Latar Belakang: Penelitian mengenai petanda inflamasi akut terkait pajanan uap las pada pekerja las sudah banyak dilakukan. Akan tetapi, tidak semua penelitian tersebut sepakat terjadi perbedaan jumlah petanda inflamasi akut sesudah terpajan uap las. Penelitian ini ingin mengetahui apakah terjadi perbedaan jumlah petanda inflamasi akut akibat pajanan uap las dengan sel netrofil mukosa hidung sebagai petanda inflamasinya. Metode:Pada penelitian longitudinal ini, 110 pekerja di sebuah perusahaan pembuat knalpot diperiksa jumlah sel netrofil mukosa hidungnya sebelum dan sesudah terpajan uap las serta diukur kadar logam Kromium, Besi, Mangan, dan Aluminium dalam darah pada 40 pekerja diantaranya. Dilakukan pengukuran kadar logam Cr, Fe, Mn, dan Al di lingkungan kerja untuk menilai kadar pajanan. Hasil:Pengukuran lingkungan menunjukkan kadar Kromium, Besi, Mangan, dan Aluminium udara berada di bawah Nilai Ambang Batas. Sel netrofil sediaan apus sebelum dan sesudah terpajan uap las 8 jam sama – sama berjumlah 2 sel/10 lpk (p = 0,233). Pada penelitian ini juga ditemukan kadar dalam darah logam Cr sebesar 1,03 µg/l; logam Fe sebesar 283.787,73 µg/l; logam Mn sebesar 14,96 µg/l; dan logam Al sebesar 25,68 µg/l. Kesimpulan:Tidak ditemukan perbedaan jumlah sel netrofil mukosa hidung yang bermakna secara statistik akibat pajanan uap las. ......Background and Objective: Many studies about acute inflammation marker regarding metal fume exposure have been conducted but not all agree that metal fume exposure will raise acute inflammation response. One of the acute inflammation markers is nasal mucous neutrophil and this study was conducted to investigate the difference of neutrophil count after being exposed to metal fume as acute inflammation response. Methods: This study used a longitudinal design with 110 welders as subjects. Nasal mucous neutrophil data was collected before and after 8 hours metal fume exposure. Metal fume (i.e. Chromium, Iron, Manganese, and Aluminum) exposure in the work place was measured with AAS while blood metal level in 40 subjects among them was with ICP-MS. Results: Chromium, Iron, Manganese, and Aluminum fume level in the work place was under Threshold Limit Value while Chromium, Iron, Manganese, and Aluminum blood level was 1,03 µg/l; 283.787,73 µg/l; 14,96 µg/l; and 25,68 µg/l respectively.Neutrophil count before and after 8 hours metal fume exposure didn’t show any difference with statistically significance (p = 0,233) Conclusions: There was no statistical significant increase of nasal mucous neutrophil regarding metal fume exposure

Latar Belakang : Non-alcoholic fatty liver disease (NAFLD) adalah penyakit hati kronik yang ditandai dengan akumulasi lemak berlebihan di hati. Elastografi Transien (ET) dan metode Controlled Attenuation Parameter (CAP) merupakan metode pemeriksaan non-invasif untuk menilai derajat fibrosis dan steatosis, namun tidak tersedia di seluruh rumah sakit di Indonesia. Rasio Neutrofil Limfosit (RNL) merupakan penanda peradangan sederhana yang berpotensi memprediksi luaran penyakit. Tujuan : Mengetahui nilai diagnostik RNL sebagai indikator derajat keparahan steatosis dan fibrosis NAFLD. Metode : Penelitian ini adalah studi potong lintang menggunakan data sekunder dari data rekam medis tahun 2016-2018. Analisis statistik deskriptif dan analitik