Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) merupakan coronavirus baru, pertama kali terdeteksi di Wuhan, Cina. Tingginya jumlah kasus dan cepatnya proses infeksi membutuhkan deteksi cepat dan akurat untuk menegakan diagnosis COVID-19. Studi bertujuan memperoleh sensitivitas dan spesifisitas uji serologi IgG SARS-CoV-2 Architect dibandingkan dan RT-PCR pada pasien COVID19. Studi ini menggunakan pendekatan potong lintang uji diagnostik, dengan menggunakan 128 pasien yang diperoleh di RSUP Persahabatan. Studi ini berlangsung sejak bulan April sampai Juli 2021 di RSUP Persahabatan. Sampel berupa swab nasofaring diambil dari pasien untuk diperiksa dengan uji RT PCR dan darah untuk uji serologi menggunakan Architect ® i2000SR Abbott. Hasil uji sensivitas Architect sebesar 27.37% (18.72%-37,48%) dan spesifisitas 63.64% (45,12% - 79,60%). NPV 23,33% dan PPV 68,42%. Kesimpulan: Secara keseluruhan uji serologi SARS-CoV-2 IgG Architech memiliki sensitivitas dan spesifisitas yang rendah dibanding dengan RTPCR. Architect dapat digunakan untuk screening, dapat digunakan pada fase akut, hasil negatif perlu dikonfirmasi dengan RT-PCR. Tidak ada hubungan antara Ct-value RTPCR dengan derajat keparahan COVID-19, dan terdapat hubungan antara titer Architect dengan derajat keparahan COVID-19. Tidak ada hubungan onset COVID-19 dengan hasil pemeriksaan RT-PCR dan Architect ......Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is a new coronavirus, which was first detected in Wuhan, China. The high number of cases and the rapid process of infection require fast and accurate detection to establish the diagnosis of COVID-19. The study aimed to obtain the sensitivity and specificity of the SARS-CoV2 Architect IgG serological test compared to RT-PCR in COVID-19 patients. This study used a cross-sectional approach to diagnostic testing, using 128 patients obtained from Persahabatan Hospital. This study took place from April 2021 to July 2021 at the Persahabatan Hospital. Nasopharyngeal swab samples were taken for RT-PCR and blood was drawn for serological testing using the Architect® i2000SR from Abbott.

ABSTRAK
Amebiasis merupakan penyakit yang umum yang banyak ditemukan di negara berkembang. Namun hanya sedikit yang bermanifestasi klinis menjadi kolitis amuba. Komplikasi yang paling sering dijumpai adalah abses hati amuba. Abses hati selain disebabkan oleh amuba dapat disebabkan oleh bakteri yang dikenal sebagai abses hati piogenik. Untuk dapat menegakkan penyebab abses hati yang disebabkan oleh amuba maka selain anamnesis dan pemeriksaan fisik, dibutuhkan pemeriksaan penunjang seperti pemeriksaan serologi antigen dan antibodi Entamoeba histolytica. Namun pada praktek klinis, jarang sekali pemeriksaan serologi ini dilakukan. Oleh karena itu penelitian ini mencoba untuk melihat profil pasien dengan dugaan abses hati amuba yang sampelnya dikirimkan ke laboratorium parasitologi FKUI untuk pemeriksaan antibodi E. histolytica serta menilai hubungan antara gejala klinis/tanda tersebut dengan hasil serologi. Sampel diambil dari data pasien RSCM yang sampelnya dikirimkan ke laboratorium parasitologi FKUI dengan dugaan abses hati berupa keluhan utama, pemeriksaan fisik dan hasil laboratorium dan hasil serologinya diambil dari hasil pemeriksaan ELISA antibodi Entamoeba histolytica. Hasil penelitian menunjukkan bahwa sebagian besar pasien yang positif serologi antibodi E. histolytica adalah pasien dari kelompok umur 26-45 tahun dan berjenis kelamin laki-laki. Sedangkan manifestasi klinis yang ditemukan pada pasien tersebut dari yang terbanyak adalah hepatomegali, klinis abses hati, nyeri perut, abdominal discomfort, berat badan turun, diare, muntah, efusi pleura dan mual. Yang memiliki hubungan signifikan dengan hasil serologi positif antibodi E. histolytica hanya hepatomegali. Dari data laboratorium ditemukan sebagian besar pasien memiliki hasil laboratorium normal. Namun ada beberapa pasien yang mengalami penurunan hemoglobin dan hematokrit, leukositosis, peningkatan laju endap darah serta peningkatan fungsi hati SGOT dan SGPT.

