Abstract:
We demonstrated the clinical features and outcome of 87 children with idiopathic thrombocytopenic purpure (ITP). Most of them were younger children with severe thrombocytopenia; 71.3% were under 5 years old and 49.4% had platelet counts below 1×104/μl. Initial treatment consisted of high-dose intravenous immunoglobulin in 60 (69.0%), steroid in 10 (11.5%), and no therapy in 17 (19.5%). More than 90% of the children with platelet counts below 2×104/μl received treatment, but most children with platelet counts above 2×104/μl were observed without treatment. No patients had complications with CNS hemorrhage. Chronic ITP was noted in 17 patients (19.5%). Their mean age was 6 years 3 months compared with 2 years 8 months for the acute patients (p<0.01). But there were no significant differences in sex, platelet count, and initial treatment between chronic ITP and acute ITP. Six (35.3%) out of 17 children with chronic ITP subsequently achieved a spontaneous recovery. As of today, only 3 patients (3% of all patients, and 17.6% of patients with chronic ITP) have platelet counts below 5×104/μl. The overall prognosis and quality of life were excollent. Helicobacter Pylori (H. pylori) infection was found in 7.1% of the chronic patients and 5.3% of the acute patients, but platelet counts of them returned to normal without H. pylori eradication thrapy. It seemed that H. pylodi infection played a minor role in pediatric ITP.
