with disease severity

Statement of the Problem:
Interleukin-2 is a potent signaling molecule in the signaling cascade of the immune-mediated activation
of T Lymphocytes leading to the destruction of hematopoietic stem cell. This forms the basis of Acquired Aplastic Anemia (AAA).
The objective was to study the association of IL-2 in the Bone Marrow Plasma (BMP) and Peripheral Blood Plasma (PBP) in AAA
patients.
Method:
Institutional ethical clearance was obtained and 52 BMP and PBP-paired samples were collected from the confirmed AAA
patients and 10 non-aplastic anemia controls. The level of IL-2 was measured by the quantitative enzyme-linked immunosorbent
assay. The IL-2 level was compared between the AAA and control subjects as well as among the various severity grades of AAA.
Mann-Whitney U test was used for statistical analysis.
Findings:
Significantly higher level of IL-2 was found in the BMP (75.33±41.9 vs. 3.12±1.82; p<0.00001) and PBP (48.54±21.89 vs.
1.99 ±1.25 p<0.00001) of AAA patients compared to the control subjects. The IL-2 levels were higher in patients with VSAA and SAA
than those with NSAA in the PBP (65.6±23.61 vs. 31.72±7.64; p=0.00338) and (45.37±16.25 vs. 31.72±7.64; p=0.01468), respectively.
The IL-2 levels were higher in patients with VSAA and SAA than those with NSAA in the BMP (115.01±38.91 vs. 38.32±19.49;
p<0.00001) and (66.44±23.34 vs. 38.32±19.49; p=0.0006). The IL-2 level was higher in VSAA than SAA in PBP (65.6±23.61 vs.
45.37±16.25; p=0.0114) and BMP (115.01±38.91 vs. 66.44±23.34; p=0.00044).
Conclusion:
Higher level of IL-2 in AAA patients compared to controls implies its role in the disease pathogenesis. Also, the higher
the level of IL-2, more severe is the disease emphasizing its role in the disease severity.