ABSTRACT
Amebiasis is a common disease that is found in many developing countries. Yet few have clinically manifested as amoebic colitis. The most common complication is an amoebic liver abscess. A liver abscess other than caused by amoeba can be caused by a bacterium known as a pyogenic liver abscess. To be able to determine the cause of liver abscess caused by amoeba, beside anamnesis and physical examination, laboratory examination such as serological antigen and antibody of Entamoeba histolytica is needed. However, in clinical practice, this serology test is hardly performed. Therefore, this study attempted to look at the profile of the patient with suspected liver abscess whose sample was sent to the parasitology laboratory FMUI for E. histolytica antibody examination and assess the association between the clinical signs with serology results. Samples data were taken from Cipto Mangunkusumo hospital patient whose samples were sent to parasitology laboratory FMUI with suspected liver abscess in the form of main complaint, physical examination and laboratory result. Additionally, serology result was taken from antibody of Entamoeba histolytica ELISA examination. The results showed that most of the positive serologically patients of E. histolytica antibodies were patients at the 26 45 age group and from male group. While the clinical manifestations found in these patients subsequently are hepatomegaly, clinical liver abscess, abdominal discomfort, weight loss, diarrhea, vomiting, pleural effusion and nausea. It is only hepatomegaly that has a significant association with serologic positive results for E. histolytica antibodies. From the laboratory data, most patients have normal laboratory results. However, there were some patients who experienced decreased of hemoglobin and hematocrit, leukocytosis, increased blood sedimentation rate and increased liver function of AST and ALT.

Pendahuluan: Pemeriksaan baku emas swab nasoorofaring dengan metode Reverse transcriptase polymerase chain reaction (RT-PCR) merupakan prosedur diagnostik yang dilakukan pada pasien dengan suspek COVID-19. Metode lain yang digunakan yaitu dengan pemeriksaan serologi yang mulai terbentuk dalam beberapa hari hingga minggu. Tujuan: Untuk mengetahui hubungan antara hasil swab nasoorofaring dan uji serologi terhadap luaran pasien COVID-19 dalam evaluasi masa rawat 14 hari Metode: Analisis observasional kohort retrospektif terhadap pasien COVID-19 yang dirawat di RS Rujukan Respirasi Nasional Persahabatan, Jakarta, Indonesia secara total sampling diperoleh dari bulan Maret 2020 sampai Mei 2020. Kami meninjau rekam medis 132 pasien dengan diagnosis probable case dan confirmed case COVID-19 yang memenuhi kriteria inklusi. Hasil: Sebanyak 132 pasien yang termasuk dalam penelitian ini, didominasi oleh laki-laki sebanyak 51,5% dengan usia rerata 50,23 tahun. Derajat pneumonia berturut-turut yaitu derajat ringan, sedang, dan berat (17,4%, 57,6%, dan 25,0%). Proporsi pasien dengan komorbid sebanyak 71,2%. Proporsi penggunaan alat bantu napas terbanyak yaitu penggunaan kanula hidung (69,7%) diikuti berturut-turut oleh Ventilator, non rebreathing mask dan high flow nasal cannule (13,6%, 9,1% dan 7,6%).. Proporsi kematian sebesar 18,3%, dengan proporsi kematian pada confirmed case sebanyak 21,3% dan probable case sebanyak 19,3%. Tingkat kematian pada confirmed case berkorelasi terhadap jenis kelamin laki-laki (p =0,009), derajat pneumonia berat (p=0,000), penggunaan alat bantu napas bukan kanula hidung (p=0,000) dan komorbid (p=0,021). Tingkat kematian pada probable case berkorelasi dengan derajat pneumonia berat (p=0,000), penggunaan alat bantu napas bukan kanula hidung (p=0,000). Kesimpulan: Kombinasi penggunaan swab nasoorofaring dan hasil uji serologi dapat memprediksi luaran pasien COVID-19 dalam evaluasi masa rawat 14 hari. Derajat pneumonia berat dan penggunaan alat bantu napas bukan kanula hidung merupakan prediktor buruk terhadap luaran pasien COVID-19. ......Introduction: Reverse transcriptase polymerase chain reaction (RT-PCR) to detect SARS- CoV-2 is a gold standard method in a patient with suspected COVID-19 and achievable by means of nasopharyngeal and oropharyngeal swab. Serological test is another method to detect the antibody which is produced in a several days or week. Aims: To determine the association between nasooropharyngeal swab and serological test to predict the mortality of COVID-19 patient after 14-days admission. Methods: We performed an observational retrospective cohort analysis of COVID-19 patients treated at National Respiratory Referral Hospital Persahabatan Jakarta, Indonesia. Subjects by means of total sampling were COVID-19 patients between March to May 2020. We reviewed the medical records of 132 patients categorized as probable and confirmed cases whom met the inclusion criteria. Their 14-days course of the treatment were observed. Results: We included 132 patients, which dominated by males (51.5%) with mean age of 50.23 years old. Cases were mild pneumonia, moderate pneumonia, and severe pneumonia (17.4%, 57.6%, and 25.0%, respectively). Most patients presented with comorbidities (71,2%). Most patients required oxygen supplementation by nasal cannula (69.7%), followed by mechanical ventilator, non-rebreathing mask, and high flow nasal cannula (13.6%, 9.1%, and 7.6%, respectively). Patient deaths were 18.3%, including 21.3% among confirmed cases and 19.3% among probable cases. Mortality among confirmed case were correlated with male sex (p=0.009), severe pneumonia (p=0.000), supplemental oxygen delivery requiring device other than nasal cannula (p=0.000), and comorbidities (p=0.021). Mortality among probable cases were correlated with severe pneumonia (p=0.000), and supplemental oxygen delivery requiring device other than nasal cannula (p=0.000). Conclusions: Combination of nasooropharyngeal swab and serological test results predicted the 14-days outcomes of COVID-19 patients. Severe pneumonia and supplemental oxygen delivery requiring device other than nasal cannula were predictors of poor COVID-19 outcomes as observed from our study.

