[How the recognition and treatment of primary aldosteronism could be improved?]


[Practically there were no randomized, controlled trials in the area of PA so far, but recently two such ones have appeared. In addition, both are paradigm- forming; yet not built into (yet?) the expert opinions. In the field of primary aldosteronism (PA), there is a sharp contrast between the world’s leading experts in many areas. There is consensus in respect that hypokalaemia, therapy resistance and vascular complications are more common in PA than in primary hypertension. According to prestigious studies, the ratio of surgically correctable cases can be around 5% of hypertension. However, only a tiny fraction of these cases are ever investigated even in the developed countries. Specific treatment might be reached more easily by a multi-speed approach applicable for domestic conditions in which one of the alternatives is the diagnostic process itself. In the latter, following aldosterone criteria are proposed: at screening greater than 15 ng/dl when associated with low renin, in the suppression test, for further testing (adrenal CT) a concentration above 5 ng/dl. This would provide a sufficient balance between sensitivity and specificity. Another solution could be the more widespread use of low dose spironolactone in resistant hypertension.]
