    Objective: Beta-thalassemia minor is a blood disease caused by a hereditary decrease in beta-globin synthesis, frequently leading to hypochromic microcytic anemia. Formerly called endothelial cell-specific molecule 1, endocan is a proteoglycan released by vascular endothelial cells in many organs. Our aim was to investigate the relationship between the beta-thalassemia minor patients and the healthy control group in terms of serum endocan level. Methods: The study was performed in a total of 80 subjects. They were divided into two groups, the beta-thalassemia minor group (n=40) and the healthy control group (n=40). Serum endocan levels, age, sex, body mass index value, and tobacco use data of these groups were compared. Results: No statistically significant difference was detected between the two groups in terms of age, sex, and body mass index values (p>0.05). Endocan levels were measured to be 206.85±88.1 pg/mL in the beta-thalassemia minor group and 236.1±162.8 pg/mL in the control group with no significant difference between the groups in terms of serum endocan levels (p>0.05). Conclusions: In our study, there was no change in endocan level in beta-thalassemia minor. This might be because serum endocan levels are affected by multi-factorial reasons. Serum endocan levels may be altered secondarily to decreased beta-globin chain, increased sympathetic activity due to anemia, or platelet dysfunction induced by oxidative stress in beta-thalassemia minor. Further multicenter studies involving more patients are necessary to demonstrate this.

    Background: Amikacin has the largest spectrum among aminoglycosides, its nephrotoxic effect limits its utilization. Our purpose in this study is to review the protective effect of dexpanthenol against the nephrotoxic effect of amikacin, accompanied with histopathological and biochemical parameters.

    Oxidative stress in maternal milk and cord blood in gestational diabetes mellitus: a prospective study.
    (2022-05-01T00:00:00Z) Erdoğan, Fırat; Şenkal, Evrim; Özer, Ömer Faruk; İpek, İlke Özahi; Altuntaş, Şükriye Leyla; Özde, Şükriye; ÖZER, ÖMER FARUK
    Background: Reduced antioxidant defenses may reflect a poor protective response against oxidative stress and this may be implicated in progression of gestational diabetes mellitus (GDM). Oxidative stress induced by hyperglycemia plays a major role in micro and macrovascular complications, which imply endothelial dysfunction. Objective: Our aim in this study was to investigate the association between GDM and oxidative stress markers measured in plasma, with regard to revealing changes to total antioxidant capacity (TAC) and total oxidant status (TOS) among mothers showing impairments in oral glucose tolerance tests (OGTTs). Design and setting: Prospective study at a university hospital in Turkey. Methods: The study group consisted of 50 mothers with GDM, and 59 healthy mothers served as controls. Umbilical cord blood samples were taken from all mothers during delivery and breast milk samples on the fifth day after delivery. TAC, TOS, thiol and disulfide levels were measured. Results: No statistically significant relationship between the blood and milk samples could be found. An analysis on correlations between TAC, TOS and certain parameters revealed that there were negative correlations between TOS and total thiol (r = -0.386; P < 0.001) and between TOS and disulfide (r = -0.388; P < 0.001) in milk in the control group. However, these findings were not observed in the study group. Conclusion: Our findings suggested that a compensatory mechanism of oxidative stress was expected to be present in gestational diabetes mellitus and that this might be ameliorated through good glycemic regulation and antioxidant supplementation.

    Could Vitamin K1 Deficiency be the Problem in Iron Deficiency and/or Anemia in Premenopausal Women?
    (2022-04-01T00:00:00Z) Karatoprak, Cumali; Şekerci, Abdusselam; Karaaslan, Tahsin; Olgaç, Atilla; Özer, Ömer Faruk; Selek, Şahabettin; Köktaşoğlu, Fatmanur; Ekinci, İskender; KARATOPRAK, CUMALİ; ŞEKERCİ, ABDÜSSELAM; ÖZER, ÖMER FARUK; SELEK, ŞAHABETTİN
    Objective: The etiology of iron deficiency anemia, which develops as a result of menstrual bleeding in the premenopausal period, is unknown. Vitamin K1 has an important role in the coagulation cascade and is not a well known vitamin. The aim of this study was to investigate whether or not Vitamin K1 had a role in anemia developing in the premenopausal period, for which no additional reason could be found. Methods: This study included a patient group of women aged 18-50 years, who had a regular menstrual cycle. Patients who were found to have iron deficiency, who were evaluated hematologically, gastrointestinally and gynecologically, and who did not have a pathology that would lead to iron deficiency were included in the study group.The control group comprised volunteers with regular menstrual cycles who had not been previously determined with iron deficiency. In the study, Vitamin K1, Hemogram, ferritin, iron, total iron binding capacity were examined. The Vitamin K1 level was measured by two different methods both using ELISA and liquid chromatography-mass spectrometry (LC-MS/MS) methods. In addition, a record was made for all participants including demographic characteristics, lifestyle habits, and number of menstruating days. The obtained data were then compared between the groups. Results: A total of 88 voluntary participants were included in the study as 45 patients with iron deficiency anemia (IDA) and a control group of 43 subjects. The age, body mass index, partial thromboplastin, International normalized ratio, active partial thromboplastin time, folic acid, and Vitamin B12 values were similar in both groups. In both methods, no significant difference was determined between the groups in respect of the Vitamin K1 level (p=0.9 in ELISA method and p=0.3 in LC-MS/MS method). The number of menstruation days was determined to be significantly higher in the anemic group than in the control group (p=0.002). Conclusion: From the results of this study, it was considered that IDA developed in premenopausal women with a longer period of menstrual bleeding. However, Vitamin K1 deficiency was not considered to be one of the underlying reasons for longer menstrual bleeding.
