"Chronic hepatitis due to hepatitis B virus (HBV) or hepatitis C virus (HCP) is still a major problem in terms of progressive liver damage, prevention and therapy in most parts ofthe world. Unfortunately, to date, there is still no specific and effective therapy for HBV. No therapy can be given to carrier; non-replicative and asymptomatic patients of chronic HBV infection. Lamivudine or alpha-interferon can be used for treatment of compensated chronic hepatitis B infection with significant increase of aminotransferase. Approximately 40 % of patients can have seroconversion with this form of therapy. Chronic hepatitis D virus injection can be treat with alpha-interferon and in the final stage, may undergo liver transplantation. For chronic hepatitis C virus infection, alpha-interferon with ribavirin have been shown to have a better efficacy than afpha-interferon alone where the efficacy can reach 39-49 %."

"Latar Belakang : Wabah pneumonia akibat Corona Disesase 2019 (COVID-19) masih menjadi perhatian nasional maupun global. Wanita hamil termasuk dalam kelompok risiko tinggi/rentan terhadap infeksi COVID-19. Adanya badai sitokin akibat infeksi COVID-19 menyebabkan gejala klinis yang semakin berat. Zinc sebagai salah satu mikronutrien penting yang berpengaruh dalam regulasi produksi sitokin oleh sistem imun tubuh. Kondisi defisiensi zinc pada wanita hamil yang terinfeksi COVID-19 dapat menyebabkan disregulasi dari sistem imun dan menghasilkan badai sitokin yang mengakibatkan sindrom ancaman gagal napas akut dan kematian. Tujuan : Meneliti hubungan kadar zinc serum maternal terhadap kadar sitokin pro- inflamasi interleukin-6 (IL-6) dan interferon gamma (IFN-) pada wanita hamil yang terkonfirmasi COVID-19 dengan gejala ringan-sedang dan berat. Metode : Penelitian observasional dengan desain studi cross-sectional. Subyek penelitian adalah wanita hamil yang terkonfirmasi COVID-19 dengan gejala ringan-sedang dan berat. Faktor yang diteliti meliputi kadar zinc, IL-6 dan IFN- serum maternal dan hubungannya kadar zinc serum terhadap kadar IL-6 dan IFN- serum maternal.Hasil : Jumlah total subyek sebanyak 48 orang dibagi menjadi 28 subyek untuk kelompok wanita hamil yang terkonfrimasi COVID-19 gejala ringan-sedang dan 20 subyek dengan gejala berat. Rata-rata usia responden 30,61 tahun untuk kelompok gejala ringan-sedang dan 32,9 tahun untuk kelompok gejala berat. Rata-rata usia kehamilan pada kelompok gejala ringan-sedang lebih tua dibanding kelompok gejala berat (38,1 minggu vs 34,5 minggu).Lama perawatan kelompok dengan gejala berat lebih lama dibanding kelompok gejala ringan-sedang. 60% subyek dari kelompok gejala berat berakhir dengan kematian maternal. Semua subyek dalam penelitian ini mengalami defisiensi zinc. Tidak terdapat perbedaan bermakna kadar zinc serum maternal pada kedua kelompok yaitu 54,0 (34-78) μg/dl untuk kelompok gejala ringan-sedang dan 52,0 (38-97) μg/dl untuk kelompok gejala berat. Terdapat perbedaan bermakna antara kelompok gejala ringan-sedang dengan kelompok gejala berat terhadap kadar IL-6 serum (5,8 (1,5-69,6) pg/ml vs 18,6 (3,8-85,3) pg/ml) dan kadar IFN- serum (0,9 (0,1-16,8) pg/ml vs 9,0 (0,9-21,1) pg/ml). Tidak ada korelasi antara kadar zinc serum maternal dengan kadar IL-6 dan IFN- serum maternal. Kesimpulan : Kadar zinc serum maternal tidak berbeda bermakna diantara kedua kelompok penelitan. Kadar IL-6 dan IFN- serum kelompok gejala berat lebih tinggi dibanding kelompok gejala ringan-sedang. Tidak ada korelasi antara kadar zinc serum dengan kadar IL-6 dan IFN- serum maternal.

Bacground : The outbreak of Corona Disesase 2019 (COVID-19) is still a national and global concern. Pregnant women are included in the highrisk/susceptibility group for COVID-19 infection. The presence of a cytokine storm due to COVID-19 infection causes increasingly severe clinical symptoms. Zinc is one of the important micronutrients that influence the regulation of cytokine production by the immune system. Zinc deficiency in pregnant women with confirmed COVID-19 can cause dysregulation of the immune system and produce a cytokine storm that results in acute respiratory distress syndrome and maternal death. Objective: To evaluate the relationship between maternal serum zinc levels and the pro- inflammatory cytokines interleukin-6 (IL-6) and interferon-gamma (IFN-) in pregnant women with confirmed COVID-19 with mild-moderate and severe symptoms. Methods: A cross-sectional was adopted in this study. The subjects of the study were pregnant women with confirmed COVID-19 with mild-moderate and severe symptoms. We measure the maternal serum zinc levels, serum IL-6 and IFN- levels, then we evaluate the relation between the maternal serum zinc levels and the maternal serum IL- 6 and IFN- levels.