berupa uji korelasi, Receiver Operating Curve (ROC) dan Area Under The Curve (AUC) dipakai untuk mengetahui luaran studi. Hasil : Dari 106 subjek penelitian, kebanyakan pasien adalah perempuan (62,3%) berusia rata-rata 57,29 tahun dan menderita sindrom metabolik (77,4%). Sebagian besar pasien memiliki derajat steatosis sedang-berat (66%) dengan rerata ET 6,14 (2,8-18,2). Terdapat korelasi antara nilai CAP (r=0,648; p<0,001) dan ET (r=0,621; p<0,001) dengan RNL. Penggunaan RNL untuk menilai derajat steatosis sedang-berat memiliki titik potong 1,775 dengan sensitivitas, spesifisitas, NDP dan NDN sebesar 81,5%, 80,6%, 89,1%, dan 69,1%; titik potong 2,150 untuk menilai fibrosis signifikan dengan sensitivitas, spesifisitas, NDP dan NDN berurutan sebesar 92.3 %, 87.5%, 70.6%, dan 97.2%. Simpulan : RNL memiliki korelasi positif terhadap derajat steatosis dan fibrosis dengan sensitivitas dan spesifisitas yang tinggi. ......Introduction : Non-alcoholic fatty liver disease (NAFLD) is a chronic inflammatory disease with excessive fat accumulation in the liver. Transient Elastography (TE) with Controlled Attenuation Parameter (CAP) is a device and method to examine the degree of fibrosis and steatosis. However, this device is not widely available across Indonesia. Neutrophil and Lymphocyte Ratio (NLR) is a simple marker for inflammation which has a potency to predict disease outcome. Objective : To know the diagnostic value of RNL as the indicator of steatosis and fibrosis severity. Methods : This was a cross-sectional study using secondary data from the medical record, starting from 2016-2018 with the respective inclusion and exclusion criteria. A descriptive and analytic statistic, including correlation test, Receiver Operating Curve (ROC) and Area Under The Curve (AUC) were done to know the outcome of the study. Result: Out of 106 subjects, 62.3% patients were women with aged mean 57.29 years old and 77.4% had metabolic syndrome. Most patients had average-severe steatosis degree (66%) with the mean of ET mean 6.14 (2.8-18.2). There was a positive correlation between CAP and TE compared with NLR with r = 0.647 (p<0.001) and r = 0.621 (p<0.001) respectively. The use of NLR to assess moderate-severe steatosis has a cutoff point of 1.775 with sensitivity, specificity, PPV and NPV of 81,5%, 80,6%, 89,1%, and 69,1%; cutoff point 2,150 to assess significant fibrosis with sensitivity, specificity, PPV and NPV of 92.3 %, 87.5%, 70.6%, 97.2% respectively. Conclusion : NLR has a positive correlation with the degree of steatosis and fibrosis with high sensitivity and specificity.

[ABSTRAK
Latar belakang : Pada masa sekarang, reperfusi miokardium dengan trombolitik atau intervensi koroner perkutan primer ( IKPP) adalah terapi utama pada pasien yang mengalami IMA EST. Tujuan utama IKPP untuk mengembalikan patensi arteri epikardial yang mengalami infark dan mencapai reperfusi mikrovaskular secepat mungkin. Namun keberhasilan mengembalikan patensi dari arteri koroner epikardial setelah oklusi tidak selalu menjamin cukupnya reperfusi ke level mikrovaskular, yang disebut sebagai fenomena no reflow atau microvascular obstruction (MVO). Terdapat dua mekanisme yang berperan pada no reflow yaitu disfungsi mikrovaskular dan kerusakan intergritas mikrostruktur endotel. Kerusakan endotel dapat diakibatkan berbagai