Pituitary stalk interruption syndrome (PSIS) is a rare hypothalamic-pituitary disorder causing progressive anterior pituitary deficiency. Subtle early symptoms and unreliable sex hormone levels in prepubertal patients complicate diagnosis of anterior pituitary deficiency. This study aimed to investigate the association between serum prolactin (PRL) levels and anterior pituitary deficiency in PSIS patients, as well as its potential as a biomarker for complete anterior pituitary deficiency (CAPD). This retrospective study analyzed 155 patients with PSIS diagnosed and treated at the Chinese People’s Liberation Army General Hospital. We assessed the association between PRL levels and the severity of pituitary function deficits as well as testicular volume, and further evaluated its diagnostic value for CAPD. Among 155 patients with pituitary stalk interruption syndrome (89.03
This study aims to investigate the clinical characteristics of programmed cell death protein-1 (PD-1) or programmed cell death ligand-1 (PD-L1) inhibitors-induced pituitary injury (pituitary-irAE) by comparing with other pituitary diseases. We retrospectively reviewed clinical records of patients who were admitted for pituitary-irAE, idiopathic isolated ACTH deficiency (IIAD), and lymphocytic hypophysitis (LYH) from January 2015 to June 2024. Among 3689 patients treated with PD-1/PD-L1 inhibitors, 0.596% patients developed pituitary-irAE. The mean age of onset was 59.41 ± 10.69 years, with 13 patients (59.09%) being male. The median duration from symptom onset to confirmed diagnosis was 5.50 (2.00, 9.25) months. The clinical symptoms were similar between pituitary-irAE and IIAD, which mainly manifested as fatigue and appetite loss. Polydipsia/polyuria and amenorrhea/menstrual disorders were mainly found in patients with LYH. Central adrenal insufficiency was observed in all patients with pituitary-irAE, with cortisol concentrations typically falling below the detectable limit. Pituitary MRI appeared normal in 52.63% patients with pituitary-irAE. Furthermore, some patients with pituitary-irAE exhibited partial or complete functional recovery of the pituitary gland after hormone replacement therapy. The clinical manifestations observed in patients with pituitary-irAE are analogous to those seen in individuals with IIAD, yet they differ from the presentations of LYH.
Pituitary stalk interruption syndrome (PSIS) is an infrequently occurring congenital condition, and there exists a dearth of systematic investigative work focusing on the clinical features and long-term outcomes in adult patients. Individuals who have reached adulthood with PSIS are at an increased risk of developing metabolic disorders, including metabolic syndrome (MS) and non-alcoholic fatty liver disease (NAFLD) or metabolic dysfunction associated fatty liver disease (MAFLD), which are also one of the main factors for the poor prognosis of these patients. An analysis was conducted on the clinical data of adult PSIS patients who visited the endocrinology department of the First Medical Center of the People’s Liberation Army General Hospital from January 2005 to August 2023. Patients were grouped based on their MAFLD and MS status, and the differences in clinical characteristics and risk factors between the groups were analyzed. Machine learning models were used to construct a prediction model for the occurrence of MAFLD in adult PSIS patients and to analyze high-risk predictors. Out of 136 PSIS adult patients, 93.3% were male. The prevalence of MAFLD was 55.5%, and MS was 22.3%. Patients with a history of growth hormone (GH) treatment were less likely to develop MAFLD (P = 0.032). MAFLD patients exhibited higher rates of hypertension, hyperuricemia, obesity, MS, and dyslipidemia. Multiple risk factors may contribute to MS, while no significant link was found between MS and hormone replacement. However, GH non-treatment may serve as the notable predictor of MAFLD in PSIS patients revealed by the Ridge regression model of machine learning model with the highest predictive performance of a mean area under the curve (AUC) of 0.82. The prevalence of MS and MAFLD is high among adult patients with PSIS. Multiple risk factors may contribute to these two diseases, and after constructing a predictive model, we found that MAFLD may be closely linked to the previous lack of GH treatment.
The 3D human pituitary organoid represents a promising laboratory model for investigating human pituitary diseases. Nonetheless, this technology is still in its nascent stage, with uncertainties regarding the cellular composition, intercellular interactions, and spatial distribution of the human pituitary organoids. To address these gaps, the culture conditions are systematically adjusted and the efficiency of induced pluripotent stem cells' (iPSCs') differentiation into pituitary organoids is successfully improved, achieving results comparable to or exceeding those of previous studies. Additionally, single-cell RNA-sequencing (scRNA-seq) and stereomics sequencing (Stereo-seq) are performed on the pituitary organoids for the first time, and unveil the diverse cell clusters, intricate intercellular interactions, and spatial information within the organoids. Furthermore, the SOX3 gene interference impedes the iPSCs' differentiation into pituitary organoids, thereby highlighting the potential of pituitary organoids as an ideal experimental model. Altogether, the research provides an optimized protocol for the human pituitary organoid culture and a valuable transcriptomic dataset for future explorations, laying the foundation for subsequent research in the field of pituitary organoids or pituitary diseases.
