Growth Horm IGF Res 2023; 71:101545. [PMID: 37295337 DOI: 10.1016/j.ghir.2023.101545] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 05/23/2023] [Accepted: 05/29/2023] [Indexed: 06/12/2023]
Abstract
OBJECTIVE The growth hormone (GH)-releasing peptide-2 (GHRP-2) test is relatively safe among endocrine stimulation tests for the elderly. We investigated whether anterior pituitary function in elderly patients could be assessed on the basis of GH response to the GHRP-2 test. DESIGN Sixty-five elderly patients aged 65 years and older with non-functioning pituitary neuroendocrine tumor (PitNET) who underwent pituitary surgery and preoperative endocrine stimulation tests were classified into the "GH normal group" and "GH deficiency group" based on GH response to the GHRP-2 test. The baseline characteristics and anterior pituitary function were compared between the groups. RESULTS Thirty-two patients were assigned to the GH normal group and 33 to the GH deficiency group. The cortisol and adrenocorticotropic hormone (ACTH) results in the corticotropin-releasing hormone test were significantly higher in the GH normal group than in the GH deficiency group (p < 0.001). The relationship between the cortisol and ACTH results and the GH response revealed significant correlations (p < 0.001). In addition, receiver operating characteristic curve analysis identified that the optimal cut-off point for a peak GH level in the correlation between adrenocortical function and GH response to the GHRP-2 test was 8.08 ng/mL (specificity 0.868, sensitivity 0.852). CONCLUSION The present study indicated that adrenocortical function was significantly correlated with GH response to the GHRP-2 test in elderly patients before pituitary surgery. For elderly patients with non-functioning PitNET, GH response to the GHRP-2 test may support in diagnosing adrenocortical insufficiency.

Abstract
This review aims to provide an overview of metabolic and endocrine challenges in the setting of intensive care medicine. These are a group of heterogeneous clinical conditions with a high degree of overlap, as well as nonspecific signs and symptoms. Several diseases involve multiple organ systems, potentially causing catastrophic dysfunction and death. In the majority of cases, endocrine challenges accompany other organ failures or manifest as a complication of prolonged intensive care unit stay and malnutrition. However, when endocrine disorders present as an isolated syndrome, they are a rare and extreme manifestation. As they are uncommon, these can typically challenge both with diagnosis and management. Acute exacerbations may be elicited by triggers such as infections, trauma, surgery, and hemorrhage. In this complex scenario, early diagnosis and prompt treatment require knowledge of the specific endocrine syndrome. Here, we review diabetic coma, hyponatremia, hypercalcemia, thyroid emergencies, pituitary insufficiency, adrenal crisis, and vitamin D deficiency, highlighting diagnostic tools and tricks, and management pathways through defining common clinical presentations.

Abstract
BACKGROUND Pituitary apoplexy is an acute clinical syndrome caused by infarction and/or hemorrhage of pituitary adenoma, which typically presents with severe headache, visual deterioration, and endocrine abnormalities. However, temporal lobe seizure (and temporal lobe epilepsy) has not been viewed as a symptom of pituitary apoplexy in the literature. CASE DESCRIPTION To elucidate further such a rare complication of temporal lobe seizure, we describe here the rare clinical manifestations of a 55-year-old previously healthy man with pituitary apoplexy harboring headache, combined palsies involving cranial nerves III to VI, endocrinologic disturbances, and temporal lobe seizure. In addition, we discuss the temporal lobe seizure (and temporal lobe epilepsy) associated with pituitary adenoma based on the literature. CONCLUSIONS Although further accumulation of clinical data is needed, we would like to emphasize the importance of recognition of temporal lobe seizure caused by pituitary apoplexy, and to suggest that early surgery could be considered as an option in patients displaying such a rare complication.

