"Currently, we reported results of a nested polymerase chain reaction (PCR) assay specific 5` untranslated region (UTR) region of hepatitis C virus (HCV) genome that showed three different patterns of deoxyribonucleic acid (DNA) fragments (single expected specific DNA band, single DNA band higher in size than an expected band, and multiple DNA bands). Three isolates (Isolate A, B, and C), representing all the three DNA bands, were analyzed by using phylogenetic trees. The results showed that the Isolate A, B, and C were classified into HCV genotypes 2, 1, and 3, respectively. The Isolate A and B were very closely related to viral isolates from Madagascar and Brazil, respectively and were not closely related to other Indonesia isolates. In contrast with the Isolate A and B, the Isolate C was very closely related to another Indonesia isolate. Among all there isolates, the Isolate C was very closely related to an Indonesia isolate detected from a cirrhosis patient, indicating that the Isolate C might be more virulence than the Isolate B and C. However, a complete genome-based comprehensive genetic characterization for all the three isolates needs to be conducted in future research to confirm all findings in this study."

"Chronic hepatitis C virus : lessons from the past, promise for the future documents the monumental advances that have been made in our understanding of chronic HCV during the past decade. The first section reviews the natural history of chronic HCV, how this virus can affect other organs in addition to the liver, and whether treating chronic HCV alters the natural history of this disease. Section 2 reviews the advances that have been made in the treatment of chronic HCV during the past decade with interferon based therapy. Separate chapters on response guided therapy and how to manage the adverse events associated with these medications provide the physician with the concepts required to more effectively treat chronic HCV now and in the future. As the genetics of virologic response have recently been elucidated, a chapter is devoted to helping the clinician understand how genes that modulate disease processes and their treatment are identified and utilized in clinical care. Section 3 deals with the future of HCV treatment and specific inhibitors of HCV. Specific chapters explain how targets for drugs are identified and how drugs are then developed and tested; how mutations of HCV develop and how anti-viral agents will affect this process; the most up to date data regarding the treatment of chronic HCV with peginterferon, ribavirin and anti-viral agents; and the potential to treat chronic HCV with just oral anti-viral agents and without peginterferon and ribavirin in the future. The final section of this book covers issues related to liver transplantation in patients with chronic HCV. Separate chapters review the natural history of chronic HCV in liver transplant recipients and the impact of utilizing HCV positive donors. The volume concludes with chapters that cover the treatment of chronic HCV both prior to and after liver transplantation with potent anti-viral agents. Chronic hepatitis C virus : lessons from the past, promise for the future is a valuable resource for all physicians caring for patients with chronic HCV."

"Karsinoma hepatoseluler (KHS) adalah salah satu kanker dengan laju mortalitas tertinggi di dunia. Kadar serum alfa-fetoprotein (AFP) dapat digunakan sebagai biomarker untuk menegakkan diagnosis dini. Tetapi, perbandingan antara kadar serum AFP dan KHS dengan etiologi infeksi virus dan etiologi non infeksi virus belum diketahui. Mengetahui perbandingan antara kadar serum AFP dan KHS dengan etiologi infeksi virus dan etiologi non infeksi virus. Penelitian potong lintang dilakukan di RSUPN Cipto Mangunkusumo, Jakarta pada Januari-Oktober 2018 dengan melihat data rekam medis dari 287 pasien yang terdiagnosis KHS dalam periode 2013-2017. Nilai median (minimum-maksimum) dari kadar AFP pada pasien KHS dengan etiologi infeksi VHB atau VHC adalah 419 (0.8-400.000). Nilai median (minimum-maksimum) kadar AFP pada pasien KHS dengan etiologi non infeksi VHB-VHC adalah 7.18 (0.6-90.944). Terdapat perbedaan bermakna antara kadar AFP dengan KHS dengan etiologi infeksi VHB atau VHC dan etiologi non infeksi VHB-VHC.

Hepatocellular carcinoma (HCC) is one of the highest rates of mortality in the world. Serum alpha-fetoprotein (AFP) levels can be used as a biomarker for early diagnosis. However, the comparison between serum AFP and HCC with viral infections etiology and non-viral etiology is unknown. This research aims to determine the comparison between serum AFP and HCC with viral infections etiology and non-viral aetiology. A cross-sectional study conducted in Cipto Mangunkusumo Hospital, Jakarta in January to October 2018 by reviewing 287 medical records of patients diagnosed with HCC from 2013-2017 period of time. The median (minimum-maximum) value of AFP levels in HCC patients with the etiology of HBV or HCV infection is 419 (0.8-400,000). The median value (minimum-maximum) of AFP levels in HCC patients with the etiology of non HBV-HCV infection was 7.18 (0.6-90,944). There were significant differences between AFP levels and KHS with the etiology of HBV or HCV infections and the etiology of non HBV-HCV infections."

