This disorder causes an inability to convert androgens into estrogens, resulting in excess androgens and estrogen deficiency. AED is typically diagnosed in female infants, but diagnosis in men is often delayed until adulthood due to late-onset skeletal and metabolic issues. We report the case of a 31-year-old male referred for increased height and bone discomfort. Over the past 6 years, his height had increased by 5 cm, accompanied by leg cramps and bone pain. He had a height of 193 cm, weighed 103 kg, and presented with a eunuchoid body habitus. The patient's height was above/at + 2 SD from target height. Laboratory findings revealed elevated FSH, LH, and testosterone, with undetectable estrogen levels. Serum osteocalcin and alkaline phosphatase were elevated. X-rays showed incomplete epiphyseal fusion. Bone densitometry revealed Z scores of -2 (lumbar spine) and - 2.6 (femoral neck). Genetic testing confirmed a homozygous exon 6 deletion in CYP19A1. The patient was treated with transdermal estradiol (25 µg twice weekly), which normalized estradiol, testosterone, and gonadotropin levels. Epiphyseal fusion occurred within 6 months. Aromatase deficiency in men frequently goes undiagnosed until adulthood. Timely diagnosis is crucial to initiating estrogen treatment early after puberty to prevent skeletal problems linked to this disorder.</p>","PeriodicalId":50399,"journal":{"name":"Hormones-International Journal of Endocrinology and Metabolism","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143568615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The timing of menarche determines the timing of later phases of pubertal maturation in girls and has major implications for health later in life, including behavioral and psychosocial disorders during adolescence and fertility problems and increased risk for certain diseases in adulthood. Over the last few decades, a continuous decline in age at menarche has been noted, with environmental factors contributing to this change in the timing of menarche. However, a genetic component of age at menarche and pubertal onset has been strongly suggested by studies in families and twins wherein up to approximately 80% of the variance in puberty onset can be explained by heritability. Gene association studies have revealed several genetic loci involved in age at menarche, among which LIN28B has emerged as a key regulator of female growth and puberty. LIN28B, a human homolog of Lin28 of C. elegans, is a known RNA-binding protein that regulates let-7 microRNA biogenesis. Genome-wide association studies have identified the association of polymorphisms in the LIN28B gene with age at menarche in several population cohorts worldwide.

Recently, a novel cluster-based diabetes classification was proposed which may offer the possibility to solve this problem. In this study, we report our performance of cluster analysis of individuals newly diagnosed with T2DM, our exploration of each subtype's clinical characteristics and medication treatment, and the comparison carried out concerning the risk for diabetes complications and comorbidities among subtypes by adjusting for influencing factors. We hope to promote the further application of cluster analysis in individuals with early-stage T2DM.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;In this study, a k-means cluster algorithm was applied based on five indicators, namely, age, body mass index (BMI), glycosylated hemoglobin (HbA1c), homeostasis model assessment-2 insulin resistance (HOMA2-IR), and homeostasis model assessment-2 β-cell function (HOMA2-β), in order to perform the cluster analysis among 567 newly diagnosed participants with T2DM. The clinical characteristics and medication of each subtype were analyzed. The risk for diabetes complications and comorbidities in each subtype was compared by logistic regression analysis.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The 567 patients were clustered into four subtypes, as follows: severe insulin-deficient diabetes (SIDD, 24.46%), age-related diabetes (MARD, 30.86%), mild obesity-related diabetes (MOD, 25.57%), and severe insulin-resistant diabetes (SIRD, 20.11%). According to the results of the oral glucose tolerance test (OGTT) and biochemical indices, fasting blood glucose (FBG), 2-hour postprandial blood glucose (2hBG), HbA1c, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and triglyceride-glucose index (TyG) were higher in SIDD and SIRD than in MARD and MOD. MOD had the highest fasting C-peptide (FCP), 2-hour postprandial C-peptide (2hCP), fasting insulin (FINS), 2-hour postprandial insulin (2hINS), serum creatinine (SCr), and uric acid (UA), while SIRD had the highest triglycerides (TGs) and TyG-BMI. Albumin transaminase (ALT) and albumin transaminase (AST) were higher in MOD and SIRD. As concerms medications, compared to the other subtypes, SIDD had a lower rate of metformin use (39.1%) and a higher rate of α-glucosidase inhibitor (AGI, 61.7%) and insulin (74.4%) use. SIRD showed the highest frequency of use of sodium-glucose cotransporter-2 inhibitors (SGLT-2i, 36.0%) and glucagon-like peptide-1 receptor agonists (GLP-1RA, 19.3%).

Moreover, studies have shown that physical exercise (PE) is not only a promising non-pharmacological strategy for AD prevention and treatment but can also lead to an increase in melatonin levels. Hence, we hypothesized that PE can contribute to AD prevention and treatment by increasing melatonin levels and reducing Aβ accumulation, enhancing Aβ clearance, and modulating inflammation in these patients.
