Abstract
CONTEXT There are concerns about the long-term safety of conventional therapy on renal health in patients with hypoparathyroidism. Careful audit of these would help comparisons with upcoming parathyroid hormone therapy. OBJECTIVE We investigated nephrocalcinosis, renal dysfunction, and calculi, their predictors and progression over long-term follow-up in patients with primary hypoparathyroidism (PH). DESIGN AND SETTING An observational study at a tertiary care center was conducted. PARTICIPANTS AND METHODS A total of 165 PH patients receiving conventional therapy were evaluated by radiographs, ultrasonography, and computed tomography. Their glomerular filtration rate (GFR) was measured by Tc-99m-diethylenetriamine penta-acetic acid clearance. Clinical characteristics, serum total calcium, phosphorus, creatinine, hypercalciuria, and fractional excretion of phosphorus (FEPh) at presentation and during follow-up were analyzed as possible predictors of renal complications. Controls were 165 apparently healthy individuals. RESULTS Nephrocalcinosis was present in 6.7% of PH patients but not in controls. Patients younger than 15 years at presentation and with higher serum calcium-phosphorus product were at higher risk. Nephrocalcinosis showed no significant association with cataract and intracranial calcification. Prevalence of renal calculi was comparable between hypoparathyroid patients and controls (5% vs 3.6%, P = .58). Fourteen percent of patients had a GFR less than 60 mL/min/1.73 m2. Increased FEPh during follow-up was the significant predictor of low GFR. Nephrocalcinosis developed in 9% of patients over 10 years of conventional therapy. CONCLUSION A total of 6.7% of PH patients had nephrocalcinosis, and 14% showed renal dysfunction. Prevalence of renal calculi was similar in patients and controls. Nine percent of patients developed nephrocalcinosis over 10 years of conventional therapy.

Abstract
BACKGROUND The advent of techniques for the assessment of iron overload (liver T2*-MRI) has led to the awareness that focal nodular hyperplasia (FNH) represents a possible incidental finding after hematopoietic stem cell transplantation (HSCT), though its pathogenesis is still unclear. METHODS We performed a retrospective analysis of the liver T2*-MRI scans performed between 2013 and 2018 in a single pediatric HSCT Unit and recorded the number of patients with FNH (group A). Patients incidentally diagnosed with FNH at imaging performed for different clinical indications were included in group B. RESULTS Nine of 105 (8.6%) patients from group A were diagnosed with FNH. Group B included three patients. Overall, 12 patients were diagnosed 4.4 ± 3.1 years after HSCT. At univariate analysis, female gender (odds ratio [OR] 3.77, P = .03), moderate-to-severe iron overload (OR 6.97, P = .01), and hormone replacement therapy (HRT) administered for at least 6 months (OR 18.20, P = .0002) exposed patients to a higher risk of developing FNH. The detrimental effect of HRT was significant also at multivariate analysis (OR 7.93, P = .024). MRI-T2* values in affected patients were statistically lower than healthy controls (P < .001). CONCLUSIONS We confirm the high incidence of FNH among transplanted pediatric patients and demonstrate the potential pathogenic role of HRT and iron overload.

Abstract
OBJECTIVE To determine the effect of hormone therapy (HT) use on pelvic organ support. METHODS A retrospective observational study involving postmenopausal women with pelvic floor dysfunction attending a tertiary urogynecology center between January 2012 and March 2015. All underwent a clinical examination including International Continence Society Pelvic Organ Prolapse Quantification and 4D translabial ultrasound imaging. Information on current or former use of systemic HT and current local estrogen use was collected. Main outcome measure was pelvic organ support. RESULTS One thousand four hundred forty-three women were seen during the study period. On univariate analysis, current HT was significantly associated with sonographically determined descent of the rectal ampulla (β [95% confidence interval] 3.4 mm [0.4-6.5], P = 0.03) and Gh + Pb (-0.45 mm [-0.8 to -0.1], P = 0.005). Past HT use, duration of HT use, or current vaginal estrogen use was not associated with pelvic organ support. On multivariate analysis controlling for age, parity, body mass index, history of forceps delivery, and avulsion, the association between current HT on the one hand and Gh + Pb as well as increased descent of the rectal ampulla on ultrasound, remained significant (P = 0.008 and P = 0.012, respectively). CONCLUSION HT may have a minor negative effect on pelvic organ support; however, the effect is likely too small to be clinically relevant.

