Since the emergence of the COVID-19 pandemic at the end of 2019, a massive vaccination campaign has been undertaken rapidly and worldwide. Like other vaccines, the COVID-19 vaccine is not devoid of side effects. Typically, the adverse side effects of vaccination include transient headache, fever, and myalgia. Endocrine organs are also affected by adverse effects. The major SARS-CoV-2 vaccine-associated endocrinopathies reported since the beginning of the vaccination campaign are thyroid and pancreas disorders. SARS-CoV-2 vaccine-induced pituitary diseases have become more frequently described in the literature. We searched PubMed/MEDLINE for commentaries, case reports, and case series articles reporting pituitary disorders following SARS-CoV-2 vaccination. The search was reiterated until September 2022, in which eight case reports were found. In all the cases, there were no personal or familial history of pituitary disease described. All the patients described had no previous SARS-CoV-2 infection prior to the vaccination episode. Regarding the type of vaccines administered, 50% of the patients received (BNT162b2; Pfizer–BioNTech) and 50% received (ChAdOx1 nCov-19; AstraZeneca). In five cases, the pituitary disorder developed after the first dose of the corresponding vaccine. Regarding the types of pituitary disorder, five were hypophysitis (variable clinical aspects ranging from pituitary lesion to pituitary stalk thickness) and three were pituitary apoplexy. The time period between vaccination and pituitary disorder ranged from one to seven days. Depending on each case’s follow-up time, a complete remission was obtained in all the apoplexy cases but in only three patients with hypophysitis (persistence of the central diabetes insipidus). Both quantity and quality of the published data about pituitary inconveniences after COVID-19 vaccination are limited. Pituitary disorders, unlike thyroid disorders, occur very quickly after COVID-19 vaccination (less than seven days for pituitary disorders versus two months for thyroid disease). This is partially explained by the ease of reaching the pituitary, which is a small gland. Therefore, this gland is rapidly overspread, which explains the speed of onset of pituitary symptoms (especially ADH deficiency which is a rapid onset deficit with evocative symptoms). Accordingly, these pilot findings offer clinicians a future direction to be vigilant for possible pituitary adverse effects of vaccination. This will allow them to accurately orient patients for medical assistance when they present with remarkable symptoms, such as asthenia, polyuro-polydipsia, or severe headache, following a COVID-19 vaccination.

Diagnosis of adrenal insufficiency requires evaluation by dynamic stimulation tests. The insulin tolerance test (ITT) is accepted as the gold-standard test for the evaluation of hypothalamo-pituitary-adrenal (HPA) axis but the test is unpleasant and dangerous. Although it takes more time, glucagon stimulation test (GST) is a good alternative to ITT. The primary aim of this study was to compare the ITT and GSTs in the evaluation of HPA axe in patients with pituitary disorders. We conducted a prospective study in which ITT and GST were performed within 7 days in 81 patients. Serum cortisol was measured. We divided our population in Group 1 (G1): Adrenal Insufficiency (Peak cortisol under ITT 200 ng/mL). Receiver-operating characteristic (ROC) analysis was performed to identify the thresholds for GST. The mean peak of cortisol under GST was not significantly different from that obtained after ITT in the whole cohort (182.67 +/- 89.07 ng/mL vs. 179.75 +/- 79.01 ng/mL), and it was significantly reduced in patients of G1 (p < 10(-3)). ROC curve analysis showed that the best diagnostic accuracy was obtained with a peak cortisol cut-off to GST of 167 ng/int, (sensitivity, 89%; specificity, 79%). Using this cut-off, 86.4% of the patients were correctly classified. In our prospective series, GST is a potential accurate and safe alternative test for the assessment HPA. Test-specific cut-offs should be applied to avoid misinterpretation.

Context In some patients, symptoms may persist after COVID-19, defined as long COVID. Its pathogenesis is still debated and many hypotheses have been raised. Objective Our primary objective was to evaluate the corticotroph and somatotroph functions of patients previously infected with SARS-CoV-2 and experiencing post–COVID-19 syndrome to detect any deficiencies that may explain long COVID. Methods A cross-sectional study was conducted including patients who had previously contracted SARS-CoV-2 with a postinfection period of 3 months or less to 15 months, divided into 2 groups. The first group (G1) comprised fully recovered patients, while the second group (G2) included patients experiencing long COVID. The primary outcome was the comparison of corticotroph and somatotroph functions. Results A total of 64 patients were divided into 2 groups, each consisting of 32 patients. G2 exhibited more frequently anterior pituitary deficits compared to G1 (P = .045): for the corticotroph axis (G1: 6.3% vs G2: 28.1%) and for the somatotroph axis (G1: 31.3% vs G2: 59.4%). Baseline cortisol level was significantly lower in G2 (G1: 13.37 µg/dL vs G2: 11.59 µg/dL) (P = .045). The peak cortisol level was also lower in G2 (G1: 23.60 µg/dL vs G2: 19.14 µg/dL) (P = .01). For the somatotroph axis, the insulin growth factor-1 level was lower in G2 (G1: 146.03 ng/mL vs G2: 132.25 ng/mL) (P = .369). The peak growth hormone level was also lower in G2 (G1: 4.82 ng/mL vs G2: 2.89 ng/mL) (P = .041). Conclusion The results showed that long COVID patients in our cohort were more likely to have anterior pituitary deficiencies. The endocrine hypothesis involving anterior pituitary insufficiency can be considered to explain long COVID.

A multidisciplinary team is composed of various healthcare professionals that ensure a multifaceted approach on a group of patients. Standards for diabetes medical care note the importance of multidisciplinary diabetes care teams. We applied our model of multidisciplinary approach by structuring it in a determined five days hospitalization. The aim of this study was to determine if the interdisciplinary approach applied on a short hospitalization is of benefit in patients with poorly controlled diabetes mellitus. Sixty-seven patients were included and ensured a short hospitalization in which they received a multiple educational advice and a treatment adaptation. Sixty-one patients out of 67 (91%) were retained for evaluation with sufficient data at one year, i.e. 9% of patients with poor compliance. Evolution in glycosylated haemoglobin (HbA1c), weight and treatments was analyzed. After a 12 months followup, we observed significant improvement in HbA1c (-1.73%; p < 10(3)) without weight loss (BMI=-0.42 kg/m(2)), p=0.28). HbA1c mean levels correlated negatively to body mass index (BMI) during the regular follow-up (r=-0.22, p=0.05). More than 90% of patients with poorly controlled diabetes mellitus responded to the multi-disciplinary approach with a decrease in HbA1c.

Polycystic ovary syndrome is a presvalent endocrine disorder affecting women globally, characterized by hormonal imbalance, metabolic disturbances, and reproductive dysfunction. Diagnosis relies on clinical evaluation, medical history assessment, physical examination, and laboratory tests, with the Rotterdam criteria being widely used. The pathophysiology of PCOS involves genetic predisposition, environmental factors, and lifestyle influences, with hormonal dysregulation, particularly elevated androgens, insulin resistance, and chronic inflammation, playing a pivotal role. These mechanisms not only contribute to reproductive and metabolic disturbances but also to the various cutaneous manifestations, such as acne, hirsutism, and alopecia. This review aims to analyze the role of androgens in the dermatological manifestations in patients with polycystic ovary syndrome, providing insights into underlying mechanisms and guiding the development of effective therapeutic strategies. By synthesizing available evidence, this review aims to deepen understanding of related dermatological manifestations and improve outcomes for affected individuals.