"ABSTRAK<

Karsinoma hepatoseluler (KHS) merupakan karsinoma primer tersering pada sel hati. Sebagian besar KHS disebabkan oleh virus hepatitis B (VHB) dan virus hepatitis C (VHC) yang memiliki patogenesis yang berbeda dalam menyebabkan KHS. Alfa-fetoprotein (AFP) sebagai penanda tumor pada KHS dan dipengaruhi oleh berbagai faktor, salah satunya status infeksi. Berbagai penelitian sudah dilakukan untuk mengetahui pengaruh pengaruh jenis virus penyebab KHS dengan kadar AFP namun hasilnya sangat beragam. Berdasarkan hal tersebut dan ditambah dengan belum adanya penelitian serupa yang menggunakan data pasien di Indonesia maka penelitian ini bertujuan untuk membandingkan kadar AFP pada pasien KHS terkait infeksi VHB terhadap VHC. Penelitian ini dilakukan dengan desain studi potong lintang menggunakan 199 data AFP pasien KHS yang terdiri dari 129 kasus KHS terkait VHB dan 70 kasus KHS terkait VHC. Dari penelitian ini didapatkan sebanyak 97% dan 87.3% pasien KHS terkait VHC dan VHB mengalami peningkatan kadar AFP secara berurutan. Nilai median kadar AFP pada pasien KHS terkait VHB adalah 419 IU/mL sedangkan pada pasien KHS terkait VHC sebesar 400 IU/mL. Perbedaan nilai tersebut memiliki nilai p = 0.97 dalam uji Mann-Whitney U sehingga disimpulan tidak ada perbedaan bermakna pada rerata kadar AFP antara pasien KHS terkait VHB dibanding dengan VHC.

ABSTRACT

Hepatocellular carcinoma (HCC) is the most primary common carcinoma in liver cells. Most HCC are caused by the hepatitis B virus and hepatitis C that have different pathogenesis in causing carcinoma. Alpha-fetoprotein as tumor marker in HCC is influenced by various factors, one of which is infection status. Various studies have been carried out to determine the influence of the types of viruses causing HCC with AFP levels but the results are very diverse. Based on this and coupled with the absence of similar studies using patient data in Indonesia, this study aims to compare AFP levels in HCC patients related to HBV and HCV. Using cross-sectional design, this study included 199 data of AFP in patient with HCC comprises of 129 cases of HCC related to HBV and 70 cases of HCC related to HCV. From this study, it was found that 97% and 87.3% of HCC patients related to HCV and HBV experienced an increase in AFP levels consecutively. The median value of AFP levels in HBV-related HCC patients was 419 IU / mL while in HCV-related HCC patients was 400 IU / mL. The difference in value has a p value = 0.97 in the Mann-Whitney U test thus it is concluded that there is no significant difference in AFP levels between HBV-related HCC patients compared with HCV-related HCC.

Makalah ini adalah laporan hasil pengujian genomHCV dengan metode nested PCR 5` UTR spesifik yang menunjukkan adanya tiga pola fragmen DNA yang berbeda(untai DNA spesifik yang diekspektasi tunggal, untai DNA tunggal yang berukuran lebih tinggi daripada untai yangdiekspektasi, dan untai DNA majemuk). Tiga isolat (Isolat A, B, dan C) yang mewakili tiga berkas DNA itu dianalisisdengan pohon filogenetik. Hasil penelitian menunjukkan bahwa Isolat A, B, dan C tergolong genotipe HCV 2, 1, dan 3secara berturut-turut. Isolat A dan B masing-masing berhubungan erat dengan isolat virus dari Madagaskar dan Brazil,meskipun keduanya tidak berhubungan erat dengan isolat dari Indonesia. Berbeda dengan isolat A dan B, Isolat Cberhubungan erat dengan isolat dari Indonesia. Di antara ketiga isolat, Isolat C memiliki hubungan paling erat denganisolat Indonesia yang ditemukan pada seorang pasien kirosis. Hal ini menunjukkan adanya kemungkinan bahwa Isolat Clebih berbahaya daripada Isolat B dan C. Bagaimanapun, karakterisasi genetis komprehensif berbasis genom yanglengkap terhadap ketiga isolat perlu dilaksanakan pada kajian-kajian berikutnya untuk mendukung hasil penelitian ini."
