Uveitis adalah inflamasi intraokular yang terjadi pada saluran uvea mata ataupun jaringan yang berada di dekatnya, diantaranya retina atau vitreous. Uveitis merupakan penyebab kebutaan nomor tiga di dunia dengan prevalensi tertinggi pada kelompok umur pekerja aktif 20-50 tahun . Selama ini diagnosis uveitis infeksi dan non-infeksi di Indonesia ditegakkan secara klinis dan didukung pemeriksaan serologi darah. Pemeriksaan antibodi pada cairan akuos dan serum serta marka genetik, khususnya HLA B-27 belum pernah dilakukan. Penelitian ini dilakukan untuk memberikan alternatif pendukung diagnosis klinis yaitu pemeriksaan deteksi molekuler HLA B-27 dan deteksi antibodi dengan perhitungan koefisien Goldmann-Witmer. Subjek penelitian adalah pasien uveitis aktif di Poliklinik Infeksi dan Imunologi RSCM Kirana yang berjumlah 79 orang. Berdasarkan koefisien Goldmann-Witmer, mikroba penyebab uveitis adalah Toxoplasma gondii dan virus Varicella zoster. Gen HLA-B27 ditemukan pada enam subjek penelitian dan terdapat kesesuaian dengan kasus uveitis non-infeksi tetapi belum dapat dibuktikan kemaknaannya secara statistik.

Uveitis is an intraocular inflammation which occurs on the uvea or its surrounding tissue such as retina or vitreous. Uveitis is known as the third major cause of blindness in the world with the highest prevalence is productive age group 20 50 years old . To date, infectious and non infectious uveitis stipulation in Indonesia is based on clinical examination and serology test. The aqueous and serum antibody titer measurement as well as genetic marker examination, especially on HLA B27, has never been done before. In this research we perform HLA B27 detection through molecular analysis and antibody titer measurement to know the Goldmann Whitmer coefficient. Sample size used in this research is 79 patients with active uveitis obtained from ldquo Poliklinik Infeksi dan Imunologi RSCM Kirana rdquo . The analysis of Goldmann Whitmer coefficient showed that the pathogens responsible for uveitis are Toxoplasma gondii and Varicella zoster. HLA B27 were found in six patients and there is similiarity between non infectious uveitis but this value does not have prove statistically.

Latar belakang : Cytomegalovirus (CMV) merupakan salah satu infeksi oportunistik pada pasien dengan sindrom immunodefisiensi (AIDS). Gejala klinis dan CT scan tidak dapat menegakkan diagnosa definitif ensefalitis CMV. Oleh karena itu diperlukan uji alternatif untuk menegakkan diagnosis infeksi CMV pada pasien HIV dengan infeksi otak. Salah satu uji yang sensitif dan spesifik adalah Real Time Polymerase Chain Reaction (rPCR). Tujuan : Mendapatkan uji deteksi molekular CMV pada pasien HIV dengan tersangka infeksi otak. Metode : Penelitian dilakukan dalam 3 tahap. Tahap 1 adalah optimasi konsentrasi primer, probe, suhu annealing, volume elusi ekstraksi DNA, dan volume cetakan. Tahap 2 adalah uji spesifisitas (reaksi silang) dan uji sensitivitas (ambang batas deteksi DNA) rPCR dan tahap 3 adalah penerapan uji rPCR yang sudah dioptimasi terhadap sampel plasma, urin, dan LCS. Hasil : Kondisi optimal uji rPCR telah diperoleh dengan konsentrasi primer dan probe 0,1 μM, dengan kondisi suhu reaksi rPCR: aktivasi enzim pada 950C selama 3 menit; 45 siklus pada 950C selama 15 detik (denaturasi) dan 560C selama 1 menit (annealing dan ekstensi). Volume elusi ekstraksi DNA yang optimal untuk ketiga jenis sampel (LCS, plasma dan urin) adalah 40 μL, dan volume cetakan rPCR untuk LCS, plasma, dan urin, masing-masing adalah 5, 4, dan 3 μL. Uji rPCR mampu mendeteksi DNA pada 50.000 jumlah kopi/mL dan tidak bereaksi silang dengan Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus saprophyticus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Mycobacterium tuberculosis, Candida spp, Toxoplasma gondii, EBV,HSV,dan VZV. Penerapan uji rPCR pada sampel klinis memberikan hasil negatif pada semua sampel LCS, 72,22% positif pada sampel plasma, dan 72,22% positif pada sampel urin. Kesimpulan: Telah dilakukan optimasi uji rPCR dengan minimal deteksi DNA CMV 50.000 jumlah kopi/mL dan tidak bereaksi silang dengan mikroorganisme yang berpotensi menyebabkan positif palsu (false positive).ABSTRACT
