Urinary early kidney injury molecules in children with beta-thalassemia major.

BACKGROUND: The aim of this study was to investigate novel urinary biomarkers including N-acetyl-ß-D-glucosaminidase (NAG), neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), and liver-type fatty acid binding protein (L-FABP) in children with ß-thalassemia major (ß-TM). MATERIALS AND METHODS: Totally, 52 patients (29 boys, 23 girls) with ß-TM and 29 healthy controls (3-17 years) were included. Various demographic characteristics and blood transfusions/year, disease duration, and chelation therapy were recorded. Serum urea, creatinine, electrolytes, and ferritin and urinary creatinine, protein, calcium, phosphorus, sodium, potassium, and uric acid in first morning urine samples were measured and estimated glomerular filtration rate (eGFR) was calculated. Routine serum and urinary biochemical variables, urinary NAG to Creatinine (U(NAG/Cr)), U(NGAL/Cr), U(KIM-1/Cr), and U(L-FABP/Cr) ratios were determined. RESULTS: Patients had similar mean serum urea, creatinine and eGFR levels compared with controls (p > 0.05 for all). The mean urinary protein to creatinine (U(Protein/Cr)) ratio was significantly higher in patients compared to the healthy subjects (0.13 ± 0.09 mg/mg and 0.07 ± 0.04 mg/mg, respectively; p < 0.001). Significantly increased U(NAG/Cr) (0.48 ± 0.58 vs. 0.23 ± 0.16, p = 0.026) and U(NGAL/Cr) (22.1 ± 18.5 vs. 11.5 ± 6.17, p = 0.01) ratios were found in ß-TM patients compared with healthy controls. However, no differences were found in serum and urinary electrolytes or U(KIM-1/Cr) and U(L-FABP/Cr) ratios between patients and controls (p > 0.05). Significant correlations were found between urinary biomarkers and urinary electrolytes (p < 0.05). CONCLUSIONS: Our results suggest that urinary NAG and NGAL may be considered to be reliable markers to monitor renal injury in ß-TM patients.

Use of complementary and alternative medicine in children who have no chronic disease.

AIM: In this study, we aimed to evaluate complementary and alternative methods of medicine, determine the frequencies of usage of these methods and investigate the factors which have an impact on their usage. MATERIAL AND METHODS: The study was conducted between October, the 15(th) and November, the 15(th) 2012. Approval was obtained from the local ethics committee (08.10.2012/732). The study form prepared was applied to the mothers of the children who presented to our general outpatient clinic and had no chronic disease. The data were recorded in SPSS for Windows v.16 program. Descriptive statistics, chi-square, Mann-Whitney U and logistic regression analyses were applied. A p value of <0.05 was considered significant. RESULTS: Two hundred and six children were included in the study. Complementary and alternative medicine was used in 83% of the patients. Wearing an evil eye (45%) bead and prayer (35%) to protect from the evil eye were the most commonly used methods. The most common medical conditions which caused to use of complementary and alternative medicine included anemia, diarrhea, constipation and cough. Belief-based application were being used in 73% of the patients and herbal methods were being used in 57%. In 18% of the patients, interventional methods including cutting had been performed. No difference was found between the patients in whom these methods were used and not used in terms of familial income, education levels of the parents, family type and residence (p>0.05). CONCLUSIONS: Complementary and alternative methods of medicine are applied substantially frequently in children. Physicians should have information about these methods in terms of their effects and side effects and warn families and especially mothers about potential risks.
