(int Scientific information, inc, 2017) Garipardic, Mesut; Dogan, Murat; Bala, Keziban Asli; Mutluer, Tuba; Kaba, Sultan; Aslan, Oktay; Ustyol, Lokman
Background: The purpose of this study was to assess the values of the mean platelet volume (MPV) in children with attention deficit hyperactivity disorder (ADHD) and with autism spectrum disorders (ASDs) to determine the risk of cardiovascular disease in these 2 disorder groups. Material/Methods: The study included a total of 79 patients with ADHD or ASDs and controls in the Van region of Turkey. The control group included subjects of matching age and sex with no ADHD, ASDs, or chronic disease and taking no vitamins. The hematological parameters of the patients, including MPV, vitamin B12, and vitamin D, were assessed. Results: The study included a total of 79 children and adolescents aged 2-18 years (32 females and 47 males). Of the patients, 36 were in the ADHD group, 18 in the ASDs group, and 25 in the control group. There was no statistically significant difference in hematological parameters between the groups, but there were significant differences in terms of vitamin D and vitamin B12. The patient groups showed lower levels of vitamin B12 and vitamin D. In the ADHD group, there was a negative correlation between both vitamins and MPV (p<0.05). Partial correlation analysis of the ADHD group showed that MPV in particular was negatively correlated to vitamin D, and not to vitamin B12 (p: 0.03). Conclusions: Both ADHD and ASDs may accompany increased risk for cardiovascular disease due to the presence of vitamin B12 and D deficiency and their own characteristics. Therefore, these disorders should be closely followed up.
Hormone Disorder and Vitamin Deficiency in Attention Deficit Hyperactivity Disorder (Adhd) and Autism Spectrum Disorders (Asds)
(Walter de Gruyter Gmbh, 2016) Bala, Keziban Asli; Dogan, Murat; Kaba, Sultan; Mutluer, Tuba; Aslan, Oktay; Dogan, Sekibe Zehra
Background: The aim of this study was to analyze thyroid hormones and antibodies, ferritin, vitamins B12 and D, adrenal and gonadal steroid levels, and celiac antibodies in children diagnosed with attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). Methods: Between February 2014 and July 2014, a total of 77 children and adolescents (31 girls, 46 boys) who were admitted to the Van Training and Research Hospital were included in the study. The study population was divided into three groups including ADHD (n=34), ASD (n=16), and age-and sex-matched healthy controls (n=27). The diagnosis of ADHD was made on the basis of Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition (DSM-5) and DSM-4 Turkish version with the diagnostic interview and Disruptive Behavior Disorder Rating Scale (DBDRS). The diagnosis of ASD was based on the DSM-4 and DSM-5 Turkish version with the diagnostic interview and the Childhood Autism Rating Scale (CARS). The blood samples were obtained between 8: 00 and 9: 00 A.M. Results: There was a statistically significant difference in vitamin B12 and D levels and ferritin values among the three groups. The ASD group had the highest ferritin and the lowest vitamins B12 and D levels. Vitamin D levels of the ADHD group were significantly lower compared to the healthy controls. Conclusions: Our study results highlight the importance of supplementation of vitamins B12 and D in the ASD and ADHD patients.
Mean Platelet Volume and Vitamin D Deficiency
(Galenos Yayincilik, 2016) Bala, Keziban Asli; Dogan, Murat; Kaba, Sultan; Garipardic, Mesut; Aslan, Oktay; Dogan, Sekibe Zehra; Kocaman, Selami
Aim: To evaluate whether vitamin D deficiency has an effect on mean platelet volume (MPV). Materials and Methods: This was a retrospective study. The children followed-up at the pediatrics endocrinology polyclinic and diagnosed as nutritional rickets were included in this study. The patient group was created, and by screening the files of 478 case files, those compatible with the patient group for age and gender, were taken as the control group. Results: A total of 684 children and adolescents cases between the ages 0.1-18 years were included in the study. The cases were divided into 3 groups according to the vitamin D levels. Those with vitamin D levels of less than 15 ng/mL were classified as the vitamin D deficiency group, those between 15-20 ng/mL were classified as the insufficiency group, and those between 20-100 ng/mL were classified as the normal Vitamin D level group. There was no statistically significant difference between the groups in terms of age and gender. There was no significant difference observed between the groups in terms of the MPV levels. There was no statistically significant correlation determined in the correlation analysis between the vitamin D level and the MPV (p>0.05). In the multiple regression analysis, it was observed that vitamin D had no statistically significant effect on MPV. In the performed partial correlation analysis, when hemoglobin, hematocrit, calcium, phosphorus and parathyroid hormone were selected as controlling factors, again, there was no statistically significant correlation observed between the MPV and the vitamin D (r=-0.19, p>0.05). Conclusion: In the pathophysiology of the cardiac dysfunctions appearing as a result of vitamin D deficiency, we wished to emphasize that the hypothesis of the probable effect of vitamin D on MPV should be questioned in more detail.
