The effect of mindfulness therapy in acromegaly, a pilot study.

BACKGROUND: Patients with acromegaly have often several comorbidities, including decreased quality of life, mood alterations and chronic pain. Mindfulness is effective at improving mood, quality of life and pain management; however, there is no data available on its effect in patients with acromegaly. OBJECTIVE: We aimed at evaluating changes in quality of life, mood, pain, sleep, self-compassion, life satisfaction, blood pressure and heart rate after a mindfulness program. DESIGN AND PATIENTS: This was a randomized, multicentre, international clinical trial (Barcelona-BCN and Bergamo-BG) of 60 patients, 30 per centre. MEASUREMENTS: The intervention group participated in an 8-week face-to-face group program; the control group followed normal clinical routine. In BG, patients performed a classic Mindfulness Based Stress Reduction program; in BCN they performed an adapted program including elements of mindfulness and compassion with a greater focus on daily life. RESULTS: In the BCN intervention group there was an increase in night-time hours in bed (p = 0.05) after the program. In both centres there was a trend to a reduction of the time to start sleeping (p = 0.06 BCN, p = 0.07 BG). In BCN, the intervention group reduced the pain score compared to the control group (p = .02), and an improvement in self-compassion was found (p = .04). In both centres, heart rate decreased significantly in the intervention group during a single 2-hour session. This was evidenced at the first and the last program session (BCN p = .013 and p = .009; BG < 0.001 and p = .04). A training effect was found in BG, where heart rate fell more in the last session than in the first (p = 002). CONCLUSIONS: We have demonstrated for the first time the value of a mindfulness program in patients with acromegaly, analysing possible effects and advantages, and clarifying the usefulness of a specific protocol for the disease.

CIBERER: Spanish national network for research on rare diseases: A highly productive collaborative initiative.

CIBER (Center for Biomedical Network Research; Centro de Investigación Biomédica En Red) is a public national consortium created in 2006 under the umbrella of the Spanish National Institute of Health Carlos III (ISCIII). This innovative research structure comprises 11 different specific areas dedicated to the main public health priorities in the National Health System. CIBERER, the thematic area of CIBER focused on rare diseases (RDs) currently consists of 75 research groups belonging to universities, research centers, and hospitals of the entire country. CIBERER's mission is to be a center prioritizing and favoring collaboration and cooperation between biomedical and clinical research groups, with special emphasis on the aspects of genetic, molecular, biochemical, and cellular research of RDs. This research is the basis for providing new tools for the diagnosis and therapy of low-prevalence diseases, in line with the International Rare Diseases Research Consortium (IRDiRC) objectives, thus favoring translational research between the scientific environment of the laboratory and the clinical setting of health centers. In this article, we intend to review CIBERER's 15-year journey and summarize the main results obtained in terms of internationalization, scientific production, contributions toward the discovery of new therapies and novel genes associated to diseases, cooperation with patients' associations and many other topics related to RD research.

Quality of life impairment after a diagnosis of Cushing's syndrome.

This brief review is devoted mainly to publications in the last 5 years dealing with health-related quality of life (QoL) after a diagnosis of endogenous hypercortisolism, due to pituitary-dependent Cushing's disease (CD) or any other cause of Cushing syndrome (CS). Despite improvement after treatment, persistent physical morbidity, neurocognitive problems like worse executive capacity and memory as well as stress intolerance, depressive symptoms and more anxiety, lead to long-term impairment of QoL.

Patient-reported outcomes in patients with acromegaly treated with pegvisomant in the ACROSTUDY extension: A real-world experience.

