Screening of blood donors in Indonesia against malaria with laboratory tests have not been done. Possible risk of malaria transmission through donated blood may occur and endanger the lives of recipients. Malaria in the city of Ambon by Annual Parasite Incidence was 4.49 - including High Case Incidence (HCI). This study aims to determine the prevalence of malaria with a several laboratory tests in the city of Ambon. Collection of total 550 donors at Red Cross blood transfusion unit Ambon, was carried out for a period of 3 months and followed by various examinations. The results showed none detected positive by microscopic examination or antigen rapid test PfHRP2-aldolase or PfHRP2-LDH. Twenty-two donors were found to contain P. falciparum with immunoglobulin antibody rapid test, in addition five other donors positive by PCR using 18S rRNA. This study showed that the potency of malaria transmission by blood donors was 4.9% in the island of Ambon."

"[ABSTRAKLatar belakang. Komponen darah washed erythrocyte (WE) mempunyai fungsi yang sama dengan leukodepleted PRC (LD-PRC) yaitu untuk mencegah atau mengurangi reaksi transfusi. Namun banyak kekhawatiran para klinisi tentang cara pembuatan komponen darah WE dan bahan yang terkandung pada filter leukosit untuk menangkap leukosit. Tujuan utama dari penelitian ini adalah memberikan bukti secara ilmiah akan keamanan dalam pemakaian komponen darah PRC yang telah dimodifikasi ini dan juga memberikan pemahaman tentang pemakaian yang benar untuk komponen darah ini. Metoda. Penelitian ini menggunakan desain potong lintang pada 52 sampel darah. Pemeriksaan darah dilakukan pada 26 sampel WE sebelum dan sesudah menjadi komponen darah WE dan 26 sampel LD-PRC sebelum dan sesudah menjadi komponen darah LD-PRC. Pemeriksaan hematologi diperiksa secara otomatis menggunakan Sysmex Xn-2000, total protein diperkirakan menggunakan ADVIA 1650/1800, sedangkan hemolisis darah diamati menggunakan uji Osmotic Fragility Test (OFT). Hasil. Menunjukan kadar hemoglobin pada kelompok WE berkurang 15,4%, volume hematokrit menurun 8,55%, kadar protein menurun 98,4 %, dan jumlah leukosit menurun 87,31% dibandingkan dengan kelompok PRC sebelum dicuci. Selain itu, kadar hemoglobin dari komponen darah leukodepleted menurun 29,1%, volume hematokrit meningkat 21%, kadar protein menurun 79,1% dan jumlah leukosit menurun 99,9% dibandingkan dengan kelompok WB sebelum dijadikan komponen leukodepleted PRC. Persentase hemolisis pada komponen darah WE dan LD-PRC adalah < 0,8% Perbedaan bermakna komponen darah WE dan LD-PRC dapat diamati pada parameter penilaian protein sisa dan leukosit sisa (p<0,05). Simpulan. Dalam pembuatan komponen darah WE protein plasma berkurang sebanyak 98,4%, sedangkan dalam pembuatan leukodepleted PRC, jumlah leukosit berkurang sebanyak 99,97%. Terjadinya hemolisis dapat diabaikan karena pada kedua komponen darah, hemolisis terjadi < 0,8%. Jika diperlukan komponen darah dengan kandungan protein plasma yang sedikit dapat digunakan komponen darah WE, sementara itu jika diperlukan komponen darah dengan jumlah leukositnya sedikit dapat digunakan/dipilih komponen darah leukodepleted.