Abstract
We aimed to evaluate the long-term safety and effectiveness of growth hormone (GH) therapy in Japanese patients with adult growth hormone deficiency (AGHD). In this observational, multicenter study, Norditropin® (Novo Nordisk A/S, Bagsvaerd, Denmark) was administered as injections of 0.021 mg/kg/week as a starting dose divided into 6-7 doses/week. The dose was increased according to clinical response. Patients' data were obtained from medical records. Measurements (lipids, glucose metabolism, and body composition) taken at baseline; 3, 6, and 12 months; and yearly until the end of the study were collected. Adverse drug reactions (ADRs), serious ADRs, and serious adverse events (SAEs) were evaluated. Of 387 registered patients, 334 were eligible for safety. After GH treatment initiation, a marked decrease in total cholesterol was observed earlier in the child-onset group than in the adult-onset group. LDL-cholesterol also decreased, but no significant differences in changes in LDL-cholesterol between adult-onset and child-onset groups were found. A significant increase in HDL-cholesterol starting 1 year after GH treatment initiation was found in the adult-onset group. There was no effect of GH treatment on glucose metabolism. Because of the small number of dual-energy X-ray absorptiometry data, the overall assessment of changes of body composition was difficult. Fifty-six (16.8%), 12 (3.6%), and 35 (10.5%) patients experienced ADRs, serious ADRs, and SAEs, respectively. This study demonstrated a favorable long-term safety and effectiveness profile of GH therapy in AGHD patients in the real-life Japanese clinical practice setting.

Abstract
PURPOSE Management of late onset hypogonadism (LOH) is not homogenous. The aim of the study is to observe the management of patients with low testosterone (T) in highly specialized Italian centres. METHODS The SIAMO-NOI is an observational longitudinal disease registry for the evaluation of the clinical management of patients with low T levels (total T < 12 nmol/L, calculated free T < 225 pmol/l or already in treatment) in 15 Italian centers members of the Italian Society for Andrology and Sexual Medicine (SIAMS). Clinical and biochemical data were collected for four visits during 12 months of observation. RESULTS 432 patients (mean age 50.9 ± 14.9 years) were enrolled. Of them, 247 men were receiving androgen therapy, whereas 145 were naive. After the first visit (V0), 80 men started androgen therapy, whereas 55 remained untreated during the entire observation. Younger age [odds ratio (OR) 0.57 (0.35-0.92)], total T < 8 nmol/l [OR 4.69 (1.59-13.81)], complaining at least one sexual symptom [OR 11.55 (2.01-66.35)] and reporting more severe lower urinary tract symptoms [OR 1.27 (1.01-1.60)] predicted starting an androgen therapy. Sixty-four men started therapy immediately after V0 and maintained it until the observation end. When compared to V0, they reported an increase in all the domains of the International Index of Erectile Function-15 (IIEF-15), in the sexual and physical subdomains of the Aging Male Scale as well as in the International Prostate Symptom Score. Conversely, the untreated group reported a significant improvement, although lower than the treated group, only in the erectile function domain of the IIEF-15. CONCLUSIONS Management of LOH in SIAMS centres is in line with the international guidelines and the newest knowledge about the role of T on prostate health. Androgen therapy is associated with an improvement in all the aspects of sexual life and in the perception of physical strength.

Abstract
Subnormal levels of testosterone are associated with significant negative health consequences, with higher risks of all-cause and cardiovascular mortality. The numbers of studies reporting on the benefits of normalisation of testosterone is increasing but longer-term data on (elderly) men receiving testosterone treatment are almost nonexistent. In this single-centre, cumulative, prospective, registry study, 115 hypogonadal men (mean age 59.05 years) received injections with testosterone undecanoate in 12-week intervals for up to 10 years. Waist circumference, body weight and mean BMI dropped progressively with statistical significance versus previous year for 7 years and, respectively, 8 years for weight and body mass index. Similarly, fasting glucose displayed a significant decrease after the first year continuing to decrease thereafter. A decline in HbA1c , from 6.4% to 5.6% (mean <6%), was observed from year 2 on, together with a decrease in the ratio of triglycerides:high-density lipoprotein (HDL), a surrogate marker of insulin resistance, with an increase in HDL levels. The total cholesterol:HDL ratio and non-HDL cholesterol declined significantly. A decrease was also observed in systolic and diastolic blood pressure, with a decrease in levels of the inflammation marker C-reactive protein. No major adverse cardiovascular events were observed throughout the study.

