Multiglandular Hormone Deficiency in a Patient with Systemic Capillary Leak Syndrome

Systemic capillary leak syndrome (SCLS) is a rare but potentially fatal disorder characterized by a loss of fluid and proteins into the interstitial space leading to intravascular hypovolemia up to the point of hypovolemic shock. We report the case of a 64-year-old man with SCLS and multiple hormone abnormalities (primary hypothyroidism, hypoadrenalism, and hypogonadism), deficiency of hormone binding globulins, and hypogammaglobulinemia. The patient was successfully treated with intravenous immunoglobulins, theophylline, and terbutaline. Strikingly, with the dissolution of peripheral edema, hormone levels improved. To our knowledge, this is the first reported case of SCLS associated with polyglandular abnormalities

Long-term outcome of primary bilateral macronodular adrenocortical hyperplasia after unilateral adrenalectomy

CONTEXT Unilateral adrenalectomy has been proposed in selected patients with primary bilateral macronodular adrenocortical hyperplasia (PBMAH), but its long-term outcome is unclear. OBJECTIVE The aim of this study was to analyze long-term clinical and biochemical outcome of unilateral adrenalectomy versus bilateral adrenalectomy in patients with PBMAH in comparison to outcome of cortisol-producing adenoma (CPA) treated by unilateral adrenalectomy. DESIGN Retrospective observational study in three German and one Italian academic tertiary care center. PATIENTS AND METHODS 25 PBMAH patients after unilateral adrenalectomy (unilat-ADX-PBMAH), 9 patients with PBMAH and bilateral adrenalectomy (bilat-ADX-PBMAH) and 39 patients with CPA and unilateral adrenalectomy (unilat-ADX-CPA) were included. RESULTS Baseline clinical and biochemical parameters were comparable in unilat-ADX-PBMAH, bilat-ADX-PBMAH and unilat-ADX-CPA. Directly after surgery, 84% of the unilat-ADX-PBMAH patients experienced initial remission of Cushing's syndrome. In contrast, at last follow-up (median 50 months) 32% of the unilat-ADX-PBMAH patients were biochemically controlled compared to nearly all patients in the other two groups (p=0.000). Adrenalectomy of the contralateral side had to be performed in 12% of the initially unilat-ADX-PBMAH patients. 3 of 20 unilat-ADX-PBMAH patients (15%) died during follow-up presumably of Cushing's syndrome related causes whereas no deaths occurred in the other two groups (p=0.008). Deaths occurred exclusively in patients who were not biochemically controlled after unilateral ADX. CONCLUSIONS Our data suggest that unilateral adrenalectomy of PBMAH patients leads to clinical remission and a lower incidence of adrenal crisis, but less sufficient biochemical control of hypercortisolism potentially provoking a higher mortality

Association of C-terminal pro-endothelin-1 with mortality in the population-based KORA F4 study

Introduction: Endothelin-1 and its prohormone C-terminal pro-endothelin-1 (CT-proET-1) have been linked to metabolic alterations, inflammatory responses and cardiovascular events in selected study populations. We analyzed the association of CT-proET-1 with cardiovascular events and mortality, carotid intima-media-thickness as surrogate for early atherosclerotic lesions, biomarkers of subclinical inflammation and adipokines in a population-based study. Methods: The cross-sectional and prospective analyses used data from the KORA F4 study with a median follow-up time of 9.1 (8.8-9.4) years. Data on CT-proET-1 and mortality were available for 1554 participants, data on the other outcomes in subgroups (n = 596-1554). The associations were estimated using multivariable linear regression and Cox proportional hazard models adjusted for sex, age, body mass index, estimated glomerular filtration rate, arterial hypertension, diabetes, low-density and high-density lipoprotein cholesterol, current and former smoking and physical activity. The Bonferroni method was used to correct for multiple testing. Results: In the fully adjusted model, CT-proET-1 was associated with cardiovascular (hazard ratio (HR) per standard deviation increase: 1.66; 95% confidence interval (CI): 1.10-2.51; p = 0.017) and all-cause mortality (HR: 2.03; 95% CI 1.55-2.67; p < 0.001), but not with cardiovascular events, and was inversely associated with the intima-media thickness (β: -0.09 ± 0.03; p = 0.001). CT-proET-1 was positively associated with five out of ten biomarkers of subclinical inflammation and with two out of five adipokines after correction for multiple testing. After inclusion of biomarkers of subclinical inflammation in the Cox proportional hazard model, the association of CT-proET-1 with all-cause mortality persisted (p < 0.001). Conclusion: These results emphasize the complexity of endothelin-1 actions and/or indicator functions of CT-proET-1. CT-proET-1 is a risk marker for all-cause mortality, which is likely independent of vascular endothelin-1 actions, cardiovascular disease and inflammation

Corticotroph tumor progression after bilateral adrenalectomy (Nelson’s syndrome):systematic review and expert consensus recommendations

Corticotroph tumor progression (CTP) leading to Nelson's syndrome (NS) is a severe and difficult-to-treat complication subsequent to bilateral adrenalectomy (BADX) for Cushing's disease. Its characteristics are not well described, and consensus recommendations for diagnosis and treatment are missing

Time to diagnosis in Cushing’s syndrome: A meta-analysis based on 5367 patients

The time from first symptom to diagnosis of Cushing's syndrome is considered relevant for the severity of phenotype at presentation and long-term outcome. We therefore performed a systematic literature search to investigate relevant factors associated with a short time to diagnosis. The meta-analysis of 45 studies with 5560 patients showed significant differences for adrenal Cushing’s syndrome, Cushing’s disease and the ectopic Cushing’s syndrome. We did not find difference for gender, age or time of publication

Gpr124 is essential for blood-brain barrier integrity in central nervous system disease

Although blood-brain barrier (BBB) compromise is central to the etiology of diverse central nervous system (CNS) disorders, endothelial receptor proteins that control BBB function are poorly defined. The endothelial G-protein-coupled receptor (GPCR) Gpr124 has been reported to be required for normal forebrain angiogenesis and BBB function in mouse embryos, but the role of this receptor in adult animals is unknown. Here Gpr124 conditional knockout (CKO) in the endothelia of adult mice did not affect homeostatic BBB integrity, but resulted in BBB disruption and microvascular hemorrhage in mouse models of both ischemic stroke and glioblastoma, accompanied by reduced cerebrovascular canonical Wnt-β-catenin signaling. Constitutive activation of Wnt-β-catenin signaling fully corrected the BBB disruption and hemorrhage defects of Gpr124-CKO mice, with rescue of the endothelial gene tight junction, pericyte coverage and extracellular-matrix deficits. We thus identify Gpr124 as an endothelial GPCR specifically required for endothelial Wnt signaling and BBB integrity under pathological conditions in adult mice. This finding implicates Gpr124 as a potential therapeutic target for human CNS disorders characterized by BBB disruption

Therapeutic options after surgical failure in Cushing's disease: A critical review

Cushing's disease (CD) is the most common etiology of Cushing's syndrome (CD) due to corticotroph pituitary adenoma, which are in most cases small (80-90% microadenomas) and in about 40% cannot be visualized on imaging of the sella. First-line treatment for CD is transsphenoidal surgery (TSS) with the aim of complete adenoma removal and preservation of pituitary gland function. As complete adenoma resection is not always possible, surgical failure is a common problem. This can be the case either due to persistent hypercortisolism after first TSS or recurrence of hypercortisolism after initially achieving remission. For these scenarios exist several therapeutic options with their inherent characteristics, which will be covered by this review