Abstract
The insulin tolerance test (ITT) is the gold standard for diagnosing adrenal insufficiency (AI) after pituitary surgery. The ITT is unpleasant for patients, requires close medical supervision and is contraindicated in several comorbidities. The aim of this study was to analyze whether tumor size, remission rate, preoperative, and early postoperative baseline hormone concentrations could serve as predictors of AI in order to increase the diagnostic accuracy of morning serum cortisol. This prospective study enrolled 70 consecutive patients with newly diagnosed pituitary adenomas. Thirty-seven patients had nonfunctioning pituitary adenomas (NPA), 28 had prolactinomas and 5 had somatotropinomas. Thyroxin (T4), thyrotropin (TSH), prolactin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and insulin-like growth factor 1 (IGF-I) were measured preoperatively and on the sixth postoperative day. Serum morning cortisol was measured on the third postoperative day (CORT3) as well as the sixth postoperative day (CORT6). Tumor mass was measured preoperatively and remission was assessed 3 months after surgery. An ITT was performed 3 to 6 months postoperatively. Remission was achieved in 48% of patients and AI occurred in 51%. Remission rates and tumor type were not associated with AI. CORT3 had the best predictive value for AI (area under the curve (AUC) 0.868, sensitivity 82.4%, specificity 83.3%). Tumor size, preoperative T4, postoperative T4, and TSH were also associated with AI in a multivariate regression model. A combination of all preoperative and postoperative variables (excluding serum cortisol) had a sensitivity of 75.0% and specificity of 77.8%. The predictive power of CORT3 substantially improved by adding those variables into the model (AUC 0.921, sensitivity 94.1%, specificity 78.3%, PPV 81.9%, NPV of 92.7%). In a subgroup analysis that included only female patients with NPA, LH had exactly the same predictive value as CORT3. The addition of baseline LH to CORT3, increased sensitivity to 100.0%, specificity to 88.9%, PPV to 90.4%, and NPV to 100.0%. Besides CORT3, tumor size, thyroid hormones, and gonadotropins can serve as predictors of AI. LH in postmenopausal female patients with NPA has similar diagnostic accuracy as CORT3. Further studies are needed in order to validate the scoring system proposed by this study.

Abstract
Pituitary apoplexy, a rare clinical syndrome secondary to abrupt hemorrhage or infarction, complicates 2%-12% of pituitary adenomas, especially nonfunctioning tumors. Headache of sudden and severe onset is the main symptom, sometimes associated with visual disturbances or ocular palsy. Signs of meningeal irritation or altered consciousness may complicate the diagnosis. Precipitating factors (increase in intracranial pressure, arterial hypertension, major surgery, anticoagulant therapy or dynamic testing, etc) may be identified. Corticotropic deficiency with adrenal insufficiency may be life threatening if left untreated. Computed tomography or magnetic resonance imaging confirms the diagnosis by revealing a pituitary tumor with hemorrhagic and/or necrotic components. Formerly considered a neurosurgical emergency, pituitary apoplexy always used to be treated surgically. Nowadays, conservative management is increasingly used in selected patients (those without important visual acuity or field defects and with normal consciousness), because successive publications give converging evidence that a wait-and-see approach may also provide excellent outcomes in terms of oculomotor palsy, pituitary function and subsequent tumor growth. However, it must be kept in mind that studies comparing surgical approach and conservative management were retrospective and not controlled.

Abstract
Pituitary tumour apoplexy (PA) is a rare clinical syndrome that occurs as a result of acute haemorrhage and/or infarction within a frequently undiagnosed pituitary tumour. The sudden enlargement of the pituitary mass undergoing PA is responsible for a wide range of acute symptoms/signs (severe headache, visual loss, diplopia, hypopituitarism, impaired consciousness) which, together with the radiological evidence of a pituitary lesion, establish the diagnosis. The optimal care of PA requires involvement of a multidisciplinary team including endocrinologist, neurosurgeon, neuroophthalmologist and the management strategy that depends on the clinical manifestations, as well as the presence of co-morbidities. Prompt surgical decompression is initially indicated in cases with severe or progressive impairment of the visual acuity or the visual fields or with altered mental state and leads to visual and neurological recovery in most of the patients. The patients with mild, stable clinical picture (including those with isolated ocular palsies) can be managed conservatively (support of fluid and electrolyte balance and stress doses of steroids in most cases) with favourable visual and neurological outcome. Frequent reassessment is mandatory because the clinical course can be unpredictable; if progression of symptoms occurs, later elective surgery is indicated and is beneficial, especially in terms of visual outcome. The endocrinological outcome is less favourable, irrespective of the treatment option, with many patients remaining on long-term replacement therapy. Despite the above guidelines, clear proof of optimal outcomes in the form of randomised controlled trials is lacking. Regrowth of the pituitary tumour years after a PA episode is possible and patients require long-term surveillance.

Abstract
We review the etiology, investigations, management and outcomes of pituitary tumor apoplexy. Pituitary tumor apoplexy is a clinical syndrome which typically includes the acute onset of headache and/or visual disturbance, cranial nerve palsy and partial or complete endocrine dysfunction. It is associated with either infarction or hemorrhage of a pre-existing pituitary adenoma and is associated with significant morbidity and potential fatality. Not all patients will present with classic signs and symptoms, therefore it is pertinent to appreciate the clinical spectrum in which this condition can present.

Abstract
Pituitary apoplexy is a rare clinical syndrome attributable to hemorrhage or hemorrhagic infarction of pituitary tumors or pituitary glands. The features of pituitary apoplexy associated with the endocrine stimulation test remain to be elucidated and the importance of surgical treatment has not been discussed enough. We report two rare patients who were treated successfully by endoscopic endonasal transsphenoidal surgery within several hours after onset of pituitary apoplexy associated with the endocrine stimulation test. Their postoperative course was uneventful. We reviewed earlier reports on this clinical entity, document its features especially as related to the endocrine stimulation test, discuss the significance of immediate surgical treatment, and present our treatment outcomes. Performing only conservative treatment is not recommended. We suggest that the necessity of endocrine stimulation test should be assessed on a case-by-case basis and in patients subjected to the test, and neurosurgical support should be sought.