PURPOSE: To report the effects of pegvisomant (PEGV) treatment on patient-reported outcomes in acromegaly patients. METHODS: We conducted an extension study of an open-label, multinational, non-interventional study (ACROSTUDY) evaluating the long-term safety and efficacy of PEGV for acromegaly in routine clinical practice. Enrolled patients were rollover patients from ACROSTUDY, or treatment naïve/semi-naïve (NSN; no PEGV within 6 months of enrollment). Exploratory efficacy endpoints were changes in symptoms with the Patient-Assessed Acromegaly Symptom Questionnaire (PASQ) and quality of life with the Acromegaly Quality of Life questionnaire (AcroQoL) analyzed by controlled or uncontrolled IGF-I levels. Results were analyzed in all patients, in NSN patient subgroup, and by diabetes status. RESULTS: A total of 544 patients with acromegaly were enrolled, including 434 rollover subjects from ACROSTUDY and 110 NSN patients. Mean PEGV treatment duration was 7.8 years (range, 0-19.6 years). Overall, the majority of PASQ scores improved over time, but there was no significant difference between IGF-I controlled or uncontrolled groups. In the NSN subgroup, most PASQ and AcroQoL scores remained similar to baseline up to 1 year, regardless of IGF-I control. Patients with diabetes reported better PASQ scores over time with PEGV treatment, regardless of IGF-I control. IGF-I normalization increased from 10% of patients at baseline to more than 78% at year 10, with a mean daily PEGV dose of 18.7 mg. CONCLUSIONS: Overall, patients treated with PEGV had small improvements in PASQ. While IGF-I normalization increased with PEGV treatment, IGF-I control had no effects on PASQ and AcroQoL scores.

Hypopituitarism and pregnancy: clinical characteristics, management and pregnancy outcome.

PURPOSE: To describe the clinical characteristics, management and pregnancy outcome of women with prepregnancy hypopituitarism (HYPO) that received care at our center. METHODS: Retrospective study describing 12 pregnancies in women with prepregnancy HYPO (two or more pituitary hormonal deficiencies under replacement treatment) that received care during pregnancy at Hospital Santa Creu i Sant Pau. Clinical characteristics, management and pregnancy outcome were systematically collected. RESULTS: Average patients' age was 35 years and HYPO duration at the beginning of pregnancy was 19 years. The most frequent cause of HYPO was surgical treatment of a sellar mass (8 pregnancies). Eight pregnancies were in primigravid women and 10 required assisted reproductive techniques. The hormonal deficits before pregnancy were as follows: GH in 12 women, TSH in 10, gonadotropin in 9, ACTH in 5 and ADH in 2. All deficits were under hormonal substitution except for GH deficit in 4 pregnancies. During pregnancy, 4 new deficits were diagnosed. The dosage of replacement treatment for TSH, ACTH and ADH deficits was increased and GH was stopped. Average gestational age at birth was 40 weeks, gestational weight gain was excessive in 9 women, 8 patients required induction/elective delivery and cesarean section was performed in 6. Average birthweight was 3227 g. No major complications were observed. Five women were breastfeeding at discharge. CONCLUSIONS: In this group of women with long-standing HYPO, with careful clinical management (including treatment of new-onset hormonal deficits) pregnancy outcome was satisfactory but with a high rate of excessive gestational weight gain and cesarean section.

Resistance to first-generation somatostatin receptor ligands does not impair the results of gamma knife radiosurgery in acromegaly.

OBJECTIVE: Gamma knife radiosurgery (GKRS) has proven to be an effective adjuvant treatment for patients with acromegaly. We performed the present study to investigate, which would be the outcome of GKRS, independently on the response to somatostatin receptor ligand (SRL). DESIGN: Retrospective, observational study. PATIENTS: Ninety-six patients with active acromegaly were included. MEASUREMENTS: The cumulative probability of normalisation of insulin-like growth factor 1 (IGF-1) levels after GKRS was assessed by the Kaplan-Meier method. The association of several clinical characteristics with GKRS outcomes was explored with the use of a Cox proportional-hazard model with the relative hazard ratio and 95% confidence interval (CI). RESULTS: Resistance to SRL occurred in 39 of the 96 patients (40.6%). After GKRS, patients resistant to SRL had a 5- and 10-year probability of remission of 40.7% (95% CI: 23.7%-57.7%) and 75.9% (95% CI: 57.9%-93.9%), respectively. Patients responding to SRL had a 5- and 10-year probability of remission of 46.8% (95% CI: 32.2%-61.4%) and 58.1% (95% CI: 41.5%-74.7%), respectively. The difference was not significant (p = .48 by the log-rank test). Multivariate Cox analysis confirmed that the only independent variables associated with GKRS outcome were basal growth hormone (GH; p = .001) and IGF-1 multiple of the upper limit of normal levels before GKRS (p = .013). CONCLUSION: We demonstrate for the first time that the responsiveness to SRL has no effect on the probability to obtain remission of acromegaly after GKRS. The remission of disease occurred more frequently in patients who had lower GH and IGF-1 levels before GKRS.

