68 Ga-pentixafor is a radionuclide imaging ligand specifically targeting CXCR4 ( 173 ). In 63 patients with PA who were treated surgically, 68 Ga-pentixafor PET-CT was noninferior to AVS in diagnosing lateralizing PA ( 174 ).

Suppressed vs Unsuppressed Renin in Individuals With Primary Aldosteronism Receiving Primary Aldosteronism–Specific Medical Therapy Background Although aldosterone-directed medical therapy has been shown to be beneficial in primary aldosteronism (PA), the op - timal approach to dosing and surveillance is uncertain.

Whether renin should be used to guide treatment has been considered in prior studies and by consensus groups. The premise of using renin as a biomarker of PA-specific medical therapy stems from the general knowledge of the physiology of endocrine hormone excess (ie, decline in hormone excess or activity is reflected in...

Since PA is characterized and diagnosed by aldoster - one production despite suppression of renin and angiotensin II, a rise in renin induced by aldosterone-directed medical therapy should reflect the reversal of PA pathophysiology that may portend improved clinical outcomes ( 175 ).

There were no statistically significant differences in MACEs (eg, ischemic heart disease, heart failure) in the meta-analysis.

In this regard, the addition of renin measurements does not pose a substantial increase in resource utilization. However, the add - itional costs of measuring renin may be a limiting factor or pro - hibitive to some clinicians and increase health disparities.

In balance, targeting a rise in renin may be associated with a lower risk of death, stroke, and atrial fibrillation, but the pooled analysis did not demonstrate statistically significant re - duction in the risk for MACEs.

The summary of sev - eral observational studies suggests that this practice is associ - ated with statistically lower risks of death and atrial fibrillation as well as a lower number of antihypertensive med - ications and risk for hypokalemia.

Importantly, the primary clinical objective of MRA therapy remains normalizing BP with the fewest number of medications (and normalizing po - tassium, when applicable); however, achieving a rise in renin is suggested as an additional objective that reflects a better prognosis ( 175 ).

Caveats to this approach include that this evidence stems from observational studies susceptible to bias and residual confounding, that there is no direct evidence to dictate what renin threshold to target as optimal, that this approach may not be possible or feasible or necessary in all individuals, that there are dif...

For these rea - sons, we suggest focusing on dose intensification of MRA therapy to raise renin, particularly in individuals whose BP is not controlled. Once BP is controlled, non-MRA medica - tions can be lowered or removed, when possible, thus allow - ing further increases of MRA dosing and attempts to raise renin ( ...

Furthermore, interpretation of renin levels may be hampered in individuals concomitantly receiving other medications that affect renin levels (eg, β -adrenergic blockers that lower renin or renin – angiotensin – aldosterone system [RAAS] inhibitors that may raise renin in synergy with MRAs).

The ability to produce and secrete renin may be im - paired with advanced CKD and higher MRA doses, which may increase the risk for hyperkalemia. As such, targeting an increase in renin in CKD may not always be a feasible or practical clinical objective.

However, since the nonsteroidal MRA finerenone has been shown to reduce adverse cardiovascular and kidney outcomes in 3 large randomized controlled trials (RCTs) of individ - uals with diabetes and CKD or heart failure ( 176-178 ), it is reasonable to treat individuals with PA and CKD with MRAs as long as serum potassi...

When encountering hyperkalemia in CKD, the use of concur - rent diuretics, sodium-glucose cotransporter (SGLT2) in - hibitors, and patiromer/novel potassium binders have all been shown to mitigate the risk of MRA-induced hyper - kalemia in RCTs ( 179 , 180 ).

• Individuals taking medications that influence renin: The use of some concurrent medications may confound the in - terpretation of renin. β -Adrenergic blockers can lower re - nin secretion; therefore, individuals on high doses may not manifest an increase in renin with MRAs.

High dietary so - dium intake can lower renin, whereas a sodium-restricted diet can increase renin ( 181 ); however, most of the global population consumes a relatively high dietary sodium con - tent known to expand intravascular volume and put downward pressure on renin.

A serum cortisol > 1.8 μ g/dL (50 nmol/L) suggests autonomous cor - tisol secretion (ACS). • For individuals with mild ACS, measuring plasma metanephrine during adrenal venous sampling (AVS) may help lateralize both aldosterone and cor - tisol secretion although further research is needed.

However, issues with selectivity of adrenal vein catheteriza - tion and lateralization of aldosterone production have not been reported in all studies ( 183 ), possibly because AVS inter - pretation was mainly affected in individuals with post- dexamethasone cortisol more than 5 ug/dL (138 nmol/L) ( 204 ).

• Furthermore, an understanding of normal adrenal cortisol secretion will reduce confounding in the interpretation of AVS results. Repeating AVS due to uninterpretable results is much more expensive ( ∼ $2000-3000 USD) than doing a 1-mg dexamethasone suppression test ( ∼ $20) and plan - ning AVS accordingly.

• Individuals rarely decline the dexamethasone suppression test in clinical practice. They may occasionally experience adverse effects from the dexamethasone, but these effects are transient, as the dose of dexamethasone is low and the medication is given only once.

The potential for harm from doing the dexamethasone suppression test is low and relates mainly to unnecessary investigations for Cushing syndrome. Therefore, the panel concluded that the balance of effects probably favors the intervention and that the test is feasible, accessible, and cost-effective.

Technical remarks: • The recommendation is driven by the availability and low cost of spironolactone vs other MRAs; however, all MRAs, when titrated to equivalent po - tencies, are anticipated to have similar efficacy in treating PA.

However, the doses of the medications were not renin-guided to ensure dose-equivalent MR blockade. There were no statistically significant differences in achieving BP control, control of hypokalemia, and SBP level.

After completion of the systematic review, but prior to publication of these guidelines, a new study comparing short-term finerenone and low-dose spironolactone in PA was published demonstrating comparable blood pressure – lowering efficacy and effects upon serum potassium and renin concentration ( 213 ).

Two systematic reviews/meta-analyses were found that compared spironolactone with eplerenone or canrenone ( 214 , 215 ). One meta-analysis of 14 studies and including 3745 individuals using spironolactone for non-PA indications showed a male gynecomastia incidence rate of 7.9% vs 0.6% among placebo users (OR:

8.39 [5.02-13.99]), although this was still less than that observed in users of anti-androgens or ris - peridone ( 214 ). Among users of MRAs or placebo for heart fail - ure, spironolactone had a relative odds of 8.44 (3.9-18.2) vs eplerenone 0.77 (0.31-1.88) for male gynecomastia ( 215 ).

Evidence to Decision Factors • Studies specifically comparing spironolactone vs other MRAs in medical PA treatment were few in number, small in size, and judged to be low quality. All used surrogate outcomes (eg, BP changes or serum potassium levels), typically ascer - tained after short treatment intervals.

MR-blocking potencies of various MRA agents were not routinely built into treatment protocols, and non - equivalent drug doses were sometimes compared.

• In order to proceed despite the evidence gaps, the GDP agreed to make the following 5 assumptions as part of the EtD process: ⚬ Each MRA, titrated appropriately, by blocking the MR, likely has an equal chance of eventually achieving the same degree of BP and potassium control in individ - uals with PA.

• Nonetheless, attempts at cost estimates in other cardiovas - cular conditions ( 216-218 ) consistently demonstrate markedly lower costs for spironolactone vs eplerenone; newer MRA drugs will likely have the highest costs.

Cost considerations or risk of unwanted anti-androgen effects may be secondary concerns and are likely highly significant when comparing spironolactone vs other MRAs. Shared decision making with individual patients allows for use of a non- spironolactone MRA in PA treatment where desired.
