Cryptosporidium sp is a protozoan parasite, causes severe diarrhea in imrnunodeticient hosts like the HIV/AIDS patients. Diagnosis of cryptosporidiosis by finding the oocyst from stool by modified acid fast staining, is insensitive. Coproantigen detection offers more sensitive and specific technique to detect Cqptosporidium infection. The objective of this study is to determine eryptosporidiosis proportion among HTV/AIDS patients by Cryptosporidial antigen detection in stool compare it to modified acid fast staining and determine its correlation with ooeyts count. A number of 95 stool specimens from the HIV/AIDS patients with chronic diarrhea were subjected to coproantigen ELISA test and modified acid-fast staining (gold standard). The frequency of Criptosporidial infection was 36,8% and 11,6% respectively by coproantigen detection and AF staining with 100% sensitivity and 71,4% specificity. There is no correlation between optical density and oocyst count."

"Human Immunodeficiency Virus type-I (HIV-1) merupakan penyebab sindroma penurunan sistem imun tubuh yang disebut dengan Acquired Immunodeficiency Syndrome (AIDS). Infeksi HIV-I di dunia dan Indonesia cenderung meningkat. Pemeriksaan yang cepat dan spesifik diperlukan untuk mencegah penyebaran infeksi HIV-I. Berbagai teknik telah dikembangkan untuk deteksi infeksi HIV-I. Pada penelitian ini dikembangkan pemeriksaan RT-PCR HIV-1 Mikrobiologi FKUI (in-house RT-PCR) untuk mendapatkan uji alternatif deteksi HIV-1. Sebanyak 46 plasma dan serum kelompok berperilaku risiko tinggi yang berkunjung ke klinik VCT . RSUP Sanglah Denpasar, telah diperiksa dalam penelitian ini. Serum diperiksa dengan 3 kit rapid test yang berbeda yaitu DetermineTM HIV-1/2 (Abbott), ImmunoCombR HIV 1 & 2 BiSpot (Organics), dan SerodieR HIV-1/2 (Fujirebio Inc.). Plasma diuji dengan pemeriksaan RTPCR generasi I menggunakan primer spesifik terhadap daerah gag dan RT-PCR generasi 2 menggunakan primer spesifik terhadap daerah protease dari genom HIV-1. Hasil rapid test menunjukkan dari 46 sampel, sebanyak 26 serum (56,5%) reaktif dan 20 serum (43,5%) non-reaktif. Tingkat sensitivitas, spesifisitas, nilai duga positif, dan nilai duga negatif RT-PCR generasi 1 secara berturut-turut adalah 80,8%, 95%, 95,5%, dan 79,2%, sedangkan rasio kemungkinan positif dan negatif adalah 16,2, dan 0,2. Pemeriksaan RTPCR generasi 2 menunjukkan tingkat sensitivitas 65,4%, spesifisitas 90%, nilai duga positif 89,5%, nilai duga negatif 66,7%, rasio kemungkinan positif 6,5, dan rasio kemungkinan negatif 0,4. Teknik RT-PCR yang menggunakan primer tersebut dapat mendeteksi HIV pada semua stadium klinis WHO pada kelompok ini. Sensitivitas dan spesifisitas RT-PCR generasi 1 lebih baik daripada RT-PCR generasi 2, tetapi, masih lebih rendah daripada baku emas, Secara keseluruhan, RT-PCR pada penelitian ini belum dapat direkomendasikan sebagai uji altematif baik uji skrining maupun uji konfirmasi dalam mendeteksi infeksi HIV-1.

