Ectopic Cushing Syndrome (EAS) is a rare condition responsible for about 5-20% of all Cushing syndrome cases. It increases the mortality of affected patients thus finding and removal of the ACTH-producing source allows for curing or reduction of symptoms and serum cortisol levels. The aim of this study is to present a 20-year experience in the diagnosis and clinical course of patients with EAS in a single Clinical Centre in Southern Poland as well as a comparison of clinical course and outcomes depending on the source of ectopic ACTH production-especially neuroendocrine tumors with other neoplasms. Twenty-four patients were involved in the clinical study with EAS diagnosed at the Department of Endocrinology between years 2000 and 2018. The diagnosis of EAS was based on the clinical presentation, hypercortisolemia with high ACTH levels, high dose dexamethasone suppression test and/or corticotropin-releasing hormone tests. To find the source of ACTH various imaging studies were performed. Half of the patients were diagnosed with neuroendocrine tumors, whereby muscle weakness was the leading symptom. Typical cushingoid appearance was seen in merely a few patients, and weight loss was more common than weight gain. Patients with neuroendocrine tumors had significantly higher midnight cortisol levels than the rest of the group. Among patients with infections, we observed a significantly higher concentrations of cortisol 2400 levels in gastroenteropancreatic neuroendocrine tumors. Chromogranin A correlated significantly with potassium in patients with neuroendocrine tumors and there was a significant correlation between ACTH level and severity of hypokalemia. EAS is not common, but if it occurs it increases the mortality of patients; therefore, it should be taken into consideration in the case of coexistence of severe hypokalemia with hypertension and muscle weakness, especially when weight loss occurs. Because the diagnosis of gastroenteropancreatic neuroendocrine tumor worsens the prognosis-special attention should be paid to these patients.

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a large and very diverse group of neoplasms. Clinical presentation of NETs depends on the site of the primary tumor and whether the tumor is functioning (i.e., secreting peptides or neuroamines that produce symptoms). The diagnosis of GEP-NET is further complicated by symptomatic differences that occur depending on the type of secreted peptide or neuroamine. Due to their heterogeneity and unique characteristics, early diagnosis of GEP-NETs is difficult, which increases the likelihood of metastatic disease and reduces the scope of therapeutic possibilities. Thus, a multidisciplinary approach for the treatment of GEP-NETs is necessary. This review is the result of presentations that were delivered during an expert meeting on the treatment of GEP-NETs supported by Ipsen. We summarize the current knowledge on the epidemiology, incidence, diagnosis, and treatment of GEP-NETs. We examined the role of the somatostatin analog (SSA) lanreotide and the impact of the data from the recently published, randomized, double-blind, placebo-controlled CLARINET study (Controlled study of Lanreotide Antiproliferative Response In Neuroendocrine Tumors) on disease management. We also review the recent treatment options and recommendations for GEP-NETs.

Background The aim of this study was to validate in a 10-year follow-up the initial outcomes of various thyroid resection methods for multinodular non-toxic goiter (MNG) reported in World J Surg 2010;34:1203–13. Materials and methods Six hundred consenting patients with MNG were randomized to three groups of 200 patients each: total thyroidectomy (TT), Dunhill operation (DO), bilateral subtotal thyroidectomy (BST). Obligatory follow-up period of 60 months was extended up to 120 months for all the consenting patients. The primary outcome measure was the prevalence of recurrent goiter and need for revision thyroid surgery. The secondary outcome measure was the cumulative postoperative and post-revision morbidity rate. Results The primary outcomes were twice as inferior at 10 years when compared to 5-year results for DO and BST, but not for TT. Recurrent goiter was found at 10 years in 1 (0.6%) TT versus 15 (8.6%) DO versus 39 (22.4%) BST ( p  < 0.001), and revision thyroidectomy was necessary in 1 (0.6%) TT versus 5 (2.8%) DO versus 14 (8.0%) BST patients ( p  < 0.001). Any permanent morbidity at 10 years was present in 5 (2.8%) TT patients following initial surgery versus 7 (4.0%) DO and 10 (5.7%) BST patients following initial and revision thyroidectomy (nonsignificant differences). At 10 years, 23 (11.5%) TT versus 25 (12.5%) DO versus 26 (13.0%) BST patients were lost to follow-up. Conclusions Total thyroidectomy can be considered the preferred surgical approach for patients with MNG, as it abolishes the risk of goiter recurrence and need for future revision thyroidectomy when compared to more limited thyroid resections, whereas the prevalence of permanent morbidity is not increased at experienced hands.

