Craniopharyngioma in Adults

Craniopharyngiomas are slow growing benign tumors of the sellar and parasellar region with an overall incidence rate of approximately 1.3 per million. During adulthood there is a peak incidence between 40 and 44 years. There are two histopathological types, the adamantinomatous and the papillary type. The later type occurs almost exclusively in adult patients. The presenting symptoms develop over years and display a wide spectrum comprising visual, endocrine, hypothalamic, neurological, and neuropsychological manifestations. Currently, the main treatment option consists in surgical excision followed by radiation therapy in case of residual tumor. Whether gross total or partial resection should be preferred has to be balanced on an individual basis considering the extent of the tumor (e.g., hypothalamic invasion). Although the overall long-term survival is good it is often associated with substantial morbidity. Preexisting disorders are often permanent or even exacerbated by treatment. Endocrine disturbances need careful replacement and metabolic sequelae should be effectively treated. Regular follow-up by a multidisciplinary team is a prerequisite for optimal outcome of these patients

Personality traits and physical complaints in patients with acromegaly : a cross sectional multi-center study with analysis of influencing factors

Objective: Acromegalic patients display a distinct neuropsychological profile and suffer from chronic physical complaints. We aimed to investigate in more detail these aspects in acromegalic patients, dependent on influencing factors like disease activity, age, sex, chronic medication, surgery, pituitary radiation, pituitary insufficiency and comorbidities. Design: Cross sectional, multicentric. Methods: 129 patients (M/W 65/64, 58.3±12.7 ys., 53/76 with active/controlled disease). Acromegalic patients completed the following inventories: NEO-FFI, IIP-D, and the Giessen Complaints List (GBB-24), after written informed consent. Age, sex, IGF-1 concentrations, comorbidities, treatment modalities and pituitary insufficiency were documented. Results: Acromegalic patients or specific patient-subgroups were more agreeable, neurotic, exploitable/permissive, introverted/socially avoidant, non-assertive/insecure, nurturant and less open to experience, cold/denying, domineering, compared to normal values from the healthy population (controls). Multivariable analysis demonstrated that these overall results were due to the specific patient subgroups as patients on chronic medication, with arthrosis and pituitary insufficiency. Disease activity was only associated with the trait nurturant. Higher scores for introversion were associated with arthrosis. Lower domineering was independent of any disease- or treatment related variable or comorbidity. The GBB inventory showed overall higher scores in patients, with higher scores for exhaustion and general complaints being associated with pituitary insufficiency, coronary heart disease and history of malignancy in the multivariable analysis. Joint complaints were independent of any disease- or treatment- related variable. Conclusions: We define new aspects of a distinct neuropsychological profile in patients with acromegaly, which are largely independent of disease activity. Chronic physical complaints are more pronounced in patients than in controls, with exhaustion and general complaints showing no association with disease activity

Significant benefits of AIP testing and clinical screening in familial isolated and young-onset pituitary tumors

Context Germline mutations in the aryl hydrocarbon receptor-interacting protein (AIP) gene are responsible for a subset of familial isolated pituitary adenoma (FIPA) cases and sporadic pituitary neuroendocrine tumors (PitNETs). Objective To compare prospectively diagnosed AIP mutation-positive (AIPmut) PitNET patients with clinically presenting patients and to compare the clinical characteristics of AIPmut and AIPneg PitNET patients. Design 12-year prospective, observational study. Participants & Setting We studied probands and family members of FIPA kindreds and sporadic patients with disease onset ≤18 years or macroadenomas with onset ≤30 years (n = 1477). This was a collaborative study conducted at referral centers for pituitary diseases. Interventions & Outcome AIP testing and clinical screening for pituitary disease. Comparison of characteristics of prospectively diagnosed (n = 22) vs clinically presenting AIPmut PitNET patients (n = 145), and AIPmut (n = 167) vs AIPneg PitNET patients (n = 1310). Results Prospectively diagnosed AIPmut PitNET patients had smaller lesions with less suprasellar extension or cavernous sinus invasion and required fewer treatments with fewer operations and no radiotherapy compared with clinically presenting cases; there were fewer cases with active disease and hypopituitarism at last follow-up. When comparing AIPmut and AIPneg cases, AIPmut patients were more often males, younger, more often had GH excess, pituitary apoplexy, suprasellar extension, and more patients required multimodal therapy, including radiotherapy. AIPmut patients (n = 136) with GH excess were taller than AIPneg counterparts (n = 650). Conclusions Prospectively diagnosed AIPmut patients show better outcomes than clinically presenting cases, demonstrating the benefits of genetic and clinical screening. AIP-related pituitary disease has a wide spectrum ranging from aggressively growing lesions to stable or indolent disease course

Efficacy and safety of once-monthly pasireotide in Cushing's disease: A 12 month clinical trial