Prevalence of sarcopenia after remission of hypercortisolism and its impact on HRQoL.

BACKGROUND: Cushing's syndrome (CS) is associated with skeletal muscle structural and functional impairment which may persist long-term despite surgical removal of the source of cortisol excess. Prevalence of sarcopenia and its impact on Health-Related-Quality of Life (HRQoL) in 'cured' CS is not known. There is a need to identify easy biomarkers to help the clinicians recognise patients at elevated risk of suffering sustained muscle function. PATIENTS AND METHODS: We studied 36 women with CS in remission, and 36 controls matched for age, body mass index, menopausal status, and level of physical activity. We analysed the skeletal muscle mass using dual-energy X-ray absorptiometry, muscle fat fraction using two-point Dixon magnetic resonance imaging and muscle performance and strength using the following tests: hand grip strength, gait speed, timed up and go and 30-s chair stand. We assessed HRQoL with the following questionnaires: SarQoL, CushingQoL, SF-36. We calculated the sarcopenia index (SI; serum creatinine/serum cystatin C × 100). RESULTS: Prevalence of sarcopenia, according to the European Working Group on Sarcopenia in Older People (EWGSOP), was greater in CS as compared with controls (19% vs. 3%; p < .05). Patients with sarcopenia had a lower SarQoL score than those without sarcopenia (61 ± 17 vs. 75 ± 14; p < .05), and scored worse on the items pain, easy bruising and worries on physical appearance (p < .05 for all comparisons) of the CushingQoL questionnaire. Patients with sarcopenia had poorer physical functioning on SF-36 than those without sarcopenia (60 ± 23 vs. 85 ± 15; p < .01). SI was lower in patients with sarcopenia than those without (71 ± 3 vs. 77 ± 2; p = .032), and was associated with intramuscular fatty infiltration, worse performance on the 30-s chair stand test, slower gait speed, and worse muscle weakness-related HRQoL, as measured using the SarQoL questionnaire (p < .05). The optimised cut-off value for the SI ratio to diagnose sarcopenia was 72, which yielded a sensitivity of 73% and a specificity of 90%. CONCLUSIONS: Sarcopenia is common in patients with CS in long-term remission, and associated with impaired quality of life. The SI is a potential biomarker allowing clinicians to identify patients at high risk of muscle dysfunction.

Molecular determinants of enhanced response to somatostatin receptor ligands after debulking in large GH-producing adenomas.

OBJECTIVE: Large somatotrophic adenomas depict poor response to somatostatin receptor ligands (SRLs). Debulking has shown to enhance SRLs effect in some but not all cases and tumour volume reduction has been proposed as the main predictor of response. No biological studies have been performed so far in this matter. We aimed to identify molecular markers of response to SRLs after surgical debulking in GH-secreting adenomas. DESIGN: We performed a multicenter retrospective study. PATIENTS: 24 patients bearing large GH-producing tumours. MEASUREMENTS: Clinical data and SRLs response both before and after surgical debulking were collected, and 21 molecular biomarkers of SRLs response were studied in tumour samples by gene expression. RESULTS: From the 21 molecular markers studied, only two of them predicted enhanced SRLs response after surgery. Tumours with improved response to SRLs after surgical debulking showed lower levels of Ki-67 (MKI67, FC = 0.17 and P = .008) and higher levels of RAR-related orphan receptor C (RORC) (FC = 3.1 and P Ë‚ .001). When a cut-off of no detectable expression was used for Ki-67, the model provided a sensitivity of 100% and a specificity of 52.6% with an area under the curve of 65.8%. Using a cut-off of 2 units of relative expression of RORC, the prediction model showed 100% of sensitivity and specificity. CONCLUSIONS: High levels of RORC and low levels of Ki-67 identify improved SRLs response after surgical debulking in large somatotropic adenomas. To determine their expression would facilitate medical treatment decision-making after surgery.

