"Aspergilosis paru merupakan infeksi oportunistik yang disebabkan oleh jamur Aspergillus spp. Insidensi aspergilosis paru cenderung semakin meningkat seiring dengan peningkatan penggunaan obat-obatan imunosupresan seperti kortikosteroid dan terapi sitotoksik. Sulitnya penegakan diagnosis aspergilosis paru menjadi tantangan disebabkan tanda dan gejala klinis yang tidak spesifik serta biopsi jaringan sebagai baku emas yang bersifat invasif. Pemeriksaan kultur sputum dan deteksi antibodi merupakan pemeriksaan yang rutin dilakukan pada pasien suspek aspergilosis paru yang dikirim ke Laboratorium Mikologi Departemen Parasitologi FKUI, namun belum tersedia data mengenai nilai diagnostik deteksi antibodi dalam mendiagnosis aspergilosis paru. Tujuan penelitian ini adalah membandingkan pemeriksaan deteksi antibodi dengan crude antigen Aspergillus dengan metode imunodifusi dengan kultur sputum sebagai tes rujukan. Penelitian berdesain potong lintang dengan sampel berjumlah 689 rekam medis dari pasien suspek aspergilosis paru yang melakukan pemeriksaan kultur sputum dan deteksi antibodi di Laboratorium Mikologi Departemen Parasitologi FKUI tahun 2008-2015. Dari analisis deskriptif didapatkan prevalensi aspergilosis paru berdasarkan hasil positif kultur sebesar 0,4. Dari uji diagnostik deteksi antibodi dengan tabel 2x2, nilai sensitivitas 33,33 dan spesifisitas 95,62 serta terdapatnya perbedaan yang bermakna.

Pulmonary aspergillosis is an opportunistic infection caused by Aspergillus spp mold. The incidence of this infection has dramatically increased which is related to the increasing utilization of immunosuppressive drugs such as corticosteroids and cytotoxic therapy. Diagnosis of pulmonary aspergillosis has been challenging since not only the signs and symptoms of the disease are nonspecific, but also tissue biopsy as gold standard is considered invasive. Sputum culture and antibody detection has been routine examinations done to the patient with suspected pulmonary aspergillosis sent to the Mycology Laboratory of Department of Parasitology FMUI, but the diagnostic value of antibody detection is not available.

The aim of this study is to compare antibody detection with immunodiffusion method using crude antigen of Aspergillus with sputum culture as reference test. This cross sectional study used 689 samples obtained from medical records of patients with suspected pulmonary aspergillosis who undergo both sputum culture examination and antibody detection in Mycology Laboratory of Department of Parasitology FMUI in 2008 2015. Descriptive analysis showed the prevalence of pulmonary aspergillosis based on positive culture result is 0,4. The sensitivity and specificity of antibody detection are 33,33 and 95,62 respectively, resulted from diagnostic test using 2x2 table. Statistical analysis using McNemar rsquo. test shows significant difference between mentioned examinations and low level of agreement Kappa 0,026."

"Latar belakang: Diagnosis aspergilosis paru invasif (API) cukup sulit dilakukan karena karakteristik klinis dan hasil pencitraan yang tidak spesifik. Biopsi tidak bisa dilakukan karena risiko komplikasi Deteksi antigen galaktomanan (GM) digunakan untuk metode noninvasif karena sensitivitas dan spesifisitas yang tinggi, namun mahal dan jarang tersedia. Uji imunodifusi (IDT) bisa menjadi alternatif karena lebih murah dan mudah, namun perlu diketahui akurasi IDT pada pasien terduga API. Tujuan: Mengetahui nilai diagnostik IDT dibandingkan terhadap deteksi GM dalam mendiagnosis API. Metode: Pengumpulan serum dilakukan di Laboratorium Departemen Parasitologi FKUI sejak Oktober 2019—Oktober 2020 pada pasien terduga API yang berasal dari berbagai rumah sakit di Jakarta. Serum diperiksan menggunakan IDT dan deteksi GM. Metode IDT menggunakan antigen crude Aspergillus buatan Laboratorium Departemen Parasitologi FKUI, sedangkan deteksi GM menggunakan kit PlateliaTM (Bio-Rad, Prancis). Hasil: Sebanyak 92 sampel serum pasien diuji. Proporsi hasil deteksi GM dan IDT berturut-turut sebesar 31.5% dan 42.4%. Hasil menunjukkan bahwa sensitivitas dan spesifisitas IDT berturut-turut sebesar 33.33% dan 69.81%. Selain itu, rasio kemungkinan positif dan negatif berturut-turut sebesar 1.10 dan 0.95. Nilai duga positif dan negatif serta akurasi berturut-turut sebesar 44.83%, 58.73%, dan 54.35%. Tidak ada beda proporsi IDT terhadap deteksi GM (P>0.05) Simpulan: Nilai diagnostik IDT sama dibandingkan terhadap deteksi GM.

