Background: Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder with a variable clinical course.
Methods: A retrospective analysis was carried out of ITP patients presenting to a pediatric hematology‐oncology department during a period of 20 years, with a focus on treatment and outcome.
Results: One hundred and twenty‐four cases were recorded (mean patient age, 8.4 years). Forty‐nine children (39.5%) had platelet counts <10 000/µL at diagnosis. No episode of severe bleeding was observed. Peak incidence was observed during spring and summer. Respiratory infections proceeded in 58% of cases. Treatment consisted of i.v. immunoglobulin (IVIG) in 93 children at four dosing schedules. Sixteen children received corticosteroids, 10 children received anti‐D immunoglobulin and 14 received no treatment. Recovery was observed in 67% of children on IVIG and in 50% on anti‐D globulin. Eight patients did not respond initially and received corticosteroids. Three children with refractory thrombocytopenia received anti‐CD20 (rituximab). Fourteen children (11%) had persistent/chronic disease. In 10 of them recovery was observed in 13 months–8 years. Splenectomy was performed in six children with resistant/chronic disease.
Conclusion: ITP has a benign course in the majority of cases. Anti‐D globulin can effectively be used as an alternative first‐line treatment. Rituximab can successfully be used in refractory cases, while splenectomy has currently limited indications.
Our results showed that genetic instability in the MS DNA, is present in asthmatic children, but to less extent than in adult asthmatics from previous studies. These findings may support the hypothesis that somatic mutations may be early acquired in the natural course of asthma and could represent another contributor to the molecular pathogenesis of the disease. However, further studies are needed to clarify this hypothesis.