Craniopharyngioma in the Elderly: A Multicenter and Nationwide Study in Spain.

BACKGROUND: Craniopharyngioma (CP) is a rare tumor in the elderly whose clinical features and prognosis are not well known in this population. AIM: To evaluate the clinicopathological features and therapeutic outcomes of CP diagnosed in the elderly. PATIENTS AND METHODS: This was a retrospective, multicenter, national study of CP patients diagnosed over the age of 65 years and surgically treated. RESULTS: From a total of 384 adult CP patients, we selected 53 (13.8%) patients (27 women [50.9%], mean age 72.3 ± 5.1 years [range 65-83 years]) diagnosed after the age of 65 years. The most common clinical symptoms were visual field defects (71.2%) followed by headache (45.3%). The maximum tumor diameter was 2.9 ± 1.1 cm. In most patients, the tumor was suprasellar (96.2%) and mixed (solid-cystic) (58.5%). The surgical approach most commonly used was transcranial surgery (52.8%), and more than half of the patients (54.7%) underwent subtotal resection (STR). Adamantinomatous CP and papillary CP were present in 51 and 45.1%, respectively, with mixed forms in the remaining. Surgery was accompanied by an improvement in visual field defects and in headaches; however, pituitary hormonal hypofunction increased, mainly at the expense of an increase in the prevalence of diabetes insipidus (DI) (from 3.9 to 69.2%). Near-total resection (NTR) was associated with a higher prevalence of DI compared with subtotal resection (87.5 vs. 53.6%, p = 0.008). Patients were followed for 46.7 ± 40.8 months. The mortality rate was 39.6% with a median survival time of 88 (95% CI: 57-118) months. DI at last visit was associated with a lower survival. CONCLUSION: CP diagnosed in the elderly shows a similar distribution by sex and histologic forms than that diagnosed at younger ages. At presentation, visual field alterations and headaches are the main clinical symptoms which improve substantially with surgery. However, surgery, mainly NTR, is accompanied by worsening of pituitary function, especially DI, which seems to be a predictor of mortality in this population.

Patient-Centered Outcomes with Pituitary and Parasellar Disease.

Over the last 2 decades, advances in the diagnosis and management of pituitary diseases have made it possible to attain an endocrine "cure" in a large proportion of patients. In other words, tumors can be excised or controlled with drugs, mass effects of the lesion on surrounding structures can be solved, and pituitary deficiencies can be substituted with all relevant hormones. While this is considered a satisfactory outcome for health care providers, patients often suffer from an aftermath of prior endocrine dysfunction exposure, with irreversible effects, both physically and psychologically, which have a great impact on their everyday life. Diagnostic delay, often of several years, adds a negative impact on health perception. This affects their social, professional, and family domains and determines their future life. Understanding that this may occur is important, and health care providers should offer information to prepare the patient for this difficult journey, especially in the case of acromegaly, Cushing disease, or hypopituitarism. In order to maintain a good quality of life (QoL) in the long-term, patients need to adapt to this new situation, something that may be difficult, since they often cannot continue with all the activities and rhythm they used to do. Depression is often the consequence of maladaptation to the new situation, leading to impaired QoL.

Health-related quality of life improves 1 year after parathyroidectomy in primary hyperparathyroidism: A prospective cohort study.