hal, diantara nya jejas reperfusi yang akan mengaktivasi netrofil. Netrofil teraktivasi akan mengeluarkan radikal bebas oksigen, enzim proteolitik dan mediator proinflamasi yang secara langsung menyebabkan kerusakan jaringan dan endotel. Trimetazidine adalah obat antiangina yang dapat menurunkan netrofil yang dimediasi oleh trauma jaringan setelah jantung mengalami iskemia. Akan tetapi belum diketahui secara luas pengaruh pemberian trimetazidine terhadap akumulasi netrofil pada kejadian IMA EST yang dilakukan tindakan IKPP. Metode : Sebanyak 68 pasien IMA EST yang menjalani IKPP dipilih secara konsekutif sejak Januari 2015 sampai Juni 2015 diambil saat masuk UGD, dilakukan pengambilan darah vena perifer untuk menghitung jumlah netrofil sebelum IKPP, kemudian pasien menjalani IKPP. Setelah 6 jam paska IKPP dilakukan pengambilan kembali darah vena perifer untuk menghitung kembali jumlah netrofil paska IKPP. Hitung netrofil diperiksa dengan Sysmex 2000i. Perhitungan statistik dinilai dengan SPSS 17. Hasil : Dari 68 subyek, dibagi menjadi 28 subyek pada kelompok yang diberikan trimetazidine dan 40 subyek yang diberikan plasebo. Tidak didapatkan perbedaan jumlah netrofil pada kelompok perlakuan dan kelompok kontrol baik sebelum maupun sesudah IKPP, netrofil pre IKPP pada trimetazidine vs plasebo 10.71 ± 3.263 vs 10.99 ± 3.083,nilai p:0,341. Nilai netrofil post IKPP pada trimetazidine vs plasebo 9.49 ± 3.135 vs 9.92 ± 3.463,nilai p:0,664. Kesimpulan : Tidak terdapat penurunan jumlah netrofil pasca pemberian trimetazidine pada pasien IMA EST yang menjalani IKPP.

ABSTRACT
Background Nowadays, reperfusion strategy, either with thrombolytic or Primary Percutaneous Coronary Intervention (PPCI), is the core treatment for Acute ST-Segment Elevation Myocardial Infarct (STEMI). The goal of PPCI is to restore the patency of infarcted epicardial artery and establish microvascular reperfusion as soon as possible so that necrotic myocardial area can be reduced. However, successful restoration of infarcted epicardial artery is not always followed by enough reperfusion to the microvascular part. Trimetazidine is an antianginal drug, can reduce neutrophil which was mediated by tissue trauma during ischemic heart condition. Trimetazidine is currently approved and widely known as antianginal drug which affect metabolism. Unfortunately, its influence over neutrophil accumulation in acute STEMI patients which undergo PPCI is not well understood. Method There were 68 consecutive-selected acute STEMI patients which undergo PPCI since January 2015 until Juni 2015. They were admitted in emergency department. Peripheral vein blood sampling was taken to measure neutrophil before PPCI was performed. Six hour after PPCI was conducted, another peripheral vein blood sampling was taken for another neutrophil measurement. Neutrophil measurement was performed with Sysmex 2000i. Statistical analysis was performed by using SPSS 17. Result Among 68 patients, divided in two groups, trimetazidine 28 patients and plasebo 40 patients. There were no differences amount of neutrophils in trimetazidine or plasebo group, before or after PPCI. Neutrophil pre PPCI in trimetazidine vs plasebo group 10.71 ± 3.263 vs 10.99 ± 3.083, p:0,341. Neutrophil post PPCI in trimetazidine vs plasebo group 9.49 ± 3.135 vs 9.92 ± 3.463, p:0,664.

