ABSTRAKLatar Belakang : Kebocoran plasma merupakan proses utama yang terjadi pada
demam berdarah dengue (DBD) dimana mulai terjadi pada hari ke-3 demam dan
mencapai puncaknya pada hari ke-5 demam. Kebocoran plasma menyebabkan
hipoksia jaringan yang berakibat asidosis. Variabel yang terkait dengan
mikrosirkulasi perfusi jaringan yaitu parameter asam-basa. Menurut Stewart,
abnormalitas asam-basa metabolik ditentukan dengan menghitung Strong Ion
Difference (SID). Hingga saat ini belum diketahui nilai SID pada infeksi dengue
dewasa dengan kebocoran plasma.
Tujuan Penelitian : Mengetahui peran nilai SID untuk memprediksi dan
mendiagnosis kebocoran plasma pada infeksi dengue pasien dewasa.
Metode : Studi potong lintang dan kohort retrospektif, pada infeksi virus dengue
pasien dewasa yang dirawat di ruang penyakit dalam RSUPN Cipto
Mangunkusumo dan RSUP Persahabatan Jakarta. Dilakukan pemeriksaan nilai
SID untuk melihat perbedaan rerata nilai SID antara demam dengue (DD) dan
DBD dengan uji t tidak berpasangan, dan nilai titik potong SID pada keadaan
dengan atau tanpa kebocoran plasma dilakukan dengan menentukan sensitivitas
dan spesifisitas terbaik dari kurva ROC.
Hasil : Jumlah subjek sebanyak 57 orang. Jenis kelamin laki-laki sebanyak 31
pasien (54,38%) dan perempuan 26 pasien (45,61%). Kasus DD 31 pasien
(54,38%) dan kasus DBD 26 pasien. Nilai SID hari ke-3 pada DBD secara
bermakna lebih rendah dibandingkan DD [36,577 (±2,08) dan 39,032 (±1,44);
p<0,01]. Demikian pula pada hari ke-5, nilai SID pada DBD lebih rendah
dibandingkan DD [34,423 (±2,36) dan 37,548 (±2,55); p<0,01]. Hasil analisis
statistik didapatkan perbedaan bermakna. Berdasarkan kurva ROC pada hari ke-3
didapatkan nilai SID ≤37,5 sebagai titik potong yang memberikan sensitivitas
65% dan spesifisitas 84% dengan Area Under Curve (AUC) 0,824 (IK 95% 0,71
? 0,93; p<0,001). Pada hari ke-5, titik potong nilai SID ≤36,5 memberikan
sensitivitas 81% dan spesifisitas 68% dengan AUC 0,813 (IK 95% 0,7 ? 0,92;
p<0,001).
Kesimpulan : Nilai SID hari ke-3 dan hari ke-5 pada DBD lebih rendah
dibandingkan DD. Nilai SID ≤37,5 pada hari ke-3 dan ≤36,5 pada hari ke-5 dapat
dipakai sebagai petanda kebocoran plasma.
ABSTRACTBackground : Plasma leakage is the main process in dengue haemorrhagic fever
(DHF) which starts at day 3 of fever and peaked at day 5 of fever. Plasma leakage
is causing tissue hypoxia that resulting in acidosis. Tissue perfusion
microcirculation-associated variable is acid-base parameters. According to
Stewart, abnormality of metabolic acid-base is determined by calculating Strong
Ion Difference (SID). Now, SID in adult dengue-infected patients with plasma
leakage is not known yet.
Objectives : To detemine the role of SID in prediction and diagnosis of plasma
leakage in adult dengue-infected patients.
Methods : These were cross-sectional and retrospective cohort study which
conducted in adult dengue-infected patients that hospitalized in internal medicine
ward of Cipto Mangunkusumo General Hospital and Persahabatan General
Hospital in Jakarta. SID was examined to determine the mean difference between
dengue fever (DF) and DHF by t-test independent, and cut-off point of SID in
plasma leakage was identified by sensitivity and specificity based on ROC curve.
Results : There were 57 adult dengue-infected patients recruited; consist of 31
male patients (54,38%) and 26 female patient (45,61%); 31 DF patients (54,38%)
and 26 DHF patients (45,6%). SID on day 3 of fever in DHF was significantly
lower than DF [36,577 (±2,08) vs 39,032 (±1,44); p<0,01]. Similarly on day 5,
SID of DHF 36,577 (±2,08) vs DF 39,032 (±1,44); p<0,01. Based on ROC curve
of day 3, the cut-off point of SID was ≤37,5 with sensitivity 65%, specificity 84%,
Area Under Curve (AUC) 0,824 (95% CI 0,71 ? 0,93; p<0,001). On day 5, the
cut-off points of SID was <36,5 with sensitivity 81%, specificity 68%, AUC 0,813
(95% CI 0,7 ? 0,92; p<0,001).
Conclusion : SID on day 3 and day 5 of fever in DHF was significantly lower
than DF. SID ≤37,5 on day 3 and ≤36,5 on day 5 can be used as a marker of
plasma leakage.