OBJECTIVE: Impaired quality of life (QoL) in primary hyperparathyroidism (PHPT) is commonly present. Patients may complain about nonspecific neurocognitive symptoms which can be difficult to quantify. Two different disease-specific questionnaires have been developed, that is, the parathyroid assessment of symptoms score (PAS) and the primary hyperparathyroidism quality of life (PHPQoL). Using these two questionnaires, we assessed relationship between QoL and biochemical indices in PHPT and effects of parathyroidectomy (PTX). DESIGN: A prospective cohort study. METHODS: Patients with PHPT diagnosed from 2015 to 2017 were asked to answer the questionnaires before and 12 months after PTX. Biochemistry was obtained on both occasions. RESULTS: A total of 104 PHPT patients answered PAS and PHPQoL questionnaires at baseline, with a median age of 64 years (73% females). PHPQoL score correlated inversely with ionized calcium and PTH at baseline (P Ë‚ 0.04). Total PAS and PHPQoL score did not differ between those with and without osteoporosis, renal calcifications and impaired renal function. Based on levels of ionized calcium, PHPQoL differed significantly between patients with mild- and moderate-severe hypercalcemia (P = 0.01). Fifty-three patients answered PAS and PHPQoL 12 months after PTX showing an improved QoL at follow-up (Pall  Ë‚ 0.02). Stratifying patients into groups based on levels of ionized calcium showed a significantly improved PHPQoL score in patients with mild (˂1.45 mmol/L) as well as moderate-severe hypercalcemia (≥1.45 mmol/L) at follow-up (Pall  Ë‚ 0.03). CONCLUSION: Quality of life improved 12 months after PTX in PHPT patients. Impaired QoL seems to be associated with the degree of hypercalcemia rather than organ manifestations attributable to PHPT.

Worse Health-Related Quality of Life at long-term follow-up in patients with Cushing's disease than patients with cortisol producing adenoma. Data from the ERCUSYN.

OBJECTIVE: Hypercortisolism in Cushing's syndrome (CS) is associated with impaired health-related quality of life (HRQoL), which may persist despite remission. We used the data entered into the European Registry on Cushing's syndrome (ERCUSYN) to evaluate if patients with CS of pituitary origin (PIT-CS) have worse HRQoL, both before and after treatment than patients with adrenal causes (ADR-CS). METHODS: Data from 595 patients (492 women; 83%) who completed the CushingQoL and/or EQ-5D questionnaires at baseline and/or following treatment were analysed. RESULTS: At baseline, HRQoL did not differ between PIT-CS (n = 293) and ADR-CS (n = 120) on both EuroQoL and CushingQoL. Total CushingQoL score in PIT-CS and ADR-CS was 41 ± 18 and 44 ± 20, respectively (P = .7). At long-time follow-up (>1 year after treatment) total CushingQoL score was however lower in PIT-CS than ADR-CS (56 ± 20 vs 62 ± 23; P = .045). In a regression analysis, after adjustment for baseline age, gender, remission status, duration of active CS, glucocorticoid dependency and follow-up time, no association was observed between aetiology and HRQoL. Remission was associated with better total CushingQoL score (P < .001), and older age at diagnosis with worse total score (P = .01). Depression at diagnosis was associated with worse total CushingQoL score at the last follow-up (P < .001). CONCLUSION: PIT-CS patients had poorer HRQoL than ADR-CS at long-term follow-up, despite similar baseline scoring. After adjusting for remission status, no interaetiology differences in HRQoL scoring were found. Age and presence of depression at diagnosis of CS may be potential predictors of worse HRQoL regardless of CS aetiology.

A polymorphism in the CYP17A1 gene influences the therapeutic response to steroidogenesis inhibitors in Cushing's syndrome.