Human Immunodeficiency Virus type 1 (HIV-1) can cause decrease of immune response which is called Acquired Immunodeficiency Syndrome (AIDS). HIV-l infection in the world and Indonesia tends to increase. Many techniques were developed to detect HIV-1 infection. A specific and rapid diagnosis is needed to prevent transmission of HIV-1 infection. In this study, we performed RT-PCR HIV-1 Microbiology FKUI (in-house RT-PCR) as an alternative test to detect HIV-1. Forty six plasmas and serums from high risk behavior group who visited VCT Clinic Sanglah General Hospital, Denpasar were used in this study. Serums were tested with 3 different rapid test kits i.e. Determine ° IIIV-112 (Abbott), immunoComb HIV I & 2 BiSpot (Orgenics), and Serodia ' HIV-112 (Fujirebio Inc.). Plasmas were tested with I generation RT-PCR which used specific primers to gag region in HIV-1 genome and specific primers to protease region in IIIV-1 genome for 2nd generation RT-PCR. Results of rapid test demonstrated 26 serums (56.5%) were reactive and 20 serums (43.5%) were non-reactive. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 1st generation RT-PCR was 80.8%, 95%, 95.5%, 79.2%, whereas positive likelihood ratio (LR +) and negative likelihood ratio (LR -) was 16.2, and 0.2, respectively. The 2"d generation RT-PCR showed sensitivity, specificity, PPV, NPV, LR (+), and LR (-) was 65.4%, 90%, 89.5%, 66.7%, 6.5, and 0.4, respectively. These in-house RT-PCR could detect HIV-1 in all WHO clinical staging in this group. This study showed that lsi generation RT-PCR gives better results than 2"d generation RT-PCR. But still inferior than rapid test to detect HIV-1 infection. Overall, RT-PCR in this study has not been recommended yet as an alternative test to detect HIV-I infection."

"In this book, expert HIV researchers critically review every aspect of this highly evolving and topical subject. The opening chapters deal with the epidemiology, global magnitude and biologic mechanisms of HIV-1 transmission from mother to child through breastfeeding and include considerations of the virus (quantity, compartments, characteristics) and the host (genetic, immunity-innate, cellular, humoral). The effects of breastfeeding on the HIV-infected mother’s health and nutritional status, and the social and cultural issues associated with the practice of breastfeeding are also discussed. The next few chapters provide cutting-edge reviews of the latest approaches to prevention of HIV transmission to the infant through breastfeeding, including antiretroviral strategies, nutritional and immune-based approaches, and treatment of expressed breast milk. The remaining chapters provide a fascinating review of the many iterations this subject has received, as reflected in the several different sets of guidelines for infant feeding by HIV-infected mothers issued by the World Health Organization, and a debate by leading scientists on whether HIV-infected mothers should breastfeed their infants-in resource-limited and in resource-rich settings. A comprehensive overview of the current state of implementing the new evidence for prevention of breastfeeding transmission of HIV all over the world is also presented."

"Serologic assays are commonly used for screening (ELISA) and for confirmation (Western blot) of HIV-1 infection; however, both assays have potentially yielded the false-positive or false-negative results. In this study, a diagnostic RTPCR assay as an alternative test for detection of HIV-1 was developed. Forty-six plasma specimens from highly risky groups, who visited a voluntary counseling and testing for HIV (VCT) in Sanglah Clinic of General Hospital, Denpasar, Bali, were tested by RT-PCR assay with specific primers for Pol region of HIV-1 genome. The results of the RT-PCR tests were then compared with those of serologic tests to obtain the sensitivity and specificity of RT-PCR assay.The results of this study showed that the RT-PCR assay could detect 17 (sensitivity: 65.4%) of 26 serologically positive specimens and was unexpectedly able to detect 2 (specificity: 90%) of 20 serologically negative specimens. Thus, the RT-PCR assay developed in this study is potential to be used as an alternative test, even though there are numerous aspects, particularly the sensitivity, that need to be improved in further research."

