    The Role of RANKL and FGF23 in Assessing Bone Turnover in Type 2 Diabetic Patients

    Acta Endo (Buc) 2021 17(1): 51-59 doi: 10.4183/aeb.2021.51

    Context. Type 2 diabetes is a chronic metabolic disease which affects bone. There is evidence in the literature about some serum markers that reflect the bone turnover metabolism, such as RANKL (Receptor Activator of Nuclear factor Kappa-b Ligand) and Fibroblast Growth Factor (FGF) 23. Objective. We aimed to investigate the correlations between RANKL and FGF23 and other diabetes-related factors possibly influencing early bone turnover changes. Subjects and Method. We conducted a crosssectional analytical study on a group of 171 patients with type 2 diabetes, without Charcot’s arthropathy or a history of amputations, in which a complete history and anthropometric, clinical, biochemical and dietary evaluation were performed. We evaluated the serum level of RANKL and FGF 23. Results. RANKL was significantly lower in patients with macroangiopathy (0.42±0.15 pmol/L vs. 0.47±0.2 pmol/L, p=0.001). The level of FGF23 was lower in patients with neuropathy (0.37±0.36 pmol/L vs. 0.41±0.17 pmol/L, p=0.001). We found that FGF23 increased with age, but decreased with the duration of diabetes. We also found an inverse relationship between FGF23 levels and HbA1c, triglycerides, diastolic blood pressure, total proteins, albuminemia. Conclusions. RANKL was significantly lower in patients with macroangiopathy, and FGF 23 in patients with neuropathy. Therefore, more studies are needed to elucidate their role in early bone turnover changes.

    Pregnancy induced pseudo-primary hyperaldosteronism. new hemodynamic data

    Acta Endo (Buc) 2013 9(1): 63-69 doi: 10.4183/aeb.2013.63

    Introduction: Pseudo-primary hyperaldosteronism of pregnancy was previously reported by our group during correction in twin-to-twin transfusion syndrome (TTTS). Aim: Focus on plasma volume changes and renin-angiotensin (RAS) and aldosterone response in 45 TTTS patients requiring amnioreductions above 1000 ml for severe hydramnios. Methods: 45 patients necessitating placental surgery and amnioreduction >1000ml for severe TTTS, under local anesthesia, as previously described. Assesment of plasma volume variations (%ΔPV) and simultaneous assays of aldosterone, renin, angiotensin II and ANP performed by standard kits prior to, 6 hours after and 12-24 hours after procedure. Statistical results expressed as median and interquartile ranges for non-parametric data, after correction of post-op levels with %ΔPV. Results: Depletion of 1600 ml (1000-3700) amniotic fluid (extravascular depletion) unexpectedly increased the intravascular plasma volume by 20,38% and dramatically changed the hormonal picture of primary hyperaldosteronism. Aldosterone decreased from a median of 730 pg/ml (T0) to 553 pg/ml (T6) to 515,9 pg/ml (T24). ANP increased from 8,95 pg/ml (T0) to 14,51pg/ml (T6) to 19,9 pg/ml (T24) pg/ml (ANOVA p=0,0036), while renin and angiotenin II stayed unchanged (ANOVA p=0,91). Conclusion: Depletion of extracelular fluid (amnioreduction) is indicated for the correction of hyperaldosteronism in pregnancies with severe hydramnios, to reduce to normal the aldosteron levels without the interference of the renin-angiotensin system, while natriuretic activity increases through ANP and, possibly, other less known natriuretic factors .

    Correlation of the Daytime Sleepiness with Respiratory Sleep Parameters in Patients with Sleep Apnea and Type 2 Diabetes

    Acta Endo (Buc) 2011 7(2): 163-171 doi: 10.4183/aeb.2011.163

    Objective. The aim of the study was to test whether a correlation exists between the Epworth Sleepiness Scale (ESS) and respiratory sleep parameters in patients with\r\ntype 2 diabetes.\r\nDesign. Subjects and Methods.The records of 83 consecutive patients (mean age 54.6? 9.8 years) with type 2 diabetes\r\nthat accepted to perform an in-hospital sleep study for screening of sleep apnea have been retrospectively evaluated.\r\nResults. There was a weak positive correlation between apnea/hypopnea index (AHI), oxygen desaturation index and ESS, and a weak negative correlation between ESS and mean O2 saturation. When data was separately analyzed in men and\r\nwomen, it could not be identified any correlation between sleep respiratory parameters and ESS in men. In women,\r\ncorrelation coefficients increased, proving a stronger relationship between ESS and AHI (r=0.65, p<0.001), mean O2 saturation (r=-0.52, p=0.005) and oxygen desaturation index (r=0.60, p=0.001). ESS had only a moderate level of accuracy in identifying patients with moderate and severe sleep\r\napnea (sensitivity 84.1%, specificity 74.1%, PPV 84.1%, NPV 74.1%). In women ESS showed a higher sensitivity than in men\r\n(92% vs. 80.6%), but a lower PPV (63% vs.78.1%) in predicting the presence of an AHI &#8805; 15.\r\nConclusions. In women with type 2 diabetes, it is possible to suspect the existence of SAS solely on the basis of the\r\nESS score. In male population, symptoms evaluated by questionnaires, such as the ESS, provide additional information which combined with clinical findings are helpful in selecting patients who are candidates for further detailed sleep studies.

