Introduction: Indonesia has high tuberculosis (TB) burden. The resulting lung damage underlies chronic pulmonary aspergillosis (CPA) development. CPA is diagnosed in patients with evidence of Aspergillus involvement as one of its criteria. Taking into account the limitations of culture, ELISA antibody detection becomes alternative modality. This study aims to compare diagnostic performance between manual and automated ELISA for Aspergillus-specific IgG in patients with treated TB. Method: This cross-sectional study compares Aspergillus-specific IgG test using Bordier manual ELISA and Immulite automated ELISA on sera from patients with treated TB. Diagnostic performance was compared in positive test proportion, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV). Result: There are 68 subjects, with median age of 34,5 years, elderly subjects proportion of 11,76%, male proportion of 42,65%. Positive results proportion from Aspergillus-specific IgG manual and automated ELISA are 13,24% and 48,53%, respectively. Manual ELISA shows 20,83% sensitivity, 90,91% specificity, 55,56% PPV, 67,80% NPV. Automated ELISA shows 91,67% sensitivity, 75% specificity, 66,67% PPV, 94,29% NPV. Conclusion: Technical and diagnostic performance of automated ELISA Aspergillus-specific IgG test is better than manual ELISA, but choosing diagnostic modality needs consideration on factors such as affordability, accessibility, and accuracy according to the needs and available resources."

"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: Asthma is a chronic airway inflammation with decrease of mucocilliary clearance. The mature form of Aspergillus fumigatus spores could grow in this condition and caused an Aspergillus sensitization as an early progression to allergic bronchopulmonary aspergillosis (ABPA). Pulmonary aspergillosis could be diagnosed from a hypersensitivity reaction to the A. fumigatus antigen.

Methods : This cross-sectional study included 86 asthma patients with Asthma Control Test ACT score ≤ 24 and treated at Persahabatan Hospital Jakarta, Indonesia. Pulmonary aspergillosis was examined using specific immunoglobulin E (IgE) assay of A. fumigatus. The ABPA diagnostic in this study used the International Society of Human and Animal Mycology (ISHAM) criteria, which included two obligatory criteria (A. fumigatus-specific IgE and total IgE) and three additional criteria (A. fumigatus-specific IgG, blood eosinophil count, and thoracic x-ray). Lung function were examined using spirometry, diffusing capacity for carbon monoxide (DLCO), and fraction of exhaled nitric oxide (FeNO).

Results: Uncontrolled asthma patients who had pulmonary aspergillosis was 3.5% (3/86) while the proportion of ABPA was 1.1% (1/86).  A history of prior pulmonary tuberculosis (TB) was correlated with aspergillosis in uncontrolled asthma patients (p=0.03). The median value of total IgE and blood eosinophil count in pulmonary aspergillosis subjects was 465 (22-1690) IU/mL and 380 (0-770) cells/µL, respectively. Spirometry results of pulmonary aspergillosis subjects were median FVC 1630 (950-2150) ml, mean predicted FVC% predicted value 70±33.71%, mean FEV1 1150 (470-1240) ml, median predicted FEV1% 54 (24-24)%, mean FEV1/FVC 59.33±14.57%, and mean DLCO 84.67±24.66%. The median FeNO in uncontrolled asthma with pulmonary aspergillosis in this study was 32 (12-45) ppb.

Conclusion: Diagnosis of pulmonary aspergillosis in patients with uncontrolled asthma should be carried out early, especially in patients with a history of pulmonary TB. This would prevent pulmonary aspergillosis in uncontrolled asthma from developing into ABPA disease and permanent lung damage."

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."

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."
