Abstract

Smoking has become general habits in social life. One popular kind is filtered cigarette. As the base component is tobacco without clove and separated by the filter on it. Long irritation from heat and a toxic component of cigarette changed in oral mucosa epithelial. This condition can stimulate the increase of progenitor cells, which is marked by immunohistochemistry staining method of cytokeratin 19. This descriptive study is to find the expression of cytokeratin 19 in oral mucosa cytoplasm epithelial of filter cigarette smokers. There were 30 smokers which were selected with certain criteria. Samples were taken from a cytological smear of mucosa epithelial then stained with immunohistochemistry method. Analysis has taken by calculating the number of cells in the cytological smear. Then the immunoexpression of cytokeratin 19 was known from the percentage of cytoplasm cells which have brown colour compared with a total number of cells. In conclusion, the smoking filter cigarette would increase the number of progenitor cells from chronic inflammation, which is marked by cytokeratin 19 expression in oral mucosa cytoplasm epithelial of smokers.

Abstract

Pendahuluan: Metastasis merupakan salah satu sifat kanker yang dapat terjadi melalui berbagai cara yaitu melalui rongga tubuh, melalui pembuluh limfatik, dan melalui pembuluh darah (1,2). Pembuluh limfatik merupakan jalur penting dalam metastasis kanker karena sel kanker yang lepas dari kanker primernya dapat berjalan melalui pembuluh limfatik dan menuju nodus limfatikus untuk memasuki pembuluh vena serta menyebabkan metastasis ke organ sekitar. Studi pustaka ini bertujuan untuk menelaah limfangiongenesis sebagai alternative metastasis kanker. Metode: Artikel ini dikumpulkan dengan memanfaatkan pencarian di database jurnal kesehatan bereputasi internasional menggunakan kata kunci metastasis, lymphangiogenesis, lymphatic vessel, VEGFR-3 dari pencarian tersebut ditemukan 27 artikel yang dapat digunakan dalam penulisan sistematik review. Simpulan: Limfangiogenesis dapat terjadi pada kanker melalui interaksi antara VEGF-C dan VEGF-D yang dihasilkan oleh kanker ataupun oleh makrofag dengan reseptornya VEGFR-3 yang terdapat pada endotel pembuluh limfatik yang ada. Limfangiogenesis pada kanker akan menambah jalur metastasis sel kanker menuju pembuluh limfatik. ABSTRACTIntroduction: Metastasis is one of the characteristics of cancer that can occur through various ways, namely through the body cavity, through lymphatic vessels, and through blood vessels (1,2). Lymphatic vessels are an important pathway in cancer metastasis because cancer cells that are released from the primary cancer can travel through the lymphatic vessels and into the lymph nodes to enter the veins and cause metastasis to the surrounding organs. This literature study aims to examine limfangiongenesis as an alternative metastatic cancer. Methods: This article was collected using a search in a database of international reputable health journals using the keyword metastasis, lymphangiogenesis, lymphatic vessel, VEGFR-3 from the search, found 27 articles that could be used in systematic review reviews. Conclusion: Lymphangiogenesis can occur in cancer through the interaction between VEGF-C and VEGF-D produced by cancer or by macrophages with its receptor VEGFR-3 found in the existing lymphatic vessel endothelium. Lymphangiogenesis in cancer will increase the metastatic pathway of cancer cells to lymphatic vessels.Keywords: Metastasis, lymphangiogenesis, lymphatic vessel, VEGFR-3.

Abstract

Cytomegalovirus (CMV) is one of the most common opportunistic viruses in human immunodeficiency virus (HIV)-infected patients. The aim of this study was to determine the CMV seroprevalence among HIV-infected patients and investigate the correlation between the CMV immunoglobulin G (IgG) antibody titers and cluster of differentiation 4 (CD4) T-cell counts, as well as highly active antiretroviral therapy (HAART) use. Serum samples from 69 HIV-infected patients and 65 HIV-seronegative persons attending Dr. Hasan Sadikin General Hospital Bandung in March–June 2012 were examined to detect CMV IgG antibody using electrochemiluminescence immunoassay (ECLIA). Data were analyzed using chi-square test, t-tests and analysis of variance (ANOVA). The results show that there were no statistically significant differences in the seroprevalence of CMV between HIV-infected (97%) and HIV-seronegative persons (94%). The mean of CMV IgG antibodies titers in HIV-infected patients (335.39+174.87 U/mL) were significantly higher than that of HIV-seronegative persons (240.59+192.76 U/mL). There was no significant correlation between CMV IgG antibody titers and CD4 T-cell counts (the mean was 393.58+209.22 cells/mm3). The titers of CMV IgG antibodies were significantly inversely associated with HAART use. The mean of CMV IgG antibody titers in HIV-infected patients on HAART (335.41+172.98 U/mL) were significantly higher than patients without HAART (204.8+213.91 U/mL). In conclusions, this study confirms a high seroprevalence of CMV among HIV-infected patients. High titers of CMV are inversely associated with HAART use while no correlation with CD4 T-cell counts was found.

Tujuan penelitian ini untuk mengetahui seroprevalensi CMV pada pasien HIV dan meneliti korelasi antara titer antibodi imunoglobulin G (IgG) CMV dan jumlah sel-T cluster diferensiasi 4 (CD4) serta penggunaan highly active antiretroviral therapy (HAART). Sampel serum dari 69 pasien HIV dan 65 HIVseronegatif yang berkunjung ke Rumah Sakit Dr. Hasan Sadikin Bandung pada bulan Maret–Juni 2012 diperiksa untuk mendeteksi antibodi IgG CMV dengan immunoassay electro chemiluminescence (ECLIA). Data dianalisis dengan menggunakan uji chi-kuadrat, t, dan analysis of variance (ANOVA). Hasil penelitian menunjukkan tidak ada perbedaan yang signifikan antara seroprevalensi CMV pada pasien HIV (97%) dan HIV-seronegatif (94%). Titer antibodi rata-rata IgG CMV pasien HIV (335,39+174,87 U/mL) signifikan lebih tinggi daripada HIV-seronegatif (240,59+192,76 U/mL). Tidak ada hubungan yang signifikan antara titer antibodi IgG CMV dan jumlah sel-T CD4 (rata-rata 393,58+209,22 sel/mm3). Titer antibodi IgG CMV secara signifikan berhubungan terbalik dengan penggunaan HAART. Titer antibodi IgG CMV rata-rata pasien HIV dengan HAART (335,41+172,98 U/mL) signifikan lebih tinggi dibandingkan dengan pasien tanpa HAART (204,8+213,91 U/mL). Simpulan, penelitian ini menegaskan seroprevalensi CMV pasien HIV dan titer antibodi IgG CMV yang tinggi berhubungan terbalik dengan penggunaan HAART tetapi tidak berkorelasi dengan sel-T CD4.