Background: The diagnosis of invasive pulmonary aspergillosis (API) is quite challenging because of non-specific clinical characteristics and imaging results. A biopsy cannot be performed because of the risk of complications. Galactomannan antigen (GM) detection is used as a noninvasive method because of its high sensitivity and specificity, but it is expensive and rarely available. Immunodiffusion test (IDT) can be an alternative method, because it is cheaper and easier, but it is necessary to know the accuracy of IDT in patients suspected of API.

Objective: Determine the diagnostic value of Aspergillus IDT compared to GM detection in diagnosing API.

Methods: Serum collection was carried out at the Parasitology Laboratory of FMUI from October 2019-October 2020 in patients suspected of API from various hospitals in Jakarta. The sera were examined using the Aspergillus IDT and GM detection. The IDT method uses crude Aspergillus antigen that was conducted at the Parasitology Laboratory of FMUI, while GM detection uses the PlateliaTM kit (Bio-Rad, France).

Results: A total of 92 patient serum samples were tested. The proportion of detection results for GM and IDT was 31.5% and 42.4%, respectively. The results showed that the sensitivity and specificity of IDT were 33.33% and 69.81%, respectively. Also, the positive and negative likelihood ratios are 1.10 and 0.95, respectively. Positive and negative predictive values and accuracy were 44.83%, 58.73%, and 54.35%, respectively. There was no difference in the proportion of IDT to GM detection (P> 0.05).

Conclusion: IDT diagnostic value is the same as compared to GM detection."

Background: The diagnosis tuberculosis (TB) especialy in HIV patients remains a major obstacle to global control of TB, especially in resource limited settings. Light microscopy in sputum smears as common method in detection acid-fast bacilli (AFB) is specific but it only detects 30% to 40% of TB patients, while culture methods as gold standart in TB diagnostic require several weeks of incubation time. Genotypic method (polymerase chain reaction (PCR) and isothermal amplification) is known very sensitive and works fast but it requires special equipment and complex protocols in amplifying and detection amplified products. Cross-priming amplification (CPA) principle is isothermal amplification using multiple cross-linked primers (six to eight primers) and detection of amplified products is performed on special design plastic which is easy to performed and identified.

Objective: The study aimed to determine difference of PCR and CPA to detect M. tuberculosis in sputum specimens from suspected pulmonary tuberculosis without/with HIV patients.

Methods: 20 sputum samples suspected pulmonary TB of non-HIV patients and 37 sputum samples suspected pulmonary TB of HIV patients were subjected to CPA and PCR TB LMK FKUI.

Results:. All samples which were positive by CPA were also PCR positive but 20% result that were CPA negative were still positive by PCR and all samples with PCR negative were negative detected by CPA while some samples that were negative by CPA were still positive detected by PCR (20%). In HIV/AIDS population, there were significant correlation between CPA and PCR TB LMK FKUI which all positive result of CPA (94.1%) were also PCR positive but 30% of CPA negative were still CPA positive and almost all of PCR negative (93.3%) were CPA negative.

Conclusion: There were significant correlation between CPA and PCR TB LMK FKUI in ditected of M.tuberculosis in sputum of suspected pulmonary TB in populations of non HIV/AIDS patients and HIV/AIDS patients."

Background: Chronic pulmonary aspergillosis (CPA) is a progressive, destructive lung disease mainly caused by Aspergillus fumigatus infection. The disease can be a complication of tuberculosis (TB) infection and cause significant morbidity and mortality. Diagnosis of CPA is still challenging because the clinical symptoms are not typical, and there are no fast and accurate diagnostic tools. Detection of IgG-specific Aspergillus using the immunochromatography (ICT) method is a quick and simple test to assist CPA diagnosis. The study aimed to determine the correlation between the ICT Aspergillus test and the clinical and radiological characteristics of CPA in TB-related patients.

Method: This cross-sectional study was carried out in April 2019-July 2023 and was part of a previous study on CPA diagnosis in Indonesia. All sera of CPA patients were examined at the Clinical Parasitology Laboratory, Faculty of Medicine Universitas Indonesia for ICT Aspergillus detection, followed by analysis of the study results.

Result: Twenty-nine of the 54 patient sera showed positive results of ICT Aspergillus. There were more female (76%) than male patients, with the majority aged 30–60 years (74%). The most common clinical symptoms were fatigue (57%), cough ≥3 months (42%), hemoptysis (41%), shortness of breath (24%), and chest pain (20%). The most common comorbidities were diabetes mellitus (20%), cardiovascular diseases (11%), and COPD (9%). The dominant of radiological features were cavities (94%), followed by infiltrates (72%), and pleural thickening (55%). The statistical analysis showed a significant correlation between positive ICT Aspergillus results and radiological features, including infiltrates, paracavity fibrosis, fibrosis, pleural effusion, consolidation, and bronchiectasis. However, the ICT Aspergillus did not show statistical significance with clinical characteristics.

