    Abstract: Pheochromocytoma crisis results from the sudden release of large quantities of catecholamines and leads to progressive multiple organ dysfunction. Here we report a case of pheochromocytoma crisis with symptoms associated with acute coronary syndrome (ACS) and severe fluctuations in blood pressure (BP). A 43-year-old Japanese man with hypertension (240/120 mmHg) visited a general hospital for chest pain. Echocardiogram showed ST segment depression and blood test demonstrated elevated troponin T. However, emergent coronary angiography revealed normal findings. CT showed a large adrenal mass on the left side, which was suspected as the cause of chest pain and BP elevation. After the patient was transported to our hospital, his BP was found to oscillate between 70 and 240 mmHg, and level of consciousness was decreased. After hospitalization, he had a further decrease in consciousness, a rise in body temperature, and a gradual increase in the interval between the upper and lower systolic BP. His systolic BP varied between 30 mmHg and 300 mmHg at the intervals of 20-30 min. After a multimodality therapy, including α-blocker and high dose fluid replacement, the fluctuation in his BP was gradually decreased and got stabilized after approximately 24 h. Approximately 3 weeks later, he underwent left adrenalectomy. This case showed that pheochromocytoma with internal necrosis might be misdiagnosed as ACS. Furthermore, in cases with a large adrenal tumor and severe elevation or fluctuations of BP, pheochromocytoma should be suspected and treated with α-blockers and fluid replacements as soon as possible prior to surgery. Learning points: High catecholamine levels due to pheochromocytoma crisis might cause symptoms associated with acute coronary syndrome. Adrenal tumor with internal necrosis and the elevation or fluctuations of blood pressure should be suspected to be pheochromocytoma. If pheochromocytoma crisis is suspected, the specialist, such as an endocrinologist or a urologist, should intervene, and an α-blocker treatment with adequate fluid replacement therapy should be initiated as soon as possible. Pheochromocytoma multisystem crisis (PMC) is a fatal condition characterized by multiple organ failure, severe blood pressure variability, high fever, and encephalopathy. This is an extremely rare subtype of a very rare disease such as pheochromocytoma. However, because the fatality rate of PMC is high, clinicians should be aware of the symptoms that mark its onset.

    Abstract: ENDO 2020 Epigenetic regulation of 11beta-hydroxysteroid dehydrogenase 1 and 2 gene in salt-sensitive hypertensive rats [Objective]11Beta-hydroxysteroid dehydrogenase type1 (11-HSD1) is the modulator of glucocorticoid hormone and type2 (11-HSD2) is the modulator of mineralocorticoid hormone. We investigated the effect of high salt diet on the methylation of both enzyme gene in salt-sensitive hypertensive (SSH) rats [Methods] SSH rats were fed a high (7% NaCl) or normal (0.45%) salt chow for 4 weeks. Body weight, blood pressure, plasma and urinary aldosterone concentration and PRA were measured. DNA was extracted from kidneys and visceral fats. Bisulfite sequencing and Pyrosequencing were done for the analysis of methylation status of 11-HSD1 and 2 gene. [Results] High salt diet significantly decreased methylation ratio of 11-HSD1 gene in the visceral fats of SSH rats compared with controls (p & lt;0.05). The methylation ratio of 11-HSD2 gene in the kidney of SSH rats was not influenced by high salt diet. [Discussion and Conclusion]11-HSD1 overexpression in visceral fats in mice was reported to show SSH. We reported decreased 11-HSD2 activity in the artery in SSH rats. In this study high salt diet affected methylation status of 11-HSD1 in the adipose tissue but not 11-HSD2 gene in the kidney in SSH. Food intake such as salt may influence the epigenesis of 11-HSD and induce hypertension.

