RESUMO

This review focuses on primary amenorrhea and primary/premature ovarian insufficiency due to hypergonadotropic hypogonadism. Following a thoughtful, thorough evaluation, a diagnosis can usually be discerned. Pubertal induction and ongoing estrogen replacement therapy are often necessary. Shared decision-making involving the patient, family, and health-care team can empower the young person and family to successfully thrive with these chronic conditions.

RESUMO

BACKGROUND: Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is an endemic chronic disease which is characterized with progressive depletion of CD4 T cells and increased susceptibility to opportunistic infections. Previous studies have associated HIV infection with increased hypogonadism. However, the prevalence of hypogonadism remained poorly defined and widely ranging in various studies. This study aims to evaluate the serum gonadal hormonal levels and hypogonadism in antiretroviral therapy (ART) naïve newly diagnosed HIV infected-males in Mwanza, Tanzania. METHODS: This was a comparison study involving 81 ART naïve newly diagnosed HIV-infected adult males as study group and 81 apparently healthy HIV-negative males as comparison group. The participants in the study group and comparison group were matched by body mass index and age. Serum hormones [Total testosterone (TT), follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E) were estimated. Serum testosterone < 300 ng/dl, or testosterone > 300 ng/dl with high LH and FSH (compensatory hypogonadism) were taken as markers of hypogonadism. Data were analyzed using STATA version 15. RESULTS: The median serum testosterone level among ART naïve newly diagnosed HIV-infected adult males was significantly lower as compared to their comparison group (447 [259-534] versus 517 [396-605]; p = 0.0074) and shown to decrease with decreasing CD4 level. The median [IQR] serum FSH level among ART naïve newly diagnosed HIV-infected adult males was significantly higher than among their comparison group (3.8 [2.1-6.5] versus 2.6 [1.8-4.2]; p = 0.0086). The differences in serum LH and Estradiol were not statistically significant. Furthermore, the proportion of hypogonadism was significantly higher among ART naïve newly diagnosed HIV-infected adult males than in their comparison group (37.0% [30/81] versus 14.8% [12/81]; p = 0.0006). Out of these 30, 24 HIV-infected males had secondary hypogonadism, one had primary, and the remaining five had compensatory hypogonadism. CONCLUSION: Serum testosterone was lower and follicle stimulating hormone was higher among ART naïve HIV-infected males as compared to the HIV negative controls. Hypogonadism, mainly secondary, is common endocrine abnormality among ART naïve HIV-infected male patients in this study. HIV is associated with variations in gonadal hormones which may lead to sexual dysfunction in infected individuals.

RESUMO

Managing patients unable to produce sex steroids using gonadotropins to mimic minipuberty in hypogonadotropic hypogonadism, or sex steroids in patients with Klinefelter or Turner syndrome, is promising. There is a need to pursue research in this area, with large prospective cohorts and long-term data before these treatments can be routinely considered.

RESUMO

OBJECTIVE: Childhood cancer survivors are at risk for hypogonadism. The impact of hypogonadism on neurocognitive impairment and emotional distress in the non-cancer population has been shown; however, the relationship among the childhood cancer survivor population is unknown. We aimed to evaluate the contribution of hypogonadism to neurocognitive impairment and emotional distress among survivors. DESIGN: Cross-sectional study using retrospective cohort. METHODS: In total, 3628 survivors who completed standard neurocognitive tests (six domains: processing speed, memory, executive function, attention, academics, and global cognition) and self-reported emotional distress were included in our study. Participants were stratified by sex and gonadal status. Outcomes were compared between hypogonadal and eugonadal groups by multivariable analysis, adjusting for established predictors, and mediation analyses to determine the direct/indirect effects of hypogonadism on outcomes. RESULTS: The hypogonadal group exhibited a higher prevalence of neurocognitive impairment across domains, but no difference in emotional distress. Hypogonadal females exhibited higher relative risk (1.7, 95% CI, 1.2-2.5) for impaired visual processing speed, compared to eugonadal females after adjusting for cancer-related variables. In mediation models, hypogonadism had a significant direct (P < .01) and indirect (from P < .01) impact on impairment in visual processing speed among females. Males demonstrated direct (P = .03) and indirect (P = .04) impact of hypogonadism on motor processing speed. CONCLUSION: Processing speed may be the most vulnerable neurocognitive domain associated with hypogonadism in survivors, while other domains were mainly impacted by cancer-related variables. Our findings support the need for further evaluation of the impact of sex hormone replacement therapy on neurocognitive function.