CONTEXT: Steroidogenesis inhibitors, such as ketoconazole (KTZ) and metyrapone (MTP), are used to lower hypercortisolism in patients with Cushing's syndrome (CS). Cortisol normalization is not reached in all patients taking these medications. OBJECTIVE: To test the hypothesis that variants in genes affecting steroidogenesis contribute to different responses to KTZ and/or MTP in patients with CS. PATIENTS AND METHODS: Fifty-four CS patients (46 women; mean [±SD] age, 39.7±12.7; 83% with Cushing's disease [CD] and 17% with an adrenal adenoma) preoperatively treated with KTZ (20%), MTP (37%) or a combination of both (43%). Thirty-nine of these (72%) were described in a previous study investigating the outcome of preoperative treatment with KTZ or MTP in CS patients. Following single-nucleotide polymorphisms (SNPs) were analysed: rs6410 (CYP11B1 gene), rs1799998 and rs4546 (CYP11B2 gene), and rs6163 (CYP17A1 gene). The associations between SNPs and cortisol levels at the end of medical treatment were evaluated. RESULTS: Normalization of urinary free cortisol (UFC) was achieved in 50% of patients after 5 months of treatment. Patients carrying the CC genotype of SNP rs6163 were more likely to be controlled than AC/AA (OR 0.25 [95%CI, 0.075-0.88]; P=.031). When only patients reaching eucortisolism after medical treatment were analysed, median interquartile range (IQR) duration of treatment was shorter in patients carrying the CC genotype of SNP rs6163 as compared to AA/AC carriers (4 [4.57] months vs 5.2 [6.1] months; P=.026). CONCLUSIONS: A polymorphism in the CYP17A1 gene was associated with the response to steroidogenesis inhibitors in CS. Genetic differences in the steroidogenic enzymes might account for inter-individual variations in the responsiveness to adrenal-blocking agents.

Impaired quality of life in patients with treated acromegaly despite long-term biochemically stable disease: Results from a 5-years prospective study.

OBJECTIVE: Patients with acromegaly demonstrate impaired quality of life (QoL), but data on long-term QoL changes in treated acromegaly are limited. This study evaluates and identifies factors that influence QoL in patients with long-term biochemical remission. DESIGN: The study consists of a cross-sectional arm comparing QoL between patients with treated and controlled acromegaly and healthy controls; and a longitudinal arm assessing QoL changes in patients with biochemically stable disease during 5.7±0.6 years of follow-up. PATIENTS: A total of 58 patients and 116 matched controls were recruited for the cross-sectional arm; 28 patients completed the longitudinal arm. MEASUREMENTS: Three generic questionnaires (Psychological General Well-Being Schedule [PGWBS], 36-item Short-Form [SF-36], EuroQoL [EQ-5D]) and the disease-specific acromegaly QoL questionnaire (AcroQoL) were applied. RESULTS: Quality of life assessment was performed 11.6±8.2 years following diagnosis and treatment of acromegaly. Patients with treated acromegaly had lower QoL scores compared with controls in all questionnaires with the exception of the PGWBS "Anxiety" subscale. The AcroQoL "Appearance" subscale and the "Physical Function" subscales of the remaining questionnaires were the most underscored domains. No difference in the total and subscale scores of all questionnaires was observed between baseline and follow-up, with the exception of the SF-36 "Physical Function," where a decline was found (58.5±24.7% vs 43.1±31.1%; P=.002). However, after adjusting for covariates, no significant change in any of the QoL scores was seen. Duration of IGF-1/GH control was positively correlated with QoL scores in most questionnaires at baseline, whereas use of GH lowering therapy at the time of QoL assessment was a negative predictive factor of QoL. CONCLUSION: Patients with biochemically controlled acromegaly demonstrate impaired QoL, which persists despite long-term disease control. This primarily consists of impaired physical function and secondly of impaired psycho-social well-being. Duration of biochemical disease control and current use of GH lowering therapy was the predominant factors determining patients' QoL.

Cystatin-C and epicardial adipose tissue as noninvasive predictors of cardiovascular risk in acromegaly.

