Lifestyle measures (LSMs) should be the first-line approach offered for obesity-related functional hypogonadism (FH). When LSMs fail, the role of testosterone replacement treatment (TRT) is unclear. GLP1 receptor agonist liraglutide is linked to progressive and sustained weight loss. A potential direct impact of GLP1 on hypothalamus-pituitary-testicular (HPT) axis was reported in animal models. We aimed to compare the effects of liraglutide and TRT on FH in obese men that had been poor responders to LSM, by means of reversal of FH and weight reduction. We designed a 16-week prospective randomized open-label study with 30 men (aged 46.5 ± 10.9 years, BMI 41.2 ± 8.4 kg/m2, mean ± s.d.) that were randomized to liraglutide 3.0 mg QD (LIRA) or 50 mg of 1% transdermal gel QD (TRT). Sexual function and anthropometric measures were assessed. Fasting blood was drawn for determination of endocrine and metabolic parameters followed by OGTT. Model-derived parameters including HOMAIR and calculated free testosterone (cFT) were calculated. Total testosterone significantly increased in both arms (+5.9 ± 7.2 in TRT vs +2.6 ± 3.5 nmol/L in LIRA) and led to improved sexual function. LIRA resulted in a significant increase of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) (P < 0.001 for between-treatment effect). Subjects treated with LIRA lost on average 7.9 ± 3.8 kg compared with a 0.9 ± 4.5 kg loss in TRT (P < 0.001). Metabolic syndrome was resolved in two patients in LIRA and in no subjects in TRT. Liraglutide was superior to TRT in improving an overall health benefit in men with obesity-associated FH after LSM failed.
Background: The escalating prevalence of adrenal incidentaloma (AI) has been associated with the improvement of radiologic techniques and widespread imaging in aging population. It is currently unclear whether patients with obesity more likely develop AI and the current rise in the prevalence of AI could be at least partly associated with the respective rise in obesity. We compared the prevalence and characteristics of non-functional (NF) and autonomous cortisol secreting (ACS) adrenal incidentalomas (AIs) after the study population was stratified by different body mass indexes (BMI) and age groups. Methods: Retrospective cross-sectional study comprising of 432 patients (40.6% male, 59.4% female) with NFAI (N = 290) and ACS (N = 142), of median age 63.4 (54.0-71.6) years and median BMI 28.6 (25.5-31.7) kg/m 2. The data collection contained 11.132 points including demographic, anthropometric, radiologic, hormonal and metabolic parameters. Results: We observed 68-87% higher prevalence of AI across different age groups in NFAI and ACS in obese/ overweight compared to normal weight subjects. Patients with ACS were older (P = 0.008), with higher basal cortisol (P < 0.001), lower basal DHEAS (P = 0.001), lower suppression DHEAS (P = 0.027) and higher aldosterone (P = 0.039). AIs with ACS were larger than NFAI (P < 0.001). Interestingly, ACS group had lower body mass (P = 0.023) and did not differ in BMI, blood pressure, heart rate, lipid profile, fasting glucose and presence of diabetes mellitus type 2 when compared to NFAI., By contrast to the similarity of metabolic profiles in ACS and NFAI, some components of adverse metabolic traits were rather associated with higher BMI and older age, in particular in NFAI.
Most data on natural history of nonfunctioning adrenal incidentalomas (NFAI) are provided by follow-ups up to 5 years. We conducted a 10.5 (9.1-11.9)-year follow-up study of NFAI in 67 participants (20 (29.9%) males, 47 (70.1%) females) of mean age 57.9 (52.3-63.9) years and BMI 27.42 (24.07-30.56) kg/m2). We also evaluated the associations between baseline body mass index (BMI) and changes of NFAIs’ characteristics at follow-up. Progression to mild autonomous cortisol excess (MACE) was observed in 15 (22 %) patients, with 14 of them having post overnight dexamethasone suppression test (ODST) cortisol between 50-138 nmol/L and only one >138 nmol/L. The progression rate was significantly higher in overweight and obese than in normal weighted subjects. Patients that developed MACE had significantly higher baseline mean cortisol after 1 mg ODST. Tumor enlargement ≥10 mm occurred in 8.9% of patients. All tumors had persistent radiological characteristics typical for adrenal adenoma. In comparison with reports of shorter observational periods, we observed higher growth rate ≥10 mm and higher progression rate from NFAI to MACE, particularly in overweight and obese subjects. We concluded that duration of the follow-up period is an important factor in characterizing the natural history of NFAI. Higher baseline BMI and higher baseline cortisol after ODST might predict the long-term likelihood of progression in hormonal activity. The magnitudes of observed progressions in growth or hormonal activity were clinical insignificant. Our long-term follow-up therefore clearly supports the general view that long term monitoring of patients with NFAI is not necessary.
A fracture in the thoracolumbal junction may cause complete or incomplete damage to the spinal cord, conus medullaris or cauda equina and result in an isolated or mixed lesion of the upper and lower motor neurons causing leg weakness and urinary/bowel/sexual dysfunction. In this retrospective cross-sectional study, we aimed to describe electrodiagnostic and urodynamic findings after thoracolumbal fractures and determine potential discriminating factors. We identified 74 cases (mean age 42 years, range 16–79 years, 55 men) admitted to our institution between 2008 and 2018 for Th12, L1 or L2 vertebral fractures, and retrieved from their medical records available demographic, clinical, electrodiagnostic and urodynamic data. The most common electrodiagnostic findings in the lower limbs (n = 40) were moderate-to-severe L3–S1 (35%) and L5–S1 (40%) lesions. As to the external anal sphincter (n = 33), the most frequent findings were an incomplete cauda equina (39%) or conus medullaris (15%) lesion, followed by the combined upper and lower motor neuron lesion (12%). Only the fracture level (with peripheral damage) was statistically significantly associated with electromyography findings. Detrusor overactivity or underactivity was each present in 37 (50%) cases. Those with Th12 versus L1–L2 fractures had higher odds of exhibiting detrusor overactivity; men had higher odds of using clean intermittent catheterization for bladder emptying than women. In summary, detrusor overactivity is common after fractures at the thoracolumbal junction and urodynamic findings are essential for proper diagnosis and selection of therapeutic approach. Combining urodynamic and electrodiagnostic studies is especially valuable in the presence of L1 fracture and lower urinary tract symptoms.