Latar Belakang: Tuberkulosis paru (TB) masih menjadi salah satu penyebab morbiditas dan mortalitas di seluruh dunia. Dalam dua dekade terakhir penyakit TB resisten obat (TBRO) telah muncul sebagai ancaman bagi kesehatan masyarakat seluruh dunia. NGAL merupakan partikel granulosit neutrofil yang mengalami pematangan dan menjadi gelatinase. NGAL terlibat dalam kekebalan bawaan untuk menghalangi bakteri mengambil zat besi untuk pertumbuhan. Pada pasien dengan komorbid anemia akan terjadi penurunan kekebalan bawaan sehingga pada TBRO dengan anemia bakteri Mtb akan mendapat zat besi dari tubuh manusia untuk bereplikasi. Namun masih belum terdapat data kadar protein serum NGAL pada pasien TBRO dengan anemia. Metode : Penelitian ini merupakan penelitian analitik observasional menggunakan desain potong lintang yang dilakukan di poliklinik dan ruang rawat inap MDR RSUP Persahabatan pada bulan Juli-September 2023. Jumlah subyek penelitian adalah 73 pasien TBRO yang belum memulai pengobatan dengan anemia dan tanpa anemia yang memenuhi kriteria inklusi dan eksklusi. Sampel darah subyek diambil sebanyak 3cc. Serum darah diambil lalu disimpan dalam lemari es suhu -200C. selanjutnya dilakukan pemeriksaan ELISA teknik sandwich dan diambil kadar protein NGAL. Variabel lainnya diambil dari rekam medis RSUP Persahabatan. Hasil : Pada penelitian ini didapatkan pasien TBRO dengan anemia memiliki IMT yang menunjukkan tingkat malnutrisi yang bermakna (p:0,026, OR 2,9(1,1-7,5). Penelitian ini juga mengidentifikasi peningkatan jumlah neutrofil (p:0,002, OR 0,2(0,06-0,5) dan penurunan jumlah limfosit (p:0,006, OR (4,2 (1,4-9,8) pada kelompok pasien anemia, yang tercermin dalam NLR yang meningkat (p:0,028, OR 0,3(0,09-0,9). Hasil yang ditemukan juga menunjukkan bahwa pasien TBRO dengan anemia memiliki lesi paru yang lebih luas secara statistik (p:0,048, OR 2,7(0,9-7,3). Kadar NGAL menunjukkan hasil median 82,76 (67,59) yang lebih tinggi dibandingkan dengan kelompok pasien TBRO anemia dan kelompok TBRO tanpa anemia 59,24(91,98) namun tidak bermakna (p: 0,26). Terdapat korelasi yang bermakna kadar NGAL dengan leukosit (r:0,295, p:0,011), neutrofil (r:0,297, p:0,011), limfosit (r:-0,343,p:0,003) dan NLR (r:0,336,p:0,004). Kesimpulan: Terdapat peningkatan kadar NGAL pada pasien TBRO dengan anemia dibandingkan tanpa anemia namun tidak bermakna secara statistik. ......Background: Pulmonary tuberculosis (TB) remains one of the leading causes of morbidity and mortality worldwide. In the last two decades, drug-resistant tuberculosis (DR-TB) has emerged as a global health threat. NGAL is a neutrophil granulocyte- derived protein that undergoes maturation and becomes gelatinase. NGAL is involved in innate immunity by blocking bacteria from acquiring iron for growth. In patients with anemia, there is a reduction in innate immunity, in patient DR-TB with anemia allowing Mtb bacteria to obtain iron from the human body for replication. However, there is currently no data on serum NGAL protein levels in DR-TB patients with anemia. Methods: This study is an observational research using a cross-sectional design conducted in the outpatient clinic and inpatient ward of MDR RSUP Persahabatan in July-September 2023. The research subjects were 73 subject DR-TB patients who not yet started treatment with or without anemia and met the inclusion and exclusion criteria. Blood samples of the subjects were collected as much as 3cc. The blood serum was separated and stored in a -20°C freezer. Furthermore, ELISA examination using the sandwich technique was performed, and NGAL protein levels were measured. Results: In this study, DR-TB patients with anemia had BMI indicating significant malnutrition (p: 0.026, OR 2.9(1.1-7.5). This study also identified an increase in the number of neutrophils (p: 0.002, OR 0.2(0.06-0.5) and a decrease in the number of lymphocytes (p: 0.006, OR 4.2(1.4-9.8) in the anemia patient group, as reflected in the increased NLR (p: 0.028, OR 0.3(0.09-0.9). The findings also showed that DR-TB patients with anemia had statistically larger lung lesions (p: 0.048, OR 2.7(0.9-7.3). NGAL levels showed a higher median result between the DR-TB patient group with anemia 82,76 (67,59) and the group without anemia 59,24 (91,98), but it was not statistically significant (p: 0.26). NGAL have significant corelation among leukocyte (r:0,295, p:0,011), neutrophil (r:0,297,p:0,011), limphocyte (r:-0,343,p:0,003) and NLR (r:0,336,p:0,004) Conclusion: There is a increase in NGAL levels in DR-TB patients with anemia compared to those without anemia. However, this findings do not reach statistical significance.