The Syndrome of Inappropriate Secretion of Anti-Diuretic Hormone (Siadh) and Brucellosis
(int Scientific Literature, inc, 2016) Bala, Keziban Asli; Dogan, Murat; Kaba, Sultan; Akbayram, Sinan; Aslan, Oktay; Kocaman, Selami; Demir, Nihat
Background: Our study aimed to demonstrate the frequency of the syndrome of inappropriate ADH secretion (SIADH) and associated factors during the course of brucellosis in children and adolescents. Material/Methods: The study included children and adolescents aged 0-18 years old diagnosed with brucellosis between 2012 and 2014. The data were collected from patient charts. The diagnosis of brucellosis was made based on titrations > 1: 160 in standard Wright tube agglutination tests and/or positive culture tests. SIADH diagnosis was made based on the following criteria: euvolemic hyponatremia, serum Na+ <135 mmol/L, presence of serum hypoosmolarity (serum osmolarity <275 mOsm/L), increased urinary sodium (> 25 mmol/L with normal dietary salt intake), low uric acid (<2 mg/dL), absence of kidney, thyroid or adrenal disease, and any anti-diuretic use. Results: The study included 160 children and adolescents with mean age of 9.58 +/- 3.95 years (range: 2-18 years) including 70 girls (43.8%) and 90 boys (56.2%). When the patients were stratified based on SIADH, it was found that SIADH was present in 35 patients (21.9%). SIADH was associated with elevated glucose (p<0.001), ALT (p<0.05), AST (p<0.05), LDH (p<0.001), CRP (p<0.001), and MPV (p<0.001); and decreased potassium (p<0.05), chloride (p<0.001), albumin (p<0.001), total protein (p<0.05), and hemoglobin (p<0.05) levels. Conclusions: Our study reports on the frequency, clinical characteristics, predisposing factors, and management of SIADH that can develop in children and adolescents diagnosed with brucellosis.

Amaç: Retrospektif olarak planlanan çalışmada; 0-18 yaş arası tip 1 diyabetes mellituslu (DM) hastalarda demografik özellikler, tanı yaşları, metabolik kontrol durumları, tanı anındaki bulguları ve diyabete eşlik eden hastalıklarının olup olmadığının belirlenmesi amaçlanmıştır. Gereç ve Yöntemler: Çalışmamıza, Yüzüncü Yıl Üniversitesi Tıp Fakültesi çocuk endokrinoloji polikliniğimizden takip ve tedavileri yapılan; \"WHO\" kriterlerine göre tanı konulmuş eski ve yeni tanılı 0-18 yaş aralığında, 101 tip 1 DM hastası çocuk alındı. Bulgular: Tip 1 DM' li hastaların 43'ü (%42.6) kız, 58'i (%57.4) erkekti. Tanı yaşı ortalaması 8.3 ± 8.0 yıl (min:1 yıl, max: 16 yıl) idi. Hastaların başvuru anında %51.6' sında diyabetik ketoasidoz, %27.7' sinde hiperglisemi ve %20.7' sinde ketonemi saptandı. Eşlik eden otoimmün hastalıklar açısından değerlendirildiğinde tip 1 DM'lu 6 kişide (5.9%) çölyak hastalığı tespit edilmişken, 95 kişide (94.1%) eşlik eden herhangi bir otoimmün hastalık saptanmamıştı. Tip 1 DM'lu çocukların 2'sinde (1.9%) diyabetik nefropati gelişmişken, 99'unda (98.1%) diyabetin herhangi bir kronik komplikasyonu saptanmamıştı. Hastaların 8'i (7.9%) iyi metabolik kontrollü, 29'u (28.7%) orta metabolik kontrollü, 64'ü (63.4%) kötü metabolik kontrollü olarak saptandı. Sonuçlar: Çalışmamızda tip 1 DM' nin ilimizde erkek çocuklarda kızlara göre daha sık olduğu, tanıda ketoasidozla başvurunun daha çok görüldüğü, diyabetin ortaya çıktığı doruk yaşların 5 yaş öncesi ve erken puberte yaşları olduğu, en sık eşlik eden otoimmun hastalığın çölyak hastalğı ve en sık kronik komplikasyon olarak da nefropati geliştiği saptanmıştır.