Indonesia merupakan negara dengan beban TB terbesar kedua di dunia. Prevalensi infeksi penyerta jamur paru juga tinggi, salah satunya aspergilosis paru kronik (APK). Alat diagnostik yang baik dan mudah digunakan sangat diperlukan untuk menunjang diagnosis APK, namun data terkait hal tersebut di Indonesia masih terbatas. Penelitian ini bertujuan untuk mengetahui nilai performa diagnostik deteksi antibodi spesifik Aspergillus berbasis ELISA manual dan otomatis pada pasien TB paru. Penelitian ini merupakan uji diagnostik untuk membandingkan hasil deteksi antibodi spesifik Aspergillus berbasis ELISA menggunakan metode manual dan otomatis dari sera pasien TB paru yang diperiksa di Laboratorium Parasitologi FKUI. Dari 62 subjek yang memenuhi kriteria inklusi, 56,5% pasien adalah perempuan. Median usia pasien adalah 34 tahun dengan nilai minimum 16 dan nilai maksimum 72. Proporsi hasil positif ELISA manual adalah 12,9%, sedangkan proporsi hasil positif ELISA otomatis adalah 29%. Metode ELISA manual memiliki nilai performa diagnostik 20% untuk sensitivitas, 90,48% untuk spesifisitas, 61,5% untuk nilai duga positif, dan 59,79% untuk nilai duga negatif. Adapun ELISA otomatis memiliki nilai performa diagnostik 70% untuk sensitivitas, 90,48%untuk spesifisitas, 84,83% untuk nilai duga positif, dan 79,86% untuk nilai duga negatif. Kemampuan diagnostik ELISA manual tidak sebaik otomatis, namun dapat dipertimbangkan sebagai alat diagnosis penapisan yang lebih mudah diakses, khususnya di daerah dengan sumber daya terbatas. Perlu dilakukan penelitian lanjutan mengenai cut-off ELISA manual yang sesuai untuk populasi Indonesia. ......Indonesia is a country with the second largest TB burden in the world. The prevalence of pulmonary fungal infections is also high, one of which is chronic pulmonary aspergillosis (CPA). A good and easy-to-use diagnostic tool is needed to aid CPA diagnosis. This study aims to determine the diagnostic performance value of Aspergillus-specific antibody detection based on manual and automatic ELISA on pulmonary TB patient’s serum carried out at Parasitology Laboratory FMUI. This diagnostic test study compared the results of Aspergillus-specific antibody detection in pulmonary TB patient’s sera based on ELISA using manual and automatic methods. Of the 62 subjects who met the inclusion criteria, 56.5% of the patients were women. The median age of the patients was 34 years with a minimum value of 16 and a maximum value of 72. The proportion of positive results for manual ELISA was 12.9%, while the proportion of positive results for automatic ELISA was 29%. Manual ELISA has a diagnostic performance value of 20% for sensitivity, 90.48% for specificity, 61.5% for a positive predictive value, and 59.79% for a negative predictive value. Meanwhile, automatic ELISA has a diagnostic performance value of 70% for sensitivity, 90.48% for specificity, 84.83% for a positive predictive value, and 79.86% for a negative predictive value. Manual ELISA diagnostic capabilities are not as good as automated one but can be considered as a screening diagnostic tool as it is more accessible, especially in areas with limited resources. It is necessary to study the appropriate cut-off on manual ELISA Indonesian population.
