Context 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, 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-April 2020, the prevalence of symptomatic patients (complaining at least one symptom of viral infection) was similar between the two groups (24% in AI and 22.3% in controls, p 0.79). Highly suggestive COVID-19 symptoms (at least two 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 (two 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.

Adrenal insufficiency at the time of COVID-19: a retrospective study in patients referring to a tertiary centre.

Objective: high IGF-1 and unsuppressed 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 on 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 in this group is advised.

Objectiveprimary empty sella (PES) represents a frequent finding, but data on hormonal alterations are heterogeneous, and its natural history is still unclear. Our aim was to evaluate the pituitary function of patients with PES over a long follow-up.Designmulticenter retrospective cohort study enrolling patients referred between 1984-2020 to five Pituitary Units, with neuroradiological confirmed PES and a complete hormonal assessment.Methodswe analyzed hormonal (including basal and dynamic evaluations), clinical and neuroradiological data collected at diagnosis and at the last visit (at least 6 months of follow-up).Resultswe recruited 402 patients (females=63%, mean age=51.5 ± 16 years) with PES (partial, total, undefined in 66%, 13% and 21%, respectively). Hypopituitarism was present in 40.5% (hypogonadism=20.4%, hypoadrenalism=14.7%, growth hormone deficiency=14.7%, hypothyroidism=10.2%, diabetes insipidus=1.5%; multiple deficiencies=11.4%) and hypeprolactinemia in 6.5%. Interestingly, hormonal alterations were diagnosed in 29% of incidental PES. Hypopituitarism was associated with male sex (p=0.02), suspected endocrinopathy (p&lt;0.001), traumatic brain injury (p=0.003) and not with age, BMI, number of pregnancies and neuroradiological grade. A longitudinal assessment was possible in 166/402 (median follow-up=58 months). In 5/166 (3%), new deficiencies occurred, whereas 14/166 (8.4%) showed a hormonal recovery. A progression from partial to total PES, which was found in 6/98 patients assessed with a second imaging, was the only parameter significantly related to the hormonal deterioration (p=0.006).Conclusionsthis is the largest cohort of patients with PES reported. Hypopituitarism is frequent (40%) but hormonal deterioration seems uncommon (3%). Patients need to be carefully evaluated at diagnosis, even if PES is incidentally discovered.

Purpose GH deficit (GHD) could represent an endocrine issue in ß-Thalassemia Major (ßTM) patients. GH/IGF-1 axis has not been extensively explored in ßTM adults, so far. We aim to assess GHD and IGF-1 deficiency prevalence in ßTM adult population, focusing on the relationship with liver disease. Methods Cross-sectional multi-centre study conducted on 81 adult ßTM patients (44 males, mean age 41 ± 8 years) on transfusion and chelation therapy. GHD was investigated by GHRH + arginine test. IGF-1 levels, routine biochemical exams, Fibroscan, Hepatic Magnetic Resonance Imaging (MRI) and pituitary MRI were collected. Results Eighteen patients were affected by GHD and 63 were not (nGHD) according to GHRH + arginine test, while basal GH levels did not differ. GHD was associated with a higher BMI and a worse lipid profile (p < 0.05). No significant differences were observed regarding liver function between the two groups. Pituitary MRI scan was normal except for one case of empty sella. The 94.4% and 93.6% of GHD and nGHD, respectively, presented lower IGF-1 levels than the reference range, and mean IGF-1 SDS was significantly lower in GHD patients. Conclusion GHD is frequent in adult ßTM patients and is associated with higher BMI and worse lipid profile. nGHD patients present lower IGF-1 levels as well. There was no relationship between IGF-1 levels and liver disease. Further, multicentric studies with larger cohorts and standardized diagnostic protocols are needed.