RESUMO

PURPOSE: Kallmann syndrome is a rare disease characterized by delayed puberty, infertility and anosmia. We report the clinical and genetic characteristics of three patients with Kallmann syndrome who presented with Klinefelter syndrome and defined this neglected combined form of hypogonadism as mixed hypogonadism. METHODS: Clinical data and examinations were obtained, including laboratory examination and magnetic resonance imagination (MRI) of the olfactory structures. Congenital hypogonadotropic hypogonadism (CHH) related genes were screened by next generation sequencing (NGS). RESULTS: Three patients with Kallmann syndrome were included. They had co-existence with Klinefelter syndrome and showed hypogonadotropic hypogonadism. Patient 1 was complicated with germinoma. CONCLUSION: Mixed hypogonadism was defined as hypogonadotropic hypogonadism in Klinefelter syndrome or primary testicular disease. Clinicians should be alert to mixed hypogonadism when spermatogenesis induction failed in patients with CHH or gonadotropin levels decrease in patients with Klinefelter syndrome.

RESUMO

Obesity-related hypogonadotropic hypogonadism is a well-characterized condition in men (termed male obesity-related secondary hypogonadism; MOSH); however, an equivalent condition has not been as clearly described in women. The prevalence of polycystic ovary syndrome (PCOS) is known to increase with obesity, but PCOS is more typically characterized by increased gonadotropin-releasing hormone (GnRH) (and by proxy luteinizing hormone; LH) pulsatility, rather than by the reduced gonadotropin levels observed in MOSH. Notably, LH levels and LH pulse amplitude are reduced with obesity, both in women with and without PCOS, suggesting that an obesity-related secondary hypogonadism may also exist in women akin to MOSH in men. Herein, we examine the evidence for the existence of a putative non-PCOS "female obesity-related secondary hypogonadism" (FOSH). We précis possible underlying mechanisms for the occurrence of hypogonadism in this context and consider how such mechanisms differ from MOSH in men, and from PCOS in women without obesity. In this review, we consider relevant etiological factors that are altered in obesity and that could impact on GnRH pulsatility to ascertain whether they could contribute to obesity-related secondary hypogonadism including: anti-Müllerian hormone, androgen, insulin, fatty acid, adiponectin, and leptin. More precise phenotyping of hypogonadism in women with obesity could provide further validation for non-PCOS FOSH and preface the ability to define/investigate such a condition.

RESUMO

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 can affect the hypothalamic-pituitary-gonadal axis (HPG) due to the expression of the angiotensin-converting enzyme 2 receptor. OBJECTIVES: To assess the prevalence of hypogonadism and Sertoli cell dysfunction in coronavirus disease 2019 (COVID-19) male survivors. METHOD: Male subjects recovered from acute COVID-19 infection were prospectively observed. The primary outcomes included the proportion of hypogonadism, defined biochemically as serum testosterone<230 ng/dL or CFT of<6.4 ng/mL if the total testosterone is between 230-320 ng/m. Sertoli cell dysfunction was defined as inhibin-B level<54.5 pg/mL. Subjects with hypogonadism were followed up at 12 months to assess the recovery of the HPG axis. RESULTS: Eighty-three subjects aged≥18 years were evaluated at a median of 120 (±35) days post-recovery. Their mean age was 49.50±12.73 years, and the mean BMI was 26.84±5.62 kg/m2. Low testosterone was detected in 21 (24.71%) and low inhibin-B was detected in 14 (19.71%) out of 71 subjects at 3 months. Subjects with low testosterone were younger, with a mean age of 43.29±12.03 years (P-0.08) and higher BMI (P-0.012). The severity of COVID-19 infection, duration of hospitalization, and other factors were not significantly associated with low testosterone. At 12 months, 18 out of 21 subjects came for follow-up, of which 9 (50%) showed persistently low testosterone, suggestive of hypogonadism. CONCLUSION: Following COVID-19 infection, testosterone levels recovered over time; however, a significant proportion of subjects had low levels at 12-month follow-up. These findings have long-term implications for the management of COVID-19 subjects.