Results: The total number of subjects was 48 patiens, divided into 28 subjects for the pregnant women with confirmed COVID-19 with mild-moderate symptoms and 20 subjects with severe symptoms. The average age of the respondents was 30.61 years for the mild-moderate group and 32.9 years for the severe group. The mean gestational age in the mild-moderate group was older than in the severe one (38.1 weeks vs. 34.5 weeks). The length of stay of subjects with severe symptom was longer than the mild-moderate group. 60% cases from the severe group ended in maternal death. All the participants in this study suffered zinc deficiency. There was no significant difference in maternal serum zinc levels between the two study groups (54.0 (34-78) g/dl in mild-moderate group vs 52.0 (38-97) g/dl in severe group). There was a significant difference between mild- moderate vs severe groups in which the serum IL-6 levels were (5.8 (1.5-69.6) pg/ml vs 18.6 (3.8-85.3) pg/ ml) and the serum IFN- levels were (0.9 (0.1-16.8) pg/ml vs. 9.0 (0.9- 21.1) pg/ml). There is no correlation between maternal serum zinc level and maternal serum IL-6 and IFN- levels. Conclusion: The maternal serum zinc levels were not significantly different between the two study groups. The maternal serum IL-6 and IFN- levels in the severe group were higher than in the mild-moderate group. There is no correlation between maternal serum zinc level and maternal serum IL-6 and IFN- levels."

"Chronic hepatotropic viruses commonly evade the antiviral defence systems of the body and cause a long - lasting persistent infection. The prolonged nature of the infection ensures that every infected person has ample opportunity to transmit the virus to others, allowing many millions of people world-wide to become infected. Three viruses commonly cause chronic hepatitis B virus, hepatitis C virus and hepatitis Delta virus.Virus specific CD8 T cells of the host, represent the main effector cells against viral infection. Where as the antiviral cytokinex have a major role in the control of viral replication (non-cytolytic inhibition).To cause persistent infection, a virus must avoid the host defences and that hepatotropic viruses have developed elaborate strategies to achieve this. In the case of hepatitis B virus, two proteins are involved in the inhibition of the host defences; those are the core protein that has been shown to inhibit the production of interferon and the polymerase protein has been shown to inhibit its effect. Where as in the case of hepatitis C virus, the NS5A and E2 protein reduce the effect of interferon by inhibiting the antiviral kinase.In order to survive and persistent in the liver, the hepatotropic viruses must be able to avoid both arms of the immune system, either by mutation of viral proteins or by preventing activation of the immune system."

"Ruang lingkup dan metodologi: Glukokortikoid telah lama digunakan sebagai antiiflamasi dan imunosuppresan. Penggunaan yang panjang dengan dosis tinggi menyebabkan efek samping yang cukup serius. Dewasa ini telah dikembangkan berbagai pembawa obat yang dapat membawa obat langsung ke target obat atau ke reseptornya. Dengan menginkorporasikan obat ke pembawa obat, contohnya liposom, efek samping sistemik dapat ditekan. Purwaningsih dkk telah berhasil membuat sediaan baru yakni Liposom-metilprednisolon palmitat (L-MPLP). Penelitian ini bertujuan untuk mempelajari efek farmakologi dari L-MPLP, terutama efek antiinflamasinya. Parameter yang dilihat adalah penurunan produksi interferon gamma pada kultur limfosit T setelah distimulasi dengan concanavalin A secara in vitro maupun in vivo. Hasil dan Kesimpulan : Terjadi penurunan kadar interferon gamma setelah pemberian L-MPLP secara in vivo pada dosis 2, 8 dan 16 mg/kgBB secara signifikan dibandingkan kontrol tanpa perlakuan sedangkan pemberian MPL tidak terjadi penurunan kadar interferon gamma. Pada kultur in vitro, pemberian L-MPLP maupun MPL pada kadar 5.10 -1, 5.10-2 dan 5.10-3 keduanya mampu menekan produksi interferon gamma, dimana penekanan oleh L-MPLP lebih baik dibanding MPL secara signifikan.