BackgroundPituitary stalk interruption syndrome (PSIS) is a complex clinical syndrome characterized by varied pituitary hormone deficiencies, leading to severe manifestations across multiple systems. These include lifelong infertility, short stature, mental retardation, and potentially life-threatening pituitary crises if not promptly diagnosed and treated. Despite extensive research, the precise pathogenesis of PSIS remains unclear. Currently, there are two proposed theories regarding the pathogenic mechanisms: the genetic defect theory and the perinatal injury theory.MethodsWe systematically searched English databases (PubMed, Web of Science, Embase) and Chinese databases (CNKI, WanFang Med Online, Sinomed) up to February 24, 2023, to summarize studies on gene sequencing in PSIS patients. Enrichment analyses of reported mutated genes were subsequently performed using the Metascape platform.ResultsOur study included 37 articles. KEGG enrichment analysis revealed mutated genes were enriched in the Notch signaling pathway, Wnt signaling pathway, and Hedgehog signaling pathway. GO enrichment analysis demonstrated mutated genes were enriched in biological processes such as embryonic development, brain development, axon development and guidance, and development of other organs.ConclusionBased on our summary and analyses, we propose a new hypothesis: disruptions in normal embryonic development, partially stemming from the genetic background and/or specific gene mutations in individuals, may increase the likelihood of abnormal fetal deliveries, where different degrees of traction during delivery may lead to different levels of pituitary stalk interruption and posterior lobe ectopia. The clinical diversity observed in PSIS patients may result from a combination of genetic background, specific mutations, and variable degrees of traction during delivery.
The clinical data, laboratory test, and gene mutations were collected from a family with Liddle syndrome. Literatures on Liddle syndrome published in domestic and abroad since 1994 were reviewed and the types of gene mutations were summarized. The proband was diagnosed with hypertension at the age of 24. Laboratory test showed that serum potassium was 3.65 mmol/L, plasma renin was <0.5 mU/L, and plasma aldosterone was 1.5 ng/dL. Proband′s father was diagnosed with hypertension at the age of 34 with the serum potassium 3.34 mmol/L, plasma renin 3.72 mU/L, and plasma aldosterone 6.04 ng/dL. A nonsense mutation(1724G>A, p.Trp575*) in exon 13 of SCNN1G gene was detected in the proband and his father. In 288 cases from 107 families reported in the review of domestic and foreign literature, the incidence of hypertension, hypokalemia, and low renin/low aldosterone were 95.1%, 55.2%, and 49.6%, respectively. This case suggests that the clinical phenotype of Liddle syndrome is heterogeneous. Patients with early-onset hypertension, regardless of whether they are accompanied by hypokalemia, should be screened for renin-angiotensin-aldosterone and genetic testing related to Liddle syndrome should be further detected in patients with low plasma renin/aldosterone.

Objective:To summarize the clinical characteristics, reveal evolutionary patterns, and enhance the understanding of idiopathic isolated adrenocorticotripin(ACTH)deficiency(IIAD)by conducting a clinical analysis and follow-up.Methods:The clinical data of 12 patients with IIAD in our center were analyzed retrospectively, and the patients were further followed up to summarize the clinical characteristics of these patients.Results:Among 12 patients with IIAD, the ratio of male to female was 3∶1. The onset showed a bimodal trend, with 2 cases occurring below the age of 18(at 1 year and 11 years respectively), and 10 cases occurring in adults, with an average onset age of 59.4 years old. In adults, the main symptoms were chronic fatigue, anorexia, and weight loss, while pediatric patients exhibited hypoglycemia and seizures. Hyponatremia(50%)was a common biochemical abnormality. ACTH, cortisol, and 24 h urinary free cortisol were significantly lower in all patients, and the functions of other pituitary gland axes were normal. All patients were normal except 2 patients with pituitary MRI showing vacuolar sella turcica. The most common accompanying disease was Hashimoto thyroiditis. After glucocorticoid replacement therapy, all patients showed symptom improvement. The replacement doses include prednisone acetate at 2.5-7.5 mg/d or hydrocortisone at 12-20 mg/d. All the 8 patients were still alive with ongoing ACTH deficiency, without any decline in other pituitary axis functions or occurrence of other diseases.Conclusion:IIAD exhibits a bimodal onset pattern with a higher prevalence in males. Symptoms persist in a chronic and stable manner without remission. Prognosis is favorable with physiological dose of glucocorticoid replacement therapy.

The present study aimed to investigate the association between insulin resistance (IR), nitric oxide (NO) production and myocardial apoptosis in a background of coexisting hypertension in a rodent animal model. A hypertensive rat model was established by feeding Wistar and spontaneously hypertensive rats (SHR) with a high sucrose/fat (HSF) diet for 12 weeks, in conjunction with isosorbide mononitrate (ISMN). Increased IR, NO content, apoptotic gene and protein expression, and morphological alterations within rat myocardium were evaluated. Following a total of 12 weeks of feeding with HSF and ISMN resulted in increased IR and NO content within the myocardial tissue of Wistar and SHR rats. HSF and ISMN activated myocardial apoptosis by downregulating the gene transcription and protein expression levels of the anti‑apoptotic B‑cell lymphoma 2 (Bcl‑2), and increasing the pro‑apoptotic Bcl‑2 associated X protein. Apoptosis was demonstrated by DNA fragmentation in terminal deoxynucleotidyl‑transferase‑mediated dUTP nick end labelling assay. In all experiments, the combination of HSF and ISMN was associated with more pronounced effects, indicating the possible synergistic effects. In addition, the correlation analysis in the Wistar rats fed with HSF only, revealed a positive association between NO production and IR. The results of the present study indicated that HSF and ISMN simultaneously increased IR, NO production and myocardial apoptosis in the hypertensive rat model, and may therefore contribute to investigations into the long‑term clinical use of ISMN in hypertensive patients.
