Effectivity of Pancreatic Enzyme Replacement Therapy in Malnourished Children
(Wiley, 2020) Guven, Burcu; Mis, Mevsim Demir; Karaman, Kamuran; Yasar, Akkiz Sahin
Objective: Malnutrition is commonly seen in children with exocrine pancreatic insufficiency (EPI). Pancreatic enzyme replacement therapy (PERT) is the mainstay treatment of acute malnutrition in children detected with a disease closely associated with EPI (eg, cystic fibrosis). The effectiveness of PERT in children with malnutrition without any chronic disease, however, remains unclear. The aim of this study was to investigate the effectiveness of PERT on weight gain and EPI in children classified as moderately and severely malnourished according to the World Health Organization (WHO) classification. Materials and Methods: The study included a total of 40 children aged 2-16 years who were classified as moderately and severely malnourished according to the WHO classification. The patients were randomly divided into 2 groups: PERT group (n = 20) received 2000 U lipase/kg/day (in 4 doses) in addition to hypercaloric enteral supplements and control group received hypercaloric enteral supplements only. In both groups, anthropometric measurements and the assessment of fecal elastase-1 (FE-1) levels were performed both at first admission and at the end of the 8-week treatment period. Results: On the basis of WHO classification, 10 (25%) children were classified as severely malnourished and 30 (75%) children as moderately malnourished. EPI was detected in all the patients, among whom 24 (60%) patients had severe EPI. At the end of the treatment, body weight, height, and body mass index (BMI) increased significantly in both groups compared to their pre-treatment values, whereas no significant difference was found with regard to waist circumference (WC) and FE-1 levels. Similarly, no significant difference was found between pre- and posttreatment measurements of PERT and control groups (P > 0.05) and between pre- and posttreatment measurements of patients with moderate and severe malnutrition (P > 0.05). Conclusions: Malnutrition remains a serious public health problem, and thus, the development of novel treatment methods is highly essential. PERT is one of the most commonly considered alternatives, although there is little documentation of PERT in the literature. In the present study, although PERT resulted in higher weight gain, it established no significant difference between the 2 groups.
Evaluation of Renal Function Disorder With Urinary Neutrophil Gelatinase-Associated Lipocalin Level in Patients With Β-Thalassemia Major
(Lippincott Williams & Wilkins, 2019) Karaman, Kamuran; Sahin, Serdar; Geylan, Hadi; Yasar, Akkiz Sahin; Cetin, Mecnun; Komuroglu, Ahmet U.; Oner, Ahmet F.
Background and Aim: Neutrophil gelatinase-associated lipocalin (NGAL) is found in the granules of human neutrophils, with many diverse functions. Expression of NGAL is induced under various pathophysiological conditions, for example, infection, inflammation, kidney injury, cardiovascular disease, burn injury, and intoxication, and it has an important antiapoptotic and anti-inflammatory role. Patients and Methods: A total of 37 patients with thalassemia disease beta-thalassemia major (24 male and 13 female individuals) and 37 healthy controls (17 male and 20 female) were enrolled in this study. All patients were regularly transfused, and all of them were using oral chelator, deferasirox. Results: NGAL and cystatin C levels were significantly higher in the case group than in the control group. Conclusion: In patients with beta-thalassemia major, renal damage can occur owing to regular blood transfusion. Urinary NGAL levels in these patients may be considered as a marker for early renal injury.
Identification of Three Novel Pathogenic Itga2b and One Novel Pathogenic Itgb3 Mutations in Patients With Hereditary Glanzmann's Thrombasthenia Living in Eastern Turkey
(Taylor & Francis inc, 2021) Karaman, Kamuran; Yurekturk, Eyup; Geylan, Hadi; Yasar, Akkiz Sahin; Karaman, Serap; Aymelek, Huri Sema; Oner, Ahmet Fayik
Glanzmann's thrombasthenia (GT) is an autosomal recessive disorder in which the underlying problem is the lack or dysfunction of the GpIIb/IIIa receptor on the platelet surface. The present study determines the genetic mutation typology and analyzes the association between mutation types and clinical findings in patients diagnosed with GT who were followed up in Department of Pediatric Hematology of the Yuzuncu Yil University School of Medicine. The medical charts of 17 patients who underwent therapy and that were followed up in the Department of Pediatric Hematology of the Yuzuncu Yil University Dursun Odabas Medical Center between January 2008 and April 2018 were reviewed retrospectively. Data on such patient characteristics as present genetic mutations, age, gender, age at diagnosis, presenting symptoms, clinical findings, and platelet count and volume were garnered from the patient records. Of the 12 patients identified with genetic mutations, six had the same type of mutation, while four were identified with novel mutations that have to date not been defined in literature. Of these four mutations, three were located in the ITGA2B gene and one in the ITGB3 gene. The present study identified no significant association between the genetic and clinical findings of the patients. Novel mutations were identified in four cases in the present study. No association was found between the mutation type, and the bleeding scores and bleeding phenotypes of the patients. Further studies involving a larger number of patients are required to determine the relationship between the genotypes and clinical findings in patients with GT.
The Pattern of Tpeak-Tend Interval and Qtdis, and Pdis in Children With Brucellosis
(Oxford Univ Press, 2019) Cetin, Mecnun; Turfan, Nevzat; Karaman, Kamuran; Yasar, Akkiz Sahin; Guven, Burcu; Tuncdemir, Perihan
Objective: To investigate the effect of inflammation on the conducting system of the heart in patients diagnosed with brucellosis. Methods: A total of 42 patients diagnosed with brucellosis and 39 age and sex-matched healthy children were enrolled into the study. Pre- and post-treatment electrocardiographic parameters in brucellosis and control group were recorded from an electrocardiogram for each patient. Results: The results indicated that the parameters including Pmax, Pdis, QTmax, QTdis, QTcdis, Tp-edis interval and Tp-emax/QTmax and Tp-emax/QTcmax ratios, which are known to be key indicators for the prediction of severe atrial or ventricular arrhythmia and sudden cardiac death and also important parameters used as the indicators for the non-invasive evaluation of the transmural heterogeneity were significantly longer in the study group compared with the control group (p < 0.05). Conclusion: In this study, it was determined that the brucella disease had more cardiac involvement than thought, and this was more in the subclinical form of cardiac involvement.
Typhoid Fever Accompanied With Hematopoetic Lymphohistiocytosis and Rhabdomyolysis in a Refugee Child
(Lippincott Williams & Wilkins, 2019) Yasar, Akkiz Sahin; Karaman, Kamuran; Geylan, Hadi; Cetin, Mecnun; Guven, Burcu; Oner, Ahmet F.
Typhoid fever is an acute and systemic infectious disease that is specific to humans and is caused by Salmonella typhi. Patients may present with different findings ranging from simple fever to multiple organ failure. Hemophagocytosis and rhabdomyolysis are rare complications of typhoid fever. In this study, we presented a case of hemophagocytic lymphohistiocytosis and rhabdomyolysis in a 14-year-old girl who migrated from Mosul, Iraq, 1 month ago.
