Latar belakang: Aspergillus adalah jamur saprofit di alam dan mudah terhirup ke dalam saluran napas. Pada pasien dengan gangguan sistem imun, Aspergillus dapat menimbulkan gangguan kesehatan, termasuk penyakit aspergilosis paru invasif (API). Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) adalah penyebab COVID-19 yang dapat mengganggu imunitas lokal saluran napas. Kondisi tersebut memudahkan Aspergillus melakukan invasi ke jaringan paru dan menyebabkan COVID- 19-associated pulmonary aspergillosis (CAPA). Deteksi galaktomanan (GM) serum dapat membantu diagnosis CAPA. Penelitian ini bertujuan untuk mengetahui hubungan GM serum pasien COVID-19 dengan kejadian CAPA. Metode: Penelitian potong lintang ini dilaksanakan pada Agustus 2022-Juni 2023. Data GM serum diperoleh dari Laboratorium Parasitologi Klinik FKUI, sedangkan data klinis dan radiologis pasien COVID-19 diperoleh dari salah satu rumah sakit swasta di Jakarta. Analisis statistik dilakukan untuk mencari hubungan GM serum dengan diagnosis CAPA. Hasil: Proporsi hasil GM serum positif didapatkan pada 24 (43,6%) dari 55 pasien COVID-19 yang diteliti. Dari 22 pasien probable CAPA, penyakit penyerta terbanyak adalah hipertensi (51,7%), diikuti IMT overweight (77,27%). Gejala klinis terbanyak adalah batuk (95,45%), demam (86,36%) dan sesak napas (68,18%). Faktor risiko CAPA belum dapat ditentukan dalam penelitian ini. Hasil GM serum tidak menunjukkan hubungan secara statistik dengan kejadian CAPA. Kesimpulan: Deteksi GM serum pada 55 pasien COVID-19 menunjukkan hasil positif 43,6%. Pada penelitian ini tidak ditemukan hubungan antara GM serum dengan kejadian CAPA. ...... Background: Aspergillus, a ubiquitous saprophytic fungus, is easily inhaled into the respiratory tract. In patients with impaired immune systems, Aspergillus can cause health disorders, including invasive pulmonary aspergillosis (IPA). Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of COVID-19, which can disrupt local airway immunity. These conditions make Aspergillus easier to invade lung tissue and cause COVID-19-associated pulmonary aspergillosis (CAPA). Serum galactomannan (GM) detection can support the diagnosis of CAPA. This study aimed to determine the relationship between the serum GM of COVID-19 patients and the diagnosis of CAPA. Methods: This cross-sectional study was conducted in August 2022-June 2023. Serum GM data were obtained from the Clinical Parasitology Laboratory FMUI, while clinical and radiological data of COVID-19 patients were obtained from a private hospital in Jakarta. Statistical analysis was conducted to determine the relationship between serum GM and CAPA diagnosis. Results: The proportion of positive serum GM results was found in 24 (43.6%) of the 55 COVID-19 patients studied. Furthermore, of the 22 probable CAPA patients, the most comorbid disease were hypertension (51.7%), followed by overweight BMI (77.27%). The most clinical symptoms were cough (95.45%), fever (86.36%) and shortness of breath (68.18%). The risk factors of CAPA could not be determined in this study. Serum GM results showed no statistical association with the incidence of CAPA. Conclusion: Detection of serum GM in 55 COVID-19 patients showed a positive result of 43.6%. There was no association between serum GM and CAPA events in this study.

