    A Different Perspective of Elevated Lactate in Pediatric Patients with Diabetic Ketoacidosis

    Acta Endo (Buc) 2020 16(1): 32-35 doi: 10.4183/aeb.2020.32

    Abstract
    Objective. This study aims to determine the frequency and prognostic significance of lactic acidosis in children with diabetic ketoacidosis (DKA) admitted to the pediatric intensive care unit. Methods. The study was carried out retrospectively by examining the patients admitted to the pediatric intensive care unit for the treatment of DKA. The ages of the patients ranged from 2 to 18 years. The patients with the following parameters were enrolled in the study: serum blood glucose>200 mg/dL, ketonuria presence, venous blood gas pH ≤7.1, bicarbonate <15. Results. A total of 56 patients were included in the study with a mean age of 111.07 ± 51.13 months. The recovery time from DKA was 16.05 ± 6.25 h in the group with low lactate level and it was 13.57 ± 8.34 h in the group with high lactate level with no statistically significant difference. There was a negative correlation between lactate levels and the recovery time from DKA. Conclusion. Lactic acidosis is common in DKA, and unlike other conditions, such as sepsis, it is not always a finding of poor prognosis that predicts the severity of the disease or mortality. We think that high lactate may even protect against possible brain edema-cerebral damage in DKA.

    Vitamin Deficiency and Insulin Resistance in Nondiabetic Obese Patients

    Acta Endo (Buc) 2016 12(3): 319-327 doi: 10.4183/aeb.2016.319

    Abstract
    Objective. Obese people may have nutritional deficiencies, although they are exposed to excessive food intake. We aim to assess relationship of vitamin D, B12, and folic acid levels and dietary vitamin intake and insulin resistance in obese people. Design. This case-control study was performed at the obesity outpatient clinics between March 2014 and April 2015. Subjects and Methods. We included 304 nondiabetic obese subjects in patient group and 150 normal weight individuals in control group. Patients were questioned in detail about their food intake. Results. Mean age of obese patients was 37.3±10.1 years, the mean duration of obesity was 7.9±5.4 years, and the percentage of female patients was 65.8%. Mean vitamin D, B12, and folic acid levels were significantly lower in patients than in controls. Vitamin D deficiency (<20 ng/mL) in 69.7%, vitamin B12 deficiency (<200 pg/mL) in 13.5%, and folic acid deficiency (<4 ng/mL) was found in 14.2% of the patients. BMI negatively correlated with vitamin D, B12, and folic acid levels. B12 levels negatively correlated with duration of obesity. Insulin resistance was found in 55.9% of patients and HOMA-IR levels negatively correlated with vitamin D and B12 levels. While dietary vitamin D and folic acid intakes were inadequate in all of patients, only 28.3% of patients had inadequate vitamin B12 intake. There was no relation between vitamin levels and dietary vitamin intakes. Conclusions. The study reveals that vitamin D, B12, and folic acid levels were low and poor vitamin D and B12 status were associated with insulin resistance in nondiabetic obese patients.

    Irisin and Chemerin Levels in Patients with Type 2 Diabetes Mellitus

    Acta Endo (Buc) 2019 15(4): 442-446 doi: 10.4183/aeb.2019.442

    Abstract
    Context. Changes in the secretion of signaling molecules that originates from adipose tissue and inflammation draw attention in the pathogenesis of type 2 DM. Chemerin, one of the signaling molecules of adipose origin, and irisin, defined as the Renaissance of the metabolism, are among these molecules. Objectives. This cross-sectional study was planned in order to compare the values of serum irisin and chemerin levels in patients newly diagnosed with T2DM and in healthy subjects. Subjects and Methods. The study included 41 patients newly diagnosed with T2DM and 49 healthy individuals. The chemistry parameters were analyzed with a biochemistry autoanalyzer, and hormonal parameters were analyzed with an immunoassay analyzer. Plasma irisin and chemerin levels were measured using the enzyme-linked immunosorbent assay method. Results. There was a significant difference between the groups in terms of glucose, HbA1C, Insulin, HOMA-IR and lipid panel results. Irisin levels in the group of patients newly diagnosed with T2DM were lower than in the control group. Chemerin levels in the group of patients newly diagnosed with T2DM were higher than in the control group. Conclusion. Consequently, diabetes-dependent changes in chemerin and irisin concentrations suggest that these two hormones have a role in the pathophysiology of DM. Further studies are required to understand the complex structure of the signaling pathways of chemerin and irisin molecules as well as the physiological importance of these molecules as metabolism regulators especially in humans.

    Factors CD10, cytokeratin 19 and staging-grading systems in predicting the prognosis of pancreatic neuroendocrine tumors (PNET)

    Acta Endo (Buc) 2012 8(4): 653-666 doi: 10.4183/aeb.2012.653

    Abstract
    Objective. This study was undertaken to examine prognostic factors in patients with pancreatic neuroendocrine tumors (PNET) undergoing surgical treatment to evaluate the prognostic value of recently introduced immunohistochemical staining methods of CD10 and cytokeratin 19. Materials and Methods. Tumors were classified on the basis of 2004 WHO Classification Guidelines and European Neuroendocrine Tumor\r\nSociety (ENETS) grading system. Immunohistochemical staining with Ki- 67, CD10 and cytokeratin 19 was performed. Results. A total of 36 patients with a mean age of 53.7 ? 12.0 years were included. Overall, 33 patients had a long-term follow-up with 10 patients (30.3%) experiencing recurrence. Seven\r\npatients (21.1%) died. Clinical parameters that were associated with recurrence included liver metastasis at the time of surgery and extra-pancreatic invasion (p < 0.005). Positive surgical margins, extra-pancreatic invasion, and multi-focal disease were associated with reduced survival (p < 0.05). In addition, there was an association between\r\nsurvival and WHO 2004 classification (p < 0.05).\r\nConclusions. Although vascular and peripancreatic invasion showed increased risk of recurrence, they were unrelated to survival. Of the histopathological examinations, Ki-67\r\nand mitotic activity showed a correlation with both recurrence and survival, while immunohistochemical\r\nstaining with cytokeratin 19 and CD 10 did not provide adequate prognostic information.
