Abstract

Background: The Hepatitis B Virus (HBV) pre-S1, pre-S2, and S region are essentially known for virus infection and replication. Eight genotypes (A to H) and nine subtypes (adw2, adw4, ayw1, ayw2, ayw3, ayw4, adrq+, adrq-, and ayr) of HBV have been identified worldwide. The aim of this study was to analyze HBV genetic variation in pre-S1, pre-S2, and S region, and to determine genotype and subtype of 09IDSKAB-3 HBV isolate from Men Who Have Sex With Men community in Surakarta. Methods: 09IDSAKAB-3 HBV DNA extraction was used as a template for amplication of pre-S1, pre-S2, and S region. The sequence results were then aligned by Clustal W with all of reference sequences reported in GenBank/DDBJ/EMNL. Genetic variation in pre-S1, pre-S2, and S region were identified using MEGA 4.0. HBV genotype and subgenotype were identified by phylogenetic analysis. HBV subtype was deduced on the basis of the predicted amino acid sequences of HBsAg. Results: Based on BLAST search in GenBank, 09IDSKAB-3 isolate was classified into genotype B3. D27E variation was found in pre-S1 region, and there were not genetic variation in pre-S2 and S region. Phylogenetic tree showed that 09IDSKAB-3 isolate was classified into genotype B3. Based on the basis of predicted amino acid sequences of HBsAg, 09IDSKAB-3 isolate was classified into subtype adw2. Conclusions: Overall, only D27E variation was found in this study. 09IDSKAB-3 isolate was classified into genoytpe B3 and subtype adw2. The amino acid variations found in the present report need further study. Keywords: HBV, pre-S1 region, pre-S2 region, S region

Abstract

Background: HBV replicates its DNA genome through reverse transcription from RNA intermediate. It is vulnerable to a high number of mutations during such reverse transcription which are frequently found in core promoter and precore/core regions. This study was aimed to identify genetic variation of HBV core promoter and  precore/core regions of 09IDSKAB-3 isolate. Methods: DNA extraction was performed on 09IDSKAB-3 blood sample that was taken from Man Sex with Man Community. Core promoter and precore/core regions were determined by PCR using KL-28 and KL-6 primers and direct sequencing of the corresponding region. Molecular analysis was performed using MEGA 4.0. Results: Based on BLAST result, 09IDSKAB-3 HBV isolate had the highest similarity to isolate AP011085 from DKI Jakarta. Genetic variations A1726C in core promoter, and T1860C, C1877T, G1957C in precore/core region were found in 09IDSKAB-3 isolate. Conclusions: 09IDSKAB-3 HBV isolate was classified into genotype B and subgenotype B3 based on core promoter and precore/core region. The genetic variations found in this isolate may have influence to the replication efficiency and HBeAg/HBcAg production, therefore need further study. Keywords: hepatitis B virus, molecular analysis, core promoter region, precore/core region

Abstract

Background: One problem in HIV treatment is HBV/HCV co-infection due to their similarity in the transmission routes. HBV/HCV co-infection is believed increasing the risk of hepatotoxicity, hepatocellular carcinoma, steatosis, fibrosis, and also rapidly lead to AIDS in the HIV patients. The purpose of this study was to find out the status of HBV/HCV co-infection among HIV patients in Surakarta. Methods: In November-December 2011 all of HIV patients (n=65) visited the Voluntary Counseling and Testing in Moewardi General Hospital Surakarta were involved in the study. Clinical data and blood samples were retrieved from all patients. Serological assays to detect the presentation of HBsAg and anti-HCV were performed in all samples. Results: There were 17% (11/65) HIV patients infected with the hepatitis viruses. Six point two percent (4/65) was HBsAg+, 10.8% (7/65) was anti-HCV+, and 0% with triple infection. There were 57.1% (4/7) females and 42.8% (3/7) males detected with anti-HCV+. Males and females, each was found 50% (2/4) in HBsAg+. Ninety one percent (10/11)HIV patients with both HBV or HCV co-infection were under 50 years old .None of routine blood test was significant with HBsAg+ or anti-HCV+. Conclusions: Several HIV patients had co-infection with Hepatitis B Virus and Hepatitis C Virus, and most of them were females under 30 years. HIV patients should be checked the status of HBV and HCV co-infection in order to have a better therapeutic management. Keywords: HIV co-infection, Hepatitis B Virus, Hepatitis C Virus