RESUMO

Introduction: Impaired testosterone secretion is a frequent sequela following hematopoietic stem cell transplantation (HSCT) in pediatrics, but long-term longitudinal trendlines of clinical and biochemical findings are still scanty. Methods: Monocentric, retrospective analysis. Male patients transplanted <18 years between 1992 and 2021, surviving ≥2 years after HSCT and showing, upon enrollment, clinical and biochemical signs consistent with pubertal onset and progression were included. Clinical and biochemical data collected every 6-12 months were recorded. Results: Of 130 patients enrolled, 56% were prepubertal, while 44% were peri-/postpubertal upon HSCT. Overall, 44% showed spontaneous progression into puberty and normal gonadal profile, while the remaining experienced pubertal arrest (1%), isolated increase of FSH (19%), compensated (23%) or overt (13%) hypergonadotropic hypogonadism. Post-pubertal testicular volume (TV) was statistically smaller among patients still pre-pubertal upon HSCT (p 0.049), whereas no differences were recorded in adult testosterone levels. LH and testosterone levels showed a specular trend between 20 and 30 years, as a progressive decrease in sexual steroids was associated with a compensatory increase of the luteinizing hormone. A variable degree of gonadal dysfunction was reported in 85%, 51%, 32% and 0% of patients following total body irradiation- (TBI), busulfan-, cyclophosphamide- and treosulfan-based regimens, respectively. TBI and busulfan cohorts were associated with the lowest probability of gonadal event-free course (p<0.0001), while it achieved 100% following treosulfan. A statistically greater gonadotoxicity was detected after busulfan than treosulfan (p 0.024). Chemo-only regimens were associated with statistically larger TV (p <0.001), higher testosterone (p 0.008) and lower gonadotropin levels (p <0.001) than TBI. Accordingly, the latter was associated with a 2-fold increase in the risk of gonadal failure compared to busulfan (OR 2.34, CI 1.08-8.40), whereas being pre-pubertal upon HSCT was associated with a reduced risk (OR 0.15, CI 0.08-0.30). Conclusions: a) patients pre-pubertal upon HSCT showed a reduced risk of testicular endocrine dysfunction, despite smaller adult TV; b) patients showed downwards trend in testosterone levels after full pubertal attainment, despite a compensatory increase in LH; c) treosulfan was associated to a statistically lower occurrence of hypogonadism than busulfan, with a trend towards larger TV, higher testosterone levels and lower gonadotropins.

RESUMO

OBJECTIVE: To determine the molecular characterisation of beta-thalassemia major patients, pattern of major endocrine complications and its association with haemoglobin subunit beta gene variants. Method: The cross-sectional study was conducted from November 2021 to November 2022 after approval from the ethics review committee of Liaquat University of Medical and Health Sciences, Jamshoro, Pakistan, and comprised of 88 patients with beta thalassemia major aged >8 years and having serum ferritin level >1000 µg/L. The subjects were analysed for haemoglobin subunit beta gene variants and major endocrine complications, like growth retardation, hypogonadism, hypothyroidism, hypoparathyroidism and diabetic abnormalities using an automatic chemistry analyser, fully automatic chemiluminescence immunoassay analyser, enzyme-linked immunosorbent assay and real-time polymerase chain reaction. Data was analysed using SPSS 25. RESULTS: Of the 88 subjects, 40(45.4%) were girls and 48(54.5%) were boys. The overall mean age was 12±2.81 years. Of the total, 55(62.5%) had growth retardation, 41(46.6%) were cases of hypogonadism, 16(18.1%) hypothyroidism, 5(5.7%) hypoparathyroidism, 3(3.4%) diabetes mellitus and 8 (9.1%) had impaired glucose tolerance. Also, 65 (73.9%) patients confronted at least one endocrine complication. Endocrine complications were strongly associated with serum ferritin levels (p=0.000). The most common haemoglobin subunit beta gene variant identified was IVSI-5 (G>C) in 36 (40.9%), and the least identified variant was cluster of differenctiation-CD26(G>A) 1(1.1%). The association between haemoglobin subunit beta gene variants with endocrine complications was statistically non-significant (p>0.05). CONCLUSIONS: IVSI-5 (G>C) was found to be the most frequent haemoglobin subunit beta gene variant among beta- thalassemia major patients.

