Objective: The management of visual field damage in patients with macroprolactinomas is a major therapeutic challenge. We aimed to study the visual morbidity associated with macroprolactinoma and its outcomes following medical and surgical treatment. We aimed to identify predictors of visual recovery. Methods: We retrospectively reviewed patient's data including clinical presentation, serial pituitary magnetic resonance imaging, laboratory tests, visual symptoms and neuro‐ophthalmologic examination, visual field tests and optical coherence tomography tests. The main outcome was complete visual field recovery. Descriptive analyses were conducted. Predictors of visual recovery were investigated. Patients: The study cohort included 150 patients with macroprolactinoma [median follow‐up, 6.0 years (interquartile range (IQR) 2.9–10.6)]. Results: At diagnosis, visual field defects were evident in 40 patients (26.7%). At the end of follow‐up, 24 out of 39 available visual field tests (61.5%) exhibited complete recovery. Patients that achieved complete visual recovery had smaller macroadenomas at diagnosis [30.5 mm (15.0–80.0) vs. 42.0 mm (30.0–85.0), p <.01], lower baseline serum prolactin levels [1414 mcg/L (489–3586) vs. 4119 mcg/L (2715–6315), p <.01], lower rates of central hypogonadism (78.3% vs. 93.3%, p =.05) and central hypothyroidism (20.8% vs. 53.3%, p =.04), lower rates of compressive optic neuropathy (35.3% vs. 87.5%, p =.02) and a better visual acuity (better than 6/8 in both eyes, 93.7% vs. 28.6%, p <.01). Conclusions: In our cohort of 150 patients with macroprolactinoma, 40 patients (26.7%) presented with visual field defects, of which 61.5% achieved complete visual recovery with treatment. Patients that achieved complete visual recovery presented with smaller macroadenomas, lower serum prolactin levels, lower rates of central hypogonadism and central hypothyroidism, lower rates of compressive optic neuropathy and better visual acuity.

Hypopituitarism is a rare but significant endocrine disorder characterized by the inadequate secretion of one or more pituitary hormones. The intricate relationship between hypopituitarism and bone health is a topic of growing interest in the medical community. In this review the authors explore associations between hypopituitarism and bone health, with specific examination of the impact of growth hormone deficiency, central hypogonadism, central hypocortisolism, and central hypothyroidism. Pathogenesis, diagnosis, and treatment options as well as challenges posed by osteopenia, osteoporosis, and fractures in hypopituitarism are discussed. [ABSTRACT FROM AUTHOR]

Objective Cancer incidence in patients with endogenous Cushing's syndrome (CS) has never been established. Here, we aimed to assess the cancer risk in patients with CS as compared with individually matched controls. Design A nationwide retrospective matched cohort study of patients with endogenous CS diagnosed between 2000 and 2023 using the database of Clalit Health Services in Israel. Methods Patients with adrenal carcinoma or ectopic CS were excluded. Patients with CS were matched in a 1:5 ratio, with controls individually matched for age, sex, socioeconomic status, and body mass index. The primary outcome was defined as the first diagnosis of any malignancy following a CS diagnosis. Risk of malignancy was calculated using the Cox proportional hazard model, with death as a competing event. Results A total of 609 patients with CS and 3018 controls were included [mean age at diagnosis, 48.0 ± 17.2 years; 2371 (65.4%) women]. The median follow-up was 14.7 years (IQR, 9.9–20.2 years). Patients with CS had an increased cancer risk, with a hazard ratio (HR) of 1.78 (95% CI 1.44–2.20) compared with their matched controls. The risk of malignancy was elevated in patients with Cushing's disease (251 cases and 1246 controls; HR 1.65, 95% CI 1.15–2.36) and in patients with adrenal CS (200 cases and 991 controls; HR 2.36, 95% CI 1.70–3.29). The increased cancer risk in patients with CS persists after exclusion of thyroid malignancies. Conclusion Endogenous CS is associated with increased malignancy risk. These findings underscore the need for further research to establish recommendations for cancer screening in this population. [ABSTRACT FROM AUTHOR]