"Perubahan tunika intima media (TIM) karotis dan flow mediated dilatation (FMD) dapat digunakan sebagai pemeriksaan untuk mengetahui aterosklerosis dini. Pada ODHA TIM karotis dan FMD dapat dipengaruhi oleh inflamasi kronik akibat infeksi HIV itu sendiri, efek samping terapi ARV, dan koinfeksi virus atau bakteri lain. Oleh karena itu, penelitian ini menelaah kinetika penanda inflamasi (CRP, ICAM-1 dan sTNFR), kondroitin sulfat (KS) serta antibodi CMV, mengorelasikannya dengan perubahan TIM karotis dan FMD pada ODHA yang memulai terapi ARV serta dibandingkan dengan kontrol sehat setelah 60 bulan terapi ARV.Desain penelitian kohort prospektif dan cross-sectional. Subjek penelitian didapatkan dengan consecutive sampling dari Januari 2013 sampai Desember 2014, diamati dalam 3 kurun waktu selama 60 bulan di RSUPN Dr. Cipto Mangunkusumo. Dilakukan pemeriksaan USG pembuluh darah karotis pada semua subjek, diamati perubahan ketebalan TIM karotis, FMD, kadar CD4, indeks massa tubuh, kadar CRP, ICAM-1, sTNFR, KS, dan antibodi CMV setiap periode pengamatan. Data dianalisis menggunakan uji Mann Whitney U, Wilcoxon, Spearman’s correlation, Pearson’s correlation dan multiple linear regression.Tidak didapatkan perubahan TIM karotis setelah dilakukan terapi ARV selama 12 bulan dan 60 bulan. Tidak ada perbedaan bermakna untuk TIM karotis dan FMD antara ODHA dengan kontrol sehat. ICAM-1 memiliki korelasi dengan TIM karotis pada kunjungan awal sebelum terapi dan KS memiliki korelasi dengan TIM karotis setelah 60 bulan terapi ARV. FMD memiliki korelasi negatif dengan KS dan antibodi CMV lysate pada ODHA, sedangkan pada kontrol sehat FMD memiliki korelasi negatif dengan sTNFR dan KS, namun memiliki korelasi kuat dengan antibodi CMV gB.Inflamasi kronik pada ODHA tidak menyebabkan perubahan TIM karoti. KS dan antibodi CMV lysate dapat memengaruhi nilai FMD pada ODHA. Pada kontrol sehat, KS dan sTNFR bisa memengaruhi nilai FMD, namun antibodi CMV gB bisa berfungsi sebagai faktor pelindung.

Carotid intima-media thickness (CIMT) and flow mediated dilatation (FMD) used to detect early atherosclerosis. In people living with hiv/aids (PLWH), CIMT and FMD could be influenced by chronic inflammation affected HIV infection, ART and co-infection. We did the research to study the kinetic of inflammation biomarkers (CRP, ICAM-1 and sTNFR), chondroitine sulfate (CS) and CMV reactive antibodies, to find correlation for CIMT and FMD starting ART and compare to healthy control (HC) after 60 months.

This was a cohort prospective study and repeated cross sectional. The subjects were collected from January 2013 until December 2014, follow up to 60 months. Every visit we did USG for carotid artery and FMD at brachial artery, CD4, BMI, CRP, ICAM-1, sTNFR, CS and CMV antibodies level were also measured. Data were analyzed using Mann Whitney U, Wilcoxon, Spearman’s correlation, Pearson’s correlation and multiple linear regression.

There were no differences in CIMT changes in 60 years follow up. There were no differences of CIMT and FMD between PLWH and HC. ICAM-1 had a correlation with CIMT before starting ARV therapy and CS had a correlation with CIMT after 60 months of ARV therapy. FMD had a negative correlation with CS and CMV Lysate antibody for PLWH. FMD had negative correlation to CS and sTNFR but strong correlation to CMV gB antibody in HC.

Chronic inflammation in PLWH did not cause CIMT changes. CS and CMV Lysate antibody may influenced FMD in PLWH, but for HC, CS and sTNFR may influenced FMD, but CMV gB antibody could be a protective factor.