© 2017 Elsevier Ltd. Background: Cushing's disease is a rare debilitating endocrine disorder for which few prospective interventional studies have been done. We report results of the first phase 3 trial assessing long-acting intramuscular pasireotide in patients with Cushing's disease. Methods: In this phase 3 clinical trial we recruited patients aged 18 years or older with persistent, recurrent, or de-novo (non-surgical candidates) Cushing's disease who had a mean urinary free cortisol (mUFC) concentration (from three 24 h samples) of 1·5-5·0 times the upper limit of normal (ULN), a normal or greater than normal morning plasma adrenocorticotropic hormone concentration, and a pituitary source of Cushing's syndrome, from 57 sites across 19 countries. Exclusion criteria included previous pasireotide treatment, mitotane therapy within 6 months, and pituitary irradiation within 10 years. We randomly allocated patients 1:1 (block size of four) using an interactive-response-technology system to intramuscular pasireotide 10 mg or 30 mg every 4 weeks for 12 months (in the core phase). We stratified randomisation by screening mUFC concentration (1·5 to < 2·0 × ULN and 2·0-5·0 × ULN). The dose could be uptitrated (from 10 mg to 30 mg or from 30 mg to 40 mg) at month 4 if the mUFC concentration was greater than 1·5 × ULN, and at month 7, month 9, or month 12 if the mUFC concentration was greater than 1·0 × ULN. Investigators, patients, site personnel, and those assessing outcomes were masked to dose group allocation. The primary endpoint was the proportion of patients in each group with an mUFC concentration of less than or equal to the ULN at month 7. Efficacy analyses were based on intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01374906. Findings: Between Dec 28, 2011, and Dec 9, 2014, we randomly allocated 150 patients to receive pasireotide 10 mg (74 [49%] patients) or 30 mg (76 [51%] patients). The primary efficacy endpoint was met by 31 (41·9% [95% CI 30·5-53·9]) of 74 patients in the 10 mg group and 31 (40·8% [29·7-52·7] ) of 76 in the 30 mg group. The most common adverse events were hyperglycaemia (36 [49%] in the 10 mg group and 36 [47%] in the 30 mg group), diarrhoea (26 [35%] and 33 [43%] ), cholelithiasis (15 [20%] and 34 [45%] ), diabetes mellitus (14 [19%] and 18 [24%] ), and nausea (15 [20%] and 16 [21%] ). Serious adverse events suspected to be study drug related were reported in eight (11%) patients in the 10 mg group and four (5%) in the 30 mg group. Two (3%) patients in the 30 mg group died during the study (pulmonary artery thrombosis and cardiorespiratory failure); neither death was judged to be related to the study drug. Interpretation: Long-acting pasireotide normalised mUFC concentration in about 40% of patients with Cushing's disease at month 7 and had a similar safety profile to that of twice-daily subcutaneous pasireotide. Long-acting pasireotide is an efficacious treatment option for some patients with Cushing's disease who have persistent or recurrent disease after initial surgery or are not surgical candidates, and provides a convenient monthly administration schedule.

Adrenarche and Puberty in Children with Classic Congenital Adrenal Hyperplasia due to 21-Hydroxylase Deficiency

There have been only a few studies on adrenarche in girls with classic congenital adrenal hyperplasia (CAH) showing that dehydroepiandrosterone sulfate (DHEAS) levels did not rise at the physiological age of adrenarche. Objective: Longitudinal analysis of serum DHEAS levels and Tanner stages in CAH children. Design: We studied 98 CAH patients (52 females), aged between 1 month and 18.0 years. All patients had genetically proven classic CAH and received steroid substitution therapy. Results: Serum DHEAS levels did not differ between CAH children and healthy children from the age of 1 year until 5–6 years. Beginning at the age of 7–8 years, there was a continuous but blunted increase in DHEAS levels in CAH boys and girls compared to healthy children. There was no correlation of DHEAS levels with the genotype, glucocorticoid dosage, auxological data, or quality of metabolic control. Pubarche (PH2) as well as gonadarche (G2) and thelarche (B2) occurred significantly earlier in CAH boys and girls than in the reference group, but timing of menarche was normal. Conclusions: Pubarche and adrenarche are dissociated in classic CAH: earlier pubarche, gonadarche and thelarche, respectively, in both sexes contrast with the absence of typical adrenarche

Daily adjustment of glucocorticoids by patients with adrenal insufficiency

BACKGROUND Patients with adrenal insufficiency (AI) require lifelong glucocorticoid (GC) replacement. AI patients need to adjust GC dosage in response to stressful events and illness in order to prevent life-threatening adrenal crisis (AC). AIM To evaluate self-management of patients with AI. METHODS Four German centres, which are using patient's diary as part of their routine clinical practice, instructed AI patients to prospectively document any discomfort, intercurrent illness or stressful events as well as changes in GC therapy on a daily basis. Diaries of 80 patients (44 females, 52.9 ± 15.9 years, 34 primary AI) were collected and analysed. A symptom score sheet was used to evaluate severity of discomfort. RESULTS In total, 34 074 patient days (93.4 years) were recorded. 4622 days with discomfort were documented. On 35% of those days (n = 1621), patients increased their GC dose (4.8% of all days). Patients who recorded discomfort had a median of four episodes of discomfort, which lasted a median of 2 days. Women documented significantly more episodes of discomfort than men (P = 0.014). Low-to-median symptom scores resulted in GC increase by 50%-60%, whereas high symptom scores and/or fever resulted in doubling GC daily dose. However, dose increase was only 55% in situations indicating gastrointestinal (GI) infection. CONCLUSION Severe discomfort did not always result in dose increase, especially in GI infection. However, low symptom scores resulted in an inappropriate GC increase in some patients. This underscores an urgent need for improved training methods. Keeping daily records might be a useful tool for continued and individualized patient education