Abstract
AIM Our objective was to report a single-center experience of the management of pituitary tumor apoplexy. PATIENTS AND METHODS We retrospectively analyzed a series of 44 patients hospitalized for pituitary apoplexy between January 1996 and March 2008 at the Timone Hospital, Marseille, France. RESULTS Most frequent presenting symptoms were headaches (93%), visual impairment (85%) and vomiting (59%). Hypopituitarism was present at diagnosis in 88% of patients, with a high incidence of corticotroph deficiency (70%). A risk factor was found in 52% of patients, mostly hypertension. Apoplexy occurred in a previously undiagnosed pituitary adenoma in 32/44 cases (73%). The apoplectic event concerned 12 secreting, 27 non-functioning, 4 uncharacterized adenomas and one Rathke's pouch cyst. Nineteen patients underwent surgery within the first month, and one patient had conventional radiotherapy. Twenty-four patients, who had no ophthalmic or neurological signs, were conservatively treated in first intention; among them, 6 received high dose corticosteroids. After a median follow-up of 21 months, there was no significant difference in terms of endocrine or visual recovery between the operated and the conservatively treated groups, nor between patients treated with corticosteroids or not. Panhypopituitarism was observed in 52% of patients, but partial or complete visual recovery was present in the majority of patients (91%), whatever the therapeutic approach. CONCLUSION The outcome of patients treated with or without surgery for pituitary apoplexy without severe neuro-ophthalmic deficits seems to be identical, pleading for a conservative management of pituitary apoplexy in the absence of visual emergency.

Abstract
Classical pituitary apoplexy is a medical emergency and rapid replacement with hydrocortisone maybe life saving. It is a clinical syndrome characterized by the sudden onset of headache, vomiting, visual impairment and decreased consciousness caused by haemorrhage and/or infarction of the pituitary gland. It is associated with the sudden onset of headache accompanied or not by neurological symptoms involving the second, third, fourth and sixth cranial nerves. If diagnosed patients should be referred to a multidisciplinary team comprising, amongst others, a neurosurgeon and an endocrinologist. Apart from patients with worsening neurological symptoms in whom surgery is indicated, it is unclear currently for the majority of patients whether conservative or surgical management carries the best outcome. Post apoplexy, there needs to be careful monitoring for recurrence of tumour growth. It is suggested that further trials be carried out into the management of pituitary apoplexy to optimize treatment.

Abstract
Non-functioning pituitary tumours are mostly of gonadotroph cell origin and are devoid of humoral hypersecretory syndromes. They are usually large at the time of diagnosis, commonly presenting with headaches, visual field defects and hypopituitarism. Trans-sphenoidal surgery remains the treatment of choice for rapid decompression of neighbouring structures, often bringing to normalisation or improvement of visual and pituitary function. The management of patients with postoperative residual tumours is still a matter of debate and may include observation alone, the use of dopamine agonists or radiation therapy. There are no controlled or comparative studies of the available therapeutic options; therefore, recommendations are not evidence based. Patients need long-term follow-up for the detection and treatment of hypopituitarism, visual dysfunction and tumour growth that may develop over time.

Abstract
Evaluation of pituitary function is essential before pituitary surgery. In hyperprolactinaemic patients with a pituitary macrolesion, tumoral secretion of prolactin must be distinguished from 'disconnection' hyperprolactinaemia; serum prolactin >200 mcg/l is virtually diagnostic of a macroprolactinoma whereas levels <80 mcg/l usually indicate 'disconnection'. The prolactin 'hook effect' should be excluded. A minimum set of pre-operative endocrine tests should include serum electrolytes, cortisol (at 08.00-09.00 h), free-T4, TSH, prolactin, oestradiol/testosterone, LH, FSH and IGF-1. Some clinicians will choose to perform pre-operative Synacthen or insulin tolerance testing to further define ACTH reserve. If basal cortisol, Synacthen or insulin tolerance test results are abnormal, steroid supplementation is indicated for at least the first 48 h after surgery. If pre-operative basal cortisol is <100 nmol/l, replacement steroids should be continued until the time of post-operative pituitary function testing (6-8 weeks after surgery). In patients with pre-operative basal cortisol >450 nmol/l, peri-operative glucocorticoid replacement is unnecessary and further cortisol levels should be checked a few days after surgery. Most clinicians defer detailed evaluation of growth hormone reserve until after surgery. Diabetes insipidus is rarely a problem before surgery in patients with pituitary adenomas but may occur post-operatively. Close co-operation between anesthetic, endocrine and surgical teams is strongly recommended.