"Dalam upaya menginduksi kekebalan berspektrum luas yang responsif terhadap subtipe-subtipe HIV-1 yang berbeda, telah diteliti imunisasi vaksin DNA menggunakan vektor plasmid DNA dan virus fowlpox rekombinan dengan memanfaatkan gen-gen HIV-1 yang dirancang dari runutan konsensus turunan subtipe-subtipe HIV-1 di dunia yang mengekspresikan semua protein dari genom HIV-1 dengan peptida berukuran 30 asam amino yang overlapping dan tersusun secara acak (scrambled antigen vaccines, atau SAVINE).Tiga grup hewan coba yang terdiri dari masing-masing tujuh beruk (Macaca nemestrina) diimunisasi dengan regimen vaksin DNA standar dengan veklor plasmid DNA pHIS-64 dan vektor virus fowlpox rekombinan (rFPV) berbasis gen gag dan pol dan HIV-1 subtipe B, regimen vaksin DNA SAVINE dengan vektor pHIS-64 dan vektor rFPV berbasis genom HIV-1 yang diacak, serta vektor plasmid pHIS-64 dan FPV yang tidak mengandung gen sebagai grup kontrol. Respon kebal selular diamati dengan teknik ELiSpot dan pewamaan silokin intraselular, sedangkan respon kebal humoral diamati dengan teknik ELISA. Pada ketujuh hewan coba yang diimunisasi dengan vaksin DNA HIV-1 standar, secara umum hasil penelitian menunjukkan terinduksinya respon kebal selular terhadap protein Gag HIV-1 serta respon kebal humoral yang ditunjukkan dengan terdeteksinya antibodi terhadap protein p24 HIV-1. Respon kebal selular silang terhadap protein Gag HIV-1 dari subtipe yang berbeda juga ditunjukkan pada grup yang sama. Namun upaya melakukan imunisasi boosting ke-dua dengan vektor rFPV tidak menunjukkan perbaikan induksi respon kebal. Berbeda dari grup hewan coba yang menerima regimen vaksin DNA HIV-1 standar, pada grup yang menerima regimen vaksin DNA HIV-1 SAVINE secara umum tidak menunjukkan adanya induksi respon kebal, kecuali pada satu ekor hewan yang menunjukkan respon kebal selular yang lebih luas terhadap protein Pol dan protein-protein lain HIV-1 meski pada tingkat induksi yang amat rendah. Pengembangan teknologi vaksin SAVINE terus diperbaiki dan disempumakan dengan kemungkinan melibatkan vektor virus aktif yang lain sehingga induksi respon kebal yang diharapkan bisa tercapai.Specific Immune Responses to the Human Immunodeficiency Virus Type-1 (HIV-1) Proteins In Pigtail Macaque (Macaca nemestrina) Immunized with Whole Gene and Whole Virus Scrambled Antigen Vaccines

T cell immunity plays a critical role in controlling HIV-1 viremia, and encoding a limited set of HIV-1 genes within DNA and poxvirus vectors can, when used sequentially, induce high levels of T cell immunity in primates. However, a limited breadth of T cell immunity exposes the host to potential infection with either genetically diverse HIV-1 strains or T cell escape variants of HIV-1. In an attempt to induce maximally broad immunity, we examined DNA (prime) and recombinant Fowlpox virus (rFPV, boost) vaccines encoding all HIV-1 genes derived from a global HIV-1 consensus sequence, but expressed as multiple overlapping scrambled 30 amino acid segments (scrambled antigen vaccines, or SAVINEs).

Three groups of 7 pigtail macaques (Macaca nemestrina) were immunized with sets of DNA and rFPV expressing Gag/Pol antigens only, the whole genome SAVINE antigens, or no HIV-1 antigens. T cell immunity was monitored by ELISpot and intracellular cytokine staining, while the humoral immune response was monitored by p24 antibody capture ELISA. High levels of cross-subtype HIV-specific T cell immunity to Gag were consistently induced in the 7 macaques primed with DNA and rFPV vaccines expressing Gag/Poi as intact proteins. The humoral immunity was also induced in the animals from the same group. It was however, difficult to repeatedly boost immunity with further rFPV immunizations, presumably reflecting high levels of anti-FPV immunity. Unfortunately, this vaccine study did not consistently achieve a broadened level of T cell immunity to multiple HIV genes utilizing the novel whole-virus SAVINE approach, with only one of 7 immunized animals generating broad T cell immunity to multiple HIV-1 proteins. Further refinements are planned with alternate vector strategies to evaluate the potential of the SAVINE technology."
