RESUMO
BACKGROUND: Acromegaly (ACRO) is a chronic rare disease caused by a pathological increase in growth hormone (GH) secretion. In ACRO an increased prevalence of psychiatric disorders has been demonstrated, in particular depressive disorders, associated to a significant deterioration of the quality of life, independently from disease control. In addition, anger feelings, often detected in subjects affected by chronic disease, have not yet been investigated, in pituitary patients. Aim of the study was to evaluate in ACRO patients with a controlled disease, compared to patients suffering for non-functioning pituitary adenoma (NFPA) 1) prevalence of depressive and anxiety disorders, and 2) expression and control of anger feelings. The second purpose was to evaluate the correlation between psychiatric disorders, anger feelings and the "activity of disease," that is active ACRO that needs medical treatment versus cured ACRO. METHODS: This is a cross-sectional, observational study, which included 53 patients enrolled at the Neuroendocrinology Outpatient Clinic of "Città della Salute e della Scienza di Torino". Of the 53 enrolled patients (24 male and 29 female), 34 had ACRO, while 19 had NFPA, as control group. All subjects went through the following self-administered, validated psychological tools: SF-36 (Short-Form 36 Item); STAXI - 2; BDI-II (Beck Depression Inventory -II); STAI (State-Trait Anxiety Inventory). Only in ACRO group, patients completed PASQ (Patient-Assessed Acromegaly Symptom Questionnaire) and ACROQoL (Acromegaly Quality of Life Questionnaire) questionnaires. In addition 45 patients underwent the International Neuropsychiatric Short Interview to assess the presence of a psychiatric disorder. For each patient, anthropometric, clinical and biochemical information was collected. RESULTS: A higher frequency of psychiatric anxiety and mood disorders (not reported in the medical history) was observed in patients with controlled ACRO. In the SF-36 questionnaire, a lower score was found in the "emotional well-being" items in ACRO compared to NFPA, particularly in those with cured ACRO. Cured acromegalic patients had a worse score in "emotional well-being," "energy/fatigue" and "general health" items. Finally, subjects in ACRO group obtained a lower score in the ability to control anger and a higher score in the physical expression of it, demonstrating a tendency to more aggressive behaviors. CONCLUSIONS: This study showed that psychiatric illness is often hidden in patient suffering from ACRO, despite normal IGF-I levels. Recovery from the disease do not necessarily improve QoL scores, in fact in cured patients the quality of life can be even worse.
RESUMO
Intracranial tumors of different histologic types infrequently affect patients with pituitary adenomas and no history of head irradiation. The association with craniopharyngioma is extremely rare. Aims of this paper are: (1) to provide a critical literature review of typical features of pituitary adenoma presenting in association with craniopharyngioma; (2) to describe the first documented (clinically, biochemically, histologically, and radiologically) case of aggressive, suprasellar papillary craniopharyngioma presenting with amenorrhea, progressive reduction of visual field, and severe headache in a 38-year-old woman, a decade after surgical cure for microprolactinoma associated with empty sella, during which she had carried two pregnancies; and (3) to discuss common etiopathogenetic mechanisms, in relation to the management of these lesions. Systematic literature search for English literature focusing on the association of craniopharyngioma and pituitary adenoma was performed using PubMed database. Additional relevant articles from references lists were also included. Clinical, laboratory, and radiological examinations performed in our patient for the two brain lesions at diagnosis and follow up were collected. Literature search retrieved nine articles. Typically, craniopharyngioma were of adamantinomatous type, occurred simultaneously to pituitary adenoma, presented with headache and visual loss, and affected men. No case of clearly documented metachronous lesion affecting a woman after pregnancy had been described before. Although very rare and with uncertain etiopathogenesis, second tumors (i.e., craniopharyngioma) should be considered in patients with a history of pituitary adenoma, presenting with suggestive signs and symptoms, even after a long disease-free period, in order to provide proper and prompt treatment.