Abstract
BACKGROUND Concern and controversy characterize nowadays the use of hormone therapy for management of patients with menopausal complaints. This observational non-interventional study examined the use of a marketed oral formulation containing 1 mg estradiol valerate and 2 mg dienogest for treatment of menopausal symptoms in 1292 women visiting 243 gynecological practices in Germany. METHODS Score changes in the Menopausal Rating Scale (MRS) after three and six 28-day cycles were primary endpoints. Subjective reports on skin- and hair-related complaints and satisfaction with treatment effects were assessed. The incidence of adverse drug reactions (ADRs), adverse events (AEs) and vaginal bleeding was evaluated. RESULTS MRS total score decreased substantially and stronger than the clinically relevant change of 5 points (p < 0.0001) as compared with baseline. Subjective skin- and hair-related complaints declined. No unexpected ADRs were reported. AEs (including ADRs) were registered in 8.8% of the participants; most frequent AEs/ADRs were postmenopausal hemorrhage (2.9%) and drug ineffective (1.4%). Nearly 76% of the subjects remained amenorrheic. Approximately 90% of the patients rated the medication's effectiveness/tolerability as good/very good; 84% intended to continue the treatment. CONCLUSION This low-dose estradiol/dienogest formulation proved efficient and well-tolerated option for the alleviation of menopausal symptoms associated with estrogen deficiency.

Abstract
BACKGROUND Experimental studies suggest protective effects of vitamin D on breast carcinogenesis, particularly on estrogen receptor-positive tumors. Epidemiologic data are less conclusive. OBJECTIVE Our objective was to investigate the association between postmenopausal breast cancer risk and current or past vitamin D supplementation overall and according to the use of menopausal hormone therapy (MHT). DESIGN Between 1995 and 2008, 2482 invasive breast cancer cases were diagnosed among 57,403 postmenopausal women from the E3N prospective cohort during 581,085 person-years. Vitamin D supplementation was assessed from biennially self-administered questionnaires sent in 1995, 2000, 2002, and 2005 and from medico-administrative data on drug reimbursements since 2004. Multivariable HRs for primary invasive breast cancer and 95% CIs were estimated by using Cox models. RESULTS A decreased postmenopausal breast cancer risk was associated with current (HR: 0.82; 95% CI: 0.69, 0.97) but not past (HR: 1.10; 95% CI: 0.92, 1.31) vitamin D supplementation (P-homogeneity = 0.02). The association with current vitamin D supplementation differed according to MHT use: ever users (HR: 0.74; 95% CI: 0.60, 0.90) and never users (HR: 1.13; 95% CI: 0.89, 1.56); P-homogeneity = 0.02. CONCLUSIONS In this observational study, current vitamin D supplementation, mostly taken daily and combined with calcium, was associated with a decreased postmenopausal breast cancer risk in MHT users. These findings should be confirmed before considering vitamin D supplementation to partly balance the MHT-associated increased breast cancer risk.

Ten-year change in quality of life in adults on growth hormone replacement for growth hormone deficiency: an analysis of the hypopituitary control and complications study.
Mo, D, Blum, WF, Rosilio, M, Webb, SM, Qi, R, Strasburger, CJ
The Journal of clinical endocrinology and metabolism. 2014;(12):4581-8
Abstract
CONTEXT Previous studies showed improvement in impaired quality of life (QoL) in adult patients with growth hormone (GH) deficiency (GHD) who were treated with GH; improvement was sustained over a few years after GH therapy. OBJECTIVE To evaluate the QoL over 10 years. DESIGN This was a prospective observational study. SETTING The study was conducted in clinical practice. PATIENTS 1436 adult patients with adult-onset (AO) GHD (mean age [standard deviation (SD)]: 49.0 [12.2] years; 49% female) and 96 with childhood-onset (CO) GHD (31.3 [10.0] years; 60% female) (total N = 1532). INTERVENTION GH therapy. MAIN OUTCOME MEASURES QoL was measured by Questions on Life Satisfaction-Hypopituitarism (QLS-H) in countries where validated questionnaires and normative data for calculation of Z-scores were available. Change in QoL was tested by Student's t test and predicted by mixed-model repeated measures (MMRM) analysis. RESULTS At study entry, patients had diminished QoL Z-scores (mean [SD] AO, -1.55 [1.69]; CO -0.98 [1.32]). The largest QoL improvements were in the first year: mean (SD) increase 0.77 (1.37) for AO (P < .001) and 0.50 (1.37) for CO (P < .001). The initial improvement from study entry remained statistically significant throughout 10 years for AO and in years 1 to 4, 6, and 7 for CO (P < .05). MMRM analysis predicted a greater QoL improvement in those who were not depressed, lived in Europe, had poorer Z-scores at entry, had lower body mass index at entry, and had no impaired vision. CONCLUSION These data suggest that GH replacement provides sustained improvement in QLS-H scores toward normality for up to 10 years.
