OBJECTIVESome studies have highlighted psychological and neuropsychological difficulties and a potential reduction in health-related quality of life (HRQOL) in patients with pituitary tumors, despite hormone deficits or excess. To the authors’ knowledge, this study is the first prospective longitudinal case-control study with the aim of simultaneously testing whether HRQOL and psychiatric and neuropsychological disabilities are related to neural dysfunction due to hypercortisolism per se, or tumor mass and/or surgery in patients with Cushing’s disease (CD). The authors evaluated a homogeneous cohort of patients with CD and nonfunctioning pituitary adenomas (NFPAs) before and after neurosurgery and compared these patients with healthy controls.METHODSTwenty patients (10 with NFPA and 10 with CD) were evaluated using 3 validated questionnaires (SF-36, Beck Depression Inventory–II [BDI-II], and Minnesota Multiphasic Personality Inventory–II [MMPI-II]) to assess HRQOL and psychological status preoperatively and 12 months after neurosurgery. Neuropsychological tests were assessed preoperatively, 3–7 days postoperatively, and 12 months postoperatively. Twenty healthy matched controls were recruited.RESULTSPreoperatively, the NFPA and CD subgroups had worse HRQOL scores than controls on the basis of SF-36 scores, although the NFPA subgroup experienced significant recovery 12 months postoperatively. Preoperatively, CD patients had depressive symptoms according to the BDI-II and MMPI-II that persisted 12 months postoperatively, together with social introversion and hypochondriasis; NFPA patients were similar to controls except for hypochondriasis scores that were clinically significant at all timepoints. Preoperatively and 3–7 days postoperatively, both subgroups showed significant neuropsychological disabilities compared with controls, but only the CD subgroup did not completely recover over time.CONCLUSIONSHRQOL and neuropsychological impairments were observed in all patients at early timepoints, independent of hypercortisolism, tumor mass, and successful surgery. Over time, CD patients showed persistent changes in HRQOL, in particular in social activities. In this light, CD seems to have a strong impact on HRQOL and to be associated with more psychological and neuropsychological comorbidities than NFPA.

Aneurysmal bone cysts (ABCs) are rare benign pseudotumoral bone lesions with potential aggressive behavior due to the extensive destruction of surrounding bone. Traditionally, these tumors were treated with open surgery, but there is more and more a shift to less invasive procedures. In particular, treatment for spinal ABCs is generally unsatisfactory due to the risk of morbidity, neurological impairment and recurrence, and there is a need for innovative therapies. Denosumab has been reported as a useful treatment in giant cell tumors of bone (GCTB), so its efficacy has been tested also in other fibro-osseus lesions affecting children and adolescents, such as spinal aneurysmal bone cysts. The pediatric literature is limited to case reports and small series, all of which highlight the efficacy of this treatment on lesions growth and associated bone pain. Some of these reports have already reported well known side effects associated with denosumab, such as hypocalcemia at the beginning of the treatment, and rebound hypercalcemia at the discontinuation. The latter seems to be more frequent in children and adolescents than in adults, probably due to the higher baseline bone turnover in children. In addition, the use of denosumab in young patients could affect both bone modeling and remodeling, even if the consequences on the growing skeleton have not been reported in detail. Here we describe the case of a spinal ABC diagnosed in an 8-year old young boy which was not accessible to surgery but responded favorably to denosumab. Our aim is to describe the rapid changes in mineral and bone homeostasis in this patient, that required advice from the experts of the European Reference Network (ERN) for rare bone and endocrine diseases.

Introduction: Available data on pituitary incidentalomas mostly derive from small-scale studies, with heterogeneous inclusion criteria and limited follow-up. No paper has focused specifically on clinically nonfunctioning pituitary in­cidentalomas (CNFPIs). Objective: To describe the charac­teristics and the natural history of patients diagnosed with CNFPIs. Methods: Retrospective multicenter cohort study evaluating hormonal, imaging, and visual field characteristics at diagnosis and during follow-up of CNFPIs investigated in 2 Pituitary Centers. Results: Three hundred and seventy-one patients were included (50.9% microadenomas, 35.6% males). Men were older and more likely to have a macroadenoma (p < 0.01). Totally, 23.7% of patients presented secondary hormonal deficits (SHDs), related to tumor size (higher in macroadenomas; p < 0.001) and age (higher in older patients; p < 0.001). Hypogonadism was the most frequent SHD (15.6%). Two hundred and ninety-six patients had follow-up data, 29.1% required surgery after first evaluation, and 97 had at least 3 years of follow-up. In total, 15.3% adenomas grew (more macroadenomas), but only in microadenomas patients with longer follow-up showed a higher growth trend. Totally, 5.2% of patients developed new SHDs (micro- vs. macroadenomas p = 1.000), and in 60% of them this was not associated with an increase in tumor size. Thirteen additional patients required surgery during follow-up (1 microadenoma at diagnosis). Conclusions: Macroadenomas and age are risk factors for SHD in CNFPIs, which occur at diagnosis in a quarter of patients. During follow-up, macroadenomas tend to grow more often, but microadenomas display higher growth trend as follow-up increases. Deterioration of pituitary function is not always related to adenoma growth.

