  • Growth Hormone Safety Workshop Position Paper: a critical appraisal of recombinant human growth hormone therapy in children and adults.
  • Ingår i: European Journal of Endocrinology. - : Society of the European Journal of Endocrinology. - 1479-683X.

    • Recombinant human growth hormone (rhGH) has been in use for 30 years, and over that time its safety and efficacy in children and adults has been subject to considerable scrutiny. In 2001, a statement from the GH Research Society (GRS) concluded that 'for approved indications, GH is safe'; however, the statement highlighted a number of areas for on-going surveillance of long-term safety including; cancer risk, impact on glucose homeostasis and use of high dose pharmacological rhGH treatment. Over the intervening years, there have been a number of publications addressing the safety of rhGH with regard to mortality, cancer and cardiovascular risk and the need for longterm surveillance of the increasing number of adults who were treated with rhGH in childhood. Against this backdrop of interest in safety, the European Society of Paediatric Endocrinology (ESPE), the GRS and the Pediatric Endocrine Society (PES) convened a meeting to reappraise the safety of rhGH. The ouput of the meeting is a concise position statement.

  • Diabetes in patients with acromegaly treated with pegvisomant : observations from acrostudy
  • 2019
  • Ingår i: Endocrine (Basingstoke). - : SPRINGER. - 1355-008X .- 1559-0100. ; 63:3, s. 563-572

    • PurposeTo explore the effects of pegvisomant (PEGV) on glucose metabolism in patients with acromegaly within ACROSTUDY, an international, observational, prospective safety surveillance study.MethodsPatients were retrospectively divided into two cohorts, with (DM group) or without diabetes mellitus (no-DM). Parameters of glucose metabolism and IGF-I values were analyzed yearly both cross-sectionally for 4 years (yrs) and longitudinally at 1 and 4-5yrs of PEGV treatment.ResultsAmong 1762 patients, 510 (28.9%) had DM before PEGV start. At cross-sectional analyses, in the DM group mean blood glucose was 140.058.7mg/dl at baseline, 116.4 +/- 44.8mg/dl at year 1 and 120.0 +/- 44.3mg/dl at yr 4. Mean HbA1c was 6.6 +/- 1.2 % at yr 1 vs. 7.0 +/- 1.4 % at baseline. HbA1c was above 6.5% in 61.9% at baseline and ranged from 45.4 to 53.8% at subsequent yearly time points. At the 4-yr longitudinal analysis, in the DM group (n=109), mean blood glucose decreased by 20.2mg/dl at yr 4, mean HbA1c was 7.0 +/- 1.5% at baseline vs. 6.8 +/- 1.4%. Patients achieved IGF-I normalization in 52.1% and 57.4% of cases in the DM and no-DM groups, respectively at 1 year. The mean daily PEGV dose (mg/day) was higher in the DM group (18.2 vs. 15.3) while the absolute change of IGF-I values from baseline was similar in both groups. PEGV was well tolerated in both groups without any unexpected AEs.Conclusions p id=Par4 Patients with DM had a moderate decrease in mean fasting glucose values during PEGV treatment.

  • Criteria for the definition of Pituitary Tumor Centers of Excellence (PTCOE): A Pituitary Society Statement
  • 2017
  • Ingår i: Pituitary. - 1386-341X .- 1573-7403. ; 20, s. 489-498

    • © 2017, The Author(s). Introduction: With the goal of generate uniform criteria among centers dealing with pituitary tumors and to enhance patient care, the Pituitary Society decided to generate criteria for developing Pituitary Tumors Centers of Excellence (PTCOE). Methods: To develop that task, a group of ten experts served as a Task Force and through two years of iterative work an initial draft was elaborated. This draft was discussed, modified and finally approved by the Board of Directors of the Pituitary Society. Such document was presented and debated at a specific session of the Congress of the Pituitary Society, Orlando 2017, and suggestions were incorporated. Finally the document was distributed to a large group of global experts that introduced further modifications with final endorsement. Results: After five years of iterative work a document with the ideal criteria for a PTCOE is presented. Conclusions: Acknowledging that very few centers in the world, if any, likely fulfill the requirements here presented, the document may be a tool to guide improvements of care delivery to patients with pituitary disorders. All these criteria must be accommodated to the regulations and organization of Health of a given country.

  • Diagnosis and management of acromegaly : the patient's perspective
  • 2016
  • Ingår i: Pituitary. - 1386-341X .- 1573-7403. ; 19:3, s. 268-276
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE:Early diagnosis is a success factor for the prevention of long-term comorbidity and premature death in patients with acromegaly, but large-scale data on the diagnostic process and disease management are scarce. Therefore, we aimed to evaluate the diagnostic process, implementation of treatment and changes in life situation in patients with acromegaly, focusing on sex-specific differences.METHODS:Non-interventional patient-reported outcome study. 165 patients with clinically and biochemically proven acromegaly were questioned about the diagnostic process and utilization of health care by means of a self-developed standardized postal survey including questions on acromegaly symptoms experienced before diagnosis, number and specialty of consulted doctors, time to diagnosis and aftercare.RESULTS:The diagnostic process took 2.9 (SD 4.53) years, during which 3.4 (SD 2.99) physicians were consulted. Women waited longer [4.1 (SD 5.53) years] than men [1.6 (SD 2.69) years; p = 0.001] for the correct diagnosis, and consulted more doctors in the process [4.0 (SD 2.99) vs. 2.7 (SD 2.84) doctors, p < 0.001, respectively]. In 48.5 % of patients, acromegaly was diagnosed by an endocrinologist (men: 45.1 %; women: 52.4 %). Overall disease duration from symptom onset until last surgery was 5.5 (SD 6.85) years, with no sex differences. A change in employment status was the most commonly reported event after diagnosis and a quarter of the patients stated that the illness had changed their lives.CONCLUSIONS:Our findings confirm the urgent need to increase awareness of the clinical manifestation of acromegaly to facilitate an earlier diagnosis of the disease and to provide diagnostic equality across the sexes.

  • Development of ACRODAT®, a new software medical device to assess disease activity in patients with acromegaly
  • Ingår i: Pituitary. - : Springer. - 1386-341X. ; 20:6, s. 692-701
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.
