"[ABSTRAKLatar belakang. Uji saring darah donor dapat menurunkan risiko tertularnya infeksi HCV. Di Indonesia telah dilakukan uji saring terhadap antibodi HCVdan RNA HCV. Uji saring terhadap Antigen-Antibodi belum dilakukan diIndonesia. Antigen HCV biasanya ditemukan pada 0 sampai 20 hari setelah RNA HCV pertama muncul. Anti-HCV dapat terdeteksi antara 10-40 harisetelah antigen HCV terdeteksi. Atas dasar pemikiran bahwa antigen HCVmuncul didalam darah lebih dahulu daripada anti-HCV, maka penelitian yangdilakukan ingin melihat apakah penggunaan reagensia serologi antigen-antibodi HCV dapat meningkatkan keamanan darah dan apakah sensitivitas serta spesifisitasnya sudah memenuhi standard yang dikeluarkan oleh Kementerian Kesehatan bila dibandingkan terhadap metoda NAT, yaitu sensitivitas 99,8% dan spesifisitas 95%.Metodologi. Pada penelitian ini dilakukan pemeriksaan pada 135 sampel darah donor yang terdiri dari 35 sampel positif dengan NAT HCV dan 100 sampel Positif dengan NAT HCV juga non reaktif terhadap HIV, HBsAg dan Sifilis dengan uji saring anti-HCV dengan metode CMIA, Ab-Ag HCV dengan metode ELISA dan bila ada perbedaan hasil pada pemeriksaan NAT HCV,CMIA HCV dan ELISA Ag-Ab HCV dilakukan pemeriksaan dengan menggunakan imunoblot HCV.Hasil. Dari 135 sampel, pada pemeriksaan ELISA Ag-Ab HCV terhadap 35 sampel positif RNA HCV menunjukkan hasil positif pada 35 sampel tersebut,tetapi pada 100 sampel negatif RNA HCV terdapat 3 sampel reaktif dan 97 nonreaktif. Sedangkan pada 35 sampel positif RNA HCV dengan pemeriksaanCMIA anti-HCV menunjukkan hasil reaktif pada 35 sampel dan pada 100 sampel negatif RNA HCV terdapat 11 sampel reaktif dan 89 sampel non reaktif.Sensitivitas dari perbandingan hasil pemeriksaan metoda NAT HCV dengan CMIA Ab-HCV adalah 100%, spesifisitasnya adalah 89%. Sensitivitas dari perbandingan hasil pemeriksaan metoda NAT HCV dengan ELISA Ag-AbHCV adalah 100%, spesifisitasnya adalah 97%.Simpulan. Pemeriksaan Antigen-Antibodi HCV ELISA memenuhi kriteriastandar untuk digunakan sebagai uji saring darah donor. Pemeriksaan AntibodiHCV CMIA tidak memenuhi kriteria standar untuk digunakan sebagai uji saringdarah donor.

ABSTRACTBackground. Screening of donor blood may reduce the risk of transmission of HCV infection . In Indonesia has be screened for HCV antibodies and HCVRNA . Screened against the antigen - antibody has not been done in Indonesia .HCV antigens commonly found in 0 to 20 days after HCV RNA first appears .Anti - HCV can be detected between 10-40 days after HCV antigen wasdetected . On the basis of the notion that HCV antigens appear in the blood earlier than the anti - HCV , the research done to see if the use of antigen - antibody reagents HCV serology can improve blood safety and whether thesensitivity and specificity already meet the standards issued by the Ministry of Health when compared to NAT method , the sensitivity 99.8 % and specificity of 95 % . Methodology. In this study conducted checks on 135 blood samples from 35 donors comprising the NAT HCV positive samples and 100 samples positive by HCV NAT is also non- reactive to HIV , HBsAg and syphilis with anti - HCVscreening of the CMIA method, HCV Ab-Ag ELISA method and theexamination confirmed using immunoblot HCV HCV . Results. Of the 135 samples, the Ag-Ab ELISA against HCV 35 HCV RNA positive samples showed positive results in 35 samples, but at 100 HCV RNA negative samples contained 3 samples reactive and non- reactive 97.