Background: Men harboring prolactinomas frequently suffer from central hypogonadism with secondary anemia. They present insidious and nonspecific symptoms of hypogonadism, making it difficult to diagnose the disease and determine its duration. The result is a delay in diagnosis, which may have harmful hormonal and metabolic consequences. We hypothesized that a decrease in hemoglobin (HB) levels prior to prolactinoma diagnosis, may signal hyperprolactinemia onset and estimate disease duration. Methods: We retrospectively evaluated the prediagnosis temporal trends in HB levels of 70 males with prolactinoma, diagnosed from January 2010 to July 2022. Men without hypogonadism, patients that received testosterone, and those with unrelated anemia were excluded. Results: Sixty‐one of seventy men (87%) with prolactinoma presented with hypogonadism, and forty men (57%) had HB levels ≤13.5 g/dL at diagnosis. We identified 25 patients with "informative" HB curves (mean age, 46.1±14.9 years; median prolactin, 952 ng/mL; median follow‐up, 14.0 years), demonstrating an obvious prediagnosis HB decrease (greater than 1.0 g/dL), from a prediagnosis baseline HB of 14.4 ± 0.3 to 12.9 ± 0.5 g/dL at diagnosis. The median "low‐HB duration" (from the first low HB measurement to hyperprolactinemia diagnosis) was 6.1 years (IQR, 3.3–8.8 years). In symptomatic patients, we identified a correlation between "low‐HB duration" and patient‐reported sexual dysfunction duration (n = 17, R = 0.502, p = 0.04). The "low‐HB duration" was significantly longer than the reported sexual dysfunction duration (7.0 ± 4.5 vs. 2.9 ± 2.5 years, p = 0.01). Conclusions: In our cohort of men with prolactinomas and hypogonadism, we found a marked decrease in HB levels that preceded prolactinoma diagnosis by a median of 6.1 years, with a mean delay of 4.1 years between HB decrease and hypogonadal symptoms appearance. These results suggest that HB decline prior to prolactinoma diagnosis may serve as a marker for hyperprolactinemia onset in a subset of hypogonadal men and allow a more accurate assessment of disease duration.

Limited data are available regarding the association between pre-admission thyroid-stimulating hormone (TSH) levels and prognosis in hospitalized surgical patients treated for hypothyroidism. We retrospectively evaluated a cohort of 1,451 levothyroxine-treated patients, hospitalized to general surgery wards. The 30-day mortality risk was 2-fold higher for patients with TSH of 5.0–10.0 mIU/L (adjusted OR, 2.3; 95% CI 1.1–5.1), and 3-fold higher for those with TSH > 10.0 mIU/L (3.4; 95% CI 1.3–8.7). Long-term mortality risk was higher in patients with TSH of 5.0–10.0 and above 10.0 mIU/L (adjusted HR, 1.2; 95% CI, 1.0–1.6, and 1.7; 95% CI 1.2–2.4, respectively). We found that in levothyroxine-treated adults hospitalized to surgical wards, increased pre-admission TSH levels are associated with increased short- and long-term mortality. [ABSTRACT FROM AUTHOR]

Background: dopamine agonists are the recommended treatment for male prolactinomas, but some patients may develop dopamine-agonist-resistant hyperprolactinemia, leading to persistent hypogonadism that requires treatment with testosterone. However, testosterone replacement therapy may be associated with a decrease in the efficacy of dopamine agonists due to the aromatization of testosterone to estradiol, which can stimulate the proliferation and hyperplasia of lactotroph cells in the pituitary, inducing resistance to dopamine agonists. Objective: this paper systematically reviewed the role of aromatase inhibitors for men with prolactinoma and dopamine-agonist-resistant or persistent hypogonadism following treatment. Method: we performed a systematic review of all studies (according to PRISMA guidelines), assessing the role of aromatase inhibitors, including anastrozole and letrozole, for male prolactinoma. An English-language search for relevant studies was conducted on PubMed from its inception to 1 December 2022. The reference lists of the relevant studies were also reviewed. Results: our systematic review identified six articles (nine patients), including five case reports and a single case series, on the use of aromatase inhibitors for male prolactinomas. Reducing estrogen levels with an aromatase inhibitor improved sensitivity to dopamine agonists, as the addition of anastrozole or letrozole improves the control of prolactin levels and may lead to the shrinkage of tumors. Conclusion: aromatase inhibitors are of potential value to patients with dopamine-agonist-resistant prolactinoma, or when hypogonadism persists while using high-dose dopamine agonists.