    Predictors of postprandial hyperglycemia in patients with type 2 diabetes

    Acta Endo (Buc) 2009 5(2): 177-182 doi: 10.4183/aeb.2009.177

    Objective. to investigate the factors associated with postprandial glucose excursions in\r\npatients with type 2 diabetes.\r\nResearch Design and Methods. A complete medical history and physical examination\r\nwere assessed in 118 consecutive patients with type 2 diabetes attending the Diabetes\r\nOutpatient Clinic, Cluj-Napoca. Blood samples were collected in fasting state, and HbA1c\r\nand lipid profile were assessed. A six points blood glucose profile measured by patients at\r\nhome was performed. To determine variables associated with higher postprandial glycemic\r\nlevels, factor analysis followed by linear regression model was performed.\r\nResults. The study group had a median age of 59.2 years, 43.4% were females. The\r\nmedian duration of diabetes was 5 years. By factor analysis we have extracted 4 factors that\r\nexplained 75.6% of the variance of postprandial glycemia: factor 1 with positive loadings of\r\ntotal cholesterol and LDL cholesterol, factor 2 with positive loadings of body mass index\r\nand waist circumference, factor 3 with positive loadings of diabetes duration and age, factor\r\n4 with positive loadings of triglycerides and glycosylated hemoglobin (HbA1c). After\r\nadjustment for the sex and treatment, only factor 2 and factor 4 remained significantly associated\r\nwith postprandial glycemic values (p=0.003 and p<0.001), indicating that the postprandial\r\nglycemia is best predicted by a multiple regression that included body mass index, waist\r\ncircumference, tryglicerides and HbA1c as independent variables (r=0.54, p<0.001).\r\nConclusion. The results of our study shows that low body mass index and waist\r\ncircumference, high triglycerides and HbA1c levels are independently associated with\r\npostprandial glucose excursions.

    Determinants of plasma adiponectin levels in patients with type 2 diabetes mellitus and microalbuminuria or low grade proteinuria

    Acta Endo (Buc) 2010 6(2): 181-189 doi: 10.4183/aeb.2010.181

    Background. Recent experimental data show that increased plasma adiponectin in chronic kidney disease could be a response to inflammation.\r\nObjective. To identify factors influencing adiponectinemia in patients with type 2 diabetes (T2DM) and microalbuminuria or low grade proteinuria.\r\nDesign. 32 patients with urinary albumin excretion rate (UAER)> 30 mg/g creatinine but without significant proteinuria (< trace COMBUR) were included and compared to 59 normalbuminuric T2DM controls. History, anthropometric measurements, laboratory analysis, total plasma adiponectin were obtained.\r\nResults. In our patients with UAER of 273.51?57.26 mg/g creatinine and estimated glomerular filtration rate (eGFR) 64.92?4.56 mL/min, in simple regression, adiponectinemia\r\ncorrelates inversely to eGFR (p=0.02, r= -0.38), triglyceridemia (p=0.03, r=-0.37) and hemoglobin\r\n(Hb -p= 0.01, r=-0.45) and positively to HDL cholesterol (p=0.001, r=0.54) and UAER (p<0.0001, r=0.71); the two latter parameters remain significant in multiple regression. In controls, adiponectinemia correlates inversely to age (p=0.04, r=-0.26) and BMI (p=0.04, r=-0.24); these and UAER predict adiponectinemia in multiple regression. 11 patients have UAE superior to 300 mg/g creatinine and 21 are strictly microalbuminuric (mean UAER 653.16?97.02 and 83.68?10.28mg albumin/g creatinine respectively). In microalbuminuric patients serum C reactive protein (CRP) correlates positively (p=0.0008, r=0.68) and Hb negatively (p=0.04, r=-0.41) to adiponectinemia; in multiple regression adiponectinemia only depends on CRP. In proteinuric patients CRP and\r\nglycated Hb correlate to adiponectinemia in stepwise multiple regression.\r\nConclusion. Adiponectinemia is mainly predicted by UAER in our cohort whereas it depends on age and BMI in normalbuminuric T2DM controls; in strictly microalbuminuric\r\npatients CRP is a major predictor of adiponectinemia.

