Abstract

Amaç: Demir eksikliği anemisi (DEA) farklı sistemler için sorun olabilen yaygın bir bozukluktur. İnflamasyonun oluşturduğu anemi çalışılmakla birlikte, DEA’nın yol açtığı makrofaj aktivasyonu hakkında bilgi eksikliği bulunmaktadır. Bu çalışmada DEA ile makrofaj aktivasyonu arasındaki ilişkinin araştırılması amaçlanmıştır.

Hastalar ve Yöntem: Çalışmaya 88 kadın katılımcı alındı. Katılımcılar; 48 DEA hastası ve 40 sağlıklı kontroller olmak üzere iki gruba ayrıldı. M1 makrofaj aktivasyonu, triggering receptor expressed on myeloid cells-1 (TREM-1) düzeyleri ölçülerek değerlendirildi. CRP ve TREM-1 düzeyleri iki grupta karşılaştırıldı. TREM-1 düzeyleri ile vücudun demir durumu ve hemogram parametreleri arasındaki ilişki araştırıldı.

Bulgular: TREM-1 düzeyi, hasta grubunda kontrol grubuna göre daha yüksek saptandı [124.5 (6.8-770.5) pg/ml vs 48.5 (0.66-401.1) pg/ml, p=0.02]. CRP düzeyi her iki grupta benzerdi. Hasta grubunda TREM düzeyi ile hemoglobin, ortalama eritrosit hacmi, ferritin, transferrin saturasyonu, serum demiri arasında korelasyon saptanmadı (sırasıyla p değerleri 0.96, 0.14, 0.21, 0.16, 0.26).

Sonuç: Bu çalışmada DEA’da TREM-1 düzeylerinin artışının gösterilmesi, makrofaj aktivasyonunun göstergesi olabilir. DEA hastaları proinflamatuvar durumlar açısından göz önünde bulundurulabilir. Bahsedilen ilişki için daha kapsamlı çalışmalara ihtiyaç bulunmaktadır.

Does iron-deficiency anemia affect M1 macrophage activation and inflammation?

Abstract

Aim: Iron deficiency anemia (IDA) is a prevalent disorder and may be a problem for various systems. Anemia of inflammation has been extensively investigated before, but there is still a lack of knowledge about macrophage activation in IDA. Hence, the aim of this study was to investigate the relationship between IDA and macrophage activation.

Patients and Methods: The present study included 88 female subjects. The participants were divided into two groups: 48 IDA patients in the patient group and 40 healthy subjects in the control group. M1 macrophage activation was measured with the triggering receptor expressed on myeloid cells-1 (TREM-1). TREM-1 levels and C-reactive protein were compared between patient and control groups. The relationship between TREM-1 levels and hemogram parameters and iron status was investigated.

Results: TREM-1 levels of the patient group were significantly higher than of the control group [124.5 (6.8-770.5) pg/ml vs 48.5 (0.66-401.1) pg/ml, p=0.02], while CRP levels remained similar between the groups. There was no correlation between TREM-1 levels and hemoglobin, mean erythrocyte volume, ferritin, transferrin saturation and serum iron (p =0.96, 0.14, 0.21, 0.16, and 0.26, respectively) in IDA patients.

Conclusion: The present study showed that IDA might increase TREM-1 levels and this condition might be a clue of macrophage activation. IDA patients should be considered in terms of pro-inflammatory conditions and further investigations are needed to clarify the association mentioned above.
