OBJECTIVE: It is well known that patients with endogenous Cushing's syndrome (CS) have decreased bone mass and enhanced risk for osteoporotic fractures, secondary to decreased bone formation and increased bone resorption. Immunological mediators, such as cytokines, have recently been shown to influence bone metabolism, and in the present study we examined serum levels of several cytokines, with known or potential effects on bone homeostasis, in 33 consecutive recruited untreated CS patients and 33 age-, sex- and body mass index-matched healthy controls. METHODS: Cytokine levels were measured by enzyme immunoassay and bone mass by dual-energy X-ray absorptiometry. RESULTS: Our main findings were (i) interleukin (IL)-8 and IL-18 levels were significantly increased in CS patients compared with controls. (ii) Levels of both IL-8 and IL-18 were positively correlated to serum cortisol. (iii) For serum levels of the 'classical' resorptive cytokines, i.e. IL-6 and tumor necrosis factor alpha, no significant differences were found between CS patients and controls. (iv) Raised IL-18 levels were correlated with decreased osteocalcin levels in CS patients. CONCLUSIONS: Our results demonstrated that CS patients have markedly elevated levels of the proinflammatory cytokines IL-8 and IL-18 in spite of high levels of the immunosuppressive hormone cortisol. These cytokines may be involved in the pathogenesis of disturbed bone homeostasis in CS.

Objectives. To investigate the efficacy and safety of perioperative endocrine therapy (PET) for patients with Cushing’s syndrome (CS) undergoing retroperitoneal laparoscopic adrenalectomy (RLA).Methods. The novel, simplified PET modality of 82 patients who underwent RLA procedures for CS were studied. Clinical manifestations were observed for all patients on days 1 and 5 postoperatively, and clinical data, such as blood pressure (BP), levels of serum cortisol, adrenocorticotropin (ACTH), blood glucose, and electrolytes, were acquired and analyzed.Results. Supraphysiological doses of glucocorticoid were administered during the perioperative period, and the dosage was reduced gradually. In all 82 cases, the RLAs were performed successfully without any perioperative complication, such as steroid withdrawal symptoms. The patient’s symptoms and signs were improved quickly and safely during the hospital days. The serum cortisol and potassium levels were rather stable on days 1 and 5 postoperatively, and most were within the normal range. The clinical manifestations, serum levels of cortisol, ACTH, and potassium in most patients restored to normal gradually after several months (mean, 6.7 ± 1.2 months), except for one patient undergoing bilateral adrenalectomy.Conclusions. This perioperative endocrine therapy for patients with Cushing’s syndrome (mainly for adrenocortical adenoma) undergoing retro-laparoscopic adrenalectomy is both effective and safe.

ObjectiveOsteoprotegerin (OPG) has been identified as a decoy receptor that inhibits osteoclast differentiation and, more recently, as a paracrine regulator of vascular calcification. OPG is suppressed by glucocorticoids (GC); however, results from experimental and clinical studies are not univocal. The aim of this study was to evaluate OPG and bone metabolism in patients with Cushing's syndrome (CS) before and after cure.Design and methodsTwenty-six patients with CS (all women, mean age: 39.1±11.9 years) and 24 age- and gonadal status-matched healthy women were studied for bone mineral density, bone metabolism, OPG, and receptor activator of nuclear factor-kB ligand at baseline. Twelve patients were also studied 6–18 months after surgery, with persistent normalization of cortisol levels.ResultsOPG was significantly higher and osteocalcin (OC) was significantly lower in CS patients than in controls (OPG: 4.17±1.23 vs 2.95±0.79 pmol/l, P=0.00001; OC: 15.0±6.1 vs 18.8±6.8 ng/ml, P=0.04 in CS and controls respectively). After cure, we found no difference in OPG levels, despite a significant increase in OC levels (from 16.4±11 to 37.2±15 ng/ml, P=0.03).ConclusionPatients with CS showed increased OPG serum levels that remained unchanged after recovery, despite a restoration of bone formation. We speculate that high levels of OPG could reflect the persistent damage of the GCs on cardiovascular system.

Summary Cushing’s syndrome is associated with increased morbidity and mortality. Although surgery is the first-line treatment, drugs can still play a role as an ancillary treatment to be employed while waiting for surgery, after unsuccessful operation or in patients unsuitable for surgery. We were asked to evaluate a 32-year-old male waiting for cardiac transplantation. Idiopathic hypokinetic cardiomyopathy had been diagnosed since 6 years. He was on treatment with multiple drugs, had a pacemaker, an implantable cardioverter and an external device for the support of systolic function. Physical examination showed severely impaired general status, signs of hypercortisolism and multiple vertebral compression fractures. We administered teriparatide, and the few evaluable parameters supported the diagnosis of ACTH-dependent hypercortisolism: serum cortisol was 24.2 µg/dL in the morning and 20.3 µg/dL after overnight 1 mg dexamethasone, urinary free cortisol (UFC) was 258 µg/24 h and ACTH 125 pg/mL. Pituitary CT was negative. Pasireotide 300 µg bid was administered and uptitrated to 600 µg bid. Treatment was well tolerated, achieving dramatic improvement of clinical picture with progressive normalization of serum cortisol and ACTH levels as well as UFC. After 4 months, the patient underwent successful heart transplantation. Many complications ensued and were overcome. Pituitary MRI was negative. On pasireotide 300 µg bid and prednisone 2.5 mg/day (as part of immunosuppressive therapy), morning serum cortisol and ACTH were 15.6 µg/dL and 54 pg/mL respectively, UFC was 37 µg/24 h, fasting glucose: 107 mg/dL and HbA1c: 6.5%. In conclusion, primary treatment with pasireotide achieved remission of hypercortisolism, thus allowing the patient to undergo heart transplantation. Learning points: Untreated Cushing’s syndrome is associated with ominous prognosis. First-line treatment is surgery (at pituitary or adrenal, according to disease localization). A few drugs are available to treat hypercortisolism. Pasireotide is a multi-ligand somatostatin analog approved for treatment of hypercortisolism. Primary treatment with pasireotide was effective in a patient with severe Cushing’s syndrome, allowing him to undergo heart transplantation.

