ABSTRAK
Latar Belakang : Sepsis memiliki mortalitas yang tinggi, dengan insiden yang semakin meningkat. Jenis mikroorganisme etiologi sepsis berhubungan dengan keparahan dan mortalitas pasien sepsis, dimana sepsis Gram negatif merupakan kelompok dengan keparahan dan mortalitas tertinggi. Kultur darah merupakan baku standar diagnosis etiologi sepsis dan dasar pemberian antimikroba definit, namun angka keberhasilannya rendah dan membutuhkan waktu beberapa hari. Pemeriksaan prokalsitonin (PCT) memiliki sensitivitas tinggi terhadap infeksi bakteri dan nilainya berbeda pada berbagai hasil kultur darah pasien sepsis. Belum ada data profil PCT pada pasien sepsis di Indonesia dan belum ada studi profil PCT pada sepsis non-bakteremia dengan fokus infeksi Gram negatif.Tujuan : Mendapatkan data profil PCT pada berbagai kelompok pasien sepsis.Metode : Penelitian ini merupakan studi potong lintang retrospektif terhadap data sekunder rekam medis dan laboratorium pasien sepsis yang dirawat di RSCM selama Januari 2013 ? Desember 2015. Dengan metode konsekutif subyek penelitian dikelompokkan berdasarkan etiologi sepsis.Hasil : Nilai median PCT pada sepsis bakteremia Gram negatif, bakteremia Gram positif, fungemia, dan sepsis non bakteremia dengan fokus infeksi Gram negatif berturut-turut 13,9 ng/mL, 2,73 ng/mL, 2,56 ng/mL, dan 5,25 ng/mL. Berdasarkan derajat keparahan sepsis, nilai median PCT tertinggi didapatkan pada syok sepsis pada kelompok bakteremia Gram negatif (65,16 ng/mL).

ABSTRACT
Background : Sepsis has high mortality rate, and its incidence has been increasing recently. Microbes types as sepsis etiology are related to severity and mortality of septic patients. Gram-negative sepsis is the highest severity and mortality group of septic patients. Blood culture is gold standard to confirm etiology of sepsis and guidance for administration of definit antimicrobes, but its success rate is low and needs some days for the results Procalcitonin (PCT) has high sensitivity for bacterial infection, and it has different levels due to various results of blood cultures of septic patients. There are no datas about PCT profile in septic patients in Indonesia, and no studies before about PCT profile in non-bacteremia sepsis with Gram-negative focal infection.Aim: To obtain PCT profile in various groups of septic patients.Method: A cross-sectional retrospective study was conducted to collect medical records and laboratory datas of septic patients at RSCM during January 2013 until December 2015. By consecutive sampling subjects were grouping base on sepsis etiology.Result : PCT median values of Gram-negative bacteremia, Gram-positive bacteremia, fungemia, and non-bacteremia sepsis with Gram-negative focal infection are 13.9 ng/mL, 2.73 ng/mL, 2.56 ng/mL, and 5.25 ng/mL. Base on severity of sepsis, the highest level of PCT median (65.16 ng/mL) is found in septic shock in Gram-negative bacteremia group.Conclusion: Gram-negative bacteremia sepsis has the highest level of PCT median.
