Abstract
Background
This study aimed to evaluate the effectiveness of Intravenous immunoglobulin (IVIg) and combination of IVIg and Methylprednisolone for childhood Idiopathic (autoimmune) Thrombocytopenia (ITP) treatment; in addition investigate the related factors to develop chronic form of under 15 years ITP.
Materials and Methods
This retrospective study conducted on 88 ITP patients that treated with IVIg or combination of IVIg and Methylpredinosolon. Children were treated with IVIg 2 mg/kg/d or combination of IVIg 2 mg/kg/d and Methylpredinosolon20 mg/kg/dfor maximum 5 days. The numbers of patients with a platelet count > 50,000/μl, after treatment initiation, were the primary outcome. Odds Ratio (OR) as well as 95% Bayesian Credible interval (Crl), were estimated using a Bayesian Logistic regression model.
Results
The median age of subjects was 3.5+ 4.42 years (Interquartile: 2 8.5). About 13% of patients were discharged from hospitalization in day 2 and day 3. The ITP of 23% of children were progressed to chronic form. The following factors were significantly associated with the development of chronic ITP, combination of IVIg and Methylprednisolone [OR: 3.24, 95% Crl: [1.06 11.11]), and day 2 and 3 of discharge from hospitalization (OR: 7.72, 95% Crl: (1.14 67.16)].
Conclusion
The current results, suggest that the both IVIg and combination of IVIg are equally effective in providing a platelet level > 50,000/μl early. In addition patients how received combination drug were more likely to develop to chronic ITP. Therefore, we suggest that this route must be preferentially used in decision making for treatment childhood ITP.