Conclusion: The ICT Aspergillus detection in this study showed positive results of 54%. There was a significant correlation between ICT Aspergillus positive result with radiology features, but no significant correlation with clinical characteristics."

"Latar Belakang dan Tujuan: Prevalensi tuberkulosis di Indonesia menduduki peringkat kedua terbanyak setelah India dan peran diagnosis cepat serta akurat sangatlah penting. Sejak tahun 2014 pemeriksaan laboratorium berbasis amplifikasi asam nukleat GenXpert MTB/RIF telah diadopsi dalam pedoman nasional penanggulangan TB paru BTA negatif karena dalam 2 jam dapat lebih akurat mendeteksi basil tahan asam dibandingkan dengan apusan sputum BTA konvensional. Harga yang mahal dan ketersediaan yang terbatas membuat perlunya alternatif lain untuk pemeriksaan ini. Penelitian ini bertujuan untuk membandingkan gambaran radiografi toraks GenXpert MTB/RIF pada pasien tersangka TB paru BTA negatif. Metode: Uji komparasi dengan pendekatan potong lintang membandingkan gambaran radiografi toraks tipikal, atipikal dan bukan TB pada 44 subyek dengan hasil GenXpert MTB/RIF positif dan negatif 22 subyek per kelompok. Analisis berdasarkan adanya komorbiditas HIV, DM, terapi imunosupresan jangka panjang juga dilakukan. Hasil: Terdapat kesesuaian antara gambaran radiografi toraks dengan hasil pemeriksaan genXpert MTB/RIF pada subyek dengan BTA sputum negatif, dengan nilai kappa 0,59 moderate, sensitivitas 81,8 dan spesifisitas 77,3, yang menguat pada kelompok tanpa komorbiditas kappa 0,71l; sensitivitas 87,5, spesifisitas 83,3, serta berkurang pada kelompok dengan komorbiditas kappa 0,464; sensitivitas 81,8 ; spesifisitas 71,4.

Background and Purpose: Indonesia rsquo s tuberculosis prevalence is currently ranked second highest in the world after India. Therefore, the role of fast and accurate diagnosis is very important. After 2014, a nucleic acid amplification test GenXpert MTB RIF is implemented for negative sputum smear tuberculosis, due to its ability to diagnose tuberculosis within 2 hours with higher accuracy compared to conventional smear. Due to its high cost and lack of availability, an alternative for diagnostic tools should be sought. This study objective is to compare chest radiography using WHO ISTC criteria based on typical and atypical lesion, with GenXpert MTB RIF on subjects who are suspected tuberculosis, with negative sputum smear.

Methods: Comparative cross sectional study to compare chest radiography using WHO ISTC criteria based on typical and non typical TB among 44 subjects suspected tuberculosis infection with negative sputum smear, among groups with positive and negative GenXpert each 22 subjects. Analysis is also performed on subjects with and without comorbidities HIV, DM, long term immunosuppressive therapy.

Results: We found moderate agreement with kappa value 0,59 moderate, sensitivity 81,8 and specificity 77,3, and showing increased value in group without comorbidities kappa 0,71l sensitivity 87,5, specificity 83,3, and decreased value in group with comorbidities kappa 0,464 sensitivity 71,4 specificity 75. Radiographic lesions most frequently found in positive GenXpert group are upper field infiltrate 77,3, nodules 40,9, and cavities 36,4, with greater proportion compared with negative group, and statistically significant p<0,05.

Conclusion: Compared with GenXpert MTB RIF, chest radiography shows good sensitivity and specificity, so it is still potential as cost effective diagnostic modality especially in peripheral areas in Indonesia. "

Introduction: Chronic pulmonary aspergillosis (CPA) is common in post TB patients. Faster and more sensitive Aspergillus serological examination is necessary for CPA diagnosis. This study compared automated ELISA and immunochromatography test for Aspergillus specific antibody detection in post pulmonary TB patients.

Method: This cross-sectional study is part of previous research on CPA diagnosis in tuberculosis. Patient’s sera were tested with automated ELISA and immunochromatography test. The results were compared to CPA diagnosis to obtain diagnostic performances. The agreement between tests was analyzed with Cohen’s kappa.

Result: There were 68 previous TB patients with median age 34,5 (17-72) years old. CPA was diagnosed in 24 patients (35,3%). The positive result of automated ELISA and immunochromatography test were 48,5% and 2,9%. Automated ELISA showed sensitivity of 97%, specificity of 75%, PPV of 66,7%, and NPV of 94,3%. The immunochromatography test showed sensitivity of 8,3%, specificity and PPV of 100%, and NPV of 66,7%. There was very low agreement between tests (kappa score: 0,062).

Conclusion: Automated ELISA Aspergillus specific IgG could be utilized for supporting CPA diagnosis in post TB patients, mainly in settings where resources are available. Immunochromatography test is applicable as an early screening tool for CPA detection in resource-constrained areas."