ABSTRACTBackground. Washed erythrocyte (WE) and leukodepleted erythrocyte (LD-PRC) are normally used in clinical transfusion to prevent transfusion reaction. However, clinicians are wondering on the safety of those two blood components. The open system with saline for erythrocyte washing and the use of filter for blood leukodepletion still leave quiries on the possibility of hemolysis and their effectiveness for clinical transfusion. This study aims to provide scientific reasoning and the appropriate use of WE and leukodepleted blood respectively. Methods. A cross sectional approach was employed in this study on two groups of blood component consisting of 52 blood samples each , i.e. WE and LD-PRC respectively. Blood examinations were carried out on 26 WE samples prior to and after washing and on 26 LD-PRC samples prior to and after leukodepletion. Blood indices were examined automatically using Sysmex Xn-2000, total protein was estimated using ADVIA 1650/1800, while blood hemolysis was observed employing Osmotic Fragility Test (OFT). Results. It was shown that hemoglobin concentration of WE group decreased by 15.4%, hematocrit volume decreased by 8.55%, protein concentration decreased by 98.4%, and leukocyte count decreased by 87.3% compared to those the original Packed Red Cells. In addition, it was shown that the hemoglobin concentration of the leucodepleted blood component decreased by 29.1%, hematocrit volume increased by 21%, protein concentrations decreased 79.1% and the leukocyte count decreased by 99.9%. All the sampel of the WE blood products and all the LD-PRC blood sampel has hemolysis level <0,8% However, a significant difference in protein concentration and leukocyte count was observed betwen WE and LD-PRC (p<0.05). Conclusion. The process of erythrocytes? washing decreased the plasma protein concentration by 98.4%, whilst the process of leucodepletion decreased the leucocyte count by 99.97%. Hemolysis during the preparation of both blood components could be negligible. It is concluded that WE blood component is preferable for transfusion when low plasma protein is required. On the other hand, leukodepleted PRC is preferable when blood component with low in leucocyte count is required.;Background.

"ABSTRAKPeningkatan keberhasilan dalam pelayanan kesehatan dan teknologi medis di negaraberkembang termasuk Indonesia yang mengarah ke peningkatan populasi dunia telah diikutioleh peningkatan kebutuhan darah untuk transfusi klinis. Namun, layanan darah di seluruhdunia menghadapi masalah serupa, yaitu kurangnya pasokan darah akibat peningkatanpermintaan, sementara jumlah donor cenderung stabil. Menurut perhitungan WHO, Indonesiamemerlukan darah sekitar 2% dari total populasi yaitu 4,8 juta unit darah per tahun untuk240 juta orang. Partisipasi aktif dan rutin pendonor yang memenuhi syarat sangat diharapkanuntuk memenuhi kualitas yang baik serta darah yang aman. Batasan usia untuk donor darahlansia adalah salah kontributor terjadinya permasalahan kekurangan donor.Sebuah penelitian deskriptif dirancang untuk menguji kelayakan donor darah lansiauntuk memperpanjang sumbangan mereka melampaui batasan usia saat ini. Parameterhematologi yaitu hemoglobin, hematokrit, MCV, MCH, MCHC dan trombosit diukurterhadap dua kelompok pendonor pada UDD DKI, berusia di atas dan di bawah 60 tahun (60-65 tahun dan 17-59 tahun) yang masing-masing terdiri dari 50 subyek penelitian. Dua kalipengukuran hematologi dilakukan pada kedua kelompok saat donor darah pada hari 0 dan 75.Selain itu dilakukan pula pengukuran kontrol dari sampel darah vena pada masing-masingkelompok dilakukan pada hari ke-38Tidak ada perbedaan yang signifikan pada hasil pemeriksaan kedua kelompok.Tingkat pemulihan rata-rata hemoglobin dan paramenters hematologi lainnya untuk keduakelompok donor hampir mendekati bahkan sama dengan level pada hari ke 0 saat donordarah. Sebagai kesimpulan, donor darah lansia terutama pada usia 60 sampai 65 tahun masihpotensial atau memenuhi syarat untuk menjadi donor darah sukarela secara teratur untukmenjaga persediaan darah transfusi yang cukup di Jakarta.Studi lebih lanjut meliputi berbagai lokasi di Indonesia masih diperlukan untukmendapatkan kesimpulan nasional yang lebih akurat

