In Romania, acromegaly benefits from the whole spectrum of therapeutic interventions. However, the control rate remains disappointing.

ACM pts present LV concentric hypertrophy and LV systolic and diastolic dysfunction, even in controlled disease. Altered global LV systolic function appears to be due both to longitudinal and radial dysfunction.

Background.Germline aryl hydrocarbon receptor-interacting protein (AIP) mutations are found in familial isolated pituitary adenoma syndrome (FIPA) families and in a small number of sporadic pituitary adenoma (PA) patients. Although the tumorigenic mechanisms of AIP mutations are unclear, truncating mutations are considered pathogenic, but missense mutations are difficult to evaluate. p.R16H (c.47G>A) is a controversial AIP variant of unknown significance.Aim. To describe a new PA case associated with AIP p.R16H.Patients and methods. One AIP p.R16H non-functioning pituitary adenoma (NFPA) case identified by mutation sequencing screening of sporadic PA patients; 108 controls were screened for p.R16H.Results. The 38 yrs old male NFPA patient had no family history of PA and harboured a heterozygous p.R16H variant. The proband and two brothers presented severe intellectual disability. Severe visual impairment was the initial symptom and clinical, biochemical and imaging examination demonstrated a large NFPA invading the right cavernous sinus. After transsphenoidal debulking, the remaining tumor continued growth. One of proband's sisters was negative for p.R16H. Among controls, we identified one heterozygous p.R16H carrier, presenting a thyroid follicular neoplasm. Loss of heterozygosity analysis of the pituitary and thyroid tumors was not performed.Conclusions. We report two new occurrences of AIP p.R16H, associated with a NFPA and with a thyroid tumor. The NFPA patient was young and presented an invasive macroadenoma, features typical of AIP-mutated patients. Because the association between p.R16H and PAs has not been conclusively established, further research of p.R16H is warranted, in view of its implications for AIP genetic testing.

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. case 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.