Background Circulating microRNAs (miRs) are currently being investigated as novel biomarkers for osteoporosis and osteoporotic fractures. Aim The aim of this study was to investigate serum levels of specific microRNAs, known regulators of bone metabolism, in postmenopausal women with low bone mass and with or without vertebral fractures (VFs). Methods For the analysis, 14 miRs were isolated from the serum of 35 postmenopausal women with low bone mass and with at least one moderate VF and 35 postmenopausal women with low bone mass without fractures. Thirty postmenopausal women with normal BMD values and no history of fractures served as controls. Main outcome parameters were changes in the expression of selected miRs in the serum of patient population and compared with controls. Results From the 14 miRs that were selected, we identified 5 miRs, namely miR-21-5p, miR-23a, miR-29a-3p, miR-124-3p and miR-2861 that were significantly deregulated in the serum of patients with low bone mass compared with controls. Serum miR-124 and miR-2861 were significantly higher, whereas miR-21, miR-23 and miR-29 were lower in patients compared with controls. In a sub-group analysis of the patient population, the expression of miR-21-5p was significantly lower among osteoporotic/osteopenic women with VFs, showing 66% sensitivity and 77% specificity in distinguishing women with a vertebral fracture. Conclusion This study identifies a differential expression pattern of miR-21-5p in the serum of women with low BMD and VFs.

Purpose To investigate variations of circulating serum levels of interleukin-6 (IL-6), tumor necrosis factor alpha (TNFα), and interleukin-10 (IL-10) during three-dimensional conformal radiation therapy (3D-CRT) in patients with non–small-cell lung cancer and correlate these variations with the occurrence of radiation pneumonitis. Patients and Methods Ninety-six patients receiving 3D-CRT for stage I to III disease were evaluated prospectively. Circulating cytokine levels were determined before, every 2 weeks during, and at the end of treatment. Radiation pneumonitis was evaluated prospectively between 6 and 8 weeks after 3D-CRT. The predictive value of clinical, dosimetric, and biologic (cytokine levels) factors was evaluated both in univariate and multivariate analyses. Results Forty patients (44%) experienced score 1 or more radiation pneumonitis. No association was found between baseline cytokine levels and the risk of radiation pneumonitis. In the whole population, mean levels of TNFα, IL-6, and IL-10 remained stable during radiotherapy. IL-6 levels were significantly higher (P = .047) during 3D-CRT in patients with radiation pneumonitis. In the multivariate analysis, covariations of IL-6 and IL-10 levels during the first 2 weeks of 3D-CRT were evidenced as independently predictive of radiation pneumonitis in this series (P = .011). Conclusion Early variations of circulating IL-6 and IL-10 levels during 3D-CRT are significantly associated with the risk of radiation pneumonitis. Variations of circulating IL-6 and IL-10 levels during 3D-CRT may serve as independent predictive factors for this complication.

Lieberman SA, Eccleshall TR, Feldman D. ACTH-independent massive bilateral adrenal disease (AIMBAD): a subtype of Cushing's syndrome with major diagnostic and therapeutic implications. Eur J Endocrinol 1994:131:67–73. ISSN 0804–4643 A 49-year-old man with classic manifestations of Cushing's syndrome had undetectable levels of ACTH, lack of suppression of hypercortisolism with dexamethasone in doses of 2, 8, or 16 mg per day, bilaterally enlarged adrenal glands on MRI, and bilateral adrenal uptake of iodocholesterol. Preoperative treatment with ketoconazole lowered blood pressure and serum cortisol and produced symptoms of steroid withdrawal. Bilateral adrenalectomy revealed massively enlarged adrenal glands (left: 199 g, right: 93 g). Sequencing of the gene encoding the stimulatory G protein, Gsα, did not show either of two activating mutations previously reported in patients with McCune–Albright syndrome or acromegaly. Twenty-three previous cases of Cushing's syndrome due to ACTH-independent massive bilateral adrenal disease (AIMBAD) have been reported. AIMBAD may cause confusion in the differential diagnosis of Cushing's syndrome as endocrine testing suggests a unilateral, ACTHindependent process while adrenal imaging demonstrates bilateral abnormalities. Bilateral adrenalectomy is curative and appears to carry little risk of Nelson's syndrome. The pathogenesis of AIMBAD appears to be heterogeneous, as recent reports have demonstrated GIP-mediated hypercortisolism and familial AIMBAD. Transition from Cushing's disease to ACTH-independence is not supported by the available data. Future cases of AIMBAD should be investigated carefully to further elucidate the pathogenesis of this disorder.
