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

Low-grade inflammation during the glucocorticoid withdrawal phase in patients with Cushing's syndrome

IMPORTANCE Endogenous Cushing's syndrome (CS) leads to profound immunosuppression. Successful surgery induces biochemical remission and reversal of immunosuppression, which is characterized by clinical signs of glucocorticoid withdrawal and associated with increased susceptibility to infections and thromboembolic complications. OBJECTIVE We hypothesized that the glucocorticoid withdrawal phase is characterized by low-grade inflammation that may be related to patient-relevant outcomes. SETTING In this retrospective observational study, we analyzed longitudinal data from 80 patients with CS prospectively enrolled in the German Cushing's registry between 2012 and 2021. All enrolled patients underwent successful surgery. In a second step, a case-control study was performed in 25 of the patients with age-, gender-, and body mass index-matched control patients in whom hypercortisolism was excluded. Analyses included the inflammatory markers C-reactive protein and interleukin-6, as well as body composition, muscle function testing, and quality-of-life questionnaires. The patients were studied during active CS and in the postoperative remission phase 1, 3, 6, 12, and 24 months after surgery. RESULTS Compared with the preoperative phase and matched controls, patients with CS had increased systemic inflammatory markers in the early remission phase. One month following surgery, median (interquartile range) C-reactive protein was 0.48 mg dL-1 (0.14-0.90) vs 0.10 mg dL-1 (0.06-0.39) during active CS (P ≤ .001). Similarly, interleukin-6 1 month after surgery was 7.2 pg mL-1 (3.3-11.7) vs 1.7 pg mL-1 (1.5-2.5) during active CS (P ≤ .001). Obesity and hemoglobin A1c (HbA1c) were associated with increased inflammation levels. This proinflammatory state lasted until 1 year following surgery. Moreover, inflammatory markers during early remission showed an inverse correlation with long-term muscle function. CONCLUSIONS The glucocorticoid withdrawal phase is associated with a low-grade inflammatory state, which is particularly pronounced in obese and hyperglycemic patients and related to lower muscle function

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

Tearing energy as fracture mechanical quantity for elastomers

The fracture mechanical characterization of elastomeric materials is based on a global energy balance. Tearing energy was introduced in 1953 by Rivlin and Thomas to characterize the energy required for an infinitesimal increase in surface area during crack propagation. Enhancing the contributions of various energy dissipation mechanisms during the process of crack propagation is crucial for the understanding and modification of elastomeric materials with respect to an enhanced service life. Apart from the tearing energy, alternative fracture mechanical quantities based on the global energy balance are reviewed and discussed with respect to various influencing factors such as geometrical constraints of the specimen, specific loading conditions, and the specific material and its structural details. Finally, the application of advanced experimental methods characterizing the stages of crack initiation, propagation, and wear under more practical loading conditions are reviewed.597, DFG, California Department of Fish and Game; LO1504, NPU, Northwestern Polytechnical University; MŠMT, Ministerstvo Školství, Mládeže a Tělovýchovy; CZ.1.05/2.1.00/19.0409, CPS, Center for Produce Safety; HE4466/3-2, DFG, Deutsche Forschungsgemeinschaft; HE446/3-1, DFG, Deutsche Forschungsgemeinschaft; GR 1141/26-2, DFG, Deutsche Forschungsgemeinschaft; GR 1141/26-1, DFG, Deutsche Forschungsgemeinschaft; ERDF, European Regional Development Fund; Research and Developmen

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