Background: Cytomegalovirus (CMV) is one of opportunistic infections in patients with Aquired Immunodeficiency Syndrome (AIDS). Clinical manifestations are not typical, and CT scans can not define encephalitis CMV specifically. Therefore, it is important to apply an alternative assay for sensitive and specific detection of CMV infection in HIV patients with suspected central nervous system (CNS) infections. One of the assays is real time polymerase chain reaction (rPCR). Objective: To obtain a molecular assay for detection of CMV in HIV patients with suspect CNS infections. Methods: This study was conducted in three phases. The first is optimization of concentrations of primers, probe, annealing temperature, final elution of DNA extraction, and volume of PCR template. The second is determinations of sensitivity (minimal detection of DNA) and specificity (cross-reaction) of the optimized rPCR, and the third is application of the rPCR for clinical samples of plasma, urine, and liquor cerebrospinal (LCS). Results: The rPCR reaction showed optimal concentrations of primers and probe at 0.1 μM, with thermal cycler: 950C for 3 min (enzyme activation), followed by 45 cycles of 950C for 15 sec (denaturation) and 560C for 1 min (annealing and extension). Final elution of DNA extraction was 40 μL and volume of PCR templates for urine, plasma, and LCS was 3, 4, and 5 μL, respectively. The rPCR had minimal detection of DNA at 50,000 copies/mL and was not cross-reacted with Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus saprophyticus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Mycobacterium tuberculosis, Candida spp, Toxoplasma gondii, Epstein-Bar Virus (EBV), Herpes Simplex Virus (HSV) and Varicella Zoster Virus (VZV). Application of rPCR for clinical samples showed that the rPCR yielded 72.22% positive for plasma or urine, and negative for all LCS samples. Conclusion: The rPCR has been optimized in this study with minimal DNA detection at 50,000 copies/mL and was not cross-reacted with other microorganisms that are potential to cause false positive results.;Background: Cytomegalovirus (CMV) is one of opportunistic infections in patients with Aquired Immunodeficiency Syndrome (AIDS).

Munculnya varian virus influenza yang berpotensi menimbulkan pandemi merupakan kejadian yang tidak terduga dan jarang terjadi. Penanganan dalam situasi seperti ini membutuhkan produksi vaksin skala besar dalam waktu singkat seperti pada kasus virus influenza H1N1 pdm09. Salah satu strategi yang dapat dilakukan adalah produksi vaksin subunit dengan memanfaatkan sistem ekspresi ragi untuk memproduksi protein antigen rekombinan. Tujuan penelitian ini adalah mengekspresi protein fusi HA1-MA2-NS1 rekombinan untuk pengembangan vaksin subunit. Plasmid pPICZαA-HA1-MA2-NS1 linear diintegrasikan ke dalam genom Pischia pastoris strain GS115 melalui rekombinasi homolog. Proses transformasi ini dilakukan dengan metode elektroporasi dan menghasilkan 13 klon ragi yang mengandung multiple integran gen fusi HA1-MA2-NS1. Analisis bioinformatika menduga protein fusi memiliki berat molekul 75-85 kDa. Visualisasi protein pada supernatan dan pelet dengan SDS-PAGE memperlihatkan adanya pita protein dengan ukuran yang diharapkan. Hasil western blot pada pellet mendeteksi ukuran protein target antara 42-135 kDa. Pemurnian protein fusi dengan NI-NTA gagal dilakukan dan diduga karena sedikitnya jumlah protein fusi yang terbentuk sehingga tidak terdeteksi pada visualisasi SDS-PAGE. ...... The emergence of influenza virus variants that could potentially cause a pandemic is an unforeseen occurrence and rare. Handling a situation like this requires a large-scale vaccine production in a short time as in the case of the H1N1 virus pdm09. One strategy that can be done is a subunit vaccine production by utilizing a yeast expression system to produce recombinant protein antigens. The purpose of this study was to express a recombinant proteins of fusion HA1- MA2-NS1 for subunit vaccine development. PPICZαA HA1-MA2-NS1 linear plasmid integrated into the genome Pichia pastoris strain GS115 through homologous recombination. This transformation process is carried out by electroporation method and generating 13 yeast clones containing multiple genes HA1-MA2-NS1 integrant. Bioinformatics analysis of protein suspect fusion protein has a molecular weight of 75-85 kDa. Visualization of proteins in the supernatant and pellet by SDS-PAGE showed protein bands with sizes expected. But western blot results in the pellet detect the target protein size between 42-135 kDa. Purification of fusion proteins with NI-NTA were failed due to small amount of fusion protein that undetected on SDS-PAGE visualization.

