Abstract
The clinical characteristics and outcomes in patients with clinical aldosterone-producing adenomas harboring KCNJ5 mutations with or without subclinical hypercortisolism remain unclear. This prospective study is aimed at determining factors associated with subclinical hypercortisolism in patients with clinical aldosterone-producing adenomas. Totally, 82 patients were recruited from November 2016 to March 2018 and underwent unilateral laparoscopic adrenalectomy with at least a 12-month follow-up postoperatively. Standard subclinical hypercortisolism (defined as cortisol >1.8 μg/dL after 1 mg dexamethasone suppression test [DST]) was detected in 22 (26.8%) of the 82 patients. Intriguingly, a generalized additive model identified the clinical aldosterone-producing adenoma patients with 1 mg DST>1.5 μg/dL had significantly larger tumors (P=0.02) than those with 1 mg DST<1.5 μg/dL. Multivariable logistic regression showed that the presence of KCNJ5 mutations (odds ratio, 0.22, P=0.010) and body mass index (odds ratio, 0.87, P=0.046) were negatively associated with 1 mg DST>1.5 μg/dL, whereas tumor size was positively associated with it (odds ratio, 2.85, P=0.014). Immunohistochemistry revealed a higher degree of immunoreactivity for CYP11B1 in adenomas with wild-type KCNJ5 (P=0.018), whereas CYP11B2 was more commonly detected in adenomas with KCNJ5 mutation (P=0.007). Patients with wild-type KCNJ5 and 1 mg DST>1.5 μg/dL exhibited the lowest complete clinical success rate (36.8%) after adrenalectomy. In conclusion, subclinical hypercortisolism is common in clinical aldosterone-producing adenoma patients without KCNJ5 mutation or with a relatively larger adrenal tumor. The presence of serum cortisol levels >1.5 μg/dL after 1 mg DST may be linked to a lower clinical complete success rate.

Histopathological and genetic characterization of aldosterone-producing adenomas with concurrent subclinical cortisol hypersecretion: a case series. Endocrine 2017; 58:503-512.

Abstract
PURPOSE Aldosterone-producing adenomas with concurrent subclinical cortisol hypersecretion are reported in an increasing number of patients. Five aldosterone-producing adenomas from patients with primary aldosteronism and subclinical hypercortisolism were examined. THE AIMS OF OUR STUDY WERE (1) to analyze pathological features and immunohistochemical expression of CYP11B1 (11β-hydroxylase) and CYP11B2 (aldosterone synthase) in these tumors; (2) to investigate somatic mutations involved in adrenal steroid hypersecretion and/or tumor growth. METHODS Archival micro-dissected paraffin-embedded slides from tumor specimens were used for histological and molecular studies. Immunohistochemistry was performed using monoclonal anti-CYP11B1 and anti-CYP11B2 antibodies. Cellular composition was determined by examining for known features of zona fasciculata and zona glomerulosa, and immunoreactivity for CYP11B1 and CYP11B2 by McCarty H-score. Spot regions for mutations in KCNJ5, ATP1A1, ATP2B3, CACNA1D, PRKACA, and CTNNB1 gene sequences were evaluated. RESULTS Four APAs showed a predominant (≥50%) zona fasciculata-like cell pattern: one tumor had CYP11B1 H-score = 150, no detectable CYP11B2 expression, and harbored a PRKACA p.Leu206Arg mutation (that we have reported previously elsewhere), one had no CYP11B1 expression, CYP11B2 H-score = 40, and no mutations; the remaining two adenomas had high CYP11B1 H-score (160 and 240, respectively) and low CYP11B2 H-score (30 and 15, respectively), with the latter harboring a CTNNB1 p.Ser45Phe activating mutation. One of five aldosterone-producing adenomas had a predominant zona glomerulosa-like pattern, CYP11B1 H-score = 15, CYP11B2 H-score = 180, and no mutations. CONCLUSIONS The majority of aldosterone-producing adenomas with concurrent subclinical cortisol hypersecretion were composed mainly of zona fasciculata-like cells, while CYP11B1 and CYP11B2 immunostaining demonstrated clear heterogeneity. In a subset of cases, different somatic mutations may be involved in hormone excess and tumor formation.

Aldosterone-Producing Adenomas. Hypertension 2017; 70:129-136.

Abstract
Mutations in
KCNJ5
,
ATP1A1
,
ATP2B3
,
CACNA1D
, and
CTNNB1
are thought to cause the excessive autonomous aldosterone secretion of aldosterone-producing adenomas (APAs). The histopathology of
KCNJ5
mutant APAs, the most common and largest, has been thoroughly investigated and shown to have a zona fasciculata–like composition. This study aims to characterize the histopathologic spectrum of the other genotypes and document the proliferation rate of the different sized APAs. Adrenals from 39 primary aldosteronism patients were immunohistochemically stained for CYP11B2 to confirm diagnosis of an APA. Twenty-eight adenomas had sufficient material for further analysis and were target sequenced at hot spots in the 5 causal genes. Ten adenomas had a
KCNJ5
mutation (35.7%), 7 adenomas had an
ATP1A1
mutation (25%), and 4 adenomas had a
CACNA1D
mutation (14.3%). One novel mutation in exon 28 of
CACNA1D
(V1153G) was identified. The mutation caused a hyperpolarizing shift of the voltage-dependent activation and inactivation and slowed the channel’s inactivation kinetics. Immunohistochemical stainings of CYP17A1 as a zona fasciculata cell marker and Ki67 as a proliferation marker were used.
KCNJ5
mutant adenomas showed a strong expression of CYP17A1, whereas
ATP1A1
/
CACNA1D
mutant adenomas had a predominantly negative expression (
P
value =1.20×10
−4
).
ATP1A1
/
CACNA1D
mutant adenomas had twice the nuclei with intense staining of Ki67 than
KCNJ5
mutant adenomas (0.7% [0.5%–1.9%] versus 0.4% [0.3%–0.7%];
P
value =0.04). Further, 3 adenomas with either an
ATP1A1
mutation or a
CACNA1D
mutation had >30% nuclei with moderate Ki67 staining. In summary, similar to
KCNJ5
mutant APAs,
ATP1A1
and
CACNA1D
mutant adenomas have a seemingly specific histopathologic phenotype.