Latar Belakang: Tumor sistem saraf pusat (SSP) merupakan salah satu penyebab utama morbiditas di seluruh dunia yang menyebabkan disabilitas dan penurunan kualitas hidup. Tumor SSP menyebabkan defisit neurologis dan berisiko terjadinya kaheksia. Kaheksia dihubungkan dengan penurunan respons pengobatan dan penurunan kesintasan. Peradangan sistemik merupakan ciri khas kaheksia. Rasio neutrofil limfosit (RNL) merupakan penanda inflamasi sistemik yang mudah dan rutin diperiksa dengan harga yang tidak mahal. Belum diketahui hubungan antara RNL dengan kejadian kaheksia pada tumor SSP. Metode: Studi potong lintang ini dilakukan pada subjek berusia 18–65 tahun di RSUPN Dr. Cipto Mangunkusumo, yang dirawat dengan diagnosis tumor SSP pada bulan November hingga Desember 2023. Nilai RNL diambil dari pemeriksaan darah perifer lengkap dan dilakukan penegakan diagnosis kaheksia berdasarkan kriteria Evans. Dilakukan analisis hubungan RNL dengan kejadian kaheksia. Hasil: Terdapat 50 subjek dengan diagnosis tumor SSP. Median RNL adalah 4,13 (1,26; 23,22). Nilai RNL secara signifikan lebih tinggi pada kelompok subjek yang mengalami kaheksia (median RNL 7,19 (1,26; 23,22)) dibandingkan tanpa kaheksia (median RNL 3,10 (1,40; 8,48)) (p<0,001). Simpulan: RNL berhubungan dengan kejadian kaheksia pada tumor SSP. Subjek yang mengalami kaheksia memiliki RNL yang lebih tinggi dibandingkan dengan yang tidak kaheksia. ......Background: Central nervous system (CNS) tumors are one of the leading causes of morbidity worldwide, causing disability and decreased quality of life. Central nervous system tumors cause neurological deficits and are at risk of developing cachexia. Cachexia is associated with decreased treatment response and reduced survival. Systemic inflammation is the hallmark of cachexia. Neutrophil lymphocyte ratio (NLR) is a systemic inflammation that included in routine laboratory examination and inexpensive. The association between NLR and the incidence of cachexia in CNS tumors remain unknown. Methods: This cross-sectional study was conducted on subjects aged 18–65 years old at RSUPN Dr. Cipto Mangunkusumo Hospital, who were admitted with CNS tumor diagnosis from November to December 2023. The NLR value was taken from the complete peripheral blood examination and the diagnosis of cachexia was based on Evans criteria. The relationship between NLR and the incidence of cachexia was analyzed. Results: There were 50 subjects with CNS tumor diagnosis. The median NLR was 4,13 (1,26; 23,22). The mean NLR was significantly higher in the group of subjects with cachexia (median NLR 7,19 (1,26; 23,22)) than without cachexia (median NLR 3,10 (1,40; 8,48)) (p<0,001). Conclusion: NLR is associated with the incidence of cachexia in CNS tumors. Subjects with cachexia had higher NLR compared to those withoit cachexia.