The Improving of Methylprednisolone Palmitate Potency After Incorporated With Liposome. An Antiinflammation Study In Culture Of Mice?s Splenocytes. Glucocorticoid has been used as an antiinflammatory and immuno-suppresive drug. Longterm utilisation at high dose of glucocorticoid is associated with serious side effects. In recent years, many attempts have been performed in searching the appropiate vehicles to deliver the drug directly into the target organ or the receptor. By incorporating the drug into its vehicle such as liposome, the systemic side effect can be minimized. Purwaningsih et al has successfully synthetized a novel preparation of liposome methylprednisolone palmitate (L-MPLP). The aim of the study was to learn the pharmacological effect of L-MPLP, especially on antiinflammatory effect of this novel preparation, compared with the standard methylprednisolone (MPL). The parameter was the potency of L-MPLP in reducing gamma-interferon production in T-lymphocyte culture after stimulation with concanavalin A in vitro as well as in vivo. Gamma-interferon was assayed by ELISA method. The reduction of gamma interferon, in vivo, after the administration of L-MPLP at the dose of 2,8 and 16 mg/kgBW respectively, showed significant difference than a control group, while MPL did not. The addition of both L-MPLP and MPL in in vitro culture at the concentration of 5.10-3, 5.10-2 and 5.10-1 mM have proved to suppress the gamma-interferon production, where the suppression of L-MPLP was more effective than MPL, significantly."

"Infeksi virus hepatitis B (VHB) merupakan masalah kesehatan global. Terapi yang ada saat ini hanya berdampak minimal terhadap covalently closed circular deoxyribonucleic acid (cccDNA), sehingga eradikasi sulit dicapai. Matriks Metaloproteinase-9 (MMP-9) berperan dalam meningkatkan replikasi VHB, namun belum ada penelitian yang mengevaluasi peran penghambat MMP-9 terhadap replikasi VHB. Kultur primer hepatosit diperoleh dari Tupaia javanica dan diinfeksi dengan VHB manusia, kemudian dibagi menjadi dua kelompok, yaitu kontrol dan intervensi. Kelompok intervensi diberikan penghambat MMP-9 dosis 1 nM, 3 nM, dan 7 nM. Peripheral blood mononuclear cells (PBMC) manusia diperoleh dari pasien hepatitis B kronik, kemudian dibagi menjadi dua kelompok, yaitu kontrol dan intervensi. Kelompok intervensi diberikan penghambat MMP-9 dosis 3 nM. Dilakukan pengukuran HBsAg, DNA VHB, cccDNA, MMP-9, type-1 IFN receptor 1 (IFNAR1), dan interferon-β (IFN-β) sebelum dan 72 jam setelah pemberian intervensi pada kedua kelompok. Pada kultur primer hepatosit T. javanica yang diinfeksi VHB manusia, pemberian penghambat MMP-9 dosis 1 nM, 3 nM, dan 7 nM secara konsisten menurunkan kadar HBsAg, DNA VHB, cccDNA, dan MMP-9. Dosis 3 nM meningkatkan kadar IFNAR1, sedangkan dosis 7 nM meningkatkan kadar IFN-β. Dosis 3 nM menunjukkan efek yang lebih optimal dibandingkan dosis lainnya. Pada PBMC manusia dengan infeksi VHB, pemberian penghambat MMP- 9 dosis 3 nM menurunkan kadar HBsAg, DNA VHB, cccDNA, dan MMP- 9, serta meningkatkan kadar IFN-β, namun menurunkan kadar IFNAR1. Studi ini menunjukkan bahwa pemberian penghambat MMP-9 dapat menurunkan kadar HBsAg, DNA VHB, cccDNA, dan MMP-9, serta meningkatkan kadar IFN-β pada kultur primer hepatosit T. javanica dan PBMC manusia.

Hepatitis B virus (HBV) infection remains a significant global health concern. Current therapies have minimal impact on covalently closed circular deoxyribonucleic acid (cccDNA), making HBV eradication difficult. Matrix Metalloproteinase-9 (MMP-9) enhance HBV replication, but its inhibition has not been studied. Primary hepatocyte cultures were obtained from Tupaia javanica and infected with human HBV, then divided into control and intervention groups. The intervention groups were treated with MMP-9 inhibitors at doses of 1 nM, 3 nM, and 7 nM. Human peripheral blood mononuclear cells (PBMC) were isolated from chronic hepatitis B patients and divided into control and intervention groups. The intervention groups received MMP-9 inhibitors at dose of 3 nM. Measurements of HBsAg, HBV DNA, cccDNA, MMP-9, type-1 IFN receptor 1 (IFNAR1), and interferon-β (IFN-β) were performed before and 72 hours after intervention in both groups. In T. javanica primary hepatocyte culture infected with human HBV, MMP-9 inhibitors at doses of 1 nM, 3 nM, and 7 nM consistently decreased levels of HBsAg, HBV DNA, cccDNA, and MMP-9. The 3 nM dose increased IFNAR1 levels, while the 7 nM dose increased IFN-β levels. The 3 nM dose demonstrated the most optimal effects. In human PBMC with HBV infection, MMP-9 inhibitor at dose of 3 nM decreased levels of HBsAg, HBV DNA, cccDNA, MMP-9, increased IFN-β levels, but reduced IFNAR1 levels. This study shows that administration of MMP-9 inhibitors reduced levels of HBsAg, HBV DNA, cccDNA, and MMP-9, while increased IFN-β levels in T. javanica primary hepatocyte cultures and human PBMC."