Latar Belakang : Asma merupakan penyakit inflamasi kronik saluran napas dengan fungsi bersihan mukosilier yang menurun, maka itu bentuk matur dari spora Aspergillus fumigatus bisa tumbuh dan membuat sensitisasi Aspergillus yang merupakan kondisi awal aspergillosis paru pada asma dan dapat berkembang menjadi Allergic Bronchopulmonary Aspergillosis (ABPA). Penegakkan diagnosis aspergillosis paru didapatkan jika reaksi hipersensitisasi terhadap antigen A.fumigatus positif. Metode : Penelitian ini menggunakan metode potong lintang pada 86 pasien asma yang berobat ke RSUP Persahabatan dengan nilai Asthma Control Test (ACT) ≤ 24. Subjek penelitian dibagi 2 kelompok berdasarkan sensitisasi Aspergillus. Penilaian aspergillosis paru menggunakan pemeriksaan Imunoglobulin E (IgE) spesifik A.fumigatus. Kriteria diagnosis ABPA yang digunakan pada penelitian ini menggunakan kriteria International Society of Human and Animal Mycology (ISHAM) yaitu dua kriteria obligatory (IgE spesifik A.fumigatus dan IgE total) serta 3 kriteria tambahan (IgG spesifik A.fumigatus, eosinofil total, gambaran foto toraks). Pemeriksaan fungsi paru dilakukan pada penelitian ini termasuk spirometri, kapasitas difusi paru karbon monoksida (DLCO) dan nitrit oksida udara ekspirasi (FeNO). Hasil : Proporsi pasien asma tidak terkontrol yang memiliki aspergillosis paru didapatkan 3,5% (3/86) sedangkan proporsi ABPA didapatkan 1,1% (1/86). Terdapat faktor-faktor yang memengaruhi aspergillosis paru pada asma tidak terkontrol, diantaranya adalah nilai IMT (p=0,77), riwayat merokok (p=0,86) dan riwayat TB paru (p=0,03).. Karakteristik imunologi didapatkan nilai median IgE total pada subjek dengan aspergillosis paru 465(22-1690) IU/ml dan nilai median hitung total eosinofil 380 (0-770) sel/µl. Dari penilaian spirometri pada subjek aspergillosis paru didapatkan nilai median KVP 1630(950-2150) ml, nilai rerata KVP%prediksi 70±33,71%, nilai VEP1 1150(470-1240) ml, nilai median VEP1% prediksi 54(24-76)%, nilai rerata VEP1/KVP 59,33±14,57)% serta nilai rerata DLCO 84,67±24,66%. Nilai median FeNO pada asma tidak terkontrol dengan aspergillosis paru pada penelitian ini didapatkan 32 (12-45) ppb. Kesimpulan : Penegakkan diagnosis aspergillosis paru pada pasien asma tidak terkontrol harus dilakukan sejak awal, terutama pada pasien dengan riwayat TB  paru. Hal tersebut dapat mencegah aspergillosis paru pada asma tidak terkontrol berkembang menjadi penyakit ABPA serta kerusakan paru yang permanen. ......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.

ABSTRAK
Ruang Lingkup dan Cara Penelitian: Aspergillus merupakan jamur yang dapat menyebabkan penyakit pada manusia. Salah satu di antaranya adalah alergi, yang mempunyai manifestasi klinik asma bronkial. Di Indonesia peran Aspergillus dalam menimbulkan serangan asma bronkial belum diketahui. Untuk itu dilakukan pemeriksaan sputum terhadap adanya Aspergillus pada 75 orang penderita asma dan 62 orang sehat. Pengambilan sputum dilakukan pada saat serangan dan satu minggu sesudahnya. Sputum dibatukkan ke dalam cawan Petri steril; dilakukan pemeriksaan langsung dan biakan. Biakan dianggap positif bila tumbuh jamur Aspergillus satu koloni atau lebih. Hasil pemeriksaan kelompok penderita asma pada saat serangan dibandingkan dengan hasil pemeriksaan satu minggu sesudah serangan. Juga dibandingkan antara kelompok asma dan kelompok sehat. Selain itu dilakukan pemeriksaan tes imunodifusi dengan antigen Aspergillus untuk mencari zat anti terhadap Aspergillus.

Hasil dan Kesimpulan: Hasil pemeriksaan sputum pada 53 orang (yang kembali) penderita asma pada saat serangan dan satu minggu sesudahnya memberi hasil 27 orang positif pada saat serangan dan negatif sesudahnya. Pengujian statistik menunjukkan adanya ketergantungan antara Aspeuillus dan serangan asma (p<0,01). Tujuh puluh lima orang penderita asma diperiksa pada saat serangan dengan cara langsung, 22 orang positif (23%) dan dengan biakan 45 orang positif (60%). Pada orang sehat dengan cara yang sama didapatkan 6 orang (9,6%) dan 9 orang (14,5%) positif. Uji statistik menunjukkan adanya hubungan antara serangan asma dan Aspergillus (p<0,01). Odds ratio 8,8 menunjukkan Aspergillus memang mampu menyebabkan penyakit. Perbandingan hasil pemeriksaan sputum satu minggu sesudah serangan dan orang sehat menunjukkan adanya perbedaan bermakna, hal ini berarti bahwa satu minggu sesudah serangan belum menggambarkan keadaan normal. Hasil pemeriksaan tes imunodifusi menunjukkan bahwa sebagian besar tidak ada invasi Aspergillus ke dalam jarigan.