Background/Objectives: Ectopic Cushing’s syndrome (ECS) is a rare, life-threatening condition caused by uncontrolled ACTH secretion from tumors, most commonly small-cell lung cancer (SCLC). ECS is traditionally reported in 1–6% of SCLC cases; however, recent data suggest it may be much higher. This study compares the clinical presentation of SCLC-related ECS (ECS-SCLC) with other ECS etiologies and analyzes the diagnosis, treatment, and outcomes of ECS-SCLC. Methods: We retrospectively analyzed the records of 39 ECS patients diagnosed between 2000 and 2024 at a tertiary endocrinology center. Seven cases (18%) were due to SCLC. Diagnosis was based on clinical signs, biochemical testing, imaging, and histopathology. Results: ECS-SCLC patients (five men, two women; median age 61), compared to other ECS etiologies, had a shorter time to diagnosis (median 1 vs. 2 months; p = 0.03), worse general condition (ECOG 4 vs. 3; p = 0.01), greater muscle weakness (Lovett scale median 2[IQR 1–2] vs. 2[IQR 2–3]; p = 0.04), more severe hypokalemia (2.12 vs. 2.7 mmol/L; p = 0.03), and required higher potassium supplementation (200 vs. 120 mEq/day; p = 0.001). All ECS-SCLC patients experienced weight loss (median 5 kg). Cortisol-lowering therapy (metyrapone or osilodrostat) was initiated in six patients (mean initiation time 3.7 days), leading to clinical improvement. Oncological treatment (chemotherapy or radiotherapy) was administered in five patients after stabilization. The median follow-up time was 3 months. Conclusions: Early recognition of ECS-SCLC and a multidisciplinary approach are critical. Severe hypokalemia and muscle weakness should prompt timely evaluation for hypercortisolism. Cortisol-lowering therapy may improve clinical status and facilitate oncological treatment.

The DE-PLAN was a European multicenter study, with the primary objective of testing whether a community-based lifestyle modification programme could serve as a means of primary prevention for type 2 diabetes (T2D) in high-risk individuals (based on the FINDRISC questionnaire). The aim of this study was to examine the impact of a 1-year community-based lifestyle intervention on health-related quality of life (HRQOL) in individuals from four participating European centers (Athens, Barcelona, Krakow, Kaunas), through a post-hoc analysis. Each center was allowed to implement different intervention strategies specifically tailored to the needs of their corresponding population sample. Before and after the intervention, participants underwent clinical evaluation, anthropometric measurements, an oral glucose tolerance test and lipid profile measurements. Health-related quality of life was assessed using the validated HRQOL-15D questionnaire. A difference of ±0.015 in the 15D questionnaire score was set as the threshold of clinically meaningful change. Data from 786 participants (67% females, mean age 59.7±9.4 years, BMI 31.5±4.5 kg/m2) with complete data regarding the HRQOL were analyzed (Athens: 104, Barcelona: 434, Krakow: 175, Kaunas: 70). After 1 year, a significant overall improvement in HRQOL was shown, as depicted by a change of 15D score from baseline value (0.88±0.9) to post-intervention (0.90±0.87, P<0.001), achieving the threshold of clinically meaningful change. A significant weight reduction was also observed (-0.8±4.0 kg, P<0.001). In multivariate analysis, improvement in HRQOL was independently associated with lower 15D score at baseline (P<0.001) and self-reported increase in overall exercise time (P<0.001) as assessed through specifically designed trial questionnaires. A community-based lifestyle intervention programme aiming at T2D prevention, applied on a heterogeneous population and with varied methods, was shown to improve overall health-related quality of life to a clinically meaningful degree.