RESUMO

BACKGROUND: Cranial radiotherapy (CRT) is recommended to high-risk pediatric patients with acute lymphoblastic leukemia or aggressive non-Hodgkin's lymphoma (ALL/NHL). However, effects of CRT treatment on the development of metabolic/endocrine disorders remain unclear. This meta-analysis aimed to identify metabolic and endocrine disturbances in survivors of childhood-onset and CRT-treated ALL/NHL. METHODS: Different online databases were searched using restricted search fields. Follow-up data and outcome measurements, including the prevalence of growth hormone (GH) deficiency, hypothyroidism, vitamin D deficiency, overweight/obesity, and hypogonadism were recorded. The height data was indicated by height-standard deviation score (height-SDS). Statistical estimates such as odds ratio (OR) and weighted standard mean difference (SMD) were compared between additional CRT treatment group and non-CRT treatment group. Study-to-study heterogeneity was calculated by calculating I-squared statistic, and fixed/random effect was applied to synthesize and analyze extracted data. RESULTS: Fifteen studies were included (4269 patients in total). Adult height SDS was lower in CRT-treated patients (pooled SMD = -0.581, 95% CI: -0.649--0.512), and CRT-treated patients were likely to develop short stature (pooled OR = 2.289, 95% CI:1.674-3.130). Regardless of the study year, which potentially reflects the state-of-the-art CRT technique, the prevalence of short stature and GH deficiency was time-independent. Additionally, previous CRT can increase the risk of precocious puberty (pooled OR = 2.937, 95% CI: 1.281-6.736), hypothyroidism (pooled OR = 2.057, 95% CI:1.510-2.801), and hypogonadism (pooled OR = 3.098, 95% CI:2.521-3.807). However, the risk of being overweight/obese was similar between the patients with and without CRT (pooled OR = 1.278, 95% CI: 0.675-2.421). CONCLUSION: Childhood-onset and CRT-treated ALL/NHL survivors are likely to have shorter height, precocious puberty, hypothyroidism, and hypogonadism.

RESUMO

BACKGROUND AND AIM: Hypogonadism and abnormalities of glucose homeostasis, resulting from iron-induced pituitary and pancreatic ß-cell dysfunction respectively, are the most frequently reported endocrine abnormalities in patients with ß-thalassemia major (ß-TM), also identified as transfusion-dependent thalassemia (TDT). STUDY DESIGN AND PATIENTS: The aim of the present retrospective study was to evaluate the long-term effects of hormone replacement therapy (HRT) on glucose metabolism and insulin secretion/sensitivity during 3-h oral glucose tolerance test (OGTT) in adolescent and young ß-TM women with acquired hypogonadototropic -hypogonadism (AHH).Twelve hypogonadal ß-TM females with AHH on HRT were followed for 8.26 ± 1.49 years. RESULTS: At baseline, 10 patients (83.3%) had normal OGTT, 1 patient presented with impaired glucose tolerance (IGT) and 1 patient had an isolated PG level of 165 mg/dL at 1-h during OGTT (H-NGT). At last evaluation, 7 patients (58.4 %) had normal OGTT, while 5 patients (41.6%) had abnormal OGTT. Reduced insulin sensitivity and impaired first-phase insulin secretion were also documented. Three of 4 ß-TM patients on treatment with estradiol hemihydrate MX 50 patches plus oral medroxyprogesterone acetate (MPA), associated with a very effective iron chelation therapy, maintained normal glucose tolerance from baseline to last evaluation. Significant adverse events due to HRT or additional endocrine complications were not documented in any cases during the follow-up. CONCLUSION: Deterioration of glycemia (dysglycemia) occurred in 45.4% (5/11) of thalassemic females on long-term HRT. Additional studies are needed to elucidate the validity of our preliminary observations.