Objective High insulin-like growth factor 1 (IGF-1) and unsuppressed growth hormone (GH) levels after glucose load confirm the diagnosis of acromegaly. Management of patients with conflicting results could be challenging. Our aim was to evaluate the clinical and hormonal evolution over a long follow-up in patients with high IGF-1 but normal GH nadir (GHn < 0.4 μg/L according to the latest guidelines). Design Retrospective cohort study. Methods We enrolled 53 patients presenting high IGF-1 and GHn < 0.4 μg/L, assessed because of clinical suspicion of acromegaly or in other endocrinological contexts (e.g. pituitary incidentaloma). Clinical and hormonal data collected at the first and last visit were analyzed. Results At the first evaluation, the mean age was 54.1 ± 15.4 years, 34/53 were females, median IGF-1 and GHn were +3.1 SDS and 0.06 μg/L, respectively. In the whole group, over a median time of 6 years, IGF-1 and GHn levels did not significantly change (IGF-1 mean of differences: −0.58, P = 0.15; GHn +0.03, P = 0.29). In patients with clinical features of acromegaly, the prevalence of acromegalic comorbidities was higher than in the others (median of 3 vs 1 comorbidities per patient, P = 0.005), especially malignancies (36% vs 6%, P = 0.03), and the clinical worsening overtime was more pronounced (4 vs 1 comorbidities at the last visit). Conclusions In patients presenting high IGF-1 but GHn < 0.4 μg/L, a hormonal progression is improbable, likely excluding classical acromegaly in its early stage. However, despite persistently low GH nadir values, patients with acromegalic features present more acromegalic comorbidities whose rate increases over time. Close clinical surveillance of this group is advised.

Context Coronavirus disease 2019 (COVID-19) represents a global health emergency, and infected patients with chronic diseases often present with a severe impairment. Adrenal insufficiency (AI) is supposed to be associated with an increased infection risk, which could trigger an adrenal crisis. Objective Our primary aim was to evaluate the incidence of COVID-19 symptoms and complications in AI patients. Design and Setting We conducted a retrospective case-control study. All patients were on active follow-up and lived in Lombardy, Italy, one of the most affected areas. Patients We enrolled 279 patients with primary and secondary AI and 112 controls (patients with benign pituitary lesions without hormonal alterations). All AI patients had been previously trained to modify their replacement therapy on stress doses. Intervention By administering a standardized questionnaire by phone, we collected data on COVID-19 suggestive symptoms and consequences. Results In February through April 2020, the prevalence of symptomatic patients (complaining at least 1 symptom of viral infection) was similar between the 2 groups (24% in AI and 22.3% in controls, P = 0.79). Highly suggestive COVID-19 symptoms (at least 2 including fever and/or cough) also occurred equally in AI and controls (12.5% in both groups). No patient required hospitalization and no adrenal crisis was reported. Few nasopharyngeal swabs were performed (n = 12), as indicated by sanitary regulations, limiting conclusions on the exact infection rate (2 positive results in AI and none in controls, P = 0.52). Conclusions AI patients who are adequately treated and trained seem to display the same incidence of COVID-19-suggestive symptoms and disease severity as controls.

Background Vertebral fractures (VFs) are a frequent complication of acromegaly, but no studies have been so far published on effectiveness of antiosteoporotic drugs in this clinical setting. Objective To evaluate whether in real-life clinical practice bone active drugs may reduce the risk of VFs in patients with active or controlled acromegaly. Study design Retrospective, longitudinal study including 9 tertiary care endocrine units. Patients and Methods Two hundred and forty-eight patients with acromegaly (104 males; mean age 56.00 ± 13.60 years) were evaluated for prevalent and incident VFs by quantitative morphometric approach. Bone active agents were used in 52 patients (20.97%) and the median period of follow-up was 48 months (range 12-132). Results During the follow-up, 65 patients (26.21%) developed incident VFs in relationship with pre-existing VFs (odds ratio [OR] 3.75; P Conclusions Bone active drugs may prevent VFs in patients with active acromegaly.

Background: Cushing disease (CD) represents the principal cause of endogenous hypercortisolism. The first-line therapy of CD is surgical removal of the ACTH-secreting pituitary adenoma, which is generally followed by adrenal insufficiency (AI). Objective: To analyze the recovery of AI in patients with CD after pituitary surgery in relation with recurrence and persistent remission of CD. Patients and Methods: We performed a retrospective analysis of patients with CD who met the following inclusion criteria: adult age, presence of AI 2 months after the surgical intervention, and a minimum follow-up of 3 years after the surgical intervention. Results: Sixty-one patients were followed for a median of 6 years. Ten (16.4%) patients recurred during follow-up. The patients who restored adrenal function did so after a median time of 19 months, with a significantly shorter time in the recurrence group (12.5 vs. 25 months, p = 0.008). All 10 patients who recurred recovered their adrenal function within 22 months. The recovery rate of AI in the persistent remission group was 37.3% (19/51) at 3 years and 55.8% (24/43) at 5 years. In all patients the duration of AI was negatively associated with disease recurrence. Conclusion: The duration of postsurgical AI in patients with recurrent CD is significantly shorter than that in patients with persistently remitted CD, and this parameter may be a useful predictor of recurrence. Patients showing a normal pituitary-adrenal axis within 2 years after surgery should be strictly monitored as they are at higher risk of disease relapse.