"ABSTRAKLatar belakang. Pelayanan transfusi darah merupakan penunjang pelayanan kesehatan yang sangat penting, karena hingga saat ini masih terdapat beberapa kondisi kesehatan yang hanya dapat diatasi dengan pemberian transfusi darah. Salah satu strategi World Health Organization (WHO) dalam pelayanan darah yang aman adalah transfusi darah atas indikasi medis secara rasional. Febrile non-haemolytic transfusion reaction (FNHTR) telah dilaporkan sebagai reaksi transfusi yang paling umum terjadi dengan insidensi 6,8% setelah transfusi produk komponen packed red cell (PRC). Data di Pusat Thalassemia Rumah Sakit Dr. Cipto Mangunkusumo (RSCM) Jakarta, dari 73% pasien yang mendapat PRC leucoreduction, 15% di antaranya mengalami reaksi transfusi, sedangkan dari 14% pasien yang mendapat PRC biasa, 65% di antaranya mengalami reaksi transfusi. Di Indonesia, PRC yang tersedia umumnya adalah produk PRC leucoreduction dengan metoda buffy-coat depleted. Penelitian ini bertujuan untuk mengetahui efektifitas penurunan jumlah leukosit dan sitokin pada produk PRC dari metoda buffy-coat depleted dibandingkan dengan metoda modifikasi bed-side leucocyte filtration. Metodologi. Penelitian ini menggunakan desain potong lintang pada subjek berupa 30 produk PRC yang dibuat dengan metoda buffy-coat depleted dan 30 produk PRC yang dibuat dengan metoda modifikasi bed-side leucocyte filtration pada <48 jam masa penyimpanan. Pada semua produk dilakukan pemeriksaan hematologi dan pemeriksaan sitokin pirogen IL-6 dan TNF-α. Hasil. Satu (3,33%) subjek kantong komponen PRC yang dibuat dengan metoda buffy-coat depleted memenuhi standar leukoreduction (<5x108 leukosit/unit), dan 29 (96,7%) subjek kantong komponen PRC yang dibuat dengan metoda modifikasi bed-side leucocyte filtration pada waktu < 48 jam penyimpanan memenuhi standar leukodepleted (<5x106 leukosit/unit). Pada penelitian ini tidak didapatkan perbedaan bermakna kadar IL-6 dan TNF-α pada kedua kelompok komponen PRC ( p > 0,05 ). Simpulan. Terdapat penurunan jumlah leukosit komponen PRC yang dibuat dengan metoda modifikasi bed-side leucocyte filtration pada < 48 jam masa penyimpanan PRC sangat signifikan dibandingkan dengan metoda buffy-coat depleted. Hal ini disebabkan oleh peranan filter polyurethane yang selektif menyaring leukosit sedangkan penurunan jumlah leukosit pada metoda buffy-coat depleted dipengaruhi oleh kecepatan dan waktu putaran sentrifus serta pemisahan lapisan buffy coat dari komponen PRC. Tidak bermaknanya perbedaan kadar sitokin pirogenik IL-6 dan TNF α pada kedua kelompok PRC dikarenakan masa penyimpanan PRC < 48 jam tidak menyebabkan akumulasi sitokin pirogenik IL-6 dan dan TNF-α.

ABSTRACTBackground. Blood transfusion is an essential part of health services, that can safe lifes. One of the World Health Organization (WHO) strategy on safe blood. White blood cells/leukocytes are present in all cellular blood components that are prepared by standard technique. Febrile non-haemolytic transfusion reaction (FNHTR) has been reported as a common transfusion reaction with the incidence of 6,8% after Packed Red Cell (PRC) transfusion. Data in Thalassemia Center DR. Cipto Mangunkusumo Hospital in Jakarta, from 73% of patients who received PRC leucoreduced component, 15% of them had a transfusion reaction, whereas 14% of patients who received PRC component, 65% of them had a transfusion reaction. In Indonesia, the common PRC component available is a leucoreduced PRC developed by buffy-coat depleted method. The study is aim to evaluate the effectiveness of leucocyte reduction and cytokine on the PRC components developed by buffy-coat depleted method compare to the PRC products developed by modified bed-side leucocyte filtration method. Methodology. The study is a cross sectional study on the subject of 30 PRC components developed by buffy-coat depleted method and 30 PRC component developed by modified bed-side leucocyte filtration method in < 48 hour of storage. Haematology testing and pyrogenic cytokine of IL-6 and TNF-α titer was analyzed on all subjects.Result. There was only one (3.33%) subject of PRC developed by buffy-coat depleted method showed to be leucoreduced (<5x108 leucocyte/unit), mean while there was 29 (96,7%) subject of PRC developed by modified bed-side leucocyte filtration method showed to be leukodepleted (<5x106 leucocyte/unit).No significant difference of IL-6 and TNF-α titer on both of PRC components. (p > 0,05 ).Conclusion. Reduction of leucocyte on the PRC components developed by modified bed-side leucocyte filtration is more effective compare to that on the PRC components developed by buffy-coat depleted method. The adhesion principle of leucocyte into polyurethane filter was more effective in reducing the number of leucocyte compare to centrifugation principle. The leucocyte filtration that was run on the PRC components with the storage time of < 48 hour did not caused the accumulation of pyrogenic cytokine such as IL-6 and TNF-α."