    Neuroendocrine Renal Carcinoma – Therapeutic and Diagnostic Issues

    Acta Endo (Buc) 2016 12(3): 355-361 doi: 10.4183/aeb.2016.355

    Introduction. Neuroendocrine renal carcinoma represents less than 1% of all primary neoplasia of the kidney. Most frequently poorly differentiated carcinoma is diagnosed in advanced stages and they have an aggressive evolution and limited survival rate. Neuroendocrine carcinomas that arise from the renal pelvis are frequently associated with squamous cell carcinoma or adenocarcinoma. Material and method. We present the case of a female patient, known for 3 years before with an undefined retroperitoneal lymph node metastasis, being diagnosed at present with a left large cell neuroendocrine renal carcinoma, who initially had lymph node metastasis. Results. Until now, 118 cases of primary neuroendocrine renal carcinomas have been reported. A limited number of poorly differentiated neuroendocrine carcinomas have been reported. Discussion. Due to the clinical and biological findings, the aggressive evolution with early metastasis of lung and bone, the patient is included in the group of poorly differentiated carcinomas. In these cases, multimodal treatment is a gold standard. After surgical treatment and palliative chemotherapy with platinum salts, we obtained a partial remission of the disease and the control of symptoms. Conclusions. Regarding large cell neuroendocrine carcinoma, the surgical treatment remains the treatment of choice. Chemotherapy can determine limited results, improve the quality of life and enhance the overall survival rate.

    Acta Endo (Buc) 2011 7(4): 483-490 doi: 10.4183/aeb.2011.483

    Bisphosphonate-related osteonecrosis of the jaws (BRONJ) has been a rarely recognized condition. As the prescription of\r\noral bisphosphonates is universalized and the number of people treated with bisphosphonates is increasing, an accurate understanding and proper management of BRONJ are required.\r\nAim. Our aim was to describe the clinical features, treatments and prognosis of patients with oral bisphosphonate-related osteonecrosis of the jaws.\r\nMaterials and Methods. In our study BRONJ is reported in 20 consecutive patients who received BP therapy for osteoporosis with different drug schedules. The length of therapy was 7-73 months before osteonecrosis was observed; in 16 patients BRONJ involved the mandible and in 4 the maxilla. Systemic co-morbidities were present in seven patients, namely, rheumatoid arthritis (20), diabetes mellitus type 2 (10%) and chronic anemia (5%).\r\nResults. Nine of the 14 patients who did not suspend BP therapy demonstrated decreased pain and a clinically significant improvement in function. By using the authors? case series of 20 patients, which are reported in the article and the authors? clinical orientation to evaluation and treatment of oral bisphosphonate-related\r\nosteonecrosis of the jaws are presented.

    Changes in Bone Mineral Parameters after Sleeve Gastrectomy Relationship with Ghrelin and Plasma Adipokin Levels

    Acta Endo (Buc) 2018 14(4): 498-504 doi: 10.4183/aeb.2018.498

    Context. Metabolic surgery is currently the most efficient treatment for obesity, but concern is raised about the possible long-term nutritional side effects. Bone metabolism is often adversely affected after surgery, but literature data are contradictory. Objective. The aim of this study was to evaluate the evolution of bone mass parameters in the first year after laparoscopic sleeve gastrectomy in relation to anthropometric and body composition parameters and specific hormones of obesity. Design. We conducted a prospective study on 75 patients with obesity that underwent metabolic surgery over a course of 18 months at our center, with a follow-up period of 12 months. Subjects and Methods. All patients underwent a complex preoperative assessment and were required to return for medical follow-up at 6 and 12 months after surgery. Each visit included anthropometric parameters, DEXA and determination of specific hormonal parameters. Results. We noticed a significant improvement in anthropometric and body composition parameters after surgery. The value of adiponectin presented a significant increase after surgery and leptin showed a significant decrease at 6 and 12 months postoperative; ghrelin level decreased postoperative compared to preoperative, but without statistical significance. We observed no reduction in BMD after surgery, but a significant improvement in BMC at 12 months after surgery compared to preoperative. Ghrelin negatively correlated to BMD preoperative. Conclusions. Despite the significant alterations in anthropometric, body composition and hormonal parameters, we found no negative effect on BMD and BMC in our study population.