Kasus aspergilosis paru kronik (APK) yang disebabkan Aspergillus sp. semakin meningkat seiring dengan meningkatnya frekuensi infeksi tuberkulosis (TB) paru sebagai faktor risiko. Diagnosis APK masih menjadi tantangan karena gejala klinis, pemeriksaan radiologi, maupun laboratorium tidak khas. Untuk menetapkan diagnosis APK diperlukan pemeriksaan laboratorium mikologi, termasuk uji serologi. Hasil pemeriksaan imuno-diffusion test (IDT) Aspergillus dengan crude antigen kurang optimal dan IgG Aspergillus ELISA menggunakan antigen galaktomanan yang termasuk antigen sel T independent sehingga tidak mendukung switching isotipe antibodi. Oleh sebab itu, diperlukan penelitian lain untuk mendapatkan prosedur yang lebih baik dalam menetapkan diagnosis APK. Tujuan penelitian ialah mengetahui pola respon IgG terhadap kombinasi empat protein 16 kD, 18-20 kD, 22 kD, dan 30 kD antigen Aspergillus dengan metode Western Blot. Potensi diagnostik dari kombinasi protein 16 kD, 18-20 kD, 22 kD, dan 30 kD antigen Aspergillus dengan metode Western Blot terhadap nilai konsensus positif dan negatif APK berdasarkan 2 metode pemeriksaan yaitu biakan jamur dan IgG anti galaktomanan sebagai baku emas didapatkan nilai sensitivitas dan spesifisitas sebesar 74% dan 96%. Deteksi IgG Aspergillus metode Western Blot menunjukkan antigen dominan berat molekul 16 kD dan 18-20 kD. Kesimpulan uji IgG Aspergillus Western Blot memiliki potensi diagnostik lebih baik dibanding uji IgG Aspergillus ELISA. ......Chronic pulmonary aspergillosis (CPA) caused by Aspergillus sp. potentially increases with the increasing frequency of pulmonary tuberculosis (TB) as a risk factor. Diagnosis of CPA is still a challenge because clinical symptoms, radiological examination, and laboratory are  not specific. The diagnosis of CPA needs to be performed by specific mycological examination, including serology test. The result of the Aspergillus immunodiffusion test (IDT) with crude antigen is sub optimal and Aspergillus IgG ELISA method uses galactomannan antigens that are independent T cell antigens, so cant support switching of isotype antibodies. Therefore, other study is needed to get a better procedure in determine the CPA diagnostic. The study aimed to determine the IgG responses with a combination of  Aspergillus proteins (16 kD, 18-20 kD, 22 kD, and 30 kD) with Western Blot method. Diagnostic potential of the Aspergillus protein combination (16 kD, 18-20 kD, 22 kD, and 30 kD) with Western Blot method on positive and negative consensus values of CPA based on two examination methods are fungus culture and anti-galactomannan IgG as gold standard are obtained sensitivity and specificity of 74% and 96%. From the Aspergillus Western Blot IgG test, dominant antigens obtained were molecular weights of 16 kD and 18-20 kD. The conclusion is Aspergillus specific IgG test with Western Blot method has better diagnostic potential than the  anti-galactomannan IgG ELISA method.

The clinical symptoms of CPA can resemble with PTB, making it difficult to distinguish. The diagnosis of CPA is determined by the consensus based on clinical symptoms, radiological features, and mycological results. Antibody detection with Aspergillus- specific immunoglobulin G (IgG) using the Enzyme-linked immunosorbent assay (ELISA) method can contribute to CPA diagnosis. This study aims to determine the clinical characteristics, Aspergillus-specific IgG detection, and the prevalence of CPA in prior TB patients at several hospitals in Jakarta. Method: This prospective cross-sectional study was conducted in April 2019 - February 2020. Patients recruitment was carried out by consecutive sampling method. Subjects were prior TB patients at Persahabatan National Respiratory Referral Hospital and Graha Permata Ibu Hospital. Detection of Aspergillus- specific IgG and fungal cultures from sputum were carried out in the Laboratory of the Parasitology Department, FMUI. Results: Of 97 patients recruited according to inclusion criteria, 66 patients (68%) were male and the mean age was 51.8 ± 13.6 years. The clinical symptoms of more than 3 months were fatigue (38.4%), shortness of breath (34.02%), cough (30.93%), hemoptysis (27.84%), weight loss (23, 71%), and chest pain (19,6%). Radiological features associated with CPA were ectasis (57.8%), cavity (27.8%), pleural thickening (26.8%), para-cavitary fibrosis (18.6%), and fungal ball (6.2%). The Aspergillus-specific IgG positive were reported in 51 patients (52.6%), whereas Aspergillus sputum cultures were found in 43 patients (44.3%). Based on the analysis of those examinations, the diagnosis of CPA was determined in 28 patients (28.9%). Conclusion: The detection of Aspergillus-specific IgG in 97 prior TB patients showed the positive results in 51 patients (52.6%). The clinical symptoms more than three months were fatigue, shortness of breath, cough, hemoptysis, and weight loss. The radiological features related to CPA were ectasis, cavitary lesions, pleural thickening, paracavitary fibrosis, and fungal ball. The prevalence of CPA based on those examinations was 28.9%.