BACKGROUND: Acromegaly (ACRO) is associated with elevated cardiovascular risk, although the prevalence of coronary artery disease (CAD) is unclear. Increased epicardial adipose tissue (EAT) and elevated cystatin-C (Cys-C) levels are cardiovascular risk factors, also related to the progression of CAD in several populations. AIMS: To measure the severity and extent of CAD in patients with ACRO and to determine whether either EAT or Cys-C reflect higher cardiovascular risk in patients with ACRO than in healthy controls. SUBJECTS AND METHODS: Case-control study, of 35 patients with ACRO (19 males, 17 with active disease) and 35 age-, gender- and body mass index (BMI)-matched healthy controls; mean age was 48·1 ± 8·1 years and mean BMI was 27·6 ± 4·8 kg/m2 . Cys-C was measured by an immunoturbidimetric assay. The 10-year risk of developing a coronary event was calculated using the Framingham Risk Score (FRS). EAT index (volume indexed to body surface area), and severity and extent of CAD were measured using a 256-slice multidetector computed tomography scanner (iCT-256 Philips Healthcare, Amsterdam). RESULTS: Coronary artery disease lesions, EAT index and severity/extent of CAD were similar between patients with ACRO and controls. Forty-four per cent of patients with ACRO had mild coronary lesions associated with greater EAT index (ß = 0·022, P = 0·036). Cys-C levels correlated with both EAT index (ρ = 0·386, P = 0·031) and FRS (ρ = 0·477, P = 0·004) in patients with ACRO only, despite similar prevalence of traditional cardiovascular risk factors. In a multiple linear regression model, both Cys-C levels (ß = 0·369, P = 0·007) and EAT index (ß = 0·29, P = 0·025) predicted FRS (R2 = 0·613). CONCLUSIONS: In patients with ACRO, both Cys-C and EAT index might be used as noninvasive predictors of cardiovascular risk.

Update on quality of life in patients with acromegaly.

In recent years, health-related quality of life (QoL) has been considered an important outcome for clinical management of acromegaly. Poor QoL has been described in acromegalic patients with active disease as well as after endocrine cure. It is known that acromegaly determines many physical problems and psychological dysfunctions that unavoidably impact on patients' QoL. Moreover, there is evidence that factors, such as radiotherapy or post-treatment GH deficiency also impair QoL in patients diagnosed with acromegaly. Thus, including the assessment of QoL in daily clinical practice has become fundamental to understand the consequences of acromegaly and the impact on the patients' daily life.

White matter involvement on DTI-MRI in Cushing's syndrome relates to mood disturbances and processing speed: a case-control study.

PURPOSE: Cushing's syndrome (CS) is an endocrine disorder due to prolonged exposure to cortisol. Recently, microstructural white matter (WM) alterations detected by diffusion tensor imaging (DTI) have been reported in CS patients, and related to depression, but other functional significances. remain otherwise unclear. We aimed at investigating in more depth mood symptoms in CS patients, and how these relate to cognition (information processing speed), and to WM alterations on DTI. METHODS: The sample comprised 35 CS patients and 35 healthy controls. Beck Depression Inventory-II (BDI-II) was used to measure depressive symptoms, State-Trait Anxiety Inventory (STAI) to assess anxiety, and processing speed was measured by the Symbol Digit Modalities Test (SDMT). DTI studies were acquired using a 3-Tesla Philips-Achieva MR-facility. Voxelwise statistical analysis of fractional anisotropy (FA), mean, axial and radial diffusivities (MD, AD, RD) data were performed using FMRIB Software Library. Correlation analysis were obtained between mood and processing speed variables, and FA, MD, AD and RD values, taking both CS patients and healthy controls. RESULTS: Active, controlled and cured CS patients showed greater depression (F = 12.4, p < 0.001), anxious state (F = 4.8, p = 0.005) and anxious trait (F = 9.6, p < 0.001) scores, than controls. Using the entire sample, depression scores correlated negatively to FA and positively to RD values. Although there were no differences in processing speed between groups, SDMT scores correlated positively to both FA and AD values. CONCLUSIONS: There were greater depressive and anxious symptoms in CS patients than in healthy controls, but no difference in processing speed. However, DTI is related to depression and information processing speed in CS.

Development of ACRODAT®, a new software medical device to assess disease activity in patients with acromegaly.