Objective: To study the outcome of men with macroprolactinoma following cabergoline treatment based on tumour size. Design: Retrospective cohort study. Methods: The study included 94 men, divided into three groups according to adenoma diameter: 10–19 mm (Group A, n = 36); 20–39 mm (Group B, n = 41); or ≥40 mm (Group C, giant prolactinomas, n = 17). Patients were followed for a mean of 7.5 years with sellar magnetic resonance imaging, visual fields and hormone measurements. Results: Mean baseline prolactin was 767, 2090 and 24,806 ng/ml in Groups A, B and C, respectively (p <.01). Prolactin suppression below three times the upper limit of normal (ULN) was achieved in 34 (94%; mean weekly cabergoline dose of 1.2 mg), 37 (90%; cabergoline dose, 2.1 mg) and 15 (88%; cabergoline dose, 2.8 mg) men (p =.31) in each group. After excluding patients who underwent surgery and radiotherapy, cabergoline suppressed prolactin below three times ULN in 32/35 (91%), 29/37 (78%) and 11/14 (79%) men in Groups A, B and C, respectively (p =.27). Visual deficits were observed in 5 (14%), 12 (29%) and 10 (59%) patients (p <.01); improvement was achieved in 5/5 (100%), 11/12 (92%) and 10/10 (100%) of men in Groups A, B and C. Low baseline testosterone was measured in 26 (72%), 39 (95%) and 17 (100%) patients in the three groups (p <.01). Following multi‐modal treatment, hypogonadism persisted in 3 (8%), 5 (12%) and 2 (12%) men, respectively (p =.85). Conclusion: Macroprolactinomas in men were controlled with cabergoline in 84% of cases, independent of tumour size. Pituitary surgery and adjuvant radiotherapy further improved long‐term response to 91%. [ABSTRACT FROM AUTHOR]

Purpose Methods Results Conclusions Glaucoma incidence in patients with endogenous Cushing's syndrome (CS) has never been established. We aim to assess the risk for glaucoma among CS patients compared to controls and determine the age of disease onset.A nationwide retrospective matched‐cohort study of patients with endogenous CS diagnosed between 2000 and 2023. Patients with CS were matched in a 1:5 ratio, with a control group individually matched for age, sex, socioeconomic status and body mass index. Main outcomes were the incidence of glaucoma and disease onset.A total of 609 patients [396 women (65%); mean age 48.1 ± 17 years] were included in the CS group and 3018 controls. Follow‐up duration was 14.6 years (IQR 9.8–20.2) for the study group. The aetiology of hypercortisolism was divided into pituitary (259, 42.6%), adrenal (206, 33.8%) and unconfirmed aetiology (144, 23.6%) patients. At baseline, 44 (7.2%) CS patients had a diagnosis of glaucoma, compared with 151 (5%) controls. The overall risk for glaucoma was 74% higher in patients with CS compared with matched controls (hazard ratio = 1.74, p = 0.002). Patients with CS who developed glaucoma were younger (mean age of 62 ± 14.7 years) than controls (mean ± SD age, 62 ± 14.7 years), (p = 0.02). The overall risk for glaucoma in CS was high for both patients in remission and patients with persistent hypercortisolism (p = 0.048). Patients with active hypercortisolism experienced an earlier glaucoma onset (82.1 ± 88.0 months).Endogenous CS is associated with increased risk for glaucoma regardless of remission status and develops at a younger age compared with the general population.

There is a limited literature discussing the long-term outcome of patients admitted to the emergency department with elevated blood pressure. The aim of the present study was to evaluate outcomes of patients with hypertension who attended an emergency department. All patients with hypertension who attended an emergency department without target organ damage were evaluated. A composite end point at 18 months, which included all-cause mortality, acute coronary syndrome, cerebrovascular accident, or hospitalization for heart failure, were compared between patients with hypertension and those with normotension. Overall, 410 patients were included in the study. Baseline characteristics were similar between patients with hypertension and those with normotension, except chronic renal failure being more prevalent in patients with hypertension. The composite primary end point occurred similarly in both groups; however, hospitalization for heart failure was significantly more common in patients with hypertension. Elevated blood pressure during an emergency department visit is associated with an increased risk for hospitalization for heart failure during an 18-month follow-up period compared with normotension.

Background:The association of blood pressure (BP) variability (BPV) in hospitalized patients, which represents day-to-day variability, with mortality has been extensively reported in patients with stroke, but poorly defined for other medical conditions. Aim and method:To assess the association of day-to-day blood pressure variability in hospitalized patients, 10 BP measurements were obtained in individuals ≥75 years old hospitalized in a geriatric ward. Day-to-day BPV, measured 3 times a day, was calculated in each patient as the coefficient of variation of systolic BP. Patients were stratified by quartiles of coefficient of variation of systolic BP, and 30-day and 1-year mortality data were compared between those in the highest versus the lowest (reference) group. Results:Overall, 469 patients were included in the final analysis. Mean coefficient of variation of systolic BP was 12.1%. 30-day mortality and 1-year mortality occurred in 29/469 (6.2%) and 95/469 (20.2%) individuals respectively. Patients in the highest quartile of BPV were at a significantly higher risk for 30-day mortality (HR =4.12, CI 1.12–15.10) but not for 1-year mortality compared with the lowest BPV quartile (HR =1.61, CI 0.81–3.23). Conclusions:Day-to-day BPV is associated with 30-day, but not with 1-year mortality in hospitalized elderly patients. [ABSTRACT FROM AUTHOR]
