How Does Vaso-occlusive Crisis Alter Hematological Parameters in Sickle Cell Anemia?

Öz

Aim: To compare hematological parameters between children with steady-state sickle cell disease (SCD) and those with vaso-occlusive crisis. Materials and methods: Forty-seven patients (under 18 years of age) , 23 in the steady state and 24 in crisis were in this study. Control group included 24 age-matched children without chronic disease. Hematological parameters were recorded. Complete blood counts were measured by automated analyzer. Results: In crisis group, white blood cells (WBC), red cell distribution width (RDW), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), platelet (PLT), neutrophil and monocytes mean values (17045 /mm3, 21.62 %, 28.12 pg, 34.96 gr/dl, 432 x 109/L, 10858 /mm3, 1676 /mm3) were higher than control (7429 /mm3, 14.66 %, 26.49 pg, 33.65 gr/dl, 288 x 109/L, 3883 /mm3, 508 /mm3), (p<0.05). Red blood cell (RBC), hemoglobin (HGB), hematocrit (HCT) and mean platelet volume (MPV) levels (2.98 x106 /mm3, 8.35 gr/dl, 23.64 %, 9.46 fL) in crisis group were lower than control (4.75 x 106/mm3, 12.62 gr /dl, 37.49 %, 10.16 fL), (p <0.05). In steady-state group, RBC, HGB, HCT and MPV levels (3.19 x 106/mm3, 8.49 gr /dl, 24.77 %, 10.16 fL) were lower than control (4.75 x 106/mm3, 12.62 gr/dl, 37.49 %, 10.16 fL) (p<0.05). In steady-state group, WBC, RDW, neutrophils, lymphocytes and monocytes values (12924 /mm3, 21.37%, 10150 /mm3, 3985 /mm3, 1240 /mm) were higher than control (7429/mm3, 14.66%, 3883 /mm3, 2691 /mm3, 508 /mm3), (p<0.05). Conclusion: MCH, MCHC and PLT counts can be superior diagnostic markers for vaso-occlusive crisis

VASO-OKLUSİV KRİZ ORAK HÜCRELİ ANEMİDE HEMATOLOJİK PARAMETRELERİ NASIL DEĞİŞTİRİR?

Öz

Amaç: Vazo-oklüziv kriz ve stabil durumda orak hücre anemili (OHA) çocuklarda hematolojik parametreleri karşılaştırmak.

Gereç ve Yöntem: 18 yaş altında 47 hasta (24 vazo-oklüziv krizli ve 23 stabil) bu çalışmaya dahil edildi. Hasta grubu ile aynı yaş grubunda, kronik hastalığı olmayan, 24 çocuk kontrol grubu olarak seçildi. Demografik ve hematolojik parametreler kaydedildi. Tam kan sayımı otomatik analizör ile ölçüldü.

Bulgular: Kriz grubunda beyaz küre sayısı
(WBC), eritrosit dağılım genişliği (RDW), ortalama eritrosit hemoglobin (MCH), ortalama eritrosit hemoglobin konsantrasyonu (MCHC), trombosit (PLT), nötrofil ve monosit sayıları ortalamaları (17045 /mm3, %21,62, 28,12 pg, 34,96 gr/dl, 432 x 109/L, 10858 /mm3, 1676 /mm3 ) kontrol grubundan (7429 /mm3, %14,66, 26,49 pg, 33,65 gr/dl, 288 x 109/L, 3883 /mm3, 508 /mm3) yüksekti (p<0,05). Krizli grupta eritrosit sayısı (RBC), hemoglobin (HGB), hematokrit (HCT) ve ortalama trombosit hacmi (MPV) ortalamaları (sırasıyla: 2.98 x106/mm3, 8,35 gr/dl, %23,64, 9,46 fL) kontrol grubundan (4.75 x 106/mm3, 12,62 gr /dl, %37,49, 10,16 fL) düşüktü (p <0,05). Stabil grupta RBC, HGB, HCT ve MPV ortalamaları (sırasıyla: 3.19 x 106/mm3, 8,49 gr /dl, %24,77, 10,16 fL) kontrol grubundan (4.75 x 106/mm3, 12,62 gr/dl, %37,49, 10,16 fL) düşüktü (p<0,05). Stabil grupta WBC, RDW, nötrofil, lenfosit ve monosit sayısı ortalamaları (sırasıyla: 12924 /mm3, %21,37, 10150 /mm3, 3985 /mm3, 1240 /mm3) kontrol grubundan (7429 /mm3, %14,66, 3883 /mm3, 2691 /mm3, 508 /mm3) yüksekti (p<0,05). 

Sonuç: Bu çalışmada MCH, MCHC ve PLT sayımının vazooklüziv kriz için üstün bir tanısal belirteç olabileceği sonucuna varılmıştır.
