MicroRNAs, the endogenous mediators of RNA interference, interact with the renin-angiotensin-aldosterone system, regulate aldosterone secretion and aldosterone effects. Some novel data show that the expression of some microRNAs is altered in primary aldosteronism, and some of these appear to have pathogenic relevance, as well. Differences in the circulating microRNA expression profiles between the two major forms of primary aldosteronism, unilateral aldosterone-producing adenoma and bilateral adrenal hyperplasia have also been shown. Here, we present a brief synopsis of these findings focusing on the potential relevance of microRNA in primary aldosteronism.

Hypertension remains a global health challenge due to its high prevalence and association with premature morbidity and mortality. Aldosterone, a mineralocorticoid hormone, and its receptor, the mineralocorticoid receptor (MR), are highly implicated in hypertension pathogenesis. Aldosterone synthase is the sole enzyme responsible for producing aldosterone in humans.

Primary aldosteronism is characterised by the excessive production of aldosterone, which is a key regulator of salt metabolism, and is the most common cause of secondary hypertension. Studies have investigated the association between primary aldosteronism and genetic alterations, with pathogenic mutations being identified. This includes a glycine-to-arginine substitution at position 151 (G151R) of the G protein-activated inward rectifier potassium (K) channel 4 (GIRK4), which is encoded by the gene.

Primary aldosteronism (PA) is a common, salt-sensitive form of endocrine hypertension. Compared with essential hypertension (EH), PA is more susceptible to cardiorenal complications and metabolic risks. However, PA has a low screening rate and a poor response to mineralocorticoid receptor antagonists (MRAs).

Adrenal adenoma, which leads to increased production of the hormone aldosterone, commonly presents as hypertension and hypokalemia. Rhabdomyolysis as a result of hypokalemia secondary to primary hyperaldosteronism is a rare but important complication with only a few reported cases. Low potassium levels can disrupt the regulation of arteriolar musculature, leading to reduced blood flow to skeletal muscles.

This case report describes an adult man in his 50s with a history of type 2 diabetes and previously well-controlled hypertension, who presented with uncontrolled hypertension, muscle weakness and fatigue. Biochemical testing revealed hypokalaemia. There was no evidence of renal/renovascular disease.
