Leukemia mieloblastik akut (LMA) merupakan penyakit keganasan yang sering ditemukan pada anak. Hasil pengobatan LMA di Departemen Ilmu Kesehatan Anak RSCM dalam satu dekade terakhir belum pernah dievaluasi. Tujuan. Mengetahui karakteristik pasien LMA dan evaluasi hasil pengobatan serta protokol pengobatan.Metode. Penelitian deskritif dilakukan secara retrospektif terhadap rekam medis pasien LMA yang didiagnosis antara Januari 2007-Desember 2010 di Departemen Ilmu Kesehatan Anak RSCM. Karakteristik pasien secara klinis dan laboratoris dicatat, dan hasil pengobatan dianalisis. Estimasi kesintasan dihitung menggunakan metode Kaplan-Meier dengan bantuan program statistik.Hasil. Selama rentang waktu penelitian didapatkan 93 pasien baru LMA. Overall survival (OS) adalah 46,2% (95% IK: 21,1%;31,2%) dan event-free survival(EFS) 6,5% (95% IK: 3,1%;6,2%). Angka loss to follow-upmencapai sepertiga jumlah pasien yang mempengaruhi hasil estimasi kesintasan (overall survival). Ren...

In 1994, theHematology Oncology Working Group of the Indonesian PediatricAssociation constructed a national protocol based on standard in-ternational protocol. As the outcome was still not promising, in 1998the protocol was modified by introducing low dose MTX infusion forCNS prophylaxis.Objective To analyze the survival of pediatric ALL patient treated withthe modified protocol in Cipto Mangunkusumo Hospital, Jakarta.Methods A prospective study was carried out to all newly diag-nosed and relapsed children with ALL from January 1998 throughDecember 2004. Patients were stratified into standard risk group(SRG) and high risk group (HRG). HRG met with one of thesecriteria: WBC >50 000/ìl, the presence of CNS involvement, medi-astinal mass, relapse, or L 3 morphology. After completing induc-tion therapy, all patients received low-dose MTX (LDMTX) infusion(500 mg/m 2 ), espe...

In 12% of our thalassemia major patients investigated, we found two bands in the agarose gel-electrophoresis of PCR products from band 3 gene with a difference of 65 +/- 10 bp, equivalent to a deletion of 20 to 25 amino acids in band 3 protein. Thus, a co-existing band 3-mutant allele in addition to the thalassemic globin gene defects, could also contribute to erythrocyte membrane defects and to the spectrum of clinical symptoms of these thalassemia major patients.

Clinical examinations, review of medical charts, electrocardiography, echocardiography, and T2*CMR were performed. Cardiac siderosis was measured by T2*CMR conduction time. Left ventricle diastolic and systolic functions, as well as LV mass index were measured using echocardiography. Correlations between T2*CMR and echocardiography findings, as well as serum ferritin were determined using Pearson's and Spearman's tests. thirty patients aged 13-41 years were enrolled, of whom two-thirds had -thalassemia major and one-third had HbE/-thalassemia. Diastolic dysfunction was identified in 8 patients, whereas systolic function was normal in all patients. Increased LV mass index was found in 3 patients. T2*CMR condu...

A comparative cross sectional study was conducted in healthy, thalassemia major aged more than 12 year and seronegative HIV. They were matched in age and sex for splenectomised and non-splenectomised groups, analysing the non-spesific immune response (neutrophil count and phagocytosis) and specific immune response (count and function of cellular immunity). Infection episodes were also analized as immune response in vivo parameter. splenectomised thalassemia major showed increased neutrophil count but significantly decreased non-spesific immune response (neutrophil phagocytosis). Spesific immune response of splenectomised group presented significantly higher absolute lymphocyte, lymphocyte T, CD4+ and CD8+ counts compared to non-splenectomised thalass...
