Abstract:
Background: Differential diagnosis of Ischemic stroke (IS) and Hemorrhagic Stroke (HS) patient is crucial for augmenting the specific treatment. Objective: In the present study, we aimed to evaluate the role of the Inter-alpha-trypsin inhibitor heavy chain 4 (ITIH4) for the differential diagnosis of IS and HS patient. Material and method: This prospective study was carried out on 104 IS and 15 HS patients. Blood samples were collected at admission. Serum level of ITIH4 was estimated by indirect ELISA method using anti-ITIH4 peptide antibody (anti-ITIH4-peptide 1 to 9). Diagnosis sensitivity and specificity were determined by ROC curve analysis. Results: Out of panel of 9 antibodies, expression of Anti-ITIH4 peptide antibody 2 (p=0. 04), 5 (p=0.001), & 6 (p=0.0005) were significantly different between AIS and HS. Results shows sensitivity of 100%, 94%, 100% and specificity of 50% , 52% and 61% by anti-ITIH4 peptide antibody 2 (Cut off- >0.764; AUC- 0.720 ; 95% Cl 0.633-0.796), 5(Cut off- >0.774; AUC-0.779; 95% Cl 0.696-0.848) & 6 (Cut off- >0.738; AUC- 0.816; 95%Cl 0.737-0.879) respectively for differential diagnosis of AIS and HS.. Conclusion: Present study suggest that the Anti- ITIH4-peptide 2, 5, and 6 may be useful for differential diagnosis of IS and HS.