    Abstract: Salt intake is one of most important environmental factors responsible for triggering the onset of hypertension. Renin-angiotensin-aldosterone system (RAAS) plays a key role in adjusting sodium homeostasis and blood pressure. Recently, the potential role of the gut microbiome (GM) in altering the health of the host has drawn considerable attention. We investigated the impact of intestinal microflora and RAAS in hypertensive patients with low-salt or high-salt intake using an observational study. A total of 239 participants were enrolled and their GMs and clinical backgrounds examined, including the renin-angiotensin-aldosterone system and inflammatory cytokine levels. On the basis of enterotypes—determined by cluster analysis—and salt intake, the participants were classified into four groups, low salt/GM enterotype 1, low salt/GM enterotype 2, high salt/GM enterotype 1, and high salt/GM enterotype 2. The prevalence of hypertension was significantly lower in the low-salt intake (low salt/GM enterotype 1 = 47% vs low salt/GM enterotype 2 = 27%, p = 0.04) groups. No significant difference in the prevalence of hypertension was observed for the two GM enterotype groups with high-salt intake (GM enterotype 1 = 50%, GM enterotype 2 = 47%; p = 0.83). Plasma aldosterone concentration was significantly different among the four groups (p & lt; 0.01). Furthermore, the relative abundance of Blautia, Bifidobacterium, Escherichia-Shigella, Lachnoclostridium, and Clostridium sensu stricto was also significantly different among these enterotypes. This suggested in certain individuals (with specific gut bacteria composition) changing dietary habits—to low salt—would be ineffective for regulating hypertension through RAAS. Our findings provide a new strategy for controlling blood pressure and preventing the development of hypertension through restoring GM homeostasis.

    Abstract: Artery fenestration is a congenital vascular malformation, often of the intracranial arteries, that causes an aneurysm. However, there have been no reports of artery fenestration causing renal aneurysm. We present the case of a 58-year-old man who developed renin-dependent hypertension. He was aware of heaviness of the head, and his blood pressure was 196/134 mm Hg on 5 mg of amlodipine. Laboratory tests showed hypokalemia, hyperreninemia, and hyperaldosteronemia. An enhanced 3-dimensional computed tomography scan showed a 19-mm renal aneurysm in a branch of the left renal artery, and renal arteriography showed a fenestration in the aneurysm-forming branch. Coil embolization was performed on the central side of the artery forming the aneurysm and fenestration, after which blood pressure, serum potassium, and plasma renin levels improved. The patient in the present case had renin-dependent hypertension as a result of decreased renal blood flow caused by the renal aneurysm and fenestration, which is considered an extremely rare etiology of hypertension.

    Abstract: Renovascular hypertension (RVHT) is an important and potentially treatable form of resistant hypertension. Hypercortisolemia could also cause hypertension and diabetes mellitus. We experienced a case wherein adrenalectomy markedly improved blood pressure and plasma glucose levels in a patient with RVHT and subclinical Cushing’s syndrome. A 62-year-old Japanese man had been treated for hypertension and diabetes mellitus for 10 years. He was hospitalized because of disturbance in consciousness. His blood pressure (BP) was 236/118 mmHg; pulse rate, 132 beats/min; and plasma glucose level, 712 mg/dl. Abdominal computed tomography scanning revealed the presence of bilateral adrenal masses and left atrophic kidney. Abdominal magnetic resonance angiography demonstrated marked stenosis of the left main renal artery. The patient was subsequently diagnosed with atherosclerotic RVHT with left renal artery stenosis. Bilateral adrenal masses were immunohistologically identified as potential sites for cortisol overproduction. Therefore, laparoscopic left nephrectomy and adrenalectomy were simultaneously performed resulting in improved BP and glucose levels. Pathological studies revealed the presence of multiple cortisol-producing adrenal nodules and aldosterone-producing cell clusters in the adjacent left adrenal cortex. In the present case, activated renin-angiotensin-aldosterone system and cortisol overproduction resulted in severe hypertension, which was managed with simultaneous unilateral nephrectomy and adrenalectomy.