Penyakit tuberkulosis (TB) merupakan penyakit infeksi yang disebabkan oleh bakteri Mycobacterium tuberculosis. Infeksi TB telah menjadi masalah kesehatan utama di seluruh dunia. Peningkatan jumlah kasus TB disebabkan oleh munculnya TB yang resisten terhadap obat (MDR-TB/ Multi Drugs Resistant) dan koninfeksi dengan HIV. BCG merupakan vaksin yang tersedia saat ini, efisien melindungi manifestasi penyakit parah pada anak, tetapi vaksin ini tidak mencegah pembentukan TB laten atau reaktivasi penyakit paru pada orang dewasa. Protein rpfB M.tuberculosis merupakan faktor virulensi dan resusitasi dari dormansi M. tuberculosis. Protein ini diketahui berperan dalam pemecahan peptidoglikan dari dinding sel bakteri dan menstimulasi pertumbuhan bakteri dan resusitasi dari keadaan laten. Hal ini menjelaskan bahwa protein rpfB mempunyai sifat imunogenik yang tinggi dan berpotensi untuk dikenali oleh sistem imun dan dikembangkan strategi vaksin yang berbasis vaksin subunit yang dapat digunakan untuk menstimulasi sel T. Strain yang digunakan pada penelitian ini adalah strain Beijing yang diisolasi di Indonesia dan strain H37Rv sebagai kontrol. Strain Beijing diketahui bersifat lebih virulen, relatif resisten terhadap obat dan cenderung menyebabkan penyakit paru pada orang dewasa dibandingkan strain lain. Gen rpfB strain Beijing dan H37Rv diamplifikasi dengan teknik PCR dan diinsersikan ke dalam vector pGEX-6P-1. Plasmid rekombinan pGEX 6P-1-rpfB ditransformasi ke E.coli BL21 untuk diekspresikan. Protein rpfB diekspresikan dengan induksi IPTG. E.coli BL21 berhasil ditransformasi dengan plasmid rekombinan dengan arah orientasi yang benar. Analisis epitop sel T CD4+ dan CD8+ memperlihatkan tidak ada mutasi yang ditemukan pada asam amino yang menjadi epitop pengenalan sel T CD4+ dan CD8+. Protein rpfB rekombinan berhasil diekspresikan pada E.coli BL21. Hasil ekspresi protein rpfB menunjukkan pita protein yang berada pada ukuran 66 kDa. Analisis western blot mengkonfirmasi kebenaran protein rpfB dengan antibodi anti-GST. ......Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis pathogen. TB infection has been a major threat to global health. The wide spread of TB cases attributed by TB drug resistant (MDR-TB/ Multi Drugs Resistant) and HIV coinfection. BCG is a current available vaccine for TB, is efficient for protection manifestations of childhood disease, but it has failed to prevent latently TB form or reactivation adult pulmonary. rpfB protein need for virulent and resuscitation from dormant Mtb. rpfB protein is known to involved in peptidoglycan cleaveage from bacteria cell wall and stimulate bacteria growth and resuscitation of latently. It suggests that rpfB protein has highly immunogenic characteristic and potent to recognized immune respons and to be developed vaccine strategy based on subunit vaccine which can use to stimulate T cells. Strains that used in this research, consist of Beijing strain that isolated from Indonesia and H37Rv strain as control. Beijing strain is known more virulent, relatively resistant to drug and tend to caused adult pulmonary disease compared to other strain. rpfB gene of Beijing strain and H37Rv amplify by PCR and insert to pGEX-6P-1 vector. Recombinant plasmid (pGEX-6P-1-rpfB) is transformed to Escherichia coli BL21 for protein expression. rpfB protein expressed by IPTG induction. E.coli BL21 was successed to transformed with recombinant plasmid in correctly orientation. Epitope analysis of CD4+ T cell and CD8+ T cell shown no mutation found in amino acid that encoded recognized epitope of CD4+ T cell and CD8+ T cell. Recombinant protein has been expressed in E.coli BL21. The result of expression showed the molecular weight of protein band is in 66 kDa. Western blot analysis confirmed correct rpfB protein using anti-GST antibody.