RESUMO

OBJECTIVE: Assessment of the efficacy and safety/tolerability of the aromatase inhibitor leflutrozole to normalise testosterone in Obesity-associated Hypogonadotropic Hypogonadism (OHH). DESIGN: Placebo-controlled, double-blind, RCT, in 70 sites in Europe/USA. METHODS: Patient inclusion criteria: men with BMI of 30-50 kg/m2, morning total testosterone (TT) < 10.41 nmol/L, and two androgen deficiency symptoms (at least one of sexual dysfunction). Patients randomised to weekly leflutrozole (0.1/0.3/1.0 mg) or placebo for 24 weeks. Primary endpoint: normalisation of TT levels in ≥75% of patients after 24 weeks. Secondary endpoints (included): time to TT normalisation and change in LH/FSH. Safety was assessed through adverse events and laboratory monitoring. RESULTS AND CONCLUSIONS: Of 2103 screened, 271 were randomised, 81 discontinued. Demographic characteristics were similar across groups. Mean BMI was 38.1 kg/m2 and TT 7.97 nmol/L. The primary endpoint was achieved in all leflutrozole-treated groups by 24 weeks with a dose-tiered response; mean TT 15.89; 17.78; 20.35 nmol/L, for leflutrozole 0.1 mg, 0.3 mg, and 1.0 mg groups respectively, vs 8.04 nmol/L for placebo. LH/FSH significantly increased in leflutrozole vs placebo groups. No improvements in body composition or sexual dysfunction were observed. Semen volume/total motile sperm count improved with leflutrozole vs placebo. Treatment-emergent adverse events, more common in leflutrozole-treated groups included, raised haematocrit, hypertension, increased PSA, and headache. Some reduction in lumbar bone density was observed with leflutrozole (mean -1.24%, -1.30%, -2.09%) and 0.66% for 0.1 mg, 0.3 mg, 1.0 mg, and placebo, respectively, without change at the hip. This RCT of leflutrozole in OHH demonstrated normalisation of TT in obese men. FSH/LH and semen parameter changes support that leflutrozole may preserve/improve testicular function. CLINICAL TRIAL REGISTRATION NUMBER: NCT02730169.

RESUMO

BACKGROUND: Hypogonadism is a significant late complication in childhood cancer survivors (CCS). The aim of this study was to elucidate the advantages and limitations of estrogen replacement therapy (ERT) for CCS with hypogonadism. METHODS: Seventeen CCS were divided into two groups: gonadal hypogonadism (GH) group (n = 8) and central hypogonadism (CH) group (n = 9). Pearson correlation coefficients were used to investigate the impact of cancer management on final height, bone density, and uterine development. RESULTS: Seven of GH group had hematologic malignancies, and all of them underwent total body irradiation before bone marrow transplantation. The GH group showed significant positive correlations between the onset age of disease treatment and final height (p < 0.05, R = 0.712) and uterine size following ERT (p < 0.05, R = 0.775). All CCS in the CH group had brain tumors, and seven of them received chemotherapy. There were trends towards positive and negative correlations between the onset age of disease treatment and final height (p = 0.09, R = 0.598) or uterine size (p = 0.07, R = - 0.669), respectively. A negative correlation trend was observed between the age at ERT initiation and final height (p = 0.07, R = - 0.769) or bone density (p = 0.18, R = - 0.626) in six CH patients who received growth hormone therapy. Five CCS in both groups experienced osteoporosis, despite receiving ERT. CONCLUSION: Individualized management strategies beyond ERT are essential to reduce long-term complications in CCS with hypogonadism, considering the type and timing of cancer treatment.

RESUMO

OBJECTIVE: To determine if hypogonadism leads to delayed urinary function recovery post-radical prostatectomy (RP) by studying the effect of preoperative factors including age, membranous urethral length, radiation therapy, and Body Mass Index on urinary continence in patients with or without hypogonadism. MATERIALS AND METHODS: We identified 1209 patients treated by RP with both pretreatment T and post-treatment urinary outcome. We assessed whether there was an association between low preoperative T level (prenoon T ≤ 300 ng/dL) and continence (using ≤1 pad/d) at 6 and 12months post-RP. Patient-reported continence was used when available, otherwise, surgeon-assessed continence was used. Logistic regression models were used, adjusted for age at RP and nerve-sparing status. RESULTS: Median age at RP was 61 (Intraquatile Range (IQR) 56, 66), 92% of patients had at least one nerve spared and 99% were continent at baseline. Continence in patients with low T was nonsignificantly lower at 6months (odds ratio 0.69, 95% confidence interval 0.44, 1.06; P = .10) and nonsignificantly higher at 12months (odds ratio 1.07, 95% confidence interval 0.71, 1.58; P = .8). Sensitivity analyses excluding patients with preoperative metastasis or treated with androgen deprivation therapy (ADT) and including testosterone as a continuous predictor were consistent with the primary analysis; similarly finding no evidence of an association. CONCLUSION: Although we cannot rule out an effect on early continence, overall the evidence does not suggest that low serum testosterone adversely impacts urinary function recovery after RP. This finding can be used to counsel patients enrolled in neoadjuvant ADT trials or those patients undergoing RP who have had prior ADT, such as in the setting of oligometastatic disease.

