    Abstract
    Sistemik Lupus Eritematosus (SLE) merupakan proses autoantibodi terhadap inti sel dan imun kompleks yang akan mengaktivasi sistem inflamasi menyebabkan ambang rangsang aktivasi trombosit menjadi lebih rendah. Beberapa penelitian melaporkan bahwa Mean Platelet Volume (MPV), Platelet distribution width (PDW) merupakan marker yang baik terhadap aktivitas perjalanan penyakit SLE. Evaluasi aktivitas SLE menggunakan indeks MEX-SLEDAI berguna dalam panduan dalam pemberian terapi serta tingginya angka kematian SLE akibat active disease (flare), perlu mendapat perhatian khusus. Tujuan penelitian ini adalah mengetahui perbedaan nilai MPV dan PDW antara kelompok flare dengan non flare pada pasien SLE. Penelitian ini mendapatkan perbedaan secara signifikan nilai MPV antara kelompok flare dibandingkan non flare yaitu [9,025±2,016 vs. 10,350 ± 1,094, (p=0,02)] sedangkan nilai PDW yang tidak signifikan secara statistik [11,750±3,140 vs. 10,560 ± 2,130, (p=0,083)]. Berdasarkan plot kurva (Receiver Operating Characteristic) ROC didapatkan nilai cutoff untuk MPV adalah 9,15 fl dengan nilai sensitivitas (90,6%) dan spesitifisitas (66%). MPV dapat digunakan sebagai marker untuk menilai aktivitas perjalanan penyakit SLE.
     
    Systemic Lupus Erythematosus (SLE) is an autoantibodies process against the cell nucleus and immune complex that will activate the inflammatory system causing the excitatory threshold of platelet activation to be lower. Several studies before have reported that the Mean Platelet Volume (MPV) and Platelet distribution width (PDW) could be used as markers of SLE disease activity. Evaluation of SLE activity using the MEX-SLEDAI index is useful in guidance in providing therapy, and the high mortality rate of SLE due to active disease (flare) needs special attention. This study aimed to determine the difference in MPV and PDW values between flare and non-flare groups in SLE patients. The study found a significant difference in MPV values between flare groups compared to non-flares of [9,025±2,016 vs. 10,350 ± 1,094, (p=0.02)] while PDW values are not statistically significant [11,750±3,140 vs. 10,560 ± 2,130, (p=0.083)]. Based on Receiver Operating Characteristic (ROC) curve obtained, the cutoff value for MPV is 9.15 fl with sensitivity value (90.6%) and specificity (66%). MPV value can be used as a biomarker to assess the activity of the disease course of SLE.