Abstract

Background:HIV infection on human can get inhibition from intrinsic factor. Human can produce antivirus protein which is encoded by APOBEC3 gene. APOBEC3B (A3B) is one of APOBEC3 protein, which cannot be degradated by HIV vif protein. Therefore A3B protein is a potent inhibitor of HIV replication. But, A3B gene can get a deletion, which can decrease its effect in inhibiting HIV infection.The aim of this study was to find correlation between CD4 cells count in A3B gene deletion-positive respondents and A3B gene deletion-negative respondents. Methods: There were 51 HIV patients in Dr. Moewardi General Hospital Surakarta on November 2011, which were included as our respondents. We take respondents’s blood and were isolated their DNA. Then, we run in PCR with deletion primer (Deletion_F dan Deletion_R) to detect if there was a deletion in A3B gene sequence. We run electrophoresis in 1% agarose gel with Loading Quick ФX174/HaeIII 72-1353bp as a marker. Then, we visualized the gel on Gel Documentation and was interpreted. Data of A3B gene deletion, respondents’s description, HIV RNA detection, and CD4 cell count were analysed with Chi Square. Results:About 36 respondents (70.6%) were positive for deletion in A3B gene. Four of them were positive for HIV RNA detection. The average of CD4 cells count in respondents, who were positive for A3B gene deletion, was 426.86 ± 407.4 cells/µl and the others were 496.93 ± 573.0 cells/µl (p = 0.782). There were no correlation (p > 0.050) between A3B gene deletion in female respondents and CD4 cells count. A3B gene deletion was more likely to be found in female respondents (OR = 2.286; 95% CI : 0.669 – 7.808). Conclusions:There were no differences between the average of CD4 cell counts in A3B gene deletion-positive respondents and A3B gene deletion-negative respondents.

Abstract

Background: Epidemiological data of GB Virus-C (GBV-C) in Indonesia are limited. Information about GBV-C coinfection among HIV patients in Dr. Moewardi General Hospital in Surakarta has also been unknown. Thus, this study is aimed to know the status of GBV-C coinfection among HIV patients in Dr. Moewardi General Hospital in Surakarta. Methods: Blood samples from 44 HIV patients in Dr. Moewardi General Hospital were subjected to viral RNA isolation. Complementary DNA (cDNA) was synthesized from the isolated RNA and used as template for nested polymerase chain reaction (PCR) detecting the 5-non-translated region of GBV-C. The amplicons were electrophoresed in 2% agarose gel and then visualized under UV and interpreted. Results: GBV-C RNA was detected in seven samples from HIV patients (15.9%, 7/44). All patients with GBV-C coinfection were women. Conclusions: The frequency of GBV-C RNA coinfection among HIV patients in Dr. Moewardi General Hospital in Surakarta is 15.9% (7/44). Keywords: GBV-C, HIV, Surakarta

Abstract

Background: HIV / AIDS (Acquired Immune Deficiency Syndrome) is still a health problem in the world including in Indonesia. Approximately 36.7 people are infected with HIV in the world and in Indonesia until March 2017 recorded 242,699 cases. The recorded amount does not reflect the real number in the community because HIV infection often does not show specific symptoms before entering the stage of AIDS. This study aimed to examine the application of the health belief model on adherence to antiretroviral therapy among HIV/ AIDS patients in Surakarta, Central Java.Subject and  Method: This was a cross sectional study conducted at Dr. Moewardi Hospital, Surakarta, Central Java, on February 2018. A total sample of 284 HIV/AIDS patients was selected for this study by exhaustive sampling. The dependent variable was ARV Adherence. The independent variables were perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy. The data were collected using a questionnaire and analyzed by a path analysis.Results: Adherence directly increased with self-efficacy (b= 2.10; 95% CI = 0.85 to 3.34; p= 0.001), perceived benefit (b= 2.08; 95% CI= 1.15 to 3.00; p <0.001), and cue to action (b= 3.61; 95% CI= 0.86  to 6.36; p= 0.010) but decreased with higher perceived barrier (b= 2.08; 95% CI= 1.15 to 3.00; p<0.001). Adherence indirectly decreased with higher perceived severity and perceived susceptibility.Conclusion: Self-efficacy, perceived benefit, perceived barrier,  and cue to action directly affect the adherence to antiretroviral therapy. Perceived severity and perceived susceptibility indirectly affect the adherence to antiretroviral therapy. Keywords: ARV adherence, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, self-efficacyCorrespondence: Dyah Ayu Agustin.

Abstract

Candida albicans β-D-glucans examination has been used for invasive fungal detection in human blood and was approved by the Food and Drug Administration. However, the method is rarely used in Indonesia and also because the cost is hardly affordable. A modification of the method using enzymatic reaction is hoped will provide a simple and affordable measurement in human blood serum. β-D-glucans as heterogeneous molecules constitute the major carbohydrates fractions of cell wall and readily detected in supernatants of Candida albicans cultures are hydrolyzed by β glucanase to form D-glucose. This additional glucose is measured using Megazyme GOPOD-Format Procedure® at 510 nm. Candida albicans were identified and cultured was derived from a patient of Dr. Moewardi General Hospital, Surakarta in July, 2012. The results show that β-D-glucans from Candida albicans is measureable to the amount of μg/100 μL serum using this modification principle
