 enzyme (11beta-HSD2). The 11beta-HSD2 enzyme, encoded by HSD11B2 gene, metabolizes active cortisol in cortisone. Mutations on HSD11B2 gene affect the enzyme activity by leading to an excess of cortisol, which causes its inappropriate access to mineralocorticoid receptor. Therefore, cortisol will bind mineralocorticoid receptor. The human HSD11B2 gene maps to chromosome 16q22 and consists of five exons encoding a protein […]

Arterial hypertension is associated with high morbidity and mortality indices and constitutes a major health problem worldwide, specially due to its high prevalence and low rate of control with the standard treatment. This problem can be explained, at least in part, because we still use empiric measures when choosing treatment options, instead of a rational approach for each case. The determinants of the hypertension remain unknown in the majority of patients and is designated as essential or primary hypertension. Hypertension […]