PURPOSE: Despite availability of multimodal treatment options for acromegaly, achievement of long-term disease control is suboptimal in a significant number of patients. Furthermore, disease control as defined by biochemical normalization may not always show concordance with disease-related symptoms or patient's perceived quality of life. We developed and validated a tool to measure disease activity in acromegaly to support decision-making in clinical practice. METHODS: An international expert panel (n = 10) convened to define the most critical indicators of disease activity. Patient scenarios were constructed based on these chosen parameters. Subsequently, a panel of 21 renowned endocrinologists at pituitary centers (Europe and Canada) categorized each scenario as stable, mild, or significant disease activity in an online validation study. RESULTS: From expert opinion, five parameters emerged as the best overall indicators to evaluate disease activity: insulin-like growth factor I (IGF-I) level, tumor status, presence of comorbidities (cardiovascular disease, diabetes, sleep apnea), symptoms, and health-related quality of life. In the validation study, IGF-I and tumor status became the predominant parameters selected for classification of patients with moderate or severe disease activity. If IGF-I level was ≤1.2x upper limit of normal and tumor size not significantly increased, the remaining three parameters contributed to the decision in a compensatory manner. CONCLUSION: The validation study underlined IGF-I and tumor status for routine clinical decision-making, whereas patient-oriented outcome measures received less medical attention. An Acromegaly Disease Activity Tool (ACRODAT) is in development that might assist clinicians towards a more holistic approach to patient management in acromegaly.

Quality of Life in Acromegaly.

Available disease-specific questionnaires like the Acromegaly Quality of Life questionnaire have confirmed that quality of life (QoL) is impaired in acromegaly, especially in active disease. Successful therapy improves QoL, but it may not normalize completely even after endocrine cure; furthermore, there is not always a correlation between growth hormone (GH) and insulin-like growth factor 1 and subjective health perception of QoL. Appearance is the dimension most affected and has the highest impact on the patient's QoL. Worse QoL is associated with the presence of musculoskeletal pain, headache (if only medical therapy, not surgery, has been provided), having required treatment with radiotherapy, being older, of female gender, with a longer disease duration, coexisting diabetes mellitus, a higher BMI or becoming GH deficient after treatment for acromegaly.

Effects of lanreotide Autogel primary therapy on symptoms and quality-of-life in acromegaly: data from the PRIMARYS study.

PURPOSE: To evaluate the effects of lanreotide Autogel on patient-reported outcomes and association with biochemical control, using PRIMARYS data. METHODS: PRIMARYS was a 1-year, open-label study of lanreotide Autogel (Depot in USA) 120 mg every 4 weeks in 90 treatment-naïve patients with acromegaly. Symptoms were assessed using Patient-assessed Acromegaly Symptom Questionnaire (PASQ) and health-related quality of life (HRQoL) using the AcroQoL questionnaire. Correlations between PASQ and AcroQoL scores, and between PASQ/AcroQoL and growth hormone (GH)/insulin-like growth factor-1 (IGF-1) levels were also evaluated (post hoc). RESULTS: Acromegaly symptoms and HRQoL significantly improved from week 12 to week 48, with modest correlations at week 48 between PASQ total score (R = -0.55, p < 0.0001) and AcroQoL global and physical scores (R = -0.67, p < 0.0001). Approximately 60% of patients achieved a minimal important difference (MID; improvement >50% of baseline standard deviation) in PASQ total score and >40% achieved a MID in AcroQoL global score (post hoc). Changes in PASQ scores were similar in biochemically controlled (GH levels ≤2.5 µg/L and normal IGF-1 levels) and uncontrolled groups, while changes in global and psychological AcroQoL scores were greater in the controlled group. There was no correlation between changes in PASQ or AcroQoL scores and changes in GH or IGF-1 levels. CONCLUSIONS: Primary treatment with lanreotide Autogel over 1 year was associated with rapid and sustained improvements in clinical signs and symptoms and HRQoL in patients with acromegaly. Improvements in HRQoL, but not symptoms, were greater in those achieving biochemical control (ClinicalTrials.gov: NCT00690898; EudraCT: 2007-000155-34).
