A retrospective analysis of postoperative hypokalemia in pituitary adenomas after transsphenoidal surgery

Abstract.

Background

Pituitary adenoma is one of the most common intracranial neoplasms, and its primary treatment is endoscopic endonasal transsphenoidal tumorectomy. Postoperative hypokalemia in these patients is a common complication, and is associated with morbidity and mortality. This study aimed to analyze the etiopathology of postoperative hypokalemia in pituitary adenomas after endoscopic transsphenoidal surgery.

Methods and Materials

This retrospective study included 181 pituitary adenomas confirmed by histopathology. Unconditional logistic regression analysis was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Repeated measures ANOVA was used to analyze change in serum potassium levels at different time points.

Results

Multiple Logistic regression analysis revealed that only ACTH-pituitary adenoma (OR = 4.92, 95% CI [1.18–20.48], P = 0.029) had a significant association with postoperative hypokalemia. Moreover, the overall mean serum potassium concentration was significantly lower in the ACTH versus the non-ACTH group (3.34 mmol/L vs. 3.79 mmol/L, P = 0.001). Postoperative hypokalemia was predominantly found in patients with ACTH-pituitary adenoma (P = 0.033).

Conclusions

ACTH-pituitary adenomas may be an independent factor related postoperative hypokalemia in patients despite conventional potassium supplementation in the immediate postoperative period.

Basal Cortisol Elevated in Patients with ACTH-Staining Pituitary Macroadenoma

Preoperative identification of patients with silent adrenocorticotrophic hormone-secreting tumors could potentially change the approach to management. A new study aimed to determine whether a preoperative adrenocorticotrophic hormone stimulation test for evaluation of nonfunctional pituitary macroadenoma could aid in identifying adrenocorticotrophic hormone-staining pathology yielded large variability and did not allow clinical utility.

Thus, researchers concluded that larger, multicenter research is needed to determine whether this test can be useful.

“As ACTH stimulation tests are performed routinely when evaluating macroadenoma when there is no suspicion for a state of endogenous hypercortisolism, we sought to determine if the test could reliably identify these pathologies during the preoperative evaluation. We hypothesized that patients with subclinical Cushing’s disease or silent ACTH-secreting tumors would have a higher delta cortisol on the ACTH stimulation tests vs. other types of macroadenoma pathologies,” Kevin Pantalone, DO, ECNU, FACE, staff endocrinologist and director of clinical research in the department of endocrinology at Cleveland Clinic, told Endocrine Today.

Pantalone and colleagues performed a retrospective chart review of 148 patients with pituitary macroadenoma who underwent preoperative ACTH stimulation tests, with the goal of determining whether the test can aid in the identification of ACTH-staining pathology.

Overall, 9.5% of patients showed diffuse staining, 50.6% showed other-staining (diffuse staining for anterior pituitary hormones other than ACTH) and 39.9% showed no staining (no staining for any anterior pituitary hormones).

The researchers calculated delta total cortisol at 30 and 60 minutes from baseline and reviewed preoperative ACTH stimulation tests. Additionally, Pantalone and colleagues compared the basal and maximal delta cortisol between the ACTH-staining pituitary macroadenoma and the non-ACTH staining (n = 134), other staining (n = 75) and non-staining (n = 59) tumors.

According to data reported at the American Association of Clinical Endocrinologists Annual Scientific and Clinical Congress, the ACTH-staining group had higher mean basal cortisol levels compared with the non-ACTH-staining (P = .012), other staining (P = .018) and the non-staining (P = .012) tumors. The researchers found no significant differences in maximal delta cortisol between the groups.

“While we found basal cortisol levels were higher in patients with ACTH-staining pituitary microadenoma vs. non-ACTH-staining macroadenoma, the large variability in cortisol values did not allow for clinical utility,” Pantalone told Endocrine Today.

“Unfortunately, in the end, our study was limited by the number of cases with ACTH-staining pathology. Thus, we were unable to determine if the ACTH stimulation test could reliably assist clinicians in potentially identifying ACTH-staining pathology in the preoperative setting,” he said. “A multicenter study, affording a large number of ACTH-staining tumors, is needed. This may allow for us to determine if the ACTH-stimulation test can really be clinically useful in preoperatively identifying ACTH-staining pathology.” – by Amber Cox

Cushing’s appears to begin its cardiovascular effects during childhood

– Cushing’s disease may begin to exert its harmful cardiovascular effects quite early, a small pediatric study has found.