RESUMO

Functional hypogonadotropic hypogonadism (FHH) is an increasingly frequent condition, whose pathological mechanisms are not yet fully clarified. The concept of FHH has now completely replaced that of late onset hypogonadism, that only concerned the ageing man. FHH is the result of an impairment of the hypothalamic-pituitary gonadal axis (HPG-A) function, resulting in decreased testosterone concentrations associated with low or inappropriately normal gonadotropin levels and infertility; it can be diagnosed once organic causes of hypogonadism are excluded. The growing occurrence of FHH derives from its association with widespread conditions, such as obesity and diabetes mellitus, but also to the increasing ease and frequency of use of several drugs, such as opioids, glucocorticoids, and sex steroids. Moreover, given the tendency of many subjects to excessive physical activity and drastic reduction in caloric intake, FHH may also be secondary to low energy availability. Finally, the association with HIV infection should not be overlooked. Therefore, there is an important variability in the diseases that can lead to FHH. Despite the heterogeneity of the underlying pathologies, the mechanisms leading to FHH would seem quite similar, with the initial event represented by the impairment at the HPG-A level. Nevertheless, many different biological pathways are involved in the pathogenesis of FHH, therefore the aim of the current paper is to provide an overview of the main relevant mechanisms, through a detailed analysis of the literature, focusing specifically on pathogenesis and clinical, diagnostic and therapeutic aspects.

RESUMO

PURPOSE: Hypogonadism is associated with a wide range of physical and psychological symptoms that can affect the overall health of men. However, in a developing country, there are several imposing challenges in the diagnosis and treatment of hypogonadism, including a lack of awareness and understanding of the condition among healthcare providers and patients, limited resources and the high cost of treatment. This review aimed to examine the potential benefits and risks of testosterone replacement therapy (TRT) and provides a perspective of a developing country on the topic. MATERIALS AND METHODS: A comprehensive literature review was conducted to gather relevant information on the impact of testosterone deficiency on ageing males and the effectiveness of TRT for treating hypogonadism. Published peer-reviewed articles were analyzed to evaluate the benefits and risks of TRT. Additionally, the unique challenges faced in the diagnosis and treatment of hypogonadism in a developing country were considered. RESULTS: Testosterone replacement therapy has been shown to be an effective treatment for hypogonadism, particularly in symptomatic men with low testosterone levels. It offers potential benefits such as improvements in symptoms and overall quality of life. However, there are associated risks and side effects that need to be considered. In a developing country, challenges such as limited awareness and understanding of hypogonadism, resource constraints, and high treatment costs pose additional barriers to accessing TRT and comprehensive care. CONCLUSION: In conclusion, TRT holds promise as a treatment for hypogonadism, but its implementation and accessibility face significant challenges in a developing country. Addressing these challenges, including raising awareness, allocating resources, and finding cost-effective solutions, is crucial for ensuring that men with hypogonadism in such settings receive appropriate diagnosis and treatment. Further research and efforts are needed to improve the management of hypogonadism in developing countries and optimize the potential benefits of TRT for affected individuals.

RESUMO

BACKGROUND AND AIMS: The impact of utilizing both symptoms as well as biochemically confirmed androgen deficiency in diagnosis of hypogonadism among type 2 diabetic men is relatively less studied. Furthermore, various determinants of hypogonadism in these men especially the role of insulin resistance and hypogonadism were studied. METHODS: This is a cross sectional study of 353 T2DM men aged 20-70 years of age. Hypogonadism was defined by taking both symptoms as well as calculated testosterone levels. Symptoms were defined using androgen deficiency in ageing male (ADAM) criteria. Various metabolic and clinical parameters were assessed and evaluated with regards to presence or absence of hypogonadism. RESULTS: Among 353 patients, 60 had both symptoms as well as biochemical evidence of hypogonadism. Assessment of calculated free testosterone but not total testosterone identified all such patients. Body mass index, HbA1c, fasting triglyceride level and HOMA IR inversely correlated with calculated free testosterone. We found that insulin resistance (HOMA IR) was independently associated with hypogonadism (odds ratio=1.108). CONCLUSION: Assessment of both symptoms of hypogonadism and calculated free testosterone represents a better way for correct identification of hypogonadal diabetic men. Insulin resistance has a strong association with hypogonadism independent of obesity and complication status of diabetes.