    Abstract: Background: The primary aldosteronism (PA) subtype is usually confirmed by computed tomography (CT) and adrenal venous sampling (AVS). However, the subtype diagnosis by AVS is not necessarily consistent with the subtype diagnosis by CT. Patients with PA who show normal-appearing adrenals on CT but unilateral disease on AVS (CT-negative and AVS-unilateral group) are often found. However, few studies have focused on them, despite a discrepancy between CT and AVS subtype diagnosis. Objective: The aim of this study was to evaluate the clinical features of CT-negative and AVS-unilateral group and assess whether they obtain benefits from surgery. Methods: We retrospectively analyzed 362 consecutive patients with PA who underwent both CT and adrenocorticotropic hormone (ACTH)-unstimulated AVS at Kanazawa University Hospital. First, the patients were divided into normal-appearing adrenals, bilateral adrenal nodules, or unilateral adrenal nodules based on CT findings. Second, they were classified as having unilateral or bilateral disease based on ACTH-unstimulated AVS. The criterion for successful selective catheterization was selectivity index & gt;2 and unilateral aldosterone overproduction was confirmed by lateralized index ≥2. Among the group with normal appearing-adrenals on CT, we examined preoperative clinical characteristics between those with unilateral disease on AVS and those with bilateral disease on AVS. In addition, we compared surgical outcomes of CT-negative and AVS-unilateral group with those of CT-unilateral and AVS-ipsilateral group (patients with unilateral lesions on CT and ipsilateral disease on AVS). The Surgical outcomes for unilateral PA were evaluated according to the criteria of the Primary Aldosteronism Surgical Outcome study. Results: The success rate of AVS in patients with normal-appearing adrenals on CT was 88% (167/190). Furthermore, the discordance rate between CT and AVS in patients with normal-appearing adrenals on CT was 36% (60/167). There were no significant differences in preoperative clinical characteristics between the CT-negative and AVS-unilateral group (n=60) and the CT-negative and AVS-bilateral group (n=107). After surgery, the CT-negative and AVS-unilateral group (n=14) had a lower complete biochemical success rate than the CT-unilateral and AVS-ipsilateral group (n=30) (43% vs. 80%, p=0.02), but clinical and biochemical benefits (the complete and partial success combined) were not significantly different between them (71% vs. 93% (p=0.07) and 71% vs. 90% (p=0.13), respectively). Conclusion: The clinical features of CT-negative and AVS-unilateral group were significantly similar to those of CT-negative and AVS-bilateral group. They benefited from surgery, and AVS should be performed for patients who pursue surgical management when the CT findings suggest normal-appearing adrenals.

    Abstract: Renovascular hypertension (RVHT) is an important and potentially treatable form of resistant hypertension. Hypercortisolemia could also cause hypertension and diabetes mellitus. We experienced a case wherein adrenalectomy markedly improved blood pressure and plasma glucose levels in a patient with RVHT and low-level autonomous cortisol secretion. A 62-year-old Japanese man had been treated for hypertension and diabetes mellitus for 10 years. He was hospitalized because of a disturbance in consciousness. His blood pressure (BP) was 236/118 mmHg, pulse rate was 132 beats/min, and plasma glucose level was 712 mg/dL. Abdominal CT scanning revealed the presence of bilateral adrenal masses and left atrophic kidney. Abdominal magnetic resonance angiography demonstrated marked stenosis of the left main renal artery. The patient was subsequently diagnosed with atherosclerotic RVHT with left renal artery stenosis. His left adrenal lobular mass was over 40 mm and it was clinically suspected the potential for cortisol overproduction. Therefore, laparoscopic left nephrectomy and adrenalectomy were simultaneously performed, resulting in improved BP and glucose levels. Pathological studies revealed the presence of multiple cortisol-producing adrenal nodules and aldosterone-producing cell clusters in the adjacent left adrenal cortex. In the present case, the activated renin-angiotensin-aldosterone system and cortisol overproduction resulted in severe hypertension, which was managed with simultaneous unilateral nephrectomy and adrenalectomy. Learning points: Concomitant activation of the renin-angiotensin-aldosterone system and cortisol overproduction may contribute to the development of severe hypertension and lead to lethal cardiovascular complications. Treatment with simultaneous unilateral nephrectomy and adrenalectomy markedly improves BP and blood glucose levels. CYP11B2 immunohistochemistry staining revealed the existence of aldosterone-producing cell clusters (APCCs) in the adjacent non-nodular adrenal gland, suggesting that APCCs may contribute to aldosterone overproduction in patients with RVHT.
