Abstract

Introduction: Erythrocyte distribution width (RDW) is an important indicator of anisocytosis, which is used in the differential diagnosis of anemia and is easily accessible in the complete blood count results. Increased RDW values in coronary artery diseases, pulmonary hypertension and malignancies were detected in the studies. We aimed to demonstrate the usefulness of blood RDW level forthe differential diagnosis of granulomatous lymphadenitis associated with tuberculosis and sarcoidosis in our study.Materials and Methods: A total of 331 patients, 229 with sarcoidosis (stage I and stage II) and 102 with TB-LA and 50 healthy controlgroup were included in the study. The biopsies were obtained via EBUS-TBNA from 705 lymph nodes of 331 patients. Of tissuediagnosis was non-erosive granulomatous inflammation patients with tuberculosis negative proved by microbiological tests wereaccepted as sarcoidosis after other causes of granulomatous disease were excluded.Results: Of the sarcoidosis patients, 169 (73.7%) were in stage I, and 60 (26.3%) were in stage II. The mean RDW was 14.31 (±1.6) in the stage I group, 14.99 (± 2.3) in the stage II group, 14.11 (± 2.0) in the TB-LA group, and 13.89 (± 1.3) in the control group.There was a significant difference between the stage II group and the stage I, TB-LA, and control groups (p< 0.05 for all). There wasa significant difference in the C-reactive protein levels between the TB-LA and stage I groups (p< 0.01). The eritrocyte sedimentationrate values were higher in the TB-LA group than in both the stage I and stage II groups (p< 0.05).Conclusion: This is the first study to demonstrate the diagnostic value of RDW in patients with TB-LA and sarcoidosis (Stage I-II)patients diagnosed by EBUS-TBNA. Higher RDW in stage II sarcoidosis than in stage I, TB-LA and control group is related withparenchymal involvement and indicates active inflammation.

Özet

Giriş: Eritrosit dağılım genişliği (RDW), aneminin ayırıcı tanısında kullanılan, tam kan sayımı sonuçlarında kolaylıkla ulaşılabilen, anizositozun önemli bir göstergesidir. Yapılan çalışmalarda RDW değerinin koroner arter hastalıklarında, pulmoner hipertansiyonda, malignitelerde arttığı saptanmıştır. Çalışmamızda tüberküloz ve sarkoidoza bağlı granülomatöz lenf adenitlerin ayırıcı tanısı için kan RDW seviyesinin kullanılabilirliğini göstermeyi amaçladık. Materyal ve Metod: Çalışmaya toplamda 331 hasta, 229'u sarkoidoz (evre I ve evre II) ve 102'si TB-LA ile 50 sağlıklı kontrol grubu dahil edilmiştir. Biyopsi, 331 hastanın 705 lenf düğümünden EBUS-TBİA ile elde edildi. Doku tanısı nonkazeifiye granülomatöz iltihap olup balgam, bronş lavajı ARB’si ve kültürü negatif, PPD’si negatif hastalar, granülomatöz hastalık yapan diğer sebepler dışlandıktan sonra sarkoidoz kabul edildi. Tüm sarkoidoz hastaları evre I ve II olarak gruplandırıldı. EBUS-TBİA patoloji sonucu kazeifiye nekrozlu granülomatöz ve/veya granülomatöz iltihap olarak rapor edilip ya da TBİA materyalinde ARB ya da kültürü pozitif olan hastalar tüberküloz lenfadenit (TB-LA) kabul edildi. Bulgular: Sarkoidoz hastalarının 169’u evre I (%73.7), 60’ı evre II (%26.3) hastalardı. Ortalama RDW değerleri evre I ve evre II sarkoidozda 14.31 (± 1.6) ve 14.99 (± 2.3), TB-LA’da 14.11 (± 2.0) ve kontrol grubunda 13.89 (± 1.3) (p< 0.05) saptandı. Bazal RDW seviyesi gruplar arasında karşılaştırıldığında evre II ile evre I, TB-LA ve kontrol grup arasında anlamlı fark saptandı (p< 0.05). TB-LA ve evre I grupları arasında C-reaktif protein düzeylerinde anlamlı bir fark vardı (p< 0.01). Eritrosit sedimentasyon hızı değerleri TB-LA grubunda hem evre I hem de evre II gruplara göre daha yüksekti (p< 0.05). Sonuç: Bu çalışma EBUS-TBİA ile TB-LA ve sarkoidoz tanısı almış (evre I-II) hastalarda RDW’nin tanısal değerini gösteren ilk çalışmadır. Evre II sarkoidozda kan ortalama RDW seviyesinin evre I sarkoidoz,TB-LA ve kontrol grubuna göre anlamlı derecede yüksekliği parankim tutulumuyla ilşkili olup aktif inflamasyonu işaret etmektedir.
