ABSTRACT
Anemia of chronic disease (ACD)
frequently occurred in patients with chronic inflammatory diseases and can be
treated by treating the underlying disease. On the other hand, iron-deficiency
anemia (IDA), the most common type of anemia, occurred with iron
loss or when the iron requirement of the body was increased. Since the
treatment methods for ACD and IDA differ,
it is important to clinically distinguish between the two types of anemia. In
this study, we investigated and evaluated the performance of a number of
biomarkers, including ferritin, soluble transferrin receptor (sTfR), hepcidin,
C-reactive protein (CRP) and combination markers
containing ferritin for the diagnosis of IDA using serum samples from
Korean patients (80 ACD and 48 IDA Korean
patients). Among the single markers, ferritin exhibited the best performance
with 98.58% AUC and 97.50% sensitivity. In this study, a combination
of two biomarkers was used to differentially diagnose IDA and ACD.
Among the combination markers, ferritin + sTfR showed the best performance with
99.51% AUC and 98.75% sensitivity. We found that the ferritin +
sTfR combination showed the best diagnostic performance with 1.25% higher SN than
ferritin alone. Moreover, it also showed 10% better diagnostic performance than
the single ferritin marker within the data range where the distinction between ACD and IDA is unclear. We propose that using combination markers containing
ferritin may diagnose IDA more accurately and facilitate the
determination of the appropriate anemia treatment to expedite patient recovery.

ABSTRAK
Anemia penyakit kronik (ACD)
kerap berlaku kepada pesakit dengan penyakit radang kronik dan boleh
dirawat dengan merawat penyakit yang mendasarinya. Sebaliknya, anemia
kekurangan zat besi (IDA) adalah jenis anemia yang paling biasa berlaku dengan
kehilangan zat besi atau apabila keperluan zat besi dalam badan
bertambah. Oleh kerana kaedah rawatan untuk ACD dan IDA berbeza,
adalah penting secara klinikal untuk membezakan antara kedua-dua
jenis anemia. Dalam kajian ini, kami mengkaji dan menilai prestasi
beberapa penanda biologi, termasuk feritin, transferin larut reseptor
(sTfR), hepcidin, protein C-reaktif (CRP)
dan penanda gabungan yang mengandungi feritin untuk diagnosis IDA menggunakan
sampel serum daripada pesakit warga Korea (80 ACD dan
48 IDA pesakit warga Korea). Antara penanda tunggal, feritin
menunjukkan prestasi yang terbaik dengan 98.58% AUC dan
97.50% kepekaan. Dalam kajian ini, gabungan dua penanda biologi
telah digunakan untuk mendiagnosis IDA dan ACD secara
berbeza. Antara penanda kombinasi, feritin + sTfR menunjukkan prestasi
yang terbaik dengan 99.51% AUC dan 98.75% kepekaan. Kami mendapati
bahawa gabungan feritin + sTfR menunjukkan prestasi diagnostik yang
terbaik dengan 1.25% SN lebih tinggi daripada feritin sahaja.
Selain itu, ia juga menunjukkan prestasi diagnostik 10% lebih baik
daripada penanda feritin tunggal dalam julat data dengan perbezaan
antara ACD
dan IDA
adalah tidak jelas. Kami mencadangkan bahawa penggunaan
penanda gabungan yang mengandungi feritin boleh mendiagnosis IDA dengan
lebih tepat dan memudahkan penentuan rawatan anemia yang sesuai
untuk mempercepatkan pemulihan pesakit.