RESUMO

Testosterone plays a key role in the maintenance of physical and mental functions in men. Age-related testosterone decline is closely associated with sarcopenia and muscle deterioration, while testosterone decline is linked with the etiology and prevention of diseases such as angina pectoris, arteriosclerosis, obesity, metabolic syndrome, and dementia. Late-onset hypogonadism (LOH) is defined as a disease characterized by age-related testosterone decline and associated clinical symptoms. Testosterone replacement therapy improves health-related QOL in patients with LOH.

RESUMO

In humans, post-traumatic hypopituitarism (PTHP) is a common complication of traumatic brain injury, with the most frequently reported hormonal deficiencies resulting in hyposomatotropism and hypogonadism, followed by hypothyroidism, hypocortisolism, and central diabetes insipidus. To date, PTHP has rarely been reported in cats, and the reported cases often describe a single hormone deficiency. This report details an approximately 7-month-old cat with a history of suspected traumatic brain injury at 5 wk of age, that presented with growth retardation (1.53 kg) and polyuria-polydipsia. Thyroid panel, thyrotropin-releasing hormone stimulation test, thyroid scan with Technetium-99, repeat measurement of serum IGF-1, resting cortisol, endogenous ACTH concentration, and ACTH stimulation testing were performed. The cat was diagnosed with presumptive PTHP leading to hyposomatotropism, hypothyroidism, central diabetes insipidus, and hypogonadism. In this case, treatment of the hypothyroidism and central diabetes insipidus were successful. Hyposomatotropism and hypogonadism were not treated. Although reported feline PTHP cases have described a single hormone deficiency, this report details a cat with presumptive PTHP leading to hyposomatotropism, hypothyroidism, central diabetes insipidus, and hypogonadism. Attention should be paid to the potential for the development of PTHP in cats secondary to traumatic brain injury. Key clinical message: Post-traumatic hypopituitarism in cats can lead to multiple hormone deficiencies, leading to hyposomatotropism, hypothyroidism, central diabetes insipidus, and hypogonadism.


Insuffisances hormonales hypophysaires multiples chez un chaton : hyposomatotropisme, hypothyroïdie, diabète insipide central et hypogonadisme. En médecine humaine, l'hypopituitarisme post-traumatisme crânien (HPPT) est une complication fréquente après un trauma crânien. Les insuffisances hormonales les plus fréquemment rapportées sont l'hyposomatotropisme et l'hypogonadisme, suivis de l'hypothyroïdie, de l'hypocortisolisme et du diabète insipide central. À ce jour, l'HPPT a rarement été décrit chez le chat, et les cas publiés décrivent bien souvent une déficience hormonale unique. Dans le cas présent, un chat âgé d'environ 7 mois, avec un antécédent de trauma crânien suspecté à l'âge de 5 semaines, a été présenté avec un retard de croissance (1,53 kg) et un syndrome polyurie-polydipsique. Les examens d'endocrinologie complémentaires incluaient le dosage des hormones thyroïdiennes, la stimulation de l'hypophyse par la thyrolibérine, une scintigraphie thyroïdienne (Technetium-99), le dosage de l'IGF-1, du cortisol basal, de la concentration d'ACTH endogène, et un test de stimulation à l'ACTH. Le chat a été diagnostiqué de manière présomptive avec un HPPT causant de multiples insuffisances hormonales hypophysaires : hyposomatotropisme, hypothyroïdie, diabète insipide central et hypogonadisme. Chez ce chat, le traitement de l'hypothyroïdie et du diabète insipide central a été réussi. L'hyposomatotropisme et l'hypogonadisme n'ont pas été traités. Alors que les rapports de cas publiés sur l'HPPT félin décrivent souvent une seule déficience hormonale, ce chat a été diagnostiqué avec de multiples insuffisances hormonales hypophysaires. Les cliniciens doivent rester attentifs au développement potentiel d'un hypopituitarisme après un trauma crânien.Message clinique clé :L'hypopituitarisme post-traumatique chez le chat peut entraîner de multiples déficiences hormonales, entraînant un hyposomatotropisme, une hypothyroïdie, un diabète insipide central et un hypogonadisme.(Traduit par les auteurs).
