    The effect of cabergoline on secretion of SICAM 1 and cytokines in human pituitary adenoma cell culture

    Acta Endo (Buc) 2010 6(4): 443-454 doi: 10.4183/aeb.2010.443

    Our aim was to explore the interactions of intercellular adhesion molecule (sICAM-1), TNF-&#945; (tumor necrosis factor-&#945;), interleukin-1&#945; (IL-1&#945;) and interleukin-6 (IL-6) with\r\ndopamine agonists in a culture of adenomatous cells from an nonfunctional macroadenoma.\r\nMaterials and methods. Tissue specimen from pituitary macroadenoma removed in transsphenoidal surgery was prepared for primary culture. Cells were counted and plated at 105/well into 24-well plates in a final volume of 1ml. Cabergoline in molar doses of 10-6, 10-7, 10-8, 10-9 was added and the cells were incubated for 4 days. sICAM-1, TNF-&#945;, IL-1&#945;, IL-6 were measured from cell-culture supernatants by ELISA kits.\r\nResults. sICAM-1, TNF-&#945;, IL-1&#945; and IL-6 were detected in the untreated control cultures after a 4d period. There was a negative correlation between TNF&#945; and IL-1&#945; (p=0.007).\r\nThe levels of PRL and hGH had measurable values above those found in culture medium without tumor cells. PRL positively correlated with IL-1&#945; ( p=0.05). hGH positively correlated with cell proliferation (p=0.049). Cabergoline treatment showed that IL-6 progressively decreased with the dose, ranging from -27.41% to -76.44%. TNF-&#945; significantly decreased (-65.90%; p<0.03)at the cabergoline 10-7 M dose. IL-1&#945; progressively increased with cabergoline dose, ranging\r\nfrom -2.53% to 345 %. sICAM-1 was significantly reduced by cabergoline at 10-9 (-47.12 %; p=0.045) and 10-6 M (-59.16%; p=0.01) doses. TNF-&#945; positively correlated with PRL (p=0.025); IL-6 positively correlated with hGH (p=0.044); sICAM-1 negatively correlated with hGH\r\n(p=0.009), TNF&#945; (p=0.025) and IL-1&#945; (p=0.044).\r\nConclusions. These data support the existence of an immunoendocrine network in pituitary tumorigenesis; TNF-&#945;, IL-6, IL-1&#945;, sICAM-1 significantly interfered by cabergoline\r\ntreatment in a dose-dependent way. However, future studies on different types of pituitary tumours are needed to confirm these findings.

    Spontaneous Conception and Term Delivery in a Woman with Ucontrolled Acromegaly and Hypogonadotropic Hypogonadism

    Acta Endo (Buc) 2016 12(4): 481-484 doi: 10.4183/aeb.2016.481

    Background. Patients with acromegaly (caused by growth-hormone-secreting pituitary adenomas) are at increased risk of hypopituitarism, in particular hypogonadotropic hypogonadism, before and after multimodal therapy. In affected women of reproductive age, fertility is impaired and complex fertility treatments are needed to achieve conception. C ase presentation. We present the case of a young woman with acromegaly caused by a GH-secreting macroadenoma with suprasellar and bilateral cavernous sinus extension; hypogonadotropic hypogonadism and secondary hypothyroidism were present from the initial evaluation. Neurosurgical intervention was repeatedly recommended but the patient refused it initially; also she was non-compliant to the medical treatment of acromegaly. Transsphenoidal tumor debulking with adjuvant gamma-knife radiotherapy was eventually performed. Following treatment persistent active acromegaly and hypogonadotropic hypogonadism were diagnosed. Under chronic estroprogestative replacement therapy, the patient conceived and delivered a full-term healthy newborn without any complications. Possible mechanisms are discussed. Conclusions. Secondary hypogonadotropic hypogonadism in pituitary patients, even when considered permanent (after surgery and radiotherapy), can exceptionally allow spontaneous conception and normal course of pregnancy.

    Craniopharyngioma - Clinical And Therapeutic Outcome Data in a Mixed Cohort of Adult and Paediatric Cases

    Acta Endo (Buc) 2018 14(4): 549-555 doi: 10.4183/aeb.2018.549

    Background. Craniopharyngiomas are benign but locally invasive tumours of the sellar region that arise from ectopic embryonic remnants of Rathke's pouch, affecting both children (adamantinomatous type -aCP) and adults (papillary type -pCP) and associated with significant morbidity. Objective. To study the clinical presentation of CRF as well as the posttreatment evolution of craniopharyngioma in children versus adults in a large mixed cohort. Material and methods. We performed a retrospective review of CRF patients evaluated in the National Institute of Endocrinology in Bucharest between 1990 and 2016. Results. A total of 107 patients (72 adults, 35 children) with a mean follow-up of 6.2 years were included. The presenting symptoms were mostly headache, visual impairment, symptoms of hypopituitarism, diabetes insipidus. Some symptoms or hormonal abnormalities were significantly more prevalent in the children group (p<0.05): nausea/ vomiting (47.8% vs 16.7%), photophobia (21.7% vs 5.6%), diabetes insipidus(28.5% vs 8.3%), GH deficiency (68.8% vs 17.1%). Impaired visual acuity (67.6%of cases) or visual fields (71.4%) were more frequent in adults compared to children (44.1%; 51.6%). The tumor dimensions were similar in both groups (3.05± 1.05 cm in children; 2.7± 1.07 cm in adults). Massive suprasellar extension reaching the third ventricle was frequently present in all cases. All cases underwent surgery but only a minority of those not cured received postoperative adjuvant radiotherapy. Frequent postoperative complications were: aggravation of the endocrine deficit (>80% of cases in both groups needed chronic replacement therapy), central diabetes insipidus (68.2% children, 34.3% of adults). Conclusions. Despite similar tumor dimensions and extension compared to adults, craniopharyngioma in children is more frequently associated with signs of intracranial pressure. The results and complications of treatment are similar in adults and children