ABSTRACTSuccessful improvement in health services and medical technology in developingcountries including Indonesia leading to the increase in world population has been followedby the increase in the requirement of blood for transfusion clinical practice. However, bloodservices around the world encounter similar problem, namely a lack of blood supply due tothe increase in demands, whilst the number of donors tend to be stable. According to WHOestimation, Indonesia in particular needs approximately 2% of the total population i.e. 4.8million units of blood per year for 240 million people. Active and regular participation ofeligible blood donors are expected to meet the high quality and save blood. Limitation fordonation of elderly blood donors is among contributors for donor shortage.The present descriptive study was designed to examine the eligibility of elderly blooddonors to extend their donation beyond the current age limitation. Hematological parametersi.e. hemoglobin, packed cell volume, MCV, MCH, MCHC and platelet were measured in twogroups of UDD DKI blood donors above and below 60 years of age (60-65 years and 17-59years) consisting of 50 subjects respectively. Twice hematologic measurements were carriedout in both groups during blood donation time on day 0 and 75. In addition once controlmeasurement from venous blood samples of the respective groups was carried out on day 38.No significant different was observed in two groups. Average recovery levels ofhemoglobin and other hematological paramenters for both donor groups almost approachedeven at equal level with level at day 0 of blood donation. In conclusion, elderly blood donorsparticularly in their 60 to 65 years of age were still potential or eligible to be regularvoluntary blood donors to keep sufficient blood donors in Jakarta.Further study encompassing various locations in the country are still required toobtain more accurate nationwide conclusion."

"ABSTRAKDeteksi antibodi bertujuan untuk mendeteksi adanya antibodi ireguler terhadap sel darah merah di dalam plasma pasien. Sampai saat ini, kegiatan pelayanan transfusi darah di Indonesia masih bergantung pada uji silang serasi yang masih kemungkinan adanya antibodi ireguler yang tidak terdeteksi. Antibodi tersebut dapat menyebabkan terjadinya reaksi transfusi tipe lambat yang ditandai dengan penurunan hemoglobin dan peningkatan kadar bilirubin. Upaya keamanan pada pasien transfusi perlu ditingkatkan dengan diterapkan uji saring antibodi secara rutin pada pemeriksaan pra-transfusi. Tujuh ratus sampel pasien yang meminta darah ke laboratorium pelayanan pasien di UTD PMI DKI Jakarta dilakukan uji saring antibodi dan uji silang serasi secara otomatis dengan alat Ortho AutoVue Innova dengan Column Agglutination Technology. Untuk membuktikan kompatibel palsu dipilih 10 plasma pasien yang mengandung antibodi untuk dilakukan uji silang serasi mayor dengan 70 sampel darah donor. Hasil kompatibel dilakukan konfirmasi dengan antigen typing pada donor. Semua sampel pasien yang tidak memiliki antibodi 100 kompatibel pada uji silang serasi mayor. Dari 70 sampel dengan hasil kompatibel pada uji silang serasi mayor ditemukan 14 20 hasil negatif palsu. Dari penelitian ini disimpulkan uji saring antibodi lebih mampu mendeteksi antibodi pada plasma pasien dan aman digunakan dalam pemeriksaan pra-transfusi.

ABSTRACTDetection of antibody aims to detection of irregular antibody on the blood cell in patient plasma. Until now, blood transfusion in Indonesia in terms still depending on the crossmatch is still risking on undetected irregular antibody. The irregular antibody may cause a delayed hemolytic transfusion with hemoglobin reduction and bilirubin increase as the symptoms. Patient with blood transfusion 39 s safety needs to be improved by routine antibody screening on pre transfusiontest. 700 samples of patients who requested blood to the patient care laboratory in UTD PMI DKI Jakarta were antibody screening and major crossmatch automatically with Ortho tool AutoVue Innova with Column Agglutination Technology. To prove false compatible, 10 patient 39 s plasma containing antibodies have been selected to be tested by major of crossmatch with 70 blood donor samples. Compatible Results were confirmed with antigen typing. All samples of patients who did not have antibodies 100 compatible on crossmatch test. from 70 samples which compatible on major crossmatch test was found 14 20 of false negative results. This study suggests the antibody screening which capable of detecting antibodies in the patient 39 s plasma and safely used in the pre transfusion test. "