Children as young as 6 years old with the disorder already may show signs of cardiovascular remodeling, with stiffer aortas and higher aortic pulse-wave velocity than do age-matched controls, Hailey Blain and Maya Lodish, MD, said at the annual meeting of the Endocrine Society.

“The study, which included 10 patients, is small, but we continue to add new patients,” said Dr. Lodish, director of the pediatric endocrinology fellowship program at the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Ten more children are being added to the cohort now, and she and Ms. Blain, a former research fellow at NIH, intend to grow the group and follow patients longitudinally.

Cushing’s disease has long been linked with increased cardiovascular risk in adults, but the study by Dr. Lodish and Ms. Blain is one of the first to examine the link in children. Their findings suggest that early cardiovascular risk factor management should be a routine part of these patients’ care, Dr. Lodish said in an interview.

“It’s very important to make sure that there is recognition of the cardiovascular risk factors that go along with this disease. Elevated levels of cholesterol, hypertension, and other risk factors that are in these individuals should be ameliorated as soon as possible from an early age and, most importantly, physicians should be diagnosing and treating children early, once they are identified as having Cushing’s disease. And, given that we are not sure whether these changes are reversible, we need to make sure these children are followed very closely.”

Indeed, Dr. Lodish has reason to believe that the changes may be long lasting or even permanent.

“We are looking at these children longitudinally and have 3-year data on some patients already. We want to see if they return to normal pulse wave velocity after surgical cure, or whether this is permanent remodeling. There is an implication already that it may be in a subset of individuals,” she said, citing her own 2009 study on hypertension in pediatric Cushing’s patients. “We looked at blood pressure at presentation, after surgical cure, and 1 year later. A significant portion of the kids still had hypertension at 1 year. This leads us to wonder if they will continue to be at risk for cardiovascular morbidity as adults.”

Ms. Blaine, an undergraduate at Bowdoin College, Brunswick, Maine, worked on the study during a summer internship with Dr. Lodish and presented its results in a poster forum during meeting. She examined two indicators of cardiovascular remodeling – aortic pulse wave velocity and aortic distensibility – in 10 patients who were a mean of 13 years old. All of the children came to NIH for diagnosis and treatment of Cushing’s; as part of that, all underwent a cardiac MRI.

The patients had a mean 2.5-year history of Cushing’s disease Their mean midnight cortisol level was 18.8 mcg/dL and mean plasma adrenocorticotropic hormone level, 77.3 pg/mL. Five patients were taking antihypertensive medications. Low- and high-density lipoprotein levels were acceptable in all patients.

The cardiovascular measures were compared to an age-matched historical control group. In this comparison, patients had significantly higher pulse wave velocity compared with controls (mean 4 vs. 3.4 m/s). Pulse wave velocity positively correlated with both midnight plasma cortisol and 24-hour urinary free cortisol collections. In the three patients with long-term follow-up after surgical cure of Cushing’s, the pulse wave velocity did not improve, either at 6 months or 1 year after surgery. This finding echoes those of Dr. Lodish’s 2009 paper, suggesting that once cardiovascular remodeling sets in, the changes may be long lasting.

“The link between Cushing’s and cardiovascular remodeling is related to the other things that go along with the disease,” Dr. Lodish said. “The hypertension, the adiposity, and the high cholesterol all may contribute to arterial rigidity. It’s also thought to be due to an increase in connective tissue. The bioelastic function of the aorta may be affected by having Cushing’s.”

That connection also suggests that certain antihypertensives may be more beneficial to patients with Cushing’s disease, she added. “It might have an implication in what blood pressure drug you use. Angiotensin-converting enzyme inhibitors increase vascular distensibility and inhibit collagen formation and fibrosis. It is a pilot study and needs longitudinal follow up and additional patient accrual, however, finding signs of cardiovascular remodeling in young children with Cushing’s is intriguing and deserves further study.”

Neither Ms. Blain nor Dr. Lodish had any financial disclosures.
