Abstract

Fetal gender might affect the iron status of newborns. Hepcidin has an important role in the process of maternofetal iron transport. This study aims to compare the newborn iron status and the umbilical cord hepcidin levels between male and female gender. A cross-sectional study was conducted with subjects of 84 clinically healthy newborns. Written informed consent and ethical approval were carried out. Newborn iron status observed included (i) hematologic markers (RBC count, Hb, hematocrit, mean corpuscular volume (MCV) and red cell distribution width), and (ii) biochemical markers (serum iron (SI), serum ferritin (SF), soluble transferrin receptor (sTfR) and cord blood hepcidin). Hematologic markers were checked using Sysmex, XN-1000, while Hepcidin and sTfR were using ELISA. Serum iron was checked using IRON Flex®. Statistical analysis was tested with the independent t-test and the Mann-Whitney. All newborns and their mothers were in normal condition. The mean sTfR levels of newborns were significantly higher in the male group than females (38.3±9.06 vs. 34.3±8.16 nmol/L) with p=0.033. High sTfR levels reflect a low iron status. In conclusion, fetal gender differences influence the iron status of newborns, and male newborns have a potentially higher iron deficiency.

Abstract

Pemberian  transfusi  darah  kronik  pada  penderita  thalassemia  dapat   menyebabkan  kelebihan  kadar  besi.  Kelebihan  kadar besi  bebas  dalam  tubuh  akan  memacu  timbulnya  oksidan  berupa  reactive  oxygen  species   (ROS)  yang  diukur  dalam  bentuk malondialdehide  (MDA).  Peningkatan  produksi  ROS  dapat  menyebabkan  kerusakan  membran  sel  yang  mengandung senyawa lipid    termasuk eritrosit. T ujuan penelitian ini  adalah untuk menilai hubungan antara kadar MDA serum dengan kadar Hb penderita thalassemia. Metode penelitian ini  adalah penelitian observasional kohort prospective dilaksanakan di  UTD  PMI  Kota  Semarang.  Selama  bulan  Januari  2006  sampai  dengan  Desember  2009  dijumpai  32  penderita  thalassemia/HbE.  Variabel  penelitian kadar Hb dan MDA   serum.  Pengukuran dilakukan sebelum  transfusi  ke-1, setelah transfusi  ke-1 dan sebelum transfusi  ke-2. Analisis statistik menggunakan uji Mann-Whitney,  uji Wilcoxon  dan uji korelasi Spearman. Rerata  umur  subjek  penelitian  adalah  9,5±  3,13  tahun,  laki-laki  adalah  25  orang  (46,9%)  dan  perempuan  17  orang  (53,1%). Status  gizi  43,8  %  termasuk  gizi  kurang.  Kadar  MDA   kelompok   Hb  sebelum  transfusi  ke-2  8  g/dL  2,89±0,451  dan  kelompok Hb  >8  g/dL  2,19±0,792  (p=0,01).  Ada  korelasi  negatif  antara  Hb  sebelum  transfusi  ke-2  dengan  MDA  (r=min  0,52;  p=0,002). Dapat  disimpulkan  ada  korelasi  negatif  antara  kadar  MDA  serum  dengan  kadar  Hb  pada  penderita  thalassemia  /HbE. Kata  Kunci:  Hemoglobin,  MDA,  stres  oksidatif ,  thalassemia  /HbE
