Predisposition to eating disorders in adults with type 1 diabetes: Comparison between multiple daily injections and continuous subcutaneous insulin infusion.

AIM: To evaluate predisposition to eating disorders (ED) or body dissatisfaction in adults with type 1 diabetes mellitus (T1DM); to further investigate any differences in ED predisposition between subjects with T1DM on multiple daily injections (MDI) or insulin pumps (CSII) and in respect to control healthy subjects. METHODS: We conducted a monocentric, cross-sectional, observational study. We enrolled subjects with T1DM, aged ≥ 18 years, and healthy subjects (HS) as control group. All participants completed two questionnaires to detect possible predisposition to ED: 34-items Body Shape Questionnaire (BSQ) and Eating Disorder Inventory-3 (EDI-3). HS only filled BSQ. For subjects with T1DM data about glycated hemoglobin and duration of disease were also collected. RESULTS: 162 subjects with T1DM (age 41 ± 12 years, 77 [47%] males) and 50 HS (age 38 ± 13 years, 18 (36%) males) were enrolled. 87 subjects with T1DM (54%) were on MDI and 75 (46%) were on CSII. No significant difference in the distribution of BSQ scores between subjects with T1DM and HS was observed (p = 0.551), although 16% of subjects with T1DM scored BSQ class 1 points while 8% of HS scored a BSQ class 1 points. No significant difference in BSQ scores was observed between subjects with T1DM on MDI or CSII. Between these two groups, no differences in EDI-3 scores were observed except for perfectionism score: subjects on MDI present more frequently a predisposition for perfectionism (p < 0.05) and, at a trend level, for bulimia. CONCLUSION: A non -significant higher percentage of BSQ class 1 was detected in subjects T1DM compared to healthy controls. Among subjects with T1DM, no differences between MDI and CSII were observed in ED predisposition. A more perfectionist personality has been detected among subjects on MDI.

Pregnancy and Prenatal Management of Congenital Adrenal Hyperplasia.

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive diseases that may cause cortisol insufficiency together with other hormonal alterations. The most common form is 21-hydroxylase deficiency, in which the lack of pituitary negative feedback causes an increase in ACTH and adrenal androgens. Classical forms of CAHs can lead to severe adrenal failure and female virilization. To date, the appropriate management of pregnant CAH patients is still debated regarding appropriate maternal therapy modifications during pregnancy and the risks and benefits of prenatal treatment of the fetus. We conducted a literature search of relevant papers to collect current evidence and experiences on the topic. The most recent and significant articles were selected, and current international guidelines were consulted to update current recommendations and guide clinical practice. Given the lack of randomized clinical trials and other high-quality scientific evidence, the issue is still debated, and great heterogeneity exists in current practice in terms of risk/benefit evaluation and pharmacological choices for pregnancy and prenatal treatment. Glucocorticoid therapy is advised not only in classical CAH patients but also in non-classical, milder forms. The choice of which glucocorticoid to use, and the safety and benefits of dexamethasone therapy aimed at preventing genital virilization are still debated issues. Several advances, however, have been made, especially in terms of fertility and reproduction. This review aims to present the most recent scientific and real-world updates on pregnancy and prenatal management of CAH, with the presentation of various clinical scenarios and specific case-by-case recommendations.

Medullary Thyroid Cancer with Ectopic Cushing's Syndrome: A Case Report and Systematic Review of Detailed Cases from the Literature.

Background: Medullary thyroid cancer (MTC) is a neuroendocrine tumor arising from parafollicular C-cells of the thyroid gland that, in rare cases, can cause a paraneoplastic ectopic Cushing's syndrome (ECS). The development of Cushing's syndrome (CS) in MTC patients is generally associated with advanced disease and poor prognosis. Summary: We described a case of severe CS due to MTC in a young male. We performed a systematic review to identify cases of ECS due to MTC. We searched PubMed, Scopus, and Web of Science for publications between database inception and February 2022 and we collected the patient characteristics, disease presentation, employed treatment strategies, and disease outcomes. In addition to our patient, we identified 96 cases of ECS due to MTC reported in literature. Mean age at diagnosis was 44.4 years (range 10-84), and there was a male predominance (male:female [M:F] = 1.8:1). Most patients (51%) presented with metastatic disease at diagnosis and showed severe hypercortisolism. Seventeen patients developed distant metastasis and hypercortisolism during follow-up. Interestingly, in 48% of patients, the diagnosis of CS followed the diagnosis of MTC with a median time of 48 months but, among patients in whom the diagnosis was concomitant (38%), symptoms due to hypercortisolism were frequently the reason for seeking medical advice. Pathology results showed evidence of adrenocorticotropic hormone (ACTH) or corticotropin releasing hormone (CRH) positive cells in 76% of patients in whom they were tested. The management of hypercortisolism was challenging in most patients with 48% requiring, eventually, definitive treatment with bilateral adrenalectomy (BLA). Recently, some limited evidence has emerged regarding tyrosine kinase inhibitors (TKIs) treatment for hypercortisolism in patients with ECS due to MTC. Despite limited information on survival, prognosis was generally poor and the main causes of death were either complications of CS or disease progression. Conclusions: Despite its rarity, MTC should be considered in the differential diagnosis of ECS. Management of hypercortisolism is a key factor to improve the patient's symptoms but it is often challenging and BLA is frequently required. Further studies are needed for investigating the role of TKIs in patients with MTC with ECS.

Genetic Basis of ACTH-Secreting Adenomas.

Cushing's disease represents 60-70% of all cases of Cushing's syndrome, presenting with a constellation of clinical features associated with sustained hypercortisolism. Molecular alterations in corticotrope cells lead to the formation of ACTH-secreting adenomas, with subsequent excessive production of endogenous glucocorticoids. In the last few years, many authors have contributed to analyzing the etiopathogenesis and pathophysiology of corticotrope adenomas, which still need to be fully clarified. New molecular modifications such as somatic mutations of USP8 and other genes have been identified, and several case series and case reports have been published, highlighting new molecular alterations that need to be explored. To investigate the current knowledge of the genetics of ACTH-secreting adenomas, we performed a bibliographic search of the recent scientific literature to identify all pertinent articles. This review presents the most recent updates on somatic and germline mutations underlying Cushing's disease. The prognostic implications of these mutations, in terms of clinical outcomes and therapeutic scenarios, are still debated. Further research is needed to define the clinical features associated with the different genotypes and potential pharmacological targets.
