"Keberagaman spesies jamur yang dapat menyebabkan infeksi, serta resistensinya terhadap pengobatan antijamur, bervariasi tergantung terhadap wilayah dan factor lainnya. Penelitian ini bertujuan untuk mengetahui sebaran spesies dan kerentanan antijamur isolat jamur di Jakarta, Indonesia, untuk membantu membuat diagnosa dan tatalaksana yang personal terhadap pasien. Metode: Penelitian analitik retrospektif ini memanfaatkan data yang dikumpulkan selama periode tertentu. Spesimen jaringan pasien di Jakarta, Indonesia, diperiksa melalui mikroskop langsung dengan metode KOH dan kultur. Uji kerentanan dilakukan terhadap berbagai obat antijamur. Analisis data dilakukan dengan menggunakan SPSS. Hasil: Rata-rata usia pasien yang diduga (n= 289) dan terindikasi (n= 130) menderita infeksi jamur adalah masing-masing 39,23 dan 41,09 tahun. Lebih dari setengah jamur tidak terdeteksi pada pemeriksaan KOH, juga tidak tumbuh pada kultur (55%, n=159/289). Sebagian besar spesimen jaringan berasal dari sistem pernapasan (48.8%, n=141), khususnya sinus (21.1%, n= 61). Dari spesies jamur yang terisolasi, Candida muncul sebagai spesies yang paling menonjol (57/119), diikuti oleh Aspergillus (29/119) dan Mucorales (13/119). Pengujian kerentanan kami menunjukkan bahwa Candida menunjukkan pola kerentanan yang sebagian besar konsisten dengan penelitian yang dilakukan di Semarang dan Jakarta (72-100% sensitive); namun, jika dibandingkan dengan data dari berbagai negara lain, pola kerentanannya berbeda. Sebagian besar isolat Aspergillus sensitive (81-100%) terhadap antijamur umum. Namun demikian, profil kerentanannya bergantung pada variabilitas lokal. Kesimpulan: Penelitian ini memberikan data terkini mengenai distribusi spesies dan kerentanan antijamur dari isolat jamur di Jakarta, Indonesia. Studi ini beharap bisa membantu diagnosis dan strategi pengobatan yang ter-personalisasi terhadap masing- masing pasien infeksi jamur.

Background: The diversity of fungal species that can cause infections, along with their resistance to antifungal treatments varies depending on region and other factors. This study aims to investigate species distribution and susceptibility profile of fungals in Jakarta, Indonesia, to provide epidemiological data to develop tailored diagnosis and treatment. Methods: This retrospective analytic study utilized data collected over the specified period. Tissue specimens from patients in Jakarta, Indonesia, were examined through direct microscopy with KOH and culture methods. Susceptibility testing was performed for various antifungal drugs. Data analysis was conducted using SPSS. Results: The average age of patients suspected (n= 289) and indicated (n= 130) to have fungal infections was approximately 39.23 and 40.67 years, respectively. Most fungi that are not detected in direct examination with KOH, does not grow in culture (55%, n=159/289). Most tissue specimens came from the respiratory system (48.8%, n=141) particularly sinus (21.1%, n= 61). Out of the isolated fungal species, Candida emerged as the most prominent (57/119), followed by Aspergillus (29/119) and Mucorales (13/119). Our susceptibility testing revealed that Candida demonstrated susceptibility patterns that were largely consistent with studies conducted in Semarang and Jakarta (72-100% sensitive); however, when compared to regions outside of Indonesia, results differ. Most of Aspergillus isolates were sensitive (81-100%) to common antifungals. Nevertheless, its susceptibility profiles are subject to local variability. Conclusions: This study provides an updated data on the species distribution and antifungal susceptibility of fungal isolates in Jakarta, Indonesia. This study hopes to improve diagnosis and treatment strategies of fungal infections."

"This book provides a series of reports from the 1st International Conference on Model Hosts. This first of its kind meeting focused on invertebrate, vertebrate and amoeboid systems used for the study of host-pathogen interactions, virulence and immunity, as well as on the relevance of these pathogenesis systems and mammalian models. Importantly, a common, fundamental set of molecular mechanisms is employed by a significant number of microbial pathogens against a widely divergent array of metazoan hosts. Moreover, the evolutionarily conserved immune responses of these model hosts have contributed important insights to our understanding of the innate immune response of mammals."

"Kanker paru sebagai salah satu kanker terbanyak di dunia merupakan faktor risiko dari infeksi oportunistik, seperti mikosis paru. Mikosis paru masih jarang dikenali akibat diagnosis yang masih menjadi tantangan karena gejala dan radiologis yang tidak spesifik dan uji diagnosis yang tidak invasif masih belum diketahui kepastian tingkat akurasinya. Studi ini dilakukan untuk mengetahui nilai akurasi hasil pemeriksaan immunodiffusion test (IDT) yang menggunakan crude antigen dibandingkan dengan profil immunoglobulin G (IgG) spesifik Aspergillus sebagai baku emas yang menggunakan kit Dynamiker dengan hasil positif jika absorbansi di atas 120 AU/mL. Penelitian dilakukan melalui uji laboratorium dengan desain studi potong lintang. Prevalensi aspergillosis berdasarkan IgG spesifik Aspergillus didapatkan 25,7% dan nilai akurasi IDT didapatkan sensitivitas 44,4% (IK95% 21,5%-67,4%), spesifisitas 57,7% (IK95% 44,3%-71,1%), nilai duga positif 26,7% (IK95% 10,8%-42,5%), dan nilai duga negatif 75,0% (IK95% 61,6%-88,4%) dengan nilai Kappa sebesar 0.017. Selain itu, terdapat perbedaan yang bermakna secara statistik antara jenis kelamin dan indeks Brinkmann terhadap hasil pemeriksaan IDT Aspergillus (p<0,05). Oleh karena itu, IDT bukan merupakan metode diagnosis yang baik dan perlu adanya perbaikan terhadap antigen yang digunakan.

Lung cancer as one of the most common cancers in the world is a risk factor for opportunistic infections, such as pulmonary mycoses. Pulmonary mycoses is still rarely recognized due to the challenging diagnosis because the symptoms and radiology are not specific and the accuracy value of diagnostic tests that are not invasive is still not yet known. This study was conducted to determine the accuracy of immunodiffusion test (IDT) using crude antigen compared to the Aspergillus-specific immunoglobulin G (IgG) as the gold standard using Dynamiker kit with the positive result if the absorbance value is above 120 AU/mL. The method of this research is laboratory test with a cross-sectional study design. The prevalence of aspergillosis based on Aspergillus-specific IgG is 25.7% and the accuracy values of IDT are sensitivity 44.4% (95% CI 21.5%-67.4%), specificity 57.7% (95% CI 44.3%-71.1%), positive predictive value 26.7% (95% CI 10.8%-42.5%), and negative predictive value 75.0% (95% CI 61.6%-88.4%) with Kappa value 0.017. Besides, there was a statistically significant difference between gender and the Brinkmann Index on the results of IDT examination (p>0.05). Therefore, IDT is not a good or reliable diagnostic method and there is a need for improvement or correction of the antigen used."