Through pleiotropic effects related to the presence of its receptors in major human organs, vitamin D (VD) plays an important role in systemic homeostasis, especially in the proper functioning of muscles and bones. In light of the published data from both animal and human studies, VD deficiency should be considered a risk factor for obesity-related morbidity, prediabetes, and type 2 diabetes (T2D); in addition, VD supplementation in VD deficiency has a beneficial effect on the effects of treatments aimed at normalization of body weight (including incretin drugs) and the metabolism of carbohydrates in prediabetes and T2D. The objective of this paper is to present the current knowledge and evidence on the relationship between VD deficiency and obesity, prediabetes, and T2D. The paper is intended to be used as a practical guide. The authors propose that serum 25(OH)D concentrations be determined in adults who are obese or overweight (i.e., belonging to the group presenting with a multiple increase in the risk of VD deficiency) or adults who are obese or overweight and have prediabetes or T2D. The baseline VD levels should determine the therapeutic dose and be helpful in assessing the effectiveness of therapy. The available literature lacks precise information regarding the recommended doses of VD in obese people, with 4000 IU being a frequently suggested daily dose. Most papers recommend that body weight be taken into account when determining the dose of VD in the obese; the dose should be higher than in individuals with normal body mass index (BMI). The authors suggest that in the case of low VD levels (< 20.0 ng/mL), quite frequently as low as 12.0–15.0 ng/mL, in an adult obese patient, VD therapy should be started at 20,000 IU two times per week or 50,000 IU once a week with 25(OH)D and calcium levels being checked after one month so that a decision can be made on the further course of therapy. The suggested 25(OH)D concentration target range is > 30–50 ng/mL. In a patient-tailored supplementation model, the dose of VD should depend on body weight and, most importantly, on the baseline VD level. In the absence of the expected effects, the authors suggest that the dose of VD (usually vitamin D3) be increased or the treatment be switched to calcifediol or alfacalcidol, or calcitriol in special cases such as impaired kidney or liver function. It is important to emphasize the need to individualize the management and monitor blood calcium and creatinine levels during chronic VD therapy, including high-dose therapy.

Background Real life implementation studies performed in different settings and populations proved that lifestyle interventions in prevention of type 2 diabetes can be effective. However, little is known about long term results of these translational studies. Therefore, the purpose of this study was to examine the maintenance of diabetes type 2 risk factor reduction achieved 1 year after intervention and during 3 year follow-up in primary health care setting in Poland. Methods Study participants ( n = 262), middle aged, slightly obese, with increased type 2 diabetes risk ((age 55.5 (SD = 11.3), BMI 32 (SD = 4.8), Finnish Diabetes Risk Score FINDRISC 18.4 (SD = 2.9)) but no diabetes at baseline, were invited for 1 individual and 10 group lifestyle counselling sessions as well as received 6 motivational phone calls and 2 letters followed by organized physical activity sessions combined with counselling to increase physical activity. Measurements were performed at baseline and then repeated 1 and 3 years after the initiation of the intervention. Results One hundred five participants completed all 3 examinations (baseline age 56.6 (SD = 10.7)), BMI 31.1 (SD = 4.9)), FINDRISC 18.57 (SD = 3.09)). Males comprised 13% of the group, 10% of the patients presented impaired fasting glucose (IFG) and 14% impaired glucose tolerance (IGT). Mean weight of participants decreased by 2.27 kg (SD = 5.25) after 1 year ( p = <0.001). After 3 years a weight gain by 1.13 kg (SD = 4.6) ( p = 0.04) was observed. In comparison with baseline however, the mean total weight loss at the end of the study was maintained by 1.14 kg (SD = 5.8) (ns). Diabetes risk (FINDRISC) declined after one year by 2.8 (SD = 3.6) ( p = 0.001) and the decrease by 2.26 (SD = 4.27) was maintained after 3 years ( p = 0.001). Body mass reduction by >5% was achieved after 1 and 3 years by 27 and 19% of the participants, respectively. Repeated measures analysis revealed significant changes observed from baseline to year 1 and year 3 in: weight ( p = 0.048), BMI ( p = 0.001), total cholesterol ( p = 0.013), TG ( p = 0.061), fasting glucose level ( p = 0.037) and FINDRISC ( p = 0.001) parameters. The conversion rate to diabetes was 2% after 1 year and 7% after 3 years. Conclusions Type 2 diabetes prevention in real life primary health care setting through lifestyle intervention delivered by trained nurses leads to modest weight reduction, favorable cardiovascular risk factors changes and decrease of diabetes risk. These beneficial outcomes can be maintained at a 3-year follow-up. Trial registration ISRCTN, ID ISRCTN96692060 , registered 03.08.2016 retrospectively
