Although WNV infection in human has been reported for decades in several parts of the world, but it was diagnosed recently in 2014 in Indonesia. Approximately 80% of WNV infections in humans do not develop any symptoms. Elderly or those with immunosuppression, such as HIV/AIDS, are at greater risk for serious illness. Phylogenetic analysis has divided WNV into mainly Lineage 1(L1) and Lineage 2 (L2), which is geographically specifi c. Aims: To determine and phylogenetic analyse of WNV on HIV/AIDS Patients. Methods: The subjects were HIV/AIDS patients in Airlangga University Hospital. Examination of blood samples were performed in Institute of Tropical Disease Airlangga University. This study has been approved by Ethical Committee. A total of 30 HIV/ AIDS patients were enroled after obtainined informed consent, and examined for WNV RNA using RT-PCR in the envelope region (408 bps). Results: The results showed that 8 (25.81%) of 30 HIV/AIDS patients were WNV positive. The phylogenetic of one WNV strain in this study showed that it belongs to the L2. Only recently were those strains of L2 identifi ed outside of Africa. Conclusions: We found WNV as one of the potential coinfections in HIV/AIDS patients in Indonesia, and therefore it may in other countries too. Phylogenetic analysis of one strain revealed that the virus clustered in the lineage 2.

Background: Due to the high endemicity of hepatitis B in Lombok population, it is important to determine its prevalence among migrant workers (MWs), since Lombok contributes the most from Indonesia abroad. Hepatitis B virus (HBV) (sub)genotypes have geographic specifi c distribution. We have reported HBV strains from Indonesian MWs based on part of envelope region and several strains could not clearly be determined their subgenotypes. In this study we analyse the whole genome sequences of those strains. Methods: Sera were collected from Indonesian MWs, to be screened for HBsAg by Enzyme Immunoassay. Those with HBsAg positive were continued with HBV DNA detection and (sub)genotype/subtype determination based on envelope region and, for several strains, on whole genome sequences. Results: Seventeen point two percent (15/87) sera from the MWs who will go to their destination countries and 12.2% (15/124) of those come back to Indonesia were HBsAg positive. All of 30 HBsAg positive samples showed hepatitis B viremia by part of envelope gene amplifi cation. Six of HBV-B genotype and one HBV-C strains were whole genome sequenced. All together showed that the most isolates (96.2%, 25/26) belonged to HBV B3/adw2 and 3.8% was HBV C8/adrq+. The whole genome phylogenetic analysis of our strains supports a recent argument that subgenotypes B5, B7, B8, B9 could be considered as a quasi-subgenotype of B3, which is most commonly found in West Indonesia, including in Lombok. Conclusions: High prevalent of HBsAg carriers in the Indonesian MWs from Lombok were found, with the predominant of HBV B3/adw2. A tight screening of HBV to the MWs should be applied, in order to limit its transmission abroad. This study also confi rmed a recent fi nding that HBV-B subgenotypes need to be reclassifi ed.

Background: Dengue infection is distributed throughout the tropical areas around the world, including Indonesia. Dengue fever/ dengue hemorrhagic fever is a mosquito- borne disease caused by dengue virus of any serotype 1 (DEN1) to DEN4. Until now, therapy is based on pathophysiology. Aims: To evaluate the effi cacy and safety of MAC for the treatment of dengue infection. Methods: This clinical trial phase III was designed to study the inhibitory property of MAC against dengue virus (DENV) activity. A double-blind, randomized, controlled trial method was approved by Ethical Committee of Dr. Soetomo Hospital. This study was conducted from January 2012 to November 2013. After a signed informed consent, 530 patients, fever on day-1 or day-2, suspected dengue infection according to WHO criteria, showed positive result either by NS-1, and or IgM - IgG, were recruited. The subjects were divided into 2 groups. Group I received WHO standard treatment and 300 mg - MAC twice daily orally for 7 days. Group II received WHO standard treatment only. History, physical examination and complete blood count were done every day. Laboratory test (liver function, kidney function, CD4, CD8, VCAM, viral load) were performed on the fi rst, fourth and seventh day. Results: The results showed that the quantity of virus signifi cantly decreased in the treatment group (96.67%) compared to the control group (44.79%). Also showed that MAC did improve the immune system by increasing the value of CD8 (6.89%) and CD4 (9.95%). MAC provision does not interfere with the function of liver and kidney, and was well tolerated by the patients. Conclusions: MAC has signifi cant reduction of viral load level, may have immunomodulatory effects, prevent the plasma leakage, no hepatotoxic and nephrotoxic effects. MAC effi cacy as an antiviral agent against DENV infection has been very effectively illustrated.

Poster Session : PS 0421 ; Infectious Disease ; Demographic and Seroepidemiologic Patterns of Dengue Infection in Surabaya, Indonesia

Background: Dengue infection cases in Surabaya, contributed to more than 25% of cases in the East Java province during 2012-2013. This study was held to determine the patterns of dengue infection in Surabaya based on patient demographic and types of the virus prior to a clinical trial study of herbal medicine for the treatment of dengue infection Methods: A total of 460 patients with dengue infection diagnosed by specific non-structural 1 (NS1) antigen and or IgM/IgG examination, with fi rst or second day of fever, distributed in 10 hospitals and 15 health centers, obtained during January 2012 to November 2013, were included in this cross-sectional study. Strain identifi cation was based on multiplex RT-PCR for DEN1 to DEN4. The level of CD4 molecules on T-Lymphocytes were also quantitatively determined by ELISA Results: Around one third of the patients (34.6%) were aged between 21-60 y.o, with the rests were under 21 y.o. The dengue type was identifi ed in 209 patients. Among them, 77% were single type infection and 19% were double or more type infection, with DEN1 (34,9%) to be the most prevalent. The average level of CD4 molecules among patients was moderate (5.86±9,1 ng/mL), with no signifi cant difference level among each age group. During the two-year of study, the number of incidence per month fi uctuated between 1 to 80 cases, but tended not to follow general seasonal pattern. Conclusions: In Surabaya, Dengue infections are likely to be found widely among adults, with the pattern of incidence per month tend not to follow regular seasonal pattern. Among all strains, DEN 1 was most widely identifi ed, either as single or double infection with other strains during the period of study. Healthcare preparedness to care dengue infection patients should be conducted throughout the year.
