    Clinically “silent” giant pheochromocytoma. case report

    Acta Endo (Buc) 2013 9(1): 121-129 doi: 10.4183/aeb.2013.121

    Abstract
    Context. Clinically „silent“ pheochromocytomas are very rare tumors. Objective. We present a patient with incidentally discovered, asymptomatic benign pheochromocytoma and discuss its presentation and management. Conclusion. Considering the increasing incidence of adrenal incidentalomas and, therefore, pheochromocytomas too, every incidentally found adrenal mass has to be carefully examined regardless of its clinical presentation in order to prevent fatal oversight of possible secreting nature and/or malignant potential of the lesion and to ensure an adequate curable treatment.

    The Effect of Therapy with Insulin Analogues (Aspart and Glargine) on Oxidative Stress Parameters in Patients with Type 1 Diabetes Mellitus

    Acta Endo (Buc) 2023 19(4): 463-470 doi: 10.4183/aeb.2023.463

    Abstract
    Context. There are evidences that excessive production of reactive oxygen species is one of important abnormalities that contribute to development of chronic diabetic complications. Objective. To test the effect of intensive insulin therapy with analogues through the examining the level of oxidative stress parameters. Subjects and Methods. Comparison of data obtained by prospective analysis in 49 patients with T1DM was used, before and after six months of intensive insulin analog therapy. Results. The values of all three investigated parameters of oxidative stress malondialdehyde (MDA); xanthine oxidase (XO) and nitrates and nitrites (NOx) in our population with T1DM compared to the control (group of 42 voluntary blood donors) are statistically higher. The levels of antioxidant protection parameters compared to the control group also differ; the activities of catalase and glutathione peroxidase (GPx) are statistically higher in our population of T1DM patients compared to the control and superoxide dismutase (SOD) activities are statistically lower. The values of all three examined parameters of oxidative stress decrease after six months of intensive insulin analog therapy and were statistically lower after the therapy: for MDA p<0.001, for XO p<0.01 and for NOx p<0.05. The activities of catalase (p<0.001) and GPx (p<0.01) both decrease with therapy, while the activity of SOD is highest after the sixth month of therapy (p<0.001). Conclusion. In our patients with T1DM compared to the control the level of oxidative stress is significantly higher. Intensive insulin analog therapy with aspart and glargine promotes predominantly the improvement of oxidative stress, and in a less degree antioxidant protection.
